  • CUPS Snap: Waiting for @ijohnson’s pull request on snapd for the cups printing interface to get merged by the snapd team (especially a review by @jamesh is missing). Talked with @ijohnson (who is currently already EOYing now) and he will do the final steps (fix bug of needing to re-connect “cups” interface after snapd update) in the beginning of January.
  • cups-filters: Continued working on a bug discovered by switching the implicitclass backend of cups-browsed from calling CUPS filters as external executables to use filter functions. The mysterious thing is that if one filter function is chained with a backend by a pipe, the data does not make it through the pipe to the backend. With two filter functions and the backend at the end chained by pipes the data makes it all the way through to the backend and so to the final destination. The filter function called right before the backend is the same in both cases, and the first filter function in the second case is neutral (input data same as output data), so very strange that the pipe to the backend fails in the first case. Update: Finally found a fix (problem was that stdin got closed prematurely in the backend sub-process).
  • Google Summer of Code 2022: Started to assign issues of OpenPrinting GitHub projects to applicants.
  • OpenPrinting: Sent e-mails to some voluntary/hobby contributors trying to motivate them to do some work on their projects during the EOY break.
  • Bugs.
