Implement transfer logic for ArrayBuffer and ResizableArrayBuffer.
Change TransferDataHolder data type to Vector<u32> to reuse existing
serialization infrastructure.
Fix 5 WPT tests in `window-postmessage.window.html` that relates to
transport.
Fix `LibWeb/Text/input/Worker/Worker-postMessage-transfer.html`.
The latter is currently ignored due to flakiness, no rebaseline is
needed.
During serialization with transfer, initialize memory with known index
and initialize Serializer at position that dependent on the memory.
This is mandatory to make ArrayBuffer transport to work. It also happens
to fix 4 WPT tests, that are related to curcular references during
serialization.
We have to list the set of allowed values for the DOMTokenList to not
throw when asking if one is supported.
This fixes an issue where YouTube embeds would hang indefinitely trying
to report an endless series of exceptions, seen on https://null.com/
The 'reason' was getting initialized to 'empty' state when not
provided through the constructor, which results in a crash when
accessed through throw_dom_exception_if_needed in the generated
IDL getter.
This allows us to disable test output, which performs expensive assert
tracking. This was making our imported tests run significantly slower
than tests run via `WPT.sh`.
Formatting the output ourselves also allows us to remove unnecessary
information from the test output.
This commit also rebaselines all existing imported WPT tests to follow
the new format.
Size negotiation should not occur for other viewports, such as iframe,
since that would allow content inside the iframe to affect the size of
the iframe in the containing document.
300 new subtest passes on WPT. :^)
According to the HTML specification, the `size` attribute of an input
element must be a valid non-negative integer greater than zero. If the
value is invalid or set to `0`, the default size of `20` should be used.
This small change fixes one issue identified in
https://wpt.live/html/rendering/widgets/input-text-size.html
The WPT test suite was also automatically imported.
This isn't directly in the spec, but since replaceChild is implemented
in terms of remove + insert, the removal step may cause arbitrary code
to execute, and so we have to verify that the replaceChild inputs still
make sense afterwards, before doing the insertion.
This roughly matches what WebKit does, and makes a bunch of HTML parsing
tests in WPT stop asserting.
In particular, input character lookahead now knows how to stop at the
insertion point marker if needed.
This makes it possible to do amazing things like having document.write()
insert doctypes one character at a time.
If we reach the insertion point at the same time as we switch to another
tokenizer state, we have to bail immediately without proceeding with the
next code point. Otherwise we'd fetch the next token, get an EOF marker,
and then proceed as if we're at the end of the input stream, even though
more data may be coming (with more calls to document.write()..)
In the case where we had a preferred aspect ratio and a natural height
but no natural width, we'd get into ping-ponging infinite recursion by
trying to find the width to resolve the height to resolve the width to
resolve the height...
This one is particularly weird as there's a priority order, and we even
have to look at attributes from the container element if we're inside a
subframe.
This shouldn't just be a simple reflection of the label attribute.
It also needs fallback to the HTMLOptionElement.text property if the
label attribute is absent.
We were neglecting to check the namespace when looking for a specific
type of element on the stack of open elements in many cases.
This caused us to confuse HTML and SVG elements.
Element::tag_name() returns an uppercased string for HTML elements,
which is usually not what's expected by the parser algorithms that look
at tag names.
This fixes structured serialization of DataView. It was expected
to be uniform with TypedArray, which returns u32 for byte_offset().
This was covered by a number of WPT infrastructure tests, which this
commit also imports.
It's actually possible for there to be no adjusted current node, when
the stack of open elements is empty. This was covered by one of the WPT
parsing tests.
