Subject [jira] Updated: (SOLR-1111) fix FieldCache usage in Solr
Date Mon, 25 May 2009 17:06:45 GMT

     [ https://issues.apache.org/jira/browse/SOLR-1111?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Yonik Seeley updated SOLR-1111:
-------------------------------

    Attachment: SOLR-1111_sort.patch

Attaching SOLR-1111_sort.patch to use new Lucene Collector classes, including sorting collectors
that will use FieldCache entries at the segment level instead of the top level reader.

Unfortunately, tests don't currently pass - NPE caused by sort=a_i asc.
Looks like we'll need to port any custom comparators over to the new FieldComparatorSource
(I hadn't thought about this before, but of course it makes sense that the old custom comparators
wouldn't work since there isn't a method to compare docs from different segments).

> Recent changes in Lucene have altered how the FieldCache is used and as-is could lead
to previously working Solr installations blowing up when they upgrade to 1.4.  We need to
fix, or document the affects of these changes.
