Percona toolkit 2.1.7 is now available on Dotdeb for Debian 6.0 “Squeeze”. It includes some bug fixes and also :

• a plugin interface for pt-stalk
• a correct column renaming support for pt-online-schema-change
• and enchanced compatibility of pt-table-checksum with Percona XtraDB Cluster

Percona toolkit 2.1.5 is now available on Dotdeb for Debian 6.0 “Squeeze”. It includes only 3 bug fixes :

• pt-table-checksum 2.1.4 doesn’t detect diffs on Percona XtraDB Cluster nodes
• pt-table-checksum 2.1.4 miscategorizes Percona XtraDB Cluster-based slaves as cluster nodes
• pt-table-sync 2.1.4 –version-check may not work with HTTPS/SSL

As usual, please read the list of changes before upgrading.

Percona toolkit 2.1.4 is now available on Dotdeb for Debian 6.0 “Squeeze”. It includes 26 bug fixes and three new features:

• Making pt-table-checksum work with Percona XtraDB Cluster,
• adding a --run-time option to pt-table-checksum,
• and implementing the “Version Check” feature, enabled through the --version-check switch

As usual, please read the list of changes before upgrading.

Percona toolkit 2.1.2 is now available on Dotdeb for Debian 6.0 “Squeeze”. It brings a lot of bug fixes :

• pt-table-sync is now working properly, the --lock-and-rename feature has been disabled when using it with MySQL versions that don’t support it reliably.
• pt-table-checksum and pt-online-schema-change have been enhanced to add even more safety checks, and to detect and deal with some MySQL optimizer misbehaviors, as well as to handle more edge-case behaviors related to things like replication lag.
• A variety of bugfixes in pretty much every tool because of an expanded test coverage : more MySQL versions, more operating system platforms, more types of MySQL server settings, and more versions of Perl.
