y2038 addon: Fix that check can never return True, add tests (#2417)
* 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).

Check for JSON error when parsing addon .json files + fixes (#2374)
* cppcheck.cpp: Check for JSON error when parsing addon .json files

This fixes that errors in JSON files given via `--addon=*.json` are
silently ignored and maybe only a part of the JSON file is used.
Now the error message which picojson can return is checked and a
corresponding error message is returned again by getAddonInfo().

addons: Change shebang to use Python 3 instead of Python 2 (#2361)
Use Python 3 instead of Python 2 if addons are executed directly.
Running cert.py and misra.py against test/cfg/std.c.dump shows that
Python 3 needs only half the time compared to Python 2. I have tested
it repeatedly and the results are always the same. This is no surprise
at all. The memory footprint is very likely also significantly better
but i have not tested it.

Georgy Komarov 3bd126486f addons: Clean up and clarify addons usage. (#2359)
* addons: Add '--recursive' arg. Clean up and clarify errors messages.

This commit introduce '--recursive' option for cppcheck addons.
Iff this option is set addon will recursively traverse directories in
given input files to find files with '.dump' suffix that would be
checked. Otherwise it will treat input directory as error (current
behaviour).

Add additional error handling with more clear error messages, clean up
the code.

* Add regex specifier

Georgy Komarov ff61d8e370 misra.py: Skip execution for globally suppressed checks (#2301)
These changes will improve misra.py execution time in the
case where we use globally suppressed checks. For example, when using
single MISRA rule and suppress others, we could get about twice the
execution speed, since most of `MisraChecker' class methods will not
be started at all.

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.

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.

Richard A. Smith ecd2ba2ece MISRA: Support Per file excludes from cppcheck (#1393)
* MISRA: Refactor many top level functions into a class

All the checker operations were implemented as individual functions.  In
order to share data globals were used.

By refactoring all these into class methods data can be shared between
them without resorting to globals.

This change is scope only.  No functional change for any of the methods.
Data is still shared via globals.

* MISRA: Refactor non-option globals into MisraChecker class

- Move all non-option global variables into the MisraChecker class

- Allows data to be shared among the class methods without needing
  globals.

- Move global VERIFY_EXPECTED to class variable verify_expected
- Move global VERIFY_ACTUAL to class variable verify_actual
- Move global VIOLATIONS to class variable violations
- Move global suppressRules to class variable suppressedRules
- Move global suppressions to class variable dumpfileSuppressions

This refactoring is in anticipation of parsing and using the
suppressions added into the dump file by cppcheck.

Only variable naming and scope changed.  No functional change for any of the
methods.

* MISRA: Restore original summary behavior

Version 1.84 introduced a regression in the behavior of the rule summary
output due to changes in the way multiple input files were handled.

The intended behavior of the summary was to output the total number of
violations after all files have been processed.

Commit aa831ce972 restored the input file
handling behavior but left summary behavior such that a summary output
was produced for each file that caused a violation instead of the total
number of violations after all files were processed.

Move the -verify logic up into the main loop so that the exit calls are
in the top level and restore the original behavior of the summary
output.

* MISRA: Support per file rule suppressions

Parse the suppressions list from cppcheck and extract MISRA rule strings from
the suppressions class by matching for errorId strings that begin with
'MISRA' or 'misra'.  Extract the MISRA rule from those strings by
looking for a '_' or a '.' to separate rule numbers.

Store the rule number, filename, line number, and symbol name from the
suppression entry into a structure that allows for dictionary lookups
by the rule number and then the filename.  All the line number
and symbol entries for that filename are are stored in list of tuples of
(line number, symbol name).  A rule entry that has a value of None for
the filename is treated as a global suppression for all files.  A
filename entry that has None for the rule items list is treated as a
suppression for the entire file. If the rule item list exist then it is
searched for matching line numbers.

Although symbol names are parsed and added int the list of rule items
they are not used for rule matching.  Symbol names can include regular
expressions.  Adding support for symbol names and regular expressions is
left as a future feature.

The existing global suppression method provided by the --suppress-rules
option is supported.  Those rules are added into the suppressions
structure as if they were provided by the suppressions list as global
suppressions. ie A rule with a None for the filename value.

rebnridgway 995b496ddf Add suppressions to the XML dump (#1166)
* Added parsing suppressions from dump xml.

* Added code to dump suppressions to an xml file

* Added declaration for dump function

* Suppressions will now be written to the xml file when a dump is requested

* Fixed syntax error

* Removed excess whitespace

* Fixed indentation to be consistent

* Fixed indentation to be consistent

* Fixed indentation to be consistent

* Added missing include for ErrorLogger::toXml

* Fixed suggestions from pull request #1166

Switched to using ranged for loop to iterate through suppressions.
Made the line number attribute optional, rather than 0 if not specified.  This means when Python deserialises it it will be None, which is more pythonic.

* Implemented checking suppressions in reportError

This modification expects suppressions and a function to be called to write a line of output to be passed in.  The function checks if any of the suppressions match the warning (with the new Suppression.isMatch function) and if so returns None.  This change maintains the old behaviour of returning the warning text, but adds the possibility of returning None if the warning was suppressed.

* Fixed code quality warnings

* Removed more extraneous whitespace
