Moving Subversion repositories to Git
Mostly FMI (for my information)... I've been wanting to check out git for a while and the time was right. I'll be moving one of my server accounts soon. That includes some Subversion repositories. It's not too hard to move svn to a new server but it turned out to be even easer to port it all to git. Here's what I did: [There are lots of ways to do this, but this worked for me...] > /git svn clone svn+ssh:!/!/user@pwizardry.com!/rest-of-svn-style-url/ This creates a new git repository in the current directory with the same name and all the contents of the Subversion repository, including all the revision history. A lot of stuff scrolls by listing every commit and every file involved. It died for me part way through with this encouraging message: *error: git-svn died of signal 13* which is from an unresolved bug. If you cd to the new repository and type > /git svn fetch/ it will continue where it left of. What I had when this was done was a git working copy. This includes all the diffs and objects that make a repository, plus a copy of the current versions of all files and directories. What I wanted was a "bare" repository on my server that doesn't have all the files. I'll use this to clone new working copies of my code where I will be working on it and then pushing changes back. For example, on my laptop: > /git clone ssh:!/!/munging.us!/xxx!/local!/git!/cell/ /[hack, hack]/ > /git commit -a -m "I hacked and hacked"/ > /git push ssh:!/!/munging.us!/xxx!/local!/git!/cell/ or just /git push origin/ Getting back to making a bare repostiry... It would be nice if /git svn/ took a --bare option, but it doesn't. The trick is to clone a new bare copy with a different name and blow away the original. Then rename the clone with the original name. > /git clone --bare cell cell.temp/ > /rm -rf cell/ > /mv cell.temp cell/ With all the warts showing in the first few git commands I typed, I had to wonder if it was ready for prime time! To be fair this was all in the git-svn command which, in the end, did an impressive job for me. One command and some cleanup (and a bunch web searching) did the trick. Bringing over the rest of my svn repositories was easy. git! [/items/hacks] permanent link
