* cert.py: Add ENV33-C-EX1 exception
ENV33-C-EX1: It is permissible to call system() with a null pointer
argument to determine the presence of a command processor for the
system. [1]

* Handle different null-pointer constants
Format-string arguments are now marked to have `in` direction, except
for `scan`-functions (like `scanf`) where these arguments are explicitly
marked to have `out` direction.
Yesterday, I observed that some client with a wrong jobs setting
(only "-j") requested one package after another and always uploaded
results where it only said that the argument "-j" is invalid for
Cppcheck.
This check should avoid such cases where results are overwritten with
useless data and the server is kept busy for nothing.
* cppcheck.cpp: Check for JSON error when parsing addon .json files
This fixes that errors in JSON files given via `--addon=*.json` are
silently ignored and maybe only a part of the JSON file is used.
Now the error message which picojson can return is checked and a
corresponding error message is returned again by getAddonInfo().
* naming.json: Fix missing comma
* CLI: Fix naming violations detected by addon naming.py via naming.json
* Addon naming: Add argument for validating names of constants
* LIB: Rename functions/variables so they are valid, loosen naming rules
* GUI: Fix naming violations
The invalid code in Trac tickets #8750, #8753, #8756, #8762, #8764
and #8765 previously crashed cppcheck. Now it throws a syntax error
instead. Add some tests for these tickets.
The unused argument causes the new check for rule 2.7 to output an error
here.
I verified that the regression test still works without the unused
argument (misra.py would still crash).
Travis should be happy again.
* Add check for MISRA-C 2012 Rule 2.7 and test cases.
* Cast unused function parameters of some test patterns to "void".
* Fix function parameter void cast in "misra_17_6". Add comment to "misra_11_7_extra" to make all function parameter void casts look alike.
* fix syntax error for conversion operator for type with global namespace
* fix syntax error when taking address of operator function
* fix syntax error for using ::operator "" _a;
* fix syntax error for template<> void operator "" _h<'a', 'b', 'c'>() {}
* fix syntax error for operator in parentheses
Use Python 3 instead of Python 2 if addons are executed directly.
Running cert.py and misra.py against test/cfg/std.c.dump shows that
Python 3 needs only half the time compared to Python 2. I have tested
it repeatedly and the results are always the same. This is no surprise
at all. The memory footprint is very likely also significantly better
but i have not tested it.
This fixes https://trac.cppcheck.net/ticket/9456 (Tell the user that the
addons require Python) regarding the GUI. Whether it is useful/necessary
to add something similar for the CLI must still be checked.
