MDEV-29481 mariadb-upgrade prints confusing statement This is a new version of the patch instead of the reverted: MDEV-28727 ALTER TABLE ALGORITHM=NOCOPY does not work after upgrade Ignore the difference in key packing flags HA_BINARY_PACK_KEY and HA_PACK_KEY during ALTER to allow ALGORITHM=INSTANT and ALGORITHM=NOCOPY in more cases. If for some reasons (e.g. due to a bug fix such as MDEV-20704) these cumulative (over all segments) flags in KEY::flags are different for the old and new table inside compare_keys_but_name(), the difference in HA_BINARY_PACK_KEY and HA_PACK_KEY in KEY::flags is not really important: MyISAM and Aria can handle such cases well: per-segment flags are stored in MYI and MAI files anyway and they are read during ha_myisam::open() ha_maria::open() time. So indexes get opened with correct per-segment flags that were calculated during the table CREATE time, no matter what the old (CREATE time) and new (ALTER TIME) per-index compression flags are, and no matter if they are equal or not. All other engine ignore key compression flags, so this change is safe for other engines as well.
