Render tree updates for Text node content mutations should happen during rendering update
​https://bugs.webkit.org/show_bug.cgi?id=222406
<rdar://problem/74822830>

Reviewed by Simon Fraser.

Source/WebCore:

Calls to Text.insertData and similar should not mutate render tree synchronously.
Instead render tree should be updated during the next rendering update along with
any style changes.

These updates already go via RenderTreeUpdater. We just need to save the information
about which nodes need updating so the next rendering update can pick them up.

This seems to help with some performance benchmarks.

REGRESSION (r276189): GPUProcess.WebProcessTerminationAfterTooManyGPUProcessCrashes is crashing
​https://bugs.webkit.org/show_bug.cgi?id=224790
<rdar://problem/76869318>

Reviewed by Darin Adler.

Source/WebKit:

GPUProcess.WebProcessTerminationAfterTooManyGPUProcessCrashes is intentionally repeatedly
killing the GPUProcess. As a result, the GPUProcess may get killed very shortly after
a relaunch and the RemoteAudioDestinationManager::StartAudioDestination synchronous IPC
may fail if it is ongoing at the time of the crash. This would cause m_destinationID to
not get initialized and then get sent as IPC parameter, thus crashing.

pre-r276189, we were not crashing because m_destinationID was not reset on crash and we
would thus send IPC for a destination that does not exist but at least the destinationID
would not be 0. This patch makes sure we don't try and send IPC at all when m_destinationID
is 0.

Reviewed by Devin Rousso.

The Styles panel will not always be part of the same sidebar as the Computed panel as of r268691, so we should
look for the Styles panel in WI.detailsSidebar, which will report all of the panels it manages across multiple
sidebars. Additionally, as of r270134, there is no longer a private _visible property for
WI.StyleDetailsPanel, so it can not be used by WI.SpreadsheetRulesStyleDetailsPanel. Instead, visibility
should be determined by checking if the panel is attached and not pending layout.

Rename FloatQuad::isEmpty() to boundingBoxIsEmpty() and reimplement isEmpty()
​https://bugs.webkit.org/show_bug.cgi?id=224769

Reviewed by Tim Horton.

Source/WebCore:

The existing isEmpty() method on FloatQuad only checks that the bounding box of the quad is empty (as
indicated by the comment above the method declaration). This means isEmpty() returns false in cases where
the quad consists of one or more non-rectilinear line segments, even though the quad contains no area.

To address this, we rename the existing isEmpty() helper to boundingBoxIsEmpty() and reintroduce an
isEmpty() method that accounts for quads which are equivalent to non-rectilinear line segments.

No change in behavior.

Web Inspector: Grid overlay column line label placement copy/paste error
​https://bugs.webkit.org/show_bug.cgi?id=224777

Reviewed by Devin Rousso.

In grid overlays, a typo meant for all column line labels after the initial line, only the start of the line was
used for placement, where it is more accurate to use the start and end points to match the behavior of the first
line. This had no visual impact because subsequent lines do not currently have their labels adjusted further into
the grid, only flipped into the grid but still referencing the same point. This patch corrects the value of
gapLabelLine to always be a line on which the label can be placed, instead of a single point.

MotionMark's Canvas-Arcs subtest is broken if the GPUProcess is not yet running
​https://bugs.webkit.org/show_bug.cgi?id=224778

Reviewed by Simon Fraser.

I recently made changes so that the GPUProcess is only launched when it is needed. This means
that until MotionMark's Canvas-Arcs subtest, the GPUProcess is usually not yet running. As a
result, RemoteRenderingBackendProxy::createImageBuffer() ends up launching the GPUProcess
and sending the GPUConnectionToWebProcess::CreateRenderingBackend and
RemoteRenderingBackend::CreateImageBuffer IPC right away. We seem to have a synchronization
issue because when this happens, the rendering for the Canvas-Arcs subtest is visibly broken
and its score is very low (< 6, instead of > 600).

Making the GPUConnectionToWebProcess::CreateRenderingBackend synchronous again (I made it
async recently) seems to address the synchronization issue and restores correct behavior on
MotionMark. I am therefore making this IPC synchronous again in this patch to get benchmark
coverage again while I investigate the root cause offline.

Source/WebCore:

LineCandidate.inlineContent is a set of candidate runs for the line and when the line breaker says "please revert" (move back to an earlier position on the line)
these runs should all be ignored as they did not make it to the line.

[bmalloc] Enable Adaptive Scavenger for Mac
​https://bugs.webkit.org/show_bug.cgi?id=224706

Reviewed by Filip Pizlo.

Enabled the adaptive scavenger code paths for macOS.
The original reason that the partial scavenging paths were kept for macOS was due
to regression on power tests. To alleviate the power regression, this patch splits
out the adaptive scavenger parameters with macOS specific values.

The parameters are:

The multiplier used to compute the next scavenging wait time based on the

time needed for the prior scavenging.

Minimum wait time between scavenging.
Maximum wait time between scavenging.

The values in the current code are:

Wait time Multiplier: 150
Minimum wait time: 100ms
Maximum wait time: 10,000ms (10 seconds)

The proposed values for macOS, determined using empirical testing.

Wait time Multiplier: 300
Minimum wait time: 750ms
Maximum wait time: 20,000ms (20 seconds)

When tested on various mac variants, this change:

• Provides a 3-5% reduction in memory use on RAMification.
• It is neutral on JetStream2.
• It is neutral to a slight regression on Speedometer2, but there is some variability in those results.

Since macOS was the only platform still using the partial scavenging code path,
the partial scavenging code paths were deleted.

Fix races in LibWebRTCCodecs introduced in r276214
​https://bugs.webkit.org/show_bug.cgi?id=224758

Reviewed by Youenn Fablet.

After r276214, LibWebRTCCodecs's createDecoder() / createEncoder() may hop to the main
thread to initialize the connection to the GPUProcess. If releaseDecoder() / releaseEncoder()
were to get called very shortly after, they may win the race and have no decoder / encoder
to release, since they are dispatched directly to the background thread. To address the issue,
we now call ensureGPUProcessConnectionAndDispatchToThread() in releaseDecoder(), releaseEncoder()
and initializeEncoder().

Implement rudimentary support for clang thread safety analysis.
The added macros can be used to declare which member variables or

• wtf/CheckedLock.h: Added.

Add CheckedLock, a Lock variant that is amenable to static
analysis.
Add a Locker specialization for CheckedLock that is amenable to
static analysis.

Locker<CheckedLock> is a std::scoped_lock. The scoped_lock cannot be aliased,
since it appears that (Apple's) libcxx is not compiled with thread safety
analysis support enabled by default.

New types are needed due Locker move constructor and conditional locking.
The Locker has default usage pattern of:

auto locker = holdLock(m_lock);

This forces dynamism that removes the possibility of simple statical
analysis that thread safety analysis capabilities "mutex" and "scoped_lock"
currently implement. Most likely large fraction of call sites is due to historical
lack of CTAD and as such can be converted to less general form.
Once the pattern is not used by default, CheckedLock can be deleted
and the move dynamism bits of Locker can be moved to some more specific type
("UncheckedLocker").

Instead of allocating the buffer on valid data, we wait for data to be of the correct sample rate.
We preallocate the buffer accordingly in constructor to avoid allocation in the webrtc audio thread.

Reduce crackling at start of playing a live audio track
​https://bugs.webkit.org/show_bug.cgi?id=218898
<rdar://problem/71625010>

Reviewed by Eric Carlson.

We often hear crackles at the beginning of playing a MediaStreamTrack.
This is due to starting at a point where there is not enough data, so we start rendering and quickly run short of data.
Our heuristic to start was not good since we were not accounting to LibWebRTC audio module which sends audio samples by batch of 5 samples.
So we would have needed to at least have 6 samples to be sure to not run out of data.

What this patch does:

• Add an extra parameter to AudioSampleDataSource so that we do not start until we have at least been pushed a given number of sample count.
• Change LibWebRTAudioModule to send audio samples by batch of 3 (hence 30 ms) instead of 5
• Set this new parameter to 2 for local tracks and 4 for remote tracks
• Add a new boolean to AudioSampleDataSource to know whether we start the track for the first time or not. If we start it, use the new parameter to buffer enough data. Otherwise, use current heuristic.

We also reduce the AudioSampleDataSource buffer to 0.5 seconds instead of 2 seconds, since 2 seconds is too much for real time audio.

Manually tested.

Patch by Felipe Erias <Felipe Erias> on 2021-04-19

Source/WebCore:

Update table layout to take into account the overriding height set by the element's parent.
This was causing several WPT tests to fail.

• rendering/RenderTable.cpp:

(WebCore::RenderTable::layout):
During layout, set the computed height so that it is at least as large as the overriding height

This additional height will be distributed among the table's sections so its total height matches
the overriding value.

[css-scroll-snap] Properly support fractional scroll steps in WebCore::ScrollAnimator::scroll
​https://bugs.webkit.org/show_bug.cgi?id=224176

Reviewed by Simon Fraser.

Stop using the ScrollableArea's position to calculate scroll snap positions in ScrollAnimator::snap.
The position stored in ScrollAnimator is a floating point position, while the one stored in ScrollableArea
is an integer position. This currently isn't an issue, because all callers of ScrollAnimator::scroll
use integer scroll offsets, but this will allow this function to be used in the future for precise
scrolling delta.

No new tests. This doesn't change any behavior, since all callers currently use
integer scroll offsets, but a future change will make use of this fix.

(WebCore::ScrollAnimator::scroll): Get the current scroll position from the ScrollAnimator,
which stores it in floating point. Also, only call into the scroll snap code if we actually
have scroll offsets.

This patch implements layout containment as specified[1].

containing block is established.

• a stacking context is created.

[JSC] Do not use Bag<> for DFG / FTL watchpoints
​https://bugs.webkit.org/show_bug.cgi?id=224715

Reviewed by Darin Adler.

While Bag<> is useful since its allocated memory will not be moved,
this is really memory-inefficient data structure. Each entry gets a
tail pointer (so adding 8 bytes) and we allocate each entry separately.

In DFG and FTL, we are using Bag<> for watchpoints. But this is not necessary actually: thanks to
concurrent compilers, our watchpoint registration is batched at the end of compilation. This means
that we have a way to know how many watchpoints we should register at that point.

In this patch, we introduce WatchpointCollector. In DesiredGlobalProperties, we run reallyAdd twice
with WatchpointCollector. First time, we just count # of watchpoints. Then we allocate FixedVector<XXXWatchpoint>
and install them. Since we do not (cannot) grow this fixed vector, watchpoint's address will not be changed as required.

We also move DesiredGlobalProperties under DesiredWatchpoints since this basically registers watchpoints.

Use binary-search in LocaleToScriptMapping
​https://bugs.webkit.org/show_bug.cgi?id=224727

Reviewed by Darin Adler.

This patch removes HashMaps in LocaleToScriptMapping, and binary-search onto the constant data arrays.
These maps are not frequently used. Keys of the maps can be encoded into uint32_t or uint64_t so that
comparison becomes super cheap and we can initialize this array at compile-time.

We introduce ScriptName(uint32_t) and LocaleName(uint64_t) instead of String. And ues it and generate
sorted constant data array for mappings. We use binary-search to look entry up. Since # of entries are
not huge (~200), comparisons are extremely cheap (uint32_t / uint64_t comparison), and this is not a
hot code, we can just use binary-search here and eliminate HashMaps' memory allocation.

[JSC] Make more DFG/FTL data FixedVector/Vector

Reviewed by Darin Adler.

1. DFG::JITCode::m_osrEntry / DFG::JITCode::m_osrExit / DFG::JITCode::m_speculationRecovery are changed to FixedVector. They are added at compiling time, and after that, these vectors are not modified. So when finalizing, we can easily make it FixedVector. We also change OSREntry::{m_reshufflings,m_expectedValues} to FixedVector and FixedOperands.
2. FTL::JITCode::m_osrExit is changed from SegmentedVector to Vector. We are still using Vector since it also involves osrExitDescriptor. But later, we should merge m_osrExit to osrExitDescriptor. Vector is still better than SegmentedVector since it wastes several entries per segment. SegmentedVector was used to use a direct pointer of OSRExit (this is not possible in Vector since this pointer can be invalidated after growing), but usage of that is fairly limited so that we can just replace them with m_index + osrExit vector.

The blobURL member of PromisedAttachmentInfo was originally introduced to facilitate drag and drop support
for attachment elements in WebKit2, by writing blob URL data to temporary file paths on behalf of
NSFilePromiseProvider when starting a drag on attachment elements backed by blobs. However, this was
superceded by use of NSFileWrapper and the _WKAttachment SPI instead, such that we only support dragging
attachment elements if they correspond to API Attachment objects in the UI process. This means we can remove
this blobURL, along with the file name and content type members of the struct (which were only added to
support the ability to drag blob-backed attachments).

Code that utilized this member was originally introduced in <​https://trac.webkit.org/r235202>, and was
subsequently removed in <​https://trac.webkit.org/r240687>.

LibWebRTCCodecs eagerly launches the GPUProcess and always relaunches it on exit
​https://bugs.webkit.org/show_bug.cgi?id=224704

Reviewed by Darin Adler.

LibWebRTCCodecs eagerly launches the GPUProcess and always relaunches it on exit. The GPUProcess
should only be (re-)launched when needed. In the case of the LibWebRTCCodecs, it seems it only
needs a GPUProcess connection if it has m_decoders / m_encoders are non-empty.

• WebProcess/GPU/webrtc/LibWebRTCCodecs.cpp:

(WebKit::LibWebRTCCodecs::ensureGPUProcessConnectionOnMainThread):
Renamed startListeningForIPC() to ensureGPUProcessConnectionOnMainThread(). Only do the
connection initialization if m_connection is not null.

(WebKit::LibWebRTCCodecs::ensureGPUProcessConnectionAndDispatchToThread):
Version of dispatchToThread() which makes sure that the GPUProcessConnection is initialized
before dispatching. It is used when constructing a decoder / encoder. It sets the
m_needsGPUProcessConnection flag to true to indicate someone needed the connection
(and that we should re-initiate it in case it is severed). If the connection is already
initialized, then it does a simple dispatchToThread(). If the connection is not initialized
yet, then we have to hop to the main thread (if not already on it) to initialize the
GPUProcessConnection.

(WebKit::LibWebRTCCodecs::gpuProcessConnectionMayNoLongerBeNeeded):
Function that gets called on the background thread every time a encoder / decoder is
removed. Its purpose is to set m_needsGPUProcessConnection back to false once we no
longer have any encoder / decoder, so that gpuProcessConnectionDidClose() does not
attempt to relaunch the GPUProcess if it goes away.

LibWebRTCCodecs::setCallbacks():
Check if VP9Support is enabled via PlatformMediaSessionManager instead of from the
GPUProcessConnection. This avoids eagerly launching the GPUProcess. The
GPUProcessConnection constructor gets its VPx support information from
PlatformMediaSessionManager anyway. The WebPage constructor is where the VPx support
information comes from and it updates the VPx flags on the PlatformMediaSessionManager.
The WebPage constructor only updates the VPx flags on the GPUProcessConnection if this
connection already exists to avoid eagerly launching the GPUProcess.

(WebKit::LibWebRTCCodecs::createDecoder):

• Call ensureGPUProcessConnectionAndDispatchToThread() instead of dispatchToThread() to make sure we have a GPUProcessConnection before creating the decoder.
• Add a missing locker for m_connectionLock on the background thread since it is using m_connection (pre-existing bug).

(WebKit::LibWebRTCCodecs::releaseDecoder):
Call gpuProcessConnectionMayNoLongerBeNeeded() to reset the m_needsGPUProcessConnection
flag to false if necessary.

(WebKit::LibWebRTCCodecs::createEncoder):

• Call ensureGPUProcessConnectionAndDispatchToThread() instead of dispatchToThread() to make sure we have a GPUProcessConnection before creating the encoder.

(WebKit::LibWebRTCCodecs::releaseEncoder):
Call gpuProcessConnectionMayNoLongerBeNeeded() to reset the m_needsGPUProcessConnection
flag to false if necessary.

(WebKit::LibWebRTCCodecs::gpuProcessConnectionDidClose):

• Clear m_connection when the GPUProcess connection is severed (note that this does not necessarily indicate a crash since the GPUProcess exits when idle and under memory pressure).
• Only re-initiate the GPUProcess connection if m_needsGPUProcessConnection is true, meaning that we have encoders/decoders. I use this flag instead of checking m_encoders & m_decoders since those containers are modified on the background thread and this function is called on the main thread.

• WebProcess/GPU/webrtc/LibWebRTCCodecs.h:

(WebKit::LibWebRTCCodecs::create):

• Stop calling startListeningForIPC() on construction as we don't want to launch the GPUProcess

until an encoder / decoder is created.

• Fix a pre-existing issue where the class subclasses ThreadSafeRefCounted (via ThreadMessageReceiverRefCounted) and yet was using std::unique_ptr<> instead of RefPtr<>.

RemoteImageDecoderAVFManager should never re-launch the GPUProcess on destruction
​https://bugs.webkit.org/show_bug.cgi?id=224723

Reviewed by Darin Adler.

RemoteImageDecoderAVFManager was calling ensureGPUProcessConnection() it is destructor,
just to remove itself as an IPC message receiver. This means it could unnecessarily
relaunch the GPUProcess. This patch addresses that.

This patch also makes it so that RemoteImageDecoderAVFManager registers itself as a
client of the GPUProcessConnection, so that it gets notified when the connection gets
severed. Right now, I only do very basic crash handling but this paves the way to do
better in the future. I did fix a bug where the RemoteImageDecoderAVFManager would
not re-register itself as a message receiver after a GPUProcess re-launch.

[GStreamer][MediaStream] fast/mediastream/play-newly-added-audio-track.html is failing since added in r260380
​https://bugs.webkit.org/show_bug.cgi?id=210840

Reviewed by Xabier Rodriguez-Calvar.

Source/WebCore:

The test was failing mainly because our mediastreamsrc GStreamer element wasn't creating the
corresponding AudioTrackPrivateMediaStream object. The media player should propagate its
volume/mute/is-playing states to the source element. And also until now our mediastreamsrc
element was handling at most one audio track and at most one audio track, but it turns out
multiple audio tracks can be added actually. So I refactored the element internals
accordingly. The InternalSource is now directly observing the corresponding
RealtimeMediaSource, which simplified some code. Observing is also now suspended/resumed
depending on the element state.

We don't implement a GStreamer AudioMediaStreamTrackRenderer class yet, because actual
rendering is still performed from the WebProcess, so early returns were added in
AudioTrackPrivateMediaStream to handle this case.

Perform port blocking earlier in the load
​https://bugs.webkit.org/show_bug.cgi?id=224525
<rdar://problem/75440591>

Reviewed by Darin Adler.

Source/WebCore:

WebKit blocks loads to URLs with any of the prohibited ports defined in

early, at the same time we perform other checks.

Note: The fact that we now block loads earlier means that we do not fire
'willSendRequestForFrame' for blocked ports, so WebKitTestRunner no longer
outputs a message to stdout. Those errors are reported in the JS console,
but since some test paths are specified to always output JS console messages
to stderrr (for example the WPT tests), we have to revise out test expectations
for a few cases.

[GPUProcess] Crash under RemoteAudioDestination::render()
​https://bugs.webkit.org/show_bug.cgi?id=224688
<rdar://76643365>

Reviewed by Eric Carlson.

Source/WebKit:

When the connection between the GPUProcess and the WebProcess was severed,
GPUConnectionToWebProcess::didClose() would get called and end up destroying
the RemoteAudioDestination object on the main thread. The issue is that the
RemoteAudioDestination may be playing at the time and we would end up
destroying the RemoteAudioDestination object without stopping rendering
first. As a result, we would crash on the background thread in the
RemoteAudioDestination::render() function, trying to use the m_ringBuffer
data member that got destroyed on the main thread.

To address this, I updated the RemoteAudioDestination destructor so that it
stops rendering if necessary. AudioOutputUnitStop() is synchronous so this
ensures render() is done running on the background thread (and won't be
called again) before proceeding with the destruction of the data members.

Test: webaudio/AudioContext/audiocontext-destruction-crash.html

• GPUProcess/media/RemoteAudioDestinationManager.cpp:

Updated the class to stop subclassing ThreadSafeRefCounted. This class does
not need RefCounting at all. I updated the call site to use UniqueRef<>.

(WebKit::RemoteAudioDestination::create): Deleted.
Drop this factory function and made the constructor public now that we no longer
subclass ThreadSafeRefCounted and use makeUniqueRef<>() at the call site.

(WebKit::RemoteAudioDestination::scheduleGracefulShutdownIfNeeded): Deleted.
Stop this function now that the destructor takes care of shutting down gracefully.

(WebKit::RemoteAudioDestination::RemoteAudioDestination):
Made the constructor public.

(WebKit::RemoteAudioDestination::render):

• Stop checking m_protectThisDuringGracefulShutdown on the background thread. This data member is not needed since stop() is synchronous. It was also not thread-safe since m_protectThisDuringGracefulShutdown was set on the main thread and we are on the audio thread here.
• Similarly, drop the check for m_isPlaying. m_isPlaying is not atomic so the check was not thread safe. Even if m_isPlaying was atomic, m_isPlaying get set to true *after* calling m_audioOutputUnitAdaptor.start() so render() may early return even though we were playing. Also, this check is not needed since we set m_isPlaying to false after calling m_audioOutputUnitAdaptor.stop() and the stop() call is synchronous and should not return until the audio thread stopped rendering.

font-size with viewport units in calc() doesn't change when viewport resizes

Reviewed by Zalan Bujtas.

Source/WebCore:

• css/CSSToLengthConversionData.cpp:

(WebCore::CSSToLengthConversionData::zoom const): Updated since m_zoom is now optional.
We use effectiveZoom when m_zoom is not specified, which is the same semantic that was
implemented before with a separate boolean.
(WebCore::CSSToLengthConversionData::viewportWidthFactor const): When calling the
setHasViewportUnits function as a side effect, use m_viewportDependencyDetectionStyle,
rather than always using m_style. This lets us handle the font-size case correctly.
Also removed the explicit computingFontSize check for the same reason.
(WebCore::CSSToLengthConversionData::viewportHeightFactor const): Ditto.
(WebCore::CSSToLengthConversionData::viewportMinFactor const): Ditto.
(WebCore::CSSToLengthConversionData::viewportMaxFactor const): Ditto.

• css/CSSToLengthConversionData.h: Added a new member, m_viewportDependencyDetectionStyle,

which defaults to the same value as m_style. Also changed m_zoom to use Optional instead
of a separate boolean and an ignored "must be 1.0" value. Initialized data members in
the modern way, allowing us to use the default constructor.

• style/StyleBuilderCustom.h:

(WebCore::Style::BuilderCustom::applyValueFontSize): Pass in the builder's style as the
viewportDependencyDetectionStyle. This does the same thing that the existing code to
call setHasViewportUnits did directly, but does it even for more complex cases involving
calc(). Also made the isLength and isCalculatedPercentageWithLength cases more similar
to each other and left a FIXME behind about taking that a bit further, but doing that
probably requires creating some more test cases.

Added tests that involve calc, and broke rules up into multiple elements so that side

Place vertical scrollbars at (inline/block)-end edge in all writing modes.

Tests: fast/scrolling/v-rl-scrollbars-initial-position-dynamic.html

fast/scrolling/v-rl-scrollbars-initial-position.html
fast/scrolling/vertical-scrollbar-position.html

We currently only consider moving a vertical scrollbar to the left for
writing-mode: horizontal-{tb,bt}; direction: rtl containers. But
ideally we should always place the vertical scrollbar at the end edge
of the container (whether that's the inline-end edge, when using a
horizontal writing mode, or the block-end edge, when using a vertical
writing mode).

Some functions calling the existing shouldPlaceBlockDirectionScrollbarOnLeft
instead really care about whether the vertical scrollbar is on the
left, not whether the block direction scrollbar is on the left (since
for vertical writing modes, the block direction scrollbar is the
horizontal one on the bottom). So we rename this to
shouldPlaceVerticalScrollbarOnLeft, make it return true for
writing-mode: vertical-rl, and adjust callers that really do care
only about block direction scrollbars to additionally check their
writing mode.

[macOS] Refactor some webpage translation code
​https://bugs.webkit.org/show_bug.cgi?id=224680
Work towards <rdar://75641882>

Reviewed by Tim Horton.

Source/WebCore:

In preparation for fixing ​https://webkit.org/b/224683, refactor some codepaths for handling webpage translation
via the context menu on macOS, in WebKit2.

Currently, the context menu action for ContextMenuItemTagTranslate is fully handled in the client layer in
WebKit2, using state in m_activeContextMenuContextData. However, to make this action work in WebKitLegacy as
well, we need the ability to call back into the ContextMenuController to handle the action, since context menu
actions in WebKitLegacy only target the shared WebMenuTarget instance, which only knows about the context menu
controller rather than the WebHTMLView that vended the menu item.

Instead of adding logic in WebMenuTarget to dig the WebHTMLView corresponding to the focused frame out of
the context menu controller, it makes more sense to plumb this call through the (already-established)
ContextMenuClient. While this has the disadvantage of requiring an extra IPC hop on the WebKit2 case, it also
has the advantage that we can lazily compute the selection bounds and menu location in root view coordinates
only if the user has selected this menu action, which makes context menu data (slightly) cheaper to compute.

No change in behavior.

[GPUP] WebContent process should not create AVOutputContext instances when media in GPU Process is enabled
​https://bugs.webkit.org/show_bug.cgi?id=224469

Reviewed by Eric Carlson.

Source/WebCore:

This patch modifies MediaPlaybackTargetContext to provide interfaces to serialize/deserialize
AVOutputContext and modifies MediaPlaybackTargetCocoa to use MediaPlaybackTargetContext to
manage its AVOutputContext instead of keeping a pointer to the AVOutputContext object.
With these changes, a WebContent process can forward a serialized AVOutputContext object
to other processes (e.g., the GPU process) without deserializing it. Therefore, the WebContent
process does not need access to the CoreMedia routing service. So we can remove the fix (r275669)

• UserInterface/Views/GraphicsTabContentView.js:

(WI.GraphicsTabContentView.prototype.initialLayout):
It appears that it's possible for re-entrancy issues in the WI.View system since the
_didInitialLayout flag isn't set until _after_ initialLayout returns, meaning that if
the logic inside initialLayout triggers a synchronous layout then that second layout
won't know that it's already in the middle of an initialLayout. In this case, showing the
WI.GraphicsOverviewContentView causes the navigation sidebar to be shown, which forces a
synchronous layout from handling WI.Sidebar.Event.WidthDidChange. For now, there's no
"rush" to show the WI.GraphicsOverviewContentView so we delay it by one event loop turn.

Reviewed by Daniel Bates.

By default, aliasing is applied when drawing the SVGImage to the canvas
through CanvasRenderingContext2D::drawImage() and when drawing the canvas
itself to DOM container through ImageBuffer::draw(). Because the test
includes only rectangles, we need to make sure the edges of the SVG image
and the canvas in this test get pixelated. This will match the expected
page which uses DOM objects to mimic the SVG and canvas drawing

Make sure the test is ended only after the SVG image is fully loaded.

Disable ApplicationCache with linkedOnOrAfter check
​https://bugs.webkit.org/show_bug.cgi?id=224629

Patch by Alex Christensen <​achristensen@webkit.org> on 2021-04-16
Reviewed by Brady Eidson.

Source/WebCore:

ApplicationCache has been deprecated for two years in WebKit with a message to developers since r227225.

Firefox removed support in ​https://bugzilla.mozilla.org/show_bug.cgi?id=1619673 which shipped with Firefox 84 on Dec 15, 2020.

Chrome removed support in ​https://bugs.chromium.org/p/chromium/issues/detail?id=582750 by default in Chrome 85 on August 25, 2020
but they have a reverse origin trial program running right now so that some origins have it working, but they are planning to remove
even that support October 2021.

We have kept it working for a reason related to rdar://38505756, specifically the 4th and 5th comment in that bug.
That reason is now passed.

This patch removes support for new apps but keeps it working for 3rd party apps linked with existing SDKs. Once those apps update
to a new SDK, they will be unable to use ApplicationCache. They will need to migrate to use fetch service workers instead.

Source/WebKit:

Make sure we no longer show the previous page when running a JS prompt.
If we have not yet done a layer tree commit since the last load commit, then
we are likely still showing the previous page. If we are asked to run a JS
prompt / alert / confirm at this point, it would be confusing to still show
the previous page. In order to address the issue, we now make the view blank
in such scenario (ideally, we'd have painted the new page but this is
currently not a trivial thing to do).

To make the view blank, the approach chosen is the set the opacity of our
root layer to 0 when the JS prompt is requested (before the first paint) and
set the opacity back to 1 after the first paint.

To minimize the risks of breakage, the behavior change is behind a
linked-on-after check. Also, we only trigger this behavior if the WKWebView
client actually implements the corresponding JS prompt delegate.

Reviewed by Geoffrey Garen.

Source/WebKit:

This was an IPC ordering bug. WebPageProxy::DidCommitLoadForFrame is async and WebPageProxy::CreateNewPage is
sync. As a result, it was possible for the WebPageProxy::CreateNewPage to get processed *BEFORE* the
WebPageProxy::DidCommitLoadForFrame IPC. This was causing trouble because Safari rejects the popup opening if
the main frame is doing a provisional load.

To address the issue, introduce a new IPC::SendSyncOption::MaintainOrderingWithAsyncMessages flag and
use it on WebPageProxy::CreateNewPage sync IPC so that it gets processed in order with surrounding async
messages.

Exit the GPUProcess when under memory pressure if it is not being used
​https://bugs.webkit.org/show_bug.cgi?id=224556

Reviewed by Darin Adler.

Source/WebKit:

Exit the GPUProcess when under memory pressure if it is not being used. This will
help us save memory, especially until we are able to enable "DOM Rendering in
GPUProcess".

Note that when the GPUProcess is ready to exit, it sends an IPC to the UIProcess
in order to get terminated, instead of terminating itself. The reason I do this is
so that the UIProcess can distinguish a GPUProcess crash from a normal idle exit.

A/B testing shows:

• 5-8% PLUM3 progression on iPhone
• 2.5-4% PLUM3 progression on iPad
• No PLT5 regression on either iPhone or iPad.

Early IPC messages to a WorkQueueMessageReceiver may get processed out of order
​https://bugs.webkit.org/show_bug.cgi?id=224623

Reviewed by Geoffrey Garen.

Bug 224566 exposed an issue where early IPC being sent to WorkQueueMessageReceiver might get received
out of order. The reason behind it is that the WorkQueueMessageReceiver registers itself on the main
thread while we receive the IPC on the IPC thread. When we receive the IPC on the IPC thread, we check
if there is a WorkQueueMessageReceiver for it and if there is, we dispatch the message straight to its
WorkQueue. However, if the WorkQueueMessageReceiver has not registered itself yet on the main thread,
we hop to the main thread first, before dispatching the IPC back to the receiver's WorkQueue. The
extra hop to the main thread means that 2 IPC messages to the WorkQueueMessageReceiver sent one after
the other may get dispatched on the WorkQueue in an inconsistent order, if the WorkQueueMessageReceiver
registers itself as a receiver in between the 2 IPC messages.

We actually were trying to deal with this issue in Connection::addWorkQueueMessageReceiver(). When
the WorkQueueMessageReceiver would register itself on the main thread, we would grab the incomingMessages
lock and check m_incomingMessages for messages that should be dispatched to the WorkQueue. Those are
async messages that should have been dispatched straight to the WorkQueue on the IPC thread but didn't
because the WorkQueueMessageReceiver has not registered itself yet.

However, this logic in Connection::addWorkQueueMessageReceiver() was insufficient because it only checked
m_incomingMessages. m_incomingMessages only contains async messages. Sync messages (and special async
messages with the IPC::SendOption::DispatchMessageEvenWhenWaitingForSyncReply flag) are stored in
Connection::SyncMessageState::m_messagesToDispatchWhileWaitingForSyncReply. This is what was causing
Bug 224566 since RemoteRenderingBackendProxy's CreateImageBuffer IPC was async with the
DispatchMessageEvenWhenWaitingForSyncReply flag and its GetDataURLForImageBuffer was synchronous. The
ordering of these 2 IPC messages could get reversed and it would cause correctness issues and flaky
crashes.

To address the issue, I updated Connection::addWorkQueueMessageReceiver() to ask the
Connection::SyncMessageState to enqueue its matching messages to the WorkQueue. There was one issue
though because Connection::SyncMessageState::dispatchMessagesAndResetDidScheduleDispatchMessagesForConnection()
was taking messages out of m_messagesToDispatchWhileWaitingForSyncReply and storing them in a local
container and then iterating over this container to dispatch the messages. The dispatching of one
of these messages could cause a WorkQueueMessageReceiver to register itself (call addWorkQueueMessageReceiver()).
When this would happen, addWorkQueueMessageReceiver() would try and enqueue matching messages in
m_messagesToDispatchWhileWaitingForSyncReply and would miss the messages in the local container
that dispatchMessagesAndResetDidScheduleDispatchMessagesForConnection() is currently iterating on.
To address this issue, I introduced a new m_messagesBeingDispatched data member and used that to
store the messages being dispatched instead of the local container. As a result,
addWorkQueueMessageReceiver() can now enqueue the messages in m_messagesBeingDispatched first and
then enqueue the ones in m_messagesToDispatchWhileWaitingForSyncReply.

Revert r276007 that was committed as a temporary workaround for this bug.

• Platform/IPC/Connection.cpp:

(IPC::Connection::SyncMessageState::enqueueMatchingMessages):
Add utility function to SyncMessageState to enqueue its matching messages in m_messagesBeingDispatched
and m_messagesToDispatchWhileWaitingForSyncReply to the provided MessageReceiveQueue. This is called
by Connection::addMessageReceiveQueue(). The logic is similar to the one in the
enqueueMatchingMessagesToMessageReceiveQueue() function but works on a Deque<ConnectionAndIncomingMessage>
instead of a Deque<std::unique_ptr<Decoder>>.

(IPC::Connection::SyncMessageState::dispatchMessages):
(IPC::Connection::SyncMessageState::dispatchMessagesAndResetDidScheduleDispatchMessagesForConnection):
Use m_messagesBeingDispatched instead of a local container to store the messages we are about to
dispatch. This allows enqueueMatchingMessages() to check those messages to see if they should be
dispatched to a MessageReceiveQueue. We also need to make sure we don't iterate over
m_messagesBeingDispatched to call dispatch() on the messages. This is important because any message
dispatch may cause a WorkQueueMessageReceiver to register itself, which would call
enqueueMatchingMessages() and potentially extract matching messages from m_messagesBeingDispatched.
For this reason, we take messages from m_messagesBeingDispatched one by one, until the container
becomes empty.

(IPC::Connection::addMessageReceiveQueue):
(IPC::Connection::addWorkQueueMessageReceiver):
(IPC::Connection::addThreadMessageReceiver):

• This used to only check m_incomingMessages for matching messages that should be enqueued on the MessageReceiveQueue in order to preserve IPC ordering. This was insufficient because it would fail to consider sync IPC messages (or async IPC messages with the IPC::SendOption::DispatchMessageEvenWhenWaitingForSyncReply flag). Since those are stored in separate containers in Connection::SyncMessageState, we now also call Connection::SyncMessageState::enqueueMatchingMessages() to enqueue those messages and preserve their ordering too. This fixes IPC ordering bug identified via Bug 224566.
• Avoid some code duplication by moving more logic to a shared enqueueMatchingMessagesToMessageReceiveQueue() function. The function is no longer templated because I don't think it is worth increasing binary size just to avoid the virtual enqueueMessage() function call on the MessageReceiverQueue. We do not register message receivers very often and then only have a few early messages at most to enqueue.

Refactor parameters to blending functions
​https://bugs.webkit.org/show_bug.cgi?id=224433

Reviewed by Dean Jackson.

Reduce the number of parameters passed to the blending functions such that we package
the client and progress together and track whether the animation is discrete instead
of computing it several times. This information is now passed as a BlendingContext
parameter, and a CSSPropertyBlendingContext private to CSSPropertyAnimation.

When we support composite operations, we'll just need to add a new member to that
struct instead of modifying all the method signatures.

Since we are modifying the method signatures, we also change the RenderStyle pointers
to references since we would never pass in a null value.

Source/WebCore:

We need to blend between lengths when their types are not the same. However, we would take
some shortcuts in the following cases and blend using just one value:

1. either the from or to value was a 0 value,
2. progress was 0 or 1.

Now we use the mixed types code path if the types are different or either the from or to
value is a calculated value. The single exception where we don't actually end up generating
a CalculationValue is when we know that one of the two values is 0 and not a percentage, in
which case we run a simple blend.

Due to this approach, we stopped returning the value as-is in some cases where progress was
0 or 1. To avoid regressions in this area, we made the LengthBoxPropertyWrapper clone the from
or to value in the discrete case, as some other areas of the code do not know how to deal with
calculated Length values, for instance valueForImageSliceSide(const Length&).

Reviewed by Antti Koivisto.

We construct a dedicated renderer for the first letter content and in some cases wrap it into an anonymous block.
This subtree needs to be destroyed when the associated RenderText is getting deleted. During this cleanup process
we may find the wrapper anonymous block redundant and initiate a sibling block collapsing. However this collapsing
may interfere with the initial delete (the associated RenderText) and lead to unexpected result.
Let's reserve the anonymous collapsing for the initial remove.

Reviewed by Antti Koivisto.

Source/WebCore:

This patch fixes the case when a non-overlay scrollbar can't be accomodated in the padding/content box area (e.g <div style="height: 10px; overflow: scroll">...)
In the legacy render tree the non-overlay scrollbar size is already taken into account when calling RenderBox::contentWidth/Height (paddingBoxHeight/Width), so
we just have to check how much space they actully take (currently maximum of 15px).

Avoid converting HTML chars in _W3CTestConverter
​https://bugs.webkit.org/show_bug.cgi?id=224658

Reviewed by Adrian Perez de Castro.

There has been a change in Python HTMLParser in version 3.5 that makes convert_charrefs to be True by default:
​https://docs.python.org/3/library/html.parser.html

This is causing that we're modifying the tests that have HTML characters, which is something
we shouldn't change and was not happening in previous Python 3 versions, or Python 2.

• Scripts/webkitpy/w3c/test_converter.py:

(_W3CTestConverter.init): Set convert_charrefs to False.

• Scripts/webkitpy/w3c/test_converter_unittest.py: Update test to include HTML chars and check that they're not modified.

Animated pseudo element style resolved against wrong parent style

Reviewed by Antoine Quint.
Source/WebCore:

In createAnimatedElementUpdate we get the parent and parent box styles from the parent stack.
This is wrong for pseudo elements. Their parent style should the host style which is not pushed to the stack.

This matters in style adjuster which may apply wrong adjustments as a result.
