Martin v. Löwis <mar...@v.loewis.de> added the comment: The fast subtype checks cannot be supported in the limited API, as the layout of type objects is intentionally not exposed. It would be possible to expose a getter for the type flags; the individual flag values *are* part of the ABI.
I propose the attached patch, which replaces the fast subtype check with a slow one in the limited API. The patch would need to be extended to all subtype checks. It's not strictly necessary to include this patch into the 3.2 release; users could also explicitly call PyObject_IsSubclass as a work-around. The patch could then be added for 3.2.1. As another work-around, users can also use PyUnicode_CheckExact, which is even faster and might be correct in many cases as well. ---------- keywords: +patch Added file: http://bugs.python.org/file20644/unisub.diff _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue11067> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
