Michael McCandless updated LUCENE-1143:
---------------------------------------
Attachment: LUCENE-1143.patch
Attached patch. All tests pass. I created more unit tests in
TestIndexWriter to test hitting a single IOException, at different
points, and then NOT hitting anymore exceptions, and verifying we can
close & open a reader successfully.
The fix itself is trivial and low risk.
I think this is serious enough to re-spin 2.3.
I will commit shortly to trunk & port to 2.3 branch.

> I hit this in working on LUCENE-1044.
> If you disk full event during flush, then DocumentsWriter will abort
> (clear all buffered docs). Then, if you then add another doc or two,
> and then close your writer, and this time succeed in flushing (say
> because it's only a couple buffered docs so the resulting segment is
> smaller), you can flush a corrupt segment (that incorrectly has a
> non-zero docStoreOffset).
> I modified the TestConcurrentMergeScheduler test to show this bug.
> I'll attach a patch shortly.
