Percona Toolkit 3.0.13 发布，MySQL 管理工具包

Percona Toolkit 3.0.13 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。

Bug 修复:

• PT-1673 :  pt-show-grants was incompatible with MariaDB 10+ (thanks  Tim Birkett )

• PT-1638 :  pt-online-schema-change was erroneously taking MariaDB 10.x for MySQL 8.0 and rejecting to work with it to avoid the upstream bug  #89441 scope.

• PT-1616 :  pt-table-checksum failed to resume on large tables with binary strings containing invalid UTF-8 characters.

• PT-1573 :  pt-query-digest didn’t work in case of  log_timestamps = SYSTEM my.cnf option.

• PT-157 : Specifying a non-primary key index with the ‘i’ part of the  --source argument made  pt-archiver to ignore the  --primary-key-only option presence.

优化提升:

• PT-1340 :  pt-stalk now doesn’t call  mysqladmin debug command by default to avoid flooding in the error log.  CMD_MYSQLADMIN="mysqladmin debug" environment variable reverts  pt-stalk to the previous way of operation.

• PT-1637 : A new  --fail-on-stopped-replication option  allows  pt-table-checksum to detect failing slave nodes.
