Getting Invalid Registry Object while uninstalling plugins programatically [message #1138544]

When a specific condition is hit (while the user is trying to open our perspective), we uninstall the plugins using the below code:

Platform.getBundle(<Bundle name>).uninstall();

When we run this code on Juno 4.2.2, we are hitting the below exception. This same code was working well in Indigo and other earlier releases. Is there a possible step we need to perform before the uninstall? Any help soon will be appreciated.

Hi Anitha,
from looking at the stack trace I can see/assume the following:

The WorkbenchSourceProvider is updating the active shell. It is therefore requesting the perspectiveDescriptor of the current perspective. If you have already set your perspective (the one you are refering to in your post), then the descriptor is already known to the system. If we assume that this is the case then in the process of the WorkbenchActivityHelper to find out if access to the perspective should be restricted, the Helper is trying to resolve the perspective via the RegistryObjectManager. Since you have uninstalled your bundle with the perspective, it cannot be resolved. In the end this causes the exception:


public class RegistryObjectManager implements IObjectManager {
....
	private Object basicGetObject(int id, byte type) {
		Object result = cache.get(id);
		if (result != null)
			return result;
		if (fromCache)
			result = load(id, type);
/* here your exception is thrown */
		if (result == null)
			throw new InvalidRegistryObjectException();
		cache.put(id, result);
		return result;
	}
...
}

If you have not already done so, try switching to a valid perspective before uninstalling the bundle.

Hi Thorsten

I am also belong to same team

I tried switching to valid perspective before uninstalling but it did not work for me. I got the same error:Invalid registry object

public void uninstall_Plugins() {
MessageDialog.openInformation(shell, "hhhh",
"some text .");
PlatformUI.getWorkbench().getDisplay().asyncExec(new Runnable() {
public void run() {

IWorkbenchWindow w = PlatformUI.getWorkbench().getActiveWorkbenchWindow();

IPerspectiveRegistry reg = PlatformUI.getWorkbench().getPerspectiveRegistry();
String perspId = "org.eclipse.cdt.ui.CPerspective";
w.getActivePage().setPerspective(reg.findPerspectiveWithId(perspId));

try {
// Uninstalling the plugins
if (Platform.getBundle("persective id") != null) {

Platform.getBundle("").uninstall();
}

Thanks Thorsten for your hint. We tried closing the perspective and it works half way. We did the following to close the perspective before uninstalling the plugins

IWorkbenchWindow w = PlatformUI.getWorkbench().getActiveWorkbenchWindow();
if (w != null) {
IWorkbenchPage wp = w.getActivePage();
if (wp != null) {
IPerspectiveDescriptor[] p = wp.getOpenPerspectives();
if (p != null && p.length > 1) {
wp.closePerspective(p[p.length - 1], true, true);
}
}
}

After this change, we get back to the perspective we were in before we tried to change perspective and plugins got uninstalled. However when i try to bring up the perspective window again to check if the uninstalled perspective is not visible, i hit the Invalid Registry error again. Below is the trace.

Hi Arun,
sorry for answering late. I have now created a little setup to see what is happening in your case. I can confirm that the situation is different when running Indigo or Kepler. I have created an application that consists of two bundles. Each providing a perspective. Two commands with toolbar representations can be used to switch perspective and unregister the bundle. If running Indigo, the toolbar representations of the commands are removed when the respective bundle is uninstalled. It is just as expected. With Kepler this behaviour fails. So in Kepler it is not possible to unregister UI-Components provided by extensions. I dug into the code and found the following in PerspectiveRegistry:

public class PerspectiveRegistry implements IPerspectiveRegistry, IExtensionChangeHandler {

...
	public void removeExtension(IExtension source, Object[] objects) {
		// TODO compat: what do we do about disappearing extensions
	}
...

}

In Indigo you will find code that removes the uninstalled extension at that point. The same is true for other UI-Components. In Kepler I cannot for example find the code that uninstalls the commands. And indeed they also rise exceptions after the providing bundle is uninstalled.
So I think the compatibility feature you are looking for is currently not supported in Kepler.

Hi Arun,
sorry for answering late. Meanwhile I have created a sample application to see what happens in your case. I can confirm that the situation is different in Indigo and Kepler. The setup consists of two bundles. Each bundle providing a perspective and a view. In addition I have two commands represented by a toolbar button. The buttons can be used to switch perspective and uninstall a bundle. In Indigo the bundle is properly removed including all UI-Components (toolbar buttons and perspective). This is exactly what I would expect. In Kepler this does not hold true. I dug into the code and found the following in Kepler:

public class PerspectiveRegistry implements IPerspectiveRegistry, IExtensionChangeHandler {
...
   public void removeExtension(IExtension source, Object[] objects) {
      // TODO compat: what do we do about disappearing extensions
   }
...
}

In Indigo you find at this place code that removes the perspective from the registry. I also cannot find the code that removes the commands from the Registry in Kepler. So I would say that the uninstall feature of UI-Components provided via extensions is currently (at least partly) not supported by the compatibility layer of Kepler.

Hi Arun,
sorry for answering late. Meanwhile I have created a test application to see what happens in your example.
I can confirm that the situation is different in Indigo (3.7.2) and Kepler (4.2). My setup constists of two bundles, each providing
a perspective and a view. In addition I have two commands represented by a toolbar button. They can be used to switch
perspective and uninstall a bundle. In Indigo the uninstall process removes the perspective and the toolbar buttons
correctly. There is no exception thrown afterwards. This does not hold true for Kepler. The toolbar buttons are still
visible after uninstalling the providing bundle. I dug into the code and found the following code in PerspectiveRegistry:

public class PerspectiveRegistry implements IPerspectiveRegistry, IExtensionChangeHandler {
...
	public void removeExtension(IExtension source, Object[] objects) {
		// TODO compat: what do we do about disappearing extensions
	}
...
}

So in Kepler the perspective extension is not properly removed from the registry. (In Indigo you will find at this place
code that really removes the extension from the registry.) I can also not find the code that removes the commands from
the registry. So I would conclude that the required compatibility feature that uninstalls UI-Components provided by
extensions is at least partly not provided by Kepler.
