Shai Erera updated LUCENE-3794:
-------------------------------
Attachment: LUCENE-3794.patch
Patch fixes the bug + adds a couple of test cases to ensure the correct
behavior.
> DirectoryTaxonomyWriter can lose the INDEX_CREATE_TIME property, causing
> DirTaxoReader.refresh() to falsely succeed (or fail)
> -----------------------------------------------------------------------------------------------------------------------------

> DirTaxoWriter sets createTime to null after it put it in the commit data
> once. But that's wrong because if one calls commit(Map<>) twice, the second
> time doesn't record the creation time. Also, in the ctor, if an index exists
> and OpenMode is not CREATE, the creation time property is not read.
> I wrote a couple of unit tests that assert this, and modified DirTaxoWriter
> to always record the creation time (in every commit) -- that's the only safe
> way.
> Will upload a patch shortly.
