rocky-release

name: rocky-release description: Tag-namespaced release workflow for the Rocky monorepo. All three artifacts (engine, dagster-rocky, vscode) are CI-driven — land a release PR with the version bump + CHANGELOG, tag the merged commit, push the tag, and the matching release workflow handles everything. Use when cutting any Rocky release.

Rocky release workflow

Three artifacts ship independently from one monorepo, each with its own tag namespace:

Never tag a release as bare v0.1.0 — the tag namespace is how engine/install.sh, engine/install.ps1, and downstream consumers filter for their artifact.

When to use this skill

• Cutting any Rocky release (engine, dagster, vscode)
• Debugging a release failure — the failing job is always in the relevant *-release.yml logs
• Deciding whether a release needs the local-build fallback (only when CI runner credits are exhausted or a workflow itself is broken)

The flow: release PR → merge → tag → push

All three artifacts follow the same pattern:

1. Land a release PR that bumps the version file(s) + updates the changelog.
2. Tag the merged commit with the namespaced tag (engine-v*, dagster-v*, vscode-v*).
3. Push the tag — this triggers the matching *-release.yml workflow.

The workflow handles the GitHub Release creation, build, and (for dagster/vscode) the publish to the external registry.

scripts/release.sh + the just release-engine|dagster|vscode recipes survive as local-build fallbacks when CI is unavailable. The local path also works — it creates the GH Release + uploads artifacts, and ensure-release is idempotent.

Engine release (default: just tag and push)

# 1. Bump versions + changelog in a PR, merge to main (see "Pre-flight" below).
# 2. From main at the commit you want to release:
git tag -a engine-v0.2.0 -m "Release engine-v0.2.0"
git push origin engine-v0.2.0

That's it. The tag push triggers engine-release.yml, which:

1. ensure-release — creates the engine-v0.2.0 GitHub Release if missing (--generate-notes).
2. build matrix — runs on macos-14, ubuntu-24.04, and windows-2022. Each produces a tarball (or .zip for Windows) named rocky-<target>.tar.gz.
3. checksums — generates SHA256SUMS and uploads it alongside the binaries.

Total elapsed: ~15–25 min. Watch with:

gh run watch $(gh run list --workflow=engine-release.yml --limit=1 --json databaseId --jq '.[0].databaseId')

After the run, verify:

• gh release view engine-v0.2.0 --repo rocky-data/rocky shows 5 platform archives + SHA256SUMS
• engine/install.sh and engine/install.ps1 resolve the new version (they filter releases by the engine-v* prefix)

Engine fallback: local build (only when CI is unavailable)

When GitHub Actions credits are exhausted or the CI matrix is broken, scripts/release.sh (exposed as just release-engine <version>) builds on your laptop:

just release-engine 0.2.0
# or:
./scripts/release.sh engine 0.2.0

This builds macOS locally (cargo --release), cross-builds Linux via cargo-zigbuild or Docker (scripts/build_rocky_linux.sh), creates the GitHub Release with --generate-notes, uploads macOS + Linux tarballs, then pushes the tag. The tag push still triggers engine-release.yml — if CI is healthy it'll re-build everything and overwrite the local uploads; if CI is broken but the tag-push side-effect you want is just the release itself, the local upload suffices.

Only reach for this when CI is genuinely unavailable. It's slower, riskier, and produces artifacts signed by your laptop instead of the GitHub runner.

Dagster release (default: just tag and push)

# 1. Bump pyproject.toml + CHANGELOG in a PR, merge to main.
# 2. Tag the merged commit and push:
git tag -a dagster-v0.4.0 -m "Release dagster-v0.4.0"
git push origin dagster-v0.4.0

The tag push triggers dagster-release.yml, which:

1. ensure-release — creates the dagster-v0.4.0 GitHub Release if missing.
2. build — uv build produces the wheel + sdist, uploads them to the GH Release.
3. publish — uv publish pushes to PyPI via OIDC (trusted publisher; no token in repo secrets).

Dagster fallback: local build

just release-dagster 0.4.0                # GH release only
just release-dagster 0.4.0 --publish      # + PyPI via UV_PUBLISH_TOKEN or ~/.pypirc

The local path is idempotent with CI — ensure-release detects an existing release. Only reach for this when the CI workflow itself is broken.

VS Code release (default: just tag and push)

# 1. Bump package.json + CHANGELOG in a PR, merge to main.
# 2. Tag the merged commit and push:
git tag -a vscode-v0.3.0 -m "Release vscode-v0.3.0"
git push origin vscode-v0.3.0

The tag push triggers vscode-release.yml, which:

1. ensure-release — creates the vscode-v0.3.0 GitHub Release if missing.
2. package — npx vsce package produces the VSIX, uploads it to the GH Release.
3. publish — vsce publish pushes to the VS Code Marketplace using the VSCE_PAT repo secret.

VS Code fallback: local build

just release-vscode 0.3.0                 # GH release only
just release-vscode 0.3.0 --publish       # + Marketplace via local VSCE_PAT

Prerequisites

gh must be authenticated against rocky-data/rocky with release-write permission for all paths.

Pre-flight: what to check before tagging

Runs before any release:

# 1. Everything builds + tests
just build
just test
just lint

# 2. Codegen is clean (no drift)
just codegen
git status     # should show no diff

# 3. Changelog updated
# For engine releases: engine/CHANGELOG.md
# For dagster: integrations/dagster/CHANGELOG.md
# For vscode: editors/vscode/CHANGELOG.md

# 4. Version numbers bumped
# engine:  every engine/crates/*/Cargo.toml + engine/rocky/Cargo.toml (~19 files)
# dagster: integrations/dagster/pyproject.toml
# vscode:  editors/vscode/package.json

Version bump + tag commit

Rocky uses a single "release" commit per artifact that bumps the version file + updates the changelog. Land it as a PR to main, not a direct push:

chore(engine): release 0.2.0
chore(dagster): release 0.4.0
chore(vscode): release 0.3.0

For engine releases, the PR touches ~19 Cargo.toml files — one per crate, plus engine/rocky/Cargo.toml. rocky-bigquery is tracked on its own version track (currently 0.1.0) and is not bumped by the engine release PR; prior releases followed the same pattern.

Neither CI (engine-release.yml) nor scripts/release.sh bump versions for you — that's a manual step before the tag. scripts/release.sh WILL refuse to proceed if the tag already exists (confirm_tag() in release.sh); engine-release.yml won't, but the ensure-release job will silently attach to the existing release.

Common pitfalls

• Forgetting the namespace: v0.2.0 instead of engine-v0.2.0. The install scripts filter by prefix; a bare tag is invisible to them.
• Wrong commit tagged: verify git log -1 before tagging — the tag captures HEAD, not main.
• Missing Cargo.toml bumps: every crate in engine/crates/* must bump (except rocky-bigquery). Grep for the old version before pushing the release PR: grep -rn '^version = "1.2.0"$' engine --include="Cargo.toml" should return zero after the bump.
• Dirty codegen: just codegen produced a diff that wasn't committed — codegen-drift.yml CI retroactively fails.
• Docker not running (fallback only): scripts/build_rocky_linux.sh silently falls back to zigbuild which has its own issues with ring on newer Rust. The --docker flag forces the Docker path.
• Stale binary in vendor/: downstream consumers that vendor the rocky binary via scripts/vendor_rocky.sh need a re-run after a release if they pin to a vendored copy.

CI surface

Path-filtered workflows in .github/workflows/:

• engine-ci.yml — test + clippy + fmt on every PR touching engine/**
• engine-weekly.yml — coverage (tarpaulin) + cargo-audit, Monday schedule + manual dispatch
• engine-bench.yml — only PRs labeled perf touching engine/crates/** or engine/Cargo.*
• engine-release.yml — full 5-target matrix build on tag engine-v* push. Owns the GitHub Release creation + binary uploads + SHA256SUMS.
• engine-docs.yml — build + deploy Astro docs from docs/ to GitHub Pages
• codegen-drift.yml — fails any PR where committed bindings drift from just codegen output

Post-release checklist

• gh release view <tag> shows all expected artifacts (5 for engine + SHA256SUMS; 2 for dagster; 1 for vscode)
• Install script (engine/install.sh or install.ps1) resolves and installs the new version on a clean machine
• Downstream consumers that vendor the binary + Python wheel atomically have been updated — see scripts/vendor_rocky.sh for the vendoring workflow
• Changelog is on main (it merged with the release PR, but double-check)
• Announcement, if public-facing (blog, release notes)
