Percona Server 5.6.35-80.0 发布了,该版本基于mysql 5.6.35 ,并包括其中的所有错误修复。

作为 MySQL 的最新替代、衍生版本,Percona Server 是开源的和免费的。

更新内容:

新特性:

Kill Idle Transactions 功能已通过设置连接套接字读取超时值而不是定期扫描内部InnoDB事务列表来重新实现。这使得该功能适用于任何事务存储引擎,如TokuDB,以及未来的MyRocks。 这种重新实现还解决了一些现有的错误,包括服务器崩溃: #1166744 , #1179136 , #907719 和 #1369373 。

Bugs 修复:

Logical row counts for TokuDB tables could get inaccurate over time.

Repeated execution of SET STATEMENT ... FOR SELECT FROM view could lead to a server crash.

CREATE TEMPORARY TABLE would create a transaction in binary log on a read-only server.

If temporary tables from CREATE TABLE ... AS SELECT contained compressed attributes it could lead to a server crash.

Using the per-query variable statement with subquery temporary tables could cause a memory leak.

Fixed new compilation warnings with GCC 6.

A server could crash if a bitmap write I/O error happens in the background log tracking thread while a FLUSH CHANGED_PAGE_BITMAPS is executing concurrently.

TokuDB was using the wrong function to calculate free space in data files.

CONCURRENT_CONNECTIONS column in the USER_STATISTICS table was showing incorrect values.

InnoDB index dives did not detect some of the concurrent tree changes, which could return bogus estimates.

INFORMATION_SCHEMA.INNODB_CHANGED_PAGES queries would needlessly read potentially incomplete bitmap data past the needed LSN range.

Percona Server cmake compiler would always attempt to build RocksDB even if -DWITHOUT_ROCKSDB=1 argument was specified.

Adding COMPRESSED attributes to InnoDB special tables fields (like mysql.innodb_index_stats and mysql.innodb_table_stats ) could lead to server crashes.

Lack of free pages in the buffer pool is not diagnosed with innodb_empty_free_list_algorithm set to backoff (which is the default).

mysqld_safe now limits the use of rm and chown to avoid privilege escalation. chown can now be used only for /var/log directory.

Renaming a TokuDB table to a non-existent database with tokudb_dir_per_db enabled would lead to a server crash.

Read Free Replication optimization could not be used for TokuDB partition tables.
