Otherwise, we end up propagating those dependencies into targets that
link against that library, which creates unnecessary link-time
dependencies.
Also included are changes to readd now missing dependencies to tools
that actually need them.

This is a partial revert of commit 7af5eef. After 97d15e9, the 'proc'
promise is not needed for operations using getsid().
This also fixes launching several applications in which 7af5eef added
the 'proc' promise only in the second call to pledge().

This commit does three things atomically:
- switch over Core::Account+SystemServer+LoginServer to sid based socket
names.
- change socket names with %uid to %sid.
- add/update necessary pledges and unveils.
Userland: Switch over servers to sid based sockets
Userland: Properly pledge and unveil for sid based sockets

None of these are overridden, and NetworkWidget is a final class.

This is always false, so we can do without it and simplify things a
little.

This is a very small change to improve consistency between applet
context menu item names.

|
Now uses the Selection ColorRole for the active desktop and a
slightly darkened Window for inactive ones. Several themes use
the same color for thread highlighting and inactive windows which
was causing frames to draw without the correct perception of depth.

Thanks Dex for pointing this out! :^)

Previously you had to open Display Settings and navigate to the
"Workspaces" tab in order to edit workspace settings. This patch adds a
context menu shortcut to the same place.
|
|
Instead of collapsing to a 1x1 applet, we now hide the applet window
entirely, which stops it from taking up space in the system tray.
|
|
This patch makes the picker applet react instantly to a click on a
workspace or scroll on the widget, instead of waiting for an event from
WindowServer and as such until the switching animation has ended. This
synchronises the switching with the overlay shown.
Note that WindowServer events will still get handled in case the
workspace were to be updated from somewhere else.
|
|
This patch updates the spelling of "col" to be "column" and
"v{col,row}s" to be spelled out as "workspace_{row,column}s".

Adding a context menu which lists configured keymaps and allows
setting the active keymap

The automatic nomenclature change for IPC sockets got this one wrong.
|

There's no such supervisor pages concept, so there's no need to call
physical pages with the "user_physical" prefix anymore.

This prevents us from needing a sv suffix, and potentially reduces the
need to run generic code for a single character (as contains,
starts_with, ends_with etc. for a char will be just a length and
equality check).
No functional changes.

Each of these strings would previously rely on StringView's char const*
constructor overload, which would call __builtin_strlen on the string.
Since we now have operator ""sv, we can replace these with much simpler
versions. This opens the door to being able to remove
StringView(char const*).
No functional changes.
|
|
Error::from_string_literal now takes direct char const*s, while
Error::from_string_view does what Error::from_string_literal used to do:
taking StringViews. This change will remove the need to insert `sv`
after error strings when returning string literal errors once
StringView(char const*) is removed.
No functional changes.
|
|
StringView was used where possible. Some utilities still use libc
functions which expect null-terminated strings, so String objects were
used there instead.

(Previously, it would open the performance monitor tab)

This makes the wrapper more like the rest in LibCore, and also
removes the annoying limitation of not supporting arguments.
There are three overloads one for String, char const *, and StringView
argument lists. As long as there are <= 10 arguments the argv list
will be allocated inline, otherwise on the heap.

Previously, we were sending Buffers to the server whenever we had new
audio data for it. This meant that for every audio enqueue action, we
needed to create a new shared memory anonymous buffer, send that
buffer's file descriptor over IPC (+recfd on the other side) and then
map the buffer into the audio server's memory to be able to play it.
This was fine for sending large chunks of audio data, like when playing
existing audio files. However, in the future we want to move to
real-time audio in some applications like Piano. This means that the
size of buffers that are sent need to be very small, as just the size of
a buffer itself is part of the audio latency. If we were to try
real-time audio with the existing system, we would run into problems
really quickly. Dealing with a continuous stream of new anonymous files
like the current audio system is rather expensive, as we need Kernel
help in multiple places. Additionally, every enqueue incurs an IPC call,
which are not optimized for >1000 calls/second (which would be needed
for real-time audio with buffer sizes of ~40 samples). So a fundamental
change in how we handle audio sending in userspace is necessary.
This commit moves the audio sending system onto a shared single producer
circular queue (SSPCQ) (introduced with one of the previous commits).
This queue is intended to live in shared memory and be accessed by
multiple processes at the same time. It was specifically written to
support the audio sending case, so e.g. it only supports a single
producer (the audio client). Now, audio sending follows these general
steps:
- The audio client connects to the audio server.
- The audio client creates a SSPCQ in shared memory.
- The audio client sends the SSPCQ's file descriptor to the audio server
with the set_buffer() IPC call.
- The audio server receives the SSPCQ and maps it.
- The audio client signals start of playback with start_playback().
- At the same time:
- The audio client writes its audio data into the shared-memory queue.
- The audio server reads audio data from the shared-memory queue(s).
Both sides have additional before-queue/after-queue buffers, depending
on the exact application.
- Pausing playback is just an IPC call, nothing happens to the buffer
except that the server stops reading from it until playback is
resumed.
- Muting has nothing to do with whether audio data is read or not.
- When the connection closes, the queues are unmapped on both sides.
This should already improve audio playback performance in a bunch of
places.
Implementation & commit notes:
- Audio loaders don't create LegacyBuffers anymore. LegacyBuffer is kept
for WavLoader, see previous commit message.
- Most intra-process audio data passing is done with FixedArray<Sample>
or Vector<Sample>.
- Improvements to most audio-enqueuing applications. (If necessary I can
try to extract some of the aplay improvements.)
- New APIs on LibAudio/ClientConnection which allows non-realtime
applications to enqueue audio in big chunks like before.
- Removal of status APIs from the audio server connection for
information that can be directly obtained from the shared queue.
- Split the pause playback API into two APIs with more intuitive names.
I know this is a large commit, and you can kinda tell from the commit
message. It's basically impossible to break this up without hacks, so
please forgive me. These are some of the best changes to the audio
subsystem and I hope that that makes up for this :yaktangle: commit.

This is the name that is used for every other collection type so let's
be consistent.

This resource graph applet shows incoming network traffic graphically,
and the tooltip shows both TX and RX. The data of all adapters is
combined. The scale of the applet auto-adapts to the shown traffic load.

Makes copy history a bit more informative by showing the code point
range of the selection copied, or the individual character if the
selection contains only one glyph.

This matches the rename of RGBA32 to ARGB32. It also makes more sense
when you see it used with 32-bit hexadecimal literals:
Before:
Color::from_rgba(0xaarrggbb)
After:
Color::from_argb(0xaarrggbb)

Rename WindowManagerServerConnection=>ConnectionToWindowManagerServer.
This was done with CLion's automatic rename feature.

This was done with CLion's automatic rename feature and with:

find . -name ClientConnection.cpp

Uses the new Window FrameShape. Fixes margins for erroneously
elided CheckBoxes. Demystifies the numbers used to calculate the
slider window rect.

Add a Time column to ClipboardHistory that shows the time when each
item in the list was copied.

pledge_domains() that takes only one String argument was specifically
added as a shortcut for pledging a single domain. So, it makes sense to
use singular here.
