[ty] Bind `typing.Self` in class attributes and assignment by charliermarsh · Pull Request #22487 · astral-sh/ruff

charliermarsh · 2026-01-09T23:24:18Z

Summary

We now bind typing.Self to its class context so class-body attribute annotations resolve correctly, including dataclass fields and regular instance assignments.

Closes astral-sh/ty#1124.

(A lot of conformance and ecosystem changes to review before this will be ready.)

charliermarsh · 2026-01-10T00:48:38Z

I believe the conformance changes are also improvements.

The removal of generics_self_attributes.py:29:5 is corrrect.

The removal of generics_self_usage.py:50:34 is correct.

charliermarsh · 2026-01-10T04:03:50Z

Current version looks better but needs more review of the ecosystem changes.

Need to review the ecosystem changes. Look likes all of the new diagnostics are in Zulip.
