## Summary
This builds on top of the work in
https://github.com/astral-sh/ruff/pull/10597 to support `Ruff: Organize
imports` as an available source action.
To do this, we have to support `Clone`-ing for linter settings, since we
need to modify them in place to select import-related diagnostics
specifically (`I001` and `I002`).
## Test Plan
04282d01-dfda-4ac5-aa8f-6a92d5f85bfd
## Summary
This PR adds a new semantic model flag to indicate that the checker is
inside an f-string replacement field. This will be used to ignore
certain checks if the target version doesn't support a specific feature
like PEP 701.
fixes: #10761
## Test Plan
Add a test case from the raised issue.
Fixes#3259
## Summary
Renames `UnnecessaryComprehensionAnyAll` to
`UnnecessaryComprehensionInCall` and extends the check to `sum`, `min`,
and `max`, in addition to `any` and `all`.
## Test Plan
Updated snapshot test.
Built docs locally and verified the docs for this rule still render
correctly.
## Summary
We may not have had access to this in the past, but in short, if the
diagnostic is related to a specific section of a docstring, it seems
better to highlight the section (via the header) than the _entire_
docstring.
This should be completely compatible with existing `# noqa` since it's
always inside of a multi-line string anyway, and in such cases the `#
noqa` is always placed at the end of the multiline string.
Closes https://github.com/astral-sh/ruff/issues/10736.

## Summary
We lost the per-rule ignores when these were migrated to the AST, so if
_any_ `Q` rule is enabled, they're now all enabled.
Closes https://github.com/astral-sh/ruff/issues/10724.
## Test Plan
Ran:
```shell
ruff check . --isolated --select Q --ignore Q000
ruff check . --isolated --select Q --ignore Q001
ruff check . --isolated --select Q --ignore Q002
ruff check . --isolated --select Q --ignore Q000,Q001
ruff check . --isolated --select Q --ignore Q000,Q002
ruff check . --isolated --select Q --ignore Q001,Q002
```
...against:
```python
'''
bad docsting
'''
a = 'single'
b = '''
bad multi line
'''
```
## Summary
An annotated lambda assignment within a class scope is often
intentional. For example, within a dataclass or Pydantic model, these
are treated as fields rather than methods (and so can be passed values
in constructors).
I originally wrote this to special-case dataclasses and Pydantic
models... But was left feeling like we'd see more false positives here
for little gain (an annotated lambda within a `class` is likely
intentional?). Open to opinions, though.
Closes https://github.com/astral-sh/ruff/issues/10718.
## 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
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
<!-- 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.
## Summary
Closes#10228
The PR makes the blank lines rules keep track of the cell status when
running on a notebook, and makes the rules not trigger when the line is
the first of the cell.
## Test Plan
The example given in #10228 is added as a fixture, along with a few
tests from the main blank lines fixtures.
## Summary
Continuing with #7595, this PR moves the `Q004` rule to the AST checker.
## Test Plan
- [x] Existing test cases should pass
- [x] No ecosystem updates
## Summary
PEP 420 says [nested namespace
packages](https://peps.python.org/pep-0420/#nested-namespace-packages)
are allowed, i.e. marking a directory as a namespace package marks all
subdirectories in the subtree as namespace packages.
`is_package` is modified to use `Path::starts_with` and the order of
checks is reversed to do in-memory checks first before hitting the disk.
## Test Plan
Added unit tests. Previously all tests were run with `namespace_packages
== &[]`. Verified that one of the tests was failing before changing the
implementation.
## Future Improvements
The `is_package_with_cache` can probably be rewritten to avoid repeated
calls to `Path::starts_with`, by caching all directories up to the
`namespace_root`:
```ruff
let namespace_root = namespace_packages
.iter()
.filter(|namespace_package| path.starts_with(namespace_package))
.min();
```
## Summary
Closes#10337.
I've fixed the code to count usage of variable.
Usage count inside the block is reset when there is a following
statement.
- continue
- break
- return
## Test Plan
Add test case.
## Summary
The fix for PYI025 is currently marked as unsafe in non-global scopes
for both `.py` and `.pyi` files, on the grounds that all global-scope
symbols in Python are implicitly exported from the module, so changing
the name of something in the global scope could break other modules that
import the module we're fixing. Unlike in `.py` files, however, imported
symbols are never implicitly re-exported from stub files. Symbols are
only understood by static analysis tools as being re-exported from stubs
if they are marked as explicit re-exports, which take three forms:
```py
from foo import * # all symbols from foo are re-exported from the stub
# the "redundant" alias marks it as an explicit re-export
# (note that the alias needs to be identical to the symbol's "actual" name
# in order for it to be a re-export)
from bar import barrr as barrr
# inclusion in __all__ also marks it as an explicit re-export,
# just like in `.py` files
from baz import bazzz
__all__ = ["bazzz"]
```
This is [specc'd in PEP
484](https://peps.python.org/pep-0484/#stub-files), and means that we
can mark the fix for PYI025 as safe in more cases for `.pyi` files.
## Test Plan
`cargo test`. An existing test case goes from being an unsafe fix to a
safe fix in a `.pyi` fixture. I also added a new fixture so we have
coverage of global-scope imports that are marked as re-exports using
"redundant" `from collections.abc import Set as Set` aliases.
## Summary
Continuing with https://github.com/astral-sh/ruff/issues/7595, this PR
moves the `Q001`, `Q002`, `Q003` rules to the AST based checker.
## Test Plan
Make sure all of the existing test cases pass and verify there are no
ecosystem changes.
## Summary
This error was found browsing
8396966850.
Which failed when trying to autofix the PT014 violation in the following
code:
```python
@pytest.mark.parametrize('data, spec', [(1.0, 1.0), (1.0, 1.0)])
def test_numbers(data, spec):
...
```
Investigation revealed that the implementation was not properly tested,
when the duplicate value was also the last in the list. In particular
the following function, which is in charge of finding the comma
following an element to create the suggested fix,
0a99bd84ce/crates/ruff_linter/src/rules/flake8_pytest_style/rules/parametrize.rs (L647-L651)
would find the next comma even if it was outside the list itself leading
to a lot of code being deleted.
This PR fixes that.
## Test Plan
Added misbehaving code to the test fixture.
## Summary
Ensures that we use the raw identifier as provided in the source code,
rather than the normalized Unicode identifier.
This _does_ mean that we treat these as two separate identifiers, and
_don't_ merge them, even though Python will treat them as the same
symbol:
```python
import numpy as ℂℇℊℋℌℍℎℐℑℒℓℕℤΩℨKÅℬℭℯℰℱℹℴ
import numpy as CƐgHHHhIILlNZΩZKÅBCeEFio
```
I think that's fine, this is super rare anyway and would likely be
confusing for users.
Closes https://github.com/astral-sh/ruff/issues/10528.
## Test Plan
`cargo test`
## Summary
Adds commas as an accepted separator between copyright years by default,
which is actually documented in one spot, but not currently accurate.
Fixes#9477.
