#2398 imm: retry of ccb abort should be allowed if failed with TRY_AGAIN and TIMEOUT

[Neelakanta Reddy]

steps :
1. create a ccb
2. saImmOmCcbAbort the ccb, the return code should be TRY_AGAIN, which can be re-produced when fevs queue is full
T2 Too many pending incoming FEVS messages (> 16) enqueueing async message. Backlog:1

The saImmOmCcbAbort ccb will create the imma_newCcbId, without finalizing old ccbid.

solution:
do not create new ccbid when the return code is TRY_AGAIN or TIMEOUT

[Anders Bjornerstedt]

TRY_AGAIN ok.

But ERR_TIMEOUT ? Not sure what you are doing here.

The two error codes are different in meaning.

TRY_AGAIN means the client KNOWS that the call was NOT processed.

TIMEOUT mens the client does NOT KNOW if the call was processed in the server or not.
TIMEOUT may be (is typically) generated in the client library when the client has waited too long
for a response from the server.

[Neelakanta Reddy]

The problem here is to avoid newccbid when the old ccbid is not finalized when saImmOmCcbAbort is called.

If the TIMEOUT is returned, then the agent may re-try saImmOmCcbAbort, to avoid old ccb not finalized. If the old ccb is finaized, then server will return BD_HANDLE, which is converted to SA_AIS_OK in library.
