Reviewed by JF Bastien.

Source/JavaScriptCore:

All JSC poisons are now defined in JSCPoison.h.

Change all clients to use the new poison values via the POISON() macro.

The LLInt code has been updated to handle CodeBlock poison. Some of this code uses the t5 temp register, which is not available on the Windows port. Fortunately, we don't currently do poisoning on the Windows port yet. So, it will just work for now.

When poisoning is enabled for the Windows port, this LLInt code will need a
Windows specific implementation to workaround its lack of a t5 register.

Removed ConstExprPoisoned and its artifacts.

Changed all clients of ConstExprPoisoned to use Poisoned instead.

Worked around the GCC and Clang compiler bug that confuses an intptr_t& template arg with intptr_t. See use of std::enable_if_t<Other::isPoisoned> in Poisoned.h.

Removed ENABLE(MIXED_POISON) since we now have a workaround (3) that makes it possible to use the mixed poison code.

Also fixed broken implementation of comparison operators in Poisoned.

Data URL fonts split in the middle of an alphabet cause random letters to disappear
https://bugs.webkit.org/show_bug.cgi?id=175845
<rdar://problem/33996578>

Reviewed by Brent Fulgham.

Source/WebCore:

It is fairly common practice for a font foundry to split a font up into two files such that a semi-random
half of the alphabet is present in one of the files, and the other half is present in the other file. This
practice involves representing the files as data URLs, so as to minimize the time it takes to load them.

Because resource loading is asynchronous (even for data URLs), it is possible today to get a paint after
the first file is loaded but before the second file is loaded. Indeed, because of the way font fallback
works, we will never start loading the second file until a layout has occurred with the first font.

Because a site usually only uses this pattern for a handful of fonts, and I've never seen this pattern
being used for CJK fonts, it isn't very expensive to opportunistically decode these data URLs eagerly.
Using this method doesn't actually guarantee that the two fonts will load in between successive paints,
but it at least makes this much more likely. This patch implements this strategy, along with a size
threshold to make sure that we won't decode any super large data URLs when it isn't necessary.

History state should be updated during client redirects with asynchronous policy decisions
https://bugs.webkit.org/show_bug.cgi?id=181358
<rdar://problem/35547689>

Reviewed by Andy Estes.

Source/WebCore:

When decidePolicyForNavigationAction is responded to asynchronously during a client redirect,
HistoryController::updateForRedirectWithLockedBackForwardList does not update the history because
the document loader has not been marked as a client redirect because the FrameLoader only looks
at its provisional document loader to mark it as a client redirect. When decidePolicyForNavigationAction
is responded to asynchronously, though, the FrameLoader's provisional document loader has moved to
its policy document loader. To get both asynchronous and synchronous cases, let's just mark the document
loader as a client redirect whether it's the provisional or policy document loader.

Covered by a new API test.

Move ExitProfile to UnlinkedCodeBlock so it can be shared amongst CodeBlocks backed by the same UnlinkedCodeBlock
https://bugs.webkit.org/show_bug.cgi?id=181545

Reviewed by Michael Saboff.

This patch follows the theme of putting optimization profiling information on
UnlinkedCodeBlock. This allows the unlinked code cache to remember OSR exit data.
This often leads to the first compile of a CodeBlock, backed by an UnlinkedCodeBlock
pulled from the code cache, making better compilation decisions, usually
resulting in fewer exits, and fewer recompilations.

This is a 1% Speedometer progression in my testing.

[Cocoa] CTFontCopyDefaultCascadeListForLanguages() can return nullptr

<rdar://problem/36334637>

Reviewed by Jon Lee.

Speculative fix. We are getting crash reports saying that this call can return nullptr, and we
don't check for it.

No new tests because I couldn't find the specific input that causes it to return nullptr. (I
tried running this code with every 0, 1, and 2 length locale string, every weight value, and
every italic value, and couldn't get it to crash. I also inspected the code to figure out what
values would cause it to return nullptr, and I couldn't find anything other than if the system
has a totally busted font setup.)

[WebGL] Simulated vertexAttrib0 can sometimes cause OUT_OF_MEMORY errors

Source/WebCore:

Very large element indices in the ELEMENT_ARRAY_BUFFER meant that
our simulated vertexAttrib0 buffer might be too large. We need
to check for out-of-memory, but we can also detect some of the issues
earlier in our validation code. Additionally, make sure that we don't
accidentally cast an unsigned to a signed.

CheckStructure can be incorrectly subsumed by CheckStructureOrEmpty

stress/check-structure-ir-ensures-empty-does-not-flow-through.js: Added.

(runNearStackLimit.t):
(runNearStackLimit):
(test.f):
(test):

Source/JavaScriptCore:

The semantics of CheckStructure are such that it does not allow the empty value to flow through it.
However, we may eliminate a CheckStructure if it's preceded by a CheckStructureOrEmpty. This doesn't
have semantic consequences when validation is turned off. However, with validation on, this trips up
our OSR exit machinery that says when an exit is allowed to happen.

Consider the following IR:

a: GetClosureVar Or any other node that produces BytecodeTop
...
c: CheckStructure(Cell:@a, {s2})
d: PutByOffset(KnownCell:@a, KnownCell:@a, @value)

In the TypeCheckHoistingPhase, we may insert CheckStructureOrEmptys like this:
a: GetClosureVar
e: CheckStructureOrEmpty(@a, {s1})
...
f: CheckStructureOrEmpty(@a, {s2})
c: CheckStructure(Cell:@a, {s2})
d: PutByOffset(KnownCell:@a, KnownCell:@a, @value)

This will cause constant folding to change the IR to:
a: GetClosureVar
e: CheckStructureOrEmpty(@a, {s1})
...
f: CheckStructureOrEmpty(@a, {s2})
d: PutByOffset(KnownCell:@a, KnownCell:@a, @value)

Our mayExit analysis determines that the PutByOffset should not exit. Note
that AI will determine the only value the PutByOffset can see in @a is
the empty value. Because KnownCell filters SpecCell and not SpecCellCheck,
when lowering the PutByOffset, we reach a contradiction in AI and emit
an OSR exit. However, because mayExit said we couldn't exit, we assert.

Note that if we did not run the TypeCheckHoistingPhase on this IR, AI
would have determined we would OSR exit at the second CheckStructure.

This patch makes it so constant folding produces the following IR:
a: GetClosureVar
e: CheckStructureOrEmpty(@a, {s1})
g: AssertNotEmpty(@a)
...
f: CheckStructureOrEmpty(@a, {s2})
h: AssertNotEmpty(@a)
d: PutByOffset(KnownCell:@a, KnownCell:@a, @value)

This modification will cause AI to know we will OSR exit before even reaching
the PutByOffset. Note that in the original IR, the GetClosureVar won't
actually produce the TDZ value. If it did, bytecode would have caused us
to emit a CheckNotEmpty before the CheckStructure/PutByOffset combo. That's
why this bug is about IR bookkeeping and not an actual error in IR analysis.
This patch introduces AssertNotEmpty instead of using CheckNotEmpty to be
more congruous with CheckStructure's semantics of crashing on the empty value
as input (on 64 bit platforms).

[JSC] Create parallel SlotVisitors apriori
https://bugs.webkit.org/show_bug.cgi?id=180907

Reviewed by Saam Barati.

The number of SlotVisitors are capped with the number of HeapHelperPool's threads + 2.
If we create these SlotVisitors apropri, we do not need to create SlotVisitors dynamically.
Then we do not need to grab locks while iterating all the SlotVisitors.

In addition, we do not need to consider the case that the number of SlotVisitors increases
after setting up VisitCounters in MarkingConstraintSolver since the number of SlotVisitors
does not increase any more.

Source/JavaScriptCore:

Before this patch, the very first block in the switch for polymorphic call
inlining will have exitOK at the top. The others are not guaranteed to.
That was just a bug. They're all exitOK at the top. This will lead to crashes
in FixupPhase because we won't have a node in a block that has ExitOK, so
when we fixup various type checks, we assert out.

[WebAuthN] Import a CBOR coder from Chromium
https://bugs.webkit.org/show_bug.cgi?id=181522
<rdar://problem/36055729>

Reviewed by Brent Fulgham.

Source/WebCore:

This patch imports a CBOR coder including encoder and decoder from Chromium. CBOR encoder
is needed for WebAuthN to encode attestation object into binaries. When supporting extensions
in the future, CBOR encoder/decoder will be needed as well. Implementating and maintaining
a fully-fledged CBOR coder doesn't seem to align with WebKit's best interests. Therefore,
importing a most suitable third party implementation will be wise.

In this patch, it fully integrate the whole coder into our codebase. Those changes includes:

Substitute data structures that enjoy a better WTF version.
Replacing marcos.
Implementating workarounds for some functionalities that we lack fundamental types' support.
Changing the coding style to match ours.

This patch doesn't intend to improve the logic of the original codebase. Hence some of the
coding logic might not match what WebKit ususally has.

Here is a full list of Chromium changes that constructed this CBOR coder in chronological order:

[Cocoa] Star character disappears when bolded
https://bugs.webkit.org/show_bug.cgi?id=181568
<rdar://problem/18755569>

Reviewed by Simon Fraser.

Source/WebCore:

We had some code in ComplexTextController to ask the FontCache for a font, given the name
of a particular font CoreText used inside a CTRun. This is wrong for two reasons: fonts
are not identifiable by PostScript name (in the general case), and because the lookup
procedure requires a FontDescription, the result may yield a font that is not the one
looked up. The goal of this code was simply to preserve the rendering mode of the font,
but we removed support for these rendering modes years ago. So the solution is to skip
that lookup and use the CoreText font directly.

REGRESSION(r219530): ResourceLoadStatisticsPersistentStorage should be read-only in ephemeral sessions
https://bugs.webkit.org/show_bug.cgi?id=181136
<rdar://problem/36116604>

Reviewed by Chris Dumez.

Source/WebKit:

Some uses of WebKit involve running a UIProcess as an ephemeral session for the life of the process. In this
case, we do not initialize the data path for the set of load statistics triggering an assertion.

We actually intended ephemeral sessions to consume the existing resource load data (presumably captured during
non-ephemeral browsing). This would be a read-only mode, where it would not add new entries to the load
statistics, but would take advantage of existing observations. Currently that does not happen (for this type
of WebKit embed), which forces each run as an ephemeral session to build up in-memory browsing data until it has
enough observations to begin modifying loads.

We need to set the ResourceLoadStatisticsPersistentStorage object to a "read only" mode in this case, so
that it read (but does not write) from this database.

Tested by ephemeral website data TestWebKitAPI tests.

Don't load inline data when requesting info for an attachment element backed by a file path
https://bugs.webkit.org/show_bug.cgi?id=181550

Source/WebCore:

Reviewed by Tim Horton.

When requesting data for an attachment element that is backed by a file path, we currently trigger a load in the
web process to fetch contents of the attachment data as inline data in the AttachmentInfo. This is unnecessary,
since the file path of the attachment element must have come from the UI process anyways, so it is sufficient to
simply send the file path to the UI process and have the UI process read the contents of the path as a memory-
mapped NSData.

This patch lets HTMLAttachmentElement skip over resource loading codepaths when creating an AttachmentInfo for
the client, and also teaches _WKAttachment to read a AttachmentInfo's filepath as memory-mapped data if a file
path is present, and no inline data was specified.

Covered by existing API tests.

Rename MarkedAllocator to BlockDirectory and AllocatorAttributes to CellAttributes
https://bugs.webkit.org/show_bug.cgi?id=181543

Rubber stamped by Michael Saboff.
Source/JavaScriptCore:

In a world that has thread-local caches, the thing we now call the "MarkedAllocator" doesn't
really have anything to do with allocation anymore. The allocation will be done by something
in the TLC. When you move the allocation logic out of MarkedAllocator, it becomes just a
place to find blocks (a "block directory").

Once we do that renaming, the term "allocator attributes" becomes weird. Those are really the
attributes of the HeapCellType. So let's call them CellAttributes.

REGRESSION(r225003): Loading hangs in environments where dispatch_async does not work
https://bugs.webkit.org/show_bug.cgi?id=181553
Source/WebCore:

<rdar://problem/35733938>

Reviewed by Eric Carlson.

There is an environment where dispatch_async does not work, but performSelectorOnMainThread works.
r225003 broke loading in this environment. This fixes it and updates the test that r225003 fixed.
It failed sometimes because loading was happening in a different order than html parsing, so I made
the test not depend on html parsing timing by updating media/video-src-remove.html.

When inserting Unreachable in byte code parser we need to flush all the right things

Source/JavaScriptCore:

I added code in r226655 that had its own mechanism for preserving liveness when
inserting Unreachable nodes after ForceOSRExit. There are two ways to preserve
liveness: PhantomLocal and Flush. Certain values *must* be flushed to the stack.
I got some of these values wrong, which was leading to a crash when recovering the
callee value from an inlined frame. Instead of making the same mistake and repeating
similar code again, this patch refactors this logic to be shared with the other
liveness preservation code in the DFG bytecode parser. This is what I should have
done in my initial patch.

Only listen to webkitplaybacktargetavailabilitychanged when media controls are visible to the user
https://bugs.webkit.org/show_bug.cgi?id=181547
<rdar://problem/35947650>

Reviewed by Eric Carlson.

Source/WebCore:

Because listening to "webkitplaybacktargetavailabilitychanged" events incurs some higher power usage on iOS,
we only listen to such events when controls are visible to the user. In other words, the MediaControls need to
have both "visible" set to "true" and "faded" set to "false". To support this, we add a delegate method on
MediaControls such that it can tell the MediaController that the "visible" property changed. With this message,
MediaController can inform its MediaControllerSupport objects that user visibility of the controls changed, which
lets AirplaySupport disable itself when controls are no longer visible.

Merge sync and async code paths for getting context menus
https://bugs.webkit.org/show_bug.cgi?id=181423

Reviewed by Joseph Pecoraro.

What a mess. We had a code path for asynchronous context menu generation and a different one for synchronous context menu generation.
This makes it so there is just one. At the API level we see if there is an asynchronous delegate to call, then synchronous.
There is a subtle theoretical change in behaviour because m_page.contextMenuClient().showContextMenu is now called for the asynchronous
case and it wasn't before, but the one C API client that uses this has nullptr as it's WKPageShowContextMenuCallback, so we won't break anything!

[Attachment Support] Support moving attachment elements in editable areas using drag and drop
https://bugs.webkit.org/show_bug.cgi?id=181337
<rdar://problem/36324813>

Reviewed by Tim Horton.

Source/WebCore:

Makes slight adjustments to attachment-specific drag and drop logic to ensure that moving attachments via drag
and drop behaves correctly. See per-change comments for more detail.

Tests: WKAttachmentTests.DragInPlaceVideoAttachmentElement

WKAttachmentTests.MoveAttachmentElementAsIconByDragging
WKAttachmentTests.MoveInPlaceAttachmentElementByDragging

editing/cocoa/EditorCocoa.mm:

(WebCore::Editor::getPasteboardTypesAndDataForAttachment):

Stop vending the private web archive pasteboard type for attachments, for now. This works around issues where an
attachment element that is dragged and dropped within the same page may lose its blob backing data if we try to
remove and insert it as a fragment from the archive. Providing a web archive would allow us to avoid destroying
and recreating an attachment element when dragging within the same page, but this is a nice-to-have optimization
we can re-enable after investigation in a subsequent patch.

html/HTMLAttachmentElement.cpp:

(WebCore::HTMLAttachmentElement::populateShadowRootIfNecessary):

Add draggable=false to the image element of an in-place attachment element.

page/DragController.cpp:

(WebCore::enclosingAttachmentElement):
(WebCore::DragController::draggableElement const):

Tweak single-selected-attachment handling to account for in-place attachments. Since the hit-tested node is
inside the shadow subtree of the attachment element, the condition needs to check for the startElement as well
as the startElement's shadow host.

(WebCore::DragController::startDrag):

Make two tweaks here. First, don't require a RenderAttachment to drag an attachment element (this is required
for dragging in-place attachments). This was added in r217083 to address <rdar://problem/32282831>, but is no
longer correct, since attachments may now be displayed in-place.

Secondly, only restore the previous selection if the attachment is in a richly contenteditable area. This was
added to prevent the selection highlight from appearing in when dragging non-editable attachment elements in the
Mail viewer. However, to allow drag moves to occur, we need the selection to persist after drag start.

Tools:

Add 3 new API tests for attachment element dragging.

Reserve a fast TLS key for GC TLC
https://bugs.webkit.org/show_bug.cgi?id=181539

Reviewed by Alexey Proskuryakov.

Who knew that thread-local caches would be a mitigation for timing attacks. Here's how it
works: if we have TLCs then we can "context switch" them when we "context switch" origins.
This allows us to put some minimal distance between objects from different origins, which
gives us the ability to allow small overflows when doing certain bounds checks without
creating a useful Spectre information leak.

So I think that means we have to implement thread-local caches (also known as thread-local
allocation buffers, but I prefer the TLC terminology).

CodeBlocks should be in IsoSubspaces
https://bugs.webkit.org/show_bug.cgi?id=180884

Reviewed by Saam Barati.
Source/JavaScriptCore:

This moves CodeBlocks into IsoSubspaces. Doing so means that we no longer need to have the
special CodeBlockSet HashSets of new and old CodeBlocks. We also no longer use
WeakReferenceHarvester or UnconditionalFinalizer. Instead:

Code block sweeping is now just eager sweeping. This means that it automatically takes advantage of our unswept set, which roughly corresponds to what CodeBlockSet used to use its eden set for.

Those idea of Executable "weakly visiting" the CodeBlock is replaced by Executable marking a ExecutableToCodeBlockEdge object. That object being marked corresponds to what we used to call CodeBlock "having been weakly visited". This means that CodeBlockSet no longer has to clear the set of weakly visited code blocks. This also means that determining CodeBlock liveness, propagating CodeBlock transitions, and jettisoning CodeBlocks during GC are now the edge's job. The edge is also in an IsoSubspace and it has IsoCellSets to tell us which edges have output constraints (what we used to call CodeBlock's weak reference harvester) and which have unconditional finalizers.

CodeBlock now uses an IsoCellSet to tell if it has an unconditional finalizer.

CodeBlockSet still exists! It has one unified HashSet of CodeBlocks that we use to handle requests from the sampler, debugger, and other facilities. They may want to ask if some pointer corresponds to a CodeBlock during stages of execution during which the GC is unable to answer isLive() queries. The trickiest is the sampling profiler thread. There is no way that the GC's isLive could tell us of a CodeBlock that had already been allocated has now been full constructed.

Rolling this back in because it was rolled out by mistake. There was a flaky crash that was
happening before and after this change, but we misread the revision numbers at first and
thought that this was the cause.

Adds support for dragging "files" (i.e. creating item providers with preferred attachment presentation styles)
from attachment elements on iOS for Mail. See below for more detail.

page/DragController.h:
page/mac/DragControllerMac.mm:

(WebCore::DragController::platformContentTypeForBlobType const):

Add a private method to convert the type of a promised blob to a platform type. For Cocoa platforms, this
converts the blob type (either a UTI or a MIME type) to a UTI for the platform to consume.

platform/ios/WebItemProviderPasteboard.h:
platform/ios/WebItemProviderPasteboard.mm:

Refactor WebItemProviderRegistrationInfo. WebItemProviderRegistrationInfo currently encapsulates a single item
provider registration call, and contains either a type identifier and data buffer, or an NSItemProviderWriting-
conformant object. To register an item provider using a WebItemProviderRegistrationInfo, the item provider
pasteboard currently checks to see whether the info contains an object or a type and data.

This patch removes WebItemProviderRegistrationInfo and replaces it with WebItemProviderDataRegistrar. Objects
that implement this protocol know how to take an NSItemProvider and register data to it. So far, there are
three implementations below.

(-[WebItemProviderDataRegistrar initWithData:type:]):

(-[WebItemProviderWritableObjectRegistrar representingObjectForClient]):
(-[WebItemProviderWritableObjectRegistrar registerItemProvider:]):
(-[WebItemProviderWritableObjectRegistrar description]):

The writable object registrar writes an NSItemProviderWriting-conformant object to an item provider. This

Implement support for registering and beginning a drag with promised blob info. See below for more detail.

UIProcess/ios/WKContentViewInteraction.mm:

(-[WKDragSessionContext addTemporaryDirectory:]):
(-[WKDragSessionContext cleanUpTemporaryDirectories]):

Introduce WKDragSessionContext, which represents the localContext of a UIDragSession initiated in WebKit. The
blob promise dragging codepath uses this to register temporary directories when saving blob data to a location
on disk; when all data transfers are finished, or if the drag interaction is being reset, we then use
-cleanUpTemporaryDirectories to remove each temporary directory.

(existingLocalDragSessionContext):
(ensureLocalDragSessionContext):

Helper methods to set the UIDragSession's localContext to a WKDragSessionContext and query for any existing
context.

(-[WKContentView cleanupInteraction]):

Before the content view's UIDragInteraction goes away, clean up any temporary directories added to the
UIDragSession.

(-[WKContentView _prepareToDragPromisedBlob:]):

When dragging with a promised blob, register a new item provider on the pasteboard representing the blob data,
along with any additional metadata associated with the blob. For the promise callback, call out to the network
process to write the blob data to a temporary path; when done, call the NSItemProvider's completion handler with
the temporary blob data location.

(-[WKContentView _itemsForBeginningOrAddingToSessionWithRegistrationList:stagedDragSource:]):
(-[WKContentView dragInteraction:sessionDidTransferItems:]):

Use this delegate hook as an opportunity to remove any temporary directories created when promised blob data is
requested upon drop. Since we know the drag session that has finished transferring data, we simply ask its local
context (a WKDragSessionContext) to remove any temporary filepaths it has created.

Tools:

Add support in the drag and drop simulator for testing blob-backed attachment element dragging, and also add new
attachment API tests.

TestWebKitAPI/Tests/WebKitCocoa/WKAttachmentTests.mm:

(-[NSItemProvider expectType:withData:]):
(TestWebKitAPI::TEST):

Add two new WKAttachmentTests to exercise dragging data- and file-backed blobs via attachment elements. These
tests first insert attachments via drop or WKWebView SPI, and then drag these attachments out and use the
-expectType:withData: helper to inspect the item providers created from the drag source.

TestWebKitAPI/Tests/ios/DataInteractionTests.mm:

(TestWebKitAPI::TEST):

(-[DataInteractionSimulator _resetSimulatedState]):
(-[DataInteractionSimulator simulateAllTouchesCanceled:]):
(-[DataInteractionSimulator _concludeDataInteractionAndPerformOperationIfNecessary]):
(-[DataInteractionSimulator _advanceProgress]):
(-[DataInteractionSimulator endDataTransfer]):

Make some tweaks to the iOS drag and drop simulator. In particular, this patch (1) adds a new hook to tell
WebKit that data transfers have been completed, (2) fixes incorrect drop proposal handling when returning
UIDropOperationForbidden by replacing _shouldPerformOperation with a UIDropProposal, and (3) teach the
MockDragSession to hold on to a localContext.

make NewRegexp PhantomNewRegexp if it is not used except for setting/getting its lastIndex property.

To improve RegExp.prototype.@@match's performance more, we make this builtin function small by moving
slow path part to @matchSlow() private function.

It improves SixSpeed regex-u.{es5,es6} largely since they stress String.prototype.match, which calls
this regExpMatchFast function.

Our for-in caching would cache structure chains that had prototypes with

adds new indexed properties. We would continue to enumerate the old cached

Source/JavaScriptCore:

I wrote a script that finds interesting things to poison or
generally harden. These stood out because they derive from
JSObject and only contain a few pointer or pointer-like fields,
and could therefore just be poisoned. This also requires some
template "improvements" to our poisoning machinery. Worth noting
is that I'm making PoisonedUniquePtr move-assignable and
move-constructible from unique_ptr, which makes it a better
drop-in replacement because we don't need to use
makePoisonedUniquePtr. This means function-locals can be
unique_ptr and get the nice RAII pattern, and once the function is
done you can just move to the class' PoisonedUniquePtr without
worrying.

Reviewed by Simon Fraser.

UIProcess/API/Cocoa/WKWebView.mm:

(-[WKWebView _processDidExit]):
(-[WKWebView _didCommitLayerTree:]):
When swiping to a page that set history.scrollRestoration = "manual",
we will never restore the scroll position. We will still restore
"state", but won't have a location. Currently, the code assumes that
it should wait to remove the swipe snapshot until the scroll position
is restored. Instead, wait until the "state" is restored, whether
or not that includes a scroll position/center point restoration.

Do this by making _firstTransactionIDAfterPageRestore an optional,
and reset it after it fires, so that we only run the restoration code
in _didCommitLayerTree for the first commit after state restoration,
not all subsequent commits. Then, tell ViewGestureController that
the scroll position has been restored even if the page opted out.

The reason that this is specific to pushState is that normal,
non-same-document loads bail from waiting for the scroll position
restoration in VGC::didReachMainFrameLoadTerminalState() (see the long
comment there for an explanation).

Reviewed by Alex Christensen.

Covered by rebased tests.

Start to translate cache policy used for navigation as FetchOptions::Cache.
This allows ensuring service workers receive the right cache mode when intercepting navigation loads.
To not change current navigation behavior, ReturnCacheDataElseLoad and ReturnCacheDataDontLoad still trigger default fetch cache mode.

For Reload and ReloadExpiredOnly frame load types, using no-cache mode is more efficient than reload mode,
as a conditional request will be sent if possible. This applies to location.reload which is consistent with other browsers.
Keep reload mode for ReloadFromOrigin.

webkitpy: Refactor simulator code (Part 2)
https://bugs.webkit.org/show_bug.cgi?id=180555
<rdar://problem/36131381>

Reviewed by Aakash Jain.

The patch leverages the SimulatedDeviceManager when running layout tests.
This patch is primarily code removal, since much of the IOSSimulatorPort
was dedicated to managing simulators. The removed code is either now owned by the
SimulatedDeviceManager (and committed in Part 1) or supported a technique to
boot multiple simulators which was made obsolete in Xcode 9.

(Manager._custom_device_for_test.in): Device names now have spaces in them,
strip those spaces.

Scripts/webkitpy/layout_tests/run_webkit_tests.py:

Scripts/webkitpy/port/ios.py:

(IOSPort.init): The _current_device idiom is no longer required since the
SimulatedDeviceManager keeps track of any previously booted devices.
(IOSPort.target_host): Even when only a single device is used, it will be accessed
through the array of managed devices.
(IOSPort.using_multiple_devices): Deleted.

Scripts/webkitpy/port/ios_device.py:

(IOSDevicePort.using_multiple_devices): Deleted.

Scripts/webkitpy/port/ios_simulator.py:

(IOSSimulatorPort): Remove constants required to manage simulators, change device
class strings so they can be parsed by the DeviceType class.
(IOSSimulatorPort.init): Determine the number of processes to use by checking
the number of simulators currently booted, the number of child processes specified
and the maximum number of simulators supported by this system.
(IOSSimulatorPort._device_for_worker_number_map):Return the array of initialized
devices owned by the SimulatedDeviceManager.
(IOSSimulatorPort.ios_version): Remove support for the --runtime option.
(IOSSimulatorPort.default_child_processes): Use the SimulatedDeviceManager to check
the maximum number of supported simulators on this system.
(IOSSimulatorPort._create_devices): Construct a list of device requests with a
request for each child process and send this list to the SimulatedDeviceManager to
initialize the devices.
(IOSSimulatorPort.clean_up_test_run):

Add Service Worker CSP persistency
https://bugs.webkit.org/show_bug.cgi?id=181434

Patch by Youenn Fablet <youenn@apple.com> on 2018-01-10
Reviewed by Alex Christensen.

Covered by manual testing.
Future work on service worker test infrastructure should allow automating such tests.

Add support for service worker CSP data persistency.
Add a version parameter to increment each time the schema is changing.
This allows the same store to be used by multiple WebKits.

Merge r226018 - [GTK][WPE] Enable WebProcess memory monitor
https://bugs.webkit.org/show_bug.cgi?id=180861

Reviewed by Michael Catanzaro.

For some reason this is only enabled in mac. We want to enable it also in GTK and WPE ports. This runs every 30
seconds to release memory or even kill the process if necessary. Carlos López has realized that in some
applications using video tags, the memory grows a lot and it's never released. It seems it's not memory leaked,
but simply large memory allocations (I guess it's gst allocating video frames) that make the heap grow. The
memory pressure calls malloc_trim that releases all that memory keeping the web process footprint stable.

Merge r224458 - [GTK] Fix gtk-doc generation with gtk-doc master
https://bugs.webkit.org/show_bug.cgi?id=179252

Reviewed by Carlos Garcia Campos.

gtkdoc-scangobj has changed to no longer use a shell when executing its subcommands. In
particular, this means we can no longer rely on shell stuff in our run command that we use
to run the scanner. We currently use the RUN envvar to set LD_LIBRARY_PATH, and the end
result is gtkdoc-scangobj now attempts to execute our environment variable instead of the
scanner itself. We can just set LD_LIBRARY_PATH directly, instead of using RUN, in order to
make documentation generation work again.
