MySQL 热备工具 Percona XtraBackup 2.2.5 发布,该版本重新基于 MySQL 5.6.21 进行开发。

修复了如下 Bug:

  • The fix for bug #1079700 introduced a problem for users with huge numbers of InnoDB tablespaces, and the workaround of raising the open files limits didn’t work in all cases due to a limitation in the Linux kernel. A new innobackupex --close-files option has been implemented to close the file handles once they are no longer accessed. NOTE: Using this option may result in a broken backup if DDL is performed on InnoDB tables during the backup procedure. Bug fixed #1222062.

  • Fix for bug #1206309 introduced a regression in Percona XtraBackup 2.2.0 which caused Percona XtraBackup to fail to copy redo logs in random cases. Bug fixed #1365835.

  • innobackupex --galera-info didn’t copy the last binlog file when it was taking a backup from server where backup locks are supported. Bug fixed #1368577.

  • xtrabackup binary would accept arguments that were not options, which could lead to unexpected results. Bug fixed #1367377.

  • If innobackupex is run against MySQL 5.1 with built-in InnoDB, it will now suggest using Percona XtraBackup 2.0 or upgrading to InnoDB plugin, rather than just failing with the generic unsupported server version message. Bug fixed #1335101.

  • Using the (deprecated) log parameter in mysqld section would cause backups to fail. Bug fixed #1347698.

  • Percona XtraBackup now uses MySQL code to get the stack trace in case Percona XtraBackup crashes with a segmentation fault or an assertion failure. Bug fixed #766305.

  • Attempt to use any of the following options without the --incremental option now fails with an error message rather than creates a full backup: --incremental-lsn, --incremental-basedir, --incremental-history-name, --incremental-history-uuid. Bug fixed #1213778.

其他 bugs 修复: #1367613, #1368574, #1370462, #1371441, #1373429, #1373984, and #1265070.
