Summary

Remote SSH Host installed with CODEXHOST_DATA_DIR=~/.codexhost/remote/data while local Desktop uses ~/.codexhost. External harness threads and pins (Claude Code, Pi, Cursor CLI, …) therefore never appeared over SSH; only native Codex (from ~/.codex) showed up.

This PR adds an opt-in way to point Remote Host at the same data directory as local Desktop, without changing the default isolated layout.

Fixes #583

Changes

  • codexhost remote install --share-local-data → CODEXHOST_DATA_DIR=~/.codexhost
  • codexhost remote install --data-dir PATH → explicit override
  • Reinstall preserves a previously chosen shared/custom dataDirectory unless a new flag is passed
  • Uninstall still only removes ~/.codexhost/remote install bits; it does not delete a shared Desktop data directory
  • Docs (EN + zh-CN) explain the split and the new flags
  • Unit tests for install/CLI

Test plan

  • vitest remote-host-install.test.ts + remote-host-cli.test.ts (27 passed)
  • tsc -b packages/host-runtime
  • eslint on touched TS files
  • On a machine with local harness pins under ~/.codexhost, run codexhost remote install --share-local-data, reconnect via Remote SSH, confirm harness threads/pins appear
  • Confirm default install (no flag) still uses ~/.codexhost/remote/data
  • Confirm uninstall after --share-local-data leaves ~/.codexhost mapping-store intact

Notes

Hard-switching the default data dir was avoided to keep existing remote-only installs stable. Desktop UI wiring for the flag can follow; CLI/API is enough to unblock the reported gap.

Remote install defaulted CODEXHOST_DATA_DIR to ~/.codexhost/remote/data,
so local Desktop harness threads and pins under ~/.codexhost never
appeared over SSH. Add --share-local-data / --data-dir, preserve the
chosen path across reinstall, keep uninstall from deleting shared data,
and document the option.

Fixes BytePioneer-AI#583

核实结果:卸载逻辑不会删除位于安装目录内的自定义数据目录,因此该评论的前提不成立。

uninstallRemoteHost 只删除 wrapper 和 manifest,并尝试删除 bin 与安装根目录。删除安装根目录使用的是非递归的 rmdir。当目录内仍有自定义数据时,该调用会因 ENOTEMPTY 失败,错误会被忽略,目录和数据都会保留。

📝 Summary

Summary by CodeRabbit

  • 新功能
    • Remote SSH Host 默认使用独立数据目录;启用 --share-local-data 或指定与 Desktop 相同的 --data-dir 后,可在远程查看本机已有的会话和置顶内容。
    • 重新安装时会保留已选的数据目录,除非指定新目录;卸载不会删除 ~/.codexhost/remote 之外的共享数据。
    • 安装选项会检查缺失的目录参数,并拒绝同时指定 --share-local-data 和 --data-dir。
  • 文档
    • 补充默认隔离与共享存储的说明,以及会话不可见时的排查步骤。

Remote SSH Host 安装新增共享本地数据目录和指定数据目录的选项。未指定新选项时,重新安装沿用已有数据目录。中英文文档说明目录隔离、共享方式、会话可见范围及卸载行为。

Explanation

所有变更均与 #583 的需求相关:

  • CLI 参数解析(remote-host-cli.ts):新增 --share-local-data 与 --data-dir,并检查缺失值和冲突。这是 #583 要求的安装选项。
  • 安装逻辑(remote-host-install.ts):新增 dataDirectory 与 shareLocalData 解析,重装时保留共享路径。这对应 #583 的“保留选择”需求。
  • 目录权限处理:仅对安装管理的默认目录执行 chmod 0700,已有共享目录保留原权限。该变更用于避免收紧本机 Desktop 的 ~/.codexhost 权限,与共享目录直接相关。
  • 文档(EN 与 zh-CN)和单元测试:说明新选项、双端可见范围与排查步骤,并覆盖安装与 CLI 行为。

未发现与 #583 无关的变更。PR 描述说明 Desktop UI 不在范围内,且代码变更中未包含 UI 修改。

Full details: Linked Issues check

Explanation

适用需求来自直接关联的 #583。该 Issue 处于 open 状态,且是直接关联目标,因此其编码需求适用。

已确认的实现(基于 whole-PR diff,base 到 head):

  1. 新增安装选项 --share-local-data(remote-host-cli.ts)和 --data-dir PATH。resolvePaths 将 shareLocalData 映射为 ~/.codexhost,将 dataDirectory 映射为显式路径(支持 ~ 展开)。同时指定两者时报错。
  2. 重新安装保留已有共享或自定义目录。当未传入新选项时,installRemoteHost 使用 previousManifest.dataDirectory。
  3. 托管 profile 块读取 manifest.dataDirectory 并导出 CODEXHOST_DATA_DIR。因此共享路径会进入 Remote SSH 的运行环境。
  4. 默认安装(无选项)仍使用 &lt;installRoot&gt;/data,即 ~/.codexhost/remote/data。

未确认的需求:

  • 卸载时不删除共享的 ~/.codexhost 数据。本 PR 未修改卸载函数。现有卸载代码的删除目标未在已读取的证据中确认。基础版本中数据目录位于安装根目录内,因此无法判断卸载是否单独删除 manifest.dataDirectory。
  • 测试摘要中未包含卸载与共享目录的用例。

作者报告的 vitest、tsc、eslint 结果未由本评估独立复现。

Resolution

请确认卸载流程(remote-host-install.ts 中的卸载函数)删除的路径范围。若卸载会删除 manifest.dataDirectory,则共享 ~/.codexhost 会被删除,需要修正。若卸载仅删除安装根目录下的文件,请补充或指出覆盖 --share-local-data 后卸载的测试,以证明共享数据保留。

Reject --share-local-data together with --data-dir while parsing the
CLI, so the conflict is reported on every platform (the Windows CI run
hit the macOS/Linux install guard first). Also refuse an option in place
of an option value, expand a leading ~ in --data-dir, only chmod 0700 a
data directory that install created (or its own default directory), and
document restarting the remote service after switching data dir.

Pushed 441edcc to fix the windows-latest failure: the --share-local-data + --data-dir conflict is now checked while parsing CLI arguments, before installRemoteHost hits the macOS/Linux platform guard, so the test gets the same error on every platform. The same commit addresses the four CodeRabbit notes (option-as-value, ~ expansion, keep existing dir permissions, restart steps in the docs). Locally: typecheck, lint, prettier and the host-runtime vitest suite pass. (AI-assisted reply.)
