## Summary
The next sync of typeshed would have failed without manual changes
anyway, so I'm doing one manual sync + the required changes in our
`sys.platform` tests (which are necessary because of my tiny typeshed PR
here: https://github.com/python/typeshed/pull/13378).
closes#15485 (the next run of the pipeline in two weeks should be fine
as the bug has been fixed upstream)
## Summary
Adds two additional tests for `is_equivalent_to` so that we cover all
properties of an [equivalence relation].
## Test Plan
```
while cargo test --release -p red_knot_python_semantic -- --ignored types::property_tests::stable; do :; done
```
[equivalence relation]:
https://en.wikipedia.org/wiki/Equivalence_relation
## Summary
This PR fixes the `show_*_msg` macros to pass all the tokens instead of
just a single token. This allows for using various expressions right in
the macro similar to how it would be in `format_args!`.
## Test Plan
`cargo clippy`
## Summary
This PR creates separate functions to check whether the document path is
excluded for linting or formatting. The main motivation is to avoid the
double `Option` for the call sites and makes passing the correct
settings simpler.
## Summary
This changeset adds new tests for public uses of symbols,
considering all possible declaredness and boundness states.
Note that this is a mere documentation of the current behavior. There is
still an [open ticket] questioning some of these choices (or unintential
behaviors).
## Test plan
Made sure that the respective test fails if I add the questionable case
again in `symbol_by_id`:
```rs
Symbol::Type(inferred_ty, Boundness::Bound) => {
Symbol::Type(inferred_ty, Boundness::Bound)
}
```

## Summary
<!-- What's the purpose of the change? What does it do, and why? -->
Replace typo "security_managr" in AIR303 as "security_manager"
## Test Plan
<!-- How was it tested? -->
a test fixture has been updated
## Summary
Simplification follow-up to #15413.
There's no need to have a dedicated `CallOutcome` variant for every
known function, it's only necessary if the special-cased behavior of the
known function includes emitting extra diagnostics. For `typing.cast`,
there's no such need; we can use the regular `Callable` outcome variant,
and update the return type according to the cast. (This is the same way
we already handle `len`.)
One reason to avoid proliferating unnecessary `CallOutcome` variants is
that currently we have to explicitly add emitting call-binding
diagnostics, for each outcome variant. So we were previously wrongly
silencing any binding diagnostics on calls to `typing.cast`. Fixing this
revealed a separate bug, that we were emitting a bogus error anytime
more than one keyword argument mapped to a `**kwargs` parameter. So this
PR also adds test and fix for that bug.
## Test Plan
Existing `cast` tests pass unchanged, added new test for `**kwargs` bug.
## Summary
I noticed this while trying out
https://github.com/astral-sh/ruff-vscode/issues/665 that we use the
`Display` implementation to show the error which hides the context. This
PR changes it to use the `Debug` implementation and adds the message as
a context.
## Test Plan
**Before:**
```

```
**After:**

## Summary
In `SymbolState` merging, use `BitSet::union` instead of inserting
declarations one by one. This used to be the case but was changed in
https://github.com/astral-sh/ruff/pull/15019 because we had to iterate
over declarations anyway.
This is an alternative to https://github.com/astral-sh/ruff/pull/15419
by @MichaReiser. It's similar in performance, but a bit more
declarative and less imperative.
## Summary
Follow-up PR from https://github.com/astral-sh/ruff/pull/15415🥲
The exact same property test already exists:
`intersection_assignable_to_both` and
`all_type_pairs_can_be_assigned_from_their_intersection`
## Test Plan
`cargo test -p red_knot_python_semantic -- --ignored
types::property_tests::flaky`
## Summary
Implements upstream diagnostics `PT029`, `PT030`, `PT031` that function
as pytest.warns corollaries of `PT010`, `PT011`, `PT012` respectively.
Most of the implementation and documentation is designed to mirror those
existing diagnostics.
Closes#14239
## Test Plan
Tests for `PT029`, `PT030`, `PT031` largely copied from `PT010`,
`PT011`, `PT012` respectively.
`cargo nextest run`

A small PR to reduce some of the code duplication between the various
branches, make it a little more readable and move the API closer to what
we already have for `KnownClass`
## Summary
The cause of this bug is from
https://github.com/astral-sh/ruff/pull/12575 which was itself a bug fix
but the fix wasn't completely correct.
fixes: #14768
fixes: https://github.com/astral-sh/ruff-vscode/issues/644
## Test Plan
Consider the following three cells:
1.
```python
class Foo:
def __init__(self):
self.x = 1
def __str__(self):
return f"Foo({self.x})"
```
2.
```python
def hello():
print("hello world")
```
3.
```python
y = 1
```
The test case is moving cell 2 to the top i.e., cell 2 goes to position
1 and cell 1 goes to position 2.
Before this fix, it can be seen that the cells were pushed at the end of
the vector:
```

NotebookCell {
document: TextDocument {

},
NotebookCell {

},
},
NotebookCell {
document: TextDocument {
contents: "def hello():\n print(\"hello world\")",
},
},
]
```
After the fix in this PR, it can be seen that the cells are being pushed
at the correct `start` index:
```

## Summary
[**Rendered version of the new test
suite**](https://github.com/astral-sh/ruff/blob/david/intersection-type-tests/crates/red_knot_python_semantic/resources/mdtest/intersection_types.md)
Moves most of our existing intersection-types tests to a dedicated
Markdown test suite, extends the test coverage, unifies the notation for
these tests, groups tests into a proper structure, and adds some
explanations for various simplification strategies.
This changeset also:
- Adds a new simplification where `~Never` is removed from
intersections.
- Adds a new simplification where adding `~object` simplifies the whole
intersection to `Never`
- Avoids unnecessary assignment-checks between inferred and declared
type. This was added to this changeset to avoid many false positive
errors in this test suite.
Resolves the task described in this old comment
[here](e01da82a5a..e7e432bca2 (r1819924085)).

Prompted by
> One nit: I think we need to consider `Any` and `Unknown` and `Todo` as
all (gradually) equivalent to each other, and thus `type & Any` and
`type & Unknown` and `type & Todo` as also equivalent. The distinction
between `Any` vs `Unknown` vs `Todo` is entirely about
provenance/debugging, there is no type level distinction. (And I've been
wondering if the `Any` vs `Unknown` distinction is really worth it.)
The thought here is that _most_ places want to treat `Any`, `Unknown`,
and `Todo` identically. So this PR simplifies things by having a single
`Type::Any` variant, and moves the provenance part into a new `AnyType`
type. If you need to treat e.g. `Todo` differently, you still can by
pattern-matching into the `AnyType`. But if you don't, you can just use
`Type::Any(_)`.
(This would also allow us to (more easily) distinguish "unknown via an
unannotated value" from "unknown because of a typing error" should we
want to do that in the future)

## Summary
This moves almost all of our existing `UnionBuilder` tests to a
Markdown-based test suite.
I see how this could be a more controversial change, since these tests
where written specifically for `UnionBuilder`, and by creating the union
types using Python type expressions, we add an additional layer on top
(parsing and inference of these expressions) that moves these tests away
from clean unit tests more in the direction of integration tests. Also,
there are probably a few implementation details of `UnionBuilder` hidden
in the test assertions (e.g. order of union elements after
simplifications).
That said, I think we would like to see all those properties that are
being tested here from *any* implementation of union types. And the
Markdown tests come with the usual advantages:
- More consice
- Better readability
- No re-compiliation when working on tests
- Easier to add additional explanations and structure to the test suite
This changeset adds a few additional tests, but keeps the logic of the
existing tests except for a few minor modifications for consistency.
