Load https://treeherder.mozilla.org/#/jobs?repo=mozilla-inbound In the top-left corner there is a "tab" for mozilla-inbound, with an info icon. Click on the info icon. Expected: the popup shows the latest mozilla-inbound tree status Actual: it says "Nov 21 Tree closing window https://bugzil.la/1214712" which is a very stale status. treestatus.m.o has much more recent statuses. This seems to affect other trees as well, like m-c, aurora, beta, fx-team, etc.

More direct way to see this: Visit any of these: https://api.pub.build.mozilla.org/treestatus/details/mozilla-aurora https://api.pub.build.mozilla.org/treestatus/details/mozilla-beta https://api.pub.build.mozilla.org/treestatus/details/mozilla-central https://api.pub.build.mozilla.org/treestatus/details/mozilla-inbound https://api.pub.build.mozilla.org/treestatus/details/fx-team All of these show "Nov 21 Tree closing window https://bugzil.la/1214712" under the Open/Approval-Required/etc. status at the top. I tried to fix this on Aurora, as you can see from recent changes at https://api.pub.build.mozilla.org/treestatus/details/mozilla-aurora -- I picked "Change Tree Status" to "Approval Required" (i.e. not changing the status), and tried putting in 1-space-character strings for both "reason" & "message of the day" (to clear the "no change" default value), but it didn't work -- the "Nov 21 Tree closing window" message is still there at the top.

(I'm pretty sure TreeHerder just pulls this data from treestatus, so I don't think this is a treeherder bug -- reclassifying as a treestatus bug.)

That's not the tree status, it's the message of the day, which someone set for that TCW, clobbering every existing MoTD. Treestatus not only doesn't log changes to MoTD so someone could just set them all back to what they were, it doesn't appear to have any way to set them blank, so someone will have to set them all to some non-blank value.

I've set better MotDs for almost all of the trees except for the twigs and the various try branches.

Thanks, KWierso!

I can see this message for try: "Nov 21 Tree closing window https://bugzil.la/1214712"

Same here. ni=kwierso since he fixed this before & hopefully can fix it again (and maybe figure out why it happened again)

Set try's MotD to point to https://wiki.mozilla.org/Build:TryServer#Getting_access_to_the_Try_Server for lack of a better page. Why it happened was because I never set MotDs for twig or try repos back in December, so there was no 'again'.

It was a pleasant five days of having them all fixed, but now they are all "TCW in Progress - sheriff your own builds". Filed bug 1248205 like I should have the last time, and set every tree to "MotDs are a nice thing we can't have."
