c4d53e31b0 Bug#15130: CREATE .. SELECT was denied to use advantages of the SQL_BIG_RESULT.
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.

d50caace5f Fixed bug #29611.
If a primary key is defined over column c of enum type then 
the EXPLAIN command for a look-up query of the form
  SELECT * FROM t WHERE c=0
said that the query was with an impossible where condition though the
query correctly returned non-empty result set when the table indeed 
contained rows with error empty strings for column c. 

This kind of misbehavior was due to a bug in the function 
Field_enum::store(longlong,bool) that erroneously returned 1 if
the the value to be stored was equal to 0. 
Note that the method 
Field_enum::store(const char *from,uint length,CHARSET_INFO *cs)
correctly returned 0 if a value of the error empty string 
was stored.

72c6c789cf Fixed bug #29911.
This bug manifested itself for join queries with GROUP BY and HAVING clauses
whose SELECT lists contained DISTINCT. It occurred when the optimizer could
deduce that the result set would have not more than one row.
The bug could lead to wrong result sets for queries of this type because
HAVING conditions were erroneously ignored in some cases in the function
remove_duplicates.

cff531ffc1 Fixed bug #29788.
After dumping triggers mysqldump copied 
the value of the OLD_SQL_MODE variable to the SQL_MODE
variable. If the --compact option of the mysqldump was
not set the OLD_SQL_MODE variable had the value
of the uninitialized SQL_MODE variable. So
usually the NO_AUTO_VALUE_ON_ZERO option of the
SQL_MODE variable was discarded.

This fix is for non-"--compact" mode of the mysqldump,
because mysqldump --compact never set SQL_MODE to the
value of NO_AUTO_VALUE_ON_ZERO.

The dump_triggers_for_table function has been modified
to restore previous value of the SQL_MODE variable after
dumping triggers using the SAVE_SQL_MODE temporary
variable.

95a8c6c327 Bug #28591: MySQL need not sort the records in case of
ORDER BY primary_key on InnoDB table

Queries that use an InnoDB secondary index to retrieve
data don't need to sort in case of ORDER BY primary key
if the secondary index is compared to constant(s).
They can also skip sorting if ORDER BY contains both the
the secondary key parts and the primary key parts (in
that order).
This is because InnoDB returns the rows in order of the
primary key for rows with the same values of the secondary
key columns.
Fixed by preventing temp table sort for the qualifying 
queries.

eea5c2a3c5 Bug #29644: alter table hangs if records locked in share mode
by long running transaction

On Windows opened files can't be deleted. There was a special
upgraded lock mode (TL_WRITE instead of TL_WRITE_ALLOW_READ) 
in ALTER TABLE to make sure nobody has the table opened
when deleting the old table in ALTER TABLE. This special mode
was causing ALTER TABLE to hang waiting on a lock inside InnoDB.
This special lock is no longer necessary as the server is 
closing the tables it needs to delete in ALTER TABLE.
Fixed by removing the special lock.
Note that this also reverses the fix for bug 17264 that deals with
another consequence of this special lock mode being used.

2bfe84d434 Fixed bug #28524.
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.

b7527f6b72 Bug #29579 Clients using SSL can hang the server
Added an option to yassl to allow "quiet shutdown" like openssl does. This option causes the SSL libs to NOT perform the close_notify handshake during shutdown. This fixes a hang we experience because we hold a lock during socket shutdown.


mysql-test/t/ssl_big.test:
  BitKeeper file /Users/dkatz/50/mysql-test/t/ssl_big.test
mysql-test/r/ssl-big.result:
  BitKeeper file /Users/dkatz/50/mysql-test/r/ssl-big.result
client/mysqltest.c:
  Added new command to mysqltest to send a quit command to the server, but to not close the actual socket on our end.
  
  Also changed code to reuse connection slots, so that the tests can open and close sockets in a loop.
extra/yassl/include/openssl/ssl.h:
  Added C accessors to the quietShutdown option.
extra/yassl/include/yassl_int.hpp:
  Added quietShutdown_ member and accessor methods to the SSL class.
extra/yassl/src/ssl.cpp:
  Added accessors to get/set the quietShutdown option and to not perform the shutdown handshake if quietShutdown is set.
extra/yassl/src/yassl_int.cpp:
  Added quietShutdown_ member and accessor methods to the SSL class.
vio/viossl.c:
  Added line to set the quiet_shutdown option before shutting down the socket.
mysql-test/t/ssl-big.test:
  Added a test that causes an unpatched server to hang during SSL socket shutdown.

e08e63b192 Bug#29739: Incorrect time comparison in BETWEEN.
Time values were compared by the BETWEEN function as strings. This led to a
wrong result in cases when some of arguments are less than 100 hours and other
are greater.

Now if all 3 arguments of the BETWEEN function are of the TIME type then
they are compared as integers.


mysql-test/t/type_time.test:
  Added a tes tcase for the bug#29739: Incorrect time comparison in BETWEEN.
mysql-test/r/type_time.result:
  Added a tes tcase for the bug#29739: Incorrect time comparison in BETWEEN.
sql/item_cmpfunc.cc:
  Bug#29739: Incorrect time comparison in BETWEEN.

9dc3088f9e A fix and a test case for Bug#26141 mixing table types in trigger
causes full table lock on innodb table.
Also fixes Bug#28502 Triggers that update another innodb table 
will block on X lock unnecessarily (duplciate).
Code review fixes.

Both bugs' synopses are misleading: InnoDB table is
not X locked. The statements, however, cannot proceed concurrently, 
but this happens due to lock conflicts for tables used in triggers,
not for the InnoDB table. 

If a user had an InnoDB table, and two triggers, AFTER UPDATE and 
AFTER INSERT, competing for different resources (e.g. two distinct
MyISAM tables), then these two triggers would not be able to execute
concurrently. Moreover, INSERTS/UPDATES of the InnoDB table would
not be able to run concurrently. 
The problem had other side-effects (see respective bug reports).

This behavior was a consequence of a shortcoming of the pre-locking
algorithm, which would not distinguish between different DML operations
(e.g. INSERT and DELETE) and pre-lock all the tables
that are used by any trigger defined on the subject table.

The idea of the fix is to extend the pre-locking algorithm to keep track,
for each table, what DML operation it is used for and not
load triggers that are known to never be fired.


mysql-test/r/trigger-trans.result:
  Update results (Bug#26141)
mysql-test/r/trigger.result:
  Update results (Bug#28502)
mysql-test/t/trigger-trans.test:
  Add a test case for Bug#26141 mixing table types in trigger causes 
  full table lock on innodb table.
mysql-test/t/trigger.test:
  Add a test case for Bug#28502 Triggers that update another innodb 
  table will block echo on X lock unnecessarily. Add more test 
  coverage for triggers.
sql/item.h:
  enum trg_event_type is needed in table.h
sql/sp.cc:
  Take into account table_list->trg_event_map when determining
  what tables to pre-lock. 
  
  After this change, if we attempt to fire a 
  trigger for which we had not pre-locked any tables, error
  'Table was not locked with LOCK TABLES' will be printed.
  This, however, should never happen, provided the pre-locking
  algorithm has no programming bugs.
  
  Previously a trigger key in the sroutines hash was based on the name 
  of the table the trigger belongs to. This was possible because we would
  always add to the pre-locking list all the triggers defined for a table when
  handling this table.
  Now the key is based on the name of the trigger, owing
  to the fact that a trigger name must be unique in the database it
  belongs to.
sql/sp_head.cc:
  Generate sroutines hash key in init_spname(). This is a convenient
  place since there we have all the necessary information and can
  avoid an extra alloc.
  
  Maintain and merge trg_event_map when adding and merging elements
  of the pre-locking list.
sql/sp_head.h:
  Add ,m_sroutines_key member, used when inserting the sphead for a
  trigger into the cache of routines used by a statement.
  Previously the key was based on the table name the trigger belonged
  to, since for a given table we would add to the sroutines list
  all the triggers defined on it.
sql/sql_lex.cc:
  Introduce a new lex step: set_trg_event_type_for_tables().
  It is called when we have finished parsing but before opening
  and locking tables. Now this step is used to evaluate for each
  TABLE_LIST instance which INSERT/UPDATE/DELETE operation, if any,
  it is used in.
  In future this method could be extended to aggregate other information
  that is hard to aggregate during parsing.
sql/sql_lex.h:
  Add declaration for set_trg_event_type_for_tables().
sql/sql_parse.cc:
  Call set_trg_event_type_for_tables() after MYSQLparse(). Remove tabs.
sql/sql_prepare.cc:
  Call set_trg_event_type_for_tables() after  MYSQLparse().
sql/sql_trigger.cc:
  Call set_trg_event_type_for_tables() after MYSQLparse().
sql/sql_trigger.h:
  Remove an obsolete member.
sql/sql_view.cc:
  Call set_trg_event_type_for_tables() after MYSQLparse().
sql/sql_yacc.yy:
  Move assignment of sp_head::m_type before calling sp_head::init_spname(), 
  one is now used inside another.
sql/table.cc:
  Implement TABLE_LIST::set_trg_event_map() - a method that calculates
  wh triggers may be fired on this table when executing a statement.
sql/table.h:
  Add missing declarations.
  Move declaration of trg_event_type from item.h (it will be needed for 
  trg_event_map bitmap when we start using Bitmap template instead
  of uint8).
