If we stop a syslog daemon when running the following program, it
leads to an infinite loop.
==
#!/usr/bin/env python
import eventlet
from logging.handlers import SysLogHandler
import time
import logging
eventlet.patcher.monkey_patch(all=False, socket=True)
logger = logging.getLogger('log')
logger.addHandler(SysLogHandler('/dev/log'))
while True:
print "send a message to logger"
logger.error("syslog test")
time.sleep(1)
==
It is because there is a close leak in the python logging module, and
SysLogHandler continues to send a log message against the closed
connection forever.
The following patch seems to fix this problem:
