[Twisted-Python] Please test Twisted 8.2.0pre2 and tell me whether it works
by Christopher Armstrong Nov. 27, 2008

Nov. 27, 2008

I just uploaded 8.2.0pre2 tarballs, which include one bugfix since 8.2.0pre1 which was deemed important enough to be backported: - TLS Session Tickets are now disabled by default, allowing connections to certain servers which hang when an empty session ticket is received (like GTalk) (#3463) The tarballs are at http://twistedmatrix.com/users/radix/8.2.0pre2/ If you want to test 8.2.0pre2 on Windows, Thomas Hervé may be able to build installers some time tomorrow. Please test … [View More]

Hi all, Twisted does not install on my windows XP /python 2.6 computer. Twisted installer says: "Python does not appear to be installed" but python is really installed and runs well on my computer ! What is the solution ? thanks Patrice -- Patrice RENAUD Observatoire de Paris - Station de Radioastronomie de Nancay Tel: 02 48 51 87 21 Fax: 02 48 51 83 18 Email: Patrice.Renaud(a)obs-nancay.fr

[Twisted-Python] Running a GUI application based on PyQt
by Nahuel Defossé Nov. 25, 2008

Nov. 25, 2008

Hi, I'm trying to use a simple application based in twisted.internet.Protocol with PyQt4. PyQt has its own way of dealing with events, I've tried to run the reactor in a thread, but it says it only can acquire SIGINT from the main thread :( I've tried the code posted in qt4reactor.py but it doesn't work. It fails telling that a reactor's been already installed. Is it possible to use PyQt4 (v.4.4) with twisted? Thanks Nahuel

[Twisted-Python] SSL Client Certificates?
by asset Nov. 25, 2008

Nov. 25, 2008

Would I be right in assuming that the example echoserv_ssl.py and echoclient_ssl.py will only result in encryption from the client to server and not from the server back to the client? Im referencing these examples specifically, http://twistedmatrix.com/projects/core/documentation/examples/echoclient_ss… http://twistedmatrix.com/projects/core/documentation/examples/echoclient_ss… From what I know of SSL, the client connects to the server, and after the handshake it uses the cert to encrypt … [View More]

by Aydın ŞEN Nov. 25, 2008

Nov. 25, 2008

Hi, I am trying to send file which is in the client's disk, i am using LineReceiver in the server side. I am sending and receiving data like login stuff but when i start to read & send file LineReceiver method doesnt run in the server side. Sending file code part is below, what can be cause of this? * i am reading 100 kb parts of file and send it, is it best choice? or reading file once and send it better? KB = 1024 * 100 while True: if (KB > file_size) | (KB … [View More]

[Twisted-Python] Blocking reactor.connectSSL()
by asset Nov. 24, 2008

Nov. 24, 2008

Is there a workaround for reactor.connectSSL() blocking during the SSL handshake? I dug around and found some indications that it could be a problem fixed in Python 2.6 and 3.0, but also that its something that is worked around in Twisted, but I havent been able to find any reference to the issue with Twisted specifically.

[Twisted-Python] TLS broken with twisted.words.protocols.jabber
by Jack Moffitt Nov. 22, 2008

Nov. 22, 2008

I would like to propose that #3463 (http://twistedmatrix.com/trac/ticket/3463) be additionally committed to the 8.1 branch and any other branches that still get point releases. It is a pretty critical workaround which fixes the fact that recent OpenSSL libraries cannot connect to Java based services. This means that most of the packaged versions of Twisted cannot talk to Google Talk or any Tigase or Openfire XMPP servers. Since packagers are often reluctant to upgrade very far in a particular … [View More]
