Backend stuff

Winter has hit here and along with insomnia i'm not really feeling like doing much of an evening but i've dabbled a few times and basically ported the Java version of a tree-revision database to C.

At this point i've just got the core done - schema/bindings and most of the client api. I'm pretty sure it's solid but I need to write a lot of testing and validation code to make sure it will be reliable and performant enough, and then write a bunch more to turn it into something interesting.

But i've been at a desk for 10 hours straight and my feet are icy cold so it's not happening tonight.
