Advanced IPC Features - Enhanced Synchronization & Collaboration

File Responsibilities: This module provides advanced features for the IPC layer that go beyond basic communication. It implements real-time collaboration support, performance optimization through caching, and enhanced monitoring capabilities.

Architectural Role in Wind-Mountain Connection:

The AdvancedFeatures module extends the IPC layer with:

1. Real-time Collaboration: Support for multi-user collaborative editing

   • Session management for collaborative workspaces
   • Participant tracking and permission management
   • Real-time document change broadcasting

2. Performance Optimization: Intelligent caching to reduce redundant operations

   • Message caching with TTL (Time-To-Live)
   • Cache hit/miss tracking and analytics
   • Automatic cleanup of expired cache entries

3. Advanced Monitoring: Detailed performance tracking and metrics

   • Message rate calculations (MPS - Messages Per Second)
   • Latency tracking (average, peak)
   • Error rate monitoring
   • Connection uptime tracking

4. Background Services: Continuous monitoring and cleanup tasks

   • Periodic performance metrics calculation
   • Cache cleanup at regular intervals
   • Session monitoring for inactivity

Key Features:

1. Collaboration Support:

CollaborationSessions:

CollaborationSession {
    session_id: String,
    participants: Vec<String>,
    active_documents: Vec<String>,
    last_activity: u64,
    permissions: CollaborationPermissions,
}

Permissions:

• can_edit: Allow editing
• can_view: Read-only access
• can_comment: Allow comments
• can_share: Allow inviting others

Session Management:

• create_collaboration_session() - Create new session
• add_participant() - Add user to session
• monitor_collaboration_sessions() - Track active sessions
• Automatic session cleanup on inactivity (5 minutes)

2. Message Caching:

Cache Structure:

MessageCache {
    cached_messages: HashMap<String, CachedMessage>,
    cache_hits: u64,
    cache_misses: u64,
    cache_size: usize,
}

CachedMessage:

CachedMessage {
	data:serde_json::Value,
	timestamp:u64,
	ttl:u64, // Time to live in seconds
}

Cache Operations:

• cache_message(id, data, ttl) - Store message
• get_cached_message(id) - Retrieve message
• Automatic TTL-based expiration
• Periodic cleanup every 60 seconds

Cache Effectiveness:

cache_hit_rate = cache_hits / (cache_hits + cache_misses) 

3. Performance Monitoring:

Metrics Tracked:

• total_messages_sent - Outgoing message count
• total_messages_received - Incoming message count
• average_processing_time_ms - Mean latency
• peak_message_rate - Maximum observed rate
• error_count - Total errors
• connection_uptime - Time connected

Calculations:

Average Processing Time:

new_avg = old_avg * (n - 1) / n + current_time / n 

Message Rate:

messages_per_second = total_messages / time_window_seconds

4. Background Services:

Performance Monitoring (Every 10 seconds):

• Calculate current performance metrics
• Emit metrics to Sky via IPC events
• Update connection uptime

Cache Cleanup (Every 60 seconds):

• Remove expired cache entries
• Update cache size count
• Log cleanup statistics

Session Monitoring (Every 30 seconds):

• Remove inactive sessions (5+ minutes idle)
• Emit session updates to subscribers
• Track session count

Tauri Commands:

• mountain_get_performance_stats - Get performance metrics
• mountain_get_cache_stats - Get cache statistics
• mountain_create_collaboration_session - Create collaboration session
• mountain_get_collaboration_sessions - Get all active sessions

Events Emitted:

• ipc-performance-stats - Performance metrics update
• collaboration-sessions-update - Active sessions list

Initialization:

// In Mountain setup
let features = AdvancedFeatures::new(runtime);
app_handle.manage(features.clone_features());
features.start_monitoring().await;

Usage Examples:

Caching a Message:

features.cache_message(
"config:editor".to_string(),
serde_json::json!({ "theme": "dark" }),
300 // 5 minutes TTL
).await?;

// Retrieve later
let cached = features.get_cached_message("config:editor").await;

Creating a Collaboration Session:

let permissions = CollaborationPermissions {
	can_edit:true,
	can_view:true,
	can_comment:true,
	can_share:false,
};

features
	.create_collaboration_session("project-alpha".to_string(), permissions)
	.await?;

features.add_participant("project-alpha", "user123").await?;

Monitoring Performance:

features.record_message_statistics(true, 15).await; // Sent, 15ms
let stats = features.get_performance_stats().await?;
println!("Average latency: {}ms", stats.average_processing_time_ms);

Integration with StatusReporter:

The AdvancedFeatures module works with StatusReporter:

• StatusReporter can call this module for detailed metrics
• Both modules emit events to Sky for monitoring
• Complementary monitoring at different levels

Advanced Features Future Enhancements:

• Intelligent Caching: LRU cache eviction, predictive caching
• Collaboration Cursors: Real-time cursor position sharing
• Conflict Resolution: Automatic conflict detection and resolution
• Presence Indicators: Show who is viewing/editing documents
• Change History: Track all collaborative changes with authors
