check_set_special_type_attr() is used to prevent setting the following attributes: * __name__ * __qualname__ * __module__ * __bases__ * __doc__ Right now, I cannot set the attribues on array.array type: $ ./python Python 3.10.0a7+ (heads/debug_doc2-dirty:0623fdb60d, Apr 29 2021, 12:06:18) >>> import array >>> array.array.__name__ = 'newname' TypeError: can't set attributes of built-in/extension type 'array.array' >>> array.array.__qualname__ = 'newname' TypeError: can't set attributes of built-in/extension type 'array.array' >>> array.array.__module__ = 'new module' TypeError: can't set attributes of built-in/extension type 'array.array' >>> array.array.__bases__ = (int,) TypeError: can't set attributes of built-in/extension type 'array.array' >>> array.array.__doc__ = 'doc' TypeError: can't set attributes of built-in/extension type 'array.array' I guess that type_setattro() is used and it checks for Py_TPFLAGS_IMMUTABLETYPE flag early. ---------- _______________________________________ 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
