Stage C Step 3: DockerExecutor 集成 AgentLoop + web lifespan reaper
- core/executor_docker.py 新增 DockerExecutor:组合 HostExecutor+SandboxPool,
shell/run_python 走 docker exec(setsid + --user 1000:1000 + --workdir),
其他工具直通 host(§7.5 #6 信任域二分)
- run_python tmp .py 落 <user_root>/.zcbot_tmp/<task_id>/(dotfile,/v1/files
天然过滤),容器内对应 /workspace/.zcbot_tmp/...,跑完 unlink
- ZCBOT_SANDBOX_BACKEND=host|docker env 切 backend,默 host(Windows dogfood
零变化);docker 路径 pool 未 init → fail-fast 不静默退化
- web/app.py lifespan:docker backend 启动时 init_pool + shutdown_all 清孤儿 +
60s 后台 reaper(run_in_executor 调 sync reap_idle);关闭时 cancel + 兜底清
- pool.py 顺手清 Step 2 债:asyncio.Lock → threading.Lock,ensure 改同步
(主使用方是 BG 线程 tool call,ephemeral loop 会让 asyncio.Lock 跨锁失效)
- Cancel limitation 接受:Popen.kill() 仅杀 docker CLI 客户端,容器内进程靠
idle 5min reaper 兜底;升级到 PGID 协议(§7.5 #3)等用户反馈触发
- tests/test_executor_docker.py 11 测试覆盖关键路径(host 直通/argv 形态/
tmp 清理/timeout/cancel/未知工具/enable_run_python=False)
- DESIGN.md 不动(纯按 §7.5 #5 #6 既有协议实施)
- RUN.md 加 ZCBOT_SANDBOX_BACKEND env 段 + 切 docker 的前置条件 + 集成验证路径
- unittest discover 12/12 PASS
