Possibility to set process name

[henrywood]

I would suggest the possibility of setting the process name (as seen by ps or top) of master and workers via two options to the server process:

--worker-procname "Somename [worker]" and --master-procname "Somename [master]"

as done in this C code below:

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <sys/prctl.h>
#include <errno.h>

int main(int argc, char *argv[]) {
    if (argc != 2) {
        fprintf(stderr, "Usage: %s <NewName>\n", argv[0]);
        return EXIT_FAILURE;
    }

    char *new_name = argv[1];

    // Ensure the new name is not longer than 15 characters
    if (strlen(new_name) > 15) {
        fprintf(stderr, "Error: Process name cannot be longer than 15 characters\n");
        return EXIT_FAILURE;
    }

    // Change the name of the current process
    if (prctl(PR_SET_NAME, (unsigned long)new_name, 0, 0, 0) != 0) {
        perror("prctl(PR_SET_NAME)");
        return EXIT_FAILURE;
    }

    printf("Successfully changed the name of the current process to %s\n", new_name);
    while (1) {
        sleep(1); // Keep the process running to observe the name change
    }

    return 0;
}

I thought this was what the --master-name option did, but apparently not...

(what exactly does the --master-name option do ?)
