  • v1.84 Changes

    June 12, 2018

    🆕 New checks:

    • Same rhs expression used in consecutive assignments
    • ➕ Added more misra checkers
    • Function overrides base class function but is not marked with the override keyword

    👌 Improved checks:

    • Identical inner condition
    • Opposite expressions
    • Call to virtual function in constructor or destructor
    • Variable not initialized by private constructor
    • A class that has dynamic allocation needs copy constructor, assignment operator and destructor

    Misc:

    • 🐎 Various performance optimisations
    • 👍 Better support for C++17
    • ⚡️ --template=gcc format has been updated to match gcc output better.
    • We added a --template-location that can be used to format multiline messages.
    • ⚡️ Update --template so the piece of code with the warning can be shown
    • Symbol-based suppressions
    • XML based suppressions format

    ➕ Addons:

    • cert.py: Attempting to cast away const
    • misc.py: String concatenation in array initialization
    • misc.py: Passing struct to ellipsis function
    • misc.py: Function overrides base class function but is not marked with the virtual keyword

    👍 Compiling: We dropped support for some old compilers. From now on you need gcc 4.6 or later / visual studio 2013 or later / other compiler with c++11 support.

  • v1.83 Changes

    April 02, 2018

    💻 Command line:

    • 🛠 fixes in parser
    • 👌 Improved loading of platform files.

    GUI:

    • few minor improvements in user interface
    • Code preview
    • ➕ Added MISRA addon integration
    • Platform can be selected in project settings
    • 🛠 Fixed issue when loading xml results file

    ➕ Addons:

    • 👍 We are now officially releasing our MISRA addon. So far it supports MISRA C 2012.

  • v1.82 Changes

    January 14, 2018

    🐛 Bug fixes:

    • 👍 Better handling of namespaces
    • 🛠 Fixed false positives
    • 🛠 Fixed parsing of compile databases
    • 🛠 Fixed parsing of visual studio projects

    ✨ Enhancements

    🆕 New check; Detect mistakes when there are multiple strcmp() in condition
    Example:

    if (strcmp(password,"A")==0 || strcmp(password,"B")==0 || strcmp(password,"C"))

    There is a missing '==0', and therefore this condition is always true except when password is "C".

    🆕 New check; pointer calculation result can't be NULL unless there is overflow
    Example:

    someType **list_p = ...;
if ((list_p + 1) == NULL)

    The result for '(list_p + 1)' can't be NULL unless there is overflow (UB).

    🆕 New check; public interface of classes should be safe - detect possible division by zero
    Example:

    class Fred {
public:
void setValue(int mul, int div) {
  value = mul / div; // <- unsafe
}
...

    This check does not consider how Fred::setValue() is really called.
    If you agree that the public interface of classes should always be safe; it should be allowed to call all public methods with arbitrary arguments, then this checker will be useful.

    🛠 Fixed a few false negatives

  • v1.81 Changes

    October 07, 2017

    CPPCHECK:

    • 🆕 New warning: Check if condition after an early return is overlapping and therefore always false.

    GUI:

    • 🏗 Compile: Qt5 is now needed to build the GUI
    • Compile: New qmake flag HAVE_QCHART
    • Project: You can now run cppcheck-addons
    • Project: We have integrated clang-tidy
    • 🏗 Results view: Reload last results (if cppcheck build dir is used) when GUI is started
    • ⚠ Results view: Tag the warnings with custom keywords (bug/todo/not important/etc..)
    • ⚠ Results view: Shows when warning first appeared (since date)
    • ⚠ Results view: Suppress warnings through right-click menu
    • 🏗 Statistics: Added charts (shown if Qt charts module is enabled during build)
