Because of the previous awkward factoring of Origin we had two
implementations of Origin serializing and creation. Move the
implementation of DOMURL::url_origin into URL::origin, and
instead use the implemenation of URL::Origin::serialize for
serialization (replacing URL::serialize_origin).
This happens to fix 8 URL subtests as the two implemenations had
diverged, and URL::serialize_origin was previously missing the spec
changes of: whatwg/url@eee49fd and whatwg/url@fff33c3
This closer matches specification - and removes any dependency on
LibWeb in the implementation of DOMURL::url_origin.
It is also one step closer to moving BlobURLRegistry to a singleton
process to match LibWeb's multiprocess Worker architecture.
While Origin is defined in the HTML spec - this leaves us with quite an
awkward relationship as the URL spec makes use of AO's from what is
defined in the HTML spec.
To simplify this factoring, relocate Origin into LibURL.
Before this change we were serializing them in a bogus 8-digit hex color
format that isn't actually recognized by HTML.
This code will need more work when we start supporting color spaces
other than sRGB.
Now we can register jobs and they will be executed on the event loop
"later". This doesn't feel like the right place to execute them, but
the spec needs some updates in this regard anyway.
Implements https://github.com/whatwg/html/pull/10007 which basically
moves style, layout and painting from HTML processing task into HTML
task with "rendering" source.
The biggest difference is that now we no longer schedule HTML event loop
processing whenever we might need a repaint, but instead queue a global
rendering task 60 times per second that will check if any documents
need a style/layout/paint update.
That is a great simplification of our repaint scheduling model. Before
we had:
- Optional timer that schedules animation updates 60 hz
- Optional timer that schedules rAF updates
- PaintWhenReady state to schedule a paint if navigable doesn't have a
rendering opportunity on the last event loop iteration
Now all that is gone and replaced with a single timer that drives
repainting at 60 hz and we don't have to worry about excessive repaints.
In the future, hard-coded 60 hz refresh interval could be replaced with
CADisplayLink on macOS and similar API on linux to drive repainting in
synchronization with display's refresh rate.
update_layout() need to be invoked before checking if layout node is
present, because layout not being updated might be the reason why layout
node doesn't exist yet.
...otherwise animated style invalidation will be skipped.
This change is a preparation before applying latest HTML event loop
procesing spec changes to avoid regressing our tests.
Fixes at least one WPT test that was previously timing out:
- html/semantics/document-metadata/the-base-element/base_target_does_not_affect_iframe_src_navigation.html
Horizontal scrollbar has to leave space at right edge for the vertical
scrollbar to fully extend from top-to-bottom edge of viewport. Before,
this was done by just moving it leftward beyond the edge of viewport.
Now, it gets scaled down appropriately to fit between left edge of
viewport & vertical scrollbar without clipping.
The existing rebaseline script is a bit limiting in that it can only
rebaseline a single test at a time. When making sweeping changes, this
patch will let us rebaseline any number of tests at once.
For example, in the following abbreviated test HTML:
<span>some text</span>
<script>println("whf")</script>
We would have to craft the expectation file to include the "some text"
segment, usually with some leading whitespace. This is a bit annoying,
and makes it difficult to manually craft expectation files.
So instead of comparing the expectation against the entire DOM inner
text, we now send the inner text of just the <pre> element containing
the test output when we invoke `internals.signalTextTestIsDone`.
There is an issue where gifs with many frames cannot be loaded, as each
bitmap is sent over IPC using a separate file descriptor, and there is
limit on the maximum number of descriptors per IPC message. Thus, trying
to load gifs with more than 64 frames (the current limit) causes the
image decoder process to die.
This commit introduces the BitmapSequence class, which is a thin wrapper
around the type Vector<Optional<NonnullRefPtr<Gfx::Bitmap>>> and
provides an IPC encode/decode routine that collates all bitmap data into
a single buffer so that only a single file descriptor is required per
IPC transfer, even if multiple frames are being sent.
Previously, if you ran with a relative path, then everything would run
fine except that the test name would be blank in the output, eg:
1/1234:
instead of:
1/1234: Text/input/canvas/export.html
Multiple font properties are either the `normal` keyword or some
non-keyword value, so this lets us avoid some boilerplate for those, at
the cost of the existing `none` users having marginally more verbose
code.
This is a special form of `<string>` so doesn't need its own style value
type. It's used in a couple of font-related properties. For completeness
it's included in ValueType.
