Routine for converting svn to gitIf you have any other tips and or ideas, please let me know.

authors.txt

username1 = User Name <user@domain.com>
username2 = User2 Name <user2@domain.com>
otheruser = Other User <other_user@domain.com>
other = Developers <developers@domain.com>

gistfile1.sh

# In your SVN repository, run this command to get all your authors.
# This is a very important step. The rest of the process may silently fail otherwise.
# This is a nice easy way to get the authors for a SVN repo:
svn log --quiet | awk '/^r/ {print $3}' | sort -u

# Compile an authors.txt file using the format in the authors.txt file provided.
# Git needs this information while SVN only needs a username.

# Clone the repo, trunk, branches, tags
# Do not provide the trunk URL here, but provide the "root"
# repo URL that lies one level up from the trunk/tags/branches
# eg: https://myuser.myrepohost.com/myrepo/
# Enter the path to the Tags, Branches, and Trunk using -t -b -T respectively.
git svn clone <repository URL> --no-metadata -A authors.txt -t tags -b branches -T trunk <local git repository directory name>

# Fill in any empty commit messages.
# You'll need to do this for each branch by 
# checking out that branch and then running this:
git filter-branch -f --msg-filter '
read msg
if [ -n "$msg" ] ; then
    echo "$msg"
else
    echo "<empty commit message>"
fi'

# Checkout other branches by specifying the remotes/<branch name>
# Use `git branch -a` to see the local and remote branches
git checkout -b <branch name> <remote>/<branch name>

# Once done, then it might be a good time to nuke the svn info

# The Git Book reccommends this for converting the branches:
# http://git-scm.com/book/en/Git-and-Other-Systems-Migrating-to-Git
# Move the rest of the references under refs/remotes to be local branches:
git for-each-ref refs/remotes | cut -d / -f 3- | grep -v @ | while read branchname; do git branch "$branchname" "refs/remotes/$branchname"; git branch -r -d "$branchname"; done

# Clone the repo into a new repo and then remove the remote.
# This makes a new pristine repository with no remotes, but all of the history.
# http://nathanhoad.net/how-to-migrate-your-svn-repository-to-git
git clone converted-repo-folder-name new-repo-folder-name
cd new-repo-name
git remote rm origin

# You should now have a pristine copy of the Git repository
# with no remotes and all of your SVN history!

# Add your new remote
git remote add origin git@example.com:/repository-name.git

# Push your local branch (usually master) to the origin
git push origin master
