Phase 0 Critical Stability Fixes: CRASH PREVENTION: ✅ Safe clipboard operations with panic recovery and timeouts ✅ Async API calls to prevent UI blocking ✅ Input buffering during long operations ✅ Comprehensive panic recovery wrappers ✅ Context management with proper timeouts RESPONSIVENESS: ✅ Non-blocking API calls with background goroutines ✅ Input keystroke buffering during AI responses ✅ Async operation tracking and cancellation ✅ Safe memory and pointer operations RESOURCE MANAGEMENT: ✅ Proper context timeouts (30s prompts, 15s shell, 5s files) ✅ Background operation cleanup ✅ Memory leak prevention ✅ Goroutine safety improvements TESTING: ✅ Comprehensive test suite for crash scenarios ✅ Stress tests for concurrent operations ✅ Clipboard failure simulation ✅ Memory operation safety verification NEXT: Fix LSP process spawning (hundreds of rust-analyzer instances) NEXT: Fix MCP server startup/shutdown issues All tests pass. Ready for LSP and MCP process management fixes.
🚨 CRITICAL RESOURCE MANAGEMENT FIXES: LSP PROCESS SPAWNING FIXES: ✅ Fix hundreds of rust-analyzer instances eating RAM ✅ Process pool with max 2 processes per server type ✅ Process reuse and reference counting ✅ LRU eviction when hitting process limits ✅ Automatic cleanup of idle processes after 5 minutes ✅ Proper process lifecycle management on shutdown MCP SERVER IMPROVEMENTS: ✅ Health monitoring with 30-second checks ✅ Automatic restart on failure (max 3 attempts) ✅ Graceful shutdown and resource cleanup ✅ Better error handling and logging ✅ Client lifecycle management PROCESS MONITORING TOOLS: ✅ Real-time process statistics ✅ Health check and alerting system ✅ CLI tools for monitoring and debugging ✅ Automatic detection of resource leaks BEFORE: Hundreds of rust-analyzer processes spawned per session AFTER: Maximum 2 processes per LSP server type, automatic cleanup IMPACT: - Prevents RAM exhaustion from excessive LSP processes - Eliminates MCP server startup/shutdown issues - Provides monitoring tools for process health - Ensures proper resource cleanup on exit Ready for testing and validation.
