Armin Rigo added the comment: I don't see in general how the patch can be kept compatible with extension modules that change the tp_dict of arbitrary types. All I can think of is a way to be safe against extension modules that only change the tp_dict of their own non-heap types (i.e. types defined in C). The method cache is disabled for types that don't have the Py_TPFLAGS_HAVE_VERSION_TAG flag; so if we would leave this flag out of Py_TPFLAGS_DEFAULT, non-heap types from extension modules would by default not use the cache.
I'm not sure about the API for this. Would we then need to put Py_TPFLAGS_HAVE_VERSION_TAG explicitly on all core types? And about how to change tp_dict in a way that makes the cache happy - do we need to turn type_modified() into a public API? All in all, the lack of abstraction of the C API might kill the idea of this patch for CPython. __________________________________ Tracker <[EMAIL PROTECTED]> <http://bugs.python.org/issue1878> __________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
