b24afb643c [ty] Support 'dangling' type(...) constructors (#22537)
## Summary

This PR adds support for 'dangling' `type(...)` constructors, e.g.:

```python
class Foo(type("Bar", ...)):
   ...
```

As opposed to:

```python
Bar = type("Bar", ...)
```

The former doesn't have a `Definition` since it doesn't get bound to a
place, so we instead need to store the `NodeIndex`. Per @MichaReiser's
suggestion, we can use a Salsa tracked struct for this.

ddd2fc7a90 [ty] Use "typeguard constraints" for two kinds of tuple narrowing (#22348)
## Summary

Since we've already filtered the union in these locations, it seems like
needless overhead to then intersect the previous union with the filtered
union. We know what that intersection will simplify to: it will simplify
to the filtered union. So rather than using a regular intersection-based
constraint, we can use a "typeguard constraint", which will just
directly replace the previous type with the new type instead of creating
an intersection.

## Test Plan

- Existing tests all pass
- The primer report should be clean

## Summary

<!-- What's the purpose of the change? What does it do, and why? -->
This PR fixes #20811 , current approach reverses the order in `BtreeSet`
however as pointed in
https://github.com/astral-sh/ruff/issues/20811#issuecomment-3398958832
here we cannot use I`IndexSet` to preserve config order since Settings
derives `CacheKey` which isn't implemented for `IndexSet`, another
approach to preserve the original order might be to use `Vec` however
lookup time complexity might get affected as a result.

<!-- How was it tested? -->

a697050a83 [ty] Fix stack overflow with recursive type aliases containing tuple … (#22543)
This fixes issue #2470 where recursive type aliases like `type
RecursiveT = int | tuple[RecursiveT, ...]` caused a stack overflow when
used in return type checking with constructors like `list()`.

The fix moves all type mapping processing for `UniqueSpecialization`
(and other non-EagerExpansion mappings) inside the `visitor.visit()`
closure. This ensures that if we encounter the same TypeAlias
recursively during type mapping, the cycle detector will properly detect
it and return the fallback value instead of recursing infinitely.

The key insight is that the previous code called
`apply_function_specialization` followed by another
`apply_type_mapping_impl` AFTER the visitor closure returned. At that
point, the TypeAlias was no longer in the visitor's `seen` set, so
recursive references would not be detected as cycles.

## Summary

The test I've added illustrates the fix. Copying it here too:

```python
from contextlib import contextmanager
from typing import Iterator
from typing_extensions import Self

class Base:
    @classmethod
    @contextmanager
    def create(cls) -> Iterator[Self]:
        yield cls()

class Child(Base): ...

with Base.create() as base:
    reveal_type(base)  # revealed: Base (after the fix, None before)

with Child.create() as child:
    reveal_type(child)  # revealed: Child (after the fix, None before)
```

Full disclosure: I've used LLMs for this PR, but the result is
thoroughly reviewed by me before submitting. I'm excited about my first
Rust contribution to Astral tools and will address feedback quickly.

Related to https://github.com/astral-sh/ty/issues/2030, I am working on
a fix for the TypeVar case also reported in that issue (by me)

99beabdde8 [ty] Fix false positive for bounded type parameters with NewType (#22542)
Fixes https://github.com/astral-sh/ty/issues/2467

When calling a method on an instance of a generic class with bounded
type parameters (e.g., `C[T: K]` where `K` is a NewType), ty was
incorrectly reporting: "Argument type `C[K]` does not satisfy upper
bound `C[T@C]` of type variable `Self`"

The issue was introduced by PR #22105, which moved the catch-all case
for NewType assignments that falls back to the concrete base type. This
case was moved before the TypeVar handling cases, so when checking `K <:
T@C` (where K is a NewType and T@C is a TypeVar with upper bound K):

1. The NewType fallback matched first
2. It delegated to `int` (K's concrete base type)
3. Then checked `int <: T@C`, which checks if `int` satisfies bound `K`
4. But `int` is not assignable to `K` (NewTypes are distinct from their
bases)

The fix moves the NewType fallback case after the TypeVar cases, so
TypeVar handling takes precedence. Now when checking `K <: T@C`, we use
the TypeVar case at line 828 which returns `false` for non-inferable
typevars - but this is correct because the *other* direction (`T@C <:
K`) passes, and for the overall specialization comparison both
directions are checked.

4abc5fe2f1 [ty] Add support for dynamic type() classes (#22291)
## Summary

This PR adds support for dynamic classes created via `type()`. The core
of the change is that `ClassLiteral` is now an enum:

```rust
pub enum ClassLiteral<'db> {
    /// A class defined via a `class` statement.
    Stmt(StmtClassLiteral<'db>),
    /// A class created via the functional form `type(name, bases, dict)`.
    Functional(FunctionalClassLiteral<'db>),
}
```

And, in turn, various methods on `ClassLiteral` like `body_scope` now
return `Option` or similar (and callers must adjust to that change in
signature).

Over time, we can expand the enum to include functional namedtuples,
etc. (I already have this working in a separate branch, and I believe it
slots in well.)

(I'd love help with the names -- I think `StmtClassLiteral` is kind of
lame. Maybe `DeclarativeClassLiteral`?)

Closes https://github.com/astral-sh/ty/issues/740.

e4ba29392b [ty] Fix __file__ type in completions to show str instead of str | None (#22510)
## Summary

The type inference system already correctly special-cases `__file__` to
return `str` for the current module (since the code is executing from an
existing file). However, the completion system was bypassing this logic
and pulling `__file__: str | None` directly from `types.ModuleType` in
typeshed.

This PR adds implicit module globals (like `__file__`, `__name__`, etc.)
with their correctly-typed values to completions, reusing the existing
`module_type_implicit_global_symbol` function that already handles the
special-casing.

Closes https://github.com/astral-sh/ty/issues/2445.

e15f88ff21 [ty] Fix contravariant type variable bound checking in specialization inference (#22488)
## Summary

Correctly handle upper bounds for contravariant type variables during
specialization inference. Previously, the type checker incorrectly
applied covariant subtyping rules, requiring the actual type to directly
satisfy the bound rather than checking for a valid intersection.

In contravariant positions, subtyping relationships are inverted. The
bug caused valid code like `f(x: Contra[str])` where `f` expects
`Contra[T: int]` to be incorrectly rejected, when it should solve `T` to
`Never` (the intersection of `int` and `str`).

Closes https://github.com/astral-sh/ty/issues/2427

## Details

- Added `is_contravariant()` helper to `TypeVarVariance` in
`variance.rs`
- Updated `SpecializationBuilder::infer_map_impl` in `generics.rs` to
treat bounds and constraints differently based on variance:
  * Skip immediate `ty <: bound` check for contravariant upper bounds
* Flip constraint check to `constraint <: ty` for contravariant
positions
- Added test case for bounded contravariant type variables in
`variance.md`
- All 308 mdtest cases pass & 150 ty_python_semantic unit tests pass

action | minor | `v7.1.6` → `v7.2.0` |

### Release Notes

<summary>astral-sh/setup-uv (astral-sh/setup-uv)</summary>

###
[`v7.2.0`](https://redirect.github.com/astral-sh/setup-uv/releases/tag/v7.2.0):
🌈 add outputs python-version and python-cache-hit

[Compare
Source](https://redirect.github.com/astral-sh/setup-uv/compare/v7.1.6...v7.2.0)

##### Changes

Among some minor typo fixes and quality of life features for developers
of actions the main feature of this release are new outputs:

- **python-version:** The Python version that was set (same content as
existing `UV_PYTHON`)
- **python-cache-hit:** A boolean value to indicate the Python cache
entry was found

While implementing this it became clear, that it is easier to handle the
Python binaries in a separate cache entry. The added benefit for users
is that the "normal" cache containing the dependencies can be used in
all runs no matter if these cache the Python binaries or not.

> \[!NOTE]\
> This release will invalidate caches that contain the Python binaries.
This happens a single time.

09ff3e7056 Set priority for prek to enable concurrent execution (#22506)
## Summary

prek allows you to set priorities, and can run tasks of the same
priority concurrently (e.g., we can run Ruff's Python formatting and
`cargo fmt` at the same time). On my machine, this takes `uvx prek run
-a` from 19.4s to 5.0s (~a 4x speed-up).

880513a013 Respect fmt: skip for multiple statements on same logical line (#22119)
This PR adjusts the logic for skipping formatting so that a `fmt: skip`
can affect multiple statements if they lie on the same line.

Specifically, a `fmt: skip` comment will now suppress all the statements
in the suite in which it appears whose range intersects the line
containing the skip directive. For example:

```python
x=[
'1'
];x=2 # fmt: skip
```

remains unchanged after formatting.

(Note that compound statements are somewhat special and were handled in
a previous PR - see #20633).


Closes #17331 and #11430.

Simplest to review commit by commit - the key diffs of interest are the
commit introducing the core logic, and the diff between the snapshots
introduced in the last commit (compared to the second commit).

# Implementation

On `main` we format a suite of statements by iterating through them. If
we meet a statement with a leading or trailing (own-line)`fmt: off`
comment, then we suppress formatting until we meet a `fmt: on` comment.
Otherwise we format the statement using its own formatting rule.

How are `fmt: skip` comments handled then? They are handled internally
to the formatting of each statement. Specifically, calling `.fmt` on a
statement node will first check to see if there is a trailing,
end-of-line `fmt: skip` (or `fmt: off`/`yapf: off`), and if so then
write the node with suppressed formatting.

In this PR we move the responsibility for handling `fmt: skip` into the
formatting logic of the suite itself. This is done as follows:

- Before beginning to format the suite, we do a pass through the
statements and collect the data of ranges with skipped formatting. More
specifically, we create a map with key given by the _first_ skipped
statement in a block and value a pair consisting of the _last_ skipped
statement and the _range_ to write verbatim.
- We iterate as before, but if we meet a statement that is a key in the
map constructed above, we pause to write the associated range verbatim.
We then advance the iterator to the last statement in the block and
proceed as before.

## Addendum on range formatting

We also had to make some changes to range formatting in order to support
this new behavior. For example, we want to make sure that

```python
<RANGE_START>x=1<RANGE_END>;x=2 # fmt: skip
```

formats verbatim, rather than becoming 

```python
x = 1;x=2 # fmt: skip
```

Recall that range formatting proceeds in two steps:
1. Find the smallest enclosing node containing the range AND that has
enough info to format the range (so it may be larger than you think,
e.g. a docstring has enclosing node given by the suite, not the string
itself.)
2. Carve out the formatted range from the result of formatting that
enclosing node.

We had to modify (1), since the suite knows how to format skipped nodes,
but nodes may not "know" they are skipped. To do this we altered the
`visit_body` bethod of the `FindEnclosingNode` visitor: now we iterate
through the statements and check for skipped ranges intersecting the
format range. If we find them, we return without descending. The result
is to consider the statement containing the suite as the enclosing node
in this case.

c88e1a0663 [ty] Avoid emitting Liskov repeated violations from grandparent to child (#22484)
## Summary

If parent violates LSP against grandparent, and child has the same
violation (but matches parent), we no longer flag the LSP violation on
child, since it can't be fixed without violating parent.

If parent violates LSP against grandparent, and child violates LSP
against both parent and grandparent, we emit two diagnostics (one for
each violation).

If parent violates LSP against grandparent, and child violates LSP
against parent (but not grandparent), we flag it.

f40c578ffb [ruff] document RUF100 trailing comment fix behavior (#22479)
## Summary
Ruff's `--fix` for `RUF100` can inadvertently remove trailing comments
(e.g., `pylint` or `mypy` suppressions) by interpreting them as
descriptions. This PR adds a "Conflict with other linters" section to
the rule documentation to clarify this behavior and provide the
double-hash (`# noqa # pylint`) workaround.

10eb3d52d5 [ty] Rank top-level module symbols above most other symbols
This makes it so, e.g., `os<CURSOR>` will suggest the top-level stdlib
`os` module even if there is an `os` symbol elsewhere in your project.

The way this is done is somewhat overwrought, but it's done to avoid
suggesting top-level modules over other symbols already in scope.

64117c1146 [ty] Improve completion ranking based on origin of symbols
Part of this was already done, but it was half-assed. We now look at the
search path that a symbol came from and centralize a symbol's origin
classification.

The preference ordering here is maybe not the right one, but we can
iterate as users give us feedback. Note also that the preference
ordering based on the origin is pretty low in the relevance sorting.
This means that other more specific criteria will and can override this.

This results in some nice improvements to our evaluation tasks.

2196ef3a33 [ty] Add package priority completion evaluation tasks
This commit adds two new tests. One checks that a symbol in the current
project gets priority over a symbol in the standard library. Another
checks that a symbol in a third party dependency gets priority over a
symbol in the standard library. We don't get either of these right
today.

Note that these comparisons are done ceteris paribus. A symbol from the
standard library could still be ranked above a symbol elsewhere.
(Although I believe currently this is somewhat rare.)

c36397031b [ty] Actually ignore hidden directories in completion evaluation
I apparently don't know how to use my own API. Previously,
we would skip, e.g., `.venv`, but still descend into it.

This was annoying in practice because I sometimes have an
environment in one of the truth task directories. The eval
command should ignore that entirely, but it ended up
choking on it without properly ignoring hidden files
and directories.

eef34958f9 [ty] More sensible sorting for results returned by all_symbols
Previously, we would only sort by name and file path (unless the symbol
refers to an entire module). This led to somewhat confusing ordering,
since the file path is absolute and can be anything.

Sorting by module name after symbol name gives a more predictable
ordering in common practice.

This is mostly just an improvement for debugging purposes, i.e., when
looking at the output of `all_symbols` directly. This mostly shouldn't
impact completion ordering since completions do their own ranking.

56862f8241 [ty] Refactor ranking
This moves the information we want to use to rank completions into
`Completion` itself. (This was the primary motivation for creating a
`CompletionBuilder` in the first place.)

The principal advantage here is that we now only need to compute the
relevance information for each completion exactly once. Previously, we
were computing it on every comparison, which might end up doing
redundant work for a not insignifcant number of completions.

The relevance information is also specifically constructed from the
builder so that, in the future, we might choose to short-circuit
construction if we know we'll never send it back to the client (e.g.,
its ranking is worse than the lowest ranked completion). But we don't
implement that optimization yet.

e9cc2f6f42 [ty] Refactor completion construction to use a builder
I want to be able to attach extra data to each `Completion`, but not
burden callers with the need to construct it. This commit helps get us
to that point by requiring callers to use a `CompletionBuilder` for
construction instead of a `Completion` itself.

I think this will also help in the future if it proves to be the case
that we can improve performance by delaying work until we actually build
a `Completion`, which might only happen if we know we won't throw it
out. But we aren't quite there yet.

This also lets us tighten things up a little bit and makes completion
construction less noisy. The downside is that callers no longer need to
consider "every" completion field.

There should not be any behavior changes here.

**What it does**
Checks for calls to `final()` that type checkers cannot interpret.
**Why is this bad?**
The `final()` function is designed to be used as a decorator. When called directly
as a function (e.g., `final(type(...))`), type checkers will not understand the
application of `final` and will not prevent subclassing.
**Example**
```python
from typing import final
# Incorrect: type checkers will not prevent subclassing
MyClass = final(type("MyClass", (), {}))
# Correct: use `final` as a decorator
@final
class MyClass: ...

**What it does**
Checks for enum classes that are also generic.
**Why is this bad?**
Enum classes cannot be generic. Python does not support generic enums:
attempting to create one will either result in an immediate `TypeError`
at runtime, or will create a class that cannot be specialized in the way
that a normal generic class can.
**Examples**
```python
from enum import Enum
from typing import Generic, TypeVar
T = TypeVar("T")
# error: enum class cannot be generic (class creation fails with `TypeError`)
class E[T](Enum):
A = 1
# error: enum class cannot be generic (class creation fails with `TypeError`)
class F(Enum, Generic[T]):
A = 1
# error: enum class cannot be generic -- the class creation does not immediately fail...
class G(Generic[T], Enum):
A = 1
# ...but this raises `KeyError`:
x: G[int]
```

**What it does**
Checks for dynamic class definitions (using `type()`) that have bases
which are unsupported by ty.
This is equivalent to [`unsupported-base`] but applies to classes created
via `type()` rather than `class` statements.
**Why is this bad?**
If a dynamically created class has a base that is an unsupported type
such as `type[T]`, ty will not be able to resolve the
[method resolution order] (MRO) for the class. This may lead to an inferior
understanding of your codebase and unpredictable type-checking behavior.
**Default level**
This rule is disabled by default because it will not cause a runtime error,
and may be noisy on codebases that use `type()` in highly dynamic ways.
**Examples**
```python
def factory(base: type[Base]) -> type:
# `base` has type `type[Base]`, not `type[Base]` itself
return type("Dynamic", (base,), {}) # error: [unsupported-dynamic-base]
```
