Changes our warning for combined use of `--preview` and `--select
NURSERY` to a hard error.
This should go out _before_ #9680 where we will ban use of `NURSERY`
outside of preview as well (see #9683).

## Summary
Per https://github.com/astral-sh/ruff/issues/9570:
> `dtype` are a bit of a strange beast, but definitely best thought of
as instances, not classes, and they are meant to be comparable not just
to their own class, but also to the corresponding scalar types (e.g.,
`x.dtype == np.float32`) and strings (e.g., `x.dtype == ['i1,i4']`;
basically, `__eq__` always tries to do `dtype(other)`.
This PR thus allows comparisons to `dtype` in preview.
Closes https://github.com/astral-sh/ruff/issues/9570.
## Test Plan
`cargo test`
## Summary
This review contains a fix for
[RET504](https://docs.astral.sh/ruff/rules/unnecessary-assign/)
(unnecessary-assign)
The problem is that Ruff suggests combining a return statement inside
contextlib.suppress. Even though it is an unsafe fix it might lead to an
invalid code that is not equivalent to the original one.
See: https://github.com/astral-sh/ruff/issues/5909
## Test Plan
```bash
cargo test
```
## Summary
Given a statement like `colors = 6`, we currently treat the cell as an
automagic (since `colors` is an automagic) -- i.e., we assume it's
equivalent to `%colors = 6`. This PR adds some additional detection
whereby if the statement is an _assignment_, we avoid treating it as
such. I audited the list of automagics, and I believe this is safe for
all of them.
Closes https://github.com/astral-sh/ruff/issues/8526.
Closes https://github.com/astral-sh/ruff/issues/9648.
## Test Plan
`cargo test`
## Summary
This review contains a fix for
[PIE810](https://docs.astral.sh/ruff/rules/multiple-starts-ends-with/)
(multiple-starts-ends-with)
The problem is that ruff suggests combining multiple startswith/endswith
calls into a single call even though there might be a call with tuple of
strs. This leads to calling startswith/endswith with tuple of tuple of
strs which is incorrect and violates startswith/endswith conctract and
results in runtime failure.
However the following will be valid and fixed correctly =>
```python
x = ("hello", "world")
y = "h"
z = "w"
msg = "hello world"
if msg.startswith(x) or msg.startswith(y) or msg.startswith(z) :
sys.exit(1)
```
```
ruff --fix --select PIE810 --unsafe-fixes
```
=>
```python
if msg.startswith(x) or msg.startswith((y,z)):
sys.exit(1)
```
See: https://github.com/astral-sh/ruff/issues/8906
## Test Plan
```bash
cargo test
```
## Summary
This rule was just incorrect, it didn't match the examples in the docs.
(It's a very rarely-used rule since it's not included in any of the
conventions.)
Closes https://github.com/astral-sh/ruff/issues/9452.
## Summary
Add a rule for defaultdict(default_factory=callable). Instead suggest
using defaultdict(callable).
See: https://github.com/astral-sh/ruff/issues/9509
If a user tries to bind a "non-callable" to default_factory, the rule
ignores it. Another option would be to warn that it's probably not what
you want. Because Python allows the following:
```python
from collections import defaultdict
defaultdict(default_factory=1)
```
this raises after you actually try to use it:
```python
dd = defaultdict(default_factory=1)
dd[1]
```
=>
```bash
KeyError: 1
```
Instead using callable directly in the constructor it will raise (not
being a callable):
```python
from collections import defaultdict
defaultdict(1)
```
=>
```bash
TypeError: first argument must be callable or None
```
## Test Plan
```bash
cargo test
```
## Summary
When we are analyzing the implicit return rule this change add an
additional check to verify if the call expression has been annotated
with NoReturn type from typing module.
See: https://github.com/astral-sh/ruff/issues/5474
## Test Plan
```bash
cargo test
```
Previously, without the 'wrap_help' feature enabled, Clap would not do
any auto-wrapping of help text. For help text with long lines, this
tends to lead to non-ideal formatting. It can be especially difficult to
read when the width of the terminal is smaller.
This commit enables 'wrap_help', which will automatically cause Clap to
query the terminal size and wrap according to that. Or, if the terminal
size cannot be determined, it will default to a maximum line width of
100.
Ref https://github.com/astral-sh/ruff/pull/9599#discussion_r1464992692
## Summary
If you paste in the TOML for our default configuration (from the docs),
it's rejected by our JSON Schema:
It seems like the issue is with:
```toml
# Set the line length limit used when formatting code snippets in
# docstrings.
#
# This only has an effect when the `docstring-code-format` setting is
# enabled.
docstring-code-line-length = "dynamic"
```
Specifically, since that value uses a custom Serde implementation, I
guess Schemars bails out? This PR adds a custom representation to allow
`"dynamic"` (but no other strings):
This seems like it should work but I don't have a great way to test it.
Closes https://github.com/astral-sh/ruff/issues/9630.
## Summary
Checks for unnecessary `dict` comprehension when creating a new
dictionary from iterable. Suggest to replace with
`dict.fromkeys(iterable)`
See: https://github.com/astral-sh/ruff/issues/9592
## Test Plan
```bash
cargo test
```
## Summary
This PR introduces a new rule to sort `__slots__` and `__match_args__`
according to a [natural sort](https://en.wikipedia.org/wiki/Natural_sort_order), as was
requested in https://github.com/astral-sh/ruff/issues/1198#issuecomment-1881418365.
The implementation here generalises some of the machinery introduced in
3aae16f1bd
so that different kinds of sorts can be applied to lists of string
literals. (We use an "isort-style" sort for `__all__`, but that isn't
really appropriate for `__slots__` and `__match_args__`, where nearly
all items will be snake_case.) Several sections of code have been moved
from `sort_dunder_all.rs` to a new module, `sorting_helpers.rs`, which
`sort_dunder_all.rs` and `sort_dunder_slots.rs` both make use of.
`__match_args__` is very similar to `__all__`, in that it can only be a
tuple or a list. `__slots__` differs from the other two, however, in
that it can be any iterable of strings. If slots is a dictionary, the
values are used by the builtin `help()` function as per-attribute
docstrings that show up in the output of `help()`. (There's no
particular use-case for making `__slots__` a set, but it's perfectly
legal at runtime, so there's no reason for us not to handle it in this
rule.)
Note that we don't do an autofix for multiline `__slots__` if `__slots__` is a dictionary: that's out of scope. Everything else, we can nearly always fix, however.
## Test Plan
`cargo test` / `cargo insta review`.
I also ran this rule on CPython, and the diff looked pretty good

## Summary
Implement rule `mutable-fromkeys-value` (`RUF023`).
Autofixes
```python
dict.fromkeys(foo, [])
```
to
```python
{key: [] for key in foo}
```
The fix is marked as unsafe as it changes runtime behaviour. It also
uses `key` as the comprehension variable, which may not always be
desired.
Closes#4613.
## Test Plan
`cargo test`
## Summary
When determining whether _any_ settings have namespace packages, we need
to consider the global settings (as would be provided via `--config`).
This was a subtle fallout of a refactor.
Closes https://github.com/astral-sh/ruff/issues/9579.
## Test Plan
Tested locally by compiling Ruff and running against this
[namespace-test](https://github.com/gokay05/namespace-test) repo.
## Summary
This PR detects whether PLR0917 is being applied to a method or class
method, and if so, it ignores the first argument for the purposes of
counting the number of positional arguments.
## Test Plan
New tests have been added to the corresponding fixture.
Closes#9552.
## Summary
Long ago, we had a single `ruff` crate. We started to break that up, and
at some point, we wanted to separate the CLI from the core library. So
we created `ruff_cli`, which created a `ruff` binary. Later, the `ruff`
crate was renamed to `ruff_linter` and further broken up into additional
crates.
(This is all from memory -- I didn't bother to look through the history
to ensure that this is 100% correct :))
Now that `ruff` no longer exists, this PR renames `ruff_cli` to `ruff`.
The primary benefit is that the binary target and the crate name are now
the same, which helps with downstream tooling like `cargo-dist`, and
also removes some complexity from the crate and `Cargo.toml` itself.
## Test Plan
- Ran `rm -rf target/release`.
- Ran `cargo build --release`.
- Verified that `./target/release/ruff` was created.
## Summary
#5920 with a fix for the erroneous slice in `module_name`. Fixes#9547.
## Test Plan
Added `import bbb.ccc._ddd as eee` to the test fixture to ensure it no
longer panics.
`cargo test`
## Summary
This implements the rule proposed in #1198 (though it doesn't close the
issue, as there are some open questions about configuration that might
merit some further discussion).
## Test Plan
`cargo test` / `cargo insta review`. I also ran this PR branch on the CPython
codebase with `--fix --select=RUF022 --preview `, and the results looked
pretty good to me.

## Summary
Right now, if you run with `explicit-preview-rules`, and use something
like `select = ["RUF017"]`, we won't actually enable fixing for that
rule, because `fixable = ["ALL"]` (the default) won't include `RUF017`
due to the `explicit-preview-rules`.
The framing in this PR is that `explicit-preview-rules` should only
affect the enablement selectors, whereas the fixable selectors should
just include all possible matching rules. I think this will lead to the
most intuitive behavior.
Closes https://github.com/astral-sh/ruff/issues/9282. (An alternative to
https://github.com/astral-sh/ruff/pull/9284.)
## Summary
This PR is a more holistic fix for
https://github.com/astral-sh/ruff/issues/9534 and
https://github.com/astral-sh/ruff/issues/9159.
When we visit the AST, we track nodes that we need to visit _later_
(deferred nodes). For example, when visiting a function, we defer the
function body, since we don't want to visit the body until we've visited
the rest of the statements in the containing scope.
However, deferred nodes can themselves contain deferred nodes... For
example, a function body can contain a lambda (which contains a deferred
body). And then there are rarer cases, like a lambda inside of a type
annotation.
The aforementioned issues were fixed by reordering the deferral visits
to catch common cases. But even with those fixes, we still fail on cases
like:
```python
from __future__ import annotations
import re
from typing import cast
cast(lambda: re.match, 1)
```
Since we don't expect lambdas to appear inside of type definitions.
This PR modifies the `Checker` to keep visiting until all the deferred
stacks are empty. We _already_ do this for any one kind of deferred
node; now, we do it for _all_ of them at a level above.
## Summary
This is effectively the same problem as
https://github.com/astral-sh/ruff/pull/9175. And this just papers over
it again, though I'm gonna try a more holistic fix in a follow-up PR.
The _real_ fix here is that we need to continue to visit deferred items
until they're exhausted since, e.g., we still get this case wrong
(flagging `re` as unused):
```python
import re
cast(lambda: re.match, 1)
```
Closes https://github.com/astral-sh/ruff/issues/9534.
## Summary
I found that `cargo benchmark lexer` didn't work as expected:
```shell
❯ cargo benchmark lexer

Running benches/linter.rs (target/release/deps/linter-e449086ddfd8ad8c)
```
Turns out that `cargo bench -p ruff_benchmark` is now recommended over
`cargo benchmark`, so updating the docs to reflect that.
## Summary
Closes#9508 .
Add `__prepare__` method to dunder method list in
`is_known_dunder_method`.
## Test Plan

## Summary
Fixes#8334.
`Display` has been implemented for `ruff_workspace::Settings`, which
gives a much nicer and more readable output to `--show-settings`.
Internally, a `display_settings` utility macro has been implemented to
reduce the boilerplate of the display code.
### Work to be done
- [x] A lot of formatting for `Vec<_>` and `HashSet<_>` types have been
stubbed out, using `Debug` as a fallback. There should be a way to add
generic formatting support for these types as a modifier in
`display_settings`.
- [x] Several complex types were also stubbed out and need proper
`Display` implementations rather than falling back on `Debug`.
- [x] An open question needs to be answered: how important is it that
the output be valid TOML? Some types in settings, such as a hash-map
from a glob pattern to a multi-variant enum, will be hard to rework into
valid _and_ readable TOML.
- [x] Tests need to be implemented.
## Test Plan
Tests consist of a snapshot test for the default `--show-settings`
output and a doctest for `display_settings!`.

## Summary
Fix the message for `__aenter__ ` in PLC2801 (introduced in
https://github.com/astral-sh/ruff/pull/9166)
There is no `aenter` builtin in Python, so the current message is
misleading.
I take the message from original lint
https://github.com/pylint-dev/pylint/blob/main/pylint/constants.py#L211
P.S. I think here should be more accurate synchronization with original
lint (e.g. the current implementation will not lint `__enter__` on my
first sight), but it is out-of-scope of this change.

## Summary
<!-- What's the purpose of the change? What does it do, and why? -->
I noticed that there should be a missing period added to some of the new
error messages for Unnecessary dunder call:
```
sandpit\test.py:6:16: PLC2801 Unnecessary dunder call to `__getattribute__`. Access attribute directly or use getattr built-in function..
```
## Test Plan
Static analysis of the implementation, as this has no existing test
cases.
## Summary
We haven't found time to flip this on, so feels like it's best to remove
it for now -- can always restore from source when we get back to it.
## Summary
Closes#9319, implements the [`SIM911` rule from
`flake8-simplify`](https://github.com/MartinThoma/flake8-simplify/pull/183).
#### Note
I wasn't sure whether or not to include
```rs
if checker.settings.preview.is_disabled() {
return;
}
```
at the beginning of the function with violation logic if the rule's
already declared as part of `RuleGroup::Preview`.
I've seen both variants, so I'd appreciate some feedback on that :)
## Summary
This PR attempts to improve `builtin-attribute-shadowing` (`A003`), a
rule which has been repeatedly criticized, but _does_ have value (just
not in the current form).
Historically, this rule would flag cases like:
```python
class Class:
id: int
```
This led to an increasing number of exceptions and special-cases to the
rule over time to try and improve it's specificity (e.g., ignore
`TypedDict`, ignore `@override`).
The crux of the issue is that given the above, referencing `id` will
never resolve to `Class.id`, so the shadowing is actually fine. There's
one exception, however:
```python
class Class:
id: int
def do_thing() -> id:
pass
```
Here, `id` actually resolves to the `id` attribute on the class, not the
`id` builtin.
So this PR completely reworks the rule around this _much_ more targeted
case, which will almost always be a mistake: when you reference a class
member from within the class, and that member shadows a builtin.
Closes https://github.com/astral-sh/ruff/issues/6524.
Closes https://github.com/astral-sh/ruff/issues/7806.
## Summary
Sort of a random PR to make the coupling between `pyproject_config` and
`resolver` more explicit by passing it to the `Resolver`, rather than
threading it through to each individual method.
Saves 2% on Airflow:

Fixes#8721
## Summary
This implements the rule proposed in #8721, as RUF021. `and` always
binds more tightly than `or` when chaining the two together.
(This should definitely be autofixable, but I'm leaving that to a
followup PR for now.)
## Test Plan
`cargo test` / `cargo insta review`
## Summary
This PR enables Ruff to remove redefined imports, as in:
```python
import os
import os
print(os)
```
Previously, Ruff would flag `F811` on the second `import os`, but
couldn't fix it.
For now, this fix is marked as safe, but only available in preview.
Closes https://github.com/astral-sh/ruff/issues/3477.
## Summary
On `main`, we flag redefinitions in cases like:
```python
import os
x = 1
if x > 0:
import os
```
That is, we consider these to be in the "same branch", since they're not
in disjoint branches. This matches Flake8's behavior, but it seems to
lead to false positives.
## Summary
Given a docstring like:
```python
def func(x: int, args: tuple[int]):
"""Toggle the gizmo.
Args:
x: Some argument.
args: Some other arguments.
"""
```
We were considering the `args:` descriptor to be an indented docstring
section header (since `Args:`) is a valid header name. This led to very
confusing diagnostics.
This PR makes the parsing a bit more lax in this case, such that if we
see a nested header that's more deeply indented than the preceding
header, and the preceding section allows sub-items (like `Args:`), we
avoid treating the nested item as a section header.
Closes https://github.com/astral-sh/ruff/issues/9426.
## Summary
After we apply fixes, the source code might be transformed. And yet,
we're using the _unmodified_ source code to compute locations in some
cases (e.g., for displaying parse errors, or Jupyter Notebook cells).
This can lead to subtle errors in reporting, or even panics. This PR
modifies the linter to use the _transformed_ source code for such
computations.
Closes https://github.com/astral-sh/ruff/issues/9407.
I just fixed this false negative in flake8-pyi
(https://github.com/PyCQA/flake8-pyi/pull/460), and then realised ruff
has the exact same bug! Luckily it's a very easy fix.
(The bug is that unused protocols go undetected if they're generic.)
## Summary
This is similar to https://github.com/astral-sh/ruff/pull/8876, but more
limited in scope:
1. It only applies to `# fmt: skip` (like Black). Like `# isort: on`, `#
fmt: on` needs to be on its own line (still).
2. It only delimits on `#`, so you can do `# fmt: skip # noqa`, but not
`# fmt: skip - some other content` or `# fmt: skip; noqa`.
If we want to support the `;`-delimited version, we should revisit
later, since we don't support that in the linter (so `# fmt: skip; noqa`
wouldn't register a `noqa`).
Closes https://github.com/astral-sh/ruff/issues/8892.
When formatting notebooks, we populate the `id` field for cells that do
not have one. Previously, we generated a UUID v4 which resulted in
non-deterministic formatting. Here, we generate the UUID from a seeded
random number generator instead of using true randomness. For example,
here are the first five ids it would generate:
```
7fb27b94-1602-401d-9154-2211134fc71a
acae54e3-7e7d-407b-bb7b-55eff062a284
9a63283c-baf0-4dbc-ab1f-6479b197f3a8
8dd0d809-2fe7-4a7c-9628-1538738b07e2
72eea511-9410-473a-a328-ad9291626812
```
We also add a check that an id is not present in another cell to prevent
accidental introduction of duplicate ids.
The specification is lax, and we could just use incrementing integers
e.g. `0`, `1`, ... but I have a minor preference for retaining the UUID
format. Some discussion
[here](https://github.com/astral-sh/ruff/pull/9359#discussion_r1439607121)
— I'm happy to go either way though.
Discovered via #9293
## Summary
Ensures that any lint rules that include line locations render them as
relative to the cell (and include the cell number) when inside a Jupyter
notebook.
Closes https://github.com/astral-sh/ruff/issues/6672.
## Test Plan
`cargo test`
## Summary
Given:
```python
F"{"ڤ
```
We try to locate the "unclosed left brace" error by subtracting the
quote size from the lexer offset -- so we subtract 1 from the end of the
source, which puts us in the middle of a Unicode character. I don't
think we should try to adjust the offset in this way, since there can be
content _after_ the quote. For example, with the advent of PEP 701, this
string could reasonably be fixed as:
```python
F"{"ڤ"}"
````
Closes https://github.com/astral-sh/ruff/issues/9379.
## Summary
This PR adds an autofix for the newly added PYI058 rule (added in
#9313). ~~The PR's current implementation is that the fix is only
available if the fully qualified name of `Generator` or `AsyncGenerator`
is being used:~~
- ~~`-> typing.Generator` is converted to `-> typing.Iterator`;~~
- ~~`-> collections.abc.AsyncGenerator[str, Any]` is converted to `->
collections.abc.AsyncIterator[str]`;~~
- ~~but `-> Generator` is _not_ converted to `-> Iterator`. (It would
require more work to figure out if `Iterator` was already imported or
not. And if it wasn't, where should we import it from? `typing`,
`typing_extensions`, or `collections.abc`? It seems much more
complicated.)~~
The fix is marked as always safe for `__iter__` or `__aiter__` methods
in `.pyi` files, but unsafe for all such methods in `.py` files that
have more than one statement in the method body.
This felt slightly fiddly to accomplish, but I couldn't _see_ any
utilities in
https://github.com/astral-sh/ruff/tree/main/crates/ruff_linter/src/fix
that would have made it simpler to implement. Lmk if I'm missing
something, though -- my first time implementing an autofix! :)

## Test Plan
`cargo test`
## Summary
This PR modifies our `Cargo.toml` files to use workspace dependencies
for _all_ dependencies, rather than the status quo of sporadically
trying to use workspace dependencies for those dependencies that are
used across multiple crates. I find the current situation more confusing
and harder to manage, since we have a mix of workspace and crate-local
dependencies, whereas this setup consistently uses the same approach for
all dependencies.
## Summary
The `ureq` dev-dependency in the ruff_cli workspace member is unused.
There are no code references to `ureq` in that crate.
## Test Plan
ruff and its tests continues to compile with the dependency removed. :)
The "wsl" crate was last touched in 2019, whereas the "is-wsl" crate was
last updated in 2023. Additionally, it is unclear whether the "wsl"
crate supports both WSL1 and WSL2 (which was announced in 2019), whereas
the "is-wsl" crate explicitly supports both WSL1 and WSL2.
The required code changes are minimal, since both crates provide only a
`is_wsl() -> bool` function.
paramiko `set_missing_host_key_policy` has mandatory positional arg.

## Summary
Remove the period from a couple short messages, for consistency with all
other short messages.
All other short rule messages lack such a period, except for long
messages made of multiple sentences.
## Test Plan
Tests modified accordingly.
Not sure if this would qualify as a breaking change because user-visible
messages are modified.
## Summary
This PR implements Y058 from flake8-pyi -- this is a new flake8-pyi rule
that was released as part of `flake8-pyi 23.11.0`. I've followed the
Python implementation as closely as possible (see
858c0918a8),
except that for the Ruff version, the rule also applies to `.py` files
as well as for `.pyi` files. (For `.py` files, we only emit the
diagnostic in very specific situations, however, as there's a much
higher likelihood of emitting false positives when applying this rule to
a `.py` file.)
## Test Plan
`cargo test`/`cargo insta review`
## Summary
Historically, we encoded this list by extracting the `__all__`. I went
to update it, but... is there really any value in it? Seems easier to
just treat `typing_extensions` as an alias for `typing`.
Closes https://github.com/astral-sh/ruff/issues/9334.
## Summary
We stopped releasing this a while ago and no longer advertise it
anywhere. IMO, we should remove it so that we stop paying the cost of
maintaining it. If we want to revive it, we can always do so from Git.
## Summary
This is a non-behavior-changing refactor to follow-up
https://github.com/astral-sh/ruff/pull/9321 by modifying
`DisplayParseError` to use owned data and make it useable as a
standalone error type (rather than using references and implementing
`Display`). I don't feel very strongly either way. I thought it was
awkward that the `FormatCommandError` had two branches in the display
path, and wanted to represent the `Parse` vs. other cases as a separate
enum, so here we are.
## Summary
The logic that detects continuations assumed that tokens themselves
cannot span multiple lines. However, strings _can_ -- even single-quoted
strings.
Closes https://github.com/astral-sh/ruff/issues/9323.
## Summary
I always found it odd that we had to pass this in, since it's really
higher-level context for the error. The awkwardness is further evidenced
by the fact that we pass in fake values everywhere (even outside of
tests). The source path isn't actually used to display the error; it's
only accessed elsewhere to _re-display_ the error in certain cases. This
PR modifies to instead pass the path directly in those cases.
## Summary
This PR modifies the semantics of `runtime-evaluated-decorators` to
respect decorators on both classes _and_ functions. Historically, this
only respected classes, since the common use-case is (e.g.)
`pydantic.BaseModel` -- but functions are equally valid.
Closes https://github.com/astral-sh/ruff/issues/9312.
## Test Plan
`cargo test`
## Summary
This helps a bit with (but does not close) the issues described in
https://github.com/astral-sh/ruff/issues/9311. E.g., now, we at least
see: `error: Failed to format main.py: source contains syntax errors:
invalid syntax. Got unexpected token '=' at byte offset 20`.
## Summary
Given:
```python
from somewhere import get_cfg
def lookup_cfg(cfg_description):
cfg = get_cfg(cfg_description)
if cfg is not None:
return cfg
raise AttributeError(f"No cfg found matching {cfg_description}")
```
We were analyzing the method from last-to-first statement. So we saw the
`raise`, then assumed the method _always_ raised. In reality, though, it
_might_ return. This PR improves the branch analysis to respect these
mixed cases.
Closes https://github.com/astral-sh/ruff/issues/9269.
Closes https://github.com/astral-sh/ruff/issues/9304.
