Creating exchange source routes to different brokers can fail if the channels
overlap.

Key: QPID-3773
URL: https://issues.apache.org/jira/browse/QPID-3773
Project: Qpid
Issue Type: Bug
Components: C++ Broker
Affects Versions: 0.14
Reporter: Ken Giusti
Assignee: Ken Giusti
Fix For: 0.15
The following valid configuration results in a failure to create a second
bridge queue:
./qpidd --auth no --no-data-dir -p 7777 &
./qpidd --auth no --no-data-dir -p 8888 &
./qpidd --auth no --no-data-dir -p 9999 &
[kgiusti@localhost src (trunk)]$ qpid-config -a127.0.0.1:7777 add exchange
topic ex1
[kgiusti@localhost src (trunk)]$ qpid-config -a127.0.0.1:8888 add exchange
topic ex1
[kgiusti@localhost src (trunk)]$ qpid-config -a127.0.0.1:9999 add exchange
topic ex1
[kgiusti@localhost src (trunk)]$ qpid-route -s route add 127.0.0.1:7777
127.0.0.1:8888 ex1 "#"
[kgiusti@localhost src (trunk)]$ qpid-route -s route add 127.0.0.1:9999
127.0.0.1:8888 ex1 "#"
This *should* result in two bridge queues being created on 127.0.0.1:8888; one
queue for the route to :7777, the other for the route to :9999.
What actually happens is one queue is created:
[kgiusti@localhost src (trunk)]$ qpid-stat -q 127.0.0.1:8888

0 0 0 0 0 1 2
...
This is due to the way the broker generates the name for the queue. The format
of the name is "bridge_queue_" + channel# + broker's federation uuid. In the
failure case, the channel # happens to be the same for both routes, which
results in duplicate names for different queues.
