           redefining trigger
      
The 'table->auto_increment_field_not_null' flag is only valid within
processing of a single row, and should be set to FALSE before
navigating to the next row, or exiting the operation.
      
This bug was caused by an SQL error occuring while executing a trigger
after the flag had been set, so the normal resetting was bypassed.
The table object was then returned to the table share's cache in
a dirty condition.   When the table object was reused, an assert
caught that the flag was set.
      
This patch explicitly clears the flag on error/abort.

The fix for Bug #38124 introuced a bug. If the value given 
for a set_var exceeded the length of the temporary buffer,
we would read behind the end of the buffer.  Using 
c_ptr_safe(), instead of c_ptr(), ensures that we won't
read beyond the buffer limit

In the partition handler code, LOCK_open and share->LOCK_ha_data
are acquired in the wrong order in certain cases.  When doing a
multi-row INSERT (i.e a INSERT..SELECT) in a table with auto-
increment column(s). the increments must be in a monotonically
continuous increasing sequence (i.e it can't have "holes"). To
achieve this, a lock is held for the duration of the operation.
share->LOCK_ha_data was used for this purpose.
            
Whenever there was a need to open a view _during_ the operation
(views are not currently pre-opened the way tables are), and
LOCK_open was grabbed, a deadlock could occur.  share->LOCK_ha_data
is other places used _while_ holding LOCK_open.
            
A new mutex was introduced in the HA_DATA_PARTITION structure,
for exclusive use of the autoincrement data fields, so we don't
need to overload the use of LOCK_ha_data here.
            
A module test case has not been supplied, since the problem occurs
as a result of a race condition, and testing for this condition 
is thus not deterministic.   Testing for it could be done by
setting up a test case as described in the bug report.

                  
When assigning the new string value to the variable, the
Item::str_value member was used.  This is not according to
the protocol.  str_value is an internal member used for
temporary assignments, and is not consistently set for all
string operations.  It is set for constant strings, so it would
work in these cases, but not for string functions (concat,
substr, etc.)
                  
The correct approach is to use Item::val_str(..) to evaluate
and retrieve the string.

mysys/my_largepage.c:
  Fix a typo.

Bug #47274 assert in open_table on CREATE TABLE <already existing>

The problem was an assertion during execution of CREATE TABLES. 
This assertion would occur if INSERT DELAYED or REPLACE DELAYED
were used to update a table containing an AUTO_INCREMENT column
and if the inserted row had a user-supplied value for that column.
Any CREATE TABLE statement (including CREATE TABLE SELECT and
CREATE TABLE LIKE) trying to create the same table and 
which followed the INSERT/REPLACED would cause the assertion.

The problem was only noticeable on debug builds of the server
and not present in the mysql-5.1 tree.

The cause of the problem was that the code for delayed insert did
not properly reset the TABLE->auto_increment_if_null flag after 
The flag is used to indicate that a non-null value of an auto_increment field
has been provided by the user or retrieved from a current record.
Open_tables() contains an assertion that tests this flag, and this
was triggered by CREATE TABLE.

This patch fixes the problem by resetting the auto_increment_if_null
field to FALSE once INSERT/REPLACE DELAYED has updated the table, 
similar to what is done already for regular INSERT statements.

Test case added to delayed.test.

Server was unable to find existing or explicitly created supporting
index for foreign key if corresponding statement clause used field
names in case different than one used in key specification and created
yet another supporting index.
In cases when name of constraint (and thus name of generated index)
was the same as name of existing/explicitly created index this led
to duplicate key name error.

The problem was that unlike all other code Key_part_spec::operator==()
compared field names in case sensitive fashion. As result routines
responsible for getting rid of redundant generated supporting indexes
for foreign key were not working properly for versions of field names
using different cases.

  The problem was that directories with no permission (000) files

  On UNIX, 000-permission file is deleted perfectly, but other files
  are left in the directory.
  
  On Windows, 000-permission file is not deleted, but other files

storing and restoring information about foreign keys in the .FRM files and
properly displaying it in SHOW CREATE TABLE output and I_S tables.

The idea of this patch is to change type of Key_part_spec::field_name and
Key::name to LEX_STRING in order to avoid extra strlen() calls during
semantic analysis and statement execution, particularly, in code to be
implemented on the 2nd milestone of WL#148.

Note that since we are not using LEX_STRING everywhere yet (e.g. in
Create_field and KEY) and we want to limit scope of our changes we
have to do strlen() in places where we create Key and Key_part_spec
instances from objects using plain (char*) for strings. These calls
will go away during the process of further (char*) -> LEX_STRING
refactoring.

We have introduced these changes in 6.0 and backported them to 5.5
tree to make people aware of these changes as early as possible and
to simplify merges with mysql-fk and mysql-6.1-fk trees.

No test case is needed since this patch does not introduce any
user visible changes.

sql/sql_class.cc:
  Key_part_spec::field_name is now LEX_STRING. Adjusted code accordingly.
sql/sql_class.h:
  Changed type of Key_part_spec::field_name and Key::name to LEX_STRING in
  order to avoid extra strlen() calls in code responsible for semantic
  analysis and statement execution (e.g. in future code responsible for
  saving/restoring info about foreign keys).
sql/sql_lex.cc:
  Moved null_lex_str from sql_yacc.yy to sql_lex.cc and added its
  declaration to sql_lex.h to make it accessible in other SQL-layer
  modules (e.g. sql_parse.cc).
sql/sql_lex.h:
  Made null_lex_str accessible from outside of sql_lex.cc.
sql/sql_parse.cc:
  Key_part_spec::field_name and Key::name are now LEX_STRING. Adjusted
  code accordingly.
sql/sql_table.cc:
  Adjusted code to accomodate change of type to LEX_STRING for
  Key_part_spec::field_name and Key::name.
sql/sql_yacc.yy:
  Now Key::name and Key_part_spec::field_name are LEX_STRINGs. Adjusted
  grammar to be able properly initialize them. This should allow us to
  save on some strlen() calls during later stages of statement execution.
