Source/JavaScriptCore:

We previously did not handle Spread(PhantomCreateRest) only because I did not
think it was possible to generate this IR. I was wrong. We can generate
such IR when we have a PutStack(Spread) but nothing escapes the CreateRest.
This IR is rare to generate since we normally don't PutStack(Spread) because
the SetLocal almost always gets eliminated because of how our bytecode generates
op_spread. However, there exists a test case showing it is possible. Supporting
this IR pattern in FTLLower is trivial. This patch implements it and rewrites
the Validation rule for Spread.

Pressing the space bar while watching a fullscreen video doesn't play or pause

Patch by Antoine Quint <Antoine Quint> on 2017-11-27
Reviewed by Eric Carlson.

Source/WebCore:

We register a "keydown" event to track when the space bar is pressed, and if the media is playing
in fullscreen, we toggle playback. This does not interfere with full keyboard access since activating
one of the media controls using the keyboard will not let the events we register for be dispatched
this far along the event dispatch phase.

webkitpy: Better name-version mapping (Part 1)
​https://bugs.webkit.org/show_bug.cgi?id=179621
<rdar://problem/35589585>

Reviewed by David Kilzer.

Mapping version numbers to version names should occur in a central location.
This has a few advantages. First, it makes iterating through versions easier.
Second, it allows for apple_additions to define an additional set of name
mappings. Lastly, it will allow, in a future patch, for us to track version
instead of version name, only mapping version to version name when required.

ASSERTION FAILED: addResult.isNewEntry WebCore::SWServerRegistration::addClientUsingRegistration(WebCore::ServiceWorkerClientIdentifier const&) + 141
​https://bugs.webkit.org/show_bug.cgi?id=180049

Reviewed by Brady Eidson.

Source/WebCore:

SWServer::serviceWorkerStoppedControllingClient() was failing to remove the client from the
SWServerRegistration in some cases. This is because we relied on the Service Worker Identifier
to get the SWServerRegistration, via the corresponding SWServerServiceWorker object. However,
It is possible for the SWServerServiceWorker to have been destroyed already.

In serviceWorkerStartedControllingClient / serviceWorkerStoppedControllingClient, we now
pass the registration identifier, so that we are able to look up the registration directly,
without going through the service worker object.

No new tests, already covered by imported/w3c/web-platform-tests/service-workers/service-worker/claim-affect-other-registration.https.html.

Because those cases, WKWebView should test before downcasting to WebKit::FullscreenClient.

Reviewed by Sam Weinig.

Source/WebCore:

Implement enough of getContext("webgl") to actually return an
active WebGLRenderingContext, even though it isn't actually
hooked up to draw.

Introduce a new type, WebGLCanvas, which is a variant of HTMLCanvasElement
and OffscreenCanvas, so that it can be exposed by the 'canvas' attribute
on WebGLRenderingContext.

At the moment we still assume that all uses of WebGLRenderingContext come
from HTMLCanvasElement, so add a bunch of logic to detect that case.

[CoordGraphics] Prettify ID value handling in UpdateAtlas and UpdateAtlas::Client
​https://bugs.webkit.org/show_bug.cgi?id=180038

Reviewed by Carlos Garcia Campos.

In the UpdateAtlas class, provide an ID type that aliases to uint32_t.
The m_id member variable (ex-m_ID) uses this type, and it's also now
used in the Client interface.

While poking around, the header is modified to use '#pragma once',
and m_id is moved to the more logical first position among member
variables.

The static ID variable is modified to use the new type, and renamed
to s_nextID. Comment alongside the namespace scope closure is fixed
to use the appropriate name.

createUpdateAtlas() and removeUpdateAtlas() methods in the
CompositingCoordinator class are modified to use the UpdateAtlas::ID
type, and the former has the second parameter changed from RefPtr<>
to Ref<>.

Pressing the space bar while watching a fullscreen video doesn't play or pause

Source/WebCore:

We register a "keydown" event to track when the space bar is pressed, and if the media is playing
in fullscreen, we toggle playback. This does not interfere with full keyboard access since activating
one of the media controls using the keyboard will not let the events we register for be dispatched
this far along the event dispatch phase.

We have an utility function to compute the grid item's margins
when the item still needs to layout. We used the function
RenderStyle::hasMarings to decide whether such margin computation
worths. However, we need that function to operate on a specific
axis, hence I added a new function adding such logic.

Additionally, we must treat any 'auto' margin as 0px during the
tracks sizing algorithm, as the CSS Grid spec states:

[DFG] Add NormalizeMapKey DFG IR

Source/JavaScriptCore:

This patch introduces NormalizeMapKey DFG node. It executes what normalizeMapKey does in inlined manner.
By separating this from MapHash and Map/Set related operations, we can perform CSE onto that, and we
do not need to call normalizeMapKey conservatively in DFG operations.
This can reduce slow path case in Untyped GetMapBucket since we can normalize keys in DFG/FTL.

Source/JavaScriptCore:

We should increase the coverage of FTL. Even if the code includes DeleteById,
it does not mean that remaining part of the code should not be optimized in FTL.
Right now, even CallEval and with scope are handled in FTL.

This patch just adds DeleteById and DeleteByVal handling to FTL to allow optimizing
code including them.

feImage as filter input has skewed colors
​https://bugs.webkit.org/show_bug.cgi?id=180021

Reviewed by Sam Weinig.
Source/WebCore:

Using an <feImage> as a filter input sometimes results in incorrect colors, because
the image is being sourced as linearRGB when it should always be sRGB.

Fix by setting the result colorspace in FEImage before we allocate the output
buffer.

Fix CLoop::sanitizeStack() bug where it was clearing part of the JS stack in use.
​https://bugs.webkit.org/show_bug.cgi?id=179936
<rdar://problem/35623998>

Reviewed by Saam Barati.

This issue was uncovered when we enabled --useDollarVM=true on the JSC tests.
See ​https://bugs.webkit.org/show_bug.cgi?id=179684.

Basically, in the case of the failing test we observed, op_tail_call_forward_arguments
was allocating stack space to stash arguments (to be forwarded) and new frame
info. The location of this new stash space happens to lie beyond the top of frame
of the tail call caller frame. After stashing the arguments, the code proceeded
to load the callee codeBlock. This triggered an allocation, which in turn,
triggered stack sanitization. The CLoop stack sanitizer was relying on
frame->topOfFrame() to tell it where the top of the used stack is. In this case,
that turned out to be inadequate. As a result, part of the stashed data was
zeroed out, and subsequently led to a crash.

This bug does not affect JIT builds (i.e. the ASM LLint) for 2 reasons:

1. JIT builds do stack sanitization in the LLInt code itself (different from the CLoop implementation), and the sanitizer there is aware of the true top of stack value (i.e. the stack pointer).
2. JIT builds don't use a parallel stack like the CLoop. The presence of the parallel stack is one condition necessary for reproducing this issue.

The fix is to make the CLoop record the stack pointer in CLoopStack::m_currentStackPointer
every time before it calls out to native C++ code. This also brings the CLoop's
behavior closer to hardware behavior where we can know where the stack pointer
is after calling from JS back into native C++ code, which makes it easier to
reason about correctness.

Also simplified the various stack boundary calculations (removed the +1 and -1
adjustments). The CLoopStack bounds are now:

reservationTop(): the lowest reserved address that can be within stack bounds.
m_commitTop: the lowest address within stack bounds that has been committed.
lowAddress() aka m_end: the lowest stack address that JS code can use.
m_lastStackPointer: cache of the last m_currentStackPointer value.
m_currentStackPointer: the CLoopStack stack pointer value when calling from JS into C++ code.
highAddress(): the highest address just beyond the bounds of the stack.

Also deleted some unneeded code.

[Web Animations] Allow getComputedStyle() to return animated values for accelerated animations
​https://bugs.webkit.org/show_bug.cgi?id=179975
<rdar://problem/35676811>

Reviewed by Dean Jackson.

Source/WebCore:

In case we're running an accelerated animation, we are not blending RenderStyles as the animation
progresses and thus we need to hook into computeRenderStyleForProperty() to query the DocumentTimeline
for the animated style of running accelerated animations where we blend styles manually for the
animation's current time.

Test: http/wpt/wk-web-animations/interfaces/keyframe-effect-getComputedStyle.html

• animation/DocumentTimeline.cpp:

(WebCore::DocumentTimeline::animatedStyleForRenderer): Iterate through all running accelerated animations
for the element to which the provided renderer is attached and ask for their animated styles.

• animation/DocumentTimeline.h:
• animation/KeyframeEffect.cpp:

(WebCore::KeyframeEffect::getAnimatedStyle): Manually blend all animated properties and populate the provided
RenderStyle with their values, creating the RenderStyle if needed.

• animation/KeyframeEffect.h:
• css/CSSComputedStyleDeclaration.cpp:

(WebCore::computeRenderStyleForProperty): Query the DocumentTimeline for accelerated animated properties in
case such animations are running, otherwise let the CSS animation controller report the animated values.

LayoutTests:

Add a new test that checks that the computed style of accelerated animation returns the animated value.
This test would fail for the accelerated case prior to this patch.

• http/wpt/wk-web-animations/interfaces/keyframe-effect-getComputedStyle-expected.txt: Added.

[CoordGraphics] CoordinatedGraphicsLayer::updateContentBuffers() should always assume a non-null CoordinatedBuffer
​https://bugs.webkit.org/show_bug.cgi?id=179977

Reviewed by Carlos Garcia Campos.

Source/WebCore:

CoordinatedGraphicsLayer::updateContentBuffers() retrieves a RefPtr<CoordinatedBuffer>
from the CompositingCoordinator. This pointer should never be null since if no
existing UpdateAtlas can provide the necessary memory area, a fresh UpdateAtlas is
created and its buffer returned. This can't fail in theory since the tiles that are
being updated are smaller than the UpdateAtlas area.

The CoordinatedGraphicsLayerClient::getCoordinatedBuffer() method is updated to
always return a Ref<CoordinatedBuffer> value. Code in updateContentBuffers() is
updated to remove a null-check on what is now the Ref<CoordinatedBuffer> value.

No new tests -- no change in functionality.

• platform/graphics/texmap/coordinated/CoordinatedGraphicsLayer.cpp:

(WebCore::CoordinatedGraphicsLayer::updateContentBuffers):

• platform/graphics/texmap/coordinated/CoordinatedGraphicsLayer.h:

Source/WebKit:

Make CompositingCoordinator::getCoordinatedBuffer() return a Ref<CoordinatedBuffer>
value. In case an UpdateAtlas with enough free area is found, its CoordinatedBuffer
is dereferenced into the return value. In case a new UpdateAtlas is created, the
returned CoordinatedBuffer pointer is asserted to be non-null and dereferenced.

The retrieved CoordinatedBuffer pointer on a newly-created UpdateAtlas should never
be null since the tiles are smaller in size than the UpdateAtlas area. The assert
is done in release configurations as well since the code in CoordinatedGraphicsLayer
assumes the returned pointer will be non-null, so it's just a matter of where to
crash first in case somehow a null value is returned.

[CoordGraphics] UpdateAtlas constructor should receive an IntSize, not a dimension value
​https://bugs.webkit.org/show_bug.cgi?id=179976

Reviewed by Carlos Garcia Campos.

Have the UpdateAtlas constructor receive an IntSize object that specifies
the desired size for the CoordinatedBuffer. Passing in a dimension doesn't
really make sense since this value isn't dynamically configurable, and
the only value that is passed in is already a power-of-two.

[JSC] Make empty key as deleted mark in HashMapBucket and drop m_deleted field
​https://bugs.webkit.org/show_bug.cgi?id=179923

Reviewed by Darin Adler.

We do not set empty as a key in HashMapBucket since JSMap / JSSet can expose it to users.
So we can use it as a marker of deleted bucket.

This patch uses empty key as a deleted flag, and drop m_deleted field of HashMapBucket.
It shrinks the size of HashMapBucket much.

Tools:

Always set --useDollarVM=true for jsc runs of benchmarks. This is needed because
some microbenchmarks relies on createBuiltin().

Also set --useDollarVM=true for runExceptionFuzz and runExecutableAllocationFuzz.

Source/WebCore:
[Web Animations] Perform accelerated animations when possible
​https://bugs.webkit.org/show_bug.cgi?id=179973
<rdar://problem/34953922>

Reviewed by Dean Jackson.

When we're entering and leaving the active duration of an animation effect, we now check
whether the animation can be accelerated, using the existing CSSPropertyAnimation::animationOfPropertyIsAccelerated()
utility, and start and stop animations using the startAnimation() and animationFinished() functions on RenderBoxModelObject.

This patch is only a first step towards full support for accelerated animations,
there are two known issues at the moment. Because we're not blending the styles to perform
the animation, getComputedStyle() will not return the animated value (webkit.org/b/179974).
Additionally, if other animations happen to run later during the active state of an animation
that can run accelerated, we will not fall back to software-only animation for this
element and these animations will appear not to run (webkit.org/b/179975). These will be
addressed in follow-up patches.

• animation/DocumentTimeline.cpp:

(WebCore::DocumentTimeline::updateAnimations): Check in the map of pending accelerated animations
to see if any animation requires toggling their active state after their styles have been invalidated.
(WebCore::DocumentTimeline::animationAcceleratedRunningStateDidChange): New function to
let animations indicate that they need to have their accelerated backing animation toggled after
style invalidation has been completed.
(WebCore::DocumentTimeline::runningAnimationsForElementAreAllAccelerated): This function is used
in RenderLayerCompositor::requiresCompositingForAnimation() to identify whether an element requires
hardware compositing due to running accelerated animations. We check all running animations for the
provided element to see if they can all be running accelerated and return true in this situation only.

• animation/DocumentTimeline.h:
• animation/KeyframeEffect.cpp:

(WebCore::KeyframeEffect::applyAtLocalTime): Identify if we're crossing into or out of the active state
for an animation and check if it will be or has been running accelerated such that we can notify the
DocumentTimeline, through the associated animation, that the accelerated backing animation will need to
be toggled after style invalidation has been completed.
(WebCore::KeyframeEffect::shouldRunAccelerated): Check that all properties for this animation
effect can be accelerated according to CSSPropertyAnimation::animationOfPropertyIsAccelerated().
(WebCore::KeyframeEffect::startOrStopAccelerated): Start or stop the associated accelerated
animation through the associated element's RenderBoxModelObject renderer.

• animation/KeyframeEffect.h:
• animation/WebAnimation.cpp:

(WebCore::WebAnimation::acceleratedRunningStateDidChange): Called from AnimationEffect::applyAtLocalTime(),
we forward to the DocumentTimeline the information that the animation will cross an active state boundary while
allowing to be backed by hardware compositing.
(WebCore::WebAnimation::startOrStopAccelerated): Forward to the associated KeyframeEffect that accelerated
animation backing should be toggled.

• animation/WebAnimation.h:
• rendering/RenderLayerCompositor.cpp:

(WebCore::RenderLayerCompositor::requiresCompositingForAnimation const): Check via the renderer's element's
DocumentTimeline that all running animations for this particular element are accelerated to ensure that
the element will be hardware-composited.

Add a series of tests to check that we use hardware-compositing for animations when possible.
Specifically, we check that:

1. Specifying both accelerated and non-accelerated properties for a single animation does *not*

yield hardware compositing (left-and-opacity-animation-yields-no-compositing.html).

2. Specifying both accelerated and non-accelerated properties via multiple animations does *not*

yield hardware compositing (width-and-opacity-separate-animation-yields-no-compositing.html).

3. Specifying only accelerated properties *does* yield hardware compositing

(opacity-animation-yields-compositing.html).

4. Hardware-composited animations no longer enforce hardware compositing after their completion

(opacity-animation-no-longer-composited-upon-completion.html).
