        SVGFilterBuilder should drive the builtin sourceAlpha from the passed sourceGraphic
        https://bugs.webkit.org/show_bug.cgi?id=144137

        Reviewed by Darin Adler.

        The SourceAlpha should be driven from the last applied FilterEffect. This
        will require the SourceAlpha FilterEffect to wrap a FilterEffect rather
        than just getting the SourceGraphic reference from FilterEffectRenderer.

        This is based on the Blink patch:
        https://src.chromium.org/viewvc/blink?revision=194115&view=revision.

        REGRESSION (r174283): disabled default buttons use impossible-to-read white text on Mac

        Reviewed by Simon Fraser.

        No test because DumpRenderTree and WebKitTestRunner don't have a good method
        for testing behaviors that are specific to active windows. That's the same reason
        that the change that caused this bug didn't come with a regression test.

        (WebCore::RenderTheme::adjustStyle): Renamed "e" to "element". Added a comment to
        clarify the meaning of the setInsideDefaultButton function, and added an

        REGRESSION (r176751): line-height ignored in <button> elements
        https://bugs.webkit.org/show_bug.cgi?id=144234

        Reviewed by Antti Koivisto.

        Test: fast/forms/button-line-height.html

        The theme code was overriding line heights on all themed form controls.
        Instead it should have only overridden line height when the theme overrides the font.
        For <input type=button> on Mac, the theme always overrides the font, but for
        other elements like <button> it does not.

        * platform/Theme.h: Changed controlFont to return an Optional so we can tell
        when the theme is overriding the font. Otherwise if the font from the user-agent
        style sheet and the font from the theme are the same, we will think we are not
        overriding the font when we actually are.

        * platform/mac/ThemeMac.h: Updated controlFont to return Optional.

        setFontDescription already does an "==" comparison; we don't have to do
        that twice.

        Expand compositing coverage rect when scrolling and animating
        https://bugs.webkit.org/show_bug.cgi?id=144214
        rdar://problem/20695926

        Reviewed by Darin Adler.
        
        r183300 added a secondary rect that gets mapped through graphics layers during
        layer flushing, which represents a rect, in layer coordinates, that represents
        the portion of this layer that's visible in the viewport.
        
        This patch extends that rect based on scrolling and animating, with the extended
        coverage rect being mapped into descendants (where it's used to determine whether
        they should detach their backing store). This required moving the responsibility for
        extending the coverage rect from TileController (where it was used to compute
        tiled extent), to GraphicsLayerCA. Thus, GraphicsLayerCA now owns the concept
        of coverage rect, and pushes it onto TileControllers.

        Test: compositing/tiling/transform-origin-tiled.html

        * platform/graphics/TiledBacking.h: Coverage rect is now pushed onto
        TiledBacking from outside; new functions reflect that.
        * platform/graphics/ca/GraphicsLayerCA.cpp:
        (WebCore::GraphicsLayerCA::flushCompositingStateForThisLayerOnly): No need to pass
        old visible rect to commitLayerChangesBeforeSublayers.
        (WebCore::accumulatesTransform):
        (WebCore::GraphicsLayerCA::recursiveVisibleRectChangeRequiresFlush): Now calls computeVisibleAndCoverageRect(),
        then adjustCoverageRect() which adjusts for scrolling and animations.
        (WebCore::GraphicsLayerCA::computeVisibleAndCoverageRect): Fetch the coverage rect from the
        TransformState, but we can only use this if mapping it through various transforms didn't clamp
        it (which can happen with severe rotations in perspective).
        (WebCore::GraphicsLayerCA::adjustCoverageRect): If this layer represents the page tiled backing,
        ask the TileController to do coverage adjustment (code which should move into here eventually).
        For other tiled layers, do motion-based adjustment. This should really be done for all layers
        (an animating non-tiled layer may contain a tiled layer).
        (WebCore::GraphicsLayerCA::setVisibleAndCoverageRects): The VisibleRectChanged wasn't needed
        any more; layers only react to changed in coverage rect now.
        (WebCore::GraphicsLayerCA::recursiveCommitChanges): If adjustCoverageRect() changed the
        coverage rect, here we push the new rect back into the TransformState so it will affect
        descendants.
        (WebCore::GraphicsLayerCA::commitLayerChangesBeforeSublayers):

        (WebCore::TileController::bounds):

        Track a coverage rect through GraphicsLayerCA flushes, use it to mark backing store attached

        Push in the clipRect as the secondary rect when doing a GraphicsLayerCA flush,
        which maps this rect through all the layers. Each layer tests intersection with
        this rect to determine if its backing store should be attached.
        
        This will cause us to drop backing store for layers that don't intersect the
        visible part of the view, which is too aggressive. A future patch will add
        some padding.

        [iOS] Reimplement r182512 and r183153 in a cleaner way
        https://bugs.webkit.org/show_bug.cgi?id=144151

        Reviewed by Enrica Casucci.

        On iOS, we create FontPlatformData's ctFont() by round tripping it through a CGFontRef.
        This causes the resultant ctFont() to lose system-font-ness. Patches r182512 and r183153
        react to this fact by making users of a FontPlatformData use the original font passed in
        to the FontPlatformData instead of the FontPlatformData's ctFont(), but only if we
        detect that the FontPlatformData represents a system font (the underlying APIs have
        different behavior for system fonts and non-system-fonts).

        However, on OS X, we create a FontPlatformData's ctFont() directly from the original
        font passed in to the constructor. This preserves system-font-ness (because it no
        longer has the CGFontRef in the middle of the transformation). Therefore, OS X has the
        correct behavior regarding system fonts.

        The difference between the two ctFont() creation codepaths seems to be historical
        rather than intentional. Rather than change all the call sites of ctFont() to use a
        different platform font object if a system font is detected, a cleaner solution is to
        simply unify the two ctFont() creation codepaths to the version which preserves system-
        font-ness. Doing this will make all users of FontPlatformData automatically have the
        correct behavior with no updates.

        This patch reverts the relevant parts of r182512 and r183153 in favor of this new
        solution.

        No new tests because there is no behavior change.

        [Cocoa] Start cleaning up FontPlatformData
        https://bugs.webkit.org/show_bug.cgi?id=144133

        Reviewed by Enrica Casucci.

        This is the start of a crusade to ultimately remove one of the CTFontRefs which we have inside
        FontPlatformData. This patch starts this effort out by removing the FontPlatformData
        constructor which accepts an NSFont. This constructor simply casts the NSFont to a CTFontRef,
        and forwards to another constructor. This patch moves this cast to callers of this constructor,
        thereby enumerating the places we have left that use NSFont with FontPlatformData.

        This patch also cleans up two of the constructors in FontPlatformData.cpp to forward on to
        a common constructor.

        This patch also collects places inside FontPlatformDataCocoa.mm where we check if a pointer is
        not 0 and not -1, and puts this common code inside a new function,
        FontPlatformData::isValidCTFontRef().

        Memory cache live resources repeatedly purged during painting
        https://bugs.webkit.org/show_bug.cgi?id=144104
        <rdar://problem/20667695>

        Reviewed by Chris Dumez.

        On some PLT pages (like nytimes.com) we get into state where painting repeatedly purges live bitmaps.
        This slows down page loads significantly.

        This might have regressed because improvements in page caching keep more pages and so resources 'live'.

        With this path we do all regular cache pruning asynchronously. If memory is really critical
        the low memory handling code will still prune synchronously.

        CrashTracer: WebProcess at com.apple.WebCore: WebCore::toScriptElementIfPossible + 4
        https://bugs.webkit.org/show_bug.cgi?id=144050

        Reviewed by Chris Dumez.

        We are seeing null Element pointer crashes with this stack:

        47 com.apple.WebCore:  WebCore::toScriptElementIfPossible + 4 <==
        47 com.apple.WebCore:  WebCore::ScriptRunner::timerFired + 452
        47 com.apple.WebCore:  WebCore::ThreadTimers::sharedTimerFiredInternal + 175

        The most likely cause seems to be that this code

            ASSERT(m_pendingAsyncScripts.contains(scriptElement));
            m_scriptsToExecuteSoon.append(m_pendingAsyncScripts.take(scriptElement));

        in ScriptRunner::notifyScriptReady fails to find scriptElement and we are left with null entry in
        m_scriptsToExecuteSoon. However I haven't managed to repro this or find the exact path how this
        could happen. The related code is fragile with lot of state (especially in ScriptElement class)
        and involves many opportunities for re-entry via scripts.

        No repro, no test case.

        * dom/ScriptRunner.cpp:
        (WebCore::ScriptRunner::timerFired):

            Paper this over by adding a null check. We could check m_pendingAsyncScripts.take() above
            but this also covers possibility this is caused by something else.

        [iOS] Add a wrapper around the hosted AVPlayerLayer to intercept -setBounds:
        https://bugs.webkit.org/show_bug.cgi?id=144129

        Reviewed by Simon Fraser.

        When passing the hosted AVPlayerLayer to the fullscreen controller, the new superlayer will
        resize the hosted layer with a call to -setBounds:. But because this is a hosted layer, the
        bonuds change has no effect. Instead, wrap the CALayerHost in another CALayer whose job it is
        to intercept -setBounds: in the same way that WebAVVideoLayer did. In fact, we should just use
        that wrapper class inside WebAVVideoLayer as well, to avoid duplicating code.

        Drive-by Fix: Null-check m_videoElement in setVideoLayerFrame().

        On some PLT pages (like nytimes.com) we get into state where painting repeatedly purges live bitmaps.
        This slows down page loads significantly.

        This might have regressed because improvements in page caching keep more pages and so resources 'live'.

        With this path we do all regular cache pruning asynchronously. If memory is really critical

        WebDiagnosticLoggingClient is leaking. It is constructed inside WebPage
        constructor but there is no code destroying it.

        This patch adds a new xxxDestroyed() virtual function to
        DiagnosticLoggingClient and that is overriden in
        WebDiagnosticLoggingClient to call "delete this". This is the same
        pattern as for other WK2 clients (e.g. WebFrameLoaderClient,

        The most likely cause seems to be that this code

            ASSERT(m_pendingAsyncScripts.contains(scriptElement));
            m_scriptsToExecuteSoon.append(m_pendingAsyncScripts.take(scriptElement));

        in ScriptRunner::notifyScriptReady fails to find scriptElement and we are left with a null entry in
        m_scriptsToExecuteSoon. However I haven't managed to repro this or find the exact path how this
        could happen. The related code is fragile with lot of state (in ScriptElement class)
        and involves many opportunities for re-entry via scripts.

        No repro, no test case.

        [iOS] Move computeCoverageRect code from FrameView into TileController
        https://bugs.webkit.org/show_bug.cgi?id=144087

        Reviewed by Benjamin Poulain.
        
        There is code in four different places that adjusts tiling coverage rect:
        1. LegacyTileCache. This will remain unchanged.
        2. FrameView::computeTileCoverageRect(). This was added to do velocity-based
        page tiled coverage expansion for iOS WK2.
        3. TileController::computeTileCoverageRect(): this is used for the page tiles
        on Mac.
        4. GraphicsLayerCA::adjustTiledLayerVisibleRect(). This is used by non-page
        tiled layers on both iOS and Mac.
        
        This patch reduced this list to 3, coalescing FrameView::computeTileCoverageRect()
        and TileController::computeTileCoverageRect(). It removes the rect inflation that
        affects the visibleRect passed into rootLayer->flushCompositingState() for iOS,
        but the page tiles now do an identical coverage inflation. The visible rect
        change does affect visible rect computations for non-page tiled backings, but
        a future patch will restore that.

        Add new optimized fullscreen delegate methods
        https://bugs.webkit.org/show_bug.cgi?id=144071

        Reviewed by Eric Carlson.

        AVPlayerViewController requires three new delegate methods to be implemented by WebKit which
        notify the delegates exactly when the owning view will enter and leave fullscreen mode. One
        of the delegate methods (-enterOptimizedFullScreenModeRedirectingVideoToLayer:) gives the
        delegate an opportunity to move the video sublayer into a new CALayer. The matching delegate
        (-leaveOptimizedFullScreenMode), allows us to return our sublayer back to its original parent.
        The third delegate (-isOptimizedFullscreenPossible) is required so the AVPlayerViewController
        knows whether to allow a standard -> optimized fullscreen transition.

        Drive-by fix: initialize ivars at declaration time.

        Reviewed by Enrica Casucci.

        Determining caret locations often uses the complex text codepath, which means
        the complex text codepath must know about custom tracking.

        This regression is due to r182512.

        Note that this patch is a short-term solution until I can solve the bigger issue of
        having two CTFontRefs and using each in their proper place.

        This new interface is not exposed to JS scripts as specified, using NoInterfaceObject.

        A controller is created at the time a ReadableJSStream is started and it is owned by it.
        The controller may outlive the stream but as its reference will be reset, the calls to
        its methods would result in exceptions.

        The constructor is not implemented yet.

        This patch is renaming these LayoutBox methods, because of their names
        don't match with the getters and setters, which is confusing. Specially
        now that we also have hasOverrideContainingBlockLogical{Height,Width}().

        No new tests (this is just a refactoring).

        [Mac][MediaSource] Crash when SourceBuffer::provideMediaData() is called re-entrantly.
        https://bugs.webkit.org/show_bug.cgi?id=144023

        Reviewed by Eric Carlson.

        Fixes non-deterministic crash in media/media-source/media-source-stalled-holds-sleep-assertion.html.

        Platform changes have introduced a re-entrancy to provideMediaData().  Calling
        SourceBufferPrivate::enqueueSample() can result in a re-entrant call back into
        SourceBuffer::provideMediaData(). To protect against this, wrap the client call
        from SourceBufferPrivateAVFObjC::didBecomeReadyForMoreSamples() to
        SourceBuffer::sourceBufferPrivateDidBecomeReadyForMoreSamples() in a dispatch_async() to the
        main thread. This gives the original provideMediaData() a chance to finish before the next
        one begins.

        Use ASSERT_WITH_SECURITY_IMPLICATION() for NoEventDispatchAssertion as
        firing JS events can cause arbitrary JS execution which often leads to
        security bugs when event firing is forbidden. For e.g. firing events
        from ActiveDOMObject::suspend() means JS can construct or destroy
        ActiveDOMObjects while we are iterating over them.

        r177494 regressed loading of data URIs in masks with remote content, triggering
        a cross-domain error which occurs because the mask loading happened via a separate
        SVGDocument.
        
        Fix by checking for data URIs at parsing time, which is what we used to do.

        Crash when showing Web Inspector on page with 'multipart/x-mixed-replace' main resource
        https://bugs.webkit.org/show_bug.cgi?id=143979
        <rdar://problem/20594948>

        Reviewed by Timothy Hatcher.

        InspectorDOMAgent::m_document was updated only once per load, from
        FrameLoader::dispatchDidCommitLoad(). However, dispatchDidCommitLoad()
        is not called for follow-up multipart replacing loads. You can see this
        from the following check in DocumentLoader::commitData():
            if (!isMultipartReplacingLoad())
                frameLoader()->receivedFirstData();

        As a result, in the case of a 'multipart/x-mixed-replace' main resource
        InspectorDOMAgent::m_document would quickly get outdated as we create
        a new Document for each replacing load. This would lead to Web Inspector
        code using a Document without frame and causing crashes.

        This patch calls InspectorInstrumentation::frameDocumentUpdated() from
        Frame::setDocument() so that InspectorDOMAgent::m_document is always up
        to date.

        No new tests, not easily testable as the main resource needs to be
        'multipart/x-mixed-replace'.

        (WebCore::Document::applyXSLTransform):

        After r181656, all requestAnimationFrame was falling back to timers, and not

        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().

        When we compute huge values for line-height through percentage or CSS
        calc, we'll overflow the integer and later on
        ShapeOutsideInfo::computeDeltasForContainingBlockLine will ASSERT
        because it expects non-negative line height.  So for the computed
        line-height, clamp to an integer range to avoid overflow. Note that
        the code path for percentages here is safe because LayoutUnit clamps
        to an int on conversion.

        Use less memory when compiling content extensions
        https://bugs.webkit.org/show_bug.cgi?id=143857

        Reviewed by Benjamin Poulain.

        When compiling a content extension, we convert the rule list into several intermediate forms:

        1) A String.
        2) A JSValue from JSONParse in loadEncodedRules.
        3) A Vector of ContentExtensionRules.
        4) A CombinedURLFilters object representing the pieces of the regular expressions from the triggers.
        5) A Vector of NFAs.
        6) A DFA for each NFA.
        7) A Vector of DFABytecode.
        
        Each one of these contains all the information contained in the content extension,
        so we do not need to keep them all in memory at the same time like we are doing now.
        When we are done with one, we can free that memory to greatly reduce the maximum memory usage while compiling.
        The next step will be to reduce the copies of the original JSON String and to generate NFAs one at a time.

        Regression(r182517): WebSocket::suspend() causes error event to be fired
        https://bugs.webkit.org/show_bug.cgi?id=143806
        <rdar://problem/20559812>

        Reviewed by Alexey Proskuryakov.

        WebSocket::suspend() causes an error event to be fired after r182517.
        This is not allowed as firing the event could trigger arbitrary JS
        execution, which is no longer allowed at this point.

        This patch delays the error event firing until after
        WebSocket::resume() is called, similarly to what we already do for
        the close event.

        Also add assertions in WebSocket::suspend() / WebSocket::resume()
        that will be hit if JS events are fired from within these functions.
        The pre-existing closed-when-entering-page-cache.html test is hitting
        one of these assertions without the fix above.

        Minimum font size pref breaks SVG text very badly.
        https://bugs.webkit.org/show_bug.cgi?id=143590.

        Reviewed by Simon Fraser.

        When enabling the minimum font size perf, the computed font size is set
        to the minimum font size if the computed value is smaller than the minimum.
        The bug happens because the SVG text element applies its scaling on the
        computed value after applying the minimum font size rule. This means the
        final computed value for the font size will be the scaling of the minimum
        font size and not minimum font size itself. What we need is to postpone
        applying the minimum font size rules, till the SVG scaling is applied.

        After r180020, we are stricter and no longer accept CSS resources that

        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.

        textPath layout performance improvement.
        https://bugs.webkit.org/show_bug.cgi?id=141570.

        Reviewed by Darin Adler.

        The bottleneck of the text-on-path performance is the position and angle
        calculations for every single character. If the number of characters is
        'n' and the number of path elements is 'm', the total number of processing
        the path elements is O(2 x n x m). What makes it really worse is, for every
        curve we keep splitting the curve till the split curve is almost a straight
        line. The changes we need to do are:
        1. Merge the position and the angle traversals in one pass since they are
           returning info for the same length on the path. There is a degenerate
           case for the starting point when calculating the angle. The original
           code was solving this problem by passing an epsilon instead of zero but
           because traversing the path for position and angle are now merged, we
           will pass zero for the starting point as is. All we need is to move one
           step ahead without moving the position. We need the extra step forward
           to calculate the slope of the path at the starting point.
        2. We need to add a new mode to traversing a path. The new mode will take
           a vector of lengths and returns a vector of arrow vectors. Every arrow
           vector represents a position and an angle on the path at a certain length.
           This requires changing the SVGTextLayoutEngine to calculate the lengths
           of the characters on the curve first and then passing all of them to the
           path traversal function. Instead of traversing the path for every length,
           we are going to get the required point and angle from the vector of arrow
           vectors.

        This patch is addressing the first fix only. The second one will require
        refactoring the SVGTextLayoutEngine so I am going to address it in a
        different patch.

        Add a conservative DFA minimizer for the content extension matcher
        https://bugs.webkit.org/show_bug.cgi?id=143501

        Reviewed by Alex Christensen.

        This patch adds a simple minimizer for DFA graphs. It is not a perfect minimizer:
        some indistinguishable are not merged, but no two distinguishable are merged.

        The general idea of the algorithm is to put all the state into a single set
        and partition iteratively until it is impossible to split any subset by using
        a transition to distinguish two states.

        Let's ignore fallback transition for now, and I'll explain later how they fit in
        the big picture.


        The first thing we do is create a partition of the transition by grouping every
        transition by the same character in the same subset. This partition of transitions
        is the base by which we will partition the states.

        Each subset in the transition partition is a "distinguisher" by which we can
        separate the state partition.

        We also create a second partition, the state partition. This is where we keep
        all the subsets of states that have been split so far.

        Let say we have the following graph.

            1 --a--> 2
            1 --b--> 3
            2 --c--> 4 (final)
            3 --c--> 4 (final)

        The partition of transition would start with:
        Set 0:
            1 --a--> 2
        Set 1:
            1 --b--> 3
        Set 2:
            2 --c--> 4
            3 --c--> 4

        The state partition would have a single set with { 1, 2, 3, 4 }.


        Next, we split the state partition by distinguishable final states. In this case,
        we would split it into { 1, 2, 3 }, { 4 }.

        We then refine the transition partition by splitting it by the states that have
        been distinguished. Here, the only transitions to 4 are both is the same set (set 2),
        so the transition partition remains the same.


        We can now execute the main loop of the algorithm:
        1) Split the states by the transitions.
        2) Split the transitions that are now reaching two different sets of the state partition.
        3) Add any newly discovered "distinguisher" (the ones we split) to the list of "distinguisher"
           to process.

        In this case, we just iterate over the partition set in order, and add newly split transitions
        to the end of the list.

        In the example, we would first visit set 0. We have that state 1 is distinguishable
        by "a", and the state partition would become { 1 }, { 2, 3 }, { 4 }.

        We then visit transition set 1, it distinguishes state 1 which is already alone -> nothing to do.

        Finally, we process the transition set 2, it distinguishes 2 and 3, they are already in the same
        set -> nothing to do.

        There is no more transition to process, we have 3 unique subsets and we should merge 2 and 3.

        ---

        Okay, now how to we fit fallback transition in this model. In this patch, I take the conservative
        approach: we split everything assuming fallback transition do not exist, then we refine
        by the fallback transitions.

        Let's take the following example:
            1 --a--> 3
            2 --a--> 3
            1 -[f]-> 4
            2 -[f]-> 5

        and at this stage in the algorithm, we have the sets { 1, 2 }, { 3 }, { 4 }, { 5 }.
        The states 1 and 2 are together because they cannot be distinguished by 'a', but
        the fallback transition distinguishes them.

        Since we have done every other split, we have one useful property: we know that every
        state in every set transition with the exact set of characters within that set.
        If that was not true, there would be one "distinguisher" 'x' that could spit the set
        into two subsets: the one with the transition 'x' and the ones without.

        Since all the transitions are the same, there is no overlap between the defined transition
        and the fallback transition. Consequently, we can use the fallback transition as a whole
        transition and use it to distinguish the states.

        The fallback transitions are handled like any other transition, we have a partition of such
        transitions and split by each of them. BUT, we can only use them after every unique transition
        has been covered.

        This trick is also what makes the minimization imperfect: it should be possible to merge
        states with overlap in their fallback transitions but we would split them.

        ASSERT(frame().view() == this) assertion hit in FrameView::windowClipRect() on Windows bots

        Reviewed by Brent Fulgham.

        ASSERT(frame().view() == this) in FrameView::windowClipRect() can be hit
        if the post layout timer timer fires after the page has entered page
        cache. Upon entering page cache, we call FrameView::unscheduleRelayout()
        to stop the layout timer if it is active, however, we don't stop the
        post-layout timer. Therefore, there was nothing preventing the
        post-layout timer from firing after entering page cache.

        In this patch, we unschedule the post-layout timer in
        FrameView::unscheduleRelayout() to protect ourselves against this.

        I think we were only seeing the assertion hit on Windows because this
        timer probably gets scheduled more frequently on Windows. On Mac, I
        rarely see it getting scheduled.

        [CSS Grid Layout] Columns set in percentages collapse to auto width
        https://bugs.webkit.org/show_bug.cgi?id=141435

        Reviewed by David Hyatt.

        Based on a patch by Sergio Villar Senin  <svillar@igalia.com>.

        This patch adds 2 new new methods in RenderBox to determine if the grid
        has a definite size or not.

        RenderGrid::gridTrackSize() was not checking properly if the grid has or
        not an indefinite size.
        The condition was including auto which is not indefinite per se. For
        example, auto is definite if the containing block is definite.
        As the new method is more expensive, we just call it when it's really
        needed to avoid performance regressions.

        Finally we were setting the override logical width/height to -1 (no
        possible resolution) for all the items regardless if they've a relative
        width/height or a fixed one.
        Added the condition, including not only items with percentage logical
        width/height but also relative, to avoid overriding the value for items
        with fixed width/height as it's not needed.

        Regression: Scrolling on popsci.com spends too much time in FrameView::viewportsContentsChanged()
        https://bugs.webkit.org/show_bug.cgi?id=143675

        Reviewed by Simon Fraser.

        Optimize resumeVisibleImageAnimationsIncludingSubframes() so that the FrameViews'
        windowClipRect gets computed less often:
        - Cache the FrameView's windowClipRect before resuming image animations in subframes
          as calling windowClipRect() on those subframes' view is going to call windowClipRect()
          on their ancestors. This avoids a lot of unnecessary windowClipRect recomputations
          in deep frame trees.
        - Stop traversing the Frame tree if the current frame does not have a content
          renderer, as this means the subframes won't have one either.
        - Stop traversing the Frame tree if the current frame's view has an empty
          windowClipRect() as this means the windowClipRect will be empty for those
          subframes as well.

        On popsci.com, this cuts down the number of uncached windowClipRect() calls by
        approximately half. I see viewportsContentsChanged() at ~0.4% when scrolling
        on popsci.com after this change.

        [Win] Unreviewed fix after r182161.

        The change caused Windows to lose Media UI, since the new 'getFileSize'
        signature was being improperly used for a 'UInt8'-based string.

        Fix was to provide implementations for the two new methods, and to make
        sure RenderThemeWin was using the proper signature.

        This should actually be a little more efficient, since we have the file
        handle when we call this new method. Previously, a Windows 'find file' was
        being done with the requested path, which was unnecessary work.

        Canvas drawImage() has a security hole when the image isn't yet fully loaded.
        https://bugs.webkit.org/show_bug.cgi?id=58681.

        Reviewed by Darin Adler.

        There is a race condition which may happen if an image from a different
        origin is drawn on a canvas before it finishes loading. The check to taint
        the canvas comes before drawing it. This check returns false if the image
        is not completely loaded because we check the URL of the resource response.
        If after this check and before the drawing, the image finishes loading, the
        canvas will not be tainted but the image will be drawn.
        
        The fix is to move the check to taint the canvas after drawing the image.
        The only problem with this solution is basically the opposite of this bug:
        we will become stricter than before with images which are from a different
        origin and before they finish loading. The image has not finished loading,
        so we do not draw it. Before we check for tainting, the image finishes
        loading. So we decide to taint the canvas even the image is not drawn.
        
        But this should not be a security issue anymore. I personally do not know
        if it is even a correctness issue or not.

        Our "don't do layout if transform changes" code was too aggressive.
        If an element changes between having a transform and not having one, we
        really need to do a layout since so much else depends on transforms. In
        this particular case, we clip position:fixed elements to the viewport if
        they are not transformed, and were failing to re-evaluate this when a
        transform was added. Doing a layout fixes this.

        Most lines of code in CurlCacheEntry::parseResponseHeaders() don't need to be
        executed if the response has "no-cache" or "no-store" directive, but we are
        checking these conditions in the middle of the method. We can move this to the

        [CSS Grid Layout] Support marking/unmarking tracks as infinitely growable
        https://bugs.webkit.org/show_bug.cgi?id=141431

        Reviewed by Darin Adler.

        As explained here
        http://lists.w3.org/Archives/Public/www-style/2014Mar/0512.html we
        sometimes need to consider that some tracks are infinitely
        growable even when they are really not, in order to produce more
        "natural" results.

        For example the following case:
          grid-template-columns: auto auto;
          item 1 in column 1 with min-content = max-content = 10px;
          item 2 in columns 1-2 with min-content = 30, max-content = 100px;

        will produce (45px, 55px) without this patch. But considering the
        second column as infinitely growable the result is (10px, 90px), a
        more "natural" result because column 1 just needs to be 10px to
        accommodate item 1. From now on we can flag GridTracks so that
        they can infinitely grow even when the growth limit is finite.

        Apart from that distributeSpaceToTracks() is now unconditionally
        called even though the extra space is 0. That's because it
        computes the plannedSize value.

        This is wrong; we only need to issue repaint for the slow-repaint renderers,

        Simple line layout: Add <br> support.

        [Mac][WebAudio] Update the AVAudioMix in the AudioSourceProviderAVFObjC when the list of enabled audio tracks change.
        https://bugs.webkit.org/show_bug.cgi?id=143332

        Reviewed by Eric Carlson.

        Some media assets (notably, mp3s) will not have an enabled audio track when the AVAsset is
        first loaded, so the AVAudioMix will have no trackID in it's parameters. Whenever the list
        of enabled tracks change, recreate the AVAudioMix with the new first enabled audio trackID.

        To facilitate this, add a new setter to AudioSourceProviderAVFObjC taking an AVAssetTrack to
        use with the AVAudioMix. Whenever this parameter changes, the AVAudioMix is destroyed and

        This is a case we claim to support, but it only works if the
        object has only one reference. In that case, when the user unrefs
        it, the weak ref notify callback removes the object from the
        cache. However, if the object has more than one ref, the cache
        doesn't know the user unreffed it, and when clearing the cache we
        try to remove more references than what the object actually has,
        causing a crash in g_object_unref.

        Open WebSockets should not prevent a page from entering PageCache. This
        is currently causing mobile.nytimes.com to not be page-cacheable.

        In this patch, We close open WebSockets when entering the page cache
        and fire the "close" events after resuming, similarly to what we did
        for XMLHttpRequest in r181480. This gives a chance for the content to
        handle the 'close' event (with wasClean being false and code being
        1006) in order to reopen the connection if necessary.

        Add experimental code to use custom font dilation when rendering into non-opaque contexts
        https://bugs.webkit.org/show_bug.cgi?id=143508

        Reviewed by Sam Weinig.

        Add GraphicsContext::setAntialiasedFontDilationEnabled(), and set it to true
        when rendering into a compositing layer which is not opaque (at the same location
        where we disable font smoothing).

        If Settings::antialiasedFontDilationEnabled() is true, when rendering non-smoothed
        text (and if CSS hasn't opted into antialiased mode), use custom font dilation
        parameters, chosen using a light/medium/dark heuristic, to make this text

        [Cocoa] System fonts do not get correct tracking
        https://bugs.webkit.org/show_bug.cgi?id=143395

        Reviewed by Ryosuke Niwa.

        Inside FontPlatformData, we have two CTFonts. If the user has specified
        -webkit-system-font, we will pass in a CTFont, and the FontPlatformData
        will wrap it. However, we will then roundtrip through CGFont in order
        to create a second CTFont. We were basing our tracking and system
        font knowledge off of this round-tripped font instead of the original font.

        Note that this design is terrible and needs to be overhauled.
        FontPlatformData should only have a single platform font inside it.

        This patch also caches whether or not a font is a system font.

        No new tests because it is impossible to test the tracking of the
        system font in a robust way.

        [CSS Grid Layout] Update track sizes after distributing extra space
        https://bugs.webkit.org/show_bug.cgi?id=141422

        Reviewed by Antti Koivisto.

        Both old and new tracks sizing algorithms instruct us to update
        the sizes of the content sized tracks only after distributing the
        extra space for all the items in the same span group. So far we
        were doing it inside distributeSpaceToTracks(), i.e., once for
        every single item. That is wrong because it makes the algorithm
        order dependent.

        Our old implementation looked something like this (pseudocode):

        resolveContentBasedTrackSizingFunctions()
          foreach item
            resolveContentBasedTrackSizingFunctionsForItems() (x4)
              distributeSpaceToTracks()
                updateTrackSizes()

        Now it's done this way (pseudocode):

        resolveContentBasedTrackSizingFunctions()
          foreach spanGroup
            resolveContentBasedTrackSizingFunctionsForItems() (x4)
              foreach item in spanGroup
                distributeSpaceToTracks()
              updateTrackSizes()

        As it can be seen the update of track sizes only happens after
        processing all the items of a given span group. In order to
        accomplish this a new field was added to GridTrack called
        tempIncrease which stores per-track increases while distributing
        the extra space among the items in the same span group. That
        temporal increase could eventually be used to update the
        plannedIncrease which is the one we use to finally set the new
        size of the track.

        This change makes our implementation closer to the spec, removes
        the order dependency and ensures that every track satisfies their
        min track sizing functions before starting to consider the max
        track sizing functions.

        It now receives a span group instead of a single item. Apart from
        that we need an extra function to get the unaltered track size (as
        the current one returns the base size whenever the growth limit is
        infinity).

        Bing video search result pages are not PageCacheable
        https://bugs.webkit.org/show_bug.cgi?id=143463
        <rdar://problem/20440916>

        Reviewed by Alexey Proskuryakov.

        Bing video search result pages are not PageCacheable (tested on iOS).
        It both:
        - is bad for power usage as it causes a reload when clicking one of the
          results then navigating back in history.
        - degrades user experience because the results page uses infinite
          scrolling and the scroll position is not properly restored when
          navigating back, not to mention the user has to wait for the reload
          to complete.

        The issue was that the bing search page was doing a ping load when
        clicking on one of the search results. The ping load was done by
        create an image and its 'src' attribute to the ping URL. This load
        usually did not have time to complete when navigating away so we would
        cancel it and the main document would end up with an error that would
        prevent the page from entering the page cache. We already have code
        making sure load cancellations do not prevent page caching as long as
        the loads are for XHR or images. However, the latter check was broken
        in the case where the ResourceRequest's cachePartition was non-empty.
        This is because the check was using the MemoryCache::ResourceForUrl()
        API which rarely does what we want because it will request a dummy
        ResourceRequest (without cachePartition) and then call
        MemoryCache::resourceForRequest(). This patch updates the check
        to use resourceForRequest() directly as we have the ResourceRequest
        at this point.

        This patch also gets rid of the  MemoryCache::ResourceForUrl() API as
        it rarely does what we want and it is bug prone. It was only used in
        2 places, one of them causing this bug and the other in Internals.

        Tests: http/tests/navigation/page-cache-pending-image-load-cache-partition.html

        * loader/DocumentLoader.cpp:
        (WebCore::areAllLoadersPageCacheAcceptable):
        Use MemoryCache::resourceForRequest() instead of resourceForUrl() as
        we have the ResourceRequest and calling resourceForUrl() would loose
        the cachePartition.

        * loader/cache/MemoryCache.cpp:
        (WebCore::MemoryCache::resourceForURL): Deleted.
        Drop this API as it is bug prone and rarely does what we want.

        * testing/Internals.cpp:
        (WebCore::Internals::isLoadingFromMemoryCache):
        Update call to create a dummy ResourceRequest and call
        resourceForRequest() instead of resourceForUrl(), as this API no
        longer exists. The new code also set the cachePartition on the
        dummy request so that this function actually behaves as expected
        if the cachePartition in the memory cache is non-empty.

        Synchronize fullscreen animation between processes.
        https://bugs.webkit.org/show_bug.cgi?id=143131

        Reviewed by Simon Fraser.

        Rather than attempt to synchcronize animations across the WebProcess / UIProcess boundary,
        do the bounds-change animation in-process by applying a sublayer transformation to the
        video layer. This gives the same visual effect as a synchronized bounds animation, but
        without needing a synchronization fence. Resolve the difference between the transformation
        and bounds by doing a fence-synchronized bounds change after the current animation is
        scheduled to complete.

        To do this calculation correctly, WebAVPlayer needs to query both the effective
        videoLayerFrame and the videoLayerGravity. To that end, add getter methods for
        videoLayerFrame() and videoLayerGravity().

        [Content Filtering] Blocked page is not always displayed when it should be
        https://bugs.webkit.org/show_bug.cgi?id=143410
        rdar://problem/20211099

        Reviewed by Andreas Kling.

        These tests now pass: contentfiltering/block-after-add-data.html
                              contentfiltering/block-after-response.html

        There were several problems with how ContentFilter loaded replacement data:
        (1) Replacement data was delivered to DocumentLoader as if it were the original document's data. This assumes
            that the original data was a UTF-8 encoded HTML document, which is not always true. We had a way to reset
            the encoding, but not the content type.
        (2) Replacement data was never delivered when the filter blocks in DocumentLoader::responseReceived().
        (3) The main resource load was cancelled before the replacement data could be rendered when the filter blocks
            in DocumentLoader::dataReceived().
        The result was that only when the load was blocked after DocumentLoader::notifyFinished() would the replacement
        data be shown properly, and only when problem (1) wasn't occurring.

        This patch addresses these issues by using the substitute data mechanism to deliver replacement data. By using
        substitute data, we can ensure that the original load is cancelled at the earliest opportunity and that the
        replacement data is loaded with the proper content type and encoding.

        Accomplishing this required changing the way ContentFilter interacts with DocumentLoader. Instead of placing
        ContentFilter hooks throughout DocumentLoader, this patch makes ContentFilter itself the client of the
        CachedRawResource for the duration of the filtering. If the filter decides to allow the load, DocumentLoader
        adds itself as a client causing CachedRawResource to deliver to it the response and buffered data. If the
        filter decides to block the load, DocumentLoader schedules a substitute data load. An added benefit of this
        approach is that ContentFilter can reuse CachedRawResource's original data buffer instead of keeping its own.

        AX: Heuristic: Avoid exposing an element as clickable if mouse event delegation is handled on an AXElement with more than one descendant AXElement

        Modify the logic for determining whether an element supports the press action by trying to filter out objects being handled by event delegation.
        The heuristic is if an element handles click actions and has more than one of a {static text, image, control, link, heading}, then we think
        it's using event delegation, and do not expose the press action.

        Streamline icon-related code, mostly unused

        Reviewed by Antti Koivisto.

        I started on this path because Document::iconURLs had a poor implementation,
        storing results in a data member with no benefit, using HTMLCollection for
        iteration of the children of the head element instead of using the simpler
        faster technique we use inside the engine. Then, I discovered this function was
        mostly-unused code left over from before the Blink fork. I removed most of it.
        We can add this back later if someone finds a use for it, but if we do we
        should do a higher quality implementation without the quirks of the old one.

        Refactoring also made it clear that logic isn't exactly sensible. There's a
        set of rules about what order to return the list in that is not followed by
        the code that tries to find the "default touch icon". Later we could add some
        more test coverage and tighten up the logic. But the reality is that at this
        time, with some small exceptions, icon logic is in the web browsers, not in WebKit.

        Calling computeNonFastScrollableRegion() eagerly when scrollable areas come and go
        is bad, because it can cause FrameView::layout() to get called in the middle of

        Fix by calling computeNonFastScrollableRegion() lazily, just before scrolling tree commit.
        
        AsyncScrollingCoordinator::frameViewNonFastScrollableRegionChanged() now just sets
        a flag to say that the non-fast region needs to be recomputed, and that schedules
        a scrolling tree commit. When the commit happens, we recompute the region. If the
        region didn't change, and no other changes are pending, there's no need to commit.

        ScrollableArea::usesCompositedScrolling() meant "uses aysnc scrolling", but
        FrameView::contentsInCompositedLayer() covered a related concept, that scrolling
        happens by moving compositing layers around.
        
        Make the difference between these more explicit by adding ScrollableArea::usesAsyncScrolling(),
        which means that scrolling for that ScrollableArea is asynchronous and managed
        by a ScrollingCoordinator. This is the meaning that ScrollingCoordinator::computeNonFastScrollableRegion()
        understands.
        
        ScrollableArea::usesCompositedScrolling() is now repurposed to mean "scrolling
        occurs by moving layers around, not requiring repaint". FrameView::contentsInCompositedLayer()
        is renamed to usesCompositedScrolling(), and overrides the base class function.

        This only changes behavior in tests that call setScrollingTreeIncludesFrames(true).

        REGRESSION: Caption Menus show language codes instead of display names.
        https://bugs.webkit.org/show_bug.cgi?id=143350
        <rdar://problem/20094145>

        Reviewed by Jer Noble.

        The generic caption/track label handling in CaptionUserPreferences does not convert language codes
        (e.g. 'fr-CA') into display names (e.g., 'French (Canada)'). Because we did not have an AudioTrack
        override to process these types of menu items, they were being handled using the generic code.

        Disallow ruby base from having leading or trailing expansions
        https://bugs.webkit.org/show_bug.cgi?id=142608

        Reviewed by David Hyatt.

        If we determine that a ruby base should have either a leading or trailing expansion,
        we shunt that expansion over to the neighboring RenderText, assuming one exists. This
        requires that we teach RenderText how to force leading or trailing expansions if one
        wouldn't naturally be present.

        WebRTC: Add support for Promise-based MediaDevices.getUserMedia()
        https://bugs.webkit.org/show_bug.cgi?id=143255

        Reviewed by Eric Carlson.

        The MediaDevices object collects functionality related to local media
        devices. This patch adds the Promise-based version of getUserMedia()
        (unprefixed). Other functionality, like enumerateDevices(), will be
        added in later patches.

        The old callback-based webkitGetUserMedia() (on Navigator) is kept for
        legacy purposes (according to the Media Capture and Streams API spec [1]).
        Both versions of getUserMedia are backed up by UserMediaRequest where
        the callbacks from the callback-based version are wrapped inside c++
        lambda functions. The new Promise-based getUserMedia() uses the lambda
        functions directly as created by the Promise bindings.

        [CSS MultiColumn] Parse "columns: auto <length>" shorthand property value properly

        Reviewed by Darin Adler.

        The two longhands for the 'columns' property ('column-count' and
        'column-width') may both take 'auto' as a value. When we encounter
        'auto' during parsing the value list of a declaration, we cannot just
        make a guess at which property/properties that's meant for. Instead,
        don't assign anything to 'auto' right away, but wait until all values
        have been processed and at that point set the still unassigned
        properties to 'auto'. If 'auto' isn't in the value list at all, set
        unassigned properties to 'initial' for the 'columns' property, just
        like we do for any other property.

        Async loading of image resources
        https://bugs.webkit.org/show_bug.cgi?id=134488

        Reviewed by Dean Jackson.

        This patch changes image loading to be asynchronous (per spec), in order
        for it to be agnostic to property setting order when it comes to src, srcset and crossorigin,
        as well as to enable future hooking of the <picture>-based selection logic on top of it.

        Remove the wheel event counting that Document does, and passes into the scrolling tree.
        The ScrollingTree now just uses the non-fast scrollable region to determine when to
        fast scroll on pages with wheel event handlers.
        
        If a handler includes position:fixed renderers, we just cover the whole document
        with the slow-scrolling region currently. This could be improved.

        Migrate ExpansionBehavior to an enum comprised of two values: one for leading behavior

        "force," "forbid," and neither. All calls that interact with justification are
        migrated to use this new structure.

        Note that in this terminology, "leading" and "trailing" are with respect to the order
        that elements get laid out in a line. Therefore, leading is always on the left, since
        lines get laid out that way regardless of their bidi attributes.

        Lots of time spent querying table cell borders, when there are none.
        https://bugs.webkit.org/show_bug.cgi?id=143277

        Reviewed by Simon Fraser.

        This patch speeds up collapsed border queries by using existing collapsed border
        cache to calculate repaint rects and by introducing a fast path for zero width collapsed borders.

        It reduces the number of calls to recompute collapsed borders from 36 000 to 1 600, while loading a page with a table of 400 rows (1 cell per row).
        When scrolling the same page all the way down to the bottom, the number of calls to recompute collapsed borders falls from 290 000 to 0.

        Use GStreamer's glimagesink for video rendering instead of our
        custom video sink if a recent-enough version of GstGL is found
        during the build. When glimagesink is used it passes a texture to
        the media player which then wraps it inside a TextureMapper
        texture later used for actual rendering.

        Using this new code path will allow us to remove our custom sink

        Make it possible to compute a region for elements on the page that have wheel event handlers
        https://bugs.webkit.org/show_bug.cgi?id=142807

        Reviewed by David Hyatt.
        
        Make it possible to compute a region that covers the elements on the page that have
        a wheel event handler. This region may overestimate, but must not underestimate the area.
        
        Elements with wheel handlers are registered on the document, and when a document gains
        its first wheel handler, it registers the ownerElement in the parent document. Thus, on 
        the main frame, the region encompasses elements with handlers, and iframes whose subdocuments
        have handlers.
        
        Element gains some functions that allow it to return a rect which is the bounds of the element's
        renderer, and renders for its descendant elements, which is the size or larger than the event
        handling region for that element. Some configurations (e.g. position:fixed) require special
        treatment.
        
        Document::absoluteRegionForEventTargets() can then iterate over all elements in the given set,
        and build a Region for those (short-circuiting if the document itself has a handler).
        
        The new code is exercised for the debug MouseWheelRegionOverlay, and also added to the
        non-fast scrollable region, used by threaded scrolling.

        Content Extensions: split the state machines to minimize prefix states
        https://bugs.webkit.org/show_bug.cgi?id=143253

        Reviewed by Alex Christensen.

        With this patch, we refine how the URLs are partitioned to make
        multiple small machines instead of a big one.

        Here, considering each pattern as a language, I took the simplest
        partitioning: take the union minimizing the states
        that differentiate languages.

        The idea is the following: every time a subgraph can be skipped
        or repeated, it is an opportunity for a merged language to start
        with a distinguishable state.
        To avoid accumulating those differences, we only merge languages
        that share the exact same "variable" subgraph as a prefix.

        A side effect is that we could create as many machines as we have patterns.
        We'll have to address that in a follow-up by merging small machines
        until they reach a certain size.
        In the common cases, patterns look very much alike so that is not a problem
        at the moment.

        I moved the prefix tree and graph construction out of URLFilterParser for clarity.

        CombinedURLFilters maintain the term prefix tree. Instead of generating on the fly
        as we build the prefix tree, we first generate the entire tree of terms, then generate
        NFAs for each branch without a variable prefix.

        Note here that we keep track of which subtree contains a any variable length term.
        Instead of anotating the edges, the destination vertex is anotated with the information
        from the edge.

        The flag "inVariableLengthPrefix" is there to simplify traversal.

        (WebCore::ContentExtensions::CombinedURLFilters::createNFAs):
        Since we are traversing a tree generated by string, using the stack for recursion
        is out of the question.

        Fortunately, the entire state is very simple when going depth first: we only need
        the active vertex and edge, and traverse the edges in order.

        To do keep track of the edges, I used the HashTable iterator on the current term.
        Since no vertex is modified for generation, storing the iterators is safe.

        Reviewed by Simon Fraser.

        The change that caused this regression was correct. That change does not allow 
        RenderLayer to update scroll position after a layout if a rubber-band is currently 
        happening. The change caused this regression because all of the member variables 
        in ScrollController that attempt to keep track of the current state of the scroll 
        gesture (m_inScrollGesture, m_momentumScrollInProgress, and 
        m_snapRubberbandTimerIsActive) all indicated that a momentum scroll gesture was 
        still in action for this div even though it very much is not when the bug happens. 
        Those variables were never properly re-set because the 
        PlatformWheelEventPhaseEnded events never got dispatched to the ScrollController, 
        which brought the investigation back to Element.

        We must still dispatch events that have zero delta so that the default event 
        handlers can handle them, but we should stopPropagation() so that these events are 
        not sent to the DOM. Websites will break if they get wheel events with no delta.

        Web Inspector: add 2D/WebGL canvas instrumentation infrastructure
        https://bugs.webkit.org/show_bug.cgi?id=137278

        Reviewed by Timothy Hatcher.

        Added backend agent for canvas inspection. A canvas is instrumented once its CanvasRenderingContext has been
        created. WebGLRenderingContext is instrumented to track the lifetime of shader program objects.

        To instrument off-screen rendering contexts (CSS canvases and detached canvas elements), the canvas agent must
        track all CanvasRenderingContexts as they are created, even in the absense of the frontend. As far as I know,
        there is no practical way to identify rendering contexts belonging to a frame that are not in the DOM. In the
        absence of the inspector frontend the agent does only the minimum required to track the lifetime of rendering
        contexts and their resources, to avoid creating a negative performance impact.

        [Streams API] Implement a barebone ReadableStreamReader interface
        https://bugs.webkit.org/show_bug.cgi?id=142866

        Reviewed by Benjamin Poulain.

        This patch implements a barebone ReadableStreamReader as described in https://streams.spec.whatwg.org/#reader-class.
        It implements the IDL without implementing most of the functionality behind.
        It implements ReadableStreamReader JS constructor and the link with ReadableStream.getReader:
        - Raise an error if stream is already locked
        - Set the stream reader to the newly created ReadableStreamReader instance.

        Cached "Expires" header is not updated upon successful resource revalidation
        https://bugs.webkit.org/show_bug.cgi?id=143228
        <rdar://problem/20348059>

        Reviewed by Antti Koivisto.

        Cached "Expires" header was not updated upon successful resource
        revalidation. This affected both our disk cache and our memory cache.
        This was caused by shouldUpdateHeaderAfterRevalidation() in
        CacheValidation.cpp returning false for the "Expires" header.

        There is a comment there stating that the list of ignored headers
        matches Chromium's net library but that's not the case, at least not
        anymore:
        http://osxr.org/android/source/external/chromium/net/http/http_response_headers.cc

        HTTP servers such as Apache return an "Expires" header in their 304
        responses and the "Expires" header is potentially a new one. However,
        our caches were ignoring the updated expiration date and kept using the
        old one, which meant that the cached resource expired sooner than it
        should have.

        See the following Apache bugs that explain the issue:
        https://bz.apache.org/bugzilla/show_bug.cgi?id=24884

        Broaden justify-self's parsing name

        This is in preparation of migrating align-self, align-items
        and justify-items to the CSS 3 Alignment syntax.

        The current naming was too tied to justify-self and needs to
        be broadened. This will reduce the follow-up implementations'
        patches.

        Upgrade align-self and align-items parsing to CSS 3

        This change migrates the 2 properties to the CSS 3 Alignment
        parsing. The new parsing is identical to how we parse
        'justify-self'. The 2 properties need to be migrated together
        as they are used in tandem in CSSComputedStyleDeclaration.

        This change also removes EAlignItems as it is now unused.

               webaudio/audiocontext-state.html

        Implement the following methods and properties from the Web Audio spec:
        close(), suspend(), resume(), onstatechange.

        AudioContext will take more responsibility for tracking state and interruptions (and
        AudioDestination will give up that responsibility). This means AudioContext must be a
        MediaSessionClient, and own its own MediaSession. In return, AudioDestinationIOS and 
        AudioDestinationMac relinquish both.

        `currentColor` computes to the same colour on all elements, even if 'color' is inherited differently
        https://bugs.webkit.org/show_bug.cgi?id=133420

        Reviewed by Darin Adler.

        When resolving a style with the help of the property cache, we were
        completely ignoring currentColor.

        Since you can set currentColor on properties that are not inherited,
        those properties would just be copied from the cached style, which
        may have a completely different inherited color.

        This pacth fixes the issue by preventing any MatchResult from hitting
        the cache if it contains any non-inherited property that would require
        resolution by the cache:
        -Using the inherit value.
        -Using the currentColor value.

        Remove unneeded SVG code, including most isSupportedAttribute functions
        https://bugs.webkit.org/show_bug.cgi?id=143194

        Reviewed by Antti Koivisto.

        - Removed most implementations of isSupportedAttribute. Others can be removed in
          future patches. The ones left behind are now all private static member functions.
          It's dangerous for them to be public because they tend to indicate which attributes
          are supported at a particular level in the class hierarchy and they are not virtual
          functions; might want to rethink the function name if we keep any of these long term.

        - Removed unneeded includes, especially of Attr.h and Attribute.h.

        - Changed most parseAttribute and svgAttributeChanged functions so they no longer
          rely on checking attribute names against a set. Also removed lots of unneeded calls
          to SVGLangSpace::parseAttribute, which is called by SVGElement::parseAttribute and
          need not be called by derived classes.

        - Removed return values from parseAttribute functions. Skipping other parseAttribute
          logic is not an important optimization and makes functions needlessly complex.

        - Moved use of InstanceInvalidationGuard closer to where they are needed. Eventually
          we may be able to remove many of these.

        - Used auto in a few places where the same type is repeated twice on the same line of
          code, and auto makes it a bit smaller.

        - Got rid of protected sections in some final classes; doesn't make sense to combine
          these two. Also moved a few functions from protected to private in other classes.

        - Made a number of functions into static member functions in the base classes such
          as SVGLangSpace; they were not making any use of the object, and so it was wasteful
          to compile them as non-static member functions.

        [TexMap] Seperate BitmapTexture related classes implementations from TextureMapper
        https://bugs.webkit.org/show_bug.cgi?id=142386

        Reviewed by Žan Doberšek.

        TextureMapper and TextureMapperGL are bloated and tightly coupled with
        BitmapTexture. We should move these classes to seperated file of their own.
        Also, this patch removes friend relationship from TextureMapperGL and  its
        subsidiary classes.

        The main purpose of this refactoring is to expose BitmapTexturePool to
        renderers of platformlayers like Video and Canvas. By doing this, each
        renderer can acquire textures from the global texture pool to paint
        their contents directly.

        No new tests needed.

        Bind used TextureMapperGL's internal data directly to compute projection matrix as a friend class,
        However, TextureMapperGL can compute projection matrix itself after binding job, so this
        friend ship is not needed. Also, this patch renames Bind to BindAsSurface to remove ambiguity.

        Calling DataDetectorsLibrary() is expensive; we should avoid doing it

        ServicesOverlayController was calling DataDetectorsLibrary() (ignoring the fact
        that a caret selection can't have any services associated with it) to avoid
        crashing on systems where DataDetectors is not available. Instead, we should

        Test: media/video-page-load-preload-none.html

        When told to load() when preload == None, set the networkState to Idle.
        This causes HTMLMediaElement to set the shouldDelayLoadEvent flag to
        false, and allows the page's 'load' event to fire.

        [GStreamer] share GL context in pipeline, part 2
        https://bugs.webkit.org/show_bug.cgi?id=143049

        Reviewed by Carlos Garcia Campos.

        This patch, instead of cluttering the GstGL attributes creation in
        ::handleSyncMessage(), creates a new method ::ensureGstGLContext(),
        where those attributes are defined. This method is guarded by
        USE(GSTREAMER_GL)

        ::handlSyncMessage() shall return nothing, according to GStreamer
        documentation, not a boolean.

        The GstGL attributes are now GRefPtr<> to avoid memory leaks.

        The GstGLAPI and GstGLPlatform are now set given by the pre-processor
        directives, and the code in ::ensureGstGLContext() is simpler.

        No new tests because this is platform specific and it depends in the
        run-time availability and configurations of GstGL elements.

        Optimized Fullscreen fails to cleanup because of no longer necessary release of m_playerController in exitFullscreen()
        https://bugs.webkit.org/show_bug.cgi?id=143120

        Reviewed by Eric Carlson.

        We used to release m_playerController in WebVideoFullscreenInterfaceAVKit::exitFullscreen() in order to make sure 
        media state was reset. This is no longer necessary as we now have a way the model can explicitly request resetting the
        media state via resetMediaState(). m_playerController is already released in 
        WebVideoFullscreenInterfaceAVKit::cleanupFullscreenInternal(). Releasing it prematurely can actually prevent the exit
        fullscreen process from completing successfully.

        It's wrong to assume that when RenderInline is part of an inline continuation, its containing block
        is an anonymous wrapper and its sibling might be a block level renderer.
        When the inline continuation is no longer needed, for example when the block level renderer that initiated the continuation
        is detached from the render tree, the inline renderes still continue to form continuation.(however they no longer require
        anonymous wrappers)

        Relevant repainted objects callback is inaccurate and inconsistent for PDF

        Reviewed by Tim Horton.

        Investigating this bug resulted in finding two things that should change for the 
        relevant repainted objects heuristic. First, we should not count any objects 
        painted while updating control tints. And secondly, we should not use it at all 
        for plugin documents. In other documents, we count the plugin area as “painted” 
        when we get to paint whether or not the plugin has actually loaded. This is 
        intentional because it allows us to account for chunks of the page that will be 
        filled in by possibly slow-loading ads. However, if the plugin is the whole 
        document, then the heuristic just doesn’t make any sense and it leads to 
        inconsistent behavior at different window sizes. So we’ll only count plugins when 
        the document is not a plugin document. 

        Don’t count objects during this paint!

        Make URL filter patterns matching consistent and add a simple canonicalization step
        https://bugs.webkit.org/show_bug.cgi?id=142998

        Reviewed by Alex Christensen.

        This patch makes two changes to the url filter input:
        -Make the matching "Search" by default, the pattern can now appear anywhere
         in the URL by default.
        -Make the input a little less fragile: do not explode on valid input
         that is not formatted in a certain way.

        To implement the search behavior, I simply add an implict ".*" in front of the patterns
        when that make sense.

        To make the input more solid, we do some little modification on the input:
        -Remove duplicated ".*".
        -Remove matching suffixes that do not bring new information.
        -Unify all the ".*" in the same format.

        Why do that here? That should be done through a graph analysis on the machine.

        The reason is this is incredibly cheap compared to the graph analysis. Any state
        removed upfront will save the handling of several hundred nodes in the deterministic
        graph.

        -and corresponding-
        rdar://problem/20210239

        Reviewed by Dean Jackson.

        This patch adds six new events for the force click gesture:

        webkitmouseforcewillbegin -> Event is sent just before mousedown to indicate that 
        force can be perceived if the user presses any harder. The author should prevent 
        default on this event to both prevent the user agent’s default force click 
        features and to receive the other 5 events.

        webkitmouseforcechanged -> This event fires whenever force changes between the 
        mousedown and mouseup. It is a new type of mouse event that includes a force 
        variable which is a normalized number between 0 (corresponds to click) and 1 
        (corresponds to force click). In this patch, I have only added code to send this 
        event between mousedown and mouseforcedown, but as a followup patch, we plan to 
        send it through mouseup.

        webkitmouseforcecancelled -> If the user releases their finger from the trackpad 
        after pressing hard enough to send webkitmouseforcewillbegin events but not hard 
        enough to force click, this event will be sent to indicate that the user bailed 
        out on the gesture.

        webkitmouseforcedown -> The down part of the force click.

        webkitmouseforceup -> The up part of the force click. This event is added in this 
        patch, but does not yet fire. That is work for a follow-up patch.

        webkitmouseforceclick -> The equivalent of the click event for the force click. 
        Should fire just after webkitmouseforceup. This event is added in this patch, but 
        does not yet fire. That is work for a follow-up patch.

        Update empty image canvas tests and fix a related bug
        https://bugs.webkit.org/show_bug.cgi?id=142694

        Reviewed by Chris Dumez.

        During the work on https://bugs.webkit.org/show_bug.cgi?id=142677
        we encountered an issue with canvas tests related to empty image handling
        when drawn or used as a pattern. After updating these tests, an issue with
        pattern handling was encountered.

        The spec, as well as Chrome's implementation, say that when an empty image
        is used as a pattern, createPattern should return null. See
        https://html.spec.whatwg.org/multipage/scripting.html#fill-and-stroke-styles:check-the-usability-of-the-image-argument
        Instead, createPattern returned an exception in this case.
        This patch fixes that and makes sure that it returns a null when image loading hasn't started.

        Scroll latching logic can get stuck in 'scrollable="no"' iframes
        https://bugs.webkit.org/show_bug.cgi?id=142789
        <rdar://problem/20129494>

        Reviewed by Dean Jackson.

        Clean up the EventHandler and latching code as follows:
        (1) Do not handle iframe elements as part of the normal latching logic. Instead, iframes should
            be evaluated during the 'platformCompleteWheelEvent' phase of processing as top-level scrolling
            frames.
        (2) Get rid of the ill-conceived notation that we should process non-mainframe and main-frame frames
            different.
        (3) Modify code to reflect that the scroll latching code really deals with overflow scrolling. Consequently,
            the 'findEnclosingScrollableContainer' was renamed to 'findEnclosingOverflowScroll' and does not
            treat iframe as a suitable target.
        (4) Do not create a latching state object when the container being evaluated is already scrolled to the
            extreme position in the direction of the mouse gesture. In this case, we want the enclosing frame
            to be the latching target.
        (5) Do not treat the state where the mouse wheel gesture has ended manual scrolling, but has not ended
            momentum scrolling, as an appropriate time to select a latching target.

        For transform-style, we also still differentiate the prefixed property

        Regression(r181782): Caused WebKit2.RestoreSessionStateContainingFormData API test to crash

        Reviewed by Antti Koivisto.

        Drop the isBackForwardLoadType(m_loadType) assertion in
        FrameLoader::retryAfterFailedCacheOnlyMainResourceLoad(). This assertion
        used to hold true when goToBackForwardItem() was only called with
        history navigation load types. However, after r181782, we use a Standard
        load in the cases where we do not wish to display stale content (e.g.
        restoring session state).

        The assertion comment says "We only use cache-only loads to avoid
        resubmitting forms". However, we then call loadDifferentDocumentItem()
        which already takes care of using the ReturnCacheDataElseLoad cache
        policy as the HistoryItem has form data and we pass
        MayNotAttemptCacheOnlyLoadForFormSubmissionItem as parameter.

        No new tests, covered by WebKit2.RestoreSessionStateContainingFormData
        API test.

        [Content Filtering] Add tests for unblock requests
        https://bugs.webkit.org/show_bug.cgi?id=142900

        Reviewed by Andreas Kling.

        Currently the iOS Parental Controls content filter has a mechanism for requesting that a page be unblocked.
        WebKit implements this by listening for navigations originating from the filter's error page to a special URL,
        and requesting the page be unblocked via platform API, which might cause UI to be displayed. If the unblock is
        successful then we schedule a reload of the frame in order to display the unblocked document.

        NetworkExtension also supports unblock requests, so in preparation for adopting its API, this patch allows
        content filters to specify their own unblock request method, teaches MockContentFilter to provide such a method,
        and writes tests to cover both allowed and denied unblock requests.

        The content filter that blocks a load creates a ContentFilterUnblockHandler, passing it a lambda that is executed
        when a navigation matches the filter's special unblock URL. Filters can also specify that a script be executed in
        the context of its error page if the unblock is denied.

        All platform content filters can handle unblock requests like this with the exception of iOS Parental Controls in WebKit2.
        Since UI can be displayed by the system in this case, the request must be made from within the UI process. Therefore the
        existing method is retained of serializing a WebFilterEvaluator and intercepting navigation policy calls in the UI process.

        Clean up DOMTimer related settings
        https://bugs.webkit.org/show_bug.cgi?id=142837

        Reviewed by Darin Adler.

        Clean up DOMTimer related settings:
        - Make default minimum timer interval 4ms instead of 10ms as all ports
          were setting it to 4ms and the specifications says 4ms.
        - Get rid of setters for default DOMTimer interval values as they are
          not set anymore.
        - Move default DOMTimer interval values from Settings to DOMTimer as
          those are global (not per-page) and not really settings.
        - Stop using abbreviations in the names (e.g. min -> minimum).
        - Move DOMTimer settings members from Page to Settings. There is no
          reason for those to be stored on the Page. The getters were private
          so call-sites had to go via Settings anyway. Also, call-sites already
          had to do a null check on the page to get the settings. It seems
          unfortunate for the settings to do another null-check on the page for
          retrieving the setting value from the page.
        - Inline the DOMTimer settings getters as these are trivial.

        FALLTHROUGH should not exist in unreachable code marked by

        When !ENABLE(CSS_SELECTOR_JIT) and Debug mode is enabled,
        both ASSERT_NOT_REACHED and FALLTHROUGH are instantiated

        Here, since CompiledSingle/CompiledSingleWithRootFilter are
        not set when !ENABLE(CSS_SELECTOR_JIT). So dropping FALLTHROUGH
        and leave ASSERT_NOT_REACHED.

        them have no intrinsic size, we do not updateInnerContentRect() and this
        means an SVGImageForContainer is not going to be created for this image.
        When the image is drawn, it is drawn directly from the SVGImage. And this
        means the drawing has to be scaled by container_size / SVG_default_intrinsic_size
        
        After figuring out that I need to updateInnerContentRect() to fix this bug,
        I found out Blink has already changed this code to do the same thing. But 
        they also did more clean-up in this function. Here is the link
        https://codereview.chromium.org/114323004. I think their change seems correct
        although they did not say what exactly they were trying to fix.
        
        The plan for repaintOrMarkForLayout(), which is the new name of this function,
        is the following:
            -- setNeedLayout() if the intrinsic size changes and it affects the size
               of the image.
            -- updateInnerContentRect() if the intrinsic size did not change but the
               image has exiting layout.
            -- repaint the image rectangle if layout is not needed.
            
        This change also removes the call to computeLogicalWidthInRegion(), which is
        almost running a layout for the image. This call figures out whether the image
        needs to setNeedsLayout(). This call is unnecessary; the image needs to run a
        layout if the intrinsic size has changed and it affects the size of the image.

        [Mac][iOS] setSharedTimerFireInterval() / stopSharedTimer() are expensive
        https://bugs.webkit.org/show_bug.cgi?id=142752
        <rdar://problem/20176731>

        Reviewed by Antti Koivisto.

        setSharedTimerFireInterval() / stopSharedTimer() are expensive on Mac
        and iOS on pages using a lot of timers.

        For example, on bing.com / iOS, ~15.4% of the CPU time is spent in
        setSharedTimerFireInterval() and ~14.7% of the CPU time is spent in
        stopSharedTimer(). The expensive calls are CFRunLoopAddTimer (11.4%),
        CFRunLoopTimerInvalidate (14.1%), CFRunLoopTimerCreate (3.3%).

        The issue is that we keep creating, adding to run loop modes, and then
        destroying the sharedTimer for each firing event. This is very
        expensive. In such case, the CFRunLoopTimerRef documentation advises to
        """
        ... create a repeating timer with an initial firing time in the distant
        future (or the initial firing time) and a very large repeat interval—on
        the order of decades or more—and add it to all the necessary run loop
        modes. Then, when you know when the timer should fire next, you reset
        the firing time with CFRunLoopTimerSetNextFireDate, perhaps from the
        timer’s own callback function. This technique effectively produces a
        reusable, asynchronous timer.

        Compile character ranges targeting the same state as range check in the bytecode
        https://bugs.webkit.org/show_bug.cgi?id=142759

        Reviewed by Alex Christensen.

        Previously, character ranges would be compiled as many individual character checks.
        For example, a transition on "[a-z]" would do 26 character checks + jump, which leads
        to enormous matchines.

        With this patch, we find the ranges at lowering time and generate a single instruction
        for them: "CheckValueRange". This helps making the machine denser when the input
        use character sets.

        The second part of this patch goes further in the case where the transitions out of
        a state cover the entire alphabet. In that case, we create a fallback transition
        on the fly and remove all the ranges made useless.
        That case is common when ranges are used with inverse character set (e.g. [^a]+a).

        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.

        DisplayRefreshMonitor that is created.

        If ChromeClient was unreachable for some reason, we'll get back an engaged
        nullptr and return it (instead of creating a DisplayRefreshMonitor based
        on the platform). This avoids creating the wrong type of DisplayRefreshMonitor
        in the rare case where we can't reach the ChromeClient (e.g. a freshly unparented
        IFrame).

        If instead the client returns a disengaged Nullopt, we'll interpret that as

        The debug overlays need to be updated after layout, in case elements with wheel event handlers
        moved around.
        
        DebugPageOverlays::didLayout() is cheap if there are no overlays.
        
        Call DebugPageOverlays::didLayout() for all frames, not just the main frame, since subframes can contribute

        Parsing and Style Resolution of Container-based Animation Triggers

        Take 2 after the previous patch was rolled out.

        This is the beginning of a prototype implementation of
        CSS Animation Triggers, as described by
        https://lists.w3.org/Archives/Public/www-style/2014Sep/0135.html

        In this patch we parse and resolve the value of a new
        CSS property "-webkit-animation-trigger". At the moment it
        only accepts one function value "container-scroll", which
        will trigger the animation at an absolute position within
        an element's scrolling container. We expect the syntax to
        change in the near future, as the spec is written.

        Make DatabaseContext suspendable if there is no pending database
        activity, i.e:
        - No pending Database creation JS callback
        - No pending transaction(s)

        Suspending is safe in this case because we are not going to interrupt
        any database activity, nor fire any JS event.

        This greatly increases the likelihood of pages using websql to enter
        the PageCache.

        Allow clients to selectively disable plug-ins
        https://bugs.webkit.org/show_bug.cgi?id=142506

        Reviewed by Anders Carlsson.

        Add new functionality allow clients to declaratively disable individual plug-ins (in a manner that conceals them
        from the page). As part of this:

        1) Introduce the concept of web-visible plug-ins and related concepts, as distinct from the real underlying
           set of plug-ins.

        2) Where applicable, plumb additional information about plug-ins (specifically, bundle identification) deeper
           down the stack.

        3) Add generic functionality to PluginStrategy to support filtering plug-ins for visibility and introduce
           a concrete implementation thereof in WebPlatformStrategies in WebKit2.

        4) Add messaging infrastructure to allow clients to set and clear plug-in policies.

        While currently only used in a very limited manner, the new declarative plug-in policies are written generically
        so that they could be easily used in the future to reduce synchronous messaging to the client when loading plug-ins.

        Scroll snap points are not supported on iframe content
        https://bugs.webkit.org/show_bug.cgi?id=142582
        <rdar://problem/20121319>

        Tested by css3/scroll-snap/scroll-snap-iframe.html

        Reviewed by Simon Fraser.

        The scroll snap points were not being applied to the iframe contents because the code
        that sets up the scroll snap point content is not called for iframes.

        To correct this, we need to make sure the snap offsets are set during post-frame layout

        Reduce the side-effects of animations turning off overlap testing
        https://bugs.webkit.org/show_bug.cgi?id=92791

        Reviewed by Dean Jackson.
        
        When a layer is running a transition or animation of the transform property,
        we would simply disable overlap testing for later layers, which had the side-effect
        of promoting lots of unrelated elements into layers temporarily.
        
        Fix by maintaining overlap, but computing an overlap extent that takes the animation
        into account.
        
        Rotations are currently treated as full rotations. If an extent for the overlap is
        hard to compute (e.g. 3d transforms, or matrix animations with a rotation component),
        then we fall back to the current behavior.

        If this layer is running a transform animation, set the childState.ancestorHasTransformAnimation flag so
        that descendants will know (nested transform animations fall back to current behavior).
        The if (.... && isRunningAcceleratedTransformAnimation()) is what previously caused us to turn off overlap
        testing in the face of animations. That now only happens if we were unable to easily compute the animation bounds.
        (WebCore::RenderLayerCompositor::isRunningTransformAnimation): This previously tested whether an accelerated animation
        was running, but that's timing sensitive; AnimationController can start the transform animation, but it's not yet
        considered accelerated until we get an async callback from GraphicsLayer, yet this code needed to know if the
        animation was running.
        Since transform animations are always accelerated, we can just test for a running transform animation.

        More event handler improvements
        https://bugs.webkit.org/show_bug.cgi?id=142701

        Reviewed by Anders Carlsson.

        These are the improvements:

        - Use EventHandler rather than EventListener as the the type for event handler
          attributes. This matches the HTML specification, and also makes sense, since
          EventListener means something else (and we use it to mean that!). Also renamed
          JSWindowEventListener to WindowEventHandler. Even though this only affects the
          JavaScript code generated, it's not really a JavaScript-specific flag.

        - Tweak formatting on addEventListener/removeEventListener/dispatchEvent in
          all the IDL files where the appear. This includes changing the spelling from
          "evt" to "event". Some day we should fix this so these functions only need to
          appear in EventTarget.idl.

        - Tweak formatting a bit on the IDL files we had to modify anyway.

        - Use [Conditional] more often and #if less often in IDL files.

        - Added a new [DocumentEventHandler] attribute for the selectionchange event.
          This involved adding new event handler attribute functions to JSEventListener.h
          for use by the JavaScript bindings.

        - Removed a little unused code from the JavaScript code bindings generator.

        - Improved the mechanism used by HTMLElement and SVGElement to share the list of
          content attributes that are event handlers so there is only one map rather than
          two. Made a similar mechanism so that HTMLBodyElement and HTMLFrameSetElement
          can share the list of window event handlers.

        - Followed the HTML specification by putting all the event handler support in
          the HTMLElement class rather than having event handlers apply only a the
          particular element that uses those events. We already did this for most of
          our event handlers, but we are now doing it for all of them.

        * Modules/battery/BatteryManager.idl: Use EventHandler instead of EventListener

        out of this. More closely matches the terminology used in IDL files and the
        HTML specification.

        of type "EventListener".
        * bindings/scripts/CodeGeneratorObjC.pm:

        * bindings/scripts/CodeGeneratorJS.pm:
        (GenerateImplementation): Look for the type EventHandler instead of the type
        EventListener for event handler attributes. Also added code to handle the new
        DocumentEventHandler, and use the name WindowEventHandler instead of the name
        JSWindowEventListener. Removed unneeded preflight check to see if we have
        writable attributes; it was not doing us any good. (That caused a lot of code
        to be un-indented and makes the diff hard to read.)

        * bindings/scripts/IDLAttributes.txt: Removed JSWindowEventListener, and added
        WindowEventHandler and DocumentEventHandler.

        * bindings/scripts/test/TestObj.idl: Use the type EventHandler instead of the
        type EventListener. The test output is unchanged, though.

        * dom/Document.idl: Got rid of the conditionals and merged all the event handler
        attributes into a single sorted, unconditional list. Added some that were missing,
        as detected by the event-handler-attributes.html test.

        * dom/Element.idl: Ditto. This includes moving attributes here that were formerly
        only in certain element classes. Note that the script event handler attribute
        support is still here, even though it should be in HTMLElement and SVGElement
        instead. There's a FIXME about that, but no real urgency in fixing it.

        * html/HTMLAttributeNames.in: Added onmessage. Previously, the support for this
        was from the script attribute only, not the content attribute.

        * html/HTMLBodyElement.cpp:
        (WebCore::HTMLBodyElement::createWindowEventHandlerNameMap): Added. This
        contains the list of all the window event handlers that can be set on a body
        or frameset element and which are triggered by events on the window.
        (WebCore::HTMLBodyElement::eventNameForWindowEventHandlerAttribute): Added.
        This is the function to call to use the map above. Given an attribute, it
        returns either null if it is not a window event handler attribute, or the
        event type if it is one.
        (WebCore::HTMLBodyElement::parseAttribute): Updated to use the new
        functions above. Handling of these attributes is now unconditional, but
        also we don't have to keep the nested if statements here up to date, just
        the list of event handler attributes names in the map create function above.

        * html/HTMLBodyElement.h: Added public eventNameForWindowEventHandlerAttribute
        and private createWindowEventHandlerNameMap functions.

        * html/HTMLBodyElement.idl: Updated to use WindowEventHandler, DocumentEventHandler,
        and EventHandler. Also made everything unconditional. Also filled out the list here
        to match the list handled as content attributes. All covered by the test.

        * html/HTMLElement.cpp:
        (WebCore::HTMLElement::createEventHandlerNameMap): Added. Replaces the old
        populate function. Changed the list of event handler attributes to be a bit more
        complete, and to be entirely unconditional. Also refactored this function to use
        a new populateEventHandlerNameMap helper, shared with HTMLBodyElement.
        (WebCore::HTMLElement::populateEventHandlerNameMap): Added. Factors out the code
        that both this class and HTMLBodyElement use to build event handler name maps.
        (WebCore::HTMLElement::eventNameForEventHandlerAttribute): Added. This is the
        function that call to use the map above. Given an attribute it returns either
        null if it is not an event handler attribute, or the event type if it is one.
        This is actually two functions. One is a protected function for use by both this
        class and HTMLBodyElement so they can share things like the optimization to look
        for the "on" prefix. The other is the public function that we actually use in
        HTMLElement and SVGElement.
        (WebCore::HTMLElement::editabilityFromContentEditableAttr): Tweaked and refactored
        to use lineageOfType. Would have been even simpler if this took an element instead
        of a node. Unrelated to the event handler changes.
        (WebCore::HTMLElement::parseAttribute): Removed long-obsolete code that decided
        whether to call through to the base class. The base class function is empty and
        never needs to be called, and in any case there is no value in doing work to
        decide whether to call through to an empty function. Changed the style of the
        function to use early return instead of else. Worth considering whether we want
        to return early or call through to base class in this family of functions. It's
        more efficient to return early, but doesn't work well if both the derived class
        and base class want to respond to changes to the same attribute. The new logic
        for event handler attributes is more straightforward than the old, since the
        eventNameForEventHandlerAttribute has the logic.
        (WebCore::HTMLElement::textToFragment): Tweaked and refactored a bit, and also
        changed to return a Ref since this never fails and needs to return null.

        * html/HTMLElement.h: Updated for above changes. This includes a template version
        of populateEventHandlerNameMap that extracts the array size at compile time and
        passes it to the non-template function that does the work.

        * html/HTMLFrameElementBase.cpp:
        (WebCore::HTMLFrameElementBase::parseAttribute): Removed unneeded code to handle
        event handler attributes handled by HTMLElement.
        * html/HTMLImageElement.cpp:
        (WebCore::HTMLImageElement::parseAttribute): Ditto.
        * html/HTMLLinkElement.cpp:
        (WebCore::HTMLLinkElement::parseAttribute): Ditto.
        * html/HTMLObjectElement.cpp:
        (WebCore::HTMLObjectElement::parseAttribute): Ditto.
        * html/HTMLScriptElement.cpp:
        (WebCore::HTMLScriptElement::parseAttribute): Ditto.

        * html/HTMLFrameSetElement.cpp:
        (WebCore::HTMLFrameSetElement::parseAttribute): Changed function to early return
        style, and added FIXMEs about the many problems in the attribute handling code.
        Replaced all the code to handle window event handlers with a new bit of code that
        calls HTMLBodyElement::eventNameForWindowEventHandlerAttribute.

        * html/HTMLFrameSetElement.idl: Changed to match the list of window event handlers
        in HTMLBodyElement.idl, although I did not add the document event handler here.
        As in the various other cases, having some extra event handlers does not seem to
        do harm and this is covered by the event-handler-attributes.html test.

        * html/HTMLMarqueeElement.idl: Renamed EventListener to EventHandler in comment.

        * page/DOMWindow.idl: As with Element and Document, removed conditionals, and
        filled out the list of event handlers so all the tests in
        event-handler-attributes.html will pass.

        * svg/SVGElement.cpp:
        (WebCore::SVGElement::parseAttribute): Changed code to the early return style,
        and replaced the event handler attribute code with new much simpler code that
        uses the new HTMLElement::eventNameForEventHandlerAttribute. Also changed the
        way we call through to base classes. Just call through to the
        SVGLangSpace::parseAttribute function unconditionally, and don't try to use
        early return style to arbitrate among base classes. We should make this
        simplification throughout the SVG code; there's no need for the complexity
        that was there before just to cut down slightly on calls through to base
        class parseAttribute functions.

        * svg/SVGSVGElement.cpp:
        (WebCore::SVGSVGElement::parseAttribute): Changed some of this code to the
        early return style and corrected some comments about the window event handler
        attributes here. These could use some further testing and might later need to be
        properly supported when the attributes are set in script, not just in content.

        * svg/SVGScriptElement.cpp:
        (WebCore::SVGScriptElement::isSupportedAttribute): Deleted.
        (WebCore::SVGScriptElement::parseAttribute): Changed this function to use the
        early return style and also to call through to all three base classes. This is
        a pattern we should follow elsewhere in SVG to simplify the code. There is no
        need for the supportedAttributes sets like the one in this calass, and the code
        is unnecessarily complex, perhaps in an attempt to optimize performance. I'm
        pretty sure the old code was slower than this new code will be. No need for the
        extra hash table lookup every time. Also removed handling of event handler
        attribute which is taken care of by SVGElement now.
        (WebCore::SVGScriptElement::svgAttributeChanged): Made similar changes for
        the same reason as in parseAttribute. This function really needs a new name:
        It's the same as parseAttribute, except it's also used when implementing
        changes due to SVG animation.

        * svg/SVGScriptElement.h: Removed isSupportedAttribute.

        Clean up use of flags in localToContainer-type functions

        Reviewed by Alexey Proskuryakov.
        
        RenderObject::localToContainerQuad() had the questionable behavior of always
        enforcing UseTransforms in the flags. However, a future patch will need to call
        localToContainerQuad() without this flag.
        
        Fix by requiring callers of localToAbsoluteQuad(), localToContainerQuad(), localToContainerPoint(),
        and absoluteToLocalQuad() to pass the UseTransforms flag in, providing it as a default argument.
        
        The default value of the MapCoordinatesFlags parameter to mapLocalToContainer(),
        a lower-level function, is removed.

        GstGL elements in a pipeline need to be aware of the application's

        This patch shares this context through a GStreamer's synchronous

        This patch is based on the work of Philippe Normand for Bug 138562.

        AX: Provide API for assistive tech to ignore DOM key event handlers
        https://bugs.webkit.org/show_bug.cgi?id=142059

        Reviewed by Beth Dakin.

        Assistive technology applications on the desktop are heavily dependent on keyboard navigation being reliable. This is greatly hindered by sites that handle key events without updating keyboard selection and then consume the event. It is important for assistive technology apps to allow users to decide to ignore these handlers that are incorrect for their purposes.

        This can be fixed by exposing, via a new accessibility attribute, a way to decide, for a given WebCore::Frame, to pre-empt DOM dispatch and instead let accessibility caret browsing take place.

        Allow clients to selectively disable plug-ins

        Reviewed by Anders Carlsson.

        Add new functionality allow clients to declaratively disable individual plug-ins (in a manner that conceals them
        from the page). As part of this:

        1) Introduce the concept of web-visible plug-ins and related concepts, as distinct from the real underlying
           set of plug-ins.

        2) Where applicable, plumb additional information about plug-ins (specifically, bundle identification) deeper
           down the stack.

        3) Add generic functionality to PluginStrategy to support filtering plug-ins for visibility and introduce
           a concrete implementation thereof in WebPlatformStrategies in WebKit2.

        4) Add messaging infrastructure to allow clients to set and clear plug-in policies.

        While currently only used in a very limited manner, the new declarative plug-in policies are written generically
        so that they could be easily used in the future to reduce synchronous messaging to the client when loading plug-ins.

        XMLHttpRequests should not prevent a page from entering PageCache
        https://bugs.webkit.org/show_bug.cgi?id=142612
        <rdar://problem/19923085>

        Reviewed by Alexey Proskuryakov.

        Make XMLHttpRequest ActiveDOMObjects suspendable in most cases to
        drastically improve the likelihood of pages using them to enter
        PageCache. XMLHttpRequest used to be only suspendable when not
        loading. After this patch, if the XMLHttpRequest is loading when
        navigating away from the page, it will be aborted and the page
        will enter the PageCache. Upon restoring the page from PageCache,
        the XMLHttpRequests' error handlers will be executed to give them
        a chance to reload if they want to.

        assertion does not seem to be hit by our current layout tests. I am

        Reviewed by Darin Adler.

        The bug was caused by TypingCommand::deleteKeyPressed erroneously determining the editable root to be empty because
        Position::atStartOfTree returns true when it's anchored at a BR that is immediately below the root editable element.

        Fixed the bug by replacing the use of the deprecated atFirstEditingPositionForNode by a code that understands modern
        position types such as PositionIsBeforeAnchor in atStartOfTree and atEndOfTree. These two functions will no longer
        return true when anchored before or after BR after this patch.

        <attachment> shouldn't use "user-select: all"

        It turns out that "user-select: all" is rife with bugs; in lieu of fixing them
        all (at least for now), let's not use "user-select: all" in the default stylesheet
        for <attachment>. It's really overkill anyway, since <attachment> can't have children.
        The only "user-select: all" behavior we actually want is select-on-click.
        So, we'll implement that in a slightly different way.

        Add basic support for BOL and EOL assertions to the URL Filter parser
        https://bugs.webkit.org/show_bug.cgi?id=142568

        Reviewed by Alex Christensen.

        This patch adds heavily restricted support for BOL and EOL to the URL filter parser.

        Both assertions must be the first/last term of their pattern. Any advanced combination
        results in a parsing error.

        The BOL assertion is easy to represent: currently, any pattern starts at the beginning
        of a line and the NFA are generated accordingly.

        I had two options to represent the EOL assertion:
        1) Add a new special transition on EOL.
        2) Add a new vector of actions to the states, conditional to the EOL input.

        I picked the first option to avoid growing every state by a vector
        that would be empty in the vast majority of cases.


        On the matching side, the interpreter was modified to support transitions on '\0'.
        DFABytecodeInstruction::CheckValue now stops when running on a character after
        the end of the string.

        DFABytecodeInstruction::Jump gets two fixes: First we now account for the index
        to avoid going past the end of the input. Second, stop on '\0' too... the reason
        is that the unconditional jump is only used for fallback edges of the DFA, fallback
        edge are not supposed to accept '\0'.

        (GenerateConditionalStringFromAttributeValue): Improved the algorithm here to
        handle combinations of & and | in conditional expressions; that's coming up when
        combining conditionals for includes in NavigatorContentUtils.idl.

        * bindings/scripts/CodeGeneratorJS.pm:
        (AddToImplIncludes): Removed the rudimentary attempt to split and merge
        conditionals involving | here; instead we rely on the rules in the
        GenerateConditionalStringFromAttributeValue to handle this.
        (GenerateImplementation): Passed new "conditional" argument to JSValueToNative.
        (GenerateParametersCheck): Pass "conditional" argument to AddToImplIncludes and
        JSValueToNative.
        (JSValueToNative): Changed to take "conditional" as an argument, since getting
        it from the signature won't work for a method parameter.
        (WriteData): Merge duplicates based on the result of the
        GenerateConditionalStringFromAttributeValue function rather than on the values
        passed into that function, since that function converts conditionals into a
        canonical form and can make two strings equal that don't start out that way.

        * bindings/scripts/CodeGeneratorObjC.pm:
        (SkipAttribute): Added code to guarantee we won't make Objective-C bindings

        (WebCore::HTMLMediaElement::didAddUserAgentShadowRoot): Added clearException.
        I noticed this was missing because a flawed earlier version of my patch was

        * html/HTMLVideoElement.idl: Moved event handler to Element.idl and use
        Conditional instead of #if.

        * page/DOMWindow.idl: Use Conditional instead of #if and tidy up the event

        CSS scroll-snap-destination and scroll-snap-coordinate are not honoring position values

        Reviewed by Simon Fraser.

        Revise the CSSParser to recognize that scroll-snap-coordinates and scroll-snap-destination

        and 'left', 'right', and 'center' for the X axis.

        Correct implementation to support calculated values for Scroll Snap Point markup. This required the
        Scroll Snap Point-specific LengthRepeat class to change its internal representation from a CSSPrimitiveValue
        to a regular CSSValue.

        Extend URL filter's Term definition to support groups/subpatterns
        https://bugs.webkit.org/show_bug.cgi?id=142519

        Reviewed by Alex Christensen.

        Pretty simple extension: Term is extended to support holding
        a Vector of Term. The quantifier of the Term applies to its
        Vector of term as a whole.

        To avoid exposing too much internal in the API of Term, I moved
        graph generation from GraphBuilder to Term.

        Sinking a CharacterSet works as usual. Sinking a Group is done
        by sinking each of its Terms one by one and then apply the quantifier
        on the whole subgraph. This is done by recursively calling into
        Term::generateGraph().

        Since groups could be nested, the groups make a stack with the latest
        open group on top.
        When sinking a floating Term, it is sunk to the latest open group. If there is no open
        group, we use the prefix tree and sink the whole subpattern to the graph.

        REGRESSION(r176978): Inline-blocks with overflowing contents have ascents that are too large
        https://bugs.webkit.org/show_bug.cgi?id=141783

        Reviewed by David Hyatt.

        When we have an inline-block element, and we want to find its baseline (to lay out other
        elements on the same line) we loop through the element's children and ask them what their
        baselines are. The children use the location of the top of their last line to compute this
        value. However, if the child has overflow-y, this might not be the correct calculation.

        This behavior is in the spec: "The baseline of an 'inline-block' is the baseline of its last
        line box in the normal flow, unless it has either no in-flow line boxes or if its 'overflow'
        property has a computed value other than 'visible', in which case the baseline is the bottom
        margin edge."
            -- http://www.w3.org/TR/CSS21/visudet.html#leading

        However, we believe that a better policy is, when overflow is not "visible," to place the
        baseline at the bottom of the block if the contents overflowed in the Y direction, and to place
        it at the bottom of the last line if the contents did not overflow in the Y direction. This is
        partially consistent with previous behavior, and isn't too far from the spec to cause too many
        breakages.

        The pseudo class :first-child has weaker tree marking than :nth-child(1).
        This patch aliases :nth-child(1) to :first-child in the CSS JIT to take
        advantage of that.

        The strength of :last-child and :nth-last-child(1) are pretty much identical
        but :last-child is a bit simpler so I changed it too. It is also easier
        to handle both the same.

        Merge TrivialAtom and CharacterSet into a Term abstraction, prepare Term for composition
        https://bugs.webkit.org/show_bug.cgi?id=142429

        Reviewed by Darin Adler.

        This patch merges CharacterSet and Trivial atom into a new class: Term. A Term is
        a combination of an Atom and one Quantifier.

        With term being the basic block, we can use the PrefixTree for any construct,
        greatly reducing the size of the NFA graph.

        Term is built on top of an union holding the Atom storage. This is done in preparation
        for more complicated Atoms like a disjunction.

        Everything else is pretty much the same. BuildMode is gone since we use the prefix
        tree for everything. FloatingAtomType is gone, a TrivialAtom is now represented
        by a single character CharacterSet (or two for case insensitive).

        A use-after-free would sometimes cause us to crash in NotificationCenter::stop().
        After investigation, it turns out that NotificationCenter::stop() calls
        NotificationClient::clearNotifications() which will destroy the Notification
        objects, all of which hold a strong reference to the NotificationCenter. If at
        this point, only Notifications are ref'ing the NotificationCenter, this means
        that the NotificationCenter will get destroyed right after the call to
        NotificationClient::clearNotifications(). However, we reset m_client to null
        after calling clearNotifications() and it causes us to crash in this case.

        The issue is addressed by adding a Ref<NotificationCenter> protector in
        NotificationCenter::stop() so that we make sure the NotificationCenter lives
        at least until the end of the method execution.

        I was able to consistently reproduce the crash by doing:

        Do a bit of EventNames tidying
        https://bugs.webkit.org/show_bug.cgi?id=142438

        Reviewed by Anders Carlsson.

        * dom/EventNames.h: Sorted the event names into a single list instead of
        the rudimentary attempts at organizing the list that simply made it hard
        to see what is and is not in the list. Removed two unused event names.
        I'm sure there are more. Reorganized the EventName class, now a struct,
        into a more conventional "public first" order. Got the function bodies
        out of the struct so we can see more clearly what is in the struct.
        Made more things const.
        (WebCore::EventNames::touchEventNames): Changed the return value to a
        std::array of reference wrappers rather than a vector of atomic strings.
        This should eliminate unnecessary memory allocation and reference count churn.

        * dom/EventNames.cpp: Changed initialization based on the above.

        * dom/EventTarget.cpp:
        (WebCore::EventTarget::getEventListeners): Use NeverDestroyed instead of
        DEPRECATED_DEFINE_LOCAL and also just tightened up the function a bit.

        * dom/Node.cpp:
        (WebCore::Node::didMoveToNewDocument): Streamlined this function with
        modern for loops, auto, and also tried to make what it does a bit clearer,
        by making loops that are just based on numbers of event listeners look a
        bit less like code that actually iterates a vector of listeners. Also used
        the type unsigned instead of size_t.

        * platform/ThreadGlobalData.h: Updated since it's a struct instead of class now.
        (Why is this file in platform!?)

        Allow composited clip-path to be updated without a layer repaint

        Reviewed by Zalan Bujtas.
        
        When clip-path is mapped to a compositing shape layer mask, we can just
        push a new shape to the GraphicsLayer to update the clip path, without
        needing to repaint.
        
        Achieve this by adding ContextSensitivePropertyClipPath. When set, and the
        stars are aligned, issue a StyleDifferenceRecompositeLayer rather than
        a StyleDifferenceRepaint.
        
        We ask RenderLayerCompositor whether the clip path can be composited

        https://bugs.webkit.org/show_bug.cgi?id=142379

        Reviewed by Zalan Bujtas.

        There are various tree dumping functions that are useful for debugging, and sometimes
        you want to be able to use them in release builds. Currently they are surrounded by
        #ifndef NDEBUG. Change this to #if ENABLE(TREE_DEBUGGING), which is defined to 0 or 1
        in config.h

        [Mac] 'Gliding' phase of scroll snap points is incorrect on desktop
        https://bugs.webkit.org/show_bug.cgi?id=142351
        <rdar://problem/20058023>

        Reviewed by Dean Jackson.

        This problem was caused by incorrectly starting a new snapping animation timer when the
        "end momentum" phase event had been received. This caused WebKit to recalculate the
        animation curve for the remaining distance, resulting in the bad animation behavior.

        Removing this incorrect start animation command when entering the momentum ended state
        resolves the problem.

        Document::recalcStyle() shouldn't call viewportContentsChanged() if there is a pending layout
        https://bugs.webkit.org/show_bug.cgi?id=142140

        Reviewed by Darin Adler.

        Stop calling FrameView::viewportContentsChanged() in Document::recalcStyle()
        if there is a layout pending to avoid doing unncessary work. If there is a
        layout pending, we don't need to do anything because viewportContentsChanged()
        will be called after layout.

        We only need to call FrameView::viewportContentsChanged() in
        Document::recalcStyle() if a style recalc does not cause a layout. For e.g.
        a '-webkit-transform' could make an animated GIF visible without causing a
        layout, in which case we need to resume the animated GIF after style recalc.

        Add basic support for character sets to the URL Filter parser
        https://bugs.webkit.org/show_bug.cgi?id=142257

        Reviewed by Alex Christensen.

        This patch is a first step toward making the URL filter parser a bit
        more powerful: it adds support for character set atom.

        I did not attempt to integrate that into the prefix tree in this patch,
        instead, the GraphBuilder gets a two modes of generating the NFA:
        PrefixTree and DirectGeneration.

        As long as we only see trivial atoms, we use the PrefixTree generation
        to minimize the number of nodes we need. As soon as we start a character
        class, we switch to DirectGeneration and we generate the NFA from the input
        without merging with previously seen patterns.

        To differentiate between Trivial atoms and CharacterSet, we also gain
        an AtomType state.

        The character set themself are very simple: each character is represented by
        a bit in a 16bytes bit vector.

        Make RenderElement::adjustStyleDifference() clearer in two ways.
        
        First, replace lots of if (diff < X) diff = X with
        diff = std::max(diff, X). I did this even in cases where diff was
        being set unconditionally, because it's never correct to change the diff
        to a lesser value.
        
        Second the "set at least SimplifiedLayout, but if we have PositionedMovementOnly
        set it to SimplifiedLayoutAndPositionedMovement" was confusingly written.

        [Content Filtering] Make it easier to add new content filters
        https://bugs.webkit.org/show_bug.cgi?id=142255

        Reviewed by Sam Weinig.

        ContentFilter was becoming a bit of a mess, with both the WebFilterEvaluator and NEFilterSource implementations
        awkwardly living side-by-side. This patch cleans things up by moving these implementations into two separate
        classes and turning ContentFilter itself into an abstract interface that each implements. A new class called
        ContentFilterCollection, which also inherits from ContentFilter, manages the collection of individual content
        filters and is vended to the rest of the system by ContentFilter::createIfNeeded().

        This refactoring will make it easier to add a third type of content filter in a follow-on patch, namely a mock
        content filter for testing purposes.

        Implement -apple-trailing-word: -apple-partially-balanced
        https://bugs.webkit.org/show_bug.cgi?id=142253

        This patch implements a history mechanism for line breaking. In particular, this patch partitions
        the updates to the current line breaking location into two kinds: conceptually new breaking locations,
        and fixups to existing locations. Then, this patch remembers all the fixed up breaking locations, up
        to a maximum number of remembered locations.

        The patch then uses this memory to change the line-breaking selection based on the rules of
        -apple-trailing-word.

        [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.

        This patch adds a microtask abstraction: https://html.spec.whatwg.org/multipage/webappapis.html#microtask
        That abstraction is required in order to enable async loading of images,
        which is in turn required to enable support for the picture element, as well as
        to make sure that the order of properties set on HTMLImageElement has no implications.

        Avoid applying the clip-path when painting, if a layer also has a shape layer mask
        https://bugs.webkit.org/show_bug.cgi?id=142212

        Reviewed by Zalan Bujtas.

        After r180882 we translate clip-path into a composited shape mask when the layer
        is composited. However, we were also still applying the clip-path when painting

        Now, we set the GraphicsLayer bits GraphicsLayerPaintClipPath and GraphicsLayerPaintMask
        only for the m_maskLayer's painting. This translate into setting PaintLayerPaintingCompositingMaskPhase

        Make AudioContext suspendable when it is not rendering

        Make AudioContext suspendable when it is not rendering to increase the
        likelihood of entering the PageCache for pages using WebAudio.

        This patch adds a state member to AudioContext with 3 possible states:
        Suspended / Running / Closed, as defined in the specification:
        http://webaudio.github.io/web-audio-api/#widl-AudioContext-state

        This state is used to decide if we can suspend the page or not. We
        can safely suspend if the AudioContext's state is suspended (did not
        start rendering) or closed (Stopped rendering).

        Note that this patch does not expose the AudioContext's state to the
        Web yet, even though it is exposed in the latest specification.

        [SOUP] Synchronous XMLHttpRequests can time out when we reach the max connections limit
        https://bugs.webkit.org/show_bug.cgi?id=141508

        Reviewed by Sergio Villar Senin.

        Use SOUP_MESSAGE_IGNORE_CONNECTION_LIMITS flag when loading a
        synchronous message instead of increasing the maximum number of
        connections allowed if the soup version is recent enough.
        The current solution of increasing/decreasing the limits doesn't
        always work, because connections are not marked as IDLE in libsoup
        until the message is unqueued, but we don't wait for the message
        to be unqueued to finish our loads in WebKit, we finish them as
        soon as we have finished reading the stream. This causes that
        synchronous loads keep blocked in the nested main loop until the
        timeout of 10 seconds is fired and the load fails.
        Also marked WebCoreSynchronousLoader class as final, the virtual

        Make clip-path work on <video>, <canvas> etc.

        clip-path only worked in compositing layers on the painted contents of the layer,
        and failed to clip children. Fix this by translating the clip path into a Path
        which is set on a CA shape layer (for Mac and iOS), or painted into the
        RenderLayerBacking's mask layer. There are two code paths:

        1. clip-path which is a <basic-shape> or <geometry-box>, and no mask.
            Here we can use the optimal code path of converting the clip into a path
            that is put onto a CAShapeLayer, which is then used as a mask. There is no
            additional backing store.
        2. clip-path with an SVG reference, or clip-path combined with -webkit-mask:
            Here we have to allocate backing store for the mask layer, and paint the
            clip path (possibly with the mask).
        
        We add GraphicsLayer::Type::Shape, and add a getter for the layer type.

        If the style recalc timer has been scheduled to fire after the layout timer,

        newly extracted computeEditability in call sites that specify this option since isContentEditable
        is a public DOM API.

        Drop unnecessary DatabaseManager::hasOpenDatabases() in PageCache::canCachePageContainingThisFrame()

        Reviewed by Andreas Kling.

        Drop WebDatabase special-handling from PageCache::canCachePageContainingThisFrame().
        DatabaseContext is already an ActiveDOMObject and DatabaseContext::canSuspend() was
        returning false so pages using WebDatabase would never enter the PageCache anyway.

        This patch also overrides ActiveDOMObject::canSuspend() in DatabaseContext to only
        return false when there are open databases. This check is now equivalent to the one
        that was in PageCache.

        An issue that remains is that DatabaseContext::m_hasOpenDatabases is never reset
        to false so once a page opened a database, it will never be page-cacheable. This
        will be taken care of separately though.

        Use after free in WebCore::RenderNamedFlowFragment::restoreRegionObjectsOriginalStyle
        https://bugs.webkit.org/show_bug.cgi?id=138366

        Reviewed by Dave Hyatt.

        This patch ensures that we clean up RenderNamedFlowFragment::m_renderObjectRegionStyle when embedded flow content is getting destroyed.

        In m_renderObjectRegionStyle hash map, we store style information about the named flow's descendant children.
        When a child is being detached from the tree, it removes itself from this hashmap.
        We do it by traversing up on the ancestor chain and call removeFlowChildInfo() on the parent flow.
        However in case of embedded flows (for example multicolumn content inside a region), we need to check whether the parent flow
        is inside a flow too and continue the cleanup accordingly.

        Cache glyph widths to GlyphPages
        https://bugs.webkit.org/show_bug.cgi?id=142028

        Reviewed by Andreas Kling.

        Currently we have a separate cache in Font for glyph widths. In practice we always need
        the widths so we can just cache them in GlyphPages. This simplifies the code and removes

        isEditablePosition and related functions shouldn't move position out of table
        https://bugs.webkit.org/show_bug.cgi?id=129200

        Reviewed by Darin Adler.

        This patch removes the legacy editing position for elements display: table in its computed style.
        Previously, we used (table, 0) and (table, !0) to denote positions immediately before and after
        such an element for historical reasons. This forced us to update the style tree before computing
        the editability of a position because we have to check the editability of the position outside
        the element with display: table if the position was using such a legacy editing position.
        e.g. if a table was not editable (contenteditable=false), the position before the table (table, 0)
        should still be considered editable if the parent node of the table was editable.

        This patch replaces such a legacy editing position by using modern position types:
        PositionIsBeforeAnchor and PositionIsAfterAnchor.

        No new tests since there should be no change in the user perceived editing operations.

        * dom/Position.cpp:
        (WebCore::Position::previous): Setup the node and the offset correctly when the original position's
        type is PositionIsBeforeAnchor. Also return a position before or after node when the node we found
        is "atomic" (e.g. input, img, br, etc...) or it's a table. This avoids creating a legacy editing
        position inside a table.
        (WebCore::Position::next): Ditto.
        (WebCore::Position::atStartOfTree): Use atFirstEditingPositionForNode, which takes care of all types
        of positions.
        (WebCore::Position::atEndOfTree): Ditto.
        (WebCore::Position::downstream): Return a position before a node instead of a legacy editing position
        for an atomic element or a table element as done in the equivalent code in Position::upstream.
        (WebCore::Position::isCandidate): Don't treat a position inside a table to be a candidate. e.g.
        (table, 1) when there are more than two children of the table.

        * dom/PositionIterator.cpp:
        (WebCore::PositionIterator::operator Position): PositionIterator internally uses legacy editing
        positions. So convert it to a modern position by returning a position before or after a table here.
        * editing/ApplyBlockElementCommand.cpp:
        (WebCore::ApplyBlockElementCommand::formatSelection): Check that the unsplittable element we found
        is actually empty before executing the simple code path for an empty unsplittable element. Without
        this check, block formatting a table element will fail.

        * editing/htmlediting.cpp:
        (WebCore::isEditablePosition): Use containerNode instead of deprecatedNode because the editability
        of a position before or after an element is determined by its parent, not the element itself.
        (WebCore::isAtUnsplittableElement): Ditto.
        (WebCore::isRichlyEditablePosition): Ditto. Removed the code that moved the starting node out of
        an element with display: table. This is the code removal for which this patch was made.
        (WebCore::editableRootForPosition): Ditto.

        Reviewed by Chris Fleizach.

        Exposing the caret browsing setting on WebCore::Frame via the accessibility API would allow assistive tech apps to enable it contextually (for example, when the assistive tech app is running).
        Enabling caret browsing when assistive tech apps are running greatly improves the reliability of keyboard navigation on the web. Most especially in cases where selection would be disrupted by focus events.

        Not reviewed.

        The r180602 solution does result in more work for GC when worker
        threads are in use.  Filip is uncomfortable with that.
        The EFL and GTK ports also seem to be unhappy with this change.

        [Mac] [iOS] Parsing support for -apple-trailing-word
        https://bugs.webkit.org/show_bug.cgi?id=141939

        Reviewed by Andreas Kling.

        This patch implements initial parsing support for the -apple-trailing-word CSS property.
        This property has two possible (mutually exclusive) values: auto and
        -apple-partially-balanced. This property is inherited.

        The work for this property is behind the ENABLE(CSS_TRAILING_WORD) preprocessor define.

        This is an internal property that will allow us to control line breaking behavior for
        short paragraphs.

        Note that, because of the implementation of cssValueKeywordID() in CSSParser.cpp,
        the new value must be implemented as -webkit-partially-balanced. Using the -apple-
        prefix will work, but if you getComputedStyle(), it will return the -webkit- prefixed
        version.

        Reviewed by Chris Dumez.

        This bug has been here since r110484 but was uncovered by
        r180140. The problem r110484 was trying to fix was that
        CSSPrimitiveValue::convertToLength<Length> ended up calling
        CSSPrimitiveValue::computeLengthDouble() which was apparently
        dereferencing conversionData.style() and
        conversionData.rootStyle() pointers without checking them. That's
        why that fix added this condition to convertToLength():

        isFontRelativeLength() && (!conversionData.style() || !conversionData.rootStyle())

        which is not correct, because for the 4 possible font relative
        length types, 3 of them just use the style() pointer and the other
        one just uses rootStyle() which BTW could be NULL. This erroneous
        condition makes that function to return Length(Undefined) more
        often than it should.

        From now on it only returns Length(Undefined) if the style()
        pointer is NULL and the font relative length type is one in the

        Reviewed by Darin Adler.

        Our track sizing algorithm implementation incorrectly grew some
        tracks beyond limits when handling min-content and max-content
        base sizes. In those cases we should only grow "any affected track
        that happens to also have an intrinsic max track sizing function"
        or all of them if there are none.

        The problem was that we're using a vector of indexes pointing to
        the vector with the list of affected tracks. Those indexes become
        easily incorrect because the first thing we do in
        distributeSpaceToTracks() is to sort the vector with the affected
        tracks by growth potential.

        Instead of that we now pass a vector with pointers to the list of
        tracks allowed to grow over the limits. The size changes are now
        directly stored in the GridTracks (it's called plannedSize)
        instead of in a separate vector, so we don't need to worry about
        tracks being rearranged (and we also get rid of the ugly vector of
        indexes pointing to another vector).

        Clarify some resizing terminology in ScrollView/FrameView
        https://bugs.webkit.org/show_bug.cgi?id=141996

        Reviewed by Zalan Bujtas.

        ScrollableArea/ScrollView/FrameView had some confusing terminology around
        contentsResized/visibleContentsResized/fixedLayoutSizeChanged.
        
        Clarify this by distinguishing between:
        1. Available size changes because of
            i) non-overlay scrollbar presence
           ii) ScrollableArea frame change
        2. Removing fixedLayoutSizeChanged() and just treating it like an
           available size change.
           
        contentsResized() is relegated to simply being a hook that allows Mac to
        flash overlay scrollbars.
        
        The confusingly named visibleContentsResized() is now updateContentsSize(),
        and is the way that a ScrollableArea tells its subclasss that it should recompute
        the size of the contents (i.e. do a layout).

        * page/FrameView.cpp:
        (WebCore::FrameView::setContentsSize): No longer mysteriously skip the
        FrameView implementation of contentsResized(), which used to do a setNeedsLayout()
        which we didn't want to do from setContentsSize(), which itself happens as a result of layout.

        (WebCore::FrameView::layout): Ditto.

        will bail if not a forced update.

        replace with updateContentsSize().
        (WebCore::ScrollView::setFrameRect): Call availableContentSizeChanged() now. This takes care of
        updating scrollbars, so no need to explicitly do that.

        [Mac] [iOS] Parsing support for -apple-trailing-word
        https://bugs.webkit.org/show_bug.cgi?id=141939

        Reviewed by Andreas Kling.

        This patch implements initial parsing support for the -apple-trailing-word CSS property.
        This property has two possible (mutually exclusive) values: auto and
        -apple-partially-balanced. This property is inherited.

        The work for this property is behind the ENABLE(CSS_TRAILING_WORD) preprocessor define.

        This is an internal property that will allow us to control line breaking behavior for
        short paragraphs.

        Note that, because of the implementation of cssValueKeywordID() in CSSParser.cpp,
        the new value must be implemented as -webkit-partially-balanced. Using the -apple-
        prefix will work, but if you getComputedStyle(), it will return the -webkit- prefixed
        version.

        [GTK] Fonts loaded via @font-face look bad
        https://bugs.webkit.org/show_bug.cgi?id=140994

        Reviewed by Martin Robinson.

        We've had several complaints that woff fonts look bad on some websites. This seems to be a
        combination of multiple issues. For one, we don't look at Fontconfig settings at all when
        creating a web font. This commit changes FontPlatformData::initializeWithFontFace to instead
        use sane default settings from Fontconfig when loading a web font, rather than accepting the
        default settings from GTK+, which are normally overridden by Fontconfig when loading system
        fonts. However, we will hardcode the hinting setting for web fonts to always force use of
        the light autohinter, so that we do not use a font's native hints. This avoids compatibility
        issues when fonts with poor native hinting are only tested in browsers that do not use the
        native hints. It also allows us to sidestep future security vulnerabilities in FreeType's
        bytecode interpreter.

        The net result of this is that there should be little noticable difference if you have GTK+
        set to use slight hinting (which forces use of the autohinter) unless you have customized
        Fontconfig configuration, but a dramatic improvement with particular fonts if you use medium
        or full hinting. This should reduce complaints about our font rendering on "fancy sites."

        No new tests, since the affected fonts we've found are not freely redistributable.

        Reviewed by Antti Koivisto.

        The Cocoa implementation of Font::platformCreateScaledFont() tried to be smart and use the FontCache.
        This didn't work out well when scaling a 0pt Font, since scaling 0pt by any factor will return 0pt.

        We'd have a 0pt font, scale it by 0.7 to get a small-caps variant, and then cache that small-caps
        variant (really "this") in Font::m_derivedData->smallCaps.

        Fix this by having Cocoa Font scaling do exactly what other platforms do: create a new Font every time.
        This stops us from accumulating tons of abandoned Font objects over time.

        [Streams API] Reading ReadableStream ready and closed attributes should not always create a new promise
        https://bugs.webkit.org/show_bug.cgi?id=141650

        Reviewed by Benjamin Poulain.

        The JSPromiseDeferred objects returned by JSReadableStream::ready and JSReadableStream::closed should be stored somewhere.
        This patch stores them as private slots in JSReadableStream.
        This is close to the description in https://streams.spec.whatwg.org/#rs-internal-slots.

        An alternative would be to have these objects as JSReadableStream class members, thus modifying the binding generator.
        That may be the cleanest solution, especially if other APIs express the same need.
        Another alternative is to store DeferredWrapper in ReadableStream objects.
        But it is currently preferred to keep DeferredWrapper in bindings/js code.

        Added new constructor for DeferredWrapper to use these stored values.
        Updated ready and closed methods to use that new constructor.
        Changes are covered by new test in streams/readablestream-constructor.html.

        CSS JIT: add support for case-insensitive attribute matching
        https://bugs.webkit.org/show_bug.cgi?id=141880

        Reviewed by Andreas Kling.

        The value matching now has 3 cases:
        1) Case-sensitive.
        2) Case-insensitive.
        3) Legacy HTML Case-insensitive.

        The information to determine the case is split over 2 source:
        -To know if explicit case-insensitive is needed, we need to ask the selector
         for attributeValueMatchingIsCaseInsensitive().
        -To know if the legacy HTML behavior is needed, we need to test the attribute
         name filter with HTMLDocument::isCaseSensitiveAttribute().

        I decided to perform all those checks at the fragment creation step.
        This makes the register requirements and code generation more explicit.

        From there, everything is easy: switch() on the type of matching needed,
        and generate the code. The new case-insensitive case is a simplified version
        of the legacy HTML behavior without runtime check for the element type.

        Make namespace configurable for SOFT_LINK_*_{HEADER,SOURCE}() macros
        <http://webkit.org/b/141849>

        Reviewed by Brent Fulgham.

        This patch does the following:
        - Add namespace argument to the SOFT_LINK_*_{HEADER,SOURCE}()
          macros for reuse in other projects.
        - Adds SOFT_LINK_FRAMEWORK_SOURCE() macro in preparation for Bug
          141816.
        - Adds back framework argument to SOFT_LINK_FUNCTION_HEADER()
          and includes framework name in generated function names.  This
          adds more entropy to the names in case there are two functions
          with the same name in different frameworks.

        * platform/cf/CoreMediaSoftLink.cpp:

        [iOS] Fix inefficiencies in ResourceResponse::platformLazyInit()

        Reviewed by Alexey Proskuryakov.

        Fix inefficiencies in iOS's ResourceResponse::platformLazyInit()
        implementation, similarly to what was already done for Mac in:
        <http://trac.webkit.org/changeset/174717>

        The following changes were made:
        - Add missing "initLevel == AllFields" check before initializing
          uncommon fields. This bug was causing us to initialize uncommon
          fields even if called with 'CommonFieldsOnly' initLevel.
        - Bypass the first pass populating common HTTP headers in
          m_httpHeaderFields if the initLevel is AllFields. If called
          with AllFields initLevel, we will end up populating all HTTP
          headers later on so this first pass is redundant.
        - Use C++11 range loop to iterator over commonHeaderFields array
          for readability.
        - Use CFDictionaryApplyFunction() to populate m_httpHeaderFields
          for the CFDictionaryRef containing the headers instead of creating
          copies of keys and values using CFDictionaryGetKeysAndValues() and
          then iterating over those. This avoids allocating Vectors for keys /
          values and avoids unnecessary copying.

        Sufficiently small media controls should remove toolbar elements

        Reviewed by Eric Carlson.

        Implement some logic where elements on the media controls are
        hidden when there isn't enough room. We start by dropping
        the scrubber, then the various buttons on the right hand
        side.

        This solution isn't perfect. If we had perfection, it would
        be because we get resize events and respond accordingly. Instead
        we check the size when the user has pinch-zoomed, or when
        we start/stop playing.

        This is going to cause some extra layout, because we need
        to know the size of things before we can work out which
        bits to hide.

        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.

        Evict dead resources in MemoryCache in MemoryPressureHandler::releaseNoncriticalMemory()

        Reviewed by Andreas Kling.

        Evict dead resources from the MemoryCache on non-critical memory
        pressure. On critical memory pressure, we already evict ALL resources
        from the MemoryCache. It is a good idea to start by evicting resources
        we care less about on non-critical warning to decrease the chances of
        getting a critical warning and thus having to clear the whole
        MemoryCache.

        Call releaseCriticalMemory() before releaseNoncriticalMemory()
        as releaseCriticalMemory() is more aggressive. Doing it the
        other way around would mean that on critical warning, we would
        first evict dead resources, then evict all resources. It is
        more efficient to evict all resources first, as it makes the
        non-critical operation (evict dead resources) a no-op.

        This makes them behave a lot more like iOS 7.

        the relaxed restrictions (we still want to show the start button
        in that case).
        (ControllerIOS.prototype.showControls): When we show the controls,
        make sure our timeline is up to date. This is necessary for the

        Rework the DOMObjectCache to avoid having to manually clear the

        instead. When a new object associated to a Frame is added to the
        cache, a FrameDestructionObserver is created for the frame if
        needed, and the DOM object is tracked by the observer too. When
        the frame is detached from the page all its objects are cleared,
        and if the aren't additional references, the object is finalized
        and removed from the cache normally.

        CSS JIT: finish :nth-last-child()
        https://bugs.webkit.org/show_bug.cgi?id=141629

        Reviewed by Andreas Kling.

        This patch adds the matcher for :nth-child(An+B of selector list) and
        fix a small bug I discovered while working on it.

        The matcher is straightforward: count the next siblings matching the selector,
        nothing fancy.

        While working on it I noticed I forgot the test for IsParsingChildrenFinished
        on the simple version of :nth-last-child(). I add it in both matcher, write
        a couple of tests, the first part of the tests now succeed, but the second part
        fails...

        What happened is:
        1) We interupt the parsing to execute the JavaScript.
           From there, we force the style resolution to get the computed style.
        2) When resolving the style, the early check for isFinishedParsingChildren()
           quits the function early. This is done *before* we marked the parent
           for :nth-last-child() style resolution.
        3) After the script, parsing resume and the following elements are added.
        4) When resolving the style, only the new elements are marked dirty,
           the elements pending their :nth-last-child() style never get udpated.

        To fix the problem, I moved the test for FinishedParsingChildren after
        the parent marking.

        Honestly, those early return for FinishedParsingChildren need to be refined
        and they should be tested properly. We should not do this kind of things
        for Query for example.

        [CSS Grid Layout] Invalid initialization of track sizes with non spanning grid items
        https://bugs.webkit.org/show_bug.cgi?id=140763

        Reviewed by Antti Koivisto.

        Content sized tracks with non-spanning grid items were not
        properly sized because the growth limit was sometimes infinity
        (-1) after calling resolveContentBasedTrackSizingFunctions() when
        it should not. This patch adds an special initialization phase for
        non-spanning grid items as the new track sizing algorithm
        describes.

        Granted, that was handled in the old algorithm in
        distributeSpaceToTracks() as a special case. The problem is that
        it regressed after the optimization added in r173868 because that
        method is no longer called when the space to distribute is 0.

        That's why we could fix this by allowing calls to
        distributeSpaceToTracks() with spaceToDistribute>=0 but by fixing
        it with an explicit initialization our implementation becomes
        closer to the new algorithm and the initialization is now explicit
        in the code instead of a side effect of calling
        distributeSpaceToTracks() with no space to be distributed. It also
        brings a slight performance improvement as we save sorts and hash
        lookups.

        I also took the change to add caching to several GridTrackSize
        methods that were hot on the profiler (each one accounted for ~1%
        of the total time, now they account for ~0.3% each).

        Reviewed by Chris Dumez.

        From Blink r164154 by <timloh@chromium.org>

        The patch simplifies some of the logic in creating and applying
        GridLength and GridTrackSize values to RenderStyles by using the
        constructors for initialisation instead of deferring to setters.

        The rationale behind this change is that neither of
        createGridTrackSize() nor createGridTrackBreadth() should be able
        to fail, so these are changed to return objects directly instead
        of taking an out reference (note that in general failing in
        applying properties is incorrect and we should catch these in the
        parser).

        The quirk value across to the Lengths was also removed because it

        Removing text node does not remove its associated markers
        https://bugs.webkit.org/show_bug.cgi?id=140999

        Reviewed by Ryosuke Niwa.

        Removing text node via script does not remove its markers.
        For example, running the following script:

        <script>
            var div = document.getElementById("testElement");
            div.focus();
            document.execCommand("InsertText", false, "welllcome ");

            // Give a time async spellchecker to show its markers and
            // remove the node.
            setTimeout(function() { div.removeChild(div.firstChild); }, 100);
        </script>

        will cause that DocumentMarkerController still stores the markers for
        detached node.

        The same issue occurs when the text gets cleared, for example,
        <script>
            input.value = ""; // for HTMLTextAreaElement, HTMLInputElement
            // or
            div.innerHTML = ""; // for content editable
        </script>

        No new tests. Internals marker APIs operate on text node attached
        to the element. To test it we could expose document().markers().hasMarkers()
        but there is no more useful cases where it could be used.
        Another obstacle is that we are in isInShadowTree() so that there is
        no possible to register on "DOMSubtreeModified" event.

        REGRESSION (r180082): WebCore Debug builds fail on Mavericks due to weak export symbols
        <http://webkit.org/b/141607>

        This should fix the build, but leaves a FIXME list in
        WebCore.unexp.

        * Configurations/WebCore.unexp: Add weak externals with a FIXME
        statement so they can be removed later.  It's more important to
        fix the build first.

        * Configurations/WebCore.xcconfig: Change XCODE_VERSION_MINOR to
        XCODE_VERSION_MAJOR since the internal bots use version 5.1.1
        which still has the error.

        Do not unnecessarily update the marker's style in RenderListItem::styleDidChange()
        if the RenderStyle diff is StyleDifferenceEqual. Doing so can cause unnecessary
        layouts.

        This was causing high cpu usage on
        http://www.nokogiri.org/tutorials/searching_a_xml_html_document.html because there
        is an animation that changes the style every second (but the diff is equal) and the
        RenderListItem keeps resetting its marker's margin, which triggers a layout and the
        RenderListMarker re-computes its margin during layout and updates its style again.

        With this change, CPU usage on the page goes from 150% to 20%. There is only a style
        recalc happening every second, no more relayouts and repaints.

        It's possible for a layout to dirty the parent frame's state, via the calls to
        ownerElement()->scheduleSetNeedsStyleRecalc() that RenderLayerCompositor does when
        iframes toggle their compositing mode.
        
        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()

        When receiving a memory pressure warning, tell the garbage collector to
        accelerate its next collection (by calling garbageCollectSoon().)
        This gives us some confidence that a collection will happen within a
        reasonable timeframe, but doesn't risk dooming us to a loop of endless

        [CSS Grid Layout] Invalid initialization of track sizes with non spanning grid items
        https://bugs.webkit.org/show_bug.cgi?id=140763

        Reviewed by Antti Koivisto.

        Content sized tracks with non-spanning grid items were not
        properly sized because the growth limit was sometimes infinity
        (-1) after calling resolveContentBasedTrackSizingFunctions() when
        it should not. This patch adds an special initialization phase for
        non-spanning grid items as the new track sizing algorithm
        describes.

        Granted, that was handled in the old algorithm in
        distributeSpaceToTracks() as a special case. The problem is that
        it regressed after the optimization added in r173868 because that
        method is no longer called when the space to distribute is 0.

        That's why we could fix this by allowing calls to
        distributeSpaceToTracks() with spaceToDistribute>=0 but by fixing
        it with an explicit initialization our implementation becomes
        closer to the new algorithm and the initialization is now explicit
        in the code instead of a side effect of calling
        distributeSpaceToTracks() with no space to be distributed. It also
        brings a slight performance improvement as we save sorts and hash
        lookups.

        I also took the change to add caching to several GridTrackSize
        methods that were hot on the profiler (each one accounted for ~1%
        of the total time, now they account for ~0.3% each).

        Remove the USE(ACCELERATED_COMPOSITING) guard from the
        MediaPlayerPrivateGStreamerBase destructor.

        The guard was removed in r163079. It was still defined through CMake
        for the EFL and GTK ports when the guarded code was introduced in
        r172828. In r171741 the macro was finally removed for the GTK and EFL
        ports as well, but the guards for the affected code weren't updated
        so TextureMapperPlatformLayer::Client::platformLayerWillBeDestroyed()
        wasn't being called anymore.

        (WebCore::SVGUseElement::create): Removed the code that calls the
        ensureUserAgentShadowRoot function unconditionally. That's properly done when
        needed; no need to do it here.
        (WebCore::SVGUseElement::~SVGUseElement): Removed unneeded code to destroy the
        shadow tree (that happens automatically) and simplified the code to stop loading
        the external document.
        (WebCore::SVGUseElement::isSupportedAttribute): Deleted.
        (WebCore::SVGUseElement::parseAttribute): Simplified this. Removed assumptions
        about the intersection of various sets of attributes, and also removed the
        isSupportedAttribute function. This seems to serve no purpose here, or in any
        other SVG element class. I plan to remove it everywhere over time.
        (WebCore::isWellFormedDocument): Deleted.
        (WebCore::SVGUseElement::insertedInto): Simplified code by removing all the
        special cases during initial parsing, and did the invalidation here rather than
        deferring it to didNotifySubtreeInsertions. Added a call to the new function,
        updateExternalDocument, since that won't do anything when the element is not
        in a document.
        (WebCore::SVGUseElement::didNotifySubtreeInsertions): Deleted.
        (WebCore::SVGUseElement::removedFrom): Added code to call clearShadowTree and
        updateExternalDocument. Both are efficient when doing nothing, and both are
        appropriate since the element is no longer in a document.
        (WebCore::SVGUseElement::referencedDocument): Deleted. No longer needed.
        (WebCore::SVGUseElement::externalDocument): Streamlined the logic here, removing
        multiple unneeded checks.
        (WebCore::SVGUseElement::transferSizeAttributesToTargetClone): Renamed since
        "target clone" is clear enough within this class, without explicitly stating
        "shadow tree". All the clones are in the shadow tree.
        (WebCore::SVGUseElement::svgAttributeChanged): Removed unneeded code calling
        isSupportedAttribute. Changed the code that detects changes in href to just
        call updateExternalDocument (for the document URL) and invalidateShadowTree
        (for the fragment). Also updated the transferSizeAttributesToTargetClone logic
        to only trigger on width and height and updated names.
        (WebCore::SVGUseElement::willAttachRenderers): Updated for the new name of
        m_shouldRebuildShadowTree and added a call through to the base class.
        (WebCore::createAllowedElementSet): Added. A more efficient way to implement
        the initialization of the set for isDisallowedElement.
        (WebCore::isDisallowedElement): Simplified this by using the function above,
        and also overloaded for both SVGElement and Element for a tiny efficiency boost.
        (WebCore::SVGUseElement::clearShadowTree): Renamed form clearResourceReferences.
        This is a much more straightforward name. Also deleted the code that sets the
        m_needsShadowTreeRecreation flag to false. That should be done by the build
        function, not here.
        (WebCore::SVGUseElement::buildPendingResource): Made this just invalidate the
        shadow tree now instead of explicitly building it.
        (WebCore::SVGUseElement::updateShadowTree): Moved the code to create a shadow
        tree here from buildPendingResource. ALso changed the logic so that we
        always blow away the old shadow tree. Moved the comment about rebuilding things
        every time here. Updated the code to use the findTarget and cloneTarget functions,
        eliminating the buildShadowTree function entirely. Moved the call to
        transferSizeAttributesToShadowTreeTargetClone inside cloneTarget. Also updated
        for the name change for m_shouldRebuildShadowTree.
        (WebCore::SVGUseElement::targetClone): Renamed from shadowTreeTargetClone.
        No need to emphasize "shadow tree" since that's where all clones are.
        (WebCore::isDirectReference): Streamlined a bit using "using namespace".
        (WebCore::SVGUseElement::toClipPath): Rewrote to use early return and updated
        for name changes. Also used ASCIILiteral.
        (WebCore::SVGUseElement::rendererClipChild): Changed local variable names.
        (WebCore::removeDisallowedElementsFromSubtree): Wrote the iteration in a
        slightly more idiomatic style.
        (WebCore::SVGUseElement::findTarget): Added. This new function implements
        the rule for finding a valid target for a use element. This replaces logic
        that was duplicated in two different places and it also includes all the
        rules that were formerly in the isValidTarget function. Also, this implements
        a correct check for a cycle that handles cases the code in isValidTarget did not.
        (WebCore::SVGUseElement::isValidTarget): Deleted.
        (WebCore::SVGUseElement::cloneTarget): Added. Helper function used both when
        cloning the target of the top level <use> elements and for other <use> elements
        inside the shadow tree.
        (WebCore::cloneDataAndChildren): Added. Helper function that allows both the
        <use> and <symbol> element expanding functions to be shorter and share more code.
        (WebCore::SVGUseElement::expandUseElementsInShadowTree): Removed unneeded checks
        of cachedDocumentIsStillLoading. Used the new findTarget function, which handles
        finding the target cross-document correctly. Removed the incorrect use of
        referencedDocument when creating new elements and finding targets. Refactored
        to use the new cloneDataAndChildren function and also moved the code that removes
        the special attributes here, replacing the transferAttributesToShadowTreeReplacement
        function. Made a few other simplifications.
        (WebCore::SVGUseElement::expandSymbolElementsInShadowTree): Ditto, just like the
        <use> changes only simpler.
        (WebCore::SVGUseElement::transferEventListenersToShadowTree): Made this const.
        Removed unneeded assertions.
        (WebCore::SVGUseElement::invalidateShadowTree): Updated for name change.
        (WebCore::SVGUseElement::invalidateDependentShadowTrees): Removed assertion.
        (WebCore::SVGUseElement::transferAttributesToShadowTreeReplacement): Deleted.
        (WebCore::SVGUseElement::selfHasRelativeLengths): Tweaked names.
        (WebCore::SVGUseElement::notifyFinished): Removed the inDocument check, since
        this function will only be called for elements that are in a document.
        (WebCore::SVGUseElement::cachedDocumentIsStillLoading): Deleted.
        (WebCore::SVGUseElement::finishParsingChildren): Removed the code that calls
        buildPendingResource here. Shadow tree updating is driven solely by renderer
        generation now.
        (WebCore::SVGUseElement::updateExternalDocument): Replaced setCachedDocument
        with this. This function knows how to load a different document if the URL
        has changed, or leave it alone if not, and also stop the load if it should.
        (WebCore::SVGUseElement::isValid): Moved this here from the header, since it's
        always being called virtually.
        (WebCore::SVGUseElement::haveLoadedRequiredResources): Ditto.
        (WebCore::SVGUseElement::setHaveFiredLoadEvent): Ditto.
        (WebCore::SVGUseElement::haveFiredLoadEvent): Ditto.
        (WebCore::SVGUseElement::svgLoadEventTimer): Ditto.

        * svg/SVGUseElement.h: Removed unneeded include. Moved the animated properties
        to the top of the class because they are public DOM API and so are logical to
        list first. I'd like to do that for other classes too over time. Changed to
        derive privately from CachedSVGDocumentClient. Made the function
        invalidateDependentShadowTrees private. Removed didNotifySubtreeInsertions,
        isSupportedAttribute, clearResourceReferences, buildShadowTree,
        transferAttributesToShadowTreeReplacement, isParserInserted, and
        m_wasInsertedByParser. Added updateExternalDocument, cloneTarget, targetClone,
        updateShadowTree, and clearShadowTree. Also did a couple other renames,
        including renaming m_cachedDocument to m_externalDocument.

        * svg/svgtags.in: Removed constructorNeedsCreatedByParser from the <use>
        element since we don't have to handle constructing by the parser specially.

        the flowthread containing block and we end up with dangling pointers in this map.

        Reviewed by Eric Carlson.

        Apparenty -[AVPlayer rate] means different things for HLS and progressive content; for progressive,
        the -rate is the actual rate of playback. For HLS, the -rate is the requested rate, and will return
        the requested value even if time is not progressing.

        We added the currentTime estimation engine because asking AVFoundation for its -currentTime used to
        be expensive, but we've been assured that in recent iOS and OS X releases, -currentTime should be
        very fast. That, in combination with the HLS behavior of -rate and how it breaks the currentTime
        estimation, means we should probably turn it off for iOS and Yosemite.

        ASSERTION FAILED: resolvedInitialPosition <= resolvedFinalPosition in WebCore::GridSpan::GridSpan
        https://bugs.webkit.org/show_bug.cgi?id=141328

        Reviewed by Darin Adler.

        Whenever
        GridResolvedPosition::resolveGridPositionsFromAutoPlacementPosition()
        was trying to place an item with span, it was completely ignoring
        the resolvedInitialPosition returned by
        GridResolvedPosition::resolveGridPositionAgainstOppositePosition()
        and only using the finalResolvedPosition. This works with an
        unlimited grid which can indefinitely grow. But if the item spans
        over the grid track limits, then it might happen that the final
        resolved position is placed before the initial resolved position,
        something that is forbidden.

        The solution is to directly use the GridSpan returned by
        GridResolvedPosition::resolveGridPositionAgainstOppositePosition(), if the item
        does not surpass the track limits then the returned initialResolvedPosition
        is identical to the provided one, otherwise it's properly corrected to respect
        track boundaries.

        [CSS Grid Layout] Tracks' growth limits must be >= base sizes
        https://bugs.webkit.org/show_bug.cgi?id=140540

        Reviewed by Antti Koivisto.

        The track sizing algorithm is supposed to avoid those situations
        but they easily (specially when we mix absolute lengths and
        intrinsic lengths in min and max track sizing functions) and
        frequently appear. In those cases the outcome from the algorithm
        is wrong, tracks are not correctly sized.

        In order to fulfill the restriction, m_usedBreadth and
        m_maxBreadth are now private members of GridTrack and the class
        now provides a couple of methods to modify them respecting the
        growthLimit >= baseSize precondition.

        Apart from that, the members and methods of GridTrack were also
        renamed to match the ones used in the recent algorithm rewrite:
        usedBreadth became baseSize and maxBreadth is now growthLimit.

        Although the algorithm was not modified at all, this change
        detected and fixed several invalid results (tracks and/or grids
        bigger than expected).

        Excuse of a grammar: http://dev.w3.org/csswg/selectors-4/#grammar

        This patch also covers serialization for CSSOM. The serialization
        is defined here: http://dev.w3.org/csswg/cssom/#serializing-selectors

        Matching is completely ignored in this patch. All the simple selectors
        are treated as regular attribute selectors.

        Tweak inline playback controls to match system spec

        Reviewed by Sam Weinig.

        Rework the UI of the inline media controls on iOS, to
        better match the system specification. I've batched a
        few changes into one patch because many of them are
        inter-dependent, and not very aggressive. Changes are:

        - updated artwork for the buttons.
        - separate artwork for normal and active states.
        - background images are now explicitly sized and positioned
          in the middle of the element, allowing audio and video
          to use the same glyphs even though the elements are
          different sizes.
        - use plus-darker blend mode on the button glyphs.
        - rearranged some of the rules to group things in a
          logical order.
        - time should front-pad a "0" character, if less than 10.
        - no need for an "active" class on the Airplay button (although
          I won't be surprised if this changes back).

        * dom/ElementIterator.h: Changed the * and -> operators to be const.
        There is no need for the iterator itself to be modified just to dereference it.

        * dom/TypedElementDescendantIterator.h: Added DoubleTypedElementDescendantIterator.
        This allows callers to call descendantsOfType on two elements, as long as the caller
        can guarantee that both have the same number of descendants of that type. It's handy
        for walking a tree of cloned elements to set up something between each original and
        its clone. In the future we might instead change the cloning machinery so it can do
        this work as we clone, and if so, we could consider deleting this.

        * svg/SVGElement.cpp:
        (WebCore::SVGElement::correspondingElement): Made this const.
        (WebCore::SVGElement::invalidateInstances): Got rid of the rule that said "this can
        only be done for an element in a document", since it's useful to do this on an element
        that has just been removed from a document. Removed the "updateStyleIfNeeded" call
        here now that the other changes make it no longer needed. Removed an unimportant
        assertion that we only invalidate use elements that are in a document; that's not
        a necessary restriction. Streamlined the logic a bit.

        (WebCore::SVGUseElement::svgAttributeChanged): Changed code that transfers
        size attributes to the shadow tree to use shadowTreeTargetClone instead of
        m_targetElementInstance.
        (WebCore::SVGUseElement::clearResourceReferences): Removed code to detach
        m_targetElementInstance, and also the call to removeAllTargetReferencesForElement,
        because we no longer use those.
        (WebCore::SVGUseElement::buildPendingResource): Moved the code to build the
        shadow tree in here and deleted the buildShadowAndInstanceTree function.
        Also changed logic so that we use a pending resource any time the target is not
        a valid one. That helps us correctly handle cases where we initially have an
        invalid target, but later get a value one
        (WebCore::SVGUseElement::buildShadowAndInstanceTree): Deleted. The code here
        was greatly simplified and moved into buildPendingResource.
        (WebCore::SVGUseElement::buildInstanceTree): Deleted.
        (WebCore::SVGUseElement::hasCycleUseReferencing): Deleted. Cycles are now

        (WebCore::associateClonesWithOriginals): Added. Helper that makes
        functions that build the shadow tree simpler and easier to read.

        (WebCore::SVGUseElement::buildShadowTree): Call associateClonesWithOriginals
        since associateInstancesWithShadowTreeElements no longer does this.
        (WebCore::SVGUseElement::isValidTarget): Added. Covers all the different
        reasons a target might not be valid: type of element, reference cycles, and
        also "not in document" (refactored in here; not sure when that can happen
        in practice, might be possible to remove it later).
        (WebCore::SVGUseElement::expandUseElementsInShadowTree): Add checks for
        documents that are still loading; this used to be checked when building the
        instance tree. Added calls to associateReplacementClonesWithOriginals and
        associateClonesWithOriginals; that used to be done by later in the
        associateInstancesWithShadowTreeElements function. Use isValidTarget so
        we handle cycles as well as invalid target types.
        (WebCore::SVGUseElement::expandSymbolElementsInShadowTree): Added a call to
        associateReplacementClonesWithOriginals, since we can no longer do that in
        associateInstancesWithShadowTreeElements.
        (WebCore::SVGUseElement::associateInstancesWithShadowTreeElements): Deleted.
        (WebCore::SVGUseElement::instanceForShadowTreeElement): Deleted.

        that simply restated the name of the function.

        buildShadowAndInstanceTree, detachInstance, buildInstanceTree,

        When not in a layer tree, AVFoundation is not able to determine the correct mapping from logical

        both the current device scale and the current page scale.

        Since this needs to be set at initialization time, before the AVPlayer is has any AVPlayerItems,

        Invalid cast in WebCore::SVGAnimateElement::calculateAnimatedValue.
        https://bugs.webkit.org/show_bug.cgi?id=135171.

        Reviewed by Dean Jackson.

        The bug happens when an SVG element is animated by <animateMotion> followed by an
        <animateColor> or an <animate> and the values of the "attributeName" in both elements
        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.

        If two compositing layers were adjoining but not overlapping, but happened to
        have non-integral offsets, then using enclosing IntRects in the overlap map
        would cause us to think they are overlapping, and create unnecessary backing store.
        
        Fix by converting the overlap map to use LayoutRects.

        Reviewed by Antti Koivisto.

        In MemoryCache::pruneLiveResourcesToSize(), we were iterating over the
        m_liveDecodedResources ListHashSet and possibly calling
        CachedResource::destroyDecodedData() on the current value. Doing so
        would cause a call to ListHashSet::remove() to remove the value pointed
        by the current iterator, thus invalidating our iterator.

        In this patch, we increment the ListHashSet iterator *before* calling
        CachedResource::destroyDecodedData(), while the current iterator is
        still valid. Note that this is safe because unlike iteration of most
        WTF Hash data structures, iteration is guaranteed safe against mutation
        of the ListHashSet, except for removal of the item currently pointed to
        by a given iterator.

        Do not destroy RenderQuote's text fragment child when quotation mark string is changing.
        https://bugs.webkit.org/show_bug.cgi?id=141271
        rdar://problem/18169375

        Reviewed by Antti Koivisto.

        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.

        When using SVG as an image, we should load datauri images when these images are not in the image cache.

        Data URI sub-resources are not loaded because the networking context of FrameLoader
        attached to the SubResourceLoader is set to null. This is done intentionally to
        disallow any resource from loading external sub-resources. For example if an <img>
        tag has its 'src' attribute points to an svg file, this svg is not allowed to load
        an external image through the 'xlink' attribute of an <image> element. This restriction
        is not valid if the value of the 'xlink' attribute is a data URI. In this case the image 
        should be loaded into memory since there is no network traffic involved. All we need
        to do is to decode the data part of the URI.
        
        The fix is to pass the root FrameLoader, which has a valid NetworkingContext, through
        the FrameLoaderClient, to the ResourceHandle::create() which uses the NetworkingContext
        to decode the data and fire the load events of the data URI resources.

        It's possible to submit a RemoteLayerTree transaction that contains data
        about a created layer, but doesn't have any properties for that layer. This
        happens when the newly created layer isn't reached during the traversal that
        gathers layer properties (i.e. it's not rooted). However, whether we create
        a scrolling layer or not requires having properties; they are missing, so we
        create a normal layer, but then the scrolling tree commit asserts that we
        should have a scrolling layer.
        
        Fix by making scrolling layers have a corresponding layer type, which is
        stored in layer creation properties. This required exposing layer types
        up through GraphicsLayer, but that allows for some nice cleanup:
        
        1. No need to have the hokey shouldUseTiledBacking() GraphicsLayerClient hack
           for creating the page tiled layer.
        2. The notion of "custom behaviors" can be removed from GraphicsLayer entirely.

        Not testable because it requires tab switching.

        Smart quoting could move the caret backwards in some configurations
        https://bugs.webkit.org/show_bug.cgi?id=141203
        <rdar://problem/17452543>

        Reviewed by Enrica Casucci.

        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.

        This patch adds the code generator for :nth-last-child(), skipping
        any :nth-last-child(An+B of selector list).

        The code generator is boring here, nothing fancy.
        There is no optimization opportunity here so it is basically the same
        speed as the code generated by Clang when the simple selector is alone.

        The only reason to JIT compile this is to avoid going to slow-path

        Clean up attribute handling: part 2 - attributeNode
        https://bugs.webkit.org/show_bug.cgi?id=141109

        Reviewed by Andreas Kling.

        Our implementation was covering some old legacy behaviors of Firefox,
        even copying bugs in some cases.

        The spec (https://dom.spec.whatwg.org) now defines the behavior precisely,
        let's move a bit closer to that.

        * dom/Element.cpp:
        (WebCore::findAttrNodeInList):
        New getter for the name-without-namespace case.

        (WebCore::Element::setAttributeNode):
        This one is the tricky one: https://dom.spec.whatwg.org/#dom-element-setattributenode

        When setAttributeNode() is used with an AttributeNode without namespace,
        getting the old value behaves like getAttribute(), with ASCII lowercase name matching.
        When used with a namespace, getting the old value behaves like getAttributeNS().

        Setting the value is a whole different story, the name used always keeps
        the original case.

        Now that's a bit tricky for us because AttributeNodes are just legacy stuff we don't
        used internally.

        We have 4 cases to handle:
        1) The name being set is lowercase, there was no conflicting name on the element.
           That's easy, we just override any node that would exist, set the name otherwise.
        2) The name is lowercase but there was an existing attribute for it.
           -We create a new AttributeNode for the name to represent the old name.
           -We check the names are the same with attribute.name().matches(attrNode->qualifiedName())
            and override the value.
        3) The name has uppercase characters, there is no conflicting name.
           We would not find an element to remove, we just use setAttributeInternal() as usual
           to add the attribute;
        4) The name has uppercase characters, there is a lowercase conflicing name.
           This is the weird behavior: we need to nuke the old attribute, then add the new attribute
           with a different case.

           First we remove the attribute with a lowercase name with removeAttributeInternal().
           That becomes the old node.

           There might still be an element of the same name as what we are trying to add. We don't want
           to add another version of the same attribute. We need to use findAttributeIndexByName() again
           to find if there is a conflicting attribute. Then we call setAttributeInternal() which handle
           the both the cases where there was an element or not.

        (WebCore::Element::setAttributeNodeNS):
        This should work like any "NS" method.

        Reviewed by Antti Koivisto.

        Re-landing this patch since it turned out to not be the cause of
        the memory regression we saw around that revision.

        Mark decoded images as "transient" which makes CoreGraphics mark
        the backing stores as purgeable shortly after they're used.

        The decoded representation will remain in CoreGraphics's caches
        indefinitely unless the kernel gets starved and needs the pages.

        Most resources will now reach a state where the encoded data is
        mmap'ed from disk cache (once the entire resource is downloaded)
        and the decoded data is purgeable.

        This also has the side effect of making the MemoryCache more
        palatial since the decoded data cost can be deducted for images,
        allowing us to cache more resources.

        Note that the worst case for this new behavior would be something
        like hovering below 100% memory utilization and constantly having
        to drop and re-decode images. While churny, it still beats
        crashing the process, plus there's tiling to remove many of the
        reasons we'd need the decoded data.

        Instead of reducing a null selector, we can use a real parsing error
        to get out of invalid selector endings.

        When that happens, Bison will pop the stack until it can reduce any
        valid error recovery rules.

        The problem is to make sure there is no floating values because
        none of the reduce block between the error and the recovery would
        be executed.

        In this case, "nth_selector_ending" is a non-recursive production of
        the NTHCHILDFUNCTIONS. In turn, NTHCHILDFUNCTIONS are productions
        of the non-recursive "pseudo". "pseudo" is only used as a trivial
        production of "specifier". "specifier" is only used by "specifier_list".

        "specifier_list" has error recovery code -> no production could have
        generated a floating values between "specifier_list" and "nth_selector_ending".

        REGRESSION (r170576): Storage leaks in parsing of CSS image sizes
        https://bugs.webkit.org/show_bug.cgi?id=141026

        Reviewed by Anders Carlsson.

        * css/CSSGrammar.y.in: Fixed all the shift/reduce conflicts caused
        by the ENABLE_PICTURE_SIZES code by removing all the redundant
        maybe_space which caused them. Rearranged the productions for
        ENABLE_PICTURE_SIZES to tighten up the code quite a bit. Changed
        the code to build up the source size vector as a Vector instead of
        a special class, and use the SourceSize struct from inside the
        CSSParser class.'

        * css/CSSParser.cpp:
        (WebCore::CSSParser::setupParser): Changed this to take a StringView.
        In the future we can change all the parsing functions to take StringView,
        since they don't work with the String in place.
        (WebCore::CSSParser::parseSizesAttribute): Changed to return a vector
        of SourceSize instead of a SourceSizeList. This is better because it's
        a real CSS data structure that does not contain a CSSParserValue.
        (WebCore::CSSParser::sourceSize): Added. Helper that creates a
        SourceSize, mapping parser data structures into real CSS ones.

        * css/CSSParser.h: Updated for changes above.

        * css/MediaQuery.cpp:
        (WebCore::MediaQuery::MediaQuery): Use std::make_unique and the copy
        constructor directly instead of using a MediaQuery::copy function.

        * css/MediaQueryExp.cpp: Streamlined the class a little bit.
        * css/MediaQueryExp.h: Removed unneeded includes. Moved functions out
        of the class body so the class is easier to read. Removed the unneeded
        copy function.

        * css/SourceSizeList.cpp:
        (WebCore::SourceSize::match): Changed to use WTF::move instead
        of releasing and then re-creating the unique_ptr.
        (WebCore::computeLength): Added a comment to explain this function
        is using an incorrect strategy. Also added some type checking code
        to handle cases where a null or non-primitive CSS value might be
        returned. Probably dead code, but we don't want to risk a bad cast.
        Worthe cleaning up when we fix the strategy.
        (WebCore::SourceSizeList::getEffectiveSize): Updated since the
        vector now contains actual SourceSize objects rather than pointers
        to SourceSize objects on the heap.

        * css/SourceSizeList.h: Changed the CSSParserValue argument to be
        an rvalue reference to make it clearer that we take ownership of it
        when it's moved in. Added a move constructor and a destructor. Added
        comments explaining that it's not correct design to use a
        CSSParserValue here, outside the parser. Changed SourceSizeList's
        append function to move a SourceSize in rather than a unique_ptr.
        Made getEffectiveSize private. Moved the various inline functions to
        the bottom of the file to make the class definitions easier to read.


        * css/SourceSizeList.cpp: Made almost everything about this private
        to this source file instead of public in the header.
        (WebCore::match): Made this a free function instead of a member function
        and made it take the media query expression as an argument.
        (WebCore::computeLength): Changed the argument type to CSSValue*,
        rather than using CSSParserValue here outside the parser.
        (WebCore::parseSizesAttribute): Streamlined and simplified this.
        Now that the parser builds the list in the correct order, there was
        no need to iterate backwards any more so we could use a modern for
        loop.

        * css/SourceSizeList.h: Removed almost everything in this header.

        * html/HTMLImageElement.cpp:
        (WebCore::HTMLImageElement::parseAttribute): Call the
        parseSizesAttribute function as free function since it's no longer
        a member of a SourceSizeList class.

        Use simpler CachedResourceMap structure in MemoryCache with CACHE_PARTITIONING enabled
        https://bugs.webkit.org/show_bug.cgi?id=141110

        Reviewed by Antti Koivisto.

        Use simpler CachedResourceMap structure in MemoryCache with CACHE_PARTITIONING
        enabled. Previously, we would be using a HashMap of HashMap to store
        CachedResources. The outer HashMap would use the URL as key and the inner
        HashMap would use the partition name as key. This would make traversing the
        structure overly complicated, especially considering that the code needs to
        traverse a simple HashMap if CACHE_PARTITIONING is disabled.

        This patch updates the CachedResourceMap structure to be a simple HashMap,
        whose key is an std::pair<URL, String /* partitionName */>. Having a flat
        structure simplifies the traversal code a lot and enables more code sharing
        between CACHE_PARTITIONING and !CACHE_PARTITIONING. This shouldn't regress
        performance because we always have both a URL and a partition name when we
        need to look up a resource. We never need to retrieve all resources with
        a particular URL.

        This patch also switches to using a URL as key instead of a String as we
        always have a URL has input.

                Since this is not used anywhere, I dropped this ability.
            - iOS took additional inputs of initial bidi status and run length (and returned the

                Since this was also unused, I dropped it.
            - iOS used the fact that font.drawText() returns the length that was drawn, to avoid
              measuring the text twice.

        RenderBlock also had a cache of its line-height, but it doesn't appear

        When a breakable text fragment does not fit the current line, we split it.
        The first part stays on the current line, while the second part gets pushed to the next line.
        In certain cases, the first part could end up being empty.

        Reviewed by Antti Koivisto.

        Store MemoryCache's live decoded resources in a ListHashSet instead of
        a linked list. The frequent operations are:
        1. Add items to one end
        2. Remove items from the other end or anywhere in the container by value

        Using a ListHashSet instead of a manual linked list results in *much*
        simpler / shorter code and is fast for all operations (faster than
        linked list even for removing an given element from the container given
        its value). The previous implementation required us to keep a lot of
        pointers up-to-date, which was error prone.

        This is a first step towards simplifying the MemoryCache implementation.

        Border-radius clipping on a stacking context causes descendants to not render

        Reviewed by Zalan Bujtas.
        
        Fix one of the issues introduced in r178029. The changes in GraphicsLayerCA
        failed to adhere to the "set a bit and flush later" pattern that this class uses,
        instead poking the platform layers directly. This caused an issue where the bounds
        of the clipping layer would later be set to 0x0, causing content to disappear.
        
        Fix by changing the "applyClippingBorder" function to "setMasksToBoundsRect"
        and have it update via a new MasksToBoundsRectChanged dirty bit.

        In order to avoid clobbering the mask layer used to clip contents, we need another
        shape mask layer, so rename m_shapeMaskLayer to m_contentsShapeMaskLayer, then
        introduce a new m_shapeMaskLayer which is used for masks-to-bounds clipping. Update
        the reflection cloning code to correctly clone this layer.

        This patch has to add support for following line breaking rules at both
        sides of a Ruby boundary. For breaking before a Ruby, unfortunately we
        just hard-code the rules (and apply this hard-coding only to Ruby and not
        to other inline replaced elements).

        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.

        When constructing a JS wrapper object, there is always going to be a
        corresponding DOM object.

        Tweak the JavaScript DOM bindings generator to spit out constructors
        that take the DOM object by Ref&& rather than PassRefPtr.

        This avoids generating unnecessary null checks around every instance

        Reviewed by Darin Adler.

        Clean up / modernize PageCache class:
        - Use more references instead of pointers
        - Use a ListHashSet<Ref<HistoryItem>> internally instead of a linked
          list of HistoryItem*. This avoids having the ref/unref HistoryItems
          manually and maintaining the list size separately. It also simplifies
          the code dealing with the container and makes looking up HistoryItems
          faster as a bonus. Similarly to the previous implementation, we are
          adding elements to one end and removing from the opposite end when
          pruning to drop old history items first. Note that even though the
          previous implementation was called LRUList, it did not move items to
          the front when accessed. The new implementation doesn't either.
         - Rename "capacity" to "maxSize" to avoid confusing with containers'
           capacity (which doesn't limit the size of the container).
         - Use unsigned instead of int for all values that are supposed to be
           positive.
         - Do not explicitely define the default constructor and let the
           compiler generate it for us (and use in-class initialization for
           members)

        CachedImage: ensure clients overrides imageChanged instead of notifyFinished
        https://bugs.webkit.org/show_bug.cgi?id=140722

        Reviewed by Tim Horton.

        imageChanged is called whenever a frame of an image changes
        because we got more data from the network.

        notifyFinished was called when the image was entirely loaded.

        The problem was that some clients were implementing only
        imageChanged (ex: RenderBox), some only notifyFinished and
        some both (ex: RenderImage) which made the situation difficult
        to understand and to maintain.

        For example when the image finished loading, both imageChanged
        and notifyFinished were called with the difference that for the
        first one isLoaded() returned false.
        It could result in functions being called twice in a row,
        ex: contentChanged(ImageChanged).

        So this patch tries to simplify the situation by marking
        CachedImageClient::notifyFinished final in order to prevent
        clients from implementing it.
        Indeed this patch ensure that CachedImage clients implement
        and only implement imageChanged function.

        Also Clients can now differentiate intermediate and end
        calls by checking isLoaded() in imageChanged.

        Use an enum class for createFontFamilyValue()'s fromSystemFontID argument
        instead of a simple enum, as suggested by Sam. This is a bit nicer.

        Also, use a boolean type for CSSFontFamily.fromSystemFontID instead of
        the enum type to facilitate handling. Using a enum (class) for
        CSSFontFamily's fromSystemFontID member is not useful as it is always
        accessed by name.

        Refactoring of code that is pretty well covered by existing tests, so
        not adding new tests.

        Inspired by work Rob Buis did in Blink:

        This behavior doesn't seem to be needed to pass any existing tests, and Rob
        removed it from Blink, so I'll take it out and we can bring if back, based
        on the original element rather than on the SVGElementInstance, if we find we

        this element from the instances set of the corresponding element.

        an out argument. Also had to change some since the vectors are in the hash table
        now rather than allocated on the heap.
        (WebCore::SVGAttributeToPropertyMap::types): Renamed from
        animatedPropertyTypeForAttribute and made changes just like the ones above.
        (WebCore::SVGAttributeToPropertyMap::synchronizeProperties): Use modern for
        loops, take a reference rather than a pointer, and use the function pointer
        directly instead of calling through a helper with various assertions.
        (WebCore::SVGAttributeToPropertyMap::synchronizeProperty): Ditto.

        * svg/properties/SVGAttributeToPropertyMap.h: Updated to match the changes
        above. Also changed the map to contain vectors instead of pointers to vectors.

        HTMLElement.dir should only return known values according to the HTML

        Chrome and Firefox 28 match the specification. IE11's behavior is
        slightly different:
        - When setting an unknown 'dir' value, an exception will be thrown.
        - Setting a known 'dir' value in a non-canonical case (e.g. "RTL"),
          the value will be directly converted to its canonical form (e.g.
          "rtl") before updating the DOM tree. (close to the spec but changing

        This patch does not change behavior, it merely ports calls sites that

        https://bugs.webkit.org/show_bug.cgi?id=140902

        Reviewed by Andreas Kling.

        Rename Document::body() to Document::bodyOrFrameset() for clarity. This
        method does not necessarily return an HTMLBodyElement, it can also
        return a frameset as per the specification:
        http://www.w3.org/TR/html5/dom.html#dom-tree-accessors

        This method is often misused internally (the caller is only interested
        in the <body> element). I will fix these instances in a follow-up patch,
        this patch is only renaming mechanically.

        Simplify RenderElement's shouldRepaintForImageAnimation()
        https://bugs.webkit.org/show_bug.cgi?id=140890

        Reviewed by Darin Adler.

        Simplify RenderElement's shouldRepaintForImageAnimation() by
        not calling rendererForRootBackground(). The previous code was
        doing a null-check on Document::documentElement() but failing
        to do a null-check on the renderer just after, which lead me
        to refactor this code.

        Instead of calling document().documentElement.renderer(), we
        now call renderer.parent(). This is equivalent because we already
        know that renderer.isBody() returns true. The parent of the <body>
        has to be the <html> element, which has to be the documentElement.
        There is also no need to do a null-check on renderer.parent(). We
        already know that the <body> has a renderer (because |renderer| is
        its renderer), thus its parent <html> element has to have a renderer
        as well.

        Finally, simply call !rootElement.hasBackground() instead of
        rootElement.rendererForRootBackground() == &bodyRenderer to determine
        if the background painted by the root. This is equivalent but more
        efficient because:
        - We already know that the root renderer's is an <html> element. We
          can thus avoid the check in rendererForRootBackground().
        - We already have the <body>'s renderer so we don't need to do the
          DOM tree traversal in rendererForRootBackground() to get it.

        Fix CSS Selector's tag name matching when mixing HTML and XML
        https://bugs.webkit.org/show_bug.cgi?id=140878

        Reviewed by Darin Adler.

        Previsouly, WebKit was unable to match any XML element that had
        any uppercase character if the stylesheet was in a HTML document.
        This problem was most often reported due to the inability to style
        SVG-in-HTML.

        The reason was that the tag local name was incorrectly transformed
        to lowercase at parsing time. Instead, we are supposed to only
        do case-insensitive match for HTML elements in a HTML document.

        This fix is very similar with how we handle attributes:
        -Keep both the original and the lowercase versions of the name.
        -When matching, chose which version to use depending on the element being matched.

        There is one major difference in the way the names are stored.
        Unlike attribute selectors, tag name selectors are common, and the uppercase
        version is not that uncommon. I wanted to preserve the dense representation
        so I specialized CSSSelector specifically for tag names.

        To store the data, if the name is already lowercase, just use the m_data pointer
        as usual.
        If the name is not lowercase, allocate a new small structure in the union to store
        both names.

        To make it work, all names are now converted to lowercase.
        That implies that we can filter less on XML and we may have to pay for
        converting the tag name to lowercase.

        I expect the performance hit to be small because:
        -Having two XML elements with the same name but different case is uncommon.
        -Most elements use lowercase names.

        Still sad...that's the price to pay for correctness.

        Reviewed by Anders Carlsson.

        Refactoring of code that is pretty well covered by existing tests, so
        not adding new tests.

        Inspired by work Rob Buis did in Blink:

            http://src.chromium.org/viewvc/blink?view=revision&revision=173273

        Althgouh that is less than half of what ended up in this patch.

        * dom/ContainerNode.h: Fixed NoEventDispatchAssertion so it can be
        copied without causing an underflow of NoEventDispatchAssertion::s_count.
        Made the copy constructor call the default constructor. Also changed it
        to be based on ASSERT_DISABLED rather than NDEBUG and tweaked it a bit.

        * dom/ElementIteratorAssertions.h: Removed an unnecessary include and
        an unnecessary default constructor. Changed to use WTF::Optional instead
        of WTF::OwnPtr to handle NoEventDispatchAssertion, which makes this class
        copyable and assignable, which in turn makes the iterators based on this
        copyable and assignable, which is what I needed in SVGUseElement code.
        Also simplified code in a couple places.

        * dom/TypedElementDescendantIterator.h:
        (WebCore::TypedElementDescendantIteratorAdapter<ElementType>::from):
        Fixed an error where the arguments to Traversal::next were passed backwards.
        This led to incomplete iteration in SVGUseElement code, and an immediate
        assertion failure. Probably could use some unit test coverage, too.
        (WebCore::TypedElementDescendantConstIteratorAdapter<ElementType>::from):
        Ditto.

        * svg/SVGUseElement.cpp:
        (WebCore::SVGUseElement::animatedInstanceRoot): Deleted.
        (WebCore::SVGUseElement::transferSizeAttributesToShadowTreeTargetClone):
        Removed the originalElement argument, since we can use the correspondingElement
        to get back to it. Removed the useElement argument and changed this into a
        member function.
        (WebCore::SVGUseElement::svgAttributeChanged): Updated for above changes.
        (WebCore::subtreeContainsDisallowedElement): Deleted this function, because
        it was only used to optimize by not calling removeDisallowedElementsFromSubtree,
        but that function is already similarly efficient when called to do nothing, so
        the preflight was not useful.
        (WebCore::SVGUseElement::clearResourceReferences): Call userAgentShadowRoot
        instead of shadowRoot for clarity.
        (WebCore::SVGUseElement::buildPendingResource): Pass a reference instead of
        a pointer to buildShadowAndInstanceTree, since it's guaranteed to not be null.
        (WebCore::SVGUseElement::shadowTreeTargetClone): Added. Returns the SVG element
        inside the shadow tree that corresponds to the use element's target.
        (WebCore::SVGUseElement::buildShadowAndInstanceTree): Changed argument type
        to a reference instead of a pointer. Removed comments explaining why we have
        an instance tree, since soon we will not have one. Removed many comments that
        simply state the names of the functions they are commenting on and perhaps a tiny
        bit more. Changed to not use m_targetElementInstance as much, dealing with the
        shadow tree directly instead of through the instance tree.
        (WebCore::SVGUseElement::toClipPath): Use shadowTreeTargetClone instead of
        getting at the element through m_targetElementInstance.
        (WebCore::SVGUseElement::rendererClipChild): Ditto.
        (WebCore::removeDisallowedElementsFromSubtree): Removed the inline keyword,
        since there's no good reason to inline thif function's body. Improved local
        variable names and used a modern for loop. Also moved the comment about why
        this function is used here inside the function instead of repeating it at
        each call site.
        (WebCore::SVGUseElement::buildShadowTree): Changed to take a reference
        instead of a pointer. Moved the check to see if the target is disallowed
        out of this function and into buildShadowAndInstanceTree, which needs to
        handle that failure explicitly. Tightened up the code a bit, using Ref instead
        of RefPtr, putting the comment about removeDisallowedElementsFromSubtree into
        that function itself, and removing the unneeded subtreeContainsDisallowedElement
        check entirely.
        (WebCore::SVGUseElement::expandUseElementsInShadowTree): Removed the argument,
        getting the shadow tree from the shadowTree function instead. Walk the tree
        iteratively instead of recursively, using the descendantsOfType function.
        Rearranged and streamlined the logic.
        (WebCore::SVGUseElement::expandSymbolElementsInShadowTree): Ditto.
        (WebCore::SVGUseElement::transferEventListenersToShadowTree): Ditto.
        (WebCore::SVGUseElement::transferAttributesToShadowTreeReplacement): Renamed
        this to avoid the term "replaced element", which is not a reasonable way to
        refer to the <g> element in the shadow tree that replaces the <use> element.
        Changed the argument type to SVGGElement to make it harder to misuse this
        function by accident, and made the use element be "this" instead of passing
        it as an argument.
        (WebCore::SVGUseElement::selfHasRelativeLengths): Call hasRelativeLengths
        on the target inside the shadow tree rather than the original target, which
        makes more sense anyway, and is straightforward now that we have the
        shadowTreeTargetClone function. Removes use of m_targetElementInstance here.

        * svg/SVGUseElement.h: Updated for above changes.

        * svg/SVGUseElement.idl: Removed animatedInstanceRoot and tweaked formatting.

        Remove 'font' shorthand property special casing
        https://bugs.webkit.org/show_bug.cgi?id=140577

        Reviewed by Darin Adler.

        Expand system font values during 'font' property parsing. The 'font'
        CSS property was the only shorthand that wasn't always expanded in
        the CSS parser, so it needed a lot of special handling that we can
        now get rid of.

        This patch is inspired from the following Blink revision:
        https://src.chromium.org/viewvc/blink?view=rev&revision=184449

        Tests:
        - fast/css/css2-system-fonts.html (existing)
        - fast/css/CSSPrimitiveValue-font-family-primitiveType.html (new)
        - fast/css/font-systemFontID-parsing.html (new)
        - fast/css/font-shorthand-line-height.html (rebased)

        * WebCore.xcodeproj/project.pbxproj:
        * css/CSSCalculationValue.cpp:
        (WebCore::hasDoubleValue):
        Handle CSS_FONT_FAMILY similarly to CSS_STRING in the switch.

        * css/CSSFontFamily.h: Added.
        Introduce new CSSFontFamily class to store font families inside
        CSSPrimitive, instead of using a simple String as previously. We need
        an additional 'fromSystemFontID' flag in addition to the font family
        name now that system font ID are expanded during parsing. This
        information is needed later on by the StyleBuilder (see comment below).

        * css/CSSFontSelector.cpp:
        (WebCore::CSSFontSelector::addFontFaceRule):
        Update code dealing with font family CSSPrimitiveValues now that they
        hold a CSSFontFamily internally instead of a String.

        * css/CSSParser.cpp:
        (WebCore::CSSParser::parseValue):
        (WebCore::CSSParser::parseSystemFont):
        Expand system font values for the 'font' property by asking the
        RenderTheme for the system font and using it to set the 'font'
        longhand properties.

        * css/CSSParserValues.cpp:
        (WebCore::CSSParserValue::createCSSValue):
        Handle CSS_FONT_FAMILY value in the switch.

        * css/CSSPrimitiveValue.cpp:
        (WebCore::CSSPrimitiveValue::primitiveType):
        Make sure we still expose font family CSSPrimitiveValues to the Web as
        CSS_STRING, even though we are using a slightly different representation
        internally. This is so that we don't change web-exposed behavior and I
        added a new layout test to cover this.

        (WebCore::CSSPrimitiveValue::cloneForCSSOM):
        (WebCore::CSSPrimitiveValue::equals):
        Handle CSS_FONT_FAMILY type in switches.

        * css/CSSPrimitiveValue.h:
        (WebCore::CSSPrimitiveValue::isFontFamily):
        Add method to test if a CSSPrimitiveValue holds a CSSFontFamily
        internally.

        (WebCore::CSSPrimitiveValue::fontFamily):
        Add a getter to retrieve the internal CSSFontFamily object if the
        primitive type is CSS_FONT_FAMILY.

        * css/CSSPropertyNames.in:
        Treat 'font' as a regular shorthand property. Specify its longhand
        properties so that makeprop.pl can generate the shorthand code for
        us. Also demote 'font' to being a low-priority property as it is
        now always expanded during parsing.

        * css/CSSValuePool.cpp:
        (WebCore::CSSValuePool::createFontFamilyValue):
        * css/CSSValuePool.h:
        * css/StyleBuilderCustom.h:
        (WebCore::StyleBuilderCustom::applyValueFontFamily):
        - Update the 'font-family' value setter in the StyleBuilder to reflect
        the changes in the CSS parser. The CSSPrimitiveValues in the list now
        have CSS_FONT_FAMILY type instead of CSS_STRING.
        - We also set the 'isGenericFamily' flag if the font-family was expanded
          from a system font ID (e.g. caption). The 'isGenericFamily' flag is
          used later on to property set the 'isSpecifiedFont' flag on the
          FontDescription object. If we don't do this, system font values will
          be treated as specified fonts, which means that we will no longer use
          the 'use backslash as Yen sign' hack for those. This is covered by the
          following layout tests:
          - fast/text/backslash-to-yen-sign-euc.html
          - editing/selection/find-yensign-and-backslash.html

        (WebCore::StyleBuilderCustom::applyInitialFont): Deleted.
        (WebCore::StyleBuilderCustom::applyInheritFont): Deleted.
        (WebCore::StyleBuilderCustom::applyValueFont): Deleted.
        Remove StyleBuilder code dealing with the 'font' property. Now that
        the 'font' property is always expanded during parsing, this code can
        never be reached.

        * css/StylePropertyShorthand.cpp:
        (WebCore::isExpandedShorthand):
        Stop returning false for 'font' as it is now expanded during parsing
        as well. We should probably consider renaming this method to something
        else now that all shorthands are expanded, maybe isCSSShorthand() or
        isShorthandProperty().

        (WebCore::fontShorthand): Deleted.
        * css/StylePropertyShorthand.h:
        (WebCore::matchingCustomShorthandsForLonghand): Deleted.
        Remove custom shorthand code for the 'font' property as it is now
        generated by makeprop.pl, like other shorthands.

        * css/StyleResolver.cpp:
        (WebCore::StyleResolver::applyFont): Deleted.
        This is unused now that the StyleBuilder code for 'font' has been
        removed.

        * css/makeprop.pl:
        Remove custom shorthand code for 'font' as it no longer requires any
        special handling.

        This is an adaptation of work Rob Buis did in Blink:

            http://src.chromium.org/viewvc/blink?view=revision&revision=173258

        The goal here is to reduce use of SVGElementInstance since we are going to
        remove it. The tests Rob added to Blink (which I believe I improved a bit here)
        meant we had to fix quite a few bugs in the implementation of the width/height
        logic rather than just moving it. Even so, this could use even more test coverage
        since there is separate logic for <symbol> and <svg>, three different code paths
        (animation/attribute setting, initial creation, and one other), and also
        distinct issues for attributes not set at all, attributes set to values that
        can't be parsed, and attributes set with different units.

        width or height property are either not set or not successfully parsed. Without
        this change, one of the SVG tests starts failing.

        * svg/SVGUseElement.cpp:
        (WebCore::updateWidthAndHeight): Added. The tricky part here is that we have
        to copy width and height attributes only if they were successfully parsed, and
        also we need to copy the current animating values, not the original attribute
        strings. Kind of messy, but I wanted to adapt Rob's solution for the time being,
        rather than inventing something new.
        (WebCore::SVGUseElement::svgAttributeChanged): Call updateWidthAndHeight.
        This is used both when actual attribute changes occur and also when animation
        changes the current value.
        (WebCore::SVGUseElement::buildShadowAndInstanceTree): Call updateWidthAndHeight.
        This is used when the shadow elements are first created.
        (WebCore::SVGUseElement::expandUseElementsInShadowTree): Call updateWidthAndHeight.
        This was in Rob's patch, but I am not sure we have sufficient test coverage.

        Implement system fonts FontDescription caching at RenderTheme level
        https://bugs.webkit.org/show_bug.cgi?id=140840

        Reviewed by Andreas Kling.

        Implement system fonts FontDescription caching at RenderTheme level
        instead of duplicating the logic in its subclasses for each platform.
        This reduces code / logic duplication and reduces the amount of
        platform-specific code. This will also make the refactoring at
        Bug 140577 a lot easier.

        The caching logic remains in RenderThemeIOS class for iOS because:
        - It supports different system font values than all other platforms
        - It requires cache invalidation in some cases while other platforms
          do not.

        This patch is inspired by the following Blink revision:

        SVGNames.cpp and HTMLNames.cpp are sometimes malformed
        https://bugs.webkit.org/show_bug.cgi?id=140784
        <rdar://problem/17701233>

        Reviewed by David Kilzer.

        Due to bad rules in DerivedSources.make, make_names.pl was called
        several times with the same arguments during build. This is because
        SVG/HTML/MathML each had several targets associated to the same
        command. This would cause the command (make_names.pl) to be called
        once per target. However, make_names.pl only needs to be executed
        once to generate all of the files currently marked as target.

        Calling make_names.pl several times for the same files is not only
        wasteful, but it can also lead to malformed generated files if the
        scripts instances are executed in parallel as they will read / write
        from / to the same files.

        This patch uses INTERMEDIATE targets instead so that we can still
        indicate which files are generated by make_names.pl but only run
        the script once.

        This is a similar fix as for Bug 140756. There may several other
        similar issues in DerivedSources.make but this patch focuses on
        make_names.pl. I will take care of other in follow-ups if needed.

        <rdar://problem/19467942>

        Reviewed by David Kilzer.

        The makeprop.pl script was called 4 times (instead of once) during
        build due to a bad Makefile rule in DerivedSources.make. makeprop.pl
        had 4 associated targets and thus was called 4 times (with the same
        parameter). Calling it once is sufficient to generate all 4 files
        that were marked as target. This patch uses an INTERMEDIATE target
        instead so that we can indicate that several files are generated
        by the same command.

        I believe this may be the reason for the sporatic build failures
        that look like:
        """
        CSSPropertyNames.gperf: No keywords in input file!
        calling gperf failed: 256 at WebCore/css/makeprop.pl line 1036.
        """
        The makeprop.pl script is generating gperf's input file and calling the
        gperf executable on this file. If the script is executed several times
        in parallel, it would explain the build failures as several instances
        of makeprop.pl may be writing / reading from the same
        CSSPropertyNames.gperf file.

        [CSS Grid Layout] Skip items spanning flex tracks when sizing content based tracks
        https://bugs.webkit.org/show_bug.cgi?id=140720

        Reviewed by David Hyatt.

        Section "11.5. Resolve Intrinsic Track Sizes" of the specs forces
        us to ignore items spanning tracks with flex sizing functions when
        resolving the content-based track sizing functions. Items with
        span < 2 are not affected by this rule (as they will belong to a
        single track). This way the algorithm ensures that min-content and
        max-content restrictions are fulfilled before distributing the

        The problem is that it was incorrectly implemented, it has two
        important bugs. First one is that the hash table that collects
        items is regenerated after processing each track, so it's actually
        doing nothing. Secondly we're only sorting the items on each

        Handle the transition on any character as a separate type of transition
        https://bugs.webkit.org/show_bug.cgi?id=140711

        Reviewed by Andreas Kling.

        Instead of considering the universal transition as 127 transitions, it is now
        handled as a separate type of transition.

        The goal is to reduce the number of exit edge to consider for each node. Instead
        of having 127 for any partition containing one universal transition, we have
        as few exit edges as necessary + one universal transition.

        In the NFA, the universal transition is stored directly on NFANode in a new
        HashSet (transitionsOnAnyCharacter).
        The target nodes are made exclusive between "transitionsOnAnyCharacter" and "transitions"
        by construction. That is not strictly needed but it simplify debugging at the moment.

        When converting a NFA to a DFA, we first find all the node that transition on any character.
        Then, when we iterate over "real" transition, we also augment that set with the set on
        any character.

        When creating the DFA node, we first consider each "real" transition, then we have a single
        "fallback" transition for any character that has not been handled yet.

        When matching, we first search for any real transition. If there is none but a fallback exists,
        we take the fallback.

        REGRESSION(r178180): Membuster regressed ~4%

        Reviewed by Andreas Kling.

        After r178180 we keep system fallback fonts that are used on glyph pages alive.
        Previously we would traverse the glyph pages and remove entries referencing system fallbacks.

        first-letter pseudo-element from ancestors is not being ignored in grids and flexboxes
        https://bugs.webkit.org/show_bug.cgi?id=138424

        Reviewed by Benjamin Poulain.

        Source/WebCore:

        According to the grid and flexbox specs:
        "::first-letter pseudo-element do not apply to grid/flex containers".
        http://dev.w3.org/csswg/css-grid/#grid-containers
        http://dev.w3.org/csswg/css-flexbox/#flex-containers

        Check also the CSS WG mailing list discussion:
        http://lists.w3.org/Archives/Public/www-style/2014Dec/0305.html

        This was almost working right, except in the case that an ancestor was
        setting the ::first-letter pseudo-element.

        Added a few more cases to the current tests in order to check this
        behavior.
        Also created some new tests to increase coverage

        Simplify DiagnosticLoggingClient call sites
        https://bugs.webkit.org/show_bug.cgi?id=140701

        Reviewed by Andreas Kling.

        Simplify DiagnosticLoggingClient call sites by:
        - Moving the Settings::diagnosticLoggingEnabled() check inside the
          MainFrame::diagnosticLoggingClient() getter.
        - Having MainFrame::diagnosticLoggingClient() return a reference
          instead of a pointer (returning a dummy client if necessary).

        Otherwise, each call site needs to both check the setting and do a
        null-check on the client which is a bit annoying.

        Fast path for casting JSValue to JSDocument*.
        <https://webkit.org/b/134655>

        Add a custom JSType bit for JSDocument so we can quickly cast to it
        from JSValue in the DocumentPrototype functions. This removes a bunch
        of grunt work and branches from common functions like getElementById.

        Also removed GetCastingHelperForBaseObject and replace it with
        simple jsCasts since we don't need dynamic type checks for the base.

        [CSS Grid Layout] Wrong arguments passed to computeNormalizedFractionBreadth
        https://bugs.webkit.org/show_bug.cgi?id=139058

        Reviewed by Andreas Kling.

        The method RenderGrid::computeNormalizedFractionBreadth() is
        supposed to get as fourth argument either the grid element's
        content box size or the max-size of a particular grid item. For
        the former we were incorrectly passing the free space after
        distributing the available space to tracks.

        Apart from that, that method has a bug in its implementation. As
        we were using the free space instead of the grid element's content
        box size, we didn't have to subtract the usedBreadth of grid
        tracks from the passed in value. That did not work for the case of
        the caller passing the max-size of a particular item.

        LayoutState and subtree layout code should use RenderElement.
        <https://webkit.org/b/126878>

        Subtree layout will never begin at a RenderText, so tighten up
        the code to operate on RenderElements instead of RenderObjects.

        Layers need to be already updated before we call adjustViewSize

        Defer painting operations until we have finished layout. This
        has a couple of benefits:
        (1) We do not attempt to modify render layers during layout.
        (2) In WK1 we do not attempt to paint during layout.

        Add a new virtual predicate to ScrollView indicating when we are in
        layout so that calls to setContentsSize do not attempt
        to adjust scrollbars.

        Modify FrameView to set its ScrollView state to block paint
        operations during layout. Also add a post-layout handler to
        complete the scrollbar updates after layout is finished.

        Web Inspector: highlight data for overlay should use protocol type builders

        As a first step towards cleaning up the inspector overlay, convert highlight

        This change paves the way towards using inspector protocol commands and events

        Fixes an issue where a web page would fail to load in iOS WebKit2 built with the public iOS SDK
        because NSURLConnection callbacks were always being scheduled on the main thread.

        Currently we always schedule NSURLConnection callbacks to occur on the WebThread or the main
        thread depending on whether the WebThread was started. In iOS WebKit2, the callbacks were
        always being scheduled on the main thread regardless of whether we were using the NetworkProcess
        (since the WebThread is only started when using WebKit1). This led to an assertion failure.
        Instead we want to schedule callbacks to an NSOperationsQueue queue when using WebKit2 with the
        NetworkProcess (i.e. ResourceHandleClient::usesAsyncCallbacks() is true), on the main thread when
        using WebKit2 without the NetworkProcess and on the WebThread when using WebKit1.

        Add the alternative syntax for CSS Selector's descendant combinator (">>")
        https://bugs.webkit.org/show_bug.cgi?id=140525

        Reviewed by Antti Koivisto.

        The latest Selector spec introduces the combinator ">>" as an alias for the descendant
        relation: http://dev.w3.org/csswg/selectors-4/#descendant-combinators

        This patch implements that combinator as an alias of the existing one. For CSSOM's selector
        serialization, I use one bit of CSSSelector to store if that alternative syntax was used.

        Generate StylePropertyShorthand.* from CSSPropertyNames.in

        Reviewed by Darin Adler.

        Add initial support for having makeprop.pl generate most of
        StylePropertyShorthand.* from CSSPropertyNames.in.

        This patch replaces [Shorthand] parameter in CSSPropertyNames.in by a
        more descriptive [Longhands=property1|property2|...] parameter. With
        this information, makeprop.pl is now able to generate the
        StylePropertyShorthand factories for all CSS shorthand properties
        in a new StylePropertyShorthandFunctions.h header.

        The switches in StylePropertyShorthand.cpp could also be generated
        but this will be taken care of in follow-up patches to reduce patch
        size.

        Some improvements to RuleSet shrinking.

        Reviewed by Antti Koivisto.

        Give an inline capacity (1) to the RuleData Vectors in RuleSet.
        The vast majority of Vectors have only a single entry, and this
        avoids having to allocate a separate Vector backing store for them.

        Also make sure to shrink some Vectors that we weren't already,
        like those in RuleFeatureSet.

        Element appears correctly but does not receive event with a large translation.
        https://bugs.webkit.org/show_bug.cgi?id=139815

        Reviewed by Simon Fraser.

        When the hit point gets translated beyond the min/max value of LayoutRect (infiniteRect()),
        we fail to find the corresponding layer.
        When there's no clipping on a layer, we use min/max values to represent infiniteness.
        However it does not work well across types. With IntPoint(hittest) we can address a point that's outside
        of LayoutRect's boundary(clipping).
        This patch addresses the immediate issue of not being able to hittest transformed layers properly. 
        Fixing the representation of infiniteness is tracked here: webkit.org/b/140533

        The bug was caused by adjustDirectionalityIfNeededAfterChildrenChanged always traversing children to

        Fixed the bug by removing this code. This code was no-op prior to being refactored in r154957 since

        has a couple of benefits:
        (1) We do not attempt to modify render layers during layout.
        (2) In WK1 we do not attempt to paint during layout.

        Add a new virtual predicate to ScrollView indicating when we are in
        layout so that calls to setContentsSize do not attempt
        to adjust scrollbars.

        Modify FrameView to set its ScrollView state to block drawing
        scrollbar updates during layout. Also add a post-layout

        When building the NFA of the global disjunction, share the prefix subgraph of existing subpatterns
        https://bugs.webkit.org/show_bug.cgi?id=140465

        Reviewed by Andreas Kling.

        This patch updates the parser to produce smaller graphs when multiple patterns
        of the rule list share a common prefix.

        Previously, GraphBuilder would generate subgraph in place of each parsed
        atom. We now only create subgraph if an atom does not appear in the prefix tree.

        We accumulate the parsing information into small uint16_t named TrivialAtom.
        When generating the subgraph for an new atom, we first check if the prefix tree already
        has a corresponding subgraph for that atom. If it does, we do not generate anything and we extend the existing
        graph. If there is no existing prefix, we create the subgraph and extend the prefix tree.

        Sharing prefix subtrees slows down the subtree generation a bit but the resulting graph is much
        simpler for many kind of inputs.

        Graphics corruption after Find on some pages
        https://bugs.webkit.org/show_bug.cgi?id=140489

        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.

        REGRESSION (r154769): Wrong <title> taken as a tooltip for SVG element.
        https://bugs.webkit.org/show_bug.cgi?id=139690.

        Reviewed by Daniel Bates.

        Before r154769, we were calling Traversal<SVGTitleElement>::firstWithin(), which returns
        the first immediate SVGTitleElement child. In r154769, Traversal<SVGTitleElement>::firstWithin()
        was replaced by descendantsOfType<SVGTitleElement> which returns all descendants SVGTitleElements.
        Then we were returning the first element of these descendants, which may not be an immediate
        child of the element, as the title of the SVGElement. This was the reason of this bug. The
        fix is to use childrenOfType<SVGTitleElement>() instead, which returns the immediate SVGTitleElement
        children of an SVGElement.

        Also we were not following exactly the specs for the rootmost SVG element's title value.
        According to the W3C specs, for stand-alone SVG documents only, the rootmost SVG element
        should not return a title. But we were not returning a title for the rootmost SVG element
        always. The fix is to return a empty title for the rootmost SVG element only if topDocument()
        of the element isSVGDocument().
        
        NOTE: The main SVG specs http://www.w3.org/TR/SVG/interact.html#hit-testing (W3C Recommendation
        16 August 2011) and http://www.w3.org/TR/SVG/struct.html#DescriptionAndTitleElements (W3C
        Recommendation 16 August 2011) do not say how the tooltip of an SVG element is calculated. But
        the SVG tiny specs http://www.w3.org/TR/SVGTiny12/struct.html#uiTitleDescBehavior (W3C
        Recommendation 22 December 2008) however explains well the tooltip calculation for the embedded
        and the stand-alone SVG cases. And it seems this what we should rely on.

        Do not create new set for every sub-operation when converting a NFA to DFA
        https://bugs.webkit.org/show_bug.cgi?id=140380

        Reviewed by Andreas Kling.

        This is the first step toward making the NFA-to-DFA conversion more scalable: instead
        of creating new sets for each step of the algorithm, we use two kinds of sets
        and never do any copy.

        The first new tool to do that is UniqueNodeIdSetImpl. It represents a set of NFA state corresponding to a DFA
        state. It is unique per DFA state.

        HashableNodeIdSet is a helper tool storing a UniqueNodeIdSetImpl.

        The creation of new sets now goes like this:
        1) Get a NodeIdSet for each possible transition.
        2) For each transition:
           2a) Extend the NodeIdSet in place with its epsilon closure.
           2b) Get the UniqueNodeIdSetImpl corresponding to the new set we discovered.
           2c) If the UniqueNodeIdSetImpl is new, queue it for processing.

        Null-deref crash when seeking immediately before looping.
        https://bugs.webkit.org/show_bug.cgi?id=140394

        Reviewed by Eric Carlson.

        It is possible for finishSeek() to be called when a seek() has caused a pending seek task
        to be scheduled, but before that pending seek task is run. In this case, if a seek request
        is issued, the existing pending seek task will not be cancelled, which will cause a crash
        when the pending seek task is run.

        When checking whether an existing seek task needs to be cancelled, check the actual timer,
        rather than the m_seeking boolean, so that this case is covered.

        Filters and clipping were not taking columns into

        defaultPlaybackRate not respected when set before source is loaded
        https://bugs.webkit.org/show_bug.cgi?id=140282

        Reviewed by Eric Carlson.

        Test: media/video-defaultplaybackrate-before-load.html

        When the HTMLMediaElement is notified that the media player's rate has changed, it asks
        for the rate from MediaPlayer. However, MediaPlayer never requests the playback rate
        from the underlying MediaPlayerPrivate; it just returns the last rate which was set, or
        1 if no rate was set. HTMLMediaElement then sets its playbackRate to the returned
        value. So the end result is that the value from defaultPlaybackRate is overwritten by
        the default value of 1 in MediaPlayer.

        Rather than caching the requested rate in MediaPlayer, cache the value reported by
        MediaPlayer inside HTMLMediaElement. And instead of returning the reported playback
        rate from HTMLMediaElement.playbackRate, just return the last value set. The reported
        value is still used for estimating the current time during playback.

        Add MediaPlayerPrivate interface method to return the current playback rate.

        If ENABLE(SVG_OTF_CONVERTER) is defined, use the converter. It can be defined at the same

        defaultPlaybackRate not respected when set before source is loaded
        https://bugs.webkit.org/show_bug.cgi?id=140282

        Reviewed by Eric Carlson.

        Test: media/video-defaultplaybackrate-before-load.html

        When the HTMLMediaElement is notified that the media player's rate has changed, it asks
        for the rate from MediaPlayer. However, MediaPlayer never requests the playback rate
        from the underlying MediaPlayerPrivate; it just returns the last rate which was set, or
        1 if no rate was set. HTMLMediaElement then sets its playbackRate to the returned
        value. So the end result is that the value from defaultPlaybackRate is overwritten by
        the default value of 1 in MediaPlayer.

        Rather than caching the requested rate in MediaPlayer, cache the value reported by
        MediaPlayer inside HTMLMediaElement. And instead of returning the reported playback
        rate from HTMLMediaElement.playbackRate, just return the last value set. The reported
        value is still used for estimating the current time during playback.

        Add MediaPlayerPrivate interface method to return the current playback rate.

        constantly setting it when cycling through states, switched style to use
        early return/goto rather than lots of else statements, took out unneeded
        braces now that BEGIN/END_STATE handles the braces, collapsed upper and
        lower case letter handling in many states, changed lookAhead call sites to
        use the new advancePast function instead.
        (WebCore::HTMLTokenizer::updateStateFor): Set m_state directly instead of
        calling a setstate function.
        (WebCore::HTMLTokenizer::appendToTemporaryBuffer): Moved here from header.
        (WebCore::HTMLTokenizer::temporaryBufferIs): Changed argument type to
        a literal instead of a WTF::String.
        (WebCore::HTMLTokenizer::appendToPossibleEndTag): Renamed and changed type
        to be a UChar instead of LChar, although all characters will be ASCII.
        (WebCore::HTMLTokenizer::isAppropriateEndTag): Marked const, and changed
        type from size_t to unsigned.

        * html/parser/HTMLTokenizer.h: Changed interface of nextToken so it returns
        a TokenPtr so code doesn't have to understand special rules about when to
        work with an HTMLToken and when to clear it. Made most functions private,
        and made the State enum private as well. Replaced the state and setState
        functions with more specific functions for the few states we need to deal
        with outside the class. Moved function bodies outside the class definition
        so it's easier to read the class definition.

        pointer for the preprocessor.

        general purpose prepend function. Also fixed assertions to not use the strangely

        (WebCore::SegmentedString::append): Ditto.
        (WebCore::SegmentedString::advancePastNonNewlines): Renamed from advance, since
        the function only works for non-newlines.
        (WebCore::SegmentedString::currentColumn): Got rid of unneeded local variable.

        renamed local variable "cc" to character. Changed code to use helpers like
        isASCIIAlpha and toASCIIHexValue. Removed unneeded use of advanceAndASSERT,
        since we don't really need to assert the character we just extracted.

        Remove FontCachePurgePreventer
        https://bugs.webkit.org/show_bug.cgi?id=139628

        Reviewed by Anders Carlsson.

        This stack type is bug prone and invasive. A missing FontCachePurgePreventer in a code that touches fonts is always
        a hard-to-detect bug and there are many places that need it. Instead purge the font cache on top of the runloop.

        The purge timer could in principle fire in a nested runloop. However we should never have unreferenced
        SimpleFontData objects in the stack in such case (GlyphData objects don't currently ref the font) because those
        only occur during layout and painting. Layout and painting can't trigger a nested runloops as there would be
        bigger problems.

        Purging may also be triggered synchronously by a memory notification. That case won't have any GlyphDatas in the stack either.

        Get rid of legacy StyleBuilder switch in StyleResolver.cpp now that most

        properties or other properties that do not require any handling in the

        To achieve this, this patch introduces 2 parameters in
        CSSPropertyNames.in:
        - SkipBuilder: Indicates that no StyleBuilder code should be generated
          for this property.
        - Shorthand: Indicates that this is a shorthand property, which therefore
          does not use the StyleBuilder. makeprop.pl will merely generate

        [Cocoa] Make decoded image data purgeable ASAP.
        <https://webkit.org/b/140298>

        Reviewed by Antti Koivisto.

        Mark decoded images as "transient" which makes CoreGraphics mark
        the backing stores as purgeable shortly after they're used.

        The decoded representation will remain in CoreGraphics's caches
        indefinitely unless the kernel gets starved and needs the pages.

        Most resources will now reach a state where the encoded data is
        mmap'ed from disk cache (once the entire resource is downloaded)
        and the decoded data is purgeable.

        This also has the side effect of making the MemoryCache more
        palatial since the decoded data cost can be deducted for images,
        allowing us to cache more resources.

        Note that the worst case for this new behavior would be something
        like hovering below 100% memory utilization and constantly having
        to drop and re-decode images. While churny, it still beats
        crashing the process, plus there's tiling to remove many of the
        reasons we'd need the decoded data.

        This is crashing because AppKit is checking if certain method names like "accessibilityTitle" exist,
        and then it bypasses accessibilityAttributeValue: to call directly into those methods.

        That bypasses are safety checks. I think a safe way to avoid this is rename our methods.

        No new tests, problem only occurs when triggered through AppKit.

        After r178166, ANGLE's EGL/GLES/GLES2 headers are included before the

        ASSERTION FAILED: !valueWithCalculation.calculation() in WebCore::CSSParser::validateCalculationUnit
        https://bugs.webkit.org/show_bug.cgi?id=140251

        Reviewed by Darin Adler.

        Using a calculated value for text-shadow's blur-radius was hitting an
        assertion in CSSParser::validateCalculationUnit() because validUnit()
        is called twice, first with 'FLength' unit, then more stricly with
        'FLength|FNonNeg' if parsing the blur-radius as it cannot be negative
        as per the specification:
        - http://dev.w3.org/csswg/css-text-decor-3/#text-shadow-property
        - http://dev.w3.org/csswg/css-backgrounds-3/#shadow

        On the second call, the ValueWithCalculation's m_calculation member
        was already initialized and the code did not handle this. This patch
        updates validateCalculationUnit() to teach it to reuse the previously
        parsed calculation in this case. All it needs to do is to update the
        existing CSSCalcValue's range to allow negative values or not.

        When writing the layout test for this, I also noticed that the CSS
        parser was not rejecting negative calculated values for blur-radius
        (only negative non-calculated ones). This is because
        validateCalculationUnit() was ignoring FNonNeg if the calculated
        value is a Length. This patch also addresses the issue.

        (WebCore::CSSCalcValue::setPermittedValueRange):
        Add a setter to update the CSSCalculationValue's permitted value range

        (WebCore::CSSParser::validateCalculationUnit):
        - Teach the code to reuse the previously parsed calculation value.

        Each of those mechanism implies messaging the UIProcess, executing some code
        calling back to the WebProcess, then actually load the resource.
        All this back and forth introduces delays before we actually load resources.

        Since the set of actions is done per site is actually simple and limited,
        it may be possible to do everything in WebCore and shortcut the defered loading.

        This patch provides the starting point for this idea. The "rules" (currently just blocking)
        are be passed to WebCore in a JSON format. In WebCore, we create a state
        machine to match the rules and we execute the action when the state machine tells
        us to.

        Make better use of the stack when compiling selectors
        https://bugs.webkit.org/show_bug.cgi?id=139615
        rdar://problem/19226482

        Reviewed by Andreas Kling.

        Selectors used to be only on one level. To avoid memory allocations, we were allocating
        a lot of stack upfront and we were using that to create all the intermediary objects
        used by the code generator.

        Then, selectors became multilevel. We now support arbitrary nesting of selector lists.

        We did not adapt any of the structures and the creation of the intermediary object is recursive.
        This resulted in over 1k of stack allocation at every level, quickly accumulating to unreasonable
        numbers.

        This patch fixes this problem by making each stack frame of the recursion much lighter.
        We no longer allocate the big objects (SelectorFragment and SelectorFragmentList) on the stack.

        In each case where we would have used a Stack allocated SelectorFragment or SelectorFragmentList,
        we now allocate the memory directly into the target vector.

        In the cases where the object should not be on the vector, we simply remove it. Those are uncommon
        cases so that should not be too bad.

        * cssjit/SelectorCompiler.cpp:
        SelectorFragmentList is also used for nested lists. Keeping 32 SelectorFragment preallocated
        for each nested list is way too big.

        (WebCore::SelectorCompiler::addPseudoClassType):
        There are three cases of nested selector lists supported by the compiler: :matches(), :not()
        and :nth-child(). For those 3 cases, use the target vector memory instead of the stack.

        I changed the handling of :nth-child(An+B of selectorList) to not generate empty filters.
        With that we can generalize the assertion to generateElementMatchesSelectorList() and simplify
        the flow of selector lists a bit.

        Remove the concept of "retained" font
        https://bugs.webkit.org/show_bug.cgi?id=140246

        Reviewed by Darin Adler.

        FontCache currently maintains a secondary refcount for SimpleFontDatas. This is used to decide whether
        a font is considered inactive and is eligible for purging. This is confusing and complex.

        The new scheme in this patch considers fonts in font cache inactive if their refcount is 1 (they are
        owned by the cache only). This simplifies the code and gives similar behavior. Types that "retained" the
        font this way always also ref it.

        We also avoid unnecessarily removing fonts that wouldn't get deleted from the cache.

        Also modernized some names and code.

        [GTK] Seperate updateBackingStore from flushCompositingState.
        https://bugs.webkit.org/show_bug.cgi?id=136887

        Reviewed by Žan Doberšek.

        When LayerTreeHostGtk flushes pending layer changes, it updates backing
        stores using same loop. This makes requesting layer flush during
        flushing in certain condition which causes a assertion failure.

        Animated GIF's animations are drived by the painting cycle,
        GraphicsLayerTextureMapper::updateBackingStoreIfNeeded would request
        scheduleLayerFlush during flushing layers, if animated GIF needs to
        advance its frame immediately. It doesn't mean the advanced frame should
        be painted in this painting phase. This frame advancing happens after
        painting a current frame to the backing store. It means the advanced
        frame should be painted ASAP without using its frame timer.

        This patch seperates updateBackingStore from flushCompositingState
        to avoid above behavior.

        Also fix the support for angles in calc().
        CSSPrimitiveValue::computeDegrees() was accessing m_primitiveUnitType
        member directly, which would be incorrect in the case of calculated
        values. This patch switches to calling CSSPrimitiveValue::primitiveType()
        which handles calculated values.

        This function has a bug when it goes through the fast decoding code path. After copying

        is copied as is from the source to the destination even if it is non ASCII byte. This
        causes the decoded bytes to be incorrect. The fix is to ensure that the current byte
        is still ASCII after exiting the fast decoding code path.

        Web Inspector: purge PassRefPtr from Inspector code and use Ref for typed and untyped protocol objects
        https://bugs.webkit.org/show_bug.cgi?id=140053

        Reviewed by Andreas Kling.

        This patch replaces uses of PassRefPtr with uses of RefPtr&& and WTF::move() in code
        related to Web Inspector. It also converts many uses of RefPtr to Ref where
        references are always non-null. These two refactorings have been combined since
        they tend to require similar changes to the code.

        No new tests, no behavior changed.

        [CSS Shapes] Content does not wrap with overflow: hidden and reference box different from margin-box
        https://bugs.webkit.org/show_bug.cgi?id=138139

        Reviewed by David Hyatt.

        To determine how much an box needs to shink to avoid a float, the code
        was only taking into account the first line of the box. This doesn't
        work when the float has a shape, as it can make it seem like there is
        more space on the line than there actually is. This patch changes the
        calculations to take into account the entire height of the box that
        needs to be shrunk, and thus computes the correct amount of space
        available.

        Web Inspector: purge PassRefPtr from Inspector code and use Ref for typed and untyped protocol objects
        https://bugs.webkit.org/show_bug.cgi?id=140053

        Reviewed by Andreas Kling.

        This patch replaces uses of PassRefPtr with uses of RefPtr&& and WTF::move() in code
        related to Web Inspector. It also converts many uses of RefPtr to Ref where
        references are always non-null. These two refactorings have been combined since
        they tend to require similar changes to the code.

        No new tests, no behavior changed.

        https://bugs.webkit.org/show_bug.cgi?id=139929

        Reviewed by Darin Adler.

        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.

        Only throttle DOM timers if they change CSS properties that cannot cause non-descendant elements to become visible
        https://bugs.webkit.org/show_bug.cgi?id=140142

        Reviewed by Darin Adler.

        Only throttle DOM timers if they change CSS properties that cannot cause
        non-descendant elements to become visible. For example, a DOM timer may
        change the height of an element that is outside the viewport. However,
        changing its height may causes elements inside the viewport to move. As
        such, we should NOT throttle such DOM timer.

        With this patch, we only mark a repeating timer as candidate for
        throttling if it is updating one of the following CSS properties:
        left, right, top, bottom, webkit-transform, opacity.

        Do not attempt to revalidate cached main resource on back/forward navigation
        https://bugs.webkit.org/show_bug.cgi?id=139263

        Reviewed by Darin Adler.

        Do not attempt to revalidate cached main resource on back/forward
        navigation, as allowed by RFC2616 & newer RFC7234 which distinguish
        history mechanisms and caches, stating:

           The freshness model (Section 4.2) does not necessarily apply to
           history mechanisms.  That is, a history mechanism can display a
           previous representation even if it has expired.

        Previously, we would bypass revalidation on back/forward navigation
        only for sub-resources. This patch extends this policy to the main
        resource as well.

        This behavior is also consistent with IE10+ and Chrome. It makes it more
        likely we return cached content to the user on back/forward navigation
        and avoids making network requests in this case.

        * loader/cache/CachedResource.cpp:
        (WebCore::CachedResource::redirectChainAllowsReuse):
        Add a "ReuseExpiredRedirectionOrNot" flag argument because in the case
        of an HistoryBuffer navigation, we don't mind reuse an expired
        redirection. However, we still need to make sure that the redirection
        is actually cached before reusing it.

        * loader/cache/CachedResource.h:
        * loader/cache/CachedResourceLoader.cpp:
        (WebCore::CachedResourceLoader::determineRevalidationPolicy):
        - Do the redirectChainAllowsReuse() check *before* checking if the cache
          policy is CachePolicyHistoryBuffer. This is needed because
          redirectChainAllowsReuse() will return false if the redirection is not
          cached. Loading from the cache in this case will cause us to load the
          wrong resource (the one before the redirection). This case is covered
          by http/tests/navigation/redirect-on-reload-updates-history-item.html.
        - Do not use the cached main resource if it has "cache-control: no-store",
          even if it is a history navigation (cachePolicy is
          CachePolicyHistoryBuffer). This maintains the previous behavior, and
          some layout tests rely on this. We now have to be explicit about it
          because cachePolicy() can now return CachePolicyHistoryBuffer for the
          main resource (not just sub-resources). This difference in behavior
          on history navigation for the main resource and sub-resources is not
          great. However, I chose to maintain this pre-existing behavior in this
          patch to do one behavior change at a time. We can harmonize this later.

        Previously, the order was not an issue because the main resource was
        always revalidated on back/forward navigation.

        (WebCore::CachedResourceLoader::cachePolicy):
        Return CachePolicyHistoryBuffer for the main resource in case of
        history navigation, instead of CachePolicyVerify so that we don't
        attempt to revalidate.

        A repeating DOM timer changing the style of an element that has
        overflowing content that is visible would get throttled in the
        case where the overflowing content has its own layer. This is
        because the repaint rect returned by
        RenderObject::absoluteClippedOverflowRect() does not take into
        consideration descendants with their own self-painting layer when
        accounting for the overflow.

        Until I can find a relatively cheap way of computing the overflow
        in this case, this patch takes the conservative approach and
        assumes we may repaint inside the viewport if the element does not
        have a layer or if any of its descendants has its own layer.

        This patch also renames isInsideViewport() function to
        mayCauseRepaintInsideViewport() for clarity.

        Using calc() in repeat() for -webkit-grid-template-rows does not work
        https://bugs.webkit.org/show_bug.cgi?id=140094

        Reviewed by Darin Adler.

        Using calc() in repeat() for -webkit-grid-template-rows was not working
        because the CSS parser was not handling this case properly. This patch
        addresses the issue.

        Test: fast/css-grid-layout/grid-repeat-calc.html

        * css/CSSCalculationValue.h:
        (WebCore::CSSCalcValue::isPositive):
        Add isPositive() method as it is needed by
        CSSParser::validateCalculationUnit().

        * css/CSSParser.cpp:
        (WebCore::CSSParser::validateCalculationUnit):
        Add support for FPositiveInteger, similarly to what was done in
        validateUnit(). This would cause us to consider calc(1 + 1) as invalid
        if a FPositiveInteger was requested.

        (WebCore::CSSParser::parseGridTrackRepeatFunction):
        Do not access fValue directly and call parsedDouble() instead as it
        correctly handles calculation values.

        Web Inspector: pass parameters to inspector instrumentation by reference where possible
        https://bugs.webkit.org/show_bug.cgi?id=139981

        Reviewed by Andreas Kling.

        Clean up inspector instrumentation entry points throughout WebCore. In particular, make
        parameters pass-by-reference if they are not nullable. Also standardize quirky parameter
        orders and do other small cleanups in InspectorInstrumentation and at callsites.

        Inspector agents still take the pertinent parameters by pointer even when they could be
        passed by reference. This will be addressed in a follow-up change.

        No new tests, no behavior changed.

        [Mac] Cannot scroll when a non-scrollable iframe is contained inside a scrollable iframe
        https://bugs.webkit.org/show_bug.cgi?id=139914
        <rdar://problem/18750910>

        Reviewed by Darin Adler.

        Tests: platform/mac/fast/scrolling/scroll-nested-iframe.html

        The latching logic was breaking down when a non-scrollable iframe was the closest target of
        a wheel event. EventHandler would latch to the enclosing scrollable region (in this case, the
        non-scrollable iframe) and would eat scroll events, preventing anything from working.
        
        The fix is as follows:
        1. Modify the logic to understand a stack of latched states, so that we can discared 'invalid'
           latched states as we discover them.
        2. Revise the latching logic so that it understands the case where the 'latched' node for wheel
           events is in a parent frame of the current wheel event target. For example, when the mouse is over
           an element in an unscrollable iframe that is contained within a scrollable iframe. We should
           be latched to the scrollable iframe so events go to the right place.

        * page/EventHandler.cpp:
        (WebCore::EventHandler::handleWheelEvent): Update to call new 'stack' versions of latch
        state methods.

        (WebCore::EventHandler::platformPrepareForWheelEvents): Update to use new 'stack' style latch
        methods. Also, if we are latched to a frame that contains the frame we are currently evaluating,
        don't replace the current event target with the latched targets because (1) they will be processed
        in the enclosing scope when we leave this routine, and (2) if we do change targets to the latched
        elements we create an infinite loop.
        (WebCore::EventHandler::platformCompleteWheelEvent): We want to mark the element as having started
        at the scroll limit regardless of what the wheel event handler returns as its success state.
        (WebCore::EventHandler::platformCompletePlatformWidgetWheelEvent): Revise to handle the new
        stack-based latching methods.

        [GStreamer] Disable gst-plugin-scanner if seccomp filters are enabled
        https://bugs.webkit.org/show_bug.cgi?id=140069

        Reviewed by Philippe Normand.

        If seccomp filters are enabled, any child processes we create are doomed
        if they try to use a trapped syscall: the child will receive SIGSYS and
        dump core. There appears to be no way around this.

        Fortunately, the gstreamer developers had mad prescience and provided
        us with a way to move plugin scanning in-process, so we don't need the
        helper binary at all.

        No new tests because this is covered by existing tests when seccomp
        filters are enabled.

        Remove GlyphPageTree
        https://bugs.webkit.org/show_bug.cgi?id=140015

        Reviewed by Darin Adler.

        GlyphPageTree is a global cache consisting of a tree of nodes that match SimpleFontData instances.
        The tree levels correspond to font fallback lists so that higher levels fill holes (missing glyphs)
        in the lower levels. This patch replaces it with a simpler and easier to understand caching scheme.
        In particular the goal is to have clearer ownership relations and better control over mutability.

        The new scheme looks like this:

        SimpleFontData instances cache GlyphPages for themselves. These pages are immutable after construction
        and may contain holes. This is a global cache (since SimpleFontDatas are cached globally) with the same
        lifetime as the GlyphPageTree used to have.

        FontGlyphs instances cache resolved GlyphPages for the normal font variant. These are build by traversing
        the fallback list as necessary and collecting glyphs from SimpleFontDatas. As a common case case optimization
        the page from the primary font is cached directly as long as it has the requested glyphs.
        FontGlyphs are shared between sufficiently similar Font instances so this is a shared cache as well.

        we want to reveal instead of the offset before. This is more future proof if we
        ever want to handling surrogate pairs or combining marks, rather than hard
        coding the likely incorrect rule of "go back by one code unit". Also got rid of

        and made it derive from TimerBase privately. Made the constructor explicit and
        made it take a reference rather than a pointer. Use initialization in the class
        to set up the variable, and use 0 as the special value instead of -1 since we
        now store the offset *after* the character to be revealed.

        (WebCore::RenderText::willBeDestroyed): Simplified now that the function

        values in the map are unique_ptr, so take care of deletion.
        (WebCore::RenderText::setRenderedText): Tweaked the code that calls secureText
        to make the iOS case clearer.
        (WebCore::RenderText::secureText): Rewrote the function. New version no
        longer relies on a special String::fill function; it's kind of strange that
        String had a built in concept of replacing a string with one that has the
        same length but all with a masking character. This new approach is cleaner.
        I had written a version that handles surrogate pairs and combining marks,
        but then instead wrote a comment explaining why that's not needed/helpful.
        (WebCore::RenderText::momentarilyRevealLastTypedCharacter): Added a check so
        this does nothing if we are not securing the text. Also updated logic so that
        this doesn't double hash any more and updated for other changes like using
        a reference instead of a pointer.

        * rendering/RenderText.h: Removed the unneeded isSecure function and updated
        the argument name in momentarilyRevealLastTypedCharacter since it's now the
        offset after the character, not before the character.

        Modernize coding style of HTMLTreeBuilder
        https://bugs.webkit.org/show_bug.cgi?id=140032

        Reviewed by Andreas Kling.

        Changes include:
        - Use references rather than pointers.
        - Mark data members const that are fully set up in the constructor.
        - Remove many unneeded includes and forward declarations.
        - Fix conditionals to be consistent and correct.
        - Merge some multi-line constructs into a single line.
        - Update whatwg.org URLs; not sure we should keep these, though.
        - Cut down on use of WTF_MAKE_NONCOPYABLE since for many classes it's
          impossible to copy anyway due to references, or harmless to copy.
        - Made more things private.
        - Initialize scalars in the class definition rather than each constructor.
        - Use Ref/RefPtr instead of PassRefPtr.

        * html/parser/HTMLDocumentParser.cpp:
        (WebCore::HTMLDocumentParser::HTMLDocumentParser): Pass reference rather than pointer to
        the context element.
        (WebCore::HTMLDocumentParser::detach): Removed call to HTMLTreeBuilder::detach. This work
        is instead done when the tree builder is destroyed.
        (WebCore::HTMLDocumentParser::constructTreeFromHTMLToken): Pass reference rather than pointer.

        * html/parser/HTMLTreeBuilder.cpp:
        (WebCore::uninitializedPositionValue1): Marked this inline because it's trivial. It was
        probably getting inlined already.

        [CSS Grid Layout] Remove stack from grid-auto-flow syntax
        https://bugs.webkit.org/show_bug.cgi?id=134842

        Reviewed by Sergio Villar Senin.

        "stack" mode for grid-auto-flow property has been removed from the grid
        layout spec. New syntax is:
          [ row | column ] || dense

        Modified parsing in order to adapt it to the new syntax.

        Also the current behavior relying on "stack" has been updated following
        the spec. Now it won't be possible to mimic the old "none" (or "stack")
        unless you specify manually the grid-placement properties.

        No new tests needed, updated current tests to adapt them to the new
        behavior.

        Log better using FeatureCounter why PageCache is failing due to pruned
        resources. In particular, we now distinguish if the resource was pruned
        due to:
        - Memory pressure
        - Page cache capacity reached
        - WebProcess suspended (WK2)

        [Mac] Fix nullptr dereference in EventHandler::platformPrepareForWheelEvents().

        Reviewed by Chris Dumez.

        Don't dereference 'wheelEventTarget' until we know it's non-null.
        This manifested as a crash in Node::renderBox() with some versions of LLVM.

        The compiler was free to assume that the ContainerNode* 'candidate' in
        findEnclosingScrollableContainer() would always be non-null on the first
        iteration of the loop.

        I suspect that we can get here with a null 'wheelEventTarget' during the
        rubberbanding phase of a wheel scroll; if the cursor is sitting over the
        exposed "gutter" area.

        https://bugs.webkit.org/show_bug.cgi?id=138683

        Reviewed by Darin Adler.

        This patch changes how we check fonts for equality. In particular, this patch adds a
        objectForEqualityCheck() to Cocoa's FontPlatformData, and callers should pass this object
        to CFEqual() to determine if two platform fonts are equal. This patch also migrates all
        call sites to using this function.

        I don't want to implement operator==() because there are many cases where the same font
        is compared against many others, and this solution is cleaner than caching a comparison
        object inside the font object itself.

        Form elements should match :valid and :invalid based on their associated elements
        https://bugs.webkit.org/show_bug.cgi?id=139850

        Reviewed by Darin Adler.

        In the latest HTML spec, form elements can match :valid or :invalid based
        on their associated element.

        The tricky part is that object lifetime is a mess. When elements are associated
        with forms by the parser, the form is set by the constructor of HTMLFormControlElement.
        At that point, the real object has not been initialized yet which
        makes it impossible to find its validity.

        To work around the lifetime problem, the code of HTMLFormControlElement::didChangeForm()
        uses m_willValidateInitialized and m_willValidate direclty instead
        of invoking willValidate(). That way we don't try to validate an incomplete object.

        When the object really validates, HTMLFormControlElement::setNeedsWillValidateCheck()
        takes care of updating the form.

        be released.

        Instead, introduce a new ValueWithCalculation type which wraps a
        CSSParserValue and an optional parsed calculation value. This way,
        the parsed calculation value is now associated with its CSSParserValue.
        This makes it very difficult to use a parsed calculation value for the
        wrong CSSParserValue. The API is also easier to use as developers no
        longer need to explicitly indicate if the calculation value should be
        released or not.

        Add strong typing to RefCounter interface, return value as a bool.
        https://bugs.webkit.org/show_bug.cgi?id=139776

        Reviewed by Geoff Garen.

        Currently all token vended by a RefCounter have the same type - Ref<RefCounter::Count>.
        This means there is no compile time type checking to prevent mistakes. Update the count()
        method to token<>(), templated on type used to identify the token being returned.
        Calls to token<T>() will return a result of type RefCounter::Token<T>.

        There are a few problems with the fact the counter will return you an exact count of the
        number of outstanding tokens:
          - It is desirable to only fire the callback on zero-edge changes; it is more consistent
            to do so if the value is only readable as a boolean.
          - It is desirable to provide the value as an argument to the callback, however to make
            this useful for integer values it is also necessary to indicate the direction of change
            (0->1 is often interesting where 2->1 is not).
          - There is a mismatch between the precision of returning a count, and the inherent
            imprecision of a token based mechanism, where it may be difficult to guarantee
            absolutely no unnecessary refcount churn, and thus unintentional counter values.

        This adds a heuristic to avoid a problem we have where too many objects that say they respond to press actions for accessibility.
        It results from people installing click handlers on container nodes and then lots of static text objects are "clickable" in the eyes of VoiceOver.

        What we can do is avoid this determination if the element is presentational.

        Support for this new functionality has been added in a previous patch, under issue

        the new functionality works can be found in the ChangeLog for that commit.
        The containsSVGDocument in ScrollView has been removed because it was added in the
        previous patch but is no longer required.

            Simplify by not trying to resolve fallbacks in case context sensitive (based on lang attribute etc)
            glyph selection fails. Instead just fall back to a default font. This behavior is not specified
            anywhere as far as I can see. (normal non-context sensitive fallbacks will still work fine).
            This removes the need to hackishly mutate glyph pages.

            Also fix a bug where we didn't use the specified missing glyph when context sensitive selection failed.

        Subpixel rendering: Animating HTML elements leaves trails when embedded to a subpxiel positioned iframe.

        This patch ensures that repaint rect and actual paint coordinate calculations are in sync.

        RenderWidget painting still snaps final coordinates to integral positions. We need to
        mimic the same snapping behaviour when the repaint rects are being calculated so that
        they are in sync with the final repaint rects. This is a workaround until after
        widgets get pushed to device pixel positions.

        Ruby does not preserve expansion opportunities from enclosing context

        Reviewed by David Hyatt.

        There is currently no sharing of expansion opportunity information between
        ruby bases and the text surrounding the ruby. This patch adds a bit on
        RenderText, m_contentIsKnownToFollow, which affects how expansion
        opportunities are handled at paint-time, as well as a bit on RenderRubyBase,
        m_isAfterExpansion, which affects how expansions are calculated when laying
        out a line. This patch also adds a field to RenderRubyBase which represents
        the base's starting position within a ruby. This field is necessary because
        an expansion from a line might occur at the very beginning of a ruby base,
        so we have to remember some state from expansion time to RenderRubyBase
        layout time.

        Nested template contents are not cloned by document.importNode
        https://bugs.webkit.org/show_bug.cgi?id=137619

        Reviewed by Andreas Kling.

        The bug was caused by Document.importNode not cloning HTMLTemplateElement's content.

        Fixed the bug by sharing code between Document::importNode and Node::cloneNode by
        generalizing Node::cloneNodeInternal, added in r177314, by taking the owner document
        as an argument. The most of code changes are the result of adding this argument.

        Document::importNode is the only function in which the actual logic changes.
        Note that the code to import TEXT_NODE, CDATA_SECTION_NODE, ENTITY_REFERENCE_NODE,
        PROCESSING_INSTRUCTION_NODE and COMMENT_NODE nodes are identical to that of cloneNode.

        This patch removes the call to hasValidNamespaceForElements in ELEMENT_NODE but this
        should not introduce an observable behavior change since all instantiated elements
        should have a valid namespace in the first place.

        Because DOCUMENT_NODE and DOCUMENT_TYPE_NODE cannot be imported and DOCUMENT_TYPE_NODE
        can only appear as a direct child of DOCUMENT_NODE, neither nodes nor unimplemented
        XPATH_NAMESPACE_NODE and XPATH_NAMESPACE_NODE can appear inside the recursive calls
        for ELEMENT_NODE and DOCUMENT_FRAGMENT_NODE nodes.

        While importNode behaves differently from cloneNode for ATTRIBUTE_NODE, namely that
        it merges all of its child nodes, this behavior isn't present when recursing inside
        ELEMENT_NODE and DOCUMENT_FRAGMENT_NODE since we are using cloneDataFromElement.

        Thus there should be no observable behavior changes for DOCUMENT_FRAGMENT_NODE and
        ELEMENT_NODE nodes either.

        After r163928, animated GIFs were not resumed when translated into view
        using '-webkit-transform' CSS property.

        This broke animated gifs on the mobile version of weibo.com (which is
        one of the most popular blogging sites in China) on iPhone. e.g.

        This patch calls FrameView::resumeVisibleImageAnimationsIncludingSubframes()
        after style recalc so that we resume animated images if they become visible
        after the style has changed. Doing so after layout wouldn't work because
        no layout happens in this case.

        REGRESSION (r168217): Images are cropped out during animation at jetblue.com
        https://bugs.webkit.org/show_bug.cgi?id=136410
        rdar://problem/18188533

        Reviewed by Dean Jackson.
        
        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.

        Change HysteresisActivity to use a lambda
        https://bugs.webkit.org/show_bug.cgi?id=139636

        Reviewed by Darin Adler.

        The current implementation provides notifications via callbacks to a delegate. Using a delegate
        with callbacks is limiting a number of ways. The callback names are very ambiguous, the callbacks
        must either be on a separate object (more boilerplate), or the callback must be public for
        HysteresisActivity to call them, or friends get involved. Without the boilerplate of extra
        delegate objects it's hard to scale use of these objects - a single object can't serve as a
        delegate for multiple HysteresisActivity members.

        Instead, make HysteresisActivity take a lambda to callback on state change. To simplify, changed
        HysteresisState to only track Started/Stopped states (removed WillStopPendingTimeout).

        In doing this change, it became apparent that there is nothing
        special about the shape-outside property that requires custom code, so
        it was changed to use a standard converter function.

        This allows the compiler to omit null checks at each call site, since we know

        REGRESSION(r160182): Fragment parser doesn't close a form element with a close tag
        https://bugs.webkit.org/show_bug.cgi?id=139561

        Reviewed by Darin Adler.

        The bug was caused by us not setting the form pointer in insertHTMLFormElement.
        Since we already avoid associating a form inside HTMLConstructionSite::createHTMLElement,
        we didn't need this code at all.

        Fixed the bug by partially reverting r160182.

        Test: fast/dom/dom-parse-close-form.html

        Reviewed by Simon Fraser.

        Final repaint rect at FrameView::scrollContentsFastPath needs to be pixel aligned (as opposed to snap to int).
        However we can't pixelsnap it until after ScrollView finished transitioning to Float/LayoutRect.
        Use enclosing int rect for now to ensure scrolling does not leave trails.

        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().
        
        No test because it's timing-dependent. Existing tests exercise the new assertion.

        [SVG Masking] Enable the use of <mask> elements for -webkit-mask-image
        https://bugs.webkit.org/show_bug.cgi?id=139294

        Reviewed by Simon Fraser.

        This patch links together all parts required for the functionality which improves 
        the -webkit-mask-image property by allowing it to reference a <mask> element defined 
        in an inline or external SVG document.
        Support for this new functionality has been added in a previous patch, under issue
        https://bugs.webkit.org/show_bug.cgi?id=139092. A more detailed description of how
        the new functionality works can be found in the ChangeLog for that commit.
        The containsSVGDocument in ScrollView has been removed because it was added in the
        previous patch but is no longer required.

        The "Show Debug Borders" toggle didn't cleanly remove layer borders from

        Fix by making updateDebugBorder() update the layer borders on the contents
        layer and cloned layers, moving some code around to avoid having colors
        in more than one place. If the borders are hidden, send an invalid color
        to PlatformCALayer::setBorderColor(), which now knows to remove the color

        Transform-style should not kill position:fixed
        https://bugs.webkit.org/show_bug.cgi?id=138122

        Reviewed by Dean Jackson.
        
        Various bits of rendering code checked RenderObject::hasTransform() for various
        reasons. Confusingly, this meant "has transform, or preserve-3d, or perspective".
        
        This patch teases those behaviors apart to produce the following behavior:
        
        1. "transform" acts as containing block for fixed position (no behavior change).
        2. "transform" acts as containing block for absolute/relative position (no behavior change).
        3. "perspective" does not act as containing block for fixed position (no behavior change).
        4. "perspective" acts as containing block for absolute/relative position (no behavior change).
        5. "preserve-3d" does not act as containing block for fixed position (behavior change).
        6. "preserve-3d" acts as containing block for absolute/relative position. This is not a
        behavior change, but seems like incorrect behavior (https://www.w3.org/Bugs/Public/show_bug.cgi?id=27566).
        However, we may be forced to keep it for compatibility.
        
        The gist of the change is to rename RenderObject::hasTransform() to RenderObject::hasTransformRelatedProperty(),
        and add hasTransform() with the more restrictive meaning. All call sites of hasTransform() were examined
        and fixed to produce the desired behaviors.

        Test: svg/animations/unsupported-animate-element-attributes.svg.
        
        The SVG base animator element should not animate an attribute if it is not
        supported by the target SVG element. Besides the CSS presentation attributes, 
        every SVG element defines which attributes can be animated by including them
        between BEGIN_DECLARE_ANIMATED_PROPERTIES and END_DECLARE_ANIMATED_PROPERTIES
        in the definition of the class. This definition builds attribute-properties map.
        When restarting the animation, the animator looks for all the attributes that
        match the animated attribute name. If the supported attribute-properties map
        does not include the animated attribute name, an empty element-properties list
        should be returned. When getting an empty element-properties list, the animator
        should not start any animation for the unsupported attribute.

        Do not start the animation if the animated attribute is not supported by 
        the target SVG element.

        Reviewed by Simon Fraser.

        This patch links together all parts required for the functionality which improves 
        the -webkit-mask-image property by allowing it to reference a <mask> element defined 
        in an inline or external SVG document.
        Support for this new functionality has been added in a previous patch, under issue
        https://bugs.webkit.org/show_bug.cgi?id=139092. A more detailed description of how
        the new functionality works can be found in the ChangeLog for that commit.
        The containsSVGDocument in ScrollView has been removed because it was added in the
        previous patch but is no longer required.

        After r163928, we would fail to animate a gif if:
        - it is used as a background image of a 0-height html element
        - it is used as a background image of a 0-height body element whose
          background is delegated to the root (because the root has no
          background).

        This is because in such cases, shouldRepaintForImageAnimation()
        should use the background rect instead of the renderer's overflow
        rect to determine if the image is inside the viewport. Both cases
        are addressed in this patch.

        This patch eliminates redundant repaint requests for inlines when neither the parent
        block flow nor any of the inline children are dirty.
        Previously,
        1. simple line layout always recalculated inline content positions regardless of whether
        the content needed relayout at all; as a result, it always triggered full repaint.
        2. inline tree layout ignored the needslayout flag on the last line and treated it dirty
        (unless it broke cleanly (<div>foo<br></div>)).
        This was an ancient workaround for an editing/insert use case, but it seems not to be the case anymore.

        Node::boundingBox() is completely broken for inline elements: it
        makes a rect from the top left of the first inline child to the
        bottom right of the last inline child, disregarding the intermediate
        inline children. This breaks with vertical text and with line
        breaks.

        What makes this problem worse is that some functions actually rely
        on this bad behavior. These functions are functions that use the
        Node's so-called "bounding box" to scroll to an anchor tag.

        This patch goes through all the call sites of Node::boundingBox(),
        and segregates them into calls that expect the true bounding box
        and calls that need this false bounding box. This patch then moves
        this false bounding box into RenderElement, using the name
        anchorRect(). Callers what want the correct bounding box have been
        updated to use RenderElement::absoluteBoundingBoxRect().

        <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.

        When a single simple selector was following a pseudo element, the relation evaluated

        Reviewed by Andreas Kling.

        There were two mistakes that were only caught in debug:

        The lexer was not calling isIdentifierStart() before parseIdentifier().
        Some identifier we were parsing should have been invalid.
        This was caught with an assertion in parseIdentifier().

        The other issue is that we were accumulating pointer to freed memory.
        The tokenizer for LANGRANGE was creating a new string with a StringBuilder.
        The problem is that CSSParserString does not keep the source string alive.
        Consequently, the list of language range was accumulating pointers to dead
        StringImpls.

        The fix there is to simply extend the token to take the original asterisk character

        Inline elements whose parents have small line-height are laid out too low
        https://bugs.webkit.org/show_bug.cgi?id=139375

        Reviewed by Dave Hyatt.

        This is a port of the Blink patch at
        https://src.chromium.org/viewvc/blink?revision=155253&view=revision.

        When laying out inline elements, we try to align leaf children's parents'
        baselines across the entire line. However, if you set line-height: 0px on a
        span, the entire InlineBox which represents that span will have a height of
        0, and therefore be laid out entirely on the baseline. In addition, we will
        try to vertically center the leaf text in the span's InlineBox, which means
        the leaf text will be vertically centered on the baseline. All the other
        major browsers do not have this behavior; instead, they line up the boxes
        as you would expect.

        This bug led to a rendering problem on the front page of the New York Times.

        Here is the ChangeLog from the Blink patch:

        Fix baseline position when it is outside the element's box

        Specifically, we shouldn't force the baseline to be inside the element. IE
        and FF don't do this, and it's incompatible with the CSS spec:
        
        "The baseline of an 'inline-block' is the baseline of its last line box in
        the normal flow, unless it has either no in-flow line boxes or if its
        'overflow' property has a computed value other than 'visible', in which case
        the baseline is the bottom margin edge."
        -- http://www.w3.org/TR/CSS21/visudet.html#leading
        
        It doesn't have a special case for "baseline is outside of the element's
        margin box".

        [CSS Grid Layout] Grid items must set a new formatting context.
        https://bugs.webkit.org/show_bug.cgi?id=139150

        Reviewed by David Hyatt.

        Grid item's margins must not collapse even when they may be adjoining to
        its content's margins. Also, setting a new formatting context prevents any
        'float' protruding content on the adjoining grid items.

        This patch also renames the expandsToEncloseOverhangingFloats to be more generic now,
        determining whether a new formatting context is set or not. This affects not only to
        how floats behave, but whether margins should collapse or not.

        Reviewed by Anders Carlsson.

        In [[getFooClass() alloc] init*], the type of the result of +alloc is id, so the compiler
        picks an arbitrary declaration of init*, not necessarily the Foo one. This can then lead
        to warnings or errors if the types or attributes don’t match, or to runtime errors if Foo
        doesn’t even have the expected initializer. The new allocFooInstance() returns a Foo *, thus
        avoiding the ambiguity.

        DisplayRefreshMonitorClient is the parent class of GraphicsLayerUpdater
        only if USE(REQUEST_ANIMATION_FRAME_DISPLAY_MONITOR) is true, so override
        is incorrect if USE(REQUEST_ANIMATION_FRAME_DISPLAY_MONITOR) is false.

        That's why r176915 broke the build on non PLATFORM(COCOA) platforms,

        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

        Fix style sharing with the "type" and "readonly" attributes
        https://bugs.webkit.org/show_bug.cgi?id=139283

        Reviewed by Antti Koivisto.

        There are two bugs adressed with this patch:
        1) The attributes "type" and "readonly" where only handled correctly
           for input elements. For everything else, they could incorrectly
           be ignored for style sharing.
        2) The handling of attributes was incorrect for selector lists, leading
           to various bugs (incorrect style sharing in some cases, disabling
           style sharing on valid cases).

        For [1], the problem was that attribute checking had been limited to
        StyleResolver::canShareStyleWithControl(). That function is for handling
        the special states of input element. For any other element, the attributes
        were simply ignored.

        For [2], there were a bunch of small problems. First, containsUncommonAttributeSelector()
        was not recursive, which caused it to ignored any nested selector list. This used to be
        correct but since we have advanced selectors we can no longer assumed selectors are not nested.

        A second issue was that any attribute in a selector list was causing us to fall back
        to the slow case. Now that we have the fast :matches(), we really don't want that.

        The function containsUncommonAttributeSelector() was transformed into a recursive function
        tracking where we are in the selector.

        At the entry point, we start with the flag "startsOnRightmostElement" set to true. The flag is then
        updated on the stack of each recursive call.

        For example, "webkit > is:matches(freaking > awesome)". We evalute "is" with the flag to true, then recurse
        into evaluating "freaking > awesome" with the flag still set to true. When we evalute ">", the flag
        is set to false to evaluate any following selectors.
        After evaluating "freaking > awesome", we go back to our previous stack frame, and the flag
        is back to true and we can continue evaluating with the curren top level state.

        From some logging, I discovered that the attribute handling is way too aggressive.
        This is not a regression and I cannot fix that easily so I left a fixme.

        [SVG Masking] Add support for referencing <mask> elements from -webkit-mask-image
        https://bugs.webkit.org/show_bug.cgi?id=139092

        Reviewed by Simon Fraser.

        This patch improves the -webkit-mask-image property by allowing it to reference
        a <mask> element defined in an inline or external SVG document.
        Up until now, each image to be used as a mask consisted of a FillLayer object 
        whose m_image member represented the mask. Now, in order to accomodate
        <mask> elements referenced by a fragment identifier (e.g. file.svg#mask1)
        a new class was created (MaskImageOperation) and added as a member of the 
        FillLayer. As such, from now on, all FillLayer objects used for masking will
        store the masking information in this new member.
        When parsing the -webkit-mask-image property (or the -webkit-mask shorthand)
        a new MaskImageOperation object is created for each image. If the value represents
        an external URL, a pending SVG document will be created which will be loaded 
        during the phase that loads the pending resources. When the download is complete,
        the MaskImageOperation is notified by the CachedSVGDocument class and checks if
        the received download is a valid SVG and the requested fragment identifier
        actually exists and identifies a <mask> element. If it does, that element's
        renderer (of type RenderSVGResourceMasker) will be used when painting the mask layers.
        Otherwise, the MaskImageOperation class will use the already downloaded data 
        buffer to create a CachedImage from it and use that instead, basically emulating
        the previous behavior, when only images were accepted. This ensures that all existing
        behavior, like painting entire SVGs, painting normal images (e.g. PNG/JPG), painting
        generated images (e.g. linear-gradient) works as it did before.

        No new tests required, this patch doesn't change any current functionality. 
        It only adds support for referencing <mask> elements for the -webkit-mask-image 
        property. This is sub-part 1 of the bigger patch https://bugs.webkit.org/show_bug.cgi?id=129682.

        AX: [ATK] Table captions and table rows are missing from the accessible hierarchy
        https://bugs.webkit.org/show_bug.cgi?id=139005

        Reviewed by Chris Fleizach.

        Expose table captions and rows via ATK. Accomplishing the former is done
        by role mapping and inclusion of the object as a child of the table for
        ATK. Accomplishing the latter was mostly a matter of deleting all the ATK
        platform code that had been forcing rows to be ignored. Because captions
        are not being exposed on the Mac, they are now explicitly being ignored
        for that platform.

        Generalize PageActivityAssertionToken
        https://bugs.webkit.org/show_bug.cgi?id=139106

        Reviewed by Sam Weinig.

        PageActivityAssertionToken is a RAII mechanism implementing a counter, used by PageThrottler
        to count user visible activity in progress on the page (currently page load and media playback).
        Use of an RAII type is prevents a number of possible errors, including double counting a single
        media element, or failing to decrement the count after a media element has been deallocated.

        The current implementation has a number of drawbacks that have been addressed by this refactoring:
         - specific to single use in PageThrottler class - not reusable.
         - incomplete encapsulation - the counter and WeakPtrFactory that comprise the current implementation
           are not encapsulated (are in the client type, PageThrottler).
         - tokens are not shared - PageActivityAssertionToken instances are managed by std::unique, every
           increment requires an object allocation.
         - redundancy - the current implementation uses a WeakPtr to safely reference the PageThrottler, this
           is internally implemented using a reference counted type, resulting in two counters being
           incremented (one in the PageActivityAssertionToken, one in the PageThrottler).

        In the reimplementation:
         - a callback is provided via a lambda function, which allows for easy reuse without a lot of
           boilerplate code.
         - the counter, callback and ownership of the otherwise weakly-owned token is encapsulated within the
           RefCounter type.
         - a single count within RefCounter::Count stores the counter value, and also manage the lifetime
           of this object.
         - standard RefPtrs are used to manage references to the RefCounter::Count.

        When matching :nth-child(An+B of selector list) or :nth-last-child(An+B of selector list),

        Ideally, out of flow positioned renderers do not have inline wrappers by the time we start
        placing inline boxes, but in certain case (optimized code path for descendantsHaveSameLineHeightAndBaseline()),
        they are still part of the inline box tree.

        Take into consideration canvas drawing for throttling DOM timers so
        that:
        - Timers drawing on a visible canvas can no longer get throttled.
          This fixes the following sites:
          - http://hint.fm/wind/
          - http://radar.weather.gov/Conus/full_loop.php
        - Timers that are drawing on a canvas that is not user observable
          now get throttled, thus using less CPU. As an example, on
          http://hint.fm/wind/, CPU usage is at 110% when the canvas is
          inside the viewport on my machine. CPU usage would remain at
          110% when scrolling the canvas outside the viewport before this
          patch. After this patch, the CPU usage goes down to 5% when
          the canvas is outside the viewport.

        E_Dbus is the simple wrapper of Dbus but it has not been maintained since EFL 1.8.
        Instead, EFL introduced Eldbus, which is almost similar with E_Dbus but provides more dbus like interface.
        This patch replaces E_Dbus implementation to Eldbus.

        https://bugs.webkit.org/show_bug.cgi?id=139017

        Reviewed by Mario Sanchez Prada.

        The options in a collapsed select element lack a node, so get the id
        attribute from the associated action element. In the case of a meter,
        the meter element itself is not exposed; its RenderMeter is instead.
        So associate the meter element's id with the exposed RenderMeter.

        No new tests. Instead, updated existing expectations to reflect the fix.

        Throttled DOMTimers can prevent their document from being garbage collected
        https://bugs.webkit.org/show_bug.cgi?id=138915

        Reviewed by Andreas Kling.

        Throttled DOMTimers whose interval depend on viewport changes would
        keep a Vector of elements outside viewport causing them to be throttled
        so that we could check later on (upon scroll or layout) if those
        elements are still outside viewport. The issue is that these elements
        could potentially be removed from the document (and destroyed) after
        the timer has fired. To handle this, DOMTimer was ref'ing the
        elements. Unfortunately, this was causing us to leak the document
        as the elements in the Vector would keep the document alive.

        To handle this issue, this patch updates the DOMTimer Vector to use
        weak pointers. The WeakPtrFactory is stored in ElementRareData to
        avoid wasting memory for all kinds of Elements (it is a fair assumption
        that the number of elements whose style is animated via timers is low).

        [iOS] Regression(r176202): line-height is wrong on marco.org
        https://bugs.webkit.org/show_bug.cgi?id=138970

        Reviewed by Simon Fraser.

        After r176202, on iOS with IOS_TEXT_AUTOSIZING enabled, we would
        multiply the lineHeight by RenderStyle::textSizeAdjust()::multiplier()
        unconditionally. However, we're only supposed to do so if
        RenderStyle::textSizeAdjust()::isPercentage() returns true. This
        patch reintroduces the textSizeAdjust().isPercentage() check that was
        inadvertently dropped when refactoring the code to be shared between
        iOS and OS X.

        Additionally, the multiplier is only supposed the be applied if the
        input CSSPrimitiveValue is a Length or a Number. However, after
        r176202, we would apply the multiplier if the CSSPrimitiveValue is
        a Percentage or a Number. This patch updates the code to match the
        behavior prior to r176202.

        Note that this function only calls ubrk_openRules() when the author has opted-in via
        using the -webkit-line-break CSS property. Eventually, we would like to be able to
        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
        therefore very slow. In fact, it's so slow that increasing our cache size in
        LineBreakIteratorPool doesn't actually help enough. Also note that the default value
        for the line-break CSS property is 'auto'.

        REGRESSION(r175259) Simple line layout text measuring behavior changed.
        https://bugs.webkit.org/show_bug.cgi?id=138947
        rdar://problem/19050653

        Reviewed by Antti Koivisto.

        In certain cases, when block flow needs to compute the preferred width of a particular text
        renderer, we use the non-simple line layout text measuring.
        However, the same text renderer might end up at simple line layout later.
        Complex line layout measures text including the trailing space and it subtracts
        (the constant value of) space width afterwards, while simple line layout measures
        runs without the extra space.
        In such cases, this may result different word widths and produce unexpected line breaking. (preferred width != final width)
        In long term, any text renderer qualified for simple line layout should go through the simple
        text measuring code path. (https://bugs.webkit.org/show_bug.cgi?id=138973)
        For now, just copy complex line layout behaviour. This also matches the previous simple line layout line breaking implementation.

        Reviewed by Sam Weinig.

        Update CSSPrimitiveValue::computeTime() to use primitiveType() instead
        of m_primitiveUnitType so that it properly handles calculated values.
        Without this, we would hit the ASSERT_NOT_REACHED() assertion in

        The CSS Parser was not handling calculated values when parsing the font
        weight. This would lead us to hit an assertion when parsing a font

        This patch updates parseFontWeight() to properly handle calculated

        [CSS Font Loading] Switch to dispatching events asynchronously
        https://bugs.webkit.org/show_bug.cgi?id=138755

        Reviewed by Simon Fraser.

        Moving FontLoader to dispatch events and notify callbacks similarly
        to EventSender or the GenericEventQueue. Several bugs have popped
        up in the past because FontLoader has been sending events during
        layout, and there is no need for that to be the case.

        Covered by existing font loader event tests. Added an additional
        test for the svg case, fontloader-svg-select.

        Reviewed by Benjamin Poulain.

        Upon destruction, a throttled DOMTimer whose interval depends on
        viewport changes will try to unregister itself from the view. It gets
        the view pointer from its Document. However, scriptExecutionContext()
        can return null if the Document is being destroyed (i.e. ~DOMTimer()
        is called from ~ScriptExecutionContext(), as the ScriptExecutionContext
        owns the DOMTimer).

        This patch adds a null check for scriptExecutionContext() in the

        Simple line layout: Introduce text fragment continuation.

        This patch extends simple line layout coverage to multiple text renderers.
        When a particular render flow has multiple text renderers (but not any other type)
        then we use simple line layout to process and paint the content. -other, existing requirements still apply
        so that for example if the content requires decoration, we bail out of simple line layout.

        [CSS Grid Layout] Replace the usage of size_t by unsigned
        https://bugs.webkit.org/show_bug.cgi?id=136218

        Reviewed by Benjamin Poulain.

        In general, size_t should be used for sizes of objects in
        memory. We're using it to represent indexes and spans in the
        grid. Now that the maximum number of tracks is 1 million, it
        should be safe to replace them by unsigned integers.

        No new tests as there is no change in functionality.

        Add the initial implementation of dynamic specificity for :matches()
        https://bugs.webkit.org/show_bug.cgi?id=138822

        Reviewed by Andreas Kling.

        Previously we completely ignored the selector list of :matches() when computing
        the specificity of the selector.

        The spec (http://dev.w3.org/csswg/selectors4/#specificity) says:
        "The specificity of a :matches() pseudo-class, however, is the specificity
         of the most specific complex selector that matched the given element."

        This patch does just that.

        In the CSS JIT, we only consider specificities that can be computed statically
        for now, this should be extended later.
        When the specificity is dynamic, we fall back to SelectorChecker. In that case,
        we execute every selector of the selector list and we keep the maximum value
        as the specificity for the whole :matches().

        This code is responsible for pushing block elements to the next column if
        the "orphans" CSS property is triggered. The mechanism by which this is
        achieved is to push the block down such that the origin of the block is
        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
        to entirely contain its text, so the top pieces were being drawn on the
        previous column.

        Reviewed by Antti Koivisto.

        DOMTimers sometimes didn't get unthrottled on scrolling. This is
        because we stopped listening for viewport changes every time the
        timer fires, but we didn't listen for those changes again if we
        decided the timer should stay throttled after the timer's action
        was executed.

        We should listen for viewport changes again after executing the
        timer's action, if there are elements outside the viewport causing
        the DOMTimer to be throttled, even if the throttleState hasn't

        AX: [ATK] Crash getting the orientation of a MenuListOption after the MenuList was removed from the document
        https://bugs.webkit.org/show_bug.cgi?id=138727

        Reviewed by Chris Fleizach.

        AccessibilityMenuListOption::elementRect() returns the value of the
        grandparent MenuList, asserting that the grandparent exists with that
        role. But it is possible to have an existing MenuListOption and remove
        the element which had been backing that MenuList from the document.
        Adding null checks prior to the assertions prevents our crashing if the
        parent or grandparent was removed.

        [CSS Grid Layout] Upgrade align-self and align-items parsing to CSS 3
        https://bugs.webkit.org/show_bug.cgi?id=133359

        Reviewed by David Hyatt.

        Broaden justify-self's parsing name as a preparation of migrating
        align-self, align-items and justify-items to the CSS 3 Alignment syntax.

        The current naming was too tied to justify-self and needs to
        be broadened. This will reduce the follow-up implementations'
        patches.

        Upgrade align-self and align-items parsing to CSS 3

        This change migrates the 2 properties to the CSS 3 Alignment
        parsing. The new parsing is identical to how we parse
        'justify-self'. The 2 properties need to be migrated together
        as they are used in tandem in CSSComputedStyleDeclaration.

        This change also removes EAlignItems as it is now unused.

        Throttle timers that change the style of elements outside the viewport
        https://bugs.webkit.org/show_bug.cgi?id=138292

        Reviewed by Antti Koivisto.

        Throttle timers that change the style of elements outside the viewport
        to 1 second, similarly to what was already done for timers interacting
        with non user observable plugins. To be conservative, we don't throttle
        timers that also cause DOM Tree modifications (e.g. adding/removing
        nodes, modify element attributes).

        On huffingtonpost.com, the CPU usage is at ~17% when the top scrolling
        banner is inside the viewport on my machine. Without this patch, CPU
        usage would stay ~17% when the banner is outside the viewport. Thanks
        to timer throttling, CPU usage now goes down to ~1.5%, without user
        observable side effects. The timers get unthrottled when they are
        inside the viewport again (i.e. due to scrolling or layout).

        On espn.com, the CPU usage goes down from ~7% at the top of the page
        to ~1% when scrolling to the bottom of the page. On ebay.com, CPU
        usage goes down from ~25% at the top of the page to less than 1% when
        scrolling to the bottom of the page.

        Implement :valid and :invalid matching for the fieldset element
        https://bugs.webkit.org/show_bug.cgi?id=138769

        Reviewed by Darin Adler.

        In the latest HTML spec, the pseudo classes :valid and :invalid match
        a fieldset element based on its descendants:
            https://html.spec.whatwg.org/#selector-valid
            https://html.spec.whatwg.org/#selector-invalid

        This patch adds that behavior.

        There are two key problems to solve with these pseudo classes on fieldset:
        -Efficient matching.
        -Style invalidation when any of the descendant changes.

        To implement the style invalidation, I have modified HTMLFormControlElement
        to notify its ancestor when its state changes.

        The first change is making the state fully internal to HTMLFormControlElement,
        we do not want subclass to be able to change the behavior and forget to update
        the ancestors.

        To achieve that encapsulation, the interface was changed a bit:
        -Neither willValidate() nor isValidFormControlElement() inherit from Element.
         Instead, willValidate() is the implementation of FormAssociatedElement's interface
         and it is final. The method isValidFormControlElement() becomes completely internal
         to HTMLFormControlElement.
        -Since willValidate() should no longer be re-implemented by subclass, the elements
         that were depending on it have been migrated to recalcWillValidate() to set
         the initial state as needed.

        With the validity state fully encapsulated in HTMLFormControlElement, all I need
        is a way to communicate that information to HTMLFieldSetElement ancestors.
        This is done in two cases:
        -The validity state changes.
        -The tree changes in a way that would make the input element not a descendant
         of a HTMLFieldSetElement.

        The invalidation is simply done by walking up the ancestors and adding the current
        element to a "validity dependency list" on each HTMLFieldSetElement.

        The reason is that HTMLFieldSetElement is a subclass of HTMLFormControlElement
        and it has its own definition of what Valid and Invalid mean when matching selectors.

        In HTMLFormControlElement, we must use the internal state,
        willValidate() and isValidFormControlElement() must be used directly.

        Crash when setting 'order' CSS property to a calculated value
        https://bugs.webkit.org/show_bug.cgi?id=138780

        Reviewed by Darin Adler.

        CSS Calculated values were not handled by the CSS parser for 'order'
        CSS property. As a result, using calculated values wouldn't work in
        release builds and would hit an assertion in debug builds.

        This patch updates the CSS parser to directly convert the
        CSS Calculated value into a simple integer CSSPrimitiveValue for
        'order' property. We could have marked CSS Calculated values as
        valid in the CSS Parser instead but this would have brought issues:
        - The calculated value needs to be adjusted to INT_MIN + 2 if it is less
          than that. This would force us to calculate the expression anyway.
        - The StyleBuilder would need updating to properly handle CSS Calculated
          values for 'order'.

        Assertion hit when setting a very large value to 'border-width' / 'font-size' CSS properties
        https://bugs.webkit.org/show_bug.cgi?id=138770

        Reviewed by Darin Adler.

        When setting a very large value to a CSS property, it is represented internally as
        infinity. r166114 already tried to deal with this by adding an std::isinf() check
        in CSSValuePool::createValue() and returning an identifier CSSPrimitiveValue with
        CSSValueInvalid value in such case. The issue is that doing leads to the
        StyleBuilder getting a CSSValueInvalid CSSPrimitive value as input, which is not
        handled and leads to assertions.

        This patch updates the CSSParser to detect cases where the double value is
        infinity earlier (in CSSParser::validUnit() and parseSimpleLengthValue()), so
        that we mark the value as invalid and actually drop it. As a result,
        CSSPrimitiveValues with CSSValueInvalid value no longer make their way to the
        StyleBuilder.

        Crash when setting 'alt' CSS property to inherit or initial
        https://bugs.webkit.org/show_bug.cgi?id=138774
        <rdar://problem/18995409>

        Reviewed by Chris Fleizach.

        The StyleResolver was not handling 'inherit' or 'initial' values for
        'alt' CSS property. As a result, the code was assuming the CSSValue
        was a CSSPrimitiveValue (although it could be a CSSInitialValue or
        a CSSInheritValue). In such case, the code would dereference a null
        pointer because primitiveValue is initialized using:
        CSSPrimitiveValue* primitiveValue = is<CSSPrimitiveValue>(*value)
            ? downcast<CSSPrimitiveValue>(value)
            : nullptr;

        Implement the matching for :nth-last-child(An+B of selector-list)
        https://bugs.webkit.org/show_bug.cgi?id=138650

        Reviewed by Andreas Kling.

        Matching is trivial based on the existing CSS4 infrastructure.

        The tricky part is style invalidation. In the cases of the old :nth-last-child()
        and :nth-last-of-type(), we were using the flag ChildrenAffectedByBackwardPositionalRules.

        The problem with ChildrenAffectedByBackwardPositionalRules is that it only invalidate
        subtrees when nodes are being added or removed. It is a valuable optimization by itself
        since tree updates are less common than property updates.

        For the case of property updates, I have added the new flag "ChildrenAffectedByPropertyBasedBackwardPositionalRules".
        It pretty much work the same way but invalidates subtree on style recalc.

        Unlike the other marking steps, ChildrenAffectedByPropertyBasedBackwardPositionalRules can only really

        trees with ChildrenAffectedByPropertyBasedBackwardPositionalRules by using a selector list that is a bit
        too generic. When that happen, we must be careful not invalidating everything, just the affected subtree.

        REGRESSION (r172826): Password field placeholder text is missing if
        placeholder attribute precedes type attribute

        <https://bugs.webkit.org/show_bug.cgi?id=138682>
        <rdar://problem/18574213> 

        When the placeholder attribute is encountered, a shadow tree is created
        to include the placeholder element. When the type attribute is
        encountered, the previous shadow tree is destroyed, and a new shadow
        tree is created. TextFieldInputType::createShadowSubtree() did not
        handle creating the placeholder element. 

        This regressed in r172826 because prior to r172826, the placeholder
        element would be recreated when
        HTMLTextFormControlElement::updatePlaceholderVisibility() was called.
        In r172826, updatePlaceholderVisibility() was changed to only show or

        https://bugs.webkit.org/show_bug.cgi?id=138524

        Reviewed by Ryosuke Niwa.

        When an HTMLInputElement was created by the parser, we would first call
        HTMLInputElement::create(), then call Element::parserSetAttributes() on
        the constructed input. With the previous implementation, this was a bit
        inefficient because HTMLInputElement::create() would construct a
        TextInputType inputType (as this is the default) as well as its
        corresponding shadow subtree. Then, parserSetAttributes() would often
        set the |type| attribute and would need to destroy this input type as
        well as its subtree if the new |type| is not 'text', to create a new
        inputType / shadow subtree of the right type. The profiler showed that
        this was fairly expensive.

        To improve this, this patch delays the inputType / shadow subtree
        creation when the HTMLInputElement is constructed by the parser, until
        the attributes are actually set by the parser. This way, we directly
        create an inputType / shadow subtree of the right type.

        I see a 1.4% speed up on speedometer (73.95 -> 75.0).

        Support unprefixed animation property names
        https://bugs.webkit.org/show_bug.cgi?id=138678
        <rdar://problem/18943059>

        Reviewed by Simon Fraser.

        Step 1 of 3 in unprefixing CSS animations: handling the
        property names and values.

        Unlike other unprefixing, where we use an alias that
        effectively removes the prefixed values from the code,
        for animations we need to keep the old values around so that
        existing content will not break (e.g. computed style).

        During testing I noticed that we didn't handle the
        (relatively) new animation-direction values of
        "reverse" and "alternate-reverse" when querying
        computed style.

        Reviewed by Darin Adler.

        Make several minor improvements to RenderListItem and clean up the
        code a bit.

        No new tests, no behavior change.

        * rendering/RenderListItem.cpp:
        (WebCore::isHTMLListElement):
        - Rename isList to isHTMLListElement() for clarity as it checks
          for HTMLOListElement and HTMLUListElement types
        - Inline the function as it is short.
        - Use is<HTML*Element>() for type checking
        - Update the argument to take a Node& instead of an Element*. This
          is because the argument is expected to the non-null. Also using
          looser typing here allows us to use this utility function is one
          more place, without impacting performance as
          hasTagName(HTMLQualifiedName) is defined on Node.

        (WebCore::enclosingList):
        - Pass the argument as a reference instead of a pointer as it is
          expected to be non-null.
        - Initialize firstNode before the loop to avoid the if (!firstNode)
          check for every iteration.

        (WebCore::nextListItem):
        - Take an Element as second argument instead of a RenderListItem*
          and provide convenience overloads so that we don't need to do
          null checks just because some calls sites call this function
          with 2 arguments and others with 1 argument. This way, we avoid
          unnecessary null checks as most call sites already do such
          checks (or have references).
        - Transform the while loop into a for loop for clarity.
        - Don't traverse an Element's subtree if the Element does not have
          a renderer as it is impossible of any of its descendant to have
          a renderer (and we are looking for a specific type of renderer).

        (WebCore::previousListItem):
        - Pass the item argument as a reference instead of a pointer as it
          is expected to be non-null.
        - Reduce the scope of the |current| so that it is now declared
          inside the loop.

        (WebCore::RenderListItem::updateItemValuesForOrderedList):
        (WebCore::RenderListItem::itemCountForOrderedList):
        - Pass argument as a reference instead of a pointer as it was expected
          to be non-null (There was an assertion in place to make sure of it).

        (WebCore::RenderListItem::calcValue):
        - Use is<HTMLOListElement>() instead of hasTagName().

        (WebCore::getParentOfFirstLineBox):
        - Rename variables to stop using abbreviations.
        - Pass arguments as references instead of pointers as they are expected
          to be non-null.
        - Remove the firstChild null check before the loop as it does not
          change behavior. The loop will abort early if firstChild is null
          and we will end up returning nullptr as well.
        - Use is<>() more for type checking.
        - Reuse the isHTMLListElement() utility function instead of duplicating
          its code inside this function.

        (WebCore::firstNonMarkerChild):
        - Pass argument as a reference as it is expected to be non-null.
        - Rename variable from result to child for clarity, as we are traversing
          the children.

        (WebCore::RenderListItem::markerTextWithSuffix):
        - Use String appending instead of StringBuilder as it simplifies the
          code a lot and should not impact performance in this case.

        (WebCore::RenderListItem::explicitValueChanged):
        - Restructure the code a bit to do the |listNode| null check before the
          loop, now that nextListItem() takes a reference in argument. This is
          the only call site where we didn't already know that listNode is
          non-null.

        (WebCore::previousOrNextItem):
        - Mark this function as inline as it is short and called repeatedly.

        Speed up HTMLTextFormControlElement::setInnerTextValue() a bit

        Reviewed by Darin Adler.

        Speed up HTMLTextFormControlElement::setInnerTextValue() a bit by:
        - Not doing a virtual isTextFormControl() call. Relying on innerTextElement()
          not returning null is sufficient.
        - Caching the result of innerTextElement() instead of repeatedly calling that
          virtual function.
        - De-virtualizing setFormControlValueMatchesRenderer() /
          formControlValueMatchesRenderer() as these are never overridden.
        - Moving the code constructing the innerTextValue from a
          TextControlInnerTextElement from innerTextValue() to a new
          innerTextValueFrom(TextControlInnerTextElement&) function and call this new
          function from setInnerTextValue() to avoid calling innerTextElement() again
          and making sure it is non-null
        - Do the tree traversal from innerTextElement's firstChild instead of from
          innerTextElement. The innerTextElement is a TextControlInnerTextElement.
          Therefore, it cannot be an HTMLBRElement or a Text node.

        No new tests, no behavior change.

        Reviewed by Alexey Proskuryakov.

        The above test fails if the HTMLMediaElement's "canplaythrough" event fires before the AudioTrackList's
        "addtrack" event fires. This can happen because each object keeps its own GenericEventQueue, which
        empties when that individual queue's timer fires. So events can be enqueued in the following order:
        1, A, 2, B, 3, C; but fired in a different order: 1, 2, 3, A, B, C.

        Make events enqueued in GenericEventQueues globally ordered, so that events are fired in the order
        which they are enqueued, regardless of which object owns the queue. Use a static queue of
        GenericEventQueues to manage which GenericEventQueue fires and in what order.

        GenericEventQueues will use a WeakPtrFactory to cancel pending events. Revoking a GenericEventQueue's
        weak pointers means those queue's entries will be skipped the next time the meta-queue is processed.

        This patch removes PassOwnPtr and OwnPtr in RenderThemeEfl::ThemePartCacheEntry::create().
        It would be good if we also remove create() factory function though, in this case, it is
        a little hard to remove it since the create() factory function does many works to create
        a ThemePartCacheEntry instance. Thus this patch just replaces PassOwnPtr|OwnPtr with
        std::unique_ptr<> and std::make_unique<> in RenderThemeEfl::ThemePartCacheEntry::create().

        Besides the theme entries have been maintained by Eina_List*. Unfortunately it doesn't support
        std::unique_ptr<> yet. Thus the Eina_List* should be replaced with Vector<std::unique_ptr<>>
        so that m_partCache has ownship of all EFL theme entries. This patch tries to keep original
        cache algorithm based on Vector class.

        This means that we can remove the old limitation for the number of
        repetitions in repeat(). Instead we now clamp the number of

        Lazily create HTMLInputElement's inputType and shadow subtree
        https://bugs.webkit.org/show_bug.cgi?id=138524

        Reviewed by Ryosuke Niwa.

        When an HTMLInputElement was created by the parser, we would first call
        HTMLInputElement::create(), then call Element::parserSetAttributes() on
        the constructed input. With the previous implementation, this was a bit
        inefficient because HTMLInputElement::create() would construct a
        TextInputType inputType (as this is the default) as well as its
        corresponding shadow subtree. Then, parserSetAttributes() would often
        set the |type| attribute and would need to destroy this input type as
        well as its subtree if the new |type| is not 'text', to create a new
        inputType / shadow subtree of the right type. The profiler showed that
        this was fairly expensive.

        To improve this, this patch delays the inputType / shadow subtree
        creation when the HTMLInputElement is constructed by the parser, until
        the attributes are actually set by the parser. This way, we directly
        create an inputType / shadow subtree of the right type.

        I see a 1.4% speed up on speedometer (73.95 -> 75.0).

        SVG foreign objects do not inherit the container coordinates system if they are repainted.
        https://bugs.webkit.org/show_bug.cgi?id=138481.

        Reviewed by Simon Fraser.

        If a foreign object is included in an SVG, it should inherit the coordinates system
        of the container if it is repainted. The foreign object is actually redrawn in the
        CSS coordinates system regardless of the transformation that may be applied to the
        container.

        The bug is RenderSVG* classes use computeFloatRectForRepaint(), but the rest of the
        render classes use computeRectForRepaint(). RenderSVGForeignObject::computeRectForRepaint()
        was not defined, so we end up hitting RenderObject::computeRectForRepaint() for 
        a RenderSVGTransformableContainer and completely miss the transform.

        Tests: svg/transforms/svg-transform-foreign-object-repaint.html

        Implement RenderSVGForeignObject::computeRectForRepaint() so we can apply the
        container transformation on the SVG foreign object repaint rectangle.

        Support throttling of DOMTimers using nested setTimeout() calls
        https://bugs.webkit.org/show_bug.cgi?id=138262

        Reviewed by Gavin Barraclough.

        Extend DOMTimers throttling support to timers that are using nested
        setTimeout() calls instead of a setInterval(). To achieve this, this
        patch introduces a NestedTimersMap singleton class where nested timers
        are added, and for which we potentially update the next firing time,
        after the parent timer is done executing.

        I have verified this helps on ebay.com for example, which has timers
        interacting with non-visible plugins that are scheduled using nested
        setTimeout() calls with a frequency of 150 / 200 ms.

        This is a second take on r175441, which caused intermittent crashes.
        This time, nested timers are removed from the NestedTimersMap when
        DOMTimer::removeById() is called. It would be unsafe to use the nested
        timer afterwards because we don't hold a strong reference to it and
        the ScriptExecutionContext is unref'ing the DOMTimer when
        ScriptExecutionContext::removeTimeout() is called from
        DOMTimer::removeById().

        [iOS WK2] Layers with negative z position disapear behind the page tiles

        Some crufty iOS-only code in RenderLayerBacking::parentForSublayers() caused us to fail
        to use the m_childContainmentLayer as the ancestor for descendants, so layers with
        negative z position would get depth-sorted behind the tiles.
        
        Fix by removing that code.

        [OSX] Some words are placed on top of each other in complex text layout
        https://bugs.webkit.org/show_bug.cgi?id=138348

        Reviewed by Simon Fraser.

        Some complex text layouts have lots of diacritics being placed all over the place.
        CoreText sometimes compensates for this by adjusting the advances of the glyphs
        throughout the string to make glyphs appear in the correct place. This means that
        we can't naively cache the width of a space character; instead, we must obey
        CoreText when it gives us an advance for a space.

        Make the Selector's specificity part of Selector matching
        https://bugs.webkit.org/show_bug.cgi?id=138486

        Reviewed by Andreas Kling.

        In CSS Selectors Level 4, the specificity of selectors is computed dynamically
        based on which element is being matched.

        For example, a selector:
            :matches(#foo, .bar, baz)
        has a specificity of
            (1, 0, 0) on <baz id=foo class=bar>
            (0, 1, 0) on <baz class=bar>
            (0, 0, 1) on <baz>

        Previously, the specificity of each selector was computed statically when populating
        RuleSet. With more recent CSS, this gives us the wrong specificity because we do not know
        how the selectors applies to the target.

        This patch moves one tiny step in the direction of dynamic specificity. The specificity
        is removed from RuleSet and is moved inside Selector Matching.

        There is one bit worth keeping static: matching based on rule hash. This path is important
        to avoid spending time compiling trivial selectors.
        In order to keep rule hash matching working, the RuleData store which specificity class
        the rule has in addition to the information about matching/not-matching. When going through
        the fast path in ElementCollector, we compute the right specificity based on the type
        of rule-hash matching.

        Reviewed by Ryosuke Niwa.

        Stop special-casing wbr elements in HTMLElement::createElementRenderer()
        and move the code to a HTMLWBRElement subclass instead, that is
        overriding createElementRenderer(). This function is already virtual.

        No new tests, no behavior change.

        De-templatize Timer
        https://bugs.webkit.org/show_bug.cgi?id=138450

        Reviewed by Anders Carlsson.

        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).

        Give pseudo elements the correct specificity
        https://bugs.webkit.org/show_bug.cgi?id=138378

        WebKit had an old silly bug where pseudo elements were given specificity in the class B

        The media controls were relying on the bug to override the style of input[type=range].

        Ideally we should either:
        -Implement some kind of high level style isolation (e.g. CSS Scoping).
        -Fix the media control tree to use regular CSS scoped by a shadow pseudo ID.

        Until we have one of those, I just fixed the styling by forcing the properties with lower
        specificity with !important.

        Avoid backing store for opacity:0 descendant layers

        Reviewed by Dean Jackson.
        
        If a composited layer has no rendered content but a painting zero-opacity descendant
        layer, than we can avoid making backing store.
        
        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).

        Assertion hit DOMTimer::updateTimerIntervalIfNecessary()
        https://bugs.webkit.org/show_bug.cgi?id=138440

        Reviewed by Geoffrey Garen.

        We sometimes hit the ASSERT(repeatInterval() == previousInterval)
        assertion in DOMTimer::updateTimerIntervalIfNecessary() when visiting
        the following pages:

        http://longform.org/posts/like-something-the-lord-made

        After debugging, the issue turned out to be that we are comparing
        floating point numbers using ==, and the check sometimes fails even
        though the values really close to each other. This patch updates the
        DOMTimer code to use WTF::withinEpsilon() instead of operator==()
        to compare the floating point intervals.

        I confirmed manually that the assertion is no longer hit.

        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.

        Stop special-casing the empty string in HTMLInputElement.type setter.
        Previously, if input.type is set to "", we would remove the type
        attribute. This is inconsistent with the specification and the behavior
        of other browsers (tested Firefox 33 and Chrome 38). Instead, we should
        set the attribute to the empty string.

        Also stop treating null as a null string to align with the
        specification and other browsers (tested Firefox 33 and Chrome 38).

        Finally, update HTMLInputElement::setType() to take an AtomicString in
        argument instead of a String as it ends up calling setAttribute(), and
        thus needing an AtomicString.

        https://bugs.webkit.org/show_bug.cgi?id=138346

        Reviewed by Antti Koivisto.

        Add a class that can act as the primary iterator/fragment handling interface to the line parser.
        This helps adding support multiple renderer elements without changing the parser logic.
        Currently it operates strictly on the first child of the RenderBlockFlow.  

        Covered by existing tests.

        When a fullscreen video gets dismissed programmatically, for instance for removing
        a webview from the view hierarchy, it can put the device in an incorrect orientation.
        Make sure we retain the window of parentView when we attempt to go to fullscreen and use
        the retained window for putting the device in correct orientation after dismissal.

        Reviewed by Andreas Kling.

        The code handling overflow in CSSSelector::specificity() was assuming that the value
        returned by specificityForOneSelector() can only overflow one field at a time.

        That assumption is no longer correct with the extended :not(). It is now possible to have
        a complex selector saturating multiple fields inside a single :not().

        This patch solves the problem by considering each field independently.

        Reviewed by Dirk Schulze.

        Fixed implementation of SVG animated angles and the SVG

        SVG animated angle was missing the logic to support animation
        from auto to a numeric angle value - this is now added.
        The SVG marker element getter for orientType was not returning

        the initial value and the animated values were of different types)

        Reviewed by Antti Koivisto.

        A RenderListMarker is either in-tree and owned by the tree, or out-of-tree
        and owned by a RenderListItem.

        This patch changes RenderListItem::m_marker to be a raw pointer, and removes
        the special handling of list markers in RenderElement child teardown.

        We also remove the willBeDestroyed() hook. It was used to clear out the
        m_marker pointer, but this is now done in the regular ~RenderListItem()
        destructor with an assertion for marker sanity. m_marker is automatically
        nulled out by a didDestroyListMarker() callback on RenderListItem.

        Extend DOMTimers throttling support to timers that are using nested
        setTimeout() calls instead of a setInterval(). To achieve this, this
        patch introduces a NestedTimersVector singleton class where nested
        timers are appended, and for which we potentially update the next
        firing time, after the parent timer is done executing.

        I have verified this helps on cnn.com for example, which has timers
        interacting with non-visible plugins that are scheduled using nested
        setTimeout() calls with a frequency of 150 / 200 ms.

        Pseudo classes with an escaped parenthesis generate invalid rules
        https://bugs.webkit.org/show_bug.cgi?id=138266

        Reviewed by Antti Koivisto.

        Since the functional pseudo classes are part of the list of PseudoClassAndCompatibilityElement,
        they could be created by the rule
             pseudo:
                 ':' IDENT
        if the parenthesis is escaped. For example, with ":not\\(", the IDENT would be
        "not(", CSSParserSelector::parsePseudoClassAndCompatibilityElementSelector would
        find a pseudo class type of PseudoClassNot, and the action would create an invalid
        CSSSelector for a :not() without nested selector.

        This patch fixes the issue by detecting the function case in
        CSSParserSelector::parsePseudoClassAndCompatibilityElementSelector().

        An other solution would be to split PseudoClassAndCompatibilityElement into simple pseudo class
        and functional pseudo classes. We may do that some day but at the moment it is a lot of work with
        a little benefit.

        Make CSSDefaultStyleSheets::ensureDefaultStyleSheetsForElement() faster
        https://bugs.webkit.org/show_bug.cgi?id=138227

        Reviewed by Benjamin Poulain.

        Restructure CSSDefaultStyleSheets::ensureDefaultStyleSheetsForElement()
        a bit to do less if checks. The previous implementation was doing 7 if
        checks no matter the input value. The new implementation does less
        if checks depending on the input type.

        Also, the isImageControlsRootElement() was showing in the profiles so
        I updated the condition to only do this virtual function call if the
        input is an HTMLDivElement (which we can check more efficiently).

        With the change, I see that we're spending about ~26% less time in
        this method when running speedometer. However, the impact on the
        overall score is within noise.

        Reviewed by Benjamin Poulain.

        Optimize HTMLVideoElement / HTMLAudioElement type checks a bit by:
        1. Using is<HTMLMediaElement>() instead of
           (is<HTMLVideoElement>() || is<HTMLAudioElement>()) if the caller is
           interested in both video and audio elements. This is faster because
           it ends up doing:
               - virtual call to Element::isMediaElement()
           instead of
               - Node::isHTMLElement() +
                 virtual call to HTMLElement::isHTMLUnknownElement() +
                 2 * HTMLElement::hasTagName()
        2. Updating HTMLVideoElement / HTMLAudioElement type traits
           specializations to:
           - Avoid doing any virtual function call if the input type is an
             HTMLMediaElement (which is common in the code base).
           - Speed up check if the input is an Element by doing:
               - virtual call to Element::isMediaElement() +
                 HTMLElement::hasTagName()
             instead of
               - Node::isHTMLElement() +
                 virtual call to !HTMLElement::isHTMLUnknownElement() +
                 HTMLElement::hasTagName()
             The speed stays the same if the input is a Node or an HTMLElement.

        To indicate that they would like to recevie expired session confirmation messages, clients
        will create a MediaKeySession with a type parameter of "keyrelease". The code which validates
        this type needs to be updated to recognize "keyrelease" as a valid type.

        Also, the code which validates update() requests needs to allow updates containing the string
        "acknowledged", so that clients can request the confirmation messages be discarded.

        Reviewed by Andreas Kling.

        We're hitting the ASSERTION because if the number of tracks an
        item spans does greatly exceed the available logical space, then
        the result of the division availableLogicalSpace/numberOfTracks is
        truncated to 0. So the ASSERTION was theoretically right because
        the result has to be always >0 (as the dividend > 0) but the fact
        that the result is a LayoutUnit forces us to accept 0 as a valid
        outcome of the operation.

        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).

        Speed up line parsing for simple line layout.

        Reviewed by Antti Koivisto.
        
        This patch speeds up the line parsing for simple line layout by
        reducing the number of text measurement calls.
        The parsing logic hasn't changed. We simply walk over
        the whitespace/non-whitespace fragments and measure them to
        figure out whether they fit.
        The performance gain mainly comes from the more efficient line wrapping
        so that we don't re-measure the fragment when it is pushed to
        the next line.

        No change in behaviour. (except the empty line-break run removal.)

        https://bugs.webkit.org/show_bug.cgi?id=137754

        Reviewed by Brent Fulgham.

        It turns out that, if you pass nil to -[AVPlayerItemVideoOutput initWithPixelBufferAttributes:]
        the video output will not attempt to conform the resulting pixel buffers into a particular format.
        This means that adding such a video output to a AVPlayerItem should have almost no performance
        penalty, since the video output does not even copy the resulting buffers, but rather just retains
        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.

        Use separate HashMaps for common and uncommon headers in HTTPHeaderMap
        https://bugs.webkit.org/show_bug.cgi?id=138079

        Reviewed by Anders Carlsson.

        Use separate HashMaps for common and uncommon headers in HTTPHeaderMap:
        - a (faster) HashMap<HTTPHeaderMap, String> for common HTTP headers
        - a HashMap<String, String, CaseFoldingHash> for uncommon ones

        This avoids having to construct Strings from HTTPHeaderMap values for
        storing. This also means we have less isolated String copies to do when
        creating cross-thread data. The common headers HashMap should also be
        a bit more efficient due to faster hashing and faster key comparison in
        case of collision.

        Some calls sites can also benefit from having direct access to common
        headers of the request in HTTPHeaderName type.

        This patch adds a new HTTPHeaderMapConstIterator iterator type for
        HTTPHeaderMap so that call sites that do not need / want to distinguish
        common / uncommon headers still do not need to. They can keep using
        modern C++ loops over HTTPHeaderMap objects and get <String, String>
        key/value pairs.

        No new tests, no behavior change.

        (WebCore::shouldIgnoreHeaderForCacheReuse):
        Update argument type to be a HTTPHeaderName instead of a String as

        call findHTTPHeaderName(). This is no longer needed now that the
        call site now has direct access to common headers in HTTPHeaderName
        type.

        (WebCore::CachedRawResource::canReuse):
        - Only call shouldIgnoreHeaderForCacheReuse() for common HTTP headers.
        - Slightly optimize the second loop (the one over oldHeaderMap) to only
          check that the key is present in newHeaderMap, without actually
          comparing the String values. If the String values were different, the
          first loop would have seen it already and we would have returned
          early.

        Images with usemap should not have a link state

        Reviewed by Andreas Kling.

        Image tags were incorrectly getting a link state if a usemap is defined.
        The <area> of the usemap is supposed to get the link state, but never the image.

        Unfortunately, the Accessibility code was relying on the wrong behavior
        to set the ImageMapRole, most of the patch is updating that code to get
        the correct role without the link state.

        Web Inspector: timelines should not count time elapsed while paused in the debugger
        https://bugs.webkit.org/show_bug.cgi?id=136351

        Reviewed by Timothy Hatcher.

        To avoid counting time elapsed while the debugger is paused, timeline records should
        keep track of time elapsed since the start of timeline capturing, rather than wall clock
        timestamps. We can easily compute elapsed time by sharing a Stopwatch instance through the
        inspector environment. The stopwatch runs with timelines and is paused with the debugger,
        so subsequent time measurements will not include time elapsed while the debugger is paused.

        This refactoring is safe because start and end times are only used to graph records; the
        timestamp's actual value is irrelevant and is not displayed in the user interface. Date
        timestamps are still included with network-related records as part of their header data.

        No new tests, because we cannot reliably test timing changes induced by debugger pauses.
        It is possible for records to accrue time before the debugger pauses or after it resumes.

        Avoid unnecessary NSURLRequest copies in ResourceRequest::doUpdatePlatformRequest() / doUpdatePlatformHTTPBody()

        Reviewed by Alexey Proskuryakov.

        Avoid unnecessary NSURLRequest copies in ResourceRequest::doUpdatePlatformRequest()
        / doUpdatePlatformHTTPBody(). It turns out that about half the time, the
        m_nsRequest member is already mutable so it is unnecessary to call
        [NSURLRequest mutableCopy], we can just cast it to an NSMutableURLRequest* and
        avoid copying.

        This patch also moves the code to a new ensureMutableNSURLRequest() method to
        avoid duplicating the logic.

        I see that we spend ~21% less time in these 2 functions when loading

        BackingStoreBackendCairo is the base class that contains common
        members like the surface and size. BackingStoreBackendCairoImpl is
        the implementation using only cairo, and BackingStoreBackendCairoX11

        information it needs as constructor parameters, instead of using a
        GtkWidget and GTK+ X11 API. BackingStoreBackendCairoImpl receives

        [iOS] Toggling overflow:scroll to hidden on element with -webkit-overflow-scrolling:touch can cause children to disappear

        When toggling overflow from scroll to hidden on an element with -webkit-overflow-scrolling:touch,
        we'd fail to do a compositing layer rebuild, which caused various issues like unparented
        descendants, and misplaced and unrepainted content.
        
        This happened because we'd get to RenderLayerBacking::updateConfiguration() via styleChanged
        with the view needing layout, so never hit the updateScrollingLayers() code, and the subsequent
        updateCompositingLayers() would be a no-op.
        
        Fix by explicitly triggering a layer rebuild when style changes such that the touch-scrollability
        of an element changes, as we do for changes in clip.

        This patch is renaming isAccessibilityTable() to
        isExposableThroughAccessibility(), makes it non-virtual and defines it
        on AccessibilityTable only, for clarity.

        This patch also renames isTableExposableThroughAccessibility() to

        Reviewed by Andreas Kling.

        Reduce the amount of is<MutableStyleProperties>() checks in

        - Removing the checks in each method of StyleProperties::PropertyReference,

        - Providing faster propertyCount() / propertyAt() / isEmpty() methods on
          MutableStyleProperties / ImmutableStyleProperties as a lot of callers use
          tight typing.
        - Using tighter typing at call sites whenever possible.

        Ideally, we could be able to use iterators instead of propertyCount() /
        propertyAt() but this is not trivial to do efficiently as the
        representation in memory is fundamentally different for MutableStyleProperties

        [Mac][WK2] Fix applicationIsSafari() detection
        https://bugs.webkit.org/show_bug.cgi?id=137893

        Reviewed by Alexey Proskuryakov.

        I noticed when profiling Safari on Mac that we were exercising a code
        path we shouldn't because it is meant for other applications that
        Safari.

        The detection relies on the applicationIsSafari() function in
        RuntimeApplicationChecks.cpp. This was in some cases returning false on
        my machine even though I was running Safari so I investigated a bit and
        noticed that the check relies on the main bundle identifier string and
        is doing:
        isSafari = mainBundleIsEqualTo("com.apple.Safari")
            || mainBundleIsEqualTo("com.apple.WebProcess");

        This WebProcess detection is very unreliable because:
        - It matches other apps than Safari's WebProcesses
        - The bundle name for the WebProcess is sometimes
        "com.apple.WebKit.WebContent" or
        "com.apple.WebKit.WebContent.Development".

        The solution used in this patch is to move the applicationIsSafari()
        check to the UIProcess so that the check actually succeeds reliably.
        The call site for applicationIsSafari() was in
        ResourceRequest::useQuickLookResourceCachingQuirks(). This match
        removes that logic from ResourceRequest and move it to
        FrameLoaderClient as only the FrameLoader is interested in this
        information. The logic to determine if we should use QuickLook
        resource caching quirks is moved to a new QuickLook class under
        platform/ as the code needs to be shared between WebKit and WebKit2.
        On WebKit2, we make use that code on the UIProcess side and pass
        the flag as a parameter when constructing the WebProcess. The flag
        is then stored on the WebProcess and queried by WebFrameLoaderClient.

        Previously, we would spend ~1% of the WebProcess cpu time (when loading
        apple.com) trying to detect if we should use QuickLook resource caching
        quirks even though that check was supposed to be disabled and return
        early when running Safari.

        No new tests, not easily testable.

        Add initial support for generating the StyleBuilder from CSSPropertyNames.in
        https://bugs.webkit.org/show_bug.cgi?id=137910

        Reviewed by Andreas Kling.

        Add initial support for generating the StyleBuilder from
        CSSPropertyNames.in. This is a first step towards getting rid of the
        legacy DeprecatedStyleBuilder class and having everything defined in one
        place (CSSPropertyNames.in).

        This patch updates makeprop.pl script to generate a StyleBuilder.cpp
        file that generate a the StyleBuilder::applyProperty() method
        implementation using a huge switch statement for all the CSS
        properties. With this patch, we are now generating the new StyleBuilder
        code for all the "simple" CSS properties (i.e. those that were using
        ApplyPropertyDefault<> in DeprecatedStyleBuilder.cpp). I am using a
        "NewStyleBuilder" option in CSSPropertyNames.in for properties that
        we generate to help with improving incrementally the generator. Once
        we are able to generate all properties, this transition option will
        do away and become the default.

        By default, the generator will make an educated guess for the type
        name, the getter, the setter and the initial function of each property.
        For example, for the border-collapse property, it will use:
        - TypeName: EBorderCollapse (i.e. 'E' + PropertyId)
        - Getter: borderCollapse() (i.e. PropertyId with first letter lowercased)
        - Setter: setBorderCollapse() (i.e. 'set' + PropertyId)
        - Initial: initialBorderCollapse() (i.e. 'initial' + PropertyId)

        This works for most properties. For properties that need
        special-casing, developers can use the following options in
        CSSPropertyNames.in:
        - TypeName: Overrides the type name
        - Getter: Overrides the getter name
        - Setter: Overrides the setter name
        - Initial: Overrides the initial function name
        - NameForMethods: Overrides the Getter / Setter / Initial function
          names. For e.g. "NameForMethods=OverflowWrap" will use
          "overflowWrap() / setOverflowWrap() / initialOverflowWrap()".

        The patch is inspired by the following Blink revision by
        <timloh@chromium.org>:

        Match spec for font-weight: bolder|lighter
        https://bugs.webkit.org/show_bug.cgi?id=137919

        Reviewed by Andreas Kling.

        This patch is a merge of Blink's
        https://chromiumcodereview.appspot.com/15994009
        
        Currently, bolder and lighter change font-weight in a non-compliant way.
        The spec (http://www.w3.org/TR/css3-fonts/#bolderlighter) defines
        exactly what the computed values should be given the inherited weight values,
        so we should match those.
        
        The removed FIXME's for selecting the next lightest/heaviest weight from
        the used font family seems to refer to behaviour from
        CSS1 (http://www.w3.org/TR/CSS1/#font-weight), while this is replaced
        with a simpler procedure for resolving bolder and lighter in font weights
        in CSS2 (http://www.w3.org/TR/CSS2/fonts.html#propdef-font-weight) and CSS3 (link above).
        
        and https://codereview.chromium.org/137813004
        
        According to http://dev.w3.org/csswg/css-fonts/#font-weight-prop, the computed
        weight of 'lighter' and 'bolder' are based on the inherited 'font-weight', so set
        that inherited weight before calculating 'lighter' and 'bolder'.

        As a result, style was not invalidated properly when any property listed in

        [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.

        ResourceRequest deserialization unnecessarily calls partitionName() on encoded cache partition
        https://bugs.webkit.org/show_bug.cgi?id=137797

        Reviewed by Darin Adler.

        ResourceRequest deserialization was unnecessarily calling partitionName()
        on the decoded cache partition. In the deserialization case, we already
        know the cache partition is a valid partition name so we can bypass the
        call to partitionName() (which is fairly expensive) for performance.

        This patch adds a setDomainForCachePartion() method to ResourceRequest
        that calls partitionName() on the domain argument, and moves all the
        callers of setCachedPartition() to this new setter, except
        ArgumentCoder<ResourceRequest>::decode().

        This patch updates the setCachedPartition() to merely set the
        m_cachePartition member, without calling partitionName() on the
        argument. There is also a new assertion in place to make sure the
        argument is a valid partition name.

        No new tests, no behavior change.

        Add a new media query from CSS Level 4, "inverted-colors", and
        implement the Apple backends for the "monochrome" media query.

        The platform code went into PlatformScreenMac, which already
        had a screenIsMonochrome method. This now calls into Core
        Graphics via SPI. I added a screenHasInvertedColors
        method which tests for inversion. On iOS, there is public API
        for both queries. On Windows, we try to use CoreGraphics.

        At the moment neither of these media queries re-evaluate
        automatically if the user changes their mode. The page will
        need to be reloaded. It is possible to detect a change on iOS,
        but not OS X.

        I decided to not add an ENABLE flag for this, mostly because it
        is such an isolated feature and seems very unlikely to be
        controversial. I don't expect the syntax to change. (I'm sure
        this comment will come back to haunt me.)

        Testing this automatically is slightly tricky. We'd need

        [Mac] Optimize cookiesForDOM() by filtering and serializing cookies in a single pass
        https://bugs.webkit.org/show_bug.cgi?id=137869

        Reviewed by Darin Adler.

        Optimize cookiesForDOM() by filtering and serializing in 1 pass instead of 2.

        Previously, when accessing document.cookie, we ended up doing the following:
        1. Call wkHTTPCookiesForURL() to get an NSArray of NSHTTPCookies.
        2. Call filterCookies() to filter out cookies that are httpOnly or with an
           empty name, thus allocating a new NSMutableArray.
        3. Call NSHTTPCookie's requestHeaderFieldsWithCookies() to serialize the
           cookies
        4. Construct a WTF::String from the NSString*

        There were several inefficiencies here:
        1. We needed to pre-filter the cookies and allocate a new NSMutableArray
           before calling requestHeaderFieldsWithCookies()
        2. requestHeaderFieldsWithCookies() does more things that we actually need.
           It constructs a Dictionary of header fields, of which we query the
           "Cookie" field, even though we merely want a ';'-separated string
           representation of the cookies in "key=value" form.

        With this patch, we now take care of the string serialization ourselves,
        using a StringBuilder as it is trivial to do. This also allows us to filter
        out the httpOnly/invalid cookies as we do the serialization instead of
        having a first pass to do so.

        When scrolling the http://www.apple.com/iphone/ entire page down, then up,
        se were spending ~13.1% of the NetworkProcess time in cookiesForDOM()
        (~96ms) on my machine. With the patch, we spend ~23% less time in
        cookiesForDOM() (~74ms).

        No new tests, no behavior change.

        Make a better use of the available registers when compiling nested selector lists
        https://bugs.webkit.org/show_bug.cgi?id=137802

        Reviewed by Andreas Kling.

        Previously, when compiling a nested selector list, the compiler would start by pushing all
        the allocated registers to the stack to free them for the compiled selector list.
        While neat to ensure register allocation is correct, this is very inefficient.

        This patch brings the first step for reducing the overhead. Instead of pushing everything
        to the stack, we just push as many registers as we need for compiling the selector list.

        In most cases, we have so many registers that we don't even need to push anything to the stack.

        Test: fast/selectors/nth-child-of-register-requirement.html

        * cssjit/SelectorCompiler.cpp:
        Add an explicit type for SelectorList to keep information aggregated from all
        SelectorFragmentList inside it.

        SelectorFragmentList is also extended to include its register and stack requirements.
        This information is then used to create a SelectorList and to compile the SelectorFragmentList.

        (WebCore::SelectorCompiler::hasAnyCombinators):
        We only change the elementAddressRegister when moving over combinators. This is used to detect
        if a selector list clobber the elementAddressRegister or leave it untouched.

        (WebCore::SelectorCompiler::computeBacktrackingMemoryRequirements):
        (WebCore::SelectorCompiler::computeBacktrackingInformation):
        Instead of returning a BacktrackingMemoryRequirements, update the SelectorFragmentList and SelectorList directly.

        (WebCore::SelectorCompiler::SelectorCodeGenerator::generateElementMatchesSelectorList):
        This is where the fun happen.
        First step is keep the input untouched. For now it is simply pushed on the stack. This can be improved later.

        Then we find how many allocated registers we need to save to compile the input selector list. We push those registers
        to the stack and give them back to the register allocator.

        With enough registers we can now compile the nested selector list. The code has changed a bit for efficiency. Instead
        of creating a shortcut for success case, the code now exit on error and proceed on success. This is the general pattern
        of SelectorCompiler and it is quite a bit more efficient in the common cases.

        Finally, we reallocate the registers and get their values back from the stack. The "tail" is duplicated but that's fine
        because in the vast majority of cases it is 1 or 2 pop.

        Test: http/tests/media/hls/hls-audio-tracks.html

        Support selecting audio "tracks" in HLS streams by exposing AVMediaSelectionOptions
        as entries in the video's AudioTrackList.

        AVMediaSessionGroups and AVPlayerItems don't have KVO or notifications to track when options
        are selected and deselected, so wrap AVMediaSessionGroup and AVMediaSessionOption in C++
        wrappers. Each AVMediaSelectionGroup can have only one AVMediaSelectionOption selected at a
        time, so the wrapper will take care of answering which AVMediaSelectionOption is currently
        selected, as without KVO notifications, asking the AVMediaSelectionGroup directly is
        inconsistent. Because setting the selected option multiple times in the same run-loop can
        cause flakiness, coalesce calls to setSelectedOption() by setting a one-shot timer to do
        the actual selection in the next run-loop.

        ASSERTION  FAILED in WebCore::RenderFlowThread::getRegionRangeForBox
        https://bugs.webkit.org/show_bug.cgi?id=135563

        Reviewed by David Hyatt.

        The new multi-column code doesn't work correctly when the document contains nested fragmentation
        contexts. The problem is the current flow thread concept that can store only one RenderFlowThread
        at a time and use it during layout.

        The stored flow thread is always correct for regions because named flow threads are absolutley positioned
        so every child renderer is contained inside them (with the expcetion of fixed positioned elements which are
        treated separately).

        For multi-column elements this is no longer the case. An absolutely positioned element inside a static
        multi-column element will be contained by a block outside the fragmentation context. It can even be
        contained by a different multi-column element in the case of nested flow threads.

        The patch below explores a solution that's not based on a current flow thread stored globally. The proposed
        patch makes every block to store a pointer to its fragmentation context and a flag that states if this pointer
        needs to be updated or not. If the renderer is not a block it will get its flow thread from the containing
        block. Once the containing flow thread is requested for the block, the pointer is computed and cached until
        invalidated:
        - when a subtree is removed from a flow thread
        - when the position property of an element inside a flow thread changes

        The process is recursive and it doesn't affect elements that are not nested inside a flow thread. If a block
        changes position from relative to static, any element that was contained by it can only be contained by an
        ancestor of the block. This ancestor will still be outside of any flow thread. This ensures that non-fragmentation
        code is not affected from a performance perspective.

        The patch affects the results of the performance tests:
        - the regions layout tests have a decreased performance raging from 2% to 5-6%
        - the regions selection tests have an increased performance raging from 1-2% to 10%
        - the multicolumn layout tests (now pending review in b137687) have an increased performance
        raging from 1.8% to 5%

        AX: Going back is broken for VoiceOver
        https://bugs.webkit.org/show_bug.cgi?id=137382

        Reviewed by Darin Adler.

        There were two issues preventing VoiceOver from navigating when using page history to go back/forward.
          1) Existing AXLoadComplete does not get fired when you just move through page history. 
               There were existing frameLoad notifications used by GTK. I think we should use those which seem more reliable.
          2) The AccessibilityScrollView cached its children, but on some history page loads, that cache was never cleared out.
               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.

        Tests are not possible since they require monitoring notifications across multiple page loads.

        [Mac] Fix inefficiencies in ResourceResponse::platformLazyInit(InitLevel)
        https://bugs.webkit.org/show_bug.cgi?id=137721

        Reviewed by Geoffrey Garen.

        There were several inefficiencies with the Mac implementation of
        ResourceResponse::platformLazyInit(InitLevel):
        1. We end up initializing uncommon fields even if called with
           'CommonFieldsOnly' initLevel.
        2. If called with 'AllFields' initLevel (and if currently
           uninitialized), we end up populating m_httpHeaderFields twice, once
           with only the common headers, then a second time with ALL the
           headers. We can skip the common-header case in this case to avoid
           wasting CPU time.

        This patch addresses both inefficiencies and cleans up the code a
        little bit to reduce variable scope and to use fast enumeration of
        header names.

        As a result, we spend almost twice as little time in platformLazyInit()
        when loading msn.com (~30ms -> ~18ms).

        Introduce an isCSSAnimated flag on RenderElement for performance
        https://bugs.webkit.org/show_bug.cgi?id=137583

        Reviewed by Simon Fraser.

        I noticed when profiling the ebay.com page load that isRunningAnimationOnRenderer()
        and isRunningAcceleratedAnimationOnRenderer() were called frequently, causing
        ~4.7 millions m_compositeAnimations HashMap lookups.

        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()
          - before: ~45ms  / ~90ms

        Remove the code I added that tracks the timestamp of the most recent

        a silly place to do it and it originally crashed when events were fired from
        Worker threads (although this was fixed in r152238).

        It's now recorded by going through UserGestureIndicator, which is good because
        it knows when a user has triggered an event. Its constructor now takes
        a pointer to Document, and updates the timestamp there if necessary.

        Not all UserGestureIndicator instances needed to reset the timestamp; Those did
        not have to pass along the Document.

        The CG implementation of ImageSource::isSizeAvailable() was looking up
        both the width and the height keys in the dictionary before determining
        if the size is available. We can abort early and return false if the
        first key (the width) is missing, thus avoiding an extra dictionary
        lookup in this case.

        This is a small win but ImageSource::isSizeAvailable() is called quite

        [CSS Grid Layout] Pass the valid set of tracks to grow beyond growth limits
        https://bugs.webkit.org/show_bug.cgi?id=137253

        Reviewed by Darin Adler.

        Section 10.4 of the specs describe how to resolve content based
        track sizing functions. Among others it describes the "distribute
        extra space" algorithm. The 3rd bullet of that algorithm specifies
        how to distribute (and also the target tracks) the extra space
        once all the tracks have reached their growth limits.

        Our implementation had 2 problems. First we were not passing a
        valid subset of tracks (instead we were always using all of
        them). Now we use a function that filters the right tracks to be
        the target of the extra space distribution depending on whether
        we're computing the min track function or the max track function.

        Secondly the algorithm that was distributing the extra space was
        not using that list of passed in tracks (it iterated over all of
        them). From now on it will use the set of tracks selected using
        the filter function described above.

        Update :nth-child(An+B of selector-list) to the latest specification
        https://bugs.webkit.org/show_bug.cgi?id=137593

        Reviewed by Andreas Kling.

        Following my implementation feedback on :nth-child(An+B of selector-list),
        the CSS WG decided to change the definition such that the current element on which
        the selector is matched must also match the selector list in :nth-child().

        This patch updates the implementation accordingly.

        Avoid defaulting to capture-by-value for C++11 lambdas in WebCore
        https://bugs.webkit.org/show_bug.cgi?id=137565

        Reviewed by Darin Adler.

        C++11 lambas should avoid defaulting to capturing used variables by value as that
        can lead to unintended captures that, in worst cases, result in lambdas that are
        not self-contained and end up operating on dangling pointers.

        Explicitly stating the variables that are to be copied by value can also serve as
        a checklist of variables that are actually intented for use in the lambda body.

        MediaPlayer should use a reference for the MediaPlayerClient

        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.

        Add the baseline implementation of :not(selectorList)
        https://bugs.webkit.org/show_bug.cgi?id=137548

        Reviewed by Andreas Kling.

        This patch extend the pseudo class :not() to support the new definition
        in CSS Selectors level 4.

        Instead of supporting a single simple selector, :not() now support
        an arbitrary selector list, excepted pseudo elements.

        One side effect of this change is :visited and :link are no longer supported
        inside :not(). The reason has to do with complexity and performance.
        Since :not() and :matches() can have arbitrary selector list, keeping track of
        :visited and :link can have many combination superposing, some valid, some invalid.

        Supporting :visited and :link should be possible by chaning the way we handle
        them for style resolution, but given the limited use cases for such features
        I'll wait to see if there is any interest before changing everything.

        This patch only covers SelectorChecker to keep things simple. The CSS JIT
        will come later.

        [Mac] Spending too much time mapping desired font families to available ones
        https://bugs.webkit.org/show_bug.cgi?id=137539

        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 justify text in two passes: one counts expansion opportunities within a line,

        This patch simply modifies both passes to descend into ruby bases. Once it has

        On Yosemite there is an animation as a popup menu closes. We can't use
        this when there is a custom rendering, since the animation doesn't match
        the final result. Implement this by hooking into the existing code
        for hiding the arrows during animation - a WebKitSystemInterface update
        will implement the other side.

        [EME][Mac] Update CDMSessionMediaSourceAVFObjC to match new API provided by AVStreamSession

        secure-proof-of-key-release message after the client calls MediaKeySession.close().

        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
        (4.4x less) when loading weather.com.

        The NSOpenGLLayer has to have its contentScale property
        set accordingly when on a retina display. Do this by
        adding another value to the GraphicsContext3D creation
        attribute dictionary, representing the device pixel ratio.
        Then, when we come to draw into the layer, make sure
        we set our GL viewport to the correct value.

        This is currently untestable because:
        - we can't just read from the GL buffer as it is always correct
        - WebGL isn't working in reftests
