PyType_FromSpec() doesn't support 11 slots: * tp_dict * tp_mro * tp_cache * tp_subclasses * tp_weaklist * tp_vectorcall * tp_weaklistoffset (see PyMemberDef) * tp_dictoffset (see PyMemberDef) * tp_vectorcall_offset (see PyMemberDef) * bf_getbuffer * bf_releasebuffer https://docs.python.org/dev/c-api/type.html#c.PyType_Slot But it is possible to define tp_weaklistoffset, tp_dictoffset and tp_vectorcall_offset via Py_tp_members slot: https://docs.python.org/dev/c-api/structures.html#pymemberdef-offsets * "__dictoffset__" => tp_dictoffset * "__weaklistoffset__" => tp_weaklistoffset * "__vectorcalloffset__" => tp_vectorcall_offset Maybe we can do add new members for the 8 missing slots, especially bf_getbuffer and bf_releasebuffer? commit f7c4e236429606e1c982cacf24e10fc86ef4462f of bpo-40724 added Py_bf_getbuffer and Py_bf_releasebuffer slots to the C API, but these slots are still not available in the limited C API: see bpo-10181. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue41111> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
