Changelog: ========= -BREAKING & SECURITY: The archive extraction functions now pass 3 security flags (SECURE_NODOTDOT, SECURE_NOABSOLUTEPATHS and SECURE_SYMLINKS) to libarchive by default, unless the current directory is the root. -BREAKING: The ArchiveEntry properties atime, mtime, ctime, birthtime and size now have the value None instead of 0 when they're unset. -BREAKING: The ArchiveEntry.pathname property now attempts to decode bytes using UTF-8. This breaks reading archives that contain file names which look like UTF-8 but aren't, if such a thing exists. Proper support of encodings will probably be added in the next version. -Multiple entries from the same archive can now be kept in memory, however only the current entry's content can be read. -The filetype, linkpath, size, mode, redvmajor, redvminor, uid and gid attributes of an archive entry can now be modified. -The four time properties of archive entries now have setters, so for example entry.set_mtime(0, 0) can be replaced by entry.mtime = 0. -Archive entries have 4 new properties: perm, rdev, uname and gname. -When adding files to an archive, a destination path can now be specified. -The ArchiveRead class now has a bytes_read property. -The ArchiveWrite class now has a bytes_written property. -Python 3.6 is no longer tested. -The documentation has been improved.

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.
