Limit cell execution time

[katsar0v]

Hello guys,

is there a way to limit the maximum time a cell can be executed? I am doing this currently with MappingKernelManager, but there are some side-effects. My config:

c.MappingKernelManager.cull_busy = True
c.MappingKernelManager.cull_connected = True
c.MappingKernelManager.cull_idle_timeout = 300
c.MappingKernelManager.cull_interval = 30

Side-effect 1:

• After 6 minutes, the kernel of the user is randomly culled. I know this is intended by the config.

My intention is to prevent endless loop and long code from executing, e.g.

while True:
    a = 1

It's not particularly possible natively. You could likely implement that to send a Sigint if the kernel is busy for more than x-time, but it would need to be implemented in the kernel manager.

This is likely something that you want to ask on jupyter/notebook, and not ipython/ipython.

It may also be implementable purely as a javascript extension that watch for the kernel idle and busy messages.
