When testing the RTL8168 driver, it seems we can't allocate super pages
anymore. Either we expand the super pages range, or find a solution to
dynamically expand the range (or let drivers utilize other ranges).
We previously stored the Window object in a global RefPtr (for no
apparent reason).
This led to a use-after-free bug in the Window's destructor when
HackStudio was exited via the Quit action (Exiting by closing the
window did not trigger this bug).
This is a hack, but it seems to do quite okay.
What we should do is to find the largest size the Box could want in its
main axis. To do that we have to layout the Box according to the needed
LayoutMode. For flex-rows we do as requested and try to make the Box as
wide as we want.
However, for flex-columns we simply assume the Box is a Block and we
calculate their height according to this.
We don't want to destroy the WebSocketImpl while we're still using it
higher up the stack. By using deferred_invoke(), we allow the stack
to unwind before actually destroying any objects.
This fixes an issue with the WebSocket service crashing on immediate
connection failure.
Resize the clipboard history size dynamically by listening for config
changes. This is currently not ideal since we don't have the callbacks
for `Config::Listener::config_i32_did_change`, so for now we are just
taking the string and attempting to convert it to an int.
The number of items in history was hardcoded to 20 earlier, now
we try to load this value from a config file. The default if none
is available is still 20.
If we hit an assertion while the heap isn't in a stable state, we can't
rely on dynamic memory allocation because the malloc mutex is already
held and the heap is most likely corrupted. Instead, we need to bail
out fast before we make the situation even worse.
Instead of trying to layout SVG boxes as if they are regular CSS boxes,
let's invent an "SVG formatting context" and let it manage SVG boxes.
To facilitate this, Layout::SVGBox no longer inherits from ReplacedBox,
and is instead a simple, "inline-block" style BlockBox.
The POSIX manpage just says that wctrans_t should be "a scalar type that
can hold values which represent locale-specific character mappings", and
doing switch statements with ints is much more pleasant than with
pointers.
If our parent in the FlexFormattingContext also was a flex-container, we
didn't give our children any meaningful width to play with into
layout_inside(), which resulted in way too narrow layouting.
Now the width of the parent gets borrowed if the own width isn't
specified.
The previous VERIFY_NOT_REACHED() could be reached when there were equal
coodinates. This could be the case for a small radius which lead to
rounding making the two coordinates equal.
This adds an option for even more magnification, when you really need to
count pixels, as well as pausing the capture by pressing Space and
switching between magnification levels with keys 2, 4 & 8.
This now uses the values in `InitialValues`, which is not ideal, but
it's better to have our defaults defined in two places, than in 3.
The default for `border-colors` is `currentcolor`, so we shortcut that
here and just grab the value of the `color` property. As noted, this is
not perfect, but it's somewhat better.
- The `text-decoration-foo` values now match the spec.
- Added values for `border-foo` since those are needed soon.
- Make `color`'s initial value be `-libweb-palette-base-text`.
When parsing shorthand values, we'd like to use
`property_initial_value()` to get their longhand property values,
instead of hard-coding them as we currently do. That involves
recursively calling that function while the `initial_values` map is
being initialized, which causes problems because the shorthands appear
alphabetically before their longhand components, so the longhands aren't
initialized yet!
The solution here is to perform 2 passes when generating the code,
outputting properties without "longhands" first, and the rest after.
This could potentially cause issues when shorthands have multiple
levels, in particular `border` -> `border-color` -> `border-left-color`.
But, we do not currently define a default value for `border`, and
`border-color` takes only a single value, so it's fine for now. :^)
