    Problem Report Number 1279
    Submitter's Classification Test Suite problem
    State Resolved
    Resolution Test Suite Deficiency (TSD)
    Problem Resolution ID TSD.X.0561
    Raised 1970-01-01 08:00
    Updated 2003-03-13 08:00
    Published 1998-09-18 08:00
    Product Standard Internationalised System Calls and Libraries Extended V2 (UNIX 98)
    Certification Program The Open Brand certification program
    Test Suite VSU version 5.0.2
    Test Identification base/writev 34
    Problem Summary TSD4U.00257 This test may fail if the default output mode of the terminal includes mapping of NL to CR-NL (ONLCR) and a NL appears in databuf.
    Problem Text

    The test is failing because the buffer databuf is not being initialized
    correctly. On line 155 of fprintv34.c, we have:

    memset(databuf, 0, sizeof(databuf));

    sizeof(databuf) is the size of the pointer, not the buffer. The program
    works correctly when the buffer is initialized with:

    memset(databuf, 0, max_size*2);

    immediately after the malloc().

    The uninitialized buffer caused failures when line feeds therein were
    expanded to CR/LFs.
    Test Output

    TEST CASE: writev

    TEST PURPOSE #34
    A call to ssize_t writev(int fildes, const struct
    iovec *iov, int iovcnt) when fildes refers to a
    STREAMS file, the number of bytes requested does not
    fall within the maximum and minimum write size defined
    by the top-most STREAM module and the minimum write
    size is 0 shall break the buffer into maximum size
    segments prior to sending the data downstream.
    PREP: Read VSU_STREAMS_MAX_DATA_SIZE configuration
    PREP: Allocate big enough buffer
    PREP: Open master pseudo tty
    PREP: Determine if pseudo tty is a stream
    PREP: Open slave side of pseudo tty
    PREP: Fork a child to read data
    TEST: Write 2 * STREAMS_MAX_DATA_SIZE bytes of data
    ERROR: Message was not broken up
    34 FAIL
