                Widget::setFrameRect(), through WebHTMLView layout, could trigger a style recalc, which in turn
                could initiate an onBeforeLoad callback.
                If javascript happens to destroy the current iframe in the onBeforeLoad callback, we lose the descendant
                render tree, including the child FrameView (the iframe element's view). However the RenderIFrame
                object stays protected until after the layout is done. (see protectRenderWidgetUntilLayoutIsDone())

                Climbing back on the callstack, we need to make sure that
                1. the root widget of the descendant render tree (FrameView) stays valid as long as it is needed.
                2. RenderFrameBase::layoutWithFlattening() can handle the case when the associated widget (child FrameView) is set to nullptr.
                (see RenderWidget::willBeDestroyed() -> setWidget(nullptr))

                (and later, when layout is finished this (RenderIFrame) object gets destroyed too.)

            Various assertion failures occur when executing script in the midst of DOM insertion
            https://bugs.webkit.org/show_bug.cgi?id=132482

            Reviewed by Darin Adler.

            Prior to this change, when an element containing a <script> child was inserted into a document, the script was
            executed in ScriptElement::insertedInto(). That script can access nodes that follow it in the newly-inserted
            hierarchy but are not yet fully inserted, leading to at least the following problems:

                - The script could remove a node that is not yet marked as in the document.
                - The script could remove a named <map> that has yet to be added to TreeScope::m_imageMapsByName.
                - The script could remove a form control that has yet to be added to FormController::m_formElementsWithState.

            These scenarios all result in assertion failures. This change ensures that each node in the newly-inserted
            hierarchy is fully inserted before executing any scripts.

            REGRESSION(169105): CSS Regions: renderer returns wrong selection root when it is inside a column flow.

            This patch ensures that RenderObject::selectionRoot() handles column flows properly while searching for the associated
            selection root.
            When the renderer is inside a column flow and the column flow is part of a named flow, we stop
            traversing the ancestor chain, searching for the selection root, when we reach the column flow.
            Since the column flow is not a selection root, we mistakenly fall back to the RenderView as selection root.
            Instead, we should check if the column is inside a named flow and return the selection root accordingly.
            Returning the wrong selection root confuses RenderView::splitSelectionBetweenSubtrees() logic and this particular
            RenderObject could end up in multiple selection trees.

            Test: TestWebKitAPI/Tests/WebKit2Cocoa/ProvisionalURLChange.mm

            In some cases, trying to navigate to an invalid URL results in navigation to about:blank.
            When the about:blank load is committed, the UI process still thinks that the provisional
            URL is the original, invalid URL, and updates its state to reflect that that’s the URL that
            has been committed.

            The provisional URL changes (1) when a provisional load begins, (2) when a server redirect
            happens, (3) when the client changes the request in willSendRequest, and (4) in this
            about:blank case. For (1) and (2), there are frame loader client callbacks. (3) is client-
            initiated. So this patch addresses (4).

                Reviewed by Simon Fraser.

                This patch ensures that the render tree associated with the document on which
                the hit-test is initiated does not get laid out, unless it was directly mutated prior to the hittest.

                Hit-test requirements:
                1. A clean the render tree before hit-testing gets propagated to the renderers.
                Document::updateLayout() ensures it by calling both updateStyleIfNeeded() and layout() not only on the current tree, but also
                on the ancestors if needed.

                2. No render tree mutation while hit-testing the renderers.

                When an iframe is being hit-tested, this hit-test could bubble down to the child frame's render view.
                In order to ensure #1, we call Document::updateLayout() on the current (subframe) document.
                If updateStyleIfNeeded() mutates the render tree, we mark it dirty for layout(). However frame flattening also
                marks the parent renderer (RenderIFrame) dirty.
                While calling layout() to clean the current render tree, we end up laying out the parent tree too.
                Laying out the parent tree could end up destroying the inline tree context from where the
                hittest just bubbled down. (InlineFlowBox -> RenderWidget -> RenderView).

                This patch protects the render tree from such unintentional inline tree mutation during hittesting.
                After the initial layout we set a layout disallow flag on the frame view to defer subsequent layouts.
                This patch only changes behavior when frame flattening is enabled, but in future we may always want to enable this.

                WebKit uses some strings which contain the lower 8-bits of UTF-16 (thereby saving space). However,
                ICU doesn't understand this encoding. When we want to use ICU functions with strings in this encoding,
                we create a UTextProvider which converts our encoded strings to UTF-16 for ICU, one chunk at a time.
                This object contains a vtable which we populate to perform the conversion.

                The WebKit function which actually returns the UTF-16 chunks has two relevant arguments: an index into
                the encoded string which ICU is requesting, and a direction from that index which ICU is interested
                in. This function populates a "chunk" which is characterized by a pointer to a buffer, the length of
                the populated data in the buffer, and an offset into the chunk which represents the index that the
                requested character was put into.

                When ICU requests data going backward, we fill in the chunk accordingly, with the requested character
                all the way at the end. We then set the offset equal to the length of the buffer. However, this length
                value is stale from the previous time the function ran. Therefore, ICU was reading the wrong index in
                the chunk when expecting the requested character.

                Regression(r180020): Web Inspector crashes on pages that have a stylesheet with an invalid MIME type

                After r180020, we are stricter and no longer accept CSS resources that
                are not served with a CSS MIME type. Showing Web inspector on a page
                with such bad resource would crash because
                InspectorPageAgent::cachedResourceContent() would return true but
                the result String would be null. This null String would then later
                be passed to the Yarr interpreter and crash on a String::is8Bit()
                call.

                cachedResourceContent() calls CachedCSSStyleSheet::sheetText(). Before
                r180020, it would return the text, even if the MIME type was incorrect.
                However, this is no longer the case and we now need to make sure that
                cachedResourceContent() returns false if sheetText() returns a null
                String.

                Make scripts that run in an isolated world be subject to the Content Security Policy (CSP) of the page
                and exempt features implemented using a user agent shadow DOM. As a side effect of this change,
                Safari Content Extensions will respect the CSP policy of the page when loading subresources (e.g. an image).

            Make sure Node::insertedInto() gets called on the inserted node and its
            descendants after its insertion into the tree but *before*
            ContainerNode::childrenChanged() is called on the parent node. This is
            needed so that the descendants know they've been inserted into the tree
            (and their InDocumentFlag flag gets set) before the parent node does
            anything with them in childrenChanged().

            In the case of <rdar://problem/16798440>, executing HTMLScriptElement's
            childrenChanged() after appending a child to a script element was causing
            the script to be executed. The script would call getElementBy() which
            would traverse the DOM tree and find a matching Element in the newly
            inserted subtree. However, the matching Element's InDocumentFlag flag was
            not set yet because the element's insertedInto() method has not been called
            yet at this point. This would cause us to hit an assertion as
            DocumentOrderedMap::getElementById() is only supposed to return elements
            that are in a Document.

                This patch ensures that we don't adjust the selection unless the visual selection still matches this subtree root.

                When multiple selection roots are present we need to ensure that a RenderObject
                only shows up in one of them.
                RenderView::splitSelectionBetweenSubtrees(), as the name implies, splits the
                selection and sets the selection range (start/end) on each selection root.
                However, SelectionSubtreeRoot::adjustForVisibleSelection() later recomputes the range
                based on visible selection and that could end up collecting renderers as selection start/end
                from another selection subtree.
                RenderObject's holds the last selection state (RenderObject::setSelectionState).
                If we set a renderer first as "on selection border" and later "inside" using multiple selection roots,
                we can't clean up selections properly when this object gets destroyed.
                One of the roots ends up with a dangling RenderObject pointer.

                This patch ensures when an overhanging float renderer is destroyed,
                all the sibling containers' floating object set(m_floatingObjects) gets properly cleaned up.

                When an overhanging float is present, we cache the renderer on the parent and on the affected
                sibling containers too. (RenderBlockFlow::m_floatingObjects) These caches(sets) get cleared and repopulated
                during ::layout(). In order to have a float renderer removed from a set, a layout needs to be initiated on the container.
                This is normally done through RenderBlockFlow::markSiblingsWithFloatsForLayout() and RenderBlockFlow::markAllDescendantsWithFloatsForLayout().
                However, when the float container's parent's writing direction changes (and we promote the children containers to new formatting contexts),
                the layout propagation through siblings does not work anymore.

                The avoidsFloats() check in RenderBlockFlow::markSiblingsWithFloatsForLayout() has very little performance gain, but it prevents us
                from propagating layout to siblings when certain properties of the parent container changes.

            After r181656, all requestAnimationFrame was falling back to timers, and not
            using the platform's DisplayRefreshMonitor, because of a Nullopt vs nullptr
            fumble. As a result, GraphicsLayerUpdater (which updates tiled layers during
            animations) was failing to do any updates.

            Replace this confusing Optional<> code with simpler code that just forces the
            clients to make a DisplayRefreshMonitor if they can, first asking
            ChromeClient, and then falling back to createDefaultDisplayRefreshMonitor().

            Make lots of things into references, and use C++11 initialization in some places.

            In some cases (like the new test), we can end up trying to start
            requestAnimationFrame on a Document that has no Page. Most paths null-checked
            the Page and did the right thing, but one failed to do so. In addition,
            the current fallback (when Page is null) can result in us constructing
            the wrong kind of DisplayRefreshMonitor, which could lead to trouble
            down the road when it's reused. Instead, just completely avoid making a
            DisplayRefreshMonitor in the null-page case.

            If ChromeClient was unreachable for some reason, we'll get back an engaged

            If instead the client returns a disengaged Nullopt, we'll interpret that as
            "construct the default type", which falls back on the platform #ifdefs to

            REGRESSION (r181656): Animated tiled layers are missing content
            https://bugs.webkit.org/show_bug.cgi?id=143911
            rdar://problem/20596328

            Reviewed by Darin Adler.

            After r181656, all requestAnimationFrame was falling back to timers, and not
            using the platform's DisplayRefreshMonitor, because of a Nullopt vs nullptr
            fumble. As a result, GraphicsLayerUpdater (which updates tiled layers during
            animations) was failing to do any updates.

            Replace this confusing Optional<> code with simpler code that just forces the
            clients to make a DisplayRefreshMonitor if they can, first asking
            ChromeClient, and then falling back to createDefaultDisplayRefreshMonitor().

            Make lots of things into references, and use C++11 initialization in some places.

            Add Internals API to allow a test to get the number of layer flushes that have
            occurred.

            Add another assertion to help track down crash in
            DocumentLoader::stopLoadingForPolicyChange().

            The trace seems to hint that frameLoader() returns null when
            stopLoadingForPolicyChange() is called. frameLoader() can only return
            null after DocumentLoader::detachFromFrame() has been called.
            Also, stopLoadingForPolicyChange() here is called from the
            DocumentLoader::continueAfterContentPolicy() policy callback which
            requires m_waitingForContentPolicy to be true. Therefore, we should
            assert that m_waitingForContentPolicy is false when m_frame is cleared
            in DocumentLoader::detachFromFrame().

            [MSE][EME][Mac] Calling close on a MediaKeysSession will cause many decoding errors to be emitted
            https://bugs.webkit.org/show_bug.cgi?id=142285

            Reviewed by Eric Carlson.

            When a MediaKeySession (backed by CDMSessionMediaSourceAVFObjC) is closed and the
            underlying AVStreamSession is invalidated, the decryption context for in-flight
            CMSampleBuffers is also invalidated, and the AVSampleBufferDisplayLayer will issue
            one error for each enqueued and un-displayed sample in its image-queue. -flush-ing
            the AVSampleBufferDisplayLayer is not enough, as the flush only takes effect
            asynchronously the next time the layer needs new samples.

            Add a workaround until framework-level support lands to fully flush enqueued and
            encrypted frames.

            When the CDMSessionMediaSOurceAVFObjC object recieves an error from the layer,
            check to see if the session has been stopped. If so, and if the error in question is
            one that indicates that the samples decryption context has been invalidated, suppress
            the error and instruct the sender to suppress the error as well. This workaround will
            be removed once real support for synchronous flushing lands in <rdar://problem/20027434.>

            Still, we'll make our best effort to flush undisplayed frames when our CDM session is
            invalidated. Move away from std::map and instead use HashMap to store the set of 
            AVSampleBufferAudioRenderers. This allows us to use C++11 style loops against just
            the HashMap's set of values.

            The function for deciding whether the logical height of the columns was
            known was checking for a zero computedColumnHeight. However, a column set
            can legitimately compute a zero column height, and with the fix to examine
            the layout state, this bug was exposed.

            The fix is to add a new variable that caches whether or not the column height
            has been computed, so that even if it computes to zero, we aren't fooled.

        customize the rules that ICU's line breaking algorithm uses (especially for CJK text);
        however, ubrk_openRules() currently parses its input string to create a DFA and is

            Justified ruby can cause lines to grow beyond their container
            https://bugs.webkit.org/show_bug.cgi?id=141732

            Reviewed by David Hyatt.

            After we re-layout RenderRubyRuns, this can change the environment upon which
            ruby's overhang calculation is sensitive to. Before this patch, we would recalculate
            the overhang after the RenderRubyRun gets relaid out. However, doing such causes the
            effective width of the RenderRubyRun to change, which causes out subsequent
            justification calculations to be off.

            Therefore, we have a cycle; the amount of ruby overhang can change the justification
            in a line, and the layout of the line affects the ruby overhang calculation. Instead
            of performing a layout in a loop until it converges, this patch simply observes that
            having a flush right edge is more valuable than having a perfectly correct overhang.
            It therefore simply removes the secondary overhang calculation.

            That could cause FrameView::updateLayoutAndStyleIfNeededRecursive() to fail to 
            leave all the frames in a clean state. Later on, we could enter hit testing,
            which calls document().updateLayout() on each frame's document. Document::updateLayout()
            does layout on all ancestor documents, so in the middle of hit testing, we could
            layout a subframe (dirtying an ancestor frame), then layout another frame, which
            would forcing that ancestor to be laid out while we're hit testing it, thus
            corrupting the RenderLayer tree while it's being iterated over.
            
            Fix by having FrameView::updateLayoutAndStyleIfNeededRecursive() do a second
            layout after laying out subframes, which most of the time will be a no-op.
            
            Also add a stronger assertion, that this frame and all subframes are clean
            at the end of FrameView::updateLayoutAndStyleIfNeededRecursive() for the
            main frame.

            Various existing frames tests hit the new assertion if the code change is removed,
            so this is covered by existing tests.

            There's an expectation from clients that FrameView::updateLayoutAndStyleIfNeededRecursive()
            updates layout in all frames, but it uses the widget tree, so only hits frames
            that are parented via renderers (i.e. not display:none frames or their descendants).
            
            Moving towards a future where we remove Widgets, fix by adding a FrameTree 
            traversal function that only finds rendered frames (those with an ownerRenderer).

            [CSS Regions] Assertion failure and null dereference crash when using animations and regions

            Reviewed by Andrei Bucur.

            In some situations, for instance when an image has an attached animation, the style change caused by the animation
            triggers a geometry update for the backing store associated with the image's layer. This may occur before
            the layout for the image has finished.

            Moreover, if the image in such situation - having a composited layer - is displayed in a region,
            sicne the layout did not finish yet, the mappings between the layers of the elements collected in the named flow
            and the regions associated with the named flow are not updated and cannot be used.

            Therefore in those situations, we have to bail out early and use these mappings only after the layout has finished.

            This patch also changes RenderLayerBacking method updateAfterDescendents -> updateAfterDescendants.

            out a line. This patch also adds a field to RenderRubyBase which represents

            an expansion from a line might occur at the very beginning of a ruby base,

            layout time.

            are the same. The problem is <animateMotion> should not have an attribute to animate.
            If it does by fuzz or by mistake, then we assume the <animateMotion> and the <animate>
            animate the same attribute for the same element target. Therefore we schedule them in
            the same AnimationVector in SMILTimeContainer::schedule(). When we call
            SVGAnimateElementBase::calculateAnimatedValue() for an SVGAnimateColorElement and the
            resultElement is SVGAnimateMotionElement, we fail to cast it to SVGAnimateElementBase
            because SVGAnimateMotionElement is derived from SVGAnimationElement which is the base
            class of all animate elements including SVGAnimateElementBase.

            The fix is to nullify setting "attributeName" of an SVGAnimationElement. By doing so,
            "attributeName" and its value will be ignored from the <animateMotion> which is correct.

            Tests: svg/animations/animate-montion-invalid-attribute.svg.

            (WebCore::SVGAnimateElementBase::setAttributeName):
            Do not call SVGAnimationElement::setAttributeName() since SVGAnimationElement should
            not have an attribute to animate. We prevent this by bypassing the parent in the class 
            hierarchy: SVGAnimationElement and calling SVGSMILElement::setAttributeName() directly.

            Similar approach as https://codereview.chromium.org/679593004/

            This patch ensures that laying out a RenderQuote does not force a sibling RenderQuote's
            child renderer(RenderText) to be destroyed.
            BreakingContext holds a pointer to the next renderer on the line (BreakingContext::m_nextObject).
            While laying out the line, initiated by BreakingContext, placing the current renderer could end up destroying the "next" renderer.
            This happens when the pseudo after quotation mark(RenderQuote) becomes floated, the sibling <q>'s pseudo
            before text needs to be changed (from " to ') so that we don't end up with 2 sets of the same opening
            strings.
            The fix is to reuse the RenderTextFragment object instead of destroy/recreate it.

            The bug was caused by markAndReplaceFor not running the code to preserve the selection after
            text replacement only when smart quote is enabled. Furthermore, when smart link was disabled,
            we never applied smart quote due to the following condition at line 2502:

            if (!(shouldPerformReplacement || shouldCheckForCorrection || shouldMarkLink) || !doReplacement)
                continue;

            This condition prevented the code to apply smart quote from running when both continuous
            spellchecking, smart link, and text replacement are disabled.

            Fixed the bug by treating smart quotes and smart dashes like any other text replacement and set
            shouldPerformReplacement to true whenever either one of those text checking options are present.

            Smart link didn't have this issue due to the explicit check for shouldMarkLink.

            Smart dashes didn't suffer this problem either because dashes replacement happens only once
            the caret has moved past the dashes but his patch makes go through the same code path to preserve
            the selection as well for consistency.

            For breaking after a Ruby we do better. The Ruby run caches its prior characters
            and line layout is able to obtain them and use them when deciding whether or not
            to break. This means for the "after" side of a Ruby, we're able to behave the same
            as if no Ruby was used.

            For programmatic scrolls, AsyncScrollingCoordinator::requestScrollPositionUpdate()
            calls updateScrollPositionAfterAsyncScroll(), then dispatches the requested
            scroll position to the scrolling thread.

            Once the scrolling thread commits, it calls back to the main thread via
            scheduleUpdateScrollPositionAfterAsyncScroll(), which schedules a second
            call to updateScrollPositionAfterAsyncScroll() on a timer. That's a problem,
            because some other scroll may have happened in the meantime; when the timer
            fires, it can sometimes restore a stale scroll position.

            Fix by bailing early from scheduleUpdateScrollPositionAfterAsyncScroll()
            for programmatic scrolls, since we know that requestScrollPositionUpdate()
            already did the updateScrollPositionAfterAsyncScroll().

            Graphics corruption after Find on some pages

            Reviewed by Zalan Bujtas.

            After doing a Find on http://shop.outlier.cc/shop/retail/chino.html,
            garbage could appear on some parts of the page. This is caused by creating
            a compositing layer which is marked as opaque, yet failing to paint the entire
            layer contents.

            This was caused by a bug in RenderBox::computeBackgroundIsKnownToBeObscured()
            logic. On the page in question, doing a Find could cause overflow:hidden sections
            to get scrolled (since Find can reveal the selection by scrolling overflow).
            However, the render tree walking under RenderBox::foregroundIsKnownToBeOpaqueInRect()
            fails to take overflow scrolling into account, so gives the wrong answer
            in some content configurations. As a result, we'd think that the background
            is obscured, and never paint it.

            Conservative fix is to have isCandidateForOpaquenessTest() return false
            when the content has any non-zero scroll offset.

        The second fix was to stop destroying the placeholder. Since the placeholder can just have been inserted, you
        can't delete it, since otherwise code further up the stack will access the deleted object. For now, we just
        leak the placeholder.

        The third fix is to make sure the subtreeRoot is properly updated to be the new placeholder.

            [Apple] Use Accelerate framework to speed-up FEGaussianBlur

            <rdar://problem/18434594>

            Reviewed by Simon Fraser.

            Using Apple's Accelerate framework provides faster blurs
            than the parallel jobs approach, especially since r168577
            which started performing retina-accurate filters.

            Using Accelerate.framework to replace the existing box blur (what
            we use to approximate Gaussian blurs) gets about a 20% speedup on
            desktop class machines, but between a 2x-6x speedup on iOS hardware.
            Obviously this depends on the size of the content being blurred,
            but it is still good.

            The change is to intercept the platformApply function on
            FEGaussianBlur and send it off to Accelerate.

                   Rather than trying to find those places to clear out the cache, it's easier to just add the elements to the children
                   array everytime it's asked for. Since there's only ever 3 elements (web area + 2 scroll bars) this should not be a performance hit.

            RenderMathMLUnderOver adds spacing to the child operator indefinitely when resizing the window.
            https://bugs.webkit.org/show_bug.cgi?id=137330

            Reviewed by Darin Adler.

            The layout for the <mundercover> math object happens in two separate passes. The first pass runs
            the layout for the two children and then calculates the maximum child width.  It then sets the 
            stretch size for the math operator child.  And finally it runs the second layout pass by calling
            the base class layout() function. The base class function then runs the layout for the children
            rendering blocks.  In the operator child function computePreferredLogicalWidths(), the stretch 
            size is used to adjust the width (or the height) of the operator. Then it adds the leading and
            trailing spaces and the total will be the operator child width.

            When resizing or zooming the window, the render objects are just invalidated but marked as 'needs-
            Layout'.  The problem is happening because the stretch size of the math operator is not reset
            before running the layout.  The old logical width (or height) of the the math operator child which
            is equal to the stretch size plus the leading and trailing spaces for is compared with the glyph
            size if the old logical width ( or height) is larger, it is set to be the stretch size.  When it
            is used again because of invalidation, new leading and trailing spaces are included in the new
            logical width.  So with every zooming-in or out or window resizing, new leading and trailing 
            spaces are added to the logical width of the math operator child or the math <munderober> object.

            Ensure the stretch size of the math operator render object is reset before running its layout.
            Running the layout means either the page is just loaded or it's invalidated which means, no 
            layout stall data should be used.

            REGRESSION (r160806): CSS zoom property doesn't work on anything inside anchors.
            <https://webkit.org/b/135344>
            <rdar://problem/17759577>

            When DeprecatedStyleBuilder applies the CSS zoom property (ApplyPropertyZoom)
            it first resets the "effective zoom" by calling RenderStyle::setEffectiveZoom().

            This mechanism was not resistent to being called multiple times, due to the
            optimization in RenderStyle::setZoom() to avoid copy-on-writing the shared data
            when setting some property to the already-set value.

            The bug would happen in this sequence:

            ApplyPropertyZoom:
                - setEffectiveZoom(1);
                - setZoom(2); // this updates the effective zoom
            ApplyPropertyZoom:
                - setEffectiveZoom(1);
                - setZoom(2); // this doesn't update the effective zoom

            When we run the second setZoom(2); call, the RenderStyle's zoom value is 2
            already and we'll early return without updating the effective zoom.

            This change moves the updating of the effective zoom in setZoom() to take place
            before the early return due to overwriting with the same value.

            Note: the fact that we're apply the zoom property twice is an inefficiency that
            we should figure out a way to avoid in the future.

            and returns the ones from the AVPlayerLayer.

            Create and attach an AVPlayerItemVideoOutput after creating the AVPlayerItem, but before attaching
            the player item to the AVPlayer. This eliminates the reconfigure step which occurs after attaching
            a video output to an already attached AVPlayerItem.

            When creating the AVPlayerItemVideoOutput, pass in `nil` for the pixelBufferAttributes parameter.

            Instead of blocking waiting for output from the AVPlayerItemVideoOutput during creating, block and
            whait when asked to paint with the video output.

            When a frame is replaced, there were instances when it was not clearing its associated nodes in the accessibility text marker -> Node cache.
            This caused dead Nodes to be left in the cache which would eventually be accessed when the cache was cleaned out at a later time.

            To fix this we should be clearing out the cache in Document::prepareForDestruction, instead of Frame::disconnectOwnerElement.

            While working on this, it also exposed a problem where when a frame goes away, it doesn't inform its parent to update its children,
            which causes an ASSERT to be hit with this test as well.

            at the origin of the next column. However, if there is negative line
            spacing, the top portion of the text might actually be on top of the
            origin of the block. Therefore, the block wasn't being pushed down enough

            Reviewed by Mario Sanchez Prada.

            If a website has multiple nested tables that are not "accessibility" tables, the performance of accessibility slows to a crawl because:
              1) We are re-computing accessibilityIsIgnored many times.
                   As a solution, we can enable the isIgnoredCache when updating children.
              2) When asking if an object isTableCell, we'd go up the parent chain, asking each of those parents the same question, which exploded into calling this many times.
                  As a solution, I've changed our determination of isTableCell to instead check if the parent is an accessibiltyTable which should be much faster.

            No new functionality. Existing tests cover changes.

            When italics is specified on a font, and the font isn't coming from the cache, we ask
            the SimpleFontData to provide a non-synthetic-italic version of itself. Our current
            implementation doesn't preserve whether or not the SimpleFontData includes vertical
            glyphs (glyphs that are not rotated when drawn in the vertical writing mode), which
            determines which baseline we use to lay out the text. By passing "false" to
            the isTextOrientationFallback argument to SimpleFontData::create(), we preserve this
            hasVerticalGlyphs flag.

            This code is not yet being built and tested by our system. Appropriate
            tests will be activated when we enable the build.

            Most of this patch involves correcting some misuse of the AVFoundationCF API.
            1. It is never appropriate in AVCF to pass a null CFErrorRef; instead you must
               pass a CFErrorRef with error type kCFURLErrorUnknown.
            2. Because of the asynchronous way we handle the request/response, it is possible
               for AVCF to make two AVCF requests while negotiating the key exchange.

            Timer does not need to be a templated class; only it's constructors need to be templated.
            Remove the template specifier from Timer and add same to its two class method
            constructors. Replace the function pointer typedefs with using statements. Add a
            helper typedef which allows invalid combinations of TimerFiredClass and
            TimerFiredFunction to be caught early by the compiler, while still allowing
            valid combinations (such as when the caller specifies a function on a subclass of
            TimerFiredClass).

            [EME][Mac] Update to match new AVStreamSession API and requirements.
            https://bugs.webkit.org/show_bug.cgi?id=137923

            Reviewed by Eric Carlson.

            The session identifier has moved from AVStreamDataParser to -[AVStreamSession contentProtectionSessionIdentifier]
            and the property is no longer KVObservable. A new notification key has been added in place of KVO.

            Additionally, the requirements for using AVStreamDataParser with AVStreamSession have changed. It is now
            required that AVStreamDataParsers be added to an AVStreamSession before the 
            -streamSession:didProvideContentKeyRequestInitializationData:forTrackID delegate method is called. A
            -streamParserWillProvideContentKeyRequestInitializationData:forTrackID delegate has been added, and
            an AVStreamSession must be created and the AVStreamDataParser added to it during the scope of that delegate
            method.

            To facilitate this, the MediaPlayerPrivateMediaSourceAVFObjC object will lazily create and own a AVStreamSession
            object when requested. The SourceBufferPrivateAVFObjC object will listen for the -willProvide delegate call
            and will add its AVStreamDataParser to that AVStreamSession when called.

            The CDMSessionMediaSourceAVFObjC object is no longer responsible for creating the AVStreamSession, and because
            the session identifier has moved from many AVStreamDataParsers to a single AVStreamSession, the
            CDMSessionMediaSourceAVFObjCObserver class can become much simpler, as it only has to observe a single object.

            Update our forward declaration to match the API provided by AVStreamSession.

            secure-proof-of-key-release message after the client calls MediaKeySession.close().
            Because this call will now generate messages, which have to be responded to in order
            to remove those proofs from storage, do not clear the CDMSession from MediaKeySession
            after calling close().

            [EME][Mac] Refactor CDMPrivateMediaSourceAVFObjC to allow sessions to be created without being attached to an AVStreamDataParser.
            https://bugs.webkit.org/show_bug.cgi?id=136016

            Reviewed by Eric Carlson.

            The CDMPrivateMediaPlayer class will delegate creation of CDMSession instances to the current MediaPlayer. This
            of course requires the MediaKeys object owning the CDM to be attached to a HTMLMediaElement, and specifically to
            one with a valid src attribute or source node which has sucessfully begun loading. For certain CDM operations,
            it would be better if a given MediaKeys could create a session without actually being connected to a
            HTMLMediaElement (yet).

            To facilitate this for CDMSessionPrivateMediaSourceAVFObjC, add a new class, CDMPrivateMediaSourceAVFObjC, which
            is the primary factory for CDMSessionPrivateMediaSOurceAVFObjC. Disclaim responsibility for creating these sessions
            in MediaPlayerPrivateMediaSourceAVFObjC by not passing the "supportsKeySystem" method when registering itself.

            Add methods to CDMSessionPrivateMediaSourceAVFObjC to allow SourceBuffers to be added and removed from the session,
            to support adding the session to the HTMLMediaElement after the session has been created.

            Since MediaPlayerPrivate instance and  CDMSession instances must be able to communicate with one another, add a type()
            enum and virtual method to allow CDMSession instnaces to be distinguisted from (and casted to) one another.

            [MSE] Re-enqueue after a removeCodedFrames() only if the removed frames overlap what may have possibly been enqueued but undisplayed.

            Reviewed by Eric Carlson.

            When a client calls removeCodedFrames(), we must re-enqueue those ranges if the removed samples overlap with
            enqueued but possibly un-displayed samples. Otherwise, replacement samples may lead to decode errors as those
            new samples dependencies are not met. But if we re-enqueue too frequently, this may cause subtle but noticible
            display timing glitches, so only re-enqueue when removeCodedFrames have a possiblity of removing enqueued, but
            not yet displayed samples.

            During GraphicsLayer flushing, for tiled layers we can compute a visible rect using
            the current state of an animation, which is obtained via the AnimationController.
            If that animation was running in a subframe, AnimationController could use a stale
            beginAnimationUpdateTime since no-one called its beginAnimationUpdate(). That
            resulted in an incorrect computation of the visible rect, resulting in missing tiles.
            
            There are two parts to this fix. First, add an assertion that beginAnimationUpdateTime()
            is being called inside an animation update block. This required moving m_beginAnimationUpdateCount
            into AnimationControllerPrivate, and changes to endAnimationUpdate().
            
            The second is adding a AnimationUpdateBlock to getAnimatedStyleForRenderer(), which
            can be called outside of style resolution. We also need some in other API functions.
            
            Testing revealed that layout can call via layoutOverflowRectForPropagation(), suggesting
            that we should have an animation batch inside FrameView::layout(). In addition, a single
            resolveStyle/layout should use the same animationBeginTime, so we add a batch to 
            updateLayoutAndStyleIfNeededRecursive().
            
            Identical to the patch that was rolled out in r177269 with the addition of a 
            Ref<Frame> protector(m_frame) in AnimationControllerPrivate::animationTimerFired()
            that ensures that the AnimationControllerPrivate is kept alive for the scope of
            the AnimationPrivateUpdateBlock, when a transitionEnd event destroys an iframe.
            
            No test because it's timing-dependent. Existing tests exercise the new assertion.

        This patch fixes a crash when reloading the following URL:
        http://dnd.wizards.com/dungeons-and-dragons/story

        We were crashing in CachedRawResource::canReuse() because header.key
        would sometimes be a null String and we would call
        HashMap::get(nullString).

        The real issue was that header.key was null in the first place, which
        means that even though the HTTPHeaderMap iterator is valid, it->key
        is a null String, which should never happen. There was a bug in the
        HTTPHeaderMapConstIterator() constructor that would cause the
        iterator key/value pair to not get initialized if the HTTPHeaderMap
        contained *only* uncommon HTTP headers. This patch updates the
        constructor so that we fall back to updating the key/value from the
        uncommon header map, if we failed to initialized from the common
        header map (because it was empty).

            Serialization of MapData object provides unsafe access to internal types
            https://bugs.webkit.org/show_bug.cgi?id=138653

            Reviewed by Geoffrey Garen.

            We now keep the value portion of the key/value pair in MapData as a
            separate stack. This allows us to maintain the spec semantic of
            "atomic" serialisation of the key/value pair without retaining the
            use of a potentially invalid iterator.

        If a composited layer has no rendered content but a painting zero-opacity descendant

        When the opacity on such a child changes, we need to trigger a tree rebuild
        to force the backing store to come back (this could be optimized later).

            Reviewed by David Hyatt.
    
            Until we will support the multicolumn region functionality, a multicolumn element
            that also has flow-from style is not transformed into a region (https://bugs.webkit.org/show_bug.cgi?id=135153).
            However, when a multicolumn element with flow-from style dynamically loses
            its multicolumn style while keeping the flow-from style, we have to transform
            the element into a region by detaching and attaching the associated DOM node,
            in the same way we are proceeding when an element receives a different flow-from style.

            When we select all the content of document with named flows but without regions,
            the start and end points of selection is cached in RenderView. However, since
            the document has named flows, the selection is split between the subtrees. During the split,
            it is possible that the cached end-points of the original selection are not included
            in any of the resulting subtree selection and they are not marked accordingly.
            In order to process the selection clearing correctly, we have to take the original
            selection end-points into account.

            [Mac] Spending too much time mapping desired font families to available ones

            Reviewed by Darin Adler.
    
            While profiling the load of weather.com, I noticed that we are spending
            quite a bit of time trying to map the font family requested to a font
            that is available on the system. The process involves:
            1. Doing a linear search of all the installed font families and do a
               case-insensitive string comparison for each of them until we find a
               match,
            2. Then, if we don't find a match, do another linear search of the
               fonts' postscript names this time and do again a case-insensitive
               string comparison for each of them.
    
            This process is costly and the fonts requested by weather.com are not
            available, causing us to do 2 linear searches and a lot of string
            comparisons (accounting for ~2% of the WebProcess CPU time for the page
            load). As a result, we end up spending ~90ms in
            internalFontWithFamily() when loading weather.com.
    
            This patch introduces a cache for the mapping between desired font
            families and available font families. This cuts the time spent in
            internalFontWithFamily() in half (~45ms). The cache gets invalidated
            when fonts are installed / uninstalled on the system so we don't break
            that scenario. The cache is also limited in size to avoid using too
            much memory.
    
            No new tests, but manual testing making sure the cache gets invalidated
            when installing a font on the system.

            We are spending a lot of time loading fonts when loading weather.com:
            ~4.2% of WebProcess's cpu time in FontCache::getCachedFrontData().
            In particular, we are spending a lot of time doing font auto-activation
            because we don't have the Open Sans fonts installed and weather.com is
            trying to load those.
    
            Before this patch, we were doing font auto-activation ~250 times when
            loading weather.com, even though the site is loading ~10 distinct font
            families.
    
            This patch adds a cache of font families we already tried to
            auto-activate so that we don't try again. This results in ~10 font
            auto-activations when loading weather.com instead of 250. It reduces
            the amount of time spent in getCachedFrontData() to 62.6ms from 276ms

            While profiling the load of nytimes.com, I noticed that the site is
            accessing ~250 times document.cookie, just during page load. Accessing
            document.cookie is currently slow because we:
            - Call WebPlatformStrategies::cookiesForDOM() virtual function
            - Send a sync IPC message to the Network process to retrieve the
              cookies
                - The Network process gets the list of cookies from CFNetwork then
                  serializes the result to send it back to the WebProcess
            - We unserialize the cookies into an NSList of cookies
            - We filter-out the cookies that are 'httpOnly' and construct a new
              NSList of cookies
            - We create a WTF String out of the cookies NSList
    
            In the case of nytimes.com, it turns out that up to 100 calls to
            document.cookie() are made in the same event loop iteration. This patch
            thus caches / freezes the cookies until we return to the event
            loop so that consecutive calls to document.cookie() are extremely fast.
            Doing so seems to be sufficient to achieve a ~87% cache hit for
            nytimes.com page load.
    
            The cookies cache is invalidated whenever:
            - document.cookie is set
            - we return to the event loop
            - a network resource is loaded synchronously as it may cause cookies to

            RenderLayer::isVisuallyNonEmpty() would return true for replaced elements (e.g. images)
            with visibility:hidden, and for layers with a mask, and both would cause additional
            backing store in some cases.
            
            We can move the hasVisibleContent() to the top of the function, since visibility:hidden
            will always hide any content of this layer. The hasMask() check can also be removed;
            a mask can only mask content that is already visible; it never contributes additional
            pixels.

            HTMLPlugInElement::isUserObservable() is causing layout
            https://bugs.webkit.org/show_bug.cgi?id=137156

            Reviewed by Ryosuke Niwa.

            While profiling the page load of nytimes.com, I noticed that we were
            spending ~4-5% of cpu time in HTMLPlugInElement::isUserObservable().
            The reason is that the function calls pluginWidget(), which causes a
            layout update in HTMLObjectElement::renderWidgetForJSBindings(), to
            make sure the plugin is loaded and its renderer is created.

            HTMLPlugInElement::isUserObservable() shouldn't need to do a layout.
            This patch does the following to address the problem:
            - Rename renderWidgetForJSBindings() to renderWidgetLoadingPlugin()
              because this function is not always called from the JS Bindings
              nowadays. The new name makes it clearer that this will load the
              plugin if needed (to make sure the renderer is created, and by
              doing a layout).
            - Add a PluginLoadingPolicy argument to
              HTMLPlugInElement::pluginWidget() to let the caller control if the
              plugin should be loaded or not.
            - Update the call to pluginWidget() in isUserObservable() so that
              we do not attempt to load the plugin (thus not causing a layout).

            No new tests, no behavior change.

            Reviewed by Andreas Kling.

            When the minimum DOM timer interval changes, the Page updates all DOMTimers accordingly.
            Updating the fire/repeat interval on TimerBase requires a delta, but in
            DOMTimer::adjustMinimumTimerInterval we have the new requested interval. In the case of
            timers we can get the current interval to calculate the delta by calling repeatInterval(),
            but in the case of one-shot timers neither TimerBase nor DOMTimer have store the interval
            that was actually set for the timer (DOMTimer knows the original, unadjusted timer, but
            not the actual interval). The way this currently works is that when the minimum interval
            changes, Page calls adjustMinimumTimerInterval providing the previous minimum. If the
            timer is one-shot, then adjustMinimumTimerInterval will use this to compute the delta
            based on what the interval would have been.

            We can simplify & unify with the code to throttle interval timers when the nesting
            threshold is hit, by instead tracking the current timer interval as a member on DOMTimer &
            using this to compute the delta in all cases.

            Since this would happen after the 2 billionth timer fire this is unlikely,
            and consequences aren't severe (breaks throttling).

            This change has the following consequences.

                - m_nestingLevel saturates to its max value.
                - unnested timers are indicated by a nesting level of 0.
                - repeat timers update m_nestingLevel on every fire,
                  not just those that should have been throttled.

            The last point is subtle, but ultimately should be inconsequential. Timers
            whose requested timeout is less that the minimum interval will saturate quickly
            anyway; timers with an original interval greater than the minimum previously
            wouldn't have incremented m_nestingLevel, but doing so now doesn't hurt since
            they won't be throttled when they hit the threshold. This simplifies things
            conceptually a little & reduces the test performed on each timer fire.

            DOMTimer may be deleted during timer fire

            Consequentially ScheduledActions may also be deleted mid execution.
            This is fairly surprising & fragile, let's make this simpler.

            Currently DOMTimer instances are effectively owned by the ScriptExecutionContext.
            There is a 1-1 mapping between timers and contexts, all timers are help in a map
            on the context and if the context goes away all timers are deleted. Rather than
            being implemented in a straightforward fashion (a smart pointer type for the map
            value) this is currently implemented by having the timer objects listen for the
            context going away using contextDestroyed, and deleting themselves if so.

            Switch to using a smart pointer for values of m_timeouts in ScriptExecutionContext.
            By using a RefCounted object we can also extend the lifetime of the DOMTimer instance
            from within the DOMTimer::fired method, so the object is not destroyed while the
            member function is still on the stack.

            I noticed when profiling the ebay.com page load that isRunningAnimationOnRenderer()

            This patch introduces an isCSSAnimated flag on RenderElement to return early if
            there is no animation on the renderer, thus avoiding HashMap lookups. This reduces
            the number of HashMap lookups from ~4.7 millions to ~68k. On my machine, I see
            the following performance improvements:
            - isRunning*AnimationOnRenderer() / computeCompositingRequirements()

            When initiating a drag, the DragController checks whether the hit-tested element at a
            drag location is a child of the drag source, and bails if early if that is not the case.
            For a <video> element with controls, the hit-tested element is an element within the
            <video> element's Shadow DOM. Because the DragController uses a method which does not
            take Shadow DOM into account when determining a child-parent relationship, this test fails
            and all drag operations fail as well.

            For <video> elements only, when testing whether the drag source is an ancestor of the
            hit-tested element, use containsIncludingShadowDOM() instead of contains(). To ensure that
            the controls are still usable when a drag listener is active on a <video> element, mark
            the controls as a draggable element, but simply call preventDefault() in the controls'
            'dragstart' handler, ensuring the timeline and volume controls are themselves still draggable.

            Reviewed by Eric Carlson.

            YouTube only resizes its <video> content when entering fullscreen after receiving the "webkitfullscreenchange"
            event, which is fired once the animation to enter fullscreen completes. This leaves the apparent <video> content
            too small during the animation, especially at the beginning of the animation. Add a site-specific hack for
            YouTube sites which fires the "webkitfullscreenchange" event synchronously with the beginning of the enter
            fullscreen animation. This will cause YouTube to resize their <video> content during the period of time where we
            disable screen updates, and makes the enter fullscreen animation seamless.

            Add a static utility method, hostIsYouTube(), for the various pieces of this site-specific hack, and expand it

            YouTube.com will cause a "flash" of the full screen sized <video> element upon exiting full

            completes. Only YouTube sites and embeds, add a site-specific-quirk which runs the "fullscreenchange"
            event synchronously at the end of the exit animation. This causes YouTube's video resizing logic

            Drawing text in an SVG font causes load events to be fired.

            Don't flush pending load events in Document::implicitClose() for frameless documents.
            This is a targeted fix for an issue where parsing SVG fonts during layout would cause
            event dispatch to happen in the main document, leading to arbitrary JS execution.

            Note that the testcase only works in DRT/WTR, since once the SVG font is in cached
            by WebCore, we won't reparse it again. Caches are cleared between tests, so it will
            correctly fail if this should regress.

            Longer-term, we should clean this up and get rid of the global dispatch entirely.

            RootInlineBox::verticalPositionForBox() had some implicit conversions between
            LayoutUnit and int that caused overflow, and resulted in different comparison
            behavior with an int constant in different architectures, since overflow behavior
            is undefined.
            
            Specifically, VerticalPositionCache was written in terms of ints with a special
            0x80000000 "not found" value. However, 0x80000000 was being assigned to
            a LayoutUnit, which multiplies by 64 causing overflow. The result was then
            compared again with 0x80000000 which could pass or fail depending on overflow
            behavior.
            
            Fix by converting VerticalPositionCache to use LayoutUnits, and to have a bool
            return value with a result out param, instead of a special return value.
    
            Not easily testable, since the difference does not show in DRT output,

            REGRESSION (r167856): adobe.com no longer able to launch Create Cloud app using a URL with a custom scheme
            https://bugs.webkit.org/show_bug.cgi?id=136010
    
            Reviewed by Darin Adler.
    
            r167856 caused WebKit to stop scheduling certain kinds of navigations (window.location changes, meta-refresh,
            and some calls to window.open) when the request URL is invalid. Adobe.com performs one of these navigations to
            an invalid URL with an external scheme (aam:), relying on Safari's navigation policy delegate to ignore the
            navigation and launch the external app registered to handle aam: URLs. Since the navigation is no longer
            scheduled, the policy delegate is never executed and the external app never launches.
    
            Instead of not scheduling the navigation, allow it to proceed until the client's policy delegate has executed
            and made a decision. Only disallow the navigation if the policy delegate told WebKit to proceed with the load.
            This exposes these navigations to clients via the policy delegate and via willPerformClientRedirectToURL and
            didCancelClientRedirectForFrame on the frame load delegate.
            
            To constrain this check only to the navigation types covered by r167856, only two NavigationSchedulers
            (ScheduledRedirect and ScheduledLocationChange) enable the invalid URL check.
    
            Note that r167856 also caused an iOS regression, and this was resolved in r170120 by adding a linked-on-or-after
            check and a WebCore setting. Since the iOS regression is also resolved by the approach described above, this
            patch reverts r170120 (but keeps some of its tests).

            has already called 'scrollWheel' on the underlying platform widget. We need to return true in
            this case to avoid getting multiple copies of the scrollWheel event sent to the platform widget.

            [MSE] Implement a maximum buffer size for SourceBuffer

            Implement the MSE coded frame eviction algorithm: when new buffers are appended attempt
            to keep the amount of data buffered below a maximum size (which is determined by the media
            session manager) by freeing coded frames as follows:
                1 - Free frames in 30 second chunks from 0 to 30 seconds before the current time.
                2 - If there are time ranges after the range with the current time, free frames in
                    30 second chunks from duration back to the beginning of the time range after
                    current time.
    
            For now we DO NOT throw a QUOTA_EXCEEDED_ERR when we are not able to free up enough
            space to remain below the prescribed quota, because some big name, widely deployed, 
            code bases ignore the error and continue appending data as though the failed append
            succeeded, leading to a corrupted bitstream and failure to play.

            When the style change requires both layout and repaint, the style diff is set to
            'layout is needed' (and masks the repaint change) as normally layout is followed by a repaint.
            However, in compositing context, layout may not be followed by repaint, so when the style diff
            indicates layout, we need to figure out whether it implies repaint too.
            This logic should eventually be moved from RenderElement to RenderLayerModelObject/RenderLayer.

            Fixes an issue where gmail.com may fail to load the list of messages. In particular, a SQLTransactionCallback
            function may not be executed and hence Gmail will not display the list of messages and
            will subsequently display an error message.

            When a WebKit client defers loading of a page (e.g. -[WebView setDefersCallbacks:YES]), WebCore
            may still load the main resource, say if substitute data is available for it, and defer executing
            tasks, such as a SQLTransactionCallback function, by appending such tasks to the end of the list
            of pending tasks for the associated Document. This list of pending tasks is never processed when
            a client subsequently allows loading (e.g. -[WebView setDefersCallbacks:NO])). Therefore, we never
            execute a SQLTransactionCallback function that was deferred.

            Ideally WebCore would defer loading of substitute data when a WebKit client requests that loading
            be deferred and hence a SQLTransactionCallback function would be deferred as a consequence of the
            lack of JavaScript script execution (since substitute data wasn't loaded and hence any JavaScript
            script contained in the substitute data that initiates a SQL transaction isn't executed). For now,
            it's sufficient to only defer executing tasks when either there are existing pending tasks or the
            page defers loading and active DOM objects in the document are suspended (e.g. Document::suspendActiveDOMObjects() was called).

            If you have an existing range selected, and try to apply a select and replace operation, like capitalize,
            searching for that range will fail because it skips the currently selected range.

            For these cases, it seems the best way is to start the search from the start position, rather than relying on the

            In r170198 I added an "orphan scrolling nodes" code path that sets aside subtrees
            of scrolling nodes into an m_orphanedSubframeNodes map, which keeps them alive until
            they get reparented or destroyed. The nodes in that subtree remain in m_stateNodeMap,
            which holds raw pointers to them.
            
            However, ScrollingStateTree::commit() can clear m_orphanedSubframeNodes, which is
            sometimes non-empty at this point. When that happened, we would destroy nodes which
            were still referenced by m_stateNodeMap, with the result that a later query for the
            same nodeID would hand back a pointer to a deleted object.
            
            Fix by calling recursiveNodeWillBeRemoved() on nodes in the m_orphanedSubframeNodes
            before clearing it, which removes them and all their descendants from the state node map.

            [iOS] The raw bytes of an iWork document's PDF preview are displayed rather than the PDF itself

            Reviewed by David Kilzer.

            Some iWork documents contain pre-rendered PDF previews. When WebKit asks QuickLook to convert such a document,
            QuickLook will return this PDF as the converted response. However, until WebKit has sent the document's data to
            QuickLook, -[QLPreviewConverter previewResponse] will misleadingly tell WebKit that the converted resource will
            be of type 'text/html'. This leads WebKit to render the PDF preview as HTML.

            Instead of querying QLPreviewConverter for the previewResponse before we've sent it any data, postpone calling
            ResourceLoader::didReceiveResponse until we've begun to receive data via the QLPreviewConverter delegate. At
            that point -[QLPreviewConverter previewResponse] will have the correct MIME type and we can call didReceiveResponse.

            [MSE] Seeking occasionally causes many frames to be displayed in "fast forward" mode

            Reviewed by Eric Carlson.

            Three related fixes:

            In reenqueueMediaForTime(), update TrackBuffer.lastEnqueuedPresentationTime when we flush
            samples, so that the next time samples are re-enqueued, the starting point for re-enqueueing
            is correct.

            In sourceBufferPrivateDidReceiveSample(), do not add samples to the decode queue
            if they are before the current media time.

            When a seek is pending, but samples for the new time is not yet present in the SourceBuffer,
            the SourceBufferPrivate may signal that it's ready for new samples through the
            sourceBufferPrivateDidBecomeReadyForMoreSamples() method. In this situation, we should not
            continue to provideMediaData(), as that will append samples from the prior-to-seeking media
            timeline. Since the timeline may have moved forward due to the seek, a decoder may decide to
            display those frames as quickly as possible (the "fast forward" behavior) in order to catch
            up to the new current time.

            If a re-enqueue is pending, don't provide media data in response to being notified that the
            SourceBufferPrivate is ready for more samples. Wait until samples for the new current time
            are appended.

            Also, don't provide media data if we are waiting for a seek to complete.

            Reviewed by Benjamin Poulain.

            AppKit's contentInsets are factored into scroll positions and mouse positions, but
            in WebCore, we generally want all of those things to be factored out so that, for
            example, the scroll position of a document pinned to the top is the same whether
            or not there is a contentInset. So to fix hit-testing in WebKit 1 views with
            contentInsets, this patch factors the inset out or into of all coordinate
            conversion methods just like we do for the WebKit2 contentInset.

            This patch also adds the ability to test WK1 platformContentInsets with
            window.internals, and it re-names convertFromRenderer to 
            convertFromRendererToContainingView and also re-names convertToRenderer to
            convertFromContainingViewToRenderer.

            ScrollView::topContentInset() takes an optional parameter indicating whether the
            caller wants the WebCore::Page contentInset or the platform content inset. It’s
            necessary to distinguish between these cases because there is a lot of code that
            only wants the WebCore::Page contentInset since that feature is actually
            implemented in WebCore as opposed to being implemented at the platform level.

            We currently pass a SharedBuffer wrapped in WebCoreSharedBufferData to ImageIO for image
            decoding. This is not thread safe since ImageIO will access this buffer on a separate
            thread. We access SharedBuffer::buffer() on the other thread which resizes the Vector
            m_buffer if m_size is greater than the vector size. Since the code in SharedBuffer::append()
            sets m_size before appending the data to the buffer, m_size is out of sync with the m_buffer
            size for the entire duration of the Vector append which could be doing a lot of copying if
            the resource is large. While this change does not fix the race condition, we can at least
            reduce the chances of SharedBuffer::buffer() calling resize() by setting m_size after the
            cector has finished appending.

            styles, and this led to a crash in length conversion where the code
            assumes a parent style will be present.

            To keep this fix minimal, simply make the "parent style" a clone of the
            base element style.

            r171526 broke the case where we have a memory mapped file from the DiskImageCache in the
            SharedBuffer. In such a case, m_buffer is empty and createCFData() returned an
            WebCoreSharedBufferData with an empty buffer.

            Fix this by taking the easy route of bringing back the old code for the disk image cache
            file backed case. In the long run we probably want to remove the iOS specific disk image
            cache anyway.

            Review also uncovered another bug in r171526 where we were balancing an Objective-C alloc
            with a CFRelease which is incorrect when running under GC. Fix that by using adoptNS along
            with adoptCF which is what the code did before.

            No new tests because the bug only occurs on device and we can't run tests on device yet.

            this represents a change in behavior from WebKit1. If such usage of window.localStorage turns

            prepareForDestruction() can be called a number of times during teardown,
            but it's only necessary to actually execute it once.
            
            This was previously achieved by virtue of all callers of prepareForDestruction()
            first checking hasLivingRenderTree, and prepareForDestruction() tearing down
            the render tree, but that meant that prepareForDestruction() was not called
            for Documents who never had a render tree in the first place.
    
            The only part of prepareForDestruction() that is now predicated on hasLivingRenderTree()
            is the call to destroyRenderTree(); the rest of the function has the potential to be relevant
            for non-rendered placeholder documents and can safely deal with them in other ways.
    
            It is important to call prepareForDestruction() on non-rendered placeholder documents

            SharedBuffer::createCFData() calls data() as a way to coalesce the data array elements and
            segments into m_buffer. However, data() has an optimization where if we had a single element
            in the data array, it would just return that and not do coalescing. So when we passed
            m_buffer to WebCoreSharedData, we passed a buffer with no data in it.

            Fix this by bringing the optimization to createCFData() and return the CFDataRef from the
            data array if we just have a single element.

            No new tests. Should be covered by existing tests.

            The bug was caused by editorUIUpdateTimerFired calling respondToChangedSelection only if the selection was
            triggered by dictation instead of only if it was NOT triggered by dictation.

            Prior to r164401, AlternativeTextController::respondToMarkerAtEndOfWord exited early when SetSelectionOptions
            had DictationTriggered set. r164401 intended to move this check to editorUIUpdateTimerFired to avoid passing
            options around but the boolean condition was erroneously flipped.

            Fixed the bug by negating the condition in editorUIUpdateTimerFired.

            Sharing SharedBuffer between WebCore and ImageIO is racy and crash prone

            Reviewed by Simon Fraser.

            When passing image data to ImageIO for decoding, we pass an NSData subclass that is a wraper
            around SharedBuffer. This can be a problem when ImageIO tries to access the data on the CA
            thread. End result is data corruption on large image loads and potential crashes. The fix is
            to have SharedBuffer create a copy of its data if the data has been passed to ImageIO and
            might be accessed concurrently.

            Since Vector is not refcounted, we do this by having a new refcounted object in SharedBuffer
            that contains the buffer and we pass that in our NSData subclass WebCoreSharedBufferData.
            Code that would result in the Vector memory moving e.g. append(), resize(), now checks to
            see if the buffer was shared and if so, will create a new copy of the vector. This ensures
            that the main thread does not end up invalidating the vector memory that we have passed it
            to ImageIO.

            [MSE] YouTube video decode error when variant-switching

            Reviewed by Brent Fulgham.

            Test: media/media-source/media-source-overlapping-decodetime.html

            When variant-switching, the situation can arise where an existing sample with a presentation
            timestamp of N and a decode timestamp of M, and a new sample with a presentation timestamp > N
            and the same decode timestamp of M, will keep the new sample from being added to the SampleMap.
            This can result in a decode error when samples depending on that new, missing sample are enqueued.

            The MSE spec is silent on the issue of overlapping decode timestamps. However, it guarantees that
            presentation timestamps are non-overlapping. So instead of using just the decode timestamp as a key
            for storing the samples in decode order, use both the decode timestamp and the presentation timestamp.
            That ensures that samples with different presentation times but equal decode times are both inserted
            into the decode queue, and in the correct order.

            We currently pass a SharedBuffer wrapped in WebCoreSharedBufferData to ImageIO for image
            decoding. This is not thread safe since ImageIO will access this buffer on a separate
            thread. We access SharedBuffer::buffer() on the other thread which resizes the Vector
            m_buffer if m_size is greater than the vector size. Since the code in SharedBuffer::append()
            sets m_size before appending the data to the buffer, m_size is out of sync with the m_buffer
            size for the entire duration of the Vector append which could be doing a lot of copying if
            the resource is large. While this change does not fix the race condition, we can at least
            reduce the chances of SharedBuffer::buffer() calling resize() by setting m_size after the
            cector has finished appending.

            When the UI-side scrolling tree receives a requested scroll position update, it scrolls
            the node (e.g. a frame) then traverses child nodes to update them, e.g. for fixed position.
            However, we would always use a viewport rect for the main document (from the scrolling tree),
            which is not appropriate for subframes. Subframes should just use their own visible

        instead.

        Until then, removing the outdated syntax will ensure that no one
        ends up relying on it in WebKit's implementation.

        Reviewed by Benjamin Poulain.

        When individual elements inside an overflow:scroll with -webkit-overflow-scrolling: touch
        had touch event listeners, we would fail to take the scroll offset into account when
        building the touch event region, causing touches on those elements to fail after scrolling.
        
        Touch event region building uses RenderObject::absoluteClippedOverflowRect(), and that
        code path tries to fix up repaint rects to work correctly in composited overflow:scroll.
        However, that broke the touch region computation.
        
        Fix by only ignoring the scroll offset for calls to computeRectForRepaint() which
        have a non-null repaintContainer (which indicates that we're doing a repaint in the
        compositing layer), and for which the repaintContainer is the containing block
        which is using composited scrolling. This restores correct behavior to the event region
        code which always calls this with a null repaintContainer.

        [CSS Grid Layout] Support sparse in auto-placement algorithm
        https://bugs.webkit.org/show_bug.cgi?id=134544

        Reviewed by Sergio Villar Senin.

        This patch implements sparse mode for auto-placement algorithm, which is
        the default mode in the new grid-auto-flow syntax. It keeps track of the
        auto-placement cursor in
        RenderGrid::placeAutoMajorAxisItemsOnGrid() and updates it accordingly
        when auto-positioned items are placed.
        If we're in dense mode it resets the cursor after each item (which keeps
        the old behavior that was using dense mode by default).

        GridIterator has been adapted to look for empty areas from a given
        position in both directions.

        Bug 134836 - [New Multicolumn] Crawl to check for compositing between us and the enclosingPaginationLayer
        https://bugs.webkit.org/show_bug.cgi?id=134836

        Reviewed by Dean Jackson.

        The paginatedAndComposited bit being set in updateLayerPositions just didn't work, since compositing states
        can change without triggering that function. This patch just gets rid of the bit and does a crawl every time
        to check. This ensures that changes in compositing states don't necessitate any changes in pagination,
        since the lookup will always check the current compositing state.
        
        The new function that does this check is hasCompositedLayerInEnclosingPaginationChain.
        
        I have been unable to reproduce this issue, and this is therefore a purely speculative fix. I have no test

        Elements with rendering disabled due to dimensions should not contribute to parent bounding box
        https://bugs.webkit.org/show_bug.cgi?id=134184

        Reviewed by Dirk Schulze.

        SVG elements that have rendering disabled should not contribute to any ancestor elements bounding box.
        Examples of elements with rendering disabled:
        - basic shape with width <= 0 or height <= 0
        - path with no path data (d attribute missing or empty)
        - polyline or polygon element with no point data (points attribute missing or empty)

        To achieve this a method (isRenderingDisabled) was added to RenderSVGShape and it's derived classes.
        This is used to determine if an element is included when creating the union of child bounding boxes
        in a container element.

        It would be possible to change the function instead to evaluate common attributes based

        The primary change necessary to fix the mediasource-duration.html test was to add support
        for delaying the completion of a seek operation until the HTMLMediaElement's readyState
        rises to > HAVE_CURRENT_DATA. This is accomplished by modifying MediaSourcePrivate to have
        waitForSeekCompleted() and seekCompleted() virtual methods. These are called by MediaSource
        when a seek operation results in the current time moving outside the currently buffered time
        ranges, and when an append operation results in the readyState changing, respectively.

        A number of other drive-by fixes were necessary to get this test fully passing, as noted
        below.

        Make the MediaSource the primary owner of the media's duration, rather than the MediaSourcePrivate.
        Move the MediaSourcePrivateClient pointer to the MediaSourcePrivate from the MediaPlayerPrivate, so

        Partition the CSS rules based on the most specific filter of the rightmost fragment

        Reviewed by Andreas Kling.

        Previously, RuleSet was partitioning each rule based on the rightmost filter.
        While fast, this had the side effect of putting many selectors with ID match in the class
        bucket (because the selectors are generally written starting with the ID).

        This patch replace the code of findBestRuleSetAndAdd() by a simple loop going over all

        We first loop over all the CSSSelectors related by SubSelector, this correspond to the rightmost fragment.
        If a filter with high specificity is found, we add the rule immediately and end there.
        If a filter that is not very specific is found, we keep a pointer to the selector to use it later.

        [CSS Grid Layout] Update grid-auto-flow to the new syntax
        https://bugs.webkit.org/show_bug.cgi?id=134057

        Reviewed by Sergio Villar Senin.

        In last versions of the spec grid-auto-flow syntax has changed. New
        syntax is:
        [ row | column ] && dense? | stack && [ row | column ]?

        Implemented parsing for new syntax and added/modified test cases in
        current layout tests.

        For the moment, the implementation keeps working in the same way, but
        using "stack" value for grid-auto-flow property instead of "none". This
        should be fixed in a follow-up patch once "stack" is properly
        implemented.

        Also "dense" needs to be reviewed. Right now auto-placement algorithm is
        always "dense" and never "sparse".

        No new tests, update current tests to add new cases.

        [MSE] Overlapping appended ranges must cause the decoder to flush and re-enqueue.
        https://bugs.webkit.org/show_bug.cgi?id=134805

        Reviewed by Eric Carlson.

        When appending a range of media data which overlaps with an existing range, SourceBuffer
        must cause the decoder to flush and re-enqueue samples. Those samples removed by appending
        the overlapping range may have already been enqueued for display, and unless the decode
        queue is flushed, corruption or decode errors may occur as the new samples are enqueued for
        display.

        Add a boolean flag onto TrackBuffer to indicate whether the decoder needs to be flushed and
        re-enqueued the next time an append operation completes. Set this flag whenever samples are
        removed due to overlapping or an explicit call to removeCodedFrames(). Move the contents of
        sourceBufferPrivateSeekToTime() (which previously did flushing and re-enqueueing) into a new
        function, reenqueueMediaForTime(), which can be called from sourceBufferPrivateAppendComplete().

        Drive-by fix: findSyncSampleAfterDecodeIterator() would return the passed in iterator if that
        sample is a sync-sample. Fix this to correctly return the next sync sample.

        Drive-by fix: Use a SampleMap, rather than a DecodeOrderSampleMap, to track erased samples
        so that the erasedSamples are correctly accounted for in both presentation and decode orders.

        Non-critical relief is for clearing out things that are really not

        On iOS, only flip the "WebKit is under memory pressure" flag when we
        are under *critical* memroy pressure, rather than doing it early on
        and gimping ourselves because other processes are too big.

        Reviewed by Alex Christensen.

        When a cache entry has expired, it is invalidated when a request for the corresponding url is started.
        This is too early, since the resource is possibly not modified (even though it has expired),
        and the server might respond with a 304 (not modified) response.
        When we then receive a 304 response, the cache entry is deleted, and we have no cached response/data to provide.
        This can be solved by not invalidating the entry when a request for that url is started,
        but instead invalidate when a 200 OK response is received (which means the resource has been modified).

        CSS canvas color parsing accepts invalid color identifiers
        https://bugs.webkit.org/show_bug.cgi?id=134661

        Reviewed by Benjamin Poulain.

        Current implementation of the CSSParser::parseSystemColor assumes
        that if a valid cssValueKeywordID is got then it has to be a valid
        color. Such assumption is wrong and lead to many bugs and layout
        test failures.

        The parseSystemFunction determines now whether the parsed color is
        valid or not.

        Addtionally, a new method has been added to share the logic of
        determining whether a CSSValueID is a valid primitive values for
        colors or not. Generally, we should avoid passing invalid color
        identifiers to the theming API.

        No new tests, but added additional cases to the

        [iOS] caption size is sometimes incorrect in fullscreen
        https://bugs.webkit.org/show_bug.cgi?id=134740

        Reviewed by Jer Noble.

        Captions on iOS are displayed in fullscreen with a TextTrackRepresentation object. Because
        the fullscreen video presentation is controlled by code in the UI process running on the
        UI thread, WebCore is notified of changes to fullscreen state asynchronously. This resulted
        in the TextTrackRepresentation object being created and/or destroyed too late some of the 
        time, which caused us to sometimes display captions incorrectly. Fix this by setting up and
        tearing down the TextTrackRepresentation object when WebCore's 'webkitfullscreenchange'

        Ensure we compute the height of replaced elements to 'auto' when appropriate.

        Reviewed by David Hyatt.

        This fixes two issues:

        1) If a replaced element has a percentage height specified then its
        height should compute to 'auto' when its containing block does not
        have a height 'specified explicitly'. We were taking this to mean when
        its containing block's specified height value is 'auto' - in fact it
        means when the containing block's computed height is auto.

        2) Top and bottom on the containing block should only affect the
        height of the block if that block has absolute or fixed position.

        This brings us into line with IE, Firefox, and Chrome.

        This patch removes 2 integral roundings from InlineFlowBox:
        1. Border and padding sizes are implicitly integral truncated by the 'int' return type
           of borderLogicalLeft/Right()/paddingLogicalLeft/Right(). It results in losing
           fractional border/padding values.
        2. Painting rectangle is explicitly rounded which pushes border and

        Being a SVG font is a property of the FontData object, not

        In r170572 I attempted to prevent the page zoom from happening
        when the user was attempting to fullscreen the video. That fix was
        not complete, because it relied on the touchstart event being
        sent before a gesture event. It turns out this doesn't always happen,
        so we need to apply the same check in the gesture event - if the
        gesture began with two fingers on the media, don't do a page zoom.
        The exception is zooming out, if you've managed to make the video
        cover the entire screen (also, the pinch-out-of-fullscreen gesture
        does not get handled by WebKit).

        input type=range element should only fire change events after committing a  value
        https://bugs.webkit.org/show_bug.cgi?id=134545

        Reviewed by Dean Jackson.

        A "change" event was fired every time the slider thumb element was dragged
        by the user. The "change" event is now fired only after the thumb
        element has stopped moving; previously, both "input" and "change" events
        where dispatched while changes were being made. This new behavior is
        consistent with the specification (cf.
        http://www.whatwg.org/specs/web-apps/current-work/multipage/common-input-element-attributes.html#event-input-change),

        [Mac] WebKit1 WebView iframe not responding to scroll gestures
        https://bugs.webkit.org/show_bug.cgi?id=134569
        <rdar://problem/17309008>

        Reviewed by Simon Fraser.

        New test: platform/mac/fast/scrolling/scroll-iframe-fragment.html

        WK1 scrollable areas are implemented on top of PlatformWidget (i.e., NSView) objects. They only
        perform a scroll operation if the EventHandler::handleWheelEvent method returns 'false', indicating
        that the Cocoa layer should do scrolling work. This is in contrast to WK2, where the scrolling is
        handled separately and we return 'true' from EventHandler::handleWheelEvent to indicate that the
        scroll event has been handled and that no other work is needed. This mismatch in the meaning of
        EventHandler::handleWheelEvent means that WK1 views do not properly handle scroll wheel events.

        To correct this, we need to see if we are acting on an Element backed by a PlatformWidget. When we
        are (the WK1 case) we want to return 'false' to instruct the Cocoa object to do the scroll operation.
        To implement proper latching behavior in WK1, we must return 'true' in the case where we are latched
        to a PlatformWidget, and that PlatformWidget did not start the scroll gesture at the edge of
        the region in the dominant scroll direction.

        Finally, additional logic was needed to determine whether the PlatformWidget is scrolled to the
        edge in the dominant scroll direction.

        Since WebCore::IconDatabase is not RefCounted there’s no obvious way to keep it alive until it is

        This isn’t generally a problem because they are usually a singleton that lasts the lifetime of the process.

        In the WebKit2 case, WebCore::IconDatabases can come and go as their owning WebIconDatabases come and go.

        This issue is caused by the order of teardown for RenderLayers.

        access the RenderLayer's backing that has already been cleared. This

        renderer from the tree. r160908 avoided dealing with this by simply always reconstructing the subtree.
        Unfortunately plugin lifetime is currently tied to its renderer so this would cause the plugin to restart.

        UIKit has some special code to avoid tap highlight on certain type of object. This is not very flexible
        since the page has no way of overriding that behavior.

        This patch implement the same feature by changing the default stylesheet. The tap highlight is disabled
        by default for those object, and enabled for images that are in a link.

        Avoid copying function object in lambda function in ScrollingThread::dispatchBarrier(); actually use move semantics
        https://bugs.webkit.org/show_bug.cgi?id=134470

        Reviewed by Anders Carlsson.

        Currently we always copy construct the captured std::function object when calling callOnMainThread()
        in the lambda function created in ScrollingThread::dispatchBarrier() because captured variables are
        const in a lambda expression's body by default. That is, the std::function object is captured as const.
        Instead, we should mark this lambda expression as mutable so the captured std::function object is
        non-const and hence we can use move semantics when passing it to callOnMainThread().

        Tiles on bottom of screen are not always allocated when necessary

        Reviewed by Simon Fraser.

        The initial visibleRect is in the coordinate of the root layer, so its origin
        is at the top left of the view. The initial rect we were using doesn't
        include the contents inset, so it was too short, which was causing tiles near
        the bottom of the screen to not always be allocated if the tile threshold was
        close to the bottom of the view. Instead, we want to include the contents
        inset size so the visible rect includes the entire view.
        GraphicsLayerCA::recursiveCommitChanges() takes care of mapping and cropping
        the visible rect into the tiled layer's coordinate system, at which point it
        is used for visible tile logic.

        No need to lazily initialize ResourceResponse internals when accessing timing data.
        <https://webkit.org/b/134437>
        <rdar://problem/17499876>

        When building with ENABLE(WEB_TIMING), the last thing that would happen when
        serializing a ResourceResponse in the network process is that we'd retrieve
        the ResourceLoadTiming to encode it as part of the response. Doing so would
        trigger the lazy instantiation of ResourceResponse's internal data structures.

        Since timing data is not actually lazily instantiated, we can just not do that.

        This shaves off ~550ms of network process main thread time on PLT, reducing
        response latency by not doing unnecessary stuff before letting the web process
        look at the downloaded data.

        Reviewed by Carlos Garcia Campos.

        The current GObject DOM bindings generator is duplicating code when

        Remove BufferForAppendingHyphen
        https://bugs.webkit.org/show_bug.cgi?id=134376

        Reviewed by Darin Adler.

        It is legacy, from a time when that code was using a Vector.

        The problem is that StringBuilder's memory was also implicitly used to keep
        the string alive for the lifespan of the TextRun. That seems quite dangerous
        as changes in StringBuilder could have changed that.

        To fix the lifetime issue, my first idea was to make it explicit by passing
        a String reference to hold the memory alive, and a boolean to say if the text
        need an hyphen. The problem with that is this code is very hot and I made things
        worse.

        The solution with this patch is to just pass a pointer to a String to do both
        the buffer reference, and the decision to add the hyphen. Having a single
        argument with 2 meanings is not pretty but that's not worse than the old buffer.

        <rdar://problem/16762224>

        Make -webkit-overflow-scrolling:touch scrolling work correctly when one axis
        has overflow:scroll and the other overflow:hidden. Also fix scrolling in RTL
        contexts.
        
        An RTL scroller with overflow-x:hidden will have a non-zero scroll origin,
        and needs to truncate the scrolled content on the left side. To pass the
        correct geometry to the UI process, we need to introduce the concept of
        "reachable" size as well as total content size; normally these are the same,
        but will differ when scrolling is only allowed on one axis but there is overflow
        on both axes.
        
        To get the reachable size, add RenderLayer::scrollableContentsSize().
        
        RenderLayer::visibleSize() was wrong; the function should return the size of the 
        scrollable portion, but used layer size which includes borders. Fix to use pixelSnappedClientWidth()/Height(),
        which is what we use for scrollbar computations.

        While running webkit on a Debian virtual machine I stumbled upon an issue where JS
        setTimeout callbacks were not being properly invoked due to machine limitations and the

        We skip those because the getter conflicts with the get_type()
        function of all GObjects. We should use a different name for them. As
        a general rule we use the last word of the class name, something like:

          webkit_dom_blob_get_type() -> webkit_dom_blob_get_blob_type()
          webkit_dom_event_get_type() -> webkit_dom_event_get_event_type()

        It's consistent with other existing DOM methods like
        webkit_dom_xpath_result_get_result_type() or webkit_dom_css_value_get_css_value_type().
        This patch also adds some exceptions for particular cases.

        This was added as belt-and-suspenders while the supporting mechanism was being
        developed in CFNetwork, and there's no evidence of a race today. This change
        turns the runtime checks into debug-only assertions.

        Saves ~300ms of main thread time on PLT.

        [CSS Grid Layout] Properly support for z-index on grid items
        https://bugs.webkit.org/show_bug.cgi?id=103329

        Reviewed by Benjamin Poulain.

        From Blink r157620 by <jchaffraix@chromium.org> and r172402 by
        <wangxianzhu@chromium.org>.

        The specification says that grid should match flexbox and force
        grid items to be stacking context if z-index is set, regardless
        of 'position'. After this change, this is what happens.

        Previously z-index changes of static positioned objects were ignored.
        However, z-index is applicable for some static positioned objects,
        such as grid items. Ignoring them makes the object not to be properly
        painted on z-index change.

        As StyleResolver has ensured that z-index is non-auto only if
        applicable, RenderStyle::changeRequiresLayerRepaint() should not check
        again (with inconsistent conditions).

        Reviewed by Zalan Bujtas.

        If a given remote layer tree commit contains changes of layers for viewport-constrained
        objects, then the associated scrolling tree also needs to show that the layers changed,
        since we need to re-run the "viewport changed" logic in the UI process to get the
        layers correctly positioned for the current zoom level.
        
        The bug was that page scale changes resulted in small "pixel alignment" position
        changes which touched layers, but we didn't commit any scrolling tree changes. So
        the scrolling tree commit would result in visibly stale layer positions, with no scrolling tree
        update to adjust them for the current transient zoom.

        Fix by making use of the existing "alignment offset" field in the ViewportConstraints
        data, and having RemoteScrollingCoordinatorProxy::connectStateNodeLayers() note that
        fixed or sticky layers changed if any properties of fixed or sticky scrolling tree

        Crash in ScrollingTree::isRubberBandInProgress()

        -and corresponding-
        <rdar://problem/16247911>

        Reviewed by Geoffrey Garen.

        This crash appears to have been caused by http://trac.webkit.org/changeset/161276 
        which moved the ScrollingNode creation code from ScrollingTree over to 
        ScrollingCoordinator. This creates a thread safety issue. In the crashing case, we 
        believe that the ScrollingCoordinator's ScrollingTree pointer had been null-ed out
        even though the ScrollingTree was kept alive by the bind call to propagate 
        commitNewTreeState() over to the scrolling thread. The fix is to move node 
        creation back to the ScrollingTree and to use the this pointer to create new
        nodes rather than the ScrollingCoordinator's ScrollingTree pointer.

        Don't allow ScrollingCoordinator to handle ScrollingTreeNode creation.

        Add all blend modes to feBlend

        feBlend should support all blend modes from CSS and Canvas
        https://bugs.webkit.org/show_bug.cgi?id=134296

        Reviewed by Dean Jackson.

        Add all blend modes to <feBlend> (the SVG filter primitive) that are also
        supported by HTML Canvas and CSS.

        In addition, add "normal" blend mode to HTML Canvas as requested by the
        CSS Compositing and Blending specification. (Referenced from HTML Canvas.)
        With this change, SVG, CSS and Canvas truly share the same blend modes and
        even the same keywords. This is much easier to for web authors.

        Reviewed by Enrica Casucci.

        Unchecked access of details pointer in the Document marker led to the crash.
        It seems erroneous to allow creation of a DocumentMarker without details when one is expected, because it
        carries the dictation context (not just the description).
        Also, add in ASSERTs to catch scenarios where a nullptr might be passed in.

        Tiles on bottom of screen are not always allocated when necessary
        https://bugs.webkit.org/show_bug.cgi?id=134272

        Reviewed by Simon Fraser.

        The initial visibleRect is in the coordinate of the root layer, so its origin
        is at the top left of the view. The initial rect we were using doesn't
        include the contents inset, so it was too short, which was causing tiles near
        the bottom of the screen to not always be allocated if the tile threshold was
        close to the bottom of the view. Instead, we want to include the contents
        inset size so the visible rect includes the entire view.
        GraphicsLayerCA::recursiveCommitChanges() takes care of mapping and cropping
        the visible rect into the tiled layer's coordinate system, at which point it
        is used for visible tile logic.

        InlineTextBox's m_len can be an unsigned (rather than an unsigned short)
        https://bugs.webkit.org/show_bug.cgi?id=134173

        Reviewed by Daniel Bates.

        After Zalan's talks with Kling, it seems that the simple line layout code
        might alleviate the need for the space savings in InlineTextBox. Given this,
        it would be beneficial to be a little more safe by using unsigneds throughout.

        For example, we have code like "void setLen(unsigned len) { m_len = len; }"
        which might silently break if given particular inputs.

        No new tests because there is no behavior change.

        CSS JIT: Add positionInRootFragments to SelectorFragment
        https://bugs.webkit.org/show_bug.cgi?id=133609

        Reviewed by Benjamin Poulain.

        Some non-backtrack-related predicates use relationToRightFragment information
        to decide whether checkingContext->elementStyle should be refered.
        To make it works correctly, add the positionInRootFragments field to SelectorFragment.
        When positionInRootFragments == Rightmost and relationToRightFragment == Rightmost,
        we should see checkingContext->elementStyle.

        need to be re-performed in seekTimerFired(), in case the m_player has been cleared between when the seek was initiated
        and when the asynchronous section is performed.

        HTMLMediaElement seek algorithm should allow cancelling previous seeks.

        Reviewed by Eric Carlson.

        Test: media/video-seek-double.html

        Fulfill the requirement of the §4.7.14.9 seeking algorithm to do steps 5+ asynchronously and cancel
        previous instances of the algorithm.

        For the html/ parts of the algorithm, implement this by adding a seek timer, which when fired will
        issue steps 5-12. MediaPlayerPrivateAVFoundation will already coalesce multiple seek operations, so nothing
        additional needs be done there.  However, MediaPlayerPrivateMediaSourceAVFObjC needs to implement the same
        pending seek logic in case additional seeks were issued after the html/ algorithm reached step 12.

        In r169053 I moved some updateDrawsContent() into updateAfterDescendents(),
        but this isn't called when a composited layer gains or loses a mask (which
        doesn't cause a layout). This caused us to fail to allocate backing store
        when gaining a mask, resulting in missing content.
        
        Fix by calling updateAfterDescendents() from RenderLayer::styleChange()
        when the layer config isn't changing.
        
        Also remove a condition in isSimpleContainerCompositingLayer() that caused us
        to fall off the simple layer path for masked layers, since this works just
        fine.

        When an object flowed in multicol is moved from in-flow positioning to out-of-flow positioning,
        its information must be removed from the flowthread prior to the change being made. 
        Otherwise, the flow thread will no longer be its containing block and a reference to it

        With the newer animated controls in OS X Yosemite, we need
        to tweak the fudge-factor margins for positioning. In a recent
        patch I added another fudge, which I'm removing with this. I'm
        not sure where the older values came from, but I've checked with
        the latest AppKit sources and am using the sizes they implement
        for the controls.

        This will rebaseline a lot of tests, since I've made small tweaks

        In addition, retrieve the <video> element bounds and create an AVPlayerLayer with a matching size, so that

        [GTK][EFL] Use OpenType MATH fonts by default.

        Reviewed by Chris Fleizach.

        In order to support stretching of horizontal operators and large
        operators in display mode as well as to improve the drawing of radicals,
        we need to use an OpenType MATH table. This commit makes the MathML code
        try "Latin Modern Math" first, which is an OpenType version of Knuth's
        popular Computer Modern font and is packaged with most TeX
        distributions (e.g. TeX Live on Linux). This should work well on the
        EFL & GTK ports for which the initial OpenType MATH support has been
        tested. Other ports will be handled later.

        With the newer animated controls in OS X Yosemite, we need
        to tweak the fudge-factor margins for positioning. In a recent

        not sure where the older values came from, but I've checked with
        the latest AppKit sources and am using the sizes they implement
        for the controls.

        This will rebaseline a lot of tests, since I've made small tweaks

        Reviewed by Simon Fraser.

        Most of the RenderLayer::convertToLayerCoords() callers are only interested in
        the offset from the ancestor layer by passing LayoutPoint(0, 0) as the coordinate to convert.
        Introducing offsetFromAncestorLayer() makes those calls more explicit/self-explanatory.
        It helps simplifying the callsite's code.

        When nodes were detached from the scrolling tree, we would previously throw away
        all descendant nodes, expecting that they would be re-attached as we walk the compositing
        layer tree in RenderLayerCompositor.
        
        However, this doesn't work across frame boundaries; the subframe may never update
        its compositing layers again, so would lose all its scrolling nodes.
        
        Fix by having ScrollingStateTree::detachNode() by default set aside subframe nodes
        into a hash map. On reattach, we'll look in the hash map and pull out an existing node
        (with its children intact) if possible.

        Move generate prototype and constructor classes into the generated implementation files
        https://bugs.webkit.org/show_bug.cgi?id=134054

        Reviewed by Oliver Hunt.

        In an effort to reduce the size of the generated bindings headers, which is important
        as the generated headers get included in a lot of places, this patch moves the prototype
        and constructor declarations from the header to implementation file. This works because,
        for the most part, no code cares about the prototype or constructors except the instance.

        There are a few exceptions which had to be accounted for:
        - The global objects (JSDOMWindow and JSWorkerGlobalScope) need to have their prototypes
          available during initialization, so they remain in the header.
        - JSLocation requires customizing some aspects of the prototype behavior, so its prototype,
          and any future class that uses JSCustomNamedGetterOnPrototype or JSCustomDefineOwnPropertyOnPrototype,
          remains in the header.
        - A few classes had custom constructor functions. Instead of keeping the entire constructor
          in the header, I opted for pulling just the static constructor function into the header, and
          modifying the custom constructors to use the DOMConstructorObject type as the callee, since the
          more specific type was unnecessary.

        As a result of making these changes, I was also able to remove the #include of JSDOMBinding.h from
        all the headers, which brought in quite a bit.

        ScriptExecutionContext::Task, FileThread::Task parameters should be values

        Reviewed by Anders Carlsson.

        r170106 and similar previous changesets enforced ScriptExecutionContext::Task and
        FileThread::Task parameters as rvalue references. There's technically nothing wrong
        with that, but since both classes are move-only it is also not strictly required.
        Accepting these parameters as values is more common in C++ value semantics as well.

        Subtrees with :first-child and :last-child are not invalidated when siblings are added/removed
        https://bugs.webkit.org/show_bug.cgi?id=133934

        Reviewed by Antti Koivisto.

        When adding/removing nodes on an element, we try to invalidate only the elements that are
        affected. In the case of :first-child and :last-child, that optimizations is implemented
        through two types of flags that are updated during style resolution.

        The first flag is childrenAffectedByFirstChildRules (childrenAffectedByLastChildRules),
        set on the parent of any element that could be affected by :first-child (:last-child).

        The other part of the optimization is marking the style itself with firstChildState (lastChildState)
        to further reduce invalidations.

        The problem in this case happen with a subtree of element is detached. Since there is no renderer,
        the computed style is resolved ad-hoc and stored directly on the element. When the element is moved,
        the computed style was never cleared because the invalidation optimizations were not handling
        elements without style.

        Credit to Yusuke Suzuki for discovering the issue and creating test cases.

        Reviewed by David Kilzer.

        Following <http://trac.webkit.org/changeset/167856> we disallow "navigation to any URL that is
        invalid, except for JavaScript URLs, which need not be valid." A byproduct of this policy
        decision is that we no longer notify the WebKit client to about a navigation if the destination
        URL is invalid. And some apps, including the HSBC app for iOS, have logic to intercept URLs
        as a means to pass data from their WebView-embedded web app to the WebView. We should expose a
        setting called allowNavigationToInvalidURL (disabled by default on all ports and conditionally
        enabled on iOS) to toggle whether WebCore allows navigation to any URL, even if its invalid,
        so as to not break clients that intercept URLs and have custom logic to handle them.

        This isn't really necessary since ScriptExecutionContext::Task is non-copyable

        [iOS] Input type=time elements styled with SVG fonts have 0 width

        Reviewed by Simon Fraser.

        Refactor how the LocalizedDateCache returns maximum widths for input elements. Currently,
        measuring the width of an SVG font requires a RenderObject for context, which the
        LocalizedDateCache can't know about (it would be a platform violation). Instead, the
        LocalizedDateCache can return the strings that it would use to measure the width, and the

        [UI-side compositing] fix reflections on composited layers
        https://bugs.webkit.org/show_bug.cgi?id=133942

        Reviewed by Tim Horton.

        Fix reflections on composited layers. There are two main set of changes.
        
        First, a PlatformCALayerRemote which is a clone has to track the layer
        it is a clone of, so it knows where to grab the contents from in the UI process.
        This layer may be told that its contents need updating out of order during
        recursiveBuildTransaction(), so we need some small changes in RemoteLayerTreeContext
        to allow a layer to add itself to the set of layers requiring commit.
        
        In the UI process, a new step is added to RemoteLayerTreeHost::updateLayerTree()
        to go through clones, and copy their contents from the origin layer.
        
        The second set of changes makes platformCALayerLayerDidDisplay() work for
        UI-side compositing by not taking a PlatformLayer*, but instead a PlatformCALayer*.
        PlatformCALayer::setContentsChanged() changed to copyContentsFromLayer() so we know
        what the origin layer is.

        Use the string data that comes from the generated HTTPHeaderNames.cpp file
        for sharing header name data instead. In the future we can do something more fancy where
        we'll hash the HTTPHeaderName enum directly, but this is good enough for now.

        Sometimes asking accessibilityIsIgnored() will cause a newObject to be detached immediately after its created. 
        The creation function holds a reference with RefPtr as long as it lives, but when that method returns, the object goes away.

        With that out of the way, I saw the same backtrace lead to updateLayoutIgnorePendingStylesheets being called while still inLayout.

        [Bindings] "nullable" sequence support is incomplete (i.e. sequence<NativeType>?)
        https://bugs.webkit.org/show_bug.cgi?id=131240

        Reviewed by Darin Adler.

        Nullable sequences are not fully supported in WebKit's
        code generator machinery. Although the generated code
        does add "is nullable" check to the evaluation condition
        (i.e. if (arg.isNull() || ...)), when the JSValue
        that holds a "null" JSObject is actually to be "converted"
        to a native Vector<T>, it fails.

        The reason for the failure is in JSDOMBindings::toNativeArray.
        This method verifies that JSValue does not hold a "non-null"
        object, and it bails out.
        Analogly, the "ref ptr" variant of this method (toRefPtrNativeArray)
        does support nullables.

        Patch fixes it be checking for a "null" JSValue check before hand.

        Store DOM constants directly in the JS object rather than jumping through a custom accessor
        https://bugs.webkit.org/show_bug.cgi?id=133898

        Reviewed by Oliver Hunt.

        Instead of implementing constants as custom accessors that just happen to return a value,
        we now store the constant directly in the HashTableValue array (where the GetValueFunc used
        to be). 
        
        - For the case where the constant is accessed via the static table (still in use for instances 
          and some prototypes), the static lookup function will set the value on the property slot,
          instead of passing a function pointer.
        - For the case where the constant is eagerly reified (most prototypes and all constructors) the
          constant is put directly in the object.

        In micro benchmarks this looks to be around a 4x speedup on the use of DOM constants.

        This also removes support for constant strings in IDL, which we had no uses of.

        Masks disappear when layers become tiled
        https://bugs.webkit.org/show_bug.cgi?id=133892
        <rdar://problem/17309793>

        Reviewed by Tim Horton.
        
        There were several problems with tiled mask layers.
        
        First, when a layer became tiled it failed to re-apply the platform layer
        for its mask; fixed by adding MaskLayerChanged to the set of flags in
        swapFromOrToTiledLayer().
        
        Secondly, in CA, a mask layer's superlayer is the layer which is it masking,
        so the if (oldLayer->superlayer())... code in swapFromOrToTiledLayer() would
        erroneously try to swap out a sublayer on the superlayer with the mask.
        
        Thirdly, the mask layer is updated after its host layer, but when the mask layer
        become tiled, there was no code that updated the mask platform layer on its
        host layer. Fix by:
            1. setting a bit on a layer to note that it's being used as a mask.
            2. setting the parent of such a layer to its host layer (mimicking CA)
            3. when the mask becomes tiled, dirtying the MaskLayerChanged bit on
               its parent and adding a clause to commitLayerChangesAfterSublayers()
               to update the mask layer.
        
        Finally, ASSERTION FAILED: owningGraphicsLayer()->isCommittingChanges() would
        fire because we failed to set the m_isCommittingChanges flag while committing
        the mask layer. Fix by moving the TemporaryChange<bool> that sets this flag
        into commitLayerChangesBeforeSublayers() and commitLayerChangesAfterSublayers().
        
        Also used safe casts in more places in GraphicsLayerCA.

        Draw radicals with glyphs for better rendering

        Reviewed by Chris Fleizach.

        We rewrite RenderMathMLRoot in order to fix bugs with SVG transforms and dynamic modification of children and allow drawing with an OpenType MATH table.
        The drawing of the radical sign (without the top bar) is now moved to a RenderMathMLRadicalOperator class inheriting from RenderMathMLOperator.
        This class fallbacks to the original drawing with graphic primitives if an OpenType MATH table is not available.

        [CSS Grid Layout] Introduce an explicit type for resolved grid positions
        https://bugs.webkit.org/show_bug.cgi?id=131732

        Reviewed by Sergio Villar Senin.

        We were using simple size_t integers to represent resolved grid
        positions in our internal data structures. This change allows us to
        clarify the code, avoid potential off by one mistakes, and move the
        resolving code to a central place.

        A new class GridResolvedPosition has been created and the related
        methods have been moved there from RenderGrid.
        GridSpan is now defined by two GridResolvedPosition, so all the code
        using it has been modified to adapt it to GridResolvedPosition.

        No new tests as it is already covered by current tests
        (fast/css-grid-layout/).

        [GTK] Unsupported browser in www.icloud.com

        Reviewed by Martin Robinson.

        We claim to be Safari (among others) to ensure maximum
        compatibility with existing web sites. Valid Safari UA strings do
        always (since Safari 3.0) contain the string "Version/X" before
        the "Safari/X" part. We were wrongly only adding it in very
        specific cases and we were placing it at the wrong position as it
        must precede the "Safari/X" part.

        From now on we unconditionally prepend the "Version/X" string to
        the "Safari/X" part as we always claim to be Safari. This makes
        the NeedsSafariVersion6 quirk invalid. This not only fixes
        "unsupported browser" issues in icloud.com, but also in
        globalforestwatch.com and live.com among many others.

        Apart from that I'm bumping the Safari Version in the UA to 8.0 as
        we're already claiming to be "Safari/538.35"" which corresponds to
        Safari 8 beta.

        Reviewed by Brent Fulgham.

        When a request is taken from the cache, its cached response headers are empty, if the cache entry was created in the same session.
        It is only when the cache entry is loaded from disc, that the response headers are properly set.
        We need to set the cached response headers in both cases.
        There is also an issue if two jobs are loading the same url at the same time.
        Both jobs will then write to the cache content file, and create invalid content.
        This can be fixed by only letting the first request write to the content file.

        [GTK] Use a different user agent string depending on the site
        https://bugs.webkit.org/show_bug.cgi?id=132681

        Reviewed by Anders Carlsson.

        We have changed the user agent string several times to try to fix
        broken websites that require specific things in the UA string to
        properly work. But everytime we change the UA string to fix a
        website we break others. We could use different UA string
        depending on the website. UserAgentGtk code has also been cleaned
        up, using NeverDestroyed instead of DEPRECATED_DEFINE_STATIC_LOCAL
        and avoiding unneeded conversions to UTF-8.

        Reviewed by Simon Fraser.

        While updating the style for animations, most of the time spent was pure calling overhead.

        This patch should reduce this a bit on ARMv7:
        1) Get the frame directly from the document instead of document->view->framview->frame.
        2) Inline RenderObject::animation(). This is just 3 loads, setting up the registers on the call
           site is more expensive than loading the values directly.
        3) Inline RenderElement::setAnimatableStyle(). It has only one call site and the call is mostly
           overhead.

        Reviewed by Simon Fraser.

        This is a revert of r155324.

        By forcing line-height to be normal, r155324 was forcing WebKit to inspect font metrics
        to determine the height of a line. This means that if a fallback font was required to
        draw a line of text, and the fallback font had a higher ascent than the primary font,
        the entire line of text would be pushed down. If we don't force line-height to be normal,
        then we use the line-height value instead, which short circuits this mechanism, thereby
        not pushing text down.

        No new tests (because this is simply a revert)

        Work towards having frames in the scrolling tree
        https://bugs.webkit.org/show_bug.cgi?id=133665

        Reviewed by Tim Horton.
        
        Optionally (based on Setting) create nodes in the scrolling tree for frames which
        contain async-scrollable content. This will be used on iOS/WK2 to support accelerated
        overflow-scroll in iframes. The setting allows for testing on OS X.
        
        The change breaks an assumption in ScrollingCoordinator/AsyncScrollingCoordinator
        that we're always dealing with the main frame, and changes logic in RenderLayerCompositor
        so that we can connect the scrolling tree across frame boundaries. RenderLayerCompositor
        maintains a m_subframeScrollLayersNeedReattach flag that gets set whenever we add or remove
        scroll-coordinated layers in the current frame. When set, after updating compositing
        layers we walk child frames, and, if they have scrolling nodes, re-attach them to the
        scrolling tree (which will find the new ancestor node).

        Improve CSSPrimitiveValue::customCSSText for ARMv7
        https://bugs.webkit.org/show_bug.cgi?id=133597

        Reviewed by Andreas Kling.

        On imgur, some script is updating some layout on timers and on scroll.

        It looks like CSSPrimitiveValue::customCSSText() is a little constrained
        by the instruction cache on ARMv7. This patch improve the situation a bit.

        First, the creation of the string itself is changed to go from two allocation to one.
        Previously, we would allocate a StringBuffer and adopt it. Now we allocate a StringImpl
        directly with the inline buffer.

        The second issue is that the compiler was generating a real copy constructor for every
        assignment of the "text" variable (likely because the variable span is so large).
        This was solved by moving the string creating into a separate function (to fix the span)
        and being careful with passing PassRef<StringImpl> around.

        Then there was the problem that the compiler was a little too aggressive with inlining
        which caused each "case" to repeat the same prologue and epilogue before formatValue().
        This was solved by adding formatNumberValue() with NEVER_INLINE to have the prologue/epilogue
        in a single place.

        On older device, that's about 3% improvement on style access. On modern ARM64/x86_64
        there is no noticeable difference.

        Document::updateStyleIfNeededForNode can get very expensive
        https://bugs.webkit.org/show_bug.cgi?id=133599

        Reviewed by Andreas Kling.

        When pages are querying their style, we first run through
        Document::updateStyleIfNeededForNode() to find if that particular node needs style recalc.

        The problem was that updateStyleIfNeededForNode() could get really expensive. For each node,
        it needs to check the whole parent chain to find if any needs style recalc.
        When web pages get a bunch of nodes and querying their style, we ended up going over a lot
        of nodes just to find there is nothing to do.

        This patch adds two tweaks to reduce the problem:
        First, before querying nodeOrItsAncestorNeedsStyleRecalc() we check if the Document is dirty at all.
        The other part is making nodeOrItsAncestorNeedsStyleRecalc() faster by removing useless elements check.

        REGRESSION: missing underline under CJK text
        https://bugs.webkit.org/show_bug.cgi?id=128145

        Reviewed by Darin Adler.

        This patch refactors the GlyphToPathTranslator which is used to find intersections of
        glyphs and underlines. It was modified to allow for querying these pieces of
        information:
        1) The extents of the glyph. This can be used to make the underlines skip an entire
        glyph, wholesale
        2) What kind of skipping behavior should be used
        3) The Path which represents the glyph
        There are three skipping behaviors:
        1) (SkipDescenders) The previous behavior
        2) (SkipGlyph) Make the underline skip over the entire glyph, using the extents() function
        3) (DrawOverGlyph) Make the underline plow through the glyph, ignoring any descenders

        Calculating which underlining behavior to use depends on what the base codepoint that
        originated that glyph is. This means that we have to map from glyphs to characters,
        something which is nontrivial to do. In order to solve this problem, this patch adds
        an optional vector to GlyphBuffer which represents the location in the original string
        from which a particular glyph originated. Then, when our WidthIterator code adds
        glyphs to the GlyphBuffer, we can include the extra information about where we are
        in the input string. Once this data is available, the GlyphPathTranslator can look up
        the base codepoint from which this glyph originates, and can run ICU functions on that
        codepoint.

        We can use the ICU ublock_getCode() function to find which Unicode block a particular
        codepoint comes from. If the codepoint comes from a CJK block, we will use
        DrawOverGlyph; otherwise, we will use SkipDescenders.

        Eagerly reify DOM prototype attributes

        Reviewed by Oliver Hunt.

        No new tests.

        This allows us to get rid of a lot of the additional overhead of pushing DOM attributes up into the prototype. 
        By eagerly reifying the custom getters and setters into the actual JSObject we avoid having to override 
        getOwnPropertySlot for all of the DOM prototypes, which is a lot of the overhead of doing property lookups on 
        DOM wrappers.

        (prototypeHashTableAccessor): Changed to pass along the VM.
        (AttributeShouldBeOnInstanceForCompatibility): We were being overly conservative in regard to touch events. 
        This caused us to store the touch event handler getters and setters on the JSElement instance, which caused
        us to override getOwnPropertySlot for every JSElement subclass.
        (InstanceOverridesGetOwnPropertySlot): This was being overly paranoid about generate a getOwnPropertySlot if
        there was going to be a "constructor" property, even though we handled this in another place already.
        (GenerateHeader): Generate a finishCreation for prototypes unless it's the JSDOMWindow. We can't correctly 
        handle the DOMWindow in this version of the patch because reifying the static properties requires a global object,

        This is quite annoying, since there doesn't appear
        to be any pattern to the offsets (or margins) given

        Reviewed by Anders Carlson.

        Revision 168397 introduced a new animated style of form controls. Part of
        it included extending the margins for the controls to take into account the
        focus ring that animates in from a large radius to a small radius. This
        caused two problems:

        - the incorrect margins broke many layouts
        - despite increased margins, there were still some areas
          that did not repaint correctly.

        Restore the old margins and (temporarily) turn off focus ring animation.
        Bad layout is much worse than a missing animation. Another benefit
        of this is that we will use less memory.

        Use C++11 lambdas to construct FileThread::Task objects
        https://bugs.webkit.org/show_bug.cgi?id=133079

        Reviewed by Darin Adler.

        Have FileThread::Task constructor take in a std::function<void ()>-like object
        as the second parameter. Much like with ScriptExecutionContext::Task, the idea here
        is to use inlined C++11 lambdas in FileThread::postTask() calls. Because FileThread::Task
        also requires an instance pointer, a brace-init list is passed to these calls, passing
        in the instance pointer as the first parameter and the C++11 lambda as the second.

        FileThread::postTask() now takes in a FileThread::Task rvalue and moves it onto the heap
        and into the queue.

        In AsyncFileStream.cpp, calls to FileThread::postTask() are updated to use C++11 lambdas.
        Uses of MainThreadTask are also replaced by C++11 lambdas. This modernizes the code and
        removes a lot of helper functions.

        FileThread::Task doesn't use CrossThreadCopier anymore. Instead, we manually produce
        thread-safe copies as necessary. At the moment this approach produces another copy when
        passing the freshly-copied object into the lambda, but this will be avoidable once we
        make C++14 and the lambda capture expression support mandatory.

        Indexed getters should return values directly on the PropertySlot.
        <https://webkit.org/b/133586>

        Make indexed getters more efficient by using PropertySlot::setValue()
        to pass the value directly back through the slot, instead of giving it
        a function pointer that JSC would then immediately call back through
        to retrieve the value.

        The function pointer approach would make sense if we did inline caching
        of indexed getters but since we currently don't, this is pure overhead.

        Reviewed by Simon Fraser.

        Hit testing for the new columns doesn't care about compositing but does still
        need a pagination layer set to work. The old column code didn't care about this
        because it was top down (and wrong). The new code lets each layer paint and hit
        test its own fragments, so having a pagination layer set suddenly becomes relevant
        for composited layers.
    
        The solution is to cache whether or not the pagination layer crosses a compositing
        boundary, and then to force call sites of enclosingPaginationLayer to pass an argument
        indicating whether compositing layers should be included. Typically painting wants to
        exclude them but hit testing wants to include them.

        Filter effects are not subpixel aware yet. They paint to integrally sized image buffers.
        In order to ensure that the content is rendered to the the same position on the filter 
        source context as if there was no filter, the repaint rects need to be adjusted to match with
        the internal filter snapping (enclosingIntRect).
        This is a temporary change until after filter effects get subpixelized.

        However, this changeset regresses RenderNameFlow clipping when the content is on subpixel position
        and filter effect is present. Instead of adding the failing test cases to TestExpectations, I removed

        Reviewed by Antti Koivisto.

        Unlike the other tree marking optimization, adding HasPseudoStyle() on an element style
        during style resolution must be conservative and not set the flag unless every other filter
        matched first.

        After r169547, the SelectorChecker was setting flags on HasPseudoStyle() during the pseudo
        element matching. If that passed but the remaining filter did not match, the element style
        could have the flag "FIRST_LETTER" while not being able to resolve a style for "FIRST_LETTER".

        When the layout code was creating the renderer, it would find the FIRST_LETTER flag on the main style
        and try to get the specific style for FIRST_LETTER. Since no rule would resolve for FIRST_LETTER,
        the style would be null and the code would be crashing when accessing its parameters.

        This patch fixes the issue by moving the style marking for pseudo element at the end of the matching.

        There were a couple places in RenderListMarker and RenderMenuList that were

        any of the associated code that initializes the TextRun (such as creating
        a RenderingContext if necessary).

        There is currently one more client of this code that needs to be fixed.
        This is in RenderThemeIOS::adjustMenuListButtonStyle(). However, fixing

        Reviewed by Andreas Kling.

        Previously, the quirks mode of :hover and :active were evaluated from the SelectorFragment
        in fragmentOnlyMatchesLinksInQuirksMode(). There were two problems with that approach:
        1) The FragmentGenerator optimizes out some filter when they always match or can never match.
           Those fragment should still qualify :hover and :active, but they were lost
           for fragmentOnlyMatchesLinksInQuirksMode().
        2) Explicitely listing every attribute of SelectorFragment in fragmentOnlyMatchesLinksInQuirksMode()
           was extremly fragile. When :not() and :-webkit-any() were added, we forgot to update the quirks
           exceptions.

        This patch moves the quirks mode exception code from the code generator to the Fragment generator.
        The useless filters are no longer ignored for the quirks, and we don't need to update the quirks mode detection
        with every change of SelectorFragment.

        It is inefficient and ugly, but that is how that quirks is defined. It is only a problem for compilation,
        execution time remains unchanged.

        Make pseudo element matching for style resolution more JIT friendly
        https://bugs.webkit.org/show_bug.cgi?id=133441

        Reviewed by Antti Koivisto.

        Sharing pseudo elements is a complicated mess shared between the SelectorChecker
        and the RuleCollector.

        For compiling pseudo element matching, it would be best if all the complexity could
        be moved to compile time instead of runtime. It is also preferable to keep the compiler
        independant of the RuleCollector implementation's detail.

        This patch is a first step toward that goal. The main objective here is to make
        "dynamicPseudo" completely internal to the SelectorChecker.
        This is mostly a mechanical change, it is likely PseudoElement matching could be simplified
        further but that is not attempted here.

        Test: fast/css/style-sharing-empty-rule-modification.html

        * css/ElementRuleCollector.cpp:
        (WebCore::ElementRuleCollector::ruleMatches):
        The condition regarding pseudo element matching has been moved into SelectorChecker::match().

        This creates an extra cost for querySelector(), but that should be fine since the vast majority
        of selectors are JIT compiled and never use SelectorChecker in the first place.

        (WebCore::ElementRuleCollector::collectMatchingRulesForList):
        The loop is changed such that the tree marking (Style::setHasPseudoStyle) could be moved
        to SelectorChecker.

        The conditions about the security origin for getMatchedCSSRules() and the empty style rules
        are moved prior to the call to ElementRuleCollector::ruleMatches(). This ensure we keep the same
        behavior of not adding the pseudo style for empty rules (this could also help with tree marking
        in general but empty rules are probably uncommon).

        There is one behavior change from making this loop simpler: the SharingRules and StyleInvalidation
        modes now update their ruleRange. It is useless but it is simpler.

        [MSE] Appends of overlapping sample data do not clear existing samples properly.
        https://bugs.webkit.org/show_bug.cgi?id=133435

        Reviewed by Darin Adler.

        Test: media/media-source/media-source-overlapping-append.html

        The MSE spec has a spec error in how it removes overlapping frames. The intention seems to be
        to check for overlapping samples only when the incoming sample increases the highest presentation time
        field. But due to a mismatch in the range of a sample, defined as [start, end), and the check, which 
        treats the end as inclusive, the overlapping check is almost never run.

        Add the sample comparison logic to match [start, end) ranges, and rename the existing check to differentiate

        getBBox() returns (0,0) when width or height is zero.
        https://bugs.webkit.org/show_bug.cgi?id=93290

        Reviewed by Philip Rogers.

        The SVG spec states that a width or height of zero for  rects, circles and
        ellipses is valid but disables rendering of that shape.
        In this case, getBBox() should return the actual bounding box of the element.
        Previously, WebKit always returned (0,0,0,0) rather than the
        correct bounding box. This patch fixes that. 

        Rects and ellipses both now follow the same behaviour where
        the fall-back code path is only used when the shape will render (e.g. not
        when a dimension <= 0).
  
        This necessitates calling calculateRadiiAndCenter for ellipses even
        when the calculated values will be discarded in the fall back code path.
        But calculateRadiiAndCenter is cheap and this avoids making changes 
        elsewhere to stop CG drawing a zero width (or height) ellipse.

        With the gradual migration of scroll offsets to floating point, we ended
        up with a fully floating point code path been event scroll deltas and
        setting scroll positions in the scrolling tree.
        
        With some input devices (e.g. Logitech scrollwheel mice), the scroll deltas
        come in with non-integral values, and that caused the scroll offset to be non-integral,
        resulting in fuzzy layer contents. So round the scroll position.

        Additional testing (by enabling manual tiling mode for all patterned

        where the last row and column would paint too much, which

        CSS JIT: add support for the pseudo classes :hover and :active
        https://bugs.webkit.org/show_bug.cgi?id=133295

        Reviewed by Andreas Kling.

        This patch adds compilation support for :hover and :active. The code generation of both of them is trivial,
        most of the patch is improving the infrastructure and safety.

        The document compatibility mode is moved to its own typed enum. This ensure the values are exclusives and
        the native type is known (unsigned char here). The values are changes to binary flags to take advantage of
        test-and-branch on ARM64 (not used explicitely, it is automatically generated by the MacroAssembler).

        The other important refactoring is the code updating the flags on RenderStyle::NonInheritedFlags.
        The code was duplicated in some places so it is move into its own function addFlagToElementStyleFromContext().

        The generators themself are very simple. First we check the quirks-mode exceptions, that is generally excluded
        at compile time because the conditions are almost never met, even in strict mode.
        Then we have two cases: style resolution and query selector. Almost everything is just function calls.

        Correct two problems:
        1. Add new logic to handle cues that are identical to existing cues, except
           that they cover a slightly later moment in playback. For example, a cue
           encoding device might emit a cue at 24 fps, with many of the cues containing
           the same content but covering only 1/24th of a second.
           
           Rather than hiding and displaying our cues at the cue encoding rate, we should
           simply continue to display the same cue as long as the content is unchanged.
        2. The cue "isEqual" logic for TextTrackCueGeneric improperly short-circuited the
           VTTCue isEqual logic. This was done to avoid a false failure due to the cue
           type being 'generic' rather than 'vtt', but incorrectly treated cues with
           non-matching text as equal.

        [iOS WK2] Fix behavior of position:sticky inside accelerated overflow-scroll
        https://bugs.webkit.org/show_bug.cgi?id=133334
        <rdar://problem/16462535>

        Reviewed by Tim Horton.

        When the scroll position changes in an accelerated overflow-scroll element, we have
        to update child nodes in the scrolling tree for position:sticky. That requires a
        more generic ability to update the scrolling tree after some arbitrary zoom or
        scroll. To do this, we need to know the current fixed position rect, rather than
        having it passed in.
        
        So make the fixed position rect available from ScrollingTree, and make it possible
        to get the current scrollPosition() from any ScrollingTreeScrollingNode.
        
        Also, implement updateLayersAfterDelegatedScroll() in ScrollingTreeOverflowScrollingNodeIOS,
        and have it update descendant layers.
        
        Finally, fix ScrollingTreeOverflowScrollingNode to use the correct rectangle for its
        constraints math, using the scroll position of the parent node if appropriate.

        vw/vh units used as font/line-height values don't scale with the viewport
        https://bugs.webkit.org/show_bug.cgi?id=87846

        Reviewed by Darin Adler.

        This patch moves the resolution of viewport units to style recalc
        time. Currently viewport units are left unresolved during style
        recalcs, which leads to many problems with viewport units. Moving the
        resolution will fix these problems, as well as reduce the plumbing
        that goes on.

        This patch touches a lot of files since the valueForLength functions
        no longer need a RenderView. The interesting changes are in:

        - CSSToLengthConversionData -> CSSPrimitiveValue: for moving
            resolution to style recalc time.
        - Length / LengthFunctions: no longer needs to know about viewport
            units.
        - FrameView -> Document -> StyleResolver: for scheduling style recalcs
            upon resize

        Note that getComputedStyle will now return pixel values when viewport
        units are used. This behavior matches Firefox and the css3-cascade
        spec.

        This is based on a Blink patch by timloh@chromium.org.

        Lists styled with SVG fonts are not rendered as expected
        https://bugs.webkit.org/show_bug.cgi?id=133198

        Reviewed by Simon Fraser.

        There were a couple places in RenderListMarker and RenderMenuList that were
        implicitly creating TextRuns by passing a String to a function which
        expected a TextRun. Because TextRun has a constructor which takes a single
        String and isn't marked explicit, TextRuns were being created without
        any of the associated code that initializes the TextRun (such as creating
        a RenderingContext if necessary).

        This patch marks the aforementioned constructor as "explicit" to discourage
        such behavior in the future.

        When removing the child of an object, the removeChild method should return the next element

        Fix the quirks mode selector matching of the pseudo classes :hover and :active
        https://bugs.webkit.org/show_bug.cgi?id=133063

        Reviewed by Antti Koivisto.

        Our implementation of the quirks mode of :active and :hover was very wrong. The only
        thing it was doing is verify the pseudo class is not the first selector of a fragment
        (which was conveniently the only thing that was tested :)).

        Since those pseudo class were only checking for the order of the filters, something like
            #target:hover
        would succeed because :hover is not the first simple selector, while
            :hover#target
        would fail.

        That behavior is also a problem for the CSS JIT as it is an implementation detail of SelectorChecker
        and compiling something like that with our out-of-order matching would be nonsense.

        This patch update the implementation to follow http://quirks.spec.whatwg.org/#the-:active-and-:hover-quirk
        Basically, the only cases that do not work in quirks mode are selectors composed only of "*, :hover and :active".

        To implement this behavior, I needed to be able to inspect a complete selector fragment, including
        what is before and after :hover/:active.
        To do that, I replaced the boolean isSubSelector by a pointer to the first selector of the fragment.
        When we need to match :active/:hover in quirks mode, we just go over all the selectors in the fragment
        to find one of the qualifying match type.

        This change updates the grid items' 'display' property after style
        resolution so that we match the specification (see section 4. Grid

        Since halfway values always round away from zero, negative and positive halfway values
        produce opposite rounding direction.
        This patch ensures that negative halfway values round to the direction as if they were positive.

        Use size variants and glyph assembly from the MATH data.
        https://bugs.webkit.org/show_bug.cgi?id=130322

        Reviewed by Chris Fleizach.

        This patch modifies the RenderMathMLOperator code to use the MATH table
        when one is provided in the current font on the <math> tag. More
        precisely, the MathVariants table is used to draw a size variant or
        a glyph assembly. The displaystyle attribute is not supported yet, so
        for now large operators are always assumed to be in display style. The
        MATH support does not work well with all platforms+fonts, so at the
        moment the default font-family on the <math> is not changed.

        Reviewed by Brent Fulgham.

        When the maximum cache limit is exceeded, I get a crash.
        This happens when deleting cache entries, because a reference to the url string object in the LRU list

        When the string is removed from the LRU list in makeRoomForNewEntry(), the string is deleted.
        Next, the string is accessed again to remove the url from the index, and we crash.

        This can be fixed by removing the string from the LRU list after it is removed from the index.

        Fixing the crash also revealed an infinite loop problem.
        If the url for some reason only exist in the LRU list, and not in the index,
        we will inifitely loop in makeRoomForNewEntry(), trying to remove this url from the cache, but never succeeding.

        Add support for minimal-ui directly into the Viewport configuration.

        ViewportConfiguration knows about two kinds of layout size in scrollview coordinates:
        -normal size
        -minimal ui size.

        Initially, the page is initialized with resetMinimalUI() and starts with a normal layout.

        At any time before the main resource is loaded, the Web page can update its viewport meta tag
        to include minimal-ui. The viewport configuration is updated immediately to reflect the minimal-ui
        layout size. Any layout after that takes minimal-ui into account.

        Reviewed by Geoffrey Garen.

        Fixed the bug by rolling out r156252.

        When the user taps on the status on facebook.com, the page focuses a textarea,
        which is then made momentarily invisible by setting display:none.
        The page then removes display:none later and expects the textarea to be still focused.

        With r156252, the focus is removed after the page sets display:none and the keyboard disappears.
        Since the focus is never reset on the textarea, the user can never type in anything.

        The specification may need to change here given that this (rather odd) behavior/expectation exists
        on one of the most popular websites on the Web.

        current. This patch ensures platformMakeCurrent is also called for
        the alternate code path, and, if it fails to make the context
        current, will destroy the context. Effectively, this makes both

        Element within flattened frame may update its scroll state during the layout phase of the wrong RenderView
        https://bugs.webkit.org/show_bug.cgi?id=133013
        <rdar://problem/16760154>

        Reviewed by David Hyatt.

        Fixes an issue where the scroll state of an element may be updated during the layout of the wrong
        RenderView. In particular, the scroll state of an element inside a CSS flex box in a flattened
        frame f is updated during the layout of the RenderView associated with the parent frame of f instead
        of during the layout of the RenderView associated with f.

        The layout machinery assumes that the scroll state of each scrollable element is updated before the
        completion of layout for its associated RenderView. Currently we have logic to defer updating the scroll
        state of a scrollable element until completion of recursive layout. For a page with a flattened frame, we
        defer such updates until completion of layout for all RenderViews along the ancestor frame hierarchy of
        each flattened frame regardless of the RenderView associated with the element that originated the
        deferred scroll state request. Instead, only the RenderView associated with the element that deferred its
        scroll state update should dispatch the scroll state update.

        [CSS Regions] Crash while painting block selection gaps in regions
        https://bugs.webkit.org/show_bug.cgi?id=132720

        Reviewed by David Hyatt.

        The fix for WebKit bug https://bugs.webkit.org/show_bug.cgi?id=131511
        allowed selection highlight to match the DOM selection when the start
        and end point of the selection were in different flow threads. In order
        to enable that, the selection was performed separately on view and
        render flow threads, considered selection subtrees.

        However, the start and end points for each selection subtree were computed
        by means of Range class but it is not always possible to construct a valid
        Range from two pairs of RenderObjects and offsets.

        This patch keeps the substrees approach but instead of storing the endpoints
        for each subtree in a Range and continuously extending the Range, it stores them
        using the already available SelectionSubtreeRoot class. After the end points are
        computed for each subtree and before processing the subtree selection, the end points
        are adjusted in a similar fashion as the one used in FrameSelection::updateAppearance(),
        to make sure we are passing the same expected information to the method implementing
        the visible selection processing.

        Text decorations do not contribute to visual overflow
        https://bugs.webkit.org/show_bug.cgi?id=132773

        Reviewed by Antti Koivisto.

        This patch creates a function, visualOverflowForDecorations, which computes
        how much visual overflow to add around a text box due to text decorations. Most of the time,
        text decorations are fully contained within the text box, so the result is usually 0.

        This function exists within style/InlineTextBoxStyle.cpp, which is an added file. This is
        so that it can be called from setLogicalWidthForTextRun() inside RenderBlockLineLayout.cpp
        and from RenderStyle::changeAffectsVisualOverflow(). The former case passes in the full
        InlineTextBox and the latter case just passes in a RenderStyle (because the InlineTextBox
        is unavailable.)

        Split scrolling tree ScrollingNodes into FrameScrollingNodes and OverflowScrollingNodes
        https://bugs.webkit.org/show_bug.cgi?id=133022

        Reviewed by Sam Weinig.

        In both the scrolling state tree and the scrolling tree, split the "scrolling nodes"
        into FrameScrolling and OverflowScrolling nodes.
        
        Move what was the "viewportSize" property onto the base class for the scrolling
        nodes, calling it "scrollableAreaSize".
        
        Make minimum/maximumScrollPosition() virtual so we can share more code (and there
        is more code sharing to be done in future).

        When support for solid colors on layers was added, a layer was considered a candidate
        for the solid color optimization without regard to whether it had descendent layers
        with "paintsIntoCompositedAncestor" requirements.
        
        Fix hasVisibleNonCompositingDescendantLayers(), renaming it to isPaintDestinationForDescendentLayers()
        and having it take into account whether descendent layers need to paint into an
        ancestor.
        
        Also, this test has to happen after those descendent layers have had their
        compositing state updated, so move the isSimpleContainerCompositingLayer() to
        a new updateAfterDescendents() function which is called from the various
        places we do compositing-udpate-tree-walks.

        This patch removes unnecessary integral snapping of inlines at layout time.

        The general rule of thumb of using round/floor/ceil at layout time is to not use them.
 
        When some computed values (x, y, width, height) get snapped during layout, while others don't,
        intersecting/measuring mismatches could occur and they could end up producing visual artifacts such as truncations.
        This patch also enables iframe content to be positioned on odd device pixel positions on retina displays.

        AX: iOS: using AXAttributeCacheEnabler is too slow for every accessibilityElementAtIndex:
        https://bugs.webkit.org/show_bug.cgi?id=133043

        Reviewed by Mario Sanchez Prada.

        iOS Accessibility code tries to improve performance by caching attributes when accessing
        elements through the platform API. However, those API calls can be used very frequently when 
        iterating elements. Creating the AXAttributeCacheEnabler object and tearing it down is proving
        to be the hottest code path in samples for accessibility access.

        We need to move the logic for enabling/disabling the attribute cache to a level that can make
        a more informed decision about when to enable/disable.

        Instead of storing a rarely-used repaint timer on every RenderBox, store one

        Renderers get a flag tracking whether they have a pending lazy repaint.
        This way we can avoid hash lookups in the common case.

        Reviewed by Eric Carlson.

        Change SourceBuffer::m_private into a Ref<>, and add an assertion to
        SourceBufferPrivateAVFObjC's destructor if its client has not been cleared.

        Eliminate unnecessary churn in MediaSourcePrivateAVFObjC by having the predicate
        functor take bare pointers, rather than a PassRefPtr.

        The underlying problem seems to be in WebAVStreamDataParserListener. RefPtrs were
        being created off the main thread to a non-thread safe ref counted class. In some
        situations, this would result in double decrementing the ref, which would cause an
        early destruction of the underlying object. Instead replace these RefPtr strong
        pointers with explicit weak ones. Ensure the parser and its delegate are not freed
        before the append operation completes by passing strong pointers into the async
        append operation lambda.

        There were a few places where we weren't null checking m_mediaSource before using it,
        and at least one place where we weren't clearing m_mediaSource.

        ASSERT_NOT_REACHED() in DocumentOrderedMap::get() when removing SVG subtree

        Fixes an assertion failure when removing an SVG element with a duplicate id.

        When removing an SVG element with id A we synchronously instruct each element that references A
        to find the first element with id A, call this N, from the document root and register itself to
        either receive subsequent notifications from N (say, there is another element with id A) or as
        waiting for an element with id A (say, N = nullptr; => we removed the last element with id A from
        the document). Because the elements that reference A perform this operation synchronously when
        removing an element they consult an transient state of the DocumentOrderedMap when querying for the
        element with id A.
    
        Without loss of generality, let E, E_1, E_2, and E_3 be elements, where E_1, E_2, E_3 are children
        of E in that order and E_1.id = E_2.id = A and E_3.href = #A (that is, it references an element
        with id A). Suppose we remove E then we remove E_1, update DocumentOrderedMap to decrement its count
        for id A, and notify E_3 to look for an element with id A. This leads to an assertion failure since
        DocumentOrderedMap expects to find an element with id A, E_2, but cannot find such an element when
        traversing from the document root because E was unlinked from the document root (i.e. E_2 is in a
        disjoint subtree).

        Fixes an issue where an SVG element may reference an arbitrary DOM element e before e finished being
        inserted in the tree.

        Currently when an SVG element A is inserted into a document we use document.getElementById() to find the
        element B it references (if any). If A is inserted before B and B has the same id as a later element in
        the document then A can find B before B is notified that its been inserted into the document (i.e. before
        Element::insertedFrom() is called on B). Instead, A should call document.getElementById() only after
        cessation of the insertion operation that inserted it to ensure that all inserted nodes (including B)
        processed their insertion-specific logic.

        No new tests.

        In JSDOMWindow::getOwnPropertySlot, we currently look for the property on the JSDOMWindow, 
        then we search the window's subframes for name getters, then we look in the window's prototype 
        chain. Apparently we were doing the lookup in this order to be compatible with Mozilla, but 
        Mozilla no longer implements this behavior. Instead, they do the lookup on the prototype before 
        looking for subframe name getters. We should change this to match Mozilla. This has the convenient 
        side effect of allowing us to cache lookups in the window's prototype chain.

        Clean up "has non-zero begin time" terminology in animations

        Reviewed by Tim Horton.

        Change the "non-zero beginTime" terminology in the platform CA animations
        code to "explicit beginTime": this flag really means that we explicitly set
        the beginTime of the animation, rather than let CA set the beginTime when
        committing the animation. This flag is used for animations with negative
        delay, and when pausing.
        
        The WKNonZeroBeginTimeFlag key was spread across PlatformCALayerMac and PlatformCAAnimationMac,
        so hide it behind getter/setter functions.

        Tiled scrolling indicator needs to take topContentInset into account
        https://bugs.webkit.org/show_bug.cgi?id=132940

        Reviewed by Simon Fraser.

        The tiled scrolling indicator needs to move down by the value of the 
        topContentInset. This patch makes that happen by caching the topContentInset in 
        the TileController. This does feel a little silly since there is already a 
        function called setTiledScrollingIndicatorPosition() on TiledBacking. However, it 
        was often the case that calling that function had no effect because m_coverageMap 
        had not yet been created, and then the information was lost. So instead, we cache 
        the value.

        Set TiledBacking’s copy of topContentInset whenever it changes for the FrameView.

            TileController relied on the tiling mode in TileCache to determine if it should use low-res
            tiles when zooming. Unfortunately, sometimes the tiling mode gets set to Zooming even though
            it's actually a pan. Thus we can end up with blurry tiles. Fix this by adding a new flag on
            TileCache that controls this behavior and have UIKit set it only when we have an actual zoom
            operation.

        [New multicolumn] Spin in RenderMultiColumnSet::repaintFlowThreadContent()

        Reviewed by Beth Dakin.

        On iOS, wikipedia pages can hang under RenderMultiColumnSet::repaintFlowThreadContent().
        It appears that computedColumnHeight is set to 0 in prepareForLayout, but layout never happens
        on the RenderMultiColumnSet in some cases, leaving the column height set to zero.
        This caused columnIndexAtOffset() to return bad values, which resulted in very long loops
        in repaintFlowThreadContent().
        
        This fix is a stop-gap.

        Subpixel layout: Change Element.offset* client* scroll* return type to double.
        https://bugs.webkit.org/show_bug.cgi?id=132895

        Reviewed by Simon Fraser.

        This patch changes Element.offset*, Element.client* and Element.scroll* APIs return
        type from long to double to match the latest CSSOM View Module spec[1].
        Element.offset* and Element.client* do return subpixel values from now on.
        Element.scroll* still return integral values as the scrolling code hasn't adopted to subpixel rendering yet.

        subpixelCSSOMElementMetricsEnabled setting is added to be able to turn this feature on/off
        from WK2 preferences. It toggles the return value from subpixel to floored integral.
        It does not change layout/rendering behavior.

        [CSS Regions] Assertion failure in some cases with inline blocks
        https://bugs.webkit.org/show_bug.cgi?id=132859

        Reviewed by Mihnea Ovidenie.

        The patch hardens the conditions when the region range caches are
        populated to avoid desynchronizations when objects move during layout.
        This is true especially in the case of the boxes found inside
        inline blocks, that get their range from the containing line.

        There is a new function |computedRegionRangeForBox| that will always
        return a region range for a box using a best effort algorithm. This should
        be used only when there's no need to cache region information.

        This change also allows better control over the lifecycle of the
        |RenderBoxRegionInfo| objects stored on the regions. We can now iterate
        over the full range of the box when cleaning up the region box info. The
        same applies for the width change detection function.

        WebKit2 on iOS needs to capture the main thread's floating point environment.
        <https://webkit.org/b/132755>

        Reviewed by Geoffrey Garen.

        For iOS, WorkerThread::workerThread() expects to be able to initialize the
        worker thread's floating point environment to be the same as the one in the
        main thread.  The FP env of the main thread is expected to have been captured
        in the mainThreadFEnv global.  On WebKit2 for iOS, we neglected to initialize
        mainThreadFEnv.

        We now introduce a FloatingPointEnvironment class that will encapsulate the main
        thread (aka "UIThread") fenv, and we'll call FloatingPointEnv::saveMainThreadEnvironment()
        from ChildProcess::platformInitialize() to ensure that the FloatingPointEnvironment
        singleton instance is initialized properly for WebKit2.

        In the ChildProcess::platformInitialize(), we also need to initialize the ARMv7
        FP env to support denormalized numbers.  We'll do this before calling
        saveMainThreadEnvironment().

        Reviewed by Benjamin Poulain.

        On iOS fixed-position layers would get clipped to the document rect,
        but with rubber-banding, we can now have a custom fixed postion rect
        that extends outside the document rect.
        
        Another issue was that we would un-composite fixed elements sometimes
        when scrolling fast, again because they could fall outside of the document rect.
        
        A final issue was that pinching could reveal parts of fixed elements that should
        lie outside the viewport, rather than clipping the layers.
        
        Fix by converting both call points to use viewportConstrainedVisibleContentRect()
        rather than viewportConstrainedExtentRect(). On non-iOS platforms these are
        the same, but on iOS viewportConstrainedVisibleContentRect() uses the
        custom fixed position rect, which is the correct rect to intersect with.

        In practice, the new DocumentFragment:
        1 - Can represent a single node that's missing various attributes the original Node had.
        2 - Can be an unwanted fragment of arbitrary depth when the replacement happens inside Mail.app

        SVG outline property is broken and inefficient
        https://bugs.webkit.org/show_bug.cgi?id=113666

        Reviewed by Dean Jackson.

        Patch by Erik Dahlström backported from Blink.

        "[SVG2] css 'outline' property should apply to svg elements 

        The 'outline' property was only partially working in SVG before
        this patch, this makes it work on text and text content child
        elements too. 

        This makes SVG render the outlines as part of the foreground paint
        phase.

        CSS JIT: reduce cost of computing backtracking height
        https://bugs.webkit.org/show_bug.cgi?id=132546

        Reviewed by Benjamin Poulain.

        Because compiler previously compute backtracking height for
        previous child fragment, by leveraging this, we can limit the
        `maxPrefixSize` for `computeBacktrackingHeightFromDescendant`.

        For example, consider selector "c>a>b>d>a>b e"'s descendant chain,
        "c>a>b>d>a>b".

        At the <a> position, we have matching pattern [b, a, d, b, a] and
        calculate the backtracking height by following method.

        pattern:    [b, a, d, b, a]
        candidate0:    [b, a, d, b]  => Not matched.
        candidate1:       [b, a, d]  => Not matched.
        candidate2:          [b, a]  => Matched against the pattern.

        At this time, first candidate0's pattern size is `pattern.size() - 1`.
        And get backtracking height from descendant 3, that is
        `pattern.size() - candidate.size()`, `5 - 2`.

        And next, at the <c> position, we calcucate the backtracking height
        for this pattern.

        pattern:    [b, a, d, b, a, c]
        candidate0:    [b, a, d, b, a]  => Not matched.
        candidate1:       [b, a, d, b]  => Not matched.
        candidate2:          [b, a, d]  => Not matched.
        candidate3:             [b, a]  => Not matched.
        candidate4:                [b]  => Not matched.
        candidate5:                 []  => Matched against the pattern.

        Then, we get the backtracking height, which is 6 (6 - 0).
        However, in the above case, we already know that attempts from candidate0
        to candidate1 always fail, since parts of these are already tested at
        the <b> position trial and we know they don't match.

        So in this case, we should start this computation from candidate2,
        such as,

        pattern:    [b, a, d, b, a, c]
        candidate2:          [b, a, d]  => Not matched.
        candidate3:             [b, a]  => Not matched.
        candidate4:                [b]  => Not matched.
        candidate5:                 []  => Matched against the pattern.

        We can start computation with candidate size
        `pattern.size() - previousChildFragmentBacktrackingHeight`.
        In this example, `pattern.size()` is 6 and
        `previousChildFragmentBacktrackingHeight` is 3, so candidate size is
        3, that is candidate2.

        Headers and footers need to take the inset into account, and they also need to 
        factor in the fact that the root layer moves around now too.

        The existing yPositionForRootContentLayer() is actually the right calculation for 
        the header layer. The root content layer wants that value, but pushed down by the 
        header height. Now there are static functions for both of them and the footer to

        Reviewed by David Hyatt.

        This patch changes text selection rectangle calculation from integral to device
        pixel snapping. It ensures that selection rect painting matches box boundaries for inline elements.
        Directional rounding (horizontal only atm) is moved out from Font class and now accessible
        to all the painting code. RTL snapping strategy is changed from floor to round to match ltr behavior.
        However this patch does not address all the integral snapping across inline elements. There are
        a few places where we still calculate enclosing rects where snapping is sufficient.

        https://bugs.webkit.org/show_bug.cgi?id=132698

        Reviewed by Eric Carlson.

        -[AVStreamDataParser appendStreamData:] can casue the main thread to hang when a
        large amount of media data is appended at once. Move the actual parsing of data
        to a background (synchronous) dispatch queue, and split SourceBuffer::appendBufferTimerFired
        into two functions, the latter of which will be called after the background queue
        completes.

        [CSS Shapes] Can't select content within the area of the floating box when clip-path is applied
        https://bugs.webkit.org/show_bug.cgi?id=131375

        Reviewed by Dirk Schulze.

        According to http://www.w3.org/TR/css-masking-1/, the clipped part of the element should
        not have pointer event dispatching. So add this logic to RenderBlock::nodeAtPoint. This
        fixes the bug as it disallows selection on any clipped parts.

        I implemented the proper selection for the various CSS box types and added testing
        for them. Also, I made and run performance tests for exposing mouse events over the
        clipped/non-clipped area, which results can be seen in bugzilla.

        [CSS Blending] Blending doesn't work if the parent stacking context is not a self painting layer
        https://bugs.webkit.org/show_bug.cgi?id=130891

        Reviewed by Dean Jackson.

        The stacking context layers having unisolated blending descendants should be able
        to create transparency layers or to become composited in order to restrict blending 
        content to accessing the information outside the current stacking context.
        Some layers are not self painting layers and these layers cannot crate transparency
        layers and cannot be composited, thus they are not able to isolate blending descendants
        when it's required.
        
        The solution in this patch is to make a layer isSelfPaintingLayer when
        it needs to isolate blending descendants (hasUnisolatedBlendingDescendants).

        Reviewed by Simon Fraser.

        Mac allows focus rings to change rendering over time. Expose this
        functionality to WebKit by having the rendering code detect that
        a focused element has asked to repaint itself, and also have
        the FocusController object remember how long it has been since
        an element was focused.

        This patch removes WebCoreNSCellExtras, since a better version is
        available in WebKitSystemInterface, and it was going to be cumbersome
        to port the code from there into WebKit.

        ChildNodesLazySnapshot::m_childNodes needs two heap allocations.
        <https://webkit.org/b/132616>

        This seems a bit silly, since ChildNodesLazySnapshot is always
        allocated on the stack.

        Change it to be a bool + a Vector instead of using the nullity
        as a presence indicator. This way we also don't end up with an
        out-of-line ~OwnPtr for the Vector.

        Adapt inline SVG sizing behavior to Firefox and Blink
        https://bugs.webkit.org/show_bug.cgi?id=132569

        Reviewed by Dean Jackson.

        This patch is ported from Blink CR 308992. Thanks to David Vest for helping
        with back porting his Blink patch. From the commit message:

        "The basis of this change is to map explicit width and height
        attributes to CSS properties, essentially promoting them to
        presentation attributes. Note that implicit "100%" width and height
        are not mapped.
        
        This enables us to remove the concept of "percentage intrinsic size"
        and rely on normal CSS rules to resolve percentage values.
        
        The change has been approved by the SVG WG and the spec is being
        updated. Minutes here:
        
        http://www.w3.org/2014/04/07-svg-minutes.html#item03"

        The new model was indeed approved by the SVG WG and is basically following
        the CSS 2.1 model for replaced elements.

        With this patch WebKit, Firefox and Blink have the same behavior for inline SVG.
        This is the first successful approach to unify the sizing behavior of SVG
        across UAs.

        Avoid triggering layer tree commits that touch the layer's boundsOrigin
        while the user is scrolling in the UI process.
        
        Fix the WKOverflowScrollViewDelegate to pass along an "inUserInteration"
        flag to the ScrollingTree to say that we're in the middle of a user interaction
        (and also to send a final non-interactive update). That gets passed along
        to the web process, and turned into "SyncScrollingLayerPosition" update.
        AsyncScrollingCoordinator::updateScrollPositionAfterAsyncScroll() consults
        this, and uses it to set a flag on the ScrollableArea to say that the scroll
        is a user scroll.
        
        RenderLayerBacking then makes use of this (in existing code, shared with WK1)
        to avoid triggering layer bounds setting. Instead, it now just calls syncBoundsOrigin(),
        which updates the GraphicsLayer without touching platform layers. This is necessary
        so that GraphicsLayer geometry is up-to-date (used for tiled layer visibility
        computations).
        
        Finally, a hack in GraphicsLayerCA::computeVisibleRect() is conditionalized
        for WebKit1 by checking the type of platform layer.

        Named element cache can become invalid during HTMLCollection::updateNamedElementCache()
        https://bugs.webkit.org/show_bug.cgi?id=132575

        Reviewed by Ryosuke Niwa.

        Make sure the named element cache object stays valid in
        HTMLCollection::updateNamedElementCache() while it is populating it.

        The method was previously creating and setting the cache first, and then start
        traversing the DOM tree to populate it. As a consequence, hasNamedElementCache()
        would start returning true before the cache is actually populated.
        The issue is that finding matches in the DOM tree can cause
        HTMLCollection::invalidateCache() to be called under certain circumstances and
        thus the named element cache object can become invalid while
        updateNamedElementCache() is populating it.

        To avoid the issue, this patch updates updateNamedElementCache() so that the
        named element cache map is set *after* traversing the DOM tree. This way,
        hasNamedElementCache() returns false while the cache is being populated and
        there is no chance of it being invalidated too early.

        [CSS Blending] Webkit-blend-mode fails for accelerated parent with overflow:hidden
        https://bugs.webkit.org/show_bug.cgi?id=126160

        When the isolating layer has overflow:hidden, it will create a descendant clipping layer
        (m_childContainmentLayer), which will restrict the bleding layer to reading the backdrop
        from the isolating layer.
        The solution in this patch is to forbid the isolating layer to create a descendant clipping
        layer and make all the children to get their own ancestor clipping layers instead.

        Reviewed by David Hyatt.

        When a float-avoiding element (such as overflow:auto) is flowed into a flow thread after a float, its 
        logical left is not set on its frameRect or its layer's topLeft, but is instead kept in its RenderBoxRegionInfo
        structure. In some situation, this causes paint rejection to kick-in because intersecting the layer's rect
        (which DOESN'T contain the logical left from the region info object) with the computed background rect 
        (which contains the logical left from the region info object) results in an empty rect.

        In case a box didn't have a range, getRegionRangeForBox was searching for
        the top-most unplittable ancestor. This is not correct in every case. It's
        possible to have a box with range that has children without ranges (e.g. an
        absolutely positioned inline box with shadow descendants).

        I've modified getRegionRangeForBox to search for the first ancestor that
        has a cached range and use that instead of looking for an unsplittable box.
        The range of the box is the region at the top of the box, clamped by the
        range of the ancestor. This will be correct all the time once all the layout
        systems are region range aware and are able to cache it.

        Top content inset: Margin tiles should not display in the inset area when pinned

        -and corresponding-
        <rdar://problem/16613039>

        Reviewed by Simon Fraser.

        Prior to this change, topContentInset was implemented by positioning 
        RenderLayerCompositor’s m_rootContentLayer based on the inset value. In order to 
        ensure that no content is displayed in the inset area when we are pinned to the 
        top of the page, we’ll have to take a different approach. In this patch, when you 
        are pinned to the top of the page, the m_rootContentLayer is positioned at (0,0), 
        much like it would be without an inset, but the m_clip layer IS positioned at (0, 
        topContentInset). Then for all y-scroll values between 0 and topContentInset, the 
        positions of the clip layer and the contents layer are adjusted so that the clip 
        layer approaches a position of (0,0), and the root layer approaches a position of 
        (0, topContentInset). This makes sure that any content above the top the document 
        is aways clipped out of the inset area.

        In order to achieve this, the scrolling thread needs to know about the 
        topContentInset, the clip layer, and the root contents layer.

        AsyncScrollingCoordinator::updateScrollingNode() now takes an additional parameter 
        for the clip layer. Also export the topContentInset symbol for UI-side 
        compositing.

        CSS JIT: optimize direct / indirect adjacent's traversal backtracking
        https://bugs.webkit.org/show_bug.cgi?id=132319

        Reviewed by Benjamin Poulain.

        Since adjacent backtracking stack reference is pre-allocated
        in prologue in http://trac.webkit.org/changeset/166834,
        clearing stack phase is not needed. So we can drop
        JumpToClearAdjacentTail from backtracking action and simplify
        backtracking handling.
        And optimize direct / indirect adjacent's traversal backtracking by
        using appropriate backtracking height.

        When solving adjacent traversal backtracking action,
        1) When there's no descendant relation on the right, traversal
        failure becomes global failure.
        2) When `tagNameMatchedBacktrackingStartHeightFromDescendant` ==
        `heightFromDescendant` + 1, the descendant backtracking starts with
        the parent of the current element. So we can use the current element
        and the backtracking action is JumpToDescendantTreeWalkerEntryPoint.
        3) Otherwise, currently we take the conservative approach,
        JumpToDescendantTail.

        NOTE:
        And if `hasDescendantRelationOnTheRight` is true and there's no child
        fragment on the right, the backtracking element register is not
        effective. So we should ensure that fragment doesn't use the
        backtracking element register. Such a fragment fulfills the following
        conditions. 1. tagNameMatchedBacktrackingStartHeightFromDescendant is
        always 1 (tagNames.size(), that contains only descendant fragment) 2.
        heightFromDescendant is always 0 (-- See
        computeBacktrackingHeightFromDescendant implementation) Therefore such
        a fragment's action always becomes
        JumpToDescendantTreeWalkerEntryPoint. So we can ensure that the
        backtracking element register is not used.

        [iOS WK2] Tiled layer content missing on pages with animated tiled layers
        https://bugs.webkit.org/show_bug.cgi?id=132507
        <rdar://problem/16765740>

        Reviewed by Tim Horton.

        Updating the tiling area of content TileControllers while
        CSS animations are running depends on GraphicsLayerUpdater
        triggering repeated layer flushes. With UI-side compositing, those
        flushes were happening, but nothing triggered RemoteLayerTreeDrawingArea
        to flush changes to the UI process.
        
        Fix by having RenderLayerCompositor schedule a flush, rather
        than just doing a flush, in response to GraphicsLayerUpdater.
        
        Also change the name of the GraphicsLayerUpdaterClient function
        to indicate that it suggests that a flush is required soon, rather than
        that the flushing has to be synchronous.

        Previously, -webkit-overflow-scrolling:touch would cause us to make compositing
        layers for any element that had overflow: auto or scroll on either axis. This
        created lots of backing store when not required.
        
        Improve this to only create compositing for scrolling when there is actually
        scrollable overflow. This makes things slightly more complex, because we can

        Don't always make backing store for -webkit-backface-visibility:hidden
        https://bugs.webkit.org/show_bug.cgi?id=132420

        Reviewed by Sam Weinig.
        
        Previously, -webkit-backface-visibility:hidden unconditionally created
        compositing layers with backing store. This results in high memory use
        on pages with this style applied to many elements (a cargo-cult "optimization").
        
        Fix by only having -webkit-backface-visibility:hidden create compositing layers
        if some ancestor has a 3D transform. That's the only scenario in which the
        element can be flipped around to reveal the back side, so the only time we need
        to do compositing for this property. In future, we could be smarter, and only
        consider 3D transforms in the current preserve-3d context.

        Fix handling of attributes prior to compiling shader
        https://bugs.webkit.org/show_bug.cgi?id=132430

        Reviewed by Dean Jackson.

        WebGL programs that called bindAttribLocations prior to compiling shader sources
        would perform the bind using the non-hashed symbol name, but would later create
        the attributes as hashed names. Consequently, the program would refer to
        attributes that were never actually part of any shader, resulting in some amazing
        display artifacts.

        This patch adds a dictionary of hashed symbol names so that we can tell the WebGL
        program the proper name that will be used when the shader is eventually compiled,
        allowing the WebGL program to link against the proper symbol after compiling and
        linking completes.

        [iOS WK2] Some accerated overflow-scroll doesn't scroll correctly
        https://bugs.webkit.org/show_bug.cgi?id=132375

        Reviewed by Tim Horton.
        
        We set the size of the scrolling layer (which becomes the bounds of
        the UIScrollView) to a non-pixel-snapped padding box size, but the
        size of the contents layer is an integral-snapped scroll size.
        This would result in a fractional difference between the two, which
        makes us thing that the element is scrollable when it really is not.
        
        Fix by setting the size of the scroll layer to pixel snapped client size,
        which is what we also use for scrollability computation.
        
        Added some FIXMEs in code that requires pixel snapping.
        
        Also use #if PLATFORM(IOS)/#else to bracket some code that never runs on iOS

        [GStreamer] Use GstMetaVideo

        Reviewed by Philippe Normand.

        In WebKitVideoSink we announce the usage of GstMetaVideo, but we do
        not use it when handling the video frames. This might break
        some decoders and filters that rely on buffer's meta, rather
        that in the caps structures.

        This patch enables the use of GstMetaVideo through the GstVideoFrame
        API. And it is used everywhere the buffer mapping is required.

        Also this patch changes to nullptr where zeros were used.

        Also, compile conditionally the video buffer conversion when it is
        ARGB/BGRA, since it is only required for the Cairo backend.

        JSProxies should be cacheable
        https://bugs.webkit.org/show_bug.cgi?id=132351

        Reviewed by Geoffrey Garen.

        No new tests.

        Whenever we encounter a proxy in an inline cache we should try to cache on the 
        proxy's target instead of giving up.

        This patch adds support for a simple "recursive" inline cache if the base object
        we're accessing is a pure forwarding proxy. JSGlobalObject and its subclasses 
        are the only ones to benefit from this right now.

        This is performance neutral on the benchmarks we track. Currently we won't
        cache on JSDOMWindow due to HasImpureGetOwnPropertySlot, but this issue will be fixed soon.

        ScriptExecutionContext::Task should work well with C++11 lambdas
        https://bugs.webkit.org/show_bug.cgi?id=129795

        Reviewed by Darin Adler.

        Instead of having classes that subclass ScriptExecutionContext::Task and override
        the performTask(ScriptExecutionContext*) method, have the ScriptExecutionContext::Task
        take in a std::function<void (ScriptExecutionContext*)>-like object trough the constructor
        which would contain the code currently kept in the performTask() methods.

        This enables inlining C++11 lambdas into ScriptExecutionContext::postTask() calls. For
        cleanup tasks, the Task object can be implicitly constructed by using the initializer list
        constructor with the first argument being the ScriptExecutionContext::Task::CleanupTask tag.
        The ScriptExecutionContext class remains non-copyable and now stores the passed-in invokable
        object in the std::function wrapper, along with a boolean member that indicates whether the
        task is of cleanup nature.

        REGRESSION (r167879): Heap-use-after-free in WebCore::RenderFlexibleBox
        https://bugs.webkit.org/show_bug.cgi?id=132337

        Reviewed by Simon Fraser.

        From Blink r154582 by <jchaffraix@chromium.org>

        This is a regression from the changes in OrderIterator. The issue is
        that we don't invalidate our iterator when a child is removed. This
        means that we could hold onto free'd memory until the next layout
        when we will recompute the iterator.

        The solution is simple: just clear the memory when we remove a child.

        Note that RenderGrid is not impacted by this bug as we don't use the
        iterator outside layout yet, but if we do it at some point the very same
        problem will arise, so the same treatment was applied to the class.

        [CSS Shapes] off-by-one error in Shape::createRasterShape()
        https://bugs.webkit.org/show_bug.cgi?id=132154

        Reviewed by Bem Jones-Bey.

        This is a port of a patch for a bug that was reported by and fixed in Blink by
        David Vest: https://codereview.chromium.org/237123002/.  Shape::createRasterShape()
        now consistently reports "end-point exclusive" intervals. Before the patch
        an entire row of pixels was above the shape-image-threshold, the interval's end
        index was reported as image.width. Now it's image.width + 1, which is consistent
        with the way the end index is reported if the last above threshold pixel is within
        an image row.

        Two existing tests were revised to account for this change.

        Wrap CSS length conversion arguments in an object
        https://bugs.webkit.org/show_bug.cgi?id=131552

        Reviewed by Andreas Kling.

        This patch introduces a class CSSToLengthConversionData to wrap the
        data required to convert CSS lengths to Lengths. This simplifies the
        plumbing that goes on whenever we need to resolve CSS lengths and
        makes it easier to update the arguments needed for resolving these (in
        particular adding a RenderView for resolving viewport units at style
        recalc time; removing the computingFontSize bool also appears
        possible).

        Note that the zoom argument, which was previously a float in some
        places and a double in others is now a float.

        This is a port of a Blink patch by timloh@chromium.org.

        No new tests, no behavior change.

        If a <footer> section is placed before the body, it renders AX row information and order incorrectly.

        Reviewed by Bem Jones-Bey.

        ShapeInterval now distinguishes between x1==x2 - isEmpty() and x1,x2 haven't been
        set yet - isUndefined(). Removed the ShapeInterval setX1() and setX2() methods, since
        they're no longer used.

        The polygon algorithm for computing excluded intervals now ignores horizontal
        edges. It also ignores edges whose lower vertex matches the top of the line, if
        the edge's Y direction is upwards (away from the top of the line). The rationale

        [CSS Regions] Fix getClientRects() for content nodes
        https://bugs.webkit.org/show_bug.cgi?id=117407

        Reviewed by David Hyatt.

        This patch modifies getClientRects() to return a list of fragments
        for a fragmented box instead of a single rectangle positioned inside
        the region where the box center would appear.

        The approach is to split the border box of the element in regions using
        the layout positioning. Then each fragment is mapped to the view coordinates
        and the result added to the list of rectangles. To preserve the originating
        region when mapping the fragment through the ancestor tree I've introduced
        the concept of a current region. The current region is stored inside a
        CurrentRenderRegionMaintainer object, created whenever an algorithm needing
        it needs to run. When the maintainer is destroyed, the cleanup is made
        automatically. The RenderFlowThread holds a pointer to this structure for
        easy access.

        SelectorCodeGenerator::generateElementIsNthChild() leaks the parent register :nth-child() is non-filtering

        Reviewed by Andreas Kling.

        In two cases, the parent register was never returned to the register allocator:
        -Non filtering selectors (the early return).
        -Non marking selectors (at the moment: only querySelector API).

        Unfortunately, generateElementIsNthChild() makes function call, which forces us to do this manual allocation
        of the parentElement register. Long term, I want RegisterAllocator and FunctionCall to have a special type for that.

        Calculate appropriate backtracking start height from the closest

        1. When backtracking start height equals to current height, we
        can simply jump to a descendant element check phase.
        2. When backtracking start height equals to current height + 1, we
        can simply jump to a descendant element traversing phase.

        We can apply this optimization to fragments with adjacent combinators.
        But, in the meantime, we start to implement it for a fragment with

        OrderIterator refactoring to avoid extra loops
        https://bugs.webkit.org/show_bug.cgi?id=119061

        Reviewed by Darin Adler.

        This patch removes order values Vector and use a Vector of pairs instead. The pairs are formed by a child
        (RenderBox) and the index of this child. In addition, OrderIterator code is simplified.

        It provides a helper class OrderIteratorPopulator, used for manipulating the Vector directly. Which allows to
        consolidate the code into a single implementation across flexbox and grid. OrderIteratorPopulator part is based
        on a patch from Blink r153971 by <jchaffraix@chromium.org>.

        Current implementation is O(number of children * number of order values). Now it will just do a sort operation
        and then a regular loop. So if you have different order values in a flexbox or grid the performance will
        improve.

        Comparing results of perf-tests:
        * Layout/auto-grid-lots-of-data: ~0.5% worse.
        * Layout/fixed-grid-lots-of-data: ~0.5% worse.
        * Layout/fixed-grid-lots-of-data (setting 100 different order values): ~50% better.

        Store the containing region map inside the flow thread

        Reviewed by Mihnea Ovidenie.

        The patch moves the containing region map inside the flow thread where
        it can be better handled in case the region chain changes and the map
        needs to be cleared.

        As a result of this move we are able to also cleanup the lines region
        information of a block flow when it is removed from the tree.

        ScriptExecutionContext::Task should work well with C++11 lambdas
        https://bugs.webkit.org/show_bug.cgi?id=129795

        Reviewed by Darin Adler.

        Instead of having classes that subclass ScriptExecutionContext::Task and override
        the performTask(ScriptExecutionContext*) method, have the ScriptExecutionContext::Task
        take in a std::function<void (ScriptExecutionContext*)>-like object trough the constructor
        which would contain the code currently kept in the performTask() methods.

        This enables inlining C++11 lambdas into ScriptExecutionContext::postTask() calls. For
        cleanup tasks, the Task object can be implicitly constructed by using the initializer list
        constructor with the first argument being the ScriptExecutionContext::Task::CleanupTask tag.
        The ScriptExecutionContext class remains non-copyable and now stores the passed-in invokable
        object in the std::function wrapper, along with a boolean member that indicates whether the
        task is of cleanup nature.

        When hit-testing, painting block selection gaps and searching for the node at a specific point inside a flow thread,

        [CSS Grid Layout] Implementation of the grid-template shorthand.
        https://bugs.webkit.org/show_bug.cgi?id=128980

        Reviewed by Darin Adler.

        This shorthand sets the values for the grid-template-columns,
        grid-template-rows and grid-template-areas, so the implementation
        tries to reuse as much available parsing functions as possible.

        The "parsingGridTrackList" was refactored to return a CSSValue and
        let the "parseValue" function to assign the property value. The
        "forwardSlash" operator is now valid when the track-list clause is
        part of a shorthand. The "parseValue" function checkouts that only
        additional clauses are allowed when processing shorthands; the
        grid-columns-rows-get-set.html tests was modified to verify this.

        The "parseGridTemplateAreas" was refactored too, in order to
        process single areas's rows. This is very useful for the
        gris-template secondary syntax, which mixes areas and rows values.

        Finally, the "parseGirdLineNames" function was modified as well by
        defining an new argument to concatenate head/tail custom-ident
        elements and ensure the identList is at the heading index, since
        it's now possible the parseList was rewound.

        The implementation of the grid-template shorthand tries first to
        match the <grid-template-columns> / <grid-template-rows> syntax,
        failing back to the secondary syntax if needed.  This approach
        requires to rewind the parseList but it produces a clearer code.

        Incomplete body painting when using blend modes
        https://bugs.webkit.org/show_bug.cgi?id=131889

        The incomplete painting was caused by the transparency layer created for
        the root renderer. We can safely skip creating this transparency layer at
        the root level, as there is nothing else being painted behind this layer that
        could be used erroneously as a backdrop.

        Changed how JSCustomMarkFunction generation works. Instead of leaving out
        the generated visitChildren function, just generate a call to visitAdditionalChildren.
        This eliminates the need to repeat boilerplate.

        The fix for the above bug was to correct mistaken logic where JSSVGElementInstance
        had a visitChildren that did not properly mark event listeners because it explicitly
        did not call through to the base class visitChildren. The new arrangement makes that
        mistake impossible.

        I also had to disable the layout state to stop asserts on repaint when the children
        get moved. Not sure why Blink didn't hit this, but it's simple enough to add a
        LayoutStateDisabler to stop the assert.

        Patch collectFragments to know how to recur to collect ancestor fragments
        in order to apply nested splitting as you cross pagination boundaries.

        well. This is needed to fix intersectsDamageRect so that it doesn't grab
        the wrong bounding box when checking inline layers that are paginated.

        Reviewed by David Hyatt.

        Insert a break at end of content on our own in the multicol code, to make sure
        that overflow is accounted for, and also to make sure that we account for all
        content in non-final sets (i.e. those preceding spanners).

        In other words, this will additionally fix balancing issues in sets preceding
        a spanner. Added a test for that.

        https://bugs.webkit.org/show_bug.cgi?id=131949

        Reviewed by Darin Adler.

        The regression was caused by two bugs:
        1. The event didn't stop propagating itself even when it should.
           If the related target is same as the event origin, the event propagation should stop when the event reaches
           the root of the related target's tree scope. Otherwise, it should stop when it reaches the related target.

        2. Mouse event's related target exposed nodes inside a user-agent shadow DOM when the related target appeared
           inside the origin.

        Fixed the bugs by re-introducing path shrinkage algorithm removed in r157328 into EventPath::setRelatedTarget
        and adding an algorithm to determine the least common ancestor of the related target and the current target
        in moveToParentOrShadowHost. The latter algorithm doesn't match the shadow DOM specification:
        http://www.w3.org/TR/2013/WD-shadow-dom-20130514/
        but it's good enough in terms of the Web exposed behavior as we don't support author defined insertion points.

        REGRESSION (r151839): Subframe keeps getting mousemove events with the same coordinates after hiding a hovered element.
        <https://webkit.org/b/131974>
        <rdar://problem/15907469>

        When the currently hovered element disappears as a result of style recalc,
        we send a fake mousemove event to the page, to see if anything newly added
        should become hovered.

        The faking mechanism lives in EventHandler and simply synthesizes a new
        mousemove event using the last seen mouse location.

        The problem here is that we were sending this fake mousemove event to the
        subframe where the hovered element lived. Since subframes aren't kept up
        to date on recent mouse locations, this could cause some strange behavior
        where a subframe would dispatch mousemove events with stale coordinates.

        The solution is to always dispatch fake mousemove events from the main
        frame's event handler. This is how real event delivery happens, and hit
        testing will then find the appropriate subframe, if any.

        [CSS Regions] Selection highlight doesn't match DOM selection
        https://bugs.webkit.org/show_bug.cgi?id=131511

        Reviewed by David Hyatt.

        This patch implements a subtrees approach to fix selection interaction in CSS Regions.

        The idea is to divide the Render tree in subtrees. One subtree will be the RenderView (which is always present),
        then for each RenderNamedFlowThread (which are children of RenderView) we will have an extra subtree.

        For each subtree it determines the start and end positions according to the DOM tree. So, every subtree will
        always have a start and end position, and the selection algorithm will be able to reach the end from the start
        without problems (this allows us to remove the changes introduced in r155058).

        Then selection related methods in RenderView are adapted to ensure that they are called for each subtree. Making
        the selection highlight to match DOM selection as expected.

        Calling setNeedsLayout() is not sufficient when the topContentInset has changed 
        dynamically. We need to perform the layout right away and update the scrollbars. 
        This works completely when the inset changes due to entering/exiting fullscreen, 
        but I left a FIXME behind because it is possible to change the inset dynamically 
        just through the WK2 API and end up in a situation where everything looks right

        [New Multicolumn] Pagination mode messed up with non-inline axis and reversed direction.
        https://bugs.webkit.org/show_bug.cgi?id=131811

        Reviewed by Dean Jackson.

        Added fast/multicol/newmulticol/compare-with-old-impl/BottomToTop-tb.html
        
        With block axis pagination mode, it is possible to set a column height that is not the same
        as the available fill height for a block. The new multi-column code had the assumption that
        the column height was the same as the amount of fill room you had available. This is not
        the case.
        
        To correct the issue, I added a member variable to RenderMultiColumnSet that stores the
        available column height as a separate variable from the computed column height. This allows
        the pagination API to specify a different column height that is not the same as the view's
        content height.

        Even though it isn't involved in the solution, I also patched pageOrViewLogicalHeight on
        RenderView to work with the new column code as well.

        To address the layout test failures (that caused the previous rollout), I made sure to
        initialize m_availableHeight to 0 when m_computedColumnHeight also gets reset to 0.
        
        The assertion is not something I could reproduce on any machine, but I can see the problem.
        I patched Page's pageCount method to not have column code directly in Page.cpp, 
        and to make a new pageCount() method on RenderView that Page calls
        into. This method is now patched to handle the new column code as well as the old. I have
        no real way of testing this method though, since I can't reproduce the assertion that the
        bots were experiencing.

        We also don't need a function to return a static table.
        Ultimately I think we want a top-level WebKit object that
        hold the table, but for now use a global variable
        called UIStringTable. Since we're in an isolated world, we
        won't clash with anything.

        I noticed a few cases were we grab a localized string and

        Compile the :root pseudo class and fix a related issue with :nth-child()
        https://bugs.webkit.org/show_bug.cgi?id=131926

        Reviewed by Andreas Kling.

        Add the :root pseudo class. This is another trivial selector, we just need to compare
        the element pointer with the documentElement.

        I discovered some issues with :nth-child(n) through the layout tests for ":root".
        When the pseudo class nth-child could match anything, no code was generated. That decision
        was taken when generating the fragments.

        The specification of :nth-child() has two tests: the parent test and the counter test.
        Since some fragments would not generate any code for :nth-child(n), they would succeed on the root,
        which is incorrect since the root should fail the parent test.

        This was fixed by moving the filtering of non-counting :nth-child() after we generate the parent
        check.
        We still don't generate any counter test unless required.

        Implement blend modes with UI-side compositing.
        
        PlatformCALayer::setBlendMode() becomes pure virtual, and overridden in
        PlatformCALayerMac and PlatformCALayerRemote.
        PlatformCAFilters::setBlendingFiltersOnLayer() now takes a raw platform
        layer, so it can be called from the UI process on a CALayer*.
        
        Fix an issue with GraphicsLayerCA::LayerChange flags. 1 << 31 shifts
        a signed integer, so it ended up setting all the high bits in m_uncommittedChanges,
        causing us to push blend modes to the UI process for every layer. Fix by shifting
        an unsigned long long (1LLU << 31). This should also fix a build warning on Windows.

        Contents of directly composited image layers are sometimes missing

        RenderLayerBacking::updateGraphicsLayerGeometry() tested whether a
        GraphicsLayer had a contents layer to determine whether to call code
        that updates the contents rect. However, on Mac, we don't make a contents
        layer until later at layer flush time. That would result in an empty
        contentsRect being set.
        
        Fix by renaming GraphicsLayer::hasContentsLayer() to usesContentsLayer(),
        and on Mac consulting the m_contentsLayerPurpose flag, which is set
        at the appropriate time.

        No new tests since it's not web exposed.

        DOM timer throttling is currently part of the page throttler which uses per process 
        state and per page state to determine when to throttle.  This led us to being overly 
        conservative when turning DOM throttling off.  It should only respond to view state changes.

        Additionally since creating extra page throttlers SVG images caused bugs 
        in tracking state we'll reserve the page throttler for WebKit2 views.  To avoid regressing 
        WebKit1 we should move DOM timer throttling back to the page.

        When computing the repaint rect for absolute elements flowed into regions, the Y location of the
        region within the flow thread must no longer be added to the repaint rect's location because absolute
        positioned elements get pushed down through the regions by their absolute top. So adding the region's
        position in the flow thread and then adding the element's absolute top would cause us to add

        [New Multicolumn] Pagination mode messed up with non-inline axis and reversed direction.
        https://bugs.webkit.org/show_bug.cgi?id=131811

        Reviewed by Dean Jackson.

        Added fast/multicol/newmulticol/compare-with-old-impl/BottomToTop-tb.html
        
        With block axis pagination mode, it is possible to set a column height that is not the same
        as the available fill height for a block. The new multi-column code had the assumption that
        the column height was the same as the amount of fill room you had available. This is not
        the case.
        
        To correct the issue, I added a member variable to RenderMultiColumnSet that stores the
        available column height as a separate variable from the computed column height. This allows
        the pagination API to specify a different column height that is not the same as the view's
        content height.

        Even though it isn't involved in the solution, I also patched pageOrViewLogicalHeight on
        RenderView to work with the new column code as well.

        Make RenderLayerBacking get the timingFunction of the correct animation.
        https://bugs.webkit.org/show_bug.cgi?id=100632

        Reviewed by Simon Fraser.

        When an element has multiple animations that have different timingFunctions,
        the progress of each animation should be calculated using its respective
        timingFunction. But at this point, the timingFunction of the first animation is
        only used in RenderLayerBacking::startAnimation(), regardless of how many
        animations the element has.

        getAnimationFromStyleByName() was introduced in r89462 so that the
        timingFunction of the correct animation searched by its name would be
        used. This patch moves the function to KeyframeValue::timingFunction()
        so that RenderLayerBacking reuses this method.

        [New Multicolumn] columnNumberForOffset is not patched for new multicolumn code yet.

        Reviewed by Enrica Casucci.
        
        I took the opportunity to clean this code up while adding support for the new columns.
        columnNumberForOffset only applied for paginated RenderViews and was really about
        pages and not columns. It also only returns an actual page number if the columns are
        block progressed (e.g., right-to-left vertical Japanese books).
        
        Therefore I renamed columnNumberForOffset to pageNumberForBlockProgressionOffset and
        moved it to RenderView.
        
        I also renamed the member variable of SelectionRect to be pageNumber instead of
        columnNumber in order to make it more obvious that this isn't about columns per se
        (since the fact that we implemented RenderView's pagination mode using columns is an

        Reviewed by Darin Adler.

        When pagination mode is enabled, the full screen media will (depending on the width of the
        pagination columns) overflow its column, and hit testing will be clipped to the column. In extreme
        cases, where the column width < 0.5 * media element width, the media controls will be entirely
        unclickable.

        Rather than making the RenderFullScreen a child of the full screen element's parent's renderer,
        make it a child of the RenderView, putting it outside of the columns entirely. Always create and
        insert the fullscreenRenderer's placeholder, using it as the remembered insertion point for the
        fullscreen element's renderer when we exit full screen.

        [CSS Blending] Isolation descendant dependent flags are not updated correctly
        https://bugs.webkit.org/show_bug.cgi?id=130892

        Reviewed by Dean Jackson.

        The isolation descendant dependent flag (m_hasUnisolatedBlendingDescendants)
        will help us to determine if a layer should isolate blending descendants or not.
        The m_hasUnisolatedBlendingDescendants flag should be set for layers that have blending descendant layers
        not isolated by descendant stacking contexts.
        An element isolatesBlending() if it has this flag set and creates stacking context.

        Do not use the OverlapMap in RenderLayerCompositor::computeCompositingRequirements if the layer already

        is already supposed to be composited. 

        Also, added a bounding box of the overlap map, so that it can catch cases when the new layer is not overlapping

        Web Replay: memoize fallback time values for document.lastModified

        Reviewed by Joseph Pecoraro.

        If a document's Last-Modified header can't be found or used, then 
        document.lastModified is derived from the current system time or
        from filesystem data, which is obviously nondeterministic.

        It's better to handle this inside Document::lastModified rather than using
        MemoizedDOMResult, because only the fallback case is nondeterministic.

        Test: http/tests/inspector/replay/document-last-modified-fallback-value.html

        Reviewed by Gyuyoung Kim.

        Painting and compositing paths of WebKit-EFL were totally modified from r166768.
        However pixel dump codes still call deprecated functions like ewk_view_paint(),
        which causes that nothing is drawn.

        This patch adds new member functions to AcceleratedCompositingContext to support pixel dump.
        One of new functions is AcceleratedCompositingContext::extractImageData(),
        which replaces deprecated function calls. Besides the extractImageData() is invoked by
        ewk_view_screenshot_contents_get() in order to take the visible content displayed on the EFL webview.

        [New Multicolumn] Add support for column-span:all
        https://bugs.webkit.org/show_bug.cgi?id=129330

        Reviewed by Dave Hyatt.

        Column spanners are implemented as siblings of RenderMultiColumnSet
        objects (i.e. the regions for the column rows). This means that they
        are pulled out from the flow thread tree where they would otherwise
        live. This causes some complexity, most of which is contained within
        the multicol code.

        A placeholder is put in the flow thread tree where the spanner's
        renderer would otherwise live. This is needed in order make sure that
        we interrupt line layout before after the spanner. We also need this
        to be able to switch from one multicol set to the next.

        Some extra logic is required when dynamically inserting and removing
        flow thread descendants now, because we need to figure out if the
        renderer added should trigger creation of new multi column sets. If
        a spanner is inserted in the middle of a multi column set, we need to
        detect this, split the set and put the spanner in the middle.

        Wrote a bunch of tests. A few of the tests were copied from existing
        (old-impl) tests and put in a separate directory. That directory can
        be wiped when we turn on the new multicol implementation by default.

        Optimize Canvas fill and drawImage with SourceIn, DestinationIn, SourceOut, and DestinationAtop using transparencyLayer.
        https://bugs.webkit.org/show_bug.cgi?id=79659

        Reviewed by Darin Adler.

        Optimize fill() and fillRect() operations in Canvas on composited contexts by
        10 to 20 times on CG.

        Replacing the ImageBuffer code by transparency layers allows the
        graphics library to optimize the drawing.

        Doing the same for drawImage() would give performance regressions.

        An inline function will create a transparency layer for CG. Cairo graphics
        does not composite correctly when a transparency layer gets created. 
        The inline function is just a NOOP for Cairo.

        This fixes bug 131303 as well.

        While working on the patch, I discovered some severe issues with the parsing of large

        the values are parsed as a double then converted to an AtomicString for CSSSelector.

        There are many problems related to large values but we never got bug reports because
        they are very uncommon. Fixing those problem would require changing the parser.

        Here, CSSSelector::RareData::parseNth() is hardened a little bit to avoid absurd values

        original document to disk as it might be running in a process that
        either can't write to disk or can only write into a sandboxed
        container. To account for this, we need to separate the concern of
        quick look conversion from that of original document saving so that
        each activity can run in the appropriate process.

        Created a new interface between WebCore and WebKit by adding a client
        (QuickLookHandleClient) to QuickLookHandle which is notified of incoming
        bytes. A new function on FrameLoaderClient tells WebKit when a new
        QuickLookHandle is created, giving WebKit the opportunity to register a
        handle client. Moved the existing file system-related code as well as
        code only needed by WebKit1 in QuickLookHandle into a new WebKit1
        QuickLookHandleClient subclass.

        Make NodeList.length inline-cacheable by JSC.
        <https://webkit.org/b/131579>

        For objects with custom index or name getters, we have to make sure
        that builtin properties take precedence. We do this by scanning the
        ancestor chain for a suitable property slot before moving on to
        named items.

        With this patch, we now mark such builtins as cacheable. This is
        safe since the whole point of doing this before processing named
        items is to ensure the same slot is returned consistently.

        Clear sibling floats while splitting inline flow
        https://bugs.webkit.org/show_bug.cgi?id=130905

        Reviewed by David Hyatt.

        This is a port of a Blink patch by kenrb@chromium.org.
        (https://src.chromium.org/viewvc/blink?revision=169658&view=revision)

        During RenderInline::splitFlow(), floats are cleared on an anonymous
        containingBlock() for the inline being split. This is a problem if
        siblings of the block contain references to the same floats, since the
        float removal code in markSiblingsWithFloatsForLayout() will not later
        find them.

        This change also affects RenderBlock::splitFlow() and
        RenderBoxModelObject::moveChildrenTo, since those are called in
        similar situations as RenderInline::splitFlow().

        JSMainThreadExecState::call() should clear exceptions before returning.
        <https://webkit.org/b/131530>

        Reviewed by Geoffrey Garen.

        Test: fast/dom/regress-131530.html

        Previously, JSMainThreadExecState::call() did not clear any pending
        exceptions in the VM before returning.  On returning, the
        JSMainThreadExecState destructor may re-enter the VM to notify
        MutationObservers.  This may result in a crash because the VM expects
        exceptions to be cleared at entry.

        We now change JSMainThreadExecState::call() to return the exception
        (if present) via an argument, and clear it from the VM before returning.

        As part of this change, I updated various parts of the code base to use the
        new API as needed.

          function for the purpose of notifying MutationObservers.  Change to
          call JSC::call() directly.

          This assertion is added here to verify that this contract does not
          inadvertantly change in the future.
        (WebCore::JSMainThreadExecState::JSMainThreadExecState):

        Web Inspector: Remove shared PageScriptDebugServer, create per-Page
        https://bugs.webkit.org/show_bug.cgi?id=131523

        Reviewed by Timothy Hatcher.

        Having a shared PageScriptDebugServer was causing issues when we called
        JSC::Debugger::clearBreakpoints() closing one inspector while another
        is open for another WebCore::Page in the same process. Having the same
        JSC::Debugger underlying multiple InspectorDebuggerAgent instances
        means that when clearBreakpoints is called, the real JSC breakpoints
        underlying other InspectorDebuggerAgent's get removed. When those
        InspectorDebuggerAgents attempt to remove their breakpoints they
        encounter unexpected issues.

        This entirely rebuilds PageScriptDebugServer to be per-Page instead
        of shared across all pages. So take this opportunity to move the
        file from WebCore/bindings/js to WebCore/inspector.

        We're ending up in RenderBlock::splitBlocks() with |this| ==

            moveChildrenTo could have moved |curr|. This is a mitigation and
            not really a fix against a class of tree craziness.

        Finally, before moving children from |fromBlock| to |toBlock|, ensure

        Web Replay: memoize plugin data for navigator.mimeTypes and navigator.plugins
        https://bugs.webkit.org/show_bug.cgi?id=131341

        Reviewed by Timothy Hatcher.

        Information about plugins and mime types is nondeterministic and can change
        at any time, whether by system events, browser settings changes, or
        triggered by script. To avoid interposing on all those code paths, just
        memoize the plugin data used by DOMPluginArray and DOMMimeTypeArray.

        This is less efficient than controlling mutations to the underlying PluginData
        of a Page, but that can be done later if better plugin support is desired.
        The point of this change is to make analytics trackers deterministic across

        [iOS] Media controls should resize as the user zooms

        REGRESSION (r165908): ~QuickLookHandle() tries to dereference a null ResourceHandle
        https://bugs.webkit.org/show_bug.cgi?id=131467

        Reviewed by Tim Horton.

        QuickLookHandle stored a ResourceHandle pointer in order to later
        retrive the URL of its firstRequest(), but after r165908 we no longer
        always have a ResourceHandle. Since firstRequest()'s URL is the only
        thing we need from ResourceHandle, store it directly rather than a
        ResourceHandle pointer. In the case where we create a QuickLookHandle
        from a ResourceLoader rather than a ResourceHandle, pass the loader's
        originalRequest(), which represents the same request as firstRequest()
        (i.e. the request after willSendRequest() but before redirects).

        Renamed performDrag to performDragOperation. This function is responsible for

        it matches AppKit, like the other dragging destination functions already do.

        [CSS Regions] Monolithic elements should not affect the layout of the content outside its region
        https://bugs.webkit.org/show_bug.cgi?id=130499

        Reviewed by David Hyatt.

        When performing layout on an element flowed into regions, its logical height must not be incremented 
        past the region's logical bottom for monolithic elements in regions different than the last region their containing
        block is fragmented into. This ensures that the following elements are correctly laid out 
        from the top of the next region.
        This change must also be applied to floats in order to prevent text from avoiding part
        of a float that did not actually made it into the current region, but instead overflowed
        the previous one.

        After fix for https://bugs.webkit.org/show_bug.cgi?id=130392, we compute the region ranges
        information for inline elements collected in named flows with associated region chains.
        The algorithm for this computation, implemented in RenderFlowThread::getRegionRangeForBox,
        walks up the render tree trying to find the top-most unsplittable box under the named flow
        in the case where the region ranges information is not available.

        As this traversal works properly only when the starting box is not detached from the render tree,
        i changed the named flow information clearing in RenderBlock::collapseAnonymousBoxChild

        However, the code failed to update this transform when passing over
        GraphicsLayerCAs with no uncommitted changes, which caused us to choose
        an incorrect contentsScale sometimes, resulting in blurriness.

        [New Multicolumn] Child top margin sometimes ignored for column balancing
        https://bugs.webkit.org/show_bug.cgi?id=122754

        Reviewed by David Hyatt.

        We need to set zero page logical height in LayoutState when column
        height is unknown (when the columns haven't yet been
        balanced). There's code that assumes that non-zero page height means
        that page height is known. Lying about this makes the pagination code
        believe that every top margin is adjacent to a column break, which
        makes it eat and ignore all top margins.

        This should be cleaned up, but it's easier to wait until the old
        multicol code has been removed.

        EFL and GTK ports have managed own client of NavigatorContentUtils though it is only passed to
        NavigatorContentUtils. The NavigatorContentUtils has used the client to call port functions. So,
        there is no reason port implementation needs to manage the ownership. To manage the client is
        unnecessary work in current implementation.

        Web Replay: detect possible replay divergence from unexpected DOM event dispatches
        https://bugs.webkit.org/show_bug.cgi?id=131193

        Reviewed by Andreas Kling.

        Add assertions to catch potential nondeterministic behavior.

        The assertion added by this patch catches dispatched DOM events
        that are triggered by nondeterministic event loop cycles. If we
        did not capture an event loop input in the current event loop
        cycle nor are we manually simulating an event loop input during
        playback, then DOM events fired during the unordered cycle could
        run JavaScript and diverge the execution.

        During playback, we can assert that EventLoopInputDispatcher is dispatching
        when a DOM event is be dispatched to a document that is being replayed.

        During capturing, event loop inputs are captured rather than
        dispatched, so we add some accounting to track what caused a DOM
        event. To approximate the extent of computation triggered by an
        event loop input, we add RAII helpers to call sites where event
        loop inputs are captured.

        The assertions are disabled by default until the most common
        sources of nondeterminism are handled and playback errors are
        gracefully surfaced to the user. <https://webkit.org/b/131279>

        No new tests. This patch adds extra assertions for debugging purposes.

        https://bugs.webkit.org/show_bug.cgi?id=131292

        Reviewed by Andreas Kling.

        For historical reasons, changing the node flags was always done with function calls.
        This patch changes those calls to modify the nodes directly.

        [CSSRegions] Use RenderRegion::isValid() before using a region
        https://bugs.webkit.org/show_bug.cgi?id=131232

        Reviewed by Andreas Kling.

        RenderRegion method isValid() should be used to test whether a region
        is good to use instead of a mix between isValid() and flowThread().
        When the region is designed to fragment content from a parent flow thread,
        the m_flowThread is not nullified anymore, thus ensuring the same treatment for all invalid
        regions.
        Covered by existing regions tests.

        Both are extremely similar to :first-child. There are only minor differences:
        -:last-child has an additional check for the flag IsParsingChildrenFinished.

        Rework CSS calc logic, fixing some reference count mistakes in Length
        https://bugs.webkit.org/show_bug.cgi?id=131280
        rdar://problem/16400823

        Reviewed by Andreas Kling.

        New unit test in TestWebKitAPI.

        Changed the classes related to CSS "calc" to make the code a bit easier to read by
        moving code out of class definitions. Also used final some more, made more things private,
        used references instead of pointers, and other such changes. Biggest change, though, is to
        Length, which had a broken system for managing reference counted calculated objects.
        There were multiple bugs including a basic design mistake of not having a reference count
        and trying to use the reference count in the object itself. Fixed and covered by the unit
        test now; test found multiple problems in both the old and new implementations.

        * WebCore.exp.in: Updated exports, including symbols to make the unit test practical.

        * WebCore.xcodeproj/project.pbxproj: Made CalculationValue.h a Private file so it can
        be used in a unit test. Also let Xcode update the file type for a gperf file.

        * css/CSSCalculationValue.cpp:
        (WebCore::CSSCalcValue::equals): Updated since m_expression is a Ref now.
        (WebCore::CSSCalcValue::clampToPermittedRange): Marked inline and updated for data member
        name change.
        (WebCore::isIntegerResult): Changed argument order to put the operator first and use
        references instead of pointers. Also marked inline.
        (WebCore::createBlendHalf): Added. Helper to make the other functions more readable.
        (WebCore::createExpressionNode): Made non-member function private to this file. Also made
        many small improvements.
        (WebCore::CSSCalcValue::create): Updated so both of these call the same constructor.

        * css/CSSCalculationValue.h: Cut down CSSCalcValue class by making more things private
        and deleting unneeded things. Also use Ref instead of RefPtr.

        * css/CSSComputedStyleDeclaration.cpp:
        (WebCore::getPositionOffsetValue): Use isFixed function instead of type function.

        * css/CSSGradientValue.cpp:

        one from the base class. Changed the casting functions to work on references instead of pointers.
        Tweaked name of some members.

        * platform/Length.cpp: Reworked the CalculationValueMap (formerly CalculationValueHandleMap) to
        use unsigned instead of int, and store reference counts in the map rather than trying to share the
        reference count of the underlying CalculationValue object, which can lead to storage leaks where
        handles end up in the map permanently.
        (WebCore::calculationValues): Use NeverDestroyed instead of DEPRECATED_DEFINE_STATIC_LOCAL.
        (WebCore::Length::Length): Updated some data member names.
        (WebCore::Length::calculationValue): Updated to return a reference instead of a PassRefPtr.

        (WebCore::Length::nonNanCalculatedValue): Updated to use a reference instead of a pointer.
        (WebCore::Length::isCalculatedEqual): Updated since this is now only called if both objects are

        * platform/Length.h: Moved most functions out of the class definition to make the class definition
        easier to read. Reworked the constructors and assignment operators to handle the reference counting
        correctly. Added various FIXMEs and assertions. Removed some unused functions, made others private.

        Reviewed by Timothy Hatcher and Simon Fraser.

        To capture and replay scrolling, the scrolling coordinator will force synchronous 
        scrolling during capture and replay. If the page is capturing or replaying,
        ForceOnMainThread will be added to the coordinator's SynchronousScrollingReasons.

        A callback was added to signal that replay session state have changed,
        and thus the synchronous scrolling reasons should be recomputed.

        Automated replay reftests for scrolling are not included, because they will be
        too flaky until more nondeterminism is handled. Specifically, resource loading,

        [CSS Blending] Add compositing reason for isolation.

        Reviewed by Joseph Pecoraro.

        There are 2 reasons involving blend modes for a layer to be composited:
        1) the layer has blend mode and has composited descendants: CompositingReasonBlendingWithCompositedDescendants.
        2) the layer has to isolate composited blending descendants: CompositingReasonIsolatesCompositedBlendingDescendants

        [CSS Shapes] Simplify Polygon implementation
        https://bugs.webkit.org/show_bug.cgi?id=130975

        Reviewed by Andreas Kling.

        Only floats can specify shape-outside. For polygon shape-outside values, the problem
        of finding the left and right exclusion edges reduces to finding the X axis
        limits of the polygon edges that overlap a particular layout line. This is a much
        simpler version of the problem that PolygonShape was originally designed for, and so
        the implementation can also be simplified. There's more about the new algorithm in
        http://hansmuller-webkit.blogspot.com/2014/03/a-simpler-algorithm-for-css-shapes.html.

        [CSSRegions] Region's behaviour not updated when becoming valid from invalid
        https://bugs.webkit.org/show_bug.cgi?id=131211

        Reviewed by Andrei Bucur.

        When a region becomes valid again from invalid, it was part of a dependency cycle and the dependency cycle was broken,
        it needs to behave like a valid region again: if it has autoheight then it should compute its height based on the
        named flow content, if it has region styling then it should apply the additional style to the flowed content.

        Added a new method, updateRegionFlags, that is used to ensure that auto-height and region-styling flags
        are properly set in several situations. Checking the behaviour, autoheight or styling, is done only
        if the region is valid.

        Harden FilterOperation type casting
        https://bugs.webkit.org/show_bug.cgi?id=131142

        Reviewed by Sam Weinig.

        DefaultFilterOperation had an error-prone behavior where it set the base class
        OperationType to the type of some other filter class, but overrode isDefault(). 
        This made it very easy to write incorrect code that casted incorrectly based on type().
        
        Fix by making adding a DEFAULT filter operation type, and storing the represented
        type on DefaultFilterOperation().
        
        Also remove the OperationType argument for constructors of FilterOperations that
        can only be of one type, to avoid possible mistakes.
        
        Make the type cast macros a bit more normal, and use them in a few places.
        
        Fixed PlatformCAFiltersMac to handle the default filter case more cleanly.

        [CSS Shapes] CRASH with calc() value args in inset round
        https://bugs.webkit.org/show_bug.cgi?id=129816

        Reviewed by Andreas Kling.

        The code to parse the inset rounded corners was adding the parser
        value arguments to a temporary CSSParserValueList. Unfortunately,
        CSSParserValueList expects to own the values it contains, and it frees
        the values it contains when the list is destroyed. This was a problem
        because the values are owned by the CSSParserValueList passed in to
        parseInsetRoundedCorners, and thus the calc's argument list would get
        double freed, resulting in a crash. This patch fixes this by using a
        Vector to hold the pointers instead.

        <rdar://problem/15626368>

        Reviewed by Darin Adler.

        The setting Settings::maximumDecodedImageSize() and its related logic have various
        shortcomings, including the inability to cancel an image load when the estimated
        decoded image size exceeds the maximum decoded image size. In the iOS port, this
        setting is less useful given image subsampling support. For now, we remove this
        setting and its related logic. Should it turn out that such a setting is useful
        then we can implement it again taking care to address the shortcomings in the
        original design.

        Rather than calling the badly-named renderingContext() function on TextRun objects

        CSS JIT: compile the first-child pseudo class

        The reason to use a slow path is accessing renderStyle() is not trivial and this case isn't not

        (WebCore::SelectorCompiler::SelectorCodeGenerator::generateElementIsFirstChild):
        This is just implementing the test for first-child plus the tree marking. Nothing fancy,

        Also update the flags accessor to make them easier to work with from the compiler. In particular,
        setFirstChildStateFlags() sets both isUnique and firstChild. Currently the JIT does not need to access
        the value so individual flags are made private.

        The "updateForViewport" name didn't clearly reflect which of these

        [GTK] [TextureMapper] Weird brightness with some videos with acceletared compositing
        https://bugs.webkit.org/show_bug.cgi?id=130665

        Reviewed by Martin Robinson.

        When we uploaded a video texture to the mapper we were not
        considering that some videos could be decoded into a format
        without alpha component. Now we check if the video has alpha and
        if it does not, we remove the alpha flag when retrieving the
        texture from the pool. For this, the method to get the texture
        from the pool was modified to receive the flags, that is mapped to
        have alpha by default in order not to break any other existing
        code.

        Though we have a problem with AC in WTR and that makes it
        currently not testable, no new tests are needed because once this
        is fixed the current test set suffices to detect a possible
        regression in this.

            VisibleSelection::visibleStart() and VisibleSelection::visibleEnd()
            can both cause layouts, which has the potential to invalidate any
            rendertree-based objects. This was causing a problem in
            FrameSelection::directionOfSelection(), where a reference to a
            lineBox was being held across a call to visibleEnd().

            This patch ensures that the any layout is completed before linebox
            references are retrieved.

        Web Replay: add page-level setting to bypass the MemoryCache
        https://bugs.webkit.org/show_bug.cgi?id=130728

        Reviewed by Timothy Hatcher.

        When replaying a specific Page we don't want to store its cached resources in the
        MemoryCache. This patch adds a page setting to prevent the page's resources from
        being saved in the MemoryCache.

        If Settings::usesMemoryCache() is false, page resources are given the special
        SessionID bypassCacheSessionID(). The cached resource loader and memory cache
        act as if the memory cache is disabled if the resource has this special session id.

        Hook up ReplayController to override the memory cache setting during capture/replay.

        There are some form controls that change appearance

        can repaint the existing native control if necessary. At
        least ThemeMac was reusing a single control for painting
        all instances before this change.

        Since ControlStates is now a class, pass it around by
        reference.

        The other major change is keeping a timer to trigger a

        Inline JSDOMWrapper subclasses' finishCreation().
        <https://webkit.org/b/130890>

        finishCreation() is really a no-op for JSDOMWrapper subclasses in
        release builds. None of the ancestor classes do anything but assert
        in their implementations.

        Generate the function inline, reducing binary size, and removing
        an unnecessary call from the JSFoo::create() helpers.

        Reviewed by Eric Carlson.

        Some HLS streams will report incorrect naturalSizes due to the asset's preferredTransform
        property not being  available at the same time as the track's natural size. Given that
        AVFoundation only allows one video track to be selected at a time, simply use the asset's
        presentation size, cached in m_cachedPresentation size in all cases.

        Fix crash when RenderView is cleared inside of frame flattening layout

        Navigating on http://wallstcheatsheet.com pages on iOS in WebKit1 would
        sometimes crash when, inside the inChildFrameLayoutWithFrameFlattening clause,
        our frame's RenderView would be null after doing a layout from the root frame,
        possibly also when WebCore was being re-entered from another thread.
        
        Add a null check to fix this.
        
        Crash was timing-dependent and hard to test.

        When adding a new renderer to the tree we would search for the correct render tree
        position by traversing DOM children forward to find something that already has a renderer.
        In common case there is no such renderer. This would be repeated for each inserted renderer
        leading to O(n^2) in respect to child node count.

        [CSS Shapes] Remove shape-inside support
        https://bugs.webkit.org/show_bug.cgi?id=130698

        Reviewed by David Hyatt.

        CSS Shapes Level 1 (CR) only contains shape-outside. We are focusing our efforts on finalizing
        the implementation of shape-outside, it's worth to remove shape-inside code at this point for now.

        A list of reasons for the removal:
          - Shape-inside is only part of Shapes Level 2, which needs to be improved on some topics.
          - Shape-inside is lack of new shapes support (e.g. inset).
          - Deprecated shapes (r165472) are removed from the code (e.g. rectangle), which affects shape-inside. 
          - The current shape-inside code spreads across the layout code.
          - The current shape-inside implementation is experimental in some areas,
            and the partially implemented code can have security implications.
          - Removal of shape-inside opens possibilities for code complexity and performance
            optimizations for shape-outside. (e.g. simpler geometry code)

        No new tests are needed.

        [CSS Grid Layout] getComputedStyle() must return the specified value for positioning properties

        We were in some cases, adjusting the style in the StyleResolver
        (for example with two opposing spans) something that is now done
        in the RenderGrid because we cannot alter the original style.

        The code moved to the renderer became more self explanatory and it
        now supports named grid areas with names ending in "-start" and

        Reviewed by Tim Horton.

        Prepare for overflow scrolling via the scrolling tree by adding
        a new scrolling node type for overflow:scroll nodes. Mostly
        this is a new ScrollingNodeType that gets mapped to the same
        scrolling state nodes and scrolling nodes, but iOS creates
        state and scrolling nodes specific to overflow:scroll.
        
        Change the type checking on nodes to use virtual functions instead
        of just checking the node type, to allow the macros to work with

        InlineIterator position (unsigned int) variable can wrap around
        https://bugs.webkit.org/show_bug.cgi?id=130540

        Reviewed by Simon Fraser.

        We trigger an ASSERT that occurs when we are ignoring spaces (to collapse them
        into a single whitespace mark) but then encounter a line break. Because we don't ignore
        the first space (but do ignore subsequent spaces), when we hit a newline in an RTL context
        we want to ignore that first space as well (so as not to push the text away from the right
        edge). We do this by decrementing the InlineIterator pointing to this first space, so all
        the spaces get ignored. However, if that space is the first character in a Text node, the
        decrement will try to go past the beginning of the node, and trigger an ASSERT.

        This design is not great. At some point we should rework it to more elegantly handle
        collapsing whitespace in both RTL and LTR writing modes.

        This patch adds an ASSERT earlier in this codepath to catch potential problems earlier.
        It also pulls our sentinel value out into a separate boolean to make it more clear what is
        going on.

        Operator stretching: expose a math data API
        https://bugs.webkit.org/show_bug.cgi?id=130572

        Reviewed by Chris Fleizach.

        We expose a new SimpleFontData API to give access to the data from the

        missing FontPlatformData::openTypeTable function which will be necessary
        to load the OpenType MATH table. The changes are intended to be used

        toJS() and toJSNewlyCreated() still take an ExecState, that needs

        toThis() on a JSWorkerGlobalScope should return a JSProxy and not undefined
        https://bugs.webkit.org/show_bug.cgi?id=130554

        Reviewed by Geoffrey Garen.

        Fixed toThis() on WorkerGlobalScope to return a JSProxy instead of the JSGlobalObject.
        Added cast from JSProxy->target() if the jsCast<>() to the native object fails
        in toJSDedicatedWorkerGlobalScope() and toJSSharedWorkerGlobalScope().
        The original cast is needed for access to the local side of the worker, while the JSProxy
        cast is used on the remote side of a worker.

        Remove the call to flushCompositingStateForThisFrame() here. We should
        have always flushed before painting via other mechanisms in WebKit2 and WebKit2.
        Flushing during painting is actually harmful, since we could be inside

        Pseudo type cleanup part 2: split pseudo elements parsing
        https://bugs.webkit.org/show_bug.cgi?id=130370

        Reviewed by Andreas Kling.

        With this patch, pseudo elements are handled separately. The only thing left in
        the old path is compatibility pseudo elements and pseudo classes.

        The list of special pseudo elements is now separated and is stored in SelectorPseudoElementTypeMap.in.
        The script makeSelectorPseudoElementsMap.py takes that list to make the pseudo elements hash table.

        The other pseudo elements are the prefixed ones, they are filtered in CSSSelector::parsePseudoElementType().

        All the non-compatibility selectors are removed from SelectorPseudoTypeMap.in. CSSParserSelector::setPseudoTypeValue()
        is updated accordingly. The next step will be to clean that part.

        Optimize FEGaussian blur
        https://bugs.webkit.org/show_bug.cgi?id=50881

        Reviewed by Dirk Schulze.

        Currently boxBlur() will calculate the filter for each channel in
        a loop and also uses Uint8ClampedArray::set() to write the
        resulting pixels into destination array.

        Using Uint8ClampedArray::set() requires lots of unnecessary type
        conversions, not to mention other function calls. This patch
        updates the original written by Simon Fraser to apply cleanly to current
        trunk.

        It also implements code to handle EdgeModes and finally avoids use
        of ::set() in the newly added boxBlurAlphaOnly()
        function. Assignment of calculated pixel values rely on pointers.

        No new tests, no change on behavior.

        When the marker was placed for multi-column list items, it was being inserted
        into the list item itself. Even though the add code in RenderBlock did the right
        thing and put the marker inside the multi-column flow thread, the list item code
        passed in a beforeChild that was computed using the incorrect parent. This resulted
        in the flow thread being used both as the parent of the marker and the sibling of
        the marker.
        
        The fix is to add some code to RenderListItem to make sure it uses the multi-column
        flow thread if it exists both as the parent of the marker and as the basis for the
        computation of the sibling that the marker should be placed in front of.

        Change CodeGeneratorJS.pm special cases for "DOMWindow" to be general purpose

        Reviewed by Geoffrey Garen.

        Eliminated 'if ($interfaceName eq "DOMWindow") {' sections in CodeGeneratorJS where
        it was used to do DOMWindow specific casting to a JSObject, either a JSDOMWindow* or
        a JSDOMWindowShell*.  Instead the code generator will use the existing 
        JSDOMWindow* toJSDOMWindow(JSValue value) function based on a newly added attribute
        "CustomProxyToJSObject".  That attribute will emit a call to the function
        ${className}* to${className}(JSValue).

        This is being done to clean up the code generator and for a subsequent patch that
        will use a similar custom to{className} function for workers,
        JSDedicatedWorkerGlobalScope* toJSDedicatedWorkerGlobalScope(JSValue).

        Subpixel rendering: RenderBox is positioned off by one when non-compositing transform is present.

        Reviewed by Simon Fraser.

        div {
            position: absolute;
             top: 10.25px;
             left: 10.25px;
         }

         The <div> with (10.25px, 10.25px) is painted to (10.5px, 10.5px) after device pixel snapping on 2x display.
         Moving <div> to its own RenderLayer should not change the painting position.

         div {
             position: absolute;
             top: 10.25px;
             left: 10.25px;
             -webkit-transform: rotate(0deg);
         }

        When we paint the RenderLayer's content, the graphics context is translated by the rounded value of
        renderer's offset from parent.

            (10.25px,10.25px) -> rounded to (10.5px,10.5px).

        When the translate moves the graphics context's origin over the renderer's top-left position,
        the renderer's relative top-left coordinates end up being negative.

            Graphics context translated by (10.5px,10.5px) -> pushes renderer's relative top-left coords to (-0.25px,-0.25px)

        When we round (pixel snap) these negative coordinates, half-way values get translated to the wrong direction.

        (relative coords (-0.25px,-0.25px) -> pixel snapped to (-0.5px,-0.5px) -> final absolute(painting) coords (10px,10px))

        This patch changes the rounding to flooring to ensure that the relative top-left position never gets negative as the result
        of subpixel shifting.

        [CSS Shapes] clamp RasterShape shapeMargin to reference box size

        Reviewed by Dean Jackson.

        Corrected the way the maximum shape-margin value was computed for image valued
        shapes. The limiting case is an image with just one above threshold pixel. The
        largest possible value for shapeMargin is the radius of a circle that encloses
        the size of the shape-outside element's margin-box, since the shape-outside's
        boundary is clipped to the margin-box. The radius is just sqrt(2) * the margin-box's
        largest dimension.

        Also cleaned up up a few poorly named parameters.

        Implement contentInset for Mac WebKit2
        https://bugs.webkit.org/show_bug.cgi?id=130273

        Reviewed by Simon Fraser.

        This patch adds support for topContentInset(). If a page has a topContentInset(), 
        the root layer’s position is adjusted to account for the inset. It is assumed that 
        the area accounted for by the inset is visible but obscured, so scrollbars need to 
        be moved so that they only cover the non-obscured area, and most parts of WebCore 
        that wonder about visibleContentSize only care about the unobscured area, so this 
        patch makes that visibleContentRect return the unobscuredRect. Finally since this 
        is achieved by moving a layer’s position, the topContentInset() also needs to be 
        factored into various functions that are used to convert between coordinate 
        spaces. 

        Return Page::topContentInset() if this is the main frame.

        unobscuredContentRect() used to unconditionally return visibleContentRect() on 
        non-iOS platforms. Now that it is possible for some technically visible content to 
        be obscured, this code needed to be re-worked a bit to make some more sense. 
        visibleContentRect() now represents that visible content that is completely 
        unobscured, so it should call into unobscuredContentRect() rather than the other 
        way around.

        A completed fill-forwards animation should not disable overlap testing

        Reviewed by Dean Jackson.
        
        Previously, if -webkit-transform was being keyframe-animated, and the
        animation had fill-forwards, then we would continue to think that the
        animation is running and turn off compositing overlap testing. This
        caused some sites to keep too much backing store around.
        
        Fix by having isRunning{Accelerated}AnimationOnRenderer take some flags
        so that more specific questions about the running state can be asked.
        For layer creation, keep using the same criteria as before (for now)
        which includes paused and fill-forwards animations. For overlap testing,
        don't include the fill-forwards test.

        [CSS Blending] Blending operation is not isolated when setting z-index on parent from javascript
        https://bugs.webkit.org/show_bug.cgi?id=129307

        Reimplement the logic behind isolating blend modes. The blending operation should be limited to the

        [CSS Regions] The height of a scrollable element flowed inside a scrollable region is not computed correctly
        https://bugs.webkit.org/show_bug.cgi?id=129487

        Reviewed by Andrei Bucur.

        When propagating the layout overflow from the flowed element up to the flow thread itself,
        the region's logical bottom padding and the element's logical bottom margin must be taken into consideration.
        However, if the flowed element has overflow, the overflow will be painted over the region's padding
        and the element's margin, in order to be compatible with the non-regions case.

        Subpixel rendering: Nested layers with subpixel accumulation paint to wrong position.
        https://bugs.webkit.org/show_bug.cgi?id=130153

        Reviewed by Simon Fraser.

        Subpixels (fractional device pixels here) can accumulate through nested layers. Subpixels
        need to be propagated through the layer tree so that painting coordinates match layout coordinates.

        Subpixel accumulation through nesting (absolute positioning, 2x display):
        non-compositing case:
        (nested boxes)  (layout pos) (norm.paint pos) (translate accumulation, subpixel accumulation, final paint pos)
        div -> top: 1.3px   1.3px     1.5px      1.5px 0.2px -> snapped 0.0px -> 1.5px
         div -> top: 1.3px   2.6px     2.5px      3.0px 0.4px -> snapped 0.5px -> 2.5px
          div -> top: 1.3px   3.9px     4.0px      4.5px 0.6px -> snapped 0.5px -> 4.0px
           div -> top: 1.3px   5.2px     5.0px      6.0px 0.8px -> snapped 1.0px -> 5.0px

        compositing case:
        (nested boxes)  (layout pos) (norm.paint pos) (device pixel offset + fractional offset, final pos)
        div -> top: 1.3px   1.3px      1.5px      1.0px + 0.3px -> snapped -> 1.5px
         div -> top: 1.3px   2.6px      2.5px      2.5px + 0.1px -> snapped -> 2.5px

        <https://webkit.org/b/130458>

        Take a shorter path to the DOMWrapperWorld by using the passed-in
        global object instead of getting the lexical global from ExecState.
        Removed an old FIXME that no longer applies since JSObjects can
        always find the right global object these days.

        [CSSRegions] Compute region ranges for children of inline blocks
        https://bugs.webkit.org/show_bug.cgi?id=130392

        Reviewed by Andrei Bucur.

        Extend the region ranges computation for children of inline blocks.
        When we cannot retrieve the region range for a box using cached information,
        either from region range map or from the region cached on the RootInlineBox,
        try to find the top most unsplittable box up to the flow thread boundary.
        If we find such unsplittable box and the box has a region range, then return
        this range.

        Before this patch, method getRegionRangeForBox did not return true/false
        if it was able to retrieve the range and the caller checked the returned
        region values. I modified the method to return true if we were able to compute
        the range.

        [CSS Regions] Strange layout for content with region breaks
        https://bugs.webkit.org/show_bug.cgi?id=121318

        Reviewed by Mihnea Ovidenie.

        When break-inside: avoid is used on an element, the implementation tries to
        force it inside a single fragmentation container even though the descendants
        of the element specify forced breaks. This leads to unexpected results and
        unstable layout.

        The change extends the definition of unsplittable elements for flow threads
        using the same conditions found inside RenderBlockFlow::adjustForUnsplittableChild.
        This change forces elements that require break avoidance to have a single region
        in the region range. As a result, forced breaks have no effect inside them.

        It should be noted this may not the behavior defined by the CSS3 Fragmentation spec.
        From my understanding of the text, forced breaks override any avoidance specified
        by ancestor elements. However, implementing this is a larger change that will require
        a fundamental new approach in handling break avoidance. This patch just brings
        consistency to the API.

        If initial selection isn't set when we handle selection movement for accessibility, we need to set it. If we don't, using arrow

        Reviewed by Andreas Kling.

        Following <http://trac.webkit.org/changeset/163560>, SVG inline elements may be treated as block-
        level elements depending on their CSS styles (e.g. display: block). But such elements should always
        be treated as inline-level elements.

        Partially revert <http://trac.webkit.org/changeset/164368> as it addressed a similar issue for
        <tspan> and <tref>. Instead we should implement RenderSVGInline::updateFromStyle() to ensure that
        RenderSVGInline and any derived classes (e.g. RenderSVGTSpan) are always treated as inline elements
        regardless of their CSS style because the SVG text layout code depends on this assumption as part
        of a performance optimization. We may want to revaluate the benefits of this optimization with respect
        to code clarity and ensuring the code is less error prone.

        Mutating rules returned by getMatchedCSSRules can result in crash
        https://bugs.webkit.org/show_bug.cgi?id=130209

        Reviewed by Andreas Kling.
        
        The non-standard getMatchedCSSRules API returns CSSStyleRule objects that don't
        have parent stylesheet pointer (as we don't know which sheet the rule originated from).
        Mutating the rule via such wrapper can lead to crashes later as we fail to invalidate
        the underlying stylesheet.
        
        Fix by disallowing mutation of style rules that don't have parent sheet pointer. CSSStyleRule
        has two mutable properties selectorText and style. The latter gives back CSSStyleDeclaration.
        This patch disallows mutations in both cases for CSSStyleRules that don't have parent stylesheet
        pointer.
        
        While it is technically possible to have CSSRules that are legitimately disconnected
        from stylesheet (by removing rule from sheet while holding a reference to it) it never
        makes sense to mutate such rule as there is no way to do anything with it afterwards.

        HTMLInputElement::defaultEventHandler() shouldn't force style updates.

        Move the updateStyleIfNeeded() call down to TextFieldInputType instead
        of doing it for every HTMLInputEvent.

        There might be a better way to do this; we only want to know about this
        specific element's renderer, and don't need the rest of the tree.
        This is still an easy hack to avoid a lot of unnecessary work.

        * dom/Element.h: Removed the overload of hasLocalName that takes a
        QualifiedName and ignores the non-local-name parts of it. Callers should
        use hasTagName instead, now that it's optimized appropriately. Added
        overloads of hasTagName for all the specific qualified name types. It's
        more efficient to use the Node versions of these functions rather than
        using QualifiedName::matches to do the check. Removed the hasTagName and
        hasLocalName functions from the Node class; the only convenience functions
        needed in Node are the specific checks for tags from HTML, MathML, and SVG,
        not the general purpose ones.

        * dom/Node.h: Removed hasLocalName and replaced the single hasTagName
        that takes a QualifiedName with three faster ones that take HTML, MathML,
        and SVG qualified names instead. Also updated to use nullptr instead of 0.

        Reviewed by Simon Fraser.

        Rounded rectangle's radius needs adjustment after its containing rect gets pixel snapped.
        Keeping the old radius value could make rounded rectangle non-renderable, because the
        originally calculated radius length does not fit the snapped rectangle anymore.

        [CSS Grid layout] Initial position in span not correctly computed sometimes
        https://bugs.webkit.org/show_bug.cgi?id=130124

        Reviewed by Darin Adler.

        The code uses std::lower_bound() to get the first grid line
        position before a given resolved position in a Vector. That
        function returns an iterator pointing to the first value not
        "strictly less" than the given one. Consequently, the returned
        position might be actually located after the resolved final
        position. In those cases we need to select the previous position
        in the Vector (which is guaranted to be "< resolved position" due
        to how std::lower_bound() works).

        For example, if we have vector=[2,5,8] as grid positions, and we
        need the first position before 7, std::lower_bound(vector, 7) will
        point to 8 (first value not < 7). It's obvious that we should
        select 5 instead. Should the pointed value be equal, then we
        should do nothing, because the indexes mean tracks, so the item
        will be placed in just one cell of the grid.

        Reviewed by Chris Fleizach.

        This prepares the MathML stretchy code for future support for the MATH
        table. In particular, this uses the glyph index for measuring and
        drawing instead of Unicode code point since the MATH table uses glyph
        indices. Also, this merges the preferred width and stretchy character
        selection into one common path since they will also have to share the
        size variants measuring/selection. Finally, we expose a drawGlyphs()
        method so that we can draw a glyph by index.

        No new tests. This should not change the behavior of the stretchy code.

        Reviewed by Darin Adler.

        Currently Vibration is using two timers,
        one is to start a vibration and another is to check termination of a vibration.
        But they do not work in same time, if one of them is fired, then anothor will start.
        Thus this patch removes one of them, and manages vibration states by enumeration.

        Also, this patch implement the missing part of the algorithm,
        which check the maximum length of the vibration pattern and the maximum duration of the vibration.

        Lastly, this patch removes unused methods from Vibration.

        Using an XMLHttpRequest to download resources had a few issues. Being an
        Active DOM Object the load could be paused. Without an extra retain,
        when the load was cancelled (e.g. a page reload) the XHR would get
        destructed and could cause a crash if the list of active DOM objects
        was actively being iterated.

        Switch to a DocumentThreadableLoader to manage the load ourselves.
        This still uses the Memory cache, but we have a little more control.

        Optimize hasTagName when called on an HTMLElement

        Reviewed by Antti Koivisto.

        Added new hasTagName functions that have the efficiency of hasLocalName.
        but are safe.

        Now we can always use hasTagName, and we'll get a compile time error if
        we try to use an SVG tag name with an HTML element. All call sites that
        use the more specific tag name types are more efficient, and call sites
        that have a specific pointer type will get even more efficient checking
        that is exactly what we used to get by calling hasLocalName.

        overloads of hasTagName for all the specific qualified name types. It's
        more efficient to use the Node versions of these functions rather than
        using QualifiedName::matches to do the check. Removed the hasTagName and
        hasLocalName functions from the Node class; the only convenience functions
        needed in Node are the specific checks for tags from HTML, MathML, and SVG,
        not the general purpose ones.

        * dom/Node.h: Removed hasLocalName and replaced the single hasTagName

        This variable was the "parent" node where the style was being inherited from, not the actual parent.
        The code would also recompute it even though the call sites generally know the rendering parent already.

        If we consistently pass parent style to StyleResolver::styleForElement we won't need the variable and

        Subpixel rendering: Nested layers with subpixel accumulation paint to wrong position.
        https://bugs.webkit.org/show_bug.cgi?id=130153

        Reviewed by Simon Fraser.

        Subpixels (fractional device pixels here) can accumulate through nested layers. Subpixels
        need to be propagated through the layer tree so that painting coordinates match layout coordinates.
        
        Compositing case: (absolute positioning, 2x display)
        parent layer pos(0.3, 0.3) -> floored painting position (0, 0)
        child layer pos(10.2, 10.2) -> layout offset from parent (10.2, 10.2), 
        but the actual painting offset is (10.5, 10.5) as the result of parent flooring.
        
        Non-compositing case: (absolute positioning, 2x display)
        parent layer pos(0.3, 0.3) -> GraphicsContext is translated to (0, 0).
        child layer pos(10.2, 10.2) -> layout offset from parent (10.2, 10.2)
        but the GraphicsContext's offset is (10.5, 10.5) as the result of the parent's translate.   

        In both cases, without the subpixel adjustment, we'd paint the current layer at (10.0, 10.0)
        after flooring, while its painting position is actually (10.5, 10.5).
        Subpixels do accumulate through nested layers.

        The scrolledContentOffset method should handle the hasOverflowClip check
        https://bugs.webkit.org/show_bug.cgi?id=130028

        Reviewed by Antti Koivisto.

        Before this patch, every call to RenderBox::scrolledContentOffset was guarded by the
        hasOverflowClip check, because the scrolledContentOffset method would ASSERT(hasOverflowClip()).
        This was simplified by moving the hasOverflowClip check inside the scrolledContentOffset method
        and returning (0, 0) for elements that do not clip the overflow.

        No new tests needed, just a refactor.

        Web Replay: add infrastructure for memoizing nondeterministic DOM APIs
        https://bugs.webkit.org/show_bug.cgi?id=129445

        Reviewed by Timothy Hatcher.

        Add two pieces of infrastructure to support memoization of selected DOM APIs.

        The first piece is MemoizedDOMResult, a templated replay input class that knows
        how to serialize a DOM API's return value, ctype, and exception code.

        The second piece is the addition of a new IDL attribute called `Nondeterministic`.
        When placed on a DOM function or attribute, the code generator will emit code
        to save the DOM API's return value or use a memoized return value instead,
        depending on the current replay state. This new emitted code path is behind
        a feature flag.

        No new tests, as no new inputs are addressed by this change. Per-DOM API replay
        regression tests will be added when those APIs are marked as nondeterministic.

        Web Inspector receives spurious setScriptEnabled instrumentation calls
        https://bugs.webkit.org/show_bug.cgi?id=130147

        Reviewed by Timothy Hatcher.

        When page settings change, inspector instrumentation should only fire if
        the scriptsEnabled setting actually changes from the previous setting. But
        due to an unnecessary PLATFORM(IOS) guard, the inspector was being notified
        on every settings update even if nothing changed.

        This manifested as lots of Page.scriptsEnabled messages being sent to
        the inspector frontend as the Inspector window is dragged.

        Reduce memory use for static property maps

        Reviewed by Andreas Kling.

        Static property tables are currently duplicated on first use from read-only memory into dirty memory
        in every process, and since the entries are large (48 bytes) and the tables can be unusually sparse
        (we use a custom hash table without a rehash) a lot of memory may be wasted.

        https://bugs.webkit.org/show_bug.cgi?id=115787

        Reviewed by Chris Fleizach.

        This makes the <mo> operators use the lspace/rspace properties to
        determine their spacing. The spacing is now consistent with the one
        of <mfenced> and as a consequence bug 118843 is fixed. This also ensures
        that the rendering of <mo> elements is updated when the form or
        attributes are changed.

        Reviewed by Chris Fleizach.

        This patch continues the refactoring of token elements that has been
        started in bug 44208. The <mo> element now derives from the
        RenderMathMLToken class, which was already used for the <mi> element.
        The behavior of anonymous <mo> elements created by the <mfenced> element
        is now more consistent with the one of "standard" <mo> elements and the
        spacing around them is now handled in RenderMathMLOperator. This is a
        first step towards fixing bugs 115787 and 118843. The only visible
        rendering change is how <mfenced> open/close attributes handle
        whitespace and multiple characters and some tests are added for that.
        Other features are already covered by other tests. Finally, this also
        removes some code from AccessibilityRenderObject that was used to
        workaround issues with <mo> elements.

        Start splitting CSS Selectors's pseudo types
        https://bugs.webkit.org/show_bug.cgi?id=130003

        Reviewed by Andreas Kling.

        CSS Selectors pseudo types come in 3 flavors: page, pseudo class, pseudo elements.

        The three types are mixed together in a single enum list named PseudoType. Only some combinations
        of match type + pseudo type are valid, but this is implicitly defined from the code.

        This patch is the beginning of a refactoring to add more clear boundaries between
        valid and invalid combinations.

        First, the handling of page pseudo types is completely split from the other values.
        The parser use a different method for handling the value CSSParserSelector::parsePagePseudoSelector().

        PagePseudo types no longer store their string in the CSSSelector either to reduce the redundancy
        with m_pseudoType.
        When we need to generate the string for those CSSSelector, we recreate the string as needed in
        CSSSelector::selectorText().

        The remaining two types are not yet split in this patch but this introduce the preliminary clean up
        toward that goal.
        The list of parsed pseudo types is now generated at compile time from the source in SelectorPseudoTypeMap.in.

        * DerivedSources.make:
        The mapping of strings to pseudo types is generated from SelectorPseudoTypeMap.in

        TextIterator: Use StringView and references rather than pointers
        https://bugs.webkit.org/show_bug.cgi?id=129975

        Reviewed by Anders Carlsson.

        TextIterator refinements:
        - Use StringView instead of deprecatedCharacters to point to characters within strings.
        - Added TextIteratorCopyableText, a safe way to copy the current text of a TextIterator,
          for use by WordAwareIterator.
        - Removed m_shouldStop; iterators stop by setting m_positionNode to null, and there is no
          need for a separate boolean to do the same thing.
        - Got rid of all the boolean data members set based on the text iterator behavior; instead
          store the behavior in a data member and check it directly.
        - Changed most functions to use references rather than pointers.
        - Small micro-optimizations, such as using fastGetAttribute rather than getAttribute.
        - Switched to nullptr instead of 0 where appropriate.
        - Removed unused functions.
        - Cut down on use of abbreviations instead of words.
        - Renamed data members and argument names for clarity.
        - Split up assertions that needlessly asserted more than one thing in a single expression.
        - Treat CDATASection just like other Text, since its text will be visible.

        [CSS Regions] Scrolling regions with the mouse wheel only works properly if hovering over the region's padding

        Reviewed by Andrei Bucur.

        When searching for the region under the mouse pointer (to identify which region to scroll), 
        the localToAbsolute method must be called on the region container, not the region itself.
        Also, when calling the offsetFromContainer method on a named flow fragment,
        it must only take into consideration the border and padding of the fragment container,
        not its scrolled offset.

        iOS has a special FrameLoader::forceLayoutWithoutRecalculatingStyle()
        function that is called instead of FrameView::forceLayout(). This was unimplemented
        for the WK2 FrameLoaderClient, so no layout was forced, with the result
        that the contentSize was never updated and scrolling was broken.
        
        Fix by renaming the client function to forceLayoutOnRestoreFromPageCache()
        and having it return a bool to say whether the default forceLayout()
        should be done. WK1 can then continue to have its custom behavior,
        and Wk2 will simply do a forceLayout().

        Subpixel rendering: Simple compositing container layer (isSimpleContainerCompositingLayer) paints to wrong position.
        https://bugs.webkit.org/show_bug.cgi?id=129861

        Reviewed by Simon Fraser.

        This patch ensures that both the simple and non-simple cases paint to the same position.
        Simple compositing container layer codepath needs to take the fractional device pixel offset
        into account when painting. Without the fractional value, the final paint rounding could push the
        paint offset to a different position.
        retina example:
        compositing top-left: 0px 0px.
        fractional offset: 0.3px 0.3px
        painting coords without offseting: 0px 0px
                           with offseting: 0.5px 0.5px

        Traversal failure in a direct adjacent chain with tail backtracking lacks the path to clear the tail

        Reviewed by Gavin Barraclough.

        Direct adjacent backtracking use the stack to push the backtracking entry point and recover from there.
        In case of traversal failure, their is no point in recovering from the indirect adjancent entry point and
        we should clear entry point from the stack (which is the purpose of the tail).

        The adjancent tail was missing the part for clearing the stack in one case.

        The case with adjancent backtracking inside descendant backtracing was doing everything right. This patch
        generalize this code and the correct tail is fully generated by generateAdjacentBacktrackingTail().

        JumpToClearAdjacentDescendantTail becomes JumpToClearAdjacentTail, and this new backtracking state is added

        [Mac] Notify system malloc of fake memory pressure.
        <https://webkit.org/b/129908>

        After fixing the leak in r165252, I was surprised to find that it didn't
        show up on memory test bots. It turns out that while the memory is now
        getting freed, the system malloc implementation doesn't actually release
        pages back to the OS until there is memory pressure.

        Since we are just faking the memory pressure on bots, we have to let
        system malloc in on the fun, so we can get representative numbers.
        With this change, we should finally see the effect of not leaking the
        URLRequest object tree.

        Fixes an issue where an assertion failure would occur when visiting a web site whose on-disk
        app cache doesn't contain a manifest resource.

        For some reason an app cache for a web site may be partially written to disk. In particular, the
        app cache may only contain a CacheGroups entry. That is, the manifest resource and origin records
        may not be persisted to disk. From looking over the code, we're unclear how such a situation can occur
        and hence have been unable to create such an app cache. We were able to reproduce this issue using
        an app cache database file that was provided by a person that was affected by this issue.

        No test included because it's not straightforward to write a test for this change.

        outlineBoundsForRepaint() is expected to return the outline repaint rect. Using enclosingIntRect()

        Since enclosingIntRect() can return bigger rect than repaint rect, the old/new bounds' dimensions could end up

        appendChild shouldn't invalidate LiveNodeLists and HTMLCollections if they don't have valid caches
        https://bugs.webkit.org/show_bug.cgi?id=129727

        Reviewed by Andreas Kling.

        Before this patch, invalidateNodeListAndCollectionCachesInAncestors invalidated node lists and HTML
        collections on ancestors of a node whenever we're inserting or removing a child node. This patch
        makes HTMLCollections and LiveNodeLists register themselves with Document only when they have valid
        caches.

        Each user of CollectionIndexCache now implements willValidateIndexCache member function that gets
        called when CollectionIndexCache caches any state and necessitates the registration with document.

        * dom/ChildNodeList.h: Added an empty willValidateIndexCache since child node lists are never
        registered with document.

        * dom/CollectionIndexCache.h:
        (WebCore::CollectionIndexCache::hasValidCache): Added.
        (WebCore::CollectionIndexCache::nodeCount): Calls willValidateIndexCache when caching node count.
        (WebCore::CollectionIndexCache::nodeAfterCached): Ditto. Also assert that hasValidCache() true in
        the cases where we're simply updating our caches or adding more caches.
        (WebCore::CollectionIndexCache::nodeAt): Ditto. Also added a code to set the length cache when
        we've reached the end of the list. This should be a slight speed up on some cases.

        * dom/Document.cpp:
        (WebCore::Document::Document): Initializes a variable used by assertions.
        (WebCore::Document::unregisterNodeList): Added an early exit for when m_listsInvalidatedAtDocument
        is empty since invalidateNodeListAndCollectionCaches swaps out the list.
        (WebCore::Document::registerCollection): Removed the boolean hasIdNameMap since we now explicitly
        call collectionCachedIdNameMap in HTMLCollection.
        (WebCore::Document::unregisterCollection): Ditto. Exit early if m_collectionsInvalidatedAtDocument
        is empty since invalidateNodeListAndCollectionCaches swaps out the list.

        had already moved to the new document inside NodeListsNodeData::invalidateCaches.

        * dom/Node.cpp:
        (WebCore::Document::invalidateNodeListAndCollectionCaches): Swap the lists since invalidateCache
        tries to unregister node lists and HTML collections with document. Since this is the only case in

        and unregisterCollection, assert this condition via m_inInvalidateNodeListAndCollectionCaches.

        This regression started happening after we adopted the setPresentationValue

        it still thinks it is in presentation-value mode. Whenever the scrollbar grows, it 
        should be in non-presentation value mode.

        This causes the start playback button to be visible in the upper-left corner of the embed

        Space between double underlines does not scale with font size
        https://bugs.webkit.org/show_bug.cgi?id=129521

        Reviewed by Simon Fraser.

        This patch moves the logic about how far to draw the second underline (when text-decoration-style: double
        is specified) from InlineTextBox to GraphicsContext, because GraphicsContext is the authoritative source
        about how thick underlines should be. The space between the two underlines is set to the thickness of
        each of the underlines.

        This patch also deletes some unused code in InlineTextBox that was never getting triggered, in addition
        to unifying drawLineForText with drawLinesForText. This didn't have any performance impact in my testing.

        [CSS Regions] Overset computation is incorrect in some cases
        https://bugs.webkit.org/show_bug.cgi?id=129032

        Reviewed by Mihnea Ovidenie.

        This patch reworks the way overset is computed for regions and named flows.

        1. Regions overflow no longer trigger an overset changed event. This is because
        the overflow of a box is contained within the region range of the box. The content
        edge should be considered the logical bottom position of the content inside the
        flow thread.

        2. The regions events logic was moved from RenderFlowThread to RenderNamedFlowThread
        and from RenderRegion to RenderNamedFlowFragment (including the regionOverset property).

        3. The overset value of the named flow is no longer stored in the named flow. It is
        extracted from the overset of the last region in the chain.

        4. The regions overset is not computed every time the flow thread is laid out which
        should improve performance for flows with many regions. With the patch, each region
        computes the overset value during its layout when the flow thread is in the overflow
        or the final layout phase.

        5. The overset changed event is dispatched only at the end of the layout of the named flows,
        after all the region overset changes have been considered. This means that the overset
        event can't be dispatched in the middle of the auto-height processing algorithm that
        requires multiple layout passes for the flow threads.

        However, the region layout update event dispatch timing was not changed, it is dispatched
        every time the flow thread has a layout. This preserves the current behavior of the event.

        Tests: The old tests were modified to take into account the change.

        Web Replay: upstream input storage, capture/replay machinery, and inspector domain

        Reviewed by Timothy Hatcher, Joseph Pecoraro, and Andreas Kling.

        No new tests yet, as they rely on infrastructure tracked in https://webkit.org/b/129190.

        Replayable executions are organized into ReplaySessions, which can
        contain several ReplaySessionSegments that divide overall execution
        at main frame navigation boundaries. NondeterministicInput subclasses
        are stored in SegmentedInputStorage according to the input's InputQueue.

        Capture and playback are controlled at the page granularity by the Page's
        ReplayController. The controller knows how to create new segments, replay to
        arbitrary positions in the ReplaySession, and track the active InputCursor.

        The capturing and replaying input cursor subclasses encapsulate state for
        storing new inputs and loading/dispatching saved inputs, respectively.

        The ReplayAgent and associated inspector protocol domain is the friendly
        public API for programmatically capturing and replaying sessions.

        While generating GObject DOM API the generator should skip non pointer

        This will avoid the situation when Range.START_TO_START is defined as 0,

        The remaining attribute checkers appear to be less common than the simple value match.
        This patch adds them to SelectorCompiler for completeness but no attempt is made at optimizing them,
        they all default to function calls.

        If the assumption that those selectors are not common turn out to be incorrect, we should see
        the function calls in profiles and optimize them as needed.

        [iOS][WK2] Pages using tiled compositing layers allocate too many tiles on zoom
        https://bugs.webkit.org/show_bug.cgi?id=129471

        Reviewed by Simon Fraser.

        A few issues with TileController were causing sublayers of the root layers
        to tile incorrect surfaces on zoom.

        First, the exposedRect API was not updating the sublayers. The layers go correctly
        into tiling mode, but the tiles cover the full document instead of the visible area.

        The other major issue was the margins being applied to the coverage size in document
        coordinates. Since each margin is 512px, the total coverage size after zoom was
        gigantic.

        To solve this, this patch switch from the exposedRect API to the generic concept
        of VisibleExtentContentRect introduced for iOS WebKit1.

        a factor of 1.5.
        ViewUpdateDispatcher has all the information to compute a great tile coverage, I will need
        a follow up patch to fix that.

        Split UserActivity, simplify PageThrottler
        https://bugs.webkit.org/show_bug.cgi?id=129551

        Reviewed by Darin Adler.

        The class UserActivity currently implements two things – a hysteresis mechanism, and
        an abstraction of NSActivity controlled by that mechanism. PageThrottler implements
        its own hysteresis mechanism, which directly controls DOM timer throttling and also
        controls a couple of UserActivities, giving a total of 3 separate hysteresis mechanisms,
        layered two deep.

        Split UserActivity into three, with HysteresisActivity implementing an abstract hysteresis
        mechanism, UserActivity::Impl controlling the NSActivity, and then UserActivity combining
        these two back together. The interface to UserActivity is unchanged.

        Remove PageThrottler's bespoke hysteresis, replacing it with a use of HysteresisActivity.

            This patch fixes a crash in SMIL animations when keySplines are not

            "If there are any errors in the keyTimes specification (bad values,
            too many or too few values), the animation will have no effect."

            This patch simply checks that keyTimes is not empty. Previously,
            splinesCount was set to be m_keySplines.size() + 1 in
            SVGAnimationElement.cpp; this patch changes splinesCount to be equal

        Optimized querySelector(All) when selector contains #id

        Test: fast/selectors/querySelector-id-filtering.html

        The idea of this patch is to perform querySelector on a subtree
        rooted at the last element with #id matching. For example, if we have the selector
        "#foobar div a", we start by looking for the element with ID foobar in the TreeScope
        cache, and start matching the children from there.

        The idea comes from Rune for

        Filters should test for area instead of single dimension

        Reviewed by Dirk Schulze.

        A filtered SVG element with a sigle dimension bigger than 5000
        (counting the margin/border) will fail to render. So an element
        with 4000x4000 will render fine, while another with 5000x10
        won't. This patch instead tests against the total element area,
        which fixes such cases.

        It also fixes some layer violations where FilterEffectRenderer and
        RenderSVGResourceFilter were directly accessing the maximum filter
        size in FilterEffect. Since before a somewhat bigger filter would
        be aborted, it required to change the maximum kernel size
        for blur filter (some filters are slower to run than others for
        bigger SVGs).

        [CSS Grid Layout] Fix positioning grid items using named grid lines/areas
        https://bugs.webkit.org/show_bug.cgi?id=129372

        Reviewed by Darin Adler.

        Our code was assuming that a <custom-ident> in
        -webkit-grid-{column|row}-{start|end} and
        -webkit-grid-{column|row} was always a grid area name. That's
        wrong because the <custom-ident> could be also a explicitly named
        grid line or the an implicitly named grid line created by a grid
        area definition.

        The style resolution code was not correct either. This patch fixes
        it so it now matches the spec, which means that:
        - first we try to match any existing grid area.
        - then if there is a named grid line with the name
        <custom-ident>-{start|end} for -webkit-grid-{column|row}-{start|end}
        defined before the grid area then we use it instead of the grid
        area.
        - otherwise if there is a named grid line we resolve to the first such line.
        - otherwise we treat it as 'auto'.

        Fixing this uncovered a bug in GridPosition, we were not using the
        name of the stored grid area to check if two GridPositions were
        the same.

        [CSS Shapes] Update line segments for ShapeInside only if the new line is wide enough

        Shape-inside can make a line only narrower than the original line width, thus we don't need
        to update the line/shape segments in fitBelowFloats for every single line inside shape-inside.
        This patch adds a helper function, which updates the line segments, furthermore it updates the

        In the css3-text spec (http://www.w3.org/TR/css3-text/#bidi-linebox):

        The start and end edges of a line box are determined by the inline
        base direction of the line box. In most cases, this is given by
        its containing block's computed ‘direction’. However if its
        containing block has ‘unicode-bidi: plaintext’, the inline base

        the bidi paragraph to which it belongs: that is, the bidi
        paragraph for which the line box holds content.

        This patch just implements the behavior described above modifying

        JSC ignores the extra memory cost of HTMLCollection after a major GC

        Reviewed by Andreas Kling.

        Report the extra memory cost of HTMLCollection to JSC.

        Unfortunately, the existing mechanism to report the extra memory cost in toJS is insufficient for
        HTMLCollection since collection caches are populated later when HTMLCollection is accessed. Also,
        the extra memory cost reported by Heap::reportExtraMemoryCost will be thrown away after a major GC.

        To work around this limitation, added a visitor.reportExtraMemoryUsage call inside visitChildren
        for interfaces with a newly added ReportExtraMemoryCost IDL extension flag to report the extra cost.

        Since we may need to generate visitChildren when this flag is set, we can't automatically detect
        and generate calls using C++ template as done in r148648.

        Reviewed by Geoffrey Garen.

        Add support for compiling value matching when matching attributes in Selector.
        This patch only adds exact matching, the other cases will follow.

        There is a little infrastructure changes since FunctionCall now needs to support
        calls taking 2 arguments. The fun begins when the arguments are not in the right
        registers and need to be moved to the right place. Otherwise the code is straightforward.

        In SelectorCompiler, it is necessary to handle two different cases of matching: case sensitive
        and case insensitive. The choice is done in part at compilation time by asking HTMLDocument
        if the name filter can include case insensitive attribute. The other part is done at runtime
        by querying the element for its type and document.

        Here we need to swap two registers, but we cannot allocate a new register (because the context
        of the function call may have taken all the available registers already).

        On x86, the solution is simple, we can swap the two registers without side effects.

        On other platforms, it is a little more complex. If there is any available register, we can just
        use it as a temporary to make the swap.
        If there are no available registers, we know that all the registers are taken. Since swapArguments()
        was called after pushing all the arguments on the stack, we can safely trash the value of any of those.
        We take the first available register that is not a function argument and use it as a temporary.

        (WebCore::FunctionCall::prepareAndCall):
        This is the fun part, we have two registers where the values must go before the function call. The values
        can be in any combination of the allocated registers. The code here needs to move the two values to
        their target register while avoiding conflicts.

        The matching code is moved in a local scope. This is done to recover the register of qualifiedNameImpl
        before doing any value matching. That register can then be used to store the expected value when matching
        an attribute value.
        It is unfortunate there is so much register pressure in this part.

        Value matching is done outside the loop. The idea is to keep the loop really small since in the vast majority
        of cases, name matching fails.
        If the value matching fails, we jump back into the tight loop.

        This is not ideal in all situation. For example trivial name matching with trivial value matching should
        be done in loop. There is a FIXME to improve those cases later.

        In the case sensitive branch, things are really simple. We have to AtomicStringImpl pointers, if they
        don't match, it is a failure.

        The case sensitive branch start by comparing the pointers in case the values are equal. This is a common
        case and it simplifies the cases for SVG, XHTML, etc.
        If the two values are not equal, we must first find if the context requires case insensitive comparison
        (HTMLElement in HTMLDocument). If the conditions require case insensitive matching, we then fall back
        to a function call.

        When drawing glyphs in an SVG font, the glyphs are converted to paths and then filled. This patch moves
        the glyph -> path conversion into a helper class, GlyphToPathTranslator, and creates an implementation
        for the SVG drawing code. Once this helper class is created, it can be used to trace paths in order
        to make underlines skip over SVG glyphs. This helper class also has an implementation for non-SVG glyphs,
        which allows for the glyph tracing code to be paramaterized over the implementation of the helper class
        rather than if the FontData itself is SVG or not.

        Indenting an indented image element resulted in an extra indentation
        https://bugs.webkit.org/show_bug.cgi?id=129201

        Reviewed by Enrica Casucci.

        The bug was caused by endOfParagraph returning a position at the beginning of a block when the position
        passed into the function was at the beginning of the block. Consider the following DOM:
        <blockquote><img></blockquote>

        When endOfParagraph is called on (blockquote, 0), the condition r->isBR() || isBlock(n) in endOfParagraph
        matches immediately on startNode and it returns (blockquote, 0) again.

        This resulted in moveParagraphWithClones invoked by indentIntoBlockquote to erroneously clone the inner
        blockquote. Worked around this bug in ApplyBlockElementCommand::formatSelection by checking this specific
        condition and moving the position to the end of the block. Unfortunately, a lot of existing code depends
        on the current behavior of endOfParagraph so fixing the function itself was not possible.

        There was another bug in indentIntoBlockquote to incorrectly insert a new blockquote into the existing
        blockquote due to the code introduced in r99594 to avoid inserting before the root editable element.
        Since this happens only if outerBlock is the root editable element, which is nodeToSplitTo or an ancestor
        of nodeToSplitTo, explicitly look for this condition.

        Reviewed by Dan Bernstein.

        Add iOS support for navigator.onLine and online/offline events. Since
        it can be expensive to query CPNetworkObserver, wait to do so until
        someone calls NetworkStateObserver::onLine() or
        NetworkStateObserver::addNetworkStateChangeListener(). For clients that
        don't wish to observe network reachability at all, add a global opt-out.
        These clients will only pay the cost of CPNetworkObserver if they load
        a page that explicitly accesses navigator.onLine.

        Web Replay: route through UserInputBridge when delivering user inputs to WebCore
        https://bugs.webkit.org/show_bug.cgi?id=128150

        Reviewed by Timothy Hatcher.

        Add an UserInputBridge instance to each Page. WebKit2 routes a page's user inputs through
        the WebCore page's user input bridge so that the inputs can be selectively captured, filtered,
        and replayed using instrumentation inside the UserInputBridge.

        For now, the routing methods of UserInputBridge have no replay-specific code paths, and just
        put the input delivery code inside WebCore rather than its external clients. Replay-specific
        code paths will be added once https://bugs.webkit.org/show_bug.cgi?id=128782 is fixed. However,
        once complete the code will work as follows:

        - When neither capturing or replaying, behavior is unchanged.

        - When capturing user inputs, each external input is saved into a replay log as it crosses
        the bridge from outside WebCore.

        - When replaying, the bridge closes and user inputs from WebKit2 are not accepted. Instead,
        the saved inputs from the replay log are re-dispatched as if they had crossed the bridge.

        (WebCore::Document::topDocument): Fall back to pre-r162947 way of determining the top document

        In the first case, the determined top document is actually the document currently loaded in the
        Frame to which the cached document is still connected, which is obviously not desired. In the
        second case the top document is similarly incorrectly deduced, leading to non-deletion of the
        proper top document's AXObjectCache. Because of this AccessibilityRenderObjects are not detached
        which results in assertions in RenderObject destructor where the objects are found to be still

        Avoid unnecessary HTML Collection invalidations for id and name attribute changes
        https://bugs.webkit.org/show_bug.cgi?id=129361

        Reviewed by Benjamin Poulain.

        Before this patch, setting id and name attributes resulted in traversing all the ancestors to invalidate
        HTML collections on those nodes whenever we had more than one HTMLCollection alive.

        Avoid the traversal when HTMLCollections don't have any valid id and name map caches by making each
        HTMLCollection explicitly call collectionCachedIdNameMap and collectionWillClearIdNameMap when it caches
        or clears the id and name map.

        Inspired by https://chromium.googlesource.com/chromium/blink/+/5b06b91b79098f7d42e480f85be32198315d2440

        https://bugs.webkit.org/show_bug.cgi?id=129259

        Reviewed by Simon Fraser.

        Border edges are painted as (semi)independent rectangles. When snapping an edge rectangle
        to device pixels, its painted dimensions depend on its size and its fractional position.
        Specific combination of position and border width can result in painting edges sized differently.
        Using device snapped border width to calculate inner/outer rectangles helps to maintain
        uniform border width.

        Add a DefaultVisitedLinkProvider and route visited link actions through it
        https://bugs.webkit.org/show_bug.cgi?id=129285

        Reviewed by Dan Bernstein.

        DefaultVisitedLinkProvider currently just forwards everything to the visited link strategy,
        but will soon take over the responsibilities of visited link handling from PageGroup.

        [CSS Grid Layout] handle undefined RemainingSpace in computeUsedBreadthOfGridTracks algorithm
        https://bugs.webkit.org/show_bug.cgi?id=128372

        Reviewed by David Hyatt.

        From Blink r165692 by <svillar@igalia.com>

        The spec defines a different code path for the computeUsedBreadthOfGridTracks algorithm
        http://dev.w3.org/csswg/css-grid/#function-ComputeUsedBreadthOfGridTracks.

        Basically the track breadth is different when the available size is undefined and thus,
        cannot be taken into account during the computations.
        The available size is undefined whenever the height is auto or the grid element has a
        shrink-to-fit behavior.

        It was also renamed the function to match the specs so the function name starts with
        'compute' instead of 'computed'.

        No new tests, but added new cases to some of them.

        Reviewed by Antti Koivisto.

        The painting of the region's layer should not be aborted so early if the region's fragment shouldn't be painted
        because that would prevent all the layer's children from being painted.

        Another problem this patch addresses is that clipping should also be performed when the clip rect is empty,
        which is what happens when painting in a tile in which the flowed element would normally be painted
        if it wasn't clipped by the region.

        Adding a clear:both to the end of content.

        I can't handle the case of the cursor appearing above the bottom of
        absolutely positioned divs (of the case of floats inside absolutely
        positioned divs) because you can't know where the bottom of a div
        will end up being rendered (it is affected by things like browser
        window width and text size settings). Therefore, the only case I
        can handle is the case where there is a floating div in the same

        jsDocumentPrototypeFunctionGetElementById should not create an AtomicString for the function argument
        https://bugs.webkit.org/show_bug.cgi?id=128893

        Reviewed by Darin Adler.

        The declaration of TreeScope::getElementById() was taking an AtomicString as the parameter.
        Because of this, all the call sites manipulating String were creating and keeping alive an AtomicString
        to make the call.

        This had two negative consequences:
        -The call sites were ref-ing the ID's atomic string for no reason.
        -When there is no ID associated with the input string, an atomic string was created for the sole
         purpose of failing the query. Since IDs are stored as AtomicString, if there is not an existing
         AtomicString for the input, there is no reason to query anything.

        'mouseenter' mouse compat event not fired when listeners for touch events
        https://bugs.webkit.org/show_bug.cgi?id=128534

        Reviewed by Andreas Kling.

        The code dispatching mouseenter and mouseleave events was making the assumption that
        only mouse move would cause Document::updateHoverActiveState.

        This is not true in some cases. In the case of this bug, the first touch handler sets
        the hover state. From there, the code handling enter/leave is in an inconsistent state.

        This patch changes the delivery of mouse enter/leave events to be done through the regular
        processing of mouse events. The update is done with the mouseover and mouseout events.

        [CSS Regions] Regions don't paint correctly in new-multicol elements
        https://bugs.webkit.org/show_bug.cgi?id=120711

        Reviewed by David Hyatt.

        This patch implements basic support for regions inside multi-column elements.
        Currently, the painting and hit-testing logic of CSS Regions is not aware of
        enclosing multi-column elements. The change is integrated at a layer level by
        making use of the pre-computed layer fragments during the painting and hit-testing
        phases for regions.

        There are limitations such that self painting layers found inside the named flow
        thread layer will not be correctly processed because they don't go through the
        layer fragment collection step. This is not trivial to implement because the enclosing
        pagination layer provided by the multi-column element is not visibile from inside
        the named flow thread layer and they reside in different coordinate systems.

        A side effect of this patch is the fix of regions incorrect clipping in certain
        cases (when both a region and its container clip their overflow, the region's
        content is visible outside the container).

        m_ancestorDisabledState should never be unknown

        Reviewed by Benjamin Poulain.

        In order to resolve the bug 129035, a text form control elements needs to synchronously change
        its inner text element's editability by setting or unsetting contenteditable content attribute.
        Before this patch, we could not do this because editability of a text form control dependent on
        its disabled-ness which was only computed lazily via updateAncestorDisabledState().

        This patch makes HTMLFieldSetElement and HTMLFormControlElement update this state synchronously.
        To avoid O(k) DOM traversal, where k is the depth of the tree, in insertedInto and removedFrom of
        HTMLFormControlElement on most pages, a new document-level flag, m_disabledFieldsetElementsCount,
        has been added to indicate whether the document contains any disabled fieldset or not.

        Also renamed the misleadingly named disabledAttributeChanged to disabledStateChanged, and added
        new function of the same name (disabledAttributeChanged) to be used by HTMLFieldSetElement
        for keeping the document-level flag up-to-date upon disabled attribute changes.

        Stop generating Objective-C bindings for the SVG DOM
        <http://webkit.org/b/129107>

        Reviewed by Timothy Hatcher.

        Bug 114076 stopped compiling the Objective-C bindings for the
        SVG DOM, but we continued to generate the header and source
        files after that landed in r147822.  This patch also stops
        generating the unused header and source files.

        * DerivedSources.make:
        - Split BINDING_IDLS into NON_SVG_BINDING_IDLS and
          SVG_BINDING_IDLS so that they may operated on separately.
        - Define BINDING_IDLS again as the full list of IDL files.
        - Rename DOM_CLASSES to JS_DOM_CLASSES so that JavaScript
          bindings are still generated for all IDL files.
        - Add OBJC_DOM_CLASSES so that Objective-C bindings are only
          generated for non-SVG IDL files.
