noisy log: [stem] INFO: Error while receiving a control message (SocketClosed): received exception "peek of closed file"

logging is too noisy, debug/trace messages are printed as info messages

import time
import logging
import stem
import stem.control

tor_control_password = "..."
tor_control_port = 1234

logger = logging.getLogger('main')

with stem.control.Controller.from_port(port=tor_control_port) as tor:
  logger.info("authenticate")
  tor.authenticate(password=tor_control_password)
  logger.info("signal")
  tor.signal(stem.Signal.NEWNYM)
  while not tor.is_newnym_available():
    logger.info("sleep")
    time.sleep(tor.get_newnym_wait())
logger.info("done")

will produce this noisy log

currently, this shows 19 times the Error while receiving a control message → show only once?

currently, this is using loglevel info → use loglevel debug/trace?

currently, DEBUG: GETCONF is visible by default → hide debug messages by default? (maybe somewhere in my env, i set loglevel to debug, not sure)

workaround: disable logging from stem

import stem.util
stem.util.log.get_logger().propagate = False # disable logging
