Shai Erera updated LUCENE-2480:
-------------------------------
Attachment: LUCENE-2480.patch
Thanks Earwin ! Few comments:
* You didn't remove the .zip indexes?
* You removed the code from TestBackwardsCompatibilty which creates the older
indexes. While this isn't needed currently for trunk - the code is commented
out, and I don't think it bothers anyone - one day, after 4.0 is released, we
will need to use it. So I don't think we should remove that piece of code.
* TestIndexFileDeleter failed 'cause of deletable file - fixed it.
Attached is the merged patch, w/ the above fixes. Solr tests fail
(*.dataimport.* tests) for some reason. I don't understand this yet - so if
someone more knowledgeable about Solr than me cares to take a look, I'd
appreciate it. I see many things like that (not sure how those tests are
related to this issue):

> Remove support for pre-3.0 indexes

> We should remove support for 2.x (and 1.9) indexes in 4.0. It seems that
> nothing can be done in 3x because there is no special code which handles 1.9,
> so we'll leave it there. This issue should cover:
> # Remove the .zip indexes
> # Remove the unnecessary code from SegmentInfo and SegmentInfos. Mike
> suggests we compare the version headers at the top of SegmentInfos, in 2.9.x
> vs 3.0.x, to see which ones can go.
> # remove FORMAT_PRE from FieldInfos
> # Remove old format from TermVectorsReader
> If you know of other places where code can be removed, then please post a
> comment here.
> I don't know when I'll have time to handle it, definitely not in the next few
> days. So if someone wants to take a stab at it, be my guest.
