[Twisted-Python] Throttling Factory Problem ...
by Joël Vennin July 20, 2003

July 20, 2003

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello all, I'm making an example to limit bandwidth with ThrottlingFactory. I've a server and a client. Client and server make echo. So it's an infinite process. I've limited the bandwith to 1Ko/s. The problem is that the client send a lot's of data (more than the limited bandwidth) during a little time. The server get all the data (more than the limited bandwith) and after each wait a long of time before send/received something. Maybe i … [View More]

[Twisted-Python] help, my woven web app won't work on win32 but will on linux!
by Oisin Mulvihill July 20, 2003

Hi, I've produced a small model of my program which hightlights the problem I'm having. Attached are two files main.py and index.rpy. To run the web app run main and make sure index.rpy is in the same directory. Then point your web browser to http://localhost:20808 On linux I can click on the web buttons and the app works fine. One windows (I'm using win2k) I simply get "No Such Resource, File not found". The button press issues a post and this shows up as the url "http://localhost:20808/… [View More]

[Twisted-Python] htp example and twisted CPU usage
by Joël Vennin July 20, 2003

July 20, 2003

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello all, I'm making an application with twisted and i have some problem with it. I need to be able to limit bandwidth for a group of connection. A group of connection can be "incoming client" (client connect to the server) and/or "outcoming client" (server connect to the client). Another request is to limit the "global bandwidth" upload and download. I've take a look at the htb module in twisted.protocols but i'm not convinced about … [View More]

[Twisted-Python] Accessing app-wide data in Woven
by mesozoic July 18, 2003

July 18, 2003

I am writing a Woven app that I would like to make fairly configurable by the end-user without asking them to change my code. The way I'm doing this now is with a special class, SiteConfiguration, that is given various data in the root-level .rpy. Now, every Page, every Model, and every View should (in my perfect world) be able to get at this class. There should be only one SiteConfiguration; I'd like to avoid calling it "global", because I know that word means many different things. So what I … [View More]

[Twisted-Python] Simplifying my StatusMonitor
by Brad Bollenbach July 18, 2003

July 18, 2003

Hi, Okay, in the usual XP fashion, I'm doing a spike to assess two use cases for Twisted: 1. Writing a simple monitor that checks the status of a response, to see what it's like to write a foobar in Twisted. 2. How to schedule multiple monitor batches so they can run and report back to a "central command" (maybe CentralCommand or something), which can then determine whether or not (and to whom) an error report should be sent. (I've scrapped the idea of a "monicron") I did #1 this morning. … [View More]

[Twisted-Python] Woven LivePage sendScript works with some scripts but not others
by Tim Andrews July 18, 2003

July 18, 2003

Hi twisted, I'm trying to use LivePage to send some script to a web page. All works well if the script is as per the manual example, ie sendScript("alert('Hello world!')") will pop up a window as expected. However, if i try a script like "document.all.fred.innerHTML='FRED'" I get an error on the page "Error: document.all.fred is null or not an object". I know the script is okay because if it is on the on the page it will work. Any clues? Thanks, Tim Some example code for your perusal ...… [View More]

I'm also interested in using Rendezvous in twisted. I don't have much time at the present to both learn Rendezvous and the internals of twisted but I'll pass on two links if you haven't seen them. The first link is http://dotlocal.org/ and they are "Software developers interested in implementing zeroconf, multicast dns and dns service discovery". The second link is a Python implementation of Rendezvous, PyRendezvous, which can be found at.. http://radio.weblogs.com/0105002/stories/2003/01/06/multicastDnsServiceDisc…

[Twisted-Python] How Twisted is This?
by Brad Bollenbach July 17, 2003

July 17, 2003

Hi, I'm evaluating Twisted for the networking component of a web server monitoring service. Eventually, this service will support monitoring pretty much any TCP-enabled device. I want to figure out whether Twisted is applicable to my problem. This web monitoring system will be: * branded for the company I work for * multiuser * offer various ways of verifying the uptime and integrity of content on a site: i. Can I open an HTTP connection to this site? ii. Is "foo bar" present … [View More]

[Twisted-Python] with a subject this time - Woven LivePage beginners trouble
by Tim Andrews July 16, 2003

July 16, 2003

Hi twisted, I've just started playing with twisted and am keen to get something happening with LivePage. I can serve pages quite happily from an .rpy and have tried to follow the examples from the manual to get event handlers and LivePage happening. When my page is generated "MyController.handle" gets called, but "MyController.setUp" never gets called. If I add an "__init__" method it gets called, but when I try to call "self.view.addEventHandler" it complains that self.view is a NoneType. … [View More]I have also tried subclassing input.Anything, but suffer from a similar problem in that my "initialize" method never gets called or if I call "input.Anything.__init__" then I still have a problem with "self.view.addEventHandler" FYI I'm running twisted 1.06 on Python 2.2 on a Windows 2000 box My code for your perusal ... from twisted.web.woven import page, controller model = { 'name': 'fred', 'stuff': ['Foo', 'Bar', 'Baz'] } template = """ <html> <body> <h3 model="name" view="Text" controller = "foo"/> <div model="stuff" view="List"> <li pattern="listItem" view="Text"/> </div> <span view="webConduitGlue" /> </body> </html> """ class MyController(controller.Controller): # def __init__(self, *args, **kwargs): # controller.Controller.__init__(self, args, kwargs) # self.view.addEventHandler("onmouseover", self.mouse) # self.view = NoneType :( def setUp(self, request, *args): print "setUp" # this never happens :( def handle(self, request): print 'handle' # this happens :) def mouse(self, request, widget): print 'Mouse Over!!!' class MyPage(page.LivePage): def wcfactory_foo(self, request, node, model): print 'foo factory' # this happens :) return MyController(model) resource = MyPage(model, template=template) Thanks, Tim PS sorry about the finger trouble ---------------------------------------- Tim Andrews Principal Hardware Engineer Vision Fire and Security 14 Park Way, Technology Park Mawson Lakes, S.A. 5095 ph: +61-8-84621201 fax: +61-8-84621001 email: Tim.Andrews(a)adpro.com.au web site: www.adpro.com.au ---------------------------------------- IMPORTANT ?
