Improvements and New Features¶
- PXB-1548: Percona Xtrabackup enables updating the
ib_buffer_poolfile with the latest pages present in the buffer pool by setting thextrabackup --dump-innodb-buffer-pooloption to ON. Thanks to Marcelo Altmann for contribution.
Bus Fixed¶
-
xtrabackupdid not delete missing tables from the partial backup which led to error messages logged by the server on startup. Bug fixed PXB-1536. -
The
--historyoption did not work when autocommit was disabled. Bug fixed PXB-1569. -
xtrabackupcould fail to backup encrypted tablespace when it was recently created or altered. Bug fixed PXB-1648. -
When the
--throttleoption 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 PARTITIONcommand was run during a backup without locking DDL. Bug fixed PXB-1679. -
xbcryptcould display an assertion failure and generated core if the required parameters are missing. Bug fixed PXB-1683. -
Using
--lock-ddl-per-tablecaused 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_infowith--binlog-info=lockless. Bug fixed PXB-1711.
