示例1: test_final_callback_stack_context
# 需要导入模块: from tornado.ioloop import IOLoop [as 别名]
# 或者: from tornado.ioloop.IOLoop import handle_callback_exception [as 别名]
def test_final_callback_stack_context(self):
# The final callback should be run outside of the httpclient's
# stack_context. We want to ensure that there is not stack_context
# between the user's callback and the IOLoop, so monkey-patch
# IOLoop.handle_callback_exception and disable the test harness's
# context with a NullContext.
# Note that this does not apply to secondary callbacks (header
# and streaming_callback), as errors there must be seen as errors
# by the http client so it can clean up the connection.
