Bugs Fixed:
[LIST]
[]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).
