For a while its been puzzling me why connman-gnome rebuilds as often as it
does. It turns out you can trigger this with a new checkout of the metadata.
The SRC_URI that is causing the problems is:
SRC_URI = "file://images/*"
and rather oddly the results in checksums for a file "." being added to
the tree, e.g.:
('.', 'ab48a68186f0e0f277c21ef4cb390b4b')
The problem is that when iterating files lists, the checksum variable can
become set yet we don't break the out from the for loop, which leads to
odd (and non-deterministic) entries being added into the file checksum list.
The exact item added probably depends on the order of items on the disk.
Before this change, bitbake-diffsigs on connman-gnome:do_fetch would report:
This task depends on the checksums of files: [
('connman-signal-03.png', 'f6c16aee57b37b73793a2f1dea433ffa'),
('connman-signal-02.png', 'ad0cd22710c097d8174121fc1023c3be'),

('0001-Removed-icon-from-connman-gnome-about-applet.patch', 'e2d8269357c1e8c84291606da24eea85'),
('.', 'ab48a68186f0e0f277c21ef4cb390b4b')]
Afterwards:
This task depends on the checksums of files: [
('connman-signal-03.png', 'f6c16aee57b37b73793a2f1dea433ffa'),
('connman-signal-02.png', 'ad0cd22710c097d8174121fc1023c3be'),
('connman-signal-01.png', '8842bd83d2fa9ba56480df34c727c629'),

('0001-Removed-icon-from-connman-gnome-about-applet.patch', 'e2d8269357c1e8c84291606da24eea85'),
('0001-Removed-icon-from-connman-gnome-about-applet.patch', 'e2d8269357c1e8c84291606da24eea85')]
which is correct and deterministic without the "." entry.

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, 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.
