Had to add a cahing mechanism which is in parts an ugly kludge, but it will be reworked once the real SP caching is implemented. mysql-test/r/sp.result: New function tests. mysql-test/t/sp.test: New function tests. sql/sp.cc: Big rehack of mysql.proc table usage strategy and adding a function cache mechanism, since we need to read used functions from the db before doing anything else when executing a query. (This cache is temporary and will probably be replaced by the real thing later.) sql/sp.h: New (temporary) FUNCTION caching functions. sql/sp_head.cc: Fixed some bugs in the function and procedure execution. Disabled some data collections that's not used at the moment. sql/sp_head.h: Fixed some bugs in the function and procedure execution. Disabled some data collections that's not used at the moment. sql/sql_class.h: Added SP function cache list to thd. sql/sql_lex.cc: Added SP function name list to lex. sql/sql_lex.h: Added SP function name list to lex. sql/sql_parse.cc: Read used FUNCTIONs from db and cache them in thd before doing anything else in a query execution. (This is necessary since we can't open mysql.proc during query execution.) sql/sql_yacc.yy: Collect used function names in lex.

various known problems, but good enough for a checkpoint commit. mysql-test/r/sp.result: New tests for invoking simple FUNCTIONs. mysql-test/t/sp.test: New tests for invoking simple FUNCTIONs. sql/item_func.cc: New Item_func_sp for stored FUNCTIONs. sql/item_func.h: New Item_func_sp for stored FUNCTIONs. sql/sp.cc: Close mysql.proc table earlier so recursive find_function calls work. Added temporary sp_function_exists() function for checking without parsing. sql/sp.h: Added temporary sp_function_exists() function for checking without parsing. sql/sp_head.cc: New code for executing a FUNCTION. (And reworked some of the old code in the process.) sql/sp_head.h: New code for executing a FUNCTION. sql/sp_rcontext.h: Added result slot for FUNCTIONs. sql/sql_lex.cc: Added check for stored FUNCTION, analogous to UDFs. sql/sql_parse.cc: sp_head::execute was renamed into execute_procedure. sql/sql_yacc.yy: Added parsing of stored FUNCTION invocation and code generation for RETURN statement.

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... Docs/sp-implemented.txt: Updated with info about CASCADE/RESTICT and METHOD, and some answers to questions. include/mysqld_error.h: New error message for misuse of RETURN. mysql-test/install_test_db.sh: Added enum field to mysql.proc to distinguish between FUNCTION and PROCEDURE. mysql-test/r/sp.result: New test for creating and dropping FUNCTIONS. mysql-test/t/sp.test: New test for creating and dropping FUNCTIONS. scripts/mysql_install_db.sh: Added enum field to mysql.proc to distinguish between FUNCTION and PROCEDURE. sql/lex.h: De-UDFed some symbol names, as they are now used for SPs as well. Added RETURN_SYM. sql/share/czech/errmsg.txt: New error message for misuse of RETURN. sql/share/danish/errmsg.txt: New error message for misuse of RETURN. sql/share/dutch/errmsg.txt: New error message for misuse of RETURN. sql/share/english/errmsg.txt: New error message for misuse of RETURN. sql/share/estonian/errmsg.txt: New error message for misuse of RETURN. sql/share/french/errmsg.txt: New error message for misuse of RETURN. sql/share/german/errmsg.txt: New error message for misuse of RETURN. sql/share/greek/errmsg.txt: New error message for misuse of RETURN. sql/share/hungarian/errmsg.txt: New error message for misuse of RETURN. sql/share/italian/errmsg.txt: New error message for misuse of RETURN. sql/share/japanese/errmsg.txt: New error message for misuse of RETURN. sql/share/korean/errmsg.txt: New error message for misuse of RETURN. sql/share/norwegian-ny/errmsg.txt: New error message for misuse of RETURN. sql/share/norwegian/errmsg.txt: New error message for misuse of RETURN. sql/share/polish/errmsg.txt: New error message for misuse of RETURN. sql/share/portuguese/errmsg.txt: New error message for misuse of RETURN. sql/share/romanian/errmsg.txt: New error message for misuse of RETURN. sql/share/russian/errmsg.txt: New error message for misuse of RETURN. sql/share/serbian/errmsg.txt: New error message for misuse of RETURN. sql/share/slovak/errmsg.txt: New error message for misuse of RETURN. sql/share/spanish/errmsg.txt: New error message for misuse of RETURN. sql/share/swedish/errmsg.txt: New error message for misuse of RETURN. sql/share/ukrainian/errmsg.txt: New error message for misuse of RETURN. 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.

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 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.)

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. Added jump instruction and backpatch 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...)
