Agenda
- Progress report
- Ubuntu Summit (Riga, Latvia) on 3-5 November 2023
- Now it has taken place, the second Ubuntu Summit, this year in Riga in Latvia, and we in
the organization team are already making our first thoughts on the third one...
- Two and a half days of amazing sessions in 5 rooms in parallel. The speakers on this second
Ubuntu Summit were less Canonical employees but more people from the wider community, and not
exactly an Ubuntu Summit but more a Summit about Linux and free software in general.
- See details in November OP News.
- Progress report
- FOSDEM 2024 (Brussels, Belgium) on 3-4 February 2024
- After many years, Till will attend FOSDEM again! The last time Till attended was in the early
2000s when he worked at MandrakeSoft in Paris, having only 90 minutes by train to get there.
From Vienna, Austria Till will have to take a 2-hour flight.
- FOSDEM (Free and Open Source DEveloper's Meeting) is a large conference. It is registration-
free, anyone can just walk in and attend all the talks. There are more than 8000 visitors to
more than 600 sessions in 36 rooms in parallel and ~60 non-commercial exhibition booths.
- There are a few rooms for plenary sessions, main track, and lightning talks with the sessions
selected by the organizers of FOSDEM itself, but most rooms are the so-called devrooms.
59 free software community projects selected by a call for proposals for the devrooms have
received a devroom and are responsible to fill it with sessions, usually via a call for
proposals for presentations. These calls for proposals are currently open and, depending on
the devroom, will close between 1 December 2023 and 8 December 2023.
- Till did 6 submissions, all for sessions which he has already given in similar form on other
conferences, but he would naturally update them where needed.
- See details in November OP News.
- Progress report
- Next year we will have a GSoC again, and this time a very special one, the 20th GSoC!!
- It was announced a few weeks ago.
- Till will participate again with the Linux Foundation and OpenPrinting - and we are already
starting with finding and selecting contributor candidates.
- Potential project ideas are:
* Desktop integration: CPDB support for the print dialogs of Mozilla (Thunderbird/Firefox) and
LibreOffice
* Desktop Integration: Update system-config-printer for the New Architecture of printing
* Desktop Integration: User interfaces for using OAuth2 with printers and scanners
* CPDB backend for IPP infrastructure/cloud printers
* Turn cups-browsed into a Printer Application
- Note that, for general acceptance of CUPS 3.x and of the CUPS Snap, we need to have a desktop
integration for all desktops, not only for GNOME.
- Suggestions for any further project ideas are more than welcome.
- And if you would like to be a GSoC contributor next year, please contact Till directly.
- Progress report
- This year's GSoC came to an end and 4 of our originally 6 GSoC contributors have passed
their final evaluations. They did awesome work which brought us a lot closer to have a smooth
transition to CUPS 3.x and its PPD-less New Architecture. The projects still need a little
work, but the contributors will finish this up in their end-of-year breaks.
- Here are the final results:
* OpenPrinting: CPDB support for application’s print dialogs: Firefox, Chromium, LibreOffice
Contributor: Kushagra Sharma
Mentors: Till Kamppeter, Gaurav Guleria, Shivam Mishra, Rithvik Patibandla, Ira McDonald
- PASSED
* Sand-Boxed Scanner Application Framework
Contributor: Akarshan Kapoor
Mentors: Till Kamppeter, Rishabh Maheshwari, Deepak Patankar, Ira McDonald
- PASSED
* GNOME Control Center: List and handle IPP print services for the New Architecture
Contributor: Mohit Verma
Mentors: Till Kamppeter, Marek Kašík, Zdenek Dohnal, Rithvik Patibandla, Ira McDonald
- PASSED
* Continuous Integration: Test Programs for libcupsfilters, libpappl-retrofit, libppd, CPDB,
CPDB Libs
Contributor: Pratyush Ranjan
Mentors: Till Kamppeter, Deepak Patankar, Zdenek Dohnal, Ira McDonald
- PASSED
* Native Gutenprint Printer Application
Contributor: Gayatri Kapse
Mentors: Till Kamppeter, Rishabh Maheshwari, Zdenek Dohnal, Ira McDonald
- FAILED
* Native Gutenprint Printer Application
Contributor: Yuvraj Aseri
Mentors: Till Kamppeter, Solomon Peachy, Rishabh Maheshwari, Chandresh Soni, Ira McDonald
- FAILED at mid-term evaluation
- Note that Gayatri's original project was "Adding support for the new functionality of IPP
Everywhere 2.x to libcupsfilters and CPDB". This project turned out to not be feasible, so
Till moved her to "Native gutenprint Printer Application", after mid-term, the project where
Yuvraj also failed.
- See details in November OP News.
- Progress report
- Back in mid-2022, when Till joined the organization team of the Ubuntu Summit 2022 in Prague,
he had a 3.5-hour 1:1 video call with the leader of the organization team, Mauro Gaspari,
exchanging ideas of what we could do in this first Ubuntu Summit. And Mauro brought in that
we could do 2-hour interactive workshops where attendees can try out the subject matter on
their own laptops. Till was immediately sold on that and formed the idea to do a workshop
series on how to package applications as Snaps. Mauro liked this idea and Till started to
work on making it reality.
- At the Ubuntu Summit 2022 in Prague, one year ago, it actually took place: One introduction
panel and 5 workshops. All the speakers, including Till, put a lot of effort into designing
the workshops and especially the accompanying examples/exercises. Too much material for
presentation only this one single time...
- See details in November OP News.
- Progress report
- On the snapcraft.io forum thread, where Till asked for help with the problems he talked about
last month in OP October News, a conversation with James Henstridge from Canonical's Desktop
Team started.
- Till explained exactly how CPDB works, how it finds the available backends, and how it
communicates with the backends during the print dialog session in order to actually print a
Job. James also brought up some security concerns and Till told him how we address them.
- Especially we found out that CPDB needs some changes:
* The printFile method of backends needs to pass the job data as stream (file descriptor or
domain socket), not as file specified by a file path.
* The D-Bus methods getActiveJobsCount, getAllJobs, and cancelJob need to be removed from CPDB.
* The file backend of CPDB cannot be used. We should discontinue its development and state that
it is for development and documentation only.
* Filtering of the printer list in the dialog should be completely managed by the frontends,
and not by sending signals to the backends, to allow different filtering on print dialogs
which are open at the same time.
* Add newly appearing backends while the dialog is open.
- Suggestions about how to make CPDB acually work with Snap were not discussed.
- Till has asked Biswadeep to work on these changes and he will do so in December after his
end-of-semester exams.
