Task #3263
GMN node has the problem to handle the calling: mn.listObjects()
100%
Description
When I call mn.listObjects against a GMN node, I found the GMN give me a double size of the objects residing in it.
Chris Jones wrote a small test program:
package org.dataone.tests;
import java.util.List;
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.dataone.client.D1Client;
import org.dataone.client.MNode;
import org.dataone.service.exceptions.BaseException;
import org.dataone.service.types.v1.ObjectInfo;
import org.dataone.service.types.v1.ObjectList;
public class MNodeListObjectsTest {
/**
* @param args
*/
public static void main(String[] args) {
Log log = LogFactory.getLog(MNodeListObjectsTest.class);
log.debug("[" + Thread.currentThread().getName() + "] created.");
MNode mn = null;
mn = D1Client.getMN("https://mn-demo-1.test.dataone.org/knb/d1/mn");
try {
ObjectList list = mn.listObjects();
log.debug("list size: " + list.sizeObjectInfoList());
List<ObjectInfo> infoList = list.getObjectInfoList();
log.debug("infoList size: " + infoList.size());
} catch (BaseException e) {
e.printStackTrace();
}
}
}
This test works very well for the server https://mn-demo-1.test.dataone.org/knb/d1/mn.
However, when i change the mn base url to https://nibbler.nceas.ucsb.edu/mn, print out is:
list size: 20
infoList size: 20
However, the browser https://nibbler.nceas.ucsb.edu/mn/v1/object gave me:
The size doesn't match: one is 20, the other is 10.
So we guess GMN node has an issue to handle the mn.listObjects().

The two results not match is not due to the access control. First, i am the only one playing the GMN node and everything i put into the server is public readable. Second we tested twice against the GMN. The first time, the browser showed 33 objects and listObjects() showed 66 objects. And a print-out showed:
0the identifier is SNAP_PRC_CRU8bc5df22-ab45-4265-8158-c9402a1911cb
1the identifier is SNAP_PRC_CRU8bc5df22-ab45-4265-8158-c9402a1911cb
After deleting those objects in the GMN, i created another 10 objects. Then we tested again. This time the browser showed it 10 objects and listObjects() showed 20 objects. So each time the listObjects got the double size.

After talking with Roger and Rob, it looks like this may be an issue with MNode. It's odd that it works fine against mn-demo-1, and not nibbler. Assigning this to Rob to take a look.

hitting the /object endpoint from chrome, nibbler gives me 5 total objects. Using MNode in libclient, I get the same number (5), using the same two ways listed in the sample program.
MNode is giving the expected result, so the problem likely lies elsewhere.

Hi, Rob:
I ran the code which chrise wrote again ( a little bit modification). Here is the result:

You see the size is 10 and there are duplicate ids.
It is odd that yours worked, mine failed.

Roger and I did more test.
Accidentally, i found if there is no cilogon certificates in the tmp dir, the code will give you 5 objects. But if it has one, it will give you 10 objects.
Roger think the client will receive twice responds: one is as public and the other will be the authenticated user.
