From 28f555f6357ee0706847aff5b476b31b472b325c Mon Sep 17 00:00:00 2001 From: Martin von Zweigbergk Date: Thu, 1 Sep 2011 20:50:33 -0400 Subject: remote: write correct fetch spec when renaming remote 'remote' When renaming a remote whose name is contained in a configured fetch refspec for that remote, we currently replace the first occurrence of the remote name in the refspec. This is correct in most cases, but breaks if the remote name occurs in the fetch refspec before the expected place. For example, we currently change [remote "remote"] url = git://git.kernel.org/pub/scm/git/git.git fetch = +refs/heads/*:refs/remotes/remote/* into [remote "origin"] url = git://git.kernel.org/pub/scm/git/git.git fetch = +refs/heads/*:refs/origins/remote/* Reduce the risk of changing incorrect sections of the refspec by matching the entire ":refs/remotes//" instead of just "".

This does happen, but any remote-tracking branches starting with 'refs/remotes/o', such as 'refs/remotes/origin/bar', will also be renamed (to 'refs/remotes/foorigin/bar' in this case). Fix it by simply matching one more character, up to the slash following the remote name.
