Current Dev Position: YP 3.1 M2
Next Deadline: YP 3.1 M2 build date 1/20/2020

Next Team Meetings:

Tip of the Week:

  • ‘You can quickly test a change to a recipe on a target by rebuilding it alone, then rsyncing pieces of WORKDIR/image/ or WORKDIR/packages-split/PACKAGENAME/ rather than rebuilding the image (bit of a hack but effective).
  • (anyone with tips they’d like to see here, please send to Stephen or Richard)

Key Status/Updates:

  • YP 3.1 M2 will build shortly, the only remaining blocking issue is the buildtools-extended-tarball fixes which should happen today.
  • Python 2 has been finally removed from OE-Core. This was long scheduled and whilst its causing problems for other layers, we really need to resolve those issues now rather than later in the release cycle so it is the right time to finally do this.
  • Patch merging continues to be making good progress and staying roughly up to date.

Yocto Project Weekly Status January 14, 2020

Current Dev Position: YP 3.1 M2
Next Deadline: YP 3.1 M2 build date 1/20/2020

Next Team Meetings:

Tip of the Week:

  • ‘oe-pkgdata-browser’ is a new handy small helper UI added by Ross to visualise the pkgdata held within a build.
  • (anyone with tips they’d like to see here, please send to Stephen or Richard)

Key Status/Updates:

  • YP 3.1 M2 is due to be built next week.
  • Patch merging is roughly on track however there are a number of failures identified with key patches (glibc has a prelink issue on mips, python 3.8 upgrade blocked on uid issue, gstreamer meson transition blocked on nodistro failure). Most of these issues are making progress over time.
  • The more worrying aspect is that there are a number of recurring/intermittent failures in the automated testing, mostly from selftest and testimage.
  • Looking at the build history, “full” images have built cleanly only once in the past month (3 times in the last two months), which is a pretty shocking statistic which summarises the challenges we face there. Most of these are being procrastinated on by the bug owners since we can’t reproduce them at will. We really need help working on these kinds of issues.
  • We have changed the sstate mirrors to be per release, simply to lower the numbers of files in any given sstate directory.
  • The triage team is worried about attendance at triage meetings and the project is finding it hard to find people to help fix bugs. If anyone is willing to work on bugs, assistance would be greatly appreciated.

Proposed YP 3.1 Milestone Dates

  • YP 3.1 M2 build date 1/20/2020
  • YP 3.1 M2 release date 1/31/2020
  • YP 3.1 M3 build date 2/24/2020
  • YP 3.1 M3 release date 3/6/2020
  • YP 3.1 M4 build date 3/30/2020
  • YP 3.1 M4 release date 4/24/2020

Planned upcoming dot releases:

  • YP 2.7.3 build date 2/10/2020
  • YP 2.7.3 release date 2/21/2020
  • YP 3.0.2 build date 2/3/2020

Yocto Project Weekly Status January 7, 2020

Current Dev Position: YP 3.1 M2
Next Deadline: YP 3.1 M2 build date 1/20/2020

Next Team Meetings:

Key Status/Updates:

  • YP 3.1 M1 was released.
  • Over the last two weeks there were a number of significant fixes for hash equivalence which should resolve some of the long standing bugs reported here. Some of these fixes may require further architectural tweaks to the codebase but those are cleanups which can happen in due course now the root causes are identified.
  • There are performance issues that remain in hashequivlence but these will be looked at only once the correctness issues and intermittent test failures are addressed.
  • There are some puzzling selftest failures that remain, in particular a locked signatures one which seems to be caused through bad interaction with the hash equivalence code but is intermittent and does not make sense.
  • The patch queue for master should be roughly up to date which some key changes such as the gettext upgrade having merged recently. Some pending changes like the glibc upgrade look problematic.
  • A key functionality change has merged this week where the layout of the sstate directory has changed. This was done to try and improve performance and handle some performance issues where the previous code simply wasn’t scaling. There is no user visible impact but it does mean new sstate will be generated into a new layout and the older sstate will be ignored. The sstate filename length issues should also be addressed by this patchset.
  • Whilst the SWAT process is disbanded, the effect of this is that Richard now has to file the bugs personally. This distracts from other things that could be worked on.
  • The triage team is worried about attendance at triage meetings and the project is finding it hard to find people to help fix bugs. If anyone is willing to work on bugs, assistance would be greatly appreciated.
  • The TSC is working on LTS plans, productive discussions have been had and a new policy on handling this and stable releases should be available in the coming weeks.
  • We are continuing to collect ideas for YP 3.1 in this document: https://docs.google.com/document/d/1UKZIGe88-eq3-pOPtkAvFAegbQDzhy_f4ye64yjnABc/edit?usp=sharing
