Git is not Subversion

We decided in Spring 2011 to take Git in use as our only version control system. Original ambitious goal was to get rid of all existing Subversion and CVS repositories by the end of year 2012. That didn’t quite work out, we still have a lot of stuff in the old repositories. I can understand this with old not active repositories where nobody sees added value in moving them to Git, but a lot of active development is still done in Subversion repositories.

We’ve had several debates over the issue, latest was today. Some developers were complaining that Git is too complex, it is too difficult to learn to use correctly and it doesn’t explain what went wrong clearly enough. “With Subversion things are just a lot simpler and easier.” When digging deeper with this I found out some of the (Windows) developers are trying to use Git as they have used Subversion. So no use of local branches, no use of stashing, no use of rebasing… And they don’t want to use Git command-line, but GUI tools instead. Because that’s how they have always done.

I admit, if you use Git like you would use Subversion, Git is worse. It sucks. And if you don’t familiarize the fundamentals of distributed version control, Git will never be easy for you. It becomes the necessary evil of version control and you will never learn to use it properly. You start to hate it. And you won’t do anything in order to move ye old Subversion repositories to Git.

Git is not Subversion. Git is a distributed version control system and fundamentally different from Subversion, CVS or (dear god almighty) Source Safe. In order to properly learn Git, one should forget everything they’ve learned from source code version controlling using Subversion or CVS. Git is different. Even though it can be used like you would use Subversion, it is not meant for that. It is a powerful and sophisticated tool which helps you version control exactly the stuff you want. Git is your friend.

So give it another try, but this time start fresh. And uninstall that GUI tool or at least forget it. Git should be first learned using the command line version, it’s the best way to learn the usage properly.

Internet is full of resources for learning Git. Here’s for example one I presented in the Tampere Goes Agile conference in 2011: Up to speed with Git.
