Commit 2: Gateway Refinements

Summary

Enhance Gateway process management with auto-reconnection, health checks, and improved state management for more robust WebSocket communication.

Changes

Electron Main Process

electron/gateway/manager.ts

• Added 'reconnecting' state to GatewayStatus
• Implemented ReconnectConfig with exponential backoff strategy
• Added maxAttempts, baseDelay, maxDelay configuration
• New methods:
  • isConnected() - Check WebSocket connection status
  • restart() - Stop and start Gateway
  • clearAllTimers() - Clean up timers on shutdown
  • startHealthCheck() - Periodic health monitoring
  • checkHealth() - Manual health check
• Enhanced handleMessage() to dispatch JSON-RPC responses and notifications
• Expanded GatewayManagerEvents for notification forwarding

electron/gateway/client.ts

• Extended with new interfaces: SkillBundle, CronTask, ProviderConfig
• Added cron task management methods:
  • listCronTasks(), createCronTask(), updateCronTask(), deleteCronTask(), runCronTask()
• Added provider management methods:
  • listProviders(), setProvider(), removeProvider(), testProvider()
• Enhanced system calls:
  • getHealth() now includes version
  • Added getVersion(), getSkillBundles(), installBundle()

electron/main/ipc-handlers.ts

• Added gateway:isConnected, gateway:health IPC handlers
• Added mainWindow.isDestroyed() checks before sending events
• Forward new gateway events: gateway:notification, gateway:channel-status, gateway:chat-message

electron/preload/index.ts

• Added new IPC channels for gateway operations
• Added notification event channels

React Renderer

src/stores/gateway.ts

• Added health: GatewayHealth | null, lastError: string | null to state
• Added checkHealth(), rpc(), clearError() actions
• Enhanced init() to listen for error and notification events

src/types/gateway.ts

• Added 'reconnecting' to GatewayStatus state enum
• Added version, reconnectAttempts fields
• New interfaces: GatewayHealth, GatewayNotification, ProviderConfig

src/components/common/StatusBadge.tsx

• Added 'reconnecting' status with warning variant

Technical Details

Reconnection Strategy

• Exponential backoff: delay = min(baseDelay * 2^attempt, maxDelay)
• Default: 1s base delay, 30s max delay, 10 max attempts
• Automatic reconnection on unexpected disconnection
• Manual control via shouldReconnect flag

Health Check

• Periodic ping/pong via JSON-RPC system.health
• Returns status, uptime, version information
• Triggers reconnection on consecutive failures
