Trying to have a new python process forked off an original doesn't work out well and ends up having race issues. To avoid this, exec() a new bitbake server process. This starts with a fresh python interpreter and resolves various atexit and other multiprocessing issues once and for all.

Replace standard fds with our own
with open('/dev/null', 'r') as si: os.dup2(si.fileno(), sys.stdin.fileno())
so = open(logfile, 'a+') os.dup2(so.fileno(), sys.stdout.fileno()) os.dup2(so.fileno(), sys.stderr.fileno())
Have stdout and stderr be the same so log output matches chronologically
and there aren't two seperate buffers
sys.stderr = sys.stdout
logger = logging.getLogger("BitBake")
Ensure logging messages get sent to the UI as events
handler = bb.event.LogHandler() logger.addHandler(handler)
bb.server.process.execServer(lockfd, readypipeinfd, lockname, sockname, timeout, xmlrpcinterface)
