null

Key: LUCENE-3520
URL: https://issues.apache.org/jira/browse/LUCENE-3520
Project: Lucene - Java
Issue Type: Bug
Components: core/index
Reporter: Michael McCandless
Assignee: Michael McCandless
Fix For: 3.5, 4.0
I hit a failure in TestSearcherManager (NOTE: doesn't always fail):
{noformat}
ant test -Dtestcase=TestSearcherManager -Dtestmethod=testSearcherManager
-Dtests.seed=459ac99a4256789c:-29b8a7f52497c3b4:145ae632ae9e1ecf
{noformat}
It was tripping the assert inside SearcherLifetimeManager.record,
because two different IndexSearcher instances had different IR
instances sharing the same version. This was happening because
IW.getReader always returns a new reader even when there are no
changes. I think we should fix that...
Separately I found a deadlock in
TestSearcherManager.testIntermediateClose, if the test gets
SerialMergeScheduler and needs to merge during the second commit.
