Changeset [4724] MySQLdb versioncheck not working.

Reported by: derelm Assigned to: adrian
Milestone: Component: Database layer (models, ORM)
Version: SVN Keywords:

Description 

# django/db/backends/mysql/base.py
import MySQLdb as Database
#[...]
if Database.version_info < (1,2,1,'final',2):
	    raise ImportError, "MySQLdb-1.2.1p2 or newer is required; you have %s" % MySQLdb.__version__

Debian Sarge comes with MySQLdb 1.2.1.g2 but the check effectively doesn't kick in. 

>>> (1,2,1,'gamma',2) < (1,2,1,'final',2)
False

Also MySQLdb has been imported as Database so the Error raised needs to be 

raise ImportError, "MySQLdb-1.2.1p2 or newer is required; you have %s" % Database.__version__

Design Decision needed re: version support (we should prob. support a well-established os like sarge, but what are the differences between MySQLdb gamma and final)?

The import error is ready to be checked in.

I've looked around sourceforge for MySQLdb, but can't see any obvious way of finding the differences between 1.2.1 gamma and 1.2.1 final. I doubt, however, that there's any massive changes between a gamma release and a final release.

With gamma i could not specify DATABASE_OPTIONS = dict(charset="utf8") - that would raise an error. (suggested to fix my problems in #2635). So there seem to be enough differences to cause problems with Django.

The problem that original forced us to recommend the upgrade to 1.2.1p2 or later (#3279) was only fixed in that precise version. So no earlier versions are recommended for production (and hence any) use with Django. I'm about to check in a version check that knows the difference between "gamma" and "final, 1" and "final, 2".

  • status changed from new to closed.
  • resolution set to fixed.

(In [4751]) Fixed #3747 -- Added a stricter MySQLdb version check so that (1, 2, 1, 'final', 2) passes and (1, 2, 1, 'gamma') does not. Also fixed a problem in the error reporting when the check fails.

FWIW, this change broke my sites that are hosted on Dreamhost, as they have MySQL 1.2.1g3. Not suggesting it should be undone, just noting it, as I suspect there will be a lot of people wondering what happened.

Sorry, I didn't mean to post that as anonymous. That was from me, Jeff Croft.

Jeff: that's the problem (not Dreamhost in particular, but the breakage in general) and why we had a bit of a discussion about this on django-dev. We're going to somewhat damned whichever way we go, unfortunately. :-(

Fair enough. Sorry I missed the discussion on django-dev. No big problem for me, just had to rollback that one file on Dreamhost. :)
