This fixes 3/4 of the remaining test failures in wpt/png/apng. Also,
about half of the APNG files on
https://commons.wikimedia.org/wiki/Category:Animated_PNG_files
used to be broken, and they all seem to work properly now :^)
I also refactored the code to be (at least to me) simpler and more
similar to what the spec describes. As a nice side effect, there are now
fewer lines of code than before.
Lastly, I replaced DeprecatedPainter with Painter.
The current shadow realm constructor implementation was based off a
merge request to the shadow realm proposal for integration into the
web platform. However, this merge request had a bug which we had
applied a workaround for by popping off the execution stack.
Since then, the spec has had an update of:
https://github.com/tc39/proposal-shadowrealm/commit/28b0cc
Which closer aligned the mainline spec to the proposed merge request.
Now, the original shadow realm proposal merge request has been closed
and a new one has been reopened with a much more minimal set of changes
that merely adds extra arguments to HostInitializeShadowRealm, which
this commit aligns with.
Noone needs to use this any more :^)
This is somewhat AD-HOC in the constructor as it is based on an open
shadow realm merge request, but applies the intent of the change without
any change in behaviour.
The use of extract_parameter_arguments_and_body() here is to make things
a little less awkward. If we were to exactly follow spec there would be
an awkward handling of the case that no arguments were provided and we
needed to provide an empty string.
To do this, we would need to either:
- Provide an Optional<Value> for bodyString to CreateDynamicFunction
- Create a new empty PrimitiveString wrapped in a JS Value.
Either case is somewhat awkward. Instead, just refactor this logic
outside of CreateDynamicFunction and make the caller do it.
Otherwise, this commit prepares for the new definition of
HostEnsureCanCompileStrings.
All callers have been made async, i.e. they now all provide a completion
callback. Let's make the callback required to discourage any future sync
usage.
If the attribute value is the empty string `(lang="")`, the language
is set to unknown. `lang` attribute higher up in the document tree
will no longer be applied to the content of that element.
This updates the CSS parser to support the keyword 'none' in the CSS4
color functions. The underlying CSSColorValue already supports this
keyword, meaning the parser can instantiate the color directly.
We track this node ID to navigate to a default element when opening the
Inspector. So for all intents and purposes, <frameset> and <body> should
be treated the same.
We guarded one step against a null navigable, but the very next step
also needs to be protected. Let's just abort early instead. This was
caught by the following imported WPT test:
html/dom/elements/the-innertext-and-outertext-properties/innertext-setter.html
This test adds a <frame> element and immediately removes it, but the
task to process the src attribute is already queued. Note that <iframe>
would have the same issue, but this test does not include them.
NavigableContainer is our home grown concept which already contains the
AOs needed for frame and iframe elements. This patch simply aligns our
HTMLFrameElement implementation with this class.
A couple of notes:
1. The <script> in the <head> element is intentional. The <frameset>
element effectively takes the place of the <body> element, and we
cannot add a <script> to a <frameset> element.
2. We don't render <frameset> or <frame> at all. Rendering is defined
in the following spec:
https://html.spec.whatwg.org/multipage/rendering.html#frames-and-framesets
3. If you load the test page in your browser, you won't see anything,
regardless of (2). Our test infra adds a <pre> element to the "body"
element (which is the <frameset> element here). Such children will
never be rendered. In the future, we could come up with something
better for our test infra to do, but this isn't important anyways
for this test - we can still grab the <pre> element's innerText.
This change allows the test list given to “WPT.sh run” to include full
filesystem relative or absolute pathnames. That facilitates using tab
completion in the shell to browse for pathnames, and also facilitates
copy-paste of full filesystem pathnames. For example:
./Meta/WPT.sh run Tests/LibWeb/WPT/wpt/dom/historical.html
./Meta/WPT.sh run /opt/ladybird/Tests/LibWeb/WPT/wpt/dom/historical.html
Otherwise, without this change, the test list can’t include full
filesystem pathnames, but is instead limited to only path fragments that
specify WPT subdirectory pathnames — which doesn’t allow for tab
completion on pathnames in the shell, nor copy-paste of full pathnames.
Unfortunately, there isn't an exact spec method to get the rendered text
of an element, including its shadow DOM. The WebDriver spec requires
just doing exactly what Selenium does.
This patch does not implement this, but is a step in the right direction
as we will now handle text transforms.
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.
Previously, callers were passing the size in bytes, but the method
expected bits. This caused a crash in LibCrypto when verifying the key
size later on.
Also make the naming of local variables and parameters a little more
clear between the different AES algorithms :^)
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.
