Broken: 2.80, latest 2.8 Git branch
Worked: 2.79b release
Short description of error
In Blender 2.8 it's not possible anymore to override the space_time.py file.
Exact steps for others to reproduce the error
Move on any button of the panel header (timeline) and edit source to open the space_time.py.
Any changes made on the file are not visible.
I can edit space_time.py and the changes are visible on the next startup.
Do you mean that the changes are not saved to the space_time.py file for you?
I mean changes are not visible live. At startup yes, it works.
While digging into it I discovered the python override has other bugs.
If you try, for example to override the text in the render sampling, and hit run script, it's going to fail because it doesn't find
from .space_view3d import (
VIEW3D_PT_shading_lighting,
VIEW3D_PT_shading_color,
VIEW3D_PT_shading_options,
)Changing it to:
from bl_ui.space_view3d import (
VIEW3D_PT_shading_lighting,
VIEW3D_PT_shading_color,
VIEW3D_PT_shading_options,
)works and the change is visible live (after clicking run script) but get anyway another error:
RuntimeError: Error: Registering panel class: parent 'RENDER_PT_eevee_volumetric' for 'RENDER_PT_eevee_volumetric_shadows' not found
I guess this bug report title should be changed to something more generic as this issue happens (almost) everywhere with Blender 2.8
I have re-triaged this report and can not reproduce it. Assuming, that issue was, that after running Reload Scripts operator, UI wasn't updated.
Can you please check if this is still an issue in latest build?

The issue with space_time.py is unavoidable, as these functions are called indirectly. The second issue you mention here: T61448#619916 has been resolved.
