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.
Two font properties, font-feature-settings and font-variation-settings,
contain a list of values that are an `<opentype-tag>` followed by a
single value. This class is intended to fill both roles.
StyleComputer is responsible for assigning animation targets, so we
have to make sure there are no pending style updates before querying
animations of an element.
This change also introduces a version of getAnimations() that does not
check style updates and used by StyleComputer to avoid mutual recursion.
The HTML tokenizer specification says that we're supposed to do this
when leaving the Attribute name or when emitting the token, as
appropriate.
Hopefully 'as appropriate' can mean only when emitting the token, as
that's the easiest place to insert this logic without complicating the
tokenizer any more.
Similar to script execution, this spins the WebDriver process until the
action is complete (rather than spinning the WebContent process, which
we've seen result in deadlocks).
This implements execution of the pointer up, pointer down, and pointer
move actions.
This isn't 100% complete. Pointer move actions are supposed to break
the move into iterations over the specified duration, which we currently
do not do.
In particular, we need to convert web element references to the actual
element. The AO isn't fully implemented because we will need to work out
mixing JsonValue types with JS value types, which currently isn't very
straight forward with our JSON clone algorithm.
This is only used for finding font directories for now, but having a
convenient function for it means if anyone needs to use XDG_DATA_DIRS
in future, they're less likely to implement it themselves and miss the
case of it being present but empty.
We also now canonicalize the data directory paths, as we do for the
other standard paths.
The XDG spec repeatedly says, for example:
> If $XDG_DATA_HOME is either not set or empty, a default equal to
$HOME/.local/share should be used.
- https://specifications.freedesktop.org/basedir-spec/latest/index.html
It's rare in practice, but does happen, for example in #1507 where we
would fail to find any system fonts if `XDG_DATA_DIRS` was blank.
This code now treats whitespace-only variables as empty too, which may
be overkill, but seems better to me than not doing so.
We had numerous NiH-based implementations of audio formats and metadata
that we now no longer need because we either don't make use of the code,
or we replaced its implementation by FFmpeg.
This loader supports whatever format libavformat and libavcodec can
handle. Currently only seekable streams are supported, and we still have
some limitations as to the number of channels and sample format.
