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.bitscn.com
