Add two new configurable session settings to improve multi-session management:
1. Maximum Concurrent Sessions (1-20, default: 10)
- Controls the maximum number of simultaneous connections
- Configurable via settings UI with validation
- Applied in session manager during session creation
2. Observer Cleanup Timeout (30-600 seconds, default: 120)
- Automatically removes inactive observer sessions with closed RPC channels
- Prevents accumulation of zombie observer sessions
- Runs during periodic cleanup checks
- Configurable timeout displayed in minutes in UI
Backend changes:
- Add MaxSessions and ObserverTimeout fields to SessionSettings struct
- Update setSessionSettings RPC handler to persist new settings
- Implement observer cleanup logic in cleanupInactiveSessions
- Apply maxSessions limit in NewSessionManager with proper fallback chain
Frontend changes:
- Add numeric input controls for both settings in multi-session settings page
- Include validation and user-friendly error messages
- Display friendly units (sessions, seconds/minutes)
- Maintain consistent styling with existing settings
Also includes defensive nil checks in writeJSONRPCEvent to prevent
"No HDMI Signal" errors when RPC channels close during reconnection.
Improvements:
- Centralized permission state management in PermissionsProvider
- Eliminates duplicate RPC calls across components
- Single source of truth for permission state
- Automatic HID re-initialization on permission changes
- Split exports into separate files for React Fast Refresh compliance
- Created types/permissions.ts for Permission enum
- Created hooks/usePermissions.ts for the hook with safe defaults
- Created contexts/PermissionsContext.ts for context definition
- Updated PermissionsProvider.tsx to only export the provider component
- Removed redundant getSessionSettings RPC call (settings already in WebSocket/WebRTC messages)
- Added connectionModeChanged event handler for seamless emergency promotions
- Fixed approval dialog race condition by checking isLoadingPermissions
- Removed all redundant comments and code for leaner implementation
- Updated imports across 10+ component files
Result: Zero ESLint warnings, cleaner architecture, no duplicate RPC calls, all functionality preserved
Backend improvements:
- Keep denied sessions alive in pending mode instead of removing them
- Add requestSessionApproval RPC method for re-requesting access
- Fix security issue: preserve pending mode on reconnection for denied sessions
- Add MaxRejectionAttempts field to SessionSettings (default: 3, configurable 1-10)
Frontend improvements:
- Change "Try Again" button to "Request Access Again" that re-requests approval
- Add rejection counter with configurable maximum attempts
- Hide modal after max rejections; session stays pending in SessionPopover
- Add "Dismiss" button for primary to hide approval requests without deciding
- Add MaxRejectionAttempts control in multi-session settings page
- Reset rejection count when session is approved
This improves the user experience by allowing denied users to retry without
page reloads, while preventing spam with configurable rejection limits.
Address all linting warnings and errors in both backend and frontend code:
**Go (golangci-lint):**
- Add error checking for ignored return values (errcheck)
- Remove unused RPC functions (unused)
- Fix import formatting (goimports)
**TypeScript/React (eslint):**
- Replace all 'any' and 'Function' types with proper type definitions
- Add RpcSendFunction type for consistent JSON-RPC callback signatures
- Fix React Hook exhaustive-deps warnings by adding missing dependencies
- Wrap functions in useCallback where needed to stabilize dependencies
- Remove unused variables and imports
- Remove empty code blocks
- Suppress exhaustive-deps warnings where intentional (with comments)
All linting now passes with 0 errors and 0 warnings.
