Percona XtraBackup 2.2.7

Percona is glad to announce the release of Percona XtraBackup 2.2.7 on December 10th 2014. Downloads are available from our download site here and from apt and yum repositories.

This release is the current stable release in the 2.2 series.

Bugs Fixed

  • Non-default value for innodb_log_block_size variable would cause assertion when preparing the backup. Bug fixed #1391216.
  • When Percona XtraBackup would run FLUSH ENGINE LOGS during the backup process on GTID master, command was recorded to the slave’s binary log as well, which lead to inconsistency between master and slave. Fixed by adding the NO_WRITE_TO_BINLOG clause to FLUSH ENGINE LOGS to avoid interfering with binary log and inconsistency with coordinates. Bug fixed #1394632.
  • Exporting tables was inefficient when backup contained a large (and unrelated) change buffer. Bug fixed #1366065 (Davi Arnaut).
  • innobackupex was printing the GTID even if the GTID mode was disabled which could cause confusion since it wasn’t incrementing. Now it prints only GTID when GITD mode is enabled and when GTID mode is disabled it prints only filename and position. innobackupex still prints GTID, filename and positions if MariaDB server is being backed up. Bug fixed #1391041.

Other bugs fixed: #1386157.

All of Percona’s software is open-source and free, all the details of the release can be found in the 2.2.7 milestone at Launchpad. Bugs can be reported on the launchpad bug tracker.
