Alterações na distribuição 3.23.52 (14 Aug 2002)

Wrap BEGIN/COMMIT around transaction in the binary log. This makes replication honour transactions.

• Fixed security bug when having an empty database name in the user.db table.
• Changed initialisation of RND() to make it less predicatable.
• Fixed problem with GROUP BY on result with expression that created a BLOB field.
• Fixed problem with GROUP BY on columns that have NULL values. To solve this we now create an MyISAM temporary table when doing a GROUP BY on a possible NULL item. From MariaDB 4.0.5 we can use in memory HEAP tables for this case.
• Fixed problem with privilege tables when downgrading from 4.0.2 to 3.23.
• Fixed thread bug in SLAVE START, SLAVE STOP and automatic repair of MyISAM tables that could cause table cache to be corrupted.
• Fixed possible thread related key-cache-corruption problem with OPTIMIZE TABLE and REPAIR TABLE.
• Added name of 'administrator command' logs.
• Fixed bug with creating an auto-increment value on second part of a UNIQUE() key where first part could contain NULL values.
• Don't write slave-timeout reconnects to the error log.
• Fixed bug with slave net read timeouting
• Fixed a core-dump bug with MERGE tables and MAX() function.
• Fixed bug in ALTER TABLE with BDB tables.
• Fixed bug when logging LOAD DATA INFILE to binary log with no active database.
• Fixed a bug in range optimiser (causing crashes).
• Fixed possible problem in replication when doing DROP DATABASE on a database with InnoDB tables.
• Fixed that mysql_info() returns 0 for 'Duplicates' when using INSERT DELAYED IGNORE.
• Added -DHAVE_BROKEN_REALPATH to the Mac OS X (darwin) compile options in configure.in to fix a failure under high load.
