One work-around for the bug is to ensure that our content root is in a
document when flushing IME changes, because when an input becomes
hidden, the previous content root is removed from the document.
Flush IME changes when committing or canceling the composition, before
sending a notification, so that the Gecko and Java sides are on the same
page.
Also, use the GeckoEditableListener constants when calling notifyIME so
we don't rely on the Gecko platform constants having the same values as
our Java constants.
When Java is changing the composition, we should ignore the Gecko
selection. However, when Gecko is committing its composition, we should
not be ignoring the corresponding Gecko selection change. In other
words, we should only ignore selection changes when we know the change
is from Java.
Remove obsolete SIZE_CHANGED event and its handler in nsWindow. Also
remove some other supporting code (such as gAndroidBounds and the
FORCED_RESIZE event) that should be unnecessary by now.
Convert the SIZE_CHANGED event to a native method in GLController, and
carry over the SIZE_CHANGED implementation to the new implementation in
GLController. Some other changes were made for correctness in handling
size changes.
This patch removes dozens of ToUnknown/FromUnknown conversions and doesn't add
any new ones, which is nice. It also removes UntypedDevPixelsToCocoaPoints(),
which is no longer needed.
With APZC supporting multiple nsWindows, this patch removes some
obsolete APZ code, including the previous implementation of
NativePanZoomController native methods in AndroidJNI.cpp, and the
various static members of nsWindow.
This patch adds a way to attach a particular NativePanZoomController
instance held by LayerView to a particular nsWindow instance. Because
LayerView already calls GLController.SetLayerClient during
initialization, this patch renames it to attachToJava and modifies it to
accept an additional NPZC parameter. In the new AttachToJava
implementation, we create or reuse a NPZCSupport object and associate it
with the NPZC instance.
This patch adds the NPZCSupport class to nsWindow and use it to
implement the NPZC native methods that were implemented in
AndroidJNI.cpp. For HandleMotionEvent, the code also includes a portion
from AndroidJavaWrapper::MakeMultitouchEvent.
When waiting for the compositor to shut down, it's possible for
nsWindow::DrawWindowunderlay and DrawWindowOverlay to be called. In that
case, the GL controller is already destroyed, and we should just bail.
When nsWindow closes, notify GLController to shut down. To ensure any
pending calls on the UI thread are processed first, post a Runnable to
the UI thread that disposes the GLController on the UI thread.
To guarantee that GeckoInputConnection and GeckoEditable are not used by
GeckoView after GeckoEditable has been destroyed, we need to make sure a
certain sequence is followed. We should first unset the
InputConnectionListener in GeckoView on the UI thread; then unset the
GeckoEditableListener on the IC thread; and finally finish destroying
the GeckoEditable instance through disposeNative. This patch merges this
logic with the initialization logic in GeckoEditable.onViewChange, so
that onViewChange can be used for both initialization and destruction.
LayerView used to call GeckoLayerClient.onGeckoReady directly if Gecko
is sufficiently loaded. However, onGeckoReady indirectly calls
GLController.createCompositor, and it's possible for the
createCompositor event to be prioritized so that it happens before we
initialize GLController, causing a crash. This patch moves the
onGeckoReady call to the Gecko thread, after GLController is
initialized, to avoid this race condition.
Only three GLController events -- CreateCompositor, PauseCompositor, and
OnResumedCompositor should be prioritized through GLControllerEvent. The
other GLController events should follow the normal event queue ordering
to prevent race conditions.
When we have a Java exception in native code, the Java stack in the
exception will not be very useful because the top frame is the native
entry point. In this case, the native stack is more useful. However,
currently we don't get a good native stack in this situation because we
go through Java when handling the exception, and the native stack we get
will have a lot of unknown frames inside libdvm or libart. This patch
makes us stay in native code when handling an uncaught exception from
native code, so that we get a good native stack.
This patch moves the SyncRunEvent logic from GLControllerSupport to
nsAppShell, as it could be useful elsewhere. This patch fixes a race
condition related to shutdown, where a deadlock could occur if Gecko
shuts down when another thread is waiting for a synchronous event to
finish running. This patch also fixes a crash on shutdown when we tried
to create a mutex after the deadlock detector has shut down.
When getting nsAppShell from another thread, there could be a race with
nsAppShell being destroyed on the main thread. This patch makes the raw
nsAppShell pointer only accessible from the main thread, and use a
static mutex to coordinate accessing nsAppShell from other threads.
This patch changes onAttachedToWindow in GeckoView, so that if we have
states that have been restored, we use those states for initialization
instead of creating new states (e.g. opening a new nsWindow). Because
the GLController instance is associated with the nsWindow instance, we
need to keep the GLController instance as part of our saved states. This
patch also adds a reattach method to GeckoView.Window, because
GeckoEditable needs to be notified when its target View changes.
This patch makes GLContextProviderEGL create EGL surfaces through
nsWindow/nsIWidget on Android. nsWindow then calls GLController in Java
to actually create the surface.
