Getting protocol folder size can be problematic

[delarosatrevin]

In running protocols where some tmp folders/files are deleted, it can raise the following exception:

Exception in Tkinter callback

    return os.stat(filename).st_size

Moreover, for some large datasets (e.g. tens of thousands of movies) this can take a long time to compute and freeze the whole GUI.

I propose to either avoid that computation or have some sort of cache value that prevents from running that many IO queries every time one hover over a protocol box.

I think it is cached . But I. This case it can't even cache it. We shoul tolerate errors there. El jue., 7 dic. 2023 21:13, Jose Miguel de la Rosa Trevin < ***@***.***> escribió:

Apart from being cached, might be a good idea to do the updated in a background thread. This will prevent blocking the GUI, even in the case where the size needs to be re-calculated.
