MDEV-32329 (patch) pushdown from having into where: Server crashes at sub_select When generating an Item_equal with a Item_ref that refers to a field outside of a subselect, remove_item_direct_ref() causes the dependency (depended_from) on the outer select to be lost, which causes trouble for code downstream that can no longer determine the scope of the Item. Not calling remove_item_direct_ref() retains the Item's dependency. Test cases from MDEV-32395 and MDEV-32329 are included. Some fixes from other developers: Monty: - Fixed wrong code in Item_equal::create_pushable_equalities() that could cause wrong item to be used if there was no matching items. Daniel Black: - Added test cases from MDEV-32329 Igor Babaev: - Provided fix for removing call to remove_item_direct_ref() in eliminate_item_equal() MDEV-32395: update_depend_map_for_order: SEGV at /mariadb-11.3.0/sql/sql_select.cc:16583 Include test cases from MDEV-32329. |

MariaDB: The innovative open source database
MariaDB was designed as a drop-in replacement of MySQL(R) with more features, new storage engines, fewer bugs, and better performance.
MariaDB is brought to you by the MariaDB Foundation and the MariaDB Corporation. Please read the CREDITS file for details about the MariaDB Foundation, and who is developing MariaDB.
MariaDB is developed by many of the original developers of MySQL who now work for the MariaDB Corporation, the MariaDB Foundation and by many people in the community.
MySQL, which is the base of MariaDB, is a product and trademark of Oracle Corporation, Inc. For a list of developers and other contributors, see the Credits appendix. You can also run 'SHOW authors' to get a list of active contributors.
A description of the MariaDB project and a manual can be found at:
https://mariadb.com/kb/en/mariadb-vs-mysql-features/
https://mariadb.com/kb/en/mariadb-versus-mysql-compatibility/
https://mariadb.com/kb/en/new-and-old-releases/
Getting the code, building it and testing it
Refer to the following guide: https://mariadb.org/get-involved/getting-started-for-developers/get-code-build-test/ which outlines how to build the source code correctly and run the MariaDB testing framework, as well as which branch to target for your contributions.
Help
More help is available from the Maria Discuss mailing list https://lists.mariadb.org/postorius/lists/discuss.lists.mariadb.org/ and MariaDB's Zulip instance, https://mariadb.zulipchat.com/
