* MISRA: Fix suppressed rules line numbers
Line numbers represented as strings in lxml ETree, but we use it in
integer comparison later.
* MISRA: Use standard library function instead file_prefix.
* MISRA: Use pytest's capsys for capturing, add suppressions tests.
* travis.yml: Update pytest version
* misra.py: Fixup load rules parser.
* misra.py: Report when rule text is missing in rule-texts file
* misra.py: Allow to skip misra checks not specified in rule-texts.
* misra.py: Remove top-level control flow.
Create separate class that stores settings, instead of global variables.
This is required to perform imports from misra.py for testing purposes.
* misra.py: Add simple pytest test for load rules.
* misra.py: Add document structure tests.
* misra.py: Exit after show rules table.
* misra.py: Add document structure tests.
* misra.py: Fixup import pitfall with python2
* misra.py: Minor fixes
* Add cmd parameter for choosing between C90 and C99
Misra specifies different requirements to the uniqueness of
macros/enums/variables depending on what C standard
that's being used.
* Add standards configuration to each dump file
Read standards config from misra addon to decide what rules to use.
* Posix as standard setting should be deprecated. Don't include this in the xml
* Rewritten to use a switch
* Modifiy check for MISRA rule 4.1 to avoid skipping constant character literal enclosed by single quotes.
Add test for MISRA rule 4.1 which contains non-compliant cases defined by MISRA C 2012 document.
* Moved additional test cases for MISRA rule 4.1 to appropriate test case section.
Without the `for scope in data.scopes:` loop, scope is not assigned anything.
From the context a loop over `data.scopes` could be intended. But other things like indentation would be possibly correct too. Not sure how this code should be.
We try this fix.
https://trac.cppcheck.net/ticket/8946
Add tests to travis script for verifying rule text loading.
Add dummy rule text files.
misra.py: Try to find a suitable codec for rule texts file.
* 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.
