Bug 修复：
After being rebased on MySQL 5.6.11 Percona XtraBackup has been affected by the upstream bug #69780. Fixed by rebasing Percona XtraBackup on MySQL 5.6.15 which contains a fix for the upstream bug. Bug fixed #1203669.
Backup directory would need to be specified even for running the innobackupex with
--helpand--versionoptions. Bug fixed #1223716.When creating an incremental backup with the changed page tracking feature available in Percona Server, innobackupexwould fail if the server had the
ANSI_QUOTESSQL mode enabled. Bug fixed #1248331.When innobackupex
--galera-infois specified and Percona XtraDB Cluster is usingGTIDreplication (version 5.6 only),innobackupex will executeFLUSH BINARY LOGSand then carry the current binary log as indicated inSHOW MASTER STATUSinto the backup set. Bug fixed #1250375.Percona XtraBackup did not roll back prepared
XAtransactions when applying the log. Which was a regression introduced with the original port of Percona XtraBackup patches to 5.6. Fixed by restoring code that has been lost in the port. Bug fixed #1254227.Percona XtraBackup now uses
libgcryptbuilt in randomization functions for setting the Initialization Vector. Bug fixed#1255300.xtrabackup_56didn’t supportALL_O_DIRECToption for innodb_flush_method in Percona Server 5.6. Bug fixed #1261877.
