Interruptingcow is a generic utility can relatively gracefully interrupt your Python code when it doesn't execute within a specific number of seconds:
from interruptingcow import interruptingcow, InterruptedException try: with interruptingcow(timeout=5): # perform a potentially very slow operation pass except InterruptedException: print "didn't finish within 5 seconds"
$ pip install interruptingcow
Interruptingcow uses signal(SIGALRM) to let the operating system interrupt program execution. This has the following limitations:
- SIGALRM is not reentrant so you can not nest timeouts
- Python signal handlers only apply to the main thread, so you cannot use this from other threads
- You must not use this in a program that uses SIGALRM itself
