61a68ed6fa Clumsy but working fix for bug #11973 "SELECT .. INTO var_name; in trigger
cause crash on update".

Let us update "thd" pointer in LEX, all its units and in LEX::result before
executing statement in trigger body, since triggers are associated with TABLE
object and because of this can be used in different threads.


mysql-test/r/trigger.result:
  Added test case for bug #11973 "SELECT .. INTO var_name; in trigger cause
  crash on update".
mysql-test/t/trigger.test:
  Added test case for bug #11973 "SELECT .. INTO var_name; in trigger cause
  crash on update".
sql/item_subselect.cc:
  subselect_engine:
    Moved implementation of set_thd() method to item_subselect.cc,
    since now it also sets "thd" for subselect_engine::result.
sql/item_subselect.h:
  subselect_engine:
    Moved implementation of set_thd() method to item_subselect.cc,
    since now it also sets "thd" for subselect_engine::result.
sql/sql_class.h:
  select_result:
    Added set_thd() method for updating select_result::thd value (we need this
    in cases when statement to which this select_result belongs will be used
    in different threads, as it happens for statements in trigger body).
  multi_delete/multi_update:
    Got rid of redundant "thd" member (we already have it in select_result).
sql/sql_delete.cc:
  multi_delete:
    Got rid of redundant "thd" member (we already have it in select_result).
sql/sql_lex.h:
  st_select_lex_unit:
    Added set_thd() method for updating st_select_lex_unit::thd value
    (we need this in cases when statement to which this unit belongs will
     be used in different threads, as it happens for statements in trigger body).
    We don't update thd of select_result pointed by st_select_lex_unit::result
    in this method, since it is either have too short lifetime (i.e. created for
    each execution) or is accessible via Item_subquery or LEX::result and thus
    already taken care of.
sql/sql_parse.cc:
  multi_delete:
    Got rid of redundant "thd" member (we already have it in select_result).
sql/sql_prepare.cc:
  reinit_stmt_before_use():
    We have to update "thd" pointer in LEX, all its units and in LEX::result,
    since statements which belong to trigger body are associated with TABLE
    object and because of this can be used in different threads.
sql/sql_update.cc:
  multi_update:
    Got rid of redundant "thd" member (we already have it in select_result).

502e97f875 Fix for BUG#12228: SP cache code:
* Cleanup SP Cache code, now SP Cache only deletes sp_head objects in 
  sp_cache_flush_obsolete() invalidates all pointers to routines in the cache.
* Use new SP Cache use contract in the code.

There is no test case because it doesn't seem to be possible to cause thread races to end
the same way they end in heavy-load test. This patch removes the crash in heavy test.

  Fix for BUG#12228: When a routine is deleted/modified, invalidate all cached SPs in all

sql/sp_cache.cc:
  Fix for BUG#12228:
  * Move class sp_cache to here from sp_cache.h, document the functions.
  * sp_cache_insert, sp_cache_remove, sp_cache_invalidate and sp_cache_lookup must not delete
    sp_head* objects as they may be called during SP execution when sp_head objects are used.
  * Added sp_cache_flush_obsolete() function that may delete sp_head objects.
  * Removed sp_cache_remove as there is no need for it now - when we change one SP we should
    invalidate all other SPs, because sp_lex_keeper::{prelocking_tables, 
    query_tables_own_last} from one SP depend on content of another SP (used in 
    sp_lex_keeper::m_lex).

39fda60043 Fix for bug #10055 "Using stored function with information_schema causes empty
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

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():

    Replaced push_open_tables_state/pop_open_tables_state() methods which

    Added 'flags' argument to be able open tables even if some has done
    a flush or hold namelock on them.
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

de6f5ae5ab A fix and a test case for Bug#10760 and complementary cleanups.
The idea of the patch
is that every cursor gets its own lock id for table level locking.
Thus cursors are protected from updates performed within the same 
connection. Additionally a list of transient (must be closed at
commit) cursors is maintained and all transient cursors are closed
when necessary. Lastly, this patch adds support for deadlock
timeouts to TLL locking when using cursors.
+ post-review fixes.


include/thr_lock.h:
  - add a notion of lock owner to table level locking. When using
    cursors, lock owner can not be identified by a thread id any more, 
    as we must protect cursors from updates issued within the same 
    connection (thread). So, each cursor has its own lock identifier to 
    use with table level locking.
  - extend return values of thr_lock and thr_multi_lock with
    THR_LOCK_TIMEOUT and THR_LOCK_DEADLOCK, since these conditions
    are now possible (see comments to thr_lock.c)
mysys/thr_lock.c:
  Better support for cursors:
  - use THR_LOCK_OWNER * as lock identifier, not pthread_t.
  - check and return an error for a trivial deadlock case, when an
    update statement is issued to a table locked by a cursor which has 
    been previously opened in the same connection.
  - add support for locking timeouts: with use of cursors, trivial 
    deadlocks can occur. For now the only remedy is the lock wait timeout,
    which is initialized from a new global variable 'table_lock_wait_timeout'
    Example of a deadlock (assuming the storage engine does not downgrade 
    locks):
    con1: open cursor for select * from t1;
    con2: open cursor for select * from t2;
    con1: update t2 set id=id*2;  -- blocked
    con2: update t1 set id=id*2;  -- deadlock
    Lock timeouts are active only if a connection is using cursors.
  - the check in the wait_for_lock loop has been changed from
    data->cond != cond to data->cond != 0. data->cond is zeroed
    in every place it's changed.

    specific state.
sql/handler.h:
  - extend struct handlerton with flags, add handlerton *ht to every
    handler instance.
sql/lock.cc:
  - extend mysql_lock_tables to send error to the client if 
    thr_multi_lock returns a timeout or a deadlock error.
sql/mysqld.cc:
  - add server option --table_lock_wait_timeout (in seconds)
sql/set_var.cc:
  - add new global variable 'table_lock_wait_timeout' to specify
  a wait timeout for table-level locks of MySQL (in seconds). The default
  timeout is 50 seconds. The timeout is active only if the connection
  has open cursors.
sql/sql_class.cc:
  - implement Statement_map::close_transient_cursors
  - safety suggests that we need an assert ensuring 
   llock_info->n_cursors is functioning properly, adjust destruction of
   the Statement_map to allow such assert in THD::~THD
sql/sql_class.h:
  - add support for Cursors registry to Statement map.
sql/sql_prepare.cc:
  - maintain a list of cursors that must be closed at commit/rollback.
sql/sql_select.cc:
  - extend class Cursor to support specific at-COMMIT/ROLLBACK behavior.
  If a cursor uses tables of a storage engine that 
  invalidates all open tables at COMMIT/ROLLBACK, it must be closed
  before COMMIT/ROLLBACK is executed.

3a31f7b91f Simple fixes during review of new code
include/my_global.h:
  Added floatget() to read unaligned flaot
mysql-test/r/select.result:
  Added test for found_rows()
mysql-test/t/select.test:
  Added test for found_rows()
sql/des_key_file.cc:
  Moved initalization of LOCK_des_key_file to mysqld to make simpler code and avoid theoretical race condition
sql/field_conv.cc:
  Added optimizzed varsion of do_cut_string (for simple character sets)
sql/item_func.cc:
  Simplify code (and ensure DBUG_ENTER is excuted before main code)
sql/item_strfunc.cc:
  Safe calculation of max_length
  This was needed as max_length can now be 1<<32-1 (after konstantins recent patch to fix BLOB_LENGTH)
  Remove init_des_key_file() as this is not initialized in mysqld.cc
sql/item_timefunc.cc:
  Safe calculation of max_length
  This was needed as max_length can now be 1<<32-1 (after konstantins recent patch to fix BLOB_LENGTH)
sql/log_event.cc:
  Simplify code
sql/mysql_priv.h:
  Moved initalization of LOCK_des_key_file to mysqld to make simpler code and avoid theoretical race condition
sql/mysqld.cc:
  Moved initalization of LOCK_des_key_file to mysqld to make simpler code and avoid theoretical race condition
  Revert wrong patch of calling close_connection() in first close_connections() loop. (Bug #7403)
  Instead we now print a warning for closed connections only if mysqld is sarted with --warnings
  Added comments to make the close_connections() logic clearer
sql/sql_prepare.cc:
  Use floatget() and doubleget() to protect against unaligned data
sql/sql_select.cc:
  Fixed some cases unlikely cases where found_rows() would return wrong for queries that would return 0 or 1 rows

10b76d41a4 Jim's fix for the #10443.
Fix handling of floats and doubles when using prepared statements             
API in the embedded server. 


sql/sql_prepare.cc:
  Jim's fix for the #10443.
  
  Within the embedded server, there's no need to use float4get()              
  and float8get() for setting parameters, since they are never                
  stored.

fd9f67f8d2 Implement MarkM optimization request to avoid redundnat packet exchange
in cursors.


libmysql/libmysql.c:
  - reset_stmt_handle(): don't reset the server side just because we have 
    an open cursor: the server will close the cursor automatically if 
    needed
sql/sql_prepare.cc:
  - implement Prepared_statement::close_cursor,
  - implicitly close an open cursor in mysql_stmt_execute instead of 
    issuing an error (to reduce the need to explicitly close cursors
    and save network bandwidth).
  - cleanup
sql/sql_select.cc:
  Remove a destructor: cursor destruction can not be done by simply
  calling a destructor, because of cross-references between cursor
  and statement memory.
sql/sql_select.h:
  - add an empty Cursor destructor
tests/mysql_client_test.c:
  - remove a test for dropped functionality

ece17ba3cf - a fix for Bug#11458 "Prepared statement with subselects return random
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.

    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:

  prepare is done (backport from 5.0)
