W16: close CRITICAL/HIGH findings, integrate metadata gate, complete audit summaries (W16.1-W16.6)
- W16.1 (曹武): F-11.7-1 CLOSED — confirmed W12.4 fix, corrupt binary eliminated
- W16.2 (孙宇): F-11.1-1 FIXED — context_plugin.cpp try/catch on set_max_tokens + on_shutdown
- W16.3 (陈风): F-11.1-2 CLOSED — confirmed W12.1 fix, strdup OOM protection already in place
- W16.4 (胡桐): Integrate check_agents_metadata into refresh_status.py as pre-gate (error→exit 1)
- W16.5 (周岩): Add Findings Summary to W13.3 network audit, register 3 findings
- W16.6 (赵码): Add Findings Summary to W13.1+W13.2 AI audits, register 8 findings (4 already W14-fixed)

Build 0 error, ctest 4/4 pass, metadata check 0 error 0 warning.

engineer-sun 孙宇 工程师 灵活敏捷,擅长跨技术栈整合,乐于做"胶水"工作 5年开发经验技术栈以 Python/Rust/C++ 为主。 熟悉 LSP 协议、tree-sitter、JSON-RPC做过编辑器插件。 偏好:能复用就不重写。 务实,喜欢列协议字段
LSP / JSON-RPC
协议解析
Rust + C++ 互操作
编辑器集成
对 ABI 稳定性细节理解尚浅
文档写得偏简

2026-05-27 W6.1: 修复 LSP reader_loop 协议合规 bugContent-Length 状态机解析) completed 将 reader_loop 改为状态机模式读取 header 块:循环 read_line 直到空行, 累积 Content-Length遇到其他 header如 Content-Type不丢弃。 修复前:第一行非 Content-Length 时 continue 丢弃该行,导致 header 解析偏移错位。 修复后:正确遍历所有 header 行,空行后若仍未找到 Content-Length 则记录错误并跳过帧。 编译通过smoke test 通过。

2026-05-27 W13.2: 深度审计 deepseek_plugin.cpp (486 行) — SSE 解析/ABI 异常安全/堆纪律/重复度 completed SSE 解析: catch(...) 全面兜底,不 crash[DONE] sentinel 精确匹配脆弱。 核心发现7 个 C ABI 入口均无 try/catch畸形 tools_json → json::parse 异常 → std::terminate()。 跨 DLL 堆/字符串生命周期 A 级合规;与 anthropic ~55% 重复,~230 行可抽取为 ai_plugin_base。 综合评级 C+。报告写入 agents/audits/W13.2-deepseek-audit.md。

2026-05-27 W14.2: 修复 lsp_plugin.cpp 致命死锁 (W13.4 审计发现) + vtable 异常包装 completed 死锁修复 (Option C — 拆分 stop_locked/stop 双版本): - 原问题: g_lsp_impl_start L534 持 g_lsp.mutex (非递归) 调用 g_lsp_impl_stop, 后者 L570 再次 unique_lock 同 mutex → 自死锁。 - 修复: 拆分 g_lsp_impl_stop_nolock() (无锁体) + g_lsp_impl_stop() (公开接口) + g_lsp_impl_stop_locked(lock) (持锁调用者先 unlock 再 delegate _nolock)。 - timeout 路径 L541 改为 g_lsp_impl_stop_locked(lock) — 明确 invariant: lock 在调用点释放, _nolock 内部自行加锁。 异常安全包装 (try/catch 双层, 符合 plugin-abi.md §8): - 7 个 service vtable: start / stop / open_document / close_document / get_diagnostics / get_hover / get_completion - reader_loop: while 循环体入 try, 异常后仍设 running=false + notify_all 防 waiter 永久阻塞 - handle_message: 全函数体入 try - on_shutdown: 全函数体入 try, 异常后仍置 g_host=nullptr - int 返回函数: catch → -1; char** 返回函数: catch → *json_out=nullptr, return -1; void 函数: catch → 仅 log。 构建验证: cmake --build Release 0 error; ctest 4/4 pass。 L420-471 reader_loop, L481-559 start, L561-603 stop 三件套, L605-630 open, L632-655 close, L657-683 diagnostics, L685-730 hover, L730-780 completion, L807-821 on_shutdown.

2026-05-27 W16.2: 修复 F-11.1-1 — context_plugin.cpp C++ 异常穿越 ABI 边界 completed 为 context_set_max_tokens (L319-329) 和 on_shutdown (L370-384) 添加 try/catch 包装。 void 函数模式: catch → 仅 log (g_host->log)。trim_impl / context_count_tokens / context_trim / on_init 已在 W12.1 预制异常保护,本次补全剩余 2 个入口。 构建验证: cmake --build Release 0 error; ctest 4/4 pass。 findings-registry: F-11.1-1 → FIXED, Fix Wave W16.2。
