The whole asyncio.ProactorEventLoop stuff is not really explained anywhere. Maybe a "How to use asyncio on Windows" could be useful.
It is explained in the subprocess methods of the event loop. Well, I expected this reaction: the subprocess documentation is currently splitted in two parts (event loop and asyncio.subprocess). IMO all functions related to subprocess must be moved to the subprocess page. Here is a patch to group all subprocess documentation. I added a "Connect pipes" section, mentionned that event loop functions are the "low level API" whereas the asyncio.subprocess is the "high level API". ---------- Added file: http://bugs.python.org/file34545/asyncio_subprocess.patch _______________________________________ Python tracker <report@bugs.python.org> <http://bugs.python.org/issue21006> _______________________________________
