The checker does not care if it's a header or source file. So I guess these tests were added to test
some parsing problem. Nowadays, #line is removed by simplecpp::preprocess, but there is no proper
testing for it in simplecpp.. I will add some testing for #line asap.
It is possible to define default template parameter values in forward
declarations and not define any in the actual declaration. Cppcheck
ignores forward declarations and only uses the default values in the
actual declaration so default values in forward declarations are copied
to the actual declaration when necessary.
* insecureCmdLineArgs: Fixed FN in case strdup() copies argv[].
* Formatted the code. There are no functional changes intended.
* Changes due to review comments from Daniel.
* Identify return conditions in multiconditions
* Improve error messages
* Check return statements are always true or false
* Add more tests for FPs
* Fix FP when returning const like variables
* Fix FP when returning pointers or classes
* Fix FP with member variable access
* Check non-local variables
* Use simplematch
* Check for null
* MISRA: Allow printing of the suppressed rules to the console
--show-suppressed-rules will print rules in the suppression rule list to
the console sorted by rule number.
* MISRA: Correct rule suppression for entire file scope
The entire file scope suppression check was checking for the rule item
list to be None instead of looking for None as an entry into the list.
Correct this check and modify the documentation to explicitly state that
an entry of None in the rule item list will set the scope for that
suppression to be the entire file.
* MISRA: Tests for checking per-file rule suppressions
To run:
../../cppcheck --suppressions-list=suppressions.txt --dump misra-suppressions*-test.c
python ../misra.py misra-suppressions*-test.c.dump
There should be no violations reported
* MISRA: Allow ignoring a prefix from file paths when suppression matching
For environments that run cppcheck from the build system cppcheck may be
passed a filename that is a complete path.
Often this path will include a portion that is specific to the developer
or to the environment where the project is located.
The per-file suppression rules do filename matching based on the
filename passed to cppcheck. To match any path information also has to
be included into the suppressions file provided to cppcheck via the
--suppressions-list= option.
This limits the usefulness of the per-file based suppressions because
it requires the suppression to be customized on a per instance basis.
Add a option "--file-prefix" that allows a prefix to be excluded from
the file path when doing the suppression filename matching.
Example.
Given the following structure:
/test/path1/misra-suppressions1-test.c
/test/path1/misra-suppressions2-test.c
specifying --file-prefix /test/path1 will allow the use of
misra-suppressions1-test.c and misra-suppressions2-test.c as filenames
in the suppressions file without leading patch information but still
match the suppression rule.
* MISRA: Tests for --file-prefix option
To run:
../../cppcheck --suppressions-list=suppressions.txt \
--dump misra-suppressions*-test.c \
path1/misra-suppressions*-test.c
python ../misra.py misra-suppressions*-test.c.dump \
path1/misra-suppressions*-test.c
There should be no violations reported
Functions with variadic arguments trip an exception in the MISRA checker
because some of the token is None and does not have some of the members
the code is expecting.
Prevent this by checking to see if the token is None and skipping the
code that tries to use that value.
Dynamic memory allocation was used for a XmlReportV2 object
in the function “ResultsView::readErrorsXml”.
This object was put on the stack instead so that this software
became a bit safer and more efficient.
