To support "from six.moves.cPickle import loads", we must add a stub for
six.moves.cPickle as if it were a real submodule, even though it isn't
implemented as such. This fixespython/mypy#1550.
We don't apply this approach to six.moves.builtins on Python 2, because
it seems to confuse mypy.
We also add stubs for aliases in six.moves whose underlying modules have
been added to typeshed.
For Python 2:
- six.moves.SimpleHTTPServer (alias for SimpleHTTPServer)
For Python 3:
- six.moves.tkinter_dialog (alias for tkinter.dialog)
- six.moves.tkinter_filedialog (alias for tkinter.filedialog)
- six.moves.tkinter_commondialog (alias for tkinter.commondialog)
- six.moves.tkinter_tkfiledialog (alias for tkinter.filedialog)
Currently the Python 2 stub for `IntEnum` just inherits from `Enum` without changing anything, meaning that its `value` has type `Any`. This changes it such that, if you know you have an `IntEnum` you get the more specific `int` type for the `value`. Note that this has already been done for Python 3 `IntEnum` (both in `third_party/3/enum.pyi` and `stdlib/3.4/enum.pyi`).
This fixes an error in Travis that seems to have been caused by python/mypy#4319.
The fix was taken from the stdlib/3.4/enum.pyi stub. Mypy no longer assumes
that classes whose metaclass is EnumMeta are subclasses of Enum, so we can't
bound the typevar on Enum.
A call like this:
```
from attr import attrib
from attr.validators import optional, instance_of
c = attrib(default=None, validator=optional(instance_of(bytes)))
```
Was returning no return value, because the first overload was T -> T.
The solution was to change the ordering so that the first overload is
None -> T and infer the type from the other arguments.
Add all cursor types and missing show_warnings method in connections
Added show_warnings to connections. No return type specified as this
requires tracing back through missing return types in previous
author's work. This is out of scope for this pull request.
Added SSDictCursor, SSCursor and DictCursorMixin to complete the
Cursors definition.
* Fix werkzeug environ type
PEP 3333 explicitly calls for environ to be a built-in dict. Using a
Mapping will not only prevent the dict from being modified (which is
explicitly allowed by PEP 3333), it will also cause interaction
problems when the environment is passed to other WSGI handlers.
Also change the value type from object to Any for convenience. By
definition, the values can be anything and can't be type checked.
Using object instead of Any forces us to explicitly cast the value
whenever we access it.
* Use Union[str, unicode] for Werkzeug environment keys
This matches the type in wsgiref.types.
* Use WSGIEnvironment from wsgiref.types
* Add '= ...' to environ attribute
