I would like to add a +1 on this topic.

There are very few "official" resources or de-facto recipes on how to set up a git-svn bridge.

According to the 2010 survey [1], roughly 20% use git-svn in some way. A subset of these are probably very interested in a git-svn-bridge setup that works.

I've experimented with my own "hybrid bridge" setup [2], but I've yet to hear whether it's wrong or can be done better. Someone on #git claimed it was more complicated that it had to be, but as far as I've heard, the setup in Loeliger's book is even worse [3] (no offense to his book though, I haven't read it but heard it's great).

I've roamed through this mailing list, StackOverflow, and generally googled all over, but I haven't found any *really* good setups. It's not mentioned in the GitSVN migration guide [4]. With the amount of people still using git-svn, I would've thought this topic would get some more attention.

Some say that creating a centralized bridge is generally bad idea, and it's better for all to just individually use git-svn as an SVN-client directly. But I'm sure if I had advocated this at my company, checkout/update performance wouldn't impress many, and I would still be the only git-user. Thanks to the git-svn bridge, we are now a handful Git-users, using Git for builds in Hudson, and steadily gaining traction.

So, to shape it in form of a question: What is the optimal git-svn bridge setup?

Thanks,

-Thomas
