What's New in Klocwork 2020.2

Klocwork 2020.2 launches an improved C# analysis engine with broader language support, improved accuracy, and new defect detection by up-to 30%*. This release also includes integrations for IDEs and CI/CD deployments, improvements to C++ analysis, and expanded coding standard support.

(*based on internally benchmarked OSS projects)

Major Update to C# Analysis Engine

Expanded C# language support, 64-Bit improvements, new project support, and increased analysis accuracy with up-to 30% more defect results*.

Full support for the C# 7.0 language specification has been added to Klocwork. New language features include:

  • Out variables as function arguments and discard out variables
  • Pattern matching
  • Tuples, tuple deconstruction, and discards in tuple deconstruction
  • Local functions
  • Binary literals and digit separators
  • Ref locals and returns
  • Generalized async return types
  • Expression bodied members for members formally returning void
  • Throw expressions

64-Bit improvements to the C# analysis engine allow effective analysis of large, complex code bases, and projects.

New build integration improvements now provide analysis results for mixed C/C++ and C# projects.

Added support for more Visual Studio project types such as .Net Core.

(*based on internally benchmarked OSS projects using these language features)

C++ Analysis Engine

  • Improved C++ defect detection for intraprocedural function pointer resolution and cases of function pointers that are returned directly or indirectly by function calls.
  • Improved support for rvalue references and override file mechanisms.
  • Upgraded KB customization for virtual methods allowing behavior definition to produce greater accuracy in your system.

New Jenkins Plugin

Our new Jenkins plugin provides an easy way for you to automate industry-leading static analysis as part of your Continuous Integration (CI) or Continuous Delivery (CD) pipeline.

The plugin provides Klocwork's Differential Analysis, which uses system context data from the server to analyze only the files that were changed, while providing a diff analysis as if the entire system were analyzed, resulting in the shortest analysis times.

CLion IDE Plugin

Use our new CLion desktop analysis plugin to quickly and easily detect and fix issues before check-in.

New and expanded standards coverage for Klocwork 2020.2:

  • CWE & CWE 2019 Top 25 – C#
  • AUTOSAR
  • MISRA
  • CERT – C/C++
  • Community Taxonomies – PCI DSS (C/C++, Java, and C#), Joint Strike Fighter Air Vehicle (C++), CERT (C/C++), Community Quality (C++)

New Vulnerability Checkers

The new checkers find defects for:

  • Dangerous implicit conversions
  • Dangerous coding practices
  • Out-of-boundary violations
  • Identifier name clashes
  • Tainted data
    • Buffer overflows using untrusted data
    • Excessive resource consumption using untrusted data

    • Buffer overflows
  • Uninitialized data
  • Unused variables
  • Exception handling
  • Dangerous casting
  • Banned APIs
  • General best coding practices

Klocwork Community

The Klocwork Community provides a framework for our users and professional services team to help shape the future of our coding standard coverage. By expanding on the certified Klocwork-developed checkers, we’re now providing access to sets of complimentary checkers and taxonomies that make the work of the wider community available within the product. All without the need to create and deploy your own.
