Object-Oriented Analysis & Design Subversion

Contents  Configuration management  The repository  Versioning  Tags  Branches  Subversion 2

Configuration Management 3  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 4  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 Repository Checkin / checkout

Versioning 5  Every time software is checked in, a version number is assigned  When software is checked out, you get the most recent version by default  You can request any version of the software if you do not want the most recent version

Checking In 6  Copies software from your computer to the repository  Assigns a version number to it  Makes the software to other people in the team  New files can be added to the project  Comments can be added  Can resolve conflicts if someone else modified the same document Repository

Checking Out 7  Copies the software from the repository to your computer  Can optionally lock the software so no one else can check out the same files Repository

Tags 8  Can add a tag to any combination of files  Tag can be used to mark major milestones  Can be used to retrieve all files used in a release Release 1.0

Branches 9  Allow branches of the code base  Each branch is a different version of the software  Allows for  Experimental development  Development of different versions for specialized markets

Subversion 10  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

Connecting to a Repository 11  Right click on a file in the file browser  Select Tortoise SVN | Repo Browser  Use https to specify repository  Enter user name and password

Adding Files to the Repository 12  You must place files under version control  Right click on file or directory in file browser  Select Tortoise SVN | Add...  This will let you add files to the project

Checking In 13  Once you have changed a file and want to place the changes in the repository  Right click on the file in the file browser  Select SVN Commit

Checkout 14 Right click and select checkout Fill in destination directory

Update 15  This will refresh the files in your copy to make sure they are up to date with the repository  Right click on file or directory in file browser and click  SVN Update
