Currently if you do:
OVERRIDES = "z"
DEPENDS_prepend = "a "
DEPENDS = "b"
DEPENDS_z = "c"
d.update_data()
d.getVar("DEPENDS")
gives "a c"
d.update_data()
d.getVar("DEPENDS")
then gives "c"
This patch changes the behaviour such that at the time bitbake expands the DEPENDS_z
override, it removes "DEPENDS_z" from the data store. In the above example this would
mean that it wouldn't matter how often you call d.update_data(), you'd always get
"a c" back.
See the bitbake-devel mailing list for further discussion and analysis of the
potential impact of this change.

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:
