Migrating from SVN

If you have version control experience with SVN, here is what’s similar and what’s difference.

Workflow

At the beginning of learning git, you may follow the workflow of SVN. In the morning, you check out the code from the centralized repository. You work on your code. During lunch break or get off the work at evening, you check in the code and merge your changes into the centralized repository.

When you follow this SVN approach, you don’t get much benefits of using git. Git’s power comes from it’s distributed local repository. But it’s a good starting point to get familiar with the git command.

The similar

In collaboration, you need to push your code to a centralized server. Others pull and merged your code.

The difference

The repository is stored locally. The remote one is a duplicated one. Every local repository is a full working copy.

Technically

The merge is done in local instead of in the server.

Branch is essentially a pointer. Creating a new branch on a current state only creates a new pointer. In SVN, it copies a new folder and files to create branch.

Benefit of storing repository locally

  • You can work offline. You may be on train, on flight, on trip with no internet access. You’re disconnected and this is the best time of working. So you can continue on your code. Make changes and commits local. Exploring and experimenting freely.
  • Super fast response. Git encourages developers to create branches and experiment with code, because every changes are tracked. This confidence come from it’s fast response when creating and switching branches. This is because these repository operations are done locally. And because its mechanism optimists on branch switching.
  • Review before push. Git encourages creating branches and committing without worrying about losing the code. There are chances that the commits tree and branches become messy and complicated. Since all those commits are local only until we push those commits to a remote branch, we can re-organizing them before push them to remote.
