#include <thread>
std::thread th1(LorisThread, s, socket_address);
std is declared, it makes no diff

welp, i guess i race can happen even between
int pid = ::clone(cloneArgs.fn, cloneArgs.child_stack, cloneArgs.flags, cloneArgs.arg);
int saved_errno = errno;
thread.pid = pid;

that is exactly how i learned :)
loads faster than reading a big book and forgetting half of what you read :)

https://gist.github.com/5de091d0497b3f2912365d90da679173 is this too slow to be useful in debugging data races that can occur in extremely short periods of time (eg ~100ms) ?

try these :)

When you send SIGCONT, the process is resumed.
After it gets resumed, you call waitpid, the waitpid will hang until the process state change.
In your case, waitpid does not catch the resume state because the process has already been resumed before you call waitpid.
It won't hang if you specify WNOHANG.

how do i catch it?
this is my code https://gist.github.com/Total-Control-9985/fff98dfab4efc84d071458d07dbdbd48
and this is my current output https://gist.github.com/Total-Control-9985/c9e09b8bafbe8220ccb295fcd546262d

I don't really know what are you going to do.
But at a glance I notice you did something wrong here.
int status = wait(pid);
The first argument of wait is not PID. It is a pointer to integer which will be the status.

I didn't examine your code carefully.
Anonymous
int wait(pid_t pid)
Anonymous
wait is a wrapper around waitpid
Ammar
int wait(pid_t pid)
I am unsure how can it compile, as I think it will conflict with wait from <sys/wait.h>.
Anonymous
i think it compiles via function overload
Anonymous
eg
pid_t wait(int *wstatus);
int wait(pid_t pid);
Ammar
how tf can this have failed?
kill(pid, SIGCONT);
waitpid(pid, &status, WCONTINUED|WSTOPPED) // hanged
So, in the code you sent, where do you do this?
And why do you need to do?
Anonymous
im gonna upgrade it to std::optional<int> instead so i can distinguish between errors
Ammar
I don't really know which code is being waited. And how resources are managed. You need to explain more, so other can think of a solution.

Because there is no good "tutorials"
How about c++ series from "the cherno" YT channel, I planned to follow this tutorial, what your opinion about this ? 😖😖😖
