## Summary
This refactors the `ruff_cli` integration tests to create a new
`RuffCheck` struct -- this holds options to configure the "common case"
flags that we want to pass to Ruff (e.g. `--no-cache`, `--isolated`,
etc). This helps reduce the boilerplate and (IMO) makes it more obvious
what the core logic of each test is by keeping only the "interesting"
parameters.
## Test Plan
`cargo test`
closes#8732
I noticed that the reference to the setting in the rule docs doesn't
work, but there seem to be something wrong with pylint settings in
general in the docs - the "For related settings, see ...." is also
missing there.
# Summary
This setting behaves similarly to the ``from_first`` setting in isort
upstream, and sorts "from X import Y" type imports before straight
imports.
Like the other PR I added, happy to refactor if this is better in
another form.
Fixes#8662
# Test plan
I've added a unit test, and ran this on a large codebase that relies on
this setting in isort to verify it doesn't have unexpected side effects.
Closes https://github.com/astral-sh/ruff/issues/7347Closes#3970 via use of `include`
We could update examples in our documentation, but I worry since we do
not have versioned documentation users on older versions would be
confused. Instead, I'll open an issue to track updating use of `ruff
check .` in the documentation sometime in the future.
Semantically it makes sense to put certain contextmanagers into separate
with statements. Currently asyncio.timeout and its relatives in anyio
and trio are exempt from SIM117.
Closes https://github.com/astral-sh/ruff/issues/8606
## Summary
Exempt asyncio.timeout and related functions from SIM117 (Collapse with
statements where possible).
See https://github.com/astral-sh/ruff/issues/8606 for more.
## Test Plan
Extended the insta tests.
## Summary
Fixes#8750. `import __main__` is now considered a first-party import,
and is grouped accordingly by the linter and formatter.
## Test Plan
Added a test based off code supplied in the linked issue.
## Summary
In 2.0, Pydantic has moved the `BaseSettings` class to a separate
package called `pydantic-settings`
(https://docs.pydantic.dev/2.4/migration/#basesettings-has-moved-to-pydantic-settings),
which results in a false positive on `RUF012` (`mutable-class-default`).
A simple fix for that would be adding `pydantic_settings.BaseSettings`
base to the `has_default_copy_semantics` helper, which I've done in this
PR.

## Summary
It turns out that some type checkers rely on the presence of ellipses in
`Protocol` interfaces and abstract methods, in order to differentiate
between default implementations and stubs. This PR modifies the preview
behavior of `PIE790` to avoid flagging "unnecessary" ellipses in such
cases.
Closes https://github.com/astral-sh/ruff/issues/8756.
## Test Plan
`cargo test`
If you define a subclass of `pydantic.BaseModel`, and then a subclass of
_that_ class in the same file, we'll now correctly treat it as
runtime-evaluated.
Closes https://github.com/astral-sh/ruff/issues/7893.

## Summary
Adds the Pylint rule E1132 to check for repeated keyword arguments in a
function call.
## Test Plan
Tested via the included unit tests and manual spot checking.
## Summary
Ensures that we can catch cases like:
```python
ages = {"Tom": 23, "Maria": 23, "Dog": 11}
age = ages.get("Cat", None)
```
Previously, the rule was somewhat useless, as it only checked for
literal accesses.
Closes https://github.com/astral-sh/ruff/issues/8760.
Fix an instability where await was followed by a breaking fluent style
expression:
```python
test_data = await (
Stream.from_async(async_data)
.flat_map_async()
.map()
.filter_async(is_valid_data)
.to_list()
)
```
Note that this technically a minor style change (see ecosystem check)
Closes https://github.com/astral-sh/ruff/issues/8695
We track the smallest offset seen for overindented lines then only
reduce the indentation of the lines that far to preserve indentation in
other lines. This rule's behavior now matches our formatter, which is
nice.
We may want to gate this with preview.
## Summary
When running ruff in verbose mode with `-v`, the first debug logs show
where the config settings are taken from. For example:
```
❯ ruff check ./some_file.py -v
[2023-11-17][00:16:25][ruff_cli::resolve][DEBUG] Using pyproject.toml (parent) at /Users/vince/demo/ruff.toml
```
This threw me off for a second because I knew I had no python project
there, and therefore no `pyproject.toml` file. Then I realised it was
actually reading a `ruff.toml` file (obvious when you read the whole
print I suppose) and that the pyproject.toml is a hardcoded string in
the debug log.
I think it would be nice to tweak the wording slightly so it is clear
that the settings don't neccessarily have to come from a
`pyproject.toml` file.
We ended up with a syntax error here via `from trio import
lowlevel.checkpoint`. The new solution avoids that error, but does miss
cases like:
```py
from trio.lowlevel import Timer
```
Where it could insert `from trio.lowlevel import Timer, checkpoint`.
Instead, it'll add `from trio import lowlevel`.

Update to [Rust
1.74](https://blog.rust-lang.org/2023/11/16/Rust-1.74.0.html) and use
the new clippy lints table.
The update itself introduced a new clippy lint about superfluous hashes
in raw strings, which got removed.
I moved our lint config from `rustflags` to the newly stabilized
[workspace.lints](https://doc.rust-lang.org/stable/cargo/reference/workspaces.html#the-lints-table).
One consequence is that we have to `unsafe_code = "warn"` instead of
"forbid" because the latter now actually bans unsafe code:
```
error[E0453]: allow(unsafe_code) incompatible with previous forbid
--> crates/ruff_source_file/src/newlines.rs:62:17
|
62 | #[allow(unsafe_code)]
| ^^^^^^^^^^^ overruled by previous forbid
|
= note: `forbid` lint level was set on command line
```

## Summary
I think it's reasonable to avoid raising `INP001` for scripts, and
shebangs are one sufficient way to detect scripts.
Closes https://github.com/astral-sh/ruff/issues/8690.
I checked for ipython-specific builtins on python 3.11 using
```python
import json
from subprocess import check_output
builtins_python = json.loads(check_output(["python3", "-c" "import json; print(json.dumps(dir(__builtins__)))"]))
builtins_ipython = json.loads(check_output(["ipython3", "-c" "import json; print(json.dumps(dir(__builtins__)))"]))
print(sorted(set(builtins_ipython) - set(builtins_python)))
```
and updated the relevant constant and match. The list changes from
`display`
to
`__IPYTHON__`, `display`, `get_ipython`.
Followup to #8707
## Summary
This exists to power a test, but it ends up affecting the behavior of
all files in the directory. Namely, it means that these files _aren't_
excluded when you format or lint them directly, since in that case, Ruff
will fall back to looking at the `pyproject.toml` in
`crates/ruff_linter/resources/test/fixtures`, which _doesn't_ exclude
these files, unlike our top-level `pyproject.toml`.
## Summary
We already support inserting imports for `I002` -- this PR just adds the
same fix for `FA102`, which is explicitly about `from __future__ import
annotations`.
Closes https://github.com/astral-sh/ruff/issues/8682.
## Summary
It seems like the range of an `ExprStringLiteral` can be somewhat
unreliable when the string is part of an implicit concatenation with an
f-string. Using the tokens themselves is more reliable.
Closes#8680.
Closes https://github.com/astral-sh/ruff/issues/7784.
## Summary
`display` is a special-cased builtin in IPython. This PR adds it to the
builtin namespace when analyzing IPython notebooks.
Closes https://github.com/astral-sh/ruff/issues/8702.
## Summary
This adds an autofix for PIE800 (unnecessary spread) -- whenever we see
a `**{...}` inside another dictionary literal, just delete the `**{` and
`}` to inline the key-value pairs. So `{"a": "b", **{"c": "d"}}` becomes
just `{"a": "b", "c": "d"}`.
I have enabled this just for preview mode.
## Test Plan
Updated the preview snapshot test.
## Summary
Implements
[FURB136](https://github.com/dosisod/refurb/blob/master/docs/checks.md#furb136-use-min-max)
that checks for `if` expressions that can be replaced with `min()` or
`max()` calls. See issue #1348 for more information.
This implementation diverges from Refurb's original implementation by
retaining the order of equal values. For example, Refurb suggest that
the following expressions:
```python
highest_score1 = score1 if score1 > score2 else score2
highest_score2 = score1 if score1 >= score2 else score2
```
should be to rewritten as:
```python
highest_score1 = max(score1, score2)
highest_score2 = max(score1, score2)
```
whereas this implementation provides more correct alternatives:
```python
highest_score1 = max(score2, score1)
highest_score2 = max(score1, score2)
```
## Test Plan
Unit test checks all eight possibilities.
Testing the compatibility with the future stable black style, i realized
the `ruff_python_formatter` dev main was lacking the
`--skip-magic-trailing-comma` option. This does not affect `ruff
format`.
Usage:
```shell
cargo run --bin ruff_python_formatter -p ruff_python_formatter -- --skip-magic-trailing-comma --emit stdout scratch.py
```
## Summary
This adds a ``no-sections`` option for isort in the linter, similar to
the ``no_sections`` option that exists in upstream isort
(https://pycqa.github.io/isort/docs/configuration/options.html#no-sections)
This option puts all imports except for ``__future__`` into the same
section, and is mostly used by monorepos.
I've taken a bit of a leap in assuming that ruff wants to support the
exact same option; more than happy to refactor if you'd prefer a
different way of setting this up.
Fixes#8653
## Test Plan
I've added a test and have run it on a large Python codebase that uses
isort with --no-sections. The option is disabled by default.
While fixing #8661 I noticed that the code structure for sorting imports
could be simplified.
## Summary
- Move the logic for `force_sort_within_sections` from `isort/mod.rs` to
`isort/ordering.rs` => now there is just one line in `isort/mod.rs`:
`let imports = order_imports(import_block, settings);` which yields the
sorted imports
- Change the function signature of `order_imports` to directly return a
`Vec<EitherImport<'a>>` => no need for `OrderedImportBlock`
I think this is a bit of an improvement because the code is simpler and
there should be a bit of a speedup when setting
`force-sort-within-sections` to true. Indeed, when it's set to true
we're now directly ordering all the imports, whereas before we would
first order the straight imports, then the from imports, combine them
and finally sort the combination a second time (this is probably not
noticeable in practice though).
## Test Plan
No tests added, this is a simple refactor.
For the `PLW0129` rule, the f-string case shouldn't match against bytes
literal as f-strings cannot contain them. F-strings are made up of
either string literals or formatted expressions.
## Summary
This PR adds (unsafe) fixes to the flake8-annotations rules that enforce
missing return types, offering to automatically insert type annotations
for functions with literal return values. The logic is smart enough to
generate simplified unions (e.g., `float` instead of `int | float`) and
deal with implicit returns (`return` without a value).
Closes https://github.com/astral-sh/ruff/issues/1640 (though we could
open a separate issue for referring parameter types).
Closes https://github.com/astral-sh/ruff/issues/8213.
## Test Plan
`cargo test`
Fixes#8661
## Summary
Imports like `from x import y` don't have an "asname" for the module, so
they were placed before imports like `import x as w` since `None` <
`Some(s)` for any string s.
The fix is to first sort by `first_alias`, since it's `None` for `import
x as w`, and then by `asname`.
## Test Plan
I included the example from the issue to avoid future regressions.
When using the autofixer for `Q000` it does not remove the backslashes
from quotes that no longer need escaping.
This new rule checks for such backslashes (regardless whether they come
from the autofixer or not) and can remove them.
fixes#8617
## Summary
This PR extends `unnecessary-pass` (`PIE790`) to flag unnecessary
ellipsis expressions in addition to `pass` statements. A `pass` is
equivalent to a standalone `...`, so it feels correct to me that a
single rule should cover both cases.
When we look to v0.2.0, we should also consider deprecating `PYI013`,
which flags ellipses only for classes.
Closes https://github.com/astral-sh/ruff/issues/8602.
