Botong Huang created CALCITE-3118: ------------------------------------- Summary: VolcanoRuleCall match parent child ordinal not properly checked Key: CALCITE-3118 URL: https://issues.apache.org/jira/browse/CALCITE-3118 Project: Calcite Issue Type: Bug Reporter: Botong Huang
In VolcanoRuleCall.matchRecurse(), when ascending (child operand is matched, looking for parent operand match), we want to check that the matched parent indeed has the previously matched child RelNode as a child with the expected ordinal. However, there is a bug in this check. As a result, some incorrect parent is not skipped as expected and matched incorrectly. See unit test included in PR for a case that triggers this bug, where the same RelNode get matched for two operands at the same time. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
