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.

See:
https://github.com/astral-sh/ruff/issues/7455#issuecomment-1741107573.

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.

## Test Plan

Snapshot tests from
https://github.com/PyCQA/bandit/blob/1.7.5/examples/weak_cryptographic_key_sizes.py.

Ignore TODO tags in `commented-out-code` (#7523)
## Summary

Extend the `task-tags` checking logic to ignore TODO tags (with or
without parentheses). For example,

```python
# TODO(tjkuson): Rewrite in Rust
```

is no longer flagged as commented-out code.

Closes #7031.

I also updated the documentation to inform users that the rule is prone
to false positives like this!

now corrected.

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.).

similar rules wherever possible. To be consistent this PR expands PGH002
to do the same.

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 {
     ...

There is no need for additional `let/if let` checks on `ExprCall` in
downstream rules. Found a few older rules which still did this while
working on something else. This PR removes the redundant check from
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

also loosens the enforcement around assignments like: `__all__ =

though we can't analyze the members, since we _know_ they evaluate to a
`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)

Don't suggest replacing `builtin.open()` with `Path.open()` if the latter doesn't support all options (#7637)
**Summary** Check that `closefd` and `opener` aren't being used with
`builtin.open()` before suggesting `Path.open()` because pathlib doesn't
support these arguments.

Closes #7620

**Test Plan** New cases in the fixture.

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)
## Summary

This is whitespace as per `is_python_whitespace`, and right now it tends
to lead to panics in the formatter. Seems reasonable to treat it as
whitespace in the `SimpleTokenizer` too.

Closes .https://github.com/astral-sh/ruff/issues/7624.

Charlie Marsh 17ceb5dcb3
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.

## Test Plan

No change in compatibility.
