Schloming.


Bugs: QPID-5836
    https://issues.apache.org/jira/browse/QPID-5836


Repository: qpid


Description
-------

options need to be iterated to identify possible unknown options. Default 
values (even None, otherwise Python complains it does not know them) have to be 
set before the loop that overwrites the defaults.

This is in my eyes better option than adding an extra check like:

for key in options.keys():
  if key not in ["reconnect", "transport", "port", .. ]:
    raise error

As this check would have to be maintained and there is a risk one forgets to 
add a new connection option there while handling it otherwise.

The code change is more than reasonable but several automated tests failed - 
some of them (like ha_tests.RecoveryTests.test_queue_hold) due to connection 
option protocol:amqp1.0. While that option should be present _only_ for swig 
client that does not call endpoints.py and Connection class. Other test 
failures are not directly related to that "missing" option but I guess it would 
be the indirect reason (some connection supposed to provision something failed 
due to that option, so the provisioning was missing etc.).

Any idea where & why _native_ client sets protocol:amqp1.0 ? (I even added the 
possibility protocol:amqp0-10 but that didnt help, obviously). Automated tests 
results added.

Testing
-------

Automated tests passed.

Manual test with connection option {'a':'b'} raises error:

Traceback (most recent call last):
  File "get_queue_arguments.py", line 17, in <module>
    connection = Connection(brokerurl, **parms)
  File "/usr/lib/python2.6/site-packages/qpid/messaging/endpoints.py", line 
195, in __init__
    raise ConnectionError("Unknown connection option " + key + " with value " + 
value)
qpid.messaging.exceptions.ConnectionError: None(Unknown connection option a 
with value b)
