Subject [jira] [Commented] (LUCENE-4148) _TestUtil should be able to generate random longs
Date Mon, 18 Jun 2012 16:11:43 GMT


Dawid Weiss commented on LUCENE-4148:

This looks good to me, although I'm wondering how much randomness do we really need -- those
BigIntegers are worrying. I think this can be improved later if somebody wishes to dive into

Btw. an interesting random number generator --

> It would be helpful in TestPackedInts at least, in order to generate random values (as
a workaround, we currently generate a random int between 0 and {{min(Integer.MAX_VALUE, PackedInts.maxValue(bitsPerValue)}}).
Moreover, it would help to fix {{nextInt}} for large ranges (calling {{nextInt(random, -10,
Integer.MAX_VALUE)}} or even {{nextInt(random, 0, Integer.MAX_VALUE)}} currently fails because
the range of values is {{> Integer.MAX_VALUE}}.
