Bug #27417 thd->no_trans_update.stmt lost value inside of SF-exec-stack
  
Once had been set the flag might later got reset inside of a stored routine 
execution stack.
The reason was in that there was no check if a new statement started at time 
of resetting.
The artifact affects most of binlogable DML queries. Notice, that multi-update 
is wrapped up within
  bug@27716 fix, multi-delete bug@29136.
  
Fixed with saving parent's statement flag of whether the statement modified 
non-transactional table, and unioning (merging) the value with that was gained 
in mysql_execute_command.
  
Resettling thd->no_trans_update members into thd->transaction.`member`;
Asserting code;
Effectively the following properties are held.
  
1. At the end of a substatement thd->transaction.stmt.modified_non_trans_table
   reflects the fact if such a table got modified by the substatement.
   That also respects THD::really_abort_on_warnin() requirements.
2. Eventually thd->transaction.stmt.modified_non_trans_table will be computed as
   the union of the values of all invoked sub-statements.
   That fixes this bug#27417;

Computing of thd->transaction.all.modified_non_trans_table is refined to base to 
the stmt's value for all the case including insert .. select statement which 
before the patch had an extra issue bug@28960.
Minor issues are covered with mysql_load, mysql_delete, and binloggin of insert in
to temp_table select. 
  
The supplied test verifies limitely, mostly asserts. The ultimate testing is defered
for bug@13270, bug@23333.

information schema table.

The get_schema_views_record() function fills records in the view table of
the informations schema with data about given views. Among other info
the is_updatable flag is set. But the check whether the view is updatable or
not wasn't covering all cases thus sometimes providing wrong info.
This might led to a user confusion.

Now the get_schema_views_record function additionally calls to the 
view->can_be_merge() function to find out whether the view can be updated or
not.

  Added a test case for the bug#30020: Insufficient check led to a wrong info

The subst_spvars function is used to create query string with SP variables 
substituted with their values. This string is used later for the binary log
and for the query cache. The problem is that the
query_cache_send_result_to_client function requires some additional space
after the query to store database name and query cache flags. This 
space wasn't reserved by the subst_spvars function which led to a memory
corruption and crash.

Now the subst_spvars function reserves additional space for the query cache.

Item_func_user doesn't calculate anything in it's val_str() method,
just returns saved str_value.
Though Item::save_in_field method can destroy str_value, relying on
val_str() return. As a result we get the garbage stored in field.

We cannot use Item::save_in_field implementation for Item_func_user,
reimplement it in simpler way.

INSERT/DELETE/UPDATE followed by ALTER TABLE within LOCK TABLES
may cause table corruption on Windows.

That happens because ALTER TABLE writes outdated shared state
info into index file.

Fixed by removing obsolete workaround.

Affects MyISAM tables on Windows only.


myisam/mi_extra.c:
  On windows when mi_extra(HA_EXTRA_PREPARE_FOR_DELETE) is called,
  we release external lock and close index file. If we're in LOCK
  TABLES, MyISAM state info doesn't get updated until UNLOCK TABLES.
  
  That means when we release external lock and we're in LOCK TABLES,
  we may write outdated state info.
  
  As SQL layer closes all table instances, we do not need this
  workaround anymore.

 the master but on the slave

MySQL can decide to "downgrade" a INSERT DELAYED statement
to normal insert in certain situations.
One such situation is when the slave is replaying a 
replication feed.
However INSERT DELAYED is logged even if there're no updates
whereas the NORMAL INSERT is not logged in such cases.

Fixed by always logging a "downgraded" INSERT DELAYED: even 
if there were no updates.

  "Federated Denial of Service"
  Federated storage engine used to attempt to open connections within
  the ::create() and ::open() methods which are invoked while LOCK_open
  mutex is being held by mysqld. As a result, no other client sessions
  can open tables while Federated is attempting to open a connection.
  Long DNS lookup times would stall mysqld's operation and a rogue
  connection string which connects to a remote server which simply
  stalls during handshake can stall mysqld for a much longer period of
  time.
  This patch moves the opening of the connection much later, when the
  federated actually issues queries, by which time the LOCK_open mutex is
  no longer being held.

When the SQL_BIG_RESULT flag is specified SELECT should store items from the
select list in the filesort data and use them when sending to a client.
The get_addon_fields function is responsible for creating necessary structures
for that. But this function was allowed to do so only for SELECT and
INSERT .. SELECT queries. This makes the SQL_BIG_RESULT useless for
the CREATE .. SELECT queries.

Now the get_addon_fields allows storing select list items in the filesort
data for the CREATE .. SELECT queries.

  "getGeneratedKeys() does not work with FEDERATED table"
  mysql_insert() expected the storage engine to update the row data
  during the write_row() operation with the value of the new auto-
  increment field. The field must be updated when only one row has
  been inserted as mysql_insert() would ignore the thd->last_insert.
  This patch implements HA_STATUS_AUTO support in ha_federated::info()
  and ensures that ha_federated::write_row() does update the row's
  auto-increment value.
  The test case was written in C as the protocol's 'id' value is
  accessible through libmysqlclient and not via SQL statements.
  mysql-test-run.pl was extended to enable running the test binary.
