0a7a55d175 Fix for bug #32103: optimizer crash when join on int and mediumint with
variable in where clause.

Problem: the new_item() method of Item_uint used an incorrect
constructor. "new Item_uint(name, max_length)" calls
Item_uint::Item_uint(const char *str_arg, uint length) which assumes the
first argument to be the string representation of the value, not the
item's name. This could result in either a server crash or incorrect
results depending on usage scenarios.

Fixed by using the correct constructor in new_item():
Item_uint::Item_uint(const char *str_arg, longlong i, uint length).

04311fabaa Bug #28550 "Potential bugs related to the return type of the CHAR function".
Since, as of MySQL 5.0.15, CHAR() arguments larger than 255 are converted into multiple result bytes, a single CHAR() argument can now take up to 4 bytes. This patch fixes Item_func_char::fix_length_and_dec() to take this into account.
  
This patch also fixes a regression introduced by the patch for bug21513. As now we do not always have the 'name' member of Item set for Item_hex_string and Item_bin_string, an own print() method has been added to Item_hex_string so that it could correctly be printed by Item_func::print_args().

813e6bcbbd Bug #31155 gis types in union'd select cause crash.
We use get_geometry_type() call to decide the exact type
of a geometry field to be created (POINT, POLYGON etc)
Though this function was only implemented for few items.
In the bug's case we need to call this function for the
Item_sum instance, where it was not implemented, what is
the reason of the crash.
Fixed by implementing virtual Item::get_geometry_type(),
so it can be called for any Item.

582388e6d2 Bug #30832: Assertion + crash with select name_const('test', now());
The NAME_CONST function is required to work correctly with constants only.
When executed with functions that return types other than those returned by
Item::field_type (string, int, decimal, or real), the result gets cast to
one of those types. This cannot happen for constants.
Fixed by only allowing constants as arguments to NAME_CONST.

33fc4ad4e1 Fixed bug #30120.
SP with local variables with non-ASCII names crashed the server.

The server replaces SP local variable names with NAME_CONST calls
when putting statements into the binary log. It used UTF8-encoded
item names as variable names for the replacement inside NAME_CONST
calls. However, statement string may be encoded by any
known character set by the SET NAMES statement.
The server used byte length of UTF8-encoded names to increment
the position in the query string that led to array index overrun.


sql/item.cc:
  Fixed bug #30120.
  The Item_splocal class constructor has been modified to
  accept new parameter `len_in_q': the byte length of
  variable name in the query string.
sql/item.h:
  Fixed bug #30120.
  The Item_splocal class has been modified to keep new

  The subst_spvars function has been modified to increment
  position in the query string by the lengths of not
  encoded variable names instead of byte length of names
  encoded to UTF-8.
sql/sql_yacc.yy:
  Fixed bug #30120.
  The simple_ident rule action has been modified to
  pass the byte length of the local variable name token

d27bf14ed7 Bug #29878 Garbage data generation when executing SESSION_USER() on a slave.
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,

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/t/trigger-trans.test:

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_view.cc:

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).

360a5ebc37 Remove typedef st_table_list TABLE_LIST and always use name 'TABLE_LIST'.
The need arose when working on Bug 26141, where it became
necessary to replace TABLE_LIST with its forward declaration in a few
headers, and this involved a lot of s/TABLE_LIST/st_table_list/.
Although other workarounds exist, this patch is in line
with our general strategy of moving away from typedef-ed names.
Sometime in future we might also rename TABLE_LIST to follow the
coding style, but this is a huge change.

5d88b654ed Fixed bug #29392.
This bug may manifest itself for select queries over a multi-table view
that includes an ORDER BY clause in its definition. If the select list of 
the query contains references to the same view column with different
aliases the names of the columns in the result output will be nevertheless
the same, coinciding with one of the alias.

The bug happened because the method Item_ref::get_tmp_table_item that
was inherited by the class Item_direct_view_ref ignored the fact that
the name of the view column reference must be inherited by the fields
of the temporary table that was created in order to get the result rows

925c33db65 Fix for BUG#10491: Server returns data as charset binary
SHOW CREATE TABLE or SELECT FROM I_S.

Actually, the bug discovers two problems:
  - the original query is not preserved properly. This is the problem
    of BUG#16291;
  - the resultset of SHOW CREATE TABLE statement is binary.

This patch fixes the second problem for the 5.0.

Both problems will be fixed in 5.1.

sql/item.h:

  because for views and base tables utf8 is the character set
  in which their definition is stored. For system constants
  it's the default character set, and for other objects
  (routines, triggers), no character set is stored, and
  therefore no character set is known, so returning utf8
  is just as good as any non-binary character set.
  This latter problem is fixed in 5.1 by 16291. In 5.1
  we will return the "real" character set.

18310fabf4 Bug#28763: Selecting geometry fields in UNION caused server crash.
This bug was introduced by the fix for the bug#27300. In this fix a section
of code was added to the Item::tmp_table_field_from_field_type method.
This section intended to create Field_geom fields for the Item_geometry_func
class and its descendants. In order to get the geometry type of the current
item it casted "this" to the Item_geometry_func* type. But the
Item::tmp_table_field_from_field_type method is also used for creation of
fields for UNION and in this case this method is called for an object of the

Now the Item::tmp_table_field_from_field_type method correctly works when it's
called for both the Item_type_holder and the Item_geometry_func classes.
The new geometry_type variable is added to the Item_type_holder class.
The new method called get_geometry_type is added to the Item_field

Item_field and the Field_geom classes and fails an assert for other Field
descendants.

5b3b80b44f Fix for bug #28464: a string argument to 'limit ?' PS - replication fails
Problem: we may get syntactically incorrect queries in the binary log 
if we use a string value user variable executing a PS which 
contains '... limit ?' clause, e.g.
prepare s from "select 1 limit ?"; 
set @a='qwe'; execute s using @a;
  
Fix: raise an error in such cases.

99bde6d9ec Bug#27759: Wrong DATE/DATETIME comparison in LEAST()/GREATEST() functions.
The LEAST/GREATEST functions compared DATE/DATETIME values as
strings which in some cases could lead to a wrong result.

A new member function called cmp_datetimes() is added to the
Item_func_min_max class. It compares arguments in DATETIME context
and returns index of the least/greatest argument.
The Item_func_min_max::fix_length_and_dec() function now detects when
arguments should be compared in DATETIME context and sets the newly
added flag compare_as_dates. It indicates that the cmp_datetimes() function
should be called to get a correct result.
Item_func_min_max::val_xxx() methods are corrected to call the
cmp_datetimes() function when needed.
Objects of the Item_splocal class now stores and reports correct original
field type.

7bb6a72593 Bug#27590: Wrong DATE/DATETIME comparison.
DATE and DATETIME can be compared either as strings or as int. Both
methods have their disadvantages. Strings can contain valid DATETIME value
but have insignificant zeros omitted thus became non-comparable with
other DATETIME strings. The comparison as int usually will require conversion
from the string representation and the automatic conversion in most cases is
carried out in a wrong way thus producing wrong comparison result. Another
problem occurs when one tries to compare DATE field with a DATETIME constant.
The constant is converted to DATE losing its precision i.e. losing time part.

This fix addresses the problems described above by adding a special
DATE/DATETIME comparator. The comparator correctly converts DATE/DATETIME
string values to int when it's necessary, adds zero time part (00:00:00)
to DATE values to compare them correctly to DATETIME values. Due to correct
conversion malformed DATETIME string values are correctly compared to other
DATE/DATETIME values.

As of this patch a DATE value equals to DATETIME value with zero time part.
For example '2001-01-01' equals to '2001-01-01 00:00:00'.

The compare_datetime() function is added to the Arg_comparator class.
It implements the correct comparator for DATE/DATETIME values.
Two supplementary functions called get_date_from_str() and get_datetime_value()
are added. The first one extracts DATE/DATETIME value from a string and the
second one retrieves the correct DATE/DATETIME value from an item.
The new Arg_comparator::can_compare_as_dates() function is added and used
to check whether two given items can be compared by the compare_datetime()
comparator.
Two caching variables were added to the Arg_comparator class to speedup the
DATE/DATETIME comparison.
One more store() method was added to the Item_cache_int class to cache int
values.
The new is_datetime() function was added to the Item class. It indicates
whether the item returns a DATE/DATETIME value.

1cf3b96513 Bug#27321: Wrong subquery result in a grouping select.
The Item_outer_ref class based on the Item_direct_ref class was always used
to represent an outer field. But if the outer select is a grouping one and the 
outer field isn't under an aggregate function which is aggregated in that
outer select an Item_ref object should be used to represent such a field.
If the outer select in which the outer field is resolved isn't grouping then
the Item_field class should be used to represent such a field.
This logic also should be used for an outer field resolved through its alias
name.

Now the Item_field::fix_outer_field() uses Item_outer_field objects to
represent aliased and non-aliased outer fields for grouping outer selects
only.
Now the fix_inner_refs() function chooses which class to use to access outer
field - the Item_ref or the Item_direct_ref. An object of the chosen class
substitutes the original field in the Item_outer_ref object.
The direct_ref and the found_in_select_list fields were added to the
Item_outer_ref class.

9c89dd654e Bug #24484:
To correctly decide which predicates can be evaluated with a given table
the optimizer must know the exact set of tables that a predicate depends 
on. If that mask is too wide (refer to non-existing tables) the optimizer
can erroneously skip a predicate.
One such case of wrong table usage mask were the aggregate functions.
The have a all-1 mask (meaning depend on all tables, including non-existent
ones).
Fixed by making a real used_tables mask for the aggregates. The mask is
constructed in the following way :
1. OR the table dependency masks of all the arguments of the aggregate.
2. If all the arguments of the function are from the local name resolution 
  context and it is evaluated in the same name resolution
  context where it is referenced all the tables from that name resolution 
  context are OR-ed to the dependency mask. This is to denote that an
  aggregate function depends on the number of rows it processes.
3. Handle correctly the case of an aggregate function optimization (such that
  the aggregate function can be pre-calculated and made a constant).

Made sure that an aggregate function is never a constant (unless subject of a 
specific optimization and pre-calculation).  

One other flaw was revealed and fixed in the process : references were 
not calling the recalculation method for used_tables of their targets.

91abf15ed2 Fixed bug #26738: incomplete string values in a result set column
when the column is to be read from a derived table column which 
was specified as a concatenation of string literals.
The bug happened because the Item_string::append did not adjust the
value of Item_string::max_length. As a result of it the temporary 
table column  defined to store the concatenation of literals was 
not wide enough to hold the whole value.

6da758c216 Fixed bug #26560.
The flag alias_name_used was not set on for the outer references
in subqueries. It resulted in replacement of any outer reference
resolved against an alias for a full field name when the frm 
representation of a view with a subquery was generated. 
If the subquery and the outer query referenced the same table in
their from lists this replacement effectively changed the meaning
of the view and led to wrong results for selects from this view. 

Modified several functions to ensure setting the right value of
the alias_name_used flag for outer references resolved against
aliases.
 


mysql-test/r/view.result:
  Added a test case for bug #26560.
mysql-test/t/view.test:
  Added a test case for bug #26560.
sql/item.cc:
  Fixed bug #26560.
  Made the function resolve_ref_in_select_and_group analyze the return
  value of the last parameter with the type of the name resolution for
  the submitted reference. If the reference has been resolved against 
  an alias name from select list then its flag alias_name_used is set on.
  Now this value is used in Item_field::fix_outer_field to initialize the flag
  when the item_ref object is created for an outer reference.
  Added a parameter for the second Item_ref::Item_ref constructor to initialize
  properly the flag alias_name_used. The default value of the parameter is FALSE.
  If this flag is set on at the creation of an object by this constructor it
  will never be changed. Corrected appropriately the Item_ref::set_properties
  function.
  The function Item_ref::print now prints alias name for an outer reference
  if the flag alias_name_used is set on.

  Fixed bug #26560.
  Added a parameter for the second Item_ref::Item_ref constructor to initialize

sql/sql_base.cc:
  Fixed bug #26560.
  Made the last parameter of the function find_field_in_tables return
  more detailed information on how the submitted item has been resolved.
  Now it says whether the item has been resolved
    against an alias name,
    or as a field name without alias,
    or as a field name hidden by alias, 
    or was resolved ignoring alias.
sql/sql_select.cc:
  Fixed bug #26560.
  Took into account the new type of the last parameter of the function
  find_item_in_list.

b114118ab7 Bug #19342:
Several problems here :
 1. The conversion to double of an hex string const item
 was not taking into account the unsigned flag.
 
 2. IN was not behaving in the same was way as comparisons
 when performed over an INT/DATE/DATETIME/TIMESTAMP column
 and a constant. The ordinary comparisons in that case 
 convert the constant to an INTEGER value and do int 
 comparisons. Fixed the IN to do the same.
 
 3. IN is not taking into account the unsigned flag when 
 calculating <expr> IN (<int_const1>, <int_const2>, ...).
 Extended the implementation of IN to store and process
 the unsigned flag for its arguments.

f8855142d7 Bug#23800: Outer fields in correlated subqueries is used in a temporary table
created for sorting.

Any outer reference in a subquery was represented by an Item_field object.
If the outer select employs a temporary table all such fields should be
replaced with fields from that temporary table in order to point to the 
actual data. This replacement wasn't done and that resulted in a wrong
subquery evaluation and a wrong result of the whole query.

Now any outer field is represented by two objects - Item_field placed in the
outer select and Item_outer_ref in the subquery. Item_field object is
processed as a normal field and the reference to it is saved in the
ref_pointer_array. Thus the Item_outer_ref is always references the correct
field. The original field is substituted for a reference in the
Item_field::fix_outer_field() function.

New function called fix_inner_refs() is added to fix fields referenced from
inner selects and to fix references (Item_ref objects) to these fields.

The new Item_outer_ref class is a descendant of the Item_direct_ref class.
It additionally stores a reference to the original field and designed to
behave more like a field.


sql/item.cc:
