OgreXMLConverter memory leaks

[Pulas]

It seems that the tool OgreXMLConverter has memory leaks.
I converted a mesh file to a xml file with memory track, whick detected memory leaks as below:

Code: Select all

Ogre Memory: Detected memory leaks !!! 
Ogre Memory: (51) Allocation(s) with total 4272 bytes.

After I added the following code, the OgreTechnique momory leak has gone.

Code: Select all

    Ogre::Pass::processPendingPassUpdates(); // make sure passes are cleaned

As for mesh, it seems that MeshManager does't delete all meshes they created.
When I add following code, the momory leaks still exist.

Code: Select all

m_pResourceGroupManager->shutdownAll();

After some debugging, I found the load state of mesh resource is wrong.

Code: Select all

    MeshPtr mesh = MeshManager::getSingleton().create("conversion", 
        ResourceGroupManager::DEFAULT_RESOURCE_GROUP_NAME);
    meshSerializer->importMesh(stream, mesh.getPointer());

the load state of mesh is LOADSTATE_UNLOADED.

Is this a bug?

Is this a bug?

If there is a memory leak (and it seems there is although I did not investigate it myself so far), it counts definitely as a bug. So please create a ticket on JIRA for it. Thanks.
