#27074: connection.is_usable() raises AttributeError after the connection is closed -------------------------------------+------------------------------------- Reporter: cjerdonek | Owner: nobody Type: | Status: new Cleanup/optimization | Component: Database layer | Version: 1.10 (models, ORM) | Severity: Normal | Resolution: Keywords: | Triage Stage: Accepted Has patch: 0 | Needs documentation: 0 Needs tests: 0 | Patch needs improvement: 0 Easy pickings: 0 | UI/UX: 0 -------------------------------------+-------------------------------------
Comment (by cjerdonek): I believe the trickiest part of the patch will be handling / dealing with the fact that there are multiple backend implementations of `is_usable()`. Ideally, I think one would want to put the logic in the base implementation and call `super()` as appropriate. Alternatively, it looks like it would be sufficient to include the logic in all three non-trivial implementations: mysql, oracle, and postgresql. Those each look like the following: {{{#!python def is_usable(self): try: self.connection.ping() except Database.Error: return False else: return True }}} -- Ticket URL: <https://code.djangoproject.com/ticket/27074#comment:5> Django <https://code.djangoproject.com/> The Web framework for perfectionists with deadlines. -- You received this message because you are subscribed to the Google Groups "Django updates" group.
