+
+ Crash due to SVG animation element not removed from target (before reset)
+ https://bugs.webkit.org/show_bug.cgi?id=90750
+
+ Reviewed by Abhishek Arya.
+
+ Previously we were not removing an animation element from
+ SVGDocumentExtensions::m_animatedElements which led to a crash.
+ This change properly removes animation elements in resetTargetElement
+ which both fixes this bug and will prevent others from hitting it in
+ the future.
+
+ Test: svg/animations/dynamic-modify-attributename-crash2.svg
+
+ * svg/SVGDocumentExtensions.cpp:
+ (WebCore::SVGDocumentExtensions::removeAllAnimationElementsFromTarget):
+
+ removeAllAnimationElementsFromTarget now adds all the animation elements
+ to a vector and iterates over it because the changes to resetTargetElement
+ would have caused us to modify the underlying hashset as we iterated. Note that
+ before we deleted animationElementsForTarget in removeAllAnimationElementsFromTarget
+ but that logic is now handled in removeAnimationElementFromTarget which is called
+ during resetTargetElement.
+
+ * svg/animation/SVGSMILElement.cpp:
+ (WebCore::SVGSMILElement::removedFrom):
+
+ Because of the changes in resetTargetElement, removedFrom was able to be
+ refactored. This patch changes removedFrom to call resetTargetElement rather
+ than have duplicated logic. There is a very small change in logic here:
+ animationAttributeChanged() is now called in removedFrom().
+
+ (WebCore::SVGSMILElement::resetTargetElement):
+
+ resetTargetElement now fully resets the target, including removing it from
+ m_animatedElements. This will prevent future instances of this bug.
