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.
This is the IPv6 counter part to the IPv4Address class and implements
parsing strings into a in6_addr and formatting one as a string. It
supports the address compression scheme as well as IPv4 mapped
addresses.
When the initialization statement of a for-loop uses 'let', we must
create a new environment for each iteration of the for loop. The
bindings of the initialization statement are copied over to the new
environment. Since the bindings are created in the same order each time,
we can use that order to directly initialize the bindings and avoid any
O(n) lookups in this hot loop.
Similar to the direct getter and setter in DeclarativeEnvironment, there
are cases where we already know the index of a binding and can avoid a
O(n) lookup to re-find that index.
This reduces the size of the DeclarativeEnvironment from 72 bytes to 48
bytes. This savings helps in the context of nested for-loops which use
'let' to bind the initial variable declarations. In this case, the spec
dicates we create a new environment for each loop iteration by way of
the CreatePerIterationEnvironment AO.
In particular, test262's generated RegExp tests contains many loops of
the form:
for (let i = 0; i < a_number_on_the_order_of_10; ++i)
for (let j = 0; j < a_number_on_the_order_of_10_thousand; ++j)
This results in creating hundreds of thousands of environments.
Currently we have a 'Project' menu with a 'New' menu in it, this tries
to organize things by just having one 'New...' sub-menu in the 'File'
menu that creates new files, projects and directories.
To solve conflicts, move 'Semantic Highlighting' to the 'View' menu.
As a result of both of these changes, remove 'Project' menu.
The local file header signature of a ZIP entry is normally 0x04034B50
and stored in little-endian byte order. Therefore, if the archive
starts with an entry we can identify a ZIP file by checking if the
first two bytes are 0x504B (PK).
Also checks for the .zip file extension, which is is also used by file
if no byte signature was detected.
NumericCell::display() attempted to take a substring of cell contents
according to the "Override max length" parameter,
but it did not account for the actual string length.
