Robbie Gemmell commented on DISPATCH-506:
-----------------------------------------
I'm not sure that I would send an error in that case (I can see arguments both
ways on that), but I would say that the router probably shouldnt mark the link
as closed in the detach frame being sent, since the actual receiver did not
close the link. It could depend on exactly what link configuration was present
originally, but there are certainly cases that closing the link if the client
dissapears is the wrong thing to do.
> Detach with no "error" sent by router on client TCP connection dropped

> Key: DISPATCH-506
> URL: https://issues.apache.org/jira/browse/DISPATCH-506
> Project: Qpid Dispatch
> Issue Type: Bug
> Affects Versions: 0.6.1
> Reporter: Paolo Patierno
>
> Hi,
> I got the following scenario.
> A router with a link routing configured on address "my_queue".
> A broker hosting "my_queue".
> A Python receiver connected to that queue through the link routing provided
> by the router.
> If I kill the receiver, so the TCP connection between client and router is
> dropped, the client (of course) doesn't send a detach to the broker for the
> link but the router is in charge to do that.
> What happens is that this detach message doesn't contain an "error" field in
> order to distinguish between a clean detach from the client or a detach sent
> by router due to client "brute" disconnection.
> Following the trace I have :
> [0x16e07f0]: <- EOS
> [0x16e07f0]: -> EOS
> Closed 127.0.0.1:42308
> Unexpected poll events: 0020 on 127.0.0.1:42308
> [0x16cf470]:0 -> @detach(22) [handle=0, closed=true]
> [0x16cf470]:0 <- @detach(22) [handle=0, closed=true]
> [0x16cf470]:0 -> @end(23) []
> [0x16cf470]:0 <- @end(23) []
> I think that it could make sense that router sends a detach with "error" when
> something like that happens.
> The current is a bug or a behavior ?
> Thanks,
> Paolo.
