Had Monday off as a public holiday.

snapd:

  • Continued to work on polkit interface based on last week’s PR.
  • Created core20 PR #101 (since merged), porting the CI workflow from Travis to a trivial Github Actions one that saves the resulting snap as an artifact to allow for local testing.
  • Created core 20 PR #102, proposing to add libnss-mdns to the base snap in order to enable mDNS host name resolution (i.e. .local host names) for snaps built against that base. The impetus for this was @till-kamppeter needing name resolution for CUPS, but this should also help with e.g. a future version of the Chromium snap built on core20.

Snapcraft:

  • I prepared snapcraft PR #3504 (since merged), which fixes the fonts.conf fragment generated by the desktop extensions to expose fonts from the platform snap.
  • I prepared snapcraft PR #3509 (also merged), which makes use of a snapd 2.50 feature to not expose the host system fontconfig cache to the snap sandbox. This is intended to avoid any remaining problems where incompatible caches are exposed to the snap.
  • I merged @cjp256’s action-build PR #14, and tagged a new release of the snapcore/action-build Github Action. This adds support for a ua-token input parameter in preparation for Ubuntu 16.04 going into ESM.

  • CUPS Snap: When switching to core20 as base Snap I found out that the Core Snap does not do mDNS host name lookups (.local host names, generated by the host itself as part of the ZeroConf/mDNS functionality). These host names are especially important for accessing auto-discovered network devices, like printers, scanners, IoT, admin interfaces of routers, access points, smart home, … Found this snapcraft.io thread which started in September 2019 and also this Launchpad bug originally reported on Chromium and discussed the problem in the snapcraft.io thread. Created a workaround in the CUPS and PostScript Printer Application Snaps. The real fix in the core20 base Snap is povided as PR by @jamesh, he provided a test sample, I tested it, and it works. Thanks, @jamesh and @ogra for all the help. Also added libpaper support.
  • PostScript Printer Application: Also added the workaround for mDNS host name lookup as I did for the CUPS Snap. In addition added checking of the user’s location via locale-related environment variables and based on this use A4 or Letter as default paper size when a new print queue is created. Applied a patch for a PAPPL bug of changes of loaded media are not taken into account when printing.
  • PAPPL: Reported two bugs, one about canceling jobs and shutting down the Printer Application not possible when connection to the printer fails (Issue #163) and another about that if loaded media are changed in the web interface that the change is not applied to print jobs (Issue #164) (currently open and closed issues of PAPPL).
  • cups-filters: Merged pull request with contributions of GSoC 2021 student candidates, especially a severe memory leak of `pdftoraster, removed duplicate PPD file generator, and clean-up on the actually used PPD generator.
  • Google Summer of Code 2021: Organizational work for student selection, inviting mentors, answering mails from mentors of the LF sub-groups, …
  • Bugs.
