C.1.22. Release Notes for MySQL Enterprise 5.0.72sp1 [QSP] (13 January 2009)

This is a Service Pack 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 (5.0.72).

Functionality added or changed:

  • Previously, index hints did not work for FULLTEXT searches. Now they work as follows:

    For natural language mode searches, index hints are silently ignored. For example, IGNORE INDEX(i) is ignored with no warning and the index is still used.

    For boolean mode searches, index hints are honored. (Bug#38842)

Bugs fixed:

  • MySQL Cluster: Packaging: Packages for MySQL Cluster were missing the libndbclient.so and libndbclient.a files. (Bug#42278)

  • Support for the revision field in .frm files has been removed. This addresses the downgrading problem introduced by the fix for Bug#17823. (Bug#40021)

  • If the operating system is configured to return leap seconds from OS time calls or if the MySQL server uses a time zone definition that has leap seconds, functions such as NOW() could return a value having a time part that ends with :59:60 or :59:61. If such values are inserted into a table, they would be dumped as is by mysqldump but considered invalid when reloaded, leading to backup/restore problems.

    Now leap second values are returned with a time part that ends with :59:59. This means that a function such as NOW() can return the same value for two or three consecutive seconds during the leap second. It remains true that literal temporal values having a time part that ends with :59:60 or :59:61 are considered invalid.

    For additional details about leap-second handling, see Section 9.6.2, “Time Zone Leap Second Support”. (Bug#39920)

  • Queries of the form SELECT ... WHERE string = ANY(...) failed when the server used a single-byte character set and the client used a multi-byte character set. (Bug#34760)
