813fc4104e A fix and a test case for Bug#6513 "Test Suite: Values inserted by using
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.

fe24add743 WL#2486 - natural and using join according to SQL:2003
* Provide backwards compatibility extension to name resolution of
  coalesced columns. The patch allows such columns to be qualified
  with a table (and db) name, as it is in 4.1.
  Based on a patch from Monty.

* Adjusted tests accordingly to test both backwards compatible name
  resolution of qualified columns, and ANSI-style resolution of
  non-qualified columns.
  For this, each affected test has two versions - one with qualified
  columns, and one without.

sql/sql_base.cc:
  * Applied Monty's patch for backwards compatible name resolution
    of qualified columns. The idea is:
    - When a column is qualified, search for the column in all
      tables/views underlying each natural join. In this case
      natural joins are *not* considered leaves.
    - If a column is not qualified, then consider natural joins
      as leaves, thus directly search the result columns of
      natural joins.
  * Simplified 'find_field_in_tables()' - unified two similar
    loops into one.
sql/table.cc:
  - Removed method & members not needed after Monty's patch.

7517d7e112 Implementation of WL#2486 -
"Process NATURAL and USING joins according to SQL:2003".

* Some of the main problems fixed by the patch:
  - in "select *" queries the * expanded correctly according to
    ANSI for arbitrary natural/using joins
  - natural/using joins are correctly transformed into JOIN ... ON
    for any number/nesting of the joins.
  - column references are correctly resolved against natural joins
    of any nesting and combined with arbitrary other joins.

* This patch also contains a fix for name resolution of items
  inside the ON condition of JOIN ... ON - in this case items must
  be resolved only against the JOIN operands. To support such
  'local' name resolution, the patch introduces a stack of
  name resolution contexts used at parse time.

NOTICE:
- This patch is not complete in the sense that
  - there are 2 test cases that still do not pass -
    one in join.test, one in select.test. Both are marked
    with a comment "TODO: WL#2486".
  - it does not include a new test specific for the task

  - commented old code
sql/sql_base.cc:
  This file contains the core of the implementation of the processing
  of NATURAL/USING joins (WL#2486).
  - added many comments to old code
  - refactored the group of find_field_in_XXX procedures, and added a
    new procedure for natural joins. There is one find_field_in_XXX procedure
    per each type of table reference (stored table, merge view, or natural
    join); one meta-procedure that selects the correct one depeneding on the
    table reference; and one procedure that goes over a list of table
    referenes.
  - NATURAL/USING joins are processed through the procedures:
      mark_common_columns, store_natural_using_join_columns,
      store_top_level_join_columns, setup_natural_join_row_types.
    The entry point to processing NATURAL/USING joins is the
    procedure 'setup_natural_join_row_types'.
  - Replaced the specialized Field_iterator_XXX iterators with one
    generic iterator over the fields of a table reference.
  - Simplified 'insert_fields' and 'setup_conds' due to encapsulation of
    the processing of natural joins in a separate set of procedures.

    action times or/and trigger event types.
sql/lex.h:
  Added new symbol "TRIGGERS".
sql/mysql_priv.h:
  Added declaration of constant holding extension for trigger name (.TRN) files.
sql/mysqld.cc:

  open_unireg_entry():
    Now Table_triggers_list::check_n_load() has one more argument which
    controls whether we should prepare Table_triggers_list with fully functional

  Now triggers have database wide namespace. To support it we create special .TRN
  file with same name as trigger for each trigger. This file contains name of
  trigger's table so one does not need to specify it explicitly in DROP TRIGGER.
  Moreover DROP TRIGGER treats first part of trigger identifier as database name
  now. Updated mysql_create_or_drop_trigger() routine and
  Table_triggers_list::create_trigger()/drop_trigger()/check_n_load() methods
  accordingly. Added add_table_for_trigger() routine and
  Table_triggers_list::drop_all_triggers() method.
  
  Added Table_triggers_list::get_trigger_info() for obtaining trigger metadata.
sql/sql_trigger.h:
  Table_triggers_list:
    Use TRG_EVENT_MAX, TRG_ACTION_MAX instead of magic values.
    Added get_trigger_info() method for obtaining trigger's meta-data.
    Added drop_all_triggers() method which drops all triggers for table.
    Added declarations of trg_action_time_type_names/trg_event_type_names
    arrays which hold names of triggers action time types  and event types.
sql/sql_yacc.yy:
  Changed grammar for CREATE/DROP TRIGGER to support database wide trigger
  namespace. Added new SHOW TRIGGERS statement.

  enum enum_schema_tables:

11f9e513d7 Implementation of Monty's idea: Now we can open mysql.proc table for lookup
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.

    Removed unused function.

ac9f68b9fa Better approach for prelocking of tables for stored routines execution
and some SP-related cleanups.

- We don't have separate stage for calculation of list of tables
  to be prelocked and doing implicit LOCK/UNLOCK any more.
  Instead we calculate this list at open_tables() and do implicit
  LOCK in lock_tables() (and UNLOCK in close_thread_tables()).
  Also now we support cases when same table (with same alias) is
  used several times in the same query in SP.

- Cleaned up execution of SP. Moved all common code which handles
  LEX and does preparations before statement execution or complex
  expression evaluation to auxilary sp_lex_keeper class. Now 
  all statements in SP (and corresponding instructions) that
  evaluate expression which can contain subquery have their
  own LEX.


mysql-test/r/lock.result:
  Replaced wrong error code with the correct one after fixing bug in
  SP-locking.
mysql-test/r/mysqldump.result:
  Added dropping of view which is used in test to its beginning.
mysql-test/r/sp.result:
  Added tests for improved SP-locking.
  Temporarily disabled tests for SHOW PROCEDURE STATUS and alike
  (Until Monty will allow to open mysql.proc under LOCK TABLES without
  mentioning it in lock list).
  Replaced wrong results of test for bug #5240 with correct results after
  fixing bug in handling of cursors.
mysql-test/t/lock.test:
  Replaced wrong error code with the correct one after fixing bug in
  SP-locking.
mysql-test/t/mysqldump.test:
  Added dropping of view which is used in test to its beginning.
mysql-test/t/sp.test:
  Added tests for improved SP-locking.
  Temporarily disabled tests for SHOW PROCEDURE STATUS and alike
  (Until Monty will allow to open mysql.proc under LOCK TABLES without
  mentioning it in lock list).
  Removed test for bug #1654 since we already test exactly this function
  in one of SP-locking tests.
  Removed comment about cursor's wrong behavior in test for bug #5240
  after fixing bug which was its cause.
sql/item_func.cc:
  Removed comment which is no longer true.
sql/mysql_priv.h:
  Changed open_tables() signature.
  Now its 2nd parameter is in/out since it can add elements to table list.
sql/sp.cc:
  sp_find_procedure():
   Added one more parameter which enforces cache only lookup.
  
  sp_merge_hash():
   Now uses its return value to indicate that first of two hashes changed
   as result of merge.
  
  sp_cache_routines():
   This function caches all stored routines used in query now.
sql/sp.h:
  - sp_find_procedure() now has one more parameter which enforces cache only
    lookup.
  - sp_merge_hash() now uses its return value to indicate that first of two
    hashes changed as result of merge.
  - sp_cache_routines() caches all stored routines now. So it does not need
    third argument any more.
sql/sp_head.cc:
  sp_head::sp_head():
   Added initialization of new m_spfuns and m_spprocs members.
  
  sp_head::execute():
   Let us save/restore part of thread context which can be damaged by
   execution of instructions.
  sp_head::execute_function()/execute_procedure():
   Now it is responsibility of caller to close tables used in
   subqueries which are passed as routine parameters.
  
  sp_head::restore_lex():
   Let us accumulate information about routines used by this one
   in new m_spfuns, m_spprocs hashes.
  
  sp_lex_keeper::reset_lex_and_exec_core()
   Main method of new auxilary sp_lex_keeper class to which instructions 
   delegate responsibility for handling LEX and preparations before
   executing statement or calculating complex expression.
  
  Since all instructions which calculate complex expression or execute
  command now use sp_lex_keeper they have to implement
  sp_instr::exec_core() method. Most of instruction specific logic
  has moved from sp_instr::execute() to this new method.
  
  Removed sp_instr_set_user_var class which is no longer used, because
  nowdays we allow execution of statements in stored functions and
  triggers.
  
  sp_merge_table_list() became sp_head::merge_table_list() method. It
  also treats sp_head::m_sptabs as multi-set of tables now.
  
  sp_hash_to_table_list() became sp_head::add_used_tables_to_table_list().
  It takes into account that sp_head::m_sptabs is multi-set and allocates
  object into persistent arena of PS.
  
  Removed sp_merge_table_hash(), sp_open_and_lock_tables(),
  sp_unlock_tables(), sp_merge_routine_tables() methods since they are not
  used by new prelocking mechanism.
  
  Added sp_add_sp_tables_to_table_list() which serves for adding tables needed
  by routines used in query to the query table list for prelocking.
sql/sp_head.h:
  class sp_head:
  - Added m_spfuns, m_spprocs members for storing names of routines used
    by this routine.
  - Added add_used_tables_to_table_list() method which allows to add
    tables needed by this routine to query's table list.
  - Converted sp_merge_table_list() to sp_head::merge_table_list() method.
  - Changed semantics of THD::m_sptabs. Now it is multi-set which contains
    only tables which are used by this routine and not routines that are
    called from this one.
  
  Removed sp_merge_routine_tables(), sp_merge_table_hash(),
  sp_open_and_lock_tables(), sp_unlock_tables() calls since they are not
  used for our prelocking list calculation.
  
  Added auxilary sp_lex_keeper class to which instructions delegate
  responsibility for handling LEX and preparations before executing
  statement or calculating complex expression. This class uses
  new sp_instr::exec_core() method which is responsible for executing
  instruction's core function after all preparations were made.
  
  All instructions which hold and calculate complex expression now have
  their own LEX (by aggregating sp_lex_keeper instance). sp_instr_stmt
  now uses sp_lex_keeper too.
  
  Removed sp_instr_set_user_var class which is no longer used, because
  nowdays we allow execution of statements in stored functions and
  triggers.
sql/sp_rcontext.cc:
  Now sp_cursor holds pointer to sp_lex_keeper instead of LEX.
sql/sp_rcontext.h:
  Now sp_cursor holds pointer to sp_lex_keeper instead of LEX.
sql/sql_acl.cc:
  acl_init(), grant_init():
    Now we use simple_open_n_lock_tables() instead of explicit
    calls to open_tables() and mysql_lock_tables().
sql/sql_base.cc:
  Implemented support for execution of statements in "prelocked" mode.
  
  When we have statement which uses stored routines explicitly or
  implicitly (via views or triggers) we have to open and lock all tables
  for these routines at the same time as tables for the main statement.
  In fact we have to do implicit LOCK TABLES at the begining of such
  statement and implict UNLOCK TABLES at its end. We call such mode
  "prelocked".
  
  When open_tables() is called for the statement tables which are needed
  for execution of routines used by it are added to its tables list
  (this process also caches all routines used). Implicit use of routines
  is discovered when we open view or table with trigger and apropriate
  tables are added to the table list at this moment. Statement which has
  such extra tables in its list (well actually any that uses functions)
  is marked as requiring prelocked mode for its execution.
  
  When lock_tables() sees such statement it will issue implicit LOCK TABLES
  for this extended table list instead of doing usual locking, it will also
  set THD::prelocked_mode to indicate that we are in prelocked mode.
  
  When open_tables()/lock_tables() are called for statement of stored
  routine (substatement), they notice that we are running in prelocked mode
  and use one of prelocked tables from those that are not used by upper
  levels of execution.
  
  close_thread_tables() for substatement won't really close tables used
  but will mark them as free for reuse instead.
  
  Finally when close_thread_tables() is called for the main statement it
  really unlocks and closes all tables used.
  
  Everything will work even if one uses such statement under real LOCK
  TABLES (we are simply not doing implicit LOCK/UNLOCK in this case).
sql/sql_class.cc:
  Added initialization of THD::prelocked_mode member.
sql/sql_class.h:
  - Added prelocked_mode_type enum and THD::prelocked_mode member
    which are used for indication whenever "prelocked mode" is on 
    (i.e. that statement uses stored routines and is executed under
     implicit LOCK TABLES).
  - Removed THD::shortcut_make_view which is no longer needed.
    We use TABLE_LIST::prelocking_placeholder for the same purprose
    now.
sql/sql_handler.cc:
  Changed open_tables() invocation.
  Now its 2nd parameter is in/out since it can add elements to table list.
sql/sql_lex.cc:
  lex_start():
    Added initialization of LEX::query_tables_own_last.
    Unused LEX::sptabs member was removed.
  st_lex::unlink_first_table()/link_first_table_back():
    We should update LEX::query_tables_last properly if table list
    contains(ed) only one element.
sql/sql_lex.h:
  LEX:
  - Removed sptabs member since it is no longer used.
  - Added query_tables_own_last member, which if non-0 indicates that
    statement requires prelocking (implicit LOCK TABLES) for its execution
    and points to last own element in query table list. If it is zero
    then this query does not need prelocking.
  - Added requires_prelocking(), mark_as_requiring_prelocking(),
    first_not_own_table() inline methods to incapsulate and simplify
    usage of this new member.
sql/sql_parse.cc:
  dispatch_command():
    To properly leave prelocked mode when needed we should call
    close_thread_tables() even if there are no open tables.
  mysql_execute_command():
  - Removed part of function which were responsible for doing implicit
    LOCK TABLES before statement execution if statement used stored 
    routines (and doing UNLOCK TABLES at the end).
    Now we do all this in open_tables()/lock_tables()/close_thread_tables()
    instead.
  - It is also sensible to reset errors before execution of statement
    which uses routines.
  - SQLCOM_DO, SQLCOM_SET_OPTION, SQLCOM_CALL
    We should always try to open tables because even if statement has empty
    table list, it can call routines using tables, which should be preopened
    before statement execution.
  - SQLCOM_CALL
    We should not look up routine called in mysql.proc, since it should be
    already cached by this moment by open_tables() call.
  - SQLCOM_LOCK_TABLES
    it is better to use simple_open_n_lock_tables() since we want to avoid
    materialization of derived tables for this command.
sql/sql_prepare.cc:
  mysql_test_update():
    Changed open_tables() invocations. Now its 2nd parameter is in/out
    since it can add elements to table list.
  check_prepared_statement():
    Since now we cache all routines used by statement in open_tables() we 
    don't need to do it explicitly.
  mysql_stmt_prepare():
    Now we should call close_thread_tables() when THD::lex points to the
    LEX of statement which opened tables.
  reset_stmt_for_execute():
    Commented why we are resetting all tables in table list.
sql/sql_trigger.h:
  Table_triggers_list::process_triggers():
    We should surpress sending of ok packet when we are calling trigger's
    routine, since now we allow statements in them.
sql/sql_update.cc:
  Changed open_tables() invocations.
  Now its 2nd parameter is in/out since it can add elements to table list.
sql/sql_view.cc:
  mysql_make_view():
  - Removed handling of routines used in view. Instead we add tables which
    are needed for their execution to statement's table list in 
    open_tables().
  - Now we use TABLE_LIST::prelocking_placeholder instead of 
    THD::shortcut_make_view for indicating that view is opened
    only to discover which tables and routines it uses (this happens
    when we build extended table list for prelocking). Also now we try
    to avoid to modify main LEX in this case (except of its table list).
  - Corrected small error we added tables to the table list of the main
    LEX without updating its query_tables_last member properly.
sql/sql_yacc.yy:
  Now each expression which is used in SP statements and can contain
  subquery has its own LEX. This LEX is stored in corresponding sp_instr
  object and used along with Item tree for expression calculation.
  
  We don't need sp_instr_set_user_var() anymore since now we allow
  execution of statements in stored functions and triggers.
sql/table.h:
  Added TABLE_LIST::prelocking_placeholder member for distinguishing
  elements of table list which does not belong to the statement itself
  and added there only for prelocking (as they are to be used by routines
  called by this statement).
sql/tztime.cc:
  my_tz_init():
    Now we use more simplier simple_open_n_lock_tables() call instead of 
    open_tables()/lock_tables() pair.

2860a7723e Fixes for bug#8115 "Server Crash with prepared statement"
and bug#8849 "problem with insert statement with table alias's": 
make equality propagation work in stored procedures and prepared 
statements.
Equality propagation can change AND/OR structure of ON expressions,
so the fix is to provide each execution of PS/SP with it's own
copy of AND/OR tree. We have been doing that already for WHERE clauses,
now ON clauses are also copied.

  Call init_stmt_after_parse in restore_lex(), which is used to
  grab TABLE_LIST and SELECT_LEX list of a parsed substatement of
  stored procedure. This is a necessary post-init step which 
  must be done for any statement which can be executed many times.
sql/sql_prepare.cc:
  Implement init_stmt_after_parse() which prepares AND/OR
  structure of all ON expressions and WHERE clauses of a statement
  for copying.
sql/sql_select.cc:
  Implementation of equality propagation inspected with regard to 
  prepared statements and stored procedures. We now restore
  AND/OR structure of every ON expression in addition to AND/OR
  structure of WHERE clauses when reexecuting a PS/SP.
sql/table.h:
  Add declaration for TABLE::prep_on_expr.
