🚨 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>

# 期待結果: タイムアウトでデッドロック確認
# 出力例:
# [Console LOG] ✅ SocketBox作成成功
# [Console LOG] bind()実行開始...
# (ここで無限ブロック)
```
### **2. 他のBox正常動作確認**
```bash
# 実行コマンド
./target/release/nyash test_other_boxes_working.hako

# 期待結果: 正常完了
# 出力例:
# [Console LOG] ✅ ArrayBox正常: size=1
# [Console LOG] ✅ MapBox正常: value=test_value
# [Console LOG] 🎉 他のBox全て正常動作: 4件成功
```
### **3. SocketBox全メソッドテスト**
```bash
# 実行コマンド (30秒でタイムアウト)
timeout 30s ./target/release/nyash test_socket_methods_comprehensive.hako

# 期待結果: 最初のtoString()でデッドロック
# 出力例:
# [Console LOG] Test 1: toString()実行...
# (ここで無限ブロック)
```
## 🔧 **ビルド手順**
```bash
# フルリビルド
cargo clean
cargo build --release -j32
# 確認
ls -la target/release/nyash
```
## 📊 **デバッグログ確認ポイント**
### **正常Box vs SocketBoxの出力差異**
```bash
# 正常Box例ArrayBox:
✅ ARRAY_METHOD: push() called
✅ ArrayBox push completed
# SocketBox問題:
🔥 SOCKETBOX CLONE DEBUG: Arc addresses match = true
# ここで停止 - 🔥 SOCKET_METHOD: bind() called が出力されない
```
### **問題箇所ピンポイント**
```rust
// src/interpreter/expressions.rs:462-464
// この downcast_ref または obj_value 取得でデッドロック
if let Some(socket_box) = obj_value.as_any().downcast_ref::<SocketBox>() {
let result = self.execute_socket_method(socket_box, method, arguments)?;
```
## 📝 **実行後報告フォーマット**
```
## テスト実行結果
### Test 1: 最小デッドロック再現
- 実行時間: XX秒タイムアウト
- 最後の出力: "bind()実行開始..."
- 結果: ✅ デッドロック再現確認 / ❌ 正常動作
### Test 2: 他のBox正常動作
- 実行時間: XX秒
- 成功Box数: X件
- 結果: ✅ 正常動作 / ❌ 異常あり
### Test 3: Socket全メソッド
- デッドロック発生メソッド: toString/isServer/bind/close
- 結果: ✅ 全メソッドでデッドロック / ❌ 一部のみ問題
## 修正内容
