[Commits] c8613d7: MDEV-30706 Different results of selects from view and CTE with same definition

revision-id: c8613d7ddf380eb9eb9a2e070e55dbe7ebaf37cf (mariadb-10.4.28-31-gc8613d7) parent(s): 476b24d084e7e717310155bb986eb086d3c1e1a6 author: Igor Babaev committer: Igor Babaev timestamp: 2023-03-01 22:49:27 -0800 message: MDEV-30706 Different results of selects from view and CTE with same definition MDEV-30668 Set function aggregated in outer select used in view definition This patch fixes two bugs concerning views whose specifications contain subqueries with set functions aggregated in outer selects. Due to the first bug those such views that have implicit grouping were considered as mergeable. This led to wrong result sets for selects from these views. Due to the second bug the aggregation select was determined incorrectly and this led to bogus error messages. The patch added several test cases for these two bugs and for four other duplicate bugs. The patch also enables view-protocol for many other test cases.
