Developing with libyui/libzypp & python – part3

October 3rd, 2008 by

In part 1 we installed and tested libyui and its python binding and part 2 was about constructing the GUI. Now its time for the libzypp-bindings – of course for python ;) . So far the GUI looks like:


We will import a repository’s metadata and list its content. But let’s move on …
I assume you have already installed the software from part 1. Then we’ll just donwload the missing parts.

Developing with libyui/libzypp & python – part2

In part 1 we installed and tested libyui and its python binding. Now let’s take a closer look at its usage.

Developing with libyui/libzypp & python – part1

September 14th, 2008 by

In a small series of posts I’ll describe some tips and tricks for developing with libyui and libzypp in python.
Thanks to the YaST developers and Klaus Kaempf, there are bindings to libyui the Yast User Interface library for python.
For libzypp there are also python-bindings done by Duncan Mac-Vicar Prett and Arvin Schnell.
Both are generated with the swig code generator and are not perfect yet, but as we’ll see they’re pretty usable.

One big problem we need to solve is: libyui and libzypp are part of your base-system/YaST. If we would update them in the main system,
we would probably screw up zypper and YaST – which is bad.
Therefore I compiled libyui and libzypp and all other needed packages with an custom –prefix (/opt/yuitest) inside the openSUSE Buildservice.
Thus we can easily install the latest version without breaking our system.

In this first part we’ll install and test libyui.

arm worker on i586 host

September 1st, 2008 by

Last week I joined the obs-cross “task-force” ;) and Martin Mohring posted two nice articles about it ([1] [2]).

Today I played with it and got a i586 worker to build for arm.

Here’s a summary what I did:

  • Installed a cross-obs, as done in Martin’s article
  • Copied init_basesystem and build from /usr/lib/build/ to /usr/obs/server/build (to have the same changes as for ‘osc build’ for the worker)
  • search for “my %cando” in bs_dispatch, bs_repserver and bs_worker and change 2 lines to:


    • 'i586' => ['i586', 'armv4l'],
    'i686' => ['i586', 'i686', 'armv4l'],

  • (note: this is just a hack to get it running – our obs-experts are already working on a smarter solution)
  • update: not needed anymore!: added BUILD_USER=root at line 1201 in file /usr/obs/server/build/build to make dh_testroot happy (HACK!)
  • update: use this! Edit /usr/lib/obs/server/build/build , uncomment line with “-rfakeroot” and comment out next line. Also replace “-rfakeroot” with “-rfakeroot-tcp”
  • run sh /usr/sbin/qemu-binfmt-conf.sh
  • start the worker (on the same machine! – otherwise at least install the mentioned qemu!)

    • Now the worker gets a job assigned and does the same magic arm-build as shown in Martin’s posts.

    An enhancement would be to let the workers advertise their “cando”-archs and assign the jobs according to the info recieved by the workers.

    Hackweek review

    September 1st, 2008 by

    Tnx to Andreas Jaeger I could join the Hackweek crew for the cross-obs on Tuesday and also talk to several others on Wednesday. E.g. me and Beineri visited Andreas Bauer got him to include the link to the Monitor-page on “My Projects” (r4789).
    Atm I’m looking at how kiwi can/could work with cross-obs.

    And for all – Here’s a collage of some of AJ’s pictures from Tuesday:

    GUI with python and libyui

    August 7th, 2008 by

    For some days now I’m working on a GUI written in python. I needed X and konsole, so I gave python-yui (python-binding of libyui) a try.
    Libyui is the YaST2 User Interface library and python-yui is part of openSUSE 11.0.
    If you want to have a quick look you can try my (demo-) widgets.py. It shows some, but not all widgets available. Klaus Kaempf uploaded it to the svn (tnx!).
    Dependency:
    zypper in python-yui
    wget -nd "http://svn.opensuse.org/svn/yast/trunk/libyui-bindings/swig/python/examples/widgets.py"

    a) with GTK/QT GUI:
    python widget.py

    b) with ncurses/konsole GUI:
    export DISPLAY2 = $DISPLAY; unset DISPLAY; python widget.py ; export DISPLAY=$DISPLAY2 ; unset DISPLAY2

    Have Phun!
    Edit:
    Here’s a screenshot,

    Hamradio packages for openSUSE 11.0

    May 13th, 2008 by

    Together with Tim Fischer I’m packaging hamradio-related software in the “hamradio”-repository in openSUSE Build Service. We are now prepairing updates and start of packaging for upcoming openSUSE 11.0 .

    If you are interested in helping us, feel free to contact us! Also if you miss a package in our repo.

    I’ll blog on the progress here …

    Edit: The repository is http://download.opensuse.org/repositories/hamradio/
