All these attributes can be seen when using `dir(type)`.
In the future we should be discussing if certain methods on object (like
__eq__) should really be there. IMO this should be defined on type where it
actually also appears when using `dir`.
When we import typeshed internally at Dropbox, somehow the fact that
these files are all stubs gets lost (it's a long story...). This
causes errors like this:
.../stdlib/2/ast.pyi:6: error: Name 'typing' already defined (by an import)
The quickest way around this is to rename the import to _typing.
Give it enough information to determine that addinfourl
is iterable and that iteration and read methods return bytes.
Modeled after what is in stdlib/3/urllib/response.pyi after confirming
by looking at Python 2.7 stdlib code.
PR #2516 aimed to widen the accepted file argument to json.dump, but
since `IO` is invariant in its argument, it actually disallowed
passing binary files.
This adds a few stubs that are used by absl-py, and, without them, cause
type checker errors under Pytype:
* TestCase._formatMessage
* TestCase._testMethodName
* TestCase._getAssertEqualityFunc
* TestProgram.runTests
The __new__ method should suffice, and having both interferes with providing
a __new__ in namedtuples, which we want to do to fix
https://github.com/python/mypy/issues/1279.
* Add ExcInfo and OptExcInfo type aliases
* Implement StartResponse using a protocol
* Mark stub-only types with an underscore
* Remove wrong TODO note
python/mypy#1178 is about variable-length tuples, while exc_info()
always returns a tuple with length 3. Ideally, exc_info() would
return Union[Tuple[Type[_E], _E, TracebackType], Tuple[None, None, None]],
but that is a different issue.
It seems that code using HTTPError previously worked by accident
because we used to accept arbitrary keyword arguments when
instantiating BaseException, or any subclass of BaseException
(see https://github.com/python/typeshed/pull/2348).
This commit adds in the correct constructor (which also lets the
user specify the arguments in keyword-argument form).
Note: I'm not very familiar with the urllib libraries, so I opted
to just add the signature and leave it up to somebody else to
fill in the types.
