Due to incorrect usage of
posix_fadvise()hints, Percona XtraBackup discarded read-ahead buffers which resulted in higher
I/Orate on the backup stage. Bug fixed #1093385.
Spurious trailing data blocks that would normally be ignored by InnoDB could lead to an assertion failure on the backup stage. Bug fixed #1177201.
A spurious warning message could cause issues with third-party wrapper scripts. Bug fixed #1271956.
Preparing backups of MySQL or Percona Server 5.6 could raise an assertion failure in Percona XtraBackup. Bug fixed #1273468.
The downtime is decreased when the
--safe-slave-backupoption is used to backup a replication slave. The SQL thread is now started before a temporary copy of redo log is streamed into the final location. Bug fixed #1284778.
Disabled the “binary version check” functionality in the VersionCheck module due to security concerns. Bug fixed #1285166.
其他 bug 修复: #1284078.
