Date Sun, 18 Mar 2012 22:24:41 GMT


Uwe Schindler updated LUCENE-3738:

    Attachment: LUCENE-3738.patch

I added a test, also checking ByteArrayDataInput and the exceptions.

I will commit this now and then backport.

> Today, write/readVInt "allows" a negative int, in that it will encode and decode correctly,
just horribly inefficiently (5 bytes).
> However, read/writeVLong fails (trips an assert).
> I'd prefer that both vInt/vLong trip an assert if you ever try to write a negative number...
it's badly trappy today.  But, unfortunately, we sometimes rely on this... had we had this
assert in 'since the beginning' we could have avoided that.
> So, if we can't add that assert in today, I think we should at least fix readVLong to
handle negative longs... but then you quietly spend 9 bytes (even more trappy!).
