Probleam: Dead loop cause of keep pushing analyze tasks into job stack. When doing analyze process and generate new operators, the same analyze rule would be pushed again, so it cause dead loop. And analyze process generate new operators when trying to bound order by key and aggregate function. Solve: We need to make it throw exception before complex analyze and rewrite process, so checking whether all expressions being bound should be done twice. One is done after bounding all expression, another is done after all analyze process in case of generate new expressions and new operators. Example: Cases were put in file: regression-test/suites/nereids_p0/except/test_bound_exception.groovy # Proposed changes Issue Number: close #xxx ## Problem summary Describe your changes. ## Checklist(Required) * [ ] Does it affect the original behavior * [x] Has unit tests been added * [ ] Has document been added or modified * [ ] Does it need to update dependencies * [ ] Is this PR support rollback (If NO, please explain WHY) ## Further comments If this is a relatively large or complex change, kick off the discussion at [d...@doris.apache.org](mailto:d...@doris.apache.org) by explaining why you chose the solution you did and what alternatives you considered, etc... -- This is an automated message from the Apache Git Service.
