Description (last modified by )
Some of the related manager methods do multiple data-modifying operations but do not use any transaction management at all. This is clearly broken. This isn't a regression, so isn't a release blocker for that reason. However, this is a potential data corruption issue, so might be nice to fix for 1.6, too.
I am not sure how to test this. Maybe post_delete/save signals could be used to force exceptions and thus rollback.
EDIT: Forgot to add that a patch for some problematic methods available in https://github.com/django/django/pull/1684.
