------------------------------------
Summary: PackedQuadCell.getTokenBytesNoLeaf bug when null BytesRef
Key: LUCENE-7859
URL: https://issues.apache.org/jira/browse/LUCENE-7859
Project: Lucene - Core
Issue Type: Bug
Components: modules/spatial-extras
Reporter: David Smiley
Assignee: David Smiley
Fix For: master (7.0)
PackedQuadCell.getTokenBytesNoLeaf and PackedQuadCell.getTokenBytesWithLeaf
have a couple issues that were exposed in LUCENE-7845. One is that the WithLeaf
version actually modifies the state ({{long term}}) which it shouldn't. Another
is that if the BytesRef is null, it can compute a different result than if it's
not null, which is definitely wrong.
It _appears_ that these problems are only revealing themselves in practice with
the LUCENE-7845 optimization since there has been no PackedQuad test failure
before, and RandomSpatialOpFuzzyPrefixTreeTest really hammers the prefix tree.
