## Summary
If `RUF100` is ignored via `per-file-ignores`, we need to avoid raising
it. `RUF100` has special "self-ignore" logic, since the rule itself
deals with `# noqa` directives. This PR wires up `per-file-ignores` to
that "self-ignore" logic.
Closes https://github.com/astral-sh/ruff/issues/9297.
We should avoid adding `-> None` to stubs in `.pyi` files, along with a
few other cases. (We already ignore abstract methods.)
Closes https://github.com/astral-sh/ruff/issues/9270.
## Summary
This PR adds some helper structs to the linter paths to enable passing
in the pre-computed tokens and parsed source code during benchmarking,
to remove lexing and parsing from the overall linter benchmark
measurement. We already remove parsing for the formatter, and we have
separate benchmarks for the lexer and the parser, so this should make it
much easier to measure linter performance changes.
## Summary
Adds a rule to detect unions that include `typing.NoReturn` or
`typing.Never`. In such cases, the use of the bottom type is redundant.
Closes https://github.com/astral-sh/ruff/issues/9113.
## Test Plan
`cargo test`
## Summary
fixes#6956
details in issue
Following an advice in
https://github.com/astral-sh/ruff/issues/6956#issuecomment-1817672585,
this change separates expressions to 3 levels of "constant likelihood":
* literals, empty dict and tuples... (definitely constant, level 2)
* CONSTANT_CASE vars (probably constant, 1)
* all other expressions (0)
a comparison is marked yoda if the level is strictly higher on its left
hand side
following
https://github.com/astral-sh/ruff/issues/6956#issuecomment-1697107822
marking compound expressions of literals (e.g. `60 * 60` ) as constants
this change current behaviour on
`SomeClass().settings.SOME_CONSTANT_VALUE > (60 * 60)` in the fixture
from error to ok
## Summary
Given a function like:
```python
def func(x: int):
if not x:
raise ValueError
else:
raise TypeError
```
We now correctly use `NoReturn` as the return type, rather than `None`.
Closes https://github.com/astral-sh/ruff/issues/9201.
## Summary
Part of #8771. flake8-pyi will emit a Y018 error for unused TypeVars,
ParamSpecs or TypeVarTuples; Ruff currently only emits PYI018 for unused
TypeVars.
This is my first "proper" Ruff PR -- let me know if there's a better way
of doing this! Not sure if the repeated calls to `match_typing_expr()`
are ideal.
## Test Plan
I manually updated the fixtures to add some unused ParamSpecs and
TypeVarTuples, and then updated the snapshots using `cargo insta
review`. All tests then passed when run using `cargo test`.

## Summary
<!-- What's the purpose of the change? What does it do, and why? -->
New messages for "format" mode.
Fixes#9132
## Test Plan
<!-- How was it tested? -->
I ran the tests specified in `CONTRIBUTING.md`
```bash
cargo run -p ruff_cli -- check /path/to/some_files.py --no-cache
cargo run -p ruff_cli -- format --check /path/to/some_files.py --no-cache
cargo clippy --workspace --all-targets --all-features -- -D warnings
RUFF_UPDATE_SCHEMA=1 cargo test
pre-commit run --all-files --show-diff-on-failure
```
**Note:** In case no files are detected, either correctly formatted,
changed, or unchanged, it does not display a message. Wouldn't it be
better to show some message in this case?
## Summary
Given `Callable[[Callable[_P, _R]], Callable[_P, _R]]` from the
originating issue, when quoting `Callable`, we quoted the inner
`[Callable[_P, _R]]`, and then created a separate edit for the outer
`Callable`. Since there's an extra level of nesting in the subscript,
the edit for `[Callable[_P, _R]]` correctly did _not_ expand to the
entire expression. However, in this case, we should discard the inner
edit, since the expression is getting quoted by the outer edit anyway.
Closes https://github.com/astral-sh/ruff/issues/9162.
## Summary
A common mistake is to add quotes around one member in an `X | Y`-style
type union, as in:
```python
contract_versions_list: list[ContractVersion] | 'QuerySet[ContractVersion]' | None = None
```
However, doing so will lead to a runtime error if the annotation is
runtime-evaluated. This PR lints against such patterns.
Closes https://github.com/astral-sh/ruff/issues/9139.
## Summary
Fix dropped union expressions for piped non-types in `PYI055` autofix
If you had `type[int] | type[str] | str`, it would have dropped the
`str`, which breaks the type!
Closes#9156
