Allow DROP TABLE `#mysql50##sql-...._.` to drop tables that were being rebuilt by ALGORITHM=INPLACE NOTE: If the server is killed after the table-rebuilding ALGORITHM=INPLACE commits inside InnoDB but before the .frm file has been replaced, then the recovery will involve something else than DROP TABLE. NOTE: If the server is killed in a true inplace ALTER TABLE commits inside InnoDB but before the .frm file has been replaced, then we are really out of luck. To properly handle that situation, we would need a transactional mysql.ddl_fixup table that directs recovery to rename or remove files. prepare_inplace_alter_table_dict(): Use the altered_table->s->table_name for generating the new_table_name. table_name_t::part_suffix: The start of the partition name suffix. table_name_t::dbend(): Return the end of the schema name. table_name_t::dblen(): Return the length of the schema name, in bytes. table_name_t::basename(): Return the name without the schema name. table_name_t::part(): Return the partition name, or NULL if none. row_drop_table_for_mysql(): Assert for #sql, not #sql-ib.

# Bug #18734396 INNODB IN-PLACE ALTER FAILURES BLOCK FUTURE ALTERS

#

# Temporary tablename will be unique. This makes sure that future

# in-place ALTERs of the same table will not be blocked due to
