Release

Automate the full release cycle: version bump → test → build → commit → push branch → open PR → merge → tag → GitHub Release.

Direct pushes to main are blocked by a branch ruleset. All releases go through a PR.

Preferred GitHub Actions flow

The default release path is now GitHub Actions-driven:

1. Run the Prepare Release workflow (.github/workflows/prepare-release.yml)
2. Review/approve the generated release PR
3. Let GitHub auto-merge the PR after checks pass
4. The Tag Release workflow (.github/workflows/tag-release.yml) tags the merge commit
5. The Release workflow (.github/workflows/release.yml) runs for that tag and publishes the artifacts

The manual flow below remains the fallback/operator path when you need to release outside GitHub Actions.

Version files

All version files must stay in sync. The Rust workspace manifest is the canonical Rust version source, and scripts/bump-version.js (exposed via npm run bump:*) updates the mirrored package versions in one command. The release workflow (release.yml) validates they match:

1. rust/Cargo.toml — workspace package version (Rust source of truth)
2. package.json — root npm package version (mirrors the workspace version) and optionalDependencies.tabctl-win32-x64
3. package-lock.json — lockfile
4. packages/win32-x64/package.json — Windows platform package
5. rust/crates/tabctl/Cargo.toml — main Rust binary (inherits workspace version)
6. rust/crates/host/Cargo.toml — host crate (inherits workspace version)
7. rust/crates/graphql/Cargo.toml — GraphQL crate (inherits workspace version)
8. rust/crates/shared/Cargo.toml — shared crate (inherits workspace version)
9. rust/Cargo.lock — Rust lockfile

Never edit these version fields manually. Always use npm run bump:<kind>.

Prerequisites

• Working tree is clean (git status shows no uncommitted changes)
• On the main branch
• gh CLI is authenticated (gh auth status)
• npm test and npm run build pass

Workflow

Step 1: Pre-flight checks

git status --porcelain
git branch --show-current
gh auth status

If the working tree is dirty, stop and ask the user to commit or stash first. If not on main, warn the user and ask whether to proceed.

Step 2: Determine version bump

Find the last tag and analyze commits since then:

LAST_TAG=$(git tag --sort=-v:refname | head -1)
git log "${LAST_TAG}..HEAD" --oneline --no-decorate

Auto-detect bump type from conventional commits:

Pre-release version handling:

If the current version is a pre-release (e.g. 0.6.0-alpha.9), compute the next version based on what the user requests:

• Next alpha: increment the alpha number → 0.6.0-alpha.10
• Release candidate: 0.6.0-rc.1
• Stable release: 0.6.0
• New minor/major alpha: e.g. 0.7.0-alpha.1 or 1.0.0-alpha.1

For stable versions, use standard semver bumping:

CURRENT=$(echo "$LAST_TAG" | sed 's/^v//')
IFS='.' read -r MAJOR MINOR PATCH <<< "$CURRENT"

# For major bump:
NEW="$((MAJOR + 1)).0.0"
# For minor bump:
NEW="$MAJOR.$((MINOR + 1)).0"
# For patch bump:
NEW="$MAJOR.$MINOR.$((PATCH + 1))"

Step 3: Show plan and confirm

Before making any changes, present a summary and use AskUser to confirm:

Release plan:
  Current version: v{CURRENT}
  New version:     v{NEW} ({BUMP_TYPE})
  Commits:         {N} commits since {LAST_TAG}

  {commit list}

  Steps:
  1. Create branch chore/release-v{NEW}
  2. Update all version files to {NEW}
  3. Run npm test
  4. Run npm run build
  5. Commit: chore(release): v{NEW}
  6. Push branch, open PR
  7. Wait for CI, merge PR (normal merge, not squash)
  8. Tag v{NEW} on main
  9. Create GitHub Release (triggers release.yml → npm publish + binary builds)

Ask the user to confirm the version. Offer the recommended bump plus alternatives. If the user picks a different bump or types a custom version, use that instead.

Step 4: Create release branch

git checkout -b "chore/release-v${NEW}"

Step 5: Update all version files

Use the bump script which updates all version files (package.json, package-lock.json, packages/win32-x64/package.json, 3× Cargo.toml, Cargo.lock) in one command:

# For the recommended bump type:
npm run bump:alpha    # 0.6.0-alpha.9 → 0.6.0-alpha.10
npm run bump:rc       # 0.6.0-alpha.10 → 0.6.0-rc.1
npm run bump:stable   # 0.6.0-rc.1 → 0.6.0
npm run bump:patch    # 0.6.0 → 0.6.1
npm run bump:minor    # 0.6.1 → 0.7.0
npm run bump:major    # 0.7.0 → 1.0.0

If the user chose a custom version that doesn't match a standard bump, update manually:

node scripts/bump-version.js <kind>

Verify the output matches the expected version.

Step 6: Run tests

npm test

If tests fail, stop and report the failure. Do NOT proceed with the release.

Step 7: Build

npm run build

If the build fails, stop and report the failure. Do NOT proceed with the release.

Step 8: Commit

git add package.json package-lock.json packages/win32-x64/package.json \
       rust/crates/tabctl/Cargo.toml rust/crates/host/Cargo.toml \
       rust/crates/graphql/Cargo.toml rust/crates/shared/Cargo.toml rust/Cargo.lock
git commit -m "chore(release): v${NEW}"

All these files are updated by scripts/bump-version.js in Step 5.

Step 9: Push branch and open PR

git push -u origin "chore/release-v${NEW}"
GH_PAGER="" gh pr create \
  --title "chore(release): v${NEW}" \
  --body "Bump all version files to ${NEW}. After merge, tag and create release." \
  --base main

Note the PR number from the output.

Step 10: Merge, tag, and release

Use the existing helper script which waits for CI, merges (normal merge, not squash), tags on main, and creates the GitHub release:

scripts/ci-wait-merge.sh <PR_NUMBER> --tag "v${NEW}"

This script:

1. Waits for all CI checks to pass (gh pr checks --watch)
2. Merges the PR with --merge --delete-branch (normal merge commit)
3. Checks out main and pulls
4. Creates annotated tag v{NEW}
5. Pushes the tag
6. Creates a GitHub release (with --prerelease for -alpha.N / -rc.N versions)

The release triggers the release.yml workflow which builds binaries and publishes to npm.

After completion, display the release URL so the user can review.

Dry-run mode

If the user asks for a dry run (or passes --dry-run), perform Steps 1-3 only: pre-flight checks, version analysis, and show the plan. Do NOT modify any files, commit, tag, push, or create a release.

Abort and rollback

If any step after Step 5 fails (tests, build, commit, push, or PR creation), provide rollback instructions:

# Switch back to main and delete the release branch
git checkout main
git branch -D "chore/release-v${NEW}"

# If PR was created, close it
gh pr close <PR_NUMBER> --delete-branch

# If tag was created locally
git tag -d "v${NEW}"

# If tag was pushed — only with explicit user confirmation
git push origin --delete "v${NEW}"

Safety rules

• NEVER skip tests or build
• NEVER force push
• NEVER push directly to main — always use a PR
• NEVER squash merge release PRs — use normal merge to preserve commit identity
• NEVER create a release without user confirmation
• NEVER delete existing tags or releases without explicit user request
• If --dry-run, do NOT modify anything
