Overall seems pretty good. The size of the "database" was cut in half
too. Are you using the new callback-based log retrieval now?
What is your plan/roadmap from here? It seems like the overall
presentation could still use some work. I do not find the output (the
graph itself) terribly enlightening in most cases. There is just too
much information. In general, I do not find the TortoiseSVN graph
terribly useful either, but with all of the filters they have to cut
down the information I have seen cases where it can be pretty good.
Does using a custom database format make it more difficult if you want
to store merge information later?
Getting back to the presentation, I have also seen a lot of cases
where there is incorrect information displayed. Usually a revision
is just repeated multiple times. For example, I have a repository
where I did a big import in r1. Then commited some sample changes in
r2 and 3. If I look at a history of a file, I might see r1 listed
several times, then see r2 and r3. I've seen similar duplication when
looking closely at some of the diagrams from the SVN repository.
Anyway, good progress. Looking pretty solid.
