1. Project SCS a lightweight source control system for Windows platforms

2. The Need for Source Control Projects are not done by an individual Projects are not done at the same location This is especially true with open source and free software, where large projects have developers across the world.

3. The Need for Source Control Important drawbacks of no source control : Same file may be simultaneously edited by more than one developer, which will eventually cause consistency problems. Some previous working version of the software might be required (and storing all versions is a huge waste of space).

4. Similar Systems An excellent version control and source control system exists for Linux known as the CVS (Concurrent Versions System). A port of CVS for Windows called WinCVS is available (though not as mature). Visual SourceSafe is available for development with Microsoft Visual Studio.

5. Basic Architecture The SCS System consists of : The SCS Server (local or remote) acting as a repository SCS Clients SCS Server SCS Client ASCS Client B

6. Overview of Features Does not depend on the programming language or IDE used. Is quite lightweight and well-suited for medium sized projects. Supports integrated editing with the editor chosen by the developer. Allows regeneration of source files of previous versions but stores only the differences in each version (not implemented yet).

7. The SCS Server The server may be local or remote, and starts as soon as the Administrator logs in to the SCS system using the following interface :

8. The SCS Server (…contd.) This loads the view of the Projects in the SCS server where information about each project is displayed.

9. The SCS Server (…contd.) The view may be changed to show the details of every user along with the projects he/she is involved in :

10. The SCS Server (…contd.) There are modules for managing (adding, deleting, editing etc.) users and projects.

11. The SCS Client The client logs into the server using a dialog, which enables him to use a local or remote SCS server. The default port used is 2401 (which is the same tcp port used by cvs on Linux).

12. The SCS Client (…contd.) The client now successively selects the project, the files and the editor and starts working. At the end the changes are committed to the SCS server.

13. Instead of storing the entire files for all the versions it is desirable to store only the differences (using an algorithm similar to the one used in the UNIX “diff” utility). Automatic publishing of a project’s status on the web. Encrypting the network data transfer for security (using SSH is a possibility). Improvements Planned
