GitHub CI Workflow Improvements

Summary

Fixed both GitHub CI workflows (.github/workflows/ci.yml and .github/workflows/ci-full.yml) to use modern best practices and resolve several issues.

Issues Fixed

ci.yml (Basic CI)

Before:

• Used uv pip install --system which is not recommended in CI environments
• Ran tools directly instead of through uv run
• Used pip install uv instead of the official action
• Inconsistent Python version handling between jobs
• Missing error handling for coverage uploads

After:

• ✅ Uses astral-sh/setup-uv@v4 official action with caching
• ✅ Creates proper virtual environments with uv venv
• ✅ All tools run through uv run for consistency
• ✅ Proper error handling with fail_ci_if_error: false
• ✅ Optimized artifact uploads (only for Python 3.11)
• ✅ Better output formatting with --output-format=github for Ruff

ci-full.yml (Full CI with External Dependencies)

Before:

• Workflow was disabled (manual trigger only)
• Overcomplicated uv usage with unnecessary uv pip compile steps
• Hardcoded Python versions ("3.11.8")
• Redundant dependency installation steps

After:

• ✅ Enabled for automatic triggering on pushes and PRs
• ✅ Simplified uv usage - direct installation from requirements files
• ✅ Uses environment variables for Python version consistency
• ✅ Improved error handling for missing files
• ✅ Better structured with proper caching

Key Improvements

1. Modern uv Usage

# Before
- name: Install uv
  run: pip install uv
- name: Install dependencies
  run: |
    uv pip install --system -r requirements.txt

# After
- name: Install uv
  uses: astral-sh/setup-uv@v4
  with:
    version: "latest"
    enable-cache: true
- name: Create virtual environment and install dependencies
  run: |
    uv venv
    uv pip install -r requirements.txt

2. Consistent Tool Execution

# Before
run: ruff check .

# After
run: uv run ruff check . --output-format=github

3. Environment Variables

env:
  PYTHON_VERSION: "3.11"
  FORCE_COLOR: 1

4. Better Error Handling

- name: Upload coverage to Codecov
  uses: codecov/codecov-action@v4
  if: matrix.python-version == env.PYTHON_VERSION
  with:
    fail_ci_if_error: false

Workflow Structure

ci.yml (Basic)

• lint: Code quality checks (Ruff, Black, MyPy)
• test: Unit tests with PostgreSQL/Redis services
• security: Security scans (Bandit, Trivy)
• docker: Container builds on develop branch

ci-full.yml (Comprehensive)

• test: Full test suite with matrix strategy
• integration-tests: E2E and integration testing
• security: Enhanced security scanning with secrets detection
• deployment-prep: Validates deployment readiness
• pr-checks: Enforces PR title and branch naming conventions
• success: Final status check for all jobs

Benefits

1. Reliability: Proper virtual environment isolation
2. Performance: Caching enabled for uv and dependencies
3. Consistency: All tools run through uv run
4. Maintainability: Environment variables for version management
5. Visibility: Better error reporting and GitHub integration
6. Security: Enhanced security scanning and secrets detection

Recommendations

1. Required Secrets

Ensure these secrets are configured in your repository:

• CODECOV_TOKEN: For coverage reporting

2. Branch Protection

Configure branch protection rules to require:

• Status checks from both workflows
• PR reviews before merging
• Up-to-date branches

3. Additional Enhancements

Consider adding:

• Dependabot for dependency updates
• CodeQL analysis for security
• Performance regression testing
• Deployment automation for staging/production

4. Local Development

Ensure developers use the same tools locally:

# Install uv
curl -LsSf https://astral.sh/uv/install.sh | sh

# Create environment and install dependencies
uv venv
uv pip install -r requirements.txt -r requirements-dev.txt

# Run quality checks
uv run ruff check .
uv run black --check .
uv run mypy .
uv run pytest

Files Modified

• .github/workflows/ci.yml - Basic CI workflow
• .github/workflows/ci-full.yml - Full CI workflow with external dependencies

Next Steps

1. Test the workflows with a sample PR
2. Verify all required secrets are configured
3. Update documentation to reflect new CI requirements
4. Consider enabling automated deployments for successful builds
