3be6493aab Bug#19955: unsigned bigint used as signed with MOD function
Problem:  When we have a really large number (between 2^63 and 2^64)
as the left side of the mod operator, it gets improperly corerced
into a signed value.

Solution:  Added check to see if the "negative" number is really
positive, and if so, cast it.

154c6e0677 Bug#18761: constant expression as UDF parameters not passed in as constant
The code that set up data to be passed to user-defined functions was very
old and analyzed the "Type" of the data that was passed into the UDF, when
it really should analyze the "return_type", which is hard-coded for simple
Items and works correctly for complex ones like functions.

fc83f787cb Fix for bug bug#23651 "Server crashes when trigger which uses
stored function invoked from different connections".

Invocation of trigger which was using stored function from different
connections caused server crashes (for non-debug server this happened
in highly concurrent environment, but debug server failed on assertion
in relatively simple scenario).

Item_func_sp was not safe to use in triggers (in other words for
re-execution from different threads) as artificial TABLE object
pointed by Item_func_sp::dummy_table referenced incorrect THD
object. To fix the problem we force re-initialization of this
object for each re-execution of statement.

mysql-test/t/trigger.test:
  Added test for bug#23651 "Server crashes when trigger which uses

sql/item_func.cc:
  To make Item_func_sp safe for usage in triggers (in other words safe
  for re-execution in different threads) we need to ensure that artificial
  TABLE object pointed by Item_func_sp::dummy_table references correct
  THD object. To achieve this we simply force its re-initialization for
  each re-execution of statement.

3a86738289 Bug#10963: LEFT/RIGHT/SUBSTR/.. string functions returns wrong result \
on large length
  
Problem:  Most (all) of the numeric inputs were being coerced into
int (32 bit) sized variables.  Works OK for sane inputs; any input
larger than 2^32 (or 2^31 for signed vars) exihibited predictable
wrapping behavior (up to about 10^18) and then started having really
strange behaviour past that point (since the conversion to 64 bit int
from the DECIMAL type can do weird things on out of range numbers).

Solution: 1)  Add many tests.  2)  Convert input from (u)long type to
(u)longlong.  3)  Do (sometimes multiple) sanity checks on input,
keeping in mind that sometimes a negative longlong is not a negative
longlong (if the unsigned_flag is set).  4) Emulate existing behavior
w/rt negative and "small" out-of-bounds values.

f51d0812a7 Bug #21809: Error 1356 while selecting from view with grouping though underlying
select OK.
The SQL parser was using Item::name to transfer user defined function attributes
to the user defined function (udf). It was not distinguishing between user defined 
function call arguments and stored procedure call arguments. Setting Item::name 
was causing Item_ref::print() method to print the argument as quoted identifiers 
and caused views that reference aggregate functions as udf call arguments (and 
rely on Item::print() for the text of the view to store) to throw an undefined 
identifier error.
Overloaded Item_ref::print to print aggregate functions as such when printing
the references to aggregate functions taken out of context by split_sum_func2()
Fixed the parser to properly detect using AS clause in stored procedure arguments
as an error.
Fixed printing the arguments of udf call to print properly the udf attribute.

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.

  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

37b5cbdc30 Fix for the patch for bug#21726: Incorrect result with multiple
invocations of LAST_INSERT_ID.

Reding of LAST_INSERT_ID inside stored function wasn't noted by caller,
and no LAST_INSERT_ID_EVENT was issued for binary log.

The solution is to add THD::last_insert_id_used_bin_log, which is much
like THD::last_insert_id_used, but is reset only for upper-level
statements.  This new variable is used to issue LAST_INSERT_ID_EVENT.


mysql-test/r/rpl_insert_id.result:
  For bug#21726, add result for statement-based replication of function
  calls.
mysql-test/t/rpl_insert_id.test:
  For bug#21726, add test case for statement-based replication of function
  calls.
sql/item_func.cc:
  Set THD::last_insert_id_used_bin_log for issuing of LAST_INSERT_ID_EVENT.
sql/log.cc:
  Issue LAST_INSERT_ID_EVENT if THD::last_insert_id_used_bin_log is set.
sql/set_var.cc:
  Set THD::last_insert_id_used_bin_log for issuing of LAST_INSERT_ID_EVENT.

  Fix typo, add whitespace.
sql/sql_class.h:
  Add THD::last_insert_id_used_bin_log.
sql/sql_parse.cc:
  Reset THD::last_insert_id_used_bin_log for upper-level statements.
sql/sql_select.cc:
  Set THD::last_insert_id_used_bin_log for issuing of LAST_INSERT_ID_EVENT.

be929087ec BUG#21726: Incorrect result with multiple invocations of LAST_INSERT_ID
Non-upper-level INSERTs (the ones in the body of stored procedure,
stored function, or trigger) into a table that have AUTO_INCREMENT
column didn't affected the result of LAST_INSERT_ID() on this level.

The problem was introduced with the fix of bug 6880, which in turn was
introduced with the fix of bug 3117, where current insert_id value was
remembered on the first call to LAST_INSERT_ID() (bug 3117) and was
returned from that function until it was reset before the next
_upper-level_ statement (bug 6880).

The fix for bug#21726 brings back the behaviour of version 4.0, and
implements the following: remember insert_id value at the beginning
of the statement or expression (which at that point equals to
the first insert_id value generated by the previous statement), and
return that remembered value from LAST_INSERT_ID() or @@LAST_INSERT_ID.

Thus, the value returned by LAST_INSERT_ID() is not affected by values
generated by current statement, nor by LAST_INSERT_ID(expr) calls in
this statement.

Version 5.1 does not have this bug (it was fixed by WL 3146).


mysql-test/r/rpl_insert_id.result:
  Add results for bug#21726: Incorrect result with multiple invocations
  of LAST_INSERT_ID, and bug#20339: stored procedure using LAST_INSERT_ID()

  Add implementation of Item_func_last_insert_id::fix_fields(), where we
  remember in THD::current_insert_id the first value generated during
  execution of the previous statement, which is returned then from
  Item_func_last_insert_id::val_int().
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() remember in
  THD::current_insert_id the first value generated during execution of the
  previous statement, and return this value for @@LAST_INSERT_ID.
sql/sql_class.cc:
  Reset THD::last_insert_id_used after each statement execution.
sql/sql_class.h:
  Rather then remember current insert_id value on first invocation of
  THD::insert_id(), remember it in Item_func_last_insert_id::fix_fields(),
  sys_var_last_insert_id::value_ptr(), or mysql_execute_command().
  Remove THD::insert_id(), as it lost its value now.
sql/sql_insert.cc:
  THD::insert_id() is removed, use THD::last_insert_id directly.
sql/sql_load.cc:
  THD::insert_id() is removed, using THD::last_insert_id directly is OK.
sql/sql_parse.cc:
  Remember in THD::current_insert_id first generated insert id value of
  the previous statement in mysql_execute_command().
  No need to reset THD::last_insert_id_used in
  mysql_reset_thd_for_next_command(), it will be reset after each
  statement.
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

c623e54fb8 Fixed bug#16861: User defined variable can have a wrong value if a tmp table was
used.

Sorting by RAND() uses a temporary table in order to get a correct results.
User defined variable was set during filling the temporary table and later
on it is substituted for its value from the temporary table. Due to this
it contains the last value stored in the temporary table.

Now if the result_field is set for the Item_func_set_user_var object it 
updates variable from the result_field value when being sent to a client.

The Item_func_set_user_var::check() now accepts a use_result_field
parameter. Depending on its value the result_field or the args[0] is used
to get current value.

9a63adc8fd Fixed bug#19862: Sort with filesort by function evaluates function twice
When there is no index defined filesort is used to sort the result of a
query. If there is a function in the select list and the result set should be
ordered by it's value then this function will be evaluated twice. First time to
get the value of the sort key and second time to send its value to a user.
This happens because filesort when sorts a table remembers only values of its
fields but not values of functions.
All functions are affected. But taking into account that SP and UDF functions
can be both expensive and non-deterministic a temporary table should be used 
to store their results and then sort it to avoid twice SP evaluation and to 
get a correct result.

If an expression referenced in an ORDER clause contains a SP or UDF 
function, force the use of a temporary table.

A new Item_processor function called func_type_checker_processor is added
to check whether the expression contains a function of a particular type.

06bf59ad33 Bug#18630: Arguments of suid routine calculated in wrong security
context.

Routine arguments were evaluated in the security context of the routine
itself, not in the caller's context.

The bug is fixed the following way:

  - Item_func_sp::find_and_check_access() has been split into two
    functions: Item_func_sp::find_and_check_access() itself only
    finds the function and check that the caller have EXECUTE privilege
    on it.  New function set_routine_security_ctx() changes security
    context for SUID routines and checks that definer have EXECUTE
    privilege too.

  - new function sp_head::execute_trigger() is called from
    Table_triggers_list::process_triggers() instead of
    sp_head::execute_function(), and is effectively just as the
    sp_head::execute_function() is, with all non-trigger related code
    removed, and added trigger-specific security context switch.

  - call to Item_func_sp::find_and_check_access() stays outside
    of sp_head::execute_function(), and there is a code in
    sql_parse.cc before the call to sp_head::execute_procedure() that
    checks that the caller have EXECUTE privilege, but both
    sp_head::execute_function() and sp_head::execute_procedure() call
    set_routine_security_ctx() after evaluating their parameters,
    and restore the context after the body is executed.


mysql-test/r/sp-security.result:
  Add test case for bug#18630: Arguments of suid routine calculated
  in wrong security context.
mysql-test/t/sp-security.test:
  Add result for bug#18630: Arguments of suid routine calculated
  in wrong security context.
sql/item_func.cc:
  Do not change security context before executing the function, as it
  will be changed after argument evaluation.
  Do not change security context in Item_func_sp::find_and_check_access().
sql/item_func.h:
  Change prototype for Item_func_sp::find_and_check_access().
sql/sp_head.cc:
  Add set_routine_security_ctx() function.
  Add sp_head::execute_trigger() method.
  Change security context in sp_head::execute_trigger(), and in
  sp_head::execute_function() and sp_head::execute_procedure()
  after argument evaluation.
  Move pop_all_cursors() call to sp_head::execute().
sql/sp_head.h:
  Add declaration for sp_head::execute_trigger() and
  set_routine_security_ctx().
sql/sql_parse.cc:
  Do not change security context before executing the procedure, as it
  will be changed after argument evaluation.
sql/sql_trigger.cc:
  Call new sp_head::execute_trigger() instead of
  sp_head::execute_function(), which is responsible to switch
  security context.
