git-svn clone takes on the order of 6 hours for us. I've had some luck
with "pre-clone/post-clone" steps that:
pre-clone (which is run after 'git svn clone')
1. create local branches for all 'remote' (svn) branches. This is so
'git clone' will create 'remote branches'. These are just
placeholders for the post-clone step:
git branch -r | grep -v tags | sed -rne 's, *([^@]+)$,\1,p' | while read branch; do
echo "git branch $branch $branch"
done | sh
2. create real git tags from all svn tags (we never branch from tags):
git branch -r | sed -rne 's, *tags/([^@]+)$,\1,p' | while read tag; do
echo "git tag $tag 'tags/${tag}^'; git branch -r -d tags/$tag"
done | sh
3. Now, with this repo, we create a "read-only" bare repo:
git clone --bare repo /somewhere/public/repo.git
4. cleanup the heads created from #1
git show-ref --heads | cut -d' ' -f 2 | grep -v master | while read branch; do
echo "git branch -D `basename $branch`";
done | sh
5. Now everyone git-clones from this repo, and runs 'post-clone' (below):
git clone git://somewhere/public/repo.git
We run 1-4 in a cron nightly.
After step 5, we 'post-clone':
1. put all 'origin/remote' branches (created in pre-clone #1) back to
refs/remote/<branch>
for i in `git-branch -r | egrep -v 'HEAD|master'`; do
echo "git update-ref refs/remotes/`basename $i` $i"
echo "git branch -D -r $i"
done | sh
2. delete origin/HEAD and origin/master
git update-ref --no-deref refs/remotes/origin/HEAD origin/master
git branch -D -r origin/HEAD
git branch -D -r origin/master
3. delete the origin repo from the config:
git config --remove-section remote.origin
git config --remove-section branch.master
4. re-init git-svn
git svn init -s <your svn repo>
5. rebase
git svn rebase
Now everyone has is working from the same git repo, and they have all
been reconfigured so that svn is the 'origin'.
