web_pdb hangs at page load

[vadimkantorov]

Apparently because of server hangs at some variable formatting:

I waited a few dozen seconds and then hit Ctrl+C and got somehow this stack trace:

  File "/usr/lib/python3.10/bdb.py", line 90, in trace_dispatch
    return self.dispatch_line(frame)
  File "/usr/lib/python3.10/bdb.py", line 114, in dispatch_line
    self.user_line(frame)
  File "/usr/lib/python3.10/pdb.py", line 253, in user_line
    self.interaction(frame, None)
  File "/usr/lib/python3.10/pdb.py", line 348, in interaction
    self._cmdloop()
  File "/usr/lib/python3.10/pdb.py", line 317, in _cmdloop
    self.message('--KeyboardInterrupt--')
  File "/usr/lib/python3.10/pdb.py", line 448, in message
    print(msg, file=self.stdout)
  File "/home/vadimkantorov/.local/lib/python3.10/site-packages/web_pdb/web_console.py", line 152, in writeline
    frame_data = self._debugger.get_current_frame_data()
  File "/home/vadimkantorov/.local/lib/python3.10/site-packages/web_pdb/__init__.py", line 174, in get_current_frame_data
    'locals': self.get_locals()
  File "/home/vadimkantorov/.local/lib/python3.10/site-packages/web_pdb/__init__.py", line 214, in get_locals
    return self._format_variables(self.curframe_locals)
  File "/home/vadimkantorov/.local/lib/python3.10/site-packages/web_pdb/__init__.py", line 189, in _format_variables
    return '\n'.join(sorted(f_vars))
KeyboardInterrupt

Maybe some variables are super-huge strings, and it tries to format them and thus hanging?

It's hard to tell anything without an example of code that causes such issue.
