[jira] [Commented] (PROTON-2286)
Container.selectable(EventInjector) in python on Windows causes "OSError:
[WinError 10038] An operation was attempted on something that is not a
socket", eliminating use of custom events

-----------------------------------------
Not a bug as EventInjector has never worked on windows.

> Key: PROTON-2286
> URL: https://issues.apache.org/jira/browse/PROTON-2286
> Project: Qpid Proton
> Issue Type: Improvement
> Components: python-binding
> Affects Versions: proton-c-0.32.0
> Environment: Windows 10, python 3.7-3.8
> Reporter: alexey
> Priority: Major
>
> First, this hinders examples (db_recv.py and others using EventInjector) from running.
> Second, most important, this doesn't let one have user-defined events in the built-in event loop, which limits its interactivity. Is there another straightforward asynchronous way to send messages on demand?
> Something similar occurred in python asyncio before 3.8, when they made the [{{ProactorEventLoop}}|https://docs.python.org/3/library/asyncio-platforms.html#windows] default on Windows instead of SelectorEventLoop, as select() on windows works only with sockets.
> Also, could someone please integrate proton with python asyncio which is standard convenient way of asynchronous execution in python? Or at least provide an example of using asyncio event loop like with tornado (proton_tornado.py).
> Thank you.
