Context Navigation

Scrollable elements that place their vertical scrollbar on the left
(e.g. when they're direction: rtl or when the OS language is RTL and
the relevant setting to always follow OS scrollbar side is used) have
an incorrect scroll origin, which leads to creating a horizontal
scrollbar with an incorrect initial offset. This is because
RenderLayerScrollableArea::computeScrollDimensions runs prior to the
scrollbars being created. So whenever we start or stop having a
(non-overlay) vertical scrollbar on the left, we need to recompute
the scroll origin and fix up the horizontal scrollbar's offset.

(WebCore::RenderLayerScrollableArea::computeScrollOrigin): Split this
out of computeScrollDimensions so we can call it from
updateScrollbarsAfterLayout and updateScrollbarsAfterStyleChange, and
have it ask the horizontal scrollbar to update its offset. We could
condition this on the scroll origin actually having changed, but
that's going to be a similar check that Scrollbar::offsetDidChange
does to ensure the offset value did indeed change. We don't want to
condition this on shouldPlaceBlockDirectionScrollbarOnLeft(), since
that's dependent on the current style, and we may be reacting to a
style change removed the vertical scrollbar on the left.

Update test result now that it is passing.

Source/WebCore:

Re-implement proper (not using named-getters) support for the CSSStyleDeclaration bindings
using a new DelegateToSharedSyntheticAttribute extended atttribute which allows IDL attributes
to share a custom getter / setter implementation and delegate their implementation to it. When
using this functionality, the synthetic attribute's implementation is passed the original property
name so it can implement functionality based on it.

We use this for CSSStyleDeclaration by breaking the huge list of generated properties into
four groups, each with their own synthetic attribute. The groups are based on the different
transformation rules in the spec.

Crash under WebProcessProxy::shouldSendPendingMessage()
https://bugs.webkit.org/show_bug.cgi?id=224377
<rdar://75329251>

Reviewed by David Kilzer.

We are crashing with a null-dereference of pendingMessage.encoder inside WebProcessProxy::shouldSendPendingMessage().
However, pendingMessage.encoder is a UniqueRef<> and thus cannot be null. Also, we know that the WebProcessProxy
is alive because WebProcessProxy::didFinishLaunching() has a protector.

One thing that I believe could theoretically happen and would not be safe though is AuxiliaryProcessProxy::sendMessage()
being called on a non-main thread. Sending IPC off the main thread is safe in general and something we commonly do with
an IPC::Connection. To make this safe, IPC::Connection uses a Lock to protect its vector of messages. However, sending
IPC via an AuxiliaryProcessProxy is currently not thread safe as it relies on the process state (which gets updated on
the main thread) and access to the m_pendingMessages is not synchronized.

As a speculative fix, I have added logic in AuxiliaryProcessProxy::sendMessage() to dispatch to the main thread if
we're not already on it. I have also used WTF::DestructionThread::MainRunLoop to make sure all AuxiliaryProcessProxy
objects get destroyed on the main thread.

In a follow-up, I am planning to add a release assertion in AuxiliaryProcessProxy::sendMessage() to make sure we're
on a main thread. We'll then be able to drop the "dispatching the main thread" logic. For now though, I think we
should start with the "dispatch to main thread" logic, so that we have a patch that we can cherry-pick to a branch.

[JSC] detect infrastructure failure for remote stress tests
https://bugs.webkit.org/show_bug.cgi?id=222601

Reviewed by Yusuke Suzuki.

run-jsc-stress-tests currently detects failures by the absence of
a failure file (that is generated by each failing test). This is
fragile to begin with, as it assumes that tests that fail to run
(e.g. because of an error in the runner script) are successful by
default.

However, the main motivation for this patch is to make execution
more robust when using remote hosts. Currently,
--gnu-parallel-runner will transparently reschedule jobs on a
different host when a remote host goes away. But detectFailures
expects to be able to connect to all hosts and fetch the failure
files, which fails if a remote host is still down when the run
finishes.

Instead, this patch changes the runners to always generate a status
file with the exit code. detectFailures then fetches all status
files from all hosts that are live on exit. Tests that failed to
run are explicitly accounted for as 'noreport' and are set to
ERROR in the final report.

Reviewed by Mark Lam.

When reducing double-constant value to float in B3, we should check whether the double value is a canonical one
which can be converted back from the reduced float value. For example, double 1.1 is not the one since it is truncated
into float 1.1 by removing some bits.

static_cast<double>(static_cast<float>(1.1)) != 1.1

Reducing such a double to float changes the semantics.

Enable VMTraps checks in RETURN_IF_EXCEPTION.
https://bugs.webkit.org/show_bug.cgi?id=224078
rdar://75037057

Reviewed by Keith Miller.

JSTests:

stress/watchdog-fire-while-in-forEachInIterable.js: Added.

Source/JavaScriptCore:

In pre-existing code, termination of a VM's execution can already be requested
asynchronously (with respect to the mutator thread). For example, sources of such
a request can be a watchdog timer firing, or a request to stop execution issued
from a main web thread to a worker thread.

This request is made by firing the VMTraps::NeedTermination event on VMTraps.
Firing the event here only means setting a flag to indicate the presence of the
request. We still have to wait till the mutator thread reaches one of the
pre-designated polling check points to call VMTraps::handleTraps() in order to
service the request. As a result of this need to wait for a polling check point,
if the mutator is executing in a long running C++ loop, then a termination request
may not be serviced for a long time.

However, we observed that a lot of our C++ loops already have RETURN_IF_EXCEPTION
checks. Hence, if we can check VMTraps::needHandling() there, we can service the
VMTraps events more frequently even in a lot of C++ loops, and get a better response.

Full details of what this patch changes:

Shorten some type and methods names in the VMTraps class to make code easier to read e.g. EventType => Event, needTrapHandling => needHandling.

Remove the VMTraps::Mask class. Mask was introduced so that we can express a concatenation of multiple VMTraps events to form a bit mask in a simple way. In the end, it isn't flexible enough but makes the code more complicated than necessary. It is now replaced by the simpler solution of using macros to define the Events as bit fields. Having Events as bit fields intrinsically make them easy to concatenate (bitwise or) or filter (bitwise and).

Also removed the unused VMTraps::Error class.

Make VMTraps::BitField a uint32_t. There was always unused padding in VMTraps to allow for this. So, we'll just extend it to a full 32-bit to make it easier to add more events in the future for other uses.

Add NeedExceptionHandling as a VMTrap::Event.

Make VMTraps::m_trapBits Atomic. This makes it easier to set and clear the NeedExceptionHandling bit from the mutator without a lock.

RETURN_IF_EXCEPTION now checks VMTraps::m_trapBits (via VMTraps::needHandling()) instead of checking VM::m_exception. If the VMTraps::m_trapBits is non-null, the macro will call VM:hasExceptionsAfterHandlingTraps() to service VMTraps events as appropriate before returning whether an exception is being thrown. The result of VM:hasExceptionsAfterHandlingTraps() will determine if RETURN_IF_EXCEPTION returns or not.

VM:hasExceptionsAfterHandlingTraps() is intentionally designed to take a minimum
of arguments (just the VM as this pointer). This is because RETURN_IF_EXCEPTION
is called from many places, and we would like to minimize code size bloating
from this change.

Simplify paramaters of VMTraps::handleTraps().

NeedDebuggerBreak's callFrame argument was always vm.topCallFrame anyway.
So, the patch makes it explicit, and removes the callFrame parameter.

NeedWatchdogCheck's globalObject argument should have always been
vm.entryScope->globalObject(), and we can remove the globalObject parameter.

Before this, we pass in whichever globalObject was convenient to grab hold of.
However, the idea of the watchdog is to time out the current script executing
on the stack. Hence, it makes sense to identify thay script by the globalObject
in use at VM entry.

So far, the only clients that uses the watchdog mechanism only operates in
scenarios with only one globalObject anyway. So this formalization to use
VMEntryScope's globalObject does not change the expected behavior.

Make the execution of termination more robust. Before reading this, please read the description of the Events in VMTraps.h first, especially the section on NeedTermination.

Here's the life cycle of a termination:

a client requests termination of the current execution stack by calling VM::notifyNeedTermination(). notifyNeedTermination() does 2 things:

fire the NeedTermination event on VMTraps.

set the VM::m_terminationInProgress flag.

Firing the NeedTermination event on VMTraps means setting the NeedTermination bit on VMTraps::m_trapBits. This bit will be polled by the mutator thread later at various designated points (including RETURN_IF_EXCEPTION, which we added in this patch).

Once the mutator sees the NeedTermination bit is set, it will clear the bit
and throw the TerminationException (see VMTraps::handleTraps()). This is
unless the mutator thread is currently in a DeferTermination scope (see (8)
below). If in a DeferTermination scope, then it will not throw the
TerminationException.

Since the NeedTermination bit is cleared, the VM will no longer call
VMTraps::handleTraps() to service the event. If the mutator thread is in
a DeferTermination scope, then on exiting the scope (at scope destruction),
the scope will see that VM::m_terminationInProgress is set, and throw the
deferred TerminationException then.

The TerminationException will trigger unwinding out of the current stack until we get to the outermost VMEntryScope.

At the the outermost VMEntryScope, we will clear VM::m_terminationInProgress if the NeedTermination bit in VMtraps::m_trapBits is cleared.

If the NeedTermination bit is set, then that means we haven't thrown the
TerminationException yet. Currently, clients expect that we must throw the
TerminationException if NeedTermination was requested (again, read comments
at the top of VMTraps.h).

If the NeedTermination bit is set, we'll leave VM::m_terminationInProgress
set until the next time we re-enter the VM and exit to the outermost
VMEntryScope.

The purpose of VM::m_terminationInProgress is to provide a summary of the fact that the VM is in a state of trying to terminate the current stack.

Note that this state is first indicated by the NeedTermination bit being set
in VMTraps::m_trapBits. Then, in VMTraps::handleTraps(), the state is
handed of with the NeedTermination bit being cleared, and the
TerminationException being thrown.

While the VM is in this termination state, we need to prevent new DFG/FTL
JIT code from being compiled and run. The reason is the firing of the
NeedTermination event has invalidated DFG/FTL code on the stack, thereby
allowing their baseline / LLInt versions which have VMTraps polling checks
to run. We don't want to compile new DFG / FTL code and possibly get stuck
in loops in there before the termination is complete.

In operationOptimize(), we check if VM::m_terminationInProgress is set, and
prevent new DFG (and therefore FTL) code from being compiled if needed.
Note: it is easier to check a single flag, VM::m_terminationInProgress,
then to check both if the NeedTermination bit is set or if the
TerminationException is being being thrown.

One complication of being able to service VMTraps in RETURN_IF_EXCEPTION checks is that some of our code (usually for lengthier initializations and bootstrapping) currently does not handle exceptions well, e.g. JSGlobalObject::init(). They rely on the code crashing if an exception is thrown while still initializing.

However, for a worker thread, a TerminationException (requested by the main
thread) may arrive before the initialization is complete. This can lead to
crashes because part of the initialization may be aborted in the presence of
an exception, while other parts still expect everything prior to have been
initialized correctly. For resource exhaustion cases (which is abnormal), it
is OK to crash. For the TerminationException (which can be part of normal
operation), we should not be crashing.

To work around this, we introduce a DeferTermination RAII scope object that we
deploy in this type of initialization code. With the scope in effect,

if a TerminationException arrives but hasn't been thrown yet, it will be deferred till the scope ends before being thrown.
if a TerminationException has already been thrown, the scope will stash the exception, clear it from the VM so that the initialization code can run to completion, and then re-throw the exception when the scope ends.

Currently, we only need to use the DeferTermination scope in a few places
where we know that initialization code will only run for a short period of time.

DeferTermination should not be used for code that can block waiting on an
external event for a long time. Obviously, doing so will prevent the VM
termination mechanism from working.

Replaced llint_slow_path_check_if_exception_is_uncatchable_and_notify_profiler

and operationCheckIfExceptionIsUncatchableAndNotifyProfiler with
llint_slow_path_retrieve_and_clear_exception_if_catchable and
operationRetrieveAndClearExceptionIfCatchable.

The 2 runtime functions doesn't actually do anything to notify a profiler.
So, we drop that part of the name.

After returning from these runtime functions respectively, the previous LLInt
and JIT code, which calls these runtimes functions, would go on to load
VM::m_exception, and then store a nullptr there to clear it. This is wasteful.

This patch changes the runtime function to clear and return the Exception
instead. As a result, the calling LLInt and JIT code is simplified a bit.

Note also that clearing an exception now also entails clearing the
NeedExceptionHandling bit in VMTraps::m_trapBits in an atomic way. The above
change makes it easy to do this clearing with C++ code.

Fix ScriptFunctionCall::call() to handle exceptions correctly. Previously,

it had one case where it propagates an exception, while another eats it.
Change this function to eat the exception in both cases. This is approproiate
because ScriptFunctionCall is only used to execute some Inspector instrumentation
calls. It doesn't make sense to propagate the exception back to user code.

Fix the lazy initialization of JSGlobalObject::m_defaultCollator to be able to

handle the TerminationException.

Not related to TerminationException, but this patch also fixes

MarkedArgumentBuffer::expandCapacity() to use Gigacage::tryMalloc() instead of
Gigacage::malloc(). This is needed as one of the fixes to make the
accompanying test case work.

This patch increases code size by 320K (144K for JSC, 176K for WebCore) measured
on x86_64.

When RemoteLayerTreeDrawingArea called windowScreenDidChange() from its constructor,

Fix by sending windowScreenDidChange() from the UI process, with the synthetic
DisplayID generated from the webPageID(). This has the advantage that
WebPageProxy will also store the correct DisplayID, and is more similar to macOS.

REGRESSION (r271660): Tap highlight no longer shows when tapping clickable elements without touch event listeners
https://bugs.webkit.org/show_bug.cgi?id=224385
<rdar://problem/76462370>

Reviewed by Tim Horton.

Source/WebKit:

In r271660, I added a call to -finishInteraction when resetting the synthetic tap gesture to fix a bug where
it was possible for the tap highlight to remain indefinitely when tapping on a clickable element with a touchend
event listener. This was because the touch end deferring gesture defers -_singleTapDidReset: until after
-_didGetTapHighlightForRequest:…nodeHasBuiltInClickHandling:, where we receive the tap highlight information.

`
2021-04-09 13:05:27.141097-0700 -[WKContentView(WKInteraction) _singleTapIdentified:]
2021-04-09 13:05:27.148678-0700 -[WKContentView(WKInteraction) _didGetTapHighlightForRequest:…nodeHasBuiltInClickHandling:]

2021-04-09 13:05:51.849481-0700 ↳ -[WKContentView(WKInteraction) _finishInteraction]
`

However, in the case where there is no touchend event listener and when fast-click is active, we reset the tap
gesture before receiving the tap highlight information:

`
2021-04-09 13:05:51.836638-0700 -[WKContentView(WKInteraction) _singleTapIdentified:]
2021-04-09 13:05:51.846152-0700 -[WKContentView(WKInteraction) _singleTapRecognized:]

2021-04-09 13:05:51.849481-0700 ↳ -[WKContentView(WKInteraction) _finishInteraction]

Critically, this means that calling -_finishInteraction in -_singleTapDidReset: prematurely flagged the
tap highlight request as complete (by setting _isTapHighlightIDValid to NO) in the case where we aren't
deferring gestures, which caused us to avoid showing the tap highlight at all when we eventually receive the tap
highlight information.

To fix this, only fade out the tap highlight view in -_singleTapDidReset: if the tap highlight request has
already finished (i.e. _isTapHighlightIDValid has been set to NO). Additionally, split logic for fading out
the highlight view into a separate method, and add a BOOL flag to make the fading idempotent.

Remove className() and toStringName() from the method table
https://bugs.webkit.org/show_bug.cgi?id=224247

Reviewed by Darin Adler.

Source/JavaScriptCore:

ES6 introduced Symbol.toStringTag to customize Object.prototype.toString return value.
It was adopted by WebIDL spec, Chrome's DevTools, Node.js etc. There is no reason to
keep 2 method table methods, each with only 1 call site, instead of using the symbol.

Also, it's a bit confusing that for some objects, method table's className() returns
different result than JSCell::className(VM&).

This change:

Removes JSProxy's className() / toStringName() methods because its target() is a global object that never has these overrides and uses Symbol.toStringTag instead.

Removes DebuggerScope's className() / toStringName() overrides because its objectAtScope() has these methods extremely rarely (e.g. with (new Date) {}), and its not displayed by Web Inspector.

Merges JSCallbackObject's className() / toStringName() methods into Symbol.toStringTag branch of getOwnPropertySlot(), with permissive property attributes. To avoid any possible breakage, we make sure that it will be shadowed by a structure property.

Reworks JSObject::calculatedClassName() to rely on Symbol.toStringTag, matching Chrome's DevTools behavior. On its own, it's a nice change for Web Inspector. We make sure to lookup Symbol.toStringTag if constructor.name inference fails to avoid confusion when extending builtins.

Removes now unused className() from the method table.

Removes toStringName() override from JSFinalizationRegistry because its builtin tag [1] is already "Object".

Introduces BooleanObjectType for Boolean wrapper object, and Boolean.prototype as it's also required to have a BooleanData? internal slot [2].

Reworks Object.prototype.toString to determine builtin tag [1] based on JSType rather than performing method table call. It's guaranteed that a) the set of types we are checking against won't be expanded, and b) objects with these types have correct className.

Removes now unused toStringTag() from the method table.

This patch is performance-neutral and carefully preserves current behavior for API objects,
including isPokerBros() hack.

Media Session action should default to the MediaElement's default when no MediaSession handler are set
https://bugs.webkit.org/show_bug.cgi?id=224278
<rdar://problem/76339841>

Reviewed by Youenn Fablet .

Source/WebCore:

When a media session doesn't explicitly define an action handler, we use the media element
default action of the same type.
Media Session doesn't track a particular media element, instead it loosely defines a guessed playback state
that tracks if some element in the current document is playing and not muted or otherwise paused.
(see https://w3c.github.io/mediasession/#playback-state-model)
We therefore need to determine what is currently the most suitable media element available in this document.
Unlike the Media Controller and the Now Playing policy that will only ever select a media
if it is currently playing and not muted, for the Media Session we may have to interact with paused media elements.
For this we add a new PlaybackControlsPurpose named MediaSession defining new search criterias.
A media element will be up for selection if it's playable (according to autoplay policy). From then,
the best element will be selected accoring to its visibility, its size, if it's beeing played previously and
the last time it was interacted with.

Web process crashes if image extraction is requested for an element that is pending image extraction
https://bugs.webkit.org/show_bug.cgi?id=224397
<rdar://problem/76472254>

Reviewed by Tim Horton.

Add a missing null check, so that we don't append (and then end up attempting to call) a null completion handler
in the case where image extraction is re-requested for an element that already has a pending image extraction
request.

This is currently not possible to reliably test this; in a future patch, I will add testing infrastructure that
will allow us to simulate image extraction requests and responses at the client layer.

[Cairo][GPUP] GraphicsContextGLOpenGL::paintToCanvas can't paint into a remote canvas
https://bugs.webkit.org/show_bug.cgi?id=224271

Reviewed by Don Olmstead.

WebGL canvas tests were failing for WinCairo port since r274327
enabled GPU process for canvas rendering. In the current
implementation of WebKitTestRunner, 2D canvases are in GPU
process, while WebGL canvases are in WebContent process. Remote
canvases in GPU process failed to drawImage() with a WebGL canvas
what is in WebContent process.

GraphicsContextGLOpenGL::paintToCanvas of Cairo port was painting
directly into PlatformContextCairo. It also should use
GraphicsContext::drawNativeImage as well as CG port does.

Create WebIDBServer only when it is needed
https://bugs.webkit.org/show_bug.cgi?id=224305
rdar://71962196

Reviewed by Alex Christensen.

Currently each WebIDBServer comes with a thread, so we don't want to keep WebIDBServer if it's not in use.
Now there are two cases where network process needs a WebIDBServer:

handle requests from UI process to collect or remove data
handle requests from Web process to perform IDB operations

We created a WebIDBServer when network process connects to a web process, and we should create it when
web process is about to perform IDB operations. Also, we should remove WebIDBServer if it's done handling
requests, i.e count of pending requests from UI process is 0 and WebIDBServer is not associated with any web
process connection.

Make TestInput take a Test object, not a path
https://bugs.webkit.org/show_bug.cgi?id=224329

Reviewed by Jonathan Bedard.

Scripts/webkitpy/layout_tests/controllers/layout_test_runner.py:

(LayoutTestRunner.run_tests): Remove test_to_skip argument; skipped tests aren't for the runner.

Scripts/webkitpy/layout_tests/controllers/layout_test_runner_unittest.py:

(LayoutTestRunnerTests._run_tests): TestInput expects a Test.
(LayoutTestRunnerTests.test_interrupt_if_at_failure_limits): TestInput expects a Test.
(SharderTests.get_test_input): TestInput expects a Test.

Scripts/webkitpy/layout_tests/controllers/manager.py:

(Manager._collect_tests):
Move duplicated code from Manager.run and Manager.print_expectations here.
(Manager._tests_to_run):
Renamed from Manager._prepare_lists; now just gives tests to run.
(Manager._test_input_for_file): Now takes a Test, not a str; device_type changes behaviour and shouldn't have any default.
(Manager._test_is_slow): device_type changes behaviour and shouldn't have any default.
(Manager._test_should_dump_jsconsolelog_in_stderr): device_type changes behaviour and shouldn't have any default.
(Manager._get_test_inputs): device_type changes behaviour and shouldn't have any default.
(Manager._update_worker_count): device_type changes behaviour and shouldn't have any default.
(Manager._set_up_run): device_type changes behaviour and shouldn't have any default.
(Manager.run):
Largely just change for Manager._collect_tests, also renaming the sets to match their
clearer names in print_expectations.
Additionally, now generate skip results here, as they aren't to do with actually running
tests, they're about test selection.
(Manager._run_test_subset): Remove tests_to_skip argument, devie_type is required.
(Manager._run_tests): Remove tests_to_skip argument, devie_type is required.
(Manager._print_expectation_line_for_test): Now takes a Test, not a str; device_type changes behaviour and shouldn't have any default.
(Manager._print_expectations_for_subset): Change default of tests_to_skip to avoid set/dict oddness.
(Manager.print_expectations): Largely change for Manager._collect_tests.

Scripts/webkitpy/layout_tests/models/test.py:

(Test): Use attrs to avoid having to define cmp, hash, repr, etc.

Scripts/webkitpy/layout_tests/models/test_input.py:

(TestInput.init): Take a Test, not a str.
(TestInput.test_name): Maintain compatibility with code reading TestInput.test_name for now.

Scripts/webkitpy/layout_tests/models/test_run_results.py:

(TestRunResults.merge): Fix merging of dicts-of-sets, rather than overwriting the sets.
(TestRunResults.merge.merge_dict_sets): Implement the merging.

[css-grid] Set hasIntrinsicWidth & hasIntrinsicHeight properties for SVG element's intrinsic size
https://bugs.webkit.org/show_bug.cgi?id=223504

Patch by Ziran Sun <Ziran Sun> on 2021-04-09
Reviewed by Javier Fernandez.

Source/WebCore:

In RenderReplaced::computeReplacedLogicalWidth/RenderReplaced::computeReplacedLogicalHeight(),
hasIntrinsicWidth and hasIntrinsicHeight are decided by whether the value is bigger than 0.
This is not alway true. The SVG element sets its hasIntrinsicWidth/hasIntrinsicHeight property
in line with its lengthType(). This change adds checks for SVG element cases specifically.

platform/graphics/FloatSize.h:
rendering/RenderReplaced.cpp:

(WebCore::RenderReplaced::computeReplacedLogicalWidth const):
(WebCore::RenderReplaced::computeReplacedLogicalHeight const):

rendering/svg/RenderSVGRoot.cpp:

(WebCore::RenderSVGRoot::computeIntrinsicRatioInformation const):

LayoutTests:

Enable 4 tests that pass now.

[ macOS wk2 ARM64 ] fast/images/async-image-background-change.html is a flakey timeout
https://bugs.webkit.org/show_bug.cgi?id=223469

Reviewed by Darin Adler.

If the event 'webkitImageFrameReady' fires before registering its listener,
the test will timeout.

Make sure the event listener is registered before changing the background
of the element.

Need to propagate and use 'canShowWhileLocked' in the GPU Process
https://bugs.webkit.org/show_bug.cgi?id=224345
<rdar://76011262>

Reviewed by Tim Horton.

The GPUProcess was previously creating a single visibility propagation view even though
it was potentially serving several web views. Also, it would also pass
canShowWhileLocked=false when constructing the visibility propagation view, ignoring
the value of WKWebViewConfiguration._canShowWhileLocked. This would lead to issues for
apps relying on WKWebView to show content on the lock screen.

To address the issue, we now have the RemoteRenderingBackend construct its own
visibility propagation view in the GPUProcess. The GPUProcess constructs a
RemoteRenderingBackend per WebPage being served so this is convenient. When sending the
IPC to the GPUProcess to construct the RemoteRenderingBackend, the WebProcess now sends
the page identifier as well as the value of the canShowWhileLocked flag so that we
can use the correct canShowWhileLocked flag when constructing the visibility propagation
view.

The logic in the UIProcess for dealing with GPUProcess visibility propagation views
is now almost identical to WebProcess visibility propagation views. They are stored on
the WebPageProxy and get swapped on process-swap (since a new WebPage gets created).

Expose _isShowingDatalistSuggestions for testing. Previously, the test

Note that focusing text fields can result in automatic zooming of the
webview. This zooming occurs after an editor state update for focused
elements. The presentation of the context menu is deferred to run
after an editor state update to ensure any zooming occurs before
showing the menu. Without this deferred presentation mechanism, the
context menu can be presented before the state update, partially
obscuring the webview and resulting in an incorrect zoom once the
update occurs.

If a menu is already presented, use updateVisibleMenuWithBlock: to
update the contents of the menu.

(WebKit::WebPage::requestImageExtraction):

Refactor this code, such that the data structure that (weakly) holds elements pending image extraction is
distinct from the set of elements that have completed image extraction. This allows us to queue completion
handlers to each element with a pending image extraction request, and invoke them once image extraction is
finished.

The existing weak set, m_elementsWithExtractedImages, is now repurposed to keep track of only elements that
have finished image extraction (and may or may not contain an image overlay). The new member variable,
m_elementsPendingImageExtraction, maintains pairs of weak elements and completion handlers; upon finishing
image extraction, each completion handler corresponding to the element (if it still exists) will be invoked.
Since the element is weakly held, in the case where the element is destroyed before image extraction finishes,
we will clean up the (now-null) entries in m_elementsPendingImageExtraction when the image extraction request
is finished.

It is possible in theory for those synchronous injected bundle calls to mess with the frame tree and cause

In engineering builds, the Web Inspector is loaded as hundreds of separate resources instead of the handful of
minified sources used for released builds. When two Web Inspector windows are opened their loads can overlap
and it is possible for the sum total of file load operations to exceed the dispatch soft thread limit. To
resolve this, we set a sensible limit to the number of simultaneous inspector loading operations. A higher
number of allowed concurrent operations yielded no noticeable increase in load speeds.

This patch fixes the broken CPU instrument when viewing a JSON timeline recordng.

This exception is thrown when viewing a timeline recording that has been
imported from JSON file. Aside from the exception, the code is functionally
broken in this situation since passing a negative number to Array() doesn't work.

I tested this change manually and selection ranges now behave as expected, and
have not regressed in other instruments / UI.

UserInterface/Views/CPUTimelineView.js: Based on my investigation, the visibleEndTime is incorrectly computed when showing a JSON timeline recording because the currentTime property is always '0'. If this is the case, then let's assume that the entire range should be displayed.

Object allocation sinking phase should prioritize materializations with no dependencies before materializations with no reverse dependencies

Reviewed by Yusuke Suzuki.

JSTests:

stress/allocation-sinking-scope-materialization-order.js: Added. (var3.var2.x): (var3):

Source/JavaScriptCore:

Suppose we have two scope objects, A and B. Let's say A points to B, so B is
A's parent scope. A then depends on B. B has no dependencies here. When deciding
an order to materialize scope objects, we should always do it in reverse dependency
order. So above, we should materialize B, then A.

Inside object allocation sinking phase, when at an object materialization
site, we do track both dependencies and reverse dependencies. In the above
object graph, we'd attempt to materialize the objects in the right order,
always picking things with no dependencies first (and updating the list of
dependencies as we materialzed objects).

The code was using an std::list to track things to materialize, and it had
notions for materializing something first, and materializing something last.
However, there was a bug in how the code managed to insert things when
it first inserted last followed by inserting first. This patch simplifies
the code and makes it do the right thing.

<rdar://75351029>

Reviewed by Darin Adler.

No new tests; a truly deterministic test would require a .cgi script to block loading after
the WebM init segment, but a bug in the platform format reader causes URLs not ending in
.webm to fail to load the format reader plugin. Once this issue is fixed, we can write a
test to cover this behavior.

The WebM TrackEntry "enabled" bit is optional, and WebKit previously waited until any media data
was appended to say whether or not the track is enabled in the absense of an explicit signal.
Instead, assume any track that is not explicity disabled is enabled, for the purpose of the
format reader. This means that "enabled" queries will no longer block, which breaks the deadlock
when tearing down the AVAsset backing the WebM file.

"precustomized" state of custom elements can become HTMLUnknownElement
https://bugs.webkit.org/show_bug.cgi?id=221652

Reviewed by Darin Adler.

The bug was caused by createJSHTMLWrapper in JSHTMLElementWrapperFactory.cpp relying on
!isCustomElementUpgradeCandidate() to create HTMLUnknownElement as JS wrapper of the element.

This is problematic after r266269 since that change re-purposes CustomElementState::Failed
on a custom element as "precustomized" state instead of introducing another enum value in
CustomElementState as RareDataBitFields has no more bits available.

This patch fixes the problem by introducing a new NodeFlag::IsUnknownElement and using that
to check whether JSHTMLUnknownElement should be created for a given element or not. Note that

The Styleable returned by targetStyleable() holds a reference to the Element that at
this point is m_target (assuming it's non-null). However, once we set the new value
for m_target, if the only reference to the original target was held by this KeyframeEffect,
then that element will be deallocated and by the time we call didChangeTargetStyleable()
it will be gone.

To address, we create a RefPtr<Element> in the scope of KeyframeEffect::setTarget()
protecting the Styleable's element while didChangeTargetStyleable() is called.

Remove incorrect validation that IOSurface pixel format matches
the pixel format of the texture image being specified.

The "Element" in IOSurface is a block of pixels, while the validation assumed
it means one pixel. The validation failed for a compressed format.

Currently we map non-public YUV formats, to which there is no elequent way
of implementing the validation.
Most likely this started to reproduce if IOSurfaceGetBytesPerElementOfPlane
was changed to produce correct results for the above YUV format.

Later commits could add the validation back for formats that we know the
pixel format type.

Add a null check for the hit test result's targetNode inside rangeForPointInRootViewCoordinates() to avoid
crashing in the case where the target node is null and either result <= selectionStart is false or
selectionEnd <= result is false.

Additionally, avoid a potential null deref on selectionStart.deepEquivalent().anchorNode() and
selectionEnd.deepEquivalent().anchorNode() by using Position::treeScope() (which null checks the anchor
node) instead of directly asking the anchor node.

Note that the call sites of rangeForPointInRootViewCoordinates() already handle a WTF::nullopt return value
gracefully, by skipping the selection update.

Reviewed by Ryosuke Niwa.

When a radio button input element is removed from a form (either because it's moved or because the form
is deleted) then it's also removed from its current RadioButtonGroup. The latter removal might require the
update of the input validity status. In case of validity status changes, then we have to walk up
the ancestor chain in order to update the style for pseudo classes such as :valid :invalid. That node traversal
should not be done in case of being detached from the main document because our ancestors might have been
deleted before.

Apart from that we're replacing the HashSet of raw pointers to descendants in HTMLFieldSetElement by a WeakHashSet
which is safer.

REGRESSION(r273541) WKWebView can't load NSURLRequest subclasses
https://bugs.webkit.org/show_bug.cgi?id=224338
Source/WebCore:

<rdar://76192721>

Patch by Alex Christensen <achristensen@webkit.org> on 2021-04-08
Reviewed by Brent Fulgham.

We used to use SPI to extract the CFURLRequestRef, but now we just call encodeWithCoder and initWithCoder.
That's great for many reasons, but to stay binary compatible we have to continue to support NSURLRequest subclasses.
They fail in two possible ways:

In ObjC, you can do wild and crazy things such as overriding encodeWithCoder and not calling [super encodeWithCoder:coder];
The process decoding the request (one of our auxiliary processes) almost certainly has not linked with the definition of the subclass. This makes us receive an NSException like this when calling decodeObjectOfClasses:forKey:

* -[NSKeyedUnarchiver decodeObjectForKey:]: cannot decode object of class (TestURLRequest) for key (root) because no class named "TestURLRequest" was found;
the class needs to be defined in source code or linked in from a library (ensure the class is part of the correct target).
If the class was renamed, use setClassName:forClass: to add a class translation mapping to NSKeyedUnarchiver

To solve this problem, when attempting to encode a request that is not an NSURLRequest or NSMutableURLRequest, use existing code in ResourceRequest to extract
the parts we use into an NSMutableURLRequest that we can successfully decode.

OfflineAudioContext objects are leaking
https://bugs.webkit.org/show_bug.cgi?id=224279

Reviewed by Darin Adler.

Source/WebCore:

OfflineAudioContext objects were always leaking due to 2 reference cycles:

BaseAudioContext -> m_listener (AudioListener) -> m_positionX (AudioParam) -> m_context (BaseAudioContext)
BaseAudioContext -> m_destinationNode (AudioDestinationNode) -> m_context (BaseAudioContext)

For reference cycle 1, I made AudioSummingJunction (base class of AudioParam) hold a weak pointer to the
AudioContext instead of a Ref<>. I don't think there is a good reason for an AudioSummingJunction (AudioParam
or AudioNodeInput) to keep its AudioContext alive. AudioNodes already keep their AudioContext alive.
AudioNodeInputs and AudioParams are associated to AudioNodes.

For reference cycle 2, I made AudioDestinationNode not hold a strong pointer to its context but instead a
weak pointer. Since keeping an AudioDestinationNode alive should keep its AudioContext alive, I made it so
that ref'ing the AudioDestinationNode refs its BaseAudioContext. Also, BaseAudioContext::m_destinationNode
is now a UniqueRef<> instead of a RefPtr<> to avoid a cycle.

[JSC] DUCET level-1 weighs are equal if characters are alphabets
https://bugs.webkit.org/show_bug.cgi?id=224047

Reviewed by Saam Barati and Mark Lam.

JSTests:

stress/ducet-level-3-or-4-comparison.js: Added.

(shouldBe):

Source/JavaScriptCore:

ASCII comparison optimization was based on that DUCET level-1 weights are all different (except for 0000 case), but this was wrong.
If we have the same latin letters with different capitalization, then they have the same level-1 weight ('A' v.s. 'a').
In this patch,

If we found that the result of level-1 weight comparison is equal, and characters are not equal, then we do level-3 weight comparison. We do not perform level-2 since they are all the same weight in ASCII (excluding control characters) region.
We do not perform level-4 weight comparison since level-1 and level-3 comparison must distinguish the strings. Level-1 weights are equal only when characters are the same latin letters. And level-3 weight puts different weights for capital latin letters. Since we already know that these strings are different while they are equal in level-1 weight comparison, the only case is that they have same latin letters in the same position. In that case, level-3 weight must say different results for these characters so that we never meet "equal" status in level-3 weight comparison if characters are different.

Use Hasher more, remove IntegerHasher, fix hashing-related mistakes
https://bugs.webkit.org/show_bug.cgi?id=224138

Reviewed by Chris Dumez.

Source/JavaScriptCore:

bytecode/BytecodeIndex.h:

(JSC::BytecodeIndex::hash const): Remove unneeded WTF prefix on call
to intHash.

ftl/FTLAbstractHeap.h: Use HashTraits instead of WTF::GenericHashTraits.

ftl/FTLLowerDFGToB3.cpp:

(JSC::FTL::DFG::LowerDFGToB3::validateAIState): Remove unneeded WTF
prefix on call to intHash.

wasm/WasmLLIntGenerator.cpp: Use HashTraits instead of WTF::GenericHashTraits.

Source/WebCore:

contentextensions/ContentExtensionRule.h:

(WebCore::ContentExtensions::TriggerHash::hash): Use computeHash to
hash all the fields instead of a custom-written algorithm. The custom
algorithm had some magic numbers, repeatedly hashed hashes, and combined
hashes using exclusive or. The new one is almost certainly better.

contentextensions/Term.h:

(WebCore::ContentExtensions::Term::CharacterSet::hash const):
Use computeHash to hash the boolean and the characters rather than
using intHash and pairIntHash.

css/parser/CSSParserContext.cpp:

(WebCore::add): Moved the hashing here from the header. Fixed the
mistake where this was using & instead of | and so none of the booleans
were having any effect on the hash value.

css/parser/CSSParserContext.h: Use WTF_MAKE_STRUCT_FAST_ALLOCATED so

we don't have to say public: explicitly. Also moved all the function
members to the bottom of the struct. This is typically preferred style
for structures as opposed to classes. Since the data members are the
primary interface, they are first, and all function members are secondary
and so they come after.
(WebCore::CSSParserContextHash::hash): Use convertHash instead of
a custom written hash function. The custom written function was combining
hahes using exclusive or, not a best practice, and also had a mistake
where it used & instead of | and so the "bits" local variable was always 0.

html/FormController.cpp: Use HashTraits instead of WTF::GenericHashTraits.

platform/encryptedmedia/CDMProxy.h: Removed unneedes includes.

platform/graphics/Font.cpp: Changed CharacterFallbackMapKey into a

simple struct with no additional function members or static data members.
Changed CharacterFallbackMapKeyHash to use computeHash to calculate the
hash, instead of IntegerHasher. Probably better to hash the pointer of
the AtomString rather than hashing the hash, but either way, we should
have the best implementation for AtomString hashing in the Hasher class.
Added CharacterFallbackMapKeyHashTraits instead of using
SimpleClassHashTraits. Use the value U_SENTINEL for the UChar32 character,
which is the same as the -1 used before, but slightly clearer why it's OK.
(WebCore::Font::systemFallbackFontForCharacter const): Use HashMap::ensure
instead of HashMap::add to make the logic simpler.

platform/graphics/Font.h: Use bool instead of uint8_t as the base type

for the No/Yes enumeration IsForPlatformFont.

platform/graphics/FontCache.cpp: Removed unneeded "using namespace WTF",

which is not our best practice, especially given unified builds.
Changed FontPlatformDataCacheKey into a simple struct, removing all the
hash-related member functions. Also used struct-style naming for the
members without an "m_" prefix. Used the type FontFamilyName for the
family name, which means we will use FontCascadeDescription's system
for hashing and comparing family names for equality without having to
remember do to so explicitly. Changed FontPlatformDataCacheKeyHash to
use computeHash. The old version had unnecessarily complex logic to
handle Optional and was unnecessarily hashing hashes.
(WebCore::FontCache::cachedFontPlatformData): Renamed to remove "get"
from the function's name. Also use shorter argument and local variable
names that are single words, and updated since FontPlatformDataCacheKey
is now a struct without a constructor.
(WebCore::FontCache::fontForFamily): Use shorter names.
(WebCore::operator==): To compare two FontCascadeCacheKey objects,
use a simpler constructions, depending on the fact that Vector already
has an == operator and we are using FontFamilyName for the elements
of the vector, which has a correct == operator.
(WebCore::FontCascadeCacheKeyHash::hash): Use computeHash since
the FontFamilyName hashing is now correct, and we can rely on the
way Hasher knows how to iterate a collection.
(WebCore::FontCache::retrieveOrAddCachedFonts): Update since
FontCascadeCacheEntry is now a simple struct. Also use constexpr a bit.
(WebCore::FontCache::invalidate): Use copyToVectorOf<> to simplify the
code that calls fontCacheInvalidated on all the font selectors.

platform/graphics/FontCache.h: Use "using" instead of "typedef".

Remove FontDescriptionKey::computeHash.
(WebCore::add): An overload of add for Hasher to include a
FontDescriptionKey in a hash, which just lists all the data members.
The old version did a hash of hashes, but that's not needed any more.
Updated FontDescriptionKeyHash to use the Hasher version of ComputeHash.
Added FontFamilyName. Change FontCascadeCacheKey to use a vector of
FontFamilyName instead of AtomString. In FontCascadeCacheEntry, use
WTF_MAKE_STRUCT_FAST_ALLOCATED instead of WTF_MAKE_FAST_ALLOCATED
and also got rid of the unneeeded constructor.
(WebCore::FontCascadeCacheKeyHashTraits::constructDeletedValue):
Use the deleted value of FontDescriptionKey.
(WebCore::FontCascadeCacheKeyHashTraits::isDeletedValue): Ditto.
Renamed getCachedFontPlatformData to just cachedFontPlatformData.

platform/graphics/FontGenericFamilies.h: Use HashTraits instead of

WTF::GenericHashTraits.

platform/graphics/FontSelectionAlgorithm.h:

(WebCore::FontSelectionRange::uniqueValue const): Deleted.
(WebCore::add): Add both the minimum and maximum values to the hash
separately instead of combining them. For now, this makes the way
they are hashed a bit inefficient, but that can be re-tightened up by
improving the algorithm of Hasher if we like. Should be fine for our
needs either way.

platform/graphics/FontTaggedSettings.cpp:

(WebCore::FontFeatureSettings::hash const): Deleted.
(WebCore::FontVariationSettings::hash const): Deleted.

platform/graphics/FontTaggedSettings.h: Added overloads of the

add(Hasher&) function for std::array<char, 4> and FontTaggedSetting<T>.
Got rid of many uses of pass by reference instead of value for FontTag,
since it fits into a 32-bit register and bth more source code and less
efficient to pass by value.

platform/graphics/Gradient.cpp: Removed "using WTF::pairIntHash" since

that's now done in the WTF header.

platform/graphics/cg/GraphicsContextCG.cpp: Ditto. Also removed

"using WTF::GenericHashTraits", which was unhelpful. The GenericHashTraits
template is only really needed when specializing HashTraits, which
already has to be done within the WTF namespace. In all other cases, we

instead of WTF::GenericHashTraits.

platform/graphics/cocoa/FontFamilySpecificationCoreText.cpp:

platform/graphics/cocoa/SystemFontDatabaseCoreText.h:

WTFMove on ObjectIdentifier, which are just integers, so move vs. copy

DefaultHash. Use computeHash to hash the contents of the vector instead of
hashing the hashes of the items in the vector. This is better in general and
better for the one case where we are currently using this, for a Vector<int>.
We want to hash all the integers rather than hashing hashes of all the integers.
In the future, this means the elements of the Vector need to be hashable using
the Hasher machinery. The old requirement was the the elements had a DefaultHash.

Rename and make the TerminationException a singleton.
https://bugs.webkit.org/show_bug.cgi?id=224295

Reviewed by Keith Miller.

Source/JavaScriptCore:

We previously call it the TerminatedExecutionException, which is a mouthful but
adds no meaningful information. It's now renamed to TerminationException.

We can make it a singleton because the TerminationException is just a VM internal
mechanism for implementing the termination of the current execution stack. It
should never be exposed to user JS code, and therefore, there is no value in
making it a JS object. Making it a singleton simplifies the code.

A TerminationException is now implemented as an Exception cell which holds a
Symbol with the name "TerminationError". The TerminationException is only created
if needed e.g. if the JSC watchdog is created, or if the VM is for a Worker thread
which needs to be able to handle termination requests.

We'll also stop notifying the debugger when we throw the TerminationException.
This is because the TerminationException is not like ordinary exceptions that
should be reported to the debugger. The fact that the TerminationException uses
the exception handling mechanism is just a VM internal implementation detail.
It is not meaningful to report it to the debugger as an exception.

Remove RepaintLayoutRectsMap
https://bugs.webkit.org/show_bug.cgi?id=224217

Reviewed by Zalan Bujtas.

RepaintLayoutRectsMap was a side table used to map RenderLayerModelObjects to
repaint rects for their corresponding layers. However, this HashMap could
get large, and waste more space than if we just stored the repaint rects
on RenderLayer.

For example, on twitter.com we could have about 2000 RenderLayers; increasing
their size by 32 bytes (the size of the two LayoutRects) adds 62KB, but RepaintLayoutRectsMap
would contain about 1950 entries with a capacity of 8192, wasting around 200KB.

So moving repaint rects into RenderLayer is a memory saving. This patch does so
without using Optional<> since that introduces extra padding.

[PlayStation] Do not include <any> in gtest because it requires RTTI
https://bugs.webkit.org/show_bug.cgi?id=224281

Reviewed by Ross Kirsling.

To determine platform capabilities gtest looks to see if a platform is using a minimum
C++ version and whether it has a required header. In the PlayStation's case it sees that
the <any> header is present with the requisite version of C++ so it defines support for it
and includes the header. However in the PlayStation's case to use <any> RTTI must be
enabled and if it isn't an error is generated.

This patch adds a way to short circuit GTEST_INTERNAL values for ports. An upstream fix is
in review at https://github.com/google/googletest/pull/3345 and if landed then the next
update to gtest can remove this patch.

[WPE][GTK] Null pointer dereference when child process exits immediately
https://bugs.webkit.org/show_bug.cgi?id=224209

Patch by Michael Catanzaro <Michael Catanzaro> on 2021-04-07
Reviewed by Carlos Garcia Campos.

We discovered that when the child process exits immediately after it is spawned,
g_subprocess_get_identifier() will return nullptr. In this case, we should crash cleanly
with SIGABRT via g_error(), rather than crashing with a null pointer dereference inside
g_ascii_strtoll(). SIGABRT is much nicer than SIGSEGV and indicates that we really do want
to crash here, whereas SIGSEGV is just a bug.

Also, let's be careful with our terminology in the existing error message here. Although
GSubprocess currently always forks, I'm working to make it use posix_spawn() instead, so
let's not claim that fork() has failed when it soon might not be used at all.

[EME][GStreamer] Abort decryptor operations immediately and without errors on flush
https://bugs.webkit.org/show_bug.cgi?id=223742

Reviewed by Xabier Rodriguez-Calvar.

A decryptor transformInPlace() operation can cause potentially long waits in
two situations:

transformInPlace() is waiting to get the cdmProxy.
The CDMProxy::decrypt() method is internally waiting for a specific key to become available.

If a seek operation is performed during those long waits, the main thread will
be blocked until the seek finishes the conditions those long waits are waiting
for will never be fulfilled (because the operations that complete them happen
in the main thread, which is blocked), the internal wait timeouts will trigger
and the decoder will trigger an unrecoverable error.

The solution for this is to break the waits by issuing the right notifications,
and to detect the flushes performed by the seek, distinguising this special
"abort" case from a regular error, so that the situation is no longer
unrecoverable.

This solution involves changes in several layers. A public
CDMProxy::abortWaitingForKey() method is exposed to allow the decryptor to
awake the inner waitFor() that checks for the key. The cdmProxy wait is also
awaken in case there's no cdmProxy available yet.

In order to distinguish if the awakenings are caused by real errors (no
cdmProxy, no key available) or by a flush operation (caused by the seek), the
decryptor first needs to keep track of the "flushing" state and allow other
objects to know about it. CDMProxy is one of those objects, but due to layer
limitations it can't directly ask about it to the decryptor (it can't "see"
it).

A new CDMProxyDecryptionClient interface is created, and the decryptor will
hold an implementation of it (as CDMProxyDecryptorClientImplementation).
CDMProxy can then know the client isAborting(), and the client will know the
decryptor and will ask about it.

As the pipeline, and thus the decryptor, can be destroyed at any moment,
the client holds a WeakPtr to the decryptor and will only ask if isAborting()
if the pointer is still alive.

Fix Wasm::MemoryHandle::boundsCheckingSize. We should just return m_mappedCapacity here since UINT32_MAX is not 4GB. This checking size can include redzone for fast-memory, but this is OK: bounds-check pass in LLInt (in upper tiers, we do not use bounds-check for fast-memory), and access to redzone, then fault occurs and signal handler can make it error since signal handler is checking whether the access is within Memory::fastMappedBytes which includes redzone.
Fix caging of wasm memory-base pointer in LLInt. We should use pointer sized length since it can be larger than 4GB. And we should handle nullptr case correctly: Wasm::MemoryHandle's memory can be nullptr when mapped size is zero. caging needs to handle this case as we do in CagedPtr::getMayBeNull.

[GStreamer] Only seek to change the rate un updatePlaybackRate() when needed
https://bugs.webkit.org/show_bug.cgi?id=224235

Reviewed by Alicia Boya Garcia.

A seek is used by MediaPlayerPrivateGStreamer to update the playback
rate used in the pipeline. There's a special case when the rate is 0.0.
This actually means "paused" and, when set, the pipeline is changed to
PAUSED and no updatePlaybackRate() call is made because of an early
return (and therefore, no seek). When the rate is restored to a
non-zero value, the pipeline is set again to PLAYING, but a
call to updatePlaybackRate() is done, which implies an unconditional
seek.

It should be possible to do the seek in updatePlaybackRate() only if the
rate changed with respect to the original one, instead of always doing
it. This would avoid unneeded seeks, which are complex operations that
can trigger collateral issues such as the one addressed in
https://bugs.webkit.org/show_bug.cgi?id=223742.
