.. share->last_version' failed in myisam/mi_open.c:67: test_if_reopen During the RENAME operation since the renamed temporary table is also opened and added to myisam_open_list/maria_open_list, resetting the last_version at the end of operation (HA_EXTRA_PREPARE_FOR_RENAME) will cause an assertion failure when a subsequent query tries to open an additional temporary table instance and thus attempts to reuse it from the open table list. This commit fixes the issue by skipping flush/close operations executed toward the end of ALTER for temporary tables. It also enables a shortcut for simple ALTERs (like rename, disable/enable keys) on temporary tables. As safety checks, added some assertions at code points that should not be hit for temporary tables.
