Relevant snipped of test case extracted below:
scoped_ptr<HarnessHelper> harnessHelper( newHarnessHelper() ); scoped_ptr<SortedDataInterface> sorted( harnessHelper->newSortedDataInterface() ); scoped_ptr<OperationContext> opCtx( harnessHelper->newOperationContext() ); WriteUnitOfWork uow( opCtx.get() ); ASSERT_OK( sorted->insert( opCtx.get(), key1, loc1, false ) ); ASSERT_OK( sorted->insert( opCtx.get(), key1, loc2, true /* allow duplicates */ ) ); ASSERT_OK( sorted->insert( opCtx.get(), key1, loc3, true /* allow duplicates */ ) ); uow.commit(); scoped_ptr<SortedDataInterface::Cursor> cursor( sorted->newCursor( opCtx.get(), -1 ) ); cursor->locate( key1, loc2 ); vector<const BSONElement*> keyEnd( 1 ); vector<bool> keyEndInclusive( 1 ); cursor->advanceTo( key1, 1, false, keyEnd, keyEndInclusive ); ASSERT_EQUALS( key1, cursor->getKey() ); ASSERT_EQUALS( loc1, cursor->getDiskLoc() );
Instead, the cursor is positioned at (key1, loc3), i.e. the last occurrence of the specified key in the index.
