Richard A. Smith 2b44fb57bc Loosen restrictions on MISRA rules text structure (#2157)
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.

.travis.yml: Check more Python scripts with pylint (#2019)
Use renamed pylintrc file that is only meant for Travis checks.

Check all Python scripts in 'addons', 'htmlreport' and 'tools'

Errors for `_socketobject` class are disabled, see
https://stackoverflow.com/questions/10300082/how-to-prevent-python-pylint-complaining-about-socket-class-sendall-method

Install imported modules `unittest2` and `pexpect` via pip.

Add "./addons" to search-path for modules because
"tools/compare-ast-clang-and-cppcheck.py" imports cppcheckdata.py from
addons. Pylint does not seem to evaluate
`sys.path.insert(0, '../addons')` in the script. So an `init-hook` is
necessary in pylintrc_travis.

Richard A. Smith f286325cec Fix per file excludes (#1437)
* 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

Richard A. Smith 4dbdc934b8 MISRA: Prevent exception on variadic functions (#1436)
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.
