New cluster member pushes store when joining an active cluster.

2010-03-12T20:11:31+00:00

Previously a broker with a clean store would not be able to join an
active cluster because the shtudown-id did not match. This commit
ensures that when a broker joins an active cluster, it always pushes
its store regardless of status. Clean/dirty status is only compared
when forming an initial cluster.

This change required splitting initialization into two phases:

PRE_INIT: occurs in the Cluster ctor during early-initialize. This
phase determines whether or not to push the store.

INIT: occurs after Cluster::initialize and does the remaining
initialization chores.

Minor cleanup: removed unused parameter of initial-status in cluster.xml.

Fix cluster elder calculation to ensure unique elder.

2010-01-27T20:56:31+00:00

Race condition in the previous algorithm allowed several cluster
members to consider themselves the elder.

Added config-seq counter to track config changes since cluster init.

2010-01-06T17:01:50+00:00

    Config-seq is recorded persitently to help identify best store when
    recovering from total failure.

Verify stored cluster-id matches agreed cluster-id when joining a persistent cluster.

Support for restarting a persistent cluster.

2009-11-24T20:07:24+00:00

Option --cluster-size=N: members wait for N members before recovering store.
Stores marked as clean/dirty. Automatically recover from clean store on restart.
Stores marked with UUID to detect errors.

Not yet implemented: consistency checks, manual recovery from all dirty stores.

Added cluster option --cluster-size.

2009-11-18T17:26:43+00:00

--cluster-size=N means that during start-up the cluster waits to have N members
before accepting any clients.
