Configuration Management Configuration management is

Storing source code and documents in a central location

Allowing people to check out copies of the documents

Checking in documents Assigning version numbers to documents Locking documents so only one person can check

it out Sharing documents among several people and

resolving conflicts Assigning tags to major releases Creating branches off the trunk

The Repository Repository stores all

software in project Usually accessed via the

internet Any member of the group

can Checkin software Checkout software

The repository is a copy of the software on the user’s local disk

Versioning Every time software is checked in, a

version number is assigned

You can request any version of the software if you do not want the most recent version

Tags Can add a tag to any

combination of files Tag can be used to mark major

Branches Allow branches of the code base Each branch is a different version

Allows for Experimental development Development of different versions for

specialized markets

Subversion One of many open source source

code control systems Advantages

Can be run locally on a computer Can be run as a network server Has a client integrated into the

Windows file manager (Tigress SVN) Recognizes the structure of

directories Uses the same version number for

all files in a project, even if some of the files are not updated

Commits are atomic
