From previous meeting(s)

  • (IF) Python 3.10

    • conda issue - https://github.com/conda/conda/issues/10969
    • How to allow older conda users to fail?
      1. Let them find out
      2. Add a __conda virtual package and let
        python=3.10 package depend on __conda>=4.10.3
      3. symbolic link lib/python3.1 -> lib/python3.10
    • TODO New python build that does the symlink (option #3 above)
    • Py3.10-related fixes will be rolled into next conda minor release

  • (CJ via MRB) more reproducible builds?

    • CJ: thinks its pretty close
    • motivated by this blog post: https://hpc.guix.info/blog/2021/09/whats-in-a-package/
    • embed azure build log into the package
    • embed which build system
    • git hash of feedstock?
    • turn off force push to feedstocks
    • need a way to force the build/host/test envs to be the same
    • (IF): see https://github.com/conda/conda-build/issues/2140
    • Possible TODOs
      • store source for builds somewhere
      • store logs for builds somewhere, possibly keyed on package name?
        • And parts of the info.json – sometimes we have the same filename for different builds
      • store conda-locks of the build/host/test environments
    • Notes
      • transparency vs repeatability vs reproducibility
      • Provenance != reproducibility
      • (Eric) transparency+repeatability > reproducibility

    • We have $3000 credits from Oracle for a year
      • Enough for 8 runners with 4 vCPUs and 24 GB for a
        year
    • options
      1. host our own drone server/runners
      2. host our own azure agents
      3. cross compile
