import bb.event

Need to map our I/O correctly. stdout is a pipe to the server expecting

events. We save this and then map stdout to stderr.

eventfd = os.dup(sys.stdout.fileno()) bb.event.worker_pipe = os.fdopen(eventfd, 'w', 0)

map stdout to stderr

os.dup2(sys.stderr.fileno(), sys.stdout.fileno())

Replace those fds with our own

#logout = data.expand("${TMPDIR}/log/stdout.%s" % os.getpid(), self.cfgData, True) #mkdirhier(os.path.dirname(logout)) #newso = open("/tmp/stdout.%s" % os.getpid(), 'w') #os.dup2(newso.fileno(), sys.stdout.fileno()) #os.dup2(newso.fileno(), sys.stderr.fileno())

Don't read from stdin from the parent

si = file("/dev/null", 'r') os.dup2(si.fileno( ), sys.stdin.fileno( ))

We don't want to see signals to our parent, e.g. Ctrl+C

os.setpgrp()

Save out the PID so that the event can include it the

events
