[Octave-bug-tracker] [bug #58382] Incomplete symbol info when saving variables in a script

[Markus Mützel]

Update of bug #58382 (project octave):

                Category:                     GUI => Interpreter            
                  Status:                    None => Confirmed              
                 Summary: Wrong scope when saving variables with "Run
Selection" => Incomplete symbol info when saving variables in a script

Follow-up Comment #4:

It looks like nothing needs to be done for "Run Selection" in this case.

Re-titling the bug to better reflect the underlying issue.
Comment #1 gives good instructions to reproduce.

The problem is probably with something that happens inside this function in
load-save.cc:

  size_t load_save_system::save_vars (std::ostream& os,
                                      const std::string& pattern,
                                      const load_save_format& fmt,
                                      bool save_as_floats)
  {
    tree_evaluator& tw = m_interpreter.get_evaluator ();

    symbol_info_list syminfo_list = tw.glob_symbol_info (pattern);

    size_t saved = 0;

    for (const auto& syminfo : syminfo_list)
      {
        do_save (os, syminfo, fmt, save_as_floats);

        saved++;
      }

    return saved;
  }


I don't know if a script should share its symbol info with its parent, or
something different should be done here.

Adding jwe to the CC list since I think he is the only one who has a good
understanding of the symbol info implementation.
