zsh: segmentation fault python Datamosher\ Pro.py

[alexauvray]

Happens when I click on "Mosh" from the GUI.

WarpAI thinks the issue comes from this:

Perfect! Now we have the exact location of the segfault. The issue is in the tkinter configuration in a threading context, specifically in line 792 in the do_the_mosh function. The segfault occurs when a customtkinter button is being configured from within a thread, which is calling tkinter's _configure method.

This is a classic threading issue with tkinter - tkinter is not thread-safe, and GUI operations must only be performed from the main thread.

I found the issue. The problem is that the do_the_mosh() function is being called from a background thread (started in line 779 with threading.Thread(target=do_the_mosh).start()), but this function contains multiple GUI operations that are not thread-safe:

•  Line 792: button_mosh.configure(state=tkinter.DISABLED)  ⬅️ This is line 792 where the crash occurs
•  Line 793: button_open.configure(state=tkinter.DISABLED)
•  Multiple ProcessLabel.configure() calls
•  Various messagebox calls
•  And many other GUI operations throughout the function

The solution is to modify the code so that GUI operations are performed in the main thread using root.after() or similar mechanisms.
