f603c1cce8 BUG#21726: Incorrect result with multiple invocations of LAST_INSERT_ID.
Note: bug#21726 does not directly apply to 4.1, as it doesn't have stored
procedures.  However, 4.1 had some bugs that were fixed in 5.0 by the
patch for bug#21726, and this patch is a backport of those fixes.
Namely, in 4.1 it fixes:

  - LAST_INSERT_ID(expr) didn't return value of expr (4.1 specific).

  - LAST_INSERT_ID() could return the value generated by current
    statement if the call happens after the generation, like in

      CREATE TABLE t1 (i INT AUTO_INCREMENT PRIMARY KEY, j INT);
      INSERT INTO t1 VALUES (NULL, 0), (NULL, LAST_INSERT_ID());

  - Redundant binary log LAST_INSERT_ID_EVENTs could be generated.


mysql-test/r/rpl_insert_id.result:
  Add result for bug#21726: Incorrect result with multiple invocations
  of LAST_INSERT_ID.
mysql-test/t/rpl_insert_id.test:
  Add test case for bug#21726: Incorrect result with multiple invocations
  of LAST_INSERT_ID.
sql/item_func.cc:
  Add implementation of Item_func_last_insert_id::fix_fields(), where we
  set THD::last_insert_id_used when statement calls LAST_INSERT_ID().
  In Item_func_last_insert_id::val_int(), return THD::current_insert_id
  if called like LAST_INSERT_ID(), otherwise return value of argument if
  called like LAST_INSERT_ID(expr).
sql/item_func.h:
  Add declaration of Item_func_last_insert_id::fix_fields().
sql/log_event.cc:
  Do not set THD::last_insert_id_used on LAST_INSERT_ID_EVENT.  Though we
  know the statement will call LAST_INSERT_ID(), it wasn't called yet.
sql/set_var.cc:
  In sys_var_last_insert_id::value_ptr(), set THD::last_insert_id_used,
  and return THD::current_insert_id for @@LAST_INSERT_ID.
sql/sql_class.h:
  Update comments.
  Remove THD::insert_id(), as it has lost its purpose now.
sql/sql_insert.cc:
  Now it is OK to read THD::last_insert_id directly.
sql/sql_load.cc:
  Now it is OK to read THD::last_insert_id directly.
sql/sql_parse.cc:
  In mysql_execute_command(), remember THD::last_insert_id (first
  generated value of the previous statement) in THD::current_insert_id,
  which then will be returned for LAST_INSERT_ID() and @@LAST_INSERT_ID.
sql/sql_select.cc:
  If "IS NULL" is replaced with "= <LAST_INSERT_ID>", use right value,
  which is THD::current_insert_id, and also set THD::last_insert_id_used
  to issue binary log LAST_INSERT_ID_EVENT.
sql/sql_update.cc:
  Now it is OK to read THD::last_insert_id directly.
tests/mysql_client_test.c:
  Add test case for bug#21726: Incorrect result with multiple invocations
  of LAST_INSERT_ID.

a1017b09b4 Bug#8663 cant use bgint unsigned as input to cast
Problem: cast to unsigned limited result to 
max signed bigint 9223372036854775808,
instead of max unsigned bigint 18446744073709551615.

Fix: don't use args[0]->val_int() when casting from
a floating point number, use val() instead, with range checkings,
special to unsigned data type.

item_func.cc:
  Special handling of cast from REAL_RESULT
  to unsigned int: we cannot execute args[0]->val_int()
  because it cuts max allowed value to LONGLONG_INT,
  instead of ULONGLONG_INT required.

4ab4631b06 Bug#19136: Crashing log-bin and uninitialized user variables in a derived table
The reason of the bug is in that `get_var_with_binlog' performs missed
assingment of
the variables as side-effect. Doing that it eventually calls
`free_underlaid_joins' to pass as an argument `thd->lex->select_lex' of the lex
which belongs to the user query, not 
to one which is emulated i.e SET @var1:=NULL.


`get_var_with_binlog' is refined to supply a temporary lex to sql_set_variables's stack.

a2066982f1 Fixed bug#14169: type of group_concat() result changed to blob if tmp_table was
used

In a simple queries a result of the GROUP_CONCAT() function was always of 
varchar type.
But if length of GROUP_CONCAT() result is greater than 512 chars and temporary
table is used during select then the result is converted to blob, due to
policy to not to store fields longer than 512 chars in tmp table as varchar
fields.

In order to provide consistent behaviour, result of GROUP_CONCAT() now
will always be converted to blob if it is longer than 512 chars.
Item_func_group_concat::field_type() is modified accordingly.

  The unnamed constant 255 in the create_tmp_field() and create_tmp_field_from_item() functions now defined as the CONVERT_IF_BIGGER_TO_BLOB constant.
  The create_tmp_field() function now converts the Item_sum string result to a blob field based on its char length.
sql/item_sum.h:
  Fixed bug#14169: type of group_concat() result changed to blob if tmp_table was used
  To the Item_func_group_concat calls added the member function field_type() which returns the BLOB or VAR_STRING type based on the items length.
sql/item_func.cc:
  Fixed bug#14169: type of group_concat() result changed to blob if tmp_table was used
  In the Item_func::tmp_table_field() function the unnamed constant 255 is changed to the CONVERT_IF_BIGGER_TO_BLOB constant.
  The Item_func::tmp_table_field() function now measures the result length in chars rather than bytes when converting string result to a blob.

9fcda7fcc5 A fix and test case for Bug#9096 "select doesn't return all matched
records if prepared statements is used".
This fix changes equality evaluation method of basic constants from
by-name to by-value, thus effectively enabling use of parameter markers
in some optimizations (constants propagation, evaluation of possible
keys for query).


mysql-test/r/ps.result:
  Test results for the test case for Bug#9096
mysql-test/t/ps.test:
  A short test case for Bug#9096 "select doesn't return all matched records if
   prepared statements is used". The is enough to reproduce the
  glitch in update_ref_and_keys causing the bug to occur.
sql/item.cc:
  Implement by-value equality evaluation of basic constants.
  This is needed to work with Item_param values. Until now
  Item_param was compared with other items by its name, which is always "?".
  The bug at hand showed up when an integer
  constant was created from one parameter marker (with value 200887 and
   name "?") and then compared by-name with another parameter marker
  (with value 860 and name "?"). True returned by this comparison resulted
  in a wrong table access method used to evaluate the query.
  Implement Item_param methods needed to emulate "basic constant" mode at 
  full.
sql/item.h:
  Change declaration of basic_const_item(): now it also widens its 
  argument from const Item * to Item * if the argument is a basic constant.
  Declare eq() for all basic constatns, as long as now they 
  are compared by value, not by name. Each constant needs its own
  comparison method.
  Declarations of Item_param methods needed to fully emulate 
  a basic constant when parameter value is set.
sql/item_func.cc:
  Fix wrong casts.

e6ce543f05 Fix for Bug #9913 "udf_deinit is not called after execution of PS"
(aka "deinit is not called when calling udf from trigger").

We should call udf_deinit() function during cleanup phase after prepared
(or ordinary) statement execution instead of calling it from Item's
desctructor.

No test case is provided since it is hard to test UDF's from our test
suite.


sql/item_func.cc:
  udf_handler:
   Moved all functionality from udf_handler::~udf_handler() to 
   udf_handler::cleanup() method which will be called after
   each PS execution, thus allowing udf_deinit() to be executed
   symetrically with udf_init() (which is executed for each
   execution of PS).
  Added Item_udf_func::cleanup() which performs proper cleanup after
  execution of PS with UDF function.
sql/item_func.h:
  Added Item_udf_func::cleanup() method to perform cleanup properly after
  execution of PS with UDF function.
sql/item_sum.cc:
  Added Item_udf_sum::cleanup() method to perform cleanup properly after
  execution of PS with aggregate UDF function.
sql/item_sum.h:
  Added Item_udf_sum::cleanup() method to perform cleanup properly after
  execution of PS with aggregate UDF function.
sql/sql_udf.h:
  Added udf_handler::cleanup() method declaration which is responsible
  for cleaning up UDF execution context at the end of execution of
  statement (using ~udf_handler() for this purprose did not worked for PS).

  Bug#8291: Illegal collation mix with USER() function.
  After discussion with PeterG and Serge, a new coercibility
  level for "system constants" was introduced, between
  COERRIBLE and IMPLICIT. Thus:
  SELECT col1 = USER() FROM t1; - is done according to col1 collation.
  SELECT 'string' = USER(); - is done according to USER() collation.
  At the same time, "nagg" and "strong" members were removed as unused.
sql/item_create.cc:
  Version is a system constant too.
sql/item_func.cc:
