Shlomi Fish once wrote a svn-push.c that according to him, will propagate changesets from one (networked) repository to another.

I found no one who actually got it to work so I dove in. Using the minimal-client.c as an example, I added an authentication piece. The authentication now works but seems like the routine crashes in make_reporter(), which is called by svn_ra_dav__do_diff. It also appears that the SVN guys made some wholesale changes in the reporter module - not sure if that is related. Hopefully someone will pay attention to this and comment.

I will post my version of svn-push.c to my public repo soon.
Here’s the svn-push.c that I modified. svn-push.c
