## Summary
This PR normalizes line endings inside of strings to `\n` as required by the printer.
<!-- What's the purpose of the change? What does it do, and why? -->
## Test Plan
I added a new test using `\r\n` and ran the ecosystem check. There are no remaining end of line panics.

## Summary
This PR uses rayon to parallelize the stability check by scheduling each project as its own task.
<!-- What's the purpose of the change? What does it do, and why? -->
## Test Plan
I ran the ecosystem check. It now makes use of all cores (except at the end, there are some large projects).
## Performance
The check now completes in minutes where it took about 30 minutes before.

## Summary
This PR fixes an issue where the binary expression formatting removed parentheses around the left hand side of an expression.
<!-- What's the purpose of the change? What does it do, and why? -->
## Test Plan
I added a new regression test and re-ran the ecosystem check. It brings down the `check-formatter-stability` output from a 3.4MB file down to 900KB.

## Summary
This PR makes E731 a "manual" fix in one other context: when the lambda
is shadowing another variable in the scope. Function declarations (with
shadowing) cause issues for type checkers, and so rewriting an
annotation, e.g., in branches of an `if` statement can lead to failures.
Closes https://github.com/astral-sh/ruff/issues/5421.
## Summary
Completes the documentation for the `flake8-logging-format` rules.
Related to #2646.
I included both the `flake8-logging-format` recommendation to use the
`extra` keyword and the Pylint recommendation to pass format values as
parameters so that formatting is done lazily, as #970 suggests the
Pylint logging rules are covered by this ruleset. Using lazy formatting
via parameters is probably more common than avoiding formatting entirely
in favour of the `extra` argument, regardless.
## Test Plan
`python scripts/check_docs_formatted.py`
## Summary
This PR extracts a bunch of complex logic from `add_binding`, instead
running the the shadowing rules in the deferred handler, thereby
decoupling the binding phase (during which we build up the semantic
model) from the analysis phase, and generally making `add_binding` much
more focused.
This was made possible by improving the semantic model to better handle
deletions -- previously, we'd "lose track" of bindings if they were
deleted, which made this kind of refactor impossible.
## Test Plan
We have good automated coverage for this, but I want to benchmark it
separately.
## Summary
This PR fixes a silent failure that manifested itself in
https://github.com/astral-sh/ruff-vscode/issues/238. In short, if the
user provided invalid arguments to Ruff in the VS Code extension (like
`"ruff.args": ["a"]`), then we generated something like the following
command:
```console
/path/to/ruff --force-exclude --no-cache --no-fix --format json - --fix a --stdin-filename /path/to/file.py
```
Since this contains both `-` and `a` as the "input files", Ruff would
treat this as if we're linting the files names `-` and `a`, rather than
linting standard input.
This PR modifies out standard input detection to force standard input
when `--stdin-filename` is present, or at least one file is `-`. (We
then warn and ignore the others.)
## Summary
This was just an oversight -- the last remaining `todo!()` that I never
filled in. We clearly don't have any test coverage for it yet, but this
mimics the Pyright implementation.
## Summary
This PR adds some snapshot tests for the resolver based on executing
resolutions within a "mock" of the Airflow repo (that is: a folder that
contains a subset of the repo's files, but all empty, and with an
only-partially-complete virtual environment). It's intended to act as a
lightweight integration test, to enable us to test resolutions on a
"real" project without adding a dependency on Airflow itself.

## Summary
<!-- What's the purpose of the change? What does it do, and why? -->
Currently the URL at the bottom of the `ruff rule SLOT00x` output points
to Python 3.7 docs.
Given that Python 3.7 is now end-of-life (as of yesterday), let's
instead point users to the current Python docs.
## Test Plan
<!-- How was it tested? -->
## Summary
Consider Jupyter index for code frames (`--show-source`).
This solves two problems as mentioned in the linked issue:
> Omit any contents from adjoining cells
If the Jupyter index is present, we'll use that to check if the
surrounding
lines belong to the same cell as the content line. If not, we'll skip
that line
until we either reach the one which does or we reach the content line.
> code frame line number
If the Jupyter index is present, we'll use that to get the actual start
line in
corresponding to the computed start index.
## Test Plan
`cargo run --bin ruff -- check --no-cache --isolated --select=ALL --show-source /path/to/notebook.ipynb`
fixes: #5395
## Summary
Add Jupyter integration to the docs, specifically the Configuration and
FAQ sections.
## Test Plan
`mkdocs serve` and check that the new sections are visible and
functional.
fixes: #5396
## Summary
The `Y053` rule of `flake8-pyi` ignores docstrings, it only triggers on
other string literals.
The separate `Y021/PYI021` rule exists to disallow docstrings.
## Test Plan
Added some `# OK` test cases to `PYI053.py(i)` files.
## Summary
Implement Pylint rule `single-string-used-for-slots` (`C0205`) as
`single-string-slots` (`PLC0205`). This rule checks for single strings
being assigned to `__slots__`. For example
```python
class Foo:
__slots__: str = "bar"
def __init__(self, bar: str) -> None:
self.bar = bar
```
should be
```python
class Foo:
__slots__: tuple[str, ...] = ("bar",)
def __init__(self, bar: str) -> None:
self.bar = bar
```
Related to #970. Includes documentation.
## Test Plan
`cargo test`
## Summary
Replace same length equal line with dash line in D407
Do we want to update the message and autofix title to reflect this
change?
## Test Plan
Added test cases for:
- Equal line length == dash line length
- Equal line length != dash line length
fixes: #5378
## Summary
This PR contains the first step towards enabling robust first-party,
third-party, and standard library import resolution in Ruff (including
support for `typeshed`, stub files, native modules, etc.) by porting
Pyright's import resolver to Rust.
The strategy taken here was to start with a more-or-less direct port of
the Pyright's TypeScript resolver. The code is intentionally similar,
and the test suite is effectively a superset of Pyright's test suite for
its own resolver. Due to the nature of the port, the code is very, very
non-idiomatic for Rust. The code is also entirely unused outside of the
test suite, and no effort has been made to integrate it with the rest of
the codebase.
Future work will include:
- Refactoring the code (now that it works) to match Rust and Ruff
idioms.
- Further testing, in practice, to ensure that the resolver can resolve
imports in a complex project, when provided with a virtual environment
path.
- Caching, to minimize filesystem lookups and redundant resolutions.
- Integration into Ruff itself (use Ruff's existing settings, find rules
that can make use of robust resolution, etc.)
ruff_dev repeat recently broke (i think with the cargo update?):
> thread 'main' panicked at 'Command repeat: Short option names must be
unique for each argument, but '-n' is in use by both 'no_cache' and
'repeat''
This fixes this by removing the short argument.
## Summary
This formats call expressions with magic trailing comma and parentheses
behaviour but without call chaining
## Test Plan
Lots of new test fixtures, including some that don't work yet
## Summary
Implements PERF203 from #4789, which throws if a `try/except` block is
inside of a loop. Not sure if we want to extend the diagnostic to the
`except` as well, but I thought that that may get a little messy. We may
also want to just throw on the word `try` - open to suggestions though.
## Test Plan
`cargo test`
## Summary
Experimental release for Jupyter Notebook integration.
Currently, this requires a user to explicitly opt-in using the
[include](https://beta.ruff.rs/docs/settings/#include) configuration:
```toml
[tool.ruff]
include = ["*.py", "*.pyi", "**/pyproject.toml", "*.ipynb"]
```
Or, a user can pass in the file directly:
```sh
ruff check path/to/notebook.ipynb
```
For known limitations, please refer #5188
## Test Plan
Following command should work without the `--all-features` flag:
```sh
cargo dev round-trip /path/to/notebook.ipynb
```
Following command should work with the above config file along with
`select = ["ALL"]`:
```sh
cargo run --bin ruff -- check --no-cache --config=../test-repos/openai-cookbook/pyproject.toml --fix ../test-repos/openai-cookbook/
```
Passing the Jupyter notebook directly:
```sh
cargo run --bin ruff -- check --no-cache --isolated --select=ALL --fix ../test-repos/openai-cookbook/examples/Classification_using_embeddings.ipynb
```
