NumFOCUS

Application for NumFOCUS affiliation of SageMath

sage-devel post Jan 13, 2024 with draft application, links to previous discussions.

Next target date: Apr 15, 2024

Integration with the existing ecosystem of NumFOCUS tools

Integration with NumFOCUS Sponsored Projects

The sponsored projects IPython, Jupyter, Matplotlib, NetworkX, NumPy, SciPy, SymPy are dependencies of SageMath. Additionally, volunteers maintain conda-forge packaging of SageMath.

IPython and Project Jupyter are essential dependencies of SageMath:

• TODO shared history
• https://github.com/ipython/ipython/blob/main/.github/workflows/downstream.yml

Integration with NumFOCUS Affiliated Projects

The affiliated projects CVXPY, Cython, igraph are dependencies of SageMath.

Cython is an essential dependency of SageMath:

• The Sage library contains over 500 Cython modules.
• TODO shared history
• Sage switched to the Cython 3.0 series in Sage 10.2, released December 2023.

Possible integration with Spack, package manager for HPC systems:

• This could improve the reach of SageMath to use on HPC systems, although viable alternatives such as conda-forge exist.
• Using Spack Packages as an upstream for SageMath's dependencies:
  • Add system package information files SAGE_ROOT/build/pkgs/*/distros/spack.txt
  • Add portability tests for building in Spack environments, e.g. based on spack containerize
• Downstream packaging of SageMath in Spack Packages: Various dependencies of SageMath already exist but are not up to date (e.g. gmp, suite-sparse) and are marked as "looking for a maintainer".

Additional requirements for Sponsored Project status

Project governance

TODO: Describe the Maintainers role: Duties, privileges, appointment procedure

• Duty (daily): Approve workflow runs for PRs by new contributors that are waiting for approval
• Duty (weekly): Assign closed issues, merged PRs without release milestone to the current milestone
• Duty (weekly): Monitor the workflows CI Linux (default), push to Docker Hub, publish to GH Releases and PyPI; hot-fix and restart if necessary
• Duty (weekly): Monitor the long-running CI workflows of development releases (check for broken portability)
• Duty (monthly): Monitor the long-running CI workflows of development releases (check for broken optional packages)
• Duty (monthly): Organize preparation of Release Tours

TODO: Document governance of other projects hosted on https://github.com/sagemath/
