Eks Dev commented on LUCENE-1169:
---------------------------------
Thank you for fixing it in no time :) But...
I am getting confused with skipping iterators semantics,
is this requirement for the other DocIdSetIterators, of only for scorers
(should be, I guess)?
iterator.skipTo(iterator.doc()) <=> iterator.next();// is this contract?
if that is the case, we have another bug in OpenBitSetIterator (border
condition)
//this is the code in javadoc, "official contract"
boolean simulatedSkipTo(DocIdSetIterator i, int target) throws IOException {
do {
if (!i.next())
return false;
} while (target > i.doc());
return true;
}
public void testOpenBitSetBorderCondition() throws IOException {
OpenBitSet bs = new OpenBitSet();
bs.set(0);
DocIdSetIterator i = bs.iterator();
i.skipTo(i.doc());
assertEquals(0, i.doc()); //cool, moved to the first legal position
assertFalse("End of Matcher", i.skipTo(i.doc())); //NOT OK according to the
javadoc
}
public void testOpenBitSetBorderConditionSimulated() throws IOException {
OpenBitSet bs = new OpenBitSet();
bs.set(0);
DocIdSetIterator i = bs.iterator();
simulatedSkipTo(i, i.doc());
assertEquals(0, i.doc()); //cool, moved to the first legal position
assertFalse("End of Matcher", simulatedSkipTo(i, i.doc())); //OK according
to the javadoc!!
