* addons: Reduce memory consumption
Parse dump files incrementaly using ElementTree.iterparse. Clean unused
resources during parsing. This method is explained in following
article: https://www.ibm.com/developerworks/xml/library/x-hiperfparse/
Memory consumption was reduced about 30% (measured with mprof),
execution time increased about 5% (measured with time utility).
More description available in PR.
* Switch to lxml and update iterparse routines
Use lxml module instead default xml.etree. Lxml provides convenient
wrappers around iterparse method that accepts `tag` argument. That
easer incremental parsing routines to select specific tags from roottree
like `dump` and `dumps`.
Element.clear() method was replaced by `lxml_clean` because lxml
keeps additional information to nodes that should be removed.
Added note about large consumption RAM on large dump files.
This commit doesn't solve this problem completely, but provides a way
to improve current parser to add incremental Configuration serialization
later.
* Working on iterative parser
* Added iterative Configurations parser
* fix
* Fix varlist iteration
* make sure that standards node was loaded
* 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]

* Handle different null-pointer constants
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.
* 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
* Roll back --recursive option
* Update addons section in manual
* 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
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++.
* added CLion project folder to .gitignore
* adjusted project name in CMakeLists.txt
* avoid warning when compiling "Debug" with Visual Studio via CMake
There was a GCC-style compiler flag in the common flags in compileroptions.cmake which caused the following warning:
cl : Command line warning D9002 : ignoring unknown option '-O0'
* compileroptions.cmake: restored original formatting
* some small *.py script cleanups
With multiple configurations, option --dump only dumps
the last configuration.
Fix it to dump every configuration.
Also update all Python addons so that they can handle
multiple-configuration dumps.
Additionally run autopep8 on addons/*.py.
The results of 'make test' before and after applying
this commit are identical.
