Module WindAdvancedSync

Expand description

Wind UI framework synchronization.

§Wind Advanced Synchronization - Real-time Document & UI Sync

File Responsibilities: This module implements advanced synchronization features that keep Wind’s frontend state in sync with Mountain’s backend state in real-time. It handles document changes, UI state updates, and broadcast updates across the editor ecosystem.

Architectural Role in Wind-Mountain Connection:

The WindAdvancedSync module is responsible for:

Document Synchronization: Real-time tracking and synchronization of document changes between Wind (frontend editor) and Mountain (backend services)
UI State Sync: Synchronizing UI state across multiple editor windows
- Cursor positions
- Selection ranges
- Zoom levels
- Theme and layout
Real-time Broadcasting: Broadcasting updates to interested subscribers
Conflict Detection: Identifying and handling conflicting changes
Performance Tracking: Monitoring sync performance and health

Synchronization Architecture:

Three Sync Layers:

1. Document Synchronization (Every 5 seconds):

Wind Editor (User Edits)
    |
    | Detect changes
    v
WindAdvancedSync
    |
    | Check for conflicts
    v
Mountain Services
    |
    | Apply changes
    v
File System / Storage

2. UI State Synchronization (Every 1 second):

Wind UI Window
    |
    | Capture state (cursor, selection, zoom)
    v
WindAdvancedSync
    |
    | Update internal state
    v
Apply to other windows

3. Real-time Updates (Every 100ms):

Subscribed Listeners
    ^
    | Broadcast updates
    |
WindAdvancedSync
    |
    | Queue updates
    v
Update Queue

Document Synchronization States:

enum SyncState {
	Modified,   // Changed locally, not synced
	Synced,     // Successfully synchronized
	Conflicted, // Conflicts need resolution
	Offline,    // Cannot sync (offline)
}

Change Types Supported:

enum ChangeType {
	Update, // File content updated
	Insert, // New file created
	Delete, // File deleted
	Move,   // File moved/renamed
	Other,  // Other changes
}

Conflict Detection (Microsoft-Inspired):

Detection Criteria:

Document modified recently (within 10 seconds of last sync)
Document is already in conflicted state
Multiple simultaneous changes detected

Conflict Response:

return Err(format!(
	"Conflict detected: Document {} was modified recently ({}s ago)",
	document_id,
	current_time - document.last_modified
));

Error Recovery (Circuit Breaker Pattern):

Circuit Breaker States:

Closed (Normal): Operations proceed normally
Open (Degraded): Too many failures, slow down sync interval
Half-Open (Testing): Slowly testing if system recovered

Recovery Logic:

Track consecutive failures (max 3)
On reaching limit: Increase sync interval to 30s
On success: Reset interval to 5s
Provides protection against cascading failures

Trackable Metrics:

Sync.Status:

SyncStatus {
	total_documents:u32,       // All tracked documents
	synced_documents:u32,      // Successfully synced
	conflicted_documents:u32,  // Have conflicts
	offline_documents:u32,     // Cannot sync
	last_sync_duration_ms:u64, // Time for last sync
}

UI State Tracked:

UIStateSynchronization {
    active_editor: Option<String>,
    cursor_positions: HashMap<String, (u32, u32)>,  // Document -> (line, col)
    selection_ranges: HashMap<String, (u32, u32)>,   // Document -> (start, end)
    view_state: ViewState {
        zoom_level: f32,
        sidebar_visible: bool,
        panel_visible: bool,
        status_bar_visible: bool,
    },
    theme: String,
    layout: LayoutState,
}

Real-time Update System:

Update Flow:

Queue updates as they occur
Subscriber management per target
Periodic broadcast (100ms)
Emit events via Tauri

Subscription Model:

// Subscribe to updates for a target
sync.subscribe_to_updates("file-changes", "window-1").await?;

// Queue updates
sync.queue_update(RealTimeUpdate { target:"file-changes".to_string(), data:modified_content })
	.await?;

// Broadcasts go to:
// - "real-time-update-window-1"
// - "real-time-update-window-2"
// etc...

Tauri Commands:

mountain_add_document_for_sync - Add document to sync tracking
mountain_get_sync_status - Get current sync status
mountain_subscribe_to_updates - Subscribe to real-time updates

Events Emitted:

mountain_sync_status_update - Sync status changes
mountain_performance_update - Performance metrics
real-time-update-{subscriber} - Real-time updates

Initialization:

// In Mountain setup
let sync = Arc::new(WindAdvancedSync::new(runtime));
app_handle.manage(sync.clone());

// Start sync tasks
let sync_clone = sync.clone();
tokio::spawn(async move {
sync_clone.start_synchronization().await;
});

Usage Examples:

Add Document for Sync:

// From Wind TypeScript
await invoke('mountain_add_document_for_sync', {
    documentId: 'file-123',
    filePath: '/project/src/main.rs'
});

Check Sync Status:

const status = await invoke('mountain_get_sync_status');
console.log(`Synced: ${status.syncedDocuments}/${status.totalDocuments}`);

Subscribe to Updates:

await invoke('mountain_subscribe_to_updates', {
    target: 'file-changes',
    subscriber: 'my-window-id'
});

// Listen for updates
app.handle.listen('real-time-update-my-window-id', (event) => {
    console.log('Real-time update:', event.payload);
});

Performance Tracking:

Metrics Collected:

Total messages sent/received
Average latency
Connection uptime
Error count
Sync duration

Logged on Every Operation:

trace!(
"Document sync completed: {} success, {} errors, {:.2}ms",
success_count,
error_count,
sync_duration.as_millis()
);

Integration with Other Modules:

TauriIPCServer:

Used for broadcasting events to Wind
