If no header includes the prototype of a function, then it cannot be
used from outside the translation unit it was defined in. In that case,
it should be marked as `static`, in order to avoid possible ODR
problems, unnecessary exported symbols, and allow the compiler to better
optimize those.
If this warning triggers in a function defined in a header, `inline`
needs to be added, otherwise if the header is included in more than one
TU, it will fail to link with a duplicate definition error.
The reason this diff got so big is that Lagom-only code wasn't built
with this flag even in Serenity times.
The spec says to just call the XML serialization algorithm, but it
returns the "outer serialization", and we need the "inner" one. Let's
just concatenate serializations of children; then the result produced is
similar to one from Blink or Gecko.
This method puts the given node and all of its sub-tree into a
normalized form. A normalized sub-tree has no empty text nodes and no
adjacent text nodes.
These methods were overriding properties specified by the EventInit
property bags in the constructor for WheelEvent and MouseEvent.
They appear to be legacy code and no longer relevant, as they would have
been used for ensuring natively dispatched events had the correct
properties --- This is now done in separate create methods, such as
MouseEvent::create_from_platform_event.
This fixes a couple WPT failures (e.g. in
/dom/events/Event-subclasses-constructors.html)
The first time Document learns its viewport size, we now suppress firing
of the resize event.
This fixes an issue on multiple websites that were not expecting resize
events to fire so early in the loading process.
Previously, unnecessary boundary checks were being done when
constructing the range objects used to represent find in page matches.
These checks are no longer performed leading to a significant speedup
when performing find in page queries on pages containing a lot of text.
The first step of the find in page algorithm is to walk the layout tree
of each document on the page and construct a list of strings against
which to search for matches.
Previously, this was being done for each new query, even when the
page content hadn't been updated. The output of this process is now
cached in the viewport node of the associated document. This ensures
that this process is no longer repeated unnceessarily.
Multiple APIs have moved from the DOM Parsing and Serialization spec to
HTML.
Updates spec URLs and comments.
Delete InnerHTML file:
- Make parse_fragment a member of Element, matching serialize_fragment
on Node.
- Move inner_html_setter inline into Element and ShadowRoot as per the
spec.
Add FIXME to Range.idl for Trusted Types createContextualFragment
This stuff has moved from a mixin defined by the DOM Parsing spec, over
to the HTML spec, where they are now defined as partial interfaces for
Element and ShadowRoot.
There's also some new functionality that we don't implement yet, so
patch marks them as FIXME properties.
And let the old shadow_root(), which was only supposed to be used by
bindings, be called shadow_root_for_bindings() instead.
This makes it much easier to read DOM code, and we don't have to worry
about when to use shadow_root_internal() or why.
LibLocale was split off from LibUnicode a couple years ago to reduce the
number of applications on SerenityOS that depend on CLDR data. Now that
we use ICU, both LibUnicode and LibLocale are actually linking in this
data. And since vcpkg gives us static libraries, both libraries are over
30MB in size.
This patch reverts the separation and merges LibLocale into LibUnicode
again. We now have just one library that includes the ICU data.
Further, this will let LibUnicode share the locale cache that previously
would only exist in LibLocale.
This implements most of the CloseWatcher API from the html spec.
AbortSignal support is unimplemented.
Integration with dialogs and popovers is also unimplemented.
Find in page will no longer match text that spans across block elements.
Previously, given the markup `WH<div>F</div>`, the query `WHF` would
find a match. We would now match `WH` and `F` separately, but not `WHF`.
Previously, the find in page function would fail to find text which was
split across multiple text nodes. For example, given the following
markup: `WH<span>F` the query `WHF` would previously fail to be
matched.
This is done by traversing all of the document's text nodes -
constructing a complete string to query against and keeping track of
the locations where that string is split across multiple nodes.
The spec doesn't explicitly forbid calling this when the document
doesn't have a node navigable, so let's handle that situation gracefully
by just returning an empty list of ancestors.
I hit this VERIFY somewhere on the web, but I don't know how to
reproduce it.
If the Document's navigable has been destroyed since we started this
timer, or it's no longer the active document of its navigable, we
shouldn't navigate to it.
The main intention of this change is to have a consistent look and
behavior across all scrollbars, including elements with
`overflow: scroll` and `overflow: auto`, iframes, and a page.
Before:
- Page's scrollbar is painted by Browser (Qt/AppKit) using the
corresponding UI framework style,
- Both WebContent and Browser know the scroll position offset.
- WebContent uses did_request_scroll_to() IPC call to send updates.
- Browser uses set_viewport_rect() to send updates.
After:
- Page's scrollbar is painted on WebContent side using the same style as
currently used for elements with `overflow: scroll` and
`overflow: auto`. A nice side effects: scrollbars are now painted for
iframes, and page's scrollbar respects scrollbar-width CSS property.
- Only WebContent knows scroll position offset.
- did_request_scroll_to() is no longer used.
- set_viewport_rect() is changed to set_viewport_size().
This is a hack needed to preserve current behaviour after making set
viewport_rect() being not async in upcoming changes.
For example both handle_mousedown and handle_mouseup should use the same
viewport scroll offset even though handle_mousedown runs focusing steps
that might cause scrolling to focused element:
- handle_mousedown({ 0, 0 })
- run_focusing_steps()
- set_focused_element()
- scroll_into_viewport() changes viewport scroll offset
- handle_mouseup({ 0, 0 })
This was used to convert markdown into HTML for display in the browser,
but no other browser behaves this way, so let's simplify things by
removing it.
(Yes, we could implement all kinds of "convert to HTML and display" for
every file format out there, but that's far outside the scope of a
browser engine.)
The DocumentTimeline constructor used the current millisecond time to
initialize its currentTime, but that means that a newly created timeline
would always have a different time value than other timelines that have
been through the update_animations_and_send_events function.
This allows searching for text with case-insensitivity. As this is
probably what most users expect, the default behavior is changes to
perform case-insensitive lookups. Chromes may add UI to change the
behavior as they see fit.
This allows the browser to send a query to the WebContent process,
which will search the page for the given string and highlight any
occurrences of that string.
Although refreshing is cheap, it was performed before each hit-testing
and was 2-4% in profiles on Discord and Twitter.
Now clip and scroll states are refreshed only if scroll offset has
changed.
Previously, we always cast to a HTMLInputElement when getting the value
of an auto directionality form associated element. This caused
undefined behavior when determining the directionality of an element
that wasn't a HTMLInputElement.
