Percona Server version 5.5.35-33.0

Percona is glad to announce the release of Percona Server 5.5.35-33.0 on December 20th, 2013 (Downloads are available here and from the Percona Software Repositories). Based on MySQL 5.5.35, including all the bug fixes in it, Percona Server 5.5.35-33.0 is now the current stable release in the 5.5 series. All of Percona‘s software is open-source and free, all the details of the release can be found in the 5.5.35-33.0 milestone at Launchpad.

New Features:

Bugs Fixed:

  • INSTALL PLUGIN statement would crash server if User Statistics were enabled. Bug fixed #1011047.
  • Fixed the assertion error caused by a race condition between one thread performing a tablespace delete and another doing a compressed page flush list relocation. Bug fixed #1227581.
  • Server would crash on shutdown if Atomic write support for Fusion-io devices feature is enabled. Bug fixed #1255628 (Jan Lindström).
  • Fixed the compiler errors, caused by merge regression in Percona Server 5.5.33-31.1. Bug fixed #1218417.
  • mysqldump --innodb-optimize-keys was generating incorrect CREATE TABLE statements for partitioned tables. Bug fixed #1233841.
  • Default value for thread_pool_max_threads has been changed from 500 to 100 000 (the maximum supported number of connections), because limiting the total number of threads in the threadpool can result in deadlocks and uneven distribution of worker threads between thread groups in case of stalled connections. Bug fixed #1258097.
  • PURGE CHANGED_PAGE_BITMAPS BEFORE statement would delete the changed page data after the specified LSN and up to the start of the next bitmap file. If this data were to be used for fast incremental backups, its absence would cause Percona XtraBackup to fall back to the full-scan incremental backup mode. Bug fixed #1260035 (Andrew Gaul).
  • Debug server build would crash during InnoDB crash recovery if the crash recovery had found transactions that needed cleaning up. Bug fixed #1247305.
  • Variable thread_pool_high_prio_tickets is now a session variable. Bug fixed #1166271.

Other bugs fixed: bug #1082333.

Release notes for Percona Server 5.5.35-33.0 are available in our online documentation. Bugs can be reported on the launchpad bug tracker.

    Heads up for anyone looking at the RHEL / CentOS package. This version requires the OpenSSL package from 6.5. It will refuse to install on a system without that package.
