Bug 807769

Description of problem:

Need to be sure that missing consumer cert is handled properly by getsecret() in pulp agent (gofer plugin)

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

1.0

How reproducible:

Not very.  Relies on race condition where an RMI is queued and journal(ed) locally by gofer but the cert is gone.

Steps to Reproduce:
1. Register consumer
2. hack pulpplugin and make duration between polling for cert changes long.
3. unregister the consumer in pulp.
  
Actual results:

Exceptions defined below in the log.

Expected results:

Should raise exception to unregisterted() RMI and be done.  Might be working properly but need to walk though it to be sure.  Log suggests otherwise.
