[jira] Commented: (LUCENE-1700)
LogMergePolicy.findMergesToExpungeDeletes need to get deletes from the
SegmentReader
[ https://issues.apache.org/jira/browse/LUCENE-1700?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12721024#action_12721024 ]
Jason Rutherglen commented on LUCENE-1700:
------------------------------------------
Taking a step back, maybe we can solve the package protected
SegmentInfo issue here by creating a new class with the
necessary attributes?
Here's what LUCENE-1313 does:
{code} SegmentReader sr = writer.readerPool.getIfExists(info);
if (info.hasDeletions() || (sr != null && sr.hasDeletions())) {
{code}
Because SegmentInfo is package protected it seems ok to access a
package protected method (or in this case variable) in
IndexWriter.

> Key: LUCENE-1700
> URL: https://issues.apache.org/jira/browse/LUCENE-1700
> Project: Lucene - Java
> Issue Type: Bug
> Components: Index
> Affects Versions: 2.4.1
> Reporter: Jason Rutherglen
> Priority: Trivial
> Fix For: 2.9
>
> Original Estimate: 48h
> Remaining Estimate: 48h

> With LUCENE-1516, deletes are carried over in the SegmentReaders
> which means implementations of
> MergePolicy.findMergesToExpungeDeletes (such as LogMergePolicy)
> need to obtain deletion info from the SR (instead of from the
> SegmentInfo which won't have the information).
