Steven Talbot created CALCITE-3877: -------------------------------------- Summary: Null lowerBound/upperBond in RexWindow causes NPE in RexShuttle Key: CALCITE-3877 URL: https://issues.apache.org/jira/browse/CALCITE-3877 Project: Calcite Issue Type: Bug Reporter: Steven Talbot
Here's a test that can be dropped into RexShuttleTest.java {code:java} @Test public void handlesNullBoundsInRexWindow() { final RelBuilder builder = RelBuilder.create(RelBuilderTest.config().build()); final RexNode over = builder.getRexBuilder().makeOver( builder.getTypeFactory().createSqlType(SqlTypeName.BIGINT), SqlStdOperatorTable.ROW_NUMBER, ImmutableList.of(), ImmutableList.of(), ImmutableList.of(), null, null, true, true, true, true, true ); assertThat(over.accept(new RexShuttle()), is(over)); } {code} That will raise an NPE. Fix is to handle NULLs when doing the child accept on the RexWindowBound[s] in RexShuttle.visitWindow. -- This message was sent by Atlassian Jira (v8.3.4#803005)
