This patch fixes the value of a module map entry being wrong in the
callbacks invoked in the set call. Previously we would set the value
in only after invoking the callbacks, leading to crashes when a
callback implementation would rightfully assume the value to be set
already.
Resolves#20994
Fixes two places in child navigable destroy procedure where we used
content navigable instead of container's navigable.
With this change, iframe's nested histories are actually destroyed
along with the document that created them.
This change addresses the bug where images unable to load when the
reload button in the UI is clicked repeatedly. Before this fix, it was
possible to use SharedImageRequests across multiple documents. However,
when the document that initiated the request is gone, tasks scheduled
on the event loop remain in the fetching state because the originating
document is no longer active. Furthermore, another reason to prohibit
the sharing of image requests across documents is that the "Origin"
header in an image request is dependent on the document.
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.
Window.h is a rather heavy file, so let's try not to include it in
header files when we can!
Element.h now also includes LibWeb/Bindings/Intrinsics.h, but that's
just out of my laziness. Most if not all objects call
`Bindings::ensure_web_prototype<>()` anyway, so I don't think we would
gain much by sticking the header to source files instead.
These functions all have a very common case that can be dealt with a
very simple inline check, often avoiding the need to call an out-of-line
function. This patch moves the common case to inline functions in a new
ValueInlines.h header (necessary due to header dependency issues..)
8% speed-up on the entire Kraken benchmark :^)
This function must return true if the object may intercept and customize
access to indexed properties (properties where the property name is a
non-negative integer.)
This will be used to implement fast path optimizations for array-like
accesses in subsequent commits.
Renaming the DeprecatedString version of this function to
deprecated_tag_name. A FlyString is used here as we often need to
perform equality checks here, and the HTMLParser already has tag_name as
a FlyString.
Remove a FIXME while we're at it - we were already following the spec
there, and we still are :^)
Which pretty much needs to be done together due to the amount of places
where they are compared together.
This also involves porting over StackOfOpenElements over to FlyString
from DeprecatedFly string to prevent a gazillion calls to
`.to_deprecated_fly_string` calls in HTMLParser.
Renaming the DeprecatedString version of this function to
Element::get_deprecated_attribute.
While performing this rename, port over functions where it is trivial to
do so to the Optional<String> version of this function.
ImageStyleValue has a visit_edges() method, although it is not a
GC-allocated object. This is necessary because it owns a GC-allocated
ImageRequest that we want to visit, instead of using JS::Handle, to
avoid leaks. In the future, we might want to make StyleValue be
GC-allocated.
For now, this change adds missing visit_edges() calls for objects that
own ImageStyleValue.
This commit introduces 3 things:
- Support for the color type in HTMLInputElement itself
- A mechanism for handling non event loop blocking dialogs in Page
- The associated plumbing up to ViewImplementation
Frontends may add support for the color picker with the
ViewImplementation.on_request_color_picker function
Before the completion_steps for timer were casted from JS::SafeFunction
to Function in HTML::Timer constructor, which is incorrect because then
callback's captured GC-allocated objects are not protected from being
deallocated. Let's modify HTML::Timer to use JS::HeapFunction for the
callback instead.
By using Core::Timer that accepts Function instead of JS::SafeFunction
in Platform::Timer does we fix memory leak caused by circular
dependency of timer's callback and timer itself.
This change implements a step from the document's destroy procedure in
the specification, saying that all active timers should be cleared.
By doing this, we also fix the leaking of a document in case where we
have navigated away from a page that has scheduled timers that haven't
yet been triggered.
If a function that captures a GC-allocated object is owned by another
GC-allocated object, it is more preferable to use JS::HeapFunction.
This is because JS::HeapFunction is visited, unlike introducing a new
heap root as JS::SafeFunction does.
These functions are deferring to NamedNodeMap::get_attribute which
already takes a StringView. This changes also leads to finding some
places which were passing though a const char* instead of an entry from
Attribute names. Fix that where applicable, and switch to has_attribute
in some of those places instead of deprecated_attribute where
equivalent.
Ideally this should be taking a 'FlyString const&', but to continue
porting away from DeprecatedString, just leave a FIXME for now.
