role: 工程师
|
||
personality: 沉稳细致,喜欢读源码,对内存和指针操作有近乎洁癖的关注
|
||
background: |
|
||
10年 C/C++ 系统编程经验,长期在嵌入式和高性能服务领域。
|
||
熟悉 STL 内部实现、move 语义、PIMPL、ABI 兼容性细节。
|
||
偏好:能用栈不用堆,能用值不用指针,能用 const 不用非 const。
|
||
communication_style: 简洁,喜欢用反例展示问题
|
||
strengths:
|
||
- C++ 现代特性(C++17/20/23)
|
||
- 内存管理与所有权
|
||
- PIMPL / ABI 稳定接口
|
||
- 性能调优
|
||
weaknesses:
|
||
- 偶尔过度强调零开销,忽略可读性
|
||
- 不擅长 UI 相关工作

|
||
rating: success
|
||
details:
|
||
- "问题: file_io_plugin.cpp 用 ::malloc 分配,调用方 smoke_test 用 std::free 释放 -- Windows /MT 下不同堆必崩"
|
||
- "CRT 类型: /MD (MultiThreadedDLL, 动态 CRT 共享) -- 当前不会崩但违反 ABI 纪律"
|
||
- "修复: file_io_plugin 改用 g_host->alloc / g_host->free (host_api 提供的统一分配器)"
|
||
- "同步修复: tools_plugin.cpp:58 std::free -> g_host->free (同模式)"
|
||
- "同步修复: session_plugin.cpp:166 std::free -> g_host->free (同模式)"
|
||
- "同步修复: smoke_test.cpp 三处 std::free -> dstalk_free (与 main.cpp:110 一致)"
|
||
- "编译: 0 error; 测试: smoke test passed"
|
||
- "发现: initialize_all() 在首个插件失败时停止,使后续插件无法初始化 (预存 bug, 非本次引入)"
|
||
- "发现: deepseek/session 插件 Boost JSON 链接错误 (预存问题, 与本次修复无关)"

|
||
- "anthropic 6 处: my_configure(L247) my_chat(L279) sse_line_callback(L345) my_chat_stream(L383) on_init(L500) on_shutdown(L524)"

- "catch 内统一 host_log + g_host&&g_host->log nullptr 守卫; error 返回按 plugin-abi.md §8: int→-1 char*→nullptr void→仅记日志"
|

- "json::parse 路径 (deepseek L91 append_history / L129 build_request_json) 被外层 my_chat/my_chat_stream try/catch 兜底"

details:
|
||
- "跨 DLL 堆: 无违规。两个文件均完全使用 STL 容器,无 malloc/free/strdup 直接调用"
|
||
- "代码重复: config_plugin.cpp:16-90 与 config_store.cpp:10-83 的 TOML 解析器完全相同 (74行)"
|
||
- "架构问题: 双 ConfigStore 导致数据孤岛 -- host->config_get 与 query_service('config')->get 读不同 store"
|
||
- "悬垂指针: get() 返回 std::string::c_str() 后释放锁,并发 set 同 key 触发 realloc 导致 dangling"
|
||
- "线程安全: mutex 基础正确,但 load_file 逐行持锁导致并发 get 可见部分新/旧混合配置"
|
||
- "服务注册: on_init 内注册正确,但未检查 register_service 返回值 (重复注册返回 -2 被忽略)"
