Hi everyone, below you will find the updates from the Desktop team from the last week.

If you’re interested in discussing a topic please start a thread in the Desktop area of the Community Hub (this site).
We also have our weekly meeting on IRC. We meet on Tuesday at 13:30 UTC in #ubuntu-desktop on Freenode. There will be an “Any Other Business” section at the end where you are welcome to raise topics. These topics might be discussed during the meeting, or afterwards depending on the time, depth of conversation, topic and so on.

Last week’s notes are here: Monday 24th June
Next week’s notes are here: Monday 8th July

  • ZFS:
    • Debugged and fixed https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1834095 by porting the awk part of
      10_linux_zfs from awk to shell and fixed other mawk incompatibilities.
    • Added more tests and mocks (tests are now running with gawk and mawk)
    • Convert to new go-libzfs version and remove various hacks we had.
    • Inspect systemd generation and zedlets. See how to integrate zsys into this. Still more work needed (but once 0.8 is in distro)
    • Continue hacking on base zfs layer for zsys support. TestSnapshot is now complete
    • Refactoring as well on zsys for prepraring Clone() support
    • More test infra on zsys, ensuring that the incoming Clone() will report the correct properties source.
    • Archived and reflect on June work and plan July work: https://trello.com/c/6UmbgX8f/185-zfs-july-work
  • Misc:
    • Review some rebuild SRU for graphivz (for ubuntu core team)

snapd interfaces for snap-store:

  • In order to extend snap-store to manage traditional .deb packages, we need to expose the host system package manager to the snap sandbox.
  • The first thought was to use aptdaemon and libapt-pkg, but this doesn’t look workable at least in the short term: the library and daemon are tightly coupled, so there is no guarantee that the library inside the snap will be able to use the host system’s daemon or package caches. So at least in the short term, the plan is to continue using PackageKit.
  • I’ve been working on two new snapd interfaces to support this: appstream-metadata providing access to information about installed and available packages on the host system, and packagekit-control providing access to the PackageKit D-Bus service. By keeping these separate, the AppStream interface could be paired up with a PackageKit successor interface.
  • PR #7042 implementing appstream-metadata is essentially complete and waiting for review. Robert took a quick look over to make sure it was sane, but it needs a real review.
  • PR #7054 implementing packagekit-control has unit tests but needs a spread test. My current plan is to snap a copy of the pkcon command line tool and use that to verify that we can talk to the host system PackageKit.

Other snapd PRs:

  • I’m still working to get my other snapd PRs (icon themes, user session agent) landed. I’m in communication with the snapd developers to push them forward.

  • network-manager: Further investigations of the autopkgtest script nm.py as sometimes the tests failed, typically due to a timeout on the emulated Wifi AP not coming up. Submitted a debuggability improvement to avoid that the script hangs and autopkgtest finally kills it after 2 hours without a chance to know where it got stuck.
  • network-manager: Investigated Bionic SRU regression and asked on upstream mailing list whether there is a possible fix, no answer yet. Also asked on #nm Freenode channel but no one seems to be listening there.
  • Google Summer of Code 2019: First month’s evaluations done. All the 11 students (including the 5 for OpenPrinting) have passed and go on working for the second month. The OpenPrinting students also were very content with their mentors. Continued guiding the students on the Printer Application snap framework and on the Common Print Dialog Backends integration on the GTK print dialog.
