Wayland 1.7.0 Marks an Important Release 189

jones_supa writes: The 1.7.0 release of Wayland is now available for download. The project thanks all who have contributed, and especially the desktop environments and client applications that now converse using Wayland. In an official announcement from Bryce Harrington of Samsung, he says the Wayland protocol may be considered 'done' but that doesn't mean there's not work to be done. A bigger importance is now given to testing, documentation, and bugfixing. As Wayland is maturing, we are also getting closer to the point where the big Linux distros will eventually start integrating it to their operating system.

Wayland 1.7.0 Marks an Important Release

    I keep hearing about Wayland release this, and Wayland release that. That's all great - keep releasing new versions, that's progress. But I want to know, when can I install a GNU/Linux distro and start using Wayland. I know, it's next year, but we'll said that for a couple of years now and I'm running out of patience.

    Second is the protocol
    documentation, which is mechanically generated from the protocol
    definitions and works more like a reference manual. Third is the code
    documentation, which is also mechanically generated but from the library
    source code itself.

    That's the right way to do it. They use pelican, xmlto with some customized XSLT and graphviz for maintainable high-level diagrams.

    Pretty cool. So far I have only used sphinx (and doxygen before), but these days there are a lot of great documentation options out there.

    After it was announced a year or two ago, I have heard nothing about RDP support in Wayland. Is it getting to the point that Wayland will have first-class support for transparently remoting apps with RDP? Anyone know the status on this? There's precious little info about this on the interwebs, and no real information on what the workflow looks like, say with ssh forwarding.

      Remoting should be done at the toolkit level. This is where it belong. Similarly to sftp, gtkclient->ssh->intertubes->ssh->gtkapp

      in practice you would call "gtkclient user@host:/path/to/gtk/application" which would connect the ssh pipes, set envar GTK_BACKEND to "pipe" and run the app. Gtk api get serialized both way, piped through ssh and run locally on your gtkclient which use what ever display backend your desktop is set to. This way you get the absolute minimal network traffics with zero lag

          We've moved from displaying remote applications from the xlib level over ssh, to the toolkit level over ssh (as parent described). It's Unix moving forward, finally.

          Microsoft's proprietary RDP protocol or alternatives such as VNC work differently (and usually pretty slow, since they work similarly to xlib, passing compressed bitmap images over the wire). If you want a remote desktop and your network link is fast enough, that's fine, but for most cases, toolkit-over-ssh is more secure and efficient.

            What you say only applies to VNC. RDP only passes bitmaps when it needs to draw bitmaps. The protocol sends rendering primitives to a thin client, much like X. It can even send fonts or a video/audio stream to let the client do the rendering or decoding.

                      If you own the client and the client logs on to something it would seem to me this is game over you must assume everything the client has access was compromised unless you have reason to believe otherwise... as we already know SSH provides file system access by default to all clients. I'm failing to comprehend the difference.

                      SCP moves one file. SSH doesn't move any. RDP makes every file the target has access to directly accessible as a file share on the client even if you don't want it to.

                      CryptoLocker running on the client wouldn't have seen the files the target could access at all had the connection been VNC, X, or ssh.

                      So this is just a security by obscurity play. The assertion is since a particular instance of malware lacks a feature set enabling it to detect and subvert SSH connections from a compromised client then SSH is more secure than RDP even though both offer functionally equivalent access.

                      Sounds like all the wrong lessons have been learned from this security breach.

                      Also worth noting RDP maps the clients local resources to remote server not the other way around.

        Ahh interesting. Makes sense, but I disagree about that being the right way to do it. The way you describe is hackish, having to run a client. We need the ability to simply remote log into a machine and run the binary and have it work. This is disappointing, if this is indeed the way they've chosen to go. Shouldn't matter what widget set an app uses; it should work (by some definition of the word "work") whether locally, or on a remote machine.

      Biggest issue here: Wayland -itself- has _NO_ support for network/RDP. Its merely a protocol between applications.

      And there is the issue: GNOME/KDE (cant say for Enlightenment) are basically repurposing their X11 stuff. As you know the Xserver was network transparent, so neither GNOME/KDE has any capabilities to piggyback on. So I assume the answer here is "no time soon".

      As for Weston, I have not tested it, but Weston does include RDP support from what I can tell.

        The best seamless remoting implementation for X11 is no longer actually using the X protocol. Xpra does remote X applications using compositing and window management hooks rather than anything involved in the X11 protocol interaction.

        However it's been a bit of a mystery to people if that code actually is in usable state and how it is operated.

        • There was an RDP backend on top of Weston. There's a big difference. Wayland as a protocol does not have any concept of network rendering. They said it themselves on their docs, any remoting abilities need to be written as a separate piece such as a server sitting on top of the compositor, or handled entirely on the client side.

          They demonstrated the former using Weston, but it has nothing to do with the Wayland protocol.

    For those of us who have not heard of Wayland, the following is how the summary reads:

    The x.y.z release of Some Software is now available for download. The project thanks all who have contributed, and especially the desktop environments and client applications that now converse using Some Software. In an official announcement from Some Author of Some Company, he says the Some Software protocol may be considered 'done' but that doesn't mean there's not work to be done. A bigger importance is now given to testing, documentation, and bugfixing. As Some Software is maturing, we are also getting closer to the point where the big Linux distros will eventually start integrating it to their operating system.

    So what does Some Software actually do and why should I be interested? I know that I can Google Some Software, but is it really that hard to start with the summary with the following:

    The x.y.z release of Somesoftware, a package which does blah blah blah, is now available for download. ...

    After all, phrases such as "As Wayland is maturing", imply that this is a relatively new piece of software still under development of which everyone is not familiar, especially for those of us using BSDs, Solaris, and Slackware.
