Attendees: Benoit Hudson (ImgSpc), Mohamed Kouba (ANSYS Inc.), Victor Milovanov, Amos Li, Mark Visser (Unity)
Agenda (Mark) Suggest we use a "needs discussion" label on issues and PRs for next time. Then we can just go through them on the call. Who can tag issues? (Mark) Can we get a status update on joining the .NET Foundation? Github issue: Joining the .NET Foundation <https://github.com/pythonnet/pythonnet/issues/956> - Any response? (Mark) PR review (Mark) Issues review Notes Mark - no news on .NET foundation progress, Mark is investigating internally through Unity if there's some way to get the process moving. Benoit - Amos & Felix still need to connect and chat re: PR#957 Benoit - re: grabbing the GIL in issue#964 - this is by design and should stay that way. Need to document implications of multithreaded environment when Python is embedded in a C# application. GIL needs to be explicitly released and regrabbed via BeginAllowThreads/EndAllowThreads otherwise the process will crash. No change is proposed to this behaviour. Victor - will move PRs that aren't ready for merge to draft state so we have a clearer idea of what's actually in process. Mohamed - in IronPython you can have more than one instance running, i.e. more than one scope. Victor - Python 3.7 or 3.8 has/will/may have sub-interpreters working.. Mark/Benoit - RpyC + subprocesses can achieve the same effect but has marshalling/IPC overhead Mohamed - what's the process for supporting a feature like sub-interpreters in pythonnet Victor - basically propose it at a meeting, get alignment on design, write the code Amos - is there any plan for improving performance? Victor - need performance tests before we check in any PRs around performance, no time at the moment. Hopefully in time for the next meeting or shortly after. Action Items Mark - see if there's a path to the .NET foundation internally and get our application unblocked. Benoit - coordinate discussion between Amos & Felix on #957 Benoit - document how to use pythonnet when you expect to run multithreaded python code (BeginAllowThreads/EndAllowThreads) in an embedded interpreter Victor - move PRs that aren't ready for merging to draft status Mohamed - update #808 according to feedback, time permitting Google doc here: https://docs.google.com/document/d/1rJVU84B_dgx58-_EopjRtOJVFAI2WfHJYV0n7uE1Oak/edit# <https://docs.google.com/document/d/1rJVU84B_dgx58-_EopjRtOJVFAI2WfHJYV0n7uE1Oak/edit#> (please reply or comment in the google doc if I have made any mistakes) Unless otherwise noted, the next working group meeting will be held on Tuesday, October 22 at 3pm EST. Zoom call link: https://unity3d.zoom.us/j/346931511 <https://unity3d.zoom.us/j/346931511> I have all-day meetings that week so I can't attend. Can someone else fill in as moderator for the call?
