Re: [cdt-dev] Antwort: Re: Add Monitor Button of Model Vew is disabled -- Impossible to view memory in debug view
Hello,

Here are the key parts:

  • The memory view is org.eclipse.debug.internal.ui.views.memory.MemoryView, and the classes in the same package
  • The interfaces representing the data model include org.eclipse.debug.core.model.IMemoryBlockRetrieval and org.eclipse.debug.core.model.IMemoryBlock
  • The interface that connects the platform memory model to the DSF memory model is org.eclipse.cdt.dsf.debug.internal.provisional.model.IMemoryBlockRetrievalManager
  • The interface for the memory service in DSF is org.eclipse.cdt.dsf.debug.service.IMemory

For those interface listed above you can use "Type Hierarchy" in Eclipse to explore the different implementations, depending on which versions of GDB. In the same order as above, the concrete classes are:
  • org.eclipse.cdt.dsf.gdb.internal.memory.GdbMemoryBlockRetrieval and org.eclipse.cdt.dsf.gdb.internal.memory.GdbMemoryBlock
  • org.eclipse.cdt.dsf.gdb.internal.memory.GdbMemoryBlockRetrievalManager
  • org.eclipse.cdt.dsf.gdb.service.GDBMemory (with some of the subclasses providing specialization for specific versions of GDB)

The above is the overview, you probably want breakpoints on:
  • AddMemoryBlockAction line: 395: "setEnabled(MemoryViewUtil.isValidContext(debugContext));"
  • RetargetAddMemoryBlockAction line: 67: updateAction(Object) method
to identify why/when the add memory action is not being enabled properly. 

I hope that helps.

Jonah

Hello Jonah,

thanks for the quick reply. I had selected the thread/frame from the "Debug" View but it didn't work. Did the same when I received your reply, but there is no change. Can you please let me know in which package this is implemented. I would like to debug the code is possible (When the Memory View is selected from the MenuItem Window -> Show view -> Memory.

Thanks and Regards,

Bewoayia

Hi Bewoayia,

The issue AFAICT is that your selection in the "Debug" view is gdb rather than a thread/frame for which you can examine memory on. Try selecting (in the Debug view) the Thread, that should make it work.

Hello,

 I am debugging a Hardware Simulation using eclipse and would like to read out some memory sections, but unfornately the button to add Monitors to the Memory View of the debug perspective is disabled. I built the Eclipse IDE from eclipse SDK/CDT (C/C++ Development Tools   9.5.3.20180803190).

 Can any one please let me know how to enable this? In which package or plugin is the Model View implemented.

 Attached is a screen shot or the issue.

 Thanks and Regards,

 Bewoayia
