Richard Purdie 2354250a95 bitbake: git: Use merge-base instead of log for testing if a commit is present
The current use of git log to check if a given revision is present can be
a little fragile.

For example if revision X was on branch A, and then later added to branch
B, the update checks would not notice this since they just check for X
being in the repository.

We also had some autobuilder corruption where an older packed-refs file
was copied over a new repository containing newer pack files. There
was no update to the refs file since the revision was present but
not accessible in any branch.

The correct fix is to check that the required revisions are present
on the specific branches. This patch does this using merge-base.

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.
