- Add testDistributionUpdate() for backend data integration testing
- Add testSimulationFlow() for complete simulation monitoring
- Enhance testDistributionChart() with comprehensive diagnostics
- These functions help isolate the specific failure point for the wealth distribution histogram issue
- Can be called from browser console for production debugging
New Diagnostic Endpoints:
- /test-simulation: Full simulation flow testing
- /api/test-websocket: WebSocket connectivity testing
Enhanced Browser Testing:
- testWebSocket(): Test real-time communication
- testDistributionChart(): Enhanced chart diagnostics
- WebSocket test message handler for live testing
Debugging Improvements:
- Real-time WebSocket message testing
- Manual chart update testing
- Complete simulation data flow validation
- End-to-end connectivity verification
These tools will help identify the exact failure point
in the wealth distribution histogram issue.
Debugging Tools:
- Added /debug endpoint to verify deployment and test distribution functionality
- Added browser console test function: testDistributionChart()
- Enhanced SocketIO settings with better transport priorities
- Added comprehensive error tracking and status reporting
Nginx Configuration:
- Created NGINX_CONFIG.md with complete proxy setup guide
- Improved WebSocket transport settings and timeouts
- Better ping/pong settings for connection stability
Production Compatibility:
- Optimized SocketIO for proxy environments
- Enhanced fallback mechanisms
- Production-ready logging and error handling
This should resolve proxy-related issues and provide clear diagnostic tools.
Production Environment Fixes:
- Enhanced SocketIO configuration for proxy compatibility
- Added fallback polling mechanism when WebSocket fails
- Fixed environment configuration (FLASK_ENV vs FLASK_CONFIG)
- Added production-friendly debug logging for distribution chart
- Improved connection status monitoring and error handling
Proxy-Specific Improvements:
- Enhanced CORS and transport settings for SocketIO
- Fallback to HTTP polling when WebSocket connections fail
- Better error handling and retry mechanisms
- Debug logging that works in production mode
This should resolve the wealth distribution histogram issue
when running behind Nginx proxy in Docker containers.
- Removed __pycache__ directories from git tracking
- These files are now properly excluded by .gitignore
- Maintains repository cleanliness as per best practices
- Enhanced debug logging in simulation.js to track distribution data flow
- Improved data handling in updateCharts() with proper validation
- Added fallback mechanisms in onSimulationComplete() for distribution data
- Enhanced updateSimulationProgress() with better array copying
- Added comprehensive error handling and debug output
- Created .gitignore to exclude Python cache files
The histogram should now properly display wealth distribution data during simulations.
- Add get_wealth_histogram() method to EconomicModel for histogram data
- Add new API endpoint /simulation/<id>/distribution for chart data
- Extend main data API with include_distribution parameter
- Update real-time progress updates to include distribution data
- Fix frontend updateCharts() to handle wealth distribution chart
- Add distribution data processing in simulation.js
- Update test_charts.py to verify histogram functionality
Resolves issue where wealth distribution chart was not updating during simulations.
- Fix circular import issue by moving simulation_manager to app/__init__.py
- Enhance get_wealth_evolution to include inequality metrics data
- Add get_inequality_evolution method for complete chart data
- Update API to return top10_shares and capital_shares in evolution data
- Modify onSimulationComplete to fetch and populate charts with complete data
- Fix simulation threading to properly mark completion state
- Add test script to verify chart data generation
The charts now properly display simulation results by fetching complete
evolution data when simulation completes, resolving the empty diagrams issue.
- Add Dockerfile with multi-stage build for Flask app containerization
- Include .dockerignore to optimize build context
- Add docker-compose.yml for easy deployment with health checks
- Update run.py to handle production mode with allow_unsafe_werkzeug
- Add DOCKER.md with comprehensive deployment instructions
- Configure health check endpoint at /health
- Run as non-root user for security
- Support for environment variables and proper port mapping
