Alex Waygood	89424cce5f	[ty] Do not emit errors if enums or NamedTuples constructed using functional syntax are used in type expressions (#17873) ... ## Summary This fixes some false positives that showed up in the primer diff for https://github.com/astral-sh/ruff/pull/17832 ## Test Plan new mdtests added that fail with false-positive diagnostics on `main`	2025-05-06 00:37:24 +01:00
Shunsuke Shibayama	fd76d70a31	[red-knot] fix narrowing in nested scopes (#17630) ... ## Summary This PR fixes #17595. ## Test Plan New test cases are added to `mdtest/narrow/conditionals/nested.md`. --------- Co-authored-by: Carl Meyer <carl@astral.sh>	2025-05-05 16:28:42 -07:00
Douglas Creager	ada4c4cb1f	[ty] Don't require default typevars when specializing (#17872) ... If a typevar is declared as having a default, we shouldn't require a type to be specified for that typevar when explicitly specializing a generic class: ```py class WithDefault[T, U = int]: ... reveal_type(WithDefault[str]()) # revealed: WithDefault[str, int] ``` --------- Co-authored-by: Alex Waygood <Alex.Waygood@Gmail.com>	2025-05-05 18:29:30 -04:00
Alex Waygood	bb6c7cad07	[ty] Fix false-positive [invalid-return-type] diagnostics on generator functions (#17871)	2025-05-05 21:44:59 +00:00
Douglas Creager	47e3aa40b3	[ty] Specialize bound methods and nominal instances (#17865) ... Fixes https://github.com/astral-sh/ruff/pull/17832#issuecomment-2851224968. We had a comment that we did not need to apply specializations to generic aliases, or to the bound `self` of a bound method, because they were already specialized. But they might be specialized with a type variable, which _does_ need to be specialized, in the case of a "multi-step" specialization, such as: ```py class LinkedList[T]: ... class C[U]: def method(self) -> LinkedList[U]: return LinkedList[U]() ``` --------- Co-authored-by: Alex Waygood <Alex.Waygood@Gmail.com>	2025-05-05 17:17:36 -04:00
Carl Meyer	4850c187ea	[ty] add cycle handling for FunctionType::signature query (#17833) ... This fixes cycle panics in several ecosystem projects (moved to `good.txt` in a following PR https://github.com/astral-sh/ruff/pull/17834 because our mypy-primer job doesn't handle it well if we move projects to `good.txt` in the same PR that fixes `ty` to handle them), as well as in the minimal case in the added mdtest. It also fixes a number of panicking fuzzer seeds. It doesn't appear to cause any regression in any ecosystem project or any fuzzer seed.	2025-05-05 12:12:38 -07:00
Max Mynter	101e1a5ddd	[semantic-syntax-tests] for for InvalidStarExpression, DuplicateMatchKey, and DuplicateMatchClassAttribute (#17754) ... Re: #17526 ## Summary Add integration tests for Python Semantic Syntax for `InvalidStarExpression`, `DuplicateMatchKey`, and `DuplicateMatchClassAttribute`. ## Note - Red knot integration tests for `DuplicateMatchKey` exist already in line 89-101. <!-- What's the purpose of the change? What does it do, and why? --> ## Test Plan This is a test. <!-- How was it tested? -->	2025-05-05 17:30:16 +00:00
