This is a bugfix release for the current stable tree. Users who use MySQL
in an untrusted multi-user environment should consider upgrading to this
version, which also fixes a bug that enabled valid local users to crash
mysqld by using a specially modified mysql client application.



D.3.2 Changes in release 3.23.55 (23 Jan 2003)

- Fixed double free'd pointer bug in mysql_change_user() handling, that enabled a specially hacked version of MySQL client to crash mysqld. Note, that one needs to login to the server by using a valid user account to be able to exploit this bug.
- Fixed bug with the --slow-log when logging an administrator command (like FLUSH TABLES).
- Fixed bug in GROUP BY when used on BLOB column with NULL values.
- Fixed a bug in handling NULLs in CASE ... WHEN ....
- Bugfix for --chroot (see section D.3.3 Changes in release 3.23.54 (05 Dec 2002)) is reverted. Unfortunately, there is no way to make it to work, without introducing backward-incompatible changes in `my.cnf'. Those who need --chroot functionality, should upgrade to MySQL 4.0. (The fix in the 4.0 branch did not break backward-compatibility).
- Make --lower-case-table-names default on MacOSX as the file system is case insensitive.
- Fixed a bug in `scripts/mysqld_safe.sh' in NOHUP_NICENESS testing.
- Transactions in AUTOCOMMIT=0 mode didn't rotate binary log.
- Fixed a bug in scripts/make_binary_distribution that resulted in a remaining @HOSTNAME@ variable instead of replacing it with the correct path to the hostname binary.
- Fixed a very unlikely bug that could cause SHOW PROCESSLIST to core dump in pthread_mutex_unlock() if a new thread was connecting.
- Forbid SLAVE STOP if the thread executing the query has locked tables. This removes a possible deadlock situation.
