comment
storage/maria/ha_maria.cc:
_ma_reenable_logging_for_table() now includes file->trn=0.
At the end of repair() we don't need to re-enable logging, it is
done already by caller (like copy_data_between_tables()); it sounds
strange that this function could decide to re-enable, it should be
up to caller who knows what other operations it plans. Removing this
line led to assertion failure in maria_lock_database(F_UNLCK), fixed
by removing the assertion: maria_lock_database()
is here called in a context where F_UNLCK does not make the
table visible to others so assertion is excessive, and external_lock()
is already designed to honour the asserted condition.
Ability to crash at the end of bulk insert when indices
have been enabled.
storage/maria/ma_bitmap.c:
Better use pagecache_file_init() than set pagecache callbacks directly;
and a new function to set those callbacks for bitmap so that we can
reuse it.
_ma_bitmap_get_log_address() is a pagecache get_log_address callback
which causes the whole log to be flushed when a bitmap page
is flushed by the page cache. This was required by WAL.
storage/maria/ma_blockrec.c:
get_log_address pagecache callback for data (non bitmap) pages:
just reads the LSN from the page's content, like was hard-coded
before in ma_pagecache.c.
storage/maria/ma_blockrec.h:
functions which need to be exported
storage/maria/ma_check.c:
create_new_data_handle() can be static.
Ability to crash after rebuilding the index in OPTIMIZE,
in REPAIR. my_lock() implemented already.
storage/maria/ma_checkpoint.c:
As MARIA_SHARE* is now accessible to pagecache_collect_changed_blocks_LSN(),
we don't need to store kfile/dfile descriptors in checkpoint record,
2-byte-id of the table plus one byte to say if this is data or index
file is enough. So we go from 4+4 bytes per table down to 2+1.
storage/maria/ma_commit.c:
removing duplicate functions (see _ma_tmp_disable_logging_for_table())

storage/maria/ma_key_recover.c:
comment
storage/maria/ma_locking.c:
Sometimes other code does funny things with maria_lock_database(),
like ha_maria::repair() calling it at start and end without going
through ha_maria::external_lock(). So it happens that maria_lock_database()
is called with now_transactional!=born_transactional.
storage/maria/ma_loghandler.c:
update to new prototype
storage/maria/ma_open.c:
set_data|index_pagecache_callbacks() need to be exported as
they are now called when disabling/enabling transactionality.
storage/maria/ma_pagecache.c:
Removing PAGE_LSN_OFFSET, as much of the code relies on it being
0 anyway (let's not give impression we can just change this constant).
When flushing a page to disk, call the get_log_address callback to
know up to which LSN the log should be flushed.
As we now can access MARIA_SHARE* we can know share->id and store
it into the checkpoint record; we thus go from 4 bytes per dirty page
to 2+1.
storage/maria/ma_pagecache.h:
get_log_address callback
storage/maria/ma_panic.c:
No reason to reset pagecache callbacks in HA_PANIC_READ:
all we do is reopen files if they were closed; callbacks should
be in place already as 'info' exists; we just want to modify
the file descriptors, not the full PAGECACHE_FILE structure.
If we open data file and it was closed, share->bitmap.file needs
to be set.
Note that the modified code is disabled anyway.
storage/maria/ma_recovery.c:
Checkpoint record does not contain kfile/dfile descriptors anymore
so code can be simplified. Hash key in all_dirty_pages is
not made from file_descriptor & pageno anymore, but
index_or_data & table-short-id & pageno.
If a table's create_rename_lsn is higher than record's LSN,
we skip the table and don't fail if it's corrupted (because the LSNs
say that we don't have to look at this table).
If a table is skipped (for example due to create_rename_lsn),
its UNDOs still cause undo_lsn to advance; this is so that if later
we notice the transaction has to rollback we fail (as table should
not be skipped in this case).
Fixing a bug: the dirty_pages list was never used, because
the LSN below which it was used was the minimum rec_lsn of dirty pages!
It is now the min(checkpoint_start_log_horizon, min(trn's rec_lsn)).
When we disable/reenable transactionality, we modify pagecache
callbacks (needed for example for get_log_address: changing
share->page_type is not enough anymore).
storage/maria/ma_write.c:
'records' and 'checksum' are protected: they are updated under
log's mutex in write-hooks when UNDO is written.
storage/maria/maria_chk.c:
remove use of duplicate functions.
storage/maria/maria_def.h:
set_data|index_pagecache_callbacks() need to be exported;
_ma_reenable_logging_for_table() changes to a real function.

and let checkpoint wait for them to be flushable.

mysql-test/r/maria-recovery.result:

mysql-test/t/maria-recovery.test:
make it easier to locate subtests
storage/maria/ma_bitmap.c:
When we send a bitmap to the pagecache, if this bitmap is not in a
flushable state we keep it pinned and add it to a list, it will be
unpinned when the bitmap is flushable again.
A new function _ma_bitmap_flush_all() used by checkpoint.
A new function _ma_bitmap_flushable() used by block format to signal
when it starts modifying a bitmap and when it is done with it.
storage/maria/ma_blockrec.c:
When starting a row operation (insert/update/delete), mark that
the bitmap is not flushable (because for example INSERT is going
to over-allocate in the bitmap to prevent other threads from using
our data pages). If a checkpoint comes at this moment it will wait
for the bitmap to be flushable before flushing it.
When the operation ends, bitmap becomes flushable again; that
transition is done under the bitmap's mutex (needed for correct
synchro with a concurrent checkpoint); but for INSERT/UPDATE this
happens inside _ma_bitmap_release_unused() at a place where it already
has the mutex, so the only penalty (mutex adding) is in DELETE and UNDO
of INSERT. In case of errors after setting the bitmap unflushable,
we must always set it back to flushable or checkpoint would block.
Debug possibilities to force a sleep while the bitmap is over-allocated.
In case of error in get_head_or_tail() in allocate_and_write_block_record(),
we still need to unpin all pages.
Bugfix: _ma_apply_redo_insert_row_blobs() produced wrong
data_file_length.
storage/maria/ma_blockrec.h:
new bitmap calls.
storage/maria/ma_checkpoint.c:
filter_flush_indirect not needed anymore (flushing bitmap
pages happens in _ma_bitmap_flush_all() now). So
st_filter_param::is_data_file|pages_covered_by_bitmap not needed.
Other filter_flush* don't need to flush bitmap anymore.
Add debug possibility to flush all bitmap pages outside of a checkpoint,
to simulate pagecache LRU eviction.
When the background flush/checkpoint thread notices it has nothing
to flush, it now sleeps directly until the next potential checkpoint
moment instead of waking up every second.
When in checkpoint we decide to not store a table in the checkpoint record
(because it has logged no writes for example), we can also skip flushing
this table.

When we forget about an old transaction we must really forget
about it with bzero() (fixes the "long_trid!=0 assertion" recovery
bug). When we delete a row with maria_delete() we turn on
STATE_NOT_OPTIMIZED_ROWS so we do the same when we see a CLR_END
for an UNDO_ROW_INSERT or when we execute an UNDO_ROW_INSERT (in both
cases a row was deleted). Pick up max_long_trid from the checkpoint record.

When we log UNDO_KEY_INSERT for an auto_inc key, we update
state.auto_increment (not anymore at the end of maria_write() except
if this is a non-transactional table). When Recovery sees UNDO_KEY_INSERT
in the REDO phase, it reads the auto_inc value from it and updates
state.auto_increment.
mysql-test/r/maria-recovery.result:

storage/maria/ma_recovery.c:

(under log's mutex, so that a concurrent checkpoint does not read
state.auto_increment while it is changing - corrupted).

to write_hook_for_undo_key_insert().

Add _ma_unpin_all_pages() to all new UNDO redo_exec_hook's
possibility, if requested in the test, to do byte-for-byte comparison
of data files after recovery. This makes sense only when testing
REDOs, as UNDO phase generates new log records thus data pages get
new LSNs. First test of maria-recovery.test is changed to test only
REDOs and do byte-for-byte comparison.
mysql-test/include/maria_make_snapshot.inc:
possibility to compare physically the data files (makes sense
only if testing REDO phase).
mysql-test/include/maria_verify_recovery.inc:
allow physical comparison of data files after recovery if requested
mysql-test/r/maria-recovery.result:
result update (first test tests REDO only now)
mysql-test/t/maria-recovery.test:
first test tests REDO only now, and thus can do byte-for-byte
comparison of data files.
See test maria-recovery.test for a model; all include scripts have
an "API" section at start if they do take parameters from outside.
* Fixing bug reported by Jani and Monty (when two REDOs about the same
page in one group, see ma_blockrec.c).
* Fixing small bugs in recovery
mysql-test/include/wait_until_connected_again.inc:
be sure to enter the loop (the previous query by the caller may not have
failed: it could be
query;
mysqladmin shutdown;
call this script).
mysql-test/lib/mtr_process.pl:
* Through the "expect" file a test can tell mtr that a server crash
is expected. What the file contains is irrelevant. Now if its last
line starts with "wait", mtr will wait before restarting (it will
wait for the last line to not start with "wait"). This is for
tests which need to mangle files under the feet of a dead mysqld.
* Remove "expect" file before restarting; otherwise there could be a
race condition: tests sees server restarted, does something, writes
an "expect" file, and then mtr removes that file, then
test kills mysqld, and then mtr will never restart it.
storage/maria/ma_blockrec.c:
- when applying a REDO in recovery, we don't anymore put UNDO's LSN on the page
at once; indeed if in this REDO's group there comes another REDO
for the same page it would be wrongly skipped. Instead, we keep
pages pinned, don't change their LSN. When done with all REDOs
of the group we unpin them and stamp them with UNDO's LSN.
- fixing bug in applying of REDO_PURGE_BLOCKS in recovery: page_range
sometimes has TAIL_BIT set, need to turn it down to know the real page
range.
- Both bugs are covered in maria-recovery.test
storage/maria/ma_checkpoint.c:
Capability to, in debug builds only, do some special operations
(flush all bitmap and data pages, flush state, flush log)
and crash mysqld, to later test recovery.
Driven by some --debug=d, symbols.
storage/maria/ma_open.c:
debugging info
storage/maria/ma_pagecache.c:
Now that we can _ma_unpin_all_pages() during the REDO phase
to set page's LSN, the assertion needs to be relaxed.
storage/maria/ma_recovery.c:
- open trace file in append mode (useful when a test triggers several
recoveries, we see them all).
- fixing wrong error detection, it's possible that during recovery
we want to open an already open table.
- when applying a REDO in recovery, we don't anymore put UNDO's LSN on the page
at once; indeed if in this REDO's group there comes another REDO
for the same page it would be wrongly skipped. Instead, we keep
pages pinned, don't change their LSN. When done with all REDOs
of the group we unpin them and stamp them with UNDO's LSN.
- we verify that all log records of a group are about the same table,
for debugging.
mysql-test/r/maria-recovery.result:
result
mysql-test/t/maria-recovery-master.opt:
crash is expected, core file would take room, stack trace would
wake pushbuild up.
mysql-test/t/maria-recovery.test:
Test of recovery from mysql-test (it is already tested as unit tests
in ma_test_recovery) (WL#4137)
- test that, if recovery is made to start on an empty table it can
replay the effects of committed and uncommitted statements (having only
the committed ones in the end result). This should be the first test
for someone writing code of new REDOs.
- test that, if mysqld is crashed and recovery runs we have only
committed statements in the end result. Crashes are done in different
ways: flush nothing (so, uncommitted statement is often missing
from the log => no rollback to do); flush pagecache (implicitely flushes
log (WAL)) and flush log, both causes rollbacks; flush log can also
flush state (state.records etc) to test recovery of the state
(not tested well now as we repair the index anyway).
- test of bug found by Jani and Monty in recovery (two REDO about
the same page in one group).
mysql-test/include/maria_empty_logs.inc:
removes logs, to have a clean sheet for testing recovery.
mysql-test/include/maria_make_snapshot.inc:
copies a table to another directory, or back, or compares both
(comparison is not implemented as physical comparison is impossible
if an UNDO phase happened).
mysql-test/include/maria_make_snapshot_for_comparison.inc:
copies tables to another directory so that they can later
serve as a comparison reference (they are the good tables,
recovery should produce similar ones).
mysql-test/include/maria_make_snapshot_for_feeding_recovery.inc:
When we want to force recovery to start on old tables, we prepare
old tables with this script: we put them in a spare directory.
They are later copied back over mysqltest tables while mysqld is dead.
We also need to copy back the control file, otherwise mysqld,
in recovery, would start from the latest checkpoint: latest
checkpoint plus old tables is not a recovery-possible scenario of course.
mysql-test/include/maria_verify_recovery.inc:
causes mysqld to crash, restores old tables if requested,
lets recovery run, compares resulting tables with reference tables
by using CHECKSUM TABLE.
We don't do any sanity checks on page's LSN in resulting tables, yet.

- serializing calls to flush_pagecache_blocks_int() on the same file
to avoid known concurrency bugs
- having that, we can now enable the background thread, as the
flushes it does are now supposedly safe in concurrent situations.
- new type of flush FLUSH_KEEP_LAZY: when the background checkpoint
thread is flushing a packet of dirty pages between two checkpoints,
it uses this flush type, indeed if a file is already being flushed
by another thread it's smarter to move on to the next file than wait.
- maria_checkpoint_frequency renamed to maria_checkpoint_interval.
include/my_sys.h:
new type of flushing for the page cache: FLUSH_KEEP_LAZY
mysql-test/r/maria.result:
result update
mysys/mf_keycache.c:
indentation. No FLUSH_KEEP_LAZY support in key cache.
storage/maria/ha_maria.cc:
maria_checkpoint_frequency was somehow a hidden part of the
Checkpoint API and that was not good. Now we have checkpoint_interval,
local to ha_maria.cc, which serves as container for the user-visible
maria_checkpoint_interval global variable; setting it calls
update_checkpoint_interval which passes the new value to
ma_checkpoint_init(). There is no hiding anymore.
By default, enable background thread which does checkpoints
every 30 seconds, and dirty page flush in between. That thread takes
a checkpoint when it ends, so no need for maria_hton_panic to take one.
The | is | and not ||, because maria_panic() must always be called.
frequency->interval.
storage/maria/ma_checkpoint.c:
Use FLUSH_KEEP_LAZY for background thread when it flushes packets of
dirty pages between two checkpoints: it is smarter to move on to
the next file than wait for it to have been completely flushed, which
may take long.
Comments about flush concurrency bugs moved from ma_pagecache.c.
Removing out-of-date comment.

create_background_thread -> (interval>0).
In ma_checkpoint_background(), some variables need to be preserved
between iterations.
storage/maria/ma_checkpoint.h:
new prototype
storage/maria/ma_pagecache.c:
- concurrent calls of flush_pagecache_blocks_int() on the same file
cause bugs (see @note in that function); we fix them by serializing
in this situation. For that we use a global hash of (file, wqueue).
When flush_pagecache_blocks_int() starts it looks into the hash,
using the file as key. If not found, it inserts (file,wqueue) into the
hash, flushes the file, and finally removes itself from the hash and
wakes up any waiter in the queue. If found, it adds itself to the
wqueue and waits.
- As a by-product, we can remove changed_blocks_is_incomplete
and replace it by scanning the hash, replace the sleep() by a queue wait.
- new type of flush FLUSH_KEEP_LAZY: when flushing a file, if it's
already being flushed by another thread (even partially), return
immediately.
storage/maria/ma_pagecache.h:
In pagecache, a hash of files currently being flushed (i.e. there
is a call to flush_pagecache_blocks_int() for them).

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

Using an enum instead of 0/1/2 (applying Sanja's review comments).

created translog_next_LSN() which parse_checkpoint_record() uses.
Variables in ma_checkpoint_background() cannot be declared in the

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.

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.

mysql-test/t/maria.test:
testcase for a bug (used to segfault)
storage/maria/ma_blockrec.c:
When writing a record, we put BLOBs into the head part if there is
room for them. "Is there room" was first decided by
!(tmp_data + length > end_of_data) (line 1894)
but then was tested again as
*blob_lengths < (ulong)(end_of_data - data). We see that in case of
equality, the first condition was true but the second was not,
so it was inconsistent and crashed later.
storage/maria/ma_recovery.c:
When wondering if recovery should update the state (like state.records):
if table was closed, its is_of_horizon was set to X, then
table was reopened and a REDO was written. If this REDO had LSN
X (as horizon is just a lower bound of the LSN of the next record),
we have to apply it. In practice this equality probably could not
happen because of LOGREC_FILE_ID would be written before the REDO.

The parser uses ulonglong to store the LIMIT number. This number
then is stored into a variable of type ha_rows. ha_rows is either
4 or 8 byte depending on the BIG_TABLES define from config.h
So an overflow may occur (and LIMIT becomes zero) while storing an
ulonglong value in ha_rows.
Fixed by :
1. Using the maximum possible value for ha_rows on overflow
2. Defining BIG_TABLES for the windows builds (to match the others)

The optimizer sets index traversal in reverse order only if there are
used key parts that are not compared to a constant.
However using the primary key as an ORDER BY suffix rendered the check
incomplete : going in reverse order must still be used even if
all the parts of the secondary key are compared to a constant.
Fixed by relaxing the check and set reverse traversal even when all
the secondary index keyparts are compared to a const.
Also account for the case when all the primary keys are compared to a
constant.

Bug #31001:
- account for the case when all the primary key parts are compared
to a constant
- force test_if_skip_sort_order to go backwards over the key even
when the number of keyparts used is the same as the number of
keyparts equal to a constant. (because of the primary key
suffix).
