Revision #3019 Tue 2011-08-16 19:01:31 +0300
- Fixed wrong testcase
Revision #3018 Tue 2011-08-16 13:28:20 +0300
- Fixed build failure in embedded library regarding that decrease_user_connections() was not declared
Revision #3017 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.
Revision #3016 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.
Revision #3015 Mon 2011-08-15 23:53:55 +0300
- Fixed recovery crash Bug #814806 "Unclean shutdown corrupted Aria table blocking startup"
Revision #3014 [merge] Mon 2011-08-15 20:42:29 +0300
- Merge in bug fix from 5.1
  - Revision #2643.127.34 Mon 2011-08-15 20:38:21 +0300
    Fixed Bug #826377 "Aria DB Format: Reading specific table from dump causes Wrong bytesec"
    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.
Revision #3013 Mon 2011-08-15 20:40:13 +0300
- Increase server version
Revision #3012 Mon 2011-08-15 16:39:53 +0300
- Fixes bugs found by testcase for Bug #815022 and Bug #726374 "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
  - 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.
Revision #3011 [merge] Fri 2011-08-12 15:51:05 +0300
- Autmatic merge with 5.1
  - Revision #2643.127.33 Fri 2011-08-12 15:40:56 +0300
    Fixed Bug #814231 Aria post-recovery error "Bitmap at page 0 has pages reserved outside of data file length"
    The bug was a wrong check in aria_chk; The table was fine.
Revision #3010 Wed 2011-08-10 22:44:39 +0300
- Fixed Bug #814054 '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.
Revision #3009 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.
- Patch orignally by Eric Bergen.
Revision #3008 Mon 2011-08-08 14:53:52 +0300
- Optimize mutex usage.
Revision #3007 Mon 2011-08-01 10:56:24 +0200
- After-merge fix of result file (MARIA <-> Aria)
Revision #3006 [merge] Sun 2011-07-31 22:46:19 +0200
- Automerge 5.1->5.2
  - Revision #2643.127.32 Sun 2011-07-31 22:25:37 +0200
    Speed up mysql-test-run.pl.
    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.)

  - 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).
