Enterprise Desktop / AD

  • paired with didrocks to create a separate Debian binary package for Windows-specific adsys tools (Windows daemon and policies)
  • fixed some race conditions in the integration tests (1 more to go for Linux, a lot more to go for Windows)
  • updated adsys CI to also run adwatchd tests on Linux (including integration tests), and merge coverage from both projects before sending report to Coveralls
  • various adsys repo adjustments to facilitate git clone-ing on Windows - renamed some golden tests to avoid illegal path characters (e.g. +:<>)
  • prepared Windows CI in GitHub Actions to run package and integration tests, and also build the installer .exe and attach it as an artifact to the workflow run
  • updated GitHub Actions to automatically draft a release when a tag is pushed, and attach the installer .exe to it

WSL

  • CUPS Snap: When putting together the June News Post on OpenPrinting I got note of the installed base of the CUPS Snap sky-rocketing from ~4200 to ~42000 and the reason is good news: The first two applications in the Snap Store which switched to the cups interface: FreeCAD and onlyoffice-desktopeditors! Congratulations to their developers and thanks to @roadmr of the Snap Store Team for providing me this information. But to make everything perfectly working, I have posted a request for the CUPS Snap to auto-connect to the system’s cups-control interface. @alexmurray could you check whether there is all OK now?
  • 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. Completed treatment of backside orientation, rendering intent, color management/colord, “PageRegion” option of PPD files, fixed a bug in cfRasterMatchIPPSize() to have output compatible to ppdRasterMatchPPDSize(), fixed crash bugs in Raster header generation for PWG Raster and PCLm, and in determination of the color space, and finally got the cfFilterPDFToRaster() (Poppler-based rasterizer) free of PPD file dependencies. Now treating the remaining filter functions is much easier, as they use merely the same information from the PPD files.
  • Braille Printer Application: Had a video meeting with the GSoC contributor and the author of the current Braille embosser driver in cups-filters, Samuel Thibault (who will also be the mentor) for planning the work. Learned a lot about Braille and Braille printing by that.
  • Scanning support for PAPPL: Had a meeting with the two GSoC contributors, explained what is all needed and re-distributed the work between the two as originally one was supposed to do IPP Scan support and the other eSCL support and now we decided to drop IPP Scan as no one actually uses it.
  • GUADEC 2022 in Guadalajara, Mexico: Booked everything and continued the planning, especially about the Canonical (developer) booth (thanks @hellsworth for the great organization work, and thanks @kenvandine about telling how the booths work). Posted a teaser about Canonical’s GUADEC participation in the June OpenPrinting News.
  • Google Summer of Code 2022: Coding period has started yesterday. For the contributors also the end-semester exams at their colleges ended. So started mentoring and had several meetings and chats (see also above). Also listed all the 8 projects and reported about their kick-off and initial design decisions in the June OpenPrinting News.
  • OpenPrinting: Monthly video meeting and June News Post. Special features this month are: Canonical on GUADEC, All GSoC 2022 projects, first apps use cups interface
  • Bugs.

  • Working with others on an alias conflict with the pipewire-session-manager systemd user services shipped by wireplumber and pipewire-media-session.
