I added this file thinking it was necessary for the wpt run command.
However, it's only needed for updating expectations metadata. Since wpt
run always regenerates MANIFEST.json before updating expectations, we
can safely delete this file from the repository.
Reordering these calls allow us to ensure that all encoders are able to
return the size of the image before they are requested to decode the
whole bitmap.
The Test262RunnerHandler class in test-test262 was made in order to
spawn a subprocess, connect to its input/output error pipes, and obtain
its return value.
Later on, a copy of this implementation was added to TestSed with
modifications, such as adding support for reading from the output pipes
as well.
Unify these two implementations into a new Core::Command class. This new
implementation is more closely modeled from the TestSed implementation
due to the extra functionality it implemented.
Once we've resolved the used flex item width & height, we should allow
percentage flex item sizes to resolve against them instead of forcing
flex items to always treat percentages as auto while doing intrinsic
sizing layout.
Regressed in 8dd489da61.
When specifying either `background-position-x: right` or
`background-position-y: bottom` without an offset value no
EdgeStyleValue was created.
However, the spec says the offset should be optional.
Now, if you do not provide an offset, it creates the EdgeStyleValue
with a default offset of 0 pixels.
We do this by piggybacking on FormattingContext helpers instead of
reinventing the wheel in FlexFormattingContext.
This fixes an issue where `min-width: fit-content` (and other
layout-dependent values) were treated as 0 on flex items.
This makes the cookie banners look okay on https://microsoft.com/ :^)
This is just a straight (and fairly inefficient) implementation of IPv6
parsing and serialization from the URL spec.
Note that we don't use AK::IPv6Address here because the URL spec
requires a specific serialization behavior.
If an inline-block has a percentage height that relies on the auto
height of the containing block, it should always resolve to the
automatic height of the box, regardless of the percentage value. This
change may seem confusing, but it aligns with the behavior of other
engines.
Unlike all other primitives elliptical arcs are non-trivial to
manipulate, it's tricky to correctly apply a Gfx::AffineTransform to
them. Prior to this change, Path::copy_transformed() was still
incorrectly applying transforms such as flips and skews to arcs.
This patch very closely approximates arcs with cubic beziers (I can not
visually spot any differences), which can then be easily and correctly
transformed in all cases.
Most of the maths here was taken from:
https://mortoray.com/rendering-an-svg-elliptical-arc-as-bezier-curves/
(which came from https://www.joecridge.me/content/pdf/bezier-arcs.pdf,
now a dead link).
This tests that we can successfully parse the "everything" TVG files,
which make use of every feature in TinyVG.
Test files taken from https://github.com/TinyVG/examples (MIT).
This test proves the ability of TransformStream to execute
caller supplied code in the flush callback, and have access to
TransformStreamDefaultController.
This test proves the ability of TransformStream to execute
caller supplied code in the start callback, and have access to
TransformStreamDefaultController.
This test proves the ability of TransformStream to execute to execute
caller supplied code in the transform callback that can transform
incoming chunks, and have access to TransformStreamDefaultController.
There are two parts to this fix:
- First, StyleProperties::transformations() would previously omit calc()
values entirely when returning the list of transformations. This was
very confusing to StackingContext which then tried to index into the
list based on faulty assumptions. Fix this by emitting calc values.
- Second, StackingContext::get_transformation_matrix() now always calls
resolve() on length-percentages. This takes care of actually resolving
calc() values. If no reference value for percentages is provided, we
default to 0px.
This stops LibWeb from asserting on websites with calc() in transform
values, such as https://qt.io/ :^)
This change implements following paragraph from placement algorithm in
the spec:
"If the largest column span among all the items without a definite
column position is larger than the width of the implicit grid, add
columns to the end of the implicit grid to accommodate that column
span."
There were places in the grid implementation code with copies of this
text, but those were completely unrelated to the code where they were
being pasted so I removed them.
There were two problems:
1. parse_compressed_object_with_index() parses indirect objects
without going through Parser::parse_indirect_value(), so
push_reference() / pop_reference() weren't called.
Manually call them, both for the indirect object containing
the object stream and for the indirect object within the
object stream.
2. The indirect object within the object stream got decrypted
twice: Once when the object stream data itself got decrypted,
and then incorrectly a second time when the object data within
the stream was read. To fix, disable encryption while parsing
object stream data (since it's already decrypted).
The test is from http://opf-labs.org/format-corpus/pdfCabinetOfHorrors/
which according to readme.md at the same location is CC0.
I created this by typing "sup" into TextEdit.app on macOS 13.4,
hitting Cmd-P to bring up the print dialog, clicked the PDF button
at the bottom, changed Title and Author to "sup", clicked
"Security Options…", and checked "Require password to open document"
(with password "sup").
This file tests several things:
- It has a compressed stream as first object. This used to make the
linearization dict detection logic assert.
- It uses AES as encryption key using version 4 of the encryption
dict. This used to not be implemented.
Max width shouldn't be tied to min width, commit d33b99d went too far
and made them the same when the table-root had a specified percentage
width.
Fixes#19940.
Since the underlying HTML::Window can change, caching property accesses
on WindowProxy is not as simple as remembering the shape. Let's disable
caching here for now. We can come back to it in the future when we have
no low-hanging fruit left. :^)

The previous iteration of this API was somewhat odd and rough in random
places, which degraded usability and made less than perfect sense.
This commit reworks the API to be a little closer to more
conventional promise APIs (a la javascript promises).
Also adds a test to ensure the class even works.
Make sure the insets and margins calculated according to the spec are
not later ignored and ad-hoc recomputed in
layout_absolutely_positioned_element.
Use the static position calculation in a couple of places where the
spec (and comment) was indicating it should be used.
Fixes#19362
The tests still pass, but opening the files in Ladybird and Safari or
Firefox shows clearly where the layouting in Ladybird is incorrect
for some absolute positioned elements. The previous 1px border was
subtly hiding some issues.
