3c10858474 Fix for BUG#16211: Stored function return type for strings is ignored.
Fix for BUG#16676: Database CHARSET not used for stored procedures

The problem in BUG#16211 is that CHARSET-clause of the return type for
stored functions is just ignored.

The problem in BUG#16676 is that if character set is not explicitly
specified for sp-variable, the server character set is used instead
of the database one.

The fix has two parts:

  - always store CHARSET-clause of the return type along with the
    type definition in mysql.proc.returns column. "Always" means that
    CHARSET-clause is appended even if it has not been explicitly
    specified in CREATE FUNCTION statement (this affects BUG#16211 only).

    Storing CHARSET-clause if it is not specified is essential to avoid
    changing character set if the database character set is altered in
    the future.

    NOTE: this change is not backward compatible with the previous releases.

  - use database default character set if CHARSET-clause is not explicitly
    specified (this affects both BUG#16211 and BUG#16676).

    NOTE: this also breaks backward compatibility.

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.

0fa250a936 A fix and a test case for Bug#21002 "Derived table not selecting from a
"real" table fails in JOINs".

This is a regression caused by the fix for Bug 18444. 
This fix removed the assignment of empty_c_string to table->db performed 
in add_table_to_list, as neither me nor anyone else knew what it was 
there for. Now we know it and it's covered with tests: the only case 
when a table database name can be empty is when the table is a derived 
table. The fix puts the assignment back but makes it a bit more explicit.

Additionally, finally drop sp.result.orig which was checked in by mistake.

ca00a985a1 Bug#21013: Performance Degrades when importing data that uses Trigger
and Stored Procedure

The essence of the bug was that for every re-execution of stored
routine or prepared statement new items for character set conversions
were created, thus increasing the number of items and the time of their
processing, and creating memory leak.

No test case is provided since current test suite can't cover such type
of bugs.

d6bcbfbe92 A fix and a test case for
Bug#19022 "Memory bug when switching db during trigger execution"
 Bug#17199 "Problem when view calls function from another database."
 Bug#18444 "Fully qualified stored function names don't work correctly in
            SELECT statements"

 Documentation note: this patch introduces a change in behaviour of prepared
 statements.

 This patch adds a few new invariants with regard to how THD::db should
 be used. These invariants should be preserved in future:

  - one should never refer to THD::db by pointer and always make a deep copy
    (strmake, strdup)
  - one should never compare two databases by pointer, but use strncmp or
    my_strncasecmp
  - TABLE_LIST object table->db should be always initialized in the parser or
    by creator of the object.

    For prepared statements it means that if the current database is changed
    after a statement is prepared, the database that was current at prepare
    remains active. This also means that you can not prepare a statement that
    implicitly refers to the current database if the latter is not set.
    This is not documented, and therefore needs documentation. This is NOT a
    change in behavior for almost all SQL statements except:
     - ALTER TABLE t1 RENAME t2 
     - OPTIMIZE TABLE t1
     - ANALYZE TABLE t1
     - TRUNCATE TABLE t1 --
     until this patch t1 or t2 could be evaluated at the first execution of
     prepared statement. 

     CURRENT_DATABASE() still works OK and is evaluated at every execution
     of prepared statement.

     Note, that in stored routines this is not an issue as the default
     database is the database of the stored procedure and "use" statement
     is prohibited in stored routines.

  This patch makes obsolete the use of check_db_used (it was never used in the
  old code too) and all other places that check for table->db and assign it
  from THD::db if it's NULL, except the parser.

 How this patch was created: THD::{db,db_length} were replaced with a
 LEX_STRING, THD::db. All the places that refer to THD::{db,db_length} were
 manually checked and:
  - if the place uses thd->db by pointer, it was fixed to make a deep copy
  - if a place compared two db pointers, it was fixed to compare them by value
    (via strcmp/my_strcasecmp, whatever was approproate)
 Then this intermediate patch was used to write a smaller patch that does the
 same thing but without a rename.

 TODO in 5.1:
   - remove check_db_used
   - deploy THD::set_db in mysql_change_db

67fd3c4a53 A fix and a test case for Bug#15217 "Using a SP cursor on a table created
with PREPARE fails with weird error".
More generally, re-executing a stored procedure with a complex SP cursor query
could lead to a crash.

The cause of the problem was that SP cursor queries were not optimized 
properly at first execution: their parse tree belongs to sp_instr_cpush,
not sp_instr_copen, and thus the tree was tagged "EXECUTED" when the
cursor was declared, not when it was opened. This led to loss of optimization
transformations performed at first execution, as sp_instr_copen saw that the
query is already "EXECUTED" and therefore either not ran first-execution 
related blocks or wrongly rolled back the transformations caused by 
first-execution code.
The fix is to update the state of the parsed tree only when the tree is
executed, as opposed to when the instruction containing the tree is executed.
Assignment if i->state is moved to reset_lex_and_exec_core.

4f15a043e2 Fix for bugs#12472/#15137 'CREATE TABLE ... SELECT ... which explicitly
or implicitly uses stored function gives "Table not locked" error'

CREATE TABLE ... SELECT ... statement which was explicitly or implicitly
(through view) using stored function gave "Table not locked" error.

The actual bug resides in the current locking scheme of CREATE TABLE SELECT
code, which first opens and locks tables of the SELECT statement itself,
and then, having SELECT tables locked, creates the .FRM, opens the .FRM and
acquires lock on it. This scheme opens a possibility for a deadlock, which
was present and ignored since version 3.23 or earlier. This scheme also
conflicts with the invariant of the prelocking algorithm -- no table can
be open and locked while there are tables locked in prelocked mode.

The patch makes an exception for this invariant when doing CREATE TABLE ...
SELECT, thus extending the possibility of a deadlock to the prelocked mode.
We can't supply a better fix in 5.0.

  Also now when we are executing CREATE TABLE ... SELECT ... statement which
  SELECT part requires execution in prelocked mode we ignore set of locked
  tables in order to get access to the table we just have created.
  We probably don't want to do this if we are under real LOCK TABLES since
  it will widen window for deadlock too much.
sql/sql_table.cc:
  Moved create_table_from_items() routine into sql_insert.cc, since it was not

This fix makes TRUNCATE in stored procedures to be handled exactly
in the same way as straight TRUNCATE. We achieve this by rolling
back the fix for bug 8850, which is no longer needed since stored
procedures don't require prelocked mode anymore (and TRUNCATE is
not allowed in stored functions or triggers).

fb36d923ce Fixed BUG#16474: SP crashed MySQL
fix_fields() was not called for "order by" variables if the type was a
  "constant integer", and thus interpreted as a column index.
  However, a local variable is an expression and should not be interpreted
  as a column index. Instead it behaves just like when using a user variable
  for instance (i.e. it will not affect the ordering).

50c8c206fc Fixed bug#13575: SP funcs in select with distinct/group and order by can
produce wrong data

By default Item_sp_func::val_str() returns string from it's result_field 
internal buffer. When grouping is present Item_copy_string is used to 
store SP function result, but it doesn't additionally buffer the result.
When the next record is read, internal buffer is overwritten, due to
this Item_copy_string::val_str() will have wrong data. Thus producing
weird query result.

The Item_func_sp::val_str() now makes a copy of returned value to prevent
occasional corruption.

7f02b0a01b Fixed BUG#16887: Cursor causes server segfault
The problem was a code generation bug: cpop instructions were not generated
  when using ITERATE back to an outer block from a context with a declared
  cursor; this would make it push a new cursor without popping in-between,
  eventually overrunning the cursor stack with a crash as the result.
  Fixed the calculation of how many cursors to pop (in sp_pcontext.cc:
  diff_cursors()), and also corrected diff_cursors() and diff_handlers()
  to when doing a "leave"; don't include the last context we're leaving
  (we are then jumping to the appropriate pop instructions).

af187fa29d Fixed on BUG#16568: Continue handler with simple CASE not working correctly
After trying multiple inheritance (to messy and hard make it work) and
  sublassing jump_if_not (worked, but ugly), decided to on this solution
  instead:
  Inserting an abstract sp_instr_opt_meta class as parent for all instructions
  with destinations makes it possible to handle a continuation pointer for
  sp_instr_set_case_expr too.
  Note: No special test case; the fix is captured by the changed behaviour of
  bug14643_2, and bug14498_4 (formerly disabled), in sp.test.

9c4985de77 A fix and a test case for Bug#15441 "Running SP causes Server
to Crash": the bug was that due to non-standard name
resolution precedence in stored procedures (See Bug#5967)
a stored procedure variable took precedence over a table column
when the arguments for VALUES() function were resolved.
The implementation of VALUES() function was not designed to work
with Item_splocal and crashed.
VALUES() function is non-standard. It can refer to, and
is meaningful for, table columns only. The patch disables SP 
variables as possible arguments of VALUES() function.

6b2f13098a Patch for WL#2894: Make stored routine variables work
according to the standard.

The idea is to use Field-classes to implement stored routines
variables. Also, we should provide facade to Item-hierarchy
by Item_field class (it is necessary, since SRVs take part
in expressions).

The patch fixes the following bugs:
  - BUG#8702: Stored Procedures: No Error/Warning shown for inappropriate data 
    type matching; 
 
  - BUG#8768: Functions: For any unsigned data type, -ve values can be passed 
    and returned; 
 
  - BUG#8769: Functions: For Int datatypes, out of range values can be passed 
    and returned; 
 
  - BUG#9078: STORED PROCDURE: Decimal digits are not displayed when we use 
    DECIMAL datatype; 
 
  - BUG#9572: Stored procedures: variable type declarations ignored; 
 
  - BUG#12903: upper function does not work inside a function; 
 
  - BUG#13705: parameters to stored procedures are not verified; 
 
  - BUG#13808: ENUM type stored procedure parameter accepts non-enumerated
    data; 
 
  - BUG#13909: Varchar Stored Procedure Parameter always BINARY string (ignores 
    CHARACTER SET); 
 
  - BUG#14161: Stored procedure cannot retrieve bigint unsigned;

  - BUG#14188: BINARY variables have no 0x00 padding;

  - BUG#15148: Stored procedure variables accept non-scalar values;
