Percona is glad to announce the release of Percona XtraBackup 2.2.12 on August 3rd 2015. Downloads are available from our download site here and from apt and yum repositories.

Bugs Fixed

Percona XtraBackup would segfault during the prepare phase of certain FTS pages. Bug fixed #1460138.

Fixed compilation error due to missing dependency caused by the upstream bug #77226. Bug fixed #1461129.

Regression introduced by fixing a bug #1403237 in Percona XtraBackup 2.2.8 could cause xtrabackup to read a redo log from incorrect offset which would cause an assertion. Bug fixed #1464608.

Fixed uninitialized current_thd thread-local variable. This also completely fixes #1415191. Bug fixed #1467574.

After the release of Percona XtraBackup 2.2.11, innobackupex issues a FLUSH TABLE before running the FLUSH TABLES WITH READ LOCK. While it will help the backups in some situation, it also implies that the FLUSH TABLE will be written to the binary log. On MariaDB 10.0 with GTID enabled, when backup was taken on the slave, this altered the GTID of that slave and Percona XtraBackup didn’t see the correct GTID anymore. Bug fixed #1466446 (Julien Pivotto).

RPM compilation of Percona XtraBackup was still requiring bzr. Bug fixed #1466888 (Julien Pivotto).

Compiling Percona XtraBackup RPMs with XB_VERSION_EXTRA option would create an incorrect RPM version. Bug fixed #1467424 (Julien Pivotto).

Percona XtraBackup would complete successfully even when redo log wasn’t copied completely. This means that backup were considered successful even when they were corrupt. Bug fixed #1470847.

In rare cases when there are two or more tablespaces with the same ID in the data directory, xtrabackup picks up the first one by lexical order, which could lead to losing the correct table. Bug fixed #1475487.

Percona XtraBackup was missing revision_id in binaries. Bug fixed #1394174.

All of Percona’s software is open-source and free, all the details of the release can be found in the 2.2.12 milestone at Launchpad. Bugs can be reported on the launchpad bug tracker.
