AttributeError: 'GraphDisplay' object has no attribute 'sizing'

[p1r473]

Hi, one of the widgets is throwing errors.
Heres what I see:

   canv = self._original_widget.render(size, focus=focus)
           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "/usr/local/lib/python3.11/dist-packages/urwid/widget/widget.py", line 112, in cached_render
    canv = fn(self, size, focus=focus)
           ^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "/usr/local/lib/python3.11/dist-packages/urwid/widget/columns.py", line 926, in render
    widths, _, size_args = self.get_column_sizes(size, focus)
                           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "/usr/local/lib/python3.11/dist-packages/urwid/widget/columns.py", line 857, in get_column_sizes
    w_sizing = widget.sizing()
               ^^^^^^^^^^^^^^^
  File "/usr/local/lib/python3.11/dist-packages/urwid/widget/pile.py", line 103, in sizing
    w_sizing = widget.sizing()
               ^^^^^^^^^^^^^

I think its the speedometer

This issue has been resolved in commit 114ebb71a83ea3e3c7a9df8b4e4f9f89e1c7b0c3.

Root Cause

The speedometer utility has a compatibility issue with urwid 2.4.0+. Speedometer's SpeedGraph class doesn't properly inherit from urwid.Widget, which causes it to lack the sizing() method that urwid 2.4+ requires.

Upstream Issue: wardi/speedometer#30
Upstream Fix (not yet merged): wardi/speedometer#31

Hollywood's Solution

Instead of crashing when speedometer fails, hollywood now:

1. Tests speedometer before the main loop to detect compatibility issues
2. Displays a helpful message if speedometer fails:

   Speedometer unavailable (urwid compatibility issue)
   
   This may be due to incompatible urwid version (2.4.0+)
   See: https://github.com/wardi/speedometer/issues/30
   
   Workarounds:
     - Downgrade urwid: pip3 install 'urwid<2.4.0'
     - Or wait for speedometer upstream fix
   

3. Prevents crash loops - exits gracefully if speedometer crashes during runtime
4. Keeps hollywood running - other panes continue to function normally

Workarounds for Users

Option 1: Downgrade urwid (temporary fix)

pip3 install 'urwid<2.4.0'

Option 2: Wait for upstream

• The speedometer maintainer needs to merge PR mi.mp4 File not found #31
• Once merged, updating speedometer will fix the issue

Option 3: Use hollywood without speedometer

• Hollywood will now gracefully skip the speedometer pane
• All other widgets continue to work normally

This fix will be included in the upcoming 1.25 release. Hollywood now fails gracefully instead of crashing when speedometer has compatibility issues.
