- Remove goofy _r suffix from syscall names.
- Don't take a signed buffer size.
- Use Userspace<T>.
- Make TTY::tty_name() return a String instead of a StringView.
This syscall allows a parent process to disown a child process, setting
its parent PID to 0.
Unparented processes are automatically reaped by the kernel upon exit,
and no sys$waitid() is required. This will make it much nicer to do
spawn-and-forget which is common in the GUI environment.
After running a build command, make by default stat()s the command's
output, and if it wasn't touched, then it cancels all build steps
that were scheduled only because this command was expected to change
the output.
Ninja has the same feature, but it's opt-in behind the per-command
"restat = 1" setting. However, CMake enables it by default for all
custom commands.
Use Meta/write-only-on-difference.sh to write the output to a temporary
file, and then copy the temporary file only to the final location if the
contents of the output have changed since last time.
write-only-on-difference.sh automatically creates the output's parent
directory, so stop doing that in CMake.
Reduces the number of build steps that run after touching a file
in LibCore from 522 to 312.
Since we now no longer trigger the CMake special case "If COMMAND
specifies an executable target name (created by the add_executable()
command), it will automatically be replaced by the location of the
executable created at build time", we now need to use qualified paths to
the generators.
Somewhat related to #2877.
Now that document element returns a generic DOM element, we need to
make sure head and body get a html element.
The spec just says to check if the document element is a html element,
so let's do that.
When waiting for a specific message, only consider messages
from the peer endpoint. Otherwise a message with the same id
for the local endpoint may be misinterpreted.
This fixes the Terminal sometimes hanging after bootup because
a local endpoint message is mistaken for the CreateMenuResponse
message.
Also change DOM::Document::document_element() to return an Element*
and not an HTML::HTMLHtmlElement since that's not the only kind of
documentElement we might encounter.
HTMLElement is the only interface that includes ElementContentEditable
in the HTML specification. This makes sense, as Element is also a base
class for elements in other specifications such as SVG,
which definitely shouldn't be editable.
Also adds a test for the attribute based on what Andreas did in the
video that added it.
I noticed on boot, WindowServer was getting an veil error:

With some digging I found out that the ConfigFile class was causing
trying to flush writes of default values, not present in the .ini
file back to disk on destruction of the object.
This sneaky behavior from ConfigFile seems to violate the public facing
semantics of the function (it's const). It also makes it very hard to reason
about the system with technologies like unveil where we are trying to
explicitly state what is exposed to apps, how those exposed items can be
used.
The functionality also doesn't seem to be all that useful, as we'll just
return the default value from the API's anyway.
This change removes the write back of default values.
Breakpoints need to be disabled before we detach from the debugee.
I noticed this while looking into the fact that if you continue
executing a program in sdb (/bin/ls) where you had previously
set a breakpoint, it would crash on sdb exit once the debugee died
with an assert on HashMap destruction where we were iterating
while clearing is set. This change also happens to fix this assert.
- parse_flag now only parses one digit instead of consuming an entirely
valid number
- match_number => match_coordinate
- match_coordinate now returns true if `ch()` is '.'
- parse_number no longer matches a +/-
- Don't crash when encountering one of the three unsupported path
commands. Instead, just skip them. No reason to crash the browser over a
silly SVG element :)
This works everywhere right now, but it's obviously not going to stay
that way forever. :^)
Note that this does not advance the cursor correctly for whitespace
since the cursor is DOM-based and doesn't take whitespace collapsing
into account yet.
Each Web::Frame now has a cursor that sits at a DOM::Position. It will
blink and look like a nice regular text cursor.
It doesn't really do anything yet, but it will eventually.
In preparation for using Userspace<T> in Syscall::SC_setkeymap_params
remove the usage of SC_setkeymap_params from when compiling in kernel
mode. In kernel model we would need to do a bunch of explicit FlatPtr
cats to in order to get it to compile, and it's unused anyway, so just
avoid the pain.
Change #2811 made window title stripes and window title shadow themable,
but it used the same stripe and shadow color for all window modes.
This is fine for the new 'basalt' theme which uses the same color
in all four window modes, but it changed the default theme so that
background windows had brown stripes and a brown shadow.
Instead, make the title stripe and title shadow themable per window mode,
and change the default theme to restore the colors it had before
change #2811: The title stripe color is the same as Border1 for all
window modes, and the title shadow is the same as the title stripe
darkened by 0.6.
This commit adds an implementation of memmem, using the Bitap text
search algorithm for needles smaller than 32 bytes, and a naive loop
search for longer needles.
This prevents windows from being opened directly on top of eachother,
and provides default behavior for when window position is not specified.
The new behavior is as follows:
- Windows that have been created without a set position are assigned one
by WindowServer.
- The assigned position is either offset from the last window that is
still in an assigned position, or a default position if no such window
is available.
This fixes the issue with the exported data having a leading zero,
causing RSA::encrypt to trim the block down, and ruining the encryption.
Fixes#2691 :^)
Some of the remaining instructions have different behavior for
register and non-register ops. Since we already have the
two-level flags tables, model this by setting all handlers in
the two-level table to the register op handler, while the
first-level flags table stores the action for the non-reg handler.
