data": remove the fix for another bug (8807) that
added OUTER_REF_TABLE_BIT to all subqueries that used a placeholder
to prevent their evaluation at prepare. As this bit hanged in
Item_subselect::used_tables_cache for ever, a constant subquery with
a placeholder was never evaluated as such, which caused wrong
choice of the execution plan for the statement.
- to fix Bug#8807 backport a better fix from 5.0
- post-review fixes.
mysql-test/r/ps.result:
Bug#11458: test results fixed
mysql-test/t/ps.test:
- add a test case for Bug#11458 "Prepared statement with subselects return
random data"
sql/item.cc:
- remove unnecessary Item_param::fix_fields
- fix Item_param::set_null to set item_type accordingly (safety:
Item_param should behave like a basic constant).
sql/item.h:
Remove Item_param::fix_fields
sql/item_subselect.h:
Remove no more existing friend.
sql/mysql_priv.h:
Add UNCACHEABLE_PREPARE to mark all subqueries as uncacheable if
in statement prepare (backport from 5.0).
sql/sql_lex.h:
Comment fixed.
sql/sql_parse.cc:
If in statement prepare, mark all subqueries as uncacheable (backport
from 5.0)
sql/sql_prepare.cc:
Switch off the uncacheable flag from all subqueries after statement
prepare is done (backport from 5.0)

of stored routines definitions even if we already have some tables open and
locked. To avoid deadlocks in this case we have to put certain restrictions
on locking of mysql.proc table.
This allows to use stored routines safely under LOCK TABLES without explicitly
mentioning mysql.proc in the list of locked tables. It also fixes bug #11554
"Server crashes on statement indirectly using non-cached function".
mysql-test/r/sp-error.result:
Added test which checks that now we can read stored routines definitions
under LOCK TABLES even if we have not locked mysql.proc explicitly. Also
added check for restrictions which this ability puts on mysql.proc locking.
Updated test for bug #9566 to correspond this new situation.

sql/lock.cc:
get_lock_data():
To be able to open and lock for reading system tables like 'mysql.proc',
when we already have some tables opened and locked, and avoid deadlocks
we have to disallow write-locking of these tables with any other tables.
sql/mysql_priv.h:
open_table() has new parameter which allows to open table even if some-one
has done a flush or holding namelock on it.
sql/share/errmsg.txt:
Added error message saying that one cannot write-lock some of system tables
with any other tables.
sql/sp.cc:
open_proc_table_for_read()/close_proc_table():
Added functions to be able open and close mysql.proc table when we already
have some tables open and locked.
open_proc_table_for_update():
Added function to simplify opening of mysql.proc for updates.
db_find_routine_aux()/db_find_routine()/db_update_routine()/...
Moved responsibility for opening mysql.proc table from db_find_routine_aux()
one level up, since this level knows better which type of table access for
reading of for update it needs.
sp_function_exists():

open_unireg_entry():
Mark 'mysql.proc' as a system table which has special restrictions on its
locking, but thanks to them can be open and locked even if we already have
some open and locked.
sql/sql_class.cc:
Moved THD members holding information about open and locked tables to separate
Open_tables_state class to be able to save/restore this state easier.

sql/table.h:
Added TABLE_SHARE::system_table indicating that this table is system table
like 'mysql.proc' and we want to be able to open and read-lock it even when
we already have some tables open and locked (and because of this we have
to put some restrictions on write locking it).

When searching column to sort on, item was compared to field under view
column, but not the column itself. Because names of view column and underlaid
field may differ, it leads to possibly choosing wrong column for sorting on.
This patch makes Item_direct_view_ref::eq(Item *item,...) compare
item's name with it's own name proir to comparing to *ref item.

Fixed issue with 32bit systems giving warnings on bit shift (this is due to the fix by Jim to change to ha_rows). The error logic for opening a table was reworked after studing up on a reported issue. It has been reworked to create a share in all situations. The repair table will just have to figure everything out or toss its own error. The read only filesystem and permission denied problems were solved. Repair table code now rebuilds with the new optimize table extended code (so it no longer does the work itself).

crash if referencing a table" and several other related bugs.
Fix for bug #11834 "Re-execution of prepared statement with dropped function
crashes server." which was spotted during work on previous bugs.
Also couple of nice cleanups:
- Replaced two separate hashes for stored routines used by statement with one.
- Now instead of doing one pass through all routines used in statement for
caching them and then doing another pass for adding their tables to table
list, we do only one pass during which do both things.
mysql-test/r/sp-error.result:
Added test for bug #11834 "Re-execution of prepared statement with dropped
function crashes server" also covering handling of prepared statements
which use stored functions but does not require prelocking.
mysql-test/r/sp.result:
Updated test for LOCK TABLES with views in table list.
(Old version of statement used in this test will work ok now, since prelocking
algorithm was tuned and will lock only one multi-set of tables for each routine
even if this routine is used in several different views).
mysql-test/r/trigger.result:
Added several tests for triggers using tables.
mysql-test/t/sp-error.test:
Added test for bug #11834 "Re-execution of prepared statement with dropped
function crashes server" also covering handling of prepared statements
which use stored functions but does not require prelocking.
mysql-test/t/sp.test:
Updated comment about recursive views to reflect current situation.
Updated test for LOCK TABLES with views in table list.
(Old version of statement used in this test will work ok now, since prelocking
algorithm was tuned and will lock only one multi-set of tables for each routine
even if this routine is used in several different views).
mysql-test/t/trigger.test:
Added several tests for triggers using tables.
sql/item_func.cc:
Item_func_sp::cleanup():
By next statement execution stored function can be dropped or altered so
we can't assume that sp_head object for it will be still valid.
sql/sp.cc:
- Added Sroutine_hash_entry structure that represents element in the set of
stored routines used by statement or routine. We can't as before use
LEX_STRING for this purprose because we want link all elements of this set
in list.
- Replaced sp_add_to_hash() with sp_add_used_routine() which takes into account
that now we use one hash for stored routines used by statement instead of two
and which mantains list linking all elelemnts in this hash.
- Renamed sp_merge_hash() to sp_update_sp_used_routines().
- Introduced sp_update_stmt_used_routines() for adding elements to the set of
routines used by statement from another similar set for statement or routine.
This function will also mantain list linking elements of destination set.
- Now instead of one sp_cache_routines() function we have family of
sp_cache_routines_and_add_tables() functions which are also responsible for
adding tables used by routines being cached to statement table list. Nice
optimization - thanks to list linking all elements in the hash of routines
used by statement we don't need to perform several iterations over this hash
(as it was before in cases when we have added new elements to it).
sql/sp.h:
Added declarations of functions used for manipulations with set (hash) of stored
routines used by statement.
sql/sp_head.cc:
sp_name::init_qname():
Now sp_name also holds key identifying routine in the set (hash) of
stored routines used by statement.
sp_head:
Instead of two separate hashes sp_funs/m_spprocs representing sets of stored
routines used by this routine we use one hash - m_sroutines.
sp_instr_set_trigger_field:
Added support for subqueries in assignments to row accessors in triggers.
Removed definition of sp_add_sp_tables_to_table_list() and auxilary functions
since now we don't have separate stage on which we add tables used by routines
used by statement to table list for prelocking. We do it on the same stage as
we load those routines in SP cache. So all this functionality moved to
sp_cache_routines_and_add_tables() family of functions.
sql/sp_head.h:
sp_name:
Now this class also holds key identifying routine in the set (hash) of stored
routines used by statement.
sp_head:
Instead of two separate hashes sp_funs/m_spprocs representing sets of stored
routines used by this routine we use one hash - m_sroutines.
sp_instr_set_trigger_field:
Added support for subqueries in assignments to row accessors in triggers.
Removed declaration of sp_add_sp_tables_to_table_list() since now we don't have
separate stage on which we add tables used by routines used by statement to
table list for prelocking. We do it on the same stage as we load those routines
in SP cache.
sql/sql_base.cc:
open_tables():
- LEX::spfuns/spprocs hashes were replaced with one LEX::sroutines hash.
- Now instead of doing one pass through all routines used in statement for
caching them and then doing another pass for adding their tables to table
list, we do only one pass during which do both things. It is easy to do
since all routines in the set of routines used by statement are linked in
the list. This also allows us to calculate table list for prelocking more
precisely.
- Now triggers properly inform prelocking algorithm about tables they use.
sql/sql_lex.cc:
lex_start():
Replaced LEX::spfuns/spprocs with with one LEX::sroutines hash.
Added LEX::sroutines_list list linking all elements in this hash.
st_lex::st_lex():
Moved definition of LEX constructor to sql_lex.cc file to be able
use sp_sroutine_key declaration from sp.h in it.
sql/sql_lex.h:
LEX:
Replaced two separate hashes for stored routines used by statement with one.
Added list linking all elements in this hash to be able to iterate through all
elements and add new elements to this hash at the same time.
Moved constructor definition to sql_lex.cc.
sql/sql_parse.cc:
mysql_execute_command():
Replaced LEX::spfuns/spprocs with one LEX::sroutines hash.
sql/sql_trigger.cc:
Added missing GNU GPL notice.
Table_triggers_list::check_n_load()
Added initialization of sroutines_key which stores key representing
triggers of this table in the set (hash) of routines used by this statement.
sql/sql_trigger.h:
Added missing GNU GPL notice.
Table_triggers_list:
Added sroutines_key member to store key representing triggers of this
table in the set (hash) of routines used by this statement.
Declared sp_cache_routines_and_add_tables_for_triggers() as friend since
it needs access to sroutines_key and trigger bodies.
sql/sql_yacc.yy:
- Now we use sp_add_used_routine() instead of sp_add_to_hash() for adding
elements to the set of stored routines used in statement.
- Enabled support of subqueries as right sides in assignments to triggers' row
accessors.
sql/examples/ha_archive.h:
Fixed indention issues, modified scan_rows to being ha_rows, and fixed the diplsay show table status to mention that rows inside of archive are compressed.
