Subject [GitHub] incubator-hawq pull request: QE core dumped when report "Resume in...
Date Tue, 22 Mar 2016 09:19:34 GMT
GitHub user liming01 opened a pull request:

    https://github.com/apache/incubator-hawq/pull/485

    QE core dumped when report "Resume interrupt holdoff count is bad (0)…

    … (xact.c:2907)"
    
    The root cause is: 
    AT AbortTransaction(),  we will disable interrupt processing by calling  "HOLD_INTERRUPTS();"
and "RESUME_INTERRUPTS();", these 2 functions will change "InterruptHoldoffCount" to indicate
that we are in such a section. When in such a section, we can't report error, because it will
set  InterruptHoldoffCount to 0. 
    
    On the other side, from the user demand, when transaction abort, we can't report error
if temp file cannot be deleted, we need to just report warning.
