Working on the PEP 342/343 generator enhancements, I've got working send/throw/close() methods, but am not sure how to deal with getting __del__ to invoke close(). Naturally, I can add a "__del__" entry to its methods list easily enough, but the 'has_finalizer()' function in gcmodule.c only checks for a __del__ attribute on instance objects, and for tp_del on heap types.
It looks to me like the correct fix would be to check for tp_del always, not just on heap types. However, when I tried this, I started getting warnings from the tests, saying that 22 uncollectable objects were being created (all generators, in test_generators). It seems that the tests create cycles via globals(), since they define a bunch of generator functions and then call them, saving the generator iterators (or objects that reference them) in global variables after investigating this a bit, it seems to me that either has_finalizer() needs to _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
