## 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.
Hi all!
## Summary
Fix a typo.
## Test Plan
URL was tested with curl.
Not much left to say, except that I originally saw this issue on the
blog post: https://astral.sh/blog/ruff-v0.5.0
Not sure how it is related to the CHANGELOG.md file, so the post might
need fixing as well.
Thanks for this incredible tool!

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
Follow-up to https://github.com/astral-sh/ruff/pull/12129 to remove the
`demisto/content` from ecosystem checks. The previous PR removed it from
the deprecated script which I didn't notice until recently.
## Test Plan
Ecosystem comment
## 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:---
yield,x
---
/Users/dhruv/playground/ruff/src/play.py:1:1: E275 Missing whitespace after keyword
|
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`.
## Summary
Unfortunately `demisto/content` uses an explicit `select` for `E999`, so
it will _always_ fail in preview. And they're on a fairly old version.
I'd like to keep checking it, but seems easiest for now to just disable
it.
In response, I've added a few new repos.

## Summary
This patch inverts the defaults for
[pytest-fixture-incorrect-parentheses-style
(PT001)](https://docs.astral.sh/ruff/rules/pytest-fixture-incorrect-parentheses-style/)
and [pytest-incorrect-mark-parentheses-style
(PT003)](https://docs.astral.sh/ruff/rules/pytest-incorrect-mark-parentheses-style/)
to prefer dropping superfluous parentheses.
Presently, Ruff defaults to adding superfluous parentheses on pytest
mark and fixture decorators for documented purpose of consistency; for
example,
```diff
import pytest
-@pytest.mark.foo
+@pytest.mark.foo()
def test_bar(): ...
```
This behaviour is counter to the official pytest recommendation and
diverges from the flake8-pytest-style plugin as of version 2.0.0 (see
https://github.com/m-burst/flake8-pytest-style/issues/272). Seeing as
either default satisfies the documented benefit of consistency across a
codebase, it makes sense to change the behaviour to be consistent with
pytest and the flake8 plugin as well.
This change is breaking, so is gated behind preview (at least under my
understanding of Ruff versioning). The implementation of this gating
feature is a bit hacky, but seemed to be the least disruptive solution
without performing invasive surgery on the `#[option()]` macro.
Related to #8796.
### Caveat
Whilst updating the documentation, I sought to reference the pytest
recommendation to drop superfluous parentheses, but couldn't find any
official instruction beyond it being a revealed preference within the
pytest documentation code examples (as well as the linked issues from a
core pytest developer). Thus, the wording of the preference is
deliberately timid; it's to cohere with pytest rather than follow an
explicit guidance.
## Test Plan
`cargo nextest run`
I also ran
```sh
cargo run -p ruff -- check crates/ruff_linter/resources/test/fixtures/flake8_pytest_style/PT001.py --no-cache --diff --select PT001
```
and compared against it with `--preview` to verify that the default does
change under preview (I also repeated this with `echo
'[tool.ruff]\npreview = true' > pyproject.toml` to verify that it works
with a configuration file).

## Summary
Implement mutable-contextvar-default (B039) which was added to
flake8-bugbear in https://github.com/PyCQA/flake8-bugbear/pull/476.
This rule is similar to [mutable-argument-default
(B006)](https://docs.astral.sh/ruff/rules/mutable-argument-default) and
[function-call-in-default-argument
(B008)](https://docs.astral.sh/ruff/rules/function-call-in-default-argument),
except that it checks the `default` keyword argument to
`contextvars.ContextVar`.
```
B039.py:19:26: B039 Do not use mutable data structures for ContextVar defaults
|
18 | # Bad
19 | ContextVar("cv", default=[])
| ^^ B039
20 | ContextVar("cv", default={})
21 | ContextVar("cv", default=list())
|
= help: Replace with `None`; initialize with `.set()` after checking for `None`
```
In the upstream flake8-plugin, this rule is written expressly as a
corollary to B008 and shares much of its logic. Likewise, this
implementation reuses the logic of the Ruff implementation of B008,
namely
f765d19402/crates/ruff_linter/src/rules/flake8_bugbear/rules/function_call_in_argument_default.rs (L104-L106)
and
f765d19402/crates/ruff_linter/src/rules/flake8_bugbear/rules/mutable_argument_default.rs (L106)
Thus, this rule deliberately replicates B006's and B008's heuristics.
For example, this rule assumes that all functions are mutable unless
otherwise qualified. If improvements are to be made to B039 heuristics,
they should probably be made to B006 and B008 as well (whilst trying to
match the upstream implementation).
This rule does not have an autofix as it is unknown where the ContextVar
next used (and it might not be within the same file).
Closes#12054
## Test Plan
`cargo nextest run`
## Summary
This adds a fix for the `duplicate-bases` rule that removes the
duplicate base from the class definition.
## Test Plan
`cargo nextest run duplicate_bases`, `cargo insta review`.
