background: |
4年 QA + 2年红队渗透经验。
熟悉内存安全工具 (ASan/UBSan/Valgrind/DrMemory)
做过多款桌面软件的稳定性测试。
偏好:能压就压崩,崩了再补。
communication_style: 简短粗犷,喜欢贴 stack trace
strengths:
- 破坏性测试 / 压力测试
- 内存安全工具链
- Windows 平台特化测试
- 崩溃分析 (WinDbg/gdb)
weaknesses:
- 单元测试有时过于针对实现
- 不太关注测试可读性

event: "W22.2: network_plugin 单元测试 — 7 测试块, 88 断言, 覆盖 parse_headers_json/SSE 解析/参数校验"
rating: done
detail: |
创建 tests/network_plugin_test.cpp (290 行), 通过 #include source 模式测试:
Block1 parse_headers_json 正常 JSON (13 断言)
Block2 空/null 输入 (5 断言)
Block3 畸形 JSON 边界 — 未闭合括号/引号/嵌套对象/二进制垃圾等 11 场景 (15 断言)
Block4 超长 header 值 — 5000/10000 char value, 1000 char key, 空 key (8 断言)
Block5 SSE 行解析 — LF/CRLF/空行/[DONE]/断帧/null bytes (23 断言)
Block6 http_post_json 参数校验 — nullptr host/port/target/body/response_body/status_code (10 断言)
Block7 http_post_stream 参数校验 (2 断言)
_exit() 绕过 OpenSSL 静态析构顺序问题; tests/CMakeLists.txt 新增 dstalk-network-plugin-test 目标

event: "W21.5: smoke 回归补 tool_calls 边界用例 — 4 测试块, 12 断言"
rating: done
detail: |
在 tests/smoke_test.cpp 新增 W21.5 边界测试块(行 563-658, +96 行):
W21.5-1 null tool_calls_json: add message 后验证 history+1 且字段为 nullptr (2 断言)
W21.5-2 空 "[]" tool_calls_json: add message 后验证 history+1 且字段保留为 "[]" (2 断言)
W21.5-3 有效 tool_calls mock: register_tool→execute 验证 handler 被调用(g_mock_tool_called==1), unregister 后返回 error (4 断言)
W21.5-4 save/load 往返: 含 tool_calls 消息的 session 经 save/load 后数据不丢失 (3 断言)
新增 mock 全局: g_mock_tool_called + mock_tool_handler (行 27-31)
cmake --build build --config Release 0 error, ctest 6/6 100% pass
- date: 2026-05-27
event: "W20.3: plugin_loader 安全回归测试 — 覆盖 W19 修复的 F-18.3-1~5"
rating: done
detail: |
创建 tests/plugin_loader_test.cpp (265行), 5 个测试块 32 条断言:
Block1 路径验证: nullptr/非法扩展名/..遍历/非plugins目录/无扩展名 → 全部返回 -1
Block2 合法路径+next_id_: 加载 build/plugins/ 下的 config/file-io 插件, ID 唯一且单调递增
Block3 并发原子性: 4 线程同时 load 不同 DLL, 所有 ID 去重后无重复
Block4 失败路径日志: mock host_api 验证 log 被调用 (ext 错误 + LoadLibrary 失败)
Block5 边界: 空 loader list_plugins→[], unload 无效 ID→-1, get_plugin 无效→nullptr
cmake --build build --config Release 0 error, ctest 6/6 100% pass
tests/CMakeLists.txt 新增 dstalk-plugin-loader-test 目标, 含 compiler define + boost_json.cpp

event: "W19.1: 修复 F-18.3-1 — plugin_loader 5 处 C ABI 调用点添加 try/catch (合作 security-cao)"
rating: done
detail: |
为 5 处 C ABI 调用点添加 try/catch(const std::exception&)+catch(...) 双层保护:
init_fn(L59)/on_init×2(L237,L272)/on_shutdown×2(L108,L306)。
initialize_all fail-continue: 单插件异常仅记录日志+跳过,不阻断其余插件加载。
shutdown_all/unload_plugin on_shutdown 异常仅 log 不阻断 DLL 卸载。
新增 host_api_ 成员统一日志通道fprintf→host_api->log。
编译 0 error + ctest 5/5 pass。findings-registry F-18.3-1→FIXED。

event: "W18.3: plugin_loader 安全审计 (合作 security-cao) — 9 维度审计, 1 HIGH + 4 MEDIUM + 3 LOW 发现"
rating: done
detail: |
联合审计 dstalk-core/src/plugin_loader.cpp + plugin_loader.hpp (385行)。
破坏性关注点: on_init/on_shutdown 五处 C ABI 调用无 try/catch → 单个插件 OOM 即可 std::terminate() 拖垮 host;
load_plugin 全路径静默失败, GetLastError/dlerror 不调用;
dstalk_plugin_load 公开 API 路径直传 LoadLibrary/dlopen 零验证, 相对路径触发 DLL 搜索劫持。
报告: agents/audits/W18.3-plugin-loader-audit.md。
findings-registry: F-18.3-1~5 录入 Open 分区。
