* Add os.add_dll_directory()
* Add memfd_create() and flags
* Add type annotation to flags
* Add stat_result.st_reparse_tag and flags
* Add ncurses_version
* Add Path.link_to()
* Add Picker.reducer_override()
* Add plistlib.UID
* Add has_dualstack_ipv6() and create_server()
* Add shlex.join()
* Add SSL methods and fields
* Add Python 3.8 statistics functions and classes
* Remove obsolete sys.subversion
* Add sys.unraisablehook
* Add threading.excepthook
* Add get_native_id() and Thread.native_id
* Add Python 3.8 tkinter methods
* Add CLOCK_UPTIME_RAW
* Add SupportsIndex
* Add typing.get_origin() and get_args()
* Add unicodedata.is_normalized
* Add unittest.mock.AsyncMock
Currently this is just an alias for Any like Mock and MagicMock. All of
these classes should probably be sub-classing Any and add their own
methods. See also #3224.
* Add unittest cleanup methods
* Add IsolatedAsyncioTestCase
* Add ElementTree.canonicalize() and C14NWriterTarget
* cProfile.Profile can be used as a context manager
* Add asyncio task name handling
* mmap.flush() now always returns None
* Add posonlyargcount to CodeType
Nothing prevents a decorator defined using `@decorator` from
changing the signature of the decorated function. For example,
this example changes the return type to `str`:
```
from decorator import decorator
@decorator
def stringify(f, *args, **kwargs) -> str:
return str(f(*args, **kwargs))
```
The old signature caused false positives in internal Dropbox code.
I couldn't come up with a signature that would produce better types
with mypy while not generating false positives.
* Remove custom _Text type
Since the custom type was only used in argument types, it was
effectively only an alias for typing.Text.
* Run requests/api.pyi through black
* Update how mock classes alias to Any
> First, the z: Any situation looks like a bug or accidental feature to me.
This is definitely meant (and works) as a variable declaration; that it
also allows using z as a type seems wrong. I can't find any evidence in
PEP 484 that this was intended; in mypy it's likely the accidental result
of other design choices meant to shut up errors about Any.
Ideally these classes could be declared as empty class stubs, but since the comments suggest this isn't possible yet, let's update these to be type aliases to Any rather than global variables of type Any. This would avoid invalid type errors when the implementation of type checkers respect the intention that `z: Any` does not make `z` a valid type.
* Update mock.pyi
* Fix flask render_template and render_template_string stubs
* Add types for flask view function
* Import TracebackType from the right location
* Switch to bound typevar in route decorator stub
* Change render_template and render_template_string parameters to Text
