Desktop Team Updates - Monday 25th January 2021

[vanvugt]

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 18th January 2021

[vanvugt]

• Most of the week spent investigating the Hyper-V Xrdp issue. No fix, but some interesting findings documented.
• Proposed a patch for focal to address the gnome-shell crash in st_bin_destroy. It might even solve some leaks relating to desktop icons refreshing, in case anyone still experiences those.
• PulseAudio branch repairs to sync with the archive contents.
• Unblocked the 3.38.2 SRUs for groovy, which are now released (1, 2).
• Lots of daily bug triage in Launchpad and upstreams.
• Backlog tracking.

[laney]

• Attended planning / review sprint for the hirsute cycle, lots of internal meetings
• Moved forward a bit on new autopkgtest rollout, just made one small request of IS after which I can try deploying it for production I think (still need to test github requests though).
• Discovered apport was failing to fail on autopkgtest too, fixed that.
• SRU verification for glib2.0, followed up with bug fix for libxmlb (+ upstream + Debian) for a flaky test which that showed up.
• Some ubiquity reviews / testing / uploads.
• Talked with appstream-generator upstream ximion a bit about a new release after some regressions were fixed, but the snap build fails now.

[seb128]

• joined Canonical mid cycle review meetings
• desktop updates and Debian merges
• reviewed our alsa changes and got the lib and ucm sources synced again from Debian
• wrote the abseil MIR report details, new depends of mozc
• wrote the libdeflate MIR report, new depends of libtiff
• got our poppler delta merged and uploaded to Debian
• got my component mismatch change to add the source in the email merged, thanks Laney!
• updated pulseaudio to the current stable version
• verified some SRU
• debugged a GTK translations import issue reported by the Catalan team, which was again due to translation sharing being turned on for the source on launchpad
• reviewed the setting value for other component, for some reason it was enabled for most that breaks imports :-/
• reviewed and sponsored a fix from Gunnar for s390x symbols being different from Debian

[till-kamppeter]

• PostScript Printer Application: Continued work on the web interface page for adding PPD files: list the PPDs already added and allow removing them, refresh button to update the driver list after manually addin PPD files. Also check PPD option whether they provide PostScript or PJL code to have actually effect on print jobs, both on PPD upload and on setting up the driver data structure. With this the PostScript Printer Application is complete as far as possible with current PAPPL. We are still waiting for internationalization/human-readable vendor option support, ink level readout support, and printer auto setup.
• Retro-fit Printer Application: I will soon move the functions of the PostScript Printer Application into a library (libpapplretrofit ?) to re-use them for other PPD-filter-retro-fitting Printer Applications for Foomatic, Ghostscript, foo2zjs, SpliX, …
• PAPPL: Reported issues about support for string/text-style vendor options, a crash when removing a printer and after that create a new printer with the name of the removed one where the latter got solved, investigations on the PostScript Printer Application only loading the first 4096 bytes of its state file (PAPPL issues: open, closed).
• system-config-printer: Updated hirsute package to 1.5.15 fixing a nasty bug of s-c-p hanging when changing the driver of an existing queue and merging all changes from Debian.
• CUPS Snap: Still waiting for @jamesh’s API extension of snapd to pass Canonical’s security team review so that the CUPS Snap makes it into the Snap Store. Changes have passed the security team.
• sane-airscan: Waiting for the MIR to get reviewed by the security team.
• Google Summer of Code 2021: Mentored several candidates on working on cups-filters and CUPS GitHub issues as part of the selection process.
• Bugs.
