🚨 Critical Issue #76: SocketBox Method Call Deadlock Investigation ## 🎯 Problem Identification Complete - SocketBox method calls (bind, isServer, toString) cause infinite blocking - Root cause: Method resolution pipeline deadlock before execute_socket_method - Other Box types (ArrayBox, StringBox, MapBox) work normally - Arc<Mutex> reference sharing confirmed working (Arc addresses match = true) ## 🔧 Debug Infrastructure Added - Comprehensive debug logging in socket_box.rs (bind, isServer, clone, toString) - Method call tracing in http_methods.rs - Deadlock detection points identified at interpreter expressions.rs:462-464 ## 📋 Issue #76 Created for Copilot Investigation - Systematic root cause analysis requirements (Architecture→Parser→Runtime levels) - Comprehensive test cases: minimal/comprehensive/comparison scenarios - Strict prohibition of band-aid fixes - architectural analysis required - Hypothesis: Multiple Arc<Mutex> combinations causing circular deadlock ## 🧪 Test Suite Added - test_socket_deadlock_minimal.nyash: Minimal reproduction case - test_socket_methods_comprehensive.nyash: All methods deadlock verification - test_other_boxes_working.nyash: Normal Box operation confirmation - SOCKETBOX_ISSUE_REPRODUCTION.md: Complete reproduction guide ## 📊 Impact Assessment - Phase 9 HTTP server implementation completely blocked - SocketBox functionality entirely non-functional - Critical blocker for production readiness - Requires immediate systematic investigation 🔥 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
