Klocwork turns to open source to enhance static analysis

By David Worthington

April 18, 2008 — A static analysis software maker has turned to open source as a key part of its strategy to extend the versatility of its solution with community-developed concurrency checkers.

On Monday, Klocwork launched the Klocwork Checker Exchange for its customers to discover and share custom source code checkers that work with its Insight static analysis product. A toolchain called Checker Studio was released as well.

The checkers ferret out problems in code that has been run through Klocwork’s proprietary static analysis engine. Klocwork is attempting to kick-start Checker Exchange by releasing the source code for several families of its checkers starting with COM, MISRA and Symbian.

Gwyn Fisher, Klocwork’s CTO, said that Checker Studio would streamline the checker creation process. He described it as a set of work-along tools that developers can use as a reference base as they work in their IDE of choice.

Eventually, Checker Studio will evolve into a full Eclipse-derived IDE to further simplify checker development. “We always had APIs for people to pick up themselves, but there was a high learning curve and high degree of [Klocwork’s] investment. Now people outside of Klocwork can do it,” said Fisher.

The company views Checker Exchange as an opportunity to engage its customers while protecting its core intellectual property. “We created Checker Exchange for customers to share code, ideas, tips and tricks. They can create and find checkers that support new coding standards and platforms,” Fisher explained.

Klocwork will in turn incorporate community-developed checkers into its QA process and validate them with each subsequent release of its engine, he said. The checkers would be unlicensed software, restricted only by the fact that they only work with Klocwork’s analysis engine.

Fisher noted that Klocwork prefers a license-free caveat emptor environment where creators abrogate their IP rights, and checkers are used without warranty. Should Klocwork be put in a position to issue licenses, it would pick a license scheme that would be “good for everyone,” he said.
