These are similar to prototypes and constructors in that they will now
be lazily instantiated when they are first requested.
|
|
For example, the CSS namespace is defined via IDL, but we currently have
a manual implementation.
|
|
Rather than creating a TextStyle struct, and then copying its fields
over to a TextAttributes, let's just create a TextAttributes to start
with. This also simplifies the syntax highlighting code by letting us
define underlines along with the other text styling.
|
|
Rather than having a style AND a field saying whether to use the style,
just make the style Optional.

This has no effect in practice: decode_bmp_v5_dib() is the last
thing called with the streamer object (...the streamer is passed
to set_dib_bitmasks(), but that doesn't read anything off it except
for DIBType::Info bitmaps, which v5 bitmaps aren't).
But dib_size is 16 larger for v5 than for v4, so we should read
16 bytes.
This is also useful for a hypothetical person who might look at
the reading code to figure out how the writing code should look like.

It's always 4 bytes, so the data fits in a String's inline buffer.
(Else I would've used a StringView.)

This method added function using host byte order, which is never what we
want.
In practice, it was fine because it was only called from add_u8()
(which is just 1 byte large) and add_as_big_endian() (since that did
endian swapping before calling the method). But the method doesn't
really help any and is dangerous, so remove it.
No behavior change.
|
|
PNG uses big-endian data internally.

This probably does strange things for CMYK jpegs, since JPEGLoader
converts those from CMYK to RGB but the ICC profile is still an CMYK
profile. The Right Fix for that is probably for JPEGLoader to consume
the profile when it does CMYK->RGB conversion and then not hand out
the profile data. (Or we could add a CMYK bitmap type.)
But most of the time, this is a progression :^)

This will help us catch any future regressions immediately.

This fixes an issue where fonts would often paint at the wrong sizes
with device pixel ratios other than 1.0.
|
|
This returns the font size in pt instead of px.

These were somewhat found by trial and error, but it seems like this
is now the required set to launch this without error.
|
|
This ensures we only need to download these files once for all build
configurations. We similarly download the UCD, CLDR, and TZDB to this
cache directory as well.
|
|
Use the same pattern for Ramdisk similar to other storage devices during
device initialization. This will propagate errors if the Ramdisk fails
to initialize.
|
|
Storage controllers are initialized during init and are never modified.
NonnullRefPtr can be safely used instead of the NonnullLockRefPtr. This
also fixes one of the UB issue that was there when using an NVMe device
because of NonnullLockRefPtr.
We can add proper locking when we need to modify the storage controllers
after init.

Now it is called `CaseInsensitiveASCIIStringViewTraits`, so we can be
more specific about what data structure does it operate onto. ;)
|
|
|
|
For example, consider the attribute:
interface Element {
[PutForwards=value] readonly attribute DOMTokenList classList;
}
When `classList` is set, we should instead set the attribute `value` on
the `classList` attribute of the Element interface.

It is not sufficient to just invalidate layout when a new font has
loaded, because while it was loading we might have chosen a fallback
font-family value instead.
Invalidate style instead.

The image made the test flaky when running on my machine, so this
doesn't seem safe at the moment. We can just hardcode the dimensions.
Eventually we should make it possible to use external images in tests,
but for now let's not flake up the CI.

Thanks to Luke for noticing the issue on YouTube! :^)

Don't try to reserve capacity for a variadic arguments list unless we
actually have enough arguments to fill it with anything. Otherwise we
may overflow to an extremely large size if, e.g., the argument count
is 0 and the start of the variadic arguments is index 1.
|
|
Before this patch, we would build full computed style for these pseudo
elements, for every DOM element, even if no ::before/::after selector
actually matched.
This was a colossal waste of time, and we can also just not do that.
Instead, just abort pseudo element style resolution early if no relevant
selectors matched. :^)

This can avoid getting into a situation where lots of MouseMove events
are queued up and they all trigger relayout (or something else that
takes a lot of time).
To make sure that we don't get out of sync with the input events queue
on the UI process side, we still send acknowledgements for coalesced
MouseMoves. There's room for improvement here.
My Discord friends list is now pleasantly responsive. :^)
|
|
We already had head(), so let's also have tail().
|
|
Before this patch, we had an issue where the WebContent process could
get backed up with tons of pending input events (especially mouse moves)
and have to work through all of those before responding to a paint
request from the UI process.
This could lead to a situation where we went for a very long time
without seeing any visual updates.
The approach I've taken here is pretty simple, we basically make a queue
of all incoming input events on the WebContent process side, and then
process that queue one event at a time, using a zero timer. This is
basic, but it allows paint requests to come in between the input events
and we do now get more frequent visual updates even during heavy
pressure from input events.

When we're calculating the intrinsic size of a flex container, we don't
*need* to layout the inside of each flex item. That's only necessary if
the flex items will be seen (as is the case for "normal" layout).
This avoids a whole bunch of unnecessary layout work on pages that use
flexbox layout. :^)
|
|
This patch replaces the usage of QPalette::PlaceholderText with
QPalette::Text with opacity reduced to roughly 50%. This fixes the non
highlighted spans having an extremely low contrast compared to the
background in dark mode.

According to CSS Inline Layout Module Level 3 ยง 2.2 Step 1. atomic
inlines should be layed out in a line box based on their margin box.
However, up until this patch we were unconditionally considering only
the border box during line box height calculation. This made us
essentially drop all vertical margins for atomic inlines.
