End of Product Lifecycle. Active development and support for MySQL Database Server versions 3.23, 4.0, and 4.1 has ended. For details, see http://www.mysql.com/about/legal/lifecycle/#calendar. Please consider upgrading to a recent version. Further updates to the content of this manual will be minimal. All formats of this manual will continue to be available until 31 Dec 2010.
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()
shortens the result
string if it is 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
multiple-part keys where you 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
file.
Fixed a bug in the host name cache which caused
mysqld to report the host name 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
value 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 TABLE
of
BDB
tables.
In BDB
tables, we now store the number of
rows; this helps to optimize queries when we need an
approximation of the number of rows.
If we get an error in a multiple-row statement, we now only roll back the last statement, not the entire transaction.
If you do a
ROLLBACK
when you have updated a nontransactional table you 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 are 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. See Section 4.3.4, “mysqld_multi — Manage Multiple MySQL Servers”.
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
my_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
TABLE
/OPTIMIZE TABLE
.
Applied patches for OS/2 by Yuri Dario
.
FLUSH TABLES
didn't always
flush the index tree to disk properly.
tbl_name
--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 optimizer trying to over-optimize
MATCH()
when used with
UNIQUE
key.
Changed crash-me
and the MySQL 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
--log-slow-queries
.
Added connect_timeout
variable to mysql and
mysqladmin.
Added connect-timeout
as an alias for
timeout
for option files read by
mysql_options()
.
