Fixes after merge with 4.1
FOUND is not a reserved keyword anymore Added Item_field::set_no_const_sub() to be able to mark fields that can't be substituted Added 'simple_select' method to be able to quickly determinate if a select_result is a normal SELECT Note that the 5.0 tree is not yet up to date: Sanja will have to fix multi-update-locks for this merge to be complete BUILD/SETUP.sh: Portability fix client/mysqltest.c: Portability fix mysql-test/r/drop.result: updated results mysql-test/r/func_str.result: New warnings (after merge) mysql-test/r/insert.result: Updated tests mysql-test/r/join_nested.result: Updated results (because of new column types in 5.0) mysql-test/r/lock_multi.result: Temporarly wrong results until Sanja fixes multi-update-lock in 5.0 mysql-test/r/multi_update.result: Temporary fix until Sanja fixes multi-update locking mysql-test/r/ps_1general.result: Update of results after merge mysql-test/r/ps_2myisam.result: Update of results after merge mysql-test/r/ps_3innodb.result: Update of results after merge mysql-test/r/ps_4heap.result: Update of results after merge mysql-test/r/ps_5merge.result: Update of results after merge mysql-test/r/ps_6bdb.result: Update of results after merge mysql-test/r/query_cache.result: Update of results after merge mysql-test/r/range.result: New results for new tests mysql-test/r/rpl_auto_increment.result: Update with new 4.0 information mysql-test/r/rpl_charset.result: After merge fixes mysql-test/r/subselect.result: After merge fixes mysql-test/r/view.result: Temporary fix until multi-update-locking is fixed mysql-test/t/drop.test: Safety fix mysql-test/t/multi_update.test: Temporary fix until multi-update-locking is fixed mysql-test/t/rpl_charset.test: More comments mysql-test/t/sp-error.test: Updated comments mysql-test/t/view.test: Temporary fix until multi-update-locking is fixed scripts/mysql_fix_privilege_tables.sh: Better error message sql-common/client.c: More debugging sql/ha_ndbcluster.cc: After merge fixes sql/handler.cc: After merge fixes sql/item.cc: Simple optimization of creating item After merge fixed Added Item_field::set_no_const_sub() to be able to mark fields that can't be substituted The problem is that if you compare a string field to a binary string, you can't replace the field with a string constant as the binary comparison may then fail (The original field value may be in a different case) sql/item.h: Added Item::set_no_const_sub() to be able to mark fields that can't be substituted sql/item_cmpfunc.cc: Mark fields compared as binary to not be substituted. sql/item_func.cc: After merge fix sql/log_event.cc: After merge fix sql/mysql_priv.h: After merge fix sql/opt_range.cc: After merge fix sql/protocol.cc: Made flags uint instead of int (as it's used as a bit mask) sql/protocol.h: Made flags uint instead of int (as it's used as a bit mask) sql/protocol_cursor.cc: Made flags uint instead of int (as it's used as a bit mask) Indentation cleanups sql/sp.cc: After merge fixes Removed compiler warnings sql/sp_head.cc: After merge fixes sql/sql_base.cc: After merge fixes Removed 'send_error' from 'insert_fields()' as the error is sent higher up sql/sql_class.cc: Give assert if set_n_backup_item_arena is used twice sql/sql_class.h: Give assert if set_n_backup_item_arena is used twice After merge fixes Added 'simple_select' method to be able to quickly determinate if a select_result is a normal SELECT sql/sql_handler.cc: After merge fixes sql/sql_parse.cc: After merge fixes sql/sql_prepare.cc: After merge fixes sql/sql_select.cc: After merge fixes Moved 'build_equal_items' to optimize_cond() (logical place) sql/sql_table.cc: After merge fixes sql/sql_trigger.cc: After merge fixes sql/sql_update.cc: After merge fixes (This should be fixed by Sanja to have lower granuality locking of tables in multi-update) sql/sql_view.cc: After merge fixes sql/sql_yacc.yy: After merge fixes Don't have FOUND as a reserved keyword
