[issue17805] No such class: multiprocessing.pool.AsyncResult

[Volker Weißmann]

Volker Weißmann  added the comment:

The documentation here: 
https://docs.python.org/3/library/multiprocessing.html#module-multiprocessing.pool
says that apply_async is "A variant of the apply() method which returns a 
result object."
You should replace "a result object" with "a AsyncResult/ApplyResult object" 
and a link to 
https://docs.python.org/2/library/multiprocessing.html#multiprocessing.pool.AsyncResult

Richard Oudkerk added the comment:

It might be simplest to make the implementation match the docs by making 
AsyncResult an alias for ApplyResult.

[issue17805] No such class: multiprocessing.pool.AsyncResult

[Takafumi Arakaki]

New submission from Takafumi Arakaki:

Document mentions AsyncResult but there is no such class.
http://docs.python.org/2/library/multiprocessing.html#multiprocessing.pool.AsyncResult

You can check it by simply running:
python -c 'from multiprocessing.pool import AsyncResult'

I think it means ApplyResult so I made a patch (attached).

Note that there managers.py also uses name 'AsyncResult':
% hg grep AsyncResult
Doc/library/multiprocessing.rst:83232:.. class:: AsyncResult
Lib/multiprocessing/managers.py:81039:'apply_async': 'AsyncResult',
Lib/multiprocessing/managers.py:81039:'map_async': 'AsyncResult',
Lib/multiprocessing/managers.py:81039:'starmap_async': 'AsyncResult',
Lib/multiprocessing/managers.py:81039:SyncManager.register('AsyncResult', 
create_method=False)

Probably renaming them would be better?
