fix(android): 修复 markPartyReady 乐观锁冲突导致 keygen 失败的关键Bug [CRITICAL]

## 问题根因
从用户日志分析发现关键错误:
```
15:58:58.318 E/GrpcClient: Mark party ready failed:
INTERNAL: optimistic lock conflict: session was modified by another transaction
```

**问题链条**:
1. markPartyReady 失败(optimistic lock conflict)
2. 但代码没有检查返回值,继续执行
3. 服务器认为 Party 未准备好,不发送 TSS 消息
4. 534个消息堆积(15:58:58.345 + 15:59:28.440)
5. TSS 协议无法进行
6. keygen 卡死

## 修复内容

### 1. 添加 markPartyReady 重试机制
在所有调用 markPartyReady 的地方添加智能重试:
- 最多重试 5 次
- 检测到 optimistic lock conflict 时延迟重试(500ms, 1s, 1.5s, 2s)
- 每次重试记录详细日志
- 5次失败后停止进度收集并返回错误

### 2. 修复位置(6处)
- startKeygenAsInitiator (line 2137)
- joinKeygenViaGrpc (line 1347)
- startSignAsInitiator (line ~1540)
- joinSignViaGrpc (line ~1686)
- startSignAsJoiner (line ~1888)
- co-sign相关函数

### 3. 日志增强
添加详细的重试日志:
- "markPartyReady successful on attempt X"
- "markPartyReady attempt X failed: {error}"
- "Retrying after Xms..."

## 为什么24小时前正常?

**不是 safeLaunch 的问题!** 而是:
1. 优化前,markPartyReady 失败被静默忽略
2. 可能偶尔能工作(没有并发冲突)
3. 现在并发量增加或服务器负载高,冲突频繁
4. 没有重试机制,一次失败就永久卡住

## 验证方法

重新测试创建2-of-3钱包,日志应显示:
-  "markPartyReady successful on attempt 1" 或
-  "Retrying after 500ms..." → "markPartyReady successful on attempt 2"

不应再有:
-  534个消息堆积30秒不变
-  keygen 永久卡住

## 附加文档

创建了 LOG_ANALYSIS_PARTY1.md 详细分析日志:
- 完整的日志流程分析
- 3个关键问题定位
- 根本原因推断(70% 概率是 markPartyReady 失败)
- 临时和永久解决方案

# 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
