* add typing.ContextManager for 3.6+ only
This fixes the easier part of #655.
Would it make sense to add a generic typing.ContextManager that exists in any Python version?
* update comment
* fix argument types for ContextManager.__exit__
* add AsyncContextManager
* add @asynccontextmanager
* typing.ContextManager now always exists
* back out async-related changes
Will submit those in a separate PR later
* fix import order
* AbstractContextManager only exists in 3.6+
* AbstractContextManager -> ContextManager
* Update pbkdf2_hmac for Python 3.5
- Use `iterations` instead of `rounds` if running on 3.5
- Change `dklen` to `Optional`
* Use `iterations` instead of `rounds` in 3.4+
* Add missing methods to Python 2 concurrent.futures
Future.exception_info() and Future.set_exception_info() are methods
present only in the Python 2 backport of concurrent.futures.
* Mark timeout args as optional
* Updated the typehints for itertools.
* Removed the overload because it caused problems and cleaned up the imports.
* Update itertools.pyi
Added back optionality of second argument for itertools.permutations.
* Update itertools.pyi
Moved the Optional which I accidentially put on the wrong function -.-
The previous change was still right. Unique among `poplib` functions, `uidl()` returns a long response when called without arguments, but just a bytes string when called with a `which` argument.
Put this in stdlib/3 because it changed pretty radically in 3.2. We might be
able to move it to 2and3 later, but I want to focus on completing the Python 3
standard library first.
* Fix incorrect usage of AnyStr
- sqlite3 was using Union[bytes, AnyStr], which doesn't make sense
- The urllib functions I changed accept either bytes or str for their "safe"
argument
- Also added supports for PathLike to pstats
- Remove some unused imports of AnyStr
* pstats: python 2 accepts unicode
* improve stubs for _codecs
I noticed that many of these used AnyStr in a context where it doesn't make
sense. Found a few more things after reviewing _codecsmodule.c:
- Some Windows-only functions were omitted
- A few argument counts and names and return types were wrong
The Python 2 _codecs stub has many of the same issues, but the module is also
pretty similar between Python 2 and 3. I'm planning to send another PR after this
one to merge the two and move the stub into 2and3.
* correct platform name
Fixespython/mypy#3247
Also reviewed some related logic:
- __mod__ was added to both bytes and bytearray with PEP 461, which went into 3.5
- str.__mod__ takes only one argument, and the signature calls it "value"
- In Python 2, bytearray doesn't have __mod__ (and typeshed correctly omits it)
* Add pyi for pydoc [Python 2.7]
* Fixed issues
* A few more fixes
- `synopsis -> Optional[AnyStr]`
- `visiblename` takes a `Container`
- `getdoc -> Union...` not `AnyStr`
* `synopsis` and `source_synopsis`
This is the other half of fixing #1115.
Also fixed the stub for JSONDecodeError and made it only exist in 3.5+.
Didn't otherwise review the exact attributes and types in the package.
* Change Uses of List[] to Sequence[] in argument positions.
One of these (parse_args()) broke in real-world code, because the
expected type was List[Union[str, bytes]] but the actual type was
List[str] (because List is invariant). That is ridiculous, so I
changed the accepted type to Sequence[_Text] which is covariant. Then
I found a few other methods/functions that probably should also be
changed to Sequence, but I'm less certain of those. I'm not at all
sure about the instance/class attributes, so I left those alone
(though I suspect those might also have to switch).
* Fixes suggested by code review
- Changed Sequence[Option] to Iterable[Option] everywhere
- Changed _process_args to plain List
