Since, in Windows, the tabbar overlays the "nonclient" area, TrackMouseEvent
will report a WM_MOUSELEAVE when you move your mouse when dragging a tab.
So, suspend mouseleave tracking when capturing and resume when we end capture.
A nice effect of TrackMouseEvent is that it'll immediately post a WM_MOUSELEAVE
if called when the mouse is outside the client area, so when capture ends, we
are either over the client area and tracking resumes or we aren't and we get
an immediate WM_MOUSELEAVE.
XUL documents don't have a root scroll frame, so this would early return and prevent any of the tiling and max texture size code from running.
The root element of XUL documents likely only ever has zero-margin displayports, and they are not scrollable, so it may not be important.
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.
Handle all text change scenarios efficiently but correctly. In
particular, when we have a pending "replace text" action, make sure we
preserve old and new spans as much as we can, and make sure we merge the
text from the pending action with the actual changed text.
Use an Activity as the Context when we have one. This avoids the crash
and also avoids an ugly black flash when you cancel the intent chooser.
When we don't have an activity, use an application context and add the
new task flag.
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.
GeckoThread.queueNativeCallLocked tries to execute a queued native call
if it's already overdue, but it incorrectly checked that the queue is
not empty. That check is not necessary, and an overdue native call
should always be executed. One-line patch, r=me.
This patch:
- Maintains a consistent ordering between the lists of fields in the
FrameMetrics constructor, operator==, IPC read/write functions, and the
actual order of fields in FrameMetrics. As part of this, missing default
initializers are added to the FrameMetrics constructor, and fields omitted
from the operator== are explicitly noted.
- Moves all the boolean values to the end of the set of field (for better
packing).
- Moves the scroll id and parent scroll id to the front of the list, so that
the operator== can fail faster in the common case.
