26565ae1d6 Aria issues:
- Fix for LP#700623 "Aria recovery: ma_blockrec.c:3930: _ma_update_at_original_place: Assertion `block->org_bitmap_value == _ma_bitmap_get_page_bits(info, &info->s->bitmap, page)' failed"
  - Issue was that when deleting a tail page where all index entries where full, the page was marked wrongly in the bitmap.
- If debug_assert_if_crashed_table is set, we now crash when we find Aria corrupted.
- Write more information if we find something wrong with the bitmap.
- Fixed that REPAIR also can fix wrong create_rename_lsn issues (a very unlikely event)
- Define STATE_CRASHED_FLAGS as set of all CRASHED flags (to simplify code)


storage/maria/ha_maria.cc:
  Mark the normal page cache (not the page cache for the logs) so that we can request extra debugging for it.
  Copy the value of debug_assert_if_crashed_table to maria_assert_if_crashed_table so that we can request a crash at exactly the point where we find Aria corrupted.
  Use STATE_CRASHED_FLAGS
storage/maria/ma_bitmap.c:
  Made bits_to_txt extern so that we can use this in maria_chk
  Added extra information to the log files to be able to easier find bitmap failures in recovery. (When compiling with -DEXTRA_DEBUG_BITMAP)
  Added _ma_get_bitmap_description() to request a clear text description of the bitmap.
  Simplify _ma_check_bitmap_data(), as we know the bitmap pattern in the caller.
storage/maria/ma_blockrec.c:
  In delete_head_or_tail(), fixed a bug where we sent wrong information to _ma_bitmap_set() if the directory was full for a page that should be freed.
  This fixed LP#700623 (failure in bitmap found during recovery)
storage/maria/ma_blockrec.h:
  Added definitions for _ma_get_bitmap_description() and bits_to_txt
storage/maria/ma_check.c:
  Simplify call to _ma_check_bitmap_data().
  Write more information if we find something wrong with the bitmap.
  Moved getting clear text information about the bitmap to ma_bitmap.c::_ma_get_bitmap_description()
storage/maria/ma_checkpoint.c:
  More asserts
storage/maria/ma_create.c:
  Fix wrong create_rename_lsn during repair.
  (Create_rename_lsn can be too big if someone restores an old maria_log_file after an Aria file was created)
storage/maria/ma_delete.c:
  Call _ma_set_fatal_error() in case of crashed file
  Remove not needed test of save_errno == HA_ERR_KEY_NOT_FOUND. (Handled by other code
storage/maria/ma_extra.c:
  Call _ma_set_fatal_error() in case of crashed file
  Reset share->bitmap.changed_not_flushed to not cause new ASSERTS to trigger.
  Added _ma_file_callback_to_id() for writing share->id to log file in case of DEBUG logging.
storage/maria/ma_init.c:
  Destroy also translog if it's readonly (as when called by maria_read_log -d)
storage/maria/ma_key.c:
  Call _ma_set_fatal_error() in case of crashed file
storage/maria/ma_key_recover.c:
  STATE_CRASHED -> STATE_CRASHED_FLAGS
storage/maria/ma_keycache.c:
  Call _ma_set_fatal_error() in case of crashed file
storage/maria/ma_locking.c:
  Call _ma_set_fatal_error() in case of crashed file.
  Added _ma_set_fatal_error()
storage/maria/ma_open.c:
  Call _ma_set_fatal_error() in case of crashed file
storage/maria/ma_page.c:
  Call _ma_set_fatal_error() in case of crashed file
storage/maria/ma_pagecache.c:
  Added extra information to log file to simply debugging of bitmap errors.
storage/maria/ma_pagecache.h:
  Added extra_debug flag to allow marking of row and index cache for extra logging (for debugging).
storage/maria/ma_panic.c:
  Flush both data and index blocks in case of HA_PANIC_CLOSE
  Fixed wrong position of 'break'. (Not critical for MariaDB as MariaDB never uses this code)
storage/maria/ma_recovery_util.c:
  Avoid writing extra not needed \n to DBUG log.
storage/maria/ma_rkey.c:
  Call _ma_set_fatal_error() in case of crashed file
storage/maria/ma_search.c:
  Call _ma_set_fatal_error() in case of crashed file
storage/maria/ma_static.c:
  Define maria_assert_if_crashed_table
storage/maria/ma_update.c:
  Call _ma_set_fatal_error() in case of crashed file.
  The new code also avoids a problem where we before would print the error twice.
storage/maria/ma_write.c:
  Call _ma_set_fatal_error() in case of crashed file
storage/maria/maria_chk.c:
  STATE_CRASHED -> STATE_CRASHED_FLAGS
storage/maria/maria_def.h:
  Added STATE_CRASHED_PRINTED to avoid giving error message about crash twice.
  Added STATE_CRASHED_FLAGS to be able to easily detect and set all CRASHED related flags.
  Added prototypes for new functions.
storage/myisam/mi_panic.c:
  Fixed wrong position of 'break'. (Not critical for MariaDB as MariaDB never uses this code)

6c9076256f issue an informative error message for a common Aria problem when opening a table
(incorrect block size)

418df96d51 use bulk insert and repair by sort for unique keys in
Aria and MyISAM in create_internal_tmp_table_from_heap()
(safe, as duplicates are impossible).
This gives a HUGE speed boost!

sql/opt_subselect.cc:
  Fixed problem with wrong recinfo in create_duplicate_weedout_tmp_tabl()
  Tagged the table with 'no_rows' so that when we create the table on disk,
  we only store the index data. This gave us a major speedup!
sql/sql_select.cc:
  create_tmp_table_from_heap() now uses bulk_insert + repair_by_sort
  when creating Aria/MyISAM tables from HEAP tables.
  This gives a HUGE speed boost!
storage/maria/ha_maria.cc:
  Extended bulk_insert() to recreate UNIQUE keys for
  internal temporary tables
storage/maria/ma_open.c:
  Initialize m_info->lock.type properly for temporarly tables
  (needed for start_bulk_insert())
storage/maria/ma_write.c:
  Don't check uniques that are disabled
storage/myisam/ha_myisam.cc:
  Extended bulk_insert() to recreate UNIQUE keys for
  internal temporary tables.

f5ea301acc Added support for NO_RECORD record format (don't store any row data) for Aria.
This makes the keys smaller (no row pointer) and gives us proper errors if we
use the table wrongly.

sql/sql_select.cc:
  Use NO_RECORD for tables that doesn't need row data.
storage/maria/Makefile.am:
  Added ma_norec.c
storage/maria/ma_check.c:
  Added support for NO_RECORD record format (don't store any row data)

  Added testing of NO_RECORD record format.
storage/maria/maria_chk.c:
  Added support for NO_RECORD
storage/maria/maria_def.h:
  Added support for NO_RECORD
storage/maria/unittest/ma_test_all-t:
  Added testing of NO_RECORD record format

20acfbf30d Fix for: LP #634955: Assert in _ma_update_at_original_place()
Added locking of lock mutex when updating status in external_unlock() for Aria and MyISAM tables.
Fixed that 'source' command doesn't cause mysql command line tool to exit on error.
DEBUG_EXECUTE() and DEBUG_EVALUATE_IF() should not execute things based on wildcards. (Allows one to run --debug with mysql-test-run scripts that uses @debug)
Fixed several core dump, deadlock and crashed table bugs in handling of LOCK TABLE with MERGE tables:
- Added priority of locks to avoid crashes with MERGE tables.
- Added thr_lock_merge() to allow one to merge two results of thr_lock().
Fixed 'not found row' bug in REPLACE with Aria tables.
Mark MyISAM tables that are part of MERGE with HA_OPEN_MERGE_TABLE and set the locks to have priority THR_LOCK_MERGE_PRIV.
- By sorting MERGE tables last in thr_multi_unlock() it's safer to release and relock them many times (can happen when TRIGGERS are created)
Avoid printing (null) in debug file (to easier find out wrong NULL pointer usage with %s).



client/mysql.cc:
  Fixed that 'source' command doesn't cause mysql command line tool to exit on error.
client/mysqltest.cc:
  Don't send NULL to fn_format(). (Can cause crash on Solaris when using --debug)
dbug/dbug.c:
  DEBUG_EXECUTE() and DEBUG_EVALUATE_IF() should not execute things based on wildcards.
include/my_base.h:
  Added flag to signal if one opens a MERGE table.
  Added extra() command to signal that one is not part of a MERGE table anymore.
include/thr_lock.h:
  Added priority for locks (needed to fix bug in thr_lock when using MERGE tables)
  Added option to thr_unlock() if get_status() should be called.
  Added prototype for thr_merge_locks().
mysql-test/mysql-test-run.pl:
  Ignore crashed table warnings for tables named 'crashed'.
mysql-test/r/merge.result:
  Renamed triggers to make debugging easier.
  Added some CHECK TABLES to catch errors earlier.
  Additional tests.
mysql-test/r/merge_debug.result:
  Test of error handling when reopening MERGE tables.
mysql-test/r/udf_query_cache.result:
  Added missing flush status
mysql-test/suite/parts/r/partition_repair_myisam.result:
  Update results
mysql-test/t/merge.test:
  Renamed triggers to make debugging easier.
  Added some CHECK TABLES to catch errors earlier.
  Additional tests.
mysql-test/t/merge_debug.test:
  Test of error handling when reopening MERGE tables.
mysql-test/t/udf_query_cache.test:
  Added missing flush status
mysys/my_getopt.c:
  Removed not used variable
mysys/my_symlink2.c:
  Changed (null) to (NULL) to make it easier to find NULL arguments to DBUG_PRINT() functions.
  (On linux, NULL to sprintf is printed 'null')
mysys/thr_lock.c:
  Added priority of locks to avoid crashes with MERGE tables.
  Added thr_lock_merge() to allow one to merge two results of thr_lock().
  - This is needed for MyISAM as all locked table must share the same status. If not, you will not see newly inserted rows in other instances of the table.
  If calling thr_unlock() with THR_UNLOCK_UPDATE_STATUS, call update_status() and restore_status() for the locks. This is needed in some rare cases where we call thr_unlock() followed by thr_lock() without calling external_unlock/external_lock in between.
  Simplify loop in thr_multi_lock().
  Added 'start_trans', which is called at end of thr_multi_lock() when all locks are taken.
  - This was needed by Aria to ensure that transaction is started when we got all locks, not at get_status(). Without this, some rows could not be visible when we lock two tables at the same time, causing REPLACE using two tables to fail unexpectedly.
sql/handler.cc:
  Add an assert() in handler::print_error() for "impossible errors" (like table is crashed) when --debug-assert-if-crashed-table is used.
sql/lock.cc:
  Simplify mysql_lock_tables() code if get_lock_data() returns 0 locks.
  Added new parameter to thr_multi_unlock()
  In mysql_unlock_read_tables(), call first externa_unlock(), then thr_multi_unlock();  This is same order as we do in mysql_unlock_tables().
  Don't abort locks in mysql_lock_abort() for merged tables when a MERGE table is deleted; Would cause a spin lock.
  Added call to thr_merge_locks() in mysql_lock_merge() to ensure consistency in thr_locks().
  - New locks of same type and table is stored after the old lock to ensure that we get the status from the original lock.
sql/mysql_priv.h:
  Added debug_assert_if_crashed_table
sql/mysqld.cc:
  Added --debug-assert-if-crashed-table
sql/parse_file.cc:
  Don't print '(null)' in DBUG_PRINT of no dir given
sql/set_var.cc:
  Increase default size of buffer for @debug variable.
sql/sql_base.cc:
  In case of error from reopen_table() in reopen_tables(), call unlock_open_table() and restart loop.
  - This fixed bug when we twice deleted same table from open_cache.
  Don't take name lock for already name locked table in open_unireg_entry().
  - Fixed bug when doing repair in reopen_table().
  - In detach_merge_children(), always detach if 'clear_refs' is given. We can't trust parent->children_attached as this function can be called twice, first time with clear_refs set to 0.
sql/sql_class.cc:
  Changed printing of (null) to "" in set_thd_proc_info()
sql/sql_parse.cc:
  Added DBUG
sql/sql_trigger.cc:
  Don't call unlink_open_table() if reopen_table() fails as the table may already be freed.
storage/maria/ma_bitmap.c:
  Fixed DBUG_ASSERT() in allocate_tail()
storage/maria/ma_blockrec.c:
  Fixed wrong calculation of row length for very small rows in undo_row_update().
  - Fixes ASSERT() when doing undo.
storage/maria/ma_blockrec.h:
  Added _ma_block_start_trans() and _ma_block_start_trans_no_versioning()
storage/maria/ma_locking.c:
  Call _ma_update_status_with_lock() when releasing write locks.
  - Fixes potential problem with updating status without the proper lock.
storage/maria/ma_open.c:
  Changed to use start_trans() instead of get_status() to ensure that we see all rows in all locked tables when we got the locks.
  - Fixed 'not found row' bug in REPLACE with Aria tables.
storage/maria/ma_state.c:
  Added _ma_update_status_with_lock() and _ma_block_start_trans().
  This is to ensure that we see all rows in all locked tables when we got the locks.
storage/maria/ma_state.h:
  Added _ma_update_status_with_lock()
storage/maria/ma_write.c:
  More DBUG_PRINT
storage/myisam/mi_check.c:
  Fixed error message
storage/myisam/mi_extra.c:
  Added HA_EXTRA_DETACH_CHILD:
  - Detach MyISAM table to not be part of MERGE table (remove flag & lock priority).
storage/myisam/mi_locking.c:
  Call mi_update_status_with_lock() when releasing write locks.
  - Fixes potential problem with updating status without the proper lock.
  Change to use new HA_OPEN_MERGE_TABLE flag to test if MERGE table.
  Added mi_fix_status(), called by thr_merge().
storage/myisam/mi_open.c:
  Added marker if part of MERGE table.
  Call mi_fix_status() in thr_lock() for transactional tables.
storage/myisam/myisamdef.h:
  Change my_once_flag to uint, as it stored different values than just 0/1
  Added 'open_flag' to store state given to mi_open()
storage/myisammrg/ha_myisammrg.cc:
  Add THR_LOCK_MERGE_PRIV to THR_LOCK_DATA to get MERGE locks sorted after other types of locks.
storage/myisammrg/myrg_locking.c:
  Remove windows specific code.
storage/myisammrg/myrg_open.c:
  Use HA_OPEN_MERGE_TABLE to mi_open().
  Set HA_OPEN_MERGE_TABLE for linked MyISAM tables.
storage/xtradb/buf/buf0buf.c:
  Fixed compiler warning
storage/xtradb/buf/buf0lru.c:
  Initialize variable that could be used not initialized.

b9890b0544 Fix for LP#634943 "marked as crashed", "zerofilling" and "wrong data in bitmap" when recovering Aria tables
This was an interaction of several bugs:
- Tables marked as opened was not properly unmarked on recovery if there was not changes since checkpoint
- zerofill of tables put wrong data in bitmap if directory for page was full
- Tables was thought as 'moved' during recovery if they had a create_lsn bigger than the lsn in the control file.


storage/maria/ha_maria.cc:
  If table is moved and crashed, threat it as crashed.
  (Not a related to this bug, but still good to have fixed)
storage/maria/ma_blockrec.c:
  Make enough_free_entries_on_page() global
storage/maria/ma_blockrec.h:
  Make enough_free_entries_on_page() global
storage/maria/ma_check.c:
  If directory is full, mark page full. Fixes bug in zerofill
storage/maria/ma_open.c:
  Don't marke files as MOVED during recovery if create_trid > trnman_max_trid, as this fails for tables created after checkpoint.
storage/maria/ma_recovery.c:
  Reset open_count in file that was open during crash and was part of checkpoint.
  Fixed wrong warning of 'open count' after recovery of files that was not touched since checkpoint.
storage/maria/maria_chk.c:
  Changed not documented option --log-dir to --logdir
  Document more of the options.
  Clean up output for --help
storage/maria/trnman.c:
  Added DBUG_PRINT

0f3d4b2f76 Fixed bug that 'maria_read_log -a' didn't set max_trid when reparing tables.
Fixed bug in Aria when replacing short keys with long keys and a key tree both overflow and underflow at same time.
Fixed several bugs when generating recovery logs when using RGQ with replacing long keys with short keys and vice versa.
Lots of new DBUG_ASSERT()'s
Added more information to recovery log to make it easier to know from where log entry orginated.
Introduced MARIA_PAGE->org_size that tells what the size of the page was in last log entry. This allows us to find out if all key changes for index page was logged.
Small code cleanups:
- Introduced _ma_log_key_changes() to log crc of key page changes
- Added share->max_index_block_size as max size of data one can put in key block (block_size - KEYPAGE_CHECKSUM_SIZE)
  This will later simplify adding a directory to index pages.
- Write page number instead of page postition to DBUG log



mysql-test/lib/v1/mysql-test-run.pl:
  Use --general-log instead of --log to disable warning when using RQG
sql/mysqld.cc:
  If we have already sent ok to client when we get an error, log this to stderr
  Don't disable option --log-output if CSV engine is not supported.
storage/maria/ha_maria.cc:
  Log queries to recovery log also in LOCK TABLES
storage/maria/ma_check.c:
  If param->max_trid is set, use this value instead of max_trid_in_system().
  This is used by recovery to set max_trid to max seen trid so far.
  keyinfo->block_length - KEYPAGE_CHECKSUM_SIZE -> max_index_block_size (Style optimization)
storage/maria/ma_delete.c:
  Mark tables crashed early
  Write page number instead of page position to debug log.
  Added parameter to ma_log_delete() and ma_log_prefix() that is logged so that we can find where wrong log entries where generated.
  Fixed bug where a page was not proplerly written when same key tree had both an overflow and underflow when deleting a key.
  keyinfo->block_length - KEYPAGE_CHECKSUM_SIZE => max_index_block_size (Style optimization)
  ma_log_delete() now has extra parameter of how many bytes from end of page should be appended to log for page (for page overflows)
storage/maria/ma_key_recover.c:
  Added extra parameter to ma_log_prefix() to indicate what caused log entry.
  Update MARIA_PAGE->org_size when logging info about page.
  Much more DBUG_ASSERT()'s.
  Fix some bugs in maria_log_add() to handle page overflows.
  Added _ma_log_key_changes() to log crc of key page changes.
  If EXTRA_STORE_FULL_PAGE_IN_KEY_CHANGES is defines, log the resulting pages to log so one can trivally
  see how the resulting page should have looked like (for errors in CRC values)
storage/maria/ma_key_recover.h:
  Added _ma_log_key_changes() which is only called if EXTRA_DEBUG_KEY_CHANGES is defined.
  Updated function prototypes.
storage/maria/ma_loghandler.h:
  Added more values to en_key_debug, to get more exact location where things went wrong when logging to recovery log.
storage/maria/ma_open.c:
  Initialize share->max_index_block_size
storage/maria/ma_page.c:
  Added updating and testing of MARIA_PAGE->org_size
  Write page number instead of page postition to DBUG log
  Generate error if we read page with wrong data.
  Removed wrong assert: key_del_current != share->state.key_del.
  Simplify _ma_log_compact_keypage()
storage/maria/ma_recovery.c:
  Set param.max_trid to max seen trid before running repair table (used for alter table to create index)
storage/maria/ma_rt_key.c:
  Update call to _ma_log_delete()
storage/maria/ma_rt_split.c:
  Use _ma_log_key_changes()
  Update MARIA_PAGE->org_size
storage/maria/ma_unique.c:
  Remove casts
storage/maria/ma_write.c:
  keyinfo->block_length - KEYPAGE_CHECKSUM_SIZE => share->max_index_block_length.
  Updated calls to _ma_log_prefix()
  Changed code to use _ma_log_key_changes()
  Update ma_page->org_size
  Fixed bug in _ma_log_split() for pages that overflow

ec281a3c34 Fixed some bugs in the Maria storage engine
- Changed default recovery mode from OFF to NORMAL to get automatic repair of not properly closed tables.
- Fixed a rase condition when two threads calls external_lock and thr_lock() in different order. When this happend the transaction that called external lock first
  and thr_lock() last did not see see the rows from the other transaction, even if if it had to wait in thr_lock() for other to complete.
- Fixed that one can run maria_chk on an automatcally recovered tables without warnings about too small transaction id
- Don't give warning that crashed table could not be repaired if repair was disabled (and thus not run)
- Fixed a error result from flush_key_cache() which caused a DBUG_ASSERT() when one was using concurrent reads on non transactional tables that was updated.

client/mysqldump.c:
  Add "" around error message to make it more readable
client/mysqltest.cc:
  Free environment variables
mysql-test/r/mysqldump.result:

storage/maria/ha_maria.cc:
  Changed default recovery mode from OFF to NORMAL to get automatic repair of not properly closed tables.
  Start transaction in ma_block_get_status() instead of in ha_maria::external_lock().
  - This fixes a rase condition when two threads calls external lock and thr_lock() in different order. When this happend the transaction that called external lock first and thr_lock() last did not see see the rows from the other transaction, even if if it had to wait in thr_lock() for other to complete.
  Store latest transaction id in controll file if recovery was done.
  - This allows one to run maria_chk on an automatcally recovered tables without warnings about too small transaction id
storage/maria/ha_maria.h:
  Don't give warning that crashed table could not be repaired if repair was disabled (and thus not run)
storage/maria/ma_blockrec.h:
  Added new function "_ma_block_get_status_no_versioning()"
storage/maria/ma_init.c:
  Added hook to create trn in ma_block_get_status() if we are using MariaDB
storage/maria/ma_open.c:
  Ensure we call _ma_block_get_status_no_versioning() for transactional tables without versioning (like tables with fulltext)
storage/maria/ma_pagecache.c:
  Allow one to flush blocks that are pinned for read.
  This fixed a error result from flush_key_cache() which caused a DBUG_ASSERT() when one was using concurrent reads on non transactional tables that was updated.
storage/maria/ma_recovery.c:
  Set maria_recovery_changed_data to 1 if recover changed something.
  Set max_trid_in_control_file to max found trn if we found a bigger trn.
  The allows will ensure that the control file is up to date after recovery which allows one to run maria_chk on the tables without warnings about too big trn
storage/maria/ma_state.c:
  Call maria_create_trn_hook() in _ma_setup_live_state() instead of ha_maria::external_lock()
  This ensures that 'state' and trn are in sync and thus fixes the race condition mentioned for ha_maria.cc
storage/maria/ma_static.c:
  Added maria_create_trn_hook() and maria_recovery_changed_data
storage/maria/maria_def.h:
  Added MARIA_HANDLER->external_ptr, which is used to hold MariaDB thd.
  Added some new external variables
  Removed reference to non existing function: maria_concurrent_inserts()

c9a29373e1 Fix for BUG#41159 "Maria: deadlock between checkpoint and maria_write() when extending data file".
No testcase (concurrency, tested by pushbuild2).

storage/maria/ha_maria.cc:
  a comment about what Sanja had discovered a while ago
storage/maria/ma_bitmap.c:
  guard against concurrent flush of bitmap by checkpoint: we must have close_lock here
storage/maria/ma_blockrec.c:
  comment fixed for new behaviour
storage/maria/ma_checkpoint.c:
  Release intern_lock before flushing bitmap, or it deadlocks with allocate_and_write_block_record()
  when that function needs to increase the data file's length (that function makes bitmap non flushable,
  then wants intern_lock to increase data_file_length).
  The checkpoint section which looks at the share's content (bitmap, state) needs to be protected from the possible
  my_free-ing done by a concurrent maria_close(); intern_lock is not enough as
  both maria_close() and checkpoint now have to release it in the middle.
  So the protection is done with close_lock. in_checkpoint is now protected by close_lock
  in places where it was protected by intern_lock.
storage/maria/ma_close.c:
  hold close_lock in maria_close() from start to end, to guard against checkpoint trying to flush
  bitmap while we have my_free'd its structures, for example. intern_lock was not enough as
  both maria_close() and checkpoint have to release it in the middle, to avoid deadlocks.
storage/maria/ma_open.c:
  initialize new mutex
storage/maria/ma_recovery.c:
  a comment about what Sanja had discovered a while ago

ade71b2522 Fix for BUG#39697 "Maria: hang when failing to insert due to UNIQUE (seen in pushbuild2 too)"
It was a forgotten rw_unlock(), due to the deadlock detector feature (so bug was only in 5.1-maria, not
6.0-maria).

mysql-test/suite/maria/r/maria3.result:
  result, all fine
mysql-test/suite/maria/t/maria3.test:
  Test of BUG#39697: two scenarios (transactional tables, and non-transactional table but dynamic row format so still taking the rwlock) where the hang happened.
  t2 added by this test was masked by a temporary table created earlier in the test, which we forgot to drop.
storage/maria/ha_maria.cc:
  use new macro
storage/maria/ma_blockrec.c:
  use new macro
storage/maria/ma_commit.c:

  if local_lock_tree is true, we have acquired keyinfo->root_lock so need to release it before "goto err".
  A pair of assertions so that our usage of TrIDs is kept sensible.
storage/maria/maria_def.h:
  A macro so that changes of MARIA_HA::trn can be tracked with --debug. It helped to understand in what cases,
  in maria_write(), we could have !(info->dup_key_trid == info->trn->trid) && !share->now_transactional
  (answer: ALTER TABLE adding UNIQUE index on transactional table).

81d3d3ac42 - lifting a limit: INSERT|REPLACE SELECT and LOAD DATA always prevented versioning, now what do so is if
the table is empty.
- lifting another limit: versioning was disabled if table had more than one unique index
- correcting test of statement-based binlogging, when converting read locks to TL_READ_NO_INSERT

KNOWN_BUGS.txt:
  removing mostly fixed limitation (see ha_maria.cc)
mysql-test/r/maria-mvcc.result:
  result update
mysql-test/t/maria-mvcc.test:
  now when table is empty it does not do versioning, so test hung; inserting one row at start of the test,
  to enable versioning.
sql/sql_parse.cc:
  Maria team wrongly removed this "break", thanks Davi for noticing
storage/maria/ha_maria.cc:
  - We used to prevent versioning in INSERT/REPLACE SELECT and LOAD DATA, because the index rebuild done by
  bulk insert sometimes, is unsafe when versioning is on. Here we change that: in store_lock(), if the table is empty
  (which is required for index rebuild to be used), we disable versioning; in start_bulk_insert(), we don't do
  index rebuild if versioning is enabled.
  - Test for statement-based binlogging was incomplete: statement-based binlogging is on for this statement
  if binlog is open and statement has binlogging enabled and statement is not doing row-based binlogging
storage/maria/ma_open.c:
  Monty and I agreed that it's ok to have versioning on a table with more than one unique index: if an INSERT
  hits a duplicate key when inserting the second index' key, no other thread should be able to touch the 
  first index' just-inserted key, because that key has an uncommitted transaction id, so the first thread
  should have time to remove the first index' key.

60b88ce475 Fix for BUG#37876 "Importing Maria table from other server via binary copy does not work":
- after auto-zerofill (ha_maria::check_and_repair()) kepts its state's LSNs unchanged, which could
be the same as the create_rename_lsn of another pre-existing table, which would break versioning as this LSN
serves as unique identifier in the versioning code (in maria_open()). Even the state pieces which
maria_zerofill() did change were lost (because they didn't go to disk).
- after this fix, if two tables were auto-zerofilled at the same time (by _ma_mark_changed())
they could receive the same create_rename_lsn, which would break versioning again. Fix is to write a log
record each time a table is imported.
- Print state's LSNs (create_rename_lsn, is_of_horizon, skip_redo_lsn) and UUID in maria_chk -dvv.

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

  is imported into a Maria instance.
storage/maria/ma_create.c:
  Write LOGREC_IMPORTED_TABLE when importing a table. This is informative and ensures

  are imported by concurrent threads (it advances the log's end LSN).

f27efe69f5 Disable versioning (concurrent writes) if more than one unique key
The reason for this is that if we change one unique key and then get a failure on the second, we may not be able to rename the first one back before someone else writes the same key value.  In Maria 2.0, when we keep deleted key values in the tree, this will not be a problem anymore

Added some minor changes that was done in my tree while waiting for test to run:
- Remove in Maria T_QUICK when retrying repair for enabling indexes, as the record file may be in use by other threads
- Disable code that is only relevant for EXTERNAL_LOCKING

52cb0c24a6 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

.bzrignore:

extra/Makefile.am:
  comp_err is now deleted on make distclean
include/maria.h:
  Added structure MARIA_KEY, which is used for intern key objects in Maria.

  Changed some functions that always return true or false to my_bool.
  Added virtual function make_key() to avoid if in _ma_make_key()
  Moved rw_lock_t for locking trees from share->key_root_lock to MARIA_KEYDEF. This makes usage of the locks simpler and faster
include/my_base.h:
  Added HA_RTREE_INDEX flag to mark rtree index. Used for easier checks in ma_check()
  Added SEARCH_INSERT to be used when inserting new keys
  Added SEARCH_PART_KEY for partial searches
  Added SEARCH_USER_KEY_HAS_TRANSID to be used when key we use for searching in btree has a TRANSID
  Added SEARCH_PAGE_KEY_HAS_TRANSID to be used when key we found in btree has a transid
include/my_handler.h:
  Make next_flag 32 bit to make sure we can handle all SEARCH_ bits
mysql-test/include/maria_empty_logs.inc:
  Read and restore current database; Don't assume we are using mysqltest.
  Don't log use databasename to log. Using this include should not cause any result changes.

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
  Added comparision of transid. This is only done if the keys actually have a transid, which is indicated by nextflag

storage/maria/ha_maria.cc:
  Use 'file->start_state' as default state for transactional tables without versioning
  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

  Fixed wrong usage of HA_PACK_RECORD (should be HA_OPTION_PACK_RECORD)
  Mark keys that uses HA_KEY_ALG_RTREE with HA_RTREE_INDEX for easier handling of these in ma_check
  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.
storage/maria/ma_dbug.c:
  Changed _ma_print_key() to use MARIA_KEY
storage/maria/ma_delete.c:
  Modified functions to use MARIA_KEY instead of key pointer and key length

  Use share->row_is_visible() to test if row is visible
  Moved search_flag == HA_READ_KEY_EXACT out of 'read-next-row' loop as this only need to be tested once
  Removed test if last_used_keyseg != 0 as this is always true

  If there may be keys with transid on the page, have _ma_bin_search() call _ma_seq_search()
  Add _ma_skip_xxx() functions to quickly step over keys (faster than calling get_key() in most cases as we don't have to copy key data)
  Combine similar code at end of _ma_get_binary_pack_key()
  Removed not used function _ma_move_key()
  In _ma_search_next() don't call _ma_search() if we aren't on a nod page.

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
  Keep share->state.state.data_file_length up to date (not info->state->data_file_length)
  Moved _ma_block_xxxx_status() and maria_versioning() functions to ma_state.c
storage/maria/ma_check.c:

  info->s to share
  Update info->state at end of repair
  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:

  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

  Versioning of count(*) and checksum:
  - Use share->state.state instead of info->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

  Versioning of count(*) and checksum:
  - Always update info->state->checksum and info->state->records

ab0fa111fe Fixed bug in restoring auto-increment value in case of duplicate key with insert or update
Fixed bug when calculating max_key_length that caused some ALTER TABLE to fail if MAX_ROWS was used.
Use maria_block_size instead of MARIA_MIN_KEY_BLOCK_LENGTH
Fixed bug when scanning table with BLOCK format for repair; If table was > bitmap coverage one page block was read twice which caused a lot of duplicate key errors
Could not repeat Bug#34106 "auto_increment is reset to 1 when table is recovered from crash" after this patch.

NOTE: This is an incompatible change, so one must do maria_chk -r on ones old Maria tables!
Sorry, but this was needed to fix the bug with max_key_length and to be able to handle bigger key files with smaller key references

534417c285 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.

  new flag: bulk insert repair mustn't bump create_rename_lsn
mysql-test/lib/mtr_report.pl:

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

  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).

unknown
b5df1d3446 Bugs fixed:
- If not in autocommit mode, delete rows one by one so that we can roll back if necessary
- bitmap->used_size was not correctly set, which caused bitmap pages to be overwritten
- Fixed bug in bitmap handling when allocation tail pages
- Ensure we reserve place for directory entry when calculation place for head and tail pages
- Fixed wrong value in bitmap->size[0]
- Fixed wrong assert in flush_log_for_bitmap
- Fixed bug in _ma_bitmap_release_unused() where tail blocks could be wrongly reset
- Mark new pages as changed (Required to get repair() to work)
- Fixed problem with advancing log horizon pointer within one page bounds
- Fixed DBUG_ASSERT() when enable_indexes failes for end_bulk_insert()
- Fixed bug in logging of rows with more than one big blob
- Fixed DBUG_ASSERTS() in pagecache to allow change of WRITE_LOCK to READ_LOCK in unlock() calls
- Flush pagecache when we change from logging to not logging (if not, pagecache code breaks)
- Ensure my_errno is set on return from write/delete/update
- Fixed bug when using FIELD_SKIP_PRESPACE

New features:
- mysql_fix_privilege_tables now first uses binaries and scripts from source distribution, then in installed distribution
- Fix that optimize works for Maria tables
- maria_check --zerofill now also clear freed blob pages
- maria_check -di now prints more information about record page utilization

Optimizations:
- Use pagecache_unlock_by_link() instead of pagecache_write() if possible. (Avoids a memory copy and a find_block)
- Simplify code to abort when we found optimal bit pattern
- Skip also full head page bit patterns when searching for tail
- Increase default repair buffer to 128M for maria_chk and maria_read_log
- Increase default sort buffer for maria_chk to 64M
- Increase size of sortbuffer and pagecache for mysqld to 64M
- VARCHAR/CHAR fields are stored in increasing length order for BLOCK_RECORD tables

Better reporting:
- Fixed test of error condition for flush (for better error code)
- More error messages to mysqld if Maria recovery fails
- Always print warning if rows are deleted in repair
- Added global function _db_force_flush() that is usable when doing debugging in gdb
- Added call to my_debug_put_break_here() in case of some errors (for debugging)
- Remove used testfiles in unittest as these was written in different directories depending on from where the test was started

This should fix the bugs found when importing a big table with many varchars and one/many blobs to Maria

  Added DBUG_ASSERT() to find out if row sizes are calculated wrong
  Fixed bug in logging of rows with more than one big blob
storage/maria/ma_check.c:
  Disable logging while normal repair is done to avoid logging of index changes
  Fixed bug that caused CHECKSUM part of key page to be used
  Fixed that deleted of wrong records also works for BLOCK_RECORD
  Clear unallocated pages:
  - BLOB pages are not automaticly cleared on delete, so we need to use the bitmap to know if page is used or not
  Better error reporting
  More information about record page utilization
  Change printing of file position to printing of pages to make output more readable
  Always print warning if rows are deleted
storage/maria/ma_create.c:

  I prefer to use NULL for 'no callback' instead of a dummy callback
  in the special case of get_log_address; indeed for non-transactional
  tables it uses an if(), while if using a dummy callback, it would
  use a function call plus an if() (the dummy callback would need to
  return a magic value to say "don't flush" and that value would be
  tested in if()).

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

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

18bc7b695a WL#3072 - Maria Recovery
* to honour WAL we now force the whole log when flushing a bitmap page.
* ability to intentionally crash in various places for recovery testing
* bugfix (dirty pages list found in checkpoint record was ignored)
* smaller checkpoint record
* misc small cleanups and comments

sql/sql_table.cc:
  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_extra.c:
  Monty fixed
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.
storage/maria/unittest/ma_pagecache_consist.c:

d72c22dee4 WL#3072 - Maria recovery.
* fix for bitmap vs checkpoint bug which could lead to corrupted
tables in case of crashes at certain moments: a bitmap could be flushed
to disk even though it was inconsistent with the log (it could be
flushed before REDO-UNDO are written to the log). One bug remains, need
code from others. Tests added. Fix is to pin unflushable bitmap pages,
and let checkpoint wait for them to be flushable.
* fix for long_trid!=0 assertion failure at Recovery.
* less useless wakeups in the background flush|checkpoint thread.
* store global_trid_generator in checkpoint record.


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

storage/maria/ma_recovery.c:
  Comments. Now-unneeded code for incomplete REDO-UNDO groups removed.
  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.
storage/maria/maria_chk.c:
  comment
storage/maria/maria_def.h:
  MARIA_FILE_BITMAP gets new members: 'flushable', 'bitmap_cond' and

storage/maria/trnman.c:
  I used to think that recovery only needs to know the maximum TrID
  of the lists of active and committed transactions. But no, sometimes
  both lists can even be empty and their TrID should not be reused.
  So Checkpoint now saves global_trid_generator in the checkpoint record.
storage/maria/trnman_public.h:

5fbd5dafe7 * WL#4137 Maria- Framework for testing recovery in mysql-test-run
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.

d0b9387b88 WL#3072 - Maria recovery.
* Recovery of the table's live checksum (CREATE TABLE ... CHECKSUM=1)
is achieved in this patch. The table's live checksum
(info->s->state.state.checksum) is updated in inwrite_rec_hook's
under the log mutex when writing UNDO_ROW_INSERT|UPDATE|DELETE
and REDO_DELETE_ALL. The checksum variation caused by the operation
is stored in these UNDOs, so that the REDO phase, when it sees such
UNDOs, can update the live checksum if it is older (state.is_of_lsn is
lower) than the record. It is also used, as a nice add-on with no
cost, to do less row checksum computation during the UNDO phase
(as we have it in the record already).
Doing this work, it became pressing to move in-write hooks
(write_hook_for_redo() et al) to ma_blockrec.c.
The 'parts' argument of inwrite_rec_hook is unpredictable (it comes
mangled at this stage, for example by LSN compression) so it is
replaced by a 'void* hook_arg', which is used to pass down information,
currently only to write_hook_for_clr_end() (previous undo_lsn and
type of undone record).
* If from ha_maria, we print to stderr how many seconds (with one
fractional digit) the REDO phase took, same for UNDO phase and for
final table close. Just to give an indication for debugging and maybe
also for Support.


storage/maria/ha_maria.cc:
  question for Monty
storage/maria/ma_blockrec.c:
  * log in-write hooks (write_hook_for_redo() etc) move from
  ma_loghandler.c to here; this is natural: the hooks are coupled
  to their callers (functions in ma_blockrec.c).
  * translog_write_record() now has a new argument "hook_arg";
  using it to pass down to write_hook_for_clr_end() the transaction's
  previous_undo_lsn and the type of the being undone record, and also
  to pass down to all UNDOs the live checksum variation caused by the
  operation.
  * If table has live checksum, store in UNDO_ROW_INSERT|UPDATE|DELETE
  and in CLR_END the checksum variation ("delta") caused by the
  operation. For example if a DELETE caused the table's live checksum
  to change from 123 to 456, we store in the UNDO_ROW_DELETE, in 4 bytes,
  the value 333 (456-123).
  * Instead of hard-coded "1" as length of the place where we store
  the undone record's type in CLR_END, use a symbol CLR_TYPE_STORE_SIZE;
  use macros clr_type_store and clr_type_korr.
  * write_block_record() has a new parameter 'old_record_checksum'
  which is the pre-computed checksum of old_record; that value is used
  to update the table's live checksum when writing UNDO_ROW_UPDATE|CLR_END.
  * In allocate_write_block_record(), if we are executing UNDO_ROW_DELETE
  the row's checksum is already computed.
  * _ma_update_block_record2() now expect the new row's checksum into
  cur_row.checksum (was already true) and the old row's checksum into
  new_row.checksum (that's new). Its two callers, maria_update() and
  _ma_apply_undo_row_update(), honour this.
  * When executing an UNDO_ROW_INSERT|UPDATE|DELETE in UNDO phase, pick
  up the checksum delta from the log record. It is then used to update
  the table's live checksum when writing CLR_END, and saves us a
  computation of record.
storage/maria/ma_blockrec.h:
  in-write hooks move from ma_loghandler.c
storage/maria/ma_check.c:
  more straightforward size of buffer
storage/maria/ma_checkpoint.c:
  <= is enough
storage/maria/ma_commit.c:
  new prototype of translog_write_record()
storage/maria/ma_create.c:
  new prototype of translog_write_record()
storage/maria/ma_delete.c:
  The row's checksum must be computed before calling(*delete_record)(),
  not after, because it must be known inside _ma_delete_block_record()
  (to update the table's live checksum when writing UNDO_ROW_DELETE).
  If deleting from a transactional table, live checksum was already updated
  when writing UNDO_ROW_DELETE.
storage/maria/ma_delete_all.c:
  @todo is now done (in ma_loghandler.c)
storage/maria/ma_delete_table.c:
  new prototype of translog_write_record()
storage/maria/ma_loghandler.c:
  * in-write hooks move to ma_blockrec.c.
  * translog_write_record() gets a new argument 'hook_arg' which is
  passed down to pre|inwrite_rec_hook. It is more useful that 'parts'
  for those hooks, because when those hooks are called, 'parts' has
  possibly been mangled (like with LSN compression) and is so
  unpredictable.
  * fix for compiler warning (unused buffer_start when compiling without
  debug support)
  * Because checksum delta is stored into UNDO_ROW_INSERT|UPDATE|DELETE
  and CLR_END, but only if the table has live checksum, these records
  are not PSEUDOFIXEDLENGTH anymore, they are now VARIABLE_LENGTH (their
  length is X if no live checksum and X+4 otherwise).
  * add an inwrite_rec_hook for UNDO_ROW_UPDATE, which updates the
  table's live checksum. Update it also in hooks of UNDO_ROW_INSERT|
  DELETE and REDO_DELETE_ALL and CLR_END.
  * Bugfix: when reading a record in translog_read_record(), it happened
  that "length" became negative, because the function assumed that
  the record extended beyond the page's end, whereas it may be shorter.
storage/maria/ma_loghandler.h:
  * Instead of hard-coded "1" and "4", use symbols and macros
  to store/retrieve the type of record which the CLR_END corresponds
  to, and the checksum variation caused by the operation which logs the
  record
  * translog_write_record() gets a new argument 'hook_arg' which is
  passed down to pre|inwrite_rec_hook. It is more useful that 'parts'
  for those hooks, because when those hooks are called, 'parts' has
  possibly been mangled (like with LSN compression) and is so
  unpredictable.
storage/maria/ma_open.c:
  fix for "empty body in if() statement" (when compiling without safemutex)
storage/maria/ma_pagecache.c:
  <= is enough
storage/maria/ma_recovery.c:
  * print the time that each recovery phase (REDO/UNDO/flush) took;
  this is enabled only when recovering from ha_maria. Is it printed
  n seconds with a fractional part of one digit (like 123.4 seconds).
  * In the REDO phase, update the table's live checksum by using
  the checksum delta stored in UNDO_ROW_INSERT|DELETE|UPDATE and CLR_END.
  Update it too when seeing REDO_DELETE_ALL.
  * In the UNDO phase, when executing UNDO_ROW_INSERT, if the table does
  not have live checksum then reading the record's header (as done by
  the master loop of run_undo_phase()) is enough; otherwise we
  do a translog_read_record() to have the checksum delta ready
  for _ma_apply_undo_row_insert().
  * When at the end of the REDO phase we notice that there is an unfinished
  group of REDOs, don't assert in debug binaries, as I verified that it
  can happen in real life (with kill -9)
  * removing ' in #error as it confuses gcc3
storage/maria/ma_rename.c:
  new prototype of translog_write_record()
storage/maria/ma_test_recovery.expected:
  Change in output of ma_test_recovery: now all live checksums of
  original tables equal those of tables recreated by the REDO phase
  and those of tables fixed by the UNDO phase. I.e. recovery of
  the live checksum looks like working (which was after all the only
  goal of this changeset).
  I checked by hand that it's not just all live checksums which are
  now 0 and that's why they match. They are the old values like
  3757530372. maria.test has hard-coded checksum values in its result
  file so checks this too.
storage/maria/ma_update.c:
  * It's useless to put up HA_STATE_CHANGED in 'key_changed',
  as we put up HA_STATE_CHANGED in info->update anyway.
  * We need to compute the old and new rows' checksum before calling
  (*update_record)(), as checksum delta must be known when logging
  UNDO_ROW_UPDATE which is done by _ma_update_block_record(). Note that
  some functions change the 'newrec' record (at least _ma_check_unique()
  does) so we cannot move the checksum computation too early in the
  function.
storage/maria/ma_write.c:
  If inserting into a transactional table, live's checksum was
  already updated when writing UNDO_ROW_INSERT. The multiplication
  is a trick to save an if().

cec8ac3e07 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 :)

  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.

  * 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.

  found in the Checkpoint record apply (new mappings should not apply

2291f932b2 - WL#3072 Maria Recovery:
Recovery of state.records (the count of records which is stored into
the header of the index file). For that, state.is_of_lsn is introduced;
logic is explained in ma_recovery.c (look for "Recovery of the state").
The net gain is that in case of crash, we now recover state.records,
and it is idempotent (ma_test_recovery tests it).
state.checksum is not recovered yet, mail sent for discussion.
- WL#3071 Maria Checkpoint: preparation for it, by protecting
all modifications of the state in memory or on disk with intern_lock
(with the exception of the really-often-modified state.records,
which is now protected with the log's lock, see ma_recovery.c
(look for "Recovery of the state"). Also, if maria_close() sees that
Checkpoint is looking at this table it will not my_free() the share.
- don't compute row's checksum twice in case of UPDATE (correction
to a bugfix I made yesterday).


storage/maria/ha_maria.cc:
  protect state write with intern_lock (against Checkpoint)
storage/maria/ma_blockrec.c:
  * don't reset trn->rec_lsn in _ma_unpin_all_pages(), because it
  should wait until we have corrected the allocation in the bitmap
  (as the REDO can serve to correct the allocation during Recovery);
  introducing _ma_finalize_row() for that.
  * In a changeset yesterday I moved computation of the checksum
  into write_block_record(), to fix a bug in UPDATE. Now I notice
  that maria_update() already computes the checksum, it's just that
  it puts it into info->cur_row while _ma_update_block_record()
  uses info->new_row; so, removing the checksum computation from
  write_block_record(), putting it back into allocate_and_write_block_record()
  (which is called only by INSERT and UNDO_DELETE), and copying
  cur_row->checksum into new_row->checksum in _ma_update_block_record().
storage/maria/ma_check.c:
  new prototypes, they will take intern_lock when writing the state;
  also take intern_lock when changing share->kfile. In both cases
  this is to protect against Checkpoint reading/writing the state or reading
  kfile at the same time.
  Not updating create_rename_lsn directly at end of write_log_record_for_repair()
  as it wouldn't have intern_lock.
storage/maria/ma_close.c:
  Checkpoint builds a list of shares (under THR_LOCK_maria), then it
  handles each such share (under intern_lock) (doing flushing etc);
  if maria_close() freed this share between the two, Checkpoint
  would see a bad pointer. To avoid this, when building the list Checkpoint
  marks each share, so that maria_close() knows it should not free it
  and Checkpoint will free it itself.
  Extending the zone covered by intern_lock to protect against
  Checkpoint reading kfile, writing state.
storage/maria/ma_create.c:
  When we update create_rename_lsn, we also update is_of_lsn to
  the same value: it is logical, and allows us to test in maria_open()
  that the former is not bigger than the latter (the contrary is a sign
  of index header corruption, or severe logging bug which hinders
  Recovery, table needs a repair).
  _ma_update_create_rename_lsn_on_disk() also writes is_of_lsn;
  it now operates under intern_lock (protect against Checkpoint),
  a shortcut function is available for cases where acquiring
  intern_lock is not needed (table's creation or first open).
storage/maria/ma_delete.c:
  if table is transactional, "records" is already decremented
  when logging UNDO_ROW_DELETE.
storage/maria/ma_delete_all.c:
  comments
storage/maria/ma_extra.c:
  Protect modifications of the state, in memory and/or on disk,
  with intern_lock, against a concurrent Checkpoint.
  When state goes to disk, update it's is_of_lsn (by calling
  the new _ma_state_info_write()).
  In HA_EXTRA_FORCE_REOPEN, don't set share->changed to 0 (undoing
  a change I made a few days ago) and ASK_MONTY
storage/maria/ma_locking.c:
  no real code change here.
storage/maria/ma_loghandler.c:
  Log-write-hooks for updating "state.records" under log's mutex
  when writing/updating/deleting a row or deleting all rows.
storage/maria/ma_loghandler_lsn.h:
  merge (make LSN_ERROR and LSN_REPAIRED_BY_MARIA_CHK different)
storage/maria/ma_open.c:
  When opening a table verify that is_of_lsn >= create_rename_lsn; if
  false the header must be corrupted.
  _ma_state_info_write() is split in two: _ma_state_info_write_sub()
  which is the old _ma_state_info_write(), and _ma_state_info_write()
  which additionally takes intern_lock if requested (to protect
  against Checkpoint) and updates is_of_lsn.
  _ma_open_keyfile() should change kfile.file under intern_lock
  to protect Checkpoint from reading a wrong kfile.file.
storage/maria/ma_recovery.c:
  Recovery of state.records: when the REDO phase sees UNDO_ROW_INSERT
  which has a LSN > state.is_of_lsn it increments state.records.
  Same for UNDO_ROW_DELETE and UNDO_ROW_PURGE.
  When closing a table during Recovery, we know its state is at least
  as new as the current log record we are looking at, so increase
  is_of_lsn to the LSN of the current log record.
storage/maria/ma_rename.c:
  update for new behaviour of _ma_update_create_rename_lsn_on_disk().
storage/maria/ma_test1.c:
  update to new prototype
storage/maria/ma_test2.c:

d53991853e - 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.

* create page cache before initializing engine and not after, because

* make the creation of a bitmap page more crash-resistent
* bugfix (see ma_blockrec.c)
* back to old way: create an 8k bitmap page when creating table
* preparations for the UNDO phase: recreate TRNs
* preparations for Checkpoint: list of dirty pages, testing
of rec_lsn to know if page should be skipped during Recovery
(unused in this patch as no Checkpoint module pushed yet)
* maria_chk tags repaired table with a special LSN
* reworking all around in ma_recovery.c (less duplication)


mysys/my_realloc.c:
  noted an issue in my_realloc()
sql/mysqld.cc:
  page cache needs to be created before engines are initialized,
  because Maria's initialization may do a recovery which needs
  the page cache.
storage/maria/ha_maria.cc:
  update to new prototype
storage/maria/ma_bitmap.c:
  when creating the first bitmap page we used chsize to 8192 bytes then 
  pwrite (overwrite) the last 2 bytes (8191-8192). If crash between
  the two operations, this leaves a bitmap page full without its end
  marker. A later recovery may try to read this page and find it
  exists and misses a marker and conclude it's corrupted and fail.
  Changing the chsize to only 8190 bytes: recovery will then find
  the page is too short and recreate it entirely.
storage/maria/ma_blockrec.c:
  Fix for a bug: when executing a REDO, if the data page is created,
  data_file_length was increased before _ma_bitmap_set():
  _ma_bitmap_set() called _ma_read_bitmap_page() which, due to the
  increased data_file_length, expected to find a bitmap page on disk
  with a correct end marker; if the bitmap page didn't exist already
  in fact, this failed. Fixed by increasing data_file_length only after
  _ma_read_bitmap_page() has created the new bitmap page correctly.
  This bug could happen every time a REDO is about creating a new
  bitmap page.
storage/maria/ma_check.c:
  empty data file has a bitmap page

  useless parameter to ma_control_file_create_or_open(), just

95e2558f8e * "transactionality" needs to be preserved by TRUNCATE TABLE:
a table with TRANSACTIONAL=x needs to still have it after TRUNCATE.
No testcase, but without this fix, the frm and the Maria table
got "out of sync" in this case:
create table t1 (a int) row_format=page transactional=0;
truncate table t1;
After TRUNCATE, the Maria table (not the frm) was transactional
(thus logging records, which is wrong).
* fix for non-closed file at end of "maria_chk -r"


sql/table.cc:
  "transactionality" needs to be preserved when truncating.
  It's behind a if() to not cancel the hack added to mysql_truncate()
  today for temporary Maria tables.

storage/maria/ma_create.c:
  debugging info
storage/maria/ma_open.c:
  fix for datafile left open at end of "maria_chk -r":
  ma_open_datafile() happens after _ma_bitmap_init(), it sets dfile.file
  so needs to set share->bitmap.file.file too (they are copies of
  each other). Otherwise it breaks how closing of files works in
  BLOCK_RECORD (which is that info.dfile.file is not closed
  but share->bitmap.file.file is closed): not setting share->bitmap.file.file
  can lead to forgetting to close a file or closing a wrong file.

* Don't modify share->base.born_transactional; now it is a value carved
in stone at creation time. share->now_transactional is what can be
modified: it starts at born_transactional, can become false during
ALTER TABLE (when we want no logging), and restored later.
* Not resetting create_rename_lsn to 0 during delete_all or repair.
* when we temporarily disable transactionality, we also change
the page type to PAGECACHE_PLAIN_PAGE: it bypasses some work in the
page cache (optimization), and avoids assertions related to LSNs.
* Disable INSERT DELAYED for transactional tables, because
durability could not be guaranteed (insertion may even not happen)


mysys/mf_keycache.c:
  comment
storage/maria/ha_maria.cc:
  * a transactional table cannot do INSERT DELAYED
  * ha_maria::save_transactional not needed anymore, as now instead
  we don't modify MARIA_SHARE::MARIA_BASE_INFO::born_transactional
  (born_transactional plays the role of save_transactional), and modify
  MARIA_SHARE::now_transactional.
  * REPAIR_TABLE log record is now logged by maria_repair()
  * comment why we rely on born_transactional to know if we should
  skipping a transaction.
  * putting together two if()s which test for F_UNLCK
storage/maria/ha_maria.h:
  ha_maria::save_transactional not needed anymore (moved to the C layer)
storage/maria/ma_blockrec.c:
  * For the block record's code (writing/updating/deleting records),
  all that counts is now_transactional, not born_transactional.
  * As we now set the page type to PAGECACHE_PLAIN_PAGE for tables
  which have now_transactional==FALSE, pagecache will not expect
  a meaningful LSN for them in pagecache_unlock_by_link(), so
  we can pass it LSN_IMPOSSIBLE.
storage/maria/ma_check.c:
  * writing LOGREC_REPAIR_TABLE moves from ha_maria::repair()
  to maria_repair(), sounds cleaner (less functions to export).
  * when opening a table during REPAIR, don't use the realpath-ed name,
  as this may fail if the table has symlinked files (maria_open()
  would try to find the data and index file in the directory
  of unique_file_name, it would fail if data and index files are in
  different dirs); use the unresolved name, open_file_name, which is
  the argument which was passed to the maria_open() which created 'info'.

  also no reason to do it during repair: it was put there because
  a positive create_rename_lsn caused a call to check_and_set_lsn()
  which asserted in DBUG_ASSERT(block->type == PAGECACHE_LSN_PAGE);
  first solution was to use LSN_IMPOSSIBLE in _ma_unpin_all_pages() if
  not transactional; but then in the case of ALTER TABLE, with
  transactionality temporarily disabled, it asserted in
  DBUG_ASSERT(LSN_VALID(lsn)) in pagecache_fwrite() (PAGECACHE_LSN_PAGE
  page with zero LSN - bad). The additional solution is to use
  PAGECACHE_PLAIN_PAGE when we disable transactionality temporarily: this
  avoids checks on the LSN, and also bypasses (optimization) the "flush
  log up to LSN" call when the pagecache flushes our page (in other
  words, no WAL needed).

0cf96a3206 WL#3072 - Maria recovery
For this scenario: server crashes (could be because a table is
corrupted) and Recovery repeatedly crashes on this table. User repairs
it with maria_chk (as REPAIR TABLE is not possible), restarts the
server, Recovery runs: for Recovery to not apply old REDOs to this
repaired table (which would fail: rows have moved), maria_chk sets
create_rename_lsn to the max value. Later when the server opens
the table via ha_maria, it sets the LSN to the correct current value.


storage/maria/ma_check.c:
  using helper function
storage/maria/ma_create.c:
  A new helper function which stores the create_rename_lsn 
  into the table's header on disk when we cannot wait for this to happen
  naturally at a later _ma_state_info_write().
storage/maria/ma_delete_all.c:
  using helper function; so log_data now can be FILEID_STORE_SIZE.
storage/maria/ma_open.c:
  When opening a transactional table in the server, we discover
  if it has been repaired with maria_chk and if yes, give it a correct
  create_rename_lsn.
storage/maria/ma_rename.c:
  using helper function
storage/maria/maria_chk.c:
  By setting create_rename_lsn to the maximum possible LSN, maria_chk
  ensures that old REDOs are not applied to the new table it is
  going to produce.

1a96259191 - 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_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/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.
