    Problem Report Number 1546
    Submitter's Classification Test Suite problem
    State Resolved
    Resolution Test Suite Deficiency (TSD)
    Problem Resolution ID TSD.X.0828
    Raised 2000-08-28 08:00
    Updated 2003-03-13 08:00
    Published 2000-09-18 08:00
    Product Standard Internationalised System Calls and Libraries Extended V2 (UNIX 98)
    Certification Program The Open Brand certification program
    Test Suite VSU version 5.0.4
    Test Identification BASE/setpriority 10
    Problem Summary TSD4U.00289 These tests may fail on systems which support additional values for the "which" argument of getpriority() and setpriority()
    Problem Text
    The specification for getpriority and setpriority states

    "The which argument may be one of the following values:
    PRIO_PROCESS, PRIO_PGRP, or PRIO_USER..."

    The use of "may" rather than "must" along with the header
    specification for sys/resource.h and the X/Open namespace rules
    for sys/resource.h (section 2.2.1) allow that an implementation
    may extend these PRIO_ macros.

    The getpriority and setpriority tests are failing because they do
    not take into account that an implementation may have extended the
    PRIO_ macros defined by the specification.

    More specifically, the tests are assuming only the above mentioned
    PRIO_ values (with numeric values 0, 1, and 2), choosing a assumed
    invalid value one higher (numeric value 3), and failing when the
    value is actually recognized by set/getpriority as valid.

    NOTE: location of tests in VSU 5.1.1 is not the same as listed
    above (which is for 5.0.4A), they are located in CAPI.os/procenv.
    Test Output
    TEST CASE: getpriority

    TEST PURPOSE #8
    EINVAL in errno and return -1 on a call to int
    getpriority(int which, id_t who) when which is invalid.
    PREP: Obtain a numeric value 'which' not equal to
    PRIO_PROCESS, PRIO_PGRP or PRIO_USER
    PREP: Obtain the process ID of the current process 'pid'
    TEST: getpriority(which, pid) returns -1 and sets
    errno to EINVAL
    ERROR: getpriority set errno to an invalid value
    Expected: 22(EINVAL) Received: 3(ESRCH - No such process)
    8 FAIL

    TEST CASE: setpriority

    TEST PURPOSE #10
    EINVAL in errno and return -1 on a call to int
    setpriority(int which, id_t who, int priority) when
    which is invalid.
    PREP: Obtain a numeric value 'which' not equal to
    PRIO_PROCESS, PRIO_PGRP or PRIO_USER
    PREP: Obtain the process ID and the current priority
    of the current process
    PREP: Obtain a valid numeric value for priority
    TEST: setpriority(which, pid, priority) returns -1
    and sets errno to EINVAL
    ERROR: setpriority set errno to an invalid value
    Expected: 22(EINVAL) Received: 3(ESRCH - No such process)
    10 FAIL

    Review Information

    Review Type TSMA Review
    Start Date null
    Completed null
    Status Complete
    Review Recommendation No Resolution Given
    Review Response
    This is accepted as a fault in the test suite.

    The request had an invalid VR field of "VSU 5.0.4A, VSU 5.1.1". This
    has been changed to "VSU 5.0.4A" since that is the test suite version
    which matches the supplied test output. If a TSD for VSU5.1.1 is also
    required, then a separate interpretation request for that version
    needs to be submitted.

    Review Type SA Review
    Start Date null
    Completed null
    Status Complete
    Review Resolution Test Suite Deficiency (TSD)
    Review Conclusion
    This is an agreed Test Suite Deficiency. Please note this applies only
    to VSU 5.0.4A as advised by the consultant.
