## Summary
I noticed the example line in CONTRIBUTING.md:
```shell
cargo install nextest
```
Didn't appear to install the intended package cargo-nextest.
So I checked what it [should
be](https://nexte.st/book/installing-from-source.html) and replaced the
line:
```shell
cargo install cargo-nextest --locked
```
## Test Plan
Just checked the cargo install appeared to give sane looking results

## Summary
We've had success with `nextest` in other projects, so lets migrate
Ruff.
The Linux tests look a little bit faster (from 2m32s down to 2m8s), the
Windows tests look a little bit slower but not dramatically so.
Fixes#8368
Fixes https://github.com/astral-sh/ruff/issues/9186
## Summary
Arbitrary TOML strings can be provided via the command-line to override
configuration options in `pyproject.toml` or `ruff.toml`. As an example:
to run over typeshed and respect typeshed's `pyproject.toml`, but
override a specific isort setting and enable an additional pep8-naming
setting:
```
cargo run -- check ../typeshed --no-cache --config ../typeshed/pyproject.toml --config "lint.isort.combine-as-imports=false" --config "lint.extend-select=['N801']"
```

## Summary
Currently these rules apply the heuristic that if the original sequence
doesn't have a newline in between the final sequence item and the
closing parenthesis, the autofix won't add one for you. The feedback
from @ThiefMaster, however, was that this was producing slightly unusual
formatting -- things like this:
```py
__all__ = [
"b", "c",
"a", "d"]
```
were being autofixed to this:
```py
__all__ = [
"a",
"b",
"c",
"d"]
```
When, if it was _going_ to be exploded anyway, they'd prefer something
like this (with the closing parenthesis on its own line, and a trailing comma added):
```py
__all__ = [
"a",
"b",
"c",
"d",
]
```
I'm still pretty skeptical that we'll be able to please everybody here
with the formatting choices we make; _but_, on the other hand, this
_specific_ change is pretty easy to make.
## Test Plan
`cargo test`. I also ran the autofixes for RUF022 and RUF023 on CPython
to check how they looked; they looked fine to me.
## Summary
If a generic appears multiple times on the right-hand side, we should
only include it once on the left-hand side when rewriting.
Closes https://github.com/astral-sh/ruff/issues/9904.
## Summary
This review contains a fix for
[D405](https://docs.astral.sh/ruff/rules/capitalize-section-name/)
(capitalize-section-name)
The problem is that Ruff considers the sub-section header as a normal
section if it has the same name as some section name. For instance, a
function/method has an argument named "parameters". This only applies if
you use Numpy style docstring.
See: [ISSUE](https://github.com/astral-sh/ruff/issues/9806)
The following will not raise D405 after the fix:
```python
def some_function(parameters: list[str]):
"""A function with a parameters parameter
Parameters
----------
parameters:
A list of string parameters
"""
...
```
## Test Plan
```bash
cargo test
```

## Summary
This PR reduces the size of `Expr` from 80 to 64 bytes, by reducing the
sizes of...
- `ExprCall` from 72 to 56 bytes, by using boxed slices for `Arguments`.
- `ExprCompare` from 64 to 48 bytes, by using boxed slices for its
various vectors.
In testing, the parser gets a bit faster, and the linter benchmarks
improve quite a bit.
## Summary
Corrects mentions of `Path.is_link` to `Path.is_symlink` (the former
doesn't exist).
## Test Plan
```sh
python scripts/generate_mkdocs.py && mkdocs serve -f mkdocs.public.yml
```
Fixes#9857.
## Summary
Statements like `logging.info("Today it is: {day}")` will no longer be
ignored by RUF027. As before, statements like `"Today it is:
{day}".format(day="Tuesday")` will continue to be ignored.
## Test Plan
The snapshot tests were expanded to include new cases. Additionally, the
snapshot tests have been split in two to separate positive cases from
negative cases.
## Summary
Django's `mark_safe` can also be used as a decorator, so we should
detect usages of `@mark_safe` for the purpose of the relevant Bandit
rule.
Closes https://github.com/astral-sh/ruff/issues/9780.
## Summary
Given:
```python
"""Make a summary line.
Note:
----
Per the code comment the next two lines are blank. "// The first blank line is the line containing the closing
triple quotes, so we need at least two."
"""
```
It turns out we excluded the line ending in `"""`, because it's empty
(unlike for functions, where it consists of the indent). This PR changes
the `following_lines` iterator to always include the trailing newline,
which gives us correct and consistent handling between function and
module-level docstrings.
Closes https://github.com/astral-sh/ruff/issues/9877.
## Summary
The benchmarks show a pretty consistent 1% speedup here for all-rules,
though not enough to trigger our threshold of course:
It's a pretty big codebase using lots of different stuff, so a good
candidate for finding obscure problems.
I didn't look more closely which options are used (I have the feeling
`--select ALL` is not implied, since I see you adding it via
`check_options` for certain entries but not for others), the repo itself
has a pretty large ruff.toml - but assuming ecosystem just cares about
differences between base and head of a PR, `ALL` most likely makes
sense.
## Summary
This surprised me while working on adding a test. I thought about adding
an additional `note`, but how often is this incorrect? In general,
people reading the contributing guidelines probably want to enable this
flag and those who don't will know enough about the testing setup to
have their own commands/aliases.
## Test Plan
Ran CI on local fork and got an all green.
#2977 added the `allow-dict-calls-with-keyword-arguments` configuration
option for the `unnecessary-collection-call (C408)` rule, but it did not
update the rule description.
## Summary
This PR adds the `AnyNode` and `AnyNodeRef` implementation for
`FStringFormatSpec` node which will be required in the f-string
formatting.
The main usage for this is so that we can pass in the node directly to
`suppressed_node` in case debug expression is used to format is as
verbatim text.

## Summary
`max-positional-args` defaults to `max-args` if it's not specified and
the default to `max-args` is 5, so saying that the default is 3 is
definitely wrong. Ideally, we wouldn't specify a default at all for this
config option, but I don't think that's possible?

Not sure.
## Summary
Sadly, the Apple Silicon runners use macOS 14 and produce binaries that
segfault when run on macOS 11 (at least), and possibly on macOS 12
and/or macOS 13.
macOS 11 is EOL, but it doesn't seem like a good tradeoff to speed up
our release builds at the expense of user support and compatibility.
This reverts commit f0066e1b89.
Closes https://github.com/astral-sh/ruff/issues/9823.
## Summary
When we fall through to parsing, the comment-detection rule is a
significant portion of lint time. This PR adds an additional fast
heuristic whereby we abort if a comment contains two consecutive name
tokens (via the zero-allocation lexer). For the `ctypeslib.py`, which
has a few cases that are now caught by this, it's a 2.5x speedup for the
rule (and a 20% speedup for token-based rules).
