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 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...)
