Bug: client.__del__ warnings in tests

[jamoore]

When running:

components/tools/OmeroPy $ ant test -DTEST=gatewaytest.annotation

I see lots of these types of warning (I modified client.__del__ to print out the full stack trace):

     [exec] WARNING:omero.client:Ignoring error in client.__del__:<class 'Ice.ConnectionLostException'>
     [exec] Traceback (most recent call last):
     [exec]   File "/private/tmp/chris/components/tools/OmeroPy/target/omero/clients.py", line 316, in __del__
     [exec]     self.closeSession()
     [exec]   File "/private/tmp/chris/components/tools/OmeroPy/target/omero/clients.py", line 749, in closeSession
     [exec]     self.getRouter(oldIc).destroySession()
     [exec]   File "/usr/local/Cellar/zeroc-ice33/3.3.1/python/Glacier2_Router_ice.py", line 113, in destroySession
     [exec]     return _M_Glacier2.Router._op_destroySession.invoke(self, ((), _ctx))
     [exec] ConnectionLostException: Ice.ConnectionLostException:
     [exec] recv() returned zero

Any ideas why a client is hanging around? This might be related to issues such as "too many open files" etc.

There were a lot of changes going in since this was reported in the way the python gateway handles connections. I no longer see these warnings, so I assume we can call this fixed, but passing it back for retesting.

I'm assuming this is fixed.
