# Party 1 日志分析报告
|
||
|
||
## 📋 基本信息
|
||
|
||
- **Party ID**: 7c72c28f-082d-4ba4-a213-5b906abeb5cc
|
||
- **Party Index**: 1
|
||
- **Session ID**: f01810e9-4b0f-4933-a06a-0382124e0d25
|
||
- **Invite Code**: 6C72-753E-9C17
|
||
- **Threshold**: 2-of-3
|
||
|
||
## ✅ 成功的步骤
|
||
|
||
### 1. 应用启动和初始化 ✅
|
||
```
|
||
15:57:57.690 Setting up session event callback
|
||
15:57:58.140 Party registered: 7c72c28f...
|
||
15:57:58.186 Connected successfully
|
||
```
|
||
|
||
### 2. 会话创建 ✅
|
||
```
|
||
15:58:50.215 Creating keygen session
|
||
15:58:50.364 Create session response received
|
||
15:58:50.365 Session created: sessionId=f01810e9..., inviteCode=6C72-753E-9C17
|
||
```
|
||
|
||
**关键配置**:
|
||
- persistent_count: 1 (server-party-co-managed)
|
||
- external_count: 2 (两台手机)
|
||
- selected_server_parties: ["co-managed-party-3"]
|
||
|
||
### 3. 参与者加入 ✅
|
||
|
||
**第一次 participant_joined (15:58:50.385)**:
|
||
- selectedParties: [co-managed-party-3, 7c72c28f...] (2个)
|
||
- Party 1 自己加入成功
|
||
|
||
**第二次 participant_joined (15:58:58.210)**:
|
||
- selectedParties: [co-managed-party-3, 7c72c28f..., ca64e2b1...] (3个)
|
||
- Party 2 加入成功
|
||
|
||
### 4. session_started 事件触发 ✅
|
||
```
|
||
15:58:58.207 Session event: session_started
|
||
15:58:58.208 Session started event for keygen initiator, triggering keygen
|
||
15:58:58.210 Starting keygen as initiator: sessionId=..., t=2, n=3
|
||
```
|
||
|
||
### 5. 获取会话状态 ✅
|
||
```
|
||
15:58:58.271 Session status response:
|
||
status=in_progress
|
||
participants=3
|
||
- co-managed-party-3 (index=0, status=joined)
|
||
- 7c72c28f... (index=1, status=joined) ← 我
|
||
- ca64e2b1... (index=2, status=joined)
|
||
```
|
||
|
||
### 6. 启动 TSS keygen ✅
|
||
```
|
||
15:58:58.272 Starting keygen as initiator: sessionId=...
|
||
15:58:58.272 My party index: 1
|
||
15:58:58.301 [PROGRESS] Starting progress collection from native bridge
|
||
15:58:58.301 [JobManager] Launched job: progress_collection (active jobs: 3)
|
||
```
|
||
|

|
||
|
||
## 🚨 发现的问题
|
||
|
||
### 问题 1: Mark Party Ready 失败 🔴
|
||
|
||
```
|
||
15:58:58.318 E/GrpcClient: Mark party ready failed:
|
||
INTERNAL: optimistic lock conflict: session was modified by another transaction
|
||
```
|
||
|
||
**分析**:
|
||
- 乐观锁冲突(Optimistic Lock Conflict)
|
||
- 说明多个参与者同时尝试更新会话状态
|
||
- 这个错误导致 Party 1 **没有成功标记为 ready**
|
||
|
||
**影响**:
|
||
- 服务器可能认为 Party 1 还没有准备好
|
||
- 可能影响 TSS 协议的启动
|
||
|
||
**根本原因**:
|
||
- TssRepository.startKeygenAsInitiator line 2138: `grpcClient.markPartyReady(sessionId, partyId)`
|
||
- 这个调用失败了,但**没有错误处理**
|
||
- 代码继续执行到 line 2141: `waitForKeygenResult()`
|
||
|
||
**代码片段**:
|
||
```kotlin
|
||
// Line 2138
|
||
grpcClient.markPartyReady(sessionId, partyId) // ← 失败但没有检查
|
||
|
||
// Line 2141
|
||
val keygenResult = tssNativeBridge.waitForKeygenResult(password) // ← 继续等待
|
||
```
|
||
|
||
---
|
||
|
||
### 问题 2: 534 个待处理消息堆积(最严重)🚨🚨🚨
|
||
|
||
```
|
||
15:58:58.345 W/GrpcClient: Has 534 pending messages - may have missed events
|
||
15:59:28.440 W/GrpcClient: Has 534 pending messages - may have missed events ← 30秒后还是534
|
||
```
|
||
|
||
**分析**:
|
||
- 消息队列堆积了534个未处理消息
|
||
- **30秒后还是534个**,说明消息完全没有被消费
|
||
- TSS 协议需要消息路由才能工作
|
||
|
||
**影响**:
|
||
- TSS 协议无法进行
|
||
- 参与者之间无法交换密钥生成的中间值
|
||
- 导致 keygen 卡死
|
||
|
||
**可能原因**:
|
||
1. **message_collection job 没有真正工作**
|
||
- 虽然日志显示启动了,但可能内部失败了
|
||
- 没有错误日志,可能被静默吞掉
|
||
|
||
2. **消息路由没有正确初始化**
|
||
- line 15:58:50.387: "Starting message routing: sessionId=..., routingPartyId=..."
|
||
- 但之后没有任何消息发送/接收日志
|
||
|
||
3. **markPartyReady 失败导致消息路由失效**
|
||
- 服务器可能只向 "ready" 的参与者发送消息
|
||
- 如果 Party 1 没有标记为 ready,可能收不到消息
|
||
|
||
---
|
||
|
||
### 问题 3: TssNativeBridge 完全没有日志 🔴
|
||
|
||
**预期应该有的日志**:
|
||
```
|
||
TssNativeBridge: keygenAsInitiator called with sessionId=...
|
||
TssNativeBridge: Keygen round 1/9
|
||
TssNativeBridge: Keygen round 2/9
|
||
...
|
||
TssNativeBridge: Keygen completed successfully
|
||
```
|
||
|
||
**实际**: 完全没有任何 TssNativeBridge 的输出!
|
||
|
||
**分析**:
|
||
- TssNativeBridge.startKeygen (line 63-88) **没有任何日志**
|
||
- 无法判断:
|
||
1. 是否成功调用了 native library
|
||
2. 是否立即失败
|
||
3. 是否在等待消息
|
||
|
||
**代码问题**:
|
||
```kotlin
|
||
// TssNativeBridge.kt:63-88
|
||
suspend fun startKeygen(...): Result<Unit> = withContext(Dispatchers.IO) {
|
||
try {
|
||
val participantsJson = gson.toJson(participants)
|
||
Tsslib.startKeygen(...) // ← 没有日志!
|
||
Result.success(Unit) // ← 立即返回
|
||
} catch (e: Exception) {
|
||
Result.failure(e) // ← 如果这里失败,也没有日志!
|
||
}
|
||
}
|
||
```
|
||
|
||
**建议添加日志**:
|
||
```kotlin
|
||
suspend fun startKeygen(...): Result<Unit> = withContext(Dispatchers.IO) {
|
||
try {
|
||
android.util.Log.d("TssNativeBridge", "startKeygen called: sessionId=$sessionId, partyIndex=$partyIndex")
|
||
val participantsJson = gson.toJson(participants)
|
||
android.util.Log.d("TssNativeBridge", "Calling native Tsslib.startKeygen...")
|
||
Tsslib.startKeygen(...)
|
||
android.util.Log.d("TssNativeBridge", "Tsslib.startKeygen returned successfully")
|
||
Result.success(Unit)
|
||
} catch (e: Exception) {
|
||
android.util.Log.e("TssNativeBridge", "startKeygen failed", e)
|
||
Result.failure(e)
|
||
}
|
||
}
|
||
```
|
||
|
||
---
|
||
|
||
### 问题 4: 没有进度更新 🔴
|
||
|
||
**预期应该有的日志**:
|
||
```
|
||
MainViewModel: Progress update: 1 / 9
|
||
MainViewModel: Progress update: 2 / 9
|
||
...
|
||
```
|
||
|
||
**实际**: 完全没有!
|
||
|
||
**分析**:
|
||
- progress_collection job 启动了(15:58:58.301)
|
||
- 但没有收集到任何进度
|
||
- 说明:
|
||
1. TssNativeBridge 没有报告进度
|
||
2. 或者 keygen 根本没有启动
|
||
|
||
---
|
||
|
||
## 🎯 根本原因推断
|
||
|
||
### 最可能的原因(按概率排序)
|
||
|
||
#### 1. markPartyReady 失败导致消息路由失效 (70%)
|
||
|
||
**链条**:
|
||
```
|
||
markPartyReady 失败
|
||
↓
|
||
服务器认为 Party 1 未准备好
|
||
↓
|
||
不向 Party 1 发送 TSS 消息
|
||
↓
|
||
Party 1 的 message_collection 收不到消息
|
||
↓
|
||
534 个消息堆积(可能是其他 party 发给自己的)
|
||
↓
|
||
TSS 协议无法进行
|
||
↓
|
||
keygen 卡死
|
||
```
|
||
|
||
**验证方法**:
|
||
- 检查服务器日志,看 Party 1 的状态是否为 `ready`
|
||
- 检查 Party 2 和 co-managed-party 的日志,看他们是否收到消息
|
||
|
||
---
|
||
|
||
#### 2. TssNativeBridge.startKeygen 静默失败 (20%)
|
||
|
||
**链条**:
|
||
```
|
||
Tsslib.startKeygen() 调用失败
|
||
↓
|
||
没有抛出异常(或被吞掉)
|
||
↓
|
||
返回 Result.success(Unit)
|
||
↓
|
||
代码继续执行到 waitForKeygenResult()
|
||
↓
|
||
永久等待(因为 keygen 没有真正启动)
|
||
```
|
||
|
||
**验证方法**:
|
||
- 添加 TssNativeBridge 日志
|
||
- 检查 native library 的日志输出
|
||
|
||
---
|
||
|
||
#### 3. 消息路由初始化失败 (10%)
|
||
|
||
**链条**:
|
||
```
|
||
Starting message routing (15:58:50.387)
|
||
↓
|
||
subscribeToTssMessages 失败(没有日志)
|
||
↓
|
||
无法接收 TSS 消息
|
||
↓
|
||
keygen 卡死
|
||
```
|
||

|
||
|
||
## 🔍 需要进一步调查
|
||
|
||
### 1. 其他 Party 的日志
|
||
|
||
**需要收集**:
|
||
- **Party 2** (ca64e2b1-8a7c-4cc9-a8c7-5667a206e674) 的日志
|
||
- **co-managed-party-3** 的服务器日志
|
||
|
||
**重点看**:
|
||
- 他们是否成功 `markPartyReady`?
|
||
- 他们是否收到/发送了 TSS 消息?
|
||
- 他们的 pending messages 数量?
|
||
- 他们的进度更新?
|
||
|
||
---
|
||
|
||
### 2. 服务器端状态
|
||
|
||
**需要检查**:
|
||
```bash
|
||
# 查询会话状态
|
||
curl -X GET https://mpc-grpc.szaiai.com/api/sessions/f01810e9-4b0f-4933-a06a-0382124e0d25
|
||
|
||
# 查询参与者状态
|
||
# 看 Party 1 (7c72c28f...) 的 status 是否为 "ready"
|
||
```
|
||
|
||
---
|
||
|
||
### 3. 添加更详细的日志
|
||
|
||
需要在以下位置添加日志:
|
||
|
||
#### TssNativeBridge.kt
|
||
```kotlin
|
||
suspend fun startKeygen(...): Result<Unit> {
|
||
android.util.Log.d("TssNativeBridge", "startKeygen: sessionId=$sessionId, partyIndex=$partyIndex, t=$thresholdT, n=$thresholdN")
|
||
android.util.Log.d("TssNativeBridge", "participants: $participants")
|
||
|
||
try {
|
||
val participantsJson = gson.toJson(participants)
|
||
android.util.Log.d("TssNativeBridge", "Calling native Tsslib.startKeygen...")
|
||
|
||
Tsslib.startKeygen(...)
|
||
|
||
android.util.Log.d("TssNativeBridge", "Tsslib.startKeygen returned (async)")
|
||
Result.success(Unit)
|
||
} catch (e: Exception) {
|
||
android.util.Log.e("TssNativeBridge", "startKeygen FAILED", e)
|
||
Result.failure(e)
|
||
}
|
||
}
|
||
```
|
||
|
||
#### TssRepository.kt
|
||
```kotlin
|
||
// Line 2138 - 检查 markPartyReady 结果
|
||
val markReadyResult = grpcClient.markPartyReady(sessionId, partyId)
|
||
if (markReadyResult.isFailure) {
|
||
android.util.Log.e("TssRepository", "Failed to mark party ready: ${markReadyResult.exceptionOrNull()?.message}")
|
||
// 考虑重试或返回错误
|
||
}
|
||
```
|
||
|
||
---
|
||
|
||
## 🛠️ 临时解决方案
|
||
|
||
### 方案 1: 重试 markPartyReady
|
||
|
||
修改 TssRepository.kt line 2138:
|
||
```kotlin
|
||
// 重试机制
|
||
repeat(3) { attempt ->
|
||
try {
|
||
grpcClient.markPartyReady(sessionId, partyId)
|
||
android.util.Log.d("TssRepository", "Successfully marked party ready on attempt ${attempt + 1}")
|
||
break
|
||
} catch (e: Exception) {
|
||
android.util.Log.w("TssRepository", "markPartyReady attempt ${attempt + 1} failed: ${e.message}")
|
||
if (attempt == 2) {
|
||
// 最后一次尝试失败,抛出错误
|
||
return@coroutineScope Result.failure(Exception("Failed to mark party ready after 3 attempts"))
|
||
}
|
||
delay(1000) // 等待1秒后重试
|
||
}
|
||
}
|
||
```
|
||
|
||
### 方案 2: 添加完整的日志
|
||
|
||
在所有关键位置添加日志,特别是:
|
||
- TssNativeBridge.startKeygen
|
||
- markPartyReady
|
||
- message_collection job
|
||
|
||
---
|
||
|
||
## 📊 总结
|
||
|
||
### 确定的问题
|
||
1. ✅ markPartyReady 失败(optimistic lock conflict)
|
||
2. ✅ 534个消息堆积未处理
|
||
3. ✅ TssNativeBridge 没有任何日志
|
||
4. ✅ 没有进度更新
|
||
|
||
### 最可能的根本原因
|
||
**markPartyReady 失败 → 服务器不发送消息给 Party 1 → 消息路由失效 → keygen 卡死**
|
||
|
||
### 下一步行动
|
||
1. **立即**: 收集 Party 2 和 co-managed-party 的日志
|
||
2. **短期**: 添加 TssNativeBridge 日志
|
||
3. **中期**: 添加 markPartyReady 重试机制
|
||
4. **长期**: 改进错误处理和日志记录
|
||
