`Optional` and `Variant` both use essentially the same pattern of only
declaring a copy constructor/move constructor/destructor and copy/move
assignment operator if all of their template parameters have one.
Let's move these into a macro to avoid code duplication and to give a
name to the thing we are trying to accomplish.
Stealing the callbacks from the AnimationFrameCallbackDriver made them
no longer safe from GC. Continue to store them on the class until we
have finished their execution.
Better support for CSS shorthands when setting the style attribute. This
improves some tests in WPT /css/css-align/default-alignment/*shorthand.
When setting the style attribute in JS via element.style = '..' or the
setAttribute method, shorthand properties were not expanded to longhand
properties.
The DOM spec gets overridden by both the SVG2 and MathML core specs in
that unknown elements should not inherit DOM::Element, but
SVG::SVGElement and MathML::MathMLElement respectively.
This is a mixin in the IDL, so let's treat it as a mixin in our code and
let both SVGElement and MathMLElement reuse the implementations that we
wrote for HTMLElement.
This change helps to ensure issue authors include the details needed to
reproduce problems — including repro steps, expected behavior, a reduced
test case, and logs/backtrace.
Previously, attempting to parse a floating point number with an integer
part larger than `(2 ^ 31) - 1` would cause the browser to crash. We now
avoid this by converting the integer part of the number to a `double`
rather than an `i32`.
This change makes the Meta/import-wpt-test.py script handle URLs such as
https://wpt.live//WebCryptoAPI/generateKey/../util/helpers.js and paths
containing, e.g., wpt-import/WebCryptoAPI/generateKey/../util/helpers.js
(that is, URLs and paths with “..” parent-directory references in them).
Otherwise, without this change, when the import-wpt-test.py script tries
a URL like https://wpt.live//WebCryptoAPI/generateKey/../util/helpers.js
which contains a “..” parent-directory reference, the script fails with
a “urllib.error.HTTPError: HTTP Error 404: Not Found” error message.
This avoids needing to creating root handles for each heap-allocated
object captured in the animation callback. An upcoming commit would add
several of these.
Fixes wpt/png/exif-chunk.html.
At some point there should probably be some mechanism to handle this
outside of the individual decoder plugins. The TIFF decoder seems to
have its own version of this, and as far as I can tell, the JPEG decoder
doesn't handle this at all, even though that's probably the most common
use case for Exif orientations. :^)
This change imports the WPT accname/name/comp_embedded_control.html
test, along with related resources files it depends on.
Note that in the wai-aria/scripts/aria-utils.js file, this changes the
get_computed_label call to use our window.internals.getComputedLabel.
This change implements the “C: Embedded Control” step at
https://w3c.github.io/accname/#step2C in the “Accessible Name and
Description Computation” spec — to compute the accessible names for
labeled form controls.
Similar to commit a9c858fc78, this patch
implements the WebDriver spec concept of shadow references grouped
according to their browsing context groups.
We currently spin the event loop to wait for the specified element to
become available. As we've seen with other endpoints, this can result
in dead locks if another web component also spins the event loop.
This patch makes the locator implementations asynchronous.
