The program keeps dying, but I can't find where it dies. How do I signal my Python interpreter to find out which code it runs?
python debugging stack-trace traceback
Usually, it runs well, but sometimes the program ends for some reason I'll tell you the method I used then. It's a code that I personally made, so it's not universal, but it can only be used in a unix environment.
import code, traceback, signal
def debug(sig, frame):
"""Interrupt running process, and provide a python prompt for
interactive debugging."""
d={'_frame':frame} # Allow access to frame object.
d.update(frame.f_globals) # Unless shadowed by global
d.update(frame.f_locals)
i = code.InteractiveConsole(d)
message = "Signal received : entering python shell.\nTraceback:\n"
message += ''.join(traceback.format_stack(frame))
i.interact(message)
def listen():
signal.signal(signal.SIGUSR1, debug) # Register handler
When writing, you must call the listen() function at the beginning of the program.
os.kill(pid, signal.If you send a ,
Python console stops and shows stack trace results.SIGUSR1 signal using kill, like SIGUSR1)
Press ctrl-d(EOF) to continue running on stack trace.
