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.

How can I do this using git-svn?

Simply changing the svn url in the config file fails.

Answer 1

This handles my situation pretty well:

I cloned using the file:// protocol, and wanted to switch to the http:// protocol.

It is tempting to edit the url setting in the [svn-remote "svn"] section of .git/config, but on its own this does not work. In general you need to follow the following procedure:

1. Switch the svn-remote url setting to the new name.
2. Run git svn fetch. This needs to fetch at least one new revision from svn!
3. Change the svn-remote url setting back to the original URL.
4. Run git svn rebase -l to do a local rebase (with the changes that came in with the last fetch operation).
5. Change the svn-remote url setting back to the new URL.
6. Now, git svn rebase should work again.

Adventurous souls may want to try --rewrite-root.

Answer 2

You can see if the following works OK:

1. If svn-remote.svn.rewriteRoot does not exist in config file (.git/config):

   git config svn-remote.svn.rewriteRoot <currentRepositoryURL> 

2. If svn-remote.svn.rewriteUUID does not exist in config file:

   git config svn-remote.svn.rewriteUUID <currentRepositoryUUID> 

   The currentRepositoryUUID can be obtained from .git/svn/.metadata.

3. git config svn-remote.svn.url <newRepositoryURL>
