fe3dee0621 Fix for bug #20695: Charset introducer overrides charset definition for column.
- if there are two character set definitions in the column declaration,
    we replace the first one with the second one as we store both in the LEX->charset
    slot. Add a separate slot to the LEX structure to store underscore charset.
  - convert default values to the column charset of STRING, VARSTRING fields 
    if necessary as well.

d36f578130 Fix for BUG#20438: CREATE statements for views, stored routines and triggers
can be not replicable.

Now CREATE statements for writing in the binlog are created as follows:
  - the beginning of the statement is re-created;
  - the rest of the statement is copied from the original query.

The problem appears when there is a version-specific comment (produced by
mysqldump), started in the re-created part of the statement and closed in the
copied part -- there is closing comment-parenthesis, but there is no opening
one.

The proper fix could be to re-create original statement, but we can not
implement it in 5.0. So, for 5.0 the fix is just to cut closing
comment-parenthesis. This technique is also used for SHOW CREATE PROCEDURE
statement (so we are able to reuse existing code).

8995277acc A fix and a test case for Bug#19399 "res 'Lost Connection' when
dropping/creating tables".

The bug could lead to a crash when multi-delete statements were
prepared and used with temporary tables.

The bug was caused by lack of clean-up of multi-delete tables before
re-execution of a prepared statement. In a statement like
DELETE t1 FROM t1, t2 WHERE ... the first table list (t1) is
moved to lex->auxilliary_table_list and excluded from lex->query_tables
or select_lex->tables. Thus it was unaccessible to reinit_stmt_before_use
and not cleaned up before re-execution of a prepared statement. 


mysql-test/r/ps.result:
  Updated test results (Bug#19399)
mysql-test/t/ps.test:
  A test case for Bug#19399 "Stored Procedures 'Lost Connection' when 
  dropping/creating tables": test that multi-delete
  tables are cleaned up properly before re-execution.
sql/sql_lex.cc:
  Always initialize auxilliary_table_list when we initialize the lex:
  this way we don't have to check that lex->sql_command equals to
  SQLCOM_DELETE_MULTI whenever we need to access auxilliary_table_list.
  In particular, in reinit_stmt_before_use we can simply check that
  auxilliary_table_list is not NULL and clean it up if the check returns
  a true value.
sql/sql_prepare.cc:
  Move the one table clean-up functionality to a method of st_table_list.
  Clean up auxiliary_table_list if it's not empty.
sql/table.cc:
  Implement st_table_list::reinit_before_use().
sql/table.h:
  Declare st_table_list::reinit_before_use().

90cb4c03fd Bug#17203: "sql_no_cache sql_cache" in views created from prepared statement
The problem was that we restored SQL_CACHE, SQL_NO_CACHE flags in SELECT

the original value set by the user.

128c3942a8 Bug#17204 "second CALL to procedure crashes Server"
Bug#18282 "INFORMATION_SCHEMA.TABLES provides inconsistent info about invalid views"
This bug caused crashes or resulted in wrong data being returned
when one tried to obtain information from I_S tables about views
using stored functions.

It was caused by the fact that we were using LEX representing
statement which were doing select from I_S tables as active LEX
when contents of I_S table were built. So state of this LEX both
affected and was affected by open_tables() calls which happened
during this process. This resulted in wrong behavior and in
violations of some of invariants which caused crashes.

This fix tries to solve this problem by properly saving/resetting
and restoring part of LEX which affects and is affected by the
process of opening tables and views in get_all_tables() routine.
To simplify things we separated this part of LEX in a new class
and made LEX its descendant.

sql/sql_lex.cc:
  To simplify saving/resetting and restoring part of LEX which
  affects and is affected by the process of opening tables and
  views we moved it to new class Query_tables_list and made LEX
  descendant of this class. Also introduced two LEX methods 
  which can be used to save and reset or to restore this state.
sql/sql_lex.h:

  views we moved it to new class Query_tables_list and made LEX

sql/sql_show.cc:
  Now in get_all_tables() routine we properly save/reset and
  restore part of LEX (statement table list and information
  about routines used) which affects and is affected by the
  process of opening tables and views.
sql/sql_table.cc:
  Now we clean-up LEX after opening table (view) in two stages.
  In the first stage we call LEX::cleanup_after_one_table_open()
  to clean-up selects lists and derived tables state. In the
  second stage which happens after close_thread_tables() is
  invoked we call Query_tables_list::reset_query_tables_list(FALSE)
  to rollback changes in Query_tables_list.

375749b8af Fixed bug #14927.
A query with a group by and having clauses could return a wrong
result set if the having condition contained a constant conjunct 
evaluated to FALSE.
It happened because the pushdown condition for table with
grouping columns lost its constant conjuncts.
Pushdown conditions are always built by the function make_cond_for_table
that ignores constant conjuncts. This is apparently not correct when
constant false conjuncts are present.

ccc051cd40 fix for bug #12595 (ESCAPE must be exactly 1 character long)
ESCAPE has length of 1 if specified and sql_mode is NO_BACKSLASH_ESCAPES

  This is needed as fix for bug #12595 to distinguish between
  situation where ESCAPE was found and when not because internally
  we may pass a string an empty string and there is no other way
  to find out whether this is correct or not in case of 
  NO_BACKSLASH_ESCAPES mode, which allows only length of 1 if
  ESCAPE is part of the SQL statement.

d5303b8ab8 Fix for bug #12704 "Server crashes during trigger execution".
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.

c910050a76 Implement WL#2661 "Prepared Statements: Dynamic SQL in Stored Procedures".
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:

- current_arena to stmt_arena: the thread may have more than one
'current' arenas: one for runtime data, and one for the parsed 
tree of a statement. Only one of them is active at any moment.
- set_item_arena -> set_query_arena, because Item_arena was renamed to 
Query_arena a while ago
- set_n_backup_item_arena -> set_n_backup_active_arena;
the active arena is the arena thd->mem_root and thd->free_list
are currently pointing at.
- restore_backup_item_arena -> restore_active_arena (with the same
rationale)
- change_arena_if_needed -> activate_stmt_arena_if_needed; this

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

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.
sql/sql_class.h:
  - Commented old code.

    Needed to support an ugly trick to resolve inserted columns only in
    the first table.
  - Added Name_resolution_context::[first | last]_name_resolution_table.
  - Commented old code
sql/sql_lex.cc:
  - set select_lex.parent_lex correctly
  - set correct state of the current name resolution context

  - Improved comments
sql/sql_show.cc:

    implement name resolution for JOIN ... ON. A context is pushed
    for each new JOIN ... ON, and popped afterwards.
  - Added support for NATURAL/USING joins.
sql/table.cc:
  - Added new class Natural_join_column to hide the heterogeneous
    representation of column references for stored tables and for
    views.
  - Added a new list TABLE_LIST::next_name_resolution_table to
    support name resolution with NATURAL/USING joins. Also added
    other members to TABLE_LIST to support NATURAL/USING joins.
  - Added a generic iterator over the fields of table references

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.
mysql-test/r/sp-threads.result:

mysql-test/t/sp-threads.test:
  Added test for bug #11554 "Server crashes on statement indirectly using

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():

  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.

14b1f91ba4 Enable support of access to tables from triggers. Thus fix bug #8406 "Triggers
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.

936688feb5 A followup patch for Bug#7306 (limit in prepared statements):
don't evaluate subqueries during statement prepare, even if they
are not correlated.
With post-review fixes.


sql/mysql_priv.h:
  Add UNCACHEABLE_PREPARE to mark subqueries as non-constant in 
  mysql_stmt_prepare
sql/sql_lex.cc:
  Add a missing assert: noone can call unit::set_limit from 
  mysql_stmt_prepare.
sql/sql_lex.h:
  Comment fixed.
sql/sql_parse.cc:
  Mark new SELECT_LEXes as uncacheable if they created during 
  statement prepare.
sql/sql_prepare.cc:
  Switch off the uncacheable flag when prepare is done.

5188f031ae Patch two (the final one) for Bug#7306 "the server side preparedStatement
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.


mysql-test/include/ps_modify.inc:
  Fix existing tests: now LIMIT can contain placeholders.
mysql-test/include/ps_query.inc:
  Fix existing tests: now LIMIT can contain placeholders.
mysql-test/r/ps.result:
  Add basic test coverage for LIMIT ?, ? and fix test results.
mysql-test/r/ps_2myisam.result:
  Fix test results: now LIMIT can contain placeholders.
mysql-test/r/ps_3innodb.result:
  Fix test results: now LIMIT can contain placeholders.
mysql-test/r/ps_4heap.result:
  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.

78422442df Preparatory (and the most problematic) patch for Bug#7306
"the server side preparedStatement error for LIMIT placeholder",
which moves all uses of LIMIT clause from PREPARE to OPTIMIZE
and later steps.
After-review fixes.


mysql-test/r/group_min_max.result:
  Test results fixed for EXPLAINs when using GROUP_MIN_MAX access plan.
sql/item_subselect.cc:
  Move setting of the internal LIMIT used for IN/ALL/ANY/EXISTS 
  subqueries to one place: Item_exists_subselect::fix_length_and_dec().
  This implies that unit->select_limit_cnt is not set until the item is 
  fixed. This is OK, as now LIMIT values are not used until JOIN::optimize.
sql/mysql_priv.h:
  setup_tables no longer needs a special flag for the case when
  it's called from JOIN::reinit() (we don't need to call setup_tables
  between two executions of a correlated subquery).
sql/opt_range.cc:
  Fix a glitch in GROUP_MIN_MAX access plan: we should use table metadata,
  not field data, to evaluate max_used_key_length, which is then
  used for explain.
sql/sp.cc:
  - setup_tables signature changed.
sql/sql_base.cc:
  - setup_tables no longer needs a special mode for subqueries.
    Unused checks were removed.
sql/sql_delete.cc:
  - setup_tables signature changed
sql/sql_help.cc:
  - setup_tables signature changed
sql/sql_insert.cc:
  - setup_tables signature changed
sql/sql_lex.cc:
  Consolidate setting of internal LIMIT for IN/ALL/ANY/EXISTS subqeries
  in one place, and hence remove it from st_select_lex::test_limit().
sql/sql_lex.h:
  Cleanup signature of st_select_lex_unit::init_prepare_fake_select_lex().
sql/sql_load.cc:
  - setup_tables signature changed
sql/sql_olap.cc:
  - setup_tables signature changed
sql/sql_parse.cc:
  - st_select_lex_unit::set_limit() signature changed
sql/sql_select.cc:
  Move setting of JOIN::select_limit from JOIN::prepare
  to JOIN::optimize. At prepare, limit is unknown yet.
  Remove excessive cleanups from JOIN::reinit which were overwriting
  join->join_tab[i]->table->used_keys. This fixes the bug which was triggered
  by the change in item_subselect.cc.
sql/sql_union.cc:
  Class st_select_lex_unit was changed to avoid calls to 
   st_select_lex_unit::set_limit from places where it may be unknown.
  Now unit->select_limit_cnt is set at ::exec(). 
  st_select_lex_unit::init_prepare_fake_select_lex(): 
   - move out set_limit functionality
   - remove a few lines of dead code.
  st_select_lex_unit::prepare():
    - now we don't call set_limit at the time of prepare, so the value  
      of unit->select_limit_cnt may be unknown here. Use sl->select_limit
      instead.
  st_select_lex_unit::exec():
    - cleanup
    - call set_limit explicitly as it has been moved out of 
     init_prepare_fake_select_lex.
sql/sql_update.cc:
  - setup_tables signature changed

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.

3f24932124 WL#2130: Table locking for stored FUNCTIONs
Collect all tables and SPs refered by a statement, and open all tables
with an implicit LOCK TABLES. Do find things refered by triggers and views,
we open them first (and then repeat this until nothing new is found), before
doing the actual lock tables.


mysql-test/r/information_schema.result:
  Updated result for WL#2130.
mysql-test/r/lock.result:
  Updated result for WL#2130.
mysql-test/r/sp-error.result:
  Updated result for WL#2130.
mysql-test/r/sp.result:
  Updated result for WL#2130.
mysql-test/r/view.result:
  Updated result for WL#2130.
mysql-test/t/information_schema.test:
  Disabled one test case due to a bug involving LOCK TABLES,
  which shows up with WL#2130.
mysql-test/t/lock.test:
  New error message with WL#2130. This change is under debate and might change
  in the future, but will do for now.
mysql-test/t/sp-error.test:
  Updated for WL#2130. Some tests are voided when table access does work from
  functions.
mysql-test/t/sp.test:
  Updated for WL#2130.
mysql-test/t/view.test:
  Updated for WL#2130.
sql/item_func.cc:
  We now have to set net.no_send_ok for functions too, with WL#2130.
sql/share/errmsg.txt:
  Reused an error code since the old use was voided by WL#2130, but a new
  one was needed instead (similar, but more specific restriction).
sql/sp.cc:
  Fixed error handling and collection of used tables for WL#2130.
sql/sp.h:
  Fixed error handling and collection of used tables for WL#2130.
sql/sp_head.cc:
  Added support functions for collecting and merging hash tables and lists
  of used tables from SPs and substatements, for WL#2130.
sql/sp_head.h:
  Added support functions for collecting and merging hash tables and lists
  of used tables from SPs and substatements, for WL#2130.
sql/sql_base.cc:
  Changed the way table->query_id is tested and set during with locked tables
  in effect. This makes some SP test cases work with WL#2130, but has a side
  effect on some error cases with explicit LOCK TABLES. It's still debated if
  this is the correct way, so it might change.
sql/sql_class.h:
  Added flags for circumventing some interference between WL#2130 and mysql_make_view().
sql/sql_derived.cc:
  Added some missing initializations. (Potential bugs.)
sql/sql_lex.cc:
  Clear the new hash tables for WL#2130.
sql/sql_lex.h:
  Added hash tables for procedures and tables too (as for functions), for WL#2130.
sql/sql_parse.cc:
  WL#2130: Make table accesses from stored functions work by adding an implicit
  LOCK TABLES around (most) executed statements. To do this, we have to go through
  a loop where we collect all SPs and tables in mysql_execute_statement.
sql/sql_prepare.cc:
  Cache both functions and procedures for WL#2130.
sql/sql_show.cc:
  Added some missing initializations. (Potential bugs.)
sql/sql_view.cc:
  Shortcut mysql_make_view() if thd->shortcut_make_view is true during
  the pre-open phase for collecting tables in WL#2130. Otherwise, the
  similar mechanism here causes interference.
sql/sql_yacc.yy:
  For WL#2130, added caching of procedures and disallowed LOCK/UNLOCK TABLES in SPs.
