- 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.

- Most runtime attributes in the inf. model calculated in runtime from
more fundamental information. (improves consistency)
- sg_assign_si can now recalculate workloads considering existing
assignments
- Logging improvements, similar to what is required as notification in
AMF spec.
- CLC-CLI INSTANTIATE now exits aisexec when it fails (should later be
sent as an NTF alarm)
- CLC-CLI CLEANUP correctly handles already terminated processes
- testamf1.c printouts removed for normal operation
- Iterator functions for SI/CSI assignments

- Revised cluster start
- Includes Steven's "amf invalid write patch"
- Includes "components not started with 0.76" patch
- New timer API use backed out of AMF (temporary)

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)
git-svn-id: http://svn.fedorahosted.org/svn/corosync/trunk@1071 fd59a12c-fef9-0310-b244-a6a79926bd2f
- Use of Distinguished Names (DN) in API and multicast messages
- CSI resassignment properly handled (by using restarting state)
- State 'setter' functions with uniform printouts
- Simple 'assign SU to host' algorithm:
- based on saAmfSUHostedByNode config attribute
- see config file for example
- Debug print runtime attributes upon user request:
$ pkill -USR2 aisexec
- Object-oriented naming of functions started (but not finished)
- testamf1.c updated with some new tests
- Minor fix in print.h and print.c
- AMF can be started on two nodes (example config file needs
modification for this)

The AMF code doesn't detect invalid healthcheck keys and crashes when an
invalid healthcheck key is specified.
