**Goal**: Wire sandbox into existing kernel.
|
||||
**Estimated Files**: Modify existing files
|
||||
**Status**: Complete
|
||||
**Goal**: Multi-app sandbox orchestrator for kernel integration.
|
||||
|

### Deliverables
|
||||
|
||||
| Component | File | Description |
|
||||
|-----------|------|-------------|
|
||||
| App lifecycle | `src/main/cpp/kernel.cpp` | App start/stop |
|
||||
| Sandbox manager | `src/main/cpp/kernel.cpp` | Multi-app management |
|
||||
| LuaSandboxManager | `src/main/cpp/sandbox/sandbox_manager.h` | Multi-app orchestrator |
|
||||
| Implementation | `src/main/cpp/sandbox/sandbox_manager.cpp` | App lifecycle management |
|
||||
| AppSandbox struct | `src/main/cpp/sandbox/sandbox_manager.h` | Per-app component container |
|
||||
|
||||
### Implementation Tasks
|
||||
|
||||
1. Replace global `lua_State` with `LuaSandboxManager`:
|
||||
- Create sandbox per app
|
||||
- Route events to correct sandbox
|
||||
1. ✅ Create `LuaSandboxManager` class:
|
||||
- Multi-app management with Start/Stop lifecycle
|
||||
- Shared components (AuditLog, RateLimiter, MessageBus, TimerManager)
|
||||
- Thread-safe app map access
|
||||
|
||||
2. Integrate with RmlUi:
|
||||
- Bridge RmlUi document events to sandbox
|
||||
- Replace `Rml::Lua::Interpreter` with sandboxed states
|
||||
2. ✅ Create `AppSandbox` struct:
|
||||
- Per-app isolated Lua state and permissions
|
||||
- Per-app VirtualFS, DatabaseManager, NetworkManager
|
||||
- Per-app hardware interfaces (camera, mic, audio, location, sensors, bluetooth, contacts)
|
||||
|
||||
3. Wire up resource cleanup on app stop.
|
||||
3. ✅ Wire up resource cleanup on app stop:
|
||||
- Clear timers, close websockets, shutdown hardware
|
||||
- Clean temp files, close databases, unregister from message bus

||||

# Milestone 20: Kernel Integration
|
||||
|
||||
**Status**: Complete
|
||||
**Goal**: Multi-app sandbox orchestrator for kernel integration.
|
||||
|

|
||||
|
||||
## Overview
|
||||
|
||||
This milestone creates the LuaSandboxManager class that orchestrates multiple isolated Lua app sandboxes, providing the final integration point for the kernel.
|
||||
|
||||
### Key Deliverables
|
||||
|
||||
1. **LuaSandboxManager class** - Manages multiple concurrent app sandboxes
|
||||
2. **AppSandbox struct** - Per-app container with all components
|
||||
3. **Lifecycle management** - Start/stop apps with full resource cleanup
|
||||
4. **Shared components** - Cross-app services (AuditLog, RateLimiter, MessageBus, TimerManager)

|
||||
## Implementation Details
|
||||
|
||||
### 1. AppSandbox Struct
|
||||
|
||||
Per-app container holding all isolated components:
|
||||
|
||||
```cpp
|
||||
struct AppSandbox {
|
||||
std::unique_ptr<LuaSandbox> lua;
|
||||
std::unique_ptr<PermissionGate> permissions;
|
||||
std::unique_ptr<VirtualFS> filesystem;
|
||||
std::unique_ptr<DatabaseManager> database;
|
||||
std::unique_ptr<NetworkManager> network;
|
||||
std::unique_ptr<WebSocketManager> websocket;
|
||||
std::unique_ptr<CameraInterface> camera;
|
||||
std::unique_ptr<MicrophoneInterface> microphone;
|
||||
std::unique_ptr<AudioOutputInterface> audio;
|
||||
std::unique_ptr<LocationInterface> location;
|
||||
std::unique_ptr<SensorInterface> sensors;
|
||||
std::unique_ptr<BluetoothInterface> bluetooth;
|
||||
std::unique_ptr<ContactsInterface> contacts;
|
||||
SandboxContext context;
|
||||
bool is_running = false;
|
||||
};
|
||||
```
|
||||
|
||||
### 2. LuaSandboxManager Class
|
||||
|
||||
```cpp
|
||||
class LuaSandboxManager {
|
||||
public:
|
||||
explicit LuaSandboxManager(const std::string& data_root = ".");
|
||||
~LuaSandboxManager();
|
||||
|
||||
// App lifecycle
|
||||
bool StartApp(const std::string& app_id, const std::string& app_path,
|
||||
const std::vector<std::string>& permissions,
|
||||
bool is_system_app = false);
|
||||
bool StopApp(const std::string& app_id);
|
||||
bool IsAppRunning(const std::string& app_id) const;
|
||||
|
||||
// Get app sandbox for direct access
|
||||
AppSandbox* GetApp(const std::string& app_id);
|
||||
const AppSandbox* GetApp(const std::string& app_id) const;
|
||||
|
||||
// Execute Lua code in app context
|
||||
bool ExecuteCode(const std::string& app_id, const std::string& code,
|
||||
const std::string& source_name = "script");
|
||||
bool LoadFile(const std::string& app_id, const std::string& path);
|
||||
|
||||
// User gesture tracking
|
||||
void RecordUserGesture(const std::string& app_id);
|
||||
|
||||
// Timer management
|
||||
void UpdateTimers();
|
||||
|
||||
// Get all running app IDs
|
||||
std::vector<std::string> GetRunningApps() const;
|
||||
size_t GetRunningAppCount() const;
|
||||
|
||||
// Shared components
|
||||
AuditLog& GetAuditLog();
|
||||
RateLimiter& GetRateLimiter();
|
||||
MessageBus& GetMessageBus();
|
||||
TimerManager& GetTimerManager();
|
||||
|
||||
// Configuration
|
||||
void SetDefaultLimits(const SandboxLimits& limits);
|
||||
const SandboxLimits& GetDefaultLimits() const;
|
||||
};
|
||||
```
|
||||
|
||||
### 3. App Lifecycle
|
||||
|
||||
**StartApp Flow:**
|
||||
1. Create SandboxContext from parameters
|
||||
2. Create AppSandbox with all components
|
||||
3. Register JSON and Crypto APIs
|
||||
4. Store manager/app references in Lua registry
|
||||
5. Mark as running and store in map
|
||||
|
||||
**StopApp Flow:**
|
||||
1. Clear app timers
|
||||
2. Close WebSocket connections
|
||||
3. Shutdown camera/microphone/audio
|
||||
4. Shutdown location/sensors/bluetooth
|
||||
5. Clear temp files in VirtualFS
|
||||
6. Close database connections
|
||||
7. Unregister from message bus
|
||||
8. Remove from map
|
||||
|
||||
### 4. Resource Isolation
|
||||
|
||||
Each app gets:
|
||||
- Isolated Lua state
|
||||
- Isolated permissions
|
||||
- Isolated filesystem (under `data_root/apps/{app_id}/`)
|
||||
- Isolated database directory
|
||||
- Isolated network manager
|
||||
- Isolated hardware interfaces
|
||||
|
||||
Shared across apps:
|
||||
- AuditLog (thread-safe)
|
||||
- RateLimiter (app-keyed)
|
||||
- MessageBus (for inter-app communication)
|
||||
- TimerManager (timers keyed by app_id)
|
||||

## Notes
|
||||
|
||||
### Thread Safety
|
||||
|
||||
LuaSandboxManager is thread-safe via mutex protection on all public methods that access the app map.
|
||||
|
||||
### Memory Management
|
||||
|
||||
All components use unique_ptr for automatic cleanup. When StopApp is called:
|
||||
1. CleanupApp() releases resources gracefully
|
||||
2. unique_ptr destructors clean up remaining state
|
||||
3. App is removed from map
|
||||
|
||||
### Integration with Kernel
|
||||
|
||||
The kernel can integrate with LuaSandboxManager by:
|
||||
1. Creating a single manager instance at startup
|
||||
2. Calling StartApp() for each installed app
|
||||
3. Calling UpdateTimers() from the main loop
|
||||
4. Calling RecordUserGesture() on UI interactions
|
||||
5. Using GetApp() to access specific app components
|
||||
6. Calling StopApp() when apps are closed
|
||||
