Force parentheses for power operations in unary expressions (#7955)
## Summary

E.g., given `-10**100`, reformat as `-(10**100)`.

Treat type aliases as typing-only expressions (#7968)
## Summary

Given `type RecordOrThings = Record | int | str`, the right-hand side
won't be evaluated at runtime. Same goes for `Record` in `type
RecordCallback[R: Record] = Callable[[R], None]`. This PR modifies the
visitation logic to treat them as typing-only.

Add `cell` field to JSON output format (#7664)
## Summary

This PR adds a new `cell` field to the JSON output format which
indicates the Notebook cell this diagnostic (and fix) belongs to. It
also updates the location for the diagnostic and fixes as per the
`NotebookIndex`. It will be used in the VSCode extension to display the
diagnostic in the correct cell.

The diagnostic and edit start and end source locations are translated
for the notebook as per the `NotebookIndex`. The end source location for
an edit needs some special handling.

### Edit end location

To understand this, the following context is required:

1. Visible lines in Jupyter Notebook vs JSON array strings: The newline
is part of the string in the JSON format. This means that if there are 3
visible lines in a cell where the last line is empty then the JSON would
contain 2 strings in the source array, both ending with a newline:

**JSON format:**
```json
[
	"# first line\n",
	"# second line\n",
]
```

**Notebook view:**
```python
1 # first line
2 # second line
3
```

2. If an edit needs to remove an entire line including the newline, then
the end location would be the start of the next row.

To remove a statement in the following code:
```python
import os
```

The edit would be:
```
start: row 1, col 1
end: row 2, col 1
```

Now, here's where the problem lies. The notebook index doesn't have any
information for row 2 because it doesn't exists in the actual notebook.
The newline was added by Ruff to concatenate the source code and it's
removed before writing back. But, the edit is computed looking at that
newline.

This means that while translating the end location for an edit belong to
a Notebook, we need to check if both the start and end location belongs
to the same cell. If not, then the end location should be the first
character of the next row and if so, translate that back to the last
character of the previous row. Taking the above example, the translated
location for Notebook would be:
```
start: row 1, col 1
end: row 1, col 10
```

## Test Plan

Add test cases for notebook output in the JSON format and update
existing snapshots.

Format comment before parameter default correctly (#7870)
**Summary** Handle comment before the default values of function
parameters correctly by inserting a line break instead of space after
the equals sign where required.

```python
def f(
    a = # parameter trailing comment; needs line break
    1,
    b =
    # default leading comment; needs line break
    2,
    c = ( # the default leading can only be end-of-line with parentheses; no line break
        3
    ),
    d = (
        # own line leading comment with parentheses; no line break
        4
    )
)
```

Fixes #7603

**Test Plan** Added the different cases and one more complex case as
fixtures.

Fix `E251` false positive inside f-strings (#7894)
## Summary

This PR fixes the bug where the rule `E251` was being triggered on a equal token
inside a f-string which was used in the context of debug expressions.

For example, the following was being flagged before the fix:

```python
print(f"{foo = }")
```

But, now it is not. This leads to false negatives such as:

```python
print(f"{foo(a = 1)}")
```

One solution would be to know if the opened parentheses was inside a f-string or
not. If it was then we can continue flagging until it's closed. If not, then we
should not flag it.

## Test Plan

Add new test cases and check that they don't raise any false positives.

fix edge case with PIE804 (#7922)
## Summary

`foo(**{})` was an overlooked edge case for `PIE804` which introduced a
crash within the Fix, introduced in #7884.

I've made it so that `foo(**{})` turns into `foo()` when applied with
`--fix`, but is that desired/expected? 🤔 Should we just ignore instead?

Drop formatting specific rules from the default set (#7900)
Closes https://github.com/astral-sh/ruff/issues/7572

Drops formatting specific rules from the default rule set as they
conflict with formatters in general (and in particular, conflict with
our formatter). Most of these rules are in preview, but the removal of
`line-too-long` and `mixed-spaces-and-tabs` is a change to the stable
rule set.

## Example

The following no longer raises `E501`
```
echo "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx = 1" | ruff check -
```

Remove per-diagnostic check for fixability (#7919)
## Summary

Throughout the codebase, we have this pattern:

```rust
let mut diagnostic = ...
if checker.patch(Rule::UnusedVariable) {
    // Do the fix.
}
diagnostics.push(diagnostic)
```

This was helpful when we computed fixes lazily; however, we now compute
fixes eagerly, and this is _only_ used to ensure that we don't generate
fixes for rules marked as unfixable.

We often forget to add this, and it leads to bugs in enforcing
`--unfixable`.

This PR instead removes all of these checks, moving the responsibility
of enforcing `--unfixable` up to `check_path`. This is similar to how
@zanieb handled the `--extend-unsafe` logic: we post-process the
diagnostics to remove any fixes that should be ignored.

add autofix for `PLR1714` (#7910)
## Summary

Add autofix for `PLR1714` using tuples.

If added complexity is desired, we can lean into the `set` part by doing
some kind of builtin check on all of the comparator elements for
starters, since we otherwise don't know if something's hashable.

## Test Plan

`cargo test`, and manually.

Allow bindings to be created and referenced within annotations (#7885)
## Summary

Given:

```python
baz: Annotated[
    str,
    [qux for qux in foo],
]
```

We treat `baz` as `BindingKind::Annotation`, to ensure that references
to `baz` are marked as unbound. However, we were _also_ treating `qux`
as `BindingKind::Annotation`, which meant that the load in the
comprehension _also_ errored.

Promote some rules to "always" fixable (#7840)
## Summary

This PR upgrades some rules from "sometimes" to "always" fixes, now that
we're getting ready to ship support in the CLI. The focus here was on
identifying rules for which the diagnostic itself is high-confidence,
and the fix itself is too (assuming that the diagnostic is correct).
This is _unlike_ rules that _may_ be a false positive, like those that
(e.g.) assume an object is a dictionary when you call `.values()` on it.

Specifically, I upgraded:

- A bunch of rules that only apply to `.pyi` files.
- Rules that rewrite deprecated imports or aliases.
- Some other misc. rules, like: `empty-print-string`, `unused-noqa`,
`getattr-with-constant`.

Open to feedback on any of these.

Rename applicability levels to `Safe`, `Unsafe`, and `Display` (#7843)
After working with the previous change in
https://github.com/astral-sh/ruff/pull/7821 I found the names a bit
unclear and their relationship with the user-facing API muddied. Since
the applicability is exposed to the user directly in our JSON output, I
think it's important that these names align with our configuration
options. I've replaced `Manual` or `Never` with `Display` which captures
our intent for these fixes (only for display). Here, we create room for
future levels, such as `HasPlaceholders`, which wouldn't fit into the
`Always`/`Sometimes`/`Never` levels.

Unlike https://github.com/astral-sh/ruff/pull/7819, this retains the
flat enum structure which is easier to work with.

changed by `--output-file`).

Update CLI to respect fix applicability (#7769)
Rebase of https://github.com/astral-sh/ruff/pull/5119 authored by
@evanrittenhouse with additional refinements.

## Changes

- Adds `--unsafe-fixes` / `--no-unsafe-fixes` flags to `ruff check`
- Violations with unsafe fixes are not shown as fixable unless opted-in
- Fix applicability is respected now
    - `Applicability::Never` fixes are no longer applied
    - `Applicability::Sometimes` fixes require opt-in
    - `Applicability::Always` fixes are unchanged
- Hints for availability of `--unsafe-fixes` added to `ruff check`
output

## Examples

Check hints at hidden unsafe fixes
```
❯ ruff check example.py --no-cache --select F601,W292
example.py:1:14: F601 Dictionary key literal `'a'` repeated
example.py:2:15: W292 [*] No newline at end of file
Found 2 errors.
[*] 1 fixable with the `--fix` option (1 hidden fix can be enabled with the `--unsafe-fixes` option).
```

We could add an indicator for which violations have hidden fixes in the
future.

Check treats unsafe fixes as applicable with opt-in
```
❯ ruff check example.py --no-cache --select F601,W292 --unsafe-fixes
example.py:1:14: F601 [*] Dictionary key literal `'a'` repeated
example.py:2:15: W292 [*] No newline at end of file
Found 2 errors.
[*] 2 fixable with the --fix option.
```

Also can be enabled in the config file

```
❯ cat ruff.toml
unsafe-fixes = true
```

And opted-out per invocation

```
❯ ruff check example.py --no-cache --select F601,W292 --no-unsafe-fixes
example.py:1:14: F601 Dictionary key literal `'a'` repeated
example.py:2:15: W292 [*] No newline at end of file
Found 2 errors.
[*] 1 fixable with the `--fix` option (1 hidden fix can be enabled with the `--unsafe-fixes` option).
```

Diff does not include unsafe fixes
```
❯ ruff check example.py --no-cache --select F601,W292 --diff
--- example.py
+++ example.py
@@ -1,2 +1,2 @@
 x = {'a': 1, 'a': 1}
-print(('foo'))
+print(('foo'))
\ No newline at end of file

```

Unless there is opt-in
```
❯ ruff check example.py --no-cache --select F601,W292 --diff --unsafe-fixes
--- example.py
+++ example.py
@@ -1,2 +1,2 @@
-x = {'a': 1}
-print(('foo'))
+x = {'a': 1, 'a': 1}

```

https://github.com/astral-sh/ruff/pull/7790 will improve the diff
messages following this pull request

Similarly, `--fix` and `--fix-only` require the `--unsafe-fixes` flag to
apply unsafe fixes.

Report precise location for invalid conversion flag (#7809)
## Summary

This PR updates the parser definition to use the precise location when reporting
an invalid f-string conversion flag error.

Taking the following example code:
```python
f"{foo!x}"
```

On earlier version,
```
Error: f-string: invalid conversion character at byte offset 6
```

Now,
```
Error: f-string: invalid conversion character at byte offset 7
```

This becomes more useful when there's whitespace between `!` and the flag value
although that is not valid but we can't detect that now.

## Test Plan

As mentioned above.

## Summary

This PR resolves an issue raised in

an f-string that exceeds the line length _even if_ the resultant code is
_shorter_ than the current code.

As part of this change, I've also refactored and extracted some common
logic we use around "ensuring a fix isn't breaking the line length
rules".

Fix issues with SIM101 (adjacent isinstance() calls) (#7798)
- Only trigger for immediately adjacent isinstance() calls with the same
target
- Preserve order of or conditions

Two existing tests changed:
- One was incorrectly reordering the or conditions, and is now correct.
- Another was combining two non-adjacent isinstance() calls. It's safe
enough in that example,
but this isn't safe to do in general, and it feels low-value to come up
with a heuristic for
when it is safe, so it seems better to not combine the calls in that
case.

as well but I missed the part:

> [..]
> * **If in “format specifier mode” (see step 3), an opening brace ({)

> * If not in “format specifier mode” (see step 3), an opening brace ({)
or a closing brace (}) that is not immediately followed by another
opening/closing brace.

Enable formatting for Jupyter notebooks (#7749)
## Summary

This PR enables `ruff format` to format Jupyter notebooks.

Most of the work is contained in a new `format_source` method that

source required formatting, or `None` otherwise.

Closes https://github.com/astral-sh/ruff/issues/7598.

## Test Plan

Ran `cat foo.py | cargo run -p ruff_cli -- format --stdin-filename
Untitled.ipynb`; verified that the console showed a reasonable error:

```console
warning: Failed to read notebook Untitled.ipynb: Expected a Jupyter Notebook, which must be internally stored as JSON, but this file isn't valid JSON: EOF while parsing a value at line 1 column 0

Avoid printing continuations within import identifiers (#7744)
## Summary

It turns out that _some_ identifiers can contain newlines --
specifically, dot-delimited import identifiers, like:
```python
import foo\
    .bar
```

At present, we print all identifiers verbatim, which causes us to retain
the `\` in the formatted output. This also leads to violating some debug
assertions (see the linked issue, though that's a symptom of this
formatting failure).

This PR adds detection for import identifiers that contain newlines, and
formats them via `text` (slow) rather than `source_code_slice` (fast) in
those cases.

Closes https://github.com/astral-sh/ruff/issues/7734.

**Summary** The `value` of the `FStringMiddle` for `f"""}}ab"""` is

string this gives us false indices causing exploding fixes for PLE251
rules (PLE2510, PLE2512, PLE2513, PLE2514, PLE2515). Instead, we now use

is a symptom of having warnings that aren't themselves diagnostics. If
we want this to be user-facing, we should add a diagnostic for it!

## Test Plan

Ran `cargo run -p ruff_cli -- check foo.py -n` on:

```python
from typing import Annotated

Annotated[int]

Perform insertions before replacements (#7739)
## Summary

If we have, e.g.:

```python
sum((
            factor.dims for factor in bases
        ), [])
```

We generate three edits: two insertions (for the `operator` and
`functools` imports), and then one replacement (for the `sum` call
itself). We need to ensure that the insertions come before the
replacement; otherwise, the edits will appear overlapping and
out-of-order.

Consume the escaped Windows newline (`\r\n`) for `FStringMiddle` (#7722)
## Summary

This PR fixes a bug where if a Windows newline (`\r\n`) character was
escaped, then only the `\r` was consumed and not `\n` leading to an
unterminated string error.

## Test Plan

Add new test cases to check the newline escapes.

Remove escaped mac/windows eol from AST string value (#7724)
## Summary

This PR fixes the bug where the value of a string node type includes the
escaped mac/windows newline character.

Note that the token value still includes them, it's only removed when
parsing the string content.

## Test Plan

Add new test cases for the string node type to check that the escapes
aren't being included in the string value.

Ignore overlong pragma comments when enforcing linter line length (#7692)
## Summary

This PR modifies the `line-too-long` and `doc-line-too-long` rules to
ignore lines that are too long due to the presence of a pragma comment
(e.g., `# type: ignore` or `# noqa`). That is, if a line only exceeds
the limit due to the pragma comment, it will no longer be flagged as
"too long". This behavior mirrors that of the formatter, thus ensuring
that we don't flag lines under E501 that the formatter would otherwise
avoid wrapping.

As a concrete example, given a line length of 88, the following would
_no longer_ be considered an E501 violation:

```python
# The string literal is 88 characters, including quotes.
"shape:shape:shape:shape:shape:shape:shape:shape:shape:shape:shape:shape:shape:shape:sh"  # type: ignore
```

This, however, would:

```python
# The string literal is 89 characters, including quotes.
"shape:shape:shape:shape:shape:shape:shape:shape:shape:shape:shape:shape:shape:shape:sha"  # type: ignore
```

In addition to mirroring the formatter, this also means that adding a
pragma comment (like `# noqa`) won't _cause_ additional violations to
appear (namely, E501). It's very common for users to add a `# type:
ignore` or similar to a line, only to find that they then have to add a
suppression comment _after_ it that was required before, as in `# type:
ignore # noqa: E501`.

Improve performance of `commented-out-code` (~50-80%) (#7706)
## Summary

This PR implements a variety of optimizations to improve performance of
the Eradicate rule, which always shows up in all-rules benchmarks and
bothers me. (These improvements are not hugely important, but it was
kind of a fun Friday thing to spent a bit of time on.)

The improvements include:

- Doing cheaper work first (checking for some explicit substrings
upfront).
- Using `aho-corasick` to speed an exact substring search.
- Merging multiple regular expressions using a `RegexSet`.
- Removing some unnecessary `\s*` and other pieces from the regular
expressions (since we already trim strings before matching on them).

## Test Plan

I benchmarked this function in a standalone crate using a variety of
cases. Criterion reports that this version is up to 80% faster, and
almost every case is at least 50% faster:

which will always be consistent with the tokens.

Track fix isolation in `unnecessary-pass` (#7715)
## Summary

This wasn't necessary in the past, since we _only_ applied this rule to
bodies that contained two statements, one of which was a `pass`. Now
that it applies to any `pass` in a block with multiple statements, we
can run into situations in which we remove both passes, and so need to
apply the fixes in isolation.

feat(rules): implement `flake8-bandit` `S505` (#7703)
Part of #1646.

## Summary

Implement `S505`
([`weak_cryptographic_key`](https://bandit.readthedocs.io/en/latest/plugins/b505_weak_cryptographic_key.html))
rule from `bandit`.

For this rule, `bandit` [reports the issue
with](https://github.com/PyCQA/bandit/blob/1.7.5/bandit/plugins/weak_cryptographic_key.py#L47-L56):
- medium severity for DSA/RSA < 2048 bits and EC < 224 bits
- high severity for DSA/RSA < 1024 bits and EC < 160 bits

Since Ruff does not handle severities for `bandit`-related rules, we
could either report the issue if we have lower values than medium
severity, or lower values than high one. Two reasons led me to choose
the first option:
- a medium severity issue is still a security issue we would want to
report to the user, who can then decide to either handle the issue or
ignore it
- `bandit` [maps the EC key algorithms to their respective key lengths
in
bits](https://github.com/PyCQA/bandit/blob/1.7.5/bandit/plugins/weak_cryptographic_key.py#L112-L133),
but there is no value below 160 bits, so technically `bandit` would
never report medium severity issues for EC keys, only high ones

Another consideration is that as shared just above, for EC key
algorithms, `bandit` has a mapping to map the algorithms to their
respective key lengths. In the implementation in Ruff, I rather went
with an explicit list of EC algorithms known to be vulnerable (which
would thus be reported) rather than implementing a mapping to retrieve
the associated key length and comparing it with the minimum value.

fix(rules): improve S507 detection (#7661)
## Summary

Follow-up on https://github.com/astral-sh/ruff/pull/7528 that improves
detections of mis-usages of policy in `paramiko`.

First commit applies the same fix as in `bandit`
(https://github.com/PyCQA/bandit/pull/1064), as `paramiko` supports
passing both a class and a class instance for the policy in
`set_missing_host_key_policy`
(8e389c7766/paramiko/client.py (L171-L191)).

Second commit improve the detection of `paramiko` import paths that
trigger a violation, as `AutoAddPolicy`, `WarningPolicy` and `SSHClient`
are not only exposed in `paramiko.client`, but also in `paramiko`
(66117732de/paramiko/__init__.py (L121-L164)).

Include radix base prefix in large number representation (#7700)
## Summary

When lexing a number like `0x995DC9BBDF1939FA` that exceeds our small
number representation, we were only storing the portion after the base
(in this case, `995DC9BBDF1939FA`). When using that representation in
code generation, this could lead to invalid syntax, since
`995DC9BBDF1939FA)` on its own is not a valid integer.

This PR modifies the code to store the full span, including the radix
prefix.

Add `explicit-preview-rules` to toggle explicit selection of preview rules (#7390)
Closes #7434 

Replaces the `PREVIEW` selector (removed in #7389) with a configuration
option `explicit-preview-rules` which requires selectors to use exact
rule codes for all preview rules. This allows users to enable preview
without opting into all preview rules at once.

Always prefer double quotes for docstrings and triple-quoted srings (#7680)
## Summary

At present, `quote-style` is used universally. However, [PEP
8](https://peps.python.org/pep-0008/) and [PEP
257](https://peps.python.org/pep-0257/) suggest that while either single
or double quotes are acceptable in general (as long as they're
consistent), docstrings and triple-quoted strings should always use
double quotes. In our research, the vast majority of Ruff users that
enable the `flake8-quotes` rules only enable them for inline strings
(i.e., non-triple-quoted strings).

Additionally, many Black forks (like Blue and Pyink) use double quotes
for docstrings and triple-quoted strings.

Our decision for now is to always prefer double quotes for triple-quoted
strings (which should include docstrings). Based on feedback, we may
consider adding additional options (e.g., a `"preserve"` mode, to avoid
changing quotes; or a `"multiline-quote-style"` to override this).

Closes https://github.com/astral-sh/ruff/issues/7615.

Extend pragma comment cases (#7687)
## Summary

Extends the pragma comment detection in the formatter to support
case-insensitive `noqa` (as supposed by Ruff), plus a variety of other
pragmas (`isort:`, `nosec`, etc.).

Also extracts the detection out into the trivia crate so that we can
reuse it in the linter (see:

`PGH002`, which checks for use of deprecated `logging.warn` calls, did
not check for calls made on the attribute `warn` yet. Since

chore: remove redundant `Expr::Call` checks (#7678)
## Summary

As we bind the `ast::ExprCall` in the big `match expr` in
`expression.rs`
```rust
Expr::Call(
    call @ ast::ExprCall {

these rules.

Add `lint` section to Ruff configuration
## Summary

This PR adds a new `lint` section to the configuration that groups all linter-specific settings. The existing top-level configurations continue to work without any warning because the `lint.*` settings are experimental. 

The configuration merges the top level and `lint.*` settings where the settings in `lint` have higher precedence (override the top-level settings). The reasoning behind this is that the settings in `lint.` are more specific and more specific settings should override less specific settings.

I decided against showing the new `lint.*` options on our website because it would make the page extremely long (it's technically easy to do, just attribute `lint` with `[option_group`]). We may want to explore adding an `alias` field to the `option` attribute and show the alias on the website along with its regular name. 

## Test Plan

* I added new integration tests
* I verified that the generated `options.md` is identical
* Verified the default settings in the playground

`list`.

Add `Expr::Name` checks to rules which use `is_logger_candidate` (#7521)
## Summary

Expands several rules to also check for `Expr::Name` values. As they
would previously not consider:
```python
from logging import error

error("foo")
```
as potential violations
```python
import logging

logging.error("foo")
```
as potential violations leading to inconsistent behaviour. 

The rules impacted are:

- `BLE001`
- `TRY400`
- `TRY401`
- `PLE1205`
- `PLE1206`
- `LOG007`
- `G001`-`G004`
- `G101`
- `G201`
- `G202`

Use 1-based cell indices consistently for Notebooks (#7662)
## Summary

This PR fixes the bug where the cell indices displayed in the `--diff` output
and the ones in the normal output were different. This was due to the fact that
the `--diff` output was using the `enumerate` function to iterate over
the cells which starts at 0.

## Test Plan

Ran the following command with and without the `--diff` flag:

```console
cargo run --bin ruff -- check --no-cache --isolated ~/playground/ruff/notebooks/test.ipynb

Formatter and parser refactoring (#7569)
I got confused and refactored a bit, now the naming should be more
consistent. This is the basis for the range formatting work.

Chages:
* `format_module` -> `format_module_source` (format a string)
* `format_node` -> `format_module_ast` (format a program parsed into an
AST)
* Added `parse_ok_tokens` that takes `Token` instead of `Result<Token>`
* Call the source code `source` consistently
* Added a `tokens_and_ranges` helper
* `python_ast` -> `module` (because that's the type)

Implement our own small-integer optimization (#7584)
## Summary

This is a follow-up to #7469 that attempts to achieve similar gains, but
without introducing malachite. Instead, this PR removes the `BigInt`
type altogether, instead opting for a simple enum that allows us to
store small integers directly and only allocate for values greater than
`i64`:

```rust
/// A Python integer literal. Represents both small (fits in an `i64`) and large integers.
#[derive(Clone, PartialEq, Eq, Hash)]
pub struct Int(Number);

#[derive(Debug, Clone, PartialEq, Eq, Hash)]
pub enum Number {
    /// A "small" number that can be represented as an `i64`.
    Small(i64),
    /// A "large" number that cannot be represented as an `i64`.
    Big(Box<str>),
}

impl std::fmt::Display for Number {
    fn fmt(&self, f: &mut std::fmt::Formatter<'_>) -> std::fmt::Result {
        match self {
            Number::Small(value) => write!(f, "{value}"),
            Number::Big(value) => write!(f, "{value}"),
        }
    }
}
```

We typically don't care about numbers greater than `isize` -- our only
uses are comparisons against small constants (like `1`, `2`, `3`, etc.),
so there's no real loss of information, except in one or two rules where
we're now a little more conservative (with the worst-case being that we
don't flag, e.g., an `itertools.pairwise` that uses an extremely large
value for the slice start constant). For simplicity, a few diagnostics
now show a dedicated message when they see integers that are out of the
supported range (e.g., `outdated-version-block`).

An additional benefit here is that we get to remove a few dependencies,
especially `num-bigint`.

Treat form feed as whitespace in `SimpleTokenizer` (#7626)

Preserve newlines after nested compound statements (#7608)
## Summary

Given:
```python
if True:
    if True:
        pass
    else:
        pass
        # a

        # b
        # c

else:
    pass
```

We want to preserve the newline after the `# c` (before the `else`).
However, the `last_node` ends at the `pass`, and the comments are
trailing comments on the `pass`, not trailing comments on the
`last_node` (the `if`). As such, when counting the trailing newlines on
the outer `if`, we abort as soon as we see the comment (`# a`).

This PR changes the logic to skip _all_ comments (even those with
newlines between them). This is safe as we know that there are no
"leading" comments on the `else`, so there's no risk of skipping those
accidentally.

Closes https://github.com/astral-sh/ruff/issues/7602.

the first position is the yield type, so we can ignore other positions.

Avoid reordering mixed-indent-level comments after branches (#7609)
## Summary

Given:

```python
if True:
    if True:
        if True:
            pass

        #a
            #b
        #c
else:
    pass
```

When determining the placement of the various comments, we compute the
indentation depth of each comment, and then compare it to the depth of
the previous statement. It turns out this can lead to reordering
comments, e.g., above, `#b` is assigned as a trailing comment of `pass`,
and so gets reordered above `#a`.

This PR modifies the logic such that when we compute the indentation
depth of `#b`, we limit it to at most the indentation depth of `#a`. In
other words, when analyzing comments at the end of branches, we don't
let successive comments go any _deeper_ than their preceding comments.

Closes https://github.com/astral-sh/ruff/issues/7602.

Ignore blank lines between comments when counting newlines-after-imports (#7607)
## Summary

Given:

```python
# -*- coding: utf-8 -*-
import random

# Defaults for arguments are defined here
# args.threshold = None;


logger = logging.getLogger("FastProject")
```

We want to count the number of newlines after `import random`, to ensure
that there's _at least one_, but up to two.

Previously, we used the end range of the statement (then skipped
trivia); instead, we need to use the end of the _last comment_. This is
similar to #7556.

Truncate to one empty line in stub files (#7558)

Fix gitignore to not ignore files that are required (#7538)
It is apparently possible to add files to the git index, even if they
are part of the gitignore (see e.g.
https://stackoverflow.com/questions/45400361/why-is-gitignore-not-ignoring-my-files,
even though it's strange that the gitignore entries existed before the
files were added, i wouldn't know how to get them added in that case). I
ran
```
git rm -r --cached .
```
then change the gitignore not actually ignore those files with the
exception of
`crates/ruff_cli/resources/test/fixtures/cache_mutable/source.py`, which
is actually a generated file.

Allow up to two newlines after trailing clause body comments (#7557)
## Summary

The number of newlines after a trailing comment in a clause body needs
to follow the usual rules -- so, up to two for top-level, up to one for
nested, etc.

For example, Black preserves both newlines after `# comment` here:

```python
if True:
    pass

    # comment


else:
    pass
```

But it truncates to one newline here:

```python
if True:
    if True:
        pass
        # comment


    else:
        pass
else:
    pass
```

Fix instability in trailing clause body comments (#7556)
## Summary

When we format the trailing comments on a clause body, we check if there
are any newlines after the last statement; if not, we insert one.

This logic didn't take into account that the last statement could itself
have trailing comments, as in:

```python
if True:
    pass

    # comment
else:
    pass
```

We were thus inserting a newline after the comment, like:

```python
if True:
    pass

    # comment

else:
    pass
```

In the context of function definitions, this led to an instability,
since we insert a newline _after_ a function, which would in turn lead
to the bug above appearing in the second formatting pass.

Closes https://github.com/astral-sh/ruff/issues/7465.

## Test Plan

`cargo test`

Small improvement in `transformers`, but no regressions.

Treat parameters-with-newline as empty in function formatting (#7550)
## Summary

If a function has no parameters (and no comments within the parameters'
`()`), we're supposed to wrap the return annotation _whenever_ it
breaks. However, our `empty_parameters` test didn't properly account for
the case in which the parameters include a newline (but no other
content), like:

```python
def get_dashboards_hierarchy(
) -> Dict[Type['BaseDashboard'], List[Type['BaseDashboard']]]:
    """Get hierarchy of dashboards classes.

    Returns:
        Dict of dashboards classes.
    """
    dashboards_hierarchy = {}
```

This PR fixes that detection. Instead of lexing, it now checks if the
parameters itself is empty (or if it contains comments).

Move `Settings` and `ResolverSettings` to `ruff_workspace`
## Summary

## Stack Summary

This stack splits `Settings` into `FormatterSettings` and `LinterSettings` and moves it into `ruff_workspace`. This change is necessary to add the `FormatterSettings` to `Settings` without adding `ruff_python_formatter` as a dependency to `ruff_linter` (and the linter should not contain the formatter settings). 

A quick overview of our settings struct at play:

* `Options`: 1:1 representation of the options in the `pyproject.toml` or `ruff.toml`.  Used for deserialization.
* `Configuration`: Resolved `Options`, potentially merged from multiple configurations (when using `extend`). The representation is very close if not identical to the `Options`.
* `Settings`: The resolved configuration that uses a data format optimized for reading. Optional fields are initialized with their default values. Initialized by `Configuration::into_settings` .

The goal of this stack is to split `Settings` into tool-specific resolved `Settings` that are independent of each other. This comes at the advantage that the individual crates don't need to know anything about the other tools. The downside is that information gets duplicated between `Settings`. Right now the duplication is minimal (`line-length`, `tab-width`) but we may need to come up with a solution if more expensive data needs sharing.

This stack focuses on `Settings`. Splitting `Configuration` into some smaller structs is something I'll follow up on later. 

## PR Summary

Use strict sorted and union for NoQA mapping insertion (#7531)
## Summary

This PR fixes the way NoQA range is inserted to the `NoqaMapping`.

Previously, the way the mapping insertion logic worked was as follows:
1. If the range which is to be inserted _touched_ the previous range, meaning
that the end of the previous range was the same as the start of the new
range, then the new range was added in addition to the previous range.
2. Else, if the new range intersected the previous range, then the previous
   range was replaced with the new _intersection_ of the two ranges.

The problem with this logic is that it does not work for the following case:
```python
assert foo, \
    """multi-line
    string"""
```

Now, the comments cannot be added to the same line which ends with a continuation
character. So, the `NoQA` directive has to be added to the next line. But, the
next line is also a triple-quoted string, so the `NoQA` directive for that line
needs to be added to the next line. This creates a **union** pattern instead of an
**intersection** pattern.

But, only union doesn't suffice because (1) means that for the edge case where
the range touch only at the end, the union won't take place.

### Solution

1. Replace '<=' with '<' to have a _strict_ insertion case
2. Use union instead of intersection

## Test Plan

Add a new test case. Run the test suite to ensure that nothing is broken.

### Integration

1. Make a `test.py` file with the following contents:

    ```python
    assert foo, \
        """multi-line
        string"""
    ```

2. Run the following command:

    ```console
	$ cargo run --bin ruff -- check --isolated --no-cache --select=F821 test.py
	/Users/dhruv/playground/ruff/fstring.py:1:8: F821 Undefined name `foo`
    Found 1 error.
    ```

3. Use `--add-noqa`:

    ```console
	$ cargo run --bin ruff -- check --isolated --no-cache --select=F821 --add-noqa test.py
    Added 1 noqa directive.
    ```

4. Check that the NoQA directive was added in the correct position:

    ```python
    assert foo, \
        """multi-line
        string"""  # noqa: F821
    ```

5. Run the `check` command to ensure that the NoQA directive is respected:

    ```console
	$ cargo run --bin ruff -- check --isolated --no-cache --select=F821 test.py
    ```

feat(rules): implement `flake8-bandit` `S507` (`ssh_no_host_key_verification`) (#7528)
Part of #1646.

## Summary

Implement `S507`
([`ssh_no_host_key_verification`](https://bandit.readthedocs.io/en/latest/plugins/b507_ssh_no_host_key_verification.html))
rule from `bandit`.

## Test Plan

Snapshot test from
https://github.com/PyCQA/bandit/blob/1.7.5/examples/no_host_key_verification.py,
with several additions to test for more cases (most notably passing the
parameter as a named argument).

[`refurb`] Implement `unnecessary-enumerate` (`FURB148`) (#7454)
## Summary

Implement
[`no-ignored-enumerate-items`](https://github.com/dosisod/refurb/blob/master/refurb/checks/builtin/no_ignored_enumerate.py)
as `unnecessary-enumerate` (`FURB148`).

The auto-fix considers if a `start` argument is passed to the
`enumerate()` function. If only the index is used, then the suggested
fix is to pass the `start` value to the `range()` function. So,

```python
for i, _ in enumerate(xs, 1):
    ...
```

becomes

```python
for i in range(1, len(xs)):
    ...
```

If the index is ignored and only the value is ignored, and if a start
value greater than zero is passed to `enumerate()`, the rule doesn't
produce a suggestion. I couldn't find a unanimously accepted best way to
iterate over a collection whilst skipping the first n elements. The rule
still triggers, however.

Related to #1348.

Add dangling comment handling for `lambda` expressions (#7493)
## Summary

This PR adds dangling comment handling for `lambda` expressions. In
short, comments around the `lambda` and the `:` are all considered
dangling. Comments that come between the `lambda` and the `:` may be
moved after the colon for simplicity (this is an odd position for a
comment anyway), unless they also precede the lambda parameters, in
which case they're formatted before the parameters.

Closes https://github.com/astral-sh/ruff/issues/7470.

Add dangling comment handling to dictionary key-value pairs (#7495)

`:`.

Fix stylist indentation with a formfeed (#7489)
**Summary** In python, a formfeed is technically undefined behaviour
(https://docs.python.org/3/reference/lexical_analysis.html#indentation):
> A formfeed character may be present at the start of the line; it will
be ignored for
> the indentation calculations above. Formfeed characters occurring
elsewhere in the
> leading whitespace have an undefined effect (for instance, they may
reset the space
> count to zero).

In practice, they just reset the indentation:


df8b3a46a7/Parser/tokenizer.c (L1819-L1821)
a41bb2733f/crates/ruff_python_parser/src/lexer.rs (L664-L667)

The stylist didn't handle formfeeds previously and would produce invalid
indents. The remedy is to cut everything before a form feed.

https://github.com/astral-sh/ruff/issues/7455#issuecomment-1722458825

rule

Respect parentheses for precedence in `await` (#7468)
## Summary

We were using `Parenthesize::IfBreaks` universally for `await`, but
dropping parentheses can change the AST due to precedence. It turns out
that Black's rules aren't _exactly_ the same as operator precedence
(e.g., they leave parentheses around `await ([1, 2, 3])`, although they
aren't strictly required).

Closes https://github.com/astral-sh/ruff/issues/7467.

Refactor `tab-indentation` as a token-based rule (#7435)
## Summary

This PR updates the `W191` (`tab-indentation`) rule from a line-based to
a token-based rule.

Earlier, the rule used the `triple_quoted_string_ranges` from the
indexer to skip over any lines _inside_ a triple-quoted string. This was the only
use of the ranges. These ranges were extracted through the tokens, so instead
we can directly use the newline tokens to perform the check.

This would also mean that we can remove the `triple_quoted_string_ranges` from
the indexer but I'll hold that off until we have a better idea on #7326
but I don't think it would be a problem to remove it.

This will also fix #7379 once PEP 701 changes are merged.

Avoid extra parentheses in unary expressions (#7428)
## Summary

This PR applies a similar fix to unary expressions as in
https://github.com/astral-sh/ruff/pull/7424. Specifically, we only need
to parenthesize the entire operator if the operand itself doesn't have
parentheses, and requires parentheses.

Closes https://github.com/astral-sh/ruff/issues/7423.

## Test Plan

`cargo test`

[`flake8-logging`] Implement `LOG002`: `invalid-get-logger-argument` (#7399)
## Summary

This PR implements a new rule for `flake8-logging` plugin that checks
for
`logging.getLogger` calls with either `__file__` or `__cached__` as the
first
argument and generates a suggested fix to use `__name__` instead.

Refer: #7248

## Test Plan

Add test cases and `cargo test`

Use CommentRanges in backwards lexing (#7360)
## Summary

The tokenizer was split into a forward and a backwards tokenizer. The
backwards tokenizer uses the same names as the forwards ones (e.g.
`next_token`). The backwards tokenizer gets the comment ranges that we
already built to skip comments.
