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.
- 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.
