---------------------------------
Summary: [SASL] PN_TRANSPORT_ERROR event not raised
Key: PROTON-923
URL: https://issues.apache.org/jira/browse/PROTON-923
Project: Qpid Proton
Issue Type: Bug
Components: proton-c, python-binding
Affects Versions: 0.10
Reporter: Ken Giusti
Assignee: Andrew Stitcher
Priority: Blocker
Fix For: 0.10
I have a pyngus test that exercises the case where the client and server do not
share compatible mechanisms. The purpose of the test is to check pyngus
handling of this misconfiguration.
At a high level, the SASL configuration is:
server_props = {'x-server': True,
'x-sasl-mechs': 'PLAIN'}
client_props = {'x-server': False,
'x-sasl-mechs': 'ANONYMOUS'}
(these x- values are used to set the corresponding properties in proton's
connection and sasl objects)
When this test executes, I do not get a PN_TRANSPORT_ERROR proton event on the
client side, although the outcome is set to indicate a failure occurred.
Below is the debug output from the test. C1 is the server connection, C2 is
the client. Note that C1 gets the PN_TRANSPORT_EVENT failure, but C2 does not:

fail
I suspect the PN_TRANSPORT_FAILURE event that is posted is not coming from the
SASL failure itself, but rather from a framing error occuring on the server
(which in itself is suspect, but that's a matter for a different JIRA)
