Klocwork has a static analysis tool (K7) which is similar to Coverity.They will run their tool on the Python source code on demand.The results are available at: https://opensource.klocwork.com/Currently, only Neal Norwitz has access to the analysis reports. Otherpeople can be added by request.K7 was first run on the Python 2.5 source code in mid-July 2006.This is after Coverity had been making their results available.There were originally 175 defects reported. Most of thesewere false positives. However, there were numerous real issues also uncovered.Each warning has a unique id and comments that can be made on it.When checking in changes due to a K7 report, the unique idas reported by the tool was added to the SVN commit message.A comment was added to the K7 warning indicating the SVN revisionin addition to any analysis.False positives were also annotated so that the comments canbe reviewed and reversed if the analysis was incorrect.
A second run was performed on 10-Aug-2006. The tool was tuned to removesome false positives and perform some additional checks. ~150 newwarnings were produced, primarily related to dereferencing NULL pointers.
