Troubles using TraversalDFS (DEX Java)

[gregorio...@gmail.com]

I’m having troubles using TraversalDFS (I’m using DEX on java). I can create the graph successfully and then i use TraversalDFS and it works fine but when i try to close the session i’m getting this error:

Exception in thread “main” java.lang.RuntimeException: Session data still active when closing
at com.sparsity.dexjavawrapJNI.delete_dex_gdb_Session(Native Method)
at com.sparsity.dex.gdb.Session.delete(Session.java:32)
at com.sparsity.dex.gdb.Session.close(Session.java:40)

I checked everything many times and i think the code is fine because i use exactly the same code changing TraversalDFS by TraversalBFS and it works fine.

Please i need help

Hi,

Which operating system are you using?

Could you please contact dam...@sparsity-technologies.com with more details?
We may need to know what other dex api methods are you using in the traversal, specially iterators and update operations.

Thanks.

My operating system is Linux (Ubuntu 12.04) but i'm running test on a Debian machine and i'm getting the same error in both.

This is the code that isn't working for me:

try

...

String path = "graphs/DB/dexdb/2";

DexConfig cfg = new DexConfig();

cfg.setLicense("XXXX-XXXX-XXXX");

Dex dex = new Dex(cfg);

Database db = dex.open(path+"/DexBD.dex", true); // Opening some graph created previously

Session sess = db.newSession();

Graph g = sess.getGraph();

int NodeType; //Node's ids

int NodeIdType; //Node Attribute's ids

            

NodeType = g.findType("NODE"); // I have only this type of nodes in the graph

NodeIdType = g.findAttribute(NodeType, "ID"); //All nodes have this attribute

            

String src = "252", dst = "685";

Value value = new Value();

long curr, dstO;

boolean found = false;

dstO = g.findObject(NodeIdType, value.setString(dst));

TraversalDFS dfs = new TraversalDFS(sess, g.findObject(NodeIdType, value.setString(src)));

dfs.addAllNodeTypes();

dfs.addAllEdgeTypes(EdgesDirection.Outgoing);

while (dfs.hasNext() && !found) {

         curr = dfs.next();

         if (curr == dstO) found = true;

}

dfs.close();

            

sess.close(); // HERE IS THE ERROR

db.close();

dex.close();

catch

...

You are right!
There is a problem at the TraversalDFS close operation that is causing this error.
It should be fixed in the release 4.8.2 that will soon be published along with other minor bug fixes.

But, if you can't wait until the official publication of the 4.8.2 release, you can ask damaris@sparsity-technologies.com to send you a pre-release for your platform.

Best regards.
