[GTK][Threaded Compositor] ASSERTION FAILED: !!handle ^{!!m_nativeSurfaceHandle with several layout tests
​https://bugs.webkit.org/show_bug.cgi?id=160143}

Reviewed by Michael Catanzaro.

We have a message to set the native surface handle and another one for destroying it, the former is a normal
message while the latter is sync. This assertion happens if the web view is realized before the web process is
launched. This is the sequence:

1.- DrawingAreaProxyImpl sends SetNativeSurfaceHandleForCompositing message to the web process, since the
process hasn't been launched yet, the message is queued.
2.- Web process is launched and queued messages are now sent to the web process.
3.- The page is closed right after the web process is launched, and DrawingAreaProxyImpl sends
DestroyNativeSurfaceHandleForCompositing to the web process.
4.- The web process processes incoming messages, and DestroyNativeSurfaceHandleForCompositing is processed before
SetNativeSurfaceHandleForCompositing because it's sync.
5.- The web process processes SetNativeSurfaceHandleForCompositing message.

This is not only producing the assertion, it's also setting a handle for a X window already destroyed in the UI
process, so this could be producing the X errors we have seen in other tests. So, we need to make sure
SetNativeSurfaceHandleForCompositing and DestroyNativeSurfaceHandleForCompositing are handled in order by the
web process. We could make SetNativeSurfaceHandleForCompositing sync as well, but sync messages are just ignored
when sent before the web process has been launched (only normal messages are queued for obvious reasons). The
other option is sending the SetNativeSurfaceHandleForCompositing message with the
IPC::DispatchMessageEvenWhenWaitingForSyncReply flag. In this case the message is queued and dispatched on
process launch, but it's dispatched before other messages also queued without that flag, like
CreateWebPage. Since there's no WebPage the web process doesn't find a valid message receiver for it and
it's discarded. We need to ensure the DrawinArea object has been created before sending the
SetNativeSurfaceHandleForCompositing with the PC::DispatchMessageEvenWhenWaitingForSyncReply flag.

• UIProcess/DrawingAreaProxyImpl.cpp:

(WebKit::DrawingAreaProxyImpl::didUpdateBackingStoreState): If we have received the first update and there's a
SetNativeSurfaceHandleForCompositing message pending, send it.
(WebKit::DrawingAreaProxyImpl::setNativeSurfaceHandleForCompositing): Do not send the message before the first
update is received.
(WebKit::DrawingAreaProxyImpl::destroyNativeSurfaceHandleForCompositing): If there was a
SetNativeSurfaceHandleForCompositing message pending, just ignore this destroy since the web process never
received the handle.

[Fetch API] Request should be created with any HeadersInit data
​https://bugs.webkit.org/show_bug.cgi?id=159672

Patch by Youenn Fablet <​youenn@apple.com> on 2016-07-24

LayoutTests/imported/w3c:

• imported/w3c/web-platform-tests/fetch/api/credentials/authentication-basic-expected.txt: Test was previously

failing due to lack of support for HeadersInit data in Request constructor.

• platform/mac-wk1/imported/w3c/web-platform-tests/fetch/api/credentials/authentication-basic-expected.txt: Removed.

Source/WebCore:

Made Request use JSBuiltinConstructor.
This allows initializing newly created Request with a JS built-in function, initializeFetchRequest.
initializeFetchRequest can call @fillFetchHeaders internal built-in to handle any HeadersInit data.
Future effort should be made to migrate more initialization code in initializeFetchRequest.

Made window and worker fetch function as a JS built-in.
This becomes more handy as these new functions can construct the Request object.
They can then call a single private function that takes a Request object as input.
Updated DOMWindowFetch and WorkerGlobalScopeFetch code accordingly.

To enable this, the binding generator is updated to support runtime-enabled JS built-in functions and
private functions atttached to global objects.

Covered by existing and modified tests.
Binding generator test covered by updated binding tests.

B3 should support multiple entrypoints
​https://bugs.webkit.org/show_bug.cgi?id=159391

Reviewed by Saam Barati.
Source/JavaScriptCore:

This teaches B3 how to compile procedures with multiple entrypoints in the best way ever.

Multiple entrypoints are useful. We could use them to reduce the cost of compiling OSR
entrypoints. We could use them to implement better try/catch.

Multiple entrypoints are hard to support. All of the code that assumed that the root block
is the entrypoint would have to be changed. Transformations like moveConstants() would have
to do crazy things if the existence of multiple entrypoints prevented it from finding a
single common dominator.

Therefore, we want to add multiple entrypoints without actually teaching the compiler that
there is such a thing. That's sort of what this change does.

This adds a new opcode to both B3 and Air called EntrySwitch. It's a terminal that takes
one or more successors and no value children. The number of successors must match
Procedure::numEntrypoints(), which could be arbitrarily large. The semantics of EntrySwitch
are:

• Each of the entrypoints sets a hidden Entry variable to that entrypoint's index and jumps to the procedure's root block.

• An EntrySwitch is a switch statement over this hidden Entry variable.

The way that we actually implement this is that Air has a very late phase - after all
register and stack layout - that clones all code where the Entry variable is live; i.e all
code in the closure over predecessors of all blocks that do EntrySwitch.

Usually, you would use this by creating an EntrySwitch in the root block, but you don't
have to do that. Just remember that the code before EntrySwitch gets cloned for each
entrypoint. We allow cloning of an arbitrarily large amount of code because restricting it,
and so restricing the placement of EntrySwitches, would be unelegant. It would be hard to
preserve this invariant. For example we wouldn't be able to lower any value before an
EntrySwitch to a control flow diamond.

This patch gives us an easy-to-use way to use B3 to compile code with multiple entrypoints.
Inside the compiler, only code that runs very late in Air has to know about this feature.
We get the best of both worlds!

Also, I finally got rid of the requirement that you explicitly cast BasicBlock* to
FrequentedBlock. I can no longer remember why I thought that was a good idea. Removing it
doesn't cause any problems and it makes code easier to write.

[B3] Fusing immediates into test instructions should work again
​https://bugs.webkit.org/show_bug.cgi?id=160073

Reviewed by Sam Weinig.

When we introduced BitImm, we forgot to change the Branch(BitAnd(value, constant))
fusion. This emits test instructions, so it should use BitImm for the constant. But it
was still using Imm! This meant that isValidForm() always returned false.

This fixes the code path to use BitImm, and turns off our use of BitImm64 on x86 since
it provides no benefit on x86 and has some risk (the code appears to play fast and loose
with the scratch register).

This is not an obvious progression on anything, so I added comprehensive tests to
testb3, which check that we selected the optimal instruction in a variety of situations.
We should add more tests like this!

[Coordinated Graphics] ASSERTION FAILED: !m_flushingLayers in fast/repaint/animation-after-layer-scroll.html
​https://bugs.webkit.org/show_bug.cgi?id=160142

Patch by Carlos Garcia Campos <​cgarcia@igalia.com> on 2016-07-24
Reviewed by Michael Catanzaro.

This only happens in layout tests, because it happens when RenderLayerCompositor::layerTreeAsText() is
called. The thing is that CoordinatedGraphicsLayer::flushCompositingState() calls notifyFlushRequired() that
checks if the coordinator is flusing layers and if not it calls RenderLayerCompositor::notifyFlushRequired() and
returns early. This normally works because the coodinator is the one starting the layer flush, so that when
RenderLayerCompositor::flushPendingLayerChanges() is called the coordinator is always flusing layers. But
RenderLayerCompositor::layerTreeAsText() calls RenderLayerCompositor::flushPendingLayerChanges() directly, so at
that moment the coordinator is not flusing layers, what causes that
CoordinatedGraphicsLayer::flushCompositingState() ends up calling RenderLayerCompositor::notifyFlushRequired()
that schedules a new flush while flusing layers causing the
assertion. CoordinatedGraphicsLayer::flushCompositingState() is always called from
CompositingCoordinator::flushPendingLayerChanges() or RenderLayerCompositor::flushPendingLayerChanges() so we
never need to call RenderLayerCompositor::notifyFlushRequired() from there.

[Coordinated Graphics] Lots of flaky tests
​https://bugs.webkit.org/show_bug.cgi?id=160118

Patch by Carlos Garcia Campos <​cgarcia@igalia.com> on 2016-07-23
Reviewed by Michael Catanzaro.

Source/WebCore:

Since the GTK+ ported to threaded compositor (coordinated graphics) there are a lot of flaky tests in the
bots. In manu of the cases the diff shows a different size in the FrameView layer.

This happens for tests run in the same WTR after fast/fixed-layout/fixed-layout.html. This is what happens:

1.- Test fast/fixed-layout/fixed-layout.html runs and sets fixed layout to true and fixed layout size to 400x400
2.- When it finishes TestController::resetStateToConsistentValues() is called.
3.- Blank URL is loaded after state has been updated
4.- Then Reset message is handled in the web process and Internals::resetToConsistentState() resets the fixed

layout state and size.

5.- onresize happens and the handler set in fast/fixed-layout/fixed-layout.html is invoked setting the fixed

layout to true and size to 400x400 again.

6.- about_blank is then loaded with the fixed layout enabled, as well as other tests after this one.

In addition to this, coordinated graphics uses a fixedVisibleContentRect in ScrollView that is never reset.

• platform/ScrollView.cpp:

(WebCore::ScrollView::unscaledVisibleContentSizeIncludingObscuredArea): Only use m_fixedVisibleContentRect when
fixed layout is enabled.
(WebCore::ScrollView::unscaledUnobscuredVisibleContentSize): Ditto.
(WebCore::ScrollView::visibleContentRectInternal): Ditto.

• testing/Internals.cpp:

(WebCore::Internals::resetToConsistentState): Reset also the m_fixedVisibleContentRect.

LayoutTests:

• fast/fixed-layout/fixed-layout.html: Remove the onresize handler when the test finishes to ensure it can't be

called later affecting other tests.

When evaluating performKeyboardInteractions, we were sending all
NSEvents synchronously, but because WebPageProxy was doing its
own queueing and asynchronous processing of those key events, we
would receive and respond to the next Automation command before

Removing IndexedDatabases that have stored blobs doesn't remove the blob files.
​https://bugs.webkit.org/show_bug.cgi?id=160089

Reviewed by Darin Adler.

Source/WebCore:

Tested by API test IndexedDB.StoreBlobThenDelete.

Blob filenames exist in the IDB directory with the name "[0-9]+.blob".

That is, one or more digits, followed by ".blob".

So when we delete an IndexedDB.sqlite3 and related files, we should delete those blob files as well.

Teach MarkedSpace how to allocate auxiliary storage
​https://bugs.webkit.org/show_bug.cgi?id=160053

Reviewed by Sam Weinig.

Previously, we had two kinds of subspaces in MarkedSpace: destructor and non-destructor. This
was described using "bool needsDestruction" that would get passed around. We'd iterate over
these spaces using duplicated code - one loop for destructors and one for non-destructors, or
a single loop that does one thing for destructors and one for non-destructors.

But now we want a third subspace: non-destructor non-JSCell, aka Auxiliary.

So, this changes all of the reflection and iteration over subspaces to use functors, so that
the looping is written once and reused. Most places don't even have to know that there is a
third subspace; they just know that they must do things for each subspace, for each
allocator, or for each block - and the functor magic handles it for you.

To make this somewhat nice, this change also fixes how we describe subspaces. Instead of a
bool, we now have AllocatorAttributes, which is a struct. If we ever add more subspaces, we
can add fields to AllocatorAttributes to describe how those subspaces differ. For now it just
contains two properties: a DestructionMode and a HeapCell::Kind. The DesctructionMode
replaces bool needsDestruction. I deliberately used a non-class enum to avoid tautologies.
DestructionMode has two members: NeedsDestruction and DoesNotNeedDestruction. I almost went
with DestructionMode::Needed and DestructionMode::NotNeeded, but I felt like that involves
more typing and doesn't actually avoid any kind of namespace issues.

This is intended to have no behavior change other than the addition of a totally unused
space, which should always be empty. So hopefully it doesn't cost anything.

run-builtins-generator-tests should be able to test WebCore builtins wrapper with more than one file
​https://bugs.webkit.org/show_bug.cgi?id=159921

Patch by Youenn Fablet <​youenn@apple.com> on 2016-07-22
Reviewed by Brian Burg.

Source/JavaScriptCore:

Updated built-in generator to generate only wrapper files when passed the --wrappers-only option.
When this option is used, wrapper files are generated but no individual file is generated.
When this option is not used, individual files are generated but not wrapper file is generated.
This allows the builtin generator test runner to generate a single WebCore-Wrappers.h-result generated for all
WebCore test files, like used for real in WebCore.
Previously wrapper code was generated individually for each WebCore test file.

Added new built-in test file to cover the case of concatenating several guards in generated WebCore wrapper files.

• Scripts/generate-js-builtins.py:

(concatenated_output_filename): Compute a decent name for wrapper files in case of test mode.
(generate_bindings_for_builtins_files): When --wrappers-only is activated, this generates only the wrapper files, not the individual files.

• Scripts/tests/builtins/WebCore-AnotherGuardedInternalBuiltin-Separate.js: Added.
• Scripts/tests/builtins/expected/WebCore-AnotherGuardedInternalBuiltin-Separate.js-result: Added.
• Scripts/tests/builtins/expected/WebCore-ArbitraryConditionalGuard-Separate.js-result: Removed wrapper code.

• Scripts/tests/builtins/expected/WebCoreJSBuiltins.h-result: Added, contains wrapper code for all WebCore valid test cases.

Source/WebCore:

Covered by existing and added built-ins tests.

Updating built system according ---wrappers-only new meaning.
builtin generator is now called for each individual built-in file plus once for WebCore wrapper files.
WebCore wrapper files allow handling things like conditionally guarded features.
They also remove the need to use built-ins macros outside generated code.

• CMakeLists.txt:
• DerivedSources.make:

Tools:

Updated builtin generator test runner to generate WebCore wrapper files based on all WebCore valid separate files.

• Scripts/webkitpy/codegen/main.py:

(BuiltinsGeneratorTests.generate_from_js_builtins): Passing a list of builtin files to the script.
(BuiltinsGeneratorTests):

Move parsing of accentunder and accent attributes from renderer to element classes
​https://bugs.webkit.org/show_bug.cgi?id=159625

Patch by Frederic Wang <​fwang@igalia.com> on 2016-07-21
Reviewed by Brent Fulgham.

We introduce a new MathMLUnderOverElement that is used for elements munder, mover and
munderover in order to create RenderMathMLUnderOver and parse and expose the values of the
accent and accentunder attributes. This is one more step toward moving MathML attribute
parsing to the DOM (bug 156536). We also do minor clean-up for this and previous renderer
classes that no longer do attribute parsing: the MathMLNames namespace is no longer necessary
and constructors can take a more accurate element type.

callOperation(.) variants in the DFG that explicitly take a tag/payload register should take a JSValueRegs instead
​https://bugs.webkit.org/show_bug.cgi?id=160007

Reviewed by Filip Pizlo.

This patch is the first step in my plan to remove all callOperation(.) variants
in the various JITs and to unify them using a couple template variations.
The steps are as follows:

1. Replace all explicit tag/payload pairs with JSValueRegs in the DFG
2. Replace all explicit tag/payload pairs with JSValueRegs in the baseline
3. remove callOperation(.) variants and teach setupArgumentsWithExecState about JSValueRegs.

REGRESSION (r202927): The internal size of the ImageBuffer is scaled twice by the context scaleFactor
​https://bugs.webkit.org/show_bug.cgi?id=159981
<rdar://problem/27429465>

Reviewed by Myles Maxfield.

Source/WebCore:

The change to propagate color spaces through ImageBuffers created an
alternate version of createCompatibleBuffer. This version accidentally
attempted to take the display resolution (i.e. hidpi) into account
when creating the buffer, which meant it was being applied twice.

The fix is simply to remove that logic. The caller of the method
will take the resolution into account, the same way they did
with the old createCompatibleBuffer method.

Test: fast/hidpi/pdf-image-scaled.html

• platform/graphics/cg/ImageBufferCG.cpp:

a resolution - just use the value of 1.0.

[iOS] Apps using WKWebView will crash if they set the scroll view's delegate and don't nil it out later
​https://bugs.webkit.org/show_bug.cgi?id=159980
rdar://problem/27450825

Patch by Chelsea Pugh <​cpugh@apple.com> on 2016-07-21
Reviewed by Dan Bernstein.

Source/WebKit2:

The root cause of this crash is that we are not abiding the UIScrollView API that the scroll view
delegate property should be weak. If setters of this delegate do not know that, since the WKWebView
exposes the scroll view as a UIScrollView, they may forget to nil out the delegate they set and will
then crash.

Reviewed by Chris Fleizach.

Source/WebCore:

Actually we are exposing the correct information for heading objects. On macOS,
VoiceOver should handle the logic that picks the right information to speak.
On iOS, VoiceOver is speaking the static text child instead of the heading object.
So we should set the accessibilityLabel of the static text based on the parent's
alternate label.

op_add/ValueAdd should be an IC in all JIT tiers
​https://bugs.webkit.org/show_bug.cgi?id=159649

Reviewed by Benjamin Poulain.

Source/JavaScriptCore:

This patch makes Add an IC inside all JIT tiers. It does so in a
simple, but effective, way. We will try to generate an int+int add
that will repatch itself if its type checks fail. Sometimes though,
we have runtime type data saying that the add won't be int+int.
In those cases, we will just generate a full snippet that doesn't patch itself.
Other times, we may generate no inline code and defer to making a C call. A lot
of this patch is just refactoring ResultProfile into what we're now calling ArithProfile.
ArithProfile does everything ResultProfile used to do, and more. It records simple type
data about the LHS/RHS operands it sees. This allows us to determine if an op_add
has only seen int+int operands, etc. ArithProfile will also contain the ResultType
for the LHS/RHS that the parser feeds into op_add. ArithProfile now fits into 32-bits.
This means instead of having a side table like we did for ResultProfile, we just
inject the ArithProfile into the bytecode instruction stream. This makes asking
for ArithProfile faster; we no longer need to lock around this operation.

The size of an Add has gone down on average, but we can still do better.
We still generate a lot of code because we generate calls to the slow path.
I think we can make this better by moving the slow path to a shared thunk
system. This patch mostly lays the foundation for future improvements to Add,
and a framework to move all other arithmetic operations to be typed-based ICs.

Here is some data I took on the average op_add/ValueAdd size on various benchmarks:

| JetStream | Speedometer | Unity 3D |

------| -------------

Old | 189 bytes | 169 bytes | 192 bytes |

------| -------------

New | 148 bytes | 124 bytes | 143 bytes |

---------------------------------------------------

Making an arithmetic IC is now easy. The JITMathIC class will hold a snippet
generator as a member variable. To make a snippet an IC, you need to implement
a generateInline(.) method, which generates the inline IC. Then, you need to
generate the IC where you used to generate the snippet. When generating the
IC, we need to inform JITMathIC of various data like we do with StructureStubInfo.
We need to tell it about where the slow path starts, where the slow path call is, etc.
When generating a JITMathIC, it may tell you that it didn't generate any code inline.
This is a request to the user of JITMathIC to just generate a C call along the
fast path. JITMathIC may also have the snippet tell it to just generate the full
snippet instead of the int+int path along the fast path.

In subsequent patches, we can improve upon how we decide to generate int+int or
the full snippet. I tried to get clever by having double+double, double+int, int+double,
fast paths, but they didn't work out nearly as well as the int+int fast path. I ended up
generating a lot of code when I did this and ended up using more memory than just generating
the full snippet. There is probably some way we can be clever and generate specialized fast
paths that are more successful than what I tried implementing, but I think that's worth deferring
this to follow up patches once the JITMathIC foundation has landed.

This patch also fixes a bug inside the slow path lambdas in the DFG.
Before, it was not legal to emit an exception check inside them. Now,
it is. So it's now easy to define arbitrary late paths using the DFG
slow path lambda API.

Fix null handling of SVGAngle/SVGLength.valueAsString attribute

Fix null handling of SVGAngle/SVGLength.valueAsString attribute
to match the specification:

• ​https://www.w3.org/TR/SVG2/types.html#InterfaceSVGAngle
• ​https://www.w3.org/TR/SVG2/types.html#InterfaceSVGLength

In particular, this patch drops [TreatNullAs=EmptyString] IDL
extended attribute from this attribute. This is not supposed
to change behavior given that both "" and "null" are invalid
numbers and the specification says to throw a SYNTAX_ERR in
this case.

However, WebKit currently ignores assignments to "" instead
of throwing. As a result, assigning to null will now throw
instead of being ignored. The compatibility risk should be
low because both Firefox and Chrome throw when assigning
null.

I did not change the behavior when assigning to "" because
it is a bit out of scope for this patch and browsers to not
seem to agree:

• Firefox throws
• Chrome set value to "0"
• WebKit ignores the assignment

The specification seems to agree with Firefox as far as I
can tell given that "" is not a valid number as per:

Test platform/ios-simulator/ios/plugin/youtube-flash-plugin-iframe.html is flaky
​https://bugs.webkit.org/show_bug.cgi?id=160002

Reviewed by Alexey Proskuryakov.

The file platform/ios-simulator/ios/plugin/youtube-flash-plugin-iframe.html tests loading
plugin content from the main frame and from a subframe. Depending on timing the plugin
content loaded in the subframe may complete before plugin content loaded in the main frame.
We should test loading plugin content in a subframe after perform all main frame sub-tests
so as to ensure a well-defined sub-test order.

Add logic to ensure that an embedded YouTube flash video loaded in a subframe actually creates
a shadow DOM. Additionally, simplify the test logic by making use window.jsTestIsAsync/finishJSTest()
to mark the test as asynchronous and notify test completion instead of calling
window.testRunner.{waitUntilDone, notifyDone}(), remove the call to
testRunner.dumpAsText() (js-test-pre.js calls this for us), remove all of the DOM elements
used in the test to avoid noise in the expected results, and fix some style nits.

REGRESSION: Plugin replaced YouTube Flash videos always have the same width
​https://bugs.webkit.org/show_bug.cgi?id=159998
<rdar://problem/27462285>

Reviewed by Simon Fraser.

Source/WebCore:

Fixes an issue where the width of a plugin replaced YouTube video loaded via an HTML embed
element would always have the same width regardless of value of the width attribute.

For YouTube Flash videos the YouTube plugin replacement substitutes a shadow DOM subtree
for the default renderer of an HTML embed element. The root of this shadow DOM subtree
is an HTML div element. Currently we set inline styles on this <div> when it is instantiated.
In particular, we set inline display and position to "inline-block" and "relative", respectively,
and set an invalid height and width (we specify a font weight value instead of a CSS length value

• this causes an ASSERT_NOT_REACHED() assertion failure in StyleBuilderConverter::convertLengthSizing()

in a debug build). These styles never worked as intended and we ultimately created an inline
renderer (ignoring display "inline-block") that had auto width and height. Instead it is sufficient
to remove all these inline styles and create a RenderBlockFlow renderer for this <div> so that it
renders as a block, non-replaced element to achieve the intended illusion that the <embed> is a
single element.

• html/shadow/YouTubeEmbedShadowElement.cpp: Remove unused header HTMLEmbedElement.h and include

header RenderBlockFlow.h. Also update copyright in license block.
(WebCore::YouTubeEmbedShadowElement::YouTubeEmbedShadowElement): Remove inline styles as these

[iPhone] Playing a video on tudou.com plays only sound, no video
​https://bugs.webkit.org/show_bug.cgi?id=159967
<rdar://problem/26964090>

Reviewed by Jon Lee, Jeremy Jones, and Anders Carlsson.

Source/WebCore:

WebKit recently starting honoring the playsinline and webkit-playsinline
attribute on iPhones. However, because these attributes previously did
nothing, some sites (such as Todou) were setting them on their content
and expecting that they are not honored. In this specific case, the
video is absolutely positioned to be 1 pixel x 1 pixel.

Previously, with iOS 9, apps could set the allowsInlineMediaPlayback
property on their WKWebView, which would honor the webkit-playsinline
attribute. Safari on iPhones didn't do this.

In order to not break these existing apps, it's important that the
allowsInlineMediaPlayback preference still allows webkit-playsinline
videos to play inline in apps using WKWebView. However, in Safari, these
videos should play fullscreen. (Todou videos have webkit-playsinline
but not playsinline.)

Therefore, in Safari, videos with playsinline should be inline, but
videos with webkit-playsinline should be fullscreen. In apps using
WKWebViews, if the app sets allowsInlineMediaPlayback, then videos with
playsinline should be inline, and videos with webkit-playsinline should
also be inline. Videos on iPad and Mac should all be inline by default.

We can create some truth tables for the cases which need to be covered:

All apps on Mac / iPad:
Presence of playsinline | Presence of webkit-playsinline | Result
========================|================================|===========
Not present | Not present | Inline
Present | Not present | Inline
Not Present | Present | Inline
Present | Present | Inline

Safari on iPhone:
Presence of playsinline | Presence of webkit-playsinline | Result
========================|================================|===========
Not present | Not present | Fullscreen
Present | Not present | Inline
Not Present | Present | Fullscreen
Present | Present | Inline

App on iPhone which sets allowsInlineMediaPlayback:
Presence of playsinline | Presence of webkit-playsinline | Result
========================|================================|===========
Not present | Not present | Fullscreen
Present | Not present | Inline
Not Present | Present | Inline
Present | Present | Inline

The way to distinguish Safari from another app is to create an SPI
boolean preference which Safari can set. This is already how the
iPhone and iPad are differentiated using the requiresPlayInlineAttribute
which Safari sets but other apps don't. However, this preference is
no longer sufficient because Safari should now be discriminating
between the playsinline and webkit-playsinline attributes. Therefore,
this preference should be extended to two boolean preferences, which
this patch adds:

allowsInlineMediaPlaybackWithPlaysInlineAttribute
allowsInlineMediaPlaybackWithWebKitPlaysInlineAttribute

Safari on iPhone will set
allowsInlineMediaPlaybackWithWebKitPlaysInlineAttribute to true,
and allowsInlineMediaPlaybackWithWebKitPlaysInlineAttribute to
false. Other apps on iPhone will get their defaults values (because they
are SPI) which means they will both be true. On iPad and Mac, apps will
use the defaults values where both are false.

This patch adds support for these two preferences, but does not remove
the existing inlineMediaPlaybackRequiresPlaysInlineAttribute preference.
I will remove the exising preference as soon as I update Safari to migrate
off of it.

[GTK][Threaded Compositor] Overlay scrollbars shouldn't be a requirement of the threaded compositor
​https://bugs.webkit.org/show_bug.cgi?id=160020

Reviewed by Michael Catanzaro.

It has been a requirement only because we didn't really know why frame scrollbars were not rendered when using
the threaded compositor. The reason is that RenderView doesn't use layers for FrameView scrollbars by default,
unless using overlay scrollbars. When using the threaded compositor we really need layers for the FrameView
scrollbars even when not using overlay scrollbars.

[GTK][Threaded Compositor] WTR generates fully white images for pixel tests most of the time

WTR sends a force repaint message to the web process before taking a snapshot of the web view. With the threaded

[GTK] White page when loaded tab is visited until it's hovered when AC mode is always on
​https://bugs.webkit.org/show_bug.cgi?id=159512

Reviewed by Michael Catanzaro.

The redirected window is always mapped, but offscreen, to ensure that the web process can always render
there. When the web process renders something into the offscreen window, we receive a damage event in the UI
process and queue a redraw of the web view. However, when the web view is not mapped, even if we still receive
the damage events, the web view redraws are ignored until the view is mapped again (gtk_widget_queue_draw()
returns early when the widget is not visible). The redirected window updates its pixmap on demand when the
surface is requested, which happens when the web view draws its contents. So when the web view becames visible,
the redirected window creates a new pixmap and surface (the first time or if the web view was resized), that we
initialize to avoid artifacts when the web process hasn't render anything yet. That initialization is actually
overwriting anything rendered into the redirected window while the view was unmapped. That's why see white pages
the first time, and previous contents after a resize, and we don't see the actual contents until the web process
renders again and we reuse the existing pixmap. The white page didn't happen for tabs with accelerated content,
because in those cases the web process was rendering a new frame every 16ms, but instead there was a flickering
effect due to the current frame being overwritten when the view is mapped until the next frame.
So, instead of lazily create and initialize the redirected window pixmap and surface, we should always create
the new pixmap as soon as the window is created or resized (and not empty) This fixes the issues but also makes
resizing the window a bit smoother when AC mode is enabled.

[ES7] Introduce exponentiation expression
​https://bugs.webkit.org/show_bug.cgi?id=159969

Reviewed by Saam Barati.

This patch implements the exponentiation expression, e.g. x ** y.
The exponentiation expression is introduced in ECMA262 2016 and ECMA262 2016
is already released. So this is not the draft spec.

The exponentiation expression has 2 interesting points.

1. Right associative

To follow the Math expression, operator is right associative.
When we execute x ** y ** z, this is handled as x ** (y ** z), not (x ** y) ** z.
This patch introduces the right associativity to the binary operator and handles it
in the operator precedence parser in Parser.cpp.

2. LHS of the exponentiation expression is UpdateExpression

ExponentiationExpression[Yield]:

UnaryExpression?Yield
UpdateExpression?Yield ExponentiationExpression?Yield

As we can see, the left hand side of the ExponentiationExpression is UpdateExpression, not UnaryExpression.
It means that +x ** y becomes a syntax error. This is intentional. Without superscript in JS,
-x**y is confusing between -(x ** y) and (-x) ** y. So ECMA262 intentionally avoids UnaryExpression here.
If we need to use a negated value, we need to write parentheses explicitly e.g. (-x) ** y.
In this patch, we ensure that the left hand side is not an unary expression by checking an operator in
parseBinaryExpression. This works since ** has the highest operator precedence in the binary operators.

We introduce a new bytecode, op_pow. That simply works as similar as the other binary operators.
And it is converted to ArithPow in DFG and handled in DFG and FTL.
In this patch, we take the approach just introducing a new bytecode instead of calling Math.pow.
This is because we would like to execute ToNumber in the caller side, not in the callee (Math.pow) side.
And we don't want to compile into the following.

lhsNumber = to_number (lhs)
rhsNumber = to_number (rhs)
call Math.pow(lhsNumber, rhsNumber)

We ensure that this patch passes all the test262 tests related to the exponentiation expression.

The only sensitive part to the performance is the parser changes.
So we measured the code-load performance and it is neutral in my x64 Linux box (hanayamata).

Collected 30 samples per benchmark/VM, with 30 VM invocations per benchmark. Emitted a call to
gc() between sample measurements. Used 1 benchmark iteration per VM invocation for warm-up. Used
the jsc-specific preciseTime() function to get microsecond-level timing. Reporting benchmark
execution times with 95% confidence intervals in milliseconds.

Switching on symbols should be fast
​https://bugs.webkit.org/show_bug.cgi?id=158892

Reviewed by Keith Miller.
Source/JavaScriptCore:

This does two things: fixes some goofs in our lowering of symbol equality and adds a new phase
to B3 to infer switch statements from linear chains of branches.

This changes how we compile equality to Symbols to constant-fold the load of the Symbol's UID.
This is necessary for making switches on Symbols inferrable. This also gives us the ability to
efficiently compile strict equality comparisons of SymbolUse and UntypedUse.

This adds a new phase to B3, which finds chains of branches that test for (in)equality on the
same value and constants, and turns them into a Switch. This can turn O(n) code into
O(log n) code, or even O(1) code if the switch cases are dense.

This can make a big difference in JS. Say you write a switch in which the case statements are
variable resolutions. The bytecode generator cannot use a bytecode switch in this case, since
we're required to evaluate the resolutions in order. But in DFG IR, we will often turn those
variable resolutions into constants, since we do that for any immutable singleton. This means
that B3 will see a chain of Branches: the else case of one Branch will point to a basic block
that does nothing but Branch on equality on the same value as the first Branch.

The inference algorithm is quite simple. The basic building block is the ability to summarize
a block's switch behavior. For a block that ends in a switch, this is just the collection of
switch cases. For a block that ends in a branch, we recognize Branch(Equal(value, const)),
Branch(NotEqual(value, const)), and Branch(value). Each of these are summarized as if they
were one-case switches. We infer a new switch if both some block and its sole predecessor
can be described as switches on the same value, nothing shady is going on (like loops), and
the block in question does no work other than this switch. In that case, the block is killed
and its cases (which we get from the summary) are added to the predecessor's switch. This
algorithm runs to fixpoint.

FTL snippet generators should be able to request a different register for output and input
​https://bugs.webkit.org/show_bug.cgi?id=160010
rdar://problem/27439330

Reviewed by Saam Barati.

The BitOr and BitXor snippet generators have problems if the register for the right input is
the same as the register for the result. We could fix those generators, but I'm not convinced
that the other snippet generators don't have this bug. So, the approach that this patch takes
is to teach the FTL to request that B3 to use a different register for the result than for
any input to the snippet patchpoint.

Air already has the ability to let any instruction do an EarlyDef, which means exactly this.
But B3 did not expose this via ValueRep. This patch exposes this in ValueRep as
SomeEarlyRegister. That's most of the change.

This adds a testb3 test for SomeEarlyRegister and a regression test for this particular
problem. The regression test failed on trunk JSC before this.

Fix null handling of several Document attributes
​https://bugs.webkit.org/show_bug.cgi?id=159997

Reviewed by Ryosuke Niwa.

Source/WebCore:

Fix null handling of the following Document attributes: title, cookie
and domain.

In WebKit, they were all marked as [TreatNullAs=EmptyString], which
does not match the specification:

• ​https://html.spec.whatwg.org/multipage/dom.html#document

Details for each attribute:

• title: null is now treated as the string "null", thus setting the document title to "null". This matches Firefox and Chrome.
• cookie: adds a "null" cookie instead of being a no-op. This matches

both Firefox and Chrome.

• domain: Calls setDomain(String("null")) instead of

setDomain(String()). This throws an exception because "null"
is not a suffix of the effective domain name. The behavior
is the same in Firefox and Chrome. Previously, we were
already throwing an exception since setting the domain to
the empty string throws, as per the specification.

-_navigationGestureDidBegin already snapshots the visibleContentRect in _frozenVisibleContentRect,

Stop using valueToStringWithNullCheck() in JSCSSStyleDeclaration::putDelegate()
​https://bugs.webkit.org/show_bug.cgi?id=159982

Reviewed by Ryosuke Niwa.

Source/WebCore:

valueToStringWithNullCheck() treats null as the null String() which is
legacy / non standard behavior. The specification says we should treat
null as the empty string:

• ​https://drafts.csswg.org/cssom/#dom-cssstyledeclaration-camel-cased-attribute

Therefore, we should be using valueToStringTreatingNullAsEmptyString() instead.

In practice, there is no web-exposed behavior change because
MutableStyleProperties::setProperty() removes the property wether the
value is the null String or the empty String.

This behavior is correct since the specification says that we should
remove the property if the value is the empty string:

• ​https://drafts.csswg.org/cssom/#dom-cssstyledeclaration-setproperty (step 4)

[iPhone] Playing a video on tudou.com plays only sound, no video
​https://bugs.webkit.org/show_bug.cgi?id=159967
<rdar://problem/26964090>

Reviewed by Jon Lee.

Source/WebCore:

WebKit recently starting honoring the playsinline and webkit-playsinline
attribute on iPhones. However, because these attributes previously did
nothing, some sites (such as Todou) were setting them on their content
and expecting that they are not honored. In this specific case, the
video is absolutely positioned to be 1 pixel x 1 pixel.

Previously, with iOS 9, apps could set the allowsInlineMediaPlayback
property on their WKWebView, which would honor the webkit-playsinline
attribute. Safari on iPhones didn't do this.

In order to not break these existing apps, it's important that the
allowsInlineMediaPlayback preference still allows webkit-playsinline
videos to play inline in apps using WKWebView. However, in Safari, these
videos should play fullscreen. (Todou videos have webkit-playsinline
but not playsinline.)

Therefore, in Safari, videos with playsinline should be inline, but
videos with webkit-playsinline should be fullscreen. In apps using
WKWebViews, if the app sets allowsInlineMediaPlayback, then videos with
playsinline should be inline, and videos with webkit-playsinline should
also be inline. Videos on iPad and Mac should all be inline by default.

We can create some truth tables for the cases which need to be covered:

All apps on Mac / iPad:
Presence of playsinline | Presence of webkit-playsinline | Result
========================|================================|===========
Not present | Not present | Inline
Present | Not present | Inline
Not Present | Present | Inline
Present | Present | Inline

Safari on iPhone:
Presence of playsinline | Presence of webkit-playsinline | Result
========================|================================|===========
Not present | Not present | Fullscreen
Present | Not present | Inline
Not Present | Present | Fullscreen
Present | Present | Inline

App on iPhone which sets allowsInlineMediaPlayback:
Presence of playsinline | Presence of webkit-playsinline | Result
========================|================================|===========
Not present | Not present | Fullscreen
Present | Not present | Inline
Not Present | Present | Inline
Present | Present | Inline

The way to distinguish Safari from another app is to create an SPI
boolean preference which Safari can set. This is already how the
iPhone and iPad are differentiated using the requiresPlayInlineAttribute
which Safari sets but other apps don't. However, this preference is
no longer sufficient because Safari should now be discriminating
between the playsinline and webkit-playsinline attributes. Therefore,
this preference should be extended to two boolean preferences, which
this patch adds:

allowsInlineMediaPlaybackWithPlaysInlineAttribute
allowsInlineMediaPlaybackWithWebKitPlaysInlineAttribute

Safari on iPhone will set
allowsInlineMediaPlaybackWithWebKitPlaysInlineAttribute to true,
and allowsInlineMediaPlaybackWithWebKitPlaysInlineAttribute to
false. Other apps on iPhone will get their defaults values (because they
are SPI) which means they will both be true. On iPad and Mac, apps will
use the defaults values where both are false.

This patch adds support for these two preferences, but does not remove
the existing inlineMediaPlaybackRequiresPlaysInlineAttribute preference.
I will remove the exising preference as soon as I update Safari to migrate
off of it.

Get rid of custom bindings code for XMLHttpRequest.open()
​https://bugs.webkit.org/show_bug.cgi?id=159984

Reviewed by Ryosuke Niwa.

Get rid of custom bindings code for XMLHttpRequest.open() as the
bindings generator is able to generate it.

Relevant specification:

• ​https://xhr.spec.whatwg.org/#xmlhttprequest

The issue is that legacy content prevents treating the 'async' argument
being undefined identical from it being omitted. However, this can be
achieved by using overloading in IDL, like in the specification.

PostResolutionCallbackDisabler can resume pending requests while a ResourceLoadSuspender is alive
​https://bugs.webkit.org/show_bug.cgi?id=159962
<rdar://problem/21439264>

Reviewed by David Kilzer.

PostResolutionCallbackDisabler can resume pending requests while a ResourceLoadSuspender
is alive. We have both PostResolutionCallbackDisabler and ResourceLoadSuspender that
call LoaderStrategy::suspendPendingRequests() / LoaderStrategy::resumePendingRequests().
However, PostResolutionCallbackDisabler and ResourceLoadSuspender are not aware of each
other. It is therefore possible for a PostResolutionCallbackDisabler object to get
destroyed, causing LoaderStrategy::resumePendingRequests() to be called while a
ResourceLoadSuspender object is alive.

This leads to hard to investigate crashes where we end up re-entering WebKit and killing
the style resolver.

This patch drops ResourceLoadSuspender and uses PostResolutionCallbackDisabler instead.
There was only one user of ResourceLoadSuspender and PostResolutionCallbackDisabler
is better because it manages a resolutionNestingDepth counter internally to make sure
it only calls LoaderStrategy::resumePendingRequests() once all
PostResolutionCallbackDisabler instances are destroyed.

No new tests, there is no easy way to reproduce the crashes.
