## Summary
When adding an enum literal `E = Literal[Color.RED]` to a union which
already contained a subtype of that enum literal(!), we were previously
not simplifying the union correctly. My assumption is that our property
tests didn't catch that earlier, because the only possible non-trivial
subytpe of an enum literal that I can think of is `Any & E`. And in
order for that to be detected by the property tests, it would have to
randomly generate `Any & E | E` and then also compare that with `E` on
the other side (in an equivalence test, or the subtyping-antisymmetry
test).

## Test Plan
* Added a regression test.
* I also ran the property tests for a while, but probably not for two
months worth of daily CI runs.

## Summary
Closes#18349
After this change:
- All deprecated rules are deselected by default
- They are only selected if the user specifically selects them by code,
e.g. `--select UP038`
- Thus, `--select ALL --select UP --select UP0` won't select the
deprecated rule UP038
- Documented the change in version policy. From now on, deprecating a
rule should increase the minor version
## Test Plan
Integration tests in "integration_tests.rs"
Also tested with a temporary test package:
```
~> ../../ruff/target/debug/ruff.exe check --select UP038
warning: Rule `UP038` is deprecated and will be removed in a future release.
warning: Detected debug build without --no-cache.

I put this all in one PR to make it easier to double check with @Lee-W
before we merge this. I also made a few minor documentation changes and
updated one error message that I want to make sure are okay. But for the
most part this just moves the rules from `RuleGroup::Preview` to
`RuleGroup::Stable`!
Fixes#17749
This stabilizes the behavior introduced in #16565 which (roughly) tries
to match an import like `import a.b.c` to an actual directory path
`a/b/c` in order to label it as first-party, rather than simply looking
for a directory `a`.
Mainly this affects the sorting of imports in the presence of namespace
packages, but a few other rules are affected as well.
This one has been a bit contentious in the past. It usually uncovers
~700 ecosystem hits. See:
- https://github.com/astral-sh/ruff/pull/16657
- https://github.com/astral-sh/ruff/issues/16690
But I think there's consensus that it's okay to merge as-is. We'd love
an
autofix since it's so common, but we can't reliably tell what a user
meant. The
pattern is ambiguous after all 😆
This is the first rule that actually needed its test case relocated, but
the
docs looked good.
## Summary
This PR Removes deprecated UP038 as per instructed in #18727closes#18727
## Test Plan
I have run tests non of them failing
One Question i have is do we have to document that UP038 is removed?

## Summary
In #11115 we moved from defaulting to $HOME/Library/Application Support
to $XDG_HOME on macOS and added a deprecation warning if we find files
in the old location. So this PR removes the warning
closes#19145
## Test Plan
Ran `cargo test`
Summary
--
Rule and test/snapshot updated, the docs look good
My one hesitation here is that we could hold off stabilizing the rule
until its fix is also ready for stabilization, but this is also the only
preview PTH rule, so I think it's okay to stabilize the rule and later
(probably in the next minor release) stabilize the fixes together.
The tests looked good. For the docs, I added a `## See also` section
pointing to
the closely-related F841 (unused-variable) and the corresponding section
to F841
pointing back to RUF059. It seems like you'd probably want both of these
active
or at least to know about the other when reading the docs.
The constraint representation that we added in #19997 was subtly wrong,
in that it didn't correctly model that type assignability is a _partial_
order — it's possible for two types to be incomparable, with neither a
subtype of the other. That means the negation of a constraint like `T ≤
t` (typevar `T` must be a subtype of `t`) is **_not_** `t < T`, but
rather `t < T ∨ T ≁ t` (using ≁ to mean "not comparable to").
That means we need to update our constraint representation to be an
enum, so that we can track both _range_ constraints (upper/lower bound
on the typevar), and these new _incomparable_ constraints.
Since we need an enum now, that also lets us simplify how we were
modeling range constraints. Before, we let the lower/upper bounds be
either open (<) or closed (≤). Now, range constraints are always closed,
and we add a third kind of constraint for _not equivalent_ (≠). We can
translate an open upper bound `T < t` into `T ≤ t ∧ T ≠ t`.
We already had the logic for doing adding _clauses_ to a _set_ by doing
a pairwise simplification. We copy that over to where we add
_constraints_ to a _clause_. To calculate the intersection or union of
two constraints, the new enum representation makes it easy to break down
all of the possibilities into a small number of cases: intersect range
with range, intersect range with not-equivalent, etc. I've done the math
[here](https://dcreager.net/theory/constraints/) to show that the
simplifications for each of these cases is correct.
## Summary
Resolves#19357
Skip UP008 diagnostic for `builtins.super(P, self)` calls when
`__class__` is not referenced locally, preventing incorrect fixes.
**Note:** I haven't found concrete information about which cases
`__class__` will be loaded into the scope. Let me know if anyone has
references, it would be useful to enhance the implementation. I did a
lot of tests to determine when `__class__` is loaded. Considered
sources:
1. [Python doc
super](https://docs.python.org/3/library/functions.html#super)
2. [Python doc classes](https://docs.python.org/3/tutorial/classes.html)
3. [pep-3135](https://peps.python.org/pep-3135/#specification)
As I understand it, Python will inject at runtime into local scope a
`__class__` variable if it detects references to `super` or `__class__`.
This allows calling `super()` and passing appropriate parameters.
However, the compiler doesn't do the same for `builtins.super`, so we
need to somehow introduce `__class__` into the local scope.
I figured out `__class__` will be in scope with valid value when two
conditions are met:
1. `super` or `__class__` names have been loaded within function scope
4. `__class__` is not overridden.
I think my solution isn't elegant, so I would be appreciate a detailed
review.
## Test Plan
Added 19 test cases, updated snapshots.

- Renames functions to drop `expect_` from names.
- Make functions return `Option<LineColumn>` to appropriately signal
when range is not available.
- Update existing consumers to use `unwrap_or_default()`. Uncertain if
there are better fallback behaviors for individual consumers.
This adds a new `backend: internal | uv` option to the LSP
`FormatOptions` allowing users to perform document and range formatting
operations though uv. The idea here is to prototype a solution for users
to transition to a `uv format` command without encountering version
mismatches (and consequently, formatting differences) between the LSP's
version of `ruff` and uv's version of `ruff`.
The primarily alternative to this would be to use uv to discover the
`ruff` version used to start the LSP in the first place. However, this
would increase the scope of a minimal `uv format` command beyond "run a
formatter", and raise larger questions about how uv should be used to
coordinate toolchain discovery. I think those are good things to
explore, but I'm hesitant to let them block a `uv format`
implementation. Another downside of using uv to discover `ruff`, is that
it needs to be implemented _outside_ the LSP; e.g., we'd need to change
the instructions on how to run the LSP and implement it in each editor
integration, like the VS Code plugin.

Specifically, the [`if_not_else`] lint will sometimes flag
code to change the order of `if` and `else` bodies if this
would allow a `!` to be removed. While perhaps tasteful in
some cases, there are many cases in my experience where this
bows to other competing concerns that impact readability.
(Such as the relative sizes of the `if` and `else` bodies,
or perhaps an ordering that just makes the code flow in a
more natural way.)

## Summary
This is a follow-up to https://github.com/astral-sh/ruff/pull/19321.
Now lazy snapshots are updated to take into account new bindings on
every symbol reassignment.
```python
def outer(x: A | None):
if x is None:
x = A()
reveal_type(x) # revealed: A
def inner() -> None:
# lazy snapshot: {x: A}
reveal_type(x) # revealed: A
inner()
def outer() -> None:
x = None
x = 1
def inner() -> None:
# lazy snapshot: {x: Literal[1]} -> {x: Literal[1, 2]}
reveal_type(x) # revealed: Literal[1, 2]
inner()
x = 2
```
Closesastral-sh/ty#559.
## Test Plan
Some TODOs in `public_types.md` now work properly.

## Summary
Adds support for generic PEP695 type aliases, e.g.,
```python
type A[T] = T
reveal_type(A[int]) # A[int]
```
Resolves https://github.com/astral-sh/ty/issues/677.
## Summary
Support cases like the following, where we need the generic context to
include both `Self` and `T` (not just `T`):
```py
from typing import Self
class C:
def method[T](self: Self, arg: T): ...
C().method(1)
```

## Summary
Pr #11919 changed the fuzz build from `taiki-e/install-action` to
`cargo-bins/cargo-binstall` for necessary reasons of version selection.
But it left the `with:` parameter, which the `binstall` action does not
support. As a result, all workflow runs are showing a warning:
> Unexpected input(s) `'tool'`, valid inputs are `['']`
Eliminate the warning by removing the `with` parameter.
## Test Plan
Run CI, determine that the "cargo fuzz build" step no longer includes an
Annotation showing the warning message (quoted above).
