In the spec, this happens in the EvaluateCall abstract operation
(https://tc39.es/ecma262/#sec-evaluatecall), and the order is defined
as:
3. Let argList be ? ArgumentListEvaluation of arguments.
4. If Type(func) is not Object, throw a TypeError exception.
5. If IsCallable(func) is false, throw a TypeError exception.
In LibJS this is handled by CallExpression::execute(), which had the
callee function check first and would therefore never evaluate the
arguments for a non-function callee.
This is just to make the CSS parser stop whining when it encounters some
very common properties and identifiers. More work will be required to
actually support these things. :^)
Since we don't have a direct connection to WindowServer, this is slighly
more naive implementation than what we were doing for single-process
mode.
Basically, there's a global RequestAnimationFrameDriver object that
has a 16ms single-shot timer. Whenever someone registers for a RAF
callback, we start the timer (if needed).
This is not ideal, but it's better than nothing. :^)
This is a very partial implementation, as some features (like 2 of the
possible constructor types, iteration and the getAll method) are
missing, and other's are not implemented due to the currently missing
URL built-in.
This namespace will be used for all interfaces defined in the URL
specification, like URL and URLSearchParams.
This has the unfortunate side-effect of requiring us to use the fully
qualified AK::URL name whenever we want to refer to the AK class, so
this commit also fixes all such references.
...instead of relying on the VM having a current execution context. This
was an incorrect assumption I made, and it caused onfoo attribute
handler construction in LibWeb to crash.
Just use the same mechanism as NativeFunction in the meantime.
ConditionVariable is a thin wrapper over the pthread_cond_* APIs, just
as Mutex is a wrapper over pthread_mutex.
Because ConditionVariable might want to wait on a high-level Mutex, it
needs to be friends with it.
Across the entire audio system, audio now works in 0-1 terms instead of
0-100 as before. Therefore, volume is now a double instead of an int.
The master volume of the AudioServer changes smoothly through a
FadingProperty, preventing clicks. Finally, volume computations are done
with logarithmic scaling, which is more natural for the human ear.
Note that this could be 4-5 different commits, but as they change each
other's code all the time, it makes no sense to split them up.
For example, this CSS previously produced a lot of log spam about the
`display` properties having invalid values:
```css
.foo {
display: -webkit-box;
display: -moz-box;
display: -ms-flexbox;
display: -webkit-flex;
display: flex;
}
```
Now, it just ignores them, because we don't need to know about it. :^)
Our debug logging when we fail to parse a legitimate selector, is less
useful when it's hidden among selectors that don't parse because they
contain vendor-prefixed pseudo-elements and classes. So, now we
specifically ignore these and don't produce a log message.
When a file deletion event happens, we now iterate over all views of the
FileSystemModel and remove any selection & cursor indices that hold
dangling references do the deleted filesystem node.
This fixes#9602.
getComputedStyle(element) now returns a ComputedCSSStyleDeclaration
object, which is a live view of the computed style of a given element.
This works by ComputedCSSStyleDeclaration being a wrapper around an
element pointer. When you ask it for a CSS property, it gets the latest
computed style values from the element and returns them as a
CSS::StyleProperty object.
This first cut adds support for computed 'color' and 'display'.
In case the element doesn't have a corresponding node in the layout
tree, we fall back to using specified style instead. This is achieved by
performing an on-the-fly style resolution for the individual element and
then grabbing the requested property from that resolved style.
This patch moves the CSS property+value storage down to a new subclass
of CSSStyleDeclaration called PropertyOwningCSSStyleDeclaration.
The JavaScript wrapper for CSSStyleDeclaration now calls virtual
functions on the C++ object.
This is preparation for supporting computed style CSSStyleDeclaration
objects which won't have internal property storage, but rather an
internal element pointer. :^)
Prior this change, the button was updated on user selection change
in the file view.
This isn't quite right, as you could remove the text from the text box
or (even worse) start typing a filename there and the button state
wouldn't change.
When debugging why your website isn't loading in LibWeb the
resource loader is a blind spot as we don't have much logging
except on certain error paths. This can lead to confusing situations
where the browser just appears to hang.
This changes attempts to fix that by adding common success and
failure logging handlers so all resource loading outcomes can
are logged.
