# WL#7957: MDL FOR TABLESPACES
# ============================
#
# We have the following tablespace DDL operations that acquire
# exclusive MDL locks on tablespaces:
#
#   CREATE, ALTER and DROP TABLESPACE
#
# Then, we have the following non-tablespace related DDL
# operations that acquire intention exclusive locks on
# tablespaces:
#
#   CREATE, ALTER, RENAME, TRUNCATE, LOCK, DROP TABLE
#
# and
#
#   CREATE, DROP INDEX
#
# Below are test cases to verify that:
#
# 1. We can *not* run DDL statements manipulating the same
#    tablespace concurrently.
# 2. We can run different DDL statements manipulating different
#    tablespaces concurrently.
# 3. We can run different DDL statements accessing different
#    tables in the same  tablespace concurrently.
# 4. We can *not* run DDL statements on tables in a given
#    tablespace concurrently with DDL operations on the
#    same tablespace.
# 5. Verify that dropping a schema with tables in various
#    tablespaces cannot run concurrentlty with dropping the
#    tablespaces.
# 6. Verify that tablespace IX locks are not acquired in
#    the context of 'FLUSH TABLE WITH READ LOCK',
#    'FLUSH TABLE FOR EXPORT' or 'LOCK TABLE READ'.
# 7. Verify that statements 'FLUSH TABLE WITH READ LOCK',
#    'FLUSH TABLE FOR EXPORT' and 'LOCK TABLE READ'
#    can run concurrently with DDL operations on the
#    tablespace.
# 8. Verify that tablespace IX locks are acquired in
#    the context of 'LOCK TABLE WRITE'.
# 9. Verify that table DML (e.g. SELECT ... FOR UPDATE)
#    can run concurrently with DDL on the tablespace.
# 10. Verify that MDL with prepared statements works as
#     expected, using a prepared ALTER TABLE.
# 11. Verify that a non-empty tablespace cannot be dropped.
# 12. Verify that the tablespace name length is checked
#     properly.
# 13. Extend test coverage:
#       i) Run tablespace DDL within lock tables mode.
#      ii) Run tablespace DDL when the global read lock
#          is taken.
#     iii) Provoke timeout for table DDL waiting for
#          tablespace MDL IX lock.
#      iv) Provoke timeout for tablespace DDL waiting for
#          tablespace MDL X lock.
# 14. Verify that CREATE TABLE ... LIKE statements are
#     handled correctly, both with and without source
#     tables in general tablespaces.
# 15. Verify that explicit invalid tablespace names make
#     table related DDL be rejected. Verify that implicit
#     invalid tablespace names (e.g., present in an .FRM
#     file from a previous MySQL version) are ignored.
# 16. Verify correct P_S information.
