## 🎨 Automatic Code Formatting

### Local Development
1. **VS Code Integration**: Auto-format on save with Black (line-length=100)
2. **Pre-commit Hooks**: Format before commits locally
3. **GitLab CI Validation**: `format_check` job blocks unformatted code

### GitLab CI Features
```yaml
# Fast feedback - runs in 'validate' stage before tests
format_check:
  stage: validate
  script:
    - black --check storm_logger/ tests/ --line-length=100 --diff --color
```

### Optional Auto-formatting Bot
```yaml
# Can be enabled to auto-fix formatting on develop branch
format_fix:
  stage: validate
  script:
    - black storm_logger/ tests/ --line-length=100
    - git commit -m "🎨 Auto-format code with Black [skip ci]"
  rules:
    - if: $AUTO_FORMAT_ENABLED == "true"
```

## 🔄 Merge Request Automation

### MR Templates
Located in `.gitlab/merge_request_templates/Default.md`:
- Automatic checklist for code quality
- Coverage requirements reminder
- Review requirements section
- Links to related issues

### MR-Specific CI Jobs

#### 1. **Format Bot** (`mr_format_bot`)
- Comments on MR if formatting is needed
- Provides exact commands to fix
- Blocks merge until fixed

#### 2. **Code Review Assistant** (`mr_review_assistant`)
- Runs Pylint, Flake8, Vulture
- Posts summary comment with:
  - Issue counts by type
  - Dead code detection
  - Complexity warnings

#### 3. **MR Size Check** (`mr_size_check`)
- Auto-labels MRs by size (XS, S, M, L, XL)
- Warns if MR is too large
- Helps maintain small, reviewable changes

### Code Owners (CODEOWNERS)
- Automatic review assignments
- Required approvals for critical paths
- Different teams for different components:
  - Core: `@mathew @senior-architect`
  - Security: `@security-team`
  - Django: `@django-team`

## 🔒 Code Quality & Security

### GitLab Native Integration
```yaml
# GitLab Code Quality Report
code_quality_gitlab:
  stage: analyze
  artifacts:
    reports:
      codequality: gl-code-quality-report.json
```

### Security Scanning
1. **Dependency Scanning**: Built-in GitLab feature
2. **License Compliance**: Automatic license checking
3. **Secret Detection**: Prevents accidental secret commits
4. **SAST**: Static security analysis

### Complexity Analysis
```yaml
complexity_analysis:
  stage: analyze
  script:
    - radon cc storm_logger/ -a -nb
    - xenon storm_logger/ --max-absolute B
```

## 🛡️ Push Rules & Branch Protection

### Push Rules Configuration
Located in `.gitlab/push-rules.yml`:

#### Commit Message Format
```regex
^(feat|fix|docs|style|refactor|test|chore)(\(.+\))?: .{1,50}
```

#### Branch Naming Convention
```regex
^(main|develop|feature\/[a-z0-9-]+|bugfix\/[a-z0-9-]+)$
```

#### File Restrictions
- Blocked: `*.pyc`, `__pycache__/`, `.env`, secrets
- Required: `README.md`, `pyproject.toml`, `.gitlab-ci.yml`
- Max file size: 10MB

### Protected Branches
- **main**: Requires maintainer approval + code owner
- **develop**: Developer can merge, maintainer to unprotect

## 🚀 GitLab-Specific CI/CD Features

### Multi-Stage Pipeline
```yaml
stages:
  - validate     # Quick checks (formatting, linting)
  - test        # Full test suite
  - analyze     # Code quality, security
  - build       # Package creation
  - deploy      # PyPI deployment
```

### Advanced Caching
```yaml
cache:
  key:
    files:
      - setup.py
      - requirements.txt
  paths:
    - .cache/pip/
    - .venv/
```

### Parallel Testing
```yaml
test_python_versions:
  parallel:
    matrix:
      - PYTHON_VERSION: ["3.10", "3.11", "3.12"]
```

### GitLab Pages Integration
- Automatic test report hosting
- Coverage badges
- Performance benchmarks
- Security reports

## 🛠️ Developer Productivity Tools

### 1. **Issue Templates**

- Feature Request template
- Auto-labeling based on template

### 2. **Environments**
```yaml
environment:
  name: pypi-production
  url: https://pypi.org/project/storm-logger/
```

### 3. **CI/CD Variables**
```yaml
variables:
  SECURE_ANALYZERS_PREFIX: "registry.gitlab.com/security-products"
  DS_EXCLUDED_PATHS: "tests/,venv/,htmlcov/"
```

### 4. **Review Apps** (Optional)
Can deploy feature branches for testing

### 5. **GitLab Package Registry**
Can publish to GitLab's package registry in addition to PyPI
