All of these files can not be used with pytype at HEAD. They fail during import with various error messages. Make the test script actually load the files and all dependencies of it, instead of just verifying that it can be parsed.
This list was generated by running pytype with more options.
1: typeshed-location was pointed to the current typeshed instead of the one shipped with pytype.
2: --module-name=<foo> was provided as a parameter. Without this parameter wildcard imports "from _ast import *" misbehave.
Files with a "# parse only" comment will only be parsed and not loaded.
It also improves the type checking of contained values. Some methods
were removed because they are implemented by a base class (i.e.,
*__iter__()*, *__str__()*, and *__contains__()*). *__hash__()* was
removed because arrays are unhashable types.
Fixes the following issues:
* Literals rather than ... for default values
* None rather than ... for default value of typed variable
* Literals rather than ... # type for top level constants
* # Foo rather than # type: Foo
* return value of init not set to None
Mypy has issues with running its test suite with many processes
concurrently. This should reduce travis test failures, if not completely
resolve failures. See issue https://github.com/python/mypy/issues/3543
* Add flags to pass on --warn-unused-ignores and --no-implicit-optional to mypy
* Make implicit Optional explicit in arg types (2and3 part)
* Convert {stdlib,third_party}/2 to explicit Optional
* Fix a few return types in stdlib/2/inspect.pyi.
* Rename _FrameRecord to _FrameInfo
* Correct some return types in itertools.pyi from Iterable to Iterator.
* Change types.pyi syntax that pytype can't parse.
* Remove types.pyi from the pytype blacklist.
Starting with python/mypy#2521 mypy is performing stricter function signature
checks.
This makes the stubs diverge from the actual implementation but makes the stubs
internally consistent. Since this is an actual typing issue in the base
implementation, we need to defer to the original authors to fix it.
Sadly, in this case the breakage is rather fundamental and unlikely to get
fixed by upstream. Consider:
```
class AWSAuthConnection(object):
def make_request(self, method, path, headers=None, data='', host=None,
auth_path=None, sender=None, override_num_retries=None,
params=None, retry_handler=None): ...
class AWSQueryConnection(AWSAuthConnection):
def make_request(self, action, params=None, path='/', verb='GET'): ...
```
Hence, until we have a workaround for the error produced by Mypy, we're
excluding those stubs from being tested against.
This simplifies running flake8 tests and reduces the amount of F821 errors
reported (flake8-pyi enables support for forward references in *.pyi files).
The error code is left disabled until I clean up the remaining issues.
Ran both by Travis and locally. There's some setup required, README updated.
A few important Flake8 checks are still disabled, we're going to enable them as
soon as the stubs are fixed and we can reliably run Flake8 locally with Python
3.6.
First was for mypy compatibility, but is no longer needed.
Second is removed by going inheriting (Iterable[bytes],
Container[bytes], Sized, Reversible[bytes]) instead of
Sequence[bytes]. Should presumably catch more errors when using __getattr__
