Subject: MySQL 3.23.29 released


We have now released MySQL 3.23.29.

Because of a error in 'make install' which we discovered real late,
the binaries (which where not affected by this error) have version
3.23.29 and the source has version 3.23.29a; The main change for
3.23.29a is that 'make install' doesn't complain about a missing file
and that configure works better on Solaris 2.8.

This version includes mainly a lot of bug fixes for BDB tables
and some critical bug fixes for replication.

We will now start running our benchmark test with BDB tables with
different options and when we are satisfied that everything works ok,
we will build a MySQL 3.23 binary with support for BDB tables.

As 3.23.x series seems to be relatively stable (except BDB tables and
replication which is still in development) , we expect that we can
drop the -gamma prefix soon.

Changes in release 3.23.29

   * Configure updates for Tru64, large file support and better TCP
     wrappers 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 not used 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 *MySQL* 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'

   * 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 variable `bdb_lock_max' to `bdb_max_lock'.

   * Added support for `auto_increment' on sub fields for BDB tables.

   * Added `ANALYZE' of BDB tables.

   * Store in BDB tables the number of rows; This helps to optimize
     queries when we need an approximation of the number of row.

   * If we get an error in a multi-row statement, we now only rollback
     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 option `--bdb-shared-data' to `mysqld'.

   * Added status variable `Slave_open_temp_tables'.

   * Added variables `binlog_cache_size' and `max_binlog_cache_size' to

     are now transaction endpoints.

   * If you do a `DROP DATABASE' on a symbolic linked database, both
     the link and the original database is deleted.

   * Fixed that `DROP DATABASE' works 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 or not key is `FULLTEXT'.

   * New script `mysqld_multi'. *Note mysqld_multi::.

   * 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 OS2 by `Yuri Dario'.

   * `FLUSH TABLES table_name' didn't always flush the index tree
     properly to disk.

   * `--bootstrap' is now run in a separate thread. This fixes the
     problem that `mysql_install_db' core dumped on some Linux machines.

   * Changed `mi_create()' to use less stack.

   * Fixed bug with optimizer trying to over-optimize `MATCH' when used
     with `UNIQUE' key.

   * Changed `crash-me' and the *MySQL* benchmarks to also work with

   * Allow `RESTRICT' and `CASCADE' after `DROP TABLE' to make porting

   * Reset status variable which could cause problem if one used

   * Added variable `connect_timeout' to `mysql' and `mysqladmin'.

   * Added `connect_timeout' as an alias for `timeout' for option files
     read by `mysql_options()'.
