Project Overview项目介绍

DSH host plugin that injects legacy-browser polyfills into every served page via the webserver tapIndex hook. Core capability: detect and patch missing APIs such as AbortSignal.any and structuredClone at the HTML level, fixing RPC flows like the in-app directory picker. Use when running on old Android WebView kernels (e.g. MuMu's bundled browser) that lack these APIs. Caveat: the mount is gated to Android via the disabled flag, and the polyfills are idempotent.

DSH 主机插件,通过 webserver 的 tapIndex 钩子在每个返回页面中注入旧浏览器 polyfill。核心能力是检测并补齐 AbortSignal.any、structuredClone 等缺失 API。适用于 Android 旧 WebView 或 MuMu 内置浏览器等内核老旧导致目录选择器等 RPC 流程异常的场景。需注意:仅 Android 平台启用(disabled 条件按平台判定),且 polyfill 注入具有幂等性。

Host plugin for DeepSeek Harness that injects legacy-browser polyfills into every served page via the webserver tapIndex hook, and bridges the shell APK's directory picker and path-open channels.

Background

Older kernels (MuMu's bundled browser, older WebViews) lack APIs the host page calls directly:

  • missing AbortSignal.any() breaks the workspace directory picker's concurrent RPC cancellation;
  • missing Promise.withResolvers() breaks the host boot-ready tail script, failing the plugin tree;
  • missing global Iterator (Chrome 122+) makes upstream 0.1.5 client bundles (documentpreview and others) throw Iterator is not defined at import time ("Failed to load plugins").

The plugin injects idempotent polyfills at the HTML level — no browser-side changes needed.

Quick start

1. Install — package into the profile's node_modules.

2. Mount — in the profile's cordis.patch.yml:

- insert:
    - id: web-compat
      name: '@dsh-android/dsh-host-web-compat'
      disabled: !!js process.platform !== 'android'

3. Restart the service; the picker works again in old kernels.
