Shai Erera updated LUCENE-5440:
-------------------------------
Attachment: LUCENE-5440.patch
New patch:
* All lucene/ code is now cut over to (Long)FixedBitSet, including
ChainedFilter. What remains is OBS, test and iterator. I think I'll extract
FBS.iterator() to its own class, so that we could optimize in FBS.or() and
friends.
* OpenBitSetDISI is now unused, not in lucene/ nor solr/. Should I nuke it?
* I also moved some code which used FBS copy-constructor to grow an FBS to
FBS.ensureCapacity. So now nothing uses the new copy-constructor -- nuke it?
I think we can cutover Solr usage of OBS in a separate commit/patch/issue, to
make this issue contained.
> Add LongFixedBitSet and replace usage of OpenBitSet

> Spinoff from here: http://lucene.markmail.org/thread/35gw3amo53dsqsqj. I
> wrote a LongFixedBitSet which behaves like FixedBitSet, only allows managing
> more than 2.1B bits. It overcome some issues I've encountered with
> OpenBitSet, such as the use of set/fastSet as well the implementation of
> DocIdSet. I'll post a patch shortly and describe it in more detail.
