Dave, is there a specific reason this test is using waitForFocus in the domwindowopen handler? locally I see this test perma failing, while with a simple load event it works fine. I also see a globalwindow assertion, but it disappears with the fix for bug 651315, since this uses openDialog could be related.

When we first landed it in bug 610661 we found it failed with just a load handler.
I've also very commonly seen issues when attempting to close windows that have only just opened but haven't fully got focus on linux so I'm not sure I'd want to take this. Why would it be failing for you with waiting for focus?
Comment on attachment 527898 [details] [diff] [review] tentative patch Review of attachment 527898 [details] [diff] [review]: This is something that I'd only expect to make things worse unless waitForFocus is broken in some way, so I don't think we should take it.

Why would it be failing for you with waiting for focus? I don't know, but I was able to reproduce failures constantly and this bug demonstrates that something is broken. FWIW bug 521233 is still open.
Something interesting I found is that this test always asserts, see bug 511467 comment 4. A workaround to the assertion is to enqueue the aManagerWindow.close() call in close_manager, so that the docshell is destroyed after the modal dialog dismissal is completely handled. I have no idea if there is a relation with the missing "unload" event though :(

Taking a quick look to see if I can find anything. One interesting point from the last log: 22:32:17 INFO - TEST-INFO | chrome://mochitests/content/browser/toolkit/mozapps/extensions/test/browser/browser_about.js | About dialog opened, waiting for focus 22:32:17 INFO - TEST-INFO | chrome://mochitests/content/browser/toolkit/mozapps/extensions/test/browser/browser_about.js | must wait for load 22:32:17 INFO - TEST-INFO | chrome://mochitests/content/browser/toolkit/mozapps/extensions/test/browser/browser_about.js | must wait for focus 22:32:18 INFO - TEST-INFO | chrome://mochitests/content/browser/toolkit/mozapps/extensions/test/browser/browser_about.js | Saw about dialog 22:32:18 INFO - TEST-PASS | chrome://mochitests/content/browser/toolkit/mozapps/extensions/test/browser/browser_about.js | The correct add-on about window should have opened 22:32:18 INFO - TEST-PASS | chrome://mochitests/content/browser/toolkit/mozapps/extensions/test/browser/browser_about.js | window.arguments[0] should refer to the add-on object 22:32:18 INFO - TEST-INFO | chrome://mochitests/content/browser/toolkit/mozapps/extensions/test/browser/browser_about.js | About dialog closed, waiting for focus on browser window 22:32:18 INFO - TEST-INFO | chrome://mochitests/content/browser/toolkit/mozapps/extensions/test/browser/browser_about.js | must wait for focus 22:32:18 INFO - [Parent 1672] WARNING: Should not try to set the focus on a disabled window: file c:/builds/moz2_slave/m-in-w32-d-0000000000000000000/build/dom/base/nsGlobalWindow.cpp, line 6411 which probably confirms Mak's observation oh so long ago, that the timing is racy between closing the modal dialog and waiting for focus to come back to the main window.

If we take the approach of fixing waitForFocus(), what I see happening is that when SimpleTest.waitForFocus calls SpecialPowers.getFocusedElementForWindow(), the call chains down to nsFocusManager::GetFocusedDescendant() at http://dxr.mozilla.org/mozilla-central/source/dom/base/nsFocusManager.cpp#266 That method follows the 'window->getFocusedNode()' chain to its tip, without checking any other properties of the windows it's walking through. In our failure case, it returns a pointer to a window that has its 'enabled' flag set to false. I don't know the structure of the C++ window tree that well, but I'm guessing this happens when the modal child window that was focused is closed, but not everything is cleaned up yet. If that's not intentional, cleaning up the window tree so that we never leave a !enabled window as the leaf of the getFocusedNode() chain would make this problem go away. We might be able to paper over this by modifying SimpleTest.waitForFocus (or SpecialPowers.getFocusedElementForWindow) to walk up the window's parent chain, if nsFocusManager::GetFocusedDescendant returns a !enabled window. The alternative is to modify the test to not use waitForFocus(); in that case we'd need some other way to reliably tell when the main AddonManager window gets focus back from the pop-up. Could we get this just by hanging a focus observer directly on the AddonManager window before we start the pop-up? That's what I'll look at next.
Ehsan's fought similar battles with other tests in the past. Maybe he has some ideas too :)

Yeah, looking through the code, the enabled flag actually lives on the widget (see nsWindow::IsEnabled), and I believe that is set to false when we tear down the OS level widget which happens as part of closing the window. Note that closing the window doesn't destroy the DOM object. > If that's not intentional, cleaning up the window tree so that we never > leave a !enabled window as the leaf of the getFocusedNode() chain would make > this problem go away. > > We might be able to paper over this by modifying SimpleTest.waitForFocus (or > SpecialPowers.getFocusedElementForWindow) to walk up the window's parent > chain, if nsFocusManager::GetFocusedDescendant returns a !enabled window. > > The alternative is to modify the test to not use waitForFocus(); in that > case we'd need some other way to reliably tell when the main AddonManager > window gets focus back from the pop-up.

I'm not sure what the above proposals are trying to fix here. Which window are we closing and which one we're focusing here? If I'm reading the test code right, we focus the about window, call .close() on it, and wait for domwindowclosed to be dispatched and then try to focus the main window. Is it here where we're seeing the disabled window? That seems like a bug! Or am I missing something? (BTW, this is exactly the same pattern that I've been seeing in bug 772823 and I tested a patch there on the try server which fixes this issue by reordering these operations. We can do the same thing here but it looks like we're on our way to finally understand the root cause of these failures! Also, note that Neil Deakin is on vacation until the 29th.)

The sequence is: Open Addon Manager window Request 'about' window for one add-on Wait for domwindowopen (hopefully it's the 'about' window) waitForFocus() Close 'about' window Wait for domwindowclose waitForFocus() (hopefully on the Addon Manager window) ... repeat steps for another add-on The last TBPL test failure was in the last step, where we wait for Addon Manager to get the focus back. I have a WIP patch that just waits for onfocus on the Addon Manager, rather than using the 'waitForFocus()' test hook; it works fine on my desktop, I'm cleaning up a couple more things before I sent it to Try.

I wonder if bug 608820 has the same root cause.
Based on a quick look at the code & TBPL log for bug 608820, there is a different (as yet unknown) mechanism at fault. That will have to be next week's orange squash ;->

Thanks! > The last TBPL test failure was in the last step, where we wait for Addon > Manager to get the focus back. OK but I still don't understand this part, specifically the theory in comment 448. So, waitForFocus() calls getFocusedElementForWindow in two places, once in <http://mxr.mozilla.org/mozilla-central/source/testing/mochitest/tests/SimpleTest/SimpleTest.js#683> and then in <http://mxr.mozilla.org/mozilla-central/source/testing/mochitest/tests/SimpleTest/SimpleTest.js#736>. Which one of these calls were you talking about in comment 448? I'm specifically trying to understand where we encounter the window with the 'enabled' flag set to false and where that window comes from. That's basically where our bug is. > I have a WIP patch that just waits for > onfocus on the Addon Manager, rather than using the 'waitForFocus()' test > hook; it works fine on my desktop, I'm cleaning up a couple more things > before I sent it to Try. I'm afraid that won't work, we can never assume that the focus will sanely go back to the window that we expect it to go back to in our tests which is why we had to add waitForFocus in the first place. The reason is that the focus is a shared state across all of the apps running on the same desktop/OS so any other window that is opened on the test machine can mess with the onfocus idea. (Note that waitForFocus is really badly named, it should probably be called focusAndWaitForLoad as it actually ensures that the window is focused and the content inside it has finished loading -- see the discussion in bug 564276.)

Ah, I see. (aside: browser_about.js might work without focus, because it does all its operations by calling handlers directly rather than by simulating keypresses and clicks; since the window we're waiting for in this case is modal, we actually have synchronous behaviour at the JS API level so we might get away without onfocus. I did a try run with no wait for focus on the AddonManager window and it passed: https://tbpl.mozilla.org/?tree=Try&rev=61e8449bc257) But to answer your question, we're getting the log message "must wait for load" at SimpleTest.js:729 just before the "WARNING: Should not try to set the focus on a disabled window", which implies it's the call at SimpleTest.js:683 to retrieve 'childTargetWindow' - search for the messages at 22:32:18 in https://tbpl.mozilla.org/php/getParsedLog.php?id=37679337&full=1&branch=mozilla-inbound#error0 Is there useful information about the window available through the JS API? It would be easy add some diagnostic output to SimpleTest.js in cases where childTargetWindow.enabled is false.

Yes, it's location.href would be very interesting to know (see the getHref function inside waitForFocus.) So would the |closed| property of the window object. It seems that based on the above, we're somehow getting the about dialog window as a result of getFocusedElementForWindow on the _main_ window, which is frightening! Can you please post the diagnostic patch to try?
Flags: needinfo?(ehsan)
I ran this on Try and retriggered a few of the tests (the test i'm working on is in the bc3 set). I tried two things in this patch: add some diagnostics to see which window we're trying to focus on in waitForFocus(), and an alternate version of browser_about.js that specifies we want to wait for the Addon Manager window rather than picking up the default global Window. I'm not sure if this will help - we're running this in a 'domwindowclosed' event handler for a modal dialog; if we're losing the race such that the global 'window' object points at the (closing, but still around) modal dialog rather than the Addon Manager, I'd expect any attempt to set focus on the Addon Manager window to be blocked by the modal dialog. Unfortunately the intermittent failure hasn't shown up in the Try test runs yet, so I can't tell whether either of these approaches helps. https://tbpl.mozilla.org/?tree=Try&rev=8db5624369b5&showall=1

This patch takes a different approach - first, in an attempt to improve clarity I rewrote what I could using the add_task() test driver. Second, because the addon 'about' dialog is modal and all the test operations are executed by calling underlying handlers directly rather than by simulating UI interactions, the test might not need to wait for focus on the addon manager window at all. I put this through one Try run and it was all green, but that's not much evidence given how intermittent the failure is.

If the add-on manager is opened in a tab, passing either |window| or |gManagerWindow| here should not change the semantics of the test, but we'll see on try. But to be honest, I don't understand the racing theory in comment 457. |window| should always point to the browser window running the tests, not sure how it can point to the modal dialog here...

BTW, I'm going to laugh (read: cry) if this is a heisenbug where adding logging disrupts the test just enough to avoid it failing.

The global "window" will never point to the modal dialog. Now it is possible the attempt to focus could be blocked but I think it shouldn't be because we only do it after the modal has been completely closed.

I thought the call in the test that pops up the dialog: gManagerWindow.gViewController.doCommand("cmd_showItemAbout", selectedItem.mAddon); is completely synchronous - that it won't return until the modal dialog is closed & gone. Is that not true?

OK, I'm still learning how the nesting of DOM UI elements works - I had seen some debug messages that made me think I was in a different window hierarchy when the modal was up, but now I've figured out that I was misreading the context of those messages. That brings me back to my even-earlier theory (https://bugzilla.mozilla.org/show_bug.cgi?id=632290#c448), that the code we're running under the 'domwindowclosed' notification is racing with the teardown of the modal such that we sometimes find the object at the end of the thing->getFocusedNode() chain is something that can't actually be focused, or that it's OK when we get it but by the time waitForFocus() tries to reset focus on it, it's closed.

Plausible, there might be an even later window notification we need to use, maybe outer-window-destroyed. I really forget what order all these window notifications happen in

getFocusedNode doesn't (shouldn't) look at the DOM of another document (namely the modal window), right? That's basically the main problem I have understanding the theory in comment 448.

Irving, any new ideas here by chance? Would love to not take this failure into another ESR release.
Flags: needinfo?(irving)
In the hope that we can reduce this nasty intermittent, I've reworked the test a bit - aside from switching to Task-style async, this patch makes sure we unwind the stack before acting on the window in the 'domwindowopened' event handler, and waits for the modal dialog call to return (thus also unwinding the stack) before waiting for focus to come back to the AddonManager main window. This doesn't address any of the underlying concerns about FocusManager, but hopefully letting the event loop spin renders that moot. https://tbpl.mozilla.org/?tree=Try&rev=420afb446af7

Actually, I've been looking at it the last couple of days, along with some other focus related test failures. I think the Linux failures may be a slightly different cause. I've added some logging but they are hard to reproduce with the logging added. If I can't get anything more in a few days, I'll disable it.
Over to Neil but yes if we can't figure this out just disable it. This is a little-used UI feature that frankly has little that could go wrong (and if it did it wouldn't be the end of the world) so I'd be fine with no testing.
