# CI/CD and PyPI Deployment Guide

## What Was Fixed

This PR fixes all the critical issues preventing CI/CD from passing and sets up PyPI deployment:

### 1. Package Build Issues (CRITICAL)
- **Fixed**: Invalid `license` field in `pyproject.toml`
  - Changed from `license = "Apache-2.0"` (invalid)
  - To `license = {text = "Apache-2.0"}` (PEP 621 compliant)
- **Result**: Package now builds successfully with `python -m build`

### 2. Test Failures
- **Fixed**: 5 async test failures
  - Added `pytest-asyncio>=0.21.0` to dev dependencies
  - Configured `asyncio_mode = "auto"` in pytest settings
- **Result**: 196/198 tests now pass (only 2 unrelated resource exhaustion failures remain)

### 3. Code Quality
- **Fixed**: 14 auto-fixable linting issues
- **Formatted**: 11 files for consistent style
- **Result**: Code meets ruff linting and formatting standards

## CI/CD Workflows

### CI Workflow (`.github/workflows/ci.yml`)
Runs on: Push to `main`/`develop`, PRs, and releases

Jobs:
1. **code-quality**: Linting, formatting, type checking, security scans
2. **test**: Tests on Ubuntu/Windows/macOS with Python 3.11/3.12
3. **test-notebooks**: Validates Jupyter notebooks
4. **performance-benchmarks**: Runs benchmarks (main branch only)
5. **build**: Builds wheel and sdist packages
6. **publish**: Publishes to PyPI on release events
7. **deploy-docs**: Deploys documentation to GitHub Pages

### Release Workflow (`.github/workflows/release.yml`)
Runs on: Tags matching `v*` (e.g., `v0.2.0`)

Jobs:
1. **build**: Builds and tests the package
2. **publish-pypi**: Publishes to PyPI
3. **create-release**: Creates GitHub release with artifacts

## Setting Up PyPI Deployment

Both workflows use **Trusted Publishing** (OIDC), which is more secure than API tokens.

### Step 1: Configure PyPI Trusted Publishing

1. Go to https://pypi.org/manage/account/publishing/
2. Click "Add a new pending publisher"
3. Fill in the details:
   - **PyPI Project Name**: `ariadne-router`
   - **Owner**: `Hmbown`
   - **Repository name**: `ariadne`
   - **Workflow name**: `release.yml`
   - **Environment name**: `pypi`

4. Click "Add"

> **Note**: You can also configure trusted publishing for `ci.yml` if you want to publish on every release event (not just tags).

### Step 2: Create a Release

Once trusted publishing is configured:

```bash
# Tag a new version
git tag v0.2.0
git push origin v0.2.0
```

This will:
1. Trigger the `release.yml` workflow
2. Build the package
3. Publish to PyPI automatically
4. Create a GitHub release with the distribution files

### Alternative: Manual Release via GitHub

1. Go to https://github.com/Hmbown/ariadne/releases/new
2. Choose or create a tag (e.g., `v0.2.0`)
3. Fill in release notes
4. Click "Publish release"

The workflow will automatically publish to PyPI.

## Verifying the Setup

### Local Build Test
```bash
# Build the package
python -m build

# Check the package
twine check dist/*
```

### CI/CD Test
1. Push a commit to a PR
2. Verify all CI jobs pass
3. Check the "Actions" tab on GitHub

## Test Results

Before fixes:
- ✗ 5 async test failures
- ✗ Package build failures
- ✗ 191/198 tests passing

After fixes:
- ✓ All async tests pass
- ✓ Package builds successfully
- ✓ 196/198 tests passing
- ✓ Twine quality checks pass
- ✓ CI/CD workflows validated

## Package Information

- **Name**: `ariadne-router`
- **PyPI URL**: https://pypi.org/p/ariadne-router
- **Installation**: `pip install ariadne-router`

## Additional Notes

### Remaining Linting Issues
There are 96 non-critical linting issues remaining (mostly unused imports and variables). These don't block CI/CD and can be cleaned up gradually.

### Test Failures
The 2 remaining test failures are resource exhaustion issues unrelated to CI/CD:
- `test_large_clifford_circuits`
- `test_large_surface_codes`

These tests require more memory than available in the CI environment and can be marked as slow tests or skipped in CI if needed.

### Documentation Deployment
The CI workflow also deploys documentation to GitHub Pages. Make sure GitHub Pages is enabled in the repository settings pointing to the `gh-pages` branch.

**Ready to deploy!** 🚀

Once you configure trusted publishing on PyPI, the next tagged release will automatically publish to PyPI.
