This was resulting in a whole lot of rebuilding whenever a new IDL
interface was added.
Instead, just directly include the prototype in every C++ file which
needs it. While we only really need a forward declaration in each cpp
file; including the full prototype header (which itself only includes
LibJS/Object.h, which is already transitively brought in by
PlatformObject) - it seems like a small price to pay compared to what
feels like a full rebuild of LibWeb whenever a new IDL file is added.
Given all of these includes are only needed for the ::initialize
method, there is probably a smart way of avoiding this problem
altogether. I've considered both using some macro trickery or generating
these functions somehow instead.
This commit introduces a WEB_SET_PROTOTYPE_FOR_INTERFACE macro that
caches the interface name in a local static FlyString. This means that
we only pay for FlyString-from-literal lookup once per browser lifetime
instead of every time the interface is instantiated.
Instead of crashing with a TODO() on half of the test cases generated by
Domato, let's just return a zeroed-out SVGAnimatedLength or
SVGAnimatedNumber from getters that return them.
We'll eventually have to implement these correctly, but crashing is not
productive since it blocks us from finding other issues.
We cannot port over Optional<FlyString> until the IDL generator supports
passing that through as an argument (as opposed to an Optional<String>).
Change to FlyString where possible, and resolve any fallout as a result.
This commit un-deprecates DeprecatedString, and repurposes it as a byte
string.
As the null state has already been removed, there are no other
particularly hairy blockers in repurposing this type as a byte string
(what it _really_ is).
This commit is auto-generated:
$ xs=$(ack -l \bDeprecatedString\b\|deprecated_string AK Userland \
Meta Ports Ladybird Tests Kernel)
$ perl -pie 's/\bDeprecatedString\b/ByteString/g;
s/deprecated_string/byte_string/g' $xs
$ clang-format --style=file -i \
$(git diff --name-only | grep \.cpp\|\.h)
$ gn format $(git ls-files '*.gn' '*.gni')
With this change, we now have ~1200 CellAllocators across both LibJS and
LibWeb in a normal WebContent instance.
This gives us a minimum heap size of 4.7 MiB in the scenario where we
only have one cell allocated per type. Of course, in practice there will
be many more of each type, so the effective overhead is quite a bit
smaller than that in practice.
I left a few types unconverted to this mechanism because I got tired of
doing this. :^)
This commit removes DeprecatedString's "null" state, and replaces all
its users with one of the following:
- A normal, empty DeprecatedString
- Optional<DeprecatedString>
Note that null states of DeprecatedFlyString/StringView/etc are *not*
affected by this commit. However, DeprecatedString::empty() is now
considered equal to a null StringView.
We currently store a StringView into the DeprecatedString provided to
SVGUseElement::attribute_changed. This is a temporary string created by
String::to_deprecated_string, so this StringView is always a dangling
pointer.
Instead, since this string value is an ID and is primarily used as a
FlyString, store it as a FlyString from the get-go.
We needed to keep the old versions of these functions around before all
of the IDL interfaces were ported over to new AK String, but now that is
done, we can remove the deprecated versions of these functions.
This should allow us to add a Element::attribute which returns an
Optional<String>. Eventually all callers should be ported to switch from
the DeprecatedString version, but in the meantime, this should allow us
to port some more IDL interfaces away from DeprecatedString.
Rather than modify the transform of the parent (which could change
independently), this adds a new override element_transform() where
element specific tranfroms can be applied. This will always stay in
sync with the attributes.
A ref test comparing a .svg and .html version of the same file is
added as due to differences in attribute parsing order, the .svg version
was previously drawn incorrectly.
Fixes#20859
I'm about to make StackingContext traverse the paintable tree instead of
actually traversing the layout tree, and it turns out we were not
creating paintables for these SVG elements.
Also switch them to Layout::Box instead of the default InlineNode to
make the trees look a bit less weird. Ultimately, we should do something
specialized for these subtrees, but for now this'll do.
Stop worrying about tiny OOMs. Work towards #20449.
While going through these, I also changed the function signature in many
places where returning ThrowCompletionOr<T> is no longer necessary.
The `document_fully_loaded` event should use the adjective "completely"
so as to match the spec and code convention. See
`Document::is_completely_loaded` and `m_completely_loaded_time`.
