Tests that use bitbake("my-test-image") can run for a long time
without any indication to the user of oe-selftest about what's going
on. The test author has to log the bitbake output explicitly,
otherwise it is lost in case of test failures.
Now it is possible to use bitbake("my-test-image",
output_log=self.logger) to get more output both on the console and in
the XML output (when xmlrunner is installed). Example output:
2017-06-23 12:23:14,144 - oe-selftest - INFO - Running tests...

Because the implementation was already using threading, the same is
done to decouple reading and writing the different pipes instead of
trying to multiplex IO in a single thread. Previously the helper
thread waited for command completion, now that is done in the main
thread.
The most common case (no input data, joined stdout/stderr) still uses
one extra thread and a single read(), so performance should be roughly
the same as before.
Probably unintentionally, result.error was left as byte string when
migrating to Python3. OE-core doesn't seem to use runCmd() with split
output at the moment, so changing result.error to be treated the same
as result.output (i.e. decoded to a normal strings) seems like a
relatively safe API change (or rather, implementation fix).

Poky
====
Poky is an integration of various components to form a complete prepackaged
build system and development environment. It features support for building
customised embedded device style images. There are reference demo images
featuring a X11/Matchbox/GTK themed UI called Sato. The system supports
cross-architecture application development using QEMU emulation and a
standalone toolchain and SDK with IDE integration.
Additional information on the specifics of hardware that Poky supports
is available in README.hardware. Further hardware support can easily be added
in the form of layers which extend the systems capabilities in a modular way.
As an integration layer Poky consists of several upstream projects such as
BitBake, OpenEmbedded-Core, Yocto documentation and various sources of information
e.g. for the hardware support. Poky is in turn a component of the Yocto Project.
The Yocto Project has extensive documentation about the system including a
reference manual which can be found at:
http://yoctoproject.org/documentation
OpenEmbedded-Core is a layer containing the core metadata for current versions
of OpenEmbedded. It is distro-less (can build a functional image with
DISTRO = "nodistro") and contains only emulated machine support.
For information about OpenEmbedded, see the OpenEmbedded website:
http://www.openembedded.org/
Where to Send Patches
=====================
As Poky is an integration repository (built using a tool called combo-layer),
patches against the various components should be sent to their respective
upstreams:
bitbake:
Git repository: http://git.openembedded.org/bitbake/
Mailing list: bitbake-devel@lists.openembedded.org
documentation:
Git repository: http://git.yoctoproject.org/cgit/cgit.cgi/yocto-docs/
Mailing list: yocto@yoctoproject.org
meta-poky, meta-yocto-bsp:
Git repository: http://git.yoctoproject.org/cgit/cgit.cgi/meta-yocto(-bsp)
Mailing list: poky@yoctoproject.org
Everything else should be sent to the OpenEmbedded Core mailing list. If in
doubt, check the oe-core git repository for the content you intend to modify.
Before sending, be sure the patches apply cleanly to the current oe-core git
repository.
Git repository: http://git.openembedded.org/openembedded-core/
Mailing list: openembedded-core@lists.openembedded.org
Note: The scripts directory should be treated with extra care as it is a mix of
oe-core and poky-specific files.
