* misra.py: Allow executeCheck take multiple args
* misra.py: Fix R12.3 FN in variables declaration
Make rule 12.3 check detect commas in variables declaration code.
* Fix excluded lines
* Add support for global variables
* Fix FN when linenr from other file was excluded
* Add a few more tests
* Handle more cases
Handle additional cases to check commans in variables declaration
including:
* multiline variables declaration
* functions and structures initialized in the same line
* expanding macroses in initialization
* Fix FP in global struct initialization
* Add another test
* misra.py: R14.2: Verify for counter modification
Add additional check to detect modification of loop counter in loop
body. Related issue: https://trac.cppcheck.net/ticket/9490
Add small fix that treat all assignment operators defined in N1750
6.5.16 as has side affects. This will affects rules 13.1, 13.3, 13.5
and allow to catch some false negatives.
* Add tests for fixed FPs for R13.{1,5,6}
* fix
* use isAssignmentOp from cppcheck data
* remove unused set
* handle case with empty body or syntax error
* add test with outer variable
* Fix FP in nested loops, add tests
* Fix FP on outer variables
* Fixup false positives for not loop counters
* y2038 addon: Fix that check can never return True, add tests
At the beginning of `check_y2038_safe()` the variable `y2038safe` should
be initialized with `True` and only be set to `False` if there are any
issues. Otherwise it could never become `True`.
In the unit tests the return value of `check_y2038_safe()` is now
verified. But it does not yet work for the "good" example. The "good"
example also returns `False` since it finds warnings in the include
file. So this verification is marked with a "FIXME" comment.
* y2038 tests: Add "good" test file that does not use time functionality
The test file y2038-test-5-good-no-time-used.c does not use any time
functionality so the y2038 addon is not allowed to issue any warnings
and the check must return with `True` (code is safe).
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
