    Problem Report Number 1540
    Submitter's Classification Test Suite problem
    State Resolved
    Resolution Test Suite Deficiency (TSD)
    Problem Resolution ID TSD.X.0822
    Raised 2000-08-11 08:00
    Updated 2003-03-13 08:00
    Published 2000-08-21 08:00
    Product Standard Internationalised System Calls and Libraries Extended V2 (UNIX 98)
    Certification Program The Open Brand certification program
    Test Suite VSU version 5.1.1
    Test Identification CAPI.os/ioprim/read 17
    Problem Summary TSD4U.00283 These tests assume that closing the write-side of the stream reflector causes a hangup on the read-side. This is true for a pipe but fails when the tests are run using pseudo-terminals.
    Problem Text
    This interpretation request if for the following assertions:
    tset/CAPI.os/ioprim/read/T.read 17
    tset/CAPI.os/ioprim/readv/T.readv 39
    tset/CAPI.os/ioprim/readv/T.readv 40


    These failures also exists in the same tests in VSU 5.0.4.

    These failures occur because the tests expect the close on fildes[1](which
    is the slave pty) to generate a hangup. But the XSH5 page 135
    states the following:

    "If fildes refers to the slave side of a STREAMS-based psuedo-terminal,
    a zero length message may be sent to the master."

    This does not state a M_HANGUP message is required to be sent up the stream.
    Test Output
    ************************************************************************
    /tset/CAPI.os/ioprim/read/T.read 17 Failed

    Test Description:
    Base Required Conformance
    A call to ssize_t read(int fildes, void *buf, size_t nbyte) when
    fildes refers to a STREAMS file and a hangup occurred on the STREAM
    and the STREAM head read queue is empty shall return 0.

    Test Information:
    PREP: Ignore SIGPOLL, SIGHUP, and SIGPIPE signals
    PREP: Set O_NONBLOCK on read end of STREAM
    PREP: Generate hangup
    TEST: Read returns 0
    ERROR: read returned -1

    ************************************************************************

    ************************************************************************
    /tset/CAPI.os/ioprim/readv/T.readv 39 Failed

    Test Description:
    Base Required Conformance
    A call to ssize_t readv(int fildes, const struct iovec *iov, int
    iovcnt) when fildes refers to a STREAMS file and a hangup occurs on
    the STREAM shall continue to operate normally until the STREAM head
    read queue is empty.

    Test Information:
    PREP: Create a pipe
    PREP: Determine if pipe is a stream
    INFO: Pipes are not STREAMS based on this implementation.
    PREP: Ignore SIGPOLL, SIGHUP, and SIGPIPE signals
    PREP: Set O_NONBLOCK on read end of STREAM
    PREP: Set O_NONBLOCK on write end of STREAM
    PREP: Put some messages on the STREAM
    PREP: Hangup write end of STREAM
    ERROR: Test took longer than 600 seconds: presuming
    function is hung and terminating test
