[ty] Reject runtime generic aliases where class objects are required by charliermarsh · Pull Request #29398 · astral-sh/ruff

charliermarsh · 2026-10-14T21:20:59Z

Summary

We now reject runtime generic aliases where Python requires a class object:

def requires_class(cls: type) -> None: ...

requires_class(list)       # Accepted.
requires_class(list[int])  # Invalid argument.
isinstance([], list[int])  # Invalid argument.

We distinguish an alias such as list[int] from a class object that carries specialization information. This also corrects issubclass and singledispatch.register while preserving valid alias uses in annotations, constructors, and base classes. NumPy scalar names whose stubs describe them as aliases remain class objects and retain the type arguments that distinguish scalar widths. Specialized-class narrowing remains unchanged.

The conformance suite pin incorporates python/typing#2368, which removes a fixture that passed an alias where a class was expected.

Depends on #29403.

Closes astral-sh/ty#116.

Typing conformance results

The percentage of diagnostics emitted that were expected errors held steady at 98.24%. The percentage of expected errors that received a diagnostic held steady at 98.24%. The number of fully passing files held steady at 134/146.

Summary

How are test cases classified?

Each test case represents one expected error annotation or a group of annotations sharing a tag. Counts are per test case, not per diagnostic — multiple diagnostics on the same line count as one. Required annotations (E) are true positives when ty flags the expected location and false negatives when it does not. Optional annotations (E?) are true positives when flagged but true negatives (not false negatives) when not. Tagged annotations (E[tag]) require ty to flag exactly one of the tagged lines; tagged multi-annotations (E[tag+]) allow any number up to the tag count. Flagging unexpected locations counts as a false positive.
