+# Face SDK 崩溃调试指南
+
+本文档说明如何配合 AI 定位 `libface_sdk.so` 里的崩溃 / 异常。核心思路：**把 Vulkan 每一次异常的上下文写进一个持久日志文件里，崩溃或画面卡住后把这份文件发给 AI 分析。**
+
+---
+
+## 一、已经加好的东西（不需要你做什么）
+
+### 1. `DebugLog` 模块（`app/src/main/cpp/DebugLog.{h,cpp}`）
+
+- 线程安全；
+- 每条日志带**时间戳 + 线程 ID（tid）**；
+- 写到 App **私有目录下的文件** —— 不会被 logcat 自动清掉；
+- 每写一行 `fflush`，进程挂了也不丢最后几行；
+- 文件大小超过 2MB 自动滚动到 `.old`；
+- 同步把日志镜像到 logcat，tag 是 `FACE_DBG`。
+
+### 2. 打点位置
+
+| 位置 | 打点内容 | 用途 |
+|---|---|---|
+| `android_main` 启动 | pid、tid、日志文件绝对路径 | 每次启动一条，作为分段锚点 |
+| 渲染循环心跳 | 每 600 帧一条：`frame=X exceptions_so_far=Y` | 判断启动多久后崩溃 / 异常持续性 |
+| `try/catch` 兜底 | 首 10 次异常每次都打，之后每 120 次打一次 | **Vulkan 异常不会再让进程硬崩**，留住现场 |
+| `handle_cmd` | 每个 `APP_CMD_*` 事件（尤其 `INIT_WINDOW`/`TERM_WINDOW`/`CONFIG_CHANGED`） | 旋转 / 切后台 / 锁屏场景的时间线 |
+| `FaceApp::initVulkan` 入/出口 | 调用次数、`_applicationInited` / `_faceAppInited` / `_sceondInited` 状态 | 判断是否被多次重复调用 |
+| `processImageNative` / `passDataToNative` | 每 300 次调用打一条 tid | 验证"Java 两个回调在不同线程并发调 Vulkan"假设 |
+| `Application::drawFrame` 里的 4 次 Vulkan 调用 | 非 `VK_SUCCESS` 时打印数值 + 字符串名（例如 `-4 (VK_ERROR_DEVICE_LOST)`） | **最关键的证据** |
+
+### 3. 关键行为变化
+
+**⚠️ 现在 `drawFrame` 里 Vulkan 抛出的异常会被 `try/catch` 吃掉 —— App 不会再因为这类问题硬崩溃。**
+
+- 好处：你能继续跑、继续复现、日志一直在写；
+- 代价：出问题时表现从"崩溃"变成"**画面卡住 / 黑屏 / 不再更新**"。
+- 如果想暂时回到硬崩行为：把 `app/src/main/cpp/main.cpp` 里那段 `try { g_Application->drawFrame(...); } catch (...) { ... }` 改回直接 `g_Application->drawFrame(frameTime);` 即可。
+
+---
+
+## 二、怎么把日志文件取出来
+
+### 方式 A：`run-as`（推荐，不需要 root）
+
+```bash
+adb shell "run-as com.inewme.uvmirror cat files/face_sdk_debug.log" > face_sdk_debug.log
+adb shell "run-as com.inewme.uvmirror cat files/face_sdk_debug.log.old" > face_sdk_debug.log.old
+```
+
+> `.old` 只有文件滚动过一次才存在，没有可以忽略错误。
+
+### 方式 B：直接看 logcat（实时）
+
+```bash
+adb logcat -s FACE_DBG
+```
+
+和文件内容基本一致。跑较久的话还是文件更可靠。
+
+### 方式 C：从 App 里拿路径
+
+启动后 `FACE_DBG` 第一条日志长这样：
+
+```
+[10:12:03.041][tid=12345] android_main start, pid=23456 tid=12345, logPath=/data/user/0/com.inewme.uvmirror/files/face_sdk_debug.log
+```
+
+照这个路径走就对了。
+
+---
+
+## 三、你现在要做的事（B 方案：两种场景都复现一次）
+
+### 场景 1：旋转崩溃（已确认必现）
+
+1. 打开 App，等初始化完成（画面能看到人脸渲染）。
+2. **旋转一次屏幕**。
+3. 等 3~5 秒让日志写进去。
+4. 取 `face_sdk_debug.log`，**不要清文件**，继续场景 2。
+
+期望看到的关键行：
+```
+>> handle_cmd APP_CMD_TERM_WINDOW(...)
+>> handle_cmd APP_CMD_INIT_WINDOW(...)
+FaceApp::initVulkan enter, call#2 ...
+drawFrame[NNN] vkAcquireNextImageKHR -> ??? (...)
+!!! drawFrame std::exception (frame=NNN count=M): failed to ...
+```
+
+注意里面那个 `???` —— 这是整件事的核心证据。
+
+### 场景 2：长时间运行崩溃（之前那个 10 分钟左右的）
+
+**不要退出 App，接着跑**。现在即使旋转触发了异常，进程没死，我们希望看后续会不会再出另一种 VkResult：
+
+1. 尽量不操作（不切后台、不旋转、不锁屏，让 App 持续渲染）。
+2. 连续跑 **15~20 分钟**，观察是否复现之前的"无外部事件崩溃"。
+3. 复现后（或稳定 20 分钟未复现也行），再取一次 `face_sdk_debug.log`（这次会覆盖场景 1 的那份，所以务必**先把场景 1 的单独保存好**）。
+
+期望看到的关键行（如果真的是 DEVICE_LOST）：
+```
+drawFrame[NNN] vkQueueSubmit -> -4 (VK_ERROR_DEVICE_LOST) ...
+```
+或者某个 Vulkan 调用返回其他错误码。
+
+### 辅助信息（手边有就顺便记一下）
+
+| 项 | 为什么要 |
+|---|---|
+| 机型 + Android 版本 | GPU 驱动差异；Adreno / Mali / Xclipse 表现差别大 |
+| 复现时手机是不是很烫 | 排查 GPU 温控 / thermal throttling |
+| 旋转时是"横屏 → 竖屏"还是"竖屏 → 横屏" / 多次连续旋转？ | 某些机型一次 vs 多次触发行为不同 |
+| 10 分钟崩溃时 App 在做什么（有在切换 motion 吗？） | 帮助排除 `changeMotionList` 相关路径 |
+
+---
+
+## 四、发给 AI 的时候包含什么
+
+最小集：
+
+1. `face_sdk_debug.log`（场景 1 旋转那份）
+2. `face_sdk_debug.log`（场景 2 长跑那份）
+3. 如果文件很大，**完整发**比截断发强（AI 主要关心最后几千行）
+4. 一句话说明这份日志对应场景 1 还是场景 2，是否复现了
+
+不需要的：
+
+- logcat 完整 dump（体积太大且大多无关，除非 AI 主动问特定 tag）
+- 录屏
+- 源代码（AI 已经能看到仓库）
+
+---
+
+## 五、当前未解决的假设，等日志验证
+
+| 假设 | 对应 VkResult | 修法 |
+|---|---|---|
+| 旋转导致 surface 失效未处理 | `VK_ERROR_OUT_OF_DATE_KHR` (-1000001004) 或 `VK_ERROR_SURFACE_LOST_KHR` (-1000000000) 或 `VK_SUBOPTIMAL_KHR` (1000001003) | 实现 `APP_CMD_TERM_WINDOW` 销毁流程 + swapchain 重建 |
+| Java 多线程并发提交 graphicsQueue 导致 GPU 长时间后挂 | `VK_ERROR_DEVICE_LOST` (-4)，且 `processImageNative` / `passDataToNative` 日志里 tid 不同 | 给所有 `vkQueueSubmit`/`vkQueuePresentKHR` 加全局 queue mutex |
+| 驱动 bug / 温度导致 GPU hang | `VK_ERROR_DEVICE_LOST` (-4)，单线程也出 | 捕获并尝试重建 device，或上报给机型厂商 |
+| 资源累积泄漏 | `VK_ERROR_OUT_OF_DEVICE_MEMORY` (-2) 或 `VK_ERROR_TOO_MANY_OBJECTS` | 排查 `beginSingleTimeCommands`/`processWithVulkan` 路径 |
+
+---
+
+## 六、日志样例（便于你确认打印是否正常）
+
+正常启动应该看到：
+```
+========== DebugLog opened @ 2026-04-23 14:05:12 (pid=12345) ==========
+[14:05:12.019][tid=12345] android_main start, pid=12345 tid=12345, logPath=/data/user/0/com.inewme.uvmirror/files/face_sdk_debug.log

+[14:05:13.420][tid=12345] FaceApp::initVulkan exit, call#1 _applicationInited=1 _faceAppInited=1 _secondfaceAppInited=1
+[14:05:13.420][tid=12345] handle_cmd APP_CMD_INIT_WINDOW: initVulkan() returned, isInited=1
+[14:05:13.421][tid=12345] << handle_cmd APP_CMD_INIT_WINDOW done

+[14:05:14.008][tid=67891] passDataToNative #1 tid=67891 point_count=468 w=480 h=480
+[14:05:35.200][tid=12345] heartbeat: frame=600 exceptions_so_far=0
+```
+
+旋转时如果触发异常应该看到：
+```
+[14:06:10.112][tid=12345] >> handle_cmd APP_CMD_CONFIG_CHANGED(8) tid=12345
+[14:06:10.113][tid=12345] >> handle_cmd APP_CMD_TERM_WINDOW(2) tid=12345
+[14:06:10.113][tid=12345] handle_cmd APP_CMD_TERM_WINDOW: (no handler yet, ...)
+[14:06:10.113][tid=12345] << handle_cmd APP_CMD_TERM_WINDOW done
+[14:06:10.250][tid=12345] >> handle_cmd APP_CMD_INIT_WINDOW(1) tid=12345
+[14:06:10.250][tid=12345] FaceApp::initVulkan enter, call#2 _applicationInited=1 _faceAppInited=1 _secondfaceAppInited=0
+[14:06:10.250][tid=12345] FaceApp::initVulkan exit, call#2 _applicationInited=1 _faceAppInited=1 _secondfaceAppInited=1
+[14:06:10.280][tid=12345] drawFrame[1234] vkAcquireNextImageKHR -> -1000001004 (VK_ERROR_OUT_OF_DATE_KHR) currentFrame=0
+[14:06:10.280][tid=12345] !!! drawFrame std::exception (frame=1234 count=1): failed to acquire swap chain image!
+```
+
+**只要日志里能看到 `vkXxxKHR -> <数值> (<名字>)` 这一行，诊断就成立了。**
+
+---
+
+## 七、文件清单（仅供参考，日常不用动）
+
+```
+app/src/main/cpp/
+  DebugLog.h        新增
+  DebugLog.cpp      新增
+  main.cpp          改：日志初始化 / 心跳 / try-catch / cmd 日志 / JNI tid
+vulkan/
+  Application.cpp   改：drawFrame 4 处 VkResult 日志 + VkResultStr
+  FaceApp.cpp       改：initVulkan 入/出口日志
+CMakeLists.txt      改：加入 DebugLog.cpp 到 Android 构建
+```

+// CrashHandler.cpp
+//
+// Async-signal-safe crash dumper for the face_sdk native library. The goal
+// is that the next time the app dies (e.g. another FORTIFY: pthread_mutex_lock
+// called on a destroyed mutex from inside the Vulkan driver) we don't only
+// have logcat — we also have a self-contained dump on the device's app data
+// directory that the user can pull off and send back, even after a reboot.
+//
+// Why we need this:
+//   - DebugLog only writes "happy path" events. The Vulkan crash happens
+//     synchronously inside vkQueueSubmit / vkFreeCommandBuffers — there is
+//     no DebugLog call near the crash site, so the file log just stops.
+//   - logcat survives across the crash (debuggerd dumps the backtrace there)
+//     but logcat is volatile: a couple of reboots, a logcat -c, or a long
+//     idle period and it's gone. We want a persistent file.
+//   - tombstones in /data/tombstones/ are root-only on consumer devices.
+//
+// Implementation notes:
+//   - Inside a signal handler we MUST stick to async-signal-safe APIs
+//     (man 7 signal-safety). That rules out fprintf / snprintf / malloc.
+//     We use write(), our own integer-to-string conversion, and a single
+//     pre-opened fd. dladdr() is technically not on the POSIX safe list but
+//     bionic's implementation only takes one rwlock and is widely used in
+//     other crash dumpers (breakpad, crashpad, libunwindstack). We accept
+//     that risk because the alternative is no symbol at all.
+//   - We use <unwind.h> (_Unwind_Backtrace) instead of execinfo.h because
+//     bionic doesn't ship execinfo.h on all NDK levels, and _Unwind_Backtrace
+//     is the same primitive Android's own tombstoned uses.
+//   - We re-raise the original signal with the default handler at the end so
+//     the OS still produces a tombstone / ANR record for vendors that
+//     read /data/tombstones/.
