Percona Toolkit 2.2.12 发布了，Percona Toolkit 是一组高级的命令行工具，用来管理 MySQL 和系统任务。 改进内容包括： New Features: pt-stalk now gathers dmesg output from up to 60 seconds before the triggering event. Bugs Fixed: Fixed bug 1376561: pt-archiver was not able to archive all the rows when a table had a hash partition. Fixed by implementing support for tables which have primary or unique indexes. Fixed bug 1217466: pt-table-checksum would refuses to run on Percona XtraDB Cluster if server_id was the same on all nodes. Fixed by using the wsrep_node_incoming_address as a unique identifier for cluster nodes, instead of relying on server_id. Fixed bug 1269695: pt-online-schema-change documentation now contains more information about limitations on why it isn’t running ALTER TABLE for a table which has only a non-unique index. Fixed bug 1328686: Running pt-hearbeat with --check-read-only option would cause an error when running on server with read_only option. Tool now waits for server read_only status to be disabled before starting to run. Fixed bug 1373937: pt-table-checksum now supports none as valid --recursion-method when using with Percona XtraDB Cluster. Fixed bug 1377888: Documentation was stating that pt-query-digest is able to parse a raw binary log file, while it can only parse a file which was decoded with mysqlbinlog tool before. Fixed by improving the documentation and adding a check for binary file and providing a relevant error message. 详情请看 release notes 和 2.2.12 milestone at Launchpad.
