-Application Interface Specification TODO list
+The openais standards based cluster framework TODO list
+Last Updated: May 26, 2006
+
+P1 items are to be implemented before Wilson release.  P2 items may be
+implemented in Wilson if interested parties provide patches.  P3 items are
+targeted for Humphrey.
 
 Generic Items
 -------------
-* EVT, DLOCK, MSG APIs functionality need to be developed.
-* Error checking on parameters could use improvement.
-* Allow AIS Executive to configure cluster name.
-* Compliance testing of return values would be helpful.
-* Support B.01.01 version of spec (currently support A.01.01 version).
-* Consider implementing SOCK_SEQPACKET for the AF_UNIX family of sockets on
-  Linux.  This would save an extra system call every time an operation must
-  be done from the API.
-* There are lots of TODO's in the code that need attention.
-
-Group Messaging Interface
--------------------------
-* Very important: implement full EVS semantics when holes occur in
-  delivery messages after a configuration change but before the new
-  configuration is delivered.
-* Very important: block new messages from being multicast until recovery
-  of each service has completed after a configuration change.  This could be 
-  done with a "plug" in the token which "stops" any GMI_PRIO_MED or GMI_PRIO_LOW
-  messages from being multicast until all members of the configuration have 
-  unplugged the token.  Then queued messages in MED or LOW priority can be
-  sent, ensuring correct partition operation.
-* Implement error creation config file to test GMI since all my lossy
-  hardware has been fixed.
-* Add secrecy/authentication to group messaging interface.
-* Add support for multiple rings with gateway ring to ring for added scalability
-  in LANs.
-* Add support for multiple rings with gateway tuned to long haul networks for
-  added scalability in WANs.  Look at spread.org as a design.
-* Add support for low delivery-time delay FIFO messages.
-* Add support for SAFE ordering.
-* Add support for encryption/authentication using Helix.  nonce will start
-  at zero and increment for every message sent or rotation on the ring.  Group
-  key produced using group key generation protocol.
-  
-Cluster Membership
-------------------
-* Make timeout on SaClmClusterNodeGet work.  Currently the timeout is 5
-  seconds, but the spec requires the timeout to be specified in the API call.
+* P1 32/64 bit cross-endian must be working.
+* P2 Itemize any changes required for AIS B.02.01 in the TODO list.
+* P2 doxygen-ize the include and lib directories.
+* P2 There are many TODOs in the code that need attention.
+* P2 Implement static voting virtual synchrony filter.
+* P3 Integrate with rgmanager system.
+* P3 doxygen-ize the exec directory.
+* P3 Advanced Synchronization Engine needed to synchronize data without
+     long blocking delays during configuration changes.
 
-Availability Management Framework
----------------------------------
-* Very Important: Implement configuration change support.  This includes partitions.
-* Currently the executive can record and manage only one component service
-  instance per component.  As a result, one component cannot act as standby/active
-  for two other components in the system (AIS Spec page 74 Figure 16. Example of
-  n+1 redundancy model).
-  - Fix to follow spec.
-* If a user of the AMF library doesn't respond with saAmfResponse, the state
-  of the application will never change.  Fix by adding timeouts to readiness state
-  and ha state changes to force saAmfResponse state changes triggered.
-* Implement resource proxy functions. (currently dummy functions)
-* Implement pending operations. (currently dummy functions)
-* Implement NWAY and NWAYACTIVE redundancy models.
+Totem
+-----
+* P1 Test scalability to 128 processors.
+* P1 Implement safe message delivery (for both Wilson and Picacho).
+* P1 Add mechanism to reenable a redundant ring after that ring has been
+     declared faulty and then repaired by the system administration.
+* P1 In redundant ring configuration disallow binding to localhost interface.
+* P2 Flush totem messages during RECOVERY state that are in the
+     new_message_queue.
+* P2 Turn totem layer into an LCR component.
+* P3 Implement the totem multiring protocol.
+
+YKD Virtual Synchrony Filter
+----------------------------
+* P2 Scale to 128 processors.
+
+LCR
+---
+* P2 Finish live component replacement services.
 
 Checkpointing
 -------------
-* Very Important: Implement configuration change support.  This includes partitions.
-* Implement expiration times on checkpoints.
+* P1 32/64 bit cross-endian must be working.
+* P1 There is a bug in that iteration doesn't work under heavy load that
+     must be fixed.
+* P1 Creation/deletion of checkpoints should be done using SAFE messaging.
+* P1 The checkpoint unlink operation doesn't work as per specification.  The
+     specification says that a checkpoint unlink should then allow a new
+     checkpoint with the same name to be created.  All cluster members using
+     the old checkpoint continue to use the old checkpoint until they all
+     stop using the checkpoint, at which point the checkpoint should be removed
+     from the cluster. 
+* P2 Conformance testing via SAF-TEST needs to reach 100%.
+
+Distributed Locking Service
+---------------------------
+* P1 32/64 bit cross-endian must be working.
+* P1 Distributed locking needs configuration change support.
+* P1 Provide kernel-based DLM service handler for distributed locking.
+* P2 Conformance testing via SAF-TEST needs to reach 100%.
+
+Messaging Service
+-----------------
+* P2 32/64 bit cross-endian must be working.
+* P2 Finish implementation.
+* P2 Conformance testing via SAF-TEST needs to reach 100%.
+
+Availability Management Framework
+---------------------------------
+* P1 32/64 bit cross-endian must be working.
+* P1 Finish next generation state machine design.
+* P1 Implement next generation state machine design.
