unknown	faad73550c	fix for bug #19690 : ORDER BY eliminates rows from the result Depending on the queries we use different data processing methods and can lose some data in case of double (and decimal in 4.1) fields. The fix consists of two parts: 1. double comparison changed, now double a is equal to double b if (a-b) is less than 50.1^(1 + max(a->decimals, b->decimals)). For example, if a->decimals==1, b->decimals==2, a==b if (a-b)<0.005 2. if we use a temporary table, store double values there as is to avoid any data conversion (rounding). mysql-test/r/type_float.result: fix for bug #19690: ORDER BY eliminates rows from the result - test result mysql-test/t/type_float.test: fix for bug #19690: ORDER BY eliminates rows from the result - test case sql/field.cc: fix for bug #19690: ORDER BY eliminates rows from the result - use not_fixed flag instead of dec to check bounds. sql/field.h: fix for bug #19690: ORDER BY eliminates rows from the result - Field_Double::not_fixed flag introduced, which is set if dec == NOT_FIXED_DEC and is used in the ::store() to check bounds. - new constructor introduced (with not_fixed_arg parameter). sql/init.cc: fix for bug #19690: ORDER BY eliminates rows from the result - fill log_01[] array with 0.1 powers. sql/item_cmpfunc.cc: fix for bug #19690: ORDER BY eliminates rows from the result - compare_real_fixed() and compare_e_real_fixed() introduced, they consider double a == double b if a-b is less than 'precision', 'precision' is set to 50.1^(1 + max(a->decimals, b->decimals)), for example, if a->decimals==1, b->decimals==2, 'precision' is 0.005 - use the above functions if both arguments are fixed. sql/item_cmpfunc.h: fix for bug #19690: ORDER BY eliminates rows from the result - Arg_comparator::presision introduced. - Arg_comparator::compare_real_fixed(), Arg_comparator::compare_e_real_fixed() introduced. sql/mysql_priv.h: fix for bug #19690: ORDER BY eliminates rows from the result - log_01 array of 0.1 powers added. sql/mysqld.cc: fix for bug #19690: ORDER BY eliminates rows from the result - log_01 array of 0.1 powers added. sql/sql_select.cc: fix for bug #19690: ORDER BY eliminates rows from the result - if we create double field in a temporary table, set not_fixed flag (use proper constructor) to avoid data conversion in the Field_double::store(). Otherwise we can lose some data.	19 years ago

unknown	2cbccbfb0c	Bug#24751 - Possible infinit loop in init_io_cache() when insufficient memory - When cache memory can't be allocated size is recaclulated using 3/4 of the requested memory. This number is rounded up to the nearest min_cache step. However with the previous implementation the new cache size might become bigger than requested because of this rounding and thus we get an infinit loop. - This patch fixes this problem by ensuring that the new cache size always will be smaller on the second and subsequent iterations until we reach min_cache. mysys/mf_iocache.c: - Added mask to cachesize to ensure that algorithm always produce a smaller cache size than current, until we reach 'min_cache' size.	19 years ago
