## Summary
Mark `FURB180`'s fix as unsafe if the class already has base classes.
This is because the base classes might validate the other base classes
(like `typing.Protocol` does) or otherwise alter runtime behavior if
more base classes are added.
## Test Plan
The existing snapshot test covers this case already.

## Summary
Closes#17226.
This PR updates the `FAST003` rule to correctly handle [FastAPI class
dependencies](https://fastapi.tiangolo.com/tutorial/dependencies/classes-as-dependencies/).
Specifically, if a path parameter is declared in either:
- a `pydantic.BaseModel` used as a dependency, or
- the `__init__` method of a class used as a dependency,
then `FAST003` will no longer incorrectly report it as unused.
FastAPI allows a shortcut when using annotated class dependencies -
`Depends` can be called without arguments, e.g.:
```python
class MyParams(BaseModel):
my_id: int
@router.get("/{my_id}")
def get_id(params: Annotated[MyParams, Depends()]): ...
```
This PR ensures that such usage is properly supported by the linter.
Note: Support for dataclasses is not included in this PR. Let me know if
you’d like it to be added.
## Test Plan
Added relevant test cases to the `FAST003.py` fixture.
## Summary
This currently doesn't work because the benchmark changes the working
directory. Also updates the process name to make it easier to compare
two local ty binaries.
This PR implements template strings (t-strings) in the parser and
formatter for Ruff.
Minimal changes necessary to compile were made in other parts of the code (e.g. ty, the linter, etc.). These will be covered properly in follow-up PRs.
## Summary
Allow a typevar to be callable if it is bound to a callable type, or
constrained to callable types.
I spent some time digging into why this support didn't fall out
naturally, and ultimately the reason is that we look up `__call__` on
the meta type (since its a dunder), and our implementation of
`Type::to_meta_type` for `Type::Callable` does not return a type with
`__call__`.
A more general solution here would be to have `Type::to_meta_type` for
`Type::Callable` synthesize a protocol with `__call__` and return an
intersection with that protocol (since for a type to be callable, we
know its meta-type must have `__call__`). That solution could in
principle also replace the special-case handling of `Type::Callable`
itself, here in `Type::bindings`. But that more general approach would
also be slower, and our protocol support isn't quite ready for that yet,
and handling this directly in `Type::bindings` is really not bad.
Fixes https://github.com/astral-sh/ty/issues/480
## Test Plan
Added mdtests.
This PR adds initial support for listing all attributes of
an object. It is exposed through a new `all_members`
routine in `ty_extensions`, which is in turn used to test
the functionality.
The purpose of listing all members is for code
completion. That is, given a `object.<CURSOR>`, we
would like to list all available attributes on
`object`.

Summary
--
This is the last main difference between the `OldDiagnostic` and
`Message`
types, so attaching a `SourceFile` to `OldDiagnostic` should make
combining the
two types almost trivial.
Initially I updated the remaining rules without access to a `Checker` to
take a
`&SourceFile` directly, but after Micha's suggestion in
https://github.com/astral-sh/ruff/pull/18356#discussion_r2113281552, I
updated all of these calls to take a
`LintContext` instead. This new type is a thin wrapper around a
`RefCell<Vec<OldDiagnostic>>`
and a `SourceFile` and now has the `report_diagnostic` method returning
a `DiagnosticGuard` instead of `Checker`.
This allows the same `Drop`-based implementation to be used in cases
without a `Checker` and also avoids a lot of intermediate allocations of
`Vec<OldDiagnostic>`s.
`Checker` now also contains a `LintContext`, which it defers to for its
`report_diagnostic` methods, which I preserved for convenience.

## Summary
- Convert tests demonstrating our resilience to malformed/absent
`version` fields in `pyvenf.cfg` files to mdtests. Also make them more
expansive.
- Convert the regression test I added in
https://github.com/astral-sh/ruff/pull/18157 to an mdtest
- Add comments next to unit tests that cannot be converted to mdtests
(but where it's not obvious why they can't) so I don't have to do this
exercise again 😄
- In `site_packages.rs`, factor out the logic for figuring out where we
expect the system-installation `site-packages` to be. Currently we have
the same logic twice.
## Test Plan
`cargo test -p ty_python_semantic`
## Summary
This change was based on a mis-reading of a comment in typeshed, and a
wrong assumption about what was causing a test failure in a prior PR.
Reverting it doesn't cause any tests to fail.
## Test Plan
Existing tests.
## Summary
Resolves [#513](https://github.com/astral-sh/ty/issues/513).
Callable types are now considered to be disjoint from nominal instance
types where:
* The class is `@final`, and
* Its `__call__` either does not exist or is not assignable to `(...) ->
Unknown`.
## Test Plan
Markdown tests.

## Summary
Partially implement https://github.com/astral-sh/ty/issues/538,
```py
from pathlib import Path
def setup_test_project(registry_name: str, registry_url: str, project_dir: str) -> Path:
pyproject_file = Path(project_dir) / "pyproject.toml"
pyproject_file.write_text("...", encoding="utf-8")
```
As no return statement is defined in the function `setup_test_project`
with annotated return type `Path`, we provide the following diagnosis :
- error[invalid-return-type]: Function **always** implicitly returns
`None`, which is not assignable to return type `Path`
with a subdiagnostic :
- note: Consider changing your return annotation to `-> None` or adding a `return` statement
## Test Plan
mdtests with snapshots to capture the subdiagnostic. I have to mention
that existing snapshots were modified since they now fall in this
category.

## Summary
<!-- What's the purpose of the change? What does it do, and why? -->
Add utility functions `generate_import_edit` and
`generate_remove_and_runtime_import_edit` to generate the fix needed for
the airflow rules.
1. `generate_import_edit` is for the cases where the member name has
changed. (e.g., `airflow.datasts.Dataset` to `airflow.sdk.Asset`) It's
just extracted from the original logic
2. `generate_remove_and_runtime_import_edit` is for cases where the
member name has not changed. (e.g.,
`airflow.operators.pig_operator.PigOperator` to
`airflow.providers.apache.pig.hooks.pig.PigCliHook`) This is newly
introduced. As it introduced runtime import, I mark it as an unsafe fix.
Under the hook, it tried to find the original import statement, remove
it, and add a new import fix

Summary

It's a bit late in the refactoring process, but I think there are still
a couple of PRs left before getting rid of this type entirely, so I
thought it would still be worth doing.
This PR is just a quick rename with no other changes.

## Summary
Adds coverage of using set(...) in addition to `{...} in
SingleItemMembershipTest.
Fixes#15792
(and replaces the old PR #15793)
<!-- What's the purpose of the change? What does it do, and why? -->
## Test Plan
Updated unit test and snapshot.
Steps to reproduce are in the issue linked above.
<!-- How was it tested? -->
Previously, completions were based on just returning every identifier
parsed in the current Python file. In this commit, we change it to
identify an expression under the cursor and then return all symbols
available to the scope containing that expression.
This is still returning too much, and also, in some cases, not enough.
Namely, it doesn't really take the specific context into account other
than scope. But this does improve on the status quo. For example:
def foo(): ...
def bar():
def fast(): ...
def foofoo(): ...
f<CURSOR>
When asking for completions here, the LSP will no longer include `fast`
as a possible completion in this context.
Ref https://github.com/astral-sh/ty/issues/86
This is analogous to the existing `Tokens::after` method. Its
implementation is almost identical.
We plan to use this for looking at the tokens immediately before the
cursor when fetching completions.

## Summary
Implements `use-maxsplit-arg` (`PLC0207`)
https://pylint.readthedocs.io/en/latest/user_guide/messages/convention/use-maxsplit-arg.html
> Emitted when accessing only the first or last element of str.split().
The first and last element can be accessed by using str.split(sep,
maxsplit=1)[0] or str.rsplit(sep, maxsplit=1)[-1] instead.
This is part of https://github.com/astral-sh/ruff/issues/970
## Test Plan
`cargo test`
Additionally compared Ruff output to Pylint:
```
pylint --disable=all --enable=use-maxsplit-arg crates/ruff_linter/resources/test/fixtures/pylint/missing_maxsplit_arg.py
cargo run -p ruff -- check crates/ruff_linter/resources/test/fixtures/pylint/missing_maxsplit_arg.py --no-cache --select PLC0207

## Summary
This PR add the `fix safety` section for rule `B006` in
`mutable_argument_default.rs` for #15584
When applying this rule for fixes, certain changes may alter the
original logical behavior. For example:
before:
```python
def cache(x, storage=[]):
storage.append(x)
return storage
print(cache(1)) # [1]
print(cache(2)) # [1, 2]
```
after:
```python
def cache(x, storage=[]):
storage.append(x)
return storage
print(cache(1)) # [1]
print(cache(2)) # [2]
```

Snapshot tests
There were many fields in `Signature` and friends that really had more
to do with how a signature was being _used_ — how it was looked up,
details about an individual call site, etc. Those fields more properly
belong in `Bindings` and friends.
This is a pure refactoring, and should not affect any tests or ecosystem
projects.
I started on this journey in support of
https://github.com/astral-sh/ty/issues/462. It seemed worth pulling out
as a separate PR.
One major concrete benefit of this refactoring is that we can now use
`CallableSignature` directly in `CallableType`. (We can't use
`CallableSignature` directly in that `Type` variant because signatures
are not currently interned.)
