The best way is to code the app itself to trap a custom signal (e.g. USR1)
and exit gracefully yourself when it's received. The server will reload
the app afterwards.
For an active app this works:
=============
int do_exit = 0;
void s_usr1() {
do_exit = 1;
(void)signal(SIGUSR1,s_usr1);
}
main()....
(void)signal(SIGUSR1,s_usr1);
/* The accept loop */
while(!do_exit && FCGI_Accept() >= 0) {
...
}
FCGI_Finish(); /* end of loop */
}
=============
For a less active app you might try
void s_usr1() {
FCGI_Finish();
exit(0);
}
although I don't know if it works everywhere.
