#15144: Max age set in cache control no longer obeys timeout set with @cache_page decorator -----------------------------------+---------------------------------------- Reporter: jsdalton | Owner: nobody Status: new | Milestone: 1.3 Component: Cache system | Version: SVN Resolution: | Keywords: blocker, regression Stage: Unreviewed | Has_patch: 1 Needs_docs: 0 | Needs_tests: 0 Needs_better_patch: 0 | -----------------------------------+---------------------------------------- Comment (by jsdalton):
Okay, I'm uploading a new patch that: * Includes the regression tests I wrote under `test_view_decorator` that demonstrating the original issue * Fixes the issue originally raised in this ticket by incorporating Joshua's patch (15144.patch). * Includes a new test under `CacheMiddlewareTest`, `test_constructor`, which highlight a few bugs in the constructor that were discussed briefly here: http://groups.google.com/group/django- developers/browse_thread/thread/1a019e9d30de5c9d * Fixes the issues uncovered by the new test via a fairly minor rewrite of the `__init__` method of `CacheMiddleware` With regards to the first issue and fix, that's pretty much been discussed above so no need to say more about it. With regards to the second issue and fix, the main problem was that if the `CacheMiddleware` class was being used as middleware, the values for some of the instance attributes were not being set properly. (Basically, the `except KeyError` code path was never being executed.) The new test should be pretty self explanatory and should raise several failures when run against the original `CacheMiddleware.__init__` code currently in trunk The rewrite is also hopefully self explanatory as well. In addition to fixing the bugs I tried my best to simplify some of the code in an effort to make it more readable and easy to maintain going forward. A few notes of clarification: * I changed `cache_alias` to an instance attribute (i.e. `self.cache_alias`) in order to make it more testable (since it's not possible to determine which alias is being used from `self.cache` itself.) * I smoothed out a lot of places where variables were being explicitly compared against None etc. I think the new test adequately ensures that the appropriate initialization behavior is taking place, and some of those constructions were (IMO) making the code a bit unnecessarily verbose and hard to read. * I wish there was better testing to ensure the right values are being set in `cache_kwargs` and passed to `get_cache()` but I think the other upstream tests should fail if any of that were going wrong so it's probably okay. Anyhow, please let me know if there are any issues with the patch or anything else that needs to be addressed. (Apologies if I should have opened a new ticket to address those other bugs, I just figured it was easier to get it all taken care of here.) Cheers.
