Linux code is the ‘benchmark of quality,’ study concludes - larsonpaorat

Fans of free and open source software (FOSS) may recollection a report from Coverity last year that base open source cypher typically has fewer defects per thousand lines of code than proprietary software code does.

Fast forward to this year, and the word is even more outstanding.

Following the analysis of more than 450 million lines of software code done the Coverity Scan service, Coverity's 2012 Coverity Rake Open Source Report, which was released Tuesday, concludes that "Linux remains the benchmark for prime."

'Differing dynamics'

Coverity's service, which was initiated in 2006 away Coverity and the U.S. Department of Mother country Certificate, has now become a widely accepted standard for mensuration the state of open source software quality.

Accordant to this year's results, unconcealed source projects with between 500,000 and 1,000,000 lines of code had an average 'defect tightness' of simply .44, whereas proprietary code scored at .98 for such projects. Defect density refers to the number of defects per 1000 lines of software code.

For projects with many than one million lines of code, on the other hand, defect concentration decreased to .66 in proprietary encipher merely increased all the way to .75 for open germ projects.

"This discrepancy crapper be attributed to differing dynamics within open source and proprietary growing teams, as well as the maneuver at which these teams follow out formalized development testing processes," Coverity explained.

For two years, both copyrighted and acceptant source users of Coverity's Scan Military service have demonstrated better quality than the constituted diligence standard mar density of 1.0.

Defect densities below 0.7

Particularly intriguing for fans of Linux, however, is that the free and explicit source operative scheme "remains a benchmark for quality," in Coverity's estimate.

"Since the original Coverity Scan report in 2008, scanned versions of Linux have consistently achieved a defect density of to a lesser extent than 1.0, and versions scanned in 2011 and 2012 demonstrated a defect density below .7," the company explained.

Whereas Coverity scanned to a higher degree 6.8 million lines of Linux inscribe in 2011 and constitute a defect density of .62, the 2012 report included a scan of more than 7.4 million lines of Linux code and found a defect density of .66.

Most recently, Coverity scanned 7.6 million lines of cipher in Linux 3.8 and found a desert concentration of just .59.
