In a devshell, recent versions of git will complain if the repo is owned
by someone other than the current UID - consider this example:
------
bitbake -c devshell linux-yocto
[...]
kernel-source#git branch
fatal: unsafe repository ('/home/paul/poky/build-qemuarm64/tmp/work-shared/qemuarm64/kernel-source' is owned by someone else)
To add an exception for this directory, call:
git config --global --add safe.directory /home/paul/poky/build-qemuarm64/tmp/work-shared/qemuarm64/kernel-source
kernel-source#
------
Of course the devshell has UID zero and the "real" UID is for "paul" in
this case. And so recent git versions complain.
As the whole purpose of the devshell is to invoke a shell where development
can take place, having a non-functional git is clearly unacceptable.
Richard suggested we could use PSEUDO_UNLOAD=1 to evade this issue, and I
suggested we probably will see other similar instances like this and should
make use of PATH to intercept via devshell wrappers - conveniently we already
have examples of this.
Here, we copy the existing "ar" example and tune it to the needs of git to
combine Richard's suggestion and mine.
As such we now also can store commit logs and use send-email with our user
specific settings, instead of "root", so in additon to fixing basic
commands like "git branch" it should also increase general usefulness.
RP: Tweaked the patch so the PATH change only applies to the devshell task
and is a generic git intercept rather than devshell specific.
RP: Also apply the PATH change to do_install tasks since that also runs under
fakeroot and several software projects inject "git describe" output into
their binaries (systemd, iputils, llvm, ipt-gpu-tools at least) causing
reproducibility issues from systems with different git versions.

Poky
Poky is an integration of various components to form a pre-packaged build system and development environment which is used as a development and validation tool by the Yocto Project. It features support for building customised embedded style device images and custom containers. There are reference demo images ranging from X11/GTK+ to Weston, commandline and more. The system supports cross-architecture application development using QEMU emulation and a standalone toolchain and SDK suitable for 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 BSP layers which extend the systems capabilities in a modular way. Many layers are available and can be found through the layer index.
As an integration layer Poky consists of several upstream projects such as BitBake, OpenEmbedded-Core, Yocto documentation, the 'meta-yocto' layer which has configuration and hardware support components. These components are all part of the Yocto Project and OpenEmbedded ecosystems.
The Yocto Project has extensive documentation about the system including a reference manual which can be found at https://docs.yoctoproject.org/
OpenEmbedded is the build architecture used by Poky and the Yocto project. For information about OpenEmbedded, see the OpenEmbedded website.
Contribution Guidelines
The project works using a mailing list patch submission process. Patches should be sent to the mailing list for the repository the components originate from (see below). Throughout the Yocto Project, the README files in the component in question should detail where to send patches, who the maintainers are and where bugs should be reported.
A guide to submitting patches to OpenEmbedded is available at:
https://www.openembedded.org/wiki/How_to_submit_a_patch_to_OpenEmbedded
There is good documentation on how to write/format patches at:
https://www.openembedded.org/wiki/Commit_Patch_Message_Guidelines
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:
OpenEmbedded-Core (files in meta/, meta-selftest/, meta-skeleton/, scripts/):
- Git repository: https://git.openembedded.org/openembedded-core/
- Mailing list: openembedded-core@lists.openembedded.org
BitBake (files in bitbake/):
- Git repository: https://git.openembedded.org/bitbake/
- Mailing list: bitbake-devel@lists.openembedded.org
Documentation (files in documentation/):
- Git repository: https://git.yoctoproject.org/cgit/cgit.cgi/yocto-docs/
- Mailing list: docs@lists.yoctoproject.org
meta-yocto (files in meta-poky/, meta-yocto-bsp/):
- Git repository: https://git.yoctoproject.org/cgit/cgit.cgi/meta-yocto
- Mailing list: poky@lists.yoctoproject.org
If in doubt, check the openembedded-core git repository for the content you intend to modify as most files are from there unless clearly one of the above categories. Before sending, be sure the patches apply cleanly to the current git repository branch in question.
