e0f9242e76 io: StringIO seems happy enough to take None (#3973) 
Didn't check C code, but the _pyio implementation explicitly checks for
None

90aa27b54a Fix the signature of IOBase._checkClosed(). (#3305) 
* In Python 2, the optional `msg` argument was missing.
* In Python 3, the method was missing altogether.

b294782183 Make most contextmanager __exit__ signatures return Optional[bool] (#3179) 
This pull request is a follow-up to https://github.com/python/mypy/issues/7214.

In short, within that mypy issue, we found it would be helpful to
determine between contextmanagers that can "swallow" exceptions vs ones
that can't. This helps prevent some false positive when using flags that
analyze control flow such as `--warn-unreachable`. To do this,
Jelle proposed assuming that only contextmanagers where the `__exit__`
returns `bool` are assumed to swallow exceptions.

This unfortunately required the following typeshed changes:

1. The typing.IO, threading.Lock, and concurrent.futures.Executor
   were all modified so `__exit__` returns `Optional[None]` instead
   of None -- along with all of their subclasses.

   I believe these three types are meant to be subclassed, so I felt
   picking the more general type was correct.

2. There were also a few concrete types (e.g. see socketserver,
   subprocess, ftplib...) that I modified to return `None` -- I checked
   the source code, and these all seem to return None (and don't appear
   to be meant to be subclassable).

3. contextlib.suppress was changed to return bool. I also double-checked
   the unittest modules and modified a subset of those contextmanagers,
   leaving ones like `_AssertRaisesContext` alone.

701f970c6f Add overrides for the methods 'readlines' and 'writelines' in TextIOBase. (#2551) 
Without the overrides, MRO will pick the methods in IOBase which have
the wrong signatures.

00cda79cf5 add io.TextIOWrapper.read in 3.3 (#2248) 
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.

6d7173b70b Add StringIO.name and BytesIO.name (#1802) 
Also, change the type of StringIO.name (Python 3) from str to Any.

Neither StringIO nor BytesIO actually define a name field, but the
super-class IO[T] of both in typeshed does define a read-only property.
This means that sub-classes of StringIO and BytesIO adding this field
will not typecheck correctly.

Closes: #1790

f6b60cb3ea A couple fixes to the io stubs. (#1811) 
1. The 'name' argument to FileIO.init can be either a string or an integer: https://docs.python.org/2/library/io.html#io.FileIO
2. An mmap.mmap object can be used in most places that a bytearray can: https://docs.python.org/3.5/library/mmap.html
