myisamchk tool generates warnings when run on an myisam files (.MYI or .MYD) This is because of the conversion of max_value for certain options in myisamchk from singed long to unsigned long The max value for the options key_buffer_size, read_buffer_size, write_buffer _size and sort_buffer_size is given as (long) ~0L which becomes -1 when casted from signed long to longlong and then casted to ulonglong. When (ulonglong) -1 is compared with maximal value for GET_ULONG data type, we adjust it to (ulonglong) ULONG_MAX and throw the warning. Fixed by using the right max size. Max values for the variables (from mysqld.cc) ---------------------------- 1. key_buffer_size 5.0: ULONG_MAX 5.1: SIZE_T_MAX 6.0: SIZE_T_MAX 2. read_buffer_size and write_buffer_size 5.0: INT_MAX32 5.1: INT_MAX32 6.0: INT_MAX32 3. sort_buffer_size (aka myisam_sort_buffer_size) 5.0: UINT_MAX32 5.1: ULONG_MAX 6.0: ULONG_MAX Note: testcase not attached
