      Ideally for all DBs...

      In a site with at least 1 course with at least 1 activity of each type, try (always using the current versions of each branch):

      First set:
      1) Upgrade from 19 to 22.
      2) Upgrade from 22 to 25.

      Second set:
      3) Upgrade from 22 to 23.
      4) Upgrade from 23 to 24.
      5) Upgrade from 24 to 25.

      Verify no error happen with rebuild_course_cache() involved. That's enough to pass this. Any other problem must be reported in separated issue.

      Detected upgrading one 2.4dev site to current 2.5beta:

      Debug info: ORA-00904: "SHOW_EXPANDED": invalid identifier
      SELECT id, name, display, show_expanded, intro, introformat FROM m_folder WHERE id = :o_id
      [array (
      'o_id' => '21',
      )]
      Error code: dmlreadexception

      line 429 of /mod/folder/lib.php: call to moodle_database->get_record()
      line 936 of /course/lib.php: call to folder_get_coursemodule_info()
      line 1457 of /lib/modinfolib.php: call to get_array_of_activities()
      line 1463 of /lib/db/upgrade.php: call to rebuild_course_cache()
      line 1530 of /lib/upgradelib.php: call to xmldb_main_upgrade()
      line 292 of /admin/index.php: call to upgrade_core()
      

      With the problem being the call to rebuild_course_cache() without params, aka, forcing the rebuild and trying to access to a non-existing-yet column folder->show_expanded.

      That call in upgrade code is forbidden and, alternatively, this should be used instead:

      rebuild_course_cache(0, true);
      

      because it's a safe alternative not using the cm api for regenerating the information but just a pair of raw sql statements.

      So this is about to change all the incorrect uses to correct ones, to avoid upgrade problems here and there.

      Ciao
