Alterações na distribuição 3.23.12 (07 Mar 2000)

Fixed bug in MyISAM involving REPLACE ... SELECT ... which could give a corrupted table.

• Fixed bug in myisamchk where it incorrectly reset the AUTO_INCREMENT value.
• LOTS of patches for Linux Alpha. MariaDB now appears to be relatively stable on Alpha.
• Changed DISTINCT on HEAP temporary tables to use hashed keys to quickly find duplicated rows. This mostly concerns queries of type SELECT DISTINCT ... GROUP BY .... This fixes a problem where not all duplicates were removed in queries of the above type. In addition, the new code is MUCH faster.
• Added patches to make MariaDB compile on Mac OS X.
• Added IF NOT EXISTS clause to CREATE DATABASE.
• Added --all-databases and --databases options to mysqldump to allow dumping of many databases at the same time.
• Fixed bug in compressed DECIMAL() index in MyISAM tables.
• Fixed bug when storing 0 into a timestamp.
• When doing mysqladmin shutdown on a local connection, mysqladmin now waits until the PID file is gone before terminating.
• Fixed core dump with some COUNT(DISTINCT ...) queries.
• Fixed that myisamchk works properly with RAID tables.
• Fixed problem with LEFT JOIN and key_field IS NULL.
• Fixed bug in net_clear() which could give the error Aborted connection in the MariaDB clients.
• Added options USE INDEX (key_list) and IGNORE INDEX (key_list) as parameters in SELECT.
• DELETE and RENAME should now work on RAID tables.
