1//! # Wind Advanced Synchronization - Real-time Document & UI Sync
2//!
3//! **File Responsibilities:**
4//! This module implements advanced synchronization features that keep Wind's
5//! frontend state in sync with Mountain's backend state in real-time. It
6//! handles document changes, UI state updates, and broadcast updates across the
7//! editor ecosystem.
8//!
9//! **Architectural Role in Wind-Mountain Connection:**
10//!
11//! The WindAdvancedSync module is responsible for:
12//!
13//! 1. **Document Synchronization:** Real-time tracking and synchronization of
14//!    document changes between Wind (frontend editor) and Mountain (backend
15//!    services)
16//! 2. **UI State Sync:** Synchronizing UI state across multiple editor windows
17//!    - Cursor positions
18//!    - Selection ranges
19//!    - Zoom levels
20//!    - Theme and layout
21//! 3. **Real-time Broadcasting:** Broadcasting updates to interested
22//!    subscribers
23//! 4. **Conflict Detection:** Identifying and handling conflicting changes
24//! 5. **Performance Tracking:** Monitoring sync performance and health
25//!
26//! **Synchronization Architecture:**
27//!
28//! **Three Sync Layers:**
29//!
30//! **1. Document Synchronization (Every 5 seconds):**
31//! ```text
32//! Wind Editor (User Edits)
33//!     |
34//!     | Detect changes
35//!     v
36//! WindAdvancedSync
37//!     |
38//!     | Check for conflicts
39//!     v
40//! Mountain Services
41//!     |
42//!     | Apply changes
43//!     v
44//! File System / Storage
45//! ```
46//!
47//! **2. UI State Synchronization (Every 1 second):**
48//! ```text
49//! Wind UI Window
50//!     |
51//!     | Capture state (cursor, selection, zoom)
52//!     v
53//! WindAdvancedSync
54//!     |
55//!     | Update internal state
56//!     v
57//! Apply to other windows
58//! ```
59//!
60//! **3. Real-time Updates (Every 100ms):**
61//! ```text
62//! Subscribed Listeners
63//!     ^
64//!     | Broadcast updates
65//!     |
66//! WindAdvancedSync
67//!     |
68//!     | Queue updates
69//!     v
70//! Update Queue
71//! ```
72//!
73//! **Document Synchronization States:**
74//!
75//! ```rust
76//! enum SyncState {
77//! 	Modified,   // Changed locally, not synced
78//! 	Synced,     // Successfully synchronized
79//! 	Conflicted, // Conflicts need resolution
80//! 	Offline,    // Cannot sync (offline)
81//! }
82//! ```
83//!
84//! **Change Types Supported:**
85//!
86//! ```rust
87//! enum ChangeType {
88//! 	Update, // File content updated
89//! 	Insert, // New file created
90//! 	Delete, // File deleted
91//! 	Move,   // File moved/renamed
92//! 	Other,  // Other changes
93//! }
94//! ```
95//!
96//! **Conflict Detection (Microsoft-Inspired):**
97//!
98//! **Detection Criteria:**
99//! - Document modified recently (within 10 seconds of last sync)
100//! - Document is already in conflicted state
101//! - Multiple simultaneous changes detected
102//!
103//! **Conflict Response:**
104//! ```rust
105//! return Err(format!(
106//! 	"Conflict detected: Document {} was modified recently ({}s ago)",
107//! 	document_id,
108//! 	current_time - document.last_modified
109//! ));
110//! ```
111//!
112//! **Error Recovery (Circuit Breaker Pattern):**
113//!
114//! **Circuit Breaker States:**
115//! 1. **Closed (Normal):** Operations proceed normally
116//! 2. **Open (Degraded):** Too many failures, slow down sync interval
117//! 3. **Half-Open (Testing):** Slowly testing if system recovered
118//!
119//! **Recovery Logic:**
120//! - Track consecutive failures (max 3)
121//! - On reaching limit: Increase sync interval to 30s
122//! - On success: Reset interval to 5s
123//! - Provides protection against cascading failures
124//!
125//! **Trackable Metrics:**
126//!
127//! **Sync.Status:**
128//! ```rust
129//! SyncStatus {
130//! 	total_documents:u32,       // All tracked documents
131//! 	synced_documents:u32,      // Successfully synced
132//! 	conflicted_documents:u32,  // Have conflicts
133//! 	offline_documents:u32,     // Cannot sync
134//! 	last_sync_duration_ms:u64, // Time for last sync
135//! }
136//! ```
137//!
138//! **UI State Tracked:**
139//!
140//! ```rust
141//! UIStateSynchronization {
142//!     active_editor: Option<String>,
143//!     cursor_positions: HashMap<String, (u32, u32)>,  // Document -> (line, col)
144//!     selection_ranges: HashMap<String, (u32, u32)>,   // Document -> (start, end)
145//!     view_state: ViewState {
146//!         zoom_level: f32,
147//!         sidebar_visible: bool,
148//!         panel_visible: bool,
149//!         status_bar_visible: bool,
150//!     },
151//!     theme: String,
152//!     layout: LayoutState,
153//! }
154//! ```
155//!
156//! **Real-time Update System:**
157//!
158//! **Update Flow:**
159//! 1. Queue updates as they occur
160//! 2. Subscriber management per target
161//! 3. Periodic broadcast (100ms)
162//! 4. Emit events via Tauri
163//!
164//! **Subscription Model:**
165//! ```rust
166//! // Subscribe to updates for a target
167//! sync.subscribe_to_updates("file-changes", "window-1").await?;
168//!
169//! // Queue updates
170//! sync.queue_update(RealTimeUpdate { target:"file-changes".to_string(), data:modified_content })
171//! 	.await?;
172//!
173//! // Broadcasts go to:
174//! // - "real-time-update-window-1"
175//! // - "real-time-update-window-2"
176//! // etc...
177//! ```
178//!
179//! **Tauri Commands:**
180//!
181//! - `mountain_add_document_for_sync` - Add document to sync tracking
182//! - `mountain_get_sync_status` - Get current sync status
183//! - `mountain_subscribe_to_updates` - Subscribe to real-time updates
184//!
185//! **Events Emitted:**
186//!
187//! - `mountain_sync_status_update` - Sync status changes
188//! - `mountain_performance_update` - Performance metrics
189//! - `real-time-update-{subscriber}` - Real-time updates
190//!
191//! **Initialization:**
192//!
193//! ```text
194//! // In Mountain setup
195//! let sync = Arc::new(WindAdvancedSync::new(runtime));
196//! app_handle.manage(sync.clone());
197//!
198//! // Start sync tasks
199//! let sync_clone = sync.clone();
200//! tokio::spawn(async move {
201//! sync_clone.start_synchronization().await;
202//! });
203//! ```
204//!
205//! **Usage Examples:**
206//!
207//! **Add Document for Sync:**
208//! ```typescript
209//! // From Wind TypeScript
210//! await invoke('mountain_add_document_for_sync', {
211//!     documentId: 'file-123',
212//!     filePath: '/project/src/main.rs'
213//! });
214//! ```
215//!
216//! **Check Sync Status:**
217//! ```typescript
218//! const status = await invoke('mountain_get_sync_status');
219//! console.log(`Synced: ${status.syncedDocuments}/${status.totalDocuments}`);
220//! ```
221//!
222//! **Subscribe to Updates:**
223//! ```typescript
224//! await invoke('mountain_subscribe_to_updates', {
225//!     target: 'file-changes',
226//!     subscriber: 'my-window-id'
227//! });
228//!
229//! // Listen for updates
230//! app.handle.listen('real-time-update-my-window-id', (event) => {
231//!     console.log('Real-time update:', event.payload);
232//! });
233//! ```
234//!
235//! **Performance Tracking:**
236//!
237//! **Metrics Collected:**
238//! - Total messages sent/received
239//! - Average latency
240//! - Connection uptime
241//! - Error count
242//! - Sync duration
243//!
244//! **Logged on Every Operation:**
245//! ```text
246//! dev_log!("ipc",
247//! "Document sync completed: {} success, {} errors, {:.2}ms",
248//! success_count,
249//! error_count,
250//! sync_duration.as_millis()
251//! );
252//! ```
253//!
254//! **Integration with Other Modules:**
255//!
256//! **TauriIPCServer:**
257//! - Used for broadcasting events to Wind
258//! - Emits sync and performance updates
259//!
260//! **AdvancedFeatures:**
261//! - Collaboration sessions work with document sync
262//! - Shared focus on real-time updates
263//!
264//! **StatusReporter:**
265//! - Sync status reported to Sky for monitoring
266//! - Performance metrics shared
267//!
268//! **Future Enhancements:**
269//!
270//! - **Operational Transformation:** For collaborative editing
271//! - **Conflict Resolution UI:** User-facing conflict resolution
272//! - **Delta Sync:** Only sync changed portions
273//! - **Sync Prioritization:** Prioritize active documents
274//! - **Offline Sync Support:** Queue changes when offline
