Yep, I would guess those are all some of LL's reasons for switching away from SVN. Also, speaking from my experience using SVN for several years before switching to Git (which is close enough to Hg), using a distributed version control system just changes the way you work, and the way you think about version control and software development. Personally, I think that mental shift is even more important than the new features and tools and easy merges (which are also very nice, of course). Think of the old lock-based systems, where one team member would "check out" a file, and no one else could edit it until they were done. Once people switched to systems like CVS or SVN that let all the developers keep working without blocking each other (as much), it really altered and improved how software was developed and how teams worked together. Distributed systems take this to the next step, and again it alters and improves the way developers work and collaborate. Plus everything's just way faster. :-D I never realized how much time I spent waiting for a SVN commit to finish -- or even checking the log -- until I used Git. Now I'm completely spoiled, and waiting 10 seconds to contact the server just to look at the log, or 30 seconds (or even minutes (!) for big changes) to commit feels like an eternity to me. It may seem like a little thing, but it feels so much nicer when nearly every operation is near-instantaneous. - Jacek _______________________________________________ Policies and (un)subscribe information available here: http://wiki.secondlife.com/wiki/OpenSource-Dev Please read the policies before posting to keep unmoderated posting privileges
