2018-09-04 conda-forge meeting

Pinned Items

New items

  • Meet with NumFOCUS RE: Fiscal sponsorship
  • Need .la removal for compiler rebuilds

Existing Items

  • Compiler migration has started (finished in Q1 2019)
  • Votes/discussion in progress or need start:
  • Conda 4.5.9 (features thing):
    • Filipe asking for option to error if conda tries to use packages from a lower-priority channel over their higher priority channel. Allow fallback, but only for things that don’t exist.
  • Dougal raising issue with conda-build creating noarch packages. Conda-build wants to use new python, then runs into unsatisfiable deps (python 3.7 isn’t totally built out yet).
  • Discuss the recipes syncing between defaults and conda-forge and some issues we are facing:
    • large number of patches
    • the use of cdt jinja (ping Peter Williams on the benchmark @pkgw)
    • new compiler specific stuff on the build scripts
    • multiple outputs and new names: curl/libcurl, etc
    • the use of features (
  • Sharing passwords (to start off the meeting next time)
    • Try something out and move on to more interesting problems
    • Let’s try KeyBase. Eric D. just sent out invites to most of the core team.
  • Establish next steps/action items/gh issues for migrations
    • MVN will coordinate with CJ on issuing prs for the things that need compilers that don’t actually call it out nicely.
    • Parse graph find everything which could be py 3.7 but no compiler and not noarch, run rebuild on that.
    • May need to have two versions of pinnings + smithy whilst graph is being rebuilt.
  • Decide on a policy for when maintainers stop maintaining
    • Come back to later
  • Related to 2k-ish pending bot PRs…
    • MVN will give CJ a list of merge-conflicted feedstocks that were closed and not merged.
    • Auto close out of date PRs
    • Auto delete closed/merged bot PR
  • run_exports vote
  • Expiring (i.e., auto-closing with a bot) "old" PRs into staged-recipes?
    • Put on label, add message (stale), ping relevant parties to close
    • Decide on policy
  • Finding a good solution to sharing passwords among core
  • Build packages on C3I and upload to conda-forge
    • Make is missing from the base image for PowerPC internal to Anaconda. Fun times!
    • Mike is open to other people helping with this. If interested, reach out! Helping means trying recipes, debugging any issues, and resolving any merge conflicts that have happened since Mike pulled them in last. Moving target.
    • Packages that have been built - these may need more work regarding versions. The graph was computed with the versions, but probably should have ignored them. When a pin is older than a newer recipe, the upstream recipe gets missed as a real dependency because of the version mismatch.
  • Making the agenda and notes public again.
    • John will see if we can make dropbox paper readable by the world
    • other options are to just post the notes somewhere public after the meeting
  • conda-forge blog

Discussed Items


  • NumFOCUS summit:
    • Marius and Anthony attending (maybe CJ)
  • Subgroup proposal: have smaller groups that meet outside of core meetings with different frequency
    • Each of these need to be put up as a proposal (to, which then needs a core vote for creation. Each proposal should have a scope of the group and initial members, as well as how the group is expected to coordinate and communicate.
    • Proposed initial groups:
      • bot: people responsible for bot architecture, implementation, maintenance. NOT actual uses of bot (e.g. creating large migrations)
