+
+ REGRESSION (r172771): Amazon product page becomes unresponsive after swiping back to it
+ https://bugs.webkit.org/show_bug.cgi?id=136260
+ <rdar://problem/18107826>
+
+ Reviewed by Dan Bernstein.
+
+ Previously, when a swipe ended up performing a same-document navigation,
+ we would never get didFinishLoadForMainFrame nor didFirstVisuallyNonEmptyLayoutForMainFrame
+ nor would we even get didHitRenderTreeSizeThreshold in all cases, so we would never
+ remove the swipe snapshot. Previous implementations removed the snapshot on
+ didSameDocumentNavigation for the main frame if the navigation type was Replace or Pop,
+ so we will match that behavior.
+
+ Also, reinstate the watchdog that starts at swipe-end which would have prevented
+ this bug from forever breaking the view it was associated with.
+
+ Also, defend against removing the snapshot before the swipe has finished (before
+ we have even caused the navigation that we're watching for the effects of).
+
+ * UIProcess/API/mac/WKView.mm:
+ (-[WKView _didSameDocumentNavigationForMainFrame:]):
+ * UIProcess/API/mac/WKViewInternal.h:
+ * UIProcess/PageClient.h:
+ * UIProcess/WebPageProxy.cpp:
+ (WebKit::WebPageProxy::didSameDocumentNavigationForFrame):
+ * UIProcess/ios/PageClientImplIOS.h:
+ * UIProcess/ios/PageClientImplIOS.mm:
+ (WebKit::PageClientImpl::didSameDocumentNavigationForMainFrame):
+ * UIProcess/mac/PageClientImpl.h:
+ * UIProcess/mac/PageClientImpl.mm:
+ (WebKit::PageClientImpl::didSameDocumentNavigationForMainFrame):
+ Plumb main-frame same-document navigation notification from WebPageProxy
+ to ViewGestureControllerMac via PageClient and WKView.
+
+ * UIProcess/mac/ViewGestureController.h:
+ * UIProcess/mac/ViewGestureControllerMac.mm:
+ (WebKit::ViewGestureController::ViewGestureController):
+ (WebKit::ViewGestureController::beginSwipeGesture):
+ (WebKit::ViewGestureController::endSwipeGesture):
+ Keep track of whether a swipe is currently occurring. We can't use
+ activeGestureType for this because the swipe currently remains the "active"
+ gesture until the snapshot is removed.
+
+ Reintroduce the old swipeWatchdogTimer (and rename the shorter timer that starts
+ when we get a visually non-empty layout) so that we will always remove the
+ snapshot after 5 seconds, even if we haven't committed the load.
+ This could lead to flashing back to the old content if we fail to get a single
+ byte for 5 seconds, but that is a rare case and should eventually get additional
+ special treatment (dropping the tiles until we do get content, or some such).
+
+ (WebKit::ViewGestureController::didHitRenderTreeSizeThreshold):
+ If a swipe is still in progress, we haven't done our navigation and thus
+ don't care about render tree size changes.
+
+ (WebKit::ViewGestureController::didFirstVisuallyNonEmptyLayoutForMainFrame):
+ If a swipe is still in progress, we haven't done our navigation and thus
+ don't care about layouts.
+
+ Stop the 5 second overall watchdog if we start the 3 second after-visuallyNonEmptyLayout
+ watchdog. This means that the snapshot could stay up for a maximum of 8 seconds
+ for a very, very slow load.
+
+ (WebKit::ViewGestureController::didFinishLoadForMainFrame):
+ If a swipe is still in progress, we haven't done our navigation and thus
+ don't care about loads that complete.
+
+ (WebKit::ViewGestureController::didSameDocumentNavigationForMainFrame):
+ Remove the swipe snapshot after painting if we do replaceState or popState.
+
+ (WebKit::ViewGestureController::removeSwipeSnapshotAfterRepaint):
+ If a swipe is still in progress, we shouldn't remove the snapshot yet.
