We previously left it at the end of the final line, which caused the
next prompt to start offset to the right:
|$ foo^C

This commit makes LibLine move to the beginning of that line,
making it so the next prompt shows up at the beginning of the line:
|$ foo^C
|$
This removes a performance problem where we'd convert the style sheet's
default namespace from DeprecatedFlyString to FlyString once per rule
during selector matching.
The conversion now happens once, during CSS parse. It should eventually
be removed from there as well, but one step at a time. :^)
Allows the bytecode interpreter to call the builtins c++
implementation directly without making a javascript call
just as the JIT.
Kraken test speedups: imaging-gaussian-blur.js (1.5x) and
audio-oscillator.js (1.2x)
This method takes bytes as input and decompress everything to a
ByteBuffer. It uses two control codes (clear and end of data) as
described in the GIF, TIFF and PDF specifications.
`<iframe>`s only potentially delay the load event when their
`current_navigation_was_lazy_loaded` flag is false, so let's wire that
up to the flag's setter, and actually call it!
Four elements match the "potentially delay the load event" check in the
spec: `<embed>`, `<frame>`, `<iframe>`, and `<object>`. These four are
the same set of elements that are NavigableContainers (or will be once
we implement them) so let's put this logic there.
Note that other things can delay the load event, this is just the name
the spec gives to this particular behaviour.
`<iframe>` and `<img>` tags share the same spec for several aspects of
lazy-loading: how the `loading` attribute works, the "will lazy load
element" steps, and a member for storing the lazy-load resumption
steps. So let's share the implementation by using a base class.
This mostly involves moving things around. However, we also change the
`start_intersection_observing_a_lazy_loading_element()` method to take
a LazyLoadingElement, and operate on one, instead of always casting to
HTMLImageElement.
We do unfortunately have to do some shenanigans to make the cast work,
by adding a virtual function stub in DOM::Element.
We don't have the facilities to implement this method fully (namely, a
fully realized SharedArrayBuffer). But we can implement enough to
validate the values passed in by the user.

From test262 documentation, this flag means:
The test file should only be run when the [[CanBlock]] property of
the Agent Record executing the file is `false`.
This patch stubs out the accessor for that internal slot and skips tests
with the CanBlockIsFalse if that internal slot is true.
Provides a nicer experience on pages with large trees so that the window
isn't just a large blank screen while it is loading. Instead, send the
trees to the Inspector WebView once they have arrived and have been
transformed to HTML.
We Base64 encode the HTML to avoid needing to deal with all kinds of
nested quotes that may appear in the HTML. We could instead send the
JSON to the WebView, but generating the HTML in C++ feels a bit easier
for now.
If `SkipStackingContext` is returned we also need to restore saved
painter state because corresponding pop_stacking_context command that
is supposed to do that will be skipped.
Fixes https://github.com/SerenityOS/serenity/issues/22092
We currently create a shadow tree once for each DOM element that renders
with a shadow tree (e.g. <input>, <details>). If such an element is
removed from the DOM, we must remove its shadow tree. Otherwise, the
shadow tree will refer to the old document in perpetuity.
If the node is added back to a DOM, then recreate the shadow tree.
AbstractBrowsingContext has a subclass RemoteBrowsingContext without a
visit_edges() override (and it doesn't really need one). But currently,
we rely on subclasses visiting AbstractBrowsingContext's opener BC.
This adds a visit_edges() to AbstractBrowsingContext to explicitly visit
the opener BC itself.
This change ensures that the GPU painting executor follows the pattern
of the CPU executor, where the state is stored for each stacking
context, but a painter is created only for those with opacity.
Fixes crashing on apple.com because now save() and restore() are called
on correct painters.
Currently there is one root certificate which has expired, but it does
not have a common name, so we are simply printing "Certificate for by
is invalid, ...", which is less than useful. Instead we just print the
complete subject now, and remove printing the issuer, as root
certificates are always self-signed.
Some websites actually provide a SECP384 certificate which is signed
using a SHA256 hash. We assumed that SECP384 always used a SHA384 hash,
but this is not the case.
The Inspector will have a split view, where the top view is that of the
exisiting DOM and accessibility trees, and the bottom view is that of
the currently inspected node's style properties. This patch generalizes
some of the generated code to support having these 2 views.
The number of registers in a call frame never changes, so we can
allocate it at the end of the CallFrame object and save ourselves the
cost of allocating separate Vector storage for every call frame.
Instead of allocating these in a mixture of ways, we now always put
them on the malloc heap, and keep an intrusive linked list of them
that we can iterate for GC marking purposes.
This required setting things up so that all function objects can plop
a PrimitiveString there instead of an AK string.
This is a step towards making ExecutionContext easier to allocate.
