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.
