        [WK2][iOS] UIProcess may get killed because it is taking too long to release its background task after expiration

        The UIProcess may get killed because it is taking too long to release its background task after its expiration handler
        was called. The reason is that the background task's expiration handler was sequentially sending a ProcessWillSuspendImminently
        synchronous IPC to each of its child processes and only then ends the background task. By the time we receive the response from
        all child processes, it may be too late and we get killed.

        To address the issue, we now:
        1. Send the ProcessWillSuspendImminently asynchronously so that all processes can do their processing in parallel
        2. After 2 seconds, the UIProcess releases the background task (We get killed after ~5 seconds)

        Also, to make sure that the UIProcess supends promptly, we now make sure we never start a new background task *after*
        the app has been backgrounded. The intention of our background task is too finish critical work (like releasing locked
        files) after the app gets backgrounded, not to start new work and delay process suspension.

        This approach allows to call the delegate even if the quota request comes from a service worker.

        This seems to be an omission in the specification. While it does mention that the in-view

        [iOS] Cannot scroll to beginning of document after scrolling to end of document and vice versa via key commands

        Reviewed by Brent Fulgham.

        Following the fix for <rdar://problem/49523065>, UIKit no longer emits a keyup event for a Command-
        modified key. This breaks WebKit's own implementation of key command handling for scrolling to the
        beginning or end of the document (triggered using Command + Arrow Up and Command + Arrow Down,
        respectively) because it watches for keyup events to reset state after initiating a scroll. If state
        is not reset then the scroll key command logic becomes confused and may not perform a subsequent scroll.
        It seems like we can actually get away with supporting these key commands and future Command modified
        commands by preemptively reseting state on keydown if the Command modifier is held down. If this does
        not work out then we can do something more complicated.

        Reviewed by Tim Horton.

        After r244775, when running back-to-back layout tests on iOS that simulate taps in the same location, the double
        tap gesture recognizer for recognizing double clicks ends up recognizing instead of the single tap gesture
        recognizer in the subsequent test. This means that click handlers in the subsequent test will fail to recognize,
        unless the element with the click handler is also accompanied by a dblclick handler.

        To avoid this, we reset the double click gesture recognizer when navigating; this has the additional effect of
        making it such that the second page doesn't end up observing a dblclick when the first click was only sent to
        the first page.

        [PSON] Prevent flashing when the process-swap is forced by the client
        https://bugs.webkit.org/show_bug.cgi?id=197799

        Reviewed by Geoffrey Garen.

        When the process-swap is forced by the client, we would not construct a SuspendedPageProxy for
        the previous page, which would cause a white/black flash upon navigation on macOS. The reason
        we did not construct a SuspendedPageProxy is that it would be unsafe to keep the page around
        in this case because other windows might have an opener link to the page when the swap is forced
        and we need those opener / openee links to get severed.

        The new approach to maintain the Web facing behavior without flashing is to create a suspended
        page proxy for the previous page when the process swap is forced by the client. We then close
        the page as soon as we can do so without flashing (when pageEnteredAcceleratedCompositingMode()
        has been called).

        Do not wait until requestPermission() is called to fire deviceorientation events if permission was already granted
        https://bugs.webkit.org/show_bug.cgi?id=197750

        Reviewed by Geoffrey Garen.

        The UIProcess remembers previous device orientation permission decisions per origin for the duration of the browsing
        session. However, the WebContent process was not aware of previous decisions and would therefore not fire any
        deviceorientation / devicemotion events until the JS has called requestPermission(). This patches addresses this
        problem by having the UIProcess communicate any previous permission decision for the origin via WebSitePolicies.

        It was getting complicated to manage the coordination between WebKitAdditions
        and WebKit without having to split up the includes into multiple files
        or have lots of duplication.

        Instead, WebKitAdditions will now define a USE macro which can be used
        in various places through WebKit.

        For now, only create a keyboard when WKContentView becomes first responder if a hardware keyboard

        We can do better and by that I mean be lazier. We'll do this <https://bugs.webkit.org/show_bug.cgi?id=197746>.

        In r241734 we unified the key event handling code paths so we use exactly one for both software and
        hardware key events. We took a simple approach of always requesting UIKit to create a keyboard when
        the WKContentView becomes first responder. We did this so that we could continue listening for hardware
        key events even when a non-editable element is focused and dispatch DOM events. As it turns out, always
        creating a keyboard is expensive and caused a ~1% slowdown in page load time on iPad.

        Fixes an issue where it is not possible to submit a <form> with target = "_blank": a form that
        opens a new window.

        By default we only allow popups to open if they were user initiated (like when a person clicks
        on a link). We achieve this by putting a token on the stack, called the UserGestureToken when
        WebCore processes an event from WebKit. So long as this token is on the stack we consider
        all requests to open a popup to be user initiated. And we implicitly submit a form when pressing
        the Return key in an HTML input element during the processing of a TextInputEvent dispatched as
        part of inserting a '\n' into the field. On Mac, the keydown dispatches a TextInputEvent synchronously.
        However on iOS text insertion, and hence a dispatch of a TextInputEvent event, occurs asynchronously
        with respect to the keydown event. So, by the time the UI process calls back to the WebProcess
        to perform the text insertion of '\n' we have long since popped the UserGestureToken off the stack
        and hence we disallow opening a popup. To fix this, when -insertText is called we query the keyboard
        to determine if it's being called by the keyboard. If it is then we can assume that this is
        part of key event handling and hence was initiated by the user. We can pass along this detail
        to the WebProcess for it to push a new UserGestureToken onto the stack.

        For now we only track whether text inserted by the keyboard was user initiated or not. In
        <https://bugs.webkit.org/show_bug.cgi?id=197721> we will fix this up for all editing commands.

        We clear the touch actions for a given touch identifier when the matching touch is released in -[WKContentViewInteraction _handleTouchActionsForTouchEvent:].
        This happens before -[WKScrollingNodeScrollViewDelegate scrollViewWillEndDragging:withVelocity:targetContentOffset:] is called and thus, which we correctly
        respected the touch actions during the panning gesture, we would not be able to respect them during the deceleration animation. This caused the test to fail
        because it would check that no scrolling happened after the panning gesture completed, ie. during the deceleration animation.

        To work around this, we now store the touch actions for a given UIScrollView interaction in the ScrollingTreeScrollingNodeDelegateIOS object when the interaction

        We've recently made it so that the WebContent process destroys its WebSQLiteDatabaseTracker when preparing
        for process suspension and then re-constructs it when resuming. The issue is that the WebSQLiteDatabaseTracker
        internal implementation was calling callOnMainThread() and capturing |this| to start/stop its HysteresisActivity.
        As a result, |this| could be dead by the time we're on the main thread and we'd crash.

        To address the issue, we no longer destroy the WebSQLiteDatabaseTracker when preparing to suspend. Instead, we
        set a 'isSuspended' flag on the WebSQLiteDatabaseTracker so that it stops notifying the WebProcess of changes.

        Also clean up the class a bit so that:
        1. The constructor takes in a WTF::Function instead of a NetworkProcess / WebProcess reference. This is provides
           better layering. The WebSQLiteDatabaseTracker should not need to know anything about those objects.
        2. Use RunLoop::main().dispatch() instead of callOnMainThread() since we're in WebKit2 code.

        the page perfectly follow finger, and deltas are additionally divided by Scrollbar::pixelsPerLineStep(),
        so compensate for that.

        For touchpad events, change delta multiplier to 10 to match GTK behavior, and introduce a 400px
        base width so the swipe speed doesn't change from the previous behavior.

        Because of the multiplier change, threshold for triggering the gesture with touchpad is now 4
        times larger.

        [WebAuthN] A new request should always suppress the pending request if any
        https://bugs.webkit.org/show_bug.cgi?id=191517
        <rdar://problem/46888222>

        Reviewed by Brent Fulgham.

        Previously we blocked new WebAuthN requests whenever a pending request was in progress
        to prevent background tabs from DoS foreground tabs. However, in r244938, the WebAuthN
        API was changed to restrict request handling to the focused document. Therefore, we no
        longer have a risk of DoS.

        Apart from the vanished benefit, this behavoir actually blocks new pages to use
        WebAuthN API in the period between [the previous initating page is closed, the pending
        request is hanedled/timeout].

        Also, it makes sense to have the current focused document preempt the pending request.
        Therefore, the policy will be to always cancel any pending requests whenever a new
        request is made. This will enforce the policy of handling only one request at a time.

        Note that the current implementation doesn't explicitly cancel pending requests in the
        Authenticators, which means that we could receive responses from the Authenticator that
        were meant for a previous (now cancelled) request. A follow-up patch (see Bug 191523)
        will implement an Authenticator feature to support immediate cancellation.

        In the meantime, to protect the atomicity of the request/response pair, i.e., preventing an old
        response being used for a new request, there are two safeguards:
        1) In web process, each request to UI process is paired with an incremental ID, and therefore an old
        response from UI process would have a different ID than the current request, which will then be ignored.
        2) In UI process, all responses from authenticators will be piped to the main run loop for processing.
        Therefore, when the new request comes in, the old response is either processed or waiting in the pipe.
        To prevent the latter being processed, the new request will immediately destroy any authenticators bound
        to the old response in the current run loop. Hence, in the next run loop when dealing the old response,
        the lambda will have no where to hand the response over.

        - Remove dead code in WebKit::NetworkProcess since the calls now go through NetworkConnectionToWebProcess.

        WebCore, just as we do for Mac, so that it can alter its event handling logic. Otherwise,
        we handle the event as we do now.

        Bookkeeping to track whether we need to delay showing/updating the inline candidate view.
        The concept in UIKit is deferment, but at the time of writing its simply a request to delay
        the update for 0.4 seconds. We opt into this delay only for the first key that begins
        marked text (i.e. the transition from no marked text to marked text). We do this because we
        may not have up-to-date editor state at the time UIKit is ready to show/update the inline
        candidate view for us to answer -textFirstRect and -textLastRect, which UIKit calls as part
        of computing the frame rect for the inline candidate view on screen. Once we receive up-to-date
        editor state, in -selectionChanged, we tell UIKit to layout the keyboard, which ultimately
        causes it to re-compute the frame rect for the inline candidate view and show it.

        The code in SandboxExtensionsCocoa.mm 'resolveSymlinksInPath' is pretty inefficient, and tries to reproduce (badly)
        logic that is already provided by the operating system.

        To make matters worse, 'resolvePathForSandboxExtension' was effectively performing the work of fully resolving
        symlinks twice, since NSString's 'stringByStandardizingPath' method does some of this already.

        Instead, we should just use NSString's 'stringByResolvingSymlinksInPath', which does the symlink resolution
        using more efficient logic than our 'resolveSymlinksInPath' code.

        REGRESSION (r244897): Caret may appear wider than normal after zooming to focus an editable element
        https://bugs.webkit.org/show_bug.cgi?id=197579

        Reviewed by Tim Horton.

        Fixes a couple of flaky tests (CaretSelectionRectAfterRestoringFirstResponderWithRetainActiveFocusedState and
        CaretSelectionRectAfterRestoringFirstResponder) that began failing after r244897. These tests both begin by
        focusing an editable element, which causes the web view to zoom in. The tests subsequently check that the caret
        rect is {{ 16, 13 }, { 2, 15 }}. While the specified caret rect (coming from EditorState) is {{ 16, 13 }, { 3,
        15 }}, the narrower caret rect is used because we take measures to preserve the width of the caret relative to
        the view (see the inverse scaling logic in -[WKContentView selectedTextRange] for more details).

        See below for more details.

        * UIProcess/ios/WKContentViewInteraction.h:

        Remove _isZoomingToRevealFocusedElement, now that we don't need it anymore (see -observeValueForKeyPath:).

        * UIProcess/ios/WKContentViewInteraction.mm:
        (-[WKContentView cleanupInteraction]):
        (-[WKContentView observeValueForKeyPath:ofObject:change:context:]):

        Stop bailing from a selection update when changing scale, while zooming to reveal the focused element. This
        check was added in r239441 to prevent UIWKTextInteractionAssistant's selection scrolling logic from interfering
        with WKContentView-driven logic for zooming to the focused element. However, since r244141, this is no longer
        necessary since selection scrolling is only driven by code in the web process.

        This new update while zooming to reveal the focused element ensures that the WKTextRange returned by
        -selectedTextRange after zooming will have a width that is inversely scaled using the content view's current
        scale, such that it has a consistent width (relative to the web view) across different scales.

        (-[WKContentView _zoomToRevealFocusedElement]):
        * UIProcess/ios/WebPageProxyIOS.mm:
        (WebKit::WebPageProxy::layerTreeCommitComplete):

        Remove any attempt here to notify PageClient about editor states after focus. This logic was actually incorrect,
        since it didn't ensure that the layer tree commit that is being completed actually contained an editor state; as
        such, the "editor state" received here could be stale.

        The code in SandboxExtensionsCocoa.mm 'resolveSymlinksInPath' is pretty inefficient, and tries to reproduce (badly)

        To make matters worse, 'resolvePathForSandboxExtension' was effectively performing the work of fully resolving
        symlinks twice, since NSString's 'stringByStandardizingPath' method does some of this already.

        Instead, we should just use NSString's 'stringByResolvingSymlinksInPath', which does the symlink resolution
        using more efficient logic than our 'resolveSymlinksInPath' code.

        (WebKit::RemoteLayerTreeDrawingAreaProxy::commitLayerTree):

        Partially reverts a change in r244546, after which we commit the layer tree and scroll before updating the
        page's editor state. The purpose of this change was to ensure that UI process-side element focus scrolling logic
        would not conflict with web-process-driven scrolling logic.

        Instead, we split the existing logic in WebPageProxy::editorStateChanged into two pieces: one that updates the
        editor state (by setting m_editorState), and a second that dispatches updates to PageClient when the first
        editor state is received after focusing an element. During a layer tree commit in the UI process, we first
        update the editor state, then commit the layer tree and apply scroll position changes, and finally scroll to
        reveal the focused element if necessary.

        When an editor state is delivered to the UI process in an out-of-band update (i.e. not in a layer tree commit),
        simply dispatch the initial editor state for a focused element immediately.

        * UIProcess/WebPageProxy.cpp:

        Additionally ensure that an editor state update is scheduled. This addresses a potential source of flakiness in
        the layout test editing/selection/ios/selection-after-changing-text-with-callout-menu.html, where an editor
        state update may only be scheduled after the next layout timer fires (this is the case in custom callout menu
        actions that change the DOM but do not otherwise trigger any editing commands).

        In the problematic scenario, the client could make a change that triggers layout soon; but before the layout
        timer fires, the timer for the next remote layer tree commit could fire, such that the next layer tree commit
        would not contain the relevant editor state.

        This extra step ensures that we always *schedule* an editor state update when performing a callout menu action

        NSAttributedString conversion in a loop returns nil and WKUnknownError every other time.
        https://bugs.webkit.org/show_bug.cgi?id=197523

        Reviewed by Darin Adler.

        Caching the WKWebView was loading about:blank to unload the previous content.
        This was causing subsequent rapid conversions to fail since the blank load
        would be confused with the real content loading. Loading a blank page wasn't
        really needed, it just helped keep the cached view in a cleaner state. Instead
        of adding complexity to track the extra navigation, we can eliminate the blank load.
        Ultimately a process swap will likely happen on the next navigation, and unused
        cached views are closed quickly -- so stale content isn't held around too long.
        This also avoids extra work and speeds up conversions a bit.

        [iOS] Add a version of viewport shrink-to-fit heuristics that preserves page layout
        https://bugs.webkit.org/show_bug.cgi?id=197342
        <rdar://problem/50063091>

        Reviewed by Tim Horton.

        This patch introduces a new shrink-to-fit heuristic that attempts to lay out the contents of the page at a
        larger width in order to shrink content to fit the viewport. This is similar to existing shrink-to-fit behaviors
        used for viewport sizing in multitasking mode, except that it not only scales the view, but additionally expands
        the layout size, such that the overall layout of the page is preserved. In fact, the reason we ended up
        reverting the existing flavor of shrink-to-fit in all cases except for multitasking was that page layout was not
        preserved, which caused elements that poke out of the viewport to make the rest of the page look out of
        proportion — see <rdar://problem/23818102> and related radars.

        Covered by 5 new layout tests, and by adjusting a couple of existing layout tests. See comments below for more
        details.

        * Platform/Logging.h:

        Add a new ViewportSizing logging channel. This will only log on pages that overflow the viewport and shrink to
        fit as a result.

        * Shared/WebPreferences.yaml:

        Turn IgnoreViewportScalingConstraints off by default. This preference currently controls whether we allow
        shrink-to-fit behaviors, and is only used by Safari when it is in multitasking mode. The value of this
        preference is currenly *on* by default, and is turned off almost immediately during every page load after the
        first visible content rect update, wherein visibleContentRectUpdateInfo.allowShrinkToFit() is false.

        However, this sometimes causes a brief jitter during page load; to fix this, make the default value for
        IgnoreViewportScalingConstraints false, and change the logic in WebPage::updateVisibleContentRects to
        setCanIgnoreScalingConstraints to true if either the IgnoreViewportScalingConstraints preference (not only
        affected by an internal debug switch) is true, or WKWebView SPI is used to enable the behavior.

        Add a new hook for WebFrameLoaderClient to call into WebPage when document load finishes. Also, tweak

        non-null anyways).

        * WebProcess/WebPage/ios/WebPageIOS.mm:
        (WebKit::WebPage::setViewportConfigurationViewLayoutSize):

        Don't allow the minimum effective device width from the client to stomp over any minimum effective device width
        set as a result of the new shrink-to-fit heuristic; on some pages that load quickly, this can result in a race
        where the minimum effective device width (i.e. a value that lower-bounds the minimum layout width) is first set
        by the shrink-to-fit heuristic, and then set to an incorrect value by the client.

        In the near future, web view SPI used to set the minimum effective device width should actually be removed
        altogether, since the new shrink-to-fit heuristic supersedes any need for the client to fiddle with the minimum
        effective device width.

        (WebKit::WebPage::dynamicViewportSizeUpdate):

        When performing a dynamic viewport size update, additionally re-run the shrink-to-fit heuristic. This allows
        the minimum layout size of the viewport to be updated, if necessary. An example of where this matters is when a
        web page is *below* a tablet/desktop layout breakpoint in portrait device orientation, but then exceeds this
        layout breakpoint in landscape orientation. In this scenario, rotating the device should swap between these two
        page layouts.

        (WebKit::WebPage::shrinkToFitContentTimerFired):
        (WebKit::WebPage::immediatelyShrinkToFitContent):

        Leverage the existing capability for a viewport to have a "minimum effective device width" to grant the viewport
        a larger layout size than it would normally have, and then scale down to fit within the bounds of the view. One
        challenge with this overall approach is that laying out at a larger width may cause the page to lay out even
        wider in response, which may actually worsen horizontal scrolling. To mitigate this, we only attempt to lay out
        at the current content width once; if laying out at this width reduced the amount of horizontal scrolling by any
        amount, then proceed with this layout width; otherwise, revert to the previous layout width.

        This patch adds support for dispatching dblclick event as the result of the double tap gesture.

        1. The new double tap gesture recognizer always fires regardless of what type of action the other, existing double gesture recognizers (double-tap to zoom) trigger.
        2. The dblclick event is dispatched on the node with registered dblclick event handler unless the node prohibits double tap gesture (touch-action != auto).

        If the UIProcess holds a background assertion for itself for 30 seconds, the assertion's invalidation handler
        will get called and it is our responsibility to release this assertion or the UIProcess will get killed by the
        system. The logic in ProcessAssertion would normally do that but it would also happily try and re-take another
        background process assertion shortly after the previous one expired (and before the UIProcess got suspended).
        When doing so, the new background assertion would expire right away and we would get killed without its
        invalidation handler getting called.

        To address the issue, the logic in ProcessAssertion will now prevent taking a new background assertion after
        one expires and until the application becomes foreground again.

        [GTK] Back/forward gesture snapshot always times out
        https://bugs.webkit.org/show_bug.cgi?id=197233

        Reviewed by Michael Catanzaro.

        Delaying web process launch caused a regression where we create ViewGestureController when the
        web process doesn't yet exist. The controller immediately tries to connect to it and fails,
        and because of that never receives DidHitRenderTreeSizeThreshold() message, so navigation
        snapshot always stays until timeout after performing the gesture.

        To prevent this, create the controller in webkitWebViewBaseDidRelaunchWebProcess() instead of
        webkitWebViewBaseCreateWebPage(). Additionally, since settings are now created earlier than
        ViewGestureController, store the value of whether swipe gesture is enabled in WebKitWebViewBase
        and immediately apply it when creating the controller.

        Since there is now a point where controller is null, make webkitWebViewBaseViewGestureController()
        return null and add null checks everywhere.

        - Pass MessageReceiverName / MessageName when constructing the MachMessage rather

        - Set header->msgh_id to the right value right away instead of setting it first
          to inlineBodyMessageID and then later fixing it to be outOfLineBodyMessageID
          when the body is out of line.
        - When messageBodyIsOOL was true, we would call getDescriptorAndSkip() which
          would advance the pointer by sizeof(mach_msg_port_descriptor_t), even though
          the descriptor type is mach_msg_ool_descriptor_t. This would not matter in

        * Platform/IPC/mac/MachMessage.cpp:
        (IPC::MachMessage::create):
        Use fastZeroedMalloc() instead of fastMalloc() for safety, given that this class
        has a mach_msg_header_t flexible array member. This is what is recommended by the
        mach documentation. It is much safer because it otherwize relies on the user
        (Connection::sendOutgoingMessage()) to initialize ALL the message members
        correctly. I suspect this was the cause of <rdar://problem/44291920> because
        Connection::sendOutgoingMessage() would fail to initialize header->msgh_voucher_port
        and the MachMessage destructor would then call mach_msg_destroy(header()), which
        would mach_msg_destroy_port(header->msgh_voucher_port).

        (IPC::MachMessage::MachMessage):
        Pass MessageReceiverName / MessageName when constructing the MachMessage rather
        than setting them afterwards since they never change for a given MachMessage.

        [GTK] Back/Forward gesture interferes with scrolling
        https://bugs.webkit.org/show_bug.cgi?id=197168

        Reviewed by Michael Catanzaro.

        When the gesture is released with 0 velocity close to an edge of the webview,
        the finishing animation is way too long, and in some cases it can look like the
        gesture is already over, when it's still animating. By scrolling vertically while
        that happens, it's possible to reset animation over and over again.

        To reduce the duration in this case, instead of using maximum possible duration
        (400ms), introduce a base velocity and use it for calculating the duration if
        the actual velocity, relative to the end point, is equal to or less than 0.

        https://bugs.webkit.org/show_bug.cgi?id=197233

        Reviewed by Michael Catanzaro.

        Delaying web process launch caused a regression where we create ViewGestureController when the
        web process doesn't yet exist. The controller immediately tries to connect to it and fails,
        and because of that never receives DidHitRenderTreeSizeThreshold() message, so navigation
        snapshot always stays until timeout after performing the gesture.

        To prevent this, create the controller in webkitWebViewBaseDidRelaunchWebProcess() instead of
        webkitWebViewBaseCreateWebPage(). Additionally, since settings are now created earlier than
        ViewGestureController, store the value of whether swipe gesture is enabled in WebKitWebViewBase
        and immediately apply it when creating the controller.

        There are several places in our Xcode projects that post-process

        When either of the two WebsiteDataStore::removeData() functions calls

        Ad Click Attribution conversions are picked up in the redirect handler
        in WebKit::NetworkResourceLoader. Content blocking typically happens in
        the continued redirect request handling in the web content process and
        a blocked request comes back empty.

        We need to call the WebKit::NetworkLoadChecker in the network process
        for these specific redirects, just like we do for Ping.

        The change makes use of the existing function
        NetworkLoadChecker::enableContentExtensionsCheck() for this purpose.

        In essence, this change makes it possible to block all conversions made

        <rdar://problem/50048318>

        Reviewed by Alex Christensen.

        The issue is that when doing a history navigation with form data, we try to resubmit the form.
        We initially use the ReturnCacheDataDontLoad cache policy without prompting the user to get
        cached data. If this fails, we sent a DidFailProvisionalLoadForFrame IPC to the UIProcess but
        the WebContent process actually retries the load with ReturnCacheDataElseLoad cache policy.
        This new load triggers a new decidePolicyForNavigationAction.

        This would cause trouble with process-swapping because we normally destroy the
        ProvisionalPageProxy as soon as we receive a DidFailProvisionalLoadForFrame IPC from the
        provisional process. As a result, the provisional process would not be able to retry.

        To address the issue, we add pass a flag with the DidFailProvisionalLoadForFrame IPC to
        if the load will continue or not. When this flag is set, the UIProcess does not destroy
        the provisional page.

        Regression(r243767) WebFrame::m_navigationIsContinuingInAnotherProcess flag is never reset
        https://bugs.webkit.org/show_bug.cgi?id=197144

        Reviewed by Darin Adler.

        WebFrame::m_navigationIsContinuingInAnotherProcess flag is never reset since it was introduced in
        r243767. This leads to leaking Navigation objects in the UIProcess when reusing a previously
        suspended process because such process will no longer send the DidDestroyNavigation IPC.

        It turns out that resetting the flags causes API tests such as ProcessSwap.QuickBackForwardNavigationWithPSON
        to ASSERT. This is because when the UIProcess quickly navigate back and forth without waiting for policy
        decisions, we may end up getting the policy decision for a particular navigation *after* we've sent the
        DidDestroyNavigation.

        As a result, this patch reverts r243767 and fixes in the assertion in http/tests/adClickAttribution/store-ad-click-attribution.html
        another way. We initially assumed that the logic in WebPageProxy::didDestroyNavigation() was failing to
        ignore the DidDestroyNavigation from the previous process after a swap due to a race, maybe because it was
        sometimes received too late and m_provisionalPage was already cleared. However, this would not make sense
        since the test is crashing consistently and the page would no longer be able to receive IPC from the
        previous process *after* we've committed the provisional process/page.

        The real issue was that the DidDestroyNavigation IPC was received *before* we could construct the
        provisional page, which is why the logic in WebPageProxy::didDestroyNavigation() was failing to ignore
        the bad IPC. In WebPageProxy::receivedNavigationPolicyDecision(), we were calling receivedPolicyDecision()
        (which would send the DidReceivePolicyDecision to the previous WebProcess) and then continueNavigationInNewProcess()
        in order to construct the provisional page. I personally did not expect we could receive IPC between the
        calls to receivedNavigationPolicyDecision() and receivedPolicyDecision(), since we are not yielding and since
        the DidReceivePolicyDecision IPC is asynchronous. However, this is exactly what was happening in the context
        of this test. The reason is that the DidReceivePolicyDecision IPC was getting wrapped in a synchronous message
        and sent as synchronous message due to the Connection::m_inDispatchMessageMarkedToUseFullySynchronousModeForTesting
        flag which seems to get set in the test due to some EventSender IPC. I believe this is because the test uses
        EventSender to do a click on a link which triggers the navigation.

        To address the issue, I now call receivedNavigationPolicyDecision() *after* continueNavigationInNewProcess()
        to make sure that we always start the provisional load in the new process before we tell the previous process
        to stop loading. This way, there is no way we get IPC from the previous process about the current navigation
        before we have a provisional page.

        Reviewed by Brent Fulgham.

        Several projects have post-processing build phases where exported
        headers are tweaked after they've been copied. This post-processing is
        performed via scripts called postprocess-headers.sh. For reasons
        related to XCBuild, we are now transitioning to a build process where
        the post-processing is performed at the same time as the
        exporting/copying. To support this process, add similar scripts named
        postprocess-header-rule, which are geared towards processing a single
        file at a time rather than all exported files at once. Also add a
        build rule that makes use of these scripts. These scripts and build
        rules are not used at the moment; they will come into use in an
        imminent patch.

        Note that I've named these postprocess-header-rule rather than
        postprocess-header-rule.sh. Scripts in Tools/Scripts do not have
        suffixes indicating how the tool is implemented. Scripts in
        per-project Scripts folders appear to be mixed regarding the use of
        suffixes. I'm opting here to follow the Tools/Scripts convention, with

        InjectedBundle parameters often need initialization function called before unarchiving

        Handle the case where the InjectedBundle parameters do not successfully decode because they contain
        an unexpected class from the embedding program. If this happens, try decoding the bundle parameters
        after the bundle initialiation function runs, which gives the embedding program the opportunity to
        register additional classes that are safe for serialization.

        Extend WKWebProcessPlugIn with a method that returns the names of any custom classes that need
        to be serialized by the InjectedBundle.

        Add prioritization of ad click conversions and cleaning of sent ad click conversions
        https://bugs.webkit.org/show_bug.cgi?id=196934
        <rdar://problem/49917773>

        Reviewed by Chris Dumez.

        In this description, by "pair" I mean { AdClickAttribution::Source, AdClickAttribution::Destination }.

        This patch adds handling of prioritization of conversions according to these rules:
        - If we have a matching unconverted attribution, convert it. This consumes the conversion.
        - If we have no previously converted attribution for this pair, just store.
        - If we have a previously converted attribution for this pair, replace it if the new one has higher priority.
        - If we had no matching unconverted attribution but do have a previously converted attribution for this
        pair, re-convert the previously converted attribution to make sure the highest priority gets set.

        This handling is in part done by dividing the previous m_adClickAttributionMap into 
        m_unconvertedAdClickAttributionMap and m_convertedAdClickAttributionMap, which now use a std::pair
        as key instead of a nested HashMap.

        This patch also changes AdClickAttributionManager::firePendingConversionRequests() so that it now
        removes attributions which have been sent out.

        Finally, AdClickAttributionManager::clear() no longer clears m_conversionBaseURLForTesting and
        m_isRunningTest since doing so caused test flakiness. It is now up to the test case that sets these
        members to also clear them when done.

        Most actions one can take with a _WKWebViewPrintFormatter involve

        Doing so while the Web Content process is awaiting a reply to a deferred-reply
        synchronous message (like, say, an alert()) results in an app-destroying deadlock.
        Instead of that, return a nil _WKWebViewPrintFormatter, indicating to the client

        The above isn't sufficient, though, because a sync message could arrive and
        be handled between creation and use of the _WKWebViewPrintFormatter.
        So, we also bail with a zero page count and null CGPDFDocument immediately
        before we would send a sync message to the Web Content process. Clients
        handle this less gracefully (e.g. showing a zero page PDF), but it is
        very rare compared to the above case.

        We hit the release assertion due to the following sequence of events:
        - Dispatch a queued event (in this case, a scroll event)
        - Invoke the scroll event listener, which modifies layout in some way
        - This scrolls an overflow scrollable container under the scope of layout
        - Overflow scrolling then calls didChangeSelection and triggers an editor state update, which updates layout

        In the case where the selection is in the main frame, we bail early due to the check for recursive layout (i.e.
        frameView->layoutContext().isInRenderTreeLayout()). However, in the case where the selection is inside a
        subframe, we end up skipping past this check, since the subframe's FrameView isn't currently laying out, and so
        we end up hitting the release assertion underneath the early return.

        To fix this, simply defer editor state updates due to overflow scrolling until the next remote layer tree commit
        instead of computing and sending the information immediately. While this only defers editor state updates during
        overflow scrolling, <rdar://problem/47258878> tracks making editor state updates deferred in the general case.

        While dispatching layout milestones (mixture of layout and painting items), the associated drawing areas should only capture the painting related milestones.
        These captured milestones get dispatched later in the commit handler to ensure that they are not forwarded prematurely.
        However the truly layout related milestones (e.g. DidFirstVisuallyNonEmptyLayout) should be dispatched right away with no delay.

        This patch schedules a conversion request with appropriate data going to the
        click source as a result of an ad click conversion.

        WebKit::AdClickAttributionManager makes use of existing WebKit::PingLoad
        infrastructure to make the request. This will probably be reworked into a
        dedicated load class further on.

        New test infrastructure allows for an override of both the conversion URL

        even though it is from a previous navigation. For this reason, the ProvisionalPageProxy should ignore all

        Reviewed by Darin Adler.

        On some websites, hidden editable elements are very frequently focused upon user interaction. Currently, this
        causes the software keyboard to pop in and out unexpectedly; luckily, these same sites also apply
        inputmode="none" to the hidden editable element, which ought to ensure that the software keyboard doesn't appear
        when the element is focused.

        However, since we disabled support for inputmode="none" in r240497, the software keyboard is no longer
        suppressed, and becomes a big nuissance. r240497 removed support for this feature because, when using a hardware
        keyboard, pressing the globe key no longer showed UI for switching languages. However, support for inputmode
        none makes a much larger impact when a software keyboard is used (since the entire software keyboard animates in
        and out), whereas a hardware keyboard only displays an input accessory view. For this reason, we can mitigate
        this bug without reintroducing <rdar://problem/47406553> by re-enabling inputmode="none", but only when a
        hardware keyboard is not attached.

        When the network process gets terminated by the client, the NetworkProcessProxy object (and thus its DownloadProxyMap member) get
        destroyed right away, before we get a call to didClose(IPC::Connection&). As a result, if there are ongoing downloads at the time
        of the termination, we will hit the assertion above. To address the issue, update the NetworkProcessProxy destructor to invalidate

        Adds support for using WebsitePolicies to determine whether to enable the MediaSource API.

        * Shared/WebPreferences.yaml:

        Disengage the mediaSourceEnabled internal preference from the corresponding WebCore setting; to ensure that
        setting the preference to `true` still results in enabling the MediaSource API, we instead make it such that
        turning on mediaSourceEnabled causes WebsitePolicies to set its WebsiteMediaSourcePolicy to Enable.

        In the future, we should deprecate and remove this preference, in favor of simply setting preferred
        compatibility mode on WKWebpagePreferences.

        (WebKit::WebsitePoliciesData::applyToDocumentLoader):

        Update the document loader with the given media source policy. There are two possibilities when applying the set
        of policies to the document loader; either the document loader is already attached to a Frame, or the document
        loader is yet to be attached to a Frame.

        In the first case, we update Frame's settings on the spot, by calling the new applyPoliciesToSettings helper
        method. In the second scenario, we stash the policy state on DocumentLoader; when the DocumentLoader is attached
        to a Frame, we'll then update the Frame's settings using DocumentLoader's policy.

        Regression(r240562) Audio sometimes keeps playing in previous process after a process-swap
        https://bugs.webkit.org/show_bug.cgi?id=196774
        <rdar://problem/49460572>

        Reviewed by Alex Christensen.

        r240562 added logic to prevent flashing on navigation. When we receive the DidFailToSuspendAfterProcessSwap
        IPC from the previous process, we would delay closing the WebPage in that process until EnterAcceleratedCompositingMode
        IPC is received from the new process. The issue is that this was racy as we would receive the EnterAcceleratedCompositingMode
        IPC from the new process *before* receiving the DidFailToSuspendAfterProcessSwap IPC from the previous process, which which
        case we would fail to close the WebPage and audio could keep playing.

        To address the issue, the WebPageProxy keeps track of its last suspended page and notifies it whenever it receives the
        EnterAcceleratedCompositingMode IPC. If the suspended page already received the DidFailToSuspendAfterProcessSwap IPC, it
        will close the page. Otherwise, it will set a boolean data member indicating that we should not delay page closing when
        the DidFailToSuspendAfterProcessSwap is eventually received.

        RemoteObjectRegistry message receiver should be removed when WebPage::close is called instead of waiting until dealloc

        This is a similar problem to the one I fixed in r241306 so I piggy-backed on the same test.
        When you do a cross site navigation but the previous page is in a suspended process then you navigate back,
        you can get two WebPage objects in the same process with the same IDs.  WebPage::close has been called
        on the old one which is supposed to make it so all the message receivers associated with it have been removed
        so we don't have any loss of communication, but we missed the RemoteObjectRegistry messages, which are owned
        by the ObjC bundle object wrapping the WebPage (which can keep it alive if a strong reference to it is held).
        To fix the assertion that happens in this case and the resulting communication breakage, teach the WebPage about
        these messages so it can tear down the message receiver with the others it removes at close time.

        So called pixel requests have traditionally been used to send ad click
        attribution data to click sources. The privacy implications of such

        To allow for a smooth transition to more privacy-friendly ad click
        attribution, we should allow servers to make a redirect to
        https://click-source.example/.well-known/ad-click-attribution/ to
        trigger a so called conversion.

        This patch checks for the well-known location in the path component of

        Our logic to decide if we should construct a SuspendedPageProxy on process-swap was assuming
        a SuspendedPageProxy is only useful for PageCache and would therefore not create one if PageCache
        is disabled or if there is no associated WebBackForwardListItem. However, constructing a
        SuspendedPageProxy is also useful to prevent flashing when process-swapping as we need to keep
        displaying the layer of the previous process until there is something meaningful to show in the
        new process.

        This patch makes it so that we now construct a SuspendedPageProxy on process-swap, even if
        PageCache is disabled or if there is no associated WebBackForwardListItem. The process in
        question will not be useful for PageCache but it will avoid flashing. The SuspendedPageProxy's
        process may also get used for future navigations to the same site (as demonstrated by the
        API test) which is beneficial for performance.

        [iOS] Do not allow starting selection drags when selection views are not visible
        https://bugs.webkit.org/show_bug.cgi?id=196686
        <rdar://problem/49399192>

        Reviewed by Tim Horton.

        Currently, on iOS, it's possible to start dragging selected text in a web view even if the selection itself is
        not visible. This can happen if the user selects some text, focuses a native text field, and then long presses
        the previously selected text. This is because the text is still selected in the document since we don't clear
        the selection when resigning first responder on iOS, despite the fact that the native selection view is no
        longer present.

        To fix this, we add plumbing to specify the set of allowed drag source actions when requesting drag start; this
        set of allowed drag source actions only includes DragSourceActionSelection if the selection view can be visible
        (i.e. the content view is first responder, and isn't suppressing text interactions). We then update WebPage's
        allowed drag source actions with this given set of actions, while sending "dragstart" to the page.

        Web Automation: clean up some WebAutomationSession methods to use modern async IPC
        https://bugs.webkit.org/show_bug.cgi?id=196168

        Reviewed by Devin Rousso.

        Modern WebKit IPC is capable of providing completion handlers and can track callback IDs.
        So, most messages between WebAutomationSession and its proxy can use this facility and stop
        keeping track of callback IDs manually. This makes most code easier to read on both the
        sender and receiver side.

        There are two cases that could not be converted:
        - For evaluateJavaScript, we cannot use async IPC because WebAutomationSession expects to
        be able to cancel all pending replies when a page navigates away, the web process crashes,
        or when handling an alert.
        - For takeScreenshot, there is not currently support in the modern async IPC code paths for
        sending the result back. ShareableBitmap and friends lack a modern decoder implementation.

        https://bugs.webkit.org/show_bug.cgi?id=195584

        Reviewed by Zalan Bujtas.

        Push data to the scrolling tree about whether an overflow:scroll scroll was programmatic, by having
        RenderLayer::scrollToOffset() call into AsyncScrollingCoordinator::requestScrollPositionUpdate(),
        just as we do for frames.

        AsyncScrollingCoordinator::requestScrollPositionUpdate() is generalized to take any ScrollableArea.

        Fix an assumption in the ScrollingTree that we only care about programmatic scrolls on the root node.
        ScrollingTree::commitTreeState() no longer sets isHandlingProgrammaticScroll; instead,
        callers of ScrollingTreeScrollingNode::scrollTo() pass a ScrollType. Commit functions pass
        ScrollType::Programmatic when handling RequestedScrollPosition changes as necessary.

        Programmatic scrolls need to get to the scrolling tree in the UI process so that we update
        the tree's notion of scroll position, and trigger actual UIScrollView scrolls (layers may have
        already been put in the right locations, but the UI process needs to know that a scroll happened).
        However, we need to prevent notifications from programmatic scrolls getting back to the
        web process, because this causes jumpiness. This is done via an early return in

        Changing default website policies shouldn't change default website policies in subsequent navigations
        https://bugs.webkit.org/show_bug.cgi?id=196562
        <rdar://problem/49573377>

        Reviewed by Tim Horton.

        Currently, changing the default WKWebpagePreferences object when deciding navigation policy causes the set of
        default policies to change in subsequent navigations. Among other things, this prevents clients from passing
        a modified version of the default website policies into the decision handler without impacting future
        navigations. To fix this, teach API::WebsitePolicies to make a copy of itself, and then use this to pass a copy
        of the default website policies to the navigation delegate when deciding navigation policies.

        to reflect whether the focused element contains selectable text. This is what UIKit wants to know when it queries
        -isEditable. Now that we no longer blur the focused element on iPad when the popover is dismissed and keep the
        peripheral until there is a focus change we need to ensure that we give the correct answer to UIKit on view
        editability. Otherwise, UIKit thinks it needs to update the text selection state when a popup button is tapped
        again (as part of its gesture recognizer logic) and this causes an assertion failure in UIKit after it calls back
        into us to ask for selection details, which we correctly respond with the equivalent of "we have none" and is
        not the answer UIKit expects since we told it we are editable. (Currently we manage to get away with telling UIKit
        we are always editable because it is not possible to perform a selection operation when we have a popover open.
        Closing the popover blurs the element, setting -isEditable to NO and deallocates the peripheral avoiding this issue).

        r243726 made an incorrect assumption that all callers of -decidePolicyForNavigationAction:decisionHandler: and
        -decidePolicyForNavigationAction:userInfo:decisionHandler: must be instances of _WKWebsitePolicies, as opposed
        to the new WKWebpagePreferences. However, it's possible for clients (in this case, Safari) to already generate
        and pass in an instance of WKWebpagePreferences by bridging the C API opaque ref (WKWebsitePoliciesRef) into the
        Objective-C object (which is now WKWebpagePreferences, after my change).

        To maintain binary compatibility of trunk WebKit against prior versions of Safari, we need to handle both
        WKWebpagePreferences and the soon-to-be-deprecated _WKWebsitePolicies in the navigation action policy decision
        handler.

        The crash is happening because WebPage::focusedElementDidChangeInputMode assumes that the document's focused
        element must be the same as m_focusedElement in WebPage. However, this is not the case, since m_focusedElement
        is only set for certain types of elements that require user input (e.g. text fields, editable content, select
        menus, etc.). The function then attempts to dereference m_focusedElement, which may be null if the document's
        focused element doesn't fall into one of the aforementioned categories.

        To fix this, bail if the element that is changing inputmode is not equal to the WebPage's current focused
        element. See below for more details.

        The move of Resource Load Statistics to the network process requires that it
        calls the UI process when clearing website data (previously the other way
        around). This patch achieves that.

        Specifically, NetworkProcess::deleteWebsiteDataForRegistrableDomains() now
        filters its WebsiteDataTypes down to just the ones applicable for the UI
        process and then calls DeleteWebsiteDataInUIProcessForRegistrableDomains over
        IPC.

        NetworkProcessProxy::deleteWebsiteDataInUIProcessForRegistrableDomains() on
        the UI process side makes use of the re-introduced
        WebsiteDataStore::fetchDataForRegistrableDomains() function to get the relevant
        data records and call WebsiteDataStore::removeData(). The re-introduced
        WebsiteDataStore::fetchDataForRegistrableDomains() was removed as dead code in

        Reviewed by Carlos Garcia Campos.

        Currently it's possible for webkit_web_resource_get_data_finish() to return NULL without
        setting the error parameter. This is illegal because it is an API guarantee (and a GObject
        convention) that if an error parameter exists, it should be set whenever a function call
        returns NULL. Epiphany correctly dereferences the error in this case without checking if it
        is NULL, because it knows it does not have to, and crashes. Fix this. We'll return a byte
        array of length 1 containing a NUL character. This isn't great, but there's not really any
        better solution without deprecating the API or returning an error code to indicate an empty
        resource, and it at least fixes the Epiphany crash.

        This does not fix bug #186276, in which this function incorrectly returns no data when it
        ought to. But that is a different bug. Now, at least we won't crash when no data is
        available.

        Need a way to include WebKitAdditions code in WebKit API headers
        https://bugs.webkit.org/show_bug.cgi?id=196173

        Reviewed by Tim Horton.

        Introduce a mechanism that allows us to insert code from WebKitAdditions into public or private SDK headers
        using `#import`s of the form:

        ```
        #if USE(APPLE_INTERNAL_SDK)
        #import <WebKitAdditions/WKWebViewConfigurationAdditions.h>
        #endif
        ```

        The resulting header in the built products directory will contain the contents of the imported file inserted in
        place of the `#if USE(APPLE_INTERNAL_SDK) … #endif` block; however, when building with the Apple internal SDK,
        the additions header content will be imported by the usual means.

        * mac/postprocess-framework-headers.sh:
        * mac/replace-webkit-additions-includes.py: Added.

        Add a step when post-processing framework headers to replace instances of `#if USE(APPLE_INTERNAL_SDK) … #endif`
        with the text content of the additions files. The replacement script first searches in the built products
        directory for the matching additions file, and falls back to the SDK if no matching file is found. If neither
        are present (e.g. a build using the public SDK), then the block is simply replaced by the empty string.

        <rdar://problem/49127581>

        Reviewed by Alex Christensen.

        When, an AuxiliaryProcess receives the AuxiliaryProcess::Terminate IPC, it calls stopRunLoop()
        to exit. WebProcess overrides AuxiliaryProcess::stopRunLoop() to call exit(0) on the main
        thread. Other auxiliary processes such as the NetworkProcess would end up calling
        platformStopRunLoop(). On iOS and iOSMac, platformStopRunLoop() calls XPCServiceExit(), which
        makes sense since auxiliary processes run their run loop by calling xpc_main(). However, on
        macOS, platformStopRunLoop() was calling RunLoop::main().stop() to exit instead, which was
        unreliable as demonstrated by the test app attached to the radar.

        Updating platformStopRunLoop() to call XPCServiceExit() on macOS fixes the problem and I now
        see the NetworkProcess exiting reliably there. This is the approach I have chosen in this
        patch since it appears to be reliable and it makes the code consistent on all Cocoa platforms.

        Before performing any logging, the NetworkProcess checks to see if
        it's performing an operation associated with a private (ephemeral)
        browsing session. If so, it skips the logging. However, networking
        layers below the NetworkProcess don't know about private browsing, so
        they would still perform their own logging. CFNetwork now has a flag

        The root cause is that DrawingAreaProxyCoordinatedGraphics::isInAcceleratedCompositingMode checks both of alwaysUseCompositing() and !m_layerTreeContext.isEmpty().
        alwaysUseCompositing() refers preferences, which is written by the application (UIProcess).
        On the other hand, m_layerTreeContext is changed when it receives enterAcceleratedCompositingMode/exitAcceleratedCompositingMode from WebProcess.

        It results when we set forceCompositingMode and acceleratedCompositingEnabled to true, WebProcess and UIProcess is out of sync until WebProcess sends enterAcceleratedCompositingMode message.
        In such situation, WebProcess sends incorporateUpdate to UIProcess because WebProcess is in non-AC mode, but isInAcceleratedCompositingMode becomes true in UIProcess side.

        a nice central place to capture layout milestones. However, it will
        only log notifications that are being sent to clients. It does not
        indicate all milestones that have occurred. That is, it does not

        Enable building with Thin LTO in Production when using Xcode 10.2 or
        later. This change results in a 1.45% progression in PLT5. Full
        Production build times increase about 2-3%. Incremental build times
        are more severely affected, and so LTO is not enabled for local
        engineering builds.

        LTO is enabled only on macOS for now, until rdar://problem/49013399,
        which affects ARM builds, is fixed.

        To change the LTO setting when building locally:

        - If building with `make`, specify WK_LTO_MODE={none,thin,full} on the
          command line.
        - If building with `build-webkit`, specify --lto-mode={none,thin,full}
          on the command line.
        - If building with `build-root`, specify --lto={none,thin,full} on the
          command line.
        - If building with Xcode, create a LocalOverrides.xcconfig file at the
          top level of your repository directory (if needed) and define
          WK_LTO_MODE to full, thin, or none.

        Implement WebProcess freezer opt-in completely on WebContent process side, we do not need
        to involve the UIProcess with this and rely on IPC which may be fragile.

        In the future, we may want to set freezable state from the UIProcess when the API supports
        it. We can move the logic to be fully on the UIProcess side then. In the mean time, it is
        likely best not to rely on IPC and process coordination for this.

        Prewarmed processes should be usable with any website data store
        https://bugs.webkit.org/show_bug.cgi?id=196104

        Reviewed by Alex Christensen.

        Split WebsiteDataStore-specific data out of WebProcessCreationParameters and into a new
        WebProcessDataStoreParameters struct so that we do not need a WebsiteDataStore in order
        to lauch and initialize a WebProcess. When the process finally gets used and we thus
        know which WebsiteDataStore they will be used for, we send the WebProcessDataStoreParameters
        to the process to that it can do its data store-specific initialization.

        This allows prewarmed processes not not have a WebsiteDataStore assocated with them. They
        can then be used for any WebsiteDataStore when we need them.

        This is also used by our dummy WebProcessProxy since it does not have a backing process and
        thus has no associated WebsiteDataStore.

        Certain WebProcesses should opt-out of the freezer.
        <rdar://problem/42846139> and https://bugs.webkit.org/show_bug.cgi?id=196062

        Reviewed by Andy Estes.

        WebProcesses should opt-in and opt-out of the freezer as is appropriate.
        By default a WebProcess is freezer eligible.
        If any of the following become true then it should become ineligible:
        - The WebProcess is a pre-warmed process.
        - The WebProcess is in the process cache.
        - The WebProcess is not actively hosting any web pages (e.g. it only has suspending web pages)

        The most complicated part of the above is guaranteeing that any operation that changes
        the active pages hosted by the process causes a recalculation of the freezer opt-in state.

        To do that this replaces the basic WebPageProxyMap with a custom class.

        Cache API and IDB space usages should be initialized on first quota check
        https://bugs.webkit.org/show_bug.cgi?id=195707

        Reviewed by Chris Dumez.

        When the quota manager is created, make sure it delays quota check decisions until IDB and Cache API quota users are initialized.
        For IDB, the creation is synchronous but it may not be synchronous for Cache API.
        For that purpose, add a temporary quota user that will stay uninitialized until these two quota users are added.
        Once added, the temporary quota user is removed.
        The addition of the real users is made asynchronously as this is triggered by the creation of one of the two quota users.

        In the case of a Cache API caches being cleared, make sure to reset the size to zero and to redo the quota user initialization dance.

        We could re-implement such that -setAccessoryViewCustomButtonTitle: stores the title and calls
        -_updateAccessory, but that has the disadvantage of increasing the memory footprint of WKContentView
        for the stored title and that seems worse than centralizing the logic in _updateAccessory. So,
        let's not fix this FIXME. Now that we are removing the FIXME, change to use an early return style.
        (-[WKContentView _hideKeyboard]): Micro optimization; only call _updateAccessory if we have
        a form accessory view. This method is called everytime we load a page (more precisely when we

        Resource Load Statistics (experimental): Clear non-cookie website data for sites that have been navigated to, with link decoration, by a prevalent resource
        https://bugs.webkit.org/show_bug.cgi?id=195923
        <rdar://problem/49001272>

        Reviewed by Alex Christensen.

        Cross-site trackers abuse link query parameters to transport user identifiers and then store
        them in first-party storage space. To address this, we've done three things:
        - r236448 capped all persistent client-side cookies to seven days of storage.
        - r242288 further capped persistent client-side cookies for navigations with link decoration from prevalent resources.
        - r242603 added logging of navigations with link decoration from prevalent resources.

        This patch introduces an experimental feature that removes non-cookie website data for sites
        that have been navigated to, with link decoration, by a prevalent resource.

        To achieve this, resource domains to remove website data for are now marked with an enum called
        WebsiteDataToRemove with values All, AllButHttpOnlyCookies, AllButCookies. As resources are
        iterated, they are marked for either of these values and the new function
        ResourceLoadStatisticsMemoryStore::shouldRemoveAllButCookiesFor() leads to the marking with
        WebsiteDataToRemove::AllButCookies.

        Then NetworkProcess::deleteWebsiteDataForRegistrableDomains() looks at this setting and removes
        website data accordingly.

        The thinking behind this is that the lifetime cap applied in r236448 and r242288 take care of
        script writable cookies, and this patch takes care of all other script writable storage.

        The infrastructure to handle user interaction expiration is now parameterized so that multiple
        expiries can be applied. In this particular case, seven days of browser use.

        Spew: Unhandled web process message 'VisitedLinkTableController:VisitedLinkStateChanged'
        https://bugs.webkit.org/show_bug.cgi?id=194787
        <rdar://problem/48175520>

        Reviewed by Geoff Garen.

        The unhandled 'VisitedLinkTableController:VisitedLinkStateChanged' message logging happens
        when IPC is sent to a WebProcess which does not have a VisitedLinkTableController with the
        given identifier. VisitedLinkTableController are kept alive by the WebPage in the WebProcess
        side so this indicates that there is no WebPage using this VisitedLinkTableController anymore.

        In the UIProcess side, our tracking of who is using which VisitedLinkStore was very poor.
        WebPageProxy objects would ask their process to register itself with the page's visitedLinkStore
        as soon as the WebPage object has been created on the WebProcess side. This part was fine.
        However, unregistration from the visitedLinkStores would only happen when either the
        visitedLinkStore would get destroyed or when the WebProcess would shutdown. This means that
        WebProcess could stay registered with a visitedLinkStore even after the page that was using it
        has been closed, which would lead to such logging.

        To address the issue, the WebProcessProxy now keeps track for which pages are using which
        visitedLinkStore. When a visitedLinkStore is used by a page for the first time, the
        WebProcessProxy will register itself with the visitedLinkStore. Similarly, when the last page
        using a given visitedLinkStore is closed, the process unregisters itself from the
        visitedLinkStore, thus avoiding the bug.

        I also simplified a lot the logic for having a page telling the WebProcessProxy it started
        using a visitedLinkStore. Previously, it would have to wait until the process is done launching
        before notifying the WebProcessProxy. Now, the WebPageProxy merely tells the WebProcessProxy
        that it is starting to use a visitedLinkStore as soon as it sent the CreateWebPage IPC to the
        WebProcess (no matter if the process is still launching or not). At this point, the
        WebProcessProxy registers the page as a user of the visitedLinkStore and takes care of waiting
        until it is done launching before registering itself with the visitedLinkStore.

        injected bundle. Part of the "reset" message sets the external hosts that we're allowed
        to load. If there is no WebProcess yet when WKPagePostMessageToInjectedBundle() is called,
        then this message does not get sent and the allowed hosts do not get set, causing this
        test failure.

        To address the issue, make sure we launch the initial process if necessary when
        WebPageProxy::postMessageToInjectedBundle() is called, in order to maintain backward
        compatibility.

        Fixes a usability annoyance when using a hardware keyboard; focus is not preserved when switching between tabs.
        Do not unconditionally tell the WebProcess to blur the currently focused element when the content view (WKContentView)
        resigns first responder. Instead only tell it to blur when the content view is resigning because either the
        accessory view was dismissed (Done button was pressed) or the keyboard was dismissed (the hide keyboard button
        was pressed).

        (-[WKContentView resignFirstResponderForWebView]): Only tell WebKit to blur the focused element if we are
        resigning because the accessory view is being dismissed or the keyboard was hidden. We continue to do all
        other steps when resigning, including hiding the keyboard. Note that by not telling WebKit to blur the
        focused element we let it's focus controller manage the focused element with respect to the current
        page activation state (i.e. whether the content view is first responder or not). When the content view
        becomes the first responder then WebKit's focus controller will be told that the page has become activated
        and will tell the UIProcess to focus the currently focused element, which will bring up the keyboard.
        (-[WKContentView accessoryDone]): Update state so we know that a subsequent call to resign first responder
        was due to the accessory view being dismissed.

        Spew: Unhandled web process message 'VisitedLinkTableController:VisitedLinkStateChanged'
        https://bugs.webkit.org/show_bug.cgi?id=194787
        <rdar://problem/48175520>

        Reviewed by Geoffrey Garen.

        The unhandled 'VisitedLinkTableController:VisitedLinkStateChanged' message logging happens
        when IPC is sent to a WebProcess which does not have a VisitedLinkTableController with the
        given identifier. VisitedLinkTableController are kept alive by the WebPage in the WebProcess
        side so this indicates that there is no WebPage using this VisitedLinkTableController anymore.

        In the UIProcess side, our tracking of who is using which VisitedLinkStore was very poor.
        WebPageProxy objects would ask their process to register itself with the page's visitedLinkStore
        as soon as the WebPage object has been created on the WebProcess side. This part was fine.
        However, unregistration from the visitedLinkStores would only happen when either the
        visitedLinkStore would get destroyed or when the WebProcess would shutdown. This means that
        WebProcess could stay registered with a visitedLinkStore even after the page that was using it
        has been closed, which would lead to such logging.

        To address the issue, the WebProcessProxy now keeps track for which pages are using which
        visitedLinkStore. When a visitedLinkStore is used by a page for the first time, the
        WebProcessProxy will register itself with the visitedLinkStore. Similarly, when the last page
        using a given visitedLinkStore is closed, the process unregisters itself from the
        visitedLinkStore, thus avoiding the bug.

        I also simplified a lot the logic for having a page telling the WebProcessProxy it started
        using a visitedLinkStore. Previously, it would have to wait until the process is done launching
        before notifying the WebProcessProxy. Now, the WebPageProxy merely tells the WebProcessProxy
        that it is starting to use a visitedLinkStore as soon as it sent the CreateWebPage IPC to the
        WebProcess (no matter if the process is still launching or not). At this point, the
        WebProcessProxy registers the page as a user of the visitedLinkStore and takes care of waiting
        until it is done launching before registering itself with the visitedLinkStore.

        On certain websites, focus is moved away from an editable element while maintaining a selection inside the

        suppression heuristics, which suppress text selection gestures and overlays inside focused hidden editable
        elements. To fix this, we refactor our text interaction suppression heuristics, such that they are not dependent
        on an editable element being focused. See changes below for more details.

        selection when focusing editable elements, zooming is deferred until the next complete EditorState update
        arrives in the UI process so we don't need to worry about beginning to suppress text interactions prior to this
        initial editor state update.

        (-[WKContentView _elementDidBlur]):
        (-[WKContentView _updateSelectionAssistantSuppressionState]):

        Add a helper method that updates text selection suppression state using the current EditorState.

        (-[WKContentView _selectionChanged]):
        (-[WKContentView _updateChangedSelection:]):

        Always update text suppression state when receiving an EditorState, instead of only doing so when processing a
        text selection gesture.

        (-[WKContentView _startSuppressingSelectionAssistantForReason:]):

        Renamed from _beginSuppressingSelectionAssistantForReason:, to better match "start/end" terminology of
        _endSuppressingSelectionAssistantForReason:.

        Delay WebProcess launch until a load is triggered in a Web view
        https://bugs.webkit.org/show_bug.cgi?id=195758

        This is achieved by constructing WebPageProxy objects with a WebProcessProxy that is in
        terminated state (because it never launched its process). This is convenient because
        it is a state that the WebPageProxy supports, which normally happened by the WebProcess
        crashes. When trying to do a load, we were already checking if the WebPageProxy's process
        was running (via an isValid() check) and we would re-launch the WebProcess if necessary
        by calling reattachToWebProcess(). For clarity, given that this state is no longer
        indicating that the WebProcess crashed, I renamed isValid() to hasRunningProcess() and
        reattachToWebProcess() to launchProcess().

        The reason delaying the WebProcess launch until the first load is useful is because it
        allows us to leverage the WebProcessCache given that we now know which registrable
        domain is going to be loaded in the process.

        This is a progression from a power usage standpoint. When it comes to page load time,
        it would be a progression if we found a suitable process in the cache. I do not expect
        a performance hit when no process is found in the cache because of process prewarming.

        [iOS] No DOM keypress event emitted for cursor key commands when non-editable element is focused
        https://bugs.webkit.org/show_bug.cgi?id=195626
        <rdar://problem/48810626>

        Reviewed by Wenson Hsieh.

        Following the UIKit fix <rdar://problem/47333786> WebKit will be asked whether it can perform some
        more actions, including cursor movements and more editing actions. All such actions are only applicable
        to editable elements. By responding NO to UIKit for such actions when we are not in an editable element
        we avoid the need to do such bookkeeping ourselves as UIKit will forward our response back to us
        on return from -handleKeyTextCommandForCurrentEvent, called from -[WKContentView _interpretKeyEvent].
        WebKit is then in a position to try to handle the event or in the case of all standard text editing
        key commands at the time of writing (e.g. Control + a) tell WebCore that it did not handle the event

        [iOS] Software keyboard never appears when editing on some websites
        https://bugs.webkit.org/show_bug.cgi?id=195824
        <rdar://problem/48020610>

        Reviewed by Ryosuke Niwa.

        In the scenario where an element has already been programmatically focused but the UI process isn't showing an
        input view for it, there are a couple of different ways in which an input view may still be shown for that
        element:

        1. If the page attempts to programmatically focus the element, we'll invoke elementDidRefocus to recompute
        information about the focused element and propagate it to the UI process. By default, if programmatic focus was
        triggered under the scope of user interaction, we'll allow the input view to appear.

        2. In the case where page does not attempt to programmatically focus the element but a click is dispatched,
        there is logic in WebPage::completeSyntheticClick to send information about the already-focused element.

        On the web page relevant to this bug, focus is programmatically moved to hidden contenteditable areas upon page
        load, and touchstart is also prevented; furthermore, the page does not attempt to programmatically refocus the
        hidden editable area upon receiving touchstart. This means that the user will never be able to bring up the
        keyboard, since the editable area is already programmatically focused and subsequent attempts to tap in the
        page do nothing, because the page has already focused the hidden editable area (with the expectation that the
        software keyboard should already be present).

        To fix this, we bring some of the same logic in completeSyntheticClick over to dispatchTouchEvent, by sending
        focused element information to the UI process if the focused element did not change over the course of
        dispatching the touch event. Similar code was introduced in r167774 to fix the same type of issue (i.e.
        inability to bring up the software keyboard), but this was later reverted in r188405 due to causing bugs such as
        <rdar://problem/22204108>, wherein this logic to bring up the keyboard in dispatchTouchEvent would scroll and
        zoom the page, such that the click event fired after touchend would be dispatched in the wrong location and (in
        the case of <rdar://problem/22204108>) caused the focused element to immediately blur again.

        To mitigate this issue, we add the additional constraint that we only send focused element info in the case
        where the touch won't also generate a click later down the road, by requiring that the dispatched event was
        handled by the page (i.e. prevented).

        REGRESSION (r242801): [iOS] preventDefault() on touchstart in a subframe does not prevent focusing the subframe
        https://bugs.webkit.org/show_bug.cgi?id=195749
        <rdar://problem/48892367>

        Reviewed by Tim Horton.

        r242801 added logic to fetch interaction information at the touch location upon touch start. However this,
        combined with an existing behavior where the process of computing InteractionInformationAtPosition in WebPage
        moves focus into the frame of the hit-tested node below the touch location, means that we'll always trigger a
        blur event on the window and move focus into the subframe when performing a touch inside a subframe, even if the
        page prevents default on touchstart.

        To fix this, add a "readonly" flag to InteractionInformationRequest, and only change focus when requesting
        position information in the case where the request is not readonly. For now, this readonly flag is false by
        default; in a future patch, we should identify the (hopefully few) places that rely on position information
        requests to move focus, explicitly turn this bit off in those places, and otherwise send readonly position
        information requests by default.

        Scrolling tree should reposition non-stacking order descendents of overflow:scroll.
        https://bugs.webkit.org/show_bug.cgi?id=195608

        Reviewed by Zalan Bujtas.

        Step 1: add scrolling tree positioning nodes classes (but don't create them yet).

        Add Scrolling{State,Tree}PositionedNode to track composited layers that have to be repositioned when
        an async overflow:scroll scrolls. There are two instances in which this is necessary, reflected by
        the values of ScrollPositioningBehavior:

        ScrollPositioningBehavior::Moves - a composited layer whose containing block chain includes an
            async overflow scroller, but whose composited (i.e. z-order) parent is outside of the overflow.
            When the overflow scrolls, this layer has to move along with the overflow.

        ScrollPositioningBehavior::Stationary - a composited layer whose containing block chain skips the
            overflow scroller, but whose compositing (z-order) parent is the scroller, or inside the scroller.
            This only applies to position:absolute, on, for example, an overflow:scroll ith opacity.

        PositionedNodes are modeled after Fixed/Sticky nodes, with a new type of layout constraint just called LayoutConstraints.
        
        This patch adds support for PositionedNodes in the scrolling trees, but RenderLayerCompositor::computeCoordinatedPositioningForLayer()
        is just a stub so the new node types aren't created yet.
        
        RenderLayerBacking stores a ScrollingNodeID for the positioning role (just like the other roles). Since the Positioning
        role is about position relative to ancestors, a node with both Positioning and FrameHosting or Scrolling roles treats
        the Positioning node as the parent of the other types. A node should never have both Positioning and ViewportConstrained roles.

        The TLDR of that bookkeeping is:
        - Whenever any uploads are in progress, take an assertion for both Networking and UI processes.
        - Whenever a particular WebProcess has an upload in progress, take an assertion for it.

        [iOS] Input view sometimes flickers when blurring and refocusing an element
        https://bugs.webkit.org/show_bug.cgi?id=195639
        <rdar://problem/48735337>

        Reviewed by Tim Horton.

        On iOS, if a focused element is blurred and immediately refocused in the scope of user interaction, we will end
        up reloading interaction state (input views, autocorrection contexts, etc.) in the UI process. On certain well-
        trafficked websites, this results in the input view and input accessory view flickering (or more egregiously,
        scrolling to re-reveal the focused element) when changing selection.

        To fix the issue, this patch refactors some focus management logic to suppress sending focused element updates
        to the UI process in the case where the same element is being blurred and immediately refocused. To do this, we
        track the most recently blurred element and bail when the recently blurred element is identical to the newly
        focused element. See below for more detail.

        (-[WKContentView _elementDidBlur]):

        Update the web process' notion of whether an input view is showing. Importantly, this accounts for decisions
        made by _WKUIDelegate. See below for more details.

        (isAssistableInputType): Deleted.

        Removed this helper function; this was only used in one place as a sanity check that the focused element's type
        is not none, right before attempting to show an input view. Instead, we can just check the focused element's
        type directly against InputType::None in the if statement of the early return.

        * UIProcess/ios/WebPageProxyIOS.mm:
        (WebKit::WebPageProxy::setIsShowingInputViewForFocusedElement):

        Add a hook to notify the web process when an input view is showing or not (see below for more detail).

        (WebKit::WebPage::didStartPageTransition):
        (WebKit::WebPage::elementDidRefocus):
        (WebKit::WebPage::shouldDispatchUpdateAfterFocusingElement const):

        Add a helper to determine whether we notify the UI process about a newly focused element. On macOS, this is true
        only when the new focused element is neither the currently focused element, nor the focused element that was
        just blurred. On iOS, we have an additional constraint that when the input view is not showing, we still need to
        notify the UI process, since the UI process might want to begin showing the keyboard for an element that has
        only been programmatically focused, for which we aren't currently showing the input view.

        (WebKit::WebPage::elementDidFocus):
        (WebKit::WebPage::elementDidBlur):

        Replace a couple of existing member variables in WebPage used for focus management:
        -   Replace m_hasPendingBlurNotification with m_recentlyBlurredElement, a RefPtr to the Element that is being
            blurred. Behavior here is the same as before (i.e. having a pending blur notification is equivalent to
            having recently blurred a focused element). However, this allows us to check newly focused elements against
            the recently blurred element in WebPage::elementDidFocus().
        -   Replace m_isFocusingElementDueToUserInteraction with m_isShowingInputViewForFocusedElement. The flag
            m_isFocusingElementDueToUserInteraction was originally added to fix <webkit.org/b/146735>, by ensuring that
            we don't send redundant ElementDidFocus (formerly, StartAssistingNode) messages to the UI process even when
            the keyboard is already up. In these simpler times, user interaction when focusing an element was equivalent
            to showing an input view for the focused element. However, in today's world, there are a variety of reasons
            why we might or might not show an input view for a given element (including, but not limited to activity
            state changes and decisions made by _WKInputDelegate). As such, it doesn't make sense to continue relying on
            m_isFocusingElementDueToUserInteraction in this early return. Instead, have the UI process propagate a
            message back to the web process, to let it know whether there is a keyboard showing, and use this flag
            instead.

        when the WebContent process is started, and when the backlight level is changed. On the WebContent side,
        the method getting the backlight level is swizzled to return the value sent from the UI process.

        [iOS] Implement a faster click detection that intercepts double-tap-to-zoom if possible

        <rdar://problem/48718396>

        Reviewed by Wenson Hsieh (with some help from Dan Bates).

        Adds a new algorithm, behind a flag FasterClicksEnabled, that can trigger a click
        event without waiting to see if a double tap will occur. It does this by examining
        the amount of zoom that would be triggered if it was a double tap, and if that value
        doesn't exceed a set threshold, commits to the click event instead.

        This is implemented by having the Web Process respond to the potential click with
        some geometry information. If the UI Process receives the information before the
        second tap in a double tap, it can decide to trigger a click.

        <rdar://problem/48733477>

        Reviewed by Alex Christensen.

        The crash was caused by the top-hit preloading logic in MobileSafari which creates a new Web view that is *related*
        to the previous one, restores the session state onto it and then triggers a load in this new Web view.

        Initially, the 2 Web views use the same process as they are related. However, if the new load's URL is cross-site
        with regards to the first view's URL, then we decide to process swap in the new view. This process swap makes
        sense from a security standpoint. However, when we commit the load in the new process and call
        suspendCurrentPageIfPossible() we end up in an unexpected state because we have a fromItem (due to the session
        state having been restored on the new view) but we haven't committed any load yet in this new view.

        To address the issue, suspendCurrentPageIfPossible() now returns early and does not attempt to suspend anything
        if we have not committed any load yet.

        [iOS] Block access to backboardd service
        https://bugs.webkit.org/show_bug.cgi?id=195484

        Reviewed by Brent Fulgham.

        This patch is addressing blocking the backboardd service "com.apple.backboard.hid.services". Getting the
        backlight level in the WebContent process will initiate a connection with this service. To be able to
        block the service, the backlight level is queried in the UI process and sent to the WebContent process
        when the WebContent process is started, and when the backlight level is changed. On the WebContent side,
        the method getting the backlight level is swizzled to return the value sent from the UI process.

        Reviewed by Chris Dumez.

        This bug tracks the work of removing the obsolete flag that had been used to optionally
        prevent display of the StorageAccess API prompt. We have since shipped the final version
        of this feature with an always-on prompt, and should have removed this runtime flag.

        No test changes because this has no change in behavior. Tests already assume the prompt
        behavior, and did not test turning the flag off.

        Reviewed by Geoffrey Garen.

        WebProcessCache should keep track of processes being added, while they are being
        checked for responsiveness. This is useful so that:
        - Requests to clear the cache also clear processes being added
        - Requests to remove a given process from the cache (either because it crashed
          or because it is being used for a history navigation) actually remove the
          process if it is still being checked for responsiveness.
        - The cached process eviction timer applies to such processes in case something
          goes wrong with the code and the pending request does not get processed.

        REGRESSION (r242551): Sporadic hangs when tapping to change selection on iOS
        https://bugs.webkit.org/show_bug.cgi?id=195475
        <rdar://problem/48721153>

        Reviewed by Chris Dumez.

        r242551 refactored synchronous autocorrection context requests to send an async IPC message and then use
        waitForAndDispatchImmediately, instead of calling sendSync. However, this exposes a couple of existing issues in
        the implementation of waitForAndDispatchImmediately that causes sporadic IPC deadlocks when changing selection.

        First, passing in InterruptWaitingIfSyncMessageArrives when synchronously waiting for an IPC message currently
        does not fulfill its intended behavior of interrupting waiting when a sync message arrives. This is because sync
        IPC messages, by default, may be dispatched while the receiver is waiting for a sync reply. This means that the
        logic in Connection::SyncMessageState::processIncomingMessage to dispatch an incoming sync message on the main
        thread will attempt to handle the incoming message by enqueueing it on the main thread, and then waking up the
        client runloop (i.e. signaling m_waitForSyncReplySemaphore). This works in the case of sendSync since the sync
        reply semaphore is used to block the main thread, but in the case of waitForAndDispatchImmediately, a different
        m_waitForMessageCondition is used instead, so SyncMessageState::processIncomingMessage will only enqueue the
        incoming sync message on the main thread, and not actually invoke it.

        To fix this first issue, observe that there is pre-existing logic to enqueue the incoming message and signal
        m_waitForMessageCondition in Connection::processIncomingMessage. This codepath is currently not taken because we
        end up bailing early in the call to SyncMessageState::processIncomingMessage. Instead, we can move this early
        return further down in the function, such that if there is an incoming sync message and we're waiting with the
        InterruptWaitingIfSyncMessageArrives option, we will correctly enqueue the incoming message, wake the runloop,
        and proceed to handle the incoming message.

        The second issue is more subtle; consider the scenario in which we send a sync message A from the web process to
        the UI process, and simultaneously, in the UI process, we schedule some work to be done on the main thread.
        Let's additionally suppose that this scheduled work will send an IPC message B to the web process and
        synchronously wait for a reply (in the case of this particular bug, this is the sync autocorrection context
        request). What happens upon receiving sync message A is that the IPC thread in the UI process will schedule A on
        the main thread; however, before the scheduled response to A is invoked, we will first invoke previously
        scheduled work that attempts to block synchronously until a message B is received. In summary:

        1. (Web process)    sends sync IPC message A to UI process.
        2. (UI process)     schedules some main runloop task that will block synchronously on IPC message B.
        3. (UI process)     receives sync IPC message A and schedules A on the main runloop.
        4. (UI process)     carry out the task scheduled in (2) and block on B.

        ...and then, the UI process and web process are now deadlocked because the UI process is waiting for B to
        arrive, but the web process can't send B because it's waiting for a reply for IPC message A! To fix this second
        deadlock, we first make an important observation: when using sendSync, we don't run into this problem because
        immediately before sending sync IPC, we will attempt to handle any incoming sync IPC messages that have been
        queued up. However, when calling waitForAndDispatchImmediately, we don't have this extra step, so a deadlock may
        occur in the manner described above. To fix this, we make waitForAndDispatchImmediately behave more like
        sendSync, by handling all incoming sync messages prior to blocking on an IPC response.

        Resource Load Statistics: Log first-party navigations with link decoration
        https://bugs.webkit.org/show_bug.cgi?id=195301
        <rdar://problem/48569971>

        Reviewed by Brent Fulgham.

        This patch adds a call to the network process' resource load statistics to
        log cross-site navigations with link decoration. The logging checks if the
        source of the navigation is a prevalent resource and if so, sets the
        appropriate flag for the destination.

        Reviewed by Žan Doberšek.

        Calling CompositingRunLoop::stopUpdates() on suspend is leaving the threaded compositor in an inconsistent
        state, failing to resume and stopping the updates forever. This is causing timeouts in WPE layout tests. Instead
        of calling stopUpdates(), a new suspend() is called, that stops the update timer, without changing the current

        [iOS] Frequent 1 second IPC deadlocks when showing a paste callout
        https://bugs.webkit.org/show_bug.cgi?id=195354
        <rdar://problem/48624675>

        Reviewed by Tim Horton.

        When triggering programmatic paste, we frequently hit deadlocks due to sync IPC going from the UI process to the
        web process and vice versa. What happens in this scenario is that prior to triggering programmatic paste, the
        page may try to move focus to a different element (e.g. a hidden editable area) before calling `execCommand`.
        This causes us to send an ElementDidFocus message to the UI process, followed by RequestDOMPasteAccess.

        However, upon receiving ElementDidFocus, we reload input views and (in the process) UIKit requests the
        autocorrection context, which we implement in WebKit using a sync message to the web process due to
        <rdar://problem/16207002> and its blocking bug <rdar://problem/48383001>. This means we'll end up in a state
        where both the UI process and web process are blocked on each other waiting for a sync IPC response, and the UI
        process is hung for a second until the IPC message times out.

        Ideally, we should fix this by addressing <rdar://problem/16207002>. However, this requires potentially large
        changes in UIKit (<rdar://problem/48383001>); for the time being, work around this deadlock by refactoring
        synchronous autocorrection context requests such that they can be resolved by an out-of-band IPC response
        (HandleAutocorrectionContext). Then prior to requesting DOM paste access, preemptively send a
        HandleAutocorrectionContext message to the UI process to unblock any pending synchronous autocorrection context
        requests.

        such links, which is permitted per the HTML spec.

        This change is only made on Cocoa platforms for now since no other ports
        expose an API on their navigation action to express whether the page intends
        to download the linked resource.

            Rename this to be in line with APINavigationAction's shouldPerformDownload()

            considering that 'forcing' the download isn't really an attribute inherent
            to the navigation, but a behavior implemented by the web page proxy.

        Reviewed by Chris Dumez.

        The ResourceLoadStatistics database plist is inefficient. It requires more memory use
        than it needs, and forces lots of looping and string comparisons to find information.

        This problem has already been solved in the form of relational databases. We use them
        elsewhere in WebKit, and should do so for this storage as well.

        This patch creates an optional SQLite database to handle ITP operations.

        1. It adds a new internal experimental feature flag to activate it. It requires the user
           exit and restart the process to take effect.
        2. It populates itself from the existing plist file (if it exists).
        3. It stops using the plist in favor of the database.
        4. It does queries and other operations using the database instead of the old hash table
           implementation.

        This patch refactors the exisiting ResourceLoadStatisticsMemoryStore class into a base
        ResourceLoadStatisticsStore class, which ResourceLoadStatisticsMemoryStore is based on.
        It adds a new ResourceLoadStatisticsDatabaseStore that is implemented in terms of SQL
        operations.

        These code changes should not have any impact on existing operations, and when enabled
        should produce the same test results.

        Reviewed by Alex Christensen.

        Do not share WebProcesses between private and regular sessions. There are some privacy concerns.
        Also, some of the WebsiteDataStore informations are passed via WebProcessCreationParameters (e.g.
        ApplicationCache path) and cannot be updated later.

        There were 2 cases where this could happen and that are fixed in the patch:
        - A process may be prewarmed with a given website data store and then later on used for a page
          associated with a different data store. We now prevent this. While this is not necessary for
          privacy reasons, it is still useful because our code currently does not support well uses
          different sessions inside a single WebProcess, as mentioned above.
        - The client can force a WebsiteDataStore swap when responding to the decidePolicyForNavigationAction,
          via the WebsitePolicies. To address the issue, we now force a process swap whenever the client
          makes such a change.

        As a result, WebProcessProxy::websiteDataStore() now makes sense and is always correct. It can
        also only contains pages whose WebPageProxy::websiteDataStore() returns the same store.

        <rdar://problem/45655856>

        Reviewed by Tim Horton and Wenson Hsieh.

        Improve our file picker on iOS so that:
        - Accepted file extensions specified in the HTML (e.g. <input type="file"> accept=".pdf">) are now
          properly reflected in the file picker. Previously, we only we only supported MIME types in the
          accept attribute that only Image / Video ones.
        - If accepted types are specified in the HTML and not of them are Video or Image types, then bypass
          the UIDocumentMenuViewController and show the file picker directly (as if the user had tapped on
          "Browse..." on that menu). Other menu items such as "Take Photo or Video" and "Photo Library" do
          not make sense if the page only accepts PDF files for example.

        Things that we should do but are not fixed in this patch:
        - Stop using UIDocumentMenuViewController entirely since it was deprecated in favor of using
          UIDocumentPickerViewController directly.
        - Add multiple selection support, which is supported both on the HTML side and in the
          UIDocumentPickerViewController API.

        Share more code between overflow and frame scrolling nodes, fixing overflow scrollbar display
        https://bugs.webkit.org/show_bug.cgi?id=195258

        Reviewed by Antti Koivisto.

        This patch moves management of scrollbar layers and scrollbar painters ("NSScrollerImp") down to
        ScrollingStateScrollingNode to be shared between frame and overflow nodes, allowing for
        scrolling thread updates of overflow scrollbars. It also moves some scrolling tree-side code
        to ScrollingTreeScrollingNodeDelegateMac to be shared between the "tree" nodes for overflow and frames.

        Layers for scrollbars are given to scrolling state nodes via setNodeLayers() now, and
        RenderLayerCompositor::updateScrollingNodeLayers() is added to provide a bottleneck to call that.
        At some point AsyncScrollingCoordinator::scrollableAreaScrollbarLayerDidChange() should be relieved
        of the responsibility of pushing scrollbar layers (but the scrolling state tree needs to hold
        references to GraphicsLayers before that becomes safe).
        
        The actual fix that allows overflow scrollbars to show is the change in
        AsyncScrollingCoordinator::scrollableAreaScrollbarLayerDidChange() that calls scrollableArea.*ScrollbarLayerDidChange()
        for all ScrollableAreas. This ensures that the CALayer is pushed onto the NSScrollerImp.

        The load optimizer would only allow itself to optimize loads whenever the web view
        who owns the page is (visible && focused), otherwises it will wait until the web view
        becomes (visible && focused). Therefore, we need a way to notify the load optimizer
        changes of statuses.

        [iOS] Programmatic paste access should be granted when copying and pasting within the same origin

        <rdar://problem/48134710>

        Reviewed by Ryosuke Niwa.

        Add support for automatically granting programmatic pasteboard access when the pasteboard identifier of the
        document requesting programmatic paste matches the identifier in the custom pasteboard data blob in the
        UIPasteboard. To do this, we send the pasteboard identifier of the document requesting the DOM paste to the UI
        process, and check this against the pasteboard identifiers for each item on the platform pasteboard. If all
        items in the platform pasteboard match the given pasteboard identifier (since we don't support writing multiple
        pasteboard items via bindings, this should only be a single item), we skip showing the paste callout and
        immediately invoke the programmatic paste handler.

        The test was attempting to disable PageCache via view preferences instead of using the
        process pool configuration flag. This would fail to disable PageCache because the
        usesPageCache preference would not prevent the creation of SuspendedPageProxy objects.
        As a result, the firing on the unload event would get delayed until the SuspendedPageProxy
        objects would get destroyed, which would lead to flakiness.

        This patch updates WebPageProxy::suspendCurrentPageIfPossible() to not create suspended
        pages proxies when the usesPageCache preference is set to false.

        Reviewed by Ryosuke Niwa.

        ResourceLoadObserver and WebProcess should exist as long as the web page (process) is running. However,
        the NetworkProcess connection can close for a variety of reasons. If the ResourceLoadObserver observes
        a load or user gesture in the WebProcess, we should attempt to reconnect to the NetworkProcess (if it
        was disconnected), just like we do for other message send cases.

        This patch switches from using the m_networkProcessConnection member (which might be null) to use the
        'ensureNetworkProcessConnection' accessor which ensures we have a valid connection for message sends.

        Reviewed by Brady Eidson.

        The StorageManager would only start listening for IPC on a given connection when
        StorageManager::processWillOpenConnection() is called. This gets called from
        WebsiteDataStore::webProcessWillOpenConnection() which gets called from
        WebProcessLifetimeTracker::webPageEnteringWebProcess().

        webPageEnteringWebProcess() was called in WebPageProxy::finishAttachingToWebProcess()
        after process-swapping. This means that IPC comming from the *provisional* process
        would not get processed and we would only start processing IPC on the provisional
        process's connection when it would get committed.

        To address the issue, this patch teaches WebProcessLifetimeTracker that a page can
        now have several processes. We also make sure that webPageEnteringWebProcess() gets
        called for the provisional process as soon as we create the provisional page, instead
        of waiting for it to get committed.

        [iOS] Web pages shouldn't be able to present a keyboard after the web view resigns first responder
        https://bugs.webkit.org/show_bug.cgi?id=195118
        <rdar://problem/43411940>

        Reviewed by Tim Horton.

        It's currently possible for websites to redirect focus into an editable element on the page by programmatically
        requesting focus within the "blur" event handler. This is because our current heuristics:

        (1) Allow programmatic focus to show the keyboard when an element is already focused; this is meant to handle
            the case where the page moves focus between different elements on the page.
        (2) And also allow programmatic focus to show the keyboard when changing activity state; this is meant to handle
            the case where a focused element should show the keyboard when first responder is restored on a web view
            (e.g. in the case where a modal view controller is dismissed, and the web view regains first responder once
            again).

        In both of these scenarios, we actually only want the keyboard to appear if the web view itself is either
        becoming the first responder, or is already the first responder. Importantly, when blurring the focused element
        by calling -[WKWebViewe resignFirstResponder] (as is the case when dismissing the keyboard by tapping 'Done' or
        focusing other platform UI), we don't want to allow the page to show the keyboard due to element focus.

        To fix this issue, we enforce that we're either becoming the first responder or already are the first responder
        before showing the keyboard due to activity state change or focused element change.

        Adopt WebCore::RegistrableDomain in WebCore::ResourceLoadStatistics and WebKit::NetworkProcessProxy
        https://bugs.webkit.org/show_bug.cgi?id=195071
        <rdar://problem/48417690>

        Reviewed by Alex Christensen and Brent Fulgham.

        This patch adopts WebCore::RegistrableDomain in WebKit::NetworkProcessProxy
        and makes the necessary infrastructure changes to support that.

        The previous HashCountedSets in WebCore::ResourceLoadStatistics are now just
        HashSets since we never used the counts for anything. This change simplified
        the IPC::ArgumentCoder<ResourceLoadStatistics> encode and decode functions.

        The patch also makes WebCore::RegistrableDomain's String constructor private.
        A new create function WebCore::RegistrableDomain::uncheckedCreateFromString()
        is introduced to better signal to users that creating a registrable domain
        object with a string may create an object that doesn't match a registrable
        domain in a valid HTTP-family URL.

        Finally, this patch harmonizes parameter and variable naming, going from
        "origin" to "domain" and "mainFrame" to "topFrame."

        added to WebKit2.xcodeproj with invalid UUIDs (they included Q's and
        Z's in hexadecimal strings). While these UUIDs haven't caused any
        problems in practice over the last six years, they are indeed invalid,
        and were discovered via an Xcode-project processing tool that did not
        anticipate their format. Fix this by removing the files from the
        project and re-adding them.

        Remove UserMediaProcessManager processState map
        https://bugs.webkit.org/show_bug.cgi?id=195056

        Reviewed by Eric Carlson.

        Before the patch, the WebProcessProxy->ProcessState map was storing the list of manager proxies and process state.
        To improve on this model, this patch does the following:
        - Move the process state to WebProcessProxy.
        - Remove the map and replace it by a set of all manager proxies.

        This simplifies the handling.
        On WebProcess side, instead of storing the sandbox extensions in each WebPage, we handle them in WebProcess directly.
        This mirrors what is being done in UIProcess and reduces the risk of inconsistencies between the two, the risk being that capture would fail.

        Have a single notion of scroll position in the scrolling tree and derive layoutViewport from it
        https://bugs.webkit.org/show_bug.cgi?id=194973

        Reviewed by Antti Koivisto.

        This patch cleans up how the scrolling tree responds to scrolls.

        First, ScrollingTreeScrollingNode::m_currentScrollPosition is "truth" for scrolling thread/
        UI process scroll position.

        On macOS where handleWheelEvent on the scrolling thread changes scroll position, the
        bottleneck is ScrollingTreeScrollingNode::scrollTo() which sets the new scroll position,
        update the visual viewport (for frame scrolls) updates the scrolledContentsLayer position,
        updates related layers on this node (counter-scrolling layers etc), and then tells the
        scrolling tree, which recurses through descendant nodes so they can adjust their layer
        positions.

        On iOS, the bottleneck is ScrollingTreeScrollingNode::wasScrolledByDelegatedScrolling(),
        which does the above other than setting scrolledContentsLayer (since we're reacting to
        layer state changes, not producing them).

        updateLayersAfterAncestorChange() is renamed to relatedNodeScrollPositionDidChange(), and
        ScrollingTree does the tree walk so classes don't have to implement
        updateLayersAfterAncestorChange() just to talk children. The ScrollingTree tree walk knows
        how to get the correct layoutViewport and to stop at frame boundaries (layer updates never
        need to cross frame boundaries).

        We preserve 'cumulativeDelta'; it's necessary for things like fixed inside overflow:scroll,
        since the fixed state was computed with the "layout" scroll position, so we have to account
        for the scroll delta since the last committed position. It's possible we could improve this
        in future.

        Since PSON makes it unreliable to retain the state in the WebProcess, move it to the process with the rest of the local storage.

        [Cocoa] Media elements will restart network buffering just before suspending
        https://bugs.webkit.org/show_bug.cgi?id=193691

        Reviewed by Eric Carlson.

        When the WebProcess receives a notification that the process is about to become
        suspended, it tells the MemoryPressureHandler to release all critical memory. This
        has the side effect of causing AVFoundation-backed media elements to dump their
        in-memory caches and start downloading media data again. Instead, media elements
        should all stop buffering media data during suspension. Add new testing SPI to
        simulate suspension and resume messages.

        [iOS] Regression(PSON) Scroll position is no longer restored when navigating back to reddit.com

        We attempt to restore the scroll position twice, on first layout and then on load completion.
        Before PSON, the scroll position would fail to get restored on first layout but would succeed
        on load completion because the view is tall enough by then. With PSON however, we would
        fail to restore the scroll position on load completion because the view would not be tall
        enough yet by this point. The reason is that the dynamic resources would not be in the memory cache
        and would then get reloaded abd finish loading *after* the load event.

        To address the issue, we now make sure to not purge the memory cache on process suspension on
        iOS if there is currently a SuspendedPageProxy in the UIProcess for this process.

        [iOS] Adjust initial scale zooming heuristics when changing view scale
        https://bugs.webkit.org/show_bug.cgi?id=194995

        Reviewed by Tim Horton.

        Currently, we only zoom to the new initial scale iff we're exactly at initial scale before changing the view
        scale. This was done so that if a user zoomed in really far and then increased the view scale, we wouldn't end
        up zooming out as a result. However, this leads to confusing behavior in the case where the user has manually
        changed the zoom scale to something close to (but not exactly) initial scale, and then attempts to zoom in
        further using view scale. In this case, we'll end up keeping page scale the same, so it looks like nothing is
        happening.

        To fix this, we tweak our heuristics for determining whether to jump to initial scale; if the view scale is
        increasing and the new initial scale is greater than the current scale, zoom to initial scale. Likewise, if the
        view scale is decreasing and the new initial scale is less than the current scale, zoom to initial scale.

        Introduce and adopt new class RegistrableDomain for eTLD+1
        https://bugs.webkit.org/show_bug.cgi?id=194791
        <rdar://problem/48179240>

        Reviewed by Alex Christensen, Fujii Hironori, and Brent Fulgham.

        A new API test was added. Plenty of existing layout tests under
        http/tests/resourceLoadStatistics/ and http/tests/storageAccess/ test the code.

        This patch introduces and adopts a new class called WebCore::RegistrableDomain
        which represents a domain's eTLD+1 (effective top level domain plus one) and is
        the basis for the term "site," as in same-site. Other popular names include
        high-level domain, primary domain, and top privately controlled/owned domain.
        Effective top level domains are enumerated on the Public Suffix List
        (https://publicsuffix.org).

        This class just uses the full domain for when the Public Suffix List cannot help
        finding the registrable domain and for WebKit ports that haven't enabled
        PUBLIC_SUFFIX_LIST. It also uses the string "nullOrigin" as a representation
        for the null or unique origin (this matches how these origins were handled
        before).

        The implementation is a wrapper around a String and the functions and class
        members that now make use of this new class used to handle regular String
        objects which didn't help much in terms of type safety or guarantees that the
        string had already been converted to an eTLD+1.

        We've at least two bad bugs in the Storage Access API because of confusion
        between a URL's eTLD+1 and its host. The usage of WebCore::RegistrableDomain
        will prohibit such bugs in the future.

        Partitioning in WebKit also uses eTLD+1 to a large extent. I plan to adopt
        WebCore::RegistrableDomain for partitioning in a later patch.

        This patch also enhances parameter naming by:
        - Removing parts that refer to "primary" as in primaryDomain.
        - Replacing references to "TopPrivatelyControlledDomain" with "RegistrableDomain."
        - Replacing references to "TopPrivatelyOwnedDomain" with "RegistrableDomain."
        - Using the term "domain" consistently instead of e.g. "host."

        A follow-up patch will continue backwards in call chains to create
        WebCore::RegistrableDomain objects as early as possible instead of using strings.
        I did not do that work here in the interest of patch size.

        A prewarmed Web process should have a process assertion.
        https://bugs.webkit.org/show_bug.cgi?id=195006

        Reviewed by Geoffrey Garen.

        To make sure the prewarm message is handled in the Web process before the process is suspended,
        the process should have a process assertion. This can be fixed by sending the prewarm message
        inside WebProcessPool::initializeNewWebProcess, since all message sent inside this method are
        guaranteed to be handled before the WebContent process is suspended.

        This patch is based on Chris Dumez' idea and obervation of the issue.

        [iOS] Callout menu overlaps in-page controls when editing a comment in github.com's issue tracker
        https://bugs.webkit.org/show_bug.cgi?id=194873
        <rdar://problem/46701974>

        Reviewed by Tim Horton.

        On the topic of supporting web-based rich text editors on iOS, one problematic area has always been handling
        conflicts between platform UI (i.e., the system callout menu) and in-page text editing controls. This issue
        comes up in websites that don't use the "hidden contenteditable" approach to rich text editing, but also show
        additional controls in a toolbar or contextual menu above the selection. In these cases, what often happens is
        that system controls overlap controls in the page.

        Luckily, the iOS callout menu (i.e. the private UICalloutBar) is capable of presenting with a list of "evasion
        rects" to avoid; if the callout bar would normally intersect with one of these rects, then a different
        orientation that does not intersect with one of these rects is chosen instead. Currently, the only rect added
        here by UIKit when presenting the callout menu is the bounding rect of the on-screen keyboard, but after
        <rdar://problem/48128337>, we now have a generalized mechanism for offering additional evasion rects before
        UIKit presents the callout menu.

        This patch adopts the mechanism introduced in <rdar://problem/48128337>, and introduces a heuristic for
        determining the approximate location of controls in the page which might overlap the callout menu. This
        heuristic works by hit-testing for clickable (but non-editable) nodes above the bounds of the selection, which
        are additionally not hit-tested by advancing outwards from any of the other edges of the selection bounds.
        Additionally, any hit-tested nodes whose bounding rects are very large (relative to the content view size) are
        ignored (this deals with scenarios where the body or a large container element has a click handler). We then add
        the bounding rects of each of the nodes that fit this criteria to the list of rects for UIKit to avoid when
        presenting the system callout menu.

        The result is that WebKit will, by default, avoid overlapping anything that looks like controls in the page when
        showing a callout menu in editable content. In practice, this fixes overlapping controls on most websites that
        roll their own context menu or toolbar in their rich text editor.

        When process-swapping, we would create a new WebPage in the new process, which would
        call restoreSessionInternal() to restore the HistoryItems based on the UIProcess's
        backforward list. The issue is that this session restoring would send HistoryItem
        updates back to the UIProcess. Without PSON, this would be unnecessary but harmless.
        With PSON though, this may end up overwriting values set by the previous process,
        such as the scroll position.

        Address the issue by temporarily disabling the HistoryItem update notifications to
        the UIProcess while restoring a session.

        After we construct a SuspendedPageProxy and before we send the IPC to the WebProcess to
        ask it to suspend, start a 10 seconds timer. If the process does not answer the request
        to suspend before the timer fires, we destroy the SuspendedPageProxy so that we do not
        keep a hung process around.

        For the WebProcessCache, we now call WebProcessProxy::isResponsive() on the process
        before adding it to the cache. Internally, this relies on an IPC handshake with the
        WebProcess. If the process is not responsive, we do not add it to the cache and we
        shut it down. If it is responsive then we proceed normally with adding it to the

        Following r241311, if a web view becomes first responder and is then moved offscreen (or obscured, hidden, or in
        the case of WebKitTestRunner, its UIWindow loses its status as keyWindow), we end up holding on to the input
        view update deferral token indefinitely, waiting for the current focused element to be blurred or refocused.

        This also manifests other user-facing bugs, the most common of which is the keyboard occasionally remaining
        onscreen after typing a URL in the unified field in MobileSafari and hitting Return, in the case where there is
        no autofocused element on the page.

        To fix this, when becoming the first responder, additionally install a callback to detect when the page is
        finished handling the activity state change, and invalidate the input deferral token then. This retains the
        behavior where calling -becomeFirstResponder on the web view while a different view is focused will keep the
        keyboard stable, since the focused element message from the web process should be dispatched when handling the
        activity state change within the web process.

        Of course, the web process may not be responsive at all while the web view is still in the view hierarchy, in
        which case we may still end up deferring input view updates indefinitely. In this case, we maintain a separate
        watchdog timer with a short delay, after which we unconditionally invalidate the token.

        [WKWebView _reloadWithoutContentBlockers] relies on a ReloadOption flag that is passed to WebCore
        instead of using WebsitePolicies.contentBlockersEnabled flag. If the reload causes a process swap
        due to PSON, then the new process does not know about this ReloadOption and fails to honor it.

        Since the modern way to do this is WebsitePolicies, and since WebsitePolicies are properly
        propagated cross-process in case of process swap, this patch updates _reloadWithoutContentBlockers
        to set a flag on the Navigation which we use to later set the WebsitePolicies.contentBlockersEnabled

        Reviewed by Carlos Garcia Campos.

        Adds new API to manage a collection of content extensions on disk (including compilation
        of new ones) using WebKitUserContentFilterStore; the associated WebKitUserContentFilter
        type (which represents a compiled content extension); and the functions needed to enable
        and disable them for a given WebKitUserContentManager.

        The WebKitUserContentFilterStore public API is expressed in abstract terms of "saving"
        filters into the store (which involves compiling the JSON source rule set); and "loading"
        them back as main operations. This way we do not disclose to users of the API any detail
        about compilation, nor how contents are laid out on disk, and the documentation explicitly
        tells about only using the provided functions to manipulate the on-disk contents. This
        way we allow ourselves some leeway if the implementation needs changing in the future.

        The issue was caused by us mistakenly process-swapping for a same-site server side redirect.
        The reason we were getting it wrong is because the logic in

        when a server-side redirect occurs in a provisional process. In such case, the source process

        Remove all IPC plumbing for getTypesByFidelityForItemAtIndex, now that the types in fidelity order have been
        rolled into PasteboardItemInfo.

        Additionally, remove support for subresource URL replacement. This feature was originally added with the
        intention that private clients (i.e. Mail) would intercept pasted or dropped images and replace their URLs.
        However, since <rdar://problem/43216836>, our strategy for this scenario has changed, such that WebKit now
        handles the drop/paste, and later delivers the image data to the client via NSFileWrappers in the UI process.
        At this time, there are no adopters of this SPI, and no adopters of the V2 injected bundle editing client. As
        such, we can simply revert all of this to its state prior to the introduction of the replacement URL SPI, with
        the exception to changes in WKBundlePageEditorClient.h, wherein there is a nonzero (but likely tiny) chance of
        completely breaking binary compatability with any third parties on macOS which may have tried to adopt
        subresource URL replacement.

        [iOS] Keyups for non-modifier keys identified as "Dead" when not focused in a content-editable element

        Use the same code path for key events to editable elements and non-editable elements.

        Currently we have different code paths for hardware key events depending on whether the active element
        is editable or non-editable. Historically to support dispatching DOM keyboard events for hardware key
        presses this differentiation was a necessary workaround for UIKit's event processing precedence of
        interpreting key events for system text editing commands and app commands before dispatching unhandled
        key events to WebKit. This workaround intercepted raw key UIEvents and manually reconstructed a
        WebEvent from it. However there is not enough information in an UIEvent to reconstruct a WebEvent that
        is identical to the WebEvent that UIKit would have dispatched. In particular, keyup UIEvents always have
        empty modified and unmodified input strings. The UIKit keyboard machinery maintains additional state
        that is necessary to manufacture the correct WebEvent corresponding to a UIEvent.

        As a side benefit of this change, with the exception of modifier flag changes, both hardware and software
        key events use the same code path.

        (-[WKContentView _elementDidBlur]): Call [self _endEditing] so that we dismiss any open form controls
        (e.g. a <select> popover menu). Currently this happens either by -_requiresKeyboardWhenFirstResponder

        editable and non-editable elements we need to ensure that the WKContentView is the keyboard delegate
        when the popover is presented.

        Support -makeTextWritingDirectionLeftToRight: and -makeTextWritingDirectionRightToLeft: in WKWebView on iOS.
        To match behavior in native UITextViews on iOS, we implement these methods by changing the *base* writing
        direction, rather than the text writing direction (this is in contrast to macOS, which has different
        NSResponder methods for changing the base writing direction as opposed to the text writing direction).

        Additionally fixes the implementation of -makeTextWritingDirectionNatural:, which currently attempts to change
        the text writing direction instead of the base writing direction.

        Regression(PSON) Navigating quickly back and forth can lead to getting 'about:blank' in the backforward list
        https://bugs.webkit.org/show_bug.cgi?id=194717
        <rdar://problem/47884404>

        Reviewed by Brady Eidson.

        When the client does a history navigation, the UIProcess sends a WebPage::GoToBackForwardItem IPC to the
        WebProcess and the WebProcess sends a WebPageProxy::BackForwardGoToItem IPC back to the UIProcess to
        update the current item in the BackForwardList. This means that there is a slight delay between the
        point a client requests a history navigation and the point where the BackForwardList's current item gets
        update. This delay is pre-existing behavior and not new to PSON.

        However, with PSON enabled, if we decide to process-swap for the history navigation, we'll tell the
        previous (committed) process to ignore the load and we ask a new (provisional) process to do the history
        navigation. When the previous process receives the request to ignore the history navigation, it restores
        the History's current item to the one previous the navigation, which sends a WebPageProxy::GoToBackForwardItem
        IPC to the UIProcess to update the BackForwardList as well. In parallel, the new process starts the
        history navigation and also sends a WebPageProxy::GoToBackForwardItem to update the BackForwardList's
        current item as well. We end up with a race between the 2 GoToBackForwardItem IPC messages coming from
        the old and new process. If the old process's message loses the race, we end up with the wrong current
        history item getting set in the UIProcess. Later, when we commit the provisional load and try to suspend
        the previous page, we would save the SuspendedPage on the *wrong* BackForwardList item. If one tries to
        load this BackForwardList item later, we'll use its SuspendedPage and try to unsuspend it. However,
        because the PageCache entry is saved on another HistoryItem than the one getting loaded in the WebProcess
        side, we attempt to do a regular load instead of a PageCache restore. We end up failing the load because
        pages cannot trigger new loads while in page cache. Because the load fails, we end up loading the
        initial empty document and this is how we end up with 'about:blank' in the back forward list.

        To address the issue, update WebPageProxy::backForwardGoToItem() to ignore messages from the old/committed
        WebProcess when there is a pending provisional load. If the committed processes starts a legit new
        load, it would clear any existing pending provisional load before attempting the call backForwardGoToItem().
        As a result, ignoring such messages from the old processes when there is a pending provisional load is
        safe.

        In the future, we should probably move more of the history / backForwardList management to the UIProcess
        to avoid this sort of issues. This would be a much larger refactoring though so I am going with this
        simpler fix that is easily cherry-pickable for now.

        The goal of this refactoring is to, at some point use the regular network process load path for service worker loads.
        This should simplify things and allow less IPC exchanges, for instance in the case of fetch not handled by service worker.

        Introduce two IPC messages for supporting redirect responses and allow the didReceiveResponse/continueDidReceiveResponse
        handshake for navigation loads.

        This makes ServiceWorker having to buffer load information for this particular case.

        REGRESSION (r240446): Storage Access API does not handle domains consistently
        https://bugs.webkit.org/show_bug.cgi?id=194664

        Reviewed by Alex Christensen.
        
        During my refactoring of the ResourceLoadStatistics code, I introduced two bugs:
        (1) I neglected to be consistent in my use of 'primaryDomain', causing some Storage
        Access API code paths to store approves under one domain (e.g., 'www.example.com'),
        while checking status under the eTLD+1 (e.g., 'example.com'). The exact string matching
        requirement caused these to get missed.

        (2) I used a move operator before a final set of copies of domain names, leading to
        some empty strings being passed to Storage Access API calls.

        Both issues are corrected in this patch.

        In case Caches::dispose is called, clearMemoryRepresentation might be called if there is no active cache.
        We also ensure to not clear the memory representation if there is any remaining removed cache.
        Update the clearMemoryRepresentation assertion to take that into account.

        In case a Caches is cleared twice, the clearMemoryRepresentation assertion will assert while it should not.
        In that case m_storage is null the second time. Update the assertion accordingly.

        [PSON] Introduce a WebContent Process cache
        https://bugs.webkit.org/show_bug.cgi?id=194594
        <rdar://problem/46793397>

        Reviewed by Geoff Garen.

        Introduce a WebContent Process cache to reduce the number of process launches when
        process swap on navigation is enabled, and to reduce the power cost of the feature.

        If a WebProcess loaded pages from a single registrable domain then it is eligible
        for the cache. When process-swapping on navigation to a new registrable domain, we
        now attempt to retrieve a process from the cache for the domain in question instead
        of always launching a new one.

        The WebProcess cache currently has the following attributes:
        - It may contains 4 processes per GB of RAM the machine has, up to 30 processes.
        - WebProcesses automatically get evicted from the cache after 30 minutes.
        - If the application is no longer the active app, then the cache will get cleared
          after 5 minutes.
        - WebProcesses that are in the cache are reported as "(Cached)" in Activity Monitor.

        The WebProcess cache is currently disabled by default and can by enabled by the
        client via SPI.

        This is important because the logic in WebProcessPool::processForNavigation() relies on

        process so that it can update its name in Activity Monitor.
        We also need to stop holding a strong reference to the WebProcessPool whenever the process
        is in the cache, similarly to what we do for pre-warmed processes, given that such processes
        should not keep the process pool alive.

        (WebKit::WebProcessProxy::isAllowedToUpdateBackForwardItem const):
        (WebKit::WebProcessProxy::updateBackForwardItem):
        In case of client-side redirects, the previous process would sometimes send an IPC causing
        the UIProcess' backforward list item to get updated with the pre-redirect URL after we've
        already redirected. This previously would be unlikely to occur because we do not suspend
        client-redirect pages and their process would normally exit before getting a chance to send
        the IPC. However, with the process cache, the bug became obvious as the process would stay
        alive and send up the "bad" IPC. To address the issue, we now only let the IPC update the
        item if the item's page is (still) associated with the process. In the future, we may want
        to update the IPC so that it gets sent to the WebPageProxy instead of the WebProcessProxy.

        (WebKit::WebProcessProxy::processDidTerminateOrFailedToLaunch):
        If a cached WebProcess crashes, remove it from the cache so that we do not attempt to use
        it for a load later.

        (WebKit::WebProcessProxy::canBeAddedToWebProcessCache const):
        Only cache WebProcesses that have loaded a single registrable domain. Also prevent caching
        for service worker and inspector processes.

        (WebKit::WebProcessProxy::maybeShutDown):
        If the process is cacheable, add it to the cache instead of shutting it down right away.

        (WebKit::WebProcessProxy::canTerminateAuxiliaryProcess):
        Make sure we do not attempt to terminate a processes that is in the cache.

        (WebKit::WebProcessProxy::didStartProvisionalLoadForMainFrame):
        Whenever a main frame provisional load starts, make sure we update the process's associated
        registrable domain. nullopt indicates that there is no associated domain yet. Null string
        indicates that the process is associated with several registrable domain and is therefore
        not eligible for caching.

        When the WebProcess receives a notification that the process is about to become
        suspended, it tells the MemoryPressureHandler to release all critical memory. This
        has the side effect of causing AVFoundation-backed media elements to dump their
        in-memory caches and start downloading media data again. Instead, media elements
        should all stop buffering media data during suspension. Add new testing SPI to
        simulate suspension and resume messages.

        Responsiveness timers are too expensive for frequent events
        https://bugs.webkit.org/show_bug.cgi?id=194003

        Reviewed by Geoffrey Garen.

        With each event, we set a responsivness timer to check if the WebProcess
        is responsive, and reset the timer when the WebProcess sends an answer.

        For frequent events (e.g. wheel events, mouse force events, etc),
        we are spamming the kernel with hundreds of timers per second.
        That is a bit inefficient.

        Another source of inefficiency comes from the timer implementation
        itself. Stopping a RunLoop::Timer removes the timer from every mode
        and invalidate the timer. It becomes costly since we do it a lot.

        With this patch, I tweak ResponsivenessTimer and its use to minimize
        how often we schedule system timers.

        The first change is to not stop the timer when we get the stop()
        calls if we expect more events to come in. Instead, we keep track
        if we care about the timeout or not in the attribute "m_waitingForTimer".
        When the next event starts, we can reschedule the timer without ever
        having told the kernel about the stop.
        If there are no next events, the timeout fires but m_waitingForTimer
        is false. To avoid idle wake up, the lazy stop is only used when having
        following events is common.

        The second improvements comes from not even rescheduling the timer
        when restarted. Instead of changing the timer, we let the original timer
        fire and re-shedule a new one with the missing time.

        For more context, also see patches r240759 and r240944.

        Add a helper to take and invoke the current DOM paste completion handler (if it exists) with the given result,
        and then dismiss the shared callout bar. Returns whether or not the paste completion handler exists. Invoked

        get stuck in a bad state in the case where WKWebView has been subclassed, overrides `-paste:`, and does not
        invoke the superclass method (which calls back into `-[WKContentView pasteForWebView:]`). There are a few
        possibilities here:
        1. WKWebView's `-paste:` action is not overridden. In this case, we will call back into `-pasteForWebView:`,
           which will notice that we have a pending paste completion handler and invoke it.
        2. WKWebView's `-paste:` action is overridden and does not call back into the content view. In this case, we
           will invoke the paste completion handler in `-_didPerformAction:sender:`.
        3. WKWebView's `-canPerformAction:withSender:` is overridden to include additional actions. In this case, we may
           get a call to invoke a different action selector while waiting for a potential paste action. If this happens,
           prevent the DOM paste in `-_willPerformAction:sender:` prior to handling the other action.

        (-[WKContentView _requestDOMPasteAccessWithElementRect:completionHandler:]):

        Attempt to find a good target presentation rect when showing the callout menu. First, we will try to use the
        rect of the element the user has interacted with when triggering the paste. If such an element is too large or
        does not exist, we fall back to presenting the callout menu near the user's last touch location (with a small
        amount of margin, such that the action doesn't overlap with the user's finger, stylus, etc.).

        The InjectedBundle SPI can retain the WebPage or wrapping objects (WKWebProcessPlugInBrowserContextController/WKBundlePageRef).
        This can make it so WebPage::close is called before WebPage::~WebPage, and if the SuspendedPageProxy is reused for a subsequent
        navigation to the same domain, the WebProcess is reused with a different WebPage instance with the same PageID, which causes problems
        when another WebPage registers message handlers and then the previous WebPage is destroyed, which removes both message handlers.

        Reviewed by Darin Adler.

        It is incorrect to use g_unsetenv() here because it is MT-Unsafe. We know that it is
        impossible and unreasonable to expect the application has not started other threads at this
        point, and threads will be calling getenv(). WebKit itself has probably already started
        threads of its own.

        Fortunately, the remote inspector in the web process is already prepared to deal with
        failure to connect to the inspector server, so we don't need to do anything except stop
        messing with the environment.

        [WK2][macOS] Avoid creating new CVDisplayLink objects for each WebProcess

        Reviewed by Tim Horton.

        Avoid creating new CVDisplayLink objects for each WebProcess. We really only need one per
        display, creating such object is expensive and it is even worse in a PSON world where we
        swap process on navigation.

        This patch moves the DisplayLink storing from WebProcessProxy to WebProcessPool. Also,
        a DisplayLink can now be associated to several IPC connections instead of having a 1:1
        mapping. When a DisplayLink no longer has any observers, we now merely stop it instead
        of destroying it.

        [GTK] Implement back/forward touchpad gesture
        https://bugs.webkit.org/show_bug.cgi?id=193919

        Reviewed by Michael Catanzaro.

        Move ViewSnapshotStore and ViewGestureController from Cocoa/Mac directory
        to UIProcess/, also move some parts of mac/ViewGestreControllerMac.mm to
        ViewGestureController.cpp, split up Mac- and iOS-specific parts of
        ViewSnapshotStore.cpp into mac/ViewSnapshotMac.mm, then implement 2-finger
        touchpad swipe back-forward gesture for GTK based on that.

        To avoid name conflict, rename existing ViewGestureController class inside
        UIProcess/API/gtk/WebKitWebViewBase.cpp into TouchGestureController.

        Since GTK gestures can only work with 3 or 4 fingers, treat horizontal
        scrolling events as a swipe as long as there's nowhere to scroll in that
        direction and web page doesn't handle the scrolling.

        This is only allowed for touchpads, even though it can theoretically work
        with touch mice and trackpoints.

        The gesture requires every item in back-forward list to have a snapshot.
        There's already an existing infrastructure for that, so the patch changes
        a bunch of #if PLATFORM(COCOA) statements to also check for GTK platform.
        The snapshots have to be taken in sync, so the implementation draws webview
        widget into a Cairo image surface.

        The gesture is disabled by default, and can be enabled by setting the newly
        added 'enable-back-forward-navigation-gestures' property in WebKitSettings to
        true.

        Gesture drawing is implemented via Cairo. When the gesture is active, the
        actual page is drawn into a Cairo group, which is then drawn together with
        a given snapshot, as well as dimming and a drop shadow over the "lower" layer.

        Also add a memory pressure handler that clears snapshot store when low on memory.

        This is the WebKit equivalent of - (UIView *)snapshotViewAfterScreenUpdates:(BOOL)afterUpdates;
        This makes our snapshotting API more predictable and reliable on iOS devices,

        We should block CoreServices in newer versions of macOS. In order to achieve this we need to avoid calling
        _RegisterApplication before entering the sandbox, since this call will open up a connection to CoreServices.
        The call to _RegisterApplication is moved to ChildProcess::updateProcessName, since it is needed to
        successfully update the process name. The call to ChildProcess::updateProcessName is made after entering
        the sandbox.

        Fix XCBuild issue related to codesigning WebContent process
        https://bugs.webkit.org/show_bug.cgi?id=193799
        <rdar://problem/47533890>

        Reviewed by Brent Fulgham.

        Building with XCBuild enabled results in the error message "cannot
        read entitlement data" when trying to codesign the macOS XPC
        processes. The reason for this error message is that there is a build
        step that deletes any previous "stale" generated .xcent file before
        building up a new one. With XCBuild enabled, the build steps got
        re-ordered, such that the step that deletes this file could get
        executed after the steps that build up the file. The built-up set of
        entitlements is now gone, and the build process fails when `codesign`
        tries to access it.

        The apparent quick-fix to this problem -- of tweaking dependencies so
        that the build steps execute in the desired order -- wouldn't work
        with XCBuild. Establishing these dependencies would require both
        having multiple build phases produce the same .xcent file as output,
        as well as a build phase that has this file as an input and an output.
        XCBuild either forbids or frowns upon these configurations.

        Ultimately, the solution that worked was to take over complete control
        of the codesigning process. This means (a) not specifying a base
        .entitlements file that XCode uses to start with (and which was
        subsequently altered via custom build scripts), (b) not letting XCode
        automatically and silently inject a 'get-task-all' entitlement used to
        facilitate debugging (we now add that entitlement by hand), and (c)
        building up all of our entitlements by hand via a single custom
        script. Because of the addition of this custom script, many other
        scripts and entitlements files could now be removed.

        Without this patch, changing the preference for printing the background has no effect.
        This patch fixes that, and I verified it manually by checking "Print backgrounds" in Safari's print menu.
        Unfortunately, the only way to test this is actually printing because only values from WebPageProxy::preferences
        or WebPageProxy::configuration's preferences are exposed to the API, but values from WebPageProxy::preferencesStore
        are used when printing.  Actually printing verifies this change fixes the bug.

        Use an OptionSet to represent the bitmask of keyboard modifier flags. This improves type safety
        and makes debugging more enjoyable because our LLDB pretty-printers have built-in support for
        OptionSet.

        While I am at it, make WebEvent::Modifier an enum class. It is currently an enum. This makes
        this enum more closely match WebCore::PlatformEvent::Modifier.

        We release the WKShareSheet (which holds our reference to the NSSharingServicePicker)
        under sharingServicePicker:didChooseSharingService:. On older versions of macOS,
        there was nothing keeping the NSSharingServicePicker alive inside
        showRelativeToRect:ofView:preferredEdge:, thus the whole chain of references would
        fall and result in sending a message to a released NSSharingServicePicker.

        presentation is complete.

        they are not. This facility was initially opt-in by setting
        WK_ENABLE_CHECK_XCFILELISTS until other pieces were in place and until
        the process seemed robust. Its now time to enable this facility and
        make it opt-out. If there is a need to disable this facility, set and
        export WK_DISABLE_CHECK_XCFILELISTS=1 in your environment before
        running `make` or `build-webkit`, or before running Xcode from the

        Simon Fraser suggested a neat improvement over my previous optimization
        of ResponsivenessTimer.

        Instead of reseting the deadline with every event, we can let the timer
        fire and add the missing time from the last start.

        I implemented that behavior in the new Deferrable Timer class and use
        it from ResponsivenessTimer.

        PageOverlayController's layers should be created lazily
        https://bugs.webkit.org/show_bug.cgi?id=194199
        rdar://problem/46571593

        Reviewed by Tim Horton.
        
        Expose PageOverlayController::hasDocumentOverlays() and hasViewOverlays()
        and use them to only parent the overlay-hosting layers when necessary.

        For document overlays, RenderLayerCompositor::appendDocumentOverlayLayers() can
        simply do nothing if there are none. Updates are triggered via Page::installedPageOverlaysChanged(),
        which calls FrameView::setNeedsCompositingConfigurationUpdate() to trigger the root layer
        compositing updates that parents the layerWithDocumentOverlays().

        View overlays are added to the layer tree via the DrawingArea. When we go between having
        none and some view overlays, Page::installedPageOverlaysChanged() calls attachViewOverlayGraphicsLayer()
        on the ChromeClient, and the DrawingArea responds by calling updateRootLayers() and scheduling a
        compositing flush (this has to be done manually because view overlay layers are outside the
        subtree managed by RenderLayerCompositor).
        
        Now that GraphicsLayers are ref-counted, we can let the DrawingArea simply retain its m_viewOverlayRootLayer;
        there is no need for RenderLayerCompositor::attachRootLayer()/detachRootLayer() to do anything with view
        overlay layers. This implies that a page can navigate (new FrameView) and view overlays will persist, without
        having to be manually removed and re-added. We can also remove the Frame argument to attachViewOverlayGraphicsLayer().

        [iOS] Consistent 1 sec hang when triggering modal alerts while handling synchronous touch events
        https://bugs.webkit.org/show_bug.cgi?id=194140
        <rdar://problem/47728098>

        Reviewed by Tim Horton.

        Currently, the UI process hangs when attempting to synchronously present modal UI from the web process while the
        UI process is waiting for sync IPC in the web process. While we have logic to generally mitigate IPC deadlock in
        this scenario by dispatching the web process' sync IPC immediately with the intention of allowing the web
        process to finish processing sync IPC (and consequently unblock the UI process), this fails in the case where
        the sync IPC message from the web process to the UI process requires main thread execution for an arbitrary
        amount of time (for instance, modal alert dialogs). In this case, we'll end up in a state where we've handled
        the web process' sync IPC in the UI process, yet we can't resume execution since the web process is still
        blocked.

        By far the most egregious scenario in which this manifests is during synchronous gesture recognizer IPC, i.e.
        grabbing position information from the UI process, and handling touch events synchronously. Luckily, these are
        also cases where (1) we know sync IPC may safely time out, and (2) the presentation of modal UI from the web
        process should cause the gesture recognizers to fail anyways. As such, we can mitigate these scenarios in the
        web process by responding to the these pending sync IPC messages *before* sending our own sync IPC to the UI
        process.

        The issue was happening when the page is triggering a cross-site navigation while in the middle of parsing. This would cause us to
        start a new provisional load in a new process before the previous process sends the DidFinishLoadForFrame() IPC to the UIProcess.
        Getting such IPC after a provisional load has started would mess up our state machine and trip assertions.

        This patch restores non-PSON behavior which is that the previous load in the old process now gets stopped so that no DidFinishLoadForFrame()
        / DidFailLoadForFrame() gets sent. To achieve this behavior, I introduced a new "StopAllLoads" PolicyAction that we now send the old
        process when the load is continuing in a new process, instead of sending it "Ignore".

        When a user-agent-provided interaction, such as panning or zooming on iOS, uses a set of touches, we should dispatch a pointercancel

        Previously, when the client would call setPageAndTextZoomFactors() on the WebPageProxy,
        we would update the WebPageProxy's corresponding data members and send an IPC to the
        WebProcess to apply the zoom factors.

        The issue is that on process crash or process-swap, we never communicate those zoom factors
        to the new WebProcess. Even if the client were to call setPageAndTextZoomFactors() with
        the same factors again, it would be a no-op since the WebPageProxy's data members already
        reflect the expected values.

        To address the issue, pass both the page zoom and the text zoom factors to the WebProcess
        via WebPageCreationParameters. This way, there is no need to send an extra IPC and we're
        sure the WebPageProxy's factors are properly applied to the WebPage on WebContent process
        side upon creation (whether after a crash or a process swap).

        https://bugs.webkit.org/show_bug.cgi?id=194083

        Reviewed by Tim Horton.

        We think this crash is a regression from r236966. Prior to r236966, we could only called
        removeSwipeSnapshot() only when m_provisionalOrSameDocumentLoadCallback was set but now
        we can call it either when m_snapshotRemovalTracker::start was called, or it had been reset.
        This can result in m_webPageProxyForBackForwardListForCurrentSwipe getting cleared before
        InteractiveUpdateHandler is called by UIGestureRecognizer, resulting in the crash.

        This patch tries to restore the behavior prior to r236966 by only invoking removeSwipeSnapshot()
        when SnapshotRemovalTracker has a valid removal callback set.

        Unfortunately no new tests since there is no reproducible test case, and neither API tests
        nor layout tests seem to have the capability to trigger swipe gestures via UIGestureRecognizer,
        which is required for this crash to occur. Notably, back-forward swipe tests I enabled in
        r240765 bypass UIKit and emulates the action instead.

        <rdar://problem/47570443> Responsiveness timers are too expensive for frequent events
        https://bugs.webkit.org/show_bug.cgi?id=194003

        Reviewed by Geoffrey Garen.

        The problem here is specific to wheel events.

        For every wheel event, we start a responsiveness timer and send
        a ping to the WebProcess. When the WebProcess respond, we stop the timer.

        The cost of setting up the timers adds up since we get many events.

        The first step to improve the situation was to switch ResponsivenessTimer
        to WebCore::Timer. Since WebCore::Timer reuse the same CFRunLoopTimerRef,
        we save the allocation/deallocation, insertion in the event loop, etc.

        Using WebCore::Timer saves some instructions but we were still hitting
        the kernel at 120hz to set up then kill each timer.
        The second improvement of the patch is to avoid that by not killing the timer
        when we hear back from the WebProcess.

        Instead of killing the timer, we let it run and ignore the result.
        When the next event comes, we reschedule the existing timer.
        This brings down the timers to 60Hz, the same rate as the events.

        The very last event does time out. In that case, we have a bad idle wake up:
        we wake up a sleeping CPU do do nothing.
        In the case of wheel events, this is fine since we saved a bunch of CPU already.
        For all the other cases, I kept the normal operating mode to avoid the idle wake.

        [iOS] REGRESSION (r238635): Text area fails to re-focus after dismissal of keyboard on support.apple.com

        It is unnecessary to relinquish first responder status when a user explicitly dismissing
        the keyboard. Moreover, doing so prevents key commands from being intercepted when a
        hardware keyboard is subsequently attached.
        
        Following r238635 a page becomes focused (accepting of keyboard input) and defocused
        when the WKContentView becomes first responder and resigns first responder, respectively.
        When a user explicitly dismisses the keyboard by tapping Done (iPhone) or the hide keyboard
        button (iPad) then UIKit tells WKContentView to resign its first responder status only
        to make its superview, WKWebView, first responder. When a person subsequently taps on the
        page again, the WKContentView requests to become the first responder. However changes to
        page focus are not guaranteed to be sent to the WebProcess immediately (WebPageProxy::activityStateDidChange()
        will schedule an update). In particular, they are not guaranteed to be sent before the
        WebProcess is told about a tap. Therefore, the WebProcess has out-of-date information on
        focus state of the page. Instead we should detect when WKWebView is being asked to resign
        as a result of the keyboard dismissal and refuse the request, taking care to end the current
        editing session, blur the focused element, and dismiss the on-screen keyboard.

        Use the same code path for key events to editable elements and non-editable elements.

        Currently we have different code paths for hardware key events depending on whether the active element
        is editable or non-editable. Historically to support dispatching DOM keyboard events for hardware key
        presses this differentiation was a necessary workaround for UIKit's event processing precedence of
        interpreting key events for system text editing commands and app commands before dispatching unhandled
        key events to WebKit. This workaround intercepted raw key UIEvents and manually reconstructed a
        WebEvent from it. However there is not enough information in an UIEvent to reconstruct a WebEvent that
        is identical to the WebEvent that UIKit would have dispatched. In particular, keyup UIEvents always have
        empty modified and unmodified input strings. The UIKit keyboard machinery maintains additional state
        that is necessary to manufacture the correct WebEvent corresponding to a UIEvent.

        As a side benefit of this change, with the exception of modifier flag changes, both hardware and software
        key events use the same code path.

        We do not support having more than one WebPage in a WebProcess with the same page ID. As a result,
        if we decide to reuse an existing process on process-swap, we need to make sure that we either use
        its suspended page (when possible, meaning that it is for the right HistoryItem / page) or we need
        make sure we drop the existing suspended page for this process / pagePID combination, so that the
        WebPage on WebProcess side gets closed before we attempt to do the new load.

        We were doing this correctly in 2 places in WebProcessPool::processForNavigationInternal() but failed
        to do so in a third place, when doing back to a HistoryItem which does not have a SuspendedPage but
        whose process is still alive (presumably because it is kept alive by another suspended page). This
        patch fixes this third place to remove any suspended page in the process for the current page before
        reusing the process. An assertion was also added to the call site in
        WebPageProxy::receivedNavigationPolicyDecision() to make sure we catch this more easily in the
        future.

        [GTK] gdk_cairo_draw_from_gl() in AcceleratedBackingStoreWayland fails in GtkInspector's magnifier
        https://bugs.webkit.org/show_bug.cgi?id=193903

        Reviewed by Michael Catanzaro.

        The problem is that the GL context used by WaylandCompositor can't share resources with the one used by GTK+
        when painting with gdk_cairo_draw_from_gl(). Accelerated compositing in Wayland works only because
        WaylandCompositor makes the context current only once on initialization. So, when we render the first frame on
        accelerated compositing mode, GTK+ is rendering in non-GL mode, and switches to the GL mode when
        gdk_cairo_draw_from_gl() is called. Since GTK+ didn't have a GL context yet, the first frame is always rendered
        by GTK+ using the software fallback (glReadPixels). The thing is that the first time gdk_cairo_draw_from_gl() is
        called, GTK+ creates a GL context for painting that is made current, and it will remain the current one
        forever. The first frame fails to render with "GL_INVALID_OPERATION in glBindTexture(non-gen name)" because the
        texture created in WaylandCompositor GL context can't be accessed from GTK+ GL context. The following frames are
        handled with the GTK+ GL context. I would say this works by casuality and it could be the cause of other
        accelerated compositing issues in Wayland.

        We need to create our own GdkGLContext for the WebView, and use that in the WaylandCompositor. When the
        GdkGLContext is created, the GTK+ GL context for painting is used as a shared context, ensuring that resources
        created in the new context will be accessible from the painting one.

        Reviewed by Alex Christensen.

        As part of supporting XCBuild, update the necessary Run Script build
        phases in their Xcode projects to refer to their associated
        .xcfilelist files.

        Note that the addition of these files bumps the Xcode project version
        number to something that's Xcode 10 compatible. This change means that
        older versions of the Xcode IDE can't read these projects. Nor can it
        fully load workspaces that refer to these projects (the updated
        projects are shown as non-expandable placeholders). `xcodebuild` can
        still build these projects; it's just that the IDE can't open them.

        Make special accommodations for incorporating .xcfilelists from
        WebKitAdditions.

        When doing a client side redirect from origin A to origin B, we would swap process and
        create a SuspendedPageProxy and save it on the source BackForwardListItem. The issue is
        that the BackForwardList is locked for such redirect so we end up updating the current
        BackForwardListItem with origin B's URL while origin A's suspended page remained on
        the item. When going to another URL in the same origin A, we would not create a suspended
        page since no process-swap would occur. When pressing the back button, we would go back
        to the previous BackForwardListItem and use its SuspendedPageProxy, which is for the
        wrong URL (The pre-client redirect one).

        To address the issue, we no longer create a SuspendedPageProxy for cross-site client side
        redirects. There will be no way no go back to this suspended page anyway since the
        back/forward list item will be updated with the redirection URL.

        ProvisionalPageProxy used to forward the RegisterWebProcessAccessibilityToken IPC from
        the provisional WebProcess to the WebPageProxy right away. This in turn would notify
        the PageClient whose logic would rely on WebPageProxy::process(), which returns the
        committed process instead of the provisional one.

        To address the issue, the ProvisionalPageProxy now stores the token sent by the
        provisional WebProcess and we only call registerWebProcessAccessibilityToken()
        on the WebPageProxy *after* we've swapped to the provisional process.

        within the WebsiteDataStore as one client instance should have only one and it should live

        the navigation state. If a request meets some requirements, it will then fetch the request
        from its own cache. Once the fetch succeeds, the original load will be ignored and the
        optimizer will display the cached content.

        Web Automation: add support for simulating single touches to Automation.performInteractionSequence
        https://bugs.webkit.org/show_bug.cgi?id=193852
        <rdar://problem/28360781>

        Reviewed by Joseph Pecoraro and Simon Fraser.

        This patch makes it possible to simulate touches via the Actions API. The approach is to
        use a stripped down version of HIDEventGenerator to send HID events to the UIWindow.
        The initial version supports a single touch point; this may be expanded if needed, but
        so far it hasn't been an impediment when running desktop-oriented WebDriver test suites.

        As part of implementing this support, I went through and added [somewhat obnoxious] ENABLE()
        guards so that we don't mistakenly compile mouse support on iOS and touch on Mac,
        and vice versa. Each of the interaction methods---touch, mouse, keyboard---can be independently
        compiled out. If none is supported (i.e., Windows), then we don't even try to compile
        platformSimulate*Interaction methods or SimulatedInputDispatcher. This allows WebAutomationSession
        to not include members and code that are never going to be used on a particular platform.

        This functionality is covered by existing WebDriver test suites that use Element Click command.
        Additional tests that explicitly include 'touch' pointerType will be submitted to WPT later.

        Nearly all WebDriver tests in the wild will be requesting a 'mouse' pointerType,
        so this is necessary for compatibility. It's easier to shim at this level than try
        to implement platformSimulateMouseInteraction for iOS because

        Support for XCBuild includes specifying inputs and outputs to various
        Run Script build phases. These inputs and outputs are specified as
        .xcfilelist files. Once created, these .xcfilelist files need to be
        kept up-to-date. In order to check that they are up-to-date or not,
        add an Xcode build step that invokes an external script that performs
        the checking. If the .xcfilelists are found to be out-of-date, update
        them, halt the build, and instruct the developer to restart the build
        with up-to-date files.

        At this time, the checking and regenerating is performed only if the
        WK_ENABLE_CHECK_XCFILELISTS environment variable is set to 1. People
        who want to use this facility can set this variable and test out the
        checking/regenerating. Once it seems like there are no egregious
        issues that upset a developer's workflow, we'll unconditionally enable

        Reviewed by Alex Christensen.

        Part of generating the .xcfilelists used as part of adopting XCBuild
        includes running `make DerivedSources.make` from a standalone script.
        It’s important for this invocation to have the same environment as
        when the actual build invokes `make DerivedSources.make`. If the
        environments are different, then the two invocations will provide
        different results. In order to get the same environment in the
        standalone script, have the script launch xcodebuild targeting the
        "Apply Configuration to XCFileLists" build target, which will then
        re-invoke our standalone script. The script is now running again, this
        time in an environment with all workspace, project, target, xcconfig
        and other environment variables established.

        The "Apply Configuration to XCFileLists" build target accomplishes
        this task via a small embedded shell script that consists only of:

            eval "${WK_SUBLAUNCH_SCRIPT_PARAMETERS[@]}"

        The process that invokes "Apply Configuration to XCFileLists" first
        sets WK_SUBLAUNCH_SCRIPT_PARAMETERS to an array of commands to be
        evaluated and exports it into the shell environment. When xcodebuild
        is invoked, it inherits the value of this variable and can `eval` the
        contents of that variable. Our external standalone script can then set
        WK_SUBLAUNCH_SCRIPT_PARAMETERS to the path to itself, along with a set
        of command-line parameters needed to restart itself in the appropriate
        state.

        XCBuild changes the way xcconfig variables are evaluated. In short,
        all config file assignments are now considered in part of the
        evaluation. When using the new build system and an .xcconfig file
        contains multiple assignments of the same build setting:

        - Later assignments using $(inherited) will inherit from earlier
          assignments in the xcconfig file.
        - Later assignments not using $(inherited) will take precedence over
          earlier assignments. An assignment to a more general setting will
          mask an earlier assignment to a less general setting. For example,
          an assignment without a condition ('FOO = bar') will completely mask
          an earlier assignment with a condition ('FOO[sdk=macos*] = quux').

        This affects some of our .xcconfig files, in that sometimes platform-
        or sdk-specific definitions appear before the general definitions.
        Under the new evaluations rules, the general definitions alway take
        effect because they always overwrite the more-specific definitions. The
        solution is to swap the order, so that the general definitions are
        established first, and then conditionally overwritten by the
        more-specific definitions.

        WKWebView.goBack should reload if there is a safe browsing warning
        https://bugs.webkit.org/show_bug.cgi?id=193805

        Reviewed by Geoff Garen.

        If a WKWebView is showing a safe browsing warning and the user clicks a back button
        in the app which calls WKWebView.goBack, the WKWebView is in a state where it has not navigated yet,
        so actually going back will appear to the user to go back twice.  We can't just do nothing because the
        app is in a state where it is expecting a navigation to happen.  Reloading achieves what the user expects
        and makes the app work like the app expects.

        Regression(PSON) Back/Forward list items' URL sometimes gets replaced with the URL of a subframe
        https://bugs.webkit.org/show_bug.cgi?id=193761
        <rdar://problem/47456405>

        Reviewed by Alex Christensen.

        When doing a history navigation cross-process, the UIProcess would first send the back/forward list items
        to the destination WebProcess via WebPage::updateBackForwardListForReattach(), then ask the process to
        navigate to the expected back/forward list item.

        WebPage::updateBackForwardListForReattach() would call restoreSessionInternal(), which would call
        toHistoryItem() on each BackForwardListItem. This may end up creating more than one HistoryItem for each
        BackForwardListItem because HistoryItems are part of a tree (each frame has its own list of history items).

        Note that BackForwardListItems and HistoryItem share a BackForwardItemIdentifier which is a
        (processIdentifier, itemIdentifier) pair. We normally generate the HistoryItem's identifier from inside
        its constructor like so:
        `{ Process::identifier(), generateObjectIdentifier<BackForwardItemIdentifier::ItemIdentifierType>() }`

        However, when calling updateBackForwardListForReattach() and constructing children HistoryItem,
        applyFrameState() would generate the identifier by itself and passing it to the HistoryItem constructor.
        Its genegates the ID the exact same way so this would in theory not be a problem. Unfortunately, both
        calls to generateObjectIdentifier() get inlined and both call sites end up with their own static counter
        to generate ids. As a result, we may end up with conflicts as HistoryItems for child frames (restored
        by restoreSessionInternal()) can end up with the same identifier as HistoryItems for top frames.

        This confusion would lead to the WebContent process sending the UIProcess bad information and the URL
        of subframes could end up as the WebBackForwardListItem's mainframe URL.

        * WebProcess/WebCoreSupport/SessionStateConversion.cpp:
        (WebKit::applyFrameState):
        Stop calling generateObjectIdentifier() explicitly and let the HistoryItem constructor take care of it.
        Calling generateObjectIdentifier() for the same type from different places is not safe due to inlining.

        Create "frame hosting" nodes for the scrolling tree
        https://bugs.webkit.org/show_bug.cgi?id=193753

        Reviewed by Antti Koivisto.

        When the scrolling tree crosses frame boundaries, mutations in the parent frame currently
        require the iframe's scrolling node to get reparented in a new ancestor, which requires
        a layer tree walk of the parent frame. This is error-prone, and not very future-proof.

        Fix this by introducing "frame hosting" scrolling tree nodes. These are mostly inert
        nodes that are owned by the RenderIFrame's layer backing in the parent frame, and exist
        to provide a consistent parent node for the subframe's scrolling node.

        This patch adds the node types, but does not instantiate them yet.

        Deprecate API to limit the maximum number of WebProcesses and make it a no-op. It adds
        complexity and is not safe (conflicts with PSON).

        Add a new usesSingleWebProcess SPI to _WKProcessPoolConfiguration to be used by
        Minibrowser / Safari in order to disable process per tab (can be useful for debugging).
        Note that enabling the single WebProcess mode will disable PSON and process prewarming.

        Switch NetworkStorageSession portions of ResourceLoadStatistics to Async message passing style
        https://bugs.webkit.org/show_bug.cgi?id=193659
        <rdar://problem/47433290>

        Reviewed by Alex Christensen.

        Change the implementations of ResourceLoadStatistics code in NetworkStorageSession to use the
        'sendWithAsyncReply' so that more of the code is autogenerated. This should make test runs more
        consistent, and should reduce the possibility of bookkeeping errors in the message handling
        implementations.

        Fix the implementation of NetworkProcessProxy::clearCallbackStates to remove the manually constructed
        (and incomplete) message callbacks. These errors are a big reason to move to the auto-generated
        'sendWithAsyncReply' implementatoin. Ditto for NetworkProcessProxy::didClose.

        This patch also moves an initializaton call (WebsiteDataStore::didCreateNetworkProcess) from
        'ensureNetworkProcess' to 'processDidFinishLaunching'. In current code, the call happens before
        a connection is established to the network process, causing initialization messages to get dropped
        leading to test system flakiness.

        Finally: The WK API test code was updated to ensure that completion handlers are always called, even
        when built without ENABLE_RESOURCE_LOAD_STATISTICS defined.

        Reviewed by Alex Christensen.

        r240178 made sure that userScripts / scriptMessageHandlers / contentExtensions are always
        properly populated in the WebPageCreationParameters. This was needed in case we need to
        reconstruct the WebUserContentController on the WebProcess side. However, this caused a
        regression in the case we reuse a process where the WebUserContentController still exists
        (because it was kept alive, e.g. by the WebPageGroup). In that case, we would add duplicate
        entries to the existing WebUserContentController instance because its "add" methods did not
        have duplicate checks. To address the issue, this patch adds duplicate checks to the
        WebUserContentController "add" methods.

        If the google page is scrolled, there is sometimes a short flash.

        When restoring the page state we also restore exposedContentRect which is used to determine
        which part of the page to create layers for. Scroll position is restored by the UI process
        later so we rely on this to get the right layers for the initial view update.

        A viewport configuration update may sometimes trample over the restored exposedContentRect,
        moving it to top left. In this case the initial layer tree unfreeze commit may not have
        layers to cover the actual visible view position.

        CSSOM View specification). WebKit developers writing tests can use document.scrollingElement
        for that purpose, so that they work independently of whether the option is enabled.

        The new ResourceLoadStatistics section of 'removeData' was incrementing the
        pending callback count before deciding whether to send a message to delete
        data. This left the count out-of-balance leading to the operation never
        completing.

        This patch also prevents sending a second message to the NetworkProcess
        requesting data be deleted if the message was already sent in an earlier
        section of the method (e.g., as typically happens when all website data

        Previously I added CoordinateSystem::VisualViewport to stub out this for iOS.
        But I think that it's a mistake for safaridriver to care about VisualViewport
        being enabled or not, because it is a runtime-switchable setting.

        This patch removes CoordinateSystem::VisualViewport. Make the existing
        CoordinateSystem::LayoutViewport use visual viewport semantics if needed.

        This is tested by WebDriver element clicking tests. There should not be any
        difference in behavior until it is possible to zoom with gestures via WebDriver.

        When the WebPageProxy needs to create initialization parameters for its WebPage in the
        WebContent process, it calls WebProcessProxy::addWebUserContentControllerProxy()
        which calls WebUserContentControllerProxy::addProcess(). This last call is supposed to
        register the WebProcessProxy with the WebUserContentControllerProxy and adding the
        contentRuleLists to the WebPageCreationParameters. The issue is that if the
        WebUserContentControllerProxy already knows about this WebProcessProxy, it would return
        early and not populate the WebPageCreationParameters.

        In PSON world, when navigating back to a page that failed to enter page cache, we reuse
        the process where we previously loaded the page but re-create a new WebPage on the
        WebContent process site. When this happens, WebUserContentControllerProxy would not
        add the contentRuleLists to the WebPageCreationParameters and the new WebPage in the
        previously-suspended process would be missing them.

        Fix issues causing the scroll position to not be restored at all (or incorrectly) when
        navigating back cross-site with PSON enabled. Also make sure that the swipe gesture
        snapshot really stays up until we've restored the scroll position.

        Note that even after those changes, I can still sometimes reproduce a white flash when
        swiping back to Google search results (scroll position being correct now). This is
        tracked by <rdar://problem/47071684> and happens even if I disable PSON entirely.

        obscuredInsets is present on the HistoryItem in the WebProcess but was never passed to
        or stored by the UIProcess on the WebBackForwardListItem. obscuredInsets is needed to
        properly restore the scrollPosition (position was 70px off on my iPad without this).
        With PSON enabled, if you swipe back cross-process and the previous page was not put
        into PageCache, then the HistoryItem is gone on the WebProcess side. What happens is
        that the UIProcess sends its WebBackForwardListItem to the WebProcess, which restores
        the HistoryItem there, and then asks it to load it. The obscuredInsets was getting lost
        in the process since the UIProcess never knew about it.

        * UIProcess/Cocoa/ViewGestureController.cpp:
        (WebKit::ViewGestureController::didReachMainFrameLoadTerminalState):
        Drop logic that was causing the ViewGestureController to not wait for the scroll position
        to be restored before taking down the snapshot, when UI-side compositing is enabled.
        If you look at the comment above the code, you'll see that the code in question was meant
        to impact only the non-UI side compositing code path. As a matter of fact, when the code
        was reviewed at https://bugs.webkit.org/show_bug.cgi?id=151224, it was protected by a
        #if PLATFORM(MAC), before getting modified the wrong way before landing. In practice, we
        would have often restored the scroll position by the time the load is finished so it would
        not cause a flash in most cases. However, with PSON enabled and the layer tree freezing we
        do on process-swap, the first post-scroll restoration layer tree commit may now occur a
        little bit later and we would lose the race more often.

        * UIProcess/WebProcessProxy.cpp:
        (WebKit::WebProcessProxy::updateBackForwardItem):
        * UIProcess/WebProcessProxy.h:
        When adding PageCache support to PSON, we used to navigate the "suspended" page to
        about:blank. This would lead to unwanted WebProcessProxy::updateBackForwardItem()
        calls from the WebProcess which we wanted to ignore. We thus added logic to ignore
        updateBackForwardItem() IPC from the old WebProcess after a swap. The issue with this
        is that we sometimes miss/ignore legit updates to the HistoryItem from the old process,
        in particular with regards to the scroll position and the pageScaleFactor. So if you
        swiped and then quickly enough did a cross-site navigation, the UIProcess'
        WebBackForwardList would not get updated with the latest scroll position and we would
        thus fail to restore it later on. To address the issue, we now stop ignoring updates
        from the old WebProcess after a swap. This logic is no longer needed since we no longer
        navigate the old page to about:blank after a swap, we merely suspend it "in place".

        Some WKWebView clients might set the initial zoom scale of the page to
        something other than 1, which disables the "fast tap" behaviour.
        The fix is very simple -- just check against the initial scale rather
        than 1.

        The most likely regression from this would be pages designed for desktop,
        but provide a viewport tag saying width=device-width and initial-scale.
        They might stop allowing double-tap-to-zoom.

        Add a new SPI for controlling getUserMedia
        https://bugs.webkit.org/show_bug.cgi?id=192793

        Reviewed by Eric Carlson.

        Some weaknesses of the current getUserMedia/enumerateDevices SPI were found.
        In particular:
        - The hash salt should be handled by WebKit not by apps using WebKit.
        - No need to expose the frame URL, only the top level origin is needed.
        - The names of the callback are changed to improve the intent of these callbacks.
        Addressed these by creating a new SPI which will replace the current one.
        The current SPI will be removed later on.

        Did some refactoring by making the callbacks not return false.
        Instead, implement the default behavior inside the request objects as deny methods.
        Some further refactoring will be done as a follow-up to better align the C API with the Cocoa API.

        Pipe cache quota request from Network Process to UIProcess
        https://bugs.webkit.org/show_bug.cgi?id=193296

        Reviewed by Alex Christensen.

        When cache storage hits quota for a given origin, pipe the request back to NetworkProcess.
        No record will be put until the quota request is answered.
        The request is sent from CacheStorage::Caches to CacheStorage::Engine and to NetworkProcess.
        NetworkProcess then sends it to NetworkProcessProxy.
        Currently NetworkProcessProxy just answers by keeping the quota as it is.
        In the future, NetworkProcessProxy should make a delegate call to let the app using WebKit
        make a decision on the quota. This will allow prompting user to bump it as done for other data.

        Reviewed by Geoffrey Garen.

        The crashes would happen because loadRequestShared() would take a WebProcessProxy& in parameter but
        then call reattachToWebProcess() if the page is not valid, which would replace m_process and invalidate
        our process reference.

        To address the issue, move the reattachToWebProcess() call to loadRequest(), before calling
        loadRequestShared(). Also, update *Shared() methods to take a Ref<WebProcessProxy>&& instead
        of a WebProcessProxy& in parameter. Since we call client delegates, we need to make sure
        our process stays alive.

        Regression(PSON) View becomes blank after click a cross-site download link

        <rdar://problem/47099573>

        Reviewed by Geoffrey Garen.

        The issue tracked by rdar://problem/47099573 is that a provisional load may get
        canceled (or converted into a download) *after* we've decided to process-swap.
        In such cases, the view should keep displaying the current site and it should
        still be interactive. However, with the previous PSON model, the view (pageProxy)
        would have already swapped to the new process and would end up displaying the
        initially empty document.

        To address the issue, this patch introduces the concept of a provisional load
        in the UIProcess, handled by a ProvisionalPageProxy which has its own privisional
        process. The WebPageProxy owns the ProvisionalPageProxy but we do not commit the
        provisional page until after the load was committed in the new process. This means
        that the view / WebPageProxy keeps using the old process and displays the current
        content until a load has committed in the provisional page. If no load commits
        in the provisional process (e.g. because the load is cancelled or converted into
        a download), then we merely destroy the ProvisionalPageProxy and terminate its
        process, without impacting the WebPageProxy.

        committed in the new process.

        * Shared/WebPolicyAction.h:
        Drop Suspend policy action. At decidePolicyForNavigationAction time, in case of
        process-swap, we now tell the previous process to simply ignore the load, while
        we create a ProvisionalPageProxy to do the new load in a new process.
        Suspension of the previous page in the old process, happens later, when a load
        is actually committed in the new process.

        (WebKit::SuspendedPageProxy::~SuspendedPageProxy):
        (WebKit::SuspendedPageProxy::unsuspend):
        (WebKit::SuspendedPageProxy::didProcessRequestToSuspend):
        Unregister the SuspendedPageProxy as an IPC message receiver a little bit earlier
        when we're going to unsuspend it. This avoids conflicting with the ProvisionalPageProxy
        which tries to register itself as an IPC message receiver for the same pageID when
        a process-swap occurs and we're switching to a suspended page.

        * UIProcess/WebFrameProxy.cpp:
        (WebKit::WebFrameProxy::isMainFrame const):
        WebFrameProxy::isMainFrame() relies on checking that the frame is the WebPageProxy's m_mainFrame.
        Now that the WebPageProxy can have a ProvisionalPageProxy, also check if it is the ProvisionalPageProxy's
        m_mainFrame to maintain previous behavior.

        * UIProcess/WebPageProxy.cpp:
        (WebKit::WebPageProxy::provisionalDrawingArea const):
        Add getter for the provisional drawing area. We normally only deal with the page's current drawing area, but
        the ViewGestureController needs access to the provisional once to display the swipe gesture snapshot.

        (WebKit::WebPageProxy::swapToWebProcess):
        swapToWebProcess() no longer takes care of unsuspending the SuspendedPage because we now call swapToWebProcess()
        later, when a load is actually committed in the provisional page / process. swapToWebProcess() now also needs
        to initialize some data members such as the drawing area and the main frame as it is transferring them over from
        the ProvisionalPageProxy which started the provisional load.

        (WebKit::WebPageProxy::finishAttachingToWebProcess):
        We no longer need IsSwapFromSuspended parameter as this is called later now, after a load has actually been
        committed in the provisional process.

        (WebKit::WebPageProxy::setDrawingArea):
        (WebKit::WebPageProxy::initializeWebPage):
        - We no longer need IsSwapFromSuspended parameter as this is called later now, after a load has actually been
          committed in the provisional process.
        - Factor some code out to WebPageProxy::setDrawingArea() so that it can be shared with swapToWebProcess().

        (WebKit::WebPageProxy::maybeInitializeSandboxExtensionHandle):
        (WebKit::WebPageProxy::loadRequest):
        (WebKit::WebPageProxy::loadRequestWithNavigationShared):
        Only call setPendingAPIRequestURL() in loadRequestWithNavigation() only if ShouldTreatAsContinuingLoad is not
        Yes. This avoids hitting some assertions as this was already called during the first API call if needed.

        (WebKit::WebPageProxy::loadData):
        (WebKit::WebPageProxy::loadDataWithNavigationShared):
        (WebKit::WebPageProxy::stopLoading):
        (WebKit::WebPageProxy::reload):
        (WebKit::WebPageProxy::didPerformDragControllerAction):
        (WebKit::WebPageProxy::findPlugin):
        (WebKit::WebPageProxy::receivedNavigationPolicyDecision):
        In case of process swap, tell the previous process to ignore the load instead of suspending it right away.
        Suspension now happens later, only if we end up committing the provisional load in the new process.
        Also discard the SuspendedPage if it failed to suspend (we only reuse its process in this case). This used
        to happen a bit later but it is clearer if we do this as early as possible I think.

        (WebKit::WebPageProxy::commitProvisionalPage):
        When the load is committed in the new process, we call WebPageProxy::commitProvisionalPage(). It takes care of:
        - Actually swapping the WebPageProxy to the new process by calling processDidTerminate() / swapToWebProcess().
        - Suspending the current page.
        - Letting the client know the load is comitted
        - Destroy the ProvisionalPageProxy.
        This work used to happen earlier in continueNavigationInNewProcess().

        (WebKit::WebPageProxy::continueNavigationInNewProcess):
        Moved some of the logic to commitProvisionalPage(). We now merely start the load in a new ProvisionalPageProxy,
        without actually having the WebPageProxy switch to the new process yet.

        (WebKit::WebPageProxy::didCreateMainFrame):
        (WebKit::WebPageProxy::didCreateSubframe):
        (WebKit::WebPageProxy::didCreateWindow):
        Drop some code that is no longer needed, now that the ProvisionalPageProxy takes care of this.

        (WebKit::WebPageProxy::didDestroyNavigation):
        On process-swap, when telling the previous process to ignore the load and starting the new load in a new
        ProvisionalPageProxy, the previous WebPage attempts to destroy the navigation. In this case, we ignore
        the call since the navigation is merely taken over by the ProvisionalPageProxy.

        (WebKit::WebPageProxy::didStartProvisionalLoadForFrame):
        (WebKit::WebPageProxy::didStartProvisionalLoadForFrameShared):

        The bug was caused by the changes to unobscuredContentRectRespectingInputViewBounds not updating the visual viewport

        Also fixed the bug that VisibleContentRectUpdateInfo::operator== was not checking differences in
        unobscuredContentRectRespectingInputViewBounds which resulted in the visual viewport override not getting updated

        Regression(PSON) View becomes blank after click a cross-site download link
        https://bugs.webkit.org/show_bug.cgi?id=193361
        <rdar://problem/47099573>

        Reviewed by Geoff Garen.

        The issue tracked by rdar://problem/47099573 is that a provisional load may get
        canceled (or converted into a download) *after* we've decided to process-swap.
        In such cases, the view should keep displaying the current site and it should
        still be interactive. However, with the previous PSON model, the view (pageProxy)
        would have already swapped to the new process and would end up displaying the
        initially empty document.

        To address the issue, this patch introduces the concept of a provisional load
        in the UIProcess, handled by a ProvisionalPageProxy which has its own privisional
        process. The WebPageProxy owns the ProvisionalPageProxy but we do not commit the
        provisional page until after the load was committed in the new process. This means
        that the view / WebPageProxy keeps using the old process and displays the current
        content until a load has committed in the provisional page. If no load commits
        in the provisional process (e.g. because the load is cancelled or converted into
        a download), then we merely destroy the ProvisionalPageProxy and terminate its
        process, without impacting the WebPageProxy.

        * Shared/WebPageCreationParameters.cpp:
        (WebKit::WebPageCreationParameters::encode const):
        (WebKit::WebPageCreationParameters::decode):
        * Shared/WebPageCreationParameters.h:
        Rename isSwapFromSuspended to isProcessSwap for clarity as we always want to
        delay attaching the drawing area in case of a process-swap, no matter what
        now that the previous process is kept alive until the provisional load is
        committed in the new process.

        * Shared/WebPolicyAction.h:
        Drop Suspend policy action. At decidePolicyForNavigationAction time, in case of
        process-swap, we now tell the previous process to simply ignore the load, while
        we create a ProvisionalPageProxy to do the new load in a new process.
        Suspension of the previous page in the old process, happens later, when a load
        is actually committed in the new process.

        (WebKit::ProvisionalPageProxy::navigationID const):
        Add new ProvisionalPageProxy class to wrap the provisional load in the new process
        after a swap. The provisional page is owned by the WebPageProxy and we only commit
        the provisional page when the load is committed. Until then, the WebPageProxy keeps
        using the old process and displaying the current content.

        * UIProcess/SuspendedPageProxy.cpp:
        (WebKit::SuspendedPageProxy::~SuspendedPageProxy):
        (WebKit::SuspendedPageProxy::unsuspend):
        (WebKit::SuspendedPageProxy::didProcessRequestToSuspend):
        Unregister the SuspendedPageProxy as an IPC message receiver a little bit earlier
        when we're going to unsuspend it. This avoids conflicting with the ProvisionalPageProxy
        which tries to register itself as an IPC message receiver for the same pageID when
        a process-swap occurs and we're switching to a suspended page.

        * UIProcess/WebFrameProxy.cpp:
        (WebKit::WebFrameProxy::isMainFrame const):
        WebFrameProxy::isMainFrame() relies on checking that the frame is the WebPageProxy's m_mainFrame.
        Now that the WebPageProxy can have a ProvisionalPageProxy, also check if it is the ProvisionalPageProxy's
        m_mainFrame to maintain previous behavior.

        * UIProcess/WebPageProxy.cpp:
        (WebKit::WebPageProxy::swapToWebProcess):
        swapToWebProcess() no longer takes care of unsuspending the SuspendedPage because we now call swapToWebProcess()
        later, when a load is actually committed in the provisional page / process. swapToWebProcess() now also needs
        to initialize some data members such as the drawing area and the main frame as it is transferring them over from
        the ProvisionalPageProxy which started the provisional load.

        (WebKit::WebPageProxy::finishAttachingToWebProcess):
        We no longer need IsSwapFromSuspended parameter as this is called later now, after a load has actually been
        committed in the provisional process.

        (WebKit::WebPageProxy::initializeWebPage):
        - We no longer need IsSwapFromSuspended parameter as this is called later now, after a load has actually been
          committed in the provisional process.
        - Factor some code out to WebPageProxy::setDrawingArea() so that it can be shared with swapToWebProcess().

        (WebKit::WebPageProxy::loadRequestWithNavigation):
        Only call setPendingAPIRequestURL() in loadRequestWithNavigation() only if ShouldTreatAsContinuingLoad is not
        Yes. This avoids hitting some assertions as this was already called during the first API call if needed.

        (WebKit::WebPageProxy::receivedNavigationPolicyDecision):
        In case of process swap, tell the previous process to ignore the load instead of suspending it right away.
        Suspension now happens later, only if we end up committing the provisional load in the new process.
        Also discard the SuspendedPage if it failed to suspend (we only reuse its process in this case). This used
        to happen a bit later but it is clearer if we do this as early as possible I think.

        (WebKit::WebPageProxy::commitProvisionalPage):
        When the load is committed in the new process, we call WebPageProxy::commitProvisionalPage(). It takes care of:
        - Actually swapping the WebPageProxy to the new process by calling processDidTerminate() / swapToWebProcess().
        - Suspending the current page.
        - Letting the client know the load is comitted
        - Destroy the ProvisionalPageProxy.
        This work used to happen earlier in continueNavigationInNewProcess().

        (WebKit::WebPageProxy::continueNavigationInNewProcess):
        Moved some of the logic to commitProvisionalPage(). We now merely start the load in a new ProvisionalPageProxy,
        without actually having the WebPageProxy switch to the new process yet.

        (WebKit::WebPageProxy::didCreateMainFrame):
        (WebKit::WebPageProxy::didCreateWindow):
        Drop some code that is no longer needed, now that the ProvisionalPageProxy takes care of this.

        (WebKit::WebPageProxy::didDestroyNavigation):
        On process-swap, when telling the previous process to ignore the load and starting the new load in a new
        ProvisionalPageProxy, the previous WebPage attempts to destroy the navigation. In this case, we ignore
        the call since the navigation is merely taken over by the ProvisionalPageProxy.

        (WebKit::WebPageProxy::didStartProvisionalLoadForFrame):
        Moved some PSON logic to the ProvisionalPageProxy instead.

        (WebKit::WebPageProxy::didFailProvisionalLoadForFrame):
        When didFailProvisionalLoadForFrame() is called for a ProvisionalPageProxy, destroy it.

        (WebKit::WebPageProxy::decidePolicyForNavigationActionAsync):
        (WebKit::WebPageProxy::decidePolicyForResponse):
        Capture the process in the lambda, to make sure we send the policy decision to the same process that
        asked for it, so as to not get confused by process swaps.

        (WebKit::WebPageProxy::resetState):
        Drop some code that is no longer needed.

        (WebKit::WebPageProxy::creationParameters):
        Move the hasRegisteredServiceWorkers flag initialization from the call site to here now that we have
        more than one call site. This was just some bad factoring.

        Add utility class to temporarily override the WebPageProxy's m_process with the provisional one when

        (WebKit::WebProcessProxy::updateBackForwardItem):
        Before updating a BackForwardListItem, we normally make sure the process has a WebPageProxy with the
        item's pageID. We have to tweak the logic because there may now be no WebPageProxy with this pageID
        associated with this process yet, because it is still a ProvisionalPageProxy.

        (WebKit::WebProcessProxy::canTerminateChildProcess):
        Do not terminate the WebProcess if there are ProvisionalPageProxy objects using it.

        was presented as a new tab or new window. Add a new delegate method to query the current
        'presentation' of the browsing context. The presentation can change over time due to

        This is covered by existing WPT and internal tests. More will be added when Selenium

        Expose SPI on WKWebView for internal clients to grab information about attributes at the current selection; so
        far, this only includes whether the selection is a caret or a range, and whether or not the start of the
        selection is at the start of a new sentence.

        [iOS] Precision drop state thrashes when dragging near the top edge of an editable element
        https://bugs.webkit.org/show_bug.cgi?id=193364
        <rdar://problem/47214117>

        Reviewed by Tim Horton.

        On iOS, marking a UIDropProposal as precise offsets the hit-testing location of the drop by a small distance
        either upwards or downwards from the actual location of the user's finger. When dragging over an editable
        element, WebKit currently marks the drop proposal as precise; however, when dragging over the top edge of an
        editable element, what happens is that the hit-testing location is offset to a location outside of the editable
        element, which causes us to turn off precision drop mode; subsequently, turning off precision drop mode removes
        the offset, which causes us to hit-test within the editable element once again and re-enable precision mode, and
        the cycle continues.

        In order to mitigate this, bail out of precision drop mode when dragging near the top or bottom edges of the
        highest editable root that contains the current drop caret position (or, if the drop caret is inside of a text
        form control, use the form control as the editable element instead).

        Because gestures are very stateful, we always swap them out when swapping

        inform the client when we swap processes (only when the process actually crashes),

        on them being installed synchronously in order to find and override them.

        <rdar://problem/47158616>

        Reviewed by Alex Christensen.

        This patch modifies NetworkSession so that it owns a WebResourceLoadStatisticsStore
        object. This object is only created if the ResourceLoadStatistics feature is turned on.

        The patch also modifies WebResourceLoadStatisticsStore so that it can be constructed
        with an owning NetworkSession as an alternative to the current practice of using a
        WebsiteDataStore object.

        Two initial messages from the WebContent process are added (logFrameNavigation and
        logUserNavigation) that notify the network process of these actions. Currently they
        are called in addition the calls to the WebsiteDataStore object. These redundant calls
        will be removed in a future patch.

        This patch forces the ResourceLoadStatistics code in the NetworkSession to be off by
        default, so there should be no change in behavior with this patch.

        Reviewed by Brent Fulgham.

        This patch implements the support for U2F authenticators, and enables it for hid devices.
        It follows the CTAP spec to map WebAuthN requests to U2F commands and return the responses:
        https://fidoalliance.org/specs/fido-v2.0-id-20180227/fido-client-to-authenticator-protocol-v2.0-id-20180227.html#u2f-interoperability
        Most of the parts are done before this patch, this patch focues on: 7.2.2 and 7.3.2.

        Besides implementing the U2fHidAuthenticator, this patch also adds support in the mocking
        environment for U2F authenticators. It is done by extending the stages in MockHidConnection
        from 4 to indefinite as multi-round communications are expected to map WebAuthN requests
        to U2F requests.

        When doing the history navigation, if the source and destination history
        items are clones then we will not trigger a main frame load. We may
        however trigger loads in subframes if needed. This was an issue for the
        ViewGestureController because it was expecting a main frame load after
        calling WebPageProxy::goToBackForwardItem() in order to determine when
        taking down the view snapshot is appropriate.

        To address the problem, the ViewGestureController now takes the snapshot
        down as soon as the swipe gesture ends when the source and destination
        items are clones.

        UI process side scrollbars for UI side compositing on Mac
        https://bugs.webkit.org/show_bug.cgi?id=193106

        Reviewed by Tim Horton.

        This patch implements Mac scrollbars on UI process side using the low level NSScrollerImp/NSScrollerPairImp
        SPIs. With this patch scrollbars mostly work for the main frame and also render (but can't be interacted with)
        for the subframes.

        This is based on the similar code for web process side scrollbars in ScrollAnimatorMac. There is quite a bit of
        copy code as there is no way to share nicely. One of these will eventually go away anyway.

        Unwanted page navigation after showing & dismissing contextual menu with control-click
        https://bugs.webkit.org/show_bug.cgi?id=192912
        <rdar://problem/46318508>

        Reviewed by Timothy Hatcher.

        After the conversion to use a mouse event queue, this behavior was observed rarely, especially
        when CPU is under load and lots of things are going on in the page. In other words, it's racy.

        Based on NSEvent logging, it seems that when the system is under load, we simply take too long
        to enter the nested runloop that AppKit uses to handle events when the context menu is present.
        AppKit doesn't care whether or not the MouseDown triggered a nested runloop; on my machine it delivers
        the MouseUp event about 130ms after the MouseDown event. If we haven't show the context menu in
        that time, then the MouseUp is enqueued as a normal mouse event. If the Ctrl-click is on a link,
        then the MouseUp will be interpreted by EventHandler as a click event, which in the simplest case
        will initiate a main frame navigation. When the context menu is dismissed and the nested runloop
        is torn down, the navigation IPC message is handled in UIProcess and the page navigates away.

        We can't do much to change AppKit's inherently racy behavior, but we can avoid processing
        mouse events that are delivered whilst we are processing the context menu-initiating event.
        From the WebProcess point of view, there is no race anymore because it does not receive the
        MouseUp event.

        * UIProcess/WebPageProxy.cpp:
        (WebKit::WebPageProxy::showContextMenu):
        If new events come in, drop them on the floor. Based on testing, the nested runloop will discard
        the unpaired MouseUp event anyway, so this does not cause a change in behavior.

        Native caret shows up alongside the page's caret when requesting desktop site on jsfiddle.net
        https://bugs.webkit.org/show_bug.cgi?id=193180
        <rdar://problem/45971041>

        Reviewed by Tim Horton.

        JSFiddle uses CodeMirror; CodeMirror's editor works by capturing keystrokes and input in a hidden textarea
        element, and then drawing its own selection caret using web content. This textarea is hidden by being placed
        underneath an empty div with `overflow: hidden;`.

        When requesting desktop site on iOS, both CodeMirror's caret and the native iOS caret are shown because iOS
        selection UI consists of native views overlaid on the page, whereas on macOS, the entire textarea (along with
        the caret) are occluded by the hidden overflow container. Additionally, various iOS behaviors related to
        selection and editing, such as zooming to reveal the focused element and showing the platform callout bar, are
        active when focusing this hidden editable area; these don't work as intended, and just interfere with the page's
        custom editing UI.

        To fix this, we augment the text interaction suppression mechanism added in r238146 to detect when the focused
        element is in an empty `overflow: hidden` container, and bail out of native text editing behaviors.

        Make an additional tweak here to only stop suppressing text interaction assistant in `-_elementDidBlur` if we're
        not also in the middle of changing the focused element. Without this, focusing a hidden editable element while
        another hidden editable element is currently focused causes us to zoom to reveal the newly focused hidden
        editable element, when we should be avoiding this behavior.

        Crash under WebPageProxy::continueNavigationInNewProcess()
        https://bugs.webkit.org/show_bug.cgi?id=193113
        <rdar://problem/46938686>

        Reviewed by Brady Eidson.

        The crash was happening in continueNavigationInNewProcess() when dereferencing
        the Optional<> value returned by API::Navigation::backForwardFrameLoadType(), after verifying
        that API::Navigation::targetItem() is not null.

        When constructing an API::Navigation object with a targetItem, you HAVE to pass
        in a backForwardFrameLoadType as well so this normally is not possible. However,
        it can happen because API::Navigation::setTargetItem() can get called later on and
        set a target item on a Navigation object which potentially does not have a
        backForwardFrameLoadType. This setter was only called in one place in
        decidePolicyForNavigationAction() to update an existing Navigation object using
        the targetItem provided by a NavigationAction. This logic was added with PSON
        support.

        Because I was unable to write a test case reproducing this and because I do not know
        how it can happen in practice that we'd have a NavigationAction with a targetItem
        even though the Navigation object itself is not for a back/forward navigation, I have
        chosen to drop the unsafe API::Navigation::setTargetItem() setter and the call site.
        When the call site was added, with ProcessSwap.NavigateToDataURLThenBack API test,
        the intention was to create a back/forward navigation object instead of a standard load
        navigation one if there is currently no existing Navigation object in the UIProcess.
        This can happen when the back/forward navigation is triggered by the WebProcess via
        JS (e.g. history.back()) and this is what the API test covers. The part of the logic
        that updates an existing Navigation object with a targetItem coming from the
        NavigationAction is untested and I have no evidence it does anything useful. However,
        we DO have evidence that it can cause crashes.

        [PSON] Calling history.back() from inside the load event handler prevents process-swapping
        https://bugs.webkit.org/show_bug.cgi?id=193120

        Reviewed by Alex Christensen.

        A HistoryItem is created only *after* we've fired the load event. As a result, if you call
        history.back() in JS from inside the load event handler, the current HistoryItem and and
        the target HistoryItem will be the same. This is normally not an issue. However, there was
        logic inside of WebProcessPool::processForNavigationInternal() which would compare the
        processID of the source and destination BackForwardListItems and which would force a process
        reuse if both BackForwardListItems came from the same WebContent process. So even though
        we swapped when doing a standard load from site A to site B, we would fail to swap if site
        B called history.back() from inside its load event handler.

        To address the issue, stop relying on the source backforward item's processID. Instead, just
        use the WebContent process matching the destination backforward item's processID if it still
        exists.

        previous buttons in the input accessory view), we would compute a selection rect of `{{ 0, 0 }, { 0, 0 }}`, and
        subsequently try to scroll the focused element to the center of the visible area, without taking the selection
        rect into account.

        However, after r239441, the web process sends the element interaction location to the UI process, which then
        computes the selection rect by taking this location and adding a size of `{ 1, 1 }` (before r239441, this was
        done in `WebPage::getAssistedNodeInformation`). However, our new implementation doesn't take into account the
        case where the element interaction rect is null, which happens when the last interaction location is outside of
        the bounding rect of the element. In this case, we set the element interaction location to { 0, 0 } and end up
        computing a selection rect of `{{ 0, 0 }, { 1, 1 }}` instead of `{{ 0, 0 }, { 0, 0 }}` as we would have
        previously done. This causes us to scroll up to the origin, instead of revealing the focused element.

        To fix this, we restore the pre-r239441 behavior. See additional comments below for details.

        * Shared/FocusedElementInformation.h:

        Rename `elementInteractionLocation` to `lastInteractionLocation`. This was previously
        `elementInteractionLocation` due to existing logic that tries to move the interaction location into the bounding
        rect of the element in the case where visual viewports are disabled; however, since this feature has long been
        enabled by default for all modern WebKit clients (internal and external), it's simpler to just use always send
        the last interaction location over to the UI process, and have the UI process use `{{ 0, 0 }, { 0, 0 }}` if
        the interaction location is outside of the element rect.

        In the very unlikely event that any modern WebKit client disables visual viewports, this will still behave
        reasonably, since we'll just use `{{ 0, 0 }, { 0, 0 }}` as the target rect and scroll to reveal the entire
        element rather than the top left corner of the element.

        Move the check for whether the interaction location is inside the element's bounding rect from the web process
        to the UI process. This relocates the logic to determine whether the selection rect should be a 1 by 1 fallback
        interaction rect or the zero rect (`{{ 0, 0 }, { 0, 0 }}`) closer to the code that actually uses this rect.

        REGRESSION (r239441): [iOS] Selection UI sometimes doesn't change after tapping "select all" in the callout bar
        https://bugs.webkit.org/show_bug.cgi?id=193070
        <rdar://problem/46921508>

        Reviewed by Tim Horton.

        r239441 added logic to include an EditorState in the next layer tree commit when refocusing an element; this was
        done to ensure that after tapping an element that has already been programmatically focused, we still send up-
        to-date editor information to the UI process for the purposes of zooming to the selection rect, even if the
        selection in the DOM is unchanged, since other aspects of the editor state may have changed since the element
        was initially focused.

        We currently try to flag the next layer tree commit by setting `m_hasPendingEditorStateUpdate` to `true`.
        However, this is problematic since we aren't guaranteed in all cases that a compositing flush has been
        scheduled. In the case where it hasn't, we'll end up in a state where the editor state update flag has been set,
        yet the update will not make it over to the UI process until something happens that forces a layer tree commit
        (e.g. scrolling, pinch zooming). Worse still, if the selection is then programmatically changed from the web
        process, we will bail from sending a subsequent editor state update to the UI process because `WebPage` thinks
        that a pending editor state has already been scheduled. This manifests in selection UI not updating after
        tapping "Select All" in the callout bar, if the callout bar was brought up by tapping near the selection (since
        this refocuses the element).

        To fix this, we adjust this logic in `WebPage::elementDidRefocus` so that it sets the flag and then schedules a
        compositing flush, but only if the user is actually interacting with the focused element (i.e., if the page
        calls `focus` repeatedly, we won't continue to schedule compositing flushes).

        Add a private helper method to schedule an editor state update by setting `m_hasPendingEditorStateUpdate` to
        `true` and then scheduling a compositing layer flush. Also, add a FIXME aluding to the fact that scheduling an
        entire compositing layer flush to send an editor state update is somewhat wasteful, and should be replaced by
        just scheduling this work to be done before the next frame (see: <rdar://problem/36523583> for more detail).

        We also use this helper method in a few places where we currently turn on the editor state flag and schedule a
        subsequent compositing flush.

        Reviewed by Tim Horton.

        In r238146, I added a mechanism to detect when the selection is hidden within transparent editable elements, and
        used this to suppress native selection on iOS (such as selection handles, highlight, callout bar, etc.) to avoid
        conflicts between the page's editing UI and the platform.

        However, one additional technique observed on some websites involves hiding the selection by moving it into a
        tiny (1x1) editable element. Here, we currently still present a callout bar with editing actions, as well as
        show a selection caret or handles on iOS. To fix this, we extend the mechanism added in r238146 by also
        suppressing the selection assistant in the case where the editable element's area is beneath a tiny minimum
        threshold.

        Rename selectionClipRect to focusedElementRect. We currently propagate the bounds of the focused element to the
        UI process through EditorState updates, but only for the purpose of returning it in the computed selection clip
        rect; instead, rename this member to something more general-purpose, so we can also use it when determining
        whether to suppress the selection assistant.

        [GTK][WPE] Add DeviceIdHashSaltStorage disk persistence
        https://bugs.webkit.org/show_bug.cgi?id=190466

        Reviewed by Youenn Fablet.

        Added persistency to the DeviceIdHashSaltStorage. Implemented a
        decoder and an encoder for the HashSaltForOrigin struct to store
        it in a file, this allows us to save the lastTimeUsed, the origin
        and the hash salt. It uses a new directory where it creates a file
        per hash salt, the name of the file is the hash salt to avoid
        leaking information in the system. The last time used and the
        origin are stored inside the file, it also adds a version
        directory used to change the structure of the file in the future,
        if we need to do it. In the DeviceIdHashSaltStorage class the disk
        operations happen in a WorkQueue, but all interactions go in the
        main thread. We added code to handle the operations when the load
        still did not finish.

        Reviewed by Chris Dumez.

        There are a number of reported bugs that are difficult or impossible
        to track down with our current level of logging. Additionally, some
        software groups lower in the page-loading stack have requested logging
        sufficient for tracking a user-visible error message down to the
        requested resource that caused the message. Add more-comprehensive
        logging to address these issues/requests.

        [iOS] Replace "node assistance" terminology in WebKit with "focused element"
        https://bugs.webkit.org/show_bug.cgi?id=192936

        Reviewed by Tim Horton.

        Renames a few methods and data structures in WebKit, to refer to "focused elements" rather than "assisted nodes";
        see below for more details. No new tests, because there should be no change in behavior.

        * Shared/FocusedElementInformation.cpp: Renamed from Source/WebKit/Shared/AssistedNodeInformation.cpp.

        (WebKit::FocusedElementInformation::encode const):
        (WebKit::FocusedElementInformation::decode):
        * Shared/FocusedElementInformation.h: Renamed from Source/WebKit/Shared/AssistedNodeInformation.h.

        Rename AssistedNodeInformation to FocusedElementInformation. Additionally, introduce a named type for the
        focusedElementIdentifier (which is currently just a `uint64_t`).

        [iOS] Focusing an editable element should scroll to reveal the selection
        https://bugs.webkit.org/show_bug.cgi?id=192802
        <rdar://problem/46781759>

        Reviewed by Tim Horton.

        Currently, when tapping on an editable element, logic in -[WKWebView _zoomToFocusRect:…:] attempts to adjust the
        visible viewport such that the rect containing the selection is visible. However, AssistedNodeInformation's
        selectionRect is used here, which (as the FIXME in WebPage::getAssistedNodeInformation notes) is either the last
        touch location, or the top left of the element if the touch location is outside of the element's bounding rect.
        This leads to confusing and undesirable behavior when tapping near the bottom of a large contenteditable element
        to focus it, since the actual selection will end up near the top of the element, yet we'll try to scroll to
        reveal the bottom of the element, which causes the visible selection to scroll offscreen. Notably, this affects
        scenarios involving editable web views embedded in apps, such as Mail compose.

        Right now, we use the last touch location as an approximation for the selection rect because the selection may
        have not yet been updated at the moment when focus moves into an editable element. To fix this, we defer the
        process of zooming to the focused element rect until after the selection changes and the UI process is updated
        with information about the new selection rects.

        Test: editing/selection/ios/selection-is-visible-after-focusing-editable-area.html

        (WebKit::AssistedNodeInformation::encode const):
        (WebKit::AssistedNodeInformation::decode):
        * Shared/AssistedNodeInformation.h:

        Rename selectionRect to elementInteractionLocation, to more accurately reflect its value and purpose. This isn't
        strictly always the last touch location, since we may default to the focused element location instead if the
        last touch location is outside of the element rect.

        * UIProcess/API/Cocoa/WKWebView.mm:
        (-[WKWebView _zoomToFocusRect:selectionRect:insideFixed:fontSize:minimumScale:maximumScale:allowScaling:forceScroll:]):

        Tweak a constant that determines the minimum amount of margin to leave between the selection rect and the edge
        of the window when scrolling to reveal the focused element. Previously, this was larger than necessary to
        accomodate for the fact that the "selection rect" used when zooming to the focused element did not take the
        actual selection into account at all, and was simply a 1 by 1 rect; this meant that the margin needed to be
        large enough to exceed the usual height of a text caret in editable content. Since we now use the real selection
        rect, we can be much less generous with this margin.

        Don't additionally update the selection in the middle of triggering zooming to the focused element; on
        particular versions of iOS, this now attempts to scroll the selection rect on-screen, which then conflicts with
        zooming to reveal the focused element.

        (-[WKContentView _zoomToRevealFocusedElement]):

        Renamed from _displayFormNodeInputView to _zoomToRevealFocusedElement, to make the purpose of this function more
        clear. Additionally, pull logic to update the accessory view out of this method, so that it's strictly concerned
        with zooming to the focused element.

        (-[WKContentView inputView]):

        Add a FIXME describing the implications of zooming to the focused element in the implementation of -inputView.

        (-[WKContentView accessoryTab:]):

        Fix a subtle issue when keeping track of _didAccessoryTabInitiateFocus. Currently, this is set to YES in
        -accessoryTab: and unset in _displayFormNodeInputView, but since _displayFormNodeInputView may be invoked
        multiple times for the same focused element (see: -inputView), we might end up zooming to the focused element
        with _didAccessoryTabInitiateFocus set to NO, even though we initiated focus with the previous/next buttons.

        Instead, temporarily set a different ivar, _isChangingFocusUsingAccessoryTab, to YES in -accessoryTab:, and
        unset it in the completion handler after the focused element has changed. Then, when we _startAssistingNode:,
        set _didAccessoryTabInitiateFocus to _isChangingFocusUsingAccessoryTab. This ensures that the correctness of
        _didAccessoryTabInitiateFocus isn't tied to the number of times -[WKContentView inputView] is invoked when
        focusing an element.

        need to be cleared immediately, and we still need to clear the warning immediately if the user has said to go back.

        r239337 exposed a subtle issue in the implementation of `-[WKDataListSuggestionsView updateWithInformation:]`,
        wherein we might end up recomputing information for table view cells at rows that no longer exist. This currently
        happens because we first set the datalist's `_suggestions`, then change the table view's frame, and then finally
        reload the table view; however, in the case where the number of suggestions decreased and the frame changed
        (which prompts AppKit to ask us again for table cell views), we'll attempt to access an out-of-bounds index in
        the `_suggestions` vector.

        To address this, we change our suggestions and immediately reload the table view before updating `NSTableView`'s
        frame, so that we only provide table view cells for rows that actually correspond to items in `_suggestions`.

        Regression(r239182) SuspendedPage's process reuse for link navigation optimization sometimes broken
        https://bugs.webkit.org/show_bug.cgi?id=192772

        Reviewed by Antti Koivisto.

        With r239182, if the page in the previous process would fail to enter PageCache, we would destroy
        the corresponding SuspendedPageProxy, which would potentially terminate the process. This would
        regress performance when trying to navigate back in history to that page. This would also regress
        performance when link-navigating to the same domain as we would have previously reused the suspended
        page's process for such navigation.

        Address the issue by keeping the SuspendedPageProxy alive even if the WebPage fails to suspend.
        When trying to reuse a SuspendedPageProxy, if the page failed to suspend, reuse its process but
        not the suspended page itself.

        [iOS] Focusing a large editable element always scrolls to the top of the element
        https://bugs.webkit.org/show_bug.cgi?id=192745
        <rdar://problem/46758445>

        Reviewed by Tim Horton.

        Currently, when focusing form controls or editable elements, we try to scroll such that the focused element rect
        is centered within the visible area. In the case of very large focusable elements whose dimensions exceed the
        width or height of the visible area, we instead scroll such that the top left point of the element is at the top
        left corner of the visible area.

        However, this results in unnecessary scrolling if the top of the element is already near the top of the visible
        area. For WebKit2-based rich text editors that have an editable body element with a top content inset that
        contains additional content, this means we will always scroll the additional content away when focusing the
        editable body.

        To avoid this behavior, adjust focused element zooming logic for editable elements that are too large to be
        centered in the visible area, such that we only scroll the top left position of the focused element to the top
        half or top right of the visible area, respectively. This reduces the amount of scrolling when focusing large
        editable elements, while still making it clear which element is being focused.

        Also, fix an existing bug wherein focusable elements that are meant to be centered within the visible area are
        currently offset by half the difference between the bottom inset amount and the top inset amount, in the case
        where the `_obscuredInsets` SPI is used to specify content insets for the web view (i.e., MobileSafari).

        This unifies SharedMemory so in the following way, across platforms:

        - SharedMemory::create() is removed, to avoid ambiguity.
        - SharedMemory::allocate() always allocates a new block of shared memory.
        - SharedMemory::wrapMap() always creates a SharedMemory object which refers to an
          existing region of memory resulting from memory-mapping a file.

        [PSON] We should not need to navigate to 'about:blank' to suspend pages
        https://bugs.webkit.org/show_bug.cgi?id=192668
        <rdar://problem/46701466>

        Reviewed by Alex Christensen.

        To support PageCache when process-swap on cross-site navigation is enabled,
        we've been navigating the previous process to 'about:blank' when swapping.
        This would trigger PageCaching of the page in the old process. While
        convenient, this design has led to a lot of bugs because we did not really
        want a navigation to happen in the old process.

        To address the issue, when a WebPage is asked to suspend (for process-swap),
        we now attempt to add it to PageCache and save it on the current HistoryItem,
        *without* triggering any navigation. Any pending navigation gets cancelled
        and we just suspend in place.

        Later on, when we want to go back to this HistoryItem, we simply leverage the
        existing WebPage::goToBackForwardItem() code path. The only subtlety is that
        we're actually asking the WebPage to load a HistoryItem that is the current
        one in the History. I had to tweak a some logic / assertions to support this
        as this is not something we usually do. However, it actually works with very
        little changes and successfully restores the PageCache entry on the current
        HistoryItem.

        There is no expected overall behavior change and ProcessSwap API tests (which
        cover PageCache) still pass. This is merely a simpler design because it avoids
        navigating to about:blank.

        Instead of nullifying the manager, make it a UniqueRef and clear it on closing the page.
        This ensures we revoke the sandbox extensions as early as possible and keep the manager lifetime simple.

        Reviewed by Geoff Garen.

        WatchOS has a few special requirements:
        1. The margin size needs to be smaller and the title font smaller to fit on the screen.
        2. The exclamation point cannot be beside the title or it won't fit on the screen.  I put it above the title.
        3. The application must be told when the safe browsing warning has been shown.  I added a new delegate callback.
        4. The UIScrollView's contentSize must be set even before the details are shown to be able to scroll down to the buttons.
           This was already an issue on small WKWebViews on iOS, so this fixes both operating systems.

        PSON logic gets confused by concurrent decidePolicyForNavigationAction requests
        https://bugs.webkit.org/show_bug.cgi?id=192482
        <rdar://problem/46470145>

        Reviewed by Antti Koivisto.

        It is possible to get 2 parallel decidePolicyForNavigationAction() requests from the
        WebProcess when a new load is started before responding to the existing policy
        decision. This would lead to several issues with regards to PSON:
        - We would decide to swap for the first policy decision and tell the WebProcess to
          suspend. However, because the WebProcess issued a new decidePolicyForNavigationAction
          since for the same frame, the previous one is invalidated and the WebProcess would
          ignore our request to suspend.
        - We would hit assertions later on because the navigation has been destroyed and yet
          we're getting a didStartProvisionalLoad for it.
        - swapToWebProcess() was asynchronous so that it would wait for the destination
          SuspendedPage to finish suspending before asking it to unsuspend. This led to various
          problems because anything can happen in the UIProcess while we're waiting for the
          suspension (e.g. another load). Also, we may create the SuspendedPageProxy for
          the current page too late and start getting IPC from the previous process about
          the suspension load to about:blank.

        To address these issues, the following design is now implemented:
        - swapToWebProcess() is no longer asynchronous
        - instead, WebProcessPool::processForNavigation() is now asynchronous. This is better
          because at this point we have not yet told the WebProcess about the policy decision.
          We already properly deal with the policy decision being made asynchronously. This
          also allows us to choose another process if the SuspendedPage we'd like to use
          failed to suspend.
        - If the WebProcess receives a PolicyAction::Suspend but ignores it, have it send an
          IPC to the UIProcess so that the SuspendedPageProxy knows about it. We then destroy
          the SuspendedPageProxy and make sure it is not used.
        - After the asynchronous process selection, if the navigation has been destroy, abort
          the process-swap to avoid hitting assertions later on due to doing a load for a
          destroyed navigation.

        * UIProcess/SuspendedPageProxy.cpp:
        (WebKit::SuspendedPageProxy::~SuspendedPageProxy):
        Make sure m_whenReadyToConsume completion handler gets called if necessary if the
        SuspendedPageProxy gets destroyed. We pass null so that the SuspendedPage is not
        used.

        (WebKit::SuspendedPageProxy::whenReadyToConsume):
        Add whenReadyToConsume() utility method to get a completion handler called when
        the SuspendedPageProxy is ready to be used. This basically means we have to wait
        for the page to finish its about:blank suspension load. If the suspension fails
        then we call the completion handler with null to indicate that the suspended
        page is not usable.

        (WebKit::SuspendedPageProxy::unsuspendAndConsume):
        Rename unsuspend() to unsuspendAndConsume() and make it synchronous. This only gets
        called after whenReadyToConsume()'s completion handler has been called and if we
        do decide to use the SuspendedPageProxy. It tells the WebProcess to unsuspend and
        removes the SuspendedPageProxy from the WebProcessPool.

        (WebKit::SuspendedPageProxy::didFinishLoad):
        rename m_finishedSuspendingHandler to m_whenReadyToConsume.

        (WebKit::SuspendedPageProxy::didFailToSuspend):
        Add new didFailToSuspend() that gets called when the WebProcess sends us an IPC telling
        us it ignored our request to suspend. We then call m_whenReadyToConsume completion
        handler with null and destroy the SuspendedPageProxy.

        Deal with WebProcessPool::processForNavigation() now being asynchronous.

        (WebKit::WebPageProxy::continueNavigationInNewProcess):

        whenReadyToConsume() on it to wait for it to suspend. If the SuspendedPageProxy
        fails to suspend use a new process instead.

        * WebProcess/WebPage/WebFrame.cpp:
        (WebKit::WebFrame::didReceivePolicyDecision):
        If we ignore the policy decision and the decision was "Suspend", send the DidFailToSuspendAfterProcessSwap

        They're usually next to each other, but in narrow WKWebViews they currently get clipped.
        In order to make it more likely that both buttons are completely visible, put one above
        the other if the WKWebView is too narrow to completely show both.  This also helps with
        languages where the translations of "Go Back" or "Show Details" are rendered wider than English.

        [iOS] Caret is obscured by finger when dragging over an editable element

        Reviewed by Tim Horton.

        Add support for setting the `precise` property of `UIDropProposal` to YES when dragging over an editable area.
        When enabled, this property shifts the drop location up by a small amount, allowing the user to see the drop
        caret (currently, this is not the case, and it's difficult to drop text at a precise location on iOS). Changes
        are covered by adding to existing API tests.

        Add a new version of `-_webView:willUpdateDataInteractionOperationToOperation:forSession:` that receives and
        returns a UIDropProposal, so that Mail can more easily port over existing logic in its legacy-WebKit-based
        compose implementation. iOS Safari is currently the only client of this private delegate, so the old version can
        be easily removed once Safari adopts this new version.

        Move capture manager from RealtimeMediaSourceCenter to capture factory
        https://bugs.webkit.org/show_bug.cgi?id=192542

        Reviewed by Eric Carlson.

        Make sure to unregister for video capture as done for other capture types.
        Implement manager which should be doing nothing as the manager is used for enumeration of devices
        which should only happen in UIProcess.

        Given that mock capture is interfering with UserMediaCaptureManager,
        switching on/off mock capture will require creating a new process.
        This shortcoming should be fixed once mock capture will be fully happening in
        the same process as regular capture.

        <rdar://problem/46506286>

        Reviewed by Alex Christensen.

        This patch makes it so that we can use HTTP/HTTPS proxies on iOS as well.
        To enable on iOS, you can do something like:
        $ defaults write -g WebKit2HTTPProxy -string "http://localhost:8080"
        $ defaults write -g WebKit2HTTPSProxy -string "http://localhost:8080"
        
        This patch also changes the Proxy to be enabled on a per NSURLSession
        basis instead of a per process basis.

        Fix the crash by ensuring that the result of `-renderedDrawing` survives long enough to be wrapped by a
        `RetainPtr` in `-PNGRepresentation`. This isn't currently testable, since this codepath isn't supported on the
        iOS simulator; instead, I manually verified using MobileAttachments.app.

        Also, instead of notifying the Web Content process when a service is picked

        [iOS] WKWebView should match UITextView behavior when editing text with an RTL keyboard
        https://bugs.webkit.org/show_bug.cgi?id=187554
        <rdar://problem/42075638>

        Reviewed by Tim Horton.

        Add support for automatically switching the base writing direction to the default writing direction with respect
        to the current keyboard in an editable WKWebView by implementing `-setBaseWritingDirection:forRange:`. On iOS 12
        and earlier, UIKit invokes this protocol method whenever the keyboard is changed to one with a different writing
        direction, although in some other versions of iOS, this only happens when first focusing an editable area.

        Regression(r238817) PSON Page Cache API tests are failing
        https://bugs.webkit.org/show_bug.cgi?id=192348

        Reviewed by Alex Christensen.

        Before suspending a WebProcess on iOS, we normally fake a memory pressure signal
        so that the suspended process uses as little memory as possible while suspended.
        Among other things, this will clear the page cache. This is an issue in the case
        of process-swap on navigation because we keep suspended web processes around to
        keep Page Cache functional.

        To address the issue, when a WebProcess is about to get suspended, we check if
        the process has any suspended WebPage (WebPage used for PSON PageCache support)
        and we bypass the PageCache clearing if it does.

        Our API tests did not catch this before r238817 because the NavigationState's
        assertion was preventing the old WebProcesses from suspending for 3 seconds,
        which was enough for those tests to complete.

        Reviewed by Alex Christensen.

        In WebPageProxy::swapToWebProcess(), we would call removeWebPage() on the old WebProcessProxy and then
        addExistingWebPage() on the new WebProcessProxy, as you would expect in case of process swap.

        The issue is that WebProcessProxy::removeWebPage() calls WebProcessPool::pageEndUsingWebsiteDataStore()
        which would cause the session to get destroyed assuming this was the last page using it. We would
        therefore lose session cookies after a process-swap in private session.

        To address the issue, a parameter to WebProcessPool::pageEndUsingWebsiteDataStore() and
        WebProcessPool::pageBeginUsingWebsiteDataStore() to control if we want to tell the WebProcessPool
        about the page beginning / ending its use of the session. In the case of a process-swap, we make
        sure the process pool is not notified.

        If the client forces a process-swap, we should process-swap, even if the browsing
        context has an opener (or openees). Previously, we would only bypass the cross-site
        check, not the openee / openees checks.

        The issue when doing so is that the openee still has a opener link to the window
        in the old process. They would see that the window is still there and navigated
        to 'about:blank' due to our page suspension logic. To address the issue, we no
        longer suspend the old WebPage if the process swap was forced by the client and
        we make sure that the old WebPage gets closed.

        while we're in the 'paused' state, and drop it on the floor. That would
        then mean that we time out instead of promptly removing the snapshot.

        If the previous WebProcess had a ProcessAssertion to prevent it from being suspended,
        after navigation and process swapping we need the new WebProcess to update its process assertions.

        A key down event may be associated with a key command. If it is then we want to execute the

        Some clients strongly depend on there being some data in an image, even if
        it's not of a usable size yet. We'll invalidate the attachment when the
        canvas size changes, so it will eventually settle at a usable size (after
        the first layer tree commit that includes the editable image).

        REGRESSION (r238635): Dragging a text selection within WKWebView causes the selection highlight to get into a bad state
        https://bugs.webkit.org/show_bug.cgi?id=192165
        <rdar://problem/46346682>

        Reviewed by Daniel Bates.

        Fixes a bug in PageClientImpl::isViewFocused. Consider the following scenario:
        1. WKWebView is hosted within the view hierarchy
        2. First responder is *not* WKContentView
        3. The active focus retain count is nonzero

        Before r238635, we would return true, due to condition (3). However, after r238635, we only consider whether the
        first responder is WKContentView, since the web view is in the view hierarchy. This breaks scenarios where
        WebKit or UIKit attempts to retain focus and later restore the content view to be the first responder (an
        example of this is dragging a text selection between editable elements in the same web view).

        To fix this, simply bail early and return true if focus is being retained.

        Make it possible for clients to allow other processes to monitor the state of active
        downloads. On Cocoa platforms, this can be done by creating an NSProgress, publishing
        it on an appropriate file URL (potentially a different file URL than where the download
        data is being written), updating properties on it as the download makes progress, and
        wiring up a cancellation handler that allows it to be remotely canceled. Interested

        Update generate-{derived,unified}-sources scripts to support generating .xcfilelist files

        Reviewed by Alex Christensen.

        The Generate Derived Sources and Generate Unified Sources build phases
        in Xcode need to have their inputs and outputs specified. This
        specification will come in the form of .xcfilelist files that will be
        attached to these build phases. There is one .xcfilelist file that
        lists the input file and one that lists the output files. As part of
        this work, the various generate-{derived,unified}-sources scripts that
        are executed in these Generate build phases are modified to help in
        the creation of these .xcfilelist files. In particular, they can now
        be invoked with command-line parameters. These parameters are then
        used to alter the normal execution of these scripts, causing them to
        produce the .xcfilelist files as opposed to actually generating the
        files that are listed in those files.

        <rdar://problem/46284301>

        Reviewed by Alex Christensen.

        In r238008, I added a facility for DerivedSources.make makefiles to
        print out the list of files that they generate. This output was used
        in the generation of .xcfilelist files used to specify the output of
        the associated Generate Derived Sources build phases in Xcode. This
        approach worked, but it meant that people would need to follow a
        specific convention to keep this mechanism working.

        Instead of continuing this approach, I'm going to implement a new
        facility based on the output of `make` when passed the -d flag (which
        prints dependency information). This new mechanism is completely
        automatic and doesn't need maintainers to follow a convention. To that
        end, remove most of the work performed in r238008 that supports the
        print_all_generated_files target.

        At the same time, it's important for the sets of targets and their
        dependencies to be complete and correct. Therefore, also include
        changes to bring those up-to-date. As part of that, you'll see
        prevalent use of a particular technique. Here's an example:

            BYTECODE_FILES = \
                Bytecodes.h \
                BytecodeIndices.h \
                BytecodeStructs.h \
                InitBytecodes.asm \
            #
            BYTECODE_FILES_PATTERNS = $(subst .,%,$(BYTECODE_FILES))

            all : $(BYTECODE_FILES)

            $(BYTECODE_FILES_PATTERNS): $(wildcard $(JavaScriptCore)/generator/*.rb) $(JavaScriptCore)/bytecode/BytecodeList.rb
                ...

        These lines indicate a set of generated files (those specified in
        BYTECODE_FILES). These files are generated by the BytecodeList.rb
        tool. But, as opposed to the normal rule where a single foo.output is
        generated by foo.input plus some additional dependencies, this rule
        produces multiple output files from a tool whose connection to the
        output files is not immediately clear. A special approach is needed
        where a single rule produces multiple output files. The normal way to
        implement this is to use an .INTERMEDIATE target. However, we used
        this approach in the past and ran into a problem with it, addressing
        it with an alternate approach in r210507. The above example shows this
        approach. The .'s in the list of target files are replaced with %'s,
        and the result is used as the left side of the dependency rule.

        This means that jamming a '#' right in front of the first character of
        a message definition (as opposed to the beginning of a line) will have
        no effect and the line will get treated just the same as a

        Fixes an issue where pressing Command + Down Arrow does not scroll the view to the end of the page.

        Following r237738 the value of the enumerations used to identify modifier keys (e.g. Shift) changed
        to match the values of the corresponding enumerations in GraphicsServices, which are the
        enumerations UIKit uses to computes the modifier flags bitmask when instantiating a WebEvent to
        pass to WebKit. Before r237738 WebKit was using enumerations whose values matched the values
        of the corresponding UIKit public API UIKeyModifier* enumerations. For non-content editable elements,
        WebKit intercepts UIKit events in -_handleKeyUIEvent, synthesizes and dispatches its own WebEvent.
        However it was creating WebEvents with a modifier flags bitmask built from the UIKeyModifier* enumerations,
        -_modifierFlags, as opposed to a bitmask from the GraphicsServices enumerations, -_gsModifierFlags.
        Instead WebKit should call -_gsModifierFlags to compute the GraphicsServices-compatible modifier
        flags bitmask when instantiating a WebEvent.

        Reviewed by Ryosuke Niwa.

        If automatic process-prewarming is not explicitly turned on/off by the client, then we now only
        turn it on automatically after the first process swap. Previously, it was always enabled if
        process-swap on cross-site navigation was enabled (which is the case by default for all apps).

        This is important because some apps do not actually browse (only display static content) or never
        browse cross-site, and thus would not benefit from process prewarming and yet pay a memory cost.

        (WebKit::WebProcessPool::processForNavigation):
        On first process swap, if the client did not explicitly turn on or off automatic process prewarming

        [Cocoa] Make it easier to encode NSObjects
        https://bugs.webkit.org/show_bug.cgi?id=191948

        Reviewed by Dean Jackson.

        It should be easier to encode objects that conform to NSSecureCoding for WebKit IPC. Right
        now, several argument coders duplicate the logic for encoding and decoding objects using
        NSKeyedArchiver and NSKeyedUnarchiver.

        This patch adds encodeObject() and decodeObject() primitives for encoding and decoding using
        Foundation keyed archiving. It then partially specializes ArgumentCoder for raw pointers and
        RetainPtrs whose pointee conforms to NSSecureCoding to call these new primitives.

        This allows us to use Encoder::operator<< to encode raw pointers or RetainPtrs and use
        Decoder::operator>> to decode to an optional RetainPtr. By default, IPC::decode infers the
        allowed class for decoding by calling `[T class]`. We can also specify the allowed classes
        explicitly for containers and classes that are loaded at runtime.

        CompletionHandler-based async IPC messages only work when the completion handler takes a single argument
        https://bugs.webkit.org/show_bug.cgi?id=191965

        Reviewed by Tim Horton.

        Teach `messages.py` to handle the case where an async IPC completion handler takes no arguments, or takes more
        than a single argument. Currently, the generated code attempts to wrap all arguments in a `WTFMove(*~)`, but
        this either results in `WTFMove(*)` in the case where there are no arguments, or `WTFMove(*foo, *bar, *baz)` in
        the case where there are several arguments. Both of these results fail to compile.

        Instead, emit `completionHandler()` when there are no arguments, and
        `completionHandler(WTFMove(*foo), WTFMove(*bar), WTFMove(*baz))` when there are multiple arguments.

        Replace LayerOrView typedef with a class
        https://bugs.webkit.org/show_bug.cgi?id=191927

        Reviewed by Tim Horton.

        This typedef restricts remote layer representation to be either a CA layer or a view. We might want
        have more flexibility, for example tiles don't really need to be UIViews. It will also make it easier
        to unify Mac and iOS code, and hopefully make it less confusing too.

        This patch introduces RemoteLayerTreeNode class that replaces most uses of LayerOrView typedef
        (the rest are converted to pure CALayer). It also does a bunch of related cleanup.

        Regression(r238353) Load sometimes hangs when navigating back after a cross-site navigation
        https://bugs.webkit.org/show_bug.cgi?id=191914

        Reviewed by Ryosuke Niwa.

        When process-swapping on a cross-site server-side redirect, we end up doing a decidePolicyForNavigationResponse
        policy check for the about:blank suspension load. This policy decision is ignored by the UIProcess because
        SuspendedPageProxy does not handle this particular IPC message. To handle the issue, make sure the WebProcess
        never sends a DecidePolicyForNavigationResponse IPC to the UIProcess for about:blank suspension loads and let
        the load proceed.

        The issue was already there before r238353 but it was made obvious by r238353 which caused a hang when trying
        to reuse a Suspended page which is hanging while trying to suspend.

        Avoid potential longer than expected layer flush delays
        https://bugs.webkit.org/show_bug.cgi?id=191833

        Reviewed by Dean Jackson.

        Layer flush throttling also stops style recalcs and layouts. Layouts schedule layer flushes. Especially
        on a slow network we can in principle end up in situation where layer flush timer fires but there is no
        flush scheduled and so nothing happens. However there is a pending style recalc or layout that would
        actually schedule a flush (in practice various things force style recalcs and this doesn't occur
        commonly).

        To avoid this we should flush unconditionally when the flush timer fires. This performs any pending
        style recalc and layout too. If there is nothing to do the flush will be cheap.

        PLT doesn't appear to hit cases affected by this patch and there shouldn't be any impact.

        Reviewed by Antti Koivisto.

        WebPageProxy::didPerformClientRedirect() had a MESSAGE_CHECK_URL() for both the source

        to make sure that both URLs were actually loaded by this WebContent process.

        However, now that we're enabled process-swap on cross-site navigation, these checks are no
        longer fully valid. If the client-side redirect is cross-site, then the source and destination
        URLs get loaded by 2 different WebContent processes. Since didPerformClientRedirect() gets
        called after the redirect and gets set by the new WebContent process, only the destination URL
        is guaranteed to have been loaded by this process. The source URL may have been loaded in
        another process so this patch drops the message check for the source URL.

        When a WebProcess crashes, we destroy the ViewGestureController and reconstruct it later
        after we've relaunched a new WebProcess. The ViewGestureController controller takes care
        of adding itself as an IPC message receiver to the WebProcessProxy, and the destructor
        takes care of removing itself as an IPC message receiver.

        However, when process-swapping on navigation, we do not destroy the ViewGestureController
        because doing so would take down the swipe gesture snapshot on cross-site swipe navigation.
        This led to hitting this assertion later on because the ViewGestureController is still
        registered as an IPC message receiver with the old process after process swapping.

        To address the issue, we now make sure the ViewGestureController unregisters itself from
        the old process and registers itself with the new process on process-swap.

        The crash was happening when switching to a suspended page that is not yet done
        suspending (e.g. in case of very fast back/forward navigation). The WebPageProxy
        would reattach to the suspended process and get load notifications that it did
        not expect since it did not schedule any load yet. Those notifications are for
        the about:blank load we do for page suspension.

        To address the issue, make swapToWebProcess() asynchronous and take a completion
        handler. When we try to unsuspend a SuspendedPageProxy, we first make sure it
        is actually done suspending. If it is not done suspending, we wait until it is
        before telling in to unsuspend and proceeding with the new load.

        Web Inspector: Keep Web Inspector window alive across process swaps (PSON) (Local Inspector)

        <rdar://problem/45470897>

        Reviewed by Timothy Hatcher.

        When a web page asks to open a local Web Inspector, that inspector
        will now connect in the UIProcess (WebPageProxy / WebPageInspectorController)
        instead of the WebContentProcess (WebKit::WebInspector / InspectorController).

        Previously a WebInspectorProxy was re-created every time the WebPageProxy's
        WebPage / WebProcess was changed, effectively closing the Web Inspector
        frontend when the WebPage was swapped or crashed.

        This change keeps the WebInspectorProxy alive as long as the WebPageProxy
        is alive. During process swaps, or process crashes, the WebInspectorProxy
        is reset when the page is reset and updated when the page's WebProcess
        changes. Since WebInspectorProxy owns the Web Inspector view / window
        the Web Inspector window can be kept alive across (and attached state)
        across WebPage / WebProcess changes.

        Previously the WebContentProcess's WebKit::WebInspector was the Local
        FrontendChannel for the WebCore::InspectorController. This can't
        outlive the single WebContentProcess.

        This change makes the UIProcesses' WebInspectorProxy the Local FrontendChannel
        for the WebKit::WebPageInspectorController. Given the WebInspectorProxy
        now stays alive alongside the WebPageProxy this will live across process changes.
        This means that the WebInspectorUI process must send its backend messages to
        the WebInspectorProxy -> WebPageInspectorController now instead of the
        old path WebInspector -> WebCore::InspectorController.

        A direct IPC connection is still maintained between the WebContentProcess's
        WebKit::WebInspector and the InspectorProcess's WebInspectorUI. Previously
        this connection was established by WebKit::WebInspector vending an
        IPC::Attachment to the WebInspectorUI process. This patch inverts that
        relationship, because the WebInspectorUI process now lives across multiple
        WebContentProcess changes. The WebInspectorUI now vends the IPC::Attachment
        to the WebContentProcess each time the process changes. This way they can both
        still communicate through normal Messages::WebInspector/WebInspectorUI
        messages and everything behaves as previously expected.

        IndexedDB.IndexedDBTempFileSize API test times out with process prewarming enabled
        https://bugs.webkit.org/show_bug.cgi?id=191671
        <rdar://problem/46086062>

        Reviewed by Alex Christensen.

        Enabling process prewarming caused IndexedDB.IndexedDBTempFileSize API to time out and print
        the following line:
        "Attempted to create a NetworkLoad with a session (id=2) that does not exist."

        This actually identified a pre-existing bug with our handling of non-default data store.
        Whenever a page starts using a data store, we call WebProcessPool::pageBeginUsingWebsiteDataStore()
        which will call NetworkProcessProxy::addSession() if the network process was already started
        to let the network process know about this non-default session. There are several issues with the
        current model:
        1. If the network process was not created yet when pageBeginUsingWebsiteDataStore() is called,
           then the network process will not know about the non-default session when it actually gets
           started later on. This is unlikely to happen in practice, except in case of network process
           crash because we create the network process as soon as we initialize the first WebProcessProxy.
        2. Even if we successfuly managed to register the session with the network process proxy, we get
           in trouble if the network process crashes or is terminated later on as we do not re-register
           those sessions with the new network process.

        To address these 2 issues, WebProcessPool::ensureNetworkProcess() now takes care of registering
        all the non-default sessions (that are associated with this process pool) with the new network
        process. The WebProcessPool knows about these sessions because it adds them to m_sessionToPagesMap
        whenever WebProcessPool::pageBeginUsingWebsiteDataStore() is called, even if the network process
        proxy was not created yet.

        The reason the IndexedDB.IndexedDBTempFileSize API test was failing was because it did:
        1. A load in a WebView V1 with a non-default session
        2. Process prewarming kicked in after this load and would create a new WebProcessProxy.
        3. Terminate the network process
        4. Another load in a WebView V2 with the same non-defaut session, which would reuse the
          prewarmed process. Because the network process was terminated, constructing the new
          page would not register the session ID with the new network process when
          pageBeginUsingWebsiteDataStore() is called.
        -> The load would hang because the new network process would not know about the
           non-default session when started later on.

        The bug was previously hidden without process prewarming because step 4 would create a *new*
        WebProcessProxy and WebProcessPool::initializeNewWebProcess() would call ensureNetworkProcess()
        so that pageBeginUsingWebsiteDataStore() would successfuly register the session with the
        network process later on.

        I wrote a second API test (WebKit.DoLoadWithNonDefaultDataStoreAfterTerminatingNetworkProcess)
        to demonstrate the pre-existing bug without process prewarming enabled.

        Use a real nonce for CTAPHID_INIT request according to:
        https://fidoalliance.org/specs/fido-v2.0-ps-20170927/fido-client-to-authenticator-protocol-v2.0-ps-20170927.html#ctaphid_init-0x06.
        The challenge here is the new transaction needs to start in the next runloop otherwise a dead lock will form:
        wrong nonce -> new transaction -> new nonce -> write init request -> read init response from last run as it
        piped in the run loop -> wrong nonce of course -> ...
        To break the above dead lock, we have to start the new transaction in the next run. However, that isn't
        sufficient as the arrived init response will be piped in HidConnection::m_inputReports, which is designed
        on purpose to store any data packets within (initialized, terminated) time interval to prevent data loss in
        the case when HidConnection::registerDataReceivedCallback is called after the first data packet's arrival.
        In order to break the dead lock completely, HidConnection::invalidateCache will bnnne called prior to every
        send to delete any potential init response from last run. HidConnection::invalidateCache is not necessary
        for other protocols though. The above scenario is more or less a design flaw in CTAP HID.

        Of course, all above scenarios are covered in our mock tests.

        WebKit.DecidePolicyForNavigationActionForHyperlinkThatRedirects API fails when PSON is enabled
        https://bugs.webkit.org/show_bug.cgi?id=191640

        Reviewed by Alex Christensen.

        The issue was that when process-swapping on a redirect, the parameters provided by the new
        WebContent process for navigationActionData / originatingFrameInfoData / frameSecurityOrigin
        are not correct because it does not have sufficient information (it does not know a swap
        happened).

        To address the issue, we now store the navigationActionData / originatingFrameInfoData /
        frameSecurityOrigin on the Navigation object whenever decidePolicyForNavigationAction is
        called. If the decidePolicyForNavigationAction is for a redirect, use the ones we stored
        on the Navigation object instead of the ones provided by the WebContent process. In case
        of redirect, those do not change anyway.

        This fixes all WebKit.DecidePolicyForNavigationAction* tests with PSON enabled.

        WebProcessPool::prewarmProcess() now tries to use the following data stores in this
        order of preference:
        1. WebProcessPool::m_websiteDataStore (aka this process pool's primary data store)
        2. The data store of the last WebProcessProxy that was created
        3. The default data store if it exists

        If no suitable data store is found, we cancel the process prewarming and log a console

        Web Inspector: Keep Web Inspector window alive across process swaps (PSON) (Remote Inspector)

        To support process swapping a slim Web Inspector backend lives in the UIProcess.
        The Web Inspector frontend connects to it and is told about sub-targets, namely
        pages, that it can further connect to. When performing a process swap the backend
        tells the frontend to destroy existing targets and create new targets.

        In the UIProcess the WebPageProxy has a WebPageInspectorController, with a single
        TargetAgent holding InspectorTargetProxies to targets it knows about. Inspector
        protocol messages go through this inspector controller and are routed to the
        WebPage and its WebCore::Page's InspectorController. The WebPageProxy decides
        when to close and expose new page targets during process swap, or basically
        any time it reconnects to a WebProcess. So this patch also makes Web Inspector
        stay alive and reconnect to a page when the inspected page crashes!

        In the WebContentProcess the WebPage has a WebPageInspectorTarget. It also
        has a WebPageInspectorTargetController in anticipation of further sub-targets
        within the page (workers, frames) but none exist at the moment. The WebPage
        relies on the WebPageProxy to know when to expose this target as a debuggable.

        Add SPI to show a safe browsing warning
        https://bugs.webkit.org/show_bug.cgi?id=191604

        Reviewed by Andy Estes.

        Safari has a case where it shows safe browsing warnings for a reason other than being told to by the SafeBrowsing framework.
        Because safe browsing is moving to WebKit, we will have Safari call this WebKit SPI in that case.
        The warning looks a little different, so I had to change the structure of a SafeBrowsingResult and the location of the string processing,
        but the existing behavior is the same as verified by existing unit tests.  I added a unit test to verify behavior of the new SPI.

        [iOS] A few drag and drop tests are crashing after r238146
        https://bugs.webkit.org/show_bug.cgi?id=191617

        Reviewed by Dean Jackson.

        The notion of temporarily suppressing the selection assistant was introduced during iOS drag and drop
        development as a way of allowing both the selection view and dropped content snapshot to fade in simultaneously
        during a drop in an editable element. r238146 piggy-backs on this mechanism by changing selection suppression
        state when an element is focused, when the selection changes, and when an element is blurred, depending on
        whether the currently focused element is transparent.

        However, in the case where the selection assistant is suppressed due to a running drop animation, if focus moves
        to an element that is not fully transparent, we end up prematurely unsuppressing the text selection assistant.
        This subsequently causes selection UI to immediately show up after a drop instead of animating in alongside a
        snapshot of the inserted document fragment, if the drop moved focus to an editable element.

        A number of drag and drop tests on iOS exercised this codepath by dragging content into editable fields and/or
        moving content between editable elements in a web view. These tests began to crash due to selection views and
        the accompanying callout bar appearing earlier than usual, which triggers an unrelated UIKit assertion in
        <https://webkit.org/b/190401>.

        This patch fixes the failing tests by refactoring our selection assistant suppression code. Instead of
        maintaining a single `BOOL` flag indicating whether the selection is suppressed, we use an `OptionSet` of
        `SuppressSelectionAssistantReason`s, which (at the moment) only include (1) a running drop animation, and (2)
        focusing a transparent element. The text selection assistant is considered suppressed when either of the reasons
        apply. This allows us to correctly handle a drop animation that occurs simultaneously as an element is focused
        without unsuppressing the selection assistant early, and also allows us to handle selection assistant
        suppression in more nuanced ways, depending on the suppression reason.

        Since `-makeTextWritingDirectionNatural:` is already declared on both iOS and macOS (SPI on UIResponder and API

        Client should be able to disable PSON even if the experimental feature is on by default

        Instead of overriding the APIProcessPoolConfiguration's m_processSwapsOnNavigation flag to true
        when the experimental is enabled, use a separate flag to store this information. If the client
        explicitly sets the APIProcessPoolConfiguration's m_processSwapsOnNavigation flag then we obey
        the client's request, otherwise, we fall back to using the state from experimental features.

        This allows:
        - API tests to explicitely disable PSON / Process prewarming even if those are on by default
          in experimental features.
        - If the client does not set those flags on the APIProcessPoolConfiguration (Safari for e.g.),

        Align Mac WK2 layer flush throttling with iOS
        https://bugs.webkit.org/show_bug.cgi?id=191632

        Reviewed by Zalan Bujtas.

        Currently Mac WK2 uses WebCore side throttling implementation in RenderLayerCompositor. This code has
        throttling timer per-frame while the actual decision making and layer flushes itself are per page. These
        timers generate way more flushes than expected in presence of multiple frames. There are also bugs in how
        flushing state is updated when frames are created dynamically.

        On iOS WK2 throttling is implemented on WebKit side and controlled by a per-page timer. Recent fixes also
        make this implementation visually fast. We should align the Mac implementation and eventually unify them.

        This patch implements throttling in TiledCoreAnimationDrawingArea mirroring the iOS RemoteLayerTreeDrawingArea
        implementation. There are some adjustments for platform differences (local vs remote layers) and we continue
        using runloop observer for the actual flushes. Timings are as in the existing Mac code.

        The patch appears to be a significant performance progression.

        Stop setting the WebProcessPool's primary data store (m_websiteDataStore) to the default one in
        WebProcessPool::prewarmProcess(). We did not really need to, we can pass the default data store
        to the new WebPageProxy without having to set m_websiteDataStore. m_websiteDataStore only gets
        set upon constructor if thr default data store already exists or later on when creating a WebPage
        that uses the default data store.

        In the case of the API test, the following was happening:
        1. Create an ephemeral data store EDS
        2. Create a WebView V1 using datastore EDS
        3. Do a load in V1
        4. Process prewarming would kick in and wrongly associated V1's process pool PP1 with the default data store
        5. Create/Get the default datastore and set a few cookies on it
        6. Create a WebView V2 using default datastore and a fresh new process pool PP2
        7. Do a load in V2 and expect the cookies to be there

        In HTTPCookieStore::setCookie() that is called at step 5, we call:
        m_owningDataStore->processPoolForCookieStorageOperations()

        In this case, m_owningDataStore is the default datastore and this call would previously return null because
        there is no WebProcessPool yet associated with the default datastore. However, with the process prewarming
        bug at step 4, the process pool PP1 would be returned since it was wrongly associated with the default
        data store. As a result, we would call setCookie() on PP1's WebCookieManagerProxy and this would fail
        because PP1's network process knows nothing about this session ID (it was only ever used with an ephemeral
        session).

        [WebAuthN] Support CTAP HID authenticators on macOS
        https://bugs.webkit.org/show_bug.cgi?id=188623
        <rdar://problem/43353777>

        Reviewed by Brent Fulgham and Chris Dumez.

        This patch introduces a primitive support of CTAP HID authenticators for WebAuthN in macOS.
        It involves low level HID device management&communication, high level CTAP HID authenticator
        management&communication, and mock testing. The above three aspects will be covered in details:
        1) Low level HID device management&communication: HidService&HidConnection
        It relies on IOHIDManager to discover appropriate hid devices by passing a matching dictionary:
        { PrimaryUsagePage: 0xf1d0, PrimaryUsage: 0x01}. For communication, it utilizes HID reports.
        To send a report, it calls IOHIDDeviceSetReport since the async version is not implemented.
        To recieve a report, it calls IOHIDDeviceRegisterInputReportCallback to asynchronously wait
        for incoming reports.
        Here is the corresponding reference:
        https://developer.apple.com/library/archive/documentation/DeviceDrivers/Conceptual/HID/new_api_10_5/tn2187.html#//apple_ref/doc/uid/TP40000970-CH214-SW2
        2) High level CTAP HID authenticator management&communication: HidService&CtapHidDriver
        Whenever an appropriate hid device is discovered by IOHIDManager, an AuthenticatorGetInfo command
        is sent to the device to determine properties of the authenticator, says, which version of protocol
        it supports, i.e. CTAP or U2F. So far, we only support CTAP authenticators. Once the authenticator
        is determined to support CTAP, we then instantiate CtapHidAuthenticator which will then take care
        of even higher level WebAuthN requests&responses.
        Binaries are constructed and packaged according to the CTAP HID porotocol. CtapHidDriver takes care
        of concurrency and channels, i.e. allocating channel and establishing the actual request/response
        transaction. At the meantime, CtapHidDriver::Worker is then responsible for each single transaction.
        Here is the corresponding reference:
        https://fidoalliance.org/specs/fido-v2.0-ps-20170927/fido-client-to-authenticator-protocol-v2.0-ps-20170927.html#usb.
        3) Mock Testing: MockHidService & MockHidConnection
        A CTAP hid authenticator is simulated within MockHidConnection with options of specifying specific
        error scenarios and of course could take care of successful cases. Four stages are presented in the
        simulated authenticator to reflect: a) allocating channel for AuthenticatorGetInfo, b) sending
        AuthenticatorGetInfo, c) allocating channel for actual request, and d) sending the actual request.

        Besides implementing the above, it also does a few other things:
        1) Make AuthenticatorManager::clearState asynchronous to avoid cyclic dependency:
        Authenticator::returnResponse => AuthenticatorManager::respondReceived => AuthenticatorManager::clearState
        => Authenticator::~Authenticator.
        2) Reorganize unified build sources to make it clear that which files are .mm and which are .cpp.
        3) Import LocalAuthentication.framework in LocalAuthenticationSoftLink instead of being scattered.

        [iOS] Do not show selection UI for editable elements with opacity near zero
        https://bugs.webkit.org/show_bug.cgi?id=191442
        <rdar://problem/45958625>

        Reviewed by Simon Fraser.

        Add support for suppressing native selection UI (for instance, selection highlight views, selection handles, and
        selection-related gestures) when the selection is inside a transparent editable element. This helps maintain
        compatibility with text editors that work by capturing key events and input events hidden contenteditable
        elements, and reflect these changes in different document or different part of the document.

        Since selection UI is rendered in the UI process on iOS using element geometry propagated from the web process,
        selection rendering is entirely decoupled from the process of painting in the web process. This means that if
        the editable root has an opacity of 0, we would correctly hide the caret and selection on macOS, but draw over
        the transparent element on iOS. When these hidden editable elements are focused, this often results in unwanted
        behaviors, such as double caret painting, native and custom selection UI from the page being drawn on top of one
        another, and the ability to change selection via tap and loupe gestures within hidden text.

        To fix this, we compute whether the focused element is transparent when an element is focused, or when the
        selection changes, and send this information over to the UI process via `AssistedNodeInformation` and
        `EditorState`. In the UI process, we then respect this information by suppressing the selection assistant if the
        focused element is transparent; this disables showing and laying out selection views, as well as gestures
        associated with selection overlays. However, this still allows for contextual autocorrection and spell checking.

        (-[WKContentView _startAssistingNode:userIsInteracting:blurPreviousNode:changingActivityState:userObject:]):

        When an element is focused, begin suppressing the selection assistant if the element is fully transparent.

        (-[WKContentView _stopAssistingNode]):

        When the focused element is blurred, reset state by ending selection assistant suppression (additionally
        reactivating the selection assistant if needed). This ensures that selection in non-editable text isn't broken
        after focusing a hidden editable element.

        (-[WKContentView _updateChangedSelection:]):

        If needed, suppress or un-suppress the selection assistant when the selection changes. On certain rich text
        editors, a combination of custom selection UI and native selection UI is used. For instance, on Microsoft Office
        365, caret selections are rendered using the native caret view, but as soon as the selection becomes ranged, the
        editable root becomes fully transparent, and Office's selection UI takes over.

        (-[WKContentView _shouldSuppressSelectionCommands]):

        Override this UIKit SPI hook to suppress selection commands (e.g. the callout bar) when suppressing the
        selection assistant.

        SuspendedPageProxy object alive if there is no longer any WebBackForwardListItem pointing
        to it.

        To address the issue, WebBackForwardListItem nows tells the WebProcessPool to destroy
        its SuspendedPageProxy when necessary. WebBackForwardList also takes care of nulling

        Prefixes a few iOS-only SPI methods declared on WKWebView in r236867 with underscores, and also exposes some
        more cross-platform Cocoa editing SPI. Once the unprefixed SPI methods are no longer used by internal clients,
        these will need to be removed (see followup bug: webkit.org/b/191450). See below for more details.

        Covered by new and existing API tests in WKWebViewEditActions.

        * UIProcess/API/Cocoa/WKWebView.mm:

        Hoist the definition (and undefinition) of `FORWARD_ACTION_TO_WKCONTENTVIEW` to encompass both the WKWebView

        Create .xcfilelist files
        https://bugs.webkit.org/show_bug.cgi?id=191324
        <rdar://problem/45852819>

        Reviewed by Alex Christensen.

        As part of preparing for enabling XCBuild, create and use .xcfilelist
        files. These files are using during Run Script build phases in an
        Xcode project. If a Run Script build phase produces new files that are
        used later as inputs to subsequent build phases, XCBuild needs to know
        about these files. These files can be either specified in an "output
        files" section of the Run Script phase editor, or in .xcfilelist files
        that are associated with the Run Script build phase.

        This patch takes the second approach. It consists of three sets of changes:

        - Modify the DerivedSources.make files to have a
          'print_all_generated_files" target that produces a list of the files
          they create.

        - Create a shell script that produces .xcfilelist files from the
          output of the previous step, as well as for the files created in the
          Generate Unified Sources build steps.

        - Add the new .xcfilelist files to the associated projects.

        Note that, with these changes, the Xcode workspace and projects can no
        longer be fully loaded into Xcode 9. Xcode will attempt to load the
        projects that have .xcfilelist files associated with them, but will
        fail and display a placeholder for those projects instead. It's
        expected that all developers are using Xcode 10 by now and that not
        being able to load into Xcode 9 is not a practical issue. Keep in mind
        that this is strictly an IDE issue, and that the projects can still be
        built with `xcodebuild`.

        Also note that the shell script that creates the .xcfilelist files can
        also be used to verify that the set of files that's currently checked
        in is up-to-date. This checking can be used as part of a check-in hook
        or part of check-webkit-style to sooner catch cases where the
        .xcfilelist files need to be regenerated.

        * DerivedSources.make:
        * DerivedSources.xcfilelist: Added.
        * UnifiedSources.xcfilelist: Added.

        Don't use the main queue to create an XPC connection. xpc_connection_set_bootstrap does
        dispatch_mach_send_barrier_f on this queue which delays the sending of the subsequent
        bootstrap message (sent to launchd for launching a new target process) when the main queue is busy.

        Now that the XPC connection runs on the default concurrent queue, errorHandler could be invoked
        by any thread. The job of errorHandler is to dispatch errorHandlerImpl to the main thread,

        Resource Load Statistics: Remove cap on partitioned cache max age if it matches a network reload (redirect-only)

        When a redirect cache entry for a prevalent resource reaches its max
        age cap, it is loaded again from the network and the network response
        is compared with what's in the cache. If it's a match, the cache entry
        is fully accepted. If not, a new capped cache entry is created.

        [PSON] Reuse SuspendedPages' process when possible, for performance
        https://bugs.webkit.org/show_bug.cgi?id=191166

        Reviewed by Geoffrey Garen.

        When process-swapping check if there is an existing SuspendedPage for the domain we're going to.
        If there is, use this SuspendedPage's process for the navigation instead of a fresh new process.
        This change should be beneficial for performance as it:
        - Avoids spinning up a new process (CPU & memory cost)
        - Likely better leverages caches since this process already loaded this domain in the past

        Due to current limitations, using a SuspendedPage's proxy may consume the SuspendedPage, which
        means that it can no longer be used for PageCache on history navigations. We need to do this when
        the SuspendedPageProxy in question was created for the current WebPageProxy because:
        - This SuspendedPageProxy's process already has a suspended WebPage with this WebPageProxy's pageID
        and
        - We do not currently support having more than one WebPage with a given pageID within a single
          WebProcess.

        For performance reasons, the ResourceRequest IPC encoder does not encode the request's HTTP body (aka form data).
        When we decide to process-swap for a POST request in WebPageProxy::decidePolicyForNavigationAction(), the request
        we pass the new WebProcess thus no longer has a HTTP body and the load will likely fail in the new process.

        To address the issue, we now pass the request body along with the request when sending the DecidePolicyForNavigationActionAsync
        / DecidePolicyForNavigationActionSync IPC from the WebProcess to the UIProcess. No action is needed for the
        LoadRequest IPC to the new WebProcess since the LoadParameters' IPC encoder takes care of encoding the request's
        body already.

        [PSON] Only delay attaching drawingArea in case of process swap and drop DidCompletePageTransition IPC handshake
        https://bugs.webkit.org/show_bug.cgi?id=190971

        Reviewed by Geoffrey Garen.

        Only delay attaching drawingArea in case of process swap and drop DidCompletePageTransition IPC handshake.

        Since r236257, the WebProcess would always delay attaching the drawing area when a new WebPage is created. The
        WebProcess would send a DidCompletePageTransition IPC to the UIProcess when the page transition is complete and
        the UIProcess would then send an IPC back to attach the drawing area.

        In the new design, WebPageCreationParameters contains a flag indicating if the WebPage should delay attaching
        the drawing area or not. We only delay attaching in case of process swap and we've successfuly suspended the
        previous page. Then when WebPage::didCompletePageTransition(), we stop sending the DidCompletePageTransition
        IPC to the UIProcess and instead have the WebProcess attach the drawing area right away if we've delayed
        attaching until then.

        Avoid tearing down the drawing area when suspending a WebPage due to process-swap. We really only need to reset

        https://bugs.webkit.org/show_bug.cgi?id=189743

        Reviewed by Michael Catanzaro.

        Disassociate resizing that can be done on an AcceleratedSurface object
        between "host resizes" and "client resizes".

        The former is done from ThreadedCoordinatedLayerTreeHost directly, and
        is currently used only for GTK on X11, where a new pixmap object is
        created on each resize, which affects the context ID that is based on
        that pixmap object's address.

        The latter is done from the composition thread. It's used for GTK on
        Wayland and WPE. In both cases, the underlying window object does not
        change on each resize, but it's necessary to perform the actual resize
        on the composition thread.

        So far it hasn't been performed there, which ended up pushing sizes of
        the WebKit view and the underlying window object out of sync during
        resizing, leaving parts of window unrendered.

        When the network process serializes certificate data to other

        present, is lost. In practice this means that applications using

        [iOS] [Datalist] Can't pick datalist suggestions in a stock WKWebView
        https://bugs.webkit.org/show_bug.cgi?id=190621
        <rdar://problem/45310649>

        Reviewed by Tim Horton.

        Fixes the bug by refactoring datalist suggestion information on iOS; currently, we override text suggestions on
        _WKFormInputSession. This only works for a few internal clients (including Safari) that set a _WKInputDelegate
        and also implement either -_webView:willStartInputSession: or -_webView:didStartInputSession:, which is
        necessary in order to ensure that WebKit creates and maintains a form input session.

        The two pieces of information that datalist code needs to vend to WKContentView are a list of UITextSuggestions
        and a custom input view, which are both currently properties of _WKFormInputSession. This patch lifts these out
        of the input session and makes them properties of WKContentView, which are used in
        WebDataListSuggestionsDropdownIOS.

        Pull out common logic when resigning first responder or tabbing to the next or previous text field into a new

        when editing has ended; the input peripheral and suggestions input view use this chance to send the value of the
        form control to the web process.

        (-[WKContentView resignFirstResponderForWebView]):
        (-[WKContentView inputView]):

        If a custom input view is not set but we have an input view for a datalist's text suggestions, use the datalist

        suggestions, then we simply use suggestions from the current datalist (if present).

        <rdar://problem/45349024>

        Reviewed by Alex Christensen.

        This patch adds the following:
        - The WebProcessPool now tells the WebsiteDataStore when a network process has
            been created.
        - The WebsiteDataStore in turn tells the WebResourceLoadStatisticsStore when
            a network process has been created.
        - The WebResourceLoadStatisticsStore makes sure to update the network processes
            with its cookie policy when it's notified that a network process has been
            created.

        In addition, this patch changes the following:
        - The ResourceLoadStatisticsMemoryStore no longer keeps track of which domains
            it has told the network process to block cookies for. The reason is that
            we cannot assume that there is only one network process so we should
            always send complete blocking data.
        - The ResourceLoadStatisticsMemoryStore's functions for communicating cookie
            blocking state to the network process no longer take and forward the
            "clear first" parameter. This is because complete data is sent every time
            and thus the network process' set is always cleared on an update.
        - Removes WebsiteDataStore::networkProcessDidCrash() and
            WebResourceLoadStatisticsStore::scheduleCookieBlockingStateReset() since
            the call site---WebProcessPool::ensureNetworkProcess()---now calls
            WebsiteDataStore::didCreateNetworkProcess() after a network process
            crash and the state sync for cookie blocking is triggered.

        Introduce CompletionHandler-based Async IPC messages with replies
        https://bugs.webkit.org/show_bug.cgi?id=190746

        Reviewed by Tim Horton.

        Before this patch, to make an asynchronous IPC message with a reply you had to find two objects that
        can talk to each other, make two new message types, send a generated identifier, keep track of that
        identifier, make a HashMap somewhere to store the object waiting for the response, and hook it all up.
        What a mess.  No wonder people take shortcuts and make strange design decisions.

        Now, you can just use a CompletionHandler and mark the reply as Async in *.messages.in.
        I've adopted this with a message whose behavior is covered by the storage/indexeddb/modern/blob-cursor.html
        layout test and many others.  I intent to refine and further adopt this incrementally.

        WebPageProxy::didCompletePageTransition() may interact with a SuspendedPageProxy from a previous navigation. We need
        to reset m_lastSuspendedPage whenever the page starts a new navigation as m_lastSuspendedPage is only updated when
        we process-swap otherwise.

        Also rename the data member to m_pageSuspendedDueToCurrentNavigation for clarity.

        In a follow-up, I will see if I can get rid of this data member entirely or maybe move it to the Navigation
        object.

        Handle MDNS resolution of candidates through libwebrtc directly
        https://bugs.webkit.org/show_bug.cgi?id=190681

        Reviewed by Eric Carlson.

        Add support for AsyncResolver to resolve MDNS.
        This basically reuse the code path used to resolve STUN server addresses.
        Removed MDNS specific resolution.
        Use existing CFHost resolution mechanism to do the actual resolution.

        Cap number of SuspendedPageProxy objects to 3 to avoid accumulating too many "suspended" processes.

        Also allow a WebPageProxy to have more than one SuspendedPageProxy so that PageCache now works for
        more than 1 history navigation (up to 3 with the suspended page limit in this patch).

        The following cleanup / refactoring was made to support this:
        - The SuspendedPageProxy objects are now owned by the WebProcessPool instead of the WebPageProxy.
          The WebProcessPool is in charge of limiting the number of SuspendedPageProxy objects by dropping
          the oldest one whenever a WebPageProxy tries to add a new one and we've already reached the limit.
        - WebProcessProxy no longer needs to know anything about suspended pages, which simplifies the
          code quite a bit. Instead, the SuspendedPageProxy objects now register themselves as
          IPC::MessageReceivers with their WebProcessProxy. The SuspendedPageProxy also take care of
          calling maybeShutdown() on their WebProcessProxy when they get destroyed.

        The test is doing the following:
        > document.execCommand("Delete"); document.execCommand("Undo");

        Both operation are synchronous and rely on synchronous IPC from the WebProcess to the UIProcess.
        However, for the undo operation to succeed, the first command need to have been registered with
        with the UIProcess via the WebPageProxy::RegisterEditCommandForUndo IPC to the UIProcess, which
        is asynchronous.

        After r236512, the UIProcess no longer processes incoming sync / async IPC in order and thus,
        it is possible for the WebPageProxy::ExecuteUndoRedo synchronous IPC to get processed by the
        UIProcess *before* the WebPageProxy::RegisterEditCommandForUndo asynchronous IPC for the
        previous "Delete" command. As a result, canUndo would return false and we would fail to undo.

        To address the issue, use SendOption::DispatchMessageEvenWhenWaitingForSyncReply flag when sending
        the WebPageProxy::RegisterEditCommandForUndo IPC, so that it gets processed in order with regards
        to surrounding synchronous IPC.

        In r230686, we switched from using UIWKSelectionAssistant to UIWKTextInteractionAssistant for handling selection

        trigger text selection when long pressing.

        After dismissing the keyboard by tapping the "Done" button, the UITextInteractions and gesture recognizers on
        the interaction assistant include:

            <UITextInteraction>
                …
                <UITextIndirectNonEditableInteraction>
                    <_UIKeyboardBasedNonEditableTextSelectionInteraction>
                      ↳ "_UIKeyboardTextSelectionGestureForcePress" → <_UITextSelectionForceGesture>

        However, after the keyboard dismisses due to an editable element losing focus, the UITextInteractions on the
        interaction assistant look like this:

            <UITextInteraction>
                …
                <UITextIndirectNonEditableInteraction>

        Subsequently, the lack of a `_UIKeyboardBasedNonEditableTextSelectionInteraction` makes text selection by long
        pressing impossible, since the `_UITextSelectionForceGesture` is never introduced to `WKContentView`. In UIKit,
        `UITextIndirectNonEditableInteraction` only adds `_UIKeyboardBasedNonEditableTextSelectionInteraction` as a
        child if the text input view — in our case, WKContentView — is missing an input delegate (see `-initWithView:`).
        In the case where the Done button is used to dismiss the keyboard, WKContentView loses first responder, and the
        input delegate of WKContentView is cleared out early on, before we call `-stopAssistingKeyboard`:

            -[WKContentView(WKInteraction) setInputDelegate:]
            -[UIKeyboardImpl setDelegate:force:]
            -[UIPeripheralHost(UIKitInternal) _reloadInputViewsForResponder:]
            -[UIResponder _finishResignFirstResponder]
            -[UIResponder resignFirstResponder]
            -[WKContentView(WKInteraction) resignFirstResponderForWebView]
            -[UIKeyboardImpl dismissKeyboard]

        However, in the case where the focused element is blurred, we end up clearing out the delegate in
        `-_stopAssistingNode`, *after* we've already called `-setGestureRecognizers` on the interaction assistant. This
        means UIKit will skip adding `_UIKeyboardBasedNonEditableTextSelectionInteraction` to the text interaction
        assistant.

            -[WKContentView(WKInteraction) setInputDelegate:]
            -[UIKeyboardImpl setDelegate:force:]
            -[UIPeripheralHost(UIKitInternal) _reloadInputViewsForResponder:]
            -[UIResponder(UIResponderInputViewAdditions) reloadInputViews]
            -[WKContentView(WKInteraction) _stopAssistingNode]

        To fix this, we simply reset our `inputDelegate` earlier in `_stopAssistingKeyboard` instead of waiting until
        we reload input views. This ensures that UIKit sets up the text interaction assistant's gestures when changing
        focus in the same way as we would when the keyboard is dismissed via `-resignFirstResponder` (e.g. when pressing
        the Done button).

        When the inspector is placed next to the web view it uses its _topContentInset and _totalHeightOfBanners
        to lay out the inspector so it does not underlap the window toolbar, but this technique does not work when
        in responsive design mode because of the different attachment view. This patch fixes the issue by using
        -[NSWindow contentLayoutRect] to figure out the height of the inspector instead of relying on the content
        insets of the web view. This requires observing -contentLayoutRect and ensure we only observe its changes

        Reviewed by Tim Horton.

        r237087 added support for changing the view scale on iOS, by making it possible to let the minimum layout size
        be a factor of the view size; this allows internal clients to change page zoom levels on iOS. Currently,
        changing the page zoom level automatically zooms to the new initial scale only if the user has not manually
        scaled the page before, even if the page is already at initial scale (e.g. after the user double taps to zoom on
        a small element, and double taps again to zoom back out to initial scale).

        This patch makes some minor adjustments to automatically zoom to the new initial scale after changing the view
        scale, as long as the page was at initial scale when changing zoom levels.

        [GTK][WPE] Implement subprocess sandboxing
        https://bugs.webkit.org/show_bug.cgi?id=188568

        Reviewed by Michael Catanzaro.

        This implements sandboxing of WebKitWebProcesses.

        The sandbox is opt-in at runtime as it is a behavior change.
        See webkit_web_context_set_sandbox_enabled() and the
        WEBKIT_FORCE_SANDBOX env var for developers.

        This is Linux specific using Namespaces, Seccomp, and a DBus proxy service.
        This introduces three new dependencies:

        - bwrap executable
        - libseccomp library
        - xdg-dbus-proxy executable

        The use of xdg-dbus-proxy will ideally be replaced once upstream DBus
        gains the same filtering abilities which is a work in progress.

        Currently the sandbox is not completed and there are a few large holes:

        - Pulseaudio: The Pipewire project will solve this.
        - DRI device access: No immediate solutions planned.
        - Webcam device access: Pipewire will also solve this.
        - Webprocess network access: Will require GStreamer changes.
        - DConf access: Custom proxy planned.
        - X11 access: Wayland solves this.

        That is not an exhaustive list but are the noteworthy ones. Filesystem access
        is still an evolving list as problems are found as is specific DBus name access.

        causes the page to lay out at a larger width and shrink (or a smaller width and expand) to fit the viewport.

        [GTK][WPE] Add mediaDevices.enumerateDevices support
        https://bugs.webkit.org/show_bug.cgi?id=185761

        Reviewed by Youenn Fablet.

        Implemented the enumerateDevices API using a new WebKit class
        (DeviceIdHashSaltStorage) that generates and stores the device ids
        hash salts per origin, used to avoid fingerprinting in the
        webpages.

        The patch also adds a new type of data for the WebsiteDataStore.
        That way the users can call the WebsiteDataStore to show what
        origins have hash salt generated and remove them at some point.

        For the moment just GTK+ and WPE ports are using this class to
        generate the hash salts. The patch adds code to the
        checkUserMediaPermissionForOrigin API implementation, it was empty
        until now for these ports. In this function we create an instance
        of a new class WebKitDeviceInfoPermissionRequest that implements
        the WebKitPermissionRequestIface interface, that allows the ports
        to use the current permission managers implemented in the
        embedders to handle this new kind of request the way they like
        it. The default implementation is deny.

        The class WebKitDeviceInfoPermissionRequest takes care of
        contacting the DeviceIdHashSaltStorage and request/regenerate the
        hash salts accordingly.

        Persistency is still not implemented, we will add it in a
        future patch.

        Reviewed by Simon Fraser.

        There's a race in WKKeyboardScrollingAnimator that's exacerbated by HIDEventGenerator
        being much faster than a human finger. We get our "begin" events from interpretKeyEvent,
        after the Web Content process has had its way with it, but currently the
        back-channel "handle" events (e.g. for key up, which doesn't go to interpretKeyEvent)
        are retrieved from handleKeyWebEvent in the UI process, which is *before*
        the Web Content process has had a swing at it.

        If you lose the race (an insanely short tap like you get from HIDEventGenerator,
        or with a very busy Web Content process), we see handle(keyDown), handle(keyUp), begin(keyDown),
        and get stuck scrolling!

        Instead, retrieve the out-of-band "handle" events from _didHandleKeyEvent,
        so that they're sensibly and strictly ordered with respect to the timing of interpretKeyEvent/"begin".

        Also, hook up didFinishScrolling, so that UIScriptController's callbacks work correctly.

        Reviewed by Geoffrey Garen.

        When process swapping and "suspending" the previous WebProcess in a SuspendedPageProxy,
        we need to keep around the main frame's ID that still exists on in this process. This
        is needed so that we can re-create a UI-side WebFrameProxy for the WebFrame that exists
        in the WebProcess, if we ever swap back to this suspended process (see login in
        WebPageProxy::swapToWebProcess()).

        The bug was that the main frame ID was stored on the WebPageProxy via m_mainFrameID instead of the
        SuspendedPageProxy. This means that m_mainFrameID would get overriden when navigating in the new
        WebProcess with the value 1 (because WebFrame identifiers start at 1 and are per-WebProcess).
        This would lead to us constructing a WebFrameProxy with the wrong frame identifier in
        WebPageProxy::swapToWebProcess(), which would override an existing unrelated WebFrame in the
        WebProcessProxy's HashMap of frames. This would lead to crashes later on as the WebFrame
        would not be associated to the WebPageProxy we expect.

        Process swapping was sometimes not happening via URL bar navigation on iOS due to top-hit preloading,

        [Mac] Web Automation: some keyboard interactions don't generate events, causing event simulation to stall

        Reviewed by Tim Horton.

        Some users have reported that Cmd-A for Select All no longer works in safaridriver.
        Instead, this hangs the session. This happens because the WebAutomationSession class
        assumes that each call to simulateKeyboardInteraction causes keyboard events to be processed,
        but in corner cases like Cmd-A, some events that we simulate are swallowed by AppKit and
        never make it back to WebKit. Because the session never gets the "keyboard events flushed"
        callback, it assumes the interaction is still ongoing, and never returns, causing a hang.

        This patch consists of two parts:
         - Add logging of important state changes and events when simulating user input.
         - Make code more robust when simulating key actions that generate no events on macOS.

        Adjust keyboard scrolling animator to springy and semiphysical
        https://bugs.webkit.org/show_bug.cgi?id=190345
        <rdar://problem/43494393>

        Reviewed by Simon Fraser.

        Introduce WKKeyboardScrollViewAnimator, which wraps WKKeyboardScrollingAnimator
        and provides a reasonable set of default behaviors for UIScrollView.
        This is the first step on the way to WKKeyboardScrollingAnimator
        being platform- and toolkit-agnostic, and helps avoid adding a whole
        bunch of code to WKContentView.

        Adopt UIKit's scroll-to-top animation curve for whole-document scrolls.

        Adjust WKKeyboardScrollingAnimator's physics; it now simulates a spring
        attached to the page when decelerating. When a key is pressed, it applies
        a constant force to the page (up to some maximum velocity). When released,
        the spring causes the page to decelerate smoothly.

        Add rubber-banding to keyboard scrolling, based on the same spring that
        decelerates the page.

        Remove the initial bounce on keydown before starting the smooth scroll.

        Remove arrow key commands from WKContentView; this avoids double-processing
        incoming arrow key events, makes the event stream make more sense, and was
        entirely unnecessary.

        * Platform/spi/ios/UIKitSPI.h:
        Add a wide variety of useful SPI.

        also conforms to <UIResponderStandardEditActions>. This patch implements nearly all of the remaining
        unimplemented methods on UIResponderStandardEditActions, and the new extension augments this set of editing
        methods by adding additional editing helpers that don't currently exist on iOS (e.g. toggleStrikeThrough and
        insertUnorderedList). The names of these new methods have been largely been borrowed from their counterparts on
        macOS (see: `NSResponder.h`).

        The new edit actions are added in this patch on iOS are:

        ```
        - (void)alignCenter:(id)sender;
        - (void)alignJustified:(id)sender;
        - (void)alignLeft:(id)sender;

        Web Automation: clear pending callbacks when the session terminates

        Reviewed by Joseph Pecoraro.

        WebAutomationSession::terminate() can be called at any time to nuke the session.
        However, it's possible that the session is in the midst of simulating keyboard/mouse
        events. While in that state, there are some CompletionHandler objects waiting
        for key/mouse events to be flushed. We need to empty out callback maps with
        CompletionHandler instances so that they do not assert because they were never called.

        I was able to test this manually by running a test that erroneously hangs
        while waiting for keyboard input. While the test was hung, I killed the NetworkProcess
        manually to trigger WebAutomationSession::terminate(). From there, I saw that the
        Perform Actions REST API call gets cancelled with the appropriate error code.

        When searching a PDF document on MobileSafari, the maximum number of matching
        terms are limited to a set constant. Beyond this limit, a PDF document should not
        be searched, since the UI will not be updated correspondingly. To this effect,
        a new SPI was made to cancel a search when the maximum limit of matching terms
        is reached. This is done without clearing the highlighting for the all the terms
        that were found under the limit. This bug was a result of not having implemented 
        the new SPI in WKPDFView.

        [macOS] Implement a way for the UI process to request typing attributes at the current selection
        https://bugs.webkit.org/show_bug.cgi?id=189983
        <rdar://problem/44648705>

        Reviewed by Ryosuke Niwa.

        Implements `-[WKWebView typingAttributesWithCompletionHandler:]`, which asynchronously retrieves an NSDictionary
        containing the typing attributes at the start of the current selection. This is a new asynchronous text input
        client hook on macOS that is needed in order to support NSInspectorBar on WKWebView.

        At a high level, this patch builds on top of refactoring done in r236445 to make it possible to send typing
        attributes from the web process to the UI process, and then adds plumbing in the WebKit2 client layer to surface
        typing attributes to WKWebView on macOS.

        Retain a clone of a received UIEvent if it is for a hardware key event so as to ensure that we
        notify the UIKit keyboard code of the correct keyboard event.

        Currently the UIProcess retains the UIEvent associated with a keyboard event so as to defer
        notifying the UIKit keyboard code (via -_handleKeyUIEvent) about a received keyboard event until
        after the WebProcess has processed the raw key event. If this UIEvent is for a hardware keyboard
        event then it is not sufficient to retain it to preserve its value because UIKit uses a singleton
        UIEvent for all hardware keyboard events ;=> its value will be clobbered as each hardware keyboard
        event is received. Instead we need to explicitly clone a UIEvent for a hardware key event before
        retaining it.

        NetworkCache::Storage by default limits the length to read to 1500 milliseconds.
        This is good for the HTTP cache since networking might be faster.
        It does not work for DOM cache which needs to get these resources even if it takes a long time.

        Since this is disabled by a Mode::Testing option, use it for DOMCache after renaming it to Mode::AvoidRandomness.

        The WebContent process should not process incoming IPC while waiting for a sync IPC reply
        https://bugs.webkit.org/show_bug.cgi?id=184183
        <rdar://problem/36800576>

        Reviewed by Ryosuke Niwa.

        In recent years, we have experienced re-entrancy bugs/crashes in WebCore due to the WebContent process
        processing unrelated incoming synchronous IPC when waiting for a reply to one of its synchronous IPC
        to another process. In order to deal with this, we introduced a DoNotProcessIncomingMessagesWhenWaitingForSyncReply
        IPC::SendOption which we used on sendSync() calls where we knew re-entering would be unsafe. However,
        it turns out to be needed for a lot of the WebProcess's sync IPC and it is error-prone. In order to
        address the issue, we've decided to update the WebContent process behavior so that it processes all its
        IPC in order (not matter if synchronous or not) and thus so that we never dispatch unrelated synchronous
        IPC while waiting for a synchronous IPC reply, expect in cases where it would cause a deadlock.

        As a result, this patch also drops support for the DoNotProcessIncomingMessagesWhenWaitingForSyncReply
        IPC::SendOption which is no longer needed and has some code complexity.

        UIProcess should process incoming sync IPC from WebProcess when waiting for a sync IPC reply from it
        https://bugs.webkit.org/show_bug.cgi?id=189927

        Reviewed by Geoffrey Garen.

        UIProcess should process incoming sync IPC from WebProcess when waiting for a sync IPC reply from it
        in order to avoid deadlocks. This is not an issue currently because the WebProcess does process
        incoming sync IPC when waiting for a sync IPC reply. However, we plan to change this in the future
        in order to avoid bugs caused by re-entering WebCore at unsafe times.

        The reason the UIProcess previously did not do out of order sync IPC process was to avoid processing
        a synchronous policy decision IPC for a frameID it did not know about yet, due to the DidCreateMainFrame /
        DidCreateSubframe IPC messages being asynchronous. To address this issue, the decidePolicyForNavigationActionSync
        IPC handler now calls didCreateMainFrame() / didCreateSubframe() as needed if it does not know about
        the frame yet. Note that synchronous policy decisions are rare and are currently only needed by initial
        about:blank and fragment navigations.

        flag set to true. However, now that we stop setting this flag on the IPC
        connection from the WebProcess to the UIProcess, it would lead to those
        IPC messages getting processed out of order with regards to the
        DecidePolicyForNavigationAsync asynchronous IPC. DidCreateMainFrame would
        sometimes get processed *after* the DecidePolicyForNavigationAsync IPC
        and we would not know about the frameID yet.

        [WebAuthN] Make AuthenticatorManager
        https://bugs.webkit.org/show_bug.cgi?id=189279
        <rdar://problem/44116792>

        Reviewed by Chris Dumez.

        This patch introduces AuthenticatorManager which is the central of WebAuthentication that 1) handles
        web requests, 2) discovers authenticators, 3) manages authetnicators and 4) in the future interacts with UI.
        The lifetime of the AuthenticatorManager is managed by WebsiteDataStore such that it is almost a singleton
        per UI Process.

        1) Requests come from WebAuthenticatorCoordinatorProxy and then cached in AuthenticatorManager which will
        then distribute requests whenever a new authenticator is discovered.

        2) An ABC AuthenticatorTransportService is provided as an interface for AuthenticatorManager to invoke
        startDiscovery. Actual work will be done in corresponding derived classes, say, LocalService. LocalService
        is the one that discover attached platform authenticators, for example, TouchID or FaceID.

        Eache service is unique per AuthetnicatorManager, which means we will have at most 4 services, Local, USB,
        NFC, and BLE. The latter three will be implemented soon. Also, AuthenticatorManager serves as an observer to
        *Service, so the latter can inform the former whenever an authenticator is added or removed.

        When a new authenticator is discovered, the corresponding service will create an Authetnicator object that
        binds to the physical authenticator device through a *Connection object. There is no ABC for connection for
        now as I forsee every *Connection will be quite different. The *Connection object is the one that send/receive
        messages from the physicla device. So far, a LocalConnection is provided even though normally local authenticators
        are attached. This class is provided solely for separating UI and network traffic from LocalAuthenticator's
        request handling process. So we can override them in a mock test environment. I will talk about this in the
        next section.

        3) An ABC Authenticator is provided as an interface for AuthenticatorManager to distribute requests on. Requests
        will then be handled by the derived classes, say, LocalAuthenticator. Each authenticator object is a FSM that
        works asynchronously.

        For LocalAuthenticator, it has 4 states for MakeCredential: Init => RequestReceived => UserConsented => Attested => End,
        and 3 states for GetAssertion: Init => RequestReceived => UserConsented => End. In the transit from RequestReceived to
        UserConsented, it will invoke LocalConnection to talk to LocalAuthentication.framework that prompt users for TouchID
        or FaceID. And then the transit from UserConsented => Attested, it will invoke LocalConnection to talk to
        DeviceIdentity.framework that does Apple attestation. Most of the work are from the original LocalAuthenticator
        implementation, and this patch converts it to a FSM and simplify the callback and threading model.

        When a respond is ready, each authenticator will notify their observer which is the AuthenticatorManager.
        AuthenticatorManager will only reply to Web Process whenever there is a valid respond or a terminating error. Otherwise,
        the request will time out. I will explore the time out mechanism in a more detailed manner in Bug 189642.

        The above is a briefing of the AuthetnicatorManager architecture in functional. The asynchronous model is explained here:
        1) Since most discovery and request handling processes are asynchronous, I enforced them to be executed asyncrhonous in
        the interface of the ABC.
        2) There is no dedicated secondary threads here. However, underlying framework might decide to perform works on a dedicated
        thread and then execute the provided callback. Whenever such situation happens, the policy here is to wrap the actual callback
        into a callback that will post the actual callback back to the main thread and pass the wrapping callback to the APIs. Hence,
        weak pointers in the actual callback are guaranteed to work.
        3) Callbacks are used only if it is one way, and they are CompletionHandlers.
        4) Potential multi ways asynchronous operations are encapsulated in regarding Observer interfaces.

        Finally, let me explain how the mock test works:
        1) Mock testing is done in WebKitTestRunner instead of Internals because a considerable large portion of work is in UIProcess
        instead of WebProcess, says, the AuthenticatorManager.
        2) The basic idea is to override functionality of *Connection classes and then make them thin such that we can get the best
        possible coverage in auto tests.
        3) In order to enable layout tests to configure the Mock*Connection classes, a MockWebAuthenticationConfiguration struct is
        provided. A corresponding JS dictionary will be created by each test and passed from the TestRunner to the connection object.
        4) To bridge the above tunnel, a MockAuthenticatorManager is constructed. It is instrumented to return every error.
        5) Also, Mock*Service classes are made to mock the discovery process as well.
        6) Noted, every mock overrided methods are made thin.

        UIProcess should process incoming sync IPC from WebProcess when waiting for a sync IPC reply from it
        https://bugs.webkit.org/show_bug.cgi?id=189927

        Reviewed by Alex Christensen.

        UIProcess should process incoming sync IPC from WebProcess when waiting for a sync IPC reply from it
        in order to avoid deadlocks. This is not an issue currently because the WebProcess does process
        incoming sync IPC when waiting for a sync IPC reply. However, we plan to change this in the future
        in order to avoid bugs caused by re-entering WebCore at unsafe times.

        The reason the UIProcess previously did not do out of order sync IPC process was to avoid processing
        a synchronous policy decision IPC for a frameID it did not know about yet, due to the DidCreateMainFrame /
        DidCreateSubframe IPC messages being asynchronous. To address this issue, the decidePolicyForNavigationActionSync
        IPC handler now calls didCreateMainFrame() / didCreateSubframe() as needed if it does not know about
        the frame yet. Note that synchronous policy decisions are rare and are currently only needed by initial
        about:blank and fragment navigations.

        Extending the lifetime of a NetworkProcessProxy / StorageProcessProxy may cause it to have a stale WebProcessPool pointer
        https://bugs.webkit.org/show_bug.cgi?id=189851
        <rdar://problem/44696263>

        Reviewed by Alex Christensen.

        Extending the lifetime of a NetworkProcessProxy / StorageProcessProxy may cause it to have a stale WebProcessPool pointer:
        - NetworkProcessProxy::m_processPool
        - StorageProcessProxy::m_processPool

        Those data members are C++ references because it is expected that the WebProcessPool owns the NetworkProcessProxy and
        StorageProcessProxy. However, since NetworkProcessProxy / StorageProcessProxy are refcounted, it has happened that code
        extends the lifetime of those past their process pool, leading to stale prrocess pool usage. The fix for these crashes
        so far as been to ref the WebProcessPool instead of the NetworkProcessProxy / StorageProcessProxy. However, it is very
        tempting for people to simply ref the NetworkProcessProxy / StorageProcessProxy given that they are refcounted.
        For this reason, this patch updates NetworkProcessProxy / StorageProcessProxy so that they are no longer RefCounted
        and so that the WebProcessPool truly owns them via std::unique_ptr<>.

        Do not do early processing of incoming sync IPC unless we're waiting for a sync IPC reply
        https://bugs.webkit.org/show_bug.cgi?id=186941

        Reviewed by Alex Christensen.

        The comment was claiming we were processing incoming sync messages while waiting for a
        sync IPC reply to prevent deadlocks. However, the code was failing to check if we were
        waiting for a sync IPC reply. As a result, incoming sync IPC messages would get processed
        early no matter what, jumping the line. This was the source of the flakiness in the blob
        tests since the IPC to register the blob in the network process was async and the follow-up
        IPC to ask the network process for the blob size was sync. The sync message to get the blob
        size would jump the line and get processed before the async message to register the blob.
        As a result, the network process would not know about the blob yet and return size 0. Of
        course, this could happen if the network process was sending sync IPC at the time. However,
        the network process never sends any sync IPC and therefore, should never process incoming
        IPC messages out of order.

        Web Inspector: dock buttons disappear if Web Inspector goes fullscreen

        When a fullscreen Safari tab has a docked Inspector, and the "detach" button
        is clicked, Inspector goes into its own fullscreen window. In that window,
        there are no buttons for docking to side or bottom.

        It turns out that we always send setDockingUnavailable(true) if the inspector
        window is fullscreen. This eventually causes the inspector to reflect that
        by hiding the docking-related buttons.

        Extending the lifetime of a NetworkProcessProxy / StorageProcessProxy may cause it to have a stale WebProcessPool pointer
        https://bugs.webkit.org/show_bug.cgi?id=189851

        Reviewed by Alex Christensen.

        Extending the lifetime of a NetworkProcessProxy / StorageProcessProxy may cause it to have a stale WebProcessPool pointer:
        - NetworkProcessProxy::m_processPool
        - StorageProcessProxy::m_processPool

        Those data members are C++ references because it is expected that the WebProcessPool owns the NetworkProcessProxy and
        StorageProcessProxy. However, since NetworkProcessProxy / StorageProcessProxy are refcounted, it has happened that code
        extends the lifetime of those past their process pool, leading to stale prrocess pool usage. The fix for these crashes
        so far as been to ref the WebProcessPool instead of the NetworkProcessProxy / StorageProcessProxy. However, given how
        error-prone this is, this patch updates NetworkProcessProxy / StorageProcessProxy so that they forward their refcounting
        to the WebProcessPool.

        Handle the case where the InjectedBundle parameters do not successfully decode because they contain

        after the bundle initialiation function runs, which gives the embedding program the opportunity to
        register additional classes that are safe for serialization.
        
        Create a new 'decodeBundleParameters' method that contains the logic that used to live in 'initialize'.
        This new method returns 'true' if the serialization was successful, otherwise it returns false.

        Revise 'initialize' to call this new method and check the return value. If it fails, try decoding the

        This patch moves the management of 'attaching' the drawing area (Mac only concept) from web process
        to UI process. This is when we parent the layer tree to the view root layer. It also ensures that

        Update SuspendedPageProxy::m_process to be a RefPtr<> instead of a raw pointer, similarly
        to what we do in WebPageProxy. Relying on the WebProcessProxy to not get destroyed is
        risky as this crash demonstrates.

        * UIProcess/WebProcessProxy.cpp:
        (WebKit::WebProcessProxy::requestTermination):
        When a WebProcessProxy is terminated (by client or WebKit due to memory / cpu usage), call
        webProcessDidClose() on all SuspendedPages, similarly to what we do in case of a crash in
        processDidTerminateOrFailedToLaunch(). Failing to do so means that the SuspendedPageProxy
        may still have a pointer to this WebProcessProxy, even though WebProcessProxy::shutDown()
        has been called (which may destroy the WebProcessProxy).

        Resource Load Statistics: Add optional cap on partitioned cache max age

        These changes add the capability to set a max age cap for prevalent resources
        and consults it when retrieving cache entries. If an entry is capped and found
        to be too old, it will not be used but instead removed from the cache.

        This functionality is off by default because no cap is set by default.

        The ViewGestureController::removeSwipeSnapshot() implementation for iOS calls
        navigationGestureSnapshotWasRemoved() on m_webPageProxyForBackForwardListForCurrentSwipe.
        m_webPageProxyForBackForwardListForCurrentSwipe can differ from m_webPageProxy, and
        is a RefPtr<>. This means that this WebPageProxy's WKWebView might have been deallocated,
        in which case we'll crash when trying to use the pageClient in
        WebPageProxy::navigationGestureSnapshotWasRemoved(). To address the issue, we now return
        early in WebPageProxy::navigationGestureSnapshotWasRemoved() if m_isClosed is true,
        after resetting m_isShowingNavigationGestureSnapshot to false but *before* trying to use
        the pageClient. When a WKWebView is deallocated, it calls WebPageProxy::close(), which
        sets m_isClosed to true.

        Reviewed by Andy Estes.

        When WebKit2 was being developed, we initially made the C API WKPageSetPagePolicyClient and WKPageSetPageLoaderClient.
        When we released WKWebView, it was using WKNavigationDelegate, equivalent to WKPageSetPageNavigationClient.
        To support one or the other, we would use the navigation client if it was present, but if not we would fall back to the
        loader or policy client.  Since the loader and policy clients are now being minimally supported only until legacy
        software migrates to the navigation client, we are adding new functionality to the navigation client.
        Making the navigation client the default and using the loader or policy client only if they are present supports
        the legacy software and makes us have fewer forgotten null checks when adding new functionality to the navigation client.

        We need to keep the layer tree of the previous page alive and visible until we have something
        to render on the new page. With PSON on Mac this means that we should keep displaying the
        layer tree from the previus process.

        This patch moves the management of 'attaching' the drawing area (Mac only concept) from web process
        to UI process. This is when we parent the layer tree to the view root layer. It also ensures that
        the layer tree is not deleted too early on process swap and that it still eventually gets deleted.

        Many modern media control tests leak documents in testing
        https://bugs.webkit.org/show_bug.cgi?id=189437

        Reviewed by Darin Adler.

        In order to accurately detect leaks in media controls tests which use lots of
        SVGImages, we have to:
        - Fire a zero-delay timer after the postTask, in order for ImagesLoader's m_derefElementTimer
          to clear references to elements.
        - Have releaseCriticalMemory() call CachedResourceLoader's garbageCollectDocumentResources()
          to drop the last handle to the CachedResource for an SVGImage.
        - Call WKBundleReleaseMemory() after the GC and timer, since we need garbageCollectDocumentResources()
          to run again after that timer has fired.
        
        This should fix most of the spurious leak reports involving SVGImage documents.

        If navigation gestures are disabled while a swipe snapshot is visible,

        the snapshot.

        PSON: window.open() with 'noopener' should only process-swap cross-site, not cross-origin
        https://bugs.webkit.org/show_bug.cgi?id=189602
        <rdar://problem/44430549>

        Reviewed by Geoff Garen.

        The following fixes were made to our process swap on navigation logic:
        - Browsing contexts opened via window.open() with 'noopener' option now only same if
          they are cross-site, instead of doing a stricter cross-origin check.
        - Support process swapping when opening a new window via <a target="_blank" rel="noopener">
          that is cross-site.

        In order to support this, the following changes were made:
        - Stop passing a 'isCrossOriginWindowOpenNavigation' flag to the UIProcess when navigating because:
          - This is specific to window.open() and does not apply to other windows opened by DOM
          - This forces the origin check to happens on WebContent process side instead of relying on the
            one in WebProcessPool in the UIProcess
        - Pass the origin of the requester to the UIProcess when navigating, so that the WebProcessPool
          can use the requester's host for the cross-site check for the initial navigation in a new window
          created by DOM.
        - Add 2 flags to WebPageProxy which indicate if the page was created by the DOM and if any provisional
          loads have been committed. The WebProcessPool uses theses flags to recognize initial loads in
          new windows created by the DOM, so that it uses the requester's origin for the cross-site check.

        Move IndexedDB to Network Process

        <rdar://problem/44396973>

        Reviewed by Chris Dumez.

        We are going to eliminate storage process and move its functionality to network process. 
        The reasons why we want to do this:
        1. Lower resource usage of having an additional process for storage operations, especially
        memory. Single storage process takes about 5MB memory on macOS.
        2. Reduce latency of Service Workers. After enabling Service Workers, we've seen
        regression in app launch. The launch time of storage process is partly attributed to this:
        Service Workers delay page loading until receiving response from storage process.
        3. We choose network process because UI process may have broader access in file system
        that we don't want the storage operations to have.

        This patch is the first piece towards the goal. It mainly moves indexedDB from storage process
        to corresponding components of network process. Moving of Service Worker and stopping to 
        launch storage process will be done in following patches.

        We expect to see the higher cpu and memory usage of network process as it is taking more work,
        but the overall gain in memory and latency after we completely remove storage process should be 
        positive.

        Regression(PSON): setting window.opener to null allows process swapping in cases that are not web-compatible
        https://bugs.webkit.org/show_bug.cgi?id=189590
        <rdar://problem/44422725>

        Reviewed by Geoffrey Garen.

        If script calls window.open() without 'noopener' and the newly navigated window gets navigated cross-site,
        we are currently unable to process-swap because the opener has a WindowProxy handle to this new Window and
        may interact with it (which we currently do not support cross-process). We were dealing with this by not
        process-swapping if window.opener is not null. This works most of the time but is not sufficient because the
        opener may get nulled out, while the opener still has a valid WindowProxy handle to its openee.

        Therefore, we now also check for a flag indicating if the frame was opened via window.open() without
        'nooopener'. We still need to check if the browsing context has an opener for browsing context created
        via <a target="_blank"> for example (the opener does not have a handle to the new window but the openee
        has access to its opener).

        WebPageProxy::reportPageLoadResult can crash on some code paths
        https://bugs.webkit.org/show_bug.cgi?id=189568

        Reviewed by Chris Dumez.

        WebPageProxy::reportPageLoadResult (which is called from
        WebPageProxy::didFinishLoadForFrame) can sometimes crash when
        accessing m_pageLoadStart (a std::optional) in its unloaded state.
        Normally, m_pageLoadStart is initialized in
        WebPageProxy::didStartProvisionalLoadForFrame, which one would expect
        would be called before WebPageProxy::didFinishLoadForFrame. But that
        turns out to not always be the case. It's not apparent under what
        conditions didStartProvisionalLoadForFrame will not be called, but
        it's happening in the wild, leading to crashes now that std::optional
        asserts in release builds on bad accesses (see
        https://bugs.webkit.org/show_bug.cgi?id=189568).

        Fix this by checking m_pageLoadState on entry to reportPageLoadResult.

        ProcessSwap.BackWithoutSuspendedPage API test hits assertion under WebPageProxy::didCreateMainFrame()
        https://bugs.webkit.org/show_bug.cgi?id=189599

        Reviewed by Geoffrey Garen.

        The code in WebPageProxy::reattachToWebProcess() was re-initializing m_mainFrame unconditionally in case
        of a HistoryNavigation. The reason we need to initialize m_mainFrame in reattachToWebProcess() is if the
        process we're reattaching to already has a WebPage (with a main frame), in which case
        WebPageProxy::didCreateMainFrame() would not get called to initialize WebPageProxy::m_mainFrame.

        The process we're reattaching to can be in such a state only if it comes from a SuspendedPageProxy (we
        detached the WebProcessProxy from the WebPageProxy but kept the WebPage in the "suspended" WebProcess).
        It is true that we're only reattaching to a SuspendedPageProxy's process in the event of history
        navigations. However, it is not true that all history navigations will use a SuspendedPageProxy's process.
        For example, no SuspendedPageProxy may be available for the history navigation because the history
        was restored to a new view from disk, or because the WebBackForwardListItem no longer has a
        SuspendedPageProxy (we currently only keep a single SuspendedPageProxy for the last HistoryItem).

        Therefore, unconditionally initializating m_mainFrame in reattachToWebProcess() for history navigations
        is incorrect and we should instead check if we're reattaching to a SuspendedPage's process.

        Change is covered by ProcessSwap.BackWithoutSuspendedPage API test which is no longer crashes and
        existing Back/Forward PSON API tests which are still passing.

        Move IndexedDB to Network Process
        https://bugs.webkit.org/show_bug.cgi?id=189415

        Reviewed by Geoffrey Garen.

        We are going to eliminate storage process and move its functionality to network process. 
        The reasons why we want to do this:
        1. Lower resource usage of having an additional process for storage operations, especially
        memory. Single storage process takes about 5MB memory on macOS.
        2. Reduce latency of Service Workers. After enabling Service Workers, we've seen
        regression in app launch. The launch time of storage process is partly attributed to this:
        Service Workers delay page loading until receiving response from storage process.
        3. We choose network process because UI process may have broader access in file system
        that we don't want the storage operations to have.

        This patch is the first piece towards the goal. It mainly moves indexedDB from storage process
        to corresponding components of network process. Moving of Service Worker and stopping to 
        launch storage process will be done in following patches.

        We expect to see the higher cpu and memory usage of network process as it is taking more work,
        but the overall gain in memory and latency after we completely remove storage process should be 
        positive.

        Our logic in WebProcessPool::processForNavigationInternal() was wrongly using
        WebBackForwardList::currentItem() as source item of the navigation, instead of
        using Navigation::fromItem(). In case of back navigation, by the time
        processForNavigation() is called, the WebBackForwardList's currentItem has already
        been updated to be the target item, via a Sync IPC from the WebProcess. As a result,
        the source and target items would be the same in the following check:
        ` if (currentItem->itemID().processIdentifier == backForwardListItem->itemID().processIdentifier)`

        This would cause us to reuse the same process incorrectly. Our existing API test coverage
        did not catch this because our target HistoryItem usually has a SuspendedPage and we decide
        to use the SuspendedPage's process a few lines above in WebProcessPool::processForNavigationInternal().

        Clean up SuspendedPageProxy:
        1. SuspendedPageProxy does not need to be RefCounted. It is even dangerous given that WebPageProxy
           owns the SuspendedPageProxy and SuspendedPageProxy has a WebPageProxy& data member. We definitely
           do not want it to outlive its WebPageProxy.
        2. The SuspendedPageProxy destructor does not need to be virtual.
        3. Have WebBackForwardListItem keep a WeakPtr<SuspendedPageProxy> instead of a SuspendedPageProxy*.
           This is safer and avoid having to explicitly clear the pointer.
        4. m_finishedSuspending data member does not need a getter and is only needed if !LOG_DISABLED.

        This ensures the PageClient reference is always valid when used.

        Regression(PSON): "Swipe back" snapshot is missing when navigating back cross-process
        https://bugs.webkit.org/show_bug.cgi?id=189482
        <rdar://problem/44317222>

        Reviewed by Geoffrey Garen.

        The issue was that when we swap process on navigation, we:
        1. Call processDidTerminate() which calls resetState() and clears the displayed content
        2. Reattach the WebPageProxy to a new WebProcess
        3. Trigger the navigation
        4. Take the navigation snapshot

        When the navigation snapshot occurs at step 4, the view is already blank in the case of
        process swap. To avoid the issue, we take the navigation snapshot earlier, before calling
        processDidTerminate() and we suppress the next navigation snapshot as it would be blank.

        At some point, we will likely want to display the previous' WebProcess content longer,
        until the new WebProcess has something interesting to display. Once this is implemented,
        we'll likely be able to drop the early snapshotting logic.
