[LFC][RenderTreeDump] Expand RenderInline 0 height quirk logic to previous/next siblings
​https://bugs.webkit.org/show_bug.cgi?id=220884

Reviewed by Simon Fraser.

Check the previous/next siblings to see whether we should apply the zero-height quirk on the current RenderInline.
Note that this does not change the RenderInlines' reported height values on trunk.
However it greatly helps to reduce the required rebaseline when LFC's inline box support is enabled (see webkit.org/b/220148).

• GPUProcess/graphics/RemoteRenderingBackend.cpp:

Add macro definitions for MESSAGE_CHECK and MESSAGE_CHECK_WITH_RETURN_VALUE. Since the methods on
RemoteRenderingBackend that trigger message checks all run on a background queue, the normal (main-thread) way
of defining these macros (MESSAGE_CHECK_WITH_RETURN_VALUE_BASE and MESSAGE_CHECK_BASE) don't work. We
instead call into the GPU to web process connection object directly to send a TerminateWebProcess message to
the parent (UI) process, and additionally log a given failure message.

(WebKit::RemoteRenderingBackend::nextDestinationImageBufferAfterApplyingDisplayLists):

Replace a number FIXMEs throughout these IPC message handlers with MESSAGE_CHECKs. Additionally, add a new
MESSAGE_CHECK for the case where we stopped replay early due to a corrupted or invalid display list item.

(WebKit::RemoteRenderingBackend::wakeUpAndApplyDisplayList):
(WebKit::RemoteRenderingBackend::setNextItemBufferToRead):

Simply remove the FIXME and early return here; this can only happen in the case where a compromised web content
process attempts to append redundant item buffer change items. However, doing so will either be (1) harmless,
since the pending item buffer information will just be overwritten, or (2) result in hitting a MESSAGE_CHECK
when decoding items if we try to execute the contents of another item buffer that has not been written to.

[iOS WK2] Make the "in stable state" bit in visible content rect updates more fine-grained
​https://bugs.webkit.org/show_bug.cgi?id=220875

Reviewed by Tim Horton.

VisibleContentRectUpdateInfo contains a single "in stable state" bit, but in a future
patch the web process will need to know if the UI process is rubberbanding. In addition,
we can fold "isChangingObscuredInsetsInteractively" into the same state bits.

So give VisibleContentRectUpdateInfo a OptionSet<ViewStabilityFlag>.

To give the correct state for non-main UIScrollViews, have _scrollViewIsRubberBanding
take the UIScrollView in question, and only include isChangingObscuredInsetsInteractively
if the question is being asked of the main UIScrollView.

REGRESSION(r266148) Cancelling a navigation in decidePolicyForNavigationAction should not suspend the previous document's font loading timer
​https://bugs.webkit.org/show_bug.cgi?id=220882
<rdar://problem/71634501>

Patch by Alex Christensen <​achristensen@webkit.org> on 2021-01-22
Reviewed by Brady Eidson.

Source/WebCore:

Things like the load event and didFinishNavigation wait until loading of things like fonts and iframes has completed.

If we navigate to a document that immediately tries to navigate to a different document after starting the loads of fonts,
then we momentarily have two DocumentLoaders with m_frame pointing to the same main frame.

If we cancel that second navigation using WKNavigationActionPolicyCancel, then it calls DocumentLoader::stopLoading on the second DocumentLoader.
This is fine. This is the way things have worked for a very long time.

r266148 introduced a call to the document's font loader's suspendFontLoadingTimer inside of DocumentLoader::stopLoading which is also fine.
What is not fine is the way we get that document. Using m_frame->document() in this case gets us the first document, which may still be loading fonts that we do still want.
Using this->document() only returns non-null if this DocumentLoader is the DocumentLoader that was used to load the Frame's Document,
and in this case the DocumentLoader should only stop the font loading timer if that is true.

I added an API test that reproduces the issue before but not after this fix.
For further verification, you can replace server.request() in my API test with a request to the URL in the radar ending in "Authentication.htm"
and verify it times out before the fix but not after.

This is close to the largest amount of time spent per character changed I've ever written to change "m_frame" to "this".

[webkitpy][GTK] Xvfb driver fails to start with python3
​https://bugs.webkit.org/show_bug.cgi?id=220870

Reviewed by Jonathan Bedard.

Python2 and Python3 differ in how they handle file descriptor inheritance
and Popen's close_fds default value.

In Python2, os.pipe creates the fds with the inheritable flag set, and
Popen's close_fds defaults to True.

In Python3, os.pipe creates the fds non-inheritable, requiring a call
to os.set_inheritable to enable it. Also, Popen's close_fds defaults
to False, closing all file descriptors except stdin, stdout and stderr.

With this commit, Python3 is able to launch the Xvfb driver for
run-webdriver-tests, but is still failing later with some pytest issue
to be tracked in another bug.

[WPT] [Payment Request] slight adjustment to payment-request/payment-request-constructor-thcrash.https.html
​https://bugs.webkit.org/show_bug.cgi?id=220872

Reviewed by Andy Estes.

The first test in payment-request/payment-request-constructor-thcrash.https.html is
incorrect because duplicate items in methodData provided to PaymentRequest should throw
a RangeError according to step 4.3.3 of <​https://www.w3.org/TR/payment-request/#constructor>.

The spec does mention in <​https://www.w3.org/TR/payment-request/#conformance>

User agents _MAY_ impose implementation-specific limits on otherwise unconstrained inputs,
e.g., to prevent denial of service attacks, to guard against running out of memory, or to
work around platform-specific limitations. When an input exceeds implementation-specific
limit, the user agent _MUST_ throw, or, in the context of a promise, reject with, a
TypeError optionally informing the developer of how a particular input exceeded an
implementation-specific limit.

but does not specify whether this should happen before or after the above.

In WebKit's case, there is no "implementation-specific limit", so a TypeError should not
be thrown in either case.

DisplayList::Replayer should stop replay and inform clients after encountering an invalid item
​https://bugs.webkit.org/show_bug.cgi?id=220867

Reviewed by Chris Dumez.

Source/WebCore:

Make the DisplayList item iterator emit Optional<ItemHandle> instead of just ItemHandle; in the case of
client decoding or item validation failures (see #220710), this item handle will be WTF::nullopt. The display
list replayer will then handle this by halting replay with StopReplayReason::InvalidItem.

This refactoring will eventually enable RemoteRenderingBackend (in the GPU process) to terminate the web
content process when we fail to decode a display list item during playback (or encounter an invalid inline
item).

Patch by Ziran Sun <Ziran Sun> on 2021-01-22
Reviewed by Manuel Rego Casasnovas.

When setting an override logical-height the definiteness can change causing %-height
children to resolve differently. This change adds this check to determine if a grid-item
needs relayout. It is an import of Chromium changes at
​https://chromium-review.googlesource.com/c/chromium/src/+/2474917
Instead of adding maybeHasPercentHeightDescendant() in WebKit, this change calls
hasPercentHeightDescendants(). In Chromium it wasn't possible to use
hasPercentHeightDescendants() because of this quirk:
​https://quirks.spec.whatwg.org/#the-percentage-height-calculation-quirk
WebKit doesn't seem to use the quirk for grid according to the image in

Add a new PaymentRequest value to the ChannelSource enum.

Source/WebCore:

The Payment Request API defines a selected property of PaymentShippingOption that is
used to control the initially selected shipping option when showing/updating a payment
request. Currently, PKShippingMethod does not have an equivalent concept and instead just
uses the first item in the -[PKPaymentRequest setShippingMethods:] such that there is
always a selected PKShippingMethod. This patch adjusts WebKit to follow those same
conventions, in that the first item in paymentDetailsBase.shippingOptions is used as the
selectedShippingOption so as to avoid situations where PassKit displays the first shipping
option while PaymentRequest.prototype.get shippingOption has a different value, which
could result in the user authorizing a payment with different shipping details than what
they were shown. Ideally in the future PassKit will add API/SPI to allow us to undo this.

Source/WebCore:

Scroll latching for momentum scrolls was too sticky; it would keep latching to the same
scroller within a 100ms of the last event that was handled, which was exacerbated by the
fact that ScrollController can go into "ignoreMomentumScrolls" mode which results in
no visible scrolling but continued consumption of momentum wheel events.

Fix by releasing the latch as soon as we see the end of a momentum scroll,
so that we always re-evaluate latching at the start of the next gesture.

To avoid clamping device independent colors to sRGB we convert colors without a direct

While CoreGraphics does support the Lab colorspace on some systems (Big Sur and later),

most coverage.

This happens because the development XPC service does not have the required private entitlement to enable message filtering in the sandbox,
and therefore fails to apply the sandbox. The existing runtime switching to enable message filtering based on the presence of the entitlement
is not working correctly. The 'if' clause checking the sandbox parameter in the sandbox cannot be nested inside an 'allow' clause, it appears.

Source/WebCore:

The Payment Request API spec indicates that when updating a PaymentRequest's details [1]
we should be checking for the existence of displayItems, shippingOptions (but only if
requestShipping was specified), and modifiers before overriding any corresponding data
on the PaymentRequest itself. This means that calls to updateWith only need to provide
the data that needs to be changed (e.g. the total) rather than data for the whole payment.

REGRESSION (Async overflow): Scroll stutters/blocked with nested scrolling
​https://bugs.webkit.org/show_bug.cgi?id=219923
<rdar://72390196>

Reviewed by Sam Weinig.

When handling wheel events in overflow:scroll areas which are only scrollable on
one axis, particularly when nested, we need to account for the different
scrollability on each axis in a couple of places.

First, address the FIXME in ScrollingTreeScrollingNodeDelegateMac::shouldRubberBandInDirection()
by consulting node scrollability; this prevents attempts to rubberband on a non-scrollable
axis.

Second, ScrollController should only allow stretching on a scrollable axis.

The effects of these changes are that we no longer keep sending events to a node which
ends up not handling them; this resulted in latching "timing out", re-hit-testing
in the middle of a gesture and causing stuttery position changes on a different
scroller.

Rework color clamping logic to be consistent and clear
​https://bugs.webkit.org/show_bug.cgi?id=220716

Reviewed by Simon Fraser.

In preparation of adding support for Extended-sRGB to color types,
this adds constexpr metadata and helper functions to create color
types with the correct clamped (or unclamped) values and adopts them
throughout the code base.

• Removes "component bytes" and "component floats" concepts replacing with functions that take color types as template parameters:

convertToComponentBytes/convertToComponentFloats -> convertTo<ColorType<T>>
clampToComponentBytes/clampToComponentFloats -> makeFromComponentsClamping<ColorType<T>>

• Adds Model type aliases to each color type which can specify traits for that type of color. These traits currently only include the valid component ranges and whether the color can be inverted. More will be added (like white point and base color space) to help simplify utility and conversion code.

• Adds assertions to each color type constructor that the values passed are within the valid ranges (as specified by the Model).

• Removed asFoo(const ColorComponents<T>&) functions, which were a little to similarly named to the toFoo() functions. Instead, the generic makeFromComponents<ColorType<T>> (or it's clamping variants) can be used to convert from ColorComponents to color types.

• Adds AlphaTraits to model alpha values as these are consistent between color types and only change based on component type.

[macOS] Titlebar separator doesn't show when WKWebView is scrolled
​https://bugs.webkit.org/show_bug.cgi?id=220633
<rdar://problem/71094055>

Reviewed by Tim Horton.

Source/WebKit:

Starting in Big Sur, NSWindows with a titlebar display a separator if
there is a scrolled NSScrollView adjacent to the titlebar. Since
WKWebViews are scrollable views, but not backed by NSScrollView, we
need to adopt SPI to support this functionality.

This patch updates WKWebView to conform to the NSScrollViewSeparatorTrackingAdapter
protocol, ensuring the titlebar separator is displayed when
necessary. Note that since WKWebViews are not actually NSScrollView's we
don't already have the scroll position of the view in the UIProcess. To
determine whether or not the view is scrolled, this patch adds plumbing
so that the WebProcess can tell the UIProcess the new scroll position
when a page is scrolled.

[macOS] Include an origin identifier when writing promised image data to the drag pasteboard
​https://bugs.webkit.org/show_bug.cgi?id=220782

Reviewed by Megan Gardner.

Source/WebKit:

Add plumbing in WebKit to serialize and write the pasteboard origin identifier via custom data when dragging an
image with promised data on macOS. In the case where we're dragging an image into a contenteditable area in a
document with the *same* pasteboard origin, this allows us to avoid sanitizing the web archive data upon
handling the drop.

Accelerate HTMLInputElement creation
​https://bugs.webkit.org/show_bug.cgi?id=220758

Reviewed by Simon Fraser.

HTMLInputElement creation is too slow.

1. InputType is excessively using virtual dispatching, which is too slow for hot path.
2. HTMLInputElement creates internal elements as a shadow DOM and its creation is too generic.
3. We are setting inner text element's editability in a very generic way. This allocates ElementData for each elements while attributes are almost the same.

In this patch,

1. We add m_type field in InputType, and for the hot path, we attempt to devirtualize things due to performance problem.
2. We pass "parsing phase" information to shadow DOM creation to make them fast.
3. We initialize editibility when creating TextControlInnerTextElement. And we use parserSetAttributes to set shared ElementData. This is faster and less memory.
4. We also shrink sizeof(Style::Scope) to reduce size of allocation when using shadow DOM.

This change offers 1% progression in Speedometer2/jQuery.

[iOS] "touchend" events should be dispatched and handled asynchronously
​https://bugs.webkit.org/show_bug.cgi?id=220256
<rdar://problem/64912551>

Reviewed by Tim Horton.

Source/WebKit:

Allow active "touchend" event listeners to send asynchronous (non-blocking) IPC messages to the web process by
augmenting the content view's deferring gesture recognizers. See below for more details.

Test: fast/events/touch/ios/click-event-after-touchend.html

• UIProcess/PageClient.h:
• UIProcess/WebPageProxy.cpp:

(WebKit::WebPageProxy::handlePreventableTouchEvent):

Send both "touchstart" and "touchend" events asynchronously.

• UIProcess/WebPageProxy.h:

(WebKit::WebPageProxy::isHandlingPreventableTouchEnd const):

In a similar way to how we defer "touchstart", add a counter to keep track of when we're handling an active
(preventable) touchend, such that we can defer all native gestures that can be prevented by touchend until after
the page is done handling the event.

(WebKit::PageClientImpl::doneDeferringTouchEnd):

• UIProcess/ios/WKContentViewInteraction.h:
• UIProcess/ios/WKContentViewInteraction.mm:

(-[WKContentView setUpInteraction]):

Add a new set of deferring gesture recognizers that can be used to defer all tap gestures on the content view,
due to active "touchend" event listeners. This works because currently, the only default gestures in WebKit
that can be prevented by calling preventDefault() on "touchend" events are tap gestures.

(-[WKContentView _doneDeferringTouchEnd:]):

Add a hook to "lift" the gesture gate upon touchend, which allows all deferred tap gestures to either fail (in
the case where the page prevented default), or recognize (in the case where the page did not prevent default).

(-[WKContentView gestureRecognizer:shouldRecognizeSimultaneouslyWithGestureRecognizer:]):

Replace _touchStartDeferringGestures with _deferringGestures in several call sites that need to iterate over
all deferring gestures on the content view.

(-[WKContentView _singleTapDidReset:]):

When resetting the single tap gesture, ensure that the tap highlight view is removed by calling
-_finishInteraction; this is because an active touchend event handler may now defer -_singleTapRecognized:
until after the ending the touch, which causes -_showTapHighlight to be called without a matching call to
remove the highlight. Since we know that the synthetic tap gesture must eventually be reset after recognition,
this is a more suitable catch-all for removing the tap highlight.

(-[WKContentView deferringGestureRecognizer:shouldDeferOtherGestureRecognizer:]):

For the "touchend" deferring gesture recognizers, partition all tap gestures on the content view into three
subgraphs that mirror the extant gesture subgraphs currently used for the "touchstart" deferring gestures. This
ensures that synthetic clicks always remain fast when the blocking double tap gesture is disabled, and that
other tap gestures (such as the text interaction multi-tap gesture) are still immediately reset.

LayoutTests:

Add a layout test to verify that calling preventDefault() in an active touchend event listener prevents a
click event from being dispatched, and that a click event is dispatched when there is an active touchend event
listener which does not prevent default.

[Mac] Netflix controls do not fade out after entering fullscreen
​https://bugs.webkit.org/show_bug.cgi?id=220472
<rdar://70602577>

Reviewed by Eric Carlson.

Test: TestWebKitAPI/Tests/mac/FullscreenPointerLeave.mm

Netflix uses a "pointerleave" event over their playback controls to trigger setting their "fade out controls"
timer, but a "pointerleave" event isn't fired when the element moves out from under the pointer (either due to
style changes, or the window screen location moving due to entering fullscreen).

Work around this behavior by sending a synthetic mouse event after entering fullscreen, which causes the
"pointerleave" event to be fired if, indeed, the pointer is no longer over the element in question.

REGRESSION (Big Sur): position:absolute elements inside nested overflow:scroll don't track scrolling
​https://bugs.webkit.org/show_bug.cgi?id=220761
<rdar://problem/69075263>

Reviewed by Antti Koivisto.
Source/WebCore:

When a position:absolute element is inside nested overflow scroll, and its containing block is the outer
scroller, then we failed to make a positioning scrolling tree node for it, so it would fail
to track during async scrolling.

The bug was that RenderLayerCompositor::layerScrollBehahaviorRelativeToCompositedAncestor() failed
to deal with nested scrollers. The correct question to ask when determining if we need a "Moves" node
is "is there an overflow scroll layer between this layer and its composited ancestor". Previously,
we would just find the enclosing scroller (with the same scrolling scope) and assume we didn't need
a node.

We can also simplify the "Stationary" code path to just ask about scrolling scopes.

The check for whether to use PDFPlugin happens in

will always be used when plugins are disabled and can use that information
to know whether to bypass CSP here in many cases. This will not relax
CSP or change behavior in other cases.

It would be ideal to check for an alternative PDF plugin in the case
where plugins are not disabled, but this information currently lives
in the UIProcess and is not sent to the WebProcess until after this
check. This patch will definitely fix Safari, where plugins are always disabled.

Source/WebCore:

Test: fast/multicol/newmulticol/zero-height-columns-oom-crash.html

Multicol sometimes computes <= 0 heights for the columns. For all those cases the code was adjusting them to 1px
values apparently to avoid creating an "infinite" amount of columns. However that adjustment was precisely causing
OOM situations in those cases where there was a relatively large amount of free space. In those cases the code was
creating dozens of thousands of 1px height columns (with all their associated structures) until we run out of memory.

Using zero heights in those cases seem sane because it's already being properly handled in the current code.

After the fix for ​https://bugs.webkit.org/show_bug.cgi?id=130844 in ​https://trac.webkit.org/changeset/260207/webkit a regression was found for
table cell selections through JavaScript. The previous fix was for an issue in the difference between how PositionIterator and Position calculated
if it was canonical (::isCandidate) in the cases where the renderer was a BR. Instead of only converging isCandidate for BR, this function in PositionIterator
was completely subsumed by just calling the implementation for Position. While there are many similarities, there are important differences, especially in the
table code, therefore PositionIterator::isCandidate is being reinstated, but with the convergence in the BR case only.
Also, moved the check added in ​http://webkit.org/b/211864 so it will cover cases that were missed due to this code being wrong while that fix was added.

this version seems to be somehow incompatible with python-secretstorage, which is required
for system keyring support on Linux. This bug is fixed in newer versions of python-keyring
that do not support python2, but we still support python2, so we cannot upgrade. I've tested
several versions of python-keyring and found that version 11.1.0 is the most recent version
that supports python2 and works properly on Linux, so let's stick with that until we are
ready to give up on python2.

[WTF] StringImpl::removeCharacters should be inlined

Reviewed by Saam Barati.

removeCharacters is used in WebCore's HTMLInputElement's critical path. And since String relatively has many elements (characters),
non-inlined StringImpl::removeCharacters causes significant number of indirect function calls of findMatch argument since it is
passed function pointer. We should make them templatized function to allow inlining of findMatch function to avoid repeated indirect calls.

Claim ownership of Canvas IOSurface backing in the WebProcess. If we don't do this, all
IOSurface memory gets attributed to the GPUProcess, making it a prime candidate for jetsam.
We need to attribute memory usage to the WebProcesses being served by the GPUProcess as much
as possible and this is a step in this direction.

Note that this patch currently only impacts Canvas IOSurface backing when "DOM Rendering in
GPUProcess" is disabled. When "DOM Rendering in GPUProcess" is enabled, we are not supposed
to use the IOSurface API in the WebProcess at all.

Patch by Michael Catanzaro <Michael Catanzaro> on 2021-01-19
Reviewed by Darin Adler.

We previously discovered that we need to either (a) manually zero the MessageInfo struct
with memcpy (accepted solution), or b) use attribute((packed)) to omit struct packing.
This seemed to fix our valgrind warnings when bmalloc was in use, but not when bmalloc is
disabled, as is good practice when valgrinding.

Turns out we need to zero (or pack) the AttachmentInfo struct as well. Let's go with zeroing
it, since all its members are trivially copyable, so that's safe to do.

For good measure, we'll implement a copy constructor and do so there as well. Do this for
MessageInfo too, to round out the original fix to MessageInfo.

Since AttachmentInfo and MessageInfo are no longer trivially-copyable, we now need to cast
them to void* when using memcpy in order to avoid -Wclass-memaccess warnings from GCC.

2. It uses the credential name to identify a credential that passed to the UI instead of the login choice object

as it turns out that the UI won't return the same object at all.

3. It delays to show the UI if the platform authenticator is involved given the platform authenticator might not contain

[WPE][GTK] Remove unnecessary child setup function from process launcher
​https://bugs.webkit.org/show_bug.cgi?id=220090

Patch by Michael Catanzaro <Michael Catanzaro> on 2021-01-19
Reviewed by Carlos Garcia Campos.

The process launcher currently uses a child setup function to close the server end of its
IPC socket. But this is totally unnecessary because this socket always uses CLOEXEC. So the
child setup function is redundant.

This is step one towards making Eclipse not crash when its UI process JVM is using a huge
amount of memory. In such conditions, fork() will fail due to OOM, but posix_spawn() will
still succeed. A child setup function forces GLib to use fork() instead of posix_spawn().
However, this commit is not sufficient to fix Eclipse, because GSubprocess itself sets its
own child setup function.

Optimize :hover/:active style invalidation for deep trees and descendant selectors
​https://bugs.webkit.org/show_bug.cgi?id=220711

Reviewed by Zalan Bujtas.

Hover and active states are flipped for the entire ancestor chain. We compute invalidation for each flipped
element separately. If the selectors are of form ':active .descendant' then each of these invalidations needs
to traverse the whole subtree, leading to O(n^{2) behavior.}

We really only need to traverse the descendants once, starting from the element closest to the root that changes state.

Compute the change root and pass the information to setActive/Hover.
