SELECT used to read the index into a `long` variable, and then pass it to a function that takes an `int`, possibly causing an overflow before the range check. Now all these commands use better and cleaner range check, and that also results in a slight change of the error response in case of an invalid database index. SELECT: in the past it would have returned either `-ERR invalid DB index` (if not a number), or `-ERR DB index is out of range` (if not between 1..16 or alike). now it'll return either `-ERR value is out of range` (if not a number), or `-ERR value is out of range, value must between -2147483648 and 2147483647` (if not in the range for an int), or `-ERR DB index is out of range` (if not between 0..16 or alike) MOVE: in the past it would only fail with `-ERR index out of range` no matter the reason. now return the same errors as the new ones for SELECT mentioned above. (i.e. unlike for SELECT even for a value like 17 we changed the error message) COPY: doesn't really matter how it behaved in the past (new command), new behavior is like the above two. |
