Barakat Barakat updated LUCENE-4583:
------------------------------------
Attachment: LUCENE-4583.patch
I recently switched from 4.1 to 4.3, and my patch needed to be updated because
of the changes to DocValues. The problem was almost fixed for BinaryDocValues,
but it just needed one little change. I've attached a patch that removes the
BinaryDocValues exception when the length is over BYTE_BLOCK_SIZE (32k), fixes
ByteBlockPool#readBytes:348, and changes the
TestDocValuesIndexing#testTooLargeBytes test to check for accuracy.
> StraightBytesDocValuesField fails if bytes > 32k

> Components: core/index
> Affects Versions: 4.0, 4.1, 5.0
> Reporter: David Smiley
> Priority: Critical

> I didn't observe any limitations on the size of a bytes based DocValues field
> value in the docs. It appears that the limit is 32k, although I didn't get
> any friendly error telling me that was the limit. 32k is kind of small IMO;
> I suspect this limit is unintended and as such is a bug. The following
> test fails:
> {code:java}
> public void testBigDocValue() throws IOException {
> Directory dir = newDirectory();
> IndexWriter writer = new IndexWriter(dir, writerConfig(false));
> Document doc = new Document();
> BytesRef bytes = new BytesRef((4+4)*4097);//4096 works
> bytes.length = bytes.bytes.length;//byte data doesn't matter
> doc.add(new StraightBytesDocValuesField("dvField", bytes));
> writer.addDocument(doc);
> writer.commit();
> writer.close();
> DirectoryReader reader = DirectoryReader.open(dir);
> DocValues docValues = MultiDocValues.getDocValues(reader, "dvField");
> //FAILS IF BYTES IS BIG!
> docValues.getSource().getBytes(0, bytes);
> reader.close();
> dir.close();
> }
> {code}
