From 7d4499fdb029995fc2de3c7e005fc2e6b976d44a Mon Sep 17 00:00:00 2001 From: mufans <292045132@qq.com> Date: Thu, 9 Apr 2026 22:12:07 +0800 Subject: [PATCH 01/88] feat(attribution): handle anonymous inner classes and improve report accuracy MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Extract actual method names from anonymous inner class names (e.g. Outer$1) and stack traces, storing the enclosing method as context_method - Tag XML layout inflate calls as [XML布局] with call count and total time - Reorder report sections to put attribution data first, preventing truncation of core input when total content exceeds token budget - Add completeness check rule to report prompt to avoid missing entries - Switch CLI entry point to graph module and add hatchling build config Co-Authored-By: Claude Opus 4.6 --- prompts/report-generator.txt | 2 + pyproject.toml | 9 +- src/smartinspector/agents/attributor.py | 2 + src/smartinspector/commands/attribution.py | 122 +++++++++++++++++- .../graph/nodes/reporter/__init__.py | 16 ++- .../graph/nodes/reporter/formatter.py | 11 +- uv.lock | 2 +- 7 files changed, 155 insertions(+), 9 deletions(-) diff --git a/prompts/report-generator.txt b/prompts/report-generator.txt index b615466..6382839 100644 --- a/prompts/report-generator.txt +++ b/prompts/report-generator.txt @@ -24,7 +24,9 @@ 具体要求: -

145.00ms。该方法在主线程循环执行100,000次 `Math.sqrt` 计算,是导致主线程卡顿的直接原因。 -报告会通过 SI$ tag 将性能热点归因到具体源码位置,并给出优化建议: +**原因**:根据源码归因,该方法是CPU烧录测试代码,在主线程上执行密集的数学运算,每次循环约5ms,每200ms执行一次,严重阻塞了主线程的UI渲染。 -``` -### P0 RecyclerView 布局与数据绑定严重卡顿 +**调用链**:`CpuBurnWorker.startMainThreadWork$run 145ms` -现象:DemoAdapter.dispatchLayoutStep2 单次耗时 221.24ms,超出帧预算 15.5 倍。 -原因:onBindViewHolder 中存在 Thread.sleep、同步数据加载、主线程图片解码。

Glide/Coil 异步图片加载 -4. 使用 DiffUtil 增量更新 -``` +**建议**: +1. **移除或禁用测试代码**:在正式发布版本中,应移除或禁用此类用于测试的CPU烧录代码。 +2. **移至后台线程**:如果该逻辑是应用功能所需,必须将其移至后台线程(如使用 `CoroutineScope(Dispatchers.Default).launch` 或 `ExecutorService`)执行,避免阻塞主线程。 +3. **降低计算频率和强度**:如果必须在主线程执行,应大幅减少循环次数(例如从100,000次减少到1,000次以内)或延长执行间隔。 + +### P0 DemoAdapter.onBindViewHolder 存在多项耗时操作导致列表滑动卡顿 + +**现象**:`DemoAdapter.onBindViewHolder` 单次调用最高耗时 74.95ms,在测试期间共调用7次,累计耗时 202.29ms。该方法是导致帧#111严重卡顿(267.25ms)和 RecyclerView `dispatchLayoutStep2` 耗时 229.07ms 的主要原因。 + +**原因**:根据源码归因,该方法内存在多个阻塞主线程的耗时操作: +1. `doExpensiveWork()` 中调用了 `Thread.sleep(20)` 进行强制等待。 +2. `repository.loadItemsSync(5)` 进行同步数据加载。 +3. 执行了30次字符串拼接循环。 +4. 进行了 `Bitmap` 解码操作。 + +**调用链**:`LinearLayoutManager.onLayoutChildren 228.97ms → RV OnBindView 75.05ms → DemoAdapter.onBindViewHolder 74.95ms` + +**位置**:`app/src/main/java/com/smartinspector/hook/adapter/DemoAdapter.java:40-64` + +**建议**: +1. **移除 Thread.sleep**:在主线程中绝对禁止使用 `Thread.sleep()`,应立即移除。 +2. **异步加载数据**:将 `repository.loadItemsSync(5)` 改为异步加载(如使用 `LiveData`、`RxJava` 或 `Coroutine`),在数据准备好后再通知 `Adapter` 更新。 +3. **优化字符串构建**:使用 `StringBuilder` 替代多次 `+` 操作进行字符串拼接。 +4. **异步加载与缓存图片**:将 `Bitmap` 解码移至后台线程,并使用 `Glide`、`Picasso` 等图片加载库进行异步加载和缓存,避免每次绑定都解码。 + +### P1 MainActivity.onCreate 中延迟任务过多且存在潜在风险 + +**现象**:`MainActivity.onCreate` 耗时 14.67ms。方法中启动了多个 `Handler.postDelayed` 任务。 + +**原因**:根据源码归因,方法中启动了多个延迟任务:1) 5秒后加载数据,2) 500ms间隔的循环padding调整,3) 8秒后显示详情Fragment。过多的延迟任务可能阻塞主线程,500ms的循环任务可能造成不必要的性能开销,且使用 `Handler.postDelayed` 有潜在的内存泄漏风险。 + +**调用链**:`MainActivity.onCreate 14.67ms` + +**位置**:`app/src/main/java/com/smartinspector/hook/MainActivity.java:31-67` + +**建议**: +1. **合并或优化任务**:评估500ms循环任务的必要性,考虑是否可以合并或由事件驱动(如监听视图状态)来触发。 +2. **使用 View.post**:对于需要在主线程执行的延迟UI操作,优先使用 `View.post()` 或 `View.postDelayed()`,这可以自动处理 `View` 生命周期,降低内存泄漏风险。 +3. **使用 Lifecycle-aware 组件**:对于需要在特定生命周期执行的任务,考虑使用 `Lifecycle` 和 `Coroutine` 等现代架构组件来管理。 -完整报告示例见 [reports/perf_report_20260404_093038.md](reports/perf_report_20260404_093038.md)。 +### P1 DemoAdapter.onCreateViewHolder 加载复杂布局耗时 + +**现象**:`DemoAdapter.onCreateViewHolder` 单次调用最高耗时 4.89ms,在测试期间共调用7次,累计耗时 10.49ms。 + +**原因**:根据源码归因,该方法加载了复杂布局 `item_complex`。布局的复杂度直接影响 `inflate` 和后续测量、布局的速度。 + +**调用链**:`DemoAdapter.onCreateViewHolder 4.89ms` + +**位置**:`app/src/main/java/com/smartinspector/hook/adapter/DemoAdapter.java:33-37` + +**建议**: +1. **检查并简化布局**:使用 Layout Inspector 或 `ConstraintLayout` 的布局优化工具,检查 `item_complex.xml` 的层级,减少不必要的嵌套。 +2. **使用 ViewStub**:对于列表中并非立即显示的复杂部分,可以考虑使用 `ViewStub` 进行延迟加载。 +3. **启用视图复用**:确保 `RecyclerView` 和 `Adapter` 正确设置了 `setHasStableIds(true)` 并实现了 `getItemId()`,以优化视图复用。 + +### P1 item_complex.xml 布局嵌套过深导致inflate耗时 + +**现象**:`item_complex.xml` 的 inflate 操作单次最高耗时 4.77ms,在测试期间共执行7次,累计耗时 9.80ms。 + +**原因**:根据源码归因,该布局有4层嵌套,并且包含自定义视图 `HeavyDrawView`。深层级的嵌套会导致测量和布局过程计算量增大。 + +**调用链**:`inflate#item_complex 4.77ms` + +**位置**:`app/src/main/res/layout/item_complex.xml:1-64` + +**建议**: +1. **使用 ConstraintLayout 扁平化布局**:将根布局替换为 `ConstraintLayout`,利用其约束关系减少嵌套层级,目标是控制在2层以内。 +2. **优化 HeavyDrawView**:分析 `HeavyDrawView` 的 `onDraw` 方法,确保其绘制操作高效,避免在 `onDraw` 中分配对象或进行复杂计算。 +3. **使用 merge 标签**:如果该布局被 `include`,考虑在根节点使用 `` 标签以消除一层冗余的 `ViewGroup`。 + + +## 附录 + +**采集工具**:Smart

perfetto -c -`),增加在受限设备上的兼容性 +2. **自动降级机制**:当config模式启动perfetto失败时,自动降级到命令行模式继续采集 +3. **UID获取策略**:Shell方案通过 `linux.process_stats` 扫描 `/proc` 获取UID,解决冷启动阶段 `process` 表无数据时的包名匹配问题。SI目前依赖 `process` 表,可能在冷启动场景遗漏 + +--- + +### 2.2 特征提取(SQL查询) + +**Shell方案:** +- `2_trace_filter.py` 核心是直接的SQL查询 +- 查询维度覆盖:慢切片、线程状态、帧时间线、CPU采样、调用栈 +- 关键特性: + - 使用 `thread_state` 表区分"代码慢"还是"线程被挂起"(Running vs R/S/D) + - `actual_frame_timeline_slice` 帧级归因,区分App/SF问题 + - `perf_sample` + `stack_profile_callsite` CPU调用栈链表(Android 15+) + - `args` 表读取Slice附加参数(view_type, adapter_position) + - `package_list` 冷启动场景的反查表 + +**SI方案:** +- `PerfettoCollector` 的11个collect方法 +- `deterministic.py` 预计算层(纯Python,无LLM): + - 空场景检测(FPS=0, 无帧, CPU低) + - 严重度分类(P0/P1/P2,按设备帧预算动态阈值) + - 调用链时间分布(百分比 + 树形缩进) + - RV热点排名(max_ms, avg_ms) + - 卡顿帧关联(帧-Slice-输入事件三方关联) + - CPU热点识别 +- SI$自定义Tag系统:block/RV/inflate/view/handler/db/net/img/touch +- Block事件与Perfetto Slice通过timestamp bisect关联 + +**对比评估:** + +| 特征提取能力 | Shell方案 | SI方案 | 优势方 |

jank_type区分App/SF | USER_JANK_TYPES分类 | 持平 | +| 自定义Tag | 依赖atrace原生tag | SI$自定义Tag体系(覆盖8类场景) | **SI** | + +**SI可借鉴:** +1. **thread_state深度分析**:Shell方案利用 `thread_state` 表区分线程在Running(代码慢)和 S/D(被挂起/IO等待)状态的时间分布。SI的 `collect_sched` 只有end_state,缺少per-slice级别的线程状态分析。建议增加 `thread_state` 查询,将每个慢Slice关联其执行期间的线程状态分布,帮助区分"代码需要优化"和"线程被系统挂起"两种不同根因 +2. **package_list冷启动支持**:在冷启动场景中 `process` 表可能为空,Shell方案用 `package_list` 反查。SI应在 `pull_trace_from_device` 的config中确保 `linux.process_stats` 开启,并在包名匹配失败时 fallback 到 `package_list` 查询 +3. **CPU采样调用栈深度重建**:Shell方案通过 `stack_profile_callsite.parent_id` 递归重建完整调用链。SI的 `collect_cpu_hotspots` 已实现类似逻辑(callsite_map + 递归回溯),但可增加对 `stack_profile_mapping` 的查询,关联so/apk的映射信息,使native方法调用栈更可读 + +--- + +### 2.3 源码关联 + +**Shell方案:** +- `3_ai_reporter.sh` 纯Shell脚本实现 +- 流程:从trace_filter输出中提取类名 → 用find/grep在源码中定位文件 → 用sed/awk提取方法体 → 直接拼入AI Prompt +- 源码搜索范围:当前class文件 + import依赖 + 关联XML布局 +- 特点: + - **静态绑定**:在Prompt构造阶段一次性完成所有源码搜索 + - **确定性**:不依赖LLM做搜索决策,纯Shell脚本逻辑 + - **广度**:搜索依赖引用和关联XML布局,提供更完整的上下文 + +**SI方案:** +- `Attributor Agent` — LangChain agent with manual tool-call loop +- 流程:提取SI$切片 → 分类(java/xml/system)→ 分组 → 对每组执行 Glob→Grep→Read 三步搜索 +- 特点: + - **动态搜索**:LLM决定搜索策略,可以处理模糊/不规则的类名 + - **工具调用循环**:最多8轮迭代,LLM自主决定何时搜索完成 + - **Call Stack上下文**:利用parent chain和BlockMonitor堆栈辅助定位 + - **内部类处理**:匿名内部类($1/$2) → 搜索外部类 → 堆栈提取真实方法名 + - **LRU缓存**:避免重复读取文件 + - **Early termination**:连续3次搜索失败则终止 + - **结构化输出**:尝试with_structured_output,失败时fallback到RESULT行解析 + +**对比评估:** + +| 源码关联能力 | Shell方案 | SI方案 | 优势方 | +|-------------|-----------|--------|--------| +| 搜索策略 | 静态find/grep/sed | 动态LLM Glob→Grep→Read | **SI** | +| 搜索准确性 | 依赖类名匹配规则 | LLM理解模糊/不规则名称 | **SI** | +| 搜索范围 | 当前类+import依赖+XML | 当前类+内部类+堆栈提示 | **Shell**(依赖链更广) | +| 搜索效率 | 一次性Shell脚本,快速 | 多轮LLM调用,较慢 | **Shell** | +| 匿名内部类 | 未专门处理 | 完整处理(外部类+堆栈方法名) | **SI** | +| 错误容忍 | Shell脚本出错即中断 | Early termination + 缓存 + 重试 | **SI** | +| Token消耗 | 无(不使用LLM搜索) | 高(每轮LLM调用消耗token) | **Shell** | +| 上下文完整性 | 包含import依赖和关联XML | 仅搜索目标类和方法体 | **Shell** | +| BlockMonitor堆栈 | 未提及 | 堆栈关联+bisect时间匹配 | **SI** | +| 调用链上下文 | 无 | parent chain回溯+上下文摘要 | **SI** | + +**SI可借鉴:** +1. **依赖引用搜索**:当前SI只搜索目标类本身的方法体。Shell方案会额外搜索该类的import依赖和关联XML布局,为AI诊断提供更完整的上下文。建议在Attributor Agent中增加一步"关联搜索":Read目标文件后,提取import列表中的项目内类和关联的XML布局ID,一并读取 +2. **搜索效率优化**:Shell方案一次性完成所有源码搜索,而SI需要多轮LLM调用。对于类名和包名完整的简单场景,可以引入"快速路径":跳过LLM搜索决策,直接用确定性代码执行Glob→Grep→Read。只在模糊/匿名内部类场景才走LLM搜索路径 +3. **静态源码绑定模式**:提供一种"预处理模式"选项,在调用LLM之前先用确定性代码完成源码搜索,将结果直接注入Prompt,类似Shell方案的做法。好处是减少token消耗和LLM调用轮次 + +--- + +### 2.4 AI诊断 + +**Shell方案:** +- 单次LLM调用 +- 将SQL查询结果+源码片段一起注入Prompt +- LLM直接输出Markdown诊断报告 +- 优点:简单直接,一次调用完成 +- 缺点:LLM需要同时处理数据分析和报告生成两个任务,可能导致质量下降 + +**SI方案:** +- 三阶段Agent协作: + 1. **PerfAnalyzer**:接收deterministic预计算结论 + 原始数据 → 组织性能分析报告 + 2. **Attributor**:根据SI$切片搜索源码 → 返回归因结果(文件路径+方法体+行号) + 3. **Reporter**:综合性能分析 + 源码归因 + 待归因热点 → 生成最终报告 +- **混合架构**:确定性计算(deterministic.py)+ LLM语言生成 +- **Token控制**:消息窗口裁剪、LRU文件缓存、结构化输出探测、Early termination +- **多Provider支持**:结构化输出失败时自动fallback到文本解析 + +**对比评估:** + +| AI诊断能力 | Shell方案 | SI方案 | 优势方 | +|-----------|-----------|--------|--------| +| LLM调用次数 | 1次 | 3-5次(per_analyzer + attributor迭代 + reporter) | **Shell**(简单) | +| 分析精度 | 依赖LLM做算术 | 确定性预计算+LLM语言组织 |

硬编码Prompt | 模块化Agent+独立Prompt文件 | **SI** | +| 结果一致性 | 完全依赖LLM | 确定性部分保证一致 | **SI** | + +**SI可借鉴:** +1. **轻量模式**:参考Shell方案的单次调用模式,为SI增加一个"快速诊断"模式。跳过Attributor阶段,直接将perf_summary中的类名/方法名/耗时信息交给Reporter LLM,由LLM基于经验推测优化建议。适用场景:不需要精确源码定位的快速初筛 +2. **Token消耗优化**:Shell方案的Prompt是静态构造的,token消耗可控。SI的Attributor Agent每轮迭代都会增加消息历史。当前的消息窗口裁剪(keep last 12 messages)和max 8 iterations是好的防护措施,但可进一步优化:对于确定性高的场景(FQN完整、方法名明确),直接执行工具调用不经过LLM决策 + +--- + +### 2.5 系统架构 + +**Shell方案:** +``` +run_profiler.sh + ├── 1_ai_sampler.sh # Trace采集 + ├── 2_trace_filter.py # SQL特征提取 + └──

**SI** | +| 实时反馈 | 无 | 进度条 + 工具调用展示 | **SI** | + +**SI可借鉴:** +1. **Headless/CI模式**:参考Shell方案的"一条命令全流程"设计,为SI增加非交互模式。例如 `smartinspector --headless --package com.example.app --duration 10` 直接完成采集→分析→报告,适合CI/CD集成 +2. **输出标准化**:Shell方案的输出是一个完整的Markdown文件,可直接作为测试报告。SI的报告已很完善(含header tables + 问题列表),可增加机器可读的JSON输出选项,方便CI系统解析 + +--- + +## 三、SI可借鉴的改进点汇总 + +按优先级排序(P0=高优先级,P1=中优先级,P2=低优先级): +

**改进**:对于FQN完整、方法名明确的场景(非匿名内部类、非模糊匹配),直接用Python代码执行Glob→Grep→Read,不经过LLM决策 +- **价值**:减少50%+的token消耗和响应时间 +- **实现**:在 `_search_group()` 前增加确定性搜索判断 + ```python + if all(issue.get("search_type") == "java" and "$" not in issue["class_name"] for issue in group): + results = _deterministic_search(group, file_cache) + if all(r["reason"] == "found" for r in results): + return results # 跳过LLM + ``` + +#### 3. Headless/CI模式 — 一条命令完成全流程 +- **现状**:SI只支持交互式REPL +- **改进**:增加CLI参数 `--headless`,跳过交互直接执行 full pipeline +- **价值**:适合CI/CD集成和批量测试 + +### P1:体验和完整性提升 + +#### 4. 依赖引用搜索 — 扩展源码上下文 +- **现状**:Attributor只搜索目标类的方法体 +- **改进**:Read目标文件后,提取import列表中的项目内类和XML布局ID,一并搜索 +- **价值**:为AI诊断提供更完整的上下文,提升诊断准确度 +- **实现**:在Attributor Agent的Read后增加一步"关联分析" + +#### 5. package_list冷启动支持 +- **现状**:SI依赖 `process` 表获取包名,冷启动场景可能匹配失败 +- **改进**:在包名匹配失败时,fallback到 `package_list` 表反查 +- **价值**:支持冷启动性能分析场景 +- **实现**:修改 `pull_trace_from_device` 确保config包含 `linux.process_stats`,在 `collect_view_slices` 中增加 `package_list` fallback + +#### 6.

State distribution used overwrite instead of accumulation: when multiple raw states mapped to the same normalized name (e.g. R and R+ both → Running), the second would overwrite the first instead of summing. This caused incorrect percentages when both R and R+ appeared. 2. S+ state was not mapped to Sleeping: S+ (interruptible sleep, preemptible) is common in Android apps but was left as-is instead of being normalized to "Sleeping". Added comprehensive tests for normalization, overlap calculation, and filter conditions.

P1-5: Add package_list cold-start fallback — new _resolve_target_process() method tries process table first, falls back to package_list table for UID lookup when process table is empty during cold start. Annotates view_slices with target process info and includes resolved process in metadata. P1-6: Add SELinux cat-pipe bypass — when stdin-pipe perfetto config fails, fallback to pushing config file and using cat pipe (cat config | perfetto -c -). P1-7: Add perfetto collection auto-degradation — when config mode fails entirely, degrade to simpler cmdline mode with just atrace categories.

When a thread runs CPU-bound code without context switches, no new `sched_switch` fires, so the table incorrectly inherits the last state (typically `S`/Sleeping). The `__intrinsic_thread_state` table has the same underlying data but includes additional fields (`blocked_function`, `waker_utid`, `io_wait`) that provide actionable blocking context. + +### Reporter Truncation + +Content exceeding `SI_REPORT_MAX_TOKENS` (default 4000) is truncated at paragraph (`\n\n`) boundaries.

`collect_thread_state()` 在 `__intrinsic_thread_state` 主路径中,对每个 slice 单独执行一次 SQL 查询(per-slice loop, `collector/perfetto.py:1264-1278`),且每次还需要额外查询 waker name(`collector/perfetto.py:1317-1324`)。20 个 slice 最多产生 20 + 20 = 40 次 SQL 查询。 + +**影响范围**: `collector/perfetto.py:1203-1338` + +**具体方案**: + +1. 将 per-slice 查询改为批量 CTE 查询,一次 SQL 获取所有 slice 的 thread_state 分布: + +```sql +WITH slices AS ( + SELECT name, ts, dur, ts + dur AS end_ts + FROM slice + WHERE name LIKE 'SI$%' AND dur > 1000000 + ORDER BY dur DESC LIMIT 20 +) +SELECT + s.name AS slice_name, + its.state, + SUM(its.dur) AS total_ns, + its.blocked_function, + its.io_wait, + its.waker_utid +FROM slices s +JOIN __intrinsic_thread_state its + ON its.utid = :main_utid + AND its.ts < s.end_ts + AND its.ts + its.dur > s.ts +GROUP BY s.name, its.state, its.blocked_function, its.io_wait, its.waker_utid +ORDER BY s.name, total_ns DESC +``` + +2. waker name 批量解析:收集所有 unique `waker_utid`,一次查询获取所有 name。 + +**预估收益**: SQL 查询次数从 ~40 降低到 2(主查询 + waker 批量查询),thread_state 分析耗时减少 80%+。 + +**实施复杂度**: 中等。需要重构 Python 端的结果聚合逻辑。 + +### P2-2: `_walk_call_chain` 的逐行查询 + +**问题描述**: `perfetto.py:2104-2133` 中的 `_walk_call_chain` 对每个 parent_id 单独执行 SQL 查询,最深 20 层。在 `query_frame_slices` 中最多 10 个 slice 调用,总计可能 200 次 SQL 查询。 + +**影响范围**: `collector/perfetto.py:2104-2133` + +**具体方案**: 预加载所有相关 slice 到内存 map,然后在 Python 中遍历 parent 链(与 `collect_view_slices` 中 `_build_chain` 的做法一致)。 + +```python +def _walk_call_chain_cached(tp, slice_id: int, slice_map: dict, seen: set) -> dict: + """Walk call chain using pre-loaded slice map.""" + chain_items = [] + current_id = slice_id + for _ in range(20): + if current_id is None or current_id in seen or current_id not in slice_map: + break + r = slice_map[current_id] + seen.add(current_id) + chain_items.append({...}) + current_id = r.get("parent_id") + ... +``` + +在 `query_frame_slices` 中,先一次性查询所有涉及的 slice(按 parent_id 递归),构建 map,然后遍历。 + +**预估收益**: `query_frame_slices` 中 SQL 查询从 ~200 降低到 ~5。 + +**实施复杂度**: 低。 + +### P2-3: PerfSummary.to_json() 的重复 JSON 序列化 + +**问题描述**: `PerfSummary.to_json()` 使用 `json.dumps(self.__dict__, indent=2)`。随后在 `collector_node` 中,这个 JSON 字符串又在 `formatter.py` 中被 `json.loads()` 解析,又被 `deterministic.py` 中的 `compute_hints` 再次 `json.loads()`。同一段数据被反复序列化/反序列化 3-4 次。 + +**影响范围**: `collector/perfetto.py:80-81`, `graph/nodes/reporter/__init__.py`, `graph/nodes/reporter/formatter.py`, `agents/deterministic.py` + +**具体方案**: 在 pipeline 内部传递 `dict` 而非 JSON 字符串,仅在边界(state 存储和 LLM prompt 输入)进行 JSON 序列化。 + +- `PerfettoCollector.summarize()` 返回 `dict` 而非调用 `to_json()` +- `collector_node` 存储到 state 时序列化一次 +- `formatter.py` 和 `deterministic.py` 直接接收 `dict` + +**预估收益**: 减少不必要的 CPU 消耗和内存分配,对大 trace 尤为明显。 + +**实施复杂度**: 中等。需要修改 state 中 `perf_summary` 的类型约定。 + +### P2-4: LLM token 效率 - perf_analyzer 截断策略 + +**问题描述**: `perf_analyzer.py:49` 将 `perf_json[:3000]` 截断后发送给 LLM,但 `compute_hints` 已经预计算了所有结论。原始 JSON 仅作为"参考"出现,3000 字符的限制过于武断,可能截断关键数据(如 thread_state),也可能包含大量无用数据(如 cpu_idle_samples 的时间序列)。 + +**影响范围**: `agents/perf_analyzer.py:46-49` + +**具体方案**: 根据 `hints` 的内容智能选择补充数据,而非盲截。例如: +- 如果 `_classify_severity` 输出非空,附上 view_slices 的 slowest_slices +- 如果 `_analyze_thread_state` 输出非空,附上 thread_state 完整数据 +- 始终附上 frame_timeline 汇总(FPS, jank count) + +**预估收益**: LLM 输入 token 减少 30-50%(去掉无用的时间序列数据),同时分析质量提升(保留关键数据)。 + +**实施复杂度**: 低。 + +### P2-5: reporter 重复调用 compute_hints + +**问题描述**: `compute_hints(perf_json)` 在 pipeline 中被调用两次: +1. `perf_analyzer.py:43` — analyzer 阶段 +2. `formatter.py:17` — reporter 阶段(通过 `format_perf_sections`) + +同一段 JSON 被解析和计算两次,完全浪费。 + +**影响范围**: `agents/perf_analyzer.py:43`, `graph/nodes/reporter/formatter.py:17` + +**具体方案**: 将第一次 `compute_hints` 的结果存入 state(新增 `perf_hints` 字段),reporter 直接复用。 + +**预估收益**: 避免重复 JSON 解析 + 6 个分析函数的重复计算。 + +**实施复杂度**: 低。 + +--- + +## 3. 架构改进建议 + +### A1: SQL 注入风险修复 + +**当前问题**: 多处 SQL 查询使用 f-string 拼接用户可控输入: + +- `collector/perfetto.py:130`: `WHERE name = '{package_name}'` +- `collector/perfetto.py:149-153`: `WHERE package_name = '{package_name}'` +- `collector/perfetto.py:166`: `WHERE uid = {uid}` +- `collector/perfetto.py:743`: `WHERE id IN ({id_list})` +- `collector/perfetto.py:965-971`: track_id IN 查询 +- `collector/perfetto.py:1183-1199`: thread_state 多处 f-string + +虽然 Perfetto trace_processor 是本地进程且数据来自设备 trace,不涉及网络攻击面,但 `package_name` 和 `target_process` 来自 CLI 输入/WS 配置,理论上有注入可能。 + +**目标架构**: 使用参数化查询或至少进行输入验证。 + +**迁移路径**: +1. 在 `PerfettoCollector.__init__` 中验证 `target_process` 格式(仅允许 `[a-zA-Z0-9._]`) +2. 对于 `id_list` 类查询,确保所有 ID 都是整数(`int()` 转换) +3. 对于 `utid` 等,已在内部生成,风险较低,但仍建议使用占位符 + +**风险评估**: 低风险修改,不影响功能。 + +### A2: TraceProcessor 资源管理 + +**当前问题**: `query_frame_slices()` (`collector/perfetto.py:1934-2039`) 创建了 `TraceProcessor` 实例并在 `finally` 中 close,这是正确的。但 `PerfettoCollector` 的 `_open()` 方法只在 `close()` 中释放,而 `summarize()` 调用链中如果中途异常,`_tp` 可能不会被关闭。 + +更重要的是,`PerfettoCollector` 用作 context manager 时如果 `summarize()` 抛异常(如 `collect_cpu_hotspots` 失败),`__exit__` 能正确清理。但在 `collector_node` 中(`graph/nodes/collector.py:184`): + +```python +collector = PerfettoCollector(trace_path, target_process=target_process) +summary = collector.summarize() +``` + +没有使用 `with` 语句,`close()` 从未被调用。这意味着 `trace_processor_shell` 子进程在 `summarize()` 完成后仍然运行。 + +**目标架构**: 使用 context manager 确保资源释放。 + +**迁移路径**: +```python +with PerfettoCollector(trace_path, target_process=target_process) as collector: + summary = collector.summarize() +``` + +**风险评估**: 安全修改,`summarize()` 内部的 try/except 已保证即使异常也有结果返回。 + +### A3: 统一 LLM 实例管理 + +**当前问题**: LLM 实例分散在多处,管理模式不一致: + +| 位置 | 模式 | 问题 | +|------|------|------| +| `orchestrator.py:39-47` | 全局 `_route_llm` | 单例,但被 reporter 的 `generate_report` 复用(不合理) | +| `attributor.py:100-130` | 全局 + Lock + 探测 | `_structured_ok` 全局变量,线程不安全 | +| `perf_analyzer.py:17-25` | 全局 + Lock | 独立实例 | +| `frame_analyzer.py:21-29` | 全局 + Lock | 独立实例 | +| `explorer.py:19-33` | 全局 + Lock | `create_agent` API(可能已废弃) | +| `android.py:16-31` | 全局 + Lock | 同上 | + +**目标架构**: 创建 `LLMFactory` 类集中管理 LLM 实例。 + +```python +# config.py 或新的 llm_factory.py +class LLMFactory: + _instances: dict[str, ChatOpenAI] = {} + _lock = threading.Lock() + + @classmethod + def get(cls, role: str = "default", **kwargs) -> ChatOpenAI: + key = f"{role}:{frozenset(kwargs.items())}" + if key not in cls._instances: + with cls._lock: + if key not in cls._instances: + cls._instances[key] = ChatOpenAI(**get_llm_kwargs(role=role, **kwargs)) + return cls._instances[key] +``` + +**迁移路径**: 逐个替换现有全局变量。注意 `attributor.py` 的 `_structured_ok` 探测逻辑需要特殊处理。 + +**风险评估**: 低风险,但需要测试各 LLM 实例的 temperature/max_tokens 配置是否保持一致。 + +### A4: agent 层 API 不一致 + +**当前问题**: +- `explorer.py:36` 和 `android.py:16` 使用 `langchain.agents.create_agent` — 这个 API 在 LangChain 中可能已废弃或不存在于当前版本 +- `attributor.py` 使用手动的 tool-call loop(`llm.bind_tools` + 手动 dispatch) +- `perf_analyzer.py` 和 `frame_analyzer.py` 使用单次 `llm.invoke` + +三种不同的 agent 实现模式增加了维护负担。 + +**目标架构**: 统一使用 `llm.bind_tools` + 手动 dispatch 模式(attributor 的模式已被验证最可控),或统一使用 LangGraph 的 `create_react_agent`。 + +**迁移路径**: 长期演进。当前优先修复 `create_agent` 的导入问题。 + +**风险评估**: 中等。需要验证 LangChain 版本兼容性。 + +### A5: 缺少 `@node_error_handler` 的节点 + +**当前问题**: 以下节点缺少 `@node_error_handler` 装饰: + +- `graph/nodes/collector.py:107` — `collector_node`: 内部有 try/except 但不返回 `_pass_through` 字段,可能导致下游节点读到空值 +- `graph/nodes/attributor.py:33` — `attributor_node`: 完全没有异常处理 +- `graph/nodes/reporter/__init__.py:21` — `reporter_node`: 完全没有异常处理 + +这意味着如果这些节点抛出未预期的异常,LangGraph 会直接终止整个 pipeline,用户看到的是原始 traceback 而非友好错误信息。 + +**目标架构**: 所有 graph node 使用 `@node_error_handler` 装饰。 + +**迁移路径**: 逐个添加装饰器,确保每个节点的异常都被捕获并转换为 AIMessage。 + +**风险评估**: 低风险。 + +### A6: bridge_server 全局状态管理 + +**当前问题**: `bridge_server.py:314-317` 使用模块级全局变量管理状态: + +```python +_active_bridge: BridgeServer | None = None +_active_trace_server = None +_cached_perf_summary: str = "" +_cached_attribution_result: str = "" +``` + +`start_bridge()` 中还局部变量覆盖了这些全局(`_perf_summary_cache` vs `_cached_perf_summary`),容易混淆。 + +**目标架构**: 将状态封装到 `BridgeManager` 类中,或至少统一变量命名。 + +**迁移路径**: 短期:统一变量命名。长期:封装到类。 + +**风险评估**: 低风险。 + +--- + +## 4. 可靠性改进 + +### R1: TraceProcessor 连接超时处理 + +**问题**: `PerfettoCollector._open()` (`collector/perfetto.py:100-108`) 设置了 `load_timeout=10` 秒,但没有重试机制。对于大 trace 文件(>100MB),首次加载可能超时。 + +**方案**: 添加重试逻辑,或根据文件大小动态调整超时。 + +```python +def _open(self) -> TraceProcessor: + if self._tp is not None: + return self._tp + file_size_mb = Path(self.trace_path).stat().st_size / 1024 / 1024 + timeout = max(10, int(file_size_mb / 10)) # 100MB -> 10s, 1GB -> 100s + config = TraceProcessorConfig(bin_path=self.shell_path, load_timeout=timeout) + self._tp = TraceProcessor(trace=self.trace_path, config=config) + return self._tp +``` + +**文件**: `collector/perfetto.py:100-108` + +### R2: WS 连接断开后的状态同步 + +**问题**: `ws/server.py:278-283` 的 `_handler` 在连接关闭时从 `_connections` 中移除,但没有清理 `_pending_acks`。如果 app 在 ACK 到达前断开,等待 ACK 的线程会永久阻塞直到 timeout。 + +**方案**: 在连接关闭时,set 所有 pending acks(标记为失败)。 + +```python +async def _handler(self, ws) -> None: + self._connections.add(ws) + try: + async for raw in ws: + ... + except websockets.exceptions.ConnectionClosed: + pass + finally: + self._connections.discard(ws) + # Release any pending ACKs for this connection + for msg_id, event in list(self._pending_acks.items()): + if not event.is_set(): + event.set() # Will return False from send_config/send_start_trace +``` + +**文件**: `ws/server.py:264-283` + +### R3: attributor 的 `_structured_ok` 竞态条件 + +**问题**: `attributor.py:55` 的 `_structured_ok` 是模块级全局变量,在 `_get_llm()` 中初始化,在 `_search_group()` 中修改为 `False`。如果有两个 attributor 调用并发执行(虽然当前 CLI 是单线程),一个修改 `_structured_ok` 可能影响另一个。 + +**当前风险评估**: 低。CLI 是单线程调用 attributor,但 frame_analyzer 的 bridge_server 调用在 executor 线程中,理论上可能并发。 + +**方案**: 将 `_structured_ok` 移入 `_get_llm()` 的 Lock 保护范围内,或在初始化时一次性探测并缓存。 + +**文件**: `agents/attributor.py:55, 863` + +### R4: subprocess 资源泄漏 + +**问题**: `TraceServer` (`collector/perfetto.py:1877`) 使用 `Popen` 启动 `trace_processor_shell`,如果 BridgeServer 异常退出,`TraceServer.stop()` 可能不被调用。`bridge_server.py:419-427` 的 `stop_bridge()` 虽然会清理,但依赖调用方正确调用。 + +**方案**: 为 `TraceServer` 添加 `__del__` 方法作为最后保障,或使用 `atexit` 注册清理。 + +```python +import atexit + +class TraceServer: + def __init__(self, ...): + atexit.register(self.stop) +``` + +**文件**: `collector/perfetto.py:1848-1919` + +### R5: JSON 解析失败的静默吞没 + +**问题**: 多处 `json.loads()` 在 try/except 中静默吞没错误,返回空值: + +- `perf_analyzer.py:46`: `compute_hints` 内 `json.loads` 失败返回 `""` +- `formatter.py:22`: `json.loads` 失败返回 `{}` +- `frame_analyzer.py:79`: `json.loads` 失败截断到前 2000 字符 + +这些静默失败可能隐藏重要错误,使得调试困难。 + +**方案**: 至少用 `logger.warning` 记录解析失败,不要完全静默。 + +**文件**: 多处 + +### R6: node_error_handler 中的 print + +**问题**: `graph/state.py:78` 的 `node_error_handler` 使用 `print()` 输出错误信息,而非 `logger.error()`。按照项目的 logging 标准,应该使用 logger。 + +```python +# 当前 +print(f" [{node_name}] ERROR: {e}", flush=True) + +# 应改为 +import logging +logging.getLogger(__name__).error("[%s] %s", node_name, e) +``` + +**文件**: `graph/state.py:78` + +--- + +## 5. 代码质量改进 + +### Q1: extract_class / extract_method 的重复解析模式 + +**问题**: `commands/attribution.py` 中 `extract_class()`, `extract_method()`, `extract_fqn()` 三个函数对同一个 SI$ tag 分别解析一次,且解析逻辑高度重复(每個函数都有相同的 `if body.startswith("block#"):` 等分支)。 + +**方案**: 创建统一的 `_parse_si_tag()` 函数,一次解析返回结构化结果: + +```python +@dataclass +class SITag: + tag_type: str # "block", "RV", "inflate", "view", "handler", ... + class_name: str + method_name: str + fqn: str + search_type: str # "java", "xml", "system" + raw_name: str + +def parse_si_tag(name: str) -> SITag: + """Single-pass SI$ tag parser.""" + ... +``` + +**文件**: `commands/attribution.py:15-401` + +### Q2: formatter.py 中 import 放在函数内部 + +**问题**: `graph/nodes/reporter/formatter.py:17` 在函数内部 `from smartinspector.agents.deterministic import compute_hints`,每次调用都执行 import 查找(虽然 Python 会缓存)。 + +**方案**: 移到文件顶部。如果存在循环依赖问题,说明模块拆分不合理。 + +**文件**: `graph/nodes/reporter/formatter.py:17`, `agents/perf_analyzer.py:42` + +### Q3: SIServer 单例模式的可测试性 + +**问题**: `ws/server.py` 的 `SIServer` 使用类级 `_instance` 和 `_lock` 实现单例。这使得单元测试难以注入 mock server。 + +**方案**: 添加 `reset()` 类方法用于测试,或使用依赖注入。 + +**文件**: `ws/server.py:58-63` + +### Q4: 测试覆盖 + +**问题**: 项目目前没有测试文件(`tests/` 目录为空或不存在)。 + +**建议的测试优先级**: + +1. **P0**: `commands/attribution.py` 的 SI$ tag 解析 — 纯函数,容易测试,覆盖最核心的业务逻辑 +2. **P0**: `agents/deterministic.py` 的 `compute_hints` — 纯函数,验证预计算逻辑正确性 +3. **P1**: `collector/perfetto.py` 的 SQL 查询逻辑(用 mock TraceProcessor) +4. **P1**: `graph/state.py` 的 `_pass_through` 和 `node_error_handler` +5. **P2**: 各 graph node 的输入/输出契约 + +### Q5: 代码重复 — block stack trace 关联 + +**问题**: `collect_block_events()` (`collector/perfetto.py:1169-1201`) 和 `_correlate_block_stacks_from_logcat()` (`collector/perfetto.py:2042-2101`) 实现了几乎相同的 bisect-based 时间戳关联逻辑。 + +**方案**: 提取公共函数 `_correlate_by_timestamp(sql_events, log_entries, match_window_ns)`。 + +**文件**: `collector/perfetto.py:1169-1201` 和 `collector/perfetto.py:2042-2101` + +### Q6: config.py 的 get_* 函数重复模式 + +**问题**: `config.py` 中 `get_tool_timeout()`, `get_read_max_lines()`, `get_read_max_bytes()`, `get_read_max_line_length()`, `get_report_max_tokens()`, `get_ws_ping_timeout()` 六个函数完全同构: + +```python +def get_xxx() -> int: + try: + return int(os.environ.get("SI_XXX", default)) + except (ValueError, TypeError): + return default +``` + +**方案**: 提取 `_env_int(key, default)` 辅助函数。 + +```python +def _env_int(key: str, default: int) -> int: + try: + return int(os.environ.get(key, str(default))) + except (ValueError, TypeError): + return default + +def get_tool_timeout() -> int: + return
