Luau has static typing also
cloud yacht
Normal Lua kinda has classes
I've consumed them but haven't created them myself
They are mostly just tables with methods on them but it has some syntatic sugard where if you go class:function() it passes the class as the first argument
And if you define one that way it adds a self as the first argument
tepid olive
yeah it is pretty cool, but at least me myself never had to use classes in any of my projects, maybe it would've made stuff easier, i dunno

you can find which methods to hook/use with FLEX
and then the rest is trial and error

unless nathan bothers enough to get it working, it wonāt

) ```what am i supposed to put for the label? it says its the label to use for communication, usually the program name
so do i just put whatever? my program refuses to create a diagnostics_relay_client so i assume it comes from the lockdownd_client being invalid

update on the video editor idea to whom it may concern: i think the answer is to write my own sort of loose scripting language that lets you directly access functions and types; you will define everything in rust (and i can figure out some sort of plugin system for making your own custom operations)
the reason i wanted to use an actual scripting language was to take advantage of basic iterator functions like map existing in the language to make things easier, but i think its better if i define everything myself the way i want it in the rust world and make the scripting an adapter to using that

why do we fork() stuff instead of just posix_spawn which is safer
since if you fork, you have to branch into an if to do anything useful anyways
cant you just put the stuff you would have in the if branch into the executable you spawn
rust doesnt even have fork because its deemed too unsafe and problematic
lusty jacinth
what did u order
they are now an epic appel devuwuper
gentle grove
i guess
but instead of duplicating your process you should spawn a new one always imo
thats what i always assumed was the case
i cant understand when you would need to fork specifically
do you have examplse
cloud yacht
I believe node js uses forking for user processes so they can share the same in memory node process
My guess is most interpreted languages do the same

hmmmm ok
youre trying to signal to the child when the parent dies?
every time i search it gives me the reverse of that
oh nevermind
i found sometihng
why isnt this a more common thing
that seems like a kinda obvious thing
no one wants zombies
i have child worker process that should exit if the parent is killed
thats what ithought
not that i have one i mean theoritically
web browser
so wanna kill all the tab processes if the parent manager dies
Child can ask kernel to deliver SIGHUP (or other signal) when parent dies by specifying option PR_SET_PDEATHSIG in prctl() syscall like this:
prctl(PR_SET_PDEATHSIG, SIGHUP);
See man 2 prctl for details.
Edit: This is Linux-only
so wait what even
why is this not a more common thing, wouldnt you always wanna deal with stopping children after parent dies if you happen to have subprocesses
so you dont have zombie processes
steady nest
tldr just use posix_spawn and ignore capt
gentle grove
is it just that your subprocess doesnt really care about the parent's state usually?
steady nest
if you need to clone parent memory youāre doing something wrong
gentle grove
does nginx do worker processes or are they threads
apparently it uses processes??
it also uses full async io so its non blocking which is nice
does it not on other platforms
does the kernel do basically the same thing
steady nest
lies, itās vfork
gentle grove
lies, itās vfork
isnt regular fork cow already
steady nest
itās supposedly better for bigger processes
gentle grove
vfork() is an obsolete optimization. Before good memory management, fork() made a full copy of the parent's memory, so it was pretty expensive. since in many cases a fork() was followed by exec(), which discards the current memory map and creates a new one, it was a needless expense. Nowadays, fork() doesn't copy the memory; it's simply set as "copy on write", so fork()+exec() is just as efficient as vfork()+exec().
oh so i just found out clone() exists
so fork clones and then removes some stuff?
i have many many tabs
where the fuck is main in nginx source
i cant even tell where the build system is or the entrypoint
oh nevermind
why does nginx use subprocesses
thats my new question
where does unistd.h
are these all kernel apis that are just magically included or osmething
since theres no object linked that corresponds to it and these spawn and fork things are not part of libc i dont think
or does libc provide it
i have gone far off track
i was originally trying to read about how go's concurrency model works
no on linux
is macos like windows in that it exposes a libc which wraps the syscalls instead of syscalls being exposed to userspace
do you have to link against libsystem
how does it work
also wdym
how does linux compare for that
where do those c functions come from, are they a dynamic lib on the system that gets linked in or does the kernel inject it in or something
gentle grove
why does nginx use subprocesses
it sounds like its because before linux had posix threads, you could only have 1 thread per process so the entire program was structured around that
gentle grove
its for running it as a "unikernel" so if im udnerstanding that right, that means building nginx directly into the kernel executable (although still userspace)??

Does safemode occur only because "springboard crash" or are there other reasons
My tweak that works fine on jailed via dylib injection; causes a safe mode when trying to install it in a jb even though i use "return;" in a constructor after checking bundleid and if its equal to com.apple.springboard

__attribute__ ((constructor(997))) what's the 997 for??
orchid fulcrum
thanks everyone
orchid fulcrum
`__attribute__ ((constructor(997)))` what's the 997 for??
priority, there are 2 other constructors
slender glade
? shouldn't it be 3 then
orchid fulcrum
hm ? you can put any number between 101 and 60.000(something)
and it compares between eachother, lower runs first
wooden yarrow
? shouldn't it be 3 then
Priority values up to and including 100 are reserved for internal use. If you use these values, the compiler gives a warning. Priority values above 100 are not reserved.

i made sized arrays in C lol
#include <stdio.h>
#include <stdlib.h>
int *create_sized_int_array(int length) {
// size + array length
int *array = malloc(sizeof(int) * (length + 1));
array[0] = length;
return array + 1;
}
int len(int *array) {
// go back to the start of allocated segment
return array[-1];
}
void free_sized_int_array(int *array) {
free(array - 1);
}
void loop(int *array) {
for (int i = 0; i < len(array); ++i) {
printf("array[%d] = %d\n", i, array[i]);
}
}
int main() {
int *array = create_sized_int_array(4);
array[0] = 5;
array[1] = 12;
array[2] = 4;
array[3] = 39;
loop(array);
free_sized_int_array(array);
return 0;
}
its just a fat pointer
but still i think its cool
orchid fulcrum
int* createSizedArray(int lenght) {
int retArray[lenght] ;
return retArray;
}
placid kraken
yeah but you wont have the length information in other functions
youll just have a pointer
youre also returning stack memory which is unsafe
this is the equivalent in elle too lol
use std/io;
fn new_array<T>(i32 length) {
T *array = malloc(#size(i32) + #size(T) * length);
*array = length;
return array + #size(i32);
}
fn free_array<T>(T *array) {
free(array - #size(i32));
}
fn len<T>(T *array) {
return *(array - #size(i32));
}
fn loop<T>(T *array) {
for (i32 i = 0; i < len(array); i += 1) {
io::printf("array[{}] = {}", i, array[i]);
}
}
fn main() {
i32 *array = new_array<i32>(4);
defer free_array(array);
array[0] = 5;
array[1] = 14;
array[2] = 39;
array[3] = 4;
loop(array);
}
C pointer arithmetic operates on elements not the actual pointer as a number so thats why i have to do -1 in C and -#size(int) in elle
actually the fact that C does pointer arithmetic by element makes it really hard to get an exact subtraction so making a sized array for anything other than an int would be kinda hard
although you could cast it to an unsigned long long, subtract 4, and cast it back
cloud yacht
ok so if I wantged to hook native c code, could that tweak be sideloaded
i'm assuming no
ok yeah figured as much
orchid fulcrum
With jit this is possible afaik
wooden yarrow
i made sized arrays in C lol
```c
#include <stdio.h>
#include <stdlib.h>
int *c...
why do u not just make a struct
this also makes it such that no element types other than int work .
placid kraken
this also makes it such that no element types other than int work .
yeah i know
wooden yarrow
its just a fat pointer
also wait aren't fat pointers like part of the pointer itself
not as a element
placid kraken
this is part of the pointer itself
if u want to allocate an array of 4 strings u basically allocate 32 (4*8) + 4 (size) = 36 and shift 4 forwards to just the strings
so now you can do [0] and the pointer arithmetic still works
then when u need the size u just subtract 4 and deref it
placid kraken
this is the equivalent in elle too lol
```rs
use std/io;
fn new_array<T>(i32 le...
and thatās what i do here i guess
this is more intuitive than C imo
wooden yarrow
this is part of the pointer itself
no no that's not what being part of the pointer means
part of pointer means like for eg.
uint128 sized pointer
where the first 64 bits are the length
and the next 64 are the pointer bytes themselves
placid kraken
hmm i see
64 bit length is kinda overkill because i doubt you need to have an array with 4 quadrillion elements
but yeah
either way whenever i see fat pointer i just think anything that has a pointer aswell as extra metadata to go along with it
whether thats the approach i did or using a struct or making a type wide enough to hold the pointer and size at the same time
i see all of those as fat pointers

you just describe what type you wanna take in what and what to do to get a different type out
