a temporary table.
The result string of the Item_func_group_concat wasn't initialized in the
copying constructor of the Item_func_group_concat class. This led to a
wrong charset of GROUP_CONCAT result when the select employs a temporary
table.
The copying constructor of the Item_func_group_concat class now correctly
initializes the charset of the result string.

No test case, since the bug requires a stress case with 30 INSERT DELAYED
threads and 1 killer thread to repeat. The patch is verified
manually.
Review fixes.
The server that is running DELAYED inserts would deadlock itself
or crash under high load if some of the delayed threads were KILLed
in the meanwhile.
The fix is to change internal lock acquisition order of delayed inserts
subsystem and to ensure that
Delayed_insert::table_list::db does not point to volatile memory in some
cases.
For details, please see a comment for sql_insert.cc.
sql/sql_insert.cc:
A fix for Bug#29431 killing an insert delayed thread causes crash
1) The deadlock was caused by different lock acquisition order
between delayed_get_table and handle_delayed_insert.
delayed_get_table would:
- acquire LOCK_delayed_create
- create a new Delayed_insert instance
- acquire instance mutex (di->mutex)
- "lock the instance in memory" by
increasing di->locked_in_memory variable
- start the delayed thread
- release di->mutex
- let the delayed thread open the delayed table
- discover that the delayed thread was killed
- try to unlock() the delayed insert instance in memory
- in Delayed_insert::unlock() do
* lock LOCK_delayed_insert
* decrease locks_in_memory and discover it's 0
* attempt to lock di->mutex to broadcast di->cond condition <-- deadlock
here
Meanwhile, the delayed thread would
* lock di->mutex
* open the table
* get killed
* not notice that and attempt to lock LOCK_delayed_insert
to register itself in the delayed insert list <-- deadlock here.
Simply put, delayed_get_table used to lock LOCK_delayed_insert and then
di->mutex, and handle_delayed_insert would lock di->mutex and then
LOCK_delayed_insert.
Fixed by moving registration in the list of delayed insert threads from
handle_delayed_insert to delayed_get_table - so that now
handle_delayed_insert doesn't need to acquire LOCK_delayed_insert mutex.
2) di->table_list.db was copied by-pointer from table_list.db of the first
producer -- the one who initiated creation of the delayed insert thread.
This producer might be long gone when the member is needed
(handle_delayed_insert:open_ltable),
e.g. by having been killed with KILL CONNECTION statement.
Fixed by using a pointer to the consumer's deep copy of THD::db.
3) In find_handler, we shouldn't assume that Delayed_insert object
already (or still) has a table opened all the time it is
present in the delayed insert list. E.g. it's not the case
when Delayed_insert decided to terminate, closed the table, but haven't
yet unregistered from the list (see the end of handle_delayed_insert).

Optimization of queries with DETERMINISTIC functions in the
WHERE clause was not effective: sequential scan was always
used.
Now a SF with the DETERMINISTIC flags is treated as constant
when it's arguments are constants (or a SF doesn't has arguments).
sql/item_func.h:
Fixed bug #29338.
The Item_func_sp::used_tables has been removed
(virtual Item_func::used_tables function is enough).
The virtual Item_func_sp::update_used_tables function
has been added.
sql/item_func.cc:
Fixed bug #29338.
The Item_func_sp::update_used_tables and the

asserts.
The patch for Bug#21074 replaces acquisition of the global LOCK_open lock
with exclusive locks on table names in such operations ad DROP TABLE
and RENAME TABLE.
Unfortunately, NDB internally assumes that LOCK_open is acquired and
tries to release it.
This dependency should be fixed by a separate (and significant in size)
patch. For now we just satisfy it - after all, the original
goal of the patch for Bug#21074 was to move query_cache_invalidate
outside of the scope of LOCK_open, and we still can do that.
This fixes some failing NDB tests in the runtime tree.
