Your new() agenda items

• DG: conda build tools meetings are coming back up: next one Oct 10th. Check with Bianca. See conda community events calendar: https://conda.org/community/calendar
• WV: rattler-build rollout is going on and seems to progress nicely. Outstanding items
  • Version bumping not available yet
  • Migrator not yet "tested" (going to try to add a package to a osx-arm64 migration soon!)
  • Experimental cache is already being tried by some multi-output packages
    • https://github.com/conda-forge/cherab-inversion-feedstock/blob/9aeb59568a2099551ff5e34f433b29a1beb6ee03/recipe/recipe.yaml#L14
  • Bunch of other issues / shortcomings going to be fixed asap in rattler-build
  • IF: When to move to recipe.yaml in complicated recipes. Would rather wait for compiled things until bugs are fixed.
  • https://github.com/prefix-dev/rattler-build/issues/955
  • https://github.com/prefix-dev/rattler-build/issues/952
• WV: Pixi in CI pipelines
  • WV: Why mamba update on CI?
    • IF: Old mamba bug, might be resolved now.
  • https://github.com/conda-forge/conda-forge.github.io/issues/2323
  • Marius tried locks and got shot down - see https://github.com/conda-forge/conda-forge-lockfiles
  • Two separate issues:
    • performance for bootstrapping: lockfiles?
      • Action item: measure how long it takes. Might be different across OSs.
    • local debugging with build-locally.py but with pixi
• MRB: infrachanges for rerendering / linting / version commands
  • webservices now sends all jobs that process recipes (except for team updates which only read text) to GHA actions
  • those GHA jobs run out of conda-forge-webservices actions instead of the actions on repos
  • isolation of recipes is done using separate GHA jobs (which are separate VMs) and also docker containers
  • if you see issues bump me
