        This can happen when using single shared process model or when the process limit is reached in multiple process
        model. In this case, all pages in the same web process with accelerated compositing enabled share the same
        compositing thread. Every page sets its GL context as current when rendering a frame, but not when invalidating
        the threaded compositor when the page is closed. So, if a hidden tab is closed, the threaded compositor is
        invalidated and the GL resources of the current context (the visible page) are destroyed. This is also causing
        the blank pages issue when closing a tab related to another one, the current one stops rendering anything because
        its GL context has been released. We should make the threaded compositor context current when invalidating it.

        dlopen the bundle's executable before calling -[NSBundle load] since that will also do a bunch of other things we don't need
        https://bugs.webkit.org/show_bug.cgi?id=184904

        Reviewed by Geoffrey Garen.

        Loading an NSBundle does a lot of work to find the principal class inside
        the bundle. This means it walks all the objective C class names loaded
        by the bundle. Doing this is *really* expensive.
        
        Some users of the injected bundle define a WKBundleInitialize function.
        In such a case, we don't need the principal class, so we can skip loading
        the NSBundle. Now, before we load the bundle, we dlopen and dlsym looking
        for the WKBundleInitialize function. If we find it, we skip loading
        the bundle. If we don't find the WKBundleInitialize function, we fall
        back to loading the bundle and finding the principal class.
        
        This speeds up initializeWebProcess by ~70ms on my MBP.

        Don't create a new WebContent process when navigating to a blob object URL since doing so

        Reviewed by Ryosuke Niwa and Brady Eidson.

        This patch makes it so that WebProcessPool prewarms a process when process
        swap on navigation is turned on. When we do a process swap on navigation,
        we first try to grab a prewarmed process before creating a new one.
        
        We try to be smart about when to create these processes. The initial heuristic
        that this patch chooses is when we reach the DidFirstVisuallyNonEmptyLayout
        layout milestone. We're going to try to improve on this heuristic in:
        https://bugs.webkit.org/show_bug.cgi?id=184899
        
        This is a 40% progression on PLT with process swap on navigation turned on.

        This patch implements significant parts of https://github.com/whatwg/fetch/issues/687.
        We consume the From-Origin response header and only load the resource if:
        - The header is non-existent, empty, or invalid.
        - The header specifies 'same' and the resource's origin matches the originating
          document's origin and the origins up the frame tree.
        - The header specifies 'same-site' and the resource's eTLD+1 matches the originating
          document's eTLD+1 and the eTLD+1 of the documents up the frame tree.

        [CoordGraphics] Remove dead fixed layer code

        Reviewed by Michael Catanzaro.

        Drop the unused fixed layer handling  code in CoordinatedGraphicsScene.
        The m_fixedLayers container can be removed, along with the
        adjustPositionForFixedLayers() method that operated on that container.

        This was the only method that operated with the m_scrollPosition member
        variable and the contentsPosition argument that's passed to the
        CoordinatedGraphicsScene::paintToCurrentGLContext() method. Both of
        these are removed, along with the scrollPosition attribute on the
        CoordinatedGraphicsState struct.

        Reviewed by Michael Catanzaro.

        After r230950, current animation state for a given layer is also taken
        into account when determining whether or not the layer requires a
        backing store. For that to work properly, all the animation state has
        to be updated before the backing store work. This patch changes the
        order of helper method invocations in
        CoordinatedGraphicsScene::setLayerState() to address that.

        [CoordGraphics] Remove unused fixed layout functionality
        https://bugs.webkit.org/show_bug.cgi?id=184908

        Reviewed by Carlos Garcia Campos.

        Ports using the CoordinatedGraphics subsystem don't expose fixed layout
        support. As such, we're able to remove a lot of unused code and
        unnecessary USE(COORDINATED_GRAPHICS) special cases in generic sections
        in both WebCore and WebKit.

        Remove USE(COORDINATED_GRAPHICS) special-casing from the
        WebPage::setUseFixedLayout() method. This is not possible to enable for
        the GTK+ and WPE ports that use the CoordinatedGraphics subsytem via
        API. Removing all this unlocks removing considerable amounts of dead

        Reviewed by Ryosuke Niwa.

        This patch makes it so that WebProcessPool prewarms a process when process
        swap on navigation is turned on. When we do a process swap on navigation,
        we first try to grab a prewarmed process before creating a new one.
        
        We try to be smart about when to create these processes. The initial heuristic
        that this patch chooses is when we reach the DidFirstVisuallyNonEmptyLayout
        layout milestone. We're going to try to improve on this heuristic in:
        https://bugs.webkit.org/show_bug.cgi?id=184899

        If a client doesn't implement -[_WKInputDelegate _webView:focusShouldStartInputSession:] the default
        focus behavior only brings up the keyboard if it's already onscreen, the interaction is user driven,

        If a client implements _webView:focusShouldStartInputSession:, they don't have a good way to specifiy
        they'd like to fall back to the default behavior. This makes it difficult for a client to use the
        default in most cases, but sometimes allow programmatic focus from the page, for example.

        REGRESSION (r229828): web view doesn’t update or respond to resizing until client calls policy decision handler
        https://bugs.webkit.org/show_bug.cgi?id=184210
        <rdar://problem/39072354>

        Reviewed by Wenson Hsieh.

        r229828 tried to have some API tests happy on iOS by freezing the layer tree
        during the navigation policy decision. However, this is observable by the client
        application and a regression from when the policy delegate was synchronous.

        To address the issue, this patch reverts r229828 and instead updates the iOS
        API tests to wait for the next presentation update after navigating
        before interacting with the view.

        Revise the handling of cookie request headers so that we don't interact with them in the
        WebContent process. They are only needed for interaction with the server and the network
        process, so we should limit their scope to just the Network process.

        Instead, we should handle a token that represents the cookie headers in the WebContent
        process, which can be converted to the relevant cookie data in the network process when
        needed.

        A boolean is added for that purpose in NetworkResourceLoader.

        There is a small change of behavior in the way we return an error.
        Instead of returning a platformBadResponseError, we are now returning the error as computed by NetworkLoadChecker.

        Web Automation: add support for mouse/keyboard interaction sequences
        https://bugs.webkit.org/show_bug.cgi?id=184603
        <rdar://problem/39421839>

        Reviewed by Timothy Hatcher.

        Add new protocol methods and WebKit support for implementing the W3C Actions API.
        This is a generic command for sending low-level mouse, key, and touch events to
        test page behavior when performing drag-and-drop, gestures, or specific keydown/keyups.

        To implement this functionality, this patch adds SimulatedInputDispatcher, a class
        for dispatching input events asynchronously. Similar to the WebDriver specification,
        this is designed as a keyframing API. Callers set up several "input sources" such
        as keyboard or mouse, and then specify the states of that input source over time. The
        dispatcher calculates diffs between the previous and current keyframes and generates
        the appropriate events that would happen if a user caused the state transition.

        For example, if a mouse input source's state changes, the dispatcher sends synthetic mousemove,
        mousedown, or mouseup events depending on the pre- and post-state. This is uninteresting
        and overcomplicated for simple key and mouse presses, but it's really designed with an
        eye towards supporting mousemove interpolation and touch event interpolation in later patches.

        The strategy for dispatching events depends on the input source type; right now, these
        map directly to the existing platformSimulate{Mouse, Keyboard}Interaction methods. In
        the future, the dispatch strategy may be elaborated for interpolated mousemove events.

        This patch depends on support added in bug 184462.

        No tests yet. When this command is hooked up to a driver, the code will be exercised by
        W3C actions test suite, which is fairly complex at this point relative to end-user code.

        The dispatcher handles one interaction at a time. The interaction is described
        by an array of keyframes, and each keyframe has an array of states. The dispatcher
        transitions between keyframes by sequentially and asynchronously emitting events
        that cause each input source state to transition as desired. Keyframe transitions
        are additionally gated by a "maximum duration" timer. Each step that the dispatcher
        executes is asynchronous, so the dispatcher keeps most state in members and uses
        error argument lambdas as completion handlers for various async things.

        [Extra zoom mode] Add a mechanism to extend the height of the layout viewport in extra zoom mode

        Reviewed by Tim Horton.

        In extra zoom mode, at initial scale, fixed position elements may take up a large portion of the viewport. This
        leaves little room for non-fixed-position elements; to improve this experience, we introduce a mechanism to
        extend the height of the layout viewport. By default, the layout viewport size is determined by the FrameView's
        baseLayoutViewportSize, and passed into FrameView::computeUpdatedLayoutViewportRect in the client layer; in
        extra zoom mode, if the layout viewport is shorter than the document width, we try to double the height of the
        layout viewport and clamp to the document height if necessary.

        * Shared/WebPreferences.yaml:

        Add a new preference to determine the factor by which we should expand the height of the layout viewport. By
        default, this is 0 (no increase in layout viewport height); in extra zoom mode, this is 1, which means we'll
        increase the layout viewport's height by 1x the default height.

        bogus size, where the width is scaled to 320px but the height isn't. Instead, we should scale the layout height
        to match the new width here.

        Web Automation: simulated mouse interactions should not be done until associated DOM events have been dispatched
        https://bugs.webkit.org/show_bug.cgi?id=184462
        <rdar://problem/39323336>

        Reviewed by Carlos Garcia Campos and Tim Horton.

        Covered by existing layout tests and actions endpoints in WebDriver test suite.

        In preparation for implementing the W3C WebDriver command "Perform Actions", we need a way to
        know when a simulated mouse event has been fully processed by WebProcess and it is okay to continue
        to dispatch more simulated events.

        This patch makes mouse events go through a queue as they are delivered to WebPageProxy. The approach
        is very similar to how key events are handled. In the key event case, lots of WebEvents can come out
        of typing one keystroke, so these need to be queued up and retired one by one when the WebProcess has
        finished handling each event. In some mouse event cases---particularly fake mouse moves---there can
        also be more than one mouse event waiting to be handled by WebProcess.

        In the past, these queued mouse events were tracked with several member variables as different
        use cases emerged. These are all replaced with ordinary deque operations, such as peeking or
        checking the queue length.

        * Platform/Logging.h: Add logging channel for mouse events.
        * UIProcess/Automation/WebAutomationSession.cpp:
        (WebKit::AutomationCommandError::toProtocolString): Add type-safe helper class for command errors.
        In future patches we can hide knowledge of how this is sent over the protocol by relying more on
        the convenience constructors and .toProtocolString() method.

        (WebKit::WebAutomationSession::willShowJavaScriptDialog):
        This section needs adjustments. Since performMouseInteraction now depends on key events being processed
        prior to returning from the command, we need to abort any key event callbacks that are pending if an
        alert pops up as a result of sending a mousedown event. Any mouse events that are still queued will
        be handled when the alert is dismissed and the nested run loop exits.

        (WebKit::WebAutomationSession::mouseEventsFlushedForPage):
        (WebKit::WebAutomationSession::keyboardEventsFlushedForPage):
        Modernize this a bit. Don't spread knowledge about how commands are sent back out into event handling code.
        Our wrapper callbacks in performXXXInteraction handle the protocol-specific details of the response.

        (WebKit::WebAutomationSession::performMouseInteraction):
        Add code similar to performKeyboardInteractions so that the command doesn't finish until the mouse
        event has been fully handled. Unlike keyboards, sometimes mouse interactions don't turn into WebEvents
        so we also need to handle the case where there is nothing to be waited on because hit testing did
        not return a target to deliver the event to.

        (WebKit::WebAutomationSession::performKeyboardInteractions):
        Modernize a little bit to use generic callbacks rather than protocol-generated callbacks in the
        event waiting/handling code. Now it matches the types used for the mouse event case.

        * UIProcess/Automation/WebAutomationSession.h:

        The latter sends the next mouse event to WebProcess, and can be triggered in didReceiveEvent

        wrap-around without a _findStringCount. If a search is in progress, store the requested
        focus change in _focusedSearchResultPendingOffset, which will be applied once the search
        finishes.

        2. If wrap-around is about to happen but the find options do not allow it, we need to call
        FindClient::didFailToFindString(). Handle this by returning NO, which will tell
        -_focusOnSearchResultWithOptions: to call didFailToFindString() if a search is not in
        progress.

        With process swapping, the assumption that "back/forward items belong to a process" is invalid.

        All HistoryItem/WebBackForwardListItems now need to be uniquely identified across all processes,
        no matter which process they originated from, so there will never be a collision in the UIProcess.

        [Extra zoom mode] Programmatically changing focus when an element already has focus is a confusing experience

        <rdar://problem/39440642>

        Reviewed by Tim Horton.

        Currently on iOS, we allow element focus to present UI if the keyboard is already shown. In extra zoom mode,
        this would lead to a confusing experience when the focus form control overlay is disabled, since fullscreen
        input view controllers are swapped out from underneath the user. Currently, this also puts the UI process into a
        bad state where the focused form control overlay is active, but still hidden. This patch makes some tweaks to
        input view controller handling in the UI process to address these issues, and also adds WebKitTestRunner support
        for simulating interactions with select menus in extra zoom mode. See comments below for more detail.

        In extra zoom mode, when changing focus from one assisted node to another, only allow the second node to be
        assisted if the focused form control overlay is being shown. Otherwise, (i.e. when a fullscreen input view
        controller is being presented), don't allow focus to start an input session.

        Additionally, make a minor tweak to allow the previous node to blur, even if we are not showing the keyboard for
        the new focused element. Without this adjustment, in the case where the page has programmatically focused
        another element while a fullscreen input view controller is presented, we'll show the old view controller for
        the new focused element.

        (-[WKContentView presentViewControllerForCurrentAssistedNode]):
        (-[WKContentView dismissAllInputViewControllers:]):

        Currently, when a fullscreen input view controller is presented, the web process gets backgrounded. This
        prevents event handlers from executing, which leads to strange behaviors in many cases (for instance: if we
        have a multiple select, and the "change" event handler blurs the select, the user may check or uncheck multiple
        items, but only the first change will actually take effect).

        To fix this, we maintain a background activity token while presenting an input view controller.

        (-[WKContentView focusedFormControlViewDidBeginEditing:]):

        Start hiding the focused form overlay when re-presenting an input view controller. This allows us to bail from
        showing fullscreen input UI for another focused element if focus programmatically changes while the current
        fullscreen input view controller is presented, due to the -isHidden check in -_startAssistingNode:.

        Implement the text legibility heuristic alluded to in r230506 by iterating through text runs in the document (up

        represents a character.

        The first and second text legibility zoom scales are then computed based on the zoom scales needed to
        make 50% and 90% of the text legible, respectively. Here, a zoom scale that makes text legible is such that the
        text would have an apparent font size of a hard-coded constant (currently, 12) after zooming. This means the
        first and second text legibility scales may end up being close to one another, or even the same (in the case
        where there is only a single font size in the entire document). In this case, we just snap the first scale to
        the second, so that double tapping will only toggle between two zoom scales. In another case where the document
        has no text (e.g. an image document), we just fall back to a zoom scale of 1.

        is activated already when the selection rects change, so there is no reason to activate it now. This has likely worked
        in the past because this selection assistant was only for editable text, which would immediately set a caret, which

        Web Automation: simulated mouse interactions should not be done until associated DOM events have been dispatched

        <rdar://problem/39323336>

        Reviewed by Carlos Garcia Campos and Tim Horton.

        Covered by existing layout tests and actions endpoints in WebDriver test suite.

        In preparation for implementing the W3C WebDriver command "Perform Actions", we need a way to
        know when a simulated mouse event has been fully processed by WebProcess and it is okay to continue
        to dispatch more simulated events.

        This patch makes mouse events go through a queue as they are delivered to WebPageProxy. The approach
        is very similar to how key events are handled. In the key event case, lots of WebEvents can come out
        of typing one keystroke, so these need to be queued up and retired one by one when the WebProcess has
        finished handling each event. In some mouse event cases---particularly fake mouse moves---there can
        also be more than one mouse event waiting to be handled by WebProcess.

        In the past, these queued mouse events were tracked with several member variables as different
        use cases emerged. These are all replaced with ordinary deque operations, such as peeking or
        checking the queue length.

        * UIProcess/Automation/WebAutomationSession.cpp:
        (WebKit::AutomationCommandError::toProtocolString): Add type-safe helper class for command errors.
        In future patches we can hide knowledge of how this is sent over the protocol by relying more on
        the convenience constructors and .toProtocolString() method.

        (WebKit::WebAutomationSession::willShowJavaScriptDialog):
        This section needs adjustments. Since performMouseInteraction now depends on key events being processed
        prior to returning from the command, we need to abort any key event callbacks that are pending if an
        alert pops up as a result of sending a mousedown event. Any mouse events that are still queued will
        be handled when the alert is dismissed and the nested run loop exits.

        (WebKit::WebAutomationSession::mouseEventsFlushedForPage):
        (WebKit::WebAutomationSession::keyboardEventsFlushedForPage):
        Modernize this a bit. Don't spread knowledge about how commands are sent back out into event handling code.
        Our wrapper callbacks in performXXXInteraction handle the protocol-specific details of the response.

        (WebKit::WebAutomationSession::performMouseInteraction):
        Add code similar to performKeyboardInteractions so that the command doesn't finish until the mouse
        event has been fully handled. Unlike keyboards, sometimes mouse interactions don't turn into WebEvents
        so we also need to handle the case where there is nothing to be waited on because hit testing did
        not return a target to deliver the event to.

        (WebKit::WebAutomationSession::performKeyboardInteractions):
        Modernize a little bit to use generic callbacks rather than protocol-generated callbacks in the
        event waiting/handling code. Now it matches the types used for the mouse event case.

        This can lead to sessions getting stuck and safaridriver is unable to request a new session.

        Expose the -terminate method as SPI. This disconnects the remote connection and then notifies
        the session delegate that the remote disconnected. At that point, Safari can uninstall
        the session from the process pool and tear down other session state.

        Introduce SuspendedPageProxy to keep old web processes around after their WebPageProxy has been swapped to a new one.
        https://bugs.webkit.org/show_bug.cgi?id=184559

        Reviewed by Alex Christensen.

        Before this patch, when a WebPageProxy navigates and is swapped to a new process, the old process almost always goes away.

        This is not desirable for a few reasons:
        1 - We can't keep the PageCache working for back/forward scenarios
        2 - We throw away a "foo.com" web process, meaning the next time we need to host a "foo.com" web page we have to launch
            and initialize a new web process.

        This patch adds a SuspendedPageProxy object to keep around the old web process and to manage communication with it.

        For now, a WebPageProxy keeps exactly one "suspended page" representing the most recently visited page and its process.
        Additionally, that process is never reused.

        So no benefit is achieved with this patch, but it enables future benefits.

        [Extra zoom mode] Support pushing input view controllers onto the navigation stack
        https://bugs.webkit.org/show_bug.cgi?id=184397
        <rdar://problem/39265294>

        Reviewed by Timothy Hatcher.

        Currently, all input view controllers in extra zoom mode are presented modally. However, the latest iteration of
        the HI specification depicts most of these view controllers (with the exception of time pickers) being presented
        and dismissed via navigation stack. Since WebKit's iOS API surface doesn't force clients to embed WKWebViews
        within a view controller with a corresponding UINavigationController, we cannot always guarantee that UI
        presented when focusing form controls in a web view will be pushed onto the navigation stack; as such, the
        approach taken in this patch will automatically allow WKWebView clients that already embed WKWebViews within a
        UINavigationController to hook into this behavior, with modal presentation as a fallback.

        At a high level, this patch makes the following tweaks to implement this behavior:

        1. Store the currently presented view controller using a single member variable
           (_presentedFullScreenInputViewController) instead of having one for each type. This makes bookkeepping around
           which view controller to present or dismiss much more straightforward.

        2. Replace WKFocusedFormControlViewController with just WKFocusedFormControlView. This addresses problems with
           pushing an input view controller onto the navigation stack after presenting the focused form control view
           controller modally. Now, we'll only need to present or push one view controller on the navigation stack.

        3. Remove -handleWheelEvent: forwarding to date and time pickers. Pushing date picker view controllers onto the
           navigation stack rather than presenting them modally means that we end up in a state where neither the
           WKContentView nor WKTimePickerViewController are first responder, which renders time pickers unusable.
           Instead, have the WKTimePickerViewController actually become first responder when presenting.

        4. Lastly, and most importantly: change -presentViewControllerForCurrentAssistedNode and
           -dismissAllInputViewControllers to try and push onto a navigation stack if possible, and fall back to modal
           presentation.

        * UIProcess/ios/WKContentViewInteraction.h:

        Remove the separate member variables for each type of input view controller, and instead have one to keep track
        of the current (and only) presented input view controller.

        Completely remove WKFocusedFormControlViewController; instead, just directly place the focused form overlay in
        the WKWebView's hierarchy. In the case where we have a navigation stack to push to, we can no longer modally
        present the focused form overlay as a separate view controller using the UINavigationController, and then
        immediately push the input view controller on top of the navigation stack, since the navigation stack isn't
        updated until after the animation of the focused form overlay presentation is complete. Rather than hack around
        this limitation by dispatch_after-ing after presenting the overlay's view controller, we should just make the
        overlay a view. This also fixes the case where a client embedding a WKWebView that is smaller than the bounds of
        the screen will no longer see the entire screen dim when focusing an input, but instead, just the web content.

        Currently, AssistedNodeInformation only sends the `title` of input elements to the UI process. This means that
        any information requested in the UI process that is dependent on the `title` of the focused element is broken
        in the case of select elements. An existing example of this is the title of the table view controller used to
        present select menus on iPad.

        To fix this, we simply send the `title` of the focused element across, as long as the focused element is an
        HTMLElement. This ensures that there's label text when focusing unlabeled select elements with titles in extra
        zoom mode, and also fixes a currenly broken codepath where we show the title of the select in the presented view
        controller's title.

        [Extra zoom mode] Add a mechanism to zoom to fixed scales when double tapping in extra zoom mode
        https://bugs.webkit.org/show_bug.cgi?id=184435
        <rdar://problem/38726260>

        Reviewed by Dean Jackson.

        Adds support for an alternate codepath when computing a zoom rect when double tapping that doesn't take the hit-
        tested node into account, and instead cycles the zoom scale between 2 fixed values (in addition to the initial
        scale). In the next patch, these fixed scales will be determined by computing zoom scales needed to make most of
        the text on the page legible (i.e. the first text legibility zoom scale), and another to make all of the text on
        the page legible, with the exception of outliers (this is the second text legibility zoom scale).

        See comments below for more detail.

        (WebKit::ViewGestureGeometryCollector::dispatchDidCollectGeometryForSmartMagnificationGesture):

        Rename the boolean `isReplacedElement` argument to `fitEntireRect` instead. The UI process only uses this on iOS
        to determine whether or not to fit the entire element rect to the viewport and add padding. This patch renames
        this variable because we are not zooming to a replaced element in the case where text legibility on the page
        (rather than element geometry) is being used to figure out the zoom scale, but we still want to fit the entire
        target rect to the viewport.

        (WebKit::ViewGestureGeometryCollector::collectGeometryForSmartMagnificationGesture):

        If text legiblity zoom scaling is preferred, then compute first and second-level text legibility zoom scales to
        zoom to upon double tap (where the second zoom scale is greater than the first). To choose a target zoom
        scale, choose the lowest target zoom scale that is at least a small amount less than the current scale. If
        neither of the two scales fulfill this description, then zoom back out to the initial scale. This has the effect
        of consistently cycling between all three zoom scales as the user double taps.

        (WebKit::ViewGestureGeometryCollector::computeTextLegibilityScales):

        Introduce a new helper method that computes and caches target scales to zoom to when double tapping to zoom. If
        a cached pair of target scales is already present, it skips this computation and immediately returns it.

        (WebKit::ViewGestureGeometryCollector::computeZoomInformationForNode):
        (WebKit::ViewGestureGeometryCollector::computeMinimumAndMaximumViewportScales const):

        Factor out logic to compute min and max zoom scales into a separate helper, and call it from both
        computeZoomInformationForNode and computeTextLegibilityScales.

        WebCore::EventHandler::targetPositionInWindowForSelectionAutoscroll is directly accessing NSScreen
        https://bugs.webkit.org/show_bug.cgi?id=184344
        <rdar://problem/39224969>

        Reviewed by Per Arne Vollan.

        The implementation of targetPositionInWindowForSelectionAutoscroll uses the display ID to get the
        screen boundaries of the current display. This causes a bunch of interaction with NSScreen that
        we do not want to allow in the WebContent process.

        Instead, we should just use the cached screen information the WebContent process already possesses.

        This patch makes the following changes:
        1. We now retrieve the screen rect of the page's display from the cache, rather than interacting with
           the WindowServer directly.
        2. Add a new 'toUserSpaceForPrimaryScreen' so we don't have to deal with a nil NSWindow when computing
           the user space version of the coordinates. A nil Window just means we want to get coordinates in
           terms of the primary display.
        3. Keep track of the primary display so we can refer to it later.
        4. Modify the IPC messages to include the primary display's ID so we can easily access it later.
        5. Modify the PlatformScreen methods to actually use the primary display when appropriate, rather
           than whichever screen happened to hash to the lowest value.

        WebContent process sometimes hangs in WebProcess::ensureNetworkProcessConnection
        https://bugs.webkit.org/show_bug.cgi?id=184326

        Reviewed by Chris Dumez.

        The hang was caused by UI process never sending the reply back to GetNetworkProcessConnection
        due to m_pendingOutgoingMachMessage being set and the event handler for DISPATCH_MACH_SEND_POSSIBLE
        never getting called. This is because the event handler registration happens asynchronously,
        and may not have completed by the time we send the first IPC to the web content process
        in which case it can timeout and we may never get the callback.

        Fixed the hang by waiting for the event handler registration to be completed using
        dispatch_source_set_registration_handler. To do this, this patch adds a new boolean instance variable,
        m_isInitializingSendSource, to Connection which is set to true between the time mach port is created
        and until the event handler registration has been completed. platformCanSendOutgoingMessages returns
        false while m_isInitializingSendSource is set to prevent the attempt to send messages like we do when
        m_pendingOutgoingMachMessage is set to true.

        https://bugs.webkit.org/show_bug.cgi?id=184293

        Reviewed by Alex Christensen.

        The problem is that after willSendRequest callback changes the request, the load is cancelled while
        transitioning to committed state. This happens because the load is not waiting for the response policy check, so
        it continues and when transitioning to committed, FrameLoader::closeURL() invalidates the current policy check
        that causes a load failure. The new request returned by the API doesn't have any requester, so it's no longer
        considered a main resource load. In the network process the resource load task doesn't wait for the response
        policy and continues the load, sending the data to the web process. Once the first data is received, the load
        transitions to commit, but the response policy check is still ongoing. This can only happen when using the C API
        (I don't know about the Cocoa API), but not with the GLib API because it doesn't allow to create a new request,
        only to modify the passed in one. With the C API we loss other internal things of the request like the priority,
        but I guess the most important one is the requester.

        that a compromised WebProcess will not be able to bypass any of these.
        In the future, NetworkProcess should get the content blocker identifier directly from the WebPageID attached to the request.

        Covered by existing beacon+content blocker tests.

        Did some refactoring to add a typed content blocker identifier.
        Once NetworkProcess fetches a given content blocker, the content blocker will send any modification to NetworkProcess.
        Introduced NetworkContentRuleListManager to handle the content blockers in NetworkProcess.

        Process swapping on navigation needs to handle server redirects.
        <rdar://problem/38690465> and https://bugs.webkit.org/show_bug.cgi?id=184142

        Reviewed by Alex Christensen.

        The same rules we apply to process swapping for basic navigations need to apply
        to server redirects as well.

        There's three interesting cases we need to support that are covered by new API tests:
        1 - The initial load in a WKWebView redirects cross-origin.
        2 - A WKWebView is showing content from a.com, we start a load to b.com, and that redirects to c.com
        3 - A WKWebView is showing content from a.com, we start a load to a.com, that that redirects to b.com.

        Supporting all 3 of these brought their own little challenges.

        By teaching Navigation objects more about redirects I was able to support all 3 cases.

        The same rules we apply to process swapping for basic navigations need to apply
        to server redirects as well.

        There's three interesting cases we need to support that are covered by new API tests:
        1 - The initial load in a WKWebView redirects cross-origin.
        2 - A WKWebView is showing content from a.com, we start a load to b.com, and that redirects to c.com
        3 - A WKWebView is showing content from a.com, we start a load to a.com, that that redirects to b.com.

        Supporting all 3 of these brought their own little challenges.

        By teaching Navigation objects more about redirects I was able to support all 3 cases.

        [Extra zoom mode] Zoom level is sometimes excessive when zooming to focused form controls
        https://bugs.webkit.org/show_bug.cgi?id=184222
        <rdar://problem/39063886>

        Reviewed by Timothy Hatcher.

        Upon interactively focusing an element, we zoom and scroll to reveal that element. The heuristics introduced in
        <https://trac.webkit.org/r168744> work by computing a target scale, and then a point to zoom to given that
        scale. Currently, this scale is dependent on the computed font size of the form control, such that the form
        control would be scaled to have an effective font size of 16.

        However, in extra zoom mode, applying these same heuristics (ironically) results in excessive zoom levels, since
        scaling the font up to 16 would cause most form controls to zoom so far in that we lose context of surrounding
        elements such as labels and other form controls; the fact that the element is highlighted by the focused form
        control overlay makes this even more confusing, since part of the focus overlay highlight rect often ends up
        outside the viewport.

        To fix this, we make a couple of tweaks to focus rect zooming in extra zoom mode. (1) Instead of computing
        target zoom level based on font size, try to zoom such that the focused element rect fills up most of the
        viewport (similar to double-tap zooming). This ensures that the focused form control overlay's highlight rect
        makes sense in most cases, with few exceptions (e.g. the element frame is larger than the viewport). (2)
        Introduce a minimum legible font size of 11, and compute the minimium scale needed such that the form control
        font would appear to be at least this legible font size. Then, clamp the target scale chosen by (1) to this
        minimum scale.

        One additional consideration for (1) is that naively scaling to fit the element rect to the viewport (with some
        fixed margins) would cause the viewport scale to always change when moving focus between form controls of
        different dimensions, even if the current scale is more or less appropriate for all the focusable elements. To
        address this, instead of computing a single target zoom scale for an element rect, compute a range of possible
        target zoom scales (where the minimum and maximum values depend on the margin we add around the element rect).
        If the current scale already falls within this target scale range, then we won't bother adjusting the scale at
        all (unless the font size is too small — see (2)). If the current scale falls outside the target scale range, we
        then make the minimal adjustment needed to ensure that the element rect fits well within the viewport without
        being too small.

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

        Move some logic around so that the target scale is computed after computing the visible size. Also renames some
        constants local to this function (WKWebViewStandardFontSize, kMinimumHeightToShowContentAboveKeyboard,
        UIWebFormAnimationDuration, CaretOffsetFromWindowEdge) such that they now share a consistent naming style.

        It is possible for mach_port_allocate to return an error, but we rarely check its return value. The value
        of the argument passed to mach_port_allocate is not guaranteed to be valid when it returns an error, so
        there is a potential for us to try to use invalid ports.

        Web Automation: support enter/exit fullscreen and hide/restore window operations
        https://bugs.webkit.org/show_bug.cgi?id=182837
        <rdar://problem/37580732>

        Reviewed by Tim Horton.

        The W3C specification is more explicit about when to exit fullscreen and
        restore the window for a browsing context. So, WebKit needs to have support
        for performing these operations on behalf of a driver.

        Based on prototyping, it is sufficient to use a JavaScript atom to enter
        fullscreen mode. This is included in the patch as EnterFullscreen.js and
        can be used to implement the §10.7.5 Fullscreen Window command.

        Other window operations cannot be peformed from JavaScript, so we need to
        delegate these operations to the session client (i.e., Safari).
        This patch adds session client callouts for restoring, minimizing, and
        switching to a browsing context.

        Exiting fullscreen happens implicitly (per specification) when setting a
        window frame without an actual frame, or when switching/restoring/minimizing a window.
        If needed, a driver can call Set Window Rect in this way to unfullscreen a context.
        Similarly, a driver can restore a minimized window using Set Window Rect.

        We currently have separate presentation and dismissal helpers for each type of view controller corresponding to

        the focused form control overlay.

        This refactoring allows us to then adjust the timing of first responder restoration logic, such that the focused
        form control view controller can receive forwarded events from the web view. See below for more detail.

        This is currently just used for specifying tab vs window, but could
        also be used for things like toggling certain browser chrome or features.

        There is no guarantee that the client has a notion of tabs vs windows,
        so this option is purely advisory and should not cause the command to
        fail if it cannot be honored.

        This behavior caused by specifying this option is client-specific, so no

        [GTK][WPE] Add API to convert between DOM and JSCValue
        https://bugs.webkit.org/show_bug.cgi?id=183448

        Reviewed by Michael Catanzaro.

        Add methods to get a JSCValue for a WebKitDOMObject and to create a WebKitDOMNode from a JSCValue. Deprecate
        most of the GTK+ DOM bindings API and move the non-deprecated parts to glib dir to be exposed by WPE too.

        Default the CoordinatedGraphicsScene destructor.

        The m_scrollPosition member variable is unused in this class, while the

        Web Automation: remove unnecessary member variable WebAutomationSession
        https://bugs.webkit.org/show_bug.cgi?id=183971

        Reviewed by Timothy Hatcher.

        The concept of the "active" browsing context is something in the WebDriver
        specification, but we were a bit too literal when first implementing this.
        There's no actual need for this on the browser side since most commands
        require implicitly switching to the target window passed in with the
        Automation command. The driver, however, still needs to track the current
        browsing context and current top-level browsing context.

        For returning whether a browsing context is active,  we can just look at
        the page's activity state to know whether the page is active or not. For
        a normal browser, only one page is going to be visible and focused at a time.

        Add new SPI hooks to _WKInputDelegate allowing internal clients to provide a view that gives additional context
        when editing form controls, on top of the default label or placeholder text displayed by WebKit. The height
        delegate is invoked first, giving the client an opportunity to lay out the context view to fit the given size;
        the actual view is then queried.

        If the view changes, clients may tell WebKit to reload the context view via SPI on WKFormInputSession; this call
        to reload is plumbed through to the currently presented list view controller (at the moment, this is only the

        Reviewed by Wenson Hsieh.

        Without asynchronous policy delegates, when the client requests a navigation, we would:
        1. Do a synchronous navigation policy check
        2. If the client allows the navigation, start the provisional load

        Starting the provisional load would freeze the layer tree until first meaningful
        layout via WebFrameLoaderClient::provisionalLoadStarted() -> WebPage::didStartPageTransition().

        When constructing a WebView and then requesting a load right away. This would make sure
        we do not commit a layer tree for the initial about:blank page because the layer tree
        would be frozen until we have something meaningful to show for the following load.

        However, with asynchronous policy delegates, we are able to do a layer tree commit
        during the asynchronous navigation policy check because the layer tree is not frozen
        yet (provisional load has not started) and the process is not stuck on synchronous
        IPC. When constructing a WebView and then requesting a load right away, this would
        allow a layer tree commit for about:blank to happen before we've even started the
        load. This would cause some API tests to fail on iOS.

        To address the issue, we try and maintain pre-existing behavior by freezing the
        layer tree during navigation policy decision.

        port. Add alternative functions using the new JSC GLib API. We no longer need to keep a global context attached
        to every view. We can simply create a temporary global context on demand and release it after 1 second. This
        also allows us to remove WebPageProxy::javascriptGlobalContext() and all the related code.

        There are significant bugs to be resolved and significant optimizations to be made.

        ServiceWorkerClientFetch::didReceiveData should check for m_encodedDataLength
        https://bugs.webkit.org/show_bug.cgi?id=183668

        Reviewed by Chris Dumez.

        Crash happens when releasing a RefPtr<SharedBuffer> buffer that is null.
        It happens because ServiceWorkerClientFetch can call m_loader->didReceiveBuffer at two different places.
        Either when receiving an IPC call or as part of completion handler for the response validation check.
        At each call site, we release the buffer to pass it to the loader and we set m_encodedLength to zero.
        The fix is to add the m_encodedLength check like done in the case of response validation check completion handler.

        [iOS WK2] Hit-testing fails when specifying a large top content inset
        https://bugs.webkit.org/show_bug.cgi?id=183648
        <rdar://problem/38421894>

        Reviewed by Tim Horton.

        Currently, in the process of computing unobscured content rect in the UI process on iOS, we subtract away parts
        of the view that are obscured by insets (e.g. MobileSafari's chrome). The helper method -[WKWebView
        _computeContentInset] is intended to compute these obscuring insets around the view, but it takes scroll view
        insets into account. This means that if WKWebView's inner scroll view has content insets, we'll end up shrinking
        the unobscured content rect as if the insetted region obscures the viewport; this causes visible content on the
        page to be uninteractible, since WKWebView erroneously thinks it's obscured.

        To address this, we rename _computeContentInset to _computeObscuredInset, and make it _not_ affected by the
        scroll view's content insets. From code inspection and testing, all but one of the former call sites of
        _computeContentInset really need the obscured inset instead (see below). The one exception, -[WKWebView
        _adjustedContentOffset:], takes a scroll position from the page and maps it to a content offset in the inner
        UIScrollView (see below for more details).

        Tests:  ScrollViewInsetTests.InnerHeightWithLargeTopContentInset
                ScrollViewInsetTests.InnerHeightWithLargeBottomContentInset
                ScrollViewInsetTests.RestoreInitialContentOffsetAfterCrash
                ScrollViewInsetTests.RestoreInitialContentOffsetAfterNavigation

        (-[WKWebView _setHasCustomContentView:loadedMIMEType:]):
        (-[WKWebView _initialContentOffsetForScrollView]):

        See -_contentOffsetAdjustedForObscuredInset: below.

        (-[WKWebView _contentOffsetAdjustedForObscuredInset:]):

        Formerly -_adjustedContentOffset:. -_contentOffsetAdjustedForObscuredInset: no longer takes scroll view content
        inset into account, and only cares about insets that obscure the view. This means that the scroll position
        (0, 0) in the document now maps to the content offset in the inner UIScrollView, such that the top of the page
        is aligned with the top of the viewport.

        However, many call sites of -_adjustedContentOffset: were intended to compute the initial, top-left-most content
        offset in the scroll view to scroll to when resetting the web view (i.e., they pass in CGPointZero for the
        scroll position). An example of this is the scroll position to jump to after web content process termination, or
        the scroll position after main frame navigation. In these cases, we actually want to jump to the top of the
        scroll view, so we do want to use the version of the computed content insets that accounts for scroll view
        insets.

        Since these cases are limited to finding the top-left-most scroll position, we pull this out into a separate
        helper method (-_initialContentOffsetForScrollView) and replace calls to
        `-[self _adjustedContentOffset:CGPointZero]` with this instead.

        (-[WKWebView _computedObscuredInset]):

        A version of -_computeContentInset that doesn't care about scroll view insets. Used whereever we need to account
        for obscured insets rather than the combination of content insets and unobscured insets (e.g.
        -_initialContentOffsetForScrollView).

        (-[WKWebView _processDidExit]):
        (-[WKWebView _didCommitLayerTree:]):

        (-[WKWebView scrollViewWillEndDragging:withVelocity:targetContentOffset:]):
        (-[WKWebView _updateVisibleContentRects]):
        (-[WKWebView _navigationGestureDidBegin]):

        In all these places where we inset the view bounds to compute the unobscured region of the viewport, it doesn't
        make sense to additionally inset by the scroll view's content insets, since (1) the scroll view's content insets
        don't obscure the viewport, and (2) it's perfectly valid for the inner scroll view to have arbitrarily large
        content insets.

        (-[WKWebView _adjustedContentOffset:]): Deleted.

        Renamed to -_contentOffsetAdjustedForObscuredInset:.

        (-[WKPDFView _scrollToFragment:]):

        This helper figures out which content offset to scroll to, given the y-origin of a page in a PDF document. If
        insets are added to the scroll view, we end up scrolling to the wrong content offset since we'll add the height
        of the top content inset (imagine that the top content inset is enormous — then we'll scroll an amount equal to
        the top content inset _past_ the point where the y-origin of the page is at the top of the viewport).

        It turns out the fix in https://bugs.webkit.org/show_bug.cgi?id=183577
        wasn't enough to address the compatibility issues with popups. Some of
        them just detect their unpartitioned cookies, auto-dismiss themselves,
        and expect their unpartitioned cookies to be available under the opener
        afterwards. We should grant them access if the popup's domain has had
        user interaction _previously_.

        Note that we still need https://bugs.webkit.org/show_bug.cgi?id=183577
        because if the popup's domain has not received user interaction
        previously, we will not grant it storage access on just the window open.

        now that policy decisions can be made asynchronously.

        However, one of the 2 code paths in NetworkProcess side (code path when
        the resource is already in the HTTP disk cache) failed to wait for the
        ContinueDidReceiveResponse IPC before sending over the data to the WebProcess.

        Ensure that ServiceWorkerFetchClient::m_isCheckingResponse is set before code that depends on it
        executes. This bit was set by code that's posted to the runloop using 'callOnMainThread' in
        ServiceWorkerFetchClient::didReceiveResponse. But when didReceiveResponse is executing, tasks for
        handling didReceiveData, didFail, or didFinish may already have been posted to the runloop, and in
        that case would execute before m_isCheckingResponse gets set, and then incorrectly fail to 
        early-out. Fix this by directly setting m_isCheckingResponse in didReceiveResponse.

        Create CA layer contexts with +remoteContextWithOptions.
        https://bugs.webkit.org/show_bug.cgi?id=182747

        Reviewed by Brent Fulgham.

        CA layer contexts (CAContext) are currently created with +contextWithCGSConnection, which is
        using the main WindowServer connection to create the context. Instead, the contexts can be
        created with +remoteContextWithOptions, which does not use the main WindowServer connection.
        This is a step towards limiting the access the WebContent process has to the window server.
        To make the +remoteContextWithOptions call succeed, the sandbox has to be modified to allow
        access to CARenderServer. Also, access to the WindowServer should be denied by calling
        CGSSetDenyWindowServerConnections(true) before entering the sandbox. This is planned to do
        in a follow-up patch. The call to +remoteContextWithOptions will open up WindowServer
        connections, since the WindowServer is the system default CA render server, but these
        connections come with limited WindowServer exposure. In addition, we need to open up the
        sandbox for accessing some IOKit properties.

        https://bugs.webkit.org/show_bug.cgi?id=183489
        <rdar://problem/38267517>

        WebKit calls -[NSFilePromiseReceiver receivePromisedFilesAtDestination:...] with
        NSTemporaryDirectory() as the destination for receiving file promise drops. AppKit attempts
        to issue a sandbox extension for this directory, but for security reasons App Sandbox
        refuses to do so for NSTemporaryDirectory() itself. As a result, AppKit will call our reader
        block with a nil error and a valid file URL, but no file will actually exist at that URL.

        In order for App Sandbox to grant issuing the sandbox extension needed by AppKit, we need to
        use some other destination directory. This patch uses FileSystem::createTemporaryDirectory()
        to securely create a unique temporary directory inside NSTemporaryDirectory() for use as the
        drop destination.

        <rdar://problem/38225994>

        Reviewed by Tim Horton.

        Currently, when presenting an input view controller in extra zoom mode, if the web view loses first responder
        status, we will blur the focused element, which dismisses all focused form control UI. For certain types of form
        controls, this prevents the user from using key pieces of functionality.

        To address this, disconnect the notion of first responder status from DOM element focus while the form control
        overlay is shown. Later, when the active input session ends, if the web content view was first responder before
        upon focusing the element, restore first responder status on the web view. This extra tweak is needed to ensure
        that certain UI affordances which require first responder status on the web view continue to work after
        interacting with a form control that changes the first responder.

        Resource Load Statistics: Make debug mode always partition prevalent resources
        https://bugs.webkit.org/show_bug.cgi?id=183468

        Reviewed by Brent Fulgham.

        After some testing we decided that a 30 second timeout in ITP debug mode just makes
        it confusing. We should instead always partition prevalent resources in debug mode
        to make it easy to understand. The partitioned state is what developers want to test
        anyway.

        Web Automation: script evaluations via WebDriver should have a user gesture indicator

        <rdar://problem/37959739>

        Reviewed by Andy Estes.

        APIs that normally require a user gesture should just work when using via WebDriver.
        To support cases where tests need to simulate user actions with JavaScript, use a
        fake user gesture, similar to how -[WKWebView evaluateJavaScript:] forces a user
        gesture when clients evaluate JavaScript in their web view.

        No new tests, this is covered by W3C tests that use the Fullscreen API.
        This API does nothing if there is no user gesture; with this patch, it just works.

        Notify the NetworkProcess when a session is servicing an automation client

        <rdar://problem/37835783>

        Reviewed by Brian Burg.

        Network loads servicing WebDriver are done through an ephemeral session. While this is great
        for protecting a developer's machine from sharing state with test runs, it has the unintended
        effect of blocking certain logging operations.

        We do not log content in ephemeral sessions to protect user privacy. However, ephemeral sessions
        generated by WebDriver should participate in logging so that proper testing (with logging) can
        be done.

        This patch signals the NetworkProcess when an ephemeral session (created for automation purposes)
        is created, so that it can allow logging.

        WebKitTestRunner is clearing caches for every test but there might still be some on-going cache activity due to a previous test.
        In that case, the activity might try to open the Caches object at the same time the files are deleted by the clearing task.
        If the new test is trying to open the same caches, it will also receive the same error, hence the console log message.

        To fix that issue, we clear the initialization pending callbacks when clearing the caches.
        This prevents the new test to receive the error since the new test should only start some cache activity after the cache clear task is done.
        Made refactoring to append the first callback into the list of pending callbacks.

        The notification about scrollbar preferences is never received by the WebContent process when there is no

        notifying the WebProcess about this by sending it a message. This message should also contain the preferred

        [Extra zoom mode] Implement additional SPI for adjusting viewport shrink-to-fit behavior
        https://bugs.webkit.org/show_bug.cgi?id=183100
        <rdar://problem/37840987>

        Reviewed by Tim Horton.

        Add new SPI hooks to provide finer control over certain aspects of the shrink-to-fit viewport heuristic.
        Currently, in certain cases of iPad multitasking, Safari allows shrinking content to fit by default. This means
        that even when "width=device-width" is used, if the contents of the page are too wide to fit within the
        viewport's width, we'll adjust the initial scale such that the viewport can fit all of the content.

        However, in certain viewport dimensions, this heuristic is insufficient to ensure that pages are laid out and
        displayed properly within the viewport. Namely, one could imagine that an element with a hard-coded width that
        is larger than the real viewport width would cause all other elements with dimensions relative to the body to be
        excessively shrunk down once shrink-to-fit is applied, so the page would still look broken even if the contents
        of the page all fit within the viewport.

        To mitigate this, we decouple the notions of minimum layout size from the size of the actual viewport (which we
        simply refer to as "view size"). This allows us to introduce a mechanism where we lay out the page at a given
        minimum layout size that is larger than the size of the view; later, when we determine the initial scale, we
        then apply shrink-to-fit scaling using the view size rather than the minimum layout size. This grants us the
        ability to lay out content as if our view were large, but still ensure that the contents of the page fit within
        the actual view.

        If we do not set it to nullptr, we end up storing the initialize

        This is difficult to test as we need the following conditions:

        Like other delegates functions in this file, it is possible for didReceiveChallenge to get called
        after _session has been nulled out. Other delegate functions already had early returns when
        _session is null. However, such early return was missing in didReceiveChallenge.

        This patch ends the early return to didReceiveChallenge so that we do not end up calling
        _session->downloadID(taskIdentifier) on a null _session.

        On macOS, the functions screenAvailableRect and screenRect is implemented using NSScreen, which is communicating
        with the WindowServer. To avoid this WindowServer communication from the WebContent process when calling

        process whenever there is a change in the display properties, and have the WebContent process cache these

        Adopt modern JSON::Value getters that return std::optional<float>. I have been trying
        to move the protocol over to this style wholesale, but it is probably easier to do

        Sometimes when running more than one session end-to-end with the same browser instance,
        UIProcess would crash under addMessageReceiver because another WebAutomationSession was still
        registered. This is hard to reproduce, but upon code inspection, the receiver management code
        is somewhat problematic because it only runs when the WebAutomationSession destructor runs.
        In some cases the client could retain two sessions and cause the first one to never remove itself
        as the message receiver.

        Instead of unregistering the session as a message receiver underneath the session's destructor,
        do this whenever a new session supplants an old session since there is only one active session at a time.

        [Extra zoom mode] Form control values are stale after dismissing and representing input view controllers
        https://bugs.webkit.org/show_bug.cgi?id=182877
        <rdar://problem/37604395>

        Reviewed by Tim Horton.

        Currently, when presenting an input view controller for a focused element, we populate the initial form control
        value using the WKContentView's assisted node information when it was last focused. However, if the user edits
        the value of a form control, dismisses to the form control view controller (while the element is still focused)
        and then begins editing the field again, the initial text will be the previous value of the input, since the
        AssistedNodeInformation isn't up to date.

        To fix this, we introduce a mechanism to update WKContentView's AssistedNodeInformation for the current assisted
        node. This overwrites _assistedNodeInformation with new information computed from the web process, as long as
        the assisted node before and after the request is made in the UI process has not changed. We accomplish this by
        adding an identifier to AssistedNodeInformation, which is monotonically incremented when an element is focused
        in the web process. The UI process may then use this identifier to determine whether AssistedNodeInformations
        are describing the same focused element.

        One interesting consideration here is that a normal AssistedNodeInformation update (propagated when focusing an
        element) may be deferred in the UI process until the next layer tree commit. In the absence of the assisted node
        identifier check, one could imagine a scenario in which the assisted node information in the UI process gets
        "updated" from a new value to an old value:

        1. The web process focuses an element and sends AssistedNodeInformation `A`.
        2. WKContentView calls -updateCurrentAssistedNodeInformation.
        3. The web process sends AssistedNodeInformation `B`.
        4. `A` is received in the UI process, but deferred.
        5. The UI process receives `B` and sets _assistedNodeInformation to `B`.
        6. The UI process calls -_startAssistingNode: and sets _assistedNodeInformation to `A`.

        This would mean that the _assistedNodeInformation is set to an earlier value, `A`, after being set to a later
        value, `B`. However, because the AssistedNodeInformation identifier in step (2) refers to the assisted node
        prior to step (1), the assisted node identifier in (5) would not match this identifier, and we would simply bail
        instead of overwriting assisted node information.

        We use this AssistedNodeInformation update mechanism after inserting text via input view controllers, and also
        after reentering edit mode from the focused form control view controller. This fixes two issues where changing
        the size of the focused element after editing it results in the focused form overlay highlighting a stale frame,
        and also when setting the initial text when reentering edit mode for a form control that is already focused.

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

        Add a new monotonically increasing identifier (per WebPage) which associates a AssistedNodeInformation with a
        focused element. In the event that the web process crashes and relaunches (thus resetting this identifier),
        AssistedNodeInformation state in the UI process is now also reset (see -cleanupInteraction), so we won't end up
        confusing AssistedNodeInformations computed by different WebPages between a web process crash.

        * UIProcess/WebPageProxy.h:

        assisted node information. Instead, just use the presence of m_deferredNodeAssistanceArguments.

        If the API to set a supported plug-in is called, WebKit enters a mode
        where it will block any plug-in that is not on the list.

        The list of supported plug-ins is stored in UIProcess and sent to WebProcess.
        This allows to compute the list of visible plug-ins according supported plugins.

        PluginInfoStore is storing the list of supported plugins and can
        answer whether a plug-in creation request is to be made unsupported or not.
        It also creates the structure sent to WebProcess for computing plugin visibility.

        Updated ArgumentCoders to accept modern HashSet decoders.

        (-[WKContentView presentViewControllerForAssistedNode:]):

        When focusing InputType::Time, present a time picker. Additionally, tweak the logic here to use the generic text
        input view controller as a fallback when the other input view controllers (number pads, select menus and time
        pickers thus far) are not relevant. This prevents us from completely being unable to edit form controls that are
        currently unsupported.

        Adjust this implementation to hide the focused form control "Go" button for selects and time inputs. This
        currently doesn't work for these form controls because it relies on implicit form submission; this should be
        fixed by future changes, after which we should revert this adjustment.

        Reviewed by Simon Fraser.

        Evernote implements the WKWebView's scroll view's delegate method
        viewForZoomingInScrollView: and returns nil. This results in
        WKScrollView's zoomScale always returning 1, no matter what the
        WKContentView's actual scale is. This will result in us never updating
        the WKContentView's scale to 1. When loading a page that has a few
        scale changes during load but ends up at scale 1, we get stuck at whatever
        intermediate scale immediately preceded settling on 1.

        Fix this by not forwarding viewForZoomingInScrollView: to the external
        WKScrollView delegate; we are in charge of the contents of the scroll
        view (including which view scrollView's zoomScale should track), and
        overriding viewForZoomingInScrollView: is only ever going to lead to
        a broken WebKit.

        do not do so. This means that fetch results might come in out of order with regards
        to the registration / service worker state updates. The test was flaky because an
        intercepted load would sometimes finish before the task to update the service worker
        state to "activated" was processed by the runloop. We address the issue by having

        Move the bit computation at page creation time.
        This allows computing the bit based on the web site data store and not only on the pool configuration.
        WebPage uses that bit to activate service worker registration matching for the whole process.

        In case there is a service worker process proxy created, the bit is set to true by default.

        Bit is computed by checking for database file presence.
        This information is cached in a map for efficiency reasons and cleared when a service worker process proxy is created.

        Somebody fixed a GC crash in r228001 by allowing RunLoop::current() to be called from a
        GC thread. However, this is still unnecessarily inefficient. Calling RunLoop::current()
        will construct RunLoops for background GC threads (WTF::AutomaticThreads). This patches
        updates the IPC code to call isMainThread() instead of RunLoop::isMain() in
        Connection::sendMessage(). This should mean the same thing since this code runs in
        WebKit2 and should be more efficient as it ends up simply calling pthread_main_np(),
        without constructing a RunLoop.

        It turns out that it is not always safe to look at the safe area insets of
        children from inside layoutSubviews, even after the call to super.

        Instead, make use of the fact that WKScrollView and WKWebView have identical
        coordinate spaces, and map WKWebView's safe area insets into the WKScrollView.
        It's safe to use the scroll view's affected-edges and contentScrollInset,
        because those aren't updated at the same outside-of-layout time that
        safe area insets are.

        We could alternatively move all calls to activeMinimumLayoutSize outside
        of layoutSubviews, but that seems like a larger and riskier change.

        All attempts to write a test have failed; this depends heavily on use of
        autolayout and the mechanism by which the system updates system-owned
        safe area insets during device rotation.

        - Only update partitioning and blocking table when needed. This is an optimization
          which pays off in less XPC with shorter timeouts.

        Enable library validation on the Web Content service
        Part 1 of https://bugs.webkit.org/show_bug.cgi?id=172365

        Reviewed by David Kilzer.

        This makes the Web Content process signed with the Library Validation flag in production
        builds. Because doing so would prevent engineering builds of Apple apps that use an
        injected bundle from working, this also adds a Development version of the service, which
        does not enforce Library Validation. The UI process chooses to use the Development service
        iff it would need to load an injected bundle that is not part of the OS.

        * Configurations/DebugRelease.xcconfig: Disable Library Validation in engineering builds.

        * Configurations/WebContentService.Development.xcconfig: Added. Like the normal service, but
          only installed when WebKit is installed in the OS, and uses a Development variant.

        * Configurations/WebContentService.xcconfig: For the Development variant, append
          ".Development" to the product name, which is also the service identifier. Enable Library
          Validation for the Normal variant of the service when WK_LIBRARY_VALIDATION_ENABLED allows
          it.

        Add a IPC::SendSyncOption indicating we should not process incoming IPC while waiting for the sync reply
        https://bugs.webkit.org/show_bug.cgi?id=182021
        <rdar://problem/21629943>

        Reviewed by Ryosuke Niwa.

        Add a new DoNotProcessIncomingMessagesWhenWaitingForSyncReply SendSyncOption that the caller can
        set when calling sendSync(). This indicates that the sendSync() should return only when we receive
        the response to our sync IPC message, and that we should not process ANY incoming IPC in the meantime.

        This patch also starts using this flag in 3 places where we know processing incoming IPC is an issue
        and is causing crashes.

        * Platform/IPC/Connection.cpp:
        (IPC::Connection::sendSyncMessage):
        When DoNotProcessIncomingMessagesWhenWaitingForSyncReply SendSyncOption is set, make sure
        we set the ShouldDispatchMessageWhenWaitingForSyncReply flag on the encoder. If we did not set this
        flag then it could cause deadlocks when the destination process is also waiting on a synchronous
        IPC from us. Normally, this flag already gets set for sync messages because sendSyncMessage() calls
        sendMessage() with DispatchMessageEvenWhenWaitingForSyncReply SyncOption. However, sendMessage()
        ignores the DispatchMessageEvenWhenWaitingForSyncReply flag if the
        m_onlySendMessagesAsDispatchWhenWaitingForSyncReplyWhenProcessingSuchAMessage flag is set on the
        connection. Note that this flag is set on the connection from the WebProcess to the UIProcess at
        the moment, which is why we saw deadlocks on the previous iteration of this patch.

        (IPC::Connection::waitForSyncReply):
        If DoNotProcessIncomingMessagesWhenWaitingForSyncReply SendSyncOption is set, do not
        process incoming IPC messages while waiting for our sync IPC reply.

        Reviewed by Carlos Garcia Campos.

        Let's fix this in two independent ways.

        First, use a GRefPtr to hold ownership of the WebKitWebViewBackend. This way, we don't need
        to change the order in which WebKitWebView destroys its priv struct members from what is
        used in WebKitGTK+, which can lead to odd bugs.

        Additionally, just for good measure, stop resetting the find client when disposing
        WebKitFindController. This is unnecessary because it will never be destroyed before the
        WebKitWebView.

        Reviewed by Joseph Pecoraro.

        What a mess.  We had a code path for asynchronous context menu generation and a different one for synchronous context menu generation.
        This makes it so there is just one.  At the API level we see if there is an asynchronous delegate to call, then synchronous.
        There is a subtle theoretical change in behaviour because m_page.contextMenuClient().showContextMenu is now called for the asynchronous
        case and it wasn't before, but the one C API client that uses this has nullptr as it's WKPageShowContextMenuCallback, so we won't break anything!

        m_isInitialized is true but m_storage is set to nullptr when calling writeRecord.
        The only case seems to be if:
        - We are doing persistent storage
        - We are traversing the storage to do the initialization. At that point m_storage is set to a correct value.
        - clearMemoryRepresentation is called, thus setting m_storage to nullptr and m_isInitialized to false.
        We fix this by making clearMemoryRepresentation a no-op if we are initializing the caches.
        clearMemoryRepresentation is about cleaning the in-memory information of the caches and the memory representation is empty at init time.
        Nullifying m_storage is a memory consumption optimization.

        iOS. Namely, startDrag should just forward the DragItem and drag image handle along to the appropriate views on

        There should be no change in behavior.

        REGRESSION(r219530): ResourceLoadStatisticsPersistentStorage should be read-only in ephemeral sessions
        https://bugs.webkit.org/show_bug.cgi?id=181136

        Reviewed by Chris Dumez.

        Some uses of WebKit involve running a UIProcess as an ephemeral session for the life of the process. In this
        case, we do not initialize the data path for the set of load statistics triggering an assertion.

        We actually intended ephemeral sessions to consume the existing resource load data (presumably captured during
        non-ephemeral browsing). This would be a read-only mode, where it would not add new entries to the load
        statistics, but would take advantage of existing observations. Currently that does not happen (for this type
        of WebKit embed), which forces each run as an ephemeral session to build up in-memory browsing data until it has
        enough observations to begin modifying loads.

        We need to set the ResourceLoadStatisticsPersistentStorage object to a "read only" mode in this case, so
        that it read (but does not write) from this database.

        There is a subtle theoretical change in behaviour because m_page.contextMenuClient().showContextMenu is now called for the asynchronous
        case and it wasn't before, but the one C API client that uses this has nullptr as it's WKPageShowContextMenuCallback, so we won't break anything!

        Storage Access API: Refactor to make naming accurate and explicit, simplify access table, and prepare for access removal for page
        https://bugs.webkit.org/show_bug.cgi?id=181357
        <rdar://problem/36331031>

        Reviewed by Alex Christensen.

        This change does the following:
        - Changes function and message names to reflect how this feature
          was eventually implemented, i.e. access per frame.
        - Makes it explicit that the UI process is only involved in
          granting storage access and not removing storage access.
          The latter is done directly by the web process.
        - Simplifies the network process' entry map since only needs to
          be able to give access to one domain in one frame at a time.
          Access goes away on frame navigation so there can only be one
          domain at a time per frame. Also, the map now uses pageIDs as

        of WKFrameRef, so we were just getting a WKObject when we wanted a _WKFrameHandle.

        The previous approach was problematic when _dispatchSetMinimumLayoutSize:
        was changed to not re-send identical updates, because if the client calls 
        _overrideLayoutParametersWithMinimumLayoutSize before the Web Content process
        is re-launched (after terminating), we would cache the size, attempt to send it,
        fail silently (because the process is not launched), and then in _didRelaunchProcess
        we would choose not to re-send (after the process is successfully relaunched)
        because we think we already sent the new value.

        Add isValid() checks to our message sends. Ideally send() would assert
        if the process is not alive to avoid problems like this, but it doesn't (yet).

        Get rid of WKWebView's _didRelaunchProcess, because it does nothing now.

        open and retrieveCaches now take a ClientOrigin instead of a String.
        Updated cache filesystem path computation to take both client origin and top origin.

        When clearing an origin, caches whose client origin or top origin matches the origin are cleared.
        Caches are added to the web site data of their client origin with their corresponding cache size.
        Caches are added to the web site data of their top origin with a size equal to 0.

        Updated memory representation dumping used for test to include both top and client origins.

        Storage Access API: Refactor XPC for access removal to go straight from the web process to the network process

        Reviewed by Alex Christensen.

        This change refactors how the web process tells the network process
        to remove storage access. Previously, this was done over the UI process
        just like requests for storage access. But since no further reasoning
        is needed, the message should go straight from the web process to the
        network process for performance reasons and to minimize the risk of a
        race.

        As a consequence, the XPC code for storage access removal in the UI
        process is deleted.

        [GTK] Add web process API to detect when form is submitted via JavaScript
        https://bugs.webkit.org/show_bug.cgi?id=173915

        Reviewed by Carlos Garcia Campos.

        Epiphany relies on the DOM submit event to detect when a form has been submitted. However,
        for historical reasons, the submit event is not emitted when a form is submitted by
        JavaScript. It is therefore not currently possible for a web browser to reliably detect form
        submission and not possible to implement a robust password storage feature. In order to
        avoid this problem, this patch adds a new WebKitWebPage signal, will-submit-form, that
        browsers can use in preference to a DOM event listener.

        Unfortunately, this signal is not available for WPE because it depends on the DOM API.

        There are two submission events, WEBKIT_FORM_SUBMISSION_WILL_SEND_DOM_EVENT and
        WEBKIT_FORM_SUBMISSION_WILL_COMPLETE. WEBKIT_FORM_SUBMISSION_WILL_SEND_DOM_EVENT
        occurs earlier than WEBKIT_FORM_SUBMISSION_WILL_COMPLETE and can be used to retrieve form
        values before websites receive the DOM submit event. This is useful as some websites like
        to delete form values right before a submit would normally happen in order to attempt to
        defeat browser password managers. There are two tricks to note: JavaScript can cancel form
        submission immediately after this event occurs (by returning false in an onsubmit handler),
        and, for historical reasons, this event will not occur at all when form submission is
        triggered by JavaScript. WEBKIT_FORM_SUBMISSION_WILL_COMPLETE occurs next, and is more
        straightforward: it is always emitted when a form is about to be submitted, when it is too
        late to cancel.

        The recommended way to reliably retrieve password form values would be to watch for both
        events, use the form value detected in WEBKIT_FORM_SUBMISSION_WILL_SEND_DOM_EVENT
        if that event is emitted, and use the value detected later in
        WEBKIT_FORM_SUBMISSION_WILL_COMPLETE otherwise.

        Since one of the signal arguments is an enum, we now have to run glib-mkenums for the web
        process API. And that has resulted in this patch also adding GType goo for
        WebKitConsoleMessageLevel and WebKitConsoleMessageSource that was previously missing. Any
        applications that for some unlikely reason want to use these enums in properties or signals
        will be happy.
