W14 addresses the five most critical findings from the W13 plugin audits: - W14.1 network: enable ssl::verify_peer + SSL_set1_host SNI hostname verification (fixes TLS bypass, W13.3 CVSS 7.4); add steady_timer DNS timeout and bottom-up catch(...) hardening (engineer-zhou) - W14.2 lsp: fix reader_loop/stop mutex deadlock via stop_nolock/stop_locked split (W13.4); wrap 11 vtable/entry functions in try/catch with cv notification on reader exit (engineer-sun) - W14.3 tools: add is_safe_path() rejecting empty/absolute/.. paths before file_io calls (fixes path traversal, W13.5 CVSS 7.5); guard g_tools and g_session/g_history under mutex; 9 vtable try/catch (security-cao) - W14.4 host: add fallback plugin search (../plugins/) so binaries run from build/tests/ load current DLLs, resolving the W13.6 R2 stale-DLL false alarm (architect-lin) - W14.5 anthropic+deepseek: wrap 12 ABI boundary functions in try/catch with log-guard, preventing exceptions from crossing the C ABI (engineer-chen) Verified: cmake build 0 error 0 warning, ctest 4/4 pass, smoke R2 now passes naturally.

role: 工程师
|
||
personality: 安静专注，擅长长时间处理复杂调试任务，有"慢思考"习惯
|
||
background: |
|
||
9年系统编程经验，主要在 Linux 内核驱动和用户态高性能服务。
|
||
熟悉 epoll/io_uring、Boost.Asio、协程 (C++20 coroutines)。
|
||
偏好：先用 strace/perf 量化，再改代码。
|
||
communication_style: 数据驱动，每次结论都附 benchmark
|
||
strengths:
|
||
- 异步 IO / 协程
|
||
- 性能 profiling
|
||
- Linux 系统调用
|
||
- 网络协议 (HTTP/2, WebSocket)
|
||
weaknesses:
|
||
- 在 Windows 平台不如 Linux 熟练
|
||
- 有时陷入过度优化

event: "W12.1 - context_plugin 三处 bug 修复 (W11.1 audit)"
|
||
detail: |
|
||
修复项: (1) C++ 异常穿越 ABI: trim_impl/context_count_tokens/context_trim/on_init 包裹 try/catch, 异常时 int 返回 -1, size_t 返回 0. (2) strdup null check: 引入 strdup_message_fields() + free_msg_strs() 辅助函数, 两处循环逐一检查返回值, OOM 时回滚已分配字段. (3) g_max_tokens 死变量: 选项A — trim_impl max_tokens==0 时用全局值; 结果组装前按 ceil(g_max_tokens/100) 裁剪消息数（粗略 ~100 token/msg）.
|
||
编译 0 error 0 warning, ctest 4/4 pass.

event: "W5.1 - network_plugin SSE 改 buffer_body"
|
||
detail: |
|
||
do_post_stream response parser: http::string_body -> http::buffer_body.
|
||
消除 parser 完整 body + fragment + result_body 三份冗余。
|
||
编译 0 error 0 warning, smoke test 通过.
|
||
峰值内存: -67% (~360KB -> ~120KB), 无额外拷贝.
|
||
留待真实 API 压测验证 end-to-end.

event: "W14.1 - network_plugin TLS/DNS/exception 三修复 (W13.3 audit)"
|
||
detail: |
|
||
修复 W13.3 审计三个问题:
|
||
(1) TLS 证书验证 (CVSS 7.4): HttpClientCtx 构造添加 set_verify_mode(verify_peer);
|
||
handshake 前 SSL_set1_host 启用 hostname 验证; SNI/hostname-fail / handshake-fail
|
||
均 host_log(ERROR).
|
||
(2) DNS resolve 超时: 用 steady_timer + async_wait + resolver.cancel() 实现 10s 超时,
|
||
超时/失败均返回明确错误码.
|
||
(3) catch(...) 兜底: 在 catch(const std::exception&) 后追加 catch(...),
|
||
非 std 异常不再穿越 C ABI (对齐 plugin-abi.md §8).
|
||
编译 0 error 0 warning, ctest 4/4 pass.
|
||
无新增依赖. Windows 上 set_default_verify_paths 可能找不到系统 CA, 已加 TODO
|
||
建议设置 SSL_CERT_FILE 或 bundle cacert.pem.
