[Twisted-Python] Twisted 15.4.0pre1 Prerelease Announcement
by Amber "Hawkie" Brown Aug. 27, 2015

Aug. 27, 2015

Hello everyone! Another few months, another Twisted release. This one has a few more Py3 goodies in it! - twisted.positioning, the rest of twisted.internet.endpoints, KQueueReactor (for real this time), twisted.web.proxy/guard, and Trial (!!!) have all been ported to Python 3. - Twisted officially supports several more platforms: Py3.4 on FreeBSD, Py2.7/Py3.4 on Fedora 21/22, and Py2.7 on RHEL7. - Python 2.6 is no longer supported, and support for Debian 6, and RHEL6 has been removed because of this. - Support for the EOL'd platforms of Fedora 17/18/19 has been removed. - Twisted has moved to requiring setuptools for installation. - twisted.python.failure.Failure's __repr__ now includes the exception message. - 19 tickets in total closed! As usual, you can find the tarball and newsfile at http://twistedmatrix.com/Releases/pre/15.4.0pre1/ ! Please download them, test them, share them, appreciate them, make them a little nest so that they are comfortable. If there aren't any reported issues, this will be getting a full release soon. Twisted Regards, Amber "Hawkie" Brown GPG: https://keybase.io/hawkowl

[Twisted-Python] Screen clearing in the Manhole
by Peter Westlake Aug. 26, 2015

Aug. 26, 2015

I'm making a manhole service in the usual way: class PF(ServerProtocol): def protocolFactory(*a, **kw): return manhole.Manhole(namespace) realm = manhole_ssh.TerminalRealm() realm.chainedProtocolFactory = PF mh_portal = portal.Portal(realm) mh_portal.registerChecker(checker) manhole_service = TCPServer(0, manhole_ssh.ConchFactory(mh_portal)) manhole_service.startService() and I'd like to print a message when the terminal is opened. This change does it: class PF(ServerProtocol): def protocolFactory(*a, **kw): class Manhole(manhole.Manhole): def connectionMade(self): super(Manhole, self).connectionMade() self.terminal.write('Hello') return manhole.Manhole(namespace) and so does this version, which is better because t.c.i.i.ServerProtocol.connectionMade says it is the place to write messages: class PF(ServerProtocol): def protocolFactory(*a, **kw): return manhole.Manhole(namespace) def connectionMade(self): ServerProtocol.connectionMade(self) self.write('Hello') But in both cases, after the message the screen is cleared by what looks like a form feed, and another prompt is printed. So far I can't find where in the code this happens. Is there a way to print a message and not have it scrolled off the screen? Thanks, Peter.

[Twisted-Python] twisted on jython
by Glyph Lefkowitz Aug. 14, 2015

Aug. 14, 2015

We currently have an unsupported builder for Jython 2.7: <https://buildbot.twistedmatrix.com/builders/ubuntu15.04-jython2.7 <https://buildbot.twistedmatrix.com/builders/ubuntu15.04-jython2.7>> This is great, so that we can fix issues that make Twisted not support Jython, but some of the bugs that are causing it not to work may be on the Jython side as well. Hawkowl, would it be possible to set up a Jython trunk builder? This will remain unsupported, of course, but it would give the Jython developers the ability to see how changes they make are affecting Twisted's progress to a supported version - and possibly cut a release on their end if it turns green ;). -glyph

[Twisted-Python] please can haz code review -> Tor-ified Twisted Python HTTP proxy server - txtorhttpproxy
by David Stainton Aug. 13, 2015

Aug. 13, 2015

Dear Twisted/Tor developers, I am motivated by language security concerns. I think Twisted Python can often implement excellent replacements for our old crufty C implementations. In this case I'd like to stop using C programs running as root (or not root) to torify http connections... like privoxy, polipo, apt tor transport etc. Last year I wrote this little tor http proxy; yes it also handles RFC 2817 proxy CONNECT method as well: https://github.com/david415/txtorhttpproxy I wrote an AgentProxy that can proxy any sort of twisted http agent: https://github.com/david415/txtorhttpproxy/blob/master/txtorhttpproxy/proxy… It used to use more terrible underscore imports but Leif fixed the bit-rot and made it work with Twisted 15: https://github.com/david415/txtorhttpproxy/commit/38f1a0cfab586f7a8965a47e9… Is this project worthy of your precious 10 minutes to review it... so I can improve the code quality? If I get rid of this last terrible import: from twisted.web._newclient import ResponseDone then I'm not sure how to detect when to call the finish() method here: https://github.com/david415/txtorhttpproxy/blob/master/txtorhttpproxy/proxy… Sincerely, David Stainton

[Twisted-Python] incompatible change in 15.3 - something reviewers should look for
by Glyph Aug. 12, 2015

Aug. 12, 2015

In https://twistedmatrix.com/trac/changeset/45163 twisted.internet.application.service.Service to be a new-style class. Just to remind everyone, converting an old-style class to a new-style class is an incompatible change, and reviewers should look for this. We discovered this because this change breaks https://github.com/twisted/axiom, and probably it breaks other packages as well, since lots of things inherit from Service. So please remain diligent about looking for this in future changes. Now that it's been changed, reverting it in 15.4 would be another incompatible change, so we probably won't do that, but please keep an eye out in the future. -glyph

[Twisted-Python] Proposal -- Code of Conduct
by Moshe Zadka Aug. 12, 2015

Aug. 12, 2015

Hi everyone, I am sure everyone understands that the Twisted community would love more diversity. While it is hard to achieve, it should be easy to remove one of the obvious blockers -- making underrepresented groups feel more welcome. I think, and hope, that our IRC channel, our issue system and mailing list have been a friendly, pleasant place. This is an attempt to clarify what we mean by a "friendly, pleasant place". After some discussion on IRC, I volunteered to write up a Code of Conduct for Twisted. It is mostly an adaptation of Django's CoC -- I think Django has a nice track record of commitment to diversity, and, of course, we expect our communities to overlap. My current draft, including instructions on how to build it, is in https://github.com/moshez/twisted-coc . I have intentionally not made the built documents available, in an attempt to avoid someone picking them up before they're approved by us. Please respond if there are any concerns about the wording, anything that I missed and anything you think does not belong there. I hope we can achieve consensus, and have the Project Leadership Committee approve this (including approving the current committee -- I've volunteered to chair it, and Glyph and Amber (HawkOwl) have graciously agreed to be on it.) Thanks, Moshe Z.
