CI: shrink checkouts via shallow / treeless partial clones - #2177
Merged
Conversation
Of the 15 workflow checkouts that used fetch-depth: 0, only 7 actually need the commit graph (setuptools-scm, git merge-base, git worktree), and none of them need historical blobs. The remaining 8 either do no git operations or only need tag resolution. - 6 sites with no local git ops: fetch-depth: 1 (ci.yml ci-vars, build-docs.yml, release-upload.yml, release.yml check-tag, release-cuda-pathfinder.yml upload-assets, coverage.yml coverage-windows) - 2 sites that resolve a tag to a SHA via lookup-run-id: fetch-depth: 1 + fetch-tags: true (release.yml determine-run-id, release-cuda-pathfinder.yml prepare) - 7 sites that need the commit graph but not blobs: fetch-depth: 0 + filter: blob:none (build-wheel.yml, ci.yml detect-changes, cleanup-pr-previews.yml, coverage.yml coverage-linux, coverage.yml build-wheel-windows, test-sdist-linux.yml, test-sdist-windows.yml) ClosesNVIDIA#2091

CI is fully green, and the checkout-step speedup is significant. Sampling representative jobs from this PR's run (
Every checkout is now seconds rather than minutes. Cumulative compute time saved per CI run across the full matrix (6 linux-64 + 6 linux-aarch64 + 6 win-64 builds, 2 sdist jobs, No correctness issues observed: -- Leo's bot |

PR #2177 made the release workflow checkout shallow, so the dry-run tag validation now needs tags fetched explicitly while keeping history shallow.

* Check release notes for planned backports Require mainline cuda-bindings and cuda-python releases to explicitly declare a planned backport tag or mark it not planned. Keep actual backport releases unblocked while surfacing missing notes as warnings, and preserve docs builds for older tags that still use ci/versions.json. * Add dry-run release workflow mode Validate release docs, archives, and wheels without publishing to GitHub Releases, GitHub Pages, TestPyPI, or PyPI. * Allow dry-run docs branch deployment Add an explicit dry-run docs branch input so release dry-runs can optionally write generated docs to a seeded non-production branch while keeping artifact-only dry-runs as the default. * Default release workflow dispatches to dry-run Make dry-run the first and default release action so production publishing must be deliberately selected for manual release workflow runs. * Constrain dry-run docs deploy branches Require optional dry-run docs deployments to target a non-production gh-pages-* branch so manual release dry-runs cannot accidentally publish docs to production or source branches. * CI: fetch tags for release dry-run validation PR #2177 made the release workflow checkout shallow, so the dry-run tag validation now needs tags fetched explicitly while keeping history shallow. * CI: document release dry-run retest matrix Add workflow-local guidance for validating non-trivial release workflow changes with focused dry-run coverage.

Summary
Closes#2091.
15 workflow checkouts used
fetch-depth: 0(full clone with every blob in history). The audit in #2091 showed only 7 actually need the commit graph (setuptools-scm,git merge-base,git worktree), and none need historical blobs. The remaining 8 either do no local git operations or only need tag resolution. This PR applies the three patterns from that audit.Patterns applied
