Hi,
For the last days I have been struggling to reap zombies adopted by
the frontend with only failures. I tried several methods using
wait(-1), waidpid and trapping the signal when a child dies without
ever succeeding to reap zombies. This means, I will stop and will
leave the issue open to anyone who can find a working solution. With
zombies or not, the application works. So I will continue with real
development instead of fighting a seeming impossible battle.
The pascal code that I used to reap zombies:
======================================
procedure handle_sigchld(sig: longint; info: psiginfo; context:
psigcontext); cdecl;
var
Status: cint;
a_pid: pid_t;
begin
Status := 0;
a_pid := -1;
{
SIGCHLD
CLD_EXITED child has exited
CLD_KILLED child was killed
CLD_DUMPED child terminated abnormally
CLD_TRAPPED traced child has trapped
CLD_STOPPED child has stopped
CLD_CONTINUED stopped child had continued
}
//CLD_EXITED = 1; CLD_KILLED = 2
if info^.si_code = 2 then
begin
backend_lives := backend_lives + 1;
//fpwaitpid(a_pid, Status, WNOHANG);
//fpwaitpid(info^._sifields._sigchld._pid,
info^._sifields._sigchld._status, WNOHANG);
//fpwait(info^._sifields._sigchld._pid); //,
info^._sifields._sigchld._status, WNOHANG);
//info^._sifields._sigchld._pid:=;
//while fpwait(a_pid) > 0 do;
s := s + inttostr(info^.si_code) + '.';
{ while (fpwaitpid(a_pid, Status, WNOHANG) > 0) do
begin
backend_lives := backend_lives + 1;
end; }
end;
end;
var sa: sigactionrec;
initialization
sa.sa_handler := @handle_sigchld;
fpsigemptyset(&sa.sa_mask);
sa.sa_flags := (SA_RESTART or SA_NOCLDSTOP);
if (fpsigaction(SIGCHLD, @sa, nil) = -1) then
begin
// do nothing
end;
======================================
