Subject [jira] Updated: (LUCENE-743) IndexReader.reopen()
Date Mon, 12 Nov 2007 10:28:50 GMT

     [ https://issues.apache.org/jira/browse/LUCENE-743?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Michael Busch updated LUCENE-743:
---------------------------------

    Attachment: lucene-743-take7.patch

Changes:

- Updated patch to current trunk (I just realized that the 
  latest didn't apply cleanly anymore)
- MultiSegmentReader now decRefs the subReaders correctly
  in case an exception is thrown during reopen()
- Small changes in TestIndexReaderReopen.java

The thread-safety test still sometimes fails. The weird
thing is that the test verifies that the re-opened 
readers always return correct results. The only problem
is that the refCount value is not always 0 at the end
of the test. I'm starting to think that the testcase
itself has a problem? Maybe someone else can take a look
- it's probably something really obvious but I'm already 
starting to feel dizzy while pondering about 
thread-safety.

> This is Robert Engels' implementation of IndexReader.reopen() functionality, as a set
of 3 new classes (this was easier for him to implement, but should probably be folded into
the core, if this looks good).
