Improvements and New Features

  • PXB-1548: Percona XtraBackup enables updating the ib_buffer_pool file with the latest pages present in the buffer pool by setting the xtrabackup --dump-innodb-buffer-pool option to ON. Thanks to Marcelo Altmann for contribution.

Bus Fixed

  • xtrabackup did not delete missing tables from the partial backup which led to error messages logged by the server on startup. Bug fixed PXB-1536.
  • The --history option did not work when autocommit was disabled. Bug fixed PXB-1569.
  • xtrabackup could fail to backup encrypted tablespace when it was recently created or altered. Bug fixed PXB-1648.
  • When the --throttle option was used, the applied value was different from the one specified by the user (off by one error). Bug fixed PXB-1668.
  • It was not allowed for MTS (multi-threaded slaves) without GTID to be backed up with --safe-slave-backup. Bug fixed PXB-1672.
  • Percona XtraBackup could crash when the ALTER TABLE TRUNCATE PARTITION command was run during a backup without locking DDL. Bug fixed PXB-1679.
  • xbcrypt could display an assertion failure and generated core if the required parameters are missing. Bug fixed PXB-1683.
  • Using --lock-ddl-per-table caused the server to scan all records of partitioned tables which could lead to the “out of memory” error. Bugs fixed PXB-1691 and PXB-1698.
  • xtrabackup –prepare could hang while performing insert buffer merge. Bug fixed PXB-1704.
  • Incremental backups did not update xtrabackup_binlog_info with --binlog-info=lockless. Bug fixed PXB-1711.

Other bugs fixed: PXB-1570, PXB-1609, PXB-1632
