e3d49f0c3f BUG#18819: DELETE IGNORE hangs on foreign key parent delete
If the error happens during DELETE IGNORE, nothing could be send to the
client, thus leaving it frozen expecting the reply.

The problem was that if some error occurred, it wouldn't be reported to
the client because of IGNORE, but neither success would be reported.

MySQL 4.1 would not freeze the client, but will report

  ERROR 1105 (HY000): Unknown error

instead, which is also a bug.

The solution is to report success if we are in DELETE IGNORE and some
non-fatal error has happened.


mysql-test/r/innodb_mysql.result:
  Add result for bug#18819: DELETE IGNORE hangs on foreign key parent
  delete.
mysql-test/t/innodb_mysql.test:
  Add test case for bug#18819: DELETE IGNORE hangs on foreign key parent

sql/sql_delete.cc:
  Report success if we have got an error, but we are in DELETE IGNORE, and
  the error is not fatal (if it is, it would be reported to the client).

1a793de9e4 Fix for bug#15228 "'invalid access to non-static data member'
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).

5bd58f3e00 Bug#20028 (Function with select return no data)
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.

(reposting approved patch, to work around source control issues, no review needed)

ef2d2165d1 BUG#21856: Prepared Statements: crash if bad create
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.

  Add result for bug#21856: Prepared Statements: crash if bad create.
mysql-test/t/ps.test:
  Add test case for bug#21856: Prepared Statements: crash if bad create.
sql/sql_parse.cc:
  On parse error if thd->lex->sphead is set we have to free sp_head object
  to restore statement memroot, if it was switched during parsing.
  
  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
  to restore statement memroot, if it was switched during parsing.

48cf65c037 BUG#23175 - MYISAM crash/repair failed during repair
Repair table could crash a server if there is not sufficient
memory (myisam_sort_buffer_size) to operate. Affects not only
repair, but also all statements that use create index by sort:
repair by sort, parallel repair, bulk insert.

Return an error if there is not sufficient memory to store at
least one key per BUFFPEK.

Also fixed memory leak if thr_find_all_keys returns an error.


myisam/sort.c:
  maxbuffer is number of BUFFPEK-s for repair. It is calculated
  as records / keys. keys is number of keys that can be stored
  in memory (myisam_sort_buffer_size). There must be sufficient
  memory to store both BUFFPEK-s and keys. It was checked
  correctly before this patch. However there is another
  requirement that wasn't checked: there must be sufficient
  memory for at least one key per BUFFPEK, otherwise repair
  by sort/parallel repair cannot operate.
  
  Return an error if there is not sufficient memory to store at
  least one key per BUFFPEK.
  
  Also fixed memory leak if thr_find_all_keys returns an error.

cc558cfba3 Fix for valgrind warning introduced by the fix for bug#21354:
(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.

841ea461ce Bug#21798: memory leak during query execution with subquery in column
list using a function
When executing dependent subqueries they are re-inited and re-exec() for 
each row of the outer context.
The cause for the bug is that during subquery reinitialization/re-execution,
the optimizer reallocates JOIN::join_tab, JOIN::table in make_simple_join()
and the local variable in 'sortorder' in create_sort_index(), which is
allocated by make_unireg_sortorder().
Care must be taken not to allocate anything into the thread's memory pool
while re-initializing query plan structures between subquery re-executions.
All such items mush be cached and reused because the thread's memory pool
is freed at the end of the whole query.
Note that they must be cached and reused even for queries that are not 
otherwise cacheable because otherwise it will grow the thread's memory 
pool every time a cacheable query is re-executed. 
We provide additional members to the JOIN structure to store references 
to the items that need to be cached.

6101fd25d0 Fixed bug #19579: at range analysis optimizer did not take into
account predicates that become sargable after reading const tables.
In some cases this resulted in choosing non-optimal execution plans.
Now info of such potentially saragable predicates is saved in
an array and after reading const tables we check whether this
predicates has become saragable.

decf9082fb Bug #22342: No results returned for query using max and group by
When using index for group by and range access the server isolates    
 a set of ranges based on the conditions over the key parts of the
 index used. Then it uses only the ranges over the GROUP BY fields to
 jump from one group to another. Since the GROUP BY fields may form a
 prefix over the index, we may use only a prefix of the ranges produced
 by the range optimizer.
 Each range contains a notion on whether it includes its border values.
 The problem is that when using a range prefix, the last range is open
 because it assumes that there is a range on the next keypart. Thus when
 we use a prefix range as it is, it excludes all border values.
 The solution is when ignoring the suffix of the range conditions 
 (to jump over the GROUP BY prefix only) the server must change the 
 remaining intervals so they always contain their borders, e.g. 
 if the whole range was :
 (1,-inf) <= (<group_by_col>,<min_max_arg_col>) < (1, 3) we must make
 (1) <= (<group_by_col>) <= (1) because (a,b) < (c1,c2) means :
 a < c1 OR (a = c1 AND b < c2).
