This constructor was easily confused with a copy constructor, and it was
possible to accidentally copy-construct Objects in at least one way that
we dicovered (via generic ThrowCompletionOr construction).
This patch adds a mandatory ConstructWithPrototypeTag parameter to the
constructor to disambiguate it.
This commit teaches BindingsGenerator to generate depfiles, which can be
used by CMake to ensure that bindings are properly regenerated when
imported IDL files change.
Two new options, `--depfile` and `--depfile-target` are added.
- `--depfile` sets the path for the dependency file.
- `--depfile-target` lets us set a target name different than the output
file in the depfile. This option is needed because generated files are
first written to a temporary file, but depfiles have to refer to the
final location.
These are analogous to GCC's `-MF` and `-MT` options respectively. The
depfile's syntax matches the ones generated by GCC.
Note: This changes the minimal required CMake version to 3.20 if the
Make generator is used, and to 3.21 for the Xcode generator. Ninja is
not affected.
This generally seems like a better name, especially if we somehow also
need a better name for "read the entire buffer, but not the entire file"
somewhere down the line.
For example, Document.getSelection returns Selection, which is in the
Selection namespace.
Namespaces.h has Linus' copyright since he changed the "is_one_of" list
to an Array.
Note that js_rope_string() has been folded into this, the old name was
misleading - it would not always create a rope string, only if both
sides are not empty strings. Use a three-argument create() overload
instead.
This will make it easier to support both string types at the same time
while we convert code, and tracking down remaining uses.
One big exception is Value::to_string() in LibJS, where the name is
dictated by the ToString AO.
We have a new, improved string type coming up in AK (OOM aware, no null
state), and while it's going to use UTF-8, the name UTF8String is a
mouthful - so let's free up the String name by renaming the existing
class.
Making the old one have an annoying name will hopefully also help with
quick adoption :^)
This was forgotten to be added in the LibWeb GC conversion.
This caused some brand checks to fail in skribbl.io's JavaScript and
thus caused unexpected exceptions.
Due to the way we lazily construct prototypes and constructors for web
platform interfaces, it's possible for nested GC allocation to occur
while GC objects have been allocated but not fully constructed.
If the garbage collector ends up running in this state, it may attempt
to call JS::Cell::visit_edges() on an object whose vtable pointer hasn't
been set up yet.
This patch works around the issue by deferring GC while intrinsics are
being brought up. Furthermore, we also create a dummy global object for
the internal realm, and populate it with intrinsics. This works around
the same issue happening when allocating something (like the default UA
stylesheets) in the internal realm.
These solutions are pretty hacky and sad, so I've left FIXMEs about
finding a nicer way.
Get rid of the bespoke NavigatorObject class and use the modern IDL
strategies for creating platform objects to re-implement Navigator and
its associcated mixin interfaces. While we're here, implement it in a
way that brings WorkerNavigator up to spec :^)
This new code generator takes all the .idl files in LibWeb, looks for
each top level interface in there with an [Exposed=Foo] attribute, and
adds code to add the constructor and prototype for each of those exposed
interfaces to the realm of the relevant global object we're initialzing.
It will soon replace WindowObjectHelper as the way that web interfaces
are added to the Window object, and will be used in the future for
creating proper WorkerGlobalScope objects for dedicated and shared
workers.
Instead, create a tree of Parsers all pointing to a top-level Parser.
All module imports and interfaces are stored at the top level, instead
of in a static map. This allows creating multiple IDL::Parsers in the
same process without them stepping on each others toes.
An "inherit attribute" calls an ancestor's getter with the same name,
but defines its own setter. Since a parent class's public methods are
exposed to child classes, we don't have to do any special handling here
to call the parent's methods, it just works. :^)
This includes punting on the actual file picker implementation all the
way out to the PageClient. It's likely that some of the real details
should be implemented somewhere closer, like the BrowsingContext or the
Page, but we'll get there.
For now, this allows https://copy.sh/v86 to load the emulation of the
preselected images all the way until it hits a call to
URL.createObjectURL.
In this generator change, we introduce a new factory method for bound
LibWeb objects that takes a JS::Realm instead of Web::HTML::Window.
The two methods are allowed to co-exist at this point, but the option to
take an HTML::Window will be removed once all clases are converted to
the new API.
We also start using the new Bindings::ensure_web_[prototype/constructor]
helpers from the Bindings/Intrinsics class so that we can eventually
remove the helpers from Window.h for the same.
IDL dictionary members are nullable by default (unless marked as
`required`) and should not get any value assigned unless one was
provided by the userland code that isn't undefined, or if the member has
a default value.
This is so that we can use Optional<T> in the internal representation
and check for "is present" via Optional::has_value().
The SourceGenerator's @else@ mapping is only set in the second iteration
of the loop, causing the generated return for unrecognized values to not
be guarded by an else statement.
We can simply use a hardcoded 'else' here, @else@ is only to create the
first comparison as a plain 'if' and subsequent ones as 'else if'.
Without this, the generated DOMExceptionConstructor does not refer to
the WebIDL::DOMException with its fully qualified name. This caused an
ambiguity error on my machine.
Let's stop putting generic types and AOs from the Web IDL spec into
the Bindings namespace and directory in LibWeb, and instead follow our
usual naming rules of 'directory = namespace = spec name'. The IDL
namespace is already used by LibIDL, so Web::WebIDL seems like a good
choice.
This code generator no longer creates JS wrappers for platform objects
in the old sense, instead they're JS objects internally themselves.
Most of what we generate now are prototypes - which can be seen as
bindings for the internal C++ methods implementing getters, setters, and
methods - as well as object constructors, i.e. bindings for the internal
create_with_global_object() method.
Also tweak the naming of various CMake glue code existing around this.
This name more accurately reflects what we are checking. Also add an
explanatory note that only a hand-curated subset of platform object
types is checked in the absence of a full generated list.
This fixes an issue on Twitter where they were instantiating an
IntersectionObserver with a null root. The root IDL type is
`(Element or Document)?` so null needs to be allowed.
