[jira] [Created] (ARROW-3487) simplify NULL_IF_NULL functions that
can return errors
Pindikura Ravindra created ARROW-3487:
-----------------------------------------
Summary: simplify NULL_IF_NULL functions that can return errors
Key: ARROW-3487
URL: https://issues.apache.org/jira/browse/ARROW-3487
Project: Apache Arrow
Issue Type: Task
Components: Gandiva
Reporter: Pindikura Ravindra
NULL_IF_NULL functions that can return errors eg. divide currently look at the validity bits in each function (to avoid returning spurious errors).
{code:java}
divide(TYPE in1, boolean is_valid1, TYPE in2, boolean is_valid2, ..) {
if (!is_valid1 || !is_valid2) {
return 0;
}
if (in2 == 0) { /* set error */ }
}
{code}
This validity check is duplicated for multiple functions and should be moved to the common layer (for all NULL_IF_NULL functions that can return error).
