Creating a new Subversion branch from an existing local Git branch
When I'm coding I frequently have to work with Subversion repositories. I'm a Git user, so I use git-svn for this. Usually I do my work in local branches, using a fairly regular Git workflow, then checkout the integration branch, merge in my changes and git svn dcommit to push the code to Subversion.
Sometimes however I need to share changes that I've made on an existing local branch in my Git repository with a Subversion user before they're ready to integrate back into the mainline. It takes me a while to hunt down and work out exactly what to do whenever I want to do this, so here are the instructions for my future reference. Hopefully they help you too.
git checkout master
git svn branch <new_svn_branch_name>
git svn fetch
git branch -r # make sure <new_svn_branch_name> exists
git checkout -b tmp/svn-rebase-target <new_svn_branch_name>
git rebase --onto tmp/svn-rebase-target master <existing_git_branch_name>
# That should have checked out <existing_git_branch_name>.
git svn dcommit -n # This should say it'll commit to <new_svn_branch_name>.
git branch -D tmp/svn-rebase-target # clean up the temporary branch.
git svn dcommitThis time mainly I used comments on a blog post that asked how to do this. Thanks Björn Steinbrink and Cameron.
