after execution of a substatement. (Which means these must always be properly
initialized for all queries.)

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...

sql/sp.cc:
Major rehack to accomodate FUNCTIONs, and to make it easier to add
future in-memory cache of prepared SPs.
sql/sp.h:
Major rehack to accomodate FUNCTIONs, and to make it easier to add
future in-memory cache of prepared SPs.
sql/sp_head.cc:
Now creates FUNCTIONs too. (And got rid of some unnecessary Item_string use.)
sql/sp_head.h:
Now creates FUNCTIONs too. (And got rid of some unnecessary Item_string use.)
sql/sql_lex.h:
New stored FUNCTION commands.
sql/sql_parse.cc:
Added FUNCTION support ("drop" merged with the old UDF code), and made some
additional changes for better error handling (following the sp.cc rehacking).
sql/sql_yacc.yy:
Some former UDF specific symbols renamed.
Added CREATE FUNCTION parsing.
DROP FUNCTION had to be partly merged with the old UDF code, because of the similar
syntax.
RETURN statement added, but still a no-op.
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...
sql/sp.cc:
Added DBUG statements.
sql/sp_head.cc:
Added DBUG statements.
sql/sql_parse.cc:
Changed returns into DBUG_RETURNs in mysql_execute_command().
sql/sql_yacc.yy:
Small optimization: Don't generate sp_instr_stmt instructions for empty
SET_OPTIONs. (Which happened if there were only local variables in the SET
statement.)
sql/sp_head.cc:
Fixed crash bug when certain procedures are called from the top level.
Attempted to support global user vars as OUT/INOUT parameters too, but
unfortunately we can't quite manage that yet.
include/mysqld_error.h:
Added error codes for SPs
sql/mysql_priv.h:
Changed return value of mysql_execute_command() from void to int; need to be able
to detect if executions of substatements in SPs failed.

sql/sp_head.cc:
Moved net.no_send_ok fiddling to sql_parse.cc.
Check if mysql_execute_command() failed.
sql/sql_parse.cc:
Changed return value of mysql_execute_command() from void to int; need to be able
to detect if executions of substatements in SPs failed. Fixed all returns
accordingly.
Added error checks for SQLCOM_CREATE_PROCEDURE, CALL, ALTER_PROCEDURE, and
DROP_PROCEDURE.
sql/sp_head.cc:
Renamed m_mylex into m_call_lex.
Fixed some data collection.
sql/sp_head.h:
Renamed m_mylex into m_call_lex.
Put called procedures and used tables in class member vars (for now at least).
sql/sp_head.cc:
Init. the simple_case flag.
sql/sp_head.h:
New flag for (simple)case parsing.
sql/sp_pcontext.cc:
Removed push_gen_label method (not needed any more).
sql/sp_pcontext.h:
Removed push_gen_label method (not needed any more).
Fixed bug in pop().
sql/sql_yacc.yy:
Added CASE parsing.
Implemented IF-THEN-ELSE.
sql/sp_head.cc:
Reimplemented the broken backpatching, so it works for nested constructions and
IF-THEN-ELSE too.
sql/sp_head.h:
Reimplemented the broken backpatching, so it works for nested constructions and
IF-THEN-ELSE too.
sql/sp_pcontext.cc:
Return the value from push-methods, for convenience.
sql/sp_pcontext.h:
Return the value from push-methods, for convenience.
sql/sql_yacc.yy:
Implemented IF-THEN-ELSE.
Corrected for the new backpatch method.
Fixed eval bug; now conditions with local variables work in WHILE et al.
Made mysql_install_db.sh create proc table.
scripts/mysql_install_db.sh:
Added creation of the mysql.proc table.
Note: The table format will change later, right now it's rather minimalistic,
just so things can be tested (and the database can easily be recreated when
I break it :-/ ).
sql/item.h:
Removed unused method.
sql/sp_head.cc:
Added collection of called procedures in a list.
Fixed eval bug; now conditions with local variables work in WHILE et al.
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.
sql/Makefile.am:
Added new sp.h/sp.cc file.
sql/item.h:
New deferred result_type() method in Item_splocal.
sql/lex.h:
Temporary fix until REPEAT conflict is solved. Use SPREPEAT for now.
sql/sp_head.cc:
Moved create/find/drop functions to sp.cc.
Fixed the backpatch stuff.
(Also removed some dead code and updated comments.)
sql/sp_head.h:
Moved create/find/drop declarations to sp.h.
Fixed the backpatch stuff.
sql/sp_pcontext.h:
New method: last_label().
sql/sql_parse.cc:
Include sp.h.
sql/sql_yacc.yy:
Fixed backpatching of forward jumps.
Implemented LOOP, WHILE, and REPEAT. (Note: SPREPEAT for now.)
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.
for better jump support. Some flow control support added too (but not
complete).
sql/lex.h:
Added more keywords for embedded SQL.
sql/sp_head.cc:
Fixed bugs in the parameter evaluation.
Modified execute() for better jump support.
Added jump instruction and backpatch support.
sql/sp_head.h:
Fixed bugs in the parameter evaluation.
Modified execute() for better jump support.

sql/sp_pcontext.cc:
Added label support.
sql/sp_pcontext.h:
Added label support.
sql/sql_yacc.yy:
Outlined flow control constructs (parses, but nothing generated yet).
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....
sql/Makefile.am:
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).
sql/lex.h:
Added new symbols for SPs. (Note: SPSET is temporary and will go away later.)
sql/sql_class.cc:
Initialize SP runtime context in THD.
sql/sql_class.h:
Add SP runtime context to THD.
sql/sql_lex.cc:
Init. buf pointer to beginning of command (needed by SPs).
Also initialize SP head and parse time context.
sql/sql_lex.h:
New SQLCOM_ tags for SPs, and added pointer to beginning of command pointer and
SP head and parse-time context to LEX.
sql/sql_parse.cc:
Added SQLCOM_CREATE_PROCEDURE, _CALL, _ALTER_PROCEDURE and _DROP_PROCEDURE cases.
(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...)
