示例1: install_signal_handlers

# 或者: from gevent import signal_handler [as 别名]

else:

self.shutdown_graceful()
# First time CTRL-C, try to shutdown gracefully
gevent.signal_handler(signal.SIGINT, request_shutdown_graceful)
# User (or Heroku) requests a stop now, just mark tasks as interrupted.
gevent.signal_handler(signal.SIGTERM, request_shutdown_now) 示例2: __init__

gevent.signal_handler(signal.SIGTERM, sig_term_handler) 示例3: test_orphaned_signal_watcher
# 需要导入模块: import gevent [as 别名]
# 或者: from gevent import signal_handler [as 别名]
def test_orphaned_signal_watcher(self):
# Install libev-based signal watcher.
try:
s = gevent.signal(signal.SIGTERM, signals_test_sigterm_handler)
except AttributeError:
# This function got renamed in gevent 1.5
s = gevent.signal_handler(signal.SIGTERM, signals_test_sigterm_handler)
# Normal behavior: signal handlers become inherited by children.
# Bogus behavior of libev-based signal watchers in child process:
# They should not be active anymore when 'orphaned' (when their
# corresponding event loop has been destroyed). What happens, however:
# The old handler stays active and registering a new handler does not
# 'overwrite' the old one -- both are active.
# Since this test is about testing the behavior of 'orphaned' libev
# signal watchers, the signal must be transmitted *after* event loop
# recreation, so wait here for the child process to go through
# the hub & event loop destruction (and recreation) process before
# sending the signal. Waiting is realized with sync through pipe.
# Without cleanup code in gipc, the inherited but orphaned libev signal
# watcher would be active in the fresh event loop and trigger the
# handler. This is a problem. With cleanup code, this handler must
# never be called. Child exitcode 20 means that the inherited handler
# has been called, -15 (-signal.SIGTERM) means that the child was
# actually killed by SIGTERM within a certain short time interval.
# Returncode 0 would mean that the child finished normally after that
# short time interval.
