This patch adds CSS::property_affects_layout(PropertyID) which tells us
whether a CSS property would affect layout if it were changed.
This will be used to avoid unnecessary relayout work when something
changes that really only requires us to repaint the page.
To mark a property as not affecting layout, set "affects-layout" to
false in the corresponding Properties.json entry. Note that all
properties affect layout by default.
...and let LibWasm do the validation instead of removing the test when a
module is invalid.
Also, one of the tests has an integer literal starting with zero, so
account for this to make it not fail :^)
Since we want to store an initial value for every CSS::PropertyID,
it's pretty silly to use a HashMap when we can use an Array.
This takes the function from ~2.8% when mousing around on GitHub all the
way down to ~0.6%. :^)
As there is no need for a Prekernel on aarch64, the Prekernel code was
moved into Kernel itself. The functionality remains the same.
SERENITY_KERNEL_AND_INITRD in run.sh specifies a kernel and an inital
ramdisk to be used by the emulator. This is needed because aarch64
does not need a Prekernel and the other ones do.
These work differently from how we validate StyleValues. There, we parse
a StyleValue from the CSS, and then see if it is allowed in the
property. That causes problems when the syntax is ambiguous - for
example, `0` can be a number or a Length.
Here instead, we ask what kinds of value are allowed for a
media-feature, and then only attempt to parse those kinds of value.
This makes the ambiguity problem go away. :^)
Each media-feature in the spec only accepts one type of value, and/or
some identifiers. This makes the switch statements for the type a bit
excessive, but the spec does not *require* that only one type is
allowed, so this is more future-proof.
This works largely the same as the PropertyID and ValueID generators,
but using LibMain, Core::Stream, and TRY().
Rather than have a MediaFeatureID::Invalid, I decided to return an
Optional. We'll see if that turns out better or not. :^)
This patch adds NodeIterator (created via Document.createNodeIterator())
which allows you to iterate through all the nodes in a subtree while
filtering with a provided NodeFilter callback along the way.
This first cut implements the full API, but does not yet handle nodes
being removed from the document while referenced by the iterator. That
will be done in a subsequent patch.
This directory has to be writable if we want to install ports that have
been built inside Serenity. It's owned by root anyway, so having it be
read-only does not provide many security benefits.
Because of ninja's default behavior of using all processors this gave
the correct behaviour because MAKEJOBS was empty. However this meant
that the processor count was printed to stderr when building.
This initial version lays down the basic foundation of IDL overload
resolution, but much of it will have to be replaced with the actual IDL
overload resolution algorithms once we start implementing more complex
IDL overloading scenarios.
The microvm machine type is a modern tool for kernel and firmware
developers to test their software against features like FDTs, second
IOAPIC, lack of legacy devices by default, the ability of using PCIe
without using PCI x86 IO ports, etc.
We can boot into such machine but we are limited in the functionality we
support currently for this type of virtual machine.
The ISA-PC machine type provides no PCI bus support, no IOAPIC support
and other modern PC features of our generation.
This is mainly a good environment for testing abstractions in the kernel
space, and can help with improving on them for the sake of porting the
OS to other chipsets and CPU architectures.
We use the environment variable SERENITY_SOURCE_DIR to resolve and check
icon links. This is a bit inconvenient as SERENITY_SOURCE_DIR needs to
be set correctly before invoking the markdown checker, but as we use it
through the check-markdown script anyways, I think it's not a problem.
Previously we added it only if spice was available, but it's possible to
build qemu with --disable-spice --enable-spice-protocol, which provides
qemu-vdagent but no spicevmc. In such case we still configured
qemu-vdagent to use "vdagent" device, but never actually defined it, so
the qemu-vdagent was never working.
This allows us to fuzz the generated unicode and timezone database
helpers, and to fuzz things like LibJS using Fuzzilli to get proper
coverage of our unicode handling code.
Update the Azure CI to use the new two-stage build as well, and cleanup
some unused CMake options there.
According to its manpage genext2fs tries to create the file system with
as few inodes as possible. This causes SerenityOS to fail at boot time
when creating temporary files.
We now pass along the toolchain type to all subcommands. This ensures
that gdb will load the correct debug information for kernels compiled
with Clang, and the following warning won't appear with the GNU
toolchain:
> WARNING: unknown toolchain 'gdb'. Defaulting to GNU.
> Valid values are 'Clang', 'GNU' (default)
WebSockets got moved from the HTML standard to their own, the new
WebSockets Standard (https://websockets.spec.whatwg.org).
Move the IDL file and implementation into a new WebSockets directory and
C++ namespace accordingly.
