More rules to write C++17 compliant code

Hello C++ developers,

This is a second post related to the C++17 standard following the first announcement related to it in Dec 2020.

We continued our journey toward a good coverage of the C++17 standard and added 5 new rules.

  • S6026: “auto” should be used for non-type template parameter
  • S6010: “std::path” should be used correctly
  • S6029: Exception specifications should be treated as part of the type
  • S6000: “std::visit” should be used
  • S6020: The “_t” and “_v” version of type traits should be used instead of “::type” and “::value”

That’s it? No. A third release is coming and you can follow its progress here.

Nothing related to C++17, we also added 2 additional security rules:

  • S4790: Using weak hashing algorithms is security-sensitive
  • S1313: Using hardcoded IP addresses is security-sensitive

These rules are available now on SonarCloud and will be included in SonarQube 8.7 Developer Edition.
