Charles E. Rolke resolved PROTON-2313.
--------------------------------------
Resolution: Not A Bug
Thanks for your attention to this issue.
The dispatch test self test needs to accept any PN_TRANSPORT_ERROR condition as
a test success.
> [proton-c] Connection to unresolvable address returns retry instead of failure

> Key: PROTON-2313
> URL: https://issues.apache.org/jira/browse/PROTON-2313
> Project: Qpid Proton
> Issue Type: Bug
> Components: proton-c
> Affects Versions: proton-c-0.33.0
> Reporter: Charles E. Rolke
> Priority: Major
>
> A qpid-dispatch self test tries to open a connector (outgoing connection) to
> an unresolvable address.
> [https://github.com/apache/qpid-dispatch/blob/0634a070aa6f902bf5b6f9537a5406e4cfc5a0d5/tests/system_tests_bad_configuration.py#L105]
> The expectation is that proton will return a proton:io error. This does not
> appear to be a regression as the issue exists in 0.33.0.
> {code:java}
> Fedora 31 64-bit bare metal
