Current behavior

Usecase 1

NCMP CRUD (Create, Read, Update, Delete towards dmi plugin) operation requests do not work after upgrading to latest CPS master if there were registered cmHandles in the database before
I got the following error, it seems that the database migration does not handle if there were cmHandles in the database before, and does not add status to those cmHandles:

{     "status": "500 INTERNAL_SERVER_ERROR",     "message": "State mismatch exception.",     "details": "Cm-Handle not in READY state. cm handle state is null" }

 

Usecase 2

NCMP CRUD operation requests do not work after downgrading to previously working version
After the downgrade I got the following error, so something happened with the database migration during downgrade:

{     "status": "500 INTERNAL_SERVER_ERROR",     "message": "could not extract ResultSet",     "details": "Check logs for details." }

 

Base version:

Expected behavior

NCMP CRUD operations should work for the following scenarios:
register cmHandle on base > searches successful > CRUD request successful > Upgrade to latest version > searches successful > CRUD request successful >  downgrade to previous version  > searches successful > CRUD request successful

 

Reproduction

1. Install a base version  https://gerrit.onap.org/r/gitweb?p=cps.git;a=commit;h=c2c4f5f17441154ded42cbced43bbf8d090b00f4
2. Register a cmHandle
3. Perform ncmp/v1/ch/searches on the registered cmHandle successful
4. Perform a successful get operation on with the registered cmHandle /ncmp/v1/ch/cmhandle_id/data/ds/ncmp-datastore:passthrough-running?resourceIdentifier=Something=1
5. Upgrade with database migration to https://gerrit.onap.org/r/gitweb?p=cps.git;a=commit;h=a59c24e665e30d5d47341b2c77cb65ae7118d849
6. Perform ncmp/v1/ch/searches on the registered cmHandle successful
7. Perform a failing get operation on with the registered cmHandle /ncmp/v1/ch/cmhandle_id/data/ds/ncmp-datastore:passthrough-running?resourceIdentifier=Something=1
           {         "status": "500 INTERNAL_SERVER_ERROR",         "message": "State mismatch exception.",         "details": "Cm-Handle not in READY state. cm handle state is null"         }
8. Downgrade with database migration to https://gerrit.onap.org/r/gitweb?p=cps.git;a=commit;h=c2c4f5f17441154ded42cbced43bbf8d090b00f4
9. Perform ncmp/v1/ch/searches on the registered cmHandle successful
10. Perform a failing get operation on with the registered cmHandle /ncmp/v1/ch/cmhandle_id/data/ds/ncmp-datastore:passthrough-running?resourceIdentifier=Something=1
        {         "status": "500 INTERNAL_SERVER_ERROR",         "message": "could not extract ResultSet",         "details": "Check logs for details."     }
     

Logs:

Failure after upgrade is really talkative without logs too.

Workaround

It works with clean install if there are no registered cmHandles
