Web Inspector: popovers for function source code are malformed
https://bugs.webkit.org/show_bug.cgi?id=190859

Reviewed by Joseph Pecoraro.

Previously, the `WI.Popover` would be drawn twice: once when the
`WI.CodeMirrorTokenTrackingController` determines that the user has hovered on a function
token, and once again when the source for that function is formatted (after being retrieved).
In the case that the formatter is able to return the prettified source within a frame (or
two), the `WI.Popover` is still in the middle of animating to its new size, meaning that the
changes made by the formatted `update` will be overridden on the next rAF (creates a flash).

* UserInterface/Views/Popover.js:
(WI.Popover.prototype):
(WI.Popover.prototype._animateFrame.drawBackground):
(WI.Popover.prototype._drawBackground):
Add a member variable to make sure that there is only ever one rAF firing at a time.
Drive-by: rework the background code to only use one canvas.
* UserInterface/Views/SourceCodeTextEditor.js:
(WI.SourceCodeTextEditor.prototype._showPopoverForFunction.didGetDetails):
Don't show the `WI.Popover` until the formatter has finished prettifying the function's
source code, as otherwise there is brief moment that the popover appears and is empty.

[PSON] When navigating back and forth, 'about:blank' shows up in the back/forward list
https://bugs.webkit.org/show_bug.cgi?id=190846
<rdar://problem/45058938>

Reviewed by Antti Koivisto.

Source/WebCore:

When a page gets suspended after a process-swap, we navigate it to about:blank from inside the navigation
policy handler, by overriding the request URL. This normally works fine because we usually process-swap
on standard navigation. However, when we would process-swap on a back/forward navigation, we would end
up using the back/forward navigation load type to do the about:blank load. This would have repercussions
because history navigations update the current history item with the new URL (in this case 'about:blank').
To avoid the issue, switch to a standard load type whenever the client asks us to suspend and we load
'about:blank' as a result.

TextTrack cues should be updated more often than every 250ms.

Source/WebCore:

Test: media/track/track-cue-timing.html

TextTracks cues are recalculated on the playback timer, which fires at least every 250ms.
In addition to this timer, add a method to MediaPlayer to provide a task which will be
performed at a particular media time, and use this new method to request cues be updated
at the next interesting media time. The next interesting time would be either when the
soonest current cue will end, or when the next non-current cue will start, whichever is
earlier.

(Determining the "next non-current cue" requires new API on PODIntervalTree, as that class

[PSON] Add support for cross-site client-side redirects
https://bugs.webkit.org/show_bug.cgi?id=190806
<rdar://problem/45047344>

Reviewed by Geoffrey Garen.

Source/WebCore:

Add support for cross-site client-side redirects so that it swaps process and so that the back
forward list looks as expected. To support this, the following changes had to be done:
- The NavigationAction now provides additional information so that the WebProcess can communicate
  things about the client-side redirect to the UIProcess: lockHistory / lockBackForwardList and
  clientRedirectSourceForHistory.
- If the UIProcess decides to process-swap on a client-side redirect, we pass the client-side
  redirect information to the new WebContent process via LoadRequest struct. WebCore then takes
  care of setting things up using this information so that it recognizes that it is continuing
  a load that is a client side redirect.
- We also need to pass the current BackForwardListItem / HistoryItem to the new WebContent
  process so that the new process can truly lock history and keep updating the *current*
  HistoryItem, instead of creating a new HistoryItem.
- After a process swap, when we re-construct the WebFrameProxy for the main frame in the new
  process, we now set the frame's URL in the UIProcess to the URL it had before we swapped.
  Clients such as Safari, rely on the main frame's URL being the expected value (the last
  committed load URL) until the next load is committed when receiving didPerformRedirect
  calls. Because we are destroying the main frame on process-swapping, we were losing the
  last committed URL and Safari would hit assertions.

With this model, the willPerformClientRedirect IPC is still sent from the previous WebProcess
and the didPerformClientRedirect IPC is now sent by the new WebProcess. No change should be
observable from the client's point of view.

Source/WebCore:

Refactor code so that:
- All properties applied in StyleResolver::applyMatchedProperties are only applied once.
- Custom properties are only resolved once, in StyleResolver, when they are applied to the RenderStyle. They were previously resolved
  every time they were referenced, and again in RenderStyle.
- The font-size property is applied after its variable references, but before custom properties that depend on it.
- Cycles are detected at the same time as resolution.
- MutableStyleProperties' custom properties cannot be set from Javascript or WebKitLegacy if they do not parse for the property's type.
  If they contain var(--...) references, however, then they can be set because we cannot check if the references are valid from setProperty.
  This behaviour matches chrome, but is not documented in the spec.
- Custom property values have more explicit resolved/unresolved state.
- RenderStyle only ever holds resolved custom properties, and StyleResolver::CascadedProperties only holds unresolved properties.

2. DFG's compileNewArrayBuffer()'s HaveABadTime case was previously using the

   to use for creating an array buffer with.  This turns out to not be an issue

   the SlowPutArrayStorage structure anyway.  However, to be strictly correct,

[iOS] [Datalist] Can't pick datalist suggestions in a stock WKWebView
https://bugs.webkit.org/show_bug.cgi?id=190621
<rdar://problem/45310649>

Reviewed by Tim Horton.

Source/WebKit:

Fixes the bug by refactoring datalist suggestion information on iOS; currently, we override text suggestions on
_WKFormInputSession. This only works for a few internal clients (including Safari) that set a _WKInputDelegate
and also implement either -_webView:willStartInputSession: or -_webView:didStartInputSession:, which is
necessary in order to ensure that WebKit creates and maintains a form input session.

The two pieces of information that datalist code needs to vend to WKContentView are a list of UITextSuggestions
and a custom input view, which are both currently properties of _WKFormInputSession. This patch lifts these out
of the input session and makes them properties of WKContentView, which are used in
WebDataListSuggestionsDropdownIOS.

Test: fast/forms/datalist/datalist-textinput-suggestions-order.html

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

Add new properties to WKContentView: an input view for datalist suggestions, and a list of text suggestions.

(-[WKFormInputSession setSuggestions:]):
(-[WKContentView setupInteraction]):
(-[WKContentView cleanupInteraction]):
(-[WKContentView _endEditing]):

Pull out common logic when resigning first responder or tabbing to the next or previous text field into a new
helper. This helper notifies `_inputPeripheral`, `_formInputSession`, and `_dataListTextSuggestionsInputView`
when editing has ended; the input peripheral and suggestions input view use this chance to send the value of the
form control to the web process.

(-[WKContentView resignFirstResponderForWebView]):
(-[WKContentView inputView]):

If a custom input view is not set but we have an input view for a datalist's text suggestions, use the datalist
input view.

(-[WKContentView accessoryTab:]):
(-[WKContentView _stopAssistingNode]):

Clear datalist state on WKContentView.

(-[WKContentView dataListTextSuggestionsInputView]):
(-[WKContentView dataListTextSuggestions]):
(-[WKContentView setDataListTextSuggestionsInputView:]):
(-[WKContentView setDataListTextSuggestions:]):
(-[WKContentView updateTextSuggestionsForInputDelegate]):

Pull out logic for setting suggestions on UIKit's `inputDelegate` (i.e. UIKeyboardImpl). We now first consult
internally-vended text suggestions from _WKFormInputSession; if an internal client has not overridden our text
suggestions, then we simply use suggestions from the current datalist (if present).

simulate hitting the done button on the input view to dismiss the keyboard.

Source/WebKit:

This patch adds the following:
- The WebProcessPool now tells the WebsiteDataStore when a network process has
    been created.
- The WebsiteDataStore in turn tells the WebResourceLoadStatisticsStore when
    a network process has been created.
- The WebResourceLoadStatisticsStore makes sure to update the network processes
    with its cookie policy when it's notified that a network process has been
    created.

In addition, this patch changes the following:
- The ResourceLoadStatisticsMemoryStore no longer keeps track of which domains
    it has told the network process to block cookies for. The reason is that
    we cannot assume that there is only one network process so we should
    always send complete blocking data.
- The ResourceLoadStatisticsMemoryStore's functions for communicating cookie
    blocking state to the network process no longer take and forward the
    "clear first" parameter. This is because complete data is sent every time
    and thus the network process' set is always cleared on an update.
- Removes WebsiteDataStore::networkProcessDidCrash() and
    WebResourceLoadStatisticsStore::scheduleCookieBlockingStateReset() since
    the call site---WebProcessPool::ensureNetworkProcess()---now calls
    WebsiteDataStore::didCreateNetworkProcess() after a network process
    crash and the state sync for cookie blocking is triggered.

vmCall should check if we exit before emitting an OSR exit due to exceptions

(foo):

Source/JavaScriptCore:

The bug we were seeing is the MovHint removal phase would
eliminate a superfluous MovHint. This left a certain range
of nodes in a state where they would not be able to reconstruct
values for an OSR exit. This is OK, since this phase proved those
nodes don't exit. However, some of these nodes may use the vmCall
construct in FTLLower. vmCall used to unconditionally emit an
exception check after each call. However, if such a call happens
in the range of nodes where we can't exit, we would end up generating
an invalid exit (and running with validateFTLOSRExitLiveness flag
would find this issue).

This patch makes vmCall check to see if the node can exit before
emitting an exception check. A node not being able to exit implies
that it can't exit for exceptions, therefore, by definition, it can't
throw an exception.

Introduce CompletionHandler-based Async IPC messages with replies
https://bugs.webkit.org/show_bug.cgi?id=190746

Reviewed by Tim Horton.

Before this patch, to make an asynchronous IPC message with a reply you had to find two objects that
can talk to each other, make two new message types, send a generated identifier, keep track of that
identifier, make a HashMap somewhere to store the object waiting for the response, and hook it all up.
What a mess. No wonder people take shortcuts and make strange design decisions.

Now, you can just use a CompletionHandler and mark the reply as Async in *.messages.in.
I've adopted this with a message whose behavior is covered by the storage/indexeddb/modern/blob-cursor.html
layout test and many others. I intent to refine and further adopt this incrementally.

Add a GStreamer patch to avoid crashing when the run-time logging
level is TRACE. There was a missing null check which caused many
tests to crash.

LayoutTests:

Add failing test expectations for the GTK port. These tests are
not mirrored in the top-level TestExpectations file, since there
are no passing baselines for these tests there. The testing
infrastructure will report them as unexpected passing when they
are marked as [ Failure ] there, since their output matches the
failing output in this directory, and if you don't have an
expected test, then they fail as [ Missing ], and putting failing
baselines in the top-level cross-platform directory also seem
wrong...

The following two tests produce a dumpRenderTree output for
unknown reasons, and so they have been marked as Missing for now.

InlineLineBreaker takes the inline runs and applies the appropriate line breaking rules on them.
InlineRunProvider::Run objects ->

InlineRunProvider turns the following inline content ->

    <span>foo<span>bar</span></span>
    <img src="broken.jpg"><span>hello world</span>

into a set of runs ->

    <foobar><image box><hello>< ><world>

Note that a text run can overlap multiple inline elements. InlineRunProvider::Run only stores a reference to
the first inline element (continuous content can be accessed by iterating through the InlineContent ListHashSet).
These runs are the input to the line breaking algoritm.

[BigInt] Add ValueSub into DFG

Source/JavaScriptCore:

We are introducing in this patch a new node called ValueSub. This node
is necessary due to introduction of BigInt, making subtraction
operations result in non-Number values in some cases. In such case, ValueSub is
responsible to handle Untyped and BigInt operations.
In addition, we are also creating a speculative path when both
operands are BigInt. According to a simple BigInt subtraction microbenchmark,
this represents a speedup of ~1.2x faster.
