timeout-decorator 0.4.0

Installation

From source code:

python setup.py install

From pypi:

pip install timeout-decorator

Usage

import time
import timeout_decorator

@timeout_decorator.timeout(5)
def mytest():
    print "Start"
    for i in range(1,10):
        time.sleep(1)
        print "%d seconds have passed" % i

if __name__ == '__main__':
    mytest()

Specify an alternate exception to raise on timeout:

import time
import timeout_decorator

@timeout_decorator.timeout(5, timeout_exception=StopIteration)
def mytest():
    print "Start"
    for i in range(1,10):
        time.sleep(1)
        print "%d seconds have passed" % i

if __name__ == '__main__':
    mytest()

Multithreading

By default, timeout-decorator uses signals to limit the execution time of the given function. This appoach does not work if your function is executed not in a main thread (for example if it’s a worker thread of the web application). There is alternative timeout strategy for this case - by using multiprocessing. To use it, just pass use_signals=False to the timeout decorator function:

import time
import timeout_decorator

@timeout_decorator.timeout(5, use_signals=False)
def mytest():
    print "Start"
    for i in range(1,10):
        time.sleep(1)
        print "%d seconds have passed" % i

if __name__ == '__main__':
    mytest()
