dsh-setting-restart

One-click restart of the DSH service, from Settings → General. The "一键重启" row is pinned at the very bottom of the General settings page — no matter how many rows are added above it later, it always stays the last one. After the restart the page reconnects automatically and the row confirms it with a green "Connected" state, so you always know the service is back.

Features

• A one-click restart row at the bottom of Settings → General (below "繁忙时 Enter 键行为" / whatever comes last).
• The row is pinned with the maximum slot order, so it always renders at the bottom of the page.
• Restart is a real process restart: the host spawns a detached helper, exits, and the helper re-spawns the exact same dsh command (same executable, arguments, cwd and environment). The browser tab reconnects automatically once the new instance binds the same port.
• Bilingual UI copy (简体中文 / English), following the DSH client conventions.
• Fully typed host invocation through the DSH Typert RPC registry (settingRestart/restart).

Requirements

• DeepSeek Harness dsh ≥ 0.1.0-rc.6 (the web profile).
• Node.js ≥ 20.

Installation

1. Install the package into the web profile (this runs pnpm add inside the profile directory):

   dsh plugin --profile web add dsh-setting-restart

2. Mount it as a loader entry by appending an insert patch to the profile's user patch layer — $DSH_HOME/profiles/web/cordis.patch.yml ($DSH_HOME defaults to ~/.dsh):

   # $DSH_HOME/profiles/web/cordis.patch.yml
   - insert:
       - id: setting-restart
         name: dsh-setting-restart

3. Start (or restart) the service:

   dsh web

4. Open Settings → General — the "一键重启" row is at the very bottom. Click 重启 to restart the service; the page reconnects automatically.

The same patch can be added to the home-level $DSH_HOME/cordis.patch.yml to enable the plugin for every profile.

Configuration

The loader entry accepts an optional config block:

- insert:
    - id: setting-restart
      name: dsh-setting-restart
      config:
        exitDelayMs: 1500    # delay between the click response and process exit (default 1200)
        waitForExitMs: 30000 # how long the helper waits for the old process to exit (default 30000)
        respawn: true        # set false when a supervisor (systemd/pm2) already restarts the service

How it works

browser row (client.js)
  └─ connection.rpc.call("/api", "settingRestart/restart", { args: {} })
       └─ api-gateway dispatches the strict typert invocation
            └─ SettingRestartService.restart() (index.js)
                 ├─ spawns relaunch.js detached  ── waits for pid to die ── re-spawns the same command
                 └─ process.exit(0) after exitDelayMs

• client.js — the browser bundle (dsh.client / exports["./client"]) that registers the settings row.
• typert.host.js — the TYPERT host manifest (exports["./typert"]) declaring the strict settingRestart/restart invocation.
• index.js — the host plugin (SettingRestartService) that performs the restart.
• relaunch.js — the detached helper that re-spawns the command after the old process exits.
