I've played around with using git-svn to mirror a Git repo to an SVN repo, but I can't seem to do more than push the master changes to the SVN repos trunk.

Essentially what I've done so far is create an SVN repo with the standard layout (project-name/trunk, project-name/tags, project-name/branches) and then do a 'git svn init --stdlayout http://server/svn/project-name'. This sets up git-svn for the current Git repo and then I make any changes I want to in the Git repo and then push those to SVN via 'git svn dcommit', but this only seems to work for the pushing the current branch (usually master) to the SVN project's trunk folder.

What I'd like to be able to do is create Git tags and then push those to the SVN project's tags folder. I'd like to do the same for all of the branches, but that's not required. I need the SVN mirror to have trunk mirror the Git master branch and the tags mirror the Git tags.

Note: the SVN mirror would be read-only

  • I think github does something kind of like this, but AFAIK the way they do it is not open-source. – Tyler Jun 05 '11 at 20:01

You may try SubGit instead of git-svn.

SubGit provides read-write mirror functionality for Subversion and Git repositories. Among other things it converts both Git branches and tags into Subversion branches and tags directories.

See SubGit documentation and git-svn comparison for more details.

SubGit is a commercial product with some free options. One-time import is also free.

With git svn alone, you cannot mirror any Git operation back in the SVN. Only new commits done in mirrored branches can be safely dcommit back to SVN.

For a more complete round-trip, you could try git2svn to rebuild a SVN repo.
In the meantime, you can study this git svn workflow, even though tags aren't explicitly mentioned.
