minsize with argvalue for arg 2 which is a char pointer makes no sense.
Changing it to minsize with strlen for arg 2 results in false positives
(and i think false negatives too).
In std.c a test with a valid vsprintf usage is added that would result
in a FP when minsize with strlen for arg 2 would be used.
Additionally fix QString::sprintf() and QString::asprintf()
configurations.
Fix typo in quin[i]tptr.
Add warning for QString::sprintf and QString::vsprintf.
These functions are obsolete since Qt5, see
https://doc.qt.io/qt-5/qstring-obsolete.html
Remove TEXT() macro from windows.cfg and handle it internally where it
can be correctly simplified (Ansi vs. Unicode).
Also add handling of _TEXT() macro which is just a synonym for _T().
Add tests to verify correct function and macro simplification.
Add configuration and tests for LocalAlloc, LocalFree and some other
Local* functions.
LocalReAlloc is currently not configured as an alloc/dealloc function
(like realloc is not configured in std.cfg), i am not sure how to
correctly configure it.
Add missing returnValue types where appropriate and fixed a few wrong
ones.
Add some missing function names (mostly where the "std::" version of the
function is missing).
Add documentation for some functions where it is missing.
Remove functions that do not exist in the standard: std::array::clear,
std::vector::push_front.
Enhance *Equal/*Compare/*Copy/*Move/*Zero/*Fill memory functions to
catch buffer access out of bounds errors and ignored return values.
Replaced some function configuration by according defines as it is done
in windows to avoid redundant (and error prone) configurations.
Add configuration for G_UNLIKELY and G_LIKELY to avoid syntax errors
when these macros are used as condition without enclosing brackets.
Add test file to verify Gtk library configuration. Syntax check for the
test file is only done when Gtk+2.0 or Gtk+3.0 is found and working.
Tested on Cygwin and on Ubuntu 16.04.
Add Windows Socket 2 type/function configuration. There are still many
(microsoft specific) socket functions that are not yet configured.
Add configuration for GetUserName(), GetWindowText() and _fileno().
On Windows __wchar_t is a synonym for wchar_t, so an according define is
added.
wxDebugContext is only defined if wxUSE_DEBUG_CONTEXT is 1, so otherwise
just skip it for syntax checking because it will fail.
Change wxT to wxT_2 and add wxT_2 to the config to remove a warning
during syntax check and be more compatible with newer/older wxwidgets
versions.
Be more precise when replacing function like macros, fix redundant macro
definition for "_".
Add equivalent tests for the wide character string functions like they
are already done for the normal string functions.
Fixed some issues with the configuration of the wide character string
functions that arised through the tests and were already fixed for the
normal string functions.
Add test file for wxwidgets configuration, fix found issues and enhance
the cfg a bit:
Fix declarations in comments for wxLog* functions.
Merge the two wxTextFile::Create overloaded function configurations into
one that works for both now.
Removed use-retval attribute from wxBoxSizer::AddSpacer and
wxButton::SetDefault configuration since the functions have side effects
and there is no need to use the return value.
Add some function configurations, the macro _(str) and POD wxLogLevel.
Add function configurations with tests for:
GetLocalTime, GetSystemTime, GetLastError, SetLastError,
AllocateAndInitializeSid, FreeSid, HeapAlloc, HeapReAlloc, HeapFree,
HeapSize, HeapValidate and GetProcessHeap.
test/cfg/runtests.sh: Enable --inconclusive for the windows tests to
avoid some issues in the future.
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).
* posix library: Add strtok tests
In the posix library there is the same configuration for strtok but a
warning is added.
* posix.cfg: Remove redundant configuration for strtok, add comment.
[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.
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.
}
I intentionally removed the second access() configuraion because it was
missing the use-retval attribute. But calling access() without using the
return value is absolutely senseless.
I added tests to posix.c to verify the correct configuration of
access().
* Fix#7504: posix: open() was twice in configuration file
This fixes ticket #7504: Problems with the open function were not always
detected because the open function was twice in posix.cfg and only the
second configuration was used by cppcheck. Like suggested now only
one configuration is used and the third parameter has a default value
and is thereby optional.
use-retval has been removed to avoid duplicate warnings because the
alloc/dealloc configuration already warns about unused retval.
According tests to verify that open is configured
correctly now have been added to test/cfg/posix.c.
* posix.cfg: open(): Add TODO for use-retval configuration
