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.

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.

[iOS] Apps using WKWebView will crash if they set the scroll view's delegate and don't nil it out later

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

then crash.

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
https://bugs.webkit.org/show_bug.cgi?id=160025

Reviewed by Ryosuke Niwa.

Source/WebCore:

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

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: svg/dom/valueAsString-null.html

Reviewed by Alexey Proskuryakov.

The file platform/ios-simulator/ios/plugin/youtube-flash-plugin-iframe.html tests loading

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.

[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] 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.

  1. 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.

[GTK] Avoid the redirected window resize when the view is realized in AC mode

Reviewed by Michael Catanzaro.

We are always creating the redirected window at 1x1 and then resizing it if we are in AC mode. When the view is
realized and AC mode is already enabled, which happens for example when AC mode is forced, or when the threaded

XWindow at the right size.

RedirectedXCompositeWindow already knows it.
(webkitWebViewBaseRealize): Pass the WebPageProxy and an initial size to the RedirectedXCompositeWindow

GdkWindow.

When the web view is unrealized, we send a sync message to the web process to destroy the native surface handle
for compositing, and then we actually destroy the redirected window. But if the page is closed explicitly before
the web view is unrealized, the drawing area proxy is destroyed so that when the web view is unrealized we can't
notify the web process that keeps trying to render to a now deleted window handle. That produces a BadDrawable

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

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:

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.

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:

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:

I added test coverage to make sure we behave according to specification.
This test is passing in Firefox, Chrome and in WebKit (before and after
my change).

[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.

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.

The default testing mode should not involve disabling the FTL JIT
https://bugs.webkit.org/show_bug.cgi?id=159929

Rubber stamped by Mark Lam and Saam Barati.

Source/JavaScriptCore:

Use the new powers to make some tests run only in the default configuration (i.e. FTL,
concurrent JIT).

  • tests/mozilla/mozilla-tests.yaml:

Tools:

It used to be the case that most actively maintained ports did not have the FTL JIT enabled.
Heck, for most of the FTL's initial development, it wasn't enabled anywhere. So, testing the
FTL was not the default. You had to enable it with an option.

For some reason we have kept this arrangement even though the FTL JIT is now the default on
all of the major ports. This has become a serious pain. For example, it's useful to be able
to say that a test should only run in the default config that is representative of what a
normal user would see if they ran JSC. Clearly, this would be a config that does not
explicitly disable the FTL JIT on the command line. However, if you try to specify this then
your test won't run at all if the --ftl-jit option is not passed. That's dangerous!

So, this change gets rid of all of this logic. I think it's better to get rid of it then to
try to fix it, because:

  • I don't know what the fix would look like. Presumably it would ensure that ports that don't have the FTL enabled never run any tests that explicitly disable the FTL, since that doesn't do anything. The code is not really structured to allow this.


  • It benefits a minority of clients. Three build bots run tests in a config that has the FTL disabled in testing. On the other hand there are already build bots that do FTL tests despite having the FTL disabled by virtue of being a 32-bit platform. So, maybe rather than preserving this broken feature, we should create something that (a) acknowledges the fact that the FTL is the default on those platforms that support it and (b) avoids running no-ftl tests on precisely those platforms that don't have FTL.


  • To the extent that some bots benefited from disabling FTL tests, they were doing it by relying on a feature that was never meant to stick around. The FTL JIT is meant to be the default configuration. Disabling the FTL JIT is the non-default. So, we shouldn't be pretending that the FTL JIT is not the default just because some bots used that as an optimization.


This change allows me to speed up some debug tests and paint some bots green.

autocapitalize attribute should not use [TreatNullAs=LegacyNullString]
https://bugs.webkit.org/show_bug.cgi?id=159934

Reviewed by Benjamin Poulain.

Source/WebCore:

autocapitalize attribute should not use [TreatNullAs=LegacyNullString]. This is
non-standard and we want to drop support for it from the bindings generator.

Instead, use [TreatNullAs=EmptyString] in order to maintain existing behavior
given that both a missing/empty attribute result in using the default
autocapitalization mode and that autocapitalize returns the empty string by
default.

Reviewed by Simon Fraser.

There is an iOS bug (<rdar://problem/27416744>) that is causing us
to not always get a color space on CGContextRefs. Investigation of this
exposed some optimizations we can take when we are creating ImageBuffers.
In particular, if we have a bitmap context or an IOSurfaceContext we
can simply copy their color space using API. Otherwise we stick with
the existing CGContextCopyDeviceColorSpace.

Lastly, if for some reason we are unable to copy the device color space,
we should fall back to sRGB.

REGRESSION (r203348-r203368): ASSERTION FAILED: from.isCell() && from.asCell()->JSCell::inherits(std::remove_pointer<To>::type::info())
https://bugs.webkit.org/show_bug.cgi?id=159930

Reviewed by Geoffrey Garen.

The problem is that the 32-bit DFG can flush the scope register as an unboxed cell, but the
Register::scope() method was causing us to assert that it's a JSValue with proper cell
boxing. We could have forced the DFG to flush it as a boxed JSValue, but I don't think that
would have made anything better. This fixes the issue by teaching Register::scope() that it
might see unboxed cells.

Reviewed by Simon Fraser.

Source/WebCore:

This patch fixes the case when

  • 2 disjoint subtrees are dirty
  • RenderView is also dirty.

and we end up not laying out one of the 2 subtrees.

In FrameView::scheduleRelayoutOfSubtree, we assume that when the RenderView is dirty
we already have a pending full layout which means that any previous subtree layouts have already been
converted to full layouts.
However this assumption is incorrect. RenderView can get dirty without checking if there's
already a pending subtree layout.
One option to solve this problem would be to override RenderObject::setNeedsLayout in RenderView
so that when the RenderView gets dirty, we could also convert any pending subtree layout to full layout.
However RenderObject::setNeedsLayout is a hot function and making it virtual would impact performance.
The other option is to always normalize subtree layouts in FrameView::scheduleRelayoutOfSubtree().
This patch implements the second option.

B3 methods that mutate the successors array should take FrequentedBlock by value
https://bugs.webkit.org/show_bug.cgi?id=159935

Reviewed by Michael Saboff.

This bug was found by ASan testing. setSuccessors() takes a const FrequentedBlock&, and the
caller that caused the ASan crash was doing:

block->setSuccessors(block->notTaken())

So, inside setSuccessors(), after we resize() the successors array, the const
FrequentedBlock& points to nonsense.

The fix is to pass FrequentedBlock by value in all of these kinds of methods.

No new tests, but ASan testing catches this instantly for anything that triggers CFG
simplification in B3. So like half of our tests.

RenderView::repaintRootContents() had a long-standing bug in WebView when the
view is scrolled. repaint() uses visualOverflowRect() but, for the
RenderView, the visualOverflowRect() is the initial containing block
which is anchored at 0,0. When the view is scrolled it's clipped out and
calls to repaintRootContents() have no effect.

Change repaintRootContents() to use layoutOverflowRect(). ScrollView::repaintContentRectangle()
will clip it to the view if necessary.

Implement table-based switches in B3/Air
https://bugs.webkit.org/show_bug.cgi?id=151141

Reviewed by Benjamin Poulain.
Source/JavaScriptCore:

If a switch statement gets large, it's better to express it as an indirect jump rather than
using a binary switch (divide-and-conquer tree of comparisons leading to O(log n) branches to
get to the switch case). When dealing with integer switches, FTL will already use the B3
Switch and expect this to get lowered as efficiently as possible; it's a bug that B3 will
always use a binary switch rather than indirect jumps. When dealing with switches over some
more sophisticated types, we'd want FTL to build an indirect jump table itself and use
something like a hashtable to feed it. In that case, there will be no B3 Switch; we'll want
some way for the FTL to directly express an indirection jump when emitting B3.

This implies that we want B3 to have the ability to lower Switch to indirect jumps and to
expose those indirect jumps in IR so that the FTL could do its own indirect jumps for
switches over more complicated things like strings. But indirect jumps are tough to express
in IR. For example, the LLVM approach ("indirectbr" and "blockaddress", see
http://blog.llvm.org/2010/01/address-of-label-and-indirect-branches.html) means that some
control flow edges cannot be split. Indirectbr takes an address as input and jumps to it, and
blockaddress lets you build jump tables out of basic block addresses. This means that the
compiler can never change any successor of an indirectbr, since the client will have already
arranged for that indirectbr to jump to exactly those successors. We don't want such
restrictions in B3, since B3 relies on being able to break critical edges for SSA conversion.
Also, indirectbr is not cloneable, which would break any hope of doing specialization-based
transformations like we want to do for multiple entrypoints (bug 159391). The goal of this
change is to let clients do indirect jumps without placing any restrictions on IR.

The trick is to allow Patchpoints to be used as block terminals. Patchpoints already allow
clients of B3 to emit whatever code they like. Patchpoints are friendly to B3's other
transformations because the client of the patchpoint has to play along with whatever
decisions B3 had made around the patchpoint: what registers got used, what the control flow
looks like, etc. Patchpoints can even be cloned by B3, and the client has to accommodate this
in their patchpoint generator. It turns out that using Patchpoints as terminals is quite
natural. We accomplish this by moving the successor edges out of ControlValue and into
BasicBlock, and removing ControlValue entirely. This way, any Value subclass can be a
terminal. It was already true that a Value is a terminal if value->effects().terminal, which
works great with Patchpoints since they control their effects via PatchpointValue::effects.
You can make your Patchpoint into a terminal by placing it at the end of a block and doing:

patchpoint->effects.terminal = true;

A Patchpoints in terminal position gets access to additional API in StackmapGenerationParams.
The generator can get a Box<Label> for each successor to its owning block. For example, to
implement a jump-table-based switch, you would make your patchpoint take the table index as
its sole input. Inside the generator, you allocate the jump table and emit a BaseIndex jump
that uses the jump table pointer (which will be a constant known to the generator since it
just allocated it) as the base and the patchpoint input as an index. The jump table can be
populated by MacroAssemblerCodePtr's computed by installing a link task to resolve the labels
to concrete locations. This change makes LowerMacros do such a lowering for Switches that can
benefit from jump tables. This happens recursively: if the original Switch is too sparse, we
will divide-and-conquer as before. If at any recursion step we find that the remaining cases
are dense and large enough to profit from a jump table, then those cases will be lowered to a
Patchpoint that does the table jump. This is a fun way to do stepwise lowering: LowerMacros
is essentially pre-lowering the Switch directly to machine code, and wrapping that machine
code in a Patchpoint so that the rest of the compiler doesn't have to know anything about
what happened. I suspect that in the future we will want to do other pre-lowerings this way,
whenever the B3 IR phases have some special knowledge about what machine code should be
emitted and it would be annoying to drag that knowledge through the rest of the compiler.

One downside of this change is that we used ControlValue in so many places. Most of this
patch involves removing references to ControlValue. It would be less than 100kb if it wasn't
for that. To make this a bit easier, I added "appendNewControlValue" methods to BasicBlock,
which allocate a Value and set the successors as if you had done "appendNew<ControlValue>".
This made for an easy search-and-replace in testb3 and FTLOutput. I filed bug 159440 to
remove this ugly stopgap method.

I think that we will also end up using this facility to extend our use of snippets. We
already use shared snippet generators for the generic forms of arithmetic. We will probably
also want to do this for generic forms of branches. This wouldn't have been possible prior to
this change, since there would have been no way to emit a control snippet in FTL. Now we can
emit control snippets using terminal patchpoints.

This is a ~30% speed-up on microbenchmarks that have big switch statements (~60 cases). It's
not a speed-up on mainstream benchmarks.

This also adds a new test to testb3 for terminal Patchpoints, Get, and Set. The FTL does not
currently use terminal Patchpoints directly, but we want this to be possible. It also doesn't
use Get/Set directly even though we want this to be possible. It's important to test these
since opcodes that result from lowering don't affect early phases, so we could have
regressions in early phases related to these opcodes that wouldn't be caught by any JS test.
So, this adds a very basic threaded interpreter to testb3 for a Brainfuck-style language, and
tests it by having it run a program that prints the numbers 1..100 in a loop. Unlike a real
threaded interpreter, it uses a common dispatch block rather than having dispatch at the
terminus of each opcode. That's necessary because PolyJump is not cloneable. The state of the
interpreter is represented using Variables that we Get and Set, so it tests Get/Set as well.

Source/WebCore:

DocType's publicId / systemId should not be nullable. While they were
not marked as nullable in our IDL, they could be stored as null Strings
in our implementation depending on how the Node was constructed. This
led to subtle bugs where String() != emptyString().

In particular, Node.isEqualNode() would return false when DocumentType
nodes would mismatch because of their publicId / systemId being null
instead of the emptyString.

Serialization would DocumentType nodes would also be wrong when
publicId / systemId were empty Strings instead of null strings. The
new behavior now matches:

The function that nulls out the XPC connection, platformInvalidate(), is called from the connection queue,
whereas the XPC connection is normally accessed from the main thread leading to inconsistencies when the

Fix this by simply never nulling out the XPC connection. It will be released when the IPC::Connection is destroyed anyway.

The function daysFrom1970ToYear() takes an integer year and returns a double result.
The calculation uses 1970 as a baseline year and subtracts 1970 from the argument year.
It does that subtraction using integer arithmetic, which given negative years close to
INT_MIN can underflow as a result of subtracting 1970. Since we want a double result,
the fix is to cast year as a double before the subtraction, which eliminates the underflow.

MarkedBlocks should know that they can be used for more than JSCells
https://bugs.webkit.org/show_bug.cgi?id=159643

Reviewed by Geoffrey Garen.

This teaches the Heap that a MarkedBlock may hold either JSCells, or Auxiliary, which is
not a JSCell. It teaches the heap and all of the things that walk the heap to ignore
non-JSCells whenever they are looking for global objects, JSObjects, and things to trace
for debugging or profiling. The idea is that we will be able to allocate butterflies and
typed array backing stores as Auxiliary in MarkedSpace rather than allocating those things
in CopiedSpace. That's what bug 159658 is all about.

This gives us a new type, called HeapCell, which is just meant to be a class distinct from
JSCell or any type we would use for Auxiliary. For convenience, JSCell is a subclass of
HeapCell. HeapCell has an enum called HeapCell::Kind, which is either HeapCell::JSCell or
HeapCell::Auxiliary. MarkedSpace no longer speaks of JSCells directly except when dealing
with destruction.

This change required doing a lot of stuff to all of those functor callbacks, since they
now take HeapCell* instead of JSCell* and they take an extra HeapCell::Kind argument to
tell them if they are dealing with JSCells or Auxiliary. I figured that this would be as
good a time as any to convert those functors to being lambda-compatible. This means that
operator() must be const. In some cases, converting the operator() to be const would have
taken more work than just turning the whole thing into a lambda. Whenever this was the
case, I converted the code to use lambdas. I left a lot of functors alone. In cases where
the functor would benefit from being a lambda, for example because it would get rid of
const_casts or mutables, I put in a FIXME referencing bug 159644.

we will subsequently get foregrounded and re-build the layer tree; in the
background snapshot case, we will just have an empty layer tree.

In the future, we should consider making ApplicationStateTracker use
window context creation/destruction to drive web process lifetime, so
that we can actually paint correctly for background snapshots.

Repeatedly creating and destroying workers that enqueue DFG plans can outpace the DFG worklist, which then causes VM shutdown to stall, which then causes memory growth
https://bugs.webkit.org/show_bug.cgi?id=159754

Reviewed by Geoffrey Garen.

If you create and destroy workers at a high rate and those workers enqueue some DFG plans
that are still not compiled at the time that the worker is closed, then the closed workers
end up stalling in VM::~VM waiting for the DFG worklist thread to finish those plans. Since
we don't actually cancel the plans, it's easy to create a situation where the workers
outpace the DFG worklist, especially if you create many workers at a time and each one
finishes just after enqueueing those plans.

The solution is to allow VM::~VM to remove plans from the DFG worklist that are related to
that VM but aren't currently being worked on. That turns out to be an easy change.

I have a test that repros this, but it's quite long-running. I call it workers/bomb.html. We
may want to exclude it from test runs because of how long it takes.

Object.preventExtensions/seal/freeze makes code much slower
https://bugs.webkit.org/show_bug.cgi?id=143247

Reviewed by Michael Saboff.

Source/JavaScriptCore:

This has been a huge pet peeve of mine for a long time, but I was always afraid of fixing
it because I thought that it would be hard. Well, it looks like it's not hard at all.

The problem is that you cannot mutate a structure that participates in transition caching.
You can only clone the structure and mutate that one. But if you do this, you have to make
a hard choice:

1) Clone the structure without caching the transition. This is what the code did before

this change. It's the most obvious choice, but it introduces an uncacheable transition
that leads to an explosion of structures, which then breaks all inline caches.


2) Perform one of the existing cacheable transitions. Cacheable transitions can either add

properties or they can do one of the NonPropertyTransitions, which until now have been
restricted to just IndexingType transitions. So, only adding transitions or making
certain prescribed changes to the indexing type count as cacheable transitions.


This change decouples NonPropertyTransition from IndexingType and adds three new kinds of
transitions: PreventExtensions, Seal, and Freeze. We have to give any cacheable transition
a name that fully disambiguates this transition from any other, so that the transition can
be cached. Since we're already giving them names in an enum, I figured that the most
pragmatic way to implement them is to have Structure::nonPropertyTransition() case on the
NonPropertyTransition and implement all of the mutations associated with that transition.
The alternative would have been to allow callers of nonPropertyTransition() to supply
something like a lambda that describes the mutation, but this seemed awkward since each
set of mutations has to anyway be tied to one of the NonPropertyTransition members.

This is an enormous speed-up on microbenchmarks that use Object.preventExtensions(),
Object.seal(), or Object.freeze(). I don't know if "real" benchmarks use these features
and I don't really care. This should be fast.

RegisterSet should use a Bitmap instead of a BitVector so that it never allocates memory and is trivial to copy
https://bugs.webkit.org/show_bug.cgi?id=159863

Reviewed by Saam Barati.

Source/JavaScriptCore:

Switch RegisterSet set to Bitmap because Bitmap doesn't ever allocate memory and can be
assigned by memcpy. This should be a performance improvement for compiler code that does a
lot of things with RegisterSet. For example, it's one of the fundamental data structures in
Air. The previous use of BitVector meant that almost every operation on RegisterSet would
have a slow path call. On ARM64, it would mean memory allocation for any RegisterSet that
used all available registers.

This meant adding even more GPR/FPR reflection to the MacroAssembler API: we now have consts
called numGPRs and numFPRs. This is necessary to statically size the Bitmap in RegisterSet.

Here's the breakdown of sizes of RegisterSet on different CPUs:

x86-32: 8 bits (GPRs) + 8 bits (FPRs) + 1 bit (is deleted) = 1x uint32_t.
x86-64: 16 bits + 16 bits + 1 bit = 2x uint32_t.
ARMv7: 16 bits + 16 bits + 1 bit = 2x uint32_t.
ARM64: 32 bits + 32 bits + 1 bit = 3x uint32_t.

DFG and FTL should support op_call_eval
https://bugs.webkit.org/show_bug.cgi?id=159786

Reviewed by Saam Barati.
Source/JavaScriptCore:


This adds support for op_call_eval in DFG and FTL by brute force:

  • There is now a CallEval() node type, which compiles exactly the same way that we do in baseline.


  • We teach the DFG and bytecode liveness that the scope register and 'this' are read by CallEval()/op_call_eval.


We can compile eval quite well, except that right now we cannot inline functions that use
eval. It would be nice to do that, but the payoff is probably smaller. "Don't inline users
of eval" may even be an OK inlining heuristic. Not inlining users of eval allows me to
reuse the baseline implementation, which is really great. Otherwise, I'd have to get rid
of things like the rogue reads of scope register and 'this'.

The goal here is to produce speed-ups for code that has functions that do both eval and
some computational stuff. Obviously, we're not producing any benefit for the eval itself.
But now the other stuff in a function that uses eval will get to participate in
optimization.

This is a huge speed-up on microbenchmarks.

DFG should really support jneq_ptr
https://bugs.webkit.org/show_bug.cgi?id=159700

Reviewed by Keith Miller.

Source/JavaScriptCore:

Prior to this change, DFG statically speculated that jneq_ptr would always fall through. This
meant that programs that called o.apply() or o.call() where apply or call weren't the
expected ones (i.e. the function.prototype.apply/call) would rage-recompile forever.

This adds profiling to jneq_ptr. We now know if it always falls through or sometimes doesn't.
If it sometimes doesn't, we now emit an actual control flow diamond. I decided to add a new
NodeType for "equal pointer", since none of the existing ones really captured that. For
example, there was no way to express "equal pointer" for strings or symbols. We don't use it
for that right now, but we might, and if we did, then it would be hugely surprising that the
DFG interpreted this as value equality. So, the DFG now has CompareEqPtr, which means exactly
what jneq_ptr means by "equal pointer".

This is an enormous speed-up on microbenchmarks. I would assume that it's a speed-up on some
real things, too, but I don't know that for a fact.

OSR entry into DFG has problems with lexical scoping
https://bugs.webkit.org/show_bug.cgi?id=159687

Reviewed by Saam Barati.
Source/JavaScriptCore:


What a fun bug! It turns out that uses of lexical scoping, like "let", may sometimes cause us
to not be able to OSR enter into a loop from baseline to DFG. The bug is in a mitigation for
a different bug, which in turn had a mitigation for yet another bug, so the story here is a
long one.

DFG OSR entry has long had a mitigation for the following bug: the DFG bytecode parser may
choose to make us always OSR exit at some instruction if it thinks that it doesn't have
enough profiling for that instruction. We will do this if some kinds of put_by_id only
execute once, for example. This causes problems for loopy benchmarks like this:

put_by_id(something crazy);
for (var i = 0; i < bigNumber; ++i) simpleMath;


In this case, the put_by_id will have only executed once, and since it did something crazy
that one time, the bytecode parser will replace it with ForceOSRExit.

This creates an OSR entry bug: DFG CFA will then prove that the loop is unreachable, and will
tell OSR entry that it's impossible to enter into that loop.

We mitigated this bug a long time ago by recording mustHandleValues for loops at which we
want to enter. We inject these values into DFG CFA and we force CFA to recognize that the
loop is reachable even if CFA wanted to prove that it wasn't.

But this leads to another bug: we need to scrape the values from the stack inside
operationOptimize() and then we need to reason about them in the compiler. Some of those
values may be garbage, which would cause pandemonium inside the compiler. We also mitigated
this bug, by only recording the "vars", since those are guaranteed to be reset by op_enter.

And that's where the lexical scoping bug happens: "let" bound variables aren't part of the
"vars". DFG will see that they are live, but mustHandleValues will not have anything for
those variables, so CFA will prove that the values are Bottom. Then OSR entry will always
fail because no value is ever a subset of Bottom.

The first part of the fix is to ensure that mustHandleValues record all of the values on the
stack (i.e. within m_numCalleeLocals, rather than just m_numVars). But this creates a second
problem: we may record garbage. This patch includes a better fix for the garbage: before
touching mustHandleValues we run the bytecode liveness analysis and clear any values that are
not live. This ensures that we clear the garbage.

This is an enormous speed-up on microbenchmarks that use lexical scoping and have some crazy
put_by_id in the lead-up to the hot loop.

WTF::Lock should be fair eventually
https://bugs.webkit.org/show_bug.cgi?id=159384

Reviewed by Geoffrey Garen.
Source/WTF:


In https://webkit.org/blog/6161/locking-in-webkit/ we showed how relaxing the fairness of
locks makes them fast. That post presented lock fairness as a trade-off between two
extremes:

  • Barging. A barging lock, like WTF::Lock, releases the lock in unlock() even if there was a thread on the queue. If there was a thread on the queue, the lock is released and that thread is made runnable. That thread may then grab the lock, or some other thread may grab the lock first (it may barge). Usually, the barging thread is the thread that released the lock in the first place. This maximizes throughput but hurts fairness. There is no good theoretical bound on how unfair the lock may become, but empirical data suggests that it's fair enough for the cases we previously measured.


  • FIFO. A FIFO lock, like HandoffLock in ToyLocks.h, does not release the lock in unlock() if there is a thread waiting. If there is a thread waiting, unlock() will make that thread runnable and inform it that it now holds the lock. This ensures perfect round-robin fairness and allows us to reason theoretically about how long it may take for a thread to grab the lock. For example, if we know that only N threads are running and each one may contend on a critical section, and each one may hold the lock for at most S seconds, then the time it takes to grab the lock is N * S. Unfortunately, FIFO locks perform very badly in most cases. This is because for the common case of short critical sections, they force a context switch after each critical section if the lock is contended.


This change makes WTF::Lock almost as fair as FIFO while still being as fast as barging.
Thanks to this new algorithm, you can now have both of these things at the same time.

This change makes WTF::Lock eventually fair. We can almost (more on the caveats below)
guarantee that the time it takes to grab a lock is N * max(1ms, S). In other words, critical
sections that are longer than 1ms are always fair. For shorter critical sections, the amount
of time that any thread waits is 1ms times the number of threads. There are some caveats
that arise from our use of randomness, but even then, in the limit as the critical section
length goes to infinity, the lock becomes fair. The corner cases are unlikely to happen; our
experiments show that the lock becomes exactly as fair as a FIFO lock for any critical
section that is 1ms or longer.

The fairness mechanism is broken into two parts. WTF::Lock can now choose to unlock a lock
fairly or unfairly thanks to the new ParkingLot token mechanism. WTF::Lock knows when to use
fair unlocking based on a timeout mechanism in ParkingLot called timeToBeFair.

ParkingLot::unparkOne() and ParkingLot::parkConditionally() can now communicate with each
other via a token. unparkOne() can pass a token, which parkConditionally() will return. This
change also makes parkConditionally() a lot more precise about when it was unparked due to a
call to unparkOne(). If unparkOne() is told that a thread was unparked then this thread is
guaranteed to report that it was unparked rather than timing out, and that thread is
guaranteed to get the token that unparkOne() passed. The token is an intptr_t. We use it as
a boolean variable in WTF::Lock, but you could use it to pass arbitrary data structures. By
default, the token is zero. WTF::Lock's unlock() will pass 1 as the token if it is doing
fair unlocking. In that case, unlock() will not release the lock, and lock() will know that
it holds the lock as soon as parkConditionally() returns. Note that this algorithm relies
on unparkOne() invoking WTF::Lock's callback while the queue lock is held, so that WTF::Lock
can make a decision about unlock strategy and inject a token while it has complete knowledge
over the state of the queue. As such, it's not immediately obvious how to implement this
algorithm on top of futexes. You really need ParkingLot!

WTF::Lock does not use fair unlocking every time. We expose a new API, Lock::unlockFairly(),
which forces the fair unlocking behavior. Additionally, ParkingLot now maintains a
per-bucket stochastic fairness timeout. When the timeout fires, the unparkOne() callback
sees UnparkResult::timeToBeFair = true. This timeout is set to be anywhere from 0ms to 1ms
at random. When a dequeue happens and there are threads that actually get dequeued, we check
if the time since the last unfair unlock (the last time timeToBeFair was set to true) is
more than the timeout amount. If so, then we set timeToBeFair to true and reset the timeout.
This means that in the absence of ParkingLot collisions, unfair unlocking is guaranteed to
happen at least once per millisecond. It will happen at 2 KHz on average. If there are
collisions, then each collision adds one millisecond to the worst case (and 0.5 ms to the
average case). The reason why we don't just use a fixed 1ms timeout is that we want to avoid
resonance. Imagine a program in which some thread acquires a lock at 1 KHz in-phase with the
timeToBeFair timeout. Then this thread would be the benefactor of fairness to the detriment
of everyone else. Randomness ensures that we aren't too fair to any one thread.

Empirically, this is neutral on our major benchmarks like JetStream but it's an enormous
improvement in LockFairnessTest. It's common for an unfair lock (either our BargingLock, the
old WTF::Lock, any of the other futex-based locks that barge, or new os_unfair_lock) to
allow only one thread to hold the lock during a whole second in which each thread is holding
the lock for 1ms at a time. This is because in a barging lock, releasing a lock after
holding it for 1ms and then reacquiring it immediately virtually ensures that none of the
other threads can wake up in time to grab it before it's relocked. But the new WTF::Lock
handles this case like a champ: each thread gets equal turns.

Here's some data. If we launch 10 threads and have each of them run for 1 second while
repeatedly holding a critical section for 1ms, then here's how many times each thread gets
to hold the lock using the old WTF::Lock algorithm:

799, 6, 1, 1, 1, 1, 1, 1, 1, 1

One thread hogged the lock for almost the whole time! With the new WTF::Lock, the lock
becomes totally fair:

80, 79, 79, 79, 79, 79, 79, 80, 80, 79

I don't know of anyone creating such an automatically-fair adaptive lock before, so I think
that this is a pretty awesome advancement to the state of the art!

This change is good for three reasons:

  • We do have long critical sections in WebKit and we don't want to have to worry about starvation. This reduces the likelihood that we will see starvation due to our lock strategy.


  • I was talking to ggaren about bmalloc's locking needs, and he wanted unlockFairly() or lockFairly() or some moral equivalent for the scavenger thread.


  • If we use a WTF::Lock to manage heap access in a multithreaded GC, we'll need the ability to unlock and relock without barging.

MemoryPressureHandler doesn't work if cgroups aren't present in Linux
https://bugs.webkit.org/show_bug.cgi?id=155255

Reviewed by Sergio Villar Senin.

Source/WebCore:

Allow to pass an eventFD file descriptor to the MemoryPressureHandler to be monitorized in case cgroups are not
available.

  • platform/MemoryPressureHandler.h:
  • platform/linux/MemoryPressureHandlerLinux.cpp:

Source/WebKit2:

There's no way to get notifications about memory pressure in Linux without using cgroups that doesn't require a
manual polling. We can get that information from /proc/meminfo, but that's not pollable so it requires to
manually check its contents in a loop sleeping for a while between checks. This means we would be waking up the
process on every poll iteration, most of the times for nothing. That's specially problematic on devices running
on battery. And taking into account that there's a memory pressure handler in every secondary process (Web,
Network and Plugin), we would be waking up all those process all the time. However, not having a memory pressure
handler is even more problematic than the manual polling.
This patch adds a class MemoryPressureMonitor to the manual polling of /proc/meminfo, but runs in the UI
process, to avoid the weakups in all other secondary processes, and uses an eventFD to notify all other
processes. It's only used in case cgroups is not available. The eventFD descriptor is sent to all other
processes at startup, and passed to the MemoryPressureHandler before install() is called for the first
time. To minimize the wakeups even in the UI process, the poll interval is calculated from 1 to 5 seconds
depending on the current memory used, so in case of low memory level we sleep for a longer time.
It's also important to make the memory calculations as accurate as possible to avoid cleaning resources in the
secondary processes unnecessarily.

DFG CSE is broken for MultiGetByOffset
https://bugs.webkit.org/show_bug.cgi?id=159858

Reviewed by Saam Barati.

This disabled CSE for MultiGetByOffset. I opened bug 159859 for the long-term fix, which
would teach CSE (and other passes also) how to decay a removed MultiGetByOffset to a
CheckStructure. Since we currently just decay MultiGetByOffset to Check, we forget the
structure checks. So, if we CSE a MultiGetByOffset that checks for one set of structures with
a heap access on the same property and base that checks for different structures, then we
will forget some structure checks that we had previously. It's unsound to forget checks in
DFG IR.

This bug mostly manifested as a high-volume crash at Unreachable in FTL, because we'd prove
that the code after the MultiGetByOffset was unreachable due to the structure checks and then
CSE would remove everything but the Unreachable.

  • dfg/DFGClobberize.h:

(JSC::DFG::clobberize): Remove the def() for MultiGetByOffset to disable CSE for this node for now.

  • tests/stress/cse-multi-get-by-offset-remove-checks.js: Added. This used to fail with FTL eanbled.

When a view is removed from it's superview, and that superview's constraints property references
the removed superview, those constraints are removed as well. Make sure to save off a copy of
the superview's constraints before swapping in the placeholder view, and reapply those constraints
when swapping the web view back into its original superview.

[JSC] Enable test262 module tests
https://bugs.webkit.org/show_bug.cgi?id=159854

Reviewed by Saam Barati.

Source/JavaScriptCore:

This patch enables test262 module tests. Before this patch, the modules tests in test262 do not work fine.
This patch fixes the following 2 things.

  1. Test harness

Before this patch, there is only one global switch "-m" in jsc shell. So we cannot load the test262 test harness before evaluating the module tests.
This patch adds a new option, "--module-file=". It is similar to "--strict-file=". When we specify the file with "--module-file=", it is evaluated as
a module, while the other files are evaluated by following the JSC's default manner. This option allows us to load the test harness files into the
global context before loading the module tests.

  1. Module's asynchronous errors

Before this patch, the errors caused in the module evaluation are not handled as the same to the usual sync files. In synchronous execution, we have
"--exception=" option to pass the expected exception to the JSC shell. But this option does not work in the module evaluation.
This patch correctly handles this expected exception in the module evaluation promise's fulfill and reject handlers.

And we fix the YAML file. Now the recorded :fail and :normal are the correct test results for the module tests.

[JSC] Mask TrustedImm32 to 8bit in MacroAssembler for 8bit operations
https://bugs.webkit.org/show_bug.cgi?id=159334

Reviewed by Filip Pizlo.

Previously, in 8bit operations (like add8, compare8, test8, branch8, branchTest8 etc.),
we require that the given TrustedImm32 is in range of 8bit. While achieving this in
the manual MacroAssembler calling is easy, in Air, we don't guarantee that the higher bit
of the 8bit argument is cleared. So the current assertions are invalid.

This patch relaxes the above restriction. By removing this assertion,
8bit operations can take arbitrary 32bit imms. And only lower 8bit are effective when
emitting the code in these methods.

Support new emoji group candidates
https://bugs.webkit.org/show_bug.cgi?id=159755
<rdar://problem/27325521>

Reviewed by Dean Jackson.

Source/WebCore:

There are a few code points which should be able to be joined (with ZWJ) to
either U+2640 or U+2642 to change the gender of the emoji. These patterns
should also work with an additional 0xFE0F variation selector. This patch
adds these new patterns to our existing emoji group candidate infrastructure.

This patch doesn't update the rules for our cursor movement iterator, because
I don't know the language used for implementing these rules. These rules will
be updated in the near future. When they do,
editing/deleting/delete-emoji-expected.txt will need to be updated.

LayoutTests:

Because this patch doesn't update the rules for our cursor movement
iterator, the new expected result for editing/deleting/delete-emoji.html
expects incorrect results. In the patch where we update these rules,
the expected result should also be updated.

Because these new emoji require system support, TestExpectations has
been updated to mark the tests as failing until the system support has
been added.
