Fixes [YOCTO 15536] The postactions retrieval actions currently rely on scp executed individually on any file or directory expanded from TESTIMAGE_FAILED_QA_ARTIFACTS. Unfortunately, symlinks are not preserved with this mechanism, which lead to big storage space consumption. Things may go even worse if those symlinks create some circular chains. This mechanism then needs to be updated to preserve symlinks instead of following them during copy. There are multiple ways to do it: - create a local archive on the target and execute scp on this file - use rsync instead of scp for all files - create an archive and pipe it to ssh instead of storing it onto the target The first solution may create pressure on targets storage space, while the second assumes that rsync is installed on the target, which may not be true. So the third one is a compromise: tar is very likely present, at least through busybox, and no disk space is used on the target. Replace the current per-file scp call by a single call to tar run on the target. Retrieve the generated compressed archive directly from SSH output, and feed it to another tar process but on host, to uncompress and extract it at the same place as before.

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.

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.
