Version 3 - Phase 1

[m1k1o]

This is an implementation of Phase 1 of #371.

In the first phase only server is rewritten and legacy driver is added to ensure combatibility with the old API and config. Client will be only minimally changed to satisfy compatibility with the new workflow.

Currently not supported features

These features will be either deprecated or additional effort must be made to include them in the v3:

• no BAN function - since v3 uses varius member providers, access control is part of them, not neko main codebase anymore - only available for users connected through legacy API.
• no session ID for mute & unmute (shown as Somebody in GUI).
• no session ID for locks when reloading page (shown as Somebody in GUI).
• not sending DISCONNECT before KICK - webrtc destroy was delayed by 1sec.
• last (admin|user) left at won't work for any provider that removed users after logout - implemented stats.
• filetransfer enabled is sent after init and old implementation excepts it in the init - got the information directly from config..
• 32bit ARM is not supported:

API changes in legacy driver

These changes need to be modified on the client side because not even the legacy driver is able to emulate them. Those are mostly some unexpeced order/timing of when the data are sent.

• display name is updated on signal provide what is after the initial members list is sent (shown as Somebody in GUI).

TODOs:

• Migrate demodesk/neko-client to vue3 Vue3 rewrite demodesk/neko-client#47.
• Implement missing features from m1k1o/neko to demodesk/neko and demodesk/neko-client (vue3 branch).
  • global locks - login, control ...
    • control lock already present.
    • login lock implemented in (demodesk/neko@a61eade, demodesk/neko-client@fb0af48).
  • events channel - log all user's actions (who did what and when) and display in event log. (server, client)
  • control protection - to prevent unauthorized control, implemented in (demodesk/neko@0f45aa3, demodesk/neko-client@7eb40ab)
  • Kick and Ban functions
    • added session disconnect that can function as a kick - it disconnects the session but user stays logged in and can login again. probably remote session logout by admin could be added in the future. (demodesk/neko@0e8108e, demodesk/neko-client@06955aa)
    • since we have multiple auth providers, they should take care of this. for now if we disable login for certain user in user profile they are effectively banned.
  • control requesting function - to let the host know someone wants to control (demodesk/neko@59b2fae, demodesk/neko-client@86095ec).
  • implementation as a plugin:
    • filetransfer - upload and download files. (demodesk/neko@a178bed, demodesk/neko-client@b302c98)
      • filetransfer lock implemented in (demodesk/neko@3ee6078, demodesk/neko-client@bc26fde).
    • chat - with can_send and can_receive flags (demodesk/neko@da45f62, demodesk/neko-client@2918e31)
• Extend demodesk/neko to be fully backwards compatible with m1k1o/neko.
  • compatibility with legacy API:
    • ?pwd= - authentication.
      • accepts ?usr= as well, it creates new session each time. if no usr it tries with arbitrary username.
    • /ws - use original WebSocket messages?
    • /stats - use original JSON struct?

      {
          connections: 0,
          host: "",
          members: [{ session_id, displayname, admin, muted }],
          banned: { ip: session_id }
          locked: { resource: session_id },
          server_started_at: "",
          last_admin_left_at: "",
          last_user_left_at: "",
          control_protection: false,
          implicit_control: false,
      }
      

    • /screenshot.jpg - alias / redirect to /api/room/screen/shot.jpg?
    • /file - alias to /api/filetransfer?
    • /health - alias to /api/health?
    • ability to turn off/on legacy API using config.
  • compatibility with legacy configuration:
    • all legacy configuration options should be available
    • legacy pipeline builder video_bitrate, max_fps, audio_bitrate.
  • libclipboard is handled differently; should be an option to switch at build time. there is no UX impact.
  • upgrade docs
    • explain limitations of the legacy driver if its being used
    • list new config options
    • provide migration guide from old to new config options
    • list the new API
    • provide migration guide from old to new api
