git-svn: what's the equivalent to `svn switch --relocate`?

Question

An svn repository I\'m mirroring through git-svn has changed URL.

In vanilla svn you\'d just do svn switch --relocate old_url_base new_url_base.

Based off of some of the other responses to this question, I have come up with a Ruby script that handles the git-svn relocating. You can find it at https://gist.github.com/henderea/6e779b66be3580c9a584.

It handles the relocate without checking out another copy, and it even handles the case where there are un-pushed changes in one or more branches (since that breaks the regular logic). It uses stuff from the git filter-branch answer (for the main logic) and the answer about copying branches from one instance of the repo to another (for copying branches with un-pushed changes).

I've been using this to relocate a bunch of git-svn repos that I have for work, and this version of the script (I've been through countless iterations) seems to work for me. It isn't super-fast, but it does seem to handle all of the cases I've encountered and result in a fully-relocated repo.

The script gives you the option to create a copy of the repo before making any changes, so you can use this option to create a backup. Creating a copy is required if you have un-pushed changes in any branches.

The script does not use any gems or other libraries not included in the normal MRI Ruby installation. It does use the readline and fileutils libraries included in MRI.

Hopefully my script will prove useful to someone else. Feel free to make changes to the script.

NOTE: I've only tested this script with git 2.3.0/2.3.1 and Ruby 2.2.0 on OS X 10.10 Yosemite (since that's the environment I use), but I would expect it to work on other environments as well. No guarantees about Windows, though.
