Buzztard & Distro Versions

I started hacking on the transport settings. The idea here is to have a generic scheme for how to control playback (start, stop, seek) externally. This can be a midi-controller, but also qjackcontrol or a MPRIS applet. The setting now show the available modules and allow to enable master and slave mode as well as mode specific settings. I could remove the combobox from the toolbar again.

As a next big thing I started to refactor a big chunk of duplicated code in core. Machines have global parameters, per voice parameters and per incoming wire parameters. Now we have a parameter-group class that deals with those.

I spend the rest of the month cleaning up the test suite and the autofoo setup. On the latter I bumped the required versions. The policy now is to support the linux distributions from about the last two years. This allowed me to remove large chunks of conditional code. Unfortunately it is not easy to do that. The easy part is to check what versions we require, by looking at the pkg-config macros in configure.ac. Then we can also grep for conditional section in the code:
find . \( -name "*.c" -o -name "*.h" \) -exec egrep -o "[A-Z]*_CHECK_VERSION\(.*\)" {} \; | sort | uniq
Now the tricky part is to figure what distributions ship. It is somewhat easier for debian/ubuntu as they have pages like:
http://packages.debian.org/search?suite=all&arch=any&searchon=names&keywords=libgstreamer0.10-0 http://packages.ubuntu.com/search?suite=all&section=all&arch=any&searchon=names&keywords=libgstreamer0.10
For fedora Company suggested to look at the spec files in git and iterate over the branch names
http://pkgs.fedoraproject.org/gitweb/?p=gstreamer.git;a=blob;f=gstreamer.spec;hb=f17
For opensuse Vuntz suggested to use an osc query at which I failed misserably and in the end checked the packages in the repo and iterated over the versions:
http://download.opensuse.org/distribution/12.1/repo/oss/suse/i586/
Anyone know better tricks? Please share them!

One more motivation for doing this is upcomming gsoc. If I am lucky to get a student who will port buzztard to gstreamer 1.0. We'll release a 0.7 of buzztard before we switch to the new gstreamer api.
