Haisheng Yuan created CALCITE-3676: -------------------------------------- Summary: VolcanoPlanner. dumpGraphviz should handle exception gracefully Key: CALCITE-3676 URL: https://issues.apache.org/jira/browse/CALCITE-3676 Project: Calcite Issue Type: Bug Components: core Reporter: Haisheng Yuan
In case VolcanoPlanner can't generate plan due to some RelSubset doesn't have best rel, it will dump the sets and Graphviz. Since there is error during planning, we want to see the sets in the exception message, but when dumping Graphviz, it might encounter another exception (we can't guarantee all the sets and subsets are correctly generated for Graphviz), causing failure to dump Sets info, which is rather helpful in production system. {code:java} Caused by: java.lang.AssertionError at org.apache.calcite.util.PartiallyOrderedSet.findParentsChildren(PartiallyOrderedSet.java:318) at org.apache.calcite.util.PartiallyOrderedSet.findParents(PartiallyOrderedSet.java:308) at org.apache.calcite.util.PartiallyOrderedSet.add(PartiallyOrderedSet.java:226) at org.apache.calcite.plan.volcano.VolcanoPlanner.dumpGraphviz(VolcanoPlanner.java:1320) at org.apache.calcite.plan.volcano.VolcanoPlanner.dump(VolcanoPlanner.java:1194) at org.apache.calcite.plan.volcano.RelSubset$CheapestPlanReplacer.visit(RelSubset.java:606) at org.apache.calcite.plan.volcano.RelSubset.buildCheapestPlan(RelSubset.java:307) at org.apache.calcite.plan.volcano.VolcanoPlanner.findBestExp(VolcanoPlanner.java:649) {code} -- This message was sent by Atlassian Jira (v8.3.4#803005)
