Got this failing constantly on the same machine (mm-win-7-32-1.qa.scl3.mozilla.com) for Firefox 49 Beta 2 ondemand updates on beta-cdntest - see the following job and the next three: https://treeherder.mozilla.org/#/jobs?repo=mozilla-beta&revision=b1bdd0f3482a&group_state=expanded&filter-tier=3&filter-searchStr=Fxup-beta-cdntest(&selectedJob=1438838

This failure mainly occurs on Windows XP machines. The slave nodes we currently have in mozmill-ci had all a Java update prompt open. Looks like the update checks somehow have been turned on again. I disabled the update checker completely now by removing it from the autostart. Lets see if that makes a difference. If not I will re-check this bug again.

So this problem seems to have started on May 22nd: https://brasstacks.mozilla.com/orangefactor/?display=Bug&bugid=1274943&startday=2016-05-01&endday=2016-05-29&tree=all We actually fail to switch to the old UpdateWizardDialog: > dialog = self.windows.switch_to(lambda win: type(win) is UpdateWizardDialog) It means that the build we are running at this time is the one from May 21st due to Fxup-nightly(en-US-1). So a change between May 20th and 21st should have caused this problem.

Those are all the changesets between May 20th and 21st: https://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=c67dc1f9fab86d4f2cf3224307809c44fe3ce820&tochange=f1f2644d34440fe38c098e323bf570e09197e51a There is nothing in that list which indicates this failure, which was really only mozilla-central related at this time.

Nowadays the logs are actually showing a JS exception: 05:54:25 INFO - ************************* 05:54:25 INFO - A coding exception was thrown in a Promise resolution callback. 05:54:25 INFO - See https://developer.mozilla.org/Mozilla/JavaScript_code_modules/Promise.jsm/Promise 05:54:25 INFO - Full message: TypeError: win is null 05:54:25 INFO - Full stack: onSuccess@resource://app/components/nsBrowserGlue.js:758:17 05:54:25 INFO - Handler.prototype.process@resource://gre/modules/Promise.jsm -> resource://gre/modules/Promise-backend.js:937:23 05:54:25 INFO - this.PromiseWalker.walkerLoop@resource://gre/modules/Promise.jsm -> resource://gre/modules/Promise-backend.js:816:7 05:54:25 INFO - Promise*this.PromiseWalker.scheduleWalkerLoop@resource://gre/modules/Promise.jsm -> resource://gre/modules/Promise-backend.js:747:11 05:54:25 INFO - this.PromiseWalker.schedulePromise@resource://gre/modules/Promise.jsm -> resource://gre/modules/Promise-backend.js:779:7 05:54:25 INFO - this.PromiseWalker.completePromise@resource://gre/modules/Promise.jsm -> resource://gre/modules/Promise-backend.js:714:7 05:54:25 INFO - get _worker/worker.onmessage@resource://gre/modules/PromiseWorker.jsm:231:9 05:54:25 INFO - Spinner.prototype.observe@resource://gre/modules/AsyncShutdown.jsm:551:9 05:54:26 INFO - ************************* https://dxr.mozilla.org/mozilla-central/rev/b7f7ae14590aced450bb0b0469dfb38edd2c0ace/browser/components/nsBrowserGlue.js#758 This is actually part of checkForPendingCrashReports() and was added by bug 1269998. Not sure if this actually affects us but it could be. I will file a separate bug for that.

Orange Factor started to track this failure on May 22nd, 2016: https://brasstacks.mozilla.com/orangefactor/?display=Bug&bugid=1274943&startday=2016-05-01&endday=2016-06-02&tree=all This were for update numbers 1 and 2. Pushlog which doesn't show something eye catching: https://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=c67dc1f9fab86d4f2cf3224307809c44fe3ce820&tochange=16663eb3dcfa759f25b5e27b101bc79270c156f2

I expanded the pushlog to a day before and after: https://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=c4449eab07d39e20ea315603f1b1863eeed7dcfe&tochange=16663eb3dcfa759f25b5e27b101bc79270c156f2 There is the landing of bug 311614, which delayed the opening of the software update dialog. This could clearly be the reason here. So expanding the timeout should help.

(In reply to Stephen A Pohl [:spohl] from comment #24) > I didn't catch the question for the n-i here. Could you clarify? Sorry, originally I wanted to put ni? on you but then decided to only CC you. Then I missed to remove the ni? request. Given that this was a kinda long outstandig ui issue, the problem here is that we expect the software update window to appear immediately after a restart: https://dxr.mozilla.org/mozilla-central/rev/dbe4b47941c7b3d6298a0ead5e40dd828096c808/testing/firefox-ui/harness/firefox_ui_harness/testcases.py#321 I think a simple Wait.until() call should do the trick by killing this race. Also we shouldn't have to rely on the sessionstore-windows-restored observer notification which is not yet supported by Marionette (bug 1300709).

Happy to take a patch if you have one but as it is not a recent regression...
