示例1: wait_impl
# 需要导入模块: import os [as 别名]
# 或者: from os import wait3 [as 别名]
def wait_impl(self, cpid):
# This many iterations can be required, since some previously run
# tests (e.g. test_ctypes) could have spawned a lot of children
# very quickly.
deadline = time.monotonic() + 10.0
while time.monotonic() <= deadline:
# wait3() shouldn't hang, but some of the buildbots seem to hang
# in the forking tests. This is an attempt to fix the problem.
spid, status, rusage = os.wait3(os.WNOHANG)
if spid == cpid:
break
time.sleep(0.1)
self.assertEqual(spid, cpid)
self.assertEqual(status, 0, "cause = %d, exit = %d" % (status&0xff, status>>8))
self.assertTrue(rusage) 示例2: wait_impl
# 需要导入模块: import os [as 别名]
# 或者: from os import wait3 [as 别名]
