[cdt-dev] Deleting breakpoints on terminate while updating markers

[Ramy Siha <ramysiha@xxxxxxxxx>]

Hello,
   I have an ILaunchesListener2.launchesTerminated function that deletes all the breakpoints as:

DebugPlugin
                                    .getDefault()
                                    .getBreakpointManager()
                                    .removeBreakpoints(
                                            DebugPlugin.getDefault()
                                                    .getBreakpointManager()
                                                    .getBreakpoints(), true);

I also have an DebugEventHandler.handleSuspend  function that fires a delta with IModelDelta.CONTENT flag

The problem is that on slow machines, when the the program gets suspended and the event with the model delta been handled, it triggers updates in the TreeModelContentProvider ( to redraw the breakpoints in the BreakpointsView )

if the user did press terminate while the update is still in progress ( since the update is in UI thread while the launchesTermiate is in the work ) I get the following exception:

org.eclipse.debug.core.DebugException: Breakpoint does not have an associated marker.

So the question is there is a way to wait for all breakpoint redraw operation to terminate before deleting the breakpoints, or is there is any workaround for this problem.

Note:
I'm working with CDT 7.0.2 & Eclipse 3.6.2
