Release summary

  • New queries added for the following rule packages: Banned, Concurrency2, Preprocessor4
  • The following changes have been made for this release:
    • A3-8-1, A5-3-2, EXP54-CPP, STR51-CPP
      • All queries for these rules are now enabled by default. They previously disabled due to performance concerns.
  • Address a false positive flagged by cpp/autosar/using-directives-used for anonymous namespaces.
  • A10-2-1 - NonVirtualPublicOrProtectedFunctionsRedefinedQuery:
    • Fixed a typo that caused the derived class not to be displayed in the alert message
  • A10-3-3 - VirtualFunctionsIntroducedInFinalClassQuery
    • Fixed a typo that caused the introducing class not to be displayed in the alert message
  • Address a false positive flagged by cpp/autosar/external-linkage-not-declared-in-header-file for declarations that actually were in header files
  • Update the create_release.sh script to include query artifacts with Markdown help files
  • M3-2-1 - DeclarationsOfAnObjectShallHaveCompatibleTypes.ql
    • Use the type of the variable declaration entries instead of the variables, as variables may exist that have multiple entries with different types.
  • CON53-CPP - DeadlockByLockingInPredefinedOrder.ql
    • Optimized performance and expanded coverage to include cases where locking
      order is not serialized
  • CON52-CPP - PreventBitFieldAccessFromMultipleThreads.ql
    • Fixed an issue with RAII-style locks and scope causing locks to not be
      correctly identified.
  • Remove support for the anonymized pack because it is no longer necessary. The code scanning pack is superseding this pack.
  • Remove support for the LGTM pack because LGTM is EOL.
  • M5-18-1: Update the alert message to conform with our query style-guide.
  • CON53-CPP - DeadlockByLockingInPredefinedOrder.ql
    • Optimized performance by removing unneeded conditionals.
  • CON35-C - DeadlockByLockingInPredefinedOrder.ql
    • Optimized performance by removing unneeded conditionals.

Supported versions

  • The Code Scanning pack is supported when:
    • Using the CodeQL CLI version 2.7.6 in conjunction with a copy of the CodeQL standard library for C++ (github/codeql) set to the tag codeql-cli/v2.7.6.
    • Using the CodeQL Action or CodeQL runner with the codeql-bundle-20220120.
