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.
