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
* fix type for TestCase.assertIn
This does essentially `assert member in container`, so we want a `Container`, not an `Iterable`.
This came up in 68e9d426a8..0bbee43d60 (r192525658).
* use any for assertIn
The type signature of get_grouped_opcodes() was incorrect. Resulting in type errors when checking return values.
The usage of this function is like this:
groups = sm.get_grouped_opcodes() # groups is Iterable[List[Tuple[str, int, int, int, int]]]
for group in groups: # group is List[Tuple[str, int, int, int, int]]
for opcode in group: # opcode is Tuple[str, int, int, int, int]
The dict stub was referring to an instance, not the type, leading to
__call__ being considered when using as a decorator, rather than
__init__.
mock is a backport of the stdlib module and should be defined the same.
* Add OpenDirector.addheaders and replace type comments with annotations
* Use ClassVar/eliminate `= ...` and add BaseHandler.handler_order (exists in Py2 versions)
* Use typing.Text
* Add InputStream and ErrorStream WSGI protocols
* Fix return type of WSGIApplication
* Add type hints to wsgiref.validate
* Replace _Bytes by plain bytes
* Add wsgiref.util
* Add wsgiref.headers
* ErrorWrapper.writelines() takes an Iterable
* Fix start_response return type
* Make Python 2 and 3 branches resemble each other more closely
* Use typing.NoReturn
* Fix WriteWrapper.writer type
* Change return type of WriteWrapper.writer to Any
