So I have a few projects on SourceForge, but they’re all hosted via SVN. With all this distributed version control going on I thought I would like to get in on the action. I thought about moving to github, but what happens in 5 or 10 years when I want to move on to another revision control software? The name has a limited life expectancy. Anyway so I wanted to switch so I researched alot, this is the best information I found and this blog entry is basically a rehash specific to SourceForge (Because I didn’t find any good SourceForge specific information).
Note: For this tutorial you will want to change all occurrences of USERNAME to your user name for example “pilkch”, PROJECTNAME to your project name for example “breathe” and YOURFULLNAME to your full name for example “Chris Pilkington”.
First of all we need to download git and git-svn:
su yum install git git-svn
Now we are going to create our repo directory for holding our repositories:
cd ~ mkdir repo
Create a users.txt file to map our subversion users to git users:
USERNAME = YOURFULLNAME <USERNAME@PROJECTNAME.git.sourceforge.net>
As the other article says, we basically check out a svn directory as a git repository:
cd repo mkdir PROJECTNAME_from_svn cd PROJECTNAME_from_svn git svn init http://PROJECTNAME.svn.sourceforge.net/svnroot/PROJECTNAME/PROJECTNAME --no-metadata git config svn.authorsfile ../users.txt git svn fetch
Check that worked (Just read the last few changes to make sure svn history is present, you can hit spacebar to scroll back a page of history or two just to make sure):
From now on we can use git commands, first of all want to create a copy of the git-svn repository:
cd .. git clone PROJECTNAME_from_svn PROJECTNAME
PROJECTNAME/ now contains our “clean” repository and PROJECTNAME_from_svn can be deleted if you like. We now just need to add and push our local repository to the remote location:
cd PROJECTNAME git config user.name "YOURFULLNAME" git config user.email "USERNAME@users.sourceforge.net" git remote rm origin # This may not be necessary for you git remote add origin ssh://USERNAME@PROJECTNAME.git.sourceforge.net/gitroot/PROJECTNAME/PROJECTNAME git config branch.master.remote origin git config branch.master.merge refs/heads/master git push origin master
Now to check that this is working you can browse to the git page of your SourceForge project and there should be data in your repository. And we can clone our repository back again to check that everything is working.
git clone ssh://USERNAME@PROJECTNAME.git.sourceforge.net/gitroot/PROJECTNAME/PROJECTNAME
You may also want to ignore certain types of files, place a file called .gitignore in the root directory of your project and fill it with the patterns you want ignored:
.DS_Store .svn ._* ~$* .*.swp Thumbs.db
Now when we want to update we can do:
git commit -a -m "This is my commit message." # All changes to the local repository need to be committed before we try merging new changes git pull # Grab any changes from the main repository
Committing is slightly different:
git add .gitignore # For example we might want to add our new .gitignore file git commit -a -m "This is my commit message." # Note: Your commit has now only been staged, it is not in the main repository yet git push # Now it is pushed into the main repository
The last step is to remove your svn repository which for SourceForge is as simple as unchecking a checkbox on the Admin->Features page.
