Alterações na distribuição 3.23.26 (18 Oct 2000)

Renamed FLUSH MASTER and FLUSH SLAVE to RESET MASTER and RESET SLAVE.

• Fixed <> to work properly with NULL.
• Fixed a problem with SUBSTRING_INDEX() and REPLACE(). (Patch by Alexander Igonitchev)
• Fix CREATE TEMPORARY TABLE IF NOT EXISTS not to produce an error if the table exists.
• If you don't create a PRIMARY KEY in a BDB table, a hidden PRIMARY KEY will be created.
• Added read-only-key optimization to BDB tables.
• LEFT JOIN in some cases preferred a full table scan when there was no WHERE clause.
• When using --log-slow-queries, don't count the time waiting for a lock.
• Fixed bug in lock code on Windows which could cause the key cache to report that the key file was crashed even if it was okay.
• Automatic repair of MyISAM tables if you start mysqld with --myisam-recover.
• Removed the TYPE= keyword from CHECK and REPAIR. Allow CHECK options to be combined. (You can still use TYPE=, but this usage is deprecated.)
• Fixed mutex bug in the binary replication log --- long update queries could be read only in part by the slave if it did it at the wrong time, which was not fatal, but resulted in a performance-degrading reconnect and a scary message in the error log.
• Changed the format of the binary log --- added magic number, server version, binlog version. Added server ID and query error code for each query event.
• Replication thread from the slave now will kill all the stale threads from the same server.
• Long replication user names were not being handled properly.
• Added --replicate-rewrite-db option to mysqld.
• Added --skip-slave-start option to mysqld.
• Updates that generated an error code (such as INSERT INTO foo(some_key) values (1),(1)) erroneously terminated the slave thread.
• Added optimization of queries where DISTINCT is only used on columns from some of the tables.
• Allow floating-point numbers where there is no sign after the exponent (like 1e1).
• SHOW GRANTS didn't always show all column grants.
• Added --default-extra-file=# option to all MariaDB clients.
• Columns referenced in INSERT statements now are initialised properly.
• UPDATE didn't always work when used with a range on a timestamp that was part of the key that was used to find rows.
• Fixed a bug in FULLTEXT index when inserting a NULL column.
• Changed to use mkstemp() instead of tempnam(). Based on a patch from John Jones.
