As test author, please may you take a look at why this has recently regressed - I'm keen to minimise our Android oranges so that people start to take the platform seriously again. If you don't have the cycles to look now, that's fine - just let me know and I can disable just on Android. Cheers :-)

There have been no recent editor changes but I'm testing the stuff which landed before it to see which one is at fault.
Flags: needinfo?(ehsan)
I retriggered a bunch of tests on the revisions before the first revision on which we've seen this, and so far it seems like this is a regression from bug 805766. I'll back out that patch to see if it helps.
Blocks: 805766
Backed out bug 805766.
Hmm, it's odd... The patch of bug 805766 just changes the IME state before the first focus event. And only on Android??

When it failed, the caret is moved to next to the 13th character. That is the same length as "EDITED TWICE ". nsTextStateFrame notifies nsWindow of selection change and text change on Android. This could be done asynchronously. http://mxr.mozilla.org/mozilla-central/source/content/events/src/nsIMEStateManager.cpp#768 http://mxr.mozilla.org/mozilla-central/source/content/events/src/nsIMEStateManager.cpp#802 And then, nsWindow for Android notifies native IME of the notified changes. And then, Android IME might set selection again. These might be also done asynchronously, but I'm not sure.
Oops. So, I guess that setting selection from Android's widget may be done after the new window is available.
Jim: Is the last paragraph of comment 40 correct? I.e., Android's IME might set selection on different window if the old widget has already lost focus? If that is NOT correct, we can fix this bug by checking if the widget has already been gone. Otherwise, I have no idea. I think that we need to disable the test on Android or give enough delay before calling sendString() in the test.
Note that nsTextStateManager is used only on Android (in default settings).
Yes. It's possible (In reply to Masayuki Nakano (:masayuki) (Mozilla Japan) from comment #42) > Jim: > > Is the last paragraph of comment 40 correct?

Yes, notification to native IME on Android is asynchronous, so I think it is possible for it to set selection on a different target. In that case, this is an Android side bug and I will fix it. > If that is NOT correct, we can fix this bug by checking if the widget has > already been gone. Otherwise, I have no idea.

Thank you, Jim. I'll confirm if my investigation is correct.
Okay, I confirmed that my investigation must be right. I removed two characters from input characters after go back. https://hg.mozilla.org/try/rev/28b2a515b171 Then, I got this result: https://tbpl.mozilla.org/php/getParsedLog.php?id=16846737&tree=Try > 82 ERROR TEST-UNEXPECTED-FAIL | /tests/docshell/test/navigation/test_bug386782.html | Editing failed. - got <p>contentEditEDITED able</p>, expected EDITED <br><p>contentEditable</p> I'll write a test patch for nsTextStateManager but I guess that we need something in Android widget too.
Ah, but it should be done after bug 806996.
This decreases the frequency of this orange. However, it doesn't become zero. So, I think Android widget also has similar issue as I mentioned. # This patch depends on the patches for bug 806996.

If it's long, we should disable the test on Android since the backed out patch is important for Android too. The random orange means that nsTextStateManager starts working with designMode editor on Android. So, without the backed out patch, Android widget isn't received the text change notification and selection change notification on designMode editor.
This patch should work. It's on the try server here, https://tbpl.mozilla.org/?tree=Try&rev=c971627af38e. But how do I know it fixed the problem? I ran mochitest-3 a few times; is that enough?

I think that 10 or 20 times is enough. I triggered them.
Ah, did you include the backed out patch? I guess you didn't so. I pushed all patches. https://tbpl.mozilla.org/?tree=Try&usebuildbot=1&rev=cca92e09d2cc

Comment on attachment 679607 [details] [diff] [review] nsTextStateManager shouldn't notify widget of selection changes and text changes after IME loses focus SelectionChangeEvent and TextChangeEvent shouldn't notify widget if Destroy() of nsTextStateManager which created them has already been called. In other words, if IME is already notified of losing focus, IME shouldn't receive the change notification.

Comment on attachment 680260 [details] [diff] [review] Fix out-of-order IME events during focus change (v1) This patch disables IME event handling in Gecko during a focus change. If not disabled, events from Java to Gecko may be in mid-flight when focus changes to a new editor. The new behavior is as soon as Gecko is notified of a blur, we disable events handling. Then on focus, Gecko notifies Java. Java first synchronizes, and then sends an acknowledgement back to Gecko. Gecko then finally re-enables events handling. This way, any events in-flight during the blur are discarded.

What do you think about combining the enums into GeckoEditableListener? Seems to be the logical place since the notify methods are defined there.

Status: RESOLVED → REOPENED
Resolution: FIXED → ---
Turns out my fix for the Java side was not complete. I will have a better fix soon.
The old patch had one rarer race condition where there is a focus and blur on the Gecko side before the Java side could acknowledge the focus. To Gecko, it looks like this: Focus (mask events = true) Blur (mask events => true) Acknowledge (mask events => false) <-- should be true because we don't have focus at this point Therefore, to Gecko, it looks like there was a second focus, but in fact the acknowledgement was for the first focus. This new patch uses a counter to make sure that we don't run into this: Focus (mask events = 1) Blur (mask events => 2) Acknowledge (mask events => 1) <-- stilled masked
Attachment #682062 - Flags: review?(cpeterson)
I moved the OnIMEFocusChange(true) call to outside of the constructor because of a scenario like this, > CreateTextStateManager() > \- nsTextStateManager() > \- OnIMEFocusChange() > \- <IME query events> > \- Editor::PostCreate() > \- <...> > |- DestroyTextStateManager() > |- <...> > |- CreateTextStateManager() When DestroyTextStateManager() is called, because nsTextStateManager() has not returned yet, sTextStateObserver is still null, and DestroyTextStateManager() simply returns. This is bad because CreateTextStateManager() is called next and it creates a new text state manager. But because we are already in CreateTextStateManager() before, two nsTextStateManager are created, and one of them is leaked. Also this causes a mismatch in OnIMEFocusChange(true) and OnIMEFocusChange(false) calls.

Also this causes > a mismatch in OnIMEFocusChange(true) and OnIMEFocusChange(false) calls. Are you sure this case? CreateTextStateManager() is called after the editor receives focus event. So, nsEditor::PostCreate() must be called at least once. nsEditor::PostCreate() can be called two or more times, I'm sure the situation, but I confirmed it. So, it could be possible for your scenario. However, I'm not sure if that happens by query event.

So, this must be called after that. Okay, we should rename the nsTextStateManager::nsTextStateManager() with nsTextStateManager::Init() again. And its constructor should just reset mObserving. And then, you don't need to check mRootContent before calling OnIMEFocusChange(true) since it's already been done. However, after calling OnIMEFocusChange(true), you should do: // OnIMEFocusChange(true) might cause recreating nsTextStateManager // instance via nsIMEStateManager::UpdateIMEState().

Addressed review comments. I am working on a test that I will post soon. Here's a stack of the problem occurring.
