Zoltan>...because unfortunately this new patch still contains an bug. Could I please correct you a bit? The patch did solve the issue that is represented in the issue description. The patch did pass all the tests you had by that moment.
So "still contains a bug" is more like "there are uncovered cases". Zoltan>* I've submitted a patch to disable this oversimplification because that seemed to be the right move to me. That is the culprit. Your analysis was too pessimistic, so you decided to remove a feature rather than implement a bug fix. There are cases when it is safer to just remove half-backed feature, however 2327 is not of that kind. >CALCITE-2271 something similar happened...Alexey Makhmutov Initial analysis by Alexey was not right, so he implemented a wrong solution. That happens when people try to fix unfamiliar codebases. Vladimir
