## Summary
Update the name of `ASYNC109` to match
[upstream](https://flake8-async.readthedocs.io/en/latest/rules.html).
Also update to the functionality to match upstream by supporting
additional context managers from `asyncio` and `anyio`. This doesn't
change any of the detection functionality, but recommends additional
context managers from `asyncio` and `anyio` depending on context.
Part of https://github.com/astral-sh/ruff/issues/12039.
## Test Plan
Added fixture for asyncio recommendation
## Summary
S113 exists because `requests` doesn't have a default timeout, so
request without timeout may hang indefinitely
> B113: Test for missing requests timeout
This plugin test checks for requests or httpx calls without a timeout
specified.
>
> Nearly all production code should use this parameter in nearly all
requests, **Failure to do so can cause your program to hang
indefinitely.**
But httpx has default timeout 5s, so S113 for httpx request without
`timeout` argument is a false positive, only valid case would be
`timeout=None`.
https://www.python-httpx.org/advanced/timeouts/
> HTTPX is careful to enforce timeouts everywhere by default.
>
> The default behavior is to raise a TimeoutException after 5 seconds of
network inactivity.
## Test Plan
snap updated
Intern types using Salsa interning instead of in the `TypeInference`
result.
This eliminates the need for `TypingContext`, and also paves the way for
finer-grained type inference queries.
## Summary
This PR fixes the bug where the server was not considering the
`cells.structure.didOpen` field to sync up the new content of the newly
added cells.
The parameters corresponding to this request provides two fields to get
the newly added cells:
1. `cells.structure.array.cells`: This is a list of `NotebookCell` which
doesn't contain any cell content. The only useful information from this
array is the cell kind and the cell document URI which we use to
initialize the new cell in the index.
2. `cells.structure.didOpen`: This is a list of `TextDocumentItem` which
corresponds to the newly added cells. This actually contains the text
content and the version.
This wasn't a problem before because we initialize the cell with an
empty string and this isn't a problem when someone just creates an empty
cell. But, when someone copy-pastes a cell, the cell needs to be
initialized with the content.
fixes: #12201
## Test Plan
First, let's see the panic in action:
1. Press <kbd>Esc</kbd> to allow using the keyboard to perform cell
actions (move around, copy, paste, etc.)
2. Copy the second cell with <kbd>c</kbd> key
3. Delete the second cell with <kbd>dd</kbd> key
4. Paste the copied cell with <kbd>p</kbd> key
You can see that the content isn't synced up because the `unused-import`
for `sys` is still being highlighted but it's being used in the second
cell. And, the hover isn't working either. Then, as I start editing the
second cell, it panics.

Now, here's the preview of the fixed version:

This reverts commit b28dc9ac14.
We're not ready to stabilize the server yet. There's some pending work
for the VS Code extension and documentation improvements.
This change is to unblock Ruff release.
## Summary
<!-- What's the purpose of the change? What does it do, and why? -->
This is the implementation for the new rule of `pycodestyle (E204)`. It
follows the guidlines described in the contributing site, and as such it
has a new file named `whitespace_after_decorator.rs`, a new test file
called `E204.py`, and as such invokes the `function` in the `AST
statement checker` for functions and functions in classes. Linking #2402
because it has all the pycodestyle rules.
## Test Plan
<!-- How was it tested? -->
The file E204.py, has a `decorator` defined called wrapper, and this
decorator is used for 2 cases. The first one is when a `function` which
has a `decorator` is called in the file, and the second one is when
there is a `class` and 2 `methods` are defined for the `class` with a
`decorator` attached it.
Test file:
``` python
def foo(fun):
def wrapper():
print('before')
fun()
print('after')
return wrapper
# No error
@foo
def bar():
print('bar')
# E204
@ foo
def baz():
print('baz')
class Test:
# No error
@foo
def bar(self):
print('bar')
# E204
@ foo
def baz(self):
print('baz')
```
I am still new to rust and any suggestion is appreciated. Specially with
the way im using native ruff utilities.

## Summary
Fixes a few typos and consistency issues in the "Settings"
documentation:
- use "Ruff" consistently in the few places where "ruff" is used
- use double quotes in the few places where single quotes are used
- add backticks around rule codes where they are currently missing
- update a few example values where they are the same as the defaults,
for consistency
2nd commit might be controversial, as there are many options mentioned
where we don't currently link to the documentation sections, so maybe
it's done on purpose, as this will also appear in the JSON schema where
it's not desirable? If that's the case, I can easily drop it.
## Test Plan
Local testing.
## Summary
This PR fixes various bugs for computing the replacement range between
the original and modified source for the language server.
1. When finding the end offset of the source and modified range, we
should apply `zip` on the reversed iterator. The bug was that it was
reversing the already zipped iterator. The problem here is that the
length of both slices aren't going to be the same unless the source
wasn't modified at all. Refer to the [Rust
playground](https://play.rust-lang.org/?version=stable&mode=debug&edition=2021&gist=44f860d31bd26456f3586b6ab530c22f)
where you can see this in action.
2. Skip the first line when computing the start offset because the first
line start value will always be 0 and the default value of the source /
modified range start is also 0. So, comparing 0 and 0 is not useful
which means we can skip the first value.
3. While iterating in the reverse direction, we should only stop if the
line start is strictly less than the source start i.e., we should use
`<` instead of `<=`.
fixes: #12128
## Test Plan
Add test cases where the text is being inserted, deleted, and replaced
between the original and new source code, validate the replacement
ranges.
## Summary
Bandit now also reports `B113` on `httpx`
(https://github.com/PyCQA/bandit/pull/1060). This PR implements the same
logic, to detect missing or `None` timeouts for `httpx` alongside
`requests`.
## Test Plan
Snapshot tests.
Closes https://github.com/astral-sh/ruff/issues/12158
Hashing `Path` does not take into account path separators so `foo/bar`
is the same as `foobar` which is no good for our case. I'm guessing this
is an upstream bug, perhaps introduced by
45082b077b?
I'm investigating that further.
## Summary
This PR updates the linter, specifically the token-based rules, to work
on the tokens that come after a syntax error.
For context, the token-based rules only diagnose the tokens up to the
first lexical error. This PR builds up an error resilience by
introducing a `TokenIterWithContext` which updates the `nesting` level
and tries to reflect it with what the lexer is seeing. This isn't 100%
accurate because if the parser recovered from an unclosed parenthesis in
the middle of the line, the context won't reduce the nesting level until
it sees the newline token at the end of the line.
resolves: #11915
## Test Plan
* Add test cases for a bunch of rules that are affected by this change.
* Run the fuzzer for a long time, making sure to fix any other bugs.
## Summary
This PR updates Ruff to **not** generate auto-fixes if the source code
contains syntax errors as determined by the parser.
The main motivation behind this is to avoid infinite autofix loop when
the token-based rules are run over any source with syntax errors in
#11950.
Although even after this, it's not certain that there won't be an
infinite autofix loop because the logic might be incorrect. For example,
https://github.com/astral-sh/ruff/issues/12094 and
https://github.com/astral-sh/ruff/pull/12136.
This requires updating the test infrastructure to not validate for fix
availability status when the source contained syntax errors. This is
required because otherwise the fuzzer might fail as it uses the test
function to run the linter and validate the source code.
resolves: #11455
## Test Plan
`cargo insta test`
## Summary
This PR updates various references in the linter to compute the
line-width for summing the width of each `char` in a `str` instead of
computing the width of the `str` itself.
Refer to #12133 for more details.
fixes: #12130
## Test Plan
Add a file with null (`\0`) character which is zero-width. Run this test
case on `main` to make sure it panics and switch over to this branch to
make sure it doesn't panic now.
## Summary
Use the following to reproduce this:
```console
$ cargo run -- check --select=E275,E203 --preview --no-cache ~/playground/ruff/src/play.py --fix
debug error: Failed to converge after 100 iterations in `/Users/dhruv/playground/ruff/src/play.py` with rule codes E275:---

1 | yield,x
| ^^^^^ E275
|
= help: Added missing whitespace after keyword
Found 101 errors (100 fixed, 1 remaining).
[*] 1 fixable with the `--fix` option.
```
## Test Plan
Add a test case and run `cargo insta test`.
