Can't repeat this anymore. [msvensson@neptunus mysql-test]$ ./mysql-test-run.pl --start-and-exit --tmpdir=/tmp/x [msvensson@neptunus ~]$ ls /tmp/x master.sock [msvensson@neptunus mysql-test]$ ../client/mysql --socket=/tmp/x/master.sock -uroot mysql> use test mysql> create temporary table kntest (a varchar(100)); [msvensson@neptunus ~]$ ls /tmp/x @0023sql4910_1_0.frm @0023sql4910_1_0.MYD @0023sql4910_1_0.MYI master.sock Same result with heap and innodb tables.

Yes, I verified that the bug is indeed present in 5.1.3 and 5.1.4 (as downloaded from dev.mysql.com), but gone in 5.1.5.

Pushed to 5.1.6 a fix to make "CREATE TEMPORARY TABLE LIKE" put the temp table in the same place as "CREATE TEMPORARY TABLE".

Specifying a value for <literal>--tmptable</literal> without a

Description: The --tmpdir option changed behaviour in 5.1.4 (and possibly in 5.1.3, haven't checked). I *think* the change happened in or shortly after the push of the TDC changesets, not 100% sure though. The new behaviour is not present in 5.0. Now, the --tmpdir option requires a trailing slash '/' to work the way I would expect it to: * --tmpdir=/tmp/x/ -> temporary tables created inside directory /tmp/x/. * --tmpdir=/tmp/x -> temporary tables created in /tmp, with names prefixed with x (eg. /tmp/x#sql4eb3_1_0.frm). If this is the expected behaviour, it should be clearly documented in the description of the --tmpdir command line option. How to repeat: Here is a simple way to start the server with --tmpdir: cd mysql-test ./mysql-test-run.pl --start-and-exit --tmpdir=/tmp/x alias ../client/mysql --socket=/tmp/x/master.sock -uroot use test create temporary table kntest (a varchar(100)); # Don't exit the mysql client, as that will delete the temporary table Now the directory /tmp will contain the temporary table files named /tmp/x#...
