STINNER Victor <vstin...@python.org> added the comment:
https://docs.python.org/dev/c-api/typeobj.html#Py_TPFLAGS_IMMUTABLETYPE says: "This bit is set for type objects that are immutable: type attributes cannot be set nor deleted." Is it possible that a metatype (type subtype) overrides tp_setattro and ignores the Py_TPFLAGS_IMMUTABLETYPE flag? Should we suggest that metatypes implemented in C and overridding tp_setattro should take the Py_TPFLAGS_IMMUTABLETYPE flag in account? When a type overrides tp_setattro, I understand that it's fine since it's only used to set attributes of its instances, not on the type itself. -- See also bpo-43770 "Rework C types initialization": some types explicitly sets explicitly tp_setattro to PyObject_GenericSetAttr. But it's unrelated since it's used to set attributes of type instances. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue43908> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
