Christian Danninger reopened LUCENE-6660:
-----------------------------------------
I double checked it. And everything should be fine with the index.
The index is fresh without deletions and child documents are added to parents
by the API:
{code}
SolrInputDocument child = new SolrInputDocument();
child.addField("parent", false);
child.addField("id", ++childId);
parent.addChildDocument(child);
{code}
I wrote an algorithm to check the index:
{code}
package test;
import java.io.IOException;
import java.nio.file.Path;
import java.nio.file.Paths;
import java.util.Collections;
import java.util.HashSet;
import org.apache.lucene.document.Document;
import org.apache.lucene.index.DirectoryReader;
import org.apache.lucene.store.FSDirectory;
import org.apache.lucene.store.MMapDirectory;
import org.apache.lucene.store.NRTCachingDirectory;
public class ParentChild {
public static void main(String[] args) throws IOException {
HashSet<String> unique = new HashSet<String>();
HashSet<String> parents = new HashSet<String>();
HashSet<String> children = new HashSet<String>();
HashSet<String> roots = new HashSet<String>();
Path path = Paths.get(args[0]);
FSDirectory directory = MMapDirectory.open(path);
NRTCachingDirectory nrtCachingDirectory = new
NRTCachingDirectory(directory, 48.0, 48.0);
DirectoryReader reader =
DirectoryReader.open(nrtCachingDirectory);
boolean wasChild = false;
String parentId = null;
for (int docID=0; docID<reader.maxDoc(); docID++) {
final Document document = reader.document(docID);
final String parent = document.get("parent");
final boolean isChild = parent.equals("F");
final boolean isParent = parent.equals("T");
final String root = document.get("_root_");
final String id = document.get("id");
// unique id ?
if (unique.contains(id)) {
throw new IllegalArgumentException();
}
if (root != null) {
roots.add(root);
}
if (isChild) {
// parent after its children?
if (parents.contains(root)) {
throw new IllegalArgumentException();
}
// correct parent ?
if (parentId != null && !parentId.equals(root))
{
throw new IllegalArgumentException();
}
children.add(id);
parentId = root;
} else {
if (wasChild) {
// children belong to parent ?
if (!id.equals(parentId)) {
throw new
IllegalArgumentException();
}
// ids matching ?
if (!id.equals(root)) {
throw new
IllegalArgumentException();
}
} else {
// parent without child
if (root != null) {
throw new
IllegalArgumentException();
}
}
if (!isParent) {
throw new IllegalArgumentException();
}
parents.add(id);
parentId = null;
}
unique.add(id);
wasChild = isChild;
}
System.out.println("docs: " + reader.maxDoc());
System.out.println("total: " + unique.size());
System.out.println("children: " + children.size());
System.out.println("parents: " + parents.size());
System.out.println("roots: " + roots.size());
System.out.println(Collections.disjoint(children, parents));
System.out.println(Collections.disjoint(children, roots));
System.out.println(parents.containsAll(roots));
System.out.println(reader.hasDeletions());
System.out.println(reader.isCurrent());
reader.close();
directory.close();
}
}
{code}
Output:
{code}
docs: 573397
total: 573397
children: 485949
parents: 87448
roots: 40342
