Your commit was 5 hours after Josh's. I wasn't looking at the buildbot when
your commit came in, but it's certainly possible that the "portbuilder"
builders were idle, and if you had limited your waterfall to just the
"portbuilder" tag it may have appeared that everything was idle. "portbuilders"
don't get triggered until after their parent "portwatcher" has finished
enumerating which ports need to be built and after the "mirror" task for those
ports finishes. Enumerating hundreds of ports takes several minutes, while
mirroring hundreds of ports can take hours. For example, the mirroring task
triggered by the macOS 11 Apple Silicon portwatcher took almost 4 hours:
https://build.macports.org/builders/jobs-mirror/builds/236888
We run the mirroring task again for each portwatcher, i.e. for each build
platform. This is inefficient and we want to improve it but we put it off until
after we update to buildbot 2. See https://trac.macports.org/ticket/59286
We do maintain a cache of what has already been mirrored, so the subsequent
jobs are quicker. The mirroring task triggered by the macOS 10.15 portwatcher
took "only" 75 minutes since a lot of work could be skipped since it had
already been done by the previous task:
