[Octave-bug-tracker] [bug #54600] edit mfile with an error crashes octave

[Pantxo Diribarne]

Follow-up Comment #8, bug #54600 (project octave):

I think it would be interesting to know if in Matlab "which fcn" leads to an
error when "fcn" happens to not be executable. Personally, what I want when I
use "which fcn" is Octave to answer the question "In which file will you
search for the definition of fcn?". So I would be inclined to change
F__which__ behavior, which would fix this bug.

@Torsten: About comment #4, if you really want an error that doesn't crash the
GUI, you can use a try/catch and rethrow the error as we do when printing:


try
  {
    // Make sure we have a valid current context
    if (! begin_rendering ())
      error ("print: no valid OpenGL offscreen context");
 
    octave::gl2ps_print (figObj, file_cmd.toStdString (),
                                  term.toStdString ());
  }
catch (octave::execution_exception& e)
  {
    octave_link::post_exception (std::current_exception ());
    end_rendering ();
  }
