The Landscape of Concurrent Development

by Thomas Zimmermann

The version control archive CVS records not only all changes in a project but also activity data such as when developers create or update their workspaces. Furthermore, CVS records when it has to integrate changes because of parallel development. In this paper, we analyze the CVS activity data of for large open-source projects GCC, JBOSS, JEDIT, and PYTHON to investigate parallel development: How frequently do developers update their workspaces? What is the degree of parallel development? How many workspaces do developers have? How frequently do conflicts occur during updates and how are they resolved? How do we identify changes that contain integrations?
