Is it possible to have a Subversion repository as a Git submodule?

Question

Is there a way to add a Subversion repository as a Git submodule in my Git repository?

Something like:

git-svn submodule add https://svn.foo.com/svn/

I just went through this. I'm doing something similar to rq, but slightly different. I setup one of my servers to host these git clones of the svn repos I need. In my case I only want read-only versions, and need a bare repo on the server.

On the server I run:

GIT_DIR=.git git init
cd .git/
GIT_DIR=. git svn init svn://example.com/trunk
GIT_DIR=. git svn fetch
git gc

This sets up my bare repo, then I have a cron script to update it:

#!/usr/bin/python

import os, glob

GIT_HOME='/var/www/git'

os.chdir(GIT_HOME)
os.environ['GIT_DIR']='.'
gits = glob.glob('*.git')
for git in gits:
  if not os.path.isdir(git):
    continue
  os.chdir(os.path.join(GIT_HOME, git))
  if not os.path.isdir('svn/git-svn'):
    #Not a git-svn repo
    continue

  #Pull in svn updates
  os.system('git svn fetch && git gc --quiet')
  #fix-svn-refs.sh makes all the svn branches/tags pullable
  os.system('fix-svn-refs.sh')
  #Update the master branch
  os.system('git fetch . +svn/git-svn:master && git gc --quiet')`

This also requires fix-svn-refs.sh from http://www.shatow.net/fix-svn-refs.sh This was mostly inspired by: http://gsocblog.jsharpe.net/archives/12

I'm not sure why the git gc is needed here, but I wasn't able to do a git pull without it.

So after all this you can then use git submodule following rq's instructions.
