        WebBackForwardListItem::setPageState should receive pageState by rvalue reference
        https://bugs.webkit.org/show_bug.cgi?id=199535

        Reviewed by Alex Christensen

        Coverity is complaining here about copying PageState by value in the parameter list. It's
        sort of a false positive, in that the PageState really does need to be copied here, so this
        is the best we can do. But pass by value and then WTFMove() is a pretty strange way to write
        it. Passing by rvalue reference would be better. This makes the copy more clear.

        Mitigates a crash wherein we end up calling the completion handler of
        -requestAutocorrectionContextWithCompletionHandler: within a nested call
        to -requestAutocorrectionContextWithCompletionHandler:. In this particular
        case, a sync `window.open` from the web process to the UI process happens
        while the UI process is already handling a sync autocorrection context
        request. This causes the UI process to try and immediately dispatch the
        incoming sync message to avoid deadlock. However, Safari's logic to create
        and set up a new web view when opening a new window makes the new view the
        first responder, which then prompts UIKit logic to request an autocorrection
        context for the new web view.

        To avoid the issue for now, simply use -resignFirstResponder as a cue to invoke
        pending autocorrection context handlers in the original web view before UIKit
        tries to request autocorrection context in the newly created view.

        I attempted to write a test for this, but realized that we only end up hitting
        the debug assertion pointed out in <https://webkit.org/b/199680>; we should be
        able to write a test for this in the future, if we teach Connection to handle
        multiple outgoing sync messages.

        The UIContextMenuInteraction calls didEndInteraction before executing the

        IPC::Connection::waitForMessage() is crashing due to a null defererence of
        m_waitingForMessage. Since m_waitingForMessage is only ever set to null in
        waitForMessage(), this seems to imply we've re-entered waitForMessage().
        This is in theory possible since the loop inside waitForMessage() calls
        SyncMessageState::singleton().dispatchMessages() on every iteration to
        process incoming synchronous IPC messages. In theory, one of these sync
        IPC messages could run code which ends up calling waitForAndDispatchImmediately()
        (and thus waitForMessage()).

        We had a debug assertion to try and catch re-entrancy with a comment stating
        "We don't support having multiple clients waiting for messages." but we
        would not see those in release and we would crash with a null dereference
        instead.

        To address the crashes in release, return early in case of re-entrancy
        (we would still hit an assertion in debug).

        [Pointer Events] Scroll indicators should not show for scrollable content with touch-action: none
        https://bugs.webkit.org/show_bug.cgi?id=199618

        Reviewed by Simon Fraser.

        Even though we correctly didn't scroll when "touch-action: none" was specified on an element, we would only apply
        scrolling constraints after the panning gesture was recognized and the backing UIScrollView would show its scroll
        indicators. While this is correct when only "pan-x" or "pan-y" is specified, we should not show the scroll indicators
        at all for "touch-action: none" since no scrolling should happen.

        To do this, we add a new method to the WKTouchActionGestureRecognizerDelegate protocol to indicate whether a given
        gesture recognizer may pan content in the WKWebView. If the gesture recognizer is the top-level scroll view or one
        created within the page to back "overflow: scroll" content or an iframe, we correctly make that gesture recognizer
        fail to recognize if neither "pan-x" nor "pan-y" is specified for this touch identifier.

        out to show open tabs in Safari on iOS. We add a new WKUIDelegatePrivate method that will allow Safari to indicate
        that a UIPinchGestureRecognizer considered for prevention would lead to pinch-to-zoom behavior.

        [Pointer Events] Use a gesture recognizer to prevent pinch-to-zoom behavior
        https://bugs.webkit.org/show_bug.cgi?id=199543

        Reviewed by Dean Jackson.

        We used to set the "enabled" property on the main UIScrollView's UIPinchGestureRecognizer to disable pinch-to-zoom
        behavior based on the "touch-action" CSS property. This was sub-optimal since this gesture recognizer can be publicly
        accessible by third-party developers, but also because it set state instead of a run-time solution.

        We now introduce a new WKTouchActionGestureRecognizer dedicated to preventing clearly identified gesture recognizers
        from being recognized to disable some built-in behavior. As a new touch starts, we record the computed touch-action
        property for the given touch identifier on the WKTouchActionGestureRecognizer, then WKTouchActionGestureRecognizer
        determines, by implementing -[canPreventGestureRecognizer:], whether the possibly-prevented gesture recognizer
        is known to lead to a pinch-to-zoom behavior and whether it contains a touch that should prevent it.

        To support the WKTouchActionGestureRecognizer, WKContentViewInteraction implements the new WKTouchActionGestureRecognizerDelegate
        protocol to indicate whether the possibly-prevented gesture recognizer is the main UIScrollView's UIPinchGestureRecognizer.

        No new test since this changes the implementation of existing behavior.

        <rdar://problem/40569615>

        Reviewed by Simon Fraser.

        Mitigations introduced in r227759 prevent a touch inside a document of origin A to result in a click event being
        dispatched on an element inside a document of origin B. It accomplishes this by keeping track of the security
        origin of the last touch via m_potentialTapSecurityOrigin on WebPage. However, there exists a corner case in
        which m_potentialTapSecurityOrigin, set after touching a document in a subframe, may persist even after the user
        has finished interacting, causing taps in subsequent documents to not result in synthetic click events due to
        mismatched potential tap origins.

        This may happen if the first user gesture happens inside an element in a subframe with touch event handlers, but
        no click event handler (and the touch is additionally not over some clickable element). In this case,
        m_potentialTapNode is set to null in WebPage::potentialTapAtPosition, and when we consult it in
        WebPage::commitPotentialTap, we just end up calling commitPotentialTapFailed(); and return early. This means
        that m_potentialTapNode, m_potentialTapLocation, and (importantly) m_potentialTapSecurityOrigin are not reset.
        This causes subsequent taps in the top-level document to never dispatch click events, if the security origin
        does not match with that of the subframe.

        To fix this, we add a new async IPC message from the UI process to the web process to ensure that our current
        security origin is reset before attempting to handle a tap.

        Touching media controls sometimes shows software keyboard

        <rdar://problem/52076270>

        Reviewed by Eric Carlson.

        In r243044, we added a compatibility hack for Google Slides (and other G-suite properties) to allow the on-
        screen keyboard to show up after a prevented touch event in the case where an element was already focused, even
        if the touch event handler doesn't explicitly refocus the element. However, this means that if a regular text
        field (or other form control) has been programmatically focused, then interacting with any other element that
        prevents default on touchstart will cause us to show the keyboard for that focused element.

        To mitigate this, only fall down this refocusing codepath in the case where the focused element is a hidden
        editable element (in the style of many Google productivity web apps). For non-hidden editable elements that are
        already focused, this refocusing logic is not necessary, since the user should be able to interact with the
        control to show the keyboard anyways; for hidden editable areas, this compatibility hack is actually needed,
        since there is typically no other way for a user to focus these elements and show an on-screen keyboard.

        Simplify logic that handles registering WebProcessProxy objects with their WebsiteDataStore to make

        The following changes were made:
        1. The WebProcess now registers / unregisters itself directly with its WebsiteDataStore when needed,
           instead of having the WebPageProxy/ProvisionalPageProxy be in charge of calling the right
           WebProcessLifetimeTracker / WebProcessLifetimeObserver abstractions.
        2. The WebProcessLifetimeTracker / WebProcessLifetimeObserver abstractions were dropped. The
           WebsiteDataStore was the only observer.
        3. The WebProcessProxy is now registered with its WebsiteDataStore as soon as it has a page (provisional
           or not) instead of waiting until the process has finished launching. This simplifies the logic a
           lot and waiting until the process has launched is not needed by the WebsiteDataStore.

        The ResourceLoadStatisticsStore object is constructed / used / destroyed on a background queue.
        It is therefore not safe to use a WeakPtr to the ResourceLoadStatisticsStore on the main thread.

        dispatching to the main thread and use this store on the main thread instead of weakThis->m_store.

        To harden our code, I added debug assertions to make sure that this HashMap is only used on the main thread and
        to make sure that the sessionID used as key is always valid. I have also added if checks to avoid crashing in
        release whenever possible.

        Note that we came to a similar conclusion for NetworkProcess::m_swServers when investigating rdar://problem/51859081,
        so the two radars are potentially related. Both HashMaps are owned by the NetworkProcess and use a SessionID

        [iOS] REGRESSION (r246757): Unable to select non-editable text in subframes
        https://bugs.webkit.org/show_bug.cgi?id=199366
        <rdar://problem/52460509>

        Reviewed by Tim Horton.

        r246757 removed logic in selectionPositionInformation responsible for setting the focused frame when handling a
        position information request. As the FIXME formerly in InteractionInformationRequest.h alluded to, text
        selection gestures on iOS were dependent on this behavior when selecting text in subframes, since text selection
        helpers in WebPageIOS.mm assume that the focused frame already contains the selection being set.

        Rather than calling setFocusedFrame when requesting position information, we can fix this by making
        WebPage::selectWithGesture and WebPage::selectTextWithGranularityAtPoint both set the focused frame if needed
        before extending or moving text selections.

        Covered by layout tests that began to fail after r246757:

        In iOS 12, when scrolling a text selection in an fast-scrolling container, editor state updates are scheduled
        under AsyncScrollingCoordinator::updateScrollPositionAfterAsyncScroll after the end of the scrolling gesture,
        when the scrolling layer action is ScrollingLayerPositionAction::Set. This is no longer the case in iOS 13,
        because we now bail in ScrollingTreeScrollingNode::wasScrolledByDelegatedScrolling after scroll deceleration
        finishes since the scroll position didn't end up changing. Additionally, we no longer use
        ScrollingLayerPositionAction::Set in the case where scrolling finished decelerating, since
        ScrollingTreeScrollingNodeDelegateIOS::scrollViewDidScroll no longer uses to value of inUserInteraction to
        determine whether to Set or Sync scrolling layer positions.

        To restore iOS 12 behavior, ensure that we send a scrolling tree update using ScrollingLayerPositionAction::Set
        after scrolling ends.

        [iOS Scrolling] Propagate scrolls to non-nested UIScrollViews
        https://bugs.webkit.org/show_bug.cgi?id=199222

        Reviewed by Simon Fraser.

        We may generate scrolling hierarchies where the scrolling ancestor of a layer is not
        an ancestor in the layer tree. We  handle this in most situations but there is still
        a problem where a scroller fails to propage scroll to the ancestor when it reaches
        the edge.

        This patch hooks up a new SPI that allows us to tell UIKit about non-ancestor scrolling
        relations and solve this problem.

        -[WKContentView _selectionClipRects] returns a bogus value in -reloadInputViews when focusing an element
        https://bugs.webkit.org/show_bug.cgi?id=199310
        <rdar://problem/52292137>

        Reviewed by Megan Gardner.

        When reloading input views under -_elementDidFocus:, -_selectionClipRect returns the value of the previously
        focused element; this is because _selectionClipRect depends on EditorState's post layout data, which is only
        guaranteed to arrive during the next remote layer tree commit after the element is focused.

        However, some clients need to inspect this value under the call to -reloadInputViews when an element is focused;
        to make this work, simply check whether we are currently waiting for post-layout EditorState data to arrive
        following element focus; if so, return the FocusedElementInformation's elementRect, which represents the initial
        state of the focused element. Otherwise, use the EditorState's post layout data, which is guaranteed to be more
        up-to-date than the FocusedElementInformation's element rect.

        Following <rdar://problem/47333786>, UIKit now asks WebKit whether it can handle Command + A as
        "select all" instead of just demanding that we handle it. So, WebKit needs to be able to correctly
        tell UIKit in advance whether it can handle it. Currenlty WebKit tells UIKit it cannot handle a
        "select all" whenever there is an existing range selection. So, UIKit does not tell WebKit to
        perform the "select all". Moreover, since UIKit has no other means to handle this key command
        itself it tells WebKit the key command was not handled. So, WebKit tells the keyboard to insert
        the "a". Instead, WebKit should tell UIKit it can handle a "select all" even when this is an
        existing range selection. However we need to keep the current logic just for when UIKit is
        asking us with respect to populating the callout menu to not regress platform behavior.

        This was wrong, because -contextMenuInteractionDidEnd: can be called before

        Reviewed by Geoffrey Garen.

        r246526 adds a lock m_localStorageNamespacesMutex to protect m_localStorageNamespaces, because 
        m_localStorageNamespaces is destroyed at main thread while accesses to m_localStorageNamespaces happen in the 
        background thread.
        After r246526, getOrCreateLocalStorageNamespace acquires lock m_localStorageNamespacesMutex when 
        m_localStorageNamespacesMutex is already acquired in cloneSessionStorageNamespace, so the StorageManager thread
        hangs.
        To solve this issue, we can remove the lock in getOrCreateLocalStorageNamespace, or we can remove the 
        m_localStorageNamespacesMutex. waitUntilWritesFinished() before ~StorageManager() already guarantees nothing 
        will be running in the background thread, so it is unlikely we the access to m_localStorageNamespaces in the 
        background thread would collide with the destruction of m_localStorageNamespaces. Also, we don't need 
        didDestroyStorageArea as LocalStorageNamespace can hold the last reference of StorageArea after r245881.

        The fall back to web path mechanism in SubFrameSOAuthorizationSession doesn't actually resume
        the previous navigation. Instead it starts a new one. The current implementation doesn't carry
        any information from the previous navigation. It is problematic when it comes to http referrer
        as the server might use that to determine what kind of responses to send back. Therefore, we
        add that information now.

        Currently, the heuristic to determine whether the page should be shrunk to fit the content width after loading
        works by checking whether the page's content is wider than the layout width we've provided for the page.
        However, in the case where an explicit width larger than the true view width is specified by the page's meta
        viewport, we'll end up believing that the page's content is not wider than the layout width, which is dictated
        by the fixed meta viewport width. Instead, we can shrink the page down in this scenario by comparing the content
        width against the scaled size of the view when computing the amount of horizontal overflow.

        m_focusedElement != &element in WebPage::elementDidBlur() sometimes

        This can happen when the focused editable element is inside a nested frame and a person
        taps outside that frame. For reasons that seem lost to time, WebKit2 on iOS would mutate
        the focused frame whenever computing selection positioning information (say, for a tap).
        This "quirk" was added in r163476, but that code has go through multiple iterations and
        is no longer comparable to the current code. Yet, the original mutation of the focused
        frame remained. As a result the UI process and Web process go out of sync with respect
        to what each thinks is the focused element and this visually manifest itself in at least
        two ways:

            1. A non-sensical DOM focus event would be dispatched at the frame tapped, but
            we would keep the focused element focused.

            2. Because we would keep the focused element focused in (1), even though its frame
            is not focused, the keyboard would be active (software keyboard on screen or candidate bar
            on screen if a hardware keyboard is attached), but appear unresponsive: any keys pressed
            would not cause text to be typed into the editable field.

        Because of (1) it was possible for m_focusedElement != &element in WebPage::elementDidBlur().
        When this happens the UI process would never receive an ElementDidBlur message and hence would
        not clear out the focused element state and hide the keyboard.

        We neither do this frame focus mutation in Legacy WebKit on iOS nor Mac. Let's remove this quirk.
        If it turns out that it causes a compatibility issue then we will be in a better position to
        understand its purpose and consider bringing this quirk back, if needed.

        Use theme_base_color instead of white background for swipe gesture fallback if no snapshot is found and
        the page did not specify a color. This allows it to use dark colors for dark themes. If the color was

        Add OverflowScrollProxyNodes to the scrolling tree
        https://bugs.webkit.org/show_bug.cgi?id=199132

        Reviewed by Antti Koivisto.

        Add ScrollingStateOverflowScrollProxyNode and ScrollingTreeOverflowScrollProxyNode. These
        nodes represent clip and scroll position for an overflow:scroll in the containing block chain,
        but not the paint ancestor chain of a layer. They will be used to correctly manipulate clip
        rects for composited layers in non-stacking-context scrollers, and in a future patch will
        replace the functionality of "Moves" positioned nodes.

        An OverflowScrollProxyNode has the ScrollingNodeID of the scrolling node that it relates to,
        and we use the existing "related overflow nodes" to create the back references in the scrolling tree.

        These nodes are not instantiated yet; a future patch will hook them up.

        WKPasswordView.mm is used on iOS-family devices. However, it doesn't
        build on tvOS or watchOS when "treat deprecation warnings as errors"
        is enabled. This build failure is due to a reference to
        UIColor.groupTableViewBackgroundColor in a branch of non-dark-mode
        code. Address this by surrounding the reference with
        ALLOW_DEPRECATED_DECLARATIONS_* macros.

        Attempting to address the build failure by unconditionally enabling
        the dark-mode code works for tvOS, but fails for watchOS due to lack

        Implement beginSimulatedSwipeInDirectionForTesting() and completeSimulatedSwipeInDirectionForTesting()
        in ViewGestureController for controlling the test swipes. Add functions in WebKitWebViewBase for calling
        them.

        Simulate the gesture by generating two scroll events: one to begin the gesture and one to complete it.

        I am unclear of the implications of that bug, but it is clear for this bug that it

        Handle NSProgress calling our cancellation handler on background threads (and calling it more than once).
        <rdar://problem/51392926> and https://bugs.webkit.org/show_bug.cgi?id=198945

        Reviewed by Alex Christensen.

        If you have a download in progress and quickly tap the button to cancel it multiple times, then:
            - NSProgress calls our cancellation handler on a non-main thread, which we can't handle.
            - They do it more than once, which is also bad.
            - They might even do it multiple times concurrently (on different background dispatch queues)
        
        Let's work around these.

        * NetworkProcess/Downloads/Download.cpp:
        (WebKit::Download::cancel): Double check we're on the main thread, and handle being called twice.

        * NetworkProcess/Downloads/cocoa/WKDownloadProgress.mm:
        (-[WKDownloadProgress performCancel]): Actually cancel the WebKit::Download if we still have one.
        (-[WKDownloadProgress progressCancelled]): Called when NSProgress calls the cancellation handler, no matter
          which thread it does it on. By leveraging std::call_once we handle multiple calls as well as being called
          concurrently from different threads. call_once punts the *actual* cancel operation off to the main thread.
        (-[WKDownloadProgress initWithDownloadTask:download:URL:sandboxExtension:]): The cancellation handler is
          now simply calling 'progressCancelled' on self, assuming the weak pointer for self is still valid.

        Do not insert a character for an unhandled key command that has a Command modifier.

        The namespace ID is coming straight from IPC so should not be trusted.
        Also, namespace IDs are added/removed based on web pages being created/deleted.

        that process with current ITP state if the Network Process crashes and is relaunched. This wasn't a
        problem in earlier releases because we tracked all ITP state in the UIProcess.

        This patch does the following:
        1. Add a new method to WKWebsiteDataStore to allow us to trigger statistics processing, which has the
           side effect of syncing ITP state persistently so that it will be available after bouncing the process.
        2. Adds a new test that sets a tracking domain, bounces the process, and confirms the state is still
           consistent.

        Tested by TestWebKitAPI.

        waitForNavigationToComplete may be called before WebPageProxy knows it's loading

        Reviewed by Joseph Pecoraro.

        There's a potential race in `WebAutomationSession::waitForNavigationToCompleteOnPage` when
        querying for the `WebPageProxy`'s loading state (via `PageLoadingState::isLoading`), in that
        a pending load may be committed _after_ the `WebAutomationSession` checks it's value. This
        makes the automation session think that it isn't loading, so it will continue running
        commands, which can lead to a JavaScript error ("Callback was not called before the unload
        event") as any injected scripts will be cleared by the impending navigation, leaving the
        script evaluation callbacks "dangling".

        Expose more information from `PageLoadState` about whether it thinks there _may_ be a
        navigation currently happening, which the `WebAutomationSession` can use to delay commands.

        In the best case, no navigations are "missed".

        In the worst case, the automation session will wait `pageLoadTimeout` before continuing.

        NetworkProcess currently instructs UIProcess whether a given WebProcess is doing upload.
        There is no guarantee though that the WebProcessProxy is still there when the IPC is arriving at UIProcess.
        Instead, let WebProcess handles its upload state and notify WebProcessPool about its state.
        Make sure WebProcessProxy unregisters itself in case of crash.
        In case of NetworkProcess crash, WebProcesses will see all their uploads fail
        and will notify automatically UIProcess to update their state.

        Since the processID given to WebProcessPool is coming from IPC, we cannot not trust it.
        Add early return in case of not finding a WebProcessProxy for WebProcessPool clear/set methods.

        This is a partial implementation:
        - inspector integration is not working.
        - some error cases are not well handled or are not producing the same error messages.
        - some features are not implemented (extensions, subprotocols, handshake authentication challenge, cookie handling...).

        Reviewed by Brian Weinstein.

        It's possible that an active session is aborted before the completion handler passed to
        platformShowPaymentUI() has executed. When that happens, m_state will be Idle even though we
        assert that it is Activating. Fix this by returning early in the platformShowPaymentUI()
        completion handler when m_state is Idle.

        It's not possible to write a layout test for this because MockPaymentCoordinator handles
        showing payment UI directly in the web process, so this code is not executed in layout
        tests. The assertion can be reproduced manually by loading
        https://w3c-test.org/payment-request/payment-is-showing.https.html and clicking the button.

        When there is no process pool, we store cookies set in memory with HashSet m_pendingCookies of WebsiteDataStore.

        HashSet does not contain duplicate Cookies that are completely identical, but it may contain Cookies that have 
        all the other properties identical other than value. This is not correct because Cookies with same name, domain
        and path should be treated as the same cookie. When a cookie is set via API, we should either insert the 
        cookie into m_pendingCookies if the cookie does not exist, or update the cookie value if it already exists.

        Note that we still use HashSet with CookieHash for m_pendingCookies because in cookie deletion, we only delete 
        cookie when there is a complete match. If some cookie from m_pendingCookies has all other properties the same as
        the cookie specified in the deletion function, but the value is different, it will not be removed.

        We now set a new allowsFastClicksEverywhere property on the WebPageProxy when the content mode changes, set to true
        when we're in desktop browsing mode. We now check on this property to opt into the fast clicks everywhere behavior.

        This patch had been reverted once because it yielded some regressions in existing tests, notably under
        fast/events/touch/ios/content-observation. This updated patch addresses this by ensuring the gesture recognizers
        used for double-tap-to-zoom are disabled in -[WKContentViewInteraction _didStartProvisionalLoadForMainFrame]
        to ensure that two tests dispatching a tap at the same location don't yield the recognition of a double-tap

        REGRESSION(r243094): [GTK][WPE] Stale content after restoring the web view session
        https://bugs.webkit.org/show_bug.cgi?id=198561

        Reviewed by Chris Dumez.

        This is another regression of delaying the web process launch until the first load. If the session is restored
        before anything has been loaded, which is the normal way, the RestoreSession message is just ignored and the
        state is sent to the WebPage on creation via creation parameters. The WebPage considers that restoring a session
        from creation parameters only happens when re-launching a process after a crash or in case of process swap. In
        those cases, the history item is not marked as restored from session. We need to ensure the session is restored
        in the web process from the IPC message handler, by launching the initial process before the session is
        restored.

        Crash using WKHTTPCookieStore when you use WKWebView and UIWebView in the same app
        https://bugs.webkit.org/show_bug.cgi?id=198622

        Reviewed by Chris Dumez.

        Today in a WWDC lab, I saw some crash reports from an app that mixed
        WKWebView and UIWebView. The proximate cause of the crash is that
        WKHTTPCookieStore queues a callOnMainThread function, and then
        UIWebView dequeues it on the WebThread.

        No test because this crash depends on mixing WKWebView and UIWebView and
        getting (un)lucky on the timing.
