## Summary
Give red-knot the ability to infer int literal types. This is quick and
easy, mostly because these types are a convenient way to observe
control-flow handling with simple assignments.
## Test Plan
Added test.
## Summary
In the [roadmap for `ruff
server`](https://github.com/astral-sh/ruff/discussions/10581) support
for vim and kate is listed. Therefore I added setup guides for them
based on the neovim guide. As I don't use pyright I wasn't able to
translate the corresponding part from the neovim guide.
## Test Plan
Doesn't apply.
* Potentially resolves#11619 (nondeterministic hashmap order across
different architectures) in F401 by replacing a hashmap with
nondeterministic traversal order with an ordered mapping.
I'm not sure how to test this with our CI/CD. I don't have an s390x
machine at home. Should I try it in Qemu?
## Summary
In an `__init__.py` file, it's not uncommon to lack a logical indent
(since it may just contain imports). In such cases, we were always
falling back to four-space indent. This PR adds detection for indents
within import groups.
Closes https://github.com/astral-sh/ruff/issues/11606.
## Summary
This PR aims to close#10095 by adding an option
`init-allow-undef-export` to the `pyflakes` settings. This option is
currently set to `true` such that behavior is kept identical.
But setting this option to `false` will lead to `F822` warnings to be
shown in all files, **including** `__init__.py` files.
As I've mentioned on #10095, I think `init-allow-undef-export=false`
would be the more user-friendly default option, as it creates fewer
surprises. @charliermarsh what do you think about making that the
default?
With this option in place, it's a single line fix for people that rely
on the old behavior.
And thinking longer term, for future major releases, one could probably
consider deprecating the option and eventually having people just `noqa`
these warnings if they are not wanted.
## Test Plan
I've added a `test_init_f822_enabled` test which repeats the test that
is done in the `init` test but this time with
`init-allow-undef-export=false` and the snap file correctly shows that
ruff will then trigger the otherwise suppressed F822 warning.
closes#10095
## Summary
Removed stray space in sample code snippet that is against ruff's own
default formatting rules.
This documentation appears on
https://docs.astral.sh/ruff/rules/unused-import/
## Test Plan
This is a trivially obvious change, verifiable with `ruff format
--check`
## Summary
Closes https://github.com/astral-sh/ruff/issues/11587.
## Test Plan
- Added a lint error to `test_server.py` in `vscode-ruff`.
- Validated that, prior to this change, diagnostics appeared in the
file.
- Validated that, with this change, no diagnostics were shown.
- Validated that, with this change, no diagnostics were fixed on-save.
## Summary
- Implements `Y066` from `flake8-pyi` as `PYI066`
- Fixes `PYI006` not being raised for `elif` clauses. This would have
conflicted with PYI006's implementation, so decided to do it in the same
PR.
## Test Plan
`cargo test` / `cargo insta review`
* Add a module type, `ModuleTypeId`
* Add an attribute lookup method `get_member` for `Type`
* Only implemented for `ModuleTypeId` and `ClassTypeId`
* [x] Should this be a trait?
*Answer: no*
* [x] Uses `unwrap`, but we should remove that. Maybe add a new variant
to `QueryError`?
*Answer: Return `Option<Type>` as is done elsewhere*
* Add `infer_definition_type` case for `Import`
* Add `infer_expr_type` case for `Attribute`
* Add a test to exercise these
* [x] remove all NOTE/FIXME/TODO after discussing with reviewers
## Summary
This PR ensures that if a variable is bound via `global`, and then the
`global` is read, the originating variable is also marked as read. It's
not perfect, in that it won't detect _rebindings_, like:
```python
from app import redis_connection
def func():
global redis_connection
redis_connection = 1
redis_connection()
```
So, above, `redis_connection` is still marked as unused.
But it does avoid flagging `redis_connection` as unused in:
```python
from app import redis_connection
def func():
global redis_connection
redis_connection()
```
Closes https://github.com/astral-sh/ruff/issues/11518.
## Summary
Follow up to https://github.com/astral-sh/ruff/pull/11521
Removes the extra added complexity for catch all match cases. This
matches the implementation of plain `else` statements.
## Test Plan
Added new test cases.

## Summary
Right now, we're discovering configuration files even within (e.g.)
virtual environments, because we're recursing without respecting the
`exclude` field on parent configuration.
Closes https://github.com/astral-sh/ruff-vscode/issues/478.
## Test Plan
Installed Pandas; verified that I saw no warnings:
## Summary
This PR fixes the bug to avoid flattening the global-only settings for
the new server.
This was added in https://github.com/astral-sh/ruff/pull/11497, possibly
to correctly de-serialize an empty value (`{}`). But, this lead to a bug
where the configuration under the `settings` key was not being read for
global-only variant.
By using #[serde(default)], we ensure that the settings field in the
`GlobalOnly` variant is optional and that an empty JSON object `{}` is
correctly deserialized into `GlobalOnly` with a default `ClientSettings`
instance.
fixes: #11507
## Test Plan
Update the snapshot and existing test case. Also, verify the following
settings in Neovim:
1. Nothing
```lua
ruff = {
cmd = {
'/Users/dhruv/work/astral/ruff/target/debug/ruff',
'server',
'--preview',
},
}
```
2. Empty dictionary
```lua
ruff = {
cmd = {
'/Users/dhruv/work/astral/ruff/target/debug/ruff',
'server',
'--preview',
},
init_options = vim.empty_dict(),
}
```
3. Empty `settings`
```lua
ruff = {
cmd = {
'/Users/dhruv/work/astral/ruff/target/debug/ruff',
'server',
'--preview',
},
init_options = {
settings = vim.empty_dict(),
},
}
```
4. With some configuration:
```lua
ruff = {
cmd = {
'/Users/dhruv/work/astral/ruff/target/debug/ruff',
'server',
'--preview',
},
init_options = {
settings = {
configuration = '/tmp/ruff-repro/pyproject.toml',
},
},
}
```
## Summary
This PR brings back the functionality to remove empty strings when
converting to an f-string in `UP032`.
For context, https://github.com/astral-sh/ruff/pull/8712 added this
functionality to remove _trailing_ empty strings but it got removed in
https://github.com/astral-sh/ruff/pull/8697 possibly unexpectedly so.
There's one difference which is that this PR will remove _any_ empty
strings and not just trailing ones. For example,
```diff

(

- ""

```
## Test Plan
Run `cargo insta test` and update the snapshots.
## Summary
This PR updates the sequence sorting (`RUF022` and `RUF023`) to avoid
using the owned data from the string token. Instead, we will directly
use the reference to the data on the AST. This does introduce a lot of
lifetimes but that's required.
The main motivation for this is to allow removing the `lex_starts_at`
usage easily.
### Alternatives
1. Extract the raw string content (stripping the prefix and quotes)
using the `Locator` and use that for comparison
2. Build up an
[`IndexVec`](3e30962077/crates/ruff_index/src/vec.rs)
and use the newtype index in place of the string value itself. This also
does require lifetimes so we might as well just use the method in this
PR.
## Test Plan
`cargo insta test` and no ecosystem changes
## Summary
Fixes#11506.
`RuffSettingsIndex::new` now searches for configuration files in parent
directories.
## Test Plan
I confirmed that the original test case described in the issue worked as
expected.
## Summary
Concurrent GitLab runners clone projects into separate directories, e.g.
`{builds_dir}/$RUNNER_TOKEN_KEY/$CONCURRENT_ID/$NAMESPACE/$PROJECT_NAME`.
Since the fingerprint uses the full path to the file, the fingerprints
calculated by Ruff are different depending on which concurrent runner it
executes on, so often an MR will appear to remove all existing issues
and add them with new fingerprints.
I've adjusted the fingerprint function to use the project relative path,
which fixes this. Unfortunately this will have a breaking change for any
current users of this output - the fingerprints will change and appear
in GitLab as all linting messages having been fixed and then created.
## Test Plan
`cargo nextest run`
Running `ruff check --output-format gitlab` in a git repo, moving the
repo and running again, verifying no diffs between the outputs
## Summary
Fixes#11534.
`DocumentQuery::source_type` now returns `PySourceType::Stub` when the
document is a `.pyi` file.
## Test Plan
I confirmed that stub-specific rule violations appeared with a build
from this PR (they were not visible from a `main` build).

Hi!
I left out some of the functions in the migration rule which became
removed in NumPy 2.0:
- `np.alltrue`
- `np.anytrue`
- `np.cumproduct`
- `np.product`
Addressing: https://github.com/numpy/numpy/issues/26493
## Summary
<!-- What's the purpose of the change? What does it do, and why? -->
Current doc says `sys.version[0]` will select the first digit of a major
version number (correct) then as an example says
> e.g., `"3.10"` would evaluate to `"1"`
(would actually evaluate to `"3"`). Changed the example version to a
two-digit number to make the problem more clear.
## Test Plan
<!-- How was it tested? -->
ran the following:
- `cargo run -p ruff -- check
crates/ruff_linter/resources/test/fixtures/flake8_2020/YTT301.py
--no-cache`
- `cargo insta review`
- `cargo test`
which all passed.
## Summary
Rule `logging-warn` (`G010`) prescribes a change from `warn` to
`warning` and has a corresponding autofix, but the autofix is mistakenly
titled ```"Convert to `warn`"``` instead of ```"Convert to `warning`"```
(the latter is what the autofix actually does). Seems to be a plain
typo.
## Summary
Fixes#11516
`ruff server` was sending both regular source actions and notebook
source actions back when passed an empty action filter. This PR makes a
few small changes so that notebook source actions are not sent when
regular source actions are sent, which means that an empty filter will
only return regular source actions.
## Test Plan
I confirmed that duplicate code actions no longer appeared in Neovim,
using a configuration similar to the one from the original issue.

## Summary
It turns out that `singledispatch` does end up evaluating all arguments,
even though only the first is used to dispatch.
Closes https://github.com/astral-sh/ruff/issues/11520.
## Summary
Addresses #8451 by implementing rule 116 to add an unsafe fix when sleep
is used with a >24 hour interval to instead consider sleeping forever.
This rule is added as async instead as I my understanding was that these
trio rules would be moved to async anyway.
There are a couple of TODOs, which address further extending the rule by
adding support for lookups and evaluations, and also supporting `anyio`.
## Summary
This PR updates the `FA102` rule logic to use the `Importer` which is
available on the `Checker`.
The main motivation is that this would make updating the `Importer` to
use the `Tokens` struct which will be required to remove the
`lex_starts_at` usage in `Insertion::start_of_block` method.
## Test Plan
`cargo insta test`
