Aha, ok, then it makes sense I didn't find it immediately.

BTW. For people who didn't see it yet, the builder frontpage
https://builder.sourceware.org/ contains little bunsen burner icons
next to the project or builder which are links to the recorded
testresults for that project or a particular builder so you can easily
dig into the results or compare results between bulds.

Separation of processes/permissions is important. You can also do that
in the buildbot model, but it does take a bit more configuration than
just installing a cronjob. You could have a separate worker just for
the ingestion process. Then when the buildbot scheduler sees a change
in the bundendb.git it signals that worker to do a ingestion build
under its own process. Or you can use a Dependent or Triggerable
Scheduler to run a build against a different worker after a bunsen
upload step succeeds.
