MySQL 5.0 Release Notes  /  Changes in MySQL Enterprise 5.0.64 [MRU] (2008-06-10)

Changes in MySQL Enterprise 5.0.64 [MRU] (2008-06-10)

This is a Monthly Rapid Update release of the MySQL Enterprise Server 5.0.

This section documents all changes and bugfixes that have been applied since the last MySQL Enterprise Server release (5.0.62). If you would like to receive more fine-grained and personalized update alerts about fixes that are relevant to the version and features you use, please consider subscribing to MySQL Enterprise (a commercial MySQL offering). For more details please see

Functionality Added or Changed

  • Incompatible Change; Important Change: The FEDERATED storage engine is now disabled by default in the .cnf files shipped with MySQL distributions (my-huge.cnf, my-medium.cnf, and so forth). This affects server behavior only if you install one of these files. (Bug #37069)

Bugs Fixed

  • Replication: CREATE PROCEDURE and CREATE FUNCTION statements containing extended comments were not written to the binary log correctly, causing parse errors on the slave. (Bug #36570)

    References: See also Bug #32575.

  • On Windows 64-bit systems, temporary variables of long types were used to store ulong values, causing key cache initialization to receive distorted parameters. The effect was that setting key_buffer_size to values of 2GB or more caused memory exhaustion to due allocation of too much memory. (Bug #36705)

  • Multiple-table UPDATE statements that used a temporary table could fail to update all qualifying rows or fail with a spurious duplicate-key error. (Bug #36676)

  • A REGEXP match could return incorrect rows when the previous row matched the expression and used CONCAT() with an empty string. (Bug #36488)

  • For EXPLAIN EXTENDED, execution of an uncorrelated IN subquery caused a crash if the subquery required a temporary table for its execution. (Bug #36011)
