Yocto 1.2, "denzil" was released on April 30, 2012. Work is now happening in parallel for 1.3 as well as the 1.2.1 point-release. This page describes some of the workflow/guidelines of what will go into the 1.2.1 release.

Scott Garman is the maintainer of the 1.2.1 release. His email is scott.a.garman@intel.com and he can be found on Freenode IRC as zenlinux in the #yocto, #poky, and #oe channels.

Git Branches

Scott is maintaining two git branches, one based on oe-core, and one based on poky:

http://git.openembedded.org/openembedded-core-contrib/log/?h=sgarman/denzil-next

http://git.yoctoproject.org/cgit/cgit.cgi/poky-contrib/log/?h=sgarman/denzil-next

Focus and Scope

The primary focus for getting patches into 1.2.1 is bugfixing, security updates, and making sure that recently released Ubuntu, Fedora, and OpenSUSE distros work with this release. All other kinds of patches (e.g, performance improvements) will have a very high bar to reach for them to be accepted (i.e, it will have to be very clear they pose little risk to introducing more bugs or stability issues). Anything that breaks APIs or compatibility is off the table.

Please mention in your pull requests if you wish to have your commits included in the 1.2.1 release.

The intention is to include bugfixes for these bugs in the eventual release of 1.2.1:

https://bugzilla.yoctoproject.org/buglist.cgi?query_format=advanced&list_id=4572&bug_status=NEW&bug_status=ACCEPTED&bug_status=REOPENED&bug_status=NEEDINFO&bug_status=WaitForUpstream&bug_status=RESOLVED&bug_status=VERIFIED&bug_status=CLOSED&target_milestone=1.2.1

This list is not set in stone and may change at any time.

Workflow

Scott will monitor the oe-core and poky/yocto mailing lists for commits that are relevant for the 1.2.1 release (again, mentioning in a pull request that you want the pull's contents in 1.2.1 makes things much easier for him). After the commits get merged into oe-core master and/or poky master, Scott will add these commits to an sgarman/denzil-next-testing branch to run some basic build tests on. If the build tests pass, Scott will merge the commits to the corresponding sgarman/denzil-next branch(es).

Please be aware that sgarman/denzil-next and especially sgarman/denzil-next-testing can be rebased at any time.

Testing

Building our reference images (core-image-minimal and core-image-sato) for all five of our QEMU architectures is the most basic testing that needs to be done on an ongoing basis (ideally, nightly) with the denzil-next branches. Additionally, the following use cases also need to be exercised on a regular basis (i.e, weekly):

  • non-GPLv3 builds
  • poky-tiny distro builds
  • ADT installer builds
  • meta-qt3

Schedule

The goal is for a release candidate to be ready for 1.2.1 approximately 6-8 weeks after the release of 1.2.

1.2.1 Bug Status Summary

Note that all of these fixes are also applied to the poky-based sgarman/denzil-next branch.
