Ganesh Murthy commented on DISPATCH-802:
----------------------------------------
Currently the return attach looks like this -
{noformat}
[2016906257:1] <-
Attach{name='qpid-jms:coordinator:ID:db8ca07c-92cf-4f9f-a1eb-492b220709dc:1:1',
handle=0, role=RECEIVER, sndSettleMode=MIXED, rcvSettleMode=FIRST,
source=Source{address='null', durable=NONE, expiryPolicy=SESSION_END,
timeout=0, dynamic=false, dynamicNodeProperties=null, distributionMode=null,
filter=null, defaultOutcome=null, outcomes=null, capabilities=null},
target=Target{address='null', durable=NONE, expiryPolicy=SESSION_END,
timeout=0, dynamic=false, dynamicNodeProperties=null, capabilities=null},
unsettled=null, incompleteUnsettled=false, initialDeliveryCount=0,
maxMessageSize=0, offeredCapabilities=null, desiredCapabilities=null,
properties=null}
{noformat}
but instead should look like this (target=null)
{noformat}
[2016906257:1] <-
Attach{name='qpid-jms:coordinator:ID:db8ca07c-92cf-4f9f-a1eb-492b220709dc:1:1',
handle=0, role=RECEIVER, sndSettleMode=MIXED, rcvSettleMode=FIRST,
source=Source{address='null', durable=NONE, expiryPolicy=SESSION_END,
timeout=0, dynamic=false, dynamicNodeProperties=null, distributionMode=null,
filter=null, defaultOutcome=null, outcomes=null, capabilities=null},
target=null, unsettled=null, incompleteUnsettled=false, initialDeliveryCount=0,
maxMessageSize=0, offeredCapabilities=null, desiredCapabilities=null,
properties=null}
{noformat}
[~gemmellr] is that correct?
I also saw your other comment about amqp:precondition-failed and I will modify
the code to do the same.
> refuse transaction coordination links if they can't be routed to a coordinator
> ------------------------------------------------------------------------------
>
> Key: DISPATCH-802
> URL: https://issues.apache.org/jira/browse/DISPATCH-802
> Project: Qpid Dispatch
> Issue Type: Bug
> Affects Versions: 0.8.0
> Reporter: Robbie Gemmell
> Assignee: Ganesh Murthy
> Fix For: 1.0.0
>
>
> The router is accepting transaction coordinator links even if the support
> from DISPATCH-195 is not being used to link-route them somewhere that can
> handle coordination. If the router can't link-route to a coordinator, and
> knows it can't coordinate transactions itself, it shouldn't accept the links
> to begin with but rather refuse them so clients know they will never work and
> why.
> Prior to 0.8.0, credit was also given on these links, allowing attempt to
> declare transactions. From 0.8.0 no credit is given since there is no
> receiver, so clients have no way to use the accepted link and no indication
> why.
