示例1: _kill
# 需要导入模块: from psutil import Process [as 别名]
# 或者: from psutil.Process import send_signal [as 别名]
def _kill(pid, timeout=1.5):
try:
process = Process(pid)
except NoSuchProcess:
return
try:
process.send_signal(SIGINT)
sleep(timeout)
except OSError:
pass
finally:
try:
process.send_signal(SIGKILL)
except (OSError, NoSuchProcess):
pass
process.wait()示例2: test_sigint
# 需要导入模块: from psutil import Process [as 别名]
# 或者: from psutil.Process import send_signal [as 别名]
def test_sigint(self):
'''
Setup test server sleep 0.01 for each request
Start spider in separate python shell (untill sigin
or max 200 requests)
Wait 1 sec (~100 requests, in reality less
because of process start-up time)
Send SIGINT to the process
Check it returned with 13 or 139 codes
139 code means segfault (yeah...o_O) But as I see from logs
it segfaults after successfully processing the SIGINT and
this is all I need from this test
