Subject: MySQL 3.23.33 released

This release mainly fixes some bugs in replication. If you are not using replication you probably don't have any reasons to upgrade.

Changes in release 3.23.33

• Added `--character-sets-dir' to `myisampack'.
• Removed warnings when running `REPAIR TABLE .. EXTENDED'.
• Fixed core-dump bug when using `GROUP BY' on an alias, where the alias was the same as an existing column name.
• Added `SEQUENCE()' as an example UDF function.
• Changed `mysql_install_db' to use `BINARY' for `CHAR' columns in the privilege tables.
• Changed `TRUNCATE table_name' to `TRUNCATE TABLE table_name' to use the same syntax as Oracle. Until 4.0 we will also allow `TRUNCATE table_name' to not crash old code.
• Fixed 'no found rows' bug in `MyISAM' tables when a `BLOB' was first part of a multi-part key.
• Fixed bug where `CASE' didn't work with `GROUP BY'.
• Added option `--sort-recover' to `myisamchk'.
• `myisamchk -S' and `OPTIMIZE TABLE' now work on Windows.
• Fixed bug when using `DISTINCT' on results from functions that referred to a group function, like `SELECT a,DISTINCT SEC_TO_TIME(sum(a)) from table_name GROUP BY a,b'.
• Fixed buffer overrun in `libmysqlclient' library. Fixed bug in handling `STOP' event after `ROTATE' event in replication.
• Fixed another buffer overrun in `DROP DATABASE'.
• Added `Table_locks_immediate' and `Table_locks_waited' status variables.
• Fixed bug in replication that broke slave server start with existing `master.info'. This fixes a bug introduced in 3.23.32.
• Added `SET SQL_SLAVE_SKIP_COUNTER=n' command to recover from replication glitches without a full database copy.
• Added `max_binlog_size' variable; the binary log will be rotated automatically when the size crosses the limit.
• Added `Last_error', `Last_errno', and `Slave_skip_counter' to `SHOW SLAVE STATUS'.
• Fixed bug in `MASTER_POS_WAIT()' function.
• Execute coredump handler on `SIGILL', and `SIGBUS' in addition to `SIGSEGV'.
• On x86 Linux, print the current query and thread (connection) id, if available, in the coredump handler.
• Fixed several timing bugs in the test suite.
• Extended `mysqltest' to take care of the timing issues in the test suite.
• `ALTER TABLE' can now be used to change the definition for a `MERGE' table.
• Fixed creation of `MERGE' tables on Windows.
• Portability fixes for OpenBSD and OS2.
• Added -temp-pool option to mysqld. Using this option will cause most temporary files created to use a small set of names, rather than a unique name for each new file. This is to work around a problem in the Linux kernel dealing with creating a bunch of new files with different names. With the old behavior, Linux seems to "leak" memory, as it's being allocated to the directory entry cache instead of the disk cache.
