Percona Server 5.5.52-38.3 发布

Percona Server 5.5.52-38.3 发布了，该版本基于 MySQL 5.5.52，包含了所有的 bug 修复，是Percona Server 5.5 系列中的正式版本。该版本主要是修复bug，主要更新如下：

Bugs 修复：

• mysql_upgrade now does not binlog its actions by default. To restore the previous behavior, use--write-binlog option. Bug fixed #1065841(upstream #56155).

• After fixing bug #1540338, system table engine validation check is no longer skipped for tables that don’t have an explicit ENGINE clause in the CREATE TABLE statement. If MySQL upgrade statements are replicated, and the slave does not have the MyISAM set as a default storage engine, then the CREATE TABLE mysql.server statement would attempt to create an InnoDB table and fail becausemysql_system_tables.sql script omitted explicit engine setting for this table. Bug fixed #1600056.

• Audit Log Plugin would hang when trying to write a log record of audit_log_buffer_size length. Bug fixed#1588439.

• Audit Log Plugin malformed record could be written after audit_log_flush was set to ON in ASYNC andPERFORMANCE modes. Bug fixed #1613650.

• INFORMATION_SCHEMA.TABLES (or other schema info table) table query running in parallel withINFORMATION_SCHEMA.GLOBAL_TEMPORARY_TABLES query may result in TABLES-query thread context having a mutex locked twice, or unlocked twice, or left locked, resulting in crashes or hangs. Bug fixed #1614849.

Other bugs fixed: #1626002 (upstream #83073), #904714, #1098718, #1610102, #1610110, #1613663, #1613728, #1613986,#1614885, #1615959, #1616091, #1616753, #1616768, #1616937, #1617150, #1617323, #1618478, #1618718, #1618811, #1618819,#1619547, #1619572, #1619665, #1620200, #1626458, #1626500, and #1628417
