This subdirectory is meant to hold all constant data related to the
kernel. This means that this data is never meant to updated and is
relevant from system boot to system shutdown.
Move the inodes of "load_base", "cmdline" and "system_mode" to that
directory. All nodes under this new subdirectory are generated during
boot, and therefore don't require calling kmalloc each time we need to
read them. Locking is also not necessary, because these nodes and their
data are completely static once being generated.

I just got bit by this type of bug in a different project, and was
wondering whether Serenity has this problem, too. See also:

Currently when trying to use the right-shift on the pt-br layout
it prints a "?" on key-down on top of applying the shift modifier.
This patch removes the unwanted "?".
This filesystem is based on the code of the long-lived TmpFS. It differs
from that filesystem in one keypoint - its root inode doesn't have a
sticky bit on it.
Therefore, we mount it on /dev, to ensure only root can modify files on
that directory. In addition to that, /tmp is mounted directly in the
SystemServer main (start) code, so it's no longer specified in the fstab
file. We ensure that /tmp has a sticky bit and has the value 0777 for
root directory permissions, which is certainly a special case when using
RAM-backed (and in general other) filesystems.
Because of these 2 changes, it's no longer needed to maintain the TmpFS
filesystem, hence it's removed (renamed to RAMFS), because the RAMFS
represents the purpose of this filesystem in a much better way - it
relies on being backed by RAM "storage", and therefore it's easy to
conclude it's temporary and volatile, so its content is gone on either
system shutdown or unmounting of the filesystem.
This patch adds a new gradient tool to pixelpaint that allows us to fill
the canvas with a smooth color gradient outline at the edge of the
filled area.
Let's put test files with the tests themselves, instead of a random user
directory. (But still copy them so they appear in the user directory
for convenience.)
I used this utility to check if the possible TGA images' cases for
different origins (explictly the Y origin) are generating the same
bitmap, as I felt that my eyes are not a good-enough measurement tool
for this kind of task.
This might be useful in the future for testing other implementations so
I rather have this nice utility in our codebase.
We do not want to move POSIX utilities into subsections since they have
standard names, but we can do whatever we want with Applications :^).
This is particularly advantageous as many applications contain several
images, which declutters the man1 directory.
We've had quite some instances of people reintroducing these kinds of
links because they didn't know about the "new" help:// scheme. This
check should now prevent that from happening, though it might in rare
circumstances trigger a false positive.
When laying out abspos boxes, we compute the height twice: before and
after the inside of the box has been laid out.
The first pass allows percentage vertical values inside the box to be
resolved against the box's height. The second pass resolves the final
used value for the height of the box itself.
In cases where the box height depends on the results of inside layout,
we were incorrectly setting the box to having a definite zero height.
This led to incorrect results when sizing an abspos flex container,
since the FFC sizes containers (in row layouts) based on whether the
container has a definite height.
To avoid this problem, this patch adds an enum so we can differentiate
between the two abspos height computation passes. If the first pass
discovers a dependency on the inside layout, we simply bail out of
computing the height, leaving it as indefinite. This allows the FFC
to size its container correctly, and the correct height gets set by
the second pass.
The setting of scan code set sequence is removed, as it's buggy and
could lead the controller to fail immediately when doing self-test
afterwards. We will restore it when we understand how to do so safely.
Allow the user to determine a preferred detection path with a new kernel
command line argument. The defualt option is to check i8042 presence
with an ACPI check and if necessary - an "aggressive" test to determine
i8042 existence in the system.
Also, keep the i8042 controller pointer on the stack, so don't assign
m_i8042_controller member pointer if it does not exist.
Similar to the Settings application, this adds a single Screensaver
application to launch all screensaver demos. This is to declutter the
taskbar menu a bit.
We currently hard-code excluding Settings apps from the system menu.
This adds an "ExcludeFromSystemMenu" option to the AppFile configuration
to selectively exclude these apps, which all Settings app now set.
This is to allow selectively excluding a few Demo apps in a future
commit.
This wasn't doing anything interesting enough to justify being its own
demo application. If we need a spinning cube, we can just load a cube
model into 3DFileViewer. :^)
Base+Userland: Add menu item icons
This adds missing icons to Presenter Presentation menu.
This adds missing icon to Image Viewer View menu.
This adds a scale icon for the Image Viewer and Font Editor.
This moves the Fit Image to View icon to the 16x16 folder as it's now
used by Image Viewer and not only Pixel Paint.
This improves the fullscreen and play icons so that they fit together
better.
This was a plain-looking test app for debugging mouse events.
Mouse events work now, and if we want mouse testing facilities, they
can be added to MouseSettings instead.

This utility lets a user to figure out what are the dependency libraries
for an ELF dynamic object, whether it's a dynamically loaded executable
or dynamically loaded library.
Check if the process we are currently running is in a jail, and if that
is the case, fail early with the EPERM error code.
Also, as Brian noted, we should also disallow attaching to a jail in
case of already running within a setid executable, as this leaves the
user with false thinking of being secure (because you can't exec new
setid binaries), but the current program is still marked setid, which
means that at the very least we gained permissions while we didn't
expect it, so let's block it.
Implement collapsing of a box margin-top and first in-flow
child margin-top by saving function that updates y position
of containing block inside BlockMarginState and then for
every child until "non-collapsed through" child is reached
y position of containing block is updated by calling
update_box_waiting_fox_final_y_position_callback.
Fixes a bug where when you had spans that that were bigger than the
grid, would create enough tracks to accomodate them. When a fixed
position is given, there should be at a minimum a row/column available
for the track. The span will be truncated if there is no space for it
later.
This is used during CI to verify that some manual pages are up to date
with the output of the corresponding program's --help option. UE does
not exist on x86_64 yet, so we cannot run `UE --help`. Remove it from
this list for now.
A bug was found where grid items were being drawn outside of the grid if
the item had a large span and the grid was defined as having gaps
between the rows/columns.
This was caused by an erroneous calculation of the
{row,column}_{start,span} properties.
Adapt BMPImageDecoderPlugin to support BMP images included in ICOns.
ICOImageDecoderPlugin now uses BMPImageDecoderPlugin to decode all
BMP images instead of it's own ad-hoc decoder which only supported
32 bpp BMPs.
This shouldn't be necessary but reproducing the odd corrupted profile
data from the nightly Azure runs is proving tricky locally. Hopefully
this will mitigate the issue.
We have a new, improved string type coming up in AK (OOM aware, no null
state), and while it's going to use UTF-8, the name UTF8String is a
mouthful - so let's free up the String name by renaming the existing
class.
Making the old one have an annoying name will hopefully also help with
quick adoption :^)
This adds support for parsing the ::placeholder pseudo-element and
injecting an anonymous layout node with that element when the input
element's data is empty.
The rubber band is the rectangle indicating the selection region on the
desktop, the file manager, and other icon views. If this region is
painted opaque with alpha=ff, the rectangle obscures the icons
underneath, harming the user experience. We set it to 3c like the other
themes.
This utility essentially creates a filesystem sandbox for a specified
command, so it can be tested with only the unveiled paths the user
specifies beforehand.
The Core::System::create_jail function already provided the new jail
index as a result, so it was just a matter of using it when calling the
LibCore join_jail function to use the new jail.
Lasso selection works by allowing the user to draw an arbitrary shape
much like the pen tool and ensuring the shape is closed by connecting
the start/end points when the user is done drawing. Everything inside
the shape becomes the selection.
Selection is determined via an outer flood fill. We begin a flood fill
from a point that is guaranteed to be outside of the drawn shape, and
anything the fill doesn't touch is determined to be the selection
region.
This version can already:
- load all of the defined file format except for the image type and the
frame-specific stuff
- navigate frames and slides (though frames are mostly stubbed out)
- display text with various common settings
- displays text with various fitting and scaling methods
- scale and position objects correctly no matter the window size
This category includes anything useful for getting work done with your
computer. It is mostly a split-off from the Utilites category which was
becoming very large.
The window prototypes alert, confirm, and prompt must "pause" execution
until a response is received from the user. This test page is meant to
ensure that a timeout queued before a prompt is not executed until after
that prompt is closed.
This adds a test of a conic-gradient() with just a center position
and no starting angle.
This also adds a gradient that gives each quadrant a different color,
this is very sensitive to the center position being correct.
This happens in two ways:
1. LibCore now has two new methods for creating Jails and attaching
processes to a Jail.
2. We introduce 3 new utilities - lsjails, jail-create and jails-attach,
which list jails, create jails and attach processes to a Jail,
respectively.
When a flex item has a specific preferred size, that size should be its
contribution to the containers intrinsic sizes.
This fixes an issue on Patreon where the logo would cover the entire
viewport since the SVG had a large intrinsic size but the flex item
containing it had a small specified size in CSS.
Currently, if the script fails, it simply runs "exit 1". This exits the
script, but keeps the VM running, so CI hangs until it times out.
Instead of exiting, write a failure status to an error log and shutdown.
CI can then read that error log and fail the run if needed.

Let's put the power_state global node into the /sys/kernel directory,
because that directory represents all global nodes and variables being
related to the Kernel. It's also a mutable node, that is more acceptable
being in the mentioned directory due to the fact that all other files in
the /sys/firmware directory are just firmware blobs and are not mutable
at all.
This flag doesn't conform to any POSIX standard nor is found in any OS
out there. The idea behind this mount flag is to ensure that only
non-regular files will be placed in a filesystem, which includes device
nodes, symbolic links, directories, FIFOs and sockets. Currently, the
only valid case for using this mount flag is for TmpFS instances, where
we want to mount a TmpFS but disallow any kind of regular file and only
allow other types of files on the filesystem.
Polygonal selection tool allows for the drawing of any arbitrary
polygonal shape. It tracks clicked points in a vector, upon double
clicking we finalize the polygon and generate the selection mask. The
user can press the escape key during selection to cancel.
The mask is generated as follows:
- First we calculate the size of the bounding rect needed to hold the
polygon
- We add 2 pixels to height/width to allow us a 1 pixel border, the
polygon will be centered in this bitmap
- Draw the polygon into the bitmap via Gfx::Painter, making sure to
connect final polygon point to the first to ensure an enclosed shape
- Generate a selection mask the size of the bitmap, with all pixels
initially selected
- Perform a flood fill from (0,0) which is guaranteed to be outside the
polygon
- For every pixel reached by the flood fill, we clear the selected pixel
from the selection mask
- Finally we merge the selection mask like other selection tools.
