# Bug#20676000 FAILING MDL TABLESPACE ASSERTION FOR ALTER NDB TABLE IN UNIREG.CC:263
#
# For mysql versions before 50120, NDB stored the tablespace names only
# in the NDB dictionary. Thus, in order to acquire an MDL lock on the
# tablespace name, the server has to get the name from the engine rather
# than the .FRM file in this case. This test verifies that restoring an
# NDB table with version < 50120, followed by various SQL commands,
# will lock the tablespace name properly.
#
# We do various SQL statements in a separate connection, and verify that
# each statement grabs an MDL lock on the tablespace name. We create
# a new connection each time to verify that this works even if getting
# the tablespace name from NDB is the first function in NDB being invoked
# for the given connection. Between each SQL statement that is tested,
# we must drop the restored database items and restore over again,
# because the DDL statements will write the meta data according to the
# target mysql version, and not the backed up version < 50120 (which is
# what we want to test in this context).
