The cmp() function used to compare btree keys was using the trick of comparing unsigned values by coercing the result of subtraction to a signed type. This is fine as long as the range of differences never actually exceeds the limits of the signed type. For instance, with int64, as long as the magnitude of the difference is under 2^63 or so, it works reasonably well. Plain int, however, can be a 32-bit type, at which point the magnitude of difference needed to break it is only 2^31 or so. Subtraction and type conversion is enough cheaper than branches that this is worth preserving, but it's worth preserving by switching to an explicit int64 for the operation and return type. This will not actually affect performance except for people using the btree code on 32-bit machines, so it probably won't ever matter. Which may also be true of the potential wrong answers, but "might be slower" is a better risk than "might crash". |
