  • CUPS Snap: Waiting for my request for the CUPS Snap to auto-connect to the system’s cups-control interface be approved by the Snap Store team. @alexmurray could you check whether there is all OK now? It is very important to get this auto-connection working as we have already > 60000 installations of the CUPS Snap as dependency on application Snaps plugging the new cups interface.
  • cups-filters: Continued with restructuring towards the cups-filters 2.x release, continuing replacing direct PPD file access in the filter functions by converting PPD options and attributes to IPP printer attributes and control options in the ppdFilterLoadPPD() function (which calls ppdLoadAttributes()) in libppd. Also made cfFilterRasterToPWG() and cfFilterPWGToRaster() free of PPD file support and created appropriate ppFilter...() wrapper filter functions for them. Tested handling of media size, margins, and page geometry and found some issues. Did several improvements on the cfGetPageDimensions() and cfGenerateSizes() functions to solve the problems, especially also added support for page size variants in PPD files (A4, A4.Borderless, A4.Duplex, … differences in margins, sometimes even a bit in size), matching of custom page sizes, and pages rotated by 90 degrees.
  • Native Gutenprint Printer Application: Another video meeting with the GSoC contributor and Solomon Peachy (Gutenprint upstream developer) to talk about how the rastertogutenprint CUPS works and how to do the job processing in the Printer Application.
  • "Printers" module in GNOME Control Center: Started discussion about how to implement access to the web administration interface of an IPP printer/service, especially also whether to open it in GNOME’s own Window (or embedded) like the Captive Portals for Wi-Fi login or via the user’s web browser. We opted for the latter. Upstream Marek Kasik opened another feature request.
  • Linux Plumbers Conference 2022 in Dublin: Further organizational work for the OpenPrinting micro-conference, created proposals for all the planned topics, helped a speaker to get his proposal correctly posted.
  • GUADEC 2022 in Guadalajara, Mexico: Had some chat with one of the organizers of the mini-GUADEC in Berlin, a conference for whom is not able or does not want to travel to Mexico, with all the GUADEC talks being live-transmitted for public viewing and hackfest. Suggested him to host the Linux App Summit 2023 with his group. Thanks @jbicha for giving me the hint about this event and thanks @hellsworth to give a lightning talk about how to apply as LAS host on GUADEC.
  • Google Summer of Code 2022: The 8 contributors started coding and I had several meetings and chats with them to discuss their project work, answer their questions, help them get started, … before my next week’s vacation.
  • Bugs.

  • GNOME Shell 42.2 landed in jammy-updates this week.
  • Updated rhythmbox in Debian and Ubuntu to 3.4.6. This was the first rhythmbox release in 2 years. Along with the switch to meson are new build tests. I temporarily skipped a test that fails only on arm64.
  • Submitted a merge proposal to allow running rhythmbox’s build tests more easily without having rhythmbox’s gsettings schemas pre-installed
  • Completed the tesseract & x264 transitions for Ubuntu 22.10
  • Forwarded our spice packaging diff to Debian to allow Ubuntu to sync future Debian packaging updates, if my merge proposals are accepted.
  • Packaged glibmm2.68 which are the glib bindings for C++ GTK4.
  • I did some further investigation of gnome-tour as a potential .deb package. gnome-tour is a minimal rust app. I wasn’t able to get the 41 version to build unvendored because of a mismatch in the libhandy dependency available in Debian. The 42 version is blocked because the rust libadwaita bindings aren’t in Debian yet. I think we’ll be able to get those bindings in to Debian this year which should allow gnome-tour to be packaged and the new loupe image viewer app. This was my first time working with devendoring a Rust app and I learned a bit more about how the Debian Rust team packages libraries.
