The spec has a general rule for this, which is roughly that "If it's not
a falsey value, it's true". However, a couple of media-features are
always false, apparently breaking this rule. To handle that, we have an
array of false keywords in the JSON, instead of a single keyword. For
those always-false media-features, we can enter all their values into
this array.
Gets us 2 more WPT subtest passes.
Despite what the spec suggests, modern displays are not progressive, and
WPT expects `@media (scan: progressive)` to fail. So, return `none`
here to accurately represent that.
I've left a FIXME in case we can detect the display type from the OS
somehow in the future.
Gets us 4 WPT subtest passes.
Previously, for `foo < 30px` ranges, we'd flip them and store them as
`30px > foo` instead. That worked fine, but means the serialization is
wrong. So instead, keep them in their original form.
I experimented with giving Range two optional sub-structs instead of 4
optional members, thinking it would be smaller - but it's actually
larger, because the two Optional<Comparison>s fit snugly together. So,
the slightly-goofy all-Optionals remains.
This gets us 2 WPT passes that I'm aware of.
Instead of rejecting invalid media-feature values at parse time, we are
expected to parse them, and then treat them as Unknown when evaluating
their media query. To implement this, we first try to parse a valid
value as before. If that fails, or we have any trailing tokens that
could be part of a value, we then scoop up all the possible
ComponentValues and treat that as an "unknown"-type MediaFeatureValue.
This gets us 66 WPT passes.
Functionally this is the same before, as result is always True or False
before this point, and `True && Foo` evaluates to `Foo`. But this is
more clearly correct, instead of correct by coincidence.
This commit on its own has no observable behaviour changes, as we still
only return True or False, but for the next commit, we'll need to be
able to return the Unknown state here, and without this change we'd get
regressions.
This is very hacky and wrong, but it means there's one place to fix,
instead of one for UnresolvedStyleValue, and one for invalid
MediaFeatureValues which I'm about to implement.
The current spec defines this simply as `<ident>`, but does apparently
serialize as lowercase.
Because of this change, we no longer need to care about the deprecated
media types, as they all behave the same as unknown ones.
We still keep an enum around for KnownMediaType, to avoid repeated
string comparisons when evaluating it.
Gets us 2 WPT passes.
When restructuring a block node inside an inline parent, if the
nearest block ancestor is `display: inline-block`, ensure that
the generated anonymous wrappers also have `display: inline-block`.
This fixes layout issues with block elements nested
inside inline-block elements.
Previously floats would be placed next to the highest float that
fitted the new float on its line. However, this violates the rule
that floats should be placed under the preceding float if it does
not fit next to it.
This is functionaly the same since caller_context is the topmost
execution context on the stack, but makes it more clear that
we are directly inheriting the strict mode from the caller context
when pushing the next context on to the stack.
We are required to delay the load event while any fetch is ongoing. We
currently have a very hacky re-fetch for images to go through the shared
resource request infrastructure. We must delay the load event during
this re-fetch.
This becomes an issue in an upcoming commit to import the acid2 test.
If we queue the <object> representation task multiple times in a row, we
would end up clearing the delayer after the first task completed. We
must continue delaying the load event until the last task completes.
This becomes an issue in an upcoming commit to import the acid2 test.
In a recent refactor of font styles, the new FontStyleStyleValue was
introduced; however, the `to_font_slope()` function was not changed to
understand this new type. When it tries to convert such a font style to
a keyword, it fails. We then rendered the wrong font-style.
When an element's ID is removed we only want to remove it from
`m_potentially_named_elements` if it is not also considered a
potentially named element due to it's name content attribute.
It is currently possible to hit this limit on pages with large numbers
of images. This temporary workaround prevents some WPT tests with large
numbers of images from failing.
We were previously only testing for network errors, which includes e.g.
DNS resolution and connection errors. It does not include e.g. HTTP 404
responses, which is exercised by Acid 2.
This begins implementation on form-associated custom elements.
This fixes a few WPT tests which I'm importing.

Which has an optmization if both size of the string being passed
through are FlyStrings, which actually ends up being the case
in some places during selector matching comparing attribute names.
Instead of maintaining more overloads of
Infra::is_ascii_case_insensitive_match, switch
everything over to equals_ignoring_ascii_case instead.
The spec isn't super clear on what disentagling a MessagePort means. But
we are required to send all pending messages before closing the port.
This is a bit tricky because the transport socket performs writes on a
background thread. From the main thread, where the disentanglement will
occur, we don't really know the state of the write thread. So what we do
here is stop the background thread then flush all remaining data from
the main thread.
* We need the full definition of IPC::File in the header.
* We need(ed) Core::System in the header. Move AutoCloseFileDescriptor's
ctor and dtor out-of-line to avoid this.
Fixes a bug that reproduces with the following steps:
1. Create an object with a getter for property "a" in its prototype,
where the getter adds an "a" property to the object itself.
2. Call the "a" getter in a loop for the first time. This triggers
caching of metadata indicating that the "a" property is located in
the prototype chain.
3. Call the "a" getter in a loop for the second time. Oops, the cache
says the getter is in the prototype chain, but the object now
also has its own "a" property that was added by the first getter
call.
We now explicitly enabling support for the minimum libraries needed
to build and run the AK testsuite. 81/82 tests are running and
passing. The exception is LexicalPath, as some path behaviour on
Windows is different than Unix, so the current tests will have lots of
platform specific failures. The implementer of LexicalPathWindows
recommended windows-specific tests here, so I will do that in a
follow up.
