## Summary
- Expand some docs where they're unclear about the motivation, or assume
some knowledge that hasn't been introduced yet
- Add more links to external docs
- Rename PYI063 from `PrePep570PositionalArgument` to
`Pep484StylePositionalOnlyParameter`
- Rename the file `parenthesize_logical_operators.rs` to
`parenthesize_chained_operators.rs`, since the rule is called
`ParenthesizeChainedOperators`, not `ParenthesizeLogicalOperators`
## Test Plan
`cargo test`
## Summary
These rules were implemented in January, have been very stable, and have
no open issues about them. They were highly requested by the community
prior to being implemented. Let's stabilise them!
## Test Plan
Ecosystem check on this PR.
## Summary
Follow-up to #14371, this PR simplifies the visitor logic for list
expressions to remove the state management. We just need to make sure
that we visit the nested expressions using the `QuoteAnnotator` and not
the `Generator`. This is similar to what's being done for binary
expressions.
As per the
[grammar](https://typing.readthedocs.io/en/latest/spec/annotations.html#grammar-token-expression-grammar-annotation_expression),
list expressions can be present which can contain other type expressions
(`Callable`):
```
| <Callable> '[' <Concatenate> '[' (type_expression ',')+
(name | '...') ']' ',' type_expression ']'
(where name must be a valid in-scope ParamSpec)
| <Callable> '[' '[' maybe_unpacked (',' maybe_unpacked)*
']' ',' type_expression ']'
```
## Test Plan

`cargo test`
The ecosystem results are all correct, but for `Airflow` the rule is not
relevant due to the use of overloading (and is marked as unsafe
correctly).

This PR adds corrected handling of list expressions to the `Visitor`
implementation of `QuotedAnnotator` in `flake8_type_checking::helpers`.
Closes#14368
Fix: #13934
## Summary
Current implementation has a bug when the current annotation contains a
string with single and double quotes.
TL;DR: I think these cases happen less than other use cases of Literal.
So instead of fixing them we skip the fix in those cases.
One of the problematic cases:
```
from typing import Literal
from third_party import Type
def error(self, type1: Type[Literal["'"]]):
pass
```
The outcome is:
```
- def error(self, type1: Type[Literal["'"]]):
+ def error(self, type1: "Type[Literal[''']]"):
```
While it should be:
```
"Type[Literal['\'']"
```
The solution in this case is that we check if there’s any quotes same as
the quote style we want to use for this Literal parameter then escape
that same quote used in the string.
Also this case is not uncommon to have:
<https://grep.app/search?current=2&q=Literal["'>
But this can get more complicated for example in case of:
```
- def error(self, type1: Type[Literal["\'"]]):
+ def error(self, type1: "Type[Literal[''']]"):
```
Here we escaped the inner quote but in the generated annotation it gets
removed. Then we flip the quote style of the Literal paramter and the
formatting is wrong.
In this case the solution is more complicated.
1. When generating the string of the source code preserve the backslash.
2. After we have the annotation check if there isn’t any escaped quote
of the same type we want to use for the Literal parameter. In this case
check if we have any `’` without `\` before them. This can get more
complicated since there can be multiple backslashes so checking for only
`\’` won’t be enough.
Another problem is when the string contains `\n`. In case of
`Type[Literal["\n"]]` we generate `'Type[Literal["\n"]]'` and both
pyright and mypy reject this annotation.

## Test Plan
I added test cases for the original code in the reported issue and two
more cases for backslash and new line.

Follow-up to #14287 : when checking that `name` is the same as `as_name`
in `import name as as_name`, we do not need to first do an early return
if `'.'` is found in `name`.
This PR handles a panic that occurs when applying unsafe fixes if a user
inserts a required import (I002) that has a "useless alias" in it, like
`import numpy as numpy`, and also selects PLC0414 (useless-import-alias)
In this case, the fixes alternate between adding the required import
statement, then removing the alias, until the recursion limit is
reached. See linked issue for an example.
Closes#14283

This PR improves the fix for `PYI055` to be able to handle nested and
mixed type unions.
It also marks the fix as unsafe when comments are present.

`pytest-raises-too-broad (PT011)` should be raised when
`expected_exception` is provided as a keyword argument.
```python
def test_foo():
with pytest.raises(ValueError): # raises PT011
raise ValueError("Can't divide 1 by 0")
# This is minor but a valid pytest.raises call
with pytest.raises(expected_exception=ValueError): # doesn't raise PT011 but should
raise ValueError("Can't divide 1 by 0")
