Robert Muir updated LUCENE-5975:
--------------------------------
Attachment: LUCENE-5975.patch
Patch. the fix is a one-line basically:
{code}
if (version >= VERSION_CHECKSUM) {
CodecUtil.checkFooter(input);
- } else {
+ } else if (version >= VERSION_DGAPS_CLEARED) {
CodecUtil.checkEOF(input);
- }
+ } // otherwise, before this we cannot even check that we read the entire
file due to bugs in those versions!!!!
assert verifyCount();
{code}
Patch is huge because the test includes all unique released versions of
BitVector.java from 3.x.
I think this is fine since it only applies for 4.10 branch anyway, we don't
have to carry this crap in trunk or 5.x
> Lucene can't read 3.0-3.3 deleted documents

> BitVector before Lucene 3.4 had many bugs, particulary that it wrote extra
> bogus trailing crap at the end.
> But since Lucene 4.8, we check that we read all the bytes... this check can
> fail for 3.0-3.3 indexes due to the previous bugs in those indexes, instead
> users will get exception on open like this: CorruptIndexException(did not
> read all bytes from file: read 5000 vs 5001....
