-------------------------------------

             Summary: CLOSE_WAIT leak following reproducer for PROTON-1023 / PROTON-1024
                 Key: PROTON-1025
                 URL: https://issues.apache.org/jira/browse/PROTON-1025
             Project: Qpid Proton
          Issue Type: Bug
          Components: python-binding
    Affects Versions: 0.10
            Reporter: Pavel Moravec
            Priority: Minor


Following reproducer for PROTON-1023 or PROTON-1024 (attached at the botton), client leaves
some sockets in CLOSE_WAIT state forever.

I tested the reproducer before & after those two fixes and it is present in both. I.e.
this bug is not a regression caused by PROTON-1023 or PROTON-1024.

Reproducer:
(assuming localhost runs qdrouterd that is restarted every 5 seconds in a loop):

{code}
#!/usr/bin/python

from time import sleep
from uuid import uuid4

from proton import ConnectionException

from proton.utils import BlockingConnection

import traceback
import random

while True:
  sleep(random.uniform(0.3,3))
  try:
    conn = BlockingConnection("proton+amqp://localhost:5672", ssl_domain=None, heartbeat=2)
    rec = conn.create_receiver("another_address", name=str(uuid4()), dynamic=False, options=None)
    print "sleeping.."
    sleep(random.uniform(0.3,3))
    rec2 = conn.create_receiver("some_address", name=str(uuid4()), dynamic=False, options=None)
  except ConnectionException:
    try:
      if conn:
        conn.close()
    except Exception, e:
      print e
      print(traceback.format_exc())
{code}
