Unexpected type ’float’ with Python 3.10

[mdinslage]

Distro: Slackware 15 RC1

Version: Openrazer 3.1.0

Version: Polychromatic 0.7.0

Today Slackware upgraded its Python3 to version 3.10. After rebuilding openrazer and all the required dependencies for both it and polychromatic I am getting the following error

Eeks! An uncaught exception was thrown while loading the tab.

Traceback (most recent call last):
  File ’/usr/share/polychromatic/../../bin/polychromatic-controller’, line 380, in _change_tab
    tab_objects[index].set_tab()
  File ’/usr/lib64/python3.10/site-packages/polychromatic/controller/devices.py’, line 136, in set_tab
    self.open_device(first_item.backend, first_item.uid)
  File ’/usr/lib64/python3.10/site-packages/polychromatic/controller/devices.py’, line 244, in open_device
    widgets.append(self._create_row_control(device, zone, option))
  File ’/usr/lib64/python3.10/site-packages/polychromatic/controller/devices.py’, line 311, in _create_row_control
    return self.widgets.create_row_widget(option_label, self._create_control_slider(device, zone, option))
  File ’/usr/lib64/python3.10/site-packages/polychromatic/controller/devices.py’, line 342, in _create_control_slider
    slider.setTickInterval(option[’max’] / 10)
TypeError: setTickInterval(self, int): argument 1 has unexpected type ’float’

Polychromatic does launch, but is mostly unusable to to this error. I am assuming this is somehow related to Python 3.10 since it broke right after Slackware added it. I have been rebuilding many packages because of it.

If anyone has any ideas please let me know.
Thanks

I can confirm it's an issue with our code, sorry! I haven't seen this deprecation notice until now, after testing PyQt5 code in a Python 3.9 interpreter:

DeprecationWarning: an integer is required (got type float). Implicit conversion to integers using int is deprecated, and may be removed in a future version of Python.

The temporary fix would be to make amends to /usr/lib64/python3.10/site-packages/polychromatic/controller/devices.py on line 342.

-slider.setTickInterval(option["max"] / 10)
+slider.setTickInterval(int(option["max"] / 10))

This is a bit awkward since I have a huge refactor in progress, and this bug will affect other rolling release distros soon, so I'll need to act swiftly.

No apology necessary. Things happen on the bleeding edge. And yes, Slackware is pretty much a rolling release right now, much to the frustration of many Slackware users, myself included. Usually when Slackware hits RC stage a upgrade like Python 3.9 to 3.10 wouldn't happen, but I guess Patrick Volkerding has his reasons. Anyway, the temporary fix above works.

Thanks.
