When trying to convert a SVN repository that contained all our projects, I couldn’t find a good solution on the internet on one page.
The most usefull pages were:
https://github.com/nirvdrum/svn2git
http://book.git-scm.com/4_tracking_branches.html
I combined them together and described the steps below that will get the job done.
sudo adduser git nano /etc/group git:x:100:usera,userb,userc sudo mkdir /usr/local/git_root sudo chown git.git /usr/local/git_root sudo chmod 2770 /usr/local/git_root
Create authors.txt file for user mapping:
root = Root <root@example.local> usera = My name <myname@example.local>
To get a listing of all users in the repository:
svn log file:///development/svn_projects | grep -E "r[0-9]+ \| .+ \|" | awk '{print $3}' | sort | uniq
Lets install Git, ruby and ruby gems now for the subversion 2 git conversion
sudo apt-get install git-core git-svn ruby rubygems sudo gem install svn2git --source http://gemcutter.org sudo ln -s /var/lib/gems/1.8/bin/svn2git /usr/bin/svn2git
Specify path to repository or an optional deeper path:
svn2git http://svn.example.com/path/to/repo(/project/foo) --authors /path/to/authors.txt
Create bare repository
mkdir /tmp/foo cd /tmp/foo sudo su - git cd /usr/local/git_root/ umask 007 git clone --bare /tmp/foo foo.git cd foo.git/
Make sure permissions are set properly
git config core.sharedrepository 1
git config receive.denynonfastforwards true
find objects -type d -exec chmod 02770 {} \;
The “core.sharedrepository” flag tells git to keep everything group readable and writable.
The “receive.denynonfastforwards” flag makes sure that merges can’t happen when you push to the repository.
You have to do the merges on your local machine, and then push the result.
The subversion repository is successfully converted to a bare GIT repository now!
Test it with a checkout:
git clone ssh://localhost:22/usr/local/git_root/foo.git
Optional:
Checkout tracking branch:
git checkout -b 2.x-dev refs/remotes/origin/2.x-dev
Nice commands:
git branch git tag -l
