- Application Interface Specification TODO list
- 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: single node may not work too well. Debug this
- mode of operation.
- * 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.
- 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.
- * Create array namespace for each invocation id per connection to avoid
- cross file descriptor contamination.
- * Implement resource proxy functions. (currently dummy functions)
- * Implement pending operations. (currently dummy functions)
- * Implement NWAY and NWAYACTIVE redundancy models.
- Checkpointing
- -------------
- * Very Important: Implement configuration change support. This includes partitions.
- * Implement thread support for checkpointing library.
- * Implement expiration times on checkpoints.
