This AO can be used instead of CreateReadableStream in cases where we
need to set up a newly allocated ReadableStream before initialization of
said ReadableStream, i.e. ReadableStream is captured by lambdas in an
uninitialized state.
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.
Before this change we were painting inner shadows lying outside of
viewport.
Improves painting performance on Github and Twitter where this command
is used a lot.
This struct had all members in CSSPixels and DevicePixels, but only the
latter are needed for painting.
Shrinks PaintOuterBoxShadowParams from 144 bytes to 72 bytes.
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.
We don't need intrinsic scale factors for Gfx::Bitmap in Ladybird,
as everything flows through the CSS / device pixel ratio mechanism.
This patch also removes various unused functions instead of adapting
them to the change.
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 closes the window at WebContent process startup where we were
relying on Gfx::FontDatabase having some resolvable value in its default
font query.
The Encoding specification maps ISO-8859-1 to windows-1252 and expects
the windows-1252 translation table to be used, which differs from
ISO-8859-1 for 0x80-0x9F.
Other contexts expect to get the actual ISO-8859-1 encoding, with 1-to-1
mapping to U+0000-U+00FF, when requesting it.
`decoder_for_exact_name` is introduced, which skips the mapping from
aliases to the encoding name done by `get_standardized_encoding`.
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.
Implements `table.get`, `table.set`, `elem.drop`, `table.size`,
and `table.grow`. Also fixes a few issues when generating ref-related
spectests. Also changes the `TableInstance` type to use
`Vector<Reference>` instead of `Vector<Optional<Reference>>`, because
the ability to be null is already encoded in the `Reference` type.
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.
