scm - git svn connect
The following allows you to reconnect a local clone of a remote svn repo assuming a git repo exists. In my case I have a backup of the remote svn repo but its a pure git repo without any git-svn meta data. Steven Walter provided the basic instructions here.
lcl ~/ $ git clone git://srv/amc.git amc lcl ~/ $ cd amc lcl ~/amc $ git svn init -s http://async-msgcomp.googlecode.com/svn lcl ~/amc $ rm -rf .git/svn lcl ~/amc $ cp .git/refs/remotes/origin/master .git/refs/remotes/trunk lcl ~/amc $ git svn fetch
At this point a git svn rebase should indicated “Current branch mastger is up to date.”
