Note that this means that when we start transitions, we post restyles that are processed during the current restyling operation, rather than in a later phase. This depends on patch 11, which makes the transition manager skip style changes that it posts while starting transitions, to ensure that this doesn't lead to an infinite loop. This also depends on patch 16, which only consumes restyle data for the primary frame, to ensure that the animation restyles posted are processed properly. It also depends on patch 14, which makes us retain data on finished transitions, to avoid triggering extra transitions on descendants when both an ancestor and a descendant transition an inherited property, and the descendant does so faster. This fixes a known failure in layout/style/test/test_animations.html and test_animations_omta.html (as visible in the patch). I believe this is because this patch changes us to compute keyframe values for animations on top of a style context *with* animation data rather than one without, which means what we're computing them on top of changes each time. (The purpose of patch 3 was to avoid this in the case where avoiding it matters, i.e., implicit 0% and 100% keyframes.)

/**
|
|
* Helper methods for the type-specific WillChangeXXX methods.
|
|
*
|
|
* This method sends out appropriate pre-change notifications so that selector
|
|
* restyles (e.g. due to changes that cause |elem[attr="val"]| to start/stop
|
|
* matching) work, and it returns an nsAttrValue that _may_ contain the
|
|
* attribute's pre-change value.
|
|
*
|
|
* The nsAttrValue returned by this method depends on whether there are
|
|
* mutation event listeners listening for changes to this element's attributes.
|
|
* If not, then the object returned is empty. If there are, then the
|
|
* nsAttrValue returned contains a serialized copy of the attribute's value
|
|
* prior to the change, and this object should be passed to the corresponding
|
|
* DidChangeXXX method call (assuming a WillChangeXXX call is required for the
|
|
* SVG type - see comment below). This is necessary so that the 'prevValue'
|
|
* property of the mutation event that is dispatched will correctly contain the
|
|
* old value.
|
|
*
|
|
* The reason we need to serialize the old value if there are mutation
|
|
* event listeners is because the underlying nsAttrValue for the attribute
|
|
* points directly to a parsed representation of the attribute (e.g. an
|
|
* SVGAnimatedLengthList*) that is a member of the SVG element. That object
|
|
* will have changed by the time DidChangeXXX has been called, so without the
|
|
* serialization of the old attribute value that we provide, DidChangeXXX
|
|
* would have no way to get the old value to pass to SetAttrAndNotify.
|
|
*
|
|
* We only return the old value when there are mutation event listeners because
|
|
* it's not needed otherwise, and because it's expensive to serialize the old
|
|
* value. This is especially true for list type attributes, which may be built
|
|
* up via the SVG DOM resulting in a large number of Will/DidModifyXXX calls
|
|
* before the script finally finishes setting the attribute.
|
|
*
|
|
* Note that unlike using SetParsedAttr, using Will/DidChangeXXX does NOT check
|
|
* and filter out redundant changes. Before calling WillChangeXXX, the caller
|
|
* should check whether the new and old values are actually the same, and skip
|
|
* calling Will/DidChangeXXX if they are.
|
|
*
|
|
* Also note that not all SVG types use this scheme. For types that can be
|
|
* represented by an nsAttrValue without pointing back to an SVG object (e.g.
|
|
* enums, booleans, integers) we can simply use SetParsedAttr which will do all
|
|
* of the above for us. For such types there is no matching WillChangeXXX
|
|
* method, only DidChangeXXX which calls SetParsedAttr.
