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

sql/item_strfunc.cc:
  Touch the code that reads thd->db (cleanup).
sql/log_event.cc:
  While we are at it, replace direct access to thd->db with a method.
  Should simplify future conversion of THD::db to LEX_STRING.
sql/slave.cc:
  While we are at it, replace direct access to thd->db with a method.
  Should simplify future conversion of THD::db to LEX_STRING.
sql/slave.h:
  Remove a declaration for a method that is used only in one module.
sql/sp.cc:
  Rewrite sp_use_new_db: this is a cleanup that I needed in order to understand
  this function and ensure that it has no bugs.
sql/sp.h:
  Add a new declaration for sp_use_new_db (uses LEX_STRINGs) and a comment.
sql/sp_head.cc:
  - drop sp_name_current_db_new - a creator of sp_name class that was used
  when sp_name was created for an identifier without an explicitly initialized
  database. Now we pass thd->db to constructor of sp_name right in the 
  parser.
  - rewrite sp_head::init_strings: name->m_db is always set now
  - use the new variant of sp_use_new_db
  - we don't need to update thd->db with SP MEM_ROOT pointer anymore when
  parsing a stored procedure, as noone will refer to it (yes!)
sql/sp_head.h:
  - remove unneded methods and members
sql/sql_class.h:
  - introduce 3 THD  methods to work with THD::db:
    .set_db to assign the current database
    .reset_db to reset the current database (temporarily) or set it to NULL
    .opt_copy_db_to - to deep-copy thd->db to a pointer if it's not NULL
sql/sql_db.cc:
  While we are at it, replace direct access to thd->db with a method.
  Should simplify future conversion of THD::db to LEX_STRING.
sql/sql_insert.cc:
  - replace checks with asserts: table_list->db must be always set in the parser.
sql/sql_lex.h:
  - add a comment
sql/sql_parse.cc:
  - implement the invariant described in the changeset comment.
  - remove juggling with lex->sphead in SQLCOM_CREATE_PROCEDURE:
    now db_load_routine uses its own LEX object and doesn't damage the main
    LEX.
  - add DBUG_ASSERT(0) to unused "check_db_used"
sql/sql_table.cc:
  - replace a check with an assert (table_ident->db)
sql/sql_trigger.cc:
  While we are at it, replace direct access to thd->db with a method.
  Should simplify future conversion of THD::db to LEX_STRING.
sql/sql_udf.cc:
  - use thd->set_db instead of direct modification of to thd->db
sql/sql_view.cc:
  - replace a check with an assert (view->db)
sql/sql_yacc.yy:
  - make sure that we always copy table->db or name->db or ident->db or
    select_lex->db from thd->db if the former is not set. If thd->db
    is not set but is accessed, return an error.
sql/tztime.cc:
  - be nice, never copy thd->db by pointer.

6e80e9a4f9 Fixed bug#15962: CONCAT() in UNION may lead to a data trucation.
To calculate its max_length the CONCAT() function is simply sums max_lengths
of its arguments but when the collation of an argument differs from the 
collation of the CONCAT() max_length will be wrong. This may lead to a data
truncation when a tmp table is used, in UNIONS for example.

The Item_func_concat::fix_length_and_dec() function now recalculates the 
max_length of an argument when the mbmaxlen of the argument differs from the
mbmaxlen of the CONCAT().

fd7d4d7429 Fixed bug#15351: Wrong collation used for comparison of md5() and sha()
argument can lead to a wrong result.

md5() and sha() functions treat their arguments as case sensitive strings.
But when they are compared their arguments were compared as a case
insensitive strings which leads to two functions with different arguments
and thus different results to being identical. This can lead to a wrong
decision made in the range optimizer and thus lead to a wrong result set.

Item_func_md5::fix_length_and_dec() and Item_func_sha::fix_length_and_dec()
functions now set binary collation on their arguments.

1991a87d83 Fixed bug#16716: subselect in concat() may lead to a wrong result.
The Item_func_concat::val_str() function tries to make as less re-allocations
as possible. This results in appending strings returned by 2nd and next
arguments to the string returned by 1st argument if the buffer for the first
argument has enough free space. A constant subselect is evaluated only once 
and its result is stored in an Item_cache_str. In the case when the first
argument of the concat() function is such a subselect Item_cache_str returns
the stored value and Item_func_concat::val_str() append values of other
arguments to it. But for the next row the value in the Item_cache_str isn't
restored because the subselect is a constant one and it isn't evaluated second
time. This results in appending string values of 2nd and next arguments to the 
result of the previous Item_func_concat::val_str() call.

The Item_func_concat::val_str() function now checks whether the first argument 
is a constant one and if so it doesn't append values of 2nd and next arguments
to the string value returned by it.

0ce12f70ed Reviewing new pushed code
- CHAR() now returns binary string as default
- CHAR(X*65536+Y*256+Z) is now equal to CHAR(X,Y,Z) independent of the character set for CHAR()
- Test for both ETIMEDOUT and ETIME from pthread_cond_timedwait()
  (Some old systems returns ETIME and it's safer to test for both values
   than to try to write a wrapper for each old system)
- Fixed new introduced bug in NOT BETWEEN X and X
- Ensure we call commit_by_xid or rollback_by_xid for all engines, even if one engine has failed
- Use octet2hex() for all conversion of string to hex
- Simplify and optimize code

  Bar will shortly add the following syntax:
  CHAR(.... USING character_set)
  and ensure that
  CONVERT(CHAR(....) USING utf8) cuts not legal utf8 strings
  Use ocet2hex()
sql/item_strfunc.h:
  CHAR() now returns a binary string
sql/log_event.cc:
  Use octet2hex()

17feba98d4 Fix for bug #13407 "Remote connecting crashes server" and couple of similar
problems which were introduced during work on WL#2787 "Add view definer/owner
to the view definition (.frm) to check privileges on used tables and stored
routines when using a VIEW."

In some cases it is better to use value from Security_context::host_or_ip
instead of value from Security_context::host since the latter can be NULL
in certain situations (When we can't resolve hostname or we have not done
this yet).

    or we have not done this yet. Reverted back to old code).

      basically this: 
      select substring_index('the king of the the hill', 'the', -2) to not work.
      The first iteration, offset would be initialised to 24, then strstr would 
      point at 'the king of the the* hill' ('*'means right before the 
      character following), returning a offset of 16. The for loop would then 
      decrement offset by two (3 - 1), to 14, now pointing at 
      "the king of th*e the hill", _skipping_ past the 'e' in the second to last
      'the', and therefore strstr would never have a chance of matching the 
      second to last 'the', then moving on to the 'the' at the begginning of the 
      string!
      In a nutshell, offset was being decremented by too great a value, preventing
      the second to last 'the' from being ever found, hence the result of 
      'king of the the hill' from the query that is reported in the bug report

  Bug#12351
  CONCAT with USER()/DATEBASE() and
  a column gets strange results.
  Mark created Item_str as constant, so CONCAT
  cannot reuse it for optimization purposes.

16c4593089 BUG 11104 (same as changeset 1.1891 on the 5.0 tree, but realised this
needed to be fixed in earlier versions)
Fixed the iteration of how substrings are handled with negative indexes in 
SUBSTRING_INDEX


mysql-test/r/func_str.result:
  New results for the fix to substring_index
mysql-test/t/func_str.test:
  Added tests for fix to substring_index, various lenth search patterns. Also included
  are the queuries the user who reported the bug listed in the bug report
