## Summary
Currently, [this
line](716688d44e/crates/ruff_linter/src/fix/edits.rs (L101))
assumes that the `noqa` comment begins with an octothorpe followed by a
space. (`# `) With anyone's random code, this of course is not always
true.
When there's a multi-byte character after the leading octothorpe, such
as
[`\u0085`](https://www.fileformat.info/info/unicode/char/85/index.htm),
we try slicing from within the character, causing a panic.
To fix this, the logic has been changed to remove unused `noqa`
directives and keep any trailing comments, or removing the whole comment
if the comment is just the unused `noqa`
Fixes#10097.
## Test Plan
`cargo test`
## Summary
<!-- What's the purpose of the change? What does it do, and why? -->
Implement FURB164 in the issue #1348.
Relevant Refurb docs is here:
https://github.com/dosisod/refurb/blob/v2.0.0/docs/checks.md#furb164-no-from-float
I've changed the name from `no-from-float` to
`verbose-decimal-fraction-construction`.
## Test Plan
<!-- How was it tested? -->
I've written it in the `FURB164.py`.

## Summary
When `relative-imports-order = "closest-to-furthest"` is set, we should
_still_ put non-relative imports after relative imports. It's rare for
them to be in the same section, but _possible_ if you use
`known-local-folder`.
Closes https://github.com/astral-sh/ruff/issues/10655.
## Test Plan
New tests.
Also sorted this file:
```python
from ..models import ABC
from .models import Question
from .utils import create_question
from django_polls.apps.polls.models import Choice
```
With both:
- `isort view.py`
- `ruff check view.py --select I --fix`
And the following `pyproject.toml`:
```toml
[tool.ruff.lint.isort]
order-by-type = false
relative-imports-order = "closest-to-furthest"
known-local-folder = ["django_polls"]
[tool.isort]
profile = "black"
reverse_relative = true
known_local_folder = ["django_polls"]
```
I verified that Ruff and isort gave the same result, and that they
_still_ gave the same result when removing the relevant setting:
```toml
[tool.ruff.lint.isort]
order-by-type = false
known-local-folder = ["django_polls"]
[tool.isort]
profile = "black"
known_local_folder = ["django_polls"]
```
## Summary
Add a setting `extend-allowed-calls` to allow users to define their own
list of calls which allow boolean traps.
Resolves#10485.
Resolves#10356.
## Test Plan
Extended text fixture and added setting test.
## Summary
This PR fixes the bug for `DTZ007` rule where it didn't consider to
check for the presence of `%z` in f-strings. It also considers the
string parts of an implicitly concatenated f-strings for which I want to
find a better solution (#10308).
fixes: #10601
## Test Plan
Add test cases and update the snapshots.
## Summary
Fixes#10589.
Code that violates `F401` or `F841` (in other words, unused variables or
imports) should now appear greyed out or 'unused' in an editor.
## Test Plan
Put the following test code in a new file within the extension
development host window:
```python
import math
def func():
if False:
unused = "<- this should be greyed out"
```
The following test code should have greyed out/unused import and
variable names, like so:

src="e84a6e7a-49e2-4fed-9624-f8f9559e0837">
## Summary
Fixes#10588.
Most diagnostics from `ruff server` now appear as a much less alarming
warning instead of an error. Three diagnostics still appear as errors:
`F821` (`undefined name <name>`), `E902` (`IOError`) and `E999`
(`SyntaxError`).
## Test Plan
With an extension using the path to a locally-built executable, open a
file with multiple highlighted problems. Toggle the `Experimental
Server` setting on and off. The highlights should stay as warnings.
Then, modify the file to have a syntactically incorrect element. The
start of the invalid syntax should now have a red highlight.

## Summary
This PR updates the warning message for rule S305 to accurately reflect
the security concern over using ECB mode in block ciphers, which is
considered insecure compared to other modes like CBC or CTR. The
previous message incorrectly mentioned AES as a [block cipher
mode](https://en.wikipedia.org/wiki/Block_cipher_mode_of_operation),
which has been corrected to avoid confusion.

## Test Plan
No testing required as the change is limited to a minor change of
warning message update.
## Summary
The example for tab-after-comma (E242):
```python
a = 4,\t5
```
Use instead:
```python
a = 4, 3
```
is confusing since both the whitespace and the numbers are changed.
Change so the examples use the same numbers before/after.
## Test Plan
Untested.
- Clearly state in the documentation that passing `tz=None` is just as bad as not passing a `tz=` argument, from the perspective of these rules.
- Clearly state in the error messages exactly what the user is doing wrong, if the user is passing `tz=None` rather than failing to pass a `tz=` argument at all.
- Make error messages more concise, and separate out the suggested remedy from the thing that the user is identified as doing wrong.

## Summary
Fixes#10618.
This PR introduces a proper API for sending requests to the client and
handling any response sent back. Dynamic capability registration now
uses this new API, fixing an issue where a much more simplistic response
handler silently flushes a code action request that needed a response.
## Test Plan
#10618 can no longer be reproduced. No errors about unhandled responses
should appear in the extension output, and you should see this new log
when the server starts:
```
<DATE> <TIME> [info] <DURATION> INFO ruff_server::server Configuration file watcher successfully registered
```
## Summary
This PR adds an overview and roadmap to the `README.md` for the
`ruff_server` crate along with a rudimentary `CONTRIBUTING.md` that
explains some of the technical decisions behind the project and basic
information about local testing.
## Summary
<!-- What's the purpose of the change? What does it do, and why? -->
Similar to #10419, there was a case where there is a collision of C401
and C416 (as discussed in #10101).
Fixed this by implementing short-circuit for the comprehension of the
form `{x for x in foo}`.
## Test Plan
<!-- How was it tested? -->
Extended `C401.py` with the case where `set` is not builtin function,
and divided the case where the short-circuit should occur.
Removed the last testcase of `print(f"{ {set(a for a in 'abc')} }")`
test as this is invalid as a python code, but should I keep this?
## Summary
This is just a nitpicky improvement, but I thought it'd be a good
opportunity to look at the ruff source.

## Summary
This is not the holistic solution but just to fix that issue.
fixes: #10546
## Test Plan
Add a regression test for it and check the snapshots.
## Summary
Fixed false-positive on the rule `PLW1641`, where the explicit
assignment on the `__hash__` method is not counted as an definition of
`__hash__`. (Discussed in #10557).
Also, added one new testcase.
## Test Plan
Checked on `cargo test` in `eq_without_hash.py`.
Before the change, for the assignment into `__hash__`, only `__hash__ =
None` was counted as an explicit definition of `__hash__` method.
Probably any assignment into `__hash__` property could be counted as an
explicit definition of hash, so I removed `value.is_none_literal_expr()`
check.
