Linux QoS API update

My Linux QoS library is coming along nicely. It took me a few days but I changed the whole API to be based on GObject. The main reason for this time consuming change is to make bindings to other languages easier. Primarly I am interested in Mono and Python bindings. As much as I love good old C I have no intention of building a GUI application with C if I don’t have to.

I am now buiding small apps that use the API and discovering the features that are needed but I didn’t think of before.

Everyone who develops software using free software libraries should take moment to thank the developers for thier time and hard work. Developing a sane API is hard.

Linux QoS API

My wrapper library for the Linux QoS system is coming along nicely. Here are the function calls necessary to add a filter that matches the destination field in the IP header.

filt = classifier_u32_new();
classifier_u32_set_class(filt, class);
classifier_u32_set_priority(filt, 5);
classifier_u32_set_protocol(filt, IP);
classifier_u32_set_interface(filt, 3);
classifier_u32_add_match_ip_dst(filt, "x.x.x.x");
if (!qos_classifier_u32_add(con, filt)) {
	g_print("Adding filter failed.n");

I am now trying to figure out how to handle the representation of the currently installed filters and classes in the API. Somehow the application needs a represenation of these things so it can make changes. Since the structure of the qeueing disciplines, classes and filters is very much like a tree I think this may be the best way to go.

Fedora Core 2

I have had Fedora Core 2 installed on my three computers for a couple of weeks now. Traditionally I have used a stock install for my gateway and laptop but have customized the desktop components of my main work station. Typically this meant building the latest GNOME from source via Garnome. Fedora Core 2 is the first Linux installation I have had in a long while that I don’t have the urge to customize. Sure, I have installed some new stuff that is not part of the distribution but the core desktop components are stock. Kudos to Fedora for putting together such a good distribution. Someday I’ll take the time to get familiar with Debian but at the moment I don’t have much incentive to.
