    Problem Report Number 1075
    Submitter's Classification Test Suite problem
    State Resolved
    Resolution Test Suite Deficiency (TSD)
    Problem Resolution ID TSD.X.0531
    Raised 1970-01-01 08:00
    Updated 2003-03-13 08:00
    Published 1999-01-28 08:00
    Product Standard Internationalised System Calls and Libraries Extended V2 (UNIX 98)
    Certification Program The Open Brand certification program
    Test Suite VSRT version 5.0.2
    Test Identification rt.os/aio/aio_read 12
    Problem Summary TSD4R.00009 This test may fail on some implementations as it uses a zero-byte transfer, which may be considered to have succeed.
    Problem Text

    This request addresses the following results:

    /tset/rt.os/aio/aio_read/T.aio_read 12 Failed
    /tset/rt.os/aio/aio_write/T.aio_write 13 Failed

    This request addresses only the failures in the "file" cases, not those
    associated with pipes or pty's.

    In each case, the suite is starting a zero-byte aio operation with
    aio_offset set to -1, expecting the implementation to detect the invalid
    offset, return -1, and set errno to EINVAL.

    Our implementation returns 0 in each case to reflect the successful completion
    of a zero-byte asynchronous transfer.

    Note that the similar test in lio_listio{37} specifies a single-byte
    transfer and passes.

    Also note that this behavior of aio_read and aio_write is aligned with
    that of pread and pwrite.
    Test Output
    ************************************************************************
    /tset/rt.os/aio/aio_read/T.aio_read 12 Failed

    Test Description:
    If _POSIX_ASYNCHRONOUS_IO is defined or the implementation supports
    the aio_read() function as described in System Interfaces and Headers,
    Issue 5:
    When the offset implied by aiocbp->aio_offset would be invalid,
    either:
    the aio_read() function shall return -1 and set errno to EINVAL
    or
    the return status of the asynchronous operation shall be set to -1
    and its error status shall be set to EINVAL.

    Test Information:
    > test with file
    For offset -1, request did not fail immediately and aio_error returned 0
    (NO ERROR), expected EINVAL
    For offset -1, request did not fail immediately and aio_return returned
    0, expected -1
    > test with pipe
    For offset -1, request did not fail immediately and aio_error returned 0
    (NO ERROR), expected EINVAL
    For offset -1, request did not fail immediately and aio_return returned
    0, expected -1
    > test with pty
    For offset -1, request did not fail immediately and aio_error returned 0
    (NO ERROR), expected EINVAL
    For offset -1, request did not fail immediately and aio_return returned
    0, expected -1
    > test with tty
    tty testing not configured

    /tset/rt.os/aio/aio_write/T.aio_write 13 Failed

    Test Description:
    If _POSIX_ASYNCHRONOUS_IO is defined or the implementation supports
    the aio_write() function as described in System Interfaces and
    Headers, Issue 5:
    When the offset implied by aiocbp->aio_offset would be invalid,
    either:
    the aio_write() function shall return -1 and set errno to EINVAL
    or
    the return status of the asynchronous operation shall be set to -1
    and its error status shall be set to EINVAL.
