Updates

• The macOS CI stacks were re-enabled this week.

• We are working on updating our CI pipelines to use the newly introduced buildcache views feature (spack-packages PR #2947).

  • We discussed strategies to mitigate race conditions when attempting to append to a view index. It looks like we can use an If-Match header to solve this problem.

• We're excited about spec groups (spack PR #51891). We think they will help us reorganize our GitLab CI stacks into common, hierarchical sets. More immediately, we expect this feature to help us improve CI turnaround time by reducing the number of build jobs in our existing stacks.

• We're working on making ruff available from a bootstrap cache so we can use it for spack style.

  • We're invesigating an issue where rust gets pulled into the build graph when we think it shouldn't, as it's a run dependency of a build dependency of ruff.

• Ingress NGINX has been deprecated, so we're transitioning to use Gateway API instead for our Kubernetes cluster.
