sql/sql_select.cc:
Safety fix for bug #13855 "select distinct with group by caused server crash"
The previous patch only removed the symptomps, this fix removed the cause of the problem
(Which was that not all hidden_fields was stored in the temporary table)

- Fixed tests
- Optimized new code
- Fixed some unlikely core dumps
- Better bug fixes for:
- #14397 - OPTIMIZE TABLE with an open HANDLER causes a crash
- #14850 (ERROR 1062 when a quering a view using a Group By on a column that can be null
The table opening process now works the following way:
- Create common TABLE_SHARE object
- Read the .frm file and unpack it into the TABLE_SHARE object
- Create a TABLE object based on the information in the TABLE_SHARE
object and open a handler to the table object
Other noteworthy changes:
- In TABLE_SHARE the most common strings are now LEX_STRING's
- Better error message when table is not found
- Variable table_cache is now renamed 'table_open_cache'
- New variable 'table_definition_cache' that is the number of table defintions that will be cached
- strxnmov() calls are now fixed to avoid overflows
- strxnmov() will now always add one end \0 to result
- engine objects are now created with a TABLE_SHARE object instead of a TABLE object.
- After creating a field object one must call field->init(table) before using it
- For a busy system this change will give you:
- Less memory usage for table object
- Faster opening of tables (if it's has been in use or is in table definition cache)
- Allow you to cache many table definitions objects
- Faster drop of table

Views are not yet cached; For the moment we only cache if a table is a view or not.
Faster implementation of find_temorary_table()
Replace 'wait_for_refresh()' with the more general function 'wait_for_condition()'

Creation and destruct of TABLE_SHARE objects that are common for many TABLE objects
The table opening process now works the following way:
- Create common TABLE_SHARE object
- Read the .frm file and unpack it into the TABLE_SHARE object
- Create a TABLE object based on the information in the TABLE_SHARE
object and open a handler to the table object
open_table_def() is written in such a way that it should be trival to add parsing of the .frm files in new formats
sql/table.h:
TABLE objects for the same database table now share a common TABLE_SHARE object
In TABLE_SHARE the most common strings are now LEX_STRING's
sql/unireg.cc:
Changed arguments to rea_create_table() to have same order as other functions
Call field->init(table) for new created fields
sql/unireg.h:
Added OPEN_VIEW
strings/strxnmov.c:

This makes usage of strxnmov() safer as most of MySQL code assumes that strxnmov() will create a null terminated string
The table opening process now works the following way:
- Create common TABLE_SHARE object
- Read the .frm file and unpack it into the TABLE_SHARE object
- Create a TABLE object based on the information in the TABLE_SHARE

Bug#14397 - OPTIMIZE TABLE with an open HANDLER causes a crash
Manual merge.
Version for 5.0.
It fixes three problems:
1. The cause of the bug was that we did not check the table version for
the HANDLER ... READ commands. We did not notice when a table was
replaced by a new one. This can happen during ALTER TABLE, REPAIR
TABLE, and OPTIMIZE TABLE (there might be more cases). I call the fix
for this problem "the primary bug fix".
2. mysql_ha_flush() was not always called with a locked LOCK_open.
Though the function comment clearly said it must.
I changed the code so that the locking is done when required. I call
the fix for this problem "the secondary fix".
3. In 5.0 (not in 4.1 or 4.0) DROP TABLE had a possible deadlock flaw in
concur with FLUSH TABLES WITH READ LOCK. I call the fix for this
problem "the 5.0 addendum fix".

Bug#14397 - OPTIMIZE TABLE with an open HANDLER causes a crash
Manual merge.
Version for 4.0.
It fixes two problems:
1. The cause of the bug was that we did not check the table version for
the HANDLER ... READ commands. We did not notice when a table was
replaced by a new one. This can happen during ALTER TABLE, REPAIR
TABLE, and OPTIMIZE TABLE (there might be more cases). I call the fix
for this problem "the primary bug fix".
2. mysql_ha_flush() was not always called with a locked LOCK_open.
Though the function comment clearly said it must.
I changed the code so that the locking is done when required. I call
the fix for this problem "the secondary fix".

This bug occurs when some trigger for table used by DML statement is created
or changed while statement was waiting in lock_tables(). In this situation
prelocking set which we have calculated becames invalid which can easily lead
to errors and even in some cases to crashes.
With proposed patch we no longer silently reopen tables in lock_tables(),
instead caller of lock_tables() becomes responsible for reopening tables and
recalculation of prelocking set.
mysql-test/t/trigger.test:
Added tests for bug #12704 "Server crashes during trigger execution".
Unfortunately these tests rely on the order in which tables are locked
by statement so they are non-determenistic and therefore should be disabled.
sql/lock.cc:
mysql_lock_tables():
Now instead of always reopening altered or dropped tables by itself
mysql_lock_tables() can notify upper level and rely on caller doing this.
sql/mysql_priv.h:
Now mysql_lock_tables() can either reopen deleted or altered tables by itself
or notify caller about such situation through 'need_reopen' argument and rely
on it in this.
Also lock_tables() has new 'need_reopen' out parameter through which it
notifies caller that some tables were altered or dropped so he needs to reopen
them (and rebuild prelocking set some triggers may change or simply appear).
sql/sp.cc:
sp_add_used_routine():
To be able to restore LEX::sroutines_list to its state right after parsing
we now adjust LEX::sroutines_list_own_last/sroutines_list_own_elements when
we add directly used routine.
sp_remove_not_own_routines():
Added procedure for restoring LEX::sroutines/sroutines_list to their state
right after parsing (by throwing out non-directly used routines).
sp_cache_routines_and_add_tables_for_view()/sp_update_stmt_used_routines():
We should use LEX::sroutines_list instead of LEX::sroutines as source of
routines used by view, since LEX::sroutines is not availiable for view
on second attempt to open it (see comment in open_tables() about it).
sql/sp.h:
sp_remove_not_own_routines():
Added procedure for restoring LEX::sroutines/sroutines_list to their state
right after parsing (by throwing out non-directly used routines).
sql/sp_head.cc:
Removed assert which is no longer always true.
sql/sql_base.cc:
reopen_table():
When we re-open table and do shallow copy of TABLE object we should adjust
pointers to it in associated Table_triggers_list object. Removed nil
operation.
open_tables():
Now this function is able to rebuild prelocking set for statement if it is
needed. It also correctly handles FLUSH TABLES which may occur during its
execution.
lock_tables():
Instead of allowing mysql_lock_tables() to silently reopen altered or dropped
tables let us notify caller and rely on that it will do reopen itself.
This solves the problem when trigger suddenly appears or changed during
mysq_lock_tables().
close_tables_for_reopen():
Added routine for properly preparing for reopening of tables and recalculation
of set of prelocked tables.
sql/sql_handler.cc:
Here we let mysql_lock_tables() to reopen dropped or altered tables by itself.
sql/sql_insert.cc:
Here we let mysql_lock_tables() to reopen dropped or altered tables by itself.
sql/sql_lex.cc:
LEX:
Added 'sroutines_list_own_last' and 'sroutines_list_own_elements' members
which are used for keeping state in which 'sroutines_list' was right after
statement parsing (and for restoring of this list to this state).
sql/sql_lex.h:
LEX:
Added 'sroutines_list_own_last' and 'sroutines_list_own_elements' members
which are used for keeping state in which 'sroutines_list' was right after
statement parsing (and for restoring of this list to this state).
Added chop_off_not_own_tables() method to simplify throwing away list
of implicitly used (prelocked) tables.
sql/sql_prepare.cc:
Now instead of silently reopening altered or dropped tables in
lock_tables() we notify caller and rely on that the caller will
reopen tables.
sql/sql_table.cc:
Here we let mysql_lock_tables() to reopen dropped or altered tables by itself.
sql/sql_trigger.cc:
Added Table_triggers_list::set_table() method to adjust Table_triggers_list
to new pointer to TABLE instance.
sql/sql_trigger.h:
Added Table_triggers_list::set_table() method to adjust Table_triggers_list
to new pointer to TABLE instance.
sql/sql_update.cc:
Now instead of silently reopening altered or dropped tables in
lock_tables() we notify caller and rely on that the caller will
reopen tables.
This bug occurs when some trigger for table used by DML statement is created
or changed while statement was waiting in lock_tables(). In this situation

result set".
To enable full access to contents of I_S tables from stored functions
or statements that use them, we manipulate with thread's open tables
state and ensure that we won't cause deadlock when we open tables by
ignoring flushes and name-locks.
Building of contents of I_S.TABLES no longer requires locking of tables
since we use use handler::info() method with HA_STATUS_AUTO flag instead
of handler::update_auto_increment() for obtaining information about
auto-increment values. But this also means that handlers have to implement
support for HA_STATUS_AUTO flag (particularly InnoDB needs it).
mysql-test/r/alter_table.result:
Updated test results. This change was caused by the fact that now when
we build contents of I_S tables (and thus output of SHOW INDEX) we
don't use instances of tables which may be already opened and locked
by thread (we always use new instance).
mysql-test/r/information_schema.result:
Added test which checks how information about current auto-increment value for
table is reported in INFORMATION_SCHEMA.TABLES view.
mysql-test/r/sp.result:
Added test for bug #10055 "Using stored function with information_schema causes
empty result set".
mysql-test/t/information_schema.test:
Added test which checks how information about current auto-increment value for
table is reported in INFORMATION_SCHEMA.TABLES view.
mysql-test/t/sp.test:
Added test for bug #10055 "Using stored function with information_schema causes
empty result set".
sql/mysql_priv.h:
close_thread_tables():
Get rid of 'stopper' argument which is no longer used. Now when we need
to open and then close some table without touching tables which are already
opened we use THD::reset_n/restore_backup_open_tables_state() methods.
open_tables()/open_normal_and_derived_tables():
Added 'flags' argument to be able open tables even if some has done
a flush or hold namelock on them.
sql/sp.cc:
close_proc_table/open_proc_table_for_read/db_find_routine():
Replaced push_open_tables_state/pop_open_tables_state() methods which
were saving/restoring current open tables state in/from THD::open_state_list
with reset_n_backup_open_tables_state/restore_backup_open_tables_state()
methods which assume that backup storage for this state is allocated on
stack (or elsewhere) by their caller.
open_proc_table_for_read():
Since now we can have several open tables states stacked up we can't rely
rely on checking whether we have some tables open in previous state.
Instead we always assume that some tables are open and we need to ignore
flush while locking mysql.proc. We don't really need
MYSQL_LOCK_IGNORE_GLOBAL_READ_LOCK in this case since we open mysql.proc table
only for reading.
sql/sp.h:
Added declarations of open_proc_table_for_read()/close_proc_table() to be
able to use them in sql_show.cc.
sql/sql_base.cc:
close_thread_tables():
Get rid of 'stopper' argument which is no longer used. Now when we need
to open and then close some table without touching tables which are already
opened we use THD::reset_n/restore_backup_open_tables_state() methods.
open_tables()/open_normal_and_derived_tables():
Added 'flags' argument to be able open tables even if some has done
a flush or hold namelock on them.
sql/sql_class.cc:
Open_tables_state, THD:
Replaced push_open_tables_state/pop_open_tables_state() methods which
were saving/restoring current open tables state in/from THD::open_state_list
with reset_n_backup_open_tables_state/restore_backup_open_tables_state()
methods which assume that backup storage for this state is allocated on

sql/sql_class.h:
Open_tables_state, THD:

open_tables()/open_normal_and_derived_tables():
Added 'flags' argument to be able open tables even if some has done

sql/sql_show.cc:
get_all_tables():
Now we use THD::reset_n_/restore_backup_open_tables_state() for
saving/restoring open tables state instead of working with it directly
(This also allows us to have proper content of I_S system tables in
statements with stored functions and in stored functions). We also
ignore possible flushes when opening tables (we may create deadlock
otherwise). Also we do all needed manipulations with LEX in this function
and not in get_schema_tables_result() now.
get_schema_tables_record():
Let us use handler::info() method with HA_STATUS_AUTO flag for obtaining
information about table's auto-increment value. This allows to avoid locking
of tables which is needed when we use handler::update_auto_increment() method.
fill_schema_proc():
Now we use open_proc_table_for_read/close_proc_table() for access to
mysql.proc table (so we won't cause deadlock if we already have some
tables open and locked, this also allows us to have proper content in
ROUTINES system table in statements using stored functions/in stored
functions).
get_schema_tables_result():
Moved all manipulations with Open_tables_state and LEX needed for
safe opening of tables to ST_SCHEMA_TABLE::fill_table functions
(i.e. get_all_tables() and fill_schema_proc()).
sql/sql_update.cc:
open_tables()/open_normal_and_derived_tables():
Added 'flags' argument to be able open tables even if some has done

allocate_view_names flag of insert_fields is removed.
The purpose of this variable was to amend the case when a view
is replaced with a base table between subsequent executions of a prepared

of the view. If allocate_view_names was set,
all the references to the view expressions were replaced with Item_field's
which in turn could have been resolved by their names.
But this approach doesn't work for other reasons, so let's not try
to help what must be solved by TDC.

Fix test results: now LIMIT can contain placeholders.
mysql-test/r/ps_5merge.result:
Fix test results: now LIMIT can contain placeholders.
mysql-test/r/ps_6bdb.result:
Fix test results: now LIMIT can contain placeholders.
mysql-test/r/ps_7ndb.result:
Fix test results: now LIMIT can contain placeholders.
mysql-test/t/ps.test:
Add basic test coverage for LIMIT ?, ?.
sql/item.h:
Add a short-cut for (ulonglong) val_int() to Item.
Add a constructor to Item_int() that accepts ulonglong.
Simplify Item_uint constructor by using the c-tor above.
sql/item_subselect.cc:
Now select_limit has type Item *.
We can safely create an Item in Item_exists_subselect::fix_length_and_dec():
it will be allocated in runtime memory root and freed in the end of
execution.
sql/sp_head.cc:
Add a special initalization state for stored procedures to
be able to easily distinguish the first execution of a stored procedure
from prepared statement prepare.
sql/sql_class.h:
Introduce new state 'INITIALIZED_FOR_SP' to be able to easily distinguish
the first execution of a stored procedure from prepared statement prepare.
sql/sql_derived.cc:
- use unit->set_limit() to set unit->select_limit_cnt, offset_limit_cnt
evreryplace. Add a warning about use of set_limit in
mysql_derived_filling.
sql/sql_error.cc:
- use unit->set_limit() to set unit->select_limit_cnt, offset_limit_cnt
evreryplace.
- this change is also aware of bug#11095 "show warnings limit 0 returns
all rows instead of zero rows", so the one who merges the bugfix from
4.1 can use local version of sql_error.cc.
sql/sql_handler.cc:
- use unit->set_limit() to initalize
unit->select_limit_cnt,offset_limit_cnt everyplace.
sql/sql_lex.cc:
Now ST_SELECT_LEX::select_limit, offset_limit have type Item *
sql/sql_lex.h:
Now ST_SELECT_LEX::select_limit, offset_limit have type Item *
sql/sql_parse.cc:
- use unit->set_limit() to initalize
unit->select_limit_cnt,offset_limit_cnt everyplace.
- we can create an Item_int to set global limit of a statement:
it will be created in the runtime mem root and freed in the end of
execution.
sql/sql_repl.cc:
Use unit->set_limit to initialize limits.
sql/sql_select.cc:
- select_limit is now Item* so the proper way to check for default value
is to compare it with NULL.
sql/sql_union.cc:
Evaluate offset_limit_cnt using the new type of ST_SELECT_LEX::offset_limit
sql/sql_view.cc:
Now ST_SELECT_LEX::select_limit, offset_limit have type Item *
sql/sql_yacc.yy:
Add grammar support for LIMIT ?, ? clause.
error for LIMIT placeholder".
The patch adds grammar support for LIMIT ?, ? and changes the
type of ST_SELECT_LEX::select_limit,offset_limit from ha_rows to Item*,
so that it can point to Item_param.
