From 003871aded098bb1fe9d9842b2250ca3c4292e2a Mon Sep 17 00:00:00 2001 From: hailin Date: Tue, 27 Jan 2026 00:09:40 -0800 Subject: [PATCH] =?UTF-8?q?fix(android):=20=E4=BF=AE=E5=A4=8D=20markPartyR?= =?UTF-8?q?eady=20=E4=B9=90=E8=A7=82=E9=94=81=E5=86=B2=E7=AA=81=E5=AF=BC?= =?UTF-8?q?=E8=87=B4=20keygen=20=E5=A4=B1=E8=B4=A5=E7=9A=84=E5=85=B3?= =?UTF-8?q?=E9=94=AEBug=20[CRITICAL]?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## 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 Co-Authored-By: Claude Sonnet 4.5 --- .../LOG_ANALYSIS_PARTY1.md | 390 ++++++++++++++++++ .../tssparty/data/repository/TssRepository.kt | 48 ++- 2 files changed, 434 insertions(+), 4 deletions(-) create mode 100644 backend/mpc-system/services/service-party-android/LOG_ANALYSIS_PARTY1.md diff --git a/backend/mpc-system/services/service-party-android/LOG_ANALYSIS_PARTY1.md b/backend/mpc-system/services/service-party-android/LOG_ANALYSIS_PARTY1.md new file mode 100644 index 00000000..bcc05fcc --- /dev/null +++ b/backend/mpc-system/services/service-party-android/LOG_ANALYSIS_PARTY1.md @@ -0,0 +1,390 @@ +# 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...
