Cppcheck-1.82

We have released Cppcheck-1.82. The release notes are:

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
