Comment 1

[Timothy Nikkel (:tnikkel)]

Is this just because we purged autoland builds that old?

Comment 2

[Henrik Skupin [:whimboo][⌚️UTC+1]]

There is at least one more nightly build which could have been checked. I had to do that manually.

But otherwise the merge wasn't done from autoland but inbound. So maybe that's the problem now.

Comment 3

[Ian Moody [:Kwan] (UTC+1)]

This isn't due to missing nightlies, it's finished with nightlies and successfully switched to taskcluster for m-c integration builds, which is returning no builds for those commits. Normally taskcluster integration builds last for a year, so [2019-11-06, 2019-11-07] is coming up on them expiring anyway, but it so happens that the taskcluster migration was on 9th November 2019, so anything before then was already deleted when the old cluster was decommissioned in July.

(In reply to Henrik Skupin (:whimboo) [⌚️UTC+2] from comment #2)

There is at least one more nightly build which could have been checked. I had to do that manually.

Support for the two-nightlies per day model has never been added to mozregression, so it only treats each day as having a single build.
