Merged r241626 - Crash in the hit testing code via HTMLPlugInElement::isReplacementObscured()
​https://bugs.webkit.org/show_bug.cgi?id=194691

Reviewed by Simon Fraser.

Source/WebCore:

The crash was caused by HTMLPlugInElement::isReplacementObscured updating the document
without updating the layout of ancestor documents (i.e. documents in which frame owner
elements appear) even though it hit-tests against the top-level document's RenderView.

Merged r241499 - Crash in DOMTimer::fired
​https://bugs.webkit.org/show_bug.cgi?id=194638

Reviewed by Brent Fulgham.

Source/WebCore:

This patch continues the saga of hunting down timer related crashes after r239814, r225985, r227934.

The crash was caused by the bug that we don't remove a DOMTimer from NestedTimersMap if a DOMTimer
is created & installed inside another DOMTimer's callback (via execute call in DOMTimer::fired).

Fixed the crash by using a Ref in NestedTimersMap. This will keep the timer alive until we exit
from DOMTimer::fired. Because DOMTimer::fired always calls stopTracking() which clears the map
we would not leak these DOM timers.

We could, alternatively, use WeakPtr in NestedTimersMap but that would unnecessarily increase the
size of DOMTimer for a very marginal benefit of DOMTimer objcets being deleted slightly earlier.
Deleting itself in DOMTimer's destructor involves more logic & house keeping in the timer code,
and is no longer the preferred approach when dealing with these classes of bugs in WebKit.

Merged r239814 - ThreadTimers should not store a raw pointer in its heap
​https://bugs.webkit.org/show_bug.cgi?id=192975
<rdar://problem/46893946>

Reviewed by Geoffrey Garen.

Right now, ThreadTimers's heap data structure stores a raw pointer to TimerBase. In order to harden the timer code,
this patch replaces it with ThreadTimerHeapItem, a newly introduced struct, which effectively acks like
WeakReference<TimerBase*> as the timer heap and TimerBase both store RefPtr to it, and TimerBase's destructor clears
the raw pointer back to TimerBase*.

This approach was taken instead of an out-right adoptation of WeakPtr since the heap data structure requires each node
in the heap to have a fixed "priority" yet WeakPtr with no valid pointer back to TimerBase would effectively lose its
"priority" thereby corrupting the heap data structure. That is, each item in the heap must remember its fire time and
insertion order even when the underlying TimerBase had gone away (this should never happen but the whole point of this
hardening is to make it work even in the precense of such a bug).

This patch also moves the heap index in TimerBase to ThreadTimerHeapItem, and replaces the pointer to the heap vector
in TimerBase by a reference to ThreadTimers in ThreadTimerHeapItem. Note that ThreadTimers is a per-thread singleton.

The correctness of this hardening was tested by commenting out the call to stop() and !isInHeap() assertion in
TimerBase::~TimerBase() as well as the !isInHeap() assertion in ThreadTimerHeapItem::clearTimer() and observing that
layout tests run successfully without hitting any debug assertions.

No new tests since there should be no observable behavior difference.

• WebCore.xcodeproj/project.pbxproj: Export ThreadTimers.h as a private header since it's now included in Timer.h
• platform/ThreadTimers.cpp:

(WebCore::ThreadTimers::updateSharedTimer): Delete ThreadTimerHeapItem's with nullptr TimerBase* (TimerBase had
already been deleted). This should only happen when TimerBase's destructor failed to remove itself from the timer heap,
which should never happen.
(WebCore::ThreadTimers::sharedTimerFiredInternal): Ditto. Also removed the redundant code which had removed the timer
from the heap since setNextFireTime does the removal already.

• platform/ThreadTimers.h: Outdented the whole file.

(WebCore::ThreadTimers::timerHeap): We use Vector<RefPtr<ThreadTimerHeapItem>> instead of Vector<Ref<~>> since Ref<~>
doesn't have a copy constructor which is used by std::push_heap.
(WebCore::ThreadTimerHeapItem): Added.
(WebCore::ThreadTimerHeapItem::hasTimer const): Added.
(WebCore::ThreadTimerHeapItem::setNotInHeap): Added. ThreadTimerHeapItem uses unsigned -1 as the single value which
signifies the item not being in the heap instead of all negative values as in the old code in TimerBase.

Merged r241289 - AXObjectCache::childrenChanged shouldn't update layout or style during another style recalc
​https://bugs.webkit.org/show_bug.cgi?id=182280
<rdar://problem/37018386>

Reviewed by Alan Bujtas.

Source/WebCore:

Remove the possibility that changing children calls back into updating layout by
handling children changes in a deferred manner.

This follows the same architecture as many other deferred changes, but also requires us to check deferred changes
in updateBackingStore, because things like aria-hidden changes won't trigger a layout, but will require us to update children.

A few tests had to be modified to no longer change the tree and then check the children immediately.

As intended by r240940, move installedPageOverlaysChanged to PageOverlayController.
Also, make it ignore isInWindow state; otherwise, if you install a overlay
and then come into window, nothing installs the root layer. There is no
need for this code to follow in-window state manually anymore since
the DrawingArea and RenderLayerCompositor just hook the layers up when needed.

Make some methods private, and make detachViewOverlayLayers only touch
*view* overlays, so that we don't detach the document-relative root
layer when you drop to having no view overlays. This maintains
existing behavior because nothing was calling PageOverlayController::detachViewOverlayLayers.

Now there are no callers of willDetachRootLayer, so remove it.

Tools:

Do a contains check instead of equals, because in debug builds we

[iOS] Callout menu overlaps in-page controls when editing a comment in github.com's issue tracker
​https://bugs.webkit.org/show_bug.cgi?id=194873
<rdar://problem/46701974>

Reviewed by Tim Horton.

Source/WebKit:

On the topic of supporting web-based rich text editors on iOS, one problematic area has always been handling
conflicts between platform UI (i.e., the system callout menu) and in-page text editing controls. This issue
comes up in websites that don't use the "hidden contenteditable" approach to rich text editing, but also show
additional controls in a toolbar or contextual menu above the selection. In these cases, what often happens is
that system controls overlap controls in the page.

Luckily, the iOS callout menu (i.e. the private UICalloutBar) is capable of presenting with a list of "evasion
rects" to avoid; if the callout bar would normally intersect with one of these rects, then a different
orientation that does not intersect with one of these rects is chosen instead. Currently, the only rect added
here by UIKit when presenting the callout menu is the bounding rect of the on-screen keyboard, but after
<rdar://problem/48128337>, we now have a generalized mechanism for offering additional evasion rects before
UIKit presents the callout menu.

This patch adopts the mechanism introduced in <rdar://problem/48128337>, and introduces a heuristic for
determining the approximate location of controls in the page which might overlap the callout menu. This
heuristic works by hit-testing for clickable (but non-editable) nodes above the bounds of the selection, which
are additionally not hit-tested by advancing outwards from any of the other edges of the selection bounds.
Additionally, any hit-tested nodes whose bounding rects are very large (relative to the content view size) are
ignored (this deals with scenarios where the body or a large container element has a click handler). We then add
the bounding rects of each of the nodes that fit this criteria to the list of rects for UIKit to avoid when
presenting the system callout menu.

The result is that WebKit will, by default, avoid overlapping anything that looks like controls in the page when
showing a callout menu in editable content. In practice, this fixes overlapping controls on most websites that
roll their own context menu or toolbar in their rich text editor.

Source/JavaScriptCore:

For each node that
(a) may or may not clobberExit depending on their arrayMode
(b) and get their arrayMode from profiling information in DFGBytecodeParser
(c) and can have their arrayMode refined by DFGFixupPhase,
We must make sure to be conservative in the DFGBytecodeParser and treat it as if it unconditionnally clobbered the exit.
Otherwise we will hit a validation failure after fixup if the next node was marked ExitValid and exits to the same semantic origin.

The list of nodes that fit (a) is:

• StringCharAt
• HasIndexProperty
• GetByVal
• PutByValDirect
• PutByVal
• PutByValAlias
• GetIndexedPropertyStorage

Out of these, the following also fit (b) and (c):

• HasIndexedProperty
• GetByVal
• PutByValDirect
• PutByVal

GetByVal already had "m_exitOK = false; GetByVal must be treated as if it clobbers exit state, since FixupPhase may make it generic."
So we just have to fix the other three the same way.

One test is created by adding delay to UniqueIDBDatabase::openBackingStore on the background thread to make sure
disconnection of web process happens before UniqueIDBDatabase::didOpenBackingStore, because didOpenBackingStore
may start a version change transaction and ask for identifier from the connection that is already gone.

B3ReduceStrength: missing peephole optimizations for binary operations
​https://bugs.webkit.org/show_bug.cgi?id=194252

Reviewed by Saam Barati.

Adds several sets of optimizations for BitAnd, BitOr and BitXor.
Using BitAnd distributivity over BitOr and BitXor:

Turn any of these (for Op == BitOr

Op == BitXor):

Op(BitAnd(x1, x2), BitAnd(x1, x3))
Op(BitAnd(x2, x1), BitAnd(x1, x3))
Op(BitAnd(x1, x2), BitAnd(x3, x1))
Op(BitAnd(x2, x1), BitAnd(x3, x1))

Into this: BitAnd(Op(x2, x3), x1)
And any of these:

Op(BitAnd(x1, x2), x1)
Op(BitAnd(x2, x1), x1)
Op(x1, BitAnd(x1, x2))
Op(x1, BitAnd(x2, x1))

Into this: BitAnd(Op(x2, x1), x1)
This second set is equivalent to doing x1 => BitAnd(x1, x1), and then applying the first set.

Using de Morgan laws (we represent not as BitXor with allOnes):

BitAnd(BitXor(x1, allOnes), BitXor(x2, allOnes)) => BitXor(BitOr(x1, x2), allOnes)
BitOr(BitXor(x1, allOnes), BitXor(x2, allOnes) => BitXor(BitAnd(x1, x2), allOnes)
BitOr(BitXor(x, allOnes), c) => BitXor(BitAnd(x, ~c), allOnes)
BitAnd(BitXor(x, allOnes), c) => BitXor(BitOr(x, ~c), allOnes)

The latter two are equivalent to doing c => BitXor(~c, allOnes), and then applying the former two.

All of these transformations either reduce the number of operations (which we always do when possible), or bring the expression closer to having:

• BitXor with all ones at the outermost
• then BitAnd
• then other BitXor
• then BitOr at the innermost.

These transformations that don't directly reduce the number of operations are still useful for normalization (helping things like CSE), and also can enable
more optimizations (for example BitXor with all ones can easily cancel each other once they are all at the outermost level).

[JSC] putNonEnumerable in JSWrapperMap is too costly
​https://bugs.webkit.org/show_bug.cgi?id=194935

Reviewed by Mark Lam.

When we convert Objective-C blocks to JS objects, we need to set up a corresponding function object correctly.
During this allocation, we call [JSValue defineProperty:descriptor] to connect a "prototype" object and "constructor" object.
The problem is that this API has a particularly costly implementation:

_context globalObject][@"Object"] invokeMethod:@"defineProperty" withArguments:@[ self, key, descriptor ;

This wraps each JS objects appear in this code with Objective-C wrapper. And we convert a NSDictionary to JSObject, which
has "writable", "enumerable", "configurable", "value" fields, and call the "defineProperty" JS function through Objective-C wrapper.
This allocates many Objective-C wrappers and JS objects for descriptors. Since JSC has a direct C++ API "defineOwnProperty", we should
bypass these Objective-C APIs and call JSC's code directly.

This patch changes putNonEnumerable implementation, from calling [JSValue defineProperty:descriptor] to calling JSC C++ code directly.
We do not change [JSValue defineProperty:descriptor] implementation for now because of two reasons. (1) This is not used in our benchmarks
except for this (converting an Objective-C block to a JS object) one path. And (2) even if we were to re-write [JSValue defineProperty:descriptor]
to be more optimized, we would still want to call the JSC C++ version of defineProperty directly here to avoid NSDictionary allocation for a descriptor.

[JSC] SmallStringsStorage is unnecessary
​https://bugs.webkit.org/show_bug.cgi?id=194939

Reviewed by Mark Lam.

SmallStrings hold common small JSStrings. Their underlying StringImpl is also held by SmallStringsStorage.
But it is duplicate since we can get StringImpl from small JSStrings. This patch removes SmallStringsStorage,
and get StringImpls from JSStrings if necessary.

We also add m_canAccessHeap flag to SmallStrings. At the time of VM destruction, JSStrings are destroyed when
VM's Heap is finalized. We must not touch JSStrings before VM's heap (and JSStrings in SmallStrings) is initialized,
and after VM's Heap is destroyed. We add this m_canAccessHeap flag to allow users to get StringImpl during the
this sensitive period. If m_canAccessHeap is false, we get StringImpl from AtomicStringImpl::add.

REGRESSION(PSON) Scroll position is sometimes not restored on history navigation
​https://bugs.webkit.org/show_bug.cgi?id=194924
<rdar://problem/48216125>

Reviewed by Geoffrey Garen.

Source/WebKit:

When process-swapping, we would create a new WebPage in the new process, which would
call restoreSessionInternal() to restore the HistoryItems based on the UIProcess's
backforward list. The issue is that this session restoring would send HistoryItem
updates back to the UIProcess. Without PSON, this would be unnecessary but harmless.
With PSON though, this may end up overwriting values set by the previous process,
such as the scroll position.

Address the issue by temporarily disabling the HistoryItem update notifications to
the UIProcess while restoring a session.

Input type "formatSetInlineTextDirection" is dispatched when changing paragraph-level text direction
​https://bugs.webkit.org/show_bug.cgi?id=194703
<rdar://problem/48111775>

Reviewed by Ryosuke Niwa.

Source/WebCore:

Currently, when changing text direction, WebKit always sends input events of type formatSetInlineTextDirection,
even when changing paragraph text direction. Instead, we should be emitting formatSetBlockTextDirection in this
scenario. This is problematic when using the context menus on macOS to change writing direction, since changing
"Selection Direction" is currently indistinguishable from changing "Paragraph Direction".

To fix this, we split EditAction::SetWritingDirection into EditAction::SetInlineWritingDirection and
EditAction::SetBlockWritingDirection, which emit inline and block text direction input events, respectively.

Cache CompactVariableMap::Handle instead of VariableEnvironment for UnlinkedFunctionExecutable
​https://bugs.webkit.org/show_bug.cgi?id=194706

Reviewed by Saam Barati.

In ​https://bugs.webkit.org/show_bug.cgi?id=194583 we started using a
CompactVariableMap::Handle instead of VariableEnvironment for
UnlinkedFunctionExecutables, but we were creating the full environment
to encode the executable in the bytecode cache. This patch changes it so
that we cache the handle instead of the environment. This avoids duplicating
the VariableEnvironment whenever we have to cache two handles that point
to the environment.

Hardcode Visual Viewports on everywhere except iOS WK1
​https://bugs.webkit.org/show_bug.cgi?id=194928

Reviewed by Zalan Bujtas.
Source/WebCore:

Remove the WK1 and WK2 preferences and MiniBrowser menu item for "visual viewports",
change the default value of the Setting to 'true', and hardcode WebView on iOS to

it off now.

Similarly, disable the "Visual Viewport API" on iOS WK1, since it makes no sense if
Visual Viewports are not enabled.

(WebCore::AccessibilityObject::focusedUIElement const): Use existing page
function to streamline.

• accessibility/AccessibilityRenderObject.cpp:

(WebCore::AccessibilityRenderObject::accessKey const): Use
attributeWithoutSynchronization for efficiency and consistency with other
code working with the accesskey attribute.

• dom/ContainerNode.cpp:

(WebCore::ContainerNode::childrenChanged): Added call to
invalidateAccessKeyCache, replacing old scheme tied to style recalculation.

• dom/DecodedDataDocumentParser.cpp:

(WebCore::DecodedDataDocumentParser::appendBytes): Update for name and return
type change of createDecoderIfNeeded to decoder.
(WebCore::DecodedDataDocumentParser::flush): Ditto.

• dom/Document.cpp:

(WebCore::Document::elementForAccessKey): Renamed from getElementForAccessKey
to match WebKit coding style. Changed to use unique_ptr instead of separate
boolean to keep track of map validity status.
(WebCore::Document::buildAccessKeyCache): Renamed from buildAccessKeyMap to
clarify that this is a cache. Changed to use composedTreeDescendants rather
than explicit calls to shadowRoot. Use add instead of set so that first element
in document order wins, instead of last element in document order. Updated
to make a new map in a new unique_ptr instead of populating a map.
(WebCore::Document::invalidateAccessKeyCacheSlowCase): Renamed from
invalidateAccessKeyMap, and left an inline part in the header so the fast case
of quickly checking for a null pointer can be inlined.
(WebCore::Document::doctype const): Use downcast instead of static_cast.
(WebCore::Document::scheduleStyleRecalc): Moved call to invalidateAccessKeyMap
from here to childrenChanged and accesskey attribute change handling.
(WebCore::Document::processFormatDetection): Set m_isTelephoneNumberParsingAllowed
directly since this is the only place that does it and we don't need to factor
that one line of code into a function.
(WebCore::Document::getOverrideStyle): Moved to header since it's just a stub
that always returns nullptr and can be inlined.
(WebCore::Document::setIsTelephoneNumberParsingAllowed): Deleted.
(WebCore::Document::ensureTemplateDocument): Removed nullptr frame argument to
the create function, since Document::create now always involves no frame.
(WebCore::Document::didAssociateFormControl): Changed argument type to a reference
and simplified the logic with a local variable.
(WebCore::Document::didAssociateFormControlsTimerFired): Simplified the null
checks and rearranged things so that m_associatedFormControls will always
get cleared even if the document is no longer associated with a page.

• dom/Document.h: Removed unnnecessary explicit values for enumerations (first

value is always zero, etc.) and formatted simple enumerations in a single line
for easier reading. Moved Document::create fucntion bodies out of line, removed
the frame argument from the simple "create with URL" overload and made the frame
argument for createNonRenderedPlaceholder be a reference rather than a pointer.
Renamed getElementByAccessKey to elementForAccessKey, invalidateAccessKeyMap to
invalidateAccessKeyCache, buildAccessKeyMap to buildAccessKeCache,
m_elementsByAccessKey to m_accessKeyCache and changed its type.
Removed bogus "DOM methods" comment, unused setParserFeature friend declaration,
setIsTelephoneNumberParsingAllowed function, and m_accessKeyMapValid flag.

• dom/Document.idl: Added comment highlighting that getOverrideStyle is just a

placeholder returning null.

• dom/Element.cpp:

(WebCore::Element::attributeChanged): Call invalidateAccessKeyCache when the
value of the accesskey attribute is changed. Also moved the class attribute code
so the attributes here are in alphabetical order (only class and id were out of
alphabetical order).

• dom/Node.cpp:

(WebCore::Node::isDescendantOrShadowDescendantOf const): Rewrote to no longer
use deprecatedShadowAncestorNode and used boolean operators to make it a
single line and easier to understand. Also added a FIXME since the
containsIncludingShadowDOM function is so similar, yet differently written.
(WebCore::Node::contains const): Rewrote as a single line to make this easier
to read and to *slightly* improve the speed in the "this == node" case.
(WebCore::Node::containsIncludingHostElements const): Use downcast.
(WebCore::Node::deprecatedShadowAncestorNode const): Deleted.

• dom/Node.h: Deleted now-unused deprecatedShadowAncestorNode.

• editing/ReplaceSelectionCommand.cpp:

(WebCore::ReplacementFragment::ReplacementFragment): Rewrote to use shadowHost
instead of deprecatedShadowAncestorNode.

• html/FormAssociatedElement.cpp:

(WebCore::FormAssociatedElement::resetFormOwner): Pass reference to
didAssociateFormControl.
(WebCore::FormAssociatedElement::formAttributeChanged): Ditto.

• html/HTMLAreaElement.cpp:

(WebCore::HTMLAreaElement::parseAttribute): Removed special case for accesskey
attribute, because we want to call the base class parseAttribute in that case.

• html/HTMLFormElement.cpp:

(WebCore::HTMLFormElement::insertedIntoAncestor): Pass reference to
didAssociateFormControl.

• html/HTMLSelectElement.cpp:

(WebCore::HTMLSelectElement::parseAttribute): Removed special case for accesskey
attribute with mysterious FIXME, because we want to call the base class
parseAttribute in that case. The old code had no effect before; the access key
logic would still find the attribute; if the goal is to ignore the attribute
for these elements we will need a different solution.

• html/HTMLTextAreaElement.cpp:

(WebCore::HTMLTextAreaElement::parseAttribute): Ditto.

• loader/DocumentLoader.cpp:

(WebCore::DocumentLoader::DocumentLoader): Removed code that was always passing
nullptr as the frame for the newly created DocumentWriter. It used m_frame, but
m_frame was always null.
(WebCore::DocumentLoader::attachToFrame): Pass reference to DocumentWriter::setFrame.

• loader/DocumentWriter.cpp:

(WebCore::DocumentWriter::DocumentWriter): Deleted. The old version set m_frame to
the passed in frame, which was always nullptr, and initialized some booleans and an
enumeration, which are now initialized in the class definition.
(WebCore::DocumentWriter::createDocument): Pass a reference for the frame.
(WebCore::DocumentWriter::begin): Updated now that State is an enum class.
(WebCore::DocumentWriter::decoder): Renamed from createDecoderIfNeeded and changed
to return a reference.
(WebCore::DocumentWriter::addData): Use RELEASE_ASSERT instead of if/CRASH and
updated now that State is an enum class.
(WebCore::DocumentWriter::insertDataSynchronously): Updated now that State is an
enum class.
(WebCore::DocumentWriter::end): Ditto.

• loader/DocumentWriter.h: Removed unneeded include and forward declaration.

Removed the frame pointer argument to the constructor, caller was always passing a
nullptr. Changed argument to setFrame to be a reference. Renamed createDecoderIfNeeded
to decoder and changed it to return a reference. Initialized m_frame,
m_hasReceivedSomeData, m_encodingWasChosenByUser, and m_state here so we don't need
to initialize them in a constructor. Renamed the enum from WriterState to State since
it's a member of DocumentWriter already, and made it an enum class rather than ending
each enumeration value with WritingState.

• page/DragController.cpp:

(WebCore::isEnabledColorInput): Removed boolean argument setToShadowAncestor. The
one caller that formerly passed true now calls the new hasEnabledColorInputAsShadowHost
function instead.
(WebCore::hasEnabledColorInputAsShadowHost): Added.
(WebCore::elementUnderMouse): Use shadowHost instead of deprecatedShadowAncestorNode.
Also added FIXME since it seems this should instead be using parentElementInComposedTree.
(WebCore::DragController::concludeEditDrag): Removed "false" argument to isEnabledColorInput.
(WebCore::DragController::canProcessDrag): Removed "true" argument to isEnabledColorInput
and added call to hasEnabledColorInputAsShadowHost. Also put the value of the node to drag
into a local variable to simplify code.
(WebCore::DragController::draggableElement const): Removed "false" argument to isEnabledColorInput.

Update JSScript SPI based on feedback
​https://bugs.webkit.org/show_bug.cgi?id=194517

Reviewed by Keith Miller.

This patch updates the JSScript SPI in the following ways:

• JSScript can now represent both modules and programs. This is a property

of the script determined during creation.

• JSScript now takes a sourceURL during construction. For modules, this acts

as the module identifier.

• JSScript now has SPI for writing the cache out to disk. We don't do this

automatically.

• JSScript will load the bytecode cache on creation if it exists.
• We retrofit these new requirements on the prior JSScript SPI that

we're going to remove as soon as we can: ​https://bugs.webkit.org/show_bug.cgi?id=194909.
Previous SPI assumes all JSScripts are modules. Previous SPI also assigns
a sourceURL to the JSScript based on what the module loader decided the
identifier should be. We'll remove this once we remove the old SPI.

This patch also adds SPI to JSContext to evaluate a JSScript. For modules,
this is like returning the result of doing dynamic import. For programs,
this does normal program evaluation.

This patch also fixes a bug in generateBytecode/generateModuleBytecode where
we would try to cache the bytecode even if recursivelyGenerateUnlinkedCodeBlock
returned null. E.g, if the script had a syntax error.

When writing tests, I also discovered that someone previously broke
testapi. This patch also fixes those failures. They were broken when
we switched to using a testapiScripts directory to hold our test .js
scripts.

Discard cached processes when clearing website data store
​https://bugs.webkit.org/show_bug.cgi?id=194894

Reviewed by Chris Dumez.

Source/WebKit:

Clear the process cache when clearing the website data store so that there is no way to infer
which site the user had visited by observing for which sites WebContent processes had been cached.

There is one sublty in WebsiteDataStore::removeData that we have to delay the clearing of
the web process cache until the next run loop because SuspendedPageProxy::~SuspendedPageProxy
invokes WebProcessProxy::maybeShutDown in the next run loop. We also have to disable the process
cache during this time as it would otherwise trigger the responsiveness check of WebContent process
can take arbitrarily long time.

Same Site Lax cookies are not sent with cross-site redirect from client-initiated load
​https://bugs.webkit.org/show_bug.cgi?id=194906
<rdar://problem/44305947>

Reviewed by Brent Fulgham.

Source/WebCore:

Ensure that a request for a top-level navigation is annotated as such regardless of whether
the request has a computed Same Site policy.

"New loads" initiated by a the client (Safari) either by API or a human either explicitly
typing a URL in the address bar or Command + clicking a hyperlink to open it in a new window/tab
are always considered Same Site. This is by definition from the spec. [1] as we aren't navigating
from an existing page. (Command + click should be thought of as a convenience to the user from
having to copy the hyperlink's URL, create a new window, and paste the URL into the address bar).
Currently the frame loader marks a request as a top-level navigation if and only if the request
does not have a pre-computed Same Site policy. However, "New loads" have a pre-computed Same Site
policy. So, these loads would never be marked as a top-level navigation by the frame loading code.
Therefore, if the "new load" turned out to be a cross-site redirect then WebKit would incorrectly
tell the networking stack that the load was a cross-site, non-top-level navigation, and per the
Same Site spec [2], the networking stack would not send Same Site Lax cookies. Instead,
WebKit should unconditionally ensure that requests are marked as a top-level navigation, if applicable.

[1] See Note for (1) in <​https://tools.ietf.org/html/draft-ietf-httpbis-rfc6265bis-02#section-5.2>

[PSON] Make sure hung processes are not kept alive by suspended pages or process caching

Reviewed by Geoffrey Garen.

After we construct a SuspendedPageProxy and before we send the IPC to the WebProcess to
ask it to suspend, start a 10 seconds timer. If the process does not answer the request
to suspend before the timer fires, we destroy the SuspendedPageProxy so that we do not
keep a hung process around.

For the WebProcessCache, we now call WebProcessProxy::isResponsive() on the process
before adding it to the cache. Internally, this relies on an IPC handshake with the
WebProcess. If the process is not responsive, we do not add it to the cache and we
shut it down. If it is responsive then we proceed normally with adding it to the
cache.

<rdar://problem/47924500>

Reviewed by Alex Christensen.

Source/WebKit:

[WKWebView _reloadWithoutContentBlockers] relies on a ReloadOption flag that is passed to WebCore
instead of using WebsitePolicies.contentBlockersEnabled flag. If the reload causes a process swap
due to PSON, then the new process does not know about this ReloadOption and fails to honor it.

Since the modern way to do this is WebsitePolicies, and since WebsitePolicies are properly
propagated cross-process in case of process swap, this patch updates _reloadWithoutContentBlockers
to set a flag on the Navigation which we use to later set the WebsitePolicies.contentBlockersEnabled
flag in WebPageProxy::receivedNavigationPolicyDecision().

Reviewed by Geoffrey Garen.

Source/WebKit:

The issue was caused by us mistakenly process-swapping for a same-site server side redirect.
The reason we were getting it wrong is because the logic in
WebProcessPool::processForNavigationInternal() was expecting page.process() to be the source
process and page.pageLoadState().url() to be the source URL. Those assumptions are incorrect
when a server-side redirect occurs in a provisional process. In such case, the source process
is the ProvisionalPageProxy's process and the source URL is the provisional URL, not the
committed one.

Crash in DOMWindowExtension::suspendForPageCache

Reviewed by Chris Dumez.

This is a speculative fix for a crash in DOMWindowExtension::suspendForPageCache.

We think it's possible for DOMWindowExtension::suspendForPageCache notifying the clients via
dispatchWillDisconnectDOMWindowExtensionFromGlobalObject to remove other DOMWindowExtension's.
Check that each DOMWindowProperty is still in m_properties before invoking suspendForPageCache
to avoid the crash.

REGRESSION (r238090): Toggling visibility on the <html> element can result in a blank web view
​https://bugs.webkit.org/show_bug.cgi?id=194827
rdar://problem/47620594

Reviewed by Antti Koivisto.

Source/WebCore:

Incremental compositing updates, added in rr238090, use repaints as a trigger for re-evaluating
layer configurations, since a repaint implies that a layer gains painted content. This is done
via the call to setNeedsCompositingConfigurationUpdate() in RenderLayerBacking::setContentsNeedDisplay{InRect}.
The RenderView's layer is opted out of this to avoid doing lots of redundant layer config recomputation
for the root. The configuration state that matters here is whether the layer contains painted content,
and therefore needs backing store; this is computed by RenderLayerBacking::isSimpleContainerCompositingLayer(),
and feeds into GraphicsLayer::drawsContent().

However, if <html> starts as "visibility:hidden" or "opacity:0", as some sites do to hide incremental loading,
then we'll fail to recompute 'drawsContent' for the root and leave the root with drawsContent=false, which
causes RenderLayerBacking::setContentsNeedDisplay{InRect} to short-circuit, and then we paint nothing.

Ironically, 'drawsContent' doesn't actually save any backing store for the root, since it has no affect on
the root tile caches; we always make tiles. So the simple fix here is to change RenderLayerBacking::isSimpleContainerCompositingLayer()
to always return false for the RenderView's layer (the root).

Testing this was tricky; ref testing doesn't work because we force repaint, and we normally skip
properties of the root in layer tree dumps to hide WK1/WK2 differences. Therefore I had to add
LAYER_TREE_INCLUDES_ROOT_LAYER_PROPERTIES and fix RenderLayerBacking::shouldDumpPropertyForLayer to
respect it.

Reviewed by Chris Dumez.

Source/WebCore:

With the new process model, WebProcess hits a case where it tries to send the "page loaded" notification before VoiceOver
had a chance to register for any notifications. This leads to those notifications being dropped (and thus this bug).

This change instead asks the UIProcess to send the notification, which we know VoiceOver has registered for, and can reliably
receive notifications.

It also sends the notification for "load failures," which to the VO users' perspective amounts to the same thing as a successful
page load.

Regression(PSON) Navigating quickly back and forth can lead to getting 'about:blank' in the backforward list
​https://bugs.webkit.org/show_bug.cgi?id=194717
<rdar://problem/47884404>

Reviewed by Brady Eidson.

Source/WebKit:

When the client does a history navigation, the UIProcess sends a WebPage::GoToBackForwardItem IPC to the
WebProcess and the WebProcess sends a WebPageProxy::BackForwardGoToItem IPC back to the UIProcess to
update the current item in the BackForwardList. This means that there is a slight delay between the
point a client requests a history navigation and the point where the BackForwardList's current item gets
update. This delay is pre-existing behavior and not new to PSON.

However, with PSON enabled, if we decide to process-swap for the history navigation, we'll tell the
previous (committed) process to ignore the load and we ask a new (provisional) process to do the history
navigation. When the previous process receives the request to ignore the history navigation, it restores
the History's current item to the one previous the navigation, which sends a WebPageProxy::GoToBackForwardItem
IPC to the UIProcess to update the BackForwardList as well. In parallel, the new process starts the
history navigation and also sends a WebPageProxy::GoToBackForwardItem to update the BackForwardList's
current item as well. We end up with a race between the 2 GoToBackForwardItem IPC messages coming from
the old and new process. If the old process's message loses the race, we end up with the wrong current
history item getting set in the UIProcess. Later, when we commit the provisional load and try to suspend
the previous page, we would save the SuspendedPage on the *wrong* BackForwardList item. If one tries to
load this BackForwardList item later, we'll use its SuspendedPage and try to unsuspend it. However,
because the PageCache entry is saved on another HistoryItem than the one getting loaded in the WebProcess
side, we attempt to do a regular load instead of a PageCache restore. We end up failing the load because
pages cannot trigger new loads while in page cache. Because the load fails, we end up loading the
initial empty document and this is how we end up with 'about:blank' in the back forward list.

To address the issue, update WebPageProxy::backForwardGoToItem() to ignore messages from the old/committed
WebProcess when there is a pending provisional load. If the committed processes starts a legit new
load, it would clear any existing pending provisional load before attempting the call backForwardGoToItem().
As a result, ignoring such messages from the old processes when there is a pending provisional load is
safe.

In the future, we should probably move more of the history / backForwardList management to the UIProcess
to avoid this sort of issues. This would be a much larger refactoring though so I am going with this
simpler fix that is easily cherry-pickable for now.

Source/WebCore:

Accessibility properties are complicated to fetch at all the points where we want to build and push nodes immediately.
Turning on AX often indirectly causes style recalc and layout. This is bad because we are often building nodes in the
first place due to a DOM node tree update (i.e., NodeInserted).

It turns out that DOM.getAccessibilityPropertiesForNode is called every time we display
the computed role in the Elements Tab > Nodes Sidebar > Accessibility Section. So it is not
necessary to collect this information in a problematic way when initially pushing the node, as
it will be updated anyway.

No new tests, no change in behavior.

After r240698 we could commit scrolling changes for a fixed node where the "viewportRectAtLastLayout" and the layer
position were mismatched; this happened when AsyncScrollingCoordinator::reconcileScrollingState() came back from the UI process
with an unstable update and set a new layoutViewport, then some other layout triggered a compositing tree update. During the tree
update, we'd update the fixed scrolling node with the new viewport, and an old layer position.

Fix by ensuring that we only update the geometry info for a scrolling tree node when we update layer geometry for the corresponding
layer.

After we construct a SuspendedPageProxy and before we send the IPC to the WebProcess to
ask it to suspend, start a 10 seconds timer. If the process does not answer the request
to suspend before the timer fires, we destroy the SuspendedPageProxy so that we do not
keep a hung process around.

For the WebProcessCache, we now call WebProcessProxy::isResponsive() on the process
before adding it to the cache. Internally, this relies on an IPC handshake with the
WebProcess. If the process is not responsive, we do not add it to the cache and we
shut it down. If it is responsive then we proceed normally with adding it to the
cache.

Add code to validate expected GC activity modelled by doesGC() against what the runtime encounters.
​https://bugs.webkit.org/show_bug.cgi?id=193938
<rdar://problem/47616277>

Reviewed by Michael Saboff, Saam Barati, and Robin Morisset.

In DFG::SpeculativeJIT::compile() and FTL::LowerDFGToB3::compileNode(), before
emitting code / B3IR for each DFG node, we emit a write to set Heap::m_expectDoesGC
to the value returned by doesGC() for that node. In the runtime (i.e. in allocateCell()
and functions that can resolve a rope), we assert that Heap::m_expectDoesGC is
true.

This validation code is currently only enabled for debug builds. It is disabled
for release builds by default, but it can easily be made to run on release builds
as well by forcing ENABLE_DFG_DOES_GC_VALIDATION to 1 in Heap.h.

To allow this validation code to run on release builds as well, the validation uses
RELEASE_ASSERT instead of ASSERT.

To ensure that Heap.h is #include'd for all files that needs to do this validation
(so that the validation code is accidentally disabled), we guard the validation
code with an if conditional on constexpr bool validateDFGDoesGC (instead of using
a #if ENABLE(DFG_DOES_GC_VALIDATION)). This way, if Heap.h isn't #include'd, the
validation code will fail to build (no silent failures).

Currently, all JSC tests and Layout tests should pass with this validation enabled
in debug builds. We'll only see new failures if there's a regression or if new
tests reveal a previously untested code path that has an undetected issue.

This is a speculative fix for a crash in DOMWindowExtension::suspendForPageCache.

We think it's possible for DOMWindowExtension::suspendForPageCache notifying the clients via
dispatchWillDisconnectDOMWindowExtensionFromGlobalObject to remove other DOMWindowExtension's.
Check that each DOMWindowProperty is still in m_properties before invoking suspendForPageCache

[bmalloc] bmalloc::Heap is allocated even though we use system malloc mode
​https://bugs.webkit.org/show_bug.cgi?id=194836

Reviewed by Mark Lam.

Previously, bmalloc::Heap holds DebugHeap, and delegates allocation and deallocation to debug heap.
However, bmalloc::Heap is large. We would like to avoid initialization of bmalloc::Heap under the
system malloc mode.

This patch extracts out DebugHeap from bmalloc::Heap, and logically puts this in a boundary of
bmalloc::api. bmalloc::api delegates allocation and deallocation to DebugHeap if DebugHeap is enabled.
Otherwise, using bmalloc's usual mechanism. The challenge is that we would like to keep bmalloc fast
path fast.

1. For IsoHeaps, we use the similar techniques done in Cache. If the debug mode is enabled, we always go to the slow path of the IsoHeap allocation, and keep IsoTLS::get() returning nullptr. In the slow path, we just fallback to the usual bmalloc::api::tryMalloc implementation. This is efficient because bmalloc continues using the fast path.

2. For the other APIs, like freeLargeVirtual, we just put DebugHeap check because this API itself takes fair amount of time. Then debug heap check does not matter.

REGRESSION: [ iOS ] Layout Test editing/input/ios/rtl-keyboard-input-on-focus.html is a Timeout
​https://bugs.webkit.org/show_bug.cgi?id=194601
<rdar://problem/48080316>

Reviewed by Tim Horton.

Following r241311, if a web view becomes first responder and is then moved offscreen (or obscured, hidden, or in
the case of WebKitTestRunner, its UIWindow loses its status as keyWindow), we end up holding on to the input
view update deferral token indefinitely, waiting for the current focused element to be blurred or refocused.

This also manifests other user-facing bugs, the most common of which is the keyboard occasionally remaining
onscreen after typing a URL in the unified field in MobileSafari and hitting Return, in the case where there is
no autofocused element on the page.

To fix this, when becoming the first responder, additionally install a callback to detect when the page is
finished handling the activity state change, and invalidate the input deferral token then. This retains the
behavior where calling -becomeFirstResponder on the web view while a different view is focused will keep the
keyboard stable, since the focused element message from the web process should be dispatched when handling the
activity state change within the web process.

Of course, the web process may not be responsive at all while the web view is still in the view hierarchy, in
which case we may still end up deferring input view updates indefinitely. In this case, we maintain a separate
watchdog timer with a short delay, after which we unconditionally invalidate the token.

<rdar://problem/47924500>

Reviewed by Alex Christensen.

Source/WebKit:

[WKWebView _reloadWithoutContentBlockers] relies on a ReloadOption flag that is passed to WebCore
instead of using WebsitePolicies.contentBlockersEnabled flag. If the reload causes a process swap
due to PSON, then the new process does not know about this ReloadOption and fails to honor it.

Since the modern way to do this is WebsitePolicies, and since WebsitePolicies are properly
propagated cross-process in case of process swap, this patch updates _reloadWithoutContentBlockers
to set a flag on the Navigation which we use to later set the WebsitePolicies.contentBlockersEnabled
flag in WebPageProxy::receivedNavigationPolicyDecision().

of new ones) using WebKitUserContentFilterStore; the associated WebKitUserContentFilter

The WebKitUserContentFilterStore public API is expressed in abstract terms of "saving"
filters into the store (which involves compiling the JSON source rule set); and "loading"
them back as main operations. This way we do not disclose to users of the API any detail
about compilation, nor how contents are laid out on disk, and the documentation explicitly
tells about only using the provided functions to manipulate the on-disk contents. This
way we allow ourselves some leeway if the implementation needs changing in the future.

Merge r241788 - REGRESSION (r238090): Toggling visibility on the <html> element can result in a blank web view
​https://bugs.webkit.org/show_bug.cgi?id=194827
rdar://problem/47620594

Reviewed by Antti Koivisto.

Source/WebCore:

Incremental compositing updates, added in rr238090, use repaints as a trigger for re-evaluating
layer configurations, since a repaint implies that a layer gains painted content. This is done
via the call to setNeedsCompositingConfigurationUpdate() in RenderLayerBacking::setContentsNeedDisplay{InRect}.
The RenderView's layer is opted out of this to avoid doing lots of redundant layer config recomputation
for the root. The configuration state that matters here is whether the layer contains painted content,
and therefore needs backing store; this is computed by RenderLayerBacking::isSimpleContainerCompositingLayer(),
and feeds into GraphicsLayer::drawsContent().

However, if <html> starts as "visibility:hidden" or "opacity:0", as some sites do to hide incremental loading,
then we'll fail to recompute 'drawsContent' for the root and leave the root with drawsContent=false, which
causes RenderLayerBacking::setContentsNeedDisplay{InRect} to short-circuit, and then we paint nothing.

Ironically, 'drawsContent' doesn't actually save any backing store for the root, since it has no affect on
the root tile caches; we always make tiles. So the simple fix here is to change RenderLayerBacking::isSimpleContainerCompositingLayer()
to always return false for the RenderView's layer (the root).

Testing this was tricky; ref testing doesn't work because we force repaint, and we normally skip
properties of the root in layer tree dumps to hide WK1/WK2 differences. Therefore I had to add
LAYER_TREE_INCLUDES_ROOT_LAYER_PROPERTIES and fix RenderLayerBacking::shouldDumpPropertyForLayer to
respect it.

​https://bugs.webkit.org/show_bug.cgi?id=194820

Reviewed by Geoffrey Garen.

Source/WebCore:

This release assertion was wrong. The invocation of PolicyChecker::checkNewWindowPolicy in FrameLoader
doesn’t require PolicyChecker's load type to be set in PolicyChecker because FrameLoader's
continueLoadAfterNewWindowPolicy invokes loadWithNavigationAction which sets the load type later,
and we don't rely on PolicyChecker's load type until then.

Fixed the crash by removing relese asserts before invoking checkNewWindowPolicy accordingly.

This patch reverts r241015 since it too was asserting that PolicyChecker's load type is set before
invoking checkNewWindowPolicy which is not the right assumption.

Reviewed by Saam Barati.

JSProxy is destructible one because we have JSWindowProxy which has ref counted object.
However, JavaScriptCore.framework's JSProxy for GlobalThis does not need to be destructible.
This is important since we need to separate Heap subspaces between destructible and non-destructible objects.
If we can put more and more objects in non-destructible status, we can get rid of low-usage MarkedBlock.
This patch adds JSNonDestructibleProxy, which is not destructible JSProxy. While it inherits JSDestructibleObject,
we can make the subclass still non-destructible thanks to Subspace mechanism. This drops one more low-usage MarkedBlock.

Merge r241768 - B3ReduceStrength::simplifyCFG() could do a lot more on each iteration
​https://bugs.webkit.org/show_bug.cgi?id=194475

Reviewed by Saam Barati.

B3ReduceStrength::simplifyCFG() does three optimizations (which I will call A, B and C):

• A makes any terminal that points to a block that is empty except for a jump point to that jump's target instead.
• B transforms any branch or switch that points to a single block into a jump
• C finds blocks ending with jumps, whose successor has a single predecessor, and inline that successor block in place of the jump

It currently is limited in the following way:

• A and C can only fire once per block per iteration
• B can create jumps that would trigger A, but they may not be seen until the next iteration

Both problems are mitigated by going through the blocks in post-order, so that when a block is optimized most of its successors have already been optimized.
In a sense it is the symmetric of the peephole optimizer that goes in pre-order so that when an instruction is optimized most of its children have already been optimized.

On JetStream2 it reduces the average number of iterations from 3.35 to 3.24.

Merge r241756 - [ARM] Fix crash with sampling profiler

Reviewed by Mark Lam.

Do not skip test since crash with sampling profiler is now fixed.

• stress/sampling-profiler-richards.js:

Source/JavaScriptCore:

sampling-profiler-richards.js was crashing with an enabled sampling profiler. add32
did not update the stack pointer in a single instruction. The src register was first
moved into the stack pointer, the immediate imm was added in a subsequent instruction.

This was problematic when a signal handler was invoked before applying the immediate,
when the stack pointer is still set to the temporary value. Avoid this by calculating src+imm in
a temporary register and then move it in one go into the stack pointer.

If the size of the grid container depends on the size of its tracks,
a percentage in fit-content() is indefinite. Without this patch, some
places treated this case as fit-content(0), which prevented the grid
container from growing enough to contain the max-content contribution
of its grid items.

This patch treats such fit-content() as minmax(auto, max-content),
but once the size of the grid container is known and it is laid out
"for real", then the percentage is definite and it's used.

JSTests:

(getProperties):
(getRandomProperty):
(i.catch):

Source/JavaScriptCore:

LazyClassStructure::get and LazyProperty::get functions do not allow compiler threads to call them. But for booleanPrototype, numberPrototype and symbolPrototype cases,
we would like to call them from compiler threads. We eagerly initialize them if VM::canUseJIT() is true, so that compiler threads can safely call LazyClassStructure::get
and LazyProperty::get for booleanPrototype, numberPrototype and symbolPrototype. But still assertion hits because the assertion requires that these functions need to be
called in non compiler threads. Calling getConcurrently() is not possible since symbolPrototype() function is called from both the main thread and compiler threads,
and we would like to lazily initialize SymbolPrototype object if it is called from the main thread, which can happen with non-JIT configuration.

This patch adds getInitializedOnMainThread(). Compiler threads can call it only when we know that the value is already initialized on the main thread. The main thread
can call it at anytime and this function lazily initializes the value. This is useful to make some of prototypes lazy with non-JIT configuration: With non-JIT configuration,
this function is always called from the main thread and it initializes the value lazily. Non-JIT configuration does not care about compiler threads since they do not exist.
With JIT configuration, we eagerly initialize them in JSGlobalObject::init so that getInitializedOnMainThread() always succeeds.

Basically, getInitializedOnMainThread() is get with different assertion location: While get always crashes if it is called from compiler threads, getInitializedOnMainThread()
crashes only when actual initialization happens on compiler threads. We do not merge them since get is still useful to find accidental initialization from compiler threads.

[WPE][GTK] Enable support for CONTENT_EXTENSIONS

Source/WebKit:

Adds new API to manage a collection of content extensions on disk (including compilation
of new ones) using WebKitUserContentFilterStore; the associated WebKitUserContentFilter
type (which represents a compiled content extension); and the functions needed to enable
and disable them for a given WebKitUserContentManager.

The WebKitUserContentFilterStore public API is expressed in abstract terms of "saving"
filters into the store (which involves compiling the JSON source rule set); and "loading"
them back as main operations. This way we do not disclose to users of the API any detail
about compilation, nor how contents are laid out on disk, and the documentation explicitly
tells about only using the provided functions to manipulate the on-disk contents. This
way we allow ourselves some leeway if the implementation needs changing in the future.

REGRESSION (r238090): Toggling visibility on the <html> element can result in a blank web view
​https://bugs.webkit.org/show_bug.cgi?id=194827
rdar://problem/47620594

Reviewed by Antti Koivisto.

Source/WebCore:

Incremental compositing updates, added in rr238090, use repaints as a trigger for re-evaluating
layer configurations, since a repaint implies that a layer gains painted content. This is done
via the call to setNeedsCompositingConfigurationUpdate() in RenderLayerBacking::setContentsNeedDisplay{InRect}.
The RenderView's layer is opted out of this to avoid doing lots of redundant layer config recomputation
for the root. The configuration state that matters here is whether the layer contains painted content,
and therefore needs backing store; this is computed by RenderLayerBacking::isSimpleContainerCompositingLayer(),
and feeds into GraphicsLayer::drawsContent().

However, if <html> starts as "visibility:hidden" or "opacity:0", as some sites do to hide incremental loading,
then we'll fail to recompute 'drawsContent' for the root and leave the root with drawsContent=false, which
causes RenderLayerBacking::setContentsNeedDisplay{InRect} to short-circuit, and then we paint nothing.

Ironically, 'drawsContent' doesn't actually save any backing store for the root, since it has no affect on
the root tile caches; we always make tiles. So the simple fix here is to change RenderLayerBacking::isSimpleContainerCompositingLayer()
to always return false for the RenderView's layer (the root).

Testing this was tricky; ref testing doesn't work because we force repaint, and we normally skip
properties of the root in layer tree dumps to hide WK1/WK2 differences. Therefore I had to add
LAYER_TREE_INCLUDES_ROOT_LAYER_PROPERTIES and fix RenderLayerBacking::shouldDumpPropertyForLayer to
respect it.

REGRESSION(r240909): Release assertion in FrameLoader::loadPostRequest when opening new window
​https://bugs.webkit.org/show_bug.cgi?id=194820

Reviewed by Geoffrey Garen.

Source/WebCore:

This release assertion was wrong. The invocation of PolicyChecker::checkNewWindowPolicy in FrameLoader
doesn’t require PolicyChecker's load type to be set in PolicyChecker because FrameLoader's
continueLoadAfterNewWindowPolicy invokes loadWithNavigationAction which sets the load type later,
and we don't rely on PolicyChecker's load type until then.

Fixed the crash by removing relese asserts before invoking checkNewWindowPolicy accordingly.

This patch reverts r241015 since it too was asserting that PolicyChecker's load type is set before
invoking checkNewWindowPolicy which is not the right assumption.

[JSC] Introduce JSNonDestructibleProxy for JavaScriptCore.framework's GlobalThis

Reviewed by Saam Barati.

JSProxy is destructible one because we have JSWindowProxy which has ref counted object.
However, JavaScriptCore.framework's JSProxy for GlobalThis does not need to be destructible.
This is important since we need to separate Heap subspaces between destructible and non-destructible objects.
If we can put more and more objects in non-destructible status, we can get rid of low-usage MarkedBlock.
This patch adds JSNonDestructibleProxy, which is not destructible JSProxy. While it inherits JSDestructibleObject,
we can make the subclass still non-destructible thanks to Subspace mechanism. This drops one more low-usage MarkedBlock.

B3ReduceStrength::simplifyCFG() could do a lot more on each iteration
​https://bugs.webkit.org/show_bug.cgi?id=194475

Reviewed by Saam Barati.

B3ReduceStrength::simplifyCFG() does three optimizations (which I will call A, B and C):

• A makes any terminal that points to a block that is empty except for a jump point to that jump's target instead.
• B transforms any branch or switch that points to a single block into a jump
• C finds blocks ending with jumps, whose successor has a single predecessor, and inline that successor block in place of the jump

It currently is limited in the following way:

• A and C can only fire once per block per iteration
• B can create jumps that would trigger A, but they may not be seen until the next iteration

Both problems are mitigated by going through the blocks in post-order, so that when a block is optimized most of its successors have already been optimized.
In a sense it is the symmetric of the peephole optimizer that goes in pre-order so that when an instruction is optimized most of its children have already been optimized.

On JetStream2 it reduces the average number of iterations from 3.35 to 3.24.

The issue was caused by us mistakenly process-swapping for a same-site server side redirect.
The reason we were getting it wrong is because the logic in

when a server-side redirect occurs in a provisional process. In such case, the source process
is the ProvisionalPageProxy's process and the source URL is the provisional URL, not the

Source/WebCore:

With the new process model, WebProcess hits a case where it tries to send the "page loaded" notification before VoiceOver
had a chance to register for any notifications. This leads to those notifications being dropped (and thus this bug).

This change instead asks the UIProcess to send the notification, which we know VoiceOver has registered for, and can reliably
receive notifications.

It also sends the notification for "load failures," which to the VO users' perspective amounts to the same thing as a successful
page load.

Regression(PSON) Navigating quickly back and forth can lead to getting 'about:blank' in the backforward list
​https://bugs.webkit.org/show_bug.cgi?id=194717
<rdar://problem/47884404>

Reviewed by Brady Eidson.

Source/WebKit:

When the client does a history navigation, the UIProcess sends a WebPage::GoToBackForwardItem IPC to the
WebProcess and the WebProcess sends a WebPageProxy::BackForwardGoToItem IPC back to the UIProcess to
update the current item in the BackForwardList. This means that there is a slight delay between the
point a client requests a history navigation and the point where the BackForwardList's current item gets
update. This delay is pre-existing behavior and not new to PSON.

However, with PSON enabled, if we decide to process-swap for the history navigation, we'll tell the
previous (committed) process to ignore the load and we ask a new (provisional) process to do the history
navigation. When the previous process receives the request to ignore the history navigation, it restores
the History's current item to the one previous the navigation, which sends a WebPageProxy::GoToBackForwardItem
IPC to the UIProcess to update the BackForwardList as well. In parallel, the new process starts the
history navigation and also sends a WebPageProxy::GoToBackForwardItem to update the BackForwardList's
current item as well. We end up with a race between the 2 GoToBackForwardItem IPC messages coming from
the old and new process. If the old process's message loses the race, we end up with the wrong current
history item getting set in the UIProcess. Later, when we commit the provisional load and try to suspend
the previous page, we would save the SuspendedPage on the *wrong* BackForwardList item. If one tries to
load this BackForwardList item later, we'll use its SuspendedPage and try to unsuspend it. However,
because the PageCache entry is saved on another HistoryItem than the one getting loaded in the WebProcess
side, we attempt to do a regular load instead of a PageCache restore. We end up failing the load because
pages cannot trigger new loads while in page cache. Because the load fails, we end up loading the
initial empty document and this is how we end up with 'about:blank' in the back forward list.

To address the issue, update WebPageProxy::backForwardGoToItem() to ignore messages from the old/committed
WebProcess when there is a pending provisional load. If the committed processes starts a legit new
load, it would clear any existing pending provisional load before attempting the call backForwardGoToItem().
As a result, ignoring such messages from the old processes when there is a pending provisional load is
safe.

In the future, we should probably move more of the history / backForwardList management to the UIProcess
to avoid this sort of issues. This would be a much larger refactoring though so I am going with this
simpler fix that is easily cherry-pickable for now.

[PSON] Introduce a WebContent Process cache
​https://bugs.webkit.org/show_bug.cgi?id=194594
<rdar://problem/46793397>

Reviewed by Geoff Garen.

Source/WebCore:

Update localizable strings.

• en.lproj/Localizable.strings:

Source/WebKit:

Introduce a WebContent Process cache to reduce the number of process launches when
process swap on navigation is enabled, and to reduce the power cost of the feature.

If a WebProcess loaded pages from a single registrable domain then it is eligible
for the cache. When process-swapping on navigation to a new registrable domain, we
now attempt to retrieve a process from the cache for the domain in question instead
of always launching a new one.

The WebProcess cache currently has the following attributes:

• It may contains 4 processes per GB of RAM the machine has, up to 30 processes.
• WebProcesses automatically get evicted from the cache after 30 minutes.
• If the application is no longer the active app, then the cache will get cleared after 5 minutes.
• WebProcesses that are in the cache are reported as "(Cached)" in Activity Monitor.

The WebProcess cache is currently disabled by default and can by enabled by the
client via SPI.

• Shared/WebBackForwardListItem.cpp: (WebKit::WebBackForwardListItem::WebBackForwardListItem):
• Shared/WebBackForwardListItem.h: (WebKit::WebBackForwardListItem::lastProcessIdentifier const): (WebKit::WebBackForwardListItem::setLastProcessIdentifier): Add new lastProcessIdentifier data member that reflects which process this item was last loaded in. It is normally identical to the identifier of the process that created the item but it gets overriden in case of cross-site client-side redirect, since a new process takes over the item in this case.

• Sources.txt: Add new source file.

• UIProcess/API/APIProcessPoolConfiguration.cpp: (API::ProcessPoolConfiguration::copy):

• UIProcess/API/Cocoa/_WKProcessPoolConfiguration.mm: (-[_WKProcessPoolConfiguration setUsesWebProcessCache:]): (-[_WKProcessPoolConfiguration usesWebProcessCache]): Add new SPI to enable the WebProcess cache.

• UIProcess/API/Cocoa/WKProcessPool.mm: (-[WKProcessPool _webProcessCountIgnoringPrewarmedAndCached]):
• UIProcess/API/Cocoa/WKProcessPoolPrivate.h: Add new SPI for testing which returns the number of WebProcesses ignoring both prewarmed and cached ones.

• UIProcess/Cocoa/WebProcessPoolCocoa.mm: (WebKit::WebProcessPool::registerNotificationObservers): (WebKit::WebProcessPool::unregisterNotificationObservers): Add application active state observers as the WebProcess cache gets cleared when the application resigns active state for more than 5 minutes.

• UIProcess/ProvisionalPageProxy.cpp: (WebKit::ProvisionalPageProxy::loadRequest): When doing a load in a new process with the BackForwardList locked (i.e. client-side redirect), make sure we update the last process identifier for the BackForwardListItem. This is important because the logic in WebProcessPool::processForNavigation() relies on this identifier to select which process to do the history navigation into, and we want to do the load in the post-redirect process, not the pre-redirect one.

• UIProcess/WebPageProxy.cpp: (WebKit::WebPageProxy::didStartProvisionalLoadForFrameShared): Tell the WebProcess whenever a main frame provisional load is started, providing the URL.

(WebKit::WebProcessCache::WebProcessCache): (WebKit::WebProcessCache::addProcess): (WebKit::WebProcessCache::takeProcess): (WebKit::WebProcessCache::updateMaximumSize): (WebKit::WebProcessCache::clear): (WebKit::WebProcessCache::setApplicationIsActive): (WebKit::WebProcessCache::evictProcess): (WebKit::WebProcessCache::CachedProcess::CachedProcess): (WebKit::WebProcessCache::CachedProcess::~CachedProcess): (WebKit::WebProcessCache::CachedProcess::takeProcess): (WebKit::WebProcessCache::CachedProcess::evictionTimerFired):
• UIProcess/WebProcessCache.h: Added. (WebKit::WebProcessCache::maximumSize): (WebKit::WebProcessCache::size const): (WebKit::WebProcessCache::CachedProcess::process): Add process cache implementation.

• UIProcess/WebProcessPool.cpp: (WebKit::m_webProcessCache): WebProcessCache is stored on the WebProcessPool via m_webProcessCache data member.

(WebKit::WebProcessPool::~WebProcessPool):
Clear the WebProcess cache in the destructor.

(WebKit::WebProcessPool::setApplicationIsActive):
Notify the WebProcessCache whenever the application's active state changes.

(WebKit::WebProcessPool::createWebPage):
If the state of PSON changes via the experimental features menu, dynamically
update the WebProcessCache's size. This is needed because the cache is disabled
when PSON is disabled.

(WebKit::WebProcessPool::handleMemoryPressureWarning):
Clear the WebProcess cache on memory pressure.

(WebKit::WebProcessPool::processForNavigationInternal):
Query the WebProcessCache before attempting to create a new WebProcess for a cross-site
navigation.

(WebKit::WebProcessPool::findReusableSuspendedPageProcess):
This logic was split out of processForNavigationInternal() to reduce the size
of the method.

• UIProcess/WebProcessPool.h:
• UIProcess/WebProcessProxy.cpp: (WebKit::WebProcessProxy::setIsInProcessCache): Update the isInProcessCache flag on the WebProcessProxy and send an IPC to the WebContent process so that it can update its name in Activity Monitor. We also need to stop holding a strong reference to the WebProcessPool whenever the process is in the cache, similarly to what we do for pre-warmed processes, given that such processes should not keep the process pool alive.

(WebKit::WebProcessProxy::addExistingWebPage):
Assert that we never try to add a page to a cached process, it should be taken out of the
cache before use.

(WebKit::WebProcessProxy::hasProvisionalPageWithID const):
(WebKit::WebProcessProxy::isAllowedToUpdateBackForwardItem const):
(WebKit::WebProcessProxy::updateBackForwardItem):
In case of client-side redirects, the previous process would sometimes send an IPC causing
the UIProcess' backforward list item to get updated with the pre-redirect URL after we've
already redirected. This previously would be unlikely to occur because we do not suspend
client-redirect pages and their process would normally exit before getting a chance to send
the IPC. However, with the process cache, the bug became obvious as the process would stay
alive and send up the "bad" IPC. To address the issue, we now only let the IPC update the
item if the item's page is (still) associated with the process. In the future, we may want
to update the IPC so that it gets sent to the WebPageProxy instead of the WebProcessProxy.

(WebKit::WebProcessProxy::processDidTerminateOrFailedToLaunch):
If a cached WebProcess crashes, remove it from the cache so that we do not attempt to use
it for a load later.

(WebKit::WebProcessProxy::canBeAddedToWebProcessCache const):
Only cache WebProcesses that have loaded a single registrable domain. Also prevent caching
for service worker and inspector processes.

(WebKit::WebProcessProxy::maybeShutDown):
If the process is cacheable, add it to the cache instead of shutting it down right away.

(WebKit::WebProcessProxy::canTerminateAuxiliaryProcess):
Make sure we do not attempt to terminate a processes that is in the cache.

(WebKit::WebProcessProxy::didStartProvisionalLoadForMainFrame):
Whenever a main frame provisional load starts, make sure we update the process's associated
registrable domain. nullopt indicates that there is no associated domain yet. Null string
indicates that the process is associated with several registrable domain and is therefore
not eligible for caching.
