[JSC] JSFunction's m_executable / m_rareData should be merged
​https://bugs.webkit.org/show_bug.cgi?id=205554

Reviewed by Mark Lam.

This patch merges JSFunction::m_executable and JSFunction::m_rareData fields into one JSFunction::m_executableOrRareData field.
JSFunction is one of the most frequently allocated objects (e.g. it is common that anonymous JSFunction expression is used as a scope).
If we can save sizeof(JSFunction), we can get great savings in memory usage.

JSFunction::m_scope field is touched every time we execute this function. (op_get_scope, or obtaining JSGlobalObject for host functions).
On the other hand, m_executable field can be skipped if JSFunction call is cached by CallLinkInfo. So compared to JSFunction::m_scope,
this field is less frequently touched. So, we merge m_executable and m_rareData fields into one, m_executableOrRareData. When it holds
ExecutableBase*, we do nothing. But when we create FunctionRareData, we put ExecutableBase in FunctionRareData and store FunctionRareData
to JSFunction::m_executableOrRareData field with 0x1 flag.

This patch reduces sizeof(JSFunction) from 48 to 32.

[iOS] Layout tests sometimes throw an exception under checkForOutstandingCallbacks
​https://bugs.webkit.org/show_bug.cgi?id=205612
<rdar://problem/57789693>

Reviewed by Tim Horton.

On iOS, layout tests that synthesize HID events but end before WebKitTestRunnerApp finishes dequeueing and
handling those events occasionally cause the next test to crash with an Objective-C exception under
UIScriptControllerIOS::checkForOutstandingCallbacks. This happens when UIScriptContext is destroyed after a HID
marker event is dispatched, but before that HID marker event has been handled. (For clarity, the HID marker
event is a special vendor-defined event used by HIDEventGenerator to signify the end of a series of synthesized
HID events that were previously dispatched to the application).

This is typically fixed by ensuring that all iOS layout tests always wait for synthesized HID events to finish
before ending the test (i.e. by calling testRunner.notifyDone()). However, some tests that fall into this
category are imported: e.g. dom/events/document-level-touchmove-event-listener-passive-by-default.html in
web-platform-tests/, which does not wait for the swipe gesture to finish before completing. This current causes
us to dispatch the end of the gesture while the following test (dom/events/event-disabled-dynamic.html) begins.

While I wasn't able to trivially reproduce the exception locally, it was consistently reproducible by forcing a
50 ms sleep in -[HIDEventGenerator sendMarkerHIDEventWithCompletionBlock:], right before queueing the marker
event. This suggests that the crash is timing-dependent, and just seems to occasionally reproduce more
frequently in internal automation.

This test seems to be passing reliably in other engines (e.g. Chrome and Edge), so instead of trying to fix the
test to always wait for events to finish dispatching, we can address the issue by teaching WebKitTestRunner to
simply wait for outgoing marker events to finish dispatching before proceeding with the next test, rather than
crashing. This should not only fix the crash, but also address sporadic flakiness that may result from tests
that handle synthetic HID events that were dispatched by the previous test.

Rename checkForOutstandingCallbacks to waitForOutstandingCallbacks, and make it wait up to a second for the
application to finish handling any outgoing marker HID event. In the event that the timeout is hit, we still
throw an Objective-C exception to avoid beginning the next test in an unpredictable state.

[LFC][IFC] Keep the LineBreaker object around until after the line is closed.
​https://bugs.webkit.org/show_bug.cgi?id=205613
<rdar://problem/58222870>

Reviewed by Antti Koivisto.

In order to be able to point back to an earlier line wrap opportunity on the line e.g.
<div style="white-space: pre"><span style="white-space: normal">earlier_wrap opportunities</span> <span>can't_wrap_this content</span></div>
the LineBreaker class needs more context.
Currently (taking the example above), if the available space runs out somewhere around the second <span> we would just simply
overflow the line since the overflowing content has a style saying "do not wrap".
However the line has multiple earlier wrap opportunities inside the first <span>.
Since we construct a LineBreaker object for each continuous run

  1. [container start][earlier_wrap]
  2. [ ]
  3. [opportunities][container end]
  4. [ ]
  5. [container start][can't_wrap_this]
  6. [ ]
  7. [content][container end]

the LineBreaker does not have enough context to point back to the last line wrap opportunity (after run #3).

This patch is in preparation for supporting such content.

  1. Rename couple of functions and structs
  2. Move the LineBreaker construction to LineLayoutContext::layoutLine so that we can keep it around for multiple set of runs.

Refactor to simplify broadcasting to all media elements
​https://bugs.webkit.org/show_bug.cgi?id=205567

Reviewed by Eric Carlson.

Source/WebCore:

Over time, we have accumulated many different sets of all the media elements.
With the goal of being a bit abstract and not building too much behavior into
the Document object, we ended up with unnecessary complexity, and many sets
of all the HTMLMediaElement objects. This is a first cut at reducing that complexity.
At the same time, the refactoring makes all the iteration use a safe algorithm that
builds a vector of Ref<HTMLMediaElement>, safe even if the work done for each
media element calls out to arbitrary DOM operations.

Separately, this patch also includes some name changes that still say "atomic"

[LFC][Integration] Ensure layout boxes have expected display types
​https://bugs.webkit.org/show_bug.cgi?id=205606

Reviewed by Zalan Bujtas.

In some cases render tree may have display property values that don't match the renderer type. This is fine since the behavior is driven by the renderer.

  • Change PathElement's FloatPoint* that points to an array of 3 FloatPoints into a FloatPoint[3].
  • Change Path::strokeContains() to take a StrokeStyleApplier& instead of a StrokeStyleApplier*, since it assumes that the given StrokeStyleApplier is nonnull anyways.
  • Change Path::RoundedRectStrategy into an 8-bit enum class.
  • Other miscellaneous style fixes.

[LFC][IFC] Forward scan for soft wrap opportunities
​https://bugs.webkit.org/show_bug.cgi?id=205584
<rdar://problem/58188386>

Reviewed by Antti Koivisto.

This patch implements forward scanning to find wrap opportunities in inline content.
e.g <span></span>example<span><span></span> content</span>
When we reach "ex-" content, in order to figure out if it is at a wrap opportunity, we scan the content
forward until after we reach another inline content, in this case " " right before the "content" and
check if we can break the content between these 2 inline items.

isAtSoftWrapOpportunity: takes 2 (adjacent by skipping non-content inline items) and return true if there's
a soft wrap opportunity in between them.
LineBreaker::nextWrapOpportunity: returns the next wrap opportunity (either a soft wrap opportunity or a line break or the end of the content)

REGRESSION (r253282): Tests that use applyAutocorrection assert in UIScriptContext::requestUIScriptCompletion
​https://bugs.webkit.org/show_bug.cgi?id=205588
<rdar://problem/58109942>

Reviewed by Tim Horton.

The change made in r253282 intended to defer completing the async task prepared in
UIScriptController::applyAutocorrection until after the current runloop; however, it ended up keeping the
synchronous call to asyncTaskComplete. Fix this by removing this code, so that we instead wait for the
dispatch_async block to invoke asyncTaskComplete.

[LFC][IFC] LineBreaker should tell whether the line should receive no more content
​https://bugs.webkit.org/show_bug.cgi?id=205587
<rdar://problem/58188635>

Reviewed by Antti Koivisto.

LineBreaker returns IsEndOfLine::No when the current line should still be able to receive additional content.
This way we can start closing the line sooner (as opposed to start probing the subsequent content).
(Note that just because the current content overflows the line, it does not necessarily mean that the subsequent content
wraps to the next line.)

[Web Animations] REGRESSION: Changing the animation-duration of a CSS Animation may not resume it
​https://bugs.webkit.org/show_bug.cgi?id=205580
<rdar://problem/58127956>

Patch by Antoine Quint <Antoine Quint> on 2019-12-24
Reviewed by Dean Jackson.

Source/WebCore:

Test: webanimations/css-animation-dynamic-duration-change.html

Setting the animation-duration of an animation will transition the animation back into its idle state
and the "update animations and send events" procedure would remove that animation from the timeline.
It would also remove it from the map that would associate an animation with a given CSS Animation name
so that we would know whether an animation exists for a given animation name when one of the animation's
properties changed. Since that animation was (mistakenly) removed, we would fail to update its timing
and it would never be resumed. We now only update the CSS Animation name to animation map when styles
change.

(WebCore::AnimationTimeline::animationWasRemovedFromElement):

LayoutTests:

Add a new test that, by virtue of changing the animation-duration, transitions a CSS Animation from
idle, to running, back to idle and back to running. Prior to this change, the test would not perform
the final play state transition and the it would time out.

Service Worker doesn't terminate after a period of time when thread blocking
​https://bugs.webkit.org/show_bug.cgi?id=202992
<rdar://problem/56298596>

Reviewed by Chris Dumez.

Source/WebCore:

Whenever running a service worker task, running script or posting events (install, activate, message and fetch),
start a timer to check that the service worker is not spinning.
This is done by posting a task to service worker thread and hopping back to the main thread.
If this post/hop is done before the heartbeat timer is fired, the service worker is considered live.
Otherwise, the check is failed and the task is considered as failing.
The service worker will be terminated.
Timeout is 60 seconds by default and 1 second for test purposes.

Add settings to have short heartbeat timeout for testing purposes.
Add internals API to check whether a service worker is running.
