- 客机三分（chv-guest/chv-daemon.py、chv-execd.py、chv-syncd.py， 仅标准库；systemd Restart=always；build.sh 拷入 + 单元 + enable； buildinfo/check/generate lockfile 登记）： daemon=心跳/资源上报/快照配合（prepare-snapshot 问 execd， 有运行中任务或联系不上即拒绝）；execd=shell/文件读写/codex 托管（chv-cell 起 host.py，setsid 脱离，任务登记落盘， 重启按 pid 认领；SO_PEERCRED 只认 uid 0/1000；codex env 白名单）；syncd=常驻循环只调 chv-sync pull/push，规则一条 不改（先 pull --ff-only 再 push，分叉即停、不 --force、 不 rebase；仓不存在记 needs-boot 不擅自 clone）。 host.py 仍是唯一任务/codex 引擎，broker/browser/cell 分工 不变，不另起第二套 agent。 - 阶段 1 遗留修复：restore_vm 失败路径 stop_vm(keep_disk=True)， seed.iso 与任务盘都留，重试有输入；vm.boot/restore 的 tap 触点遇 Resource busy 等 tap 空闲后重试一次（_wait_tap_idle 看 ip link state，_ch_remote 报错带 stderr 尾巴以便识别）； 诊断不用 pgrep -x（15 字符上限）。 - 单测 cloud/tests/test_chv_opt_stage2.py 25 项；P2 干跑夹具 与 enable 行断言随构建接线更新。 - 全量 cloud/tests 2001 全过（skipped=8）。

"""生成 CHV 客机镜像的 BUILDINFO.json（build.sh 调用）。
|
||
|
||
从 build.sh 抽出（B-02），使其可独立单元测试。输入全部是
|
||
已落盘的构建产物与读回文件，不编造版本号：versions 来自
|
||
客机读回的 dpkg-query / pip freeze（Playwright=1 时另有
|
||
ms-playwright 缓存目录名作 chromium 标识）；artifacts 的
|
||
sha256/size 是对产物文件实测的；image_sha256 即 disk.raw
|
||
的 sha256，供 generate_lockfile.py 沿用。
|
||
|
||
用法：
|
||
python3 buildinfo.py OUT_DIR TAG UBUNTU CODEX_VERSION \\
|
||
REPO_COMMIT UBUNTU_IMAGE_SHA256 PLAYWRIGHT(0|1)
|
||
[CHROMIUM_HEADLESS_SHELL_REV]
|
||
|
||
CHROMIUM_HEADLESS_SHELL_REV（可选，纯数字）：钉死的
|
||
ms-playwright 缓存修订号（如 1248）。PLAYWRIGHT=1 且
|
||
给了该值时，versions.chromium 里须恰好出现
|
||
chromium_headless_shell-<rev>，否则退出 1、构建失败；
|
||
未给时只记录、不强制，BUILDINFO.chromium_pinned_rev
|
||
记 null，构建输出由 build.sh 明说“未钉死”。
