The Qt style hints' color scheme can return ::Unknown, in which case we
still need to fall back to our 'old' method of using the luma component
of the background role color.
Before this change, skipping a word to the left in a non empty text
input element would crash when near the end of the text as the
offset + length of the substring would exceed the length of the string.
This was removed from the ShadowRealm HTML spec integration PR after my
suggestion as it is not used anywhere, and I don't believe it would ever
need to be used in the future or by other specs.
An environment settings object will return a copy to the URL. From a
quick glance, we could probably make an environment settings object
return a reference to one, but let's just change this code to make
a copy since its not safe to rely on that.
Prior to this commit LibTLS closed the connection but did not consider
it terminated after receiving and acknowledging a CloseNotify from the
server, which led to hangs in DoT (and possibly other users).
Instead of collecting all documents in a big vector and then filtering
the vector (twice!) with remove_all_matching(), we now pass a filter
callback to documents_in_this_event_loop_matching() and avoid all the
extra shuffling work.
Saw this stuff hogging ~20% of CPU time when profiling a WebContent
process in the middle of a WPT run.
Rather than accumulating margins into a vector, and then looping through
them when resolving the margin, it's much simpler to just update two
fields, and sum them when resolving.
When inserting a new utf-16 surrogate next to an existing surrogate
with replaceData, the surrogates would not get merged correctly into a
single code point. This is because internally the text data is stored
as utf-8, and the two surrogates would be converted seperately. This
has now been fixed by first recreating the whole string in utf-16 and
then converting it back to utf-8.
It's not the most efficient solution, but this fixes at least 6 WPT
subtests.
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.
This is necessary to avoid a circular reference when including
Serializable.h in DOMException.h.
This moves the definition of SerializationRecord, SerializationMemory,
and DeserializationMemory into LibWeb/Forward.h so that Serializable.h
only needs to include LibWeb/Forward.h.
Take record of the named capture group prior to parsing the group's
body. This requires removal of the recorded minimum length of the named
capture group directly, and now needs to be looked up via the group
minimu lengths table.
