Re: Windows Bug?
Thanks! I just figured that out. I was passing true by mistake.

Re: Windows Bug?
The reason this is failing is because you are trying to create a new
index in the directory. It works on *nix file systems because you can
delete an open file on those operating systems, something you can't do
under Windows.
If you change the create parameter to false on your second call
everything should work as you expect it to.

Windows Bug?
Hi,
My understanding is that I can have an IndexReader open for searching
(as long as it doesn't delete) while an IndexWriter is updating the index.
I wrote a simple test app to prove this and it works great on Mac OS
X, Java 1.4.2 and Lucene 1.4.2. It fails on Windows XP, Java 1.4.2 and Lucene
1.4.2. I tried other versions of Lucene and it failed in those too.
This
is the app that fails on Windows:
public static void main(String[] args)
throws Exception {
String indexFolder = "/TestIndex";
// add
a document to the index
IndexWriter indexWriter = new IndexWriter
(indexFolder,
new StandardAnalyzer(), true);
Document document =
new Document();
Field field = new Field("foo", "bar",
true, true, true)
document.add(field);
indexWriter.addDocument(document);
indexWriter.close();
// open an index reader but don't close it
IndexReader indexReader =
IndexReader.open(indexFolder);
// open
an index writer
indexWriter = new IndexWriter
(indexFolder,
new StandardAnalyzer(), true);
indexWriter.close();
}
On Windows XP
this throws an Exception as soon as it tries to open the IndexWriter after
the IndexReader has been opened.
Here's the stack trace:
Exception in
thread "main" java.io.IOException: Cannot delete _1.cfs
at org.apache.lucene.store.FSDirectory.create(FSDirectory.java:144)
at org.apache.lucene.store.FSDirectory.getDirectory(FSDirectory.java:105)
at org.apache.lucene.store.FSDirectory.getDirectory(FSDirectory.java:83)
at org.apache.lucene.index.IndexWriter.(IndexWriter.java:173)
at scratch.TestLuceneLocks.main(TestLuceneLocks.java:17)
Is this a bug?
Thanks.
