I am getting following warning on mac os x:
partition.c:1800:24: warning: comparison of constant -1 with
expression of type 'NullTestType'
(aka 'enum NullTestType') is always false
[-Wtautological-constant-out-of-range-compare]
if (keynullness[i] == -1)
~~~~~~~~~~~~~~ ^ ~~
partition.c:1932:25: warning: comparison of constant -1 with
expression of type 'NullTestType'
(aka 'enum NullTestType') is always false
[-Wtautological-constant-out-of-range-compare]
if (keynullness[i] == -1)
~~~~~~~~~~~~~~ ^ ~~
2 warnings generated.
Comment for 0004 patch:
270 + /* -1 represents an invalid value of NullTestType. */
271 + memset(keynullness, -1, PARTITION_MAX_KEYS * sizeof(NullTestType));
I think we should not use memset to set a value other than 0 or true/false.
This will work for -1 on the system where values are stored in the 2's
complement but I am afraid of other architecture.
