A label statement needs to be followed by at least
one primary expression.  If built without
WITH_PARTITION_STORAGE_ENGINE set, the block would 
be empty.

Added ';' as a dummy statement to fix it.

                        with open HANDLER

This patch changes the code for table renames to not drop metadata
locks. Since table renames are done as a part of ALTER DATABASE ...
UPGRADE, dropping metadata locks in the middle of execution can
result in wrong binlog order since it means that no locks are held
when the binlog is written to.

The RENAME TABLE statement is unafffected since it auto commits and
therefore already drops metadata locks at the end of execution.

This patch also reverts the regression test for Bug#48940 back to
its original version. The test was temporarily changed due to the
issue mentioned above.

Remove acquisition of LOCK_open around file system operations,
since such operations are now protected by metadata locks.
Rework table discovery algorithm to not require LOCK_open.

No new tests added since all MDL locking operations are covered
in lock.test and mdl_sync.test, and as long as these tests
pass despite the increased concurrency, consistency must be
unaffected.

mysql-test/t/disabled.def:
  Disable NDB tests due to Bug#55799.
sql/datadict.cc:
  No longer necessary to protect ha_create_table() with

sql/handler.cc:
  Implement ha_check_if_table_exists().
  @todo: some engines provide ha_table_exists_in_engine()

  Remove get_table_share_with_create(), we should
  not attempt to create a table under LOCK_open.
  Introduce get_table_share_with_discover() instead,
  which would request a back off action if the table
  exists in engine.
  Remove acquisition of LOCK_open for 
  data dictionary operations, such as check_if_table_exists().
  Do not use get_table_share_with_create/discover for views,
  where it's not needed.

Post-merge fix: add missing comma.

Post-merge fix: remove --with-debug=full, it was only used for safemalloc.

BUILD/compile-pentium-mysqlfs-debug:
  Remove build script for a feature that is long gone.

FLUSH TABLES <list> WITH READ LOCK are incompatible" to
be pushed as separate patch.

Replaced thread state name "Waiting for table", which was
used by threads waiting for a metadata lock or table flush, 
with a set of names which better reflect types of resources
being waited for.

Also replaced "Table lock" thread state name, which was used 
by threads waiting on thr_lock.c table level lock, with more
elaborate "Waiting for table level lock", to make it 
more consistent with other thread state names.

Updated test cases and their results according to these 
changes.

Fixed sys_vars.query_cache_wlock_invalidate_func test to not
to wait for timeout of wait_condition.inc script.

  changes to test which introduced timeout and replaced waiting
  condition with a more appropriate one.

mysys/thr_lock.c:
  Replaced "Table lock" thread state name, which was used by

sql/mdl.cc:
  Replaced thread state name "Waiting for table", which was
  used by threads waiting for a metadata lock or table flush, 
  with a set of names which better reflect types of resources

  To implement this:
  - Adjusted MDL_wait::timed_wait() to take thread state name
    as parameter.
  - Introduced method of MDL_key class which allows to get
    thread state name to be used while waiting for resource
    corresponding to the key and changed code to use it.
    Added array translating namespaces to thread state names
    as part of this change.

******
This patch fixes the following bugs:
  - Bug#5889: Exit handler for a warning doesn't hide the warning in
    trigger
  - Bug#9857: Stored procedures: handler for sqlwarning ignored
  - Bug#23032: Handlers declared in a SP do not handle warnings generated
    in sub-SP
  - Bug#36185: Incorrect precedence for warning and exception handlers

The problem was in the way warnings/errors during stored routine execution
were handled. Prior to this patch the logic was as follows:

  - when a warning/an error happens: if we're executing a stored routine,
    and there is a handler for that warning/error, remember the handler,
    ignore the warning/error and continue execution.

  - after a stored routine instruction is executed: check for a remembered
    handler and activate one (if any).

This logic caused several problems:

  - if one instruction generates several warnings (errors) it's impossible
    to choose the right handler -- a handler for the first generated
    condition was chosen and remembered for activation.

  - mess with handling conditions in scopes different from the current one.

  - not putting generated warnings/errors into Warning Info (Diagnostic
    Area) is against The Standard.

The patch changes the logic as follows:

  - Diagnostic Area is cleared on the beginning of each statement that
    either is able to generate warnings, or is able to work with tables.

  - at the end of a stored routine instruction, Diagnostic Area is left
    intact.

  - Diagnostic Area is checked after each stored routine instruction. If
    an instruction generates several condition, it's now possible to take a
    look at all of them and determine an appropriate handler.

the precursor patch for Bug#52044.
When passing the TABLE instance for invalidation to the
query cache, we didn't always have a valid share
(in case of error).
Make sure we invalidate the table using TABLE_LIST, not
TABLE, object.

sql/sql_table.cc:
  Make sure we invalidate the table using TABLE_LIST, not
  TABLE, object.

Problem: The original patch didn't compile on debug_werror
due to wrong format in printf("%d") for size_t variables.

Fix: Adding cast to (int).

/*![:version:] Query Code */, where [:version:] is a sequence of 5 
digits representing the mysql server version(e.g /*!50200 ... */),
is a special comment that the query in it can be executed on those 
servers whose versions are larger than the version appearing in the 
comment. It leads to a security issue when slave's version is larger 
than master's. A malicious user can improve his privileges on slaves. 
Because slave SQL thread is running with SUPER privileges, so it can
execute queries that he/she does not have privileges on master.

This bug is fixed with the logic below: 
- To replace '!' with ' ' in the magic comments which are not applied on
  master. So they become common comments and will not be applied on slave.

- Example:
  'INSERT INTO t1 VALUES (1) /*!10000, (2)*/ /*!99999 ,(3)*/
  will be binlogged as
  'INSERT INTO t1 VALUES (1) /*!10000, (2)*/ /* 99999 ,(3)*/

            DELETE statement

Single-table delete ordered by a field that has a hash-type index
may cause an assertion failure or a crash.

An optimization added by the fix for the bug 36569 forced the
optimizer to use ORDER BY-compatible indices when applicable.

However, the existence of unsorted indices (HASH index algorithm
for some engines such as MEMORY/HEAP, NDB) was ignored.

The test_if_order_by_key function has been modified to skip
unsorted indices.

The failure was introduced by a precursor patch for the

When opening tables for GRANT statement
to check that subject columns exist,
mysql_table_grant() would try to lock the
tables, and thus start a transaction.
This was unnecessary and lead to an assert.


sql/sql_acl.cc:
  Use open_normal_and_derived_tables() rather than
  open_and_lock_tables() to avoid an assert
  that no transaction is started in GRANT statement.
