This is not that easy to use for test developers, as forgetting to set
the url back to its original state after testing your specific API will
cause future navigations to fail in inexplicable ways.
This patch implements `Range::getClientRects` and
`Range::getBoundingClientRect`. Since the rects returned by invoking
getClientRects can be accessed without adding them to the Selection,
`ViewportPaintable::recompute_selection_states` has been updated to
accept a Range as a parameter, rather than acquiring it through the
Document's Selection.
With this change, the following tests now pass:
- wpt[css/cssom-view/range-bounding-client-rect-with-nested-text.html]
- wpt[css/cssom-view/DOMRectList.html]
Note: The test
"css/cssom-view/range-bounding-client-rect-with-display-contents.html"
still fails due to an issue with Element::getClientRects, which will
be addressed in a future commit.
Attributes have a max value length of 1024. So we theoretically need to
support values in the range -${"9".repeat(1023)} to ${"9".repeat(1024)}.
These obviously do not fit in an i64, so we were previously failing to
parse the attribute.
We will now cap the parsed value to the numeric limits of an i64, after
ensuring that the attribute value is indeed a number.
Previously, attempting to get the computed value for a
grid-template-rows or grid-template-columns property would cause a crash
if the element had no associated paintable.
At least on my Linux machine using zsh, this line was interpreted as
( cd "$build_dir" || echo ... ) && exit 1
instead of the intended
cd "$build_dir" || ( echo ... && exit 1 )
...meaning that it always exited regardless of whether it found the
build dir or not. So, let's make the intended precedence explicit.
Function is defined as `round(<rounding-strategy>?, A, B?)`
With this change resolved type is `typeof(resolve(A))`, instead of
`typeof(A)`.
For example `round(up, 20%, 1px)` with 200px percentage basis is now
correctly resolved in 40px instead of 40%.
Progress on https://www.notion.so/ landing page.
The `calculate_inner_width()` and `calculate_inner_height()` resolve
percentage paddings using the width returned by
`containing_block_width_for()`. However, this function does not account
for grids where the containing block is defined by the grid area to
which an item belongs.
This change fixes the issue by modifying `calculate_inner_width()` and
`calculate_inner_height()` to use the already resolved paddings from the
layout state. Corresponding changes ensure that paddings are resolved
and saved in the state before box-sizing is handled.
As a side effect, this change also improves abspos layout for BFC where
now paddings are resolved using padding box of containing block instead
of content box of containing block.
Fixes yet another case of GFC bug, where Node::containing_block() should
not be used for grid items, because their containing block is grid area
which is not represented in layout tree.
We currently implement the official cookie RFC, which was last updated
in 2011. Unfortunately, web reality conflicts with the RFC. For example,
all of the major browsers allow nameless cookies, which the RFC forbids.
There has since been draft versions of the RFC published to address such
issues. This patch implements the latest draft.
Major differences include:
* Allowing nameless or valueless (but not both) cookies
* Formal cookie length limits
* Formal same-site rules (not fully implemented here)
* More rules around cookie domains
Although the parameter is named "available size," it is always supposed
to represent the containing block size whenever it has a definite value.
Therefore, it is possible to simply use this value instead of performing
a containing block lookup.
This change actually improves correctness for grid items whose
containing block is defined by the grid area, as
`Node::containing_block()` does not account for this.
Change try_compute_width() to check whether min-width/max-width or width
is auto instead of always using `computed_values.width()`.
`grid/min-max-content.html` test is affected but it's progression.
Before this change, a formatting context was responsible for layout of
absolutely positioned boxes whose FC root box was their parent (either
directly or indirectly). This only worked correctly when the containing
block of the absolutely positioned child did not escape the FC root.
This is because the width and height of an absolutely positioned box are
resolved based on the size of its containing block, so we needed to
ensure that the containing block's layout was completed before laying
out an absolutely positioned box.
With this change, the layout of absolutely positioned boxes is delayed
until the FC responsible for the containing block's layout is complete.
This has affected the way we calculate the static position. It is no
longer possible to ask the FC for a box's static position, as this FC's
state might be gone by the time the layout for absolutely positioned
elements occurs. Instead, the "static position rectangle" (a concept
from the spec) is saved in the layout state, along with information on
how to align the box within this rectangle when its width and height are
resolved.
This change ensures that the value sanitization algorithm is run and
the text cursor is set to the correct position when the type attribute
of an input is changed.
If grid-template-rows or grid-template-columns queried for a box that is
not a grid container, the result should be computed value instead of
null.
Fixes crashing in inspector.
Previously, there was a bug in the specification that would cause an
assertion failure, due to the abort event being fired before all
dependent signals were aborted.
That's awkward, but getComputedStyle needs to return used track values
for gridTemplateColumns and gridTemplateRows properties. This change
implements it by saving style values with used values into layout state,
so it could be assigned to paintables during LayoutState::commit() and
later accessed by style_value_for_property().
I haven't seen it used in the wild, but WPT grid tests extensively use
it. For example this change helps to go from 0/10 to 8/10 on this test:
https://wpt.live/css/css-grid/layout-algorithm/grid-fit-content-percentage.html
Fixes implementation of the following line from the spec:
"However, limit the growth of any fit-content() tracks by their
fit-content() argument."
Now we correctly apply a limit to increased growth limit rather than to
the planned increase.
Change in "Tests/LibWeb/Layout/input/grid/fit-content-2.html" is a
progression and "Item as wide as the content." is actually as wide as a
content.
This change enables using the rebaseline-libweb-test script with Debug
and Sanitizer builds — and allows specifying which build to use when
using rebaseline-libweb-test to generate new test-expectations files.
The mechanism used is to check the BUILD_PRESET environment variable.
Otherwise, without this change, there’s no way to use the
rebaseline-libweb-test script with Debug and Sanitizer builds — except
by manually hacking the script locally to hardcode a directory name.
Instead of switching on the PropertyID and doing a boatload of
comparisons, we reorder the PropertyID enum so that all inherited
properties are in two contiguous ranges (one for shorthands,
one for longhands).
This replaces the switch statement with two simple range checks.
Note that the property order change is observable via
window.getComputedStyle(), but the order of those properties is
implementation defined anyway.

Before this change, we were cascading custom properties for each layer,
and then replacing any previously cascaded properties for the element
with only the set from this latest layer.
The patch fixes the issue by making each pass of the custom property
cascade add to the same set, and then finally assigning that set of
properties to the element.
