Previously we depended on an associated document on the ESO to get to
the page, but Workers do not have documents. However, we can simply get
to the page with `principal_host_defined_page`, removing the issue.
Continues the work started in #5386 to simplify handling of positional
value list shorthand properties.
Previously we would parse these as `StyleValueList`s and then rely on
`StyleComputer::for_each_property_expanding_shorthands` to expand them
into longhands.
This required a bit of work to handle `ShorthandStyleValue`s for the
`@page` `margin` descriptor.
Previously we would instead parse these as single values and rely on
ad-hoc functionality in `for_each_property_expanding_shorthands` to
expand them to longhands.
This gets us a step closer to removing that ad-hoc functionality.
This also fixes a bug in the view transitions code that was
required to get the imported test to pass. The code for setting
the initial containing block size just did not set the right thing,
since doing so would trigger an error later on.
That later error resulted from walking up the tree, without
considering that the document element has a parent that is not
itself an element. (and then doing element things to it)
...when `LengthOrAutoOrCalculated` holds calculated value. We were
incorrectly assuming that if contained value is not auto, then it must
be a length.

The existing conversion was rounding to the nearest millisecond, which
is much less precision than most videos will want. Instead, use only
integer math to directly convert the presentation time to seconds and
nanoseconds for our AK::Duration to represent accurately.
Now follows the same pattern as PaintableBox and StackingContext, where
it exits if hidden, then hit tests children, then hit tests itself if
it's `visible_for_hit_testing()`.
This change removes premature reset of
`block_container_y_position_update_callback`. Also makes callback
private in `BlockMarginState`, because resetting it independently of
currently accumulated margins is incorrect.
Lots of test expectations are updated, but there is no visual
difference.
Fixes https://github.com/LadybirdBrowser/ladybird/issues/6074
Callback registered by
`register_block_container_y_position_update_callback()` is executed
after `layout_block_level_box()` returned, so capturing stack variable
`y` by reference is UB.
We also support interpolating from a CalculatedStyleValue to a
compatible dimension or percentage style value.
This also brings with it a couple of improvements in how we handle
interpolation between mixed dimension and percentage types in terms of:
- Proper simplification of the resulting calc()
- Improved handling of interpolation outside the 0-1 range
The HTTP cache is now stable enough that we can ask more people to help
us testing it. So let's turn it on by default! It can be turned off with
--disable-http-cache if needed.
...navigable shared attribute processing steps.
After e095bf3a5fhttps://wpt.live/html/rendering/pixel-length-attributes.html ends up in
this function with null navigable, which leads to crash while executing
steps. Adding early return in case iframe's document doesn't have a
navigable is enough to make the test pass again.
This commit doesn't import the WPT test, because it's already imported
and we have it disabled since it takes too much time on CI.
This behaviour should only apply to literal percentages as clarified
here: 4ee8429
We were also doing this wrong by converting the numeric type of the calc
to Length which was causing values to be defaulted to 1 instead (hence
the new passing tests for computed values as well)
This ensures that we clamp values for properties like padding-* to valid
ranges (non-negative in this case) if they are specified with `calc()`.
The length-related changes in this commit combined with the ones from
the previous commit fix the primary layout issue on https://lwn.net
(yes, not the first place I would have expected problems either).
According to ECMA-262 §15.4.5 (MethodDefinitionEvaluation),
getters and setters defined in class bodies
must create property descriptors with
[[Enumerable]]: false. Previously we incorrectly marked them enumerable.
This patch updates `ClassMethod::class_element_evaluation` so that both
getter and setter descriptors use `.enumerable = false`.
Previously, the hosts file was updated at the same time the WPT repo
was cloned, but updating the hosts file is only necessary for commands
that start the WPT test runner.
SIMD loads/stores checked bit 0x20 of the align immediate to detect a
following memory index, unlike scalar mem ops which use 0x40 per the
multi-memory encoding. This caused the memidx byte to be misparsed as
the next immediate (e.g. offset).
Update both SIMD sites (v128 load/store and lane variants) to check and
clear 0x40, then read LEB128<u32> memidx.
Repro:
(module (memory $m0 1) (memory $m1 1)
(func (export "go")
i32.const 0
v128.load (memory 1)
drop))
Before: printed memidx 0 with offset 1.
After: prints memidx 1 with offset 0.
The opcode entry declared i16x8_replace_lane with pushes = -1, but
replace_lane pops 2 (vector, lane value) and pushes 1 result vector.
Set pushes to 1 to match the other replace_lane opcodes.
Negate was incorrectly returning "== 0", a copy/paste from EqualsZero.
This patch corrects it to return "neg", matching the operator's actual
semantics and WebAssembly mnemonics (f32.neg, f64.neg).
Replaces spin until with GC-allocated counting object that invokes
destruction callback once all child navigable documents are destroyed.
The change doesn't have a test but not using spin until is strictly
better than using it. Also improves https://www.rottentomatoes.com/
where previously we would hang or crash after loading.
...selector. Grammar per spec: `::slotted( <compound-selector> )`, so
we should reject selector as invalid if first compound selector is
followed by something else.
This change makes layout more correct on https://www.rottentomatoes.com/
