Summary -- This PR aims to resolve (or help to resolve) #18442 and #19357 by encoding the CPython semantics around the `__class__` cell in our semantic model. Namely, > `__class__` is an implicit closure reference created by the compiler if any methods in a class body refer to either `__class__` or super. from the Python [docs](https://docs.python.org/3/reference/datamodel.html#creating-the-class-object). As noted in the variant docs by @AlexWaygood, we don't fully model this behavior, opting always to create the `__class__` cell binding in a new `ScopeKind::DunderClassCell` around each method definition, without checking if any method in the class body actually refers to `__class__` or `super`. As such, this PR fixes #18442 but not #19357. Test Plan -- Existing tests, plus the tests from #19783, which now pass without any rule-specific code. Note that we opted not to alter the behavior of F841 here because flagging `__class__` in these cases still seems helpful. See the discussion in https://github.com/astral-sh/ruff/pull/20048#discussion_r2296252395 and in the test comments for more information. --------- Co-authored-by: Alex Waygood <Alex.Waygood@Gmail.com> Co-authored-by: Mikko Leppänen <mleppan23@gmail.com> |
