Update: Since I wrote this, I found out the git-svnimport is deprecated. The good news is that the process is now much easier!

I started importing a bunch of our Rails plugins into GitHub this morning.

A couple of issues proved problematic:

1. Our plugins were in a single svn repository and not the typical trunk and branches setup:

   rails/plugins/acts_as_audited
   rails/plugins/acts_as_geocodable
   …
   rails/plugins/with_action
   

   To get this to work, you use the root of the repository as the path and pass -T with the path you want to fetch.

   git svnimport -T plugins/acts_as_audited http://source.collectiveidea.com/public/rails

   This is totally fine with git svn. Don’t worry about it. I strongly recommend putting each plugin (or project) into its own git repository, as it will make your git life easier.
2. Usernames in svn are stored just as our unix usernames (brandon, daniel). For git, I want to use our email addresses.

   For that, you make a file of all the authors in the format

   username = User's Full Name <email@addr.es>

   and pass -A path_to_author_file

   git svnimport -T plugins/acts_as_audited -A ./authors http://source.collectiveidea.com/public/rails

   git svn clone http://source.collectiveidea.com/public/rails/acts_as_audited -A ./authors

3. Finally, to save trouble, I want to create a new git repository. Trust me, its just easier. Pass in the path you want. -C some_path

   git svnimport -C acts_as_audited -T plugins/acts_as_audited -A ./authors http://source.collectiveidea.com/public/rails

That’s it! After that, you have a git copy of your repository and can push it to GitHub, or do whatever you want.

Here’s the final command for reference (I added -v for verbose):

<del>git svnimport -v -C acts_as_audited -T plugins/acts_as_audited -A ./authors http://source.collectiveidea.com/public/rails</del>
<ins>git svn clone http://source.collectiveidea.com/public/rails/acts_as_audited -A ./authors </ins>

git svnimport -v -C acts_as_audited -T plugins/acts_as_audited -A ./authors http://source.collectiveidea.com/public/rails

git svn clone http://source.collectiveidea.com/public/rails/acts_as_audited -A ./authors
