I believe this is actually MySQL's fault: http://bugs.mysql.com/bug.php?id=45379
The response is: are you sure this is a bug and not just a confusion. options have always been recognised by their shortest non-ambiguous versions. "group=mysql" is actually seen as "group_concat_max_len=mysql". --------------- which is ridiculous -- if there's confusion, then by definition, it's not "non-ambiguous". (I'd appreciate it if folks could add a comment to http://bugs.mysql.com/bug.php?id=45379) ** Bug watch added: MySQL Bug System #45379 http://bugs.mysql.com/bug.php?id=45379 -- group_concat_max_len problem https://bugs.launchpad.net/bugs/371752 You received this bug notification because you are a member of OurDelta- developers, which is the registrant for OurDelta. Status in OurDelta - Builds for MySQL: New Status in Patches for MySQL by Percona: New Bug description: (reported by Sheeri K. Cabral ) I did not know how to file a bug report against a Percona build of MySQL (not xtradb, that has a launchpad page...). If there could be a clear place on the Percona Labs page, or the documentation page at http://www.percona.com/docs/wiki/patches:start, that would be helpful. Anyway, here's the bug. group_concat_max_len for some reason isn't set properly, even when it's explicitly set in the /etc/my.cnf (the default is 1024, and we get these errors no matter what we set the group_concat_max_len value in /etc/my.cnf to): Version: '5.1.33-percona-log' socket: '/mysql/data/mysql.sock' port: 3306 MySQL Community Server (GPL) 090504 8:26:59 [Warning] option 'group_concat_max_len': unsigned value 0 adjusted to 4 [pyth...@db02 avail_mysql]$ grep concat /etc/my.cnf group_concat_max_len=1024 Please let me know if you need any additional information, or if there's an actual bug tracker that I've missed.... We've also seen this in: 5.0.67-d7-ourdelta-sail44-log and 5.0.67-percona-highperf-b10-log _______________________________________________ Mailing list: https://launchpad.net/~ourdelta-developers Post to : [email protected] Unsubscribe : https://launchpad.net/~ourdelta-developers More help : https://help.launchpad.net/ListHelp
