## Summary
This is a cleanup PR. I am fixing various English language spelling
errors. This is mostly in docs and docstrings.
## Test Plan
The usual CI tests were run. I tried to build the docs (though I had
some troubles there). The testing needs here are, I trust, very low
impact. (Though I would happily test more.)
## Summary
Stop flagging each invocation of `django.utils.safestring.mark_safe`
(also available at, `django.utils.html.mark_safe`) as an error.
Instead, allow string literals as valid uses for `mark_safe`.
Also, update the documentation, pointing at
`django.utils.html.format_html` for dynamic content generation use
cases.
Closes#16702
## Test Plan
I verified several possible uses, but string literals, are still
flagged.

## Summary
This PR stabilizes the preview behavior introduced in
https://github.com/astral-sh/ruff/pull/15719 to recognize all symbols
named `TYPE_CHECKING` as type-checking
checks in `if TYPE_CHECKING` conditions. This ensures compatibility with
mypy and pyright.
This PR also stabilizes the new behavior that removes `if 0:` and `if
False` to be no longer considered type checking blocks.
Since then, this syntax has been removed from the typing spec and was
only used for Python modules that don't have a `typing` module
([comment](https://github.com/astral-sh/ruff/pull/15719#issuecomment-2612787793)).
The preview behavior was first released with Ruff 0.9.5 (6th of
February), which was about a month ago. There are no open issues or PRs
for the changed behavior
## Test Plan
The snapshots for `SIM108` change because `SIM108` ignored type checking
blocks but it can no
simplify `if 0` or `if False` blocks again because they're no longer
considered type checking blocks.
The changes in the `TC005` snapshot or only due to that `if 0` and `if
False` are no longer recognized as type checking blocks

# Summary
The goal of this PR is to address various issues around parsing
suppression comments by
1. Unifying the logic used to parse in-line (`# noqa`) and file-level
(`# ruff: noqa`) noqa comments
2. Recovering from certain errors and surfacing warnings in these cases

## Summary
`RUF035` has been backported into bandit as `S704` in this
[PR](https://github.com/PyCQA/bandit/pull/1225)
This moves the rule and its corresponding setting to the `flake8-bandit`
category
## Test Plan
`cargo nextest run`

Co-authored-by: Micha Reiser <micha@reiser.io>
## Summary
Resolves#16445.
`UP028` is now no longer always fixable: it will not offer a fix when at
least one `ExprName` target is bound to either a `global` or a
`nonlocal` declaration.
## Test Plan
`cargo nextest run` and `cargo insta test`.
The PR addresses issue #16396 .
Specifically:
- If the exit statement contains a code keyword argument, it is
converted into a positional argument.
- If retrieving the code from the exit statement is not possible, a
violation is raised without suggesting a fix.

## Summary
Resolves#16374.
`PLW0177` now also reports the pattern of a case branch if it is an
attribute access whose qualified name is that of either `np.nan` or
`math.nan`.
As the rule is in preview, the changes are not preview-gated.
## Test Plan
`cargo nextest run` and `cargo insta test`.
## Summary
Resolves 3/4 requests in #16217:
- ✅ Remove not special methods: `__cmp__`, `__div__`, `__nonzero__`, and
`__unicode__`.
- ✅ Add special methods: `__next__`, `__buffer__`, `__class_getitem__`,
`__mro_entries__`, `__release_buffer__`, and `__subclasshook__`.
- ✅ Support positional-only arguments.
- ❌ Add support for module functions `__dir__` and `__getattr__`. As
mentioned in the issue the check is scoped for methods rather than
module functions. I am hesitant to expand the scope of this check
without a discussion.
## Test Plan
- Manually confirmed each example file from the issue functioned as
expected.
- Ran cargo nextest to ensure `unexpected_special_method_signature` test
still passed.
Fixes#16217.
## Summary
Move class attribute (property, methods, variables) related cases in
AIR302_names to AIR302_class_attribute
## Test Plan
No functionality change. Test fixture is reogranized
Fixes false negative when slice bound uses length of string literal.
We were meant to check the following, for example. Given:
```python
text[:bound] if text.endswith(suffix) else text
```
We want to know whether:
- `suffix` is a string literal and `bound` is a number literal
- `suffix` is an expression and `bound` is
exactly `-len(suffix)` (as AST nodes, prior to evaluation.)
The issue is that negative number literals like `-10` are stored as
unary operators applied to a number literal in the AST. So when `suffix`
was a string literal but `bound` was `-len(suffix)` we were getting
caught in the match arm where `bound` needed to be a number. This is now
fixed with a guard.
Closes#16231
## Summary
Fixes#16189.
Only `sys.breakpointhook` is flagged by the upstream linter:
007a745c86/pylint/checkers/stdlib.py (L38)
but I think it makes sense to flag
[`__breakpointhook__`](https://docs.python.org/3/library/sys.html#sys.__breakpointhook__)
too, as suggested in the issue because it
> contain[s] the original value of breakpointhook [...] in case [it
happens] to get replaced with broken or alternative objects.
## Test Plan
New T100 test cases
## Summary
Added checks for subscript expressions on builtin classes as in FURB189.
The object is changed to use the collections objects and the types from
the subscript are kept.
Resolves#16130
> Note: Added some comments in the code explaining why
## Test Plan
- Added a subscript dict and list class to the test file.
- Tested locally to check that the symbols are changed and the types are
kept.
- No modifications changed on optional `str` values.
## Summary
Resolves#15859.
The rule now adds parentheses if the original call wraps an unary
expression and is:
* The left-hand side of a binary expression where the operator is `**`.
* The caller of a call expression.
* The subscripted of a subscript expression.
* The object of an attribute access.
The fix will also be marked as unsafe if there are any comments in its
range.
## Test Plan
`cargo nextest run` and `cargo insta test`.
## Summary
Resolves#13294, follow-up to #13882.
At #13882, it was concluded that a fix should not be offered for raw
strings. This change implements that. The five rules in question are now
no longer always fixable.
## Test Plan
`cargo nextest run` and `cargo insta test`.

The PR addresses the issue #16040 .
---
The logic used into the rule is the following:
Suppose to have an expression of the form
```python
if a cmp b:
c = d
```
where `a`,` b`, `c` and `d` are Python obj and `cmp` one of `<`, `>`,
`<=`, `>=`.
Then:
- `if a=c and b=d`
- if `<=` fix with `a = max(b, a)`
- if `>=` fix with `a = min(b, a)`
- if `>` fix with `a = min(a, b)`
- if `<` fix with `a = max(a, b)`
- `if a=d and b=c`
- if `<=` fix with `b = min(a, b)`
- if `>=` fix with `b = max(a, b)`
- if `>` fix with `b = max(b, a)`
- if `<` fix with `b = min(b, a)`
- do nothing, i.e., we cannot fix this case.
---
In total we have 8 different and possible cases.
```
| Case | Expression | Fix |
|-------|------------------|---------------|
| 1 | if a >= b: a = b | a = min(b, a) |
| 2 | if a <= b: a = b | a = max(b, a) |
| 3 | if a <= b: b = a | b = min(a, b) |
| 4 | if a >= b: b = a | b = max(a, b) |
| 5 | if a > b: a = b | a = min(a, b) |
| 6 | if a < b: a = b | a = max(a, b) |
| 7 | if a < b: b = a | b = min(b, a) |
| 8 | if a > b: b = a | b = max(b, a) |
```
I added them in the tests.
Please double-check that I didn't make any mistakes. It's quite easy to
mix up > and <.

## Summary
* fix ImportPathMoved / ProviderName misuse
* oncrete names, such as `["airflow", "config_templates",
"default_celery", "DEFAULT_CELERY_CONFIG"]`, should use `ProviderName`.
In contrast, module paths like `"airflow", "operators", "weekday", ...`
should use `ImportPathMoved`. Misuse may lead to incorrect detection.
## Test Plan
update test fixture
## Summary
Fixes#16007. The logic from the last fix for this (#9427) was
sufficient, it just wasn't being applied because `Attributes` sections
aren't expected to have nested sections. I just deleted the outer
conditional, which should hopefully fix this for all section types.
## Test Plan
New regression test, plus the existing D417 tests.
## Summary
Resolves#16082.
`UP036` will now also take into consideration whether or not a micro
version number is set:
* If a third element doesn't exist, the existing logic is preserved.
* If it exists but is not an integer literal, the check will not be
reported.
* If it is an integer literal but doesn't fit into a `u8`, the check
will be reported as invalid.
* Otherwise, the compared version is determined to always be less than
the target version when:
* The target's minor version is smaller than that of the comparator, or
* The operator is `<`, the micro version is 0, and the two minor
versions compare equal.
As this is considered a bugfix, it is not preview-gated.
## Test Plan
`cargo nextest run` and `cargo insta test`.

The index in subscript access like `d[*y]` will not be linted or
autofixed with parentheses, even when
`lint.ruff.parenthesize-tuple-in-subscript = true`.

This PR resolved#15772
Before PR:
```
def _(
this_is_fine: int = f(), # No error
this_is_not: list[int] = f() # B008: Do not perform function call `f` in argument defaults
): ...
@dataclass
class _:
this_is_not_fine: list[int] = f() # RUF009: Do not perform function call `f` in dataclass defaults
this_is_also_not: int = f() # RUF009: Do not perform function call `f` in dataclass defaults
```
After PR:
```
def _(

): ...
@dataclass
class _:

this_is_fine: int = f()
```
## Summary
Follow-up to #15984.
Previously, `PLE1310` would only report when the object is a literal:
```python
'a'.strip('//') # error
foo = ''
foo.strip('//') # no error
```
After this change, objects whose type can be inferred to be either `str`
or `bytes` will also be reported in preview.
## Test Plan
`cargo nextest run` and `cargo insta test`.
## Summary
Resolves#12321.
The physical-line-based `RUF054` checks for form feed characters that
are preceded by only tabs and spaces, but not any other characters,
including form feeds.
## Test Plan
`cargo nextest run` and `cargo insta test`.
## Summary
Follow-up to #16026.
Previously, the fix for this would be marked as unsafe, even though all
comments are preserved:
```python
# .pyi
T: TypeAlias = ( # Comment
int | str
)
```
Now it is safe: comments within the parenthesized range no longer affect
applicability.
## Test Plan
`cargo nextest run` and `cargo insta test`.

## Summary
Resolves#15968.
Previously, these would be considered violations:
```python
b''.strip('//')
''.lstrip('//', foo = "bar")
```
...while these are not:
```python
b''.strip(b'//')
''.strip('\\b\\x08')
```
Ruff will now not report when the types of the object and that of the
argument mismatch, or when there are extra arguments.
## Test Plan
`cargo nextest run` and `cargo insta test`.
