Subversion Saves The Day

Subversion is a version control system that allows developers to track changes, rollback mistakes, and safely experiment without affecting the main codebase. It also enables developers to collaborate either individually as "lone wolves" or in teams of "dream teams". Key concepts include revisions, repositories containing all code, and individual working copies. Subversion is used via clients on various platforms and servers, and enables workflows for both individual developers and collaborating teams.
Subversion Saves The Day
- 1. Subversion Takes Back the Night How Version Control makes web development better
- 2. WHY? Track your changes to show them you really are working Rollback mistakes without rolling on your rifle in despair Experiment safely without borking the “real” code base Collaborate sanely with both “Lone Wolves” and “Dream Teams”
- 3. Key Concepts Revision: Group of files at same stage Repository Everyone’s stuff combined Working Copy Your own stuff Repository Your Working Copy Her Working Copy
- 4. Your Subversion Toolbox A Client Windows: TortoiseSVN OSX: SCPlugin Linux: the CLI, of course Lots of plug-ins for Editors / IDEs A Server Subversion on a local file system Apache: mod_dav_svn
- 5. Making a Repository Make an empty directory Create a repository there Add 3 directories: trunk branches tags (Subversion basically requires this) Create your directory for a working copy
- 6. Use Case: Lone Wolf Keeps Personal Repository on local File system Has a Hard Time Sharing Deploys Files to Web Server with: Capistrano Phing Ant Or simply “svn export” because he’s a lone wolf who doesn’t believe in the sanctity of build scripts
- 7. “Lone Wolf” Workflow Add Files to Repository Hack…hack… Commit to Repository Client: “What have you done for me today, Wolf?” Here you go: “svn log –r {2010-01-13}:HEAD”
- 8. Use Case: Dream Team Central Repository on Web Server Lots of loving, group-based development …each with his/her own working copy = FUN!
- 9. Dream Team Workflow Teammate: “I’ll do this part, you do that part and then we’ll merge!” You: “You bet, buddy!” Hack…hack… svn commit svn update svn status “ Oh No! A merge conflict” Diff it Edit it ‘ svn resolved index.php’ Re-commit
