This way, if you press F2 to edit the name of an item, the name will be
selected in the editor that pops up, and you can start typing a new
name for it immediately.
Move the shadow 1 more pixel away from the unhovered icon location,
making a total 2 pixel distance between the icon and the shadow.
Also tweak the shadow color to be a darkened variant of the base color
underneath the icon.
This was a goofy kernel API where you could assign an icon_id (int) to
a process which referred to a global shbuf with a 16x16 icon bitmap
inside it.
Instead of this, programs that want to display a process icon now
retrieve it from the process executable instead.
Problem:
- C functions with no arguments require a single `void` in the argument list.
Solution:
- Put the `void` in the argument list of functions in C header files.
This new flag controls two things:
- Whether the kernel will generate core dumps for the process
- Whether the EUID:EGID should own the process's files in /proc
Processes are automatically made non-dumpable when their EUID or EGID is
changed, either via syscalls that specifically modify those ID's, or via
sys$execve(), when a set-uid or set-gid program is executed.
A process can change its own dumpable flag at any time by calling the
new sys$prctl(PR_SET_DUMPABLE) syscall.
Fixes#4504.
Make it possible to bail out of ELF::Image::for_each_program_header()
and then do exactly that if something goes wrong during executable
loading in the kernel.
Also make the errors we return slightly more nuanced than just ENOEXEC.
POSIX says we can set errno EINVAL and return -1 if the action is not
supported. This is better than crashing, and fixes bash crashing
whenever you press ^C.
This commit gets rid of ELF::Loader entirely since its very ambiguous
purpose was actually to load executables for the kernel, and that is
now handled by the kernel itself.
This patch includes some drive-by cleanup in LibDebug and CrashDaemon
enabled by the fact that we no longer need to keep the ref-counted
ELF::Loader around.
It was really weird that ELF loading was performed by the ELF::Loader
class instead of just being done by the kernel itself. This patch moves
all the layout logic from ELF::Loader over to sys$execve().
The kernel no longer cares about ELF::Loader and instead only uses an
ELF::Image as an interpreting wrapper around executables.
Now that the CrashDaemon symbolicates crashes in userspace, let's take
this one step further and stop trying to symbolicate userspace programs
in the kernel at all.
Let's just say no to shenanigans by capping images at 16384 pixels both
wide and tall. If a day comes in the future where we need to handle
images larger than this, we can deal with it then.
We now configure the gcc spec files to use a different crt files for
static & PIE binaries.
This relieves us from the need to explicitly specify the desired crt0
file in cmake scripts.
I think this is okay, the main thing to protect against is new versions
of the format that we don't know about yet.
This happens because an .S file compiled into libc.so has version 2
instead of version 4 like everything else.
Fixes#4491.
POSIX allows the default streams (stdin, stdout and stderr) to be
macros, which means that on such systems (musl libc is one) building
Lagom will fail due to the File::std*() names.
Also fix any files that use these identifiers.
