This issue was fixed differently in bpo-44263, by adding a test in PyType_Ready(): // bpo-44263: tp_traverse is required if Py_TPFLAGS_HAVE_GC is set. // Note: tp_clear is optional. if (type->tp_flags & Py_TPFLAGS_HAVE_GC && type->tp_traverse == NULL) { PyErr_Format(PyExc_SystemError, "type %s has the Py_TPFLAGS_HAVE_GC flag " "but has no traverse function", type->tp_name); return -1; } commit ee7637596d8de25f54261bbeabc602d31e74f482 Author: Victor Stinner <vstin...@python.org> Date: Tue Jun 1 23:37:12 2021 +0200 bpo-44263: Py_TPFLAGS_HAVE_GC requires tp_traverse (GH-26463) The PyType_Ready() function now raises an error if a type is defined with the Py_TPFLAGS_HAVE_GC flag set but has no traverse function (PyTypeObject.tp_traverse). ---------- nosy: +vstinner resolution: rejected -> fixed _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue1662> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
