Grid specification https://www.w3.org/TR/css-grid-2/#z-order defines
special painting order for grid items which should be the same as for
defined for inline-blocks in CSS2.
If we run an inline script from the HTML parser, it may append a text
node to the current insertion point.
If there was text content immediately following the script element,
we would previously overwrite the script-inserted text content, due to
an oversight in the way we select an appropriate insertion point
This patch fixes the issue by only inserting parser content into
existing text nodes if they are empty.
This object is available as `window.internals` (or just `internals`) and
is only accessible while running in "test mode".
This first version only has one API: gc(), which triggers a garbage
collection immediately.
In the future, we can add more APIs here to help us test parts of the
engine that are hard or impossible to reach via public web APIs.
This could happen if a sequence of '0' parts was followed by a longer
sequence of '0' parts at the end of the host. The first sequence was
being used for the compress, and not the second.
For example, [1:1:0:0:1:0:0:0] was being serialized as: [1:1::1:0:0:0]
instead of [1:1:0:0:1::].
Fix this by checking at the end of the loop if we are in the middle of a
sequence of '0' parts that is longer than the current longest.
When toggling `display: none` on an element, it can go from having a
layout subtree to not having one. In the `none` case, we were previously
leaving stale layout nodes hanging off DOM nodes in the subtree.
These layout nodes could be queried for outdated information and
probably other things that we shouldn't allow.
Fix this by having TreeBuilder prune any old layout nodes hanging off
nodes in a subtree after its subtree root doesn't produce a layout node.
This is defined in the spec, but was missing in our table. Fix this, and
add a spec comment for what is missing. Also begin a basic text based
test for URL, so we can get some coverage of LibWeb's usage of URL too.
This fixes an assertion on https://amazon.com/ since WindowProxy
would advertise "0" as an own property key, but then act like it was
a bogus property when actually queried for it directly.
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.
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.
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. :^)
Fixes an assertion failure on https://twinings.co.uk/
We achieve this by making properties that accept a custom-ident value
skip the "someone else's vendor prefix" check for values that start with
a `-` character.
This fixes an issue where e.g `font-family: Arial, -apple-system` would
be rejected by the parser completely. We now treat `-apple-system` like
an identifier in such cases.
Also add `valid-types` metadata for the `font-family` property so this
actually works. :^)
This fixes an issue where a BOM at the head of a style sheet would be
passed verbatim to the parser, who would then interpret it as an ident
token and (after some confusion) fail to parse the first rule, but then
carry on with the rest of the sheet.
There were multiple bugs in the parsing algorithm for handling text
occurring inside a `table` element:
- When there was pending non-whitespace text inside a table, we only
flushed one token instead of all pending tokens.
- Also, we didn't even flush one of the right tokens, but instead the
token that caused the flush to happen.
- Once we started flushing the right tokens, it turned out we had not
yet implemented character insertion points expressed as "before X".
- Finally, we were not exiting the "in table text" mode after flushing
pending tokens, effectively getting us stuck in that mode until EOF.
The CSS box-shadow property takes 2-4 properties that are `<length>`s,
those being:
- offset-x
- offset-y
- blur-radius
- spread-radius
Previously these were resolved directly to concrete Lengths at parse
time, but now they will be parsed as LengthStyleValues and/or
CalculatedStyleValues and be stored that way until styles are later
resolved.
These are superseded by headless-browser running these tests in a single
process, and aren't used by CI anymore. It's a bit confusing having them
still around so let's be rid of them.
Prior to this commit, PropertyOwningCSSStyleDeclaration::serialized()
did not include custom properties, which lead to an incomplete
`cssRule.cssText` result.
This commit makes that class also serialize the custom properties and
place them before the regular properties in the rule text.
On macOS, CMake incorrectly tries to add and/or remove rpaths from files
that it has already processed when it performs installation. Setting the
rpaths during the build process ensures that they are only set once, and
as a bonus, makes installation slightly more performant.
Fixes#10055.
Generated iterator prototypes already have the IteratorPrototype as
their prototype, but we were incorrectly hijacking them and rerouting
to ObjectPrototype.
Regressed in cfe663435e.
The main differences between our current implementation and the spec
are:
* The title element need not be a child of the head element.
* If the title element does not exist, the default value should be
the empty string - we currently return a null string.
* We've since added AOs for several of the spec steps here, so we
do not need to implement those steps inline.
I was not aware of this framework back when implementing this back in
bc54560e59. Add in some basic tests for
this now that we are compliant with the specification.
Previously this was compiled to require an object despite the IDL file
specifying 'optional'.
This commit makes IDLGenerator respect this modifier, and fixes the only
affected instance.
Although we translate e.g `block` to `block flow` for internal use in
the engine, CSS-DISPLAY-3 tells us to use the short form in
serializations for compatibility reasons.
This adds 9 points to our score on https://html5test.com/ :^)
This allows us to create "text tests" in addition to "layout tests".
Text tests work the same as layout tests, but dump the document content
as text and exit upon receiving the window "load" event.
