WL#3072 Maria Recovery
misc fixes of execution of UNDOs in the UNDO phase:
- into the CLR_END, store the LSN of the _previous_ UNDO (we debated
what was best, so far we're going with "previous"; later we can change
to "current" if needed), and store the type of record which is being
undone (needed to know how to update state.records when we see the
CLR_END during the REDO phase).
- declaring all UNDOs and CLR_END as "compressed"
- when executing an UNDO in the UNDO phase, state.records is updated
as a hook when writing CLR_END (needed for "recovery of the state"),
and so is trn->undo_lsn (needed for when we have checkpoints).
- bugfix (execution of UNDO_ROW_DELETE didn't store the correct checksum
into the re-inserted row, maria_chk -r thus threw the row away).
- modifications of ma_test1: where to stop is now driven by --testflag;
--test-undo just tells how to stop (flush data, flush log, nothing).
- ma_test_recovery: testing of the UNDO phase, more testing of the
REDO phase, identification of a bug.
storage/maria/ma_blockrec.c:
- bugfix: execution of UNDO_ROW_DELETE didn't store the correct
checksum into the row (leading to "maria_chk -r" eliminating the
re-inserted row, net effect was that rollback appeared to have
rolled back no deletion). Reason was that write_block_record() used
info->cur_row.checksum, while "row" can be != &info->cur_row
(case of UNDO_ROW_DELETE). After fixing this, problems with
_ma_update_block_record() appeared; indeed checksum was computed
by allocate_and_write_block_record() while _ma_update_block_record()
directly calls write_block_record(). Solution is to compute checksum
in write_block_record() instead.
- when executing an UNDO, we now pass the LSN of the _previous_ UNDO
to block_format functions. This LSN can be 0 (if the being-executed UNDO
was the transaction's first UNDO), so "undo_lsn==0" cannot work
anymore to indicate "this is not UNDO work". Using undo_lsn==LSN_ERROR
instead (this is an impossible LSN).
- store into CLR_END the type of log record which was undone
(INSERT/UPDATE/DELETE); needed for Recovery to know if/how it has
to update state.records if it sees this CLR_END in the REDO phase.
- when writing the CLR_END in _ma_apply_undo_row_insert(),
the place to store file's id is log_data+LSN_STORE_SIZE.
- in _ma_apply_undo_row_insert(), the records-- is moved
to a hook when writing the CLR_END (this way it is under log's mutex
which is needed for "recovery of the state")
storage/maria/ma_loghandler.c:
- all UNDOs, and CLR_END, start with the LSN of another UNDO; so
we can declare them "compressed".
- write_hook_for_clr_end() to set trn->undo_lsn (to the previous
UNDO's LSN) under log's lock (like UNDOs set trn->undo_lsn under log's
lock), and also update, if appropriate, state.records.
- reset share->id to 0 when deassigning; not useful for now but
sounds logical.
storage/maria/ma_recovery.c:
- if no table is found for a REDO, it's not an error; for an UNDO, it is
- in the REDO phase, when we see a CLR_END we must update trn->undo_lsn
and sometimes state.records.
- in the UNDO phase, when we execute an UNDO_ROW_INSERT:
* update trn->undo_lsn only after executing the record
* store the _previous_ undo_lsn into the CLR_END
- at the end of the REDO phase, when we recreate TRN objects, they
have already their long id in the log (either via a
LOGREC_LONG_TRANSACTION_ID, or in a checkpoint record), don't write
a new, useless LOGREC_LONG_TRANSACTION_ID for them.
storage/maria/ma_test1.c:
* where to stop execution is now driven by --testflag and not --test-undo
(ma_test2 already has --testflag for the same purpose). This allows
us to do a clean stop (with commit) at any point.
* --test-undo=# tells how to abort (flush all pages (which implies
flushing log) or only log or nothing); all such "ways of crashing"
are tested in ma_test_recovery
storage/maria/ma_test_recovery:
* Testing execution of UNDOs, with and without BLOBs.
* Testing idempotency of REDOs.
* See @todo for a probable bug with BLOBs.
* maria_chk -rq instead of -r, as with -q it nicely stops on any
problem in the data file (like the checksum bug see comment of
ma_blockrec.c).
* Testing if log was written by UNDO phase (often expected),
not written by REDO phase (always expected).
* Less output on the screen, compares with expected output in the end.
* some shell thingies like "set --" and $# are courtesy of
Danny and Pekka.
storage/maria/maria_read_log.c:
when only displaying the records, don't do an UNDO phase
storage/maria/ma_test_recovery.expected:
This is the expected output of a great part of ma_test_recovery.
ma_test_recovery compares its output to the expected output
and tells if different.
If we look at this file it mentions differences in checksum
(normal, it's not recovered yet) and in records count
(getting a correct records' count when recovery starts on an
already existing table, like when testing rollback,
is coded but not yet pushed).

Testing the REDO PHASE ALONE
|
- speed optimization:
minimize writes to transactional Maria tables: don't write
data pages, state, and open_count at the end of each statement.
Data pages will be written by a background thread periodically.
State will be written by Checkpoint periodically.
open_count serves to detect when a table is potentially damaged
due to an unclean mysqld stop, but thanks to recovery an unclean
mysqld stop will be corrected and so open_count becomes useless.
As state is written less often, it is often obsolete on disk,
we thus should avoid to read it from disk.
- by removing the data page writes above, it is necessary to put
it back at the start of some statements like check, repair and
delete_all. It was already necessary in fact (see ma_delete_all.c).
- disabling CACHE INDEX on Maria tables for now (fixes crash
of test 'key_cache' when run with --default-storage-engine=maria).
- correcting some fishy code in maria_extra.c (we possibly could lose
index pages when doing a DROP TABLE under Windows, in theory).
storage/maria/ha_maria.cc:
disable CACHE INDEX in Maria for now (there is a single cache for now),
it crashes and it's not a priority
storage/maria/ma_bitmap.c:
debug message
storage/maria/ma_check.c:
The statement before maria_repair() may not flush state,
so it needs to be done by maria_repair() (indeed this function
uses maria_open(HA_OPEN_COPY) so reads state from disk,
so needs to find it up-to-date on disk).
For safety (but normally this is not needed) we remove index blocks
out of the cache before repairing.
_ma_flush_blocks() becomes _ma_flush_table_files_after_repair():
it now additionally flushes the data file and state and syncs files.
As a side effect, the assertion "no WRITE_CACHE_USED" from
_ma_flush_table_files() fired so we move all end_io_cache() done
at the end of repair to before the calls to _ma_flush_table_files_after_repair().
storage/maria/ma_close.c:
when closing a transactional table, we fsync it. But we need to
do this only after writing its state.
We need to write the state at close time only for transactional
tables (the other tables do that at last unlock).
Putting back the O_RDONLY||crashed condition which I had
removed earlier.
Unmap the file before syncing it (does not matter now as Maria
does not use mmap)
storage/maria/ma_delete_all.c:
need to flush data pages before chsize-ing it. Was needed even when
we flushed data pages at the end of each statement, because we didn't
anyway do it if under LOCK TABLES: the change here thus fixes this bug:
create table t(a int) engine=maria;lock tables t write;
insert into t values(1);delete from t;unlock tables;check table t;
"Size of datafile is: 16384 Should be: 8192"
(an obsolete page went to disk after the chsize(), at unlock time).
storage/maria/ma_extra.c:
When doing share->last_version=0, we make the MARIA_SHARE-in-memory
invisible to future openers, so need to have an up-to-date state
on disk for them. The same way, future openers will reopen the data
and index file, so they will not find our cached blocks, so we
need to flush them to disk.
In HA_EXTRA_FORCE_REOPEN, this probably happens naturally as all
tables normally get closed, we however add a safety flush.
In HA_EXTRA_PREPARE_FOR_RENAME, we need to do the flushing. On
Windows we additionally need to close files.
In HA_EXTRA_PREPARE_FOR_DROP, we don't need to flush anything but
remove dirty cached blocks from memory. On Windows we need to close
files.
Closing files forces us to sync them before (requirement for transactional
tables).
For mutex reasons (don't lock intern_lock twice), we move
maria_lock_database() and _ma_decrement_open_count() first in the list
of operations.
Flush also data file in HA_EXTRA_FLUSH.
storage/maria/ma_locking.c:
For transactional tables:
- don't write data pages / state at unlock time;
as a consequence, "share->changed=0" cannot be done.
- don't write state in _ma_writeinfo()
- don't maintain open_count on disk (Recovery corrects the table in case of crash
anyway, and we gain speed by not writing open_count to disk),
For non-transactional tables, flush the state at unlock only
if the table was changed (optimization).
Code which read the state from disk is relevant only with
external locking, we disable it (if want to re-enable it, it shouldn't
for transactional tables as state on disk may be obsolete (such tables
does not flush state at unlock anymore).
The comment "We have to flush the write cache" is now wrong because
maria_lock_database(F_UNLCK) now happens before thr_unlock(), and
we are not using external locking.
storage/maria/ma_open.c:
_ma_state_info_read() is only used in ma_open.c, making it static
storage/maria/ma_recovery.c:
set MARIA_SHARE::changed to TRUE when we are going to apply a
REDO/UNDO, so that the state gets flushed at close.
storage/maria/ma_test_recovery.expected:
Changes introduced by this patch:
- good: the "open" (table open, not properly closed) is gone,
it was pointless for a recovered table
- bad: stemming from different moments of writing the index's state
probably (_ma_writeinfo() used to write the state after every row
write in ma_test* programs, doesn't anymore as the table is
transactional): some differences in indexes (not relevant as we don't
yet have recovery for them); some differences in count of records
(changed from a wrong value to another wrong value) (not relevant
as we don't recover this count correctly yet anyway, though
a patch will be pushed soon).
storage/maria/ma_test_recovery:
for repeatable output, no names of varying directories.
storage/maria/maria_chk.c:
function renamed
storage/maria/maria_def.h:
Function became local to ma_open.c. Function renamed.

WL#3072 Maria Recovery
misc fixes of execution of UNDOs in the UNDO phase:
- into the CLR_END, store the LSN of the _previous_ UNDO (we debated
what was best, so far we're going with "previous"; later we can change
to "current" if needed), and store the type of record which is being
undone (needed to know how to update state.records when we see the
CLR_END during the REDO phase).
- declaring all UNDOs and CLR_END as "compressed"
- when executing an UNDO in the UNDO phase, state.records is updated
as a hook when writing CLR_END (needed for "recovery of the state"),
and so is trn->undo_lsn (needed for when we have checkpoints).
- bugfix (execution of UNDO_ROW_DELETE didn't store the correct checksum
into the re-inserted row, maria_chk -r thus threw the row away).
- modifications of ma_test1: where to stop is now driven by --testflag;
--test-undo just tells how to stop (flush data, flush log, nothing).
- ma_test_recovery: testing of the UNDO phase, more testing of the
REDO phase, identification of a bug.
storage/maria/ma_blockrec.c:
- bugfix: execution of UNDO_ROW_DELETE didn't store the correct
checksum into the row (leading to "maria_chk -r" eliminating the
re-inserted row, net effect was that rollback appeared to have
rolled back no deletion). Reason was that write_block_record() used
info->cur_row.checksum, while "row" can be != &info->cur_row
(case of UNDO_ROW_DELETE). After fixing this, problems with
_ma_update_block_record() appeared; indeed checksum was computed
by allocate_and_write_block_record() while _ma_update_block_record()
directly calls write_block_record(). Solution is to compute checksum
in write_block_record() instead.
- when executing an UNDO, we now pass the LSN of the _previous_ UNDO
to block_format functions. This LSN can be 0 (if the being-executed UNDO
was the transaction's first UNDO), so "undo_lsn==0" cannot work
anymore to indicate "this is not UNDO work". Using undo_lsn==LSN_ERROR
instead (this is an impossible LSN).
- store into CLR_END the type of log record which was undone
(INSERT/UPDATE/DELETE); needed for Recovery to know if/how it has
to update state.records if it sees this CLR_END in the REDO phase.
- when writing the CLR_END in _ma_apply_undo_row_insert(),
the place to store file's id is log_data+LSN_STORE_SIZE.
- in _ma_apply_undo_row_insert(), the records-- is moved
to a hook when writing the CLR_END (this way it is under log's mutex
which is needed for "recovery of the state")
storage/maria/ma_loghandler.c:
- all UNDOs, and CLR_END, start with the LSN of another UNDO; so
we can declare them "compressed".
- write_hook_for_clr_end() to set trn->undo_lsn (to the previous
UNDO's LSN) under log's lock (like UNDOs set trn->undo_lsn under log's
lock), and also update, if appropriate, state.records.
- reset share->id to 0 when deassigning; not useful for now but
sounds logical.
storage/maria/ma_recovery.c:
- if no table is found for a REDO, it's not an error; for an UNDO, it is
- in the REDO phase, when we see a CLR_END we must update trn->undo_lsn
and sometimes state.records.
- in the UNDO phase, when we execute an UNDO_ROW_INSERT:
* update trn->undo_lsn only after executing the record
* store the _previous_ undo_lsn into the CLR_END
- at the end of the REDO phase, when we recreate TRN objects, they
have already their long id in the log (either via a
LOGREC_LONG_TRANSACTION_ID, or in a checkpoint record), don't write
a new, useless LOGREC_LONG_TRANSACTION_ID for them.
storage/maria/ma_test1.c:
* where to stop execution is now driven by --testflag and not --test-undo
(ma_test2 already has --testflag for the same purpose). This allows
us to do a clean stop (with commit) at any point.
* --test-undo=# tells how to abort (flush all pages (which implies
flushing log) or only log or nothing); all such "ways of crashing"
are tested in ma_test_recovery
storage/maria/ma_test_recovery:
* Testing execution of UNDOs, with and without BLOBs.
* Testing idempotency of REDOs.
* See @todo for a probable bug with BLOBs.
* maria_chk -rq instead of -r, as with -q it nicely stops on any
problem in the data file (like the checksum bug see comment of
ma_blockrec.c).
* Testing if log was written by UNDO phase (often expected),
not written by REDO phase (always expected).
* Less output on the screen, compares with expected output in the end.
* some shell thingies like "set --" and $# are courtesy of
Danny and Pekka.
storage/maria/maria_read_log.c:
when only displaying the records, don't do an UNDO phase
storage/maria/ma_test_recovery.expected:
This is the expected output of a great part of ma_test_recovery.
ma_test_recovery compares its output to the expected output
and tells if different.
If we look at this file it mentions differences in checksum
(normal, it's not recovered yet) and in records count
(getting a correct records' count when recovery starts on an
already existing table, like when testing rollback,
is coded but not yet pushed).

WL#3071 Maria checkpoint
Ability for flush_pagecache_blocks() to flush only certain pages of
a file, as instructed by an option "filter" pointer-to-function argument;
Checkpoint and background dirty page flushing use that to flush only
pages which have been dirty for long enough and bitmap pages.
Fix for a bug in flush_cached_blocks() (no idea if it could produce
a bug in real life, but theoretically it is).
Testing checkpoint in ma_test_recovery via ma_test1 and ma_test2.
Background checkpoint & dirty pages flush thread is still disabled
by default in ha_maria.
mysql-test/r/maria.result:
result update
storage/maria/ha_maria.cc:
blank after function comment
storage/maria/ma_checkpoint.c:
Using an enum instead of 0/1/2 (applying Sanja's review comments).
The comment about "this is an horizon" can be removed as Sanja
created translog_next_LSN() which parse_checkpoint_record() uses.
Variables in ma_checkpoint_background() cannot be declared in the
for() as their value must not be reset at each iteration!
storage/maria/ma_pagecache.c:
adding to flush_pagecache_blocks() optional arguments 'filter'
(pointer to function) and 'filter_arg'; if filter!=NULL this function
will be called for each block of the file and will reply if this
block and following ones should be flushed or not (3 possible
replies).
Fixing a bug when flush_cached_blocks() skips a pinned page: it has
to unset PCBLOCK_IN_FLUSH set by flush_pagecache_blocks_int().
storage/maria/ma_pagecache.h:
flush_pagecache_blocks() is changed to take "filter" and "filter_arg"
arguments. "filter", if it is not NULL, may return one value
among enum pagecache_flush_filter_result.
storage/maria/ma_recovery.c:
open_count=0 when closing tables at the end of recovery.
storage/maria/ma_test1.c:
Optional checkpoints (-H#) at various stages (stages similar
to --testflag), for testing of checkpoints.
storage/maria/ma_test2.c:
Optional checkpoints (-H#) at various stages (stages similar
to -t), for testing of checkpoints.
storage/maria/ma_test_recovery.expected:
Result update: the results of the additional test run with -H#
(checkpoints) are added here. They are exactly identical to without
checkpoints except that the index's Root (printed by maria_chk)
is more correct when using checkpoints. This is because checkpoint
flushed the state, so it happens to be correct, while no-checkpoint
does not flush the state, and recovery does not recover indexes
so Root is never fixed. When we recover indices, this will go away.
storage/maria/ma_test_recovery:
We duplicate the loop of tests to add an additional run with
checkpoints at various stages, to see if maria_read_log
uses them fine.

and so is trn->undo_lsn (needed for when we have checkpoints).
- bugfix (execution of UNDO_ROW_DELETE didn't store the correct checksum
into the re-inserted row, maria_chk -r thus threw the row away).
- modifications of ma_test1: where to stop is now driven by --testflag;
--test-undo just tells how to stop (flush data, flush log, nothing).
- ma_test_recovery: testing of the UNDO phase, more testing of the
REDO phase, identification of a bug.
storage/maria/ma_blockrec.c:
- bugfix: execution of UNDO_ROW_DELETE didn't store the correct
checksum into the row (leading to "maria_chk -r" eliminating the
re-inserted row, net effect was that rollback appeared to have
rolled back no deletion). Reason was that write_block_record() used
info->cur_row.checksum, while "row" can be != &info->cur_row
(case of UNDO_ROW_DELETE). After fixing this, problems with
_ma_update_block_record() appeared; indeed checksum was computed
by allocate_and_write_block_record() while _ma_update_block_record()
directly calls write_block_record(). Solution is to compute checksum
in write_block_record() instead.
- when executing an UNDO, we now pass the LSN of the _previous_ UNDO
to block_format functions. This LSN can be 0 (if the being-executed UNDO
was the transaction's first UNDO), so "undo_lsn==0" cannot work
anymore to indicate "this is not UNDO work". Using undo_lsn==LSN_ERROR
instead (this is an impossible LSN).
- store into CLR_END the type of log record which was undone
(INSERT/UPDATE/DELETE); needed for Recovery to know if/how it has
to update state.records if it sees this CLR_END in the REDO phase.
- when writing the CLR_END in _ma_apply_undo_row_insert(),
the place to store file's id is log_data+LSN_STORE_SIZE.
- in _ma_apply_undo_row_insert(), the records-- is moved
to a hook when writing the CLR_END (this way it is under log's mutex
which is needed for "recovery of the state")
storage/maria/ma_loghandler.c:
- all UNDOs, and CLR_END, start with the LSN of another UNDO; so
we can declare them "compressed".
- write_hook_for_clr_end() to set trn->undo_lsn (to the previous
UNDO's LSN) under log's lock (like UNDOs set trn->undo_lsn under log's
lock), and also update, if appropriate, state.records.
- reset share->id to 0 when deassigning; not useful for now but
sounds logical.
storage/maria/ma_recovery.c:
- if no table is found for a REDO, it's not an error; for an UNDO, it is
- in the REDO phase, when we see a CLR_END we must update trn->undo_lsn
and sometimes state.records.
- in the UNDO phase, when we execute an UNDO_ROW_INSERT:
* update trn->undo_lsn only after executing the record
* store the _previous_ undo_lsn into the CLR_END
- at the end of the REDO phase, when we recreate TRN objects, they
have already their long id in the log (either via a
LOGREC_LONG_TRANSACTION_ID, or in a checkpoint record), don't write
a new, useless LOGREC_LONG_TRANSACTION_ID for them.
storage/maria/ma_test1.c:
* where to stop execution is now driven by --testflag and not --test-undo
(ma_test2 already has --testflag for the same purpose). This allows
us to do a clean stop (with commit) at any point.
* --test-undo=# tells how to abort (flush all pages (which implies
flushing log) or only log or nothing); all such "ways of crashing"
are tested in ma_test_recovery
storage/maria/ma_test_recovery:
* Testing execution of UNDOs, with and without BLOBs.
* Testing idempotency of REDOs.
* See @todo for a probable bug with BLOBs.
* maria_chk -rq instead of -r, as with -q it nicely stops on any
problem in the data file (like the checksum bug see comment of
ma_blockrec.c).
* Testing if log was written by UNDO phase (often expected),
not written by REDO phase (always expected).
* Less output on the screen, compares with expected output in the end.
* some shell thingies like "set --" and $# are courtesy of
Danny and Pekka.
storage/maria/maria_read_log.c:
when only displaying the records, don't do an UNDO phase
storage/maria/ma_test_recovery.expected:
This is the expected output of a great part of ma_test_recovery.
ma_test_recovery compares its output to the expected output
and tells if different.
If we look at this file it mentions differences in checksum
(normal, it's not recovered yet) and in records count
(getting a correct records' count when recovery starts on an
already existing table, like when testing rollback,
is coded but not yet pushed).

WL#3071 Maria checkpoint
Ability for flush_pagecache_blocks() to flush only certain pages of
a file, as instructed by an option "filter" pointer-to-function argument;
Checkpoint and background dirty page flushing use that to flush only
pages which have been dirty for long enough and bitmap pages.
Fix for a bug in flush_cached_blocks() (no idea if it could produce
a bug in real life, but theoretically it is).
Testing checkpoint in ma_test_recovery via ma_test1 and ma_test2.
Background checkpoint & dirty pages flush thread is still disabled
by default in ha_maria.
mysql-test/r/maria.result:
result update
storage/maria/ha_maria.cc:
blank after function comment
storage/maria/ma_checkpoint.c:
Using an enum instead of 0/1/2 (applying Sanja's review comments).
The comment about "this is an horizon" can be removed as Sanja
created translog_next_LSN() which parse_checkpoint_record() uses.
Variables in ma_checkpoint_background() cannot be declared in the
for() as their value must not be reset at each iteration!
storage/maria/ma_pagecache.c:
adding to flush_pagecache_blocks() optional arguments 'filter'
(pointer to function) and 'filter_arg'; if filter!=NULL this function
will be called for each block of the file and will reply if this
block and following ones should be flushed or not (3 possible
replies).
Fixing a bug when flush_cached_blocks() skips a pinned page: it has
to unset PCBLOCK_IN_FLUSH set by flush_pagecache_blocks_int().
storage/maria/ma_pagecache.h:
flush_pagecache_blocks() is changed to take "filter" and "filter_arg"
arguments. "filter", if it is not NULL, may return one value
among enum pagecache_flush_filter_result.
storage/maria/ma_recovery.c:
open_count=0 when closing tables at the end of recovery.
storage/maria/ma_test1.c:
Optional checkpoints (-H#) at various stages (stages similar
to --testflag), for testing of checkpoints.
storage/maria/ma_test2.c:
Optional checkpoints (-H#) at various stages (stages similar
to -t), for testing of checkpoints.
storage/maria/ma_test_recovery.expected:
Result update: the results of the additional test run with -H#
(checkpoints) are added here. They are exactly identical to without
checkpoints except that the index's Root (printed by maria_chk)
is more correct when using checkpoints. This is because checkpoint
flushed the state, so it happens to be correct, while no-checkpoint
does not flush the state, and recovery does not recover indexes
so Root is never fixed. When we recover indices, this will go away.
storage/maria/ma_test_recovery:
We duplicate the loop of tests to add an additional run with
checkpoints at various stages, to see if maria_read_log
uses them fine.

Added --debug-on option to mysqld (to be able to turn of DBUG with --debug-on=0)
Fixed some bugs with 'non_flushable' marking of bitmap pages
Don't use 'non_flushable' marking of bitmap pages for not transactional tables
SHOW CREATE TABLE now shows if table was created with page checksums
Fixed a lot of bugs with BLOB handling in case of update/REDO and UNDO
More tests (especially for blobs) and DBUG_ASSERTS()
More readable output from maria_read_log and maria_chk
Fixed wrong shift that caused Maria to crash on files > 4G
Mark tables as crashed of REDO fails
dbug/dbug.c:
Changed to use my_bool (allowed me to remove some windows specific code)
Added variable _dbug_on_ to speed up execution when DBUG is not going to be used
Removed initialization of variables if not needed
include/my_dbug.h:
Use my_bool for some functions that was defined as BOOLEAN in dbug.c code

storage/maria/Makefile.am:
Added ma_test_big.sh
storage/maria/ha_maria.cc:
Store in create_info if page checksums are used (For SHOW CREATE TABLE)
storage/maria/ma_bitmap.c:
Added _ma_bitmap_wait_or_flush() to cause reader of bitmap pages to wait with reading until bitmap is flushed.
Use TAIL_PAGE_COUNT_MARKER for tail pages
Set 'sub_blocks' for and only for the head page or for the first extent of a blob. This is needed for store_extent_info() to be able to set START_EXTENT_BIT's
Don't allocate more than 0x3ffff pages in one extent (We need bit 0x4000 as a START_EXTENT_BIT)
Increase the calculated 'head_length' with the number of bytes used for extents.
Update row->space_on_head_page also in _ma_bitmap_find_new_place()
Make _ma_bitmap_get_page_bits() global. (Needed for UNDO handling)
Changed _ma_bitmap_flushable() to take MARIA_HA instead of MARIA_SHARE.
This was needed to be able to mark the handler if we had a 'non_flushable' call pending or not.
Don't use 'non_flushable' marking of bitmap pages for not transactional tables.
Added BLOCKUSED_USE_ORG_BITMAP handling also for tail pages.
Added more DBUG_ASSERT() to find possible errors in other code

storage/maria/ma_blockrec.c:
UNDO of rows now puts back all part of the row on their original pages and positions.
Changed UNDO of DELETE and UNDO of UPDATE to contain information about the original length of data on head block and also extent information
This changes a lot of logic as now an insert of a row on a page may happen to any position (and not just to the first or next free)
Use PAGE_COUNT to mark if an extent is the start of of a blob. (Needed for extent_to_bitmap_blocks())
Added check_directory() for checking that directroy entries are correct.
Added checking of row checksums when reading rows (with EXTRA_DEBUG)
Added make_space_for_directory() and extend_directory() for doing expansion of directory
Added get_rowpos_in_head_or_tail_page() to be able to store head/tail on original position in UNDO

Changed find_free_position() to use make_space_for_directory()
Changed make_empty_page() to allow optional creation of directory entry
Changed delete_head_or_tail() and _ma_apply_undo_row_isnert() to not copy pagecache block (speed optimization)
Changed _ma_apply_redo_insert_row_head_or_tail() to be able to insert new row at any position on 'new' page
Changed _ma_apply_undo_row_delete() and _ma_apply_undo_row_update() to put row in it's original position
Ensure allocation of tail blocks are of at least MIN_TAIL_SIZE.
Ensure we store pages in pinned pages even if read failed. (If not we will have pages pinned forever in page cache)
Write original extent information in UNDO entry, not compacted ones (we need position to tails!)
When setting BLOCKUSED_USED, don't clear other bits (we have to preserve BLOCKUSED_USE_ORG_BITMAP)
Fixed som bugs in directory handling
Fixed bug where we wrote wrong lsn to blob pages
Added separate blob_buffer for fixing bug when updating row that had char/varchar that spanned several pages and also had blobs
Ensure we call _ma_bitmap_flushable() also in case of errors
When doing an update, first delete old entries, then search in bitmap for where to put new information
Info->s -> share
Rowid -> rowid
More DBUG_ASSERT()
storage/maria/ma_blockrec.h:
Added START_EXTENT_BIT and TAIL_PAGE_COUNT_MARKER
Added _ma_bitmap_wait_or_flush() and _ma_bitmap_get_page_bits()
storage/maria/ma_check.c:
Don't write extra empty line if there is no deleted blocks
Ignore START_EXTENT_BIT's in page count
Call _ma_fast_unlock_key_del() to free key_del link
storage/maria/ma_close.c:

Added variable _dbug_on_ to speed up execution when DBUG is not going to be used
Added --debug-on option to mysqld (to be able to turn of DBUG with --debug-on=0)
Fixed some bugs with 'non_flushable' marking of bitmap pages
Don't use 'non_flushable' marking of bitmap pages for not transactional tables
SHOW CREATE TABLE now shows if table was created with page checksums
Fixed a lot of bugs with BLOB handling in case of update/REDO and UNDO
More tests (especially for blobs) and DBUG_ASSERTS()
More readable output from maria_read_log and maria_chk
Fixed wrong shift that caused Maria to crash on files > 4G
Mark tables as crashed of REDO fails
dbug/dbug.c:
Changed to use my_bool (allowed me to remove some windows specific code)
Added variable _dbug_on_ to speed up execution when DBUG is not going to be used
Removed initialization of variables if not needed
include/my_dbug.h:
Use my_bool for some functions that was defined as BOOLEAN in dbug.c code

storage/maria/Makefile.am:
Added ma_test_big.sh
storage/maria/ha_maria.cc:
Store in create_info if page checksums are used (For SHOW CREATE TABLE)
storage/maria/ma_bitmap.c:
Added _ma_bitmap_wait_or_flush() to cause reader of bitmap pages to wait with reading until bitmap is flushed.
Use TAIL_PAGE_COUNT_MARKER for tail pages
Set 'sub_blocks' for and only for the head page or for the first extent of a blob. This is needed for store_extent_info() to be able to set START_EXTENT_BIT's
Don't allocate more than 0x3ffff pages in one extent (We need bit 0x4000 as a START_EXTENT_BIT)
Increase the calculated 'head_length' with the number of bytes used for extents.
Update row->space_on_head_page also in _ma_bitmap_find_new_place()
Make _ma_bitmap_get_page_bits() global. (Needed for UNDO handling)
Changed _ma_bitmap_flushable() to take MARIA_HA instead of MARIA_SHARE.
This was needed to be able to mark the handler if we had a 'non_flushable' call pending or not.
Don't use 'non_flushable' marking of bitmap pages for not transactional tables.
Added BLOCKUSED_USE_ORG_BITMAP handling also for tail pages.
Added more DBUG_ASSERT() to find possible errors in other code
Some code simplications by adding new local variables
storage/maria/ma_blockrec.c:
UNDO of rows now puts back all part of the row on their original pages and positions.
Changed UNDO of DELETE and UNDO of UPDATE to contain information about the original length of data on head block and also extent information
This changes a lot of logic as now an insert of a row on a page may happen to any position (and not just to the first or next free)
Use PAGE_COUNT to mark if an extent is the start of of a blob. (Needed for extent_to_bitmap_blocks())
Added check_directory() for checking that directroy entries are correct.
Added checking of row checksums when reading rows (with EXTRA_DEBUG)
Added make_space_for_directory() and extend_directory() for doing expansion of directory
Added get_rowpos_in_head_or_tail_page() to be able to store head/tail on original position in UNDO

Added row->min_length to hold minmum required space needed on head page
Changed find_free_position() to use make_space_for_directory()
Changed make_empty_page() to allow optional creation of directory entry
Changed delete_head_or_tail() and _ma_apply_undo_row_isnert() to not copy pagecache block (speed optimization)
Changed _ma_apply_redo_insert_row_head_or_tail() to be able to insert new row at any position on 'new' page
Changed _ma_apply_undo_row_delete() and _ma_apply_undo_row_update() to put row in it's original position
Ensure allocation of tail blocks are of at least MIN_TAIL_SIZE.
Ensure we store pages in pinned pages even if read failed. (If not we will have pages pinned forever in page cache)
Write original extent information in UNDO entry, not compacted ones (we need position to tails!)
When setting BLOCKUSED_USED, don't clear other bits (we have to preserve BLOCKUSED_USE_ORG_BITMAP)
Fixed som bugs in directory handling
Fixed bug where we wrote wrong lsn to blob pages
Added separate blob_buffer for fixing bug when updating row that had char/varchar that spanned several pages and also had blobs
Ensure we call _ma_bitmap_flushable() also in case of errors
When doing an update, first delete old entries, then search in bitmap for where to put new information
Info->s -> share
Rowid -> rowid
More DBUG_ASSERT()
storage/maria/ma_blockrec.h:
Added START_EXTENT_BIT and TAIL_PAGE_COUNT_MARKER
Added _ma_bitmap_wait_or_flush() and _ma_bitmap_get_page_bits()

Changed UNDO of DELETE and UNDO of UPDATE to contain information about the original length of data on head block and also extent information
This changes a lot of logic as now an insert of a row on a page may happen to any position (and not just to the first or next free)
Use PAGE_COUNT to mark if an extent is the start of of a blob. (Needed for extent_to_bitmap_blocks())
Added check_directory() for checking that directroy entries are correct.
Added checking of row checksums when reading rows (with EXTRA_DEBUG)
Added make_space_for_directory() and extend_directory() for doing expansion of directory
Added get_rowpos_in_head_or_tail_page() to be able to store head/tail on original position in UNDO
Added extent_to_bitmap_blocks() to be able to generate original bitmap blocks from UNDO entry
Added _ma_update_at_original_place() for UNDO of DELETES
Added row->min_length to hold minmum required space needed on head page
Changed find_free_position() to use make_space_for_directory()
Changed make_empty_page() to allow optional creation of directory entry
Changed delete_head_or_tail() and _ma_apply_undo_row_isnert() to not copy pagecache block (speed optimization)

Changed _ma_apply_undo_row_delete() and _ma_apply_undo_row_update() to put row in it's original position
Ensure allocation of tail blocks are of at least MIN_TAIL_SIZE.
Ensure we store pages in pinned pages even if read failed. (If not we will have pages pinned forever in page cache)
Write original extent information in UNDO entry, not compacted ones (we need position to tails!)
When setting BLOCKUSED_USED, don't clear other bits (we have to preserve BLOCKUSED_USE_ORG_BITMAP)
Fixed som bugs in directory handling
Fixed bug where we wrote wrong lsn to blob pages
Added separate blob_buffer for fixing bug when updating row that had char/varchar that spanned several pages and also had blobs
Ensure we call _ma_bitmap_flushable() also in case of errors
When doing an update, first delete old entries, then search in bitmap for where to put new information

Added new test by Guilhem to test if UNDO_ROW_DELETE preserves rowid
mysql-test/r/maria.result:
Added testing of page checksums
mysql-test/t/crash_commit_before-master.opt:
Added --debug-on as test require DBUG to work
mysql-test/t/maria-recovery-bitmap-master.opt:
Added --debug-on as test require DBUG to work
mysql-test/t/maria-recovery-master.opt:
Added --debug-on as test require DBUG to work
mysql-test/t/maria-recovery.test:
Added new test by Guilhem to test if UNDO_ROW_DELETE preserves rowid
mysql-test/t/maria.test:
Added testing of page checksums
sql/mysqld.cc:
Added --debug-on option (to be able to turn of DBUG with --debug-on=0)
Indentation fixes
Removed end spaces
sql/sql_show.cc:
Allow update_create_info() to inform MySQL if PACK_KEYS, NO_PACK_KEYS, CHECKSUM, PAGE_CHECKSUM or DELAY_KEY_WRITE is used
storage/maria/Makefile.am:
Added ma_test_big.sh
storage/maria/ha_maria.cc:
Store in create_info if page checksums are used (For SHOW CREATE TABLE)
storage/maria/ma_bitmap.c:
Added _ma_bitmap_wait_or_flush() to cause reader of bitmap pages to wait with reading until bitmap is flushed.
Use TAIL_PAGE_COUNT_MARKER for tail pages
Set 'sub_blocks' for and only for the head page or for the first extent of a blob. This is needed for store_extent_info() to be able to set START_EXTENT_BIT's
Don't allocate more than 0x3ffff pages in one extent (We need bit 0x4000 as a START_EXTENT_BIT)
Increase the calculated 'head_length' with the number of bytes used for extents.
Update row->space_on_head_page also in _ma_bitmap_find_new_place()
Make _ma_bitmap_get_page_bits() global. (Needed for UNDO handling)
Changed _ma_bitmap_flushable() to take MARIA_HA instead of MARIA_SHARE.
This was needed to be able to mark the handler if we had a 'non_flushable' call pending or not.
Don't use 'non_flushable' marking of bitmap pages for not transactional tables.
Added BLOCKUSED_USE_ORG_BITMAP handling also for tail pages.
Added more DBUG_ASSERT() to find possible errors in other code
Some code simplications by adding new local variables
storage/maria/ma_blockrec.c:
UNDO of rows now puts back all part of the row on their original pages and positions.
Changed UNDO of DELETE and UNDO of UPDATE to contain information about the original length of data on head block and also extent information
This changes a lot of logic as now an insert of a row on a page may happen to any position (and not just to the first or next free)
Use PAGE_COUNT to mark if an extent is the start of of a blob. (Needed for extent_to_bitmap_blocks())
Added check_directory() for checking that directroy entries are correct.
Added checking of row checksums when reading rows (with EXTRA_DEBUG)
Added make_space_for_directory() and extend_directory() for doing expansion of directory
Added get_rowpos_in_head_or_tail_page() to be able to store head/tail on original position in UNDO
Added extent_to_bitmap_blocks() to be able to generate original bitmap blocks from UNDO entry
Added _ma_update_at_original_place() for UNDO of DELETES
Added row->min_length to hold minmum required space needed on head page
Changed find_free_position() to use make_space_for_directory()
Changed make_empty_page() to allow optional creation of directory entry
Changed delete_head_or_tail() and _ma_apply_undo_row_isnert() to not copy pagecache block (speed optimization)
Changed _ma_apply_redo_insert_row_head_or_tail() to be able to insert new row at any position on 'new' page
Changed _ma_apply_undo_row_delete() and _ma_apply_undo_row_update() to put row in it's original position
Ensure allocation of tail blocks are of at least MIN_TAIL_SIZE.
Ensure we store pages in pinned pages even if read failed. (If not we will have pages pinned forever in page cache)
Write original extent information in UNDO entry, not compacted ones (we need position to tails!)
When setting BLOCKUSED_USED, don't clear other bits (we have to preserve BLOCKUSED_USE_ORG_BITMAP)
Fixed som bugs in directory handling
Fixed bug where we wrote wrong lsn to blob pages
Added separate blob_buffer for fixing bug when updating row that had char/varchar that spanned several pages and also had blobs
Ensure we call _ma_bitmap_flushable() also in case of errors
When doing an update, first delete old entries, then search in bitmap for where to put new information
Info->s -> share
Rowid -> rowid
More DBUG_ASSERT()
storage/maria/ma_blockrec.h:
Added START_EXTENT_BIT and TAIL_PAGE_COUNT_MARKER
Added _ma_bitmap_wait_or_flush() and _ma_bitmap_get_page_bits()
storage/maria/ma_check.c:
Don't write extra empty line if there is no deleted blocks
Ignore START_EXTENT_BIT's in page count
Call _ma_fast_unlock_key_del() to free key_del link
storage/maria/ma_close.c:
Ensure that used_key_del is 0. (If not, someone forgot to call _ma_unlock_key_del())
storage/maria/ma_create.c:
Changed constant to macro
storage/maria/ma_delete.c:
For deleted keys, log also position to row
storage/maria/ma_extra.c:
Release blob buffer at maria_reset() if bigger than MARIA_SMALL_BLOB_BUFFER
storage/maria/ma_key_recover.c:
Added bzero() of LSN that confused paged cache in case of uninitialized block
Mark file crashed if applying of index changes fails
Added calls to _ma_fast_unlock_key_del() for protection of shared key_del link.
storage/maria/ma_locking.c:
Added usage of MARIA_FILE_OPEN_COUNT_OFFSET
Added _ma_mark_file_crashed()
storage/maria/ma_loghandler.c:
Fixed bug where we logged uninitialized memory
storage/maria/ma_open.c:
Moved state->changed to be at start of state info on disk to allow one to easly mark files as crashed
storage/maria/ma_page.c:
Disable 'dummy' checksumming of pages as this gave false warnings.
(Need to investigate if this is ever needed)
storage/maria/ma_pagecache.c:
Fixed wrong shift that caused Maria to crash on files > 4G
storage/maria/ma_recovery.c:
In case of errors, start writing on new line if we where in %## %## printing mode (Made errors more readable)
Changed global variable name from warnings -> recovery_warnings
Use MARIA_FILE_CREATE_RENAME_LSN_OFFSET instead of constant
Removed special handling of row position for deleted keys. Keys now always includes row positions
_ma_apply_undo_row_delete() now gets page and row position
Added check that we don't loop forever when handling undo's (in case of bug in undo chain)
Print name of failed REDO/UNDO
storage/maria/ma_recovery.h:
Removed old comment
storage/maria/ma_static.c:
Chaned version number of Maria files to not accidently use old ones (becasue of change of ordering of status variables)
storage/maria/ma_test2.c:
Added option -u to specify number of rows to update
Changed old option -u to be -A, as for ma_test1
Fixed bug in update of rows with blobs (before blobs was always reset to empty on update)
First created blob is now of max blob length to ensure we have at least one big blob in the table
storage/maria/ma_test_all.sh:
More tests
storage/maria/ma_test_recovery.expected:
Updated results
storage/maria/ma_test_recovery:
Changed tests to use bigger blobs (not just 1K)
Added new tests that tests recovery of update with blobs
Removed comparision of .MAD file as it's not guranteed that recovery from scratch gives identical data file as original update
(compact_page() may be called at different times during normal execution and during REDO)
storage/maria/ma_update.c:
Simplify code (changed * to if)
storage/maria/maria_chk.c:
Make output more readable
storage/maria/maria_def.h:
Changed 'changed' to int to prepare for more bits
Added 2 more bytes to status information
Added 'st_mara_row->min_length' for storing min length needed on head page
Added 'st_mara_handler->blob_buff & blob_buff_size' for storing blobs
Moved all tunning parameters into one block
Added MARIA_SMALL_BLOB_BUFFER
Added _ma_mark_file_crashed()
storage/myisam/mi_test2.c:
Fixed bug in update of rows with blobs (before blobs was always reset to empty on update)
storage/maria/ma_test_big.sh:
Testing of insert, update, delete, recovery and undo of rows with blobs
Thanks to the random-ness of ma_test2 this is likely to find most bugs in the row handling

WL#3072 - Maria Recovery
Bulk insert: don't log REDO/UNDO for rows, log one UNDO which will
truncate files; this is an optimization and a bugfix (table was left
half-repaired by crash).
Repair: mark table crashed-on-repair at start, bump skip_redo_lsn at start,
this is easier for recovery (tells it to skip old REDOs or even UNDO
phase) and user (tells it to repair) in case of crash, sync files
in the end.
Recovery skips missing or corrupted table and moves to next record
(in REDO or UNDO phase) to be more robust; warns if happens in UNDO phase.
Bugfix for UNDO_KEY_DELETE_WITH_ROOT (tested in ma_test_recovery)
and maria_enable_indexes().
Create missing bitmaps when needed (there can be more than one to create,
in rare cases), log a record for this.
include/myisamchk.h:
new flag: bulk insert repair mustn't bump create_rename_lsn
mysql-test/lib/mtr_report.pl:
skip normal warning in maria-recovery.test
mysql-test/r/maria-recovery.result:
result: crash before bulk insert is committed, causes proper rollback,
and crash right after OPTIMIZE replaces index file with new index file
leads to table marked corrupted and recovery not failing.
mysql-test/t/maria-recovery.test:
- can't check the table or it would commit the transaction,
but check is made after recovery.
- test of crash before bulk-insert-with-repair is committed
(to see if it is rolled back), and of crash after OPTIMIZE has replaced
index file but not finished all operations (to see if recovery fails -
it used to assert when trying to execute an old REDO on the new
index).
storage/maria/CMakeLists.txt:
new file
storage/maria/Makefile.am:
new file
storage/maria/ha_maria.cc:
- If bulk insert on a transactional table using an index repair:
table is initially empty, so don't log REDO/UNDO for data rows
(optimization), just log an UNDO_BULK_INSERT_WITH_REPAIR
which will, if executed, empty the data and index file. Re-enable
logging in end_bulk_insert().
- write log record for repair operation only after it's fully done,
index sort including (maria_repair*() used to write the log record).
- Adding back file->trn=NULL which was removed by mistake earlier.
storage/maria/ha_maria.h:
new member (see ha_maria.cc)
storage/maria/ma_bitmap.c:
Functions to create missing bitmaps:
- one function which creates missing bitmaps in page cache, except
the missing one with max offset which it does not put into page cache
as it will be modified very soon.
- one function which the one above calls, and creates bitmaps in page
cache
- one function to execute REDO_BITMAP_NEW_PAGE which uses the second
one above.
storage/maria/ma_blockrec.c:
- when logging REDO_DELETE_ALL, not only 'records' and 'checksum'
has to be reset under log's mutex.
- execution of REDO_INSERT_ROW_BLOBS now checks the dirty pages' list
- execution of UNDO_BULK_INSERT_WITH_REPAIR
storage/maria/ma_blockrec.h:
new functions
storage/maria/ma_check.c:
- table-flush-before-repair is moved to a separate function reused
by maria_sort_index(); syncing is added
- maria_repair() is allowed to re-enable logging only if it is the one
which disabled it.
- "_ma_flush_table_files_after_repair" was a bad name, it's not after
repair now, and it should not sync as we do more changes to the files
shortly after (sync is postponed to when writing the log record)
- REDO_REPAIR record should be written only after all repair
operations (in particular after sorting index in ha_mara::repair())
- close to the end of repair by sort, flushing of pages must happen
also in the non-quick case, to prepare for the sync at end.
- in parallel repair, some page flushes are not needed as done
by initialize_variables_for_repair().
storage/maria/ma_create.c:
Update skip_redo_lsn, create_rename_lsn optionally.
storage/maria/ma_delete_all.c:
Need to sync files at end of maria_delete_all_rows(), if transactional.
storage/maria/ma_extra.c:
During repair, we sometimes call _ma_flush_table_files() (via
_ma_flush_table_files_before_swap()) while there is a WRITE_CACHE.
storage/maria/ma_key_recover.c:
- when we see CLR_END for UNDO_BULK_INSERT_WITH_REPAIR, re-enable
indices.
- fixing bug: _ma_apply_undo_key_delete() parsed UNDO_KEY_DELETE_WITH_ROOT
wrongly, leading to recovery failure
storage/maria/ma_key_recover.h:
new prototype
storage/maria/ma_locking.c:
DBUG_VOID_RETURN missing
storage/maria/ma_loghandler.c:
UNDO for bulk insert with repair, and REDO for creating bitmaps.
LOGREC_FIRST_FREE to not have to change the for() every time we
add a new record type.
storage/maria/ma_loghandler.h:
new UNDO and REDO
storage/maria/ma_open.c:
Move share.kfile.file=kfile up a bit, so that _ma_update_state_lsns()
can get its value, this fixes a bug where LSN_REPAIRED_BY_MARIA_CHK
was not corrected on disk by maria_open().
Store skip_redo_lsn in index' header.
maria_enable_indexes() had a bug for BLOCK_RECORD, where an empty
file has one page, not 0 bytes.
storage/maria/ma_recovery.c:
- Skip a corrupted, missing, or repaired-with-maria_chk, table in
recovery: don't fail, just go to next REDO or UNDO; but if an UNDO
is skipped in UNDO phase we issue warnings.
- Skip REDO|UNDO in REDO phase if <skip_redo_lsn.
- If UNDO phase fails, delete transactions to not make trnman
assert.
- Update skip_redo_lsn when playing REDO_CREATE_TABLE
- Don't record UNDOs for old transactions which we don't know (long_trid==0)
- Bugfix for UNDO_KEY_DELETE_WITH_ROOT (see ma_key_recover.c)
- Execution of UNDO_BULK_INSERT_WITH_REPAIR
- Don't try to find a page number in REDO_DELETE_ALL
- Pieces moved to ma_recovery_util.c
storage/maria/ma_rename.c:
name change
storage/maria/ma_static.c:
I modified layout of the index' header (inserted skip_redo_lsn in its middle)
storage/maria/ma_test2.c:
allow breaking the test towards the end, tests execution of
UNDO_KEY_DELETE_WITH_ROOT
storage/maria/ma_test_recovery.expected:
6 as testflag instead of 4
storage/maria/ma_test_recovery:
Increase the amount of rollback work to do when testing recovery
with ma_test2; this reproduces the UNDO_KEY_DELETE_WITH_ROOT bug.
storage/maria/maria_chk.c:
skip_redo_lsn should be updated too, for consistency.
Write a REDO_REPAIR after all operations (including sort-records)
have been done.
No reason to flush blocks after maria_chk_data_link() and
maria_sort_records(), there is maria_close() in the end.
write_log_record() is a function, to not clutter maria_chk().
storage/maria/maria_def.h:
New member skip_redo_lsn in the state, and comments
storage/maria/maria_pack.c:
skip_redo_lsn should be updated too, for consistency
storage/maria/ma_recovery_util.c:
_ma_redo_not_needed_for_page(), defined in ma_recovery.c, is needed
by ma_blockrec.c; this causes link issues, resolved by putting
_ma_redo_not_needed_for_page() into a new file (so that it is not
in the same file as repair-related objects of ma_recovery.c).
storage/maria/ma_recovery_util.h:

WL#3071 Maria checkpoint
Finally this is the real checkpoint code.
It however exhibits unstabilities when a checkpoint runs concurrently
with data-modifying clients (table corruption, transaction log's
assertions) so for now a checkpoint is taken only at startup after
recovery and at shutdown, i.e. not in concurrent situations. Later
we will let it run periodically, as well as flush dirty pages
periodically (almost all needed code is there already, only pagecache
code is written but not committed).
WL#3072 Maria recovery
* replacing UNDO_ROW_PURGE with CLR_END; testing of those CLR_END via
ma_test2 which has INSERTs failing with duplicate keys.
* replaying of REDO_RENAME_TABLE
Now, off to test Recovery in ha_maria :)
BitKeeper/deleted/.del-ma_least_recently_dirtied.c:
Delete: storage/maria/ma_least_recently_dirtied.c
BitKeeper/deleted/.del-ma_least_recently_dirtied.h:
Delete: storage/maria/ma_least_recently_dirtied.h
storage/maria/Makefile.am:
compile Checkpoint module
storage/maria/ha_maria.cc:
When ha_maria starts, do a recovery from last checkpoint.
Take a checkpoint when that recovery has ended and when ha_maria
shuts down cleanly.
storage/maria/ma_blockrec.c:
* even if my_sync() fails we have to my_close() (otherwise we leak
a descriptor)
* UNDO_ROW_PURGE is replaced by a simple CLR_END for UNDO_ROW_INSERT,
as promised in the old comment; it gives us skipping during the
UNDO phase.
storage/maria/ma_check.c:
All REDOs before create_rename_lsn are ignored by Recovery. So
create_rename_lsn must be set only after all data/index has been
flushed and forced to disk. We thus move write_log_record_for_repair()
to after _ma_flush_tables_files_after_repair().
storage/maria/ma_checkpoint.c:
Checkpoint module.
storage/maria/ma_checkpoint.h:
optional argument if caller wants a thread to periodically take
checkpoints and flush dirty pages.
storage/maria/ma_create.c:
* no need to init some vars as the initial bzero(share) takes care of this.
* update to new function's name
* even if we fail in my_sync() we have to my_close()
storage/maria/ma_extra.c:
Checkpoint reads share->last_version under intern_lock, so we make
maria_extra() update it under intern_lock. THR_LOCK_maria still needed
because of _ma_test_if_reopen().
storage/maria/ma_init.c:
destroy checkpoint module when Maria shuts down.
storage/maria/ma_loghandler.c:
* UNDO_ROW_PURGE gone (see ma_blockrec.c)
* we need to remember the LSN of the LOGREC_FILE_ID for a share,
because this LSN is needed into the checkpoint record (Recovery wants
to know the validity domain of an id->name mapping)
* translog_get_horizon_no_lock() needed for Checkpoint
* comment about failing assertion (Sanja knows)
* translog_init_reader_data() thought that translog_read_record_header_scan()
returns 0 in case of error, but 0 just means "0-length header".
* translog_assign_id_to_share() now needs the MARIA_HA because
LOGREC_FILE_ID uses a log-write hook.
* Verify that (de)assignment of share->id happens only under intern_lock,
as Checkpoint reads this id with intern_lock.
* translog_purge() can accept TRANSLOG_ADDRESS, not necessarily
a real LSN.
storage/maria/ma_loghandler.h:
prototype updates
storage/maria/ma_open.c:
no need to initialize "res"
storage/maria/ma_pagecache.c:
When taking a checkpoint, we don't need to know the maximum rec_lsn
of dirty pages; this LSN was intended to be used in the two-checkpoint
rule, but last_checkpoint_lsn is as good.
4 bytes for stored_list_size is enough as PAGECACHE::blocks (number
of blocks which the pagecache can contain) is int.
storage/maria/ma_pagecache.h:
new prototype
storage/maria/ma_recovery.c:
* added replaying of REDO_RENAME_TABLE
* UNDO_ROW_PURGE gone (see ma_blockrec.c), replaced by CLR_END
* Recovery from the last checkpoint record now possible
* In new_table() we skip the table if the id->name mapping is older than
create_rename_lsn (mapping dates from lsn_of_file_id).
* in get_MARIA_HA_from_REDO_record() we skip the record
if the id->name mapping is newer than the record (can happen if processing
a record which is before the checkpoint record).
* parse_checkpoint_record() has to return a LSN, that's what caller expects
storage/maria/ma_rename.c:
new function's name; log end zeroes of tables' names (ease recovery)
storage/maria/ma_test2.c:
* equivalent of ma_test1's --test-undo added (named -u here).
* -t=1 now stops right after creating the table, so that
we can test undoing of INSERTs with duplicate keys (which tests the
CLR_END logged by _ma_write_abort_block_record()).
storage/maria/ma_test_recovery.expected:
Result of testing undoing of INSERTs with duplicate keys; there are
some differences in maria_chk -dvv but they are normal (removing
records does not shrink data/index file, does not put back the
"analyzed, optimized keys"(etc) index state.
storage/maria/ma_test_recovery:
Test undoing of INSERTs with duplicate keys, using ma_test2;
when such INSERT happens, it logs REDO_INSERT, UNDO_INSERT, REDO_DELETE,
CLR_END; we abort after that, and test that CLR_END causes recovery
to jump over UNDO_INSERT.
storage/maria/ma_write.c:
comment
storage/maria/maria_chk.c:
comment
storage/maria/maria_def.h:
* a new bit in MARIA_SHARE::in_checkpoint, used to build a list
of unique shares during Checkpoint.
* MARIA_SHARE::lsn_of_file_id added: the LSN of the last LOGREC_FILE_ID
for this share; needed to know to which LSN domain the mappings
found in the Checkpoint record apply (new mappings should not apply
to old REDOs).
storage/maria/trnman.c:
* small changes to how trnman_collect_transactions() fills its buffer;
it also uses a non-dummy lsn_read_non_atomic() found in ma_checkpoint.h

WL#3071 Maria checkpoint
Finally this is the real checkpoint code.
It however exhibits unstabilities when a checkpoint runs concurrently
with data-modifying clients (table corruption, transaction log's
assertions) so for now a checkpoint is taken only at startup after
recovery and at shutdown, i.e. not in concurrent situations. Later
we will let it run periodically, as well as flush dirty pages
periodically (almost all needed code is there already, only pagecache
code is written but not committed).
WL#3072 Maria recovery
* replacing UNDO_ROW_PURGE with CLR_END; testing of those CLR_END via
ma_test2 which has INSERTs failing with duplicate keys.
* replaying of REDO_RENAME_TABLE
Now, off to test Recovery in ha_maria :)

storage/maria/ha_maria.cc:
When ha_maria starts, do a recovery from last checkpoint.
Take a checkpoint when that recovery has ended and when ha_maria
shuts down cleanly.
storage/maria/ma_blockrec.c:
* even if my_sync() fails we have to my_close() (otherwise we leak
a descriptor)
* UNDO_ROW_PURGE is replaced by a simple CLR_END for UNDO_ROW_INSERT,
as promised in the old comment; it gives us skipping during the
UNDO phase.
storage/maria/ma_check.c:
All REDOs before create_rename_lsn are ignored by Recovery. So
create_rename_lsn must be set only after all data/index has been
flushed and forced to disk. We thus move write_log_record_for_repair()
to after _ma_flush_tables_files_after_repair().

storage/maria/ma_extra.c:
Checkpoint reads share->last_version under intern_lock, so we make
maria_extra() update it under intern_lock. THR_LOCK_maria still needed
because of _ma_test_if_reopen().
storage/maria/ma_init.c:
destroy checkpoint module when Maria shuts down.
storage/maria/ma_loghandler.c:
* UNDO_ROW_PURGE gone (see ma_blockrec.c)
* we need to remember the LSN of the LOGREC_FILE_ID for a share,
because this LSN is needed into the checkpoint record (Recovery wants
to know the validity domain of an id->name mapping)
* translog_get_horizon_no_lock() needed for Checkpoint
* comment about failing assertion (Sanja knows)
* translog_init_reader_data() thought that translog_read_record_header_scan()
returns 0 in case of error, but 0 just means "0-length header".
* translog_assign_id_to_share() now needs the MARIA_HA because
LOGREC_FILE_ID uses a log-write hook.
* Verify that (de)assignment of share->id happens only under intern_lock,
as Checkpoint reads this id with intern_lock.

a real LSN.

storage/maria/ma_test2.c:

code is written but not committed).
WL#3072 Maria recovery
* replacing UNDO_ROW_PURGE with CLR_END; testing of those CLR_END via
ma_test2 which has INSERTs failing with duplicate keys.
* replaying of REDO_RENAME_TABLE
Now, off to test Recovery in ha_maria :)
BitKeeper/deleted/.del-ma_least_recently_dirtied.c:
Delete: storage/maria/ma_least_recently_dirtied.c
BitKeeper/deleted/.del-ma_least_recently_dirtied.h:
Delete: storage/maria/ma_least_recently_dirtied.h
storage/maria/Makefile.am:
compile Checkpoint module
storage/maria/ha_maria.cc:
When ha_maria starts, do a recovery from last checkpoint.
Take a checkpoint when that recovery has ended and when ha_maria
shuts down cleanly.
storage/maria/ma_blockrec.c:
* even if my_sync() fails we have to my_close() (otherwise we leak
a descriptor)
* UNDO_ROW_PURGE is replaced by a simple CLR_END for UNDO_ROW_INSERT,
as promised in the old comment; it gives us skipping during the
UNDO phase.
storage/maria/ma_check.c:
All REDOs before create_rename_lsn are ignored by Recovery. So
create_rename_lsn must be set only after all data/index has been
flushed and forced to disk. We thus move write_log_record_for_repair()
to after _ma_flush_tables_files_after_repair().
storage/maria/ma_checkpoint.c:
Checkpoint module.
storage/maria/ma_checkpoint.h:
optional argument if caller wants a thread to periodically take
checkpoints and flush dirty pages.
storage/maria/ma_create.c:
* no need to init some vars as the initial bzero(share) takes care of this.
* update to new function's name
* even if we fail in my_sync() we have to my_close()
storage/maria/ma_extra.c:
Checkpoint reads share->last_version under intern_lock, so we make
maria_extra() update it under intern_lock. THR_LOCK_maria still needed
because of _ma_test_if_reopen().
storage/maria/ma_init.c:
destroy checkpoint module when Maria shuts down.
storage/maria/ma_loghandler.c:
* UNDO_ROW_PURGE gone (see ma_blockrec.c)
* we need to remember the LSN of the LOGREC_FILE_ID for a share,
because this LSN is needed into the checkpoint record (Recovery wants
to know the validity domain of an id->name mapping)
* translog_get_horizon_no_lock() needed for Checkpoint
* comment about failing assertion (Sanja knows)
* translog_init_reader_data() thought that translog_read_record_header_scan()
returns 0 in case of error, but 0 just means "0-length header".
* translog_assign_id_to_share() now needs the MARIA_HA because
LOGREC_FILE_ID uses a log-write hook.
* Verify that (de)assignment of share->id happens only under intern_lock,
as Checkpoint reads this id with intern_lock.
* translog_purge() can accept TRANSLOG_ADDRESS, not necessarily
a real LSN.
storage/maria/ma_loghandler.h:
prototype updates
storage/maria/ma_open.c:
no need to initialize "res"
storage/maria/ma_pagecache.c:
When taking a checkpoint, we don't need to know the maximum rec_lsn
of dirty pages; this LSN was intended to be used in the two-checkpoint
rule, but last_checkpoint_lsn is as good.
4 bytes for stored_list_size is enough as PAGECACHE::blocks (number
of blocks which the pagecache can contain) is int.
storage/maria/ma_pagecache.h:
new prototype
storage/maria/ma_recovery.c:
* added replaying of REDO_RENAME_TABLE
* UNDO_ROW_PURGE gone (see ma_blockrec.c), replaced by CLR_END
* Recovery from the last checkpoint record now possible
* In new_table() we skip the table if the id->name mapping is older than
create_rename_lsn (mapping dates from lsn_of_file_id).
* in get_MARIA_HA_from_REDO_record() we skip the record
if the id->name mapping is newer than the record (can happen if processing
a record which is before the checkpoint record).
* parse_checkpoint_record() has to return a LSN, that's what caller expects
storage/maria/ma_rename.c:
new function's name; log end zeroes of tables' names (ease recovery)
storage/maria/ma_test2.c:
* equivalent of ma_test1's --test-undo added (named -u here).
* -t=1 now stops right after creating the table, so that
we can test undoing of INSERTs with duplicate keys (which tests the
CLR_END logged by _ma_write_abort_block_record()).
storage/maria/ma_test_recovery.expected:
Result of testing undoing of INSERTs with duplicate keys; there are
some differences in maria_chk -dvv but they are normal (removing
records does not shrink data/index file, does not put back the
"analyzed, optimized keys"(etc) index state.
storage/maria/ma_test_recovery:
Test undoing of INSERTs with duplicate keys, using ma_test2;
when such INSERT happens, it logs REDO_INSERT, UNDO_INSERT, REDO_DELETE,
CLR_END; we abort after that, and test that CLR_END causes recovery
to jump over UNDO_INSERT.
storage/maria/ma_write.c:
comment
storage/maria/maria_chk.c:
comment
storage/maria/maria_def.h:
* a new bit in MARIA_SHARE::in_checkpoint, used to build a list
of unique shares during Checkpoint.
* MARIA_SHARE::lsn_of_file_id added: the LSN of the last LOGREC_FILE_ID
for this share; needed to know to which LSN domain the mappings
found in the Checkpoint record apply (new mappings should not apply
to old REDOs).
storage/maria/trnman.c:
* small changes to how trnman_collect_transactions() fills its buffer;
it also uses a non-dummy lsn_read_non_atomic() found in ma_checkpoint.h

WL#3071 Maria checkpoint
Ability for flush_pagecache_blocks() to flush only certain pages of
a file, as instructed by an option "filter" pointer-to-function argument;
Checkpoint and background dirty page flushing use that to flush only
pages which have been dirty for long enough and bitmap pages.
Fix for a bug in flush_cached_blocks() (no idea if it could produce
a bug in real life, but theoretically it is).
Testing checkpoint in ma_test_recovery via ma_test1 and ma_test2.
Background checkpoint & dirty pages flush thread is still disabled
by default in ha_maria.
mysql-test/r/maria.result:
result update
storage/maria/ha_maria.cc:
blank after function comment
storage/maria/ma_checkpoint.c:
Using an enum instead of 0/1/2 (applying Sanja's review comments).
The comment about "this is an horizon" can be removed as Sanja
created translog_next_LSN() which parse_checkpoint_record() uses.
Variables in ma_checkpoint_background() cannot be declared in the
for() as their value must not be reset at each iteration!
storage/maria/ma_pagecache.c:
adding to flush_pagecache_blocks() optional arguments 'filter'
(pointer to function) and 'filter_arg'; if filter!=NULL this function
will be called for each block of the file and will reply if this
block and following ones should be flushed or not (3 possible
replies).
Fixing a bug when flush_cached_blocks() skips a pinned page: it has
to unset PCBLOCK_IN_FLUSH set by flush_pagecache_blocks_int().
storage/maria/ma_pagecache.h:
flush_pagecache_blocks() is changed to take "filter" and "filter_arg"
arguments. "filter", if it is not NULL, may return one value
among enum pagecache_flush_filter_result.
storage/maria/ma_recovery.c:
open_count=0 when closing tables at the end of recovery.
storage/maria/ma_test1.c:
Optional checkpoints (-H#) at various stages (stages similar
to --testflag), for testing of checkpoints.
storage/maria/ma_test2.c:
Optional checkpoints (-H#) at various stages (stages similar
to -t), for testing of checkpoints.
storage/maria/ma_test_recovery.expected:
Result update: the results of the additional test run with -H#
(checkpoints) are added here. They are exactly identical to without
checkpoints except that the index's Root (printed by maria_chk)
is more correct when using checkpoints. This is because checkpoint
flushed the state, so it happens to be correct, while no-checkpoint
does not flush the state, and recovery does not recover indexes
so Root is never fixed. When we recover indices, this will go away.
storage/maria/ma_test_recovery:
We duplicate the loop of tests to add an additional run with
checkpoints at various stages, to see if maria_read_log
uses them fine.

WL#3072 Maria Recovery
misc fixes of execution of UNDOs in the UNDO phase:
- into the CLR_END, store the LSN of the _previous_ UNDO (we debated
what was best, so far we're going with "previous"; later we can change
to "current" if needed), and store the type of record which is being
undone (needed to know how to update state.records when we see the
CLR_END during the REDO phase).
- declaring all UNDOs and CLR_END as "compressed"
- when executing an UNDO in the UNDO phase, state.records is updated
as a hook when writing CLR_END (needed for "recovery of the state"),
and so is trn->undo_lsn (needed for when we have checkpoints).
- bugfix (execution of UNDO_ROW_DELETE didn't store the correct checksum
into the re-inserted row, maria_chk -r thus threw the row away).
- modifications of ma_test1: where to stop is now driven by --testflag;
--test-undo just tells how to stop (flush data, flush log, nothing).
- ma_test_recovery: testing of the UNDO phase, more testing of the
REDO phase, identification of a bug.
storage/maria/ma_blockrec.c:
- bugfix: execution of UNDO_ROW_DELETE didn't store the correct
checksum into the row (leading to "maria_chk -r" eliminating the
re-inserted row, net effect was that rollback appeared to have
rolled back no deletion). Reason was that write_block_record() used
info->cur_row.checksum, while "row" can be != &info->cur_row
(case of UNDO_ROW_DELETE). After fixing this, problems with
_ma_update_block_record() appeared; indeed checksum was computed
by allocate_and_write_block_record() while _ma_update_block_record()
directly calls write_block_record(). Solution is to compute checksum
in write_block_record() instead.
- when executing an UNDO, we now pass the LSN of the _previous_ UNDO
to block_format functions. This LSN can be 0 (if the being-executed UNDO
was the transaction's first UNDO), so "undo_lsn==0" cannot work
anymore to indicate "this is not UNDO work". Using undo_lsn==LSN_ERROR
instead (this is an impossible LSN).
- store into CLR_END the type of log record which was undone
(INSERT/UPDATE/DELETE); needed for Recovery to know if/how it has
to update state.records if it sees this CLR_END in the REDO phase.
- when writing the CLR_END in _ma_apply_undo_row_insert(),
the place to store file's id is log_data+LSN_STORE_SIZE.
- in _ma_apply_undo_row_insert(), the records-- is moved
to a hook when writing the CLR_END (this way it is under log's mutex
which is needed for "recovery of the state")
storage/maria/ma_loghandler.c:
- all UNDOs, and CLR_END, start with the LSN of another UNDO; so
we can declare them "compressed".
- write_hook_for_clr_end() to set trn->undo_lsn (to the previous
UNDO's LSN) under log's lock (like UNDOs set trn->undo_lsn under log's
lock), and also update, if appropriate, state.records.
- reset share->id to 0 when deassigning; not useful for now but
sounds logical.
storage/maria/ma_recovery.c:
- if no table is found for a REDO, it's not an error; for an UNDO, it is
- in the REDO phase, when we see a CLR_END we must update trn->undo_lsn
and sometimes state.records.
- in the UNDO phase, when we execute an UNDO_ROW_INSERT:
* update trn->undo_lsn only after executing the record
* store the _previous_ undo_lsn into the CLR_END
- at the end of the REDO phase, when we recreate TRN objects, they
have already their long id in the log (either via a
LOGREC_LONG_TRANSACTION_ID, or in a checkpoint record), don't write
a new, useless LOGREC_LONG_TRANSACTION_ID for them.
storage/maria/ma_test1.c:
* where to stop execution is now driven by --testflag and not --test-undo
(ma_test2 already has --testflag for the same purpose). This allows
us to do a clean stop (with commit) at any point.
* --test-undo=# tells how to abort (flush all pages (which implies
flushing log) or only log or nothing); all such "ways of crashing"
are tested in ma_test_recovery
storage/maria/ma_test_recovery:
* Testing execution of UNDOs, with and without BLOBs.
* Testing idempotency of REDOs.
* See @todo for a probable bug with BLOBs.
* maria_chk -rq instead of -r, as with -q it nicely stops on any
problem in the data file (like the checksum bug see comment of
ma_blockrec.c).
* Testing if log was written by UNDO phase (often expected),
not written by REDO phase (always expected).
* Less output on the screen, compares with expected output in the end.
* some shell thingies like "set --" and $# are courtesy of
Danny and Pekka.
storage/maria/maria_read_log.c:
when only displaying the records, don't do an UNDO phase
storage/maria/ma_test_recovery.expected:
This is the expected output of a great part of ma_test_recovery.
ma_test_recovery compares its output to the expected output
and tells if different.
If we look at this file it mentions differences in checksum
(normal, it's not recovered yet) and in records count
(getting a correct records' count when recovery starts on an
already existing table, like when testing rollback,
is coded but not yet pushed).

- When reading rows, check if rows are visible. Give error if not
- When scanning table, ignore not visible rows
- Added function parameters to some functions, to be able to call _ma_compact_block_page() with different parameters depending of if the page is a HEAD or TAIL page
- _ma_compact_block_page() deletes transaction id's that are visible by all running transactions
- Added functions for thr_lock() to enable multiple concurrent inserts
- Added helper function 'mysql_versioning()' to enable/disable versioning
- Added helper function maria_ignore_trids(), used by maria_chk and maria_pack to see all rows.

WL#3071 Maria checkpoint
Ability for flush_pagecache_blocks() to flush only certain pages of
a file, as instructed by an option "filter" pointer-to-function argument;
Checkpoint and background dirty page flushing use that to flush only
pages which have been dirty for long enough and bitmap pages.
Fix for a bug in flush_cached_blocks() (no idea if it could produce
a bug in real life, but theoretically it is).
Testing checkpoint in ma_test_recovery via ma_test1 and ma_test2.
Background checkpoint & dirty pages flush thread is still disabled
by default in ha_maria.
mysql-test/r/maria.result:
result update
storage/maria/ha_maria.cc:
blank after function comment
storage/maria/ma_checkpoint.c:
Using an enum instead of 0/1/2 (applying Sanja's review comments).
The comment about "this is an horizon" can be removed as Sanja
created translog_next_LSN() which parse_checkpoint_record() uses.
Variables in ma_checkpoint_background() cannot be declared in the
for() as their value must not be reset at each iteration!
storage/maria/ma_pagecache.c:
adding to flush_pagecache_blocks() optional arguments 'filter'
(pointer to function) and 'filter_arg'; if filter!=NULL this function
will be called for each block of the file and will reply if this
block and following ones should be flushed or not (3 possible
replies).
Fixing a bug when flush_cached_blocks() skips a pinned page: it has
to unset PCBLOCK_IN_FLUSH set by flush_pagecache_blocks_int().
storage/maria/ma_pagecache.h:
flush_pagecache_blocks() is changed to take "filter" and "filter_arg"
arguments. "filter", if it is not NULL, may return one value
among enum pagecache_flush_filter_result.
storage/maria/ma_recovery.c:
open_count=0 when closing tables at the end of recovery.
storage/maria/ma_test1.c:
Optional checkpoints (-H#) at various stages (stages similar
to --testflag), for testing of checkpoints.
storage/maria/ma_test2.c:
Optional checkpoints (-H#) at various stages (stages similar
to -t), for testing of checkpoints.
storage/maria/ma_test_recovery.expected:
Result update: the results of the additional test run with -H#
(checkpoints) are added here. They are exactly identical to without
checkpoints except that the index's Root (printed by maria_chk)
is more correct when using checkpoints. This is because checkpoint
flushed the state, so it happens to be correct, while no-checkpoint
does not flush the state, and recovery does not recover indexes
so Root is never fixed. When we recover indices, this will go away.
storage/maria/ma_test_recovery:
We duplicate the loop of tests to add an additional run with
checkpoints at various stages, to see if maria_read_log
uses them fine.

UNDO of rows now puts back all part of the row on their original pages and positions
Added variable _dbug_on_ to speed up execution when DBUG is not going to be used
Added --debug-on option to mysqld (to be able to turn of DBUG with --debug-on=0)
Fixed some bugs with 'non_flushable' marking of bitmap pages
Don't use 'non_flushable' marking of bitmap pages for not transactional tables
SHOW CREATE TABLE now shows if table was created with page checksums
Fixed a lot of bugs with BLOB handling in case of update/REDO and UNDO
More tests (especially for blobs) and DBUG_ASSERTS()
More readable output from maria_read_log and maria_chk
Fixed wrong shift that caused Maria to crash on files > 4G
Mark tables as crashed of REDO fails
dbug/dbug.c:
Changed to use my_bool (allowed me to remove some windows specific code)
Added variable _dbug_on_ to speed up execution when DBUG is not going to be used
Removed initialization of variables if not needed
include/my_dbug.h:
Use my_bool for some functions that was defined as BOOLEAN in dbug.c code
Added DBUGGER_ON/DEBUGGER_OFF to speed up execution when DBUG is not used
include/my_global.h:
Define my_bool early
Increase MY_HOW_OFTEN_TO_WRITE as computers are now faster than 10 years ago
mysql-test/mysql-test-run.pl:
Added debug-on=0 to speed up tests
mysql-test/r/maria-recovery.result:
Added new test by Guilhem to test if UNDO_ROW_DELETE preserves rowid
mysql-test/r/maria.result:

Allow update_create_info() to inform MySQL if PACK_KEYS, NO_PACK_KEYS, CHECKSUM, PAGE_CHECKSUM or DELAY_KEY_WRITE is used
storage/maria/Makefile.am:
Added ma_test_big.sh
storage/maria/ha_maria.cc:
Store in create_info if page checksums are used (For SHOW CREATE TABLE)
storage/maria/ma_bitmap.c:
Added _ma_bitmap_wait_or_flush() to cause reader of bitmap pages to wait with reading until bitmap is flushed.
Use TAIL_PAGE_COUNT_MARKER for tail pages
Set 'sub_blocks' for and only for the head page or for the first extent of a blob. This is needed for store_extent_info() to be able to set START_EXTENT_BIT's
Don't allocate more than 0x3ffff pages in one extent (We need bit 0x4000 as a START_EXTENT_BIT)
Increase the calculated 'head_length' with the number of bytes used for extents.
Update row->space_on_head_page also in _ma_bitmap_find_new_place()
Make _ma_bitmap_get_page_bits() global. (Needed for UNDO handling)
Changed _ma_bitmap_flushable() to take MARIA_HA instead of MARIA_SHARE.
This was needed to be able to mark the handler if we had a 'non_flushable' call pending or not.
Don't use 'non_flushable' marking of bitmap pages for not transactional tables.
Added BLOCKUSED_USE_ORG_BITMAP handling also for tail pages.
Added more DBUG_ASSERT() to find possible errors in other code
Some code simplications by adding new local variables
storage/maria/ma_blockrec.c:
UNDO of rows now puts back all part of the row on their original pages and positions.
Changed UNDO of DELETE and UNDO of UPDATE to contain information about the original length of data on head block and also extent information
This changes a lot of logic as now an insert of a row on a page may happen to any position (and not just to the first or next free)
Use PAGE_COUNT to mark if an extent is the start of of a blob. (Needed for extent_to_bitmap_blocks())
Added check_directory() for checking that directroy entries are correct.
Added checking of row checksums when reading rows (with EXTRA_DEBUG)
Added make_space_for_directory() and extend_directory() for doing expansion of directory
Added get_rowpos_in_head_or_tail_page() to be able to store head/tail on original position in UNDO

Added _ma_update_at_original_place() for UNDO of DELETES
Added row->min_length to hold minmum required space needed on head page
Changed find_free_position() to use make_space_for_directory()
Changed make_empty_page() to allow optional creation of directory entry
Changed delete_head_or_tail() and _ma_apply_undo_row_isnert() to not copy pagecache block (speed optimization)
Changed _ma_apply_redo_insert_row_head_or_tail() to be able to insert new row at any position on 'new' page
Changed _ma_apply_undo_row_delete() and _ma_apply_undo_row_update() to put row in it's original position
Ensure allocation of tail blocks are of at least MIN_TAIL_SIZE.
Ensure we store pages in pinned pages even if read failed. (If not we will have pages pinned forever in page cache)
Write original extent information in UNDO entry, not compacted ones (we need position to tails!)
When setting BLOCKUSED_USED, don't clear other bits (we have to preserve BLOCKUSED_USE_ORG_BITMAP)
Fixed som bugs in directory handling
Fixed bug where we wrote wrong lsn to blob pages
Added separate blob_buffer for fixing bug when updating row that had char/varchar that spanned several pages and also had blobs
Ensure we call _ma_bitmap_flushable() also in case of errors
When doing an update, first delete old entries, then search in bitmap for where to put new information
Info->s -> share
Rowid -> rowid
More DBUG_ASSERT()
storage/maria/ma_blockrec.h:
Added START_EXTENT_BIT and TAIL_PAGE_COUNT_MARKER
Added _ma_bitmap_wait_or_flush() and _ma_bitmap_get_page_bits()
storage/maria/ma_check.c:
Don't write extra empty line if there is no deleted blocks
Ignore START_EXTENT_BIT's in page count
Call _ma_fast_unlock_key_del() to free key_del link
storage/maria/ma_close.c:
Ensure that used_key_del is 0. (If not, someone forgot to call _ma_unlock_key_del())
storage/maria/ma_create.c:
Changed constant to macro
storage/maria/ma_delete.c:
For deleted keys, log also position to row
storage/maria/ma_extra.c:
Release blob buffer at maria_reset() if bigger than MARIA_SMALL_BLOB_BUFFER
storage/maria/ma_key_recover.c:
Added bzero() of LSN that confused paged cache in case of uninitialized block
Mark file crashed if applying of index changes fails
Added calls to _ma_fast_unlock_key_del() for protection of shared key_del link.
storage/maria/ma_locking.c:
Added usage of MARIA_FILE_OPEN_COUNT_OFFSET
Added _ma_mark_file_crashed()
storage/maria/ma_loghandler.c:
Fixed bug where we logged uninitialized memory
storage/maria/ma_open.c:
Moved state->changed to be at start of state info on disk to allow one to easly mark files as crashed
storage/maria/ma_page.c:
Disable 'dummy' checksumming of pages as this gave false warnings.
(Need to investigate if this is ever needed)
storage/maria/ma_pagecache.c:
Fixed wrong shift that caused Maria to crash on files > 4G
storage/maria/ma_recovery.c:
In case of errors, start writing on new line if we where in %## %## printing mode (Made errors more readable)
Changed global variable name from warnings -> recovery_warnings
Use MARIA_FILE_CREATE_RENAME_LSN_OFFSET instead of constant
Removed special handling of row position for deleted keys. Keys now always includes row positions
_ma_apply_undo_row_delete() now gets page and row position
Added check that we don't loop forever when handling undo's (in case of bug in undo chain)
Print name of failed REDO/UNDO
storage/maria/ma_recovery.h:
Removed old comment
storage/maria/ma_static.c:
Chaned version number of Maria files to not accidently use old ones (becasue of change of ordering of status variables)
storage/maria/ma_test2.c:
Added option -u to specify number of rows to update
Changed old option -u to be -A, as for ma_test1
Fixed bug in update of rows with blobs (before blobs was always reset to empty on update)
First created blob is now of max blob length to ensure we have at least one big blob in the table
storage/maria/ma_test_all.sh:
More tests
storage/maria/ma_test_recovery.expected:
Updated results
storage/maria/ma_test_recovery:
Changed tests to use bigger blobs (not just 1K)
Added new tests that tests recovery of update with blobs
Removed comparision of .MAD file as it's not guranteed that recovery from scratch gives identical data file as original update
(compact_page() may be called at different times during normal execution and during REDO)
storage/maria/ma_update.c:
Simplify code (changed * to if)
storage/maria/maria_chk.c:
Make output more readable
storage/maria/maria_def.h:
Changed 'changed' to int to prepare for more bits
Added 2 more bytes to status information
Added 'st_mara_row->min_length' for storing min length needed on head page

Fixed bug in update of rows with blobs (before blobs was always reset to empty on update)
storage/maria/ma_test_big.sh:
Testing of insert, update, delete, recovery and undo of rows with blobs
Thanks to the random-ness of ma_test2 this is likely to find most bugs in the row handling

Don't allocate more than 0x3ffff pages in one extent (We need bit 0x4000 as a START_EXTENT_BIT)
Increase the calculated 'head_length' with the number of bytes used for extents.
Update row->space_on_head_page also in _ma_bitmap_find_new_place()
Make _ma_bitmap_get_page_bits() global. (Needed for UNDO handling)
Changed _ma_bitmap_flushable() to take MARIA_HA instead of MARIA_SHARE.
This was needed to be able to mark the handler if we had a 'non_flushable' call pending or not.
Don't use 'non_flushable' marking of bitmap pages for not transactional tables.
Added BLOCKUSED_USE_ORG_BITMAP handling also for tail pages.
Added more DBUG_ASSERT() to find possible errors in other code
Some code simplications by adding new local variables
storage/maria/ma_blockrec.c:
UNDO of rows now puts back all part of the row on their original pages and positions.
Changed UNDO of DELETE and UNDO of UPDATE to contain information about the original length of data on head block and also extent information
This changes a lot of logic as now an insert of a row on a page may happen to any position (and not just to the first or next free)
Use PAGE_COUNT to mark if an extent is the start of of a blob. (Needed for extent_to_bitmap_blocks())
Added check_directory() for checking that directroy entries are correct.
Added checking of row checksums when reading rows (with EXTRA_DEBUG)
Added make_space_for_directory() and extend_directory() for doing expansion of directory
Added get_rowpos_in_head_or_tail_page() to be able to store head/tail on original position in UNDO
Added extent_to_bitmap_blocks() to be able to generate original bitmap blocks from UNDO entry
Added _ma_update_at_original_place() for UNDO of DELETES
Added row->min_length to hold minmum required space needed on head page
Changed find_free_position() to use make_space_for_directory()
Changed make_empty_page() to allow optional creation of directory entry
Changed delete_head_or_tail() and _ma_apply_undo_row_isnert() to not copy pagecache block (speed optimization)
Changed _ma_apply_redo_insert_row_head_or_tail() to be able to insert new row at any position on 'new' page
Changed _ma_apply_undo_row_delete() and _ma_apply_undo_row_update() to put row in it's original position
Ensure allocation of tail blocks are of at least MIN_TAIL_SIZE.
Ensure we store pages in pinned pages even if read failed. (If not we will have pages pinned forever in page cache)
Write original extent information in UNDO entry, not compacted ones (we need position to tails!)
When setting BLOCKUSED_USED, don't clear other bits (we have to preserve BLOCKUSED_USE_ORG_BITMAP)
Fixed som bugs in directory handling
Fixed bug where we wrote wrong lsn to blob pages
Added separate blob_buffer for fixing bug when updating row that had char/varchar that spanned several pages and also had blobs
Ensure we call _ma_bitmap_flushable() also in case of errors
When doing an update, first delete old entries, then search in bitmap for where to put new information
Info->s -> share
Rowid -> rowid
More DBUG_ASSERT()

Use MARIA_FILE_CREATE_RENAME_LSN_OFFSET instead of constant
Removed special handling of row position for deleted keys. Keys now always includes row positions
_ma_apply_undo_row_delete() now gets page and row position
Added check that we don't loop forever when handling undo's (in case of bug in undo chain)
Print name of failed REDO/UNDO
storage/maria/ma_recovery.h:

storage/maria/ma_static.c:
Chaned version number of Maria files to not accidently use old ones (becasue of change of ordering of status variables)

Use PAGE_COUNT to mark if an extent is the start of of a blob. (Needed for extent_to_bitmap_blocks())
Added check_directory() for checking that directroy entries are correct.
Added checking of row checksums when reading rows (with EXTRA_DEBUG)
Added make_space_for_directory() and extend_directory() for doing expansion of directory

Changed _ma_apply_undo_row_delete() and _ma_apply_undo_row_update() to put row in it's original position
Ensure allocation of tail blocks are of at least MIN_TAIL_SIZE.
Ensure we store pages in pinned pages even if read failed. (If not we will have pages pinned forever in page cache)
Write original extent information in UNDO entry, not compacted ones (we need position to tails!)
When setting BLOCKUSED_USED, don't clear other bits (we have to preserve BLOCKUSED_USE_ORG_BITMAP)
Fixed som bugs in directory handling
Fixed bug where we wrote wrong lsn to blob pages
Added separate blob_buffer for fixing bug when updating row that had char/varchar that spanned several pages and also had blobs
Ensure we call _ma_bitmap_flushable() also in case of errors
When doing an update, first delete old entries, then search in bitmap for where to put new information
Info->s -> share
Rowid -> rowid
More DBUG_ASSERT()
storage/maria/ma_blockrec.h:
Added START_EXTENT_BIT and TAIL_PAGE_COUNT_MARKER
Added _ma_bitmap_wait_or_flush() and _ma_bitmap_get_page_bits()

Fixed bug where we logged uninitialized memory
storage/maria/ma_open.c:
Moved state->changed to be at start of state info on disk to allow one to easly mark files as crashed
storage/maria/ma_page.c:
Disable 'dummy' checksumming of pages as this gave false warnings.
(Need to investigate if this is ever needed)
storage/maria/ma_pagecache.c:
Fixed wrong shift that caused Maria to crash on files > 4G
storage/maria/ma_recovery.c:
In case of errors, start writing on new line if we where in %## %## printing mode (Made errors more readable)
Changed global variable name from warnings -> recovery_warnings
Use MARIA_FILE_CREATE_RENAME_LSN_OFFSET instead of constant
Removed special handling of row position for deleted keys. Keys now always includes row positions
_ma_apply_undo_row_delete() now gets page and row position
Added check that we don't loop forever when handling undo's (in case of bug in undo chain)
Print name of failed REDO/UNDO
storage/maria/ma_recovery.h:
Removed old comment
storage/maria/ma_static.c:
Chaned version number of Maria files to not accidently use old ones (becasue of change of ordering of status variables)
storage/maria/ma_test2.c:
Added option -u to specify number of rows to update
Changed old option -u to be -A, as for ma_test1
Fixed bug in update of rows with blobs (before blobs was always reset to empty on update)
First created blob is now of max blob length to ensure we have at least one big blob in the table
storage/maria/ma_test_all.sh:
More tests
storage/maria/ma_test_recovery.expected:
Updated results
storage/maria/ma_test_recovery:
Changed tests to use bigger blobs (not just 1K)
Added new tests that tests recovery of update with blobs
Removed comparision of .MAD file as it's not guranteed that recovery from scratch gives identical data file as original update
(compact_page() may be called at different times during normal execution and during REDO)
storage/maria/ma_update.c:
Simplify code (changed * to if)
storage/maria/maria_chk.c:
Make output more readable

Changed old option -u to be -A, as for ma_test1
Fixed bug in update of rows with blobs (before blobs was always reset to empty on update)
First created blob is now of max blob length to ensure we have at least one big blob in the table
storage/maria/ma_test_all.sh:
More tests
storage/maria/ma_test_recovery.expected:
Updated results
storage/maria/ma_test_recovery:
Changed tests to use bigger blobs (not just 1K)
Added new tests that tests recovery of update with blobs
Removed comparision of .MAD file as it's not guranteed that recovery from scratch gives identical data file as original update
(compact_page() may be called at different times during normal execution and during REDO)
storage/maria/ma_update.c:
Simplify code (changed * to if)
storage/maria/maria_chk.c:
Make output more readable
storage/maria/maria_def.h:
Changed 'changed' to int to prepare for more bits
Added 2 more bytes to status information
Added 'st_mara_row->min_length' for storing min length needed on head page
Added 'st_mara_handler->blob_buff & blob_buff_size' for storing blobs
Moved all tunning parameters into one block
Added MARIA_SMALL_BLOB_BUFFER
Added _ma_mark_file_crashed()
storage/myisam/mi_test2.c:
Fixed bug in update of rows with blobs (before blobs was always reset to empty on update)
storage/maria/ma_test_big.sh:
Testing of insert, update, delete, recovery and undo of rows with blobs
Thanks to the random-ness of ma_test2 this is likely to find most bugs in the row handling

WL#3072 - Maria Recovery
Bulk insert: don't log REDO/UNDO for rows, log one UNDO which will
truncate files; this is an optimization and a bugfix (table was left
half-repaired by crash).
Repair: mark table crashed-on-repair at start, bump skip_redo_lsn at start,
this is easier for recovery (tells it to skip old REDOs or even UNDO
phase) and user (tells it to repair) in case of crash, sync files
in the end.
Recovery skips missing or corrupted table and moves to next record
(in REDO or UNDO phase) to be more robust; warns if happens in UNDO phase.
Bugfix for UNDO_KEY_DELETE_WITH_ROOT (tested in ma_test_recovery)
and maria_enable_indexes().
Create missing bitmaps when needed (there can be more than one to create,
in rare cases), log a record for this.
include/myisamchk.h:
new flag: bulk insert repair mustn't bump create_rename_lsn
mysql-test/lib/mtr_report.pl:
skip normal warning in maria-recovery.test
mysql-test/r/maria-recovery.result:
result: crash before bulk insert is committed, causes proper rollback,
and crash right after OPTIMIZE replaces index file with new index file
leads to table marked corrupted and recovery not failing.
mysql-test/t/maria-recovery.test:
- can't check the table or it would commit the transaction,
but check is made after recovery.
- test of crash before bulk-insert-with-repair is committed
(to see if it is rolled back), and of crash after OPTIMIZE has replaced
index file but not finished all operations (to see if recovery fails -
it used to assert when trying to execute an old REDO on the new
index).
storage/maria/CMakeLists.txt:
new file
storage/maria/Makefile.am:
new file
storage/maria/ha_maria.cc:
- If bulk insert on a transactional table using an index repair:
table is initially empty, so don't log REDO/UNDO for data rows
(optimization), just log an UNDO_BULK_INSERT_WITH_REPAIR
which will, if executed, empty the data and index file. Re-enable
logging in end_bulk_insert().
- write log record for repair operation only after it's fully done,
index sort including (maria_repair*() used to write the log record).
- Adding back file->trn=NULL which was removed by mistake earlier.
storage/maria/ha_maria.h:
new member (see ha_maria.cc)
storage/maria/ma_bitmap.c:
Functions to create missing bitmaps:
- one function which creates missing bitmaps in page cache, except
the missing one with max offset which it does not put into page cache
as it will be modified very soon.
- one function which the one above calls, and creates bitmaps in page
cache
- one function to execute REDO_BITMAP_NEW_PAGE which uses the second
one above.
storage/maria/ma_blockrec.c:
- when logging REDO_DELETE_ALL, not only 'records' and 'checksum'
has to be reset under log's mutex.
- execution of REDO_INSERT_ROW_BLOBS now checks the dirty pages' list
- execution of UNDO_BULK_INSERT_WITH_REPAIR
storage/maria/ma_blockrec.h:
new functions
storage/maria/ma_check.c:
- table-flush-before-repair is moved to a separate function reused
by maria_sort_index(); syncing is added
- maria_repair() is allowed to re-enable logging only if it is the one
which disabled it.
- "_ma_flush_table_files_after_repair" was a bad name, it's not after
repair now, and it should not sync as we do more changes to the files
shortly after (sync is postponed to when writing the log record)
- REDO_REPAIR record should be written only after all repair
operations (in particular after sorting index in ha_mara::repair())
- close to the end of repair by sort, flushing of pages must happen
also in the non-quick case, to prepare for the sync at end.
- in parallel repair, some page flushes are not needed as done
by initialize_variables_for_repair().
storage/maria/ma_create.c:
Update skip_redo_lsn, create_rename_lsn optionally.
storage/maria/ma_delete_all.c:
Need to sync files at end of maria_delete_all_rows(), if transactional.
storage/maria/ma_extra.c:
During repair, we sometimes call _ma_flush_table_files() (via
_ma_flush_table_files_before_swap()) while there is a WRITE_CACHE.
storage/maria/ma_key_recover.c:
- when we see CLR_END for UNDO_BULK_INSERT_WITH_REPAIR, re-enable
indices.
- fixing bug: _ma_apply_undo_key_delete() parsed UNDO_KEY_DELETE_WITH_ROOT
wrongly, leading to recovery failure
storage/maria/ma_key_recover.h:
new prototype
storage/maria/ma_locking.c:
DBUG_VOID_RETURN missing
storage/maria/ma_loghandler.c:
UNDO for bulk insert with repair, and REDO for creating bitmaps.
LOGREC_FIRST_FREE to not have to change the for() every time we
add a new record type.
storage/maria/ma_loghandler.h:
new UNDO and REDO
storage/maria/ma_open.c:
Move share.kfile.file=kfile up a bit, so that _ma_update_state_lsns()
can get its value, this fixes a bug where LSN_REPAIRED_BY_MARIA_CHK
was not corrected on disk by maria_open().
Store skip_redo_lsn in index' header.
maria_enable_indexes() had a bug for BLOCK_RECORD, where an empty
file has one page, not 0 bytes.
storage/maria/ma_recovery.c:
- Skip a corrupted, missing, or repaired-with-maria_chk, table in
recovery: don't fail, just go to next REDO or UNDO; but if an UNDO
is skipped in UNDO phase we issue warnings.
- Skip REDO|UNDO in REDO phase if <skip_redo_lsn.
- If UNDO phase fails, delete transactions to not make trnman
assert.
- Update skip_redo_lsn when playing REDO_CREATE_TABLE
- Don't record UNDOs for old transactions which we don't know (long_trid==0)
- Bugfix for UNDO_KEY_DELETE_WITH_ROOT (see ma_key_recover.c)
- Execution of UNDO_BULK_INSERT_WITH_REPAIR
- Don't try to find a page number in REDO_DELETE_ALL
- Pieces moved to ma_recovery_util.c
storage/maria/ma_rename.c:
name change
storage/maria/ma_static.c:
I modified layout of the index' header (inserted skip_redo_lsn in its middle)
storage/maria/ma_test2.c:
allow breaking the test towards the end, tests execution of
UNDO_KEY_DELETE_WITH_ROOT
storage/maria/ma_test_recovery.expected:
6 as testflag instead of 4
storage/maria/ma_test_recovery:
Increase the amount of rollback work to do when testing recovery
with ma_test2; this reproduces the UNDO_KEY_DELETE_WITH_ROOT bug.
storage/maria/maria_chk.c:
skip_redo_lsn should be updated too, for consistency.
Write a REDO_REPAIR after all operations (including sort-records)
have been done.
No reason to flush blocks after maria_chk_data_link() and
maria_sort_records(), there is maria_close() in the end.
write_log_record() is a function, to not clutter maria_chk().
storage/maria/maria_def.h:
New member skip_redo_lsn in the state, and comments
storage/maria/maria_pack.c:
skip_redo_lsn should be updated too, for consistency
storage/maria/ma_recovery_util.c:
_ma_redo_not_needed_for_page(), defined in ma_recovery.c, is needed
by ma_blockrec.c; this causes link issues, resolved by putting
_ma_redo_not_needed_for_page() into a new file (so that it is not
in the same file as repair-related objects of ma_recovery.c).
storage/maria/ma_recovery_util.h:

WL#3071 Maria checkpoint
Finally this is the real checkpoint code.
It however exhibits unstabilities when a checkpoint runs concurrently
with data-modifying clients (table corruption, transaction log's
assertions) so for now a checkpoint is taken only at startup after
recovery and at shutdown, i.e. not in concurrent situations. Later
we will let it run periodically, as well as flush dirty pages
periodically (almost all needed code is there already, only pagecache
code is written but not committed).
WL#3072 Maria recovery
* replacing UNDO_ROW_PURGE with CLR_END; testing of those CLR_END via
ma_test2 which has INSERTs failing with duplicate keys.
* replaying of REDO_RENAME_TABLE
Now, off to test Recovery in ha_maria :)

storage/maria/Makefile.am:
compile Checkpoint module
storage/maria/ha_maria.cc:
When ha_maria starts, do a recovery from last checkpoint.
Take a checkpoint when that recovery has ended and when ha_maria
shuts down cleanly.
storage/maria/ma_blockrec.c:
* even if my_sync() fails we have to my_close() (otherwise we leak
a descriptor)
* UNDO_ROW_PURGE is replaced by a simple CLR_END for UNDO_ROW_INSERT,
as promised in the old comment; it gives us skipping during the
UNDO phase.
storage/maria/ma_check.c:
All REDOs before create_rename_lsn are ignored by Recovery. So
create_rename_lsn must be set only after all data/index has been
flushed and forced to disk. We thus move write_log_record_for_repair()
to after _ma_flush_tables_files_after_repair().
storage/maria/ma_checkpoint.c:
Checkpoint module.
storage/maria/ma_checkpoint.h:
optional argument if caller wants a thread to periodically take
checkpoints and flush dirty pages.
storage/maria/ma_create.c:
* no need to init some vars as the initial bzero(share) takes care of this.
* update to new function's name
* even if we fail in my_sync() we have to my_close()
storage/maria/ma_extra.c:
Checkpoint reads share->last_version under intern_lock, so we make
maria_extra() update it under intern_lock. THR_LOCK_maria still needed
because of _ma_test_if_reopen().
storage/maria/ma_init.c:
destroy checkpoint module when Maria shuts down.
storage/maria/ma_loghandler.c:
* UNDO_ROW_PURGE gone (see ma_blockrec.c)
* we need to remember the LSN of the LOGREC_FILE_ID for a share,
because this LSN is needed into the checkpoint record (Recovery wants
to know the validity domain of an id->name mapping)
* translog_get_horizon_no_lock() needed for Checkpoint
* comment about failing assertion (Sanja knows)
* translog_init_reader_data() thought that translog_read_record_header_scan()
returns 0 in case of error, but 0 just means "0-length header".
* translog_assign_id_to_share() now needs the MARIA_HA because
LOGREC_FILE_ID uses a log-write hook.
* Verify that (de)assignment of share->id happens only under intern_lock,
as Checkpoint reads this id with intern_lock.
* translog_purge() can accept TRANSLOG_ADDRESS, not necessarily
a real LSN.
storage/maria/ma_loghandler.h:
prototype updates
storage/maria/ma_open.c:
no need to initialize "res"
storage/maria/ma_pagecache.c:
When taking a checkpoint, we don't need to know the maximum rec_lsn
of dirty pages; this LSN was intended to be used in the two-checkpoint
rule, but last_checkpoint_lsn is as good.
4 bytes for stored_list_size is enough as PAGECACHE::blocks (number
of blocks which the pagecache can contain) is int.
storage/maria/ma_pagecache.h:
new prototype
storage/maria/ma_recovery.c:
* added replaying of REDO_RENAME_TABLE
* UNDO_ROW_PURGE gone (see ma_blockrec.c), replaced by CLR_END
* Recovery from the last checkpoint record now possible
* In new_table() we skip the table if the id->name mapping is older than
create_rename_lsn (mapping dates from lsn_of_file_id).
* in get_MARIA_HA_from_REDO_record() we skip the record
if the id->name mapping is newer than the record (can happen if processing
a record which is before the checkpoint record).
* parse_checkpoint_record() has to return a LSN, that's what caller expects
storage/maria/ma_rename.c:
new function's name; log end zeroes of tables' names (ease recovery)
storage/maria/ma_test2.c:
* equivalent of ma_test1's --test-undo added (named -u here).
* -t=1 now stops right after creating the table, so that
we can test undoing of INSERTs with duplicate keys (which tests the
CLR_END logged by _ma_write_abort_block_record()).
storage/maria/ma_test_recovery.expected:
Result of testing undoing of INSERTs with duplicate keys; there are
some differences in maria_chk -dvv but they are normal (removing
records does not shrink data/index file, does not put back the
"analyzed, optimized keys"(etc) index state.
storage/maria/ma_test_recovery:
Test undoing of INSERTs with duplicate keys, using ma_test2;
when such INSERT happens, it logs REDO_INSERT, UNDO_INSERT, REDO_DELETE,
CLR_END; we abort after that, and test that CLR_END causes recovery
to jump over UNDO_INSERT.
storage/maria/ma_write.c:
comment
storage/maria/maria_chk.c:
comment
storage/maria/maria_def.h:
* a new bit in MARIA_SHARE::in_checkpoint, used to build a list
of unique shares during Checkpoint.
* MARIA_SHARE::lsn_of_file_id added: the LSN of the last LOGREC_FILE_ID
for this share; needed to know to which LSN domain the mappings
found in the Checkpoint record apply (new mappings should not apply
to old REDOs).
storage/maria/trnman.c:
* small changes to how trnman_collect_transactions() fills its buffer;
it also uses a non-dummy lsn_read_non_atomic() found in ma_checkpoint.h

WL#3071 Maria checkpoint
Finally this is the real checkpoint code.
It however exhibits unstabilities when a checkpoint runs concurrently
with data-modifying clients (table corruption, transaction log's
assertions) so for now a checkpoint is taken only at startup after
recovery and at shutdown, i.e. not in concurrent situations. Later
we will let it run periodically, as well as flush dirty pages
periodically (almost all needed code is there already, only pagecache
code is written but not committed).
WL#3072 Maria recovery
* replacing UNDO_ROW_PURGE with CLR_END; testing of those CLR_END via
ma_test2 which has INSERTs failing with duplicate keys.
* replaying of REDO_RENAME_TABLE
Now, off to test Recovery in ha_maria :)

storage/maria/ha_maria.cc:
When ha_maria starts, do a recovery from last checkpoint.
Take a checkpoint when that recovery has ended and when ha_maria
shuts down cleanly.
storage/maria/ma_blockrec.c:
* even if my_sync() fails we have to my_close() (otherwise we leak
a descriptor)
* UNDO_ROW_PURGE is replaced by a simple CLR_END for UNDO_ROW_INSERT,
as promised in the old comment; it gives us skipping during the
UNDO phase.
storage/maria/ma_check.c:
All REDOs before create_rename_lsn are ignored by Recovery. So
create_rename_lsn must be set only after all data/index has been
flushed and forced to disk. We thus move write_log_record_for_repair()
to after _ma_flush_tables_files_after_repair().

maria_extra() update it under intern_lock. THR_LOCK_maria still needed
because of _ma_test_if_reopen().
storage/maria/ma_init.c:
destroy checkpoint module when Maria shuts down.
storage/maria/ma_loghandler.c:
* UNDO_ROW_PURGE gone (see ma_blockrec.c)
* we need to remember the LSN of the LOGREC_FILE_ID for a share,
because this LSN is needed into the checkpoint record (Recovery wants
to know the validity domain of an id->name mapping)
* translog_get_horizon_no_lock() needed for Checkpoint
* comment about failing assertion (Sanja knows)
* translog_init_reader_data() thought that translog_read_record_header_scan()
returns 0 in case of error, but 0 just means "0-length header".
* translog_assign_id_to_share() now needs the MARIA_HA because
LOGREC_FILE_ID uses a log-write hook.
* Verify that (de)assignment of share->id happens only under intern_lock,
as Checkpoint reads this id with intern_lock.
* translog_purge() can accept TRANSLOG_ADDRESS, not necessarily
a real LSN.

storage/maria/ma_pagecache.c:

* in get_MARIA_HA_from_REDO_record() we skip the record
if the id->name mapping is newer than the record (can happen if processing
a record which is before the checkpoint record).
* parse_checkpoint_record() has to return a LSN, that's what caller expects
storage/maria/ma_rename.c:
new function's name; log end zeroes of tables' names (ease recovery)
storage/maria/ma_test2.c:

* -t=1 now stops right after creating the table, so that
we can test undoing of INSERTs with duplicate keys (which tests the
CLR_END logged by _ma_write_abort_block_record()).

WL#3071 Maria checkpoint
Ability for flush_pagecache_blocks() to flush only certain pages of
a file, as instructed by an option "filter" pointer-to-function argument;
Checkpoint and background dirty page flushing use that to flush only
pages which have been dirty for long enough and bitmap pages.
Fix for a bug in flush_cached_blocks() (no idea if it could produce
a bug in real life, but theoretically it is).
Testing checkpoint in ma_test_recovery via ma_test1 and ma_test2.
Background checkpoint & dirty pages flush thread is still disabled
by default in ha_maria.

Using an enum instead of 0/1/2 (applying Sanja's review comments).
The comment about "this is an horizon" can be removed as Sanja
created translog_next_LSN() which parse_checkpoint_record() uses.
Variables in ma_checkpoint_background() cannot be declared in the
for() as their value must not be reset at each iteration!
storage/maria/ma_pagecache.c:
adding to flush_pagecache_blocks() optional arguments 'filter'
(pointer to function) and 'filter_arg'; if filter!=NULL this function
will be called for each block of the file and will reply if this
block and following ones should be flushed or not (3 possible
replies).
Fixing a bug when flush_cached_blocks() skips a pinned page: it has
to unset PCBLOCK_IN_FLUSH set by flush_pagecache_blocks_int().
storage/maria/ma_pagecache.h:
flush_pagecache_blocks() is changed to take "filter" and "filter_arg"
arguments. "filter", if it is not NULL, may return one value
among enum pagecache_flush_filter_result.
storage/maria/ma_recovery.c:
open_count=0 when closing tables at the end of recovery.
storage/maria/ma_test1.c:
Optional checkpoints (-H#) at various stages (stages similar
to --testflag), for testing of checkpoints.
storage/maria/ma_test2.c:
Optional checkpoints (-H#) at various stages (stages similar
to -t), for testing of checkpoints.
storage/maria/ma_test_recovery.expected:
Result update: the results of the additional test run with -H#
(checkpoints) are added here. They are exactly identical to without
checkpoints except that the index's Root (printed by maria_chk)
is more correct when using checkpoints. This is because checkpoint
flushed the state, so it happens to be correct, while no-checkpoint
does not flush the state, and recovery does not recover indexes
so Root is never fixed. When we recover indices, this will go away.
storage/maria/ma_test_recovery:
We duplicate the loop of tests to add an additional run with
checkpoints at various stages, to see if maria_read_log
uses them fine.

WL#3072 Maria Recovery
misc fixes of execution of UNDOs in the UNDO phase:
- into the CLR_END, store the LSN of the _previous_ UNDO (we debated
what was best, so far we're going with "previous"; later we can change
to "current" if needed), and store the type of record which is being
undone (needed to know how to update state.records when we see the
CLR_END during the REDO phase).
- declaring all UNDOs and CLR_END as "compressed"
- when executing an UNDO in the UNDO phase, state.records is updated
as a hook when writing CLR_END (needed for "recovery of the state"),
and so is trn->undo_lsn (needed for when we have checkpoints).
- bugfix (execution of UNDO_ROW_DELETE didn't store the correct checksum
into the re-inserted row, maria_chk -r thus threw the row away).
- modifications of ma_test1: where to stop is now driven by --testflag;
--test-undo just tells how to stop (flush data, flush log, nothing).
- ma_test_recovery: testing of the UNDO phase, more testing of the
REDO phase, identification of a bug.
storage/maria/ma_blockrec.c:
- bugfix: execution of UNDO_ROW_DELETE didn't store the correct
checksum into the row (leading to "maria_chk -r" eliminating the
re-inserted row, net effect was that rollback appeared to have
rolled back no deletion). Reason was that write_block_record() used
info->cur_row.checksum, while "row" can be != &info->cur_row
(case of UNDO_ROW_DELETE). After fixing this, problems with
_ma_update_block_record() appeared; indeed checksum was computed
by allocate_and_write_block_record() while _ma_update_block_record()
directly calls write_block_record(). Solution is to compute checksum
in write_block_record() instead.
- when executing an UNDO, we now pass the LSN of the _previous_ UNDO
to block_format functions. This LSN can be 0 (if the being-executed UNDO
was the transaction's first UNDO), so "undo_lsn==0" cannot work
anymore to indicate "this is not UNDO work". Using undo_lsn==LSN_ERROR
instead (this is an impossible LSN).
- store into CLR_END the type of log record which was undone
(INSERT/UPDATE/DELETE); needed for Recovery to know if/how it has
to update state.records if it sees this CLR_END in the REDO phase.
- when writing the CLR_END in _ma_apply_undo_row_insert(),
the place to store file's id is log_data+LSN_STORE_SIZE.
- in _ma_apply_undo_row_insert(), the records-- is moved
to a hook when writing the CLR_END (this way it is under log's mutex
which is needed for "recovery of the state")
storage/maria/ma_loghandler.c:
- all UNDOs, and CLR_END, start with the LSN of another UNDO; so
we can declare them "compressed".
- write_hook_for_clr_end() to set trn->undo_lsn (to the previous
UNDO's LSN) under log's lock (like UNDOs set trn->undo_lsn under log's
lock), and also update, if appropriate, state.records.
- reset share->id to 0 when deassigning; not useful for now but
sounds logical.
storage/maria/ma_recovery.c:
- if no table is found for a REDO, it's not an error; for an UNDO, it is
- in the REDO phase, when we see a CLR_END we must update trn->undo_lsn
and sometimes state.records.
- in the UNDO phase, when we execute an UNDO_ROW_INSERT:
* update trn->undo_lsn only after executing the record
* store the _previous_ undo_lsn into the CLR_END
- at the end of the REDO phase, when we recreate TRN objects, they
have already their long id in the log (either via a
LOGREC_LONG_TRANSACTION_ID, or in a checkpoint record), don't write
a new, useless LOGREC_LONG_TRANSACTION_ID for them.
storage/maria/ma_test1.c:
* where to stop execution is now driven by --testflag and not --test-undo
(ma_test2 already has --testflag for the same purpose). This allows
us to do a clean stop (with commit) at any point.
* --test-undo=# tells how to abort (flush all pages (which implies
flushing log) or only log or nothing); all such "ways of crashing"
are tested in ma_test_recovery
storage/maria/ma_test_recovery:
* Testing execution of UNDOs, with and without BLOBs.
* Testing idempotency of REDOs.
* See @todo for a probable bug with BLOBs.
* maria_chk -rq instead of -r, as with -q it nicely stops on any
problem in the data file (like the checksum bug see comment of
ma_blockrec.c).
* Testing if log was written by UNDO phase (often expected),
not written by REDO phase (always expected).
* Less output on the screen, compares with expected output in the end.
* some shell thingies like "set --" and $# are courtesy of
Danny and Pekka.
storage/maria/maria_read_log.c:
when only displaying the records, don't do an UNDO phase
storage/maria/ma_test_recovery.expected:
This is the expected output of a great part of ma_test_recovery.
ma_test_recovery compares its output to the expected output
and tells if different.
If we look at this file it mentions differences in checksum
(normal, it's not recovered yet) and in records count
(getting a correct records' count when recovery starts on an
already existing table, like when testing rollback,
is coded but not yet pushed).

checkpoints except that the index's Root (printed by maria_chk)
is more correct when using checkpoints. This is because checkpoint
flushed the state, so it happens to be correct, while no-checkpoint
does not flush the state, and recovery does not recover indexes
so Root is never fixed. When we recover indices, this will go away.

WL#3071 Maria checkpoint
Ability for flush_pagecache_blocks() to flush only certain pages of
a file, as instructed by an option "filter" pointer-to-function argument;
Checkpoint and background dirty page flushing use that to flush only
pages which have been dirty for long enough and bitmap pages.
Fix for a bug in flush_cached_blocks() (no idea if it could produce
a bug in real life, but theoretically it is).
Testing checkpoint in ma_test_recovery via ma_test1 and ma_test2.
Background checkpoint & dirty pages flush thread is still disabled
by default in ha_maria.

Added _ma_bitmap_wait_or_flush() to cause reader of bitmap pages to wait with reading until bitmap is flushed.
Use TAIL_PAGE_COUNT_MARKER for tail pages
Set 'sub_blocks' for and only for the head page or for the first extent of a blob. This is needed for store_extent_info() to be able to set START_EXTENT_BIT's
Don't allocate more than 0x3ffff pages in one extent (We need bit 0x4000 as a START_EXTENT_BIT)
Increase the calculated 'head_length' with the number of bytes used for extents.
Update row->space_on_head_page also in _ma_bitmap_find_new_place()
Make _ma_bitmap_get_page_bits() global. (Needed for UNDO handling)

Use PAGE_COUNT to mark if an extent is the start of of a blob. (Needed for extent_to_bitmap_blocks())
Added check_directory() for checking that directroy entries are correct.
Added checking of row checksums when reading rows (with EXTRA_DEBUG)
Added make_space_for_directory() and extend_directory() for doing expansion of directory

Changed _ma_apply_undo_row_delete() and _ma_apply_undo_row_update() to put row in it's original position
Ensure allocation of tail blocks are of at least MIN_TAIL_SIZE.
Ensure we store pages in pinned pages even if read failed. (If not we will have pages pinned forever in page cache)
Write original extent information in UNDO entry, not compacted ones (we need position to tails!)
When setting BLOCKUSED_USED, don't clear other bits (we have to preserve BLOCKUSED_USE_ORG_BITMAP)
Fixed som bugs in directory handling
Fixed bug where we wrote wrong lsn to blob pages
Added separate blob_buffer for fixing bug when updating row that had char/varchar that spanned several pages and also had blobs
Ensure we call _ma_bitmap_flushable() also in case of errors
When doing an update, first delete old entries, then search in bitmap for where to put new information
Info->s -> share
Rowid -> rowid
More DBUG_ASSERT()

Disable 'dummy' checksumming of pages as this gave false warnings.
(Need to investigate if this is ever needed)
storage/maria/ma_pagecache.c:
Fixed wrong shift that caused Maria to crash on files > 4G
storage/maria/ma_recovery.c:
In case of errors, start writing on new line if we where in %## %## printing mode (Made errors more readable)

Added check that we don't loop forever when handling undo's (in case of bug in undo chain)
Print name of failed REDO/UNDO
storage/maria/ma_recovery.h:
Removed old comment
storage/maria/ma_static.c:
Chaned version number of Maria files to not accidently use old ones (becasue of change of ordering of status variables)
storage/maria/ma_test2.c:
Added option -u to specify number of rows to update
Changed old option -u to be -A, as for ma_test1
Fixed bug in update of rows with blobs (before blobs was always reset to empty on update)
First created blob is now of max blob length to ensure we have at least one big blob in the table
storage/maria/ma_test_all.sh:
More tests
storage/maria/ma_test_recovery.expected:
Updated results
storage/maria/ma_test_recovery:
Changed tests to use bigger blobs (not just 1K)
Added new tests that tests recovery of update with blobs
Removed comparision of .MAD file as it's not guranteed that recovery from scratch gives identical data file as original update

Added --debug-on option to mysqld (to be able to turn of DBUG with --debug-on=0)
Fixed some bugs with 'non_flushable' marking of bitmap pages
Don't use 'non_flushable' marking of bitmap pages for not transactional tables
SHOW CREATE TABLE now shows if table was created with page checksums
Fixed a lot of bugs with BLOB handling in case of update/REDO and UNDO
More tests (especially for blobs) and DBUG_ASSERTS()
More readable output from maria_read_log and maria_chk
Fixed wrong shift that caused Maria to crash on files > 4G
Mark tables as crashed of REDO fails

Added _ma_bitmap_wait_or_flush() to cause reader of bitmap pages to wait with reading until bitmap is flushed.
Use TAIL_PAGE_COUNT_MARKER for tail pages
Set 'sub_blocks' for and only for the head page or for the first extent of a blob. This is needed for store_extent_info() to be able to set START_EXTENT_BIT's
Don't allocate more than 0x3ffff pages in one extent (We need bit 0x4000 as a START_EXTENT_BIT)
Increase the calculated 'head_length' with the number of bytes used for extents.
Update row->space_on_head_page also in _ma_bitmap_find_new_place()
Make _ma_bitmap_get_page_bits() global. (Needed for UNDO handling)

Some code simplications by adding new local variables
storage/maria/ma_blockrec.c:
UNDO of rows now puts back all part of the row on their original pages and positions.
Changed UNDO of DELETE and UNDO of UPDATE to contain information about the original length of data on head block and also extent information
This changes a lot of logic as now an insert of a row on a page may happen to any position (and not just to the first or next free)
Use PAGE_COUNT to mark if an extent is the start of of a blob. (Needed for extent_to_bitmap_blocks())
Added check_directory() for checking that directroy entries are correct.
Added checking of row checksums when reading rows (with EXTRA_DEBUG)
Added make_space_for_directory() and extend_directory() for doing expansion of directory
Added get_rowpos_in_head_or_tail_page() to be able to store head/tail on original position in UNDO

Added row->min_length to hold minmum required space needed on head page
Changed find_free_position() to use make_space_for_directory()
Changed make_empty_page() to allow optional creation of directory entry
Changed delete_head_or_tail() and _ma_apply_undo_row_isnert() to not copy pagecache block (speed optimization)
Changed _ma_apply_redo_insert_row_head_or_tail() to be able to insert new row at any position on 'new' page
Changed _ma_apply_undo_row_delete() and _ma_apply_undo_row_update() to put row in it's original position
Ensure allocation of tail blocks are of at least MIN_TAIL_SIZE.
Ensure we store pages in pinned pages even if read failed. (If not we will have pages pinned forever in page cache)
Write original extent information in UNDO entry, not compacted ones (we need position to tails!)
When setting BLOCKUSED_USED, don't clear other bits (we have to preserve BLOCKUSED_USE_ORG_BITMAP)
Fixed som bugs in directory handling
Fixed bug where we wrote wrong lsn to blob pages
Added separate blob_buffer for fixing bug when updating row that had char/varchar that spanned several pages and also had blobs
Ensure we call _ma_bitmap_flushable() also in case of errors
When doing an update, first delete old entries, then search in bitmap for where to put new information
Info->s -> share
Rowid -> rowid
More DBUG_ASSERT()
storage/maria/ma_blockrec.h:
Added START_EXTENT_BIT and TAIL_PAGE_COUNT_MARKER
Added _ma_bitmap_wait_or_flush() and _ma_bitmap_get_page_bits()
storage/maria/ma_check.c:
Don't write extra empty line if there is no deleted blocks
Ignore START_EXTENT_BIT's in page count
Call _ma_fast_unlock_key_del() to free key_del link

Disable 'dummy' checksumming of pages as this gave false warnings.
(Need to investigate if this is ever needed)
storage/maria/ma_pagecache.c:
Fixed wrong shift that caused Maria to crash on files > 4G
storage/maria/ma_recovery.c:
In case of errors, start writing on new line if we where in %## %## printing mode (Made errors more readable)
Changed global variable name from warnings -> recovery_warnings
Use MARIA_FILE_CREATE_RENAME_LSN_OFFSET instead of constant
Removed special handling of row position for deleted keys. Keys now always includes row positions
_ma_apply_undo_row_delete() now gets page and row position
Added check that we don't loop forever when handling undo's (in case of bug in undo chain)
Print name of failed REDO/UNDO

Removed old comment
storage/maria/ma_static.c:
Chaned version number of Maria files to not accidently use old ones (becasue of change of ordering of status variables)

First created blob is now of max blob length to ensure we have at least one big blob in the table
storage/maria/ma_test_all.sh:
More tests
storage/maria/ma_test_recovery.expected:
Updated results
storage/maria/ma_test_recovery:
Changed tests to use bigger blobs (not just 1K)
Added new tests that tests recovery of update with blobs
Removed comparision of .MAD file as it's not guranteed that recovery from scratch gives identical data file as original update

Updated results
storage/maria/ma_test_recovery:
Changed tests to use bigger blobs (not just 1K)

Simplify code (changed * to if)
storage/maria/maria_chk.c:
Make output more readable

Added --debug-on option to mysqld (to be able to turn of DBUG with --debug-on=0)
Fixed some bugs with 'non_flushable' marking of bitmap pages
Don't use 'non_flushable' marking of bitmap pages for not transactional tables
SHOW CREATE TABLE now shows if table was created with page checksums
Fixed a lot of bugs with BLOB handling in case of update/REDO and UNDO
More tests (especially for blobs) and DBUG_ASSERTS()
More readable output from maria_read_log and maria_chk
Fixed wrong shift that caused Maria to crash on files > 4G
Mark tables as crashed of REDO fails
dbug/dbug.c:
Changed to use my_bool (allowed me to remove some windows specific code)
Added variable _dbug_on_ to speed up execution when DBUG is not going to be used
Removed initialization of variables if not needed
include/my_dbug.h:
Use my_bool for some functions that was defined as BOOLEAN in dbug.c code

Define my_bool early
Increase MY_HOW_OFTEN_TO_WRITE as computers are now faster than 10 years ago

storage/maria/ha_maria.cc:
Store in create_info if page checksums are used (For SHOW CREATE TABLE)
storage/maria/ma_bitmap.c:
Added _ma_bitmap_wait_or_flush() to cause reader of bitmap pages to wait with reading until bitmap is flushed.
Use TAIL_PAGE_COUNT_MARKER for tail pages
Set 'sub_blocks' for and only for the head page or for the first extent of a blob. This is needed for store_extent_info() to be able to set START_EXTENT_BIT's
Don't allocate more than 0x3ffff pages in one extent (We need bit 0x4000 as a START_EXTENT_BIT)
Increase the calculated 'head_length' with the number of bytes used for extents.
Update row->space_on_head_page also in _ma_bitmap_find_new_place()
Make _ma_bitmap_get_page_bits() global. (Needed for UNDO handling)

This changes a lot of logic as now an insert of a row on a page may happen to any position (and not just to the first or next free)
Use PAGE_COUNT to mark if an extent is the start of of a blob. (Needed for extent_to_bitmap_blocks())
Added check_directory() for checking that directroy entries are correct.
Added checking of row checksums when reading rows (with EXTRA_DEBUG)
Added make_space_for_directory() and extend_directory() for doing expansion of directory

Changed _ma_apply_undo_row_delete() and _ma_apply_undo_row_update() to put row in it's original position
Ensure allocation of tail blocks are of at least MIN_TAIL_SIZE.
Ensure we store pages in pinned pages even if read failed. (If not we will have pages pinned forever in page cache)
Write original extent information in UNDO entry, not compacted ones (we need position to tails!)
When setting BLOCKUSED_USED, don't clear other bits (we have to preserve BLOCKUSED_USE_ORG_BITMAP)
Fixed som bugs in directory handling
Fixed bug where we wrote wrong lsn to blob pages
Added separate blob_buffer for fixing bug when updating row that had char/varchar that spanned several pages and also had blobs
Ensure we call _ma_bitmap_flushable() also in case of errors
When doing an update, first delete old entries, then search in bitmap for where to put new information
Info->s -> share
Rowid -> rowid
More DBUG_ASSERT()
storage/maria/ma_blockrec.h:
Added START_EXTENT_BIT and TAIL_PAGE_COUNT_MARKER
Added _ma_bitmap_wait_or_flush() and _ma_bitmap_get_page_bits()

Don't write extra empty line if there is no deleted blocks
Ignore START_EXTENT_BIT's in page count

WL#3072 - Maria Recovery
Bulk insert: don't log REDO/UNDO for rows, log one UNDO which will
truncate files; this is an optimization and a bugfix (table was left
half-repaired by crash).
Repair: mark table crashed-on-repair at start, bump skip_redo_lsn at start,
this is easier for recovery (tells it to skip old REDOs or even UNDO
phase) and user (tells it to repair) in case of crash, sync files
in the end.
Recovery skips missing or corrupted table and moves to next record
(in REDO or UNDO phase) to be more robust; warns if happens in UNDO phase.
Bugfix for UNDO_KEY_DELETE_WITH_ROOT (tested in ma_test_recovery)
and maria_enable_indexes().
Create missing bitmaps when needed (there can be more than one to create,
in rare cases), log a record for this.
include/myisamchk.h:
new flag: bulk insert repair mustn't bump create_rename_lsn
mysql-test/lib/mtr_report.pl:
skip normal warning in maria-recovery.test
mysql-test/r/maria-recovery.result:
result: crash before bulk insert is committed, causes proper rollback,
and crash right after OPTIMIZE replaces index file with new index file
leads to table marked corrupted and recovery not failing.
mysql-test/t/maria-recovery.test:
- can't check the table or it would commit the transaction,
but check is made after recovery.
- test of crash before bulk-insert-with-repair is committed
(to see if it is rolled back), and of crash after OPTIMIZE has replaced
index file but not finished all operations (to see if recovery fails -
it used to assert when trying to execute an old REDO on the new
index).
storage/maria/CMakeLists.txt:
new file
storage/maria/Makefile.am:
new file
storage/maria/ha_maria.cc:
- If bulk insert on a transactional table using an index repair:
table is initially empty, so don't log REDO/UNDO for data rows
(optimization), just log an UNDO_BULK_INSERT_WITH_REPAIR
which will, if executed, empty the data and index file. Re-enable
logging in end_bulk_insert().
- write log record for repair operation only after it's fully done,
index sort including (maria_repair*() used to write the log record).
- Adding back file->trn=NULL which was removed by mistake earlier.
storage/maria/ha_maria.h:
new member (see ha_maria.cc)
storage/maria/ma_bitmap.c:
Functions to create missing bitmaps:
- one function which creates missing bitmaps in page cache, except
the missing one with max offset which it does not put into page cache
as it will be modified very soon.
- one function which the one above calls, and creates bitmaps in page
cache
- one function to execute REDO_BITMAP_NEW_PAGE which uses the second
one above.
storage/maria/ma_blockrec.c:
- when logging REDO_DELETE_ALL, not only 'records' and 'checksum'
has to be reset under log's mutex.
- execution of REDO_INSERT_ROW_BLOBS now checks the dirty pages' list
- execution of UNDO_BULK_INSERT_WITH_REPAIR
storage/maria/ma_blockrec.h:
new functions
storage/maria/ma_check.c:
- table-flush-before-repair is moved to a separate function reused
by maria_sort_index(); syncing is added
- maria_repair() is allowed to re-enable logging only if it is the one
which disabled it.
- "_ma_flush_table_files_after_repair" was a bad name, it's not after
repair now, and it should not sync as we do more changes to the files
shortly after (sync is postponed to when writing the log record)
- REDO_REPAIR record should be written only after all repair
operations (in particular after sorting index in ha_mara::repair())
- close to the end of repair by sort, flushing of pages must happen
also in the non-quick case, to prepare for the sync at end.
- in parallel repair, some page flushes are not needed as done
by initialize_variables_for_repair().
storage/maria/ma_create.c:
Update skip_redo_lsn, create_rename_lsn optionally.
storage/maria/ma_delete_all.c:
Need to sync files at end of maria_delete_all_rows(), if transactional.
storage/maria/ma_extra.c:
During repair, we sometimes call _ma_flush_table_files() (via
_ma_flush_table_files_before_swap()) while there is a WRITE_CACHE.
storage/maria/ma_key_recover.c:
- when we see CLR_END for UNDO_BULK_INSERT_WITH_REPAIR, re-enable
indices.
- fixing bug: _ma_apply_undo_key_delete() parsed UNDO_KEY_DELETE_WITH_ROOT
wrongly, leading to recovery failure
storage/maria/ma_key_recover.h:
new prototype
storage/maria/ma_locking.c:
DBUG_VOID_RETURN missing
storage/maria/ma_loghandler.c:
UNDO for bulk insert with repair, and REDO for creating bitmaps.
LOGREC_FIRST_FREE to not have to change the for() every time we
add a new record type.
storage/maria/ma_loghandler.h:
new UNDO and REDO
storage/maria/ma_open.c:
Move share.kfile.file=kfile up a bit, so that _ma_update_state_lsns()
can get its value, this fixes a bug where LSN_REPAIRED_BY_MARIA_CHK
was not corrected on disk by maria_open().
Store skip_redo_lsn in index' header.
maria_enable_indexes() had a bug for BLOCK_RECORD, where an empty
file has one page, not 0 bytes.
storage/maria/ma_recovery.c:
- Skip a corrupted, missing, or repaired-with-maria_chk, table in
recovery: don't fail, just go to next REDO or UNDO; but if an UNDO
is skipped in UNDO phase we issue warnings.
- Skip REDO|UNDO in REDO phase if <skip_redo_lsn.
- If UNDO phase fails, delete transactions to not make trnman
assert.
- Update skip_redo_lsn when playing REDO_CREATE_TABLE
- Don't record UNDOs for old transactions which we don't know (long_trid==0)
- Bugfix for UNDO_KEY_DELETE_WITH_ROOT (see ma_key_recover.c)
- Execution of UNDO_BULK_INSERT_WITH_REPAIR
- Don't try to find a page number in REDO_DELETE_ALL
- Pieces moved to ma_recovery_util.c
storage/maria/ma_rename.c:
name change
storage/maria/ma_static.c:
I modified layout of the index' header (inserted skip_redo_lsn in its middle)
storage/maria/ma_test2.c:
allow breaking the test towards the end, tests execution of
UNDO_KEY_DELETE_WITH_ROOT
storage/maria/ma_test_recovery.expected:
6 as testflag instead of 4
storage/maria/ma_test_recovery:
Increase the amount of rollback work to do when testing recovery
with ma_test2; this reproduces the UNDO_KEY_DELETE_WITH_ROOT bug.
storage/maria/maria_chk.c:
skip_redo_lsn should be updated too, for consistency.
Write a REDO_REPAIR after all operations (including sort-records)
have been done.
No reason to flush blocks after maria_chk_data_link() and
maria_sort_records(), there is maria_close() in the end.
write_log_record() is a function, to not clutter maria_chk().
storage/maria/maria_def.h:
New member skip_redo_lsn in the state, and comments
storage/maria/maria_pack.c:
skip_redo_lsn should be updated too, for consistency
storage/maria/ma_recovery_util.c:
_ma_redo_not_needed_for_page(), defined in ma_recovery.c, is needed
by ma_blockrec.c; this causes link issues, resolved by putting
_ma_redo_not_needed_for_page() into a new file (so that it is not
in the same file as repair-related objects of ma_recovery.c).
storage/maria/ma_recovery_util.h:
new file

WL#3071 Maria checkpoint
Finally this is the real checkpoint code.
It however exhibits unstabilities when a checkpoint runs concurrently
with data-modifying clients (table corruption, transaction log's
assertions) so for now a checkpoint is taken only at startup after
recovery and at shutdown, i.e. not in concurrent situations. Later
we will let it run periodically, as well as flush dirty pages
periodically (almost all needed code is there already, only pagecache
code is written but not committed).
WL#3072 Maria recovery
* replacing UNDO_ROW_PURGE with CLR_END; testing of those CLR_END via
ma_test2 which has INSERTs failing with duplicate keys.
* replaying of REDO_RENAME_TABLE
Now, off to test Recovery in ha_maria :)

storage/maria/ha_maria.cc:
When ha_maria starts, do a recovery from last checkpoint.

storage/maria/ma_blockrec.c:
* even if my_sync() fails we have to my_close() (otherwise we leak
a descriptor)
* UNDO_ROW_PURGE is replaced by a simple CLR_END for UNDO_ROW_INSERT,
as promised in the old comment; it gives us skipping during the
UNDO phase.
storage/maria/ma_check.c:
All REDOs before create_rename_lsn are ignored by Recovery. So
create_rename_lsn must be set only after all data/index has been
flushed and forced to disk. We thus move write_log_record_for_repair()
to after _ma_flush_tables_files_after_repair().

maria_extra() update it under intern_lock. THR_LOCK_maria still needed
because of _ma_test_if_reopen().
storage/maria/ma_init.c:
destroy checkpoint module when Maria shuts down.
storage/maria/ma_loghandler.c:
* UNDO_ROW_PURGE gone (see ma_blockrec.c)
* we need to remember the LSN of the LOGREC_FILE_ID for a share,
because this LSN is needed into the checkpoint record (Recovery wants
to know the validity domain of an id->name mapping)
* translog_get_horizon_no_lock() needed for Checkpoint
* comment about failing assertion (Sanja knows)
* translog_init_reader_data() thought that translog_read_record_header_scan()
returns 0 in case of error, but 0 just means "0-length header".
* translog_assign_id_to_share() now needs the MARIA_HA because
LOGREC_FILE_ID uses a log-write hook.
* Verify that (de)assignment of share->id happens only under intern_lock,
as Checkpoint reads this id with intern_lock.
* translog_purge() can accept TRANSLOG_ADDRESS, not necessarily
a real LSN.

storage/maria/ma_pagecache.c:

storage/maria/ma_rename.c:

storage/maria/ma_test2.c:

* -t=1 now stops right after creating the table, so that
we can test undoing of INSERTs with duplicate keys (which tests the
CLR_END logged by _ma_write_abort_block_record()).
storage/maria/ma_test_recovery.expected:
Result of testing undoing of INSERTs with duplicate keys; there are

WL#3071 Maria checkpoint
Finally this is the real checkpoint code.
It however exhibits unstabilities when a checkpoint runs concurrently
with data-modifying clients (table corruption, transaction log's
assertions) so for now a checkpoint is taken only at startup after
recovery and at shutdown, i.e. not in concurrent situations. Later
we will let it run periodically, as well as flush dirty pages
periodically (almost all needed code is there already, only pagecache
code is written but not committed).
WL#3072 Maria recovery
* replacing UNDO_ROW_PURGE with CLR_END; testing of those CLR_END via
ma_test2 which has INSERTs failing with duplicate keys.
* replaying of REDO_RENAME_TABLE
Now, off to test Recovery in ha_maria :)

BitKeeper/deleted/.del-ma_least_recently_dirtied.h:

storage/maria/Makefile.am:
compile Checkpoint module
storage/maria/ha_maria.cc:
When ha_maria starts, do a recovery from last checkpoint.
Take a checkpoint when that recovery has ended and when ha_maria
shuts down cleanly.
storage/maria/ma_blockrec.c:
* even if my_sync() fails we have to my_close() (otherwise we leak
a descriptor)
* UNDO_ROW_PURGE is replaced by a simple CLR_END for UNDO_ROW_INSERT,
as promised in the old comment; it gives us skipping during the
UNDO phase.
storage/maria/ma_check.c:
All REDOs before create_rename_lsn are ignored by Recovery. So
create_rename_lsn must be set only after all data/index has been
flushed and forced to disk. We thus move write_log_record_for_repair()
to after _ma_flush_tables_files_after_repair().
storage/maria/ma_checkpoint.c:
Checkpoint module.
storage/maria/ma_checkpoint.h:
optional argument if caller wants a thread to periodically take
checkpoints and flush dirty pages.
storage/maria/ma_create.c:
* no need to init some vars as the initial bzero(share) takes care of this.
* update to new function's name
* even if we fail in my_sync() we have to my_close()
storage/maria/ma_extra.c:
Checkpoint reads share->last_version under intern_lock, so we make
maria_extra() update it under intern_lock. THR_LOCK_maria still needed
because of _ma_test_if_reopen().
storage/maria/ma_init.c:
destroy checkpoint module when Maria shuts down.
storage/maria/ma_loghandler.c:
* UNDO_ROW_PURGE gone (see ma_blockrec.c)
* we need to remember the LSN of the LOGREC_FILE_ID for a share,
because this LSN is needed into the checkpoint record (Recovery wants
to know the validity domain of an id->name mapping)
* translog_get_horizon_no_lock() needed for Checkpoint
* comment about failing assertion (Sanja knows)
* translog_init_reader_data() thought that translog_read_record_header_scan()
returns 0 in case of error, but 0 just means "0-length header".
* translog_assign_id_to_share() now needs the MARIA_HA because
LOGREC_FILE_ID uses a log-write hook.
* Verify that (de)assignment of share->id happens only under intern_lock,
as Checkpoint reads this id with intern_lock.
* translog_purge() can accept TRANSLOG_ADDRESS, not necessarily
a real LSN.
storage/maria/ma_loghandler.h:
prototype updates
storage/maria/ma_open.c:
no need to initialize "res"
storage/maria/ma_pagecache.c:
When taking a checkpoint, we don't need to know the maximum rec_lsn
of dirty pages; this LSN was intended to be used in the two-checkpoint
rule, but last_checkpoint_lsn is as good.
4 bytes for stored_list_size is enough as PAGECACHE::blocks (number
of blocks which the pagecache can contain) is int.
storage/maria/ma_pagecache.h:

storage/maria/ma_recovery.c:
* added replaying of REDO_RENAME_TABLE

* Recovery from the last checkpoint record now possible
* In new_table() we skip the table if the id->name mapping is older than
create_rename_lsn (mapping dates from lsn_of_file_id).
* in get_MARIA_HA_from_REDO_record() we skip the record
if the id->name mapping is newer than the record (can happen if processing
a record which is before the checkpoint record).
* parse_checkpoint_record() has to return a LSN, that's what caller expects
storage/maria/ma_rename.c:
new function's name; log end zeroes of tables' names (ease recovery)
storage/maria/ma_test2.c:
* equivalent of ma_test1's --test-undo added (named -u here).
* -t=1 now stops right after creating the table, so that
we can test undoing of INSERTs with duplicate keys (which tests the
CLR_END logged by _ma_write_abort_block_record()).
storage/maria/ma_test_recovery.expected:
Result of testing undoing of INSERTs with duplicate keys; there are
some differences in maria_chk -dvv but they are normal (removing
records does not shrink data/index file, does not put back the
"analyzed, optimized keys"(etc) index state.
storage/maria/ma_test_recovery:
Test undoing of INSERTs with duplicate keys, using ma_test2;
when such INSERT happens, it logs REDO_INSERT, UNDO_INSERT, REDO_DELETE,

Added versioning of row data
Will in future changeset (soon) av versioning of status variables (number of rows) and index
Changed some LEX_STRING to LEX_CUSTRING to avoid casts and warnings
Removed some not needed variables (as noticed by Guilhem)
include/maria.h:
Added prototypes for maria_chk_init_for_check(), maria_versioning() and maria_ignore_trids()
include/my_base.h:
Add new error HA_ERR_ROW_NOT_VISIBLE
include/myisamchk.h:
Added variables for checking visibility of rows during maria_chk
include/thr_lock.h:
Changed argument type from int to my_bool for get_status
Added variable allow_multiple_concurrent_insert, to signal if table supports multiple concurrent inserts
mysql-test/r/maria-page-checksum.result:
Added missing drop table
mysql-test/t/maria-page-checksum.test:
Added missing drop table
mysys/my_handler.c:
Added new error messages
mysys/thr_lock.c:
Added support for multiple concurrent inserts, if table handler supports it
sql/sql_yacc.yy:
Added LOCK TABLE table_name WRITE CONCURRENT
This was added (temporarly?) to be able to check versioning with Maria
storage/csv/ha_tina.cc:
Updated parameter for get_status
storage/maria/ha_maria.cc:
Added calls to maria_chk_init_status()
Fixed call to ma_control_file_open()
storage/maria/ma_blockrec.c:
Changed some LEX_STRING to LEX_CUSTRING to avoid casts and warnings
Changed back some 'header' parameters to const char*
Removed some casts
Added support for versioning:
- If info->row_flag & ROW_FLAG_TRANSID is set, store transaction id together with the row
- When reading rows, check if rows are visible. Give error if not
- When scanning table, ignore not visible rows
- Added function parameters to some functions, to be able to call _ma_compact_block_page() with different parameters depending of if the page is a HEAD or TAIL page
- _ma_compact_block_page() deletes transaction id's that are visible by all running transactions
- Added functions for thr_lock() to enable multiple concurrent inserts
- Added helper function 'mysql_versioning()' to enable/disable versioning
- Added helper function maria_ignore_trids(), used by maria_chk and maria_pack to see all rows.
storage/maria/ma_blockrec.h:
Updated parameters for some functions.
Added new functions to read/store state with thr_lock
storage/maria/ma_check.c:
Enable handling of transaction id's in rows
Give a readable error if a table contains a transation id that makes rows not visible
storage/maria/ma_control_file.c:
Added option to not give warning if control file doesn't exists.
storage/maria/ma_control_file.h:
Updated parameter lists for ma_control_file_open()

Always read control file (if exist) at start
Initialize checking of tables by calling maria_chk_init_for_check()
In verbose mode and in case of error, print max found transaction id
storage/maria/maria_def.h:
Added Trid to MARIA_ROW to be able to check transaction id for found row
Moved 'base_length' from MARIA_ROW to MARIA_HA to be able to handle different base length (with and without TRANSID) without if's
Added default row_flag to MARIA_HA for the same reason
Changed LEX_STRING -> LEX_CUSTRING to avoid casts in ma_blockrec.c
Removed not needed variables key_write_undo_lsn and key_delete_undo_lsn

Don't use 'non_flushable' marking of bitmap pages for not transactional tables
SHOW CREATE TABLE now shows if table was created with page checksums
Fixed a lot of bugs with BLOB handling in case of update/REDO and UNDO
More tests (especially for blobs) and DBUG_ASSERTS()

Added _ma_bitmap_wait_or_flush() to cause reader of bitmap pages to wait with reading until bitmap is flushed.
Use TAIL_PAGE_COUNT_MARKER for tail pages
Set 'sub_blocks' for and only for the head page or for the first extent of a blob. This is needed for store_extent_info() to be able to set START_EXTENT_BIT's
Don't allocate more than 0x3ffff pages in one extent (We need bit 0x4000 as a START_EXTENT_BIT)
Increase the calculated 'head_length' with the number of bytes used for extents.
Update row->space_on_head_page also in _ma_bitmap_find_new_place()
Make _ma_bitmap_get_page_bits() global. (Needed for UNDO handling)

storage/maria/ma_blockrec.c:
UNDO of rows now puts back all part of the row on their original pages and positions.
Changed UNDO of DELETE and UNDO of UPDATE to contain information about the original length of data on head block and also extent information
This changes a lot of logic as now an insert of a row on a page may happen to any position (and not just to the first or next free)
Use PAGE_COUNT to mark if an extent is the start of of a blob. (Needed for extent_to_bitmap_blocks())
Added check_directory() for checking that directroy entries are correct.
Added checking of row checksums when reading rows (with EXTRA_DEBUG)
Added make_space_for_directory() and extend_directory() for doing expansion of directory

Added row->min_length to hold minmum required space needed on head page
Changed find_free_position() to use make_space_for_directory()
Changed make_empty_page() to allow optional creation of directory entry
Changed delete_head_or_tail() and _ma_apply_undo_row_isnert() to not copy pagecache block (speed optimization)
Changed _ma_apply_redo_insert_row_head_or_tail() to be able to insert new row at any position on 'new' page
Changed _ma_apply_undo_row_delete() and _ma_apply_undo_row_update() to put row in it's original position
Ensure allocation of tail blocks are of at least MIN_TAIL_SIZE.
Ensure we store pages in pinned pages even if read failed. (If not we will have pages pinned forever in page cache)
Write original extent information in UNDO entry, not compacted ones (we need position to tails!)
When setting BLOCKUSED_USED, don't clear other bits (we have to preserve BLOCKUSED_USE_ORG_BITMAP)
Fixed som bugs in directory handling
Fixed bug where we wrote wrong lsn to blob pages
Added separate blob_buffer for fixing bug when updating row that had char/varchar that spanned several pages and also had blobs
Ensure we call _ma_bitmap_flushable() also in case of errors
When doing an update, first delete old entries, then search in bitmap for where to put new information
Info->s -> share
Rowid -> rowid
More DBUG_ASSERT()
storage/maria/ma_blockrec.h:
Added START_EXTENT_BIT and TAIL_PAGE_COUNT_MARKER
Added _ma_bitmap_wait_or_flush() and _ma_bitmap_get_page_bits()
storage/maria/ma_check.c:
Don't write extra empty line if there is no deleted blocks
Ignore START_EXTENT_BIT's in page count
Call _ma_fast_unlock_key_del() to free key_del link

storage/maria/ma_open.c:
Moved state->changed to be at start of state info on disk to allow one to easly mark files as crashed
storage/maria/ma_page.c:
Disable 'dummy' checksumming of pages as this gave false warnings.
(Need to investigate if this is ever needed)
storage/maria/ma_pagecache.c:
Fixed wrong shift that caused Maria to crash on files > 4G
storage/maria/ma_recovery.c:
In case of errors, start writing on new line if we where in %## %## printing mode (Made errors more readable)
Changed global variable name from warnings -> recovery_warnings
Use MARIA_FILE_CREATE_RENAME_LSN_OFFSET instead of constant
Removed special handling of row position for deleted keys. Keys now always includes row positions
_ma_apply_undo_row_delete() now gets page and row position
Added check that we don't loop forever when handling undo's (in case of bug in undo chain)
Print name of failed REDO/UNDO
storage/maria/ma_recovery.h:
Removed old comment
storage/maria/ma_static.c:
Chaned version number of Maria files to not accidently use old ones (becasue of change of ordering of status variables)

Added option -u to specify number of rows to update
Changed old option -u to be -A, as for ma_test1
Fixed bug in update of rows with blobs (before blobs was always reset to empty on update)
First created blob is now of max blob length to ensure we have at least one big blob in the table
storage/maria/ma_test_all.sh:
More tests
storage/maria/ma_test_recovery.expected:
Updated results
storage/maria/ma_test_recovery:
Changed tests to use bigger blobs (not just 1K)
Added new tests that tests recovery of update with blobs
Removed comparision of .MAD file as it's not guranteed that recovery from scratch gives identical data file as original update

Simplify code (changed * to if)
storage/maria/maria_chk.c:
Make output more readable

Ensure allocation of tail blocks are of at least MIN_TAIL_SIZE.
Ensure we store pages in pinned pages even if read failed. (If not we will have pages pinned forever in page cache)
Write original extent information in UNDO entry, not compacted ones (we need position to tails!)
When setting BLOCKUSED_USED, don't clear other bits (we have to preserve BLOCKUSED_USE_ORG_BITMAP)
Fixed som bugs in directory handling
Fixed bug where we wrote wrong lsn to blob pages
Added separate blob_buffer for fixing bug when updating row that had char/varchar that spanned several pages and also had blobs
Ensure we call _ma_bitmap_flushable() also in case of errors

UNDO of rows now puts back all part of the row on their original pages and positions
Added variable _dbug_on_ to speed up execution when DBUG is not going to be used
Added --debug-on option to mysqld (to be able to turn of DBUG with --debug-on=0)
Fixed some bugs with 'non_flushable' marking of bitmap pages
Don't use 'non_flushable' marking of bitmap pages for not transactional tables
SHOW CREATE TABLE now shows if table was created with page checksums
Fixed a lot of bugs with BLOB handling in case of update/REDO and UNDO
More tests (especially for blobs) and DBUG_ASSERTS()
More readable output from maria_read_log and maria_chk
Fixed wrong shift that caused Maria to crash on files > 4G
Mark tables as crashed of REDO fails
dbug/dbug.c:
Changed to use my_bool (allowed me to remove some windows specific code)
Added variable _dbug_on_ to speed up execution when DBUG is not going to be used
Removed initialization of variables if not needed
include/my_dbug.h:
Use my_bool for some functions that was defined as BOOLEAN in dbug.c code

storage/maria/ha_maria.cc:
Store in create_info if page checksums are used (For SHOW CREATE TABLE)
storage/maria/ma_bitmap.c:
Added _ma_bitmap_wait_or_flush() to cause reader of bitmap pages to wait with reading until bitmap is flushed.
Use TAIL_PAGE_COUNT_MARKER for tail pages
Set 'sub_blocks' for and only for the head page or for the first extent of a blob. This is needed for store_extent_info() to be able to set START_EXTENT_BIT's
Don't allocate more than 0x3ffff pages in one extent (We need bit 0x4000 as a START_EXTENT_BIT)
Increase the calculated 'head_length' with the number of bytes used for extents.
Update row->space_on_head_page also in _ma_bitmap_find_new_place()
Make _ma_bitmap_get_page_bits() global. (Needed for UNDO handling)

Use PAGE_COUNT to mark if an extent is the start of of a blob. (Needed for extent_to_bitmap_blocks())
Added check_directory() for checking that directroy entries are correct.
Added checking of row checksums when reading rows (with EXTRA_DEBUG)
Added make_space_for_directory() and extend_directory() for doing expansion of directory

Added ma_test_big.sh
storage/maria/ha_maria.cc:
Store in create_info if page checksums are used (For SHOW CREATE TABLE)
storage/maria/ma_bitmap.c:
Added _ma_bitmap_wait_or_flush() to cause reader of bitmap pages to wait with reading until bitmap is flushed.
Use TAIL_PAGE_COUNT_MARKER for tail pages
Set 'sub_blocks' for and only for the head page or for the first extent of a blob. This is needed for store_extent_info() to be able to set START_EXTENT_BIT's
Don't allocate more than 0x3ffff pages in one extent (We need bit 0x4000 as a START_EXTENT_BIT)
Increase the calculated 'head_length' with the number of bytes used for extents.
Update row->space_on_head_page also in _ma_bitmap_find_new_place()
Make _ma_bitmap_get_page_bits() global. (Needed for UNDO handling)
Changed _ma_bitmap_flushable() to take MARIA_HA instead of MARIA_SHARE.
This was needed to be able to mark the handler if we had a 'non_flushable' call pending or not.
Don't use 'non_flushable' marking of bitmap pages for not transactional tables.
Added BLOCKUSED_USE_ORG_BITMAP handling also for tail pages.
Added more DBUG_ASSERT() to find possible errors in other code
Some code simplications by adding new local variables
storage/maria/ma_blockrec.c:
UNDO of rows now puts back all part of the row on their original pages and positions.
Changed UNDO of DELETE and UNDO of UPDATE to contain information about the original length of data on head block and also extent information
This changes a lot of logic as now an insert of a row on a page may happen to any position (and not just to the first or next free)
Use PAGE_COUNT to mark if an extent is the start of of a blob. (Needed for extent_to_bitmap_blocks())
Added check_directory() for checking that directroy entries are correct.
Added checking of row checksums when reading rows (with EXTRA_DEBUG)
Added make_space_for_directory() and extend_directory() for doing expansion of directory
Added get_rowpos_in_head_or_tail_page() to be able to store head/tail on original position in UNDO
Added extent_to_bitmap_blocks() to be able to generate original bitmap blocks from UNDO entry
Added _ma_update_at_original_place() for UNDO of DELETES
Added row->min_length to hold minmum required space needed on head page
Changed find_free_position() to use make_space_for_directory()
Changed make_empty_page() to allow optional creation of directory entry
Changed delete_head_or_tail() and _ma_apply_undo_row_isnert() to not copy pagecache block (speed optimization)
Changed _ma_apply_redo_insert_row_head_or_tail() to be able to insert new row at any position on 'new' page
Changed _ma_apply_undo_row_delete() and _ma_apply_undo_row_update() to put row in it's original position
Ensure allocation of tail blocks are of at least MIN_TAIL_SIZE.
Ensure we store pages in pinned pages even if read failed. (If not we will have pages pinned forever in page cache)
Write original extent information in UNDO entry, not compacted ones (we need position to tails!)
When setting BLOCKUSED_USED, don't clear other bits (we have to preserve BLOCKUSED_USE_ORG_BITMAP)
Fixed som bugs in directory handling
Fixed bug where we wrote wrong lsn to blob pages
Added separate blob_buffer for fixing bug when updating row that had char/varchar that spanned several pages and also had blobs
Ensure we call _ma_bitmap_flushable() also in case of errors
When doing an update, first delete old entries, then search in bitmap for where to put new information
Info->s -> share
Rowid -> rowid
More DBUG_ASSERT()
storage/maria/ma_blockrec.h:
Added START_EXTENT_BIT and TAIL_PAGE_COUNT_MARKER
Added _ma_bitmap_wait_or_flush() and _ma_bitmap_get_page_bits()
storage/maria/ma_check.c:
Don't write extra empty line if there is no deleted blocks
Ignore START_EXTENT_BIT's in page count
Call _ma_fast_unlock_key_del() to free key_del link
storage/maria/ma_close.c:
Ensure that used_key_del is 0. (If not, someone forgot to call _ma_unlock_key_del())
storage/maria/ma_create.c:
Changed constant to macro
storage/maria/ma_delete.c:
For deleted keys, log also position to row
storage/maria/ma_extra.c:
Release blob buffer at maria_reset() if bigger than MARIA_SMALL_BLOB_BUFFER
storage/maria/ma_key_recover.c:
Added bzero() of LSN that confused paged cache in case of uninitialized block
Mark file crashed if applying of index changes fails
Added calls to _ma_fast_unlock_key_del() for protection of shared key_del link.
storage/maria/ma_locking.c:
Added usage of MARIA_FILE_OPEN_COUNT_OFFSET
Added _ma_mark_file_crashed()
storage/maria/ma_loghandler.c:
Fixed bug where we logged uninitialized memory
storage/maria/ma_open.c:
Moved state->changed to be at start of state info on disk to allow one to easly mark files as crashed
storage/maria/ma_page.c:
Disable 'dummy' checksumming of pages as this gave false warnings.
(Need to investigate if this is ever needed)
storage/maria/ma_pagecache.c:
Fixed wrong shift that caused Maria to crash on files > 4G
storage/maria/ma_recovery.c:
In case of errors, start writing on new line if we where in %## %## printing mode (Made errors more readable)
Changed global variable name from warnings -> recovery_warnings
Use MARIA_FILE_CREATE_RENAME_LSN_OFFSET instead of constant
Removed special handling of row position for deleted keys. Keys now always includes row positions
_ma_apply_undo_row_delete() now gets page and row position
Added check that we don't loop forever when handling undo's (in case of bug in undo chain)
Print name of failed REDO/UNDO
storage/maria/ma_recovery.h:
Removed old comment
storage/maria/ma_static.c:
Chaned version number of Maria files to not accidently use old ones (becasue of change of ordering of status variables)
storage/maria/ma_test2.c:
Added option -u to specify number of rows to update
Changed old option -u to be -A, as for ma_test1
Fixed bug in update of rows with blobs (before blobs was always reset to empty on update)
First created blob is now of max blob length to ensure we have at least one big blob in the table
storage/maria/ma_test_all.sh:
More tests
storage/maria/ma_test_recovery.expected:
Updated results
storage/maria/ma_test_recovery:
Changed tests to use bigger blobs (not just 1K)
Added new tests that tests recovery of update with blobs
Removed comparision of .MAD file as it's not guranteed that recovery from scratch gives identical data file as original update
(compact_page() may be called at different times during normal execution and during REDO)
storage/maria/ma_update.c:
Simplify code (changed * to if)
storage/maria/maria_chk.c:
Make output more readable
storage/maria/maria_def.h:
Changed 'changed' to int to prepare for more bits

Fixed bug in update of rows with blobs (before blobs was always reset to empty on update)
storage/maria/ma_test_big.sh:
Testing of insert, update, delete, recovery and undo of rows with blobs
Thanks to the random-ness of ma_test2 this is likely to find most bugs in the row handling

WL#3072 - Maria Recovery
Bulk insert: don't log REDO/UNDO for rows, log one UNDO which will
truncate files; this is an optimization and a bugfix (table was left
half-repaired by crash).
Repair: mark table crashed-on-repair at start, bump skip_redo_lsn at start,
this is easier for recovery (tells it to skip old REDOs or even UNDO
phase) and user (tells it to repair) in case of crash, sync files
in the end.
Recovery skips missing or corrupted table and moves to next record
(in REDO or UNDO phase) to be more robust; warns if happens in UNDO phase.
Bugfix for UNDO_KEY_DELETE_WITH_ROOT (tested in ma_test_recovery)
and maria_enable_indexes().
Create missing bitmaps when needed (there can be more than one to create,
in rare cases), log a record for this.
include/myisamchk.h:
new flag: bulk insert repair mustn't bump create_rename_lsn
mysql-test/lib/mtr_report.pl:
skip normal warning in maria-recovery.test
mysql-test/r/maria-recovery.result:
result: crash before bulk insert is committed, causes proper rollback,
and crash right after OPTIMIZE replaces index file with new index file
leads to table marked corrupted and recovery not failing.
mysql-test/t/maria-recovery.test:
- can't check the table or it would commit the transaction,
but check is made after recovery.
- test of crash before bulk-insert-with-repair is committed
(to see if it is rolled back), and of crash after OPTIMIZE has replaced
index file but not finished all operations (to see if recovery fails -
it used to assert when trying to execute an old REDO on the new
index).
storage/maria/CMakeLists.txt:
new file
storage/maria/Makefile.am:
new file
storage/maria/ha_maria.cc:
- If bulk insert on a transactional table using an index repair:
table is initially empty, so don't log REDO/UNDO for data rows
(optimization), just log an UNDO_BULK_INSERT_WITH_REPAIR
which will, if executed, empty the data and index file. Re-enable
logging in end_bulk_insert().
- write log record for repair operation only after it's fully done,
index sort including (maria_repair*() used to write the log record).
- Adding back file->trn=NULL which was removed by mistake earlier.
storage/maria/ha_maria.h:
new member (see ha_maria.cc)
storage/maria/ma_bitmap.c:
Functions to create missing bitmaps:
- one function which creates missing bitmaps in page cache, except
the missing one with max offset which it does not put into page cache
as it will be modified very soon.
- one function which the one above calls, and creates bitmaps in page
cache
- one function to execute REDO_BITMAP_NEW_PAGE which uses the second
one above.
storage/maria/ma_blockrec.c:
- when logging REDO_DELETE_ALL, not only 'records' and 'checksum'
has to be reset under log's mutex.
- execution of REDO_INSERT_ROW_BLOBS now checks the dirty pages' list
- execution of UNDO_BULK_INSERT_WITH_REPAIR
storage/maria/ma_blockrec.h:
new functions
storage/maria/ma_check.c:
- table-flush-before-repair is moved to a separate function reused
by maria_sort_index(); syncing is added
- maria_repair() is allowed to re-enable logging only if it is the one
which disabled it.
- "_ma_flush_table_files_after_repair" was a bad name, it's not after
repair now, and it should not sync as we do more changes to the files
shortly after (sync is postponed to when writing the log record)
- REDO_REPAIR record should be written only after all repair
operations (in particular after sorting index in ha_mara::repair())
- close to the end of repair by sort, flushing of pages must happen
also in the non-quick case, to prepare for the sync at end.
- in parallel repair, some page flushes are not needed as done
by initialize_variables_for_repair().
storage/maria/ma_create.c:
Update skip_redo_lsn, create_rename_lsn optionally.
storage/maria/ma_delete_all.c:
Need to sync files at end of maria_delete_all_rows(), if transactional.
storage/maria/ma_extra.c:
During repair, we sometimes call _ma_flush_table_files() (via
_ma_flush_table_files_before_swap()) while there is a WRITE_CACHE.
storage/maria/ma_key_recover.c:
- when we see CLR_END for UNDO_BULK_INSERT_WITH_REPAIR, re-enable
indices.
- fixing bug: _ma_apply_undo_key_delete() parsed UNDO_KEY_DELETE_WITH_ROOT
wrongly, leading to recovery failure
storage/maria/ma_key_recover.h:
new prototype
storage/maria/ma_locking.c:
DBUG_VOID_RETURN missing
storage/maria/ma_loghandler.c:
UNDO for bulk insert with repair, and REDO for creating bitmaps.
LOGREC_FIRST_FREE to not have to change the for() every time we
add a new record type.
storage/maria/ma_loghandler.h:
new UNDO and REDO
storage/maria/ma_open.c:
Move share.kfile.file=kfile up a bit, so that _ma_update_state_lsns()
can get its value, this fixes a bug where LSN_REPAIRED_BY_MARIA_CHK
was not corrected on disk by maria_open().
Store skip_redo_lsn in index' header.
maria_enable_indexes() had a bug for BLOCK_RECORD, where an empty
file has one page, not 0 bytes.
storage/maria/ma_recovery.c:
- Skip a corrupted, missing, or repaired-with-maria_chk, table in
recovery: don't fail, just go to next REDO or UNDO; but if an UNDO
is skipped in UNDO phase we issue warnings.
- Skip REDO|UNDO in REDO phase if <skip_redo_lsn.
- If UNDO phase fails, delete transactions to not make trnman
assert.
- Update skip_redo_lsn when playing REDO_CREATE_TABLE
- Don't record UNDOs for old transactions which we don't know (long_trid==0)
- Bugfix for UNDO_KEY_DELETE_WITH_ROOT (see ma_key_recover.c)
- Execution of UNDO_BULK_INSERT_WITH_REPAIR
- Don't try to find a page number in REDO_DELETE_ALL
- Pieces moved to ma_recovery_util.c
storage/maria/ma_rename.c:
name change
storage/maria/ma_static.c:
I modified layout of the index' header (inserted skip_redo_lsn in its middle)
storage/maria/ma_test2.c:
allow breaking the test towards the end, tests execution of
UNDO_KEY_DELETE_WITH_ROOT
storage/maria/ma_test_recovery.expected:
6 as testflag instead of 4
storage/maria/ma_test_recovery:
Increase the amount of rollback work to do when testing recovery
with ma_test2; this reproduces the UNDO_KEY_DELETE_WITH_ROOT bug.
storage/maria/maria_chk.c:
skip_redo_lsn should be updated too, for consistency.
Write a REDO_REPAIR after all operations (including sort-records)
have been done.
No reason to flush blocks after maria_chk_data_link() and
maria_sort_records(), there is maria_close() in the end.
write_log_record() is a function, to not clutter maria_chk().
storage/maria/maria_def.h:
New member skip_redo_lsn in the state, and comments
storage/maria/maria_pack.c:
skip_redo_lsn should be updated too, for consistency
storage/maria/ma_recovery_util.c:
_ma_redo_not_needed_for_page(), defined in ma_recovery.c, is needed
by ma_blockrec.c; this causes link issues, resolved by putting
_ma_redo_not_needed_for_page() into a new file (so that it is not
in the same file as repair-related objects of ma_recovery.c).
storage/maria/ma_recovery_util.h:

Ensure allocation of tail blocks are of at least MIN_TAIL_SIZE.
Ensure we store pages in pinned pages even if read failed. (If not we will have pages pinned forever in page cache)
Write original extent information in UNDO entry, not compacted ones (we need position to tails!)
When setting BLOCKUSED_USED, don't clear other bits (we have to preserve BLOCKUSED_USE_ORG_BITMAP)
Fixed som bugs in directory handling
Fixed bug where we wrote wrong lsn to blob pages
Added separate blob_buffer for fixing bug when updating row that had char/varchar that spanned several pages and also had blobs
Ensure we call _ma_bitmap_flushable() also in case of errors
When doing an update, first delete old entries, then search in bitmap for where to put new information
Info->s -> share
Rowid -> rowid

Updated results
storage/maria/ma_test_recovery:
Changed tests to use bigger blobs (not just 1K)

WL#3072 Maria Recovery
misc fixes of execution of UNDOs in the UNDO phase:
- into the CLR_END, store the LSN of the _previous_ UNDO (we debated
what was best, so far we're going with "previous"; later we can change
to "current" if needed), and store the type of record which is being
undone (needed to know how to update state.records when we see the
CLR_END during the REDO phase).
- declaring all UNDOs and CLR_END as "compressed"
- when executing an UNDO in the UNDO phase, state.records is updated
as a hook when writing CLR_END (needed for "recovery of the state"),
and so is trn->undo_lsn (needed for when we have checkpoints).
- bugfix (execution of UNDO_ROW_DELETE didn't store the correct checksum
into the re-inserted row, maria_chk -r thus threw the row away).
- modifications of ma_test1: where to stop is now driven by --testflag;
--test-undo just tells how to stop (flush data, flush log, nothing).
- ma_test_recovery: testing of the UNDO phase, more testing of the
REDO phase, identification of a bug.
storage/maria/ma_blockrec.c:
- bugfix: execution of UNDO_ROW_DELETE didn't store the correct
checksum into the row (leading to "maria_chk -r" eliminating the
re-inserted row, net effect was that rollback appeared to have
rolled back no deletion). Reason was that write_block_record() used
info->cur_row.checksum, while "row" can be != &info->cur_row
(case of UNDO_ROW_DELETE). After fixing this, problems with
_ma_update_block_record() appeared; indeed checksum was computed
by allocate_and_write_block_record() while _ma_update_block_record()
directly calls write_block_record(). Solution is to compute checksum
in write_block_record() instead.
- when executing an UNDO, we now pass the LSN of the _previous_ UNDO
to block_format functions. This LSN can be 0 (if the being-executed UNDO
was the transaction's first UNDO), so "undo_lsn==0" cannot work
anymore to indicate "this is not UNDO work". Using undo_lsn==LSN_ERROR
instead (this is an impossible LSN).
- store into CLR_END the type of log record which was undone
(INSERT/UPDATE/DELETE); needed for Recovery to know if/how it has
to update state.records if it sees this CLR_END in the REDO phase.
- when writing the CLR_END in _ma_apply_undo_row_insert(),
the place to store file's id is log_data+LSN_STORE_SIZE.
- in _ma_apply_undo_row_insert(), the records-- is moved
to a hook when writing the CLR_END (this way it is under log's mutex
which is needed for "recovery of the state")
storage/maria/ma_loghandler.c:
- all UNDOs, and CLR_END, start with the LSN of another UNDO; so
we can declare them "compressed".
- write_hook_for_clr_end() to set trn->undo_lsn (to the previous
UNDO's LSN) under log's lock (like UNDOs set trn->undo_lsn under log's
lock), and also update, if appropriate, state.records.
- reset share->id to 0 when deassigning; not useful for now but
sounds logical.
storage/maria/ma_recovery.c:
- if no table is found for a REDO, it's not an error; for an UNDO, it is
- in the REDO phase, when we see a CLR_END we must update trn->undo_lsn
and sometimes state.records.
- in the UNDO phase, when we execute an UNDO_ROW_INSERT:
* update trn->undo_lsn only after executing the record
* store the _previous_ undo_lsn into the CLR_END
- at the end of the REDO phase, when we recreate TRN objects, they
have already their long id in the log (either via a
LOGREC_LONG_TRANSACTION_ID, or in a checkpoint record), don't write
a new, useless LOGREC_LONG_TRANSACTION_ID for them.
storage/maria/ma_test1.c:
* where to stop execution is now driven by --testflag and not --test-undo
(ma_test2 already has --testflag for the same purpose). This allows
us to do a clean stop (with commit) at any point.
* --test-undo=# tells how to abort (flush all pages (which implies
flushing log) or only log or nothing); all such "ways of crashing"
are tested in ma_test_recovery
storage/maria/ma_test_recovery:
* Testing execution of UNDOs, with and without BLOBs.
* Testing idempotency of REDOs.
* See @todo for a probable bug with BLOBs.
* maria_chk -rq instead of -r, as with -q it nicely stops on any
problem in the data file (like the checksum bug see comment of
ma_blockrec.c).
* Testing if log was written by UNDO phase (often expected),
not written by REDO phase (always expected).
* Less output on the screen, compares with expected output in the end.
* some shell thingies like "set --" and $# are courtesy of
Danny and Pekka.
storage/maria/maria_read_log.c:
when only displaying the records, don't do an UNDO phase
storage/maria/ma_test_recovery.expected:
This is the expected output of a great part of ma_test_recovery.
ma_test_recovery compares its output to the expected output
and tells if different.
If we look at this file it mentions differences in checksum
(normal, it's not recovered yet) and in records count
(getting a correct records' count when recovery starts on an
already existing table, like when testing rollback,
is coded but not yet pushed).

WL#3072 Maria Recovery
misc fixes of execution of UNDOs in the UNDO phase:
- into the CLR_END, store the LSN of the _previous_ UNDO (we debated
what was best, so far we're going with "previous"; later we can change
to "current" if needed), and store the type of record which is being
undone (needed to know how to update state.records when we see the
CLR_END during the REDO phase).
- declaring all UNDOs and CLR_END as "compressed"
- when executing an UNDO in the UNDO phase, state.records is updated
as a hook when writing CLR_END (needed for "recovery of the state"),
and so is trn->undo_lsn (needed for when we have checkpoints).
- bugfix (execution of UNDO_ROW_DELETE didn't store the correct checksum
into the re-inserted row, maria_chk -r thus threw the row away).
- modifications of ma_test1: where to stop is now driven by --testflag;
--test-undo just tells how to stop (flush data, flush log, nothing).
- ma_test_recovery: testing of the UNDO phase, more testing of the
REDO phase, identification of a bug.
storage/maria/ma_blockrec.c:
- bugfix: execution of UNDO_ROW_DELETE didn't store the correct
checksum into the row (leading to "maria_chk -r" eliminating the
re-inserted row, net effect was that rollback appeared to have
rolled back no deletion). Reason was that write_block_record() used
info->cur_row.checksum, while "row" can be != &info->cur_row
(case of UNDO_ROW_DELETE). After fixing this, problems with
_ma_update_block_record() appeared; indeed checksum was computed
by allocate_and_write_block_record() while _ma_update_block_record()
directly calls write_block_record(). Solution is to compute checksum
in write_block_record() instead.
- when executing an UNDO, we now pass the LSN of the _previous_ UNDO
to block_format functions. This LSN can be 0 (if the being-executed UNDO
was the transaction's first UNDO), so "undo_lsn==0" cannot work
anymore to indicate "this is not UNDO work". Using undo_lsn==LSN_ERROR
instead (this is an impossible LSN).
- store into CLR_END the type of log record which was undone
(INSERT/UPDATE/DELETE); needed for Recovery to know if/how it has
to update state.records if it sees this CLR_END in the REDO phase.
- when writing the CLR_END in _ma_apply_undo_row_insert(),
the place to store file's id is log_data+LSN_STORE_SIZE.
- in _ma_apply_undo_row_insert(), the records-- is moved
to a hook when writing the CLR_END (this way it is under log's mutex
which is needed for "recovery of the state")
storage/maria/ma_loghandler.c:
- all UNDOs, and CLR_END, start with the LSN of another UNDO; so
we can declare them "compressed".
- write_hook_for_clr_end() to set trn->undo_lsn (to the previous
UNDO's LSN) under log's lock (like UNDOs set trn->undo_lsn under log's
lock), and also update, if appropriate, state.records.
- reset share->id to 0 when deassigning; not useful for now but
sounds logical.
storage/maria/ma_recovery.c:
- if no table is found for a REDO, it's not an error; for an UNDO, it is
- in the REDO phase, when we see a CLR_END we must update trn->undo_lsn
and sometimes state.records.
- in the UNDO phase, when we execute an UNDO_ROW_INSERT:
* update trn->undo_lsn only after executing the record
* store the _previous_ undo_lsn into the CLR_END
- at the end of the REDO phase, when we recreate TRN objects, they
have already their long id in the log (either via a
LOGREC_LONG_TRANSACTION_ID, or in a checkpoint record), don't write
a new, useless LOGREC_LONG_TRANSACTION_ID for them.
storage/maria/ma_test1.c:
* where to stop execution is now driven by --testflag and not --test-undo
(ma_test2 already has --testflag for the same purpose). This allows
us to do a clean stop (with commit) at any point.
* --test-undo=# tells how to abort (flush all pages (which implies
flushing log) or only log or nothing); all such "ways of crashing"
are tested in ma_test_recovery
storage/maria/ma_test_recovery:
* Testing execution of UNDOs, with and without BLOBs.
* Testing idempotency of REDOs.
* See @todo for a probable bug with BLOBs.
* maria_chk -rq instead of -r, as with -q it nicely stops on any
problem in the data file (like the checksum bug see comment of
ma_blockrec.c).
* Testing if log was written by UNDO phase (often expected),
not written by REDO phase (always expected).
* Less output on the screen, compares with expected output in the end.
* some shell thingies like "set --" and $# are courtesy of
Danny and Pekka.
storage/maria/maria_read_log.c:
when only displaying the records, don't do an UNDO phase
storage/maria/ma_test_recovery.expected:
This is the expected output of a great part of ma_test_recovery.
ma_test_recovery compares its output to the expected output
and tells if different.
If we look at this file it mentions differences in checksum
(normal, it's not recovered yet) and in records count
(getting a correct records' count when recovery starts on an
already existing table, like when testing rollback,
is coded but not yet pushed).

Fixed som bugs in directory handling
Fixed bug where we wrote wrong lsn to blob pages
Added separate blob_buffer for fixing bug when updating row that had char/varchar that spanned several pages and also had blobs

WL#3071 Maria checkpoint
Finally this is the real checkpoint code.
It however exhibits unstabilities when a checkpoint runs concurrently
with data-modifying clients (table corruption, transaction log's
assertions) so for now a checkpoint is taken only at startup after
recovery and at shutdown, i.e. not in concurrent situations. Later
we will let it run periodically, as well as flush dirty pages
periodically (almost all needed code is there already, only pagecache
code is written but not committed).
WL#3072 Maria recovery
* replacing UNDO_ROW_PURGE with CLR_END; testing of those CLR_END via
ma_test2 which has INSERTs failing with duplicate keys.
* replaying of REDO_RENAME_TABLE
Now, off to test Recovery in ha_maria :)
BitKeeper/deleted/.del-ma_least_recently_dirtied.c:
Delete: storage/maria/ma_least_recently_dirtied.c
BitKeeper/deleted/.del-ma_least_recently_dirtied.h:
Delete: storage/maria/ma_least_recently_dirtied.h
storage/maria/Makefile.am:
compile Checkpoint module
storage/maria/ha_maria.cc:
When ha_maria starts, do a recovery from last checkpoint.
Take a checkpoint when that recovery has ended and when ha_maria
shuts down cleanly.
storage/maria/ma_blockrec.c:
* even if my_sync() fails we have to my_close() (otherwise we leak
a descriptor)
* UNDO_ROW_PURGE is replaced by a simple CLR_END for UNDO_ROW_INSERT,
as promised in the old comment; it gives us skipping during the
UNDO phase.
storage/maria/ma_check.c:
All REDOs before create_rename_lsn are ignored by Recovery. So
create_rename_lsn must be set only after all data/index has been
flushed and forced to disk. We thus move write_log_record_for_repair()
to after _ma_flush_tables_files_after_repair().
storage/maria/ma_checkpoint.c:
Checkpoint module.
storage/maria/ma_checkpoint.h:
optional argument if caller wants a thread to periodically take
checkpoints and flush dirty pages.
storage/maria/ma_create.c:
* no need to init some vars as the initial bzero(share) takes care of this.
* update to new function's name
* even if we fail in my_sync() we have to my_close()
storage/maria/ma_extra.c:
Checkpoint reads share->last_version under intern_lock, so we make
maria_extra() update it under intern_lock. THR_LOCK_maria still needed
because of _ma_test_if_reopen().
storage/maria/ma_init.c:
destroy checkpoint module when Maria shuts down.
storage/maria/ma_loghandler.c:
* UNDO_ROW_PURGE gone (see ma_blockrec.c)
* we need to remember the LSN of the LOGREC_FILE_ID for a share,
because this LSN is needed into the checkpoint record (Recovery wants
to know the validity domain of an id->name mapping)
* translog_get_horizon_no_lock() needed for Checkpoint
* comment about failing assertion (Sanja knows)
* translog_init_reader_data() thought that translog_read_record_header_scan()
returns 0 in case of error, but 0 just means "0-length header".
* translog_assign_id_to_share() now needs the MARIA_HA because
LOGREC_FILE_ID uses a log-write hook.
* Verify that (de)assignment of share->id happens only under intern_lock,
as Checkpoint reads this id with intern_lock.
* translog_purge() can accept TRANSLOG_ADDRESS, not necessarily
a real LSN.
storage/maria/ma_loghandler.h:

storage/maria/ma_open.c:

WL#3071 Maria checkpoint
Finally this is the real checkpoint code.
It however exhibits unstabilities when a checkpoint runs concurrently
with data-modifying clients (table corruption, transaction log's
assertions) so for now a checkpoint is taken only at startup after
recovery and at shutdown, i.e. not in concurrent situations. Later
we will let it run periodically, as well as flush dirty pages
periodically (almost all needed code is there already, only pagecache
code is written but not committed).
WL#3072 Maria recovery
* replacing UNDO_ROW_PURGE with CLR_END; testing of those CLR_END via
ma_test2 which has INSERTs failing with duplicate keys.
* replaying of REDO_RENAME_TABLE
Now, off to test Recovery in ha_maria :)

* UNDO_ROW_PURGE is replaced by a simple CLR_END for UNDO_ROW_INSERT,
as promised in the old comment; it gives us skipping during the
UNDO phase.
storage/maria/ma_check.c:
All REDOs before create_rename_lsn are ignored by Recovery. So
create_rename_lsn must be set only after all data/index has been
flushed and forced to disk. We thus move write_log_record_for_repair()

WL#3071 Maria checkpoint
Finally this is the real checkpoint code.
It however exhibits unstabilities when a checkpoint runs concurrently
with data-modifying clients (table corruption, transaction log's
assertions) so for now a checkpoint is taken only at startup after
recovery and at shutdown, i.e. not in concurrent situations. Later
we will let it run periodically, as well as flush dirty pages
periodically (almost all needed code is there already, only pagecache
code is written but not committed).
WL#3072 Maria recovery
* replacing UNDO_ROW_PURGE with CLR_END; testing of those CLR_END via
ma_test2 which has INSERTs failing with duplicate keys.
* replaying of REDO_RENAME_TABLE
Now, off to test Recovery in ha_maria :)
BitKeeper/deleted/.del-ma_least_recently_dirtied.c:
Delete: storage/maria/ma_least_recently_dirtied.c
BitKeeper/deleted/.del-ma_least_recently_dirtied.h:
Delete: storage/maria/ma_least_recently_dirtied.h
storage/maria/Makefile.am:
compile Checkpoint module
storage/maria/ha_maria.cc:
When ha_maria starts, do a recovery from last checkpoint.
Take a checkpoint when that recovery has ended and when ha_maria
shuts down cleanly.
storage/maria/ma_blockrec.c:
* even if my_sync() fails we have to my_close() (otherwise we leak
a descriptor)
* UNDO_ROW_PURGE is replaced by a simple CLR_END for UNDO_ROW_INSERT,
as promised in the old comment; it gives us skipping during the
UNDO phase.
storage/maria/ma_check.c:
All REDOs before create_rename_lsn are ignored by Recovery. So
create_rename_lsn must be set only after all data/index has been
flushed and forced to disk. We thus move write_log_record_for_repair()
to after _ma_flush_tables_files_after_repair().
storage/maria/ma_checkpoint.c:
Checkpoint module.
storage/maria/ma_checkpoint.h:
optional argument if caller wants a thread to periodically take
checkpoints and flush dirty pages.
storage/maria/ma_create.c:
* no need to init some vars as the initial bzero(share) takes care of this.
* update to new function's name
* even if we fail in my_sync() we have to my_close()
storage/maria/ma_extra.c:
Checkpoint reads share->last_version under intern_lock, so we make
maria_extra() update it under intern_lock. THR_LOCK_maria still needed
because of _ma_test_if_reopen().
storage/maria/ma_init.c:
destroy checkpoint module when Maria shuts down.
storage/maria/ma_loghandler.c:
* UNDO_ROW_PURGE gone (see ma_blockrec.c)
* we need to remember the LSN of the LOGREC_FILE_ID for a share,
because this LSN is needed into the checkpoint record (Recovery wants
to know the validity domain of an id->name mapping)
* translog_get_horizon_no_lock() needed for Checkpoint
* comment about failing assertion (Sanja knows)
* translog_init_reader_data() thought that translog_read_record_header_scan()
returns 0 in case of error, but 0 just means "0-length header".
* translog_assign_id_to_share() now needs the MARIA_HA because
LOGREC_FILE_ID uses a log-write hook.
* Verify that (de)assignment of share->id happens only under intern_lock,
as Checkpoint reads this id with intern_lock.
* translog_purge() can accept TRANSLOG_ADDRESS, not necessarily
a real LSN.
storage/maria/ma_loghandler.h:
prototype updates
storage/maria/ma_open.c:
no need to initialize "res"
storage/maria/ma_pagecache.c:
When taking a checkpoint, we don't need to know the maximum rec_lsn
of dirty pages; this LSN was intended to be used in the two-checkpoint
rule, but last_checkpoint_lsn is as good.
4 bytes for stored_list_size is enough as PAGECACHE::blocks (number
of blocks which the pagecache can contain) is int.
storage/maria/ma_pagecache.h:
new prototype
storage/maria/ma_recovery.c:
* added replaying of REDO_RENAME_TABLE
* UNDO_ROW_PURGE gone (see ma_blockrec.c), replaced by CLR_END
* Recovery from the last checkpoint record now possible
* In new_table() we skip the table if the id->name mapping is older than
create_rename_lsn (mapping dates from lsn_of_file_id).
* in get_MARIA_HA_from_REDO_record() we skip the record
if the id->name mapping is newer than the record (can happen if processing
a record which is before the checkpoint record).
* parse_checkpoint_record() has to return a LSN, that's what caller expects
storage/maria/ma_rename.c:
new function's name; log end zeroes of tables' names (ease recovery)
storage/maria/ma_test2.c:
* equivalent of ma_test1's --test-undo added (named -u here).
* -t=1 now stops right after creating the table, so that
we can test undoing of INSERTs with duplicate keys (which tests the
CLR_END logged by _ma_write_abort_block_record()).
storage/maria/ma_test_recovery.expected:
Result of testing undoing of INSERTs with duplicate keys; there are
some differences in maria_chk -dvv but they are normal (removing
records does not shrink data/index file, does not put back the
"analyzed, optimized keys"(etc) index state.
storage/maria/ma_test_recovery:
Test undoing of INSERTs with duplicate keys, using ma_test2;
when such INSERT happens, it logs REDO_INSERT, UNDO_INSERT, REDO_DELETE,
CLR_END; we abort after that, and test that CLR_END causes recovery
to jump over UNDO_INSERT.

UNDO of rows now puts back all part of the row on their original pages and positions
Added variable _dbug_on_ to speed up execution when DBUG is not going to be used
Added --debug-on option to mysqld (to be able to turn of DBUG with --debug-on=0)
Fixed some bugs with 'non_flushable' marking of bitmap pages
Don't use 'non_flushable' marking of bitmap pages for not transactional tables
SHOW CREATE TABLE now shows if table was created with page checksums
Fixed a lot of bugs with BLOB handling in case of update/REDO and UNDO
More tests (especially for blobs) and DBUG_ASSERTS()
More readable output from maria_read_log and maria_chk
Fixed wrong shift that caused Maria to crash on files > 4G
Mark tables as crashed of REDO fails
dbug/dbug.c:
Changed to use my_bool (allowed me to remove some windows specific code)
Added variable _dbug_on_ to speed up execution when DBUG is not going to be used
Removed initialization of variables if not needed
include/my_dbug.h:
Use my_bool for some functions that was defined as BOOLEAN in dbug.c code
Added DBUGGER_ON/DEBUGGER_OFF to speed up execution when DBUG is not used

storage/maria/ha_maria.cc:
Store in create_info if page checksums are used (For SHOW CREATE TABLE)
storage/maria/ma_bitmap.c:
Added _ma_bitmap_wait_or_flush() to cause reader of bitmap pages to wait with reading until bitmap is flushed.
Use TAIL_PAGE_COUNT_MARKER for tail pages
Set 'sub_blocks' for and only for the head page or for the first extent of a blob. This is needed for store_extent_info() to be able to set START_EXTENT_BIT's
Don't allocate more than 0x3ffff pages in one extent (We need bit 0x4000 as a START_EXTENT_BIT)
Increase the calculated 'head_length' with the number of bytes used for extents.
Update row->space_on_head_page also in _ma_bitmap_find_new_place()
Make _ma_bitmap_get_page_bits() global. (Needed for UNDO handling)
Changed _ma_bitmap_flushable() to take MARIA_HA instead of MARIA_SHARE.

Added BLOCKUSED_USE_ORG_BITMAP handling also for tail pages.
Added more DBUG_ASSERT() to find possible errors in other code
Some code simplications by adding new local variables
storage/maria/ma_blockrec.c:
UNDO of rows now puts back all part of the row on their original pages and positions.
Changed UNDO of DELETE and UNDO of UPDATE to contain information about the original length of data on head block and also extent information
This changes a lot of logic as now an insert of a row on a page may happen to any position (and not just to the first or next free)
Use PAGE_COUNT to mark if an extent is the start of of a blob. (Needed for extent_to_bitmap_blocks())
Added check_directory() for checking that directroy entries are correct.
Added checking of row checksums when reading rows (with EXTRA_DEBUG)
Added make_space_for_directory() and extend_directory() for doing expansion of directory

Changed _ma_apply_undo_row_delete() and _ma_apply_undo_row_update() to put row in it's original position
Ensure allocation of tail blocks are of at least MIN_TAIL_SIZE.
Ensure we store pages in pinned pages even if read failed. (If not we will have pages pinned forever in page cache)
Write original extent information in UNDO entry, not compacted ones (we need position to tails!)
When setting BLOCKUSED_USED, don't clear other bits (we have to preserve BLOCKUSED_USE_ORG_BITMAP)
Fixed som bugs in directory handling
Fixed bug where we wrote wrong lsn to blob pages
Added separate blob_buffer for fixing bug when updating row that had char/varchar that spanned several pages and also had blobs
Ensure we call _ma_bitmap_flushable() also in case of errors
When doing an update, first delete old entries, then search in bitmap for where to put new information
Info->s -> share
Rowid -> rowid
More DBUG_ASSERT()
storage/maria/ma_blockrec.h:
Added START_EXTENT_BIT and TAIL_PAGE_COUNT_MARKER
Added _ma_bitmap_wait_or_flush() and _ma_bitmap_get_page_bits()
storage/maria/ma_check.c:
Don't write extra empty line if there is no deleted blocks
Ignore START_EXTENT_BIT's in page count

Disable 'dummy' checksumming of pages as this gave false warnings.
(Need to investigate if this is ever needed)
storage/maria/ma_pagecache.c:
Fixed wrong shift that caused Maria to crash on files > 4G
storage/maria/ma_recovery.c:
In case of errors, start writing on new line if we where in %## %## printing mode (Made errors more readable)
Changed global variable name from warnings -> recovery_warnings
Use MARIA_FILE_CREATE_RENAME_LSN_OFFSET instead of constant
Removed special handling of row position for deleted keys. Keys now always includes row positions
_ma_apply_undo_row_delete() now gets page and row position
Added check that we don't loop forever when handling undo's (in case of bug in undo chain)
Print name of failed REDO/UNDO
storage/maria/ma_recovery.h:
Removed old comment
storage/maria/ma_static.c:
Chaned version number of Maria files to not accidently use old ones (becasue of change of ordering of status variables)
storage/maria/ma_test2.c:
Added option -u to specify number of rows to update
Changed old option -u to be -A, as for ma_test1
Fixed bug in update of rows with blobs (before blobs was always reset to empty on update)
First created blob is now of max blob length to ensure we have at least one big blob in the table
storage/maria/ma_test_all.sh:
More tests
storage/maria/ma_test_recovery.expected:
Updated results
storage/maria/ma_test_recovery:
Changed tests to use bigger blobs (not just 1K)
Added new tests that tests recovery of update with blobs
Removed comparision of .MAD file as it's not guranteed that recovery from scratch gives identical data file as original update
(compact_page() may be called at different times during normal execution and during REDO)
storage/maria/ma_update.c:
Simplify code (changed * to if)
storage/maria/maria_chk.c:
Make output more readable
storage/maria/maria_def.h:
Changed 'changed' to int to prepare for more bits
Added 2 more bytes to status information
Added 'st_mara_row->min_length' for storing min length needed on head page

Fixed bug in update of rows with blobs (before blobs was always reset to empty on update)
storage/maria/ma_test_big.sh:
Testing of insert, update, delete, recovery and undo of rows with blobs
Thanks to the random-ness of ma_test2 this is likely to find most bugs in the row handling

WL#3072 - Maria Recovery
Bulk insert: don't log REDO/UNDO for rows, log one UNDO which will
truncate files; this is an optimization and a bugfix (table was left
half-repaired by crash).
Repair: mark table crashed-on-repair at start, bump skip_redo_lsn at start,
this is easier for recovery (tells it to skip old REDOs or even UNDO
phase) and user (tells it to repair) in case of crash, sync files
in the end.
Recovery skips missing or corrupted table and moves to next record
(in REDO or UNDO phase) to be more robust; warns if happens in UNDO phase.
Bugfix for UNDO_KEY_DELETE_WITH_ROOT (tested in ma_test_recovery)
and maria_enable_indexes().
Create missing bitmaps when needed (there can be more than one to create,
in rare cases), log a record for this.
include/myisamchk.h:
new flag: bulk insert repair mustn't bump create_rename_lsn
mysql-test/lib/mtr_report.pl:
skip normal warning in maria-recovery.test
mysql-test/r/maria-recovery.result:
result: crash before bulk insert is committed, causes proper rollback,
and crash right after OPTIMIZE replaces index file with new index file
leads to table marked corrupted and recovery not failing.
mysql-test/t/maria-recovery.test:
- can't check the table or it would commit the transaction,
but check is made after recovery.
- test of crash before bulk-insert-with-repair is committed
(to see if it is rolled back), and of crash after OPTIMIZE has replaced
index file but not finished all operations (to see if recovery fails -
it used to assert when trying to execute an old REDO on the new
index).
storage/maria/CMakeLists.txt:
new file
storage/maria/Makefile.am:
new file
storage/maria/ha_maria.cc:
- If bulk insert on a transactional table using an index repair:
table is initially empty, so don't log REDO/UNDO for data rows
(optimization), just log an UNDO_BULK_INSERT_WITH_REPAIR
which will, if executed, empty the data and index file. Re-enable
logging in end_bulk_insert().
- write log record for repair operation only after it's fully done,
index sort including (maria_repair*() used to write the log record).
- Adding back file->trn=NULL which was removed by mistake earlier.
storage/maria/ha_maria.h:
new member (see ha_maria.cc)
storage/maria/ma_bitmap.c:
Functions to create missing bitmaps:
- one function which creates missing bitmaps in page cache, except
the missing one with max offset which it does not put into page cache
as it will be modified very soon.
- one function which the one above calls, and creates bitmaps in page
cache
- one function to execute REDO_BITMAP_NEW_PAGE which uses the second
one above.
storage/maria/ma_blockrec.c:
- when logging REDO_DELETE_ALL, not only 'records' and 'checksum'
has to be reset under log's mutex.
- execution of REDO_INSERT_ROW_BLOBS now checks the dirty pages' list
- execution of UNDO_BULK_INSERT_WITH_REPAIR
storage/maria/ma_blockrec.h:
new functions
storage/maria/ma_check.c:
- table-flush-before-repair is moved to a separate function reused
by maria_sort_index(); syncing is added
- maria_repair() is allowed to re-enable logging only if it is the one
which disabled it.
- "_ma_flush_table_files_after_repair" was a bad name, it's not after
repair now, and it should not sync as we do more changes to the files
shortly after (sync is postponed to when writing the log record)
- REDO_REPAIR record should be written only after all repair
operations (in particular after sorting index in ha_mara::repair())
- close to the end of repair by sort, flushing of pages must happen
also in the non-quick case, to prepare for the sync at end.
- in parallel repair, some page flushes are not needed as done
by initialize_variables_for_repair().
storage/maria/ma_create.c:
Update skip_redo_lsn, create_rename_lsn optionally.
storage/maria/ma_delete_all.c:
Need to sync files at end of maria_delete_all_rows(), if transactional.
storage/maria/ma_extra.c:
During repair, we sometimes call _ma_flush_table_files() (via
_ma_flush_table_files_before_swap()) while there is a WRITE_CACHE.
storage/maria/ma_key_recover.c:
- when we see CLR_END for UNDO_BULK_INSERT_WITH_REPAIR, re-enable
indices.
- fixing bug: _ma_apply_undo_key_delete() parsed UNDO_KEY_DELETE_WITH_ROOT
wrongly, leading to recovery failure
storage/maria/ma_key_recover.h:
new prototype
storage/maria/ma_locking.c:
DBUG_VOID_RETURN missing
storage/maria/ma_loghandler.c:
UNDO for bulk insert with repair, and REDO for creating bitmaps.
LOGREC_FIRST_FREE to not have to change the for() every time we
add a new record type.
storage/maria/ma_loghandler.h:
new UNDO and REDO
storage/maria/ma_open.c:
Move share.kfile.file=kfile up a bit, so that _ma_update_state_lsns()
can get its value, this fixes a bug where LSN_REPAIRED_BY_MARIA_CHK
was not corrected on disk by maria_open().
Store skip_redo_lsn in index' header.
maria_enable_indexes() had a bug for BLOCK_RECORD, where an empty
file has one page, not 0 bytes.
storage/maria/ma_recovery.c:
- Skip a corrupted, missing, or repaired-with-maria_chk, table in
recovery: don't fail, just go to next REDO or UNDO; but if an UNDO
is skipped in UNDO phase we issue warnings.
- Skip REDO|UNDO in REDO phase if <skip_redo_lsn.
- If UNDO phase fails, delete transactions to not make trnman
assert.
- Update skip_redo_lsn when playing REDO_CREATE_TABLE
- Don't record UNDOs for old transactions which we don't know (long_trid==0)
- Bugfix for UNDO_KEY_DELETE_WITH_ROOT (see ma_key_recover.c)
- Execution of UNDO_BULK_INSERT_WITH_REPAIR
- Don't try to find a page number in REDO_DELETE_ALL
- Pieces moved to ma_recovery_util.c
storage/maria/ma_rename.c:
name change
storage/maria/ma_static.c:
I modified layout of the index' header (inserted skip_redo_lsn in its middle)
storage/maria/ma_test2.c:
allow breaking the test towards the end, tests execution of
UNDO_KEY_DELETE_WITH_ROOT
storage/maria/ma_test_recovery.expected:
6 as testflag instead of 4
storage/maria/ma_test_recovery:
Increase the amount of rollback work to do when testing recovery
with ma_test2; this reproduces the UNDO_KEY_DELETE_WITH_ROOT bug.
storage/maria/maria_chk.c:
skip_redo_lsn should be updated too, for consistency.
Write a REDO_REPAIR after all operations (including sort-records)
have been done.
No reason to flush blocks after maria_chk_data_link() and
maria_sort_records(), there is maria_close() in the end.
write_log_record() is a function, to not clutter maria_chk().
storage/maria/maria_def.h:
New member skip_redo_lsn in the state, and comments
storage/maria/maria_pack.c:
skip_redo_lsn should be updated too, for consistency
storage/maria/ma_recovery_util.c:
_ma_redo_not_needed_for_page(), defined in ma_recovery.c, is needed
by ma_blockrec.c; this causes link issues, resolved by putting
_ma_redo_not_needed_for_page() into a new file (so that it is not
in the same file as repair-related objects of ma_recovery.c).
storage/maria/ma_recovery_util.h:
new file

Use PAGE_COUNT to mark if an extent is the start of of a blob. (Needed for extent_to_bitmap_blocks())
Added check_directory() for checking that directroy entries are correct.
Added checking of row checksums when reading rows (with EXTRA_DEBUG)
Added make_space_for_directory() and extend_directory() for doing expansion of directory

Fixed som bugs in directory handling
Fixed bug where we wrote wrong lsn to blob pages
Added separate blob_buffer for fixing bug when updating row that had char/varchar that spanned several pages and also had blobs

Updated results
storage/maria/ma_test_recovery:
Changed tests to use bigger blobs (not just 1K)

Added --debug-on option to mysqld (to be able to turn of DBUG with --debug-on=0)
Fixed some bugs with 'non_flushable' marking of bitmap pages
Don't use 'non_flushable' marking of bitmap pages for not transactional tables
SHOW CREATE TABLE now shows if table was created with page checksums
Fixed a lot of bugs with BLOB handling in case of update/REDO and UNDO
More tests (especially for blobs) and DBUG_ASSERTS()
More readable output from maria_read_log and maria_chk
Fixed wrong shift that caused Maria to crash on files > 4G
Mark tables as crashed of REDO fails
dbug/dbug.c:
Changed to use my_bool (allowed me to remove some windows specific code)
Added variable _dbug_on_ to speed up execution when DBUG is not going to be used
Removed initialization of variables if not needed

Store in create_info if page checksums are used (For SHOW CREATE TABLE)
storage/maria/ma_bitmap.c:
Added _ma_bitmap_wait_or_flush() to cause reader of bitmap pages to wait with reading until bitmap is flushed.
Use TAIL_PAGE_COUNT_MARKER for tail pages
Set 'sub_blocks' for and only for the head page or for the first extent of a blob. This is needed for store_extent_info() to be able to set START_EXTENT_BIT's
Don't allocate more than 0x3ffff pages in one extent (We need bit 0x4000 as a START_EXTENT_BIT)
Increase the calculated 'head_length' with the number of bytes used for extents.
Update row->space_on_head_page also in _ma_bitmap_find_new_place()

Use PAGE_COUNT to mark if an extent is the start of of a blob. (Needed for extent_to_bitmap_blocks())
Added check_directory() for checking that directroy entries are correct.
Added checking of row checksums when reading rows (with EXTRA_DEBUG)
Added make_space_for_directory() and extend_directory() for doing expansion of directory

Ensure allocation of tail blocks are of at least MIN_TAIL_SIZE.
Ensure we store pages in pinned pages even if read failed. (If not we will have pages pinned forever in page cache)
Write original extent information in UNDO entry, not compacted ones (we need position to tails!)
When setting BLOCKUSED_USED, don't clear other bits (we have to preserve BLOCKUSED_USE_ORG_BITMAP)
Fixed som bugs in directory handling
Fixed bug where we wrote wrong lsn to blob pages
Added separate blob_buffer for fixing bug when updating row that had char/varchar that spanned several pages and also had blobs
Ensure we call _ma_bitmap_flushable() also in case of errors
When doing an update, first delete old entries, then search in bitmap for where to put new information
Info->s -> share
Rowid -> rowid

Added option -u to specify number of rows to update
Changed old option -u to be -A, as for ma_test1

Updated results
storage/maria/ma_test_recovery:
Changed tests to use bigger blobs (not just 1K)

WL#3072 Maria Recovery
misc fixes of execution of UNDOs in the UNDO phase:
- into the CLR_END, store the LSN of the _previous_ UNDO (we debated
what was best, so far we're going with "previous"; later we can change
to "current" if needed), and store the type of record which is being
undone (needed to know how to update state.records when we see the
CLR_END during the REDO phase).
- declaring all UNDOs and CLR_END as "compressed"
- when executing an UNDO in the UNDO phase, state.records is updated
as a hook when writing CLR_END (needed for "recovery of the state"),
and so is trn->undo_lsn (needed for when we have checkpoints).
- bugfix (execution of UNDO_ROW_DELETE didn't store the correct checksum
into the re-inserted row, maria_chk -r thus threw the row away).
- modifications of ma_test1: where to stop is now driven by --testflag;
--test-undo just tells how to stop (flush data, flush log, nothing).
- ma_test_recovery: testing of the UNDO phase, more testing of the
REDO phase, identification of a bug.
storage/maria/ma_blockrec.c:
- bugfix: execution of UNDO_ROW_DELETE didn't store the correct
checksum into the row (leading to "maria_chk -r" eliminating the
re-inserted row, net effect was that rollback appeared to have
rolled back no deletion). Reason was that write_block_record() used
info->cur_row.checksum, while "row" can be != &info->cur_row
(case of UNDO_ROW_DELETE). After fixing this, problems with
_ma_update_block_record() appeared; indeed checksum was computed
by allocate_and_write_block_record() while _ma_update_block_record()
directly calls write_block_record(). Solution is to compute checksum
in write_block_record() instead.
- when executing an UNDO, we now pass the LSN of the _previous_ UNDO
to block_format functions. This LSN can be 0 (if the being-executed UNDO
was the transaction's first UNDO), so "undo_lsn==0" cannot work
anymore to indicate "this is not UNDO work". Using undo_lsn==LSN_ERROR
instead (this is an impossible LSN).
- store into CLR_END the type of log record which was undone
(INSERT/UPDATE/DELETE); needed for Recovery to know if/how it has
to update state.records if it sees this CLR_END in the REDO phase.
- when writing the CLR_END in _ma_apply_undo_row_insert(),
the place to store file's id is log_data+LSN_STORE_SIZE.
- in _ma_apply_undo_row_insert(), the records-- is moved
to a hook when writing the CLR_END (this way it is under log's mutex
which is needed for "recovery of the state")
storage/maria/ma_loghandler.c:
- all UNDOs, and CLR_END, start with the LSN of another UNDO; so
we can declare them "compressed".
- write_hook_for_clr_end() to set trn->undo_lsn (to the previous
UNDO's LSN) under log's lock (like UNDOs set trn->undo_lsn under log's
lock), and also update, if appropriate, state.records.
- reset share->id to 0 when deassigning; not useful for now but
sounds logical.
storage/maria/ma_recovery.c:
- if no table is found for a REDO, it's not an error; for an UNDO, it is
- in the REDO phase, when we see a CLR_END we must update trn->undo_lsn
and sometimes state.records.
- in the UNDO phase, when we execute an UNDO_ROW_INSERT:
* update trn->undo_lsn only after executing the record
* store the _previous_ undo_lsn into the CLR_END
- at the end of the REDO phase, when we recreate TRN objects, they
have already their long id in the log (either via a
LOGREC_LONG_TRANSACTION_ID, or in a checkpoint record), don't write
a new, useless LOGREC_LONG_TRANSACTION_ID for them.
storage/maria/ma_test1.c:
* where to stop execution is now driven by --testflag and not --test-undo
(ma_test2 already has --testflag for the same purpose). This allows
us to do a clean stop (with commit) at any point.
* --test-undo=# tells how to abort (flush all pages (which implies
flushing log) or only log or nothing); all such "ways of crashing"
are tested in ma_test_recovery
storage/maria/ma_test_recovery:
* Testing execution of UNDOs, with and without BLOBs.
* Testing idempotency of REDOs.
* See @todo for a probable bug with BLOBs.
* maria_chk -rq instead of -r, as with -q it nicely stops on any
problem in the data file (like the checksum bug see comment of
ma_blockrec.c).
* Testing if log was written by UNDO phase (often expected),
not written by REDO phase (always expected).
* Less output on the screen, compares with expected output in the end.
* some shell thingies like "set --" and $# are courtesy of
Danny and Pekka.
storage/maria/maria_read_log.c:
when only displaying the records, don't do an UNDO phase
storage/maria/ma_test_recovery.expected:
This is the expected output of a great part of ma_test_recovery.
ma_test_recovery compares its output to the expected output
and tells if different.
If we look at this file it mentions differences in checksum
(normal, it's not recovered yet) and in records count
(getting a correct records' count when recovery starts on an
already existing table, like when testing rollback,
is coded but not yet pushed).

Changed _ma_apply_undo_row_delete() and _ma_apply_undo_row_update() to put row in it's original position
Ensure allocation of tail blocks are of at least MIN_TAIL_SIZE.
Ensure we store pages in pinned pages even if read failed. (If not we will have pages pinned forever in page cache)
Write original extent information in UNDO entry, not compacted ones (we need position to tails!)
When setting BLOCKUSED_USED, don't clear other bits (we have to preserve BLOCKUSED_USE_ORG_BITMAP)
Fixed som bugs in directory handling

Updated results
storage/maria/ma_test_recovery:
Changed tests to use bigger blobs (not just 1K)

WL#3072 Maria Recovery
misc fixes of execution of UNDOs in the UNDO phase:
- into the CLR_END, store the LSN of the _previous_ UNDO (we debated
what was best, so far we're going with "previous"; later we can change
to "current" if needed), and store the type of record which is being
undone (needed to know how to update state.records when we see the
CLR_END during the REDO phase).
- declaring all UNDOs and CLR_END as "compressed"
- when executing an UNDO in the UNDO phase, state.records is updated
as a hook when writing CLR_END (needed for "recovery of the state"),
and so is trn->undo_lsn (needed for when we have checkpoints).
- bugfix (execution of UNDO_ROW_DELETE didn't store the correct checksum
into the re-inserted row, maria_chk -r thus threw the row away).
- modifications of ma_test1: where to stop is now driven by --testflag;
--test-undo just tells how to stop (flush data, flush log, nothing).
- ma_test_recovery: testing of the UNDO phase, more testing of the
REDO phase, identification of a bug.
storage/maria/ma_blockrec.c:
- bugfix: execution of UNDO_ROW_DELETE didn't store the correct
checksum into the row (leading to "maria_chk -r" eliminating the
re-inserted row, net effect was that rollback appeared to have
rolled back no deletion). Reason was that write_block_record() used
info->cur_row.checksum, while "row" can be != &info->cur_row
(case of UNDO_ROW_DELETE). After fixing this, problems with
_ma_update_block_record() appeared; indeed checksum was computed
by allocate_and_write_block_record() while _ma_update_block_record()
directly calls write_block_record(). Solution is to compute checksum
in write_block_record() instead.
- when executing an UNDO, we now pass the LSN of the _previous_ UNDO
to block_format functions. This LSN can be 0 (if the being-executed UNDO
was the transaction's first UNDO), so "undo_lsn==0" cannot work
anymore to indicate "this is not UNDO work". Using undo_lsn==LSN_ERROR
instead (this is an impossible LSN).
- store into CLR_END the type of log record which was undone
(INSERT/UPDATE/DELETE); needed for Recovery to know if/how it has
to update state.records if it sees this CLR_END in the REDO phase.
- when writing the CLR_END in _ma_apply_undo_row_insert(),
the place to store file's id is log_data+LSN_STORE_SIZE.
- in _ma_apply_undo_row_insert(), the records-- is moved
to a hook when writing the CLR_END (this way it is under log's mutex
which is needed for "recovery of the state")
storage/maria/ma_loghandler.c:
- all UNDOs, and CLR_END, start with the LSN of another UNDO; so
we can declare them "compressed".
- write_hook_for_clr_end() to set trn->undo_lsn (to the previous
UNDO's LSN) under log's lock (like UNDOs set trn->undo_lsn under log's
lock), and also update, if appropriate, state.records.
- reset share->id to 0 when deassigning; not useful for now but
sounds logical.
storage/maria/ma_recovery.c:
- if no table is found for a REDO, it's not an error; for an UNDO, it is
- in the REDO phase, when we see a CLR_END we must update trn->undo_lsn
and sometimes state.records.
- in the UNDO phase, when we execute an UNDO_ROW_INSERT:
* update trn->undo_lsn only after executing the record
* store the _previous_ undo_lsn into the CLR_END
- at the end of the REDO phase, when we recreate TRN objects, they
have already their long id in the log (either via a
LOGREC_LONG_TRANSACTION_ID, or in a checkpoint record), don't write
a new, useless LOGREC_LONG_TRANSACTION_ID for them.
storage/maria/ma_test1.c:
* where to stop execution is now driven by --testflag and not --test-undo
(ma_test2 already has --testflag for the same purpose). This allows
us to do a clean stop (with commit) at any point.
* --test-undo=# tells how to abort (flush all pages (which implies
flushing log) or only log or nothing); all such "ways of crashing"
are tested in ma_test_recovery
storage/maria/ma_test_recovery:
* Testing execution of UNDOs, with and without BLOBs.
* Testing idempotency of REDOs.
* See @todo for a probable bug with BLOBs.
* maria_chk -rq instead of -r, as with -q it nicely stops on any
problem in the data file (like the checksum bug see comment of
ma_blockrec.c).
* Testing if log was written by UNDO phase (often expected),
not written by REDO phase (always expected).
* Less output on the screen, compares with expected output in the end.
* some shell thingies like "set --" and $# are courtesy of
Danny and Pekka.
storage/maria/maria_read_log.c:
when only displaying the records, don't do an UNDO phase
storage/maria/ma_test_recovery.expected:
This is the expected output of a great part of ma_test_recovery.
ma_test_recovery compares its output to the expected output
and tells if different.
If we look at this file it mentions differences in checksum
(normal, it's not recovered yet) and in records count
(getting a correct records' count when recovery starts on an
already existing table, like when testing rollback,
is coded but not yet pushed).

Ensure allocation of tail blocks are of at least MIN_TAIL_SIZE.
Ensure we store pages in pinned pages even if read failed. (If not we will have pages pinned forever in page cache)
Write original extent information in UNDO entry, not compacted ones (we need position to tails!)
When setting BLOCKUSED_USED, don't clear other bits (we have to preserve BLOCKUSED_USE_ORG_BITMAP)
Fixed som bugs in directory handling
Fixed bug where we wrote wrong lsn to blob pages
Added separate blob_buffer for fixing bug when updating row that had char/varchar that spanned several pages and also had blobs

Updated results
storage/maria/ma_test_recovery:
Changed tests to use bigger blobs (not just 1K)

Fixed some bugs with 'non_flushable' marking of bitmap pages
Don't use 'non_flushable' marking of bitmap pages for not transactional tables
SHOW CREATE TABLE now shows if table was created with page checksums
Fixed a lot of bugs with BLOB handling in case of update/REDO and UNDO
More tests (especially for blobs) and DBUG_ASSERTS()
More readable output from maria_read_log and maria_chk
Fixed wrong shift that caused Maria to crash on files > 4G
Mark tables as crashed of REDO fails
dbug/dbug.c:
Changed to use my_bool (allowed me to remove some windows specific code)
Added variable _dbug_on_ to speed up execution when DBUG is not going to be used
Removed initialization of variables if not needed
include/my_dbug.h:

storage/maria/Makefile.am:
Added ma_test_big.sh
storage/maria/ha_maria.cc:
Store in create_info if page checksums are used (For SHOW CREATE TABLE)
storage/maria/ma_bitmap.c:
Added _ma_bitmap_wait_or_flush() to cause reader of bitmap pages to wait with reading until bitmap is flushed.
Use TAIL_PAGE_COUNT_MARKER for tail pages
Set 'sub_blocks' for and only for the head page or for the first extent of a blob. This is needed for store_extent_info() to be able to set START_EXTENT_BIT's
Don't allocate more than 0x3ffff pages in one extent (We need bit 0x4000 as a START_EXTENT_BIT)
Increase the calculated 'head_length' with the number of bytes used for extents.
Update row->space_on_head_page also in _ma_bitmap_find_new_place()
Make _ma_bitmap_get_page_bits() global. (Needed for UNDO handling)
Changed _ma_bitmap_flushable() to take MARIA_HA instead of MARIA_SHARE.
This was needed to be able to mark the handler if we had a 'non_flushable' call pending or not.
Don't use 'non_flushable' marking of bitmap pages for not transactional tables.
Added BLOCKUSED_USE_ORG_BITMAP handling also for tail pages.
Added more DBUG_ASSERT() to find possible errors in other code
Some code simplications by adding new local variables
storage/maria/ma_blockrec.c:
UNDO of rows now puts back all part of the row on their original pages and positions.
Changed UNDO of DELETE and UNDO of UPDATE to contain information about the original length of data on head block and also extent information
This changes a lot of logic as now an insert of a row on a page may happen to any position (and not just to the first or next free)
Use PAGE_COUNT to mark if an extent is the start of of a blob. (Needed for extent_to_bitmap_blocks())
Added check_directory() for checking that directroy entries are correct.
Added checking of row checksums when reading rows (with EXTRA_DEBUG)
Added make_space_for_directory() and extend_directory() for doing expansion of directory
Added get_rowpos_in_head_or_tail_page() to be able to store head/tail on original position in UNDO
Added extent_to_bitmap_blocks() to be able to generate original bitmap blocks from UNDO entry
Added _ma_update_at_original_place() for UNDO of DELETES
Added row->min_length to hold minmum required space needed on head page
Changed find_free_position() to use make_space_for_directory()
Changed make_empty_page() to allow optional creation of directory entry
Changed delete_head_or_tail() and _ma_apply_undo_row_isnert() to not copy pagecache block (speed optimization)
Changed _ma_apply_redo_insert_row_head_or_tail() to be able to insert new row at any position on 'new' page
Changed _ma_apply_undo_row_delete() and _ma_apply_undo_row_update() to put row in it's original position
Ensure allocation of tail blocks are of at least MIN_TAIL_SIZE.
Ensure we store pages in pinned pages even if read failed. (If not we will have pages pinned forever in page cache)
Write original extent information in UNDO entry, not compacted ones (we need position to tails!)
When setting BLOCKUSED_USED, don't clear other bits (we have to preserve BLOCKUSED_USE_ORG_BITMAP)
Fixed som bugs in directory handling
Fixed bug where we wrote wrong lsn to blob pages
Added separate blob_buffer for fixing bug when updating row that had char/varchar that spanned several pages and also had blobs
Ensure we call _ma_bitmap_flushable() also in case of errors
When doing an update, first delete old entries, then search in bitmap for where to put new information

Update row->space_on_head_page also in _ma_bitmap_find_new_place()
Make _ma_bitmap_get_page_bits() global. (Needed for UNDO handling)
Changed _ma_bitmap_flushable() to take MARIA_HA instead of MARIA_SHARE.
This was needed to be able to mark the handler if we had a 'non_flushable' call pending or not.
Don't use 'non_flushable' marking of bitmap pages for not transactional tables.
Added BLOCKUSED_USE_ORG_BITMAP handling also for tail pages.
Added more DBUG_ASSERT() to find possible errors in other code
Some code simplications by adding new local variables
storage/maria/ma_blockrec.c:
UNDO of rows now puts back all part of the row on their original pages and positions.
Changed UNDO of DELETE and UNDO of UPDATE to contain information about the original length of data on head block and also extent information
This changes a lot of logic as now an insert of a row on a page may happen to any position (and not just to the first or next free)
Use PAGE_COUNT to mark if an extent is the start of of a blob. (Needed for extent_to_bitmap_blocks())
Added check_directory() for checking that directroy entries are correct.
Added checking of row checksums when reading rows (with EXTRA_DEBUG)
Added make_space_for_directory() and extend_directory() for doing expansion of directory
Added get_rowpos_in_head_or_tail_page() to be able to store head/tail on original position in UNDO

Changed delete_head_or_tail() and _ma_apply_undo_row_isnert() to not copy pagecache block (speed optimization)
Changed _ma_apply_redo_insert_row_head_or_tail() to be able to insert new row at any position on 'new' page
Changed _ma_apply_undo_row_delete() and _ma_apply_undo_row_update() to put row in it's original position
Ensure allocation of tail blocks are of at least MIN_TAIL_SIZE.
Ensure we store pages in pinned pages even if read failed. (If not we will have pages pinned forever in page cache)
Write original extent information in UNDO entry, not compacted ones (we need position to tails!)
When setting BLOCKUSED_USED, don't clear other bits (we have to preserve BLOCKUSED_USE_ORG_BITMAP)
Fixed som bugs in directory handling
Fixed bug where we wrote wrong lsn to blob pages
Added separate blob_buffer for fixing bug when updating row that had char/varchar that spanned several pages and also had blobs
Ensure we call _ma_bitmap_flushable() also in case of errors
When doing an update, first delete old entries, then search in bitmap for where to put new information

Removed special handling of row position for deleted keys. Keys now always includes row positions
_ma_apply_undo_row_delete() now gets page and row position
Added check that we don't loop forever when handling undo's (in case of bug in undo chain)
Print name of failed REDO/UNDO
storage/maria/ma_recovery.h:
Removed old comment
storage/maria/ma_static.c:
Chaned version number of Maria files to not accidently use old ones (becasue of change of ordering of status variables)
storage/maria/ma_test2.c:
Added option -u to specify number of rows to update
Changed old option -u to be -A, as for ma_test1

Updated results
storage/maria/ma_test_recovery:

Fixed wrong shift that caused Maria to crash on files > 4G
Mark tables as crashed of REDO fails
dbug/dbug.c:
Changed to use my_bool (allowed me to remove some windows specific code)
Added variable _dbug_on_ to speed up execution when DBUG is not going to be used
Removed initialization of variables if not needed
include/my_dbug.h:
Use my_bool for some functions that was defined as BOOLEAN in dbug.c code
Added DBUGGER_ON/DEBUGGER_OFF to speed up execution when DBUG is not used
include/my_global.h:
Define my_bool early
Increase MY_HOW_OFTEN_TO_WRITE as computers are now faster than 10 years ago
mysql-test/mysql-test-run.pl:
Added debug-on=0 to speed up tests
mysql-test/r/maria-recovery.result:
Added new test by Guilhem to test if UNDO_ROW_DELETE preserves rowid
mysql-test/r/maria.result:
Added testing of page checksums
mysql-test/t/crash_commit_before-master.opt:
Added --debug-on as test require DBUG to work
mysql-test/t/maria-recovery-bitmap-master.opt:
Added --debug-on as test require DBUG to work
mysql-test/t/maria-recovery-master.opt:
Added --debug-on as test require DBUG to work
mysql-test/t/maria-recovery.test:
Added new test by Guilhem to test if UNDO_ROW_DELETE preserves rowid
mysql-test/t/maria.test:
Added testing of page checksums
sql/mysqld.cc:
Added --debug-on option (to be able to turn of DBUG with --debug-on=0)
Indentation fixes
Removed end spaces
sql/sql_show.cc:
Allow update_create_info() to inform MySQL if PACK_KEYS, NO_PACK_KEYS, CHECKSUM, PAGE_CHECKSUM or DELAY_KEY_WRITE is used
storage/maria/Makefile.am:
Added ma_test_big.sh
storage/maria/ha_maria.cc:
Store in create_info if page checksums are used (For SHOW CREATE TABLE)
storage/maria/ma_bitmap.c:
Added _ma_bitmap_wait_or_flush() to cause reader of bitmap pages to wait with reading until bitmap is flushed.
Use TAIL_PAGE_COUNT_MARKER for tail pages
Set 'sub_blocks' for and only for the head page or for the first extent of a blob. This is needed for store_extent_info() to be able to set START_EXTENT_BIT's
Don't allocate more than 0x3ffff pages in one extent (We need bit 0x4000 as a START_EXTENT_BIT)
Increase the calculated 'head_length' with the number of bytes used for extents.
Update row->space_on_head_page also in _ma_bitmap_find_new_place()
Make _ma_bitmap_get_page_bits() global. (Needed for UNDO handling)
Changed _ma_bitmap_flushable() to take MARIA_HA instead of MARIA_SHARE.
This was needed to be able to mark the handler if we had a 'non_flushable' call pending or not.
Don't use 'non_flushable' marking of bitmap pages for not transactional tables.
Added BLOCKUSED_USE_ORG_BITMAP handling also for tail pages.
Added more DBUG_ASSERT() to find possible errors in other code
Some code simplications by adding new local variables
storage/maria/ma_blockrec.c:
UNDO of rows now puts back all part of the row on their original pages and positions.
Changed UNDO of DELETE and UNDO of UPDATE to contain information about the original length of data on head block and also extent information
This changes a lot of logic as now an insert of a row on a page may happen to any position (and not just to the first or next free)
Use PAGE_COUNT to mark if an extent is the start of of a blob. (Needed for extent_to_bitmap_blocks())
Added check_directory() for checking that directroy entries are correct.
Added checking of row checksums when reading rows (with EXTRA_DEBUG)
Added make_space_for_directory() and extend_directory() for doing expansion of directory
Added get_rowpos_in_head_or_tail_page() to be able to store head/tail on original position in UNDO
Added extent_to_bitmap_blocks() to be able to generate original bitmap blocks from UNDO entry
Added _ma_update_at_original_place() for UNDO of DELETES
Added row->min_length to hold minmum required space needed on head page
Changed find_free_position() to use make_space_for_directory()
Changed make_empty_page() to allow optional creation of directory entry
Changed delete_head_or_tail() and _ma_apply_undo_row_isnert() to not copy pagecache block (speed optimization)
Changed _ma_apply_redo_insert_row_head_or_tail() to be able to insert new row at any position on 'new' page
Changed _ma_apply_undo_row_delete() and _ma_apply_undo_row_update() to put row in it's original position
Ensure allocation of tail blocks are of at least MIN_TAIL_SIZE.
Ensure we store pages in pinned pages even if read failed. (If not we will have pages pinned forever in page cache)
Write original extent information in UNDO entry, not compacted ones (we need position to tails!)
When setting BLOCKUSED_USED, don't clear other bits (we have to preserve BLOCKUSED_USE_ORG_BITMAP)
Fixed som bugs in directory handling
Fixed bug where we wrote wrong lsn to blob pages
Added separate blob_buffer for fixing bug when updating row that had char/varchar that spanned several pages and also had blobs
Ensure we call _ma_bitmap_flushable() also in case of errors
When doing an update, first delete old entries, then search in bitmap for where to put new information
Info->s -> share
Rowid -> rowid
More DBUG_ASSERT()
storage/maria/ma_blockrec.h:
Added START_EXTENT_BIT and TAIL_PAGE_COUNT_MARKER
Added _ma_bitmap_wait_or_flush() and _ma_bitmap_get_page_bits()
storage/maria/ma_check.c:
Don't write extra empty line if there is no deleted blocks
Ignore START_EXTENT_BIT's in page count
Call _ma_fast_unlock_key_del() to free key_del link
storage/maria/ma_close.c:
Ensure that used_key_del is 0. (If not, someone forgot to call _ma_unlock_key_del())
storage/maria/ma_create.c:
Changed constant to macro
storage/maria/ma_delete.c:
For deleted keys, log also position to row
storage/maria/ma_extra.c:
Release blob buffer at maria_reset() if bigger than MARIA_SMALL_BLOB_BUFFER
storage/maria/ma_key_recover.c:
Added bzero() of LSN that confused paged cache in case of uninitialized block
Mark file crashed if applying of index changes fails
Added calls to _ma_fast_unlock_key_del() for protection of shared key_del link.
storage/maria/ma_locking.c:
Added usage of MARIA_FILE_OPEN_COUNT_OFFSET
Added _ma_mark_file_crashed()
storage/maria/ma_loghandler.c:
Fixed bug where we logged uninitialized memory
storage/maria/ma_open.c:
Moved state->changed to be at start of state info on disk to allow one to easly mark files as crashed
storage/maria/ma_page.c:
Disable 'dummy' checksumming of pages as this gave false warnings.
(Need to investigate if this is ever needed)
storage/maria/ma_pagecache.c:
Fixed wrong shift that caused Maria to crash on files > 4G
storage/maria/ma_recovery.c:
In case of errors, start writing on new line if we where in %## %## printing mode (Made errors more readable)
Changed global variable name from warnings -> recovery_warnings
Use MARIA_FILE_CREATE_RENAME_LSN_OFFSET instead of constant
Removed special handling of row position for deleted keys. Keys now always includes row positions
_ma_apply_undo_row_delete() now gets page and row position
Added check that we don't loop forever when handling undo's (in case of bug in undo chain)
Print name of failed REDO/UNDO
storage/maria/ma_recovery.h:
Removed old comment
storage/maria/ma_static.c:
Chaned version number of Maria files to not accidently use old ones (becasue of change of ordering of status variables)
storage/maria/ma_test2.c:
Added option -u to specify number of rows to update
Changed old option -u to be -A, as for ma_test1
Fixed bug in update of rows with blobs (before blobs was always reset to empty on update)
First created blob is now of max blob length to ensure we have at least one big blob in the table
storage/maria/ma_test_all.sh:
More tests
storage/maria/ma_test_recovery.expected:
Updated results
storage/maria/ma_test_recovery:
Changed tests to use bigger blobs (not just 1K)
Added new tests that tests recovery of update with blobs
Removed comparision of .MAD file as it's not guranteed that recovery from scratch gives identical data file as original update
(compact_page() may be called at different times during normal execution and during REDO)
storage/maria/ma_update.c:
Simplify code (changed * to if)
storage/maria/maria_chk.c:
Make output more readable
storage/maria/maria_def.h:
Changed 'changed' to int to prepare for more bits
Added 2 more bytes to status information
Added 'st_mara_row->min_length' for storing min length needed on head page
Added 'st_mara_handler->blob_buff & blob_buff_size' for storing blobs
Moved all tunning parameters into one block
Added MARIA_SMALL_BLOB_BUFFER
Added _ma_mark_file_crashed()
storage/myisam/mi_test2.c:
Fixed bug in update of rows with blobs (before blobs was always reset to empty on update)
storage/maria/ma_test_big.sh:
Testing of insert, update, delete, recovery and undo of rows with blobs
Thanks to the random-ness of ma_test2 this is likely to find most bugs in the row handling

WL#3072 - Maria Recovery
Bulk insert: don't log REDO/UNDO for rows, log one UNDO which will
truncate files; this is an optimization and a bugfix (table was left
half-repaired by crash).
Repair: mark table crashed-on-repair at start, bump skip_redo_lsn at start,
this is easier for recovery (tells it to skip old REDOs or even UNDO
phase) and user (tells it to repair) in case of crash, sync files
in the end.
Recovery skips missing or corrupted table and moves to next record
(in REDO or UNDO phase) to be more robust; warns if happens in UNDO phase.
Bugfix for UNDO_KEY_DELETE_WITH_ROOT (tested in ma_test_recovery)
and maria_enable_indexes().
Create missing bitmaps when needed (there can be more than one to create,
in rare cases), log a record for this.
include/myisamchk.h:
new flag: bulk insert repair mustn't bump create_rename_lsn
mysql-test/lib/mtr_report.pl:
skip normal warning in maria-recovery.test
mysql-test/r/maria-recovery.result:
result: crash before bulk insert is committed, causes proper rollback,
and crash right after OPTIMIZE replaces index file with new index file
leads to table marked corrupted and recovery not failing.
mysql-test/t/maria-recovery.test:
- can't check the table or it would commit the transaction,
but check is made after recovery.
- test of crash before bulk-insert-with-repair is committed
(to see if it is rolled back), and of crash after OPTIMIZE has replaced
index file but not finished all operations (to see if recovery fails -
it used to assert when trying to execute an old REDO on the new
index).
storage/maria/CMakeLists.txt:
new file
storage/maria/Makefile.am:
new file
storage/maria/ha_maria.cc:
- If bulk insert on a transactional table using an index repair:
table is initially empty, so don't log REDO/UNDO for data rows
(optimization), just log an UNDO_BULK_INSERT_WITH_REPAIR
which will, if executed, empty the data and index file. Re-enable
logging in end_bulk_insert().
- write log record for repair operation only after it's fully done,
index sort including (maria_repair*() used to write the log record).
- Adding back file->trn=NULL which was removed by mistake earlier.
storage/maria/ha_maria.h:
new member (see ha_maria.cc)
storage/maria/ma_bitmap.c:
Functions to create missing bitmaps:
- one function which creates missing bitmaps in page cache, except
the missing one with max offset which it does not put into page cache
as it will be modified very soon.
- one function which the one above calls, and creates bitmaps in page
cache
- one function to execute REDO_BITMAP_NEW_PAGE which uses the second
one above.
storage/maria/ma_blockrec.c:
- when logging REDO_DELETE_ALL, not only 'records' and 'checksum'
has to be reset under log's mutex.
- execution of REDO_INSERT_ROW_BLOBS now checks the dirty pages' list
- execution of UNDO_BULK_INSERT_WITH_REPAIR
storage/maria/ma_blockrec.h:
new functions
storage/maria/ma_check.c:
- table-flush-before-repair is moved to a separate function reused
by maria_sort_index(); syncing is added
- maria_repair() is allowed to re-enable logging only if it is the one
which disabled it.
- "_ma_flush_table_files_after_repair" was a bad name, it's not after
repair now, and it should not sync as we do more changes to the files
shortly after (sync is postponed to when writing the log record)
- REDO_REPAIR record should be written only after all repair
operations (in particular after sorting index in ha_mara::repair())
- close to the end of repair by sort, flushing of pages must happen
also in the non-quick case, to prepare for the sync at end.
- in parallel repair, some page flushes are not needed as done
by initialize_variables_for_repair().
storage/maria/ma_create.c:
Update skip_redo_lsn, create_rename_lsn optionally.
storage/maria/ma_delete_all.c:
Need to sync files at end of maria_delete_all_rows(), if transactional.
storage/maria/ma_extra.c:
During repair, we sometimes call _ma_flush_table_files() (via
_ma_flush_table_files_before_swap()) while there is a WRITE_CACHE.
storage/maria/ma_key_recover.c:
- when we see CLR_END for UNDO_BULK_INSERT_WITH_REPAIR, re-enable
indices.
- fixing bug: _ma_apply_undo_key_delete() parsed UNDO_KEY_DELETE_WITH_ROOT
wrongly, leading to recovery failure
storage/maria/ma_key_recover.h:
new prototype
storage/maria/ma_locking.c:
DBUG_VOID_RETURN missing
storage/maria/ma_loghandler.c:
UNDO for bulk insert with repair, and REDO for creating bitmaps.
LOGREC_FIRST_FREE to not have to change the for() every time we
add a new record type.
storage/maria/ma_loghandler.h:
new UNDO and REDO
storage/maria/ma_open.c:
Move share.kfile.file=kfile up a bit, so that _ma_update_state_lsns()
can get its value, this fixes a bug where LSN_REPAIRED_BY_MARIA_CHK
was not corrected on disk by maria_open().
Store skip_redo_lsn in index' header.
maria_enable_indexes() had a bug for BLOCK_RECORD, where an empty
file has one page, not 0 bytes.
storage/maria/ma_recovery.c:
- Skip a corrupted, missing, or repaired-with-maria_chk, table in
recovery: don't fail, just go to next REDO or UNDO; but if an UNDO
is skipped in UNDO phase we issue warnings.
- Skip REDO|UNDO in REDO phase if <skip_redo_lsn.
- If UNDO phase fails, delete transactions to not make trnman
assert.
- Update skip_redo_lsn when playing REDO_CREATE_TABLE
- Don't record UNDOs for old transactions which we don't know (long_trid==0)
- Bugfix for UNDO_KEY_DELETE_WITH_ROOT (see ma_key_recover.c)
- Execution of UNDO_BULK_INSERT_WITH_REPAIR
- Don't try to find a page number in REDO_DELETE_ALL
- Pieces moved to ma_recovery_util.c
storage/maria/ma_rename.c:
name change
storage/maria/ma_static.c:
I modified layout of the index' header (inserted skip_redo_lsn in its middle)
storage/maria/ma_test2.c:
allow breaking the test towards the end, tests execution of
UNDO_KEY_DELETE_WITH_ROOT
storage/maria/ma_test_recovery.expected:
6 as testflag instead of 4
storage/maria/ma_test_recovery:
Increase the amount of rollback work to do when testing recovery
with ma_test2; this reproduces the UNDO_KEY_DELETE_WITH_ROOT bug.
storage/maria/maria_chk.c:
skip_redo_lsn should be updated too, for consistency.
Write a REDO_REPAIR after all operations (including sort-records)
have been done.
No reason to flush blocks after maria_chk_data_link() and
maria_sort_records(), there is maria_close() in the end.
write_log_record() is a function, to not clutter maria_chk().
storage/maria/maria_def.h:
New member skip_redo_lsn in the state, and comments
storage/maria/maria_pack.c:
skip_redo_lsn should be updated too, for consistency
storage/maria/ma_recovery_util.c:
_ma_redo_not_needed_for_page(), defined in ma_recovery.c, is needed
by ma_blockrec.c; this causes link issues, resolved by putting
_ma_redo_not_needed_for_page() into a new file (so that it is not
in the same file as repair-related objects of ma_recovery.c).
storage/maria/ma_recovery_util.h:

WL#3071 Maria checkpoint
Finally this is the real checkpoint code.
It however exhibits unstabilities when a checkpoint runs concurrently
with data-modifying clients (table corruption, transaction log's
assertions) so for now a checkpoint is taken only at startup after
recovery and at shutdown, i.e. not in concurrent situations. Later
we will let it run periodically, as well as flush dirty pages
periodically (almost all needed code is there already, only pagecache
code is written but not committed).
WL#3072 Maria recovery
* replacing UNDO_ROW_PURGE with CLR_END; testing of those CLR_END via
ma_test2 which has INSERTs failing with duplicate keys.
* replaying of REDO_RENAME_TABLE
Now, off to test Recovery in ha_maria :)
BitKeeper/deleted/.del-ma_least_recently_dirtied.c:
Delete: storage/maria/ma_least_recently_dirtied.c
BitKeeper/deleted/.del-ma_least_recently_dirtied.h:
Delete: storage/maria/ma_least_recently_dirtied.h
storage/maria/Makefile.am:
compile Checkpoint module
storage/maria/ha_maria.cc:
When ha_maria starts, do a recovery from last checkpoint.
Take a checkpoint when that recovery has ended and when ha_maria
shuts down cleanly.
storage/maria/ma_blockrec.c:
* even if my_sync() fails we have to my_close() (otherwise we leak
a descriptor)
* UNDO_ROW_PURGE is replaced by a simple CLR_END for UNDO_ROW_INSERT,
as promised in the old comment; it gives us skipping during the
UNDO phase.
storage/maria/ma_check.c:
All REDOs before create_rename_lsn are ignored by Recovery. So
create_rename_lsn must be set only after all data/index has been
flushed and forced to disk. We thus move write_log_record_for_repair()
to after _ma_flush_tables_files_after_repair().
storage/maria/ma_checkpoint.c:
Checkpoint module.
storage/maria/ma_checkpoint.h:
optional argument if caller wants a thread to periodically take
checkpoints and flush dirty pages.
storage/maria/ma_create.c:
* no need to init some vars as the initial bzero(share) takes care of this.
* update to new function's name
* even if we fail in my_sync() we have to my_close()
storage/maria/ma_extra.c:
Checkpoint reads share->last_version under intern_lock, so we make
maria_extra() update it under intern_lock. THR_LOCK_maria still needed
because of _ma_test_if_reopen().
storage/maria/ma_init.c:
destroy checkpoint module when Maria shuts down.
storage/maria/ma_loghandler.c:
* UNDO_ROW_PURGE gone (see ma_blockrec.c)
* we need to remember the LSN of the LOGREC_FILE_ID for a share,
because this LSN is needed into the checkpoint record (Recovery wants
to know the validity domain of an id->name mapping)
* translog_get_horizon_no_lock() needed for Checkpoint
* comment about failing assertion (Sanja knows)
* translog_init_reader_data() thought that translog_read_record_header_scan()
returns 0 in case of error, but 0 just means "0-length header".
* translog_assign_id_to_share() now needs the MARIA_HA because
LOGREC_FILE_ID uses a log-write hook.
* Verify that (de)assignment of share->id happens only under intern_lock,
as Checkpoint reads this id with intern_lock.
* translog_purge() can accept TRANSLOG_ADDRESS, not necessarily
a real LSN.
storage/maria/ma_loghandler.h:
prototype updates
storage/maria/ma_open.c:
no need to initialize "res"
storage/maria/ma_pagecache.c:
When taking a checkpoint, we don't need to know the maximum rec_lsn
of dirty pages; this LSN was intended to be used in the two-checkpoint
rule, but last_checkpoint_lsn is as good.
4 bytes for stored_list_size is enough as PAGECACHE::blocks (number
of blocks which the pagecache can contain) is int.
storage/maria/ma_pagecache.h:
new prototype
storage/maria/ma_recovery.c:
* added replaying of REDO_RENAME_TABLE
* UNDO_ROW_PURGE gone (see ma_blockrec.c), replaced by CLR_END
* Recovery from the last checkpoint record now possible
* In new_table() we skip the table if the id->name mapping is older than
create_rename_lsn (mapping dates from lsn_of_file_id).
* in get_MARIA_HA_from_REDO_record() we skip the record
if the id->name mapping is newer than the record (can happen if processing
a record which is before the checkpoint record).
* parse_checkpoint_record() has to return a LSN, that's what caller expects
storage/maria/ma_rename.c:
new function's name; log end zeroes of tables' names (ease recovery)
storage/maria/ma_test2.c:
* equivalent of ma_test1's --test-undo added (named -u here).
* -t=1 now stops right after creating the table, so that
we can test undoing of INSERTs with duplicate keys (which tests the
CLR_END logged by _ma_write_abort_block_record()).
storage/maria/ma_test_recovery.expected:
Result of testing undoing of INSERTs with duplicate keys; there are
some differences in maria_chk -dvv but they are normal (removing
records does not shrink data/index file, does not put back the
"analyzed, optimized keys"(etc) index state.
storage/maria/ma_test_recovery:
Test undoing of INSERTs with duplicate keys, using ma_test2;
when such INSERT happens, it logs REDO_INSERT, UNDO_INSERT, REDO_DELETE,
CLR_END; we abort after that, and test that CLR_END causes recovery
to jump over UNDO_INSERT.
storage/maria/ma_write.c:
comment
storage/maria/maria_chk.c:
comment
storage/maria/maria_def.h:
* a new bit in MARIA_SHARE::in_checkpoint, used to build a list
of unique shares during Checkpoint.
* MARIA_SHARE::lsn_of_file_id added: the LSN of the last LOGREC_FILE_ID
for this share; needed to know to which LSN domain the mappings
found in the Checkpoint record apply (new mappings should not apply
to old REDOs).
storage/maria/trnman.c:
* small changes to how trnman_collect_transactions() fills its buffer;
it also uses a non-dummy lsn_read_non_atomic() found in ma_checkpoint.h

WL#3071 Maria checkpoint
Finally this is the real checkpoint code.
It however exhibits unstabilities when a checkpoint runs concurrently
with data-modifying clients (table corruption, transaction log's
assertions) so for now a checkpoint is taken only at startup after
recovery and at shutdown, i.e. not in concurrent situations. Later
we will let it run periodically, as well as flush dirty pages
periodically (almost all needed code is there already, only pagecache
code is written but not committed).
WL#3072 Maria recovery
* replacing UNDO_ROW_PURGE with CLR_END; testing of those CLR_END via
ma_test2 which has INSERTs failing with duplicate keys.
* replaying of REDO_RENAME_TABLE
Now, off to test Recovery in ha_maria :)

* UNDO_ROW_PURGE is replaced by a simple CLR_END for UNDO_ROW_INSERT,
as promised in the old comment; it gives us skipping during the
UNDO phase.
storage/maria/ma_check.c:
All REDOs before create_rename_lsn are ignored by Recovery. So
create_rename_lsn must be set only after all data/index has been
flushed and forced to disk. We thus move write_log_record_for_repair()
to after _ma_flush_tables_files_after_repair().

storage/maria/ma_loghandler.c:

* comment about failing assertion (Sanja knows)
* translog_init_reader_data() thought that translog_read_record_header_scan()

WL#3071 Maria checkpoint
Finally this is the real checkpoint code.
It however exhibits unstabilities when a checkpoint runs concurrently
with data-modifying clients (table corruption, transaction log's
assertions) so for now a checkpoint is taken only at startup after
recovery and at shutdown, i.e. not in concurrent situations. Later
we will let it run periodically, as well as flush dirty pages
periodically (almost all needed code is there already, only pagecache
code is written but not committed).
WL#3072 Maria recovery
* replacing UNDO_ROW_PURGE with CLR_END; testing of those CLR_END via
ma_test2 which has INSERTs failing with duplicate keys.
* replaying of REDO_RENAME_TABLE
Now, off to test Recovery in ha_maria :)
BitKeeper/deleted/.del-ma_least_recently_dirtied.c:
Delete: storage/maria/ma_least_recently_dirtied.c
BitKeeper/deleted/.del-ma_least_recently_dirtied.h:
Delete: storage/maria/ma_least_recently_dirtied.h
storage/maria/Makefile.am:
compile Checkpoint module
storage/maria/ha_maria.cc:
When ha_maria starts, do a recovery from last checkpoint.
Take a checkpoint when that recovery has ended and when ha_maria
shuts down cleanly.
storage/maria/ma_blockrec.c:
* even if my_sync() fails we have to my_close() (otherwise we leak
a descriptor)
* UNDO_ROW_PURGE is replaced by a simple CLR_END for UNDO_ROW_INSERT,
as promised in the old comment; it gives us skipping during the
UNDO phase.
storage/maria/ma_check.c:
All REDOs before create_rename_lsn are ignored by Recovery. So
create_rename_lsn must be set only after all data/index has been
flushed and forced to disk. We thus move write_log_record_for_repair()
to after _ma_flush_tables_files_after_repair().
storage/maria/ma_checkpoint.c:
Checkpoint module.
storage/maria/ma_checkpoint.h:
optional argument if caller wants a thread to periodically take
checkpoints and flush dirty pages.
storage/maria/ma_create.c:
* no need to init some vars as the initial bzero(share) takes care of this.
* update to new function's name
* even if we fail in my_sync() we have to my_close()
storage/maria/ma_extra.c:
Checkpoint reads share->last_version under intern_lock, so we make
maria_extra() update it under intern_lock. THR_LOCK_maria still needed
because of _ma_test_if_reopen().
storage/maria/ma_init.c:
destroy checkpoint module when Maria shuts down.
storage/maria/ma_loghandler.c:
* UNDO_ROW_PURGE gone (see ma_blockrec.c)
* we need to remember the LSN of the LOGREC_FILE_ID for a share,
because this LSN is needed into the checkpoint record (Recovery wants
to know the validity domain of an id->name mapping)
* translog_get_horizon_no_lock() needed for Checkpoint
* comment about failing assertion (Sanja knows)
* translog_init_reader_data() thought that translog_read_record_header_scan()
returns 0 in case of error, but 0 just means "0-length header".
* translog_assign_id_to_share() now needs the MARIA_HA because
LOGREC_FILE_ID uses a log-write hook.
* Verify that (de)assignment of share->id happens only under intern_lock,
as Checkpoint reads this id with intern_lock.
* translog_purge() can accept TRANSLOG_ADDRESS, not necessarily
a real LSN.
storage/maria/ma_loghandler.h:
prototype updates
storage/maria/ma_open.c:
no need to initialize "res"
storage/maria/ma_pagecache.c:
When taking a checkpoint, we don't need to know the maximum rec_lsn
of dirty pages; this LSN was intended to be used in the two-checkpoint
rule, but last_checkpoint_lsn is as good.
4 bytes for stored_list_size is enough as PAGECACHE::blocks (number
of blocks which the pagecache can contain) is int.
storage/maria/ma_pagecache.h:
new prototype
storage/maria/ma_recovery.c:
* added replaying of REDO_RENAME_TABLE
* UNDO_ROW_PURGE gone (see ma_blockrec.c), replaced by CLR_END
* Recovery from the last checkpoint record now possible
* In new_table() we skip the table if the id->name mapping is older than
create_rename_lsn (mapping dates from lsn_of_file_id).
* in get_MARIA_HA_from_REDO_record() we skip the record
if the id->name mapping is newer than the record (can happen if processing
a record which is before the checkpoint record).
* parse_checkpoint_record() has to return a LSN, that's what caller expects
storage/maria/ma_rename.c:
new function's name; log end zeroes of tables' names (ease recovery)
storage/maria/ma_test2.c:
* equivalent of ma_test1's --test-undo added (named -u here).
* -t=1 now stops right after creating the table, so that
we can test undoing of INSERTs with duplicate keys (which tests the
CLR_END logged by _ma_write_abort_block_record()).
storage/maria/ma_test_recovery.expected:
Result of testing undoing of INSERTs with duplicate keys; there are
some differences in maria_chk -dvv but they are normal (removing
records does not shrink data/index file, does not put back the
"analyzed, optimized keys"(etc) index state.
storage/maria/ma_test_recovery:
Test undoing of INSERTs with duplicate keys, using ma_test2;
when such INSERT happens, it logs REDO_INSERT, UNDO_INSERT, REDO_DELETE,
CLR_END; we abort after that, and test that CLR_END causes recovery
to jump over UNDO_INSERT.
storage/maria/ma_write.c:
comment
storage/maria/maria_chk.c:
comment
storage/maria/maria_def.h:
* a new bit in MARIA_SHARE::in_checkpoint, used to build a list
of unique shares during Checkpoint.
* MARIA_SHARE::lsn_of_file_id added: the LSN of the last LOGREC_FILE_ID
for this share; needed to know to which LSN domain the mappings
found in the Checkpoint record apply (new mappings should not apply
to old REDOs).
storage/maria/trnman.c:
* small changes to how trnman_collect_transactions() fills its buffer;
it also uses a non-dummy lsn_read_non_atomic() found in ma_checkpoint.h

Ensure we store pages in pinned pages even if read failed. (If not we will have pages pinned forever in page cache)
Write original extent information in UNDO entry, not compacted ones (we need position to tails!)
When setting BLOCKUSED_USED, don't clear other bits (we have to preserve BLOCKUSED_USE_ORG_BITMAP)
Fixed som bugs in directory handling
Fixed bug where we wrote wrong lsn to blob pages
Added separate blob_buffer for fixing bug when updating row that had char/varchar that spanned several pages and also had blobs
Ensure we call _ma_bitmap_flushable() also in case of errors
When doing an update, first delete old entries, then search in bitmap for where to put new information
Info->s -> share
Rowid -> rowid
More DBUG_ASSERT()

More tests
storage/maria/ma_test_recovery.expected:
Updated results
storage/maria/ma_test_recovery:
Changed tests to use bigger blobs (not just 1K)
Added new tests that tests recovery of update with blobs

WL#3072 Maria Recovery
misc fixes of execution of UNDOs in the UNDO phase:
- into the CLR_END, store the LSN of the _previous_ UNDO (we debated
what was best, so far we're going with "previous"; later we can change
to "current" if needed), and store the type of record which is being
undone (needed to know how to update state.records when we see the
CLR_END during the REDO phase).
- declaring all UNDOs and CLR_END as "compressed"
- when executing an UNDO in the UNDO phase, state.records is updated
as a hook when writing CLR_END (needed for "recovery of the state"),
and so is trn->undo_lsn (needed for when we have checkpoints).
- bugfix (execution of UNDO_ROW_DELETE didn't store the correct checksum
into the re-inserted row, maria_chk -r thus threw the row away).
- modifications of ma_test1: where to stop is now driven by --testflag;
--test-undo just tells how to stop (flush data, flush log, nothing).
- ma_test_recovery: testing of the UNDO phase, more testing of the
REDO phase, identification of a bug.
storage/maria/ma_blockrec.c:
- bugfix: execution of UNDO_ROW_DELETE didn't store the correct
checksum into the row (leading to "maria_chk -r" eliminating the
re-inserted row, net effect was that rollback appeared to have
rolled back no deletion). Reason was that write_block_record() used
info->cur_row.checksum, while "row" can be != &info->cur_row
(case of UNDO_ROW_DELETE). After fixing this, problems with
_ma_update_block_record() appeared; indeed checksum was computed
by allocate_and_write_block_record() while _ma_update_block_record()
directly calls write_block_record(). Solution is to compute checksum
in write_block_record() instead.
- when executing an UNDO, we now pass the LSN of the _previous_ UNDO
to block_format functions. This LSN can be 0 (if the being-executed UNDO
was the transaction's first UNDO), so "undo_lsn==0" cannot work
anymore to indicate "this is not UNDO work". Using undo_lsn==LSN_ERROR
instead (this is an impossible LSN).
- store into CLR_END the type of log record which was undone
(INSERT/UPDATE/DELETE); needed for Recovery to know if/how it has
to update state.records if it sees this CLR_END in the REDO phase.
- when writing the CLR_END in _ma_apply_undo_row_insert(),
the place to store file's id is log_data+LSN_STORE_SIZE.
- in _ma_apply_undo_row_insert(), the records-- is moved
to a hook when writing the CLR_END (this way it is under log's mutex
which is needed for "recovery of the state")
storage/maria/ma_loghandler.c:
- all UNDOs, and CLR_END, start with the LSN of another UNDO; so
we can declare them "compressed".
- write_hook_for_clr_end() to set trn->undo_lsn (to the previous
UNDO's LSN) under log's lock (like UNDOs set trn->undo_lsn under log's
lock), and also update, if appropriate, state.records.
- reset share->id to 0 when deassigning; not useful for now but
sounds logical.
storage/maria/ma_recovery.c:
- if no table is found for a REDO, it's not an error; for an UNDO, it is
- in the REDO phase, when we see a CLR_END we must update trn->undo_lsn
and sometimes state.records.
- in the UNDO phase, when we execute an UNDO_ROW_INSERT:
* update trn->undo_lsn only after executing the record
* store the _previous_ undo_lsn into the CLR_END
- at the end of the REDO phase, when we recreate TRN objects, they
have already their long id in the log (either via a
LOGREC_LONG_TRANSACTION_ID, or in a checkpoint record), don't write
a new, useless LOGREC_LONG_TRANSACTION_ID for them.
storage/maria/ma_test1.c:
* where to stop execution is now driven by --testflag and not --test-undo
(ma_test2 already has --testflag for the same purpose). This allows
us to do a clean stop (with commit) at any point.
* --test-undo=# tells how to abort (flush all pages (which implies
flushing log) or only log or nothing); all such "ways of crashing"
are tested in ma_test_recovery
storage/maria/ma_test_recovery:
* Testing execution of UNDOs, with and without BLOBs.
* Testing idempotency of REDOs.
* See @todo for a probable bug with BLOBs.
* maria_chk -rq instead of -r, as with -q it nicely stops on any
problem in the data file (like the checksum bug see comment of
ma_blockrec.c).
* Testing if log was written by UNDO phase (often expected),
not written by REDO phase (always expected).
* Less output on the screen, compares with expected output in the end.
* some shell thingies like "set --" and $# are courtesy of
Danny and Pekka.
storage/maria/maria_read_log.c:
when only displaying the records, don't do an UNDO phase
storage/maria/ma_test_recovery.expected:
This is the expected output of a great part of ma_test_recovery.
ma_test_recovery compares its output to the expected output
and tells if different.
If we look at this file it mentions differences in checksum
(normal, it's not recovered yet) and in records count
(getting a correct records' count when recovery starts on an
already existing table, like when testing rollback,
is coded but not yet pushed).

WL#3072 Maria Recovery
misc fixes of execution of UNDOs in the UNDO phase:
- into the CLR_END, store the LSN of the _previous_ UNDO (we debated
what was best, so far we're going with "previous"; later we can change
to "current" if needed), and store the type of record which is being
undone (needed to know how to update state.records when we see the
CLR_END during the REDO phase).
- declaring all UNDOs and CLR_END as "compressed"
- when executing an UNDO in the UNDO phase, state.records is updated
as a hook when writing CLR_END (needed for "recovery of the state"),
and so is trn->undo_lsn (needed for when we have checkpoints).
- bugfix (execution of UNDO_ROW_DELETE didn't store the correct checksum
into the re-inserted row, maria_chk -r thus threw the row away).
- modifications of ma_test1: where to stop is now driven by --testflag;
--test-undo just tells how to stop (flush data, flush log, nothing).
- ma_test_recovery: testing of the UNDO phase, more testing of the
REDO phase, identification of a bug.
storage/maria/ma_blockrec.c:
- bugfix: execution of UNDO_ROW_DELETE didn't store the correct
checksum into the row (leading to "maria_chk -r" eliminating the
re-inserted row, net effect was that rollback appeared to have
rolled back no deletion). Reason was that write_block_record() used
info->cur_row.checksum, while "row" can be != &info->cur_row
(case of UNDO_ROW_DELETE). After fixing this, problems with
_ma_update_block_record() appeared; indeed checksum was computed
by allocate_and_write_block_record() while _ma_update_block_record()
directly calls write_block_record(). Solution is to compute checksum
in write_block_record() instead.
- when executing an UNDO, we now pass the LSN of the _previous_ UNDO
to block_format functions. This LSN can be 0 (if the being-executed UNDO
was the transaction's first UNDO), so "undo_lsn==0" cannot work
anymore to indicate "this is not UNDO work". Using undo_lsn==LSN_ERROR
instead (this is an impossible LSN).
- store into CLR_END the type of log record which was undone
(INSERT/UPDATE/DELETE); needed for Recovery to know if/how it has
to update state.records if it sees this CLR_END in the REDO phase.
- when writing the CLR_END in _ma_apply_undo_row_insert(),
the place to store file's id is log_data+LSN_STORE_SIZE.
- in _ma_apply_undo_row_insert(), the records-- is moved
to a hook when writing the CLR_END (this way it is under log's mutex
which is needed for "recovery of the state")
storage/maria/ma_loghandler.c:
- all UNDOs, and CLR_END, start with the LSN of another UNDO; so
we can declare them "compressed".
- write_hook_for_clr_end() to set trn->undo_lsn (to the previous
UNDO's LSN) under log's lock (like UNDOs set trn->undo_lsn under log's
lock), and also update, if appropriate, state.records.
- reset share->id to 0 when deassigning; not useful for now but
sounds logical.
storage/maria/ma_recovery.c:
- if no table is found for a REDO, it's not an error; for an UNDO, it is
- in the REDO phase, when we see a CLR_END we must update trn->undo_lsn
and sometimes state.records.
- in the UNDO phase, when we execute an UNDO_ROW_INSERT:
* update trn->undo_lsn only after executing the record
* store the _previous_ undo_lsn into the CLR_END
- at the end of the REDO phase, when we recreate TRN objects, they
have already their long id in the log (either via a
LOGREC_LONG_TRANSACTION_ID, or in a checkpoint record), don't write
a new, useless LOGREC_LONG_TRANSACTION_ID for them.
storage/maria/ma_test1.c:
* where to stop execution is now driven by --testflag and not --test-undo
(ma_test2 already has --testflag for the same purpose). This allows
us to do a clean stop (with commit) at any point.
* --test-undo=# tells how to abort (flush all pages (which implies
flushing log) or only log or nothing); all such "ways of crashing"
are tested in ma_test_recovery
storage/maria/ma_test_recovery:
* Testing execution of UNDOs, with and without BLOBs.
* Testing idempotency of REDOs.
* See @todo for a probable bug with BLOBs.
* maria_chk -rq instead of -r, as with -q it nicely stops on any
problem in the data file (like the checksum bug see comment of
ma_blockrec.c).
* Testing if log was written by UNDO phase (often expected),
not written by REDO phase (always expected).
* Less output on the screen, compares with expected output in the end.
* some shell thingies like "set --" and $# are courtesy of
Danny and Pekka.
storage/maria/maria_read_log.c:
when only displaying the records, don't do an UNDO phase
storage/maria/ma_test_recovery.expected:
This is the expected output of a great part of ma_test_recovery.
ma_test_recovery compares its output to the expected output
and tells if different.
If we look at this file it mentions differences in checksum
(normal, it's not recovered yet) and in records count
(getting a correct records' count when recovery starts on an
already existing table, like when testing rollback,
is coded but not yet pushed).

Changed _ma_apply_undo_row_delete() and _ma_apply_undo_row_update() to put row in it's original position
Ensure allocation of tail blocks are of at least MIN_TAIL_SIZE.
Ensure we store pages in pinned pages even if read failed. (If not we will have pages pinned forever in page cache)
Write original extent information in UNDO entry, not compacted ones (we need position to tails!)
When setting BLOCKUSED_USED, don't clear other bits (we have to preserve BLOCKUSED_USE_ORG_BITMAP)
Fixed som bugs in directory handling
Fixed bug where we wrote wrong lsn to blob pages
Added separate blob_buffer for fixing bug when updating row that had char/varchar that spanned several pages and also had blobs
Ensure we call _ma_bitmap_flushable() also in case of errors
When doing an update, first delete old entries, then search in bitmap for where to put new information
Info->s -> share
Rowid -> rowid
More DBUG_ASSERT()

First created blob is now of max blob length to ensure we have at least one big blob in the table
storage/maria/ma_test_all.sh:
More tests
storage/maria/ma_test_recovery.expected:
Updated results
storage/maria/ma_test_recovery:
Changed tests to use bigger blobs (not just 1K)
Added new tests that tests recovery of update with blobs
Removed comparision of .MAD file as it's not guranteed that recovery from scratch gives identical data file as original update

Fixed some bugs with 'non_flushable' marking of bitmap pages
Don't use 'non_flushable' marking of bitmap pages for not transactional tables
SHOW CREATE TABLE now shows if table was created with page checksums
Fixed a lot of bugs with BLOB handling in case of update/REDO and UNDO
More tests (especially for blobs) and DBUG_ASSERTS()
More readable output from maria_read_log and maria_chk
Fixed wrong shift that caused Maria to crash on files > 4G
Mark tables as crashed of REDO fails
dbug/dbug.c:
Changed to use my_bool (allowed me to remove some windows specific code)

storage/maria/Makefile.am:
Added ma_test_big.sh
storage/maria/ha_maria.cc:
Store in create_info if page checksums are used (For SHOW CREATE TABLE)
storage/maria/ma_bitmap.c:
Added _ma_bitmap_wait_or_flush() to cause reader of bitmap pages to wait with reading until bitmap is flushed.
Use TAIL_PAGE_COUNT_MARKER for tail pages
Set 'sub_blocks' for and only for the head page or for the first extent of a blob. This is needed for store_extent_info() to be able to set START_EXTENT_BIT's
Don't allocate more than 0x3ffff pages in one extent (We need bit 0x4000 as a START_EXTENT_BIT)
Increase the calculated 'head_length' with the number of bytes used for extents.
Update row->space_on_head_page also in _ma_bitmap_find_new_place()
Make _ma_bitmap_get_page_bits() global. (Needed for UNDO handling)
Changed _ma_bitmap_flushable() to take MARIA_HA instead of MARIA_SHARE.
This was needed to be able to mark the handler if we had a 'non_flushable' call pending or not.
Don't use 'non_flushable' marking of bitmap pages for not transactional tables.
Added BLOCKUSED_USE_ORG_BITMAP handling also for tail pages.
Added more DBUG_ASSERT() to find possible errors in other code
Some code simplications by adding new local variables
storage/maria/ma_blockrec.c:
UNDO of rows now puts back all part of the row on their original pages and positions.
Changed UNDO of DELETE and UNDO of UPDATE to contain information about the original length of data on head block and also extent information
This changes a lot of logic as now an insert of a row on a page may happen to any position (and not just to the first or next free)
Use PAGE_COUNT to mark if an extent is the start of of a blob. (Needed for extent_to_bitmap_blocks())
Added check_directory() for checking that directroy entries are correct.
Added checking of row checksums when reading rows (with EXTRA_DEBUG)
Added make_space_for_directory() and extend_directory() for doing expansion of directory

Changed make_empty_page() to allow optional creation of directory entry
Changed delete_head_or_tail() and _ma_apply_undo_row_isnert() to not copy pagecache block (speed optimization)
Changed _ma_apply_redo_insert_row_head_or_tail() to be able to insert new row at any position on 'new' page
Changed _ma_apply_undo_row_delete() and _ma_apply_undo_row_update() to put row in it's original position
Ensure allocation of tail blocks are of at least MIN_TAIL_SIZE.
Ensure we store pages in pinned pages even if read failed. (If not we will have pages pinned forever in page cache)
Write original extent information in UNDO entry, not compacted ones (we need position to tails!)
When setting BLOCKUSED_USED, don't clear other bits (we have to preserve BLOCKUSED_USE_ORG_BITMAP)
Fixed som bugs in directory handling
Fixed bug where we wrote wrong lsn to blob pages
Added separate blob_buffer for fixing bug when updating row that had char/varchar that spanned several pages and also had blobs
Ensure we call _ma_bitmap_flushable() also in case of errors
When doing an update, first delete old entries, then search in bitmap for where to put new information
Info->s -> share
Rowid -> rowid
More DBUG_ASSERT()
storage/maria/ma_blockrec.h:
Added START_EXTENT_BIT and TAIL_PAGE_COUNT_MARKER
Added _ma_bitmap_wait_or_flush() and _ma_bitmap_get_page_bits()

Use PAGE_COUNT to mark if an extent is the start of of a blob. (Needed for extent_to_bitmap_blocks())
Added check_directory() for checking that directroy entries are correct.
Added checking of row checksums when reading rows (with EXTRA_DEBUG)
Added make_space_for_directory() and extend_directory() for doing expansion of directory

storage/maria/ha_maria.cc:
Store in create_info if page checksums are used (For SHOW CREATE TABLE)
storage/maria/ma_bitmap.c:
Added _ma_bitmap_wait_or_flush() to cause reader of bitmap pages to wait with reading until bitmap is flushed.
Use TAIL_PAGE_COUNT_MARKER for tail pages
Set 'sub_blocks' for and only for the head page or for the first extent of a blob. This is needed for store_extent_info() to be able to set START_EXTENT_BIT's
Don't allocate more than 0x3ffff pages in one extent (We need bit 0x4000 as a START_EXTENT_BIT)
Increase the calculated 'head_length' with the number of bytes used for extents.
Update row->space_on_head_page also in _ma_bitmap_find_new_place()
Make _ma_bitmap_get_page_bits() global. (Needed for UNDO handling)
Changed _ma_bitmap_flushable() to take MARIA_HA instead of MARIA_SHARE.
This was needed to be able to mark the handler if we had a 'non_flushable' call pending or not.
Don't use 'non_flushable' marking of bitmap pages for not transactional tables.
Added BLOCKUSED_USE_ORG_BITMAP handling also for tail pages.
Added more DBUG_ASSERT() to find possible errors in other code
Some code simplications by adding new local variables
storage/maria/ma_blockrec.c:
UNDO of rows now puts back all part of the row on their original pages and positions.
Changed UNDO of DELETE and UNDO of UPDATE to contain information about the original length of data on head block and also extent information
This changes a lot of logic as now an insert of a row on a page may happen to any position (and not just to the first or next free)
Use PAGE_COUNT to mark if an extent is the start of of a blob. (Needed for extent_to_bitmap_blocks())
Added check_directory() for checking that directroy entries are correct.
Added checking of row checksums when reading rows (with EXTRA_DEBUG)
Added make_space_for_directory() and extend_directory() for doing expansion of directory
Added get_rowpos_in_head_or_tail_page() to be able to store head/tail on original position in UNDO
Added extent_to_bitmap_blocks() to be able to generate original bitmap blocks from UNDO entry
Added _ma_update_at_original_place() for UNDO of DELETES
Added row->min_length to hold minmum required space needed on head page
Changed find_free_position() to use make_space_for_directory()
Changed make_empty_page() to allow optional creation of directory entry
Changed delete_head_or_tail() and _ma_apply_undo_row_isnert() to not copy pagecache block (speed optimization)
Changed _ma_apply_redo_insert_row_head_or_tail() to be able to insert new row at any position on 'new' page
Changed _ma_apply_undo_row_delete() and _ma_apply_undo_row_update() to put row in it's original position
Ensure allocation of tail blocks are of at least MIN_TAIL_SIZE.
Ensure we store pages in pinned pages even if read failed. (If not we will have pages pinned forever in page cache)
Write original extent information in UNDO entry, not compacted ones (we need position to tails!)
When setting BLOCKUSED_USED, don't clear other bits (we have to preserve BLOCKUSED_USE_ORG_BITMAP)
Fixed som bugs in directory handling
Fixed bug where we wrote wrong lsn to blob pages
Added separate blob_buffer for fixing bug when updating row that had char/varchar that spanned several pages and also had blobs
Ensure we call _ma_bitmap_flushable() also in case of errors
When doing an update, first delete old entries, then search in bitmap for where to put new information
Info->s -> share
Rowid -> rowid
More DBUG_ASSERT()
storage/maria/ma_blockrec.h:
Added START_EXTENT_BIT and TAIL_PAGE_COUNT_MARKER
Added _ma_bitmap_wait_or_flush() and _ma_bitmap_get_page_bits()
storage/maria/ma_check.c:
Don't write extra empty line if there is no deleted blocks
Ignore START_EXTENT_BIT's in page count
Call _ma_fast_unlock_key_del() to free key_del link
storage/maria/ma_close.c:
Ensure that used_key_del is 0. (If not, someone forgot to call _ma_unlock_key_del())
storage/maria/ma_create.c:
Changed constant to macro
storage/maria/ma_delete.c:
For deleted keys, log also position to row
storage/maria/ma_extra.c:
Release blob buffer at maria_reset() if bigger than MARIA_SMALL_BLOB_BUFFER
storage/maria/ma_key_recover.c:
Added bzero() of LSN that confused paged cache in case of uninitialized block
Mark file crashed if applying of index changes fails
Added calls to _ma_fast_unlock_key_del() for protection of shared key_del link.
storage/maria/ma_locking.c:
Added usage of MARIA_FILE_OPEN_COUNT_OFFSET
Added _ma_mark_file_crashed()
storage/maria/ma_loghandler.c:
Fixed bug where we logged uninitialized memory
storage/maria/ma_open.c:
Moved state->changed to be at start of state info on disk to allow one to easly mark files as crashed
storage/maria/ma_page.c:
Disable 'dummy' checksumming of pages as this gave false warnings.
(Need to investigate if this is ever needed)
storage/maria/ma_pagecache.c:
Fixed wrong shift that caused Maria to crash on files > 4G
storage/maria/ma_recovery.c:
In case of errors, start writing on new line if we where in %## %## printing mode (Made errors more readable)
Changed global variable name from warnings -> recovery_warnings
Use MARIA_FILE_CREATE_RENAME_LSN_OFFSET instead of constant
Removed special handling of row position for deleted keys. Keys now always includes row positions
_ma_apply_undo_row_delete() now gets page and row position
Added check that we don't loop forever when handling undo's (in case of bug in undo chain)
Print name of failed REDO/UNDO
storage/maria/ma_recovery.h:
Removed old comment
storage/maria/ma_static.c:
Chaned version number of Maria files to not accidently use old ones (becasue of change of ordering of status variables)
storage/maria/ma_test2.c:
Added option -u to specify number of rows to update
Changed old option -u to be -A, as for ma_test1
Fixed bug in update of rows with blobs (before blobs was always reset to empty on update)
First created blob is now of max blob length to ensure we have at least one big blob in the table
storage/maria/ma_test_all.sh:
More tests
storage/maria/ma_test_recovery.expected:
Updated results
storage/maria/ma_test_recovery:
Changed tests to use bigger blobs (not just 1K)
Added new tests that tests recovery of update with blobs
Removed comparision of .MAD file as it's not guranteed that recovery from scratch gives identical data file as original update
(compact_page() may be called at different times during normal execution and during REDO)
storage/maria/ma_update.c:
Simplify code (changed * to if)
storage/maria/maria_chk.c:
Make output more readable
storage/maria/maria_def.h:
Changed 'changed' to int to prepare for more bits
Added 2 more bytes to status information
Added 'st_mara_row->min_length' for storing min length needed on head page
Added 'st_mara_handler->blob_buff & blob_buff_size' for storing blobs
Moved all tunning parameters into one block
Added MARIA_SMALL_BLOB_BUFFER
Added _ma_mark_file_crashed()
storage/myisam/mi_test2.c:
Fixed bug in update of rows with blobs (before blobs was always reset to empty on update)
storage/maria/ma_test_big.sh:
Testing of insert, update, delete, recovery and undo of rows with blobs
Thanks to the random-ness of ma_test2 this is likely to find most bugs in the row handling

WL#3072 - Maria Recovery
Bulk insert: don't log REDO/UNDO for rows, log one UNDO which will
truncate files; this is an optimization and a bugfix (table was left
half-repaired by crash).
Repair: mark table crashed-on-repair at start, bump skip_redo_lsn at start,
this is easier for recovery (tells it to skip old REDOs or even UNDO
phase) and user (tells it to repair) in case of crash, sync files
in the end.
Recovery skips missing or corrupted table and moves to next record
(in REDO or UNDO phase) to be more robust; warns if happens in UNDO phase.
Bugfix for UNDO_KEY_DELETE_WITH_ROOT (tested in ma_test_recovery)
and maria_enable_indexes().
Create missing bitmaps when needed (there can be more than one to create,
in rare cases), log a record for this.
include/myisamchk.h:
new flag: bulk insert repair mustn't bump create_rename_lsn
mysql-test/lib/mtr_report.pl:
skip normal warning in maria-recovery.test
mysql-test/r/maria-recovery.result:
result: crash before bulk insert is committed, causes proper rollback,
and crash right after OPTIMIZE replaces index file with new index file
leads to table marked corrupted and recovery not failing.
mysql-test/t/maria-recovery.test:
- can't check the table or it would commit the transaction,
but check is made after recovery.
- test of crash before bulk-insert-with-repair is committed
(to see if it is rolled back), and of crash after OPTIMIZE has replaced
index file but not finished all operations (to see if recovery fails -
it used to assert when trying to execute an old REDO on the new
index).
storage/maria/CMakeLists.txt:
new file
storage/maria/Makefile.am:
new file
storage/maria/ha_maria.cc:
- If bulk insert on a transactional table using an index repair:
table is initially empty, so don't log REDO/UNDO for data rows
(optimization), just log an UNDO_BULK_INSERT_WITH_REPAIR
which will, if executed, empty the data and index file. Re-enable
logging in end_bulk_insert().
- write log record for repair operation only after it's fully done,
index sort including (maria_repair*() used to write the log record).
- Adding back file->trn=NULL which was removed by mistake earlier.
storage/maria/ha_maria.h:
new member (see ha_maria.cc)
storage/maria/ma_bitmap.c:
Functions to create missing bitmaps:
- one function which creates missing bitmaps in page cache, except
the missing one with max offset which it does not put into page cache
as it will be modified very soon.
- one function which the one above calls, and creates bitmaps in page
cache
- one function to execute REDO_BITMAP_NEW_PAGE which uses the second
one above.
storage/maria/ma_blockrec.c:
- when logging REDO_DELETE_ALL, not only 'records' and 'checksum'
has to be reset under log's mutex.
- execution of REDO_INSERT_ROW_BLOBS now checks the dirty pages' list
- execution of UNDO_BULK_INSERT_WITH_REPAIR
storage/maria/ma_blockrec.h:
new functions
storage/maria/ma_check.c:
- table-flush-before-repair is moved to a separate function reused
by maria_sort_index(); syncing is added
- maria_repair() is allowed to re-enable logging only if it is the one
which disabled it.
- "_ma_flush_table_files_after_repair" was a bad name, it's not after
repair now, and it should not sync as we do more changes to the files
shortly after (sync is postponed to when writing the log record)
- REDO_REPAIR record should be written only after all repair
operations (in particular after sorting index in ha_mara::repair())
- close to the end of repair by sort, flushing of pages must happen
also in the non-quick case, to prepare for the sync at end.
- in parallel repair, some page flushes are not needed as done
by initialize_variables_for_repair().
storage/maria/ma_create.c:
Update skip_redo_lsn, create_rename_lsn optionally.
storage/maria/ma_delete_all.c:
Need to sync files at end of maria_delete_all_rows(), if transactional.
storage/maria/ma_extra.c:
During repair, we sometimes call _ma_flush_table_files() (via
_ma_flush_table_files_before_swap()) while there is a WRITE_CACHE.
storage/maria/ma_key_recover.c:
- when we see CLR_END for UNDO_BULK_INSERT_WITH_REPAIR, re-enable
indices.
- fixing bug: _ma_apply_undo_key_delete() parsed UNDO_KEY_DELETE_WITH_ROOT
wrongly, leading to recovery failure
storage/maria/ma_key_recover.h:
new prototype
storage/maria/ma_locking.c:
DBUG_VOID_RETURN missing
storage/maria/ma_loghandler.c:
UNDO for bulk insert with repair, and REDO for creating bitmaps.
LOGREC_FIRST_FREE to not have to change the for() every time we
add a new record type.
storage/maria/ma_loghandler.h:
new UNDO and REDO
storage/maria/ma_open.c:
Move share.kfile.file=kfile up a bit, so that _ma_update_state_lsns()
can get its value, this fixes a bug where LSN_REPAIRED_BY_MARIA_CHK
was not corrected on disk by maria_open().
Store skip_redo_lsn in index' header.
maria_enable_indexes() had a bug for BLOCK_RECORD, where an empty
file has one page, not 0 bytes.
storage/maria/ma_recovery.c:
- Skip a corrupted, missing, or repaired-with-maria_chk, table in
recovery: don't fail, just go to next REDO or UNDO; but if an UNDO
is skipped in UNDO phase we issue warnings.
- Skip REDO|UNDO in REDO phase if <skip_redo_lsn.
- If UNDO phase fails, delete transactions to not make trnman
assert.
- Update skip_redo_lsn when playing REDO_CREATE_TABLE
- Don't record UNDOs for old transactions which we don't know (long_trid==0)
- Bugfix for UNDO_KEY_DELETE_WITH_ROOT (see ma_key_recover.c)
- Execution of UNDO_BULK_INSERT_WITH_REPAIR
- Don't try to find a page number in REDO_DELETE_ALL
- Pieces moved to ma_recovery_util.c
storage/maria/ma_rename.c:
name change
storage/maria/ma_static.c:
I modified layout of the index' header (inserted skip_redo_lsn in its middle)
storage/maria/ma_test2.c:
allow breaking the test towards the end, tests execution of
UNDO_KEY_DELETE_WITH_ROOT
storage/maria/ma_test_recovery.expected:
6 as testflag instead of 4
storage/maria/ma_test_recovery:
Increase the amount of rollback work to do when testing recovery
with ma_test2; this reproduces the UNDO_KEY_DELETE_WITH_ROOT bug.
storage/maria/maria_chk.c:
skip_redo_lsn should be updated too, for consistency.
Write a REDO_REPAIR after all operations (including sort-records)
have been done.
No reason to flush blocks after maria_chk_data_link() and
maria_sort_records(), there is maria_close() in the end.
write_log_record() is a function, to not clutter maria_chk().
storage/maria/maria_def.h:
New member skip_redo_lsn in the state, and comments
storage/maria/maria_pack.c:
skip_redo_lsn should be updated too, for consistency
storage/maria/ma_recovery_util.c:
_ma_redo_not_needed_for_page(), defined in ma_recovery.c, is needed
by ma_blockrec.c; this causes link issues, resolved by putting
_ma_redo_not_needed_for_page() into a new file (so that it is not
in the same file as repair-related objects of ma_recovery.c).
storage/maria/ma_recovery_util.h:

WL#3071 Maria checkpoint
Finally this is the real checkpoint code.
It however exhibits unstabilities when a checkpoint runs concurrently
with data-modifying clients (table corruption, transaction log's
assertions) so for now a checkpoint is taken only at startup after
recovery and at shutdown, i.e. not in concurrent situations. Later
we will let it run periodically, as well as flush dirty pages
periodically (almost all needed code is there already, only pagecache
code is written but not committed).
WL#3072 Maria recovery
* replacing UNDO_ROW_PURGE with CLR_END; testing of those CLR_END via
ma_test2 which has INSERTs failing with duplicate keys.
* replaying of REDO_RENAME_TABLE
Now, off to test Recovery in ha_maria :)
BitKeeper/deleted/.del-ma_least_recently_dirtied.c:
Delete: storage/maria/ma_least_recently_dirtied.c
BitKeeper/deleted/.del-ma_least_recently_dirtied.h:
Delete: storage/maria/ma_least_recently_dirtied.h
storage/maria/Makefile.am:
compile Checkpoint module
storage/maria/ha_maria.cc:
When ha_maria starts, do a recovery from last checkpoint.
Take a checkpoint when that recovery has ended and when ha_maria
shuts down cleanly.
storage/maria/ma_blockrec.c:
* even if my_sync() fails we have to my_close() (otherwise we leak
a descriptor)
* UNDO_ROW_PURGE is replaced by a simple CLR_END for UNDO_ROW_INSERT,
as promised in the old comment; it gives us skipping during the
UNDO phase.
storage/maria/ma_check.c:
All REDOs before create_rename_lsn are ignored by Recovery. So
create_rename_lsn must be set only after all data/index has been
flushed and forced to disk. We thus move write_log_record_for_repair()
to after _ma_flush_tables_files_after_repair().
storage/maria/ma_checkpoint.c:
Checkpoint module.
storage/maria/ma_checkpoint.h:
optional argument if caller wants a thread to periodically take
checkpoints and flush dirty pages.
storage/maria/ma_create.c:
* no need to init some vars as the initial bzero(share) takes care of this.
* update to new function's name
* even if we fail in my_sync() we have to my_close()
storage/maria/ma_extra.c:
Checkpoint reads share->last_version under intern_lock, so we make
maria_extra() update it under intern_lock. THR_LOCK_maria still needed
because of _ma_test_if_reopen().
storage/maria/ma_init.c:
destroy checkpoint module when Maria shuts down.
storage/maria/ma_loghandler.c:
* UNDO_ROW_PURGE gone (see ma_blockrec.c)
* we need to remember the LSN of the LOGREC_FILE_ID for a share,
because this LSN is needed into the checkpoint record (Recovery wants
to know the validity domain of an id->name mapping)
* translog_get_horizon_no_lock() needed for Checkpoint
* comment about failing assertion (Sanja knows)
* translog_init_reader_data() thought that translog_read_record_header_scan()
returns 0 in case of error, but 0 just means "0-length header".
* translog_assign_id_to_share() now needs the MARIA_HA because
LOGREC_FILE_ID uses a log-write hook.
* Verify that (de)assignment of share->id happens only under intern_lock,
as Checkpoint reads this id with intern_lock.
* translog_purge() can accept TRANSLOG_ADDRESS, not necessarily
a real LSN.
storage/maria/ma_loghandler.h:
prototype updates
storage/maria/ma_open.c:
no need to initialize "res"
storage/maria/ma_pagecache.c:
When taking a checkpoint, we don't need to know the maximum rec_lsn
of dirty pages; this LSN was intended to be used in the two-checkpoint
rule, but last_checkpoint_lsn is as good.
4 bytes for stored_list_size is enough as PAGECACHE::blocks (number
of blocks which the pagecache can contain) is int.
storage/maria/ma_pagecache.h:
new prototype
storage/maria/ma_recovery.c:
* added replaying of REDO_RENAME_TABLE
* UNDO_ROW_PURGE gone (see ma_blockrec.c), replaced by CLR_END
* Recovery from the last checkpoint record now possible
* In new_table() we skip the table if the id->name mapping is older than
create_rename_lsn (mapping dates from lsn_of_file_id).
* in get_MARIA_HA_from_REDO_record() we skip the record
if the id->name mapping is newer than the record (can happen if processing
a record which is before the checkpoint record).
* parse_checkpoint_record() has to return a LSN, that's what caller expects
storage/maria/ma_rename.c:
new function's name; log end zeroes of tables' names (ease recovery)
storage/maria/ma_test2.c:
* equivalent of ma_test1's --test-undo added (named -u here).
* -t=1 now stops right after creating the table, so that
we can test undoing of INSERTs with duplicate keys (which tests the
CLR_END logged by _ma_write_abort_block_record()).
storage/maria/ma_test_recovery.expected:
Result of testing undoing of INSERTs with duplicate keys; there are
some differences in maria_chk -dvv but they are normal (removing
records does not shrink data/index file, does not put back the
"analyzed, optimized keys"(etc) index state.
storage/maria/ma_test_recovery:
Test undoing of INSERTs with duplicate keys, using ma_test2;
when such INSERT happens, it logs REDO_INSERT, UNDO_INSERT, REDO_DELETE,
CLR_END; we abort after that, and test that CLR_END causes recovery
to jump over UNDO_INSERT.
storage/maria/ma_write.c:
comment
storage/maria/maria_chk.c:
comment
storage/maria/maria_def.h:
* a new bit in MARIA_SHARE::in_checkpoint, used to build a list
of unique shares during Checkpoint.
* MARIA_SHARE::lsn_of_file_id added: the LSN of the last LOGREC_FILE_ID
for this share; needed to know to which LSN domain the mappings
found in the Checkpoint record apply (new mappings should not apply
to old REDOs).
storage/maria/trnman.c:
* small changes to how trnman_collect_transactions() fills its buffer;
it also uses a non-dummy lsn_read_non_atomic() found in ma_checkpoint.h

WL#3071 Maria checkpoint
Finally this is the real checkpoint code.
It however exhibits unstabilities when a checkpoint runs concurrently
with data-modifying clients (table corruption, transaction log's
assertions) so for now a checkpoint is taken only at startup after
recovery and at shutdown, i.e. not in concurrent situations. Later
we will let it run periodically, as well as flush dirty pages
periodically (almost all needed code is there already, only pagecache
code is written but not committed).
WL#3072 Maria recovery
* replacing UNDO_ROW_PURGE with CLR_END; testing of those CLR_END via
ma_test2 which has INSERTs failing with duplicate keys.
* replaying of REDO_RENAME_TABLE
Now, off to test Recovery in ha_maria :)
BitKeeper/deleted/.del-ma_least_recently_dirtied.c:
Delete: storage/maria/ma_least_recently_dirtied.c
BitKeeper/deleted/.del-ma_least_recently_dirtied.h:
Delete: storage/maria/ma_least_recently_dirtied.h
storage/maria/Makefile.am:
compile Checkpoint module
storage/maria/ha_maria.cc:
When ha_maria starts, do a recovery from last checkpoint.
Take a checkpoint when that recovery has ended and when ha_maria
shuts down cleanly.
storage/maria/ma_blockrec.c:
* even if my_sync() fails we have to my_close() (otherwise we leak
a descriptor)
* UNDO_ROW_PURGE is replaced by a simple CLR_END for UNDO_ROW_INSERT,
as promised in the old comment; it gives us skipping during the
UNDO phase.
storage/maria/ma_check.c:
All REDOs before create_rename_lsn are ignored by Recovery. So
create_rename_lsn must be set only after all data/index has been
flushed and forced to disk. We thus move write_log_record_for_repair()
to after _ma_flush_tables_files_after_repair().
storage/maria/ma_checkpoint.c:
Checkpoint module.
storage/maria/ma_checkpoint.h:
optional argument if caller wants a thread to periodically take
checkpoints and flush dirty pages.
storage/maria/ma_create.c:
* no need to init some vars as the initial bzero(share) takes care of this.
* update to new function's name
* even if we fail in my_sync() we have to my_close()
storage/maria/ma_extra.c:
Checkpoint reads share->last_version under intern_lock, so we make
maria_extra() update it under intern_lock. THR_LOCK_maria still needed
because of _ma_test_if_reopen().
storage/maria/ma_init.c:
destroy checkpoint module when Maria shuts down.
storage/maria/ma_loghandler.c:
* UNDO_ROW_PURGE gone (see ma_blockrec.c)
* we need to remember the LSN of the LOGREC_FILE_ID for a share,
because this LSN is needed into the checkpoint record (Recovery wants
to know the validity domain of an id->name mapping)
* translog_get_horizon_no_lock() needed for Checkpoint
* comment about failing assertion (Sanja knows)
* translog_init_reader_data() thought that translog_read_record_header_scan()
returns 0 in case of error, but 0 just means "0-length header".
* translog_assign_id_to_share() now needs the MARIA_HA because
LOGREC_FILE_ID uses a log-write hook.
* Verify that (de)assignment of share->id happens only under intern_lock,
as Checkpoint reads this id with intern_lock.
* translog_purge() can accept TRANSLOG_ADDRESS, not necessarily
a real LSN.
storage/maria/ma_loghandler.h:
prototype updates
storage/maria/ma_open.c:
no need to initialize "res"
storage/maria/ma_pagecache.c:
When taking a checkpoint, we don't need to know the maximum rec_lsn
of dirty pages; this LSN was intended to be used in the two-checkpoint
rule, but last_checkpoint_lsn is as good.
4 bytes for stored_list_size is enough as PAGECACHE::blocks (number
of blocks which the pagecache can contain) is int.
storage/maria/ma_pagecache.h:
new prototype
storage/maria/ma_recovery.c:
* added replaying of REDO_RENAME_TABLE
* UNDO_ROW_PURGE gone (see ma_blockrec.c), replaced by CLR_END
* Recovery from the last checkpoint record now possible
* In new_table() we skip the table if the id->name mapping is older than
create_rename_lsn (mapping dates from lsn_of_file_id).
* in get_MARIA_HA_from_REDO_record() we skip the record
if the id->name mapping is newer than the record (can happen if processing
a record which is before the checkpoint record).
* parse_checkpoint_record() has to return a LSN, that's what caller expects
storage/maria/ma_rename.c:
new function's name; log end zeroes of tables' names (ease recovery)
storage/maria/ma_test2.c:
* equivalent of ma_test1's --test-undo added (named -u here).
* -t=1 now stops right after creating the table, so that
we can test undoing of INSERTs with duplicate keys (which tests the
CLR_END logged by _ma_write_abort_block_record()).
storage/maria/ma_test_recovery.expected:
Result of testing undoing of INSERTs with duplicate keys; there are
some differences in maria_chk -dvv but they are normal (removing
records does not shrink data/index file, does not put back the
"analyzed, optimized keys"(etc) index state.
storage/maria/ma_test_recovery:
Test undoing of INSERTs with duplicate keys, using ma_test2;
when such INSERT happens, it logs REDO_INSERT, UNDO_INSERT, REDO_DELETE,
CLR_END; we abort after that, and test that CLR_END causes recovery
to jump over UNDO_INSERT.
storage/maria/ma_write.c:
comment
storage/maria/maria_chk.c:
comment
storage/maria/maria_def.h:
* a new bit in MARIA_SHARE::in_checkpoint, used to build a list
of unique shares during Checkpoint.
* MARIA_SHARE::lsn_of_file_id added: the LSN of the last LOGREC_FILE_ID
for this share; needed to know to which LSN domain the mappings
found in the Checkpoint record apply (new mappings should not apply
to old REDOs).
storage/maria/trnman.c:
* small changes to how trnman_collect_transactions() fills its buffer;
it also uses a non-dummy lsn_read_non_atomic() found in ma_checkpoint.h

Updated results
storage/maria/ma_test_recovery:
Changed tests to use bigger blobs (not just 1K)
Added new tests that tests recovery of update with blobs
Removed comparision of .MAD file as it's not guranteed that recovery from scratch gives identical data file as original update

Use TAIL_PAGE_COUNT_MARKER for tail pages
Set 'sub_blocks' for and only for the head page or for the first extent of a blob. This is needed for store_extent_info() to be able to set START_EXTENT_BIT's
Don't allocate more than 0x3ffff pages in one extent (We need bit 0x4000 as a START_EXTENT_BIT)
Increase the calculated 'head_length' with the number of bytes used for extents.

Use PAGE_COUNT to mark if an extent is the start of of a blob. (Needed for extent_to_bitmap_blocks())
Added check_directory() for checking that directroy entries are correct.
Added checking of row checksums when reading rows (with EXTRA_DEBUG)
Added make_space_for_directory() and extend_directory() for doing expansion of directory

Changed _ma_apply_undo_row_delete() and _ma_apply_undo_row_update() to put row in it's original position
Ensure allocation of tail blocks are of at least MIN_TAIL_SIZE.
Ensure we store pages in pinned pages even if read failed. (If not we will have pages pinned forever in page cache)
Write original extent information in UNDO entry, not compacted ones (we need position to tails!)
When setting BLOCKUSED_USED, don't clear other bits (we have to preserve BLOCKUSED_USE_ORG_BITMAP)

Make _ma_bitmap_get_page_bits() global. (Needed for UNDO handling)
Changed _ma_bitmap_flushable() to take MARIA_HA instead of MARIA_SHARE.
This was needed to be able to mark the handler if we had a 'non_flushable' call pending or not.
Don't use 'non_flushable' marking of bitmap pages for not transactional tables.
Added BLOCKUSED_USE_ORG_BITMAP handling also for tail pages.
Added more DBUG_ASSERT() to find possible errors in other code
Some code simplications by adding new local variables
storage/maria/ma_blockrec.c:
UNDO of rows now puts back all part of the row on their original pages and positions.
Changed UNDO of DELETE and UNDO of UPDATE to contain information about the original length of data on head block and also extent information
This changes a lot of logic as now an insert of a row on a page may happen to any position (and not just to the first or next free)
Use PAGE_COUNT to mark if an extent is the start of of a blob. (Needed for extent_to_bitmap_blocks())
Added check_directory() for checking that directroy entries are correct.
Added checking of row checksums when reading rows (with EXTRA_DEBUG)
Added make_space_for_directory() and extend_directory() for doing expansion of directory

Changed _ma_apply_undo_row_delete() and _ma_apply_undo_row_update() to put row in it's original position
Ensure allocation of tail blocks are of at least MIN_TAIL_SIZE.
Ensure we store pages in pinned pages even if read failed. (If not we will have pages pinned forever in page cache)
Write original extent information in UNDO entry, not compacted ones (we need position to tails!)
When setting BLOCKUSED_USED, don't clear other bits (we have to preserve BLOCKUSED_USE_ORG_BITMAP)
Fixed som bugs in directory handling
Fixed bug where we wrote wrong lsn to blob pages
Added separate blob_buffer for fixing bug when updating row that had char/varchar that spanned several pages and also had blobs
Ensure we call _ma_bitmap_flushable() also in case of errors

Updated results
storage/maria/ma_test_recovery:
Changed tests to use bigger blobs (not just 1K)
Added new tests that tests recovery of update with blobs

Simplify code (changed * to if)
storage/maria/maria_chk.c:
Make output more readable
storage/maria/maria_def.h:

WL#3072 - Maria Recovery
Bulk insert: don't log REDO/UNDO for rows, log one UNDO which will
truncate files; this is an optimization and a bugfix (table was left
half-repaired by crash).
Repair: mark table crashed-on-repair at start, bump skip_redo_lsn at start,
this is easier for recovery (tells it to skip old REDOs or even UNDO
phase) and user (tells it to repair) in case of crash, sync files
in the end.
Recovery skips missing or corrupted table and moves to next record
(in REDO or UNDO phase) to be more robust; warns if happens in UNDO phase.
Bugfix for UNDO_KEY_DELETE_WITH_ROOT (tested in ma_test_recovery)
and maria_enable_indexes().
Create missing bitmaps when needed (there can be more than one to create,
in rare cases), log a record for this.
include/myisamchk.h:
new flag: bulk insert repair mustn't bump create_rename_lsn
mysql-test/lib/mtr_report.pl:
skip normal warning in maria-recovery.test
mysql-test/r/maria-recovery.result:
result: crash before bulk insert is committed, causes proper rollback,
and crash right after OPTIMIZE replaces index file with new index file
leads to table marked corrupted and recovery not failing.
mysql-test/t/maria-recovery.test:
- can't check the table or it would commit the transaction,
but check is made after recovery.
- test of crash before bulk-insert-with-repair is committed
(to see if it is rolled back), and of crash after OPTIMIZE has replaced
index file but not finished all operations (to see if recovery fails -
it used to assert when trying to execute an old REDO on the new
index).
storage/maria/CMakeLists.txt:
new file
storage/maria/Makefile.am:
new file
storage/maria/ha_maria.cc:
- If bulk insert on a transactional table using an index repair:
table is initially empty, so don't log REDO/UNDO for data rows
(optimization), just log an UNDO_BULK_INSERT_WITH_REPAIR
which will, if executed, empty the data and index file. Re-enable
logging in end_bulk_insert().
- write log record for repair operation only after it's fully done,
index sort including (maria_repair*() used to write the log record).
- Adding back file->trn=NULL which was removed by mistake earlier.
storage/maria/ha_maria.h:
new member (see ha_maria.cc)
storage/maria/ma_bitmap.c:
Functions to create missing bitmaps:
- one function which creates missing bitmaps in page cache, except
the missing one with max offset which it does not put into page cache
as it will be modified very soon.
- one function which the one above calls, and creates bitmaps in page
cache
- one function to execute REDO_BITMAP_NEW_PAGE which uses the second
one above.
storage/maria/ma_blockrec.c:
- when logging REDO_DELETE_ALL, not only 'records' and 'checksum'
has to be reset under log's mutex.
- execution of REDO_INSERT_ROW_BLOBS now checks the dirty pages' list
- execution of UNDO_BULK_INSERT_WITH_REPAIR
storage/maria/ma_blockrec.h:
new functions
storage/maria/ma_check.c:
- table-flush-before-repair is moved to a separate function reused
by maria_sort_index(); syncing is added
- maria_repair() is allowed to re-enable logging only if it is the one
which disabled it.
- "_ma_flush_table_files_after_repair" was a bad name, it's not after
repair now, and it should not sync as we do more changes to the files
shortly after (sync is postponed to when writing the log record)
- REDO_REPAIR record should be written only after all repair
operations (in particular after sorting index in ha_mara::repair())
- close to the end of repair by sort, flushing of pages must happen
also in the non-quick case, to prepare for the sync at end.
- in parallel repair, some page flushes are not needed as done
by initialize_variables_for_repair().
storage/maria/ma_create.c:
Update skip_redo_lsn, create_rename_lsn optionally.
storage/maria/ma_delete_all.c:
Need to sync files at end of maria_delete_all_rows(), if transactional.
storage/maria/ma_extra.c:
During repair, we sometimes call _ma_flush_table_files() (via
_ma_flush_table_files_before_swap()) while there is a WRITE_CACHE.
storage/maria/ma_key_recover.c:
- when we see CLR_END for UNDO_BULK_INSERT_WITH_REPAIR, re-enable
indices.
- fixing bug: _ma_apply_undo_key_delete() parsed UNDO_KEY_DELETE_WITH_ROOT
wrongly, leading to recovery failure
storage/maria/ma_key_recover.h:
new prototype
storage/maria/ma_locking.c:
DBUG_VOID_RETURN missing
storage/maria/ma_loghandler.c:
UNDO for bulk insert with repair, and REDO for creating bitmaps.
LOGREC_FIRST_FREE to not have to change the for() every time we
add a new record type.
storage/maria/ma_loghandler.h:
new UNDO and REDO
storage/maria/ma_open.c:
Move share.kfile.file=kfile up a bit, so that _ma_update_state_lsns()
can get its value, this fixes a bug where LSN_REPAIRED_BY_MARIA_CHK
was not corrected on disk by maria_open().
Store skip_redo_lsn in index' header.
maria_enable_indexes() had a bug for BLOCK_RECORD, where an empty
file has one page, not 0 bytes.
storage/maria/ma_recovery.c:
- Skip a corrupted, missing, or repaired-with-maria_chk, table in
recovery: don't fail, just go to next REDO or UNDO; but if an UNDO
is skipped in UNDO phase we issue warnings.
- Skip REDO|UNDO in REDO phase if <skip_redo_lsn.
- If UNDO phase fails, delete transactions to not make trnman
assert.
- Update skip_redo_lsn when playing REDO_CREATE_TABLE
- Don't record UNDOs for old transactions which we don't know (long_trid==0)
- Bugfix for UNDO_KEY_DELETE_WITH_ROOT (see ma_key_recover.c)
- Execution of UNDO_BULK_INSERT_WITH_REPAIR
- Don't try to find a page number in REDO_DELETE_ALL
- Pieces moved to ma_recovery_util.c
storage/maria/ma_rename.c:
name change
storage/maria/ma_static.c:
I modified layout of the index' header (inserted skip_redo_lsn in its middle)
storage/maria/ma_test2.c:
allow breaking the test towards the end, tests execution of
UNDO_KEY_DELETE_WITH_ROOT
storage/maria/ma_test_recovery.expected:
6 as testflag instead of 4
storage/maria/ma_test_recovery:
Increase the amount of rollback work to do when testing recovery
with ma_test2; this reproduces the UNDO_KEY_DELETE_WITH_ROOT bug.
storage/maria/maria_chk.c:
skip_redo_lsn should be updated too, for consistency.
Write a REDO_REPAIR after all operations (including sort-records)
have been done.
No reason to flush blocks after maria_chk_data_link() and
maria_sort_records(), there is maria_close() in the end.
write_log_record() is a function, to not clutter maria_chk().
storage/maria/maria_def.h:
New member skip_redo_lsn in the state, and comments
storage/maria/maria_pack.c:
skip_redo_lsn should be updated too, for consistency
storage/maria/ma_recovery_util.c:
_ma_redo_not_needed_for_page(), defined in ma_recovery.c, is needed
by ma_blockrec.c; this causes link issues, resolved by putting
_ma_redo_not_needed_for_page() into a new file (so that it is not
in the same file as repair-related objects of ma_recovery.c).

WL#3071 Maria checkpoint
Ability for flush_pagecache_blocks() to flush only certain pages of
a file, as instructed by an option "filter" pointer-to-function argument;
Checkpoint and background dirty page flushing use that to flush only
pages which have been dirty for long enough and bitmap pages.
Fix for a bug in flush_cached_blocks() (no idea if it could produce
a bug in real life, but theoretically it is).
Testing checkpoint in ma_test_recovery via ma_test1 and ma_test2.
Background checkpoint & dirty pages flush thread is still disabled
by default in ha_maria.
mysql-test/r/maria.result:
result update
storage/maria/ha_maria.cc:
blank after function comment
storage/maria/ma_checkpoint.c:
Using an enum instead of 0/1/2 (applying Sanja's review comments).
The comment about "this is an horizon" can be removed as Sanja
created translog_next_LSN() which parse_checkpoint_record() uses.
Variables in ma_checkpoint_background() cannot be declared in the
for() as their value must not be reset at each iteration!
storage/maria/ma_pagecache.c:
adding to flush_pagecache_blocks() optional arguments 'filter'
(pointer to function) and 'filter_arg'; if filter!=NULL this function
will be called for each block of the file and will reply if this
block and following ones should be flushed or not (3 possible
replies).
Fixing a bug when flush_cached_blocks() skips a pinned page: it has
to unset PCBLOCK_IN_FLUSH set by flush_pagecache_blocks_int().
storage/maria/ma_pagecache.h:
flush_pagecache_blocks() is changed to take "filter" and "filter_arg"
arguments. "filter", if it is not NULL, may return one value
among enum pagecache_flush_filter_result.
storage/maria/ma_recovery.c:
open_count=0 when closing tables at the end of recovery.
storage/maria/ma_test1.c:
Optional checkpoints (-H#) at various stages (stages similar
to --testflag), for testing of checkpoints.
storage/maria/ma_test2.c:
Optional checkpoints (-H#) at various stages (stages similar
to -t), for testing of checkpoints.
storage/maria/ma_test_recovery.expected:
Result update: the results of the additional test run with -H#
(checkpoints) are added here. They are exactly identical to without
checkpoints except that the index's Root (printed by maria_chk)
is more correct when using checkpoints. This is because checkpoint
flushed the state, so it happens to be correct, while no-checkpoint
does not flush the state, and recovery does not recover indexes
so Root is never fixed. When we recover indices, this will go away.
storage/maria/ma_test_recovery:
We duplicate the loop of tests to add an additional run with
checkpoints at various stages, to see if maria_read_log
uses them fine.

Added versioning of row data
Will in future changeset (soon) av versioning of status variables (number of rows) and index
Changed some LEX_STRING to LEX_CUSTRING to avoid casts and warnings
Removed some not needed variables (as noticed by Guilhem)
include/maria.h:
Added prototypes for maria_chk_init_for_check(), maria_versioning() and maria_ignore_trids()
include/my_base.h:
Add new error HA_ERR_ROW_NOT_VISIBLE
include/myisamchk.h:
Added variables for checking visibility of rows during maria_chk
include/thr_lock.h:
Changed argument type from int to my_bool for get_status
Added variable allow_multiple_concurrent_insert, to signal if table supports multiple concurrent inserts
mysql-test/r/maria-page-checksum.result:
Added missing drop table
mysql-test/t/maria-page-checksum.test:
Added missing drop table
mysys/my_handler.c:
Added new error messages
mysys/thr_lock.c:
Added support for multiple concurrent inserts, if table handler supports it
sql/sql_yacc.yy:

WL#3071 Maria checkpoint
Ability for flush_pagecache_blocks() to flush only certain pages of
a file, as instructed by an option "filter" pointer-to-function argument;
Checkpoint and background dirty page flushing use that to flush only
pages which have been dirty for long enough and bitmap pages.
Fix for a bug in flush_cached_blocks() (no idea if it could produce
a bug in real life, but theoretically it is).
Testing checkpoint in ma_test_recovery via ma_test1 and ma_test2.
Background checkpoint & dirty pages flush thread is still disabled
by default in ha_maria.
mysql-test/r/maria.result:
result update
storage/maria/ha_maria.cc:
blank after function comment
storage/maria/ma_checkpoint.c:
Using an enum instead of 0/1/2 (applying Sanja's review comments).
The comment about "this is an horizon" can be removed as Sanja
created translog_next_LSN() which parse_checkpoint_record() uses.
Variables in ma_checkpoint_background() cannot be declared in the
for() as their value must not be reset at each iteration!
storage/maria/ma_pagecache.c:
adding to flush_pagecache_blocks() optional arguments 'filter'
(pointer to function) and 'filter_arg'; if filter!=NULL this function
will be called for each block of the file and will reply if this
block and following ones should be flushed or not (3 possible
replies).
Fixing a bug when flush_cached_blocks() skips a pinned page: it has
to unset PCBLOCK_IN_FLUSH set by flush_pagecache_blocks_int().
storage/maria/ma_pagecache.h:
flush_pagecache_blocks() is changed to take "filter" and "filter_arg"
arguments. "filter", if it is not NULL, may return one value
among enum pagecache_flush_filter_result.
storage/maria/ma_recovery.c:
open_count=0 when closing tables at the end of recovery.
storage/maria/ma_test1.c:
Optional checkpoints (-H#) at various stages (stages similar
to --testflag), for testing of checkpoints.
storage/maria/ma_test2.c:
Optional checkpoints (-H#) at various stages (stages similar
to -t), for testing of checkpoints.
storage/maria/ma_test_recovery.expected:
Result update: the results of the additional test run with -H#
(checkpoints) are added here. They are exactly identical to without
checkpoints except that the index's Root (printed by maria_chk)
is more correct when using checkpoints. This is because checkpoint
flushed the state, so it happens to be correct, while no-checkpoint
does not flush the state, and recovery does not recover indexes
so Root is never fixed. When we recover indices, this will go away.
storage/maria/ma_test_recovery:
We duplicate the loop of tests to add an additional run with
checkpoints at various stages, to see if maria_read_log
uses them fine.

Added _ma_bitmap_wait_or_flush() to cause reader of bitmap pages to wait with reading until bitmap is flushed.
Use TAIL_PAGE_COUNT_MARKER for tail pages
Set 'sub_blocks' for and only for the head page or for the first extent of a blob. This is needed for store_extent_info() to be able to set START_EXTENT_BIT's

Fixed som bugs in directory handling
Fixed bug where we wrote wrong lsn to blob pages
Added separate blob_buffer for fixing bug when updating row that had char/varchar that spanned several pages and also had blobs

First created blob is now of max blob length to ensure we have at least one big blob in the table
storage/maria/ma_test_all.sh:
More tests
storage/maria/ma_test_recovery.expected:
Updated results
storage/maria/ma_test_recovery:
Changed tests to use bigger blobs (not just 1K)
Added new tests that tests recovery of update with blobs
Removed comparision of .MAD file as it's not guranteed that recovery from scratch gives identical data file as original update

Simplify code (changed * to if)
storage/maria/maria_chk.c:
Make output more readable

Use TAIL_PAGE_COUNT_MARKER for tail pages
Set 'sub_blocks' for and only for the head page or for the first extent of a blob. This is needed for store_extent_info() to be able to set START_EXTENT_BIT's
Don't allocate more than 0x3ffff pages in one extent (We need bit 0x4000 as a START_EXTENT_BIT)
Increase the calculated 'head_length' with the number of bytes used for extents.

Use PAGE_COUNT to mark if an extent is the start of of a blob. (Needed for extent_to_bitmap_blocks())
Added check_directory() for checking that directroy entries are correct.
Added checking of row checksums when reading rows (with EXTRA_DEBUG)
Added make_space_for_directory() and extend_directory() for doing expansion of directory

Changed _ma_apply_undo_row_delete() and _ma_apply_undo_row_update() to put row in it's original position
Ensure allocation of tail blocks are of at least MIN_TAIL_SIZE.
Ensure we store pages in pinned pages even if read failed. (If not we will have pages pinned forever in page cache)
Write original extent information in UNDO entry, not compacted ones (we need position to tails!)
When setting BLOCKUSED_USED, don't clear other bits (we have to preserve BLOCKUSED_USE_ORG_BITMAP)
Fixed som bugs in directory handling
Fixed bug where we wrote wrong lsn to blob pages
Added separate blob_buffer for fixing bug when updating row that had char/varchar that spanned several pages and also had blobs
Ensure we call _ma_bitmap_flushable() also in case of errors

Info->s -> share
Rowid -> rowid
More DBUG_ASSERT()

UNDO of rows now puts back all part of the row on their original pages and positions
Added variable _dbug_on_ to speed up execution when DBUG is not going to be used
Added --debug-on option to mysqld (to be able to turn of DBUG with --debug-on=0)
Fixed some bugs with 'non_flushable' marking of bitmap pages
Don't use 'non_flushable' marking of bitmap pages for not transactional tables
SHOW CREATE TABLE now shows if table was created with page checksums
Fixed a lot of bugs with BLOB handling in case of update/REDO and UNDO
More tests (especially for blobs) and DBUG_ASSERTS()
More readable output from maria_read_log and maria_chk
Fixed wrong shift that caused Maria to crash on files > 4G
Mark tables as crashed of REDO fails
dbug/dbug.c:
Changed to use my_bool (allowed me to remove some windows specific code)
Added variable _dbug_on_ to speed up execution when DBUG is not going to be used
Removed initialization of variables if not needed
include/my_dbug.h:
Use my_bool for some functions that was defined as BOOLEAN in dbug.c code

Define my_bool early
Increase MY_HOW_OFTEN_TO_WRITE as computers are now faster than 10 years ago

storage/maria/ha_maria.cc:
Store in create_info if page checksums are used (For SHOW CREATE TABLE)
storage/maria/ma_bitmap.c:
Added _ma_bitmap_wait_or_flush() to cause reader of bitmap pages to wait with reading until bitmap is flushed.
Use TAIL_PAGE_COUNT_MARKER for tail pages
Set 'sub_blocks' for and only for the head page or for the first extent of a blob. This is needed for store_extent_info() to be able to set START_EXTENT_BIT's
Don't allocate more than 0x3ffff pages in one extent (We need bit 0x4000 as a START_EXTENT_BIT)
Increase the calculated 'head_length' with the number of bytes used for extents.
Update row->space_on_head_page also in _ma_bitmap_find_new_place()
Make _ma_bitmap_get_page_bits() global. (Needed for UNDO handling)

This changes a lot of logic as now an insert of a row on a page may happen to any position (and not just to the first or next free)
Use PAGE_COUNT to mark if an extent is the start of of a blob. (Needed for extent_to_bitmap_blocks())
Added check_directory() for checking that directroy entries are correct.
Added checking of row checksums when reading rows (with EXTRA_DEBUG)
Added make_space_for_directory() and extend_directory() for doing expansion of directory

WL#3072 - Maria Recovery
Bulk insert: don't log REDO/UNDO for rows, log one UNDO which will
truncate files; this is an optimization and a bugfix (table was left
half-repaired by crash).
Repair: mark table crashed-on-repair at start, bump skip_redo_lsn at start,
this is easier for recovery (tells it to skip old REDOs or even UNDO
phase) and user (tells it to repair) in case of crash, sync files
in the end.
Recovery skips missing or corrupted table and moves to next record
(in REDO or UNDO phase) to be more robust; warns if happens in UNDO phase.
Bugfix for UNDO_KEY_DELETE_WITH_ROOT (tested in ma_test_recovery)
and maria_enable_indexes().
Create missing bitmaps when needed (there can be more than one to create,
in rare cases), log a record for this.
include/myisamchk.h:
new flag: bulk insert repair mustn't bump create_rename_lsn
mysql-test/lib/mtr_report.pl:
skip normal warning in maria-recovery.test
mysql-test/r/maria-recovery.result:
result: crash before bulk insert is committed, causes proper rollback,
and crash right after OPTIMIZE replaces index file with new index file
leads to table marked corrupted and recovery not failing.
mysql-test/t/maria-recovery.test:
- can't check the table or it would commit the transaction,
but check is made after recovery.
- test of crash before bulk-insert-with-repair is committed
(to see if it is rolled back), and of crash after OPTIMIZE has replaced
index file but not finished all operations (to see if recovery fails -
it used to assert when trying to execute an old REDO on the new
index).
storage/maria/CMakeLists.txt:
new file
storage/maria/Makefile.am:
new file
storage/maria/ha_maria.cc:
- If bulk insert on a transactional table using an index repair:
table is initially empty, so don't log REDO/UNDO for data rows
(optimization), just log an UNDO_BULK_INSERT_WITH_REPAIR
which will, if executed, empty the data and index file. Re-enable
logging in end_bulk_insert().
- write log record for repair operation only after it's fully done,
index sort including (maria_repair*() used to write the log record).
- Adding back file->trn=NULL which was removed by mistake earlier.
storage/maria/ha_maria.h:
new member (see ha_maria.cc)
storage/maria/ma_bitmap.c:
Functions to create missing bitmaps:
- one function which creates missing bitmaps in page cache, except
the missing one with max offset which it does not put into page cache
as it will be modified very soon.
- one function which the one above calls, and creates bitmaps in page
cache
- one function to execute REDO_BITMAP_NEW_PAGE which uses the second
one above.
storage/maria/ma_blockrec.c:
- when logging REDO_DELETE_ALL, not only 'records' and 'checksum'
has to be reset under log's mutex.
- execution of REDO_INSERT_ROW_BLOBS now checks the dirty pages' list
- execution of UNDO_BULK_INSERT_WITH_REPAIR
storage/maria/ma_blockrec.h:
new functions
storage/maria/ma_check.c:
- table-flush-before-repair is moved to a separate function reused
by maria_sort_index(); syncing is added
- maria_repair() is allowed to re-enable logging only if it is the one
which disabled it.
- "_ma_flush_table_files_after_repair" was a bad name, it's not after
repair now, and it should not sync as we do more changes to the files
shortly after (sync is postponed to when writing the log record)
- REDO_REPAIR record should be written only after all repair
operations (in particular after sorting index in ha_mara::repair())
- close to the end of repair by sort, flushing of pages must happen
also in the non-quick case, to prepare for the sync at end.
- in parallel repair, some page flushes are not needed as done
by initialize_variables_for_repair().
storage/maria/ma_create.c:
Update skip_redo_lsn, create_rename_lsn optionally.
storage/maria/ma_delete_all.c:
Need to sync files at end of maria_delete_all_rows(), if transactional.
storage/maria/ma_extra.c:
During repair, we sometimes call _ma_flush_table_files() (via
_ma_flush_table_files_before_swap()) while there is a WRITE_CACHE.
storage/maria/ma_key_recover.c:
- when we see CLR_END for UNDO_BULK_INSERT_WITH_REPAIR, re-enable
indices.
- fixing bug: _ma_apply_undo_key_delete() parsed UNDO_KEY_DELETE_WITH_ROOT
wrongly, leading to recovery failure
storage/maria/ma_key_recover.h:
new prototype
storage/maria/ma_locking.c:
DBUG_VOID_RETURN missing
storage/maria/ma_loghandler.c:
UNDO for bulk insert with repair, and REDO for creating bitmaps.
LOGREC_FIRST_FREE to not have to change the for() every time we
add a new record type.
storage/maria/ma_loghandler.h:
new UNDO and REDO
storage/maria/ma_open.c:
Move share.kfile.file=kfile up a bit, so that _ma_update_state_lsns()
can get its value, this fixes a bug where LSN_REPAIRED_BY_MARIA_CHK
was not corrected on disk by maria_open().
Store skip_redo_lsn in index' header.
maria_enable_indexes() had a bug for BLOCK_RECORD, where an empty
file has one page, not 0 bytes.
storage/maria/ma_recovery.c:
- Skip a corrupted, missing, or repaired-with-maria_chk, table in
recovery: don't fail, just go to next REDO or UNDO; but if an UNDO
is skipped in UNDO phase we issue warnings.
- Skip REDO|UNDO in REDO phase if <skip_redo_lsn.
- If UNDO phase fails, delete transactions to not make trnman
assert.
- Update skip_redo_lsn when playing REDO_CREATE_TABLE
- Don't record UNDOs for old transactions which we don't know (long_trid==0)
- Bugfix for UNDO_KEY_DELETE_WITH_ROOT (see ma_key_recover.c)
- Execution of UNDO_BULK_INSERT_WITH_REPAIR
- Don't try to find a page number in REDO_DELETE_ALL
- Pieces moved to ma_recovery_util.c
storage/maria/ma_rename.c:
name change
storage/maria/ma_static.c:
I modified layout of the index' header (inserted skip_redo_lsn in its middle)
storage/maria/ma_test2.c:
allow breaking the test towards the end, tests execution of
UNDO_KEY_DELETE_WITH_ROOT
storage/maria/ma_test_recovery.expected:
6 as testflag instead of 4
storage/maria/ma_test_recovery:
Increase the amount of rollback work to do when testing recovery
with ma_test2; this reproduces the UNDO_KEY_DELETE_WITH_ROOT bug.
storage/maria/maria_chk.c:
skip_redo_lsn should be updated too, for consistency.
Write a REDO_REPAIR after all operations (including sort-records)
have been done.
No reason to flush blocks after maria_chk_data_link() and
maria_sort_records(), there is maria_close() in the end.
write_log_record() is a function, to not clutter maria_chk().
storage/maria/maria_def.h:
New member skip_redo_lsn in the state, and comments
storage/maria/maria_pack.c:
skip_redo_lsn should be updated too, for consistency
storage/maria/ma_recovery_util.c:
_ma_redo_not_needed_for_page(), defined in ma_recovery.c, is needed
by ma_blockrec.c; this causes link issues, resolved by putting
_ma_redo_not_needed_for_page() into a new file (so that it is not
in the same file as repair-related objects of ma_recovery.c).
storage/maria/ma_recovery_util.h:
new file

WL#3071 Maria checkpoint
Ability for flush_pagecache_blocks() to flush only certain pages of
a file, as instructed by an option "filter" pointer-to-function argument;
Checkpoint and background dirty page flushing use that to flush only
pages which have been dirty for long enough and bitmap pages.
Fix for a bug in flush_cached_blocks() (no idea if it could produce
a bug in real life, but theoretically it is).
Testing checkpoint in ma_test_recovery via ma_test1 and ma_test2.
Background checkpoint & dirty pages flush thread is still disabled
by default in ha_maria.
mysql-test/r/maria.result:
result update
storage/maria/ha_maria.cc:
blank after function comment
storage/maria/ma_checkpoint.c:
Using an enum instead of 0/1/2 (applying Sanja's review comments).
The comment about "this is an horizon" can be removed as Sanja
created translog_next_LSN() which parse_checkpoint_record() uses.
Variables in ma_checkpoint_background() cannot be declared in the
for() as their value must not be reset at each iteration!
storage/maria/ma_pagecache.c:
adding to flush_pagecache_blocks() optional arguments 'filter'
(pointer to function) and 'filter_arg'; if filter!=NULL this function
will be called for each block of the file and will reply if this
block and following ones should be flushed or not (3 possible
replies).
Fixing a bug when flush_cached_blocks() skips a pinned page: it has
to unset PCBLOCK_IN_FLUSH set by flush_pagecache_blocks_int().
storage/maria/ma_pagecache.h:
flush_pagecache_blocks() is changed to take "filter" and "filter_arg"
arguments. "filter", if it is not NULL, may return one value
among enum pagecache_flush_filter_result.
storage/maria/ma_recovery.c:
open_count=0 when closing tables at the end of recovery.
storage/maria/ma_test1.c:
Optional checkpoints (-H#) at various stages (stages similar
to --testflag), for testing of checkpoints.
storage/maria/ma_test2.c:
Optional checkpoints (-H#) at various stages (stages similar
to -t), for testing of checkpoints.
storage/maria/ma_test_recovery.expected:
Result update: the results of the additional test run with -H#
(checkpoints) are added here. They are exactly identical to without
checkpoints except that the index's Root (printed by maria_chk)
is more correct when using checkpoints. This is because checkpoint
flushed the state, so it happens to be correct, while no-checkpoint
does not flush the state, and recovery does not recover indexes
so Root is never fixed. When we recover indices, this will go away.
storage/maria/ma_test_recovery:
We duplicate the loop of tests to add an additional run with
checkpoints at various stages, to see if maria_read_log
uses them fine.

WL#3071 Maria checkpoint
Ability for flush_pagecache_blocks() to flush only certain pages of
a file, as instructed by an option "filter" pointer-to-function argument;
Checkpoint and background dirty page flushing use that to flush only
pages which have been dirty for long enough and bitmap pages.
Fix for a bug in flush_cached_blocks() (no idea if it could produce
a bug in real life, but theoretically it is).
Testing checkpoint in ma_test_recovery via ma_test1 and ma_test2.
Background checkpoint & dirty pages flush thread is still disabled
by default in ha_maria.
mysql-test/r/maria.result:
result update
storage/maria/ha_maria.cc:
blank after function comment
storage/maria/ma_checkpoint.c:
Using an enum instead of 0/1/2 (applying Sanja's review comments).
The comment about "this is an horizon" can be removed as Sanja
created translog_next_LSN() which parse_checkpoint_record() uses.
Variables in ma_checkpoint_background() cannot be declared in the
for() as their value must not be reset at each iteration!
storage/maria/ma_pagecache.c:
adding to flush_pagecache_blocks() optional arguments 'filter'
(pointer to function) and 'filter_arg'; if filter!=NULL this function
will be called for each block of the file and will reply if this
block and following ones should be flushed or not (3 possible
replies).
Fixing a bug when flush_cached_blocks() skips a pinned page: it has
to unset PCBLOCK_IN_FLUSH set by flush_pagecache_blocks_int().
storage/maria/ma_pagecache.h:
flush_pagecache_blocks() is changed to take "filter" and "filter_arg"
arguments. "filter", if it is not NULL, may return one value
among enum pagecache_flush_filter_result.
storage/maria/ma_recovery.c:
open_count=0 when closing tables at the end of recovery.
storage/maria/ma_test1.c:
Optional checkpoints (-H#) at various stages (stages similar
to --testflag), for testing of checkpoints.
storage/maria/ma_test2.c:
Optional checkpoints (-H#) at various stages (stages similar
to -t), for testing of checkpoints.
storage/maria/ma_test_recovery.expected:
Result update: the results of the additional test run with -H#
(checkpoints) are added here. They are exactly identical to without
checkpoints except that the index's Root (printed by maria_chk)
is more correct when using checkpoints. This is because checkpoint
flushed the state, so it happens to be correct, while no-checkpoint
does not flush the state, and recovery does not recover indexes
so Root is never fixed. When we recover indices, this will go away.
storage/maria/ma_test_recovery:
We duplicate the loop of tests to add an additional run with
checkpoints at various stages, to see if maria_read_log
uses them fine.

UNDO of rows now puts back all part of the row on their original pages and positions
Added variable _dbug_on_ to speed up execution when DBUG is not going to be used
Added --debug-on option to mysqld (to be able to turn of DBUG with --debug-on=0)
Fixed some bugs with 'non_flushable' marking of bitmap pages
Don't use 'non_flushable' marking of bitmap pages for not transactional tables
SHOW CREATE TABLE now shows if table was created with page checksums
Fixed a lot of bugs with BLOB handling in case of update/REDO and UNDO
More tests (especially for blobs) and DBUG_ASSERTS()
More readable output from maria_read_log and maria_chk
Fixed wrong shift that caused Maria to crash on files > 4G
Mark tables as crashed of REDO fails
dbug/dbug.c:
Changed to use my_bool (allowed me to remove some windows specific code)
Added variable _dbug_on_ to speed up execution when DBUG is not going to be used
Removed initialization of variables if not needed
include/my_dbug.h:
Use my_bool for some functions that was defined as BOOLEAN in dbug.c code
Added DBUGGER_ON/DEBUGGER_OFF to speed up execution when DBUG is not used
include/my_global.h:
Define my_bool early
Increase MY_HOW_OFTEN_TO_WRITE as computers are now faster than 10 years ago
mysql-test/mysql-test-run.pl:
Added debug-on=0 to speed up tests
mysql-test/r/maria-recovery.result:
Added new test by Guilhem to test if UNDO_ROW_DELETE preserves rowid
mysql-test/r/maria.result:

Added --debug-on option (to be able to turn of DBUG with --debug-on=0)
Indentation fixes
Removed end spaces
sql/sql_show.cc:
Allow update_create_info() to inform MySQL if PACK_KEYS, NO_PACK_KEYS, CHECKSUM, PAGE_CHECKSUM or DELAY_KEY_WRITE is used
storage/maria/Makefile.am:
Added ma_test_big.sh
storage/maria/ha_maria.cc:
Store in create_info if page checksums are used (For SHOW CREATE TABLE)
storage/maria/ma_bitmap.c:
Added _ma_bitmap_wait_or_flush() to cause reader of bitmap pages to wait with reading until bitmap is flushed.
Use TAIL_PAGE_COUNT_MARKER for tail pages
Set 'sub_blocks' for and only for the head page or for the first extent of a blob. This is needed for store_extent_info() to be able to set START_EXTENT_BIT's
Don't allocate more than 0x3ffff pages in one extent (We need bit 0x4000 as a START_EXTENT_BIT)
Increase the calculated 'head_length' with the number of bytes used for extents.
Update row->space_on_head_page also in _ma_bitmap_find_new_place()
Make _ma_bitmap_get_page_bits() global. (Needed for UNDO handling)
Changed _ma_bitmap_flushable() to take MARIA_HA instead of MARIA_SHARE.
This was needed to be able to mark the handler if we had a 'non_flushable' call pending or not.
Don't use 'non_flushable' marking of bitmap pages for not transactional tables.
Added BLOCKUSED_USE_ORG_BITMAP handling also for tail pages.
Added more DBUG_ASSERT() to find possible errors in other code
Some code simplications by adding new local variables
storage/maria/ma_blockrec.c:
UNDO of rows now puts back all part of the row on their original pages and positions.
Changed UNDO of DELETE and UNDO of UPDATE to contain information about the original length of data on head block and also extent information
This changes a lot of logic as now an insert of a row on a page may happen to any position (and not just to the first or next free)
Use PAGE_COUNT to mark if an extent is the start of of a blob. (Needed for extent_to_bitmap_blocks())
Added check_directory() for checking that directroy entries are correct.
Added checking of row checksums when reading rows (with EXTRA_DEBUG)
Added make_space_for_directory() and extend_directory() for doing expansion of directory
Added get_rowpos_in_head_or_tail_page() to be able to store head/tail on original position in UNDO

Added _ma_update_at_original_place() for UNDO of DELETES
Added row->min_length to hold minmum required space needed on head page
Changed find_free_position() to use make_space_for_directory()
Changed make_empty_page() to allow optional creation of directory entry
Changed delete_head_or_tail() and _ma_apply_undo_row_isnert() to not copy pagecache block (speed optimization)
Changed _ma_apply_redo_insert_row_head_or_tail() to be able to insert new row at any position on 'new' page
Changed _ma_apply_undo_row_delete() and _ma_apply_undo_row_update() to put row in it's original position
Ensure allocation of tail blocks are of at least MIN_TAIL_SIZE.
Ensure we store pages in pinned pages even if read failed. (If not we will have pages pinned forever in page cache)
Write original extent information in UNDO entry, not compacted ones (we need position to tails!)
When setting BLOCKUSED_USED, don't clear other bits (we have to preserve BLOCKUSED_USE_ORG_BITMAP)
Fixed som bugs in directory handling
Fixed bug where we wrote wrong lsn to blob pages
Added separate blob_buffer for fixing bug when updating row that had char/varchar that spanned several pages and also had blobs
Ensure we call _ma_bitmap_flushable() also in case of errors
When doing an update, first delete old entries, then search in bitmap for where to put new information
Info->s -> share
Rowid -> rowid
More DBUG_ASSERT()
storage/maria/ma_blockrec.h:
Added START_EXTENT_BIT and TAIL_PAGE_COUNT_MARKER
Added _ma_bitmap_wait_or_flush() and _ma_bitmap_get_page_bits()
storage/maria/ma_check.c:
Don't write extra empty line if there is no deleted blocks
Ignore START_EXTENT_BIT's in page count
Call _ma_fast_unlock_key_del() to free key_del link
storage/maria/ma_close.c:
Ensure that used_key_del is 0. (If not, someone forgot to call _ma_unlock_key_del())
storage/maria/ma_create.c:
Changed constant to macro
storage/maria/ma_delete.c:
For deleted keys, log also position to row
storage/maria/ma_extra.c:
Release blob buffer at maria_reset() if bigger than MARIA_SMALL_BLOB_BUFFER
storage/maria/ma_key_recover.c:
Added bzero() of LSN that confused paged cache in case of uninitialized block
Mark file crashed if applying of index changes fails
Added calls to _ma_fast_unlock_key_del() for protection of shared key_del link.
storage/maria/ma_locking.c:
Added usage of MARIA_FILE_OPEN_COUNT_OFFSET
Added _ma_mark_file_crashed()
storage/maria/ma_loghandler.c:
Fixed bug where we logged uninitialized memory
storage/maria/ma_open.c:
Moved state->changed to be at start of state info on disk to allow one to easly mark files as crashed
storage/maria/ma_page.c:
Disable 'dummy' checksumming of pages as this gave false warnings.
(Need to investigate if this is ever needed)
storage/maria/ma_pagecache.c:
Fixed wrong shift that caused Maria to crash on files > 4G
storage/maria/ma_recovery.c:
In case of errors, start writing on new line if we where in %## %## printing mode (Made errors more readable)
Changed global variable name from warnings -> recovery_warnings
Use MARIA_FILE_CREATE_RENAME_LSN_OFFSET instead of constant
Removed special handling of row position for deleted keys. Keys now always includes row positions
_ma_apply_undo_row_delete() now gets page and row position
Added check that we don't loop forever when handling undo's (in case of bug in undo chain)
Print name of failed REDO/UNDO
storage/maria/ma_recovery.h:
Removed old comment
storage/maria/ma_static.c:
Chaned version number of Maria files to not accidently use old ones (becasue of change of ordering of status variables)
storage/maria/ma_test2.c:
Added option -u to specify number of rows to update
Changed old option -u to be -A, as for ma_test1
Fixed bug in update of rows with blobs (before blobs was always reset to empty on update)
First created blob is now of max blob length to ensure we have at least one big blob in the table
storage/maria/ma_test_all.sh:
More tests
storage/maria/ma_test_recovery.expected:
Updated results
storage/maria/ma_test_recovery:
Changed tests to use bigger blobs (not just 1K)
Added new tests that tests recovery of update with blobs
Removed comparision of .MAD file as it's not guranteed that recovery from scratch gives identical data file as original update
(compact_page() may be called at different times during normal execution and during REDO)
storage/maria/ma_update.c:
Simplify code (changed * to if)
storage/maria/maria_chk.c:
Make output more readable
storage/maria/maria_def.h:
Changed 'changed' to int to prepare for more bits
Added 2 more bytes to status information
Added 'st_mara_row->min_length' for storing min length needed on head page

Fixed bug in update of rows with blobs (before blobs was always reset to empty on update)
storage/maria/ma_test_big.sh:
Testing of insert, update, delete, recovery and undo of rows with blobs
Thanks to the random-ness of ma_test2 this is likely to find most bugs in the row handling

Increase the calculated 'head_length' with the number of bytes used for extents.
Update row->space_on_head_page also in _ma_bitmap_find_new_place()
Make _ma_bitmap_get_page_bits() global. (Needed for UNDO handling)
Changed _ma_bitmap_flushable() to take MARIA_HA instead of MARIA_SHARE.
This was needed to be able to mark the handler if we had a 'non_flushable' call pending or not.
Don't use 'non_flushable' marking of bitmap pages for not transactional tables.
Added BLOCKUSED_USE_ORG_BITMAP handling also for tail pages.
Added more DBUG_ASSERT() to find possible errors in other code
Some code simplications by adding new local variables
storage/maria/ma_blockrec.c:
UNDO of rows now puts back all part of the row on their original pages and positions.
Changed UNDO of DELETE and UNDO of UPDATE to contain information about the original length of data on head block and also extent information
This changes a lot of logic as now an insert of a row on a page may happen to any position (and not just to the first or next free)
Use PAGE_COUNT to mark if an extent is the start of of a blob. (Needed for extent_to_bitmap_blocks())
Added check_directory() for checking that directroy entries are correct.
Added checking of row checksums when reading rows (with EXTRA_DEBUG)
Added make_space_for_directory() and extend_directory() for doing expansion of directory
Added get_rowpos_in_head_or_tail_page() to be able to store head/tail on original position in UNDO

Added row->min_length to hold minmum required space needed on head page
Changed find_free_position() to use make_space_for_directory()
Changed make_empty_page() to allow optional creation of directory entry
Changed delete_head_or_tail() and _ma_apply_undo_row_isnert() to not copy pagecache block (speed optimization)
Changed _ma_apply_redo_insert_row_head_or_tail() to be able to insert new row at any position on 'new' page
Changed _ma_apply_undo_row_delete() and _ma_apply_undo_row_update() to put row in it's original position
Ensure allocation of tail blocks are of at least MIN_TAIL_SIZE.
Ensure we store pages in pinned pages even if read failed. (If not we will have pages pinned forever in page cache)
Write original extent information in UNDO entry, not compacted ones (we need position to tails!)
When setting BLOCKUSED_USED, don't clear other bits (we have to preserve BLOCKUSED_USE_ORG_BITMAP)
Fixed som bugs in directory handling
Fixed bug where we wrote wrong lsn to blob pages
Added separate blob_buffer for fixing bug when updating row that had char/varchar that spanned several pages and also had blobs
Ensure we call _ma_bitmap_flushable() also in case of errors
When doing an update, first delete old entries, then search in bitmap for where to put new information
Info->s -> share
Rowid -> rowid

Use MARIA_FILE_CREATE_RENAME_LSN_OFFSET instead of constant
Removed special handling of row position for deleted keys. Keys now always includes row positions
_ma_apply_undo_row_delete() now gets page and row position
Added check that we don't loop forever when handling undo's (in case of bug in undo chain)
Print name of failed REDO/UNDO
storage/maria/ma_recovery.h:

storage/maria/ma_static.c:
Chaned version number of Maria files to not accidently use old ones (becasue of change of ordering of status variables)

Use PAGE_COUNT to mark if an extent is the start of of a blob. (Needed for extent_to_bitmap_blocks())
Added check_directory() for checking that directroy entries are correct.
Added checking of row checksums when reading rows (with EXTRA_DEBUG)
Added make_space_for_directory() and extend_directory() for doing expansion of directory

Changed _ma_apply_undo_row_delete() and _ma_apply_undo_row_update() to put row in it's original position
Ensure allocation of tail blocks are of at least MIN_TAIL_SIZE.
Ensure we store pages in pinned pages even if read failed. (If not we will have pages pinned forever in page cache)
Write original extent information in UNDO entry, not compacted ones (we need position to tails!)
When setting BLOCKUSED_USED, don't clear other bits (we have to preserve BLOCKUSED_USE_ORG_BITMAP)
Fixed som bugs in directory handling
Fixed bug where we wrote wrong lsn to blob pages
Added separate blob_buffer for fixing bug when updating row that had char/varchar that spanned several pages and also had blobs
Ensure we call _ma_bitmap_flushable() also in case of errors
When doing an update, first delete old entries, then search in bitmap for where to put new information
Info->s -> share
Rowid -> rowid
More DBUG_ASSERT()
storage/maria/ma_blockrec.h:
Added START_EXTENT_BIT and TAIL_PAGE_COUNT_MARKER
Added _ma_bitmap_wait_or_flush() and _ma_bitmap_get_page_bits()

Fixed bug where we logged uninitialized memory
storage/maria/ma_open.c:
Moved state->changed to be at start of state info on disk to allow one to easly mark files as crashed
storage/maria/ma_page.c:
Disable 'dummy' checksumming of pages as this gave false warnings.
(Need to investigate if this is ever needed)
storage/maria/ma_pagecache.c:
Fixed wrong shift that caused Maria to crash on files > 4G
storage/maria/ma_recovery.c:
In case of errors, start writing on new line if we where in %## %## printing mode (Made errors more readable)
Changed global variable name from warnings -> recovery_warnings
Use MARIA_FILE_CREATE_RENAME_LSN_OFFSET instead of constant
Removed special handling of row position for deleted keys. Keys now always includes row positions
_ma_apply_undo_row_delete() now gets page and row position
Added check that we don't loop forever when handling undo's (in case of bug in undo chain)
Print name of failed REDO/UNDO
storage/maria/ma_recovery.h:
Removed old comment
storage/maria/ma_static.c:
Chaned version number of Maria files to not accidently use old ones (becasue of change of ordering of status variables)
storage/maria/ma_test2.c:
Added option -u to specify number of rows to update
Changed old option -u to be -A, as for ma_test1
Fixed bug in update of rows with blobs (before blobs was always reset to empty on update)
First created blob is now of max blob length to ensure we have at least one big blob in the table
storage/maria/ma_test_all.sh:
More tests
storage/maria/ma_test_recovery.expected:
Updated results
storage/maria/ma_test_recovery:
Changed tests to use bigger blobs (not just 1K)
Added new tests that tests recovery of update with blobs
Removed comparision of .MAD file as it's not guranteed that recovery from scratch gives identical data file as original update
(compact_page() may be called at different times during normal execution and during REDO)
storage/maria/ma_update.c:
Simplify code (changed * to if)
storage/maria/maria_chk.c:
Make output more readable

Changed old option -u to be -A, as for ma_test1
Fixed bug in update of rows with blobs (before blobs was always reset to empty on update)
First created blob is now of max blob length to ensure we have at least one big blob in the table
storage/maria/ma_test_all.sh:
More tests
storage/maria/ma_test_recovery.expected:
Updated results
storage/maria/ma_test_recovery:
Changed tests to use bigger blobs (not just 1K)
Added new tests that tests recovery of update with blobs
Removed comparision of .MAD file as it's not guranteed that recovery from scratch gives identical data file as original update
(compact_page() may be called at different times during normal execution and during REDO)
storage/maria/ma_update.c:
Simplify code (changed * to if)
storage/maria/maria_chk.c:
Make output more readable
storage/maria/maria_def.h:
Changed 'changed' to int to prepare for more bits
Added 2 more bytes to status information
Added 'st_mara_row->min_length' for storing min length needed on head page
Added 'st_mara_handler->blob_buff & blob_buff_size' for storing blobs
Moved all tunning parameters into one block
Added MARIA_SMALL_BLOB_BUFFER
Added _ma_mark_file_crashed()
storage/myisam/mi_test2.c:
Fixed bug in update of rows with blobs (before blobs was always reset to empty on update)
storage/maria/ma_test_big.sh:
Testing of insert, update, delete, recovery and undo of rows with blobs
Thanks to the random-ness of ma_test2 this is likely to find most bugs in the row handling

WL#3072 - Maria Recovery
Bulk insert: don't log REDO/UNDO for rows, log one UNDO which will
truncate files; this is an optimization and a bugfix (table was left
half-repaired by crash).
Repair: mark table crashed-on-repair at start, bump skip_redo_lsn at start,
this is easier for recovery (tells it to skip old REDOs or even UNDO
phase) and user (tells it to repair) in case of crash, sync files
in the end.
Recovery skips missing or corrupted table and moves to next record
(in REDO or UNDO phase) to be more robust; warns if happens in UNDO phase.
Bugfix for UNDO_KEY_DELETE_WITH_ROOT (tested in ma_test_recovery)
and maria_enable_indexes().
Create missing bitmaps when needed (there can be more than one to create,
in rare cases), log a record for this.
include/myisamchk.h:
new flag: bulk insert repair mustn't bump create_rename_lsn
mysql-test/lib/mtr_report.pl:
skip normal warning in maria-recovery.test
mysql-test/r/maria-recovery.result:
result: crash before bulk insert is committed, causes proper rollback,
and crash right after OPTIMIZE replaces index file with new index file
leads to table marked corrupted and recovery not failing.
mysql-test/t/maria-recovery.test:
- can't check the table or it would commit the transaction,
but check is made after recovery.
- test of crash before bulk-insert-with-repair is committed
(to see if it is rolled back), and of crash after OPTIMIZE has replaced
index file but not finished all operations (to see if recovery fails -
it used to assert when trying to execute an old REDO on the new
index).
storage/maria/CMakeLists.txt:
new file
storage/maria/Makefile.am:
new file
storage/maria/ha_maria.cc:
- If bulk insert on a transactional table using an index repair:
table is initially empty, so don't log REDO/UNDO for data rows
(optimization), just log an UNDO_BULK_INSERT_WITH_REPAIR
which will, if executed, empty the data and index file. Re-enable
logging in end_bulk_insert().
- write log record for repair operation only after it's fully done,
index sort including (maria_repair*() used to write the log record).
- Adding back file->trn=NULL which was removed by mistake earlier.
storage/maria/ha_maria.h:
new member (see ha_maria.cc)
storage/maria/ma_bitmap.c:
Functions to create missing bitmaps:
- one function which creates missing bitmaps in page cache, except
the missing one with max offset which it does not put into page cache
as it will be modified very soon.
- one function which the one above calls, and creates bitmaps in page
cache
- one function to execute REDO_BITMAP_NEW_PAGE which uses the second
one above.
storage/maria/ma_blockrec.c:
- when logging REDO_DELETE_ALL, not only 'records' and 'checksum'
has to be reset under log's mutex.
- execution of REDO_INSERT_ROW_BLOBS now checks the dirty pages' list
- execution of UNDO_BULK_INSERT_WITH_REPAIR
storage/maria/ma_blockrec.h:
new functions
storage/maria/ma_check.c:
- table-flush-before-repair is moved to a separate function reused
by maria_sort_index(); syncing is added
- maria_repair() is allowed to re-enable logging only if it is the one
which disabled it.
- "_ma_flush_table_files_after_repair" was a bad name, it's not after
repair now, and it should not sync as we do more changes to the files
shortly after (sync is postponed to when writing the log record)
- REDO_REPAIR record should be written only after all repair
operations (in particular after sorting index in ha_mara::repair())
- close to the end of repair by sort, flushing of pages must happen
also in the non-quick case, to prepare for the sync at end.
- in parallel repair, some page flushes are not needed as done
by initialize_variables_for_repair().
storage/maria/ma_create.c:
Update skip_redo_lsn, create_rename_lsn optionally.
storage/maria/ma_delete_all.c:
Need to sync files at end of maria_delete_all_rows(), if transactional.
storage/maria/ma_extra.c:
During repair, we sometimes call _ma_flush_table_files() (via
_ma_flush_table_files_before_swap()) while there is a WRITE_CACHE.
storage/maria/ma_key_recover.c:
- when we see CLR_END for UNDO_BULK_INSERT_WITH_REPAIR, re-enable
indices.
- fixing bug: _ma_apply_undo_key_delete() parsed UNDO_KEY_DELETE_WITH_ROOT
wrongly, leading to recovery failure
storage/maria/ma_key_recover.h:
new prototype
storage/maria/ma_locking.c:
DBUG_VOID_RETURN missing
storage/maria/ma_loghandler.c:
UNDO for bulk insert with repair, and REDO for creating bitmaps.
LOGREC_FIRST_FREE to not have to change the for() every time we
add a new record type.
storage/maria/ma_loghandler.h:
new UNDO and REDO
storage/maria/ma_open.c:
Move share.kfile.file=kfile up a bit, so that _ma_update_state_lsns()
can get its value, this fixes a bug where LSN_REPAIRED_BY_MARIA_CHK
was not corrected on disk by maria_open().
Store skip_redo_lsn in index' header.
maria_enable_indexes() had a bug for BLOCK_RECORD, where an empty
file has one page, not 0 bytes.
storage/maria/ma_recovery.c:
- Skip a corrupted, missing, or repaired-with-maria_chk, table in
recovery: don't fail, just go to next REDO or UNDO; but if an UNDO
is skipped in UNDO phase we issue warnings.
- Skip REDO|UNDO in REDO phase if <skip_redo_lsn.
- If UNDO phase fails, delete transactions to not make trnman
assert.
- Update skip_redo_lsn when playing REDO_CREATE_TABLE
- Don't record UNDOs for old transactions which we don't know (long_trid==0)
- Bugfix for UNDO_KEY_DELETE_WITH_ROOT (see ma_key_recover.c)
- Execution of UNDO_BULK_INSERT_WITH_REPAIR
- Don't try to find a page number in REDO_DELETE_ALL
- Pieces moved to ma_recovery_util.c
storage/maria/ma_rename.c:
name change
storage/maria/ma_static.c:
I modified layout of the index' header (inserted skip_redo_lsn in its middle)
storage/maria/ma_test2.c:
allow breaking the test towards the end, tests execution of
UNDO_KEY_DELETE_WITH_ROOT
storage/maria/ma_test_recovery.expected:
6 as testflag instead of 4
storage/maria/ma_test_recovery:
Increase the amount of rollback work to do when testing recovery
with ma_test2; this reproduces the UNDO_KEY_DELETE_WITH_ROOT bug.
storage/maria/maria_chk.c:
skip_redo_lsn should be updated too, for consistency.
Write a REDO_REPAIR after all operations (including sort-records)
have been done.
No reason to flush blocks after maria_chk_data_link() and
maria_sort_records(), there is maria_close() in the end.
write_log_record() is a function, to not clutter maria_chk().
storage/maria/maria_def.h:
New member skip_redo_lsn in the state, and comments
storage/maria/maria_pack.c:
skip_redo_lsn should be updated too, for consistency
storage/maria/ma_recovery_util.c:
_ma_redo_not_needed_for_page(), defined in ma_recovery.c, is needed
by ma_blockrec.c; this causes link issues, resolved by putting
_ma_redo_not_needed_for_page() into a new file (so that it is not
in the same file as repair-related objects of ma_recovery.c).
storage/maria/ma_recovery_util.h:
new file

WL#3071 Maria checkpoint
Ability for flush_pagecache_blocks() to flush only certain pages of
a file, as instructed by an option "filter" pointer-to-function argument;
Checkpoint and background dirty page flushing use that to flush only
pages which have been dirty for long enough and bitmap pages.
Fix for a bug in flush_cached_blocks() (no idea if it could produce
a bug in real life, but theoretically it is).
Testing checkpoint in ma_test_recovery via ma_test1 and ma_test2.
Background checkpoint & dirty pages flush thread is still disabled
by default in ha_maria.
mysql-test/r/maria.result:
result update
storage/maria/ha_maria.cc:
blank after function comment
storage/maria/ma_checkpoint.c:
Using an enum instead of 0/1/2 (applying Sanja's review comments).
The comment about "this is an horizon" can be removed as Sanja
created translog_next_LSN() which parse_checkpoint_record() uses.
Variables in ma_checkpoint_background() cannot be declared in the
for() as their value must not be reset at each iteration!
storage/maria/ma_pagecache.c:
adding to flush_pagecache_blocks() optional arguments 'filter'
(pointer to function) and 'filter_arg'; if filter!=NULL this function
will be called for each block of the file and will reply if this
block and following ones should be flushed or not (3 possible
replies).
Fixing a bug when flush_cached_blocks() skips a pinned page: it has
to unset PCBLOCK_IN_FLUSH set by flush_pagecache_blocks_int().
storage/maria/ma_pagecache.h:
flush_pagecache_blocks() is changed to take "filter" and "filter_arg"
arguments. "filter", if it is not NULL, may return one value
among enum pagecache_flush_filter_result.
storage/maria/ma_recovery.c:
open_count=0 when closing tables at the end of recovery.
storage/maria/ma_test1.c:
Optional checkpoints (-H#) at various stages (stages similar
to --testflag), for testing of checkpoints.
storage/maria/ma_test2.c:
Optional checkpoints (-H#) at various stages (stages similar
to -t), for testing of checkpoints.
storage/maria/ma_test_recovery.expected:
Result update: the results of the additional test run with -H#
(checkpoints) are added here. They are exactly identical to without
checkpoints except that the index's Root (printed by maria_chk)
is more correct when using checkpoints. This is because checkpoint
flushed the state, so it happens to be correct, while no-checkpoint
does not flush the state, and recovery does not recover indexes
so Root is never fixed. When we recover indices, this will go away.
storage/maria/ma_test_recovery:
We duplicate the loop of tests to add an additional run with
checkpoints at various stages, to see if maria_read_log
uses them fine.

WL#3071 Maria checkpoint
Ability for flush_pagecache_blocks() to flush only certain pages of
a file, as instructed by an option "filter" pointer-to-function argument;
Checkpoint and background dirty page flushing use that to flush only
pages which have been dirty for long enough and bitmap pages.
Fix for a bug in flush_cached_blocks() (no idea if it could produce
a bug in real life, but theoretically it is).
Testing checkpoint in ma_test_recovery via ma_test1 and ma_test2.
Background checkpoint & dirty pages flush thread is still disabled
by default in ha_maria.
mysql-test/r/maria.result:
result update
storage/maria/ha_maria.cc:
blank after function comment
storage/maria/ma_checkpoint.c:
Using an enum instead of 0/1/2 (applying Sanja's review comments).
The comment about "this is an horizon" can be removed as Sanja
created translog_next_LSN() which parse_checkpoint_record() uses.
Variables in ma_checkpoint_background() cannot be declared in the
for() as their value must not be reset at each iteration!
storage/maria/ma_pagecache.c:
adding to flush_pagecache_blocks() optional arguments 'filter'
(pointer to function) and 'filter_arg'; if filter!=NULL this function
will be called for each block of the file and will reply if this
block and following ones should be flushed or not (3 possible
replies).
Fixing a bug when flush_cached_blocks() skips a pinned page: it has
to unset PCBLOCK_IN_FLUSH set by flush_pagecache_blocks_int().
storage/maria/ma_pagecache.h:
flush_pagecache_blocks() is changed to take "filter" and "filter_arg"
arguments. "filter", if it is not NULL, may return one value
among enum pagecache_flush_filter_result.
storage/maria/ma_recovery.c:
open_count=0 when closing tables at the end of recovery.
storage/maria/ma_test1.c:
Optional checkpoints (-H#) at various stages (stages similar
to --testflag), for testing of checkpoints.
storage/maria/ma_test2.c:
Optional checkpoints (-H#) at various stages (stages similar
to -t), for testing of checkpoints.
storage/maria/ma_test_recovery.expected:
Result update: the results of the additional test run with -H#
(checkpoints) are added here. They are exactly identical to without
checkpoints except that the index's Root (printed by maria_chk)
is more correct when using checkpoints. This is because checkpoint
flushed the state, so it happens to be correct, while no-checkpoint
does not flush the state, and recovery does not recover indexes
so Root is never fixed. When we recover indices, this will go away.
storage/maria/ma_test_recovery:
We duplicate the loop of tests to add an additional run with
checkpoints at various stages, to see if maria_read_log
uses them fine.

UNDO of rows now puts back all part of the row on their original pages and positions
Added variable _dbug_on_ to speed up execution when DBUG is not going to be used
Added --debug-on option to mysqld (to be able to turn of DBUG with --debug-on=0)
Fixed some bugs with 'non_flushable' marking of bitmap pages
Don't use 'non_flushable' marking of bitmap pages for not transactional tables
SHOW CREATE TABLE now shows if table was created with page checksums
Fixed a lot of bugs with BLOB handling in case of update/REDO and UNDO
More tests (especially for blobs) and DBUG_ASSERTS()
More readable output from maria_read_log and maria_chk
Fixed wrong shift that caused Maria to crash on files > 4G
Mark tables as crashed of REDO fails
dbug/dbug.c:
Changed to use my_bool (allowed me to remove some windows specific code)
Added variable _dbug_on_ to speed up execution when DBUG is not going to be used
Removed initialization of variables if not needed
include/my_dbug.h:
Use my_bool for some functions that was defined as BOOLEAN in dbug.c code
Added DBUGGER_ON/DEBUGGER_OFF to speed up execution when DBUG is not used
include/my_global.h:
Define my_bool early
Increase MY_HOW_OFTEN_TO_WRITE as computers are now faster than 10 years ago
mysql-test/mysql-test-run.pl:
Added debug-on=0 to speed up tests
mysql-test/r/maria-recovery.result:
Added new test by Guilhem to test if UNDO_ROW_DELETE preserves rowid
mysql-test/r/maria.result:
Added testing of page checksums
mysql-test/t/crash_commit_before-master.opt:
Added --debug-on as test require DBUG to work
mysql-test/t/maria-recovery-bitmap-master.opt:
Added --debug-on as test require DBUG to work
mysql-test/t/maria-recovery-master.opt:
Added --debug-on as test require DBUG to work

storage/maria/Makefile.am:
Added ma_test_big.sh
storage/maria/ha_maria.cc:
Store in create_info if page checksums are used (For SHOW CREATE TABLE)
storage/maria/ma_bitmap.c:
Added _ma_bitmap_wait_or_flush() to cause reader of bitmap pages to wait with reading until bitmap is flushed.
Use TAIL_PAGE_COUNT_MARKER for tail pages
Set 'sub_blocks' for and only for the head page or for the first extent of a blob. This is needed for store_extent_info() to be able to set START_EXTENT_BIT's
Don't allocate more than 0x3ffff pages in one extent (We need bit 0x4000 as a START_EXTENT_BIT)
Increase the calculated 'head_length' with the number of bytes used for extents.
Update row->space_on_head_page also in _ma_bitmap_find_new_place()
Make _ma_bitmap_get_page_bits() global. (Needed for UNDO handling)
Changed _ma_bitmap_flushable() to take MARIA_HA instead of MARIA_SHARE.
This was needed to be able to mark the handler if we had a 'non_flushable' call pending or not.
Don't use 'non_flushable' marking of bitmap pages for not transactional tables.
Added BLOCKUSED_USE_ORG_BITMAP handling also for tail pages.
Added more DBUG_ASSERT() to find possible errors in other code
Some code simplications by adding new local variables
storage/maria/ma_blockrec.c:
UNDO of rows now puts back all part of the row on their original pages and positions.
Changed UNDO of DELETE and UNDO of UPDATE to contain information about the original length of data on head block and also extent information
This changes a lot of logic as now an insert of a row on a page may happen to any position (and not just to the first or next free)
Use PAGE_COUNT to mark if an extent is the start of of a blob. (Needed for extent_to_bitmap_blocks())
Added check_directory() for checking that directroy entries are correct.
Added checking of row checksums when reading rows (with EXTRA_DEBUG)
Added make_space_for_directory() and extend_directory() for doing expansion of directory
Added get_rowpos_in_head_or_tail_page() to be able to store head/tail on original position in UNDO
Added extent_to_bitmap_blocks() to be able to generate original bitmap blocks from UNDO entry
Added _ma_update_at_original_place() for UNDO of DELETES
Added row->min_length to hold minmum required space needed on head page
Changed find_free_position() to use make_space_for_directory()
Changed make_empty_page() to allow optional creation of directory entry
Changed delete_head_or_tail() and _ma_apply_undo_row_isnert() to not copy pagecache block (speed optimization)
Changed _ma_apply_redo_insert_row_head_or_tail() to be able to insert new row at any position on 'new' page
Changed _ma_apply_undo_row_delete() and _ma_apply_undo_row_update() to put row in it's original position
Ensure allocation of tail blocks are of at least MIN_TAIL_SIZE.
Ensure we store pages in pinned pages even if read failed. (If not we will have pages pinned forever in page cache)
Write original extent information in UNDO entry, not compacted ones (we need position to tails!)
When setting BLOCKUSED_USED, don't clear other bits (we have to preserve BLOCKUSED_USE_ORG_BITMAP)
Fixed som bugs in directory handling
Fixed bug where we wrote wrong lsn to blob pages
Added separate blob_buffer for fixing bug when updating row that had char/varchar that spanned several pages and also had blobs
Ensure we call _ma_bitmap_flushable() also in case of errors
When doing an update, first delete old entries, then search in bitmap for where to put new information
Info->s -> share
Rowid -> rowid
More DBUG_ASSERT()
storage/maria/ma_blockrec.h:
Added START_EXTENT_BIT and TAIL_PAGE_COUNT_MARKER
Added _ma_bitmap_wait_or_flush() and _ma_bitmap_get_page_bits()
storage/maria/ma_check.c:
Don't write extra empty line if there is no deleted blocks
Ignore START_EXTENT_BIT's in page count
Call _ma_fast_unlock_key_del() to free key_del link
storage/maria/ma_close.c:
Ensure that used_key_del is 0. (If not, someone forgot to call _ma_unlock_key_del())
storage/maria/ma_create.c:
Changed constant to macro
storage/maria/ma_delete.c:
For deleted keys, log also position to row
storage/maria/ma_extra.c:
Release blob buffer at maria_reset() if bigger than MARIA_SMALL_BLOB_BUFFER
storage/maria/ma_key_recover.c:
Added bzero() of LSN that confused paged cache in case of uninitialized block
Mark file crashed if applying of index changes fails
Added calls to _ma_fast_unlock_key_del() for protection of shared key_del link.
storage/maria/ma_locking.c:
Added usage of MARIA_FILE_OPEN_COUNT_OFFSET
Added _ma_mark_file_crashed()
storage/maria/ma_loghandler.c:
Fixed bug where we logged uninitialized memory
storage/maria/ma_open.c:
Moved state->changed to be at start of state info on disk to allow one to easly mark files as crashed
storage/maria/ma_page.c:
Disable 'dummy' checksumming of pages as this gave false warnings.
(Need to investigate if this is ever needed)
storage/maria/ma_pagecache.c:
Fixed wrong shift that caused Maria to crash on files > 4G
storage/maria/ma_recovery.c:
In case of errors, start writing on new line if we where in %## %## printing mode (Made errors more readable)
Changed global variable name from warnings -> recovery_warnings
Use MARIA_FILE_CREATE_RENAME_LSN_OFFSET instead of constant
Removed special handling of row position for deleted keys. Keys now always includes row positions
_ma_apply_undo_row_delete() now gets page and row position
Added check that we don't loop forever when handling undo's (in case of bug in undo chain)
Print name of failed REDO/UNDO
storage/maria/ma_recovery.h:
Removed old comment
storage/maria/ma_static.c:
Chaned version number of Maria files to not accidently use old ones (becasue of change of ordering of status variables)
storage/maria/ma_test2.c:
Added option -u to specify number of rows to update
Changed old option -u to be -A, as for ma_test1
Fixed bug in update of rows with blobs (before blobs was always reset to empty on update)
First created blob is now of max blob length to ensure we have at least one big blob in the table
storage/maria/ma_test_all.sh:
More tests
storage/maria/ma_test_recovery.expected:
Updated results
storage/maria/ma_test_recovery:
Changed tests to use bigger blobs (not just 1K)
Added new tests that tests recovery of update with blobs
Removed comparision of .MAD file as it's not guranteed that recovery from scratch gives identical data file as original update
(compact_page() may be called at different times during normal execution and during REDO)
storage/maria/ma_update.c:
Simplify code (changed * to if)
storage/maria/maria_chk.c:
Make output more readable

Added --debug-on option to mysqld (to be able to turn of DBUG with --debug-on=0)
Fixed some bugs with 'non_flushable' marking of bitmap pages
Don't use 'non_flushable' marking of bitmap pages for not transactional tables
SHOW CREATE TABLE now shows if table was created with page checksums
Fixed a lot of bugs with BLOB handling in case of update/REDO and UNDO
More tests (especially for blobs) and DBUG_ASSERTS()
More readable output from maria_read_log and maria_chk
Fixed wrong shift that caused Maria to crash on files > 4G
Mark tables as crashed of REDO fails

Added _ma_bitmap_wait_or_flush() to cause reader of bitmap pages to wait with reading until bitmap is flushed.
Use TAIL_PAGE_COUNT_MARKER for tail pages
Set 'sub_blocks' for and only for the head page or for the first extent of a blob. This is needed for store_extent_info() to be able to set START_EXTENT_BIT's
Don't allocate more than 0x3ffff pages in one extent (We need bit 0x4000 as a START_EXTENT_BIT)
Increase the calculated 'head_length' with the number of bytes used for extents.

Some code simplications by adding new local variables
storage/maria/ma_blockrec.c:
UNDO of rows now puts back all part of the row on their original pages and positions.
Changed UNDO of DELETE and UNDO of UPDATE to contain information about the original length of data on head block and also extent information
This changes a lot of logic as now an insert of a row on a page may happen to any position (and not just to the first or next free)
Use PAGE_COUNT to mark if an extent is the start of of a blob. (Needed for extent_to_bitmap_blocks())
Added check_directory() for checking that directroy entries are correct.
Added checking of row checksums when reading rows (with EXTRA_DEBUG)
Added make_space_for_directory() and extend_directory() for doing expansion of directory

Changed _ma_apply_undo_row_delete() and _ma_apply_undo_row_update() to put row in it's original position
Ensure allocation of tail blocks are of at least MIN_TAIL_SIZE.
Ensure we store pages in pinned pages even if read failed. (If not we will have pages pinned forever in page cache)
Write original extent information in UNDO entry, not compacted ones (we need position to tails!)
When setting BLOCKUSED_USED, don't clear other bits (we have to preserve BLOCKUSED_USE_ORG_BITMAP)
Fixed som bugs in directory handling
Fixed bug where we wrote wrong lsn to blob pages
Added separate blob_buffer for fixing bug when updating row that had char/varchar that spanned several pages and also had blobs
Ensure we call _ma_bitmap_flushable() also in case of errors
When doing an update, first delete old entries, then search in bitmap for where to put new information
Info->s -> share
Rowid -> rowid
More DBUG_ASSERT()
storage/maria/ma_blockrec.h:
Added START_EXTENT_BIT and TAIL_PAGE_COUNT_MARKER
Added _ma_bitmap_wait_or_flush() and _ma_bitmap_get_page_bits()

storage/maria/ma_locking.c:
Added usage of MARIA_FILE_OPEN_COUNT_OFFSET
Added _ma_mark_file_crashed()
storage/maria/ma_loghandler.c:
Fixed bug where we logged uninitialized memory
storage/maria/ma_open.c:
Moved state->changed to be at start of state info on disk to allow one to easly mark files as crashed
storage/maria/ma_page.c:
Disable 'dummy' checksumming of pages as this gave false warnings.
(Need to investigate if this is ever needed)
storage/maria/ma_pagecache.c:
Fixed wrong shift that caused Maria to crash on files > 4G
storage/maria/ma_recovery.c:
In case of errors, start writing on new line if we where in %## %## printing mode (Made errors more readable)
Changed global variable name from warnings -> recovery_warnings
Use MARIA_FILE_CREATE_RENAME_LSN_OFFSET instead of constant
Removed special handling of row position for deleted keys. Keys now always includes row positions
_ma_apply_undo_row_delete() now gets page and row position
Added check that we don't loop forever when handling undo's (in case of bug in undo chain)
Print name of failed REDO/UNDO
storage/maria/ma_recovery.h:
Removed old comment
storage/maria/ma_static.c:
Chaned version number of Maria files to not accidently use old ones (becasue of change of ordering of status variables)

Added option -u to specify number of rows to update
Changed old option -u to be -A, as for ma_test1

First created blob is now of max blob length to ensure we have at least one big blob in the table
storage/maria/ma_test_all.sh:
More tests
storage/maria/ma_test_recovery.expected:
Updated results
storage/maria/ma_test_recovery:
Changed tests to use bigger blobs (not just 1K)
Added new tests that tests recovery of update with blobs
Removed comparision of .MAD file as it's not guranteed that recovery from scratch gives identical data file as original update

Store in create_info if page checksums are used (For SHOW CREATE TABLE)
storage/maria/ma_bitmap.c:
Added _ma_bitmap_wait_or_flush() to cause reader of bitmap pages to wait with reading until bitmap is flushed.
Use TAIL_PAGE_COUNT_MARKER for tail pages
Set 'sub_blocks' for and only for the head page or for the first extent of a blob. This is needed for store_extent_info() to be able to set START_EXTENT_BIT's
Don't allocate more than 0x3ffff pages in one extent (We need bit 0x4000 as a START_EXTENT_BIT)
Increase the calculated 'head_length' with the number of bytes used for extents.

Use PAGE_COUNT to mark if an extent is the start of of a blob. (Needed for extent_to_bitmap_blocks())
Added check_directory() for checking that directroy entries are correct.
Added checking of row checksums when reading rows (with EXTRA_DEBUG)
Added make_space_for_directory() and extend_directory() for doing expansion of directory

Changed _ma_apply_undo_row_delete() and _ma_apply_undo_row_update() to put row in it's original position
Ensure allocation of tail blocks are of at least MIN_TAIL_SIZE.
Ensure we store pages in pinned pages even if read failed. (If not we will have pages pinned forever in page cache)
Write original extent information in UNDO entry, not compacted ones (we need position to tails!)
When setting BLOCKUSED_USED, don't clear other bits (we have to preserve BLOCKUSED_USE_ORG_BITMAP)
Fixed som bugs in directory handling
Fixed bug where we wrote wrong lsn to blob pages
Added separate blob_buffer for fixing bug when updating row that had char/varchar that spanned several pages and also had blobs
Ensure we call _ma_bitmap_flushable() also in case of errors

Info->s -> share
Rowid -> rowid
More DBUG_ASSERT()

Added row->min_length to hold minmum required space needed on head page
Changed find_free_position() to use make_space_for_directory()
Changed make_empty_page() to allow optional creation of directory entry
Changed delete_head_or_tail() and _ma_apply_undo_row_isnert() to not copy pagecache block (speed optimization)
Changed _ma_apply_redo_insert_row_head_or_tail() to be able to insert new row at any position on 'new' page
Changed _ma_apply_undo_row_delete() and _ma_apply_undo_row_update() to put row in it's original position
Ensure allocation of tail blocks are of at least MIN_TAIL_SIZE.
Ensure we store pages in pinned pages even if read failed. (If not we will have pages pinned forever in page cache)
Write original extent information in UNDO entry, not compacted ones (we need position to tails!)
When setting BLOCKUSED_USED, don't clear other bits (we have to preserve BLOCKUSED_USE_ORG_BITMAP)
Fixed som bugs in directory handling
Fixed bug where we wrote wrong lsn to blob pages
Added separate blob_buffer for fixing bug when updating row that had char/varchar that spanned several pages and also had blobs
Ensure we call _ma_bitmap_flushable() also in case of errors
When doing an update, first delete old entries, then search in bitmap for where to put new information
Info->s -> share
Rowid -> rowid
More DBUG_ASSERT()
storage/maria/ma_blockrec.h:
Added START_EXTENT_BIT and TAIL_PAGE_COUNT_MARKER
Added _ma_bitmap_wait_or_flush() and _ma_bitmap_get_page_bits()
storage/maria/ma_check.c:
Don't write extra empty line if there is no deleted blocks
Ignore START_EXTENT_BIT's in page count
Call _ma_fast_unlock_key_del() to free key_del link
storage/maria/ma_close.c:
Ensure that used_key_del is 0. (If not, someone forgot to call _ma_unlock_key_del())

Added usage of MARIA_FILE_OPEN_COUNT_OFFSET
Added _ma_mark_file_crashed()
storage/maria/ma_loghandler.c:
Fixed bug where we logged uninitialized memory
storage/maria/ma_open.c:
Moved state->changed to be at start of state info on disk to allow one to easly mark files as crashed
storage/maria/ma_page.c:
Disable 'dummy' checksumming of pages as this gave false warnings.
(Need to investigate if this is ever needed)
storage/maria/ma_pagecache.c:
Fixed wrong shift that caused Maria to crash on files > 4G
storage/maria/ma_recovery.c:
In case of errors, start writing on new line if we where in %## %## printing mode (Made errors more readable)
Changed global variable name from warnings -> recovery_warnings
Use MARIA_FILE_CREATE_RENAME_LSN_OFFSET instead of constant
Removed special handling of row position for deleted keys. Keys now always includes row positions

Chaned version number of Maria files to not accidently use old ones (becasue of change of ordering of status variables)
storage/maria/ma_test2.c:
Added option -u to specify number of rows to update
Changed old option -u to be -A, as for ma_test1
Fixed bug in update of rows with blobs (before blobs was always reset to empty on update)
First created blob is now of max blob length to ensure we have at least one big blob in the table

Updated results
storage/maria/ma_test_recovery:
Changed tests to use bigger blobs (not just 1K)

Simplify code (changed * to if)
storage/maria/maria_chk.c:
Make output more readable
storage/maria/maria_def.h:
Changed 'changed' to int to prepare for more bits

Fixed bug in update of rows with blobs (before blobs was always reset to empty on update)
storage/maria/ma_test_big.sh:
Testing of insert, update, delete, recovery and undo of rows with blobs
Thanks to the random-ness of ma_test2 this is likely to find most bugs in the row handling

WL#3072 - Maria Recovery
Bulk insert: don't log REDO/UNDO for rows, log one UNDO which will
truncate files; this is an optimization and a bugfix (table was left
half-repaired by crash).
Repair: mark table crashed-on-repair at start, bump skip_redo_lsn at start,
this is easier for recovery (tells it to skip old REDOs or even UNDO
phase) and user (tells it to repair) in case of crash, sync files
in the end.
Recovery skips missing or corrupted table and moves to next record
(in REDO or UNDO phase) to be more robust; warns if happens in UNDO phase.
Bugfix for UNDO_KEY_DELETE_WITH_ROOT (tested in ma_test_recovery)
and maria_enable_indexes().
Create missing bitmaps when needed (there can be more than one to create,
in rare cases), log a record for this.
include/myisamchk.h:
new flag: bulk insert repair mustn't bump create_rename_lsn
mysql-test/lib/mtr_report.pl:
skip normal warning in maria-recovery.test
mysql-test/r/maria-recovery.result:
result: crash before bulk insert is committed, causes proper rollback,
and crash right after OPTIMIZE replaces index file with new index file
leads to table marked corrupted and recovery not failing.
mysql-test/t/maria-recovery.test:
- can't check the table or it would commit the transaction,
but check is made after recovery.
- test of crash before bulk-insert-with-repair is committed
(to see if it is rolled back), and of crash after OPTIMIZE has replaced
index file but not finished all operations (to see if recovery fails -
it used to assert when trying to execute an old REDO on the new
index).
storage/maria/CMakeLists.txt:
new file
storage/maria/Makefile.am:
new file
storage/maria/ha_maria.cc:
- If bulk insert on a transactional table using an index repair:
table is initially empty, so don't log REDO/UNDO for data rows
(optimization), just log an UNDO_BULK_INSERT_WITH_REPAIR
which will, if executed, empty the data and index file. Re-enable
logging in end_bulk_insert().
- write log record for repair operation only after it's fully done,
index sort including (maria_repair*() used to write the log record).
- Adding back file->trn=NULL which was removed by mistake earlier.
storage/maria/ha_maria.h:
new member (see ha_maria.cc)
storage/maria/ma_bitmap.c:
Functions to create missing bitmaps:
- one function which creates missing bitmaps in page cache, except
the missing one with max offset which it does not put into page cache
as it will be modified very soon.
- one function which the one above calls, and creates bitmaps in page
cache
- one function to execute REDO_BITMAP_NEW_PAGE which uses the second
one above.
storage/maria/ma_blockrec.c:
- when logging REDO_DELETE_ALL, not only 'records' and 'checksum'
has to be reset under log's mutex.
- execution of REDO_INSERT_ROW_BLOBS now checks the dirty pages' list
- execution of UNDO_BULK_INSERT_WITH_REPAIR
storage/maria/ma_blockrec.h:
new functions
storage/maria/ma_check.c:
- table-flush-before-repair is moved to a separate function reused
by maria_sort_index(); syncing is added
- maria_repair() is allowed to re-enable logging only if it is the one
which disabled it.
- "_ma_flush_table_files_after_repair" was a bad name, it's not after
repair now, and it should not sync as we do more changes to the files
shortly after (sync is postponed to when writing the log record)
- REDO_REPAIR record should be written only after all repair
operations (in particular after sorting index in ha_mara::repair())
- close to the end of repair by sort, flushing of pages must happen
also in the non-quick case, to prepare for the sync at end.
- in parallel repair, some page flushes are not needed as done
by initialize_variables_for_repair().
storage/maria/ma_create.c:
Update skip_redo_lsn, create_rename_lsn optionally.
storage/maria/ma_delete_all.c:
Need to sync files at end of maria_delete_all_rows(), if transactional.
storage/maria/ma_extra.c:
During repair, we sometimes call _ma_flush_table_files() (via
_ma_flush_table_files_before_swap()) while there is a WRITE_CACHE.
storage/maria/ma_key_recover.c:
- when we see CLR_END for UNDO_BULK_INSERT_WITH_REPAIR, re-enable
indices.
- fixing bug: _ma_apply_undo_key_delete() parsed UNDO_KEY_DELETE_WITH_ROOT
wrongly, leading to recovery failure
storage/maria/ma_key_recover.h:
new prototype
storage/maria/ma_locking.c:
DBUG_VOID_RETURN missing
storage/maria/ma_loghandler.c:
UNDO for bulk insert with repair, and REDO for creating bitmaps.
LOGREC_FIRST_FREE to not have to change the for() every time we
add a new record type.
storage/maria/ma_loghandler.h:
new UNDO and REDO
storage/maria/ma_open.c:
Move share.kfile.file=kfile up a bit, so that _ma_update_state_lsns()
can get its value, this fixes a bug where LSN_REPAIRED_BY_MARIA_CHK
was not corrected on disk by maria_open().
Store skip_redo_lsn in index' header.
maria_enable_indexes() had a bug for BLOCK_RECORD, where an empty
file has one page, not 0 bytes.
storage/maria/ma_recovery.c:
- Skip a corrupted, missing, or repaired-with-maria_chk, table in
recovery: don't fail, just go to next REDO or UNDO; but if an UNDO
is skipped in UNDO phase we issue warnings.
- Skip REDO|UNDO in REDO phase if <skip_redo_lsn.
- If UNDO phase fails, delete transactions to not make trnman
assert.
- Update skip_redo_lsn when playing REDO_CREATE_TABLE
- Don't record UNDOs for old transactions which we don't know (long_trid==0)
- Bugfix for UNDO_KEY_DELETE_WITH_ROOT (see ma_key_recover.c)
- Execution of UNDO_BULK_INSERT_WITH_REPAIR
- Don't try to find a page number in REDO_DELETE_ALL
- Pieces moved to ma_recovery_util.c
storage/maria/ma_rename.c:
name change
storage/maria/ma_static.c:
I modified layout of the index' header (inserted skip_redo_lsn in its middle)
storage/maria/ma_test2.c:
allow breaking the test towards the end, tests execution of
UNDO_KEY_DELETE_WITH_ROOT
storage/maria/ma_test_recovery.expected:
6 as testflag instead of 4
storage/maria/ma_test_recovery:
Increase the amount of rollback work to do when testing recovery
with ma_test2; this reproduces the UNDO_KEY_DELETE_WITH_ROOT bug.
storage/maria/maria_chk.c:
skip_redo_lsn should be updated too, for consistency.
Write a REDO_REPAIR after all operations (including sort-records)
have been done.
No reason to flush blocks after maria_chk_data_link() and
maria_sort_records(), there is maria_close() in the end.
write_log_record() is a function, to not clutter maria_chk().
storage/maria/maria_def.h:
New member skip_redo_lsn in the state, and comments
storage/maria/maria_pack.c:
skip_redo_lsn should be updated too, for consistency
storage/maria/ma_recovery_util.c:
_ma_redo_not_needed_for_page(), defined in ma_recovery.c, is needed
by ma_blockrec.c; this causes link issues, resolved by putting
_ma_redo_not_needed_for_page() into a new file (so that it is not
in the same file as repair-related objects of ma_recovery.c).
storage/maria/ma_recovery_util.h:
new file

WL#3071 Maria checkpoint
Ability for flush_pagecache_blocks() to flush only certain pages of
a file, as instructed by an option "filter" pointer-to-function argument;
Checkpoint and background dirty page flushing use that to flush only
pages which have been dirty for long enough and bitmap pages.
Fix for a bug in flush_cached_blocks() (no idea if it could produce
a bug in real life, but theoretically it is).
Testing checkpoint in ma_test_recovery via ma_test1 and ma_test2.
Background checkpoint & dirty pages flush thread is still disabled
by default in ha_maria.
mysql-test/r/maria.result:
result update
storage/maria/ha_maria.cc:
blank after function comment
storage/maria/ma_checkpoint.c:
Using an enum instead of 0/1/2 (applying Sanja's review comments).
The comment about "this is an horizon" can be removed as Sanja
created translog_next_LSN() which parse_checkpoint_record() uses.
Variables in ma_checkpoint_background() cannot be declared in the
for() as their value must not be reset at each iteration!
storage/maria/ma_pagecache.c:
adding to flush_pagecache_blocks() optional arguments 'filter'
(pointer to function) and 'filter_arg'; if filter!=NULL this function
will be called for each block of the file and will reply if this
block and following ones should be flushed or not (3 possible
replies).
Fixing a bug when flush_cached_blocks() skips a pinned page: it has
to unset PCBLOCK_IN_FLUSH set by flush_pagecache_blocks_int().
storage/maria/ma_pagecache.h:
flush_pagecache_blocks() is changed to take "filter" and "filter_arg"
arguments. "filter", if it is not NULL, may return one value
among enum pagecache_flush_filter_result.
storage/maria/ma_recovery.c:
open_count=0 when closing tables at the end of recovery.
storage/maria/ma_test1.c:
Optional checkpoints (-H#) at various stages (stages similar
to --testflag), for testing of checkpoints.
storage/maria/ma_test2.c:
Optional checkpoints (-H#) at various stages (stages similar
to -t), for testing of checkpoints.
storage/maria/ma_test_recovery.expected:
Result update: the results of the additional test run with -H#
(checkpoints) are added here. They are exactly identical to without
checkpoints except that the index's Root (printed by maria_chk)
is more correct when using checkpoints. This is because checkpoint
flushed the state, so it happens to be correct, while no-checkpoint
does not flush the state, and recovery does not recover indexes
so Root is never fixed. When we recover indices, this will go away.
storage/maria/ma_test_recovery:
We duplicate the loop of tests to add an additional run with
checkpoints at various stages, to see if maria_read_log
uses them fine.

storage/maria/ma_test_recovery:
We duplicate the loop of tests to add an additional run with
checkpoints at various stages, to see if maria_read_log
uses them fine.

WL#3071 Maria checkpoint
Ability for flush_pagecache_blocks() to flush only certain pages of
a file, as instructed by an option "filter" pointer-to-function argument;
Checkpoint and background dirty page flushing use that to flush only
pages which have been dirty for long enough and bitmap pages.
Fix for a bug in flush_cached_blocks() (no idea if it could produce
a bug in real life, but theoretically it is).
Testing checkpoint in ma_test_recovery via ma_test1 and ma_test2.
Background checkpoint & dirty pages flush thread is still disabled
by default in ha_maria.
mysql-test/r/maria.result:
result update
storage/maria/ha_maria.cc:
blank after function comment
storage/maria/ma_checkpoint.c:
Using an enum instead of 0/1/2 (applying Sanja's review comments).
The comment about "this is an horizon" can be removed as Sanja
created translog_next_LSN() which parse_checkpoint_record() uses.
Variables in ma_checkpoint_background() cannot be declared in the
for() as their value must not be reset at each iteration!
storage/maria/ma_pagecache.c:
adding to flush_pagecache_blocks() optional arguments 'filter'
(pointer to function) and 'filter_arg'; if filter!=NULL this function
will be called for each block of the file and will reply if this
block and following ones should be flushed or not (3 possible
replies).
Fixing a bug when flush_cached_blocks() skips a pinned page: it has
to unset PCBLOCK_IN_FLUSH set by flush_pagecache_blocks_int().
storage/maria/ma_pagecache.h:
flush_pagecache_blocks() is changed to take "filter" and "filter_arg"
arguments. "filter", if it is not NULL, may return one value
among enum pagecache_flush_filter_result.
storage/maria/ma_recovery.c:
open_count=0 when closing tables at the end of recovery.
storage/maria/ma_test1.c:
Optional checkpoints (-H#) at various stages (stages similar
to --testflag), for testing of checkpoints.
storage/maria/ma_test2.c:
Optional checkpoints (-H#) at various stages (stages similar
to -t), for testing of checkpoints.
storage/maria/ma_test_recovery.expected:
Result update: the results of the additional test run with -H#
(checkpoints) are added here. They are exactly identical to without
checkpoints except that the index's Root (printed by maria_chk)
is more correct when using checkpoints. This is because checkpoint
flushed the state, so it happens to be correct, while no-checkpoint
does not flush the state, and recovery does not recover indexes
so Root is never fixed. When we recover indices, this will go away.

UNDO of rows now puts back all part of the row on their original pages and positions
Added variable _dbug_on_ to speed up execution when DBUG is not going to be used
Added --debug-on option to mysqld (to be able to turn of DBUG with --debug-on=0)
Fixed some bugs with 'non_flushable' marking of bitmap pages
Don't use 'non_flushable' marking of bitmap pages for not transactional tables
SHOW CREATE TABLE now shows if table was created with page checksums
Fixed a lot of bugs with BLOB handling in case of update/REDO and UNDO
More tests (especially for blobs) and DBUG_ASSERTS()
More readable output from maria_read_log and maria_chk
Fixed wrong shift that caused Maria to crash on files > 4G
Mark tables as crashed of REDO fails
dbug/dbug.c:
Changed to use my_bool (allowed me to remove some windows specific code)
Added variable _dbug_on_ to speed up execution when DBUG is not going to be used
Removed initialization of variables if not needed
include/my_dbug.h:
Use my_bool for some functions that was defined as BOOLEAN in dbug.c code
Added DBUGGER_ON/DEBUGGER_OFF to speed up execution when DBUG is not used
include/my_global.h:
Define my_bool early
Increase MY_HOW_OFTEN_TO_WRITE as computers are now faster than 10 years ago
mysql-test/mysql-test-run.pl:
Added debug-on=0 to speed up tests
mysql-test/r/maria-recovery.result:
Added new test by Guilhem to test if UNDO_ROW_DELETE preserves rowid
mysql-test/r/maria.result:
Added testing of page checksums

Indentation fixes
Removed end spaces
sql/sql_show.cc:
Allow update_create_info() to inform MySQL if PACK_KEYS, NO_PACK_KEYS, CHECKSUM, PAGE_CHECKSUM or DELAY_KEY_WRITE is used
storage/maria/Makefile.am:
Added ma_test_big.sh
storage/maria/ha_maria.cc:
Store in create_info if page checksums are used (For SHOW CREATE TABLE)
storage/maria/ma_bitmap.c:
Added _ma_bitmap_wait_or_flush() to cause reader of bitmap pages to wait with reading until bitmap is flushed.
Use TAIL_PAGE_COUNT_MARKER for tail pages
Set 'sub_blocks' for and only for the head page or for the first extent of a blob. This is needed for store_extent_info() to be able to set START_EXTENT_BIT's
Don't allocate more than 0x3ffff pages in one extent (We need bit 0x4000 as a START_EXTENT_BIT)
Increase the calculated 'head_length' with the number of bytes used for extents.
Update row->space_on_head_page also in _ma_bitmap_find_new_place()
Make _ma_bitmap_get_page_bits() global. (Needed for UNDO handling)
Changed _ma_bitmap_flushable() to take MARIA_HA instead of MARIA_SHARE.
This was needed to be able to mark the handler if we had a 'non_flushable' call pending or not.
Don't use 'non_flushable' marking of bitmap pages for not transactional tables.
Added BLOCKUSED_USE_ORG_BITMAP handling also for tail pages.
Added more DBUG_ASSERT() to find possible errors in other code
Some code simplications by adding new local variables
storage/maria/ma_blockrec.c:
UNDO of rows now puts back all part of the row on their original pages and positions.
Changed UNDO of DELETE and UNDO of UPDATE to contain information about the original length of data on head block and also extent information
This changes a lot of logic as now an insert of a row on a page may happen to any position (and not just to the first or next free)
Use PAGE_COUNT to mark if an extent is the start of of a blob. (Needed for extent_to_bitmap_blocks())
Added check_directory() for checking that directroy entries are correct.
Added checking of row checksums when reading rows (with EXTRA_DEBUG)
Added make_space_for_directory() and extend_directory() for doing expansion of directory
Added get_rowpos_in_head_or_tail_page() to be able to store head/tail on original position in UNDO
Added extent_to_bitmap_blocks() to be able to generate original bitmap blocks from UNDO entry
Added _ma_update_at_original_place() for UNDO of DELETES
Added row->min_length to hold minmum required space needed on head page
Changed find_free_position() to use make_space_for_directory()
Changed make_empty_page() to allow optional creation of directory entry
Changed delete_head_or_tail() and _ma_apply_undo_row_isnert() to not copy pagecache block (speed optimization)
Changed _ma_apply_redo_insert_row_head_or_tail() to be able to insert new row at any position on 'new' page
Changed _ma_apply_undo_row_delete() and _ma_apply_undo_row_update() to put row in it's original position
Ensure allocation of tail blocks are of at least MIN_TAIL_SIZE.
Ensure we store pages in pinned pages even if read failed. (If not we will have pages pinned forever in page cache)
Write original extent information in UNDO entry, not compacted ones (we need position to tails!)
When setting BLOCKUSED_USED, don't clear other bits (we have to preserve BLOCKUSED_USE_ORG_BITMAP)
Fixed som bugs in directory handling
Fixed bug where we wrote wrong lsn to blob pages
Added separate blob_buffer for fixing bug when updating row that had char/varchar that spanned several pages and also had blobs
Ensure we call _ma_bitmap_flushable() also in case of errors
When doing an update, first delete old entries, then search in bitmap for where to put new information
Info->s -> share
Rowid -> rowid
More DBUG_ASSERT()
storage/maria/ma_blockrec.h:
Added START_EXTENT_BIT and TAIL_PAGE_COUNT_MARKER
Added _ma_bitmap_wait_or_flush() and _ma_bitmap_get_page_bits()
storage/maria/ma_check.c:
Don't write extra empty line if there is no deleted blocks
Ignore START_EXTENT_BIT's in page count
Call _ma_fast_unlock_key_del() to free key_del link
storage/maria/ma_close.c:
Ensure that used_key_del is 0. (If not, someone forgot to call _ma_unlock_key_del())
storage/maria/ma_create.c:
Changed constant to macro
storage/maria/ma_delete.c:
For deleted keys, log also position to row
storage/maria/ma_extra.c:
Release blob buffer at maria_reset() if bigger than MARIA_SMALL_BLOB_BUFFER
storage/maria/ma_key_recover.c:
Added bzero() of LSN that confused paged cache in case of uninitialized block
Mark file crashed if applying of index changes fails
Added calls to _ma_fast_unlock_key_del() for protection of shared key_del link.
storage/maria/ma_locking.c:
Added usage of MARIA_FILE_OPEN_COUNT_OFFSET
Added _ma_mark_file_crashed()
storage/maria/ma_loghandler.c:
Fixed bug where we logged uninitialized memory
storage/maria/ma_open.c:
Moved state->changed to be at start of state info on disk to allow one to easly mark files as crashed
storage/maria/ma_page.c:
Disable 'dummy' checksumming of pages as this gave false warnings.
(Need to investigate if this is ever needed)
storage/maria/ma_pagecache.c:
Fixed wrong shift that caused Maria to crash on files > 4G
storage/maria/ma_recovery.c:
In case of errors, start writing on new line if we where in %## %## printing mode (Made errors more readable)
Changed global variable name from warnings -> recovery_warnings
Use MARIA_FILE_CREATE_RENAME_LSN_OFFSET instead of constant
Removed special handling of row position for deleted keys. Keys now always includes row positions
_ma_apply_undo_row_delete() now gets page and row position
Added check that we don't loop forever when handling undo's (in case of bug in undo chain)
Print name of failed REDO/UNDO
storage/maria/ma_recovery.h:
Removed old comment
storage/maria/ma_static.c:
Chaned version number of Maria files to not accidently use old ones (becasue of change of ordering of status variables)
storage/maria/ma_test2.c:
Added option -u to specify number of rows to update
Changed old option -u to be -A, as for ma_test1
Fixed bug in update of rows with blobs (before blobs was always reset to empty on update)
First created blob is now of max blob length to ensure we have at least one big blob in the table
storage/maria/ma_test_all.sh:
More tests
storage/maria/ma_test_recovery.expected:
Updated results
storage/maria/ma_test_recovery:
Changed tests to use bigger blobs (not just 1K)
Added new tests that tests recovery of update with blobs
Removed comparision of .MAD file as it's not guranteed that recovery from scratch gives identical data file as original update
(compact_page() may be called at different times during normal execution and during REDO)
storage/maria/ma_update.c:
Simplify code (changed * to if)
storage/maria/maria_chk.c:
Make output more readable
storage/maria/maria_def.h:
Changed 'changed' to int to prepare for more bits
Added 2 more bytes to status information
Added 'st_mara_row->min_length' for storing min length needed on head page

Moved all tunning parameters into one block
Added MARIA_SMALL_BLOB_BUFFER
Added _ma_mark_file_crashed()

Fixed bug in update of rows with blobs (before blobs was always reset to empty on update)
storage/maria/ma_test_big.sh:
Testing of insert, update, delete, recovery and undo of rows with blobs
Thanks to the random-ness of ma_test2 this is likely to find most bugs in the row handling

Use TAIL_PAGE_COUNT_MARKER for tail pages
Set 'sub_blocks' for and only for the head page or for the first extent of a blob. This is needed for store_extent_info() to be able to set START_EXTENT_BIT's
Don't allocate more than 0x3ffff pages in one extent (We need bit 0x4000 as a START_EXTENT_BIT)
Increase the calculated 'head_length' with the number of bytes used for extents.

storage/maria/ma_blockrec.c:
UNDO of rows now puts back all part of the row on their original pages and positions.
Changed UNDO of DELETE and UNDO of UPDATE to contain information about the original length of data on head block and also extent information
This changes a lot of logic as now an insert of a row on a page may happen to any position (and not just to the first or next free)
Use PAGE_COUNT to mark if an extent is the start of of a blob. (Needed for extent_to_bitmap_blocks())
Added check_directory() for checking that directroy entries are correct.
Added checking of row checksums when reading rows (with EXTRA_DEBUG)
Added make_space_for_directory() and extend_directory() for doing expansion of directory

Changed _ma_apply_undo_row_delete() and _ma_apply_undo_row_update() to put row in it's original position
Ensure allocation of tail blocks are of at least MIN_TAIL_SIZE.
Ensure we store pages in pinned pages even if read failed. (If not we will have pages pinned forever in page cache)
Write original extent information in UNDO entry, not compacted ones (we need position to tails!)
When setting BLOCKUSED_USED, don't clear other bits (we have to preserve BLOCKUSED_USE_ORG_BITMAP)
Fixed som bugs in directory handling
Fixed bug where we wrote wrong lsn to blob pages
Added separate blob_buffer for fixing bug when updating row that had char/varchar that spanned several pages and also had blobs
Ensure we call _ma_bitmap_flushable() also in case of errors
When doing an update, first delete old entries, then search in bitmap for where to put new information
Info->s -> share
Rowid -> rowid
More DBUG_ASSERT()
storage/maria/ma_blockrec.h:
Added START_EXTENT_BIT and TAIL_PAGE_COUNT_MARKER
Added _ma_bitmap_wait_or_flush() and _ma_bitmap_get_page_bits()

storage/maria/ma_locking.c:
Added usage of MARIA_FILE_OPEN_COUNT_OFFSET
Added _ma_mark_file_crashed()
storage/maria/ma_loghandler.c:
Fixed bug where we logged uninitialized memory
storage/maria/ma_open.c:
Moved state->changed to be at start of state info on disk to allow one to easly mark files as crashed
storage/maria/ma_page.c:
Disable 'dummy' checksumming of pages as this gave false warnings.
(Need to investigate if this is ever needed)
storage/maria/ma_pagecache.c:
Fixed wrong shift that caused Maria to crash on files > 4G
storage/maria/ma_recovery.c:
In case of errors, start writing on new line if we where in %## %## printing mode (Made errors more readable)
Changed global variable name from warnings -> recovery_warnings
Use MARIA_FILE_CREATE_RENAME_LSN_OFFSET instead of constant
Removed special handling of row position for deleted keys. Keys now always includes row positions
_ma_apply_undo_row_delete() now gets page and row position
Added check that we don't loop forever when handling undo's (in case of bug in undo chain)
Print name of failed REDO/UNDO
storage/maria/ma_recovery.h:
Removed old comment
storage/maria/ma_static.c:
Chaned version number of Maria files to not accidently use old ones (becasue of change of ordering of status variables)
storage/maria/ma_test2.c:
Added option -u to specify number of rows to update
Changed old option -u to be -A, as for ma_test1
Fixed bug in update of rows with blobs (before blobs was always reset to empty on update)
First created blob is now of max blob length to ensure we have at least one big blob in the table
storage/maria/ma_test_all.sh:
More tests
storage/maria/ma_test_recovery.expected:
Updated results
storage/maria/ma_test_recovery:
Changed tests to use bigger blobs (not just 1K)
Added new tests that tests recovery of update with blobs
Removed comparision of .MAD file as it's not guranteed that recovery from scratch gives identical data file as original update
(compact_page() may be called at different times during normal execution and during REDO)
storage/maria/ma_update.c:
Simplify code (changed * to if)
storage/maria/maria_chk.c:
Make output more readable
storage/maria/maria_def.h:

Ensure allocation of tail blocks are of at least MIN_TAIL_SIZE.
Ensure we store pages in pinned pages even if read failed. (If not we will have pages pinned forever in page cache)
Write original extent information in UNDO entry, not compacted ones (we need position to tails!)
When setting BLOCKUSED_USED, don't clear other bits (we have to preserve BLOCKUSED_USE_ORG_BITMAP)
Fixed som bugs in directory handling
Fixed bug where we wrote wrong lsn to blob pages
Added separate blob_buffer for fixing bug when updating row that had char/varchar that spanned several pages and also had blobs

WL#3072 - Maria Recovery
Bulk insert: don't log REDO/UNDO for rows, log one UNDO which will
truncate files; this is an optimization and a bugfix (table was left
half-repaired by crash).
Repair: mark table crashed-on-repair at start, bump skip_redo_lsn at start,
this is easier for recovery (tells it to skip old REDOs or even UNDO
phase) and user (tells it to repair) in case of crash, sync files
in the end.
Recovery skips missing or corrupted table and moves to next record
(in REDO or UNDO phase) to be more robust; warns if happens in UNDO phase.
Bugfix for UNDO_KEY_DELETE_WITH_ROOT (tested in ma_test_recovery)
and maria_enable_indexes().
Create missing bitmaps when needed (there can be more than one to create,
in rare cases), log a record for this.
include/myisamchk.h:
new flag: bulk insert repair mustn't bump create_rename_lsn
mysql-test/lib/mtr_report.pl:
skip normal warning in maria-recovery.test
mysql-test/r/maria-recovery.result:
result: crash before bulk insert is committed, causes proper rollback,
and crash right after OPTIMIZE replaces index file with new index file
leads to table marked corrupted and recovery not failing.
mysql-test/t/maria-recovery.test:
- can't check the table or it would commit the transaction,
but check is made after recovery.
- test of crash before bulk-insert-with-repair is committed
(to see if it is rolled back), and of crash after OPTIMIZE has replaced
index file but not finished all operations (to see if recovery fails -
it used to assert when trying to execute an old REDO on the new
index).
storage/maria/CMakeLists.txt:
new file
storage/maria/Makefile.am:
new file
storage/maria/ha_maria.cc:
- If bulk insert on a transactional table using an index repair:
table is initially empty, so don't log REDO/UNDO for data rows
(optimization), just log an UNDO_BULK_INSERT_WITH_REPAIR
which will, if executed, empty the data and index file. Re-enable
logging in end_bulk_insert().
- write log record for repair operation only after it's fully done,
index sort including (maria_repair*() used to write the log record).
- Adding back file->trn=NULL which was removed by mistake earlier.
storage/maria/ha_maria.h:
new member (see ha_maria.cc)
storage/maria/ma_bitmap.c:
Functions to create missing bitmaps:
- one function which creates missing bitmaps in page cache, except
the missing one with max offset which it does not put into page cache
as it will be modified very soon.
- one function which the one above calls, and creates bitmaps in page
cache
- one function to execute REDO_BITMAP_NEW_PAGE which uses the second
one above.
storage/maria/ma_blockrec.c:
- when logging REDO_DELETE_ALL, not only 'records' and 'checksum'
has to be reset under log's mutex.
- execution of REDO_INSERT_ROW_BLOBS now checks the dirty pages' list
- execution of UNDO_BULK_INSERT_WITH_REPAIR
storage/maria/ma_blockrec.h:
new functions
storage/maria/ma_check.c:
- table-flush-before-repair is moved to a separate function reused
by maria_sort_index(); syncing is added
- maria_repair() is allowed to re-enable logging only if it is the one
which disabled it.
- "_ma_flush_table_files_after_repair" was a bad name, it's not after
repair now, and it should not sync as we do more changes to the files
shortly after (sync is postponed to when writing the log record)
- REDO_REPAIR record should be written only after all repair
operations (in particular after sorting index in ha_mara::repair())
- close to the end of repair by sort, flushing of pages must happen
also in the non-quick case, to prepare for the sync at end.
- in parallel repair, some page flushes are not needed as done
by initialize_variables_for_repair().
storage/maria/ma_create.c:
Update skip_redo_lsn, create_rename_lsn optionally.
storage/maria/ma_delete_all.c:
Need to sync files at end of maria_delete_all_rows(), if transactional.
storage/maria/ma_extra.c:
During repair, we sometimes call _ma_flush_table_files() (via
_ma_flush_table_files_before_swap()) while there is a WRITE_CACHE.
storage/maria/ma_key_recover.c:
- when we see CLR_END for UNDO_BULK_INSERT_WITH_REPAIR, re-enable
indices.
- fixing bug: _ma_apply_undo_key_delete() parsed UNDO_KEY_DELETE_WITH_ROOT
wrongly, leading to recovery failure
storage/maria/ma_key_recover.h:
new prototype
storage/maria/ma_locking.c:
DBUG_VOID_RETURN missing
storage/maria/ma_loghandler.c:
UNDO for bulk insert with repair, and REDO for creating bitmaps.
LOGREC_FIRST_FREE to not have to change the for() every time we
add a new record type.
storage/maria/ma_loghandler.h:
new UNDO and REDO
storage/maria/ma_open.c:
Move share.kfile.file=kfile up a bit, so that _ma_update_state_lsns()
can get its value, this fixes a bug where LSN_REPAIRED_BY_MARIA_CHK
was not corrected on disk by maria_open().
Store skip_redo_lsn in index' header.
maria_enable_indexes() had a bug for BLOCK_RECORD, where an empty
file has one page, not 0 bytes.
storage/maria/ma_recovery.c:
- Skip a corrupted, missing, or repaired-with-maria_chk, table in
recovery: don't fail, just go to next REDO or UNDO; but if an UNDO
is skipped in UNDO phase we issue warnings.
- Skip REDO|UNDO in REDO phase if <skip_redo_lsn.
- If UNDO phase fails, delete transactions to not make trnman
assert.
- Update skip_redo_lsn when playing REDO_CREATE_TABLE
- Don't record UNDOs for old transactions which we don't know (long_trid==0)
- Bugfix for UNDO_KEY_DELETE_WITH_ROOT (see ma_key_recover.c)
- Execution of UNDO_BULK_INSERT_WITH_REPAIR
- Don't try to find a page number in REDO_DELETE_ALL
- Pieces moved to ma_recovery_util.c
storage/maria/ma_rename.c:
name change
storage/maria/ma_static.c:
I modified layout of the index' header (inserted skip_redo_lsn in its middle)
storage/maria/ma_test2.c:
allow breaking the test towards the end, tests execution of
UNDO_KEY_DELETE_WITH_ROOT
storage/maria/ma_test_recovery.expected:
6 as testflag instead of 4
storage/maria/ma_test_recovery:
Increase the amount of rollback work to do when testing recovery
with ma_test2; this reproduces the UNDO_KEY_DELETE_WITH_ROOT bug.
storage/maria/maria_chk.c:
skip_redo_lsn should be updated too, for consistency.
Write a REDO_REPAIR after all operations (including sort-records)
have been done.
No reason to flush blocks after maria_chk_data_link() and
maria_sort_records(), there is maria_close() in the end.
write_log_record() is a function, to not clutter maria_chk().
storage/maria/maria_def.h:
New member skip_redo_lsn in the state, and comments
storage/maria/maria_pack.c:
skip_redo_lsn should be updated too, for consistency
storage/maria/ma_recovery_util.c:
_ma_redo_not_needed_for_page(), defined in ma_recovery.c, is needed
by ma_blockrec.c; this causes link issues, resolved by putting
_ma_redo_not_needed_for_page() into a new file (so that it is not
in the same file as repair-related objects of ma_recovery.c).
storage/maria/ma_recovery_util.h:

WL#3071 Maria checkpoint
Ability for flush_pagecache_blocks() to flush only certain pages of
a file, as instructed by an option "filter" pointer-to-function argument;
Checkpoint and background dirty page flushing use that to flush only
pages which have been dirty for long enough and bitmap pages.
Fix for a bug in flush_cached_blocks() (no idea if it could produce
a bug in real life, but theoretically it is).
Testing checkpoint in ma_test_recovery via ma_test1 and ma_test2.
Background checkpoint & dirty pages flush thread is still disabled
by default in ha_maria.
mysql-test/r/maria.result:
result update
storage/maria/ha_maria.cc:
blank after function comment
storage/maria/ma_checkpoint.c:
Using an enum instead of 0/1/2 (applying Sanja's review comments).
The comment about "this is an horizon" can be removed as Sanja
created translog_next_LSN() which parse_checkpoint_record() uses.
Variables in ma_checkpoint_background() cannot be declared in the
for() as their value must not be reset at each iteration!
storage/maria/ma_pagecache.c:
adding to flush_pagecache_blocks() optional arguments 'filter'
(pointer to function) and 'filter_arg'; if filter!=NULL this function
will be called for each block of the file and will reply if this
block and following ones should be flushed or not (3 possible
replies).
Fixing a bug when flush_cached_blocks() skips a pinned page: it has
to unset PCBLOCK_IN_FLUSH set by flush_pagecache_blocks_int().
storage/maria/ma_pagecache.h:
flush_pagecache_blocks() is changed to take "filter" and "filter_arg"
arguments. "filter", if it is not NULL, may return one value
among enum pagecache_flush_filter_result.
storage/maria/ma_recovery.c:
open_count=0 when closing tables at the end of recovery.
storage/maria/ma_test1.c:
Optional checkpoints (-H#) at various stages (stages similar
to --testflag), for testing of checkpoints.
storage/maria/ma_test2.c:
Optional checkpoints (-H#) at various stages (stages similar
to -t), for testing of checkpoints.
storage/maria/ma_test_recovery.expected:
Result update: the results of the additional test run with -H#
(checkpoints) are added here. They are exactly identical to without
checkpoints except that the index's Root (printed by maria_chk)
is more correct when using checkpoints. This is because checkpoint
flushed the state, so it happens to be correct, while no-checkpoint
does not flush the state, and recovery does not recover indexes
so Root is never fixed. When we recover indices, this will go away.
storage/maria/ma_test_recovery:
We duplicate the loop of tests to add an additional run with
checkpoints at various stages, to see if maria_read_log
uses them fine.

UNDO of rows now puts back all part of the row on their original pages and positions
Added variable _dbug_on_ to speed up execution when DBUG is not going to be used
Added --debug-on option to mysqld (to be able to turn of DBUG with --debug-on=0)
Fixed some bugs with 'non_flushable' marking of bitmap pages
Don't use 'non_flushable' marking of bitmap pages for not transactional tables
SHOW CREATE TABLE now shows if table was created with page checksums
Fixed a lot of bugs with BLOB handling in case of update/REDO and UNDO
More tests (especially for blobs) and DBUG_ASSERTS()
More readable output from maria_read_log and maria_chk
Fixed wrong shift that caused Maria to crash on files > 4G
Mark tables as crashed of REDO fails
dbug/dbug.c:
Changed to use my_bool (allowed me to remove some windows specific code)
Added variable _dbug_on_ to speed up execution when DBUG is not going to be used
Removed initialization of variables if not needed
include/my_dbug.h:
Use my_bool for some functions that was defined as BOOLEAN in dbug.c code
Added DBUGGER_ON/DEBUGGER_OFF to speed up execution when DBUG is not used
include/my_global.h:
Define my_bool early
Increase MY_HOW_OFTEN_TO_WRITE as computers are now faster than 10 years ago
mysql-test/mysql-test-run.pl:
Added debug-on=0 to speed up tests
mysql-test/r/maria-recovery.result:
Added new test by Guilhem to test if UNDO_ROW_DELETE preserves rowid

Added --debug-on option (to be able to turn of DBUG with --debug-on=0)
Indentation fixes
Removed end spaces
sql/sql_show.cc:
Allow update_create_info() to inform MySQL if PACK_KEYS, NO_PACK_KEYS, CHECKSUM, PAGE_CHECKSUM or DELAY_KEY_WRITE is used
storage/maria/Makefile.am:
Added ma_test_big.sh
storage/maria/ha_maria.cc:
Store in create_info if page checksums are used (For SHOW CREATE TABLE)
storage/maria/ma_bitmap.c:
Added _ma_bitmap_wait_or_flush() to cause reader of bitmap pages to wait with reading until bitmap is flushed.
Use TAIL_PAGE_COUNT_MARKER for tail pages
Set 'sub_blocks' for and only for the head page or for the first extent of a blob. This is needed for store_extent_info() to be able to set START_EXTENT_BIT's
Don't allocate more than 0x3ffff pages in one extent (We need bit 0x4000 as a START_EXTENT_BIT)
Increase the calculated 'head_length' with the number of bytes used for extents.
Update row->space_on_head_page also in _ma_bitmap_find_new_place()
Make _ma_bitmap_get_page_bits() global. (Needed for UNDO handling)
Changed _ma_bitmap_flushable() to take MARIA_HA instead of MARIA_SHARE.
This was needed to be able to mark the handler if we had a 'non_flushable' call pending or not.
Don't use 'non_flushable' marking of bitmap pages for not transactional tables.
Added BLOCKUSED_USE_ORG_BITMAP handling also for tail pages.
Added more DBUG_ASSERT() to find possible errors in other code
Some code simplications by adding new local variables
storage/maria/ma_blockrec.c:
UNDO of rows now puts back all part of the row on their original pages and positions.
Changed UNDO of DELETE and UNDO of UPDATE to contain information about the original length of data on head block and also extent information
This changes a lot of logic as now an insert of a row on a page may happen to any position (and not just to the first or next free)
Use PAGE_COUNT to mark if an extent is the start of of a blob. (Needed for extent_to_bitmap_blocks())
Added check_directory() for checking that directroy entries are correct.
Added checking of row checksums when reading rows (with EXTRA_DEBUG)
Added make_space_for_directory() and extend_directory() for doing expansion of directory
Added get_rowpos_in_head_or_tail_page() to be able to store head/tail on original position in UNDO
Added extent_to_bitmap_blocks() to be able to generate original bitmap blocks from UNDO entry
Added _ma_update_at_original_place() for UNDO of DELETES
Added row->min_length to hold minmum required space needed on head page
Changed find_free_position() to use make_space_for_directory()
Changed make_empty_page() to allow optional creation of directory entry
Changed delete_head_or_tail() and _ma_apply_undo_row_isnert() to not copy pagecache block (speed optimization)
Changed _ma_apply_redo_insert_row_head_or_tail() to be able to insert new row at any position on 'new' page
Changed _ma_apply_undo_row_delete() and _ma_apply_undo_row_update() to put row in it's original position
Ensure allocation of tail blocks are of at least MIN_TAIL_SIZE.
Ensure we store pages in pinned pages even if read failed. (If not we will have pages pinned forever in page cache)
Write original extent information in UNDO entry, not compacted ones (we need position to tails!)
When setting BLOCKUSED_USED, don't clear other bits (we have to preserve BLOCKUSED_USE_ORG_BITMAP)
Fixed som bugs in directory handling
Fixed bug where we wrote wrong lsn to blob pages
Added separate blob_buffer for fixing bug when updating row that had char/varchar that spanned several pages and also had blobs
Ensure we call _ma_bitmap_flushable() also in case of errors
When doing an update, first delete old entries, then search in bitmap for where to put new information
Info->s -> share
Rowid -> rowid
More DBUG_ASSERT()
storage/maria/ma_blockrec.h:
Added START_EXTENT_BIT and TAIL_PAGE_COUNT_MARKER
Added _ma_bitmap_wait_or_flush() and _ma_bitmap_get_page_bits()
storage/maria/ma_check.c:
Don't write extra empty line if there is no deleted blocks
Ignore START_EXTENT_BIT's in page count

storage/maria/ma_pagecache.c:
Fixed wrong shift that caused Maria to crash on files > 4G
storage/maria/ma_recovery.c:
In case of errors, start writing on new line if we where in %## %## printing mode (Made errors more readable)
Changed global variable name from warnings -> recovery_warnings
Use MARIA_FILE_CREATE_RENAME_LSN_OFFSET instead of constant
Removed special handling of row position for deleted keys. Keys now always includes row positions
_ma_apply_undo_row_delete() now gets page and row position
Added check that we don't loop forever when handling undo's (in case of bug in undo chain)
Print name of failed REDO/UNDO
storage/maria/ma_recovery.h:
Removed old comment
storage/maria/ma_static.c:
Chaned version number of Maria files to not accidently use old ones (becasue of change of ordering of status variables)
storage/maria/ma_test2.c:
Added option -u to specify number of rows to update
Changed old option -u to be -A, as for ma_test1
Fixed bug in update of rows with blobs (before blobs was always reset to empty on update)
First created blob is now of max blob length to ensure we have at least one big blob in the table
storage/maria/ma_test_all.sh:
More tests
storage/maria/ma_test_recovery.expected:
Updated results
storage/maria/ma_test_recovery:
Changed tests to use bigger blobs (not just 1K)
Added new tests that tests recovery of update with blobs
Removed comparision of .MAD file as it's not guranteed that recovery from scratch gives identical data file as original update
(compact_page() may be called at different times during normal execution and during REDO)
storage/maria/ma_update.c:
Simplify code (changed * to if)
storage/maria/maria_chk.c:
Make output more readable

WL#3071 Maria checkpoint
Ability for flush_pagecache_blocks() to flush only certain pages of
a file, as instructed by an option "filter" pointer-to-function argument;
Checkpoint and background dirty page flushing use that to flush only
pages which have been dirty for long enough and bitmap pages.
Fix for a bug in flush_cached_blocks() (no idea if it could produce
a bug in real life, but theoretically it is).
Testing checkpoint in ma_test_recovery via ma_test1 and ma_test2.
Background checkpoint & dirty pages flush thread is still disabled
by default in ha_maria.
mysql-test/r/maria.result:
result update
storage/maria/ha_maria.cc:
blank after function comment
storage/maria/ma_checkpoint.c:
Using an enum instead of 0/1/2 (applying Sanja's review comments).
The comment about "this is an horizon" can be removed as Sanja
created translog_next_LSN() which parse_checkpoint_record() uses.
Variables in ma_checkpoint_background() cannot be declared in the
for() as their value must not be reset at each iteration!
storage/maria/ma_pagecache.c:
adding to flush_pagecache_blocks() optional arguments 'filter'
(pointer to function) and 'filter_arg'; if filter!=NULL this function
will be called for each block of the file and will reply if this
block and following ones should be flushed or not (3 possible
replies).
Fixing a bug when flush_cached_blocks() skips a pinned page: it has
to unset PCBLOCK_IN_FLUSH set by flush_pagecache_blocks_int().
storage/maria/ma_pagecache.h:
flush_pagecache_blocks() is changed to take "filter" and "filter_arg"
arguments. "filter", if it is not NULL, may return one value
among enum pagecache_flush_filter_result.
storage/maria/ma_recovery.c:
open_count=0 when closing tables at the end of recovery.
storage/maria/ma_test1.c:
Optional checkpoints (-H#) at various stages (stages similar
to --testflag), for testing of checkpoints.
storage/maria/ma_test2.c:
Optional checkpoints (-H#) at various stages (stages similar
to -t), for testing of checkpoints.
storage/maria/ma_test_recovery.expected:
Result update: the results of the additional test run with -H#
(checkpoints) are added here. They are exactly identical to without
checkpoints except that the index's Root (printed by maria_chk)
is more correct when using checkpoints. This is because checkpoint
flushed the state, so it happens to be correct, while no-checkpoint
does not flush the state, and recovery does not recover indexes
so Root is never fixed. When we recover indices, this will go away.
storage/maria/ma_test_recovery:
We duplicate the loop of tests to add an additional run with
checkpoints at various stages, to see if maria_read_log
uses them fine.

flushed the state, so it happens to be correct, while no-checkpoint
does not flush the state, and recovery does not recover indexes
so Root is never fixed. When we recover indices, this will go away.
storage/maria/ma_test_recovery:
We duplicate the loop of tests to add an additional run with
checkpoints at various stages, to see if maria_read_log
uses them fine.

WL#3071 Maria checkpoint
Ability for flush_pagecache_blocks() to flush only certain pages of
a file, as instructed by an option "filter" pointer-to-function argument;
Checkpoint and background dirty page flushing use that to flush only
pages which have been dirty for long enough and bitmap pages.
Fix for a bug in flush_cached_blocks() (no idea if it could produce
a bug in real life, but theoretically it is).
Testing checkpoint in ma_test_recovery via ma_test1 and ma_test2.
Background checkpoint & dirty pages flush thread is still disabled
by default in ha_maria.
mysql-test/r/maria.result:
result update
storage/maria/ha_maria.cc:
blank after function comment
storage/maria/ma_checkpoint.c:
Using an enum instead of 0/1/2 (applying Sanja's review comments).
The comment about "this is an horizon" can be removed as Sanja
created translog_next_LSN() which parse_checkpoint_record() uses.
Variables in ma_checkpoint_background() cannot be declared in the
for() as their value must not be reset at each iteration!
storage/maria/ma_pagecache.c:
adding to flush_pagecache_blocks() optional arguments 'filter'
(pointer to function) and 'filter_arg'; if filter!=NULL this function
will be called for each block of the file and will reply if this
block and following ones should be flushed or not (3 possible
replies).
Fixing a bug when flush_cached_blocks() skips a pinned page: it has
to unset PCBLOCK_IN_FLUSH set by flush_pagecache_blocks_int().
storage/maria/ma_pagecache.h:
flush_pagecache_blocks() is changed to take "filter" and "filter_arg"
arguments. "filter", if it is not NULL, may return one value
among enum pagecache_flush_filter_result.
storage/maria/ma_recovery.c:
open_count=0 when closing tables at the end of recovery.
storage/maria/ma_test1.c:
Optional checkpoints (-H#) at various stages (stages similar
to --testflag), for testing of checkpoints.
storage/maria/ma_test2.c:
Optional checkpoints (-H#) at various stages (stages similar
to -t), for testing of checkpoints.
storage/maria/ma_test_recovery.expected:

(checkpoints) are added here. They are exactly identical to without
checkpoints except that the index's Root (printed by maria_chk)
is more correct when using checkpoints. This is because checkpoint
flushed the state, so it happens to be correct, while no-checkpoint

UNDO of rows now puts back all part of the row on their original pages and positions
Added variable _dbug_on_ to speed up execution when DBUG is not going to be used
Added --debug-on option to mysqld (to be able to turn of DBUG with --debug-on=0)
Fixed some bugs with 'non_flushable' marking of bitmap pages
Don't use 'non_flushable' marking of bitmap pages for not transactional tables
SHOW CREATE TABLE now shows if table was created with page checksums
Fixed a lot of bugs with BLOB handling in case of update/REDO and UNDO
More tests (especially for blobs) and DBUG_ASSERTS()
More readable output from maria_read_log and maria_chk
Fixed wrong shift that caused Maria to crash on files > 4G
Mark tables as crashed of REDO fails
dbug/dbug.c:
Changed to use my_bool (allowed me to remove some windows specific code)
Added variable _dbug_on_ to speed up execution when DBUG is not going to be used
Removed initialization of variables if not needed
include/my_dbug.h:
Use my_bool for some functions that was defined as BOOLEAN in dbug.c code
Added DBUGGER_ON/DEBUGGER_OFF to speed up execution when DBUG is not used
include/my_global.h:
Define my_bool early
Increase MY_HOW_OFTEN_TO_WRITE as computers are now faster than 10 years ago
mysql-test/mysql-test-run.pl:
Added debug-on=0 to speed up tests
mysql-test/r/maria-recovery.result:

Indentation fixes
Removed end spaces
sql/sql_show.cc:
Allow update_create_info() to inform MySQL if PACK_KEYS, NO_PACK_KEYS, CHECKSUM, PAGE_CHECKSUM or DELAY_KEY_WRITE is used
storage/maria/Makefile.am:
Added ma_test_big.sh
storage/maria/ha_maria.cc:
Store in create_info if page checksums are used (For SHOW CREATE TABLE)
storage/maria/ma_bitmap.c:
Added _ma_bitmap_wait_or_flush() to cause reader of bitmap pages to wait with reading until bitmap is flushed.
Use TAIL_PAGE_COUNT_MARKER for tail pages
Set 'sub_blocks' for and only for the head page or for the first extent of a blob. This is needed for store_extent_info() to be able to set START_EXTENT_BIT's
Don't allocate more than 0x3ffff pages in one extent (We need bit 0x4000 as a START_EXTENT_BIT)
Increase the calculated 'head_length' with the number of bytes used for extents.
Update row->space_on_head_page also in _ma_bitmap_find_new_place()
Make _ma_bitmap_get_page_bits() global. (Needed for UNDO handling)
Changed _ma_bitmap_flushable() to take MARIA_HA instead of MARIA_SHARE.
This was needed to be able to mark the handler if we had a 'non_flushable' call pending or not.
Don't use 'non_flushable' marking of bitmap pages for not transactional tables.
Added BLOCKUSED_USE_ORG_BITMAP handling also for tail pages.
Added more DBUG_ASSERT() to find possible errors in other code
Some code simplications by adding new local variables
storage/maria/ma_blockrec.c:
UNDO of rows now puts back all part of the row on their original pages and positions.
Changed UNDO of DELETE and UNDO of UPDATE to contain information about the original length of data on head block and also extent information
This changes a lot of logic as now an insert of a row on a page may happen to any position (and not just to the first or next free)
Use PAGE_COUNT to mark if an extent is the start of of a blob. (Needed for extent_to_bitmap_blocks())
Added check_directory() for checking that directroy entries are correct.
Added checking of row checksums when reading rows (with EXTRA_DEBUG)
Added make_space_for_directory() and extend_directory() for doing expansion of directory

Changed find_free_position() to use make_space_for_directory()
Changed make_empty_page() to allow optional creation of directory entry
Changed delete_head_or_tail() and _ma_apply_undo_row_isnert() to not copy pagecache block (speed optimization)
Changed _ma_apply_redo_insert_row_head_or_tail() to be able to insert new row at any position on 'new' page
Changed _ma_apply_undo_row_delete() and _ma_apply_undo_row_update() to put row in it's original position
Ensure allocation of tail blocks are of at least MIN_TAIL_SIZE.
Ensure we store pages in pinned pages even if read failed. (If not we will have pages pinned forever in page cache)
Write original extent information in UNDO entry, not compacted ones (we need position to tails!)
When setting BLOCKUSED_USED, don't clear other bits (we have to preserve BLOCKUSED_USE_ORG_BITMAP)
Fixed som bugs in directory handling
Fixed bug where we wrote wrong lsn to blob pages
Added separate blob_buffer for fixing bug when updating row that had char/varchar that spanned several pages and also had blobs
Ensure we call _ma_bitmap_flushable() also in case of errors
When doing an update, first delete old entries, then search in bitmap for where to put new information
Info->s -> share
Rowid -> rowid
More DBUG_ASSERT()
storage/maria/ma_blockrec.h:
Added START_EXTENT_BIT and TAIL_PAGE_COUNT_MARKER
Added _ma_bitmap_wait_or_flush() and _ma_bitmap_get_page_bits()
storage/maria/ma_check.c:
Don't write extra empty line if there is no deleted blocks
Ignore START_EXTENT_BIT's in page count
Call _ma_fast_unlock_key_del() to free key_del link

For deleted keys, log also position to row
storage/maria/ma_extra.c:
Release blob buffer at maria_reset() if bigger than MARIA_SMALL_BLOB_BUFFER
storage/maria/ma_key_recover.c:
Added bzero() of LSN that confused paged cache in case of uninitialized block
Mark file crashed if applying of index changes fails
Added calls to _ma_fast_unlock_key_del() for protection of shared key_del link.
storage/maria/ma_locking.c:
Added usage of MARIA_FILE_OPEN_COUNT_OFFSET
Added _ma_mark_file_crashed()
storage/maria/ma_loghandler.c:
Fixed bug where we logged uninitialized memory
storage/maria/ma_open.c:
Moved state->changed to be at start of state info on disk to allow one to easly mark files as crashed
storage/maria/ma_page.c:
Disable 'dummy' checksumming of pages as this gave false warnings.
(Need to investigate if this is ever needed)
storage/maria/ma_pagecache.c:
Fixed wrong shift that caused Maria to crash on files > 4G
storage/maria/ma_recovery.c:
In case of errors, start writing on new line if we where in %## %## printing mode (Made errors more readable)
Changed global variable name from warnings -> recovery_warnings
Use MARIA_FILE_CREATE_RENAME_LSN_OFFSET instead of constant
Removed special handling of row position for deleted keys. Keys now always includes row positions
_ma_apply_undo_row_delete() now gets page and row position
Added check that we don't loop forever when handling undo's (in case of bug in undo chain)
Print name of failed REDO/UNDO
storage/maria/ma_recovery.h:
Removed old comment
storage/maria/ma_static.c:
Chaned version number of Maria files to not accidently use old ones (becasue of change of ordering of status variables)
storage/maria/ma_test2.c:
Added option -u to specify number of rows to update
Changed old option -u to be -A, as for ma_test1
Fixed bug in update of rows with blobs (before blobs was always reset to empty on update)
First created blob is now of max blob length to ensure we have at least one big blob in the table
storage/maria/ma_test_all.sh:
More tests
storage/maria/ma_test_recovery.expected:
Updated results
storage/maria/ma_test_recovery:
Changed tests to use bigger blobs (not just 1K)
Added new tests that tests recovery of update with blobs
Removed comparision of .MAD file as it's not guranteed that recovery from scratch gives identical data file as original update
(compact_page() may be called at different times during normal execution and during REDO)
storage/maria/ma_update.c:
Simplify code (changed * to if)
storage/maria/maria_chk.c:
Make output more readable
storage/maria/maria_def.h:

Fixed bug in update of rows with blobs (before blobs was always reset to empty on update)
storage/maria/ma_test_big.sh:
Testing of insert, update, delete, recovery and undo of rows with blobs
Thanks to the random-ness of ma_test2 this is likely to find most bugs in the row handling

a file, as instructed by an option "filter" pointer-to-function argument;
Checkpoint and background dirty page flushing use that to flush only
pages which have been dirty for long enough and bitmap pages.
Fix for a bug in flush_cached_blocks() (no idea if it could produce
a bug in real life, but theoretically it is).
Testing checkpoint in ma_test_recovery via ma_test1 and ma_test2.
Background checkpoint & dirty pages flush thread is still disabled
by default in ha_maria.
mysql-test/r/maria.result:
result update
storage/maria/ha_maria.cc:
blank after function comment
storage/maria/ma_checkpoint.c:
Using an enum instead of 0/1/2 (applying Sanja's review comments).
The comment about "this is an horizon" can be removed as Sanja
created translog_next_LSN() which parse_checkpoint_record() uses.
Variables in ma_checkpoint_background() cannot be declared in the
for() as their value must not be reset at each iteration!
storage/maria/ma_pagecache.c:
adding to flush_pagecache_blocks() optional arguments 'filter'
(pointer to function) and 'filter_arg'; if filter!=NULL this function
will be called for each block of the file and will reply if this
block and following ones should be flushed or not (3 possible
replies).
Fixing a bug when flush_cached_blocks() skips a pinned page: it has
to unset PCBLOCK_IN_FLUSH set by flush_pagecache_blocks_int().
storage/maria/ma_pagecache.h:
flush_pagecache_blocks() is changed to take "filter" and "filter_arg"
arguments. "filter", if it is not NULL, may return one value
among enum pagecache_flush_filter_result.

storage/maria/ma_test1.c:
Optional checkpoints (-H#) at various stages (stages similar

storage/maria/ma_test2.c:
Optional checkpoints (-H#) at various stages (stages similar

storage/maria/ma_test_recovery.expected:
Result update: the results of the additional test run with -H#
(checkpoints) are added here. They are exactly identical to without
checkpoints except that the index's Root (printed by maria_chk)
is more correct when using checkpoints. This is because checkpoint
flushed the state, so it happens to be correct, while no-checkpoint
does not flush the state, and recovery does not recover indexes
so Root is never fixed. When we recover indices, this will go away.
storage/maria/ma_test_recovery:
We duplicate the loop of tests to add an additional run with
checkpoints at various stages, to see if maria_read_log
uses them fine.

UNDO of rows now puts back all part of the row on their original pages and positions
Added variable _dbug_on_ to speed up execution when DBUG is not going to be used
Added --debug-on option to mysqld (to be able to turn of DBUG with --debug-on=0)
Fixed some bugs with 'non_flushable' marking of bitmap pages
Don't use 'non_flushable' marking of bitmap pages for not transactional tables
SHOW CREATE TABLE now shows if table was created with page checksums
Fixed a lot of bugs with BLOB handling in case of update/REDO and UNDO
More tests (especially for blobs) and DBUG_ASSERTS()
More readable output from maria_read_log and maria_chk
Fixed wrong shift that caused Maria to crash on files > 4G
Mark tables as crashed of REDO fails
dbug/dbug.c:
Changed to use my_bool (allowed me to remove some windows specific code)
Added variable _dbug_on_ to speed up execution when DBUG is not going to be used
Removed initialization of variables if not needed
include/my_dbug.h:
Use my_bool for some functions that was defined as BOOLEAN in dbug.c code
Added DBUGGER_ON/DEBUGGER_OFF to speed up execution when DBUG is not used
include/my_global.h:
Define my_bool early
Increase MY_HOW_OFTEN_TO_WRITE as computers are now faster than 10 years ago
mysql-test/mysql-test-run.pl:
Added debug-on=0 to speed up tests
mysql-test/r/maria-recovery.result:
Added new test by Guilhem to test if UNDO_ROW_DELETE preserves rowid
mysql-test/r/maria.result:

Indentation fixes
Removed end spaces
sql/sql_show.cc:
Allow update_create_info() to inform MySQL if PACK_KEYS, NO_PACK_KEYS, CHECKSUM, PAGE_CHECKSUM or DELAY_KEY_WRITE is used
storage/maria/Makefile.am:
Added ma_test_big.sh
storage/maria/ha_maria.cc:
Store in create_info if page checksums are used (For SHOW CREATE TABLE)
storage/maria/ma_bitmap.c:
Added _ma_bitmap_wait_or_flush() to cause reader of bitmap pages to wait with reading until bitmap is flushed.
Use TAIL_PAGE_COUNT_MARKER for tail pages
Set 'sub_blocks' for and only for the head page or for the first extent of a blob. This is needed for store_extent_info() to be able to set START_EXTENT_BIT's
Don't allocate more than 0x3ffff pages in one extent (We need bit 0x4000 as a START_EXTENT_BIT)
Increase the calculated 'head_length' with the number of bytes used for extents.
Update row->space_on_head_page also in _ma_bitmap_find_new_place()
Make _ma_bitmap_get_page_bits() global. (Needed for UNDO handling)
Changed _ma_bitmap_flushable() to take MARIA_HA instead of MARIA_SHARE.
This was needed to be able to mark the handler if we had a 'non_flushable' call pending or not.
Don't use 'non_flushable' marking of bitmap pages for not transactional tables.
Added BLOCKUSED_USE_ORG_BITMAP handling also for tail pages.
Added more DBUG_ASSERT() to find possible errors in other code
Some code simplications by adding new local variables
storage/maria/ma_blockrec.c:
UNDO of rows now puts back all part of the row on their original pages and positions.
Changed UNDO of DELETE and UNDO of UPDATE to contain information about the original length of data on head block and also extent information
This changes a lot of logic as now an insert of a row on a page may happen to any position (and not just to the first or next free)
Use PAGE_COUNT to mark if an extent is the start of of a blob. (Needed for extent_to_bitmap_blocks())
Added check_directory() for checking that directroy entries are correct.
Added checking of row checksums when reading rows (with EXTRA_DEBUG)
Added make_space_for_directory() and extend_directory() for doing expansion of directory
Added get_rowpos_in_head_or_tail_page() to be able to store head/tail on original position in UNDO
Added extent_to_bitmap_blocks() to be able to generate original bitmap blocks from UNDO entry
Added _ma_update_at_original_place() for UNDO of DELETES
Added row->min_length to hold minmum required space needed on head page
Changed find_free_position() to use make_space_for_directory()
Changed make_empty_page() to allow optional creation of directory entry
Changed delete_head_or_tail() and _ma_apply_undo_row_isnert() to not copy pagecache block (speed optimization)
Changed _ma_apply_redo_insert_row_head_or_tail() to be able to insert new row at any position on 'new' page
Changed _ma_apply_undo_row_delete() and _ma_apply_undo_row_update() to put row in it's original position
Ensure allocation of tail blocks are of at least MIN_TAIL_SIZE.
Ensure we store pages in pinned pages even if read failed. (If not we will have pages pinned forever in page cache)
Write original extent information in UNDO entry, not compacted ones (we need position to tails!)
When setting BLOCKUSED_USED, don't clear other bits (we have to preserve BLOCKUSED_USE_ORG_BITMAP)
Fixed som bugs in directory handling
Fixed bug where we wrote wrong lsn to blob pages
Added separate blob_buffer for fixing bug when updating row that had char/varchar that spanned several pages and also had blobs
Ensure we call _ma_bitmap_flushable() also in case of errors
When doing an update, first delete old entries, then search in bitmap for where to put new information
Info->s -> share
Rowid -> rowid
More DBUG_ASSERT()
storage/maria/ma_blockrec.h:
Added START_EXTENT_BIT and TAIL_PAGE_COUNT_MARKER
Added _ma_bitmap_wait_or_flush() and _ma_bitmap_get_page_bits()
storage/maria/ma_check.c:
Don't write extra empty line if there is no deleted blocks
Ignore START_EXTENT_BIT's in page count
Call _ma_fast_unlock_key_del() to free key_del link
storage/maria/ma_close.c:
Ensure that used_key_del is 0. (If not, someone forgot to call _ma_unlock_key_del())
storage/maria/ma_create.c:
Changed constant to macro
storage/maria/ma_delete.c:
For deleted keys, log also position to row
storage/maria/ma_extra.c:
Release blob buffer at maria_reset() if bigger than MARIA_SMALL_BLOB_BUFFER
storage/maria/ma_key_recover.c:
Added bzero() of LSN that confused paged cache in case of uninitialized block
Mark file crashed if applying of index changes fails
Added calls to _ma_fast_unlock_key_del() for protection of shared key_del link.
storage/maria/ma_locking.c:
Added usage of MARIA_FILE_OPEN_COUNT_OFFSET
Added _ma_mark_file_crashed()
storage/maria/ma_loghandler.c:
Fixed bug where we logged uninitialized memory
storage/maria/ma_open.c:
Moved state->changed to be at start of state info on disk to allow one to easly mark files as crashed
storage/maria/ma_page.c:
Disable 'dummy' checksumming of pages as this gave false warnings.
(Need to investigate if this is ever needed)
storage/maria/ma_pagecache.c:
Fixed wrong shift that caused Maria to crash on files > 4G
storage/maria/ma_recovery.c:
In case of errors, start writing on new line if we where in %## %## printing mode (Made errors more readable)
Changed global variable name from warnings -> recovery_warnings
Use MARIA_FILE_CREATE_RENAME_LSN_OFFSET instead of constant
Removed special handling of row position for deleted keys. Keys now always includes row positions
_ma_apply_undo_row_delete() now gets page and row position
Added check that we don't loop forever when handling undo's (in case of bug in undo chain)
Print name of failed REDO/UNDO
storage/maria/ma_recovery.h:
Removed old comment
storage/maria/ma_static.c:
Chaned version number of Maria files to not accidently use old ones (becasue of change of ordering of status variables)
storage/maria/ma_test2.c:
Added option -u to specify number of rows to update
Changed old option -u to be -A, as for ma_test1
Fixed bug in update of rows with blobs (before blobs was always reset to empty on update)
First created blob is now of max blob length to ensure we have at least one big blob in the table
storage/maria/ma_test_all.sh:
More tests
storage/maria/ma_test_recovery.expected:
Updated results
storage/maria/ma_test_recovery:
Changed tests to use bigger blobs (not just 1K)
Added new tests that tests recovery of update with blobs
Removed comparision of .MAD file as it's not guranteed that recovery from scratch gives identical data file as original update
(compact_page() may be called at different times during normal execution and during REDO)
storage/maria/ma_update.c:
Simplify code (changed * to if)
storage/maria/maria_chk.c:
Make output more readable
storage/maria/maria_def.h:
Changed 'changed' to int to prepare for more bits
Added 2 more bytes to status information
Added 'st_mara_row->min_length' for storing min length needed on head page
Added 'st_mara_handler->blob_buff & blob_buff_size' for storing blobs
Moved all tunning parameters into one block
Added MARIA_SMALL_BLOB_BUFFER
Added _ma_mark_file_crashed()
storage/myisam/mi_test2.c:
Fixed bug in update of rows with blobs (before blobs was always reset to empty on update)
storage/maria/ma_test_big.sh:
Testing of insert, update, delete, recovery and undo of rows with blobs
Thanks to the random-ness of ma_test2 this is likely to find most bugs in the row handling

WL#3072 - Maria Recovery
Bulk insert: don't log REDO/UNDO for rows, log one UNDO which will
truncate files; this is an optimization and a bugfix (table was left
half-repaired by crash).
Repair: mark table crashed-on-repair at start, bump skip_redo_lsn at start,
this is easier for recovery (tells it to skip old REDOs or even UNDO
phase) and user (tells it to repair) in case of crash, sync files
in the end.
Recovery skips missing or corrupted table and moves to next record
(in REDO or UNDO phase) to be more robust; warns if happens in UNDO phase.
Bugfix for UNDO_KEY_DELETE_WITH_ROOT (tested in ma_test_recovery)
and maria_enable_indexes().
Create missing bitmaps when needed (there can be more than one to create,
in rare cases), log a record for this.
include/myisamchk.h:
new flag: bulk insert repair mustn't bump create_rename_lsn
mysql-test/lib/mtr_report.pl:
skip normal warning in maria-recovery.test
mysql-test/r/maria-recovery.result:
result: crash before bulk insert is committed, causes proper rollback,
and crash right after OPTIMIZE replaces index file with new index file
leads to table marked corrupted and recovery not failing.
mysql-test/t/maria-recovery.test:
- can't check the table or it would commit the transaction,
but check is made after recovery.
- test of crash before bulk-insert-with-repair is committed
(to see if it is rolled back), and of crash after OPTIMIZE has replaced
index file but not finished all operations (to see if recovery fails -
it used to assert when trying to execute an old REDO on the new
index).
storage/maria/CMakeLists.txt:
new file
storage/maria/Makefile.am:
new file
storage/maria/ha_maria.cc:
- If bulk insert on a transactional table using an index repair:
table is initially empty, so don't log REDO/UNDO for data rows
(optimization), just log an UNDO_BULK_INSERT_WITH_REPAIR
which will, if executed, empty the data and index file. Re-enable
logging in end_bulk_insert().
- write log record for repair operation only after it's fully done,
index sort including (maria_repair*() used to write the log record).
- Adding back file->trn=NULL which was removed by mistake earlier.
storage/maria/ha_maria.h:
new member (see ha_maria.cc)
storage/maria/ma_bitmap.c:
Functions to create missing bitmaps:
- one function which creates missing bitmaps in page cache, except
the missing one with max offset which it does not put into page cache
as it will be modified very soon.
- one function which the one above calls, and creates bitmaps in page
cache
- one function to execute REDO_BITMAP_NEW_PAGE which uses the second
one above.
storage/maria/ma_blockrec.c:
- when logging REDO_DELETE_ALL, not only 'records' and 'checksum'
has to be reset under log's mutex.
- execution of REDO_INSERT_ROW_BLOBS now checks the dirty pages' list
- execution of UNDO_BULK_INSERT_WITH_REPAIR
storage/maria/ma_blockrec.h:
new functions
storage/maria/ma_check.c:
- table-flush-before-repair is moved to a separate function reused
by maria_sort_index(); syncing is added
- maria_repair() is allowed to re-enable logging only if it is the one
which disabled it.
- "_ma_flush_table_files_after_repair" was a bad name, it's not after
repair now, and it should not sync as we do more changes to the files
shortly after (sync is postponed to when writing the log record)
- REDO_REPAIR record should be written only after all repair
operations (in particular after sorting index in ha_mara::repair())
- close to the end of repair by sort, flushing of pages must happen
also in the non-quick case, to prepare for the sync at end.
- in parallel repair, some page flushes are not needed as done
by initialize_variables_for_repair().
storage/maria/ma_create.c:
Update skip_redo_lsn, create_rename_lsn optionally.
storage/maria/ma_delete_all.c:
Need to sync files at end of maria_delete_all_rows(), if transactional.
storage/maria/ma_extra.c:
During repair, we sometimes call _ma_flush_table_files() (via
_ma_flush_table_files_before_swap()) while there is a WRITE_CACHE.
storage/maria/ma_key_recover.c:
- when we see CLR_END for UNDO_BULK_INSERT_WITH_REPAIR, re-enable
indices.
- fixing bug: _ma_apply_undo_key_delete() parsed UNDO_KEY_DELETE_WITH_ROOT
wrongly, leading to recovery failure
storage/maria/ma_key_recover.h:
new prototype
storage/maria/ma_locking.c:
DBUG_VOID_RETURN missing
storage/maria/ma_loghandler.c:
UNDO for bulk insert with repair, and REDO for creating bitmaps.
LOGREC_FIRST_FREE to not have to change the for() every time we
add a new record type.
storage/maria/ma_loghandler.h:
new UNDO and REDO
storage/maria/ma_open.c:
Move share.kfile.file=kfile up a bit, so that _ma_update_state_lsns()
can get its value, this fixes a bug where LSN_REPAIRED_BY_MARIA_CHK
was not corrected on disk by maria_open().
Store skip_redo_lsn in index' header.
maria_enable_indexes() had a bug for BLOCK_RECORD, where an empty
file has one page, not 0 bytes.
storage/maria/ma_recovery.c:
- Skip a corrupted, missing, or repaired-with-maria_chk, table in
recovery: don't fail, just go to next REDO or UNDO; but if an UNDO
is skipped in UNDO phase we issue warnings.
- Skip REDO|UNDO in REDO phase if <skip_redo_lsn.
- If UNDO phase fails, delete transactions to not make trnman
assert.
- Update skip_redo_lsn when playing REDO_CREATE_TABLE
- Don't record UNDOs for old transactions which we don't know (long_trid==0)
- Bugfix for UNDO_KEY_DELETE_WITH_ROOT (see ma_key_recover.c)
- Execution of UNDO_BULK_INSERT_WITH_REPAIR
- Don't try to find a page number in REDO_DELETE_ALL
- Pieces moved to ma_recovery_util.c
storage/maria/ma_rename.c:
name change
storage/maria/ma_static.c:
I modified layout of the index' header (inserted skip_redo_lsn in its middle)
storage/maria/ma_test2.c:
allow breaking the test towards the end, tests execution of
UNDO_KEY_DELETE_WITH_ROOT
storage/maria/ma_test_recovery.expected:
6 as testflag instead of 4
storage/maria/ma_test_recovery:
Increase the amount of rollback work to do when testing recovery
with ma_test2; this reproduces the UNDO_KEY_DELETE_WITH_ROOT bug.
storage/maria/maria_chk.c:
skip_redo_lsn should be updated too, for consistency.
Write a REDO_REPAIR after all operations (including sort-records)
have been done.
No reason to flush blocks after maria_chk_data_link() and
maria_sort_records(), there is maria_close() in the end.
write_log_record() is a function, to not clutter maria_chk().
storage/maria/maria_def.h:
New member skip_redo_lsn in the state, and comments
storage/maria/maria_pack.c:
skip_redo_lsn should be updated too, for consistency
storage/maria/ma_recovery_util.c:
_ma_redo_not_needed_for_page(), defined in ma_recovery.c, is needed
by ma_blockrec.c; this causes link issues, resolved by putting
_ma_redo_not_needed_for_page() into a new file (so that it is not
in the same file as repair-related objects of ma_recovery.c).
storage/maria/ma_recovery_util.h:
new file

Added _ma_bitmap_wait_or_flush() to cause reader of bitmap pages to wait with reading until bitmap is flushed.
Use TAIL_PAGE_COUNT_MARKER for tail pages
Set 'sub_blocks' for and only for the head page or for the first extent of a blob. This is needed for store_extent_info() to be able to set START_EXTENT_BIT's
Don't allocate more than 0x3ffff pages in one extent (We need bit 0x4000 as a START_EXTENT_BIT)
Increase the calculated 'head_length' with the number of bytes used for extents.

storage/maria/ma_blockrec.c:
UNDO of rows now puts back all part of the row on their original pages and positions.

This changes a lot of logic as now an insert of a row on a page may happen to any position (and not just to the first or next free)
Use PAGE_COUNT to mark if an extent is the start of of a blob. (Needed for extent_to_bitmap_blocks())
Added check_directory() for checking that directroy entries are correct.
Added checking of row checksums when reading rows (with EXTRA_DEBUG)
Added make_space_for_directory() and extend_directory() for doing expansion of directory

Ensure allocation of tail blocks are of at least MIN_TAIL_SIZE.
Ensure we store pages in pinned pages even if read failed. (If not we will have pages pinned forever in page cache)
Write original extent information in UNDO entry, not compacted ones (we need position to tails!)
When setting BLOCKUSED_USED, don't clear other bits (we have to preserve BLOCKUSED_USE_ORG_BITMAP)
Fixed som bugs in directory handling
Fixed bug where we wrote wrong lsn to blob pages
Added separate blob_buffer for fixing bug when updating row that had char/varchar that spanned several pages and also had blobs
Ensure we call _ma_bitmap_flushable() also in case of errors
When doing an update, first delete old entries, then search in bitmap for where to put new information
Info->s -> share
Rowid -> rowid
More DBUG_ASSERT()

Added option -u to specify number of rows to update
Changed old option -u to be -A, as for ma_test1
Fixed bug in update of rows with blobs (before blobs was always reset to empty on update)
First created blob is now of max blob length to ensure we have at least one big blob in the table
storage/maria/ma_test_all.sh:
More tests
storage/maria/ma_test_recovery.expected:
Updated results
storage/maria/ma_test_recovery:
Changed tests to use bigger blobs (not just 1K)

Use PAGE_COUNT to mark if an extent is the start of of a blob. (Needed for extent_to_bitmap_blocks())
Added check_directory() for checking that directroy entries are correct.
Added checking of row checksums when reading rows (with EXTRA_DEBUG)
Added make_space_for_directory() and extend_directory() for doing expansion of directory

Changed _ma_apply_undo_row_delete() and _ma_apply_undo_row_update() to put row in it's original position
Ensure allocation of tail blocks are of at least MIN_TAIL_SIZE.
Ensure we store pages in pinned pages even if read failed. (If not we will have pages pinned forever in page cache)
Write original extent information in UNDO entry, not compacted ones (we need position to tails!)
When setting BLOCKUSED_USED, don't clear other bits (we have to preserve BLOCKUSED_USE_ORG_BITMAP)
Fixed som bugs in directory handling
Fixed bug where we wrote wrong lsn to blob pages
Added separate blob_buffer for fixing bug when updating row that had char/varchar that spanned several pages and also had blobs
Ensure we call _ma_bitmap_flushable() also in case of errors
When doing an update, first delete old entries, then search in bitmap for where to put new information
Info->s -> share
Rowid -> rowid
More DBUG_ASSERT()
storage/maria/ma_blockrec.h:
Added START_EXTENT_BIT and TAIL_PAGE_COUNT_MARKER
Added _ma_bitmap_wait_or_flush() and _ma_bitmap_get_page_bits()

Fixed bug where we logged uninitialized memory
storage/maria/ma_open.c:
Moved state->changed to be at start of state info on disk to allow one to easly mark files as crashed
storage/maria/ma_page.c:
Disable 'dummy' checksumming of pages as this gave false warnings.
(Need to investigate if this is ever needed)
storage/maria/ma_pagecache.c:
Fixed wrong shift that caused Maria to crash on files > 4G
storage/maria/ma_recovery.c:
In case of errors, start writing on new line if we where in %## %## printing mode (Made errors more readable)
Changed global variable name from warnings -> recovery_warnings
Use MARIA_FILE_CREATE_RENAME_LSN_OFFSET instead of constant
Removed special handling of row position for deleted keys. Keys now always includes row positions
_ma_apply_undo_row_delete() now gets page and row position
Added check that we don't loop forever when handling undo's (in case of bug in undo chain)
Print name of failed REDO/UNDO
storage/maria/ma_recovery.h:
Removed old comment
storage/maria/ma_static.c:
Chaned version number of Maria files to not accidently use old ones (becasue of change of ordering of status variables)
storage/maria/ma_test2.c:
Added option -u to specify number of rows to update
Changed old option -u to be -A, as for ma_test1
Fixed bug in update of rows with blobs (before blobs was always reset to empty on update)
First created blob is now of max blob length to ensure we have at least one big blob in the table
storage/maria/ma_test_all.sh:
More tests
storage/maria/ma_test_recovery.expected:
Updated results
storage/maria/ma_test_recovery:
Changed tests to use bigger blobs (not just 1K)
Added new tests that tests recovery of update with blobs
Removed comparision of .MAD file as it's not guranteed that recovery from scratch gives identical data file as original update
(compact_page() may be called at different times during normal execution and during REDO)
storage/maria/ma_update.c:
Simplify code (changed * to if)
storage/maria/maria_chk.c:
Make output more readable

Don't use 'non_flushable' marking of bitmap pages for not transactional tables
SHOW CREATE TABLE now shows if table was created with page checksums
Fixed a lot of bugs with BLOB handling in case of update/REDO and UNDO
More tests (especially for blobs) and DBUG_ASSERTS()

storage/maria/Makefile.am:
Added ma_test_big.sh
storage/maria/ha_maria.cc:
Store in create_info if page checksums are used (For SHOW CREATE TABLE)
storage/maria/ma_bitmap.c:
Added _ma_bitmap_wait_or_flush() to cause reader of bitmap pages to wait with reading until bitmap is flushed.
Use TAIL_PAGE_COUNT_MARKER for tail pages
Set 'sub_blocks' for and only for the head page or for the first extent of a blob. This is needed for store_extent_info() to be able to set START_EXTENT_BIT's
Don't allocate more than 0x3ffff pages in one extent (We need bit 0x4000 as a START_EXTENT_BIT)
Increase the calculated 'head_length' with the number of bytes used for extents.
Update row->space_on_head_page also in _ma_bitmap_find_new_place()
Make _ma_bitmap_get_page_bits() global. (Needed for UNDO handling)
Changed _ma_bitmap_flushable() to take MARIA_HA instead of MARIA_SHARE.
This was needed to be able to mark the handler if we had a 'non_flushable' call pending or not.
Don't use 'non_flushable' marking of bitmap pages for not transactional tables.
Added BLOCKUSED_USE_ORG_BITMAP handling also for tail pages.
Added more DBUG_ASSERT() to find possible errors in other code
Some code simplications by adding new local variables
storage/maria/ma_blockrec.c:
UNDO of rows now puts back all part of the row on their original pages and positions.
Changed UNDO of DELETE and UNDO of UPDATE to contain information about the original length of data on head block and also extent information
This changes a lot of logic as now an insert of a row on a page may happen to any position (and not just to the first or next free)
Use PAGE_COUNT to mark if an extent is the start of of a blob. (Needed for extent_to_bitmap_blocks())
Added check_directory() for checking that directroy entries are correct.
Added checking of row checksums when reading rows (with EXTRA_DEBUG)
Added make_space_for_directory() and extend_directory() for doing expansion of directory
Added get_rowpos_in_head_or_tail_page() to be able to store head/tail on original position in UNDO

Added _ma_update_at_original_place() for UNDO of DELETES
Added row->min_length to hold minmum required space needed on head page
Changed find_free_position() to use make_space_for_directory()
Changed make_empty_page() to allow optional creation of directory entry
Changed delete_head_or_tail() and _ma_apply_undo_row_isnert() to not copy pagecache block (speed optimization)
Changed _ma_apply_redo_insert_row_head_or_tail() to be able to insert new row at any position on 'new' page
Changed _ma_apply_undo_row_delete() and _ma_apply_undo_row_update() to put row in it's original position
Ensure allocation of tail blocks are of at least MIN_TAIL_SIZE.
Ensure we store pages in pinned pages even if read failed. (If not we will have pages pinned forever in page cache)
Write original extent information in UNDO entry, not compacted ones (we need position to tails!)
When setting BLOCKUSED_USED, don't clear other bits (we have to preserve BLOCKUSED_USE_ORG_BITMAP)
Fixed som bugs in directory handling
Fixed bug where we wrote wrong lsn to blob pages
Added separate blob_buffer for fixing bug when updating row that had char/varchar that spanned several pages and also had blobs
Ensure we call _ma_bitmap_flushable() also in case of errors
When doing an update, first delete old entries, then search in bitmap for where to put new information
Info->s -> share
Rowid -> rowid
More DBUG_ASSERT()
storage/maria/ma_blockrec.h:
Added START_EXTENT_BIT and TAIL_PAGE_COUNT_MARKER
Added _ma_bitmap_wait_or_flush() and _ma_bitmap_get_page_bits()
storage/maria/ma_check.c:
Don't write extra empty line if there is no deleted blocks
Ignore START_EXTENT_BIT's in page count
Call _ma_fast_unlock_key_del() to free key_del link
storage/maria/ma_close.c:
Ensure that used_key_del is 0. (If not, someone forgot to call _ma_unlock_key_del())

For deleted keys, log also position to row
storage/maria/ma_extra.c:
Release blob buffer at maria_reset() if bigger than MARIA_SMALL_BLOB_BUFFER

WL#3071 Maria checkpoint
Ability for flush_pagecache_blocks() to flush only certain pages of
a file, as instructed by an option "filter" pointer-to-function argument;
Checkpoint and background dirty page flushing use that to flush only
pages which have been dirty for long enough and bitmap pages.
Fix for a bug in flush_cached_blocks() (no idea if it could produce
a bug in real life, but theoretically it is).
Testing checkpoint in ma_test_recovery via ma_test1 and ma_test2.
Background checkpoint & dirty pages flush thread is still disabled
by default in ha_maria.
mysql-test/r/maria.result:
result update
storage/maria/ha_maria.cc:
blank after function comment
storage/maria/ma_checkpoint.c:
Using an enum instead of 0/1/2 (applying Sanja's review comments).
The comment about "this is an horizon" can be removed as Sanja
created translog_next_LSN() which parse_checkpoint_record() uses.
Variables in ma_checkpoint_background() cannot be declared in the
for() as their value must not be reset at each iteration!
storage/maria/ma_pagecache.c:
adding to flush_pagecache_blocks() optional arguments 'filter'
(pointer to function) and 'filter_arg'; if filter!=NULL this function
will be called for each block of the file and will reply if this
block and following ones should be flushed or not (3 possible
replies).
Fixing a bug when flush_cached_blocks() skips a pinned page: it has
to unset PCBLOCK_IN_FLUSH set by flush_pagecache_blocks_int().
storage/maria/ma_pagecache.h:
flush_pagecache_blocks() is changed to take "filter" and "filter_arg"
arguments. "filter", if it is not NULL, may return one value
among enum pagecache_flush_filter_result.
storage/maria/ma_recovery.c:
open_count=0 when closing tables at the end of recovery.
storage/maria/ma_test1.c:
Optional checkpoints (-H#) at various stages (stages similar
to --testflag), for testing of checkpoints.
storage/maria/ma_test2.c:
Optional checkpoints (-H#) at various stages (stages similar
to -t), for testing of checkpoints.
storage/maria/ma_test_recovery.expected:
Result update: the results of the additional test run with -H#
(checkpoints) are added here. They are exactly identical to without
checkpoints except that the index's Root (printed by maria_chk)
is more correct when using checkpoints. This is because checkpoint
flushed the state, so it happens to be correct, while no-checkpoint
does not flush the state, and recovery does not recover indexes
so Root is never fixed. When we recover indices, this will go away.
storage/maria/ma_test_recovery:
We duplicate the loop of tests to add an additional run with
checkpoints at various stages, to see if maria_read_log
uses them fine.

Added _ma_bitmap_wait_or_flush() to cause reader of bitmap pages to wait with reading until bitmap is flushed.
Use TAIL_PAGE_COUNT_MARKER for tail pages
Set 'sub_blocks' for and only for the head page or for the first extent of a blob. This is needed for store_extent_info() to be able to set START_EXTENT_BIT's
Don't allocate more than 0x3ffff pages in one extent (We need bit 0x4000 as a START_EXTENT_BIT)
Increase the calculated 'head_length' with the number of bytes used for extents.

storage/maria/ma_blockrec.c:
UNDO of rows now puts back all part of the row on their original pages and positions.

Ensure allocation of tail blocks are of at least MIN_TAIL_SIZE.
Ensure we store pages in pinned pages even if read failed. (If not we will have pages pinned forever in page cache)
Write original extent information in UNDO entry, not compacted ones (we need position to tails!)
When setting BLOCKUSED_USED, don't clear other bits (we have to preserve BLOCKUSED_USE_ORG_BITMAP)
Fixed som bugs in directory handling
Fixed bug where we wrote wrong lsn to blob pages
Added separate blob_buffer for fixing bug when updating row that had char/varchar that spanned several pages and also had blobs
Ensure we call _ma_bitmap_flushable() also in case of errors
When doing an update, first delete old entries, then search in bitmap for where to put new information
Info->s -> share
Rowid -> rowid
More DBUG_ASSERT()

Disable 'dummy' checksumming of pages as this gave false warnings.
(Need to investigate if this is ever needed)
storage/maria/ma_pagecache.c:
Fixed wrong shift that caused Maria to crash on files > 4G

Removed special handling of row position for deleted keys. Keys now always includes row positions
_ma_apply_undo_row_delete() now gets page and row position
Added check that we don't loop forever when handling undo's (in case of bug in undo chain)
Print name of failed REDO/UNDO
storage/maria/ma_recovery.h:
Removed old comment
storage/maria/ma_static.c:
Chaned version number of Maria files to not accidently use old ones (becasue of change of ordering of status variables)
storage/maria/ma_test2.c:
Added option -u to specify number of rows to update
Changed old option -u to be -A, as for ma_test1
Fixed bug in update of rows with blobs (before blobs was always reset to empty on update)
First created blob is now of max blob length to ensure we have at least one big blob in the table
storage/maria/ma_test_all.sh:
More tests
storage/maria/ma_test_recovery.expected:
Updated results
storage/maria/ma_test_recovery:
Changed tests to use bigger blobs (not just 1K)
Added new tests that tests recovery of update with blobs

WL#3071 Maria checkpoint
Ability for flush_pagecache_blocks() to flush only certain pages of
a file, as instructed by an option "filter" pointer-to-function argument;
Checkpoint and background dirty page flushing use that to flush only
pages which have been dirty for long enough and bitmap pages.
Fix for a bug in flush_cached_blocks() (no idea if it could produce
a bug in real life, but theoretically it is).
Testing checkpoint in ma_test_recovery via ma_test1 and ma_test2.
Background checkpoint & dirty pages flush thread is still disabled
by default in ha_maria.
mysql-test/r/maria.result:
result update
storage/maria/ha_maria.cc:
blank after function comment
storage/maria/ma_checkpoint.c:
Using an enum instead of 0/1/2 (applying Sanja's review comments).
The comment about "this is an horizon" can be removed as Sanja
created translog_next_LSN() which parse_checkpoint_record() uses.
Variables in ma_checkpoint_background() cannot be declared in the
for() as their value must not be reset at each iteration!
storage/maria/ma_pagecache.c:
adding to flush_pagecache_blocks() optional arguments 'filter'
(pointer to function) and 'filter_arg'; if filter!=NULL this function
will be called for each block of the file and will reply if this
block and following ones should be flushed or not (3 possible
replies).
Fixing a bug when flush_cached_blocks() skips a pinned page: it has
to unset PCBLOCK_IN_FLUSH set by flush_pagecache_blocks_int().
storage/maria/ma_pagecache.h:
flush_pagecache_blocks() is changed to take "filter" and "filter_arg"
arguments. "filter", if it is not NULL, may return one value
among enum pagecache_flush_filter_result.
storage/maria/ma_recovery.c:
open_count=0 when closing tables at the end of recovery.
storage/maria/ma_test1.c:
Optional checkpoints (-H#) at various stages (stages similar
to --testflag), for testing of checkpoints.
storage/maria/ma_test2.c:
Optional checkpoints (-H#) at various stages (stages similar
to -t), for testing of checkpoints.
storage/maria/ma_test_recovery.expected:
Result update: the results of the additional test run with -H#
(checkpoints) are added here. They are exactly identical to without
checkpoints except that the index's Root (printed by maria_chk)
is more correct when using checkpoints. This is because checkpoint
flushed the state, so it happens to be correct, while no-checkpoint
does not flush the state, and recovery does not recover indexes
so Root is never fixed. When we recover indices, this will go away.
storage/maria/ma_test_recovery:
We duplicate the loop of tests to add an additional run with
checkpoints at various stages, to see if maria_read_log
uses them fine.

WL#3071 Maria checkpoint
Ability for flush_pagecache_blocks() to flush only certain pages of
a file, as instructed by an option "filter" pointer-to-function argument;
Checkpoint and background dirty page flushing use that to flush only
pages which have been dirty for long enough and bitmap pages.
Fix for a bug in flush_cached_blocks() (no idea if it could produce
a bug in real life, but theoretically it is).
Testing checkpoint in ma_test_recovery via ma_test1 and ma_test2.
Background checkpoint & dirty pages flush thread is still disabled
by default in ha_maria.
mysql-test/r/maria.result:
result update
storage/maria/ha_maria.cc:
blank after function comment
storage/maria/ma_checkpoint.c:
Using an enum instead of 0/1/2 (applying Sanja's review comments).
The comment about "this is an horizon" can be removed as Sanja
created translog_next_LSN() which parse_checkpoint_record() uses.
Variables in ma_checkpoint_background() cannot be declared in the
for() as their value must not be reset at each iteration!
storage/maria/ma_pagecache.c:
adding to flush_pagecache_blocks() optional arguments 'filter'
(pointer to function) and 'filter_arg'; if filter!=NULL this function
will be called for each block of the file and will reply if this
block and following ones should be flushed or not (3 possible
replies).
Fixing a bug when flush_cached_blocks() skips a pinned page: it has
to unset PCBLOCK_IN_FLUSH set by flush_pagecache_blocks_int().
storage/maria/ma_pagecache.h:
flush_pagecache_blocks() is changed to take "filter" and "filter_arg"
arguments. "filter", if it is not NULL, may return one value
among enum pagecache_flush_filter_result.
storage/maria/ma_recovery.c:
open_count=0 when closing tables at the end of recovery.
storage/maria/ma_test1.c:
Optional checkpoints (-H#) at various stages (stages similar
to --testflag), for testing of checkpoints.
storage/maria/ma_test2.c:
Optional checkpoints (-H#) at various stages (stages similar
to -t), for testing of checkpoints.
storage/maria/ma_test_recovery.expected:
Result update: the results of the additional test run with -H#
(checkpoints) are added here. They are exactly identical to without
checkpoints except that the index's Root (printed by maria_chk)
is more correct when using checkpoints. This is because checkpoint
flushed the state, so it happens to be correct, while no-checkpoint
does not flush the state, and recovery does not recover indexes
so Root is never fixed. When we recover indices, this will go away.
storage/maria/ma_test_recovery:
We duplicate the loop of tests to add an additional run with
checkpoints at various stages, to see if maria_read_log
uses them fine.

Use TAIL_PAGE_COUNT_MARKER for tail pages
Set 'sub_blocks' for and only for the head page or for the first extent of a blob. This is needed for store_extent_info() to be able to set START_EXTENT_BIT's
Don't allocate more than 0x3ffff pages in one extent (We need bit 0x4000 as a START_EXTENT_BIT)
Increase the calculated 'head_length' with the number of bytes used for extents.
Update row->space_on_head_page also in _ma_bitmap_find_new_place()

Fixed som bugs in directory handling
Fixed bug where we wrote wrong lsn to blob pages
Added separate blob_buffer for fixing bug when updating row that had char/varchar that spanned several pages and also had blobs

First created blob is now of max blob length to ensure we have at least one big blob in the table
storage/maria/ma_test_all.sh:
More tests
storage/maria/ma_test_recovery.expected:
Updated results
storage/maria/ma_test_recovery:
Changed tests to use bigger blobs (not just 1K)
Added new tests that tests recovery of update with blobs
Removed comparision of .MAD file as it's not guranteed that recovery from scratch gives identical data file as original update

Simplify code (changed * to if)
storage/maria/maria_chk.c:
Make output more readable

Use TAIL_PAGE_COUNT_MARKER for tail pages
Set 'sub_blocks' for and only for the head page or for the first extent of a blob. This is needed for store_extent_info() to be able to set START_EXTENT_BIT's
Don't allocate more than 0x3ffff pages in one extent (We need bit 0x4000 as a START_EXTENT_BIT)
Increase the calculated 'head_length' with the number of bytes used for extents.

Ensure allocation of tail blocks are of at least MIN_TAIL_SIZE.
Ensure we store pages in pinned pages even if read failed. (If not we will have pages pinned forever in page cache)
Write original extent information in UNDO entry, not compacted ones (we need position to tails!)

Fixed som bugs in directory handling
Fixed bug where we wrote wrong lsn to blob pages
Added separate blob_buffer for fixing bug when updating row that had char/varchar that spanned several pages and also had blobs

UNDO of rows now puts back all part of the row on their original pages and positions
Added variable _dbug_on_ to speed up execution when DBUG is not going to be used
Added --debug-on option to mysqld (to be able to turn of DBUG with --debug-on=0)
Fixed some bugs with 'non_flushable' marking of bitmap pages
Don't use 'non_flushable' marking of bitmap pages for not transactional tables
SHOW CREATE TABLE now shows if table was created with page checksums
Fixed a lot of bugs with BLOB handling in case of update/REDO and UNDO
More tests (especially for blobs) and DBUG_ASSERTS()
More readable output from maria_read_log and maria_chk
Fixed wrong shift that caused Maria to crash on files > 4G
Mark tables as crashed of REDO fails
dbug/dbug.c:
Changed to use my_bool (allowed me to remove some windows specific code)
Added variable _dbug_on_ to speed up execution when DBUG is not going to be used
Removed initialization of variables if not needed
include/my_dbug.h:
Use my_bool for some functions that was defined as BOOLEAN in dbug.c code
Added DBUGGER_ON/DEBUGGER_OFF to speed up execution when DBUG is not used

Define my_bool early
Increase MY_HOW_OFTEN_TO_WRITE as computers are now faster than 10 years ago

Added debug-on=0 to speed up tests
mysql-test/r/maria-recovery.result:

storage/maria/Makefile.am:
Added ma_test_big.sh
storage/maria/ha_maria.cc:
Store in create_info if page checksums are used (For SHOW CREATE TABLE)
storage/maria/ma_bitmap.c:
Added _ma_bitmap_wait_or_flush() to cause reader of bitmap pages to wait with reading until bitmap is flushed.
Use TAIL_PAGE_COUNT_MARKER for tail pages
Set 'sub_blocks' for and only for the head page or for the first extent of a blob. This is needed for store_extent_info() to be able to set START_EXTENT_BIT's
Don't allocate more than 0x3ffff pages in one extent (We need bit 0x4000 as a START_EXTENT_BIT)
Increase the calculated 'head_length' with the number of bytes used for extents.
Update row->space_on_head_page also in _ma_bitmap_find_new_place()
Make _ma_bitmap_get_page_bits() global. (Needed for UNDO handling)

This was needed to be able to mark the handler if we had a 'non_flushable' call pending or not.
Don't use 'non_flushable' marking of bitmap pages for not transactional tables.
Added BLOCKUSED_USE_ORG_BITMAP handling also for tail pages.
Added more DBUG_ASSERT() to find possible errors in other code
Some code simplications by adding new local variables
storage/maria/ma_blockrec.c:
UNDO of rows now puts back all part of the row on their original pages and positions.
Changed UNDO of DELETE and UNDO of UPDATE to contain information about the original length of data on head block and also extent information
This changes a lot of logic as now an insert of a row on a page may happen to any position (and not just to the first or next free)
Use PAGE_COUNT to mark if an extent is the start of of a blob. (Needed for extent_to_bitmap_blocks())
Added check_directory() for checking that directroy entries are correct.
Added checking of row checksums when reading rows (with EXTRA_DEBUG)
Added make_space_for_directory() and extend_directory() for doing expansion of directory
Added get_rowpos_in_head_or_tail_page() to be able to store head/tail on original position in UNDO

Added row->min_length to hold minmum required space needed on head page
Changed find_free_position() to use make_space_for_directory()
Changed make_empty_page() to allow optional creation of directory entry
Changed delete_head_or_tail() and _ma_apply_undo_row_isnert() to not copy pagecache block (speed optimization)
Changed _ma_apply_redo_insert_row_head_or_tail() to be able to insert new row at any position on 'new' page
Changed _ma_apply_undo_row_delete() and _ma_apply_undo_row_update() to put row in it's original position
Ensure allocation of tail blocks are of at least MIN_TAIL_SIZE.
Ensure we store pages in pinned pages even if read failed. (If not we will have pages pinned forever in page cache)
Write original extent information in UNDO entry, not compacted ones (we need position to tails!)
When setting BLOCKUSED_USED, don't clear other bits (we have to preserve BLOCKUSED_USE_ORG_BITMAP)
Fixed som bugs in directory handling
Fixed bug where we wrote wrong lsn to blob pages
Added separate blob_buffer for fixing bug when updating row that had char/varchar that spanned several pages and also had blobs
Ensure we call _ma_bitmap_flushable() also in case of errors
When doing an update, first delete old entries, then search in bitmap for where to put new information

WL#3072 - Maria Recovery
Bulk insert: don't log REDO/UNDO for rows, log one UNDO which will
truncate files; this is an optimization and a bugfix (table was left
half-repaired by crash).
Repair: mark table crashed-on-repair at start, bump skip_redo_lsn at start,
this is easier for recovery (tells it to skip old REDOs or even UNDO
phase) and user (tells it to repair) in case of crash, sync files
in the end.
Recovery skips missing or corrupted table and moves to next record
(in REDO or UNDO phase) to be more robust; warns if happens in UNDO phase.
Bugfix for UNDO_KEY_DELETE_WITH_ROOT (tested in ma_test_recovery)
and maria_enable_indexes().
Create missing bitmaps when needed (there can be more than one to create,
in rare cases), log a record for this.
include/myisamchk.h:
new flag: bulk insert repair mustn't bump create_rename_lsn
mysql-test/lib/mtr_report.pl:
skip normal warning in maria-recovery.test
mysql-test/r/maria-recovery.result:
result: crash before bulk insert is committed, causes proper rollback,
and crash right after OPTIMIZE replaces index file with new index file
leads to table marked corrupted and recovery not failing.
mysql-test/t/maria-recovery.test:
- can't check the table or it would commit the transaction,
but check is made after recovery.
- test of crash before bulk-insert-with-repair is committed
(to see if it is rolled back), and of crash after OPTIMIZE has replaced
index file but not finished all operations (to see if recovery fails -
it used to assert when trying to execute an old REDO on the new
index).
storage/maria/CMakeLists.txt:
new file
storage/maria/Makefile.am:
new file
storage/maria/ha_maria.cc:
- If bulk insert on a transactional table using an index repair:
table is initially empty, so don't log REDO/UNDO for data rows
(optimization), just log an UNDO_BULK_INSERT_WITH_REPAIR
which will, if executed, empty the data and index file. Re-enable
logging in end_bulk_insert().
- write log record for repair operation only after it's fully done,
index sort including (maria_repair*() used to write the log record).
- Adding back file->trn=NULL which was removed by mistake earlier.
storage/maria/ha_maria.h:
new member (see ha_maria.cc)
storage/maria/ma_bitmap.c:
Functions to create missing bitmaps:
- one function which creates missing bitmaps in page cache, except
the missing one with max offset which it does not put into page cache
as it will be modified very soon.
- one function which the one above calls, and creates bitmaps in page
cache
- one function to execute REDO_BITMAP_NEW_PAGE which uses the second
one above.
storage/maria/ma_blockrec.c:
- when logging REDO_DELETE_ALL, not only 'records' and 'checksum'
has to be reset under log's mutex.
- execution of REDO_INSERT_ROW_BLOBS now checks the dirty pages' list
- execution of UNDO_BULK_INSERT_WITH_REPAIR
storage/maria/ma_blockrec.h:
new functions
storage/maria/ma_check.c:
- table-flush-before-repair is moved to a separate function reused
by maria_sort_index(); syncing is added
- maria_repair() is allowed to re-enable logging only if it is the one
which disabled it.
- "_ma_flush_table_files_after_repair" was a bad name, it's not after
repair now, and it should not sync as we do more changes to the files
shortly after (sync is postponed to when writing the log record)
- REDO_REPAIR record should be written only after all repair
operations (in particular after sorting index in ha_mara::repair())
- close to the end of repair by sort, flushing of pages must happen
also in the non-quick case, to prepare for the sync at end.
- in parallel repair, some page flushes are not needed as done
by initialize_variables_for_repair().
storage/maria/ma_create.c:
Update skip_redo_lsn, create_rename_lsn optionally.
storage/maria/ma_delete_all.c:
Need to sync files at end of maria_delete_all_rows(), if transactional.
storage/maria/ma_extra.c:
During repair, we sometimes call _ma_flush_table_files() (via
_ma_flush_table_files_before_swap()) while there is a WRITE_CACHE.
storage/maria/ma_key_recover.c:
- when we see CLR_END for UNDO_BULK_INSERT_WITH_REPAIR, re-enable
indices.
- fixing bug: _ma_apply_undo_key_delete() parsed UNDO_KEY_DELETE_WITH_ROOT
wrongly, leading to recovery failure
storage/maria/ma_key_recover.h:
new prototype
storage/maria/ma_locking.c:
DBUG_VOID_RETURN missing
storage/maria/ma_loghandler.c:
UNDO for bulk insert with repair, and REDO for creating bitmaps.
LOGREC_FIRST_FREE to not have to change the for() every time we
add a new record type.
storage/maria/ma_loghandler.h:
new UNDO and REDO
storage/maria/ma_open.c:
Move share.kfile.file=kfile up a bit, so that _ma_update_state_lsns()
can get its value, this fixes a bug where LSN_REPAIRED_BY_MARIA_CHK
was not corrected on disk by maria_open().
Store skip_redo_lsn in index' header.
maria_enable_indexes() had a bug for BLOCK_RECORD, where an empty
file has one page, not 0 bytes.
storage/maria/ma_recovery.c:
- Skip a corrupted, missing, or repaired-with-maria_chk, table in
recovery: don't fail, just go to next REDO or UNDO; but if an UNDO
is skipped in UNDO phase we issue warnings.
- Skip REDO|UNDO in REDO phase if <skip_redo_lsn.
- If UNDO phase fails, delete transactions to not make trnman
assert.
- Update skip_redo_lsn when playing REDO_CREATE_TABLE
- Don't record UNDOs for old transactions which we don't know (long_trid==0)
- Bugfix for UNDO_KEY_DELETE_WITH_ROOT (see ma_key_recover.c)
- Execution of UNDO_BULK_INSERT_WITH_REPAIR
- Don't try to find a page number in REDO_DELETE_ALL
- Pieces moved to ma_recovery_util.c
storage/maria/ma_rename.c:
name change
storage/maria/ma_static.c:
I modified layout of the index' header (inserted skip_redo_lsn in its middle)
storage/maria/ma_test2.c:
allow breaking the test towards the end, tests execution of
UNDO_KEY_DELETE_WITH_ROOT
storage/maria/ma_test_recovery.expected:
6 as testflag instead of 4
storage/maria/ma_test_recovery:
Increase the amount of rollback work to do when testing recovery
with ma_test2; this reproduces the UNDO_KEY_DELETE_WITH_ROOT bug.
storage/maria/maria_chk.c:
skip_redo_lsn should be updated too, for consistency.
Write a REDO_REPAIR after all operations (including sort-records)
have been done.
No reason to flush blocks after maria_chk_data_link() and
maria_sort_records(), there is maria_close() in the end.
write_log_record() is a function, to not clutter maria_chk().
storage/maria/maria_def.h:
New member skip_redo_lsn in the state, and comments
storage/maria/maria_pack.c:
skip_redo_lsn should be updated too, for consistency
storage/maria/ma_recovery_util.c:
_ma_redo_not_needed_for_page(), defined in ma_recovery.c, is needed
by ma_blockrec.c; this causes link issues, resolved by putting
_ma_redo_not_needed_for_page() into a new file (so that it is not
in the same file as repair-related objects of ma_recovery.c).
storage/maria/ma_recovery_util.h:

WL#3071 Maria checkpoint
Ability for flush_pagecache_blocks() to flush only certain pages of
a file, as instructed by an option "filter" pointer-to-function argument;
Checkpoint and background dirty page flushing use that to flush only
pages which have been dirty for long enough and bitmap pages.
Fix for a bug in flush_cached_blocks() (no idea if it could produce
a bug in real life, but theoretically it is).
Testing checkpoint in ma_test_recovery via ma_test1 and ma_test2.
Background checkpoint & dirty pages flush thread is still disabled

storage/maria/ma_checkpoint.c:
Using an enum instead of 0/1/2 (applying Sanja's review comments).
The comment about "this is an horizon" can be removed as Sanja
created translog_next_LSN() which parse_checkpoint_record() uses.
Variables in ma_checkpoint_background() cannot be declared in the
for() as their value must not be reset at each iteration!
storage/maria/ma_pagecache.c:
adding to flush_pagecache_blocks() optional arguments 'filter'
(pointer to function) and 'filter_arg'; if filter!=NULL this function
will be called for each block of the file and will reply if this
block and following ones should be flushed or not (3 possible
replies).
Fixing a bug when flush_cached_blocks() skips a pinned page: it has
to unset PCBLOCK_IN_FLUSH set by flush_pagecache_blocks_int().
storage/maria/ma_pagecache.h:
flush_pagecache_blocks() is changed to take "filter" and "filter_arg"
arguments. "filter", if it is not NULL, may return one value
among enum pagecache_flush_filter_result.
storage/maria/ma_recovery.c:

storage/maria/ma_test1.c:
Optional checkpoints (-H#) at various stages (stages similar

storage/maria/ma_test_recovery.expected:
Result update: the results of the additional test run with -H#
(checkpoints) are added here. They are exactly identical to without
checkpoints except that the index's Root (printed by maria_chk)
is more correct when using checkpoints. This is because checkpoint
flushed the state, so it happens to be correct, while no-checkpoint
does not flush the state, and recovery does not recover indexes
so Root is never fixed. When we recover indices, this will go away.
storage/maria/ma_test_recovery:
We duplicate the loop of tests to add an additional run with
checkpoints at various stages, to see if maria_read_log
uses them fine.

Ensure we store pages in pinned pages even if read failed. (If not we will have pages pinned forever in page cache)
Write original extent information in UNDO entry, not compacted ones (we need position to tails!)
When setting BLOCKUSED_USED, don't clear other bits (we have to preserve BLOCKUSED_USE_ORG_BITMAP)
Fixed som bugs in directory handling
Fixed bug where we wrote wrong lsn to blob pages
Added separate blob_buffer for fixing bug when updating row that had char/varchar that spanned several pages and also had blobs

Added option -u to specify number of rows to update
Changed old option -u to be -A, as for ma_test1

First created blob is now of max blob length to ensure we have at least one big blob in the table
storage/maria/ma_test_all.sh:
More tests
storage/maria/ma_test_recovery.expected:
Updated results
storage/maria/ma_test_recovery:
Changed tests to use bigger blobs (not just 1K)

WL#3071 Maria checkpoint
Ability for flush_pagecache_blocks() to flush only certain pages of
a file, as instructed by an option "filter" pointer-to-function argument;
Checkpoint and background dirty page flushing use that to flush only
pages which have been dirty for long enough and bitmap pages.
Fix for a bug in flush_cached_blocks() (no idea if it could produce
a bug in real life, but theoretically it is).
Testing checkpoint in ma_test_recovery via ma_test1 and ma_test2.
Background checkpoint & dirty pages flush thread is still disabled
by default in ha_maria.
mysql-test/r/maria.result:
result update
storage/maria/ha_maria.cc:
blank after function comment
storage/maria/ma_checkpoint.c:
Using an enum instead of 0/1/2 (applying Sanja's review comments).
The comment about "this is an horizon" can be removed as Sanja
created translog_next_LSN() which parse_checkpoint_record() uses.
Variables in ma_checkpoint_background() cannot be declared in the
for() as their value must not be reset at each iteration!
storage/maria/ma_pagecache.c:
adding to flush_pagecache_blocks() optional arguments 'filter'
(pointer to function) and 'filter_arg'; if filter!=NULL this function
will be called for each block of the file and will reply if this
block and following ones should be flushed or not (3 possible
replies).
Fixing a bug when flush_cached_blocks() skips a pinned page: it has
to unset PCBLOCK_IN_FLUSH set by flush_pagecache_blocks_int().
storage/maria/ma_pagecache.h:
flush_pagecache_blocks() is changed to take "filter" and "filter_arg"
arguments. "filter", if it is not NULL, may return one value
among enum pagecache_flush_filter_result.
storage/maria/ma_recovery.c:
open_count=0 when closing tables at the end of recovery.
storage/maria/ma_test1.c:
Optional checkpoints (-H#) at various stages (stages similar
to --testflag), for testing of checkpoints.
storage/maria/ma_test2.c:
Optional checkpoints (-H#) at various stages (stages similar
to -t), for testing of checkpoints.
storage/maria/ma_test_recovery.expected:
Result update: the results of the additional test run with -H#
(checkpoints) are added here. They are exactly identical to without
checkpoints except that the index's Root (printed by maria_chk)
is more correct when using checkpoints. This is because checkpoint
flushed the state, so it happens to be correct, while no-checkpoint
does not flush the state, and recovery does not recover indexes
so Root is never fixed. When we recover indices, this will go away.
storage/maria/ma_test_recovery:
We duplicate the loop of tests to add an additional run with
checkpoints at various stages, to see if maria_read_log
uses them fine.

Ensure allocation of tail blocks are of at least MIN_TAIL_SIZE.
Ensure we store pages in pinned pages even if read failed. (If not we will have pages pinned forever in page cache)
Write original extent information in UNDO entry, not compacted ones (we need position to tails!)
When setting BLOCKUSED_USED, don't clear other bits (we have to preserve BLOCKUSED_USE_ORG_BITMAP)
Fixed som bugs in directory handling
Fixed bug where we wrote wrong lsn to blob pages
Added separate blob_buffer for fixing bug when updating row that had char/varchar that spanned several pages and also had blobs

Updated results
storage/maria/ma_test_recovery:
Changed tests to use bigger blobs (not just 1K)

WL#3071 Maria checkpoint
Ability for flush_pagecache_blocks() to flush only certain pages of
a file, as instructed by an option "filter" pointer-to-function argument;
Checkpoint and background dirty page flushing use that to flush only
pages which have been dirty for long enough and bitmap pages.
Fix for a bug in flush_cached_blocks() (no idea if it could produce
a bug in real life, but theoretically it is).
Testing checkpoint in ma_test_recovery via ma_test1 and ma_test2.
Background checkpoint & dirty pages flush thread is still disabled
by default in ha_maria.
mysql-test/r/maria.result:
result update
storage/maria/ha_maria.cc:
blank after function comment
storage/maria/ma_checkpoint.c:
Using an enum instead of 0/1/2 (applying Sanja's review comments).
The comment about "this is an horizon" can be removed as Sanja
created translog_next_LSN() which parse_checkpoint_record() uses.
Variables in ma_checkpoint_background() cannot be declared in the
for() as their value must not be reset at each iteration!
storage/maria/ma_pagecache.c:
adding to flush_pagecache_blocks() optional arguments 'filter'
(pointer to function) and 'filter_arg'; if filter!=NULL this function
will be called for each block of the file and will reply if this
block and following ones should be flushed or not (3 possible
replies).
Fixing a bug when flush_cached_blocks() skips a pinned page: it has
to unset PCBLOCK_IN_FLUSH set by flush_pagecache_blocks_int().
storage/maria/ma_pagecache.h:
flush_pagecache_blocks() is changed to take "filter" and "filter_arg"
arguments. "filter", if it is not NULL, may return one value
among enum pagecache_flush_filter_result.
storage/maria/ma_recovery.c:
open_count=0 when closing tables at the end of recovery.
storage/maria/ma_test1.c:
Optional checkpoints (-H#) at various stages (stages similar
to --testflag), for testing of checkpoints.
storage/maria/ma_test2.c:
Optional checkpoints (-H#) at various stages (stages similar
to -t), for testing of checkpoints.
storage/maria/ma_test_recovery.expected:
Result update: the results of the additional test run with -H#
(checkpoints) are added here. They are exactly identical to without
checkpoints except that the index's Root (printed by maria_chk)
is more correct when using checkpoints. This is because checkpoint
flushed the state, so it happens to be correct, while no-checkpoint
does not flush the state, and recovery does not recover indexes
so Root is never fixed. When we recover indices, this will go away.
storage/maria/ma_test_recovery:
We duplicate the loop of tests to add an additional run with
checkpoints at various stages, to see if maria_read_log
uses them fine.

UNDO of rows now puts back all part of the row on their original pages and positions
Added variable _dbug_on_ to speed up execution when DBUG is not going to be used
Added --debug-on option to mysqld (to be able to turn of DBUG with --debug-on=0)
Fixed some bugs with 'non_flushable' marking of bitmap pages
Don't use 'non_flushable' marking of bitmap pages for not transactional tables
SHOW CREATE TABLE now shows if table was created with page checksums
Fixed a lot of bugs with BLOB handling in case of update/REDO and UNDO
More tests (especially for blobs) and DBUG_ASSERTS()
More readable output from maria_read_log and maria_chk
Fixed wrong shift that caused Maria to crash on files > 4G
Mark tables as crashed of REDO fails
dbug/dbug.c:
Changed to use my_bool (allowed me to remove some windows specific code)
Added variable _dbug_on_ to speed up execution when DBUG is not going to be used
Removed initialization of variables if not needed
include/my_dbug.h:
Use my_bool for some functions that was defined as BOOLEAN in dbug.c code
Added DBUGGER_ON/DEBUGGER_OFF to speed up execution when DBUG is not used
include/my_global.h:
Define my_bool early
Increase MY_HOW_OFTEN_TO_WRITE as computers are now faster than 10 years ago
mysql-test/mysql-test-run.pl:
Added debug-on=0 to speed up tests
mysql-test/r/maria-recovery.result:

Added testing of page checksums
sql/mysqld.cc:
Added --debug-on option (to be able to turn of DBUG with --debug-on=0)
Indentation fixes
Removed end spaces
sql/sql_show.cc:
Allow update_create_info() to inform MySQL if PACK_KEYS, NO_PACK_KEYS, CHECKSUM, PAGE_CHECKSUM or DELAY_KEY_WRITE is used
storage/maria/Makefile.am:
Added ma_test_big.sh
storage/maria/ha_maria.cc:
Store in create_info if page checksums are used (For SHOW CREATE TABLE)
storage/maria/ma_bitmap.c:
Added _ma_bitmap_wait_or_flush() to cause reader of bitmap pages to wait with reading until bitmap is flushed.
Use TAIL_PAGE_COUNT_MARKER for tail pages
Set 'sub_blocks' for and only for the head page or for the first extent of a blob. This is needed for store_extent_info() to be able to set START_EXTENT_BIT's
Don't allocate more than 0x3ffff pages in one extent (We need bit 0x4000 as a START_EXTENT_BIT)
Increase the calculated 'head_length' with the number of bytes used for extents.
Update row->space_on_head_page also in _ma_bitmap_find_new_place()
Make _ma_bitmap_get_page_bits() global. (Needed for UNDO handling)
Changed _ma_bitmap_flushable() to take MARIA_HA instead of MARIA_SHARE.
This was needed to be able to mark the handler if we had a 'non_flushable' call pending or not.
Don't use 'non_flushable' marking of bitmap pages for not transactional tables.
Added BLOCKUSED_USE_ORG_BITMAP handling also for tail pages.
Added more DBUG_ASSERT() to find possible errors in other code
Some code simplications by adding new local variables
storage/maria/ma_blockrec.c:
UNDO of rows now puts back all part of the row on their original pages and positions.
Changed UNDO of DELETE and UNDO of UPDATE to contain information about the original length of data on head block and also extent information
This changes a lot of logic as now an insert of a row on a page may happen to any position (and not just to the first or next free)
Use PAGE_COUNT to mark if an extent is the start of of a blob. (Needed for extent_to_bitmap_blocks())
Added check_directory() for checking that directroy entries are correct.
Added checking of row checksums when reading rows (with EXTRA_DEBUG)
Added make_space_for_directory() and extend_directory() for doing expansion of directory
Added get_rowpos_in_head_or_tail_page() to be able to store head/tail on original position in UNDO
Added extent_to_bitmap_blocks() to be able to generate original bitmap blocks from UNDO entry
Added _ma_update_at_original_place() for UNDO of DELETES
Added row->min_length to hold minmum required space needed on head page
Changed find_free_position() to use make_space_for_directory()
Changed make_empty_page() to allow optional creation of directory entry
Changed delete_head_or_tail() and _ma_apply_undo_row_isnert() to not copy pagecache block (speed optimization)
Changed _ma_apply_redo_insert_row_head_or_tail() to be able to insert new row at any position on 'new' page
Changed _ma_apply_undo_row_delete() and _ma_apply_undo_row_update() to put row in it's original position
Ensure allocation of tail blocks are of at least MIN_TAIL_SIZE.

UNDO of rows now puts back all part of the row on their original pages and positions
Added variable _dbug_on_ to speed up execution when DBUG is not going to be used
Added --debug-on option to mysqld (to be able to turn of DBUG with --debug-on=0)
Fixed some bugs with 'non_flushable' marking of bitmap pages
Don't use 'non_flushable' marking of bitmap pages for not transactional tables
SHOW CREATE TABLE now shows if table was created with page checksums
Fixed a lot of bugs with BLOB handling in case of update/REDO and UNDO
More tests (especially for blobs) and DBUG_ASSERTS()
More readable output from maria_read_log and maria_chk
Fixed wrong shift that caused Maria to crash on files > 4G
Mark tables as crashed of REDO fails
dbug/dbug.c:
Changed to use my_bool (allowed me to remove some windows specific code)
Added variable _dbug_on_ to speed up execution when DBUG is not going to be used
Removed initialization of variables if not needed
include/my_dbug.h:
Use my_bool for some functions that was defined as BOOLEAN in dbug.c code

storage/maria/Makefile.am:
Added ma_test_big.sh
storage/maria/ha_maria.cc:
Store in create_info if page checksums are used (For SHOW CREATE TABLE)
storage/maria/ma_bitmap.c:
Added _ma_bitmap_wait_or_flush() to cause reader of bitmap pages to wait with reading until bitmap is flushed.
Use TAIL_PAGE_COUNT_MARKER for tail pages
Set 'sub_blocks' for and only for the head page or for the first extent of a blob. This is needed for store_extent_info() to be able to set START_EXTENT_BIT's
Don't allocate more than 0x3ffff pages in one extent (We need bit 0x4000 as a START_EXTENT_BIT)
Increase the calculated 'head_length' with the number of bytes used for extents.
Update row->space_on_head_page also in _ma_bitmap_find_new_place()
Make _ma_bitmap_get_page_bits() global. (Needed for UNDO handling)
Changed _ma_bitmap_flushable() to take MARIA_HA instead of MARIA_SHARE.
This was needed to be able to mark the handler if we had a 'non_flushable' call pending or not.

Added BLOCKUSED_USE_ORG_BITMAP handling also for tail pages.
Added more DBUG_ASSERT() to find possible errors in other code
Some code simplications by adding new local variables
storage/maria/ma_blockrec.c:
UNDO of rows now puts back all part of the row on their original pages and positions.
Changed UNDO of DELETE and UNDO of UPDATE to contain information about the original length of data on head block and also extent information
This changes a lot of logic as now an insert of a row on a page may happen to any position (and not just to the first or next free)
Use PAGE_COUNT to mark if an extent is the start of of a blob. (Needed for extent_to_bitmap_blocks())
Added check_directory() for checking that directroy entries are correct.
Added checking of row checksums when reading rows (with EXTRA_DEBUG)
Added make_space_for_directory() and extend_directory() for doing expansion of directory
Added get_rowpos_in_head_or_tail_page() to be able to store head/tail on original position in UNDO

Changed delete_head_or_tail() and _ma_apply_undo_row_isnert() to not copy pagecache block (speed optimization)
Changed _ma_apply_redo_insert_row_head_or_tail() to be able to insert new row at any position on 'new' page
Changed _ma_apply_undo_row_delete() and _ma_apply_undo_row_update() to put row in it's original position
Ensure allocation of tail blocks are of at least MIN_TAIL_SIZE.
Ensure we store pages in pinned pages even if read failed. (If not we will have pages pinned forever in page cache)
Write original extent information in UNDO entry, not compacted ones (we need position to tails!)
When setting BLOCKUSED_USED, don't clear other bits (we have to preserve BLOCKUSED_USE_ORG_BITMAP)

Store in create_info if page checksums are used (For SHOW CREATE TABLE)
storage/maria/ma_bitmap.c:
Added _ma_bitmap_wait_or_flush() to cause reader of bitmap pages to wait with reading until bitmap is flushed.
Use TAIL_PAGE_COUNT_MARKER for tail pages
Set 'sub_blocks' for and only for the head page or for the first extent of a blob. This is needed for store_extent_info() to be able to set START_EXTENT_BIT's
Don't allocate more than 0x3ffff pages in one extent (We need bit 0x4000 as a START_EXTENT_BIT)
Increase the calculated 'head_length' with the number of bytes used for extents.
Update row->space_on_head_page also in _ma_bitmap_find_new_place()
Make _ma_bitmap_get_page_bits() global. (Needed for UNDO handling)
Changed _ma_bitmap_flushable() to take MARIA_HA instead of MARIA_SHARE.
This was needed to be able to mark the handler if we had a 'non_flushable' call pending or not.
Don't use 'non_flushable' marking of bitmap pages for not transactional tables.
Added BLOCKUSED_USE_ORG_BITMAP handling also for tail pages.
Added more DBUG_ASSERT() to find possible errors in other code
Some code simplications by adding new local variables
storage/maria/ma_blockrec.c:
UNDO of rows now puts back all part of the row on their original pages and positions.
Changed UNDO of DELETE and UNDO of UPDATE to contain information about the original length of data on head block and also extent information
This changes a lot of logic as now an insert of a row on a page may happen to any position (and not just to the first or next free)
Use PAGE_COUNT to mark if an extent is the start of of a blob. (Needed for extent_to_bitmap_blocks())
Added check_directory() for checking that directroy entries are correct.
Added checking of row checksums when reading rows (with EXTRA_DEBUG)
Added make_space_for_directory() and extend_directory() for doing expansion of directory
Added get_rowpos_in_head_or_tail_page() to be able to store head/tail on original position in UNDO
Added extent_to_bitmap_blocks() to be able to generate original bitmap blocks from UNDO entry
Added _ma_update_at_original_place() for UNDO of DELETES
Added row->min_length to hold minmum required space needed on head page
Changed find_free_position() to use make_space_for_directory()
Changed make_empty_page() to allow optional creation of directory entry
Changed delete_head_or_tail() and _ma_apply_undo_row_isnert() to not copy pagecache block (speed optimization)
Changed _ma_apply_redo_insert_row_head_or_tail() to be able to insert new row at any position on 'new' page
Changed _ma_apply_undo_row_delete() and _ma_apply_undo_row_update() to put row in it's original position
Ensure allocation of tail blocks are of at least MIN_TAIL_SIZE.
Ensure we store pages in pinned pages even if read failed. (If not we will have pages pinned forever in page cache)
Write original extent information in UNDO entry, not compacted ones (we need position to tails!)
When setting BLOCKUSED_USED, don't clear other bits (we have to preserve BLOCKUSED_USE_ORG_BITMAP)
Fixed som bugs in directory handling
Fixed bug where we wrote wrong lsn to blob pages
Added separate blob_buffer for fixing bug when updating row that had char/varchar that spanned several pages and also had blobs
Ensure we call _ma_bitmap_flushable() also in case of errors
When doing an update, first delete old entries, then search in bitmap for where to put new information
Info->s -> share
Rowid -> rowid
More DBUG_ASSERT()
storage/maria/ma_blockrec.h:
Added START_EXTENT_BIT and TAIL_PAGE_COUNT_MARKER
Added _ma_bitmap_wait_or_flush() and _ma_bitmap_get_page_bits()

Mark file crashed if applying of index changes fails
Added calls to _ma_fast_unlock_key_del() for protection of shared key_del link.
storage/maria/ma_locking.c:
Added usage of MARIA_FILE_OPEN_COUNT_OFFSET
Added _ma_mark_file_crashed()
storage/maria/ma_loghandler.c:
Fixed bug where we logged uninitialized memory
storage/maria/ma_open.c:
Moved state->changed to be at start of state info on disk to allow one to easly mark files as crashed
storage/maria/ma_page.c:
Disable 'dummy' checksumming of pages as this gave false warnings.
(Need to investigate if this is ever needed)
storage/maria/ma_pagecache.c:
Fixed wrong shift that caused Maria to crash on files > 4G
storage/maria/ma_recovery.c:
In case of errors, start writing on new line if we where in %## %## printing mode (Made errors more readable)
Changed global variable name from warnings -> recovery_warnings
Use MARIA_FILE_CREATE_RENAME_LSN_OFFSET instead of constant
Removed special handling of row position for deleted keys. Keys now always includes row positions
_ma_apply_undo_row_delete() now gets page and row position
Added check that we don't loop forever when handling undo's (in case of bug in undo chain)
Print name of failed REDO/UNDO
storage/maria/ma_recovery.h:
Removed old comment
storage/maria/ma_static.c:
Chaned version number of Maria files to not accidently use old ones (becasue of change of ordering of status variables)
storage/maria/ma_test2.c:
Added option -u to specify number of rows to update
Changed old option -u to be -A, as for ma_test1

First created blob is now of max blob length to ensure we have at least one big blob in the table
storage/maria/ma_test_all.sh:
More tests

Updated results
storage/maria/ma_test_recovery:
Changed tests to use bigger blobs (not just 1K)

Simplify code (changed * to if)
storage/maria/maria_chk.c:
Make output more readable
storage/maria/maria_def.h:

Added variable _dbug_on_ to speed up execution when DBUG is not going to be used
Added --debug-on option to mysqld (to be able to turn of DBUG with --debug-on=0)
Fixed some bugs with 'non_flushable' marking of bitmap pages
Don't use 'non_flushable' marking of bitmap pages for not transactional tables
SHOW CREATE TABLE now shows if table was created with page checksums
Fixed a lot of bugs with BLOB handling in case of update/REDO and UNDO
More tests (especially for blobs) and DBUG_ASSERTS()
More readable output from maria_read_log and maria_chk
Fixed wrong shift that caused Maria to crash on files > 4G
Mark tables as crashed of REDO fails
dbug/dbug.c:
Changed to use my_bool (allowed me to remove some windows specific code)
Added variable _dbug_on_ to speed up execution when DBUG is not going to be used
Removed initialization of variables if not needed
include/my_dbug.h:
Use my_bool for some functions that was defined as BOOLEAN in dbug.c code
Added DBUGGER_ON/DEBUGGER_OFF to speed up execution when DBUG is not used
include/my_global.h:
Define my_bool early
Increase MY_HOW_OFTEN_TO_WRITE as computers are now faster than 10 years ago
mysql-test/mysql-test-run.pl:
Added debug-on=0 to speed up tests
mysql-test/r/maria-recovery.result:
Added new test by Guilhem to test if UNDO_ROW_DELETE preserves rowid
mysql-test/r/maria.result:
Added testing of page checksums
mysql-test/t/crash_commit_before-master.opt:
Added --debug-on as test require DBUG to work
mysql-test/t/maria-recovery-bitmap-master.opt:
Added --debug-on as test require DBUG to work
mysql-test/t/maria-recovery-master.opt:
Added --debug-on as test require DBUG to work
mysql-test/t/maria-recovery.test:
Added new test by Guilhem to test if UNDO_ROW_DELETE preserves rowid
mysql-test/t/maria.test:
Added testing of page checksums
sql/mysqld.cc:
Added --debug-on option (to be able to turn of DBUG with --debug-on=0)
Indentation fixes
Removed end spaces
sql/sql_show.cc:
Allow update_create_info() to inform MySQL if PACK_KEYS, NO_PACK_KEYS, CHECKSUM, PAGE_CHECKSUM or DELAY_KEY_WRITE is used
storage/maria/Makefile.am:
Added ma_test_big.sh
storage/maria/ha_maria.cc:
Store in create_info if page checksums are used (For SHOW CREATE TABLE)
storage/maria/ma_bitmap.c:
Added _ma_bitmap_wait_or_flush() to cause reader of bitmap pages to wait with reading until bitmap is flushed.
Use TAIL_PAGE_COUNT_MARKER for tail pages
Set 'sub_blocks' for and only for the head page or for the first extent of a blob. This is needed for store_extent_info() to be able to set START_EXTENT_BIT's
Don't allocate more than 0x3ffff pages in one extent (We need bit 0x4000 as a START_EXTENT_BIT)
Increase the calculated 'head_length' with the number of bytes used for extents.
Update row->space_on_head_page also in _ma_bitmap_find_new_place()
Make _ma_bitmap_get_page_bits() global. (Needed for UNDO handling)
Changed _ma_bitmap_flushable() to take MARIA_HA instead of MARIA_SHARE.
This was needed to be able to mark the handler if we had a 'non_flushable' call pending or not.
Don't use 'non_flushable' marking of bitmap pages for not transactional tables.
Added BLOCKUSED_USE_ORG_BITMAP handling also for tail pages.
Added more DBUG_ASSERT() to find possible errors in other code
Some code simplications by adding new local variables
storage/maria/ma_blockrec.c:
UNDO of rows now puts back all part of the row on their original pages and positions.
Changed UNDO of DELETE and UNDO of UPDATE to contain information about the original length of data on head block and also extent information
This changes a lot of logic as now an insert of a row on a page may happen to any position (and not just to the first or next free)
Use PAGE_COUNT to mark if an extent is the start of of a blob. (Needed for extent_to_bitmap_blocks())
Added check_directory() for checking that directroy entries are correct.
Added checking of row checksums when reading rows (with EXTRA_DEBUG)
Added make_space_for_directory() and extend_directory() for doing expansion of directory

Added _ma_update_at_original_place() for UNDO of DELETES
Added row->min_length to hold minmum required space needed on head page
Changed find_free_position() to use make_space_for_directory()
Changed make_empty_page() to allow optional creation of directory entry
Changed delete_head_or_tail() and _ma_apply_undo_row_isnert() to not copy pagecache block (speed optimization)
Changed _ma_apply_redo_insert_row_head_or_tail() to be able to insert new row at any position on 'new' page
Changed _ma_apply_undo_row_delete() and _ma_apply_undo_row_update() to put row in it's original position
Ensure allocation of tail blocks are of at least MIN_TAIL_SIZE.
Ensure we store pages in pinned pages even if read failed. (If not we will have pages pinned forever in page cache)
Write original extent information in UNDO entry, not compacted ones (we need position to tails!)
When setting BLOCKUSED_USED, don't clear other bits (we have to preserve BLOCKUSED_USE_ORG_BITMAP)
Fixed som bugs in directory handling
Fixed bug where we wrote wrong lsn to blob pages
Added separate blob_buffer for fixing bug when updating row that had char/varchar that spanned several pages and also had blobs
Ensure we call _ma_bitmap_flushable() also in case of errors
When doing an update, first delete old entries, then search in bitmap for where to put new information
Info->s -> share
Rowid -> rowid
More DBUG_ASSERT()
storage/maria/ma_blockrec.h:
Added START_EXTENT_BIT and TAIL_PAGE_COUNT_MARKER
Added _ma_bitmap_wait_or_flush() and _ma_bitmap_get_page_bits()
storage/maria/ma_check.c:
Don't write extra empty line if there is no deleted blocks
Ignore START_EXTENT_BIT's in page count
Call _ma_fast_unlock_key_del() to free key_del link
storage/maria/ma_close.c:
Ensure that used_key_del is 0. (If not, someone forgot to call _ma_unlock_key_del())
storage/maria/ma_create.c:
Changed constant to macro
storage/maria/ma_delete.c:
For deleted keys, log also position to row
storage/maria/ma_extra.c:
Release blob buffer at maria_reset() if bigger than MARIA_SMALL_BLOB_BUFFER
storage/maria/ma_key_recover.c:
Added bzero() of LSN that confused paged cache in case of uninitialized block
Mark file crashed if applying of index changes fails
Added calls to _ma_fast_unlock_key_del() for protection of shared key_del link.
storage/maria/ma_locking.c:
Added usage of MARIA_FILE_OPEN_COUNT_OFFSET
Added _ma_mark_file_crashed()
storage/maria/ma_loghandler.c:
Fixed bug where we logged uninitialized memory
storage/maria/ma_open.c:
Moved state->changed to be at start of state info on disk to allow one to easly mark files as crashed
storage/maria/ma_page.c:
Disable 'dummy' checksumming of pages as this gave false warnings.
(Need to investigate if this is ever needed)
storage/maria/ma_pagecache.c:
Fixed wrong shift that caused Maria to crash on files > 4G
storage/maria/ma_recovery.c:
In case of errors, start writing on new line if we where in %## %## printing mode (Made errors more readable)
Changed global variable name from warnings -> recovery_warnings
Use MARIA_FILE_CREATE_RENAME_LSN_OFFSET instead of constant
Removed special handling of row position for deleted keys. Keys now always includes row positions
_ma_apply_undo_row_delete() now gets page and row position
Added check that we don't loop forever when handling undo's (in case of bug in undo chain)
Print name of failed REDO/UNDO
storage/maria/ma_recovery.h:
Removed old comment
storage/maria/ma_static.c:
Chaned version number of Maria files to not accidently use old ones (becasue of change of ordering of status variables)
storage/maria/ma_test2.c:
Added option -u to specify number of rows to update
Changed old option -u to be -A, as for ma_test1
Fixed bug in update of rows with blobs (before blobs was always reset to empty on update)
First created blob is now of max blob length to ensure we have at least one big blob in the table
storage/maria/ma_test_all.sh:
More tests
storage/maria/ma_test_recovery.expected:
Updated results
storage/maria/ma_test_recovery:
Changed tests to use bigger blobs (not just 1K)
Added new tests that tests recovery of update with blobs
Removed comparision of .MAD file as it's not guranteed that recovery from scratch gives identical data file as original update
(compact_page() may be called at different times during normal execution and during REDO)
storage/maria/ma_update.c:
Simplify code (changed * to if)
storage/maria/maria_chk.c:
Make output more readable
storage/maria/maria_def.h:
Changed 'changed' to int to prepare for more bits
Added 2 more bytes to status information
Added 'st_mara_row->min_length' for storing min length needed on head page

Fixed bug in update of rows with blobs (before blobs was always reset to empty on update)
storage/maria/ma_test_big.sh:
Testing of insert, update, delete, recovery and undo of rows with blobs
Thanks to the random-ness of ma_test2 this is likely to find most bugs in the row handling

WL#3072 - Maria Recovery
Bulk insert: don't log REDO/UNDO for rows, log one UNDO which will
truncate files; this is an optimization and a bugfix (table was left
half-repaired by crash).
Repair: mark table crashed-on-repair at start, bump skip_redo_lsn at start,
this is easier for recovery (tells it to skip old REDOs or even UNDO
phase) and user (tells it to repair) in case of crash, sync files
in the end.
Recovery skips missing or corrupted table and moves to next record
(in REDO or UNDO phase) to be more robust; warns if happens in UNDO phase.
Bugfix for UNDO_KEY_DELETE_WITH_ROOT (tested in ma_test_recovery)
and maria_enable_indexes().
Create missing bitmaps when needed (there can be more than one to create,
in rare cases), log a record for this.
include/myisamchk.h:
new flag: bulk insert repair mustn't bump create_rename_lsn
mysql-test/lib/mtr_report.pl:
skip normal warning in maria-recovery.test
mysql-test/r/maria-recovery.result:
result: crash before bulk insert is committed, causes proper rollback,
and crash right after OPTIMIZE replaces index file with new index file
leads to table marked corrupted and recovery not failing.
mysql-test/t/maria-recovery.test:
- can't check the table or it would commit the transaction,
but check is made after recovery.
- test of crash before bulk-insert-with-repair is committed
(to see if it is rolled back), and of crash after OPTIMIZE has replaced
index file but not finished all operations (to see if recovery fails -
it used to assert when trying to execute an old REDO on the new
index).
storage/maria/CMakeLists.txt:
new file
storage/maria/Makefile.am:
new file
storage/maria/ha_maria.cc:
- If bulk insert on a transactional table using an index repair:
table is initially empty, so don't log REDO/UNDO for data rows
(optimization), just log an UNDO_BULK_INSERT_WITH_REPAIR
which will, if executed, empty the data and index file. Re-enable
logging in end_bulk_insert().
- write log record for repair operation only after it's fully done,
index sort including (maria_repair*() used to write the log record).
- Adding back file->trn=NULL which was removed by mistake earlier.
storage/maria/ha_maria.h:
new member (see ha_maria.cc)
storage/maria/ma_bitmap.c:
Functions to create missing bitmaps:
- one function which creates missing bitmaps in page cache, except
the missing one with max offset which it does not put into page cache
as it will be modified very soon.
- one function which the one above calls, and creates bitmaps in page
cache
- one function to execute REDO_BITMAP_NEW_PAGE which uses the second
one above.
storage/maria/ma_blockrec.c:
- when logging REDO_DELETE_ALL, not only 'records' and 'checksum'
has to be reset under log's mutex.
- execution of REDO_INSERT_ROW_BLOBS now checks the dirty pages' list
- execution of UNDO_BULK_INSERT_WITH_REPAIR
storage/maria/ma_blockrec.h:
new functions
storage/maria/ma_check.c:
- table-flush-before-repair is moved to a separate function reused
by maria_sort_index(); syncing is added
- maria_repair() is allowed to re-enable logging only if it is the one
which disabled it.
- "_ma_flush_table_files_after_repair" was a bad name, it's not after
repair now, and it should not sync as we do more changes to the files
shortly after (sync is postponed to when writing the log record)
- REDO_REPAIR record should be written only after all repair
operations (in particular after sorting index in ha_mara::repair())
- close to the end of repair by sort, flushing of pages must happen
also in the non-quick case, to prepare for the sync at end.
- in parallel repair, some page flushes are not needed as done
by initialize_variables_for_repair().
storage/maria/ma_create.c:
Update skip_redo_lsn, create_rename_lsn optionally.
storage/maria/ma_delete_all.c:
Need to sync files at end of maria_delete_all_rows(), if transactional.
storage/maria/ma_extra.c:
During repair, we sometimes call _ma_flush_table_files() (via
_ma_flush_table_files_before_swap()) while there is a WRITE_CACHE.
storage/maria/ma_key_recover.c:
- when we see CLR_END for UNDO_BULK_INSERT_WITH_REPAIR, re-enable
indices.
- fixing bug: _ma_apply_undo_key_delete() parsed UNDO_KEY_DELETE_WITH_ROOT
wrongly, leading to recovery failure
storage/maria/ma_key_recover.h:
new prototype
storage/maria/ma_locking.c:
DBUG_VOID_RETURN missing
storage/maria/ma_loghandler.c:
UNDO for bulk insert with repair, and REDO for creating bitmaps.
LOGREC_FIRST_FREE to not have to change the for() every time we
add a new record type.
storage/maria/ma_loghandler.h:
new UNDO and REDO
storage/maria/ma_open.c:
Move share.kfile.file=kfile up a bit, so that _ma_update_state_lsns()
can get its value, this fixes a bug where LSN_REPAIRED_BY_MARIA_CHK
was not corrected on disk by maria_open().
Store skip_redo_lsn in index' header.
maria_enable_indexes() had a bug for BLOCK_RECORD, where an empty
file has one page, not 0 bytes.
storage/maria/ma_recovery.c:
- Skip a corrupted, missing, or repaired-with-maria_chk, table in
recovery: don't fail, just go to next REDO or UNDO; but if an UNDO
is skipped in UNDO phase we issue warnings.
- Skip REDO|UNDO in REDO phase if <skip_redo_lsn.
- If UNDO phase fails, delete transactions to not make trnman
assert.
- Update skip_redo_lsn when playing REDO_CREATE_TABLE
- Don't record UNDOs for old transactions which we don't know (long_trid==0)
- Bugfix for UNDO_KEY_DELETE_WITH_ROOT (see ma_key_recover.c)
- Execution of UNDO_BULK_INSERT_WITH_REPAIR
- Don't try to find a page number in REDO_DELETE_ALL
- Pieces moved to ma_recovery_util.c
storage/maria/ma_rename.c:
name change
storage/maria/ma_static.c:
I modified layout of the index' header (inserted skip_redo_lsn in its middle)
storage/maria/ma_test2.c:
allow breaking the test towards the end, tests execution of
UNDO_KEY_DELETE_WITH_ROOT
storage/maria/ma_test_recovery.expected:
6 as testflag instead of 4
storage/maria/ma_test_recovery:
Increase the amount of rollback work to do when testing recovery
with ma_test2; this reproduces the UNDO_KEY_DELETE_WITH_ROOT bug.
storage/maria/maria_chk.c:
skip_redo_lsn should be updated too, for consistency.
Write a REDO_REPAIR after all operations (including sort-records)
have been done.
No reason to flush blocks after maria_chk_data_link() and
maria_sort_records(), there is maria_close() in the end.
write_log_record() is a function, to not clutter maria_chk().
storage/maria/maria_def.h:
New member skip_redo_lsn in the state, and comments
storage/maria/maria_pack.c:
skip_redo_lsn should be updated too, for consistency
storage/maria/ma_recovery_util.c:
_ma_redo_not_needed_for_page(), defined in ma_recovery.c, is needed
by ma_blockrec.c; this causes link issues, resolved by putting
_ma_redo_not_needed_for_page() into a new file (so that it is not
in the same file as repair-related objects of ma_recovery.c).
storage/maria/ma_recovery_util.h:
new file

WL#3071 Maria checkpoint
Ability for flush_pagecache_blocks() to flush only certain pages of
a file, as instructed by an option "filter" pointer-to-function argument;
Checkpoint and background dirty page flushing use that to flush only
pages which have been dirty for long enough and bitmap pages.
Fix for a bug in flush_cached_blocks() (no idea if it could produce
a bug in real life, but theoretically it is).
Testing checkpoint in ma_test_recovery via ma_test1 and ma_test2.
Background checkpoint & dirty pages flush thread is still disabled
by default in ha_maria.
mysql-test/r/maria.result:
result update
storage/maria/ha_maria.cc:
blank after function comment
storage/maria/ma_checkpoint.c:
Using an enum instead of 0/1/2 (applying Sanja's review comments).
The comment about "this is an horizon" can be removed as Sanja
created translog_next_LSN() which parse_checkpoint_record() uses.
Variables in ma_checkpoint_background() cannot be declared in the
for() as their value must not be reset at each iteration!
storage/maria/ma_pagecache.c:
adding to flush_pagecache_blocks() optional arguments 'filter'
(pointer to function) and 'filter_arg'; if filter!=NULL this function
will be called for each block of the file and will reply if this
block and following ones should be flushed or not (3 possible
replies).
Fixing a bug when flush_cached_blocks() skips a pinned page: it has
to unset PCBLOCK_IN_FLUSH set by flush_pagecache_blocks_int().
storage/maria/ma_pagecache.h:
flush_pagecache_blocks() is changed to take "filter" and "filter_arg"
arguments. "filter", if it is not NULL, may return one value
among enum pagecache_flush_filter_result.
storage/maria/ma_recovery.c:
open_count=0 when closing tables at the end of recovery.
storage/maria/ma_test1.c:
Optional checkpoints (-H#) at various stages (stages similar
to --testflag), for testing of checkpoints.
storage/maria/ma_test2.c:
Optional checkpoints (-H#) at various stages (stages similar
to -t), for testing of checkpoints.
storage/maria/ma_test_recovery.expected:
Result update: the results of the additional test run with -H#
(checkpoints) are added here. They are exactly identical to without
checkpoints except that the index's Root (printed by maria_chk)
is more correct when using checkpoints. This is because checkpoint
flushed the state, so it happens to be correct, while no-checkpoint
does not flush the state, and recovery does not recover indexes
so Root is never fixed. When we recover indices, this will go away.
storage/maria/ma_test_recovery:
We duplicate the loop of tests to add an additional run with
checkpoints at various stages, to see if maria_read_log
uses them fine.

Fixed some bugs with 'non_flushable' marking of bitmap pages
Don't use 'non_flushable' marking of bitmap pages for not transactional tables
SHOW CREATE TABLE now shows if table was created with page checksums
Fixed a lot of bugs with BLOB handling in case of update/REDO and UNDO
More tests (especially for blobs) and DBUG_ASSERTS()
More readable output from maria_read_log and maria_chk
Fixed wrong shift that caused Maria to crash on files > 4G
Mark tables as crashed of REDO fails
dbug/dbug.c:
Changed to use my_bool (allowed me to remove some windows specific code)
Added variable _dbug_on_ to speed up execution when DBUG is not going to be used

Added _ma_bitmap_wait_or_flush() to cause reader of bitmap pages to wait with reading until bitmap is flushed.
Use TAIL_PAGE_COUNT_MARKER for tail pages
Set 'sub_blocks' for and only for the head page or for the first extent of a blob. This is needed for store_extent_info() to be able to set START_EXTENT_BIT's
Don't allocate more than 0x3ffff pages in one extent (We need bit 0x4000 as a START_EXTENT_BIT)
Increase the calculated 'head_length' with the number of bytes used for extents.
Update row->space_on_head_page also in _ma_bitmap_find_new_place()
Make _ma_bitmap_get_page_bits() global. (Needed for UNDO handling)

Some code simplications by adding new local variables
storage/maria/ma_blockrec.c:
UNDO of rows now puts back all part of the row on their original pages and positions.
Changed UNDO of DELETE and UNDO of UPDATE to contain information about the original length of data on head block and also extent information
This changes a lot of logic as now an insert of a row on a page may happen to any position (and not just to the first or next free)
Use PAGE_COUNT to mark if an extent is the start of of a blob. (Needed for extent_to_bitmap_blocks())
Added check_directory() for checking that directroy entries are correct.
Added checking of row checksums when reading rows (with EXTRA_DEBUG)
Added make_space_for_directory() and extend_directory() for doing expansion of directory
Added get_rowpos_in_head_or_tail_page() to be able to store head/tail on original position in UNDO

Added row->min_length to hold minmum required space needed on head page
Changed find_free_position() to use make_space_for_directory()
Changed make_empty_page() to allow optional creation of directory entry
Changed delete_head_or_tail() and _ma_apply_undo_row_isnert() to not copy pagecache block (speed optimization)
Changed _ma_apply_redo_insert_row_head_or_tail() to be able to insert new row at any position on 'new' page
Changed _ma_apply_undo_row_delete() and _ma_apply_undo_row_update() to put row in it's original position
Ensure allocation of tail blocks are of at least MIN_TAIL_SIZE.
Ensure we store pages in pinned pages even if read failed. (If not we will have pages pinned forever in page cache)
Write original extent information in UNDO entry, not compacted ones (we need position to tails!)
When setting BLOCKUSED_USED, don't clear other bits (we have to preserve BLOCKUSED_USE_ORG_BITMAP)
Fixed som bugs in directory handling
Fixed bug where we wrote wrong lsn to blob pages
Added separate blob_buffer for fixing bug when updating row that had char/varchar that spanned several pages and also had blobs
Ensure we call _ma_bitmap_flushable() also in case of errors
When doing an update, first delete old entries, then search in bitmap for where to put new information
Info->s -> share
Rowid -> rowid
More DBUG_ASSERT()
storage/maria/ma_blockrec.h:
Added START_EXTENT_BIT and TAIL_PAGE_COUNT_MARKER
Added _ma_bitmap_wait_or_flush() and _ma_bitmap_get_page_bits()
storage/maria/ma_check.c:
Don't write extra empty line if there is no deleted blocks
Ignore START_EXTENT_BIT's in page count
Call _ma_fast_unlock_key_del() to free key_del link

Mark file crashed if applying of index changes fails
Added calls to _ma_fast_unlock_key_del() for protection of shared key_del link.
storage/maria/ma_locking.c:
Added usage of MARIA_FILE_OPEN_COUNT_OFFSET
Added _ma_mark_file_crashed()
storage/maria/ma_loghandler.c:
Fixed bug where we logged uninitialized memory
storage/maria/ma_open.c:
Moved state->changed to be at start of state info on disk to allow one to easly mark files as crashed
storage/maria/ma_page.c:
Disable 'dummy' checksumming of pages as this gave false warnings.
(Need to investigate if this is ever needed)
storage/maria/ma_pagecache.c:
Fixed wrong shift that caused Maria to crash on files > 4G
storage/maria/ma_recovery.c:
In case of errors, start writing on new line if we where in %## %## printing mode (Made errors more readable)
Changed global variable name from warnings -> recovery_warnings
Use MARIA_FILE_CREATE_RENAME_LSN_OFFSET instead of constant
Removed special handling of row position for deleted keys. Keys now always includes row positions
_ma_apply_undo_row_delete() now gets page and row position
Added check that we don't loop forever when handling undo's (in case of bug in undo chain)
Print name of failed REDO/UNDO
storage/maria/ma_recovery.h:
Removed old comment
storage/maria/ma_static.c:
Chaned version number of Maria files to not accidently use old ones (becasue of change of ordering of status variables)
storage/maria/ma_test2.c:
Added option -u to specify number of rows to update
Changed old option -u to be -A, as for ma_test1
Fixed bug in update of rows with blobs (before blobs was always reset to empty on update)
First created blob is now of max blob length to ensure we have at least one big blob in the table
storage/maria/ma_test_all.sh:
More tests
storage/maria/ma_test_recovery.expected:
Updated results
storage/maria/ma_test_recovery:
Changed tests to use bigger blobs (not just 1K)
Added new tests that tests recovery of update with blobs
Removed comparision of .MAD file as it's not guranteed that recovery from scratch gives identical data file as original update

Simplify code (changed * to if)
storage/maria/maria_chk.c:
Make output more readable

Testing of insert, update, delete, recovery and undo of rows with blobs
Thanks to the random-ness of ma_test2 this is likely to find most bugs in the row handling

Added --debug-on option to mysqld (to be able to turn of DBUG with --debug-on=0)
Fixed some bugs with 'non_flushable' marking of bitmap pages
Don't use 'non_flushable' marking of bitmap pages for not transactional tables
SHOW CREATE TABLE now shows if table was created with page checksums
Fixed a lot of bugs with BLOB handling in case of update/REDO and UNDO
More tests (especially for blobs) and DBUG_ASSERTS()
More readable output from maria_read_log and maria_chk
Fixed wrong shift that caused Maria to crash on files > 4G
Mark tables as crashed of REDO fails
dbug/dbug.c:
Changed to use my_bool (allowed me to remove some windows specific code)

Added _ma_bitmap_wait_or_flush() to cause reader of bitmap pages to wait with reading until bitmap is flushed.
Use TAIL_PAGE_COUNT_MARKER for tail pages
Set 'sub_blocks' for and only for the head page or for the first extent of a blob. This is needed for store_extent_info() to be able to set START_EXTENT_BIT's
Don't allocate more than 0x3ffff pages in one extent (We need bit 0x4000 as a START_EXTENT_BIT)
Increase the calculated 'head_length' with the number of bytes used for extents.
Update row->space_on_head_page also in _ma_bitmap_find_new_place()

Added checking of row checksums when reading rows (with EXTRA_DEBUG)
Added make_space_for_directory() and extend_directory() for doing expansion of directory

Changed _ma_apply_undo_row_delete() and _ma_apply_undo_row_update() to put row in it's original position
Ensure allocation of tail blocks are of at least MIN_TAIL_SIZE.
Ensure we store pages in pinned pages even if read failed. (If not we will have pages pinned forever in page cache)
Write original extent information in UNDO entry, not compacted ones (we need position to tails!)
When setting BLOCKUSED_USED, don't clear other bits (we have to preserve BLOCKUSED_USE_ORG_BITMAP)
Fixed som bugs in directory handling
Fixed bug where we wrote wrong lsn to blob pages
Added separate blob_buffer for fixing bug when updating row that had char/varchar that spanned several pages and also had blobs
Ensure we call _ma_bitmap_flushable() also in case of errors
When doing an update, first delete old entries, then search in bitmap for where to put new information
Info->s -> share
Rowid -> rowid
More DBUG_ASSERT()
storage/maria/ma_blockrec.h:
Added START_EXTENT_BIT and TAIL_PAGE_COUNT_MARKER
Added _ma_bitmap_wait_or_flush() and _ma_bitmap_get_page_bits()

Store in create_info if page checksums are used (For SHOW CREATE TABLE)
storage/maria/ma_bitmap.c:
Added _ma_bitmap_wait_or_flush() to cause reader of bitmap pages to wait with reading until bitmap is flushed.
Use TAIL_PAGE_COUNT_MARKER for tail pages
Set 'sub_blocks' for and only for the head page or for the first extent of a blob. This is needed for store_extent_info() to be able to set START_EXTENT_BIT's
Don't allocate more than 0x3ffff pages in one extent (We need bit 0x4000 as a START_EXTENT_BIT)
Increase the calculated 'head_length' with the number of bytes used for extents.
Update row->space_on_head_page also in _ma_bitmap_find_new_place()
Make _ma_bitmap_get_page_bits() global. (Needed for UNDO handling)

Use PAGE_COUNT to mark if an extent is the start of of a blob. (Needed for extent_to_bitmap_blocks())
Added check_directory() for checking that directroy entries are correct.
Added checking of row checksums when reading rows (with EXTRA_DEBUG)
Added make_space_for_directory() and extend_directory() for doing expansion of directory

Changed _ma_apply_undo_row_delete() and _ma_apply_undo_row_update() to put row in it's original position
Ensure allocation of tail blocks are of at least MIN_TAIL_SIZE.
Ensure we store pages in pinned pages even if read failed. (If not we will have pages pinned forever in page cache)
Write original extent information in UNDO entry, not compacted ones (we need position to tails!)
When setting BLOCKUSED_USED, don't clear other bits (we have to preserve BLOCKUSED_USE_ORG_BITMAP)
Fixed som bugs in directory handling
Fixed bug where we wrote wrong lsn to blob pages
Added separate blob_buffer for fixing bug when updating row that had char/varchar that spanned several pages and also had blobs
Ensure we call _ma_bitmap_flushable() also in case of errors
When doing an update, first delete old entries, then search in bitmap for where to put new information
Info->s -> share
Rowid -> rowid
More DBUG_ASSERT()

storage/maria/ma_locking.c:
Added usage of MARIA_FILE_OPEN_COUNT_OFFSET
Added _ma_mark_file_crashed()

Fixed bug where we logged uninitialized memory
storage/maria/ma_open.c:
Moved state->changed to be at start of state info on disk to allow one to easly mark files as crashed
storage/maria/ma_page.c:
Disable 'dummy' checksumming of pages as this gave false warnings.
(Need to investigate if this is ever needed)
storage/maria/ma_pagecache.c:
Fixed wrong shift that caused Maria to crash on files > 4G
storage/maria/ma_recovery.c:
In case of errors, start writing on new line if we where in %## %## printing mode (Made errors more readable)
Changed global variable name from warnings -> recovery_warnings
Use MARIA_FILE_CREATE_RENAME_LSN_OFFSET instead of constant
Removed special handling of row position for deleted keys. Keys now always includes row positions
_ma_apply_undo_row_delete() now gets page and row position
Added check that we don't loop forever when handling undo's (in case of bug in undo chain)
Print name of failed REDO/UNDO
storage/maria/ma_recovery.h:
Removed old comment
storage/maria/ma_static.c:
Chaned version number of Maria files to not accidently use old ones (becasue of change of ordering of status variables)
storage/maria/ma_test2.c:
Added option -u to specify number of rows to update
Changed old option -u to be -A, as for ma_test1
Fixed bug in update of rows with blobs (before blobs was always reset to empty on update)
First created blob is now of max blob length to ensure we have at least one big blob in the table
storage/maria/ma_test_all.sh:
More tests
storage/maria/ma_test_recovery.expected:
Updated results
storage/maria/ma_test_recovery:
Changed tests to use bigger blobs (not just 1K)
Added new tests that tests recovery of update with blobs
Removed comparision of .MAD file as it's not guranteed that recovery from scratch gives identical data file as original update

Simplify code (changed * to if)
storage/maria/maria_chk.c:
Make output more readable
storage/maria/maria_def.h:

WL#3072 - Maria Recovery
Bulk insert: don't log REDO/UNDO for rows, log one UNDO which will
truncate files; this is an optimization and a bugfix (table was left
half-repaired by crash).
Repair: mark table crashed-on-repair at start, bump skip_redo_lsn at start,
this is easier for recovery (tells it to skip old REDOs or even UNDO
phase) and user (tells it to repair) in case of crash, sync files
in the end.
Recovery skips missing or corrupted table and moves to next record
(in REDO or UNDO phase) to be more robust; warns if happens in UNDO phase.
Bugfix for UNDO_KEY_DELETE_WITH_ROOT (tested in ma_test_recovery)
and maria_enable_indexes().
Create missing bitmaps when needed (there can be more than one to create,
in rare cases), log a record for this.
include/myisamchk.h:
new flag: bulk insert repair mustn't bump create_rename_lsn
mysql-test/lib/mtr_report.pl:
skip normal warning in maria-recovery.test
mysql-test/r/maria-recovery.result:
result: crash before bulk insert is committed, causes proper rollback,
and crash right after OPTIMIZE replaces index file with new index file
leads to table marked corrupted and recovery not failing.
mysql-test/t/maria-recovery.test:
- can't check the table or it would commit the transaction,
but check is made after recovery.
- test of crash before bulk-insert-with-repair is committed
(to see if it is rolled back), and of crash after OPTIMIZE has replaced
index file but not finished all operations (to see if recovery fails -
it used to assert when trying to execute an old REDO on the new
index).
storage/maria/CMakeLists.txt:
new file
storage/maria/Makefile.am:
new file
storage/maria/ha_maria.cc:
- If bulk insert on a transactional table using an index repair:
table is initially empty, so don't log REDO/UNDO for data rows
(optimization), just log an UNDO_BULK_INSERT_WITH_REPAIR
which will, if executed, empty the data and index file. Re-enable
logging in end_bulk_insert().
- write log record for repair operation only after it's fully done,
index sort including (maria_repair*() used to write the log record).
- Adding back file->trn=NULL which was removed by mistake earlier.
storage/maria/ha_maria.h:
new member (see ha_maria.cc)
storage/maria/ma_bitmap.c:
Functions to create missing bitmaps:
- one function which creates missing bitmaps in page cache, except
the missing one with max offset which it does not put into page cache
as it will be modified very soon.
- one function which the one above calls, and creates bitmaps in page
cache
- one function to execute REDO_BITMAP_NEW_PAGE which uses the second
one above.
storage/maria/ma_blockrec.c:
- when logging REDO_DELETE_ALL, not only 'records' and 'checksum'
has to be reset under log's mutex.
- execution of REDO_INSERT_ROW_BLOBS now checks the dirty pages' list
- execution of UNDO_BULK_INSERT_WITH_REPAIR
storage/maria/ma_blockrec.h:
new functions
storage/maria/ma_check.c:
- table-flush-before-repair is moved to a separate function reused
by maria_sort_index(); syncing is added
- maria_repair() is allowed to re-enable logging only if it is the one
which disabled it.
- "_ma_flush_table_files_after_repair" was a bad name, it's not after
repair now, and it should not sync as we do more changes to the files
shortly after (sync is postponed to when writing the log record)
- REDO_REPAIR record should be written only after all repair
operations (in particular after sorting index in ha_mara::repair())
- close to the end of repair by sort, flushing of pages must happen
also in the non-quick case, to prepare for the sync at end.
- in parallel repair, some page flushes are not needed as done
by initialize_variables_for_repair().
storage/maria/ma_create.c:
Update skip_redo_lsn, create_rename_lsn optionally.
storage/maria/ma_delete_all.c:
Need to sync files at end of maria_delete_all_rows(), if transactional.
storage/maria/ma_extra.c:
During repair, we sometimes call _ma_flush_table_files() (via
_ma_flush_table_files_before_swap()) while there is a WRITE_CACHE.
storage/maria/ma_key_recover.c:
- when we see CLR_END for UNDO_BULK_INSERT_WITH_REPAIR, re-enable
indices.
- fixing bug: _ma_apply_undo_key_delete() parsed UNDO_KEY_DELETE_WITH_ROOT
wrongly, leading to recovery failure
storage/maria/ma_key_recover.h:
new prototype
storage/maria/ma_locking.c:
DBUG_VOID_RETURN missing
storage/maria/ma_loghandler.c:
UNDO for bulk insert with repair, and REDO for creating bitmaps.
LOGREC_FIRST_FREE to not have to change the for() every time we
add a new record type.
storage/maria/ma_loghandler.h:
new UNDO and REDO
storage/maria/ma_open.c:
Move share.kfile.file=kfile up a bit, so that _ma_update_state_lsns()
can get its value, this fixes a bug where LSN_REPAIRED_BY_MARIA_CHK
was not corrected on disk by maria_open().
Store skip_redo_lsn in index' header.
maria_enable_indexes() had a bug for BLOCK_RECORD, where an empty
file has one page, not 0 bytes.
storage/maria/ma_recovery.c:
- Skip a corrupted, missing, or repaired-with-maria_chk, table in
recovery: don't fail, just go to next REDO or UNDO; but if an UNDO
is skipped in UNDO phase we issue warnings.
- Skip REDO|UNDO in REDO phase if <skip_redo_lsn.
- If UNDO phase fails, delete transactions to not make trnman
assert.
- Update skip_redo_lsn when playing REDO_CREATE_TABLE
- Don't record UNDOs for old transactions which we don't know (long_trid==0)
- Bugfix for UNDO_KEY_DELETE_WITH_ROOT (see ma_key_recover.c)
- Execution of UNDO_BULK_INSERT_WITH_REPAIR
- Don't try to find a page number in REDO_DELETE_ALL
- Pieces moved to ma_recovery_util.c
storage/maria/ma_rename.c:
name change
storage/maria/ma_static.c:
I modified layout of the index' header (inserted skip_redo_lsn in its middle)
storage/maria/ma_test2.c:
allow breaking the test towards the end, tests execution of
UNDO_KEY_DELETE_WITH_ROOT
storage/maria/ma_test_recovery.expected:
6 as testflag instead of 4
storage/maria/ma_test_recovery:
Increase the amount of rollback work to do when testing recovery
with ma_test2; this reproduces the UNDO_KEY_DELETE_WITH_ROOT bug.
storage/maria/maria_chk.c:
skip_redo_lsn should be updated too, for consistency.
Write a REDO_REPAIR after all operations (including sort-records)
have been done.
No reason to flush blocks after maria_chk_data_link() and
maria_sort_records(), there is maria_close() in the end.
write_log_record() is a function, to not clutter maria_chk().
storage/maria/maria_def.h:
New member skip_redo_lsn in the state, and comments
storage/maria/maria_pack.c:
skip_redo_lsn should be updated too, for consistency
storage/maria/ma_recovery_util.c:
_ma_redo_not_needed_for_page(), defined in ma_recovery.c, is needed
by ma_blockrec.c; this causes link issues, resolved by putting
_ma_redo_not_needed_for_page() into a new file (so that it is not
in the same file as repair-related objects of ma_recovery.c).

WL#3071 Maria checkpoint
Finally this is the real checkpoint code.
It however exhibits unstabilities when a checkpoint runs concurrently
with data-modifying clients (table corruption, transaction log's
assertions) so for now a checkpoint is taken only at startup after
recovery and at shutdown, i.e. not in concurrent situations. Later
we will let it run periodically, as well as flush dirty pages
periodically (almost all needed code is there already, only pagecache
code is written but not committed).
WL#3072 Maria recovery
* replacing UNDO_ROW_PURGE with CLR_END; testing of those CLR_END via
ma_test2 which has INSERTs failing with duplicate keys.
* replaying of REDO_RENAME_TABLE
Now, off to test Recovery in ha_maria :)

storage/maria/Makefile.am:

storage/maria/ha_maria.cc:
When ha_maria starts, do a recovery from last checkpoint.
Take a checkpoint when that recovery has ended and when ha_maria
shuts down cleanly.
storage/maria/ma_blockrec.c:
* even if my_sync() fails we have to my_close() (otherwise we leak
a descriptor)
* UNDO_ROW_PURGE is replaced by a simple CLR_END for UNDO_ROW_INSERT,
as promised in the old comment; it gives us skipping during the
UNDO phase.
storage/maria/ma_check.c:
All REDOs before create_rename_lsn are ignored by Recovery. So
create_rename_lsn must be set only after all data/index has been
flushed and forced to disk. We thus move write_log_record_for_repair()
to after _ma_flush_tables_files_after_repair().
storage/maria/ma_checkpoint.c:
Checkpoint module.
storage/maria/ma_checkpoint.h:
optional argument if caller wants a thread to periodically take
checkpoints and flush dirty pages.
storage/maria/ma_create.c:
* no need to init some vars as the initial bzero(share) takes care of this.
* update to new function's name
* even if we fail in my_sync() we have to my_close()
storage/maria/ma_extra.c:
Checkpoint reads share->last_version under intern_lock, so we make
maria_extra() update it under intern_lock. THR_LOCK_maria still needed
because of _ma_test_if_reopen().
storage/maria/ma_init.c:
destroy checkpoint module when Maria shuts down.
storage/maria/ma_loghandler.c:
* UNDO_ROW_PURGE gone (see ma_blockrec.c)
* we need to remember the LSN of the LOGREC_FILE_ID for a share,
because this LSN is needed into the checkpoint record (Recovery wants
to know the validity domain of an id->name mapping)
* translog_get_horizon_no_lock() needed for Checkpoint
* comment about failing assertion (Sanja knows)
* translog_init_reader_data() thought that translog_read_record_header_scan()
returns 0 in case of error, but 0 just means "0-length header".
* translog_assign_id_to_share() now needs the MARIA_HA because
LOGREC_FILE_ID uses a log-write hook.
* Verify that (de)assignment of share->id happens only under intern_lock,
as Checkpoint reads this id with intern_lock.
* translog_purge() can accept TRANSLOG_ADDRESS, not necessarily
a real LSN.
storage/maria/ma_loghandler.h:
prototype updates
storage/maria/ma_open.c:
no need to initialize "res"
storage/maria/ma_pagecache.c:
When taking a checkpoint, we don't need to know the maximum rec_lsn
of dirty pages; this LSN was intended to be used in the two-checkpoint
rule, but last_checkpoint_lsn is as good.
4 bytes for stored_list_size is enough as PAGECACHE::blocks (number
of blocks which the pagecache can contain) is int.
storage/maria/ma_pagecache.h:
new prototype
storage/maria/ma_recovery.c:
* added replaying of REDO_RENAME_TABLE
* UNDO_ROW_PURGE gone (see ma_blockrec.c), replaced by CLR_END
* Recovery from the last checkpoint record now possible
* In new_table() we skip the table if the id->name mapping is older than
create_rename_lsn (mapping dates from lsn_of_file_id).
* in get_MARIA_HA_from_REDO_record() we skip the record
if the id->name mapping is newer than the record (can happen if processing
a record which is before the checkpoint record).
* parse_checkpoint_record() has to return a LSN, that's what caller expects
storage/maria/ma_rename.c:
new function's name; log end zeroes of tables' names (ease recovery)
storage/maria/ma_test2.c:
* equivalent of ma_test1's --test-undo added (named -u here).
* -t=1 now stops right after creating the table, so that
we can test undoing of INSERTs with duplicate keys (which tests the
CLR_END logged by _ma_write_abort_block_record()).
storage/maria/ma_test_recovery.expected:
Result of testing undoing of INSERTs with duplicate keys; there are
some differences in maria_chk -dvv but they are normal (removing
records does not shrink data/index file, does not put back the
"analyzed, optimized keys"(etc) index state.
storage/maria/ma_test_recovery:
Test undoing of INSERTs with duplicate keys, using ma_test2;
when such INSERT happens, it logs REDO_INSERT, UNDO_INSERT, REDO_DELETE,
CLR_END; we abort after that, and test that CLR_END causes recovery
to jump over UNDO_INSERT.

for this share; needed to know to which LSN domain the mappings
found in the Checkpoint record apply (new mappings should not apply

WL#3071 Maria checkpoint
Finally this is the real checkpoint code.
It however exhibits unstabilities when a checkpoint runs concurrently
with data-modifying clients (table corruption, transaction log's
assertions) so for now a checkpoint is taken only at startup after
recovery and at shutdown, i.e. not in concurrent situations. Later
we will let it run periodically, as well as flush dirty pages
periodically (almost all needed code is there already, only pagecache
code is written but not committed).
WL#3072 Maria recovery
* replacing UNDO_ROW_PURGE with CLR_END; testing of those CLR_END via
ma_test2 which has INSERTs failing with duplicate keys.
* replaying of REDO_RENAME_TABLE
Now, off to test Recovery in ha_maria :)
BitKeeper/deleted/.del-ma_least_recently_dirtied.c:
Delete: storage/maria/ma_least_recently_dirtied.c
BitKeeper/deleted/.del-ma_least_recently_dirtied.h:
Delete: storage/maria/ma_least_recently_dirtied.h
storage/maria/Makefile.am:
compile Checkpoint module
storage/maria/ha_maria.cc:
When ha_maria starts, do a recovery from last checkpoint.
Take a checkpoint when that recovery has ended and when ha_maria
shuts down cleanly.
storage/maria/ma_blockrec.c:
* even if my_sync() fails we have to my_close() (otherwise we leak
a descriptor)
* UNDO_ROW_PURGE is replaced by a simple CLR_END for UNDO_ROW_INSERT,
as promised in the old comment; it gives us skipping during the
UNDO phase.
storage/maria/ma_check.c:
All REDOs before create_rename_lsn are ignored by Recovery. So
create_rename_lsn must be set only after all data/index has been
flushed and forced to disk. We thus move write_log_record_for_repair()
to after _ma_flush_tables_files_after_repair().
storage/maria/ma_checkpoint.c:
Checkpoint module.
storage/maria/ma_checkpoint.h:
optional argument if caller wants a thread to periodically take
checkpoints and flush dirty pages.
storage/maria/ma_create.c:
* no need to init some vars as the initial bzero(share) takes care of this.
* update to new function's name
* even if we fail in my_sync() we have to my_close()
storage/maria/ma_extra.c:
Checkpoint reads share->last_version under intern_lock, so we make
maria_extra() update it under intern_lock. THR_LOCK_maria still needed
because of _ma_test_if_reopen().
storage/maria/ma_init.c:
destroy checkpoint module when Maria shuts down.
storage/maria/ma_loghandler.c:
* UNDO_ROW_PURGE gone (see ma_blockrec.c)
* we need to remember the LSN of the LOGREC_FILE_ID for a share,
because this LSN is needed into the checkpoint record (Recovery wants
to know the validity domain of an id->name mapping)
* translog_get_horizon_no_lock() needed for Checkpoint
* comment about failing assertion (Sanja knows)
* translog_init_reader_data() thought that translog_read_record_header_scan()
returns 0 in case of error, but 0 just means "0-length header".
* translog_assign_id_to_share() now needs the MARIA_HA because
LOGREC_FILE_ID uses a log-write hook.
* Verify that (de)assignment of share->id happens only under intern_lock,
as Checkpoint reads this id with intern_lock.
* translog_purge() can accept TRANSLOG_ADDRESS, not necessarily
a real LSN.
storage/maria/ma_loghandler.h:
prototype updates
storage/maria/ma_open.c:
no need to initialize "res"
storage/maria/ma_pagecache.c:
When taking a checkpoint, we don't need to know the maximum rec_lsn
of dirty pages; this LSN was intended to be used in the two-checkpoint
rule, but last_checkpoint_lsn is as good.
4 bytes for stored_list_size is enough as PAGECACHE::blocks (number
of blocks which the pagecache can contain) is int.
storage/maria/ma_pagecache.h:
new prototype
storage/maria/ma_recovery.c:
* added replaying of REDO_RENAME_TABLE
* UNDO_ROW_PURGE gone (see ma_blockrec.c), replaced by CLR_END
* Recovery from the last checkpoint record now possible
* In new_table() we skip the table if the id->name mapping is older than
create_rename_lsn (mapping dates from lsn_of_file_id).
* in get_MARIA_HA_from_REDO_record() we skip the record
if the id->name mapping is newer than the record (can happen if processing
a record which is before the checkpoint record).
* parse_checkpoint_record() has to return a LSN, that's what caller expects
storage/maria/ma_rename.c:
new function's name; log end zeroes of tables' names (ease recovery)
storage/maria/ma_test2.c:
* equivalent of ma_test1's --test-undo added (named -u here).
* -t=1 now stops right after creating the table, so that
we can test undoing of INSERTs with duplicate keys (which tests the
CLR_END logged by _ma_write_abort_block_record()).
storage/maria/ma_test_recovery.expected:
Result of testing undoing of INSERTs with duplicate keys; there are
some differences in maria_chk -dvv but they are normal (removing
records does not shrink data/index file, does not put back the
"analyzed, optimized keys"(etc) index state.
storage/maria/ma_test_recovery:
Test undoing of INSERTs with duplicate keys, using ma_test2;
when such INSERT happens, it logs REDO_INSERT, UNDO_INSERT, REDO_DELETE,
CLR_END; we abort after that, and test that CLR_END causes recovery
to jump over UNDO_INSERT.
storage/maria/ma_write.c:
comment
storage/maria/maria_chk.c:
comment
storage/maria/maria_def.h:
* a new bit in MARIA_SHARE::in_checkpoint, used to build a list
of unique shares during Checkpoint.
* MARIA_SHARE::lsn_of_file_id added: the LSN of the last LOGREC_FILE_ID
for this share; needed to know to which LSN domain the mappings
found in the Checkpoint record apply (new mappings should not apply
to old REDOs).
storage/maria/trnman.c:
* small changes to how trnman_collect_transactions() fills its buffer;
it also uses a non-dummy lsn_read_non_atomic() found in ma_checkpoint.h
