These steps run when a node is about to be removed from its parent,
and adjust the position of any live NodeIterators so that they don't
point at a now-removed node.
Note that while this commit implements what's in the DOM specification,
the specification doesn't fully match what other browsers do.
Spec bug: https://github.com/whatwg/dom/issues/907
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.
Other engines don't give NaN if there is at least one digit after the
dot for milliseconds. We were much stricter and required exactly three
digits.
But there is real world usage of different amounts of digits such as
discord having three extra trailing zeros.
These fences should not be needed, since we force the use of
synchronous operations through synchronous_virtio_gpu_command. The use
of these fences also causes severe lag when SERENITY_GL is enabled.
This commit flips VirtIOGPU back to using a Mutex for its operation
lock (instead of a spinlock). This is necessary for avoiding a few
system hangs when queuing actions on the driver from multiple
processes, which becomes much more of an issue when using VirGL from
multiple userspace process.
This does result in a few code paths where we inevitably have to grab
a mutex from inside a spinlock, the only way to fix both issues is to
move to issuing asynchronous virtio gpu commands.

The project appears to build just fine without it, and the explicit use
of `LibC` causes it to conflict with the system-wide `fd_set.h` when
building inside of Serenity.
This additionally refactors FramebufferDevice::try_to_initialize to not
leave the FramebufferDevice in an invalid state on errors.
This also unifies the logic between FramebufferDevice::mmap and
FramebufferDevice::try_to_initialize.
This comes with the drawback of removing the UNMAP_AFTER_INIT attribute
from this function, which wasn't honoured by IntelNativeGraphicsAdapter
anyway.
Since the selection already gets updated in AbstractView::keydown_event
and AbstractView::mousedown_event we don't have to update it again in
the MainWidget::open_url function.
This fixes a bug that causes the selection to "spaz out" when
scrolling too fast between pages.
Moves the nix script to setup the build environment from Documentation
into the Toolchain as a callable script. I also modified the script
to accept a "pkgs" argument to make it easy to override the nixpkgs
version from the command-line when calling the script.
If init crashes, all other userspace processes exit too, thus rendering
the system unusable. Previously, the kernel would still keep running
even without a userland, showing just a black screen without any
indication of the issue.
We now panic the kernel, which shows a message on the console. In the
case of the CI runners, it shuts down the virtual machine, so we don't
have to wait for the 1 hour timeout if an issue arises with
SystemServer.
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.
The config.guess file needs to know about the SerenityOS `uname -m`
system name if we want to build ports inside Serenity. Support was only
added in January 2022, so most ports don't have a new enough version
yet.
This commit adds facilities for fetching a fresh config.guess file that
supports SerenityOS, similarly to what we do for config.sub. As its
first user, we make the bash port buildable inside the system.
We don't have a perl port, so let's use GNU sed's in-place option for
doing substitutions when running inside Serenity.
Note that we can't do this unconditionally, as `sed -i` is not portable
and works differently on BSD systems.
Previously we would fail to generate any hunks if the old or the new
file was empty. We now do, with the original/target line index set to 0,
as specified by POSIX.
