Fixed usage of hasSideEffectsRecursive which was causes crashes
of rules 12.4 and 13.1.
Add more tests for these rules.
See trac ticket: https://trac.cppcheck.net/ticket/9487
Add some more tests for rule 10.1. They are given as examples in the
MISRA document. The 10.1 test that causes a false positive for 10.6 can be
found under the 10.6 tests.
Track ticket for false positive:
https://trac.cppcheck.net/ticket/9488
Trac ticket for the false negative:
https://trac.cppcheck.net/ticket/9489
* 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]
[1]: https://wiki.sei.cmu.edu/confluence/pages/viewpage.action?pageId=87152177
* Handle different null-pointer constants
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.
Rule 21.1 now doesn't report errors on usage of library functions
started from underscore (e.g. `_exit') and valid errno assignment.
See added tests for examples.
Fix R16.3 state machine which doesn't report errors in last case/default
statemenet. See added tests for examples.
Issue on trac: https://trac.cppcheck.net/ticket/8548
Version 1.88 changed the parsing of the MISRA rules file adding a
severity setting. This caused a regression in rule parsing.
In particular the following format used to parse cleanly and produce
rule output that would show the severity as part of the rule text.
Rule 1.2
Advisory
Rule text goes here.
Rule 1.3
Required
More rule text goes here.
As of 1.88 a file structured like above would parse as having no rules.
The problem is the use of blank lines as a rule delimiter. The
modified rule parser wants to see a rules formatted like below:
Rule 3.1 Required
R3.1 text.
Rule 4.1 Required
R4.1 text.
or:
Rule 1.1
Add this rule and parse to next, skipping empty lines.
Rule 1.2
Rule text.
Any rule text that did not fall into one of the above formats would
result in incomplete rule text parsing.
Change the parsing of the rule text file so that blank lines are ignored
instead of treating them as a delimiter between rules. Instead use the
start of the next rule as a delimiter for the end of the previous rule.
This allows both of the newer formats but also supports the behavior of
pre-1.88 versions.
Change units tests that were specifically forbidding the use of blank
lines to ones that allow blank lines.
* cert.py: Add '--quiet' option and test
Main sentinel also was required.
* travis.yml: Install pytest with --user
To avoid possible conflicts with system packages later.
* Quickfix
* Update addons structure. Make Y2038 addon works.
All addons are now located in same directory, where cppcheck-gui is
looking for them.
Y2038 addon has been updated to latest cppcheck version. Output is same
as 303622f01c commit as it described in
README: 303622f01c/addons/y2038/README.
* Clean up .travis.yml
* Update travis.yml paths.
* misra.py: Bring back -P argument for backward compatibility
* Fix paths
* Normalize dumpfile paths tpo cppcheck format
* Fixup 3 test.
* Add arguments regression test.
* Fixing travis build
* 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
* 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.
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.
* Added a new naming check addon. Also verifies variable and function prefixes
* Verification added to code
* added naming checks ng selftest to travis file
* Ensure zero exit value for tests if tests succeed
* Expected values adjusted
* Fixed copy and paste error
* 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
Add function isStandardFunction() that checks if the given function is a standard function.
Only when this function returns true for the currently checked rand() tokens it is reported as a violation.
Tests added for C and C++.
