# ivatar/libravatar Project Rules
## Project Overview
ivatar is a Django-based federated avatar service that serves as an alternative to Gravatar. It provides avatar images for email addresses and OpenID URLs, with support for the Libravatar federation protocol.
## Core Functionality
- Avatar service for email addresses and OpenID URLs
- Federated compatibility with Libravatar protocol
- Multiple authentication methods (OpenID, OpenID Connect/Fedora, Django auth)
- Image upload, cropping, and management
- External avatar import (Gravatar, other Libravatar instances)
- Bluesky handle integration
- Multiple theme support (default, clime, green, red)
- Internationalization (15+ languages)
## Technical Stack
- **Framework**: Django 4.2+ with Python 3.x
- **Database**: SQLite (development), MySQL/MariaDB, PostgreSQL (production)
- **Image Processing**: PIL/Pillow for image manipulation
- **Authentication**: django-openid-auth, social-auth-app-django
- **Caching**: Memcached and filesystem caching
- **Email**: Mailgun integration via django-anymail
- **Testing**: pytest with custom markers
## Key Models
- `Photo`: Stores uploaded avatar images with format detection and access counting
- `ConfirmedEmail`: Verified email addresses with assigned photos and Bluesky handles
- `ConfirmedOpenId`: Verified OpenID URLs with assigned photos and Bluesky handles
- `UserPreference`: User theme preferences
- `UnconfirmedEmail`: Email verification workflow
- `UnconfirmedOpenId`: OpenID verification workflow
## Security Features
- File upload validation and sanitization
- EXIF data removal (ENABLE_EXIF_SANITIZATION)
- Malicious content scanning (ENABLE_MALICIOUS_CONTENT_SCAN)
- Comprehensive security logging
- File size limits and format validation
- Trusted URL validation for external avatar sources
## Development Workflow Rules
### External Resources & Libraries
- **Web search is always allowed** - use web search to find solutions, check documentation, verify best practices
- **Use latest library versions** - always prefer the latest stable versions of external libraries
- **Security first** - outdated libraries are security risks, always update to latest versions
- **Dependency management** - when adding new dependencies, ensure they're actively maintained and secure
### Testing
- **MANDATORY: Run pre-commit hooks and tests before any changes** - this is an obligation
- Use `./run_tests_local.sh` for local development (skips Bluesky tests requiring API credentials)
- Run `python3 manage.py test -v3` for full test suite including Bluesky tests
- **MANDATORY: When adding new code, always write tests to increase code coverage** - never decrease coverage
- Use pytest markers appropriately:
- `@pytest.mark.bluesky`: Tests requiring Bluesky API credentials
- `@pytest.mark.slow`: Long-running tests
- `@pytest.mark.integration`: Integration tests
- `@pytest.mark.unit`: Unit tests
### Code Quality
- Always check for linter errors after making changes using `read_lints`
- Follow existing code style and patterns
- Maintain comprehensive logging (use `logger = logging.getLogger("ivatar")`)
- Consider security implications of any changes
- Follow Django best practices and conventions
- **Reduce script creation** - avoid creating unnecessary scripts, prefer existing tools and commands
- **Use latest libraries** - always use the latest versions of external libraries to ensure security and bug fixes
### Database Operations
- Use migrations for schema changes: `./manage.py migrate`
- Support multiple database backends (SQLite, MySQL, PostgreSQL)
- Use proper indexing for performance (see existing model indexes)
### Image Processing
- Support multiple formats: JPEG, PNG, GIF, WEBP
- Maximum image size: 512x512 pixels (AVATAR_MAX_SIZE)
- Maximum file size: 10MB (MAX_PHOTO_SIZE)
- JPEG quality: 85 (JPEG_QUALITY)
- Always validate image format and dimensions
## Configuration Management
- Main settings in `ivatar/settings.py` and `config.py`
- Local overrides in `config_local.py` (not in version control)
- Environment variables for sensitive data (database credentials, API keys)
- Support for multiple deployment environments (development, staging, production)
## Authentication & Authorization
- Multiple backends: Django auth, OpenID, Fedora OIDC
- Social auth pipeline with custom steps for email confirmation
- User account creation and management
- Email verification workflow
## Caching Strategy
- Memcached for general caching
- Filesystem cache for generated images
- 5-minute cache for resized images (CACHE_IMAGES_MAX_AGE)
- Cache invalidation on photo updates
## Internationalization
- Support for 15+ languages
- Use Django's translation framework
- Template strings should be translatable
- Locale-specific formatting
## File Structure Guidelines
- Main Django app: `ivatar/`
- Account management: `ivatar/ivataraccount/`
- Tools: `ivatar/tools/`
- Static files: `ivatar/static/` and `static/`
- Templates: `templates/` and app-specific template directories
- Tests: Co-located with modules or in dedicated test files
## Security Considerations
- Always validate file uploads
- Sanitize EXIF data from images
- Use secure password hashing (Argon2 preferred, PBKDF2 fallback)
- Implement proper CSRF protection
- Use secure cookies in production
- Log security events to dedicated security log
## Performance Considerations
- Use database indexes for frequently queried fields
- Implement proper caching strategies
- Optimize image processing operations
- Monitor access counts for analytics
- Use efficient database queries
## Production Deployment & Infrastructure
### Hosting & Sponsorship
- **Hosted by Fedora Project** - Free infrastructure provided due to heavy usage by Fedora community
- **Scale**: Handles millions of requests daily for 30k+ users with 33k+ avatar images
- **Performance**: High-performance system optimized for dynamic content (CDN difficult due to dynamic sizing)
### Production Architecture
- **Redis**: Session storage (potential future caching expansion)
- **Monitoring Stack**:
- Prometheus + Alertmanager for metrics and alerting
- Loki for log aggregation
- Alloy for observability
- Grafana for visualization
- Custom exporters for application metrics
- **Apache HTTPD**:
- SSL termination
- Load balancer for Gunicorn containers
- Caching (memory/socache and disk cache - optimization ongoing)
- **PostgreSQL**: Main production database
- **Gunicorn**: 2 containers running Django application
- **Containerization**: **Podman** (not Docker) - always prefer podman when possible
### Development Environment
- **Dev Instance**: dev.libravatar.org (auto-deployed from 'devel' branch via Puppet)
- **Limitation**: Aging CentOS 7 host with older Python 3.x and Django versions
- **Compatibility**: Must maintain backward compatibility with older versions
### CI/CD & Version Control
- **GitLab**: Self-hosted OSS/Community Edition on git.linux-kernel.at
- **CI**: GitLab CI extensively used
- **CD**: GitLab CD on roadmap (part of libravatar-ansible project)
- **Deployment**: Separate libravatar-ansible project handles production deployments
- **Container Management**: Ansible playbooks rebuild custom images and restart containers as needed
### Deployment Considerations
- Production requires proper database setup (PostgreSQL, not SQLite)
- Static file collection required: `./manage.py collectstatic`
- Environment-specific configuration via environment variables
- Custom container images with automated rebuilds
- High availability and performance optimization critical
## Common Commands
```bash
# Development server
./manage.py runserver 0:8080
# Run local tests (recommended for development)
./run_tests_local.sh
# Run all tests
python3 manage.py test -v2
# Database migrations
./manage.py migrate
# Collect static files
./manage.py collectstatic -l --no-input
# Create superuser
./manage.py createsuperuser
```
## Code Style Guidelines
- Use descriptive variable and function names
- Add comprehensive docstrings for classes and methods
- **MANDATORY: Include type hints for ALL new code** - this is a strict requirement
- Follow PEP 8 and Django coding standards
- Use meaningful commit messages
- Add comments for complex business logic
## Error Handling
- Use proper exception handling with specific exception types
- Log errors with appropriate levels (DEBUG, INFO, WARNING, ERROR)
- Provide user-friendly error messages
- Implement graceful fallbacks where possible
## API Compatibility
- Maintain backward compatibility with existing avatar URLs
- Support Libravatar federation protocol
- Ensure Gravatar compatibility for imports
- Preserve existing URL patterns and parameters
## Monitoring & Logging
- Use structured logging with appropriate levels
- Log security events to dedicated security log
- Monitor performance metrics (access counts, response times)
- Implement health checks for external dependencies
- **Robust logging setup**: Automatically tests directory writeability and falls back gracefully
- **Fallback hierarchy**: logs/ → /tmp/libravatar-logs → user-specific temp directory
- **Permission handling**: Handles cases where logs directory exists but isn't writable
## GitLab CI/CD Monitoring
- **MANDATORY: Check GitLab pipeline status regularly** during development
- Monitor pipeline status for the current working branch (typically `devel`)
- Use `glab ci list --repo git.linux-kernel.at/oliver/ivatar --per-page 5` to check recent pipelines
- Verify all tests pass before considering work complete
- Check pipeline logs with `glab ci trace <pipeline-id> --repo git.linux-kernel.at/oliver/ivatar` if needed
- Address any CI failures immediately before proceeding with new changes
- Pipeline URL: https://git.linux-kernel.at/oliver/ivatar/-/pipelines
## Deployment Verification
- **Automatic verification**: GitLab CI automatically verifies dev.libravatar.org deployments on `devel` branch
- **Manual verification**: Production deployments on `master` branch can be verified manually via CI
- **Version endpoint**: `/deployment/version/` provides commit hash, branch, and deployment status
- **Security**: Version endpoint uses cached git file reading (no subprocess calls) to prevent DDoS attacks
- **Performance**: Version information is cached in memory to avoid repeated file system access
- **SELinux compatibility**: No subprocess calls that might be blocked by SELinux policies
- **Manual testing**: Use `./scripts/test_deployment.sh` to test deployments locally
- **Deployment timing**: Dev deployments via Puppet may take up to 30 minutes to complete
- **Verification includes**: Version matching, avatar endpoint, stats endpoint functionality
Remember: This is a production avatar service handling user data and images. Security, performance, and reliability are paramount. Always consider the impact of changes on existing users and federated services.

# File Upload Security Documentation
## Overview
The ivatar application now includes comprehensive file upload security features to protect against malicious file uploads, data leaks, and other security threats.
## Security Features
### 1. File Type Validation
**Magic Bytes Verification**
- Validates file signatures (magic bytes) to ensure uploaded files are actually images
- Supports JPEG, PNG, GIF, WebP, BMP, and TIFF formats
- Prevents file extension spoofing attacks
**MIME Type Validation**
- Uses python-magic library to detect actual MIME types
- Cross-references with allowed MIME types list
- Prevents MIME type confusion attacks
### 2. Content Security Scanning
**Malicious Content Detection**
- Scans for embedded scripts (`<script>`, `javascript:`, `vbscript:`)
- Detects executable content (PE headers, ELF headers)
- Identifies polyglot attacks (files valid in multiple formats)
- Checks for PHP and other server-side code
**PIL Image Validation**
- Uses Python Imaging Library to verify file is a valid image
- Checks image dimensions and format
- Ensures image can be properly loaded and processed
### 3. EXIF Data Sanitization
**Metadata Removal**
- Automatically strips EXIF data from uploaded images
- Prevents location data and other sensitive metadata leaks
- Preserves image quality while removing privacy risks
### 4. Enhanced Logging
**Security Event Logging**
- Logs all file upload attempts with user ID and IP address
- Records security violations and suspicious activity
- Provides audit trail for security monitoring
## Configuration
### Settings
All security features can be configured in `config.py` or overridden in `config_local.py`:
```python
# File upload security settings
ENABLE_FILE_SECURITY_VALIDATION = True
ENABLE_EXIF_SANITIZATION = True
ENABLE_MALICIOUS_CONTENT_SCAN = True
```
### Dependencies
The security features require the following Python packages:
```bash
pip install python-magic>=0.4.27
```
**Note**: On some systems, you may need to install the libmagic system library:
- **Ubuntu/Debian**: `sudo apt-get install libmagic1`
- **CentOS/RHEL**: `sudo yum install file-devel`
- **macOS**: `brew install libmagic`
## Security Levels
### Security Score System
Files are assigned a security score (0-100) based on validation results:
- **90-100**: Excellent - No security concerns
- **80-89**: Good - Minor warnings, safe to process
- **70-79**: Fair - Some concerns, review recommended
- **50-69**: Poor - Multiple issues, high risk
- **0-49**: Critical - Malicious content detected, reject
### Validation Levels
1. **Basic Validation**: File size, filename, extension
2. **Magic Bytes**: File signature verification
3. **MIME Type**: Content type validation
4. **PIL Validation**: Image format verification
5. **Security Scan**: Malicious content detection
6. **EXIF Sanitization**: Metadata removal
## API Reference
### FileValidator Class
```python
from ivatar.file_security import FileValidator
validator = FileValidator(file_data, filename)
results = validator.comprehensive_validation()
```
### Main Validation Function
```python
from ivatar.file_security import validate_uploaded_file
is_valid, results, sanitized_data = validate_uploaded_file(file_data, filename)
```
### Security Report Generation
```python
from ivatar.file_security import get_file_security_report
report = get_file_security_report(file_data, filename)
```
## Error Handling
### Validation Errors
The system provides user-friendly error messages while logging detailed security information:
- **Malicious Content**: "File appears to be malicious and cannot be uploaded"
- **Invalid Format**: "File format not supported or file appears to be corrupted"
### Logging Levels
- **INFO**: Successful uploads and normal operations
- **WARNING**: Security violations and suspicious activity
- **ERROR**: Validation failures and system errors
## Testing
### Running Security Tests
```bash
python manage.py test ivatar.test_file_security
```
### Test Coverage
The test suite covers:
- Valid file validation
- Malicious content detection
- Magic bytes verification
- MIME type validation
- EXIF sanitization
- Form validation
- Integration tests
## Performance Considerations
### Memory Usage
- Files are processed in memory for validation
- Large files (>5MB) may impact performance
- Consider increasing server memory for high-volume deployments
### Processing Time
- Basic validation: <10ms
- Full security scan: 50-200ms
- EXIF sanitization: 100-500ms
- Total overhead: ~200-700ms per upload
## Troubleshooting
### Common Issues
1. **python-magic Import Error**
- Install libmagic system library
- Verify python-magic installation
2. **False Positives**
- Review security score thresholds
- Adjust validation settings
### Debug Mode
Enable debug logging to troubleshoot validation issues:
```python
LOGGING = {
"loggers": {
"ivatar.security": {
"level": "DEBUG",
},
},
}
```
## Security Best Practices
### Deployment Recommendations
1. **Enable All Security Features** in production
2. **Monitor Security Logs** regularly
3. **Keep Dependencies Updated**
4. **Regular Security Audits** of uploaded content
### Monitoring
- Monitor security.log for violations
- Track upload success/failure rates
- Alert on repeated security violations
## Future Enhancements
Potential future improvements:
- Virus scanning integration (ClamAV)
- Content-based image analysis
- Machine learning threat detection
- Advanced polyglot detection
- Real-time threat intelligence feeds

## Architecture
### Components
1. **OpenTelemetry Configuration** (`ivatar/opentelemetry_config.py`)
- Centralized configuration management
- Environment-based setup
- Resource creation with service metadata
2. **Custom Middleware** (`ivatar/opentelemetry_middleware.py`)
- Request/response tracing
- Avatar-specific metrics
- Custom decorators for operation tracing
3. **Instrumentation Integration**
- Django framework instrumentation
- Database query tracing (PostgreSQL/MySQL)
- HTTP client instrumentation
- Cache instrumentation (Memcached)

## Troubleshooting
### Common Issues
#### OpenTelemetry Not Enabled
- Check `OTEL_ENABLED` environment variable
- Verify OpenTelemetry packages are installed
- Check Django logs for configuration errors
#### Metrics Not Appearing
- Verify Prometheus endpoint is accessible
- Check collector configuration
- Ensure metrics are being generated
#### Traces Not Showing
- Verify OTLP endpoint configuration
- Check collector connectivity
- Ensure tracing is enabled in configuration
#### High Memory Usage
- Adjust batch processor settings
- Reduce trace sampling rate
- Monitor collector resource usage
### Debug Mode
Enable debug logging for OpenTelemetry:
```python
LOGGING = {
"loggers": {
"opentelemetry": {
"level": "DEBUG",
},
"ivatar.opentelemetry": {
"level": "DEBUG",
},
},
}
```
### Performance Considerations
- **Sampling**: Implement trace sampling for high-traffic production
- **Batch Processing**: Use appropriate batch sizes for your infrastructure
- **Resource Limits**: Monitor collector resource usage
