We often set mStyleRuleRefreshTime to null to ensure styles get updated.
However, CanThrottleTransformChanges doesn't check for this case and blindly
does subtraction using this value.
Until now we've got away with this but now that we set mStyleRuleRefreshTime to
null when making changes via the API this case crops up in different
circumstances and we can trip over it.
This patch simply adds a null check before using mStyleRuleRefreshTime in
CanThrottleTransformChanges. All other cases where we operate on
mStyleRuleRefreshTime check for null.
Now that CheckNeedsRefresh is a member of the base class,
CommonAnimationManager, we no longer need to rely on callers of
AnimationPlayerCollection::EnsureStyleRuleFor to remember to call this method
but can do it automatically.
In order to add AnimationPlayerCollection::NotifyPlayerUpdated, collections
need a way of updating their managers to inform them that their mNeedsRefreshes
flag has changed and hence the manager may need to resume observing the refresh
driver.
Currently, only nsAnimationManager makes use of mNeedsRefreshes and provides
a CheckNeedsRefresh method. In order to allow AnimationPlayerCollection to
operate independently of the type of manager it is attached to (and because
there's a lot of similar code here that we eventually want to move to a common
manager anyway), this patch moves CheckNeedsRefreshes and associated
machinery to CommonAnimationManager.
I originally wrote this to see if it would fix bug 1086937, but it
didn't.
Note that this conflicts a bit with the patch in bug 1085769; whoever
lands second will have some merging (though it shouldn't be difficult).
The updating of the style rule is needed as part of the animation-only
style update, but it shouldn't be in the general restyling code, so it
has moved there.
This patch extracts the logic for calculating animation styles from
AnimationPlayerCollection and puts the bulk of it into the Animation objects.
Some of the initial logic surrounding the animation player state (e.g. is it
paused or not, etc.) is put into AnimationPlayer.
In future we may shift this logic even further down to the AnimationEffect
objects but currently we don't create such objects unless necessary.
This patch moves code from AnimationPlayerCollection to AnimationPlayer.
However, there is one subtle change in logic involved. Previously, we would test
if the player had finished by getting the computed time of its source content
and checking if it was in the after phase or not. In this patch, however, we
simply check the play state to see if it is finished or not.
These two approaches differ in the case where an animation is paused after it
has finished. The animation phase approach will indicate the player has
finished, but the play state approach will indicate the player has paused (since
the "paused" state trumps the "finished" state). This, however, should not
produce any observable effect because when an animation is paused
mIsRunningOnCompositor will be false (we don't put paused animations on the
compositor).
This patch adds another method to AnimationPlayerCollection alongside
HasCurrentAnimations that returns true if there is a player in the collection
with current source content that targets the specified property.
At the same time it also makes the original HasCurrentAnimations a const method.
It's not the player that's "current" (a Web Animations term for an animation
that hasn't yet finished), but its source content, if any. This patch renames
the method on AnimationPlayer accordingly.
At the same time this patch moves the method to the header file since it's
quite simple and could possibly benefit from inlining.
This (like patch 2) posts restyles directly to the pseudo-element
content nodes, which is a new thing.
This isn't needed right now since AddStyleUpdatesTo is currently only
used when updating main-thread-suppressed animations running on the
compositor. However, it will be needed once we depend on
AddStyleUpdatesTo for bug 960465. And it will have an effect now since
AddStyleUpdatesTo actually adds all animations rather than only the ones
that are suppressed from running on the main thread.
In this fourth step of dividing functionality between AnimationPlayer and
Animation, we move the mIsLastNotification and related methods/enums from
AnimationPlayer to Animation.
It is somewhat unclear where this belongs. This member is used to determine
which event to send for CSS Animations. The thinking behind moving this to
Animation is that if an animation that has already dispatched its animationstart
event was transferred to a new animation player with a similar current time then
I think it is expected that such an animation would *not* dispatch another
animationstart event. That suggests that event-state is a property of the
Animation not the AnimationPlayer.
Obviously, this needs to be defined somewhere (namely, the CSS Animations <->
Web Animations integration spec likely to become "CSS Animations Level 4"). Once
that behavior is agreed upon, if AnimationPlayer proves to be the more suitable
home for this member then it should be relatively straightforward to move the
member back at that time.
As the third step in dividing functionality between AnimationPlayer and
Animation this patch moves the mIsFinishedTransition member and related methods
from AnimationPlayer to Animation.
At the same time we rename SetFinishedTransition to SetIsFinishedTransition.
As the second step in dividing functionality between AnimationPlayer and
Animation, this patch moves the AnimationTiming member from AnimationPlayer to
Animation.
Most of this patch is simply moving code around. However, one significant
functional difference is that Animation::GetLocalTime() uses the mParentTime
member which is set when the Animation is updated by the player it is attached
to.
Other less significant differences are:
* AnimationPlayer::GetLocalTime is renamed to GetCurrentTimeDuration
In Web Animations, animation players have a (writeable) "current time" and
animations have a (read-only) "local time".
We would call the method simply "GetCurrentTime" (instead of
"GetCurrentTimeDuration") but GetCurrentTime is the name of the method used in
the content-facing API where it returns a double.
* "IsCurrent" is defined on both AnimationPlayer and Animation with the version
in AnimationPlayer serving mostly as a convenience shortcut to the version on
Animation.
* Animation::GetComputedTiming (previously on AnimationPlayer) now makes the
timing parameter optional since most of the time it is not needed.
As the first step in dividing the functionality currently contained in
AnimationPlayer between AnimationPlayer and Animation this patch moves the set
of keyframe properties to the Animation.
These properties are returned from the Animation by a couple of Properties()
methods that provide direct access to the member variable. In future it is
anticipated that the non-const version will be replaced with an appropriate
setter function. This will likely happen when we implement a separate
KeyframeEffect object as defined by the Web Animations API.
With regards to error checking, nsAnimationManager checks the result of
AnimationPlayer::GetSource() and handles the case where it is nullptr.
nsTransitionManager, however, simply asserts that GetSource() is never null much
like it also asserts that there is only one property with one segment in the
animation. Eventually this code should be made more generic which will probably
happen in bug 999927.
Now that we have both AnimationPlayer and Animation in use we need to clarify
which object we are referring to. This patch renames a number of member and
local variables to better reflect whether they point to an AnimationPlayer or an
Animation.
This patch is mostly renaming only with one exception. Since we are touching
a number of local variables used in loops (for looping over the array of
animation players) we take the opportunity to replace a number of instances of
uint32_t with size_t since that is the preferred type for array indices now.
This patch makes AnimationPlayers pass their current time down to the Animation
they are playing.
Since all Animations need from their players is their time, this avoids adding
a pointer back to their AnimationPlayer.
This patch renames mozilla::ElementAnimations to mozilla::dom::AnimationPlayer
and moves the code from layout/style/AnimationCommon.cpp to
dom/animation/AnimationPlayer.cpp.
It also moves various helper classes needed by AnimationPlayer to
AnimationPlayer.cpp and moves them from the mozilla::css namespace to the
mozilla namespace.
Beyond that, there are no functional changes contained in this patch.
The renaming of various members and variables that used to refer to
ElementAnimation objects but now refer to AnimationPlayer objects--to give them
a more appropriate name--is performed in a subsequent patch.
--HG--
rename : layout/style/AnimationCommon.cpp => dom/animation/AnimationPlayer.cpp
rename : layout/style/AnimationCommon.h => dom/animation/AnimationPlayer.h
This changes the coalescing behavior during the animation-only style
flush by doing tree-based coalescing between the style updates required
by animations and those required by transitions, rather than doing
animations and transitions separately.
Note that both the old and the new code update all
animating/transitioning styles rather than only the throttled styles,
though we should fix that eventually as noted in the FIXME comment in
the code (but only for the existing caller, and not for the new one to
be introduced in bug 960465).
Note that this depends for its correctness on the previous patches to
make the restyling process exact.
The test changes are because the effects of bug 1031688 are changed by
the change in coalescing. In the old code, we updated transition styles
before animation styles; in the new code we do a single pass over the
tree, which for the relevant test means updating animations on the
parent before transitions on the child, which changes the effects of the
bug.

This means ResolveStyleWithReplacement will replace only the rules in
the nsRestyleHint rather than always replacing both the animations rule
and the transitions rule. (This will become even more useful later when
we add the ability to replace the style attribute rule.)
A document that belongs to an iframe that is display:none as no associated pres
context from which to get a refresh driver. However, in this case
document.timeline.currentTime should still never go backwards (since document
timelines are supposed to be monotonically increasing).
This patch makes AnimationTimeline record the last value returned for the
current time so that if the document becomes display:none we can still return
the most recently used time.
This patch introduces a method GetComputedTiming that calls GetComputedTimingAt
supplying the current time of the animation's timeline.
We still keep the GetComputedTimingAt static method since it is used for
off-main thread animation. Furthermore, we keep the second argument to
GetComputedTiming--the animation's timing properties--since on some occasions we
want to override those properties (ElementPropertyTransition::ValuePortionFor
does this). We could also add another overload that also supplies the
animation's timing properties but that can happen as a separate step.
This patch changes ElementAnimation::GetLocalTimeAt so that instead of taking
the current time as input, it uses the animation's mTimeline member to look up
the current time of the associated timeline. As a result of this, it is possible
to remove a few instances of querying the refresh driver for the current time.
Further instances are removed in subsequent patches.
Furthermore, in order to keep the use of time sources consistent, the mStartTime
of new transitions and animations is initialized with the current time from the
animation's timeline rather than with the latest refresh driver tick.
Since this time could, in future, be null, GetLocalTime(At) is updated to check
for a null start time.
GetLocalTimeAt is also renamed to GetLocalTime in the process.
Once we support arbitrary timelines which can return null current time values,
the local time of an animation can also become null so this patch updates
ElementAnimation::GetLocalTimeAt to return a Nullable<TimeDuration>.
Doing this also allows us to pass the result of GetLocalTimeAt directly to
GetComputedTimingAt.
As part of supporting arbitrary timelines, we'd like to pass null times to the
function that calculates computed timing. Incidentally, this also provides
a means for evaluating calculating timing parameters that are independent of the
current time (currently only the active duration) without requiring a valid
time.
This patch updates the signature of ElementAnimation::GetComputedTimingAt to
take a nullable time duration.
We use the Nullable wrapper to represent null TimeDurations since, unlike,
TimeStamp, TimeDuration does not include a null state.
This patch adds the WebIDL definitions and implementation of
getAnimationPlayers on Element.
It does not include the full definition of AnimationPlayer but only readonly
versions of the currentTime and startTime attributes since these are easy
to implement and enable identifying the different animations that are returned
for the sake of testing.
Web Animations defines getAnimationPlayers as only returning the animations that
are either running or will run in the future (known as "current" animations).
This will likely change since it seems desirable to be able query animations
that have finished but are applying a forwards fill. For now, however, this
patch makes us only return animations that have not finished.
This patch also removes an assertion in ElementAnimation::GetLocalTime that
would fail if called on a finished transition. This assertion is no longer
necessary since an earlier patch in this series removed the overloading of
the animation start time that meant calling this on a finished transition
was unsafe. Furthermore, this assertion, if it were not removed, would fail
if script holds onto a transition and queries its start time after it
completed.
When we expose ElementAnimation objects to script they need to have a parent
object so they can be associated with a Window.
This patch adds a pointer from an ElementAnimation to its AnimationTimeline.
When transitions finish, we keep them around for one additional throttle-able
tick to provide correct behavior for subsequent transitions that may be
triggered. Prior to this patch we did this by overloading the start time of the
animation and setting it to null in this case.
However, if we begin returning ElementAnimation objects to script, script can
hold on to those objects and query their start time even after they are
finished. Therefore we need another means of marking finished transitions that
doesn't clobber the start time field.
This patch introduces a new boolean member for marking such transitions.
While we're touching IsFinishedTransition we also take the chance to tidy up one
of the call sites, namely IsCurrentAt, to make the logic a little easier to
follow.
This patch makes the active duration a property of the ComputedTiming struct and
returns this as part of calculating GetComputedTimingAt. GetComputedTimingAt was
already calling the method to calculate the ActiveDuration and the only other
callers of ActiveDuration() were also calling GetComputedTimingAt so this
doesn't make us do any unnecessary calculation.
I've left ActiveDuration as a public method on ElementAnimation for now since
it's a struct and just about everything there is public. At some point in the
future we'll probably make this more class-like to hide some details but that
can happen as a separate step. This patch does, however, move the definition of
ActiveDuration inside the .cpp file.
In tidying up GetComputedTimingAt we also replace all the references to
TimeDuration() and TimeDuration(0) with a single local variable representing
zero duration. This should be easier to read and possibly a little faster.
We don't use a function static variable since this method is called from
different threads and the initialization of function statics is not guaranteed
to be thread-safe until C++0x.
In TimeStamp_windows.cpp and TimeStamp_darwin.cpp, in
TimeStamp::FromMilliseconds we cast the floating-point number of ticks to
a 64-bit integer before passing to TimeStamp::FromTicks(int64_t).
This means that we skip the check for integer overflow performed by
TimeStamp::FromTicks(double).
This patch simply removes that cast so that we perform overflow checking.
It also adds an assertion to ElementAnimation since this is one place where
the lack of overflow checking was producing a negative value where it should
not.
This patch also moves the static methods defined on nsStyleAnimation so that
they are part of StyleAnimationValue class.
Renaming nsStyleAnimation.h to StyleAnimationValue.h is performed in a separate
patch to simplify the diff (since some tools may not handle file renames
elegantly).
This patch takes the two static methods ElementAnimationsPropertyDtor and
ElementTransitionsPropertyDtor and replaces them with a class static on
CommonElementAnimationData.
This patch removes ElementAnimations and replaces all references to
ElementAnimations with references to CommonElementAnimationData.
We don't bother to rename variables like 'ea' or methods like
GetElementAnimations to correspond with the data type
(CommonElementAnimationData) since CommonElementAnimationData will soon be
renamed in bug 1010067 and we'll rename these things then.
The ElementAnimationsPropertyDtor function is renamed and merged in a subsequent
patch in this series.
This patch replaces all references to ElementTransitions (now that it is empty)
with references to the base class, CommonElementAnimationData. It also takes the
opportunity to tidy up some of the call sites in nsLayoutUtils since they no
longer need to differentiate between animations and transitions.
A previous patch moved CanPerformOnCompositorThread to
CommonElementAnimationData including a FIXME saying that active layer
notification should happen at call sites. Now that the code for
GetAnimationsForCompositor is common, we can do the active layer notification
there.
This patch still leaves ElementAnimations|
ElementTransitions::GetAnimationsForCompositor as shortcuts
for the method now defined on CommonElementAnimationData.
This patch moves HasAnimationOfProperty to CommonElementAnimationData. It also
takes the chance to start removing some redundancy from nsLayoutUtils
/ ActiveLayerTracker. Some of this should never have been added in the first
place and some could have been removed earlier on but while we're fixing up
HasAnimationOfProperty it seems like an appropriate time to fix up its call
sites too.
Also, since HasAnimationOrTransition actually returns an object, not a bool, we
this patch renames it to GetAnimationsOrTransitions.
In a number of places in nsAnimationManager we have the following sequence of
calls:
CommonElementAnimationData::EnsureStyleRuleFor
ElementAnimations::GetEventsAt
nsAnimationManager::CheckNeedsRefresh
nsAnimationManager::EnsureStyleRuleFor already does exactly that so we should
just reuse it.
At the same time we rename EnsureStyleRuleFor to UpdateStyleAndEvents since
that's a bit more accurate. It's also confusing to have two methods of the same
name (but on different objects) that don't exactly correspond in terms of
the scope of what they do.
Both ElementAnimations and ElementTransitions have an EnsureStyleRuleFor method.
The ElementAnimations version is a more general of the ElementTransitions one
with the exception that the ElementTransitions version checks for finished
transitions. This patch moves the code from ElementAnimations to
CommonElementAnimationData with one minor change: adding the checks for finished
transitions. The ElementTransitions version is removed.
Since the ElementAnimations version contains a second parameter, aIsThrottled,
callers of ElementTransitions must include this extra parameter. In
a subsequent patch we add an enum for this parameter to make call sites easier
to read.
The ElementAnimations version also sets the mNeedsRefreshes member so at the
same time we move mNeedsRefreshes to CommonElementAnimationData. Furthermore,
since the ElementAnimations version which we have adopted returns early if
mNeedsRefreshes is false, this patch ensures that when we call
EnsureStyleRuleFor from ElementTransitions::WalkTransitionRule, we set
mNeedsRefreshes to true first.
Another difference to account for is that the ElementTransitions version of
EnsureStyleRuleFor *always* sets mStyleRule (even if it doesn't add anything to
it) where as the ElementAnimations version only creates the rule when necessary
so we need to add a check to ElementTransitions::WalkTransitionRule that
mStyleRule is actually set before using it.
Now that an animation's delay is part of AnimationTiming--the struct we pass to
GetComputedTimingAt--it makes sense to act on it in GetComputedTimingAt.
This also happens to bring the procedures here closer to the algorithm
definitions in Web Animations.
As part of this refactoring, this patch converts ElementAnimation::IsRunningAt
to use GetComputedTiming since the previous approach no longer works now that
GetLocalTimeAt (nee ElapsedDurationAt) no longer handles delays. This also
removes duplicated logic.
Also, previously ElapsedDurationAt would assert if called on a finished
transition since TimeDuration's - operator wouldn't like the null mStartTime.
This patch adds an assertion for this case to GetLocalTimeAt to ease debugging.
One of the main differences in handling a list of transitions vs a list of
regular animations is that when we are dealing with a list of transitions we
need to check for transitions that have finished and are about to be discarded
but need to be retained temporarily to provide correct triggering of subsequent
transitions. Such transitions are marked as "removed sentinels" and are ignored
for most operations.
This patch moves the methods for setting and checking such transitions to the
base class ElementAnimation so that we can treat animations and transitions
alike without having to downcast or do obscure checks for mStartTime.IsNull()
(which equates to checking if the animation is a "removed sentinel" but is not
particularly clear).
In the process, this patch renames said methods to Is/SetFinishedTransition
since hopefully that is a little easier to understand at a glance.
This patch adjusts GetComputedTimingAt to set the time fraction and current
iteration fields of the output computed timing correctly for animations with
zero iteration duration. Care must be taken to handle cases such as animations
that have zero duration but repeat infinitely.
The code is significantly re-arranged to more closely align with the naming and
algorithms defined in Web Animations.
A couple of tests in test_animations.html have been tweaked to account for
floating-point error. This is not because the new code is less precise but
actually the opposite. These tests fall on the transition point of step-timing
functions. The new code uses the closest possible floating-point representation
of these times which happens to cause them to fall on the opposite side of the
transition point.
For example, in evaluating a point 3s into a reversed interval the old code
would give us an intermediate time fraction of:
0.29999999999999982
When we reverse that by subtracting from 1.0 we get: 0.70000000000000018
With the code in this patch we get an intermediate time fraction of:
0.29999999999999999
When we reverse that by subtracting from 1.0 we get: 0.69999999999999996
Hence we fall on the opposite side of the transition boundary.
This patch also makes ElementAnimation::ActiveDuration a static method that
takes timing parameters as an argument. This is so that this method can be
used within ElementAnimations::GetComputedTimingAt (a static method) in a
future patch.
We could also make ActiveDuration() a method of AnimationTiming. I suspect
this logic belongs together in ElementAnimation however.
In a future patch we could also add the active duration to the ComputedTiming
struct which would simplify the only other place this is currently used
which is ElementAnimations::GetEventsAt.
This patch simply moves the code from ElementAnimations to ElementAnimation so
that it can later be used in transitions code and so we can later move
EnsureStyleRuleFor to ElementAnimation.
Introduces a struct to store timing parameters for passing to
GetPositionInIteration. In future this struct is expected to be expanded to
include other timing parameters as well (based roughly on Web Animations'
"Timing" interface, hence the name AnimationTiming).
We currently have mozilla::StyleAnimation as well as nsStyleAnimation. This
patch renames StyleAnimation back to ElementAnimation.
Although ElementAnimation is very similar to ElementAnimations, in the near
future we expect to retire ElementAnimations and replace it with a common
AnimationSet-like structure that is covers the features of ElementAnimations and
ElementTransitions.
We need a basic representation of animations from which we can derive subclasses
to represent specific cases such as transitions. For now we will retrofit
ElementAnimation for that purpose hence renaming it to StyleAnimation.
This patch removes the "using namespace mozilla::layers" line from
AnimationCommon.cpp since the unified build system concatenates several files
together before compiling making using declarations like this leak into other
files potentially creating ambiguities. Previously, when we were calling
ElementAnimation, 'Animation', there were ambiguities between
mozilla::layers::Animation and this new 'Animation' class. In general, it is
probably a good idea to limit the scope of these using declarations so I've kept
that change.
This patch relocates ElementAnimation from nsAnimationManager.{h,cpp} to
AnimationCommon.{h,cpp} and in the process moves it into the mozilla::css
namespace.
I've been wanting to remove this code for a while. I think this code is
problematic for three reasons:
(1) It's in the middle of code where it doesn't belong, and which ought
to be handling purely-style-system things. (This is blocking me
from reusing that code elsewhere, e.g., in bug 977991 and
bug 960465, both of which could use it in some form.)
(2) It defeats the optimization from bug 790505 whenever we do a
miniflush (in other words, whenever we have any style change,
whether or not it's related)
(3) It means the conditions for when we decide to ship a new set of
animation data to a layer doesn't cover all the cases the layer
needs it. In particular, we only run this miniflush code when we
have a currently running animation or transition that's running on
the compositor thread. On the other hand, the UpdateTransformLayer
style change handling in DoApplyRenderingChangeToTree depends on
whether the frame currently has a transform layer, which can
continue to be true for a bit after the animation stops. So if we
need to send animations to the layer because of a transform style
change that happens soon after an animation completes, our style
change handling will find the existing layer and call its
SetBaseTransformForNextTransaction method but never do anything
that triggers layer construction. The style throttling code, in
turn, will never stop doing main thread updates because the
animation generation on the layer is out-of-date, and these main
thread updates will keep the layer active, but they'll never show
up because the stale animation data overrides the new transform
that we've been setting. (At least, I think that's what was
happening; it makes sense to me and matches the behavior I was
observing. I didn't verify which main thread updates and which
layer updates were actually happening, though.)
This shows up, for example, in the animation in attachment 8384813
just halting at a corner if I'm careful not to disturb it. (I'm
testing on Linux, with both accelerated layers and OMT animations
explicitly enabled.)
I think there are probably some other things that can be removed as
followups to removing this code, because I think we made some boundary
conditions intentionally incorrect so that problem (3) above wouldn't be
as bad as it otherwise would have been.
This moves restyling management out of nsCSSFrameConstructor (thus
reducing its size), and keeps the restyling code closer together.
This is the first of two big chunks of code moved in this patch series.
A later patch in this series will move related code from nsFrameManager
into the same destination file.
The fixes to the miniflush code
(nsTransitionManager::UpdateThrottledStyle and UpdateAllThrottledStyles)
fix the case where we constructed totally incorrect style contexts for
outer table frames (which have special style contexts inheriting from
the table frame) during the miniflush, leading to inconsistent style
data and other bad things, when we should have been touching the style
on the table frame instead.
The fixes to the other OMTA codepaths lead to layer tests being
performed on the same frame that the styles will be applied to, and
probably fix real bugs (which would occur when animating opacity or
transform on a table).
