[Twisted-Python] Twisted Web documentation out of date
by Pierre Jaury 13 May '13

13 May '13

Twisted Web documentation still refers to some deprecated objects that have been removed from Twisted 13.0. For instance, the latest version of this page : http://twistedmatrix.com/documents/current/web/howto/web-in-60/error-handli… refers to NoResource as being part of the twisted.web.error module while it was moved to twisted.web.resource a while ago. I did not find any other outdated reference for now, yet this might not be as isolated as it seems. Regards, Pierre. -- Pierre Jaury <pierre(a)jaury.eu> Weblog - http://kaiyou.fr GPG ID - E804FB60

by meejah 12 May '13

12 May '13

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 txtorcon 0.8.0 is now tagged and released. [1] txtorcon is a Python+Twisted-based asynchronous implementation of the Tor control protocol. It includes a state-tracking abstraction, configuration abstraction, Twisted endpoint support for hidden services, 96%+ unit-test coverage and many examples. New in this release: . issue #18: slight *API change* ICircuitListener.circuit_failed, circuit_closed, IStreamListener.stream_failed, stream_closed and stream_detach all now include any keywords in the notification method (these either lacked flags, or only included some) . launch_tor() can take a timeout (starting with a patch from hellais); . cleanup from aagbsn; . more test coverage; . run tests cleanly without graphviz (from lukaslueg); . issue #26: fix from lukaslueg; . pep8 and whitespace targets plus massive cleanup (now pep8 clean, from lukaslueg); . issue #30: fix reported by webmeister making ipaddr actually-optional; . example using synchronous web server (built-in SimpleHTTPServer) with txtorcon (from lukaslueg); . TorState can now create circuits without an explicit path; . passwords for non-cookie authenticated sessions now use a password callback (that may return a Deferred); . fixes for AddrMap in case Tor ticket #8596 is implemented; Code and built documentation may be obtained: git clone git://github.com/meejah/txtorcon.git https://github.com/meejah/txtorcon https://txtorcon.readthedocs.org/en/latest/index.html You may easily install it: pip install txtorcon easy_install txtorcon The sha256sum output is: 87fcb3bce3ac3b48583f637bf69445bd50071411dc3fded89df7600d870a3094 txtorcon-0.8.0.tar.gz thanks, meejah [1] -- (Note the tagging took place last month, and I've only now updated PyPI, ReadTheDocs, freecode, emailed this, ...) -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iQEcBAEBAgAGBQJRjy+yAAoJEJ0UOBRRgEVQXrMH/0Kl3DmVLyqo3aTBNv1d50RL yi8u5LTZLNtuYiyJsxqTFyq8zNhfEwIPoXbsqHyNuv0hv8s6Qn4OkXh47/crhukO GpnNNTldvSQIpOfNw+ftCYF/NC0X5pOjJo/Rz1XUkFyms50cqq17i+MWvcAvaFnW Ols6+7ulh8u61ElafVxnwn1zgitkpUOOsnF8a27iXryFJ/iZFFROnCigJv2eM8pj SqcwKbVp9h1VtztoYhtEcjEPBm1NnrYGoRIjh9D3RQfEVnXgM2fU4HoGhFAqYj7M wFZv0DZBvL2s/XwV8PEi4Y4+fTJZTXE7bbHctMWjUWjhlMfMniq2oud4hZJ5ugY= =MDAq -----END PGP SIGNATURE-----

[Twisted-Python] ANNOUNCING Tahoe-LAFS v1.10
by Zooko Wilcox-OHearn 10 May '13

10 May '13

Folks: Tahoe-LAFS is built on Twisted and uses Twisted extensively for networking, event queue, and more. If you want to hack on a distributed storage system written in Twisted, you are welcome to join us! Here is our new Release Announcement. Regards, Zooko ------- ANNOUNCING Tahoe, the Least-Authority File System, v1.10 The Tahoe-LAFS team is pleased to announce the immediate availability of version 1.10.0 of Tahoe-LAFS, an extremely reliable distributed storage system. Get it here: https://tahoe-lafs.org/source/tahoe-lafs/trunk/docs/quickstart.rst Tahoe-LAFS is the first distributed storage system to offer "provider-independent security" — meaning that not even the operators of your storage servers can read or alter your data without your consent. Here is the one-page explanation of its unique security and fault-tolerance properties: https://tahoe-lafs.org/source/tahoe-lafs/trunk/docs/about.rst The previous stable release of Tahoe-LAFS was v1.9.2, released on July 3, 2012. v1.10.0 is a feature release which adds a new Introducer protocol, improves the appearance of the web-based user interface, improves grid security by making introducer FURLs unguessable, and fixes many bugs. See the NEWS file [1] for details. WHAT IS IT GOOD FOR? With Tahoe-LAFS, you distribute your filesystem across multiple servers, and even if some of the servers fail or are taken over by an attacker, the entire filesystem continues to work correctly, and continues to preserve your privacy and security. You can easily share specific files and directories with other people. In addition to the core storage system itself, volunteers have built other projects on top of Tahoe-LAFS and have integrated Tahoe-LAFS with existing systems, including Windows, JavaScript, iPhone, Android, Hadoop, Flume, Django, Puppet, bzr, mercurial, perforce, duplicity, TiddlyWiki, and more. See the Related Projects page on the wiki [3]. We believe that strong cryptography, Free and Open Source Software, erasure coding, and principled engineering practices make Tahoe-LAFS safer than RAID, removable drive, tape, on-line backup or cloud storage. This software is developed under test-driven development, and there are no known bugs or security flaws which would compromise confidentiality or data integrity under recommended use. (For all important issues that we are currently aware of please see the known_issues.rst file [2].) COMPATIBILITY This release should be compatible with the version 1 series of Tahoe-LAFS. Clients from this release can write files and directories in the format used by clients of all versions back to v1.0 (which was released March 25, 2008). Clients from this release can read files and directories produced by clients of all versions since v1.0. Servers from this release can serve clients of all versions back to v1.0 and clients from this release can use servers of all versions back to v1.0. Except for the new optional MDMF format, we have not made any intentional compatibility changes. However we do not yet have the test infrastructure to continuously verify that all new versions are interoperable with previous versions. We intend to build such an infrastructure in the future. The new Introducer protocol added in v1.10 is backwards compatible with older clients and introducer servers, however some features will be unavailable when an older node is involved. Please see docs/nodekeys.rst [14] for details. This is the eighteenth release in the version 1 series. This series of Tahoe-LAFS will be actively supported and maintained for the foreseeable future, and future versions of Tahoe-LAFS will retain the ability to read and write files compatible with this series. LICENCE You may use this package under the GNU General Public License, version 2 or, at your option, any later version. See the file "COPYING.GPL" [4] for the terms of the GNU General Public License, version 2. You may use this package under the Transitive Grace Period Public Licence, version 1 or, at your option, any later version. (The Transitive Grace Period Public Licence has requirements similar to the GPL except that it allows you to delay for up to twelve months after you redistribute a derived work before releasing the source code of your derived work.) See the file "COPYING.TGPPL.rst" [5] for the terms of the Transitive Grace Period Public Licence, version 1. (You may choose to use this package under the terms of either licence, at your option.) INSTALLATION Tahoe-LAFS works on Linux, Mac OS X, Windows, Solaris, *BSD, and probably most other systems. Start with "docs/quickstart.rst" [6]. HACKING AND COMMUNITY Please join us on the mailing list [7]. Patches are gratefully accepted -- the RoadMap page [8] shows the next improvements that we plan to make and CREDITS [9] lists the names of people who've contributed to the project. The Dev page [10] contains resources for hackers. SPONSORSHIP Atlas Networks has contributed several hosted servers for performance testing. Thank you to Atlas Networks [11] for their generous and public-spirited support. And a special thanks to LeastAuthority [12], which employs several Tahoe-LAFS developers, for their continued support. HACK TAHOE-LAFS! If you can find a security flaw in Tahoe-LAFS which is serious enough that we feel compelled to warn our users and issue a fix, then we will award you with a customized t-shirts with your exploit printed on it and add you to the "Hack Tahoe-LAFS Hall Of Fame" [13]. ACKNOWLEDGEMENTS This is the twelfth release of Tahoe-LAFS to be created solely as a labor of love by volunteers. Thank you very much to the team of "hackers in the public interest" who make Tahoe-LAFS possible. Brian Warner on behalf of the Tahoe-LAFS team May 1, 2013 San Francisco, California, USA [1] https://tahoe-lafs.org/trac/tahoe-lafs/browser/NEWS.rst [2] https://tahoe-lafs.org/trac/tahoe-lafs/browser/docs/known_issues.rst [3] https://tahoe-lafs.org/trac/tahoe-lafs/wiki/RelatedProjects [4] https://tahoe-lafs.org/trac/tahoe-lafs/browser/COPYING.GPL [5] https://tahoe-lafs.org/trac/tahoe-lafs/browser/COPYING.TGPPL.rst [6] https://tahoe-lafs.org/trac/tahoe-lafs/browser/docs/quickstart.rst [7] https://tahoe-lafs.org/cgi-bin/mailman/listinfo/tahoe-dev [8] https://tahoe-lafs.org/trac/tahoe-lafs/roadmap [9] https://tahoe-lafs.org/trac/tahoe-lafs/browser/CREDITS [10] https://tahoe-lafs.org/trac/tahoe-lafs/wiki/Dev [11] http://atlasnetworks.us/ [12] https://leastauthority.com/ [13] https://tahoe-lafs.org/hacktahoelafs/ [14] https://tahoe-lafs.org/trac/tahoe-lafs/browser/docs/nodekeys.rst

[Twisted-Python] Helping the Python 3 port
by Jonathan Ballet 09 May '13

09 May '13

Hi, I'm interested to give a help to port Twisted to Python 3. I gave a look at the tickets on Trac tagged with py3k and those in the Python-3.x milestone. I gave a try at http://twistedmatrix.com/trac/ticket/5802 to see what still needed to be done, and after rebasing the patch on trunk and starting to hack a few modules, I noticed that I have to do those 3 things in a bunch of places: * use the newer "except Exception as e" instead of "except Exception, e" * use the print function instead of the print statement * replace "implements(IFoo)" by the class decorator "@implementer(IFoo)" I can probably post a new patch which fixes all those things in order for Trial (as per #5802) to just start, but I wonder if this is the right approach and if it wouldn't be better to fix those first (since they are, AFAIK, compatible with Python 2.6 anyway). Any idea? Jonathan

[Twisted-Python] chain certificates on the command line?
by Glyph 06 May '13

06 May '13

With the recent resolution of <http://twistedmatrix.com/trac/ticket/2061>, I am wondering if there is already a plan in progress (and maybe some existing tickets) for adding intermediary chain certificate support to client and server endpoint string syntaxes? Apologies if I lost it somewhere in the somewhat lengthy discussion on that ticket :). -glyph
