The yocto-compat-layer script serves as a tool to validate the alignament
of a layer with YP Compatible Layers Programme [1], is based on an RFC
sent to the ML to enable automatic testing of layers [2] that wants to
be YP Compatible.
The tool takes an layer (or set of layers) via command line option -l
and detects what kind of layer is distro, machine or software and then
executes a set of tests against the layer in order to validate the
compatibility.
The tests currently implemented are:
common.test_readme: Test if a README file exists in the layer and isn't
empty.
common.test_parse: Test for execute bitbake -p without errors.
common.test_show_environment: Test for execute bitbake -e without errors.
common.test_signatures: Test executed in BSP and DISTRO layers to review
doesn't comes with recipes that changes the signatures.
bsp.test_bsp_defines_machines: Test if a BSP layers has machines
configurations.
bsp.test_bsp_no_set_machine: Test the BSP layer to doesn't set
machine at adding layer.
distro.test_distro_defines_distros: Test if a DISTRO layers has distro
configurations.
distro.test_distro_no_set_distro: Test the DISTRO layer to doesn't set
distro at adding layer.
Example of usage:
$ source oe-init-build-env
$ yocto-compat-layer.py LAYER_DIR
