alberthier / corefoundationasyncio Goto Github PK

Hi!

First let me say a huge thank you for sharing corefoundationasyncio: I had been looking for a way to use asyncio in PyObjC-based Cocoa apps for a while and this is gold. It's working really well for me.

I have an issue with using concurrent.futures.ProcessPoolExecutor, that I use with loop.run_in_executor(). It's mostly working just fine, but in some situations that I haven't quite pinned down yet (but seem repeatable), a sub-process will fail like this: concurrent.futures.process.BrokenProcessPool: A process in the process pool was terminated abruptly while the future was running or pending.

Now, I read your note about the selector implementation, and how it's not compatible with a GUI app. I know concurrent.futures.ProcessPoolExecutor uses the selector module, so I was wondering (without understanding much about the subject in general, I should add) if that may be hinting at the root of my problem. Should I perhaps avoid concurrent.futures.ProcessPoolExecutor and solve my multi-processing needs some other ways, perhaps with the subprocess module?

Thanks for any clues, and thanks again for bringing asyncio to Cocoa!

trying to install corefoundationasyncio on python3.11 with pip22.3 triggers the following warning:

DEPRECATION: corefoundationasyncio is being installed using the legacy 'setup.py install' method, because it does not have a 'pyproject.toml' and the 'wheel' package is not installed. pip 23.1 will enforce this behaviour change. A possible replacement is to enable the '--use-pep517' option. Discussion can be found at pypa/pip#8559

the warning points to the following discussion: pypa/pip#8559
