This is a temporary preference to allow for testing-in-the-wild by a larger
audience, for nightly builds. When 1177263 is fixed this can be removed.

After this change, we have PLDHashTable::ShallowSizeOf{In,Ex}cludingThis(),
which don't do anything to measure children. (They can be combined with
iteration to measure children.)
This patch also removes the PL_DHashTableSizeOf{In,Ex}cludingThis() functions.
They're not necessary because the methods can be used instead.
Finally, the patch deliberately converts some SizeOfExcludingThis() calls to
SizeOfIncludingThis(). These are all done on heap pointers so this change is
valid.

Bug 960465 (specifically part 6, changeset 7d16f2fd8329) changed the way we
process animation-only style changes. This caused us to update SMIL animations
more often than is needed.
This patch adjusts this behavior to update the style from SMIL animations less
frequently by tracking when animated values have been composited without adding
the corresponding changes to a restyle tracker.
When the refresh driver ticks it clears the RAF callbacks (content asks for another RAF if it desires) but it wasn't checking if it should exit high precision mode at this point.
The previous code seemed like it was using the wrong model that a RAF is persistent until it is revoked. But that is not the case.
This makes it clearer that, unlike how SizeOf*() functions usually work, this
doesn't measure any children hanging off the array.
And do likewise for nsTObserverArray.

AppendScrollPartsTo finds or creates a scroll id for the current scroll frame if IsMaybeScrollingActive() is true (otherwise it uses the null scrollid). IsMaybeScrollingActive() looks at mShouldBuildScrollableLayer, which we compute after the first call to AppendScrollPartsTo in ScrollFrameHelper::BuildDisplayList.
This means that on the first paint with a displayport set (or even if we create a displayport is ScrollFrameHelper::BuildDisplayList) we wouldn't layerize the scroll thumb in nsSliderFrame::BuildDisplayListForChildren because it looks for the current scroll id set on the display list builder. On subsequent paints this would be corrected so it caused reftest failures.
This patch causes transition events to be dispatched as a separate step after
sampling the transitions. Eventually this will allow us to sample transitions
from their timeline (independently of where they came from and in potentially
any order) by separating the concepts of sampling and event dispatch.
This patch moves the logic for queueing events out of the logic for flushing
transitions making it a separate step. It still doesn't delay the dispatch of
those events into a separate step, however. That is done in a subsequent patch.
This patch also makes sure to clear any queued events when the nsPresShell that
owns the transition manager is destroyed. We don't expect CSSTransition::Tick to
be called anywhere except nsTransitionManger::FlushTransitions so there
shouldn't be any orphaned events but for completeness it seems best to add this
now. (Later, when we tick transitions from their timeline we will need this.)
This patch introduces a separate flag to CSSTransition for tracking if a
transition is newly-finished so we can correctly dispatch the transitionend
event. Although, this may seem to be redundant with the "IsFinishedTransition"
we also track, that state will soon be removed in bug 1181392 and hence this
flag will be needed then.
Note that Animation already has flags mIsPreviousStateFinished and
mFinishedAtLastComposeStyle which would appear to be similar however,
- mIsPreviousStateFinished will be removed in bug 1178665 and is updated more
often than we queue events so it is not useful here.
- mFinishedAtLastComposeStyle is used to determine if we can throttle a style
update and is also updated more frequently than we queue events and hence
can't be used here.
Once we guarantee one call to Tick() per frame we may be able to simplify this
by tracking "state on last tick" but for now we need this additional flag on
CSSTransition. CSSAnimation has a similar flag for this
(mPreviousPhaseOrIteration) which we may be able to unify at the same point.
This simply uses the DelayedEventDispatcher in place of the previous array of
TransitionEventInfo objects. Doing the actual delayed dispatch is performed in
a separate patch.
Prior to this patch, CSSAnimation defined a method for converting an
nsCSSPseudoElements::Type to a nsString (but only for the set of
pseudo-elements that can have animations). We would like to re-use this
when setting up transition events so this patch moves it to
AnimationCollection. Re-using this method more widely means we can make
a few further simplifications to the code.
This patch extracts a utility class for queueing up a series of EventInfo
objects (of templated type) and then dispatching them. This covers the event
queuing behavior in nsAnimationManager so that we can reuse it in
nsTransitionManager.
The long-term plan is to drop the mozilla::css namespace altogether. Before we
go to much further with refactoring code in AnimationCommon, we should drop
usage of the mozilla::css namespace. Specifically, this patch moves the
CommonAnimationManager and AnimValuesStyleRule classes to the mozilla namespace.
This patch prepares the way for script-generated events by making
event dispatch a separate process that happens after sampling animations.
This will allow us to sample animations from their associated timeline
(removing the need for a further manager to tracker script-generated
animations).
Furthermore, once we sample animations from timelines the order in which they
are sampled is likely to be more or less random so by making event dispatch at
separate step, we have an opportunity to sort the events and dispatch in
a consistent and sensible order. It also ensures that event callbacks will
not be run until all animations (including transitions) have been updated
ensuring they see a consistent view of timing properties.
This patch only affects event handling for CSS animations. Transitions will
be dealt with in a subsequent patch.
There was a bug introduced in to animation_utils.js in
https://hg.mozilla.org/mozilla-central/rev/496e867cd2cd (bug 1070745). This
patch fixes this bug so we can be sure testing events correctly before messing
with them.
Without this change, nsBlockFrame::ReflowBlockFrame will fail to have
mayNeedRetry true, which means that it won't set
blockHTMLRS.mDiscoveredClearance, which means that on a descendant
replaced block we will fail to fall into any of the cases that call
ClearFloats. This change will cause us to hit the first ClearFloats
call and discover the need for clearance.
I tested locally that the new reftest fails without the patch and passes
with the patch.
