FOR would crash the server if it could not execute the due to: 1) if the was Read-Write in a Read-Only transaction (bug #1387951), 2) if the needed to re-open an already open temporary table and would fail to do so (bug #1412423), 3) if the needed to commit implicitly the ongoing transaction and the implicit commit would fail (bug #1418049).

Percona 为 MySQL 数据库服务器进行了改进，在功能和性能上较 MySQL 有着很显著的提升。该版本提升了在高负载情况下的 InnoDB 的性能、为 DBA 提供一些非常有用的性能诊断工具；另外有更多的参数和命令来控制服务器行为。 Percona Server 只包含 MySQL 的服务器版，并没有提供相应对 MySQL 的 Connector 和 GUI 工具进行改进。 Percona Server 使用了一些 google-mysql-tools, Proven Scaling, Open Query 对 MySQL 进行改造。 |
