Alterações na distribuição 3.23.15 (May 2000: Beta)

To start mysqld as root, you must now use the --user=root option.

• Added interface to Berkeley DB. (This is not yet functional; play with it at your own risk!)
• Replication between master and slaves.
• Fixed bug that other threads could steal a lock when a thread had a lock on a table and did a FLUSH TABLES command.
• Added the slow_launch_time variable and the Slow_launch_threads status variable to mysqld. These can be examined with mysqladmin variables and mysqladmin extended-status.
• Added functions INET_NTOA() and INET_ATON().
• The default type of IF() now depends on the second and third arguments and not only on the second argument.
• Fixed case when myisamchk could go into a loop when trying to repair a crashed table.
• Don't write INSERT DELAYED to update log if SQL_LOG_UPDATE=0.
• Fixed problem with REPLACE on HEAP tables.
• Added possible character sets and time zone to SHOW VARIABLES output.
• Fixed bug in locking code that could result in locking problems with concurrent inserts under high load.
• Fixed a problem with DELETE of many rows on a table with compressed keys where MariaDB scanned the index to find the rows.
• Fixed problem with CHECK on table with deleted keyblocks.
• Fixed a bug in reconnect (at the client side) where it didn't free memory properly in some contexts.
• Fixed problems in update log when using LAST_INSERT_ID() to update a table with an AUTO_INCREMENT key.
• Added NULLIF() function.
• Fixed bug when using LOAD DATA INFILE on a table with BLOB/TEXT columns.
• Optimized MyISAM to be faster when inserting keys in sorted order.
• EXPLAIN SELECT ... now also prints out whether MariaDB needs to create a temporary table or use file sorting when resolving the SELECT.
• Added optimization to skip ORDER BY parts where the part is a constant expression in the WHERE part. Indexes can now be used even if the ORDER BY doesn't match the index exactly, as long as all the unused index parts and all the extra ORDER BY columns are constants in the WHERE clause. Leia "Como o MariaDB Utiliza Índices".
• UPDATE and DELETE on a whole unique key in the WHERE part are now faster than before.
• Changed RAID_CHUNKSIZE to be in 1024-byte increments.
• Fixed core dump in LOAD_FILE(NULL).
