Diagnostics_area::set_ok_status on DROP FUNCTION
This assert tests that the server is not trying to send "ok" to
the client if an error has occured during statement processing.
In this case, the assert was triggered by lock timeout errors when
accessing system tables to do an implicit REVOKE after executing
DROP FUNCTION/PROCEDURE. In practice, this was only likely to
happen with very low values for "lock_wait_timeout" (in the bug report
1 second was used). These errors were ignored and the server tried
to send "ok" to the client, triggering the assert.
The patch for Bug#45225 introduced lock timeouts for metadata locks.
This made it possible to get timeouts when accessing system tables.
Note that a followup patch for Bug#45225 pushed after this
bug was reported, changed accessing of system tables such
that the user-supplied timeout value is ignored and the maximum
timeout value is used instead. This exact bug was therefore
only noticeable in the period between the initial Bug#45225 patch
and the followup patch.
However, the same problem could occur for any errors during revoking
of privileges - not just timeouts. This patch fixes the problem by
making sure that any errors during revoking of privileges are
reported to the client.
Test case added to sp-destruct.test. Since the original bug is not
reproducable now that system tables are accessed using a a long
timeout value, this test instead calls DROP FUNCTION with a grant
system table missing.

Extend and implement the grammar that allows to FLUSH WITH READ LOCK
a list of tables, rather than all of them.
Incompatible grammar change:
Previously one could perform FLUSH TABLES, HOSTS, PRIVILEGES in a single
statement.
After this change, FLUSH TABLES must always be alone on the list.
Judging by the test suite, however, the old extended syntax
was never or very rarely used.
The new statement requires RELOAD ACL global privilege and
LOCK_TABLES_ACL | SELECT_ACL on individual tables.
In other words, it's an atomic combination of LOCK TALBES <list> READ
and FLUSH TABLES <list>, and requires respective privileges.
For additional information about the semantics, please

Attempts to execute RESET statements within a transaction that
had acquired metadata locks, led to an assertion failure on
debug servers. This bug didn't cause any problems on release
builds.
The triggered assert is designed to check that caches are not
flushed or reset while having active transactions. It is triggered
if acquired metadata locks exist that are not from LOCK TABLE or
HANDLER statements.
In this case it was triggered by RESET QUERY CACHE while having
an active transaction that had acquired locks. The reason the
assertion was triggered, was that RESET statements, unlike the
similar FLUSH statements, was not causing an implicit commit.
This patch fixes the problem by making sure RESET statements
commit the current transaction before executing. The commit
causes acquired metadata locks to be released, preventing the
assertion from being triggered.
Incompatible change: This patch changes RESET statements so
that they cause an implicit commit.
Test case added to query_cache.test.

This patch prevents system threads and system table accesses from
using user-specified values for "lock_wait_timeout". Instead all
such accesses are done using the default value (1 year).
This prevents background tasks (such as replication, events,
accessing stored function definitions, logging, reading time-zone
information, etc.) from failing in cases where the global value
of "lock_wait_timeout" is set very low.
The patch also simplifies the open tables API. Rather than adding
another convenience function for opening and locking system tables,
this patch removes most of the existing convenience functions for
open_and_lock_tables_derived(). Before, open_and_lock_tables() was
a convenience function that enforced derived tables handling, while
open_and_lock_tables_derived() was the main function where derived
tables handling was optional. Now, this convencience function is
gone and the main function is renamed to open_and_lock_tables().
No test case added as it would have required the use of --sleep to
check that system threads and system tables have a different timeout
value from the user-specified "lock_wait_timeout" system variable.

It appears that stack overflow checks for recusrive stored procedure
calls, that run in the normal server, did not work in embedded and were
dummified with preprocessor magic( #ifndef EMBEDDED_SERVER ).
The fix is to remove ifdefs, there is no reason not to run overflow checks
and crash in deeply recursive calls.
Note: Start of the stack (thd->thread_stack variable) in embedded is not
necessarily exact but stil provides the best guess. Unless the caller of
mysql_read_connect() is already deep in the stack, thd->thread_stack
variable should approximate stack start address well.

Server was aborted due to assertion failure when one tried to
execute statement requiring prelocking (i.e. firing triggers
or using stored functions) while having open HANDLERs.
The problem was that THD::enter_locked_tables_mode() method
which was called at the beginning of execution of prelocked
statement assumed there are no open HANDLERs. It had to do
so because corresponding THD::leave_locked_tables_mode()
method was unable to properly restore MDL sentinel when
leaving LOCK TABLES/prelocked mode in the presence of open
HANDLERs.
This patch solves this problem by changing the latter method
to properly restore MDL sentinel and thus removing need for
this assumption. As a side-effect, it lifts unjustified
limitation by allowing to keep HANDLERs open when entering
LOCK TABLES mode.

Concurrent execution of a multi-DELETE statement and ALTER
TABLE statement which affected one of the tables used in
the multi-DELETE sometimes led to deadlock.
Similar deadlocks might have occured when one performed
INSERT/UPDATE/DELETE on a view and concurrently executed
ALTER TABLE for the view's underlying table, or when one
concurrently executed TRUNCATE TABLE for InnoDB table and
ALTER TABLE for the same table.
These deadlocks were caused by a discrepancy between types of
metadata and thr_lock.cc locks acquired by those statements.
What happened was that multi-DELETE/TRUNCATE/DML-through-the-
view statement in the first connection acquired SR lock on a
table, then ALTER TABLE would come in in the second connection
and acquire SNW metadata lock and TL_WRITE_ALLOW_READ
thr_lock.c lock and then would start waiting for the first
connection during lock upgrade. After that the statement in
the first connection would try to acquire TL_WRITE lock on
table and would start waiting for the second connection,
creating a deadlock.
This patch solves this problem by ensuring that we acquire
SW metadata lock in all cases in which we acquiring write
thr_lock.c lock. This guarantees that deadlocks like the
one described above won't occur since all lock conflicts
in such situation are resolved within MDL subsystem.
This patch also adds assert which should guarantee that
such situations won't arise in future.

sql/lock.cc:
Added assert that enforces that when we are locking
a non-temporary table we have an appropriate type of
metadata lock on this table.
sql/mysql_priv.h:
Added separate flag for open_tables() to be able specify that
SH metadata locks on table to be open should be acquired.
We can no longer use MYSQL_LOCK_IGNORE_FLUSH flag for this
as in addition to use in I_S implementation it is also used
for opening system tables. Since in the latter case we also
acquire thr_lock.c locks using SH metadata lock in it instead
of SR or SW locks may lead to deadlock.
sql/sql_base.cc:
When opening tables don't interpret MYSQL_LOCK_IGNORE_FLUSH
flag as request to acquire SH metadata locks. This flag is
also used for opening system tables for which we also take
thr_lock.c locks and thus proper metadata lock to take in
this case is SR or SW lock (otherwise deadlocks can occur).
In cases when SH lock is really required (e.g. when tables
are open by I_S implementation) we rely on that newly
introduced MYSQL_OPEN_FORCE_SHARED_HIGH_PRIO_MDL flag is
used.
sql/sql_delete.cc:
mysql_truncate_by_delete():
Adjust type of metadata lock to be requested after changing
type of thr_lock.c lock for table list element from one
which was set in parser to TL_WRITE.
This removes discrepancy between types of these locks which
allowed deadlocks to creep in.
sql/sql_handler.cc:
When closing table which was open by HANDLER statement clear
TABLE::open_by_handler flag. This allows to use this flag as
a reliable indication that TABLE instance was open by HANDLER
statement in assert which was added to mysql_lock_tables().
sql/sql_parse.cc:
multi_delete_set_locks_and_link_aux_tables():
Adjust type of metadata lock to be requested after changing
type of thr_lock.c lock for table list element from one
which was set in parser to TL_WRITE.
This removes discrepancy between types of these locks which
allowed deadlocks to creep in.
sql/sql_show.cc:
Use newly introduced MYSQL_OPEN_FORCE_SHARED_HIGH_PRIO_MDL
flag in order to acquire SH metadata locks when opening tables
in I_S implementation.
sql/sql_update.cc:
Added comment explaining why in multi-update after deciding
that we need weaker thr_lock.c lock on a table we don't
downgrade metadata lock on it.
sql/sql_view.cc:
When merging view into main statement adjust type of metadata
lock to be requested after changing type of thr_lock.c lock
