Subject [jira] [Commented] (LUCENE-4148) _TestUtil should be able to generate random longs
Date Sun, 17 Jun 2012 22:49:42 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-4148?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13393632#comment-13393632

Adrien Grand commented on LUCENE-4148:
--------------------------------------

It seems to me that {{min}} and {{max}} are inclusive in both methods.

@Dawid could RandomInts have a similar method to generate longs? Something like 
{code}
  public static long randomLongBetween(Random r, long min, long max);
{code}

> 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}}.
