X Census (for 1.9)

Topic’s name is a funny (and friendly) devotion to GNOME Census. So let’s take a look at some numbers from the time Xorg 1.9 was in development – raw data is here.

Would be unfair to measure only the work that happened e.g. in X server or in the drivers being developed and come up with the statistics about “who developed X”. X and X development community are quite extensive and don’t concern only “graphics” related, i.e., pixel information that appears on your display screen. This is a very common mistake.


X does input device event processing, device keys mapping (e.g. keyboard), pixel rasterization, output and input devices hotplug and configuration, devices and user session pairing, (different) 2D/3D graphics implementation, frame-buffer content management, X application and session security, application memory resources testing, analysis and debugging and etc. So it’s far from just pixel showing up on screen.

X is a generic graphical system. I prefer to see X as an implementation that doesn’t handle (or should not) system-level resources like memory or frame-buffer content. Other people see a bit differently. Given so, I divided all X development in the following groups, that you’ll see below as bold. Statistics were generated from the time people were working on 1.9 Xorg (02 Apr to 20 Aug):

The proto set of repositories represents the X11 core protocol description together with its extensions. The implementation of X11 and extensions to be used by clients are inside lib and xcb. lib also contains some few libraries to be used within xserver. xserver contains the server implementation of X. So here are the numbers for X implementation (xserver, proto, lib and xcb repositories):

X drivers, although decreasing in functionality with the time, they still touching kernel and system-level tasks. And that’s why I prefer see those separated from the rest of X implementation.

Nothing or close to nothing was done in the old font scheme (font repo), bitmap and cursor data. Also, from the total of 85 X traditional applications (apps), only 180 changesets were made and mostly concerning autoconf clean up.

Of course lines of code and changeset are far from being a good metric to see actually how the development happened. But still, it does represents something. For sure, there’s also a lot of other inaccurate information that I’m missing from this all. For instance, companies like Collabora does X development but sometimes get the merits for Nokia. Is that fair? I don’t know. And I don’t want to discuss this either :)

PS: Canonical, where are you here? Hint hint hint.

    This is really nice, Tiago. It’s cool to see who’s doing all the work.

    One complaint I have is the XTS numbers. I’m not sure when you’re measuring from, but I certainly had more than 9 commits. I hammered on that piece of crap for months.

    http://cgit.freedesktop.org/xorg/test/xts/log/

    I guess I see that you’re measuring during the server merge window. While that’s arguably for the server, for everything else it’s probably more accurate to measure from katamari to katamari. For instance, for someone working on xrandr, the server merge window is an arbitrary slice of time.

    Maybe next time. Very cool regardless.

    the command I used was basically this one:

    $ for i in `ls`; do cd $i; git log -M -p –after=”2010-04-01″ –before=”2010-08-20″; cd -; done | /home/tiago/git/gitdm/gitdm -l 10 -c ~/git/gitdm/sample-config/xorg/gitdm.config-xserver -b ~/git/gitdm/

    so, the period was the patches were _commit_ after=”2010-04-01″ and before=”2010-08-20″. Are you sure it’s not 9 only?

    Anyway, thanks for the words Dan!

    Did you consider including commits to the relevant kernel modules too? I know RH’s ‘X.org’ hackers spend quite a lot of their time working on the nouveau, radeon and intel kernel modules these days.

      Maybe I should include drm and kernel graphics related stuff (from Linux? I dunno). But again, it’s just tough to define the line of “what’s X” and I preferred to do on such way.

        Thanks for running these stats. Agree with Adam that DRI infrastructure is certainly worth covering.

    Come on, you’re complaining about Canonical while you omit that they had the same amount of changesets during 1.9 cycle as Novell, Mandriva, or even Google. If you want to be fair, compare them the fair way.

    A sign of evil!!!

    I feel this is a fair comparison,the changesets do not really matter,these statistics are fairly accurate,thanks for the Info.

  7. X Census (for 1.10) « Tiago Vignatti Says:

    [...] of 1.10 window for all X infrastructure – raw numbers here. I did it in a similar way as the previous version. Worth to mention that there’s almost no relation between the cycles of development from each [...]
