Project Discussion Desktop

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 Discourse.
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: Desktop Team Updates - Monday 25th November 2019

  • Zsys:
    • Help jibel with SRU to 19.10 of ZFS support in grub (see jibel’s fix)
      • Released 0.3.3 with the new daemon/server architecture. This one is ready for security review.
    • Refactoring on the main zsys code (ZFS & daemon layer) (living on a separate branch)
      • Added a lot of tests on daemon side, fix some bugs discovered on the way
      • Transaction system adjustements
      • Reconsider what we store on snapshots to ensure that we are not impacted by later changes on system
  • Misc:
    • Update default golang to 1.13 on focal (still need golang 1.13 to be promoted in main, blocked on foundation team to have a team subscription)
    • Compliance training support
    • Some HR stuff

  • cups-filters: Released version 1.25.13, a bug fix release mainly to solve problems of cups-browsed, for compatibility problems with some printers, and also memory leaks, and crashes. Also updated the PPD generator to catch up with the one of CUPS. Prefer Apple Raster instead of PWG Raster as some printers have bugs in their PWG Raster implementation.
  • Snap-only CUPS in 20.04: Further investigations on SANE and its utilities for how to create a Scanner Application framework, for snapping multi-function device drivers like HPLIP
  • Driverless Printing: Investigations of printer incompatibilities, especially printers broken on “media-col-database” IPP attribute, Apple Raster incompatibility, and an oddity with duplex.
  • Hardware: Upgraded SSD on my laptop from 512G to 1T, VMs, snapping, … need space.
  • Bugs.

Last week was a short week (only monday and tuesday).

Highlights:

Plan for W49:

  • gnome-3-34 extension: Rewrite _utils.py to 1) fix the way the build-environment sections are merged and 2) rather use the extension-defined yaml as a base to then apply the user-defined yaml data to (right now it’s the other way around so the extension data overwrites the user defined data). Additional info is available in #1853040
  • cherrytree: take a deeper look at snap theming issue. the snap’d version looks different from the .deb version for some unknown reason. cherrytree snapcraft.yaml

  • Some performance testing in regard to using layouts in a snap, there is a significant cost at startup.
  • Rebased the drawing snap packaging branch on their stable branch rather than master, upstream didn’t want master published to stable. Stable is now the latest in the 0.4 series
  • snap-store: Continued working on enabling everything needed for packagekit and appstream.
  • SRU testing for fwupd
