Can't debug an infinite loop using run-by-line (can't interrupt kernel after disconnecting run-by-line debugger) #11187

What happened?

Created a cell with infinite loop

def f():
    i = 0
    while i < float('inf'):
        i+= 1

Add a breakpoint to the first cell

Created another cell which calls into that cell

print(f())

Debug the second cell

You are now debugging and able to step through. Debug toolbar is visible.

The debug toolbar doesn't show the stop icon, only disconnect.

If you disconnect then the cell just executes forever, debug toolbar disappears and the Interrupt button is disabled. Only option left is restarting the kernel in the notebook toolbar.

As for the restart button in the debug toolbar, it does something but I have no idea what. I think it's disconnecting and then reconnecting the debug session, but the code has just kept executing.

roblourens commented 2 years ago

I'll have to look into why that toolbar button is disabled. It seems that the stop button on the cell (where the run button normally is) is enabled and works fine when debugging.

GF-Huang commented 2 years ago

Same issue, after disconnect debug, interrupt button disabled, I can't interrupt it.

roblourens commented 2 years ago

Seems fixed now
