Announcing Percona XtraBackup 2.0.4

Percona is glad to announce the release of Percona XtraBackup 2.0.4 on December 4th, 2012. Downloads are available from our download site here and Percona Software Repositories.

This release is the current GA (Generally Available) stable release in the 2.0 series.

Bugs Fixed:

• Bug fix for #932623 introduced the regression in XtraBackup 2.0.2 which caused incremental backups to fail because the init parameter values were not normalized to the values used inside InnoDB. Bug fixed #1062684 (Sergei Glushchenko).
• Bug fix for #932623 introduced the regression in XtraBackup 2.0.2 because it didn’t take the separate doublewrite tablespace into an account. Bug fixed #1066843 (Sergei Glushchenko).
• XtraBackup was handling the separate doublewrite buffer file incorrectly. File path of the doublewrite buffer wasn’t added to the backup-my.cnf and after the restore old doublewrite buffer file was used instead of one made during the prepare stage. Bug fixed #1068470 (Sergei Glushchenko).
• XtraBackup now accepts the --innodb=force option, previously it would throw an error if the option was set. Bug fixed #528752 (Laurynas Biveinis).
• Option safe-slave-backup wasn’t working correctly. Bug fixed #887803 (Alexey Kopytov).
• In case safe-slave-backup-timeout was reached when using the safe-slave-backup option, SQL_THREAD was left in stopped state causing the slave thread to lag behind. This was fixed by checking the initial SQL_THREAD state and starting it before terminating with a timeout error and starting the SQL_THREAD only if it was running initially. Bug fixed #1037379 (Alexey Kopytov).
• XtraBackup would fail on --apply-log when filesystem didn’t support Linux AIO. Bug fixed #1065561 (Alexey Kopytov).
• XtraBackup binary would ignore innodb_use_native_aio when it’s specified either in my.cnf or as a command line option. Bug fixed #1068459 (Alexey Kopytov).
• XtraBackup would print a warning message during the prepare stage about innodb_file_io_threads being deprecated, even if the variable wasn’t set. Bug fixed #1068485 (Alexey Kopytov).
• XtraBackup Galera tests can now be run concurrently. Bug fixed #1077800 (Stewart Smith).
