Crash when printing snapshotted plugins

Optional<ResourceLoadPriority> when needed instead. If the Optional
doesn't have a value, then it means it is unresolved. Having
ResourceLoadPriorityUnresolved in ResourceLoadPriority was confusing
because this value is only valid in CachedResourceRequest, it is not

[iOS] Selection Callout should not immediately disappear on pages with frequent layouts
https://bugs.webkit.org/show_bug.cgi?id=141210

Patch by Joseph Pecoraro <Joseph Pecoraro> on 2015-02-03
Reviewed by Enrica Casucci.

In iOS WebKit2 in order to keep caret refreshes in sync with WebCore layouts
the selection assistant is told to update whenever WebKit's layer tree
commits. Unfortunately, for pages with JavaScript animation that are
frequently doing a layout / layer tree update, this would trigger very
frequent selection updates that would keep the caret from blinking and
dismiss any selection callouts.

This change tracks the last selection drawing information so that we can
avoid informing the assistant of a selection updates unless it has changed
visually or needs to redraw (zoom).

Workaround a thread library bug where thread destructors may not get called.
<https://webkit.org/b/141209>

Reviewed by Michael Saboff.

There's a bug where thread destructors may not get called. As far as
we know, this only manifests on darwin ports. We will work around this
by checking at GC time if the platform thread is still valid. If not,
we'll purge it from the VM's registeredThreads list before proceeding
with thread scanning activity.

Note: it is important that we do this invalid thread detection during
suspension, because the validity (and liveness) of the other thread is
only guaranteed while it is suspended.

Convert WebInspectorProxy to use WKWebView API for the inspector view
https://bugs.webkit.org/show_bug.cgi?id=141037

Reviewed by Timothy Hatcher.

Use the newer API for PLATFORM(MAC). The main difference is that the
WKWebView's page group cannot be set directly; instead, the group identifier
is passed. Also add some preference setters needed for the inspector.

Refactor some code to not use page groups directly. In a future patch,
the PageGroup-based inspector level system will be simplified. It is
it is no longer necessary to keep a static map of PageGroup instances,
since they are only used to save inspector window preferences. (These used
to prevent all levels of inspector from pausing together when a second-level
inspector hit a breakpoint. This is not necessary with multi-process
web inspectors.)

Also, adjust window resizing behavior when the inspector is docked to
the right. Window width resizes should not affect the width of the inspector
frame. This matches the behavior of height changes when docked to the bottom.

To support 32-bit Mac builds where WKWebView is not defined, share the stub
platformFoo() implementations with PLATFORM(IOS). The stubs are now located
in the platform-independent WebInspectorProxy.cpp.

Smart quoting could move the caret backwards in some configurations
https://bugs.webkit.org/show_bug.cgi?id=141203
Source/WebCore:

<rdar://problem/17452543>

Reviewed by Enrica Casucci.

The bug was caused by markAndReplaceFor not running the code to preserve the selection after
text replacement only when smart quote is enabled. Furthermore, when smart link was disabled,
we never applied smart quote due to the following condition at line 2502:

if (!(shouldPerformReplacement

shouldCheckForCorrection

shouldMarkLink)

!doReplacement)

continue;

This condition prevented the code to apply smart quote from running when both continuous
spellchecking, smart link, and text replacement are disabled.

Fixed the bug by treating smart quotes and smart dashes like any other text replacement and set
shouldPerformReplacement to true whenever either one of those text checking options are present.

Smart link didn't have this issue due to the explicit check for shouldMarkLink.

Smart dashes didn't suffer this problem either because dashes replacement happens only once
the caret has moved past the dashes but his patch makes go through the same code path to preserve
the selection as well for consistency.

[MSE] Setting timestampOffset does not change the timestamps in the actual sample, leading to visual and audible errors.
https://bugs.webkit.org/show_bug.cgi?id=140929

Reviewed by Darin Adler.

Source/WebCore:

Test: media/media-source/media-source-timeoffset.html

Changing timestampOffset will correctly offset the presentation and decode times within SourceBuffer and
will correctly modify things like buffered ranges. But those changes need to be reflected in the underlying
MediaSample for decoders to decode and display the samples at the correct times.

Add a method to MediaSample which allows the caller to offset timestamps of the underlying PlatformMediaSample.

Modules/mediasource/SourceBuffer.cpp:

(WebCore::SourceBuffer::sourceBufferPrivateDidReceiveSample): Call offsetTimestampsBy() on the sample.

platform/MediaSample.h:
platform/graphics/avfoundation/objc/SourceBufferPrivateAVFObjC.mm:

arguments[-1] should have well-defined behavior
https://bugs.webkit.org/show_bug.cgi?id=141183

Reviewed by Mark Lam.

According to JSC's internal argument numbering, 0 is "this" and 1 is the first argument.
In the "arguments[i]" expression, "this" is not accessible and i = 0 refers to the first
argument. Previously we handled the bounds check in "arguments[i]" - where "arguments" is
statically known to be the current function's arguments object - as follows:

add 1, i
branchAboveOrEqual i, callFrame.ArgumentCount, slowPath

The problem with this is that if i = -1, this passes the test, and we end up accessing
what would be the "this" argument slot. That's wrong, since we should really be bottoming
out in arguments-1?, which is usually undefined but could be anything. It's even worse
if the function is inlined or if we're in a constructor - in that case the "this" slot
could be garbage.

It turns out that we had this bug in all of our engines.

This fixes the issue by changing the algorithm to:

load32 callFrame.ArgumentCount, tmp
sub 1, tmp
branchAboveOrEqual i, tmp, slowPath

In some engines, we would have used the modified "i" (the one that had 1 added to it) for
the subsequent argument load; since we don't do this anymore I also had to change some of
the offsets on the BaseIndex arguments load.

This also includes tests that are written in such a way as to get coverage on LLInt and
Baseline JIT (get-my-argument-by-val-wrap-around-no-warm-up), DFG and FTL
(get-my-argument-by-val-wrap-around), and DFG when we're being paranoid about the user
overwriting the "arguments" variable (get-my-argument-by-val-safe-wrap-around). This also
includes off-by-1 out-of-bounds tests for each of these cases, since in the process of
writing the patch I broke the arguments[arguments.length] case in the DFG and didn't see
any test failures.

JIT Compile simple cases of :nth-last-child()
https://bugs.webkit.org/show_bug.cgi?id=141053

Reviewed by Andreas Kling.

Source/WebCore:

This patch adds the code generator for :nth-last-child(), skipping
any :nth-last-child(An+B of selector list).

The code generator is boring here, nothing fancy.
There is no optimization opportunity here so it is basically the same
speed as the code generated by Clang when the simple selector is alone.

The only reason to JIT compile this is to avoid going to slow-path
for every selector that contain :nth-last-child().

cssjit/SelectorCompiler.cpp:

(WebCore::SelectorCompiler::addNthChildType):
The code creating the intermediate representation of :nth-child() is exactly
the same as what we need for :nth-last-child(). I extracted the code from addPseudoClassType()
and share it for both simple selectors.

(WebCore::SelectorCompiler::addPseudoClassType):
I fail :nth-last-child(An+B of selector list). Let's add it later.

(WebCore::SelectorCompiler::minimumRegisterRequirements):
Oops, there was a bug with nthChildOfFilters.

(WebCore::SelectorCompiler::SelectorCodeGenerator::generateElementMatching):
(WebCore::SelectorCompiler::setChildrenAffectedByBackwardPositionalRules):
(WebCore::SelectorCompiler::SelectorCodeGenerator::generateElementIsNthLastChild):

LayoutTests:

There was almost no test coverage for :nth-last-child(). I copied the main tests
from :nth-child() and updated the expected results.

This is not ideal because we should have style update tests targetting
backward invalidation... Still better than nothing :)

Defer painting operations until we have finished layout. This
has a couple of benefits:
(1) We do not attempt to modify render layers during layout.
(2) In WK1 we do not attempt to paint during layout.

Add a new virtual predicate to ScrollView indicating when we are in
layout so that calls to setContentsSize do not attempt
to adjust scrollbars.

Clean up attribute handling: part 2 - attributeNode
https://bugs.webkit.org/show_bug.cgi?id=141109

Patch by Benjamin Poulain <bpoulain@apple.com> on 2015-02-02
Reviewed by Andreas Kling.

Source/WebCore:

Our implementation was covering some old legacy behaviors of Firefox,
even copying bugs in some cases.

The spec (https://dom.spec.whatwg.org) now defines the behavior precisely,
let's move a bit closer to that.

Tests: fast/dom/Element/attribute-ascii-case-insensitive-3.html

fast/dom/Element/attribute-setAttributeNode-multiple-times.html
fast/dom/Element/attribute-setAttributeNodeNS-multiple-times.html
fast/dom/Element/mozilla-dom-base-tests/test_bug1075702.html

fast/dom/Element/mozilla-dom-base-tests/test_bug364092.xhtml
fast/dom/Element/setAttributeNode-overriding-lowercase-values.html

dom/Element.cpp:

(WebCore::findAttrNodeInList):
New getter for the name-without-namespace case.

(WebCore::Element::setAttributeNode):
This one is the tricky one: https://dom.spec.whatwg.org/#dom-element-setattributenode

When setAttributeNode() is used with an AttributeNode without namespace,
getting the old value behaves like getAttribute(), with ASCII lowercase name matching.
When used with a namespace, getting the old value behaves like getAttributeNS().

Setting the value is a whole different story, the name used always keeps
the original case.

Now that's a bit tricky for us because AttributeNodes are just legacy stuff we don't
used internally.

We have 4 cases to handle:
1) The name being set is lowercase, there was no conflicting name on the element.

That's easy, we just override any node that would exist, set the name otherwise.

2) The name is lowercase but there was an existing attribute for it.

-We create a new AttributeNode for the name to represent the old name.
-We check the names are the same with attribute.name().matches(attrNode->qualifiedName())

and override the value.

3) The name has uppercase characters, there is no conflicting name.

We would not find an element to remove, we just use setAttributeInternal() as usual
to add the attribute;

4) The name has uppercase characters, there is a lowercase conflicing name.

This is the weird behavior: we need to nuke the old attribute, then add the new attribute
with a different case.

First we remove the attribute with a lowercase name with removeAttributeInternal().
That becomes the old node.

There might still be an element of the same name as what we are trying to add. We don't want

[Cocoa] Make decoded image data purgeable ASAP.
<https://webkit.org/b/140298>
<rdar://problem/19623377>

Reviewed by Antti Koivisto.

Re-landing this patch since it turned out to not be the cause of
the memory regression we saw around that revision.

Mark decoded images as "transient" which makes CoreGraphics mark
the backing stores as purgeable shortly after they're used.

The decoded representation will remain in CoreGraphics's caches
indefinitely unless the kernel gets starved and needs the pages.

Most resources will now reach a state where the encoded data is
mmap'ed from disk cache (once the entire resource is downloaded)
and the decoded data is purgeable.

This also has the side effect of making the MemoryCache more
palatial since the decoded data cost can be deducted for images,
allowing us to cache more resources.

Note that the worst case for this new behavior would be something
like hovering below 100% memory utilization and constantly having
to drop and re-decode images. While churny, it still beats
crashing the process, plus there's tiling to remove many of the
reasons we'd need the decoded data.

BinarySwitch should be faster on average
https://bugs.webkit.org/show_bug.cgi?id=141046

Reviewed by Anders Carlsson.

This optimizes our binary switch using math. It's strictly better than what we had before
assuming we bottom out in some case (rather than fall through), assuming all cases get
hit with equal probability. The difference is particularly large for large switch
statements. For example, a switch statement with 1000 cases would previously require on
average 13.207 branches to get to some case, while now it just requires 10.464.

This is also a progression for the fall-through case, though we could shave off another
1/6 branch on average if we wanted to - though it would regress taking a case (not falling
through) by 1/6 branch. I believe it's better to bias the BinarySwitch for not falling
through.

This also adds some randomness to the algorithm to minimize the likelihood of us
generating a switch statement that is always particularly bad for some input. Note that
the randomness has no effect on average-case performance assuming all cases are equally
likely.

This ought to have no actual performance change because we don't rely on binary switches
that much. The main reason why this change is interesting is that I'm finding myself
increasingly relying on BinarySwitch, and I'd like to know that it's optimal.

Get rid of invalidSelectorVector, use Bison's error recovery instead
https://bugs.webkit.org/show_bug.cgi?id=141147

Reviewed by Darin Adler.

css/CSSGrammar.y.in:

Instead of reducing a null selector, we can use a real parsing error
to get out of invalid selector endings.

When that happens, Bison will pop the stack until it can reduce any
valid error recovery rules.

The problem is to make sure there is no floating values because
none of the reduce block between the error and the recovery would
be executed.

In this case, "nth_selector_ending" is a non-recursive production of
the NTHCHILDFUNCTIONS. In turn, NTHCHILDFUNCTIONS are productions
of the non-recursive "pseudo". "pseudo" is only used as a trivial
production of "specifier". "specifier" is only used by "specifier_list".

"specifier_list" has error recovery code -> no production could have
generated a floating values between "specifier_list" and "nth_selector_ending".

Polymorphic call inlining should be based on polymorphic call inline caching rather than logging
https://bugs.webkit.org/show_bug.cgi?id=140660

Reviewed by Geoffrey Garen.

When we first implemented polymorphic call inlining, we did the profiling based on a call
edge log. The idea was to store each call edge (a tuple of call site and callee) into a
global log that was processed lazily. Processing the log would give precise counts of call
edges, and could be used to drive well-informed inlining decisions - polymorphic or not.
This was a speed-up on throughput tests but a slow-down for latency tests. It was a net win
nonetheless.

Experience with this code shows three things. First, the call edge profiler is buggy and
complex. It would take work to fix the bugs. Second, the call edge profiler incurs lots of
overhead for latency code that we care deeply about. Third, it's not at all clear that
having call edge counts for every possible callee is any better than just having call edge
counts for the limited number of callees that an inline cache would catch.

So, this patch removes the call edge profiler and replaces it with a polymorphic call inline
cache. If we miss the basic call inline cache, we inflate the cache to be a jump to an
out-of-line stub that cases on the previously known callees. If that misses again, then we
rewrite that stub to include the new callee. We do this up to some number of callees. If we
hit the limit then we switch to using a plain virtual call.

Substantial speed-up on V8Spider; undoes the slow-down that the original call edge profiler
caused. Might be a SunSpider speed-up (below 1%), depending on hardware.

Rolling this back in after fixing https://bugs.webkit.org/show_bug.cgi?id=141107.

Converting Flushes and PhantomLocals to Phantoms requires an OSR availability analysis rather than just using the SetLocal's child
https://bugs.webkit.org/show_bug.cgi?id=141107

Reviewed by Michael Saboff.

See the bugzilla for a discussion of the problem. This addresses the problem by ensuring
that Flushes are always strength-reduced to PhantomLocals, and CPS rethreading does a mini
OSR availability analysis to determine the right MovHint value to use for the Phantom.

REGRESSION (r170576): Storage leaks in parsing of CSS image sizes
https://bugs.webkit.org/show_bug.cgi?id=141026

Reviewed by Anders Carlsson.

css/CSSGrammar.y.in: Fixed all the shift/reduce conflicts caused

by the ENABLE_PICTURE_SIZES code by removing all the redundant
maybe_space which caused them. Rearranged the productions for
ENABLE_PICTURE_SIZES to tighten up the code quite a bit. Changed
the code to build up the source size vector as a Vector instead of
a special class, and use the SourceSize struct from inside the
CSSParser class.'

css/CSSParser.cpp:

(WebCore::CSSParser::setupParser): Changed this to take a StringView.
In the future we can change all the parsing functions to take StringView,
since they don't work with the String in place.
(WebCore::CSSParser::parseSizesAttribute): Changed to return a vector
of SourceSize instead of a SourceSizeList. This is better because it's
a real CSS data structure that does not contain a CSSParserValue.
(WebCore::CSSParser::sourceSize): Added. Helper that creates a
SourceSize, mapping parser data structures into real CSS ones.

css/CSSParser.h: Updated for changes above.

css/MediaQuery.cpp:

(WebCore::MediaQuery::MediaQuery): Use std::make_unique and the copy
constructor directly instead of using a MediaQuery::copy function.

css/MediaQueryExp.cpp: Streamlined the class a little bit.
css/MediaQueryExp.h: Removed unneeded includes. Moved functions out

of the class body so the class is easier to read. Removed the unneeded
copy function.

css/SourceSizeList.cpp:

(WebCore::SourceSize::match): Changed to use WTF::move instead
of releasing and then re-creating the unique_ptr.
(WebCore::computeLength): Added a comment to explain this function
is using an incorrect strategy. Also added some type checking code
to handle cases where a null or non-primitive CSS value might be
returned. Probably dead code, but we don't want to risk a bad cast.
Worthe cleaning up when we fix the strategy.
(WebCore::SourceSizeList::getEffectiveSize): Updated since the
vector now contains actual SourceSize objects rather than pointers
to SourceSize objects on the heap.

css/SourceSizeList.h: Changed the CSSParserValue argument to be

an rvalue reference to make it clearer that we take ownership of it
when it's moved in. Added a move constructor and a destructor. Added
comments explaining that it's not correct design to use a
CSSParserValue here, outside the parser. Changed SourceSizeList's
append function to move a SourceSize in rather than a unique_ptr.
Made getEffectiveSize private. Moved the various inline functions to
the bottom of the file to make the class definitions easier to read.

css/SourceSizeList.cpp: Made almost everything about this private

to this source file instead of public in the header.
(WebCore::match): Made this a free function instead of a member function
and made it take the media query expression as an argument.
(WebCore::computeLength): Changed the argument type to CSSValue*,
rather than using CSSParserValue here outside the parser.
(WebCore::parseSizesAttribute): Streamlined and simplified this.
Now that the parser builds the list in the correct order, there was
no need to iterate backwards any more so we could use a modern for
loop.

css/SourceSizeList.h: Removed almost everything in this header.

html/HTMLImageElement.cpp:

(WebCore::HTMLImageElement::parseAttribute): Call the
parseSizesAttribute function as free function since it's no longer
a member of a SourceSizeList class.

html/parser/HTMLPreloadScanner.cpp:

(WebCore::TokenPreloadScanner::StartTagScanner::processAttributes):
Ditto.

Use simpler CachedResourceMap structure in MemoryCache with CACHE_PARTITIONING enabled
https://bugs.webkit.org/show_bug.cgi?id=141110

Reviewed by Antti Koivisto.

Use simpler CachedResourceMap structure in MemoryCache with CACHE_PARTITIONING
enabled. Previously, we would be using a HashMap of HashMap to store
CachedResources. The outer HashMap would use the URL as key and the inner
HashMap would use the partition name as key. This would make traversing the
structure overly complicated, especially considering that the code needs to
traverse a simple HashMap if CACHE_PARTITIONING is disabled.

This patch updates the CachedResourceMap structure to be a simple HashMap,
whose key is an std::pair<URL, String /* partitionName */>. Having a flat
structure simplifies the traversal code a lot and enables more code sharing
between CACHE_PARTITIONING and !CACHE_PARTITIONING. This shouldn't regress
performance because we always have both a URL and a partition name when we
need to look up a resource. We never need to retrieve all resources with
a particular URL.

This patch also switches to using a URL as key instead of a String as we
always have a URL has input.

platform/graphics/GraphicsContext.cpp:

(WebCore::GraphicsContext::drawText):
The only difference between the two implementation here was the iOS one returns the length of
the text that was drawn. As all platforms now support that, we can merge by keeping the iOS one.

(WebCore::GraphicsContext::drawBidiText):
This function had a few differences:

iOS returns the length of the text that was drawn.

Since this is not used anywhere, I dropped this ability.

iOS took additional inputs of initial bidi status and run length (and returned the the final bidi status as an out parameter)

Since this was also unused, I dropped it.

iOS used the fact that font.drawText() returns the length that was drawn, to avoid measuring the text twice.

I kept this, since all platforms now support this.

Get rid of the bitfield in RenderBlock by moving the essential bits to
RenderElement (plenty of space in the bitfield there.)

RenderBlock also had a cache of its line-height, but it doesn't appear

Previous attempt to special case dispatch_data_t in OSObjectPtr didn't work in all cases

Optimize MemoryCache::getSessionMap() a bit
https://bugs.webkit.org/show_bug.cgi?id=141069

Reviewed by Anders Carlsson.

Optimize MemoryCache::getSessionMap() a bit by doing 1 HashMap lookup
instead of previously 3. Also rename the method to
ensureSessionResourceMap() as we usually don't use "get" prefix for
getters and the implementation will also create the HashMap value if
the key is not found.

Also add a alternative sessionResourceMap() method which returns
the HashMap value if the key exists but doesn't try to create it if
missing. This is actually what we really want for some call sites.

Implement ES6 Symbol
https://bugs.webkit.org/show_bug.cgi?id=140435

Reviewed by Geoffrey Garen.

Source/JavaScriptCore:

This patch implements ES6 Symbol. In this patch, we don't support
Symbol.keyFor, Symbol.for, Object.getOwnPropertySymbols. They will be
supported in the subsequent patches.

Since ES6 Symbol is introduced as new primitive value, we implement
Symbol as a derived class from JSCell. And now JSValue accepts Symbol*
as a new primitive value.

Symbol has a *unique* flagged StringImpl* as an uid. Which pointer
value represents the Symbol's identity. So don't compare Symbol's
JSCell pointer value for comparison.
This enables re-producing Symbol primitive value from StringImpl* uid
by executingSymbol::create(vm, uid). This is needed to produce
Symbol primitive values from stored StringImpl* in Object.getOwnPropertySymbols.

And Symbol.Description? is folded into the string value of Symbol's uid.
By doing so, we can represent ES6 Symbol without extending current PropertyTable key; StringImpl*.

Previously, we checked isAtomic() or !length(). This guard can filter out EmptyUnique.

When no background-size is specified on the 2nd background layer, it takes the first instead of the initial value

Reviewed by Antti Koivisto.

Source/WebCore:

This patch fixes fill size support for 'initial' value.

Test: fast/css/background-layers-initial-size.html

css/CSSToStyleMap.cpp:
Add check for initial values and set fill size to initialFillSize() in this case (which is 'auto'). Previously, we were handling all non CSSPrimitiveValues the same way and setting the fill size type to SizeNone, which means no size (not 'auto').
Clean up the rest of the function (no behavior change).

rendering/style/FillLayer.cpp:

(WebCore::FillLayer::FillLayer):

Initialize m_sizeLength to SizeNone instead of calling initialFillSizeType(). There is no behavior change here. However, initialFillSizeType() was not supposed to return SizeNone.
Stop explicitly initializing m_sizeLength to LengthSize() as this is already what happens implicitly.

rendering/style/FillLayer.h:

(WebCore::FillLayer::initialFillSize):
Return FillSize() instead of FillSize(SizeNone, LengthSize()).
FillSize() is equivalent to FillSize(SizeLength, LengthSize())
which is resolved to 'auto'. SizeNone means no size which isn't
what we want as an initial value.

(WebCore::FillLayer::initialFillSizeType): Deleted.
(WebCore::FillLayer::initialFillSizeLength): Deleted.
Remove Individual initialFillSizeType() / initialFillSizeLength()
functions now that all caller use initialFillSize() instead.

Store MemoryCache's live decoded resources in a ListHashSet
https://bugs.webkit.org/show_bug.cgi?id=141051

Reviewed by Antti Koivisto.

Store MemoryCache's live decoded resources in a ListHashSet instead of
a linked list. The frequent operations are:

Add items to one end
Remove items from the other end or anywhere in the container by value

Using a ListHashSet instead of a manual linked list results in *much*
simpler / shorter code and is fast for all operations (faster than
linked list even for removing an given element from the container given
its value). The previous implementation required us to keep a lot of
pointers up-to-date, which was error prone.

This is a first step towards simplifying the MemoryCache implementation.
