In order to increase the quality of analysis for Unreal Engine projects, annotations for several hundred functions from the game engine were added to PVS-Studio C++ analyzer.

PVS-Studio analyzers for C, C++, C# and Java already provide coverage for more than a half of CWE Top 25 categories, and we plan on expanding this coverage in future releases.

We now provide a mapping for PVS-Studio rules with CWE Top 25 Most Dangerous Software Weaknesses list.

You can find more details on the Analyzer Best Warnings mode in our blog and documentation. In future releases we plan on expanding this new mode, as well as adding it to our other supported IDEs and analyzer integrations. Besides warning message levels, it takes into account a number of other criteria, which can be subdivided into the static (an average 'value' of an analyzer rule) and dynamic ones, based on the warnings generated on a particular source code base (such as, for example, the total number of warnings for a particular rule). In this new version of the analyzer, we developed a more sophisticated and precise algorithm of evaluating the reliability of warning messages. PVS-Studio have always grouped its warnings into 3 certainty levels, and these levels were usually used for prioritizing the most interesting ones when reviewing the analysis results - the best ones were expected to be on the 1st level.

The name of this new mode is Analyzer Best Warnings.

This release introduces, for the users of PVS-Studio plug-in for Visual Studio, a new way of checking analysis log for the most interesting warnings among all others found in an analyzed project.

More detailed information on innovations in various versions of the analyzer is presented below. Graph of increasing the number of diagnostics in PVS-StudioĪs you can see, we are actively improving the capabilities of the analyzer to detect new error patterns and at the same time are pushing the development of other tools :).
