[Maria-developers] COT() function
by Ian Gilfillan 03 Aug '13

03 Aug '13

Hi SELECT COT(0) returns: ERROR 1690 (22003): DOUBLE value is out of range in 'cot(0)' in both MariaDB 10 and 5.5, but in MySQL 5.1 it returns NULL. I can't find a changelog reference to this, but I see it's still documented as returning NULL in MySQL 5.5 (I don't have this to test on). Is this a MariaDB-specific change? When did this change in behaviour happen? thanks, ian

[Maria-developers] Please review: [Commits] Rev 3797: MDEV-4816: rpl.rpl_trunc_temp fails in 10.0-serg in file:///data0/psergey/dev2/10.0-serg/

Hi Kristian, In order to get rid of test failures of 10.0-serg, I have pushed the below patch. It seems to have the right effect, but I have no confidence about this patch being achitecturally correct, etc. Could you please review this and/or make another fix for the problem? ----- Forwarded message from Sergey Petrunya <psergey(a)askmonty.org> ----- From: Sergey Petrunya <psergey(a)askmonty.org> To: commits(a)mariadb.org X-Mailer: mail (GNU Mailutils 2.2) Date: Fri, 2 Aug 2013 18:12:11 +0400 (MSK) Subject: [Commits] Rev 3797: MDEV-4816: rpl.rpl_trunc_temp fails in 10.0-serg in file:///data0/psergey/dev2/10.0-serg/ At file:///data0/psergey/dev2/10.0-serg/ ------------------------------------------------------------ revno: 3797 revision-id: psergey(a)askmonty.org-20130802141209-4dqfvx2db8acxwbl parent: svoj(a)mariadb.org-20130729140849-dciz5ffq25ciip6q committer: Sergey Petrunya <psergey(a)askmonty.org> branch nick: 10.0-serg timestamp: Fri 2013-08-02 18:12:09 +0400 message: MDEV-4816: rpl.rpl_trunc_temp fails in 10.0-serg Temorary fix for a number of replication tests (rpl.rpl_temp_table_mix_row rpl.rpl_trunc_temp rpl.rpl_current_user rpl.rpl_gtid_master_promote): - THD::decide_logging_format() should not assume that mysql.gtid_slave_pos is a non-replicated table.
