Subject [jira] Created: (AMQCPP-351) Using incorrect peer list in failover transport
Date Wed, 16 Feb 2011 03:00:57 GMT
Using incorrect peer list in failover transport

                 Key: AMQCPP-351
             Project: ActiveMQ C++ Client
          Issue Type: Bug
          Components: Transports
    Affects Versions: 3.2.4
            Reporter: Adam Sussman
            Assignee: Timothy Bish

In the failover transport, the broker hands the client a list of known peer brokers the client
can attempt upon connection failure.  In the Java client libs, this list of peers is obtained
from the ConnectionControl object and that list is subject to various configuration controls
on the broker.  The C++ client gets its list from the BrokerInfo object who's list is NOT
controlled at all by broker settings and which also retains query string artifacts that should
not be used (see AMQ-3124).

The list of peers the C++ client is using is not correct and not under the same controls as
the list the Java client is using. The C++ failover transport should be altered to use the
same source of peer data as the Java client, the ConnectionControl object.

In currently released versions (3.2.4 and older), the entire reconnect list comes from BrokerInfo.getPeerBrokerInfos.
 In trunk, the list comes from BrokerInfo.getPeerBrokerInfos PLUS ConnectionControl.getReconnectTo.
 However, the Java client gets its list from ConnectionControl.getConnectedBrokers plus ConnectionControl.getReconnectTo
and does not use BrokerInfo at all.

At a minimum, the usage of BrokerInfo.getPeerBrokerInfos needs to be removed in FailoverTransportListener.cpp
and usage of getConnectedBrokers needs to be added to FailoverTransport.cpp:handleConnectionControl.
