Percona XtraBackup 2.1.2 for MySQL

Percona XtraBackup 2.1.2 for MySQL 发布了，XtraBackup 是一个用来备份 MySQL 的 InnoDB 数据库的开源工具。

该版本主要修复了如下 bug：

• Using Perl’s DBD::MySQL package for server communication instead of spawning the MySQL command line client introduced a regression which caused innobackupex –galera-info option to fail. Bug fixed #1180672.
• The format of xtrabackup_galera_info was missing the ‘:’ separator between the values of wsrep_local_state_uuid and wsrep_last_committed. Bug fixed #1181222.
• innobackupex automatic version detection did not work correctly for latest Percona Server and MySQL 5.1 releases which could cause innobackupex to fail. Bugs fixed #1181092, #1181099 and #1180905.
• When backing up a server that is not a replication slave with the innobackupex –slave-info option, innobackupex failed with a fatal error. Replaced the fatal error with a diagnostic message about innobackupex –slave-info being ignored in such a case. Bug fixed #1180662.
• Low values for wait_timeout on the server could cause server to close the connection while backup is being taken. Fixed by setting the bigger value for wait_timeout option on the server to prevent server from closing connections if the global wait_timeout value is set too low. Bug fixed #1180922.
