So summary:

mtasaka commented 1 week ago

Then at some time, cd_rendering_calculate_max_dock_size_3D_plane is again called, then pDock->iDecorationsHeight is updated, then cd_rendering_render_3D_plane gets working finally.

But anyway I think causing zero division, then causing nan operation is unpleasant, so ideally functions should be called in order:

But currently I have no idea how to fix so.

Hi,

thank you for reporting and the detailed analysis! I agree that the config file should be read before any of the other functions. I do have an idea how to do that, but I'll need some time to experiment with it. If you need a quick workaround, setting any sensible default value for the problematic parameters should work. E.g. probably the following (not tested):

Hi,

I've come up with a potential solution, it is available here: https://github.com/dkondor/cairo-dock-core/tree/module_autoload_config (note: it is a change in the core of CD, which you need to recompile using that branch; no changes needed for the plugins)

I'm not yet sure if I'm completely happy with this solution, but would be great if you could test and give feedback. Thank you!

mtasaka commented 1 day ago

For me, the above branch (module_autoload_config) seems to be working, thank you.

dkondor commented 1 day ago

Great, thank you for testing! I'll review it one more time and then merge it
