Add some randomness into the StructureID.
https://bugs.webkit.org/show_bug.cgi?id=194989
<rdar://problem/47975563>

Reviewed by Yusuke Suzuki.

On 64-bit, the StructureID will now be encoded as:

----------------------------------------------------------------
| 1 Nuke Bit | 24 StructureIDTable index bits | 7 entropy bits |
----------------------------------------------------------------

The entropy bits are chosen at random and assigned when a StructureID is
allocated.

Instead of Structure pointers, the StructureIDTable will now contain encodedStructureBits, which is encoded as such:

----------------------------------------------------------------
| 7 entropy bits | 57 structure pointer bits |
----------------------------------------------------------------

The entropy bits here are the same 7 bits used in the encoding of the
StructureID for this structure entry in the StructureIDTable.

Retrieval of the structure pointer given a StructureID is now computed as follows:

index = structureID >> 7; with arithmetic shift.
encodedStructureBits = structureIDTable[index];
structure = encodedStructureBits ^{(structureID << 57);}

We use an arithmetic shift for the right shift because that will preserve
the nuke bit in the high bit of the index if the StructureID was not
decontaminated before use as expected.

Remove unused function loadArgumentWithSpecificClass() in SpecializedThunkJIT.

Define StructureIDTable::m_size to be the number of allocated StructureIDs instead of always being the same as m_capacity.

Change StructureIDTable::s_unusedID's value to 0.

Its previous value of unusedPointer i.e. 0xd1e7beef, does not make sense for
StructureID on 64-bit. Also, there was never any code that initializes unused
IDs to the s_unusedID. The only meaningful value for s_unusedID is 0, which
is the ID we'll get when the freelist is empty, prompting a resize of the
structureIDTable.

This patch appears to be perf neutral on JetStream 2 run via the cli on a
11" MacBook Air, 13" MacBook Pro, iPhone 6S, and iPhone XR.

[JSC] Revert r226885 to make SlotVisitor creation lazy
https://bugs.webkit.org/show_bug.cgi?id=195013

Reviewed by Saam Barati.

We once changed SlotVisitor creation apriori to drop the lock. Also, it turns out that SlotVisitor is memory-consuming.
We should defer SlotVisitor creation until it is actually required. This patch reverts r226885. Even with this patch,
we still hold many SlotVisitors after we execute many parallel markers at least once. But recovering the feature of
dynamically allocating SlotVisitors helps further memory optimizations in this area.

scalableNativeWebpageParameters() is not preserved on new page navigation.

testb3 and testair should test O0/O1/O2

Reviewed by Mark Lam.

This patch makes it so that we run all tests in testair and testb3
in O0, O1, and O2. However, some tests are invalid for O0 and O1.
This patch makes it so we only run those tests in O2. These are
often tests that assert certain optimizations have occurred. There
are also a class of tests that rely on using patchpoints to stress
the register allocator into only a single valid allocation. The
O0, and sometimes O1, register allocators are not always good enough
to allocate such programs. To make these valid allocators to use, we rely
on the FTL and Wasm to not emit such patchpoints.

[JSC] stress/function-constructor-reading-from-global-lexical-environment.js fails in 32bit arch
https://bugs.webkit.org/show_bug.cgi?id=195030
<rdar://problem/48385088>

Reviewed by Saam Barati.

While LLInt64 has checkTDZInGlobalPutToScopeIfNecessary for op_put_to_scope GlobalLexicalVar to check the value in the variable slot is not empty,
this check is missing in LLInt32_64. Previously, this check was subsumed accidentally by the WatchpointSet check in GlobalLexicalVar in notifyWrite:
because no "put" attempt succeeds here, the status WatchpointSet was ClearWatchpoint, we always go to the slow path, and we always throw the TDZ error
before configuring the WatchpointSet in the slow path. But after r241862, WatchpointSet is not used under non-JIT configuration. This skips WatchpointSet
check and LLInt32_64 starts failing tests because of lack of checkTDZInGlobalPutToScopeIfNecessary. This patch adds checkTDZInGlobalPutToScopeIfNecessary
in LLInt32_64 too. This patch fixes the following four failing tests.

[JSC] Make Intl fields lazily-allocated

This patch makes the following memory footprint optimization in IntlObject.

Make IntlObject fields including Intl.Collator lazily-allocated because we already removed direct references from JS builtins to these constructors (@Collator etc.).

Move LazyProperty<IntlObject, Structure> structures from IntlObject to JSGlobalObject. This makes sizeof(IntlObject) the same to the other ones of usual runtime Objects, and drop one MarkedBlock.

[iOS] Adjust initial scale zooming heuristics when changing view scale
https://bugs.webkit.org/show_bug.cgi?id=194995

Reviewed by Tim Horton.

Source/WebKit:

Currently, we only zoom to the new initial scale iff we're exactly at initial scale before changing the view
scale. This was done so that if a user zoomed in really far and then increased the view scale, we wouldn't end
up zooming out as a result. However, this leads to confusing behavior in the case where the user has manually
changed the zoom scale to something close to (but not exactly) initial scale, and then attempts to zoom in
further using view scale. In this case, we'll end up keeping page scale the same, so it looks like nothing is
happening.

To fix this, we tweak our heuristics for determining whether to jump to initial scale; if the view scale is
increasing and the new initial scale is greater than the current scale, zoom to initial scale. Likewise, if the
view scale is decreasing and the new initial scale is less than the current scale, zoom to initial scale.

Introduce and adopt new class RegistrableDomain for eTLD+1
https://bugs.webkit.org/show_bug.cgi?id=194791
<rdar://problem/48179240>

Reviewed by Alex Christensen, Fujii Hironori, and Brent Fulgham.

Source/WebCore:

A new API test was added. Plenty of existing layout tests under
http/tests/resourceLoadStatistics/ and http/tests/storageAccess/ test the code.

This patch introduces and adopts a new class called WebCore::RegistrableDomain
which represents a domain's eTLD+1 (effective top level domain plus one) and is
the basis for the term "site," as in same-site. Other popular names include
high-level domain, primary domain, and top privately controlled/owned domain.
Effective top level domains are enumerated on the Public Suffix List
(https://publicsuffix.org).

This class just uses the full domain for when the Public Suffix List cannot help
finding the registrable domain and for WebKit ports that haven't enabled
PUBLIC_SUFFIX_LIST. It also uses the string "nullOrigin" as a representation
for the null or unique origin (this matches how these origins were handled
before).

The implementation is a wrapper around a String and the functions and class
members that now make use of this new class used to handle regular String
objects which didn't help much in terms of type safety or guarantees that the
string had already been converted to an eTLD+1.

We've at least two bad bugs in the Storage Access API because of confusion
between a URL's eTLD+1 and its host. The usage of WebCore::RegistrableDomain
will prohibit such bugs in the future.

Partitioning in WebKit also uses eTLD+1 to a large extent. I plan to adopt
WebCore::RegistrableDomain for partitioning in a later patch.

This patch also enhances parameter naming by:

Removing parts that refer to "primary" as in primaryDomain.
Replacing references to "TopPrivatelyControlledDomain" with "RegistrableDomain."
Replacing references to "TopPrivatelyOwnedDomain" with "RegistrableDomain."
Using the term "domain" consistently instead of e.g. "host."

Avoid hashing CompactVariableEnvironment when decoding CompactVariableMap::Handle
https://bugs.webkit.org/show_bug.cgi?id=194937

Hashing the CompactVariableEnvironment is expensive and we could avoid it

a pointer to the same CompactVariableEnvironment will hash the same.

Split iOS tests for hit testing in iframes
https://bugs.webkit.org/show_bug.cgi?id=195003

This patch splits hit-testing-iframe.html into smaller tests to faciliate
debugging and handling of test expectations. It also adds a new test
for programmatic scrolling which was fixed after bug 194886.

To make sure the prewarm message is handled in the Web process before the process is suspended,
the process should have a process assertion. This can be fixed by sending the prewarm message
inside WebProcessPool::initializeNewWebProcess, since all message sent inside this method are
guaranteed to be handled before the WebContent process is suspended.

This patch is based on Chris Dumez' idea and obervation of the issue.

Update double-conversion to the latest version
https://bugs.webkit.org/show_bug.cgi?id=194994

Import the latest version of the double-conversion library based on
https://github.com/google/double-conversion/commit/990c44707c70832dc1ce1578048c2198bafd3307

In additon to importing the code, the following changes were applied (or re-applied) to maintain
parity with what we had previously:

Add #include "config.h" to each cpp file.
Put everything inside the WTF namespace.
Changed all in library includes to be of the form #include <wtf/dtoa/FILE.h>.
Renamed double_conversion::Vector<> to double_conversion::BufferReference<>.
Replaced duplicated functions with ASCIICType.h variants
Made CachedPower table a constexpr.
Exported (via WTF_EXPORT_PRIVATE) several functions in double-conversion.h.
Made substantial changes to StringToDoubleConverter to avoid unnecessary overhead of parameterization, as we only ever want one configuration. Instead of constructing a configured class and calling StringToDouble on it, StringToDouble is now a static function. This allows a bunch of now dead code (hex support, octal support, etc.) to be eliminated. As StringToDoubleConverter now supports single precision floats, some additional templating of StringToIeee was added to avoid extra unnecessary branching.
Added RemoveCharacters function to double_conversion::StringBuilder.

[JSC] Drop direct references to Intl constructors by rewriting Intl JS builtins in C++
https://bugs.webkit.org/show_bug.cgi?id=194976

Reviewed by Michael Saboff.

This patch paves the way to making IntlObject allocation lazy by removing direct references
to Intl constructors (Intl.Collator etc.) from builtin JS. To achieve that,

We implement String.prototype.toLocaleCompare and Number.prototype.toLocaleString in C++ instead of JS builtins. Since these functions end up calling ICU C++ runtime, writing them in JS does not offer performance improvement.

We remove @DateTimeFormat constructor reference, and instead, exposing @dateTimeFormat function, which returns formatted string directly. We still have JS builtins for DateTimeFormat things because the initialization of its "options" JSObject involves many get_by_id / put_by_id things, which are efficient in JS. But we avoid exposing @DateTimeFormat directly, so that Intl constructors can be lazily allocated.

IndexedDB: IDBDatabase and IDBTransaction are leaked in layout tests
https://bugs.webkit.org/show_bug.cgi?id=194709

Reviewed by Geoffrey Garen.

Source/WebCore:

When connection to IDB server is closed, IDBTransaction would abort without notifying IDBDatabase, so
IDBDatabase didn't clear its reference to IDBTransaction which created a reference cycle.

Also IDBTransaction didn't clear its reference to IDBRequest in this case and it led to another reference cycle
between IDBOpenDBRequest and IDBTransaction.

Incorrect use of String::foldCase for font family names
https://bugs.webkit.org/show_bug.cgi?id=194895

Reviewed by Myles C. Maxfield.

platform/graphics/FontCascadeDescription.cpp:

(WebCore::FontCascadeDescription::familiesEqualForTextAutoSizing): Use
familyNamesAreEqual instead of calling convertToASCIILowercase directly.
(WebCore::FontCascadeDescription::familyNamesAreEqual): Use AtomicString's
operator== when we want case sensitive family name comparisons. This is a special
case to accomodate CoreText, which uses "."-prefix names for internal fonts that
are treated case sensitively. (Ideally webpages would not use these fonts at all.)
(WebCore::FontCascadeDescription::familyNameHash): Use AtomicString's existingHash
when we want case sensitive family name hashing.
(WebCore::FontCascadeDescription::foldedFamilyName): Take a String instead of an
AtomicString so we can use this at an additional call site. Converting from an
AtomicString to a String if free and automatic at the existing call sites. Use
convertToASCIILowercase instead of foldCase for three reasons: 1) Other functions
here are folding only ASCII case by using ASCIICaseInsensitiveHash, and this one
must be consistent. 2) this is considerably faster, and 3) font family names don't
need arbitrary Unicode case folding, it's only A-Z that should be folded.

platform/graphics/FontCascadeDescription.h: Take a String instead of AtomicString

in the foldedFamilyName function.

platform/graphics/cocoa/FontCacheCoreText.cpp:

(WebCore::FontDatabase::collectionForFamily): Instead of calling foldCase, use
FontCascadeDescription::foldedFamilyName to correctly fold font family names.

UniqueIDBDatabase should ignore requests from connections that are already closed.

Tests are hard to create without some tricks on UniqueIDBDatabase so this fix is verified manually.
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.

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.

Web Inspector: make debounce Proxy into its own class
https://bugs.webkit.org/show_bug.cgi?id=194721

Reviewed by Joseph Pecoraro.

Source/WebInspectorUI:

The debounce/throttle functions leveraged a Proxy to intercept the function call and
replace it with a "delayed" version. The issue with this is that it set the identifier for
the timer on the function itself, which is shared across all instances of a given class.
When different instances call the same delayed function, they'd clobber eachother's attempts
to delay work.

[JSC] Lazily create sentinel Map and Set buckets

Reviewed by Saam Barati.

If VM::canUseJIT() returns false, we can lazily initialize sentinel Map and Set buckets.
This patch adds getters to VM which lazily allocate these buckets. We eagerly initialize
them if VM::canUseJIT() returns true since they can be touched from DFG and FTL.

arguments, since it only worked for things that the String constructor can handle.

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.

<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.

Exit early when m_jobQueue is empty. Also add a debug assert that this should never happen

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.

[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.

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.

Some refinements for Node and Document
https://bugs.webkit.org/show_bug.cgi?id=194764

Reviewed by Ryosuke Niwa.

Source/WebCore:

accessibility/AccessibilityObject.cpp:

(WebCore::AccessibilityObject::press): Use shadowHost instead of
deprecatedShadowAncestorNode.
(WebCore::AccessibilityObject::axObjectCache const): Tweak coding style.
(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.

page/EventHandler.cpp:

(WebCore::EventHandler::handleAccessKey): Update name of elementForAccessKey.

page/FocusController.cpp:

(WebCore::clearSelectionIfNeeded): Use shadowHost instead of deprecatedShadowAncestorNode.

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>

<rdar://problem/48249014>

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.

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().

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.

SelectionController should track an unordered Set of represented objects

The SelectionController interface is largely the same. Class and delegate

SelectionController tracks selected items in selection order. For the

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.

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.

[LFC][Floats] Add support for placing formatting roots in-between floats.
https://bugs.webkit.org/show_bug.cgi?id=194902

Reviewed by Antti Koivisto.

Source/WebCore:

This patch add support for placing a formatting root box in-between existing floats.
The initial vertical position of a formatting root is its static position which can make the box
placed above exsiting floats (whereas we can never place a regular float above existing floats.)

Update MIME type parser
https://bugs.webkit.org/show_bug.cgi?id=180526

Patch by Rob Buis <rbuis@igalia.com> on 2019-02-21
Reviewed by Darin Adler.

LayoutTests/imported/w3c:

Update improved test expectations.

web-platform-tests/xhr/overridemimetype-blob-expected.txt:

Source/WebCore:

Further testing showed the MIME parser needs these fixes:

stripWhitespace is wrong for removing HTTP whitespace, use stripLeadingAndTrailingHTTPSpaces instead.
HTTP Token code points checking for Rfc2045 and Mimesniff were mixed up, use the dedicated isValidHTTPToken for Mimesniff mode.
Quoted Strings were not unescaped/escaped, this seems ok for serializing but is wrong when gettings individual parameter values. Implement [1] and [2] Step 2.4 to properly unescape and escape.

This change also tries to avoid hard to read uses of find.

Test: ParsedContentType.Serialize
