A race condition in the integration between MyISAM and the query cache code 
caused the query cache to fail to invalidate itself on concurrently inserted
data.

This patch fix this problem by using the existing handler interface which, upon
each statement cache attempt, compare the size of the table as viewed from the 
cache writing thread and with any snap shot of the global table state. If the
two sizes are different the global table size is unknown and the current
statement can't be cached.

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.

fails if a database is not selected prior.

The problem manifested itself when a user tried to
create a routine that had non-fully-qualified identifiers in its bodies
and there was no current database selected.

This is a regression introduced by the fix for Bug 19022:

The patch for Bug 19022 changes the code to always produce a warning
if we can't resolve the current database in the parser. 
In this case this was not necessary, since even though the produced
parsed tree was incorrect, we never re-use sphead
that was obtained at first parsing of CREATE PROCEDURE.
The sphead that is anyhow used is always obtained through db_load_routine,
and there we change the current database to sphead->m_db before
calling yyparse.

The idea of the fix is to resolve the current database directly using 
lex->sphead->m_db member when parsing a stored routine body, when
such is present.

This patch removes the need to reset the current database
when loading a trigger or routine definition into SP cache.
The redundant code will be removed in 5.1.

'No database selected' is reported when calling stored procedures

Remove the offending warning introduced by the fix for Bug
25082
This minimal patch relies on the intrinsic knowledge of the fact that
mysql_change_db is never called with 'force_switch' set to TRUE
when such a warning may be needed:
 * every stored routine belongs to a database (unlike, e.g., a 
user defined function, which does not), so if we're activating the
database of a stored routine, it can never be NULL.
Therefore, this branch is never called for activation.
 * if we're restoring the 'old' current database after routine
execution is complete, we should not issue a warning, since it's OK to 
call a routine without having previously selected the current database.

TODO: 'force_switch' is an ambiguous flag, since we do not actually
have to 'force' the switch in case of stored routines at all.
When we activate the routine's database, we should perform
all the checks as in case of 'use db', and so we already do (in this
case 'force_switch' is unused).
When we load a routine into cache, we should not use mysql_change_db
at all, since there it's enough to call thd->reset_db(). We
do it this way for triggers, but code for routines is different (wrongly). 

TODO: bugs are lurking in replication, since it bypasses mysql_change_db
and calls thd->[re_]set_db to set the current database.
The latter does not change thd->db_charset, thd->sctx->db_access
and thd->variables.collation_database (and this may have nasty side
effects).

These todo items are to be addressed in a separate patch, if at all.

spaces.

When the my_strnncollsp_simple function compares two strings and one is a prefix
of another then this function compares characters in the rest of longer key
with the space character to find whether the longer key is greater or less.
But the sort order of the collation isn't used in this comparison. This may
lead to a wrong comparison result, wrongly created index or wrong order of the
result set of a query with the ORDER BY clause.

Now the my_strnncollsp_simple function uses collation sort order to compare
the characters in the rest of longer key with the space character.

query / no aggregate of subquery
 The optimizer counts the aggregate functions that 
 appear as top level expressions (in all_fields) in 
 the current subquery. Later it makes a list of these
 that it uses to actually execute the aggregates in
 end_send_group().
 That count is used in several places as a flag whether
 there are aggregates functions.
 While collecting the above info it must not consider
 aggregates that are not aggregated in the current 
 context. It must treat them as normal expressions 
 instead. Not doing that leads to incorrect data about
 the query, e.g. running a query that actually has no
 aggregate functions as if it has some (and hence is
 expected to return only one row).
 Fixed by ignoring the aggregates that are not aggregated
 in the current context. 
 One other smaller omission discovered and fixed in the 
 process : the place of aggregation was not calculated for
 user defined functions. Fixed by calling 
 Item_sum::init_sum_func_check() and 
 Item_sum::check_sum_func() as it's done for the rest of 
 the aggregate functions.

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.

  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.

  A table with maximum number of key segments and maximum length key name
  would have a corrupted .frm file, due to an incorrect calculation of the
  complete key length.  Now the key length is computed correctly (I hope) :-)
  
  MyISAM would reject a table with the maximum number of keys and the maximum
  number of key segments in all keys.  It would allow one less than this total
  maximum.  Now MyISAM accepts a table defined with the maximum.  (This is a
  very minor issue.)

Sometimes special 0 ENUM values was ALTERed to normal
empty string ENUM values.

Special 0 ENUM value has the same string representation
as normal ENUM value defined as '' (empty string).
The do_field_string function was used to convert
ENUM data at an ALTER TABLE request, but this
function doesn't care about numerical "indices" of
ENUM values, i.e. do_field_string doesn't distinguish
a special 0 value from an empty string value.

A new copy function called do_field_enum has been added to
copy special 0 ENUM values without conversion to an empty
string.

a lookup into a BINARY index by a key ended with spaces. It caused
an assertion abort for a debug version and wrong results for non-debug
versions.

The problem occurred because the function _mi_pack_key stripped off 
the trailing spaces from binary search keys while the function _mi_make_key
did not do it when keys were inserted into the index.

Now the function _mi_pack_key does not remove the trailing spaces from
search keys if they are of the binary type.

If one sets MYSQL_READ_DEFAULTS_FILE and MYSQL_READ_DEFAULT_GROUP options
after mysql_real_connect() called with that MYSQL instance,
these options will affect next mysql_reconnect then.
As we use a copy of the original MYSQL object inside mysql_reconnect,
and mysql_real_connect frees options.my_cnf_file and _group strings,
we will free these twice when we execute mysql_reconnect with the
same MYSQL for the second time.

  LOCK TABLES takes a list of tables to lock. It may lock several 
  tables successfully and then encounter a tables that it can't lock, 
  e.g. because it's locked. In such case it needs to undo the locks on
  the already locked tables. And it does that. But it has also notified
  the relevant table storage engine handlers that they should lock.
  The only reliable way to ensure that the table handlers will give up
  their locks is to end the transaction. This is what UNLOCK TABLE 
  does : it ends the transaction if there were locked tables by LOCK 
  tables.
  It is possible to end the transaction when the lock fails in 
  LOCK TABLES because LOCK TABLES ends the transaction at its start 
  already. 
  Fixed by ending (again) the transaction when LOCK TABLES fails to
  lock a table.

the loose scan optimization for grouping queries was applied returned 
a wrong result set when the query was used with the SQL_BIG_RESULT
option.

The SQL_BIG_RESULT option forces to use sorting algorithm for grouping
queries instead of employing a suitable index. The current loose scan
optimization is applied only for one table queries when the suitable
index is covering. It does not make sense to use sort algorithm in this
case. However the create_sort_index function does not take into account
the possible choice of the loose scan to implement the DISTINCT operator
which makes sorting unnecessary. Moreover the current implementation of
the loose scan for queries with distinct assumes that sorting will
never happen. Thus in this case create_sort_index should not call
the function filesort.
