Steve Rowe updated SOLR-5652:
-----------------------------
Attachment: 372.log
I see the same pattern (missing value docvalue sorting as if it had a value of
zero, or zero-length in the string case) in all the other failed trials:
trial #330: sort=double_dv_first+desc; missing value doc id=53 is the first doc
on page one, and is also given as one of six missing value docs at the zero
position on page three.
trial #358: sort=double_dv_last+asc; missing value doc id=53 is given as one of
five missing value docs at the zero position on page three, and then again as
the last doc on page seven.
trial #372: sort=str_dv_last+desc; missing value doc id=45 is mentioned on two
different pages, and missing str_dv_last value docs are sorted at the same
position as, and interleaved with, zero-length value docs. I've attached the
full log for this one ({{372.log}}).

> Twice now, Uwe's jenkins has encountered a "walk already seen ..." assertion
> failure from DistribCursorPagingTest that I've been unable to fathom, let
> alone reproduce (although sarowe was able to trigger a similar,
> non-reproducible seed, failure on his machine)
> Using this as a tracking issue to try and make sense of it.
> Summary of things noticed so far (in 3 failures):
> * So far only seen on http://jenkins.thetaphi.de & sarowe's mac
> * So far only seen on MacOSX
> * So far only seen on branch 4x
> * So far seen on both Java6 and Java7
> * fails occured in first block of randomized testing:
> ** we've indexed a small number of randomized docs
> ** we're explicitly looping over every field and sorting in both directions
> * fails were both when doing a "desc" sorting on one of the "\*_dv_last" or
> "\*_dv_first" fields (docValues=true, either sortMissingLast=true OR
> sortMissingFirst=true)
> ** sort on same field asc has always worked fine just before this (fields are
> in arbitrary order, but "asc" always tried before "desc")
> ** sorting on some other random fields has sometimes been tried before this
> and worked
> (specifics of each failure seen in the wild recorded in comments)
