Robbie Gemmell created DISPATCH-1453:
----------------------------------------
Summary: Adding "defaultDistribution: unavailable" overrides the
regular handling of transaction coordinator link refusal
Key: DISPATCH-1453
URL: https://issues.apache.org/jira/browse/DISPATCH-1453
Project: Qpid Dispatch
Issue Type: Bug
Affects Versions: 1.9.0
Reporter: Robbie Gemmell
DISPATCH-802 added handling to refuse links to the transaction coordinator
(which has no address, but is a specific target) if a link route to e.g a
broker isnt configured (using DISPATCH-195), and help clarify the reasons for
the refusal.
DISPATCH-803 was added to provide a way for links to adressses that are
otherwise unknown to be refused rather than message routed, by setting
"defaultDistribution: unavailable". This functionality overrides the behaviour
from DISPATCH-802, making it less clear again why a transaction usage attempt
has failed.
>From a JMS client trying to create a transacted session, the failure with
>"defaultDistribution: unavailable" config present looks like:
{noformat}

qd:no-route-to-dest]

While without it,the router sends a more specific error condition, and so the
failure normally looks like:
{noformat}
javax.jms.JMSException: The router can't coordinate transactions by itself, a
linkRoute to a coordinator must be configured to use transactions. [condition =
amqp:precondition-failed]

{noformat}
It would be nicer if the regular coordinator refusal error condition was sent
in both cases.
