Uwe Schindler updated LUCENE-1948:
----------------------------------
Fix Version/s: (was: 3.0)
3.1
I move this to 3.1. The writer was already transformed to the new TokenStream
API (not really effective, but works). We can deprecate it it 3.1 if needed.

> I suppose that should have been suggested before 2.9 rather than
> after...
> There are at least three reasons to why I want to do this:
> The code is based on the behaviour or the Directory IndexWriter as of
> 2.3 and I have not been touching it since then. If there will be
> changes in the future one will have to keep IIW in sync, something
> that's easy to forget.
> There is no locking which will cause concurrent modification
> exceptions when accessing the index via searcher/reader while
> committing.
> It use the old token stream API so it has to be upgraded in case it
> should stay.
> The java- and package level docs have since it was committed been
> suggesting that one should consider using II as if it was immutable
> due to the locklessness. My suggestion is that we make it immutable
> for real.
> Since II is ment for small corpora there is very little time lost by
> using the constructor that builts the index from an IndexReader. I.e.
> rather than using InstantiatedIndexWriter one would have to use a
> Directory and an IndexWriter and then pass an IndexReader to a new
> InstantiatedIndex.
> Any objections?
