Aegis

Transaction-based software configuration management system

Aegis is a transaction-based software configuration management system. It provides a framework within which a team of developers may work on many changes to a program independently, and Aegis coordinates integrating these changes back into the master source of the program, with as little disruption as possible. Some key features

• All operations on the repository are based on change sets.
• True configurations. All changes are reproducible snapshots. Every change set has a unique configuration identifier.
• Ability to rename files without losing their history.
• Binary files are supported.
• File meta-data are versioned. Aegis versions permissions also.
• Commits are truly atomic. No part of a commit takes effect until the entire commit has succeeded. Log messages are attached to the change set, not stored redundantly in each file.
• Access controls on lines of development branches. Creating a branch in Aegis can be accomplished with a single, fast command.
• Repository synchronization, geographically distributed development.
• Optimal performance for all users, local or remote no difference.
• Disconnected commits.
• Peer-to-peer architecture. Work may flow in without involving a master site.
• Costs are proportional to change size, not data size.
