Here is my function definition: @defer.inlineCallbacks def get_order(order_id): # do some db operations... defer.returnValue(order_details) What I want to do is to test this function using Twisted's trial: from twisted.trial import unittest from twisted.internet import defer class OrderTest(unittest.TestCase): @defer.inlineCallbacks def test_order(self): order = yield get_order(5) raise Exception('FAIL FAIL!!') # this should fail, but never does self.assertEqual(order.id, 6) I'm very confused.. I red all the documents that I could find about Twisted and trial but couldn't find how to make this

I am in a weird situation where I have to use Twisted in a system built completely out of Tornado. They can share the same IOLoop so I know they can work together. My question is can I safely use their co-routine decorators in the same function? For example: import tornado.platform.twisted tornado.platform.twisted.install() ... @gen.engine @defer.inlineCallbacks def get(self): ... a = yield gen.Task(getA) # tornado b = yield proxy.callRemote(getB) # twisted ... defer.returnValue(a + b) # twisted They do work on the same IOLoop so I am thinking this should be fine. Would there be any unforeseen

This is related to the previously answered question here: Logging SMTP connections with Twisted . I have a database resource that I create in each instance of ConsoleMessageDelivery that I need to ensure is cleaned up when the socket is closed. I have a WrappingFactory called DenyFactory and the DenyFactory.unregisterProtocol method is called when the socket is closed, but I have no way (that I can figure out) how to access the resource created in the ConsoleMessageDelivery instance that's being destroyed. I tried a del () method in ConsoleMessageDelivery but that's never called. What's the

I'm trying to develop a Twisted Web server but can't seem to run the twistd command. I've tried setting the python path and even included the path to the twistd.py script in my Path but nothing seems to work. I'm using Twisted 12.0.0 and Python 2.7 on Windows. Any help would be hugely appreciated. You need to set the %PATHEXT% environment variable to include .py , as well as %PATH% including the path to twistd . Your most-recently-installed version of Python should then automatically launch it, assuming the filetype association was set correctly by the installer. Create a twistd.bat and save

I wrote my very first Twisted 10.1.0 web Resource and I am seeking for feedback, because I feel this isn't exactly following the best practice and may contain newbies bugs. The resource responds to /?url=http://www.foo.baz/abc123 and relies on a service that returns a dict . If anything goes wrong (e.g., invalid or non-existing url , then a 400 is returned). Any comment? Anything to fix, to improve class ProcessedUrl(resource.Resource): isLeaf = True def __init__(self, service): resource.Resource.__init__(self) self.service = service def _cancel(self, err, deferred): deferred.cancel() def

I'm using Twisted 11 together with SQLAnywhere 12 via the official sqlanydb driver. Generally, it works fine. But occasionally the application crashes with an abort on the first query. If one query worked, all following work too. However my tests run only seldom through. That's awful to develop with and strace doesn't tell me anything informative too. Sometimes it crashes inside of select(), sometimes in mmap()... I'm running 64bit Linux and run locally the Sybase as dbeng12 for testing. Is anyone working successfully using these components? Any suggestions how to solve that? I used sqlanydb
