New submission from Alexander Belopolsky: PyType_FromSpec() is a convenient function to create types dynamically in C extension modules, but its usefulness is limited by the fact that it creates new types using the default metaclass.
I suggest adding a new C API function PyObject *PyType_FromSpecEx(PyObject *meta, PyType_Spec *spec) and redefine PyType_FromSpec() as PyType_FromSpecEx((PyObject *)&PyType_Type, spec) This functionality cannot be implemented by user because PyType_FromSpec requires access to private slotoffsets table. A (trivial) patch attached. ---------- assignee: belopolsky components: Interpreter Core files: typeobject.diff keywords: needs review, patch messages: 169925 nosy: belopolsky, loewis priority: normal severity: normal stage: test needed status: open title: PyType_FromSpec should take metaclass as an argument type: enhancement versions: Python 3.4 Added file: http://bugs.python.org/file27137/typeobject.diff _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue15870> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
