(Original in-person discussion at SciPy 2023 was around discovering specific AVX-512, AES-NI, and ARM instructions.) - [X] (BH) Where is the best place to learn about/peek into conda-forge build automation? - Feedstock builds: conda-smithy provides the starting configuration, conda-forge-ci-setup handles some stuff at runtime, docker-images creates the base image for Linux. Automation around feedstocks... regro/cf-scripts is the start. - https://cf-infra-docs.netlify.app/docs/fundamentals/life-cycle/ for some big picture docs (non-official) - [X] (JK) m2 recipes - https://github.com/conda-forge/staged-recipes/pull/24112 - https://github.com/conda-forge/m2-builds - conda-msys2:matrix.org - [x] (JK) AlmaLinux 8 - CDTs need to be setup - [x] (JK) macOS 10.13 - https://github.com/conda-forge/conda-forge.github.io/issues/1844 - https://github.com/conda/conda-build/pull/4999 - Needs reviews - [x] (JK) Windows ARM - compatibility status? - conda-forge usage - (IF) Got Windows ARM machine - (IF) Need to gen GHA token to give to them for CI setup (planned at end of month) - (IF) Will need to some cross-compilation to support building some of the packages for Windows ARM (from x86_64) - (MRB) Load? - (IF) Not worried about this as ramp up time will be long - (IF) They also will give us more if needed - (JRG) Have admin service logic to add/remove CI services - [X] (HV) Asking Microsoft for more CI jobs - (JRG) Moving to GHA as an option - (MRB) Need to be careful having jobs that generate jobs on GHA (DoS risk) - [X] (JK) Conda/conda-build/mamba/boa/Miniforge - (JRG) Can use `conda-libmamba-solver` in `conda-build` (starting w/23.9.0) - This has also been tested in staged-recipes - (WV) Regarding `boa`, might be best to move `conda-build` with `conda-libmamba-solver` - (HV) Will this allow us to update `conda-build` in feedstocks - Yes +3 - (JRG) Can also opt-in with `conda-forge.yml` - Link: https://conda-forge.org/docs/maintainer/conda_forge_yml.html#conda-build-tool - (JK) Let's test on feedstocks a bit and see how it goes - [X] (CA) CDN issues - granular package delay monitoring coming soon - some packages can't be downloaded from CDN - Files were uploaded, but no release record was added - Now working on fixing the 20-30 packages affected in cf - Also adding logic now to track delay time - - [X] (JRG/WV) CZI EOSS6 LOI submission: https://github.com/conda-forge/conda-forge.github.io/pull/2019 ### Pushed to next meeting - [ ] (HV) archspec-enabled packages - [ ] (JK) m2 recipes ### CFEPs - [ ]
