Cross-platform CI pipeline

[Sstark97]

Phase 6: E2E and Polish

Create GitHub Actions workflow for cross-platform build, test, and AOT binary publishing.

Workflow File

.github/workflows/ci.yml

Jobs Required

1. Build and Test (Matrix)

Run on: macOS, Linux (Ubuntu), Windows

• .NET 10 SDK installation
• dotnet restore
• dotnet build --configuration Release
• dotnet test --no-build --verbosity normal
• Upload test results

2. Publish AOT Binaries (Matrix)

For each Runtime Identifier:

• osx-x64 (macOS Intel)
• osx-arm64 (macOS Apple Silicon)
• linux-x64 (Linux x64)
• linux-arm64 (Linux ARM64)
• win-x64 (Windows x64)
• win-arm64 (Windows ARM64)

Commands:

dotnet publish -c Release -r $RID \
  -p:PublishAot=true \
  -p:StripSymbols=true \
  -o ./publish/$RID

Artifact naming:

• devsweep-osx-x64
• devsweep-osx-arm64
• devsweep-linux-x64
• devsweep-linux-arm64
• devsweep-win-x64.exe
• devsweep-win-arm64.exe

3. E2E Tests (Post-Publish)

• Run smoke tests on each platform's published binary
• Verify binary size (~10-15MB target)
• Verify cold start time (<100ms)

4. Release (on tag)

When tag pushed (e.g., v2.0.0):

• Create GitHub release
• Upload all 6 AOT binaries as release assets
• Generate checksums (SHA256)
• Auto-generate release notes from conventional commits

CI Triggers

on:
  push:
    branches: [main, feature/*]
  pull_request:
    branches: [main]
  release:
    types: [published]

Quality Gates

• All tests must pass on all platforms
• Build must succeed on all platforms
• Code coverage report (coverlet)
• AOT compilation must succeed without warnings

Caching

• NuGet packages cache
• Restore cache across builds

Example Workflow Structure

name: CI

jobs:
  build-test:
    strategy:
      matrix:
        os: [ubuntu-latest, macos-latest, windows-latest]
    runs-on: ${{ matrix.os }}
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-dotnet@v4
        with:
          dotnet-version: '10.0.x'
      - run: dotnet test
      
  publish-aot:
    needs: build-test
    strategy:
      matrix:
        include:
          - os: macos-latest
            rid: osx-arm64
          - os: ubuntu-latest
            rid: linux-x64
          # ... more combinations
    # ...

Definition of Done

• CI workflow runs on all platforms
• All tests pass on macOS, Linux, Windows
• AOT binaries published for all 6 RIDs
• E2E tests run on published binaries
• Release automation working
• CI badge added to README
