      Patch for WL#2894: Make stored routine variables work · 6b2f1309
      unknown authored
      according to the standard.
      
      The idea is to use Field-classes to implement stored routines
      variables. Also, we should provide facade to Item-hierarchy
      by Item_field class (it is necessary, since SRVs take part
      in expressions).
      
      The patch fixes the following bugs:
        - BUG#8702: Stored Procedures: No Error/Warning shown for inappropriate data 
          type matching; 
       
        - BUG#8768: Functions: For any unsigned data type, -ve values can be passed 
          and returned; 
       
        - BUG#8769: Functions: For Int datatypes, out of range values can be passed 
          and returned; 
       
        - BUG#9078: STORED PROCDURE: Decimal digits are not displayed when we use 
          DECIMAL datatype; 
       
        - BUG#9572: Stored procedures: variable type declarations ignored; 
       
        - BUG#12903: upper function does not work inside a function; 
       
        - BUG#13705: parameters to stored procedures are not verified; 
       
        - BUG#13808: ENUM type stored procedure parameter accepts non-enumerated
          data; 
       
        - BUG#13909: Varchar Stored Procedure Parameter always BINARY string (ignores 
          CHARACTER SET); 
       
        - BUG#14161: Stored procedure cannot retrieve bigint unsigned;
      
        - BUG#14188: BINARY variables have no 0x00 padding;
      
        - BUG#15148: Stored procedure variables accept non-scalar values;

      Fix for BUG#14920 Ordering aggregated result sets corrupts resultset. · e3f57552
      unknown authored
      The cause of the bug was the use of end_write_group instead of end_write
      in the case when ORDER BY required a temporary table, which didn't take
      into account the fact that loose index scan already computes the result
      of MIN/MAX aggregate functions (and performs grouping).
      
      The solution is to call end_write instead of end_write_group and to add
      the MIN/MAX functions to the list of regular functions so that their
      values are inserted into the temporary table.

      sql/sql_class.h:
        Added new member to TMP_TABLE_PARAM.
      sql/sql_select.cc:
        Enable result rows generated by loose index scan being written into
        a temporary table. The change is necessary because loose index
        scan already computes the result of GROUP BY and the MIN/MAX aggregate
        functions. This is realized by three changes:
        - create_tmp_table allocates space for aggregate functions in the
          list of regular functions,
        - use end_write instead of end_write group,
        - copy the pointers to the MIN/MAX aggregate functions to the list
          of regular functions TMP_TABLE_PARAM::items_to_copy.
      sql/sql_select.h:
        New parameter to create_tmp_table.

      if inner routine has more local variables than outer one, and

      THD::spcont was non-0 when we were parsing stored routine/trigger
      definition during execution of another stored routine. This confused
      methods of Item_splocal and forced them use wrong runtime context.
      Fix ensures that we always have THD::spcont equal to zero during
      routine/trigger body parsing. This also allows to avoid problems
      with errors which occur during parsing and SQL exception handlers.

      handling of savepoints in stored routines.

      Also now when we invoke stored function or trigger we create new savepoint

          member which is used to save/restore list of current savepoints on
          entering/leaving function.
      sql/sql_parse.cc:
        mysql_execute_command():

      Bug#14397 - OPTIMIZE TABLE with an open HANDLER causes a crash · 013b3d8a
      unknown authored
      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".
      
      
      include/my_pthread.h:
        Bug#14397 - OPTIMIZE TABLE with an open HANDLER causes a crash

      Bug#14397 - OPTIMIZE TABLE with an open HANDLER causes a crash · 7d183320
      unknown authored
      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".

      A fix and a test case for Bug#6513 "Test Suite: Values inserted by using · 813fc410
      unknown authored
      cursor is interpreted latin1 character and Bug#9819 "Cursors: Mysql Server
      Crash while fetching from table with 5 million records."
      A fix for a possible memory leak when fetching into an SP cursor
      in a long loop.
      The patch uses a common implementation of cursors in the binary protocol and 
      in stored procedures and implements materialized cursors.
      For implementation details, see comments in sql_cursor.cc
      
      
      include/my_sys.h:
        - declaration for multi_alloc_root
      libmysqld/Makefile.am:
        - drop protocol_cursor.cc, add sql_cursor.cc (replaces the old
        implementation of cursors with a new one)
      mysql-test/r/ctype_ujis.result:
        - test results fixed (a test case for Bug#6513)
      mysql-test/r/sp-big.result:
        - test results fixed (a test case for Bug#9819)
      mysql-test/t/ctype_ujis.test:
        Add a test case for Bug#6513 "Test Suite: Values inserted by using cursor is
         interpreted latin1 character"
      mysql-test/t/sp-big.test:
        Add a restricted test case for Bug#9819 "Cursors: Mysql Server Crash
        while fetching from table with 5 million records."
      mysys/my_alloc.c:
        - an implementation of multi_alloc_root; this is largely a copy-paste
          from mulalloc.c, but the function is small and there is no easy way
          to reuse the existing C function.
      sql/Makefile.am:
        - add sql_cursor.h, sql_cursor.cc (a new implementation of stored procedure
        cursors) and drop protocol_cursor.cc (the old one)
      sql/handler.cc:
        - now TABLE object has its mem_root always initialized.
          Adjust the implementation handler::ha_open
      sql/item_subselect.cc:
        - adjust to the changed declaration of st_select_lex_unit::prepare
      sql/protocol.h:
        - drop Protocol_cursor
      sql/sp_head.cc:
        - move juggling with Query_arena::free_list and Item::next to
          sp_eval_func_item, as this is needed in 3 places already.
      sql/sp_head.h:
        - declare a no-op implementation for cleanup_stmt in sp_instr_cpush.
          This method is needed for non-materializing cursors, which are yet not 
          used in stored procedures.
        - declaration for sp_eval_func_item
      sql/sp_rcontext.cc:
        - reimplement sp_cursor using the new implementation of server side cursors.
        - use sp_eval_func_item to assign values of SP variables from the
          row fetched from a cursor. This should fix a possible memory leak in 
          the old implementation of sp_cursor::fetch
      sql/sp_rcontext.h:
        - reimplement sp_cursor using the new implementation of server side cursors.
      sql/sql_class.cc:
        - disable the functionality that closes transient cursors at commit/rollback;
          transient cursors are not used in 5.0, instead we use materialized ones.
          To be enabled in a later version.
      sql/sql_class.h:
        - adjust to the rename Cursor -> Server_side_cursor
        - additional declarations of select_union used in materialized cursors
      sql/sql_derived.cc:
        - reuse bits of tmp table code in UNION, derived tables, and materialized
          cursors
        - cleanup comments
      sql/sql_lex.h:
        - declarations of auxiliary methods used by materialized cursors
        - a cleanup in st_select_lex_unit interface
      sql/sql_list.h:
        - add an array operator new[] to class Sql_alloc
      sql/sql_prepare.cc:
        - split the tight coupling of cursors and prepared statements to reuse 
          the same implementation in stored procedures
        - cleanups of error processing in Prepared_statement::{prepare,execute}
      sql/sql_select.cc:
        - move the implementation of sensitive (non-materializing) cursors to 
          sql_cursor.cc
        - make temporary tables self-contained: the table, its record and fields
          are allocated in TABLE::mem_root. This implementation is not clean
          and resets thd->mem_root several times because of the way create_tmp_table 
          works (many additional things are done inside it).
        - adjust to the changed declaration of st_select_lex_unit::prepare
      sql/sql_select.h:
        - move the declaration of sensitive (non-materializing) cursors to 
          sql_cursor.cc
      sql/sql_union.cc:
        - move pieces of st_select_unit::prepare to select_union and st_table
          methods to be able to reuse code in the implementation of materialized
          cursors
      sql/sql_view.cc:
        - adjust to the changed signature of st_select_lex_unit::prepare
      sql/table.cc:
        - implement auxiliary st_table methods for use with temporary tables
      sql/table.h:
        - add declarations for auxiliary methods of st_table used to work with 
         temporary tables
      tests/mysql_client_test.c:
        - if cursors are materialized, a parallel update of the table used
          in the cursor may go through: update the test.
      sql/sql_cursor.cc:
        New BitKeeper file ``sql/sql_cursor.cc'' -- implementation of server side
        cursors
      sql/sql_cursor.h:
        New BitKeeper file ``sql/sql_cursor.h'' - declarations for
        server side cursors.

      Implement WL#2661 "Prepared Statements: Dynamic SQL in Stored Procedures". · c910050a
      unknown authored
      The idea of the patch is to separate statement processing logic,
      such as parsing, validation of the parsed tree, execution and cleanup, 
      from global query processing logic, such as logging, resetting
      priorities of a thread, resetting stored procedure cache, resetting
      thread count of errors and warnings.
      This makes PREPARE and EXECUTE behave similarly to the rest of SQL
      statements and allows their use in stored procedures.
      This patch contains a change in behaviour:
      until recently for each SQL prepared statement command, 2 queries
      were written to the general log, e.g.
      [Query]   prepare stmt from @stmt_text;
      [Prepare] select * from t1 <-- contents of @stmt_text
      The chagne was necessary to prevent [Prepare] commands from being written
      to the general log when executing a stored procedure with Dynamic SQL.
      We should consider whether the old behavior is preferrable and probably
      restore it.
      This patch refixes Bug#7115, Bug#10975 (partially), Bug#10605 (various bugs
      in Dynamic SQL reported before it was disabled).
      
      
      mysql-test/r/not_embedded_server.result:
        Since we don't want to log Dynamic SQL in stored procedures,
        now the general log gets only one log entry per SQL statement.
      mysql-test/r/sp-error.result:
        - remove obsolete tests
        - a better error message for the case when a stored procedure that
        returns a result set is called from a function
      mysql-test/r/trigger.result:
        - a better error message for the case when a stored procedure that
        returns a result set is called from a trigger
      mysql-test/t/sp-error.test:
        - a better error message for the case when a stored procedure that
          returns a result set is called from a function.
        - move the comment to its place (end of file).
      mysql-test/t/trigger.test:
        - a better error message for the case when a stored procedure that
        returns a result set is called from a trigger
      sql/item_func.cc:
        - we need to pass sql_command explicitly to get_var_with_binlog, because
        when creating a query for SQL prepared statement thd->lex->sql_command
        points at SQLCOM_EXECUTE, which is not listed in the list of update
        queries.
      sql/log_event.h:
        - remove an extra copy of the previous sentence
      sql/mysql_priv.h:
        - fix declarations of sql_prepare.cc API
      sql/share/errmsg.txt:
        - a new error message, when one attempts to execute a prepared statement
        which is currently being executed (this can happen only in Dynamic SQL
        at the moment).
      sql/sp_head.cc:
        - extend sp_multi_results_command to return different flags for a
        command (and rename it)
        - add support for SQLCOM_PREPARE,SQLCOM_EXECUTE, SQLCOM_DEALLOCATE
          to sp_get_flags_for_command
        - replace multiple boolean sp_head members with uint m_flags
        - a fix for a crash when user variables are used in a stored procedure
          and binlog is on. A temporary fix for Bug#12637 "SP crashes the server 
         if it has update query with user var & binlog is enabled", which actually
         stands for stored functions: now instead of a crash we break
         replication if a user variable is used in a stored function which 
         is executed in prelocked mode.
      sql/sp_head.h:
        - replace multiple boolean flags of sp_head with uint m_flags;
        - add flag CONTAINS_DYNAMIC_SQL
        - use this flag to error if a stored procedure with Dynamic SQL is
          called from a function or trigger.
      sql/sql_class.cc:
        - Statement_map::insert should not delete a statement if it exists,
          now it's done externally to be able to handle the case when the
          statement being deleted is in use.
        - remove extra code (free_list is already reset in free_items)
      sql/sql_lex.cc:
        - add lex->stmt_prepare_mode; we can't rely on thd->command any more,
          because we don't reset it any more (Dynamic SQL requirement is that
          PS are as little intrusive as possible).
      sql/sql_lex.h:
        - declare bool LEX::stmt_prepare_mode
      sql/sql_parse.cc:
        - move prepared statement code to sql_prepare.cc
        - change declarations (refactored code)
        - better error message when one attempts to use Dynamic SQL or a 
          stored procedure that returns a result set in a function or trigger.
      sql/sql_prepare.cc:
        - major refactoring to ensure PREPARE/EXECUTE commands do not reset global THD
          state and allow their use in stored procedures.
        - add Prepared_statement::flags and use it to ensure no recursive execution
          of a prepared statement is possible
        - better comments
      sql/sql_yacc.yy:
        - enable PREPARE/EXECUTE/DEALLOCATE in stored procedures
        - produce an error message on attempt to use PREPARE/EXECUTE/DEALLOCATE
          in a stored function or trigger
      mysql-test/r/sp-dynamic.result:
        - sp-dynamic.test results
      mysql-test/t/sp-dynamic.test:
        - a new test for PREPARE/EXECUTE/DEALLOCATE in stored procedures.

      Save and clear run context before executing a stored function or trigger and restore it afterwards. · a914b527
      unknown authored
      This allows us to use statement replication with functions and triggers
      The following things are fixed with this patch:
      - NOW() and automatic timestamps takes the value from the main event for functions and triggers (which allows these to replicate with statement level logging)
      - No side effects for triggers or functions with auto-increment values(), last_insert_id(), rand() or found_rows()
      - Triggers can't return result sets
      
      Fixes bugs:
      #12480: NOW() is not constant in a trigger
      #12481: Using NOW() in a stored function breaks statement based replication
      #12482: Triggers has side effects with auto_increment values

      Fix for bug #10055 "Using stored function with information_schema causes empty · 39fda600

      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
          stack (or elsewhere) by their caller.
      sql/sql_class.h:
        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
          stack (or elsewhere) by their caller.
      sql/sql_handler.cc:
        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_prepare.cc:
        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_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
          a flush or hold namelock on them.

      A fix and a test case for Bug#10760 and complementary cleanups. · de6f5ae5
      unknown authored
      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.

      Implementation of Monty's idea: Now we can open mysql.proc table for lookup · 11f9e513
      unknown authored
      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.
      mysql-test/r/sp-threads.result:
        Added test for bug #11554 "Server crashes on statement indirectly using
        non-cached function".
      mysql-test/t/sp-error.test:
        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.
      mysql-test/t/sp-threads.test:
        Added test for bug #11554 "Server crashes on statement indirectly using
        non-cached function".
      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():
          Removed unused function.
      sql/sp.h:
        sp_function_exists():
          Removed unused function.
      sql/sql_base.cc:
        open_table():
          Added new parameter which allows to open table even if some-one has done a
          flush or holding namelock on it.
        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.
        Added THD::push_open_tables_state()/pop_open_tables_state() methods for
        saving/restoring this state.
      sql/sql_class.h:
        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.
        Added THD::push_open_tables_state()/pop_open_tables_state() methods for
        saving/restoring this state.
      sql/sql_lex.cc:
        Removed LEX::proc_table member which was not really used.
      sql/sql_lex.h:
        Removed LEX::proc_table member which was not really used.
      sql/sql_table.cc:
        open_table() has new parameter which allows to open table even if some-one
        has done a flush or holding namelock on it.
      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).

      - implement inheritance of sp_instr: public Query_arena. · 91180cb8
      unknown authored
        We need every instruction to have its own arena, because we want to
        track instruction's state (INITIALIZED_FOR_SP -> EXECUTED). Because of 
        `if' statements and other conditional instructions used in stored 
        procedures, not every instruction of a stored procedure gets executed 
        during the first (or even subsequent) execution of the procedure. 
        So it's better if we track the execution state of every instruction 
        independently.
        All instructions of a given procedure now also share sp_head's 
        mem_root, but keep their own free_list.
        This simplifies juggling with free Item lists in sp_head::execute.
      - free_items() moved to be a member of Query_arena. 
      - logic of 'backup_arena' debug member of Query_arena has been
        changed to support
        multi-backups. Until now, TRUE 'backup_arena' meant that there is
        exactly one active backup of the THD arena. Now it means simply that
        the arena is used for backup, so that we can't accidentally overwrite an 
        existing backup. This allows doing multiple backups, e.g. in
        sp_head::execute and Cursor::fetch, when THD arena is already backed up
        but we want to set yet another arena (usually the 'permanent' arena,
        to save permanent transformations/optimizations of a parsed tree).
      
      
      sql/sp_head.cc:
        - use Query_arena support in sp_head::execute() as now sp_instr inherites
          from it.
      sql/sp_head.h:
        - inherite sp_instr from Query_arena
      sql/sql_class.cc:
        - changed the principle of Query_arena::backup_arena; free_items is now
          a member of Query_arena.
      sql/sql_class.h:
        - changed the principle of Query_arena::backup_arena; free_items is now
          a member of Query_arena.

        free_items() is now a member of Query_arena.
      sql/sql_select.cc:
        free_items() now automatically sets free_list to zero.
