add_argument's type argument was recently changed to be (approximately)
`Callable[[_Text], _T]`. Because of contravariant subtyping for functions,
this had the effect of requiring that add_argument *always*
be unicode, which is wrong.
Change it to be `Callable[[str], _T]`.
* Add _AttributeHolder and _ActionsContainer classes to argparse.
* Add Action subclasses to argparse.
* Add _UNRECOGNIZED_ARGS_ATTR, _ensure_value, _get_action_name to argparse.
* Fill in remaining _ActionsContainer attributes.
* Fill in missing argparse.ArgumentParser attributes.
* Fill in missing argparse.HelpFormatter attributes.
* Fill in remaining missing attributes on argparse classes.
* Rename TypeVar _ActionVar to _ActionT
* Add a version check for FileType attributes
* Add '# undocumented' where appropriate
* Add more # undocumented comments
* Make arguments to _ActionsContainer.add_argument more precise.
As promised in #2014.
There are virtually no real changes between Python 2 and 3 in this module, but the stub had accumulated some meaningless differences. I also fixed a few incorrect types.
They have getaddrinfo(3) as their backend, and accept port='http' etc. You can even omit (pass None to) either of host or port for start_server() to effectively select 'localhost' and an arbitrary ephemeral port, respectively.
* Make {C,WIN,PY}FUNCTYPE's restype argument optional (for void returns)
* Make WinError return WindowsError
* Don't have Array explicitly inherit from Sized
(since inheriting from classes with different metaclasses causes problems,
and it is a protocol anyways)
* Have Array.__iter__ properly return an Iterator instead of an Iterable
* Support additional argument types for c_void_p parameters
* Don't allow passing bytes where a writable c_void_p is expected
* Fix type of ctypes._CDataMeta.__[r]mul__
* Rename ctypes._cparam to _CArgObject to match the real type name
* Fix value type of ctypes.HRESULT
* Add stub for ctypes.wintypes
* Fix trailing whitespace in ctypes.wintypes
* Add a workaround to ctypes.Array to fix incorrect typing in some cases
* Expand multiple assignments so mypy recognizes them as type aliases
* Rename ctypes._Pointer to pointer so it can be used externally
This is in our style guide. This is the last piece of offending code; I just submitted ambv/flake8-pyi#10 to enforce the rule in the linter in the future.
* ArgumentParser's add_argument returns the Action that was created.
* Make add_argument's dest parameter Optional. _ArgumentGroup's add_argument should also return the Action.
- Made deque.maxlen read-only
- We don't support 3.2, so we don't care about signature changes in it
- There don't seem to be any missing set operations (I compared the dir() of this class to that of builtins.set)
In python3 `RotatingFileHandler` is a subclass of `BaseRotatingHandler` which is a subclass of `FileHandler` which is a subclass of `StreamHandler` which as a `terminator` property but I'm getting a `"RotatingFileHandler" has no attribute "terminator"` error on my code.
The generic type of the futures provided to the wait method cannot
currently be preserved through this definition. For now deleting the
unused NamedTuple is the best approach.
