Yonik Seeley updated SOLR-2861:
-------------------------------

    Attachment: fail13_postfix.xml

Here's a run  (fail13) w/ mixed hard+soft commits after Simon's patch.

{code}
14047  VERBOSE:WRITER5: start reopen without writer, reader= DirectoryReader(segments_6:1320156373422:nrt
_y(4.0):C78/7 _n(4.0):c2/1 _x(4.0):c11/1 _w(4.0):c1)
14184  VERBOSE:WRITER14: updateDocument id:98 Document<stored,indexed,indexOptions=DOCS_ONLY<id:98>
stored,indexed,tokenized,omitNorms,indexOptions=DOCS_ONLY<val_l:3>> org.apache.solr.update.SolrIndexWriter@43a4181c
14504  VERBOSE:WRITER14: updateDocument id:98 DONE
14523  VERBOSE:WRITER5: reopen result DirectoryReader(segments_6:1320156373425:nrt _y(4.0):C78/15
_n(4.0):c2/1 _x(4.0):c11/1 _w(4.0):c1 _z(4.0):C7)

### The update to id:98 may or may not be in the resulting reader above

14728  VERBOSE:WRITER8: start reopen from Searcher@28294f62 main{DirectoryReader(segments_6:1320156373425:nrt
_y(4.0):C78/15 _n(4.0):c2/1 _x(4.0):c11/1 _w(4.0):c1 _z(4.0):C7)} writer= org.apache.solr.update.SolrIndexWriter@43a4181c
14729  VERBOSE:WRITER8: reopen result (null)

### But this reopen shows no changes, so the update id:98 must be in reader 1320156373425

14920  VERBOSE:READER2: RealTimeGet using searcher  Searcher@79b0d33c main{DirectoryReader(segments_6:1320156373425:nrt
_y(4.0):C78/15 _n(4.0):c2/1 _x(4.0):c11/1 _w(4.0):c1 _z(4.0):C7)}
14922  VERBOSE:READER2: ERROR, id= 98 foundVal= 2 model val= 3 realTime= true

### Since we got the old value, we either missed the whole update, or just the delete part
of the update
(since the uniqueKey lookup stops at the first match, the new document may be in the index,
but we hit the old document first that wasn't marked as deleted)
