6b2f13098a Patch for WL#2894: Make stored routine variables work
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;

361977c0da Fix for bug #11555 "Stored procedures: current SP tables locking make
impossible view security".

We should not expose names of tables which are explicitly or implicitly (via
routine or trigger) used by view even if we find that they are missing.
So during building of list of prelocked tables for statement we track which
routines (and therefore tables for these routines) are used from views. We
mark elements of LEX::routines set which correspond to routines used in views
by setting Sroutine_hash_entry::belong_to_view member to point to TABLE_LIST
object for topmost view which uses routine. We propagate this mark to all
routines which are used by this routine and which we add to this set. We also
mark tables used by such routine which we add to the list of tables for
prelocking as belonging to this view.


mysql-test/r/sp-error.result:
  Added test for bug #11555 "Stored procedures: current SP tables locking make 
  impossible view security".
mysql-test/r/view.result:
  We should not expose tables which are expicitly/implicitly used in view in
  check table statement.
mysql-test/t/sp-error.test:
  Added test for bug #11555 "Stored procedures: current SP tables locking make 
  impossible view security".
mysql-test/t/view.test:
  Removed comment obsoleted by bugfix.
sql/sp.cc:
  We should not expose names of tables which are explicitly or implicitly
  (via routine or trigger) used by view even if we find that they are missing.
  So during building of list of prelocked tables for statement we track which
  routines (and therefore tables for these routines) are used from views. We

sql/sp.h:
  sp_cache_routines_and_add_tables_for_view()/for_triggers():
    To be able to determine correctly uppermost view which uses this view/table
    with trigger we have to pass pointer to TABLE_LIST object instead of pointer
    to view's LEX or to Table_triggers_list object.
sql/sp_head.cc:
  sp_head::add_used_tables_to_table_list():
    Added new argument which allows to mark tables which are added to table
    list for prelocking as belonging to view (this allows properly hide names
    of tables which are used in routines used by views).
sql/sp_head.h:
  sp_head::add_used_tables_to_table_list():
    Added new argument which allows to mark tables which are added to table
    list for prelocking as belonging to view (this allows properly hide names
    of tables which are used in routines used by views).
sql/sql_base.cc:
  open_tables():
    sp_cache_routines_and_add_tables_for_view()/for_triggers() now accept
    pointer to table list element as last argument, this allows them to determine
    correctly uppermost view which uses this view/table with trigger.
sql/sql_trigger.h:
  Table_triggers_list:
    sp_cache_routines_and_add_tables_for_triggers() now accept pointer to table
    list element as last argument, this allows to determine correctly uppermost
    view which uses this table with trigger.

7ff7977105 WL#1034 updated
- split into several files
- forbid parallel execution (before analyse is done how to make it possible)
  because the same sp_head instance cannot be executed in parallel
- added GPL headers
- changed EVENT_ACL to be per DB variable
- fixed minor problems


mysql-test/lib/init_db.sql:
  WL#1034 updated
  - add Event_priv to mysql.user (update test)
  - add updated mysql.event table struct
scripts/mysql_fix_privilege_tables.sql:
  WL#1034 updated
  add updated mysql.event structure
sql/Makefile.am:
  split event.cc into
  - event.cc (create/alter/drop)
  - event_executor.cc (main and worker threads)
  - event_timed.cc (class event_timed)
  - event_priv.h (some definitions used internally by the module)
sql/event.cc:
  - added GPL header
  - split into few files
  - fixed some issues after code review
  - now using SP routines for opening/traversing/closing tables
    (will be reverted)
sql/event.h:
  - add GPL header
  - remove two methods - inline them in sql_yacc.yy 
  - don't use absolute values for EVEX_ defines but the SP_ equivalents (have to move 100% to SP_
    defines and as later step to not transfer messages upwards in the stack but
    report them at the place they occur)
  - updated reference table definition
  - move default mem_root param from event.cc to the header
sql/mysqld.cc:
  WL#1034
  rename --event-executor to --event-scheduler
  executor sounds a bit scary :)
sql/set_var.cc:
  rename internal variable name from event_executor to event_scheduler
  (ppl won't be scarried anymore :)
sql/share/errmsg.txt:
  omit one %s - not needed
sql/sp_head.cc:
  disable this DBUG_PRINT for a bit. m_next_cached_sp is 0x0 and I get crash here...
sql/sp_head.h:
  remove m_old_cmq, a temporal variable is used in sql_yacc.yy (Serg's idea)
  to keep the previous state.
  $<ulong_val>$ =  ....
  
  YYTHD->client_capabilites != $<ulong_val>4;
  
  (the same is done also for class event_timed)
sql/sql_acl.cc:
  handle pre-5.1.4 table and give the user EVENT_ACL if he had CREATE_ACL
sql/sql_acl.h:
  fix the bitmask
sql/sql_parse.cc:
  - move from EVENT_ACL being global to EVENT_ACL being per DB like
    CREATE_PROC_ACL
  - lex->m_qname dropped, because not needed, fix code therefore
  - add comment that SHOW CREATE EVENT has to be implemented
sql/sql_yacc.yy:
  - use temporal variable of Bison to store a short lived value
  - fix indentation
  - inline 2 class event_timed methods in the parser
sql/tztime.h:
  be more expressive - it's already extern

f631b361b6 Table definition cache, part 2
The table opening process now works the following way:
- Create common TABLE_SHARE object
- Read the .frm file and unpack it into the TABLE_SHARE object
- Create a TABLE object based on the information in the TABLE_SHARE
  object and open a handler to the table object

Other noteworthy changes:
- In TABLE_SHARE the most common strings are now LEX_STRING's
- Better error message when table is not found
- Variable table_cache is now renamed 'table_open_cache'
- New variable 'table_definition_cache' that is the number of table defintions that will be cached
- strxnmov() calls are now fixed to avoid overflows
- strxnmov() will now always add one end \0 to result
- engine objects are now created with a TABLE_SHARE object instead of a TABLE object.
- After creating a field object one must call field->init(table) before using it

- For a busy system this change will give you:
 - Less memory usage for table object
 - Faster opening of tables (if it's has been in use or is in table definition cache)
 - Allow you to cache many table definitions objects
 - Faster drop of table

  Now table definitions are cached indepndent of open tables, which will speed up things when a table is in use at once from several places
  Views are not yet cached; For the moment we only cache if a table is a view or not.
  
  Faster implementation of find_temorary_table()
  Replace 'wait_for_refresh()' with the more general function 'wait_for_condition()'
  Drop table is slightly faster as we can use the table definition cache to know the type of the table

  Creation and destruct of TABLE_SHARE objects that are common for many TABLE objects
  
  The table opening process now works the following way:
  - Create common TABLE_SHARE object
  - Read the .frm file and unpack it into the TABLE_SHARE object
  - Create a TABLE object based on the information in the TABLE_SHARE
    object and open a handler to the table object
  
  open_table_def() is written in such a way that it should be trival to add parsing of the .frm files in new formats
sql/table.h:
  TABLE objects for the same database table now share a common TABLE_SHARE object
  In TABLE_SHARE the most common strings are now LEX_STRING's
sql/unireg.cc:

  Call field->init(table) for new created fields
sql/unireg.h:
  Added OPEN_VIEW
strings/strxnmov.c:
  Change strxnmov() to always add end \0
  This makes usage of strxnmov() safer as most of MySQL code assumes that strxnmov() will create a null terminated string

91ab707678 Background:
Since long, the compiled code of stored routines has been printed in the trace file
when starting mysqld with the "--debug" flag. (At creation time only, and only in
debug builds of course.) This has been helpful when debugging stored procedure
execution, but it's a bit awkward to use. Also, the printing of some of the
instructions is a bit terse, in particular for sp_instr_stmt where only the command
code was printed.

This improves the printout of several of the instructions, and adds the debugging-
only commands "show procedure code <name>" and "show function code <name>".
(In non-debug builds they are not available.)


sql/lex.h:
  New symbol for debug-only command (e.g. show procedure code).
sql/sp_head.cc:
  Fixed some minor debug-mode bugs in show_create_*().
  New method for debugging: sp_head::show_routine_code() - returns the "assembly code"
  for a stored routine as a result set.
  Improved the print() methods for many sp_instr* classes, particularly for
  sp_instr_stmt where the query string is printed as well (up to a max length, just
  to give a hint of which statement it is). Also print the names of variables and
  cursors in some instruction.
sql/sp_head.h:
  New debugging-only method in sp_head: show_routine_code().
  Added offset member to sp_instr_cpush for improved debug printing.
sql/sp_pcontext.cc:
  Moved find_pvar(uint i) method from sp_pcontext.h, and made it work for all
  frames, not just the first one. (For debugging purposes)
  Added a similar find_cursor(uint i, ...) method, for debugging.
sql/sp_pcontext.h:
  Moved find_pvar(uint i) method to sp_pcontext.cc.
  Added a similar find_cursor(uint i, ...) method, for debugging.
sql/sql_lex.h:
  Added new sql_command codes for debugging.
sql/sql_parse.cc:
  Added new commands for debugging, e.g. "show procedure code".
sql/sql_yacc.yy:
  Added new commands for debugging purposes:
  "show procedure code ..." and "show function code ...".
  These are only enabled in debug builds, otherwise they result in a syntax error.

898adb8cfc Fixed BUG#14498: Stored procedures: hang if undefined variable and exception
The problem was to continue at the right place in the code after the
  test expression in a flow control statement fails with an exception
  (internally, the test in sp_instr_jump_if_not), and the exception is
  caught by a continue handler. Execution must then be resumed after the

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

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.

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:
  - a new test for PREPARE/EXECUTE/DEALLOCATE in stored procedures.

276bd123b7 A fix and a test case for "Bug #12168 'DECLARE CONTINUE HANDLER FOR
NOT FOUND ...' in conditional handled incorrectly".

Whenever we remove an instruction during optimization, we need to
adjust instruction numbers (ip - instruction pointer) stored in all
instructions. In addition to that, sp_instr_hpush_jump, which 
corresponds to DECLARE CONTINUE HANDLER needs adjustment for m_handler,
which holds the number of instruction with the continue handler.
In the bug report, a wrong ip stored in m_handler was pointing at 
FETCH, which resulted in an error message and abnormal SP termination.
The fix is to just remove m_handler member from sp_instr_hpush_jump,
as it's always points to the instruction next to the DECLARE
statement itself (m_ip+1).

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.

0f64a49506 "Fix" for bug #11394 "Recursion in SP crash server" and bug #11600
"Stored procedures: crash with function calling itself".

Disallow recursive stored routines until we either make Item's and LEX
reentrant safe or will use spearate sp_head instances (and thus separate
LEX objects and Item trees) for each routine invocation.


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

  Disabled test cases containing recursive stored routines until we will

sql/share/errmsg.txt:
  Added error message saying that recursive stored routines are disallowed.
sql/sp_head.cc:
  sp_head::execute():
    Since many Item's and LEX members can't be used in reentrant fashion
    we have to disable recursion for stored routines. So let us track
    routine invocations using sp_head::m_is_invoked member and raise
    error when one attempts to call routine recursively.
sql/sp_head.h:
  sp_head:
    Added m_is_invoked member for tracking of routine invocations and
    preventing recursion.

91180cb8ab - implement inheritance of sp_instr: public Query_arena.
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.
sql/sql_prepare.cc:
  free_items() is now a member of Query_arena.

  free_items() now automatically sets free_list to zero.

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.

  Fixed error handling and collection of used tables for WL#2130.
sql/sp.h:

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.

c3da2d12f7 Fix for bug #5888 "Triggers with nonexistent columns cause packets
out of order". (final version)

Now instead of binding Item_trigger_field to TABLE objects during
trigger definition parsing at table open, we perform pass through
special list of all such objects in trigger. This allows easily check
all references to fields in old/new version of row in trigger during
execution of CREATE TRIGGER statement (this is more courtesy for users
since we can't check everything anyway).
We also report that such reference is bad by returning error from
Item_trigger_field::fix_fields() method (instead of setup_field())
This means that if trigger is broken we will bark during trigger
execution instead of trigger definition parsing at table open.
(i.e. now we allow to open tables with broken triggers).


mysql-test/r/trigger.result:
  Added test which attempts to create trigger for table referencing to
  field which does not exist in this table.
mysql-test/t/trigger.test:
  Added test which attempts to create trigger for table referencing to
  field which does not exist in this table.
sql/item.cc:
  Item_trigger_field::setup_field() now returns void. If any error
  will occur we will report it at fix_fields() stage.
sql/item.h:
  Item_trigger_field:
  - Added next_trg_field member for linking all such objects in trigger
    in one list.
  - Also setup_field() now returns void. If any error will occur we will
    report it at fix_fields() stage.
sql/mysql_priv.h:
  Added SQL_LIST::push_back() method which allows to add another SQL_LIST
  to the end of this SQL_LIST.
sql/sp_head.cc:
  sp_head::init()/reset_lex()/restore_lex():
   In order to fill global LEX::trg_table_fields (list of all 
   Item_trigger_field objects for trigger) we should init the same list
   in LEX of substatement before its parsing and merge it to global list
   after parsing.
sql/sp_head.h:
  sp_instr_trigger_field:
    Made trigger_field member public to be able to add it more easily to
    global list of all Item_trigger_field objects in trigger.
sql/sql_lex.cc:
  LEX::trg_table was removed.
sql/sql_lex.h:
  Now we are binding Item_trigger_field's to TABLE object by passing
  through specially constructed list of all such objects in this trigger
  instead of doing this during trigger definition parsing at table open.
  So we no longer need LEX::trg_table, we use LEX::trg_table_fields list
  instead.
sql/sql_parse.cc:
  mysql_execute_command():
    Since now we use trigger body for some checks in
    mysql_create_or_drop_trigger() we should destroy it only
    after calling this function.
sql/sql_trigger.cc:
  Now instead of binding Item_trigger_field to TABLE objects during
  trigger definition parsing at table open, we perform pass through
  special list of all such objects in trigger. This allows easily check
  all references to fields in old/new version of row in trigger during
  execution of CREATE TRIGGER statement (this is more courtesy for users
  since we can't check everything anyway).
  We also report that such reference is bad by returning error from
  Item_trigger_field::fix_fields() method (instead of setup_field())
  This means that if trigger is broken we will bark during trigger
  execution instead of trigger definition parsing at table open.
  (i.e. now we allow to open tables with broken triggers).
  
  Table_triggers_list::prepare_old_row_accessors() method was added to be
  able to reuse code creating Field objects referencing TABLE::record[1]
  buffer instead of TABLE::record[0].
sql/sql_trigger.h:
  Added Table_triggers_list::prepare_old_row_accessors() method to be
  able to reuse code creating Field objects referencing to TABLE::record[1]
  instead of record[0].
sql/sql_yacc.yy:
  Now instead of performing binding of Item_trigger_field objects
  to TABLE object during trigger definition parsing at table open,
  we perform this binding by passing through specially constructed
  list of all such items in trigger.
  We also check value returned from memory allocation functions.

52ac4935e7 WL#1218 "Triggers". Some very preliminary version of patch.
Mostly needed for Monty for him getting notion what needed for triggers 
from new .FRM format. 

Things to be done:
- Right placement of trigger's invocations
- Right handling of errors in triggers (including transaction rollback)
- Support for priviliges
- Right handling of DROP/RENAME table (hope that it will be handled automatically
  with merging of .TRG into .FRM file)
- Saving/restoring some information critical for trigger creation and replication
  with their definitions (e.g. sql_mode, creator, ...)
- Replication

Already has some known bugs so probably not for general review.

make characteristics (and SHOW) work right, we had to separate the old
definition blob in the mysql.proc table into separate fields for parameters,
return type, and body, and handle the characteristics (like SQL SECURITY)
separately... and then reassemble the CREATE string for parsing, of course.
This is rather ugly, mostly the parser bit. (Hopefully that will be better
with the new parser.)


Docs/sp-imp-spec.txt:
  Separated the definitions string of the procedure into different columns
  in the mysql.proc schema.
mysql-test/r/sp.result:
  New characteristics tests.
mysql-test/t/sp.test:
  New characteristics tests.
scripts/mysql_create_system_tables.sh:
  Separated the definitions string of the procedure into different columns
  in the mysql.proc schema.
scripts/mysql_fix_privilege_tables.sql:
  Separated the definitions string of the procedure into different columns
  in the mysql.proc schema.
sql/sp.cc:
  Separated the definitions string of the procedure into different columns.
  Rewrote much of the code related this (have a assemble the definition
  string from its different parts now) and the way characteristics are now
  handled, in order to make ALTER actually work.
sql/sp.h:
  Changed prototypes.
sql/sp_head.cc:
  Rewrote much of the code related to the new mysql.proc schema with separate
  definition fields (have to assemble the definition string from its different
  parts now) and the way characteristics are now handled, in order to make ALTER
  actually work.

  Separated the different parts of the definition strings: name, parameters,
  return type (for functions) and body.
sql/sql_yacc.yy:
  Separated the different parts of the definition strings: name, parameters,
  return type (for functions) and body.
  This is ugly and messy; hopefully there's a more elegant way to do this
  when the new parser is installed.

0521fb5444 Most of the groundwork for sprint task 729 (implement FUNCTIONs).
Expanded the mysql.proc table, reworked the find/create/drop functions
completely, added new functions for FUNCTIONs (lotta functions here :),
got rid of some unnecessary use of Item_strings while at it. Extended
the parser correspondingly, and fiddled around a bit to make SP FUNCTIONs
coexist with UDFs.
Can now CREATE and DROP FUNCTIONs. Invoking yet to come...

b1b6227485 Moved create/find/drop functions to a separate files (sp.cc,sp.h).
Fixed backpatching of forward jumps.
Implemented LOOP, WHILE, REPEAT (temporarily known as SPREPEAT).

Known bug: Expression evaluation still not quite ok (e.g. "x > 0"),
which is why IF and CASE is not yet implemented.

27de9ece81 Simplistic, experimental framework for Stored Procedures (SPs).
Implements creation and dropping of PROCEDUREs, IN, OUT, and INOUT parameters,
single-statement procedures, rudimentary multi-statement (begin-end) prodedures
(when the client can handle it), and local variables.
Missing most of the embedded SQL language, all attributes, FUNCTIONs, error handling,
reparses procedures at each call (no caching), etc, etc.
Certainly buggy too, but procedures can actually be created and called....

  Added SP files.
sql/item.cc:
  Added this*_item() methods for Item_splocal. (SP local variable)
sql/item.h:
  Added this*_item() methods for SPs in Item, and the new Item_splocal
  class (SP local variable).

  (Still rudimentary and lacking proper error handling...)
sql/sql_yacc.yy:
  Lots and lots of additions for SPs...
  (Still even more missing, and no error messages...)
