Closes https://github.com/astral-sh/ruff/issues/6788 by special casing
integer literals with attribute access — either retaining parenthesis
for literals with values (e.g. `int(7).denominator` to
`(7).denominator)` or leaving calls without values (e.g.
`int().denominator`) unchanged.
## Summary
Another drive-by change to remove unnecessary custom lexing. We just
need to know the parenthesized range, so we can use...
`parenthesized_range`. I've also updated `parenthesized_range` to
support nested parentheses.
## Test Plan
`cargo test`
## Summary
This is effectively #6608, but with additional tests.
We aren't properly handling parenthesized patterns, but that needs to be
dealt with separately as it's somewhat involved.
Closes#6555
## Summary
Follows up on
https://github.com/astral-sh/ruff/pull/6652#discussion_r1300871033 with
some modifications to the `PatternMatchAs` comment handling.
Specifically, any comments between the `as` and the end are now
formatted as dangling, and we now insert some newlines in the
appropriate places.
## Test Plan
`cargo test`
## Summary
Ensures that we retain the open-parenthesis comment in cases like:
```python
match pattern_comments:
case ( # leading
only_leading
):
...
```
Previously, this was treated as a leading comment on `only_leading`.
## Test Plan
`cargo test`
## Summary
This PR fixes the bug where the decorator parentheses weren't being considered
when computing the autofix for `ANN204`. The existing logic would only look
for balanced parentheses and not multiple pairs of parentheses.
The solution is to remove the logic to generate the autofix and use the
`Parameters` end range directly which includes the parentheses as well.
## Test Plan
Add test case for `ANN204` with decorator being called
fixes: #6790
## Summary
Given:
```python
def end_of_file():
if False:
return 1
x = 2 \
```
Then when searching for the end of the `x = 2` statement, we'd reach a
panic as we'd hit the last line (`\\`) and abort, since the universal
iterator doesn't return trailing newlines. Instead, we should just use
the end of the file as the fallback.
Closes https://github.com/astral-sh/ruff/issues/6787.
## Test Plan
`cargo test`
## Summary
Avoid `C417` for `lambda` with default and variadic parameters.
## Test Plan
`cargo test` and checking if it generates any autofix errors as test
cases
for `lambda` with default parameters already exists.
fixes: #6715
## Summary
This PR updates the lexer tests to use the snapshot testing framework.
It also
makes the following changes:
* Remove the use of macros in the lexer tests
* Use `test_case` for EOL tests
## Test Plan
```
cargo test --package ruff_python_parser --lib --all-features -- lexer::tests --no-capture
```
With https://github.com/django/django/pull/17181 merged, this removes an
odd edge case (tuple expression statements aka bogus trailing commas
after statements that turn them into a tuple without you noticing) that
we don't want to care about because the input code is ~wrong from the
similarity index. I've took this opportunity to update the revisions of
all projects we test.

## Summary
This PR adds a utility for transforming expressions via LibCST that
automatically wraps the expression in parentheses, applies a
user-provided transformation, then strips the parentheses from the
generated code. LibCST can't parse arbitrary expression ranges, since
some expressions may require parenthesization in order to be parsed
properly. For example:
```python
option = (
'{name}={value}'
.format(nam=name, value=value)
)
```
In this case, the expression range is:
```python
'{name}={value}'
.format(nam=name, value=value)
```
Which isn't valid on its own. So, instead, we add "fake" parentheses
around the expression.
We were already doing this in a few places, so this is mostly
formalizing and DRYing up that pattern.
Closes https://github.com/astral-sh/ruff/issues/6720.
## Summary
For imports, we enforce that there's _at least_ one empty line after an
import (assuming the next statement is _not_ an import), but allow up to
two at the module level.
Closes https://github.com/astral-sh/ruff/issues/6760.
## Test Plan
`cargo test`
## Summary
The isolation group for unused imports was relying on
`checker.semantic().current_statement()`, which isn't valid for that
rule, since it runs over the _scope_, not the statement. Instead, we
need to lookup the isolation group based on the `NodeId` of the
statement.
Our tests didn't catch this, because we mostly have cases that look like
this:
```python
if TYPE_CHECKING:
import shelve
import importlib
```
In this case, the two fixes to remove the two unused imports are
considered overlapping (since we delete the _full_ line, and the two
_full_ lines touch, and we consider exactly-adjacent fixes to be
overlapping), and so they don't run in a single pass due to the
non-overlapping-fixes requirement. That is: the isolation groups aren't
required for this case. They are, however, required for cases like:
```python
if TYPE_CHECKING:
import shelve
import importlib
```
...where the fixes don't overlap.
Closes https://github.com/astral-sh/ruff/issues/6758.
## Test Plan
`cargo test`
`IOError` is special, it is not actually a lint but an error before
linting. I'm not entirely sure how to document it since it does not
match the general lint rule pattern (`Checks that the file can be read
in its entirety.` is imho worse).
I added the in my experience two most common reasons for io errors on
unix systems and linked two tutorials on how to fix them.

## Summary
I noticed this in the ecosystem CI check from
https://github.com/astral-sh/ruff/pull/6742. If we include source code
directly in a diagnostic, we need to be careful to avoid rendering
multi-line diagnostics or even excessively long diagnostics.
## Test Plan
`cargo test`
## Summary
This PR is a follow-up to the suggestion in
https://github.com/astral-sh/ruff/pull/6345#discussion_r1285470953 to
use a single stack to store all statements and expressions, rather than
using separate vectors for each, which gives us something closer to a
full-fidelity chain. (We can then generalize this concept to include all
other AST nodes too.)
This is in part made possible by the removal of the hash map from
`&Stmt` to `StatementId` (#6694), which makes it much cheaper to store
these using a single interface (since doing so no longer introduces the
requirement that we hash all expressions).
I'll follow-up with some profiling, but a few notes on how the data
requirements have changed:
- We now store a `BranchId` for every expression, not just every
statement, so that's an extra `u32`.
- We now store a single `NodeId` on every snapshot, rather than separate
`StatementId` and `ExpressionId` IDs, so that's one fewer `u32` for each
snapshot.
- We're probably doing a few more lookups in general, since any calls to
`current_statement()` etc. now have to iterate up the node hierarchy
until they identify the first statement.
## Test Plan
`cargo test`
## Summary
Avoid attempting to rewrite `import matplotlib.pyplot` as `import
matplotlib.pyplot as plt`. We can't support these right now, since we
don't track references at the attribute level (like
`matplotlib.pyplot`).
Closes https://github.com/astral-sh/ruff/issues/6719.
## Summary
Given:
```python
from sys import *
exit(0)
```
We can't add `exit` to `from sys import *`, so we should just ignore it.
Ideally, we'd just resolve `exit` in the first place (since it's
imported from `from sys import *`), but as long as we don't support
wildcard imports, this is more consistent.
Closes https://github.com/astral-sh/ruff/issues/6718.
## Test Plan
`cargo test`
Avoid the nesting in a macro by using the new `WithNodeLevel` to
`PyFormatter` deref. No changes otherwise.
I wanted to follow this up with quickly fixing the typeshed empty line
rules but they turned out a lot more complex than i had anticipated.

**Summary** A common pattern in the code used to be
```rust
if statements.len() != 1 {
return;
}
use_single_entry(statements[0])?;
```
which can be better expressed as
```rust
let [statement] = statements else {
return;
};
use_single_entry(statements)?;
```
Direct indexing can cause panics if you don't manually take care of
checking the length, while matching (such as if-let or let-else) can
never panic.
This isn't a complete refactor, i've just removed some of the obvious
cases. I've specifically looked for `.len() != 1` and fixed those.
**Test Plan** No functional changes
## Summary
We're using LibCST to ensure that we return the full parenthesized range
of an expression, for display purposes. We can just use
`parenthesized_range` which is more efficient and removes one LibCST
dependency.
## Test Plan
`cargo test`
