CI/CD Improvements Summary

🚀 Enhanced Workflows

1. Main Build Workflow (build-ostree-backports.yml)

Key Improvements:

• ✅ Matrix Strategy: Proper multi-distribution support with dynamic matrix generation
• ✅ Manual Triggers: Support for single distribution or all distributions
• ✅ Better Error Handling: Comprehensive error checking and exit codes
• ✅ Detailed Logging: Step-by-step progress with distribution-specific context
• ✅ Upload Statistics: Success/failure counters with warnings
• ✅ Package Path Configuration: Distribution-specific upload paths

New Features:

• build_all parameter for building both distributions simultaneously
• Distribution-specific package upload paths (noble/main, trixie/main)
• Enhanced error reporting with GitHub Actions warnings
• Improved source download with error checking

2. Test Workflow (test-build.yml)

Purpose:

• Quick validation of build process
• Tests source download from both distributions
• Verifies source extraction and changelog modification
• Fast feedback before full builds

Features:

• Manual trigger with distribution selection
• Step-by-step validation
• Clear success/failure reporting

🎯 Manual Trigger Options

Single Distribution Build

workflow_dispatch:
  inputs:
    target_distro: noble  # or trixie
    build_all: false

All Distributions Build

workflow_dispatch:
  inputs:
    target_distro: noble  # ignored when build_all=true
    build_all: true

Test Mode

workflow_dispatch:
  inputs:
    target_distro: noble  # or trixie

📊 Matrix Configuration

Ubuntu Noble

- target_distro: noble
  distro_type: ubuntu
  source_release: questing
  target_release: noble
  backport_suffix: ~noble1
  pool_url: http://archive.ubuntu.com/ubuntu/pool/universe/o/ostree/
  sources_list: "deb-src http://us.archive.ubuntu.com/ubuntu/ noble main universe"
  package_upload_path: noble/main

Debian Trixie

- target_distro: trixie
  distro_type: debian
  source_release: sid
  target_release: trixie
  backport_suffix: ~trixie1
  pool_url: http://deb.debian.org/debian/pool/main/o/ostree/
  sources_list: "deb-src http://deb.debian.org/debian/ trixie main contrib non-free"
  package_upload_path: trixie/main

🔧 Error Handling Improvements

Source Download

wget "${POOL_URL}ostree_${OSTREE_VERSION}-${OSTREE_DEBIAN_REVISION}.dsc" || exit 1
wget "${POOL_URL}ostree_${OSTREE_VERSION}.orig.tar.xz" || exit 1
wget "${POOL_URL}ostree_${OSTREE_VERSION}-${OSTREE_DEBIAN_REVISION}.debian.tar.xz" || exit 1

Build Process

dpkg-source -x "ostree_${OSTREE_VERSION}-${OSTREE_DEBIAN_REVISION}.dsc" || exit 1
apt-get build-dep -y --no-install-recommends ./ || exit 1
dpkg-buildpackage -us -uc -b || exit 1

Upload Statistics

upload_success=0
upload_failed=0
# ... upload logic ...
echo "Upload Summary for ${{ matrix.target_distro }}:"
echo "  ✅ Successful uploads: $upload_success"
echo "  ❌ Failed uploads: $upload_failed"

📈 Benefits

1. Reliability: Better error handling prevents silent failures
2. Flexibility: Support for single or multi-distribution builds
3. Debugging: Detailed logging for troubleshooting
4. Testing: Quick validation workflow for rapid iteration
5. Monitoring: Upload statistics and success tracking
6. Maintainability: Clear separation of concerns and configuration
