The problem was a code generation bug: cpop instructions were not generated when using ITERATE back to an outer block from a context with a declared cursor; this would make it push a new cursor without popping in-between, eventually overrunning the cursor stack with a crash as the result. Fixed the calculation of how many cursors to pop (in sp_pcontext.cc: diff_cursors()), and also corrected diff_cursors() and diff_handlers() to when doing a "leave"; don't include the last context we're leaving (we are then jumping to the appropriate pop instructions). mysql-test/r/sp.result: Updated result for new test case (BUG#16887) mysql-test/t/sp.test: New test case for BUG#16887 sql/sp_pcontext.cc: Added new parameter to sp_pcontext::diff_handlers() and diff_cursors(): They can either include (for iterate jumps) or exclude (for leave jumps) the outer context. Fixed bug in diff_cursors(); it was just plain wrong and would return zero in some situations when it shouldn't. sql/sp_pcontext.h: Added new parameter to sp_pcontext::diff_handlers() and diff_cursors(): They can either include (for iterate jumps) or exclude (for leave jumps) the outer context. sql/sql_yacc.yy: Added parameter to diff_handlers/diff_cursors depending on if it's an iterate or leave jump. For "leave", we don't have to include the last context we're leaving since we will jump to the appropriate pop instructions.

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;

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. (I.e. they don't exist)

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.)

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...)
