Best practices for maintaining a subversion mirror?

Best practices for maintaining a subversion mirror?

[Oliver Charles]

Hi,

I just got myself a new server, and as I'm the major Git-using person
at my work, I'd like to set a mirror of our Subversion repository up
to hopefully convert a few more people. At the moment, I've done git
svn clone http://svn..., and then git clone --bare to make a --bare
version of this clone.

Now that I have this mirror, I have this entry in my crontab to update
it hourly:

0 * * * * cd /.git && /usr/bin/git --git-dir=. svn fetch &&
/usr/bin/git update-ref refs/heads/master refs/remotes/git-svn

This seems to be working nicely as a readonly interface, but when I
clone this repository (git clone git://foo/repo.git) - served via
git-daemon - I can't seem to get svn rebase to work on it, which means
I can't dcommit my changes back to Subversion.

Am I doing things generally the right way, or am I doing it completely
wrong? :-) Any tips appreciated!

First, make sure you aren't using the --no-metadata flag. git svn
rebase needs that metadata to rebuild its index.

Second, a simple "git clone" will not set up the svn remotes; you have
to do that by hand. This is what I do when I clone my svn mirror:

mkdir project
cd project
git init
git remote add origin git://mirror/project
git config --add remote.origin.fetch +refs/remotes/*:refs/remotes/*
git fetch
git svn init -Ttrunk svn://upstream/project
git config --add svn-remote.svn.fetch branches/foo:refs/remotes/foo
git config --add svn-remote.svn.fetch branches/bar:refs/remotes/bar
git reset --hard trunk
git svn rebase

Once you have it nailed down, you can put it into a script so all your
co-workers don't have to do that by hand too.

(Also, I quickly reset my cron job to run every five minutes; I found
an hour was way too long for my taste. YMMV, of course)
