Desktop Team Updates - Monday 27th January 2020

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: https://discourse.ubuntu.com/t/desktop-team-updates-monday-20th-january-2020/14025

  • CUPS in a Snap: Many more fixes and improvements (studying other snaps, like lxd):
    • Struggeled with DNS lookup not working for .local (Bug 1838038, should be made an rls bug)
    • Added AirPrint server functionality to CUPS
    • Added system-files interface plug to make password authentication work
    • Added shutdown and reload scripts for CUPS and for cups-browsed (now I have a clean shutdown, first cups-browsed then cups)
    • Moved config files to the $SNAP_COMMON dir, PID files to $SNAP_DATA/var/run
    • Do not re-create the config files on every restart or update
    • Updated cups-filters to version 1.27.0 (worked on cups-browsed here to reliably work with CUPS on an alternative port, only connecting via domain socket).
  • cups-filters: Released upstream version 1.27.0: In this release cups-browsed does not need to know the port number of the CUPS daemon it is attached to any more when it connects via domain socket and many additional filters support zero-page jobs now (Issue #117).
  • IPP-over-USB: Further tests on the ippusbxd replacement ipp-usb
  • Focal: IRC Meeting with @kenvandine about the transition of the printing/scanning support into snaps. For Focal we should only convert the drivers and introduce the CUPS snap in the very beginning of the 20.10 cycle so that it gets well tested.
  • Google Summer of Code 2020: Continued to let student candidates on assignments (like cups-filters bugs) to evaluate them for this year’s GSoC).
  • Bugs.

  • PR #7456 (client library for user session agent) has been reviewed. It still needs to be merged.
  • I’ve been reworking PR #5822 (user daemons support) to work with latest trunk and add support restarting user daemons. I’ve still got a bit to go before it is ready for a re-review.

Fixes for “nakedret” static analysis tool

  • Last week, CI started failing for all snapd pull requests. I helped track down the cause, which was an upstream update to a static analysis tool.
  • The update was intended to fix some false negatives in the tool’s reporting. Unfortunately it also introduced a lot of false positives.
  • I helped track down what was happening (nakedret issue #11), and put together the fix (nakedret PR #12). The changes were accepted upstream, and snapd CI was fixed.
