Description

When trying to upgrade a MySQL 5.1.14 database to MariaDB 10.6.4 mariadb-upgrade fails:

Phase 4/7: Running 'mysql_fix_privilege_tables'

ERROR 1178 (42000) at line 174: The storage engine for the table doesn't support nullable columns

FATAL ERROR: Upgrade failed

After this error, the database is destroyed beyond repair.

After studying the source code of mariadb-upgrade and mariadb-check for a while, I found out that the following SQL statement from mysql_fix_privilege_tables_sql.c is causing the problem:

"ALTER TABLE slow_log\n"

  "  ADD COLUMN thread_id BIGINT(21) UNSIGNED NOT NULL AFTER sql_text;\n",

If I drop the slow_log table before the upgrade everything works smoothly and the slow_log table is recreated.

Output from MySQL 5.1.14:

mysql> desc slow_log;

1 row in set (0.00 sec)

So, the table is already using the CSV storage engine and has nullable columns in MySQL.
