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 wouldINSERT
it intopercona.deadlocks
table every minute until server was restarted. This was fixed by comparing with the last deadlock fingerprint before issuing theINSERT
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 .
