Shai Erera updated LUCENE-5440:
-------------------------------
Attachment: LUCENE-5440-solr.patch
Patch moves solr/ code to use FixedBitSet instead of OpenBitSet. I ran into few
issues e.g. w/ bulk operations such as or/union, where OpenBitSet grew the
underlying long[]. Now it needs to grow on the outside. I think I'll add a
check to FBS.or() to make sure the given bitset is not bigger than the current
one.
Anyway, I still didn't run tests, just wanted to checkpoint. There are no more
uses of OBS in solr/.

> 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.
