Marieke Gueye created CALCITE-5663: -------------------------------------- Summary: [TestKit] RelOptFixture does not enforce the collation Key: CALCITE-5663 URL: https://issues.apache.org/jira/browse/CALCITE-5663 Project: Calcite Issue Type: Bug Reporter: Marieke Gueye
In RelOptFixture, we currently change the traitsets to enforce EnumerableConvention.INSTANCE, however, in this instance we forget to port the collation in the traitset. ``` if (planner instanceof VolcanoPlanner) { r2 = planner.changeTraits(relBefore, relBefore.getTraitSet().replace(EnumerableConvention.INSTANCE)); } else { r2 = relBefore; } ``` The problem goes even deeper, as of now, there is no way to get access to the collation as it lives in the relRoot, and we currently only access the relNode through the `relSupplier` The consequence of this can be pretty dire as it may mean that some rules might be incorrectly tested. -- This message was sent by Atlassian Jira (v8.20.10#820010)
