It replaced a muti-deque implementation with o(1) complexity for consuming with a map implementation with o(log(n)) performance. This revision returns to a mutli-deque algorithm but with the addition of a FIFO index for fast browsing of acquired and unacquired messages. git-svn-id: https://svn.apache.org/repos/asf/qpid/trunk@1329301 13f79535-47bb-0310-9956-ffa450edef68 
Revision r1307582 created a serious degredation in priority queue performance.

It replaced a muti-deque implementation with o(1) complexity for consuming with
a map implementation with o(log(n)) performance.

This revision returns to a mutli-deque algorithm but with the addition
of a FIFO index for fast browsing of acquired and unacquired messages.

QPID-3603: Keep acquired messages on queues for all queue types. 2012-03-30T19:36:48+00:00 Alan Conway aconway@apache.org 2012-03-30T19:36:48+00:00 e54ef8dc737196343ad974c91a86681efca5fb14 Updated priority and lvq queues to keep acquired messages, and supply them to browsers if requested. This is necessary so replicating subscriptions can back-up these queue types without message loss. git-svn-id: https://svn.apache.org/repos/asf/qpid/trunk@1307582 13f79535-47bb-0310-9956-ffa450edef68

QPID-3652: Fix cluster authentication. 2011-12-06T15:56:40+00:00 Alan Conway aconway@apache.org 2011-12-06T15:56:40+00:00 ae0f67263950f41ce6078a9fde79be78d47f4a11 Only allow brokers that authenticate as the cluster-username to join a cluster. New broker first connects to a cluster broker authenticates as the cluster-username and sends its CPG member ID to the qpid.cluster-credentials exchange. The cluster broker that subsequently acts as updater verifies that the credentials are valid before connecting to give the update. NOTE 1: If you are using an ACL, the cluster-username must be allowed to publish to the qpid.cluster-credentials exchange. E.g. in your ACL file: acl allow foo@QPID publish exchange name=qpid.cluster-credentials NOTE 2: This changes the cluster initialization protocol, you will need to restart the cluster with all new version brokers. git-svn-id: https://svn.apache.org/repos/asf/qpid/trunk@1210989 13f79535-47bb-0310-9956-ffa450edef68
