Percona Toolkit 2.2.9 is now available_MySQL

percona is glad to announce the release of  percona toolkit 2.2.9 on july 10, 2014 (downloads are available  here  and from the  percona software repositories ) . this release is the current ga (generally available) stable release in the 2.2 series.

Bugs Fixed:

• Fixed bug 1335960 : pt-query-digest could not parse the binlogs from MySQL 5.6 because the binlog format was changed.
• Fixed bug 1315130 : pt-online-schema-change did not find child tables as expected. It could incorrectly locate tables – tables which reference a table with the same name in a different schema, and could miss tables referencing the altered table – if they were in a different schema..
• Fixed bug 1335322 : pt-stalk would fail when variable or threshold was a non-integer.
• Fixed bug 1258135 : pt-deadlock-logger was inserting older deadlocks into the deadlock table even if it was already there, therby creating unnecessary noise. For example, if the deadlock happened 1 year ago, and MySQL keeps it in the memory, pt-deadlock-logger would INSERT it into percona.deadlocks table every minute until server was restarted. This was fixed by comparing with the last deadlock fingerprint before issuing the INSERT query.
• Fixed bug 1329422 : pt-online-schema-change foreign-keys-method=none can break FK constraints in a way that is hard to recover from. Although this method of handling foreign key constraints is provided so that the database administrator can disable the tool’s built-in functionality if desired, a warning and confirmation request when using alter-foreign-keys-method “none” has been added to warn users when using this option.

Percona Toolkit is free and open-source. Details of the release can be found in the release notes and the  2.2.9 milestone at Launchpad . Bugs can be reported on the Percona Toolkit launchpad bug tracker .
