    ****************************************************************
    * PROBLEM DESCRIPTION: An MQGET on a shared queue can succeed  *
    *                      if the length of the message plus its   *
    *                      header exceeds the length of the        *
    *                      getter's buffer. It should have failed  *
    *                      with MQRC_TRUNCATED_MSG_FAILED if       *
    *                      MQGMO_ACCEPT_TRUNCATED_MSG is not       *
    *                      specified.                              *
    *                      An FFST may be produced by              *
    *                      rstSendAsyncMessage when client code    *
    *                      detects the length error.               *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    CSQIMGES doesn't detect that the message length plus the
    header (e.g. RFH2) exceeds the getter's buffer, and as a
    result fails to issue a MQRC_TRUNCATED_MSG_FAILED.
    Also, if an XQH is included when a message is put on a
    transmission queue, the length of the XQH is counted twice
    which may mean that the MQRC_TRUNCATED_MSG_FAILED is issued
    even though the getter's buffer is sufficiently large.
    

Problem conclusion

  • CSQIMGES has been changed to correctly calculate the message
    length when headers are included.
