    Problem Report Number 1125
    Submitter's Classification Test Suite problem
    State Resolved

    Product Standard Internationalised Terminal Interfaces
    Certification Program The Open Brand certification program

    Test Identification xcurses/restartterm 1
    Problem Summary PG4U.00146 The implementation is returning -1 for an empty string capability.
    Problem Text

    Here is the failing code fragment:

    tet_infoline("TEST: String capabilities are initialized");
    if (strcmp(tigetstr("sc"), "") != 0){
    sprintf(ebuf, "ERROR: Expected save_cursor = \"\", is \"%s\"",
    tigetstr("sc"));

    The test is assuming that tigetstr("sc") will return a null string when
    the terminal does not have the "sc" capability. But according to Curses
    Interface, 4.2, p. 196, tigetstr() should return (char *)-1 here, as
    our implementation does. strcmp() fails with a segmentation violation on
    (char *)-1.

    Review Response
    We recommend this request be refused.

    The specification says tigetstr will return (char *)-1 only if capname
    is not a defined string capability, however sc is a defined string
    capability in the specification. Thus the implementation is non-conforming
    in indicating an error for it. Rather, the capability is valid but simply
    empty here and thus the test is correct as written in expecting an empty
    string as the value for it. This is standard practice in order to allow
    application portability across terminals with varied sets of capabilities.
