row_drop_tables_for_mysql_in_background(): Copy the table name before closing the table handle, to avoid heap-use-after-free if another thread succeeds in dropping the table before row_drop_table_for_mysql_in_background() completes the table name lookup. dict_mem_create_temporary_tablename(): With innodb_safe_truncate=ON (the default), generate a simple, unique, collision-free table name using only the id, no pseudorandom component. This is safe, because on startup, we will drop any #sql tables that might exist in InnoDB. This is a backport from 10.3. It should have been backported already as part of backporting MDEV-14717,MDEV-14585 which were prerequisites for the MDEV-13564 backup-friendly TRUNCATE TABLE. This seems to reduce the chance of table creation failures in ha_innobase::truncate(). ha_innobase::truncate(): Do not invoke close(), but instead mimic it, so that we can restore to the original table handle in case opening the truncated copy of the table failed. |
