Simon Willnauer updated LUCENE-3676:
------------------------------------
Attachment: LUCENE-3676.patch
here is a patch that merges multiple SortedSources on the fly using in
MultiDocValues. This allows to use SlowMRW etc. even with sorted DocValue
variants. I cut back to use SlowMRW if needed in TestSort and TestTypePromotion
and added a testcase to TestDocValuesIndexing to assert sorting etc.
I also generalized SortedBytesMergeUtils and used it in MultiDocValues to
implement the on-the-fly merging.
all tests pass :) yay!

> MultiDocValues doesn't support Sorted variant ie. SortedSource but throws
> UnsupportedOperationException. This forces users to work per segment. For
> consistency we should support sortedsource also if we wrap the DocValues in
> MDV.
