The beleaguered WT_STRING_MATCH macro has an error when the second string is zero length.
#include <stdio.h>
#include <string.h>
#include <stdbool.h>
#define WT_STRING_MATCH(str, bytes, len) __wt_string_match(str, bytes, len)
static inline bool
__wt_string_match(const char *str, const char *bytes, size_t len)
{
return (len == 0 || (strncmp(str, bytes, len) == 0 && str[len] == '\0'));
}
void main(void) {
const char *nothing = "";
printf("returns %d\n", WT_STRING_MATCH("something", nothing, 0));
}
This prints 1, that is, true. In the way this macro is used, this should behave differently from memcmp, not the same.
