Specifically, I was referring to the accounting system. Tavin said he had it written down somewhere, most probably the proverbial napkin. Going through the fs.acct code I did find some things that seemed wrong, but I got no responses in my attempts to raise Tavin to comment. I would have to look closer to be sure though. Another interesting issue is with the trees. Earlier there were a lot of complaints about routing table weirdness, ie it would return Route Not Found with only one attempted route even though the table was full. I changed routing table from being backed by a red-black binary tree to a skiplist a while ago. Are these errors still occuring? It would be nice they aren't, because the only other place the red-black tree is used is exactly in the filesystem accounting code, and that could also be made to use skiplists (balancing trees are very complicated structures, and while the one we have passes some VERY rigorous unit tests, some extremely esoteric error condition is still possible. Skiplists by contrast are very simple structures and I'm quite convinced that the one I wrote is working.) Of course, life is never that simple. In the long run though, it is not realistic for us to use a large chunk of code like that unless somebody is willing to maintain it. I don't think there is any reason to believe that Tavin will be coming back for any active work on this project, and while he did say he might want to break out the FS code as a seperate free software project, he does not seem to have much time anymore and for some time now he has disappeared completely. Of course, it should be noted that pretty much ALL the code in Fred is orphanded at this point. Tavin is gone, I think his motivation killed off by concerns over certain aspects of the project, and I am not going to be able to make any significant contributions in the foreseeable future (partially for the same reasons, but also because I'm starting my sixth year at university and somebody told me I have graduate soon :-)). Gianni, to the extent that he had time to learn the codebase in the time he did work on it, does not seem to have much time anymore. Matthew is doing good work, but he cannot be expected to pick up and maintain 70,000 lines of code over night... -- Oskar Sandberg oskar at freenetproject.org _______________________________________________ devl mailing list devl at freenetproject.org http://hawk.freenetproject.org/cgi-bin/mailman/listinfo/devl
