This is the base class for all SVG gradient types. This supports:
- The `gradientUnits` attribute
- The `gradientTransform` attribute
- And following `xlink:hrefs` for inheriting <stops>/attributes
This will be needed to access the color of a stop from a SVG gradient
<stop> element (which does not participate in layout, so does not have
a layout node).
I found this handy for debugging, and so might others.
This now also adds a formatter for TimeZone::TimeZone. This is needed
for FormatIfSupported<Optional<TimeZone::TimeZone>> to compile. As
FormatIfSupported sees a formatter for Optional exists, but not that
there's not one for TimeZone::TimeZone.
Process created performance events for kernel processes are only ever
emitted for the kernel processes that exist when profiling is enabled.
Any new kernel processes created after profiling is enabled will not
have corresponding process created performance events, so all kernel
processes should be created before enabling profiling.
NetworkTask was the only kernel process being created after enabling
profiling, so we now just create it before enabling profiling. This
fixes an issue where Profiler was failing to parse boot profiles as a
result of NetworkTask not having a process created event.
The new baked image is a Prekernel and a Kernel baked together now, so
essentially we no longer need to pass the Prekernel as -kernel and the
actual kernel image as -initrd to QEMU, leaving the option to pass an
actual initrd or initramfs module later on with multiboot.
Previously, the minimum height of a table row was calculated based
on the automatic height of the cells inner layout. This change makes
computed height of a cell boxes also be considered if it has definite
value.
While swap() is available in the global namespace in normal conditions,
!USING_AK_GLOBALLY will make this name unavailable in the global
namespace, making these calls fail to compile.
That pattern seems to show up a lot in code written by people that
aren't intimately familiar with the lifetime model of Error and Strings.
This commit makes the compiler detect it and present a more helpful
diagnostic than "garbage string at runtime".
When deciding on a box type transformation (blockify/inlinify) for a
pseudo element, we have to use the originating element as a reference
rather than the parent.
(The originating element *is* the parent for its pseudo elements.)
This can occur if a mouse click on a mouse event tracking node causes a
page navigation. As the old document is torn down, the event handler may
have a stale reference to the tracking node. If a subsequent mouse event
occurs on that node, we would crash trying to access the node's styled
properties that are no longer valid.
To fix this, when we are deciding what node to send the event to, and we
have a mouse event tracking node, check if that node still wants the
event. If not, clear the tracking node.
For example, it's possible to access Node::computed_values() on a node
that neither has style nor a parent with style. This ultimately results
in a null pointer dereference when we return parent()->computed_values()
as a fallback. This can be a little tricky to track down due to these
functions being inlined, so add an explicit verification.
We fail to build `getconf.c` from the builtin examples. And therefore
don't install the rest. If we remove it, we successfully build the
rest of the examples.
If there is a remaining margin-bottom in margin collapsing state
tracker after laying out all boxes in the current BFC, it must be
assigned to the last in-flow child since margin collapsing cannot
occur across a formatting context boundary.
The current issue where margin-bottom may be counted twice due to
"collapse through" margins in the last in-flow child box is addressed
with this fix by excluding such boxes during the search for a box to
assign the remaining margin.
Test case coming with this fix has a layout bug with incorrectly
computed line height.
The WebContent process behaves a bit awkwardly on macOS. When we launch
the process, we have to create a QGuiApplication to access system fonts.
But on macOS, doing so creates an entry in the Dock, and also causes the
WebContent to be focused. So if you enter cmd+Q without first focusing
the Ladybird GUI, WebContent is closed, while the Ladybird process keeps
running.
