      Fixed bug #320.
      Some new tests and cosmetic changes.
      Another strcasecmp() replaced.
      
      
      mysql-test/r/sp.result:
        Moved SP tests from subselect and added some more.
      mysql-test/r/subselect.result:
        Moved SP tests to sp.test.
      mysql-test/t/sp.test:
        Moved SP tests from subselect and added some more.
      mysql-test/t/subselect.test:

        Minor comment fix.
      sql/sql_derived.cc:
        Don't set org_table_list->derived to 1 when debugging, as this breaks certain
        subselect args to SPs.

      Made FUNCTIONs work in insert and select queries, as well as nested function invocations. · 8a9422bd
      unknown authored
      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.

      Expanded the mysql.proc table, reworked the find/create/drop functions

        Added CREATE FUNCTION parsing.
        DROP FUNCTION had to be partly merged with the old UDF code, because of the similar

        RETURN statement added, but still a no-op.

      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 :-/ ).

      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.)

        Moved create/find/drop declarations to sp.h.
        Fixed the backpatch stuff.

      Simplistic, experimental framework for Stored Procedures (SPs). · 27de9ece
      unknown authored
      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...)
