Changes 5.6.19:

Functionality Added or Changed

The obsolete and unmaintained charset2html utility has been removed from MySQL distributions.

The mysqlbug, mysql_waitpid, and mysql_zap utilities have been deprecated and will be removed in MySQL 5.7.

Bugs Fixed

InnoDB: After upgrading from 5.6.10 to MySQL versions up to and including MySQL 5.6.18, InnoDB would attempt to rename obsolete full-text search auxiliary tables on server startup, resulting in an assertion failure.

InnoDB: For each insert, memset would be called three times to allocate memory for system fields. To reduce CPU usage, the three memset calls are now combined into a single call.

InnoDB: Enabling the InnoDB Table Monitor would result in a ib_table->stat_initialized assertion failure.

InnoDB: Setting innodb_max_dirty_pages_pct=0 would leave 1% of dirty pages unflushed. Buffer pool flushing is initiated when the percentage of dirty pages is greater innodb_max_dirty_pages_pct. The internal variables that store the innodb_max_dirty_pages_pct value and the percentage of dirty pages (buf_get_modified_ratio_pct and srv_max_buf_pool_modified_pct) were defined as unsigned integer data types, which meant that a innodb_max_dirty_pages_pct value of 0 required a dirty pages percentage of 1 or greater to initiate buffer pool flushing.

To address this problem, the buf_get_modified_ratio_pct and srv_max_buf_pool_modified_pct internal variables are redefined as double data types, which changes the range value for innodb_max_dirty_pages_pct and innodb_max_dirty_pages_pct_lwm from 0 .. 99 to 0 .. 99.99. Additionally, buffer pool flushing is now initiated when the percentage of dirty pages is “greater than or equal to” innodb_max_dirty_pages_pct.

Replication: Log rotation events could cause group_relay_log_pos to be moved forward incorrectly within a group. This meant that, when the transaction was retried, or if the SQL thread was stopped in the middle of a transaction following one or more log rotations (such that the transaction or group spanned multiple relay log files), part or all of the group was silently skipped.

This issue has been addressed by correcting a problem in the logic used to avoid touching the coordinates of the SQL thread when updating the log position as part of a relay log rotation whereby it was possible to update the SQL thread's coordinates when not using a multi-threaded slave, even in the middle of a group.

Replication: When running the server with --gtid-mode=ON, STOP SLAVE followed by START SLAVE resulted in a mismatch between the information provided by INFORMATION_SCHEMA.INNODB_TEMP_TABLE_INFO and the Slave_open_temp_tables status variable: the INNODB_TEMP_TABLE_INFO table showed that no temporary tables existed, but Slave_open_temp_tables had a nonzero value.

Replication: In certain cases, the server mishandled triggers and stored procedures that tried to modify other tables when called by CREATE TABLE ... SELECT. This is now handled correctly as an error.

Replication: When used on a table employing a transactional storage engine, a failed TRUNCATE TABLE was still written to the binary log and thus replayed on the slave. This could lead to inconsistency when the master retained data that was removed on the slave.

Now in such cases TRUNCATE TABLE is logged only when it executes successfully.

Replication: The server did not always handle the auto.cnf file correctly in cases where this file's permissions were incorrect.

Replication: When the binary log was rotated due to receipt of a SIGHUP signal, the new binary log did not contain the Previous_gtid_event required for subsequent processing of that binary log's GTID events. Now when SIGHUP is received, steps are taken to insure that the server writes the necessary Previous_gtid_event to the new log before writing any GTID events to the new log.
