CI: combine nightly and PR C++ test matrices by vyasr · Pull Request #24135 · NVIDIA/cudf

vyasr · 2026-09-11T21:10:43Z

Description

Make the nightly test.yaml C++ test job run the union of the nightly and pull-request matrices. This lets nightly CI populate JIT caches for every C++ test configuration used by PR CI, while pr.yaml continues to run only its smaller pull-request matrix. Ideally we would reduce the overhead of JITting in CI, but until we have evaluated how we can achieve that caching is critical to keep CI times manageable.

📝 Summary

Summary by CodeRabbit

Chores
- Updated the automated test workflow to use the shared workflow’s current main revision.
- Nightly and pull-request test coverage remains enabled.

Walkthrough

The conda-cpp-tests job now uses the shared workflow revision main. It retains the nightly,pull-request matrix types and the existing build configuration.

Changes

C++ test workflow reference

Layer / File(s)	Summary
Configure C++ test workflow reference `.github/workflows/test.yaml`	The `conda-cpp-tests` job now references the shared workflow at `main` while retaining its matrix and build settings.

Priority: ⬇️ Low

Estimated code review effort: 1 (Trivial) | ~2 minutes

Change: Other

Merge Risk: 🟡 Moderate · up to eee81

Nightly CI can run later upstream workflow changes with its existing secrets and OIDC credentials. Pinning the tested workflow revision should be addressed before merge.

Run https://github.com/NVIDIA/cudf/actions/runs/34648915193?pr=24135 demonstrates that the shared-workflows change does work as expected when I tell this PR to run both pr and nightly matrices.

Pin the shared workflow to the tested commit.

@main is mutable. This job grants id-token: write and inherits the caller's secrets. A later upstream change or compromise can execute unreviewed code with those credentials. Replace @main with the full commit SHA for the tested revision.

Depends on rapidsai/shared-workflows#637. I like the concept and posed some other ideas on that PR.
