Version Control System
Version control is a system that records changes to a file or set of files over time so that you can recall specific versions later.
Goals:
- Record edits
- Keep a change history
- Backup and restore
- Branching
- Ease of collaboration
Example software:
- GIT
- Subversion (SVN)
- CVS
GIT
- Distributed
- Open-source
- Scalable
- Fast
- Only stores differences between versions
Workflow
- Clone (copy to local computer)
- Modify/add/delete files
- Stage the files
- Commit locally
- Push changes to remote repository
- Pull to update local repository
Branching
- Master - holding the main working version
- Branching
- new features
- bug fixes
- trying out things
- Merge to bring two branches back together
