Subject fetch() in C++ client never timeouts when connected to Java broker using AMQP 1.0
Date Mon, 02 Feb 2015 23:24:00 GMT
Hi,

While playing with the C++ qpid.messaging client and the Java broker (both
from release 0.30), I noticed that the fetch() command with a timeout never
timeouts. It seems to be reproducible even with the qpid-receive:

qpid-receive -b admin/admin@192.168.33.1:5672 -a "testQueue; { node: {
type: queue } }" --timeout 10 --connection-options "{protocol: amqp1.0}"

>From the log it looks like the Java broker doesn't properly implement the
"synchronous get" feature and keeps the client hanging. Is this known issue
or should I raise a JIRA?

Thanks & Regards
Jakub

[vagrant@localhost ~]$ qpid-receive -b admin/admin@192.168.33.1:5672 -a
"testQueue; { node: { type: queue } }" --timeout 10 --connection-options
"{protocol: amqp1.0}"
