Using CVS For Source Control

by Mike Griffin

Note, this tutorial assumes the BASH shell. You may need to modify some commands for other shells

Configure Lore Account for CVS

1. Add cvs to your execution path (Add it to your .bashrc)

export PATH=/p/cvs:$PATH

2. Create cvs repository, grant access to all members of project group

mkdir-shared ~/cvs [username]* [username]

3. Set CVSROOT equal to this repository (Add it to your .bashrc)

export CVSROOT=/homes/<mainusername>/cvs

4. Initialize the cvs repository

cd ~/cvs
cvs init

5. Import skeleton files into repository

cd <path to skeleton code>
cvs import -m "LabX Skeleton Code" labX labX start

Where labX is the current lab number

Begin working on code

1. Checkout code when beginning to work

cd ~/cs422
cvs checkout labX

2. Commit changes to the repository

cd ~/cs422/labX
cvs commit -m "changes made"

These instructions will work if you are working completely on the lore platform. If you would like to use Windows as your development platform, then the WinCVS instructions that follow will help you.

Configuring WinCVS for connection to Lore for CVS checkout and commit

1. Download the necessary programs
• WinCVS Make sure you download 1.3.17.2 Beta 17. There have been problems using a newer version
• PuTTY Version 0.55 or later
• Plink
• Pageant
• PuTTYgen
2. Configure PuTTY for SSH authentication to Lore

http://anders.fix.no/cvs/wincvs-ssh Save the key in ~/.ssh/authorized_keys2

3. Open WinCVS 1.3


4. In admin/preferences
• Authentication: SSH
• PATH is /homes/<username>/cvs

Where username is the username of the person who is hosting the cvs repository

• HostName: Name of the PuTTY session you created (Not the servername)
• UserName: Your username
• CVSROOT: (should be auto filled for you based on other values)
• Click on Settings

Check SSH Client and point it to the plink.exe program you downloaded

Begin working on code

1. Run pageant.exe
• Right-Click on pageant.exe icon in task bar (looks like a PC with a hat on it)
• Choose Add Key
• Point to the private key that you created with puttygen.exe
2. Run WinCVS

Click Remote, then click the command that you wish to execute
