Migrating from svn to git
Several tutorials have already documented the necessary steps for the conversion from svn to git (http://www.gitready.com/beginner/2009/02/04/converting-from-svn.html), so I won't reiterate any of that. What made our migration tricky were two things:
- SVN commits without authors
- No tags, branches, or trunk paths
The second was easy to fix actually. I didn't specify any flags for standard layout or tags/branches in the git svn clone command. The second took a little bit of guess work. Before I begin, I'll point out that I used the script (after cleaning up the leading and trailing white space)
svn -q log | grep ^r | cut -d '|' -f 2 | sort | uniq > authors.txt
as conveniently provided in the comments to one of the tutorials. Just to make life easy, I used the following VI macro to fill out the definitions in the file,
yeA= ^[pa <^[pa@domain.com>^[j0
I noticed a blank line in the file, which was generated because of commits to the repo with no user name -- literally just the empty string. Big deal, I just removed it. When I tried to run the "git svn clone" though, it puked when it got to those revisions:
$>git svn clone svn://svn.domain/project -A authors.txt
Author: (no author) not defined in authors.txt file
I googled and found a support article, http://support.github.com/discussions/repos/2690-authors-not-defined-on-svn-import, which didn't actually solve the problem, just avoided it. It turned out the fix was actually easier than I thought. I added the following line to the authors file:
(no author) = no_author
