Michael Mior created CALCITE-2644:
-------------------------------------
Summary: isAlwaysTrue broken for IS FALSE
Key: CALCITE-2644
URL: https://issues.apache.org/jira/browse/CALCITE-2644
Project: Calcite
Issue Type: Bug
Components: core
Affects Versions: 1.17.0
Reporter: Michael Mior
Assignee: Michael Mior
This came up in the fuzz test added by [~vlsi]. In RexCall#isAlwaysTrue, the
return value for IS FALSE is the result of checking isAlwaysTrue for the
operand. Similarly, the behaviour seems to also be correct for IS NOT FALSE and
IS NOT TRUE. Could someone take a quick look and tell me if I'm missing
something?
