Open source code as flawed as proprietary: Study

The source code for a newer version of the Apache Web server software is of the same quality as that of proprietary competitors at a similar stage of development, a new study has found.

The review compared version 2.1 of the Apache Web server software, which is used to house Web sites, with several commercial packages that handle the same chores. Reasoning, a company whose business is analyzing code quality, compared the recently released version with code of competitors at a similar stage of development.

The study found 0.53 defects per thousand lines of code for Apache, compared with 0.51 for the commercial software, on average. The comparable defect rate indicates that open-source software starts out as raw as proprietary software, but Reasoning said that ultimately open-source software has the potential to exceed proprietary software in quality. That's significant given the increasingly widespread use of open-source software such as Linux, OpenOffice desktop suite and the MySQL database.

"The open-source code seems to start at the same defect rate for early commercial code as well," Jeff Klagenberg, director of project management, said in an interview. "Over time, it can gain higher levels of quality. That appears to be because of the natural inspection process inherent in open source."
