If the user has specified --max-connections=N or --table-open-cache=M
options to the server, a warning could be given that some values were
recalculated, and table-open-cache could be assigned greater value.

Note that both warning and increase of table-open-cache were totally
harmless.

This patch fixes recalculation code to ensure that table-open-cache will
be never increased automatically and that a warning will be given only if
some values had to be decreased due to operating system limits.

No test case is provided because we neither can't predict nor control
operating system limits for maximal number of open files.

warnings in sql_trigger.cc and sql_view.cc".

According to the current version of C++ standard offsetof() macro
can't be used for non-POD types. So warnings were emitted when we
tried to use this macro for TABLE_LIST and Table_triggers_list
classes. Note that despite of these warnings it was probably safe
thing to do.

This fix tries to circumvent this limitation by implementing
custom version of offsetof() macro to be used with these
classes. This hack should go away once we will refactor
File_parser class.

Alternative approaches such as disabling this warning for
sql_trigger.cc/sql_view.cc or for the whole server were
considered less explicit. Also I was unable to find a way
to disable particular warning for particular _part_ of
file in GCC.


sql/parse_file.h:
  Introduced auxillary macro which can be used instead of offsetof()
  to get offsets of members in class for non-POD types without getting
  warnings (assuming that all instances of the class has same offsets
  for same members).
sql/sql_trigger.cc:
  Use my_offsetof() macro instead of standard offsetof() macro with
  Table_triggers_list class in order to avoid warnings (offsetof()
  cannot be used for non-POD types according to the standard).
sql/sql_view.cc:
  Use my_offsetof() macro instead of standard offsetof() macro with
  TABLE_LIST class in order to avoid warnings (offsetof() cannot
  be used for non-POD types according to the standard).

This patch reverts a change introduced by Bug 6951, which incorrectly
set thd->abort_on_warning for stored procedures.

As per internal discussions about the SQL_MODE=TRADITIONAL,
the correct behavior is to *not* abort on warnings even inside an INSERT/UPDATE
trigger.

Tests for Stored Procedures, Stored Functions, Triggers involving SQL_MODE
have been included or revised, to reflect the intended behavior.

When statement to be prepared contained CREATE PROCEDURE, CREATE FUNCTION
or CREATE TRIGGER statements with a syntax error in it, the preparation
would fail with syntax error message, but the memory could be corrupted.

The problem occurred because we switch memroot when parse stored
routine or trigger definitions, and on parse error we restored the
original memroot only after performing some memory operations.  In more
detail:
 - prepared statement would activate its own memory root to parse
   the definition of the stored procedure.
 - SP would reset this memory root with its own memory root to
   parse SP statements
 - a syntax error would happen
 - prepared statement would restore the original memory root
 - stored procedure would restore what it thinks was the original
   memory root, but actually was the statement memory root.
That led to double free - in destruction of the statement and in
a next call to mysql_parse().

The solution is to restore memroot right after the failed parsing.

sql/sql_parse.cc:
  On parse error if thd->lex->sphead is set we have to free sp_head object

  The change here is for safety, currently query_cache_abort() and
  lex->unit.cleanup() calls do not use current memroot.
sql/sql_prepare.cc:
  On parse error if thd->lex->sphead is set we have to free sp_head object

(COUNT(*) = 1) not working in SELECT inside prepared statement.
Note: the warning was introduced in 5.0 and 5.1, 4.1 is OK with the
original fix.

The problem was that in 5.0 and 5.1 clear() for group functions may
access hybrid_type member, and this member is initialized in
fix_fields().

So we should not call clear() from item cleanup() methods, as cleanup()
may be called for unfixed items.


sql/item_sum.cc:
  Do not call clear() from item cleanup() methods, as cleanup() may be
  called for unfixed items, and clear() assumes the item was fixed.

           should fail to create

The problem was that this type of errors was checked during view
creation, which doesn't happen when CREATE VIEW is a statement of
a created stored routine.

The solution is to perform the checks at parse time.  The idea of the
fix is that the parser checks if a construction just parsed is allowed
in current circumstances by testing certain flags, and this flags are
reset for VIEWs.

The side effect of this change is that if the user already have
such bogus routines, it will now get a error when trying to do

  SHOW CREATE PROCEDURE proc;

(and some other) and when trying to execute such routine he will get

  ERROR 1457 (HY000): Failed to load routine test.p5. The table mysql.proc is missing, corrupt, or contains bad data (internal code -6)

However there should be very few such users (if any), and they may
(and should) drop these bogus routines.

In a trigger or a function used in a statement it is possible to do
SELECT from a table being modified by the statement.  However,
encapsulation of such SELECT into a view and selecting from a view
instead of direct SELECT was not possible.

This happened because tables used by views (which in their turn
were used from functions/triggers) were not excluded from checks
in unique_table() routine as it happens for the rest of tables
added to the statement table list for prelocking.

With this fix we ignore all such tables in unique_table(), thus
providing consistency: inside a trigger or a functions SELECT from
a view may be used where plain SELECT is allowed.  Modification of
the same table from function or trigger is still disallowed.  Also,
this patch doesn't affect the case where SELECT from the table being
modified is done outside of function of trigger, such SELECTs are
still disallowed (this limitation and visibility problem when function
select from a table being modified are subjects of bug 21326).  See
also bug 22427.

The syntax of the CALL statement, to invoke a stored procedure, has been
changed to make the use of parenthesis optional in the argument list.
With this change, "CALL p;" is equivalent to "CALL p();".

While the SQL spec does not explicitely mandate this syntax, supporting it
is needed for practical reasons, for integration with JDBC / ODBC connectors.

Also, warnings in the sql/sql_yacc.yy file, which were not reported by Bison 2.1
but are now reported by Bison 2.2, have been fixed.

The warning found were:
bison -y -p MYSQL  -d --debug --verbose sql_yacc.yy

"unused value: $2" correspond to the $$=$1 assignment in the 1st {} block
in table_ref -> join_table {} {},
which does not procude a result ($$) for the rule but an intermediate $2
value for the action instead.
"unused value: $5" are similar, with $$ assignments in {} actions blocks
which are not for the final reduce.

procedures.  However, 4.1 had some bugs that were fixed in 5.0 by the
patch for bug#21726, and this patch is a backport of those fixes.
Namely, in 4.1 it fixes:

  - LAST_INSERT_ID(expr) didn't return value of expr (4.1 specific).

  - LAST_INSERT_ID() could return the value generated by current
    statement if the call happens after the generation, like in

      CREATE TABLE t1 (i INT AUTO_INCREMENT PRIMARY KEY, j INT);
      INSERT INTO t1 VALUES (NULL, 0), (NULL, LAST_INSERT_ID());

  - Redundant binary log LAST_INSERT_ID_EVENTs could be generated.
