MySQL Reference Manual for version 4.0.18.
C.6.33 Changes in release 3.21.3
-
Added reverse check lookup of hostnames to get better security.
-
Fixed some possible buffer overflows if filenames that are too long are used.
-
mysqld
doesn't accept hostnames that start with digits followed by a
'.'
, because the hostname may look like an IP number.
-
Added
--skip-networking
option to mysqld
, to allow only socket
connections. (This will not work with MIT-pthreads!)
-
Added check of too long table names for alias.
-
Added check if database name is okay.
-
Added check if too long table names.
-
Removed incorrect
free()
that killed the server on
CREATE DATABASE
or DROP DATABASE
.
-
Changed some
mysqld
-O
options to better names.
-
Added
-O join_cache_size=#
option to mysqld
.
-
Added
-O max_join_size=#
option to mysqld
, to be able to set a
limit how big queries (in this case big = slow) one should be able to handle
without specifying SET SQL_BIG_SELECTS=1
. A # = is about 10
examined records. The default is "unlimited".
-
When comparing a
TIME
, DATE
, DATETIME
or TIMESTAMP
column to a constant, the constant is converted to a time value before
performing the comparison.
This will make it easier to get ODBC (particularly Access97) to work with
the above types. It should also make dates easier to use and the comparisons
should be quicker than before.
-
Applied patch from Jochen Wiedmann that allows
query()
in
mysqlperl
to take a query with \0
in it.
-
Storing a timestamp with a 2-digit year (
YYMMDD
) didn't work.
-
Fix that timestamp wasn't automatically updated if set in an
UPDATE
clause.
-
Now the automatic timestamp field is the FIRST timestamp field.
-
SELECT * INTO OUTFILE
, which didn't correctly if the outfile already
existed.
-
mysql
now shows the thread ID when starting or doing a reconnect.
-
Changed the default sort buffer size from 2M to 1M.
