* fix: Prevent Docker multi-arch race condition (fixes #328) Resolves race condition where docker-build.yml and release.yml both push to 'latest' tag simultaneously, causing temporary ARM64-only manifest that breaks AMD64 users. Root Cause Analysis: - During v2.20.0 release, 5 workflows ran concurrently on same commit - docker-build.yml (triggered by main push + v* tag) - release.yml (triggered by package.json version change) - Both workflows pushed to 'latest' tag with no coordination - Temporal window existed where only ARM64 platform was available Changes - docker-build.yml: - Remove v* tag trigger (let release.yml handle versioned releases) - Add concurrency group to prevent overlapping runs on same branch - Enable build cache (change no-cache: true -> false) - Add cache-from/cache-to for consistency with release.yml - Add multi-arch manifest verification after push Changes - release.yml: - Update concurrency group to be ref-specific (release-${{ github.ref }}) - Add multi-arch manifest verification for 'latest' tag - Add multi-arch manifest verification for version tag - Add 5s delay before verification to ensure registry processes push Impact: ✅ Eliminates race condition between workflows ✅ Ensures 'latest' tag always has both AMD64 and ARM64 ✅ Faster builds (caching enabled in docker-build.yml) ✅ Automatic verification catches incomplete pushes ✅ Clearer separation: docker-build.yml for CI, release.yml for releases Testing: - TypeScript compilation passes - YAML syntax validated - Will test on feature branch before merge Closes #328 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com> * fix: Address code review - use shared concurrency group and add retry logic Critical fixes based on code review feedback: 1. CRITICAL: Fixed concurrency groups to be shared between workflows - Changed from workflow-specific groups to shared 'docker-push-${{ github.ref }}' - This actually prevents the race condition (previous groups were isolated) - Both workflows now serialize Docker pushes to prevent simultaneous updates 2. Added retry logic with exponential backoff - Replaced fixed 5s sleep with intelligent retry mechanism - Retries up to 5 times with exponential backoff: 2s, 4s, 8s, 16s - Accounts for registry propagation delays - Fails fast if manifest is still incomplete after all retries 3. Improved Railway build job - Added 'needs: build' dependency to ensure sequential execution - Enabled caching (no-cache: false) for faster builds - Added cache-from/cache-to for consistency 4. Enhanced verification messaging - Clarified version tag format (without 'v' prefix) - Added attempt counters and wait time indicators - Better error messages with full manifest output Previous Issue: - docker-build.yml used group: docker-build-${{ github.ref }} - release.yml used group: release-${{ github.ref }} - These are DIFFERENT groups, so no serialization occurred Fixed: - Both now use group: docker-push-${{ github.ref }} - Workflows will wait for each other to complete - Race condition eliminated 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com> * chore: bump version to 2.20.1 and update CHANGELOG Version Changes: - package.json: 2.20.0 → 2.20.1 - package.runtime.json: 2.19.6 → 2.20.1 (sync with main version) CHANGELOG Updates: - Added comprehensive v2.20.1 entry documenting Issue #328 fix - Detailed problem analysis with race condition timeline - Root cause explanation (separate concurrency groups) - Complete list of fixes and improvements - Before/after comparison showing impact - Technical details on concurrency serialization and retry logic - References to issue #328, PR #334, and code review 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com> --------- Co-authored-by: Claude <noreply@anthropic.com>
