Sebastian 1ad22ae231 windows library: Add strlwr/strupr configuration, fixing tests (#1076)
Add configuration for the deprecated strlwr/strupr functions with
according warning.
test/cfg/windows.cpp: Added tests for strlwr and strupr. Moved function
call that does not return (FreeLibraryAndExitThread) to the end of the
function to fix analysis that was silently aborted at that point
(reported as issue #8378).

Sebastian 13f5a4ae29 runastyle.bat: Add optional cfg file formatting, cleanup. (#1073)
Add formatting of the configuration files (cfg/*.cfg) if the xmllint
binary is found.
Changed windows commands and arguments to uppercase to be consinstent.
Silenced the output of commands that is not interesting.
Tested with the xmllint binaries and libraries found here:

symboldatabase: Fix potential null pointer dereference (#1072)
There is a  potential `nullPointer` dereference in symboldatabase. This PR attempts to fix this. Additionally, this could be detected by Cppcheck as well. 

Here is a reduced and compilable testcase, where Cppcheck fails to detect a potential `nullPointer` dereference:

```
class Scope
{
public:
    bool bar();
    int *definedType;
};

int f(Scope *new_scope)
{
    int ret = 1;
    if (new_scope)
    {
        if (new_scope->bar())
        {
            if (!new_scope->definedType) {} // check for null
            ret = *new_scope->definedType; // dereference
        }
    }
    return ret;
}
```

Daniel Marjamäki 21a35de0d2 Tokenizer: Refactoring garbage check 2018-01-27 22:26:43 +01:00
David Hallas 4d18d3948f Fixes issue with case inside switch that is not a compound statement (#1031)
* Fixes issue with case inside switch that is not a compound statement was treated as garbage

This fixes an issue with the check for case keywords outside of switch
detection that would treat a case statement inside a switch that is not
a compound statement as garbage, but this is perfectly valid C++. This
construct is used in several libraries, i.e. Google Test.

* Tweak check and handle missing semicolon

Tweaks the check with feedback from danmar.
Handle the case where there is no semicolon and document it with a unit
test.

Sebastian 6b5805041b std.cfg: Fixed remaining functions found to be redundant (#1055)
[std::]strtoimax and [std::]strtoumax:
They were nearly completely duplicates, i removed the ones with
less/missing configuration.
std::basic_string::empty:
It was found to be redundant because very likely someone forgot to
change "empty" to "clear" when copy&pasting the function names. The
empty function in all these clear functions makes no sense, and the
clear function also was missing.
std::queue::empty and std::array:empty:
They were both twice in the same function name list.
std::string::size, std::wstring::size:
They were already configured with many other size functions above.
std::basic_string::size:
This entry was twice in the same function name list directly one after
another. Very likely one of them should be the length function, which
does simply the same but was missing in the std.cfg.

Sebastian d46cd46d0f windows.cfg: Add _countof macro configuration (#1047)
By telling cppcheck about the Microsoft Windows _countof() macro it is
now able to detect out of bounds array accesses like this:
wchar_t buf[10];
for(size_t i = 0; i <= (_countof(buf)); ++i) {
buf[i] = L'\0'; // (error) Array 'buf[10]' accessed at index 10, which
is out of bounds.
}
