Percona Server for MySQL 5.7.18-16 已发布,该版本基于 MySQL 5.7.18,并包括其中的所有错误修复。

Percona Server for MySQL 5.7.18-16 是 Percona Server for MySQL 5.7 系列中当前的 GA 版本。更新内容:


  • Percona Server for MySQL 现在可在 Debian 9 (stretch) 上使用,不过现在仅支持 amd64 架构的平台

  • Percona Server for MySQL 现在可以在 OpenSSL 1.1 的支持下构建

  • MyRocks 存储引擎已合并到 Percona Server

  • TokuDB 可杀死正在等待 FT locktre 锁的查询

  • TokuDB enables using the MySQL DEBUG_SYNC facility within Percona FT.

Bug 修复:

  • Row counts in TokuDB could be lost intermittently after restarts. Bug fixed #2.

  • In TokuDB, two races in the fractal tree lock manager could significantly affect transactional throughput for some applications that used a small number of concurrent transactions. These races manifested as transactions unnecessarily waiting for an available lock. Bug fixed #3.

  • Percona FT could assert when opening a dictionary with no useful information to an error log. Bug fixed #23.

  • Percona FT could assert for various reasons deserializing nodes with no useful error output. Bug fixed #24.

  • It was not possible to build Percona Server on Debian 9 (stretch) due to issues with OpenSSL 1.1. Bug fixed #1702903 (upstream #83814).

  • Packaging was using the dpkg --verify command which is not available on wheezy/precise. Bug fixed #1694907.

  • Enabling and disabling the slow query log rotation spuriously added the version suffix to the next slow query log file name. Bug fixed #1704056.

  • With two client connections to a server (debug server build), the server could crash after one of the clients set the global option userstat and flushed the client statistics (FLUSH CLIENT_STATISTICS) and then both clients were closed. Bug fixed #1661488.

  • Percona FT did not pass cmake flags on to snappy cmake. Bug fixed #41. The progress status for partitioned TokuDB table ALTERs was misleading. Bug fixed #42.

  • When a client application is connecting to the Aurora cluster end point using SSL (--ssl-verify-server-cert or --ssl-mode=VERIFY_IDENTITY option), wildcard and SAN enabled SSL certificates were ignored. Note that the --ssl-verify-server-cert option is deprecated in Percona Server 5.7. Bug fixed #1673656 (upstream #68052).

  • Killing a stored procedure execution could result in an assert failure on a debug server build. Bug fixed #1689736 (upstream #86260).

  • The SET STATEMENT .. FOR statement changed the global instead of the session value of a variable if the statement occurred immediately after the SET GLOBAL or SHOW GLOBAL STATUS command. Bug fixed #1385352.

  • When running SHOW ENGINE INNODB STATUS, the Buffer pool size, bytes entry contained 0. BUg fixed #1586262.

  • The synchronization between the LRU manager and page cleaner threads was not done at shutdown. Bug fixed #1689552.

  • Spurious lock_wait_timeout_thread wakeup in lock_wait_suspend_thread() could occur. Bug fixed #1704267 (upstream #72123).

其他 bug 修复:

#1686603#6#44#65#1160986#1686934#1688319#1689989#1690012#1691682#1697700#1699788#1121072, and #1684601 (upstream #86016).
