GIT versus SVN

GIT versus SVN

Summary of Comparison

  • Git is much faster than Subversion
  • Subversion allows you to check out just a subtree of a repository; Git requires you to clone the entire repository (including history) and create a working copy that mirrors at least a subset of the items under version control.
  • Git’s repositories are much smaller than Subversions (for the Mozilla project, 30x smaller)
  • Git was designed to be fully distributed from the start, allowing each developer to have full local control
  • Git branches are simpler and less resource heavy than Subversion’s
  • Git branches carry their entire history
  • Git provides better auditing of branch and merge events
  • Git’s repo file formats are simple, so repair is easy and corruption is rare.
  • Backing up Subversion repositories centrally is potentially simpler – since you can choose to distributed folders within a repo in git
  • Git repository clones act as full repository backups
  • Subversion’s UI is more mature than Git’s
  • Walking through versions is simpler in Subversion because it uses sequential revision numbers (1,2,3,..); Git uses unpredictable SHA-1 hashes. Walking backwards in Git is easy using the “^” syntax, but there is no easy way to walk forward.
