Study shows open-source code quality improving

23. September 2009
The overall number of defects in open-source projects is dropping, a new by vendor Coverity has found.

Coverity, maker of tools for analyzing programming code, received a contract in 2006 from the U.S. Department of Homeland SecuritySecurity to help boost the quality of open-source software, which is increasingly being used by government agencies. Alles zu Security auf

The vendor has set up a Web site through which open-source projects and developers can submit code to be analyzed. The vendor assigns projects to a series of "rungs" depending on how many defects they resolve.

"Defect density" has dropped 16 percent during the past three years among the projects scanned through the site and some 11,200 defects have been eliminated, according to Coverity's latest report.

Four projects have been granted top-level "Rung 3" status, after resolving defects discovered during Rung 1 and 2, Coverity said. They are Samba, tor, OpenPAM and Ruby.

The Scan site has so far analyzed more than 60 million unique lines of code from 280 projects, according to Coverity. More than 180 projects have developers actively working to scan open-source projects.
