Functionality Added or Changed

  • Percona Server 5.1.52-12.3 is now based on MySQL 5.1.52.
  • New Features Added:
    • HandlerSocket plugin support has been added to all RPM and Debian packages. This is an experimental feature. (Inada Naoki, DeNA Co., Ltd.)
    • show_slave_status_nolock – Allows examination of slave status even when a lock prevents SHOW SLAVE STATUS from operating. (Oleg Tsarev)
    •  innodb_fast_shutdown – Sleeping threads could cause a delay of up to 10 seconds during InnoDB shutdown. The sleeping state of threads was made interruptible to avoid this. (contributed by Kristian Nielsen) (Alexey Kopytov)
  • Other Changes: None

Bugs Fixed

  • Bug #640576 – The false error “innodb_extra_undoslots option is disabled but it was enabled before” was sometimes reported after upgrading from MySQL 5.0. (Yasufumi Kinoyasu)
  • Bug #643463 – Shutting down XtraDB could take up to 10 seconds, even when there was no actual work to do. (Fix contributed by Kristian Nielsen) (Alexey Kopytov)
  • Bug #663757 – On the FreeBSD platform, the “gcc atomic built-in” function isn’t provided, so response_time_distribution now uses the native atomic API on FreeBSD. (Oleg Tsarev)
  • Bug #673426 – Use of some system variables as command-line options caused a crash or undefined behavior. (Oleg Tsarev)
  • Bug #673562 – Debug build was broken due a to failing compile-time assertion in mysqld.cc. (Alexey Kopytov)
  • 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 – The development environment test of option log_slow_slave_statements for row-based replication was not working correctly. (Oleg Tsarev)
  • Bug #676148 – Similar to Bug #676147. A check is now made for the replication type to test. (Oleg Tsarev)
