Git+SVN at the Java User Group in Essen (ruhrjug)

Update: There's now a Xing signup for the event:

The event takes place on 14th of April, and starts at 18:00 in the Glaspavillon Campus Essen:

If you want to know the tricks of living with Git and Subversion in parallel, be there!

I'll be showing off all the steps, from getting started with git-svn, through the obligatory Git-Subversion mirror, to the final-migration-away-from-SVN. Hopefully there'll be time for showing off stuff I didn't get to at GearConf, as well as some good discussion.

Oh, by the way, if you've got any reference cases where you are also using git-svn, I would love to hear about it. I recently noticed that Gnu Cash are using it, and it would make me happy to hear if others have h…

As you may know, I'm a proponent of my own Git-SVN setup.

I remember trying to go down the path of a bi-directional repository, but always ran into problems. Here is how it could work:

However nice this would be to have, it can be very hard to achieve in practice:

git config receive.denyCurrentBranch ignore

You also have to automatically perform a git reset --hard in the syncing repo after each push (by some git hook?), because the work-dir is considered dirty when it is out of sync with the r…
