Percona Server 5.1.53-12.4 发布了,这是目前最新的稳定版本。

功能性的增加和改变:

  •  Percona Server 5.1.53-12.4 is based on MySQL 5.1.53.
  •  New Features Added:
  •  Other Changes:
    • innodb_doublewrite_file – It’s no longer necessary to recreate your database and InnoDB system files when a dedicated file to contain the doublewrite buffer is specified. (Yasufumi Kinoyasu)

修复的bug:

  • Bug #643149 – Slow query log entries were not written in the usual parsing format. (Alexey Kopytov)
  • Bug #671764innochecksum wasn’t distributed with RPM and .DEB packages. (Aleksandr Kuzminsky)
  • Bug #673426 – Use of these system variables as command-line options caused a crash or undefined behavior: log_slow_timestamp_every, log_slow_sp_statements, slow_query_log_microseconds_timestamp, use_global_long_query_time. (Oleg Tsarev)
  • Bug #673567 – Compiler could produce spurious warnings when building on non_Linux platforms. A check is now made to see if clock_gettime() is present in librt at the configure stage. If yes, -lrt is added to LIBS. (Alexey Kopytov)
  • Bug #673929 – Query cache misses were being reported for some queries when hits were actually occurring. (Oleg Tsarev)
  • Bug #676146 – The development environment test of log_slow_verbosity=innodb on a slave for row-based replication was not working correctly. (Oleg Tsarev)
  • Bug #676147, Bug #676148 – The development environment tests of options log_slow_slave_statements and use_global_long_query_time work only on statement-based replication. They were failing when row-based replication was attempted. A check is now made for the replication type to test. (Oleg Tsarev)
  • Bug #676158 – Setting the query cache size to 512M caused test failure on low memory systems. (Aleksandr Kuzminsky)
  • Bug #677407 – The innodb.innodb_information_schema test could fail sporadically due to flawed logic in the INFORMATION_SCHEMA.INNODB_LOCKS caching mechanism. (Alexey Kopytov)
  • Bug #681486 – A dependency between Debian packages libmysqlclient16 and percona-server-common was removed. (Aleksandr Kuzminsky)
  • Bug #693415 – The test percona_innodb_buffer_pool_shm was failing. It should be run with the --big-test option. As the buffer pool size used in the test is 128M, the shared memory segment should be increased appropriately in order to run the test successfully. (Aleksandr Kuzminsky)
  • Bug #693814, Bug #693815, Bug #693816, Bug #693817, Bug #693819 – Tests in the test environment were updated to reflect past INFORMATION_SCHEMA changes. (Aleksandr Kuzminsky)
  • Bug #693818 – Warning and error messages for stored routines could incorrectly report row numbers. This was because mysql_execute_command() unconditionally reset thd→row_count to 1 before statement execution in order to provide separate stats for individual statements in stored routines. The solution is to remember the row_count value at the start of statement execution instead of resetting it. Then the number of rows corresponding to the last statement can be calculated by subtracting the original value from the current one after statement execution. Since the regression tests for slow_extended were broken on Mac OS X, they were also fixed as a part of this bugfix. (Alexey Kopytov)
