Snapd

  • One PR, multiple outcomes snapcore/snapd 12179:

  • cups-filters: Code clean-up work for the cups-filters 2.x release continuing, now did the clean-up of libppd and of all the test suite programs of the different libraries. Also moved the test suite programs into the correct directories. Moved the filter functions for calling external filter executables back from libppd to libcupsfilters (now with the name cfFilterExternal() and ppdFilterExternalCUPS() being a wrapper), as it is also useful in native printer applications, as it allows using filters written in non-C languages or proprietary, closed-source filters. Also added support for System V interface scripts to the function (they are similar to CUPS filters but take input from named file, not from stdin). This was inpired by the work of GSoC contributor Chandresh Soni on the Braille Printer Application where he needs to embed shell-script filters into the native (not using PPD files) Printer Application.
  • GNOME Control Center “Printers” module: @elioqoshi suggested to me to file an internal issue report about the UI/UX design needs for the new functionality, so that the work gets added to the Ubuntu 23.04 development cycle. So I posted the report with links to all the work and also write-ups about the motivation. @elioqoshi will not be on the Engineering Sprint in Prague, unfortunately.
  • Retro-fitting Printer Applications/pappl-retrofit/PAPPL: Updated pappl-retrofit to work with Michael Sweet’s fix for string-type user-settable options (passwords, fax numbers, …), so that the Printer Application Snaps do not need patches on PAPPL and pappl-retrofit any more. Also updated the 4 retro-fitting Printer Applications appropriately. In addition did updates on the Snaps for the most recent API changes in cups-filters (merged libfontembed, cfFilterExternal() in libcupsfilters, see above) and updated them all to Ghostscript 10.00.0, which has especially a faster PDF renderer and latest support functionality for PPD-less printing.
  • Ubuntu Summit 2022: @ilvipero got COVID and Sam Adams was on vacation so I tried to help somewhat more on the organization of the Summit. Reviewed more talks submissions, identified submissions which we cannot reject, listed workshop and talk submissions about Snap and Flutter and listed all the dependencies (especially workshop B needs the knowledge tought in workshop A, talk C is a great teaser/preparation for workshop B), taken the lead on half of the weekly meeting, found out about the equioment in the rooms and how to run OpenPrinting BoFs with remote participants, a gaming night where attendees can bring their tinkering work, answered questions of submitters, and nagged the team doing the scheduling to fulfill all the dependencies …
  • Google Summer of Code 2022: Continued mentoring our remaining 3 great contributors. Usual Telegram chats, video meetings, Pull Requests. Also helped the others with the upstream integration of their work. Evaluated all the first 4 as having passed the program. Now, after the deadline for the mentor’s evaluations has passed, the contributor’s evaluations got revealed and all the 4 praised my work as mentor a lot.
  • Bugs.

  • snap-store bug: @SergioCostas and I did some further testing and verification of the bug. There are 2 issues here: autostart line needed in snap-store app (fixed here), and notifications are not being populated. For the latter, it is worth noting that the snap-store does not use the same gnome-software mechanism to create notifications, but rather update-notifier and update-notifier may not be aware of firmware updates - more investigation on this is needed.
  • Setup next indaba. The topic is Kinetic Kudu! Join myself, @kenvandine , @local-optimum , @kewisch , @adamszopa , and @rs2009 - Rudra Saraswat from the new Unity Flavor!
  • Flutter snap workshop prep: Created base flutter app and tried to snap it. Talked with Ken and Sergio about plan to provide flutter snap plugin for core22 snaps. I will look at adding this plugin after the release, while people are at the product sprint.
  • WRG (Womens Resource Group): got access to sales force and can make POs for the various WRG initiatives
  • Ubuntu Summit: Thanks @kewisch for helping me publish a new blog post trying to convince people to attend the event in person :slight_smile: Also published another newsletter
  • Did a new release of blueprint-compiler 0.4.0-1. Turns out the s390x build was broken so we did another release 0.4.0-2. Thanks to @jbicha for the mentorship and upload!
