Wayland/Weston Gets Forked As Northfield/Norwood

An anonymous reader writes "Weeks after Canonical announced Mir, Wayland's display server protocol and Weston compositor have been forked. A contributor to Wayland found differing views with the project over desktop eye candy and other technical decisions to the X11 successor, which resulted in forming the Northfield and Norwood projects. The developer, Scott Moreau, has been outted from the project but has provided a lengthy explanation why the fork was needed to advance the Linux desktop."

Survival of the Fittest

[jarich]

I'd never do it myself, but I'm looking forward to seeing which projects survive and how they change the landscape in five years. X11 was difficult to use for years... let's see what a little competition can do for innovation and usability.

The good thing about Open Source is that if two contributors strongly disagree on something, both are given an equal opportunity to prove their point. In the end, society wins.

Re:Survival of the Fittest

[Anonymous Coward]

No. Instead of working together to resolve their differences and taking the best technical ideas from both groups to enhance the core product, they have a whiny bitch fest, split the development teams, create two products which end up lesser than the original, create an artificial need for more developers, reduce the advancement of the state of the art, and cause people new to the area to spend twice as long researching which products they should use.

In the end, society loses.

Everybody involved with the wayland project is happy to see weston (the reference display server) get forked to be developed into a more usable desktop environment. That's basically what it's for, and this is far from the first (ubuntu forked it, ADWC was another fork).

This entire article argued he couldn't do what he needs with a plugin alone, which is not relevant to his problem with the wayland community. The problem was his refusal to use the existing mechanism to retain protocol compatibility by copying the existing protocol code into a new extension and modifying in there: http://lists.freedesktop.org/archives/wayland-devel/2013-March/008172.html

In four pages, he didn't address why he didn't feel like doing that.

Re:More information

[slack_justyb]

Because that solution just sounds silly.

The whole point of Wayland, and I could be wrong on this one, is to avoid the mistakes of X. From your solution, we just go back to the days of hack around the core.

The core protocol is flawed and the project shouldn't be afraid to make some sort of shift when there is a pretty good reason for that change. If dude was purposing change for just change sake, yeah I would get it. But the protocol doesn't implement basic window management within the core, and makes it insanely difficult at the plugin level. I, for one, think dude has a point.

That is exactly what happened to X. Everyone was afraid of changing the core protocol, afraid that it would break older stuff. Look where that got it. About a bazillion extensions. At some point backwards compatibility breaks the baker and I know that is hearsay in the OSS community. I know there has been a lot of boneheaded change for change sake forks, but I really don't see this as falling into that category.

The core protocol is flawed

Bullshit!

The core protocol is very very good.

There are a fewnow obsoloete bits like the bitmap graphics and fonts, but the rest of the core is fundementally sound.

So, unless you can provide some evidence that the protocol is flawed, then go back under your rock.

Oh yeah and Keith Packard: quotes don't count. He might be a core X11 developer but he's also a one man FUD machine, which is really sad.

About a bazillion extensions.

So? Let me repeat that, so?

The protocol is *designed* for extensions. Extensions are simply the X equivalent of adding more API calls.

Look at Linux: it is a POSIX kernel, but with LOADS of extensions! Does anyone whine "oe woe posix is flawed linux has so many extensions it's fundementally broken lets nuke it stard from scratch and by the way no one needs multi user right?"?

Seriously, who the fuck cares if they're "extensions" or "core", any more that if I care if the networking zero copy super low latency fast stuff is an extension or in the core POSIX system call interface? A clue: no one cares.

No one cares on Windows either! Turns out that Windows 8 implements all those Win32 calls right back to the Win32S (a Windows 3.X era thing) API. Do you hear anyone complaining that because Windows has some old API calls in it that it is fundementally flawed and the mere existence of old APIs taints it? No, because that would be stupid.

Likewise: you know OSX used to allow you to run OS9 and earlier binaries! My got it supports old stuff!! It must be fundementally flawed! Oh my god! Every system supports some degree of backwards compatibility!! They are ALL FLAWED! We must rewrite them all in javascript on the cloud in HTML5 except that all the browsers can render HTML 3.1 so they are flawed too!!!

Here's what astonishes me: people hate X so much that they complain (a) when it's too old and (b) when the developers add API calls to make it more up to date!

Actually, I'm in favour of updating the core protocol, or adding some hefty extensions to reduce latency NX style---though XCB actually is a fair improvement over xlib---but Wayhand is not the answer to that because it removes basically everything.

"Advance the Linux desktop..."

[Torodung]

"Advance." You keep saying that. I do not think it means what you think it means.

What is needed, before "advancing" anything, is to advance acceptance of the Linux desktop, and IMHO this ain't helping.

I'd rather take one solid piece of software than 10 which are broken in different ways.

Re:When are they going to use motion sensing and 3

[Anonymous Coward]

It's about time the entire desktop go 3d. It's 2013 and video cards can do it easily. Instead of windows why not just use rotating cubes?

You can easily do that without some fancy display driver or even 3d glasses. Just strap together 6 monitors into a cube shape and fashion a suitable base that will let it rotate in 3 axes (probably best to put the CPU inside the cube so you only need to provide power to the cube). Then to change desktops just flip the cube in the appropriate direction.

While the emerging display servers fight it out...

[Bill_the_Engineer]

While the emerging display servers fight it out, I think I'll just stick to the tried and true X11.

Re:Just what we need...

[lgw]

If an ordinary application can't be written once to look fine on both, then really it is a new flavor. If the application writer doesn't have to know or care, then it's not.

This fork happened over the difficulty in adding candy to the UI, so in theory all the apps that aren't the shell shouldn't care, but in practice, well, time will tell.

Explanation

[Alex Belits]

Once Wayland components developers started trying to implement something practical, they discover, one by one, that they need those "unnecessary" X features after all, however there is no way to explain it to the rest of developers, who still believe that removing everything they don't immediately use in their narrow area is a great design practice.

Next Woburn/Billerica

[us7892]

I hear that Woburn/Billerica is the next fork of Wayland/Weston, while Wellesley/Southboro is the next fork of Northfield/Norwood. Coming on the heals of Woburn/Billerica is the Provincetown/Gloucester fork. And they're really planning a breakout with a Providence/Cranston fork....

You have only worked on trivial problems

[Tenebrousedge]

There comes a point where there is no readily identifiable "best" strategy. Perhaps there are tradeoffs in either direction. Perhaps one persons says, "the rule of thumb that holds for the common case, doesn't apply here." Perhaps there are valid differences about what goal to optimize for -- it is a law of the universe that you can't optimize in all directions at once.

At some point the only way to decide the issue one way is to fork the code and see what becomes popular. As an outsider, you don't really have a good perspective on whether this is justifiable. Clearly the magic code factory has stopped for the moment, but coding efforts are probably stalled more often than not. I started on a new project a few weeks ago, and I don't expect to be doing anything but refactoring and bug fixes for several weeks to come. And if I decided that it was just as much trouble to start over with a bare set of classes and do things the way I think they should have been done the first time, are you going to call me out on it? Is there any better proof of the viability of that strategy but in the execution? Perhaps this will be a better performing or more feature-ful product, and perhaps not, but if the only thing learned from the experience is that "doing it this way turned out to be a bad idea," that still counts as a win in my book.

A failure is something you don't learn anything from.

Lastly, as counterproductive as a fork may be, it's nowhere near as hard to merge changes as it would be if the guy had just started a whole new project. Which is the biggest reason to cry foul over Canonical's development efforts.

Re:Just what we need...

[hawkinspeter]

If he's right, then maybe his fork will gain momentum. If he's wrong, then he'll be wasting some of his time, but I bet he'll learn from the experience either way.

Often it takes someone to branch out and start something to jumpstart development so that other people see what's been done and think it's worth contributing to. Unless someone makes that jump, we'd never know what might have been.

Re:The primary commit history for the past year...

[MBGMorden]

I think the desktop on Linux is truly approaching it's demise.

Actually I think the desktop's only future is on Linux.

Most of the regular users are moving on to tablets and phones. Even in businesses I'm starting to see people migrate to just a tablet. There's still plenty of desktop users but at the rate we're going desktop computers will be a thing of the past within the decade.

I'd wager that geeks and Linux types will be the only ones who still want a desktop OS and system by 2020. We'll probably be running on off the wall hobbyist hardware (Raspberry Pi type devices) and hooking up to mostly HD televisions as monitors if purpose built monitors aren't still available.

I'm not complaining - I'll be keeping mine too as even as a technophile I still prefer to sit down to a full system rather than use a tablet, but I truly think that there will eventually be a "year of Linux on the desktop" - it'll just be after most of the world has forgotten about the desktop.
