Implements the same optimization we already have for DrawGlyphRun by
saving unscaled glyph run and scale factor in a painting command, which
allows to avoid copying of glyphs vector to apply scaling during
recording.
We currently build debug and release versions of vcpkg dependencies. We
will most commonly only need the release version, so let's default to
that to approximately halve our dependency build time.
By moving this up to ConnectionBase, we have less custom code for each
templated subclass, and it gets a little easier to edit the code since
you don't have to rebuild as much when making changes.
If Metal context and IOSurface are available, Skia painter will use
Ganesh GPU backend on macOS, which is noticeably faster than the default
CPU backend.
Painting pipeline:
1. (WebContent) Allocate IOSurface for backing store
2. (WebContent) Allocate MTLTexture that wraps IOSurface
3. (WebContent) Paint into MTLTexture using Skia
4. (Browser) Wrap IOSurface into Gfx::Painter and use
QPainter/CoreGraphics to blit backing store into viewport.
Things we should improve in the future:
1. Upload textures for images in advance instead of doing that before
every repaint.
2. Teach AppKit client to read directly from IOSurface instead of
copying.
In the upcoming changes, Skia painter will be switched to Metal backend,
so we can no longer assume `pitch = width * 4` while reading Gfx::Bitmap
that wraps IOSurface populated by writing into MTLTexture that has
padded scanlines.
Previously, autocomplete was cleared before the results for the current
query were retrieved. The new results would then be added when the
network request completed. This resulted in a noticable flicker. The
results are now updated when the request for the current query is
completed.
There is a small behavior change in that the query itself is no longer
included in the autocomplete dropdown unless the list would otherwise
be empty.
This is a non-standard API that other browsers implement, which
highlights matching text in the current window.
This is just a thin wrapper around our find in page functionality, the
main motivation for adding this API is that it allows us to write tests
for our find in page implementation.
This was only put in place because on SerenityOS, we wanted to use the
pid of the WebContent process, rather than the peer pid for the socket.
When launching with SystemServer, this got annoying. However, now that
we only have the case that the UI process spawns processes, we can
get rid of this hack. This restores the ability to see WebContent
processes' statistics in the task manager widget.
This is the same behavior as RequestServer, with the added benefit that
we know how to gracefully reconnect ImageDecoder to all WebContent
processes on restart.
This is mostly useful when some application-level logic needs to
iterate over all child processes. A more robust Process abstraction
would make this easier.
They are now blocked on pages which:
- Don't have an opaque origin (should be only user-initiated or about:)
- Aren't other file: pages
- Aren't other resource: pages
The `deepEquals` algorithm used for testing was naive, and incorrectly
evaluated equality of objects in some cases. The new algorithm considers
that the second object could have more keys than the first, and compares
the prototypes of the objects.
An input event is now fired when the step up or step down button of an
input element of type number is clicked.
This ensures that any associated <output> element is updated when these
buttons are clicked.
Input elements without a defined user-interaction behavior need to fire
an input event when the user changes the element's value in some way.
This change moves the code to do this into its own function and adds
some spec text to explain what is being done.
The changes to tests are due to LibTimeZone incorrectly interpreting
time stamps in the TZDB. The TZDB will list zone transitions in either
UTC or the zone's local time (which is then subject to DST offsets).
LibTimeZone did not handle the latter at all.
For example:
The following rule is in effect until November 18, 6PM UTC.
America/Chicago -5:50:36 - LMT 1883 Nov 18 18:00u
The following rule is in effect until March 1, 2AM in Chicago time. But
at that time, a DST transition occurs, so the local time is actually
3AM.
America/Chicago -6:00 Chicago C%sT 1936 Mar 1 2:00
This required updating some LibJS spec steps to their latest versions,
as the data expected by the old steps does not quite match the APIs that
are available with the ICU. The new spec steps are much more aligned.
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
Prior to this commit, the test runner was ignoring the result, which
meant that values that fit in less than 128 bits were shifted to remove
the zero words (which is obviously incorrect).
