Deadlock case in IndexWriter on exception just before flush
-----------------------------------------------------------
Key: LUCENE-1208
URL: https://issues.apache.org/jira/browse/LUCENE-1208
Project: Lucene - Java
Issue Type: Bug
Components: Index
Affects Versions: 2.3.1, 2.3
Reporter: Michael McCandless
Assignee: Michael McCandless
Priority: Minor
Fix For: 2.4
If a document hits a non-aborting exception, eg something goes wrong
in tokenStream.next(), and, that document had triggered a flush
(due to RAM or doc count) then DocumentsWriter will deadlock because
that thread marks the flush as pending but fails to clear it on
exception.
I have a simple test case showing this, and a fix fixing it.
