"Yocto Project Compatible" [1] is a programme which requires you meet
specific criteria including going through an application process - it is
not sufficient simply to run the script we have created here and have it
produce no warnings/errors. To avoid people being confused by the fact
that this script uses the term "compatible" or variations thereof,
substitute usage of that word with "check" instead. The functionality of
the script is unchanged.

It is fairly common that BSP layers enable recipes when choosing
machines from that layer without checking whether the recipe actually
builds in the current distro. That breaks "bitbake world", retrieving
signatures and thus the test_machine_signatures test.
It's better to let that test continue with the signatures that can be
retrieved and report the broken world build separately. Right now, the
new test_machine_world iterates over all machines. More elegant and
useful in combination with a (currently missing) selection of which
tests to run would be to generate one test instance per machine. But that
is not straightforward and has to wait.
The "-k" argument alone was not enough to proceed despite failures,
because bitbake then still returns a non-zero exit code. The existance
of the output file is taken as sign that the bitbake execution managed
was not fatally broken.

Selecting a machine is only allowed to affect the signature of tasks
that are specific to that machine. In other words, when MACHINE=A and
MACHINE=B share a recipe foo and the output of foo, then both machine
configurations must build foo in exactly the same way. Otherwise it is
not possible to use both machines in the same distribution.
This criteria can only be tested by testing different machines in combination,
i.e. one main layer, potentially several additional BSP layers and an explicit
choice of machines:
yocto-compat-layer --additional-layers .../meta-intel --machines intel-corei7-64 imx6slevk -- .../meta-freescale
To simplify the analysis and limit the amount of output, mismatches
are sorted by task order such that tasks that run first are also
reported first. Following tasks for the same recipe and set of
machines then get pruned, because they are likely to be different
because of the underlying task (same approach as in
test_signatures). The difference here is that we get information about
all machines. The task order in the base configuration serves as
heuristic for sorting that merged list.
The test has already found issues in go-cross (depended on
tune-specific libgcc) and gdb-cross (had a tune-specific path
unnecessarily), so it is also useful to uncover issues that are not
caused by the BSP layer itself.

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
