Feature/background season data (#46)
* Fix NCAAFB ranking display issue - Remove duplicate ranking system that was drawing rankings behind team logos - Old system (_get_rank) was drawing rankings at top of logos - New system (_fetch_team_rankings) correctly draws rankings in bottom corners - Remove old ranking calls from live, recent, and upcoming game drawing functions - Remove unnecessary _fetch_rankings() calls from update methods - Rankings now only appear in designated corner positions, not overlapping logos Fixes issue where team rankings/betting lines were being drawn behind team logos instead of replacing team records in the corners. * Add missing show_ranking and show_records options to NCAAFB web UI - Add show_ranking option to NCAAFB scoreboard config template - Add show_records and show_ranking toggle switches to NCAAFB web UI - Update JavaScript form collection to include new fields - Users can now control whether to show team records or rankings via web interface This completes the fix for NCAAFB ranking display - users can now enable show_ranking in the web UI to see AP Top 25 rankings instead of team records. * Implement Background Threading for Season Data Fetching Phase 1: Background Season Data Fetching - COMPLETED Key Features: - Created BackgroundDataService class with thread-safe operations - Implemented automatic retry logic with exponential backoff - Modified NFL manager to use background service -

# Background Data Service for LEDMatrix
|
||||
|
||||
## Overview
|
||||
|
||||
The Background Data Service is a new feature that implements background threading for season data fetching to prevent blocking the main display loop. This significantly improves responsiveness and user experience during data fetching operations.
|
||||
|
||||
## Key Benefits
|
||||
|
||||
- **Non-blocking**: Season data fetching no longer blocks the main display loop
|
||||
- **Immediate Response**: Returns cached or partial data immediately while fetching complete data in background
|
||||
- **Configurable**: Can be enabled/disabled per sport with customizable settings
|
||||
- **Thread-safe**: Uses proper synchronization for concurrent access
|
||||
- **Retry Logic**: Automatic retry with exponential backoff for failed requests
|
||||
- **Progress Tracking**: Comprehensive logging and statistics
|
||||
|
||||
## Architecture
|
||||
|
||||
### Core Components
|
||||
|
||||
1. **BackgroundDataService**: Main service class managing background threads
|
||||
2. **FetchRequest**: Represents individual fetch operations
|
||||
3. **FetchResult**: Contains results of fetch operations
|
||||
4. **Sport Managers**: Updated to use background service
|
||||
|
||||
### How It Works
|
||||
|
||||
1. **Cache Check**: First checks for cached data and returns immediately if available
|
||||
2. **Background Fetch**: If no cache, starts background thread to fetch complete season data
|
||||
3. **Partial Data**: Returns immediate partial data (current/recent games) for quick display
|
||||
4. **Completion**: Background fetch completes and caches full dataset
|
||||
5. **Future Requests**: Subsequent requests use cached data for instant response
|
||||
|
||||
## Configuration
|
||||
|
||||
### NFL Configuration Example
|
||||
|
||||
```json
|
||||
{
|
||||
"nfl_scoreboard": {
|
||||
"enabled": true,
|
||||
"background_service": {
|
||||
"enabled": true,
|
||||
"max_workers": 3,
|
||||
"request_timeout": 30,
|
||||
"max_retries": 3,
|
||||
"priority": 2
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Configuration Options
|
||||
|
||||
- **enabled**: Enable/disable background service (default: true)
|
||||
- **max_workers**: Maximum number of background threads (default: 3)
|
||||
- **request_timeout**: HTTP request timeout in seconds (default: 30)
|
||||
- **max_retries**: Maximum retry attempts for failed requests (default: 3)
|
||||
- **priority**: Request priority (higher = more important, default: 2)
|
||||
|
||||
## Implementation Status
|
||||
|
||||
### Phase 1: Background Season Data Fetching ✅ COMPLETED
|
||||
|
||||
- [x] Created BackgroundDataService class
|
||||
- [x] Implemented thread-safe data caching
|
||||
- [x] Added retry logic with exponential backoff
|
||||
- [x] Modified NFL manager to use background service
|
||||
- [x] Added configuration support
|
||||
- [x] Created test script
|
||||
|
||||
### Phase 2: Rollout to Other Sports (Next Steps)
|
||||
|
||||
- [ ] Apply to NCAAFB manager
|
||||
- [ ] Apply to NBA manager
|
||||
- [ ] Apply to NHL manager
|
||||
- [ ] Apply to MLB manager
|
||||
- [ ] Apply to other sport managers
|
||||
|
||||
## Testing
|
||||
|
||||
### Test Script
|
||||
|
||||
Run the test script to verify background service functionality:
|
||||
|
||||
```bash
|
||||
python test_background_service.py
|
||||
```
|
||||
|
||||
### Test Scenarios
|
||||
|
||||
1. **Cache Hit**: Verify immediate return of cached data
|
||||
2. **Background Fetch**: Verify non-blocking background data fetching
|
||||
3. **Partial Data**: Verify immediate return of partial data during background fetch
|
||||
4. **Completion**: Verify background fetch completion and caching
|
||||
5. **Subsequent Requests**: Verify cache usage for subsequent requests
|
||||
6. **Service Disabled**: Verify fallback to synchronous fetching
|
||||
|
||||
### Expected Results
|
||||
|
||||
- Initial fetch should return partial data immediately (< 1 second)
|
||||
- Background fetch should complete within 10-30 seconds
|
||||
- Subsequent fetches should use cache (< 0.1 seconds)
|
||||
- No blocking of main display loop
|
||||
|
||||
## Performance Impact
|
||||
|
||||
### Before Background Service
|
||||
- Season data fetch: 10-30 seconds (blocking)
|
||||
- Display loop: Frozen during fetch
|
||||
- User experience: Poor responsiveness
|
||||
|
||||
### After Background Service
|
||||
- Initial response: < 1 second (partial data)
|
||||
- Background fetch: 10-30 seconds (non-blocking)
|
||||
- Display loop: Continues normally
|
||||
- User experience: Excellent responsiveness
|
||||
|
||||
## Monitoring
|
||||
|
||||
### Logs
|
||||
|
||||
The service provides comprehensive logging:
|
||||
|
||||
```
|
||||
[NFL] Background service enabled with 3 workers
|
||||
[NFL] Starting background fetch for 2024 season schedule...
|
||||
[NFL] Using 15 immediate events while background fetch completes
|
||||
[NFL] Background fetch completed for 2024: 256 events
|
||||
```
|
||||
|
||||
### Statistics
|
||||
|
||||
Access service statistics:
|
||||
|
||||
```python
|
||||
stats = background_service.get_statistics()
|
||||
print(f"Total requests: {stats['total_requests']}")
|
||||
print(f"Cache hits: {stats['cached_hits']}")
|
||||
print(f"Average fetch time: {stats['average_fetch_time']:.2f}s")
|
||||
```
|
||||
|
||||
## Error Handling
|
||||
|
||||
### Automatic Retry
|
||||
- Failed requests are automatically retried with exponential backoff
|
||||
- Maximum retry attempts are configurable
|
||||
- Failed requests are logged with error details
|
||||
|
||||
### Fallback Behavior
|
||||
- If background service is disabled, falls back to synchronous fetching
|
||||
- If background fetch fails, returns partial data if available
|
||||
- Graceful degradation ensures system continues to function
|
||||
|
||||
## Future Enhancements
|
||||
|
||||
### Phase 2 Features
|
||||
- Apply to all sport managers
|
||||
- Priority-based request queuing
|
||||
- Dynamic worker scaling
|
||||
- Request batching for efficiency
|
||||
|
||||
### Phase 3 Features
|
||||
- Real-time data streaming
|
||||
- WebSocket support for live updates
|
||||
- Advanced caching strategies
|
||||
- Performance analytics dashboard
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Common Issues
|
||||
|
||||
1. **Background service not starting**
|
||||
- Check configuration: `background_service.enabled = true`
|
||||
- Verify cache manager is properly initialized
|
||||
- Check logs for initialization errors
|
||||
|
||||
2. **Slow background fetches**
|
||||
- Increase `request_timeout` in configuration
|
||||
- Check network connectivity
|
||||
- Monitor API rate limits
|
||||
|
||||
3. **Memory usage**
|
||||
- Background service automatically cleans up old requests
|
||||
- Adjust `max_workers` if needed
|
||||
- Monitor cache size
|
||||
|
||||
### Debug Mode
|
||||
|
||||
Enable debug logging for detailed information:
|
||||
|
||||
```python
|
||||
logging.getLogger('src.background_data_service').setLevel(logging.DEBUG)
|
||||
```
|
||||
|
||||
## Contributing
|
||||
|
||||
When adding background service support to new sport managers:
|
||||
|
||||
1. Import the background service
|
||||
2. Initialize in `__init__` method
|
||||
3. Update data fetching method to use background service
|
||||
4. Add configuration options
|
||||
5. Test thoroughly
|
||||
6. Update documentation
