From: Ben Darnell Date: Sun, 19 Aug 2012 05:56:14 +0000 (-0700) Subject: Reorganize IOStream tests and run them in both regular and ssl mode. X-Git-Tag: v2.4.0~23 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=0147ac24d771f05e6850ecb14c4fbd57f4b33597;p=thirdparty%2Ftornado.git Reorganize IOStream tests and run them in both regular and ssl mode. In the process, discover a quirk of the server-side SSL handshake and a possible bug with ssl in pypy. --- diff --git a/tornado/test/iostream_test.py b/tornado/test/iostream_test.py index 99d6add2f..0f267b854 100644 --- a/tornado/test/iostream_test.py +++ b/tornado/test/iostream_test.py @@ -1,53 +1,61 @@ from __future__ import absolute_import, division, with_statement from tornado import netutil from tornado.ioloop import IOLoop -from tornado.iostream import IOStream -from tornado.testing import AsyncHTTPTestCase, LogTrapTestCase, get_unused_port +from tornado.iostream import IOStream, SSLIOStream +from tornado.testing import AsyncHTTPTestCase, AsyncHTTPSTestCase, AsyncTestCase, LogTrapTestCase, get_unused_port from tornado.util import b from tornado.web import RequestHandler, Application import errno +import os +import platform import socket import sys import time +try: + import ssl +except ImportError: + ssl = None + class HelloHandler(RequestHandler): def get(self): self.write("Hello") -class TestIOStream(AsyncHTTPTestCase, LogTrapTestCase): +class TestIOStreamWebMixin(object): + def _make_client_iostream(self): + raise NotImplementedError() + def get_app(self): return Application([('/', HelloHandler)]) - def make_iostream_pair(self, **kwargs): - port = get_unused_port() - [listener] = netutil.bind_sockets(port, '127.0.0.1', - family=socket.AF_INET) - streams = [None, None] + def test_connection_closed(self): + # When a server sends a response and then closes the connection, + # the client must be allowed to read the data before the IOStream + # closes itself.
