Description Alan Pevec 2012-06-26 08:49:13 UTC
Description of problem:
If we stop a syslog daemon when running the following program, it
leads to an infinite loop.

Upstream bug report:

Version-Release number of selected component (if applicable):

How reproducible:
Test script in upstream bug report.

send a message to logger
send a message to logger
send a message to logger
( kill rsyslog here)
Traceback (most recent call last):
  File "/usr/lib64/python2.6/logging/handlers.py", line 795, in emit
  File "/usr/lib64/python2.6/logging/handlers.py", line 730, in _connect_unixsocket
  File "/usr/lib/python2.6/site-packages/eventlet/greenio.py", line 167, in connect
    while not socket_connect(fd, address):
  File "/usr/lib/python2.6/site-packages/eventlet/greenio.py", line 37, in socket_connect
    raise socket.error(err, errno.errorcode[err])
error: [Errno 2] ENOENT
send a message to logger

( restart rsyslog here, but test script does not continue)

PS I was NOT able to reproduce on F17 (python-2.7.3-6.fc17.x86_64) where rsyslog is socket activated.
