[issue17805] No such class: multiprocessing.pool.AsyncResult
New submission from Takafumi Arakaki: Document mentions AsyncResult but there is no such class. http://docs.python.org/2/library/multiprocessing.html#multiprocessing.pool.A... 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? ---------- assignee: docs@python components: Documentation files: ApplyResult.patch keywords: patch messages: 187466 nosy: docs@python, tkf priority: normal severity: normal status: open title: No such class: multiprocessing.pool.AsyncResult versions: Python 2.6, Python 2.7, Python 3.1, Python 3.2, Python 3.3, Python 3.4, Python 3.5 Added file: http://bugs.python.org/file29954/ApplyResult.patch _______________________________________ Python tracker <report@bugs.python.org> <http://bugs.python.org/issue17805> _______________________________________

Richard Oudkerk added the comment: It might be simplest to make the implementation match the docs by making AsyncResult an alias for ApplyResult. ---------- _______________________________________ Python tracker <report@bugs.python.org> <http://bugs.python.org/issue17805> _______________________________________

Volker Weißmann <volker.weissmann@gmx.de> added the comment: The documentation here: https://docs.python.org/3/library/multiprocessing.html#module-multiprocessin... 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.... ---------- nosy: +Volker Weißmann versions: +Python 3.10, Python 3.5, Python 3.6, Python 3.7, Python 3.8, Python 3.9 -Python 2.7, Python 3.3, Python 3.4 _______________________________________ Python tracker <report@bugs.python.org> <https://bugs.python.org/issue17805> _______________________________________
