    Problem Report Number 1128
    Submitter's Classification Test Suite problem
    State Resolved
    Resolution Rejected (REJ)
    Problem Resolution ID REJ.X.0330
    Raised 1970-01-01 08:00
    Updated 2003-03-13 08:00
    Published null
    Product Standard Internationalised System Calls and Libraries Extended V2 (UNIX 98)
    Certification Program The Open Brand certification program
    Test Suite VSU version 5.0.2
    Test Identification CAPIsockets/gethostent 5
    Problem Summary PG4U.00143 The test bed does not provide a stable host database.
    Problem Text
    The functionality being tested by this test is correct on our
    implementation, however because our network host database file is
    continually being updated, the value of VSU_HOST_CNT in tetexec.cfg,
    as determined by "vsuconfig -x", may no longer be valid by the time
    the gethostent() test is executed. In this case, the last call to
    gethostent() may succeed unexpectedly instead of indicating an end
    of file as the test is expecting. Re-executing this test directly
    after updating VSU_HOST_CNT to contain the correct value demonstrates
    the functionality is intact:

    520|1 5 28080 1 1|SPEC1170TESTSUITE CASE 5
    520|1 5 28080 1 2|Return a null pointer on a call to struct hostent
    520|1 5 28080 1 3|*gethostent(void) when the end of the database was
    520|1 5 28080 1 4|reached.

    220|1 5 0 11:31:21|PASS
    410|1 5 1 11:31:21|IC End

    In the absense of isolated network, it would be desirable if these
    tests were designed to obtain VSU_HOST_CNT at runtime.
    Test Output
    TEST CASE: gethostent

    TEST PURPOSE #5
    Return a null pointer on a call to struct hostent
    *gethostent(void) when the end of the database was
    reached.
    PREP: Call gethostent() the number of times defined by
    the configuration variable VSU_HOST_CNT
    TEST: Call gethostent() at end of file
    ERROR: gethostent succeeded unexpectedly, host = 10011cd08
    5 FAIL

    Review Response
    We recommend this request be denied.

    This is a configuration problem. The test suite documentation requires
    the user to specify a value for VSU_HOST_CNT that is accurate when the
    test suite is run, and the submitter is not doing so. We suggest the
    submitter effect a test environment is which the continual updating of the
    host database is supressed.

    Note that there is no portable way we can see to get this number other
    than static configuration, as the nature of the host database is not
    defined by the specification.
