* Change (Py3) email message payload type
The docstring of the Message get_payload method indicates that the
possible return types include None and bytes. Additionally the
set_payload method accepts bytes. Therefore I've changed the
PayloadType to include bytes and the get_payload return type to be an
Optional PayloadType.
* Change email (Py3) message_from_file IO types
Instead of using TextIO and BinaryIO use IO[str] and IO[bytes]
respectively to match the type returned by the open builtin. This
follows the recommendations in #283.
The error that prompts this is reproduced via:
```
from email import message_from_file
with open('email') as file_:
email = message_from_file(file_)
```
Argument 1 to "message_from_file" has incompatible type IO[Any]; expected "TextIO"
timegm takes struct_time objects, which are NamedTuples that have 9 elements by default
That would not take Tuple[Int], so typeshed would report errors
This reverts commit d43adbe97e.
Here's a simple example of code that breaks with this PR:
from typing import Mapping, Dict, Tuple
a = {('0', '0'): 42} # type: Mapping[Tuple[str, str], int]
b = a.get(('1', '1'), 0)
This gives an error on the last line:
error: No overload variant of "get" of "dict" matches argument types [Tuple[builtins.str, builtins.str], builtins.int]
* Add empty stubs for gettext Translations subclasses
GNUTranslations and NullTranslations do not add any methods to the base
Translations class, so remove the TODO comment and just declare the
classes.
* Add missing types for py3 gettext.
* Almost all re functions take a compiled pattern. (Even re.compile()!)
Fixes#188
Note: I'm using AnyStr so that the type of string used for pattern and
for the rest of the arguments must match. This is not 100% correct,
since Python 2 sometimes allows mixed types. But sometimes it
doesn't, depending on the values (e.g. non-ASCII bytes), and Python 3
always insists on matching, so I think this is actually a good idea.
* Same treatment for stdlib/3/re.pyi.
* subprocess.CalledProcessError output argument is optional.
* subprocess.CalledProcessError takes stderr argument in python3.
* subprocess: Fix type for command in call() and friends.
The stubs didn't correctly support the fact that you can pass a string
as well as a sequence of strings.
