These type annotations are unnecessary and seem to confuse the type system.
* Remove annotation from PlistFormat enum members
Same rationale as python/typeshed#2314; same adverse effects observed.
Also, mark AST._attributes and _fields as class vars.
`lineno` and `col_offset` were previously defined on a few sub-classes of `AST`, e.g. `expr`, even though https://docs.python.org/3/library/ast.html explicitly states that `AST` has these two attributes. These attributes are only present if they were supplied as arguments to the constructor, but the same is true for the subclasses.
* Drop support for Python 3.3
* Merge Python 2 and 3 shutil
* Marked some arguments optional
* Changed callback return type from None to Any for more flexibility
The previous definitions in `mock` caused many false positives in
internal Dropbox repositories.
One source of problems was `List[Mock]` not being compatible with
`List[SomeClass]`, since `list` is invariant.
This is needed to make TextIOWrapper and a few classes that inherit
from it concrete in 3.3. I am actually not sure whether this method
exists at runtime; there's nothing in
https://docs.python.org/3/library/io.html#io.TextIOWrapper
that suggests it was added in 3.4. In any case, it hardly matters
since 3.3 usage should be very rare now.
Make the Python 2 and 3 concurrent.futures stubs identical so fixes get
applied to both.
For example, #1305 and #2233 fixed the same problem at different times,
as did #1078 and #1911.
By making the stubs identical, we apply the fix from #1711 to Python 2.
Fixes#2234.
memoryview type information inconsistent with documentation of typing module.
`memoryview` should be a ByteString like the docs say.
`memoryview.__init__` does not accept str, and instead of a union it should just accept ByteString.
`memoryview.__iter__` returns an Iterator[int] not bytes.
Fixes#1850.
The fix was already applied to Python 2, but the typevar-based solution there
leads to "cannot infer value of type variable" in mypy. I used the following
script to check:
```python
from itertools import product
reveal_type(product([1]))
reveal_type(product([1], ['x'], [False], [3.0], [(1,)], [('x',)], [{1}], [{1: 2}], repeat=5))
```
Fixes#1940.
This makes it so that mypy will infer the common base class of these
classes to be Awaitable instead of Iterable. I verified that this
fixes the errors in the script posted by @neilconway.
The annotations, formatarg, formatvarargs, formatvarkw, formatvalue,
formatreturns, and formatannotations arguments to inspect.formatargspec
have default values, but they cannot be None.
This module is going to be used by mypy for the daemon on Windows. To that end I ran stubgen on _winapi, then read through Modules/_winapi.c to add the function types. This seems to have been added in Python 3.1, but I think it is completely fine to just leave it in stdlib/3.
* add inspect.{isasyncgenfunction,isasyncgen} (3.6)
* reorder inspect.CO_* as in Python 3.6 doc
* add inspect.CO_{COROUTINE,ITERABLE_COROUTINE} (3.5)
* add inspect.CO_ASYNC_GENERATOR (3.6)
* use variable annotations
* use version checks
* Parameter.empty is a class attribute
* Signature.empty is a class attribute
