Ferenczi Jim updated LUCENE-7569:
---------------------------------
Attachment: LUCENE-7569.patch
It turns out that the problem is a just a test bug related to
MockRandomMergePolicy. This merge policy is only used in tests and randomly
wraps the reader to be merged in a SlowCodecReaderWrapper in order to
deactivate the bulk merging. The test pass if I add a MergeReaderWrapper around
the original reader. This makes index sorting happy since the docvalues
instances are now re-created each time.
Bottom line is that merging of multi-valued docvalues works fine even when
index sorting is on except in these tests where the MockRandomMergePolicy
disables the bulk merge.
I've attached a patch that fixes this bug and the other test bug on
testNumericAlreadySorted. The patch is for the master branch (since
testNumericAlreadySorted should also fail on this branch) but the backport
should be straightforward.
