Timeout Timer
Add a timeout function to a function or statement and raise a exception if time limit runs out, can work as a context or decorator, support loop nesting and should use diff exception class, if use signal timer, outside timer will fired after the inside signal timer finish the work(raise exception or normal finish).
Support signal timer and thread timer, signal timer can only work on main thread, if not on main thread use thread timer, thread timer may cost longer time than time out seconds settled if the user’s function is busy in a system call (time.sleep(), socket.accept()…), exception will fired after system call done.
Usage
support nested loop
from timeout_timer import timeout, TimeoutInterrupt class TimeoutInterruptNested(TimeoutInterrupt): pass def test_timeout_nested_loop_both_timeout(timer): cnt = 0 try: with timeout(5, timer=timer): try: with timeout(2, timer=timer, exception=TimeoutInterruptNested): sleep(2) except TimeoutInterruptNested: cnt += 1 time.sleep(10) except TimeoutInterrupt: cnt += 1 assert cnt == 2
use as decorator
@timeout(2): def f(): time.sleep(3) time.sleep(2)
