Bug fixes and beta support for Percona XtraDB Cluster and MySQL 5.6
Download files for this release
Percona Toolkit 2.1.8 has been released. This release includes 28 bug fixes, beta support for MySQL 5.6, and extensive support for Percona XtraDB Cluster (PXC). Users intending on running the tools on Percona XtraDB Cluster or MySQL 5.6 should upgrade. The following tools have been verified to work on PXC versions 5.5.28 and newer:
However, there are limitations when running these tools on PXC; see the Percona XtraDB Cluster section in each tool's documentation for further details. All other tools, with the exception of pt-slave-find, pt-slave-delay and pt-slave-restart, should also work correctly, but in some cases they have not been modified to take advantage of PXC features, so they may behave differently in future releases.
The bug fixes are widely assorted. The following highlights some of the more interesting and "hot" bugs:
* Fixed bug 1082599: pt-query-digest fails to parse timestamp with no query
Slow logs which include timestamps but no query--which can happen if using slow_query_
* Fixed bug 1078838: pt-query-digest doesn't parse general log with "Connect user as user"
The "as" was misparsed and the following word would end up reported as the database; pt-query-digest now handles this correctly.
* Fixed bug 1015590: pt-mysql-summary doesn't handle renamed variables in Percona Server 5.5
Some renamed variables had caused the Percona Server section to work unreliably.
* Fixed bug 1074179: pt-table-checksum doesn't ignore tables for --replicate-
When using --replicate-
* Fixed bug 886059: pt-heartbeat handles timezones inconsistently
Previously, pt-heartbeat respected the MySQL time zone, but this caused false readings (e.g. very high lag) with slaves running in different time zones. Now pt-heartbeat uses UTC regardless of the server or MySQL time zone.
* Fixed bug 1079341: pt-online-
Since MyISAM tables can't have foreign keys, and the tool uses the information_schema to find child tables, this could cause unnecessary load on the server.
2.1.8 continues the trend of solid bug fix releases, and all 2.1 users are encouraged to upgrade.
