meta-codechecker's Introduction

meta-codechecker

A Layer to support CodeChecker as a frontent to clang static analysis

usage

This layer exposes a bbclass and the recipes needed to support inclusion of the tooling. Note that meta-clang is a requirement.

In a recipe enable:

To enable the layer within a single recipe, do add

inherit codechecker
CODECHECKER_ENABLED = "1"

In conf/local.conf

INHERIT += "codechecker"
CODECHECKER_ENABLED = "1"

options:

To generate a static HTML site as report do add:

CODECHECKER_REPORT_HTML = "1"

To generate a codeclimate compatible report do add:

CODECHECKER_REPORT_CODECLIMATE = "1"

The output will be in tmp/deploy/CodeChecker/*

To upload the results to the CodeChecker webserver (e.g. docker container) add:

CODECHECKER_REPORT_STORE = "1"
CODECHECKER_REPORT_HOST = "http://yourcodecheckerhost:8001/"
CODECHECKER_REPORT_ENDPOINT = "myproductname"
# ENDPOINT cannot have '.' or '+' or ' '  in the name !
#
# optionally have the endpoint created
#CODECHECKER_REPORT_ENDPOINT_CREATE = "1"

Note: The URL of the product to store the results for, in the format of 'http[s]://]host:port/'. (default: localhost:8001/Default)

Note: this was tested against the docker container docker pull codechecker/codechecker-web:6.15.2

output location

The output will be in:

check tmp/deploy/CodeChecker/*

meta-codechecker's Issues

move or delete dunfell branch

#11 restored compatibility with dunfell on current master branch.
However dunfell branch still points to old commit from over a year ago.
The branch should be moved to latest master (and keep being moved as master is being updated) or maybe removed to avoid the moving overhead.

Analysis in CodeChecker fails on AArch64

I tried a yocto build of R-Car Gen3 using meta-codechecker.
Build succeeded. However, many errors were counted in the Analyzer Statistics of Codechecker.

From the do_codecheckeranalyse log, it appears that clang does not support the "-mtune=cortex-a57.cortex-a53" flag and that analyzing has failed. An example is shown below.

...

Do you have any good ideas for a successful analysis?

[kirkstone] switch from distutils3-base.bbclass to the new setuptools3.bbclass

Currently we are use manually pip to install codechecker:

meta-codechecker/recipes-devtools/codechecker/codechecker_6.17.0.bb

Lines 33 to 36 in 2231a85

# CodeChecker use a native namespace package and can't be installed using
# setup.py install, so we can't simply ihnerit from setuptools3
# Instead, we must install using pip install .
# This code is inspired by the distutils3.bbclass

Next version of Yocto kirkstone now use pip instead of setup.py, as Python deprecated setup.py upstream.

The old behaviour is now in setuptools3_legacy.bbclass. The new setuptools3.bbclass use pip under the hood and should work with codechecker. This would allow us to drop our custom do_install step.

See this thread for more info: https://lore.kernel.org/all/CAAnfSTvjPeyJHjd-FiYoXmxPMaXM0AH9KMXm6n5ooJNfQp80Sw@mail.gmail.com/

This will also remove this warning on kirkstone:
WARNING: distutils-common-base.bbclass is deprecated, please use setuptools3-base.bbclass instead
