            Bug ID: 28941
           Summary: Say what 'that' is: You can't do that without a
                    process to debug.:
           Product: gdb
           Version: 10.1
            Status: NEW
          Severity: normal
          Priority: P2
         Component: gdb
          Assignee: unassigned at sourceware dot org
          Reporter: dgilbert at redhat dot com
  Target Milestone: ---

I'm using some python scripts that come with qemu and using them on a core and
I get a:
Python Exception <class 'gdb.error'> You can't do that without a process to
debug.: 
Error occurred in Python: You can't do that without a process to debug.

'do that' is incredibly frustrating, gdb should state what 'that' is; I think
in most cases that might be as simple as giving noprocess() a char *reason and
passing it __func__ perhaps?

I guess the python glue could also do with saying what it was doing when it
failed.

(add meatloaf references about not saying what 'that' is as required).
