Before this change, we were doing it after every layout, which meant
that already-propagated overflow could be propagated again, which led to
incorrect scrolling behavior.
Consider the following:
JsonValue value { JsonValue::Type::Object };
value.as_object().set("foo"sv, "bar"sv);
The JsonValue(Type) constructor does not initialize the underlying union
that stores its value. Thus JsonValue::as_object() will A) refer to an
uninitialized union member, B) deference that member.
This constructor only has 2 users, both of which initialize the type to
Type::Null. Rather than implementing unused functionality here, replace
those uses with the default JsonValue constructor, and remove the faulty
constructor.
Previously we assumed a default precision of 6, which made the printed
values quite odd in some cases.
This commit changes that default to print them with just enough
precision to produce the exact same float when roundtripped.
This commit adds some new tests that assert exact format outputs, which
have to be modified if we decide to change the default behaviour.
Previously, all SVG <text> elements were zero-sized boxes, that were
only actually positioned and sized during painting. This led to a number
of problems, the most visible of which being that text could not be
scaled based on the viewBox.
Which this patch, <text> elements get a correctly sized layout box,
that can be hit-tested and respects the SVG viewBox.
To share code with SVGGeometryElement's the PathData (from the prior
commit) has been split into a computed path and computed transforms.
The computed path is specific to geometry elements, but the computed
transforms are shared between all SVG graphics elements.
This removes the awkward hack to recompute the layout transform at paint
time, and makes it possible for path sizes to be computed during layout.
For example, it's possible to use relative units in SVG shapes (e.g.
<rect>), which can be resolved during layout, but would be hard to
resolve again during painting.
The slugify function is used to convert input into URL-friendly slugs.
It processes each character in the input, keeping ascii alpha characters
after lowercase and replacing non-alphanum characters with the glue
character or a space if multiple spaces are encountered consecutively.
The resulting string is trimmed of leading and trailing whitespace, and
any internal whitespace is replaced with the glue character.
It is currently used in LibMarkdown headings generation code.
Passing a value of a type different than number or length-percentage
to transform-origin returned a null pointer, and we didn't take care
of that path before.
This patch fixes a crash caused by an incorrect CSS declaration, such as
`transform-origin: "center"`.
Fixes#21609
The current helpers assume that a valid URL is a full URL (i.e. contains
the "://" separator between the scheme and domain). This isn't true, as
"file:" alone is parsed as a valid URL.
We must also avoid simply searching for the parsed public suffix in the
original URL string. For example, "com" is a public suffix. If we search
for that in the URL "com.com", we will think the public suffix starts at
index 0.
Changing `try_compute_width()` to return width and margins, instead of
mutating them in the box's state makes it works in cases when box has
min-width or max-width and this function needs to be called multiple
times.

Instead of implementing this inline, put it into a function. Use this
new function to correctly implement shortening paths for some places
where this logic was previously missing.
Before these changes, the pathname for the included test was incorrectly
being set to '/' as we were not considering the windows drive letter.
An error is now returned if `numTables` is zero or greater than 4096.
While this isn't explicitly mentioned in the specification, subsequent
calculations will be incorrect if the value falls outside this range.
As spec comment in the code says we should use item’s max-content
contribution to calculate flex fraction.
Likely, it was calculate_max_content_size() because we didn't have
calculate_max_content_contribution() when this function was implemented
initially.
Previously, attempting to update an ext2 inode with a UID or GID
larger than 65535 would overflow. We now write the high bits of UIDs
and GIDs to the same place that Linux does within the `osd2` struct.
Rewrites the grid area building to accurately identify areas that span
multiple rows. Also now we can recognize invalid areas but do not
handle them yet.
