- Update to 1.85:
Changes from 1.83:
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.
Changes from 1.85:
General:
- We are modernizing the Cppcheck code. Support for MSVC 2010 and GCC 4.4 is dropped.
You now need a compiler that is at least as good as MSVC 2013 or GCC 4.6.
Checking improvements:
- New check: Suggest STL algorithms instead of hard-coded for loops
- New check: Warn about ineffective algorithms (same iterator passed)
- New check: Mismatching iterators used together in operators
- Container (STL/Qt/WxWidgets/etc) access out of bounds
- Improved the checkers that warns about same/opposite expressions, track variable values better.
- Variable scope: warn about references also
Graphical user interface:
- You can specify undefines in the project file dialog
- Fixed configuration of suppressions
- Windows: Fixed issue of wrong/no theme being applied to UI elements
Misra:
- support per file excludes from cppcheck

- Update to version 1.82
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
* More information in the cfg files
version 1.81
CPPCHECK:
* New warning: Check if condition after an early return is
overlapping and therefore always false.
* Improved knowledge about C/C++ standard, windows, posix,
wxwidgets, gnu
* Better handling of Visual Studio projects
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)
