        [WebGPU] Send WebGPU messages in the web process
        https://bugs.webkit.org/show_bug.cgi?id=233396

        Reviewed by Dean Jackson.

        This hooks up our Remote***Proxy() WebGPU implementation to the serializable structs.
        There are 2 pieces: adding converter functions from PAL::WebGPU::X to WebKit::WebGPU::X
        structs (which are serializable) and actually calling the send() function itself.
        Because streaming IPC doesn't support async replies yet, all the async calls are currently
        sync in this patch. I'll be adding support for async streaming messages in a subsequent
        patch, which will migrate callers to use sendAsync() instead of sendSync().

        No new tests because there is no behavior change yet. This is the last untested foundational
        patch in the series. All subsequent WebGPU patches should have tests.

        Remove unnecessary flattening of SharedBuffer when sending them over IPC
        https://bugs.webkit.org/show_bug.cgi?id=233363
        rdar://85600684

        Reviewed by Sam Weinig.

        In several places, a SharedMemory was allocated followed by a copy. To perform
        this copy, the SharedBuffer was flattened which could involve a memory allocation
        followed by a copy of all segments into the final vector.
        We instead make use of SharedBuffer::copyBuffer convenience method which will simply
        copy the individual segment into the newly allocated SharedMemory.

        No change in user observable behaviour.

        Fly-by fix: SharedMemory::allocate is fallible; few instances didn't check the
        returned value. So test that it succeeded and prevent a crash (null deref)

        [WebGPU] Implement GPU process's message receivers
        https://bugs.webkit.org/show_bug.cgi?id=233358

        Reviewed by Dean Jackson.

        The message receivers have two helper objects:
        1. ObjectHeap, which owns all the message receivers. There is intended to be only one of them per document.
        2. ObjectRegistry, which doesn't own anything, but maintains a mapping from WebGPUIdentifiers to objects. This
               registry is necessary because when an object needs to be destroyed, we have to look up which object it
               is by ID.

        Beyond that, this patch just hooks up those two message receivers, and then forwards all received messages to
        the virtual interface that implements WebGPU.

        No new tests because there is no behavior change.

        This patch builds on the work in Bug 231339 and threads the new icons
        feature through the WebKit layer.

        Note: This change also moves the implementation of _WKApplicationManifestIcon
        earlier in the file since the implementation is needed for proper serialization
        of the _WKApplicationManifest.

        Tested by TestWebKitAPI (ApplicationManifest.Icons) test.

        [WebGPU] Add converters from serializable descriptors to interface descriptors
        https://bugs.webkit.org/show_bug.cgi?id=233310

        Reviewed by Dean Jackson.

        The WebGPU abstract interface (in PAL/graphics/WebGPU) has a set of structs for descriptors. These descriptors hold references to
        objects, so these interfaces can't be serialized directly. Instead, we have a parallel set of structs (in WebKit/Shared/WebGPU)
        which replace the object references with WebGPUIdentifiers. The web process side will convert the abstract interface structs
        to the serializable ones, and the GPU process side will convert back. This patch implements the converters back, from the serializable
        structs to the abstract interface structs.

        No new tests because there is no behavior change.

        The ARQL APIs we'd adopted so far were specific to either macOS or iOS. The new camera
        methods are different since they exist on both platforms.

        In order to expose a single message for both platforms, we introduce a new ModelIdentifier
        struct which wraps the UUID string for macOS and the layer identifier for iOS. Then on
        ModelElementController, we have the previewForModelIdentifier() method to get the matching
        ASVInlinePreview for the provided ModelIdentifier.

        This allows getCameraForModelElement() and setCameraForModelElement to be specified for both
        iOS and macOS with a single implementation.

        We also modify takeModelElementFullscreen() to take advantage of ModelIdentifier which showed
        that we had some lingering code in ChromeClient related to this method that was no longer
        necessary following r285922.

        Drop ServiceWorkerClientIdentifier / DocumentIdentifier and use ScriptExecutionContextIdentifier instead

        Reviewed by Darin Adler.

        Drop ServiceWorkerClientIdentifier / DocumentIdentifier and use ScriptExecutionContextIdentifier instead.

        We need to generic identifier type to identify script execution contexts globally. This patch augments
        ScriptExecutionContextIdentifier with a process identifier to make it app-global, and then gets rid of
        ServiceWorkerClientIdentifier & DocumentIdentifier (which become obsolete).

        This is useful for Web Lock API support as we need a clientId that is consistent between the Web Lock
        API and the service worker API (tested by imported/w3c/web-platform-tests/web-locks//clientids.tentative.https.html).
        The clientId in service workers was using the ServiceWorkerClientIdentifier type, which made little
        sense to use for the Web Lock API given its name.

        Add IPC messaging to start/stop metadata gathering from WebProcess to GPUProcess.
        Add IPC messaging to push metadata to WebProcess, including sending the corresponding CVPixelBuffer for the current metadata.
        MediaPlayerPrivateRemote will then serve that buffer when being requested the current image.
        This ensures that painting on a canvas does not mark the current buffer as acquired, which would then skip the video frame metadata gathering.
        This also ensures the same buffer is used if a video element is painted several times during the same rvfc callback.
        This has the side benefit of removing the synchronous IPC to paint the video element in a canvas.

        [WebGPU] Add IPC message handlers for WebGPU
        https://bugs.webkit.org/show_bug.cgi?id=233247

        Reviewed by Dean Jackson.

        Add classes in GPUProcess/graphics/WebGPU to receive WebGPU's IPC messages.
        Each one of these classes has an associated messages.in file. Each of these objects
        holds a backing PAL::WebGPU object which is the actual implementation. The methods
        that receive the IPC messages are currently unimplemented, but in a subsequent patch
        they'll just forward on the calls to their backing PAL::WebGPU object.

        This also adds serialization routines for all the structs in Shared/WebGPU.

        No new tests because there is no behavior change (yet). We're very close, though!!!!

        PCM: Add capability for click destination to fire triggering event without cross-site requests to the click source
        https://bugs.webkit.org/show_bug.cgi?id=233173
        <rdar://79426605>

        Reviewed by Alex Christensen.

        This patch enables click destination sites a non-JavaScript way to fire triggering
        events without a requirement to make cross-site requests to source sites. This is
        referred to as a "same-site pixel API" and has been discussed in W3C Privacy CG:
        https://github.com/privacycg/private-click-measurement/issues/71

        The reason why some merchants want such an "API" is reluctance to deploy new
        JavaScript on their sites. In some industries it's even a compliance issue. Legacy
        "pixels" are however accepted and so a same-site "pixel" can work for them.

        Reviewed by Dean Jackson.

        Bug 232848 factored platform-specific code out of HTMLModelElement with the use of a new ModelPlayer
        abstraction with a concrete ARKitInlinePreviewModelPlayer implementation. This first patch moved the
        macOS code, and this patch moves the remaining iOS code.

        To do so we make ARKitInlinePreviewModelPlayer a parent class of two platform-specific subclasses:
        ARKitInlinePreviewModelPlayerMac and ARKitInlinePreviewModelPlayerIOS. We add a new enterFullscreen()
        method to ModelPlayer, with an implementation in the iOS subclass. To support this new method, we
        add a new platformLayerID() on ModelPlayerClient.

        [WebGPU] Start preparing for serializing commands to the GPU process
        https://bugs.webkit.org/show_bug.cgi?id=233179

        Reviewed by Alex Christensen.

        The interaction between WebGPU and the GPU process will work as such:

        1. We have a virtual interface in PAL which holds 3 things:
               a) Refcounted objects (command buffer, queue, device, etc.).
               b) Structs holding descriptors for commands. E.g. device.createRenderPipeline(RenderPipelineDescriptor)
               c) Enums
           The virtual interface holds all 3 of these things. For refcounted objects, it holds virtual interfaces with no
           implementations. (There is one implementation of these interfaces which connects them to WebGPU.framework.)
        2. This patch adds a new implementation of these virtual interfaces, called Remote***Proxy, in
           WebKit/WebProcess/GPU/graphics/WebGPU. The implementation of all the methods in this implementation will simply
           send messages to the GPU process. In this patch, these methods are still stubs - they'll be filled in in a
           subsequent patch.
        3. The arguments to the commands consist of the structs and enums from PAL. However, we can't use the structs
           directly, because the structs hold references to the refcounted objects. E.g. a BindGroupDescriptor holds a
           reference to the Buffer which should be part of the bind group. We can't send refcounted objects across IPC,
           so instead of sending the objects, we send a WebGPUIdentifier instead. Every refcounted object gets a unique
           WebGPU identifier. However, because these references to RefCounted objects are buried deep inside nested structs,
           we can't simply use the structs out of the box. Instead, we have to have a parallel set of structs, where the
           references are replaced with WebGPUIdentifiers. These structs will be the ones actually sent across the wire.
        4. The enums don't have this problem, so those are untouched. A subsequent patch will be adding the EnumTraits
           directly in PAL to make them serializable.
        5. Upon receiving a struct from the wire, we're going to have to convert it back into its corresponding PAL type,
           which means we have to find the object associated with the WebGPUIdentifier. The serializers themselves can't do
           this, because they lack the context necessary for performing the lookup. This patch adds two new context objects
           which we'll use ourselves when implementing our own conversions - ConvertToBackingContext and
           ConvertFromBackingContext. Only the first one is implemented in this patch; the second will be implemented in a
           subsequent patch.
        6. The GPU process side won't actually implement the virtual interface - only the web process side will implement it.
           Instead, the GPU process has to manage lifetime of the objects. Just like how 2D canvas in the GPU process has
           a RemoteResourceCache, the WebGPU objects will be owned by a high-level object in the GPU process. The
           ownership will be top-down in the GPU process, where Devices have strong references to Textures, and Textures
           have strong references to TextureViews. On the other hand, in the Web process, ownership will be bottom-up:
           JavaScript will have strong references to TextureViews, TextureViews will have strong references to Textures, and
           Textures will have strong references to Devices. This works out quite nicely - it means that, when GC runs and
           a TextureView gets deleted, the TextureView tells its owner that it's getting destroyed, its owner sends a
           message to the GPU process, and the corresponding owner in the GPU process looks up its relevant child in its
           children list, and delete it. Easy peasy.

        No new tests because there is no behavior change (yet). We're getting close, though!

        In the event where the committed WebProcess would crash while a cross-site provisional load
        is going on in a provisional page / WebProcess, we would do a null dereference of the page's
        drawing area when trying to commit the provisional page later on. We would also hit various
        assertions in debug since the page's state gets completely reset when its WebProcess crashes.

        To address the issue, we now clear the provisional page if the page's WebProcess crashes.

        Reviewed by Darin Adler.

        Decoder::unwrapForTesting() is unnecessarily inefficient. It can take the whole
        m_attachments data members from the decoder instead of calling removeAttachment()
        repeatedly on the Decoder.

        Also rename removeAttachment() to takeAttachment() since it returns the Attachment.
        Update it to return a std::optional<Attachment> instead of using an out-parameter.

        Do more bound validation insde createMessageDecoder() to make sure we stay within
        the bounds of our ReceiveBuffer.

        Also, when the body is out of line, set `out_of_line.deallocate` to false since
        we are taking ownership of the memory and will vm_deallocate() it ourselves.
        Normally the sender (Connection::sendOutgoingMessage) sets that flag to false but

        WebKit is unable to recover if a WebProcess gets terminated while it is launching
        https://bugs.webkit.org/show_bug.cgi?id=233001
        <rdar://85302938>

        While investigating <rdar://83941760>, I found that the WebAuthn Process would get
        jetsammed, which would cause us to call WebProcessPool::terminateAllWebContentProcesses().
        I also noticed that if one of these WebProcesses was still launching at the time
        of the termination, then the WebProcessProxy / WebPageProxy would keep thinking the
        WebProcess is still launching and would never attempt to relaunch it. This would result
        in a blank and unresponsive WKWebView which wouldn't be able to do any loads.

        The issue was due to ProcessLauncher::terminateProcess() calling invalidate(), which
        it would not only terminate the XPC connection, it would also null out m_client. As a
        result, we wouldn't notify the client that the process failed to launch. To address
        the issue, I move the XPC connection termination logic out of invalidate() and into
        its own terminateXPCConnection() function. I then called terminateXPCConnection()
        instead of invalidate() inside ProcessLauncher::terminateProcess().

        [WebAuthn] Stop serializing BufferSource and Vector<uint8_t> duplicates of identifiers
        https://bugs.webkit.org/show_bug.cgi?id=233011
        <rdar://problem/85313807>

        Reviewed by Chris Dumez.

        The original WebAuthn logic converted WebCore::BufferSource objects to Vector<uint8_t>
        during serialization, which created a weird design where some code dealt with BufferSource
        objects, and other with Vectors, and lots of converting to and from these types. It also caused
        WebAuthn data structures to have two places where this information might live, with the
        UIProcess using one representation, and the WebContent process using another.

        This patch revises the code as follows:

        1. The identifiers are always stored as BufferSource, and the same member is used in UIProcess
           and WebContent process when accessing this information.
        2. We now serialize BufferSource directly.

        Tested by existing WebAuthn test cases (API and Layout tests)

        Reviewed by Darin Adler.

        Added callbacks to log memory usage metadata the first time a process hits these milestones:

         - exceeded inactive memory limit while active (on Mac)
         - exceeded warning process limit threshold (on other non-Mac Apple platforms)
         - exceeded critical process limit threshold (on other non-Mac Apple platforms)

        The reason for this is we  receive a large number of out of memory reports with very little
        info in the logs. We want to log more metadata about memory usage (similar to what we do on
        Mac in `WebCore::logMemoryStatisticsAtTimeOfDeath`) to help us debug those reports.

        Add basic support for launching CaptivePortalMode WebProcesses
        https://bugs.webkit.org/show_bug.cgi?id=232737
        <rdar://84473037>

        Reviewed by Brent Fulgham.

        Add new `WKWebpagePreferences.captivePortalModeEnabled` API to allow clients apps to opt in or
        out of captive portal mode for each navigation (WKWebpagePreferences is passed with the navigation
        policy decision). For setting the default state of this setting, the client can set
        `WebWebViewConfiguration.defaultWebpagePreferences.captivePortalModeEnabled` (will impact all views
        using this configuration).

        Note that both this property can only be set by apps with the browser entitlement on iOS (no
        restriction on macOS). On iOS, the default value of WKWebpagePreferences.captivePortalModeEnabled
        depends on the corresponding system setting. For now, this is simulated by a NSUserDefault but it
        will eventually come from somewhere else (TCC?).

        Whenever transitioning in or out of captive portal mode, we process-swap on navigation policy
        decision. Whenever captive portal mode is enabled, we turn off JIT, generational and concurrent GC
        in the WebProcess, as soon as it launches.

        Covered by new API tests.

        When a page is loaded through SafariViewService, the UIProcess is SVS, but the "presenting"
        application is the client of SafariViewController. To further compliate things, multiple apps
        all using a SafariViewController will use a singleton SafariViewService application. When such
        an application goes to the background while playing audio, the audio subsystem will keep the
        UIProcess from suspending, but not the presenting application. The audio subsystem will see
        that the presenting application has become suspended, and will interrupt audio playback.

        Opt into a AVAudioSession behavior where a client can provide an array of audit tokens for
        those processes which are "presenting" the audio playback to the user. This will include the
        UIProcess, but also the process which is hosting the SafariViewController. The audio subsystem
        will keep the processes in that list from becoming suspended during audio playback.

        Since there may be different clients of SafariViewService existing simultaneously, only include
        those presenting application tokens whose WebContent processes require an "active" audio session.

        REGRESSION (Safari 15): AudioContext.currentTime speeds up (and audio won't play) when Bluetooth speaker connected
        https://bugs.webkit.org/show_bug.cgi?id=232728
        <rdar://problem/85075538>

        Reviewed by Jer Noble.

        This was a regression from us moving WebAudio to the GPUProcess in Safari 15. The issue occurred because the
        WebProcess (writer) would get further and further ahead of the GPUProcess (reader) after a hardware sample
        rate change.

        When rendering on https://mdn.github.io/webaudio-examples/audiocontext-states/ with a hardware sample rate of
        96Khz, RemoteAudioDestination::render() would get called with a numberOfFrame=128. Each time
        RemoteAudioDestination::render() was called, it would signal the IPC semaphore, causing the WebProcess to
        produce one WebAudio rendering quantum (128 frames). This would match perfectly and there would be no issues.
        However, if during playback, the hardware sample rate changes (which can happen when connecting to bluetooth
        speakers), CoreAudio would start calling RemoteAudioDestination::render() with a different numberOfFrame.
        For example, when switching the hardware sample rate to 44.1Khz, numberOfFrames would be 278. Every time it
        is called, render() would signal the semaphore 3 times, causing the WebProcess to produce 3 WebAudio rendering
        quantums (3 * 128 = 384 frames). So each time render() is called, the WebProcess would generate `384 - 278 = 105`
        frames too many, causing it to get further and further ahead of the GPUProcess. One symptom would be that
        AudioContext.currentTime would progress too fast. Also, eventually, our RingBuffer between the 2 process would
        fill up and lead to rendering issues.

        To address the issue, I updated RemoteAudioDestination::render() to keep track of how many extra samples it
        requested from the WebProcess previously. This avoids signalling the IPC semaphore too many times and the
        WebProcess can no longer get too far ahead of the GPUProcess. The logic matches what was already done in
        RemoteAudioMediaStreamTrackRendererInternalUnitManager::Unit::render().

        SpeechRecognitionRealtimeMediaSourceManager::Source uses shared ring buffer to pass audio data to

        to SpeechRecognitionRemoteRealtimeMediaSource (so SpeechRecognitionRemoteRealtimeMediaSource can create a

        two, which means m_numberOfFrames may be not the number used. We should get the actual frameCount in the

        Make it possible to toggle several experimental media features when GPU Process is enabled
        https://bugs.webkit.org/show_bug.cgi?id=232818

        Reviewed by Tim Horton.

        Refactor a bit of logic around `GPUProcessProxy::updatePreferences`, such that the experimental features that
        are set underneath this method can be toggled by checking or unchecking the preference in the experimental
        features menu in Safari, and then restarting Safari (or simply killing and relaunching the GPU process).

        As detailed in the existing FIXME, we currently consult the global WebPageGroups' WebPreferences, which do not
        account for changes to the experimental feature defaults since they initialize their own WebPreferences that
        are (1) prefixed with a unique identifier, and (2) have `keyPrefix` and `globalDebugKeyPrefix` that are
        different from normal WebPreferences on WebPageProxy.

        Instead, we can add some plumbing to provide a WebProcessProxy to `updatePreferences()`, and use this to
        determine whether we need to enable any experimental features by iterating over each WebPageProxy's preferences
        and enabling each feature if it's enabled by at least one web page (roughly matching the current behavior).
        While it's still not ideal, these features are all process-global and there is only one GPU process, so in lieu
        of more extensive refactoring around these media feature flags, it makes sense to just turn them on if it's
        enabled in any individual instance of WebPreferences.

        [iOS] IPC decoder for ResourceRequest loses systemPreviewInfo when there is platform data
        https://bugs.webkit.org/show_bug.cgi?id=232769

        Reviewed by Wenson Hsieh.

        The IPC decoder for ResourceRequest decodes systemPreviewInfo and sets it on the ResourceRequest.
        It then uses different code paths to decode the rest of the ResourceRequest based on whether or not
        there is underlying platform data. If there is underlying platform data, we call decodePlatformData()
        which creates a brand-new ResourceRequest, and thus loses the systemPreviewInfo we've just set.

        To address the issue, we now decode extra data members *after* decoding platform data instead of
        *before*.

        This was causing the ProcessSwap.SameOriginSystemPreview API test to fail on iOS with the patch for

        rdar://84979791

        Reviewed by Simon Fraser.

        Resetting a <form> element containing an <input type=color> resets
        the value of the color input. If the WebProcess believes that a
        color picker is visible in the UIProcess, an IPC message
        (WebPageProxy_SetColorPickerColor) is sent to the UIProcess to update
        the selected color.

        If the color picker is closed by user action (on macOS, clicking
        outside the popover), the UIProcess nulls out `m_colorPicker`, and
        notifies the WebProcess that the color picker is no longer visible
        by sending the WebPage_DidEndColorPicker message.

        Consequently, it is possible for WebPageProxy_SetColorPickerColor to be
        dispatched in the UIProcess after `m_colorPicker` is nulled out, while
        the WebProcess is still waiting to process WebPage_DidEndColorPicker.
        This sequence of events results in a MESSAGE_CHECK failure in
        WebPageProxy::setColorPickerColor, leading to WebProcess termination.

        To fix, remove the MESSAGE_CHECK and replace it with a null check, since
        a null `m_colorPicker` is a valid state.

        [GPU Process] Rendering backend may stop processing IPC stream messages after a sync message timeout
        https://bugs.webkit.org/show_bug.cgi?id=232580

        Reviewed by Tim Horton.

        Currently, it's possible for sync IPC messages that are sent through IPC streams to time out and subsequently
        cause the IPC stream server (e.g. RemoteRenderingBackend) to stop processing IPC stream messages altogether. The
        following example illustrates how this might happen:

        1.      Web process sends the sync message at offset `n` (relative to the start of the ring buffer).
                Web process then begins to wait for the sync stream response under `tryAcquireAll()`.

        2.      GPU process receives the sync message, and takes a while (> 1 sec.) attempting to dispatch it.

        3.      Meanwhile in the web process, we hit the IPC timeout and bail from `tryAcquireAll()`. The client offset
                is still at `n`. Shortly afterwards, the web process tries to send a regular stream message, calling
                `tryAcquire()` and waiting for the client semaphore to be signaled.

        4.      The GPU process finally finishes dispatching the sync message from (2), sends a sync reply (unaware that
                the web process has already given up waiting), and finally calls `releaseAll()`, signaling the client
                semaphore. The server offset is then reset back to 0.

        5.      The web process finishes waiting, returns from `tryAcquire()`, proceeds to write the new stream
                message after offset `n`, and wakes up the GPU process with the intention of handling this message.

        6.      The GPU process wakes up and begins reading from offset 0. The first message it encounters is the
                `SyncMessageReply` it just wrote in step (4), and subsequently bails from the processing loop because it
                isn't capable of dispatching this message (which was meant to be consumed in the web process in the
                first place).

        In summary, the sync IPC timeout causes us to enter a state where the web process continues to encode messages
        at the buffer offset prior to timeout (i.e. offset `n`), while the GPU process is reading from the start of the
        buffer (offset `0`). To avoid this, simply replace the timeouts when synchronously grabbing image data from the
        GPU process. This ensures that we're never in a state where we're continuing to send stream messages to a
        rendering backend connection stream after timing out when waiting for a previous sync message to that stream to
        finish.

        Terminate unresponsive network process by crashing it

        Reviewed by Chris Dumez.

        UI process currently kills network process when it does not respond message in some time (network process being 
        unresponsive). We've found one common case where network process becomes unresponsive is that it is blocked by 
        some slow operation on the main thread (like file operation in rdar://84511633). To understand what the 
        operations are and make a fix, we now ask network process to crash itself on IPC thread. In this way, we can get 
        crash report that includes the call stack of the main thread. To avoid generating too many crash reports, we 
        only send the crash message to network process when it becomes unresponsive multiple times in a short time 
        period.

        [WinCairo] New GraphicsLayer for GPU process mode
        https://bugs.webkit.org/show_bug.cgi?id=228308

        Reviewed by Don Olmstead.

        Added a new GraphicsLayer implementation GraphicsLayerWC which
        transfers GraphicsLayer tree to GPU process and runs the
        compositor (TextureMapper) in GPU process.

        In GPU process mode, WebGL is run in GPU process. So, the
        compositor should be run in GPU process. Otherwise, the output
        texture of WebGL has to be transferred from GPU process to the
        compositor process (UI process or web process).

        Because ANGLE isn't thread-safe, the compositor and WebGL should
        be run in the same thread in GPU process.

        Enabling gpu_process_webgl also enables GPU process compositing now.
        > reg add HKEY_CURRENT_USER\Software\WebKit /v gpu_process_webgl /t REG_DWORD /d 1 /f

        gpu_process_canvas_rendering can also be enabled.
        > reg add HKEY_CURRENT_USER\Software\WebKit /v gpu_process_canvas_rendering /t REG_DWORD /d 1 /f

        Enabling gpu_process_dom_rendering is still experimental.
        > reg add HKEY_CURRENT_USER\Software\WebKit /v gpu_process_dom_rendering /t REG_DWORD /d 1 /f

        Layer tree should not be stuck in frozen state after explicitly stopping a page load
        https://bugs.webkit.org/show_bug.cgi?id=232532
        rdar://84522357

        Reviewed by Tim Horton.

        From diagnostic logs gathered in rdar://84522357, it's apparently possible for the layer tree to be stuck in a
        state where it's indefinitely frozen after the user explicitly stops the page load (e.g. by tapping on the "x"
        button in Safari). Specifically, these logs indicate that the `PageTransition` layer tree freeze reason may
        persist even after the user has canceled the load, leading to situations where content may be visible but
        unresponsive.

        From code inspection, this may happen for multiple reasons, one of which is that a media element has incremented
        the load event delay count, which in turn prevents us from transitioning to completed state inside
        `FrameLoader::checkLoadCompleteForThisFrame()`. It's unknown whether this (in particular) is the cause of
        unresponsiveness observed by the reporter of rdar://84522357, but we can at least use this in order to come up
        with a layout test; to mitigate all instances where the `PageTransition` reason may persist after the load has
        been stopped, we make `WebPage::stopLoading()` complete the page transition (thereby lifting the freeze reason)
        if needed.

        [GPU Process] Small ImageBuffers cause the web process to crash
        https://bugs.webkit.org/show_bug.cgi?id=232470
        <rdar://problem/84626560>

        Reviewed by Tim Horton.

        The problem is when the (floating point) size < 1x1, but the size*resolution is >= 1x1.
        In this situation, calculateSafeBackendSize() is correctly determining that this
        isn't a zero-sized ImageBuffer, but when we go to actually pass the size to the GPU
        process, we call this:

        IntSize logicalSize() const override { return IntSize(m_parameters.logicalSize); }

        So, the logical size gets truncated down to 0, and then the GPU process fails to allocate
        the ImageBuffer, and then the web process blocks on the GPU process indefinitely, and then
        eventually times out and then crashes. I'm going to deal with that last step (the crash
        itself) in a secondary patch - if the web process doesn't hear from the GPU process, it
        shouldn't crash.

        This patch simply exposes a floatLogicalSize() function on ImageBuffer, so we can get
        the full-fidelity logical size to pass that to the GPU process.

        We stop delivering messages as soon as |m_valid| becomes false. It is
        thus a good idea to cancel any pending async reply handlers as soon
        as we set m_isValid to false. We were doing it correctly in connectionDidClose()
        but not in invalidate(). The Connection destructor would eventually call
        the async reply handlers. However, I have noticed when investigating a leak
        that this may delay the calling of the reply handler for a long time if
        something keeps the Connection alive (or forever in case of a leak).

        To fix this, sneak the fake scale into setCTM/getCTM (multiplying it in in get,

        Reviewed by Tim Horton.

        Make it easier to correlate release logging from "ViewGestures" and "ViewState" categories in WebKit2 by having
        "ViewGestures" logging include "pageProxyID=...", instead of just the content view pointer. This makes it more
        straightforward to (for instance) detect when the user is trying to interact with a page that has stopped
        receiving layer tree commits in the UI process for an extended period of time.

        Note that in all of the below codepaths, we either already call into `_page`, or they're called as a result of
        gesture recognizer delegate methods that should never be invoked by WebKit clients prior to common
        initialization (where we initialize `_page`), so null checks for `_page` are unnecessary here.

        REGRESSION (iOS 15): Touch events are not fired during quick successive taps
        https://bugs.webkit.org/show_bug.cgi?id=232324
        rdar://83455472

        Reviewed by Wenson Hsieh.

        To support Live Text on iOS 15, two new gesture recognizers were added
        to `WKContentView`. When the gesture recognizers were added,
        `-[WKContentView deferringGestureRecognizer:shouldDeferOtherGestureRecognizer:]`
        was not updated, resulting in a failure dependency between the new gesture
        recognizers and the touchstart deferring gesture recognizer for "immediately
        resettable" gestures.

        The failure dependency causes the entire "immediately resettable" subgraph
        (which contains UIWebTouchEventsGestureRecognizer) to have a delayed reset,
        as the new gestures recognizers are connected to the "delayed resettable"
        subgraph by way of UIKit's exclusion gestures that control context menu
        presentation. The delayed reset prevents successive touches from being
        recognized, and touch events are only recognized after the delay has
        passed. Consequently, quick successive taps result in some touch events
        being dropped.

        To fix, remove the existing failure dependency and instead add an explicit
        failure dependency to the "delayed resettable" subgraph. This ensures the
        immediately resettable subgraph can reset as intended.

        No new tests, as the issue has been difficult to reproduce in WebKitTestRunner,
        even though it reproduces consistently in Safari. Filed webkit.org/b/232326

        bailing in `-_removeContextMenuHintContainerIfPossible`. To fix this, we add a boolean flag to track when the
        context menu presentation animation is running, and avoid unparenting the preview container if the flag is set.

        (-[WKContentView _contentsOfUserInterfaceItem:]):
        (-[WKContentView contextMenuInteraction:willDisplayMenuForConfiguration:animator:]):

        To test this change, add an assertion that fires if the context menu preview hint container has already been
        unparented by the time we've presented the context menu. This assertion already fires during the extant layout
        test fast/events/touch/ios/long-press-on-link.html, which technically exhibits the bug (albeit in a more subtle
        way).

        Reviewed by Chris Dumez.

        I inadvertently introduced a ref-counting cycle between RemoteRenderingBackend and RemoteDisplayListRecorder
        after IPC stream refactoring in r284079, since RemoteDisplayListRecorder directly strongly refs the rendering
        backend, and the rendering backend indirectly holds on to RemoteDisplayListRecorders through remote image
        buffers in the resource cache. Since RemoteRenderingBackend also strongly refs  GPUConnectionToWebProcess as
        well, this caused the entire GPUConnectionToWebProcess to leak after tearing down the connected web process, if
        the web process ever installed a remote rendering backend for 2D canvas.

        To avoid this cycle, turn RemoteDisplayListRecorder's `m_renderingBackend` into a RefPtr instead of a Ref, and
        clear it out in `stopListeningForIPC()`. This also means that we no longer need a separate boolean flag to
        ensure that `RemoteDisplayListRecorder::stopListeningForIPC()` is idempotent, so we also remove
        `m_isListeningForIPC` altogether.

        RemoteRenderingBackend should not send IPC in the middle of destruction

        Reviewed by Darin Adler.

        Make a couple of minor adjustments to RemoteRenderingBackend (see below for more details). This is necessary in
        order to avoid flaky crashes after fixing bug #232113, after which the RemoteRenderingBackend will no longer be

        Move logic to flush remaining incoming IPC messages in the GPU process out of the destructor, and into
        `stopListeningForIPC()` instead. This is because the act of processing certain stream IPC messages (such as
        CreateImageBuffer or FlushContext) may cause RemoteRenderingBackend to try and send IPC back to the web process.
        However, if RemoteRenderingBackend is in the middle of destruction, it will crash when attempting to do so (when
        attempting to call into IPC::MessageSender).

        To avoid this, we need to do this work earlier, after we've already stopped listening for further IPC messages.

        * GPUProcess/graphics/RemoteRenderingBackend.h:

        Turn `m_remoteDisplayLists` into a regular hash map containing RemoteDisplayListRecorders by their process-
        qualified rendering resource identifiers. Since this map may be modified from different threads, we (1) don't
        want to be using weak pointers here, and (2) need to ensure that access to this table is guarded behind a lock.
        To avoid reference cycles, entries in this table are cleared out when the remote image buffer corresponding to
        each RemoteDisplayListRecorder is released in the GPU process.

        Break the current `isSelectable` flag out into different enum types, which enumerate the reasons why we might

        `-textInteractionGesture:shouldBeginAtPoint:` below if the element has an explicit `-webkit-user-select: none;`,
        and not because of the other reasons (i.e. large element bounds or the fact that we're long pressing editable
        text while not editing).

        This nuance is important in order to continue allowing the loupe gesture (which manifests as a floating caret)
        to begin when long pressing inside a focused a text field.

        RemoteRenderingBackend::CreateImageBuffer should be an async IPC stream message
        https://bugs.webkit.org/show_bug.cgi?id=231970

        Reviewed by Kimmo Kinnunen.

        This patch reverts the changes in r284476, which worked around a race when adding receive queues for newly
        created IPC stream destinations and simultaneously dispatching IPC messages to those destinations. Rather than
        making the IPC message that creates and adds the new image buffer's RemoteDisplayListRecorder synchronous, we
        instead keep that message async and make adjustments to ensure that incoming out-of-stream IPC messages for
        RemoteDisplayListRecorder can always be mapped to an appropriate receive queue. See below for more details.

        * GPUProcess/graphics/RemoteDisplayListRecorder.cpp:
        (WebKit::RemoteDisplayListRecorder::startListeningForIPC):

        Move the main runloop bounce down to `StreamServerConnectionBase::startReceivingMessagesImpl()` instead (to deal
        with the fact that `addMessageReceiveQueue` currently needs to be invoked on the main runloop). This allows us
        to call `StreamServerConnection::startReceivingMessages()` from the processing queue while creating a remote
        image buffer, which (in turn) ensures that incoming out-of-stream messages from the IPC thread will be sent to
        the correct RemoteDisplayListRecorder destination by the time they're dispatched on the work queue thread.

        * GPUProcess/graphics/RemoteRenderingBackend.cpp:
        (WebKit::RemoteRenderingBackend::startListeningForIPC):
        (WebKit::RemoteRenderingBackend::stopListeningForIPC):

        Additionally register a "0-destination" receiver to ensure that all RemoteDisplayListRecorder messages (even
        without pre-existing destinations) will be enqueued on the same IPC stream connection as this remote rendering
        backend.

        (WebKit::RemoteRenderingBackend::createImageBuffer):
        * GPUProcess/graphics/RemoteRenderingBackend.h:
        * GPUProcess/graphics/RemoteRenderingBackend.messages.in:

        Make `CreateImageBuffer` an async stream message once again.

        * Platform/IPC/StreamConnectionWorkQueue.cpp:
        (IPC::StreamConnectionWorkQueue::processStreams):
        * Platform/IPC/StreamConnectionWorkQueue.h:

        Change `m_connections` into a HashCountedSet (from a HashSet), to ensure that the same server connection object
        can be added to and removed from the work queue multiple times, without removing the connection from the map
        early.

        * Platform/IPC/StreamServerConnection.cpp:
        (IPC::StreamServerConnectionBase::startReceivingMessagesImpl):
        (IPC::StreamServerConnectionBase::stopReceivingMessagesImpl):
        * Platform/IPC/StreamServerConnection.h:
        (IPC::StreamServerConnection::startReceivingMessages):
        (IPC::StreamServerConnection::stopReceivingMessages):

        Add new methods to start and stop receiving all messages for a given ReceiverName, regardless of incoming
        destination ID. RemoteRenderingBackend now uses this to register a "catch-all" listener for all
        RemoteDisplayListRecorder messages.

        We used to render audio tracks in process and are now doing rendering in GPU process.
        Current implementation requests data with a fixed chunk size, that we were setting as the max of preferred buffer size and web audio chunk size.
        If we are reading too close to the end of data in AudioSampleDataSource, we will delay reading the data by this buffer size. This triggers delay but allows getting a consistent rendering.
        To reduce delay, we are now using the maximum of web audio chunk size and 10 ms chunk size, as WebRTC tracks are usually manipulating 10 ms chunks.

        Remove the redundant protection ref so it does not cause confusion.
        The protection ref cannot hold the last ref, as that would mean

        WebKit should process-swap for initial navigation of a popup if it has no opener, even if the navigation is
        same-site. Swapping process is not Web-observable here since there is no opener relationship. However, swapping
        processes has benefits here since we don't want to end up with too many tabs sharing the same process.

        This impacts Google Drive where double-clicking a document will open Google Docs in a new tab and in the same
        WebProcess as Google Drive.

        No new tests, updated existing API tests and this is not Web-observable.

        WebKit Managed Notifications: Skeleton NotificationProvider

        Reviewed by Alex Christensen.

        Currently, notification messages route from WebContent to the UI process.

        These tests occasionally fail when we time out while waiting for the pixel buffer to be populated underneath
        `RemoteImageBufferProxy::getPixelBuffer`; this happens because the GPU process sometimes halts (and never
        resumes) while processing stream messages, and consequently never ends up processing the GetPixelBuffer IPC
        stream message that's necessary to populate the shared memory buffer for GetPixelBuffer.

        This, in turn, happens when the IPC stream buffer is about to exhaust all available capacity (i.e. the write
        cursor is nearing the end of the 2MB buffer), and as a result, we send messages that would normally be encoded
        in the IPC stream as out-of-line IPC messages instead, which are received in the GPU process on the IPC thread
        and appended to the receive queue corresponding to the destination ID in `Connection::processIncomingMessage()`.

        If we happen to have sent `RemoteRenderingBackend::CreateImageBuffer(a)` right before exhausting capacity and
        sending out-of-line messages targeting the RemoteDisplayListRecorder corresponding to the newly created image
        buffer `a`, we'll end up with a race condition where the IPC thread may receive the out-of-line messages meant
        for the new remote display list destination *before* the new remote display list has added itself as an IPC
        receive queue by calling into `StreamServerConnection::startReceivingMessages()`.

        In this particular scenario (where we "lose" the race), `Connection::processIncomingMessage` will skip past the
        early return where it would normally find its corresponding receive queue via `m_receiveQueues.get(*message)`,
        and instead falls through to `Connection::SyncMessageState::processIncomingMessage()`, which will attempt to
        dispatch the incoming message to the Connection's client (GPUConnectionToWebProcess). Of course, the
        GPUConnectionToWebProcess isn't aware of how to process this incoming message, so it simply gets dropped. By the
        time the receive queue is added for the new RemoteDisplayListRecorder, we'll observe a ProcessOutOfStreamMessage
        and end up waiting forever for this out-of-line message to be added to the receive queue, but this never ends up
        happening because it has already been received and dropped by GPUConnectionToWebProcess.

        To address the flaky tests in the short term, we work around this issue by making `CreateImageBuffer` a sync
        message, so we guarantee that any subsequent messages sent to the image buffer's RemoteDisplayListRecorder will
        not be dropped. In the (slightly) longer term, we should turn this back into an async stream message, and add a
        mechanism to redirect all receiver-less RemoteDisplayListRecorder messages to a separate queue.

        Reviewed by Sam Weinig.

        When GPU process media handling is enabled, ctx.drawImage(video)
        calls work by sending a NativeImageForCurrentTime message to the GPU
        process, which returns an IOSurface around which a CGImage is created.
        There's no good way to get the color space off the IOSurface, so we
        add a second return argument to NativeImageForCurrentTime to indicate
        the color space used.

        ImageBitmap creates an ImageBuffer for that image to be painted into,
        and for that we also need to know the color space of the video. The
        code that sends NativeImageForCurrentTime and then paints the
        resulting image into the GraphicsContext is further down. So we add
        a separate IPC message that gets the color space of the video's
        current frame. (It would be better if we could avoid a second
        synchronous IPC message call, but either ImageBitmap's scaling and
        cropping code, or the ImageBuffer creation call, would need to be moved
        down into MediaPlayerPrivateRemote::paintCurrentFrameInContext, which
        doesn't seem like the right place for it.)

        GPU process occasionally crashes under `StreamConnectionWorkQueue::processStreams()` in layout tests
        https://bugs.webkit.org/show_bug.cgi?id=231897

        Reviewed by Simon Fraser.

        Certain layout tests (e.g. in `LayoutTests/compositing`) currently cause the GPU process to crash on the remote
        rendering backend thread ("RemoteRenderingBackend work queue") in `StreamConnectionWorkQueue::processStreams()`.
        This happens because the `dispatch()` call to delete cached resources underneath `~RemoteRenderingBackend()`
        may fire after the destructor is finished running (thereby destroying `m_workQueue` itself). This leaves the
        stream work queue in a bad state and causes various crashes when the function is eventually dispatched.

        Since StreamConnectionWorkQueue is already ThreadSafeRefCounted, it doesn't make sense to directly store
        StreamConnectionWorkQueue as a member of RemoteRenderingBackend; to fix these crashes, we make `m_workQueue` on
        RemoteRenderingBackend a strong Ref, and additionally make `StreamConnectionWorkQueue::processStreams()` protect
        itself to avoid destroying the work queue in the middle of processing.

        Web process occasionally crashes under `RemoteDisplayListRecorderProxy::recordRestore()`
        https://bugs.webkit.org/show_bug.cgi?id=231900

        Reviewed by Tim Horton.

        It's apparently possible for a RemoteImageBufferProxy in the web process to outlive RemoteRenderingBackendProxy.
        Before the IPC stream refactoring in r284079, we were robust against this possibility because
        RemoteImageBufferProxy checked for a null rendering backend in `canAppendItemOfType` and returned `false`, which
        prevented us from trying to call into the rendering backend. However, I accidentally omitted this null check
        in the new RemoteDisplayListRecorderProxy, which currently assumes that `m_renderingBackend` is always non-null
        when sending any IPC stream messages.

        Fix this crash by restoring the null check for the weak `m_renderingBackend` pointer. I only observed this crash
        once locally and, unfortunately, haven't been able to come up with a test case that consistently reproduces it.

        Implement two new methods on JSIPCStreamClientConnection: `sendMessage()` and `sendSyncMessage()`, which can be
        used to send IPC messages through the IPC stream client connection. To do this, we match the existing methods of
        the same names on JSIPC by creating a message encoder and sending it over the stream connection's IPC
        connection, effectively treating all IPC messages as out-of-line.

        In the future, this should be changed so that we only try to send out-of-line messages if the message itself is
        not stream encodable; for the time being, this at least allows us to fix the failing API test, and still makes
        it possible to test sending arbitrary IPC through the connection stream, such that we'll be able to exercise
        WebGL and display list IPC via these special JS IPC bindings.

        WebKit Managed Notifications: Skeleton NotificationProvider.

        Reviewed by Alex Christensen.

        No new tests (No behavior change yet)

        Currently WebNotificationManagerProxy manages dispatching out stuff to the NotificationProvider SPI
        that - for example - Safari on Mac implements.
        
        The interface between the ManagerProxy and the Provider is already the perfect way to add an alternative behavior.
        
        This introduces the skeleton class of an alternative NotificationProvider that will eventually implement 
        WebKit-managed notifications.
        
        While under development it will have a global runtime switch so we can A/B test between the client-managed and 
        WebKit-managed notifications. That switch would eventually be replaced by full compile-time behavior which would
        be decided by a shipping vendor.
        
        Note: This patch enables the new flag BUILT_IN_NOTIFICATIONS to get the new mechanisms building, but that flag by
        itself doesn't expose Notifications interfaces in WebCore.
        That will still require enabling NOTIFICATIONS separately.

        [JS IPC] Make it possible to establish a stream connection using the JS IPC testing API
        https://bugs.webkit.org/show_bug.cgi?id=231710

        Reviewed by Tim Horton.

        Work towards fixing IPCTestingAPI.CanReceiveIPCSemaphore and IPCTestingAPI.CanReceiveSharedMemory, which broke
        after I refactored RemoteRenderingBackend to be a IPC stream message receiver (instead of a standard IPC message
        receiver). To achieve this, we introduce two new JS wrapper objects to encapsulate an IPC stream client
        connection, as well as the stream buffer used to service that connection.

        This allows us to establish a streaming IPC connection from the web process to the GPU process via JS IPC API,
        like so:

        ```
        const bufferSize = 1 << 16;
        const streamConnection = IPC.createStreamClientConnection('GPU', bufferSize);
        IPC.sendMessage('GPU', 0, IPC.messages.GPUConnectionToWebProcess_CreateRenderingBackend.name, [
            { type: 'RemoteRenderingBackendCreationParameters', 'identifier': 123, 'pageProxyID': IPC.webPageProxyID, 'pageID': IPC.pageID },

        [WKWebView _loadServiceWorkerURL] ends up lowercasing URL host
        https://bugs.webkit.org/show_bug.cgi?id=231742

        Reviewed by Timothy Hatcher.

        [WKWebView _loadServiceWorkerURL] ends up lowercasing URL host. While I don't think it is technically wrong
        (hosts should not be case-sensitive), it can be confusing.

        The reason this was happening is that I was using SecurityOriginData::fromURL(url).toString() to extract the
        URL's scheme/host/port and SecurityOriginData::fromURL() lowercases the scheme and host. I am now using
        URL::protocolHostAndPort() instead, which does not have this side effect and is actually more efficient.

        No new tests, extended existing API test.

        [GTK] Opening emoji chooser crashes UI process with GTK 3.24.30

        Instead of providing a copy of the emoji chooser widget, use GLib's
        introspection features and a little sprinkle of knowledge about how
        GTK works in order to obtain the type code of the GtkEmojiChooser
        widget included with GTK. This ensures that a working widget is
        always used, regardless of the current GTK version.

        Several SPI classes in VisionKitCore are going to be renamed to be prefixed with VKC- rather than VK-, with a
        `@compatibility_alias` for the existing SPI names. Refactor Live Text support in WebKit to be both binary and
        source compatible with this future version of VisionKitCore, by checking for the existence of both class names

        Use the helper functions declared in TextRecognitionUtilities.h, instead of using PAL softlinking directly. We
        also refactor this code to pass a CGImageRef instead of a UIImage when initializing the image analyzer request,
        such that the helper functions can work across macOS and iOS.

        Also rename `createImageAnalysisRequest` to `createImageAnalyzerRequest` for consistency with the class name.

        WebGL video texture upload is very slow due to excessive transfer of the video pixel buffer
        https://bugs.webkit.org/show_bug.cgi?id=231425

        Reviewed by Youenn Fablet.

        Typical WebGL content requests the videos to be uploaded to a texture
        once per render loop update, even though the video has not changed.
        The video pixel buffer is slow to transfer across IPC. It should be transferred
        only when it has changed.

        MediaPlayerPrivateAVFoundationObjC and MediaPlayerPrivateMediaSourceAVFObjC hold
        the last requested pixel buffer ref. They will update it or discard it only
        when pixelBufferForCurrentTime() is called.

        Cache the pixel buffer to MediaPlayerPrivateRemote (GPUP side proxy)
        Cache the pixel buffer to RemoteMediaPlayerProxy (WebP side proxy)

        The caches increase the total memory use only during the duration
        of the call, since after the ref has been updated, it refers
        to the one always held in the original objects (MediaPlayerPrivateAVFoundationObjC
        and MediaPlayerPrivateMediaSourceAVFObjC)

        No new tests, fixes a perf regression wrt GPUP media.

        [GPU Process] Use IPC streaming for concurrent display list processing
        https://bugs.webkit.org/show_bug.cgi?id=230860
        rdar://83438038

        Reviewed by Tim Horton.

        This patch rebuilds the concurrent display list architecture in the web and GPU processes on top of the
        streamable IPC connections currently used by WebGL in the GPU process. See below for more details.

        There should be no change in behavior.

        * GPUProcess/GPUConnectionToWebProcess.cpp:
        (WebKit::GPUConnectionToWebProcess::createRenderingBackend):

        Pass a StreamConnectionBuffer from the web process to the GPU process when constructing
        RemoteRenderingBackend; this serves as the pool of shared memory used to store streaming IPC messages sent from
        the web process to the GPU process. I've (somewhat arbitrarily) chosen the size of this StreamConnectionBuffer
        to match WebGL's connection buffer, though this can be tuned as needed. In a future patch, we may also want to
        implement a mechanism for starting out with a small connection buffer, and growing it by successively larger
        segments as needed.

        * GPUProcess/GPUConnectionToWebProcess.h:
        * GPUProcess/GPUConnectionToWebProcess.messages.in:
        * GPUProcess/cocoa/GPUProcessCocoa.mm:
        (WebKit::GPUProcess::additionalStateForDiagnosticReport const):

        Add a FIXME for re-introducing diagnostic state logging when using streamable IPC.

        * GPUProcess/graphics/RemoteDisplayListRecorder.cpp:
        (WebKit::RemoteDisplayListRecorder::RemoteDisplayListRecorder):
        (WebKit::RemoteDisplayListRecorder::startListeningForIPC):
        (WebKit::RemoteDisplayListRecorder::stopListeningForIPC):

        Add and remove the remote display list as a destination on the RemoteRenderingBackend's stream connection. Note
        that the synchronous dispatch to the main thread here is necessary to maintain the ordering of out-of-stream IPC
        messages that may have been received on the IPC thread.

        * GPUProcess/graphics/RemoteDisplayListRecorder.h:
        (WebKit::RemoteDisplayListRecorder::create):
        (WebKit::RemoteDisplayListRecorder::handleItem):
        * GPUProcess/graphics/RemoteImageBuffer.h:
        (WebKit::RemoteImageBuffer::RemoteImageBuffer):
        (WebKit::RemoteImageBuffer::apply): Deleted.

        Introduce `m_remoteDisplayList` to RemoteImageBuffer, and remove some logic for applying display list items that
        is no longer necessary.

        * GPUProcess/graphics/RemoteRenderingBackend.cpp:
        (WebKit::RemoteRenderingBackend::create):
        (WebKit::RemoteRenderingBackend::RemoteRenderingBackend):

        Set up the IPC stream connection and stream connection work queue, and immediately send a wakeup semaphore back
        to the web process.

        (WebKit::RemoteRenderingBackend::startListeningForIPC):
        (WebKit::RemoteRenderingBackend::~RemoteRenderingBackend):
        (WebKit::RemoteRenderingBackend::stopListeningForIPC):

        Add a mechanism to immediately tell all `m_remoteDisplayLists` to stop listening for streaming IPC messages when
        the owning RemoteRenderingBackend stops listening.

        Remove logic for coordinating wakeups and shared display list item buffers in the GPU process.

        * GPUProcess/graphics/RemoteRenderingBackend.h:

        Subclass IPC::StreamMessageReceiver. In this new concurrent display list model, RemoteRenderingBackend serves
        as a streaming IPC destination alongside each RemoteDisplayListRecorder in the GPU process; all messages
        previously sent to the RemoteRenderingBackend as normal IPC are now sent through the connection stream (though
        some must be marked as non-stream-encodable).

        Delete more logic related to concurrent display lists.

        * GPUProcess/graphics/RemoteRenderingBackend.messages.in:

        Make RemoteRenderingBackend a stream message receiver.

        * GPUProcess/graphics/RemoteRenderingBackendCreationParameters.h:
        (WebKit::RemoteRenderingBackendCreationParameters::encode const):
        (WebKit::RemoteRenderingBackendCreationParameters::decode):

        Remove the IPC::Semaphore here, that was previously used for quick GPU process wakeups. This semaphore is no
        longer needed because we always use IPC::Semaphore for waking the GPU process when using streaming IPC.

        * GPUProcess/graphics/RemoteResourceCache.h:
        * WebProcess/GPU/graphics/RemoteImageBufferProxy.h:

        Make the RemoteImageBufferProxy template class directly subclass ConcreteImageBuffer instead of
        DisplayList::ImageBuffer; additionally, introduce a `RemoteDisplayListRecorderProxy m_remoteDisplayList` here,
        which we use as our drawing graphics context.

        Send all IPC messages to RemoteRenderingBackend in the GPU process through the stream connection, instead of
        using standard IPC messages. This guarantees ordering when receiving cached resources.

        backend.

        Move these interface declarations out of this implementation file, and into PAL instead, but only if we're not

        workaround was only added to ensure source and binary compatibility with older versions of the internal macOS

        Scrolling thread animations need to commit layers on the scrolling thread

        Re-land r284022 with a fix in WebPageProxy to avoid non-balanced calls to
        setDisplayLinkForDisplayWantsFullSpeedUpdates().
        
        Scroll animations were running on the scrolling thread (in that the timers were firing on
        that thread), but the scrolling thread wasn't changing layer positions, so those animations
        weren't smooth.

        This happened because of an existing assumption that we only commit layer changes on the
        scrolling thread in response to wheel events; the machinery around
        ThreadedScrollingTree::displayDidRefresh() was all gated on having recently received a wheel
        event.

        To fix this we need to communicate back to the UI process when there are active scroll
        animations running. The ScrollingTree already tracks this, and the virtual
        hasNodeWithAnimatedScrollChanged() on ScrollingCoordinator is called for it. To get this to
        the UI process on macOS, subclass ScrollingCoordinatorMac in WebKit2 and override
        hasNodeWithAnimatedScrollChanged() to call into WebPage, which then IPCs to WebPageProxy.
        This ends up calling setDisplayLinkForDisplayWantsFullSpeedUpdates() so that know to IPC
        displayDidRefresh to EventDispatcher off the main thread (as we do for wheel events).

        Scroll animations are still based on a 60Hz timer, but in future should be driven by
        displayDidRefresh() notifications.

        Reviewed by Per Arne Vollan.

        This patch adopts a set of suggested improvements made by Apple's Sandbox team:

        1. Minimize regex usage
        2. Remove duplicate rules
        3. Remove 'defined?' checks for the many things that are supported in all WebKit target OSes.

        These will simplify the rules, and should provide some launch time improvement.

        [GPU Process] Unique RenderingResourceIdentifiers Part 5: Migrate RemoteResourceCache to QualifiedRenderingResourceIdentifier
        https://bugs.webkit.org/show_bug.cgi?id=231407
        <rdar://problem/84010479>

        Reviewed by Said Abou-Hallawa.

        This pushes QualifiedRenderingResourceIdentifier down into RemoteResourceCache, but doesn't go all the way.
        This patch augments RemoteResourceCache's API to accept QualifiedRenderingResourceIdentifiers, and also
        migrates RemoteResourceCache::m_resourceUseCounters to use QualifiedRenderingResourceIdentifiers.

        RemoteResourceCache::m_imageBuffers, RemoteResourceCache::m_nativeImages, and RemoteResourceCache::m_fonts
        are WebCore typedefs, and are passed to WebCore's display list replaying code, but that code should have no
        notion of process identifiers. Therefore, in order to make those members hold data that WebCore doesn't
        understand, I'm going to have to wrap an opaque class around them and pass that class around instead of
        the raw HashMaps. I'll do that in another patch.

        No new tests because there is no behavior change.

        [GPU Process] Unique RenderingResourceIdentifiers Part 5: Migrate RemoteResourceCache to QualifiedRenderingResourceIdentifier

        This pushes QualifiedRenderingResourceIdentifier down into RemoteResourceCache, but doesn't go all the way.
        This patch augments RemoteResourceCache's API to accept QualifiedRenderingResourceIdentifiers, and also
        migrates RemoteResourceCache::m_resourceUseCounters to use QualifiedRenderingResourceIdentifiers.

        RemoteResourceCache::m_imageBuffers, RemoteResourceCache::m_nativeImages, and RemoteResourceCache::m_fonts
        are WebCore typedefs, and are passed to WebCore's display list replaying code, but that code should have no
        notion of process identifiers. Therefore, in order to make those members hold data that WebCore doesn't
        understand, I'm going to have to wrap an opaque class around them and pass that class around instead of
        the raw HashMaps. I'll do that in another patch.

        No new tests because there is no behavior change.

        Introduce RemoteDisplayListRecorderProxy and RemoteDisplayListRecorder
        https://bugs.webkit.org/show_bug.cgi?id=231484

        Reviewed by Simon Fraser.

        Introduce two new classes that house most of the logic for propagating display list items from the web content
        process to the GPU process. RemoteDisplayListRecorderProxy is a subclass of DisplayList::Recorder that records
        each item by sending it to the GPU process through a stream connection, which will be added to
        RemoteRenderingBackendProxy in a subsequent patch. The RemoteDisplayListRecorderProxy will be managed by
        RemoteImageBufferProxy in the web process. RemoteDisplayListRecorder acts as the streaming IPC destination in
        the GPU process, and handles the incoming display list items by applying them to the platform graphics context.

        For most of these display list items, we can propagate them to the GPU process by sending each display list
        item's constructor arguments as separate IPC arguments. In a future patch, we should add support for encoding
        the following display list items in the same way:

        - SetInlineFillColor
        - SetInlineStrokeColor
        - SetState
        - SetLineDash
        - DrawGlyphs
        - DrawLinesForText
        - FillRectWithGradient

        For now, the above display list items are encoded and decoded as whole items. While there's no practical
        disadvantage to implementing it this way, it would be nice to make it consistent.

        Smooth-scroll animations should run in the UI process on iOS
        https://bugs.webkit.org/show_bug.cgi?id=204936

        Reviewed by Tim Horton.

        Implement animated scrolls in the UI process for UI-side compositing. The scrolling tree
        decoded in the UI process has a RequestedScrollData with the 'animated' flag. This is
        processed by handleScrollPositionRequest() as normal.

        ScrollingTreeOverflowScrollingNodeIOS::startAnimatedScrollToPosition() responds by calling
        through to the delegate, which simply calls -[setContentOffset:animated:YES] on the
        UIScrollView.

        Main frame scrolls are a little different because the programmatic scroll needs to be
        handled after layer tree commits; leverage the existing
        RemoteScrollingCoordinatorProxy::scrollingTreeNodeRequestsScroll() code, but clean it up to
        share the RequestedScrollData type, and have commitScrollingTreeState() return
        std::optional<RequestedScrollData> instead of storing a pointer to a struct on the stack as
        it did before. The various requestScroll() functions take a ScrollIsAnimated flag which
        turns into  -[setContentOffset:animated:YES] in WKWebView.

        Ensure that animated scrolls will run on the scrolling thread
        https://bugs.webkit.org/show_bug.cgi?id=231441

        Reviewed by Tim Horton.

        On macOS, scrolling tree commits run on the main thread (holding a lock), so we can't start
        scroll animations directly inside the commit because then they will run on the main thread.

        Fix by adding ScrollingTree::didCommitTree(), and having ThreadedScrollingTree override it
        to bounce to the scrolling tree to start animations. We also have to intercept requested scroll
        position updates via ScrollingTree::scrollingTreeNodeRequestsScroll(); ThreadedScrollingTree
        uses this to put pending animations into m_nodesWithPendingScrollAnimations.

        Now that ScrollingTreeScrollingNode::commitStateAfterChildren() responds to
        RequestedScrollPosition changes by calling handleScrollPositionRequest(), we can remove code
        in derived classes that did the same thing.

        Not yet tested because animated scrolls don't yet get to the scrolling tree.

        Plumb "animated scroll did end" back from the scrolling tree
        https://bugs.webkit.org/show_bug.cgi?id=231412

        Reviewed by Tim Horton.

        Before we can enable async animated scrolls, we have to get the "did end" notification back
        from the scrolling thread/UI process in order to clear the ScrollAnimationStatus on
        ScrollableArea.

        The scroll animations are run by the ScrollingEffectsController owned by
        ScrollingTreeScrollingNodeDelegateMac/ScrollingTreeScrollingNodeDelegateNicosia. Their
        didStopAnimatedScroll() implementations call through the ScrollingTreeScrollingNde to the
        ScrollingTree, which enqueues ScrollUpdate just as we do for scroll position changes.

        ScrollUpdate is enhanced to contain an 'updateType' with a AnimatedScrollDidEnd value. When
        this is received by AsyncScrollingCoordinator it clears the ScrollAnimationStatus on the
        relevant FrameView/RenderLayerScrollableArea.

        With UI-side compositing, AnimatedScrollDidEndForNode is an IPC message back to
        RemoteScrollingCoordinator.

        Not yet tested because async animated scrolls are not enabled.

        [GPU Process] Unique RenderingResourceIdentifiers Part 2: Unroll PendingWakeupInformation::arguments
        https://bugs.webkit.org/show_bug.cgi?id=231403

        Reviewed by Wenson Hsieh.

        We're in the process of replacing RenderingResourceIdentifiers in the GPU process with
        QualifiedRenderingResourceIdentifier. Unfortunately, PendingWakeupInformation holds
        a GPUProcessWakeupMessageArguments which itself holds a RenderingResourceIdentifiers.
        PendingWakeupInformation is part of the GPU process, so it needs to migrate to 
        QualifiedRenderingResourceIdentifier, but GPUProcessWakeupMessageArguments is the type
        of the arguments to the WakeUpAndApplyDisplayList message, so it can't hold a
        QualifiedRenderingResourceIdentifier.

        So, the solution is to unroll PendingWakeupInformation::arguments, and hoist its fields
        directly into the PendingWakeupInformation. That way, PendingWakeupInformation can be
        updated to use QualifiedRenderingResourceIdentifier, without affecting
        the WakeUpAndApplyDisplayList message.

        No new tests because there is no behavior change.

        <rdar://problem/83920780>

        Reviewed by Chris Dumez.

        Each web process creates its own RenderingResourceIdentifiers. Because the GPU process
        can service multiple web processes, these identifiers can collide in the GPU process.
        This is somewhat error prone, and might cause us to make a mistake in the future and
        introduce a bug which lets one web process see another web process's resources (which
        would be mega bad).

        The goal of this project is to treat RenderingResourceIdentifiers in the GPU process
        as a tuple of (the identifer we got from the web process, the process identifier of
        the web process). This way, the tuples uniquely identify a resource across the entire
        GPU process. Doing it this way makes it less likely that we'll make a mega bad mistake
        in the future.

        This patch is the first step: It introduces the QualifiedRenderingResourceIdentifier
        type, which holds the tuple described above, and makes all the GPU process message
        receivers immediately turn any RenderingResourceIdentifiers they received from the
        web processes into QualifiedRenderingResourceIdentifiers. Not only do the identifiers
        immediately get packed, but each message receiver now has an implementation function
        which only accepts the QualifiedRenderingResourceIdentifier, so we can't make a
        mistake and use the unpacked one accidentally.

        Because this patch is just the first step, the QualifiedRenderingResourceIdentifiers
        get unpacked eagerly, and the inner logic of the GPU process is unaffected. The
        subsequent two patches will push the QualifiedRenderingResourceIdentifiers deeper
        into the guts of the GPU process, eventually to the point where
        RenderingResourceIdentifiers are never used there.

        StreamMessageReceivers. This has the disadvantage of performing a vtable lookup with each message dispatch, but
        I did not measure this to be a significant performance regression on any of the canvas subtests in MotionMark.

        Reviewed by Simon Fraser.

        Make it possible to avoid sending the wakeup message in StreamClientConnection, until some configurable number
        of messages have been queued up. This allows us to avoid triggering excessive wakeups in the GPU Process when
        using streaming IPC for display lists in the Canvas Lines subtest in MotionMark, which exercises sending a
        massive, constant stream of cheap drawing commands to the GPUP.

        By default, this hysteresis remains at 0, which means that we'll continue to immediately send GL commands to the
        GPU Process when using GPU Process for WebGL. In a future patch, I intend on defaulting to a small hysteresis
        (i.e. ~256) for 2D canvas and DOM rendering.

        When sending a normal (non-blocking) stream message, if the wakeup hysteresis count is non-zero, avoid

        (`m_wakeUpMessageHysteresis`).

        (IPC::StreamClientConnection::trySendSyncStream):

        When sending a sync message, we always want to immediately flush out any pending wakeup message regardless of

        When computing time out deadlines for IPC messages, the time granularities (on the order of hundreds of
        milliseconds) are many, many orders of magnitude greater than the granularity of ApproximateTime; this makes it
        much cheaper to use ApproximateTime instead of MonotonicTime when computing these deadlines, which significantly
        improves performance in the case where we're streaming high volumes of IPC messages.

        Additionally, in the case where the timeout duration is infinite, we can avoid asking for the current time
        altogether, and simply use `ApproximateTime::infinity()`.

        SimpleArgumentCoder for all of these. We also add new `DEFINE_SIMPLE_ARGUMENT_CODER_FOR_(HEADER|SOURCE)` macros

        [iOS] Transcode videos selected from UIImagePickerController
        https://bugs.webkit.org/show_bug.cgi?id=230639
        rdar://79665678

        Reviewed by Tim Horton.

        File inputs on iOS allow users to choose images/videos from the system
        photo picker, using UIImagePickerController. In single selection mode,
        UIImagePickerController transcodes the selected video to H.264. However,
        in multiple selection mode, video is not transcoded and is left in its
        original format.

        Today, videos on most iOS devices are encoded with HEVC by default.
        However, some sites, such as Twitter, only accept H.264 encoded video.
        Thus, the current video upload behavior is problematic, as users may be
        unable to upload video.

        Unfortunately, the photo picking functionality of UIImagePickerController
        is deprecated. The best solution would be to adopt PHPickerViewController,
        the replacement API, which performs transcoding when retrieving selected
        items (regardless of single/multiple selection). However,
        PHPickerViewController currently lacks other functionality that WebKit
        requires, preventing adoption.

        Consequently, the short term solution is to transcode the videos in
        WebKit, ensuring H.264 encoded video is always provided to sites. See
        below for implementation details.

        Introduce WKFileUploadMediaTranscoder to manage transcoding of videos
        and the display of progress UI. Transcoding is performed serially
        (one video at a time), but occurs off the main thread.

        (-[WKFileUploadMediaTranscoder start]):

        Begin transcoding. Run a timer to update the progress UI, as
        AVAssetExportSession does not provide progress updates on its own.

        The progress UI is implemented using PUActivityProgressController, to
        match system Photos UI.

        (-[WKFileUploadMediaTranscoder _processItemAtIndex:]):

        Transcode a single video, using AVAssetExportSession. If transcoding
        fails for any reason, the original video is used as a fallback.
        Transcoding can also be cancelled using the progress UI, in which case
        no more videos are processed.

        Add SPI to launch a service service worker in a WKWebView and expose service worker to injected bundle
        https://bugs.webkit.org/show_bug.cgi?id=231045
        <rdar://problem/83744069>

        Reviewed by Geoff Garen.

        Add new [WKWebView loadServiceWorker:(NSURL *)] to load a service worker in a web view. When called,
        it causes us to create a page with HTML start registers the service worker with the provided URL.

        The service worker in question will differ slightly from usual service workers in that:
        - The service worker URL doesn't need to be HTTP/HTTPS. In particular, a custom scheme (with corresponding
          custom scheme handler) can be used.
        - The service worker will always run in the WKWebView's associated WebProcess (which can be controlled via
          WKWebViewConfiguration._relatedWebView).
        - The service worker will run on the main thead
        - The service worker is not persistent, meaning that it will not be saved to disk, unlike regular service
          workers.
        - The service worker's global object will be exposed to the injected bundle via a new serviceWorkerGlobalObjectIsAvailableForFrame
          function call on WKWebProcessPlugInLoadDelegate. The provided Frame will be the WKWebView's main frame.
        - The service worker will be unregistered & exit as soon as its WKWebView gets closed / deallocated.

        To make the service worker more usable via the injected bundle API, the following changes were made too:
        - [WKWebProcessPlugInFrame lookUpFrameFromJSContext:] will return the WKWebView's main frame when passed in
          that view's service worker context.
        - A new [WKWebProcessPlugInFrame jsContextForServiceWorkerWorld:(WKWebProcessPlugInScriptWorld *)] SPI was
          added to get the service worker's JS context from the view.

        I added an API test that launches such a service worker, makes sure the injected bundle gets notified on
        the main thread of the service worker global object and that it can script it. The test also makes sure
        the _relatedWebView SPI works to force a service worker into another view's process. It also tests that
        [WKWebProcessPlugInFrame lookUpFrameFromJSContext:] and [WKWebProcessPlugInFrame jsContextForServiceWorkerWorld:(WKWebProcessPlugInScriptWorld *)]
        work as expected. Finally, it makes sure the service worker properly exits when the view gets closed.

        https://bugs.webkit.org/show_bug.cgi?id=231106

        Reviewed by Geoffrey Garen.

        r275455 added a dispatch_async() which captures a Ref<> to a WebProcessProxy. This may cause the WebProcessProxy to
        outlive its WebProcessPool (prewarmed WebProcessProxies to not ref their WebProcessPool), which is not supported.
        We could fix the crash by also capturing a Ref<> to the WebProcessPool in the lambda. However, in this particular
        instance, it does not seem useful to extend the lifetime of the WebProcessProxy / WebProcessPool so I opted to use
        a WeakPtr.

        No new tests, covered by existing API test crashing in debug.

        Use DYLD_FRAMEWORK_PATH instead of DYLD_VERSIONED_FRAMEWORK_PATH on Safari Big Sur
        https://bugs.webkit.org/show_bug.cgi?id=231058

        Reviewed by David Kilzer.

        Modify the DYLD environment variable that is used when compiling with staged frameworks.
        We want to use DYLD_VERSIONED_FRAMEWORK_PATH to define the search path of the frameworks
        for DYLD because this makes launching Safari and its child processes faster. However,
        on Apple Silicon Big Sur using that environment variable does not work and results in Safari
        loading frameworks from the System folder rather than from the StagedFrameworks/Safari
        folder, this is because dyld on M1 does not look up that variable properly. To make sure
        we actually load the frameworks from the desired location, we need to use DYLD_FRAMEWORK_PATH
        instead, this makes dyld perform more stat() calls than usual to link the frameworks hence
        why we prefer the other variable, but this is the only way to workaround the issue in
        Big Sur on M1. In Monterey and above, this bug will be fixed in dyld so we only need this
        variable before macOS 11.

        Override OTHER_LDFLAGS_VERSIONED_FRAMEWORK_PATH_YES based on SDK and architecture to use
        DYLD_FRAMEWORK_PATH instead of DYLD_VERSIONED_FRAMEWORK_PATH when building for macOS 11 and arm64.

        PCM: Take app bundle ID into consideration when matching triggering events with pending clicks
        https://bugs.webkit.org/show_bug.cgi?id=230778
        <rdar://problem/83516528>

        Reviewed by Alex Christensen.

        https://commits.webkit.org/r282884 added app bundle IDs to unattributed
        and attributed clicks in PCM. This patch makes sure we take those IDs
        into consideration in PCM::Database::attributePrivateClickMeasurement().

        A lot of the WebKit part is:
        - Piping through app bundle IDs from the network session to the PCM
            database where the ID will be matched against stored app bundle IDs.
        - Piping through test configuration for app bundle ID.

        The real change is in PCM::Database which is explained below.

        Reviewed by Devin Rousso.

        Add new testing API for evaluating script expressions in the context of a
        tab created by _WKInspectorExtension. For the most part, this is implemented
        in the same way as the -evaluateScript: method, but the script is evaluated
        within the Web Inspector frontend itself rather than in the inspected page.

        To avoid CSP issues, the actual evaluation is performed on subframes using a
        new InspectorFrontendHost method which takes an <iframe> and script source.

        Along the way, tweak Web Inspector's CSP policy to allow loading images from
        custom URL schemes as specified using _WKInspectorConfiguration. This is so
        that tab icons from the test-resource: scheme can be loaded in the main frame
        of Web Inspector's WKWebView under testing situations.

        We recently added a bundleID column to PCM tables. We want to make
        sure entries with different bundleIDs do not override each other,
        so we should make it a part of the unique constraint on both PCM
        tables that contain it. This requires creating new tables and
        migrating existing data to them. Luckily this code already exists
        in the ITP database, and we can just move it to the shared
        DatabaseUtilities class.

        When using an HTTPS proxy, the HTTP connection cache key used for connection coalescing in
        CFNetwork includes the User-Agent (<rdar://problem/59434166>). This means we should also
        include it in the preconnect cache key. Otherwise, we might delay the main resource load on
        preconnect unnecessarily in cases where the User-Agent mismatches and the preconnect gets
        thrown away. This can happen if (for instance) a page is force-loaded into desktop or mobile
        mode on iOS, which causes a UA change after the call to decidePolicyForNavigationAction.

        Make it possible to use `IPC::StreamConnectionEncoder` to encode display list items (and their members) in an

        These WebCore argument coders are also currently incompatible with StreamConnectionEncoder, since they are non-
        templated (and thus only work with IPC::Encoder). Since these are all encodable as POD types, we can just use
        SimpleArgumentCoder for all of these. We also add a new `DEFINE_SIMPLE_ARGUMENT_CODER` macro to make this code a
        bit easier to read.

        Change from ENABLE(RUBBER_BANDING) to HAVE(RUBBER_BANDING)
        https://bugs.webkit.org/show_bug.cgi?id=230583

        Reviewed by Tim Horton.

        RUBBER_BANDING is not a feature we'll ever turn off on macOS, and it was only ever enabled
        for that platform. However, it's also used in some cross-platform code, so
        HAVE(RUBBER_BANDING) makes more sense for that use.

        Also remove ENABLE(RUBBER_BANDING) #ifdefs from inside PLATFORM(MAC) code.

        It has been replaced by sendWithAsyncReply.

        This last use can't really be replaced by sendWithAsyncReply because the CallbackIDs are sent, then further encoded
        in RemoteLayerTreeTransaction::encode/decode which you can't really do with a CompletionHandler.  But we can replace

        When opening a UDP socket, check whether it is a NAT64 IPv4 address.
        In that case, we cannot bind it like we used to do with the sockets API.
        Instead use "0.0.0.0".
        Manually tested.

        Some URLs allow to call getUserMedia but do not have origins, like custom scheme URLs.
        In that case, the attribution status call was failing previously as we were not able to get a visible name to provide.
        We mimick what we are doing for the default prompt by using the visible application name if the origin is not available.
        Since we do the system attribution in GPUProcess, we now send the visible name to GPUProcess when creating it.

        Manually tested.
        We do not have system status attributon on MacOS or simulator so we cannot test it automatically.

        [Cocoa] Videos sometimes don't render when loaded in the GPU process

        The media players choose what type of video output to create based on whether
        or not the renderer can support accelerated rendering. We were only pushing
        this state to the GPU process when the renderer changed to require backing, but
        that state was lost if that transition happened before the AVFoundation-backed
        media player was created. Change this to push the current state from the web process
        when a remote media player is created, and again whenever its readyState changes.

        We haven't figured out how to reliably reproduce this, so https://webkit.org/b/230500
        tracks figuring that out and creating a test.

        https://bugs.webkit.org/show_bug.cgi?id=230468

        Reviewed by Tim Horton.

        `createShareableBitmap` currently only returns a non-null image bitmap for image renderers that have cached
        images; notably, this omits video elements. For use in future patches, we should allow this helper function to
        handle video elements by snapshotting the current frame of the video.

        WebKit::WebProcessPool should use a weak observer with CFNotificationCenter

        <rdar://problem/83067708>

        Reviewed by Darin Adler.

        To fix the bug, implement an Objective-C class named
        WKProcessPoolWeakObserver which contains an instance variable
        holding a WeakPtr<WebProcessPool>, and tell CFNotificationCenter
        to hold a weak reference to WKProcessPoolWeakObserver.

        Since WKProcessPoolWeakObserver is self-contained within the
        source file, it uses the NS_DIRECT_MEMBERS attribute since it
        does not require the overhead of dynamic Objective-C method
        dispatch.

        ShareableBitmap create a CGBitmap with a color space matching the
        source NativeImage, if that is an RGB-based color space, or extended

        [macOS] Avoid computing post-layout EditorState data unless necessary

        <rdar://problem/83078713>

        Reviewed by Devin Rousso.

        Add a new codepath on macOS that allows us to entirely avoid post-layout EditorState computation in the case
        where it's not needed for anything; in particular, unless the text touch bar may be presented or the UI delegate
        implements the `-webView:didChangeFontAttributes:` method, the post-layout portion of EditorState is not needed
        at all.

        See below for more details.

        (WebKit::WebPageCreationParameters::decode):
        * Shared/WebPageCreationParameters.h:

        Plumb a bit indicating whether user interaction is required in order to show the text touch bar. See

        When computing `EditorState.isContentEditable`, use VisibleSelection's `hasEditableStyle` method instead of
        `isContentEditable`. Unlike the latter, the former does not trigger style resolution.

        (WebKit::WebPage::didStartPageTransition):

        Make a slight adjustment to only set the `m_hasEverFocusedElementDueToUserInteractionSincePageTransition` bit if
        the user is actually interacting with text form control or editable element. This allows us to still avoid
        computing post-layout editor state data in cases where the user has clicked on non-editable elements on the
        page, such that text editing controls in the touch bar are still not being shown.

        (WebKit::WebPage::didChangeSelectionOrOverflowScrollPosition):
        (WebKit::WebPage::sendEditorStateUpdate):

        Don't bother scheduling another post-layout EditorState in the case where post-layout data is missing, but we're
        avoiding post-layout data computation altogether due to `shouldAvoidComputingPostLayoutDataForEditorState`
        returning `true`.

        Rename this to `requiresPostLayoutDataForEditorState`, to avoid some confusion with the new method,
        `shouldAvoidComputingPostLayoutDataForEditorState`. The former is a way for platforms to indicate that post-
        layout data *must* be included, even if layout is not up to date yet upon computing the EditorState. The latter
        is a way for platforms to indicate that we can completely avoid all post-layout editor state computation,
        regardless of whether or not layout is up to date.

        By default, if both of the above methods return `false`, we compute and include post-layout data only if layout
        is up-to-date when computing the EditorState, and schedule a subsequent "full" EditorState update after the
        next rendering update in the case where layout was *not* up-to-date already (indicated by the EditorState's
        `isMissingPostLayoutData` flag).

        <rdar://79562514>

        Reviewed by Brady Eidson.

        When the SerializedScriptValue contains BlobURLs, IDBTransaction::putOrAddOnServer()
        calls SerializedScriptValue::writeBlobsToDiskForIndexedDB() before sending the
        WebIDBServer::PutOrAdd IPC to the network process. writeBlobsToDiskForIndexedDB()
        sends a NetworkProcessConnection::writeBlobsToTemporaryFilesForIndexedDB IPC to the
        network process and the network process will write the blobs to temporary files and
        then return the file paths to those temporary files to the WebProcess. The file paths
        are then stored inside the IDBValue object that gets sent in the WebIDBServer::PutOrAdd
        IPC.

        This patch hardens our IPC by validating in WebIDBServer::PutOrAdd() that the IDBValue's
        Blob file paths were indeed file paths previously created by the network process on behalf
        of the WebProcess sending the IPC. If it is not, we ignore the IPC.

        [WK2] Reduce amount of IPC needed by BroadcastChannel
        https://bugs.webkit.org/show_bug.cgi?id=230181

        Reviewed by Alex Christensen.

        Reduce amount of IPC needed by BroadcastChannel for both registration / unregistration
        and communication. Each WebBroadcastChannelRegistry in the WebProcess now maintains
        a map of BroadcastChannels within the WebProcess. As a result, we are able to dispatch
        messages to other BroadcastChannels within the same process without going via the
        NetworkProcess.

        Also, the NetworkBroadcastChannelRegistry on the NetworkProcess side no longer needs
        to store individual BroadcastChannelIdentifiers. It merely needs to know which
        WebProcesses have one or more BroadcastChannels for a given ClientOrigin / name.
        When NetworkBroadcastChannelRegistry::postMessage() is called, we no longer send
        IPC to the source process in case there are other BroadcastChannels than the source
        with the given ClientOrigin / name in that process. Also, if there is more than
        one BroadcastChannel for the given ClientOrigin / name within a given destination
        WebProcess, we now send a single IPC message instead of sending one per BroadcastChannel.

        This makes it easier to introduce state in WebPage that keeps track of whether or not user action is required
        for showing text editing controls on the touch bar, since we can fetch the (unchanging) state off of

        We also take this opportunity to remove support for the unused _WKSelectionAttributeAtStartOfSentence SPI value
        in _WKSelectionAttributes, which was originally intended for use in Mail compose in WebKit2 but seems to have
        been obviated by the ability to swipe horizontally on the custom input accessory view in Mail compose to switch
        between text candidates and the text formatting options.

        Remove the `atStartOfSentence` bit on EditorState's post-layout data that was only used to implement the
        _WKSelectionAttributeAtStartOfSentence SPI flag value, and also move the `canEnableAutomaticSpellingCorrection`
        bit out of post-layout data, and into the EditorState struct. Importantly, computing this bit does not require
        or trigger layout, and this refactoring will allow us to completely forgo post-layout data on configurations
        that do not require it (i.e. when the text touch bar is not active).

        Reviewed by Wenson Hsieh.

        * mac/postprocess-framework-headers.sh:
        Previously, the framework header postprocessing step operated serially
        on each of our 665 framework headers; not doing a particularly large
        amount of work on any, but still, 20 wall clock ms * 665 headers is
        a good chunk of time.

        Instead, run them in parallel and wait on the result.

        On a 10 core machine, this better than halves the time of a WebKit-only
        null build (from 36 seconds to 15).

        This is definitely not an ideal solution; we're still wasting a ton
        of time launching processes; it's likely possible to get further wins
        here; on the other hand, header postprocessing only takes 2 seconds now.

        Preconnected socket is sometimes not used for initial request
        https://bugs.webkit.org/show_bug.cgi?id=229686

        Reviewed by Alex Christensen.

        In the previous release, we preconnected to the main resource origin early in page load from
        UIProcess to save ~10-15 ms per page load (https://bugs.webkit.org/show_bug.cgi?id=204992).
        The savings comes from the fact that there's some latency in initiating the request in
        WebProcess and waiting for the nav delegate reply in UIProcess. We hide that latency by
        having the eventual main resource request reuse the early preconnected socket.

        However, this optimization doesn't work for connections to known HTTP/1.1 origins due to
        CFNetwork's in-memory cache of known HTTP/1.1 origins. If an origin is in this cache, and
        a preconnect is still in flight, then the network stack will go wide immediately and issue
        the main resource request on a new socket rather than trying to wait for the preconnect to
        finish and reuse the preconnected socket. Thus the preconneted socket just goes to waste.
        This can also cause issues with single-threaded web servers that serve only one request at
        a time, as the main resource request can get head-of-line blocked by the preconnect that
        is wasted.

        To work around this, this patch tracks a small number of known HTTP/1.1 origins in memory.
        If there is a pending preconnect to an HTTP/1.1 origin and a main resource request to that
        origin comes in, then we block the request from going out until the preconnect finishes.
        This allows the main resource request to utilize the preconnected socket.

        This is worth ~1.25%-2.5% on PLT5 depending on device.

        [Mac Catalyst] Korean characters do not combine correctly in editable fields in WKWebView
        https://bugs.webkit.org/show_bug.cgi?id=230122
        rdar://79062204

        Reviewed by Devin Rousso.

        When using Korean input method (e.g. 2-set Korean) to type into editable input fields in WKWebView on Catalyst,
        character combination is broken. While this is partly due to a WebKit-specific UIKit bug (see rdar://82938391),
        this is also broken due to the fact that WKContentView reports a UIWKAutocorrectionContext with a
        `contextBeforeSelection` that starts with a newline (\n); this causes UIKit to believe that the text selection
        range when a single character has been typed is `NSRange { 2, 0 }` instead of `NSRange { 1, 0 }`, due to the
        extra newline. This subsequently causes character combination logic to proceed with a range that is off by one
        character, which leads to characters not being combined (or the wrong characters being combined).

        To address this, we simply avoid including the leading newline in the case where the starting position for the
        "context before selection" is exactly at the first position inside the editable root.

        This adds the infrastructure to use a daemon instead of the network process to handle PrivateClickMeasurement.
        It does not start using the daemon yet, so there is no change in behavior.
        I made a new class PCM::ManagerInterface which can either be a PrivateClickMeasurementManager or a PCM::ManagerProxy,
        which would send messages to the daemon instead of doing the work locally.
        I implemented the encoding and decoding of parameters using some of the IPC encoding templates.
        I have an entry point for an executable but no executable yet.
        I have verified that EventAttribution unit tests pass when using the daemon, so the infrastructure is good.

        Debug build of non-Cocoa ports were broken since r282115 started

        However, MessageArgumentDescriptions.cpp has a long-standing

        [macOS] -[WKFullScreenWindowController exitFullScreenImmediately] does not exit fullscreen immediately
        https://bugs.webkit.org/show_bug.cgi?id=230024

        Reviewed by Jer Noble.

        A WebContent process may ask the `WKFullScreenWindowController` in
        the UI process to exit fullscreen immediately without walking through
        the normal exit fullscreen sequence, and the WebContent process won't
        expect any IPC message related to fullscreen to come back from the
        UI process. If the UI process sends an IPC message to the WebContent
        process and expects the response from the WebContent process (e.g., in
        `WebPageProxy::forceRepaint()`), the UI process will be stuck.

        That will happen when a tab navigates to the previous page while a video
        element in the current page is playing in fullscreen. The reason is that
        `-[WKFullScreenWindowController exitFullScreen]` is called before
        `-[WKFullScreenWindowController exitFullScreenImmediately]`.
        `-[WKFullScreenWindowController exitFullScreen]` changes `_fullScreenState`
        to `WaitingToExitFullScreen`, so `-[WKFullScreenWindowController exitFullScreenImmediately]`
        will return early. This patch fixes this issue by changing the early return condition.

        In addition, `-[WKFullScreenWindowController exitFullScreenImmediately]`
        does not really exit fullscreen immediately. Instead, it calls
        `-[WKFullScreenWindowController finishedExitFullScreenAnimation:]`,
        which always calls `WebPageProxy::forceRepaint()` and expects a response
        from the WebContet process. This patch fixes this issue as well.

        Tested manually.

        * UIProcess/mac/WKFullScreenWindowController.mm:
        (-[WKFullScreenWindowController exitFullScreenImmediately]):
        Update the early return condition to make sure the UI process will proceed
        to exit fullscreen unless the current state is `NotInFullScreen`.
        (-[WKFullScreenWindowController beganExitFullScreenWithInitialFrame:finalFrame:]):
        (-[WKFullScreenWindowController finishedExitFullScreenAnimation:]):
        The `completed` parameter was not used. This patch renames it to `immediately` to
        indicate whether `WKFullScreenWindowController` wants to exit fullscreen immediately.
        (-[WKFullScreenWindowController close]):
        Clean up this function after revising `-[WKFullScreenWindowController exitFullScreenImmediately]`.
        (-[WKFullScreenWindowController windowDidFailToExitFullScreen:]):
        Update the argument according to the change of `-[WKFullScreenWindowController finishedExitFullScreenAnimation:]`.

        argument types right now, and (2) to alleviate the need to add such a
        definition when adding new IPC messages. The string "..." is output
        for types with no operator<< defined.

        The remote and local process IDs are included in the log message. The
        remote process ID is only readily accessible on OS(DARWIN), as we can
        grab it from the XPC connection. But not all IPC::Connections are
        created for XPC connections. For example, the Web -> GPU process
        connection is created by the UI process on behalf of the Web process,
        and the IPC::Connection::Identifier does not have an XPC service
        handle in it. So for now, we omit the remote process ID. (We'd need
        to thread it through messages like CreateGPUConnectionToWebProcess
        to have it available.)

        Since we need the IPC::Connection object for logging now, all of the
        handleMessage* functions take a connection, and the messages.py code
        generator is updated accordingly.

        This is needed to run this code in a process that doesn't have NetworkSession, which is a class tied closely to WKWebsiteDataStore.
        This replaces it with a simple implementation that does the same things:
        1. Uses an ephemeral stateless session that doesn't accept cookies or use credentials.
        2. Does not allow redirects.
        3. Only accepts JSON mime types.
        4. Calls processPCMRequest

        Post-layout `EditorState` updates should be scheduled using `RenderingUpdateScheduler`
        https://bugs.webkit.org/show_bug.cgi?id=229905

        Reviewed by Simon Fraser.

        Use `Page::scheduleRenderingUpdate` rather than `DrawingArea::triggerRenderingUpdate` to ensure that we schedule
        a layer tree flush when sending a full post-layout `EditorState` update to the UI process. On macOS, the latter
        method on DrawingArea will immediately install a runloop observer for the next CA commit, while the former only
        does so after a zero-delay timer fires, courtesy of RenderingUpdateScheduler.

        This prevents us from triggering unnecessary layer tree flushes in the case where the selection changes
        frequently during a single rendering update; in particular, in Speedometer 2 on macOS, this decreases the total
        number of rendering updates performed over the course of the benchmark by roughly 30%.

        NetworkLoadParameters is a heavy object to have on an interface like this.
        We really only need a URL, a RefPtr<JSON::Object> from which the HTTP method can be inferred
        from whether it's null or not, and PcmDataCarried to give to processPCMRequest.

        The NetworkLoadParameters generation is only needed in a networking implementation that uses NetworkSession,
        so I moved it to PrivateClickMeasurementNetworkLoader::start.

        I moved the debugModeEnabled calls to the callers of loadFromNetwork to simplify the interface and to
        keep the responsibility for that in PrivateClickMeasurementManager instead of the loadFromNetwork function,
        which should be simple and just take what it gets and give it to the network.

        No change in behavior.  Just moving things around.

        Buffer large media XHRs in the NetworkProcess to reduce IPC overhead

        Reviewed by Alex Christensen.

        When playing back media through MSE, a significant amount of CPU time is spent sending
        small chunks of loaded media across the XPC boundary, on the order of 16kb at a time out
        of a 1-3MB resource. This large number of small XPC messages, each with a fixed cost, causes
        a relatively large CPU overhead. Media loaded directly through a HTMLMediaElement already
        is coalesced in the NetworkProcess on a 50ms timer.

        Buffer all loads of large media resources, performed over fetch() or XHR, when those resources
        have an expected length of more than 1MB, by coalescing them on the same 50ms timer as we use
        for HTMLMediaElement-generated loads.

        REGRESSION (r280767): Caret color is black after pasting rich text in Mail compose in dark mode

        rdar://82600990

        Reviewed by Tim Horton.

        Partially revert one of the changes in r280767 that makes caret-color follow the immediate container node of the
        selection caret, rather than the focused element (which it previously used). This was effectively a drive-by fix
        for a FIXME about allowing `caret-color` to match child containers inside the root editable container element.
        While this matches behavior on macOS, this change also causes the caret color to become black when pasting rich
        text copied in dark mode, since we write `caret-color: rgb(0, 0, 0);` to the pasteboard when copying the editing
        style for rich text.

        In the short term, we should restore old (pre-r280767) `caret-color` on iOS; in the slightly longer term, I've
        filed bug #229809 to track unifying macOS and iOS caret-color behavior, with respect to nested editable
        container nodes.

        To retain the fix for rdar://81674787 without exhibiting the above bug, we use the selection's root editable
        container (rather than `m_focusedElement`, which was used prior to r280767).

        I am unable to reproduce the crash but we know that we're crashing when committing the load
        after a process-swap, because the WebPageProxy doesn't know that a provisional load is going
        on. One possible explanation for this, and the most likely one is that the WebPageProxy got
        a DidFailProvisionalLoadForFrame IPC from the current process while the provisional load is
        proceeding in the new provisional process. We had logic in WebPageProxy::didFailProvisionalLoadForFrame()
        to try and discard such IPC but the check was relying on the navigationID and was therefore
        fragile. I updated the check in didFailProvisionalLoadForFrame() to ignore all
        DidFailProvisionalLoadForFrame IPCs for the main frame from the current process when there
        is a ProvisionalPageProxy, without relying on the navigationID. This should be more robust
        and will hopefully fix this flaky crash.

        No new tests, unskipped existing tests.

        * WebProcess/GPU/webrtc/LibWebRTCCodecs.cpp:
        (WebKit::LibWebRTCCodecs::encodeFrame):
        - Use adoptCF() to prevent a leak since
          webrtc::createPixelBufferFromFrame() always returns a +1
          retained CVPixelBufferRef now.
        - Change the functor to return a +1 retained CVPixelBufferRef.
        - Reuse `pixelBuffer` to store the converted CVPixelBufferRef
          since this object needs to be kept alive until after the
          send() method is called.

        We should schedule another rendering when the setLayerTreeStateIsFrozen(false) is called.
        In some rare cases, the browser only shows the white page after the page transition,
        because the rendering is skipped while the layer tree is frozen and there was no guarantee that there is

        Make sure window.crossOriginIsolated returns true when COOP=same-origin and
        COEP=require-corp are used. Also make sure that cross-origin-isolates pages
        are allowed to use SharedArrayBuffer.

        When the WebProcess determines it needs to switch browsing context group it
        now sends a NeedsBrowsingContextGroupSwitch::YesWithoutCrossOriginIsolation /
        NeedsBrowsingContextGroupSwitch::YesWithCrossOriginIsolation enum value to
        the UIProcess with the DecidePolicyForResponse IPC instead of a simple
        boolean. We send YesWithoutCrossOriginIsolation when the navigation
        destination will be cross-origin-isolated due to COOP=same-origin and
        COEP=require-corp. In the UIProcess, when YesWithCrossOriginIsolation is
        received, we take care of launching a fresh WebProcess (never recycling an
        existing WebProcess) and we make this WebProcess as cross-origin-isolated.
        When a process is cross-origin-isolated, we pass it a XPC flag on launch
        to allow the process to use SharedArrayBuffer. We use an XPC flag because
        JSC Options need to be set before JSC::initialize() is called, which occurs
        during XPC service initialization. When a WebProcess is marked as
        cross-origin-isolated, we make sure to never cache it so it cannot be
        recycled for a new navigation (given that it has special permission to use
        SharedArrayBuffer).

        In order to do this, I moved common code to DatabaseUtilities and moved the PCM logic from ResourceLoadStatisticsDatabaseStore
        to a new class.  It puts the data in a different file in the same directory unless SPI tells it to put it in a different directory.

        The biggest functional change I needed to do was to make a PCMObservedDomains table in the new DB instead of an ObservedDomains table,
        which contained more information than I needed.  I need just an index and a list of domains.

        Another slight implementation change is that instead of checking isEphemeral in WebResourceLoadStatisticsStore, I just pass an empty
        String to the Store if it's ephemeral, which causes no DB to be created, which causes equivalent behavior.

        I also moved the debug message broadcasting to PrivateClickMeasurementManager::attribute in order to make the Database object not
        need to know about the NetworkProcess and not need to keep state of whether debug mode is enabled.  Database::attributePrivateClickMeasurement
        now returns a DebugInfo object and PrivateClickMeasurementManager::attribute checks whether debug mode is enabled and broadcasts the messages.

        I added a few calls to PrivateClickMeasurement::isolatedCopy when moving an PrivateClickMeasurement object to another thread.

        I added a CompletionHandler to clearPrivateClickMeasurement and clearPrivateClickMeasurementForRegistrableDomain
        so that clearing website data doesn't say it's done until it's done.

        An even smaller change is I added a "ForTesting" suffix on some function names of functions that are only used in tests.

        The rest of this patch just moves code from one location to another.

        I still need to implement migrating data from the old DB to the new DB.  I'll do that in another patch soon.

        [WK2] Reuse the same network load when process-swapping on resource response due to COOP
        https://bugs.webkit.org/show_bug.cgi?id=229465
        <rdar://problem/82307611>

        Reviewed by Alex Christensen.

        r281516 added support for process-swapping based on Cross-Origin-Opener-Policy header
        in HTTP responses. However, on process-swap, we would abort the existing network load
        that was started by the original WebProcess and start a fresh network load in the new
        WebProcess. This was suboptimal and could lead to issues with resources that provide
        one-time behaviors. This patch addresses the issue by transferring the network load
        in the network process from the old WebProcess to the new WebProcess when process
        swapping.

        When the UIProcess decides to process-swap on response policy decision, it first
        sends IPC to the network process to ask it to prepare the NetworkResourceLoader
        for ownership transfer. The network process takes the NetworkResourceLoader
        from its NetworkConnectionToWebProcess and stores it in a temporary cache, then
        responds to the UIProcess with the NetworkResourceLoadIdentifier of the loader.
        Upon receiving the response, the UIProcess proceeds with the process-swap, it
        rejects response processing in the old process and does a loadRequest in a new
        WebProcess. When starting sending the LoadRequest IPC to the new WebProcess, it
        passes along the NetworkResourceLoadIdentifier of the cached loader in the network
        process. When the WebProcess ends up scheduling the load with the network process,
        it passes again the NetworkResourceLoadIdentifier. Upon receiving the load request,
        the network process checks if a NetworkResourceLoadIdentifier is provided for
        continuing a load. If none is provided, we use the regular code path and actually
        construct a new NetworkResourceLoader. However, if a NetworkResourceLoadIdentifier
        is provided, we take the corresponding NetworkResourceLoader from the cache,
        transfer it to the new NetworkConnectionToWebProcess and have it send the
        DidReceiveResponse IPC to the WebProcess to continue the load with the new
        WebProcess.

        Reviewed by Tim Horton.

        Make `transactionID` a monotonic object identifier instead of a generic `TransactionID`, and replace
        `FocusedElementIdentifier` (which is currently type-defined to `uint64_t`) with its own monotonic object
        identifier type.

        In a future patch, I plan to implement a mechanism to synchronize `EditorState` and `FocusedElementInformation`
        updates, which would require one or both of these objects to hold both types of transactional identifiers; in
        order to do this, we need to ensure that these two identifiers are distinct types, so that they can't be easily
        mixed up.

        [iOS] Photo picker appears at incorrect locations when opened using a trackpad

        rdar://80268735

        Reviewed by Wenson Hsieh.

        On iOS, file inputs that accept photos give the user the option to
        select from a photo picker rather than a standard document picker.
        The photo picker is presented as a popover, and uses the content
        view's `lastInteractionLocation` to determine the source rect.
        However, `lastInteractionLocation` is not updated when mouse events
        are recognized, leading to the popover being presented at the location
        of the most recent tap / long press / touch event.

        To fix, ensure `lastInteractionLocation` is updated when a mouse down
        event is recognized.

        "*/*" is a valid MIME type string representing all media types. However,
        the UniformTypeIdentifiers framework (as well as the now deprecated
        CoreServices type identifiers API) does not map wildcard MIME types.

        In order to restrict `UIDocumentPickerViewController` to the types of
        files specified in the accept attribute, all MIME type strings are
        converted into `UTType`s. However, when attempting to retrieve a UTType
        for "*/*", the system dynamically generates a type, since the string is
        unregistered. Then, since no files conform to the dynamic type, all
        files in the document picker are greyed out, and the user is unable
        to access the "Photo Library" and "Take Photo or Video" items.

        To fix, return an empty set of type identifiers whenever "*/*" is
        present in the list of MIME types, ensuring there are no restrictions
        on the types of files that can be selected.

        Note that the same issue does not occur on macOS, since all MIME types
        are mapped to a set of file extensions, rather than UTTypes. Furthermore,
        on macOS, the embedding app, not WebKit, is responsible for displaying
        the file picker.

        Remove some iOS-specific compile-time guards that are no longer needed
        https://bugs.webkit.org/show_bug.cgi?id=229500

        Reviewed by Tim Horton.

        Remove two compile-time flags that were no longer necessary after WebKit's minimum supported iOS version became
        iOS 14: `USE(UIKIT_KEYBOARD_ADDITIONS)` and `HAVE(NONDESTRUCTIVE_IMAGE_PASTE_SUPPORT_QUERY)`.

        `HAVE(NONDESTRUCTIVE_IMAGE_PASTE_SUPPORT_QUERY)` was only needed for a workaround in our test infrastructure,
        while `USE(UIKIT_KEYBOARD_ADDITIONS)` was only introduced to maintain basic hardware keyboard functionality in
        iOS 12, while supporting improvements to hardware keyboard support in iOS 13.

        The latter now only guards `PLATFORM(IOS) || PLATFORM(MACCATALYST)`. However, there's no reason the codepaths
        for hardware keyboard support can't exist on watchOS as well (especially since most of hardware keyboard
        support is already implemented there -- just unreachable because it's not possible to attach a hardware keyboard
        to an Apple watch). We can remove this feature flag, and simply delete code that was formerly guarded by
        `!USE(UIKIT_KEYBOARD_ADDITIONS)`.

        UIKit throws an exception when attempting to present a context menu
        for a view that is not in a window.

        One instance where this can occur in Safari is when a call to
        window.open() is made in response to a touch on a select element.
        In this scenario, the call to window.open() opens a new tab, unparenting
        the current webview. However, the touch also focuses the element, and
        WebKit attempts to present a context menu in an unparented view.

        To fix, guard against the case where the view is not parented, and do
        not attempt to present a context menu.

        [WK2] Implement process-swapping based on Cross-Origin-Opener-Policy HTTP header
        https://bugs.webkit.org/show_bug.cgi?id=229203
        <rdar://problem/82047686>

        Reviewed by Alex Christensen.

        We recently added support for the Cross-Origin-Opener-Policy (COOP) HTTP header. However,
        when switching browsing context group on HTTP response, we would keep using the same 
        WebProcess. This patch makes it so that we now swap WebProcess when switching browsing
        context group on network response as this will be required to securely re-enable Web APIs
        such as SharedArrayBuffer.

        For process-swapping, we reuse most of the same logic as process-swap on navigation (PSON).
        A few differences are that:
        - We swap on response policy decision instead of navigation policy decision
        - We used to have a ShouldTreatAsContinuingLoad Yes/No enum. It is now tri-state: No,
          YesAfterNavigationPolicyDecision, YesAfterResponsePolicyDecision. We need this new state
          to avoid duplicate response policy delegate calls after process-swapping and to avoid
          sending duplicate didStartProvisionalLoad IPCs after proces-swapping.
        - After process-swapping on navigation response, we close the previous page instead of trying
          to put it into the back/forward cache. Per the specification, in a case of a browsing context
          group switch, the previous browsing context needs to be discarded (which is Web-observable).

        One important thing to note is that we currently send the HTTP request to the server AGAIN after
        a process-swap. This is because the on-going load currently gets cancelled upon receiving the
        network response and deciding to process-swap and a new fresh load gets issued by the new
        WebProcess after swapping. I will address this in a follow-up to decrease patch size and
        complexity. We will need to transition the load in the network process from the old WebProcess
        to the new one in case of process-swap.

        REGRESSION (r271146): editing/selection/ios/scrolling-to-focused-element-inside-iframe.html is failing
        https://bugs.webkit.org/show_bug.cgi?id=229376
        rdar://80384683

        Reviewed by Megan Gardner.

        This iOS-specific test verifies that tapping on an element that makes itself contenteditable inside of a click
        event handler both (1) brings up the software keyboard, and (2) scrolls to reveal the focused, newly editable
        element such that it is not obscured by the software keyboard. This test began failing after the changes in
        r271146 -- specifically, the fact that the call to `Element::setFocus()` moved to before the focus event is
        dispatched, rather than afterwards.

        The following timeline of events (annotated with web and UI processes) illustrates why this happens:

        (WEB)   1.  The click event on the element inside the subframe is handled; the element is made contentEditable,
                    and we make it focused, by first calling `Element::setFocus` and then `Element::dispatchFocusEvent`.
                    Right before dispatching the "focus" event, we call out to the client layer, via
                    `WebPage::elementDidFocus`, and compute a FocusedElementInformation struct to encode and send to the
                    UI process in the WebPageProxy::ElementDidFocus IPC message.

                2.  In the process of populating this struct in `WebPage::focusedElementInformation`, we observe that
                    layout is dirty, and immediately compute and send an EditorState underneath
                    `WebPage::sendEditorStateUpdate()`.

                3.  We then proceed to construct and send FocusedElementInformation to the UI process via
                    `Messages::WebPageProxy::ElementDidFocus`.

        (UI)    4.  We receive the EditorState that was computed and sent in step (2), which contains the up-to-date
                    state corresponding to the newly focused contentEditable `div`.

                5.  We then receive the FocusedElementInformation computed and sent in step (3), which makes us begin
                    waiting for the next post-layout EditorState update before zooming to reveal the focused element, by
                    setting WebPageProxy's `m_waitingForPostLayoutEditorStateUpdateAfterFocusingElement` flag. However,
                    this post-layout EditorState after focusing the `div` never arrives, since we've already computed it
                    and sent it in step (2).

                6.  The software keyboard finishes animating in, causing us to resolve the UIScriptController promise
                    that we began to await after calling `UIHelper.activateAndWaitForInputSessionAt` in the test.

        (WEB)   7.  The test finishes, calls `testRunner.notifyDone()`, and we destroy the focused subframe and clear
                    the editable selection as well. This selection change causes us to compute another post-layout
                    editor state and send it to the UI process.

        (UI)    8.  The UI process *finally* receives the post-layout EditorState computed in (7). However, it's too
                    late, since (a) the test has already finished, and (b) the post-layout EditorState is computed after
                    the editable selection has already been cleared, so it's missing selection rect information anyways.

        Prior to r271146, the call to `Element::setFocus` came *after* step (3), and caused us to compute and send
        another EditorState to the UI process, which ensured that an up-to-date post layout EditorState would arrive in
        the UI process shortly after step (5).

        To fix this, we should avoid immediately computing and sending an EditorState to the UI process in the middle of
        `WebPage::focusedElementInformation`, and instead simply schedule an EditorState during the next rendering
        update. This ensures that the editor state triggered during element focus will always arrive after
        `WebPageProxy::ElementDidFocus` in the UI process, rather than before, which allows us to scroll to the correct
        selection rect in the UI process when focusing an editable element.

        This also has the additional benefit of avoiding redundant EditorState computation and updates in the case where
        focus is programmatically thrashed between elements during the same rendering update, since all of the editor
        state updates are effectively batched together and dispatched at the end of the current rendering update.

        WebKit2 can only have one active navigation policy check for a given frame

        Reviewed by Youenn Fablet.

        WebKit2 could only have one active navigation policy check for a given frame

        several navigations (e.g. in new windows) and only the last one would proceed
        (earlier ones would get cancelled).

        This patch updates the policy checking logic in WebFrame so that we can support

        [iOS] Fix and reenable several layout tests to account for the changes in rdar://80384564
        https://bugs.webkit.org/show_bug.cgi?id=229316

        Reviewed by Tim Horton.

        After rdar://80384564, UIKit's non-editable text tap recognizer will no longer cause us to clear the active text
        selection range when tapping outside of currently selected text in the page. Instead, WebKit's synthetic click
        gesture recognizer should now manages clearing the selection (unless the page has prevented the "mousedown"
        event).

        With just the UIKit-side change, this already mostly works as expected since `commitPotentialTapFailed()` clears
        out non-editable selections. However, there is one scenario in which we do want to clear out the selection when
        tapping that isn't covered by the synthetic click gesture: when tapping on an element that does not handle or
        prevent "mousedown"; this behavior is exercised by the existing layout test
        `editing/selection/ios/hide-selection-after-tap-on-prevent-default-element.html`. To preserve this behavior, we
        add a call to `clearSelectionAfterTapIfNeeded()` when completing a synthetic click, in the case where the
        "mousedown" event was not swallowed.

        These 3 tests should pass after the changes in rdar://80384564:
        - editing/selection/ios/change-selection-by-tapping-with-existing-selection.html
        - editing/selection/preserve-selection-when-clicking-button.html
        - editing/selection/ios/persist-selection-after-tapping-on-element-with-mousedown-handler.html

        And these WebKit-side changes are needed to keep these 2 tests passing:

        - fast/images/text-recognition/ios/reselect-word-in-image-overlay.html

        [iOS] Remove support for the meaningful tap heuristic

        rdar://82130066

        Reviewed by Tim Horton.

        Remove all support for the meaningful tap heuristic, which was used to allow users to toggle tab pill visibility
        in earlier versions of the Safari redesign. As of the latest iOS 15 beta, this heuristic is no longer necessary,
        so we don't need this SPI support anymore.

        Replace the uint64_t used to identify taps with an ObjectIdentifier<> type
        https://bugs.webkit.org/show_bug.cgi?id=229278

        Reviewed by Wenson Hsieh.

        Interaction code used "uint64_t requestID" to identify taps, but there are other
        things that used "uint64_t requestID", which may result in bugs.

        Fix by using a strongly typed ObjectIdentifier<TapIdentifierType> to identify taps.
        This is defined in IdentifierTypes.h since I expect to add more of them.

        Adjust fallback SandboxExtension std::optional<Handle> construction

        Reviewed by Carlos Garcia Campos.

        In r240512, std::optional<> was adopted as the return type for handle
        creation methods in the SandboxExtension class. For no-op methods,
        the construction of these return values was done using empty initializer
        lists.

        The changes here should match pre-r240512 behavior by creating empty
        Handle objects and using those to implicitly construct the returning
        std::optional<> object. In addition, this avoids compilation breakage
        with GCC 8 where ambiguity between possible std::optional<> constructors
        is detected.

        REGRESSION (iOS 15): DoubleDown Casino app won't load past launch page
        https://bugs.webkit.org/show_bug.cgi?id=229200
        rdar://81636256

        Reviewed by Myles C. Maxfield.

        The changes in https://webkit.org/b/228216 to fix rdar://80473805 introduced a mechanism to keep track of uses
        of cached fonts and images in display list items in the web and GPU processes, via a `useCount` counter variable
        that's incremented in the web process whenever the font or image is used in a display list item and decremented
        in the GPU process whenever the item is processed.

        However, the code to increment `useCount` in the web process currently only triggers at most once per rendering
        update — this means that if there are multiple canvas drawing commands that use fonts in the same rendering
        update, the web process' notion of `useCount` will fall out of sync with the GPU process' notion of `useCount`.

        In most cases, this causes the cached font to remain for longer in the GPU process than necessary; however, in
        this specific scenario, it's possible for the web process to tell the GPU process to release the cached font too
        early, which causes the GPU process to prematurely purge the font from the cache, and subsequently wait for the
        cached font to arrive (which will never arrive, since the web process has already released the font).

        In other words, the timeline of events between the web and GPU processes looks like this (where `f` is a cached
        web font, `A_f` is a drawing command that uses `f`, and `B_f` is another drawing command that uses `f`).

        WEB                                             GPU
        ==============================================================
        1. Cache `f`
        2. Append `A_f`
                                                        3. Cache `f`
                                                        4. Play back `A_f`
        5. Append `B_f`
        6. Release `f` (use count was 1 here)
                                                        7. Release `f` (use count dropped from 1 to 0)
                                                        8. Play back `B_f`
                                                        ...and then display list playback stops due to `f` not being in
                                                        the cache.

        To address this, we simply move the `useCount` increment in the web process out of the rendering update check.
        The original intent of the fix for bug #228216 was to allow for `useCount` to increment as many times as needed
        per rendering update, so this limitation was unintentional.

        Unfortunately, I have not been able to come up with a layout test that reliably reproduces this scenario (yet).

        rdar://80386326

        Reviewed by Tim Horton.

        This test crashes when run immediately after another test that attempts to present the context menu and ends
        with the context menu still showing (in this case, fast/events/touch/ios/long-press-on-image.html). Running
        these tests back to back causes us to immediately dismiss the context menu interaction while transitioning to
        the second test, which triggers the context menu interaction's dismissal animation.

        This animation ends in the middle of the next test (long-press-on-link.html), after the long press has begun and
        the context menu interaction has already requested a targeted hint preview, but (importantly) before the context
        menu peek animation actually begins (i.e. `-contextMenuInteraction:willDisplayMenuForConfiguration:animator:`).
        As a result, we tear down the hint container too early (with the hint view still in the view hierarchy), and
        subsequently crash with an exception when UIKit tries to perform coordinate space conversions with the now-
        unparented view.

        To fix this, we make two small adjustments:
        1.      Avoid unparenting the context menu hint container if it still has subviews.
        2.      Add plumbing to ensure that the context menu hint container is unparented once all of its subviews have
                been removed (and the container isn't being used for anything else).

        Terminating the GPUProcess is very stressful situation which has to be
        handled carefully. The side effect of each function which is called through
        gpuProcessConnectionDidClose() has to be understood to get the right
        sequence of calls. There are problems in releasing all kinds of resources.

        - Releasing NativeImage: Calling clearNativeImageMap() after clearing the
        backend of the ImageBuffers was causing a problem. When clearing the
        backend of an ImageBuffer, it will clear its DisplayList which may have
        the last reference to a NativeImage. The destructor of NativeImage calls
        releaseRemoteResource() before it is removed from the the NativeImageMap.
        This will send a message to the relaunched GPUP to release a NativeImage
        which is not in its cache.

        - Releasing Font: clearFontMap() was always calling releaseRemoteResource()
        even if it is called form  remoteResourceCacheWasDestroyed(). This should
        not happen because the connection with GPUProcess has been closed.

        - Releasing ImageBuffer: This happen when a DisplayList of an ImageBuffer
        'A' holds the last reference to another ImageBuffer 'B' and we call
        clearBackend() for 'A'. clearBackend() will clear the DisplayList of 'A'
        and causes the deletion of 'B'. In this case we should not call 
        releaseImageBuffer() for 'B' because the GPUPProcess is closed.

        * WebProcess/GPU/graphics/RemoteImageBufferProxy.h:
        (WebKit::RemoteImageBufferProxy::~RemoteImageBufferProxy):
        If the ImageBuffer is being released because of the clean-up we do when
        the GPUProcess is terminated, we should not release the corresponding 
        RemoteImageBuffer since it is already gone.

        * WebProcess/GPU/graphics/RemoteRenderingBackendProxy.h:
        (WebKit::RemoteRenderingBackendProxy::isGPUProcessConnectionClosed const):
        This will return true if we are deleting a RemoteImageBufferProxy through
        RemoteResourceCacheProxy::remoteResourceCacheWasDestroyed().

        * WebProcess/GPU/graphics/RemoteResourceCacheProxy.cpp:
        (WebKit::RemoteResourceCacheProxy::releaseAllRemoteFonts):
        This function will be used to release the remote fonts. It should be called
        from RemoteResourceCacheProxy::releaseMemory() where we sure the GPUP is
        alive and all the fonts are cached there.

        (WebKit::RemoteResourceCacheProxy::clearFontMap):
        The part of releasing the remote fonts was moved from this function to 
        releaseAllRemoteFonts().

        (WebKit::RemoteResourceCacheProxy::remoteResourceCacheWasDestroyed):
        1. Clearing the NativeImages and the Fonts has to come before clearing
        the backends of the ImageBuffers. The reason is clearBackend() clears the 
        DisplayList which may release the last reference of a NativeImage or Font.
        We want to detach the NativeImages and the Fonts from the cache before then.
        2. We should have two different loops: one for clearing the backends of
        the ImageBuffers and another one for recreating these backends. The reason
        for this is clearBackend() clears the DisplayList which may release the
        last reference of a another source RemoteImageBufferProxy used by a 
        DrawImageBuffer item for example.

        After the GPU process crashes, the UI process will clean up the

        the media playback and setup `AudioSessionRoutingArbitrator`.
        There is a race condition here. If the WebContent process runs faster,

        Suspend WorkQueue of ResourceLoadStatistics and LocalStorage sooner

        When suspending ResourceLoadStatistics and LocalStorage, we dispatched a suspend task, which waits on a 
        condition, to their WorkQueue. That means the queue will be suspended after completing all tasks scheduled 
        before the suspend task. These tasks may take a long time to complete and assertion may be timed out.

        When network process receives PrepareToSuspend message, we want the queues to suspend as soon as possible. To 
        achieve that, now we check if the queue needs to be suspended before each task, which ensures the queue 
        execute as most one task after suspend().

        [Cocoa|GPU] platformLayer() not always added to remotedly hosted context; black video while playing

        <rdar://81271107>

        Reviewed by Eric Carlson.

        Currently, the RemoteMediaPlayerProxy will insert its MediaPlayer's platformLayer() into the
        remotely hosted context when it receives a "firstVideoFrameAvailable()" notification.
        However this is problematic for two reasons: AVPlayerLayer may not become "ready for
        playback" when it is not in an active CALayer heirarchy, and for
        MediaPlayerPrivateAVFoundation, firstVideoFrameAvailable() is only fired during
        updateStates(), which is not guaranteed to occur unless another state change occurs.

        Instead, reparent the MediaPlayer's platformLayer() when we receive a
        mediaPlayerRenderingModeChanged() notification, which notifies the client whenever a
        platformLayer() is created or destroyed.

        Address an existing FIXME which (mostly) fixes this bug. Currently, the caret color is only computed when
        `WebPage::m_focusedElement` is set. However, when resigning first responder, we clear out `WebPage`'s
        `m_focusedElement`) right before updating the DOM selection, which creates a brief window during which we
        compute an `EditorState` with a `caretColor` of transparent black.

        To avoid this inconsistency, we instead compute the caret color from the selection container; this has the
        additional benefit of allowing the caret color to change when changing selection within a single editable host
        with multiple caret colors (instead of always just using the focused element's caret color).

        Note that while this adjustment to `WebPage::getPlatformEditorState` is sufficient to ensure that the value of
        `-[WKContentView insertionPointColor]` (which is based on `EditorState`) is always up-to-date, this doesn't
        guarantee that the actual color of UIKit's caret view reflects the updated `-insertionPointColor`, which results
        in situations where the caret color appears out-of-date after hiding the keyboard and refocusing an input field.
        To fix this, we need the other adjustment in WKContentView (see above).

        [macOS] 3 second IPC deadlocks involving WebPageProxy::acceptsFirstMouse
        https://bugs.webkit.org/show_bug.cgi?id=228834
        rdar://75390908

        Reviewed by Wenson Hsieh and Tim Horton.

        Reports show 3 second hangs in WebPageProxy::acceptsFirstMouse, which is
        the timeout for the sync IPC sent by the method. While this method has
        always sent a sync IPC, logs show the WebProcess is also blocked on sync
        IPC, under WebProcess::ensureGPUProcessConnection.

        If a Web<->GPU process connection has not been established,
        WebProcess::ensureGPUProcessConnection sends a sync IPC from the
        WebProcess to the UIProcess to establish get the connection. However, to
        get the connection, the UIProcess then sends an async IPC with a reply
        block to the GPUProcess (see GPUProcessProxy::getGPUProcessConnection).
        The WebProcess remains blocked until the UIProcess receives the reply
        from the GPUProcess, and then sends a reply to the WebProcess.

        Now, if a call to acceptsFirstMouse occurs in between the time the async
        UIProcess -> GPUProcess IPC is sent, and the reply is received, we will
        experience deadlock. The UIProcess will be blocked waiting on the
        WebProcess' reply to acceptsFirstMouse, and the reply from the GPUProcess
        will not be dispatched. Since the reply from the GPUProcess will not be
        dispatched until the UIProcess is unblocked, the WebProcess will be
        waiting under WebProcess:ensureGPUProcessConnection, and unable to reply
        to acceptsFirstMouse.

        A simple fix for the described scenario would be to introduce a
        replySendOptions parameter to sendWithAsyncReply, so that the UIProcess
        could be re-entered to dispatch the GPUProcess reply, even when waiting
        for acceptsFirstMouse. However, this will not work in cases where the
        GPUProcess is being launched, due to being blocked on the reply from
        xpc_connection_send_message_with_reply in ProcessLauncherMac, which is
        before the IPC::Connection has been established.

        Since re-entering the UIProcess is not possible in this scenario, given
        the existing architecture, the next simplest solution is to re-enter
        the WebProcess on acceptsFirstMouse instead. Consequently, one part of
        the fix involves sending the acceptsFirstMouse IPC with
        IPC::SendOption::DispatchMessageEvenWhenWaitingForUnboundedSyncReply and
        tagging WebProcess::getGPUProcessConnection as unbounded sync IPC.

        Then, we must also consider the fact that, in the WebProcess,
        acceptsFirstMouse performs hit-testing. Hit-testing triggers layout and
        could cause script to run. Script could result in a GPUProcess connection
        being established, eventually leading us down the path towards the
        aforementioned deadlock. To avoid deadlock in this scenario, we need to
        interrupt acceptsFirstMouse if a message to get the GPUProcess connection
        is received. This is achieved by using waitForAndDispatchImmediately with
        the InterruptWaitingIfSyncMessageArrives option, and splitting up
        acceptsFirstMouse into two separate IPCs.

        (essentially making it a sync IPC), so that the wait can be interrupted

        On iOS devices that support both 3D Touch and Visual Look Up (i.e., iPhone XS and iPhone XS Max), it's currently
        possible to skip the image analysis preflight gesture entirely when showing the context menu over images in the
        case where the user triggers the interaction by exceeding the force press threshold in under 100 ms (the current
        delay of the image analysis long press gesture).

        Mitigate this by teaching WKImageAnalysisGestureRecognizer to trigger image analysis preflight slightly ahead of
        the context menu interaction when performing a force press by transitioning to Began state early under
        `-touchesBegan:withEvent:` and `-touchesMoved:withEvent:`, if the touch's force exceeds a certain (relatively

        Reviewed by Andy Estes.

        r275169 made it so that `paymentMethodType` is no longer `required` so that `additionalShippingMethods`
        can be specified without having to limit it to a specific payment method type. While this
        works in theory, WebKit doesn't know about the user's selected payment method type until the
        user actually selects a payment method, meaning that until then the `additionalShippingMethods`
        are not used. Unfortunately (until now) `PKPaymentRequestPaymentMethodUpdate` did not
        support providing a `NSArray<PKShippingMethod *> *`, so there was no way to update the list
        of shipping methods when the user changed their selected payment method, meaning that WebKit
        would have to wait/rely on the user to change their shipping address _after_ selecting a
        payment method in order for `additionalShippingMethods` to take effect.

        This also fixes an issue with WebKit's implementation of the W3C Payment Request API by
        allowing any generic (i.e. things not specific to Apple Pay) `shippingOptions` provided in
        `PaymentDetailsUpdate` to actually be used and update the Apple Pay sheet accordingly.

        [iOS] <select> picker value committed to incorrect element after programmatic focus change
        https://bugs.webkit.org/show_bug.cgi?id=228556
        rdar://81222952

        Reviewed by Wenson Hsieh.

        The old <select> picker is a UIPickerView that only commits any value
        changes to the WebProcess once the user dismisses the picker, or focus
        is lost programmatically. Currently, the value change is committed by
        sending a message to the WebProcess, telling it to update the value of
        the currently focused element. However, when focus is changed
        programmatically, the focused element in the WebProcess is updated
        before the commit, and the incorrect element's value can be changed.

        To fix, update all methods which commit value changes to the focused
        element to take an ElementContext parameter representing the element
        that needs its value modified. Then, in the WebProcess, rather than
        commit the value change to the currently focused element, retrieve the
        element from the ElementContext, ensuring the correct element is
        updated.

        Note that this bug only surfaces in the old <select> picker, on apps
        linked before iOS 13, since the new picker commits value changes

        [iOS] REGRESSION: Tapping a <select> element does not show a menu on many websites
        https://bugs.webkit.org/show_bug.cgi?id=228340
        rdar://77137768

        Reviewed by Wenson Hsieh.

        Many sites add a touchend event listener to their select elements, that
        is responsible for focusing the element. With the introduction of
        asynchronous touch events, the single tap gesture recognizer can be
        deferred to the point it occurs after the UIProcess is notified that an
        element has been focused. This is problematic, since the UIProcess
        creates and displays inputs peripherals in response to element focus,
        but the gesture recognizer can dismiss presented peripherals via
        `-[WKFormPeripheral endEditing]`. Consequently, many sites immediately
        display and dismiss the input peripheral.

        To fix, only call `-[WKFormPeripheral endEditing]` if the peripheral
        was already being displayed once the tap gesture began. This ensures we
        do not immediately display and dismiss peripherals.

        Note that with the redesigned form controls, the call to `endEditing` is
        unnecessary, as the presented views handle their own dismissal. However,
        the logic is still needed for the old select control (using a keyboard
        input view), to commit value changes. The old control is displayed on
        apps linked against iOS 13 or earlier. This behavior is tested in
        fast/forms/ios/select-picker-change-and-focus-another-select.html.

        Safari hangs when entering PiP from (element) fullscreen
        https://bugs.webkit.org/show_bug.cgi?id=228332

        Reviewed by Eric Carlson.

        When a video element's ancestor element is in fullscreen and the video element
        is entering picture-in-picture, `WKFullScreenWindowController` in the UI process
        will notify the WebContent process that the ancestor element needs to exit fullscreen.
        However, some sites call `document.webkitExitFullscreen()` to request the ancestor
        element to exit fullscreen proactively. Both WebContent process and UI process will
        try to do the same thing and may lead to a race condition.

        That was not an issue before r274460 because `WebFullScreenManager::requestExitFullScreen()`
        will ignore the request from the UI process if the WebContent process has already
        started the steps to exit fullscreen.

        This patch stops the UI process sending the exit fullscreen request if a WebContent
        process has started the steps to exit fullscreen.

        [macOS Monterey] Pressing Fn+E should present the emoji picker when editing
        https://bugs.webkit.org/show_bug.cgi?id=228300
        rdar://77558672

        Reviewed by Tim Horton.

        In macOS Monterey, the system-wide Fn+E key command presents the Emoji & Symbols UI as a popover. However, this
        new key command currently does not work in editable contexts in both WebKit1 and WebKit2 views on macOS, where
        we end up just inserting the character "e".

        This is because, on both ports, we attempt to interpret NSEvents by calling back into AppKit to handle the
        event, recording the selectors that *would've* been performed, and then using this information to build up a
        list of WebCore::KeyCommand for the event (which are later converted into editing commands). In WebKit2, we
        call into `-[NSTextInputContext handleEventByKeyboardLayout:]` to handle the event, and capture the resulting
        calls back into `WKWebView` by storing entries in `m_collectedKeypressCommands` (something similar happens in
        WebKit1). In the case of these new Fn commands, they are handled by the system before entering
        NSTextInputContext, so NSTextInputContext ends up handling them as regular text insertion.

        As an aside, the reason the meta (⌘) key doesn't encounter this problem is because meta, option, control and
        shift are considered valid key bindings in NSKeyBindingManager, whereas the function key mask is specifically
        excluded from this list for compability reasons. NSTextInputContext consults NSKeyBindingManager in order to
        check whether the given NSEvent is a known key binding in `-handleEventByKeyboardLayout:`, so it fails to
        acknowledge Fn+E as a key binding.

        To work around this, we adopt new AppKit SPI added in rdar://81123724 to determine whether an NSEvent maps to
        any main menu items and avoid handling "Fn-*" key events as text insertion if they already map to items in the
        main menu.

        [GPU Process] Add resource use counter infrastructure to RemoteResourceCache
        https://bugs.webkit.org/show_bug.cgi?id=228222

        Reviewed by Said Abou-Hallawa.

        This patch adds the infrastructure for associating a counter with each resource in the RemoteResourceCache.
        As the web process uses a resource during display list recording, it increments a counter, and as the GPU
        process uses a resource, it increments a counter in the RemoteResourceCache. When the web process is done
        with a resource, it sends a release message to the GPU process which crucially includes the web process's
        counter. The GPU process has to then wait to actually delete the resource until its own use counter matches
        the one it received from the web process. This patch implements this deferred deletion infrastructure
        in the GPU process.

        [iOS] Unified field is unselected after focusing URL bar if text was selected in a fixed position container

        rdar://80556392

        Reviewed by Tim Horton.

        In Safari on iOS 15, if the selection (either ranged or caret) is inside a fixed position container when the
        user taps on the unified field, we'll immediately clear the text selection inside the unified field upon
        bringing up the keyboard. This happens because the tab pill in iOS 15 is lowered as the URL bar is focused,
        which causes the web view to scroll slightly. This, in turn, induces a brief unstable scrolling tree state,
        which then causes us to temporarily hide and show selection views while scrolling in unstable state (see
        r209931) by calling `-deactivateSelection` and then `-activateSelection` on the text interaction assistant.
        Calling `-[UIWKTextInteractionAssistant activateSelection]` then causes UIKit to dispatch a
        UITextSelectionViewActivatedNotification; In the unified field, which is a UITextField subclass, UIKit code then
        listens for this notification and responds to it by clearing the selection if the newly activated selection's
        host view (WKContentView) is different than itself, thereby causing the bug.

        To fix this, we simply make two (minor) adjustments to the logic for temporarily hiding and showing the
        selection while performing an unstable scroll. See below for more details.

        (-[WKContentView _updateChangedSelection:]):

        Only attempt to show the selection views again if doing so doesn't cause us to steal first responder status away

        After r279751, the snapshot fallback codepath I added in `createShareableBitmap` to handle the edge case of
        fully transparent images causes us to now take snapshots when hovering over fully transparent video elements,
        and attempt to recognize text in them. This is because RenderVideo is a RenderImage subclass without a cached
        image, so we'll end up going down the transparent renderer codepath instead of bailing with a null bitmap.

        However, since CachedImages are null for video elements, before we even get to VisionKit, we end up crashing
        with a nullptr-deref inside `WebPage::requestTextRecognition`, which assumes that `RenderImage::cachedImage()`
        is non-null.

        To address this, we make two minor adjustments (see below).

        for keychain AutoFill suggestions), but only the latter additionally supports contact AutoFill suggestions.

        As such, we should change these to use WKTextInputListViewController instead of PUICQuickboardController. Note
        that because contact AutoFill suggestions do not encompass passwords, it still makes more sense to pop directly

        [GPU Process] Migrate the DisplayList::Replayer::Delegate from RemoteImageBuffer to RemoteRenderingBackend
        https://bugs.webkit.org/show_bug.cgi?id=228219

        Reviewed by Wenson Hsieh.

        This is part 1 of https://bugs.webkit.org/show_bug.cgi?id=228216.

        For this task, we need to count resource uses:
        1. As the recorder in the web process records DisplayList items which reference resources, those uses need to increment a counter.
        2. As the replayer in the GPU process replays DisplayList items which reference resources, those uses need to increment a parallel counter.

        The most natural place for the counters to live is in RemoteResourceCacheProxy and RemoteResourceCache, respectively. These two classes
        are accessible from the RemoteRenderingBackendProxy and RemoteRenderingBackend, respectively. The most natural interface between the
        DisplayList classes like DisplayList::Recorder and DisplayList::Replayer and the higher level WebKit classes is to use their delegate
        interfaces.

        For 1 above, RemoteImageBufferProxy has access to the RemoteRenderingBackendProxy and is already a DisplayList::Recorder::Delegate, so
        there's no problem there. However, for 2, messages are delivered first to the RemoteRenderingBackend, which is the place that has access to
        the RemoteResourceCache. Making the RemoteRenderingBackend have the DisplayList::Replayer::Delegate would be a natural place to either
        A) call the necessary function in the RemoteImageBuffer, or B) interact with the RemoteResourceCache to increment the necessary counter.

        Indeed, this makes a lot of sense because, for 2 of the 3 delegate methods, RemoteImageBuffer just immediately turns around and forwards
        the call to the RemoteRenderingBackend anyway. So, migrating this interface to RemoteRenderingBackend actually ends up making it a bit
        simpler.

        No new tests because there is no behavior change.

        (WebKit::RemoteLayerBackingStore::applyBackingStoreToLayer):
        r279992 reorganized this code to determine the contents object and then
        set it on the layer, instead of setting it directly; this means that the
        lifetime of the contents object must be extended.

        Interestingly, the common case (the CAMachPort case), as well as the
        case I was actually adding in r279992 both were safe, because of the use
        of autorelease. (macCatalyst uses IOSurface as layer contents directly,
        without CAMachPort, so uses the one path that r279992 broke).

        It is unnecessary to use autorelease; instead just store the contents
        object in a RetainPtr until it is set.

        Avoid Quick Note overlay when scrolling to show a highlight

        Reviewed by Wenson Hsieh and Tim Horton.

        When scrolling to show the selected highlight after clicking on one in the QuickNote overlay,
        make sure to avoid the Quick Note overlay, so that the user can actually see the highlight. 
        This required calculating more information about the selection rect for iOS, and also piping through
        information to have the selection rect be the entire rect, rather that just the caret and the end of selection.

        Because it is hard to keep track of whether or not a transaction has already been started in
        ResourceLoadStatisticsDatabaseStore code and because passing a transaction as parameter adds
        a lot of function overloads, I decided to switch to another approach. I added a
        beginTransactionIfNecessary() member function that begins a transaction if there isn't one
        already going on. This way, we can safely ask to begin a transaction within the scope of
        a function (if we're about to do several write statements), without having to worry about
        whether or not our caller already started a transaction.

        Reviewed by Chris Dumez.

        r279006 made it so that taking empty snapshots would no longer crash due
        to division by zero, or assertions on the size of the returned image.

        However, the change introduced a new crash, as a result of a deallocated
        completionHandler. r279006 move-captured the completion handler. However,
        since completionHandler is an Objective-C block, and WebKit is built
        without ARC, the move does not retain the block. Consequently, the
        method can call a deallocated completion handler.

        To fix, capture the local handler variable already available in the
        method, which retains the completion handler using makeBlockPtr.

        Rename the SPI added in r280119 from `-_needsSiteSpecificQuirks` to `-_needsSiteSpecificViewportQuirks`, to
        clarify its intent (and importantly, to differentiate it from the existing WKPreferences SPI of the same name).

        This distinction is important because this readonly property acts as a hint for WebKit clients to augment
        certain viewport behaviors, whereas the readwrite WKPreferences property is a way for clients to indicate that
        WebKit should opt in or out of site-specific quirks (unless overridden by Web Inspector).

        IBeam cursor is horizontal in Mail compose window

        Recently we added support for vertical writing mode for the IBeam
        cursor in WebKit. This added a new parameter isHorizontalWritingMode
        which defaults to false. This causes the IBeam to appear horizontal in
        cases where WebPage::populateCaretContext is not called, regressing expected
        behavior. 

        This patch changes isHorizontalWritingMode to isVerticalWritingMode
        to fix this, while still allowing support for vertical writing mode.

        [GTK] Propagate GtkSettings to web process
        https://bugs.webkit.org/show_bug.cgi?id=227854

        Reviewed by Carlos Garcia Campos.

        There's a number of properties in GtkSettings that web process uses:

        - gtk-cursor-blink
        - gtk-cursor-blink-time
        - gtk-font-name
        - gtk-primary-button-warps-slider
        - gtk-theme-name
        - gtk-xft-antialias

        - gtk-xft-hinting
        - gtk-xft-hintstyle
        - gtk-xft-rgba

        While we do propagate gtk-theme-name, we don't do it for any of the other settings.
        This means that they can only be fetched from XSettings/GSettings/settings portal
        by GTK itself, but if the app changes them or if they are changed from inspector,
        web processes won't see that.

        Introduce GtkSettingsManager as a specific place that listens to preferences
        changes and notifies the web process, where GtkSettingsManagerProxy updates
        GtkSettings on that side. Keep the dark mode preference separate since there's
        existing cross-platform infrastructure for it.

        Apply settings after reinitializing as well, it was only done after initialization

        Add support for updating text candidates by calling into UIKeyboardImpl when changing the selection via
        accessibility UI (e.g. when using Switch Control). To achieve this, we add a new EditorState flag that indicates
        whether or not the EditorState change was triggered by accessibility; in WKContentView, we then consult this
        flag and call `-beginSelectionChange/-endSelectionChange` in the case where the updated editor state change was
        triggered by accessibility and we're also not already in the scope of another selection change or gesture-based
        selection change.

        Note that the latter part of the check is critical in order to avoid deadlocks in UIKeyboardTaskQueue; see
        r246013, r246425 and r246665, which introduced and later reverted a similar mechanism for updating
        UIKeyboardImpl, but after every selection change.

        Add a new `unsigned` flag, `_selectionChangeNestingLevel`, that lets us know if we're expecting an eventual call

        `_selectionChangeNestingLevel` to 0 when cleaning up the interaction after web process termination, because
        the completion handlers that contain all the balanced calls to `-endSelectionChange` should be invoked after
        such an event anyways.

        (-[WKContentView _selectionChanged]):

        If the `triggeredByAccessibilitySelectionChange` bit is set on the incoming (post layout data) EditorState and:
        (1) UIKit isn't in the middle of handling a gesture that modifies the selection, and...
        (2) We aren't expecting a call to `-endSelectionChange`.

        ...then we force UIKeyboardImpl to reload its UI (text suggestions, B/I/U state, etc.) using the incoming
        EditorState. This allows accessibility-driven selection changes using Switch Control to behave like gesture-

        (3) We've scheduled an editor state update that was triggered by accessibility.

        rdar://80663917

        Reviewed by Tim Horton.

        This started happening after the changes in r277820, since UIHoverGestureRecognizer contained several internal
        facilities in UIKit for avoiding failure dependencies to other (non-hover) gestures. After removing the
        subclass, various UIKit gestures now attempt to add failure requirements to WKMouseGestureRecognizer, thereby
        linking WKMouseGestureRecognizer to other gestures in the gesture dependency graph.

        This means that all gestures connected to the same subgraph as WKMouseGestureRecognizer are unable to be reset
        until WKMouseGestureRecognizer transitions to either Ended or Failed state; however, since this only happens
        once the trackpad goes into idle state, these subgraph-connected gestures can effectively only recognize once
        per trackpad interaction (resetting only after the trackpad goes idle). Since scroll view pan gesture
        recognizers are indirectly connected to WKMouseGestureRecognizer in Slide Over mode, this manifests in scrolling
        being unresponsive after an initial scroll gesture has ended.

        To address this, we subclass UIHoverGestureRecognizer once again, and (unfortunately) also restore the IPI
        override for `-_shouldReceiveTouch:forEvent:recognizerView:`, to ensure that we're still able to detect and
        dispatch `mousedown` and `mousemove` events.

        Instead of "display list backed RemoteLayerBackingStore" being its own

        In order to correctly avoid the note overlay that can potentially obscure the web view,
        we need to pipe the scrolling through the UI process. This patch does that work
        and will be followed up shortly by one that does the actual work of overlay avoidance.
        For iOS, this just uses the main frame UI Scrolling that we already use, but for

        [iOS] WKMouseGestureRecognizer should not have failure requirements on WKDeferringGestureRecognizer

        Avoid adding a gesture failure requirement between any WKDeferringGestureRecognizers and
        WKMouseGestureRecognizer; It doesn't make sense to claim that WKMouseGestureRecognizer should only recognize
        once active touch events have been handled by the web page. Under normal circumstances, this gesture failure
        requirement is actually completely benign, since touch events should never be received by
        WKMouseGestureRecognizer in the first place, and when using a trackpad, deferring gesture recognizers are not
        triggered.

        However, if an app were to (hypothetically) swizzle out `-gestureRecognizer:shouldReceiveTouch:` to force
        WKMouseGestureRecognizer to receive normal (non-trackpad) touch events, this could cause nearly all gesture
        recognizers in the window to become unresponsive, since WKMouseGestureRecognizer would be stuck in Changed state
        long after other gestures in the same subgraph have transitioned to Ended or Failed state, thereby preventing
        all of these gestures from being reset to Possible state.

        Add initial support for BroadcastChannel behind a runtime flag, off by default:
        - https://html.spec.whatwg.org/multipage/web-messaging.html#broadcasting-to-other-browsing-contexts

        Both Firefox and Blink have been supporting BroadcastChannel for a long time.

        The implementation is complete and spec-compliant. It works both in Window and Worker environments,
        in WebKit1 and WebKit2. However, the feature is off-by-default because of privacy concerns that have
        not been addresssed yet:
        - https://github.com/whatwg/html/issues/5803

        We should be able to add partioning to address the privacy concerns and ship this later on. In the mean
        time though, having a working BroadcastChannel implementation in the context of layout tests is already
        very useful because a lot of Web-Platform-Tests are relying on it to test other Web features. This means
        better test coverage for WebKit.

        Currently we abort IDB transactions and suspend IDB thread synchronously in NetworkProcess::prepareToSuspend.
        As UI process does not know the file locking state in network process now (because network process tracks
        the state and takes the assertion by itself), UI process may send non-imminent PrepareToSuspend more often,
        and we may abort transaction too aggressively (e.g. UI process may send the message as soon as app is in 
        background). To fix the possible regression of data loss, we will schedule a task with 5s delay to abort
        transactions after prepareToSuspend. In this case, transactions finished in 5s can have a chance to finish.

        Reviewed by Michael Catanzaro.

        Currently, when we emulate mouse events for touch, we send events with touch
        pointer type, however the way we do it doesn't really match how touch type
        events are supposed to behave: for example, we won't send a press event until
        a finger release, and will then send both together. And touch pointer type
        events are also supposed to support multitouch (or at least they do in iOS),
        while with this scheme they really can't.

        Not only all of this produces weird results for pointer events, but the actual
        mouse emulation doesn't really work as intended. For example, when tapping
        empty space on the page, and then a link, the latter won't do anything.
        Meanwhile, it's possible to accidentally open a link while pinch zooming.

        Switch back to emulating mouse pointer type events for now, as it was before
        the rewrite to avoid this. Touch pointer type events don't work properly
        anyway.

        Reviewed by Tim Horton.

        Make it possible to diagnose issues where the GPU Process is stuck (e.g. failing to acknowledge context flushes
        from the web process) by dumping information about the states of all RemoteRenderingBackends in the GPU process.
        See comments below for more detail.

        * GPUProcess/GPUConnectionToWebProcess.h:
        (WebKit::GPUConnectionToWebProcess::remoteRenderingBackendMap const):

        Expose this const getter, so that GPUProcess can iterate over remote rendering backends when collecting
        diagnostic information in `additionalStateForDiagnosticReport()`.

        * GPUProcess/GPUProcess.cpp:
        (WebKit::GPUProcess::initializeGPUProcess):
        * GPUProcess/GPUProcess.h:
        * GPUProcess/cocoa/GPUProcessCocoa.mm: Added.
        (WebKit::GPUProcess::additionalStateForDiagnosticReport const):

        Override this method and return a dictionary containing information about each RemoteRenderingBackend for all
        GPUConnectionToWebProcesses. This is an example of a state dictionary:

        ```
        {
            "RemoteRenderingBackend states" =     {
                <WP ID> =         {
                    <RRB ID> = FinishedReplayingDisplayList;
                };
            };
        }
        ```

        Importantly, this reveals RemoteRenderingBackends that are stuck waiting for newly created display list item
        buffers, missing cached resources, or destination image buffers (essentially a special case of "missing cached
        resources"), and also cases where display list playback infinitely loops or otherwise hangs.

        (WebKit::RemoteRenderingBackend::lastKnownState const):
        (WebKit::RemoteRenderingBackend::updateLastKnownState):

        Add a state flag to RemoteRenderingBackend, so that it can remember its last known state. This state is updated
        when entering or exiting the main display list processing loop (`wakeUpAndApplyDisplayList`); if we're about to
        go to sleep with pending wakeup arguments, then we'll set the last known state to one of the `WaitingFor_______`
        states.

        This state is wrapped in an Atomic, since it's only updated from the rendering backend's background queue, but
        it's only read from within the OS state handler block on the main queue.

        * GPUProcess/graphics/RemoteRenderingBackend.h:
        * GPUProcess/graphics/RemoteRenderingBackendState.h: Added.

        correlate with information from GPU Process state dumping above.

        r279720 made it so that `CaptionUserPreferencesMediaAF::setCaptionDisplayMode` no longer

        as a way of preventing the WebProcess from trying to read back that value after it's set,
        instead having the UIProcess send `Messages::WebProcess::SetMediaAccessibilityPreferences`
        whenever this changes to update that cached value. Unfortunately, because the WebProcess
        needs to read this value immediately after changing it, this IPC round trip causes the
        WebProcess to read the old value, which results in no observable changes. In order to fix
        this, notify `CaptionUserPreferences` that `captionPreferencesChanged` when the above IPC
        message is received (which will also handle cases when the value changes outside WebKit).

        [WK2] Push OS state dumping logic down from WebProcess to AuxiliaryProcess
        https://bugs.webkit.org/show_bug.cgi?id=227916

        Reviewed by Tim Horton.

        Refactor state dumping registration code in preparation for supporting state dumping in the GPU process on Cocoa
        platforms when triggering system diagnostics. The logic that currently lives in
        `WebProcess::registerWithStateDumper` is comprised of two parts: (1) code that calls `os_state_add_handler` with
        a `os_state_data_t` provider, and (2) code that builds a dictionary containing diagnostic information specific
        to the web process.

        Since GPUProcess will require only the former, we hoist logic for (1) into the superclass (AuxiliaryProcess) so
        that both GPUProcess and WebProcess can invoke it, and refactor (2) to be a virtual method that may be
        overridden by subclasses to provide process-specific information.

        `m_cachedState.naturalSize`. So the next `MediaPlayerPrivateRemote::UpdateCachedState`

        Make a couple of minor adjustments to deal with the fact that `-contentInset` includes system content insets

        Only apply `-safeAreaInsets` on top of `-contentInset` when computing the total scroll view content inset on
        watchOS (as opposed to applying both `-safeAreaInsets` and `-_contentScrollInset`); this is because
        `-contentInset` on watchOS is actually equivalent to `-_effectiveContentInset` on other iOS-family platforms, so
        additionally adding `-_contentScrollInset` here would result in the scroll content inset being double-counted.

        In the case where the WebKit client explicitly sets the scroll view's content insets using `-[WKScrollView
        setContentInset:]`, set a flag (`_contentInsetWasExternallyOverridden`) and immediately revert any internally
        specified `-_contentScrollInset` on WKScrollView. Due to the swizzled implementation of `-[UIScrollView
        contentInset]` described above, it's practically impossible for any client to use `-setContentInset:` correctly
        when there is a nonzero `-_contentScrollInset` on watchOS, so preferable to simply get out of the way of the
        client in this scenario.

        In the context of _SFNanoBrowserViewController, this ensures that scroll view content inset adjustment logic in
        Safari doesn't inadvertently cause horizontal content insets to increase by `-_contentScrollInset` every time
        `-[WKScrollView setContentInset:]` is invoked by the client.

        Reviewed by Dean Jackson.

        PlatformXRSystem and PlatformXRSystemProxy are only compiled in Cocoa platform while WPE uses OpenXR,
        which only has code in WebCore. In order to run WebKit based WebXR on non-cocoa VR Standalone devices
        we also need to split the code and IPC messages between UIProcess/WebProcess.

        The existing PlatformXRSystem/PlatformXRSystemProxy pattern fits very well to the VR standalone scenario.

        We have a frame counter which makes sure that fonts which haven't been used in n frames get released.
        However, we currently only update the frame counter when we release fonts.
        This means that the frame counter stays 0 forever. And we never release any fonts.

        The fix is just to increment the frame counter even if we don't release any fonts.

        No new tests because there is no architectural behavior change.

        [GTK] Touchscreen navigation swipe doesn't work when the page scrolls horizontally
        https://bugs.webkit.org/show_bug.cgi?id=227691

        Reviewed by Michael Catanzaro.

        When the page scrolls horizontally, we have a separate code path for events that
        WebCore didn't handle and which are considered safe to use to start a swipe
        gesture. Unfortunately, that code relies on the NativeWebWheelEvents containing a
        GdkEvent, which is only the case for actual scroll events, but not synthesized
        scroll events on touchscreen, and the needed info (input source type and a proper
        timestamp instead of the truncated one wallTimeForEventTime() produces) is not
        stored in NativeWebWheelEvent.

        While we don't have GdkEvents for every situation we synthesize wheel events in,
        we do have them for touchscreen gestures. They aren't GdkScrollEvents, but that
        isn't a problem - the only things we use that are specific to GdkScrollEvent are
        scroll deltas and whether it's a scroll stop event, and that's also stored in
        NativeWebWheelEvent, and we only need GdkEvent for the time and input source type,
        where the event type doesn't really matter.

        Since touch GdkEvents are controlled via event sequences rather than stop/propagate
        return values, don't try and propagate them if web process has returned them: we've
        already claimed their sequence before sending them to web process, so they will be
        of no use to other widgets.

        [watchOS] Tapping "Done" in Scribble when focusing an editable element should dismiss Quickboard

        Reviewed by Tim Horton and Devin Rousso.

        After using PUICQuickboardMessageViewController's PUICTextInput-based mode for presenting Scribble UI, we fail
        to dismiss PUICQuickboardMessageViewController underneath `-dismissAllInputViewControllers:`, since Quickboard
        is not the top-most view controller (instead, it ends up being PUICQuickboardRemoteViewController). As a result,
        the call to `-dismissViewControllerAnimated:completion:` on the fullscreen input view controller ends up being
        dropped on the floor.

        Prior to adopting PUICQuickboardMessageViewController and remote text input on watchOS, this worked because the
        delegate method `-quickboard:textEntered:` would only be invoked after the front-most view controller was done
        dismissing, such that calling `-dismissViewControllerAnimated:completion:` on the fullscreen input view
        controller would (correctly) dismiss it.

        We can address this by checking whether the fullscreen input view controller itself has a presented view
        controller in `-dismissAllInputViewControllers:`, and dismissing that first if necessary.

        WKWebView clients should be able to disable Extensible SSO authentication flows, so exposing the internal
        mechanism as SPI. This is especially important for use cases where a WKWebView will be used to load content
        without being attached to a Window, since a Window is required to present the Extensible SSO authentication
        UI. Without a Window, WebKit will wait for a Window to be attached causing loads to timeout. By adopting this
        API, developers can opt out of Extensible SSO, allowing loads to fail quickly rather than waiting for a timeout.

        When injecting Live Text into images, we currently assume that all pieces of recognized text from VisionKit are

        To fix this, we add a bit for each TextRecognitionWordData, to indicate whether that word should be followed by
        whitespace in the image overlay. When converting VKWKTextInfo into TextRecognitionWordData, we then set this bit
        to `true` only if the word is the first on a line of text that is preceded by another line, or there exists

        [iOS] Have ProcessAssertion take the RunningBoard assertion asynchronously by default
        https://bugs.webkit.org/show_bug.cgi?id=225324
        <rdar://76972252>

        Reviewed by Geoffrey Garen.

        Have ProcessAssertion take the RunningBoard assertion asynchronously (on a background thread) by
        default as we have evidence that doing so on the main thread is bad for performance and may
        negatively impact launch time.

        When constructing a ProcessAssertion, the caller can now indicate if it wants the assertion to be
        taken asynchronously (default) or not. Bug 227552 is an example of a case where we still want to
        take the assertion synchronously (because we're not on the main thread and we need to make sure
        we have the assertion before proceeding).

        The caller can also provide a completion handler that will get called once the RunningBoard is
        taken. Note that the RunningBoard async API ([RBSAssertion acquireWithInvalidationHandler]) does
        not provide a way for us to know when the assertion is taken. For this reason, ProcessAssertion
        keeps using the RunningBoard sync API ([RBSAssertion acquireWithError:]) but calls in on a
        background queue.

        For the UIProcess's background task though, we don't need to know when the assertion is taken
        so we can use the RunningBoard async API.

        Note that the previous iteration of this patch had a bug where the ProcessThrottler would release
        its previous assertion before the new one is taken (asynchronously) when changing the assertion
        type (e.g. foreground to background). This is addressed in this patch. ProcessThrottler now passes
        an acquisition handler when constructing the ProcessAssertion and only releases its previous
        assertion once the acquisition handler for the new one is taken.

        loadSimulatedRequest: should do same delegate callbacks as loadHTMLString and loadData
        https://bugs.webkit.org/show_bug.cgi?id=227599

        Reviewed by Chris Dumez.

        Share more code with loadData and loadHTMLString to prevent such errors.

        Before this change we set SubstituteData.failingURL, which in FrameLoader::PolicyChecker::checkNavigationPolicy
        makes it behave more like _loadAlternateHTMLString which doesn't call decidePolicyForNavigationAction and does
        add a back/forward entry. We want it to behave more like loadHTMLString, which does call decidePolicyForNavigationAction
        and doesn't add a back/forward entry. Except we do want it to add a back/forward entry. This patch is to accomplish that.

        In order to continue making a back/forward list item with loadSimulatedRequest, we need to use
        WebCore::SubstituteData::SessionHistoryVisibility::Visible for its calls and also API::SubstituteData
        needs to remember that we initially used that for when we go back to a back/forward list item from
        that data.  In order to keep binary compatibility with existing apps, loadData and loadHTMLString
        need to continue using WebCore::SubstituteData::SessionHistoryVisibility::Hidden.

        [GTK] Navigation swipe gesture can be triggered with mouse
        https://bugs.webkit.org/show_bug.cgi?id=227678

        Reviewed by Carlos Garcia Campos.

        Originally, the navigation swipe gesture had a few checks to only make it possible to
        trigger it with a touchpad or touchscreen, with an exception for simulated swipes
        where we couldn't set the source easily.

        During the rewrite in https://bugs.webkit.org/show_bug.cgi?id=212324, the check got
        dropped, but it has a good reason to be there: not all devices are capable of
        performing a gesture. Touchpads and touchscreens should be fine, trackpoints are
        finicky, though can still technically work, but mouse are a no-go. While they can
        start a swipe, they will never end it and the gesture will get stuck.

        So, add the check back. Don't bother with the scroll direction this time though, while
        that check made sense when it got added, at some point since then all scroll events
        had GDK_SCROLL_SMOOTH direction and just set their deltas to (1, 0), (-1, 0), (0, 1)
        or (0, -1), so that check stopped working, and the source type check should filter
        mouse events anyway.

        [iOS] Augment -_webView:didNotHandleTapAsMeaningfulClickAtPoint: to include meaningful taps
        https://bugs.webkit.org/show_bug.cgi?id=227666
        rdar://80094962

        Reviewed by Tim Horton.

        The private UI delegate method `-_webView:didNotHandleTapAsMeaningfulClickAtPoint:` is currently only invoked
        when a tap was not handled as a "meaningful" synthetic click (where the notion of "meaningful" is heuristically
        determined). However, in order to support revised tab pill minimization behaviors, Safari requires knowledge of
        taps that were handled as meaningful clicks as well.

        To support this, replace what is currently `-_webView:didNotHandleTapAsMeaningfulClickAtPoint:` with another
        delegate method, `-_webView:didTapAtPoint:withResult:`, that is always invoked when a tap gesture is recognized
        in the web view. The `result` parameter, a new `_WKTapHandlingResult` enum, then indicates to the client how the
        tap was handled; this currently includes 3 values: one to indicate that the tap gesture did not result in a
        synthetic click being dispatched, and two more to indicate whether the synthetic click that was dispatched as a
        result of the tap was "meaningfully" handled.

        To facilitate the transition from `-_webView:didNotHandleTapAsMeaningfulClickAtPoint:` to the new SPI, we still
        call the old SPI as long as the tap handling result type is not equal to TapHandlingResult::MeaningfulClick;
        however, mark the old SPI as deprecated with `-_webView:didTapAtPoint:withResult:` as the replacement.

        Selecting or dragging images that contain recognizable text is difficult in Mail compose
        https://bugs.webkit.org/show_bug.cgi?id=227544

        Reviewed by Devin Rousso.

        Long pressing images in editable content on iOS initiates dragging, and a tap-and-half gesture over the image
        selects the entire image. Both of these are common interactions for image attachments in Mail compose that
        take precedence over new Live Text interactions, so there's no advantage to triggering image analysis on images
        in editable content.

        Avoid doing this extra work by adjusting `-imageAnalysisGestureDidBegin:` to bail early if the image is inside
        editable content.

        In iOS 15, <select> options are displayed in a context menu. WebKit does

        [Cocoa] Migrate WebRTC UDP socket handling to NW API
        https://bugs.webkit.org/show_bug.cgi?id=227210

        Reviewed by Eric Carlson.

        Migrate UDP socket handling from WebRTC physical socket server to nw API for Cocoa ports.

        For each UDP socket opened, we open a nw_listener that will listen to inbound connections.
        On inbound connection, we receive a nw_connection that we store in a address -> connection map.

        Whenever sending a packet, we look at the remote address.
        If needed, we create a nw_connection to that particular remote address and store it in the address -> connection map.
        We then use the pre-existing or newly created nw_connection to send the packet.

        Make sure to cancel NW connection in case of failure before releasing the socket.

        Covered by existing tests

        On the WebKit side, in the UIProcess, we receive a message from the WebProcess when the ASVInlinePreview in that process
        was created with its generated UUID. We provide this to the ModelElementController, set the remote connection up and load
        the file. When those tasks complete successfully we message back the WebProcess with the UUID and the provided ElementContext
        to talk back to the HTMLModelElement instance that initiated the message to the UIProcess in the first place.

        Displaying a model element in fullscreen requires making some calls on the ASVInlinePreview object
        created by a WKModelView. We send the content layer ID we receive through an IPC call from the
        WebProcess to the new ModelElementController. We then look at the remote layer tree for a node
        matching that ID and find its related UIView. If we find a WKModelView, as expected, we can carry 
        on and call -[ASVInlinePreview createFullscreenInstanceWithInitialFrame:previewOptions:completionHandler:]
        to enter fullscreen using the presentingViewController provided by the UI client, and then observe
        when we exit fullscreen using -[ASVInlinePreview observeDismissFullscreenWithCompletionHandler:]
        to make sure the presenting view controller is removed.

        [Cocoa] Migrate WebRTC UDP socket handling to NW API
        https://bugs.webkit.org/show_bug.cgi?id=227210

        Reviewed by Eric Carlson.

        Migrate UDP socket handling from WebRTC physical socket server to nw API for Cocoa ports.

        For each UDP socket opened, we open a nw_listener that will listen to inbound connections.
        On inbound connection, we receive a nw_connection that we store in a address -> connection map.

        Whenever sending a packet, we look at the remote address.
        If needed, we create a nw_connection to that particular remote address and store it in the address -> connection map.
        We then use the pre-existing or newly created nw_connection to send the packet.

        Make sure to cancel NW connection in case of failure before releasing the socket.

        ASVInlinePreview instances allow for UITouch and UIEvent objects to be forwarded in order to manipulate

        This allows multiple <model> elements to be manipulated at once.

        Adopt FigThread{Un,}RegisterAbortAction() when blocking against track parsing.

        CoreMedia will attempt to abort reads during AVPlayer teardown, but because the parsing
        thread is blocked on a Condition variable in WebKit code, the abort request has no effect.
        Adopt methods from CoreMedia to run code during an abort request, and wrap these calls in a
        stack-based object. The new AbortAction object takes a Condition variable to notify during
        an abort, and its aborted() state can be queried by the Condition's predicate.

        REGRESSION (r279310): Occasional crash when focusing login fields on iPad with a software keyboard
        https://bugs.webkit.org/show_bug.cgi?id=227472
        rdar://79876040

        Reviewed by Tim Horton.

        I added a mechanism in r279310 to defer calling `-[WKContentView _setSuppressSoftwareKeyboard:NO]` until we've
        gotten a response from the web process containing an up-to-date autocorrection context. However, in the case
        where the WKWebView client sets `_suppressSoftwareKeyboard` to `YES` and then immediately to `NO` underneath the
        scope of a call to `-_webView:willStartInputSession:`, we'll end up calling into `-_setSuppressSoftwareKeyboard:`
        inside the scope of `-requestAutocorrectionContextWithCompletionHandler:`, when we've received an
        autocorrection context while sync-waiting. This is problematic because it breaks UIKeyboardTaskQueue's state,
        since the call to `-_setSuppressSoftwareKeyboard:` will attempt to enqueue a new task after the previous task's
        context has already returned execution to the parent.

        To fix this, we instead invoke `self._suppressSoftwareKeyboard = NO;` *before* calling the completion block in
        `-_handleAutocorrectionContext:`. This allows the request for an autocorrection context underneath
        `-_setSuppressSoftwareKeyboard:` to be handled (and completed) as a child task of the previous task, which keeps
        UIKeyboardTaskQueue in a valid state.

        WKWebViewConfiguration._attributedBundleIdentifier makes us use a SessionSet per WKWebView.
        When the WKWebView is destroyed with an open WebSocket, there's a race condition between the

        NetworkConnectionToWebProcess::didClose message coming from the closing of the web process, which
        calls NetworkSessionCocoa::removeWebSocketTask which currently expects the WebSocketTask to still
        be there.  Instead, keep a WeakPtr<SessionSet> and don't remove it if the SessionSet's map is gone.

        I wrote an API test that hits this condition sometimes when HAVE_NSURLSESSION_WEBSOCKET is true.

        Add a new WKModelView class which manages an ASVInlinePreview and displays its layer.
        The current incarnation of the ASVInlinePreview SPI requires a URL to a file to specify
        the resource, so we write a file to the temporary directory added in 279267 with the data
        wrapped in the Model object passed through the remote layer tree. Ultimately we will be
        able to use an SPI that does not require a file and instead will allow data to be passed
        directly, this is purely for a temporary experimentation.

        [iOS] Safari sometimes hangs under sync IPC in `-[WKWebView _setSuppressSoftwareKeyboard:]`
        https://bugs.webkit.org/show_bug.cgi?id=227424
        rdar://79745385

        Reviewed by Tim Horton.

        When activating streamlined AutoFill, Safari calls UIKit SPI (`-_setSuppressSoftwareKeyboard:`) on WKWebView to
        ensure that the normal software keyboard doesn't briefly appear instead of the AutoFill input view; after
        requesting AutoFill credentials, Safari then stops suppressing the software keyboard by setting the SPI property
        back to NO. In WebKit, we override `-[WKWebView _setSuppressSoftwareKeyboard:]`, such that WKContentView's
        keyboard suppression state follows the web view's state (this is necessary, since WKContentView is the actual
        `-firstResponder` when editing focused text inputs). However, when changing software keyboard suppression from
        YES to NO, UIKit reloads input views and (in the process) calls into
        `-requestAutocorrectionContextWithCompletionHandler:`, which then makes a sync IPC call into the web process.

        To avoid this sync IPC call, we refactor the implementation of `-[WKWebView _setSuppressSoftwareKeyboard:]`,
        such that we don't immediately attempt to unsuppress the software keyboard by calling into WKContentView.
        Instead, we asynchronously request an autocorrection context from the web process, and then call
        `-[WKContentView _setSuppressSoftwareKeyboard:NO]` after the autocorrection context request completes (using
        the last known autocorrection context data in the UI process rather than making a sync IPC call).

        * UIProcess/API/ios/WKWebViewIOS.mm:

        Add a new helper that keeps WKContentView's software keyboard suppression state in sync with the WKWebView's
        software keyboard suppression state. In the case where we're supressing the software keyboard, we can simply
        call into `-[WKContentView _setSuppressSoftwareKeyboard:]` right away, since UIKit won't try to request an
        autocorrection context.

        However, in the case where we're unsuppressing the software keyboard, set a new flag, don't immediately forward
        the call to WKContentView. Instead, set the `_unsuppressSoftwareKeyboardAfterNextAutocorrectionContextUpdate`
        flag to YES and call into WebPageProxy to request an updated autocorrection context. Upon receiving the response
        in `-[WKContentView _handleAutocorrectionContext:]`, we then unset the flag and unsuppress the software keyboard
        (crucially, using `_lastAutocorrectionContext` instead of making a synchronous call back to the web content
        process).

        Using a video as a source for a WebGL texture is slow and hangs on iOS 15
        https://bugs.webkit.org/show_bug.cgi?id=227081

        Reviewed by Eric Carlson.

        In current form, media is decoded in GPU process and WebGL is processed
        in Web process.

        Video frame transfer from GPU process to Web process would fail when
        WebGL tried to copy the video frame to a texture. The failure was
        artificial, due to use of WebCore::IOSurface as a unneeeded helper
        to convert CVPixelBufferRef to a cross-process object.

        The failure would occur when AVPlayerItemVideoOutput
        would generate a CVPixelBufferRef without color space information. Creating
        WebCore::IOSurface out of this would fail. WebCore::IOSurface
        has always a color space. The failure is not significant, as WebCore::IOSurface
        was only used as a convenience.

        This would cause performance regression when WebGL would
        fall back to software conversion fallback. This callback did work
        as it obtains the image through "get last frame as native image"
        API.

        In takeSnapshotWithConfiguration() we call callSnapshotRect() inside the

        callSnapshotRect() calls the client callback which may call directly or
        indirectly addCommitHandler. But it is prohibited by CA to add a commit
        handler while processing a registered commit handler.

        The fix is to postpone calling callSnapshotRect() till CATransaction

        Message dropped when restoring webpages.
        https://bugs.webkit.org/show_bug.cgi?id=227278

        Reviewed by Tim Horton.

        The message to initialize the state of highlightVisibility is dropped sometimes, but
        fortunately, there is no need to pass the current state when initializing the
        HighlightObserver, as WebPageProxy::creationParameters will obtain the correct
        highlight state on initialization after r279078.

        [Live Text] [macOS] Add an internal option to disable inline text selection in images
        https://bugs.webkit.org/show_bug.cgi?id=227265
        rdar://79460142

        Reviewed by Tim Horton.

        Refactor Live Text and Visual Look Up logic, such that the ability to select text inside of images is behind an
        internal feature flag that can be toggled at runtime. When Live Text is disabled, we'll unconditionally show the
        "Look Up" context menu action using the more generic title "Quick Look". This "Quick Look" action is then
        retitled to either "Look Up in Quick Look" or "Select Text in Quick Look" once image analysis completes.

        indicate whether or not it should request text recognition results or visual search results. We use this for the
        "Quick Look" context menu action when inline text selection is disabled, in order to retitle the item to "Select
        Text in Quick Look".

        Add logic to either remove and reinsert the "Look Up" context menu action (if inline text selection in images is
        enabled), or to promote the "Quick Look" context menu action to either "Select Text in Quick Look" or "Look Up
        in Quick Look" in the case where inline text selection in images is disabled.

        Note that when inline text selection in images is disabled, we'll first check for visual search results before
        checking for text. This is because visual search results will take precedence over text selection (i.e., we'll
        show "Look Up in Quick Look" even if both visual search results and text is present), so we can avoid performing
        text analysis in the case where we already found visual search results.

        Sending a SharedBuffer across IPC is implemented by having the receiver map a shmem into its address space. On
        the sender's side, the shmem still exists, and a compromised web process could scribble data into it after
        sending it. So, when the GPU process receives the font data, we need to make a copy of it locally to make sure
        the data can't change out from under us.

        No new tests because there is no behavior change.

        1) Remove maximumUnusedFontCountToSkipRemoval because 
           'unusedFontCount < maximumUnusedFontCountToSkipRemoval' can't be true
           since both unusedFontCount and maximumUnusedFontCountToSkipRemoval are
           unsigned and maximumUnusedFontCountToSkipRemoval is equal to zero.
           So they can only be equal and we can replace this by '!unusedFontCount'.

        2) RemoteResourceCacheProxy::cacheFont() assumes if the font is cached in
           m_fontIdentifierToLastRenderingUpdateVersionMap then it is also cached
           in GPUP. We have to keep this assumption correct by removing the 
           corresponding entries from m_fontIdentifierToLastRenderingUpdateVersionMap.

        3) RemoteResourceCacheProxy::didFinalizeRenderingUpdate() needs to reset

        NSURLSession's WebSocket implementation currently has maximumMessageSize's default value at 1MB.
        Our CFReadStream-based WebSocket implementation had no message size limitation, so set it to 0 to remove the limit.

        Writing a test for this was tricky because our WebSocket LayoutTests use the deflate extension.  I wrote an API test
        that implements a simple WebSocket exchange and verifies each byte is what we expect.
        The test used to fail using our NSURLSession-based WebSocket implementation but now passes everywhere.

        [iOS] Fullscreen video playback gets stuck after interacting with the playback controls
        https://bugs.webkit.org/show_bug.cgi?id=227047

        Reviewed by Eric Carlson.

        When we scrub a playing video, the video element may enter a temporarily stalled
        state - the player is still playing, but it does not have enough data. In WebKit,
        the `rate` of the player will be 0. But we cannot set the rate of `WebAVPlayerController`
        to 0 in this case, because AVKit will believe the video playback is paused when
        its rate is 0. In r261587, we defined a magic rate (0.00000001f) for this case.

        Unfortunately, with the changes in r275956, `WebAVPlayerController` will
        align its `defaultPlaybackRate` with `rate` when `rate` is not 0. Under stress
        tests, e.g., keep scrubbing a video, a video element will eventually enter a state
        in which both `defaultPlaybackRate` and `rate` are the magic rate. And the video
        appears to be stuck for users.

        To fix the issue, this patch removes the magic rate and defines a new state: `stalled`.
        A video will be in the stalled state when it is playing but does not have enough data.
        WebKit will only change the rate of `WebAVPlayerController` when the video
        is not stalled.

        To avoid potential problems due to the conversions between "float" and "double"
        back and forth, this patch updates the types of `playbackRate` and `defaultPlaybackRate`.

        [WPE] Rework touch-based gesture controller
        https://bugs.webkit.org/show_bug.cgi?id=226456

        Reviewed by Alejandro G. Castro.

        Rename WPE's ScrollGestureController to TouchGestureController since now
        it also handles production of touch-based click events.

        TouchGestureController now internally manages all the related state,
        tracking the touch interaction and determining whether it progresses
        into a scrolling gesture or whether, upon finishing, it should be
        translated into a simple click event.

        In PageClientImpl, any unhandled event is pushed into
        TouchGestureController and a variant of different outcomes is returned.
        No-event result is ignored, and click or axis events are dispatched as
        appropriate.

        In WPEView, where the touch events arrive into the engine, we keep the
        shortcut where touch events are piped directly into the controller if
        said controller is already gesturing scrolling behavior. In that case
        the touch events are not dispatched into the engine, with the exception
        of touch-up events which are, to provide matching closure for the
        touch-down events.

        Restrict video decoders and disable hardware image decoders.

        A temp extension is created for the service "com.apple.trustd.agent" to
        allow temporarily calling FigPhotoSupportsHEVCHWDecode(). This function
        needs access this service but we have recently closed access to it.

        FigPhotoSupportsHEVCHWDecode() sets a local static variable by using the 
        service "com.apple.trustd.agent" when it is called for the first time.
        Our purpose of calling it in this context is to initialize the static
        variable only. And this is why we do not use its return value.

        This solution is fragile. If MediaToolbox is changed such that it needs
        'com.apple.trustd.agent' while decoding an image, the decoding will fail.

        To be extra careful, instead of just assuming that moveFile will always succeed,
        when moveFile fails, try to delete the legacy path (which has a ContentExtension- instead of ContentRuleList- prefix)
        and fail the lookup.  This will only happen in Safari, which was the only client of _WKUserContentExtensionStore.
        The legacy file is not useful to us because in r275078 I incremented CurrentContentRuleListFileVersion so the bytes on disk
        need to be recompiled anyways.  Safari already has logic to recompile it.  This was just an attempt to use what we have and
        not leave anything behind.

        [watchOS] Reenable modern text input UI for non-numeric text input types
        https://bugs.webkit.org/show_bug.cgi?id=226988
        rdar://78102953

        Reviewed by Tim Horton.

        Refactor text input logic on watchOS such that we're able to present the new ("modern") UI for scribble text
        input on watchOS 8, rather than legacy (in-process) scribble UI. Overall, this patch removes
        WKQuickboardListViewController altogether. This had two subclasses: WKSelectMenuListViewController (used for
        focused single and multiple select elements) and WKTextInputListViewController (used for text input types).
        WKSelectMenuListViewController now inherits directly from PUICQuickboardListViewController, and
        WKTextInputListViewController now inherits from PUICQuickboardMessageViewController; this inheritance from
        PUICQuickboardMessageViewController instead of PUICQuickboardListViewController allows the
        WKTextInputListViewController to show text suggestions using `-setMessages:` on
        PUICQuickboardMessageViewController, instead of relying on custom WebKit code to insert text suggestions.

        This means that we move the following pieces of functionality out of WKQuickboardListViewController, and into
        either WKSelectMenuListViewController or WKTextInputListViewController:

        1. Support for inserting and updating context views (i.e. the domain name header view in Quickboard) =>
        WKTextInputListViewController.

        2. Logic for determining whether or not we should show language selection UI => WKTextInputListViewController.

        3. Support for laying out custom collection view cells in Quickboard => WKSelectMenuListViewController.

        This allows PUICQuickboardMessageViewController to show a native text field containing the input text inside
        quickboard, which (when tapped) presents modern text input UI.

        Since showing the text field is apparently mutually exclusive to showing a tray view, we additionally override
        `-shouldShowTrayView` and return NO for non-numeric text inputs.

        There's no need to override this delegate method anymore, since the PUICTextInputContext's `-initialText` is
        sufficient to ensure that the scribble text input UI is prepopulated with the focused text field's initial text
        content.

        (-[WKTextInputListViewController reloadTextSuggestions]): Deleted.

        Rename this to `-updateTextSuggestions:`, and make it take a list of UITextSuggestions. This makes the code a
        bit easier to follow and allows us to remove the `-textSuggestionsForListViewController:` delegate method.

        Following bug #225396, the remote/proxy MediaPlayer readyState became decoupled
        from the currentTime. In the scenario where a time update was pushed from the
        GPU to the WebContent process, followed by a change of readyState status; should
        the HTMLMediaElement query the MediaPlayer's time in-between those two IPC calls,
        it would be possible for the time to be incorrectly estimated as it assumed it
        had progressed since it received the update.
        Additionally, it was assumed that the only case where the time won't progress
        was if the media element was explicitly paused. This was incorrect it could
        have stalled due to the lack of data such as commonly happen with MSE.
        We add in the time update IPC message a boolean indicating if the GPU's
        MediaPlayer is either stalled or paused and that the time shouldn't advance.
        While this new boolean appears redundant with the values of the cached
        readyState/paused it differs in that timeIsProgressing is accurate at the
        moment the time update is sent and received.

        Before the change, if the page is in a bad state due to a hung GPUProcess or NetworkProcess and you'd
        reload, the reload would hang indefinitely. After the change, we'll make sure that both processes
        are still responsive when triggering the reload. If they are unresponsive, we kill them and the reload

        Add basic detection of unresponsive Network / GPU Processes
        https://bugs.webkit.org/show_bug.cgi?id=226994

        Reviewed by Geoffrey Garen.

        If a WebProcess A attempts to connect to the GPUProcess / NetworkProcess B and process B
        fails to respond within 3 seconds, we consider process B as unresponsive and terminate
        it. As a result, it will re-attempt to launch process B and connect to it again.

        This helps in the following scenario:
        1. User is in a tab and something looks broken due to the GPUProcess or NetworkProcess
           becoming unresponsive
        2. The user tries to reload the page in a new tab

        Before this patch, the tab would be similarly broken / hung because the GPUProcess or
        NetworkProcess would be unresponsive. After this patch, we would detect the process is
        hung and kill it. As a result, the page would load correctly in a new tab (with a delay).

        In a follow-up, I think we should consider doing the same thing when the user requests
        a reload, so that we don't require opening a new tab to recover. However, this keeps
        the patch small and is a decent first step.

        [watchOS] Quickboard UI for focused select elements should not allow the user to change the input language
        https://bugs.webkit.org/show_bug.cgi?id=226958

        Reviewed by Tim Horton.

        Fix a couple of bugs around focused select element UI that were introduced in watchOS 7, due to changes in
        PepperUICore. See below for details.

        * UIProcess/ios/forms/WKQuickboardListViewController.mm:
        (-[WKQuickboardListViewController initWithDelegate:]):

        Drive-by fix: remove a `USE(APPLE_INTERNAL_SDK)` guard that was (seemingly) unintentionally added in r262854.

        (-[WKQuickboardListViewController viewDidLoad]): Deleted.

        Avoid hiding the list view controller's `-headerView` when focusing select elements. In watchOS 7, the accept
        and cancel buttons are positioned inside the `-headerView`, so having this logic in the base class
        (WKQuickboardListViewController) means that the Done button in select menus does not show up. In turn, this
        means that currently, users who focus select elements must know to use the crown button to dismiss the select
        menu.

        For now, we move logic to the only other subclass of WKQuickboardListViewController,
        WKTextInputListViewController. However, note that this too is going away in an upcoming patch that refactors
        WKTextInputListViewController so that it directly subclasses PUICQuickboardMessageViewController
        instead of PUICQuickboardListViewController.

        * Platform/spi/watchos/PepperUICoreSPI.h:

        Move a declaration of `-initWithDelegate:dictationMode:` from PUICDictationViewController to
        PUICQuickboardListViewController (see the change in `-[WKQuickboardListViewController initWithDelegate:]` above).

        * UIProcess/ios/forms/WKSelectMenuListViewController.mm:
        (-[WKSelectMenuListViewController shouldShowLanguageButton]):

        Since watchOS 7, the language button is now always shown by default in PUICQuickboardListViewController, with a
        new subclassing hook to avoid showing it. It doesn't make sense to allow the user to change input languages when
        choosing options in a select menu, so we implement this and always return `NO` here.

        * UIProcess/ios/forms/WKTextInputListViewController.mm:
        (-[WKTextInputListViewController viewDidLoad]):

        After some recent PepperUICore changes, the Quickboard button for presenting the number pad when focusing a
        telephone input on watchOS 8 is missing its icon image. To fix this, stop using deprecated SPI for creating
        the list tray button, and instead use `+[PUICQuickboardListTrayButton buttonWithType:]` and `-setAction:` to
        create and set up the button.

        https://bugs.webkit.org/show_bug.cgi?id=226787

        Reviewed by Eric Carlson.

        A WebContent process will resume a video element playback after the GPU process crashes
        and restarts. During that process, the WebContent process will set category of the audio
        session, and the UI process will be asked to begin routing arbitration with the new
        category. However, the `SharedRoutingArbitrator` at the UI process will have stale
        routing arbitrator tokens, which lead to the assertion failure.

        To fix this issue, this patch cleans up the `SharedRoutingArbitrator` when the GPU
        process crashes.

        Reviewed by Darin Adler.

        We're going to disk more often for local storage operations since r276653 because we no
        longer keep items in memory. This results in a slightly increased power usage on one of
        our benchmarks. As a first step to improve this, I am reintroducing a cache of the items
        in memory, as long as the values are not too large (1Kb limit). We still go to disk to
        look up values that are larger than 1Kb to avoid regressing memory usage.

        <rdar://problem/77207322>

        Reviewed by Tim Horton.

        The VinylWall app contains a WKWebView, and uses <select> to let users
        choose options. With the new form controls on iOS, tapping on a <select>
        presents a UIContextMenuInteraction, rather than a picker wheel or
        popover. However, UIContextMenuInteraction is not supported on apps
        linked against an SDK older than iOS 14, resulting in this crash.

        To fix, perform a linked-on-or-after check before showing the new UI
        for <select> and <input type=text> with a <datalist>. If the check
        fails, fallback to the old UI. We already have this check in place for
        other context menus in `-[WKContentView _shouldUseContextMenus]`, so we
        reuse that method.

        WebKitWebView::show-option-menu has different parameters for GTK than it does for WPE. It
        seems g-ir-scanner is taking the WPE documentation and merging it with the GTK parameters.
        We can fix this by moving the introspection comment into platform-specific files.

        Additionally, let's use --warn-error to turn warnings into errors to prevent this from ever
        happening again, as we already do when generating introspection for JavaScriptCore.

        On iOS, `UIDelegate::UIClient::fullscreenMayReturnToInline()` is called when
        a video exits picture-in-picture, but not when a video exits fullscreen.
        This patch fixes that.

        We cannot add a regression test for this patch before fixing webkit.org/b/212654.

        [GTK4] Add support for navigation gestures
        https://bugs.webkit.org/show_bug.cgi?id=212327

        Reviewed by Michael Catanzaro.

        Make ViewSnapshotStore store GdkTexture instead of Cairo surfaces
        for GTK4. Split ViewSnapshotStoreGtk.cpp into GTK3 and GTK4 versions
        since they don't have much in common.

        When taking a view snapshot, render the web view into a texture.

        When starting a navigation gesture, create a render node from
        either the texture, or a fallback color, then render that instead
        of using Cairo.

        Implement the same dimming+shadow as in GTK3. This time don't bother
        with CSS, the approach we used in GTK3 doesn't work anymore, and since
        elements like scrollbars aren't themeable anyway it's not very important
        to preserve that.

        Remove a check for whether or not the clicked node is an Element; this existed because the call to
        `rootViewBoundsForElement` below takes an Element rather than just a Node; however, this method doesn't do
        anything that requires an Element instead of a Node, so we can just remove the check and refactor these static

        [iOS] Unexpected scrolling when switching focus from a text input to a select element
        https://bugs.webkit.org/show_bug.cgi?id=226657
        <rdar://problem/78290515>

        Reviewed by Tim Horton.

        When switching focus from a text input to a select element, UIKit makes
        deferred calls to `-[WKWebView inputView]` after the keyboard dismissal.
        This method calls `-[WKContentView inputViewForWebView]`, which calls
        `-[WKContentView _zoomToRevealFocusedElement]`. Consequently, these
        methods can get invoked while the context menu (dropdown) is displayed
        for a focused select element.

        In this instance, the call should be idempotent, since the focused element
        is fully visible in the viewport. However, since the context menu is visible
        and overlaps the element, our logic incorrectly determines that the element
        is obscured, leading to unexpected zooming/scrolling. To fix, we need to
        correct the logic that determines the visible portion of the view.

        Test: fast/forms/ios/form-control-refresh/select/focus-select-after-textfield.html

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

        Always use the window to determine the portion of the webview that is
        visible, rather than relying on the root view controller's top-most
        full-screen view controller's view.

        The old logic worked fine in most cases, since the root view controller
        and the top-most full-screen view controller are almost always the same.
        Furthermore, the root view controller's view usually takes up the entire
        window.

        However, when the context menu is on screen, the top-most full-screen
        view controller is an internal UIKit view controller
        (_UIContextMenuActionsOnlyViewController), and the associated view
        is the context menu view. This exposed a flaw in the existing logic, as
        visibility detection could be performed by intersecting with an
        incorrect view. In general, the top-most full-screen view is not a
        reliable way to determine the visible portion of the webview.

        This is because when FrameLoader::dispatchDidClearWindowObjectInWorld() is called, the JSWindowProxy for the

        Flaky crash under UserMediaCaptureManagerProxy::SourceProxy::~SourceProxy() on the bots
        https://bugs.webkit.org/show_bug.cgi?id=226653

        Reviewed by Eric Carlson.

        The SourceProxy destructor was taking care of calling invalidate() on the SharedRingBufferStorage
        before destroying the CARingBuffer on the main thread, to avoid having SourceProxy::storageChanged()
        called in the middle of destruction. However, the background thread may still be running at this
        point and may reconstruct the RingBuffer right after the invalidate call, causing us to crash
        because storageChanged() still gets called in the middle on destruction.

        To address the issue, we now make sure to stop the rendering thread before we proceed with the
        destruction and invalidate the SharedRingBufferStorage's storage change handler.

        We have been putting properties to go into the NSURLSessionConfiguration on the _WKWebsiteDataStoreConfiguration.
        This has been ok so far, but now we have an application that needs to run networking attributed to different applications
        but sharing the data storage in the same process.  We now do what we should've done long ago: put these non-storage-related
        properties on the WKWebViewConfiguration.

        I introduce WebPageNetworkParameters which currently has only one member, but will soon have more.

        I made it so that if multiple WKWebViews with the same data store have the same attributedBundleIdendifier, they share an NSURLSession.
        Otherwise, they get their own NSURLSession in a different SessionSet.

        WebIDBServer and before databases are properly closed in some cases, which can caused issues like database is

        The code in [WKShareSheet presentWithParameters] was passing WebCore::RawFile objects to another thread.
        This wasn't safe since WebCore::RawFile contains a WTF::String and a SharedBuffer, both of which are not
        thread safe. Fix this by creating an isolated copy of the fileName String and converting the SharedBuffer
        to a NSData before passing them to the background thread.

        Also rewrite the code from ObjC to C++ because I felt it was clearer and less error-prone.

        Reviewed by Simon Fraser.

        Stop using a RefPtr<IPC::Connection> as HashMap key in DisplayLink. Using a RefPtr as key is suboptimal
        and could leak to memory leaks. The reason this needed a RefPtr<IPC::Connection> was because we needed
        to send IPC from a background thread. To support this, I have added a static IPC::Connection::send()
        function that takes an IPC::Connection::UniqueID and that is thread safe. The function looks up the
        IPC::Connection from its UniqueID and sends the IPC while still holding the lock.

        As a result, DisplayLink can use IPC::Connection::UniqueID as key instead.

        Note that I am planning to use the new static IPC::Connection::send() in other cases where we could
        send IPC directly from a background thread instead of having to hop to the main thread to look up
        the IPC::Connection from its UniqueID. StorageArea::dispatchEvents() is an example of where this will
        be useful.

        https://bugs.webkit.org/show_bug.cgi?id=226104
        <rdar://77998049>

        Reviewed by Eric Carlson.

        In r276993, AudioSessionRoutingArbitration was moved from being initiated in the WebContent process
        and dispatched to the UIProcess, to being dispatched to the GPU process. However two problems occurred:

        1) The UIProcess no longer knows about routing arbitration, which is reasonable for the feature, but
           breaks an API test that queries arbitration status in the UIProcess.

        2) A sandbox violation causes routing arbitration to fail in the GPU process regardless.

        We could open up the sandbox to allow routing arbitration to succeed (and come up with a way to push
        state changes up to the UIProcess for testing purposes), but it's not technically necessary for
        arbitration to occur there. Instead, just revert to the status-quo-ante behavior of having arbitration
        take place in the UIProcess, and just add a new set of messages from the GPUConnoctionToWebProcess to
        the GPUProcessConnection to facilitate arbitration.

        Drive-by fix: AudioSessionRoutingArbitrator is a supplement to WebProcess, and as such it's created
        at WebProcess creation time. However, it also causes an AudioSession to be created by attempting to
        add itself as a client. This is bad on iOS, where it could cause hangs due to AVAudioSession calls.
        So, add a mechanism to be notified when an AudioSession eventually does get created, and add the
        arbitrator as a client then.

        Reviewed by Alex Christensen.

        A while back, we did an optimization to allow several WebPage objects associated with the
        same WebPageProxy to live in the same WebProcess. This allowed us to reuse a process from
        a SuspendedPageProxy for a forward navigation, without destroying the SuspendedPageProxy.
        However, this added quite a bit of complexity and this broke some same-process back/forward
        navigations like in this bug. In particular, it is really hard to get do our history
        management right (with the current model) if there is more than more WebPage in a process
        for the same WebPageProxy.

        To address issues, we go back to the older model with one WebPage per WebProcess for a
        given WebPageProxy. To achieve this, we make sure to destroy of SuspendedPageProxy objects
        for the current page and destination process before we process-swap (like we used to do).

        [GTK] Try harder to find initial WebKitWebView size
        https://bugs.webkit.org/show_bug.cgi?id=226320

        Reviewed by Michael Catanzaro.

        Currently we base the viewport size on the drawing area size. The
        drawing area is created with an initial size based on the viewport
        size, which will be (0, 0) because the drawing area is still null
        by that point.

        Then, later, during the widget allocation, the drawing area receives
        its proper size.

        There are 2 issues here. First, this approach guarantees that the
        initial viewport size will always be (0, 0), and then there's no
        guarantee the widget will be allocated any time soon - for example,
        while GtkNotebook in GTK3 does allocate children that aren't currently
        visible, GtkStack doesn't (and that means that GtkNotebook in GTK4 and
        HdyTabView don't either). This leads to a situation where a page opened
        in background will load with 0, 0 size and if a page depends on that,
        it won't load correctly.

        The first issue can be fixed by basing the viewport size on the view
        allocation as well, and then if the widget isn't allocated, we instead
        try to use the size of a parent as an estimation, so that the initial
        size is at least not 0 even if not fully accurate.

        [iOS] UI process crashes when deallocating WKWebView in a script message handler during an active touch event
        https://bugs.webkit.org/show_bug.cgi?id=226426
        rdar://75425319

        Reviewed by Darin Adler.

        It's possible for the UI process to crash upon being notified that asynchronous, active touch events have been
        handled in the web process via the async IPC replay block in `WebPageProxy::handlePreventableTouchEvent()`. This
        happens if the client posts a message from the web process to UI process while handling an active touch event
        and deallocates the WKWebView currently handling the touch event in the script message handler.

        This is because the async replay block inside `WebPageProxy::handlePreventableTouchEvent()` strongly captures a
        reference to the `WebPageProxy`, thus keeping it alive; however, the `WebPageProxy`'s weak pointer to the page
        client is nulled out, which causes `WebPageProxy::pageClient()` to crash with a null dereference.

        To fix this, we weakly capture `WebPageProxy` instead and return early if it has already been destroyed by the
        time we process the completion handler, and also add a null check for `m_pageClient` before attempting to call
        into it. Note that it's unnecessary to call into `doneDeferringTouch(Start|End)` to unblock any deferred
        gestures here, because the process of destroying the content view will call `-cleanUpInteraction` and remove all
        deferring gestures from the view, regardless of whether they're still in Possible state.

        Drive-by fix: remove a non-templated declaration of `isValidEnum()`. This is necessary in order to use
        `WTF::isValidEnum` without the explicit WTF namespace prefix inside `DisplayListReaderHandle`, since WTF's
        declaration of `isValidEnum` clashes with this declaration.

        Instead of using this separate method for validating the enum, simply encode and decode the
        `shouldOpenExternalURLsPolicy` enum using << and >> operators, respectively; this ensures that the decoded value
        of `shouldOpenExternalURLsPolicy` is either valid, or the result will be WTF::nullopt if decoding fails or
        results in an invalid enum.

        [CoordinatedGraphics] Handle null native surface handle for surfaceless rendering
        https://bugs.webkit.org/show_bug.cgi?id=226165

        Reviewed by Philippe Normand.

        During ThreadedCompositor initialization, a null native surface handle
        would represent a surfaceless rendering target. Assuming corresponding
        driver support for this behavior, the GL context creation would still
        succeed and composition could be performed.

        To support this behavior, the GL context is now spawned first, and if
        successful, the scene is set as active. But in case of a null native
        surface (i.e. surfaceless rendering), the painting has to be mirrored
        by default because of the OpenGL coordinate system being the immediate
        coordinate system inside which we end up working.

        Make CheckedLock the default Lock
        https://bugs.webkit.org/show_bug.cgi?id=226157

        Reviewed by Darin Adler.

        Make CheckedLock the default Lock so that we get more benefits from Clang
        Thread Safety Analysis. Note that CheckedLock 100% relies on the existing
        Lock implementation and merely adds the clang anotations for thread 
        safety.

        That this patch does is:
        1. Rename the Lock class to UncheckedLock
        2. Rename the CheckedLock class to Lock
        3. Rename the Condition class to UncheckedCondition
        4. Rename the CheckedCondition class to Condition
        5. Update the types of certain variables from Lock / Condition to
           UncheckedLock / UncheckedCondition if I got a build failure. Build 
           failures are usually caused by the following facts:
           - Locker<CheckedLock> doesn't subclass AbstractLocker which a lot of
             JSC code passes as argument
           - Locker<CheckedLock> has no move constructor
           - Locker<CheckedLock> cannot be constructed from a lock pointer, only
             a reference

        For now, CheckedLock and CheckedCondition remain as aliases to Lock and 
        Condition, in their respective CheckedLock.h / CheckedCondition.h headers.
        I will drop them in a follow-up to reduce patch size.

        I will also follow-up to try and get rid of as much usage of UncheckedLock
        and UncheckedCondition as possible. I did not try very hard in this patch
        to reduce patch size.

        Convert DestinationColorSpace from an enum to class wrapping a platform color space (CGColorSpaceRef for CG ports, etc.)
        https://bugs.webkit.org/show_bug.cgi?id=226143

        Reviewed by Darin Adler.

        - Update ImageBuffer subclass signatures to use "const DestinationColorSpace&" to
          conform to the base class.
        - Replace ColorSpaceData with Optional<DestinationColorSpace>. No reason to have two
          types that are the same.
        - Give all ports a color space configuration for ShareableBitmap now that there is
          a common class for representing color space.
        - Update DisplayList decoding to account for BeginClipToDrawingCommands and GetPixelBuffer
          no longer being inlineable due to now having non-trivial destructors due to 
          DestinationColorSpace member.

        Make CGColorSpaceRef argument coding match other CF objects and use CGColorSpaceCreateWithPropertyList for fallback
        https://bugs.webkit.org/show_bug.cgi?id=226112

        Reviewed by Darin Adler.

        This is a precursor to some color space type unification. This change:
        
        - Modernizes CF arugment coders to use ArgumentCoder specialization. It also means
          we now support encoding CF types both as plain types and RetainPtr<> types, with
          decoding being kept only supporing RetainPtr<>s, as decoding into non-smart pointer
          is not very useful.
        - Move CGColorSpaceRef coding to ArgumentCodersCF and use CGColorSpaceCopyPropertyList
          and CGColorSpaceCreateWithPropertyList as the fallback coding (if there is no name),
          matching what other libraries on macOS and iOS do.
        - Switch ColorSpaceData to be a struct wrapping an Optional<RetainPtr<CGColorSpaceRef>>
          and use the new shared coding. This will be replaced entirely in subsequent changes
          so I didn't want to change this too much now.

        Allow the network process to load / read dataless files stored in the cloud by allowing
        the process to materialize such files. I initially only allowed the AsyncFileStream
        thread to materialize the dataless files and this was enough to make the file upload
        use cases work. However, I noticed that drag and dropping such file in the Safari URL
        bar would fail loading, which I think is bad user experience. As a result, I have
        decided to allow the materializing at network process level.

        I have verified manually that I can now upload such dataless files via either file
        picker or drag and drop (used https://blueimp.github.io/jQuery-File-Upload/). I have
        also verified that drag and dropping such a file in the Safari URL bar successfuly
        loads that file.

        The GPU Process implementation of gpuProcessCachesDirectory does not recognize that WebKit often runs without
        a container (e.g., as part of a daemon process). In such cases, the GPU process will attempt to create a
        cache directory someplace outside of its sandbox and fail, preventing caching from happening.

        We need to use the same logic we use in the WebContent process to address this use case.

        To avoid making this mistake again, let's consolidate the logic in one method, and use it in the multiple places

        Implement a remote Internal Unit in GPUProcess for audio MediaStreamTrack rendering
        https://bugs.webkit.org/show_bug.cgi?id=225603

        Reviewed by Eric Carlson.

        Implement an InternalUnit by creating a ring buffer that gets written on WebProcess and read on GPUProcess by an audio unit.
        In the previous implementation, each audio track was sent to GPUProcess that was doing the mixing.
        Sending was done by sending IPC message for each audio sample, which was also processing inefficient.

        We are now creating an Audio Unit in GPUProcess and similarly to WebAudio asking WebProcess to render audio in a buffer that will be actually rendered by the audio unit.
        The mixing happens in WebProcess so only one buffer is shared between GPUProcess and WebProcess, and no IPC message is sent for each chunk.

        The potential downside is that the mixing is done with fixed chunk size instead of chunk size requested by the audio unit.
        This might trigger some latency or some overhead if the fixed chunk size is too far from what the audio unit is asking.

        In case of GPUProcess crash, we keep the same format description but we delay recreation of the unit if the unit is stopped.

        It is not safe to call GraphicsContext::paintFrameForMedia() off the main thread because it
        relies on the MediaPlayer / MediaPlayerPrivate objects, which are main-thread object. Making
        this function thread-safe would be a significant amount of work. As a result, I am simply
        calling callOnMainThreadAndWait() in RemoteRenderingBackend::applyMediaItem(). Note that this
        code path is only used when painting a video to a canvas.

        Simplify and make InjectedBundle::initialize() more robust as we are seeing some flaky
        crashes in this area (rdar://33894266).

        In particular, the following changes were made:
        - Call dlopen_preflight() before dlopen() for extra robustness as we see some crashes under dlopen().
        - Call [NSBundle preflightAndReturnError:] before [NSBundle loadAndReturnError:] for extra robustness
          as we see some crashes under [NSBundle loadAndReturnError:].
        - Call [NSBundle loadAndReturnError:] instead of [NSBundle load] so that we get a useful NSError for
          logging.
        - Call [NSBundle initWithPath:] instead of [NSBundle initWithURL:] since we have a path and since
          [NSBundle initWithURL:] ends up calling [NSBundle initWithPath:] anyway. This avoids us having to
          construct a NSURL from our path.
        - Use NSBundle.executablePath instead of CFBundleCopyExecutableURL() since it is nicer and we have
          a NSBundle.
        - Use [NSString fileSystemRepresentation] to gets a file system representation of NSBundle.executablePath.
          Previously, we were relying on CFURLGetFileSystemRepresentation().

        [iOS][FCR] <select multiple> picker should collapse sections when tapping anywhere on a group header

        <rdar://problem/77930033>

        Reviewed by Wenson Hsieh.

        Currently, the <select multiple> picker only collapses a section when
        tapping on the disclosure button on the side of the group header. Instead,
        a tap anywhere on the group header should collapse/expand the corresponding
        section.

        The new behavior is achieved by introducing WKSelectPickerGroupHeaderView,
        a view that encapsulates the header label and disclosure icon. A tap
        gesture recognizer is added to animate the icon, and notify the its
        owner (WKSelectPickerTableViewController) when the view is tapped.

        This patch also corrects the icon animation in RTL layouts, and corrects
        the spacing between the header label and icon.

        We use a lot of SharedMemory-backed CARingBuffers. The pattern is that a process creates the

        for its CARingBuffer. Because the process that sends us the SharedMemory::Handle may not be
        trusted, we need to validate that the size of the storage is sufficient based on the
        CARingBuffer's format & frameCount.

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

        Reviewed by Darin Adler.

        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.

        Allow wheel events to be coalesced during scroll deceleration
        https://bugs.webkit.org/show_bug.cgi?id=225834
        <rdar://70402512>

        Reviewed by Tim Horton.

        When scrolling slows down towards the tail end of a momentum scroll, we can reduce our
        commit frequency to save power, but we only want to do this on displays whose refresh rate
        is higher than the default "update rendering" frequency.

        We do this by leveraging the existing WebWheelEventCoalescer, which coalesces events
        in the UI process. It tracks time since previous event, and coalesces when the
        instantaneous velocity is less than 320 points per second (matching other frameworks
        on the system).

        WebWheelEventCoalescer needs to know when to enable coalescing, which it computes
        on creation, and when the window is moved to a different screen with potentially
        a different refresh rate.

        Javascript can't access a SameSite=Strict cookie after page is loaded after a redirect from a third party site
        https://bugs.webkit.org/show_bug.cgi?id=208049
        <rdar://problem/59701889>

        Reviewed by Chris Dumez.

        The HTTP WG has decided that SameSite=strict cookies should be returned in document.cookie
        even in cases where they are not sent in the HTTP request for the page. Chromium and Gecko
        now work according to those rules and the spec is being updated.

        See:
        - https://github.com/httpwg/http-extensions/issues/769
        - https://github.com/httpwg/http-extensions/pull/1428/files.

        Here's an excerpt from the spec change:
            'If a user agent does return cookies for a given call to a "non-HTTP" API with
            an associated Document, then the user agent MUST compute the cookie-string
            following the algorithm defined in {{retrieval-algorithm}}, indicating that the
            retrieval is from a "non-HTTP" API. The retrieval-uri is the associated
            Document's cookie URL {{COOKIE-URL}}, and the retrieval is same-site if the
            Document's "site for cookies" is same-site with the top-level origin as defined
            in {{document-requests}}.'

        Existing layout tests changed and rebased.

        Reviewed by Jer Noble.

        `TextTrackPrivateRemote::setMode()` calls `InbandTextTrackPrivate::setMode()`, but
        it does not set the value of `TextTrackPrivateRemote::mode` properly. Therefore,
        `TextTrackPrivateRemote::mode` will always be `Disabled`. When we switch text track
        in the WebContent process side, we will only send the IPC message `TextTrackSetMode`
        to `RemoteMediaPlayerProxy` in the GPU process to change the mode from `Disabled`
        to `Showing`, but cannot change its value back to `Disabled`. When a user keeps
        switching text track, all text tracks in the GPU process will become `Showing`,
        and `MediaPlayerPrivateAVFoundation` cannot deal with that. As a result,
        the WebContent process won't get the correct subtitles from the GPU process.
        `cueFormat()` has the similar issue, it does not impact the functionality though.

        Actually, `TextTrackPrivateRemote` can simply use the implementations of its
        base class `InbandTextTrackPrivate` regarding mode and cue format.

        In addition, `TextTrackPrivateRemote` does not need to get the "mode" value from
        `RemoteTextTrackProxy` in the GPU process. So this patch removes the `mode` attribute
        of `TextTrackPrivateRemoteConfiguration`.

        [Cocoa] Silence uninteresting sandbox reports
        https://bugs.webkit.org/show_bug.cgi?id=225713
        <rdar://problem/77483132>

        Reviewed by Per Arne Vollan.

        Telemetry from the recently released iOS and macOS updates show a set of uninteresting sandbox violations. Most of
        these are harmless, but all of them involve some runtime cost and may prevent code from making the best use of
        available hardware and should be permitted.

        These changes also bring the various sandboxes into better alignment, as many of these items had previously been
        added to one of the other sandboxes.

        REGRESSION (r275297): Unexpected autofocus when switching tabs
        https://bugs.webkit.org/show_bug.cgi?id=225710
        <rdar://problem/77542939>

        Reviewed by Wenson Hsieh.

        r275297 introduced logic to handle a focus environment change by
        advancing to the next or previous focusable element, depending on the
        focus context's heading direction. This logic enables a tab or a
        shift+tab to change the focus from browser chrome directly to an
        element on a web page.

        However, the focus environment can change through mechanisms other than
        tab / shift+tab. One example of this is when a user switches tabs. In
        these cases, the UIFocusHeading supplied by the focus context is
        UIFocusHeadingNone. Nevertheless, we unconditionally call
        `-[WKContentView _becomeFirstResponderWithSelectionMovingForward:completionHandler:]`
        when the focus context changes. Consequently, an element on the web page
        is always focused when the WKContentView gains focus.

        * UIProcess/ios/WKContentView.mm:
        (-[WKContentView didUpdateFocusInContext:withAnimationCoordinator:]):

        To fix, ensure we only focus an element on the page if the focus heading
        is UIFocusHeadingNext or UIFocusHeadingPrevious. UIFocusHeadingNext will
        focus the first focusable element, while UIFocusHeadingPrevious will focus
        the last focusable element.

        Note that a call to `-[WKContentView becomeFirstResponder]` is not made
        if the focus heading is UIFocusHeadingNone. From my testing, I observed
        that the view already was the first responder in that case.

        Add SPI to suspend / resume a WKWebView

        <rdar://77462543>

        Reviewed by Geoff Garen.

        Add SPI to suspend / resume a WKWebView. This suspends the page as if it was in
        the back/forward cache but the suspension happens in-place, no need to navigate.
        The suspended page is also not part of the Back/Forward cache so its cap on the
        number of suspended pages does not apply here.

        Most of WKWebView's API / SPI will throw an exception when called on a suspended
        view (The WKPageRefAPI will RELEASE_ASSERT()). Some of the basic API will stay
        functional (URL, isLoading, title, ...). It is also safe to deallocate / close
        a suspended WKWebView.

        [iOS] Mail compose web view doesn't scroll to reveal the selection in certain configurations

        rdar://77095886

        Currently when computing input view bounds upon receiving `UIKeyboardDidChangeFrameNotification`, we attempt to
        map the on-screen bounds of the keyboard to the window's coordinate space, and save the result in an ivar in
        `WKWebView`, `_inputViewBounds`. The keyboard frame (which corresponds to `UIKeyboardFrameEndUserInfoKey` in the
        notification's userInfo dictionary) is given to us in screen coordinates, and we currently pass this through
        `-convertRect:fromWindow:`, with a nil `UIWindow`.

        However, this results in mapping the rect from the coordinate space of the window's `UIWindowScene` rather than
        the window screen. In shipping Mail on iOS, this doesn't matter because the window containing the compose web
        view shares the same coordinate space as the screen. In some other configurations of MobileMail, however, the
        compose web view appears inside its own `UIWindow`. This causes the above coordinate conversion logic to fail,
        since we attempt to map a rect given to us in screen coordinates from the compose web view's window scene's
        coordinate space, instead of the screen's coordinate space.

        We fix this by using `-convertRect:fromCoordinateSpace:` instead, and explicitly pass in
        `self.window.screen.coordinateSpace`.

        Add SPI to suspend / resume a WKWebView
        https://bugs.webkit.org/show_bug.cgi?id=225333
        <rdar://77462543>

        Add SPI to suspend / resume a WKWebView. This suspends the page as if it was in
        the back/forward cache but the suspension happens in-place, no need to navigate.
        The suspended page is also not part of the Back/Forward cache so its cap on the
        number of suspended pages does not apply here.

        Most of WKWebView's API / SPI will throw an exception when called on a suspended
        view (The WKPageRefAPI will RELEASE_ASSERT()). Some of the basic API will stay
        functional (URL, isLoading, title, ...). It is also safe to deallocate / close
        a suspended WKWebView.

        [iOS] Pages with service workers do not suspend promptly
        https://bugs.webkit.org/show_bug.cgi?id=225598

        Reviewed by Youenn Fablet.

        WebProcessProxy::updateServiceWorkerProcessAssertion() was starting a foreground/background activity
        if there is a service worker in-process and if any of the client processes are foreground/background.
        The issue is that a common case is that one of the client process is the service worker process
        itself (since we run the service worker in-process whenever possible nowadays). As a result, it would
        create a process assertion cycle. We'd start a foreground activity due to the service worker but we
        would not release it when the view is no longer foreground, because the process would stay "foreground"
        due to the service worker process assertion.

        To address this, updateServiceWorkerProcessAssertion() now only takes process assertions if there
        are client processes other than the current process. This avoids the cycle and this is really the only
        case we need to make sure the service worker process doesn't suspend. In the case where the service
        worker and the client are in the same process, then the normal process assertions are sufficient.

        [iPadOS] Do not present custom input peripherals when switching back to a tab with a focused element
        https://bugs.webkit.org/show_bug.cgi?id=225541
        <rdar://problem/77537795>

        Reviewed by Wenson Hsieh.

        With the introduction of desktop-class browing on iPad, form control
        elements began to retain focus even after their input peripheral
        (popover, menu, etc.) was dismissed. This behavior matches macOS - when
        a <select> element is clicked, a menu is presented, and when a option
        is selected, the menu is dismissed but the element retains focus.

        Consequently, when a <select> menu is dismissed by choosing an option on
        an iPad with a hardware keyboard, the element retains focus. Now, when
        switching tabs and coming back to the tab with the focused <select>, an
        activity state update is triggered. Upon recognizing that there is a
        focused element, an ElementDidFocus message is sent to the UIProcess.

        In [WKContentView _elementDidFocus:userIsInteracting:blurPreviousNode:activityStateChanges:userObject:],
        the focus is given permission to present the input peripheral (menu)
        when the hardware keyboard is attached. This is necessary when necessary
        when focusing a text input, because the UCB needs to be displayed and
        text selection needs to be set up. However, the behavior is undesirable
        for elements that present a popover or a menu (select, color inputs, and
        date inputs), since the user is unexpectedly shown an input peripheral.
        Even worse, the user's scroll position will be changed to ensure the
        focused element is visible.

        To fix the undesirable behavior, and get closer to the macOS behavior,
        custom input peripherals should not be displayed when switching back
        to a tab with a focused element.

        Use IPC::Semaphore instead of sending an IPC message for every captured audio sample
        https://bugs.webkit.org/show_bug.cgi?id=225452

        Reviewed by Eric Carlson.

        Previously, we were sending an IPC message from UIProcess or GPUProcess to WebProcess for every microphone audio sample chunk.
        We are now using IPC::Semaphore to signal that a new chunk is to be processed.

        We no longer send the chunk timestamp. Instead, we reconstruct it from the number of previously processed samples.
        At audio storage change, we send the start time and we assume that there is continuous timing based on sample counts after that.
        That is why we recreate a new audio storage change anytime we need to reset or the configuration changes, which should not happen often in practice.

        We process fixed-size chunks on WebProcess side and signal it on GPUProcess/UIProcess side.
        This size is sent through IPC at audio storage change time and is the max of 128 samples (WebAudio quantum) and AudioSession preferred size.
        In case WebAudio is used, it should be 128 samples. In case WebAudio is not used, it should be 20 ms of audio data.

        IPC testing API should have the ability to send and receive shared memory
        https://bugs.webkit.org/show_bug.cgi?id=225576

        Reviewed by Wenson Hsieh.

        This patch adds the capability to send & receive shared memory for IPC testing purposes.
        It adds IPC.createSharedMemory which creates a JavaScript object representing a newly
        allocated IPC-sharable memory. It has readBytes and writeBytes methods. Both takes offset
        and the number of bytes to read / write. readBytes will return a new ArrayBuffer and
        writeBytes takes an ArrayBuffer or a typed array as the first argument.

        IPC.sendMessage and IPC.sendSyncMessage now supprts encoding this SharedMemory JavaScript
        object. It supports the type specific arguments of "protection" and "dataSize" in addition
        to the regular "value" property for the SharedMemory object.

        This patch also adds the support for sending Semaphore object over IPC created via
        IPC.createSemaphore, which was supposed to be added in r277199.

        Finally, this patch also exposes the VM page size via IPC.vmPageSize to facilitate
        the allocation of a sharable memory of an interesting size for testing purposes.

        https://bugs.webkit.org/show_bug.cgi?id=225373

        Reviewed by Sam Weinig.

        This patch fixes three problems related to the lifetime of WKURLSchemeTasks:

        1. There was an unneeded abstraction API::URLSchemeTask which wrapped a WebURLSchemeTask, which could have a different lifetime than its owner.
           This is especially bad since at least one was used on multiple threads.
        2. We weren't explicitly keeping a strong reference to the task given to the API client in startURLSchemeTask: and stopURLSchemeTask: which could
           cause all our internal maps to release their references to the task after the first call to didFailWithError and there was a test that did multiple
           calls to didFailWithError and verifies it throws an NSException the second time.
        3. We were keeping a HashSet of raw WebURLSchemeHandler pointers, then using each of them without keeping it alive.

        This is covered by at least the URLSchemeHandler.Exceptions API test which would crash in many exciting places before this but doesn't crash after this.

        We block access to various media things (like 'com.apple.audio.AudioComponentRegistrar') when the GPU Process is being used.
        Some AudioToolbox code continues to try to connect even though we are not activating relevant parts of the audio subsystem.
        AudioToolbox doesn't care about this blocked connection when running in this mode, but they have not had a chance to modify

        [GTK4] Rewrite GTK gesture support to work for both 3.x and 4.x.
        https://bugs.webkit.org/show_bug.cgi?id=212324

        Reviewed by Carlos Garcia Campos.

        Rewrite the touch gesture handling to avoid GdkEvent as an exchange
        token, and not rely on the web view being able to hold and re-route
        these at whim. This makes touch and touchpad gestures work on GTK3
        and GTK4 in similar ways, and so that both work.

        For this, touch event propagation got some substantial changes, it
        used to work by first delivering the touch events to the web page,
        and manually feeding the returned+unhandled ones to gesture controllers.
        Now event delivery is delegated on GTK, and happens right away on
        gesture controllers, it is the WebkitWebViewBase which chooses to make
        them effective after the web page (maybe) handled the events. Gestures
        are reset whenever the web page is considered to be handling touch
        events.

        Also fix some buglets accumulated along the way, web view zoom conflicted
        with in-page zoom handling, and ViewGestureController page switching
        conflicted with press-drag-release emulation on the web page. These now
        work better and closer to GtkScrolledWindow behavior.

        No new tests, the GTK touch tests that should catch this were disabled
        in the past and need fixing. This patch will require manual testing.

        [iOS] Safari sometimes hangs underneath `WebKit::UIDelegate::UIClient::createNewPage`

        rdar://77565282

        Consider the scenario where a webpage programmatically opens a window in a new tab on iOS while the keyboard is
        visible. In certain configurations, Safari indirectly tells the `WKWebView` containing the original webpage to
        `-resignFirstResponder` and then `-becomeFirstResponder` again, while creating a new web view and shuffling
        around the view hierarchy under `-webView:createWebViewWithConfiguration:forNavigationAction:windowFeatures:`.

        Since the keyboard is up, this causes UIKit to ask for an autocorrection context via `-[WKContentView
        requestAutocorrectionContextWithCompletionHandler:]`, which blocks the main thread on a response from the web
        process. Of course, since we're handling synchronous IPC, the web process isn't capable of sending a response
        back to the UI process, so we deadlock until we exceed the IPC timeout, and then exit the call stack.

        Instead, it's possible in this case to recognize that we're already handling a synchronous IPC message, and any
        attempts to wait for a response will time out anyways. Instead of waiting for the entire timeout duration, we
        can fail eagerly to avoid hanging the process that is waiting.

        we have a non-infinite IPC timeout duration, then we should fail sooner inside `Connection::waitForMessage`,
        instead of waiting to time out.

        Drive-by refactoring: while we're here, let's also move initialization for some of the members on `Connection`
        into the class declaration, instead of the constructor.

        When the MediaPlayerPrivate supports the new "current time changed" callback, use it

        changes much more frequently than the other state that needs to be pushed to the

        and push it separately when it changes, which also allow us to reduce the polling
        frequency significantly.

        Some of the state we were updating every time the cached state timer fired only

        [iOS] UI process hangs when showing a modal JavaScript dialog while focusing an input field
        https://bugs.webkit.org/show_bug.cgi?id=225409
        rdar://76792407

        Reviewed by Darin Adler, Chris Dumez and Tim Horton.

        Consider the scenario where an input field has a focus event handler that shows a modal JavaScript dialog (e.g.
        confirm, alert, prompt). We get the following sequence of events in this scenario:

        (WEB)   The text field is focused, and sends WebPageProxy::ElementDidFocus. A modal dialog is then triggered by
                script inside the focus event handler, sending a message like WebPageProxy::RunJavaScriptAlert.

        (UI)    The UI process receives WebPageProxy::ElementDidFocus, and calls `-reloadInputViews` while showing the
                keyboard. UIKit may then call back into `-requestAutocorrectionContextWithCompletionHandler:`, which
                triggers sync IPC back to the web process. While waiting to receive a response message, we receive and
                dispatch WebPageProxy::RunJavaScriptAlert.

        At this point, the UI process is still waiting for a HandleAutocorrectionContext response IPC message, but the
        web process is blocked on a response to the modal JavaScript dialog; since both processes are blocked on each
        other, we're now in deadlock.

        To mitigate this, we can preemptively send autocorrection context data right before we're about to synchronously
        block in the web process on a modal dialog. In the UI process, we use this autocorrection context object to
        immediately stop syncwaiting for a HandleAutocorrectionContext response. See below for more details.

        Make a slight adjustment here so that `waitForMessage` bails if one of the messages we're dispatching underneath
        `SyncMessageState::dispatchMessages` is the message we happen to be waiting for anyways. In this case, it's
        necessary in order for the preemptive `WebPageProxy::HandleAutocorrectionContext` message sent by the web
        process to unblock the UI process, which is waiting for a `WebPageProxy::HandleAutocorrectionContext` response.

        Avoid blocking on the web process if it's waiting on a modal JavaScript dialog anyways; just use the last
        autocorrection context we received from the web process (which we know must've been sent right before showing
        the modal dialog anyways).

        (-[WKContentView runModalJavaScriptDialog:]):

        In the case where we're in the process of presenting the keyboard (or UCB) on iOS after focusing an input field,
        avoid immediately allowing the client to show any modal UI until we're done managing keyboard logic in WebKit.
        Without this adjustment, we'll end up trying to present the modal JavaScript dialog in the middle of UIKit's
        call to `-requestAutocorrectionContextWithCompletionHandler:`, which then causes UIKit to throw an exception
        underneath keyboard code.

        Sampled Page Top Color: take additional snapshots further down the page to see if the sampled top color is more than just a tiny strip
        https://bugs.webkit.org/show_bug.cgi?id=225323

        Reviewed by Beth Dakin.

        Add a `SampledPageTopColorMinHeight` setting that controls how far down the sampled page top
        color needs to extend in order for us to not bail. If the value > 0, we take an additional
        snapshot at (0, SampledPageTopColorMinHeight) and (width, SampledPageTopColorMinHeight),
        comparing each to the snapshot directly above (e.g. (0, SampledPageTopColorMinHeight) is
        compared to (0, 0)) using the `SampledPageTopColorMaxDifference`. Depending on the value, if
        the color across the top of the page is only a small strip, these extra snapshot comparisons
        will prevent a resulting color from being derived.

        When enabling/disabling a track, the web content process would send a message to the GPU process which in turn
        would send a message back to the content process, notifying that the track configuration had changed, that would
        then enable/disable again the track.
        If the content process in between those IPC messages had modified the track (such as via JS call), it was
        possible for the track status to get lost once the GPU message above got actioned.

        Having the GPU process notify that a track configuration got changed when it was originally triggered by the
        content process is unnecessary. We modify the RemoteAudioTrack and RemoteVideoTrack so that if the change came
        from the web process, the GPU process doesn't send a message back with information that could already be obsolete.

        Reviewed by Brady Eidson.

        When we switched from using _pageGroup to _groupIdentifier, we also broke localStorage by making a new pageGroupID for each WKWebView.
        This is the low-risk solution to this problem that remembers what pageGroupID we used for this same identifier, creating the effect of
        using the same StorageNamespaceIdentifier for each _groupIdentifier like we did when we used _pageGroup.
        See the comment in StorageAreaMap::dispatchLocalStorageEvent.

        The higher-risk solution that needs to be done but probably shouldn't be merged to a branch at this point is to remove StorageNamespaceIdentifier.
        I plan to do that in a follow-up patch.

        Currently, <select> options within an <optgroup> element are presented
        within an expandable/collapsible submenu. However, to better match the
        visual style across the rest of the system, the grouped options should
        appear inline in the root menu, and groups should be separated by a
        visual separator.

        Removed logic to promote the grouped submenu to the root menu in the

        [macCatalyst] "Enter Full Screen" button in media controls disappears

        Reviewed by Eric Carlson.

        In order for the "Enter Full Screen" media controls button to stay visible the `<video>`
        must return `true` for `HTMLMediaElement::webkitSupportsFullscreen`, which calls into
       `MediaPlayerPrivate::supportsFullscreen`. On macOS and iOS, this will always return `true`
        because of `ENABLE(FULLSCREEN_API)`, but on macCatalyst that's not enabled, so we instead
        use `DeprecatedGlobalSettings::avKitEnabled`, but this is only set in the WebProcess (and
        WK1). With the GPUProcess enabled, this value is not set, so the `RemoteMediaPlayerProxy`
        will instead get `false`.

        This patch removes `DeprecatedGlobalSettings::avKitEnabled` since it's enabled on WK1 and
        non-GPUProcess WK2, and the related iOS-only SPI appears to not be used anywhere internally,
        instead having callsites just check `HAVE(AVKIT)`.

        [iOS] Crash when tapping fields on cycle.travel
        https://bugs.webkit.org/show_bug.cgi?id=225259
        <rdar://problem/77386417>

        Reviewed by Wenson Hsieh.

        The From/To fields on cycle.travel have a click handler that presents
        a popover. The popover is presented by changing its display property
        from "none" to "block", and contains an input element with the "autofocus"
        attribute. After changing the popover element's display property, the
        page focuses another element by calling focus().

        In WebKit, focusing an element sends an IPC message from the WebProcess
        to the UIProcess, so that UIProcess knows of the focused element and
        can present the necessary UI. All relevant information about the element
        is encoded in a FocusedElementInformation struct, which is populated by
        WebPage::getFocusedElementInformation.

        Prior to populating the FocusedElementInformation,
        getFocusedElementInformation performs a layout if needed,
        so that the information sent to the UIProcess is up-to-date. In this
        instance, a layout is needed after the popover element's display
        property is changed. Then, since the page immediately focuses another
        element after the display change, WebKit calls
        getFocusedElementInformation prior to the layout being performed.
        getFocusedElementInformation then sees that a layout is needed, and
        triggers the pending layout.

        Now, since since the popover contains an element with "autofocus",
        another element is focused as a post-layout task. This means that the
        layout triggered by getFocusedElementInformation changes the focused
        element. r256401 added an early return in this case, to prevent a null
        pointer deref.

        An early return in getFocusedElementInformation leaves the passed-in
        FocusedElementInformation in an inconsistent state. In particular,
        the FocusedElementInformation's elementContext is left with invalid
        identifiers. Currently, all callers of getFocusedElementInformation do
        not check whether the information is in a valid state. Consequently,
        the caller (in this case, WebPage::elementDidFocus) proceeds to send
        an IPC message with the FocusedElementInformation as one of the
        arguments. Then, a release assert is hit as sending IPC messages with
        invalid arguments is unsafe.

        To fix, make getFocusedElementInformation return an optional
        FocusedElementInformation, rather than populating a parameter that
        could be left in an invalid state. Then, any early returns can return
        WTF::nullopt, to signify that we were unable to generate a valid
        FocusedElementInformation. Finally, whenever the method returns
        nullopt, we do not send the IPC message (or in another case, send a
        message with nullopt).

        [iOS] Add a heuristic to determine whether a synthetic click triggered any meaningful changes
        https://bugs.webkit.org/show_bug.cgi?id=225240
        rdar://77221196

        Reviewed by Tim Horton.

        Add a simple heuristic to inform WKWebView iOS clients when a tap either failed to result in a synthetic click,
        or resulted in a synthetic click that (probably) didn't have any "meaningful side effects". While this notion of
        "meaningfulness" isn't well defined, the idea behind the heuristic is that it should distinguish between taps on
        clickable elements like buttons or links that trigger some noticable change on the page, vs. taps on both
        clickable or non-clickable elements that do not trigger any changes on the page.

        For instance on a news-article-like page, this delegate method should be invoked when tapping on paragraph text
        in the article, even if there is a click handler over the entire article or even body element. However, tapping
        a link or a button on the same page should not cause this delegate method to be invoked. Additionally, if the
        page explicitly prevents default behavior during a synthetic mouse event, this method should also *not* be
        invoked.

        This behavior is roughly similar to the existing delegate method `-_webView:didNotHandleTapAsClickAtPoint:`,
        except that this variant allows for more wiggle room around what constitutes a "meaningful" interaction with the
        page.

        Always pass the cache directory for HTTP/3 use, regardless of the current setting of
        the flag. We still pass the flag so that users can turn the feature on and off, so there
        is no change in expected behavior. However, certain OS settings can override the user
        setting in the browser, so it's helpful to have the path permission for cases where a user

        [GPUP] Two message loops between WebContent process and GPU process to enable/select audio/video tracks
        https://bugs.webkit.org/show_bug.cgi?id=225193

        Reviewed by Eric Carlson.

        The current implementation has two message loops between Web process
        and GPU process related to enable/select audio/video tracks.

        For audio, the message loop is:
        Web Process -> GPU process: RemoteMediaPlayerProxy::audioTrackSetEnabled
        GPU Process -> Web Process: MediaPlayerPrivateRemote::remoteAudioTrackConfigurationChanged

        The message loop will lead to the following function call loop:

        AudioTrackPrivateRemote::updateConfiguration()
        AudioTrackPrivateRemote::setEnabled()
        RemoteMediaPlayerProxy::audioTrackSetEnabled()
        RemoteAudioTrackProxy::setEnabled()
        AudioTrackPrivateAVFObjC::setEnabled()
        AudioTrackPrivate::setEnabled()
        RemoteAudioTrackProxy::enabledChanged()
        RemoteAudioTrackProxy::configurationChanged()
        MediaPlayerPrivateRemote::remoteAudioTrackConfigurationChanged()
        again, AudioTrackPrivateRemote::updateConfiguration(), and repeat ...

        The loop for video tracks is similar.

        The loop is bad but normally does not impact a media player's functionality.

        However, if a page disables and enables an audio track of a media element with HLS stream
        in one run loop, the loop will disable and enable the track repeatedly, as a result,
        CoreMedia's HLS player will disable/enable audio segments and send/cancel download
        requests repeatedly. Eventually the player won't play audio.

        This patch fixes these two message loops.

        Reduce memory footprint for background tabs
        https://bugs.webkit.org/show_bug.cgi?id=225007

        Reviewed by Chris Dumez.

        When a WebContent process contains only non-visible pages (e.g. if it is a background tab),
        we should attempt to reduce our memory footprint after some time interval to help relieve
        system-wide memory pressure. This is enabled only on Mac because iOS already does something
        similar just before WebContent suspends.

        One exception to this is that we don't do this proactive slimming for processes that are in
        the back/forward cache or in the WebProcess cache. This is because dropping the memory cache
        in those types of processes leads to perf regressions in benchmarks that do certain types of
        cross-origin navigations. We'll use a separate mechanism for controlling the memory usage of
        those processes; our current logic keeps those processes around until we are at the warning
        or critical memory pressure level.

        The fix for this crash that I landed in r276688 was based on a misunderstanding that accessing `treeScope()`
        would trigger a null pointer deref if `isInTreeScope()` is `false`. This is not the case, since the `treeScope`
        of a `Node` is a separate notion from whether that `Node` is connected to said tree scope.

        Since this crash is really due to dereferencing a null container node in the case where `selectionStart` or
        `selectionEnd` are null, a better fix is to just check the nullity of the container node.

        [iOS] [GPU] The UI process should issue mach sandbox extensions to 'iconservices'

        In Bug 205443 we did work to extend access to non-web-browsing services to the WebContent process only when
        needed. This was lost in the transition to the GPU Process, and should be added back.

        This change does the following:
        1. Adds sandbox extension handles for the iconservices (and related) services to the GPU process creation parameters.
        2. Updates the GPUProcessProxy to extend iconservices when waranted, and add them to the creation parameter structure.
        3. Updates the GPUProcess to consume the extensions (when granted).
        4. Makes a GPU process-specific version of the 'nonBrowserServices' static function for use by GPUProcessProxy. This is needed
           because fewer services are needed in the GPU process than in the WebContent process.
        5. Removes unused telemetry from the WebContent process sandbox.
        6. Switches the GPU process sandbox to deny iconservices (and related) by default, and to consume the extensions instead.

        Tested by exisiting TestWebKitAPI tests.

        The crash would happen when replyToPendingMessages() get called in the AuxiliaryProcessProxy
        destructor and there would be a pending getGPUProcessConnection() IPC. The lambda in
        WebProcessPool::getGPUProcessConnection() would check if a WeakPtr to the WebProcessPool is
        valid before calling `ensureGPUProcess().getGPUProcessConnection()`. However, at this point, 
        the WebProcessPool destructor is still running so the WeakPtr is still valid but 
        `ensureGPUProcess().getGPUProcessConnection()` will crash because the GPUProcessProxy
        destructor has already run.

        Don't keep local storage data in memory in the NetworkProcess
        https://bugs.webkit.org/show_bug.cgi?id=225065

        Reviewed by Alex Christensen.

        When a WebPage would start to use the local storage API, the WebProcess
        would send a sync IPC to the NetworkProcess to retrieve all the local
        storage entries for the origin. The NetworkProcess would read those
        entries from a SQLite database and send them back to the WebProcess.
        Both the NetworkProcess would keep the entries in memory, in a
        StorageMap object (which is basically a HashMap). On some sites, the
        strings in the local storage may be very large. It is useful for the
        WebProcess to keep them in memory for performance reasons, especially
        considering that the Web API is synchronous. However, there is no real
        need to keep them in memory in the Network Process side, especially
        given that the WebProcess already has its own copy. On the network
        process side, we can get rid of the StorageMap entirely in the local
        storage case and 100% rely on the SQLite database. This is what this
        patch implements.

        A/B testing shows this is a 2-3% progression on Membuster. There does
        not appear to be a meaningful progression on PLUM sadly. This is also

        lost in the transition to the GPU Process and should be added back.

        This change does the following:
        1. Adds sandbox extension handles for the AGX-related compiler services and IOKit classes to the GPUProcess creation parameters.

        5. Moves the 'agxCompilerClasses' and 'agxCompilerServices' functions to WebCore, alongside the other AGX functions.

        It also corrects the sandbox rule for the AGXCompilerService in the GPU Process sandbox, which incorrectly called it a 'global-name',
        when it is an xpc-service.

        We've found that in some workloads, the critical-level memory pressure handler releases
        significantly more memory than the warning-level memory pressure handler. On Macs, it is
        likely that the memory pressure coincides with swapping. So when we get even a warning-level
        notification from the OS, we should err on the side of releasing more memory to help relieve
        the swapping state. To do this, treat warning level notifications the same as critical level
        notifications on Mac if the WebProcess is in the background.

        To fix, include HitTestRequest::IgnoreClipping in the hit test request

        <rdar://76652073>

        Reviewed by Eric Carlson.

        When the WebContent process asks the GPU Process to set the AVAudioSession audio session
        category, the GPU Process as an optimization returns early if the session category being
        requested is the same as has already been set. However, the default value of the category
        is "None" (which translates to AVAudioSessionCategoryAmbient), and setting the category
        to "None" becomes a no-op due to this default. As such, the GPUP never sets the underlying
        AVAudioSession's category away from the default, which is AVAudioSessionCategorySoloAmbient,
        and thus will interrupt other audio during playback.

        Additionally, there's a subtle logic error where the audio session category is not changed
        when a given WebContent process (and it's RemoteAudioSession & Proxy) goes away.

        The fix for both of these issues is to re-calculate the correct audio session category
        when a RemoteAudioSessionProxy is added or removed from RemoteAudioSessionProxyManager.
        Since "None" is the default value for a RemoteAudioSessionProxy, the mere act of adding
        a new RemoteAudioSessionProxy (which is created when a WebContent process is created)
        will cause the audio session category to be set to AVAudioSessionCategoryAmbient.

        [Cocoa] re-enable test case WKInspectorDelegate.InspectorConfiguration
        https://bugs.webkit.org/show_bug.cgi?id=224577
        <rdar://70505272>

        Reviewed by Devin Rousso.

        For the purposes of testing, we want to be able to issue a fetch() that will
        hit a custom URL scheme handler registered with _WKInspectorConfiguration.
        This is not allowed by the existing <meta> tag CSP directive list because 'connect-src *'
        does not allow connecting to arbitrary schemes, just arbitrary domains.

        To fix this, relax the 'connect-src' directive in Main.html and apply
        a dynamically-computed CSP directive using the 'Content-Security-Policy' HTTP
        response header. This is only sent for main resources (Main.html and Test.html)
        using the newly added inspector-resource: URL scheme handler.

        The dynamically computed directive explicitly allows 'self' and any other registered
        custom URL scheme handlers. WebKit ports which have not migrated away from file:///
        will only apply the weaker 'connect-src' directive from the <meta> tag after this change.

        Progresses an existing API test: WKInspectorDelegate.InspectorConfiguration.

        Adjust the presentation rect when showing the Look Up text service popup using the callout bar on iOS so that
        we use the entire bounds of the selection. Currently, we only use the first selection rect (top to bottom) as
        the presentation rect, which may cause the popup to obscure selected text.

        This seems to have been derived from iOS legacy web view behavior that dating back to rdar://7475904; while the
        exact reasoning for this is effectively lost to time, it's likely due to how there used to only be a single
        block selection rect in non-editable content in iOS 5 anyways, so taking only the first selection rect would not
        be incorrect. However, we now use character granularity selection everywhere in WebKit2, so this logic is no

        yet. This is also more consistent with what we do for LegacyCDM since Bug 224905.

        The MediaKeys API still seems functional after r275887 (unlike the LegacyCDM one) so it does
        not seem it caused obvious breakage. That said, it is still safer to restore pre-r275887
        behavior. There is also no drawback to restoring the previous behavior since I made sure the

        Move legacyCDMFactory() getter from GPUProcessConnection to WebProcess so that

        call legacyCDMFactory().registerFactory() inside of WebProcess::setUseGPUProcessForMedia()
        (like before r275887) instead of doing it in the GPUProcessConnection constructor.

        As a result, calls to WebKitMediaKeys.isTypeSupported() return accurate results
        even if the GPUProcess is not launched yet. Calling WebKitMediaKeys.isTypeSupported() ends

        Currently, WKMouseGestureRecognizer just runs with that as a normal

        If an idle GPUProcess doesn't exit under memory pressure because it just launched, check again later
        https://bugs.webkit.org/show_bug.cgi?id=224829

        Reviewed by Darin Adler.

        In r276305, I made it so that the GPUProcess does not exit under memory pressure when idle
        if it launched less than 5 seconds ago. This gives the WebProcess time to schedule work with
        the GPUProcess after launching it and makes sure we don't repeatedly / frequently exit &
        relaunch the GPUProcess.

        In this patch, I am tweaking the policy so that if we could have exited but didn't because
        the GPUProcess was too young (less than 5 seconds old), then I schedule a timer for this
        5 second deadline to check again if the GPUProcess could exit (meaning that it is unused).
        When the timer fires, the process doesn't have to be under memory pressure still in order
        to exit, it just needs to be idle. I figured the fact that we were under memory pressure
        less than 5 seconds ago should be enough incentive to exit if idle.

        Adding the WTF dependency is a bit odd since this would staticly link

        GPUProcess.WebProcessTerminationAfterTooManyGPUProcessCrashes is intentionally repeatedly

        a relaunch and the RemoteAudioDestinationManager::StartAudioDestination synchronous IPC
        may fail if it is ongoing at the time of the crash. This would cause m_destinationID to
        not get initialized and then get sent as IPC parameter, thus crashing.

        pre-r276189, we were not crashing because m_destinationID was not reset on crash and we
        would thus send IPC for a destination that does not exist but at least the destinationID
        would not be 0. This patch makes sure we don't try and send IPC at all when m_destinationID
        is 0.

        MotionMark's Canvas-Arcs subtest is broken if the GPUProcess is not yet running
        https://bugs.webkit.org/show_bug.cgi?id=224778

        Reviewed by Simon Fraser.

        I recently made changes so that the GPUProcess is only launched when it is needed. This means
        that until MotionMark's Canvas-Arcs subtest, the GPUProcess is usually not yet running. As a
        result, RemoteRenderingBackendProxy::createImageBuffer() ends up launching the GPUProcess
        and sending the GPUConnectionToWebProcess::CreateRenderingBackend and
        RemoteRenderingBackend::CreateImageBuffer IPC right away. We seem to have a synchronization
        issue because when this happens, the rendering for the Canvas-Arcs subtest is visibly broken
        and its score is very low (< 6, instead of > 600).

        Making the GPUConnectionToWebProcess::CreateRenderingBackend synchronous again (I made it
        async recently) seems to address the synchronization issue and restores correct behavior on
        MotionMark. I am therefore making this IPC synchronous again in this patch to get benchmark
        coverage again while I investigate the root cause offline.

        Update LibWebRTCCodecsProxy to use a Lock

        Reviewed by Darin Adler.

        Update LibWebRTCCodecsProxy to use a Lock, instead of a std::atomic<bool> that
        has to be kept up to date. I think this simplifies the code a bit. Adding / Removing
        encoder / decoder is not very hot code as far as I know and there will very rarely
        be contention since allowsExitUnderMemoryPressure() is only called on memory pressure.

        m_encoder / m_decoder are still always modified from the background thread. However, we
        now check from the main thread if they are empty by locking.

        Reviewed by Ryosuke Niwa.

        The `blobURL` member of `PromisedAttachmentInfo` was originally introduced to facilitate drag and drop support
        for attachment elements in WebKit2, by writing blob URL data to temporary file paths on behalf of
        `NSFilePromiseProvider` when starting a drag on attachment elements backed by blobs. However, this was
        superceded by use of `NSFileWrapper` and the `_WKAttachment` SPI instead, such that we only support dragging
        attachment elements if they correspond to API `Attachment` objects in the UI process. This means we can remove
        this `blobURL`, along with the file name and content type members of the struct (which were only added to
        support the ability to drag blob-backed attachments).

        LibWebRTCCodecs eagerly launches the GPUProcess and always relaunches it on exit. The GPUProcess
        should only be (re-)launched when needed. In the case of the LibWebRTCCodecs, it seems it only
        needs a GPUProcess connection if it has m_decoders / m_encoders are non-empty.

        Version of dispatchToThread() which makes sure that the GPUProcessConnection is initialized

        (and that we should re-initiate it in case it is severed). If the connection is already
        initialized, then it does a simple dispatchToThread(). If the connection is not initialized

        GPUProcessConnection.

        (WebKit::LibWebRTCCodecs::gpuProcessConnectionMayNoLongerBeNeeded):
        Function that gets called on the background thread every time a encoder / decoder is
        removed. Its purpose is to set m_needsGPUProcessConnection back to false once we no
        longer have any encoder / decoder, so that gpuProcessConnectionDidClose() does not
        attempt to relaunch the GPUProcess if it goes away.

        LibWebRTCCodecs::setCallbacks():
        Check if VP9Support is enabled via PlatformMediaSessionManager instead of from the
        GPUProcessConnection. This avoids eagerly launching the GPUProcess. The
        GPUProcessConnection constructor gets its VPx support information from
        PlatformMediaSessionManager anyway. The WebPage constructor is where the VPx support
        information comes from and it updates the VPx flags on the PlatformMediaSessionManager.
        The WebPage constructor only updates the VPx flags on the GPUProcessConnection if this
        connection already exists to avoid eagerly launching the GPUProcess.

        - Only re-initiate the GPUProcess connection if m_needsGPUProcessConnection is true,
          meaning that we have encoders/decoders. I use this flag instead of checking m_encoders

        Reviewed by Eric Carlson.

        When the connection between the GPUProcess and the WebProcess was severed,
        GPUConnectionToWebProcess::didClose() would get called and end up destroying
        the RemoteAudioDestination object on the main thread. The issue is that the
        RemoteAudioDestination may be playing at the time and we would end up
        destroying the RemoteAudioDestination object without stopping rendering
        first. As a result, we would crash on the background thread in the
        RemoteAudioDestination::render() function, trying to use the m_ringBuffer
        data member that got destroyed on the main thread.

        To address this, I updated the RemoteAudioDestination destructor so that it
        stops rendering if necessary. AudioOutputUnitStop() is synchronous so this
        ensures render() is done running on the background thread (and won't be
        called again) before proceeding with the destruction of the data members.

        - Similarly, drop the check for m_isPlaying. m_isPlaying is not atomic so the check

        Early IPC messages to a WorkQueueMessageReceiver may get processed out of order
        https://bugs.webkit.org/show_bug.cgi?id=224623

        Reviewed by Geoffrey Garen.

        Bug 224566 exposed an issue where early IPC being sent to WorkQueueMessageReceiver might get received
        out of order. The reason behind it is that the WorkQueueMessageReceiver registers itself on the main
        thread while we receive the IPC on the IPC thread. When we receive the IPC on the IPC thread, we check
        if there is a WorkQueueMessageReceiver for it and if there is, we dispatch the message straight to its
        WorkQueue. However, if the WorkQueueMessageReceiver has not registered itself yet on the main thread,
        we hop to the main thread first, before dispatching the IPC back to the receiver's WorkQueue. The
        extra hop to the main thread means that 2 IPC messages to the WorkQueueMessageReceiver sent one after
        the other may get dispatched on the WorkQueue in an inconsistent order, if the WorkQueueMessageReceiver
        registers itself as a receiver in between the 2 IPC messages.

        We actually were trying to deal with this issue in Connection::addWorkQueueMessageReceiver(). When
        the WorkQueueMessageReceiver would register itself on the main thread, we would grab the incomingMessages
        lock and check m_incomingMessages for messages that should be dispatched to the WorkQueue. Those are
        async messages that should have been dispatched straight to the WorkQueue on the IPC thread but didn't
        because the WorkQueueMessageReceiver has not registered itself yet.

        However, this logic in Connection::addWorkQueueMessageReceiver() was insufficient because it only checked
        m_incomingMessages. m_incomingMessages only contains async messages. Sync messages (and special async
        messages with the IPC::SendOption::DispatchMessageEvenWhenWaitingForSyncReply flag) are stored in
        Connection::SyncMessageState::m_messagesToDispatchWhileWaitingForSyncReply. This is what was causing
        Bug 224566 since RemoteRenderingBackendProxy's CreateImageBuffer IPC was async with the
        DispatchMessageEvenWhenWaitingForSyncReply flag and its GetDataURLForImageBuffer was synchronous. The
        ordering of these 2 IPC messages could get reversed and it would cause correctness issues and flaky
        crashes.

        To address the issue, I updated Connection::addWorkQueueMessageReceiver() to ask the
        Connection::SyncMessageState to enqueue its matching messages to the WorkQueue. There was one issue
        though because Connection::SyncMessageState::dispatchMessagesAndResetDidScheduleDispatchMessagesForConnection()
        was taking messages out of m_messagesToDispatchWhileWaitingForSyncReply and storing them in a local
        container and then iterating over this container to dispatch the messages. The dispatching of one
        of these messages could cause a WorkQueueMessageReceiver to register itself (call addWorkQueueMessageReceiver()).
        When this would happen, addWorkQueueMessageReceiver() would try and enqueue matching messages in
        m_messagesToDispatchWhileWaitingForSyncReply and would miss the messages in the local container
        that dispatchMessagesAndResetDidScheduleDispatchMessagesForConnection() is currently iterating on.
        To address this issue, I introduced a new m_messagesBeingDispatched data member and used that to
        store the messages being dispatched instead of the local container. As a result,
        addWorkQueueMessageReceiver() can now enqueue the messages in m_messagesBeingDispatched first and
        then enqueue the ones in m_messagesToDispatchWhileWaitingForSyncReply.

        Revert r276007 that was committed as a temporary workaround for this bug.

        * Platform/IPC/Connection.cpp:
        (IPC::Connection::SyncMessageState::enqueueMatchingMessages):
        Add utility function to SyncMessageState to enqueue its matching messages in m_messagesBeingDispatched
        and m_messagesToDispatchWhileWaitingForSyncReply to the provided MessageReceiveQueue. This is called
        by Connection::addMessageReceiveQueue(). The logic is similar to the one in the
        enqueueMatchingMessagesToMessageReceiveQueue() function but works on a Deque<ConnectionAndIncomingMessage>
        instead of a Deque<std::unique_ptr<Decoder>>.

        (IPC::Connection::SyncMessageState::dispatchMessages):
        (IPC::Connection::SyncMessageState::dispatchMessagesAndResetDidScheduleDispatchMessagesForConnection):
        Use m_messagesBeingDispatched instead of a local container to store the messages we are about to
        dispatch. This allows enqueueMatchingMessages() to check those messages to see if they should be
        dispatched to a MessageReceiveQueue. We also need to make sure we don't iterate over
        m_messagesBeingDispatched to call dispatch() on the messages. This is important because any message
        dispatch may cause a WorkQueueMessageReceiver to register itself, which would call
        enqueueMatchingMessages() and potentially extract matching messages from m_messagesBeingDispatched.
        For this reason, we take messages from m_messagesBeingDispatched one by one, until the container
        becomes empty.

        (IPC::Connection::addMessageReceiveQueue):
        (IPC::Connection::addWorkQueueMessageReceiver):
        (IPC::Connection::addThreadMessageReceiver):
        - This used to only check m_incomingMessages for matching messages that should be enqueued on the
          MessageReceiveQueue in order to preserve IPC ordering. This was insufficient because it would fail
          to consider sync IPC messages (or async IPC messages with the
          IPC::SendOption::DispatchMessageEvenWhenWaitingForSyncReply flag). Since those are stored in separate
          containers in Connection::SyncMessageState, we now also call
          Connection::SyncMessageState::enqueueMatchingMessages() to enqueue those messages and preserve their
          ordering too. This fixes IPC ordering bug identified via Bug 224566.
        - Avoid some code duplication by moving more logic to a shared enqueueMatchingMessagesToMessageReceiveQueue()
          function. The function is no longer templated because I don't think it is worth increasing binary
          size just to avoid the virtual enqueueMessage() function call on the MessageReceiverQueue. We do not
          register message receivers very often and then only have a few early messages at most to enqueue.

        Remove the ability for clients to influence `-[WKContentView canBecomeFocused]` by overriding `-[WKWebView
        canBecomeFocused]`. Apparently, making `WKWebView` focusable by UIKit in addition to the content view causes the
        web view to occasionally take first responder instead of the content view, which then breaks key event handling.

        Instead, make it so that `-[WKContentView canBecomeFocused]` still returns `NO` by default, return `YES` for
        internal clients that override the private UI delegate method `-_webView:takeFocus:`, and additionally introduce
        a new delegate method, `-_webViewCanBecomeFocused:`, so that clients can make `-[WKContentView canBecomeFocused]`
        return `NO` even if the delegate responds to `-_webView:takeFocus:`. This is because it doesn't make sense for a
        WebKit client to allow UIKit's focus engine to (effectively) descend into web content without a way for the
        embedder to handle the case where focus later ascends out of web content (and asks the UI delegate to take
        focus).

        REGRESSION(r275921-r275922): [ wk2 ] http/tests/security/webgl-remote-read-remote-image-allowed-with-credentials.html is flakey crashing
        https://bugs.webkit.org/show_bug.cgi?id=224566
        <rdar://problem/76657007>

        Reviewed by Tim Horton.

        r275921-r275922 changed the timing of when the WebProcess/RemoteRenderingBackendProxy sends the GPUConnectionToWebProcess::CreateRenderingBackend
        IPC to the GPUProcess. This IPC used to get sent as soon as the RemoteRenderingBackendProxy was constructed. However, I delayed sending it until
        the RemoteRenderingBackendProxy actually needs to create an ImageBuffer to avoid launching the GPUProcess prematurely.

        Unfortunately, this exposed a pre-existing synchronization issue with regards to the RemoteRenderingBackend IPC. In particular, the
        GPUConnectionToWebProcess::CreateRenderingBackend was getting sent asynchronously and processed by the GPUProcess on the main thread. This would
        cause the creation of the RemoteRenderingBackend object on the GPUProcess side, which would then register itself as a WorkQueueMessageReceiver.
        The issue is that the WebProcess was sending the RemoteRenderingBackend IPC so quickly after the CreateRenderingBackend IPC that when the IPC is
        received (on the IPC thread), the RemoteRenderingBackend has not had a change to register itself as a WorkQueueMessageReceiver yet. As a result,
        some of the early IPC was getting dispatched to the main thread and later IPC would get sent to the RemoteRenderingBackend WorkQueue. This was
        causing RemoteRenderingBackend to get processed out of order.

        To address the synchronization issue for now, I made the GPUConnectionToWebProcess::CreateRenderingBackend synchronous. This may not be the
        best design long term but it is an easy and safe way to resolve this for now. It makes sure the WebProcess cannot send RemoteRenderingBackend
        IPC until after the GPUProcess has created the RemoteRenderingBackend and the RemoteRenderingBackend object has registered itself as a
        WorkQueueMessageReceiver. We probably want to follow-up when we come up with a better design. For now though, I have verified locally that this
        fixes the out of order IPC messaging AND the flaky crashes on these canvas tests.

        No new tests, unskipped existing tests that are no longer flaky.

        RemoteMediaPlayerMIMETypeCache will receive requests to verify whether it can handle a MIME/codec combination,
        as well as whether this indicates a MediaStream, MSE source, or neither. If a cache for the MSE back-end receives
        a query for a MIME type, but the query parameters indicate this is not a MSE source, it will say no and cache the
        response. However the cache is keyed solely on the MIME/codec, so when a subsequent call to create a SourceBuffer
        hits the cache entry, it thinks it will be unable to handle the MIME and rejects.

        Make the mime-type cache triple keyed: use both the raw ContentType (MIME & codecs) as well as the flags stating
        whether the source is a MediaStream, MSE, or neither.

        The crash would occur when the WebPage constructor would end up calling WebProcess::ensureGPUProcessConnection().
        Since we're in the middle of constructing the page, the pageID has been added to m_pageMap but not the page yet.

        [macOS] Refactor logic for presenting the shared QLPreviewPanel when revealing an image
        https://bugs.webkit.org/show_bug.cgi?id=224445
        <rdar://problem/76552762>

        Reviewed by Andy Estes and Devin Rousso.

        `QLPreviewPanel.h` states that `QLPreviewPanel`'s state should never be modified by something that is not
        currently controlling it (where "control" is determined through the `QLPreviewPanelController` category
        methods declared in the same header file). Currently, WebKit code for revealing an image using the shared
        QuickLook panel does not respect this requirement, and instead attempts to set the `dataSource` and `delegate`
        properties of `QLPreviewPanel` out of band.

        While this is not an issue if nothing in the responder chain accepts preview panel control (i.e. implements the
        method `-acceptsPreviewPanelControl:` and returns `YES`), it leads to compatibility issues in apps like Mail
        that override these methods and replace the `dataSource` and `delegate` properties on `QLPreviewPanel`. The end
        result is that `WebPageProxy` ends up in an unexpected state where `WKImageExtractionPreviewController` has been
        created, but will never be destroyed (until the web view itself is destroyed) because we're no longer the
        delegate for the shared `QLPreviewPanel`, and therefore won't receive the teardown message when the preview
        window is dismissed.

        To address this, we refactor this logic so that `WKWebView` (or `WKView`, if applicable) is capable of accepting
        preview panel control. See below for more details.

          and send them to the GPUProcess.
        - Call ensureRemoteRenderingBackendProxy() only if we already have a GPUProcessConnection, to
          avoid eagerly launching the GPUProcess. If no GPUProcessConnection exists,
          WebProcess::ensureGPUProcessConnection() will take care of calling ensureRemoteRenderingBackendProxy()

        This logic used to happen in WebPage::updatePreferences(). However, I had to make it conditional on

        logic when we initiate the GPUProcessConnection to call ensureRemoteRenderingBackendProxy() on the
        WebPages. Note that this is a temporary workaround until we enable DOM Rendering in the GPUProcess.

        (WebKit::WebProcess::setUseGPUProcessForMedia):
        setUseGPUProcessForMedia() gets called when constructing a WebPage, at which point a GPUProcess is
        not useful yet. As a result, we should make sure setUseGPUProcessForMedia() does not call
        ensureGPUProcessConnection() to avoid eagerly launching the GPUProcess and potentially wasting memory.
        To fix this, I moved some of the logic to the GPUProcessConnection constructor so that we do the
        media-related GPUProcess initialization ONLY once we actually have a GPUProcess.

        Reviewed by Eric Carlson.

        When a page calls `navigator.requestMediaKeySystemAccess()` in a background tab, the request
        will be added to a pending request hash map. However, the current implementation of
        `MediaKeySystemPermissionRequestManager` does not send the request when the tab switches
        to foreground. This patch fixes this issue by adding the `MediaKeySystemPermissionRequestManager`

        [GStreamer] CaptureDevice monitor used from UIProcess
        https://bugs.webkit.org/show_bug.cgi?id=222888

        Reviewed by Youenn Fablet.

        GStreamer ports aim to reduce usage of the GStreamer library in the UIProcess and thus
        should not relay capture devicechange monitoring to the UIProcess. For the long term we plan
        to migrate media processing to the GPUProcess but for now we have to maintain the media
        pipelines in the WebProcess. Initializing GStreamer in multiple processes (including the
        UIProcess) has a significant performance impact on embedded platforms, that's why we try to
        avoid it as much as possible.

        The device monitoring code from the UserMediaProcessManager was partly moved to the
        RealtimeMediaSourceCenter so that it can be easily reused by GStreamer ports from the
        UserMediaPermissionRequestManager.

        rdar://71962196

        Reviewed by Alex Christensen.

        Currently each WebIDBServer has a separate thread, so we don't want to create or keep WebIDBServer if it's not 
        in use. There are two cases where network process needs a WebIDBServer:
        1. handle requests from UI process to collect or remove data
        2. handle requests from Web process to perform IDB operations 

        Previously, we created a WebIDBServer when network process connects to a web process, but that does not mean web
        process will perform IDB operations and we may create a thread that's not used. To avoid this, add a new message
        AddIDBConnection for web process to ensure network process has WebIDBServer when it's about to perform operation.

        Also, previously network process removes a WebIDBServer when session is removed and WebIDBServer is not binded 
        with any web process connection. Now we remove WebIDBServer when it's done handling requests, that is count of
        pending requests from UI process is 0 and WebIDBServer is not binded with web process connection. We also remove
        WebIDBServer at when network process is about to be destroyed (NetworkProcess::didClose) so we can break the 
        reference cycle of NetworkProcess-WebIDBServer-IDBServer, and make sure thread exits.

        - Add XRDeviceProxy which implements PlatformXR::Device.
        - Implement WebChromeClient::enumerateImmersiveXRDevices(), which calls PlatformXRSystemProxy

        - XRDeviceProxy goes through PlatformXRSystemProxy to handle its operations.
        PlatformXRSystemProxy sends messages over IPC to PlatformXRSystem on the UI process side,
        which handles XR device discovery and manages sessions via the PlatformXRCoordinator interface.
        PlatformXRSystem::xrCoordinator() returns null for now and will be handled in a later patch.

        Crash under WebProcessProxy::shouldSendPendingMessage()
        https://bugs.webkit.org/show_bug.cgi?id=224377
        <rdar://75329251>

        Reviewed by David Kilzer.

        We are crashing with a null-dereference of pendingMessage.encoder inside WebProcessProxy::shouldSendPendingMessage().
        However, pendingMessage.encoder is a UniqueRef<> and thus cannot be null. Also, we know that the WebProcessProxy
        is alive because WebProcessProxy::didFinishLaunching() has a protector.

        One thing that I believe could theoretically happen and would not be safe though is AuxiliaryProcessProxy::sendMessage()
        being called on a non-main thread. Sending IPC off the main thread is safe in general and something we commonly do with
        an IPC::Connection. To make this safe, IPC::Connection uses a Lock to protect its vector of messages. However, sending
        IPC via an AuxiliaryProcessProxy is currently not thread safe as it relies on the process state (which gets updated on
        the main thread) and access to the m_pendingMessages is not synchronized.
        
        As a speculative fix, I have added logic in AuxiliaryProcessProxy::sendMessage() to dispatch to the main thread if
        we're not already on it. I have also used WTF::DestructionThread::MainRunLoop to make sure all AuxiliaryProcessProxy
        objects get destroyed on the main thread.

        In a follow-up, I am planning to add a release assertion in AuxiliaryProcessProxy::sendMessage() to make sure we're
        on a main thread. We'll then be able to drop the "dispatching the main thread" logic. For now though, I think we
        should start with the "dispatch to main thread" logic, so that we have a patch that we can cherry-pick to a branch.

        Fix by sending windowScreenDidChange() from the UI process, with the synthetic

        REGRESSION (r271660): Tap highlight no longer shows when tapping clickable elements without touch event listeners
        https://bugs.webkit.org/show_bug.cgi?id=224385
        <rdar://problem/76462370>

        Reviewed by Tim Horton.

        In r271660, I added a call to `-finishInteraction` when resetting the synthetic tap gesture to fix a bug where
        it was possible for the tap highlight to remain indefinitely when tapping on a clickable element with a touchend
        event listener. This was because the touch end deferring gesture defers `-_singleTapDidReset:` until after
        `-_didGetTapHighlightForRequest:…nodeHasBuiltInClickHandling:`, where we receive the tap highlight information.

        ```
        2021-04-09 13:05:27.141097-0700 -[WKContentView(WKInteraction) _singleTapIdentified:]

        ```

        However, in the case where there is no touchend event listener and when fast-click is active, we reset the tap
        gesture before receiving the tap highlight information:

        ```
        2021-04-09 13:05:51.836638-0700 -[WKContentView(WKInteraction) _singleTapIdentified:]

        2021-04-09 13:05:51.847196-0700 -[WKContentView(WKInteraction) _singleTapDidReset:]

        2021-04-09 13:05:51.849481-0700   ↳ -[WKContentView(WKInteraction) _finishInteraction]

        ```

        Critically, this means that calling `-_finishInteraction` in `-_singleTapDidReset:` prematurely flagged the
        tap highlight request as complete (by setting `_isTapHighlightIDValid` to `NO`) in the case where we aren't
        deferring gestures, which caused us to avoid showing the tap highlight at all when we eventually receive the tap
        highlight information.

        To fix this, only fade out the tap highlight view in `-_singleTapDidReset:` if the tap highlight request has
        already finished (i.e. `_isTapHighlightIDValid` has been set to `NO`). Additionally, split logic for fading out
        the highlight view into a separate method, and add a `BOOL` flag to make the fading idempotent.

        Also add a testing-only method to report the frame of the tap highlight view. Note that this only attempts to
        return the current `frame` of the tap highlight view instead of converting the frame to the coordinate system of
        the content view (as other similar testing hooks do), since the tap highlight view only exists in the view
        hierarchy for a brief duration.

        Need to propagate and use 'canShowWhileLocked' in the GPU Process
        https://bugs.webkit.org/show_bug.cgi?id=224345
        <rdar://76011262>

        Reviewed by Tim Horton.

        The GPUProcess was previously creating a single visibility propagation view even though
        it was potentially serving several web views. Also, it would also pass
        `canShowWhileLocked=false` when constructing the visibility propagation view, ignoring
        the value of WKWebViewConfiguration._canShowWhileLocked. This would lead to issues for
        apps relying on WKWebView to show content on the lock screen.

        To address the issue, we now have the RemoteRenderingBackend construct its own
        visibility propagation view in the GPUProcess. The GPUProcess constructs a
        RemoteRenderingBackend per WebPage being served so this is convenient. When sending the
        IPC to the GPUProcess to construct the RemoteRenderingBackend, the WebProcess now sends
        the page identifier as well as the value of the canShowWhileLocked flag so that we
        can use the correct canShowWhileLocked flag when constructing the visibility propagation
        view.

        The logic in the UIProcess for dealing with GPUProcess visibility propagation views
        is now almost identical to WebProcess visibility propagation views. They are stored on
        the WebPageProxy and get swapped on process-swap (since a new WebPage gets created).

        Reviewed by Tim Horton.

        Add an optional completion handler argument to `ChromeClient::requestImageExtraction`. If specified, this
        completion handler will be invoked with the image overlay host element (if present), once image extraction
        finishes, or if the element is not suitable for image extraction.

        (WebKit::WebPage::requestImageExtraction):

        Refactor this code, such that the data structure that (weakly) holds elements pending image extraction is
        distinct from the set of elements that have completed image extraction. This allows us to queue completion
        handlers to each element with a pending image extraction request, and invoke them once image extraction is
        finished.

        The existing weak set, `m_elementsWithExtractedImages`, is now repurposed to keep track of only elements that
        have finished image extraction (and may or may not contain an image overlay). The new member variable,
        `m_elementsPendingImageExtraction`, maintains pairs of weak elements and completion handlers; upon finishing
        image extraction, each completion handler corresponding to the element (if it still exists) will be invoked.
        Since the element is weakly held, in the case where the element is destroyed before image extraction finishes,
        we will clean up the (now-null) entries in `m_elementsPendingImageExtraction` when the image extraction request
        is finished.

        [WPE][GTK] Null pointer dereference when child process exits immediately
        https://bugs.webkit.org/show_bug.cgi?id=224209

        Reviewed by Carlos Garcia Campos.

        We discovered that when the child process exits immediately after it is spawned,
        g_subprocess_get_identifier() will return nullptr. In this case, we should crash cleanly
        with SIGABRT via g_error(), rather than crashing with a null pointer dereference inside
        g_ascii_strtoll(). SIGABRT is much nicer than SIGSEGV and indicates that we really do want
        to crash here, whereas SIGSEGV is just a bug.

        Also, let's be careful with our terminology in the existing error message here. Although
        GSubprocess currently always forks, I'm working to make it use posix_spawn() instead, so
        let's not claim that fork() has failed when it soon might not be used at all.

        r274610 introduced a new deferring gesture recognizer intended to prevent several text interaction gestures from
        recognizing during pending image extraction. However, this also causes dragging on iOS to fail, since the
        gesture used to initiate dragging is excluded by the new deferring gesture recognizer. To fix this, allow the
        new deferring gesture to recognize simultaneously alongside all gestures with the exception of only the gestures
        it is intended to defer (i.e. text interaction gestures).

        There is a reasonable chance that by the time we get to the block of xpc_connection_set_event_handler

        Also, the adoption in each entry points was incorrect, causing a late overrelease when tearing down the process.
        It was incorrect because we did not just create the connection or get it from any NS_RETURNS_RETAINED-like function.
        It was causing rare crashes once everything else had released their hold on the connection.

        Make sure we 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 is the set the opacity of our
        root layer to 0 when the JS prompt is requested (before the first paint) and
        set the opacity back to 1 after the first paint.

        To minimize the risks of breakage, the behavior change is behind a
        linked-on-after check. Also, we only trigger this behavior if the WKWebView
        client actually implements the corresponding JS prompt delegate.

        Between the time we were getting the raw pointer to the frame, and the time were were passing it to
        WebPage::runJavaScript(), we were potentially calling WebFrameLoaderClient::dispatchGlobalObjectAvailable().
        It is possible in theory for those synchronous injected bundle calls to mess with the frame tree and cause
        our frame to go bad. As a result, it is best to protect the frame as soon as we get it.

        Add a check to ensure that we don't end up with out-of-bounds memory access when attempting to map an `offset`
        and `capacity` in shared display list data into a `WebCore::DisplayList`. It's possible for this to happen if
        either the sum of `offset` and `capacity` (i.e. the extent of the mapped segment) overflows `size_t`, or the
        extent exceeds the total length of the buffer in shared memory.

        Introduce ScriptBuffer class to wrap SharedBuffer containing a script

        Reviewed by Yusuke Suzuki and Geoff Garen.

        Introduce ScriptBuffer class to wrap SharedBuffer containing a script. We started using SharedBuffer to represent
        worker scripts instead of String, so that they can hold file mapped data and be shared across processes.
        This patch introduces a new ScriptBuffer to wrap those SharedBuffers. The type makes it clearer what type of
        data we're dealing with. The helper functions used to convert between String and SharedBuffer can now simply
        be member functions on ScriptBuffer. This also simplifies IPC code.

          becomes much simpler.

        Allow wheel events to trigger high frequency DisplayLinks
        https://bugs.webkit.org/show_bug.cgi?id=224095

        Reviewed by Sam Weinig.

        When scrolling via wheel events, we may want to drive scrolling tree updates
        (which are driven by EventDispatcher::displayWasRefreshed()) at a higher rate
        than the main thread does rendering updates.

        To support this, give DisplayLink a count of "full speed" clients, and when this count is
        greater than zero, have DisplayLink::notifyObserversDisplayWasRefreshed() send
        EventDispatcher IPC at full framerate, while passing a flag based on the usual
        relevantForUpdateFrequency() about whether to update the main thread for a given update.

        Allow DisplayLink connection info objects with non-zero fullSpeedUpdatesClientCount
        to stick around, because that fullSpeedUpdatesClientCount needs to be stored for
        connections that may not yet have observers.

        Since DisplayLink might have info for connections with no observers, adjust the logic in
        DisplayLink::notifyObserversDisplayWasRefreshed() to do the CVDisplayLinkStop
        after traversing the observers.

        The "full speed" client count is maintained by a HysteresisActivity on WebPageProxy,
        whose impulse is wheel events. This replaces a singleton HysteresisActivity which
        was used to determine whether IPC goes to EventDispatcher or the main thread of
        the web process.

        WebPageProxy needs to track the PlatformDisplayID for the screen that its view is on,
        so it knows which DisplayLink to message.

        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.

        Release CoreGraphics resources (Metal device command buffers,
        and other per-device resources) 1s after last
         - RemoteRenderingBackend drawable resource
         - RemoteGraphicsContextGL instance
         - RemoteMediaPlayerProxy instance
        has been destroyed.

        Adds ScopedRenderingResourcesRequest and
        ScopedWebGLRenderingResourcesRequest to hold the intent to
        use the global rendering resources. The names are called 'Request'
        because the implementation is not guaranteed to do anything specific.
        E.g. ResourcesRequest == "I'd like the resources to be available"
             ResourcesLock, ResourcesHolder, ...  = "The resources are guaranteed
             to be held."
        The naming tries to be consistent with the similar class
        ScopedHighPerformanceGPURequest.

        For sequence like:
        1) Visit a page with simple Context2D usage
        2) Close the page (but leave the browser running)
        This saves 2mb of IOAccelMemory at step 2 on a tested device.

        (WebKit::GPUConnectionToWebProcess::didClose):
        Clear the map containing RemoteGraphicsContextGL objects
        when connection to WebContent process is closed.
        This stops the RemoteGraphicsContextGL listening for IPC
        and destroys them in scenarios where the connection is
        closed but the GPUConnectionToWebProcess is staying alive
        for some reason. In this patch, this would happen for example
        during reload of the page.

        A RemoteRenderingBackend might exist without any drawable due to
        a) Context2D being created and then destroyed
        b) WebGL taking a reference to the RemoteRenderingBackend in order
        to submit work in case the caller would request Image -> texture
        upload.

        In case of WebGL context being created and then destroyed, there is
        a RRB instance alive but not doing any rendering. In these cases,
        we want the rendering resources to be released and not held by
        the empty RRB.

        WebKit::ShareableHandle whenever possible. This way, when the NetworkProcess sends a
        ServiceWorkerContextData to the ServiceWorker process to launch a service worker, both the
        ServiceWorker process and the Network process share the same mmap'd versions of the scripts and we
        save on dirty memory use. This helps reduce dirty memory use in the ServiceWorker process in the
        warm case, where the scripts are loaded straight from the disk (via SWScriptStorage).

        Web Inspector: [Cocoa] WKInspectorResourceURLSchemeHandler can exceed the soft thread limit when opening multiple inspectors simultaneously.
        https://bugs.webkit.org/show_bug.cgi?id=223958

        Reviewed by BJ Burg.

        In engineering builds, the Web Inspector is loaded as hundreds of separate resources instead of the handful of
        minified sources used for released builds. When two Web Inspector windows are opened their loads can overlap
        and it is possible for the sum total of file load operations to exceed the dispatch soft thread limit. To
        resolve this, we set a sensible limit to the number of simultaneous inspector loading operations. A higher
        number of allowed concurrent operations yielded no noticeable increase in load speeds.

        If the UIProcess exits or severs it connection to the WebProcess while the WebProcess is
        launching, the WebProcess ends up getting an invalid mach port upon initialization. This
        is expected and XPCServiceInitializerDelegate::getConnectionIdentifier() was dealing with
        this. getConnectionIdentifier() was checking if the port was invalid by checking if it was
        MACH_PORT_NULL and calling exit() in such case. However, something has changed (likely
        at OS level) and we are now sometimes getting MACH_PORT_DEAD instead of MACH_PORT_NULL.
        The proper way to check if a mach port is valid is to call MACH_PORT_VALID(), which checks
        for both MACH_PORT_NULL and MACH_PORT_DEAD. I therefore updated getConnectionIdentifier()
        to use MACH_PORT_VALID() instead of an explicit check for MACH_PORT_NULL. This gets rid
        of debug assertions we were seeing in the output of some iOS unit tests.

        PCM: Introduce PrivateClickMeasurementNetworkLoader
        https://bugs.webkit.org/show_bug.cgi?id=222217
        <rdar://74817863>

        Reviewed by Youenn Fablet.

        This patch refactors PrivateClickMeasurementManager to use a newly introduced PrivateClickMeasurementNetworkLoader
        instead of the PingLoad to handle network traffics such that PCMM can receive and process response bodies.

        PrivateClickMeasurementNetworkLoader is a stripped down version of the ServiceWorkerSoftUpdateLoader, which is also
        a derived class of NetworkLoadClient.

        Covered by new test contents within existing test files.

        [GPU Process]: Improve getImageData() perf part 2: Use shared memory and a semaphore
        https://bugs.webkit.org/show_bug.cgi?id=223732

        Reviewed by Ryosuke Niwa.

        This patch implements a design for getImageData() where the web process and the GPU process
        set up a shmem + semaphore ahead-of-time, so that when we encounter a call to getImageData(),
        the GPU process can just write into the shmem and signal the semaphore. The web process just
        encodes the getImageData() call into the regular display list, flushAsync()s to kick the GPU
        process, then just waits on the semaphore. Initial performance testing shows that this is
        way, way faster than sending messages containing pixel color data payloads.

        This patch causes a ~40% progression on the Images test in MotionMark on my Mac with the GPU
        process enabled. When compared to the GPU process disabled, the results after just running
        just a few times seem to be pretty close (within the noise).

        If we need more performance, the next step is to try to reduce the memcpy()s.

        No new tests because there is no behavior change.

        Migrate _WKUserContentExtension and older versions of WKContentRuleList to WKContentRuleList during lookup
        https://bugs.webkit.org/show_bug.cgi?id=223831

        Reviewed by Brady Eidson.

        r275078 incremented CurrentContentRuleListFileVersion for the first time in a few years.
        As a result, we will get a WKErrorContentRuleListStoreVersionMismatch during lookup for existing compiled WKContentRuleLists.
        To make this as compatible as possible, if we see such a WKContentRuleList, try extracting its source and recompiling.

        Also, _WKUserContentExtension is used by Safari and being migrated from in rdar://75889414.
        To make this succeed and not leave any files behind, we move legacy files to modern filenames during lookup.
        We also remove them if they're there when removing the WKContentRuleList from the WKContentRuleListStore,
        and we include them in getAvailableContentRuleListIdentifiers.  compileContentRuleList only compiles to the modern locations,
        and invalidateContentRuleListVersion is only used for tests.  All this is done on non-main WorkQueues, so the few additional
        file reads/writes aren't an issue.

        Luckily, _WKUserContentExtensionStore was only used by Safari, and its defaultStore was never used.

        All this is covered by API tests.

        Plumb DisplayUpdate through the display refresh monitors
        https://bugs.webkit.org/show_bug.cgi?id=223847

        Reviewed by Sam Weinig.

        Future work will allow DisplayRefreshMonitorClients to request different frame rates, which
        are whole fractions of the display's nominal refresh rate. These various frame rate requests
        flow up through the DisplayRefreshMonitors, and in WebKit2, up through IPC to the
        per-display DisplayLink which may even service multiple processes.

        For power reasons, we don't want to trigger display refresh notifications down the chain at
        the highest possible frequency; at various stages of propagation the rate might be halved if
        that's necessary for downstream clients.
        
        To make this frequency splitting logic simple, this patch introduces DisplayUpdate, which
        represents an update of the display, and contains data about it in the form of a numerator
        is the frame index, and the denominator is the nominal frame rate. Frame index wraps to zero
        every second.
        
        For example, a 60Hz display will generate display refreshes with DisplayUpdates which
        sequentially will be { 0, 60 }, { 1, 60 }, { 2, 60 } ... { 59, 60 }, { 0, 60 }. The
        zeroth frame is at some arbitrary time and not aligned with wallclock time.
        
        Thus a client with a 30Hz update requirement can simply ignore every odd-numbered frame, and
        a client downstream from it with a 15Hz requirement, which only receives those even-numbered
        frames, still has enough information to compute which frames to ignore.
        
        Classes which are sources of callbacks for DisplayRefreshMonitor need to generate these
        DisplayUpdates; that includes the various platform DisplayRefreshMonitor subclasses in
        WebCore, and those in WebKit that live in the UI process and trigger updates over IPC.

        Reviewed by Chris Dumez.

        The existing behavior for DisplayRefreshMonitors was that they were created and destroyed
        frequently, as their clients are registered and unregistered. In addition, some of
        their subclasses had duplicated logic related to how often they fired without clients
        before they were removed.

        The 1:1 correspondance between DisplayRefreshMonitors and physical displays makes them
        a useful place to store per-display information (like refresh rate), which should
        persist whether or not they have clients, so this change prepares for that.
        
        The main changes in this patch are:
          1. Provide virtual startNotificationMechanism()/stopNotificationMechanism() functions on
             DisplayRefreshMonitor that subclasses can use to start their CVDisplayLink or related
             functionality.

          2. Provide some shared maxUnscheduledFireCount logic that subclasses can tune to
             provide the hysteresis used to control the start/stop of the underlying
             notification mechanism.

         3. Provide a shared dispatchDisplayDidRefresh() function that most implementations
            can use.

        Refactor NetworkSessionCocoa to prepare for per-WebPageProxy sessions
        https://bugs.webkit.org/show_bug.cgi?id=223776

        Reviewed by Alex Christensen.

        No new tests (No behavior change refactor)

        A NetworkSessionCocoa has (n) NSURLSessions associated with it.
        
        When a network load needs to happen - based on the context for that load - the appropriate
        NSURLSession is chosen (or created).
        
        In a future patch, there will be an additional bit of context used for choosing the appropriate
        NSURLSession - The WKWebView the load was triggered from.
        
        This patch takes those (n) NSURLSessions and wraps them in a SessionSet object.
        It also adds the concept of looking up the appropriate SessionSet based on the WebPageProxyIdentifier
        triggering the load.
        
        This patch by itself should not be a behavior change, but allows the followup to be much simpler.

        Implement PCM SQLite changes based on spec review
        https://bugs.webkit.org/show_bug.cgi?id=223726
        <rdar://problem/75818526>

        Reviewed by Brent Fulgham.

        This patch makes 2 significant changes in the SQLite database for
        PCM. First, it renames attributeOnSiteDomainID to destinationSiteDomainID
        based on spec review. Second, it adds support for sending reports to
        both click source and destination sites. This involved adding an
        additional column to the AttributedPrivateClickMeasurement table to
        store the earliest time to send a report to the destination, renaming
        the earliestTimeToSend column to specify source, and removing the NOT NULL
        constraint on earliestTimeToSend in order to mark in the database when
        a report has been send to the source site.

        Since we need to remove a NOT NULL constraint and update foreign keys
        and unique constraints, this requires a full migration of data from
        the PCM tables.

        [iOS] Date picker view jumps to center when switching between MobileSafari and another app
        https://bugs.webkit.org/show_bug.cgi?id=223662
        <rdar://problem/74748727>

        Reviewed by Tim Horton.

        Tapping on a date input presents a UIDatePicker inside of a
        UIContextMenuInteraction. The presentation of context menus is
        dependent on the _positionInformation in WKContentViewInteraction being
        up-to-date.

        To ensure the value is up-to-date, a position information request is
        made prior to presenting the date picker. However, the location used
        for the request is the current FocusedElementInformation's
        lastInteractionLocation. This is fine in most cases, since the date
        picker is usually present immediately after tapping on the date input.
        However, the date picker can be closed and presented again when
        switching between MobileSafari and another app, as the input is focused
        again when MobileSafari is reopened. If the switch is performed using a
        gesture, the last interaction location is modified. Consequently, the
        last interaction location does not always correspond to the position
        of the date input, and the position information request gives us
        incorrect information, leading to incorrect presentation of the picker.

        To fix, add a new way of presenting context menus that is not dependent
        on position information. Instead, form controls can use the information
        they already have in FocusedElementInformation to present their
        peripherals.

        No new tests, since this bug only reproduces when swiping to switch apps.
        Other touches in the web view immediately dismiss the date picker, making
        the bug difficult to reproduce in a test.

        Remove a redundant call to elementDidRefocus following r258333. The
        FocusController already calls elementDidRefocus before this point, when
        the mousepress event is dispatched.

        The redundant call was uncovered when making the context menu
        presentation synchronous, and causes problems with the presentation.
        Specifically, the first call to elementDidRefocus causes the context
        menu to be presented. The second call then results in an attempt
        to scroll the web view, since the context menu can obscure the
        assisted node. The additional scrolling is unwanted behavior, since it
        does not occur when focusing the node for the first time.

        This issue was previously unobserved, since the asynchronous presentation

        This bizarre behavior is triggered by removing the <input type=file> element inside an onclick() handler
        for the input element. This confuses safaridriver, which expects to be able to query the file input's .value
        via JavaScript after setting the files.

        As part of the fix, provide the list of selected filenames in the Automation.fileChooserDismissed event.
        On the safaridriver side, just use the list of filenames provided in this event to avoid an extra JS evaluation
        that may race with page content.

        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.

        All Books quirks are flakily not applied in modern WebKit
        https://bugs.webkit.org/show_bug.cgi?id=157101
        <rdar://problem/25965028>

        Reviewed by Darin Adler.

        In r200121, a quirk was introduced that queried the isIBooks()
        RuntimeApplicationChecks method from inside commonVM().

        RuntimeApplicationChecks bundle checks cache the result of the bundle
        check, and, as such, must not be called until the bundle identifer of
        the UI application is known. In legacy WebKit, this is not a problem,
        because the check is running in the application process; in modern WebKit,
        there is a short window between process launch and the InitializeWebProcess
        message being received where we won't know the bundle identifier, and if
        isIBooks() (or any other bundle check) is called during this time, it will
        cache the wrong result.

        It is possible for commonVM() to be called in this window; one possible path
        to this is by triggering an os_log_fault during this time, which WebKit
        observes (via os_state_add_handler()) in order to dump memory usage
        (which happens to call commonVM() and results in isIBooks getting called
        and caching the wrong value).

        Add an assertion, and move the quirk to live as a setting on the process
        pool configuration, to be set via SPI by Books, instead of as a bundle check.

        Also, ensure that client bundle identifier and SDK version are set in 
        all WebKit subprocesses, so that bundle/SDK checks work everywhere
        (previously, the GPU process was using SDK checks without having pushed
        the values from the UI process, resulting in incorrect results, and
        running afoul of the assertion added above).

        Ignore middle commits during animated resize

        Reviewed by Tim Horton.

        For animated resize, UI process sets layer transform to fit new size until web process picks up size change and 
        paints. It is possible that UI process receives a commit during animated resize and the commit is not for the 
        animated resize (web process commits before animated resize). In this case, our current implementation is: if 
        SPI client species there will be no other update (!_waitingForEndAnimatedResize), we change layer transform to
        reflect change of the middle commit. 

        However, that commit does not mean web process issues new paint, so the adjustment can be wrong. We find the 
        handling of middle commits causes issues in SPI client's use case  (rdar://47623140). Also by manual testing, 
        it's not clear how the code can benefit current SPI clients. It seems to cause the same trouble sometimes. So 
        let's just remove it.

        Fixes this error:

          error: invalid 'static_cast' from type 'uintptr_t' {aka 'unsigned

        ; an invalid 'static_cast' from type error for ARMv7 (rpi3 and mesa driver)
        by using the same solution chosen in
        https://bugs.webkit.org/show_bug.cgi?id=179511:

          EGLNativeWindowType can be aliased to a different type depending (at least) on the EGL
          implementation, its build options, and the libepoxy build options.  Using "static_cast"
          works when it is a numeric value and the width of the value needs to be optionally
          extended to 64 bits (e.g. the EGL type is "int" in a 32-bit CPU) but not for pointers,
          and using "reinterpret_cast" works when the size of a pointer is 64 bits but not in other
          cases. Therefore it seems reasonable to use a plain C cast expression to solve this
          particular situation.

        [iPadOS] Stale checked item when reopening <select>
        https://bugs.webkit.org/show_bug.cgi?id=223592
        <rdar://problem/75629529>

        Reviewed by Wenson Hsieh.

        Reopening a select element after changing its value displays the
        original value as checked, rather than the current value on iPadOS. This
        is incorrect, since the checked value in the context menu should match
        the selected value in-page.

        The behavior is incorrect on iPadOS, but works correctly on iPhone, since
        dismissing input peripherals on iPhone blurs the focused element,
        resulting in a new peripheral being created each time. However, on iPad
        the same peripheral is reused when interacting with the same element.
        Since the presented UIMenu is only created once during the initialization
        of the peripheral, the checked item can be stale on iPads. To fix, update
        the menu each time the peripheral is presented, rather than each time it
        is created.

        Web Inspector: rename WebInspectorProxy to WebInspectorUIProxy

        Reviewed by Devin Rousso.

        To improve clarity in the codebase, I'm renaming this to be consistent
        with it's WebProcess-side counterpart, WebInspectorUI. There are many
        different classes with the 'WebInspector' prefix, so it can be difficult
        to understand whether a class is associated with the WebInspectorUI
        frontend or the InspectorController backend. This fixes one of the biggest
        offenders.

        For brevity, I have elided function-level changelog entries from files
        that have been renamed. This is a mechanical refactoring.

        Remove unused JS and CSS files of media controls
        https://bugs.webkit.org/show_bug.cgi?id=214955
        <rdar://problem/66604040>

        Reviewed by Eric Carlson.

        Cocoa platforms are already using modern media controls so there's no reason to keep the old
        media controls resources/logic around any longer. It just wastes space.

        The non-iOS Apple controls must be kept though as they are still used on Windows.

        (WKPreferencesSetModernMediaControlsEnabled): Deleted.
        (WKPreferencesGetModernMediaControlsEnabled): Deleted.
        Replace `ModernMediaControlsEnabled` setting with `ENABLE_MODERN_MEDIA_CONTROLS` build flag.

        * UIProcess/mac/WKFullScreenWindowController.mm:
        Update the static `minVideoWidth` value for modern media controls.

        [WinCairo] ASSERTION FAILED: isMainThread() in GPU process for some canvas/philip/tests tests
        https://bugs.webkit.org/show_bug.cgi?id=223500

        Reviewed by Alex Christensen.

        In WinCairo GPU process mode, WebCore::Font IPC decoder was using
        FontCache::fontForFamily that should be called only in the main
        thread. However, It is was called in IPC thread. Reimplemented the
        decoder without using FontCache::fontForFamily.

        Encode LOGFONT for WebCore::Font, and decode it and create a font
        directly from it.

        This change also encodes and decodes the
        FontPlatformData::CreationData of custom fonts. However, custom
        fonts still don't work in GPU process mode because
        FontCustomPlatformData is destructed soon. In non-GPU process

        The code was implicitly casting an uint64_t identifier into a BOOL variable. The intention was
        to check whether the identifier is 0 or not. To silence the UBSAN error, we now use the bool
        type instead of BOOL (since BOOL is defined as a signed char on some platforms).

        The `didLoadingProgress()` function of `MediaPlayerPrivateAVFoundation`
        and `MediaPlayerPrivateMediaSourceAVFObjC` changes their mutable member
        variables, so a caller (e.g., RemoteMediaPlayerProxy::didLoadingProgress())
        will get false eventually if it calls the function repeatedly. As a result,
        `MediaPlayerPrivateRemote::didLoadingProgress()` will always return false.
        This patch fixes this issue with a new synchronous message in `RemoteMediaPlayerProxy`.

        No new tests. Fix a test failure.
