        Copying content with shadow DOM doesn't copy any contents
        https://bugs.webkit.org/show_bug.cgi?id=157443

        Reviewed by Wenson Hsieh.

        This patch adds the support for copying and pasting content across shadow boundaries in HTML and plain text,
        which is enabled whenever selection across shadow boundaries is enabled.

        To do this, TextIterator now has a constructor which takes two Positions, and the node traversal code in
        StyledMarkupAccumulator has been abstracted via helper functions as done for TextIterator.

        When serializing a HTMl slot element, serialize it as a span with "display: contents" to make sure when
        the content is pasted into a shadow tree, it wouldn't affect the slot assignment of the shadow tree.

        GC can collect JS wrappers of nodes in the mutation records waiting to be delivered

        [macOS] Switching to discrete GPU should be done in the UI process
        https://bugs.webkit.org/show_bug.cgi?id=189361
        <rdar://problem/43949622>

        Reviewed by Simon Fraser.

        Based on an earlier patch by Per Arne Vollan.

        Due to the fact we can't talk to the Window Server, the Web Process can
        no longer muxing to the discrete GPU directly. Instead we have to get the
        UI Process to process the change. Do this by adding a new Chrome client
        called GPUClient, that will have implementations provided by both WebKit
        and legacy WebKit.

        Unfortunately this can't be tested by a regular WKTR since:
        - it requires specific hardware
        - swapping to/from the discrete GPU takes about 20 seconds
        - running concurrent tests could confuse the tests into thinking
          the wrong GPU is active

        Instead we'll write a specific test for this functionality and
        run it on a separate bot.

        Reviewed by Chris Dumez.

        Before the introduction of URLParser, it would indicate that we should assume the String
        is from a valid URL so we can skip canonicalization and just find the offsets inside the String
        to quickly create a URL.  It was a performance optimization that caused security issues when
        misused.  Since the introduction of URLParser, we have a fast path for all URL parsing, so
        right now it actually doesn't change any behavior.  It's just a relic of the past that complicates
        the URL class, making it harder to express which constructor to use and making it harder to move
        the class.

        When the line setting contains an optional alignment value, the cue is not rendered at the correct position,
        see https://w3c.github.io/webvtt/#webvtt-line-cue-setting. This patch does not implement correct handling of
        the line setting alignment values, it only makes sure parsing does not fail when the cue has line alignment

        [MSE][GStreamer] Add h264parse to accept MP4 without stss
        https://bugs.webkit.org/show_bug.cgi?id=190143

        Reviewed by Xabier Rodriguez-Calvar.

        The MP4 file used in this URL does not contain a stss (Sync Sample
        Box). In consequence, in acordance with the ISO BMFF spec, all samples
        are assumed to be sync frames... But in this case that is not true,
        it's just that the file is wrong (e.g. created with a buggy muxer).

        http://orange-opensource.github.io/hasplayer.js/1.2.0/player.html?url=http://playready.directtaps.net/smoothstreaming/SSWSS720H264/SuperSpeedway_720.ism/Manifest

        The way it works in other browsers is because instead of trusting the
        MP4 stss table, they rely on parsing the h264 frames. We can do that
        too.

        This patch also changes RELEASE_ASSERT() when creating the parsers
        to GLib criticals.

        [iOS] Special keys are misidentified in DOM keyboard events
        https://bugs.webkit.org/show_bug.cgi?id=189974

        Reviewed by Wenson Hsieh.

        This patch fixes two issues:
            1. Special keyboard keys would be misidentified in dispatched DOM keyboard events.
            2. DOM keypress events may not be dispatched for some special keys.

        UIKit uses special input strings to identify the Page Up, Page Down, Escape, Up Arrow, Down Arrow,
        Left Arrow, and Right Arrow keys. It also uses ASCII control characters to represent some other
        special keys, including Num Lock / Clear, Home, End, Forward Delete, and F1, ..., F24. We need
        to explicitly handle these special keyboard keys in order to be able to identify the key that
        was pressed as well as to correctly disambiguate a key down to know whether to dispatch a DOM
        keypress event for the key.

        Unlike UIKit, AppKit reserves Unicode Private Use Area (PUA) code points in 0xF700–0xF8FF to
        represent special keyboard keys. This makes it straightforward to disambiguate such keys using
        the input string of the keyboard event alone. To simplify the implementation for iOS
        we normalize the input string be AppKit compatible. See the explaination for WebCore::windowsKeyCodeForCharCode()
        below for more details on why this is done.

        These special char codes are generated by WebKit. WebKit uses the same special char codes
        as AppKit as a convenience instead of defining our own constants for the same purpose.
        Encoding the special UIKit input strings (e.g. up arrow) as distinct char codes allows us
        to use integer arithmetic and switch blocks to map characters to Windows virtual key
        codes as opposed to special cased branches to perform pointer or string comparisions.
        The latter would be necessary in Modern WebKit in order for key down events to be properly
        disambiguated to dispatch a DOM keypress event because pointers are not perserved, though
        what they point to is, when sending the WebEvent from UIProcess to the WebProcess and

        [MSE][GStreamer] Reset running time in PlaybackPipeline::flush()
        https://bugs.webkit.org/show_bug.cgi?id=190076

        Reviewed by Philippe Normand.

        Test: media/media-source/media-source-seek-redundant-append.html

        PlaybackPipeline::flush() is called when already enqueued frames are
        appended again. This may be caused by a quality change or just a
        redundant append. Either way, the pipeline has to be flushed and
        playback begin again, but without changing the player position by
        much.

        There are two kinds of time to consider here: stream time (i.e. the
        time of a frame as written in the file, e.g. a frame may have stream
        time 0:01:00), and running time (i.e. how much time since playback
        started should pass before the frame should be played, e.g. if we
        started playing at 0:00:59 that same frame would have a running time
        of just 1 second).

        Notice how running time depends on where and when playback starts.
        Running time can also be optionally resetted after a flush. (This is
        indeed done currently by most demuxers after a seek.)

        Instead of resetting running time, PlaybackPipeline used to modify the
        first GstSegment emitted after the flush. A GstSegment declares the
        mapping between stream time and running time for the following frames.
        There, PlaybackPipeline used to set `base` (the running time at which
        the segment starts) to the position reported by a position query
        (which is stream time).

        This, of course, only worked when playback (or the last seek) started
        at stream time 0:00:00, since that's the only case where running time
        equals stream time. In other cases delays as long as the difference
        between these timelines would appear. This is demonstrated in the
        attached test, where seeks and appends are made in such an order that
        the difference is more than 5 minutes, making the playback stall for
        >5 minutes before playing 1 second of audio.

        This patch fixes the problem by resetting running time with the flush
        and not modifying GstSegment.base anymore (it will be left as zero,
        which is now correct since the running time has been reset).

        Use Position instead of Range in createMarkupInternal
        https://bugs.webkit.org/show_bug.cgi?id=190107

        Reviewed by Darin Adler.

        Use two Position's indicating start and end instead of Range in createMarkupInternal and StylizedMarkupAccumulator
        in order to support copy & paste across shadow boundaries in the bug 157443. This patch also removes the use of
        Range in MarkupAccumulator since all uses of range is via StylizedMarkupAccumulator.

        Also renamed createMarkupInternal to serializePreservingVisualAppearanceInternal to match the rename in r236612.

        (WebCore::StyledMarkupAccumulator::appendText): Use textContentRespectingRange in the case annotation is disabled
        instead of calling to MarkupAccumulator::appendText, which no longer respects boundary offsets.

        (WebCore::StyledMarkupAccumulator::renderedTextRespectingRange): Renamed from renderedText. Updated to respect
        boundary offsets defined by m_start and m_end Positions instead of m_range Range.

        (WebCore::StyledMarkupAccumulator::textContentRespectingRange): Renamed from stringValueForRange. Ditto.

        (WebCore::StyledMarkupAccumulator::serializeNodes): Now computes startNode and pastEnd nodes from start and end
        Positions. Note that the end position is always the next node in the tree order  for a character node
        and computeNodeAfterPosition returns nullptr for a character data.

        (WebCore::highestAncestorToWrapMarkup): Now takes two positions instead of a range.

        Specifically, gradients displayed at an angle (ie. 45 degrees) are rendered
        as if they are vertical when the body tag containing the gradient
        has a height of 0. Other browsers do not render under these circumstances,
        so WebKit was modified to follow in suit. The problem was due to layout sizes for
        fill tiles being calculated with a minimum height of 1px. A simple change of the
        minimum height and width to 0px was enough to bring about the desired behavior.

        RenderLayer::removeOnlyThisLayer() should not call updateLayerPositions()
        https://bugs.webkit.org/show_bug.cgi?id=190093

        Reviewed by Dean Jackson and Zalan Bujtas.
        
        It's wrong for RenderLayer::removeOnlyThisLayer() to call updateLayerPositions(),
        because this is called at style update time, and layout will be stale.
        
        It was added (see webkit.org/b/25252) so that opacity changes, which can destroy layers, correctly update
        descendants. However, RenderStyle::changeRequiresLayout() checks for opacity <=> no opacity
        changes and triggers layout accordingly, which will result in a full post-layout
        updateLayerPositions().
        
        This also revealed that changes to the "isolate" property fail to trigger any kind of style recalc or layout;
        we need it to trigger layout (for now) because it affects z-order.

        Covered by existing tests.

        Refactoring: eliminate raw pointer usage in Fullscreen code
        https://bugs.webkit.org/show_bug.cgi?id=188747
        <rdar://problem/43541164>

        Reviewed by Alex Christensen.

        Two sources of raw pointers in the Fullscreen code:
        - Model classes (PlaybackSessionModel and VideoFullscreenModel) aren't ref-able, so
          they are passed around as raw references.
        - Observer classes (PlaybackSessionModelClient and VideoFullscreenModelClient, and
          VideoFullscreenChangeObserver) are also passed around as raw pointers, but shouldn't
          be ref-able.

        Make Model classes ref-able by adding ref() and deref() which call virtual refModel and
        derefModel methods, overridden by implementing subclasses. Make every concrete observer
        inherit from CanMakeWeakPtr, and every registration method take WeakPtr wrappers around
        the client interface.

        Since every Interface class now holds a strong reference to its Model classes, and each
        Model class holds a weak reference to all its clients, no explicit invalidate() method
        is necessary.

        Notes:

        - Since the weak pointer methods need to be able to downcast to the abstract base class,
          observers need to inherit publically (rather than privately) from those base classes.
        - Media element Models should compose EventListener rather than inheriting from it, since
          EventListener has its own RefCount.
        - WeakPtrs can't be held in HashSets (because they change value, and therefore hash, when
          their underlying object is destroyed), so clients should be stored in a Vector instead.
        - Interfaces should be given all required Refs at creation time, so that they can store
          those parameters as Refs instead of RefPtrs.

        Simplify StyledMarkupAccumulator::traverseNodesForSerialization
        https://bugs.webkit.org/show_bug.cgi?id=190073

        Reviewed by Antti Koivisto.

        Simplified the range traversal algorithm in traverseNodesForSerialization as it was too complicated
        to support shadow DOM for copy and paste.

        Instead of using NodeTraversal::next to traverse past ancestors and then figuring out which ancestor
        must be closed or to wrap the existing markup with, new code collects the list of ancestors as we
        traverse out of them.

        Also extracted lambdas for generating markup and deciding whether to skip a node as well as keeping
        track of the depth of the current markup. This further reduces the code complexity of the actual
        node traversal algorithm. Keeping track of the depth allows us to now generate ancestor elements'
        closing tags without keeping a stack of ancestor nodes we opened at all times.

        because their implementations are identical.

        Note that offsetInCharacters() sounds like a function which returns some kind of an offset
        but it doesn't. It returns true when called on a CharacterData and false elsewhere.

        Refactoring: eliminate raw pointer usage in Fullscreen code
        https://bugs.webkit.org/show_bug.cgi?id=188747
        <rdar://problem/43541164>

        Reviewed by Alex Christensen.

        Two sources of raw pointers in the Fullscreen code:
        - Model classes (PlaybackSessionModel and VideoFullscreenModel) aren't ref-able, so
          they are passed around as raw references.
        - Observer classes (PlaybackSessionModelClient and VideoFullscreenModelClient, and
          VideoFullscreenChangeObserver) are also passed around as raw pointers, but shouldn't
          be ref-able.

        Make Model classes ref-able by adding ref() and deref() which call virtual refModel and
        derefModel methods, overridden by implementing subclasses. Make every concrete observer
        inherit from CanMakeWeakPtr, and every registration method take WeakPtr wrappers around
        the client interface.

        Since every Interface class now holds a strong reference to its Model classes, and each
        Model class holds a weak reference to all its clients, no explicit invalidate() method
        is necessary.

        Notes:

        - Since the weak pointer methods need to be able to downcast to the abstract base class,
          observers need to inherit publically (rather than privately) from those base classes.
        - Media element Models should compose EventListener rather than inheriting from it, since
          EventListener has its own RefCount.
        - WeakPtrs can't be held in HashSets (because they change value, and therefore hash, when
          their underlying object is destroyed), so clients should be stored in a Vector instead.
        - Interfaces should be given all required Refs at creation time, so that they can store
          those parameters as Refs instead of RefPtrs.

        Drop iOS specific quirk in SettingsBase::scriptEnabledChanged() that would dirty style after the
        "JavaScriptEnabled" setting's state is toggled. I do not see a good reason to do this given that
        scripts would not get executed until a reload.

        If we find out after dropping this that this is actually useful for some reason, then we can
        always bring it back and consider making this non-iOS specific, as well as documenting why this
        it is needed.

        MediaPlayer should have mediaPlayerWaitingForKeyChanged() / bool waitingForKey() accessor

        Reviewed by Eric Carlson.

        In order to implement the "Resume Playback" section of EME, part 4, we need to be able
        to query whether the MediaPlayer is still waiting for a key after attemptToDecrypt()
        has been called. Currently this involves no behavioral changes, as all modern EME ports
        will still just notify the media element that they no longer need keys after one has
        been added, but future ports may be able to wait for multiple keys before reporting
        that it is no longer waiting for keys.

        This bug reproduced when unordered appends were made. For instance, if

        would be wrongly discarded from the decode queue.

        Later the application could append [10, 20) and the gap at [20, 21)
        would persist in the decode queue, even if the frame remained in the
        track buffer table.

        URLParser should use TextEncoding through an abstract class
        https://bugs.webkit.org/show_bug.cgi?id=190027

        Reviewed by Andy Estes.

        URLParser uses TextEncoding for one call to encode, which is only used for encoding the query of URLs in documents with non-UTF encodings.
        There are 3 call sites that specify the TextEncoding to use from the Document, and even those call sites use a UTF encoding most of the time.
        All other URL parsing is done using a well-optimized path which assumes UTF-8 encoding and uses macros from ICU headers, not a TextEncoding.
        Moving the logic in this way breaks URL and URLParser's dependency on TextEncoding, which makes it possible to use in a lower-level project
        without also moving TextEncoding, TextCodec, TextCodecICU, ThreadGlobalData, and the rest of WebCore and JavaScriptCore.

        There is no observable change in behavior.  There is now one virtual function call in a code path in URLParser that is not performance-sensitive,
        and TextEncodings now have a vtable, which uses a few more bytes of memory total for WebKit.

        [Apple Pay] Support granular errors in PaymentDetailsUpdate
        https://bugs.webkit.org/show_bug.cgi?id=189938

        Reviewed by Youenn Fablet.

        Implemented the shippingAddressErrors, payerErrors, and paymentMethodErrors properties on
        PaymentDetailsUpdate, as specified in the Payment Request API W3C Editor's Draft of
        26 September 2018.

        When these errors are specified in a PaymentDetailsUpdate, map them to PaymentErrors. For
        shippingAddressErrors and payerErrors, we use the "shippingContactInvalid" code and a
        contact field that matches the shippingAddressError or payerError property specified.

        For paymentMethodErrors, we interpret this as a sequence of ApplePayErrors, which are
        converted to PaymentErrors as in Apple Pay JS.

        [MSE][GStreamer] Use sentinel buffer to detect end of append
        https://bugs.webkit.org/show_bug.cgi?id=189924

        Reviewed by Philippe Normand.

        This patch introduces a new mechanism to detect when an append has
        been consumed completely by the demuxer. It takes advantage of the
        fact that buffer pushing is synchronous: both the appsrc and the
        demuxer live in the same streaming thread. When appsrc pushes a
        buffer, it's actually making a qtdemux function call (it calls its
        "chain" function). The demuxer will return from that call when it has
        finished processing that buffer; only then the control returns to
        appsrc, that can push the next buffer.

        By pushing an additional buffer and capturing it in a probe we can
        detect reliably when the previous buffer has been processed.
        Because the pipeline only has one thread, at this point no more frames
        can arrive to the appsink.

        This replaces the old method of detecting end of append which relied
        on the `need-data` event, which is more difficult to handle correctly
        because it fires whenever the appsrc is empty (or below a given
        level), which also happens when a buffer has not been pushed yet or
        in response to a flush.

        Reviewed by Antti Koivisto and Wenson Hsieh.

        This patch adds the basic support for selecting content across shadow DOM boundaries to VisibleSelection,
        which is enough to allow users to select content across shadow DOM boundaries via a mouse drag.

        This is the first step in allowing users to select, copy and paste content across shadow DOM boundaries,
        which is a serious user experience regression right now. The new behavior is disabled by default under
        an interal debug feature flag: selectionAcrossShadowBoundariesEnabled.

        Like Chrome, we are not going to support selecting editable content across shadow DOM boundaries since
        we'd have to generalize every editing commands to make that work, and there aren't any HTML editors that
        use shadow DOM boundaries within an editable region yet. For simplicity, we also don't support extending
        a selection out of a shadow root which resides inside an editing region.

        The keyboard based navigation & manipulation of selection as well as allowing copy & paste of content
        across shadow DOM boundaries will be implemented by separate patches. DOMSelection will not expose this new
        behavior either. This is tracked in the spec as https://github.com/w3c/webcomponents/issues/79

        an extension of a selection starting in a shadow tree inside a non-editable region inside an editable region

        [Web Animations] Ensure renderers with accelerated animations have layers
        https://bugs.webkit.org/show_bug.cgi?id=189990

        Reviewed by Zalan Bujtas.

        We have done some work already in webkit.org/b/189784 to prevent never-ending calls to DocumentTimeline::updateAnimations(). This was due to
        the change made for webkit.org/b/186930 where we queued calls to updateAnimations() in KeyframeEffectReadOnly::applyPendingAcceleratedActions()
        while we were waiting for a renderer with a layer backing for a given animation target. Instead of doing this, we now ensure renderers always
        have a layer when they have an accelerated animation applied.

        No new tests, this is already covered by webanimations/accelerated-animation-with-delay.html and webanimations/opacity-animation-yields-compositing-span.html
        which respectively check that we can apply an accelerated animation to a non-positioned block and an inline element.

        [WebAuthN] Make AuthenticatorManager
        https://bugs.webkit.org/show_bug.cgi?id=189279
        <rdar://problem/44116792>

        Reviewed by Chris Dumez.

        This patch does the following things in WebCore in order to support AuthenticatorManager:
        1) It separates AuthenticatorTransport from PublicKeyCredentialDescriptor such that the enum
        can be queried from WebKit directly.
        2) It adds AuthenticatorAttachment to PublicKeyCredentialCreationOptions such that relying parties
        could express their interests in cross platform authenticators.
        3) It enhances IPC encoder/decoder of a few such that Vectors and empty objects can be correctly coded.
        4) It moves the LocalAuthenticator implementation to WebKit to better integrate with AuthenticatorManager.
        5) It moves linking to LocalAuthentication.framework to WebKit as well.
        6) It temporarily bans old mock test mechanism in Internals so we could enable the new mock test mechanism in
        WebKitTestRunner which we will have a better coverage of codes in UI Process. Those tests will be either
        removed or ported to the new mechanism in Bug 189283.
        7) It also removes "using namespace WebCore" from the top namespace in some .mm files as they are reordered
        to where they could introduce name confusions.

        Clean up code around RenderLayer's "has accelerated scrolling" functions

        which are hard to keep in your head. Removed usesAcceleratedScrolling() since it just returns hasTouchScrollableOverflow().
        Renamed hasAcceleratedTouchScrolling() to canUseAcceleratedTouchScrolling() to indicate that it just looks at style,
        not whether layout has given the layer scrollable overflow yet. Tidy up some #ifdefs.
        
        usesCompositedScrolling() and usesAsyncScrolling() are ScrollableArea overrides, and
        look at backing layers, so require that compositing has run already. Note this in comments.

        Cap lifetime of persistent cookies created client-side through document.cookie
        https://bugs.webkit.org/show_bug.cgi?id=189933

        Reviewed by Chris Dumez.

        Test: http/tests/cookies/capped-lifetime-for-cookie-set-in-js.html

        As pointed out in https://github.com/mikewest/http-state-tokens:

        1) Cookies are available to JavaScript by default via document.cookie, which
        enables a smooth upgrade from one-time XSS to theft of persistent credentials
        and also makes cookies available to Spectre-like attacks on memory.

        2) Though the HttpOnly attribute was introduced well over a decade ago, only
        ~8.31% of Set-Cookie operations use it today (stats from Chrome). We need
        developer incentives to put proper protections in place.

        3) The median (uncompressed) Cookie request header is 409 bytes, while the 90th
        percentile is 1,589 bytes, the 95th 2,549 bytes, the 99th 4,601 bytes, and
        ~0.1% of Cookie headers are over 10kB (stats from Chrome). This is bad for load
        performance.

        In addition to this, third-party scripts running in first-party contexts can
        read user data through document.cookie and even store cross-site tracking data
        in them.

        Authentication cookies should be HttpOnly and thus not be affected by
        restrictions to document.cookie. Cookies that persist for a long time should
        be Secure, HttpOnly, and SameSite to provide good security and privacy.

        By capping the lifetime of persistent cookies set through document.cookie we
        embark on a journey towards better cookie management on the web.
