Lots of small fixes to multi-precision-math path Give Note for '123.4e' Added helper functions type 'val_string_from_real() Don't give warnings for end space for string2decimal() Changed storage of values for SP so that we can detect length of argument without strlen() Changed interface for str2dec() so that we must supple the pointer to the last character in the buffer BUILD/SETUP.sh: with-bdb ->with-berkeley-db include/decimal.h: Make string2decimal and string2decimal_fixed inline mysql-test/r/func_group.result: More tests (to find bugs in precision math fixes) mysql-test/r/func_set.result: Test to cover more Item_func_field::val_xxx() code mysql-test/r/ps_6bdb.result: update results mysql-test/r/type_decimal.result: New tests Give note for '123.4e' mysql-test/r/type_newdecimal.result: Number of decimal changes (probably right, but hard to verify) mysql-test/t/func_group.test: More tests (to find bugs in precision math fixes) mysql-test/t/func_set.test: Test to cover more Item_func_field::val_xxx() code mysql-test/t/type_decimal.test: New tests to cover more cases in decimal.c sql/item.cc: Added helper functions type 'val_string_from_real()' Use new interfase to str2my_decimal() Moved nr_of_decimals() here (and made it static) sql/item.h: Added helper functions type 'val_string_from_real()' sql/item_func.cc: Style fixes Trivial optimizations Ensure null_value is set if my_decimal_add/sub/mul/div returns error Remove not needed Item_func_int_div::val_str() Join Item_func_signproc and Item_func_neg Fix that FIELD() works when first argument is NULL or one if it's arguments are NULL new str2my_decimal interface sql/item_func.h: Make Item_func_int_div inherit from Item_int_func (allows us to remove some virtual functions) Join Item_func_signproc & Item_func_neg sql/item_strfunc.cc: Move nr_of_decmails() to Item.cc (as it was only used here) sql/item_sum.cc: Style fixes Change a lot of code to use new helper converter functions in item.cc Moved Item_sum::val_decimal() to Item_sum_int::val_decimal() Fixed calls to wrong functions (Item_sum_num::val_int()) Ensure that all hybrid functions checks hybrid_type in val_xxx() (As there is no gurantee that they are called in the right context) Simplify key_length allocation in Item_sum_sum_distinct() Simplified create_tmp_field() and reset_field() Fixed potential error in Item_sum_hybrid::reset_field() Optimize Item_sum_avg::update_field() Item_std_field() functions musted be fully coded becasue Item_variance_field::val_xxx functions called helper functions Coded missing Item_sum_ufd_xxx::val_decimal() functions sql/item_sum.h: Moved Item_sum::val_decimal() to Item_sum_int::val_decimal() Added missing Item_sum_ufd_xxx::val_decimal() functions Removed not used scale() function. Fixed that Item_std_field() works with decimal arguments Fixed that CREATE ... STD() will create a REAL field sql/log_event.cc: Ensure that we use same format for all types sql/my_decimal.cc: Don't give warnings for end space for string2decimal() Added dbug_print_decimal() sql/my_decimal.h: Style fixes Prototypes for new functions New interface for str2my_decimal() sql/mysql_priv.h: Made nr_of_decimals() static sql/protocol.cc: Simplify code (by assume that decimal can't be bigger than DECIMAL_MAX_STR_LENGTH] sql/protocol_cursor.cc: Changed storage of values for SP so that we can detect length of argument without strlen() sql/sp_head.cc: Simplify code for decimal handling by letting item handling conversion to decimal sql/sp_rcontext.cc: Use new method to get length of arguments sql/sql_analyse.cc: if -> switch Increase 'empty' if decimal value=0 Remove usage of strcat() sql/sql_base.cc: Remove unnecessary checks sql/sql_class.cc: Remove not needed 'else' Removed not used variables sql/sql_select.cc: remove test for impossible condtion strings/decimal.c: Made two trivial functions macros Changed interface for str2dec() so that we must supple the pointer to the last character in the buffer This safer than before as we don't require an end \0 anymore (old code gave wrong answers in MySQL for some internals strings that where not \0 terminated) Detect error numbers of type '12.55e' str2dec() will now set 'to' to zero in case of errors
