  2. Why Version Control? • Reduce Risk • Facilitate Group Projects • Allows Experimentation • Personal Time Machine

  3. Risk Reduction • Distributed Code Base • Central Repository • Feature Retrieval • Do not forget to perform scheduled backups of your repository!

  4. Group Projects • Every gets a “current” copy of the full source • Can assist in code review • Don't Always have to wait on others • Merging - Not as bad as it sounds. • Conflicts - Can be as bad as it sounds. • Blame – As fun as it sounds! • Commit Often... But... • NEVER commit broken code to the trunk.

  5. Allows Experimentation • Peace of mind • I know my code is safe, what if I change x? • Branching • Try out new features without polluting trunk • Play in a sandbox

  6. Personal Time Machine • Remember when...? • Whoops, I deleted X! • Who changed that? Ask the log! • Why did I change that? Ask the log!

  7. VCS Choices • SubVersion • Stable and widely used • Reasonably straightforward • Cross Platform • Git • Local change tracking • Many more

  8. Usage • Create your Repository • Place your project in it • Add your project (Registers it with SVN) • Ignore (bin folder, class files, private settings) • Commit (Writes your changes to SVN) • Check for Modifications (See what changed) • Update (Pull the latest changes)

  9. Terminology • Working Copy • Trunk • Tag • Branch & Switch • Revert • Patch • Diff/Compare

  10. Have a Process • Make your changes • Update your working copy • Resolve any conflicts • Recompile and re-test! • Commit your changes
