CodeChecker support
###################
`CodeChecker <https://codechecker.readthedocs.io/>`__ is a static analysis infrastructure.
It executes analysis tools available on the build system, such as
`Clang-Tidy <http://clang.llvm.org/extra/clang-tidy/>`__,
`Clang Static Analyzer <http://clang-analyzer.llvm.org/>`__ and
`Cppcheck <https://cppcheck.sourceforge.io/>`__. Refer to the analyzer's websites for installation
instructions.
Installing CodeChecker
**********************
CodeChecker itself is a python package available on `pypi <https://pypi.org/project/codechecker/>`__.
.. code-block:: shell
pip install codechecker
Building with CodeChecker
*************************
To run CodeChecker, :ref:`west build <west-building>` should be
called with a ``-DZEPHYR_SCA_VARIANT=codechecker`` parameter, e.g.
.. code-block:: shell
west build -b mimxrt1064_evk samples/basic/blinky -- -DZEPHYR_SCA_VARIANT=codechecker
Configuring CodeChecker
***********************
CodeChecker uses different command steps, each with their respective configuration
parameters. The following table lists all these options.
.. list-table::
:header-rows: 1
* - Parameter
- Description
* - ``CODECHECKER_ANALYZE_JOBS``
- The number of threads to use in analysis. (default: <CPU count>)
* - ``CODECHECKER_ANALYZE_OPTS``
- Arguments passed to the ``analyze`` command directly. (e.g. ``--timeout;360``)
* - ``CODECHECKER_CLEANUP``
- Perform a cleanup after parsing/storing. This will remove all ``plist`` files.
* - ``CODECHECKER_CONFIG_FILE``
- A JSON or YAML file with configuration options passed to all commands.
* - ``CODECHECKER_EXPORT``
- A comma separated list of report types. Allowed types are:
``html,json,codeclimate,gerrit,baseline``.
* - ``CODECHECKER_NAME``
- The CodeChecker run metadata name. (default: ``zephyr``)
* - ``CODECHECKER_PARSE_EXIT_STATUS``
- By default, CodeChecker identified issues will not fail the build, set this option to fail
during analysis.
* - ``CODECHECKER_PARSE_OPTS``
- Arguments passed to the ``parse`` command directly. (e.g. ``--verbose;debug``)
* - ``CODECHECKER_PARSE_SKIP``
- Skip parsing the analysis, useful if you simply want to store the results.
* - ``CODECHECKER_STORE``
- Run the ``store`` command after analysis.
* - ``CODECHECKER_STORE_OPTS``
- Arguments passed to the ``store`` command directly. Implies ``CODECHECKER_STORE``.
(e.g. ``--url;localhost:8001/Default``)
* - ``CODECHECKER_STORE_TAG``
- Pass an identifier ``--tag`` to the ``store`` command.
* - ``CODECHECKER_TRIM_PATH_PREFIX``
- Trim the defined path from the analysis results, e.g. ``/home/user/zephyrproject``.
The value from ``west topdir`` is added by default.
These parameters can be passed on the command line, or be set as environment variables.
Running twister with CodeChecker
********************************
When running CodeChecker as part of ``twister`` some default options are set as following:
.. list-table::
:header-rows: 1
* - Parameter
- Value
* - ``CODECHECKER_ANALYZE_JOBS``
- ``1``
* - ``CODECHECKER_NAME``
- ``<board target>:<testsuite name>``
* - ``CODECHECKER_STORE_TAG``
- The value from ``git describe`` in the application source directory.
To override these values, set an environment variable or pass them as extra arguments.
