Auto-merge from mysql-trunk-bugfixing.
****** This patch fixes the following bugs: - Bug#5889: Exit handler for a warning doesn't hide the warning in trigger - Bug#9857: Stored procedures: handler for sqlwarning ignored - Bug#23032: Handlers declared in a SP do not handle warnings generated in sub-SP - Bug#36185: Incorrect precedence for warning and exception handlers The problem was in the way warnings/errors during stored routine execution were handled. Prior to this patch the logic was as follows: - when a warning/an error happens: if we're executing a stored routine, and there is a handler for that warning/error, remember the handler, ignore the warning/error and continue execution. - after a stored routine instruction is executed: check for a remembered handler and activate one (if any). This logic caused several problems: - if one instruction generates several warnings (errors) it's impossible to choose the right handler -- a handler for the first generated condition was chosen and remembered for activation. - mess with handling conditions in scopes different from the current one. - not putting generated warnings/errors into Warning Info (Diagnostic Area) is against The Standard. The patch changes the logic as follows: - Diagnostic Area is cleared on the beginning of each statement that either is able to generate warnings, or is able to work with tables. - at the end of a stored routine instruction, Diagnostic Area is left intact. - Diagnostic Area is checked after each stored routine instruction. If an instruction generates several condition, it's now possible to take a look at all of them and determine an appropriate handler. mysql-test/r/signal.result: Update result file: 1. handled conditions are not cleared any more; 2. reflect changes in signal.test mysql-test/r/signal_demo3.result: Update result file: handled conditions are not cleared any more. Due to playing with max_error_count, resulting warning lists have changed. mysql-test/r/sp-big.result: Update result file: handled conditions are not cleared any more. mysql-test/r/sp-bugs.result: Update result file: handled conditions are not cleared any more. mysql-test/r/sp-code.result: Update result file: 1. handled conditions are not cleared any more. 2. add result for a new test case in sp-code.test. mysql-test/r/sp-error.result: Update result file: 1. handled conditions are not cleared any more. 2. add result for a new test case in sp-error.test. mysql-test/r/sp.result: Update result file: handled conditions are not cleared any more. mysql-test/r/sp_trans.result: Update result file: handled conditions are not cleared any more. mysql-test/r/strict.result: Update result file: handled conditions are not cleared any more. mysql-test/r/view.result: Update result file: handled conditions are not cleared any more. mysql-test/suite/funcs_1/r/innodb_storedproc_02.result: Update result file: handled conditions are not cleared any more. mysql-test/suite/funcs_1/r/memory_storedproc_02.result: Update result file: handled conditions are not cleared any more. mysql-test/suite/funcs_1/r/myisam_storedproc_02.result: Update result file: handled conditions are not cleared any more. mysql-test/suite/funcs_1/r/storedproc.result: Update result file: handled conditions are not cleared any more. mysql-test/suite/rpl/r/rpl_row_sp005.result: Update result file: handled conditions are not cleared any more. mysql-test/suite/rpl/r/rpl_row_sp006_InnoDB.result: Update result file: handled conditions are not cleared any more. mysql-test/suite/rpl/r/rpl_row_trig003.result: Update result file: handled conditions are not cleared any more. mysql-test/t/signal.test: Make a test case more readable in the result file. mysql-test/t/sp-code.test: Add a test case for Bug#23032 checking that No Data takes precedence on Warning. mysql-test/t/sp-error.test: Adding test cases for: - Bug#23032 - Bug#36185 - Bug#5889 - Bug#9857 mysql-test/t/sp.test: Fixing test case to reflect behavioral changes made by the patch. sql/sp_head.cc: Reset the per-statement warning count before executing a stored procedure instruction.

Patch for WL#2894: Make stored routine variables work
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;

A fix and a test case for Bug#6513 "Test Suite: Values inserted by using
cursor is interpreted latin1 character and Bug#9819 "Cursors: Mysql Server Crash while fetching from table with 5 million records." A fix for a possible memory leak when fetching into an SP cursor in a long loop. The patch uses a common implementation of cursors in the binary protocol and in stored procedures and implements materialized cursors. For implementation details, see comments in sql_cursor.cc include/my_sys.h: - declaration for multi_alloc_root libmysqld/Makefile.am: - drop protocol_cursor.cc, add sql_cursor.cc (replaces the old implementation of cursors with a new one) mysql-test/r/ctype_ujis.result: - test results fixed (a test case for Bug#6513) mysql-test/r/sp-big.result: - test results fixed (a test case for Bug#9819) mysql-test/t/ctype_ujis.test: Add a test case for Bug#6513 "Test Suite: Values inserted by using cursor is interpreted latin1 character" mysql-test/t/sp-big.test: Add a restricted test case for Bug#9819 "Cursors: Mysql Server Crash while fetching from table with 5 million records." mysys/my_alloc.c: - an implementation of multi_alloc_root; this is largely a copy-paste from mulalloc.c, but the function is small and there is no easy way to reuse the existing C function. sql/Makefile.am: - add sql_cursor.h, sql_cursor.cc (a new implementation of stored procedure cursors) and drop protocol_cursor.cc (the old one) sql/handler.cc: - now TABLE object has its mem_root always initialized. Adjust the implementation handler::ha_open sql/item_subselect.cc: - adjust to the changed declaration of st_select_lex_unit::prepare sql/protocol.h: - drop Protocol_cursor sql/sp_head.cc: - move juggling with Query_arena::free_list and Item::next to sp_eval_func_item, as this is needed in 3 places already. sql/sp_head.h: - declare a no-op implementation for cleanup_stmt in sp_instr_cpush. This method is needed for non-materializing cursors, which are yet not used in stored procedures. - declaration for sp_eval_func_item sql/sp_rcontext.cc: - reimplement sp_cursor using the new implementation of server side cursors. - use sp_eval_func_item to assign values of SP variables from the row fetched from a cursor. This should fix a possible memory leak in the old implementation of sp_cursor::fetch sql/sp_rcontext.h: - reimplement sp_cursor using the new implementation of server side cursors. sql/sql_class.cc: - disable the functionality that closes transient cursors at commit/rollback; transient cursors are not used in 5.0, instead we use materialized ones. To be enabled in a later version. sql/sql_class.h: - adjust to the rename Cursor -> Server_side_cursor - additional declarations of select_union used in materialized cursors sql/sql_derived.cc: - reuse bits of tmp table code in UNION, derived tables, and materialized cursors - cleanup comments sql/sql_lex.h: - declarations of auxiliary methods used by materialized cursors - a cleanup in st_select_lex_unit interface sql/sql_list.h: - add an array operator new[] to class Sql_alloc sql/sql_prepare.cc: - split the tight coupling of cursors and prepared statements to reuse the same implementation in stored procedures - cleanups of error processing in Prepared_statement::{prepare,execute} sql/sql_select.cc: - move the implementation of sensitive (non-materializing) cursors to sql_cursor.cc - make temporary tables self-contained: the table, its record and fields are allocated in TABLE::mem_root. This implementation is not clean and resets thd->mem_root several times because of the way create_tmp_table works (many additional things are done inside it). - adjust to the changed declaration of st_select_lex_unit::prepare sql/sql_select.h: - move the declaration of sensitive (non-materializing) cursors to sql_cursor.cc sql/sql_union.cc: - move pieces of st_select_unit::prepare to select_union and st_table methods to be able to reuse code in the implementation of materialized cursors sql/sql_view.cc: - adjust to the changed signature of st_select_lex_unit::prepare sql/table.cc: - implement auxiliary st_table methods for use with temporary tables sql/table.h: - add declarations for auxiliary methods of st_table used to work with temporary tables tests/mysql_client_test.c: - if cursors are materialized, a parallel update of the table used in the cursor may go through: update the test. sql/sql_cursor.cc: New BitKeeper file ``sql/sql_cursor.cc'' -- implementation of server side cursors sql/sql_cursor.h: New BitKeeper file ``sql/sql_cursor.h'' - declarations for server side cursors. |
