1. Source Code Repository Restructuring
Current Situation:
Multiple accelerator-related software projects are in
isolated repositories.
Those repositories are scattered across the lab network.
Support for storage of binary files is not optimal.
These factors combine to be problematic for development.
Sharing common code may soon be cumbersome and / or
dangerous.

2. Source Code Repository Restructuring
A Solution:
Central repository to house all accelerator code
development and documentation.
Migration from CVS to SVN technology
Reorganization of this master repository to better reflect
the structure of development efforts and resources
Accelerator Computing Meeting – Friday, 26 January 2007

3. Central Repository
In an accessible location for online and offline systems
Contains all accelerator-related code and documentation
Common code available to all inter-dependent projects
This will feed multiple build systems
- Take advantage of recent CPU additions and ample project disk space
Allows for consistent cross-project code tagging
Simplified mgmt. of possible offsite access for collaborators

4. Migration to SVN:
SVN offers flexible approach to repository management.
Internal structure can be changed at any time to fine-tune
the organization. History of changes saved as well.
Handles binary file storage gracefully
- .doc, .dwf, & other proprietary document formats
Several client interface options
CESRV will continue to be served via CVS due to VMS
client issues.
- This may change if SVN can be made to work under VMS.

5. Reorganization of Repository:
Repository organized to reflect hierarchical and shared
nature of cross-project development efforts
CESR online / offline
- simulation
- control system
- lattices
ERL online / offline
- layout files
- EPICS
ILC
CESR-TA
Other projects
Implement Tagging standards
- releases
- branches
- merging across projects
