Percona Toolkit 2.2.12 发布，MySQL 管理工具

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.
