## Summary
This PR adds symbols introduced by `match` statements.
There are three patterns that introduces new symbols:
* `as` pattern
* Sequence pattern
* Mapping pattern
The recursive nature of the visitor makes sure that all symbols are
added.
## Test Plan
Add test case for all types of patterns that introduces a symbol.
## Summary
This PR adds definition for augmented assignment. This is similar to
annotated assignment in terms of implementation.
An augmented assignment should also record a use of the variable but
that's a TODO for now.
## Test Plan
Add test case to validate that a definition is added.
## Summary
As suggested by @MichaReiser in
https://github.com/astral-sh/ruff/pull/12886#pullrequestreview-2237679793,
this adds an exemption to `RUF027` for `fastAPI` paths, which require
template strings rather than eagerly evaluated f-strings.
## Test Plan
I added a fixture that causes Ruff to emit a false-positive error on
`main` but no longer does with this PR.
Extend the `UseDefMap` to also track which constraints (provided by e.g.
`if` tests) apply to each visible definition.
Uses a custom `BitSet` and `BitSetArray` to track which constraints
apply to which definitions, while keeping data inline as much as
possible.
## Summary
This PR is a pure refactor to simplify some of the logic for `RUF027`.
This will make it easier to file some followup PRs to help reduce the
false positives from this rule. I'm separating the refactor out into a
separate PR so it's easier to review, and so I can double-check from the
ecosystem report that this doesn't have any user-facing impact.
## Test Plan
`cargo test -p ruff_linter --lib`
## Summary
This PR adds support for adding symbols and definitions for function and
lambda parameters to the semantic index.
### Notes
* The default expression of a parameter is evaluated in the enclosing
scope (not the type parameter or function scope).
* The annotation expression of a parameter is evaluated in the type
parameter scope if they're present other in the enclosing scope.
* The symbols and definitions are added in the function parameter scope.
### Type Inference
There are two definitions `Parameter` and `ParameterWithDefault` and
their respective `*_definition` methods on the type inference builder.
These methods are preferred and are re-used when checking from a
different region.
## Test Plan
Add test case for validating that the parameters are defined in the
function / lambda scope.
### Benchmark update
Validated the difference in diagnostics for benchmark code between
`main` and this branch. All of them are either directly or indirectly
referencing one of the function parameters. The diff is in the PR description.
This adds the `fast-api-unused-path-parameter` lint rule, as described
in #12632.
I'm still pretty new to rust, so the code can probably be improved, feel
free to tell me if there's any changes i should make.
Also, i needed to add the `add_parameter` edit function, not sure if it
was in the scope of the PR or if i should've made another one.
If a builtin is conditionally shadowed by a global, we didn't correctly
fall back to builtins for the not-defined-in-globals path (see added
test for an example.)
List and set comprehensions using `async for` cannot be replaced with
underlying generators; this PR modifies C419 to skip such
comprehensions.
Closes#12891.
## Summary
Occasionally, we receive bug reports that imports in `src` directories
aren't correctly detected. The root of the problem is that we default to
`src = ["."]`, so users have to set `src = ["src"]` explicitly. This PR
extends the default to cover _both_ of them: `src = [".", "src"]`.
Closes https://github.com/astral-sh/ruff/issues/12454.
## Test Plan
I replicated the structure described in
https://github.com/astral-sh/ruff/issues/12453, and verified that the
imports were considered sorted, but that adding `src = ["."]` showed an
error.
