IndexWriter.unlock does does nothing if NativeFSLockFactory is used
-------------------------------------------------------------------
Key: LUCENE-2104
URL: https://issues.apache.org/jira/browse/LUCENE-2104
Project: Lucene - Java
Issue Type: Bug
Reporter: Shai Erera
Fix For: 3.1
If NativeFSLockFactory is used, IndexWriter.unlock will return, silently doing
nothing. The reason is that NativeFSLockFactory's makeLock always creates a new
NativeFSLock. NativeFSLock's release first checks if its lock is not null.
However, only if obtain() is called, that lock is not null. So release actually
does nothing, and so IndexWriter.unlock does not delete the lock, or fail w/
exception.
This is only a problem in NativeFSLock, and not in other Lock implementations,
at least as I was able to see.
Need to think first how to reproduce in a test, and then fix it. I'll work on
it.
