Subject [jira] [Commented] (LUCENE-7179) GeoPoint and LatLonPoint test data should quantize once
Date Tue, 05 Apr 2016 18:12:25 GMT


Robert Muir commented on LUCENE-7179:

If you're referring to TestEncodingUtils.testEncodeDecodeRoundsDown it passes fine with the
LUCENE-7164 64 bit space change.

No I am not: that test is relatively worthless because it does not test, and *will never test*
the values that are buggy. If you fix it to look like LatLonPoint's, it will fail, and it
will fail with the new encoding on LUCENE-7164 too.

> {{LatLonPoint}} and {{GeoPointField}} tests pre quantizes test data to ensure consistency
with indexed (encoded) data. The pre quantized data then becomes indexed, undergoing another
quantization. To guarantee numerical stability this should be changed such that the test data
is quantized after indexing.
