Agenda¶
Standing items¶
[x] (CJ) budget, also finance subteam creation
https://github.com/conda-forge/conda-forge.github.io/pull/1093
[x] intros for new folks on the call
Your new agenda items¶
Stuff from last week that we didn’t get to¶
[x] (CL) msys2 packages
Anaconda deciding on update plans for “defaults” channel
No immediate action needed at this time
[x] (CJ) rebuild migration automerges default
Currently either automerge is (org-wide?) on or off, but it would be good to allow ppl to choose to automerge only for rebuilds and not version updates
These automerges may be safer than version automerges, since the deps don’t change and the build is more likely to fail if the package would be broken.
https://github.com/regro/cf-scripts/pull/1063
Overall response is positive, we need to document/announce this change
[x] (CJ) s390x support
https://github.com/conda-forge/conda-smithy/issues/1359
What is the minimum level of support we need before we would accept this
Should outline concerns in issue
Ask to first add platform to numpy/scipy CI?
Ask to build gcc?
[x] What should we do with feedstocks that are not being maintained?
Allow people who use package to step up to maintainance
Should be aggresive on archiving feedstocks
And remove maintainers
Advertise un-maintained feedstocks (in docs?)
Notify for when a feedstock repo depends on something archived?
todo: cleanup teams post removal of users
[x] (FF) new conda-build release that fixes the Windows prefix issue
https://github.com/conda/conda-build/issues/3909#issuecomment-62658654
coming soon, JJH will keep core updated on progress
[x] (MRB) pinning epochs draft CFEP
see the draft here: https://hackmd.io/N1hoJGJBSqGTFd83pxCyYA
idea is to declare some pinning file as a pinning epoch
then we render a recipe with the epoch’s pinnings and the latest pinnings
discussion around burden on maintainers
opt-in vs opt-out model
discussion around how many of these we want to support
current suggestion (Uwe) is at most 2 pinnings + latest
tag pinning epochs every 6 months to a year or so which creates a ~yearly deprecation cycle
the bot will need to issue PRs to update feedstocks to next pinnings epoch as we move them along
Alternative to build for multiple version of boost
Make boost a matrix
1.70 (again) and 1.72
Keep a pinned boost version for at least [some time]?
Should we do similar for ICU ?
Uwe seemed to indicate no
[ ] (ED) Welcome packets for new members and contributors? – Delayed
new contributors to staged-recipes
stickers mailed to an address of their choosing?
Staged-recipes
new contributors plus a mug
Subteams?
As above plus any subteam specific stuff (e.g., maybe we need a bot sticker)
Core
staged-recipes plus a tshirt
Concerns:
cost
who would mail stuff
privacy around people giving us a mailing address

[ ] (KK) Remove deprecation/warning of pre-link scripts in conda-build
Warning currently swallows messages from our (NVIDIA) testing
Used in conda forge packages currently according to jakirkham
Would be good to allow packages with proprietary licenses to display some message before package is actually installed
NVIDIA legal would prefer this for CUDA related packages, and want to pave the way for shipping compiler, headers, and other EULA protected bits
Active votes¶
Subteam updates¶
Bot¶
ARM¶
POWER¶
CUDA¶
Docs¶
staged-recipes¶
website¶
security+systems¶
[ ] still need to finish CFEP-13 (can move ahead now that latest smithy is out)
CI infrastructure¶
Compiler upgrade¶
CFEP updates¶
Open PRs¶
cfep-04 X11 and CDT policy
INACTIVE - Merge in with some inactive-esque status?
Needs new champion. Thanks for your work on this pkgw! Has unaddressed comments from pkgw as from Jan 10, 2020
cfep-06 Staged-recipes review lifecycle
INACTIVE - Merge in with some inactive-esque status?
Lingering comment from @saraedum. @jakirkham, can you reply? Has unadressed comment from @saraedum from Jan 8, 2020
(MRB) The stalebot has solved the worst of the issues here. I think we could defer this one permanently.
cfep-10 Feedstock statuses, unmaintained
INACTIVE - Merge in with some inactive-esque status?
Needs another review. Has unaddressed updates from pkgw as of Jan 11, 2020
cfep-12 Removing packages that violate the terms of the source package
Stalled since May 26, 2020
Active debate about moving to “broken” vs deleting from conda-forge channel
Active vote, ends on 2020-03-11
What were the results of the vote?
Did we hear back from NumFOCUS?
cfep-17 Handling pin backports and dependency rebuilds
Stalled debate about implementation details between Isuru, CJ and Matt
UPDATE 2020-07-22: We in principle have agreement to render the extra pinnings needed directly in the feedstock on a temporary basis (i.e., until the migration has ended).
Discussion¶
Check in on previous action items¶
Copy previous action items from last meeting agenda.
This meeting¶
[ ] Figure out how to communicate breaking changes to users. Likely should open up an issue immediately for futher discussion. Ping @kkraus, plus capture notes from further up in these meeting notes
[ ] (Eric) TODO: Make strict an option in conda_forge.yaml and turn it on by default. Open issue in conda-smithy
Last meeting¶
2 meetings ago¶
[ ] Eric to add a new page to our docs around how to engage with conda-forge and affiliated in a commercial relationship.
[ ] Eric will get the NVBug link from Keith and archive it in the conda-forge google drive.
[ ] John K. will update the cuda toolkit feedstock on the git repo to note the NVBug link to the internal NVIDIA issue tracker
[ ] Jonathan will update docs to note that some non-exhaustive list of packages (like cuda-toolkit, MKL, etc.)
[ ] Jonathan will review this PR
3 meetings ago¶

https://github.com/conda-forge/conda-forge.github.io/issues/954
[ ] (ED) Who we are page? Some combination of a FAQ and a who is everyone. FAQ things like:
who’s the POC for CF <> Anaconda, CF <> NumFocus, CF <> Azure
who’s the POC for the various subteams?
Informal information: roles, day jobs, bios, the whole nine yards, why you’re here, etc.
Public or internal? I don’t really care either way. Anyone feel strongly one way or the other?
opt-in to public bios
software carpentry has a large number of instructors and has https://carpentries.org/instructors
some concern about “yet another place to keep stuff up to date”
[ ] (CJ) Form finance subteam
[ ] (ED) document strategies for reproducible environments using conda-forge
[ ] (UK) Static libraries stuff
[ ] Add linting hints to builds to find them
[x] Recommend how to package them -> CFEP-18
[x] We should write docs saying we don’t provide support and this is a bad idea. -> CFEP-18
