[issue18181] super vs. someclass.__getattribute__

Ronald Oussoren added the comment: issue18181-locallookup-only-super.txt implements the current version of PEP 447, but only for the super object. In this version of the patch normal attribute lookup (object.__getattribute__ and PyObject_GenericGetAttr) are not yet affected. Another open iss

Ronald Oussoren added the comment: There now is a PEP for this issue: . The current version of the PEP describes a different API than documented by the attached proposal and the prove of concept code. I'm working on an updated implementation.

Ronald Oussoren added the comment: I don't think it is possible to avoid adding a new slot. The default implementation of tp_getattro (PyObject_GenericGetAttr) looks in the instance dict, while super does not (because it wants a less specific implementation). PyObject_GenericGetAttr will als

[issue18181] super vs. someclass.__getattribute__

New submission from Ronald Oussoren: Super() walks the MRO and looks for the looked-up attribute in the __dict__ of types on the MRO. This can cause problems when classes implement __getattribute__: a class on the MRO can implement a method that super() won't find because it isn't in the class
