[Twisted-Python] pyserial on Python3
by Adi Roiban 08 Nov '15

08 Nov '15

Hi, We have this ticket which ports twisted.internet.serialport on Python 3 - https://twistedmatrix.com/trac/ticket/8099 I saw that the Python 3 builders don't have pyserial installed. Was this on purpose or just forgetting to also install .[all_non_platform] on the python 3 builders? Thanks! -- Adi Roiban

[Twisted-Python] The End of Windows XP Support in Twisted 15.5
by Amber "Hawkie" Brown 07 Nov '15

07 Nov '15

Hi everyone, We've just removed the Windows XP builder from our buildbot. Many thanks for Tom Prince for keeping it online for so long, but right now, we think it's time to retire targeting XP. Our only current supported Windows platform is Windows 7 x64, with Python 2.7.10, with Python 3.4 and Python 3.5 support coming soon. - Amber

[Twisted-Python] Specification / RFC of the twisted.conch.ssh.keys.Key.privateBlob implementation
by Adi Roiban 04 Nov '15

04 Nov '15

Hi, Does anyone know what specifications / RFC is used for implementing twisted.conch.ssh.keys.Key.privateBlob ? https://github.com/twisted/twisted/blob/trunk/twisted/conch/ssh/keys.py#L577 I could not find the over-the-wire format for private keys... as I supposed that private keys should not be put on the wire, in the first place. I did find a SSH agent draft https://tools.ietf.org/html/draft-ietf-secsh-agent-02#section-1.4.1 but the format is different than the one from the docstring. In twisted privateBlob is only used to support twisted.conch.ssh.agent Is anyone using this method ? Thanks! -- Adi Roiban

[Twisted-Python] How to call a Twisted reactor from a file different from his module?
by Samuel Góngora García 04 Nov '15

04 Nov '15

I have a question that could well belong to Twisted or could be directly related to Python. My problem, as the other is related to the disconnection process in Twisted. As I read on this , if I want to I have to perform the following steps: 1-The server must stop listening. 2-The client connection must disconnect. 3-The server connection must disconnect. According to what I read on the previous page to make the first step would have to run the stopListening method. In the example mentioned in the web all actions are performed in the same script. Making it easy to access the different variables and methods. For me I have a server and a client are in different files and different locations. I have a function that creates a server, and assigns a protocol and want, from the client protocol in another file, make an AMP call to a method for stop the connector. The call AMP calls the SendMsg command. *class TESTServer(protocol.Protocol): factory = None sUsername = "" credProto = None bGSuser = None slot = None"""Here was uninteresting code.""" # upwards=self.bGSuser, forwarded=True, tx_timestamp=iTimestamp,\ # message=sMsg) log.msg("self.connector") log.msg(self.connector) return {'bResult': True} SendMsg.responder(vSendMsg) def _testfunction(self): logger = logging.getLogger('server') log.startLogging(sys.stdout) pf = CredAMPServerFactory() sslContext = ssl.DefaultOpenSSLContextFactory('key/server.pem',\ 'key/public.pem',) self.connector = reactor.listenSSL(1234, pf, contextFactory = sslContext,) log.msg('Server running...') reactor.run()if __name__ == '__main__': TESTServer()._testfunction()* The class CredAMPServerFactory assign the corresponding protocol. *class CredAMPServerFactory(ServerFactory): """ Server factory useful for creating L{CredReceiver} and L{SATNETServer} instances. This factory takes care of associating a L{Portal} with the L{CredReceiver} instances it creates. If the login is succesfully achieved, a L{SATNETServer} instance is also created. """ protocol = CredReceiver* In the "CredReceiver" class I have a call that assigns the protocol to the TestServer class. I do this to make calls using the AMP method "Responder". * self.protocol = SATNETServer* My problem is that when I make the call the program responds with an error indicating that the connector doesn't belong to CredReceiver attribute object. * File "/home/sgongar/Dev/protocol/server_amp.py", line 248, in vSendMsg log.msg(self.connector)exceptions.AttributeError: 'CredReceiver' object has no attribute 'connector'* How could I do this? Does anyone know of a similar example of that may take note? Thank you.

[Twisted-Python] Building Twisted 13.2.0 packages for RH 7.0
by Kobi Bar 03 Nov '15

03 Nov '15

Hi, I need to build twisted 13.2.0 packages for RH 7.0. I downloaded the source from https://pypi.python.org/packages/source/T/Twisted/Twisted-13.2.0.tar.bz2#md…. Currently, I'm able to build only one package "python-twisted-13.2.0-1.x86_64.rpm" (by running the command "python setup.py bdist_rpm") which contains all the sub-projects. How can I build separate package for each twisted sub-project (e.g. conch, core, mail, web, etc...)? I would like to have the following twisted packages at the end: python-twisted-13.2.0-1. x86_64.rpm python-twisted-conch-13.2.0-1.x86_64.rpm python-twisted-core-13.2.0-1.x86_64.rpm python-twisted-lore-13.2.0-1.x86_64.rpm python-twisted-mail-13.2.0-1.x86_64.rpm python-twisted-names-13.2.0-1.x86_64.rpm python-twisted-news-13.2.0-1.x86_64.rpm python-twisted-runner-13.2.0-1.x86_64.rpm python-twisted-web-13.2.0-1.x86_64.rpm python-twisted-words-13.2.0-1.x86_64.rpm The main reason is that some packages depends on twisted sub-projects, and therefore, their installation fail (e.g. python-txzmq requires python-twisted-core).

[Twisted-Python] INCOMPATIBLE CHANGE: removing dependency on PyCrypto
by Glyph Lefkowitz 02 Nov '15

02 Nov '15

There are a few places within Conch which currently export PyCrypto objects as part of a public interface in Twisted. These include: twisted.conch.ssh.keys.Key.keyObject twisted.conch.ssh.keys.objectType I'm working on a ticket - https://twistedmatrix.com/trac/ticket/7413 - to eliminate the dependency on PyCrypto. Right now, in that branch, those objects are Cryptography key objects instead of PyCrypto key objects. It is possible to preserve compatibility with keyObject, and we could deprecate and then remove objectType, with conditional dependencies on PyCrypto. But before I go through the effort there, I'm wondering if any users of conch actually care. -glyph

[Twisted-Python] Possible bug
by Chris Norman 02 Nov '15

Hi all, Using windows 10 with Python 3.5, importing pretty much anything gives me the following error. Not sure if there's something wrong with my configuration or if it's a bug... I seem to remember something a while back, should I file a ticket? Traceback (most recent call last): File "<string>", line 1, in <module> File "C:\python35\lib\site-packages\twisted\internet\reactor.py", line 38, in <module> from twisted.internet import default File "C:\python35\lib\site-packages\twisted\internet\default.py", line 56, in <module> install = _getInstallFunction(platform) File "C:\python35\lib\site-packages\twisted\internet\default.py", line 50, in _getInstallFunction from twisted.internet.selectreactor import install File "C:\python35\lib\site-packages\twisted\internet\selectreactor.py", line 18, in <module> from twisted.internet import posixbase File "C:\python35\lib\site-packages\twisted\internet\posixbase.py", line 18, in <module> from twisted.internet import error, udp, tcp File "C:\python35\lib\site-packages\twisted\internet\udp.py", line 53, in <module> from twisted.internet import base, defer, address File "C:\python35\lib\site-packages\twisted\internet\base.py", line 23, in <module> from twisted.internet import fdesc, main, error, abstract, defer, threads File "C:\python35\lib\site-packages\twisted\internet\defer.py", line 29, in <module> from twisted.python import lockfile, failure File "C:\python35\lib\site-packages\twisted\python\lockfile.py", line 52, in <module> _open = file NameError: name 'file' is not defined Cheers,
