Subject [jira] Updated: (LUCENE-2541) NumericRangeQuery errors with endpoints near long min and max values
Date Fri, 16 Jul 2010 21:33:52 GMT

Uwe Schindler updated LUCENE-2541:
----------------------------------

    Attachment: LUCENE-2541-uwe.patch

Here my solution (its yours), but different test. The tests in NumericRangeQuery also verify
that the range is really covered completely, so I tend to use these tests.

I just tried some values, we have to add randomness and other precsteps. Its just a start
before going to sleep - will extend tests tomorrow, to test different precSteps.

Yonik: The bug appears with 2^63 and, yes, it depends on precStep. What I meant is, that the
outer bounds must be in the "bracket" that covers the 2^63 limit. So with larger precision
steps, also smaller values overflow (but only for longs, ints are safe, as they internally
also use longs).
