The current usage of EXPORT_FUNCTIONS is rather problematic since a class list (classes) is passed into the ast statement and cached as it was when first parsed. This class list may be different in other cases but is locked once in the cache. Worse, the construction of classes can be broken by exceptions during parsing at the wrong moments since the state of the parser is not always reset correctly. This can lead to leakage of other classes into the classes list. The current EXPORT_FUNCTIONS implementation looks at the last two currently inherited classes and sets up an indirect function call view the second last class inherited, e.g.: do_configure calls gnomebase_do_configure gnomebase_do_configure calls autotools_do_configure This intermediary doesn't seem to serve a useful purpose. This patch therefore makes builds deterministic and fixes various cache problems and indirection by removing the intermediaries and simply performing directly mapping for the cases where its needed.

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 = "") 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, patches against the various components
should be sent to their respective upstreams.
bitbake:
bitbake-devel@lists.openembedded.org
meta-yocto:
poky@yoctoproject.org
Most 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.
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.
