Aleksey Midenkov 24fff8267d MDEV-25292 gcol.gcol_bugfixes --ps fix
Related to MDEV-24176.

1. vcol_fix_expr() generates new tree changes:
Type_std_attributes::agg_item_set_converter() does change_item_tree().

The changes are allocated on expr_arena (via Vcol_expr_context as per
MDEV-24176).

2. vcol_cleanup_expr() doesn't remove these changes (can be a bug of
Type_std_attributes or per design).

3. Atomic CREATE OR REPLACE renames old table to backup
(finalize_atomic_replace()). It does that via
rename_table_and_triggers() and that closes table share and releases
expr_arena root. Hence now we have Item corpses in thd->change_list.

4. PS cleanup phase tries to rollback thd->change_list and accesses
already freed item corpses.

The fix saves and restores change_list on
vcol_fix_expr()/vcol_cleanup_expr().

MariaDB: The open source relational 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.

Live QA for beginner contributors

MariaDB has a dedicated time each week when we answer new contributor questions live on Zulip. From 8:00 to 10:00 UTC on Mondays, and 10:00 to 12:00 UTC on Thursdays, anyone can ask any questions theyd like, and a live developer will be available to assist.

New contributors can ask questions any time, but we will provide immediate feedback during that interval.
