Remove the legacy animation code https://bugs.webkit.org/show_bug.cgi?id=216608 Reviewed by Dean Jackson. Source/WebCore: We remove the legacy animation code found in Source/WebCore/page/animation/, save for CSSPropertyAnimation which is also used by the new Web Animations engine and now moved to Source/WebCore/animation/. Since we now have a single animation engine, the runtime flags to optionally enable the Web Animations engine are not needed anymore and removed as well. We also remove some testing utilities and some RenderLayerBacking methods specific to accelerated transitions which the new animation engine does not use. * CMakeLists.txt: * Headers.cmake: * Sources.txt: * WebCore.xcodeproj/project.pbxproj: * animation/Animatable.idl: * animation/AnimationEffect.idl: * animation/AnimationPlaybackEvent.idl: * animation/AnimationPlaybackEventInit.idl: * animation/AnimationTimeline.idl: * animation/CSSAnimation.idl: * animation/CSSPropertyAnimation.cpp: Renamed from Source/WebCore/page/animation/CSSPropertyAnimation.cpp. (WebCore::PropertyWrapperVisitedAffectedColor::PropertyWrapperVisitedAffectedColor): * animation/CSSPropertyAnimation.h: Renamed from Source/WebCore/page/animation/CSSPropertyAnimation.h. * animation/CSSTransition.idl: * animation/DocumentAnimations.idl: * animation/DocumentOrShadowRootAnimations.idl: * animation/DocumentTimeline.idl: * animation/KeyframeEffect.idl: * animation/WebAnimation.idl: * animation/WebAnimationTypes.h: * css/CSSComputedStyleDeclaration.cpp: (WebCore::computeRenderStyleForProperty): * dom/Document.cpp: (WebCore::Document::resolveStyle): (WebCore::Document::didBecomeCurrentDocumentInFrame): (WebCore::Document::willBeRemovedFromFrame): (WebCore::Document::implicitClose): (WebCore::Document::resume): * dom/Element.cpp: (WebCore::Element::removedFromAncestor): * dom/PseudoElement.cpp: (WebCore::PseudoElement::clearHostElement): * history/CachedFrame.cpp: (WebCore::CachedFrame::destroy): * page/Frame.cpp: (WebCore::Frame::Frame): (WebCore::Frame::clearTimers): (WebCore::Frame::resumeActiveDOMObjectsAndAnimations): * page/Frame.h: * page/FrameView.cpp: (WebCore::FrameView::didDestroyRenderTree): (WebCore::FrameView::updateLayoutAndStyleIfNeededRecursive): * page/FrameViewLayoutContext.cpp: (WebCore::FrameViewLayoutContext::layout): * page/Page.cpp: (WebCore::Page::handleLowModePowerChange): (WebCore::Page::setIsVisibleInternal): (WebCore::Page::hiddenPageCSSAnimationSuspensionStateChanged): * page/RuntimeEnabledFeatures.h: (WebCore::RuntimeEnabledFeatures::setWebAnimationsEnabled): Deleted.

[Web Animations] Querying the current time of a finished CSSAnimation after removing its target leads to a crash https://bugs.webkit.org/show_bug.cgi?id=187906 Reviewed by Dean Jackson. Source/WebCore: Test: webanimations/accessing-current-time-after-finished-css-animation-target-removal.html Because we carelessly look at a CSSAnimation's effect's timing in DeclarativeAnimation::bindingsCurrentTime without checking that the effect is non-null, we can crash in the case where the animation is finished and its target element has been removed, which caused the effect to be set to null. We do not actually fix the lack of a null check, which will be the scope of a different patch, but instead ensure that we do _not_ set the animation's effect to null when its target is removed, which used to be performed via a call to WebAnimation::remove(). Instead, we introduce AnimationTimeline::elementWasRemoved() which notifies the timeline of an element being removed such that we may stop referencing any animation targeting this element from the various data structures holding strong references to the animation in question, and we then cancel the animation silently, which is a new option that ensures promises aren't resolved or rejected as a result. Finally, the WebAnimation and AnimationEffectReadOnly classes established a ref-cycle as WebAnimation has `RefPtr<AnimationEffectReadOnly> m_effect` and AnimationEffectReadOnly has `RefPtr<WebAnimation> m_animation`. While it is correct that WebAnimation owns its effect, which is established by the DOM API, the reverse is not correct since we only hold the reverse internally for the benefit of our implementation. As such, we change AnimationEffectReadOnly's m_animation to be a WeakPtr<WebAnimation>. This means not calling WebAnimation::remove() and simply removing the animation from the animation maps on the timeline is sufficient to guarantee that the document timeline will not leak (and with it the document). * animation/AnimationEffectReadOnly.h: (WebCore::AnimationEffectReadOnly::setAnimation): * animation/AnimationTimeline.cpp: (WebCore::AnimationTimeline::elementWasRemoved): * animation/AnimationTimeline.h: * animation/WebAnimation.cpp: (WebCore::WebAnimation::cancel): (WebCore::WebAnimation::resetPendingTasks): * animation/WebAnimation.h: * dom/Element.cpp: (WebCore::Element::removedFromAncestor): * rendering/updating/RenderTreeUpdater.cpp: (WebCore::RenderTreeUpdater::tearDownRenderers): LayoutTests: Add a new test that checks the behavior of a CSSAnimation instance after its completion and removal of its target. * webanimations/accessing-current-time-after-finished-css-animation-target-removal-expected.txt: Added. * webanimations/accessing-current-time-after-finished-css-animation-target-removal.html: Added.
