Rewrite tinfoil as a wrapper around the UI, instead of the earlier approach of starting up just enough of cooker to do what we want. This has several advantages: * It now works when bitbake is memory-resident instead of failing with "ERROR: Only one copy of bitbake should be run against a build directory". * We can now connect an actual UI, thus you get things like the recipe parsing / cache loading progress bar and parse error handling for free * We can now handle events generated by the server if we wish to do so * We can potentially extend this to do more stuff, e.g. actually running build operations - this needs to be made more practical before we can use it though (since you effectively have to become the UI yourself for this at the moment.) The downside is that tinfoil no longer has direct access to cooker, the global datastore, or the cache. To mitigate this I have extended data_smart to provide remote access capability for the datastore, and created "fake" cooker and cooker.recipecache / cooker.collection adapter objects in order to avoid breaking too many tinfoil-using scripts that might be out there (we've never officially documented tinfoil or BitBake's internal code, but we can still make accommodations where practical). I've at least gone far enough to support all of the utilities that use tinfoil in OE-Core with some changes, but I know there are scripts such as Chris Larson's "bb" out there that do make other calls into BitBake code that I'm not currently providing access to through the adapters. Part of the fix for [YOCTO #5470].

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.
