Source Code Revision Control
Working on any project, it's always a good idea to use some kind of source code revision control
system. Two popular for source code revision are Subversion and CVS.
Subversion
In the following examples, we assume a user on the Unix system with user name adam.
Create the repository
adam@hamberg: cd /home/adam adam@hamberg: mkdir svn adam@hamberg: svnadmin create /home/adam/svn/repos
Now you should have a new Subversion repository:
adam@hamberg:ls -l /home/adam/svn/repos/ conf/ dav/ db/ format hooks/ locks/ README.txt
Import a Project
Suppose you have started a project with the following directory layout:
adam@hamberg: ls /home/adam/src/aibo branches/ tags/ trunk/
This is the recommended directory layout for Subversion with a trunk directory to hold the "main line" of development, a branches directory to contain branch copies, and a tags directory to contain tag copies.
Lets assume you have the following files in the trunk:
adam@hamberg: ls /home/adam/src/aibo/trunk bar.c foo.txt README
You can now import the source tree:
adam@hamberg: svn import /home/adam/src/aibo file:///home/adam/svn/repos/some/project/name -m "Initial import" Adding /home/adam/src/aibo/trunk Adding /home/adam/src/aibo/trunk/foo.txt Adding /home/adam/src/aibo/trunk/bar.c Adding /home/adam/src/aibo/trunk/README Adding /home/adam/src/aibo/trunk/branches Adding /home/adam/src/aibo/trunk/tags Committed revision 1.
This means you imported all files and directories found in {/home/adam/src/aibo} and placed them under the directory some/project/name within the repository. You can check that the import worked:
adam@hamberg: svn list file:///home/adam/svn/repos/some/project/name branches/ tags/ trunk/ adam@hamberg: svn list file:///home/adam/svn/repos/some/project/name/trunk README bar.c foo.txt adam@hamberg:
Access the Repository
In the following examples we assume a user on one of the lab computers (Ubuntu) with user name eve.
The computers in the AIBO lab are not part of the same network as the UNIX-system. To access the repository we must tunnel over SSH using the svn+ssh:// URL scheme to connect:
eve@linux: svn list svn+ssh://adam@hamberg.it.uu.se/home/adam/svn/repos/some/project Password: README bar.txt foo.c name/ eve@linux:
Check Out a Project
Go to the directory to where you wish to create a working copy of the project:
eve@linux: cd /src/checkout
Check out the code:
eve@linux: svn checkout svn+ssh://adam@hamberg.it.uu.se/home/adam/svn/repos/some/project Password: A project/name A project/name/trunk A project/name/trunk/foo.txt A project/name/trunk/bar.c A project/name/trunk/README A project/name/branches A project/name/tags A project/bar.txt A project/foo.c A project/README Checked out revision 1.
CVS
If you want to create a CVS-repository for temporary use or for a short time, as for example for this course, you can create a group CVS-repository on one of the team members UNIX account:

The CVS-server provided by the department (system support) is reserved for repositories with more long-term use like projects or when external users without UNIX-accounts must have access.
