[iOS] Coalesce adjacent selection geometries when rendering individual selection quads
​https://bugs.webkit.org/show_bug.cgi?id=225054

Reviewed by Tim Horton.

Source/WebCore:

Add a heuristic to coalesce adjacent selection geometries when SelectionRenderingBehavior::UseIndividualQuads
is active. Currently, we pass them directly through to the list of coalesced geometries inside
RenderObject::collectSelectionGeometries, but this can lead to almost perfectly adjacent selection quads
showing a narrow gap in between their selection views.

Instead, we can detect this case where neighboring quads can be united into a single quad without significantly
changing the geometry. Rather than append the new selection geometry in this case, we simply adjust the last
selection geometry's quad so that it encompasses the new selection geometry as well, by extending the top right
and bottom right extent points of the last selection quad to the new selection quad's extent points.

See below for more details.

Test: fast/images/image-extraction/ios/coalesce-selection-rects-in-image-overlay.html

• html/HTMLElement.h: WEBCORE_EXPORT a couple of helper methods.
• rendering/RenderObject.cpp:

(WebCore::RenderObject::collectSelectionGeometriesInternal):

Avoid sorting selection geometries by bounding rect logicalLeft in the case where we're not coalescing
bounding rects (and also update the preceding comment accordingly).

(WebCore::coalesceSelectionGeometryWithAdjacentQuadsIfPossible):

Add a new helper to unite neighboring quads if: (1) the top right and bottom right of the current quad are very
close to the top left and bottom left of the next quad (respectively), and (2) the angle of rotation of the
bounding rect of the current quad is very close to that of the next quad.

(WebCore::RenderObject::collectSelectionGeometries):

Use the above helper method to either coalesce or append selection geometries to the final vector of coalesced
geometries.

Source/WebKit:

Make some further minor adjustments to selection behavior in image overlays on iOS. In particular, when using
selection handles to modify the selected range, shift the start and end of the selected range so that they're at
the beginning and end of text runs, respectively.

• dom/Position.h:

(WebCore::Position::isInTreeScope const): Deleted.

Source/WebKit:

The fix for this crash that I landed in r276688 was based on a misunderstanding that accessing treeScope()
would trigger a null pointer deref if isInTreeScope() is false. This is not the case, since the treeScope
of a Node is a separate notion from whether that Node is connected to said tree scope.

Since this crash is really due to dereferencing a null container node in the case where selectionStart or
selectionEnd are null, a better fix is to just check the nullity of the container node.

Make sure we invalidate the iterator in StorageMap::clear()
​https://bugs.webkit.org/show_bug.cgi?id=225164

Reviewed by Alex Christensen.

I recently introduced StorageMap::clear() but failed to call invalidateIterator()
like we do in other StorageMap functions that modify the internal HashMap. Since
we cleared the HashMap, we don't want to be keeping a HashMap iterator around.
Looking at the code, I do not think this can cause crashes because the
index >= length() check would fail in StorageMap::key(unsigned). That said, it
is best not to keep a bad iterator around.

[iOS] [GPU] The UI process should issue mach sandbox extensions to 'iconservices'
​https://bugs.webkit.org/show_bug.cgi?id=225111
<rdar://problem/68366888>

Reviewed by Per Arne Vollan.

In Bug 205443 we did work to extend access to non-web-browsing services to the WebContent process only when
needed. This was lost in the transition to the GPU Process, and should be added back.

This change does the following:

1. Adds sandbox extension handles for the iconservices (and related) services to the GPU process creation parameters.
2. Updates the GPUProcessProxy to extend iconservices when waranted, and add them to the creation parameter structure.
3. Updates the GPUProcess to consume the extensions (when granted).
4. Makes a GPU process-specific version of the 'nonBrowserServices' static function for use by GPUProcessProxy. This is needed because fewer services are needed in the GPU process than in the WebContent process.
5. Removes unused telemetry from the WebContent process sandbox.
6. Switches the GPU process sandbox to deny iconservices (and related) by default, and to consume the extensions instead.

Tested by exisiting TestWebKitAPI tests.

Reviewed by Geoffrey Garen.

Source/WebKitLegacy/mac:

In r275912 I turned off all plugin support in WebView after looking into use of NP_Initialize, the entry point for NPAPI plugins.
That was too aggressive, as we found some use of the older WebKit plugin entry point, plugInViewWithArguments, and reverted in r276652.

Fix exception assertions in light of the TerminationException.
​https://bugs.webkit.org/show_bug.cgi?id=225128
rdar://76694909

Reviewed by Robin Morisset.

JSTests:

• stress/suppress-TerminationException-in-JSFunction-prototypeForConstruction.js: Added.

Source/JavaScriptCore:

Some pre-existing functions assertNoException() or releaseAssertNoException().
These assertion may not be valid anymore in light of the TerminationException, and
require some fix up:

1. If it makes sense to convert the assertion into an exception check, then do so.

For example, see objectPrototypeToString(), slow_path_create_this().

2. If the assertion is at the end of a function just before it returns, or if the remaining code in the function will not be affected by the pending exception, then we can replace the assertion as follows:

assertNoException() => assertNoExceptionExceptTermination()
releaseAssertNoException() => releaseAssertNoExceptionExceptTermination()

For example, see objectPrototypeHasOwnProperty(), JSObject::getOwnNonIndexPropertyNames().

3. If the assertion is in a function where perf is not absolutely critical, and the function isn't calling any other functions that will re-enter the VM or potentially get stuck in an infinite loop, then we can use a DeferTermination scope to defer termination.

For example, see Debugger::pauseIfNeeded(), SamplingProfiler::StackFrame::nameFromCallee().

4. If the assertion is in an initializer function is only run once and adding exception checks would complicate the code more than it's worth (an engineering judgement), then use a DeferTermination scope.

For example, see ProgramExecutable::initializeGlobalProperties(), setupAdaptiveWatchpoint().

Some leaf (or near-leaf) functions that currently DECLARE_CATCH_SCOPE() may also
fall under this category.

For example, see JSFunction::prototypeForConstruction().

GStreamer ports aim to reduce usage of the GStreamer library in the UIProcess and thus
should not relay capture devicechange monitoring to the UIProcess. For the long term we plan
to migrate media processing to the GPUProcess but for now we have to maintain the media
pipelines in the WebProcess. Initializing GStreamer in multiple processes (including the
UIProcess) has a significant performance impact on embedded platforms, that's why we try to
avoid it as much as possible.

The device monitoring code from the UserMediaProcessManager was partly moved to the
RealtimeMediaSourceCenter so that it can be easily reused by GStreamer ports from the
UserMediaPermissionRequestManager.

Reviewed by Darin Adler.

The crash would happen when replyToPendingMessages() get called in the AuxiliaryProcessProxy
destructor and there would be a pending getGPUProcessConnection() IPC. The lambda in
WebProcessPool::getGPUProcessConnection() would check if a WeakPtr to the WebProcessPool is
valid before calling ensureGPUProcess().getGPUProcessConnection(). However, at this point,
the WebProcessPool destructor is still running so the WeakPtr is still valid but
ensureGPUProcess().getGPUProcessConnection() will crash because the GPUProcessProxy
destructor has already run.

• UIProcess/WebProcessPool.cpp:

(WebKit::WebProcessPool::~WebProcessPool):
Drop code that was causing the GPUProcessProxy to reply to all its pending IPC messages whenenever
a WebProcessPool gets destroyed. This is incorrect since a GPUProcessProxy may be shared by several
WebProcessPool objects. Note that the AuxiliaryProcessProxy destructor already takes care of
calling replyToPendingMessages().

Protect the WebProcessPool is the lambda to prevent the case where this lambda gets called and the

Merge r275596 - [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.

Merge r275599 - [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()

Merge r275528 - [GStreamer] At EOS, change position to match duration, not the other way around.
​https://bugs.webkit.org/show_bug.cgi?id=224237

Reviewed by Philippe Normand.

The criteria used to check if playback has finished is currentTime >=
duration. Currently MediaPlayerPrivateGStreamer::didEnd() ensures this
in an awkward way: by changing the duration so that it matches
currentTime, rather than the other way around.

This meant a duration change at the end of playback most of the time,
with a slightly different duration each time, since currentTime is
cached periodically.

This patch reworks that function to work more naturally and less racy:

First, only if the stream doesn't have a set duration (e.g. live
stream), we set a duration to currentTime, as defined in the spec.

Second, at EOS we update currentTime to match duration, rather than
the other way around.

This patch doesn't introduce changes in test results.

In a shining example of "disappointing library practices", ICU 69 deprecates ubrk_safeClone in favor of

This patch introduces a function cloneUBreakIterator to abstract over this change; however, since we need to:

1. confine the effects of disabling U_HIDE_DRAFT_API to a non-unified implementation file
2. still be able to include ubrk.h from IntlSegmenter.h to instantiate ICUDeleter<ubrk_close> (*not* clone!)

[WPE][GTK] More correct fixes for stack size issues on musl libc

Patch by Daniel Kolesa <Daniel Kolesa> on 2021-04-28
Reviewed by Adrian Perez de Castro.

Partial revert ​https://bugs.webkit.org/show_bug.cgi?id=210068

Source/JavaScriptCore:

After fixing the thread stack issues in WTF properly, we can revert
the JSC options changes, which are actually harmful since they result
in JSC being unstable. Previously, softReservedZoneSize was causing a
crash when set to 128K because of the main thread stack bounds, and
this is now fixed. We can keep the maxPerThreadStackUsage at 5M as
well; there is no fundamental difference from how things are done on
glibc anymore.

• runtime/OptionsList.h:

Source/WTF:

While the changes in r236306 stopped JSC from crashing outright,
they are not correct, since they also make it rather unstable.

To counter this, increase stack size for threads on Linux with
non-glibc/bionic libcs to 1 megabyte, which is a robust enough
value that should always be sufficient.

While at it, the previous approach to musl thread stack size was
breaking use of DEFAULT_THREAD_STACK_SIZE_IN_KB (if defined) as
well as not properly taking care of the unused parameter. Move
the code to a more appropriate place, which solves these problems.

All this is however not enough, since there is still the main thread;
using pthread_attr_getstack on a main thread is not reliable since main
thread stacks are allowed to grow, and we expect the bounds to always
be constant. On glibc, this already behaved right, but e.g. on musl
(and possibly other C libraries) this is not necessarily the case - at
the point of the check, it was returning 128k (since that's the initial
size reserved by the kernel). Therefore, do the same thing as on Darwin
and use process resource limits to get the boundary on Linux as well.

This results in JavaScriptCore behaving correctly on musl libc and
allows us to drop the options special-casing that was in place.

Memory pressure events should be logged to com.apple.WebKit subsystem
​https://bugs.webkit.org/show_bug.cgi?id=225112

Reviewed by Chris Dumez.

Currently memory pressure events are logged to the default os_log subsystem instead of the
com.apple.WebKit subsystem. This makes it hard to capture such events using common logging
prefs (e.g. a pref that persists all logs from the WebKit subsystem).

To fix this, call WTFInitializeLogChannelStatesFromString at init time. This associates the
WTFLogChannel with an os_log object that sends the messages to the WebKit subsystem.

Web Inspector: Default Audits script are minified in release builds
​https://bugs.webkit.org/show_bug.cgi?id=225009

Reviewed by BJ Burg.

Source/WebInspectorUI:

Covered by new test:

• inspector/audit/non-minified-default-audits.html

The default audits have been moved out of AuditManager.js and into a special DefaultAudits.js in the new
NonMinified directory, which contains JavaScript sources that should be included in Main.js and
TestCombined.js, but should not have whitespace stripped from their contents because the whitespace is
important to the script. For example, the source for the default audits are visible to the user, and therefore
we want to present well-formatted source in those contexts.

• Scripts/combine-resources.pl:
• Added NonMinified directory to list of default inputDirectoryPattern exceptions for combining resources.
• Added --skip-concatenate-tag so that we don't add tags for script we will eventually append to another script.
• Scripts/copy-user-interface-resources.pl:
• Handle NonMinified directory for sources that will be appended to Main.js, but should not be minified.
• Handle NonMinified directory for sources that will be appended to TestCombined.js.

Make TestInput immutable
​https://bugs.webkit.org/show_bug.cgi?id=224989

Reviewed by Jonathan Bedard.

The main point here is moving computing reference_files and
should_run_pixel_test to when we initially construct TestInput, as at
this point this happens in the some process and thread (since bug
221577), hence there's no real reason for it to happen later.

In doing this, I've eliminated Port.should_run_as_pixel_test on the
basis that no port actually overrode this to apply any different logic,
especially given it seems unlikely that any port would want to use
different logic here. (Note that ports still have some control through
Port.default_pixel_tests.)

With this done, it should then be possible to make TestInput immutable,
which should help make things easier to understand.

Expect, as it happens, there was a reason for it to happen later: we
previously generated all the TestInputs twice, once to find out how
many workers we need and then another time to actually run them (plus
potentially a third time for retries!). There's no actual reason to do
this, so move the creation to Manager.run and pass that list around
instead of the Tests.

numCalleeLocals, numParameters, and numVars should be unsigned
​https://bugs.webkit.org/show_bug.cgi?id=224995

Reviewed by Mark Lam.

All of the various CodeBlock classes currently have the
numCalleeLocals and numVars marked as ints. I believe this is just
a historical artifact or because VirtualRegister's offset is an
int to make handling constants easier. Regardless, it's a bit
strange to not handle the sign conversion at the point of
comparison between a VirtualRegister offset and the local/var
count. This doesn't completely fix every place we use ints for
these values but starts on the right track. Lastly, I also added
some Check<unsigned>s to the wasm parser for sanity checking.

Remove redundant frameDetached() from the SVGImage destructor
​https://bugs.webkit.org/show_bug.cgi?id=221616
<rdar://problem/74149106>

Reviewed by Chris Dumez.

SVGImage was originally written such that it has two separate objects:
a page and a frame; see ​https://trac.webkit.org/r18470. So it made sense
at that time to clean up the page and the frame separately. The Frame
was cleaned up by telling the frame's loader that the frameDetached().

This code is not necessary right now since the page owns the main frame.
And its destructor recursively detaches itself from all the frames.

[JSC] Remove defaultValue() from the method table
​https://bugs.webkit.org/show_bug.cgi?id=225032

Reviewed by Darin Adler.

Source/JavaScriptCore:

This patch not only removes the unnecessary method table entry, but also makes
the presence of custom ToPrimitive behavior observable to userland code.

To maintain object identity and (possibly) enable caching, Symbol.toPrimitive
method is stored on a structure. To avoid any potential breakage, it's made
replaceable and configurable, covering the case when its holder is a ProxyTarget.

For JSCallbackObject, Symbol.toPrimitive method is created only if ConvertToType
callback is present, before initialization is performed.

Also, this change adds additional ordinaryToPrimitive() cast to fix the invariant
that toPrimitive() returns a primitive value, which was broken if ConvertToType
callback returned an object. The invariant is enforced by the spec [1][2] and is
validated via assertion in JSValue::toStringSlowCase().

Copy-on-write semantics should be an internal implementation detail of StorageMap
​https://bugs.webkit.org/show_bug.cgi?id=225108

Reviewed by Alex Christensen.

Source/WebCore:

Instead of making the StorageMap RefCounted and requiring the client to potentially
replace its StorageMap whenever it calls functions that modify the StorageMap, the
copy-on-write semantics in now an internal implementation detail of StorageMap.

To achieve this, the following changes were made:

• StorageMap is no longer RefCounted. Instead, it has an internal Impl data member that is RefCounted.
• The internal Impl data member is the one that gets copied on write.
• Functions that modify the StorageMap no longer need to return a StorageMap.
• Add a clear() function for convenience.

[iOS][FCR] Add borders for better control visibility
​https://bugs.webkit.org/show_bug.cgi?id=225058
<rdar://problem/77161616>

Reviewed by Sam Weinig.

Source/WebCore:

The solid gray backgrounds of new form controls have poor visibility on
site's that have gray-ish backgrounds or draw the controls on top of
a gray area. To fix this, borders are added to all controls to ensure
visibility no matter the background.

The border color is the system background color. This means the border
is invisible on white backgrounds in light mode, and dark backgrounds
in dark mode, ensuring the controls match UIKit styles on backgrounds
where they are guaranteed to be visible. However, these borders are
visible when the page/area background has a similar color to the control
background, improving control visibility.

To paint the borders, a mix of UA stylesheet changes and custom painting
changes are used. This approach is taken to maintain our existing level
of stylability. UA stylesheet changes were applied to controls that
specified a "1px solid black" border in the old design. The border is
now brought back, but with a different color. For controls that have
always had completely custom painting (independent of styles), the
border is painted by the theme.

• css/html.css:

Specify a "1px solid -webkit-control-background" border on controls
that previously (pre-redesign) specified a border in the UA stylesheet.

• css/legacyFormControlsIOS.css:

(select:focus):

Move the <select> focus style into the legacy stylesheet, since it
should not apply to the new design.

• rendering/RenderThemeIOS.mm:

(WebCore::RenderThemeIOS::paintCheckbox):

Paint the checkbox border inside the painting rect, and inset the
actual checkbox by the border. This is necessary, checkboxes use
"box-sizing: border-box", and we do not want to increase the overall
size of checkboxes for compatibility reasons.

(WebCore::RenderThemeIOS::paintRadio):

Painted in a similar manner as checkboxes.

(WebCore::RenderThemeIOS::paintProgressBarWithFormControlRefresh):
(WebCore::RenderThemeIOS::paintMeter):
(WebCore::RenderThemeIOS::paintSliderTrackWithFormControlRefresh):

Slider tracks are already inset by the border size, so we can just
draw a border in the available area.

Source/WebCore:

Although window.CSS is the only namespace object currently handled by code generator,
it's being extended by multiple Houdini specs [1], so keeping it generated is important.

This patch brings spec compliance [2] and web interop while striking a balance between
reducing generated code, avoiding indirection in the generator, and a small code diff.

Feature-wise, a namespace object is a subset of an interface; so instead of creating a
separate harness for it, like for callback interfaces, namespace objects are converted
to interfaces before being handed over to code generator, with a flag on.

While we can reduce the generated code even further, namely around subspaceForImpl(),
this change rather aligns namespace objects with [JSBuiltin] interfaces to avoid making
generator more complicated and introducing an interface with distinct set of methods.

Web-facing changes for window.CSS are:

1. Removed Call and Construct methods, making typeof CSS return "object", which is used for feature detection (thus important for web interop).
2. Removed "length" / "name" / "prototype" properties.
3. Changed Prototype value to %Object.prototype%.
4. Added Symbol.toStringTag property with correct descriptor.

All of the above were proven web-compatible by Blink and Gecko.

Also, this patch limits the usage of NeedsConstructorProperty only to
%Interface%.prototype.constructor, as its name suggests.

Don't keep local storage data in memory in the NetworkProcess

Add a clear() function to StorageMap so that StorageArea doesn't reconstruct a
new StorageMap object unnecessarily when:

• The StorageMap is not shared
• The StorageMap is empty (and clear() is a no-op)

Source/WebKit:

When a WebPage would start to use the local storage API, the WebProcess
would send a sync IPC to the NetworkProcess to retrieve all the local
storage entries for the origin. The NetworkProcess would read those
entries from a SQLite database and send them back to the WebProcess.
Both the NetworkProcess would keep the entries in memory, in a
StorageMap object (which is basically a HashMap). On some sites, the
strings in the local storage may be very large. It is useful for the
WebProcess to keep them in memory for performance reasons, especially
considering that the Web API is synchronous. However, there is no real
need to keep them in memory in the Network Process side, especially
given that the WebProcess already has its own copy. On the network
process side, we can get rid of the StorageMap entirely in the local
storage case and 100% rely on the SQLite database. This is what this
patch implements.

A/B testing shows this is a 2-3% progression on Membuster. There does
not appear to be a meaningful progression on PLUM sadly. This is also
neutral on PLT.

For some reason, when running this layout test in a newly created simulator, the drag cancel preview animation
will finish animating *just* before the "dragend" event is dispatched, which causes the test to fail with a text
diff due to the missing PASS Ended drag output.

Address this by making the test robust in both cases (where the animation ends before the page receives
"dragend" and vice versa) by only finishing the test when we've met both conditions.

[MathML] Assertion failure in RenderTreeNeedsLayoutChecker
​https://bugs.webkit.org/show_bug.cgi?id=224903

Patch by Frédéric Wang <​fwang@igalia.com> on 2021-04-27
Reviewed by Alan Bujtas.

Source/WebCore:

After r226180, RenderMathMLRow no longer performs layout of its "embellished operator"
children only its core <mo> descendant, which is causing dirty layout.

Test: mathml/vertical-embellished-op-dirty-layout.html

• rendering/mathml/RenderMathMLRow.cpp:

(WebCore::RenderMathMLRow::stretchVerticalOperatorsAndLayoutChildren): always layout the
"embellished operator" child, after its core <mo>.

LayoutTests:

Add regression test with all vertical embellished operators (other than <mo>) supported
by WebKit.
