Subject [jira] Commented: (AMQCPP-351) Using incorrect peer list in failover transport
Date Wed, 16 Feb 2011 03:06:57 GMT

    [ https://issues.apache.org/jira/browse/AMQCPP-351?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12995131#comment-12995131
] 

Adam Sussman commented on AMQCPP-351:
-------------------------------------

Perusal of the C-sharp client libs show that they are also using ConnectionControl.connectedBrokers
+ ConnectionControl.reconnectTo.  So, the C++ lib is the odd man out.

> 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.
