…ates Updated documentation to reflect completed work in this session: ROADMAP.md: - Updated current version tracking (v1.3.0 in progress) - Added comprehensive v1.3.0 section documenting: - 143 diagnostics tests (~95% coverage) - Statistics recording integration - Remote server update system (11 API endpoints) - System Management GUI panel - Bug fixes and improvements - Listed all new API endpoints - Outlined v1.3.1 next steps README.md: - Enhanced diagnostics section with test coverage details - Added complete 'Remote server updates' feature section - Documented 11 system management API endpoints - Listed all update system capabilities: - Git-based updates - Automatic Docker rebuild - Scheduled update checks - Update notifications - Rollback capability - Real-time progress monitoring Both files now accurately reflect the ~4,500 lines of code added across diagnostics testing and remote server update features.
This commit includes major performance improvements and a comprehensive Raspberry Pi network discovery feature. Performance Optimizations: - Add 30-second TTL cache to diagnostics health checks to reduce lag - Implement AsyncWorker thread class for non-blocking GUI operations - Convert System Panel update checks to async operations with callbacks - Add cache invalidation on new diagnostic checks Raspberry Pi Discovery (Server-side): - Implement PiDiscovery class with network scanning capabilities - Add MAC address vendor prefix matching for Raspberry Pi identification - Implement hostname pattern matching (raspberry, raspberrypi, pi) - Create LabLink detection via HTTP endpoint probing (/api, /health, /api/system/version) - Add parallel host scanning with batching (20 hosts per batch) - Implement auto-network detection for CIDR ranges - Add ping-based host reachability checks with response time tracking Raspberry Pi Discovery (API): - Add POST /api/discovery/pi/scan endpoint for network scanning - Add GET /api/discovery/pi/status endpoint for cached results - Return detailed Pi information including IP, hostname, MAC, type, version, and response time Raspberry Pi Discovery (Client): - Add scan_raspberry_pis() and get_pi_discovery_status() API methods - Create comprehensive PiDiscoveryPanel GUI with scan controls - Implement color-coded table display (green for LabLink, orange for regular Pi) - Add double-click to connect to LabLink servers - Integrate Pi Discovery tab into main window - Support cached results display on panel load Files Changed: - server/diagnostics/manager.py: Add health check caching - server/discovery/pi_discovery.py: New Pi discovery module - server/discovery/__init__.py: Export Pi discovery classes - server/api/discovery.py: Add Pi scan API endpoints - client/api/client.py: Add Pi discovery API methods - client/ui/system_panel.py: Add AsyncWorker for non-blocking operations - client/ui/pi_discovery_panel.py: New Pi discovery GUI panel - client/ui/main_window.py: Integrate Pi Discovery panel Testing: - All features ready for integration testing - Network scanning optimized for typical home/lab networks (254 hosts) - GUI operations non-blocking to prevent interface lag
