Now that we support audio, we can start correctly reporting we support
certain audio mime types!
Required by certain sites like Gartic Phone, which fails to load audio
because we didn't return a non-empty string for `audio/mpeg`:
```
"https://garticphone.com/sounds/turnundefined", Error: Load failed: 404
```
```js
(new Audio).canPlayType("audio/mpeg") && (this._extension = ".mp3"),
```
The transform can change between path building operations (and before
the path is filled or stroked). This fixes the sun ray backgroun on
the https://www.kevs3d.co.uk/dev/html5logo/ canvas demo.
The audio element behaves a bit differently than the video element in
that the audio element drives itself on a timer (as opposed to LibVideo
notifying the video element when a frame is available). So if an audio
element is paused while seeking, we wouldn't receive an updated playback
position until the element is unpaused.
This fixes an issue where you would have to click the play button twice
to re-start an audio track after it reached the end.
It can take some time to download / decode a media resource. During this
time, its duration is set to NaN. The media control box would then have
some odd rendering glitches as it tried to treat NaN as an actual time.
Once we do have a duration, we also must ensure the media control box is
updated.
As it turns out, making everyone piggyback on HTML::ImageRequest had
some major flaws, as HTMLImageElement may decide to abort an ongoing
fetch or wipe out image data, even when someone else is using the same
image request.
To avoid this issue, this patch introduces SharedImageRequest, and then
implements ImageRequest on top of that.
Other clients of the ImageRequest API are moved to SharedImageRequest
as well, and ImageRequest is now only used by HTMLImageElement.
This fixes an issue with image data disappearing and leading to asserts
and/or visually absent images.
This moves the painting of the media timeout out of VideoPaintable into
a base MediaPaintable. This is to allow re-using the same timeline logic
and controls for audio elements.
Although DistinctNumeric, which is supposed to abstract the underlying
type, was used to represent CSSPixels, we have a whole bunch of places
in the layout code that assume CSSPixels::value() returns a
floating-point type. This assumption makes it difficult to replace the
underlying type in CSSPixels with a non-floating type.
To make it easier to transition CSSPixels to fixed-point math, one step
we can take is to prevent access to the underlying type using value()
and instead use explicit conversions with the to_float(), to_double(),
and to_int() methods.
Like the piggybacking in CSS, this is also totally ad-hoc, since there's
no spec to follow.
The code here is weird and definitely sub-optimal as we do a second load
if it turns out the loaded resource is an image, but given that object
elements are rarely used nowadays, I doubt we'll even notice.
That said, we should of course improve this code as we move forward.
This forces us to diverge from the spec, but it's for a good cause:
by moving it into ImageRequest, we'll be able to reuse fetching and
decoding logic from CSS and other places.
This patch also makes ImageRequests shareable, currently keyed by
the URL (this part needs improvement!)
To abort the processing of any nested invocations of the tokenizer,
just return is enough in this case.
During the process of pending parsing blocking script, the
is_ready_to_be_parser_executed() check should be applied on the
blocking script, not the original script.
Now that the processResponseConsumeBody algorithm receives the internal
response body of the fetched object, we do not need to go out of our way
to read its body from outside of fetch.
However, several elements do still need to manually inspect the internal
response for other data, such as response headers and status. Note that
HTMLScriptElement already does the new workaround as a proper spec step.
This allows us to figure out where a specific CSS property comes from,
which is going to be used in a future commit to uniquely identify
running animations.
We have to check that the entry in CrossOriginProperties is the one
actually requested from the caller before executing the body of the
loop. This fixes a crash triggered by YouTube iframe embedding.
Instead of eagerly populating the stack trace with a textual
representation of every call frame, just store the raw source code range
(code, start offset, end offset). From that, we can generate the full
rich backtrace when requested, and save ourselves the trouble otherwise.
This makes test-wasm take ~7 seconds on my machine instead of ~60. :^)
This PR corrects the signs of the start/end points that are passed
to the elliptical_arc_to(), it also removes the bogus path.close()
after creating the arc. Now .arc() seems to work correctly.
