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
mysql-test/t/maria-recovery.test:
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.

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

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

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
Unit test for recovery: runs ma_test1 and ma_test2 (both only with
INSERTs and DELETEs; UPDATEs disabled as not handled by recovery)
then moves the tables elswhere; recreates tables from the log, and
compares and fails if there is a difference. Passes now.
Most of maria_read_log.c moved to ma_recovery.c, as it will be re-used
for recovery-from-ha_maria.
Bugfixes of applying of REDO_INSERT, REDO_PURGE_ROW.
Applying of REDO_PURGE_BLOCKS, REDO_DELETE_ALL, REDO_DROP_TABLE,
UNDO_ROW_INSERT (in REDO phase only, i.e. just doing records++),
UNDO_ROW_DELETE, UNDO_ROW_PURGE.
Code cleanups.
Monty: please look for "QQ". Sanja: please look for "Sanja".
Future tasks: recovery of the bitmap (easy), recovery of the state
(make it idempotent), more REDOs (Monty to work on
REDO_UPDATE?), UNDO phase...
Pushing this cset as it looks safe, contains test and bugfixes which
will help Monty implement applying of REDO_UPDATE.
sql/handler.cc:
typo
storage/maria/Makefile.am:
Adding ma_test_recovery (which ma_test_all invokes, and which can
also be run alone). Most of maria_read_log.c moved to ma_recovery.c
storage/maria/ha_maria.cc:
comments
storage/maria/ma_bitmap.c:
fixing comments. 2 -> sizeof(maria_bitmap_marker).
Bitmap-related part of _ma_initialize_datafile() moves in bitmap module.
Now putting the "bm" signature when creating the first bitmap page
(it used to happen only at next open, but that
caused an annoying difference when testing Recovery if the original
run didn't open the table, and it looks more
logical like this: it goes to disk only with its signature correct);
see the "QQ" comment towards the _ma_initialize_data_file() call
in ma_create.c for more).
When reading a bitmap page, verify its signature (happens when normally
using the table or when CHECKing it; not when REPAIRing it).
storage/maria/ma_blockrec.c:
* no need to sync the data file if table is not transactional
* Comments, code cleanup (log-related data moved to log-related code
block, int5store->page_store).
* Store the table's short id into LOGREC_UNDO_ROW_PURGE, like we
do for other records (though this record will soon be replaced
with a CLR).
* If "page" is 1 it means the page which extends from byte
page*block_size+1 to (page+1)*block_size (byte number 1 being
the first byte of the file). The last byte of the file is
data_file_length (same convention).
A new page needs to be created if the last byte of the page is
beyond the last byte of the file, i.e.
(page+1)*block_size+1 > data_file_length, so we correct the test
(bug found when testing log applying for ma_test1 -M -T --skip-update).
* update the page's LSN when removing a row from it during
execution of a REDO_PURGE_ROW record (bug found when testing log
applying for ma_test1 -M -T --skip-update).
* applying of REDO_PURGE_BLOCKs (limited to a one-page range for now).
storage/maria/ma_blockrec.h:
new functions. maria_bitmap_marker does not need to be exported.
storage/maria/ma_close.c:
we can always flush the table's state when closing the last instance
of the table. And it is needed for maria_read_log (as it does
not use maria_lock_database()).
storage/maria/ma_control_file.c:
when in Recovery, some assertions should not be used.
storage/maria/ma_control_file.h:
double-inclusion safe
storage/maria/ma_create.c:
during recovery, don't log records. Comments.
Moving the creation of the first bitmap page to ma_bitmap.c
storage/maria/ma_delete_table.c:
during recovery, don't log records. Log the end-zero of the dropped
table's name, so that recovery can use the string in place without
extending it to fit an end zero.
storage/maria/ma_loghandler.c:
* inwrite_rec_hook also needs access to the MARIA_SHARE, like
prewrite_rec_hook. This will be needed to update
share->records_diff (in the upcoming patch "recovery of the state").
* LOG_DESC::record_ends_group changed to an enum.
* LOG_DESC for LOGREC_REDO_PURGE_BLOCKS and LOGREC_UNDO_ROW_PURGE
corrected
* Sanja please see the @todo LOG BUG
* avoiding DBUG_RETURN(func()) as it gives confusing debug traces.
storage/maria/ma_loghandler.h:
- log write hooks called while the log's lock is held (inwrite_rec_hook)
now need the MARIA_SHARE, like prewrite_rec_hook already had
- instead of a bool saying if this record's type ends groups or not,
we refine: it may not end a group, it may end a group, or it may
be a group in itself. Imagine that we had a physical write failure
to a table before we log the UNDO, we still end up in
external_lock(F_UNLCK) and then we log a COMMIT: we don't want
to consider this COMMIT as ending the group of REDOs (don't want
to execute those REDOs during Recovery), that's why we say "COMMIT
is a group in itself, it aborts any previous group". This also
gives one more sanity check in maria_read_log.
storage/maria/ma_recovery.c:
New Recovery code, replacing the old pseudocode.
Most of maria_read_log moved here.
Call-able from ha_maria, but not enabled yet.
Compared to the previous version of maria_read_log, some bugs have
been fixed, debugging output can go to stdout or a disk file (for now
it's useful for me, later it can be changed), execution of
REDO_DROP_TABLE, REDO_DELETE_ALL, REDO_PURGE_BLOCKS has been added. Duplicate code
has been factored into functions. We abort an unfinished group
of records if we see a record which is a group in itself (like COMMIT).
No need for maria_panic() after a bug (which caused tables to not
be closed) was fixed; if there is yet another bug I prefer to see it.
When opening a table for Recovery, set data_file_length
and key_file_length to their real physical value (these are the
easiest state members to restore :). Warn us if the last page
was truncated (but Recovery handles it).
MARIA_SHARE::state::state::records is now partly recovered (not
idempotent, but works if recreating tables from scracth).
When applying a REDO to a page, stamp it with the UNDO's LSN
(current_group_end_lsn), not with the REDO's LSN; it makes
the table more identical to the original table (easier to compare
the two tables in the end).
Big thing missing: some types of REDOs are not handled,
and the UNDO phase does not exist (missing functions to execute UNDOs
to actually rollback). So for now tests are only inserting/deleting
a few 100 rows, closing the table and seeing if the log is applied ok;
it works. UPDATE not handled.
storage/maria/ma_recovery.h:
new functions: ma_recover() for recovery from inside ha_maria;
_ma_apply_log() for maria_read_log (ma_recover() calls _ma_apply_log()).
Btw, we need to not use the word "recover" for REPAIR/maria_chk anymore.
storage/maria/ma_rename.c:
don't write log records during recovery
storage/maria/ma_test2.c:
- fail if maria_info() or other subtests find some wrong information
- new option -g to skip updates.
- init the translog before creating the table, so that log applying
can work.
- in "#if 0" you'll see some fixed bugs (will be removed).
storage/maria/ma_test_all.sh:
cleanup files. Test log applying.
storage/maria/maria_read_log.c:
most of the logic moves to ma_recovery.c to be shared between
maria_read_log and recovery-from-inside-mysqld.
See ma_recovery.c for additional changes made to the moved code.
storage/maria/ma_test_recovery:
unit test for Recovery. Tests insert and delete,
REDO_UPDATE not yet coded.
Script is called from ma_test_all. Can run standalone.

WL#3072 Maria Recovery
- new program maria_read_log to display and apply log records
found in a Maria log (see file's revision comment)
- minor, misc fixes
storage/maria/Makefile.am:
new program maria_read_log
storage/maria/ha_maria.cc:
create control file if missing
storage/maria/ma_blockrec.c:
0 -> LSN_IMPOSSIBLE; comments
storage/maria/ma_checkpoint.h:
preparations for Checkpoint module
storage/maria/ma_close.c:
comment
storage/maria/ma_control_file.c:
renaming constants.
Possibility to say "open control file but don't create it if it's
missing" (used by maria_read_log which does not want to create
anything)
storage/maria/ma_control_file.h:
renaming constants
storage/maria/ma_create.c:
I had duplicated "linkname" and "linkname_ptr", now I see it's not
needed, reverting. Indeed those variables don't contain interesting
information; fixing log record accordingly (the links are in
ci->data/index_file_name). Storing keystart in log record is needed,
to know at which size we must extend the file if we replay
LOGREC_CREATE_TABLE.
storage/maria/ma_loghandler.c:
some structures need to be known to maria_read_log.c, taking
them to ma_loghandler.h
storage/maria/ma_loghandler.h:
we have page_store, adding page_korr.
translog_lock() made public, because Checkpoint will need it (to
write to control file).
Some structures moved from ma_loghandler.c because maria_read_log.c
needs them (needs to know the execute-in-REDO-phase hooks of each
record).
storage/maria/ma_loghandler_lsn.h:
constants defined in ma_control_file.h serve everywhere,
and they relate to LSNs, so putting them in ma_loghandler_lsn.h.
Stronger constraints in LSN_VALID().
storage/maria/ma_pagecache.c:
renaming constants
storage/maria/ma_recovery.h:

storage/maria/ma_test1.c:

storage/maria/ma_test2.c:

comment
storage/maria/maria_read_log.c:
program to read and print log records from a Maria transaction log,
and optionally apply them to tables. Very basic, early version.
Should serve as a base for Recovery's code. Designed to be idempotent.
Create a log by running maria.test, then cd to var/master-data
and run "maria_read_log --only-display" to see info about records;
run "maria_read_log --display-and-apply" to also apply the records
to tables (it's more interesting if you first wipe out the
tables in var/master-data/test, to see how they get re-created).
Only a few records are handled by now: LONG_TRANSACTION_ID,
COMMIT, FILE_ID, REDO_CREATE_TABLE; place is ready for
REDO_INSERT_ROW_HEAD where I could use Monty's help (search for
"Monty" in the file). Note: changes to the index pages, index's header
and bitmap pages are not properly logged yet, so don't expect
the program to work with that.

WL#3234 Maria control file manager.
Fitting ma_control_file_test into the mytap unittest framework:
new directories:
- unittest/storage/ for unit tests of any storage engine
- unittest/storage/maria for ... Maria, containing ma_control_file-t.
Later, older tests like ma_test*, ma_test_all (but which is Unix
dependent in its current form) could move here too.
The plugins macro enable building of unittest/storage/X for any
enabled engine X which has such a directory.
If Falcon wants to have unit tests there too, I may have to merge
this patch into 5.x one day.
config/ac-macros/plugins.m4:
If a storage engine has a directory in unittest/storage, build this
directory.
configure.in:
build storage engines' unit tests.
storage/maria/Makefile.am:
ma_control_file_test moves to unittest/storage/maria
storage/maria/ma_control_file.c:
more error codes when opening the control file fails.
ma_control_file_end() may now return an error if my_close() failed.
storage/maria/ma_control_file.h:
more error codes when opening the control file fails.
unittest/Makefile.am:
adding unit tests for storage engines.
Note that unit.pl simply recurses into "storage", so if a unit test for
storage engine X has been built previously, and now you re-configure
(without making clean) to disable this engine, then the unit test of
X will not be rebuilt but will still be present in storage/X, so will
be run.
unittest/storage/maria/ma_control_file-t.c:
Making the test fit the mytap framework (return all the way up
the stack instead of assert(); use the mytap functions plan(), ok() etc).
Adding test of file too short/long.
unittest/storage/maria/Makefile.am:
a_control_file-t is added to the Maria unit tests.
Later, older tests (ma_test1 etc) could also move here.
unittest/storage/Makefile.am:
New BitKeeper file ``unittest/storage/Makefile.am''

- WL#3239 "log CREATE TABLE in Maria"
- WL#3240 "log DROP TABLE in Maria"
- similarly, log RENAME TABLE, REPAIR/OPTIMIZE TABLE, and
DELETE no_WHERE_clause (== the DELETE which just truncates the files)
- create_rename_lsn added to MARIA_SHARE's state
- all these operations (except DROP TABLE) also update the table's
create_rename_lsn, which is needed for the correctness of
Recovery (see function comment of _ma_repair_write_log_record()
in ma_check.c)
- write a COMMIT record when transaction commits.
- don't log REDOs/UNDOs if this is an internal temporary table
like inside ALTER TABLE (I expect this to be a big win). There was
already no logging for user-created "CREATE TEMPORARY" tables.
- don't fsync files/directories if the table is not transactional
- in translog_write_record(), autogenerate a 2-byte-id for the table
and log the "id->name" pair (LOGREC_FILE_ID); log
LOGREC_LONG_TRANSACTION_ID; automatically store
the table's 2-byte-id in any log record.
- preparations for Checkpoint: translog_get_horizon(); pausing Checkpoint
when some dirty pages are unknown; capturing trn->rec_lsn,
trn->first_undo_lsn for Checkpoint and log's low-water-mark computing.
- assertions, comments.
storage/maria/Makefile.am:
more files to build
storage/maria/ha_maria.cc:
- logging a REPAIR log record if REPAIR/OPTIMIZE was successful.
- ha_maria::data_file_type does not have to be set in every info()
call, just do it once in open().
- if caller said that transactionality can be disabled (like if
caller is ALTER TABLE) i.e. thd->transaction.on==FALSE, then we
temporarily disable transactionality of the table in external_lock();
that will ensure that no REDOs/UNDOs are logged for this possibly
massive write operation (they are not needed, as if any write fails,
the table will be dropped). We re-enable in external_lock(F_UNLCK),
which in ALTER TABLE happens before the tmp table replaces the original
one (which is good, as thus the final table will have a REDO RENAME
and a correct create_rename_lsn).
- when we commit we also have to write a log record, so
trnman_commit_trn() calls become ma_commit() calls
- at end of engine's initialization, we are potentially entering a
multi-threaded dangerous world (clients are going to be accepted)
and so some assertions of mutex-owning become enforceable, for that
we set maria_multi_threaded=TRUE (see ma_control_file.c)
storage/maria/ha_maria.h:
new member ha_maria::save_transactional (see also ha_maria.cc)
storage/maria/ma_blockrec.c:
- fixing comments according to discussion with Monty
- if a table is transactional but temporarily non-transactional
(like in ALTER TABLE), we need to give a sensible LSN to the pages
(and, if we give 0, pagecache asserts).
- translog_write_record() now takes care of storing the share's
2-byte-id in the log record
storage/maria/ma_blockrec.h:
fixing comment according to discussion with Monty
storage/maria/ma_check.c:
When REPAIR/OPTIMIZE modify the data/index file, if this is a
transactional table, they must sync it; if they remove files or rename
files, they must sync the directory, so that everything is durable.
This is just applying to REPAIR/OPTIMIZE the logic already implemented
in CREATE/DROP/RENAME a few months ago.
Adding a function to write a LOGREC_REPAIR_TABLE at end of
REPAIR/OPTIMIZE (called only by ha_maria, not by maria_chk), and
to update the table's create_rename_lsn.
storage/maria/ma_close.c:
fix for a future bug
storage/maria/ma_control_file.c:
ensuring that if Maria is running in multi-threaded mode, anybody
wanting to write to the control file and update
last_checkpoint_lsn/last_logno owns the log's lock.
storage/maria/ma_control_file.h:
see ma_control_file.c
storage/maria/ma_create.c:
when creating a table:
- sync it and its directory only if this is a transactional table
and there is a log (no point in syncing in maria_chk)
- decouple the two uses of linkname/linkname_ptr (for index file and
for data file) into more variables, as we need to know all links
until the moment we write the LOGREC_CREATE_TABLE.
- set share.data_file_type early so that _ma_initialize_data_file()
knows it (Monty's bugfix so that a table always has at least a bitmap
page when it is created; so data-file is not 0 bytes anymore).
- log a LOGREC_CREATE_TABLE; it contains the bytes which we have
just written to the index file's header. Update table's
create_rename_lsn.
- syncing of kfile had been bugified in a previous merge, correcting
- syncing of dfile is now needed as it's not empty anymore
- in _ma_initialize_data_file(), use share's block_size and not the
global one. This is a gratuitous change, both variables are equal,
just that I find it more future-proof to use share-bound variable
rather than global one.
storage/maria/ma_delete_all.c:
log a LOGREC_DELETE_ALL record when doing ma_delete_all_rows();
update create_rename_lsn then.
storage/maria/ma_delete_table.c:
- logging LOGREC_DROP_TABLE; knowing if this is needed, requires
knowing if the table is transactional, which requires opening the
table.
- we need to sync directories only if the table is transactional
storage/maria/ma_extra.c:
questions
storage/maria/ma_init.c:
when maria_end() is called, engine is not multithreaded
storage/maria/ma_loghandler.c:
- translog_inited has to be visible to ma_create() (see how it is used
in ma_create())
- checkpoint record will be a single record, not three
- no REDO for TRUNCATE (TRUNCATE calls ma_create() internally so will
log a REDO_CREATE)
- adding REDO for DELETE no_WHERE_clause (fast DELETE of all rows by
truncating the files), REPAIR.
- MY_WAIT_IF_FULL to wait&retry if a log write hits a full disk
- in translog_write_record(), if MARIA_SHARE does not yet have a
2-byte-id, generate one for it and log LOGREC_FILE_ID; automatically
store this short id into log records.
- in translog_write_record(), if transaction has not logged its
long trid, log LOGREC_LONG_TRANSACTION_ID.
- For Checkpoint, we need to know the current end-of-log: adding
translog_get_horizon().
- For Control File, adding an assertion that the thread owns the
log's lock (control file is protected by this lock)
storage/maria/ma_loghandler.h:
Changes in log records (see ma_loghandler.c).
new prototypes, new functions.
storage/maria/ma_loghandler_lsn.h:
adding a type LSN_WITH_FLAGS especially for TRN::first_undo_lsn,
where the most significant byte is used for flags.
storage/maria/ma_open.c:
storing the create_rename_lsn in the index file's header (in the
state, precisely) and retrieving it from there.
storage/maria/ma_pagecache.c:
- my set_if_bigger was wrong, correcting it
- if the first_in_switch list is not empty, it means that
changed_blocks misses some dirty pages, so Checkpoint cannot run and
needs to wait. A variable missing_blocks_in_changed_list is added to
tell that (should it be named missing_blocks_in_changed_blocks?)
- pagecache_collect_changed_blocks_with_lsn() now also tells the
minimum rec_lsn (needed for low-water mark computation).
storage/maria/ma_pagecache.h:
see ma_pagecache.c
storage/maria/ma_panic.c:
comment
storage/maria/ma_range.c:
comment
storage/maria/ma_rename.c:
- logging LOGREC_RENAME_TABLE; knowing if this is needed, requires
knowing if the table is transactional, which requires opening the
table.
- update create_rename_lsn
- we need to sync directories only if the table is transactional
storage/maria/ma_static.c:
comment
storage/maria/ma_test_all.sh:
- tip for Valgrind-ing ma_test_all
- do "export maria_path=somepath" before calling ma_test_all,
if you want to run ma_test_all out of storage/maria (useful
to have parallel runs, like one normal and one Valgrind, they
must not use the same tables so need to run in different directories)
storage/maria/maria_def.h:
- state now contains, in memory and on disk, the create_rename_lsn
- share now contains a 2-byte-id
storage/maria/trnman.c:
preparations for Checkpoint: capture trn->rec_lsn, trn->first_undo_lsn;
minimum first_undo_lsn needed to know log's low-water-mark
storage/maria/trnman.h:
using most significant byte of first_undo_lsn to hold miscellaneous
flags, for now TRANSACTION_LOGGED_LONG_ID.
dummy_transaction_object is already declared in ma_static.c.
storage/maria/trnman_public.h:
dummy_transaction_object was declared in all files including
trnman_public.h, while in fact it's a single object.
new prototype
storage/maria/unittest/ma_test_loghandler-t.c:
update for new prototype
storage/maria/unittest/ma_test_loghandler_multigroup-t.c:
update for new prototype
storage/maria/unittest/ma_test_loghandler_multithread-t.c:
update for new prototype
storage/maria/unittest/ma_test_loghandler_pagecache-t.c:
update for new prototype
storage/maria/ma_commit.c:
function which wraps:
- writing a LOGREC_COMMIT record (==commit on disk)
- calling trnman_commit_trn() (=commit in memory)
storage/maria/ma_commit.h:
new header file
.tree-is-private:
this file is now needed to keep our tree private (don't push it
to public trees). When 5.1 is merged into mysql-maria, we can abandon
our maria-specific post-commit trigger; .tree_is_private will take
care of keeping commit mails private. Don't push this file to public
trees.

storage/maria/Makefile.am:
Added ma_state.c and ma_state.h
storage/maria/ha_maria.cc:
Versioning of count(*) and checksum
- share->state.state is now assumed to be correct, not handler->state
- Call _ma_setup_live_state() in external lock to get count(*)/checksum versioning. In case of
not versioned and not concurrent insertable table, file->s->state.state contains the correct state information
Other things:
- file->s -> share
- Added DBUG_ASSERT() for unlikely case
- Optimized end_bulk_insert() to not write anything if table is going to be deleted (as in failed alter table)
- Indentation changes in external_lock becasue of removed 'goto' caused a big conflict even if very little was changed
storage/maria/ha_maria.h:
New argument to end_bulk_insert()
storage/maria/ma_blockrec.c:
Update for versioning of count(*) and checksum

Call _ma_reset_state() to update share->state_history at end of repair
storage/maria/ma_checkpoint.c:
Call _ma_remove_not_visible_states() on checkpoint to clean up not visible state history from tables
storage/maria/ma_close.c:
Remember state history for running transaction even if table is closed
storage/maria/ma_commit.c:
Ensure we always call trnman_commit_trn() even if other calls fails. If we don't do that, the translog and state structures will not be freed
storage/maria/ma_delete.c:
Versioning of count(*) and checksum:
- Always update info->state->checksum and info->state->records
storage/maria/ma_delete_all.c:
Versioning of count(*) and checksum:
- Ensure that share->state.state is updated, as here is where we store the primary information
storage/maria/ma_dynrec.c:
Use lock_key_trees instead of concurrent_insert to check if trees should be locked.
This allows us to lock trees both for concurrent_insert and for index versioning.
storage/maria/ma_extra.c:
Versioning of count(*) and checksum:
- Use share->state.state instead of info->state
- share->concurrent_insert -> share->non_transactional_concurrent_insert
- Don't update share->state.state from info->state if transactional table
Optimization:
- Don't flush io_cache or bitmap if we are using FLUSH_IGNORE_CHANGED

Get most state information from current state
storage/maria/ma_init.c:
Add hash table and free function to store states for closed tables
Install hook for transaction commit/rollback to update history state

storage/maria/ma_locking.c:
Versioning of count(*) and checksum:
- Call virtual functions (if exists) to restore/update status
- Move _ma_xxx_status() functions to ma_state.c
info->s -> share
storage/maria/ma_open.c:
Versioning of count(*) and checksum:
- For not transactional tables, set info->state to point to new allocated state structure.
- Initialize new info->state_start variable that points to state at start of transaction
- Copy old history states from hash table (maria_stored_states) first time the table is opened
- Split flag share->concurrent_insert to non_transactional_concurrent_insert & lock_key_tree
- For now, only enable versioning of tables without keys (to be fixed in soon!)
- Added new virtual function to restore status in maria_lock_database)
More DBUG

Move MARIA_STATUS_INFO to ma_state.h
Changes to MARIA_SHARE:
- Added state_history to store count(*)/checksum states
- Added in_trans as counter if table is used by running transactions
- Split concurrent_insert into lock_key_trees and on_transactional_concurrent_insert.
- Added virtual function lock_restore_status
Changes to MARIA_HA:

Added ma_state.c and ma_state.h
storage/maria/ha_maria.cc:
Versioning of count(*) and checksum
- share->state.state is now assumed to be correct, not handler->state
- Call _ma_setup_live_state() in external lock to get count(*)/checksum versioning. In case of
not versioned and not concurrent insertable table, file->s->state.state contains the correct state information
Other things:
- file->s -> share
- Added DBUG_ASSERT() for unlikely case
- Optimized end_bulk_insert() to not write anything if table is going to be deleted (as in failed alter table)
- Indentation changes in external_lock becasue of removed 'goto' caused a big conflict even if very little was changed

storage/maria/ma_close.c:
Remember state history for running transaction even if table is closed
storage/maria/ma_commit.c:
Ensure we always call trnman_commit_trn() even if other calls fails. If we don't do that, the translog and state structures will not be freed
storage/maria/ma_delete.c:
Versioning of count(*) and checksum:
- Always update info->state->checksum and info->state->records
storage/maria/ma_delete_all.c:
Versioning of count(*) and checksum:
- Ensure that share->state.state is updated, as here is where we store the primary information

Use lock_key_trees instead of concurrent_insert to check if trees should be locked.
This allows us to lock trees both for concurrent_insert and for index versioning.
storage/maria/ma_extra.c:
Versioning of count(*) and checksum:
- Use share->state.state instead of info->state
- share->concurrent_insert -> share->non_transactional_concurrent_insert
- Don't update share->state.state from info->state if transactional table
Optimization:
- Don't flush io_cache or bitmap if we are using FLUSH_IGNORE_CHANGED

Get most state information from current state
storage/maria/ma_init.c:
Add hash table and free function to store states for closed tables
Install hook for transaction commit/rollback to update history state
storage/maria/ma_key_recover.c:
Versioning of count(*) and checksum:

storage/maria/ma_locking.c:
Versioning of count(*) and checksum:
- Call virtual functions (if exists) to restore/update status
- Move _ma_xxx_status() functions to ma_state.c
info->s -> share
storage/maria/ma_open.c:
Versioning of count(*) and checksum:
- For not transactional tables, set info->state to point to new allocated state structure.
- Initialize new info->state_start variable that points to state at start of transaction
- Copy old history states from hash table (maria_stored_states) first time the table is opened
- Split flag share->concurrent_insert to non_transactional_concurrent_insert & lock_key_tree
- For now, only enable versioning of tables without keys (to be fixed in soon!)
- Added new virtual function to restore status in maria_lock_database)
More DBUG

- WL#3239 "log CREATE TABLE in Maria"
- WL#3240 "log DROP TABLE in Maria"
- similarly, log RENAME TABLE, REPAIR/OPTIMIZE TABLE, and
DELETE no_WHERE_clause (== the DELETE which just truncates the files)
- create_rename_lsn added to MARIA_SHARE's state
- all these operations (except DROP TABLE) also update the table's
create_rename_lsn, which is needed for the correctness of
Recovery (see function comment of _ma_repair_write_log_record()
in ma_check.c)
- write a COMMIT record when transaction commits.
- don't log REDOs/UNDOs if this is an internal temporary table
like inside ALTER TABLE (I expect this to be a big win). There was
already no logging for user-created "CREATE TEMPORARY" tables.
- don't fsync files/directories if the table is not transactional
- in translog_write_record(), autogenerate a 2-byte-id for the table
and log the "id->name" pair (LOGREC_FILE_ID); log
LOGREC_LONG_TRANSACTION_ID; automatically store
the table's 2-byte-id in any log record.
- preparations for Checkpoint: translog_get_horizon(); pausing Checkpoint
when some dirty pages are unknown; capturing trn->rec_lsn,
trn->first_undo_lsn for Checkpoint and log's low-water-mark computing.
- assertions, comments.
storage/maria/Makefile.am:
more files to build
storage/maria/ha_maria.cc:
- logging a REPAIR log record if REPAIR/OPTIMIZE was successful.
- ha_maria::data_file_type does not have to be set in every info()
call, just do it once in open().
- if caller said that transactionality can be disabled (like if
caller is ALTER TABLE) i.e. thd->transaction.on==FALSE, then we
temporarily disable transactionality of the table in external_lock();
that will ensure that no REDOs/UNDOs are logged for this possibly
massive write operation (they are not needed, as if any write fails,
the table will be dropped). We re-enable in external_lock(F_UNLCK),
which in ALTER TABLE happens before the tmp table replaces the original
one (which is good, as thus the final table will have a REDO RENAME
and a correct create_rename_lsn).
- when we commit we also have to write a log record, so
trnman_commit_trn() calls become ma_commit() calls
- at end of engine's initialization, we are potentially entering a
multi-threaded dangerous world (clients are going to be accepted)
and so some assertions of mutex-owning become enforceable, for that
we set maria_multi_threaded=TRUE (see ma_control_file.c)
storage/maria/ha_maria.h:
new member ha_maria::save_transactional (see also ha_maria.cc)
storage/maria/ma_blockrec.c:
- fixing comments according to discussion with Monty
- if a table is transactional but temporarily non-transactional
(like in ALTER TABLE), we need to give a sensible LSN to the pages
(and, if we give 0, pagecache asserts).
- translog_write_record() now takes care of storing the share's
2-byte-id in the log record
storage/maria/ma_blockrec.h:
fixing comment according to discussion with Monty
storage/maria/ma_check.c:
When REPAIR/OPTIMIZE modify the data/index file, if this is a
transactional table, they must sync it; if they remove files or rename
files, they must sync the directory, so that everything is durable.
This is just applying to REPAIR/OPTIMIZE the logic already implemented
in CREATE/DROP/RENAME a few months ago.
Adding a function to write a LOGREC_REPAIR_TABLE at end of
REPAIR/OPTIMIZE (called only by ha_maria, not by maria_chk), and
to update the table's create_rename_lsn.
storage/maria/ma_close.c:
fix for a future bug
storage/maria/ma_control_file.c:
ensuring that if Maria is running in multi-threaded mode, anybody
wanting to write to the control file and update
last_checkpoint_lsn/last_logno owns the log's lock.
storage/maria/ma_control_file.h:
see ma_control_file.c
storage/maria/ma_create.c:
when creating a table:
- sync it and its directory only if this is a transactional table
and there is a log (no point in syncing in maria_chk)
- decouple the two uses of linkname/linkname_ptr (for index file and
for data file) into more variables, as we need to know all links
until the moment we write the LOGREC_CREATE_TABLE.
- set share.data_file_type early so that _ma_initialize_data_file()
knows it (Monty's bugfix so that a table always has at least a bitmap
page when it is created; so data-file is not 0 bytes anymore).
- log a LOGREC_CREATE_TABLE; it contains the bytes which we have
just written to the index file's header. Update table's
create_rename_lsn.
- syncing of kfile had been bugified in a previous merge, correcting
- syncing of dfile is now needed as it's not empty anymore
- in _ma_initialize_data_file(), use share's block_size and not the
global one. This is a gratuitous change, both variables are equal,
just that I find it more future-proof to use share-bound variable
rather than global one.
storage/maria/ma_delete_all.c:
log a LOGREC_DELETE_ALL record when doing ma_delete_all_rows();
update create_rename_lsn then.
storage/maria/ma_delete_table.c:
- logging LOGREC_DROP_TABLE; knowing if this is needed, requires
knowing if the table is transactional, which requires opening the
table.
- we need to sync directories only if the table is transactional
storage/maria/ma_extra.c:
questions
storage/maria/ma_init.c:
when maria_end() is called, engine is not multithreaded
storage/maria/ma_loghandler.c:
- translog_inited has to be visible to ma_create() (see how it is used
in ma_create())
- checkpoint record will be a single record, not three
- no REDO for TRUNCATE (TRUNCATE calls ma_create() internally so will
log a REDO_CREATE)
- adding REDO for DELETE no_WHERE_clause (fast DELETE of all rows by
truncating the files), REPAIR.
- MY_WAIT_IF_FULL to wait&retry if a log write hits a full disk
- in translog_write_record(), if MARIA_SHARE does not yet have a
2-byte-id, generate one for it and log LOGREC_FILE_ID; automatically
store this short id into log records.
- in translog_write_record(), if transaction has not logged its
long trid, log LOGREC_LONG_TRANSACTION_ID.
- For Checkpoint, we need to know the current end-of-log: adding
translog_get_horizon().
- For Control File, adding an assertion that the thread owns the
log's lock (control file is protected by this lock)
storage/maria/ma_loghandler.h:
Changes in log records (see ma_loghandler.c).
new prototypes, new functions.
storage/maria/ma_loghandler_lsn.h:
adding a type LSN_WITH_FLAGS especially for TRN::first_undo_lsn,
where the most significant byte is used for flags.
storage/maria/ma_open.c:
storing the create_rename_lsn in the index file's header (in the
state, precisely) and retrieving it from there.
storage/maria/ma_pagecache.c:
- my set_if_bigger was wrong, correcting it
- if the first_in_switch list is not empty, it means that
changed_blocks misses some dirty pages, so Checkpoint cannot run and
needs to wait. A variable missing_blocks_in_changed_list is added to
tell that (should it be named missing_blocks_in_changed_blocks?)
- pagecache_collect_changed_blocks_with_lsn() now also tells the
minimum rec_lsn (needed for low-water mark computation).
storage/maria/ma_pagecache.h:
see ma_pagecache.c
storage/maria/ma_panic.c:
comment
storage/maria/ma_range.c:
comment
storage/maria/ma_rename.c:
- logging LOGREC_RENAME_TABLE; knowing if this is needed, requires
knowing if the table is transactional, which requires opening the
table.
- update create_rename_lsn
- we need to sync directories only if the table is transactional
storage/maria/ma_static.c:
comment
storage/maria/ma_test_all.sh:
- tip for Valgrind-ing ma_test_all
- do "export maria_path=somepath" before calling ma_test_all,
if you want to run ma_test_all out of storage/maria (useful
to have parallel runs, like one normal and one Valgrind, they
must not use the same tables so need to run in different directories)
storage/maria/maria_def.h:
- state now contains, in memory and on disk, the create_rename_lsn
- share now contains a 2-byte-id
storage/maria/trnman.c:
preparations for Checkpoint: capture trn->rec_lsn, trn->first_undo_lsn;
minimum first_undo_lsn needed to know log's low-water-mark
storage/maria/trnman.h:
using most significant byte of first_undo_lsn to hold miscellaneous
flags, for now TRANSACTION_LOGGED_LONG_ID.
dummy_transaction_object is already declared in ma_static.c.
storage/maria/trnman_public.h:
dummy_transaction_object was declared in all files including
trnman_public.h, while in fact it's a single object.
new prototype
storage/maria/unittest/ma_test_loghandler-t.c:
update for new prototype
storage/maria/unittest/ma_test_loghandler_multigroup-t.c:

storage/maria/ma_commit.c:
function which wraps:
- writing a LOGREC_COMMIT record (==commit on disk)
- calling trnman_commit_trn() (=commit in memory)
storage/maria/ma_commit.h:
new header file
.tree-is-private:
this file is now needed to keep our tree private (don't push it
to public trees). When 5.1 is merged into mysql-maria, we can abandon
our maria-specific post-commit trigger; .tree_is_private will take
care of keeping commit mails private. Don't push this file to public
trees.

Added versioning of Maria index
Store max_trid in index file as state.create_trid. This is used to pack all transids in the index pages relative to max possible transid for file.
Enable versioning for transactional tables with index. Tables with an auto-increment key, rtree or fulltext keys are not versioned.
Changed info->lastkey to type MARIA_KEY. Removed info->lastkey_length as this is now part of info->lastkey
Renamed old info->lastkey to info->lastkey_buff
Use exact key lenghts for keys, not USE_WHOLE_KEY
For partial key searches, use SEARCH_PART_KEY
When searching to insert new key on page, use SEARCH_INSERT to mark that key has rowid
Changes done in a lot of files:
- Modified functions to use MARIA_KEY instead of key pointer and key length
- Use keyinfo->root_lock instead of share->key_root_lock[keynr]
- Simplify code by using local variable keyinfo instead if share->keyinfo[i]
- Added #fdef EXTERNAL_LOCKING around removed state elements
- HA_MAX_KEY_BUFF -> MARIA_MAX_KEY_BUFF (to reserve space for transid)
- Changed type of 'nextflag' to uint32 to ensure all SEARCH_xxx flags fits into it

mysys/my_handler.c:
Updated function comment to reflect old code
Changed nextflag to be uint32 to ensure we can have flags > 16 bit
Changed checking if we are in insert with NULL keys as next_flag can now include additional bits that have to be ignored.
Added SEARCH_INSERT flag to be used when inserting new keys in btree. This flag tells us the that the keys includes row position and it's thus safe to remove SEARCH_FIND

At table unlock, set file->state to point to live state. (Needed for information schema to pick up right number of rows)
In ha_maria::implicit_commit() move all locked (ie open) tables to new transaction. This is needed to ensure ha_maria->info doesn't point to a deleted history event.
Disable concurrent inserts for insert ... select and table changes with subqueries if statement based replication as this would cause wrong results on slave
storage/maria/ma_blockrec.c:
Updated comment
