[Linux-cluster] Tools always return EXIT_FAILURE

[Aravind Parchuri]

I hope I'm not missing something obvious, but could someone tell me why 
ccs_tool exits with "EXIT_FAILURE" even when it's completed the 
requested operation successfully?


    else if(!strcmp(argv[optind], "addnode")){
	    add_node(argc-1, argv+1);
	    exit(EXIT_FAILURE);
     }
     else if(!strcmp(argv[optind], "delnode")){
	    del_node(argc-1, argv+1);
	    exit(EXIT_FAILURE);
     }
     else if(!strcmp(argv[optind], "addfence")){
	    add_fence(argc-1, argv+1);
	    exit(EXIT_FAILURE);
     }
     else if(!strcmp(argv[optind], "delfence")){
	    del_fence(argc-1, argv+1);
	    exit(EXIT_FAILURE);
     }
     else if(!strcmp(argv[optind], "lsnode")){
	    list_nodes(argc-1, argv+1);
	    exit(EXIT_FAILURE);
     }
     else if(!strcmp(argv[optind], "lsfence")){
	    list_fences(argc-1, argv+1);
	    exit(EXIT_FAILURE);
     }
     else if(!strcmp(argv[optind], "create")){
	    create_skeleton(argc-1, argv+1);
	    exit(EXIT_FAILURE);
     }
     else if(!strcmp(argv[optind], "addnodeids")){
	    add_nodeids(argc-1, argv+1);
	    exit(EXIT_FAILURE);
     }

     else {
       fprintf(stderr, "Unknown command, %s.\n"
	      "Try 'ccs_tool help' for help.\n", argv[optind]);
       exit(EXIT_FAILURE);
     }

It's a bit of a bother that any automation working with these tools has 
to always parse the output - I cannot put in any sort of future-proof 
error-checking that just looks at the exit code.

Thanks,
Aravind.
