Question

I am seeing git svn fetch repeatedly retrieve the same Subversion revisions when it finds branches in my Subversion repository. We are using the standard Subversion reposit

If, at any point, the trunk of your repository existed at a different location in SVN, try specifying this location to additionally fetch in the repository's config file. For example:

[svn-remote "svn"]
... 
    fetch = project/trunk:refs/remotes/origin/trunk
    fetch = previous/location/of/trunk:refs/remotes/origin/trunk-old1
    fetch = another/location/of/trunk:refs/remotes/origin/trunk-old2
    ...

For the project I was importing, there were many branches and tags that had been created from these previous locations. Since these were branches/tags created from an 'unknown' place, git svn was throwing up its hands and just fetching all the history to find out. (This approach still required a full fetch for each location, but that was MUCH faster than a full history fetch for every tag)
