[skip issue]Small changes in importing process of multiprocessing package by bombs-kim · Pull Request #6856 · python/cpython

bombs-kim · 2018-05-15T10:08:34Z

It seems that the way multiprocessing package set __all__ is overly complex. And __all__ in context.py is not used in __init__.py so I guess the comment there is misleading.

…in __init__.py

@1st1 I've submitted PSF form. Maybe some errors has happened. Could you please check this out and remove CLA not sign tag?

Added Davin as a reviewer as multiprocessing is his territory.

Please add tests for __all__. The test.support.check__all__ helper can be used for this.

bombs-kim · 2018-05-24T00:01:07Z

@serhiy-storchaka Thank you so much. I will upload that as early as I can, but it can take some time because I'm new to test

serhiy-storchaka · 2018-05-24T04:56:47Z

Just look how this helper is used in other tests.

bombs-kim · 2018-06-01T02:09:01Z

@serhiy-storchaka Sorry for being late. I've added a test case but I'm not sure this is what you intended. Public objects in multiprocessing package are bound methods of multiprocessing.context._default_context object and they don't have __module__ attributes and they are not types.ModuleType, either. So I think using check__all__ is pretty pointless here because you cannot make expected automatically in that function.

@applio I know it's a trivial contribution, but I want to know the progress of PR.

-globals().update((name, getattr(context._default_context, name))
- for name in context._default_context.__all__)
-__all__ = context._default_context.__all__
+__all__ = [x for x in dir(context._default_context) if not x[0].startswith('_')]


Shouldn't x[0].startswith('_') be x.startswith('_')?

Yes, you are right. Thank you🙂

 from . import reduction

-__all__ = [] # things are copied from here to __init__.py
+__all__ = []


Could we use __all__ = ()? Or __all__ is modified later?

I don't think it's modified. I will run the test and tell you the result

@methane I updated things that you pointed out. It passed all tests. Thanks.
