The instantiaton of the component is performed with some new steps:
1. SU invoke Comp to instantiate
2. Comp multicast a new event
MESSAGE_REQ_EXEC_AMF_COMPONENT_INSTANTIATE
3. Comp receive the new event
MESSAGE_REQ_EXEC_AMF_COMPONENT_INSTANTIATE
4. If the Comp is within the SU hosted on the node. The
component invokes
the clc_cli instantiate script to start the component
and start a timer
to supervise the start and registration of the component.
5. If the instantiation time elapse before the component has
registered himself
Comp is sending a new multicasted event
MESSAGE_REQ_EXEC_AMF_COMPONENT_INSTANTIATE_TMO.
6. Comp receive
MESSAGE_REQ_EXEC_AMF_COMPONENT_INSTANTIATE_TMO event.
7. The Comp presence state is set to
SA_AMF_PRESENCE_INSTANTIATION_FAILED
8. When all Components are in presence state
SA_AMF_PRESENCE_INSTANTIATED or
SA_AMF_PRESENCE_INSTANTIATION_FAILED the start or restart will
continue with
the assignment of load.
This implemntation means that the complete instantiation procedure
never will be endlessly waiting for a register. The
instantiation will
either turn out in a component instantiation failure or a success.
Hardening of the cluster start use case:
1. A clearer separation of the responsibilities between
amf_cluster and
amf_application.
2. A clearer interface and separation between amf_main (amf.c) and
amf_cluster.
3. A clearer interface and separation between amf_cluster
and amf_node.
4. A clearer separation of the responsibilities between amf_node and
amf_application.

initially in an order such that at least two nodes start after at least one
node has been started and its SUs has been instantiated.

The call to gethostbyaddr() has been removed. This has been replaced by a
protocol where each node multicasts its hostname (obtained with gethostname()).
- "Logical AMF nodes"
The AMF node name is no longer a hostname. The saAmfNodeClmNode
configuration attribute of the AMF node is now the hostname. This config
attribute is now mandatory. The change to amf.conf file shows required changes.
- Some other AMF sync bug fixes

2. Improvement of the use case 'Amf node join'
3. Improvement to manage more than one SG within an Application.
4. Improvement to manage an arbitrary number of Csi-assignments associated
to the Csi

- One AMF node reads the AMF config file (IMM style)
- One AMF node syncs others AMF nodes
- One AMF object is serialized and sent as one message
- Serialization/deserialization of most objects is trivial (memcpy)
except for component and csi-attributes objects which have variable size
arrays/strings.
- Depth first AMF object tree traversal preserves relations when syncing
- Ordered lists of SUs and SIs
- Constructors/destructor per class
- Serializers/deserializers per class
- Config-change changes sync state
- Sync callbacks executes the sync
- "Use case" tracing for sync using the SYNCTRACE macro (trace6)
- Sync master is initially the winner of a timeout race and if the
master leaves the cluster, the node with the lowest node ID becomes new master.
- amf_malloc implements an AMF central malloc routine with error handling.

model). A central header file (amf.h) keeps all the definitions and
prototypes needed.
New things apart from that:
- some doxygen html generated from AMF e.g. each file has a description
- saAmfHAStateGet() now works
- component invoked healthchecks implemented (but not tested)
