Alterações na distribuição 3.23.29 (16 Dec 2000)

Configure updates for Tru64, large file support, and better TCP wrapper support. By Albert Chin-A-Young.

• Fixed bug in <=> operator.
• Fixed bug in REPLACE with BDB tables.
• LPAD() and RPAD() will shorten the result string if it's longer than the length argument.
• Added SHOW LOGS command.
• Remove unused BDB logs on shutdown.
• When creating a table, put PRIMARY keys first, followed by UNIQUE keys.
• Fixed a bug in UPDATE involving multi-part keys where one specified all key parts both in the update and the WHERE part. In this case MariaDB could try to update a record that didn't match the whole WHERE part.
• Changed drop table to first drop the tables and then the .frm file.
• Fixed a bug in the hostname cache which caused mysqld to report the hostname as '' in some error messages.
• Fixed a bug with HEAP type tables; the variable max_heap_table_size wasn't used. Now either MAX_ROWS or max_heap_table_size can be used to limit the size of a HEAP type table.
• Changed the default server-id to 1 for masters and 2 for slaves to make it easier to use the binary log.
• Renamed bdb_lock_max variable to bdb_max_lock.
• Added support for AUTO_INCREMENT on sub-fields for BDB tables.
• Added ANALYZE of BDB tables.
• In BDB tables, we now store the number of rows; this helps to optimise queries when we need an approximation of the number of rows.
• If we get an error in a multi-row statement, we now only roll back the last statement, not the entire transaction.
• If you do a ROLLBACK when you have updated a non-transactional table you will get an error as a warning.
• Added --bdb-shared-data option to mysqld.
• Added Slave_open_temp_tables status variable to mysqld
• Added binlog_cache_size and max_binlog_cache_size variables to mysqld.
• DROP TABLE, RENAME TABLE, CREATE INDEX and DROP INDEX are now transaction endpoints.
• If you do a DROP DATABASE on a symbolically linked database, both the link and the original database is deleted.
• Fixed DROP DATABASE to work on OS/2.
• Fixed bug when doing a SELECT DISTINCT ... table1 LEFT JOIN table2 ... when table2 was empty.
• Added --abort-slave-event-count and --disconnect-slave-event-count options to mysqld for debugging and testing of replication.
• Fixed replication of temporary tables. Handles everything except slave server restart.
• SHOW KEYS now shows whether key is FULLTEXT.
• New script mysqld_multi. Leia "mysqld_multi, programa para gerenciar múltiplos servidores MySQL".
• Added new script, mysql-multi.server.sh. Thanks to Tim Bunce <Tim.Bunce@ig.co.uk> for modifying mysql.server to easily handle hosts running many mysqld processes.
• safe_mysqld, mysql.server, and mysql_install_db have been modified to use mysql_print_defaults instead of various hacks to read the my.cnf files. In addition, the handling of various paths has been made more consistent with how mysqld handles them by default.
• Automatically remove Berkeley DB transaction logs that no longer are in use.
• Fixed bug with several FULLTEXT indexes in one table.
• Added a warning if number of rows changes on REPAIR/OPTIMIZE.
• Applied patches for OS/2 by Yuri Dario.
• FLUSH TABLES tbl_name didn't always flush the index tree to disk properly.
• --bootstrap is now run in a separate thread. This fixes a problem that caused mysql_install_db to core dump on some Linux machines.
• Changed mi_create() to use less stack space.
• Fixed bug with optimiser trying to over-optimise MATCH() when used with UNIQUE key.
• Changed crash-me and the MariaDB benchmarks to also work with FrontBase.
• Allow RESTRICT and CASCADE after DROP TABLE to make porting easier.
• Reset status variable which could cause problem if one used --slow-log.
• Added connect_timeout variable to MariaDB and mysqladmin.
• Added connect-timeout as an alias for timeout for option files read by mysql_options().
