      • Small Windows specific performance fixes:

        • Use native memcmp() supplied with C runtime instead of hand-unrolled loop ptr_compare_N loop

          • Prior to fix ptr_compare_0() has 3.7% samples in OLTP-RO in-memory.

          • Fix brings this down to 1.8% (all memcmp samples)

        • Innodb : fix UT_RELAX_CPU to be defined as YieldProcessor, as was also originally intended (but intention was lost in the #ifdef maze

      • This reduces number of ut_delay() samples in profile from 1.5% to 0.5%

    • Do not use Valgrind client requests in a normal release build, they have a small but noticable performance impact.

  • Revision #3340arrow-up-right Mon 2012-03-19 15:00:23 -0700

    • author: Davi Arnaut <davi 'at' twitter (dot) com>

    • Make Replication filter settings dynamic.

    • Make the slave options --replicate-* dynamic variables so that these options can be changed dynamically while the server is running, which enables users to modify replication filtering rules without having to stop and restart the server.

    • This is accomplished by just requiring that the slave threads are stopped when these options are set dynamically. Since filtering rules are only used by the SQL slave thread, setting them while the thread is not running avoids the need for locking.

  • Revision #3339arrow-up-right [merge] Wed 2012-03-21 15:51:13 +0100

    • merge

    • Revision #3333.1.1arrow-up-right Wed 2012-03-21 15:41:20 +0100

  • Revision #3338arrow-up-right Wed 2012-03-21 09:55:48 +0100

    • A few simple performance fixes found with sysbench oltp.lua and Oprofile:

      • Avoid needless load/stores in my_hash_sort_simple due to possible aliasing

      • Avoid expensive Join_plan_state constructor in choose_subquery_plan when no subquery

      • Avoid calling update_virtual_fields for every row when no virtual fields.

  • Revision #3336arrow-up-right Tue 2012-03-20 16:04:50 +0200

    • Fixed Bug #947474arrow-up-right "Assertion `table->file->stats.records > 0 || error' failed in join_read_const_table on concurrent SELECT and ALTER, constant Aria table"

    • Remove Aria state history for drop/rename

  • Revision #3335arrow-up-right Tue 2012-03-20 15:23:56 +0200

    • Cleanups:

      • Don't use SAFEMALLOC on valgrind builds (slows things down)

      • Added back lost option from 5.3: debug-mutex-deadlock-detector

      • Flush pages before taking lock mutex (speeds up closing of Aria tables).

  • Revision #3334arrow-up-right [merge] Sat 2012-03-17 12:16:57 -0700

  • Revision #3333arrow-up-right Fri 2012-03-16 20:52:17 +0100

    • Reduce size of windows MSI by approx. 50%

      • Mark test components, plugins etc with COMPONENT Test, to get them excluded from the MSI

      • Only include debug symbols for client and embedded libs and also mysqld.exe and server plugins (so we can still can get a callstack in case of crash)

    • The rest (all *.pdbs, test components, MTR) can be obtained from the big ZIP distribution, if required.

      • do not attempt loading federatedx dynamically - does not work on Windows embedded

      • race condition in rpl_start_stop_slave

      • fix exclusion rule to catch warning in partition test

  • Revision #3331arrow-up-right Thu 2012-03-15 00:37:37 +0100

    • Fix compile error - linker does not find extern variables, in sql_logger.c

    • The file uses external variables defined in another (C++) source file. Since MSVC mangles variables and not only functions, either variables in question should be extern "C", or sql_logger should be made C++ for link to succeed.

    • Fixed by renaming sql_logger.c to sql_logger.cc

      • mysys/my_logger.c was moved to sql/sql_logger.c

      • Logger service was rewritten with file functions instead of stream, so it can handle huge files.

  • Revision #3328arrow-up-right Wed 2012-03-14 09:40:54 +0400

    • plugin.result fixed.

  • Revision #3327arrow-up-right Wed 2012-03-14 00:55:56 +0400

    • MDEV-15arrow-up-right Log all SQL errors.

      • Added the logger service that provides us with the rotating logs.

        • The plugin SQL_ERROR_LOG added. It logs the errors using the 'logger service' for the rotating log files.

        • the example record from the log:2012-03-09 15:07:29 root[root] @ localhost [] ERROR 1146: Table 'test.xyz' doesn't exist : select * from test.xyz
