GNOME 3 wasn't designed to be parallel installable. Right?

continuing to repeat a meme won't make it become truth, you do realize that?

GNOME's platform is, and has always been, parallel installable - that's an acquired skill, and we've been saying how to do it properly for the past 10 years.

applications are not parallel installable (or, at least, they are not by default): there is no totem3 to be used alongside totem2, or nautilus3 to be used alongside nautilus2. that's perfectly fine, and it's up to the individual maintainers to decide that. you cannot run gnome-panel2 alongside with gnome-panel3 either, because (believe it or not) gnome-panel is an application; the applet library is parallel installable, though.

I sincerely hope that people stop repeating crap propaganda spewed by people with far less than the required amount of clue and an axe to grind.

By your description it seems that there are processes and not just libraries that GNOME2 applications can depend on, such as gnome-panel, that aren't parallel installable with GNOME3. I'm not familiar with the internals of GNOME but what about notifications or IPC or VFS plugins?

It seems that it would be good to make the same sort of platform API guarantees that the Linux kernel makes to userspace or that glibc makes so that third parties can expect their application binaries to continue to function for decades and that the system won't be deprecated out from underneath them.

Anyway the main point of the article is supporting a GNOME 2 style theming using extensions to GNOME Shell which seems like a good idea for users who prefer the old style workflow. Even Windows maintained a classic interface option when introducing changes XP and 8 and was more successful for doing so. This is a positive thing.

There are some APIs that many wind 95/98 apps depended on that are broken in recent versions of windows.

Anything WordPerfect relies on? My version - certified for W2K iirc, doesn't work very well on XP. And my old version, that runs fine on Win9x, is totally broken on XP :-( I don't think I can even install that newer version on 7.

A lot of my wife's programs - sold as "runs on everything Windows" in the Vista days, is now broken on 7. And because we've got the Home version, running it in XP-compat mode isn't an option :-(

I'm not familiar with the internals of GNOME but what about notifications or IPC or VFS plugins?

IPC and VFS, and settings, are sitting at the GLib level, our lowest common denominator; GLib's API and ABI were not bumped.

a lot of functionality that was in separate libraries was deprecated and moved into GTK+ 3.x and GLib; the symbols are different, and the libraries are still available for applications to use, so you can definitely run a GNOME 2 application in GNOME 3, should you choose to do so. obviously, it would be better to port to non deprecated tech, but it's not mandatory.

let me give you a for instance: Banshee is a GTK+ 2.x (and GNOME 2.x) applications, given that only recently Mono has been updated to support GNOME 3 API; I can use it without an hitch under GNOME 3.4 and 3.6, and all its functionality remains untouched. true, some stuff works better when integrated in GNOME 2's panel - but to be fair, it's all inside extensions that can be removed, and I look forward to the point where Banshee will be a proper GNOME application again.

the core applications in GNOME are tied pretty much with the rest of the environment, because they are designed to be that way; you can avoid using Nautilus, after all, but you cannot complain that Nautilus 3.6 does not work without the rest of its dependencies, because Nautilus is not meant to be a file manager that can work under every desktop environment under the sun - and it certainly isn't up to you to tell the Nautilus maintainers what they have to spend time on.

the whole point of the "GNOME Classic" exercise is to provide a different workflow for some users without shipping a completely separate set of dependencies (which we cannot maintain, and that nobody stepped up to maintain in the past 3 years, even after repeated calls for it).

Please be less vague, less accusing and less pointless sarcasm. That or don't complain when you get a response in kind.

As said elsewhere: XMMS still will run fine under GNOME 3. And I do mean the gtk+1.x compiled XMMS, though maybe your distribution doesn't ship it anymore.

Someone complained about parallel installs of GNOME2 and 3.

ebassi says that the gnome 2 libs are parallel installable so it's all good.

But then later admits that doesn't actually help that much since application functionality is often reduced/broken in GNOME3. HIS example was Banshee. But it's all the user/applications fault, not GNOME3.

I questioned the benefits of the changes that caused that breakage.

Your defense was that OMG! XMMS still works.

A true WTF. I'm not even sure why you would make the leap to XMMS.

XMMS has nothing to do with this conversation.

The work done at the library level doesn't always help the end-user though. E.g. "Referencer" is a really nice GTK+ C++ BibTex management app. It used some APIs that moved from a GNOME library (gnomevfsmm? gnomeuimm? I forget which) to Glib (to do with URIs and VFS). Unfortunately, Fedora decided these were crufty old, deprecated libraries and stopped shipping them - and so stopped shipping referencer too.

I tried building the old srpms, but that leads to a huge number of dependencies, including old gnome stuff that conflicts - iirc. So that wasn't practical, is my vague memory.

I got maybe a quarter to a third of the way of converting Referencer over to the GLib equivalents before giving up, and deciding it was easier just to switch to using Zotero - which is a cross-platform web service + Mozilla XUL based app.

GNOME Shell to support a "classic" mode

Posted Nov 22, 2012 19:37 UTC (Thu) by jspaleta (subscriber, #50639) [Link]

Great example. Referencer is the _only_ application so far that I've been beaten up about in my family technical support role in the transition from a gnome2 to gnome3 desktop experience on Fedora.

When it went missing I given a very specifically told to get that back on the desktop and laptop systems in use. So I resurrected the necessary bits from Fedora packaging git and rebuilt it and its "longer than I really felt comfortable with" set of dependencies for in-family packages. I'm sure as hell not going to offer to maintain this for anyone outside my household.

We are evaluating replacement applications. So far, the user in question hasn't really liked the other options available. If it were a C application, I could probably seriously take a look at porting it. But the fact that it uses c++ bindings, bindings which themselves are not being ported afaik, porting it is a not starter. I'm not going to put myself on the hook for maintaining low level c++ binding as prereq to port this application. It'd be easier to nuke it from orbit and rebuild it as C or vala using the maintained bindings.

WTF? There are no C++ bindings for GTK3?

GNOME Shell to support a "classic" mode

Posted Nov 22, 2012 21:05 UTC (Thu) by paulj (subscriber, #341) [Link]

There are. The problem isn't the C++ bindings, it's that some GNOME library got deprecated. Similar, but different functionality, went into a GTK+ library (VFS kind of stuff). The deprecated old GNOME library became difficult to package because of dependencies it seems.

The porting is fairly trivial, but it's not mechanical. Referencer unfortunately uses things like the old URI thingy all over the place. By the 2nd day I got fed up and switched to Zotero.

Given your own description of the existing parallel installation capabilities your tone doesn't seem warranted. Depending on what you want out of such a feature defining core applications as part of "GNOME 3" doesn't seem to be a complete reach.
I realize that it is frustrating to see something you put loads of work dragged through the mud, but accepting that level doesn't help. It also doesn't mean that everybody criticizing is one of the mud throwers.

Ad hominem.

Seriously, GNOME3 dropped a lot of functionality (some of which it still hasn't gotten back) which is is understandable for .0 release.

Why deny that and call me sad?

What is so hard to understand about users wanting to continue to use GNOME2 until GNOME3 becomes viable?

Sure, I replied in kind to the Company post. So that makes me sad?

I agree it was an ad hominem, I was nitpicking on being called a name.

In any case, you complain about "ad hominem", while continuously showing the similar behaviour (just directed at many people instead of 1). And not just this article. It seems similar to the "graffiti theory" (http://en.wikipedia.org/wiki/Broken_windows_theory#New_Yo...). If everyone responds nicely and rejects unnice behaviour, it'll likely be a nicer behaviour overall. To be clear: this is not directed at you. In this article alone you'll note that various people respond harshly towards each other. I noticed that corbet mentioned a while ago that he doesn't want moderation except in extreme cases. IMO this badly affects the comment quality.

You'll see that once the sarcasm stops, the chance of being heard vastly improves.

And criticism is very helpful. If everyone says yes, you only need 1 person.

But hey, criticism accepted, I will tone it down.

Sarcasm is a difficult thing to master well without coming off as hostile.

You are coming off as hostile and perhaps a weebit passive aggressive.

Speaking from my own personal battle with the disorder...
If you are prone to sarcasm, and you don't have the necessarily health care to cover the cost of the meds to control it you can still make a series of choices on when and where you use sarcasm. Control the disorder don't let the disorder control you.

Among many strategies I have tried over the years, the one I find most successful in written communication forums is to keep bulk of the sarcastic comments aimed directly at oneself. I believe the term is self-deprecation. You still might not master right off the bat, unless your British, I'm not so I'm still working on it, but it does help take the edge off a bit when others are reading what I write. Instead of coming off as hostile, when making sarcastic jibes at other people, you just come off as a bit odd, muttering about yourself. And maybe this strategy isn't for you. Maybe you need electroshock therapy. I can't tell you want will work for you. Experiment... maybe try that electroshock stuff a couple of times just to be sure its not the right treatment for you.

It really depends on the tone. There is a lot of feedback given in various ways. If someone people are very aggressive, it tends not to give a good impression.

I am on various mailing lists, mostly just to look for feedback and spot problems. Sometimes one person saying things is enough, sometimes only when many people say something.

Elsewhere the "faster horse" thing was mentioned. If someone gives feedback it can be various things:
- outright bugs
- hardware issues
- something that doesn't work right at the moment
- packaging problem
- performance (known or unknown)
- design/usability problems
etc

All of that is useful to know, but there is not a one on one relation between this. E.g. a "don't drop fallback mode" criticism might be the result of something else, e.g. a hardware issue. Further, if someone doesn't like a nautilus 3.5.92 or even 3.6.0, it could be either a design issue, maybe not. Often what is expected that some suggestion must be implemented immediately. Not always possible... takes quite a bit of time to figure what the feedback really means. E.g. some stuff in gnome-shell 3.0.0 wasn't working nicely, but actually can be difficult to understand if feedback is in the form of "what are you doing?", "idiots", etc.

That's just interpreting feedback, after that knowing what to do, etc.

Not saying things couldn't/shouldn't be improved, just that the expectations are a bit high.

Note that recently I saw a few designers commenting on usability testing, saying that big usability tests (like Sun did) would be very welcome and is a bit lacking atm.

So which distro has GNOME2 (not MATE) and GNOME3?

that's an issue you will have to raise with distribution people - I am not one.

the libraries are parallel installable; we took great care at bumping everything during the 2 -> 3 cycle. if something got lost in the process, it was a mistake, and I'll gladly take the blame by proxy - as well as accept patches.

as I said above, applications do not have parallel installability - but that's something absolutely normal, unless you statically link everything. by the by, we're trying to solve the issue of installing applications in parallel, along with sandboxing and keeping ABI stability in the face of OS updates; it's a large swamp to drain, and something that takes time to implement, and usually gets lots of grief from people droning about the right to choose and the Linux distribution process.

Rubbish. You answered the question.

The "apps" (I would argue that nautilus and gnome-panel are not apps but are the desktop) are not parallel installable.

Which was a deliberate choice by you GNOME devs to force the transition to GNOME3. Which is why people are hating on you.

No one cares if the libs are - I want a the login manager to give me the choice of logging into GNOME2 or GNOME3.

I want to use your code! I just want the choice on which version. I don't want the latest buggy incomplete version. I want to chose when I make the transition.

But I know you guys can't understand how people don't think GNOME3 with no taskbar and no font size changing and no minimize button and 3d hw requirements and no themes and gaudy touch friendly widgets isn't the best thing since sliced bread that everyone should immediately want to switch to.

you configure jhbuild to install into a directory tree that is non standard. In the examples in the docs that is /opt/gnome/
jhbuild when used to run gnome-session sets up shell environment variables so gnome components use the files installed via the jhbuild process.

If you want to look at specific environment changes you run:
jhbuild shell
and you can examine the environment variables accordingly.

Be warned that if you go the jhbuild route, it'll suck up loads of time before you actually get anything working. The "GNOME OS" bit is not to replace a distro, but to ensure that "GNOME" behaves like an OS.

Or in other words: ensure that you can easily join development. Be able to provide people with the latest GNOME release as a VM, including all the various system dependencies which are needed by GNOME. Be able to fully test the whole "OS" (meaning GNOME but also the system dependencies).

To answer your question:
The way that jhbuild does this is by installing everything in different prefix. So instead of /usr, you can have the entire GNOME stack (+ some dependencies) in e.g. $HOME/gnome. You can then tell GDM to launch $HOME/gnome/bin/startgnome.

What I forgot is that this will still share the "dot" files. We've put a lot of work into supporting the XDG directories (~/.config), which can be changed using environment variables. Quite envious of KDE here (they solved that years ago).

Ok. I've used a tool similar to this in the past when I needed newer GNOME libs so I could build the latest Anjuta on RHEL 4.5. Forget the name of the tool at the moment. I believe it is no longer maintained.

So what is keeping everyone who desires to, from running GNOME 2.x & 3.x side by side?
