[Twisted-Python] OpenID ?
by Jonathan Vanasco Nov. 9, 2006

Nov. 9, 2006

Has anyone implemented an OpenID server in twisted? I need to roll out OpenID support in my application. I'm finding a some things I don't like in the Python OpenID implementation thats out there, so I'm hoping that there might be a twisted version already? // Jonathan Vanasco | - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - | FindMeOn.com - The cure for Multiple Web Personality Disorder | Web Identity Management and 3D Social … [View More]

[Twisted-Python] PyQt4 Object acting like None.
by Nabil Nov. 7, 2006

Nov. 7, 2006

Hello everyone. I'm having some trouble with a program I'm writing. The program uses PyQt4 and qt4reactor. When the program is started it requests a file from the server that it downloads and saves onto the client machine. The file is a python module that gets dynamically loaded and used in the program. All of this works fine on a Max OS X 10.4.6 using Python 2.4.4 and Qt-4.1.0. When I try to run the program on window I get this error message: File "C:\path\to\downloaded\module", … [View More]

[Twisted-Python] DeferredQueue Unstable
by Sean Roark Nov. 7, 2006

Nov. 7, 2006

The API says the DeferredQueue class from the defer module is unstable? Any description about why it is unstable? I would like to use it else I will have to write my own version that is sure to 'unstable'. -- Sean Roark

[Twisted-Python] Twisted and Torrent Support
by Chas. Nov. 6, 2006

Nov. 6, 2006

I am looking for both client and server support for bittorrent that is integrated with Twisted (as are the ftp, etc). I was wondering if any one knows of just such support. Thanks, Chaz.

[Twisted-Python] Problem with qt4reactor.py
by IloChab Nov. 6, 2006

Nov. 6, 2006

I'm trying to run a simple application with Twisted and Qt4, but I get a really strange behavior from my main script. I can't understand if it's a python or a twisted or a Qt4 problem I'm using this reactor: http://twistedmatrix.com/trac/attachment/ticket/1770/qt4reactor.py Now, if I run this: # >>>>>>>>> import qt4reactor import sys from PyQt4 import QtGui from winIum import Window def main(): app = QtGui.QApplication(sys.argv) qt4reactor.install(… [View More]

[Twisted-Python] If lineReceived returns deferred, then connection is dropped and this deferred given as error message
by Marcin Kasperski Nov. 6, 2006

Nov. 6, 2006

I am observing the twisted behaviour which seems rather strange to me. In short: if lineReceived returns some deferred, then the whole connection is aborted, moreover, this deferred is returned as error message. Longer story (the code pieces extracted from quite large app, I have not yet tried writing small example) ### Crucial code fragments class SomeProtocol(basic.LineReceiver): (...) def lineReceived(self, line): (...) return defer.succeed(997) # magic value I can recognize … [View More]

[Twisted-Python] SMTP with authentication
by Alvin Wang Nov. 5, 2006

Nov. 5, 2006

Hi, I am new to twisted but google and the Oreilly book have failed me. I am trying to create a client to send to a smtp server. All the examples that I have found only work if your SMTP server does not require authentication. I am guessing that I need to use http://twistedmatrix.com/documents/current/api/twisted.mail.smtp.ESMTPSende… Unfortunately, I can find no examples that use it. I did find something from 2004 http://twistedmatrix.com/pipermail/twisted-python/2004-April/007433.html… [View More]

Thanks Thomas, indeed I mentioned the wrong ticket number, my mistake, I'm already getting flogged for that ;-) I'd be glad to get your FTP access class.

That's what I don't understand. You were mentioning a different ticket number... Anyway, you seem to be waiting for the first storeFile deferred (Consumer) to indicate successful transmission, I'm using the second (Control-Connection), maybe you simply quit to early. If you want, I can mail you my FTP access class for uploading and downloading.... > Stéphane > > > ----- Message d'origine ---- > De : Thomas Jacob <jacob(a)internet24.de> > À : Twisted general discussion <twisted-python(a)twistedmatrix.com> > Envoyé le : Vendredi, 3 Novembre 2006, 10h32mn 52s > Objet : Re: [Twisted-Python] Problem with ftp upload > > There is bug in storeFile's Consumer interface > (Cf. report + patch http://twistedmatrix.com/trac/ticket/1794 ) > > As for disconnecting, why not call ftpClient->quit() after > your upload has finished? > > On Thu, 2006-11-02 at 20:57 +0000, Stéphane Brault wrote: > > Hi, > > > > I'm using twisted ftp api to upload files, I also added the ticket 1914 patch. > > Here is my code : > > class myFTP(object): > > > > def __init__(self, login, password): > > self.creator = ClientCreator(reactor, FTPClient, login, password, passive=0) > > > > > > def connectionFailed(self, f): > > print 'connection error' > > > > > > def success(self, response): > > print 'Success' > > > > > > def fail(self, error): > > print 'Erreur:' + error > > > > > > def doOperation(self, operation, data): > > d = self.creator.connectTCP(FTP_ADDRESS, 21) > > if operation == 'addItems': > > return d.addCallback(self.inventoryUpload, data).addErrback(self.connectionFailed) > > elif .... > > > > > > > > def _upload(self, consumer, file): > > return FileSender().beginFileTransfer(file, consumer).addCallback(lambda _: consumer.finish()).addCallback(lambda _: file.close()) > > > > > > def inventoryUpload(self, ftpClient, file): > > name = '/stock/entrees/export_items_' + encodeDate(datetime.datetime.now()) + '.txt' > > return ftpClient.storeFile(name)[0].addCallback(self._upload, file).addCallbacks(self.success, self.fail) > > > > .... > > > > The operation is called this way: > > call = myFTP(login, password) > > call.doOperation('addItems', StringIO(data)) > > > > The file is created but empty, it seems that _upload is not called, I can't understand why, any hint ? > > I was also wondering how to disconnect once my work is done, I don't think keeping open connections is a good thing. > > > > Thanks, > > > > Stéphane > > > > > > > > > > > > > > > > > > ___________________________________________________________________________ > > Découvrez une nouvelle façon d'obtenir des réponses à toutes vos questions ! > > Profitez des connaissances, des opinions et des expériences des internautes sur Yahoo!

Thanks Thomas, my problem is that I already applied the patch and it still doesn't work. That's what I don't understand.
