Desktop Team Update - Monday 19th August 2019

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 Update - Monday 12th August 2019
Next week’s notes are here: Desktop Team Update - Monday 26th August 2019

(week was shorter, one national holiday)

  • Eoan work
    • desktop updates, duplicity, alsa-lib/plugins/utils, geoclue, libnotify, gtksourceview4, cogl, graphene, gucharmap, cheese, libgdata, gdk-pixbuf
    • Debian merges & syncs, tdb, gtk+3.0, glib2.0, libabw
    • worked on preparing a new poppler update/transition (they changed soname as usual)
    • helped on the e-d-s transition (syncevolution, abiword, evolution-indicator)
    • helped with the gnome-desktop new soname/rdepends rebuilds
    • fixed a gnome-screensaver patch breaking build, updated the apport hook to use python3 and fix a merge error from a previous upload
  • Almost all of the work this week was for GNOME 3.33. Various updates for API changes, rebuilds and other issues. I coordinated with @3v1n0 and others to get some things updated (e.g. dash to dock, the Yaru theme, … - thanks for working on that.)
  • This update brings systemd --user support (using systemd to start the GNOME session), which I worked on a few months ago and recently Benjamin Berg has been polishing up. I found a bug in the implentation that landed and worked on fixing that, discussing with the upstream folks.
  • …and also, on the same systemd topic, I’ve been preparing some content for our GUADEC talk; see you there if you’re going.

snapd user session agent:

  • PR #7197, adding exit on idle behaviour to the agent plus some SO_PEERCRED security checks is still waiting, probably for the snapd 2.41 release process to complete.
  • PR #7238, adding a control API for the user instance of systemd received a preliminary review.
  • I’ve been working on some client library code to talk to all available session agents. I am structuring things so that there is a single client that talks to all available session agents in parallel. All APIs take a context.Context parameter allowing strict timeouts to be placed on responses (important given that this will be privileged code talking to unprivileged code).

snapd icon theme support:

  • PR #6767 received security sign off after adding some sanity checks for the icons specified by path (i.e. the existing non-icon theme mode of operation that all desktop snaps use). The PR has been pushed off to the 2.42 milestone, so I expect it to get merged soon after 2.41 is released.

Control of desktop file IDs for snaps:
