- unsigned flag was not handled correctly for a number of mathematical funcions, which led to incorrect results - passing large values as the number of decimals to ROUND() resulted in incorrect results and even server crashes in some cases - reverted the fix and the testcase for bug #10083 as it violates the manual - fixed some testcases which relied on broken ROUND() behavior mysql-test/r/func_math.result: - Removed the testcase for bug #10083 (not a bug according to the manual) - Changed the testcase for bug #9837 to expect a correct ROUND() behavior - Added testcases for bug #24912 and all related bugs found mysql-test/r/type_newdecimal.result: Fixed a truncate() testcase which relied on broken behavior mysql-test/t/func_math.test: - Removed the testcase for bug #10083 (not a bug according to the manual) - Changed the testcase for bug #9837 to expect a correct ROUND() behavior - Added testcases for bug #24912 and all related bugs found sql/item_func.cc: Various changes to fix bug #24912 and all related bugs found: - honor unsigned_flag in various Item_* functions - correctly handle out-of-range numbers of decimals in Item_func_round::fix_length_and_dec() - changed the argument specifying the number of decimals in my_double_round() from int to longlong, added a new argument to pass the 'unsigned flag' - changed my_double_round() to correctly handle large values passed as the 'number of decimals' argument - added a my_double_round() analog for BIGINT UNSIGNED arguments (my_unsigned_round()) - fixed Item_func_round()::int_op() to not overflow even when the result is within integer range - fixed a bug Item_founc_round()::decimal_op() which resulted in crash when a large number of decimals was passed to my_decimal_round() sql/item_func.h: Various fixed to correctly handle unsigned values. sql/item_strfunc.cc: Changed the call to my_double_round() to match the new declaration. sql/mysql_priv.h: Changed the declaration for my_double_round() to be able pass arbitrary integers as number of decimals (both signed and unsigned)
