### Your __new__() agenda items | ||
|
||
- [X] (JK) NumPy 2.0 | ||
- Discussion about how to get more info about NumPy version used in a build | ||
- https://github.com/numpy/numpy/pull/24861 | ||
- https://github.com/conda-forge/conda-forge.github.io/issues/1997 | ||
- [X] (HV) archspec-enabled packages | ||
- leaving lots of perf on the table; distros moving to x64-v2 or [even](https://www.phoronix.com/news/CentOS-ISA-Experiment-Perform) v3 baseline () | ||
- [CF issue](https://github.com/conda-forge/conda-forge.github.io/issues/1261) open since ~2.5yrs; [CEP issue](https://github.com/conda-incubator/ceps/issues/59) a few months ago -- next steps? | ||
- (IF,CHL) We could probably re-purpose the existing `__archspec` virtual package to expose/proxy the HWCAPS/feature level; would not require additional changes conda to get some support for tuned packages | ||
- See https://github.com/conda-incubator/ceps/issues/59#issuecomment-1636844274 | ||
- https://en.wikipedia.org/wiki/X86-64#Microarchitecture_levels | ||
- (CHL) CEP potentially goes way deeper and would expose things like individual CPU feature flags. (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 | ||
