Converting a repository from git to subversion

The general problem with doing conversions this direction is that Git repositories can contain more than just a linear history of revisions, as Subversion would expect. Multiple ancestries with divergent histories and frequent merge commits are all possible, which can't be easily represented in a Subversion repository.

For simple cases where you do have a linear history in your Git repository, you can use git-svn dcommit to push the lot up to an otherwise empty Subversion repository.

It's very easy to perform with SubGit.

$ svnadmin create svn.repo
$ subgit configure svn.repo
$ nano svn.repo/conf/subgit.conf to specify a path to your bare repository (you may use "git clone --bare <URL>" if you have none locally)
$ subgit install svn.repo

After conversion your SVN and linked Git repository will be in sync: every Git push will be translated to SVN commit and vice versa. To break translation run

$ subgit uninstall svn.repo

While translation SubGit will try to preserve commit dates, tags, ignores, merges, EOLs, branches and so on, as it is possible. I can't say the same about git-svn repository.
