Attendees: Benedikt, Victor, Amos, Mohamed, Mark Agenda

• Review action items from last meeting:
• Benedikt - continue working on joining .NET foundation 
• Benoit - multithreaded python code
• ? - breaking up Quantconnect PR 
• ? - github actions
• Amos - continue breaking up pull 958 into smaller PRs to make it easier to review and merge.  e.g. have a single PR that gets reference counts right and doesn't touch GC chains. See Benoit's example of the __import__ restore PR for best practices.
• Amos - same for other older PRs
• Benedikt - will try to reproduce PyBuffer crash locally
• Benedikt - will check if there are any breaking changes since 2.4.0
• Benedikt - continue exploring CLR loader, splitting parts into separate Python interop DLLs, have main Python runtime implement layers on top
• Victor - Perf runs in CI
• Review PRs
• Mailing list
• currently moderated - @markv asked for ownership to be transferred to Benedikt

• joining .NET
• process had changed, Benedikt working on it
• Pull 958 (domain reload handling)
• split PRs being approved and merged, thanks Amos!
• github actions
• if we join .NET we can stay on current setup
• would be nice to have Darwin CI working
• PyBuffer
• nothing done yet
• CLR loader
• modernization PR has a single build
• Python 2 should still work, but Benedikt won't spend a lot of time on Python 2, 3.5+ is current focus
• moved code and tests into separate directories
• removed old csproj file in favour of small project files generated using .NET CLI
• goal is a fully building project using .NET CLI that is operating system independent
• made a small pythonnet module that will be the future entry point
• still rough, testing currently with core CLR and Mono on Linux
• loading works, P/Invoke __internal breaks on .NET core
• Python functions have been split out into an interface
• using T4 templates
• ready for early review if you can take a look
• Performance tests and CI
• not very stable if we put in CI, fail depending on weather conditions
• no way to put in CI without random failures
• maybe makes sense to keep it as an ongoing statistic on master and not blocking PRs
• useful for running locally on branch vs. master to check for regressions
• still informative for detecting regressions - we can run it on every PR, but it shouldn't result in a hard error - can we report it on the PR?
• perf comparison is relative, so different machines shouldn't affect the result
• Mailing list
• keep it, but remove moderation, transfer ownership to Benedikt
• Improve method binding PR #974 discussion
• Meeting on January 2 is cancelled, next meeting will be in 4 weeks on Thursday, January 16, 2020

• Benedikt will continue working on .NET foundation application
• Victor will take a look at the CLR loader PR, looks big though
• Victor will look into if we can generate perf stats through AppVeyor and Travis
• Victor will publish a PR for conversion config
• Mohamed will split PR #974
• Benoit - multithreaded python code
• ? - breaking up Quantconnect PR 
• Benedikt - will try to reproduce PyBuffer crash locally
