Revision #3019 Tue 2011-08-16 19:01:31 +0300
Fixed wrong testcase
Tue 2011-08-16 13:28:20 +0300
Fixed build failure in embedded library regarding that decrease_user_connections() was not declared
Tue 2011-08-16 13:06:07 +0300
If mysqld --log-warnings=3 or higher, then print all check and repair warnings for MyISAM tables to the log.
This is useful when trying to find out why an automatic myisam repair failes.
Tue 2011-08-16 12:32:06 +0300
Fixed bug that MAX_USER_CONNECTIONS was not working properly in all situations (which could cause aborted connects)
thd->user_connect is now handled in thd->clenup() which will ensure that it works in all context (including slaves).
I added also some DBUG_ASSERT() to ensure that things are working correctly.
Mon 2011-08-15 23:53:55 +0300
Fixed recovery crash "Unclean shutdown corrupted Aria table blocking startup"
[merge] Mon 2011-08-15 20:42:29 +0300
Merge in bug fix from 5.1

Mon 2011-08-15 16:39:53 +0300
Fixes bugs found by testcase for and "ma_blockrec.c:3000: write_block_record: Assertion `cur_block[1].page_count == 0' failed with a multi-index Aria workload"
The issues was:
For some tables with a lot of not packed fields, we didn't allocate enough memory in head page which caused DBUG_ASSERT's
[merge] Fri 2011-08-12 15:51:05 +0300
Autmatic merge with 5.1
Fri 2011-08-12 15:40:56 +0300

Fixed 'Assertion `block->hash_link == hash_link && hash_link->block == block' in ma_pagecache.c:2275 with Aria'
Replaced old DBUG_ASSERT with a new correct one + a comment.
Wed 2011-08-10 13:08:19 +0300
Fixes MySQL bug#48972: mysqldump --insert-ignore leaves set unique_checks=0.
This fixes a bug that when you use mysqldump --no-create-info to generate a dump that you want to merge with an existing table,
you can get an innodb table with duplicated unique keys.

Thu 2011-06-30 00:37:12 +0300

Fri 2011-06-17 12:53:41 +0200
Fix for
Define USE_MARIA_FOR_TMP_TABLES preprocessor constant by default if Aria engine is compiled in.
Use CMake variable WITH_ARIA_TMP_TABLES to control the temp table engine setting.
The bug was that when using bulk insert combined with lock table, we intitalized the io cache with the wrong file position.
This fixed a bug where MariaDB could not read in a table dump done with mysqldump.
Removed wrong DBUG_ASSERT()
Fixed a problem with underflow() where it generates a key page where all keys didn't fit.
Max key length is now limited by block_size/3 (was block_size /2). This is required for underflow() to work with packed keys.
The bug was a wrong check in aria_chk; The table was fine.
Problem was the parsing of test suite files for various tags and options. This was done inefficiently, and include files were re-parsed for every place they were included. This caused a delay of 20 seconds or so before the first test started to run.
By parsing more efficiently and re-using first parse for subsequent inclusion of the same file, time spent parsing is reduced to less than 1 second, and start appears instantaneous.
(With this patch, full ./mtr runs in 3 minutes on my laptop (release build.)
Ensure that the last --datadir option is used from the my.cnf files.
Revision #2643.127.30 Sun 2011-07-24 01:25:28 -0700
Fixes Bug #805930 Sysbench breaks on multiple table test with MariaDB 5.2.7 + Aria
The bug happens when one uses MAX_ROWS=# with Aria & row_format=page and one insert more than # rows.
Revision #2643.127.29 Thu 2011-07-21 18:32:44 +0300
test fix.
Fixed explains of previous patch.
Revision #2643.127.26 Thu 2011-07-21 11:45:19 +0300
The function description added.
Revision #2643.127.25 Thu 2011-07-21 11:20:55 +0300
Fix of Bug #777809
There are 2 volatile condition constructions AND/OR constructions and fields(references) when first
good supported to be top elements of conditions because it is normal practice
(see copy_andor_structure for example) fields without any expression in the condition is really rare
and mostly useless case however it could lead to problems when optimiser changes/moves them unaware
of other variables referring to them. An easy solution of this problem is just to replace single field
in a condition with equivalent expression well supported by the server (<field> -> <field> != 0).
Revision #2643.127.23 Sun 2011-07-10 13:38:15 +0200
Post-fix for Bug #808233 : replace uint with "unsigned int" in mysql.h.pp, too

Sun 2011-07-10 12:27:42 +0200
fixes : Undefined uint in typelib.h
Fix is to replace uint in public header with unsigned int. uint is not guaranteed to be defined by system headers.
Revision #2643.127.21 Thu 2011-07-07 22:37:38 +0200
protocol safety fix:
before strlen(db) we need to be sure that db lies within packet boundaries
Much more DBUG_ASSERT(!maria_assert_if_crashed_table) to detect errors early
EXTERNAL_LOCKING -> MARIA_EXTERNAL_LOCKING (to use same define everywhere
Fixed bug in aria_chk that disabled performance counters.
Added --translog_buffer_size to maria_read_log.
Revision #2643.127.20 Fri 2011-06-24 10:56:29 +0300
Fixed typo. (Old code worked as both tested parts where 'bool', but not nice code..)
Revision #2643.127.19 Fri 2011-06-24 10:10:50 +0300
Fixes to aria
Fixed error when writing a blob to the last page on the bitmap.
Marked bitmap changed in once case that could cause two rows to use the same blob page.
Fri 2011-06-24 10:08:09 +0300
Fix for Incorrect "Duplicate entry" error with views and GROUP BY
Tue 2011-06-21 17:40:51 +0200
fix for MariaDB crashes on startup
initialize plugins earlier, to support, for example, non-MyISAM mysql.plugin table.
Wed 2011-06-15 20:30:10 +0200
./mtr --suite funcs_1 --ps-protocol
Wed 2011-06-15 19:44:00 +0200
fix "./configure --with-debug" builds
(without CFLAGS=-DSAFEMALLOC).
Revision #2993.1.2 Fri 2011-06-24 12:08:45 +0300
Fixed several errors in Aria discovered by test case for Bug #727869 ma_pagecache.c:2103: find_block: Assertion `block->rlocks == 0
Fixed assert in transaction log handler when aria_check was run on block-record table that was much bigger than expected.
Fixed warnings about wrong mutex order between bitmap and intern_lock
Fixed error in bitmap that could cause two rows to use same block for a block record.
Fixed wrong test that could cause error if last page for a bitmap was used by a blob.
Fixed several bugs in pagecache for the case where pagecase had very few blocks and there was a lot of threads competing to get the blocks (very unlikely case).
Revision #2993.1.1 Mon 2011-06-13 16:57:11 +0300
Change in PBXT to only use pth_set_priority() (not setpriority()) to set priority
