Rails - Aug 2007 - Daemons in Rails

I tried for quite a few hours in vain to use the Daemons module for
Rails.  Ultimately, Rails was always trying to write to STDOUT and that
is not allowed for real daemons.  No matter where I reopened STDOUT to
write to a file, Rails always seemed to have a reference to the closed
one.

Anyway, so I ended up writing my own daemon process.  It works, but
still remains connected to the shell, so that when I exit, I need to
kill my ssh session.  The daemon still runs, but it''s annoying.

Here is my code.  I tried to emulate what Daemons is supposed to do, but
of course I don''t do everything (e.g. I don''t set the umask,
etc.).
Does anyone have any idea why this would remain attached to the tty?

Regardless, I think this code is probably helpful to people.

Thanks.

if (@@DAEMON)
  puts "Running as daemon.  Output in " + ENV["PWD"] +
"/log"
  $stdout = STDOUT.reopen("log/import-stdout.log", "w")
  $stderr = STDERR.reopen("log/import-stderr.err", "w")
  pid = fork
  if pid
    Process.detach(pid)
  exit
  else
    Process.setsid
    pid = fork
    if pid
      Process.detach(pid)
      exit
    end
  end
end
