        Load WebInspectorUI resources via the inspector-resource:// scheme.
        Moving off of file:// URLs will allow for a tighter sandbox and
        will fix the longstanding issue that Web Inspector's settings are
        part of the file:// scheme and cleared when Safari clears website data.

        This also has the effect of resetting Web Inspector settings since
        they are no longer associated with file:///.

        Loading via this scheme is exercised by existing inspector tests.

        Handle empty bound size during animated resizing
        https://bugs.webkit.org/show_bug.cgi?id=223446

        Reviewed by Tim Horton.

        We don't allow empty bounds in animated resizing: when that happens, we would cancel it. However, a set of 
        updates involving empty bounds can be merged to a valid update. For example, two changes of frame size 
        [1] (0, 0, 100, 100) => (0, 0, 0, 50) [2] (0, 0, 0, 50) => (0, 0, 50, 50) can be viewed as single change 
        (0, 0, 100, 100) => (0, 0, 50, 50), which is valid. We used to ask SPI clients to ensure each update is valid, 
        but sometimes the frame change is not under client's control. For example when client uses auto layout, empty 
        frame seems to be a valid mid product.

        To handle this case, we can store the old bounds, and actually perform animated resizing on when new valid 
        bounds show up. For the example above, we would store (0, 0, 100, 100) on [1] and use it to resize from 
        (0, 0, 100, 100) to (0, 0, 50, 50) on [2].

        [iOS] editing/selection/character-granularity-rect.html fails on certain internal configurations after r274610
        https://bugs.webkit.org/show_bug.cgi?id=223447

        Reviewed by Devin Rousso.

        On versions of iOS where `ENABLE(IMAGE_EXTRACTION)` is defined but the system feature is disabled, this test
        began failing after r274610. This is because the new image extraction deferral gesture now blocks text
        interaction gestures, but the code to actually fail this deferring gesture (and thus, "lift" the deferring
        gesture gate) is still behind the system flag. As a result, text interactions when the image extraction flag is
        disabled will only begin after the touch ends.

        This means that when selecting text via a long press, the text selection doesn't appear until lifting the touch
        if image extraction is disabled. To fix this, we only enable this deferring gesture in the case where the system
        feature is enabled.

        Shutdown ANGLE on GPU process when last WebGL context is destroyed
        https://bugs.webkit.org/show_bug.cgi?id=223082

        Reviewed by Kenneth Russell.

        Schedule a check for releasing the ANGLE default display when global
        count of remote graphics contexts reach zero. This should decrease the
        memory use of sessions where WebGL is not always on.

        Dispatch the check 0.2s after hitting zero, so that the optimization still
        affects page navigations but maybe does not redundantly deinitialize /
        reinitialize ANGLE in the cases where the context #1 is created and destroyed

        [iOS] WebPageProxy's EditorState may be stale until the next remote layer tree commit
        https://bugs.webkit.org/show_bug.cgi?id=223207
        <rdar://problem/75410700>

        Reviewed by Tim Horton.

        Fixes a race condition wherein it's possible for the cached `EditorState` in the UI process (on `WebPageProxy`)
        to be set to a stale (older) value after being set to a newer value. This can happen in the case where:

        1.  An editor state update is computed and set on a remote layer tree transaction in the web process, inside
            `WebPage::willCommitLayerTree`. A pending `BackingStoreFlusher` is created, and we dispatch a task onto a
            background queue to flush the layer tree commit.

        2.  IPC that updates the selection arrives in the web process (e.g. WebPage::selectTextWithGranularityAtPoint),
            and causes us to send an `EditorStateChanged` message to the UI process with this new selection.

        3.  The pending `BackingStoreFlusher` created in step (1) dispatches on the background queue, and sends its
            editor state over to the UI process.

        As a result, the UI process receives the `EditorStateChanged` message in step (2) before it receives the remote
        layer tree transaction sent in step (3), which contains the editor state computed prior to step (2); we then set
        `WebPageProxy::m_editorState` from its value computed in step (2) to the value computed in step (1).

        To fix this (and any similar issues involving out-of-band editor state updates), we introduce a monotonically
        increasing transaction ID on editor state that's similar to the one used for remote layer tree commits; we then
        avoid updating the editor state in `WebPageProxy` if we receive an `EditorState` whose transaction ID is less
        than our current ID.

        platform-agnostic, and move the platform-dependent logic previously implemented by individual `updateEditorState`

        WebGL IPC should use shared memory for synchronous messages
        https://bugs.webkit.org/show_bug.cgi?id=220974
        <rdar://problem/73876947>

        Reviewed by Geoffrey Garen.

        Send synchronous messages via the stream shared memory.
        Improves MotionMark on iMac1,1 from 5000 to ~5300 pts.

        If the message is encodable as a value, try to do so.
        If the reply is encodable as a value, try to do so.
        A message or a reply is not encodable if an argument in the message
        must be passed by reference via the OS specific mechanism
        (e.g. a iosurface or a file handle cannot be sent as a value).

        Similar to asynchronous messages, if the synchronous message fits to
        the stream buffer, the message is sent via the buffer. Same with the
        reply.

        If the message or reply is not sent via the stream buffer, it is sent via
        the normal IPC.

        The client protocol is:
        1) Write the message to the buffer and release it.
        2) Wait until the server releases the whole buffer back to the client.
        3) Read the reply from index 0.
        4) Continue sending next message from index 0.

        The server protocol is upon receiving a message that is synchronous:
        1) Read the message from the message position, dispatch it.
        2) Write the reply to index 0.
        3) Release the whole buffer back to the client.
        4) Continue reading next message from index 0.

        The client will not know at the send time whether the server will reply
        via the stream or via normal IPC message. The client will reserve
        a IPC sync request ID for normal IPC reply purposes.

        In case a message or a reply does not fit to the stream buffer, the
        ProcessOutOfStreamMessage message is written to the buffer instead.
        This will make the reader to wait for the normal IPC message.

        Changes temporarily so that the creation of the context waits for the
        confirmation that the creation was done. This is due to synchrononous
        stream send unable to deliver the WasCreated message during
        wait for reply, at the moment.

        Mark all asynchronous message sends with DispatchMessageEvenWhenWaitingForSyncReply.
        Otherwise synchronous messages will be dispatched before asynchronous messages.
        The messages are temporally dependent.

        Consider initial message exchange in canvas-blending-color-over-image.html:
        GPUConnectionToWebProcess_CreateRenderingBackend
        RemoteRenderingBackend_CreateImageBuffer
        RemoteRenderingBackend_DidCreateSharedDisplayListHandle

        RemoteRenderingBackend_GetDataURLForImageBuffer
        RemoteRenderingBackendProxy_DidCreateImageBufferBackend
        RemoteRenderingBackendProxy_DidCreateImageBufferBackend

        If GPU process is waiting for a sync reply when the sequence up
        until GetDataURL.. arrives, then the dispatch order is:

        GPUConnectionToWebProcess_CreateRenderingBackend
        RemoteRenderingBackend_GetDataURLForImageBuffer
         [... rest of the messages]

        This is a rare case, affects only the case where:
        1) These messages arrive before main thread processes the message queue
        2) GPU process has sent a synchronous message and is waiting for a reply

        In base case after RenderingBackend has been created and the work queue
        receive queue has been installed, all messages are moved to the work
        queue thread and dispatched in order of arrival.

        No new tests, timing dependent and WebKit code cannot be

        No new tests; a truly deterministic test would require a .cgi script to block loading after

        test to cover this behavior.

        The WebM TrackEntry "enabled" bit is optional, and WebKit previously waited until any media data
        was appended to say whether or not the track is enabled in the absense of an explicit signal.
        Instead, assume any track that is not explicity disabled is enabled, for the purpose of the
        format reader. This means that "enabled" queries will no longer block, which breaks the deadlock

        The part that this patch fixes is the "Web process also needs a call to CTFontManagerEnableAllUserFonts()
        and a sandbox extension to access fontd" under MobileAsset Fonts / Safari.

        From looking at this chart, it becomes clear that a new message is necessary that does:
        1. Adds a sandbox extension so the web process can access fontd
        2. Calls CTFontManagerEnableAllUserFonts() to cause platform font routines to use fontd

        So that's exactly what this patch does. It adds new WKWebView SPI,
        _switchFromStaticFontRegistryToUserFontRegistry, which does these two things.

        Even when we start using fontd, that doesn't allow user-installed fonts in WebKit in Safari, because we'll still
        continue to use kCTFontUserInstalledAttribute / kCTFontFallbackOptionAttribute, just like we do in Big Sur.

        Reviewed by Geoffrey Garen.

        Introduce WorkQueue::main() to get the main thread's work queue. This allows us to port some more code from
        dispatch_queue to WorkQueue. It also simplifies some code that has to deal that sometimes needs to run on
        the main thread and other times on a background queue. Having a single WorkQueue type to represent both the
        main thread and a background queue makes writing such code more convenient.

        r260302 was based on the faulty assumption that if we receive bytes from a server after a client certificate challenge,
        it must've accepted the client certificate we provided and we should always provide this certificate to this server.
        This assumption is faulty because there are servers that request a client certificate but provide a response if you do
        not provide a certificate that it accepts.  I'm removing this code because as part of my investigation of rdar://73974226
        I found that it did not help anything, and since then I committed r269162 which did help solve that problem.

        REGRESSION(r272469): [WPE][GTK] Epiphany UI process crashes when downloading PDFs, WebKitSecurityOrigin should use SecurityOriginData
        https://bugs.webkit.org/show_bug.cgi?id=222943

        Reviewed by Alex Christensen.

        Since r272469, WebCore::SecurityOrigin no longer accepts custom protocols except those
        registered with LegacySchemeRegistry. WebPage registers all custom protocols, but
        WebPageProxy does not, so WebCore::SecurityOrigin now only supports custom protocols in the
        web process, not the UI process. This causes Epiphany to crash when the protocol of its
        WebKitSecurityOrigin is unexpectedly NULL.

        Alex wants to reduce usage of WebCore::SecurityOrigin outside the web process, so instead of
        registering custom protocols with LegacySchemeRegistry in the UI process -- making it harder
        to eventually get rid of LegacySchemeRegistry -- we will transition WebKitSecurityOrigin
        from WebCore::SecurityOrigin to WebCore::SecurityOriginData, which is a simple data store
        for <protocol, host, port>. This is mostly sufficient to implement WebKitSecurityOrigin,
        except for webkit_security_origin_is_opaque(). I considered multiple ways to handle this,
        but ultimately decided to just deprecate it. Epiphany is the only client using this function
        in order to implement a WebKitSecurityOrigin equality operation, and it does so using
        origins that should never be opaque, so there are no compatibility concerns here.

        [GPU Process] Assertion under RenderLayerCompositor::computeCompositingRequirements()
        https://bugs.webkit.org/show_bug.cgi?id=220375

        Reviewed by Eric Carlson.

        When "GPU Process: Media" is enabled, `MediaPlayer` will call `mediaPlayerEngineUpdated()`
        three times when a media element tries to load a URL. The three calls happen at the
        following time points:
        1) `MediaPlayer` creates a `MediaPlayerPrivateRemote`.
        2) `MediaPlayerPrivateRemote` receives the response of a "createMediaPlayer" message
        from the GPU process and gets the initial configurations of the "remote" media player.
        3) The `RemoteMediaPlayerProxy` creates a `MediaPlayerPrivate` in the GPU process and
        notify the `MediaPlayerPrivateRemote` in the WebContent process.

        The second call of `mediaPlayerEngineUpdated()` is unnecessary because the player's
        configuration at that time is similar to `NullMediaPlayerPrivate`. This patch removes it.

        For the third call of `mediaPlayerEngineUpdated()`, we have to make sure that
        the `MediaPlayerPrivateRemote` has received the configuration update from the GPU
        process before the call. Therefore, this patch removes the message
        `MediaPlayerPrivateRemote::EngineUpdated`, and let `MediaPlayerPrivateRemote`
        decide when to call `mediaPlayerEngineUpdated()`.

        <rdar://problem/75013854>

        Reviewed by Alex Christensen.

        Add an additional property to _WKWebsiteDataStoreConfiguration to help thread the correct bundle
        ID of the driving application to lower levels of WebKit so that we can provide better messaging
        when a remote service (e.g., Safari View Controller or ASWebAuthenticationSession) is used. Currently
        we often lack context and have to report a generic "web content" message that doesn't help a user
        understand which app is actually requesting the load.

        We cannot use either of the existing bundle ID's for this purpose since we always indicate 'com.apple.Safari'
        as the source application to ensure proper handling of web traffic in lower levels of the system Network stack,
        and sourceApplicationSecondaryIdentifier is used for Apple Pay purposes and cannot be repurposed for this task.

        This first patch adds the property. A follow-up patch will flesh out the implementation.

        Logic for updating the text selection when dragging selection handles should account for image overlays
        https://bugs.webkit.org/show_bug.cgi?id=223010

        Reviewed by Tim Horton.

        Apply the same logic introduced in r272503 to iOS, when extending the selection by moving selection handles. In
        the case where the hit-tested node is the image overlay container (as opposed to any text inside the container),
        it's better avoid updating the selection, rather than extend the selection to the start of the image overlay.

        A user may deny an audio getUserMedia request.
        On user gesture, user may be reprompted, in which case user may grant access.
        Before the patch, after these two getUserMedia calls, if the web page was trying to call getUserMedia without user gesture, it would fail.
        With this patch, we remove the first denied request based on the second granted request.
        This allows getUserMedia to be granted, even without a user gesture.

        Reviewed by Geoff Garen.

        Because NetworkProcess::CreateNetworkConnectionToWebProcess is sent with SendOption::DispatchMessageEvenWhenWaitingForSyncReply, it is possible
        for two messages of type NetworkProcess::AddWebsiteDataStore and two messages of type NetworkProcess::CreateNetworkConnectionToWebProcess to be in the queue,
        but the second NetworkProcess::CreateNetworkConnectionToWebProcess jumps to the front of the line while the UI process is waiting for the reply to the first.
        Then, when calling NetworkProcess::swServerForSession we expect the session's parameters to have been initialized in the network process already, but we cut
        ahead of the parameter initialization message.  This is a realistically rare condition that can only be hit when using SPI, but it is hit in the
        ResourceLoadStatistics.StoreSuspension API test.  To fix this, we send the WebsiteDataStoreParameters from each WebsiteDataStore in the NetworkProcessCreationParameters.
        To avoid doing extra work, we introduce an early return in NetworkProcessProxy::addSession if we have already added parameters from this session to the network process.

           would avoid doing bad things when trying to remove a message receiver
           that's already been destroyed.

        Add a MESSAGE_CHECK() in WebProcessProxy::createSpeechRecognitionServer() to
        make sure the identifier is not already in the map. There used to be a debug
        assertion but we should MESSAGE_CHECK() too since the value is coming from
        IPC.

        WinCairo WebKit2 layout tests were observing deadlocks in
        WTF::Thread::ThreadHolder::~ThreadHolder while
        WebKitWebProcess.exe is shutting down in the IPC thread.
        WebProcess calls _exit in IPC threads if a IPC connection is
        disconnected.

        r260911 (Bug 210955) fixed a similar deadlock by skipping the
        destruction in ~ThreadHolder if the calling thread is the main
        thread.

        Microsoft Docs describe how a process is terminated and recommend
        TerminateProcess API to avoid such deadlocks.

        Adopt new NSURLSessionConfiguration SPI for connection cache configuration
        https://bugs.webkit.org/show_bug.cgi?id=222934

        Reviewed by Geoffrey Garen.

        This uses the NSURLSessionConfiguration connection cache limit SPI introduced in Big Sur to
        properly set the parameters we want for HTTP/1.1 connections. Previously we tried to do this
        using _CFNetworkHTTPConnectionCacheSetLimit in NetworkProcessCocoa, but this didn't work
        because that SPI only applies to NSURLConnection rather than NSURLSession.

        In particular, this meant that the number of priority levels wasn't set correctly, which we
        had to work around by constraining the number of priority levels when mapping WebKit
        resource priorities to CFNetwork priorities (https://bugs.webkit.org/show_bug.cgi?id=203423).
        This patch adopts the SPI and removes that workaround.

        In Bug 222145 I converted serialization of CFURLRequest to NSURLRequest. As part of that change,
        I used a new encoder (WKSecureCodingURLWrapper) to wrap the NSURL to ensure proper handling of
        encoded URLs.

        The WKSecureCodingURLWrapper should have been declared as a subclass of NSURL, so that NSSecureCoding
        would respect it as a valid way of serializing an NSURL.

        WebGL asserts after GPU process times out
        https://bugs.webkit.org/show_bug.cgi?id=222546

        Reviewed by Wenson Hsieh.

        IPC::StreamClientConnection::tryAcquire would assert on
            ASSERT(untrustedLimit < (dataSize() - 1));
        The untrustedLimit value would be then:
            StreamConnectionBuffer::serverOffsetClientIsWaitingTag.
        This would be equivalent of assertion added in this commit:
            ASSERT(clientLimit != ClientLimit::clientIsWaitingTag);

        This would happen in case of timeout, because upon entering
        the wait sequence:
         1) The client itself would first write the tag value to the
            offset variable.
         2) Wait and timeout the wait.
         3) run the next iteration of the acquire loop.

        The next iteration would load the tag value written before,
        e.g. serverOffsetClientIsWaitingTag.
        This would be then used in clampedLimit() call.

        Fix this by taking it into account that the variable might be
        ClientLimit::clientIsWaitingTag within the acquire loop.

        Possibly fix future similar problems by not treating the value as
        size_t, rather treat it as enum class ClientOffset : size_t. This
        enables the compiler to enforce that when checking for the various tag
        values, the holder must hold the enum class. When intending to interpret
        the value as size_t, holder must explicitly convert.

        Do the above change for the ServerOffset.

        Remove `SuppressInteractionToken`, along with its only use as a member on `WKContentView`. This was used to
        temporarily suppress the image extraction interaction when editing, but is now no longer necessary, since we're
        removing all dependence on this interaction object.

        There's no need to cancel the regular text interaction in favor of the image extraction interaction after this
        patch, since the former will be used for both. However, we do need to temporarily suppress regular text
        interaction while image extraction is still pending, to avoid prematurely selecting the entire image element.

        To do this, we keep track of the element pending image extraction (`_elementPendingImageExtraction`), and avoid
        allowing text interactions to begin if we're over this exact element.

        (-[WKContentView _singleTapIdentified:]):

        We don't need to explicitly cancel the image extraction interaction on single tap anymore; this behavior will
        automatically fall out of using default text interactions for image extraction.

        Remove explicit image extraction cancellation here as well, and instead bail from the drag only if we're about

        (WebKit::WebPage::positionInformation):

        Allow text interactions to begin in user-agent shadow roots. This matches behavior on macOS, and was
        (presumably) initially disallowed on iOS to avoid activating the editable text interaction
        (`UIWKTextInteractionAssistant`), as opposed to block text selection interactions, when long pressing text
        inside textareas and text fields. However, since we only use the normal text interaction assistant now for both
        non-editable and editable text, this distinction no longer matters.

        Update ApplicationCacheStorage::originsWithCache() to return a HashSet<SecurityOriginData> instead of a Vector<Ref<SecurityOrigin>>.
        Using a HashSet makes sure we do not return duplicates (which do occur as per ApplicationCacheStorage implementation) and makes typing
        more consistent with other similar storage functions. Using SecurityOriginData is more lightweight and sufficient for our use cases.
        It also takes care of a FIXME comment in WebsiteDataStore::fetchDataAndApply about switching to SecurityOriginData.

        This patch also updates WebsiteDataStore::fetchDataAndApply() to crossThreadCopy() the securityOriginData before sending them from
        the data store queue to the main thread. The previous code as sending SecurityOrigins and WebsiteData to the main thread without
        any isolated copy, which was fragile and would not have been thread-safe if ApplicationCacheStorage::originsWithCache() had cached
        the origins it returned for example.

        Also update WebsiteDataStore::removeData() to make sure we crossThreadCopy() the origins before sending them from the main thread

        Update HTMLMediaElement::originsInMediaCache() to return SecurityOriginData instead of SecurityOrigin objects
        https://bugs.webkit.org/show_bug.cgi?id=222820

        Reviewed by Darin Adler.

        Update HTMLMediaElement::originsInMediaCache() to return SecurityOriginData instead of SecurityOrigin
        objects. The caller only needs SecurityOriginData objects and there was a FIXME comment about switching
        to SecurityOriginData. SecurityOriginData is beneficial here because it is a smaller object and it
        can be easily passed over IPC.

        Also update the code at WebsiteDataStore::fetchDataAndApply() to crossThreadCopy() the originDatas
        before sending them to the main thread. The previous code was passing both the SecurityOrigins
        and the WebsiteDatas from the data store queue to the main thread without isolated copy, which was
        fragile. For example, if HTMLMediaElement::originsInMediaCache() was caching the security origins
        it returned, the code would not have been thread safe.

        Use WTF::DestructionThread::MainRunLoop for CallbackAggregators in WebsiteDataStore
        https://bugs.webkit.org/show_bug.cgi?id=222831

        Reviewed by Geoffrey Garen.

        Use WTF::DestructionThread::MainRunLoop for CallbackAggregators in WebsiteDataStore to make sure
        the CallbackAggregators get destroyed on the main thread. Previously, the code was letting the
        CallbackAggregators get destroyed on any thread and then dispatching to the main thread in their
        destructor their WebsiteDataStore data member to make sure it gets destroyed on the main thread.

        It is simpler and safer to have the CallbackAggregators get destroyed on the main thread.

        Also add threading assertions whenever the pendingCallbacks is used since this counter is not
        atomic.

        Reviewed by Geoffrey Garen.

        The previous code was passing SecurityOriginData objects from the data store queue to the main
        thread without isolated copy. This code would not be thread-safe if the function we got the
        origins from would keep a copy of the origins (e.g. caching). To make this more robust from a
        thread-safety standpoint, we now crossThreadCopy() to origins before passing them to the main
        thread.

        I also updated these to construct the WebsiteData on the data store queue instead of the main
        thread for consistency with other cases inside WebsiteDataStore::fetchDataAndApply().

        [GTK] Clean up GTK-specific text checker stuff
        https://bugs.webkit.org/show_bug.cgi?id=222818

        Reviewed by Don Olmstead.

        This moves the GTK-specific classes WebTextChecker and WebTextCheckerClient into
        GTK-specific directories.

        This also moves most of WKTextChecker, except for WKTextCheckerSetTestingMode, which is
        cross-platform. This is not quite how we normally do it -- normally we try to have one
        cross-platform header with platform-specific conditionals and only separate out platform-
        specific source files -- but in this case the header is almost entirely GTK-specific, so it
        makes sense to do it this way.

        This also exposes WKTextCheckerSetContinuousSpellCheckingEnabled and uses it in
        UIScriptControllerGtk, which is needed for bug #181916.

        This code is all pretty messy, especially the WKTextCheckerClient (which actually has its
        own WKTextCheckerSetContinuousSpellCheckingEnabled!), but now it's a *platform-specific*
        mess, which is a small improvement.

        - If preference is AppleLanguages, set it for the volatile domain to match what we do in XPCServiceMain.mm.
          This is needed because the preference in the volatile domain seems to take precedence.

        Reviewed by Simon Fraser.

        Replace use of IOSurfaceSetOwnership() SPI with IOSurfaceSetOwnershipIdentity().
        Both do the same thing but IOSurfaceSetOwnershipIdentity() only requires an identity token
        for the new owner (instead of a control port). As a result, IOSurfaceSetOwnershipIdentity()
        requires a lot less priviledges and can now be used directly in the GPUProcess instead of
        the WebProcess.

        WebKit2 has long had an unusual way of softlinking PDFKit, using NSBundle.
        It has caused much trouble in the past, because it means that running
        WebKit against a custom PDFKit requires either installing it into
        the system, or changing the hardcoded path.

        Instead of this, just use the normal softlinking macros that the rest

        The issue was that when WebProcessProxy::requestTermination() was called (e.g. process is killed by WebKit
        for using too much memory), we would fail to remove the process from the WebProcessCache. Because the
        terminated would stay in the cache (even though WebProcessProxy::shutDown() was called), we could potentially
        try and use it later on for a navigation to the same domain. This would lead to crashes because
        WebProcessProxy::shutDown() has already been called.

        Note that we were previously correctly removing the process from the cache in case of a proper crash, inside
        WebProcessProxy::processDidTerminateOrFailedToLaunch(). I have moved the logic to remove from the cache
        from processDidTerminateOrFailedToLaunch() to shutDown() to avoid similar issues in the future.

        [GPUP] Replace references to GPUProcessConnection and Connection with WeakPtr<GPUProcessConnection>

        As we did in r273473, this patch replaces some references to `GPUProcessConnection` and `Connection`
        with `WeakPtr<GPUProcessConnection>`. r273473 was for the GPU process, this patch is for web processes.
        When the GPU process crashes, the `GPUProcessConnection` object (as well as its `Connection` object)
        will be destroyed, and the reference will be invalid.

        Web Inspector: give WebInspectorUIExtensionControllerProxy a chance to teardown when the frontend is about to close

        ensures that the full set of NSURLRequest features are accurately reconstituted on the

        [Cocoa] Web Inspector: add support for receiving Web Extension events via _WKInspectorExtensionDelegate

        <rdar://problem/71206685>

        Reviewed by Devin Rousso.

        This patch adds support for clients to receive extension lifecycle events. For now this includes
        extension tab shown/hidden, but will eventually include page navigations and other events exposed
        via Web Extensions API.

        This is implemented at the WebKit level via new InspectorFrontendClient methods. This gets piped to
        WebInspectorUIExtensionControllerProxy via IPC, which then passes on the event to _WKInspectorExtensionDelegate.

        _WKInspectorExtensionDelegate is a delegate of _WKInspectorExtension. It's for receiving lifecycle events, and
        is implemented similarly to _WKInspectorDelegate. WebInspectorUIExtensionControllerProxy now keeps a map of
        extension API objects so that it can call out to the the appropriate extension API object's client/delegate.

        To better handle the situation where client completion handlers may be invoked after the inspector page has been torn down,
        switch WebInspectorUIExtensionControllerProxy to be RefCounted instead of std::unique_ptr so that the appropriate
        API object can be retrieved in the async IPC reply block. (IPC message receiver code knows how to ref the receiver
        if it expects to deliver a response).

        Lastly, since this patch introduces InspectorExtensionError at the WebCore level, I decided to move the contents
        of InspectorExtensionTypes.h to the Inspector namespace. It made more sense than typing out WebCore::InspectorExtensionError
        and the like. As part of this change, the string type aliases Inspector::ExtensionID and Inspector:ExtensionTabID are
        now defined in InspectorFrontendClient.h.

        Tested by existing layout and WebKitAPI tests.

        Revise IPC serialization so that NSURLConnection (modern) Cocoa builds serialize the
        NSURLRequest object, rather than bridging to CFURLRequest and serializing that. This
        ensures that the full set of NSURLRequest features are accurately reconstituted on the
        receiving side of the connection.

        Because NSURL serialization doesn't handle some encoded parameters properly, we implement
        an archiving delegate to archive the URL like we do for CFURL.

        [GPUP] Use a WeakPtr of GPUConnectionToWebProcess instead of a reference in some media related objects

        Reviewed by Eric Carlson.

        A GPUConnectionToWebProcess object may be destroyed when we close a page, then crash will happen
        in callbacks accessing the GPUConnectionToWebProcess object. For example, in

        replaces the references to a GPUConnectionToWebProcess with WeakPtr(s) in places where the

        Add a null check for the hit test result's `targetNode` inside `rangeForPointInRootViewCoordinates()` to avoid

        Additionally, avoid a potential null deref on `selectionStart.deepEquivalent().anchorNode()` and
        `selectionEnd.deepEquivalent().anchorNode()` by using `Position::treeScope()` (which null checks the anchor
        node) instead of directly asking the anchor node.

        [iOS] Add a watchdog timer to forcibly reset deferring gesture recognizers
        https://bugs.webkit.org/show_bug.cgi?id=222216

        Reviewed by Simon Fraser.

        Add a mechanism to detect and resolve situations where at least one deferring gesture recognizer
        (`WKDeferringGestureRecognizer`) is stuck in Possible state after ending touches, but the touch event gesture
        recognizer is unable to be reset (i.e. neither possible or recognizing). This state is indicative of a general
        class of bugs regarding native gesture deferral, wherein our "gesture gates" never end up being lifted after
        ending all touches in the view. One such example of this type of bug was fixed in r272584, where all interaction
        (touch events, scrolling, tapping) due to the touch end deferrers never exiting Possible state after long
        pressing to present a context menu.

        To make these kinds of bugs both easier to diagnose and less fatal in the future, we introduce a watchdog timer
        that dispatches after ending all touches on the content view, and checks the consistency of deferring gesture
        recognizers in the view; if we detect stuck deferring gestures, we handle this by forcibly resetting the stuck
        deferring gestures and logging a fault message.

        I manually verified this change by reverting my fix for the aforementioned bug (r272584), and observing both (1)
        a system log fault message, and (2) that interactions continued to work even without the fix in r272584, after
        the watchdog timer fired. See below for more details.

        Add a helper class that wraps a `RunLoop::Timer` for the main runloop, and schedules a 1 second timer after all
        deferring gestures have ended; assuming no new touches begin after this timer is scheduled, we'll perform a
        consistency check over the content view's gestures and perform a log fault and force deferring gestures to end
        if needed.

        HTMLCanvasElement::copiedImage() contains old image with GPU Process on
        https://bugs.webkit.org/show_bug.cgi?id=222101

        Reviewed by Simon Fraser.

        Implement RemoteImageBufferProxy::copyImage and
        RemoteImageBufferProxy::copyNativeImage.
        Implement by asking the data from the GPU process.

        Previously, with AcceleratedImageBufferShareableMappedBackend
        the HTMLCanvasElement::copiedImage() would construct the copy
        by copying the CGContext backed by the IOSurface that is accessible
        by both processes. This would succeed. After a draw to the image,
        the second copy would not reflect the draw but contain the same
        image as the first copy.

        Fix by not using the fact that the IOSurface is accessible by both
        processes. In the end, IOSurfaces will not be available in
        Web process.

        Converts NativeImage to ShareableBitmap with WebCore::CompositeOperator::Copy
        since the ImageBuffers might have unpremultiplied contents. Also, ShareableBitmap
        does not have contents, so blending is overhead.

        No new tests, enables ~150 tests.

        Prepare for memory ownership transfer in the GPUProcess
        https://bugs.webkit.org/show_bug.cgi?id=222122

        Reviewed by Simon Fraser.

        Prepare for memory ownership transfer in the GPUProcess:
        1. Have the WebProcess create a task identity token and pass it to the GPUProcess
           when connecting to it. The WebProcess' task identity token is then stored on
           the GPUConnectionToWebProcess object.
        2. Add the entitlement to the GPUProcess that is needed to transfer memory ownership
           to another process.

        This is a first step towards having the GPUProcess transfer memory ownership of its
        IOSurfaces and Metal textures to the WebProcesses it is serving.

        When a WebKit client provides a user directory suffix in the process initialization parameters, confstr with the new
        user suffix applied will fail to create the full directory path if it does not exist, and return an empty result.
        This will lead to empty paths in the sandbox parameters, which will cause the sandbox to fail to compile, which will
        eventually crash the WebKit process. This patch addresses this by making sure the new user directory suffix does not
        represent a path, since confstr is not able to handle user directory suffixes containing paths that do not exist.
        Additionally, this patch reverts r271417, which was the first attempt at fixing this crash, but was unsuccessful in
        doing so.

        WebGL GPU process IPC should use shared memory for asynchronous messages
        https://bugs.webkit.org/show_bug.cgi?id=219641
        <rdar://problem/72340651>

        Reviewed by Geoff Garen.

        Implement a concept of a message buffer. This is a similar concept as
        "command buffer" or "display list" in some graphics APIs. Messages
        can be added to the buffer by a client and then played back by a
        server.

        Current implementation adds a specific pseudo-infinite,
        semi-duplex message buffer type IPC::StreamConnectionBuffer. This
        is a buffer that can be attached to stream connection, an object
        that can deliver IPC messages either through the message buffer
        or through normal IPC::Connection. The stream connection is
        implemented as IPC::StreamClientConnection and IPC::StreamServerConnection.
        The connection has server and client distinction, similar to
        IPC::Connection. Unlike IPC::Connection, a stream connection is asymmetric
        in features: the client can send messages and receive replies, where
        as the server can receive messages and send replies.

        Messages received through IPC::StreamServerConnection can be
        processed by StreamConnectionWorkQueue.

        Currently asynchronous messages are added to the stream. Synchronous messages
        and their replies are dispatched through normal IPC.

        WebGL is implemented by having one StreamConnectionWorkQueue for all WebGL
        in the browser. Currently each web process WebGL context in has one
        StreamClientConnection attached to one 2mb StreamConnectionBuffer.

        Later on, there will be only one WebGL stream connection and connection
        buffer shared between all contexts in particular thread in Web process.
        The implementation is "optimized" for the later on case. Due to single-
        process nature of each page, it does not make much sense to have buffer
        per context. However, it is anticipated that many of the successive calls
        are to same context. The SHM message format implements an optimization
        where the destination id is maintained as part of the stream connection
        state.

        In GPU process side, all WebGL is processed in one task queue,
        "RemoteGraphicsContextGL task queue". It will process up to 1000 commands
        per connection per iteration.

        Implemented as follows:
        Sender shares the shared memory area with the destination when creating
        the destination.

        If the message fits to the stream shared memory area, write it there.
        Otherwise send it via normal IPC as out of line message.

        Messages to the destination arrive as before, in order. For each out of line
        message, an entry is pushed to the stream. Receiver will stop processing the
        stream and processing will continue once the out-of-line
        message has been processed.

        Sender can write messages to the stream simultaneous to the receiver reading
        the messages. This is implemented as a ring buffer with atomic sender and receiver
        pointers.

        Stream connection processing is implemented as a shared semaphore. This semaphore
        is notified if the receiver is waiting on it.

        Performance impact (iMac Pro):
            - MotionMark triangles: 300 points -> 4000 points
              (~7000 points no-GPUP)
            - WebGL samples Aquarium: 1000 fish ~60fps -> 5000 fish ~60fps
              (~5000 fish with no-GPUP)

        Due to the selection of how the size is marked up, the
        common implementation does not contain all the non-trivial code.
        The "algorithm" uses a "hole indicator" to differentiate between

        We are sometimes crashing under Decoder's copyBuffer(), inside the memcpy()
        call, with a null address. I have no idea how this is happening and this
        code has not changed in a long time so I have made the following hardening:
        1. Update copyBuffer() to use tryFastMalloc() instead of fastMalloc(). Log
           and return null if tryFastMalloc() failed instead of calling memcpy().
        2. Update Decoder::create() to log and return early if the input buffer
           is null.
        3. Update Connection's createMessageDecoder() to use CheckedSize when
           computing the bodySize that is being passed to Decoder::create(). If
           we overflow, log and return null.

        No new tests, no idea how this can happen in practice.

        Norton Safe Web extension is causing crashes / hangs under [WKRemoteObjectEncoder encodeObject:forKey:]
        https://bugs.webkit.org/show_bug.cgi?id=222172

        Reviewed by Alex Christensen.

        The extension appears to be trying to send a JSValue that is a DOM Node. WebKit makes the following
        call to convert it into a NSDictionary:
        `[[JSValue valueWithJSValueRef:value inContext:[JSContext contextWithJSGlobalContextRef:JSContextGetGlobalContext(context)]] toObject]`

        JSC very aggressively iterates over all of the properties of the DOM Node and recursively ends up
        converting the whole DOM tree with all their properties. This leads to a lot of cycles to as JSC
        maintains the JSObject <-> NSObject identity during the conversion (Each time the JSDocument is
        serialized, the same NSDictionary* pointer is used to represent it).

        The logic introduced in r270559 to detect cycles was flawed because it relied on a NSSet of
        NSObject* and [NSSet containsObject:] to detect the cycles. The issue is that [NSSet containsObject:]
        doesn't do a simple pointer comparison but instead calls [NSObject isEqual:] which is very
        expensive for types like NSDictionary and leads to trouble when the dictionary contains a cycle.
        To address this I replaced the NSSet with a WTF::HashSet<NSObject *> so that key lookup ends up
        doing a simple pointer comparison.

        Even after the previous fix, the extension would still cause massive hangs because it would take
        a very long time to try and encode the whole DOM tree with all the properties of each Node (even
        without cycles). To address this, we now abort encoding when detecting a cycle instead of encoding
        an empty object to break the cycle.

        After this change, Safari becomes usable with this extension again. However, there are still much
        shorter hangs that occur due to the converting of the JSNode into a JSDictionary via
        [JSValue toObject]. We should probably improve this in a follow-up.

        Easy way to reproduce the crash / hang:
        1. Install Norton Safe Web & Norton Password Manager extension (may require a subscription)
        2. Make sure the extensions are activated and turned on by clicking on their icons next to the
           URL bar
        3. Go to https://bugs.webkit.org/attachment.cgi?id=420530&action=edit
        4. Click on the combo box next to "Review" -> Hang / Crash

        The class calls Connection::addWorkQueueMessageReceiver() during its

        The virtual function pointer is not fully constructed during the call time.
        Connection may start dispatching calls to the work queue. The work queue may
        dispatch the task function through that pointer immediately after the call. If a
        message comes during the constructor call, it may be dispatched during the
        constructor still running, before the virtual function pointer being correctly
        set up. Accessing virtual function pointer is not thread safe until it is fully

        the migration happens only once each time we update the schema, this

        [WPE] User-Agent quirks not implemented
        https://bugs.webkit.org/show_bug.cgi?id=222109

        Reviewed by Carlos Garcia Campos.

        Have WPE benefit from GTK's existing user agent code by moving the bits in WebPageGtk.cpp
        and WebPageProxyGtk.cpp to WebPageGLib.cpp and a new WebPageProxyGLib.cpp. This also moves
        over a few stub functions that are unimplemented in both WPE and GTK. Finally, it moves a
        WebsiteDataStore function that had gotten very lost.

        No new tests. Unfortunately, our existing user agent quirks tests do not exercise these
        higher-level functions, and so were already running and passing for WPE.

        These additions are necessary for clients to inject Web Extensions API into the tabs created
        using _WKInspectorExtension.

        Currently, Web Inspector pages use a private process pool that is separate from page content.
        Since there is no way to set the pool's injected bundle path prior to opening Web Inspector,
        we need to allow clients to explicitly configure and set a process pool to be used for
        WebInspectorUI and any iframe tabs created using _WKInspectorExtension.

        While currently unused inside `WebPasteboardProxy`, the next patch will attempt to use these page identifiers to
        retrieve a data owner type from the corresponding `WebPageProxy`, and then forward this data owner type to the
        `PlatformPasteboard`.

        This patch makes PrivateClickMeasurementManager::storeUnattributed() look
        for incoming source nonces and if found, call the new function
        PrivateClickMeasurementManager::getSignedUnlinkableToken().

        A new static function generateNetworkResourceLoadParameters() was added
        to reuse code between PrivateClickMeasurementManager::getSignedUnlinkableToken()
        and the existing PrivateClickMeasurementManager::fireConversionRequest().

        [WPE][GTK] Avoid another child setup function in process launcher code
        https://bugs.webkit.org/show_bug.cgi?id=222049

        Reviewed by Carlos Garcia Campos.

        Avoiding child setup functions is desirable because it could allow GSubprocess to use
        posix_spawn() instead of fork() in the future. That's not possible to do if we have code
        that needs to run between fork() and exec().

        In this case, the child setup is used only to unset CLOEXEC. We could simply not set it in
        the first place. This only fails if a secondary thread decides to launch a subprocess before
        XDGDBusProxyLauncher::launch returns. That window already exists in many other places (e.g.
        anywhere else setCloseOnExec is called, such as for IPC::Connection objects). Threads should
        not do that.

        This also fixes a bug where unsetting CLOEXEC would fail if we get unlucky and receive
        EINTR. A loop is required here. WTF::setCloseOnExec handles that for us.

        Add SPI for getting size of PDF document during printing

        <rdar://problem/74370891>

        Reviewed by Geoff Garen and Tim Horton.

        When printing a PDF, we want to know its page size.  If the print is initiated by the web process (such as when window.print is called
        or if the PDF contains JavaScript that tells the browser to print it) then we would like that information with the print request so we
        don't have to ask the web process, which is hung waiting for a synchronous message reply.  If the print is initiated by the UI process
        (such as if the user prints from a menu or keyboard shortcut) then we need a way to ask what the size of a PDF is.

        I reused the SPI in WKUIDelegatePrivate because it was only briefly adopted before we knew we needed this and then reverted.
        I'm also adding an SPI way to get from a WKPageRef to a WKWebView so this can be adopted without redoing all of Safari.

        ThreadMessageReceiverRefCounted subclasses are accessed in non-thread-safe way
        https://bugs.webkit.org/show_bug.cgi?id=221891

        Reviewed by Chris Dumez.

        For each ThreadMessageReceiverRefCounted subclass, remove calls
        to Connection::addThreadMessageReceiver() from the constructor.
        The calls pass 'this' as the ThreadMessageReceiver*. If the
        connection tries to dispatch a message during the constructor, this
        results in some or all of below:
        - non-thread-safe read of mutated virtual function pointer
        - call to incorrect member function, mostly to MessageReceiver::didReceiveMessage
        - an assert from above
        - skipped message

        For each ThreadMessageReceiverRefCounted subclass, remove calls
        to Connection::removeThreadMessageReceiver() from the destructor.
        The message receive destination is still active during destructor,
        so Connection might dispatch new message tasks during that time.
        This causes ref of the instance already being destroyed, which
        then causes the tasks to use deleted instance and then later
        deleting it again.

        Does not try to fix any other potential thread-related issues in
        the modified areas.

        [iOS][FCR] Add new datalist dropdown for text inputs
        https://bugs.webkit.org/show_bug.cgi?id=222008
        <rdar://problem/74410513>

        Reviewed by Wenson Hsieh.

        The new datalist dropdown appears as a popover on both iPhones and iPads.
        Previously, iPhones displayed a UIPickerView when tapping on the datalist
        button, while iPads displayed a popover. Furthermore, the datalist button
        was only visible after focusing the field. Now, the button can be used at
        any time.

        If the dropdown is presented while the software keyboard is visible, the
        keyboard will be dismissed to create space for the dropdown. On devices
        with a hardware keyboard, the dropdown is updated as characters are typed.

        Since r272636 it's no longer possible to differentiate between async reply being cancelled or data just being
        empty for WebPageProxy data completion handlers. Use Optional to indicate that the reply was canlled when its
        data is nullopt, and ensure we always provide a valid API::Data object when data is not nullopt.

        Regression(r268097): Calling processDidTerminate delegate asynchronously is risky compatibility-wise
        https://bugs.webkit.org/show_bug.cgi?id=222011

        Reviewed by Carlos Garcia Campos.

        Calling processDidTerminate delegate asynchronously like we did in r268097 is risky compatibility-wise.
        This caused breakage in at least 2 client applications. While this can be dealt with on the client side,
        it would be better to fix what r268097 was trying to fix without making the delegate call asynchronous.
        The reason calling the delegate asynchronously is risky is because some view state may have time to get
        reset by the time the client gets notified on the crash, potentially confusing the crash handling logic
        in the client.

        No new tests, covered by WKNavigation.ReloadRelatedViewsInProcessDidTerminate API test that is
        still passing even though the delegate call is no longer asynchronous.

        There was a logic error introduced into the new delegate situation after
        moving _WKInspectorDelegate from WKWebView to _WKInspector. When setting
        .delegate to nil, we shouldn't allocate dummy API::InspectorClient/
        InspectorDelegate instances. As written, these instances form their own retain
        cycle and cause a leak if Web Inspector has been opened or if
        WKWebView._inspector is accessed (which lazily creates the delegates).

        and set the WebInspectorProxy's client to nullptr.

        A few fixes that came from API review:

        1) Change closeAllMediaPresentations to be
        closeAllMediaPresentationsWithCompletionHandler. Ditto for
        pauseAllMediaPlayback and requestMediaPlaybackState. This leads to
        better Swift imports.

        2) Combine suspendAllMediaPlayback and resumeAllMediaPlayback into a
        single setAllMediaPlaybackSuspended:completionHandler function which
        takes a boolean. This reinforces the relationship between
        suspend/resume and differentiates them from pause.

        And a few other drive-by fixes, like moving WKMediaPlaybackState to
        the WKWebView class because it is unlikely to be used outside of that
        context, changing NSUInteger -> NSInteger, and changing the ordering
        of the WKMediaPlaybackState enum to be more natural.

        Add IPC::MessageReceiveQueue, an interface which obtains messages from
        the message receive thread and forwards them to caller as data.
        This is important in order to be able to skip messages that are stale
        or originating from a sender which is incorrect. Before, the client
        could only get the messages as Function references, and those cannot
        be skipped as it would be undefined what not executing a function means.

        IPC::MessageReceiveQueue is a generalization and simplification of current
        IPC::Connection::ThreadMessageReceiverRefCounted and
        IPC::Connection::WorkQueueMessageReceiver. It has different ref-count
        semantics, in the way that client controls the life-time with add and
        remove.

        IPC::MessageReceiveQueue fixes message reordering bug with

        Other subclasses call add...() correctly.

        This method of getting the app ID might seem like a strange contortion, but it's really

        Reviewed by Carlos Garcia Campos.

        GTK port is still supporting non-AC mode in WebKit2, and it can
        enable/disable accelerated compositing dynamically.

        r271235 fixed the bug that wheel event scrolling didn't work in
        non-AC mode pages by checking if EventDispatcher's
        m_scrollingTrees has a scrolling tree for a WebKit::WebPage.
        However, if accelerated compositing is disabled dynamically,
        m_scrollingTrees keeps to have a scrolling tree for the WebPage.
        m_scrollingTrees should remove the item if accelerated compositing
        is disabled.

        r271235 added a code to check m_scrollingTrees, but it didn't lock
        m_scrollingTreesMutex. The code can be removed. Removed it by
        moving to above code.

        EventDispatcher::wheelEvent was using a local lambda expression.

        [WPE][GTK] BubblewrapLauncher should create flatpak-info keyfile only once
        https://bugs.webkit.org/show_bug.cgi?id=221224

        Reviewed by Adrian Perez de Castro.

        BubblewrapLauncher should create its flatpak-info keyfile only once, because its contents
        will never change. Makes more sense to cache this tiny string in memory than to recompute it
        every time a subprocess is launched.

        When working on this, I noticed a quirk in the documentation of g_key_file_to_data: although
        the function has a GError parameter, it is legacy and the function is actually guaranteed to
        succeed. So icky though it seems, I've removed the error checking for that, as recommended
        by its documentation.

        Make RemoteRealtimeVideoSource a RealtimeVideoCaptureSource
        https://bugs.webkit.org/show_bug.cgi?id=221747

        Reviewed by Eric Carlson.

        All capture video sources are now deriving from RealtimeVideoCaptureSource.
        This allows to expose a RealtimeVideoSource that can handle changes of resolution and frame rate in software as needed.
        This also allows to better align audio and video sources on iOS: there will only be one running source at any given time.
        Covered by existing tests.

        PCM: Expired reports get sent at the same time after a session restart
        https://bugs.webkit.org/show_bug.cgi?id=221555
        <rdar://problem/73724816>

        Reviewed by John Wilander.

        Since PCM data is now persisted, we need to address the case of a
        session-restart after 24-48+ hours. We should not send all overdue
        attributions in the same burst in case multiple have the same destination
        and could identify a user cross-site.

        This patch kicks off the timer to fire pending attributions on session-start
        and sends one report at a time. If more than one overdue report exists
        at any time, we schedule the timer for a random interval between 15 and
        30 minutes.

        In theory this could result in some attributions never being sent if a
        user keeps quitting and restarting a session. In practice this is
        probably unlikely. Protecting the user's privacy is a hard requirement,
        so we think possible starvation of some reports is the right tradeoff.

        [watchOS] Adopt PUICQuickboardController for text input
        https://bugs.webkit.org/show_bug.cgi?id=221649

        Reviewed by Tim Horton.

        Refactor text input on watchOS to use `PUICQuickboardController`, instead of custom WebKit subclasses of
        `PUICQuickboardListViewController`. This new API serves the same purpose as the current list view controller
        subclass, by providing a view that offers options to dictate, scribble, and choose text suggestions. See below
        for more details.

        For the time being, this new `PUICQuickboardController` doesn't provide a way to render a custom header view
        for us to show the domain name; to avoid introducing a security or privacy bug in the interim, guard this behind
        a WebKit-exposed runtime-enabled setting that's off by default. We can remove this setting and instead just use
        the `HAVE(QUICKBOARD_CONTROLLER)` build-time flag once support for the custom header view is complete.

        * Platform/spi/watchos/PepperUICoreSPI.h:

        Include a couple of new headers if `HAVE(QUICKBOARD_CONTROLLER)` is set.

        * UIProcess/ios/WKContentViewInteraction.h:

        Add a `_presentedQuickboardController` instance variable if `HAVE(QUICKBOARD_CONTROLLER)` is set.

        * UIProcess/ios/WKContentViewInteraction.mm:

        Add protocol conformance to `PUICQuickboardControllerDelegate`.

        (-[WKContentView _updateInteractionTintColor:]):
        (-[WKContentView tintColorDidChange]):

        Refactor this to take `UITextInputTraits`, instead of using `_traits`.

        (-[WKContentView textInputTraits]):
        (-[WKContentView _updateTextInputTraits:]):

        Refactor this to modify the given set of text input traits given current focused element information state,
        rather than operating on the `_traits` instance variable. This refactoring allows us to share logic when setting
        up text input traits on both iOS and watchOS; in the former case, we're setting up a set of cached `_traits` on
        the content view, but in the latter case, we're modifying a newly created `PUICTextInputContext` that we'll then
        set on the `PUICQuickboardController`.

        (-[WKContentView _createQuickboardController:]):

        Add a helper method to create and return a new `PUICQuickboardController` that's suitable for the current
        focused element's state.

        (-[WKContentView presentViewControllerForCurrentFocusedElement]):

        Present the view controller for the focused element, by either using a custom WebKit-owned
        `PUICQuickboardListViewController` subclass, or by using a new `PUICQuickboardController` with a custom text
        input context. Note that in the latter case, we may not be able to invoke the UI delegate hook
        `-_webView:didPresentFocusedElementViewController:`, since the presenting view controller's transition
        coordinator may not have been created yet in the scenario where we're spinning up the Quickboard view service
        for the first time, since the call to establish the XPC connection is asynchronous in PepperUICore, and we don't
        attempt to present the remote view controller until the connection is established. This makes it so that we
        can't rely on the `-didPresentFocusedElementViewController:` hook in WebKitTestRunner to know when a
        `PUICQuickboardController` has finished presenting.

        To work around this, we teach the test harness to override `-presentViewController:animated:completion:` and
        call into the test runner's `WKWebView` subclass when a remote quickboard controller is done presenting. In the
        longer term, we will require SPI from PepperUICore to present a `PUICQuickboardController` with a completion
        block.

        (-[WKContentView _isPresentingFullScreenInputView]):

        A "full screen input view" for the focused element is now present if either `_presentedQuickboardController` is
        set, or `_presentedFullScreenInputViewController` is set.

        (-[WKContentView dismissAllInputViewControllers:]):

        Dismiss either the currently presented `_presentedQuickboardController` or
        `_presentedFullScreenInputViewController`, and invoke the UI delegate method
        `-_webView:didDismissFocusedElementViewController:` when finished.

        (-[WKContentView quickboardController:textInputValueDidChange:]):
        (-[WKContentView quickboardControllerTextInputValueCancelled:]):
        (-[WKContentView dismissQuickboardViewControllerAndRevealFocusedFormOverlayIfNecessary:]):
        (-[WKContentView textContentTypeForQuickboard]):

        Refactor `-_updateTextInputTraits:` to call a helper method (`-textContentTypeForQuickboard`) on watchOS to
        convert the current focused element information to a `UITextContentType`.

        (-[WKContentView textContentTypeForListViewController:]):
        (-[WKContentView _simulateTextEntered:]):
        (-[WKContentView textContentTypeForTesting]):
        (-[WKContentView formInputLabel]):

        Update a few internal testing hooks to handle the case where we have a `_presentedQuickboardController` instead
        of a `_presentedFullScreenInputViewController`.

        the given `interaction` to see if it's the data detector interaction before doing any work.
        This allows the media controls `UIContextMenuInteraction` to exist side-by-side and use the
        `WKActionSheetAssistant` as its delegate too (especially since it's not possible for both
        contextmenus to be active at the same time). Present the media controls contextmenu without
        a preview (it uses an empty `UIView` for proper sizing) at the location provided. Selecting
        a `UIAction` will send the `MediaControlsContextMenuItem::ID` back to the WebProcess.
        Also add support for
         - `UIScriptController.prototype.contentsOfUserInterfaceItem`
         - `UIScriptController.prototype.didShowContextMenuCallback`
         - `UIScriptController.prototype.didDismissContextMenuCallback`
        for usage in the added `LayoutTests/media/modern-media-controls/tracks-support/ios/` tests.

        Make sure we are no longer show the previous page when running a JS prompt.
        If we have not yet done a layer tree commit since the last load commit, then
        we are likely still showing the previous page. If we are asked to run a JS
        prompt / alert / confirm at this point, it would be confusing to still show
        the previous page. In order to address the issue, we now make the view blank
        in such scenario (ideally, we'd have painted the new page but this is
        currently not a trivial thing to do).

        To make the view blank, the approach chosen was to add a blank overlay view
        on top of the content. This overlay view gets taken down as soon as we
        paint the view again.

        [GPUP] Run ImageDecoderAVFObjC in the GPU Process
        https://bugs.webkit.org/show_bug.cgi?id=221317

        Reviewed by Jer Noble.

        This patch adds the support to run `ImageDecoderAVFObjC` in the GPU process when the
        "GPU Process: Media" preference is on. The `RemoteImageDecoderAVF` running in the Web
        process forwards video data to the `RemoteImageDecoderAVFProxy` running in the GPU process,
        which parses the data and returns frame information ("hasAlpha" and "duration") to the
        Web process. `RemoteImageDecoderAVFProxy` will generate (decode) frames (images) after
        receiving requests from `RemoteImageDecoderAVF`. The decoded frames are transferred to
        the Web process through IOSurfaces, and the frames will be cached in the Web process.

        Under stress tests, instances of RemoteAudioTrackProxy, RemoteTextTrackProxy, and
        RemoteVideoTrackProxy might be destroyed in the GPU process when an IPC message
        comes and leads to an assertion failure.

        To fix the assertion failure, this patches removes three IPC message receivers in
        the GPU process:
        - RemoteAudioTrackProxy
        - RemoteTextTrackProxy
        - RemoteVideoTrackProxy
        Instead of using these three message receivers, this patch adds three new IPC messages
        to RemoteMediaPlayerProxy:
        - AudioTrackSetEnabled
        - TextTrackSetMode
        - VideoTrackSetSelected

        No new tests, fixing following tests:

        Along the way I made all asynchronous message replies use 8 fewer bytes by using the destination ID for the listener ID
        instead of encoding 0 as the destination ID and then encoding the listener ID.  This was needed in order to make implementing
        waitForAsyncCallbackAndDispatchImmediately possible, which looks at the destination IDs of incoming messages.
        I also made it so that if we are just snapshotting the first page, we don't send a synchronous message because we already know the page count:
        1!

        REGRESSION (r271660): Unable to interact with page after long-pressing image on images.google.com
        https://bugs.webkit.org/show_bug.cgi?id=221584
        <rdar://problem/74073581>

        Reviewed by Andy Estes.

        After long pressing on an image with an active touchend event listener, it's possible to sometimes get stuck in
        a state where further interaction with the page is impossible, due to all gesture recognizers (except for the
        touchend deferral gestures) remaining in either Failed or Ended state.

        When presenting the context menu with a long press, the touch event gesture transitions to Failed state due to
        the active touch being cancelled. Normally, this invokes `-_webTouchEventsRecognized:` with all touch points
        being released, which allows us to "lift" the deferred gesture gate by failing any deferring gesture recognizers
        that are still in Possible state (i.e. deferring native gestures).

        However, it's possible for touch deferring gestures (in particular, the touchend deferrer) introduced in r271660
        to end (i.e. call `-touchesEnded:withEvent:`) before the touch event gesture gets a chance to call
        `-_webTouchEventsRecognized:`. In this scenario, the touch end deferral gesture remains in Possible state, and
        prevents the touch event gesture from subsequently firing its action (`-_webTouchEventsRecognized:`), presumably
        because UIKit is waiting for all other gestures in the same subgraph as the touch event gesture recognizer to
        Fail.

        This effectively results in a gesture "deadlock", since the web touch event gesture recognizer won't call
        `-_webTouchEventsRecognized:` until the touch end deferring gesture has failed, and the touch end deferring
        gesture won't fail until `-_webTouchEventsRecognized:` is called. To fix this, we restore a bit of logic that
        was removed with r271193, such that we allow our deferring gesture recognizers to transition to Failed state
        underneath `-touchesEnded:withEvent:`, as long it's [1] not actively deferring any native gestures, and [2] the
        web touch event gesture has already failed, so we aren't expecting a subsequent call to
        `-_webTouchEventsRecognized:` until the deferring gesture has failed.

        Note that this check for the touch event gesture recognizer's state (condition [2] above) is necessary to
        prevent the touchend deferring gesture from failing prematurely (i.e. right before we're about to dispatch
        preventable `touchend` events).

        Add a delegate hook when a deferring gesture's ends touches; use this hook in `WKContentView` to "lift" the
        gesture gate if needed, in the case where the touch event gesture recognizer has already failed and we can't
        expect `-_webTouchEventsRecognized:` to be called with all touch points released.

        Reviewed by Adrian Perez de Castro.

        Modifier keys were not being set on "keydown" events.
        For example if you check event.ctrlKey (and other) you'll get always false when the user only typed Ctrl key
        (it'll be true when it's in combination with some other key, like Ctrl + P).
        This is due to some differences on how X system manages the modifier keys (see http://crbug.com/127142#c8),
        but this patch will align WebKitGTK with other platforms and browsers on this case.

        In case of GPUProcess audio capture, send the request to capture to WebProcess like done for iOS.
        WebProcess is then responsible to get audio samples from GPUProcess and forward them to UIProcess.

        If a client tries to exit fullscreen mode when there is no fullscreen

        Rename requestFullscreenModeWithCallback to requestCloseAllMediaPresentations
        because the completion handler is only called when all media presentations
        are closed. requestFullscreenModeWithCallback makes it seem like we

        We are seeing crashes in ResourceLoadStatisticsDatabaseStore::setPrevalentResource
        as a result of trying to use a nullopt domainID value. In theory this should
        never be WTF::nullopt but is because of a failing SQLite query in
        ResourceLoadStatisticsDatabaseStore::domainID which reports the error "not an error".

        To fix this we should check the domain ID and return early with a
        debug assert in setPrevalentResource() if it is WTF::nullopt to avoid
        a crash. Additionally, we should add more information to the logging
        statement, specifically the SQLite statement string, to try and debug further.

        It is possible that client asks to stop/abort pending requests, which are waiting for permission check to be 
        done. In our current implementation, SpeechRecognitionPermissionManager would perform permission checks for
        these cancelled requests, which is unnecessary and may cause extra prompts. We should let 
        SpeechRecognitionPermissionManager check if request is still valid before checking permissions.

        When Safari on macOS is launching, it calls registerURLSchemeAsSecure and registerURLSchemeAsBypassingContentSecurityPolicy.
        This causes the network process to launch before the app has finished launching.  Since values are stored in the UI process
        and sent in NetworkProcessCreationParameters whenever a network process starts, so it's not necessary to start the network

        For video sources tied to a remote source in GPUProcess, we are calling requestToEnd instead of end
        since the same remote source may be shared with other cloned video sources.
        In that case, the source in WebProcess should be considered as ended as soon as requestToEnd is called.

        This is important as in case of GPUProcess, we are recreating sources that are not ended.
        We were thus recreating a source which was actually ended in WebProcess.
        This appears in particular on iOS where only one source can be active at a time.

        A further refactoring should probably change the way we clone video sources given we are now supporting size and frame rate adaptations in RealtimeVideoSource.

        Before r267763 we could have an app launch, allocate a WKWebView, and set _resourceLoadStatisticsEnabled
        all without having a network process launch.

        When setting _resourceLoadStatisticsEnabled, we don't need to launch a network process if we haven't already
        because when we do, WebsiteDataStore::parameters will send the correct value.  I added a test that verifies this doesn't
        launch the network process if it hasn't already been launched.

        We also don't need to update the process assertion or the process suspension state if there is no network process.

        sendNetworkProcessXPCEndpointToWebProcess is also called when opening Safari on iOS and would be the next thing to
        unnecessarily launch the network process during app initialization.  I manually verified that if we add an early return
        if there is no network process yet, we do send the XPC endpoint to the web process when the network process does launch
        through the call site in sendNetworkProcessXPCEndpointToAllWebProcesses.

        I verified on my phone that this is the minimal change needed for Safari on iOS to not launch the network process before
        application:didFinishLaunchingWithOptions: is called as it did before r267763.

        has no sync info (it was synthesized by MediaSample), return kCMBaseObjectError_ValueNotAvailable

        Tapping on a select element should display an context menu that allows
        users to choose one of the specified options. Rather than presenting a
        UIPickerView, tapping on select elements now create UIContextMenuInteractions,
        similar to date and file inputs.

        MachSemaphore does not work well with IPC messages
        https://bugs.webkit.org/show_bug.cgi?id=220919
        <rdar://problem/73826848>

        Reviewed by Sam Weinig.

        Move WTF::MachSemaphore to WebKit IPC::Semaphore. Currently the
        MachSemaphore is useful only in cross-process IPC, implemented by the
        IPC::.

        Adds a stub IPC::Semaphore to all non-COCOA platforms, so that
        constructors do not need to ifdef'ed to be able to compile platforms
        that do not yet support GPU process fully.

        Implement move constructor and move assignment operator for Semaphore.
        Makes it possible to create types that hold Semaphore but still are
        decode()able from a IPC message. The decoded objects are held with
        Optional, and this forces the subobjects to have move assignment
        operator.

        Add asserts that the moved-away object is not used. Add the asserts as
        asserts on the call return values, so the values are also checked on
        normal objects on normal operation.

        Implement an encoder and decoder for IPC::Semaphore. Makes it possible
        to send it via IPC as its own type, not as MachSendRight.

        As an example, changes existing uses of MachSendRight for semaphores in
        messages as Semaphores, described below.

        No new tests, a refactor.

        Changes RemoteRenderingBackend to receive its parameters from the normal
        message parameters instead of redundant
        RemoteRenderingBackendCreationParameters. The IPC generator already
        generates 1:1 identical structure, it is just the message
        Messages::GPUConnectionToWebProcess::CreateRenderingBackend. There is no
        need to double-wrap the simple list of parameters. The double-wrapping
        is a problem: The message system parameters are of ownership "const
        reference", which is what is expected.
        RemoteRenderingBackendCreationParameters contents were of ownership
        "value", which works as expected only for simple primitive types.
        Essentially previously calling the IPC function meant transfering
        objects to RemoteRenderingBackendCreationParameters. This is not how the
        IPC system is meant to work. The intention of a IPC call is to, by
        default, reference its arguments for the purpose of encoding.

        * WebProcess/GPU/media/RemoteAudioDestinationProxy.h:

        Changes RemoteAudioDestinationProxy to send its own semaphore from
        WebProcess to GPUProcess. Previously the semaphore would be sent back by
        RemoteAudioDestinationManager. Previously the code structure is more
        complicated than neccessary, as the semaphore holder was being
        null-checked, reset and re-seated. The WebProcess gets already to choose
        the semaphores GPUProcess uses, so this should not increase security
        surface. The change chosen here side-steps the shortcoming of the IPC
        system where unpacking objects from the Reply messages mandates that a
        constructed version of that type exists. For previous MachSendRight
        empty-constructed object is simple, but for MachSemaphore
        empty-constructed object creates unnecessary complication that is not
        required otherwise at the moment. The alternative to what was chosen
        here would be to hold with Optional<MachSemaphore> and add a
        empty-initializing constructor to hold the object where to unpack the
        semaphore object from the Reply.

        [macOS] Regression(r271897) Prewarmed WebProcesses no longer get a user-friendly process name in Activity Monitor
        https://bugs.webkit.org/show_bug.cgi?id=221094
        <rdar://73658122>

        Reviewed by Per Arne Vollan.

        Prewarmed WebProcesses currently do not have a network process connection because they do not have a sessionID yet
        and initiating a connection to the network process currently requires a sessionID. r271897 made it so that
        WebProcess::updateProcessName() early returns when there is no network process connection, which means that our
        prewarmed WebProcesses no longer get the "Safari Web Content (prewarmed)" user-friendly name in activity monitor.

        This patch relies on the fact that we are allowed to talk to launchservices when WebProcess::updateProcessName()
        gets called during process initialization (The sandbox extension gets revoked during process initialization right
        after calling updateProcessName). As a result, if updateProcessName() gets called during process initialization,
        we now set the process name directly within the process instead of messaging the network process. This fixes the
        issue with prewarmed WebProcesses.

        This patch also gets rid of the early returns when the network connection is not present and calls
        ensureNetworkProcessConnection() instead. We want to make sure to set the process name even if the process does
        not have a network process connection yet (either because none has been initiated yet or because the network
        process crashed).

        Finally, this patch replaces some WTFLogAlways() for error cases with RELEASE_LOG_ERROR() so that the errors
        stand out in the logs.

        Make LibWebRTCCodecs listen to GPUProcess crash on creation of LibWebRTCCodec.
        Set the connection also at the same time.
        This allows to remove the hop to main thread when creating/releasing encoders and decoders.
        Everything now happens in the dedicated queue, in particular updating of m_connection, encoder and decoder connections,
        as well as encoders and decoders maps.
        When using encoder/decoder connection outside of the dedicated queue, a lock is needed.

        Update LibWebRTCCodecs use of gpu process when creating a peer connection so that this happens in main thread.

        In case of process crash, we do some setup in main thread (listening to IPC messages for instance).
        But most of the work is done in a task run in the dedicated queue.
        In this task, we set the new IPC connection of all running decoders and encoders.
        We also send IPC message to recreate encoders and decoders.
        For that purpose, we store some states in encoders and decoders.

        2. It adds a new mode in AuthenticatorManager to connect it to the new _WKWebAuthenticationPanelDelegate object.
        3. It adss a new SPI to _WKWebAuthenticationPanelDelegate: -[panel:requestLAContextForUserVerificationWithCompletionHandler:],
        and adds a new method within _WKWebAuthenticationAssertionResponse to accept an LAContext from the caller to unlock

        As a step towards blocking the distributed notifications daemon in the WebContent process, color preference changes should be observed in the UI process.
        The UI process should notify the WebContent process about color preference changes. In order to be able to notify the AppKit observer in the WebContent
        process about changes with a local notification, a specific key/value needs to added to the Info.plist of the WebContent process.

        In r271879 I removed the support for data URLs in the network process for soup, assuming data URLs were always
        loaded from the web process, but that's not the case for downloads. I think we should not go to the network
        process for downloads either, but for now it's easier to fix this regression by supporting data URLs in the
        network process again. Fixes http/tests/security/anchor-download-allow-data.html.

        Some type serialization encoders are implemented in Encoder class
        https://bugs.webkit.org/show_bug.cgi?id=220519

        Reviewed by Chris Dumez.

        Move arithmetic type and enum type serialization from Encoder to
        ArgumentCoder. This makes it a bit simpler to implement multiple
        Encoder types, as the serialization code is consistently separate
        from the Encoder. WebGL SHM IPC stream extensions would eventually
        need a similar but slightly different Encoder.

        Since Encoder is intentionally coupled with the Decoder, do the
        corresponding modification to Decoder class for consistency.

        Reimplement Has{Legacy,Modern}Decoder for ease of forward declaration
        and (perhaps?) in a bit simpler terms.

        Encoder::operator<<() and Encoder::encode() were the same function.
        Remove Encoder::encode().

        No new tests, a refactor.

        After r271965, the WebContent process is no longer allowed to connect to the Launch Services daemon. This introduced a crash
        in the WebContent process when color preferences were changed in System Preferences, since AppKit will then attempt to set
        application information with Launch Services, which causes a crash when that fails. This patch addresses this issue by
        overriding the AppKit method that updates the specific application information with Launch Services, since updating this
        information should be required in the WebContent process.

        Adds a completion handler to WKWebView closeAllMediaPresentations.
        This required handling the case for video fullscreen, picture-in-picture,
        and element fullscreen. Closing fullscreen requires multiple async
        operations, some of which go out of WebKit scope like PIPViewControllerDelegate
        functions, so for simplicity, the callbacks are stored in
        the respective *FullscreenManagerProxy object and called when
        didExitFullscreen() is executed. Any additional calls to closeAllMediaPresentations

        Implement visibility based resource load scheduling for low priority resources
        https://bugs.webkit.org/show_bug.cgi?id=220728

        Reviewed by Geoff Garen.

        Add a simple network process side resource load scheduler. When active it limits the number of low priority resource loads
        (mostly images) that are passed to network layer. The current limit is 6 per host, reduced by any ongoing higher priority
        loads. This reduces impact of low priority loads to higher priority ones, espcially on HTTP/2.

        The scheduler also supports reprioritizing loads. This is used to let images currently in the viewport to skip the queue
        and start their loads faster.

        The feature is not enabled in this patch.

        [Mac] MediaSampleCursor::stepInOrderedMap can hang when stepping to the end of a track that hasn't been fully parsed
        https://bugs.webkit.org/show_bug.cgi?id=220555
        <rdar://problem/72910000>

        Reviewed by Eric Carlson.

        When a container has multiple tracks, CoreMedia determines the overall duration by creating
        a cursor at a presentation time of +infinity then asking for its timing info, the expectation
        being that the cursor will clamp itself to the track duration and report that in
        MediaSampleCursor::getSampleTiming.

        Previously, this could result in a hang for tracks that had not yet finished parsing, as
        MediaSampleCursor was designed to wait for samples outside the playable range. With this
        change, MediaSampleCursor no longer waits for samples outside the playable range but
        rather reports clamped timing info without waiting for a sample. If CoreMedia asks for
        information that requires a sample (e.g., sample location), MediaSampleCursor will respond
        with `kMTPluginSampleCursorError_LocationNotAvailable`. So that CoreMedia can determine
        the range of playable samples, this patch implements MediaSampleCursor::getPlayableHorizon.

        To simplify this implementation, MediaSampleCursor now assumes that decode time equals
        presentation time (for video tracks) or is invalid (for audio tracks). While here, also
        added media logging that helped debug this issue.

        [iOS] Obscured elements should not be focusable using the accessory bar
        https://bugs.webkit.org/show_bug.cgi?id=220929
        <rdar://problem/73239409>

        Reviewed by Tim Horton.

        Currently, assistable elements hidden behind unassistable elements can
        be focused using the next/previous buttons on the accessory bar. This
        behavior is undesirable since users cannot see the focused element, but
        are still presented UI to enter information into the element.

        While the current behavior has been longstanding, its undesirability was
        exposed after r269059, which made it possible to use the accessory bar
        to focus elements across focusable scopes. As a result, it became possible
        to focus a hidden input field on appleid.apple.com using the accessory bar.
        Note that the hidden field is inside a subframe, which was previously
        excluded from accessory bar next/previous operations. However, the same
        bug would still exist even if the field was not inside a subframe, which
        means that r269059 is not the root cause of the issue, but simply exposed
        a larger underlying problem.

        To prevent obscured elements from being focusable using the accessory bar,
        we now use hit testing to determine whether or not an element is obscured,
        before considering the element "assistable".

        Test: fast/forms/ios/accessory-bar-navigation-obscured-input.html

        [iOS WK2] theverge.com - rubber band scrolling at the top of the page causes an abrupt jump
        https://bugs.webkit.org/show_bug.cgi?id=220886
        <rdar://71177566>

        Reviewed by Sam Weinig.
        
        theverge.com on iOS is a page that has long main thread stalls with forced layouts on a timer
        that alter the page height; this caused the post-layout updateScrollbars() called from
        FrameView::adjustViewSize() to call scrollToPosition() after adjusting the scroll position
        to the allowed range.

        If the page laid out while rubberbanding was happening, the current scroll position would
        be negative, then clamped to 0, then sent to the UI process as a requested scroll to 0,
        triggering the jump to top in the UI process.

        There's existing code to prevent this from happening if we know that rubberbanding is
        happening; this patch makes isRubberBandInProgress() work for iOS WK2. It does so
        by having updateVisibleContentRects() push information about rubberbanding nodes onto
        RemoteScrollingCoordinator.

        We remove an unnecessary shouldUpdateScrollLayerPositionSynchronously() check in
        FrameView::isRubberBandInProgress() - if it's true, then the scrolling coordinator
        won't see any rubberbanding nodes anyway.

        [iOS WK2] Make the "in stable state" bit in visible content rect updates more fine-grained

        Reviewed by Tim Horton.

        VisibleContentRectUpdateInfo contains a single "in stable state" bit, but in a future
        patch the web process will need to know if the UI process is rubberbanding. In addition,
        we can fold "isChangingObscuredInsetsInteractively" into the same state bits.

        So give VisibleContentRectUpdateInfo a OptionSet<ViewStabilityFlag>.

        To give the correct state for non-main UIScrollViews, have _scrollViewIsRubberBanding
        take the UIScrollView in question, and only include isChangingObscuredInsetsInteractively
        if the question is being asked of the main UIScrollView.

        [macOS] Titlebar separator doesn't show when WKWebView is scrolled
        https://bugs.webkit.org/show_bug.cgi?id=220633
        <rdar://problem/71094055>

        Reviewed by Tim Horton.

        Starting in Big Sur, NSWindows with a titlebar display a separator if
        there is a scrolled NSScrollView adjacent to the titlebar. Since
        WKWebViews are scrollable views, but not backed by NSScrollView, we
        need to adopt SPI to support this functionality.

        This patch updates WKWebView to conform to the NSScrollViewSeparatorTrackingAdapter
        protocol, ensuring the titlebar separator is displayed when
        necessary. Note that since WKWebViews are not actually NSScrollView's we
        don't already have the scroll position of the view in the UIProcess. To
        determine whether or not the view is scrolled, this patch adds plumbing
        so that the WebProcess can tell the UIProcess the new scroll position
        when a page is scrolled.

        that can be prevented by calling `preventDefault()` on "touchend" events are tap gestures.

        Add a hook to "lift" the gesture gate upon touchend, which allows all deferred tap gestures to either fail (in

        (-[WKContentView gestureRecognizer:shouldRecognizeSimultaneouslyWithGestureRecognizer:]):

        Replace `_touchStartDeferringGestures` with `_deferringGestures` in several call sites that need to iterate over
        all deferring gestures on the content view.

        (-[WKContentView _singleTapDidReset:]):

        When resetting the single tap gesture, ensure that the tap highlight view is removed by calling
        `-_finishInteraction`; this is because an active touchend event handler may now defer `-_singleTapRecognized:`
        until after the ending the touch, which causes `-_showTapHighlight` to be called without a matching call to
        remove the highlight. Since we know that the synthetic tap gesture must eventually be reset after recognition,
        this is a more suitable catch-all for removing the tap highlight.

        (-[WKContentView deferringGestureRecognizer:shouldDeferOtherGestureRecognizer:]):

        For the "touchend" deferring gesture recognizers, partition all tap gestures on the content view into three
        subgraphs that mirror the extant gesture subgraphs currently used for the "touchstart" deferring gestures. This
        ensures that synthetic clicks always remain fast when the blocking double tap gesture is disabled, and that
        other tap gestures (such as the text interaction multi-tap gesture) are still immediately reset.

        Netflix uses a "pointerleave" event over their playback controls to trigger setting their "fade out controls"
        timer, but a "pointerleave" event isn't fired when the element moves out from under the pointer (either due to

        Work around this behavior by sending a synthetic mouse event after entering fullscreen, which causes the

        We previously discovered that we need to either (a) manually zero the MessageInfo struct

        This seemed to fix our valgrind warnings when bmalloc was in use, but not when bmalloc is
        disabled, as is good practice when valgrinding.

        Turns out we need to zero (or pack) the AttachmentInfo struct as well. Let's go with zeroing
        it, since all its members are trivially copyable, so that's safe to do.

        For good measure, we'll implement a copy constructor and do so there as well. Do this for
        MessageInfo too, to round out the original fix to MessageInfo.

        Since AttachmentInfo and MessageInfo are no longer trivially-copyable, we now need to cast
        them to void* when using memcpy in order to avoid -Wclass-memaccess warnings from GCC.

        Reviewed by Carlos Garcia Campos.

        The process launcher currently uses a child setup function to close the server end of its
        IPC socket. But this is totally unnecessary because this socket always uses CLOEXEC. So the
        child setup function is redundant.

        This is step one towards making Eclipse not crash when its UI process JVM is using a huge
        amount of memory. In such conditions, fork() will fail due to OOM, but posix_spawn() will
        still succeed. A child setup function forces GLib to use fork() instead of posix_spawn().
        However, this commit is not sufficient to fix Eclipse, because GSubprocess itself sets its
        own child setup function.

        This assertion is hitting on the debug GPUProcess bot. SharedBitmap subclasses ThreadSafeRefCounted

        [iOS] Emoji keyboard covers text field on twitter.com/messages
        https://bugs.webkit.org/show_bug.cgi?id=220664
        <rdar://problem/68400471>

        Reviewed by Devin Rousso.

        After iOS 14, the emoji software keyboard layout now includes a search field that can be used to filter for
        specific emojis. This slightly increases the overall height of the software keyboard when the emoji keyplane is
        active; in turn, this means that if the selection or caret is positioned right above the top of the software
        keyboard when the normal (alphabetic) keyplane is active, switching to the emoji keyplane will cause the
        keyboard to overlap the selection, making it difficult to see inserted text.

        To address this, add a mechanism to detect when a change in the bounds of the software keyboard causes a visible
        selection or caret rect to become overlapped, and react by scrolling to keep the selection visible. This has the
        effect of fixing this bug by scrolling to reveal the text field after switching to the emoji keyboard, but it
        also has the effect of scrolling to keep the selection visible after detaching a connected hardware keyboard,
        in the case where it would've otherwise been overlapped by the (much taller) software keyboard that appears.

        Unfortunately the unit test added by r248139 is macOS-only because WKOpenPanelParameters is only available on macOS and it would
        require a large and risky amount of refactoring to add SPI on iOS to test this because iOS uses WKFileUploadPanel instead.

        [GPUProcess] Move DOM / Canvas rendering off the main thread in the GPUProcess
        https://bugs.webkit.org/show_bug.cgi?id=220476

        Reviewed by Simon Fraser.

        Move DOM / Canvas rendering off the main thread (and on a high-priority serial WorkQueue) in the
        GPUProcess by making RemoteRenderingBackend a WorkQueueMessageReceiver. There is a serial WorkQueue
        per RemoteRenderingBackend, which means each WebPage gets its own WorkQueue.

        A/B testing shows this mostly perf-neutral (could be a slight progression on some hardware). I believe
        this new architecture should also give us more optimization opportunities in the future. For example,
        we may be able to more aggressively wait on the cross-process semaphore when waiting for new DisplayList
        entries without worrying about blocking the main thread.

        I have run layout tests in Debug on both macOS & iOS with the GPUProcess enabled and I believe I
        have fixed all the crashes that were discovered.

        <rdar://problem/72375494>

        Reviewed by Darin Adler.

        A crash report suggests that SOAuthorizationSession::dismissViewController could crash at evaluating m_page.
        This could only happen if the SOAuthorizationSession object is freed. The stack trace starts with callbacks
        from NSNotificationCenter, which capture a RefPtr of the SOAuthorizationSession object and should guarantee
        the lifetime of the object. So it contradicts the crash report.

        One of the possible explanations is that the RefPtr is somehow over-released within NSNotificationCenter since
        it's not thread-safe. To fix that, the RefPtr can be made thread-safe.

        No tests.

        <rdar://problem/57616019>

        Reset the user directory suffix before getting the sandbox data vault directory with confstr. We do not want to include the user 
        directory suffix, since the sandbox data vault will then end up inside the host process' cache folder, which is undesirable. 
        Also, creating the data vault directory with confstr can fail under some circumstances if the user directory suffix is not empty. 
        This patch also changes how we next set the user directory suffix for the process. Instead of setting the environment variable 
        DIRHELPER_USER_DIR_SUFFIX, we can use the SPI _set_user_dir_suffix. The behavior should be identical, but I believe it is better 
        to use SPI for this.

        Restores the implementation of `WKBundleNodeHandleSetHTMLInputElementSpellcheckEnabled`, which was removed in

        Double tap to select content did not work on grammerly.com on iPad because this is a desktop website run on a touch-based device,
        and there was a script running that would clear the selection on a mouseDown event. When we would send synthetic click events to the page
        we would first update the selection and then on completion of the tap, we would dispatch a mouseDown and mouseUp event on iOS. On Mac, we
        update the selection between the mouseDown and the mouseUp, so in order to bring us more in line with mac/mouse behaviors, we are now saving
        the information needed to update the selection when we believe we are in the middle of a potential tap, and then setting the selection between
        these two events. This makes for a more expected change of events, and does not let grammerly.com clear a valid selection based off of synthetic 
        clicks.

        When sending IPC to the web process from the UI process, it's possible for the `WebProcessProxy`'s IPC
        connection to be null in the case where the web process is still in the act of launching. In the case of
        asynchronous IPC, we handle this by queueing the IPC message on the `WebProcessProxy` in the case where the
        connection hasn't been created yet (refer to `AuxiliaryProcessProxy::sendMessage`). However, in the case where
        we're sending a sync message, we assume that the IPC connection exists in `MessageSender::sendSync`, which
        causes us to crash with a null dereference.

        To fix this, remove the debug assertion in `MessageSender::sendSync` and return a null `SendSyncResult` in the
        case where the connection has not been created.

        We were sending the sandbox extension later when enabling remote inspector.
        But this is not soon enough for inspecting service workers.
        For that reason, send the sandbox extension at process init time based on whether develop menu is on or not.

        Manually tested by validating that Develop Menu can list running service workers.

        Make sure that if NetworkProcess clears DOMCache, it also clears service worker registrations
        https://bugs.webkit.org/show_bug.cgi?id=220408
        <rdar://problem/72360003>

        Reviewed by Alex Christensen.

        It is expected that clearing DOM cache mandates clearing service worker registrations
        as service workers expect cache entries added at install time to stay.
        It is hard for clients to enforce this so it is best to handle it in Network Process.
        When DOMCache is cleared, service worker registrations will also be cleared.
        The reverse is not guaranteed.

        No new tests, this has no behavior change. It will fix excessive
        logging when running tests.

        We do not need to log a discrepancy between these states
        for WebKitTestRunner or TestWebKitAPI because they are sometimes treated
        like web browsers but need to turn ITP on/off for specific tests, so
        these states will not always match.

        a new RemoteAudioSourceProvider (since RemoteAudioSourceProvider is owned by
        MediaPlayerPrivateRemote). As a result, RemoteAudioSourceProvider does not need to do anything
        to deal with a GPUProcess crash. However, we need to make sure it only interacts with the
        GPUProcessConnection that existed when it was constructed.

        IPC receiver is a built-in message receiver that has few async messages.

        AsyncReply receiver is a built-in message receiver that has one async message

        <rdar://problem/72275412>

        Reviewed by Chris Dumez.

        This patch adds a mechanism for the GPU process to wait for a short duration (~30 microseconds) after it has
        finished reading all available data in its shared item buffer; if the web process writes additional data to the
        item buffer (thereby bumping the unread bytes counter) during this time, we immediately resume processing the
        new display list items in the GPU process, rather than wait for a new wakeup message.

        This allows us to avoid the cost of going to sleep just to immediately wake up in the GPU process, in the case
        where the web process is writing display list items at a very fast rate and the GPU process just happens to
        catch up (i.e. advance `unreadBytes()` to 0).

        whether we should eagerly go to sleep after processing all known items. In other words, if the wakeup message is
        being sent as a result of flushing the image buffer, we don't want to unnecessarily wait for more items;
        however, if the wakeup message is being sent as a result of exceeding the (currently) 512-item hysteresis, then
        we can probably expect more items to stream in, so it's more optimal to wait after finishing all known display

        coordinate the act of waiting for new item data in the GPU process. A shared display list handle now contains
        an atomic `waitingStatus` flag indicating whether the GPU process is in the process of waiting for more items,
        and also whether the web process has acknowledged the fact that the GPU process is waiting (thereby putting the
        GPU process in a state where it is waiting to resume processing). Along with this enum, we also add two new
        8-byte values to the header section: an offset to begin reading item data after resuming, and 8 bytes for an
        identifier indicating the new destination (for the purposes of display list rendering, this is a
        RenderingResourceIdentifier, though this will be different for WebGL).

            +------------------+

        There are three main ways in which this state machine may transition, numbered [1]-[3] in the above diagram.

        [1] When the GPU process finishes processing available items, it enters Waiting state, indicating that it is now
            waiting for additional item data. This corresponds to the call to `DisplayListReaderHandle::startWaiting`.

        [2] When the web process bumps the unread count of an item buffer, if it has a pending wakeup message or would
            otherwise need to schedule a pending wakeup message, see if we can instead simply tell the GPU process to
            resume processing, instead of sending a wakeup message. This corresponds to a call to the helper method
            `DisplayListWriterHandle::tryToResume`.

        [3] If the maximum wait duration (~30 microseconds) has passed (i.e. scenario 3a) or if the web process has
            transitioned us from Waiting to Resuming state (i.e. scenario 3b), then transition back to NotWaiting. In
            both scenarios, this corresponds to a call to `DisplayListReaderHandle::stopWaiting`. In the case where we
            transitioned from Resuming state, we can immediately continue processing display list items.

        In the case where we successfully resume, we're essentially "re-waking" the GPU process without the overhead of
        an additional IPC message, using the same shared display list handle. Since this would've otherwise been a
        separate wakeup message, we need to be careful that we continue processing display list items from the correct
        offset into the shared display list handle, and using the correct destination image buffer. This is because the
        writable offset of the item buffer may have been reset in the middle of waiting by the web process, or the
        destination image buffer may have changed while waiting. To handle these scenarios, we introduce the
        `ResumeReadingInformation` struct, which contains both of these pieces of information. An instance of this
        struct exists in the shared memory header section; this is written by the web process immediately prior to
        transitioning to Resuming state, and read by the GPU process when transitioning from Resuming to NotWaiting.

        DisplayListWriterHandle::tryToResume method, giving it the new offset to begin reading items from as well as the
        destination image buffer to which we should apply display list items. If we successfully tell the GPU process to
        resume reading, then we can clear out (or avoid storing) wakeup message arguments and avoid sending an IPC
        wakeup message.

        Refactor some logic around touch event deferring gesture recognizers
        https://bugs.webkit.org/show_bug.cgi?id=220345

        Reviewed by Tim Horton.

        Rename `_deferringGestureRecognizerForFoo` to `_touchStartDeferringGestureRecognizerForFoo`, to make it clear
        that these deferring gestures are only intended to defer native gestures until the "touchstart" event has been
        handled.

        This distinction becomes important once I introduce deferring gesture recognizers that defer the "touchend"
        event, and prevent gestures that activate upon touch end (i.e. various types of tap gesture recognizers).

        See below for more details.

        Rename this to `-_doneDeferringTouchStart:`.

        Deleted. This logic has been moved to WKContentView (see below).

        Additionally refactor this code so that this fallback logic for lifting the gesture gate exists inside
        `WKContentView` (after ending all touches), rather than inside the deferring gesture recognizer. While this
        doesn't affect the extant touch start deferring gestures, it will ensure that touch end deferring gestures won't
        get reset prematurely due to the web touch events gesture recognizer ending before the touch end deferring
        gesture.

        REGRESSION (r261157): Crash in WKSelectPopover when running as iPhone app on iPad
        https://bugs.webkit.org/show_bug.cgi?id=220065
        <rdar://problem/71932792>

        Reviewed by Darin Adler.

        r261157 changed how WebKit determined the user interface idiom for
        WKWebViews that were created in daemons. Since daemons do not create
        UIApplications, WebKit cannot use UIDevice in these instances. Instead,
        the user interface idiom determination logic was updated to include
        a check for device hardware, using MobileGestalt, in cases where no
        UIApplication was created.

        Since WebKit only determines the user interface idiom once (then
        storing the obtained value), the added determination logic breaks
        down for iPhone apps on iPad. Consider the following sequence of
        events, eventually leading to a crash when interacting with a
        <select> element:

        1. A WKWebView is created prior to UIApplication initialization. This
           can be achieved by creating one in another class's "load" method.

        2. Since the app is physically running on an iPad, WebKit determines
           the user interface idiom to be "iPad" and saves this information.

        3. Once the app actually launches, UIApplication is initialized.
           Since this is an iPhone app on iPad, the actual user interface
           idiom is "iPhone". However, WebKit does not know this, since
           it uses the saved user interface idiom from (2).

        4. When tapping a <select> element, WebKit checks its saved idiom,
           an attempts to present a UIPopoverController (the standard behavior
           under the iPad idiom).

        5. However, since the actual idiom is iPhone, UIKit throws an
           NSInvalidArgumentException, since UIPopoverController
           should not be used when running under the iPhone idiom.

        A simple fix for the crash would be to call into UIKit to check the
        idiom each time it is required, rather than relying on the saved bit.
        However, this does not address the more general issue, which is that
        WebKit's saved idiom and the actual idiom can be out of sync.

        Consequently, the approach taken is to update the saved idiom when
        it changes. This should only occur when a UIApplication is initialized.
        Hence, we listen for UIApplicationDidFinishLaunchingNotification,
        and if the actual idiom is different from our saved idiom, we update the
        saved idiom and also notify the WebProcess.

        WebKit IPC generator tests have duplicate receiver names, limiting the implementation
        https://bugs.webkit.org/show_bug.cgi?id=220236

        Reviewed by Chris Dumez.

        IPC test message receivers defined multiple receivers with same name.
        Rename the test message receivers based on what feature they test. No
        change in the non-test code.

        The IPC works with message identifier defined by the MessageName type.
        Having multiple clashing receiver names is problematic because a MessageName
        is defined by pair <receiver name, message name>. Since different receivers
        might have different kinds of messages with same message name, these might end
        up mapping to two conflicting message kinds.

        The rename of test classes makes the tests conform to the already used contract
        that the MessageName is globally unique to each individual conceptual message
        because the receiver names are unique.

        This enables further implementations that make decisions based on the
        message name. Example is to decide whether a message is synchronous or
        not. This cannot be implemented generally if there is multiple different kinds of
        messages with same name.

        Rename the test message receiver files based on the receiver name. This is
        more consistent with the existing convention used in the actual code.

        Move the script test results from the Scripts/ directory to a tests/ subdirectory
        of the tool. This is to not fill the Scripts/ directory with Scripts/webkit/ related
        test result data.

        Adds previously missing test result file MessageArgumentDescriptions.cpp, which was not added
        when the feature was implemented.

        We should not allow speech recognition on page invisible to user, because page may get content of captured audio

        Reviewed by Youenn Fablet.

        We currently only allow one page to capture media at a time and we did this by muting (stop capture in) other 
        pages. To make speech recognition work with this behavior, two changes are made:
        1. when page is muted, mute audio capture source used for speech recognition on the page. This will
        ultimately fail recognition.
        2. when speech recognition is about to start, make sure other pages are muted for capture.

        There is no need to replay back the DrawImageBuffer immediately after it
        was recorded. The worry was the source ImageBuffer may change before 
        replaying back the DrawImageBuffer into the destination ImageBuffer. But
        this should not happen with the shared memory buffer because the order
        of drawing among multiple ImageBuffer is preserved.

        Simplify CARingBuffer usage with SharedMemory storage

        Reviewed by Geoff Garen.

        Simplify CARingBuffer usage with SharedMemory storage:
        1. There are now 2 storage types:
           - ReadOnlySharedRingBufferStorage: Used by the reader
           - SharedRingBufferStorage: Used by the writer
           One type inherits the other. This allows the API to be a bit
           clearer and we can drop the m_readyOnly flag.
        2. Drop SharedRingBufferStorage::updateReadOnlyStorage() function. Instead, the reader
           can now construct a new ReadOnlySharedRingBufferStorage directly of the SharedMemory
           handle and pass it to the CARingBuffer constructor.

        Reviewed by Simon Fraser.

        Three methods of canvas readback (`toDataURL`, `toData`, and `toBGRAData`) currently cause the web content
        process to crash when enabling GPU process for DOM rendering. This is because we attempt to call into the
        respective methods on the image buffer backend following r270342, which unconditionally fire release assertions.

        Instead of using the proxy image buffer backend object in the web process, we need to communicate with the
        platform `RemoteImageBuffer` in the GPU process. To do this, we add some plumbing through
        `RemoteRenderingBackendProxy` and `RemoteRenderingBackend`, and override the `toDataURL`, `toData`, and
        `toBGRAData` methods on `RemoteImageBufferProxy` in the web process to request data from the remote rendering
        backend instead.

        being cancelable.

        Instead, synthetically defer the "Begin" phase to the first event in a
        given gesture that has non-zero deltas, and just short-circuit any
        zero-delta events entirely.

        This way, WebCore can continue with its existing only-the-first-event-is-cancelable
        logic, and we are assured that the first event that WebCore sees is also
        the first event that the page sees, and is a Begin-phase event.

        the state of the previous gesture leaks into the new gesture. Existing
        API tests caught this, I just apparently failed to run them after

        Stop leaking an XPC boost message to XPC services on builds where RunningBoard is able to give the right
        priorities to our XPC services based on the type of RunningBoard assertion is being held. There is no

        Reviewed by Geoff Garen.

        The issue was with the following line in AudioSourceProviderAVFObjC::prepare:
        `m_ringBuffer = m_ringBufferCallback(description, capacity).moveToUniquePtr();`

        In the case where m_ringBuffer was non-null before the assignment, we would have
        2 RingBuffers that would coexist for a very small period of time. When the new
        one was created, we would send an IPC to the remote process with the shared
        memory handle of the new RingBuffer. However, very shortly after, the old
        ring buffer would get destroyed, causing us to send another IPC to the remote
        process with a null handle (since the shared memory associated with the old
        ring buffer is getting destroyed). As a result, of this ordering issue, the
        remote process would end up with a RingBuffer with a null shared memory handle
        and no audio would be rendered.

        We could have addressed the issue like so:
        ```
        m_ringBuffer = nullptr;
        m_ringBuffer = m_ringBufferCallback(description, capacity).moveToUniquePtr();
        ```
        However, this would be super fragile. Instead, I have made the following changes:
        1. If there is already a ringBuffer, reuse it instead of reconstructing it.
           Calling allocate() with the new parameters on the existing ring buffer is
           sufficient in this case.
        2. Because of 1, the ring buffer creation callback no longer needs to call
           CARingBuffer::allocate().

        I also made the following changes to make the code simpler and to reduce code
        duplication:
        - The storage change handler passed to SharedRingBufferStorage is now given
          as parameter the CAAudioStreamDescription & frameCount. What the handler
          always does is send an IPC to the remote process to tell it that the
          storage changed and in all cases, it needs to provide these 2 parameters
          as well. This is because the remote process will need to call
          CARingBuffer::allocate(), which requires those 2 parameters. This
          simplifies our code in some cases since we no longer need a mechanism
          to retrieve those 2 parameters from inside the storage change handler.
        - The logic of the StorageChange IPC recipient to update its ringbuffer
          with the new shared memory handle is complicated and was duplicated
          in a LOT of places. To address this, I introduced a new
          SharedRingBufferStorage::updateReadOnlyStorage() function which does
          exactly what we need.

        [GPUProcess] Replace WebAudio rendering timer with a cross-process semaphore
        https://bugs.webkit.org/show_bug.cgi?id=219964

        Reviewed by Geoff Garen.

        r270907 replaced the per-rendering quantum IPC from the GPUProcess to the
        WebProcess with a very high-frequency timer in the WebProcess to trigger
        the rendering. While this works, this seemed a bit fragile and it also
        adds some latency to avoid missed frames.

        In this patch, I am replacing the high-frequency timer introduced in r270907
        with a cross-process semaphore. When the WebProcess asks the GPU process
        to create an audio device, the GPUProcess sends it back a MachSendRight
        to the "rendering" semaphore. The WebProcess then starts a high-priority
        AudioThread which waits this semaphore to be signaled to render a quantum.
        Whenever render() gets called on the GPUProcess side, the GPUProcess
        simply signals the "rendering" semaphore, causing the WebProcess to do
        the rendering of a quantum. As was the case before, the WebProcess stores
        rendered buffers into the RingBuffer it shares with the GPUProcess and
        the GPUProcess fetches from the RingBuffer as needed.

        [GPUProcess] Avoid doing an IPC per rendering quantum when using WebAudio
        https://bugs.webkit.org/show_bug.cgi?id=219818

        Reviewed by Geoff Garen.

        Previously, the GPUProcess was sending an IPC to the WebProcess to request to rendering
        of each quantum, which was very inefficient and a big regression compared to when we
        do not use a GPUProcess.

        To address the issue, we now start a rendering timer on the WebProcess side when rendering
        starts, so that the WebProcess renders each quantum as needed, without needing an IPC from
        the GPUProcess. Whenever a quantum is rendered, the WebProcess adds it to the RingBuffer
        it shares with the GPUProcess.

        To make sure that the WebProcess' writer keeps up with the GPUProcess' reader and that it
        does not stray too far ahead, the writer keeps track of the last frame that the reader
        attempted to read. It uses this information to try and stay a few rendering quantums ahead
        of the GPUProcess, to avoid missed frames.

        When rendering a video frame to canvas, SampleCursor is invoked on the main thread in
        order to find a sync frame to render. This triggered an ASSERT(!isMainThread()) in debug
        builds, and possibly a deadlock if the cursor pointed to a sample that hadn't yet been
        parsed (because SourceBufferParser calls the 'didProvideMediaData' callback on the main
        thread).

        Resolve this by having SourceBufferParser provide parsed samples on a background queue. To
        avoid creating AtomStrings on this non-main queue, teach TrackReader to access the trackID
        as a uint64_t instead.

        SharedRingBufferStorage was holding a raw pointer to its client and we would sometimes

        the client is not guaranteed to be alive.

        To address the issue, I replace the SharedRingBufferStorage::Client with a lambda so
        that the client can protect itself in the lambda if needed. In particular,
        RemoteAudioSourceProviderProxy now protects itself in the lambda since the lifetime
        of the CARingBuffer is not tied to the lifetime of RemoteAudioSourceProviderProxy.

        GPU process sometimes hangs during MotionMark Focus when enabling GPU Process for DOM
        https://bugs.webkit.org/show_bug.cgi?id=219839
        <rdar://problem/71562635>

        Reviewed by Tim Horton.

        Fixes an indefinite hang in the GPU process that may occur as a result of this very specific corner case in
        concurrent display list processing:

        [1] Let p and q represent two item buffers, and let A and B represent two remote image buffers whose drawing
            contexts will be destinations for display list playback in the GPU process. Suppose p has k remaining bytes
            where k >= 32, and A's writable buffer is mapped to a region closest to the end of p. In practice, when this
            hang reproduces, k is a relatively small number (typically 32-40 bytes).

        [2] Additionally, suppose that the GPU process is not reading from q (i.e. q's `unreadBytes()` count is 0), and
            that the GPU process has created a corresponding RemoteImageBuffer for A, but *not* a corresponding
            RemoteImageBuffer for B.

        [3] We now append a MetaCommandChangeDestinationImageBuffer item to change destinations from A to B, such that
            p now has (k - 16) remaining bytes. In preparation for appending new items for B's display list, the logic
            in `RemoteRenderingBackendProxy::willAppendItem` clears B's writable buffer, with the intention that B will
            turn around and call out to the client layer for a new writable buffer again once it notices that it has no
            writable buffer.

        [4] If we then immediately try to append an item to B that is larger than (k - 32) bytes,
            `RemoteRenderingBackendProxy::findReusableDisplayListHandle` will see that the most recently used item
            buffer p has insufficient space, and will instead return item buffer q. We end up appending the new item to
            item buffer q.

        [5] In the GPU process, we finish processing all available item data in p. When we encounter the destination
            buffer change item, we set `m_pendingWakeupInfo` before going to sleep, due to the fact that the GPU process
            has not learned about image buffer B yet (see the last part of step [2]).

        [6] Later, in the GPU process, when we create a RemoteImageBuffer for B, we see that we have a
            `m_pendingWakeupInfo` with destination image buffer B, so we resume display list processing. However, we're
            unable to resume where we stopped, since B's display list (in the web process) immediately appended to q
            instead of p, skipping MetaCommandChangeItemBuffer in the process. This manifests as an indefinite hang
            inside `RemoteRenderingBackend::nextDestinationImageBufferAfterApplyingDisplayLists`, since we expect p to
            have a nonzero `unreadBytes()` count.

        [7] Now that the GPU process is in a broken state, the web process follows shortly -- in the Focus subtest of
            MotionMark, this manifests as a web process crash soon after the GPU process begins to hang, because
            `RemoteImageBufferProxy::ensureBackendCreated()` times out and returns null, and we subsequently dereference
            null in `RemoteLayerBackingStore::encode()` after failing to ensure the image buffer backend.

        To fix this, we target step [3]. Rather than clear B's writable buffer and expect it to append its new items to
        p, we simply hand it p's item handle -- in this case, a handle with (k - 16) available bytes -- and set its
        writable buffer before we try to append. In this scenario, doing this ensures that if we are about to append an
        item that is larger than (k - 32) bytes, we will first leave a 16-byte MetaCommandChangeItemBuffer item inside p
        before moving on to q. This eventually ensures that when the GPU process resumes display list processing after
        creating a RemoteImageBuffer for B, it will see 16 unread bytes in p and then immediately continue reading data
        from item buffer q.

        Finally, note that in this scenario, p is always guaranteed to contain at least 16 available bytes after step
        [3] (in other words, k >= 32). This is because all calls to append an item of size n bytes to an item buffer
        check that there is a minimum (n + 16) bytes remaining (via logic in `ItemBuffer::swapWritableBufferIfNeeded`),
        such that it is, by design, always possible to append a `MetaCommandChangeItemBuffer` item if necessary. As
        such, it is safe to return the most recently used item buffer's handle in step [4].

        Reviewed by Simon Fraser.

        It's possible to return prematurely with a null backend when waiting for image buffer backend creation under
        `RemoteImageBufferProxy::ensureBackendCreated()`. Consider the following scenario (where WEB and GPU denote
        events that occur in the web and GPU processes, respectively):

        1. (WEB) RemoteImageBufferProxy A is created in the web process.
        2. (GPU) RemoteImageBuffer A is created in the GPU process, along with an image buffer backend for A.
        3. (WEB) RemoteImageBufferProxy B is created in the web process.
        4. (GPU) RemoteImageBuffer B is created in the GPU process, along with an image buffer backend for B.
        5. (WEB) Something calls `RemoteImageBufferProxy::ensureBackendCreated()` on B.
        6. (WEB) We receive the `RemoteRenderingBackendProxy::DidCreateImageBufferBackend` message for A.

        B subsequently finishes waiting for backend creation because it incorrectly believes that its backend has been
        initialized, and we end up crashing downstream in `RemoteLayerBackingStore::encode()` because
        `ensureBackendCreated()` for B returned null.

        To fix this, we adopt a similar strategy to what we use in `waitForDidFlushWithTimeout()`, and repeatedly call
        `waitForDidCreateImageBufferBackend()` until the backend has been created (allowing for an arbitrary number of
        IPC timeouts or failures). Since this counter is only incremented upon timeout (or any other kind of IPC
        communication failure), we'll simply receive `RemoteRenderingBackendProxy::DidCreateImageBufferBackend` messages
        until we confirm (in the web process) that the current image buffer's backend has been initialized.

        [GPUProcess] WebAudio rendering quantum is 15 instead of 128 when the GPU Process is enabled
        https://bugs.webkit.org/show_bug.cgi?id=219797

        Reviewed by Eric Carlson.

        WebAudio rendering quantum is 15 instead of 128 when the GPU Process is enabled. This generates a lot more
        IPC unnecessarily, not to mention how WebAudio code expects a rendering quantum of 128 and could potentially
        do bad things with a lower value.

        The issue was that RemoteAudioSessionProxyManager::setPreferredBufferSizeForProcess() was iterating over
        all RemoteAudioSessionProxy objects to find out the lowest rendering quantum. If there is a proxy with
        a preferred buffer size that is not set, the value ends up being 0. When then ask core audio for a rendering
        quantum of 0, and they end up using 15 (likely the minimum).

        It makes more sense for initialization of GCrypt to occur in platformInitialize
        than in the main method of the process. This means that the process does not have
        to link gcrypt libraries and can just link WebKit only.

        The IOGPU class is the superclass of AGXDeviceUserClient, and is the preferred IOKit reference to use according to the Sandbox team.

        [GPUProcess] Cut in half amount of IPC needed to do WebAudio
        https://bugs.webkit.org/show_bug.cgi?id=219715

        Reviewed by Geoff Garen.

        Cut in half amount of IPC needed to do WebAudio. Previously, we would send 2
        IPCs per rendering quantum:
        1. RemoteAudioDestinationProxy::RequestBuffer from GPUProcess to WebProcess
        2. The response to RemoteAudioDestinationProxy::RequestBuffer which contained
           the frame bounds for the RingBuffer.

        This patch gets rid of IPC 2 by having the CARingBuffer class store its bounds
        in its memory backing. As a result, when the CARingBuffer is using a shared
        memory backing, the bounds get shared between processes, without any need for
        IPC to sync them.

        This is still too much IPC but this is a step in the right direction. We
        can hopefully get rid of (or greatly reduce) IPC 1 in a follow-up patch.

        Introduce new download API
        https://bugs.webkit.org/show_bug.cgi?id=217747

        Reviewed by Brady Eidson.

        Safari currently uses _WKDownload, which has evolved strangely over the last decade.
        In order to make a nicer interface, we need to learn from those lessons and take a step back.
        I did that, and here's what I came up with: WKDownload and WKDownloadDelegate!

        Notable changes include:
        1.  The delegate now lives on the download object instead of the process pool.
        2.  WKDownload does not conform to NSCopying because we have NSMapTable instead of NSDictionary.
        3.  publishProgressAtURL is gone.  That will be reimplemented in the UI process of the client that used it.
        4.  cancel has a completion handler to get the resume data instead of waiting for didCancel then getting it from the download object.
        5.  didFailWithError also gives you the resume data, so there is no way to get it from the download object.  That's more about a fail/cancel
            event than a property of the download.
        6.  wasUserInitiated is gone.  Instead, WKNavigationDelegate has a callback that links a navigation action (where _isUserInitiated is exposed) to the download.
        7.  redirectChain is also gone.  That can also be gotten from the link to the navigation and the download delegate's redirect callback.
        8.  _downloadDidStart is gone.  Instead, we have completion handlers that expose a WKDownload once it's started.  There's no need to
            reference the download object before then anyways.  Note: that's when the download "starts" which is before it receives the response,
            so there will be no server delay in the difference between download object availabilities.
        9.  didReceiveServerRedirectToURL now gives you the option of continuing or cancelling.  This reflects the amount of control the
            WKNavigationDelegate has.
        10. decideDestinationWithSuggestedFilename and didReceiveResponse have been merged, since they actually happen at the same time and
            NSURLResponse has suggestedFilename API.  allowOverwrite is also gone.  It wasn't used, and not really needed.
        11. didCreateDestination is gone.  That callback time wasn't really necessary.  If you need to know when it's created, wait until the first
            didWriteData callback.  The destination has definitely been created by then.
        12. shouldDecodeSourceDataOfMIMEType is gone.  It's actually not called since we adopted NSURLSession, and we should remove the related dead code.
        13. originatingFrame is gone.  On _WKDownload it was actually a non-null WKFrameInfo that often contained no information.  When information was there,
            the information access has been replaced by didBecomeDownload which links the WKNavigationResponse which has frame info on it.

        I wrote API tests for everything I could think of.

        Use NWConnection for client TCP sockets.
        This allows piggy-backing on this API for things such as proxies or certificate validation.
        Implementation does opening a TCP socket with TLS using NWConnection:
        - If the socket is created for STUN/TURN, it is sending packets as is. For receiving data, the socket
        will make sure to split received data in meaningful messages that WebProcess will process.
        - If the socket is TCP for data, sent data is prefixed with the size of the data. For received data,
        the length of the message is read and we wait to receive the whole message data to send it to WebProcess.

        We enable that new code path based on an experimental feature.
        Tested manually with TURNS servers and TCP-only connections.

        Some WebGL tests crash in WebKit::RemoteRenderingBackendProxy::willAppendItem(WebCore::RenderingResourceIdentifier)

        Fixes these assertions by resetting the identifier of the "most recently appended" image buffer
        (m_currentDestinationImageBufferIdentifier) when the image buffer is released in the rendering
        backend. We keep track of this so that we can append MetaCommandChangeDestinationImageBuffer
        items when painting into multiple image buffers; the code to do this in willAppendItem is
        actually robust against the case where m_currentDestinationImageBufferIdentifier is unknown,
        but still debug asserts.

        mouseUp: was being called by AppKit on the WKPDFHUDView instead of the WKWebView, causing the event to not make it to the PDFPlugin,
        which meant PDFKit wasn't being told it was clicked on, which means it wasn't telling WebKit to change the frame's location.
        Overriding hitTest to forward all mouse events to the WKWebView solves this problem.

        Covered by the WebKit.PDFLinkReferrer API test, which was failing on Big Sur, where ENABLE(UI_PROCESS_PDF_HUD) is true.

        Implements a beginning of a remote version of GraphicsContextGL for GPU
        process. Current implementation is using WebKit IPC.

        Implemented with a generator script implementing the IPC to pass the
        GraphicsContextGL member function calls from web process to the GPU
        process. The script is run during development time and the results are
        committed to the repo for ease of review.

        Implement the RemoteGraphicsContextGL in WebKit side. This class will
        forward calls received via IPC to the GraphicsContextGLOpenGL. At the
        moment RemoteGraphicsContextGL instance is a direct child of
        GPUConnectionToWebProcess.

        Compositing is implemented only for PLATFORM(COCOA).

        REGRESSION(r269647) [Cocoa] Consume GPU sandbox extensions early in Web page creation flow
        https://bugs.webkit.org/show_bug.cgi?id=219659
        <rdar://problem/72058396>

        Reviewed by Jer Noble.

        We need to consume GPU sandbox extensions earlier in the Web page creation flow so that API calls to things like
        muting video have the relevant mach connections available.

        This change corrects a regression introduced in Bug 218708 (r269647).

        WebDriver: add support for pen pointer events
        https://bugs.webkit.org/show_bug.cgi?id=219024

        Reviewed by Brian Burg.

        Make it possible to synthesize pointer events for any pointer type. Add pen input source to automation and
        handle it when dispatching actions.

        Implement audio capture for SpeechRecognition on iOS
        https://bugs.webkit.org/show_bug.cgi?id=219371
        <rdar://problem/71824049>

        Reviewed by Youenn Fablet.

        On iOS, audio capture is done in web process. For speech recognition, recognizer is in UI process. Therefore,
        UI process needs to ask web process to capture audio and send back data. To implement this, this patch added:
        - SpeechRecognitionRemoteRealtimeMediaSource: subclass WebCore::RealtimeMediaSource and connect to a remote 
        WebCore::RealtimeMediaSource (owned by SpeechRecognitionRealtimeMediaSourceManager::Source) in web process.
        - SpeechRecognitionRemoteRealtimeMediaSourceManager: manage all RemoteRealtimeMediaSources.
        - SpeechRecognitionRealtimeMediaSourceManager: manage all SpeechRecognitionRemoteRealtimeMediaSource.
        - SpeechRecognitionRealtimeMediaSourceManager::Source: own and monitor a local WebCore::RealtimeMediaSource.

        This structure is very similar to how we implement media capture on macOS (RemoteRealtimeMediaSource, 
        UserMediaCaptureManager and UserMediaCaptureManagerProxy), where we send data from UI process to web process
        instead. We should unify the architecture if possible.

        IPC should support non-byte aligned data references
        https://bugs.webkit.org/show_bug.cgi?id=219487

        Reviewed by Chris Dumez.

        Add a templated version of IPC::DataReference: ArrayReference<type, number of elements>.
        The number of elements can be omitted, in which case the ArrayReference
        size is determined at run-time.

        This way pointers of typed arrays such as float arrays can be transferred directly
        from the IPC message data store to the target. This is useful when implementing
        IPC for WebGL in GPU process.

        Changes IPC to support passing data references, i.e.
        DataReference or ArrayReference, as a synchronous IPC call return value.
        The caller must hold the Connection::syncSend() result (Decoder object)
        for the duration of using the data values.

        Makes DataReference an alias of uint8_t dynamic array reference.
        Unfortunately this makes the forward declaring DataReference hard.
        Due to this, changes use declaration sites to #include instead of
        using forward declarations. Removes forward declarations for headers
        where the type is not used.

        Adds various #includes to fix errors hidden by the unified build.

        Adds some WebCore:: namespace qualifications to fix errors hidden
        by the unified build.

        Update WKRemoteObjectEncoder to detect cycles when encoding objects. When a cycle is detected, we

        ScrollingPerformanceLoggingEnabled is used by a Safari performance test, so it needs to be
        easily toggleable from a script. That's easier if it's an Internal Debug preference.

        Testing also sets ForceUpdateScrollbarsOnMainThreadForPerformanceTesting but we can just use
        the ScrollingPerformanceLoggingEnabled flag, but it makes more sense to rename
        ScrollingPerformanceLoggingEnabled to ScrollingPerformanceTestingEnabled when we do that.

        Also fix how we propagate ScrollingPerformanceTestingEnabled to the scrolling tree;
        do so via ScrollingStateFrameScrollingNode as we do for the other tree-wide settings,
        removing code in TiledCoreAnimationDrawingArea::updatePreferences() that did this.

        In r270458 and in RemoteLayerBackingStore::encode(), casting the ImageBuffer

        directly.

        This may lead to crash if the backend was not created when calling its
        createImageBufferBackendHandle(). The createImageBufferBackendHandle()
        of the ImageBuffer superclass calls ensureBackendCreated() before calling
        createImageBufferBackendHandle() of the backend.

        [Concurrent display lists] Synchronize display list rendering across remote image buffers

        <rdar://problem/71747695>

        Reviewed by Geoff Garen.

        Refactors the existing concurrent display list processing mechanism, such that we no longer update the unread
        bytes count every 512 items (or when flushing the drawing context), and instead update it every time we append
        display list item data. In order to achieve this without making it impossible for multiple display-list backed
        image buffers to render simultaneously, we also add support for synchronizing display list items across
        different image buffers by using the new meta command items added in bug #219262. As detailed in the ChangeLog
        for that bug, a stream of display list data written by the web process and consumed by the GPU process is now
        structured like so:

            MetaCommandChangeDestinationImageBuffer(A)

        (Note that the `MetaCommandEnd` item has been omitted, since we no longer need to explicitly tell the GPU
        process to go to sleep with the latest iteration of this patch).

        In order to write display list data conforming to this format, we add a mechanism to the web process that keeps
        track of the "current destination image buffer" (i.e. the image buffer that has most recently
        appended a display list item). Right before this destination is about to change, we append a new
        `MetaCommandChangeDestinationImageBuffer` item before proceeding to append display list items for the new
        current destination.

        Since we now bump the unread count every time, we need to do some additional work to avoid an excessive number
        of wakeups and sleeps in the GPU process, which would otherwise cause a massive regression. To do this, we
        introduce an item count hysteresis in the web process, such that we will wait for 512 items to be written before
        attempting to send the wakeup message. This allows the web process to get a small head start over the GPU
        process, and thus allows the GPU process to be more consistently busy over the course of a single frame.

        On the reader (GPU process) side, we make some minor adjustments so that the main display list processing loop
        of the GPU process is capable of changing destination image buffers while processing a stream of display list
        items.

        encounter a `MetaCommandChangeItemBuffer` item informing us of the next item buffer to consume).

        Make this hit the maximum `waitForAndDispatchImmediately` attempt count and "fail" only if the call to
        `waitForAndDispatchImmediately` actually times out. This change is necessary to ensure that the scenario of
        multiple image buffers simultaneously appending display list items works when all image buffers perform (non-
        blocking) flushes simultaneously, followed by a sync-wait (blocking) flush. In this situation, the web process
        may receive more than three `DidFlush` messages in rapid succession, causing it to hit this maximum limit of 3
        instantly and avoid waiting for the expected `DidFlush` message to arrive.

        * WebProcess/GPU/graphics/RemoteRenderingBackendProxy.cpp:
        (WebKit::RemoteRenderingBackendProxy::gpuProcessConnectionDidClose):

        Reset state when the GPU process is terminated.

        (WebKit::RemoteRenderingBackendProxy::willAppendItem):

        Update the current destination image buffer (`m_currentDestinationImageBufferIdentifier`). If this identifier
        changed, then we append a `MetaCommandChangeDestinationImageBuffer` item to the previous destination before
        setting the new destination image buffer. We also need to clear the new destination image buffer's display list
        before writing new items, to prevent it from overwriting shared display list item data.

        (WebKit::RemoteRenderingBackendProxy::sendWakeupMessage):
        (WebKit::RemoteRenderingBackendProxy::sendDeferredWakeupMessageIfNeeded):
        (WebKit::RemoteRenderingBackendProxy::didAppendData):

        Implement a new `ItemBufferWritingClient` hook by advancing the corresponding item buffer's unread count.
        Additionally, schedule a wakeup message in the case where the unread count was zero when we advanced, and the
        item buffer we've appended to is not "connected" to a previous item buffer by way of an item buffer change item.

        Additionally, in the case where we don't schedule a new wakeup message, check whether or not there is a deferred
        wakeup message; if there is, then decrement the remaining item count before we send the wakeup message, and send
        the message if the count reaches 0.

        (WebKit::RemoteRenderingBackendProxy::findReusableDisplayListHandle):

        Pull logic to find a shared display list handle suitable for reuse into a separate helper method, and adjust it
        so that if the most recently used display list handle has run out of available capacity, we move it to the end
        of the reuse queue and only reuse the new first shared handle in the queue if its writable offset can be reset.
        This ensures that the GPU process can always continue reading display list item data from the start of new item
        buffers -- i.e., we don't end up with the web process writing out a stream of display list data like:

           (Start) Bytes (16, 65520) in ItemBuffer[1]
                   Bytes (16, 65536) in ItemBuffer[2]

        [GPU Process] Clean up recreating the ImageBufferBackend because of GPU crashing
        https://bugs.webkit.org/show_bug.cgi?id=219007

        Reviewed by Simon Fraser.

        There is no need to store the backend parameters in RemoteImageBufferProxy.
        These parameters are now stored in the base class ImageBuffer before the
        backend is created.

        Remove the traits definition for RemoteImageBufferProxy types because
        they are wrong. All ImageBuffers have valid renderingResourceIdentifier()
        regardless whether they are remote or not. ImageBuffer::setBackend and
        ImageBuffer::submitDisplayList() are now implemented in WebCore. So no
        casting is needed.

        Web Inspector: InspectorFrontendAPIDispatcher should not ignore all exceptions

        The underlying method used for frontend expression evaluations is 
        ScriptController::evaluateIgnoringExceptions. This method calls
        evaluateInWorld and returns nullopt if an exception happens.

        Switch to using evaluateInWorld directly and using the existing ValueOrException
        type from in WebCore. Change our EvaluationResult type to use ValueOrException 
        in place of JSC::JSValue. ValueOrException is Expected<JSC::JSValue, ExceptionDetails>

        Introduce new download API
        https://bugs.webkit.org/show_bug.cgi?id=217747

        Reviewed by Brady Eidson.

        Safari currently uses _WKDownload, which has evolved strangely over the last decade.
        In order to make a nicer interface, we need to learn from those lessons and take a step back.
        I did that, and here's what I came up with: WKDownload and WKDownloadDelegate!

        Notable changes include:
        1.  The delegate now lives on the download object instead of the process pool.
        2.  WKDownload does not conform to NSCopying because we have NSMapTable instead of NSDictionary.
        3.  publishProgressAtURL is gone.  That will be reimplemented in the UI process of the client that used it.
        4.  cancel has a completion handler to get the resume data instead of waiting for didCancel then getting it from the download object.
        5.  didFailWithError also gives you the resume data, so there is no way to get it from the download object.  That's more about a fail/cancel
            event than a property of the download.
        6.  wasUserInitiated is gone.  Instead, WKNavigationDelegate has a callback that links a navigation action (where _isUserInitiated is exposed) to the download.
        7.  redirectChain is also gone.  That can also be gotten from the link to the navigation and the download delegate's redirect callback.
        8.  _downloadDidStart is gone.  Instead, we have completion handlers that expose a WKDownload once it's started.  There's no need to
            reference the download object before then anyways.  Note: that's when the download "starts" which is before it receives the response,
            so there will be no server delay in the difference between download object availabilities.
        9.  didReceiveServerRedirectToURL now gives you the option of continuing or cancelling.  This reflects the amount of control the
            WKNavigationDelegate has.
        10. decideDestinationWithSuggestedFilename and didReceiveResponse have been merged, since they actually happen at the same time and
            NSURLResponse has suggestedFilename API.  allowOverwrite is also gone.  It wasn't used, and not really needed.
        11. didCreateDestination is gone.  That callback time wasn't really necessary.  If you need to know when it's created, wait until the first
            didWriteData callback.  The destination has definitely been created by then.
        12. shouldDecodeSourceDataOfMIMEType is gone.  It's actually not called since we adopted NSURLSession, and we should remove the related dead code.
        13. originatingFrame is gone.  On _WKDownload it was actually a non-null WKFrameInfo that often contained no information.  When information was there,
            the information access has been replaced by didBecomeDownload which links the WKNavigationResponse which has frame info on it.

        I wrote API tests for everything I could think of.

        Readd ImageBufferShareableIOSurfaceBackend, the unmapped variant. The mapped variant is only used:
        - in the GPU process
        - in the Web Content process when DOM rendering in the GPU process is disabled

        The unmapped variant cannot perform most ImageBufferBackend duties, except creating an ImageBufferBackendHandle,
        which it does by cloning the existing handle. It explicitly does *not* map the IOSurface in the
        process, and is meant for use in Web Content processes that do not have access to IOSurface.

        These existing interactions may conflict with pending image extraction interactions. Luckily, since these
        interactions are both asynchronous, we're able to defer them until any pending image extraction request has
        finished, to determine whether or not they should commence. In both cases, image extraction should take
        precedence over dragging and context menus.

        Add a new long press gesture recognizer that fires on a very short (100ms) delay. This gesture is used to
        preflight image extraction requests ahead of the other long press gestures (in particular, context menus), such
        that these other gestures should be minimally impacted by the time required to perform image extraction.

        This is still a long press gesture instead of a regular gesture recognizer, since preflighting image extraction
        requests could be expensive if performed during every single gesture (i.e. scrolling, taps, etc).

        Consolidate header postprocessing scripts
        https://bugs.webkit.org/show_bug.cgi?id=219388
        <rdar://problem/71840357>

        Reviewed by David Kilzer.

        Our build system contains the following scripts to perform some
        postprocessing of headers that we export to the SDK:

            JavaScriptCore/postprocess-headers.sh
            WebKit/mac/postprocess-framework-headers.sh
            WebKitLegacy/mac/postprocess-headers.sh

        The preceding scripts are used when using the non-XCBuild -- or
        "legacy" -- Xcode build system. They are invoked in a custom Run
        Script build phase after the headers have been exported with the
        standard Xcode facility for creating frameworks.

        Alternatively, we also have the following postprocessing scripts:

            WebKit/Scripts/postprocess-header-rule
            JavaScriptCore/Scripts/postprocess-header-rule
            WebKitLegacy/scripts/postprocess-header-rule

        These scripts are used when using the XCBuild build system. They are
        invoked *during* the header export process to copy and postprocess the
        headers in one blow. They are part of a Custom Build Rule for
        exporting files ending in ".h".

        The reason why we have two sets of scripts is because of the different
        capabilities of the two Xcode build systems. The legacy system does
        not support a custom "export header" step that would allow us to copy
        and postprocess each header in a single step. Therefore, when using
        the legacy build system, we export in one build step and postprocess
        in a subsequent build step. And XCBuild doesn't like the approach
        taken by the old build system where files are exported first and then
        munged in a separate step, since that confuses its notion of the state
        of the build ("Hey! That file I exported in the previous build? I see
        now that it's been changed, so I'm going to export it again. And
        change its modification date. And then rebuild everything downstream
        that uses it."). Therefore, XCBuild added a facility for copying and
        postprocessing in one step.

        The scripts supporting each of these approaches are very similar to
        each other, such that there is a lot of code duplication between them.
        At the same time, by having two sets of scripts that are very similar
        to each other, we run the risk of "drift", where files in one set may
        get updated while their counterparts in the other set are not.

        Address this duplication by making the scripts in the "legacy" set be
        mere stubs that invoke the scripts in the new "XCBuild" set. In doing
        this, we also fix a case of drift: the legacy-based scripts made use
        of a timestamp file to determine if headers needed to be reprocessed
        and exported, while the XCBuild-based scripts used a "process the
        files and export them if any actual changes now exist between this new
        version and any previously-exported version" approach.

        Along the way, fix a bug in WebKitLegacy's postprocess-header-rule
        that resulted in WebKitAvailability.h not being processed. The
        practical effect of this bug is that the file ended up with both macOS
        and iOS code, along with the #if that controlled which chunk of code
        was compiled, instead of just the chunk of code specific to the
        targeted SDK. Normally, the unused chunk of code would get removed
        through the invocation of `unifdef`. But, because of the bug, the
        results of running `unifdef` were being discarded.

        ImageBufferShareableIOSurfaceBackend is now only used:
        - in the GPU process
        - in the Web Content process when DOM rendering in the GPU process is disabled
        In both cases, the process that uses ImageBufferShareableIOSurfaceBackend also
        originates the surface, so does not create it from a handle.

        Calling waitForAndDispatchImmediately<M> on a loop fails when multiple M messages arrive simultaneously
        https://bugs.webkit.org/show_bug.cgi?id=219240

        Reviewed by Chris Dumez.

        Fixes a race that may occur when calling `waitForAndDispatchImmediately<N>` in a loop, when multiple messages
        `N` arrive on the IPC thread simultaneously. This may result from the following sequence of events (note that
        (Main) and (IPC) in the timeline below refer to the main thread and IPC background thread, respectively):

        (Main)  Call `waitForAndDispatchImmediately`, and begin waiting.

        (IPC)   A message `N` arrives, and is handled in `processIncomingMessage` by setting the decoder of
                `m_waitingForMessage` and notifying the condition variable.

        (Main)  The main thread wakes up and starts to process `N`, clearing out `m_waitingForMessage` in the process.

        (IPC)   A second message `N` arrives. We see that `m_waitingForMessage` is null, so we don't set the decoder
                and bail. Instead, we prepare to call `enqueueIncomingMessage` and push the message onto the main
                thread, *but importantly*, we haven't done so yet.

        (Main)  Call `waitForAndDispatchImmediately` again, set `m_waitingForMessage`, and begin waiting. Since the
                incoming message that was just received above has not been enqueued yet, we are unable to avoid waiting
                due to the incoming message.

        (IPC)   We finally call `enqueueIncomingMessage`, which pushes the message `N` into `m_incomingMessages` and
                dispatches onto the main thread. However, this is too late, since the main thread is already stuck
                waiting for the incoming IPC message that we've now just enqueued.

        Two minor adjustments are required to fix this, described in the below comments. The combination of these two
        changes ensures that the scenario described above is impossible, since we'll either set `m_waitingForMessage`'s
        decoder and wake up the main thread in the case where `waitForMessage` is called before `processIncomingMessage`,
        or we'll bail early in `waitForMessage` with the enqueued IPC message in the case where `processIncomingMessage`
        runs before `waitForMessage`.

        * Platform/IPC/Connection.cpp:
        (IPC::Connection::waitForMessage):

        Move logic that checks the incoming messages queue when calling `Connection::waitForMessage` into the
        `m_waitForMessageMutex` critical section.

        (IPC::Connection::processIncomingMessage):

        Extend the critical section of `m_waitForMessageMutex` when processing an incoming message, such that it
        encompasses the part that enqueues the incoming message.

        is the change of ownerships. Prior to this change, AuthenticatorManager owns the APIWebAuthenticationPanel.
        Now, it's the opposite way.

        Since there will be a period of time that the deprecated implementation will coexist with the new implementation,
        this path also marks things that are meant to deprecate in the future to reduce confusions.

        PCM: Persist pending ad clicks and attributions so they can survive browser restart
        https://bugs.webkit.org/show_bug.cgi?id=219134
        <rdar://problem/70470129>

        Reviewed by John Wilander.

        This patch migrates Private Click Measurement to use SQLite,
        which is beneficial because it requires less in-memory storage and
        persists PCM data across browser sessions. It also updates naming
        to match naming agreed upon in standards bodies:

        - source -> sourceSite
        - campaign/campaignID -> sourceID
        - destination -> attributeOnSite
        - conversion/conversionValue -> attributionTriggerData
        - unconverted -> unattributed
        - convert(ed) -> attribute(d)

        This adds 3 SQLite tables: one for clicks that haven't been
        attributed, one for attributions that haven't been sent, and one to
        store the last time the reports were sent to make sure reports get
        sent as soon as possible if needed after a browser restart.

        Behavior is identical to existing PCM implementation with the addition
        of persistence. Existing PCM tests confirm no regressions.

        Dispatch main-thread overflow scrolls to the scrolling thread as we do for page scrolls
        https://bugs.webkit.org/show_bug.cgi?id=219213

        Reviewed by Tim Horton.
        
        Unify the behavior of overflow scrolling and page scrolling for synchronous scrolls.
        
        Somewhat surprisingly, synchronous page scrolls move layers via a dispatch to the scrolling thread in
        FrameView::handleWheelEventForScrolling(), but overflow scrolls just did main thread compositing updates
        to set the new layer positions.

        A future patch will require that the "began" event for a synchronous scroll gets back to the scrolling thread,
        so unify these code paths to have overflow scrolls also leverage handleWheelEventAfterMainThread(), via
        RenderLayer::handleWheelEventForScrolling().

        There's some fallout from this. ThreadedScrollingTree::handleWheelEventAfterMainThread() calls into handleWheelEventWithNode(),
        but in this special case that codepath needs to know that we're in a special "post main thread" mode that should
            1. Behave as if the node is latched, i.e. don't propagate to parent nodes,
               and target the node if if it's scrolled to a the min or max to allow rubberbanding
            2. Scroll even if the node has synchronous scrolling reasons
        This mode is represented by the EventTargeting value.

        Finally, EventHandler::handleWheelEventInternal() should only clear latching state if the content has called preventDefault()
        on the event.

        There are too many functions called wheelEvent() or handleWheelEvent(), making it hard
        to know which phase of handling they apply to. So rename some to handleWheelEventForScrolling(),
        which applies to the "default handling" phase after DOM event dispatch.
        
        In addition, make ScrollableArea's handleWheelEventForScrolling() virtual and have FrameView
        override it (a future patch will also add an override in RenderLayer).

        REGRESSION (r259151): The "Convert Text to Traditional Chinese" services menu action is broken

        Reviewed by Tim Horton.

        Some system services, such as "Convert Text to (Traditional|Simplified) Chinese", use `-[NSServicesMenuRequestor
        readSelectionFromPasteboard:]` to insert the contents of the given pasteboard into the current selection. After
        the changes in r259151, this requires the UI process to explicitly grant access to the contents of the given
        pasteboard, on behalf of the web content process.

        Fix the bug by adding the missing call to `grantAccessToCurrentPasteboardData`. This is only called from API in
        the UI process, so it cannot be abused by a compromised web content process to grab the contents of
        `NSPasteboard`.

        We used to launch the initial process for the inspected page from inside

        make sure the inspected page has a process to inspect.

        However, while WebInspectorProxy::connect() gets called by functions by
        WebInspectorProxy::show(), it does not get called by
        WebInspectorProxy::showConsole() for example.

        To address this, I have moved the code that launches the inspected page's
        initial process from WebInspectorProxy::connect() to

        Currently, `reservedCapacityAtStart` is defined as a constant 16 bytes, which is enough to encompass the
        contents of the header structure in a shared display list handle (i.e. an 8-byte atomic for the lock, and
        another 8 bytes for the unread count).

        Instead of hard-coding this, we could simply make this a constexpr function that returns the size of
        `DisplayListSharedMemoryHeader` (rounded up to ensure alignment of all display list item data).

        No change in behavior.

        Main thread of the GPUProcess should have same priority as main thread of the WebContent since it
        is doing rendering on its behalf.

        For now, this means that on macOS, the main threads of the GPU and WebContent processes with both

        Reviewed by Antoine Quint.

        The desktop "version" of this site uses custom media controls that don't work well on iOS
        because they rely on mouse events (which is why it was quirked in r255592). The mobile
        "version" uses the default/native media controls, so there is no issue.

        Currently, when tapping on another video with a desktop UA, the site uses its touch event
        handlers for mouse events. These handlers call `Event.prototype.preventDefault` if the event
        is not a touch event, meaning that `"click"` is not fired. This prevents new videos from
        being played.

        Rather than limit the quirk based on some DOM state (which is fragile if the site changes),
        just have the entire site default to a mobile UA.

        Rework the client operations in ThreadedCompositor::renderLayerTree() so

        Similar to this change, the GL viewport update is split from the client
        resize operation and moved into the aforementioned rendering scope. This
        change is mostly cosmetic, but it's done to neatly package all the GL

        Update RemoteRenderingBackendProxy to be a GPUProcessConnection::Client so that it
        gets notified when the IPC connection to the GPUProcess gets severed. When this
        happens, RemoteRenderingBackendProxy clears all its SharedMemory handles and
        sends IPC messages to the GPU process to recreate all the ImageBuffers we had.

        Force wheel event listeners on the root to be passive

        Following Blink (https://www.chromestatus.com/feature/6662647093133312) force 'wheel' and
        'mousewheel' event listeners on root objects (window, document and body) to be passive if
        they were not explicitly registered as non-passive.

        This behavior is controlled by an experimental feature flag, and a linked-on-or-after check
        to avoid changing behavior for apps that embed WebKit until they link against new SDKs.

        <rdar://problem/71296116>

        Reviewed by Brent Fulgham.

        When enabling all GPU runtime flags on iOS, there is an iokit-open sandbox violation for the IOKit class AGXDeviceUserClient
        in the WebContent process. When all GPU runtime flags are enabled, IOKit extensions are not provided to the WebContent process,
        which should then fall back to a set of rules allowing use of these IOKit classes, with logging. There seems to be a problem
        with the fallback for this specific IOKit class, which this patch addresses by adding an extra requirement to the rule. The
        extra requirement is that IOKit extensions have not been provided for these IOKit classes.

        [GPUProcess] Add basic GPUProcess crash handling for media playback
        https://bugs.webkit.org/show_bug.cgi?id=218825

        Reviewed by Eric Carlson.

        When the GPU process crashes and there are pending media players, we
        now relaunch the GPU process and ask those media players to reconstuct
        their private media players, reload the file and resume playback if
        necessary. This ensures that in case of a GPU process crash while the
        user is playing a video, the video just seamlessly keeps playing from
        where it was before the crash.

        Before this patch, we would end up busy looping and the WebContent process
        would use 100% CPU after a GPU process crash.

        Reviewed by Tim Horton.

        The API test is repeatedly killing the GPU process. As a result, it is possible for the
        GPUProcess to crash while RemoteAudioDestinationProxy::connectToGPUProcess() is in the
        middle of its RemoteAudioDestinationManager::CreateAudioDestination() synchronous IPC.
        The function would fail to check if the IPC was successful and proceed with an invalid
        destinationID in such cases, causing the crash.

        We now check if the sendSync() was successful. If it wasn't we now log an error and
        return early. RemoteAudioDestinationManager::gpuProcessConnectionDidClose() will get
        called later on to notify us that the GPU Process crashed and it will call
        connectToGPUProcess() again.

        No new tests, covered by existing API test that is flakily crashing.

        Update RemoteMediaPlayerMIMETypeCache to add the support for AVFoundationMSE media engine
        https://bugs.webkit.org/show_bug.cgi?id=218788

        Reviewed by Eric Carlson.

        Originally, `RemoteMediaPlayerMIMETypeCache` inherits from `MIMETypeCache`.
        It needs to implement three functions: `isAvailable()`, `canDecodeExtendedType()`,
        `supportedTypes()` through IPC messages, and the IPC message receivers in
        `RemoteMediaPlayerManagerProxy` needs to repeat the work done by `AVAssetMIMETypeCache`
        and `AVStreamDataParserMIMETypeCache`.

        Actually, `MediaPlayerRemoteFactory` only needs two functions from
        `RemoteMediaPlayerMIMETypeCache`: `supportedTypes()`  and `supportsTypeAndCodecs()`.
        We can implement these two functions with IPC messages to `RemoteMediaPlayerManagerProxy`
        and cache the results to avoid too many IPC messages. In addition, the implementation of
        the IPC message receivers in `RemoteMediaPlayerManagerProxy` can reuse the implementation
        of `AVAssetMIMETypeCache` and `AVStreamDataParserMIMETypeCache`.

        [GPU Process] Cache the NativeImage in GPU Process and allow referencing it with its RemoteResourceIdentifier
        https://bugs.webkit.org/show_bug.cgi?id=217596

        Reviewed by Simon Fraser.

        Recorder::drawNativeImage() will ensure the NativeImage is cached before
        recording the DrawNativeImage item with the renderingResourceIdentifier.

        Because RemoteImageBufferProxy is a superclass of DisplayList::Recorder::
        Delegate, it will ensure the NativeImage is cached in its RemoteResourceCacheProxy.

        If the NativeImage is registered in RemoteResourceCacheProxy for the first
        time, it is going to be sent as an IPC message to GPU. Upon receiving this
        message, RemoteRenderingBackend will cache this NativeImage in its
        RemoteResourceCache. This message has to be received for any NativeImage
        only once for its entire life time.

        When flushing the DisplayList of any ImageBuffer, RemoteImageBuffer will
        ensure the NativeImages are cached in the RemoteResourceCache are passed
        to DisplayList::Replayer so it can use them to get NativeImage for every
        DrawNativeImage with the same renderingResourceIdentifier it was recorded
        with.

        When NativeImage is bing destroyed, its destructor will call its observer
        virtual method releaseNativeImage(). RemoteResourceCacheProxy will be a
        superclass NativeImage::Observer so its overriding method will be called.
        When RemoteResourceCacheProxy::releaseNativeImage() is called it is going
        to delete the NativeImage from RemoteResourceCacheProxy and is going to
        send a message to GPU to delete the corresponding NativeImage from
        RemoteResourceCache via RemoteRenderingBackend::releaseRemoteResource().

        _WKInspectorExtension is new SPI that represents a Web Extension that uses the 'devtools'
        API to interact with Web Inspector. An extension is associated with its _WKInspectorExtensionHost.
        A WebKit client that supports Web Extensions can use this class to implement 'devtools' extension APIs.

        Add _WKInspectorExtensionHost methods to register and unregister an extension.
        Add plumbing so that the extension in registered in the frontend with WI.InspectorExtensionController.

        Later patches will flesh out the needed functionality to implement rest of the 'devtools' API.

        A long, long time ago, we realized that CFNetwork was looking in the keychain for persistent credentials,
        and in order to make the network process get credentials as the UI process, we introduced SecItemShim which
        used DYLD_INTERPOSE to intercept the calls to the security framework and synchronously message the UI process
        for those calls.  Over the last 6 years we have realized that doesn't work on iOS or Apple silicon Macs, so

        Don't look in keychain for SecKeyRef after deserializing SecIdentityRef

        In ye olden days of WebKit2, we used to use special code to serialize an NSURLCredential with an identity.
        We needed to serialize the certificate chain and a way to look in the keychain to find the private key.
        That didn't work with third party apps not entitled to look in the keychain, and it also didn't work with hardware
        keys that retain the private key themselves, so we introduced SecKeyProxy.  Now, all those things work and we don't
        serialize SecIdentityRefs any more, so let's remove the problematic dead code that would have tried.
        Luckily, we now have API tests that verify that client certificate authentication still works.

        r169938 added a restriction to looking in the keychain only if the parent app has entitlements needed to do so.
        That restriction isn't needed any more because nobody looks in the keychain from the network process.

        r269162 entirely removed looking in the keychain for private keys for client certificate authentication.
        This is moving in that same direction.

        [Concurrent display lists] Add an initial implementation of concurrent display list rendering
        https://bugs.webkit.org/show_bug.cgi?id=218426
        <rdar://problem/71167220>

        Reviewed by Ryosuke Niwa.

        This patch adds a first-cut implementation of concurrent display list rendering, which allows the GPU and web
        processes to read and write display list data at the same time. To achieve this, we remove the placeholder
        shared memory display list encoding mechanism previously added in <webkit.org/b/218406>, and replace it with a
        new model in which a writer (i.e. the web process) and a reader (i.e. the GPU process) share a set of reusable
        shared memory buffers which contain display list item data. As the writer appends data to shared memory, it
        increments a counter in each shared memory buffer that represents the number of bytes that the reader has yet to
        read; as the reader reads display list items from shared memory, it decrements this counter.

        This patch also implements a simple strategy for reusing these shared item buffers. The web process maintains a
        queue of reusable buffers; when display list items are appended and the current writable buffer is out of
        capacity, the display list item buffer calls out to WebKit2 via a client method to request more shared memory.
        Here, the web process traverses the queue of reusable item buffers in search of a buffer with sufficient
        capacity; if found, we hand this back to WebCore as an opaque `ItemBufferHandle`; otherwise, we allocate a new
        reusable shared memory buffer. Item buffers that have been used become reusable only after they are (1) no
        longer being read from -- i.e., the counter value is 0, and (2) they are not actively being written to.
        Buffers that have been used are lazily reintroduced into the reuse queue when a display list requests a handle
        to writable item buffer data.

        See below for more details.

        Add a new helper class to represent a shared display list item buffer that the GPU process can use to consume
        display list items. Advancing the cursor in `DisplayListReaderHandle` decrements the "remaining bytes" counter;
        the class also has a helper method for creating a new `DisplayList` with a given offset into the shared buffer,
        as well the number of bytes to read.

        This is the main loop in the GPU process that is responsible for applying incoming display list item data. This
        IPC endpoint receives information about where to start (i.e. an item buffer ID and an offset into shared memory
        in that buffer) and begins reading ranges of display list item data inside that buffer. After it is done
        processing all of its unread bytes, it then checks the unread byte count once again, and continues the loop if
        the web process has advanced this count.

        (WebKit::RemoteRenderingBackend::setNextItemBufferToRead):
        (WebKit::RemoteRenderingBackend::didCreateSharedDisplayListHandle):

        Add logic to handle the case where we reached the end of an item buffer, but the next buffer identifier is still
        unknown to us (since it is still "in transit" via the `DidCreateSharedDisplayListHandle` IPC message). In this
        case, we remember the next buffer identifier in `m_nextItemBufferToRead`, and exit the processing loop inside
        `wakeUpAndApplyDisplayList`. Upon receiving the shared memory handle in `didCreateSharedDisplayListHandle`, we
        then automatically resume display list processing, starting from the beginning of this new buffer.

        Repurpose `SharedDisplayListHandle` to serve as a base class for both `DisplayListReaderHandle` and
        `DisplayListWriterHandle`. This base class is aware of the memory layout of the display list item buffer in
        shared memory (in particular, the fact that the first 8 bytes are the atomic lock and the next 8 bytes contain
        the unread byte counter).

        Internally, this uses a protected RAII class, `SharedDisplayListHandle::Lock`, to grab the lock before either
        reading or writing the unread bytes count.

        Similar to `DisplayListReaderHandle`, except that this contains logic specific to the web process for writing
        display list items into shared memory. Advancing the cursor in `DisplayListWriterHandle` increments the counter.
        It also increments the `writableOffset` of the handle, which represents the minimum offset into the shared
        buffer that may contain newly appended display list items.

        (WebKit::RemoteRenderingBackendProxy::updateReusableHandles):

        This private helper iterates the set of buffers that are not currently being written to, and adds each one to
        the reusable buffer queue only if its writable offset is at the start.

        (WebKit::RemoteRenderingBackendProxy::createItemBuffer):

        Implements logic that hands shared item buffer data handles to WebCore for writing display list items. This will
        try to reuse an item buffer in the reuse queue, if possible, and fall back to allocating a new chunk of shared
        memory if no reusable buffer is found (or the existing buffers have insufficient capacity). The fact that we
        iterate through each reusable buffer in order, combined with the above logic in `updateReusableHandles`, ensures
        that once we begin writing to a item buffer, we will continue using that item buffer until it exhausts available
        capacity.

        This property is important because it allows the GPU process to simply start reading item data from a given
        offset and buffer ID (specified in the `WakeUpAndApplyDisplayList` IPC message), and seamlessly continue
        reading data even after it exhausts all available item data in the current buffer by continuing from the start
        of the item buffer that contains the next display list items (which we learn in the GPU process by encountering
        a `MetaCommandSwitchTo` item at the end of the previous buffer).

        In "steady state" (wherein both processes are concurrently writing and reading items as quickly as possible),
        this means that as the web process is busy filling up each item buffer with item data, the GPU process is also
        busy applying all the item data in one buffer and automatically moving on to the next buffer with no additional
        IPC messages required.

        GPUProcess does not properly get relaunched after crashing
        https://bugs.webkit.org/show_bug.cgi?id=218769

        Reviewed by Tim Horton.

        After the GPUProcess crashes, we need to make sure we construct a new GPUProcessProxy
        so that a new process gets relaunched. Previously, this wasn't possible because
        the GPUProcessProxy was a "never destroyed" singleton.

        The GPUProcessProxy is now kept alive by the WebProcessPool objects refing it.
        Upon crashing, all WebProcessPools clear their GPUProcessProxy RefPtr so that the
        old GPUProcessProxy gets destroyed. The next time a GPUProcessProxy is needed, a new
        one gets constructed. We still make sure that all WebProcessPool objects share the
        same GPUProcessProxy, as before this patch.

        Reviewed by Eric Carlson.

        RemoteAudioDestinationProxy::requestBuffer() was calling AudioDestinationCocoa::render()
        and expecting RemoteAudioDestinationProxy::renderOnRenderingThead() to get called as
        a result. It would take care of writing to the CARingBuffer and sending the IPC back
        to the GPU process in renderOnRenderingThead(). The issue was that AudioDestinationCocoa
        uses a PushPullFIFO internally for buffering. It first fetches available frames from
        the FIFO and then only calls renderOnRenderingThead() with the number of frames that
        remain to processed (usually 0). As a result, RemoteAudioDestinationProxy::renderOnRenderingThead()
        would often store 0 frames instead of 128 (or sometimes a number of frames less than
        128), even though the full 128 frames were actually rendered.

        To address the issue, stop overriding renderOnRenderingThead() in
        RemoteAudioDestinationProxy. Instead, do the writing to the CARingBuffer and the IPC
        response in RemoteAudioDestinationProxy::requestBuffer(), directly after calling
        AudioDestinationCocoa::render(). After calling AudioDestinationCocoa::render()
        we know that |framesToRender| frames have been rendered / added to the buffer.

        Fix crashes when mapping shared display list item data into display lists in the GPU process
        https://bugs.webkit.org/show_bug.cgi?id=218739

        Reviewed by Tim Horton.

        I added a "stop-gap" mechanism in r269525 to allow the GPU process to handle newly refactored display list
        items by encoding display list items directly into shared memory buffers in the web process and reading them
        back in the GPU process, using standard IPC messages only, and also without reusing any shared memory buffers.

        However, I introduced a bug in this "stop-gap" mechanism when I tried to clean up some GPU-process-side logic
        for unregistering these shared memory buffers in the GPU process, by taking shared memory buffers out of the
        map in the GPU process without ensuring that they're kept alive over the course of applying the display list.

        This code is going away soon anyways (see webkit.org/b/218426), but in the meantime, we should at least ensure
        that this temporary shared memory mechanism doesn't cause huge waves of layout test failures.

        https://bugs.webkit.org/show_bug.cgi?id=218329

        Reviewed by Carlos Garcia Campos.

        ScrollGestureController's purpose is to handle otherwise-unhandled
        touch events and translate those into a scrolling gesture.

        Until now, it was possible for a touch motion event to trigger that
        gesture even when the corresponding touch down event was not handled
        by the ScrollGestureController, e.g. it was not produced due to the
        touch interaction being started somewhere else, or the Web content
        actually handled that event.

        A flag is added to ScrollGestureController to track that an unhandled
        touch down event was confronted, before allowing subsequent unhandled
        touch motion events to trigger the scrolling gesture when conditions
        are met. The flag is reset upon the touch up event.

        PiP return to element full screen is not smooth on some websites
        https://bugs.webkit.org/show_bug.cgi?id=218419

        Reviewed by Jer Noble.

        In r265562, VideoFullscreenInterfaceAVKit uses `fullscreenMayReturnToInline()`
        to request the observer (WKFullScreenWindowController) to enter element fullscreen
        before exiting picture-in-picture, and calls `fullscreenWillReturnToInline()` to
        proceed returning to inline or element fullscreen after WKFullScreenWindowController
        is ready.

        In this patch, VideoFullscreenInterfaceAVKit will directly enter a temporary
        video fullscreen from picture-in-picture, so the preparation step (entering element
        fullscreen) is not needed.

        Some important points regarding edge cases:
        1) A video enters picture-in-picture and exits picture-in-picture immediately
        before WKFullScreenWindowController is notified to exit element fullscreen.
        In this case, WKFullScreenWindowController will do nothing when it is notified
        that the video has exited picture-in-picture. It will directly tell
        VideoFullscreenInterfaceAVKit to enter standby.

        2) A video exits picture-in-picture when WKFullScreenWindowController is exiting
        element fullscreen but not complete yet. In this case, WKFullScreenWindowController
        needs to hold the enter element fullscreen request and exits element fullscreen
        first before entering element fullscreen.

        3) The ancestor element of the video element exits fullscreen and asks the video
        element to exit standby (in web process) while the video is entering picture-in-picture
        (in UI process). In this case, VideoFullscreenInterfaceAVKit (in UI process) should
        ignore the request to exit standby and tell the web process the request is rejected.

        4) A user may try to enter picture-in-picture when the video is exiting picture-in-picture
        and returning to element fullscreen. In this case, VideoFullscreenInterfaceAVKit
        (in UI process) should temporarily disable the picture-in-picture support.

        [macOS] Align left edge of presented calendar with left edge of date inputs
        https://bugs.webkit.org/show_bug.cgi?id=218668

        Reviewed by Tim Horton.

        When a date input is activated, a calendar is presented by adding an
        NSWindow containing an NSDatePicker to the screen. The frame of the
        window is set to ensure proper alignment with the date input. However,
        since the window's hasShadow is set to true, AppKit draws a thin border
        and shadow around the window's contentView. This results in left border
        of the window being drawn further out than the left border of the input
        itself. If the hasShadow property is set to false, the issue is no longer
        observed, and the calendar aligns with the input. However, this is not an
        acceptable solution, since we lose the border and the shadow.

        To ensure alignment between the border of the calendar view and the border
        of the date input, we can inset the edges of the view. Note that the inset
        is not applied along the y-axis, to avoid a gap between the bottom of the
        date input and the top of the calendar view.

        The argument coder for `WebCore::ImageData` currently sends its image data by allocating a separate shared

        with the new "concurrent display list" model for processing display list items, wherein all out-of-line items
        are encoded as raw bytes directly into reusable shared memory buffers and decoded from the corresponding buffer
        in the GPU process.

        Instead, encode and decode image data directly into and out of the main IPC data buffer. This also addresses a
        couple of existing FIXMEs in the ImageData coder methods by avoiding the need for redundant copies to and from

        does not attempt to make any reading or writing in shared memory concurrent between the GPU and web processes,
        and exists only to make sure that rendering with the GPU process still works using these new display list items.

        wpe_loader_init() tries to dlopen a development symlink, but these will not usually be
        installed. It only works in the GNOME flatpak runtime because we don't use devel split
        rules in the GNOME runtime, but we really ought to, and freedesktop-sdk already does, so
        it's going to break upstream too once that gets implemented. It's easier for everyone if
        we tackle this now. Since all major distros except Arch Linux use devel split, this patch
        is really required for almost every distro to use WPE renderer.

        The downside is that this makes it harder to update the wpebackend-fdo library version,
        since minor changes there will now unnecessarily break WebKit. This is not good, but it's
        better than forcing distros to apply this same patch downstream. I considered trying a bunch
        of different library versions in a loop in order to maximize the chance of success in case
        the wpebackend-fdo library version increases in the future, but it's probably nicer to just
        be careful about not changing its library version until we find a better solution for this.

        When a DrawImageBuffer item is appended to DisplayList, a Ref<ImageBuffer>
        will be cached till the DisplayList items list is cleared. So no need to
        lock the remote resource in RemoteResourceCacheProxy.

        All we need to is to pass the ImageBufferHashMap which is maintained by
        the DisplayList or by RemoteResourceCache to the DisplayList::Replayer.
        It is going to be used to resolve the RenderingResourceIdentifer to an
        ImageBuffer so the DrawImageBuffer can be applied.

        No need to special-case DrawImageBuffer::apply() in the RemoteImageBuffer.

        When the script calls suspend(), we call AudioDestinationCocoa::stop() to stop rendering and then resolve the suspend promise.
        At this point, the script saves the AudioContext's current sample frame and expects this value to not change until the
        AudioContext is resumed. The issue was that we previously were potentially resolving the promise on the main thread while
        the last rendering quantum was still being processed on the AudioWorklet thread. This meant that the sample frame could
        still increase a bit, a short while after the suspend promise has been resolved. To address the issue, we now to a round
        trip to the AudioWorklet thread after stopping rendering, to make sure we only resolve the promise after the last rendering
        quantum has been processed on the AudioWorklet thread.

        Reviewed by Simon Fraser.

        Currently after a remote ImageBuffer is deleted, its identifier is locked
        in the RemoteResourceCacheProxy till no remote client is referencing it.
        Then an IPC message is sent to GPU Process to release it.

        The plan is to decode the DisplayList::DrawImageBuffer by replacing the
        ImageBuffer identifier with a RefPtr to the ImageBuffer itself. Once the 
        ImageBuffer is removed from the RemoteResourceCache, it is going to be
        deleted after the last DrawImageBuffer is replayed back. So no locking 
        is needed to guarantee the existence of the ImageBuffer when it is drawn.

        [iOS] Link Contacts.framework during build

        <rdar://problem/70770410>

        Reviewed by Andy Estes.

        Contacts.framework is currrently soft linked in PaymentAuthorizationPresenter.
        Soft linking is generally discouraged, since it requires running the linker
        at runtime, leading to an unwanted performance cost. By normally linking
        the framework, the linkage is declared at build time, which enables running
        the linker at build/update/install time and avoiding the runtime cost.

        Unfortunately, we still have to soft link the framework on macOS, to avoid
        introducing a dependency cycle. Upward linking is not an option, since the
        Contacts framework does not implement InstallAPI.

        The SOFT_LINK_FRAMEWORK macro has been kept in PaymentAuthorizationPresenter
        to avoid introducing additional #ifs. This should be fine to keep on iOS,
        since the framework will already loaded in the address space, and the call
        to dlopen() should be much less expensive.

        Crash under ProcessThrottler::setAssertionType()
        https://bugs.webkit.org/show_bug.cgi?id=218448
        <rdar://problem/67419221>

        Reviewed by Geoffrey Garen.

        A ProcessThrottler object is owned by its associated AuxiliaryProcessProxy. The crash was happening
        in ProcessThrottler::setAssertionType(), we would replace m_assertion with a new "Suspended"
        assertion and then crash on the next line when using m_assertion. The reason we crash is that
        when we replaced m_assertion with a new assertion, the destruction of the previous assertion
        caused the UIProcess's background task to get released (because this was the last non-suspended
        process assertion). When we release the UIProcess' background task, we call
        WebProcessPool::notifyProcessPoolsApplicationIsAboutToSuspend(), which destroys non-critical
        WebProcesses (e.g. WebProcesses in the back/forward cache), which in turns destroy their
        ProcessThrottler. As a result, when replacing m_assertion, the ProcessAssertion may get
        destroyed, which is why we would crash on the next line when trying to use m_assertion.

        To address the issue, we now release the UIProcess's background task asynchronously when
        releasing the last non-suspended ProcessAssertion, making sure we still need to release
        the assertion beforehand. This has 2 benefits:
        - The ProcessThrottler can no longer get destroyed synchronously when releasing its
          ProcessAssertion.
        - In the case where the ProcessThrottler replaces a foreground assertion with a background
          assertion (or vice-versa) and this is the last non-suspended assertion, this avoids
          unnecessarily releasing and retaking the UIProcess's background task. This also avoids
          killing non-critical processes unnecessarily.

        We doing the process swap at step 3, we would suspend the page containing A#foo

        for A#foo to remain in process, as we may want it for another back/forward
        navigation later.

        The issue was that when constructing the new WebPage in P1 for A at step 4,
        we would restore all history items from the WebPageProxy's BackForwardList
        and overwrite any existing HistoryItems with the same IDs in the WebProcess.
        This meant that WebKit layer would construct new HistoryItems for
        HistoryItems that already existing and are used by the Suspended WebPage
        containing A#foo.

        Later on, at step 6, when trying to go back A#foo in P1, we would ask
        the Suspended WebPage in P1 to load a given HistoryItem. This HistoryItem
        is supposed to be present in the Page's back/forward list and is supposed
        to have an associated back/forward cache entry. However, it was not the
        case here because we ended up with a new HistoryItem instance that was
        restored from the UIProcess earlier.

        To address the issue, The WebPage constructor no longer overwrites
        existing HistoryItems. Note that before prior to r231048, the WebPage
        constructor was NOT overwriting existing HistoryItems so this restores
        previous behavior. Presumably, we started overwriting to stop hitting
        the assertion in WebBackForwardListProxy::addItemFromUIProcess() that
        checked that we either wanted to overwrite or that there was no
        existing HistoryItem with the given ID. This is no longer an issue
        since I replaced this assertion with an if-check and an early return.

        Often, based on a race condition of preconnecting to a server we have just been told to load and
        the use of Safari's BackgroundLoad class when navigating to a page we have not received any data from yet,
        and with an installed client certificate and an identity preference in the keychain, the user will be asked
        if com.apple.WebKit.Networking can access a private key in the keychain instead of if Safari can access a
        private key in the keychain.  If the user types in the password and clicks "Always Allow" this does not make
        it always allowed, but it would have if Safari had asked instead of com.apple.WebKit.Networking.
        This is because Safari is responding to WKNavigationDelegate's didReceiveAuthenticationChallenge with
        NSURLSessionAuthChallengeUseCredential and nil, which would cause CFNetwork to search in the keychain as the network
        process for the preferred client certificate.  What we want Safari's network process to do is not search in the keychain
        for this preconnect request's challenge but wait until the actual request, at which time Safari will use its proper logic
        to find the correct client certificate and AuthenticationManager::initializeConnection will create a SecKeyProxy
        to do the signing in the UI process.  Third party applications will not be affected because the SecKeyProxy path is the
        only one that works for applications lacking Safari's entitlements.  I used the steps in the radar to verify that this
        is fixed.  Unfortunately, it is not practical to make a unit test that installs a system client certificate and an
        identity preference because doing so would require the entry of the login keychain password while running the unit test.

        <rdar://problem/70355910>

        Reviewed by Devin Rousso.

        Introduce _WKInspectorConfiguration for customizing the behavior of Web Inspector instances.
        The initial customization is to allow for custom WKURLSchemeHandlers to be used by Web Inspector's
        WebView to load resources from client-controlled locations. This can be used to implement loading
        of extension resources using a custom scheme such as web-extension://.

        Scheme handlers need to be registered at WebView creation time via WKWebViewConfiguration. In
        order to configure a inspector page summoned from within WebKit (i.e., Inspect Element context menu item),
        we need to add a method to the UI delegate to get a configuration when the page is being created.

        This configuration object is used in two different SPI (local and remote cases):

        - As part of WKUIDelegatePrivate, to retrieve a _WKInspectorConfiguration given a _WKInspector.
        - As an argument to the _WKRemoteWebInspectorViewController initializer. It's used later as needed.

        [GPU Process]: Implement DisplayList::DrawImageBuffer item
        https://bugs.webkit.org/show_bug.cgi?id=217566

        Reviewed by Simon Fraser.

        The sequence in the Web Process is the following:

        -- GraphicsContext::drawImageBuffer() uses DisplayList::Recorder to check
           whether it is appropriate to create a DrawImageBuffer item or not.

        -- DisplayList::Recorder::drawImageBuffer() uses the delegate to see if
           the ImageBuffer is remote or not and whether it can be locked till 
           replaying back the DisplayList in the GPU side. 

        -- RemoteImageBufferProxy inherits DisplayList::Recorder::Delegate. So
           its lockRemoteImageBuffer() is called.

        -- If the ImageBuffer can be locked, a DrawImageBufferItem is created with
           the ImageBuffer::renderingResourceIdentifier().

        The sequence in the GPU Process is the following:

        -- When replaying back the DisplayList, DisplayList::Replayer will call
           its delegate to check if it wants to apply the DrawImageBuffer.

        -- Because RemoteImageBuffer inherits DisplayList::Replayer::Delegate,
           RemoteImageBuffer::apply() will be called.

        -- RemoteImageBuffer will call RemoteRenderingBackend::applyResourceItem()
           which will check whether the item's renderingResourceIdentifier is one
           of the ImageBuffers in its RemoteResourceCache or not.

        -- If there is a cached ImageBuffer, RemoteRenderingBackend::applyResourceItem()
           will draw it in the GraphicsContext.

        This is documented in WKNavigationDelegate.h, and the behavior is basically identical.
        The difference is if there is a challenge with multiple protection spaces and a delegate that implements didReceiveAuthenticationChallenge
        is attached between the delegate callbacks, it will receive the second callback.  This is unlikely and next to impossible to test, but
        out of principle we should behave like we have documented that we do.

        [GPU Process]: Introduce RemoteResourceCacheProxy to manage the remote resources in Web Process
        https://bugs.webkit.org/show_bug.cgi?id=217558

        Reviewed by Simon Fraser.

        Remove RemoteImageBufferMessageHandlerProxy and move sending the messages
        to RemoteRenderingBackendProxy.

        To allow casting ImageBuffer to RemoteImageBufferProxy, a new method named
        remoteResourceIdentifier() is added to IamgeBuffer and it is only overridden
        by RemoteImageBufferProxy. This method is used in SPECIALIZE_TYPE_TRAITS
        macros along with IamgeBuffer::isAccelerated().

        Introduce RemoteResourceCacheProxy which will manage caching and releasing
        the RemoteImageBufferProxy. Caching NativeImage will be added to it in
        future patches. More about controlling the life cycles of remote resources 
        will be added also when supporting drawing remote resources to remote client
        in future patches.

        this, we just need to disconnect the signal when required. Normally that would be done in
        the destructor, but the WebSocketTask drops its ownership of the SoupMessage prior to that

        [iOS] Prevent presentation of input peripherals when focusing form controls with a validation message
        https://bugs.webkit.org/show_bug.cgi?id=218004
        <rdar://problem/70507678>

        Reviewed by Wenson Hsieh.

        Interactive form validation can result in the presentation of a
        validation message bubble near the first form control that has invalid
        data. Prior to displaying the message, the invalid control is focused.
        On iOS, this also has the effect of also presenting a virtual keyboard
        or another custom input peripheral, such as a context menu for date
        inputs.

        Attempting to present both the validation message and custom input
        peripheral can leave the view in an inconsistent state. For example,
        <select> popovers have a strange flashing behavior when presented
        alongside a validation message, and context menus can fail to present
        entirely.

        In order to address these issues, we should never attempt to present
        both a validation message and an input peripheral. Instead, we can
        prevent the presentation of input peripherals when the focused control
        is presenting a validation message. This behavior matches macOS. Note
        that we still present the keyboard for controls that have a keyboard
        view, since the keyboard area does overlap the area where a validation
        message is presented.

        [Media in GPU Process] Some WebAudio layout tests generate strange noises
        https://bugs.webkit.org/show_bug.cgi?id=217921

        Reviewed by Eric Carlson.

        RemoteAudioDestination::render() should not return `noErr` unless we can provide the requested
        samples to the provided AudioBufferList. Otherwise, the audio output unit of CoreAudio will output
        the samples in the AudioBufferList, which might be invalid data at the beginning of a rendering.
        We have observed that happens in some layout tests and some WebAudio example pages.

        Currently, RemoteAudioDestination::render() always returns `noErr` in the render thread (immediately),
        but the AudioBufferList (ioData) is updated in the main thread (later). This patch fixes that by only
        setting the bounds of CARingBuffer in the completion handler of sendWithAsyncReply() in the main thread,
        and fetching AudioBuffer(s) from the CARingBuffer in the render thread. Also, RemoteAudioDestination
        tracks the progress of fetching, so RemoteAudioDestinationProxy does not need to send `startFrame`
        and `numberOfFramesToRender` to RemoteAudioDestination in response to a buffer request.

        RemoteAudioDestination::render() should not need to dispatch to the main thread to do IPC as this is bad
        for performance and IPC::Connection::sendWithAsyncReply() already does locking internally for thread-safety.
        The only thing that was preventing us from calling sendWithAsyncReply() from the audio rendering thread was
        a threading assertion in CompletionHandler that made sure that the completion handler was always called on
        the thread the completion handler was constructed on. To avoid this issue, I added a paramater to the
        CompletionHandler constructor allowing the caller to indicate it expects the completion handler to get called
        on the main thread. I am now using this new flag in sendWithAsyncReply() and at its call site in
        RemoteAudioDestination::render().

        No new tests, no Web-facing behavior change.

        Rename flushDrawingContext() to flushDisplayList() because the name is 
        confusing. This function flushes a DisplayList to the context. No
        DrawingContext is involved here and there is another function with the

        [Media in GPU Process] Use CARingBuffer to transfer audio data of an audio destination from a web process to the GPU Process
        https://bugs.webkit.org/show_bug.cgi?id=217715

        Reviewed by Jer Noble.

        The current implementation of RemoteAudioDestination essentially runs the
        AudioDestinationCocoa in the GPU process, which is not good because we are adding
        AudioWorklet stuff into AudioDestinationCocoa, but the AudioWorklet stuff is
        irrelevant to the GPU process.

        What really needs to run in the GPU process (for Cocoa platforms at least) is the
        audio output unit. This patch adds WebCore::AudioOutputUnitAdaptor and
        WebCore::AudioUnitRenderer to implement that. With this patch, RemoteAudioDestination
        in the GPU process is an AudioUnitRenderer and it embeds an AudioOutputUnitAdaptor
        like AudioDestinationCocoa does in the Web process. Essentially, we run AudioOutputUnitAdaptor
        remotely from the AudioDestinationCocoa's perspective.

        Also, in the current implementation, the RemoteAudioDestinationProxy in a Web
        process transfers audio data to the RemoteAudioDestination in the GPU process
        with IPC messages (RemoteAudioBusData). This is not efficient because of the
        large number of IPC messages for audio samples.

        With this patch, RemoteAudioDestinationProxy (Web process) transfers audio samples
        to RemoteAudioDestination(GPU process) with a CARingBuffer providing shared
        buffers for the Web process and the GPU process.

        <rdar://problem/70168749>

        Reviewed by Brent Fulgham.

        Previous patch r268248 introduces a new daemon to handle all WebAuthn requests. However, after more deeper investigations, the daemon
        story is not very compelling for WebKit. Here are the two major road blockers:
        1) The major one is on macOS. New daemons cannot be installed without a system update. It means relocatable Safari (e.g. STP)
        and staged Safari on downlevel OSes will not get this feature. And relocatable STP can only utilize the system daemon. This
        seems a bummer especially for the STP case given it is heavily used to test latest web features.
        2) Additional plumbing is needed for testing and engineering builds. This problem is specific to WebKit and is on both macOS and iOS.
        WebKit doesn't build roots to test engineering builds, which is required to update the plist on the above location. Hence, a separate
        configuration is needed to generate a different plist that points to the right engineering binary and additional scripts will be needed
        to ask launchd to load the plist before running any tests. Some extra exercises are probably needed to not confuse launchd about the
        engineering binary and system binary as well.

        Given the above constraints, a new architecture is proposed to make the daemon a WebKit XPC service/process instead and leave the launchd
        event handler to a new Safari daemon. The launchd related feature is only on iOS and therefore it really doesn't make sense to overcome
        all the above macOS constraints. Having different architectures on iOS (a daemon) and on macOS (a XPC service) accordingly will introduce
        tons of overhead for maintainance as well. That's why relying on a Safari daemon to do the job is the most reasonable option.

        This patch therefore focuses on making the WebAuthn process happen and removes the WebAuthn daemon.

        IPC testing JS API should expose a reply and describe the list of arguments for each message
        https://bugs.webkit.org/show_bug.cgi?id=217565

        Reviewed by Geoffrey Garen.

        This patch makes IPC.sendMessage and IPC.sendSyncMessage decode the reply. IPC.sendSyncMessage now returns
        a dictionary with two keys: "buffer" and "arguments", the first of which returns ArrayBuffer of the decoded
        message reply and the second of which is an array of decoded arguments where there was an appropriate JS
        binding code existed for the argument type. IPC.sendMessage now returns a Promise which can either resolve
        with the same dictionary as IPC.sendSyncMessage or reject when the decoding fails.

        In addition, this patch exposes a dictionary describing each IPC message argument's type and parameter name.

        In order to add these two functionalities, this patch adds a new step in generate-message-receiver.py to
        generate MessageArgumentDescriptions.cpp, which contains functions which know how to decode arguments of
        any IPC message and create a JS dictionary describing it as well as functions that return descriptions of
        arguments or reply arguments.

        Finally, this patch adds encoders for a few types found to be very common after r268239 had been landed.

        REGRESSION(r268423) SHOULD NEVER BE REACHED: GPUConnectionToWebProcess::didReceiveMessage(IPC::Connection &, IPC::Decoder &)
        https://bugs.webkit.org/show_bug.cgi?id=217730
        <rdar://problem/70308112>

        Reviewed by Geoffrey Garen.

        r268423 added support for registering IPC WorkQueueMessageReceivers & ThreadMessageReceivers with
        a given identifier. When receiving an IPC message, we would look up the key [ReceiverName, ID] in
        the receiver map and pass the message to this receiver.
        This introduced a crash because of an existing ThreadMessageReceiver (RemoteAudioMediaStreamTrackRenderer)
        was registering itself as a message receiver without an identifier (ID=0). However, the IPC senders
        on GPU process side would pass a non-0 identifier when sending the IPC. As a result, we would fail to
        look up the receiver in the map when receiving those IPC messages.

        While existing code should probably be fixed so that senders and receivers agree on on identifier,
        I have decided to fix the issue in this patch at IPC::Connection level. When receiving an IPC
        message, we first check if there is a "global" receiver in the map by looking up key
        [ReceiverName, 0]. If there is, we pass the IPC to this one. If there isn't, we look up the key
        [ReceiverName, ID] in the map and use the more specific receiver.

        The reason I chose to fix it this way is that the code in MessageReceiverMap (which is used for
        receivers that are not using a WorkQueue or a Thread) behaves in this fashion. I believe it is
        good to have consistency between all kinds of receivers.

        No new tests, covered by existing test that is crashing on the bots.

        The UI process will enqueue wheel events to send later if the WebContent process doesn't
        promptly respond that it has handled the previous event. When scrolling in the passive
        event region, we want the WebContent process to appear responsive, so respond to the UI
        process when we've scrolled (which is before the event has been dispatched for DOM events).

        Hard to test because CPU-constrained bots don't send wheel events in a predictable way.

        IPC testing JS API should expose a reply and describe the list of arguments for each message
        https://bugs.webkit.org/show_bug.cgi?id=217565

        Reviewed by Geoffrey Garen.

        This patch makes IPC.sendMessage and IPC.sendSyncMessage decode the reply. IPC.sendSyncMessage now returns
        a dictionary with two keys: "buffer" and "arguments", the first of which returns ArrayBuffer of the decoded
        message reply and the second of which is an array of decoded arguments where there was an appropriate JS
        binding code existed for the argument type. IPC.sendMessage now returns a Promise which can either resolve
        with the same dictionary as IPC.sendSyncMessage or reject when the decoding fails.

        In addition, this patch exposes a dictionary describing each IPC message argument's type and parameter name.

        In order to add these two functionalities, this patch adds a new step in generate-message-receiver.py to
        generate MessageArgumentDescriptions.cpp, which contains functions which know how to decode arguments of
        any IPC message and create a JS dictionary describing it as well as functions that return descriptions of
        arguments or reply arguments.

        Finally, this patch adds encoders for a few types found to be very common after r268239 had been landed.

        WebAudio tests are crashing in debug when enabling the GPU process
        https://bugs.webkit.org/show_bug.cgi?id=217663

        Reviewed by Geoff Garen.

        WebAudio tests were crashing in debug when enabling the GPU process because it did audio
        processing on the WebContent process's main thread. To address the issue, I made
        RemoteAudioDestinationProxy a ThreadMessageReceiver so that it receives IPC on an audio
        thread instead of the main thread. IPC messages are processed directly on the AudioWorklet
        thread when active or on an audio thread constructed by RemoteAudioDestinationProxy
        otherwise.

        * GPUProcess/media/RemoteAudioDestinationManager.cpp:
        (WebKit::RemoteAudioDestination::RemoteAudioDestination):
        Use a PushPullFIFO structure in render() to avoid hanging the audio rendering thread
        on a semaphore. Hanging the rendering thread was terrible for performance and was also
        a source of deadlock since the underlying framework is holding a lock while render() is
        called. We could process a RemoteAudioDestination::CreateAudioDestination sync IPC on the
        main thread and deadlock on that lock.

          The GPUProcess sends IPC messages to the RemoteAudioDestinationProxy with a given
          destinationID and since RemoteAudioDestinationProxy is now a ThreadMessageReceiver.
        - Stop having ThreadMessageReceiver subclass ThreadSafeRefCounted since
          RemoteAudioDestinationProxy already subclasses ThreadSafeRefCounted indirectly. A new
          ThreadMessageReceiverRefCounted class was added for convenience for existing code that

        Bug 42796 introduced MACOSX_DEPLOYMENT_TARGET_<PLATFORM> as "support
        for compiling WebKit against iOS SDKs". Support for the iOS part of
        this feature was later removed in several changes, including Bug
        139212, Bug 139463 and Bug 144762. However, vestiges have remained for
        five or six years in the form of MACOSX_DEPLOYMENT_TARGET_macosx. The
        inclusion of the platform in MACOSX_DEPLOYMENT_TARGET is no longer
        needed and can be removed.

        This changes brings most projects in conformance with other projects
        that don't support including the platform in MACOSX_DEPLOYMENT_TARGET,
        including WebEditingTester, gtest, WebKitTestRunner, MiniBrowser, and
        TestWebKitAPI.

        Along the way, remove a couple of left-over references to macOS 10.16,
        and a couple of places where [sdk=macosx*] was still being used.

        With this change, initialization of MACOSX_DEPLOYMENT_TARGET should be
        consistent across all projects, with two exceptions: WebKitLauncher
        (which hardcodes it to 10.12) and libwebrtc's copy of googletest
        (which hardcodes it to 10.4). The reasons for these hard-coded values
        is not apparent, so leave them be.

        Reviewed by Sam Weinig.
        
        WebPageProxy had some confusing code for coalescing wheel events, first added in r116466.
        To prepare this code for partial re-use in another place, factor it into its own class, WebWheelEventCoalescer.

        WebWheelEventCoalescer holds a queue of pending NativeWebWheelEvents, and a queue of sequences of
        NativeWebWheelEvents, where each sequence has been coalesced into a single WebWeelEvent which was
        sent to the Web Process.

        When the UI process receives a message back from the Web Process, it calls takeOldestEventBeingProcessed()
        which removes the first sequence from m_eventsBeingProcessed. This code has to track NativeWebWheelEvents, because
        we need to dig the NSEvent out of the NativeWebWheelEvent at this stage.

        This paves the way for a good download API that has a completion handler when you call cancel that gives you the resume data if it can.
        Currently you have to call cancel on the download, wait for didCancel on the delegate, then get the resume data from the download again.
        This has the side effect of DownloadMonitor cancellations calling didFailWithError instead of didCancel, which makes sense and shouldn't
        cause any problems in practice.  Safari is the only API client that uses this, and it behaves similarly in didCancel and didFailWithError.

        Reviewed by Darin Adler.

        Part 1.

        This patch introduces a new dummy WebAuthenticationAgent where in the future it will take over all WebAuthn operations
        from the UI Process such that we can isolate high privileged entitlements to this standalone daemon and therefore are able
        offer WebAuthn to third party WKWebView clients. One of the future feautres will require this new process to listen to
        LaunchEvents, which only daemons can do. That's why it is implemented as a user agent instead of a XPC service.

        This is the first part of establishing such a dummy daemon. What it does is to set up a new build target for the daemon and
        hook it up with WebKit's build system. One can manually load the launchd plist and load the daemon to verify this change.

        Commands are:
        launchctl load /to/your/path/com.apple.webkit.WebAuthenticationAgent.plist
        launchctl start com.apple.webkit.WebAuthenticationAgent.Development

        Covered by manual tests.

        This patch introduces the JavaScript API (window.IPC) to send IPC out of WebContent process.
        The feature is compiled in under ASAN and Debug builds and can be enabled at runtime.

        window.IPC has two methods: sendMessage and sendSyncMessage which sends an async and sync IPC respectively.
        It takes the destination process name (UI, GPU, or Networking), the destination ID (e.g. WebPageProxy ID),
        message ID, timeout for sendSyncMessage, and optionally IPC message arguments. The message arguments can be
        passed in as a TypedArray or ArrayBuffer, or a JavaScript array that recursively describes encoded objects.

        Each object can be either a TypedArray or ArrayBuffer, which will be treated as encoded message, an array
        which will be encoded as a Vector with each item within the array encoded recursively, or a dictionary which
        describes a specific type.

        When a specific type is described via a dictionary, "value" is encoed based on "type" as follows:
         - When "type" is "String", "value" is encoded as a WTF::String, treating null or undefined as a null string.
         - When "type" is "bool", "int8_t", "int16_t", "int32_t", "int64_t", "uint8_t", "uint16_t", "uint32_t",
           or "uint64_t", "value" (which can be BigInt or a number) is encoded as the respective C++ type.
         - When "type" is "RGBA", "value" is used as PackedColor::RGBA to construct WebCore::Color to be encoded.
         - When "type" is "IntRect" or "FloatRect", "x", "y", "width", and "height" are treated as respective values
           of IntRect or FloatRect C++ objects, and the constructed *Rect is encoded. 
         - When "type" is "FrameInfoData", the context object's WebFrame's FrameInfoData is encoded.

        The list of IPC messages are exposed on window.IPC.messages, and VisitedLinkStore ID, WebPageProxy ID,
        and frame identifiers are also exposed as static variables on window.IPC.

        [iOS] Blurring a text input and focusing a date input changes the scrollable area
        https://bugs.webkit.org/show_bug.cgi?id=217325
        <rdar://problem/69979171>

        Reviewed by Wenson Hsieh.

        iOS 14 changed the presentation style of date/time pickers on iPhones.
        Previously, date/time pickers would show up in the keyboard view. Now,
        pickers are shown in UIContextMenus.

        When the change was made, shouldShowKeyboardForElement in WKContentViewInteraction
        was not updated to reflect the new behavior, and continued to return
        true for date/time inputs.

        This inaccuracy led to WKContentView ignoring the UIKeyboardWillHideNotification
        when blurring a text input and focusing a date input, since it assumed
        the keyboard would stay presented. Consequently, the UIScrollView
        adjustments made when presenting the keyboard for the text input are not
        reverted when presenting the date picker, leading to a permanent change
        in the scrollable area.

        To fix, update shouldShowKeyboardForElement to return false for date/time
        inputs. Note that the original patch which changed the behavior
        correctly updated [WKContentView requiresAccessoryView] but did not
        update shouldShowKeyboardForElement. To prevent a similar mistake from
        happening again, the logic which determines which input types have a
        keyboard view was moved into elementTypeRequiresAccessoryView.

        Replace unqualified use of PlatformDisplayID in WebViewImpl
        https://bugs.webkit.org/show_bug.cgi?id=217422

        Reviewed by Youenn Fablet.

        WebViewImpl utilizes things from WebCore but doesn't use the namespace, instead choosing to
        qualify each reference. However, there is one use of WebCore::PlatformDisplayID that
        doesn't use the the namespace qualifier. Usually this "works" because the code is in the
        WebKit namespace, and other files that get included above this one often contain code of
        the form

        namespace WebKit {
        using WebCore;
        // code
        }

        which hides the issue by making PlatformDisplayID visible to this file as well without the
        prefix. If we use auto none of this matters because it'll deduce the prefix even if
        WebViewImpl.mm ends up near the top of a unified source file, before another file with the
        using declaration shows up.

        Reviewed by Darin Adler.

        Under XCBuild, the scripts employed in custom build rules can be
        invoked in innocuous situations. A common example is when the user is
        building from the command-line and they change the `make` output from
        stdout to a file, or vice-versa. Changing the output changes the
        setting of the COLOR_DIAGNOSTICS environment variable, which is enough
        to cause XCBuild to think something is different and that the custom
        build rule needs to be invoked. For the script's part, nothing
        significant has changed, yet it post-processes the header files,
        causing their modification dates to change, causing downstream
        rebuilds to occur.

        Fix this problem by adopting an approach that doesn't modify the
        post-processed header files unless their contents actually change.

        No new tests -- this is a build change only.

        <rdar://problem/70012011>

        Reviewed by Darin Adler.

        Part 1.

        This patch introduces a new dummy WebAuthenticationAgent where in the future it will take over all WebAuthn operations
        from the UI Process such that we can isolate high privileged entitlements to this standalone daemon and therefore are able
        offer WebAuthn to third party WKWebView clients. One of the future feautres will require this new process to listen to
        LaunchEvents, which only daemons can do. That's why it is implemented as a user agent instead of a XPC service.

        This is the first part of establishing such a dummy daemon. What it does is to set up a new build target for the daemon and
        hook it up with WebKit's build system. One can manually load the launchd plist and load the daemon to verify this change.

        Commands are:
        launchctl load /to/your/path/com.apple.webkit.WebAuthenticationAgent.plist
        launchctl start com.apple.webkit.WebAuthenticationAgent.Development

        Covered by manual tests.

        The select element used in this instance uses a custom font (Open Sans)
        with a 16px font size. When presenting the select dropdown a call to
        WebPopupMenuProxyMac::showPopupMenu is made with those attributes.
        However, since Open Sans is not a system font, the call to
        [NSFont fontWithDescriptor:size:] returns nil. This results in the
        presented view falling back to the default font size, which is smaller
        than the expected 16px size, leading to smaller options.

        While other browsers do not honor custom fonts in their select dropdowns,
        they do honor the font size. Consequently, this dropdown appears
        different in Safari. To fix, ensure that the font size is always honored
        if the corresponding attribute is present.

        Reloading a view in its processTerminationHandler does not work reliably when using related views
        https://bugs.webkit.org/show_bug.cgi?id=217407

        Reviewed by Geoff Garen.

        Related web views share the same WebContent process. When this process crashes, we iterate over
        the list of WebPageProxy objects sharing this process and let them know that their process has
        crashed. This causes the WebPageProxy to reset its state (so that it is aware it no longer has
        a running process) and to notify the client application. Because we were notifying the client
        application synchronously, the client could trigger a load in the view synchronously while we
        are still iterating over the WebPageProxy objects. When triggering a load in a web view that
        has no running process, we normally relaunch one. However, in the case of related web views,
        the view uses its related webview's process, relaunching it if necessary. The 'relaunching
        if necessary' part was not reliably happening here because the related web view may not have
        been notified yet that its WebProcess has crashed (since we are still iterating over the
        pages to notify them).

        To address the issue, we now notify the client asynchronously of the process termination.

        CSS hover and "pointer: fine" media queries do not evaluate to true with iOS 13.4 mouse support

        Reviewed by Tim Horton.

        On iOS, the primary pointer will always be touch input, so the `hover`/`pointer` media query
        should never change. If a mouse is connected, however, `any-hover`/`any-pointer` should
        change as now there is at least one device that supports `hover`/`fine`. Note that in the
        case of `any-pointer` this means that both `coarse` and `fine` will apply. Catalyst assumes
        that there is always a mouse connected.

        Move ownership of DownloadClient from WebProcessPool to DownloadProxy

        Reviewed by Tim Horton.

        To keep binary compatibility, the WebProcessPool has a nullable DownloadClient that is used if it has been set.
        This will allow us to get a DownloadClient from elsewhere, such as having the API Download object have its own delegate
        or having the WKWebsiteDataStore have a delegate, which are two of the solutions I've considered.  We definitely don't
        want it on the WebProcessPool, though.

        Before the ATK::Bridge target got introduced in r267399 a couple of CMake variables were

        added to the WebKit and WPEToolingBackends targets. Now that an imported target is used
        it is needed to add it as a dependency conditionally to avoid using an undefined target

        Clean up "rendering update" terminology in DrawingArea
        https://bugs.webkit.org/show_bug.cgi?id=217307

        Reviewed by Tim Horton.

        DrawingArea doesn't know about "immediate" vs. "normal" rendering updates; for it,
        all requests are for immediate rendering updates; the only difference is whether
        layer tree freezing is respected.

        This is the first step to correcting the naming; scheduleImmediateRenderingUpdate()
        doesn't have to be exposed at all. A future patch will rename DrawingArea::scheduleRenderingUpdate()
        to make it clear that it's not about timed updates.

        [Cocoa] Add WKUIDelegate SPI to inform clients when a _WKInspector is about to close

        Reviewed by Timothy Hatcher and Devin Rousso.

        This is complementary to _webView:didAttachLocalInspector: and works similarly.
        Clients need to be careful in depending on this during teardown, because it won't
        come if the UIDelegate has already been cleared out while the inspected page is being closed.

        https://bugs.webkit.org/show_bug.cgi?id=217236

        Reviewed by Eric Carlson.

        We disabled setting the audio session category in the Web process when media is playing
        in the GPU Process (r257367). But since RemoteAudioSession and RemoteAudioSessionProxy
        are working now in the Web process and GPU process, we need to allow setting the audio
        session category in the Web process.

        This patch also includes an optimization to reduce the IPC traffic of the audio session
        category changes.

        Refactor logic that removes drop placeholder attributes such that it runs as an asynchronously task rather than
        underneath the scope of `didFinishLoadingImageForElement`. This is because the image load client call may occur
        in the middle of a rendering update, during which it is not safe to change element attribute values, since that

        Reviewed by Eric Carlson.

        Even after supporting `createPattern` with video elements using the GPU process for both media and canvas
        rendering, we still fail this test due to a security error that is thrown when consulting
        `CanvasRenderingContext::wouldTaintOrigin`. This, in turn, is due to the fact that we never attempt to update
        cached `wouldTaintDocumentSecurityOrigin` state on `MediaPlayerPrivateRemote`, so it remains `true`.

        This change will be covered by fast/canvas/canvas-createPattern-video-loading.html, which should now fail with a
        text diff instead of timing out due to lack of support for creating a `CanvasPattern` out of a video element.

        [GPU Process] Canvas layout tests occasionally crash the web process under PutImageData::apply
        https://bugs.webkit.org/show_bug.cgi?id=217140

        Reviewed by Tim Horton.

        When destroying a `RemoteImageBuffer`, logic exists in the superclass (`DisplayList::ImageBuffer`) that attempts
        to flush any remaining display list items. However, this currently doesn't work as intended, since we've already
        finished destroying the subclass, so the superclass' call to `flushDrawingContext()` calls `DisplayList::
        ImageBuffer::flushDrawingContext()` rather than `RemoteImageBuffer::flushDrawingContext()`. Rather than flushing
        display list items to the GPU process, this has the effect of attempting to replay these display list items to
        the drawing context (which is backed by a `DisplayList` anyways), so this ends up having no tangible effect.

        However, if one of these display list items happens to be `PutImageData`, we'll end up hitting an assertion due
        to being unable to apply it without a `Delegate`. To fix this, hoist the call to `flushDrawingContext()` out to
        `~RemoteImageBuffer()`, rather than `~DisplayList::ImageBuffer()`.

        [GPU Process] RemoteImageBufferProxy should ensure the state stack of the context is cleared before destruction
        https://bugs.webkit.org/show_bug.cgi?id=208876

        Reviewed by Tim Horton.

        When running canvas layout tests in debug WebKit, the assertion in `~GraphicsContext()` which verifies that
        `m_stack.isEmpty()` fires. This occurs because the matching call to restore may still be buffered in the web
        process when the remote image buffer proxy in the GPU process is destroyed; however, this may also occur if the
        web process terminates without having sent the matching calls to restore the graphics context.

        We can fix both of these scenarios by manually unwinding the context's state stack when destroying the
        `RemoteImageBufferProxy`. Original patch by Said Abou-Hallawa.

        Move NetworkProcessProxy ownership from WebProcessPool to WebsiteDataStore
        https://bugs.webkit.org/show_bug.cgi?id=216041

        Reviewed by Brady Eidson.

        This patch moves the things on WebProcessPool associated with NetworkProcessProxy ownership and moves them
        to WebsiteDataStore.  It's pretty mechanical, but it reaches its fingers into a lot of things.  Some comments
        on interesting parts are below.

        Why am I doing this?  I'm glad you asked.

        WKWebView had a fundamental cookie problem before this change.  It had a WKWebsiteDataStore that could point to a cookie store on disk
        that could be used in multiple network processes at the same time.  This led to problems with cookies being received over the network
        in those different processes being unable to be shared until they were written to disk, something that does not happen immediately, especially
        on iOS.  This problem is even worse with session cookies, which should be kept in memory and never be written to disk.  Those processes
        did not use shared memory to share the cookies.  They just didn't share them, which led to cookie incorrectness.  This was unfortunately
        the default configuration if you call [[WKWebView alloc] init] more than once, which many developers do.  There was also occasional cookie
        corruption and loss from multiple processes writing cookies to the same file.  All these problems can be worked around by doing what Safari does:
        manually setting the WKProcessPool of all WKWebViewConfigurations to the same process pool to only use one network process.  This is not intuitive
        or well documented, and even though I have spent the majority of WWDC labs for the last 3 years telling developers to do it, most developers do not.
        The default behavior should not lead to cookie incorrectness, corruption, or loss.  This accomplishes that.

        A bigger problem that can't really be worked around well is what we were doing in our WKHTTPCookieStore API.  Many developers call setCookie:completionHandler:
        to "log in" the user by setting a cookie, then in the completion handler, they open a WKWebView to their page and expect the cookie to be sent.  Before this
        change, we would not know which process pool to set the cookie in so we would guess.  If there were no process pools, we would start writing to disk and hope
        it writes fast enough.  We can't wait for it to complete because it causes hangs like rdar://problem/66961066.  This solution allows to start the network
        process of that WebsiteDataStore and set the cookie in that process.  We now know that is the only process this WebsiteDataStore will ever use.  Now, users
        will be able to actually be logged in all the time in such apps.

        This patch removes the remote hosting layer in the GPU process for video fullscreen and

        EnterFullscreen, ExitFullscreen and SetVideoFullscreenFrameFenced IPC messages after removing
        the layer because the RemoteMediaPlayerPrivateRemote in the web process can deal with

        It's possible that `MediaPlayerPrivate::wirelessVideoPlaybackDisabled` is queried before a
        "real" `MediaPlayerPrivate` (i.e. not `NullMediaPlayerPrivate`) is initialized through one
        of the registered `MediaPlayerFactory` "engine"s. It's further possible that the value
        returned by `MediaPlayerPrivate::wirelessVideoPlaybackDisabled` will change as the new
        "real" `MediaPlayerPrivate` may have different logic. In this case, the `MediaPlayer`
        doesn't update its client (and therefore nothing "up" the tree, including the client's
        clients) with the new `MediaPlayerPrivate::wirelessVideoPlaybackDisabled` value, meaning
        that the old value will still be used.

        Add piping such that when the `MediaPlayerFactory` "engine" changes, the `MediaPlayer`
        notifies its client (which is further piped "up" the tree to the client's clients) which
        eventually causes `MediaPlayerPrivate::wirelessVideoPlaybackDisabled` to be re-evaluated.

        Move NetworkProcessProxy ownership from WebProcessPool to WebsiteDataStore
        https://bugs.webkit.org/show_bug.cgi?id=216041

        Reviewed by Brady Eidson.

        This patch moves the things on WebProcessPool associated with NetworkProcessProxy ownership and moves them
        to WebsiteDataStore.  It's pretty mechanical, but it reaches its fingers into a lot of things.  Some comments
        on interesting parts are below.

        Why am I doing this?  I'm glad you asked.

        WKWebView had a fundamental cookie problem before this change.  It had a WKWebsiteDataStore that could point to a cookie store on disk
        that could be used in multiple network processes at the same time.  This led to problems with cookies being received over the network
        in those different processes being unable to be shared until they were written to disk, something that does not happen immediately, especially
        on iOS.  This problem is even worse with session cookies, which should be kept in memory and never be written to disk.  Those processes
        did not use shared memory to share the cookies.  They just didn't share them, which led to cookie incorrectness.  This was unfortunately
        the default configuration if you call [[WKWebView alloc] init] more than once, which many developers do.  There was also occasional cookie
        corruption and loss from multiple processes writing cookies to the same file.  All these problems can be worked around by doing what Safari does:
        manually setting the WKProcessPool of all WKWebViewConfigurations to the same process pool to only use one network process.  This is not intuitive
        or well documented, and even though I have spent the majority of WWDC labs for the last 3 years telling developers to do it, most developers do not.
        The default behavior should not lead to cookie incorrectness, corruption, or loss.  This accomplishes that.

        A bigger problem that can't really be worked around well is what we were doing in our WKHTTPCookieStore API.  Many developers call setCookie:completionHandler:
        to "log in" the user by setting a cookie, then in the completion handler, they open a WKWebView to their page and expect the cookie to be sent.  Before this
        change, we would not know which process pool to set the cookie in so we would guess.  If there were no process pools, we would start writing to disk and hope
        it writes fast enough.  We can't wait for it to complete because it causes hangs like rdar://problem/66961066.  This solution allows to start the network
        process of that WebsiteDataStore and set the cookie in that process.  We now know that is the only process this WebsiteDataStore will ever use.  Now, users
        will be able to actually be logged in all the time in such apps.

        [GTK][WPE] Move TLS errors API from WebKitContext to WebKitWebsiteDataManager
        https://bugs.webkit.org/show_bug.cgi?id=216822

        Reviewed by Alex Christensen.

        Make TLS errors policy per session instead of global to the network process. The web context API now simply
        forwards the request to the website data manager. The website data manager created for an ephemeral web view
        will inherit the network settings from the web context website data manager. This ensures backwards
        compatibility, but it's also convenient, since it's the desired behavior in most of the cases. Apps can still
        change the network settings of the web view by getting the website data manager.

        Reviewed by Said Abou-Hallawa.

        These two tests disable accelerated drawing for canvas elements; when using the GPU process, this causes us to
        use `ImageBufferShareableBitmapBackend` as the back-end for the image buffer backing the canvas element.

        On both macOS and iOS, the image buffer is backed by BGRA image data. However, we override
        `backendColorFormat()` and return `ColorFormat::BGRA` only for `PLATFORM(IOS_FAMILY)`, causing `putImageData`
        and `getImageData` to result in flipped red and blue channels on macOS, which subsequently causes these two
        layout tests to fail.

        Fix these tests by removing the `PLATFORM(IOS_FAMILY)` guard.

        WKWebView Swift overlay has mis-annotated nullability for evaluateJavaScript
        <http://webkit.org/b/216198>
        <rdar://problem/68035950>

        Reviewed by Darin Adler.

        Due to a mistranslation of evaluateJavaScript, we are vending an API which does not expect
        to receive nil as a valid result value. This change fixes the crash, but does not yet fix
        the API to have the correct signature. That will come in a later patch.

        To fix the crash, we need to produce a valid Result<Any, Error> to pass back to clients.
        Fortunately, instead of inventing something clever, we can just use nil. It's valid to box
        optional values into Any, and clients can technically retrieve them with the right dynamic cast
        as well. Since client code must be using dynamic casting to convert the result Any to a usable
        type, and because in the case where we now return a new value at runtime we would have previously
        crashed, this shouldn't have any binary compatibility impact either.

        To better validate these changes, I also add new unit tests for the conversion of JavaScript
        results into Swift values, including a test for the deprecated API.

        * SwiftOverlay/SwiftOverlay/ObjectiveCBlockConversions.swift: Added. For clarity I'm factoring
        helper methods into a single namespace, as it also makes a nice place to document their expectations.
        (ObjectiveCBlockConversion.exclusive.exclusive(_:)): This is renamed from the free function,
            makeResultHandler(_:). It still has the same fatalError (now precondition) as before, but
            hopefully a better name to clarify that it expects exactly-one value.
        (ObjectiveCBlockConversions.boxingNilAsAnyForCompatibility(_:)): This is a variant of exclusive(_:)
            that makes the tradeoff of boxing any nil values as Any to avoid crashing. This is still safe,
            since as mentioned our clients will need to cast the value they recieve to do anything with it,
            and since the deprecated API expects `Any`, no one could have been successfully comparing it
            to `nil` today anyways.

        Allow about:blank subframe loads for non app-bound top frames

        Reviewed by Darin Adler.

        In the original implementation of App Bound Domains, any loads using
        certain protocols like about: were automatically considered app-bound.
        When a subframe loads about:blank for example, this forces web views
        into app-bound mode even if the top frame is not app-bound, which
        should not be the case.

        These special protocols inherit security origins from their top-frame
        loads, so we can refer to those to determine whether subframe loads
        should be considered app-bound. For about: loads in a main frame there
        is no behavior change and WKWebViews will still automatically be considered
        app-bound in this case.

        In WebKitTestRunner, we reset the states and load about:blank page between tests. The resetting may cause some
        activity state changes of web page, like WindowIsActive. Before r266634, these changes will be dispatched
        quickly enough (before runloop waits or when runloop exits) to web process, so web process can do rendering with
        updated activity state. After r266634, dispatch of the changes may be delayed (until CATransaction commits). 
        Page activity state can affect scrollability (in FrameView::computeScrollability()) and scrollability can affect
        tiling size (in TileController::computeTileSize()). Different tilings may cause the tiny pixel difference we see
        in the test results.

        To fix this, create an SPI for sending out activity state updates in next runloop cycle and adopt it in WTR.

          the same time. Also, if a different background thread calls
          exit() in the future with this block running on the main

          the main thread and not knowing where it came from).
        - Add logging (including simulated crash logs) when either of
          these exit() code paths is taken.

        <rdar://problem/67095741>

        Reviewed by Darin Adler.

        When rubberbanding overflow:scroll RenderLayer has an overscrolled scroll offset.
        If RenderLayer::updateScrollInfoAfterLayout() happens when in this state, it can 
        clamp the scroll offset, causing the rubberband to collapse which interferes with
        the user interaction. This happend on Gmail when composing a reply.
        
        Fix by tracking the rubberbanding state in the scrolling tree, and having RenderLayer
        query this state via the ScrollingCoordinator. RenderLayer::updateScrollInfoAfterLayout()
        already tested isRubberBandInProgress(). This is similar to how isUserScrollInProgress()
        and isScrollSnapInProgress() work.
        
        This patch also fixes the tracking of rubberbanding state. Previously setMainFrameIsRubberBanding()
        was just based on when the timer was started and stopped, which did not match the
        implementation of ScrollController::isRubberBandInProgress(). Now ScrollController
        correctly notifies its clients when the rubberbanding state changes by updating that
        state whenever any of the conditions consulted in isRubberBandInProgressInternal() change.

        https://bugs.webkit.org/show_bug.cgi?id=216377

        Reviewed by Geoff Garen.

        In Big Sur, ImageIO uses hardware JPEG decoding automatically for certain JPEGs. This caused
        a small regression in our battery life benchmark since the one-time setup cost for the
        decoder (~20-30 ms per process) was higher than the per-decode win we got from the HW decoder.

        For now, we're reverting to the Catalina behavior of not using hardware JPEG on x86 Macs by
        calling a MediaToolbox SPI. (The tradeoffs for Apple Silicon are different so we use
        ImageIO's default heuristics on that architecture.) We plan to revisit this decision once we
        move to a GPUProcess world.

        Web Inspector: _WKInspectorDelegate should be attached to _WKInspector not WKWebView

        Reviewed by Devin Rousso.

        Move _WKInspectorDelegate to be a property of _WKInspector. If there

        As part of this change, move -didAttachLocalInspector: back to UIDelegatePrivate.
        This delegate method is called just as the inspector is shown, so there would
        be no way to act upon this message if it were part of _WKInspectorDelegate.
        Now, -didAttachLocalInspector: is the designated time to attach _WKInspectorDelegate.

        Web Inspector: modernize generated backend protocol code
        https://bugs.webkit.org/show_bug.cgi?id=216302
        <rdar://problem/68547649>

        Reviewed by Brian Burg.

        Previously, the inspector protocol was expressed in code in a somewhat confusing way:
         - the error string was the first argument
         - required parameters were `T` or `const T&`
         - optional parameters were `const T*`
         - enum parameters were the underlying type requiring the backend dispatcher handler to
           process it instead of it being preprocessed
         - required returns were `T&`
         - optional returns were `T*`
        This doesn't really make for easy/obvious reading of code since the order of arguments is
        not weird (e.g. error string first), and that there are references/pointers to primitive
        types.

        This patch cleans up the generated inspector protocol code to be:
         - required parameters are `T` or `Ref<T>&&`
         - optional parameters are `Optional<T>&&` or `RefPtr<T>&&`
         - enum parameters are preprocessed and passed to the backend dispatcher handler if valid
         - synchronous commands return `Expected<X, ErrorString>` using the same types/rules above
           where `X` is either a single return or a `std::tuple` of multiple returns

        The one exception to the above is `String`, which is already a tri-state of `nullString()`,
        `emptyString()`, and something set, so there's no need to use `Optional<String>`.

        Also use `Protocol` objects/`typedefs` wherever possible to further relate the protocol
        JSON and the actual backend dispatcher handler implementation.

        * UIProcess/Automation/Automation.json:
        `CoordinateSystem` has `Page` and `Viewport` enum values, but `WebAutomationSession` checks
        for `"Page"` and `"LayoutViewport"`. Add a `LayoutViewport` enum value now that enums are
        processed before being passed to backend dispacher handlers to preserve functionality.

        r266634 makes a behavior change that when there is an activity state change, TiledCoreAnimationDrawingArea 
        schedules a rendering update. This breaks timed rendering update from ScriptedAnimationController in the 
        test. If rendering update happens before timer fires, the callback of ScriptedAnimationController will be 
        invoked earlier than expected, thus more callbacks executed in the same time frame.

        To fix this, let's only schedule rendering update when we need to handle activity state change callbacks,
        as before r266634, where we don't schedule activity state timer if there is no callback.

        Reviewed by Tim Horton.

        Various pieces of platform logic in Mac Catalyst depend on the user interface idiom (i.e. Mac or iPad) of the
        app, as well as the application-wide "scale factor". In the context of this bug, NSAttributedString to RTF data
        conversion methods in `UIFoundation` consult the scale factor of `UIiOSMacIdiomManager` to determine whether to
        emit 0 (standard) or 1 (iOS) for the `\cocoatextscaling` attribute. The fact that the web process' scale factor
        may be out of sync with the UI process' scale factor leads to copied RTF data in the web process appearing
        either larger or smaller than expected, due to an incorrect `NSTextScalingType` value.

        To mitigate this (as well as any other issues), we add a mechanism for the UI process to forward the global
        scale factor and user interface idiom to the web process inside of the web process creation parameters, and then
        use new UIKit SPI to override the scale factor and idiom within the web process.

        Reviewed by Simon Fraser.

        Move lazy DisplayLink tear down logic from the WebProcess to the UIProcess, now that the
        DisplayLink has been moved to the UIProcess due to sandboxing.

        After a DisplayLink no longer has any clients, we keep it firing up to 20 times without
        any clients in case a new client gets added shortly after. The idea was to avoid killing
        and respawning too many threads when adding and removing clients in quick succession.
        However, now that the DisplayLink lives in the UIProcess side and sends IPC to the
        WebProcesses every time it fires, it makes a lot more sense to implement this logic in
        the UIProcess side, to avoid sending unnecessary IPC to processes that do not care about
        it.

        Power usage has increased after r260614 due to extra thread hopping. To recover,
        we now process the DisplayWasRefreshed IPC to a background queue if there is

        the user is not scrolling, we keep processing the IPC on the main thread, like

        In WebKit2, we can assume (with the exception of SVG pages) that we must've performed a rendering update prior
        to tracking painting frequencies. As such, we can use the page's rendering update timestamp instead of the real
        current time (`MonotonicTime::now()`).

        Note that in WebKit1, it is possible for any client to force a synchronous paint of the page before the page has
        performed a rendering update, which triggers assertions in `SinglePaintFrequencyTracking::end()`. As such, we
        stick with `MonotonicTime::now()` in WebKit1.

        This has many benefits including the one in the radar, testability, and moving WebKit-specific code from PDFKit to WebKit.

        Now that the HUD is displayed in the UI process instead of in the web content, zooming in keeps the HUD the same size.
        A 3d-transformed iframe with a PDF in it now shows the HUD in the place you can click on it, instead of in the transformed PDF.
        Also, moving the mouse to the HUD within the first 3 seconds prevents it from hiding, which it does when the mouse leaves the HUD.
        The rest of the behavior I think should be the same.  Most users should not notice any difference.

        Move lazy DisplayLink tear down logic from the WebProcess to the UIProcess

        Reviewed by Simon Fraser.

        Move lazy DisplayLink tear down logic from the WebProcess to the UIProcess, now that the
        DisplayLink has been moved to the UIProcess due to sandboxing.

        After a DisplayLink no longer has any clients, we keep it firing up to 20 times without
        any clients in case a new client gets added shortly after. The idea was to avoid killing
        and respawning too many threads when adding and removing clients in quick succession.
        However, now that the DisplayLink lives in the UIProcess side and sends IPC to the
        WebProcesses every time it fires, it makes a lot more sense to implement this logic in
        the UIProcess side, to avoid sending unnecessary IPC to processes that do not care about
        it.

        Webpages flash when switching between windows
        https://bugs.webkit.org/show_bug.cgi?id=216012

        Reviewed by Tim Horton.

        Based on patches from Tim Horton. To avoid flash, we need to make sure view to be selected updates its content 
        before UI process commits its transaction. We did this by making UI process block until receiving a reply 
        DidUpdateActivityState from web process. However, web process did not make sure the reply would be sent after 
        normal rendering update and corresponding transasction commit. Instead, it flushed transactions in progress and 
        replied. To fix this, now we make web process reply in transaction commit handler after rendering update, if
        there is an active transaction.

        In the switching case, view to be unselected will detach from root layer in its web process, which makes its 
        content empty. This change is independent from the UI process commit, so we want this to happen after UI process
        commits (which submits the view hierachy change). Otherwise, empty content(white flash) on the unselected view 
        will be displayed. To fix this, we let UI process send the activity state change message in transaction commit 
        handler, if there is an active transaction.

        REGRESSION (r241734): [iOS] Changing the value of a select element and tapping on another results in two changes
        https://bugs.webkit.org/show_bug.cgi?id=216077

        Reviewed by Darin Adler.

        r241734 added a call to [self _endEditing] in
        [WKContentView _elementDidBlur] to ensure that any open form controls
        are dismissed when using the keyboard to change focus.
        [self _endEditing] calls [_inputPeripheral endEditing], which
        eventually calls [WKFormControl controlEndEditing].

        However, if the focus is changed by tapping on another form control, a
        a gesture recognizer calls [_inputPeripheral endEditing]. Consequently,
        changing the focused element by tapping results in two calls to
        [WKFormControl controlEndEditing]. First from the gesture recognizer,
        and then from [WKContentView _elementDidBlur].

        For certain form controls on iPhone, such as the select element,
        controlEndEditing is responsible for updating the element's value in
        the WebProcess. Note that the same is not true on iPad, as
        controlEndEditing simply dismisses a popover. Now, the first call to
        [WKSelectSinglePicker controlEndEditing] correctly updates the expected
        select element. However, when tapping on another select element, the
        second call to [WKSelectSinglePicker controlEndEditing] also attempts
        to update the value of the focused element. By this time, the focused
        element in the WebProcess is the second select element. Consequently,
        changing the value in one select element and then tapping another
        results in updates to both elements.

        To fix this issue, while preserving the intent of r241734, we should
        prevent callers from being able to end editing in a control twice. Note
        that WKFormPeripheralBase already keeps track of the editing state of a
        control in a boolean variable _editing. If the control has finished
        being edited, _editing is set to false. This patch adds an early return
        to [WKFormPeripheralBase endEditing] if _editing is false, ensuring
        controlEndEditing is never called twice. For parity, also ensure that
        controlBeginEditing can only be called if the control is not already
        being edited.

        The NSDatePicker and NSDateFormatter should use a UTC timezone.
        This is necessary as all double values passed into WKDateTimePicker

        Webpages flash when switching between windows
        https://bugs.webkit.org/show_bug.cgi?id=216012

        Reviewed by Darin Adler.

        Based on patches from Tim Horton. To avoid flash, we need to make sure view to be selected updates its content 
        before UI process commits its transaction. We did this by making UI process block until receiving a reply 
        DidUpdateActivityState from web process. However, web process did not make sure the reply would be sent after 
        normal rendering update and corresponding transasction commit. Instead, it flushed transactions in progress and 
        replied. To fix this, now we make web process reply in transaction commit handler after rendering update.

        In the switching case, view to be unselected will detach from root layer in its web process, which makes its 
        content empty. This change is independent from the UI process commit, so we want this to happen after UI process
        commits (which submits the view hierachy change). Otherwise, empty content(white flash) on the unselected view 
        will be displayed. To fix this, we let UI process send the activity state update message in transaction commit 
        handler.

        Delete unnecessary code. ResourceLoadStatisticsDatabaseStore::clearExpiredUserInteractions()

        expired statistics in
        ResourceLoadStatisticsDatabaseStore::hasHadUnexpiredRecentUserInteraction(),
        which exactly matches behavior in the memory store. If we clear the
        expired statistics before setting the local var oldestUserInteraction,
        then that var will likely always be equal to zero, and the check for
        if (!parameters().isRunningTest && now - oldestUserInteraction < parameters().minimumTimeBetweenDataRecordsRemoval)
        will always be false.

        The only reason we did not notice this extra code is because the
        SQLite query in clearExpiredUserInteractions() was incorrect, causing
        an early return. So the function never worked properly. Fixing the
        query revealed incorrect behavior. 

        No new tests, behavior should not change because this code was not
        being run due to the SQLite error.

        WKMultipleSelectPicker is displayed when a <select multiple> or a

        group rows and disabled rows were selectable in the picker. r175266 added a
        workaround for this issue, preventing group rows from being selectable.
        However, the workaround did not account for disabled rows, which means that
        it is possible to select disabled options in the multi-select picker.

        To fix this behavior, the same fix that was applied to group rows is now
        applied to disabled rows. `pickerView:row:column:checked:` resets the style
        for the associated view if `item.disabled` is true.

        Unreviewed, fix the internal iOS 13.4 build

        The -_selectionClipRect SPI method isn't declared in any private headers on iOS 13.4 and prior. This isn't a
        problem when building with a non-internal SDK since the SPI is declared in the `!USE(APPLE_INTERNAL_SDK)`
        section in `UIKitSPI.h`, but on internal builds of iOS 13.4, this declaration is absent from both the internal
        SDK and `UIKitSPI.h`.

        To fix the build, simply declare it in the IPI section — once we stop supporting iOS 13.4 as a build target,
        this can be moved back into the non-internal section only.

        Programmatic selection of text in a text field causes the highlight overlay to spill out
        https://bugs.webkit.org/show_bug.cgi?id=215647
        <rdar://problem/67404979>

        Reviewed by Darin Adler.

        UIKit consults the SPI method `-_selectionClipRect` on WKContentView to determine the maximum bounds in which it
        is allowed to show text selection UI (i.e. the text caret view, selection highlight views, and selection
        grabbers). Normally, when contentEditable elements and editable text form controls are focused, we plumb the
        bounds of the focused element to the UI process via `focusedElementRect` in editor state's post layout data.
        However, in this case, the selection is inside a readonly text field that is *not* focused; this causes us to
        return `CGRectNull` from `-_selectionClipRect`, which means that UIKit selection UI is not clipped at all and
        instead overflows the bounds of the input element.

        To fix this, rearrange some logic in `WebPage::getPlatformEditorState` in `WebPageIOS.mm` such that we compute
        and send the selection clipping rect if the selection is inside a text form control, even if it is not the
        focused element. In doing this, we also rename some confusingly-named members in `EditorState::PostLayoutData`
        (see below for more detail).

        Split the existing rect member `focusedElementRect` into two: `selectionClipRect` on iOS, and
        `selectionBoundingRect` on macOS. Previously, `focusedElementRect` was set to the focused element's bounding
        rect on iOS (as expected), but on macOS, we set to the bounds of the ranged or caret selection; we proceed to
        use this rect to mean the bounds of the selection anyways in macOS-specific code, so it makes more sense to just
        move this into the macOS-specific section.

        Additionally, after the below change in WebPageIOS, `focusedElementRect` is no longer specific to the focused
        element, so rename it instead to `selectionClipRect` instead. In `WKContentViewInteraction.mm`, this rect is
        effectively only used in two ways: as the selection clip rect for UIKit, and to determine if the selection would
        be completely clipped anyways (in which case we suppress UIKit text interactions), so `selectionClipRect` is a
        name that is suitable for both purposes.

        On some versions of Xcode, using Interface Builder to set up WKWebViews causes the WKWebView to contain two
        WKFlippedViews as subviews; one of these is created and added in the normal initialization path of the web view
        underneath WebViewImpl's constructor, and the other is created and added underneath the superclass (NSView's)
        `-initWithCoder:` implementation.

        This causes issues when hit-testing WKWebView using the `-hitTest:` method, which is expected to return the
        WKWebView itself instead of the inner WKFlippedView. The logic that tries to implement this behavior is in
        `WebViewImpl::hitTest`, which calls into WKWebView's `-hitTest:` method and returns the WKWebView if the hit-
        tested view ended up being equal to the `m_layerHostingView`. Since we end up with two layer hosting views (only
        one of which is the real `m_layerHostingView`), we fail the check and end up returning the other WKFlippedView.
        In the context of this bug, this erroneous hit-test causes AppKit to ask if the WKFlippedView can become the
        first responder upon mousedown (which it cannot), and so the window's first responder remains the same (instead
        of changing to WKWebView).

        To fix this, adjust the constructor of WebViewImpl to avoid making an extra layer hosting view in the case where
        decoding the WKWebView already initialized and placed the layer hosting view, and just use the existing one
        instead.

        IPC::encodeSharedBuffer called SharedBuffer::data() when copying data into SharedMemory,
        requiring the SharedBuffer to combine its data segments. This can be avoided by using
        SharedMemory::copyBuffer() instead.

        REGRESSION (r257667): 1.9x more CPU time in IPC::SharedBufferDataReference decoding during Netflix playback
        https://bugs.webkit.org/show_bug.cgi?id=215232
        <rdar://problem/66637920>

        Reviewed by Geoff Garen.

        Prior to r257667, an IPC message defined a IPC::SharedBufferDataReference argument to allow
        its sender to easily encode SharedBuffer data as a DataReference. SharedBufferDataReference
        cost the same to encode as a DataReference -- both copied data into the Encoder -- but did
        so by iterating over the SharedBuffer's data segments rather than combining them into a
        contiguous allocation. The message argument was received as a decoded IPC::DataReference,
        which stores a pointer into the IPC::Decoder's buffer rather than making a copy.

        In r257667, IPC::SharedBufferDataReference switched its encoder to use IPC::ArgumentCoder's
        SharedBuffer specialization, which works by allocating a SharedMemory buffer, copying
        SharedBuffer data into it, creating a SharedMemory::IPCHandle from it, and encoding the
        handle. It makes only one copy like the old encoder did, but pays the added cost of
        combining SharedBuffer data segments prior to copying by needlessly calling
        SharedBuffer::data() (this should be fixed independently).

        Since this serialization could no longer be decoded by DataReference's decoder,
        SharedBufferDataReference implemented a decoder, also in terms of ArgumentCoder's SharedBuffer
        specialization. It works by mapping a SharedMemory buffer from a decoded
        SharedMemory::IPCHandle and copying that buffer into a new SharedBuffer. This copy is a cost
        that the old decoder did not incur, but in some cases the message receiver would have made
        such a copy anyway and can instead just ref the decoded SharedBuffer. In other cases though,
        the receiver either made no copies or couldn't use the decoded SharedBuffer to avoid making
        its own copy so creating the SharedBuffer was pure added cost.

        There are additional costs from allocating, mapping, and deleting shared memory and Mach
        send rights, but they are offset by savings due to smaller Encoder and Decoder buffers. The
        additional SharedBuffer combining and copying is not offset elsewhere, and on net makes
        sending and receiving IPC::SharedBufferDataReferences use up to 2x more CPU time when
        playing a video on netflix.com in Safari.

        Resolve this slowdown by reverting the argument encoding changes made to
        IPC::SharedBufferDataReference in r257667. For compatibility with code added after r257667,
        the current IPC::SharedBufferDataReference was copied to IPC::SharedBufferCopy and retains
        the behavior of copying into a SharedBuffer when decoded. IPC::SharedBufferDataReference now
        has the pre-r257667 behavior of decoding to an IPC::DataReference. Messages added after
        r257667 whose receivers were designed to handle a SharedBuffer were changed to use
        IPC::SharedBufferCopy, and all other receivers of messages with IPC::SharedBufferDataReference
        arguments were changed to handle an IPC::DataReference.

        The WKWebView._clientNavigationsRunAtForegroundPriority SPI was not working for the
        MessagesViewService because the view is unparented and PageClient::isApplicationVisible()
        would not work return accurate results when [view window] returns nil. It is very
        unfortunate to have to rely on the view or the view's window to determine application
        visibility so this patch fixes this. We now rely on UIKit's visibility endowment to
        determine if the UIProcess is visible, using RunningBoard API. I have verified that the
        visibility endowment properly gets propagated from the host application to the view
        service when the application is a view service and I have verified that this detects
        the MessagesViewService as visible for the use-case at <rdar://problem/67087352>, which
        causes the WKWebView._clientNavigationsRunAtForegroundPriority SPI to work as intended.

        Note that when the application does not have the visibility endowment, we still allow
        it to take a foreground assertion for client navigations if the process is allowed to
        run in the background for an extended period of time, according to RunningBoard. This
        allows the SPI to work for daemons (like maild) which rely on it.

        WKWebViews using fastServerTrustEvaluationEnabled should only allow legacy TLS for main resource loads
        https://bugs.webkit.org/show_bug.cgi?id=215626

        We have introduced public API webView:authenticationChallenge:shouldAllowDeprecatedTLS: in WKNavigationDelegate to allow
        applications to choose whether to allow TLS 1.0 or 1.1 connections.  We don't want to break this API or break existing third party
        apps that load pages that load third party subresources that use TLS 1.0 or 1.1.

        However, we do want Safari, which uses fastServerTrustEvaluationEnabled SPI, to silently fail subresource loads that use TLS 1.0 or 1.1.
        This matches the current behavior of Chrome and Firefox, which was not implemented in those other browsers when we decided to ask about subresources.

        [Cocoa] Avoid changing XPC target queue inside XPC event handler
        https://bugs.webkit.org/show_bug.cgi?id=215460

        Reviewed by Darin Adler.

        In WebProcess::handleXPCEndpointMessages we currently change the XPC target queue for the XPC bootstrap connection while
        under the XPC event handler. This sometimes causes simulated crashes on iOS and should be avoided. According to the
        documentation in https://developer.apple.com/documentation/xpc/1448786-xpc_connection_set_target_queue?language=objc,
        there does not seem to be anything saying this is a programming error, but the simulated crash claims otherwise. This
        patch addresses this issue by changing the initial target queue for the XPC bootstrap connection from the main thread
        queue to a queue on a secondary thread. The WebKit initializer function needs to be called on the main thread, which
        is done by synchronously dispatching the call on the main thread. This patch also stops changing the event handler for
        the bootstrap connection, but instead adds the additional XPC handling to the current event handler.

        No new tests, since this is covered by existing tests. The handling of the Launch Services XPC endpoint message that
        this patch changes, is used to receive the Launch Services database from the Networking process. The Launch Services
        database is used in MIME type mapping APIs, and many tests would fail if this database was not received in the
        WebContent process.

        Convert SharedMemory::Handle objects to SharedMemory::IPCHandle
        objects which automatically verify the size of data being sent.

        We can remove the additional size parameter being sent in many IPC
        messages along with the handle, now that both are stored in the
        IPCHandle struct.

        Remove the need for defining USE_NEW_BUILD_SYSTEM
        https://bugs.webkit.org/show_bug.cgi?id=215439

        Reviewed by Darin Adler.

        When building WebKit for XCBuild, we currently require that the
        external build system (such as the Makefile, build-webkit, etc.)
        defines the USE_NEW_BUILD_SYSTEM=YES build setting. This build setting
        controls parts of our build instructions that are sensitive to when
        XCBuild or the Legacy build system are being used. Notably, we need to
        know when to use our custom “copy and modify” scripts with copying
        certain header files (used with the Legacy build system) vs. using the
        enhanced Copy Headers build phase that’s enabled with
        APPLY_RULES_IN_COPY_HEADERS=YES (introduced with and used by XCBuild).
        The choice of which method to copy headers is used is controlled by
        USE_NEW_BUILD_SYSTEM.

        There is no built-in build setting that we can probe to help us
        determine which approach to take when copying and modifying headers,
        which is why we need to define USE_NEW_BUILD_SYSTEM ourselves. But it
        turns out that we can *detect* which build system is being used by
        taking advantage of a subtle difference between the two systems. As
        noted in:

            https://developer.apple.com/documentation/xcode-release-notes/build-system-release-notes-for-xcode-10

            “When an .xcconfig file contains multiple assignments of the same
             build setting, later assignments using $(inherited) or
             $(<setting_name>) will inherit from earlier assignments in the
             .xcconfig. The legacy build system caused every use of
             $(inherited) or $(<setting_name>) skip any other values defined
             within the .xcconfig.”

        This difference can be exploited as follows:

            WK_WHICH_BUILD_SYSTEM = not_
            WK_WHICH_BUILD_SYSTEM = $(inherited)legacy
            WK_USE_NEW_BUILD_SYSTEM = $(WK_USE_NEW_BUILD_SYSTEM_$(WK_WHICH_BUILD_SYSTEM))
            WK_USE_NEW_BUILD_SYSTEM_legacy = NO
            WK_USE_NEW_BUILD_SYSTEM_not_legacy = YES

        We can then use WK_USE_NEW_BUILD_SYSTEM where we used to use the
        externally-defined USE_NEW_BUILD_SYSTEM.

        No new tests -- no new or changed functionality.

        Add the support to return to element fullscreen from picture-in-picture
        https://bugs.webkit.org/show_bug.cgi?id=215305

        Reviewed by Jer Noble.

        This patch replaces WKFullScreenViewControllerVideoFullscreenModelClient
        with WKFullScreenWindowControllerVideoFullscreenModelClient. We need to do
        that because the instance of WKFullScreenViewControllerVideoFullscreenModelClient
        will be destroyed after the container element exits fullscreen while the video
        element enters picture-in-picture.

        The instance of WKFullScreenWindowControllerVideoFullscreenModelClient
        will always exist when the WKFullScreenWindowController instance is alive,
        so that it can receive callbacks from the VideoFullscreenInterfaceAVKit instance
        to implement the "return to element fullscreen from picture-in-picture" feature.

        This patch supports the following transitions:
        element fullscreen -> picture-in-picture (through user gestures)
        element fullscreen -> picture-in-picture (through the PiP button)
        picture-in-picture -> element fullscreen (when the tab is visible)
        picture-in-picture -> element fullscreen (when the tab is invisible)
        picture-in-picture -> element fullscreen (when the browser is in background)
        picture-in-picture -> inline (when the browser is in foreground)

        iOS: Scrolling and touch events sporadically stop working after navigating

        Test: fast/events/touch/ios/touch-event-stall-after-navigating-with-pending-asynchronous-touch-start.html

        WebPageProxy::handlePreventableTouchEvent keeps a counter of the number
        of outstanding "preventable" touch events that it is waiting to hear
        from the Web Content process about. This counter is incremented when the
        event is dispatched to the Web Content process's EventHandler queue,
        and decremented when the reply (whether it was handled or not) comes
        back from the Web Content process. While the counter is non-zero, all
        deferrable gestures remain deferred (and when it returns to zero, the
        WKDeferringGestureRecognizer gate is lifted, and events are allowed to flow).
        This means that it is very important that every event eventually reply
        about its handling status.

        Before this change, when the Web Content process is navigating, and reaches didCommitLoad,
        it cleared all queued touch events, without replying to to the UI process.
        Thus, there is a small window of time in which an incoming touch event will
        end up in the queue, *not* get dispatched/replied, and then get dropped on
        the floor in didCommitLoad. Most events do not meet this fate, because they
        are handled promptly, and commitLoad/didCommitLoad tend to be very quick.
        However, if the Web Content process ends up spending any significant amount
        of time under commitLoad (say, in an unload handler, or in media frameworks),
        any incoming touch events during that time will get lost, and the UI process'
        count of outstanding events will end up getting stuck non-zero.

        Fix this by always pretending that the page ate any events that were outstanding
        when didCommitLoad occurs, instead of just dropping them on the floor.

        We do not suspend IDB work in the network process when there is an ongoing transaction because the network 
        process is going to ask the UI process to hold a background process assertion for it. However, it is possible 
        that the request from the network process does not reach the UI process in time: RunningBoard may already decide
        to suspend the network process after app is backgrounded and UI process drops the foreground assertion for the 
        network process. 

        In this case, IDB in the network process would continue its transaction and the network process will be killed 
        when it becomes suspened for holding database file locks. A network process crash can lead to a worse result 
        than suspending IDB work, which aborts ongoing transactions, because it will destroy all database connections 
        and transaction. Therefore, let's just suspend IDB work when the network process receives prepareToSuspend

        This test writes to the system pasteboard using `document.execCommand("Copy")`, and then immediately reads from
        the system pasteboard by triggering `document.execCommand("Paste")`. On rare occasions, this fails on iOS, where
        IPC messages for writing content to the pasteboard (e.g. `WebPasteboardProxy::WriteWebContentToPasteboard`) are
        asynchronous, but the IPC message to get the pasteboard change count before pasting (`GetPasteboardChangeCount`)
        is synchronous. This means that `Connection` may end up dispatching the sync `GetPasteboardChangeCount` IPC
        message before dispatching `WriteWebContentToPasteboard`, which causes the pasteboard read to fail, because the
        contents on the pasteboard have changed after starting to read from the pasteboard.

        Note that this is not a problem on macOS since all pasteboard writing IPC is synchronous. Instead of turning all
        of the async iOS pasteboard writing messages synchronous as well, we can fix this by adding a mechanism in
        `WebProcess` to keep track of outgoing async pasteboard write messages; then, before attempting to grab the
        change count when we start reading, wait for any of these pending async writes to finish before we continue.

        In a future patch, we could actually adopt this same mechanism in `SetPasteboardTypes` and neighboring IPC
        messages to turn these all asynchronous.

        Experimental: Cap the expiry of persistent cookies set in 3rd-party CNAME cloaked HTTP responses

        This experimental feature is off by default.

        CNAME cloaking means a host resolves to a a different domain, potentially a
        third-party domain, as part of DNS resolution.

        This patch makes WebKit::NetworkDataTaskCocoa capture any CNAME cloaking for
        the first party host and stores it in a table in the WebKit::NetworkSession.
        It then checks first party subresource loads to see if they resolve to a
        different domain and if so, compare that domain to both the first party
        domain and its CNAME cloaking domain, if there is one. If there's a
        mismatch, it's deemed a case of third-party CNAME cloaking and any cookies
        set in the response of the cloaked subresource load will have their expiry
        capped to 7 days.

        The cases for capping expiry look like this (and are backed by test cases):

        First-party host  | First-party subdomain      | Capped expiry
        ------------------|----------------------------|--------------
        No CNAME cloaking | No CNAME cloaking          | No
        No CNAME cloaking | First-party CNAME cloaking | No
        No CNAME cloaking | Third-party CNAME cloaking | Yes
        CNAME cloaking    | No CNAME cloaking          | No
        CNAME cloaking    | Matching CNAME cloaking    | No
        CNAME cloaking    | First-party CNAME cloaking | No

        [iOS] Keyboard shortcuts and arrow key scrolling stop working after navigating via swipe gesture
        https://bugs.webkit.org/show_bug.cgi?id=215137
        <rdar://problem/65082979>

        Reviewed by Tim Horton.

        The process of starting a navigation swipe gesture causes the first responder (in this case, WKContentView) to
        resign. Subsequently, nothing makes the content view first responder again once the navigation gesture ends,
        even if the gesture is cancelled and we don't end up navigating. This results in several symptoms, two of which
        are that keyboard shortcuts stop working, and pressing arrow keys does not scroll the web view after ending the
        swipe gesture.

        To mitigate this, add a mechanism to have the web view remember that our content view was first responder before
        calling `-startInteractiveTransition:`; after ending the interactive transition (i.e. swipe gesture), we then
        restore the web view's content view as first responder if it is not already first responder (and it is also
        parented, which is not the case when swiping back to close a newly opened tab in Safari).

        Reviewed by Tim Horton.

        `-accessoryDone` is now used to dismiss the strong password AutoFill keyboard after choosing a password on iOS,
        due to how it hides the keyboard without causing the content view to resign first responder; being stuck in a
        state where the content view is not first responder causes several issues when choosing strong passwords on iOS,
        such as keyboard shortcuts no longer working.

        On iPad, to ensure that `-accessoryDone` actually dismisses the keyboard, we need to additionally teach
        `-endEditingAndUpdateFocusAppearanceWithReason:` (when given `EndEditingReasonAccessoryDone`) to allow the
        focused element to blur when dismissing the strong password input view.

        When the MobileGestalt cache is invalid, we issue a temporary extension to the MobileGestalt daemon for the WebContent process,
        which will populate the in-memory cache by doing a set of MobileGestalt queries before revoking the extension. This patch
        finalizes the list of MobileGestalt queries needed to populate the in-memory cache in the WebContent process on iOS before
        revoking the temporary extension to com.apple.mobilegestalt.xpc. This list was compiled by querying every possible MobileGestalt
        key after the temporary extension was revoked, and make a note of all queries that were contacting the MobileGestalt daemon to
        get the answer. The added queries in this patch should make the list complete, and ensures that all cachable values are in the
        in-memory cache before revoking the extension, since every possible MobileGestalt query was tested. This again means that users
        that have an invalid MobileGestalt cache, will have access to the exact same MobileGestalt values, as those users who have a
        valid MobileGestalt cache.

        In order to make for a better text selection experience, we pulled the selection position 
        down to be on the last line selectable, rather than snap the selection to a single position.
        This made for a better selection experience on small text, but we failed to take
        vertical text into account, and a user is locked into only selecting vertical text that ends below the
        other anchor point of the selection. We should have the same behavior for vertical text, but correctly 
        calculated for X instead of Y.
        This does not fix all cases, but it fixes the most glaring cases.

        Launch time regression due to EndowmentStateTracker initialization in WebPageProxy constructor
        https://bugs.webkit.org/show_bug.cgi?id=215029
        <rdar://problem/66362333>

        Reviewed by Geoffrey Garen.

        EndowmentStateTracker was expensive and in a critical code path during MobileSafari app launch. Since
        this code is new, this was a net app launch time regression. To address the regression, the following
        changes were made:
        1. We only need the EndowmentStateTracker to monitor if the app is user-facing or not, so that we can
           suspend / resume media playback as needed. As a result, it is unnecessary to start monitoring
           user-facing state changes as soon as the WebPageProxy is constructed. Instead, we now wait until
           media plays on the page for the first time.
        2. It turns out that over 70% of CPU time in the EndowmentStateTracker constructor was spent getting
           the current endownment for the process. As a result, I updated the code to lazy populate those
           until they are requested for the first time.
        3. The remaining 30% of CPU time in the EndowmentStateTracker constructor was spent constructing the
           RBSProcessMonitor. I moved the initialization of the RBSProcessMonitor from the constructor to
           EndowmentStateTracker::addClient() so that we only construct a monitor when we actually have our
           first client.
        4. All this code was actually only useful for Catalyst app and was therefore doing work on iOS for no
           reason. I properly #ifdef'd out this code so that it now only applies to Catalyst apps.

        Drop ProcessAssertion::Client and replace with a simple invalidation handler
        https://bugs.webkit.org/show_bug.cgi?id=214976

        Reviewed by Brady Eidson.

        ProcessAssertion had a Client class with 2 functions:
        (1) one to indicate that the assertion was invalidated
        (2) one to indicate that the UI assertion is about to expire

        While ProcessAssertion is used in several places, only the ProcessThrottler
        ever sets itself as a client. The reason is that other call sites use
        assertion types that do not expire. Also, (2) only makes sense for
        ProcessAndUIAssertion, not for ProcessAssertion. Only the ProcessThrottler
        is using a ProcessAndUIAssertion.

        I think a better design is to have a simple invalidation handler on
        the ProcessAssertion, that the call site can set if they are interested
        in invalidation.

        Similarly, I added a UIAssertion expiration handler on ProcessAndUIAssertion
        so that the ProcessThrottler can know if the UIAssertion is about to expire.

        This new design also matches more closely the system process assertion API
        that ProcessAssertion / ProcessAndUIAssertion are wrapping.

        This patch also fixes a bug found by Youenn Fablet where the ProcessThrottler
        would only set its invalidation handler in didConnectToProcess(), instead of
        doing it every time a new ProcessAssertion is created in setAssertionType().
        The assertion type can change (e.g. from foreground to background) after the
        process has launched.

        [iOS] Issue a temporary extension to the MobileGestalt daemon when the MobileGestalt cache is invalid
        https://bugs.webkit.org/show_bug.cgi?id=214965

        Reviewed by Geoffrey Garen.

        When the MobileGestalt cache is invalid, some MG queries will fail in the WebContent process, since it has no access to the daemon.
        This can be fixed by issuing a temporary extension to the daemon, and having the WebContent process query all relevant MG values
        while holding the extension. This will bring the values into the in-memory cache, which will be valid after the extension to the
        daemon has been revoked. We will still attempt to rebuild the MG cache if invalid, but since we now have a workaround for when the
        cache is invalid, we can do this on a secondary thread to avoid blocking the main thread. We also only attempt to rebuild once now,
        instead of every time a WebContent process is started. Additionally, add IOKit property read access to "platform-name", since that
        is needed by a MG query.

        No new tests, since testing this depends on having an invalid cache, which is rare, and non-trivial to enforce in the test
        environment.

        <rdar://problem/66261490>

        Reviewed by Devin Rousso.

        On the desktop version of the account creation page on ea.com, tapping a custom selection menu element
        programmatically focuses a real `select` element that is positioned far outside the viewport. As a result, on
        iPad, we still attempt to show a popover for this focused select at the element location. This popover is not
        visible to the user, but on iOS 13, it still steals modal focus from the web view, which means that an
        additional tap anywhere in the window is required to dismiss the (invisible) popover before the user can choose
        one of the options in the custom in-page menu that is shown.

        Furthermore, upon choosing one of these options, the page programmatically focuses the offscreen select again.
        This causes us to re-present the offscreen popover, which requires yet another tap to dismiss on iOS 13.
        However, on iOS 14, this actually results in a crash when attempting to scroll the popover's inner UITableView
        to the selected row.

        To fix both the crash on iOS 14 and the multiple redundant taps required to dismiss the popover on iOS 13, avoid
        showing popovers altogether if the popover's presentation rect is outside the bounds of the content view, since
        we cannot reasonably expect a user to interact with such a popover anyways.

        When we fixed bug 213495 in r263506, we started calling PlatformCAAnimation::setTimingFunction()
        to set the animation-wide timing function of CSS Animations and JS-originated animations alike.
        However, we neglected to update PlatformCAAnimationRemote, used on iOS, to be able to handle
        both animation-wide timing functions as well as keyframe-specific timing functions. This patch
        adds a new "timingFunction" member to PlatformCAAnimationRemote::Properties to allow for this
        and this new member is used in setTimingFunction() and copyTimingFunctionFrom(). Finally, after
        the animation is decoded in the UI process, we call -[CAKeyframeAnimation setTimingFunction:]
        inside addAnimationToLayer() to use this animation-wide timing function.

        This fixes the test added originally in r263506 which would only work flakily, a symptom of this

        Web Share API Level 2: Can only perform one share action per share sheet invocation
        https://bugs.webkit.org/show_bug.cgi?id=214894

        Reviewed by Wenson Hsieh.

        No new tests; our WKShareSheet testing mechanism intentionally bypasses
        actually presenting the share sheet, which is the only way to test this.

        WKShareSheet assumes that UIActivityViewController's completionWithItemsHandler
        is only called once, when the share sheet is dismissed, and uses it to 
        clean up the temporary file written to disk, and send the success state
        to the API.

        However, it is actually called per share action, of which an arbitrary number
        can be performed per UIActivityViewController invocation.

        Defer cleanup until the share sheet is actually dismissed (which we observe
        using UIAdaptivePresentationControllerDelegate's -presentationControllerDidDismiss: callback),
        and respond to the Web Share API with success if *any* attempted share action
        succeeded.

        Fold dispatchDidDismiss and _didCompleteWithSuccess into -dismiss,
        so we only have one "dismiss if needed and also do the requisite cleanup"
        path. -dismiss should only be called when it is no longer possible to do
        additional sharing actions for the current share sheet invocation.

        Full-web browsing applications which also use prohibited Info.plist
        strings should be restricted from using certain powerful APIs like
        JavaScript injection. These apps will have the equivalent privileges
        of an app that opts into App-Bound Domains with an empty
        WKAppBoundDomains key.

        No new tests. Writing a test for this would require being able to
        change TestWebKitAPI's Info.plist between tests, which we do not
        support. I manually tested this by adding a prohibited
        string to the TestWebKitAPI Info.plist then verified that restricted APIs,

        The computation of snap locations in updateSnapOffsetsForScrollableArea() was also broken
        in RTL; we need to snap the right edge of boxes to the right edge of the scroller for the 'start'
        alignment. (Snapping for LTR boxes in an RTL scroller is poorly defined; for now, follow Gecko.)

        Tapping QuickType suggestions for a misspelled word does nothing in Mail compose
        https://bugs.webkit.org/show_bug.cgi?id=214705
        <rdar://problem/58320785>

        Reviewed by Tim Horton.

        In WebKit2-based editing contexts on iOS (such as Mail compose), tapping on a misspelled word will result in
        QuickType suggestions in the input accessory row either showing up blank (i.e. with no suggestions), or will
        show suggestions that are contextual to the text selection prior to selecting the misspelled word. Subsequently,
        attempting to choose of these suggestions results in no text being inserted. This happens for a couple of
        reasons:

        1.  UIKit doesn't attempt to re-request the autocorrection context after tapping on a misspelled word. UIKit
            just uses `-selectWordForReplacement` to extend the selection over the misspelled word, which doesn't
            currently fire any of the selection change callbacks on UIInputDelegate. As a result, UIKit will instead
            believe that the selection is collapsed to the start or end of the misspelled word.

        2.  Upon attempting to compute text suggestions for QuickType, `-[UIKeyboardImpl replacementsFromSelectedText]`
            uses `-textInRange:` to grab the currently selected text, which (in WKContentView) is currently hard-coded
            to always return `nil`.

        We address (1) by bookending `-selectWordForReplacement` with calls to `-beginSelectionChange` and
        `-endSelectionChange`, and address (2) by teaching `-textInRange:` to return the current text selection, only in
        the case where the given `UITextRange` is equal to the current ranged selection.

        (-[WKContentView selectedTextRange]):

        Cache the current selected text range on WKContentView, such that repeated calls to selectedTextRange when the
        selection has not changed does not require a new WKTextRange to be constructed every time.

        Invalidate the cached selected text range whenever the selection has changed.

        Safari Related Leaked Assertions after Playing YouTube Video
        https://bugs.webkit.org/show_bug.cgi?id=214706

        Reviewed by Jer Noble.

        A 10 second grace period before removing the activity token was introduced in r252692.
        However, some websites, e.g., youtube.com, requests the video element to play the
        next video 10 seconds after completing the current one (when the Safari is in the background).
        That can lead to a race condition between the web process and the UI process. They may send
        IPC messages to each other at the same time:
        1) The web process sends a WebPageProxy::IsPlayingMediaDidChange message to the UI process
        to notify that video/audio is playing, so the UI process will take a MediaPlayback assertion.
        2) The UI process sends a WebProcess::PrepareToSuspend message to the web process, which
        will suspend the web process.

        Eventually, the web process will suspend, which means no video/audio playback.
        But the UI process believes that there is a web process playing video/audio, so it will
        take a MediaPlayback assertion.

        This patch fixes the race condition by ignoring the WebPageProxy::IsPlayingMediaDidChange
        message in the UIProcess if the process throttler believes that the process should not be
        running, so that the MediaPlayback assertion will not be created.

        Calling xpc_connection_send_message in the block in WebKit::LaunchServicesDatabaseObserver::LaunchServicesDatabaseObserver will
        sometimes crash because the XPC connection object is invalid. The block is called on a secondary thread, and the m_connections
        member variable needs to be protected by a lock. Also, make sure the XPC connections objects in m_connections are valid by
        retaining them when captured in a block. This is done by redeclaring a local XPC connection variable as an OSObjectPtr instead
        of a raw XPC connection object.

        [macOS] Datalist dropdown scrollbar position does not match visible region
        https://bugs.webkit.org/show_bug.cgi?id=214656

        Reviewed by Wenson Hsieh.

        Currently, the content insets for the dropdown are set on an NSScrollView's contentView,
        rather than the NSScrollView itself. On the latest macOS, this results in accurate state
        within the NSScrollView, leading to an inaccurate scrollbar position. To fix, set the
        content insets directly on the NSScrollView.

        However, on older macOS, setting content insets on the NSScrollView causes the view to start
        out slightly scrolled (by a value equal to the top inset). This issue is solved by preserving
        the existing behavior (setting insets on the contentView) on older macOS.

        Also, set the style of the embedded NSTableView to NSTableViewStyleFullWidth, to ensure the
        view respects the insets we specify.

        No new tests, as the change is purely visual and affects native UI.

        This is the iOS equivalent of the fix in r264203; if the user is scrolling (or we're animating for
        scroll snap), layout should not trigger scroll position changes via computation of the current snap
        location.

        To fix this, we need to send data from the UI process to the web process about which scrolling tree
        nodes the user is scrolling. That's done via RemoteScrollingUIState, which will, in the long term,
        become a more general UI -> WebProcess scrolling state updating mechanism. For now, it just keeps
        track of nodes undergoing scroll snap and user scrolls (only the latter is hooked up for now).

        NetworkConnectionToWebProcess should not handle NetworkRTCProvider messages
        https://bugs.webkit.org/show_bug.cgi?id=214547

        Reviewed by Alex Christensen.

        Normally NetworkRTCProvider is created when starting to monitor the network.
        In case network process is crashing though, there might be requests to open RTC socket on the new network process which has not started to monitor the network.
        In that case, we will go through NetworkConnectionToWebProcess as NetworkRTCProvider is not yet created.
        To properly handle this case, on web process side, we send an IPC message to explictly create the NetworkRTCProvider.
        Once done, we set the IPC connection to the socket factory which will start sending messages to open sockets if needed.
        Until its connection is set, the socket factory will buffer messages to open sockets.
        Covered by test no longer crashing in debug.

        [WebAuthn] Cache the PIN to improve NFC user experience

        <rdar://problem/60073622>

        Reviewed by Brent Fulgham.

        Cache the PIN to improve NFC user experience. Users might not hold the NFC key against the NFC scanner all the time
        while entering the PIN. Therefore, we cache the PIN from the previous connection and immediately return the cached PIN to
        the current connection such that users don't need to enter the PIN again.

        The only downside for this optimization is that a wrong PIN could be used if the user switch to another authenticator for
        the new connection. Given there is no UUID to identify a particular authenticator, there is nothing we can do to resolve the
        issue. The probability of the issue, however, should be rare.

        Covered by new API tests.

        MediaOnly user gesture is more flexible than regular user gesture. For example, it can be propagated through XHR.
        A common use case for WebAuthn is to call the API within XHR events, which could be triggered by user activated events initially.
        By using MediaOnly user gesture, it allows developer to keep using this XHR model.

        In r262280 we stopped the UIWKGestureOneFingerTap gesture from starting if the tap was not inside
        the current selection. That caused the selection to not always be cleared, especially when tapping
        on an element that could create an overlay in which the selection was supposed to be obscured. We 
        short circuited this gesture because it used to cause a sync IPC message to be sent to the web process,
        but that code has subsequently changed, so allowing the gesture to start and clear the selection in all
        cases is no longer a performance concern, so changing the behavior back to allowing the gesture to always
        start, even if the touch is not inside the selection rect.

        ASAN builds of WebKit should not freeze when an EXC_RESOURCE is delivered
        https://bugs.webkit.org/show_bug.cgi?id=214346

        Reviewed by Mark Lam.

        When the WebContent process allocates 1000 MB of memory or starts 32
        threads, it receives an EXC_RESOURCE. This requires iterating all the
        mappings of the process. For the case of a process instrumented with
        AddressSanitizer, the mappings total 20 terabytes, and cause the
        process to "freeze" for several minutes. 

        Setting the sysctl debug.toggle_address_reuse to 1 causes the
        EXC_RESOURCE mechanism to skip iteration of all the mappings. 

        With this patch, setting the environment variable 
        DISABLE_FREEZING_ON_EXC_RESOURCE will set the sysctl mentioned above
        for WebContent and Networking processes.

        r264101 added logic that attempts to share an activated (i.e. long-pressed) element as an image, if the image
        URL scheme for the element is equal to "data" (ignoring case sensitivity). However, in the case where the image
        URL is nil, the call to `[element.imageURL.scheme caseInsensitiveCompare:@"data"]` is 0, which (conveniently) is
        equal to `NSOrderedSame`. This causes us to incorrectly proceed by sharing the element as an image.

        Fix this by going through URL::protocolIsData(), so we don't end up with 0 (`NSOrderedSame`) when

        This is a speculative fix for <rdar://problem/60539389>, wherein hardware key commands seemingly stop working in
        a web page that is (presumably) otherwise responsive. It's possible that the bug exercises a scenario in which
        the completion handler in `-[WKContentView handleKeyWebEvent:withCompletionHandler:]` is never invoked, which
        subsequently leads to the keyboard task queue being backed up with key events.

        This can happen in several ways. For instance, if the web process is swapped or terminates in the middle of
        handling a key event, the key event queue will be cleared, but the UI process will still retain the (uncalled)
        completion handler for that key event. Additionally, `WebPageProxy::handleKeyboardEvent` may not even have
        attempted to propagate the event to the web process, in which case we shouldn't be saving the completion handler
        and waiting for a response.

        Test was flaking because of multiple async calls to submit telemetry,

        makes an SPI call. If the first telemetry call is reported after the test
        sets notifyPagesWhenTelemetryWasCaptured but before the SPI call to capture
        telemetry is submitted, the test will receive the wrong data.
        To fix this, we should simplify by removing the separate function to

        SPI call is made.

        Tell the web process to restore the selection of the focused element when re-focusing it
        on page activation.

        When resigning first responder the text interaction assistant is deactivated and calls
        back into WKContentView's -clearSelection, which clears the focused element and tells
        the web process to clear the selection. Keep in mind that the focused element in the web
        process is not changed. When the WKContentView subsequently becomes first responder the
        web process messages the UI process to tell it to start assistance (aka focus) for focused
        element. However the selection is not restored and thus the editor state the UI process
        has, and is even sent up until there is a selection change, mismatches with the focused
        element information it also has. To match Mac, key events are only passed to the input
        manager if an editable element is focused (see <https://bugs.webkit.org/show_bug.cgi?id=199122>).
        So, key events are not passed to the input manager when in this state. To prevent this,
        restore the selection of the focused element when the element is re-focused because the
        page became active again.

        Selection restoration is driven by the UI process (not the web process) because element re-
        focusing may be denied by the embedding client. In this case, selection should not be restored
        because UI assistance was not started. For the same reason, I do not restore it in -becomeFirstResponderForWebView.

        though -becomeFirstResponderForWebView was called beforehand because -becomeFirstResponderForWebView only
        activates it if there is a non-empty selection. (Note the page having an empty selection could have been
        a result of -clearSelection having been called though the page could have done it programmatically as well).
        I also set a new flag to YES and schedule a full editor state update to ensure this flag is cleared.
        The flag is so that key events that come in between now and the next editor state update are passed to the
        input manager.

        <rdar://problem/64109242>

        Reviewed by Tim Horton.

        It's an error in the embedding client to override the minimum layout size with a negative width or height (in
        this case, Mail on iOS). This happens when double tapping on a contact pill in the "To:" line in Mail compose,
        which causes the top content inset of the web view's scroll view to increase such that Mail's logic for
        overriding layout width ends up passing a negative height.

        After a recent change (<https://trac.webkit.org/r261874>), this now results in the web view immediately
        scrolling to an incorrect content offset when rotating into landscape mode after double tapping a contact. Fix
        this by clamping the overridden layout size to a minimum of (0, 0), to prevent SPI clients from triggering
        subtle bugs like this in the future.

        <rdar://problem/64940487>

        Reviewed by Tim Horton.

        Prior to r259840, when presenting context menus for certain input types (i.e. "time" and "datetime-local") on
        iOS, UIKit would tell the presented view controller's view (a `UIDatePicker` in this case) to become first
        responder. As a result, `WKContentView` would resign first responder, which (by default) blurs the focused
        element and dismisses the context menu. The result is thats time pickers would immediately dismiss upon
        presentation.

        To mitigate this, r259840 adopted the existing active focus retaining mechanism to temporarily decouple
        WKContentView's first responder status from the currently focused form element. However, this also causes
        `-endEditingAndUpdateFocusAppearanceWithReason:` to bail, due to `self.webView._retainingActiveFocusedState`
        returning `YES`. This means that codepaths meant to immediately dismiss UI for the focused element (for example,
        when pressing Escape on a hardware keyboard on iOS) will not be able to dismiss UI.

        To fix this, push the flag that keeps track of whether we're relinquishing first responder to the focused
        element down into `WKContentView`, and have `WKContentView` automatically stop relinquishing first responder to
        the focused element in `-[WKContentView accessoryDone]`.

        Reviewed by Brent Fulgham.

        To be able to deny mach lookup access to the Launch Services database mapping service in the WebContent process, the database needs to be
        sent from the Networking process to the WebContent process, represented by an xpc object. The Networking process is chosen instead of the UI
        process, since WebKit is controlling the sandbox of the Networking process. There is already a direct connection between the Networking
        process and the WebContent process, but this is a CoreIPC connection. Since the database is represented by an xpc object, an xpc connection
        is requiered to transfer the database. This patch creates a direct xpc connection between the Networking process and the WebContent process,
        by creating an xpc endpoint in the Networking process, sending this to the UI process over the bootstrap xpc connection, and then providing
        each WebContent process with this endpoint by sending it over the bootstrap xpc connection between the UI process and the WebContent process.
        This endpoint has to be sent via the xpc connections to the UI process, since the already existing direct connection between the Networking
        process and the WebContent process is a lower level CoreIPC connection, which does not support transferring xpc objects like the xpc endpoint.
        When the WebContent process receives the endpoint, it will create an xpc connection from the endpoint, which will create a direct connection
        with the Networking process. A message is then sent over the connection to request the database xpc object. When the Networking process
        receives this message, it checks the entitlement of the remote end to make sure it is communicating with a WebContent process, and then sends
        the database if the entitlement check succeeds. When the WebContent process receives this message, it performs an entitlement check as well,
        and if successful, the database object is consumed. Consuming this database object, will make sure UTI to MIME type mapping is working
        correctly in the WebContent process.

        For the UI process to be able to pick up xpc messages on the bootstrap connection, a new virtual method, handleXPCEvent, is added to the
        ProcessLauncher Client class. This way, a ProcessLauncher client will be able to pick up xpc messages from the xpc bootstrap connection.
        Previously the event handler for the bootstrap connection in the UI process would handle only xpc error messages. It has now been expanded
        to handle normal messages, which are being forwarded to the ProcessLauncher client. In this case the client is the Network process proxy,
        which will check the message received, and if it turns out to be a message containing an xpc endpoint, the message will be forwarded to
        all Web processes. The ProcessLauncher client can be expanded to handle any xpc message, but right not the Network process proxy only
        handles the xpc endpoint message. The handleXPCEvent virtual method return a RefPtr to an XPCEventHandler, which is captured in the event
        handler of the bootstrap xpc connection.

        No new tests, since there already exist tests for this. UTI to MIME type mapping is being used in WebKit and underlying framework, and many
        tests would fail if this mapping was not working.

        [iOS] Occasional crash under -[UIView _setViewDelegate:] when presenting date and time pickers
        https://bugs.webkit.org/show_bug.cgi?id=214120
        <rdar://problem/65246918>

        Reviewed by Darin Adler.

        This crash happens when attempting to present a date picker (`<input type=date>`) immediately after dismissing
        it. We encounter an Objective-C exception thrown by UIKit, due to the `WKDateTimeContextMenuViewController`'s
        view (the `UIDatePicker`) being presented while it is still owned by the preview view controller. We often avoid
        this crash because the `WKDateTimeContextMenuViewController` is usually only owned by `WKDateTimePicker`, so
        when we set `_viewController` to a new instance of `WKDateTimeContextMenuViewController`, the old view
        controller is destroyed, and thus no longer owns the `UIDatePicker` view.

        However, it's possible for anything (e.g. animation blocks in UIKit) to cause the old view controller to live
        past the creation of the new view controller. If this happens, when we go and call `-setView:` on the new view
        controller with the date picker view, the date picker view may still be the view of the old controller, and we
        end up crashing.

        To fix this, explicitly unload the old view controller's view before attempting to create the new view
        controller.

        REGRESSION (r207558): [Mac] Context clicks on links sometimes result in navigations

        <rdar://problem/64294015>

        Reviewed by Tim Horton.

        WebPageProxy::showContextMenu was written with the assumption that WebContextMenuProxy::show
        would present a context menu and spin a nested run loop, blocking until the menu dismisses.
        Once WebContextMenuProxy::show returns, showContextMenu would send the
        WebPage::ContextMenuHidden message, telling the WebContent process that it's OK to resume
        processing mouse events.

        This assumption was invalidated in r207558 (and again in several subsequent changes), which
        added asynchronous APIs to WKPageContextMenuClient. If the context menu client provides
        context menu items asynchronously, WebContextMenuProxy::show would return -- and the
        WebContent process would resume processing mouse events -- before the context menu was even
        presented. Since context menu presentation is triggered by a mouse press event, it's
        possible that the corresponding mouse release event would be delivered after
        getContextMenuFromProposedMenuAsync was dispatched but before the client responded with menu
        items to present. If this happened, since mouse event processing was not disabled, the
        WebContent process would dispatch a DOM click event to the page, possibly triggering a
        navigation.

        Fix this by teaching WebPageProxy to defer sending WebPage::ContextMenuHidden until the
        context menu has been dismissed, even in cases where the context menu client provides menu
        items asynchronously. Also, take the opportunity to modernize WebContextMenuProxy and its
        subclasses by, e.g., moving duplicated subclass code into the base class, using the client
        pattern, and using WeakPtrs instead of raw pointers/references.

        autocapitalize="words" capitalizes every word's second character
        https://bugs.webkit.org/show_bug.cgi?id=148504
        <rdar://problem/57814304>

        Reviewed by Tim Horton.

        This bug resurfaced in iOS 13 due to timing changes that caused a task added to UIKeyboardTaskQueue to no longer
        get dequeued after the next editor state update is received in the UI process; as a result, UIKit asks us for
        the context before the caret selection (i.e. `characterBeforeSelection`) before we have a chance to update it,
        which means that UIKeyboardImpl's autoshift state will always be off by one character whie typing.

        Note that solely deferring this update until after the next editor state update is received is insufficient to
        fix this bug, since the keyboard's shift state will still be incorrect when typing characters very quickly (or
        if the web process is unresponsive).

        Instead, completely address this bug by adding a mechanism for WKContentView to cache the last character in the
        string that is currently being inserted using `-insertText:`, and return it in `-_characterBeforeCaretSelection`
        until the next editor state update comes in with the real character before the selection. This way, we're able
        to respond to UIKit's requests immediately with a (reasonable) guess of what the character before the selection
        should be, and then follow it up with the actual up-to-date value from the web process during the next editor
        state update (invalidating the stale shift state if necessary). This cached last character should only be
        incorrect in the case where the page uses script to influence what was typed, or the typed character was never
        inserted at all (e.g. typing a newline character in a single line input element).

        Use `_lastInsertedCharacterToOverrideCharacterBeforeSelection`, if it is set.

        (-[WKContentView _characterInRelationToCaretSelection:]):
        (-[WKContentView insertText:]):

        Update `_lastInsertedCharacterToOverrideCharacterBeforeSelection` and ensure an editor state update immediately
        after text is inserted, if we're currently editing an element with `autocapitalize="words"`. The editor state
        update could be unnecessarily expensive, so we don't want to do this unconditionally. Also,
        `autocapitalize="words"` is special in the sense that it is the only autocapitalization type where the platform
        (UIKit) will ask for the last character immediately and use it to unshift the keyboard. Even in the case of
        `autocapitalize="sentences"`, UIKit makes the decision to unshift using information from `kbd` instead.

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

        Clear out `_lastInsertedCharacterToOverrideCharacterBeforeSelection` when the next editor state update is
        received, and invalidate the current keyboard shift state by calling `-clearShiftState`. This SPI method
        automatically schedules a shift state update, as well.

        Note the extra `_usingGestureForSelection` check here, which prevents the keyboard from autoshifting and
        unshifting while changing the selection via loupe gesture.

        [iOS] Sharing an <img> element with a base64-encoded URL shares the URL as raw text instead of an image

        In the case where the <img> element that was the target when the share sheet was brought has its data encoded
        as a base64 URL, we need to share the UIImage that was created as its snapshot as a file rather than the URL
        to avoid a base64 string to be shared instead of the image data.

        To support testing of this, we add a new optional WKShareSheet delegate to indicate that the share sheet will
        show and the provided activity items, which we forward to a new optional WKUIDelegatePrivate delegate method.
        API tests can thus be written to check the data provided to the share sheet.

        No new tests (CrashTracer with no reproduction)
        
        Due to the racy-ness of how PDFKit calls us on the background thread vs. what might be
        happening with the main thread, sometimes the main thread is asked to handle a data
        request either:
        - Before m_data is allocated
          or
        - After it is deallocated

        In either case it's okay to just not handle it.

        Despite understanding how to reproduce in theory, writing a test case has been elusive.

        [iPadOS] Unable to change focus between Google Docs windows by tapping
        https://bugs.webkit.org/show_bug.cgi?id=213985
        <rdar://problem/57083267>

        Reviewed by Darin Adler.

        When putting two Google Docs windows side-by-side on iPad, it's currently not possible to change the window to
        which keyboard input is routed. In native views (e.g. two side-by-side Notes windows), this is normally handled
        by `UITextMultiTapRecognizer`, which is part of the `UITextSelectionInteraction`; tapping to place the text
        selection calls into `-[UITextInteractionAssistant setFirstResponderIfNecessaryActivatingSelection:]`, which
        updates the key window if needed. This doesn't apply to Google Docs because they instead use touch events to
        drive their own "text interaction"-like behaviors instead of relying on system gesture recognizers, which we
        suppress due to the fact that the selection is within a hidden contenteditable.

        But even in non-hidden editable areas, the initial tap to focus an editable element still doesn't automatically
        make the window key, since the editable text interaction gestures are still inactive when tapping to focus an
        editable element. This means two taps are currently required to change the key window when focusing two Safari
        windows side-by-side: the first tap to focus the element (via the synthetic click gesture), and the second tap
        to trigger the editable text interaction tap gesture that is used to set the selection.

        To fix both of these issues, make some minor adjustments to call `-makeKeyWindow` from WebKit when focusing
        editable elements. See below for more details.

        (-[WKContentView _webTouchEventsRecognized:]):

        For the case in Google Docs where a hidden editable element is used and tapping in the page does not result in
        the element being refocused, we additionally need to make sure that we make our window key anyways. Limit this
        hack to tap gestures, and only when there is a hidden focused editable element to emulate platform behavior of
        updating the key window based on the text tap gesture.

        (-[WKContentView _elementDidFocus:userIsInteracting:blurPreviousNode:activityStateChanges:userObject:]):

        Make the content view's window key when focusing an editable element.

        (-[WKContentView hasHiddenContentEditable]):

        Consider the selection to be inside a hidden editable area if the `WebKit::FocusedElementIsTooSmall` flag is set
        as well. While this doesn't affect Google Docs, it does affect some other custom editors, such as Quip.

        (-[WKContentView mouseGestureRecognizerChanged:]):

        Additionally make the current window key when clicking in a hidden editable area with a trackpad on iOS.

        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.

        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

        Crash under IPC::isValidMessageName()

        <rdar://problem/64773416>

        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

        Work towards <rdar://problem/64808138>

        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.

        Reviewed by Geoffrey Garen.

        Use std::min and std::max when the result needs to be copied instead of doing the comparison
        by hand to make the code a tiny bit more clear. Also, don't copy a VisiblePosition when doing
        the min/max in-place. Both of these things are unlikely to effect code generation. If they do,
        the latter makes things a tiny bit more efficient.

        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
        size to the UI process before firing the first layout milestone.

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

        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.

        [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.

        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 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.

        * UIProcess/ios/WKScrollView.mm:
        (-[WKScrollView _setContentSizePreservingContentOffsetDuringRubberband:]):

        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

        to write those preferences in-process, but there should be no attempt at writing these new

        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.

        [iOS] WKProcessAssertionBackgroundTaskManager incorrectly ignores expiration notifications for daemons
        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()

        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

        I tracked this down to ArgumentCodersGLib.cpp. The problem is that we construct a GVariant
        using g_variant_new_from_data(), which does not copy or take ownership of the data, so here
        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.

        When converting the input timestamps to WallTime, we must somehow

        loading).

        As WPE timestamps are just intended to be compared among themselves,
        we use the first processed event as the origin, comparing the

         - the `Canvas` commands and events related to shader programs/pipelines should only exist
           when the corresponding context type exists, namely `ENABLE(WEBGL)` and `ENABLE(WEBGPU)`.

        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.

        Test: TestAsyncMessageWithConnection

        * 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.

        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
        parameters.

        Where available, switch to using the asynchronous

        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.

        - Change `unsigned` type to `size_t` for `alignment` parameters
          for consistency on 32-bit platforms.
        - Templatize Encoder::encode(), Decoder::decode() and
          Decoder::operator>>() methods to reduce duplicate code.  This
          deleted code in source files, added template methods to header
          files, and required a few changes to existing templates in
          header files to disambiguate std::is_arithmetic parameter
          types.
        - Use `typename E` for all template methods that handle enum

        - Use `typename T` for all other template method types.

        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().

        [WK2] Neuter WKFrameIsFrameSet() / WKPageGetFrameSetLargestFrame() C API
        https://bugs.webkit.org/show_bug.cgi?id=211808

        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
        seem worth it anymore.

        [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.

        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

        As a brief refresher, deferring gesture recognizers allow us to handle otherwise blocking touch events
        asynchronously by having all preventable native gesture recognizers require the deferring gesture recognizer to
        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.

        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.

        WKWebView.title should be safe browsing warning's title during a safe browsing warning

        Add a new property to PageLoadState, which allows the title to be set underneath it.
        That way, once the safe browsing warning is closed, we can update the title to what it would've been,

        [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.

        This patch adds a busy timeout for the ITP database to allow for
        some concurrency flexibility when running many WebKitTestRunner tests, which
        recreate the ITP database store very often to test both the memory and
        database stores.

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

        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

        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.

        This patch updates the ITP database to better handle added tables to

        Organize the code to reflect reality: editor state only has marked text rects if layout is

        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.

        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.

        (WebKit::WebPasteboardProxy::grantAccessToCurrentTypes):

        Split the pasteboard access check into two helpers: one to determine whether the web process is allowed to
        request pasteboard types, and another to determine whether the web process is allowed to request pasteboard
        data (in addition to types).

        (WebKit::WebPasteboardProxy::grantAccess):

        Refactor these to use `PasteboardAccessInformation`; see below for more details.

        (WebKit::WebPasteboardProxy::canAccessPasteboardTypes const):

        Return true as long as the accessType is nonnull; this is because either `Types` or `TypesAndData` is
        sufficient for access to pasteboard types.

        (WebKit::WebPasteboardProxy::canAccessPasteboardData const):
        (WebKit::WebPasteboardProxy::accessType const):

        Add a private helper method to return the access type (`nullopt` for no access, `PasteboardAccessType::Types`

        for the given named pasteboard.

        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.

        Stop waiting for a BinarySemaphore on the main thread in the NetworkProcess

        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
        <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
          QuickLookThumbnailLoader.mm if they are written to.

        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

          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.

        Allow for that promise to be resolved by an asynchronous reply block up in the API client.

        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.

        [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.

        Bring Fullscreen API + alert() behavior from iOS to macOS

        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

        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.

        We need to call WebPageProxy::setNeedsDOMWindowResizeEvent() to fire the "resize" event
        in the repaint callback after the exiting fullscreen process is completed and the

        [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.

        after the bundle initialiation function runs, which gives the embedding program the opportunity to
        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>

        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.

        * 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.
