Subject [jira] [Commented] (LUCENE-3403) Term vectors missing after addIndexes + optimize
Date Fri, 26 Aug 2011 11:16:29 GMT


Simon Willnauer commented on LUCENE-3403:

bq.You're right, it does not happen on trunk. I still want to commit the test cases to trunk
too, so that we've got that covered there as well. Therefore I think I should keep the 4.0
fix version?

don't get me wrong I was just double checking because 4.0 was not in the affected version.
I don't wanna miss such a trap. :)

bq. The problem is that SegmentMerger receives its FieldInfos from DocumentsWriter, and it
knows whether to set hasVector according to what it receives. When you addDoc, DW has FieldInfos,
but when you only addIndexes, DW doesn't.

maybe we should adopt what trunk does, checking all the FI if one of the stores vectors unless
you FIs is readonly?

bq. If it's ok, I'll commit the fix to 3x and the tests-only to trunk.

+1 tests are great!

> I encountered a problem with addIndexes where term vectors disappeared following optimize().
I wrote a simple test case which demonstrates the problem. The bug appears with both addIndexes()
versions, but does not appear if addDocument is called twice, committing changes in between.
> I think I tracked the problem down to IndexWriter.mergeMiddle() -- it sets term vectors
before merger.merge() was called. In the addDocs case, merger.fieldInfos is already populated,
while in the addIndexes case it is empty, hence fieldInfos.hasVectors returns false.
