Invaldating a subset of a sufficiently large query cache can take a long time.
During this time the server is efficiently frozen and no other operation can
be executed. This patch addresses this problem by setting a time limit on
how long time a dictionary access request can take before giving up on the 
attempt. This patch does not work for query cache invalidations issued by
DROP, ALTER or RENAME TABLE operations.


sql/sql_cache.cc:
  Changed mutex locking to a timed spinn lock. If access to query cache dictionary
  takes "a long time" (currently more than 0.1 seconds) the system fall backs on
  ordinary statement execution.

When a table was explicitly locked with LOCK TABLES no associated
tables from any related trigger on the subject table were locked.
As a result of this the user could experience unexpected locking
behavior and statement failures similar to "failed: 1100: Table'xx'
was not locked with LOCK TABLES".

This patch fixes this problem by making sure triggers are
pre-loaded on any statement if the subject table was explicitly
locked with LOCK TABLES.

  - Refactored set_trg_event_tpye into the two simpler functions set_trg_event_map
    and set_trg_event_map as methods for manipulating the table event map.
    The original function was only called from st_lex::set_trg_event_type_for_tables
    so it was possible to move the event map creation logic to this function as
    a loop optimization.

  BUG#20815 Set stack size. This value is really supposed to be the linker's default. I'm not quite sure why we have to specify it manually too.

The Item_date_typecast::val_int function doesn't reset null_value flag.
This makes all values that follows the first null value to be treated as nulls
and led to a wrong result.

Now the Item_date_typecast::val_int function correctly sets the null_value flag
for both null and non-null values.

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.

for consistency.

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).

For each view the mysqldump utility creates a temporary table
with the same name and the same columns as the view 
in order to satisfy views that depend on this view.
After the creation of all tables, mysqldump drops all
temporary tables and creates actual views.
However, --skip-add-drop-table and --compact flags disable
DROP TABLE statements for those temporary tables. Thus, it was
impossible to create the views because of existence of the
temporary tables with the same names.
