Percona Toolkit moved to https://jira.percona.com/projects/PT 2.1.3

Percona Toolkit 2.1.3 has been released. This release includes 31 bug fixes and one new feature: pt-kill --log-dsn to log information about killed queries to a table. The bug fixes are widely assorted. The following highlights some of the more interesting and "hot" bugs:

* Fixed bug 916168: pt-table-checksum privilege check fails on MySQL 5.5

pt-table-checksum used to check the user's privileges, but the method was not always reliable, and due to http://bugs.mysql.com/bug.php?id=61846 it became quite unreliable on MySQL 5.5. So the privs check was removed altogether, meaning that the tool may fail later if the user's privileges are insufficient.

* Fixed bug 950294: pt-table-checksum should always create schema and tables wi
th IF NOT EXISTS

In certain cases where the master and replicas have different schemas and/or tables, pt-table-checksum could break replication because the checksums table did not exist on a replica.

* Fixed bug 821703: pt-query-digest --processlist may crash
* Fixed bug 883098: pt-query-digest crashes if processlist has extra columns

Certain distributions of MySQL add extra columns to SHOW PROCESSLIST which caused pt-query-digest --processlist to crash at times.

* Fixed bug 941469: pt-kill doesn't reconnect if its connection is lost

pt-kill is meant to be a long-running daemon, so naturally it's important that it stays connected to MySQL.

* Fixed bug 1004567: pt-heartbeat --update --replace causes duplicate key error

The combination of these pt-heartbeat options could cause replication to break due to a duplicate key error.

* Fixed bug 1022628: pt-online-schema-change error: Use of uninitialized value
in numeric lt (<) at line 6519

This bug was related to how --quiet was handled, and it could happen even if --quiet wasn't given on the command line.

All in all, this is solid bug fix release, and 2.1 users are encouraged to upgrade.
