What's new in MySQL 5.5.11
MySQL 5.5.11 contains the following bugs fixes:
- Partitioning: A problem with a previous fix for poor performance of INSERT ON DUPLICATE KEY UPDATE statements on tables having many partitions caused the handler function for reading a row from a specific index to fail to store the ID of the partition last used. This caused some statements to fail with Can't find record errors.
- An assertion was raised if an XA COMMIT was issued when an XA transaction had already encountered an error (such as a deadlock) that required the transaction to be rolled back.
- On some systems, debug builds of comp_err.c could fail due to an uninitialized variable.
- The server read one byte too many when trying to process an XML string lacking a closing quote (') or double quote (") character used as an argument for UpdateXML() or ExtractValue().
- Attempting to create a spatial index on a CHAR column longer than 31 bytes led to an assertion failure if the server was compiled with safemutex support.
- Aggregation followed by a subquery could produce an incorrect result.
- An incorrect character set pointer passed to my_strtoll10_mb2() caused an assertion to be raised.
- mysqldump did not quote database names in ALTER DATABASE statements in its output, which could cause an error at reload time for database names containing a dash.
- The MYSQL_HOME environment variable was being ignored.
