## Summary
Fixes https://github.com/astral-sh/ty/issues/2292
When solving a bounded typevar, we preferred the upper bound over the
actual type seen in the call. This change fixes that.
## Test Plan
Added mdtest, existing tests pass.
## Summary
This raises a `ValueError` at runtime:
```python
from functools import total_ordering
@total_ordering
class NoOrdering:
def __eq__(self, other: object) -> bool:
return True
```
Specifically:
```
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/Library/Frameworks/Python.framework/Versions/3.11/lib/python3.11/functools.py", line 193, in total_ordering
raise ValueError('must define at least one ordering operation: < > <= >=')
ValueError: must define at least one ordering operation: < > <= >=
```
See: https://github.com/astral-sh/ty/issues/1202.
Snapshot tests recently started reporting this warning:
> Snapshot test passes but the existing value is in a legacy format.
> Please run cargo insta test --force-update-snapshots to update to a
> newer format.
This PR is the result of that forced update.
One file (crates/ruff_db/src/diagnostic/render/full.rs) seems to get
corrupted, because it contains strings with unprintable characters that
trigger some bug in cargo-insta. I've manually reverted that file, and
also manually reverted the `input_file:` lines, which we like.
## Summary
Decorators are now called with the class as an argument, and the return
type becomes the class's type. This mirrors how function decorators
already work.
Closes https://github.com/astral-sh/ty/issues/2313.
## Summary
As-is, the following rejects `return self.value` in `def other` in the
subclass
([link](https://play.ty.dev/f55b47b2-313e-45d1-ba45-fde410bed32e))
because `self.value` is resolving to `Unknown | int | float | property`:
```python
class Base:
_value: float = 0.0
@property
def value(self) -> float:
return self._value
@value.setter
def value(self, v: float) -> None:
self._value = v
@property
def other(self) -> float:
return self.value
@other.setter
def other(self, v: float) -> None:
self.value = v
class Derived(Base):
@property
def other(self) -> float:
return self.value
@other.setter
def other(self, v: float) -> None:
reveal_type(self.value) # revealed: int | float
self.value = v
```
I believe the root cause is that we're not excluding properties when
searching for class methods, so we're treating the `other` setter as a
classmethod. I don't fully understand how that ends up materializing as
`| property` on the union though.
## Summary
If we match on an `TestEnum | None`, then when adding a case like
`~Literal[TestEnum.FOO]` (i.e., after `if value == TestEnum.FOO:
return`), we'd distribute `Literal[TestEnum.BAR]` on the entire builder,
creating `None & Literal[TestEnum.BAR]` which simplified to `Never`.
Instead, we should only expand to the remaining members for pieces of
the intersection that contain the enum.
Now, `(TestEnum | None) & ~Literal[TestEnum.FOO] &
~Literal[TestEnum.BAR]` correctly simplifies to `None` instead of
`Never`.
