  • Conda talk submitted to US RSE 2023, will submit conda-forge tutorial in the next week
  • CHL submitted "conda and friends" sprint proposal to SciPy 2023

• conda-build 3.24.0 released! 🎉

  • https://github.com/conda/conda-build/releases/tag/3.24.0
  • 6 new contributors!

New Agenda Items 📰

• (TH) Conda Version Support CEP: https://github.com/conda-incubator/ceps/pull/25
  • Revised from an earlier attempt
  • Now, we only want to support the most recent version
  • Ready to be discussed and voted on
  • Extension of CEP-8 and -9
  • (JK) How would this impact API that tools like conda-smithy depend on?
    • Changes should follow the published deprecation policy.
    • Need to restart discussion about API: https://github.com/conda/conda/issues/11925
• (CHL) Should we deprecate fix the conda/schemas repo?
  • What CEPs do we need to write?
  • (JL) Should there be a spec/CEP working group to move this forward?
  • Leaning hard towards fixing the schemas instead of deleting them wholesale
  • Some are only partly implemented. Some are not.
  • (CHL) happy to lead cleanup.
  • In the meantime, flag them as inaccurate, but also say we are actively working on it.
• (DH) Need feedback on repodata.state.json rename CEP, also adds locking and modifies cache revalidate checks. https://github.com/conda-incubator/ceps/pull/48/files
• (JL) conda-build release policy
  • part of the larger initiative to ramp up on maintenance: https://github.com/conda/conda-build/issues/4697
  • recent code changes broke conda-forge scripts (NameError)
  • ~140 releases of conda-build 3.x!
  • skeleton and index should be going out
  • CEP 8 and 9 look promising for conda, also for conda-build?
  • Draft: conda-build adopts CEP 9 with an accelerated deprecation cycle without pending deprecation and just one regular release between deprecation and removal, resulting in a 2-5 months depreciation window
  • Alternatives:
    • aggressively follow SemVer (e.g. conda-build 4.0 drops skeleton and index)
    • rewrite rather than trying to fix?
    • ???
  • How should we think about conda-build and mamba-build (boa)?
  • (ED) What learnings can we as a community gather about the ways people have used Jinja and selectors in recipes?
    • (JK) Common Jinja uses: reduce repetition; cross-platform test scripts
  • Activation scripts (unsafe!) mostly export env vars. Make it more powerful (simple templating to depend on other variables).
    • (JK) Maybe run_env in meta.yaml? Similar to the existing script_env.
      • https://github.com/conda/conda-build/issues/4833
• (ED) going to work on a few CEPs, anyone else (besides Jaime cause he already agreed) interested in co-authoring?
  • two first:
    • cep_A: env.yaml spec
    • cep_B: lock file spec
  • then:
    • cep_C: lock-file based env management
  • reviewers:
    • Filipe, Cheng, Jannis, Srivas
  • notes:
    • JK: sophia wrote a doc
      • Found the doc links. Though am unable to open them. Appear to be owned by Anaconda (also fwded to Eric)
      • https://docs.google.com/document/d/1-XNmPJJ0XqNW5CZm7nHwCzOSOs3PdiuOCUmJ8Yuimz0

    • conda list, conda env list
• (DPC) Should we officially allocate the first 5 minutes of every meeting to socialization?
  • 12:00-12:05? or 12:05-12:10?
  • ED: for cf meetings i always just assume first 5 mins is waiting for folks to join
  • No clear decision
  • Could make it chair's choice?
    • Do we know in adavance who the chair will be?
