| Summary: A tool for static C/C++ code analysis | |
This program tries to detect bugs that your C/C++ compiler don't see. Cppcheck is versatile. You can check non-standard code that includes various compiler extensions, inline assembly code, etc. Checking covers for example these errors: * Out of bounds * Uninitialized member variable 'classname::varname' * Using 'memfunc' on class * Using 'memfunc' on struct that contains a 'std::classname' * Class Base which is inherited by class Derived does not have a virtual destructor * Memory leak: varname * Resource leak: varname * Deallocating a deallocated pointer: varname * Using 'varname' after it is deallocated / released * Invalid radix in call to strtol or strtoul. Must be 0 or 2-36 * Overlapping data buffer varname * Unsigned division. The result will be wrong. * Unusual pointer arithmetic
GPL-3.0+
* Sun Feb 18 2018 aloisio@gmx.com
- 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.

* Results view: Suppress warnings through right-click menu
* Statistics: Added charts (shown if Qt charts module is enabled
during build)
