Test fixtures cause load_data to fail with Python 2.3

Database sync (sqlite) fails when trying to load initial data (in this case there is none). The error appears to stem from rsplit which is used in source:trunk/django/core/ and was introduced in [4659] with the test fixtures framework. I'm using the stock OS X Python (2.3.5) over here and I believe this function was introduced in 2.4.

Has patch: set

I added a patch for this problem. I tested it just with a syncdb on a fairly complex database on Python 2.5, and also verified that my rsplit replacement works correctly at least for cases like "a", "a.b", "a.b.c" etc.

Any update on when this patch might get committed -- we're unfortunately stuck on RHEL 4.x and RH won't honor support contracts if you install Python 2.4, even in a sandbox/separate path?

Hi Chris, you'd get a better response asking this question in the developer group.

The patch as written did not pass all the tests under python 2.4. So I'm checking in a modified version that seems to do the right thing. Can somebody with ready access to python2.3 please check that this fixes the problem (in particular, all the tests should still pass). If it passes under 2.3, we can mark this as fixed.

(In [4671]) Removed rsplit() usage for python2.3 compatibility. Refs #3625.

Resolution: fixed
Status: newclosed

Apparently if you want something tested you have to do it yourself, despite all the people who were apparently affected by this. :-(

I built Python 2.3 and database wrappers and it seems the rsplit() problem is gone. Some tests still fail under python2.3, but I don't believe it's related to this bug.
