Michael Busch commented on LUCENE-1044:
---------------------------------------
I think changing the only constructor in FSDirectory.FSIndexOutput is
an API change. I have a class that extends FSIndexOutput and it
doesn't compile anymore after switching to the 2.3-dev jar.
I think we should put this ctr back:
public FSIndexOutput(File path) throws IOException {
this(path, DEFAULT_DO_SYNC);
}

> When indexing a large number of documents, upon a hard power failure (e.g. pull the
power cord), the index seems to get corrupted. We start a Java application as an Windows Service,
and feed it documents. In some cases (after an index size of 1.7GB, with 30-40 index segment
.cfs files) , the following is observed.
> The 'segments' file contains only zeros. Its size is 265 bytes - all bytes are zeros.
> The 'deleted' file also contains only zeros. Its size is 85 bytes - all bytes are zeros.
> Before corruption, the segments file and deleted file appear to be correct. After this
corruption, the index is corrupted and lost.
> This is a problem observed in Lucene 1.4.3. We are not able to upgrade our customer deployments
to 1.9 or later version, but would be happy to back-port a patch, if the patch is small enough
and if this problem is already solved.
