  • 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 #3005 [merge] Mon 2011-07-25 21:52:15 -0700
  • Revision #3004 [merge] Thu 2011-07-21 15:21:22 +0300
  • Revision #3003 [merge] Thu 2011-07-21 13:15:09 +0300
    • Merge 5.1->5.2
      • Revision #2643.127.27 Thu 2011-07-21 12:29:00 +0300
        • Removed incorrect fix and its test suite (the test suit is duplicate).
        • 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).
