        Test: http/tests/swipe/swipe-back-with-outstanding-load-cancellation.html

        When swiping back from a page that is still loading, when the swipe commits,
        and we start navigating back to the previous page, the unfinished forward navigation
        is cancelled.

        This cancellation resulted in a "didFailLoadForMainFrame" making it to ViewGestureController,
        which took it as an indication that the navigation *it* was interested in (the back navigation)
        had failed, and immediately removed the snapshot.

        Instead of listening to any random navigation's load notifications, keep track of the navigation
        started by goToBackForwardItem, and only listen to notifications from it, ignoring the others.

        This requires a bunch of plumbing to get the navigation from WebPageProxy to ViewGestureController,
        but is otherwise fairly trivial.

        Regression(r259242) WebKit no longer does client navigations at foreground priority for extensions

        Reviewed by Alex Christensen.

        r259242 tried to address a ASSERT(window) debug assertion hit in applicationType()
        by only calling applicationType() when the window is non-null and assuming the
        process is an application when the window is null. However, this is not correct
        for extensions. The first thing isApplicationVisible() does is call 
         _UIApplicationIsExtension() to determine if we are an extension. It does not need
        the window to make this determination. As a result, I have reverted r259242 and
        simply dropped the ASSERT(window) assertion in isApplicationVisible() instead.

        This fixes the regression tracked by <rdar://problem/63300428> by reverting the
        change that caused it (r259242) and drops the assertion that was hit before r259242.

        Crash under IPC::isValidMessageName()

        Reviewed by Geoffrey Garen.

        This is a speculative fix for the crashes tracked by <rdar://problem/64773416>.
        The suspicion is that the compiler optimizes the code for IPC::isValidMessageName()
        because its parameter is of type MessageName. It may therefore assume the parameter
        is a valid MessageName enum value, which is ironic because the purpose of this
        function is to check whether or not the enum value is valid.

        To address the issue, I got rid of the #ifdefs in MessageName enum so that the
        enum values have an underlying value in the range [0, MessageName::Last]. I then
        updated the isValidEnum template specialization to verify that the input integer
        is indeed in the range [0, MessageName::Last] before casting it to a MessageName
        and calling IPC::isValidMessageName().

        [macOS] Connections to the preference daemon are established before entering the sandbox
        https://bugs.webkit.org/show_bug.cgi?id=213379

        Reviewed by Darin Adler.

        On macOS, connections to the preference daemon are established before entering the sandbox. These connections also persist
        after entering the sandbox and denying access to the preference daemon. There should not be attempts to connect to the
        preference daemon before entering the sandbox, since these attempts will not be stopped by the sandbox. This patch moves
        code that connects to the preference daemon to be executed after the sandbox has been entered. That includes code to
        prevent connections to the Dock and code to initialize WebKit logging. Also, instead of calling [NSBundle bundleForClass:],
        call [NSBundle bundleWithIdentifier:], since calling [NSBundle bundleForClass:] will connect to the preference daemon.
        Finally, allow the syscall SYS_gethostuuid, since that is needed by CoreFoundation when there is no access to the
        preference daemon.

        No new tests. This should be covered by existing tests. It would be nice to have a test to make sure that there are no
        connections to the preference daemon just before entering the sandbox, but I am not aware of how to implement this.

        Reviewed by Tim Horton.

        This test first taps an input field to focus it, taps a button below the input field to focus the button and
        dismiss the keyboard, and finally long presses to select a word below the button. On recent iOS 14 builds, this
        test occasionally fails due to recent changes in UIKit that may cause the callout bar appearance callback to
        fire after focusing the input field. If this happens, we end up showing the callout bar with a single option to
        "Select All" (despite the field being empty), and the subsequent tap that's intended to hit the button instead
        hit-tests to this callout bar item. The tests subsequently times out waiting for the keyboard to dismiss, which
        never happens because the input field remains focused.

        Showing the "Select All" callout bar option in empty text fields is inconsistent with the rest of the platform
        (iOS), and appears to have been unintentionally introduced in iOS 12 by <https://trac.webkit.org/r231726>. While
        it's still unknown which exact system changes caused this test to begin timing out, we can at least fix it by
        addressing this existing regression in behavior.

        Use std::min and std::max when the result needs to be copied instead of doing the comparison

        The scroll position for an overflow:scroll element with scroll-snap could jump around
        during scrolling, if layout triggered a call to ScrollableArea::updateScrollSnapState().
        The crux of the issue is that isScrollSnapInProgress() returned false for overflow:scrollers
        which are scrolling asynchronously.

        Fix by extending the existing ScrollingTree::isScrollSnapInProgress() to track all scrolling
        nodes by storing a HashSet<ScrollingNodeID> rather than just a flag for the main frame.

        RenderLayer::isScrollSnapInProgress() then consults the ScrollingCoordinator, which consults
        the scrolling tree for this state.

        Add the ability to test via internals.isScrollSnapInProgress().

        [iOS] Open element actions sometimes result in a hover instead of a click
        https://bugs.webkit.org/show_bug.cgi?id=213530
        <rdar://problem/64176707>

        Reviewed by Darin Adler.

        _WKElementAction implements a standard action handler for _WKElementActionTypeOpen that
        attempts a synthetic click at the interaction location, expecting this click to start a
        navigation to the interaction node's target URL. Synthetic clicks are subject to content
        change observing, however, and if ContentChangeObserver detects a meaningful visible change
        after dispatching a mousemove event at the interaction location then WebPage will refrain
        from dispatching the mousedown and mouseup events that would have started a navigation.

        While this behavior is necessary to support hover menus, it doesn't make sense when the user
        is interacting with a context menu. Since the system might display a preview of the target
        URL found at the interaction location, users expect the "Open" action to navigate to that
        same URL rather than merely display a hover menu.

        This change opts synthetic clicks from the open action out of content change observing by
        ensuring that an interaction is started when handling _WKElementActionTypeOpen (like we do
        for "Copy" and "Save Image"), then checking if WebPage::m_interactionNode matches the node
        found in WebPage::attemptSyntheticClick. If it does, WebPage now bypasses content change
        observing and completes a synthetic click.

        Reading the experimental feature wasn't working on iOS because the user defaults prefix is different.
        Also, only resolve and create the directory if it is enabled.  This should help with startup time, which
        has to wait for all directories to be resolved and created.  See rdar://problem/64263228 which this should help with.
        We also respect the system default unless explicitly turned on, which should make it easier for CFNetwork to change things.

        I added an API test that verifies that the default alt-svc storage directory is not created when we don't want it to be.

        REGRESSION (r244633): Mail flashes when copying text in an email
        https://bugs.webkit.org/show_bug.cgi?id=213529
        <rdar://problem/55025522>

        Reviewed by Tim Horton.

        When copying a text selection in Mail conversation view, Mail uses injected bundle hooks to supply additional
        metadata before writing to the pasteboard. Grabbing this data involves temporarily expanding any collapsed
        blockquotes that appear in the mail message, before re-collapsing them after we finish gathering data to be
        written to the pasteboard.

        Prior to r244633, the size of the document while expanding collapsed content would not be propagated to the
        WKWebView, since intrinsic content size changes were batched and sent ahead of the next drawing area flush.
        After r244633, however, updates are now sent every time the layout size changes. This was done to ensure that
        the intrinsic content size was always up to date before sending the first layout milestone to the UI process.

        To preserve the intent of r244633 (with respect to the first layout milestone) as well as intrinsic content size
        behavior prior to r244633 after performing layout, we reintroduce the mechanism for batching intrinsic size
        updates until the next flush, but keep the out-of-band mechanism for immediately sending an up-to-date intrinsic

        [Apple Pay] WebPaymentCoordinatorProxy can be destroyed without dismissing its authorization presenter
        https://bugs.webkit.org/show_bug.cgi?id=213423
        <rdar://problem/60416221>

        Reviewed by Youenn Fablet.

        When a website completes a payment session, WebPaymentCoordinatorProxy would set its m_state
        to Idle by calling didReachFinalState, but would wait to call hidePaymentUI until the
        payment authorization presenter calls its presenterDidFinish callback. This allows the
        presenter to display a final message to the user before dismissing. As a catch-all,
        ~WebPaymentCoordinatorProxy would call hidePaymentUI, but only if m_state wasn't Idle. If a
        WebPaymentCoordinatorProxy was destroyed after a website completed a payment session but
        before the presenter called presenterDidFinish, hidePaymentUI would never be called.

        This patch addresses this by simplifying the logic for completing or canceling a payment
        session. It's based on the following observations:

        1. With the exception of the case described above, every caller of didReachFinalState would
           also call hidePaymentUI immediately beforehand. That means that we can move the calls to
           hidePaymentUI inside didReachFinalState. For the completePaymentSession case, rather than
           call didReachFinalState without dismissing the UI, we enter a new Completing state, then
           call didReachFinalState either in ~WebPaymentCoordinatorProxy or presenterDidFinish.

        2. didCancelPaymentSession is really a special case of didReachFinalState that also sends
           the DidCancelPaymentSession message to cancel active sessions in the web process. We can
           teach didReachFinalState to send this message when necessary and remove
           didCancelPaymentSession.

        3. PaymentAuthorizationPresenter stored a "did reach final state" boolean on payment
           completion and passed this value back to the client in the presenterDidFinish callback.
           WebPaymentCoordinatorProxy used this to determine whether to cancel an active session by
           calling didCancelPaymentSession or clean up a completed session by calling hidePaymentUI.
           With the addition of the Completing state and the merging of didCancelPaymentSession and
           hidePaymentUI into didReachFinalState, we can get rid of this final state tracking in
           PaymentAuthorizationPresenter and unconditionally call didReachFinalState in the
           presenterDidFinish callback.

        No new tests possible. A manual test case is described in <rdar://problem/60416221>.

        [macOS] Connections to the preference daemon are established before entering the sandbox
        https://bugs.webkit.org/show_bug.cgi?id=213379

        Reviewed by Darin Adler.

        On macOS, connections to the preference daemon are established before entering the sandbox. These connections also persist
        after entering the sandbox and denying access to the preference daemon. There should not be attempts to connect to the
        preference daemon before entering the sandbox, since these attempts will not be stopped by the sandbox. This patch moves
        code that connects to the preference daemon to be executed after the sandbox has been entered. That includes code to
        prevent connections to the Dock and code to initialize WebKit logging. Also, instead of calling [NSBundle bundleForClass:],
        call [NSBundle bundleWithIdentifier:], since calling [NSBundle bundleForClass:] will connect to the preference daemon.
        Finally, allow the syscall SYS_gethostuuid, since that is needed by CoreFoundation when there is no access to the
        preference daemon.

        No new tests. This should be covered by existing tests. It would be nice to have a test to make sure that there are no
        connections to the preference daemon just before entering the sandbox, but I am not aware of how to implement this.

        https://bugs.webkit.org/show_bug.cgi?id=213381
        <rdar://problem/64533003>

        Reviewed by Darin Adler.

        RemoteInspector::singleton() is expensive according to traces. It was called in WebProcessPool::initializeNewWebProcess()
        which happens on MobileSafari launch because we prewarm a WebProcess. However, there is no reason to initialize remote
        Web Inspector at this point. Per associated comment, Remote Web Inspector needs to be initialized once there is a
        sub process hosting one of our Web View. As a result, I moved the initialization call to WebPageProxy::initializeWebPage()
        which is when we actually send the IPC to the WebProcess to create the WebPage that is backing the UI-side WebView.

        [Mac Catalyst] Color inputs and selects fail to display popovers when clicked
        https://bugs.webkit.org/show_bug.cgi?id=213157
        <rdar://problem/64004135>

        Reviewed by Tim Horton.

        In Mac Catalyst, presenting popovers using `UIPopoverController` causes the first responder to change. This
        means that the WKContentView will resign first responder, which in turn causes the currently presented popover
        to be dismissed. This means that popovers for color inputs and select elements will be dismissed immediately
        after presentation.

        To mitigate this, adapt the approach taken in r259840 to `WKColorPopover` and `WKSelectPopover` by teaching the
        base class (`WKRotatingPopover`) to temporarily preserve the focused element in light of first responder changes
        while presenting a popover on Mac Catalyst.

        [iPadOS] Focusing selects and color inputs should not bring up the software keyboard
        https://bugs.webkit.org/show_bug.cgi?id=213149
        <rdar://problem/64312450>

        Reviewed by Darin Adler.

        After <trac.webkit.org/r261658>, we now opt into bringing up the software keyboard when focusing color inputs
        and select elements. This is due to the changes in `-_shouldShowAutomaticKeyboardUIIgnoringInputMode`, which
        were intended to make us return `NO` for date and time inputs, but also unintentionally makes us return `YES`
        on iPadOS.

        This patch fixes the bug by returning `!WebKit::currentUserInterfaceIdiomIsPad()` instead, and additionally
        preserves the existing behavior of now showing a color picker for `<input type="color" readonly>` on iPhone.

        [iOS] Preferences are not being observed if the process pool is being created after activation

        Reviewed by Brent Fulgham.

        If the app is creating the Web process pool after being activated, preferences will not be observed until the app is being backgrounded
        and then foregrounded again, since the preference observer is initialized when handling the app activation notification.

        No new tests, since an API test would make sense in this case, but API tests aren't run on iOS.

        [IPC] Add WTF::EnumTraits<> for every enum type used in IPC
        <https://webkit.org/b/213093>

        Reviewed by Darin Adler.

        Summary:
        - Change underlying type of enum class to `bool` when there are
          only two values.  In some cases, reorder the two values so the
          mapping to 0 and 1 makes more sense.  Converting every enum to
          an enum class is not a goal of this patch, so some two-value
          enums stil have WTF::EnumTraits<> defined as noted below.
        - Add WTF::EnumTraits<> for the remaining enum types that are
          used by IPC::Encoder::encodeEnum() and
          IPC::Decoder::decodeEnum() so that WTF::isValidEnum<>() checks
          may be added next.

        [iOS] editing/pasteboard/dom-paste tests consistently time out
        https://bugs.webkit.org/show_bug.cgi?id=213061
        <rdar://problem/64211161>

        Reviewed by Darin Adler.

        On recent versions of iOS, system changes have moved the timing of the call to
        `-requestAutocorrectionContextWithCompletionHandler:` when focusing an editable element. This results in a
        consistently reproducible deadlock between the UI process and web process if a page tries to request
        programmatic clipboard access during the click event (importantly, in the same runloop as element focus).

        What ends up happening is that the autocorrection context is requested by the UI process shortly after the
        (unbounded) sync IPC message for the DOM paste arrives, so we end up waiting forever for the sync-IPC-blocked
        web process to respond. Normally this just results in a 1 second hang, and the DOM paste proceeds as normal.
        However these layout tests purposefully opt out of sync IPC timeouts (precisely so that we can catch bugs like
        this). See below for more details.

        * UIProcess/ios/WKContentViewInteraction.h:

        Keep track of the most recent autocorrection context that arrived in the UI process.

        * UIProcess/ios/WKContentViewInteraction.mm:
        (-[WKContentView cleanUpInteraction]):

        Clear out the autocorrection context, in case the web process crashes.

        (-[WKContentView requestAutocorrectionContextWithCompletionHandler:]):

        If the autocorrection context is requested while handling a DOM paste, we know that the latest autocorrection
        context must be up to date, since the autocorrection context is computed and sent immediately before a DOM paste
        request. Use this to immediately invoke the completion handler, without any sync IPC back to the web process.

        On Mac Catalyst, we attempt to take a sandbox extension for `com.apple.frontboard.systemappservices` when
        uploading a file; this service does not exist in Catalyst, and we consequently encounter a release assertion
        under `WebPage::didChooseFilesForOpenPanelWithDisplayStringAndIcon`.

        Fix this by introducing `HAVE(FRONTBOARD_SYSTEM_APP_SERVICES)`, and using it to guard codepaths that attempt to
        grab a mach extension to this service. (As a followup, we should consider adopting this in other places that
        currently reference `com.apple.frontboard.systemappservices`).

        [Cocoa] CFPrefs synchronization does not always work for global preference changes
        https://bugs.webkit.org/show_bug.cgi?id=212783

        Reviewed by Tim Horton.

        In CFPrefs direct mode, synchronization of global preference changes from the UI process to the WebContent process does not always work.
        This is caused by the KVO notification being sent to all or some of the NSUserDefault objects, which leads us to believe a non-global
        preference was changed. Since a global preference change always leads to some NSUserDefaults object receiving the notification, we can
        work around this by checking if the preference being changed really belongs to the domain of the NSUserDefaults object, or if it is a
        global preference. Also, stop creating NSUserDefaults object for the global domain, since this is an error according to the docs.

        [iOS] Hit-testing on icloud.com is offset after closing a tab
        https://bugs.webkit.org/show_bug.cgi?id=212890
        <rdar://problem/58775297>

        Reviewed by Simon Fraser.

        After tapping to create a new tab on the icloud.com settings page (with no other tabs open) and then closing the
        new tab, all hit-testing on the page is offset by -33px until the page is reloaded. This bug appears to be a
        corner case triggered by a combination of the following three changes:

        - <https://trac.webkit.org/r170463>
        - <https://trac.webkit.org/r245006>
        - <rdar://problem/53660458> (which is an iOS-specific Safari change)

        We start on icloud.com's settings page. When closing the newly created tab, Safari hides the tab bar, causing
        both the top content inset and top obscured inset to decrease by 33 points. When applying the top content inset
        change, Safari (after <rdar://problem/53660458>) temporarily sets `_automaticContentOffsetAdjustmentEnabled` on
        `WKScrollView` to `NO`, which means that the scroll view doesn't automatically adjust its content offset to -70;
        instead, it remains at -103 (the content offset when the tab bar is shown).

        Because of this, during the next remote layer tree commit where the content size changes,
        `-_setContentSizePreservingContentOffsetDuringRubberband:` will believe that we're currently rubber-banding by
        33px, and therefore try to adjust the content offset of the scroll view to be -103 instead of allowing it to be
        adjusted back to -70 (see r170463 and `-_restoreContentOffsetWithRubberbandAmount:`).

        This results in the scroll position on the page (`document.scrollingElement.scrollTop`) reporting -33, even
        though the top of the page is flush with the bottom of Safari's browser chrome. Finally, because `WKScrollView`
        is made unscrollable due to `overflow: hidden;` (r245006), we end up permanently stuck in this state until the
        next page load, rather than the next remote layer tree commit that causes any scrolling.

        To fix this, add an additional restriction on the rubberbanding offset restoration code in
        `-_setContentSizePreservingContentOffsetDuringRubberband:`, such that we only try to preserve the current
        rubberbanded offset if we're actually rubberbanding (that is, dragging or bouncing against the edge of the
        scroll view). Note that when rubberbanding against the top of the scroll view on iPad using a trackpad, the
        `-isDragging` property is also true, which matches behavior when panning via touch.

        Also, split out the `CGSizeEqualToSize(currentContentSize, contentSize)` case into a separate early return that
        skips the call to `-setContentSize:` altogether.

        Web Inspector: unify the naming scheme for agents used by instrumentation
        https://bugs.webkit.org/show_bug.cgi?id=212859

        Reviewed by Timothy Hatcher.

        Inspector agents fall into one of three categories:
         - "persistent" when Web Inspector is connected
         - "enabled" when that agent is `enable`d, such as if the corresponding tab is visible
         - "tracking" when that agent is part of a timeline recording.

        The only exception to this is the Console agent, as that exists regardless of whether Web
        Inspector is connected as it needs to preserve messages logged before Web Inspector connects.

        Also remove the "Inspector" prefix from getter/setter methods as it adds confusion if that
        agent also has subclasses (e.g. `InspectorRuntimeAgent` and `PageRuntimeAgent`).

        The WebContent process should never write preferences. Adopt read-only mode for preferences.
        This will fix some sandbox violations when the UI process is notifying the WebContent process
        about preference changes. When notified, the WebContent process will use the preferences API
        to write those preferences in-process, but there should be no attempt at writing these new
        values to disk, which this patch will ensure.

        No new tests, since this is fixing a benign sandbox violation.

        https://bugs.webkit.org/show_bug.cgi?id=212619

        Reviewed by Alex Christensen.

        WKProcessAssertionBackgroundTaskManager was incorrectly ignoring process assertion expiration notifications
        for daemons, because it was relying on visibility to make decisions. For daemons (or ViewServices), we would
        not get application visibility notifications and would therefore always assume the app is visible.
        As a result, _handleBackgroundTaskExpiration would think it received an outdated expiration notification for
        a visible app and would simply re-take the assertion right away.

        To address the issue, we now rely on a RunningBoard API that lets us know if the suspension timer has been
        started or not (and how much remains on the timer). If the suspension timer is not active when get receive
        the expiration notification, we know it is an outdated notification and we ignore it (release and re-take
        assertion right away). This can happen if we did not have time to process the expiration notification before
        suspended and thus only get it upon resuming. It can also happen if the user re-activates the app right after
        the expiration notice has been sent.

        Reviewed by Per Arne Vollan.

        Two issues with the "CFPrefs Direct Mode" mechanism caused dynamic changes to the
        user accent color preference to not be respected anymore:

        - the default change, when synchronized to the Web Content process, was
        written into the wrong domain, because of bug 212627.

        - AppKit caches the resolved accent color; the cache is invalidated when the
        a CoreUI notification is posted. Since we synchronize preferences ourselves,
        the ordering of the default change and notification are no longer guaranteed,
        so AppKit sometimes reads and re-caches the old accent color.

        [WKProcessAssertionBackgroundTaskManager _handleBackgroundTaskExpiration] may get called on a background thread
        by RunningBoard. When this happened it would check the _applicationIsBackgrounded flag on a background thread,
        which was not safe, it would also call _releaseBackgroundTask on the background thread which definitely was not
        safe and could lead to crashes such as the one in the radar.

        To address the issue, we now call callOnMainRunLoopAndWait() as soon as _handleBackgroundTaskExpiration gets
        called and run the whole implementation on the main thread. Previously, we were already doing a dispatch_sync()

        Prepare for async scrolling in passive wheel event handler regions

        Reviewed by Tim Horton.

        Clarify the processing for wheel events by adding OptionSet<WheelEventProcessingSteps>,
        which will, in future, allow us to describe the processing for an event in the passive
        event handler region which does scrolling on the scrolling thread, and is then sent
        to the main thread for DOM event dispatch.
        
        Removed ScrollingEventResult, which conflated "handled" with "send to another thread".
        The thread sending behavior is now encoded in the WheelEventProcessingSteps, and we can just
        use a bool for handled.
        
        Scrolling tree and node handleWheelEvent() functions return a WheelEventHandlingResult, which
        is a tuple of OptionSet<WheelEventProcessingSteps> and 'handled', allowing for a node with
        background-attachment:fixed to add the "send to main thread" processing step.

        Simplify EventDispatcher wheel event dispatch
        https://bugs.webkit.org/show_bug.cgi?id=212490

        Reviewed by Tim Horton.

        The various cross-thread bounces and completion lambdas in EventDispatcher::wheelEvent()
        and ScrollingTree code made the logic very hard to follow.

        Moving the ScrollingThread::dispatch() into EventHandler code simplifies things a little,
        and allows for removal of the hokey "try to handle" ScrollingTree function, as well
        as the clunky completion function.

        Now, EventHandler call shouldHandleWheelEventSynchronously(), then does the
        ScrollingThread::dispatch() which allows the lambda to easily call back into
        EventHandler for the main thread dispatch.

        RemoteScrollingCoordinatorProxy/RemoteLayerTree code is unused at present, and

        we accidentally create the GVariant using data we don't own. (Here, the data is owned by the
        Decoder itself in its internal m_buffer.) Anyway, this is fixable by manually copying and
        freeing it with the GDestroyNotify parameter, but it's easier to switch to
        g_variant_new_from_bytes() because GBytes takes ownership when constructed.

        The "Copy Custom WebContent Resources to Framework Private Headers"
        build phase in the WebContent target of the WebKit project doesn't
        advertise the files that it produces. This has consequences on later
        build phases that consume those files. In particular, XCBuild is left
        not knowing where those files are coming from, and it fails saying
        that those files don't exist. Fix this by adding the output files to
        the "output files" section of the custom build phase.

        Reviewed by Darin Adler.

        Switch from the "legacy" Xcode build system to the "new" build system
        (also known as "XCBuild"). Switching to the new system speeds up
        builds by a small percentage, better validates projects for
        build-related issues (such as dependency cycles), lets WebKit benefit
        from future improvements in XCBuild such as those coming from the
        underlying llbuild open source project, and prepares us for any other
        tools built for this new ecosystem.

        Specific changes:

        - Remove Xcode project and workspace settings that selected the Build
          system, allowing the default to take hold (which is currently the
          New build system).
        - Updated webkitdirs.pm with a terser check for Xcode version.
        - Update build-webkit and Makefile.shared to be explicit when using
          the old build system (no longer treat it as a default or fall-back
          configuration).
        - Update various xcconfig files similarly to treat the default as
          using the new build system.
        - Update various post-processing build steps to check for Xcode 11.4
          and to no longer treat the default as using the old build system.

        Provides Swift-only overlay methods for our NS_REFINED_FOR_SWIFT API.
        The overlay does not provide different API than its Objective-C counterparts,
        so overlay testing focuses on ensuring that the overlay produces the
        expected interface, and provides the expected mappings to and from ObjC.

        The overlay is defined in a separate Xcode project (from WebKit) by
        recommendation from the Swift team. Due to build system constraints this
        project cannot be a sibbling of WebKit.xcodeproj, and must live in a
        subdirectory. However, because it generally acts as part of the WebKit
        framework, it still uses the same Version.xcconfig and source file

        [IPC] Add support for specifying `Async WantsConnection` in message files
        https://bugs.webkit.org/show_bug.cgi?id=212276

        Reviewed by Alex Christensen.

        Augments the IPC message receiver generation script to allow for "Async WantsConnection" in `.message.in` files.
        Currently, specifying this in a message causes the `connection` argument to be passed twice when handling the
        IPC message. This is because normal async IPC messages without replies normally don't have the `IPC::Connection`
        argument, and use the overloaded `handleMessage(Connection& connection, ...)` version of `handleMessage` when
        `WantsConnection` is specified.

        However, in the `Async` reply case, we already pass in the `IPC::Connection`. Instead of overloading the method
        signature, we introduce a different method instead, named `handleMessageAsyncWantsConnection`, which forwards
        the given `IPC::Connection` along to the member function.

        * Platform/IPC/HandleMessage.h:
        (IPC::handleMessageAsyncWantsConnection):

        Add another variant of the message receiver template, for the case where the message receiver wants a connection.

        Storage Access API: Allow configurable storage access scope
        https://bugs.webkit.org/show_bug.cgi?id=212114
        <rdar://problem/63423063>

        Reviewed by Alex Christensen.

        The scope of storage access as per-frame or per-page was discussed in the
        standards process here: https://github.com/privacycg/storage-access/issues/3

        The decision was to have per-page storage access by default. Recent feedback
        from Google and conversation with Mozilla suggest that we might want to
        support the caller choosing the scope.

        This patch adds support for different scope configurations while keeping the
        existing default as per-frame. A later patch will switch the default and add
        test cases for per-page scope.

        Most of the changes is piping through the new enum
        WebCore::StorageAccessScope from the call side to encode per-frame and
        per-page access, and piping through the new struct
        WebCore::RequestStorageAccessResult on the return side which carries full
        information about the storage access request result.

        WebKit generates new compiled sandbox profiles whenever sandbox profiles are updated or
        whenever webkit directories change (which is super common for WebKitTestRunner). Previous
        compiled sandbox profiles do not get deleted and therefore may accumulate.

        To address the issue, we now save compiled sandbox profiles under _CS_DARWIN_USER_TEMP_DIR
        instead of _CS_DARWIN_USER_CACHE_DIR. The system takes care of deleting the files under
        _CS_DARWIN_USER_TEMP_DIR upon reboot or if they have not been accessed for 3 days.

        Reviewed by Carlos Garcia Campos.

        This patch brings initial GAMEPAD API support to the gtk port. We use libmanette,
        a simple GObject game controller library to handle gamepad connection and input.

        Patch to support Operating Dates in the ResourceLoadStatisticsDatabaseStore.
        Moves functions out of ResourceLoadStatisticsStore now that each store
        needs its own implementation.

        Adds a new function for testing which inserts an expired statistic
        and makes sure the proper behavior occurs depending on additional

        On Mac, WebKit has been using the +[NSMenuItem standardShareMenuItemForItems:] SPI to create
        the "Share" context submenu and menu item. This call performs synchronous IPC and can result
        in UI process spins.

        Where available, switch to using the asynchronous
        -[NSSharingServicePicker getMenuWithCompletion:] SPI instead. This method only creates the
        submenu, not the menu item, so when using this new method we must create the "Share" menu

        Reviewed by Tim Horton.

        After the changes in r258919, WKContentView's text input traits report that we're in a single line input, even
        when there is no editable focused element. This prevents UIKit from allowing WebKit to handle the `CTRL + M`
        key command, which is interpreted at the system level as inserting a line break in a multi-line editable area.

        It seems odd to consider ourselves in a single line input when there isn't even an editable element focused
        element; for now, we can fix these failing tests by just going with the default value for the text input traits'
        `setIsSingleLineDocument` property, but not explicitly setting it to either `NO` or `YES` when no element is
        focused.

        [macOS] Drag and drop within a contenteditable area duplicates attachment-backed images
        https://bugs.webkit.org/show_bug.cgi?id=212075
        <rdar://problem/62434146>

        Reviewed by Andy Estes.

        When the attachment API is enabled, starting a drag on an attachment-element-backed image within a
        contenteditable area sometimes causes the ranged selection to collapse. This is because `WebViewImpl::startDrag`
        has a separate codepath for starting a drag with attachment metadata that doesn't invoke `NSView`'s deprecated
        `-dragImage:at:offset:event:pasteboar:source:slideBack:` method, but instead uses
        `-beginDraggingSessionWithItems:event:source:`. While the former spins the runloop until the end of the drag
        session, the latter does not and returns immediately after beginning the drag. As a result,
        `WebPageProxy::didStartDrag()` is actually invoked after the drag ends when dragging non-attachment content,
        whereas `WebPageProxy::didStartDrag()` is invoked immediately after beginning the drag when starting a drag in
        an attachment or attachment-backed image element.

        This call to `didStartDrag()` is used to inform the web process that dragging has begun, and sets the
        `m_isStartingDrag` flag on `WebPage` to false. As a result, `m_isStartingDrag` is true over the course of the
        drag session when dragging non-attachment elements, but it's only true while starting the drag when dragging
        attachments. This flag is consulted in `WebPage::mouseEvent()` to determine whether we should avoid handling the
        incoming mouse event when beginning a drag. This prevents these incoming mouse events from triggering selection
        changes while dragging (for more details, refer to <http://trac.webkit.org/r176687>).

        Now, if we combine this with the fact that mouse events can be queued up in the UI process (refer to
        <https://trac.webkit.org/r230817>), it's possible to end up handling these queued mouse events in the web
        process after `m_isStartingDrag` has been set back to false when dragging an attachment. This doesn't happen
        when dragging non-attachment content, since we don't call `didStartDrag()` until the drag has already ended, so
        any queued mouse events are sent to the web process and immediately dropped on the floor since
        `m_isStartingDrag` is true.

        To address this, we make a couple of minor adjustments:

        1.  Invoke `didStartDrag()` right before calling into `-dragImage:at:offset:event:pasteboar:source:slideBack:`,
            so that we don't wait until the drag ends to set `m_isStartingDrag` to false. This makes the behavior of
            both codepaths for starting a drag (attachment and non-attachment) consistent, and also makes it consistent
            with iOS.

        2.  In `didStartDrag()`, discard any queued mouse events to prevent them from being handled by the page (e.g.
            causing the selection to change immediately after starting the drag). We already have identical logic to do
            this when showing a context menu, so we can factor this out into a private `WebPageProxy` helper and call it
            from both places.

        Fixes a long-standing bug in WKMultipleSelectPicker. Prior to this patch, we rely on the delegate method
        `-pickerView:row:column:checked:` to be called twice whenever an item is selected: one time for the item that is
        no longer checked, and another for the newly checked item. This method is responsible for updating the cached
        `FocusedElementInformation` that determines the data model for the select menu, with the expectation that the
        unchecked item would be updated to have `isSelected = false;`, and the new checked item would have `isSelected`
        `= true;`.

        However, `-pickerView:row:column:checked:` is only called for visible item cells. This means that if the user
        checks an item, scrolls the select menu items down so that the checked item is offscreen, and then checks a
        different item, we only get notified that the new item is checked, and as a result, fail to uncheck the previous
        item.

        To address this, tweak our logic for handling a single select so that when an item is checked, we additionally
        update the previously checked item to not be selected. Also, fix what seems to be a bug in the logic for
        updating `_singleSelectionIndex`, which is currently updated even when the item is unchecked. It seems to work
        out at the moment, because `-pickerView:row:column:checked:` seems to be called with `checked := YES` after the
        previous item was unchecked (assuming that it was visible).

        The changes in r242551 refactored synchronous autocorrection context request logic such that it uses
        `waitForAndDispatchImmediately` instead of `sendSync`, in order to make it interruptible by unbounded sync IPC
        sent from the web process. If the UI process receives sync IPC, it will immediately cancel the autocorrection
        context request (returning an empty context), before proceeding to handle the incoming sync IPC.

        In a more recent version of iOS, other changes around spellchecking have caused the synchronous message
        `WebPageProxy::checkTextOfParagraph` to be sent from the web process in such a way that it now frequently
        coincides with the synchronous autocorrection context request being sent from the UI process. The result is that
        we now frequently end up cancelling autocorrection requests early by responding with empty contexts. This
        manifests in the keyboard sometimes losing information about its autocapitalization context and believing that
        it is in an empty text field, which reverts to default autocorrection suggestions and autocapitalizes the
        software keyboard.

        To fix this, instead of using the `InterruptWaitingIfSyncMessageArrives` option when waiting for the IPC
        response, add and use a new flag that allows us to process an incoming sync IPC message if we're waiting for
        the sync message response. We use this new IPC flag when waiting synchronously for HandleAutocorrectionContext.

        - Templatize Encoder::encode(), Decoder::decode() and

        New Test: IOSMouseSupport.WebsiteMouseEventPolicies

        Plumb a "mouse event policy" WKWebpagePreference, which has two values:

        - Default, which means that WebKit decides whether or not indirect
        pointing devices send mouse or touch events.

        - SynthesizeTouchEvents, which ensures that WebKit will always send
        touch events from indirect pointing devices.
        This value is only available on platforms that implement touch events.

        We use the WKWebpagePreferences mechanism in order to make it easy to
        implement it as a "per-site" quirk, but unlike most WKWebpagePreferences,
        it turns around and changes UI process state (the enablement of the

        [iOS] "Copy" context menu action for attachment element does not work in Mail
        https://bugs.webkit.org/show_bug.cgi?id=211817
        <rdar://problem/58043110>

        Reviewed by Tim Horton.

        Implements support for copying an attachment element, via context menu actions. To achieve this, we first
        refactor code in WebCore that is currently responsible for converting an attachment element into a
        PromisedAttachmentInfo, which provides a handle to an UI-process-side API attachment object. We then use this
        helper in WebKit to send PromisedAttachmentInfo back to the UI process when handling the copy action from the
        context menu on iOS.

        On iOS, we then take this promised attachment info in the UI process, map it to an API::Attachment object, and
        use the file handle to create and write an NSItemProvider to the general pasteboard. (In the future, similar
        logic could be implemented on macOS as well to handle copying attachment elements by implementing a version of
        writePromisedAttachmentToPasteboard in PageClientImplMac. Currently, we fall back to treating this case as if
        we're copying a text selection containing a single attachment element).

        * UIProcess/API/ios/WKWebViewPrivateForTestingIOS.h:

        Add a new helper function to simulate an element action (_WKElementActionType) for an element at the given
        location. This is used by the new API test.

        Add an IPC message for the UI process to receive a PromisedAttachmentInfo, and copy it to the system pasteboard
        if it maps to an actual API::Attachment. For now, we only support copying data if the attachment is backed by
        a file wrapper in the UI process (as opposed to blob data written by the web process).

        (createItemProvider):

        Create a helper function to convert PromisedAttachmentInfo into an NSItemProvider. This is similar to
        `-_prepareToDragPromisedAttachment:`, but with a couple differences: (1) we only create an NSItemProvider
        instead of going through `WebItemProviderRegistrationInfoList`; (2) since there's no opportunity to clean up
        temporary after pasting, serialize the attachment data using `-serializedRepresentation`, and provide the
        attachment data instead of a file URL.

        Ideally, we would offer the data directly to the pasteboard so that even if Mail terminates, the contents of the
        pasteboard can still be provided when pasting; however, it doesn't seem like we can do this while being able to
        offer a suggested name for the item we're writing. Some other apps work around this limitation by writing the
        file name as plain text on the pasteboard, but this doesn't work then attempting to copy a plain text file that
        has a file name.

        CompositingCoordinator::syncDisplayState() method call is removed -- this call
        triggered any necessary layout, but that's already done through WebPage::updateRendering().

        Reviewed by Darin Adler.

        Neuter WKFrameIsFrameSet() / WKPageGetFrameSetLargestFrame() C API. This is only SPI and is only used for slightly
        different printing behavior in Safari. Framesets are no longer supported in HTML5 and are now super rare. Support
        for this C API adds quite a bit of code complexity and crashes such as <rdar://problem/60322282>, it just does not

        [iOS] Rebuild MobileGestalt cache if needed
        https://bugs.webkit.org/show_bug.cgi?id=211739

        Reviewed by Darin Adler.

        This patch was written by Geoff Garen and myself. Rebuild the MobileGestalt cache in the UI process if the
        MobileGestalt cache is stale. This should be done before starting a new WebContent process. If the cache
        is not rebuilt, every MobileGestalt query in the WebContent process will fail, since access to the daemon
        is denied.

        No new tests, since testing this is not trivial. It would involve deleting the MobileGestalt cache and
        making sure it is rebuilt afterwards. This could be an API test, but API tests are not supported on iOS
        devices.

        Reviewed by Yusuke Suzuki.

        Previously, we were calling Wasm::enableFastMemory() in WebProcess::initializeWebProcess().
        By then, it is too late because the JSC::Config and WTF::Config have already been
        frozen.  There is nothing special about Wasm::enableFastMemory() that it needs to
        be called this late.  This patch moves it into JSC::initializeThreading() where
        it belongs.

        This change also make the initialization of Wasm fast memory consistent with how
        we have always done it for the jsc shell i.e. it is initialized at the end of
        JSC::initializeThreading().

        To address the bug, this sets the default isNavigatingToAppBoundDomain
        value to be WTF::nullopt. This will allow app-bound behaviors until
        a navigation has been attempted, in which case it will fail or will
        update isNavigatingToAppBoundDomain to the correct value.

        fail; we only fail the deferring gesture recognizer once the web process has handled the touch event, and did
        not call `preventDefault()`.

        These additional failure requirements can cause preventable gestures to be linked together in the same gesture
        dependency subgraph; since each subgraph is reset only once all gestures in the subgraph have failed or ended,
        this might cause some gestures to be reset after a delay (rather than being reset immediately). To mitigate
        this, we divide the set of preventable gestures into multiple (currently, 2) subgraphs: one for gestures that
        are reset after a delay, and another for gestures that are immediately resettable. This way, immediately
        resettable gestures are able to reset and recognize again, without having to wait for other slower preventable
        gesture recognizers to reset.

        When fast-clicking is disabled (e.g. when loading a desktop web page on a mobile form factor, or when the
        viewport has been zoomed in), the blocking synthetic double tap gesture recognizer (that is, `WKContentView`'s
        `_doubleTapGestureRecognizer`) is enabled, and adds itself as a dynamic failure requirement to the content
        view's synthetic single tap gesture recognizer (`_singleTapGestureRecognizer`). In terms of the gesture
        dependency graph, this causes the single tap gesture to form an edge with the double tap gesture, which ends up
        uniting both deferring gesture recognizers under the same subgraph. This means UIWebTouchEventsGestureRecognizer,
        which should be one of the gestures in the immediately resettable subgraph, is now connected to the rest of the
        delayed resettable gestures, meaning that it cannot recognize until "slowly resettable" gestures such as the
        tap-and-half text selection gesture have also been reset. This delay causes touch events to be dropped, as is
        the case in this bug.

        To fix this, simply quarantine the single tap and double tap gestures inside their own subgraph by introducing a
        separate deferring gesture recognizer for them. When fast-clicking is enabled, this does not hinder the ability
        for the single tap gesture to fire in rapid succession, since the double tap gesture is disabled (and thus, not
        a part of the graph at all). when fast-clicking is disabled, then the double tap gesture will prevent the single
        tap gesture from being immediately reset anyways, due to the direct failure requirement between the double and
        single tap gesture.

        Doing this ensures that no other immediately resettable gesture (`UIWebTouchEventsGestureRecognizer` included)
        is accidentally blocked from immediately resetting due to being linked to the delayed resettable gestures by way
        of the synthetic single and double tap gestures.

        Clicking a tel:// link on iPad with a trackpad presents different UI than tapping on it
        https://bugs.webkit.org/show_bug.cgi?id=211686
        <rdar://problem/57941589>

        Reviewed by Wenson Hsieh.

        Previously, iOS WebKit had code in handleTap, handleTwoFingerTapAtPoint, and commitPotentialTap,
        which introspected the hit element /before/ dispatching the tap (or synthetic click) to the DOM,
        short circuiting all normal event handling machinery in order to prevent the default action
        and present the Data Detectors UI for the given link.

        There's one immediate problem with this, which is that there is no similar code in the direct
        click event handler path, which we now use for trackpad/mouse input on iPad. There's also a
        secondary problem (which we have not seen in practice), which is that pages cannot preventDefault
        to avoid launching the Data Detectors UI on a link, like they could to prevent an ordinary
        link from being followed.

        In order to resolve both issues and reduce duplication of logic, move the code that introspects
        the element and invokes Data Detectors UI from high-level WebKit event dispatch code (where it
        doesn't really belong) down to WebCore's default click event handler for anchors, right next to
        the code that would ordinarily cause a navigation. This way, no matter how we get here, whether
        by synthetic click or real click, we'll invoke the Data Detectors UI.

        One alternative considered at length: we could actually let the navigation happen, and instead
        handle the switch in navigation policy code, but there are a few reasons that did not seem ideal:
        1) We'd need to plumb platform-specific data structures through a ton of FrameLoader code.
        2) Clients often block non-HTTP(S) navigations, so in order to keep the feature functional,
           we'd have to disregard the client's policy decision, defeating much of the purpose of making
           use of the navigation mechanism in the first place.

        The main search field on the mobile version of this website begins offscreen, with a CSS transform that moves it
        to the far right; tapping the button element that (visually) has a search-field-like appearance on the front
        page programmatically focuses the real offscreen search field, and animates it onscreen by changing the CSS
        transform attribute to remove the x-axis translation.

        On iOS, the caret rect is computed and sent to the UI process via editor state updates; however, the editor
        state is computed immediately after focusing the input field. As such, the caret rect at this moment is computed
        in the middle of the animation, leaving it stuck in an unpredictable location.

        To fix this, add plumbing to call into the WebKit client layer when an animation has ended. On iOS, if the
        selection is visible (i.e. a ranged selection, or editable caret), then check to see whether the element that
        has finished animating contains either endpoint of the selection. If so, then schedule a followup editor state
        update to push updated selection information to the UI process.

        REGRESSION(r259209) Webview's pending URL is null after restoring session state
        https://bugs.webkit.org/show_bug.cgi?id=211626
        <rdar://problem/62992262>

        Reviewed by Alex Christensen.

        The issue was that WebPageProxy::goToBackForwardItem() would behave differently whether
        the page has a running process or not. In particular, when the page did not have a
        running process, goToBackForwardItem() would return early and call launchProcessWithItem()
        instead. Unlike goToBackForwardItem(), launchProcessWithItem() would fail to set the
        pending API request.

        To address the issue, I am getting rid of launchProcessWithItem() and merging its logic
        into goToBackForwardItem() instead. Both methods shared a lot of code anyway and having
        2 separate code paths that may diverge is error prone.

        Change is covered by new API test.

        [iOS] AuxiliaryProcessProxy::sendWithAsyncReply() should prevent auxiliary process suspension while processing the IPC
        https://bugs.webkit.org/show_bug.cgi?id=209928

        Reviewed by Youenn Fablet.

        AuxiliaryProcessProxy::sendWithAsyncReply() should prevent auxiliary process suspension
        on iOS while processing the IPC. If the process is suspended either before or during
        the IPC, this could result in hangs. This is a speculative fix for the flaky timeouts
        we see on many tests on iOS only. We know that missing activities with
        sendWithAsyncReply has caused test timeouts in the past (Bug 211421).

        Sending WebRTC network packets should not go through the main thread
        https://bugs.webkit.org/show_bug.cgi?id=211291

        Reviewed by Eric Carlson.

        Following on receiving RTC packets from a background thread, we also send RTC packets from a background thread.
        Creation of the sockets also happens in a background thread.
        LibWebRTCNetwork is getting the connection whenever a new connection to network process is created.
        It will then hop to the RTC network thread to set the IPC connection to the libwebrtc socket factory.

        At creation of the socket, we get the IPC connection to the network process and keep a ref in the RTC socket.
        In case network process crashed and the IPC connection of the RTC network is null, we hop to the main thread to create a new IPC connection.
        This will fail the creation of the socket (as well as new ones as well) as long as the IPC connection to network process is not valid again.

        Covered by existing tests.

        [ContentObservation] Shutterstock search bar is not activated on the first tap
        https://bugs.webkit.org/show_bug.cgi?id=211529
        <rdar://problem/58843932>

        Reviewed by Simon Fraser.

        Shutterstock has a “initial click” action which converts some “actionable” elements (<a>) to some other “actionable” elements (<button>).
        If this initial click also happens to be on an element that triggers content observation (input), we see those changes as actionable content and not proceed with the click event (stay at hover).
        Any subsequent click works as expected.
        It’s very difficult to eliminate such false positives since all we see is that some "actionable" content is going away while some "actionable" content is being created.
        This quirk ensures that the first tap on the page does not trigger content observation. (It also means that any hover menu gets submitted on the first tap, but apparently
        the Shutterstock top menu bar works fine with click events.)

        Better surfacing of the presenting parent PID in the Network process
        https://bugs.webkit.org/show_bug.cgi?id=211495
        <rdar://problem/62917205>

        Reviewed by Youenn Fablet.

        In Bug 205295, NetworkResourceLoader logging was improved, with one of
        the changes being that the PID of parent process that invoked the
        Network process was logged at the start of
        NetworkResourceLoader::start(). However, there was an execution path
        that skipped calling start()
        (NetworkConnectionToWebProcess::scheduleResourceLoad ->
        NetworkResourceLoader::startWithServiceWorker ->
        serviceWorkerDidNotHandle -> restartNetworkLoad -> startNetworkLoad),
        and so the the logging would not show the parent PID. This logging is
        needed for diagnostic purposes, so tweak the logging a little bit more
        in order to ensure we emit it. In this change, logging is added to
        various loading-related NetworkConnectionToWebProcess entry points
        (not just scheduleResourceLoad) in order to (a) ensure we emit the
        logging we want and (b) to give a clearer picture of what operations
        are being invoked in the Network process.

        No new tests -- no new or changed functionality.

        Exempt app-bound domains from ITP's website data deletion and third-party cookie blocking between themselves
        https://bugs.webkit.org/show_bug.cgi?id=210674
        <rdar://problem/61950767>

        Reviewed by Chris Dumez.

        This change forwards information about app-bound domains to ITP and web
        processes so that they can be exempt from website data deletion and
        third-party cookie blocking between themselves.

        App-bound domains are configured statically and apply to all website
        data stores. Therefore the setting needs to be forwarded to all
        website data stores and ITP functionality in all network and web
        content processes. This is done through the new static function
        WebsiteDataStore::setAppBoundDomainsForITPIfInitialized().

        Since app-bound domains are loaded lazily from disk and on a background
        thread, this patch forwards them in ResourceLoadStatisticsParameters if
        they've already been loaded. Then every time app-bound domains are
        updated, they are forwarded to ITP. This ensures that ITP will have them
        as soon as possible.

        Setting app-bound domains for the purposes of ITP automatically switches
        ITP's cookie blocking policy to the new
        WebCore::ThirdPartyCookieBlockingMode::AllExceptBetweenAppBoundDomains.
        This is done in WebResourceLoadStatisticsStore::setAppBoundDomains().

        The C API changes are for test purposes.

        With the timeout, an attempt to write to the database when another

        Add com.apple.runningboard.assertions.webkit entitlement to iOS Simulator builds so that
        we can take RunningBoard assertions on those platforms too.

        While doing this, I found that we were not adding the entitlements properly for simulator
        builds. For simulator builds, entitlements go into an __entitlements section of the binary,
        rather than in the signature. Use CODE_SIGN_ENTITLEMENTS directive in xcconfig so that

        Reviewed by Darin Adler.

        A few problems:

        - There is short time during page creation where a WKWebView created
        with _clipsToVisibleRect=YES would not yet have sent its viewExposedRect
        to the Web Content process, and if we end up constructing tiles during
        that time, we can make way too many, bogging down the process (or crashing).

        Fix this by always keeping track of the viewExposedRect (on WebPageProxy,
        instead of the somewhat-more-transient DrawingAreaProxy) and sending it
        to the Web Content process in the WebPage creation parameters, to entirely
        remove this window.

        - Even when the viewExposedRect successfully gets to the Web Content
        process, it can still end up wildly wrong: the DrawingArea was tasked with
        watching scrolling changes, applying the scroll offset to the viewExposedRect,
        and pushing it to FrameView in content coordinates.

        It turns out that this was all unnecessary, as we need viewExposedRect
        in root view coordinates (same space as visibleContentRect, which we
        intersect it with), and we just didn't notice because all clients of
        _clipsToVisibleRect: expand the view to its layout size and insert
        a scrolling view outside the web view, and so don't use our scrolling.

        Avoid this conversion and complexity entirely; I tested Mail and Books
        where there is no impact (other than fixing the original bug), and also
        a custom test app with a scrollable WKWebView inside a NSScrollView,
        which improved significantly.

        [iOS] ProcessThrottler fails to re-take ProcessAssertion if the previous one was invalidated

        Reviewed by Jer Noble.

        Our ProcessAssertions may get invalidated upon backgrounding of the app. When the app becomes
        foreground and the ProcessThrottler tries to take a Foreground assertion as a result, it would
        incorrectly think it already had such assertion and not do anything, even though the previous
        one is no longer valid. As a result, the child processes would stay suspended even though the
        app was foregrounded.

        To address the issue, add a isValid() method to ProcessAssertion() and check it in
        ProcessThrottler::setAssertionType() to determine if we need to re-take an assertion or not.
        We also invalidate all pending ProcessThrottler activities upon ProcessAssertion invalidation
        for good measure. This way, the holders of these activities will be able to rely on
        Activity::isValid() to determine if they need to re-take their activities or not.

        REGRESSION: Double tap dispatches one click event on iOS 13.4 when it would dispatch two on iOS 13.3
        https://bugs.webkit.org/show_bug.cgi?id=211179
        <rdar://problem/62594779>

        Reviewed by Tim Horton.

        https://trac.webkit.org/r253267 introduced deferring gesture recognizers as a way to handle preventable (non-
        passive) touchstart events without blocking the UI process. These deferring gesture recognizers work by having
        other gesture recognizers at or below WKWebView (with few exceptions) require the failure of these deferring
        gestures. These gestures transition to possible state when beginning a touch inside a non-passive touch event
        handling region, and transition to either failed or ended state (depending on whether `preventDefault()` was
        called) after the web content process finished handling the touch event.

        However, this means that the resulting dependency graph now has an edge between each gesture under WKWebView and
        one of the deferring gesture recognizers, due to these new failure requirements. Since gestures that have been
        recognized or have failed don't get reset until all other gestures in the same dependency subgraph have also
        recognized or failed, some gestures (such as the synthetic single tap gesture recognizer in this bug) might not
        be resetting as soon after ending as they did before, since they may be connected to other gesture recognizers
        that are still in possible state by way of the failure requirements added by the new deferring gestures.

        I was already aware of this problem in r253267, and attempted to solve this by bisecting the gesture dependency
        graph into two subgraphs: one containing all the one-finger multi-tap gestures that are reset after a lengthy
        delay, and another containing everything else. To do this, I added two different deferring gesture recognizers:
        one for immediately resettable gestures (meant for gestures in the latter subgraph), and another for gestures
        that are reset after a delay (meant for gestures in the former subgraph).

        Unfortunately, unrelated changes around text interactions in UIKit in iOS 13.4 caused the tap-and-a-half
        gesture for selecting a range of text to now have a delayed reset; this means that gestures in the "immediately
        resettable" gesture subgraph are all forced to wait on the tap-and-a-half text interaction gesture before
        resetting, which causes the bug here, since the synthetic single tap gesture is in this "immediately resettable"
        gesture subgraph.

        To mitigate this, this patch pushes the tap-and-a-half text selection gesture, along with the loupe gesture,
        context menu relationship gesture, and drag lift gestures (i.e. the other gestures that are connected to the
        tap-and-a-half gesture via failure requirements) out of the "immediately resettable" subgraph, and into the
        "delayed" subgraph.

        Reviewed by Per Arne Vollan.

        In r260932 I added an assertion to confirm that a sandbox extension was successfully consumed. This triggered three
        test failures because those tests attempt to pass a sandbox extension from the WebContent process to the UIProcess.

        After speaking with the Sandbox team, I learned that an unsandboxed program that attempts to consume a valid
        sandbox extension will return 0. Sandboxed processes either receive -1 (for error), or a handle representing the
        newly added extension (so that it can be removed when no longer needed).
        
        Since the TestWebKitAPI (and WebKitTestRunner) processes are not sandboxed they receive a zero return value here.

        We should recognize this as a valid and expected result. We should also consider making some form of sandboxed
        driver for WebKit.

        Reviewed by Eric Carlson.

        The function WebPage::textInputContextsInRect is very specific to a client on iOS.
        Although it's tempting to keep this cross-platform because its implementation does
        not make use of iOS-specific technologies it does a very specific operation, the
        result of which is a list of contexts to editable elements on the page. The contexts
        provide enough info for the specific iOS client, but not enough to ever be useful
        to any other client. Therefore move it to WebPageIOS.mm.

        Only Mac and iOS were ever using this function. The former only for testing purposes
        that have since been removed.

        A side effect of this change is that I also move WebPageProxy::textInputContextsInRect()

        [iOS][WK2] Drop process assertion logic for holding locked files
        https://bugs.webkit.org/show_bug.cgi?id=206910

        Reviewed by Alex Christensen.

        Drop process assertion logic for holding locked files as it is causing issues and
        should no longer be needed.

        The intention of this code was that the Network Process would send a
        SetIsHoldingLockedFiles(bool) IPC to the UIProcess whenever there are pending
        SQLite transactions and the UIProcess would then take a process assertion on behalf
        of the WebProcess (or release it) to prevent / allow suspension.

        This approach has some issues:
        1. It was noisy in terms of IPC
        2. Because it relies on an IPC to the UIProcess to keep running, it was inherently
           racy
        3. We already have logic to deal with suspension in the network / web processes.
           The UIProcess sends a PrepareForSuspension IPC to its child processes. In turn,
           those processes will make sure to suspend their database threads to prevent any
           further database work. The child processes would then respond to the
           PrepareForSuspension IPC to let the UIProcess know they are ready to suspend.
           The 2 approaches were conflicting, because after the PrepareForSuspension IPC is
           sent, the child process could process a transaction and send the
           SetIsHoldingLockedFiles() IPC to the UIProcess which would incorrectly cancel the
           suspension.

        Organize the code to reflect reality: editor state only has marked text rects if layout is
        up-to-date. So, move these fields to from EditorState to EditorState::PostLayoutData.

        While I am in this area of the code I also moved the editor state originIdentifierForPasteboard
        to the top of the struct as it is aesthetically more pleasing to me to have the post layout
        data last. It likely also produces better bit packing though this wasn't my primary motivation.

        [MacCatalyst] Dynamic access to accessibility services is incomplete 
        https://bugs.webkit.org/show_bug.cgi?id=211100
        <rdar://problem/62133491>

        Reviewed by Darin Adler.

        Testing of MacCatalyst-based apps shows that using dynamic sandbox extensions to support accessibility
        features is incomplete. In addition to the 'com.apple.cfprefsd.daemon' process needed on macOS and iOS,
        we also need access to 'com.apple.cfprefsd.agent'.

        This can only be tested manually in a MacCatlyst build, though existing accessibility tests will
        confirm no regressions in iOS and macOS.

        The changes are as follows:
        1. Change WebProcessCreationParameters::preferencesExtensionHandle to a handle array.
        2. Register (and unregister) for the accessibility enabled notification in MacCatalyst.
        3. Open a connection 'com.apple.cfprefsd.agent' (in addition to the existing 'com.apple.cfprefsd.daemon')
           in MacCatalyst builds.

        Prevent WebPasteboardProxy IPC messages from unconditionally requesting pasteboard types
        https://bugs.webkit.org/show_bug.cgi?id=211061
        <rdar://problem/62088185>

        Reviewed by Tim Horton.

        Tighten IPC message handling in WebPasteboardProxy, such that a web content process is unable to arbitrarily
        request pasteboard types (and other metadata that depends on pasteboard types, such as the number of files
        on the pasteboard).

        This extends the mechanisms added in r259151 by distinguishing between allowing the web process to request
        type information from the pasteboard, and allowing the web process to request both types and data. In the
        case of drag and drop, the former is required by the web process from the moment the drag session enters
        the platform web view; however, the latter is required only after a drop is performed.

        We utilize this new check, `canAccessPasteboardTypes`, in seven existing IPC message handlers that either
        directly return the list of types, or return metadata from which pasteboard types may be deduced.

        See below for more details; covered by existing API and layout tests.

        Split the pasteboard access check into two helpers: one to determine whether the web process is allowed to

        (WebKit::WebPasteboardProxy::canAccessPasteboardTypes const):

        Return true as long as the accessType is nonnull; this is because either `Types` or `TypesAndData` is

        that is used to represent which web processes are allowed to access certain changeCounts, for a given pasteboard name.
        Instead of maintaining a changeCount and set of processes, we now maintain a changeCount and list of (process, access
        type) pairs. Each item in this list tracks whether the process that has been granted access should be allowed to read
        only pasteboard types, or both types and data.

        Reviewed by Darin Adler and Chris Dumez.

        There was an out-of-date comment suggesting we needed to use a semaphore, but we've since added these in the destructor:
        RELEASE_ASSERT(!m_statisticsStore);
        RELEASE_ASSERT(!m_persistentStorage);
        This indicates that flushAndDestroyPersistentStore is called before the destructor, at which time it is safe to add a reference to keep it alive.
        WebResourceLoadStatisticsStore is also marked as WTF::DestructionThread::Main so this should do everything we need.
        We also flush these databases to disk before closing like we did cookies.

        In order to keep tests working as they are, I needed to make recreateResourceLoadStatisticStore have a CompletionHandler and have all
        WebResourceLoadStatisticsStores share the same queue to serialize background tasks between WebResourceLoadStatisticsStores with and without database stores
        sequentially to avoid opening a SQLiteDatabase before the previous WebResourceLoadStatisticsStore had closed it.

        When an iframe is detached from the DOM, it is no longer exposed as a browsing context
        and it's not possible to Evaluate JavaScript or perform other commands with it. This
        patch adds frame lifecycle monitoring so that pending script evaluations are cancelled
        with FrameNotFound as soon as the iframe is detached from the DOM. This change also avoids
        running more commands with the frame if it's detached from its DOMWindow and ready to be GC'd.

        Clean up QuickLookThumbnailLoader

        Reviewed by Darin Adler.

        The following items are cleaned up:
        - Extract `using PlatformImage` into QuickLookThumbnailLoader.h,
          rename to `CocoaImage` and use to get rid of duplicate
          code.
        - Change `id` to `instancetype` for -init methods.
        - Add `atomic` keyword to @property definitions that were using
          it as the default.  (Use of atomic properties is rare in
          WebKit, so being explicit avoids a scenario where it looks
          like `nonatomic` was left off by accident.)
        - Change @property definitions to `readonly` that are never
          written to outside of QuickLookThumbnailLoader.mm.
        - Delete unused @property definitions.
        - Change method declarations into read-only @property
          definitions.
        - Re-declare atomic read-only @property definitions in
          QuickLookThumbnailLoader.h as read-write definitions in

        Clean up QuickLookThumbnailLoader
        <https://webkit.org/b/210814>

        Reviewed by Darin Adler.

        The following items are cleaned up:
        - Extract `using PlatformImage` into QuickLookThumbnailLoader.h,
          rename to `CocoaImage` and use to get rid of duplicate
          code.
        - Change `id` to `instancetype` for -init methods.
        - Add `atomic` keyword to @property definitions that were using
          it as the default.  (Use of atomic properties is rare in
          WebKit, so being explicit avoids a scenario where it looks
          like `nonatomic` was left off by accident.)
        - Change @property definitions to `readonly` that are never
          written to outside of QuickLookThumbnailLoader.mm.
        - Delete unused @property definitions.
        - Change method declarations into read-only @property
          definitions.
        - Re-declare atomic read-only @property definitions in
          QuickLookThumbnailLoader.h as read-write definitions in

          This also fixes a theoretical leak found by the clang static
          analyzer.
        - Remove `shouldWrite` @property.  It is only used within

        - Change `identifier` and `thumbnail` to @property declarations.
        * UIProcess/QuickLookThumbnailLoader.mm:

        Scrolling with background-attachment: fixed needs to trigger repaints
        https://bugs.webkit.org/show_bug.cgi?id=193893
        <rdar://problem/47587017>

        Reviewed by Dean Jackson.

        When scrolling an overflow scroll which has "background-atttachment:fixed" in the content,
        the node will have non-empty synchronous scrolling reasons. In this case we need to
        send the scroll to the main thread, and trigger a repaint on scroll.

        If handling the wheel event on the scrolling thread determines that the scroll must be sent
        to the main thread, EventDispatcher::wheelEvent() does so in the callback function.

        To trigger the repaint, RenderLayer::scrollTo() asks the composited layers backing whether
        the node has synchronous scrolling reasons; this is implemented by asking the scrolling
        coordinator.

        When SpeculativeLoadManager is destroyed, properly clean up its PendingFrameLoads
        https://bugs.webkit.org/show_bug.cgi?id=210759
        <rdar://problem/62056856>

        Reviewed by Darin Adler.

        Recent work on the resourceLoadStatistics layout tests increased the amount we swap out the WebsiteDataStore.
        When this happens, the NetworkSession is eventually destroyed in the NetworkProcess, sometimes when running the next test.
        An assertion was firing in the PendingFrameLoad destructor because it hadn't been marked as complete when it was destroyed.
        Rather than remove the assertion, when we destroy the SpeculativeLoadManager (which only happens when a WebsiteDataStore
        is destroyed) during a speculative pending frame load, just mark the pending frame load as complete because it is being cancelled.
        Marking the pending frame load as complete can tell the SpeculativeLoadManager to mutate m_pendingFrameLoads, which we don't want
        to do while iterating, so copy the RefPtrs into a Vector first then iterate that to get them all.

        This fixes an assertion that was sometimes hit in http/tests/resourceLoadStatistics/strip-referrer-to-origin-for-prevalent-subresource-redirects-database.html
        but only after running other tests that had initiated speculative pending frame loads.  This was ostensibly started by r260322 but is quite unrelated.

        [iOS] Refactor WebKit media playback process assertion logic to minimize chances of leaking them
        https://bugs.webkit.org/show_bug.cgi?id=210670

        Reviewed by Geoffrey Garen.

        Refactor WebKit media playback process assertion logic to minimize chances of leaking them. In particular,
        the following changes were made:
        1. Instead of the WebProcessPool having a HashMap of media playback process assertions for
           the WebProcess, we now store the assertion on the WebProcessProxy object itself. This is
           less likely to get out of sync and leak.
        2. Add a RefCounter to the WebProcessPool to count WebProcesses that have audible media.
           Whenever a WebProcess starts or stops playing audible media, it merely grabs a RefCounter
           token or releases it. The WebProcessPool relies on this counter to decide whether or not
           to take a media playback assertion on behalf of the UIProcess. Since this is token-based
           and the token is stored on the WebProcessProxy object, it makes it less likely to leak
           the assertion.
        3. The WebProcessProxy object now has a AudibleMediaActivity data structure wrapping both
           its media playback assertion and its WebProcessWithAudibleMediaToken that it got from
           the WebProcessPool. When the WebProcess shuts down (normally or due to crash/termination),
           we make sure to clear this data structure.
        4. Make sure that the WebProcessProxy updates its AudibleMediaActivity whenever a page is
           removed from the WebProcess.

        Fix WebUserContentControllerProxy vs ContentWorld lifetime
        https://bugs.webkit.org/show_bug.cgi?id=210700

        Reviewed by Alex Christensen.

        Covered by API test.
        
        WebUserContentControllerProxy currently keeps all of its associated API::ContentWorlds alive via RefPtrs.
        
        This is despite the fact that all of the associated WebScriptMessageHandlers, UserScripts, and 
        UserStyleSheets already keep their associated API::ContentWorlds alive.

        It then decideds to tell WebProcesses to forget a content world after all of its clients are removed.
        
        Unfortunately, content worlds are used for more than just content controller stuff. They're used for direct
        JavaScript evaluation as well.
        
        So a client could:
          - Add a script message handler in a content world.
          - Evaluate JavaScript in that content world, setting up some persistent state.
          - Remove the script message handler.
          - Find that their persistent state from the JavaScript evaluation is gone from that world, even though they
            still retain a usable handle to that world.
        
        The only party who has any business managing the lifetime of an API::ContentWorld is the API::ContentWorld itself.
        
        Making this change is:
          1 - Nice cleanup

        NetworkProcessProxy was trying to keep a map of WebsiteDataStores, but it wasn't as accurate as the one WebsiteDataStore was maintaining.
        Use the latter map instead and client certificate authentication works.  Otherwise, the credential isn't serialized correctly.

        NetworkSessionCocoa should request client certificate only once per host/port

        NSURLSession creates more than one TCP connection to a server when using HTTP 1.1.
        Each TCP connection with TLS generates a didReceiveChallenge to do the server trust evaluation of the certificate chain.
        If the server requests a client certificate in the TLS handshake, it also generates a didReceiveChallenge to request client
        certificates as well.  This is an implementation detail of our networking.  We should not actually ask the WKNavigationDelegate
        for client certificates more than once per host/port.  We should remember the credential and give it to NSURLSession immediately
        if we have used this credential in the past for a task that has received bytes (either a response or a redirect).  If the TLS
        handshake fails, we should not reuse that same certificate automatically.

        [iOS] Refactor WebKit uploads process assertion logic to minimize chances of leaking them
        https://bugs.webkit.org/show_bug.cgi?id=210664
        <rdar://problem/61751982>

        Reviewed by Geoff Garen.

        To minimize chances of leaking "WebKit uploads" process assertion, the following refactoring
        was done:
        1. WebKit upload assertions are now held by NetworkProcessProxy instead of the WebProcessPool.
           This makes more sense since uploads are tied to a particular network process. In base of
           a network process crash, we would not want those assertions to persist for example.
        2. Store all upload assertions (UIProcess + NetworkProcess + WebProcesses) into a single
           UploadActivity data structure that can easily be cleared. Make sure we clear it on network
           process crash.
        3. No longer on the WebProcess to send IPC whenever its has pending uploads or not. Instead,
           have the network process send such IPC. This makes more sense, especially now that all
           webkit upload process assertions are now stored on NetworkProcessProxy. It also makes it
           so that we deal properly with WebProcess crashes. In case of a WebProcess crash, its
           connection to the network process will get closed. NetworkConnectionToWebProcess::didClose()
           gets called and causes all NetworkResourceLoader objects for this connection to get
           destroyed. As a result, the network process will properly notify the UIProcess that this
           process no longer has any upload in progress.

        Reviewed by Eric Carlson.

        When a page is showing an alert(), all non-synchronous messages will be blocked until the sync XPC for alert()
        ends. And when exiting fullscreen, we block completing the fullscreen exit animation until a repaint XPC completes.
        So a page that is showing an alert() will never fully exit element fullscreen mode.

        On iOS, we fixed this behavior by exiting fullscreen mode whenever the page shows an alert() or prompt(). We should
        bring this behavior to macOS as well.

        REGRESSION(r260081) Broke iOS PLT due to InjectedBundle initialization (edit)

        <rdar://problem/61838584>

        Reviewed by Darin Adler.

        The changes in r260081 began enforcing NSSecureCoding best practices, triggering
        a bug in InjectedBundleMac.mm, which is used by iOS as well.

        This patch does the following:

        1. Delays parameter decoding until we use the appropriate InjectedBundle mechanism
           for expressing the valid classes to use in the Unarchiver.
        2. Removes a temporary workaround needed to get PLT running on iOS again.

        This patch also moves the check of the CFBundleGetFunctionPointerForName slightly earlier
        so we can use a single function pointer check, and only invoke the parameter decoding
        if we are using the C API.
        
        If not, we delay parameter decoding until we have constructed the WKWebProcessPlugIn
        object so we can consume it's 'additionalClassesForParameterCoder' before calling
        its initialization method.

        setAcceleratedCompositingRootLayer is called from updateAcceleratedCompositingMode,
        because the layer hosting mode changed (Books appears to use app-hosted layers),
        it incorrectly identified the root layer change as a process swap, resulting
        in the correct layer never being unhidden.

        This is enough mistakes that I'm going to try a different approach:
        put setAcceleratedCompositingRootLayer back to the way it was before, where
        it immediately updates the layer without any smarts, remove
        setAcceleratedCompositingRootLayerAfterFlush, because it's no longer necessary,
        and add enterAcceleratedCompositingWithRootLayer, which is specifically only
        called in the case where DrawingArea will for-sure send us a follow-up
        (didFirstLayerFlush) that will unhide the root layer.

        When we process swap, the layer swap/unhiding for the new hosted layer is gated by the
        DidFirstLayerFlush IPC. But actually sending this IPC can be head-of-line blocked for an
        arbitrarily long time because we append it to the queue of messages for the main run loop to
        process. In some cases, e.g. for the NYT PLT content, this blocks first paint by 200 ms
        while the WebProcess main thread is busy doing other things (like executing deferred
        scripts).

        To fix this, use a CATransaction commit handler to send the IPC right after we commit.

        might be affected by the fullscreen mode.

        We need to call WebPageProxy::setNeedsDOMWindowResizeEvent() to fire the "resize" event
        in the repaint callback after the exiting fullscreen process is completed and the
        possible layout change due to exiting fullscreen is done. Otherwise the size calculation

        [iPadOS] Some pages indefinitely zoom in and out due to idempotent text autosizing
        https://bugs.webkit.org/show_bug.cgi?id=210551
        <rdar://problem/56820674>

        Reviewed by Tim Horton.

        On a non-responsive web page with one or lines of non-wrapping text of a specific length (just under 1920px),
        it's possible for the combination of idempotent text autosizing heuristics and viewport shrink-to-fit to cause
        the single line of text to grow and shrink in size indefinitely, and additionally cause the initial scale to
        thrash between multiple values indefinitely. This manifests in the entire page repeatedly zooming in and out
        immediately after page load.

        Consider the following scenario:

        (1) A viewport configuration change (e.g. due to parsing the viewport meta tag) schedules the timer to reset
            idempotent text autosizing. Let's suppose the page has a really long line of non-wrapping 12px text that is
            below 1920px wide.

        (2) The timer fires, invalidating styles and recomputing text autosizing given the current initial scale. The
            current initial scale is below 1, since ViewportConfiguration will attempt to shrink to fit the page to
            avoid horizontal scrolling. This causes text autosizing to boost the long line of text to a larger value
            (let's say 17px).

        (3) The next time we perform style recomputation and layout, we discover that the content width of the page is
            now larger than 1920px, which is the maximum width which we'll attempt to shrink to fit; when computing
            initial scale, we give up trying to shrink down to avoid making the inital scale too small, and instead just
            keep it at 1.

        (4) This change in viewport configuration then schedules another idempotent text autosizing reset. When this
            timer fires, it sees that the initial scale is now 1, which means that the text is no longer boosted, so we
            make the single line of text small again (12px).

        (5) After the next style recomputation and layout, this causes the content width of the page to dip below the
            1920px threshold, causing the initial scale to dip below 1 again. As detailed above, this schedules another
            idempotent text autosizing update, which now boosts font size once again, and the cycle continues.

        To fix this, instead of consulting the initial scale (`ViewportConfiguration::initialScale()`) when computing
        the boosted font size for idempotent text autosizing, we can instead ask for the initial scale ignoring content
        size (`ViewportConfiguration::initialScaleIgnoringContentSize()`). This prevents changes in content size due to
        idempotent autosizing from affecting the idempotent autosizing heuristic (through the different initial scale),
        and ensures that this method of text autosizing actually remains idempotent.

        We recently discovered that the system sandbox framework version does not always change
        when breaking changes in the sandbox format are made. This can lead to the precompiled
        version of a sandbox not working properly when a sandbox version changes.

        To guard against this, make the following changes:

        1. Compare the SANDBOX_BUILD_ID in place when the sandbox was compiled to the value on
           the current system. SANDBOX_BUILD_ID, which is a GUID, is always regenerated when the
           sandbox framework is rebuilt.

        2. Compare the OS version in place when the sandbox was compiled to the value on the current
           system. This will trigger us recompiling sandboxes even when the sandbox framework did not
           change, but this is a small performance cost that would only happen after a software update.

        register additional classes that are safe for serialization.

        Reviewed by Tim Horton.

        Remove the internal WebKit2 feature; this was introduced around iOS 9 to unconditionally force pages to shrink
        to fit if they specified a responsive viewport, to avoid horizontal scrolling.

        Nowadays, this behavior is instead controlled by the `-[WKWebView _allowsViewportShrinkToFit]` SPI, which
        ensures that this shrink-to-fit preference is updated in sync with the visible content rect update lifecycle; it
        is currently used by Safari to scale web pages down to fit in smaller multitasking viewports.

        In contrast, this preference has no internal clients. Instead of maintaining two different ways for clients to
        control shrink-to-fit behavior, remove support for the preference and make it a no-op.

        First render after a process swap does not use accelerated rendering
        https://bugs.webkit.org/show_bug.cgi?id=210297
        <rdar://problem/61432515>

        Reviewed by Antti Koivisto.

        To prevent flashing on navigation when process-swapping, we were delaying the
        DrawingAreaProxy::EnterAcceleratedCompositingMode IPC message from the WebProcess
        to the UIProcess, until the new page is ready to display. The reason we did this
        is that the EnterAcceleratedCompositingMode IPC message ends up setting the root
        CALayer so the new content would become visible on screen. However, another side
        effect of this is that we would also delay the point until which we get
        accelerated rendering, which would negatively impact early page load performance.

        To address the issue, the following changes were made:
        1. We no longer delay the DrawingAreaProxy::EnterAcceleratedCompositingMode IPC.
           In non process-swap cases, we send it as soon as the DrawingArea is constructed.
           In process-swap cases, we send it as soon as we commit the load since this is
           when the provisional drawing area gets committed and happens before we have
           any content to paint.
        2. In the UIProcess, when we get the DrawingAreaProxy::EnterAcceleratedCompositingMode
           IPC and we already have a root layer, we add the new one behind the existing one
           instead of replacing the existing one. As a result, the new layer will get
           accelerated compositing but will not be visible on screen yet.
        3. Introduce a new DrawingAreaProxy::DidFirstLayerFlush IPC which gets send at the
           point where we used to send the EnterAcceleratedCompositingMode IPC, meaning where
           the new content is ready to display. When the UIProcess receives this IPC, it
           actually replaces the root layer with the new layer so that the new content visible.

        After this patch, our CALayers get accelerated compositing right away after a
        process-swap but we still do not see any blank-flashing on navigation.

        [iOS] Unable to select text by tap-hold or double tap-hold when allowsLinkPreview property is set to NO
        https://bugs.webkit.org/show_bug.cgi?id=210191
        <rdar://problem/60454016>

        Reviewed by Tim Horton.

        In iOS 13.4, UIWKTextInteractionAssistant no longer uses the (misleadingly-named) "force press" gesture to drive
        text selection when performing a long press. Instead, it now uses the UIVariableDelayLoupeGestureRecognizer,
        i.e. the text interaction assistant's loupe gesture recognizer.

        The highlight long press gesture, which is only enabled when `allowsLinkPreview` is set to `NO`, is currently
        allowed to recognize alongside the force press gesture but not the loupe gesture. This means that when link
        previews are disabled, we'll end up allowing the highlight long press gesture to prevent text selection. A
        similar issue already exists for the tap-and-half gesture as well.

        To fix this, we allow the highlight long press gesture to recognize alongside both gestures.

        Test: editing/selection/ios/select-text-with-link-preview-disabled.html

        * UIProcess/ios/WKContentViewInteraction.mm:
        (tapAndAHalfRecognizerClass):

        While UITapAndAHalfRecognizer is declared in a UIKit private header, it is (perhaps unintentionally) not
        exported, so attempting to call +[UITapAndAHalfRecognizer class] leads to a linker error. Work around this by
        dynamically grabbing the `Class` from the class name.

        The tap and half gesture recognizer is private in UIKit and only used for text interaction gestures, so we
        always want the highlight long press gesture to be able to recognize alongside it.

        (-[WKContentView gestureRecognizer:shouldRecognizeSimultaneouslyWithGestureRecognizer:]):

        Also clean up some existing code by replacing `.get().`s with Objective-C bracket operators.
