Subject [jira] Commented: (LUCENE-1314) IndexReader.reopen(boolean force)
Date Sat, 12 Jul 2008 00:33:31 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-1314?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12613025#action_12613025

Michael McCandless commented on LUCENE-1314:
--------------------------------------------

bq. Because Ocean does not flush to disk with every transaction (deleteDocument then clone
the reader) there is a need to allow cloning of readers that have not flushed changes.

But when you clone a reader with pending changes, is the old reader's write lock revoked?
 Meaning it is not allowed to commit (yet, continues to hold the changes it has)?  And the
newly cloned reader gets the write lock?  Are further changes allowed against the old reader,
or maybe it should become "frozen"?

> Based on discussion http://www.nabble.com/IndexReader.reopen-issue-td18070256.html. 
The problem is reopen returns the same reader if there are no changes, so if docs are deleted
from the new reader, they are also reflected in the previous reader which is not always desired
behavior.
