Closes: #5613
 2022-03-25 10:18:09 +01:00
Alex Waygood b63c963077 Use conditional overloads to simplify several stdlib functions (#7540) 2022-03-25 08:47:03 +01:00
Harry b69d64df60 allow start_server to accept a Sequence of hosts (#7546) 2022-03-24 19:44:45 +01:00
Alex Waygood d086488e0e Revert "Use import instead of type alias in email/message.pyi" (#7548) 
Let's see if this is fixed in mypy 0.942.

This reverts the changes made in #7022, which was a hack to fix #7019

Rebecca Chen f39f20c4dd Fix the type signature of multiprocessing.managers.BaseManager.__exit__ (#7529) 
All parameters should accept None.

Harry eb252afb18 random.sample no longer accepts sets in Python 3.11 (#7528) 
As of 3.11, population must be a Sequence. Automatic conversion of sets to lists is no longer supported.

Harry 71d14b3ee1 random.sample: counts takes Iterable[int] (#7527) 2022-03-21 18:18:24 -07:00
Alex Waygood 74ecce5b68 Improve host parameter of socket.getaddrinfo() (#7518) 
As pointed out by @srittau in #7517, `bytearray` [is redundant](https://docs.python.org/3/library/typing.html#typing.ByteString) in a union where `bytes` is also in the union.

Jelle Zijlstra b7d129f727 PEP 604: Remove some more uses of Union/Optional (#7515) 
The following patterns still break mypy:

1. `type[]` at top level fails
2. `tuple[T1, T2]` at top level fails (but `tuple[T1, ...]` is fine)
3. `T1 | Callable[..., T2 | T3]` fails, but only <=3.9

This PR cleans up usage of `Union` and `Optional` outside these patterns.

Jelle Zijlstra 3e3cc2a6d6 dict.pop: Remove default for second argument (#7481) 
The first overload takes care of the case where there is only one argument, so there should be no default in the second overload.

Jelle Zijlstra 9c50fe7b64 Fix overly precise typing.NewType signature (#7474) 
`type` is incorrect because `NewType` can also accept another `NewType`: https://peps.python.org/pep-0484/#newtype-helper-function

The return type was also wrong; pre-3.10 `NewType()` doesn't return a type object.

Aaron Kau a3e62d56fc change Change IO/IOBase.__exit__ return type to None (#7471) 2022-03-10 15:57:05 +01:00
Aaron Kau bf2049ef18 Change TemporaryFileWrapper.__exit__ return type to None (#7470) 
For context we found this from quora/pyanalyze#496, which makes pyanalyze stricter about context managers that may swallow exceptions. tempfile._TemporaryFileWrapper.__exit__ returns whatever its underlying file returns (https://github.com/python/cpython/blob/3.6/Lib/tempfile.py#L502), and file objects don't tend to return anything from __exit__.

Patrick Rauscher c987c78077 Remove ClassVar from SSLContext.ssl{object,socket}_class (#7465) 
These attributes have class-level defaults, but the docs explicitly state that it's OK to override them on instances.

Akuli f9cb7c3ed4 Use Literal for statistics.quantiles() (#7463) 
I'm going to merge; I think this is consistent with what we've done with e.g. the `byteorder` argument for `int.from_bytes` :)

Alex Waygood db6f912c77 Improve mmap.mmap.__enter__ (#7461) 
It returns `Self` at runtime, not `mmap.mmap`, so inheriting from `AbstractContextManager` doesn't really do anything for us.

Shantanu 9796b9ed69 Improve open overloads when mode is a literal union (#7428) 
As pointed out by @gvanrossum in https://github.com/python/typing/issues/1096

Improves type inference in cases when we know that mode is
OpenBinaryMode, but don't know anything more specific:
```
def my_open(name: str, write: bool):
    mode: Literal['rb', 'wb'] = 'wb' if write else 'rb'
    with open(name, mode) as f:
        reveal_type(f)  # previously typing.IO[Any], now typing.BinaryIO
```

You may be tempted into thinking this is some limitation of type
checkers. mypy does in fact have logic for detecting if we match
multiple overloads and union-ing up the return types of matched
overloads. The problem is the last overload interferes with this logic.
That is, if you remove the fallback overload (prior to this PR), you'd get
"Union[io.BufferedReader, io.BufferedWriter]" in the above example.
