Don't expose blink internal types from public headers
Mojo's -blink.h headers expose all the cool internal
Blink types which means they can't be used in public headers.
Instead use the -shared.h versions.

(There is a presubmit coming to prevent accidents like this)

Avoid clash between two NSAccessibilitySelectedTextMarkerRangeAttribute
There are two
NSString* const NSAccessibilitySelectedTextMarkerRangeAttribute =
    @"AXSelectedTextMarkerRange";
and in jumbo builds they will end up in the same translation unit
and trigger compilation errors.

This patch moves one of them to where its used which will prevent
the clash and let the compilation proceed.

Wrap X11 headers in ui/gfx/x/x11.h
X11 headers define a lot of common symbols and that will interfere
with other code, in particular in jumbo builds where the X11 headers
get wider visibility. This wraps common X11 headers in
ui/gfx/x/x11.h and adds the necessary symbols to the namespace x11
instead.

So instead of writing

XAtom prop_type = None;

you now write

XAtom prop_type = x11::None;

and the same for True, False, Status and a few others.

Too much code took upon itself to define 20 as the constant

be a single constant, in this case in the network URLRequest class.

Special-case the 'is2D' case in DOMMatrix::invertSelf
When the DOMMatrix is supposedly well-formed according to the 'is2D'

rather than the full matrix. This should avoid some numerical errors
sneaking in, breaking the 'is2D' invariant. It is probably a bit faster

Cleanup extraction of intervals for raster shapes
This restructures Shape::CreateRasterShape so that the raster data is

raster data. Move the size restriction from ShapeOutsideInfo to Shape.
The code is generally left as-was with some minor exceptions, like
using IntSize::Area() and using size types for |max_image_size_bytes|.
The console messages previously emitted for "too large" images are
dropped.
This makes error handling slightly easier and hopefully also improves

Removed IsOriginSecure clone and removed "using namespace"
Importing namespaces with "using namespace" can have surprising
results (which is why the coding standard disallows them).

This patch's main motivation is to remove a "using namespace content"
which made indexed_db code unable to distinguish between ::indexed_db 
and ::content::indexed_db in jumbo builds, but in the process it
was realized that the local IsOriginSecure was only partly used
and also seemed to be close enough to content::IsOriginSecure that
one of them should suffice.

There were two IsOriginSecure(). One in {anon ns}::IsOriginSecure() and
one in content::IsOriginSecure(). In mixed_content_navigation_throttle.cc
there are two calls to unqualified "IsOriginSecure()". One was 
supposed to resolve to {anon ns}::IsOriginSecure() and
the other one to content::IsOriginSecure().

After this patch both calls will go to content::IsOriginSecure().

Fix for reference counted variable being passed the wrong way
Passing pointers to reference counted variables as raw pointers in
bind is disallowed so this wraps it in base::Unretained like the
other types.

This was discovered while making the code able to be jumbo
compiled because in jumbo builds the type URLRequestContextGetter
was no longer a undefined forward declared type. As long as it
was a pointer to something "unknown" bind.h was fine with it.

Let jumbo use root_build_dir relative paths
Up until now include paths have been relative to the location
of the generated jumbo files. That can make paths rather long 
with many "../../.." in them.

In some circumstances, the paths are now too long for some
Win32 APIs (260 chars) so let us try with 
root_build_dir relative paths instead.

Rework computed style handling for 'width' and 'height'
getComputedStyle(...) for 'width' and 'height' would always return
'auto' for layout objects to which said property did not "apply" (by
some fuzzy heuristic.) This specifically broke for some SVG elements
where 'width' and 'height' apply (<rect>, <image> and <foreignObject>),
but is also wrong more generally - per CSSOM [1].

Rework the relevant parts of ComputedStyleCSSValueMapping::Get to
consider if the used value or the computed value should be used for the
respective property. The new helper
(WidthOrHeightShouldReturnUsedValue) replaces the old
WidthOrHeightPropertyAppliesToObject, while removing the explicit return
of an 'auto' identifier. 'auto' (or any other computed value) will now
be returned via ZoomAdjustedPixelValueForLength if the resolved value is
not the used value.

This is a behavioral change, and matches the behavior of Gecko.

Fold the old svg/css/getComputedStyle-svg-text-width-height.html test
into a new one that cover more (SVG) cases.

Reducing default jumbo chunk size from 100 to 50.
Bruce Dawson and I have mesaured what compile times you can expect
from different chunk sizes and it seems that the advantages of 100
over 50 is at best small so this patch reduces the default to 50.

It will mean that 100 becomes less likely to work without code fixing
since fewer people will compile with 100, but it should be an overall
better experience because smaller jumbo units means single-file changes
need to recompile less unchanged source.

Introduce ImageResourceContent::IntrinsicSize
Most non-layout/paint users that query the size of an image are
interested in the intrinsic size of the image (usually the physical
pixel dimensions.) This is currently achieved by calling the ImageSize()
method with a multiplier of 1.
Split the ImageSize() method into a part that extracts the size of the
image (if any) and one that applies the multiplier (and follow-on
adjustments.) This should allow a future cleanup where the scaling is
moved closer to the layer that uses it - i.e layout and paint.

This also reduces the type-impedance a bit since IntrinsicSize can just
return an IntSize (like Image::Size()) rather than passing through a
LayoutSize.

Fix size keyword comparison in CSSRadialGradientValue::Equals
Said function would ignore any size keyword or explicit size
specification if there was a shape keyword.
Adjust the comparisons so that first any explicit size checked, followed
by checking the size keyword and the shape value.

Also rewrite the if-ladder for the center point (|first_x_| and

Refactor <filter> invalidation to use the DOM structure
This changes the path used for invalidation of filter effects (SVGFE*)
from the layout tree to the DOM tree. This is done to allow invalidation
to work when the filter is not part of the layout tree. That change
will be done in a follow-up.

Also add casting helpers for SVGFilterPrimitiveStandardAttributes and

[LayoutNG] Update some test expectations for multicol.
When multicol support was introduced in NG, a lot of tests started to crash and
time out. I wanted to get rid of those as soon as possible, so I created a
separate bug report. It seems that all the crashes and timeouts introduced by
multicol are now gone.

Some caret-range-outside-columns tests still occasionally time out (they're
actually just very slow), but that doesn't seem multicol related.

Use a singleton invalidation set for self invalidations.
We used to create separate invalidation set instances for every single
invalidation set which just contains InvalidatesSelf(). That is, every
simple selector which only appears in the rightmost compound selector:

.a {}
#b:hover {}
#parent > .c {}

The invalidation sets for ".a", "#b", ".c", and ":hover" above are all
the same with only InvalidatesSelf() set.

Instead we can use a singleton invalidation set which is shared for all
such invalidation sets. If we later add more features to the set, we
replace the singleton with a new DescendantInvalidationSet instance
with InvalidatesSelf() set and add new features to that set.

This reduces memory use for invalidation sets from ~1MB to ~256kB on
facebook.com (see measurements in 773880).

Handle small/zero pixel densities correctly for img.naturalWidth/Height
ImageResourceContent::ImageSize has some special logic for clamping
image dimension that end up as "zero" (LayoutUnits) to one after having
been scaled by the multiplier it is passed.
This "correction" means that for images with a small/zero pixel density,
we'll end up returning 1 even when the density corrected dimension is
(integral) 0.

To handle this, pass 1 as the multiplier to avoid the dimension clamping
and perform the pixel scaling "manually".
While doing this also move the pixel density correction code to
HTMLImageElement, and get rid of the code from ImageResourceContent,
since it only used for <img> naturalWidth/naturalHeight.
This makes ImageResourceContent::SizeType only have a single value, so
remove the enumeration and the argument.

The bug was that if height was auto and there was no non-zero height content
inside, the multicol container would still become 1px tall, which was way too
much if there was nothing to contain.

Added four unit tests. Only the two using balancing used to fail. The two
without balancing are there for coverage.

[LayoutNG] Calculate overflow on multicol containers.
This gives us correct scrollbars, more or less.

Call UpdateLegacyMultiColumnFlowThread() a tad earlier, before calculating
overflow on the multicol container. It's the column set child that provides
overflow, so make sure that's calculated before calculating it on the parent.

That fixes two tests, but breaks two other tests. They break because of the
refs, which use absolutely positioned objects to cause a scrollbar (but that
doesn't seem to work in NG). But the actual tests now show scrollbars (which is
correct).

Improve SVGInlineTextBox::CalculateBoundaries accuracy
Make said method compute and return a FloatRect (which is then converted
to a LayoutRect in SVGRootInlineBox::LayoutInlineBoxes), as well as
using a float for the baseline.
This should make for more compact, hopefully faster, code (due to less
FloatRect -> LayoutRect and LayoutUnit -> float transitions.) Using a
float for baseline will also yield a small improvement in accuracy, and
is consistent with similar calculations.

Undef MAYBE* macros for jumbo builds.
In jumbo builds source files are merged and macros leak between
cc files. The easiest way to avoid that is to undef them after use.

This fixes a compilation problem with the MAYBE() macro which was

[LayoutNG] Don't round down when calculating balanced column height.
We need to take some extra care to make sure that the LayoutUnit we return,
multiplied with the number of columns, isn't ever so slightly less than the
content we are to put into the columns. Make it ever so slightly larger instead.
Example: If used column-count is 3 and the content we are going to fit is 100px
tall, we used to calculate a column height of 33.328125px. Now we'll return
33.34375px, which is larger than 33.333333333px, so that the content will
actually fit inside 3 columns, instead of 4.

Otherwise we'd get an overflow column with practically no content, and possibly
an unwanted scrollbar (when we add support for that).

Similar code in ColumnBalancer::ContentRun::ColumnLogicalHeight() for legacy
layout.

[LayoutNG] UpdateAfterLayout() on flow threads, column sets, spanner placeholders.
This is just for good measure. I noticed that the PaintLayer established by a
flow thread had zero size, which can't be good. Not that this seemed to cause

The UpdateAfterLayout() override in LayoutBlock now needs to be public, which
seems like a better idea than up-casting to LayoutBox when calling it.

[LayoutNG] Enable inline children special code for flow threads.
PlaceChildrenInLayoutBox() has special code for inline child fragments, to
basically skip them, unless we find floats. This wasn't executed for multicol.
This caused DCHECK failures and incorrect layout.

A few new tests now pass. One regresses, but that's because the test expected a
float to be at block offset 0, which it happened to be, since we didn't even
attempt to place it. Now we place it. We place it incorrectly, but at least we
place it. :)

[LayoutNG] Add NGPageLayoutAlgorithm.
This one is used when overflow-y is -webkit-paged-x or -webkit-paged-y.

Such declarations will trigger creation of LayoutPagedFlowThread in legacy
layout, very similar to LayoutMultiColumnFlowThread for multicol. The main goal
here is to produce a correct fragment structure (anonymous fragments for pages),
so that we don't get confused when writing them back to legacy layout. I got
some test regressions when trying to clean up some code, so I need to land this
first. Apart from that, I haven't made a huge effort to make it lay out
correctly.

It may be that this algorithm can also be used for printing, but we'll see.

One text autosizing test has started to fail, for some reason, but it seems that
it has started to fail similarly to constrained-and-overflow-scroll-ancestor.html,
so maybe it's a good sign. :)

Simplify ImageDocument::Scale() by eliminating the "page zoom" factor,
which is part of both the numerator and denominator and hence cancel
out. This removes that last user of the PageZoomFactor(...) helper

Don't use the content height of the multicol container. The columns may have

I expected this to make some of the old layout tests pass. Only one did, and
that one wasn't really a relevant or illustrating one. Most of the existing
test probably depend on line box fragmentation working (which still doesn't
work at all in NG), and that could explain why no relevant tests started to
pass. Added a new and straight-to-the-point test that uses a simple block.

Support jumbo for mojo generated code (-42 CPU minutes)
Mojo generates a lot of code that is expensive to compile and
compiling them through jumbo saves roughly 80-90% of that effort,
which is 42 CPU minutes on the reference machine (surprising that 
mojo code needs that long to compile).

42 CPU minutes is -7% of the current "fastest" compilation, or
-4.5% of current master use_jumbo_build=true. The wall clock effect
will be similar for a 4c/8t machine but smaller the more cores
the computer have.

This patch includes a change to jumbo.gni to handle targets 
with no sources, and streamlines targets with only one file, 
because both happen through the mojo template.

[LayoutNG] Framework and initial support for column balancing.
For now, just figure out how tall the content inside the multicol container is,
and divide by the number of columns, and make sure that the result doesn't
overflow the multicol container (by examining height and max-height (or width
and max-width if that's what's at the end of your favorite block axis)).

Previously we just used 42px if the column block size was unspecified, so this
is a slight improvement, as can be seen by the increased number of passing
layout tests. However, there are also some regressions because of this, because
it turned out that 42px was in some cases a better number than what we produce
now. We need to detect unbreakable content by traversing the fragment tree to
improve on this.

script blocking sheets are removed. As part of that update we do a

removed as part of removing a style element from the DOM. Updating
style and layout in the middle of a DOM operation is not safe.

Instead, update the fragment anchor position during the next safe

documentElement being removed while updating the style and layout tree,
but its parent pointer had already been set to null.

Inhibit scroll-to-anchor for embedded SVGs
Fragment anchors are often used for "spriting purposes" when using SVG
documents, so scrolling the referenced element into view could seemingly
randomly scroll the top-level document (if it was same-origin with the
sprite sheet.) This is usually not an expected or wanted behavior.
Inhibit scrolling for all the embedding cases. (It's uncertain whether
this ought to affect <iframe>s or not, but let's include those too for
now. For simplicity.)

While here, also remove the dependency on SVGDocumentExtension for the
trivial operation of getting the root element.

Revert behavior for non-scaling-stroke transform
https://codereview.chromium.org/2711503002 fixed getScreenCTM by
including the actual CTM from the element to the "screen" ("host"
coordinate space.) This of course also included the scale factor
contributed by any ancestor transforms. Including these transforms
however made evaluation of the non-scaling-stroke transform (the host
transform) unreliable, because of how that transform is "baked" into
the display list. (So if the host transform is sampled when it is
degenerate, all rasterization using that display list will produce
"weird" results - which will remain until an new display list is
recorded.)
Revert the computation of the non-scaling-stroke transform back
something akin to what it was previously until we can figure out a
better way to deal with this situation.

Less forcing of column flow flex children layout.
If the logical height of a child is intrinsic, we only need to lay it out if
there's a chance that the logical width of the flex container changed.
Otherwise nothing's going to change in there.

We do this by checking for kForceLayout, so that we don't risk descending into
deep subtrees just because some flex item sibling changed, for instance.

Don't include UseCounter.h from CSSParserContext.h and others.
public/platform/web_feature.mojom-blink.h is heavy.
Avoid it when possible.

Break the WebFeature defintion out of UseCounter.h and also make that
enum forward-declarable. There are quite a few translation units that
don't need to deal with UseCounter, just because they need to name a
web feature. And then there are also some places where we just need to
have the type forward-declared, such as in CSSParserContext.h

This reduces the number translation units that depend on UseCounter.h
by about 1601 compilation units, which is ~56%.

It seems that most translation units that include UseCounter.h really
need the WebFeature definition as well, so at least for now, it will
be included there.

Performance test with deeply nested column flex containers.
In this teste there's a (rather) deeply nested subtree of column-flow flex
containers. The root of this subtree is itself a flex item in a row-flow
container. It has a sibling item whose child changes width, without affecting
the flexed size of the deeply nested subtree. This shouldn't require the
subtree to be re-laid out, but it currently does get re-laid out, thanks to the
fix for bug 752078.

Ignore <input> and <textarea>'s user-select styling
Background:
The CSS spec says that user-select does "selective inheritance",
see https://drafts.csswg.org/css-ui-4/#propdef-user-select.

<input> and <textarea> are two elements that are affected
by this. These elements should not inherit user-select from
parent elements.

Fixed problem:
<input|textarea readonly|disabled> could inherit
"user-select: none".

This regressed because
https://chromium-review.googlesource.com/570246
removed input|textarea's default user-select styling.

Solution:
Make all text controls always selectable. This is done in
LayoutTextControl::AdjustInnerEditorStyle.

Interoperability note:
<input readonly style="user-select: none"
value="Chrome 61 cannot select this.">. This CL fixes
this by ensuring that all text fields (i.e also readonly fields)
are always selectable (no matter user-select styling).

In other words, <input> and <input readonly> now behave in
the same way (both always allow selections) which aligns
us with Firefox and Edge.

offsetParent fails to consider continuations when searching for parent.
Block-level objects can have inline parents, but this triggers the
insertion of anonymous boxes and continuations, which offsetParent()
currently doesn't understand.

This change lets offsetParent() understand continuations better.
If an anonymous continuation is encountered when finding ancestors,
it will use the split inline as the ancestor, and continue searching
from there.

[LayoutNG] Implement NG support for the line height quirk.
This cl implements NG support for the line height quirk.  There
are some deviations from the behavior of the old layout code:

- inline boxes with margins in the inline direction will now cancel
  the quirk, previously only borders and padding caused this.  This is
  in line with Gecko and Edge.

- in the existing layout engine, if there's a line break between two
  replaced elements separated by whitespace, the whitespace at the end
  of the line is preserved, in turn causing the line height quirk to
  be cancelled.  The whitespace preservation appears to be in
  violation of CSS 2.2, 16.6.1, and does not exist in NG.

A few test cases had to be altered to accommodate these differences.

Make sure to include traits before testing them in tests.
It's possible to check traits without including their specialization
or doing an implicit instantiation but then you get the default
values which can be wrong (or you would not have had a specialization).
In jumbo builds this is noted because first you get an implicit
instantiation and then an explicit instantiation which is a C++ error.

Fix is to make the explicit instantiation before any implicit
instantiations can happen. I do wish this error wasn't so invisible. It's
the third or fourth detected through jumbo builds.

Re-attach whitespace children when removing DOM nodes.
When the display type changes for an element in the DOM tree, the
WhitespaceAttacher would re-attach whitespace siblings appropriately
when traversing the re-attached element.

When a DOM node is removed from the tree, there will be no layout tree
rebuild. Or, at least, the removed node will not be encountered by the
traversal to trigger a re-attachment of any following whitespace nodes.

In order to fix that, introduce a hash set which contains elements
which had one of their layout tree children removed since the last
layout tree update. In the next UpdateStyle mark these elements for
layout tree rebuild and let the WhitespaceAttacher check if any of its
whitespace children needs to be re-attached.

Moved the call to UpdateLegacyMultiColumnFlowThread() further
down. Apart from making sense (nice to have written back the size of
the multicol container before updating the flow thread), this became
necessary now, because otherwise ValidateColumnSets() would nuke the
logical width of the flow thread, now that the flow thread gets its
logical width set earlier.

[LayoutNG] Unbreakable content in block fragmentation.
This introduces limited support break-inside:avoid on in-flow block-level
elements. After layout, if we discover that we need to insert a break in front
a node, in order to honor break-inside:avoid, drop the fragment and retry at
the start of the next fragmentainer.

The constraint spaces now need to know the full fragmentainer block size, in
addition to what they have available. It's only when the available size is less
than the full fragmentainer size, that we can break before some node. Otherwise
there'd be no progress, and we'd end up with an infinite number of empty
fragmentainers.

Since I wanted to DCHECK that we only break before the first fragment of some
node, and therefore needed IsFirstFragment(), I moved that function along with
its friends from the anonymous namespace of ng_block_node.cc to a new
ng_fragmentation_utils.h file. There's some uncertainty as to how to treat
non-box fragments here, but we can figure that out later.

Always rebuild layout tree for shadow root when host is rebuilt.
We tried to do a light-weight search for the first in-flow or text
child of the shadow root when shadow root children didn't need a
rebuild. This was done to make the WhiteAttacher point to the correct
text node when re-attaching the ::before element.

This code did not properly handle slots and insertion points. Also,
supporting display:contents for ::after means we will have to traverse
shadow root children from its last node until we find the first in-flow
to properly attach a space inside an ::after element.

For simplicity, and correctness, walk the shadow root children using
RebuildChildrenLayoutTrees() instead.

the value returned from the constraint space's FragmentainerSpaceAvailable()
directly. Renamed that method in both the constraint space and the builder to
FragmentainerSpaceAtBfcStart(), to make it clear that this value doesn't
necessarily return the space available to the block currently being laid out.

Added FragmentainerSpaceAvailable() to the block algorithm instead, and also

Rework normalization in LayoutSVGInlineText
When performing (whitespace) normalization in an OriginalText override,
we miss normalization when the layout object has its text content
updated.
Perform the normalization in the SetTextInternal override instead to
cover the text-content-update case as well.

[LayoutNG] Detect breaks that occur at the exact start of blocks.
Such breaks used to go unnoticed and cause misery and assorted unpleasantries.
Upgraded test expectations. Added a unit test.

As long as we haven't both got an in-flow child that broke AND exceeded
available fragmentainer space, we need to continue and lay out its siblings. A
block of zero height at a fragmentainer boundary actually belongs in the former
fragmentainer, not the latter. A consequence of this change is that even
non-zero height blocks that start at a fragmentainer boundary gets a
zero-height fragment in the former fragmentainer, before it continues in the
next fragmentainer. We may want to avoid this, but I'm not sure what's more
correct yet (or if it matters at all).

Avoid implicit conversion to CGRect and CGSize.
Implicit conversion to CGRect and CGSize can create extra conversion paths
(if known) between various rect/size types. Such extra conversion paths
can make the compiler fail to compile because of ambiguity.

Since conversions between CGRect and CGSize and internal types are lossy
both ways (float <-> int), it's best to avoid them anyway except when
they are really needed so this patch makes the cast operators explicit.

Short term, the implicit conversions break jumbo builds since the compiler
there knows "too much" and gets confused.

Adjustments for LayoutNG in LayoutBlockFlow line layout.
LayoutNG ignores LayoutMultiColumnFlowThread objects, so that the DOM
children of a multicol container become actual layout children of said
multicol container (on the NG side), without any intervening flow
thread block. However, the flow thread is still created even in NG (to
be able to paint and hit-test using the legacy layout structure), so
when NG invokes the legacy engine to lay out lines, we need to be able
to stop walking the ancestry when reaching the flow thread.

This fixes a bunch of crashing tests. They will now either pass or
fail (without crashing) instead.

PlzNavigate: Fix multiple extra_headers in LoadUrlWithParams
NavigationControllerImpl operates on LoadURLParams, which state
"Extra headers for this load, separated by \n.", and on
NavigationEntryImpl, which state "Extra headers (separated by \r\n)
to send during the request". However, there is no conversion
from one form to the other, instead the extra headers are passed
verbatim.

This is not an issue when PlzNavigate is not enabled, because there
are more conversions on the way to and from the renderer, and things
end up working anyway. However, the shorter path of PlzNavigate
makes code further down choke on improper data when more than one
header is passed.

Fix by converting LF to CRLF when moving from LoadURLParams to
NavigationEntryImpl, and by adding a second header to a bunch of tests
that only sent one extra_header, thus not showing the problem.

Empty files should not succeed in loading (as WebVTT)
Empty files will naturally not have a valid signature, so should fail
the signature check. When there's no data, the loader will not get any
DataReceived() callback, and hence not create a VTTParser. The
NotifyFinished() callback only checked for any error on the resource,
and would flag success if there were no resource error.
Check for the presence of a parser to detect the case where there's no
data and infer failure from it.

Also move the flush of the VTTParser first in NotifyFinished() since
it could, in rare cases, end up setting |state_| to kFailed.

Don't compute pseudo element style on other pseudo elements.
Nested pseudo elements are not allowed. We tried to match selectors for

Don't request style on element when pseudo element style is null.
StyleForLayoutObject returns nullptr for ::before and ::after pseudo
elements when the pseudo element should not generate any boxes. This
caused us to incorrectly request OriginStyleForElement as a fall-back
which caused DCHECKs to trigger when trying to match rules against the
PseudoElement.

Instead, call OriginalStyleForElement as a fall-back in
CustomStyleForElement for elements which do have custom style callbacks
but don't need a specialized CustomStyleForElement.

Avoid having two g_unique_id in blink/platform
In jumbo builds the two g_unique_id clashed so to avoid having to
exclude one of the files from jumbo builds, it's better to rename them.

With this patch they will be g_unique_media_stream_component_id and
g_unique_media_stream_descriptor_id instead. As a bonus that should help

Avoid using "using namespace ..." in global scope
With jumbo (unity builds, merged translation units) a
"using namespace WTF" or "using namespace Unicode"
statement intended for just the local translation unit will affect
many other translation units which causes various issues.

There is also (with the current implementation of jumbo) a warning
about such usage that will prevent things from compiling.

Support all of HTML's character entities in WebVTT
This updates the VTTTokenizer to align with the updated WebVTT tokenizer
steps:

 https://w3c.github.io/webvtt/#html-character-reference-in-data-state

and

 https://w3c.github.io/webvtt/#html-character-reference-in-annotation-state

The old states for handling "escapes" are removed, adding new ones per
above, for invoking the HTML parser's entity matcher.
A new WEBVTT_SWITCH_TO operation is also added so that state transitions
can be performed without advancing the input position. (Matches
mechanics of the HTML parser.)

The WPT test webvtt/parsing/cue-text-parsing/tests/entities.html is
updated since it had an incorrect expected result for the "&notit;"
case.

Old, now incorrect and/or redundant, tests for entities are removed.

Make SMIL interval position calculations more resilient
When 'dur' is mutated, all dependent state is not updated at once, but
rather lazily. This means that we can get into an inconsistent state
where some timing parameters have been applied while some have not, and
code that uses - and thus realizes - the state changes will be first to
observe them. This can for instance lead to an interval position of NaN
being computed, which would wreak havoc when computing values.

For the specific case, we'd first get an 'indefinite' simple duration
and compute an interval thereafter. When 'dur' is then modified to a
finite value the simple duration will not be updated until the next
frame is computed (triggered by mutation of 'end'), leaving us with
a valid/finite simple duration but an infinite interval. (This then
results in arithmetic with Inf, yielding a NaN value for |percent|.)

Properly updating all the interval computation state on mutations is a
somewhat involved task, so paper over it for now by computing the (last)
active duration differently depending on the case we're in. While this
change is a bit of a workaround, it should be a perfectly reasonable
change on its own.

[LayoutNG] Skip siblings preceding the first break token.
When we resume layout in a next fragmentainer, assume that all siblings
preceding the one associated with the first break token have been finished.
Assuming the opposite - that all preceding siblings needed layout - caused
infinite loops.

Example:
<div style="columns:5; column-fill:auto; height:60px;">
    <div id="child1" style="height:100px;"></div>
    <div id="child2" style="height:100px;"></div>
</div>

After the first column, we'll have an unfinished break token for #child1, which
is what we'll resume with in the second column.
After the second column, we'll have a finished break token for #child1 and an
unfinished break token for #child2.
After the third column, we'll only have an unfinished break token for #child2,
since we skipped #child1 (it was finished).
The fourth column obviously only contains #child2. We shouldn't start at
#child1 just because it has no break token, or we'll get an infinite loop.

Setup AttachContext correctly when attaching pseudo elements.
AttachContext.previous_in_flow was not set up correctly when attaching
pseudo elements. That caused incorrect whitespace attachment in some
cases. In order to do this, the AttachContext for children is set up in
Element instead of ContainerNode as ::before and ::after are attached
in Element before/after ContainerNode::AttachLayoutTree.

I have separated the creation and attachment of pseudo elements.
CreatePseudoElementIfNeeded now only creates the pseudo element.
Previously pseudo elements were sometimes attached as part of style
recalc, at which point we don't have a previous_in_flow to pass in.
This is also good for our goal of separating style recalc and layout
tree construction completely.

We still create pseudo elements when attaching a layout tree if these
pseudo elements are inside a subtree being (re-)attached. When we start
constructing ComputedStyle for elements in sub-trees being re-attached
in RecalcStyle instead of LayoutTreeBuilder, we can fully rely on
pseudo elements being generated for RecalcStyle.

The modified test expectations are actually a revert of what was
changed when landing the WhitespaceAttacher.

Don't rely on the cached 'local' flag when resolving <use> target
Since the document URL can change between a <use> 'href' is set, and the
actual element reference is resolved (looked up by id), the notion of
being "local" to the document can change during this window as well.
To avoid this, we need to re-evaluate the "is local" state before
resolving the element reference. This appears to match what other UAs
are doing (but they could/do differ in other ways.) Keep the cached
"is local" state and use where applicable to avoid the full URL compare.

Invalidate matched properties cache when registering custom properties.
Not forcing SetStyleInternal in Element::RecalcOwnStyle triggered a
DCHECK fail for (!!value == !!parsed_value) in
SetResolvedInheritedVariable(). We were hitting the matched properties
cache to re-use the custom properties from the style recalc before and
after property registration. The property registration made the custom
property value invalid due to the given syntax.

It's possible this should be detected as a style propagation change in
RecalcOwnStyle (ComputedStyle::operator==), but clearing the matched
properties cache seemed like a good idea since all style is
recalculated on property registration anyway.

[LayoutNG] Copy multicol layout back to the LayoutObject tree.
Stitch fragments generated from the same layout input node
together, so that the flow thread based multicol implementation
in legacy layout can perform painting, hit-testing and other
layout tree read operations like before.

The position will only be updated when at the first fragment for
each node. The position of subsequent fragments are only relevant
to LayoutNG. For legacy layout they just contribute to the
block-size of the LayoutObject. Currently, the position will
still be mostly wrong, unless the object starts in the first
column.

One change to the break tokens was necessary: the final break
token also needs to set its used block size, just like the
preceding tokens, so that clients can tell that it's not the
first fragment of some node.

Locate the correct flow thread for spanners and out-of-flow objects.
LayoutFlowThread::LocateFlowThreadContainingBlockOf() used to just
give up if the nearest ancestor flow thread of some object wasn't the
containing flow thread.

The machinery that maintains the special-objects
(LayoutMultiColumnSet, LayoutMulticolumnSpannerPlaceholder) for
multicol still needs to ignore out-of-flow objects and spanners,
though, so I moved the check for this from
LocateFlowThreadContainingBlockOf() to
FlowThreadDescendantWasInserted() and
FlowThreadDescendantWillBeRemoved().

Checking on the paint side whether page logical height is known is
no longer necessary.

[LayoutNG] Bring back native support for multicol.
Still missing: Copy data back into the LayoutObject tree.

Some layout tests now fail, since we're not using the legacy engine to lay out
multicol. Quite a few crash or freeze, too.

Also brought back some of the unit tests. They needed some changes, because of
the following:

1. We now create a fragment for each column, from an anonymous constraint
space. I.e. we have one more level of fragments, and it's the column fragments
that have their inline offset shifted to the correct column, rather than
setting it on the first child block, which is what we did last time these tests
worked.

2. Mistakes introduced when converting test to using setBodyInnerHTML() rather
than building the layout trees programmatically:

Saturated arithmetic when calculating multicol preferred widths.
With sufficiently large column-gap and high enough column-count, we'd
integer-overflow and end up with a negative gap_extra result, which is a value
that contributes to the preferred min/max preferred logical widths (which
therefore also could become negative). Let all values involved be of type
LayoutUnit, so that we get saturated arithmetic enabled.

Let LayoutView::StyleWillChange handle viewport invalidation.
Make sure we only do a single SetStyle for viewport ComputedStyle
to which we propagate certain documentElement/body styles. That way we
can do style invalidation diffing on SetStyle. The invalidation will
now be done on LayoutView::StyleWillChange instead of invalidating
LayoutView from LayoutBox::StyleWillChange for documentElement and body
changes.

The LayoutView invalidation does still use a limited repaint based on
propagated background changes.

Propagate style to viewport after style recalc.
Since we are now propagating up to the viewport style and don't do any
inheritance after propagation, we can postpone the propagation until
after the style recalc has finished. That means we only have to call
StyleForElement on html and body elements once. It also means we can
remove the code to clear animation update from
InheritHtmlAndBodyElementStyles().

InheritHtmlAndBodyElementStyles() has been renamed to
PropagateStyleToViewport() which better explains what the method does.

The rem unit style recalc still needs to be triggered right after the
documentElement has been recalculated, but that code is moved to
the StyleEngine called from Element::RecalcOwnStyle().

Apply :placeholder-shown and :read-write changes on input type change.
Whether :placeholder-shown, :read-only, and :read-write matches an html
input element depends on its type. Apply changes on type attribute
changes accordingly.

The placeholder text and visibility had to be updated sychronously,
otherwise the pseudo invalidation happens before the placeholder

No need for recalc on viewport propagation.
Before the fix for issue 732349, we relied on propagation from body to
viewport to affect the computed style of the root element which was
handled through a subtree recalc after viewport propagation. This is no
longer necessary. In fact, when rtl was specified on body, but the
computed style of html was ltr, InheritHtmlAndBodyElementStyles would
always trigger a subtree recalc, which would happen every frame we had a
style recalc.

There's a hope this will fix performance issue 739133.

I think that InheritHtmlAndBodyElementStyles can be made into a
PropagateStyleToViewport method which can be called at the end of
style recalc to avoid calculating html and body style twice. I'll try
to do that in a separate CL.

Remove rulesets used for style sharing.
After style sharing code is removed, we no longer need the sibling and
uncommon attribute rulesets to reject style sharing. This also means
RuleFeatureSet no longer needs to be traced, so some oilpan cruft could
be removed.

The StyleEngine API UsesSiblingRules() relied on the size of the sibling
ruleset, but it was only used as what looked like an optimization for
:empty selector updates where :empty is found in non-rightmost compound
selectors. However, the presence of :empty itself would add a sibling
selector in the previous code, and :empty in non-rightmost compound not
followed by an adjacent selector would only have de-generate cases like
":empty span" which could never match anything, or ":not(:empty) span"
which would always be true if the whole selector matches. Therefore, it
makes sense to just drop the API/check.

Let CalculatePaginationStrutToFitContent() figure out the strut all on its own.
Remove the strut_to_next_page parameter, and let it calculate it on its own.

This is a preparatory patch for supporting repeated table footers. That will
break the "space left" == "pagination strut" invariant. Actually, this wasn't
truly an invariant even prior to this CL, because the next fragmentainer isn't
necessarily tall enough to hold the content (which will result in a pagination
strut larger than the amount of remaining space).

No behavior changes intended.

`gail:atk-bridge`, while in fact, the module to look for is
`atk-bridge`. On systems having a more complex content for GTK_MODULES

Revert "Make border width rounding visible to js via getComputedStyle."
This reverts commit e87da780e04bf05f5ae863d7fda517ee6c03d534.

Reason for revert: This fix is a spec violation, and the previous behavior was more correct. A slightly inaccurate representation (off by less than 0.02px) is better than clamping it to 1px.

Original change's description:
> Make border width rounding visible to js via getComputedStyle.
> 
> CL (https://chromium-review.googlesource.com/c/525536/) moved rounding of border 
> widths to the painting stage, hence rounding is no longer visible in js via 
> getComputedStyle. This cl makes rounding visible again to users via getComputedStyle.
> 
> This cl contains the following changes
> * Implemented a ZoomAdjustedPixelValueWithRounding method.
> - This method is the same as ZoomAdjustedPixelValue except that it
> rounds pixel value to 1 if original value is between 0 and 1.0.
> * Changed ComputedStyle for border-[top|right|bottom|left] to use
> ZoomAdjustedPixelValueWithRounding so that getComputedStyle will
> display rounded pixels for these properties (and also border-width that
> is a shorthand of these 4 longhand properties).
> * Changed a layout test.

Always relayout when an object gets or loses a PaintLayer.
This rids us of some crufty code, and also fixes bugs. The approach was also
broken for multicol, because we started UpdatePaginationRecursive() in the
middle of the tree without looking for a containing flow thread (pagination
layer). This would result in the new layer erroneously not becoming paginated.

Also had to update a unit test, to satisfy its requirement that the style change
won't trigger layout.

Support jumbo builds in core unit tests (except editing)
This patch makes the build system for core unit tests support jumbo
builds (unity builds) which saves roughly 60 CPU minutes (5% of the
build time) on my computer. Currently jumbo is by default disabled so
this will have no direct effect unless you have
  use_jumbo_build = true

Make blink/modules support jumbo compilations (-60 CPU minutes)
Compiling browser code in blink/modules currently use
about 80 CPU minutes. That is about 7% of the total compilation time.
If you use jumbo compilation (merge many files into a single
translation unit) that time drops to about a fifth of that.

There are also unit_tests in modules that will be jumbofied in
a different patch.

Avoid "using namespace blink" in global scope
With jumbo (unity builds, merged translation units) a "using blink"
statement intended for just the local translation unit will affect
many other translation units which causes various issues.

There is also (with jumbo) a warning about such usage that will prevent
things from compiling.

Without this patch this file will have to be manually excluded from
jumbo builds and I am trying to avoid such exclusion lists for

blink/platform: Be explicit about namespace testing to not mix it with blink::testing
There are two namespaces named testing used in Blink unit tests, one
from gtest and one internal helper namespace. If both are visible then
the gtest testing namespace won't be used unless prepended with ::, as

The condition "show I-beam if we have a non-empty selection"

We should show an I-beam when:

Avoid race at shutdown between browser process' IO thread and GPU thread
Background:
- When the GPU thread is *in-process* it runs inside the browser process.
- GpuChildThread is a ChildThreadImpl and a IPC::Listener.
- When GpuChildThread sees an error (or shutdown) of its IPC channel,
  it quits its message loop (= stops the thread).

Problem:
The browser process' IOThread calls InProcessGpuThread::StopSoon()
while the in-process GPU thread destructs itself.

When InProcessGpuThread::StopSoon asks for task_runner() the in-process
GPU thread has - sometimes - already destructed itself and its
MessageQueue. The IOThread then sees task_runner() == null and crashes:

[FATAL:ref_counted.h(484)] Assert failed: ptr_ != nullptr.
0 base::debug::StackTrace::StackTrace()
1 base::debug::StackTrace::StackTrace()
2 logging::LogMessage::~LogMessage()
3 base::Thread::StopSoon()
4 base::Thread::Stop()
5 content::InProcessGpuThread::~InProcessGpuThread()
6 content::InProcessGpuThread::~InProcessGpuThread()
7 content::GpuProcessHost::~GpuProcessHost()
8 content::GpuProcessHost::~GpuProcessHost()
9 content::BrowserChildProcessHostImpl::TerminateAll()
10 content::BrowserProcessSubThread::IOThreadPreCleanUp()
11 content::BrowserProcessSubThread::CleanUp()
12 base::Thread::ThreadMain()
13 base::(anonymous namespace)::ThreadFunc()

Solution:
If a thread runs in the browser process, only Thread::Stop should
stop its message loop. Otherwise, QuitWhenIdle could race Thread::Stop.

Adjust svg/animations/animate-linear-discrete-additive*.svg
In these tests we want to sample animation values at a certain point in
time. We are however sampling the animations at the next frame that is
painted - at which point the timeline may have advanced, and hence we
sample at t+<framedelay> (or thereabout) instead. Currently this works
"fine" because the first animation frame follows special scheduling
rules, making sure the timeline won't advance within this time window.
Rather than relying on this, just pause the timeline instead.

Be explicit about namespace testing to not mix it with blink::testing
There are two namespaces named testing used in Blink unit tests, one
from gtest and one internal helper namespace. If both are visible then
the gtest testing namespace won't be used unless prepended with ::, as

When using "using namespace Foo" at global level you will

Also, global using namespace statements will, with the current

Handle re-entrant AttachLayoutTree for the same node.
Lazy whitespace re-attachment introduced tracking of the last seen in-
flow box in AttachContext. We have three places where we may end up
calling AttachLayoutTree from AttachLayoutTree for the same element[1]
causing re-entrancy issues for AttachContext. The AttachContext would
keep a pointer to the LayoutObject created by the outer AttachLayoutTree
while that may have been deleted by the inner AttachLayoutTree.

Here we store the passed-in AttachContext on a SyncReattachContext stack
and pass it, with the previous in-flow restored, when re-entering
ReattachLayoutTree().

[1] This typically happens when we find out that a resource won't load
while attaching the layout object and we immediately decide to render
fallback content.

Scripts for unity/jumbo (default disabled) compilation.
To speed up compilation times, jumbo allows files to be compiled
together. This is a well known method ("unity builds") to both
compile faster and create a poor man's "full program optimization".
For Chromium we are only interested in the compile times.

This patch includes the basic scripts that do the source file merging
and changes Blink Core to use those scripts. If the gn configuration
includes: use_jumbo_build = true then Blink Core will use jumbo
compile. Otherwise it will compile as usual.

The expected speedup from using Jumbo on Blink Core (and nothing else)
is about 17% of the content_shell+blink_tests compilation CPU
time. This is about half an hour for people building with an ordinary
computer, but less both in percentage and minutes if using some kind
of build accelerator like goma.

Implement lazy (re-)attachment of whitespace.
The existing implementation of re-attachment of whitespace nodes had
performance issues because it tried to re-attach whitepace nodes as
early as possible, leading to multiple re-attachments of the same node
and multiple sibling-walks past the same out-of-flow elements.

Instead, this CL stores the last seen text node in a new
WhitespaceAttacher object and delays the re-attachment of that text
node until we know its need for a LayoutObject for the current layout
tree rebuild. In particular, we don't re-attach the whitespace node
when previous siblings are/become display:none or out-of-flow.

Contrary to what last_text_node did, the WhitespaceAttacher persist
the last seen text node in the flat tree order and across
display:contents and slot/content element which fixes various
correctness issues in addition to performance issues.

In addition to the last visited text node, we also store the last
seen display:contents element and only walk the display:contents
subtree when needed to find its first in-flow whitespace descendant.

Separate initial style and viewport/ICB style.
We store the initial containing block/viewport style on the Document
node. This style includes properties propagated from body/html like
writing-mode and overflow. It also sets things like z-index to a non-
auto value to establish a stacking context.

The problem was that this ComputedStyle was used for inheriting values
down to the root element as well, which is incorrect. The root element
should inherit initial values.

Instead, split StyleForDocument into InitialStyleForElement and a
StyleForViewport which applies viewport specific properties on top of
the initial values. Then use InitialStyleForElement as the style to
inherit from for the root element.

A bunch of writing-mode tests are modified to apply writing-mode on the
html element instead of body. The code change aligns with the spec and
how Gecko behaves by not propagating the writing-mode on body to the
html element. The intention of the modified tests was to have the effect
of setting the same writing-mode on the html element.

Hold global GC heap lock while making audio thread access.
For auxillary threads that rarely need to gain access to another
thread's GC heap, we have to ensure that this happens while the
heap-owning thread isn't concurrently GCing the heap. Otherwise there
is the possibility that heap objects might be relocated or mutated
while the auxillary thread tries to access.

A CrossThreadPersistent<T> (CTP) ensures reference liveness across
threads, but isn't sufficient to handle the wanted exclusive access
after a non-attached thread has deref'ed the persistent. So, for
this to happen, keep the global CTP lock while accessing a heap
object during offline audio rendering -- it specifically accessing
heap objects while a GC runs. As all GCs hold the lock on the global
CTP region while they run, this ensures exclusion.

It is clearly desirable to have all heap access be under the control
of the heap-owning thread, and threaded code should try hard to avoid
accessing another thread's heap objects. The CTP global lock is the
mechanism to use when that isn't practically feasible -- feel free to
add a "TODO(foo): avoid using" next to any instances that you end up
introducing.

As regards audio thread cross-thread usage, the code needs auditing to
check if there are other places where setting up this CTP lock is
required.

Element::ClientQuads() needs to take transforms into account.
In LayoutGeometryMap, when there's a non-uniform step (e.g. when inside
multicol), we fall back on doing it the slow way, i.e. we involve
LayoutObject::MapLocalToAncestor(). The mode flags initially passed from
ClientQuads() will just be echoed here, so we need to make sure that

Update HasOverflowClip for body after style recalc.
The HasOverflowClip flag on LayoutBlock is updated as part of SetStyle,
but for body, the flag may need to change as a result of changing the
overflow property on the root element.

This CL always updates the flag for body after a style recalc. It's
only strictly necessary to do this if the root element is recalculated
and changes overflow between visible and a non-visible overflow, and at
the same time, the body element does not need a style recalc. Those
checks would complicate the code with little gain, so left to be done
unconditionally.

This fixes scrollingElement.html and HTMLBody-ScrollArea_quirksmode.html
in wpt/cssom-view. The latter had a bug that it didn't clear the
"scroll" values set to check if overflowY could be set, which caused a
subsequent test to incorrectly fail in both Blink and Gecko.

If min/max widths are already dirty during layout, don't recalculate.
Min/max widths are recalculated right before layout if they are dirty, but only
on those objects that actually need it, even if they are marked dirty. If the
object doesn't need min/max widths to figure out its own size, and no ancestor
needs this information either, the flag should just be left on indefinitely.
It's a waste of time to recalalculate the min/max widths for such objects, and
just leaving them dirty instead will also help the marking machinery cut off
earlier, since it will walk the containing block chain until it finds something
that's already marked.

If we get to layout and the flag is still set, it has to mean that nobody cares
about the min/max widths. This is a speculative fix for bug 732703, that
restores to the behavior we had prior to
https://chromium-review.googlesource.com/c/527640/ .

Need to dirty min/max widths on certain children, regardless of entry-point.
It doesn't matter whether it's during layout or not that we decide to
recalculate the min/max widths. If the min/max widths of a child is known to be
affected by changes in the containing block, we need to recalculate them
regardless of that.

This got broken by https://chromium-review.googlesource.com/527640 . It used to
work prior to that change, because then, dirty bits on the child of the
shrink-to-fit container were accidentally left behind from a previous layout
pass, so that min/max widths got properly recalculated the next time its parent
got marked dirty.

probably never worked before, though.

Also shortened the name of a parameter, to prevent the code formatter from

Better handling of min/max widths that depend on the containing block.
This is about how we behave when NeedsPreferredWidthsRecalculation()
is true. This is a rather rare situation, and also an unfortunate one,
since min/max width calculation should be strictly bottom-up.

If we mark min/max widths of an object as dirty, we need to guarantee
that they're actually going to be recalculated. Otherwise, if the
object is left around with dirty min/max widths, it will block
subsequent min/max dirtying of any descendant. We also need to make
sure that if we mark min/max widths as dirty due to
NeedsPreferredWidthsRecalculation(), we also need to mark the min/max
widths of every child with the same issue as dirty, recursively, since
any layout change may have affected the min/max widths there too.

Documented NeedsPreferredWidthsRecalculation(). Added one test that
has been failing for ages, and one that started to fail because of the
bug referenced. Both pass now.

No longer let 0 mean that fragmentainer height is unknown.
For multicol, PageLogicalHeightForOffset() would normally figure out what to
return by consulting the flow thread, which would find the appropriate column
set, which in turn would find the appropriate fragmentainer group and return
its height.

We used to treat a 0 value as "unknown" most of the time (but there were also
cases where we'd accept it as a column height). We now always have to call
IsPageLogicalHeightKnown() first to tell whether it's known or not. This is
reasonable, since the calling code always has to act upon the situation of not
knowing the height (typically skip some steps, since fragmentation is
impossible until height is known).

It is now forbidden to call PageLogicalHeightForOffset() if height is unknown
(there are DCHECKs). The height is unknown in many cases in the first multicol
balancing pass. The height will be known once we have made a column height
estimate. It doesn't have to be the final and correct height. This CL doesn't
change anything in that regard, but now we are required to be sure that we
have some clue at all before dealing with fragmentainer heights.

MultiColumnFragmentainerGroup now has a flag that tells whether the logical
height is known or not. We need the flag, because the logical height may
actually end up as 0, e.g. when a multicol container just has zero-height
content, or when the multicol container itself has a specified height of 0.
This unclamped height will be used as block progression for the column row,
which will contribute to the final height of the multicol container. The
actual column height will be clamped to not be less than 1px. This is in
accordance with the spec [1]. We previously used to treat truly zero-height
fragmentainer groups as having an unknown height in some parts of the code,
while in other parts of the code we'd just accept it and end up dividing by
it (to convert a flow thread offset to a column index, for instance).

This is a clean-up CL that happens to fix bugs.

Less duplicated code between AvoidsFloats() and CreatesNewFormattingContext().
In general there shouldn't really be any need for both. We could just remove
AvoidsFloats() and keep CreatesNewFormattingContext(). But then again, it might
be considered weird to say that replaced content creates a block formatting
context. So let's keep the both of them for now.

However, the following rule should always apply: If the object creates a new
formatting context, it implies that it also avoids floats. That's the reason for
declaring LayoutBlockFlow::AvoidsFloats() as final.

Furthermore, the only kind of LayoutBlock-type objects that DOESN'T create a
new formatting context, are certain LayoutBlockFlow (block container) objects.
So move the checks over from LayoutBlock to LayoutBlockFlow. Keep a virtual
true-returning CreatesNewFormattingContext() in LayoutBlock. We could actually
consider removing this, but there are 2-3 call sites that currently need it.

This CL causes a couple of minor rendering differences: Previously, HR elements
were told to avoid floats, but not to establish block formatting contexts.
Let's be consistent and return true for both. This makes us more compatible
with Edge. Test included. Turning HR elements into true block formatting
contexts also affects margin collapsing. Its top and bottom margins no longer
collapse. Had to make a change to the default style sheet for HR inside
SELECT because of this. Inside SELECT, HR loses its borders, so that its top
and bottom margins would previously collapse, but not anymore, now that it
establishes a block formatting context. To cancel out any rendering difference,
reduce margins in this particular case.

Similarly for RT (ruby text). LayoutRubyText objects are repositioned after
layout, which essentially requires them to contain all child floats, i.e.
establish a new block formatting context. Previously they achieved a
quasi-formatting context by returning true from AvoidFloats(). The screenshot
test fast/ruby/float-overhang-from-ruby-text.html would fail spectacularly if
they exposed child floats to their sibling ruby base. That test expectation
still requires a tiny update to its layout tree dump, though.

This CL also makes CreatesNewFormattingContext() return true for tables,
flexboxes, grids, and anything blocky that isn't LayoutBlockFlow. This
shouldn't be a web-exposable change, though, since no non-LayoutBlockFlow types
can contain float children (e.g. a float inside a table would have to be
wrapped inside either a table-cell or a table-caption (which both establish a
new block formatting context), and a float inside a flexbox would have to be
wrapped inside a flex item (which establishes a new block formatting context)).

Distinguish between row (fragmentainer group) height and column (fragmentainer) height.
TLDR; The spec [1] says that a fragmentainer height must always be 1px or
greater, to ensure progress. If we just do this, we'll avoid a lot of trouble
with limitations in the data types that we use.

While *column* heights will now be clamped to >= 1px, we still allow the height
of a *row* (fragmentainer group) to be less than 1px. We don't want the row to
take up more space than it should in its container.
E.g. <div style="columns:2; height:0.5px;"><div style="height:1px";></div></div>
will give a row height of 0.5px, as specified. The column height, on the other
hand, should be clamped up to 1px.

And here, for the nastiness that this CL aims to fix:
<div style="columns:2; height:0.25px;">
    <div style="height:10000000px;"></div>
</div>
The content to fragment is 10 million pixels tall, and the column height has
been specified as 0.25px. Internally in our code, heights are stored as
LayoutUnit, which is a fixed-point unit with 6 bits reserved for decimals. On
the other side of the decimal point we have room for 32-6 bits = 26 bits, which
is what we have for a signed integer. That's 25 bits for the absolute value.
That's just over 30 million. LayoutUnit uses saturated arithmetic so there'll
never be any integer overflow or underflow, but there may be other ill effects.
Like in this case, if we actually allow a column height of less than 1px (i.e.
0.25px), when the engine for example wants to figure out the *actual* column
count (column count was *specified* as 2, but there's no way we're going to be
able to fit a 10 millions pixels tall thing in two columns when the column
height is 0.25px, so the actual count will be way higher), we take the flow
thread portion (10000000px) and divide by the column height (0.25px). If we
divide something by something (positive) less than 1, we of course end up with
a quotient larger than the dividend. While the dividend may be small enough to
fit unclamped in a LayoutUnit (10000000px fits just fine), the quotient
(40000000) may not. So, while the actual column count really is 40 million (if
we allow columns to be shorter than 1px), the engine will clamp the 40 million
to fit inside a LayoutUnit. That's 33554431. This is the root of the problem,
and this incorrect column count value may in turn lead to other bad things,
even negative column heights in subsequent rows (and good luck calculating a
used column count off that!). It would probably be possible to cope with this,
if we only take extra care everywhere, when dealing with close-to-insane
numbers.

Or we can just do what the spec says, and clamp column heights to >= 1px.

Rebuild layout tree in flat tree order.
Marking the DOM for layout tree rebuild and the actual rebuilding is
now contained in the lifecycle update at a point where the shadow dom
distribution is up-to-date. We can therefore safely mark the flat-tree
ancestor chain without risking that it's broken by a distribution.

The point of doing RebuildLayoutTree in flat tree order is that layout
boxes can then be re-attached in the layout tree order which makes it
simpler to handle whitespace reattachment. For shadow trees and slotted
elements, when using the shadow-including tree order, we could have
elements rebuild their layout boxes in an order arbitrarily decided by
the slot assignments and slot positions in the shadow tree.

Note that while the RebuildLayoutTree traversal used to happen in the
shadow-including order, the layout attachment already happens in the
flat tree order.

See [1] for a plan to fix correctness and performance of whitespace
re-attachment.

This CL is doing the following changes:

1. Modify MarkAncestorsWithChildNeedsReattachLayoutTree to mark flat
   tree ancestry.

2. Rebuild distributed children for InsertionPoint and HTMLSlotElement.
   These children were rebuilt after their host's shadow tree before
   this change.

3. Factored out RebuildLayoutTreeForChild() as common code for both
   walking light tree children in ContainerNode, and distributed
   children in InsertionPoint and HTMLSlotElement.

4. Made FinalDestinationSlot() a member of node instead of a static
   function as it is now needed in multiple files.

This change also fixes breaking inside border-spacing adjacent to table

breaking inside border spacing, just because it's adjacent to such table
rows, but it looks like this was the behavior we got, by accident.

Stop matching scrollbar pseudo element without a scrollbar.
While matching rules for elements, we mark elements as affected-by-* for
user action pseudo classes like hover. It means that when the element is
later hovered, we need to recalculate style to apply hover styles to
that element.

In general, we currently don't support pseudo classes after pseudo
elements, but for scrollbar pseudo elements we do:

  ::-webkit-scrollbar:hover {}

However, we do not want such rules to mark the element as affected-by-
hover. The hover style on scrollbar parts get their hover style updated
when hovered regardless of any flags, and making scrollbar pseudo
element rules affect hover updates on the actual elements causes
unnecessary style recalcs.

More targeted resource-switching mechanism for SVG selection painting
The mechanism by which resources are generated for painting using
selection style for SVG text is a bit too heavy-handed, and can end up
invalidating both layout and other things. All that is needed is looking
up any <paint> ('fill' or 'stroke') references and invalidating any
state from the non-selection style.

Use a reduced/tailored version of SVGResourcesCache::ClientStyleChanged
that only recreates/swaps the SVGResources object for the LayoutObject
and wrap that mechanism in a scope object.

Collect media query results for non-matching stylesheets.
Viewport and device dependent media query results are collected after
an active stylesheet update happen. The results are collected on the

necessary that the active stylesheet update causes these media query
results to be up-to-date so that e.g. a viewport resize checks these
results to detect that we need an active stylesheet update for a given
resize.

That did not happen when we only added sheets for which the media
attrbute did not match, because adding a sheet with a null RuleSet does
not affect the computed style and the changed_rule_sets set was empty.

Now, if we add or remove a sheet which does not apply, and that sheet

kActiveSheetsAppended or kActiveSheetsChanged to trigger the re-
collection of those media query results.

Do not send redundant selectionchange-events (decouple focus)
This CL aims to remove redundant selectionchange-events
that were sent upon change of focus caused by element.focus(),
tab-navigation, spatnav and mouse-clicks.

Goals:
1. Send == one selectionchange-event, not two, for each caret jump.
2. Send <= one selectionchange-event, not two, for each focus jump.

Background:
When you click/tab to an <input> text-field, a
ViewHostMsg_TextInputStateChanged-message is sent to browser-side.

Problem:
With current logic, RenderFrameImpl::didChangeSelection is
called twice so two ViewHostMsg_TextInputStateChanged-messages
are sent to browser-side:
 (1) when focus leaves an <input>-field (unnecessary!).
 (2) when focus enters another <input>-field.

Worse, also the web page gets two selectionchange events.
The first one is immediately invalid so the webpage should
not react to it.

(1) happens because FocusController::setFocusedElement()
always clears the selection when a new element gets focus.

Solution:
Do not clear selection when focus moves. To keep current visual
behavior when focus moves away from a text-field we need to hide
that field's selection (clicking outside a text-field hides its
selection).

Test updates:
1. Check for one selectionchange event, not two.
2. LayoutTests' trees now expect the "hidden" selection.
3. A new test in WebFrameTest.cpp tests tab-key navigation.

Text track needs to derive the default font for the cues from the size

To avoid mutating style during layout, hook up a ResizeObserver from

logic to iterate on the style and layout.

This eliminates the need to have a special LayoutObject for
TextTrackContainer, so just use a LayoutBlockFlow and remove all traces
of LayoutTextTrackContainer.

symbols and functions in core/editing. This patch renames, moves
and unifies them.

There is a global MatchResult in css/SelectorChecker.h and if that one
is included anywhere in editing, then it will collide with a local
MatchResult used in iterators. Renaming the local one MatchResultICU
will both match the name of other symbols and avoid the collision.

Rename duplicate symbols inside core/dom

code that used the same symbol name for multiple purposes. This
renames those which also will make the life for symbol debugging
slightly easier.

kSupplementName: Name used in both CSSSelectorWatch.cpp and
DocumentParserTiming.cpp.

WTF::Unicode symbols: Depending on how unity builds are created,
global "using" statements can affect more than intended and trigger
warnings and errors. Now global "using" statements are not allowed by
the Chromium coding standard so assuming it will eventually apply to
Blink as well, the using statements might as well be removed now.

previousAncestorSiblingPostOrder was a function in both
FlatTreeTraversal.cpp and NodeTraversal.cpp. Could easily be made
class local and the name collision was no more.

Pass nextTextSibling to ::before layout rebuild.
Correct whitespace re-attachment relies on the next text node being
tracked in order to re-attach when a previous sibling element changes
display type. We did that just while traversing light tree siblings or
slotted siblings.

::before pseudo element display type may affect following whitespace
text node, so we need to pass on the next text sibling result from the
descendant traversal.

As we traverse siblings from right-to-left, we should also rebuild
::after before DOM siblings, and ::before after DOM siblings.

This fixes the case where an element, whose left-most child, or shadow
root child, is a whitespace text node, changes its ::before element's
display type from block to inline.

The pseudo element layout tree rebuild is renamed from reattach* to
rebuild* to match the semantics of the rest of the methods.

Corrected specificity for :not for default @namespace.
The argument to :not() consists of a universal, type, or a simple
selector. However, we prepend an implicit universal selector with the
default namespace URI to all compound selectors to correctly match only
elements in the default namespace. That is not necessary for compounds
inside pseudo argument lists, but we do in those cases as well.

When calculating the specificity for :not(), we assume its argument
consists of a single simple selectors, but in the case where we have a
default namespace, a namespaced universal selector is prepended. We
only added the specificity for the universal selector in that case.
Instead, walk all sub-selectors of the :not() compound when calculating
the specificity.

Reland: Do not send redundant selectionchange-events (decouple focus)
Reason for reland:
Update Win7/10 LayoutTests correctly: crbug.com/706119

Background:
Blink tells browser-side when a new <input>-element gets focus.
The information is passed in the
ViewHostMsg_TextInputStateChanged-message.

Problem:
With current logic, RenderFrameImpl::didChangeSelection is
called twice so two ViewHostMsg_TextInputStateChanged-messages
are sent to browser-side:
 (1) when focus leaves an <input>-field (unnecessary!).
 (2) when focus enters another <input>-field.

Worse, also the web page gets two selectionchange events.
The first one is immediately invalid so the webpage should
not react to it.

(1) happens because FocusController::setFocusedElement()
always clears the selection when a new element gets focus.

Solution:
When JavaScript moves focus to an element, element.focus(),
and when the user moves focus using tab-key navigation or
mouse, we don't clear the old selection (we hide it). This
means, we only send one selectionchange event, not two, for
each caret jump (as in Firefox).

Test updates:
1. Check for one selectionchange event, not two.
2. LayoutTests' trees now expect the "hidden" selection.
3. A new test in WebFrameTest.cpp tests tab-key navigation.

Follow-up will remove the remaining redundant clears:
crbug.com/692898 (tab jumps to non-editable elements).

No default value for AncestorSearchConstraint in locateFlowThreadContainingBlockOf().
The default used to be to bail out and return nullptr if it encountered
something unbreakable. It's better to let callers make a conscious choice here.
Tree-read operations (painting or hit testing, for instance) that call
LayoutObject::locateFlowThreadContainingBlock() are typically interested in
converting from flow thread coordinates to visual coordinates.

This is a defensive CL that only reverts unintended and bad changes from
https://codereview.chromium.org/2748973002 - added a TODO for cases where we
have LayoutState; if we are inside of layout, we should ideally stop at
strictly unbreakable ancestors.

The setNeedsReattachLayoutTree calls which were done outside of
updateStyle were all accompanied by a NeedsReattachStyleChange for the

Inside multicol we used to clip against the column box of each fragment. Since

Correctly track cross-thread pending FetchEvents.
ServiceWorkerGlobalScopeProxy is an object that resides on the
main thread heap, but is passed to the embedder and called
on the (service) worker thread. As the object is GC managed
by the main thread, the worker thread cannot update the proxy
object with references to heap objects residing in its heap,
as the per-thread heap design assumes that each heap only keeps
local heap references (via Member<T> and similar.) References
across heaps must instead be kept and handled by explicit
CrossThreadPersistent<> references.

This per-thread heap rule was not being followed for the tracking
of pending FetchEvents; adjust the map representation to do so.

Inherit 'viewBox' into view spec if it is valid
When constructing a view spec from a fragment identifier, the
(negated) hasEmptyViewBox() condition was used to determine if the
viewBox value should be set from the element. This condition however
will equate to:

  !(is-valid && is-empty) => !is-valid || !is-empty

meaning that invalid viewBox values would be transferred. In the case
where a <view> element without a 'viewBox' specified was referenced, the
'viewBox' value from the root could be overwritten by an invalid one.

Use only the validity of the 'viewBox' to determine if the value should
be inherited.

Consistent pagination strut propagation policies.
There's no break opportunity between a spanner and the next block in a column.
Also no break opportunity between a float and an in-flow block. The spec is a
bit vague here, but our implementation certainly doesn't support it.

We have to prevent strut propagation in such cases. If the first piece of
content inside the block (e.g. a line) doesn't fit inside the current
fragmentainer, it's the line that needs to be pushed, not the block.

Push the top margin of floats past all useless fragmentainers.
The top margin of a float is not to be split across fragmentainer boundaries if
it can be avoided. We had code to push the margin over to the next
fragmentainer if we were out of space, but we may actually have to push it all
the way to the next fragmentainer *group* (i.e column row) in some cases.

calculatePaginationStrutToFitContent() helps us get there. That's the method we
use to push oversize content (lines and unbreakable blocks) to a better place,
so let's use it for margins too.

Additionally, do not do an extra divide-by-1000 when the used helper

Accurate transfer of SerializedScriptValue allocation costs.
r456009 added transferring of allocation costs for a
SerializedScriptValue and any array buffers that it refers to,
transferring that cost from one v8 context to another as part
of a postMessage()

The handoff 'protocol' provided there fell short in that it could
fail to subtract transferable (array buffer contents) costs in
the source context, or end up doing it twice if the postMessage()
failed. Bookkeeping confusion resulted.

Rework the mechanism by instead having ArrayBufferContents keep
track of its external allocation cost registration status, so as
to prevent double discounting. Along with that, it is both safe
and accurate to unregister all allocation costs prior to
transfer. Should the value successfully be posted to its target
context, cost will be registered there. And if not, the value will
be destructed (..but without discounting allocation cost yet again.)

postMessage(): transfer allocation costs along with value.
A MessageEvent's data value will in some cases hold on to significant
amounts of off-heap memory, so we take care of registering that
external allocation with v8, so that it can be taken into consideration
by the GC triggering logic.

However, when posting a message to another context, we must arrange for
its total 'external allocation' to be associated with the target context.
Including the sizes of any transferables (array buffers), so balance the

Text control elements should contain all (shadow DOM) children.
For instance, INPUT type="search" elements allow styling of the cancel button,
via a ::-webkit-search-cancel-button pseudo element selector. We don't want authors
to be able to escape the containing INPUT element by styling the cancel button as
position:absolute, etc.

Force INPUT and other text control elements to be in the containing block chain of
all its descendants. This should be a good idea in general (and at least harmless),
and there's also C++ code [1] that essentially assumes that it is so.

Since this change makes canContainFixedPositionObjects() in LayoutObject and
ComputedStyle even more different than they used to be, we need to change some
code from using the one in ComputedStyle to the one in LayoutObject.

Two existing tests in fast/forms/ had to be updated, since they were adding together
offsetLeft of an INPUT element and offsetLeft of something inside the INPUT element
in a way that used to work by accident. Use getBoundingClientRect() instead, since
the test ultimately wants absolute coordinates anyway.

Improve handling of duplicate id's for SVG resources
This CL attempts to fix the known issues with duplicate id's and SVG
resources. There are a variety of cases where this fails, and the added
tests attempt to cover those as well as possible.

The know bugs generally stem from:

 * Resources being registered in (layout) tree order after style
   recalc. This for instance mean that any later defined resources
   will shadow any earlier appearing resource (which would the correct
   one.)

 * Removing a resource container does not consider that there could now
   be another resource that is no longer shadowed by the one removed.
   Together with the above, this also meant that removing a resource
   from the DOM could invalidate, and break, all occurences of said
   resource.

This CL attempts to handle the above by factoring the result of
getElementById into the equation, considering it to be "the truth" when
possible/required. The new methods registerResource and
unregisterResource form the basis of this, codifying the two basic
operations on which the tracking is built. The tracking of the
'registered' flag from LayoutSVGResourceContainer is now handled by
SVGTreeScopeResources. While this flag could be considered an
optimization at this point, DCHECKs are added to attempt to keep it
true to it's purpose.

Bit-mask incorrectly removed first-line pseudo bit.
The m_pseudoBits member only contains the 8 bits for the public pseudo
element bits, yet we used a mask to retrieve them. That mask was
incorrectly set to 0x1fe when it should have been 0xff. Anyway, that
mask is unnecessary and removed.

The mask issue caused StylePropagationDiff, returned from
diffPseudoStyles, to be NoChange for pure ::first-line changes. That
NoChange return were the only case which triggered first-line
invalidation properly.

Instead, always check for pseudo style changes in
pseudoStyleCacheIsInvalid. This fixes issue 698451.

should be put on LayoutObject and called as part of setStyle instead.

Call getUncachedPseudoStyle on correct node for ::selection.
getUncachedSelectionStyle is typically called for the LayoutObject we
are currently painting. This might not be the node the ::selection
style is matched for. Specifically, we request getUncachedSelectionStyle
on LayoutText objects, but we need to match the ::selection style on its
parent element.

This already happened inside getUncachedPseudoStyle, but it's guarded by
a hasPseudoStyle() call for the pseudo element type. In the case where
we pass in a LayoutText, we are relying on the computed style with the
PseudoIdSelection bit set to be propagated down to the LayoutText object.
That does not happen if the style change for the element parent is
NoChange or NoInherit.

Instead find the element for which we are matching ::selection in
getUncachedSelectionStyle instead. The firstAncestorOrSelf() call is
still present in getUncachedPseudoStyle as there may be other pseudo
elements types where we rely on this.

Remove out-of-date comment about scoped style resolvers.
Collecting features is not longer connected to StyleResolver and the
comment is no longer correct in any way. The nullptr test is still
there because a TreeScope may have stylesheet candidates which do not
have style sheets. A candidate is causing the TreeScope to be added to
the active list, while it has to have at least one active stylesheet to
enforce a ScopedStyleResolver instance.

Allow flow thread portion logical bottom to be above its logical top.
We used to try to prevent this, as an attempt to make sure that no
fragmentainer group would have overlapping flow thread portion rectangles with
other fragmentainer groups. But that was already easily achievable with e.g. an
empty block between two column spanners anyway.

There is a legitimate reason for the flow thread portion bottom to be above the
top: negative margins.

Introduce MultiColumnFragmentainerGroup::logicalHeightInFlowThreadAt().
Less duplicated code. Some extra care is now needed, to make sure that we don't
end up with negative logical heights.

Avoid negative content box sizes.
Negative values had two possible causes:

1. Subtracting the scrollbar size from the border box size. Scrollbars do not
affect the border box size, but they occupy space between some border edge and
padding edge. This means that the presence of a scrollbar on an object reduces
the size of the content box and the containing block established by said
object. This means that if e.g. the specified width of an object is 10px and it
has a vertical scrollbar that takes up more than that, e.g. 15px, the content
box width should become 0, not -5px.

2. Subtracting two huge (or even saturated) LayoutUnit values from one
LayoutUnit value. When we during layout convert a specified content-box width
to border-box (via padding-box), which is what LayoutBox::m_frameRect uses, we
may end up with saturated LayoutUnit values, so that:
LayoutUnit specified_content_box_width = <whatever, something nice, maybe>;
LayoutUnit left_padding = LayoutUnit::max() /*(or something huge, at least)*/;
LayoutUnit right_padding = LayoutUnit::max() /*(or something huge, at least);*/
LayoutUnit padding_box_width = content_box_width + left_padding + right_padding;
LayoutUnit content_box_width = padding_box_width - left_padding - right_padding;
Here, content_box_width won't be the same as specified_content_box_width,
because padding_box_width got saturated. That's kind of inevitable, with
saturated arithmetic and all, but what's worse is that we used to end up with a
negative value in content_box_width, which is illegal. So just clamp negative
values to 0 to avoid that.

Negative box sizes have various kinds of ill effects, such as inline-axis
misalignment and unwanted negative block direction progression. It was possible
to get negative padding (which is illegal) resolved from percentage values.
This in turn caused unnecessary assertion failures in multicol.

Attempted to come up with sensible layout tests that don't make assumptions
about how the engine deals with extreme values internally.

Compute a more correct "screen scope" transform for SVGSVGElement
For getScreenCTM, only the position (translation) of the outermost svg

rather than just the position of the layout box. Since using this method
works for any (attached) element, implement getScreenCTM without using
computeCTM, and get rid of the ScreenScope variant of the latter. This
also allows us to simplify SVGSVGElement::localCoordinateSpaceTransform
a bit, and drop the CTMScope argument from the
localCoordinateSpaceTransform declaration(s).

It's not clear from [1] how elements which are not in the rendering tree
(i.e has 'display: none' or similar) should be handled. With this
implementation we will return an identity matrix in those cases, which
doesn't seem unreasonable. (The option would be to return 'null', which
is how elements not in the document should be treated, but we don't have

Invalidate custom pseudo elements for RuleSet invalidations.

elements inside the UA shadow, and no id, class, or attribute selectors

We utilize the same invalidation set as for type invalidations and mark

This means we will traverse into all shadow sub-trees, but it should at

Schedule a type selector invalidation set for RuleSet invalidations.
We marked all elements which had a selector in the tagRules bucket for
style recalc for RuleSet invalidations. That means we would recalculate
style for all spans if we added a stylesheet containing a rule with an
"#id span" selector (but not for "#id span.class" as that ends up in
the classRules bucket).

Instead, use an invalidation set containing only tag names for the
selectors where there are no ids, classes, or attribute selectors, and
which have a type selector in the rightmost compound. This means that
"#id span" will not add "span" to that set, but "span" and "div span"
will. "div span" will not add "div", and "div *" will cause a full
scope recalc. In order to support invalidation for those, we would have
had to have one invalidation set for each tag name instead of a single
descendant invalidation set for all.

RuleSet invalidations schedule this typeRuleInvalidationSet on the root
of the TreeScope When doing ruleset invalidations.

Avoid over-eager clipping of child layers in multicol.
Self-painting layers (caused by e.g. position:relative) don't contribute to
visual overflow in their parent layout object; see
LayoutBox::addOverflowFromChild(). We cannot use the visual overflow rectangle
set on the flow thread when calculating the bounding box of a fragment
established by a child layer.

Therefore, only clip in the flow thread's block direction in
overflowRectForFlowThreadPortion(), and leave the inline axis alone. I
simplified the implementation, since it's now way easier to start with an
infinite rectangle, and just limit the dimensions that need it afterwards.

Also got rid of an old check for hasOverflowClip(), which must have been
residue from the CSS regions implementation.

This also happened to fix some inaccuracies mostly invisible to the naked
eye, when it comes to transform:scale()d text with glyphs that have negative
left bearing or overflow the line box vertically. It looks like we measure and
lay out with the CSS computed font, and then switch to a scaled font when
painting, so that it looks crisp and nice. This may result in tiny
inaccuracies in the bounding box of the text, and
fast/borders/border-antialiasing.html exhibited this, and had to be
rebaselined. Added fast/multicol/scale-transform-text.html to better
demonstrate what we're fixing.

paint/invalidation/multicol-with-relpos.html also had to be rebaselined,

Add type selector invalidation set for ruleset invalidations.
We currently look at RuleSet::tagRules() to figure out if an element
needs a style recalc when adding a stylesheet. This recalculates too
much for rules like "#id span" which ends up in the tagRules bucket,
causing style recalcs for every span. The plan is to use an
m_typeRuleInvalidationSet which contains the tag names for rules which
don't contain other simple selectors which have associated invalidation
sets.

For instance, "#id span" will not add span to m_typeRuleInvalidationSet
since we can rely on the invalidation set for #id to invalidate spans.
However, "span" or "div span" will add span to that set.

This CL prepares for this by introducing the set and a way to collect
it. This new set will be scheduled on the root node of the TreeScope
when adding/removing a stylesheet. We did not support scheduling
invalidation sets on the document node, so this CL adds that
possibility as well.

The color picker is a separate window, and the contents of the window is
generated in ColorChooserPopupUIController.cpp.  colorSuggestionPicker.js
resizes the window to exactly fit the content, but the zoom factor is applied
afterwards, causing an additional reflow (see WebPagePopupImpl.cpp:329).
There is no guarantee that the zoomed contents will fit the window any more,
and much of the time it doesn't.

By setting zoom factor before forcing layout, the final size is reached the first
time around, and the window size should be correct.

Support subpixel layout of borders.
This cl implements subpixel layout of borders.  Painting of subpixel
borders now uses rounding to nearest CSS pixel, and is aligned with
Edge.  Handling of device pixel ratios > 1 isn't implemented here,
and is better covered in a separate task.

This does not implement subpixel borders for tables, as that interacts
with table layout width calculations, which would also need to be
adapted to subpixels.  Again, that's better dealt with in a separate
task.

A number of test cases had to be rebaselined, due to minor changes in
layout and/or painting.  Most of these changes appear in tests that uses
zooming, and implicitly have fractional borders.

svg/zoom/page/zoom-replaced-intrinsic-ratio-001.htm now looks a bit
broken, but that's due to an unrelated issue with aspect ratio and
subpixels (in LayoutPart, if I recall correctly).

Devirtualize Visitor and remove inline visitor specialization.
The Blink GC infrastructure requires its managed objects to provide
a "trace()" method which will visit all the heap references it keeps
into the Blink GC heap, by calling the "trace()" method on each of
these via an incoming |visitor| argument (a Visitor.)

The Visitor interface is really only used for that, i.e., to perform GC
marking, so the flexibility it provides by way of overridable virtual
methods, is unused. And it slows down the GC marking phase, something
the specialized "inline visitor" (InlineGlobalMarkingVisitor) demonstrated,
which devirtualized the mark() method, with noticable improvements to
overall GC marking times.

Given that and Visitor's use, devirtualize Visitor entirely and make
it a GC marking visitor and nothing else. Besides removing code complexity,
this also allows the removal of InlineGlobalMarkingVisitor along with
all the specialized trace() implementation methods that we emit for each
Blink GC managed object.

Performance numbers show a ~10% improvement on marking times for
oilpan_gc_times.{tough_animation_cases, blink_perf_stress}; code size
(Android(ARM) official build, content shell) is 180k less.

Merge list of orthogonal writing mode roots into depth-ordered layout list.
If we're going to perform a series of subtree layouts, rather than one layout
from LayoutView, and we at the same time have a list of orthogonal writing mode
roots that need to be laid out before their ancestors, we need to make sure
that subtrees are laid out in an overall tree depth ordered manner, or we risk
skipping layout of a subtree needing layout. That would cause trouble for the
column balancer (which examines the tree after layout and expects everything to
be laid out), and quite possibly other kinds of trouble elsewhere too.

SVG objects with same idrefs conflict when under different shadow root
When SVG idrefs are the same, even though the
LayoutSVGResourcesContainers are created under different shadow roots,
they conflict and only the last one is available. The problem is that,
currently, the HashMap mapping id's to LayoutSVGResourcesContainers are
owned/scoped to the document instead of the treeScope.
This CL moves that hash map from document to treeScope, so that
LayoutSVGResourcesContainers with the same id in different shadow roots
won't conflict.

Currently the following 2 maps (which are wrapped into the
SVGDocumentExtensions class) are owned by document instead of treeScope:

  HashMap<AtomicString, LayoutSVGResourceContainer*> m_resources;
  HeapHashMap<AtomicString, Member<SVGPendingElements>> m_pendingResources;

Thus when a new LayoutSVGResourcesContainer with the same id is created,
it is inserted into m_resources and overwrites the one with the same
key (id).

This CL separates these 2 maps from SVGDocumentExtensions and wrap them
into a new class (named SVGTreeScopeResources), and lets TreeScope have
them as a member variable (m_svgTreeScopedResources).
This CL also moves the corresponding methods accessing these 2 maps into
the new class.

To make this work together with <use>, we need to make sure to use the
TreeScope of the "original" element. Move the helper from LayoutSVGTextPath
to SVGElement::treeScopeForIdResolution and then use that for this.

Stop requiring a reader in MultibufferDataSource::SetBitrateTask()
Callers of MultibufferDataSource::SetBitrate() must not be required to
be aware of whether or not there is a |reader_| available, because
that's internal MultibufferDataSource state that changes for several
reasons, some of which aren't necessarily visible to the client calling
SetBitrate(), e.g., OnBufferingHaveEnough().

We can now lay out block-level floats and in-flow blocks inside a multicol

We typically have no business inside a zero-height column set, since
fragmentation is impossible there. Fragmentation requires a positive
fragmentainer block size to ensure content progression. So keep looking for a
column set that has a height, and use that one instead, as long as its flow
thread start offset is the same as the one we were requested to map to a

Add use_rtti gn arg to enable rtti globally in the build
Some sanitizer configs already enabled rtti, move the logic to the arg
default value to make experimenting easier. Can be useful when dealing
with some asan-instrumented build startup issued that may go away when
rtti is enabled globally, but don't fall into the existing enable-rtti
cases.

One example scenario I had was with a shared_library built with both rtti
and exceptions (in a downstream project) causing immediate asan failure
on startup around std::exception typeinfo alignment. Rebuilding with
rtti enabled globally made things work, so it helps if that's possible
with just a gn arg.

Note that targets that need rtti to be not disabled regardless of global
settings (e.g. third party libraries like icu that need rtti to build)
can still remove the //build/config/compiler:no_rtti config and add
//build/config/compiler:rtti in its place; this is unchanged.

Need to clear viewport dependent units when switching print mode.
Switching between print and screen changes the size of the initial
containing block. Viewport dependent lengths need to be recalculated
and the cache for matched properties cleared.

Normally, notifyResizeForViewportUnits() is called from
performPreLayoutTasks when the initial containing block size changes.
That does not happen when laying out for printing and going back to
screen layout. We skip setting m_lastLayoutSize in
sendResizeEventIfNeeded. We probably do that to avoid triggering resize
events going back and forth between the print (preview) size.

Make sure we clear the matched properties cache from StyleResolver when

Use ShadowData in DropShadowFilterOperation
This replaces the "open-coded" (and somewhat compacted) version of a
ShadowData structure within DropShadowFilterOperation with an actual
ShadowData. While this makes the structure slightly larger, it allows
for some additional code-reuse - mostly around style resolution. It's
also a first step against more correct handling of the 'currentcolor'
value within the drop-shadow(...) filter function.
There's a slight change in behavior since ShadowData stores the relevant
values as 'float' rather than as 'int' like the "open-coded" version.

We shouldn't have to do this if the class type has been fully

into this (as the expression will clearly have to be evaluated at
compile-time), but gtest usage of traits may end up evaluating their
predicate expressions in compiled code, thus requiring that the trait

Reschedule sibling invalidations as descendant on removal.
When removing elements we schedule sibling invalidations based on
element attributes and state as descendant invalidations when
necessary. However, that didn't work correctly if we removed an
attribute and then removed the element before the sibling invalidation
for the attribute was effectuated.

For instance, if you remove a class affecting succeeding siblings
through selectors, we schedule an invalidation set for that change, but
it will be cleared right after if we remove the element (see the added
test).

Instead we reschedule sibling invalidations on the parent node before
the invalidations for the removed element are cleared.

Disallow heap objects containing unsafe on-heap iterators.
Do not allow BlinkGC managed objects to include unsafe iterators of

Reland: Collect active stylesheets and and apply asynchronously.
This CL enables asynchronously updating the lists of active stylesheets
applying any style changes using rule set invalidations. This means we
more often avoid full style recalcs when we add or remove stylesheets
from the document as well as when the evaluation of media queries
change.

In general, we now alway compare new and old stylesheets by comparing
their rulesets and schedule style invalidations for removed and added
rulesets.

When media queries changes, we used to give completely in and
recalculate all style once we discovered a media query changed its
evaluation. With this patch, we clear rule sets for sheets which
contain media queries which means we will invalidate rules for the sets
before and after the query change. This can be further refined by only
clearing rule sets when the sheets has a media query which actually did
change evaluation, and also just schedule invalidations for rules which
are inside @media rules.

TreeScopeStyleSheetCollectionTest.cpp is removed as it is replaced by
ActiveStyleSheetsTest.cpp which landed earlier.

updateActiveStyle() has been added a few places where
ensureStyleResolver() previously caused active stylesheets to be up-to-
date. ensureStyleResolver() is now merely a method which creates the
StyleResolver if necessary and returns it.

There are some cleanups and code removal which needs to be done after
this CL, but I have left those out to make this CL as small as
possible. For instance resolverChanged(), which synchronously updated
the active stylesheets, has an empty implementation instead of
including a lot of removals in this CL. The code for lazy-appending
stylesheets in StyleResolver is still there, but not in use.

Merge setTimeout calls with same timeout for webfont tests.
Landing async stylesheet update caused a regression in font-display
tests. The values "fallback" and "optional" block display for 100ms
according to the spec. The tests had a setTimeout call to trigger font
loading and a setTimeout call to trigger notifyDone() to render before
100ms has passed with the same timeout value. However, the timer for
allowing fallback display triggers before the notifyDone triggers in
Debug builds on Mac. Calling notifyDone from the same setTimeout
callback as triggering font loading.

The intention of the test is to trigger the screen dump when 0s has
passed, so this should be OK. I have not identified what exactly changed
with the async stylesheet patch and why the timeout methods are
interleaved with the timeout for enabling fallback rendering.

Removing one of the other tests or one of the font-display values from
the test array also makes the "fallback" and "optional" start passing
without this change, so there is clearly a timing issue here.

ActiveScriptWrappable: GC wrappers in detached ExecutionContexts.
Blink objects that implement (Active)ScriptWrappable have the ability
to keep their corresponding v8 wrapper object alive across GCs by
overriding and implementing ScriptWrappable::hasPendingActivity().

Once an ExecutionContext has become detached, we no longer want to
retain wrappers belonging to it, as that will lead to memory leaks.
With full bi-directional tracing of references across the v8 and Blink
heaps, it is possible to make the lifetime of objects "more accurate",
but not keeping a wrapper alive once in a detached setting, has proven
to work out well in practice.

Consequently, a ScriptWrappable in a detached ExecutionContext should
not be retained, even if hasPendingActivity() return |true|. That is,
we should simply ignore hasPendingActivity()'s result, freeing the
implementations of it from having to take care of this 'detached'
detail.

This behavior is already provided by the 'standard' Blink wrapper
visitors that v8 invokes during GC, but not with wrapper tracing,
which is what this CL brings.

It does so by extending ActiveScriptWrappable with a predicate for
checking if the object's ExecutionContext has signalled destruction.

(The natural(?) way to express that is to parameterize ActiveScriptWrappable<>
over the class that implements the interface. This makes for a CL
with a larger footprint.)

The DOMTimer's ScheduledAction hold on to the script source and
state needed to execute the timer action. Let go of ShceduledAction's
resource early.

Apart from reducing the lifetime of script source, this is a speculative
fix for crashes reported in v8::PersistentValueVector::Clear() during
lazy sweeping of ScheduledAction objects.

Only the first layout pass needs to go deep when pagination state changes.
Since we now re-use the LayoutState object in multipass layout (caused by
either fragmentation or the PaintLayerScrollableArea::FreezeScrollbarsScope
mechanism), we need to notify the LayoutState object when we have performed the
necessary deep layout pass, so that not all subsequent passes also go deep
needlessly.

PaymentApp: Implement the JNI bridge
Add two native methods to ServiceWorkerPaymentAppBridge, and implement
them in service_worker_payment_app_bridge.cc. The two methods are
GetAllAppManifests and InvokePaymentApp. At the moment, they are just
stubs, although GetAllAppManifest contains a bit of code, mainly
for illustration and to avoid compile errors for unused @CalledFromNative
methods in ServiceWorkerPaymentAppBridge.

Collect active stylesheets and and apply asynchronously.
This CL enables asynchronously updating the lists of active stylesheets
applying any style changes using rule set invalidations. This means we
more often avoid full style recalcs when we add or remove stylesheets
from the document as well as when the evaluation of media queries
change.

In general, we now alway compare new and old stylesheets by comparing
their rulesets and schedule style invalidations for removed and added
rulesets.

When media queries changes, we used to give completely in and
recalculate all style once we discovered a media query changed its
evaluation. With this patch, we clear rule sets for sheets which
contain media queries which means we will invalidate rules for the sets
before and after the query change. This can be further refined by only
clearing rule sets when the sheets has a media query which actually did
change evaluation, and also just schedule invalidations for rules which
are inside @media rules.

TreeScopeStyleSheetCollectionTest.cpp is removed as it is replaced by
ActiveStyleSheetsTest.cpp which landed earlier.

updateActiveStyle() has been added a few places where
ensureStyleResolver() previously caused active stylesheets to be up-to-
date. ensureStyleResolver() is now merely a method which creates the
StyleResolver if necessary and returns it.

There are some cleanups and code removal which needs to be done after
this CL, but I have left those out to make this CL as small as
possible. For instance resolverChanged(), which synchronously updated
the active stylesheets, has an empty implementation instead of
including a lot of removals in this CL. The code for lazy-appending
stylesheets in StyleResolver is still there, but not in use.

Simple BlinkGC heap compaction.
This implements heap compaction for the Blink GC infrastructure
(Oilpan), compacting the arenas of the BlinkGC heap which are most
susceptible to becoming fragmented during actual use.

Fragmentation is a real problem and a growing one while browsing anything
but static pages: the amount of unused, but allocated, memory is
fluctuating higher over time.

To avoid leaving increasing amounts of unused holes in our heaps,
heap compaction will periodically squeeze out the unused portions,
packing together the live objects. The heap pages that are then
left as unused, are subsequently released and returned to the OS.

Due to a fortunate property of Blink heap collection types, providing
such compaction is within relatively easy reach. Experiments show that
the arenas which hold such collection objects ("backing stores") are
the ones that develop fragmentation the most & persistently. While not
a complete heap compactor of all Blink GC arenas, it addresses the
fragmentation problem where it is most pressing. More can be done, later.

Use hash set instead of vector for changed RuleSets.
That way, we don't have to consider the same RuleSet multiple times for
invalidation on active stylesheet update. This fixes a regression in
PerformanceTests/CSS/StyleSheetInsert.html which would have been
introduced by https://codereview.chromium.org/2557533005

This works because the same style element source text used multiple
times will make us use the same StyleSheetContents from the cache and
hence the same RuleSet for all 50 sheets added in that test. It's a bit
like cheating, but this will also make sure we don't invalidate for the
same RuleSet twice if we re-order stylesheets by removing/inserting a
style element where the CSSStyleSheet pointer will be different, but
the RuleSet stays the same.

PaymentApp: Make the PaymentAppFactory asynchronous
The code for fetching and filtering payment instruments in
PaymentRequestImpl is asynchronous anyway, so this change is not too
intrusive. The main thing is to insert an extra asynchronous step to
populate the mApps list before payment instrument filtering starts.

If we want to take this further, a good next step would be to start
showing apps as they are discovered, instead of waiting until we have
received all the payment apps. It would also be a good thing to
refactor some of this functionality out of the PaymentRequestImpl, as
it is growing quite complex.

Other changes that went into this commit:

* Change the PaymentAppFactory into a singleton, rather than being a
  holder class for static functions.

* Extend the AdditionalPaymentFactory functionality, so that the
  PaymentAppFactory can have many additional factories. This lets us
  make the ServiceWorkerPaymentAppBridge an additional factory, and
  normalize the relationship between the two classes.

* Add two unit tests for testing delayed payment app creation.

Make sure media query results are re-collected.
When media attributes change on style elements, we need to re-append
all sheets in the scope in order to collect the viewport and device
dependent media results correctly. This already done forced by the
FullStyleUpdate in parseAttribute, but we want to minimize the changes
here with async style update and ruleset based invalidations by marking
the treeScope dirty, and if nothing changed, invalidate no style.

However, we need to re-add global rule data, or at least the media
query results.

Example: say that we have a window width of 800px below. After the
media attribute has been changed, we don't need to recalculate any
styles, but we need to make sure we detect style changes crossing the
width of 2000px instead of 1000px.

<style media="(min-width: 1000px)"> ... </style>

<script>
  styleElement.setAttribute("media", "(min-width: 2000px");

Pass the treeScope instead of a stylesheet pointer and remove the

This makes the setNeedsActiveStyleUpdate implementation like what we

Also, setNeedsActiveStyleUpdate calls are removed where we call
removeStyleSheetCandidateNode() since that method already marks the

Better isPageLogicalHeightKnown() implementation.
Need to consult the flow thread, if we have one. We may run into situations
where fragmentainer groups in the first column set have got their height
calculated, while later column sets still haven't calculated it [1]. So
checking if flow thread offset 0 is in a fragmentainer of known height isn't
good enough.

Also moved the implementation from LayoutBlock to LayoutBox, since it's pretty
coincidental that we currently don't need this particular method outside of
LayoutBlock.

[1] LayoutMultiColumnSet::recalculateColumnHeight() may reset the column
heights if it detects that the column set has been moved since previous layout
pass.

Never position a float after it has been placed.
When a float is marked as "placed" (which happens in
LayoutBlockFlow::placeNewFloats()), it means that it has been added to a float
interval tree. It is not allowed to move a float afterwards (unless we remove
and re-insert the floats somehow, e.g. by re-laying out its containing block).
Otherwise, the interval tree may get out of sync with reality, and we may fail
to find the reference to a FloatingObject in the interval tree when deleting a
FloatingObject, so that we end up deleting the FloatingObj
