![]() When rewriting the do_rm_work injection, do_rm_work_all had been removed because it seemed obsolete, as do_build now always triggers do_rm_work. However, do_build does not get triggered for all recipes and thus do_rm_work was not called for recipes that got built only partially. For example, zlib depends indirectly on zlib-native:do_populate_sysroot. Because of that dependency, zlib-native got compiled, but do_rm_work was never called for it. Re-introducing do_rm_work_all fixes that by making do_build depend on do_rm_work_all, which then recursively depends on do_rm_work of all dependencies. This has the unintended side-effect that do_rm_work then also triggers additional work (like do_populate_lic) that normally doesn't need to be done for a build. This seems like the lesser evil, compared to an incomplete cleanup because it mostly enables the lighter tasks after do_populate_sysroot. The real solution would be to have two kinds of relationships: a weak ordering relationship ("if A and B are enabled, A must run before B, but B can also run without A") and hard dependencies ("B cannot run unless A has run before").

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.
