Logging is broken on Windows
3a24eacb (!3321 (merged)) seems to be the culprit.
Last scheduled master pipeline for which Windows (mostly) worked:
https://gitlab.isc.org/isc-projects/bind9/pipelines/38307
- https://gitlab.isc.org/isc-projects/bind9/-/jobs/802733
- https://gitlab.isc.org/isc-projects/bind9/-/jobs/802734
First scheduled master pipeline for which Windows is broken:
https://gitlab.isc.org/isc-projects/bind9/pipelines/38401
- https://gitlab.isc.org/isc-projects/bind9/-/jobs/804958
- https://gitlab.isc.org/isc-projects/bind9/-/jobs/804959
I narrowed it down to 3a24eacb by testing the merge requests merged between these two scheduled pipelines.
