Twisted Matrix Laboratories

Migration Report

2013-05-18T08:14:00.003-07:00

I have completed the migration scripts for deploying the services currently running on cube. They have been run against our new machine, dornkirk which is currently running with a snapshot of data.

It can currently be accessed by putting

66.35.39.66     twistedmatrix.com speed.twistedmatrix.com

in /etc/hosts. Please tests it, and verify that things appear to be working, but be aware that any changes will be lost, when the transition occurs.

At some point Monday or Tuesday, there will be some downtime for mail and the mailing lists, as mail-service is migrated to the new machine. For those that have accounts on cube, your data will be copied to the new machine at this point.

On Wednesday, at about 10 MDT (16 UTC), there will be downtime of all twisted services, as live data is transfered over. This may last up-to a couple of hours.

This work is made possible by the sponsorship of individuals and organizations which have donated to the Twisted project, part of the Software Freedom Conservancy, a not-for-profit organization that helps promote, improve, and develop open source software. Thanks!

April end-month report

2013-05-03T16:22:00.001-07:00

During the second half of the month, I have concentrated on the continuing development tools to automate the deployment of twisted infrastructure.

I've also spent some time developing some command-line tools for interacting with trac. It currently support view tickets, listing review tickets, and grabbing attachments (including applying them in git with an appropriate commit message). I plan to add support for doing reviews, as well.

April mid-month Fellowship report

2013-04-18T10:15:00.001-07:00

During the first half of the month, 43 tickets got some attention that they would not have received without the sponsored development. The result was 17 closed tickets and 24 other tickets unblocked for other developers to resume work on.

I set up an official git mirror that contains all the branches, including release branches and tags on github and documented my workflow on the wiki.

I've documened how our current infrastructure (cube), and with the help of Jonathan Stoppani, I've been working on scripts to automate the deployment of its successor (dornkirk).

Join Twisted for Google Summer of Code and the Outreach Program for Women

2013-04-04T18:40:00.000-07:00

Twisted is once again participating in Google's Summer of Code this year, as well as the GNOME Outreach Program for Women. If you're a student interested in working on Twisted as part of a paid internship, please visit our Google SoC page. We use best practices like in-depth code reviews and full coverage unit tests, so this is a great way to improve your technical skills whether you're a beginner or an expert programmer.

In addition, Twisted is once again participating the GNOME Outreach Program for Women, with the generous support of Mozilla, providing a paid internship for one woman to spend the summer participating in and contributing to Twisted. Unlike Google's program, the outreach program is not restricted to students; if you qualify, we do encourage you to apply to both. This internship is appropriate for any level of open source experience.

If you have worked on an open source project before, great! If not, we'll help you learn the development and communication tools we use as part of the internship. Some Python experience is a prerequisite, and a small initial contribution to Twisted is a part of applying (if this sounds intimidating, don't worry, we'll help you pick a task to complete and you'll have lots of support as you work through submitting your first patch.) Please check out the full OPW and GSoC descriptions and apply today!

Welcome our new Twisted Fellow: Tom Prince

2013-03-01T11:00:00.002-08:00

Twisted is an open, community-based project that aims for the highest quality and technical standards. As a community-based open source project, Twisted is for the most part run by volunteers, with code contributed by users and developers. As part of our ongoing goal to produce reliable, maintainable software we have strict requirements for coding standards, unit testing and code reviews. Unfortunately, sometimes these goals work at cross purposes. For example, code reviews have become a bottleneck for our development process; they're hard thankless work. There's a reason they'll get you the most points in our high scores.

The Twisted Maintainer Fellowship is our attempt to bridge these two goals: to remove bottlenecks and get necessary work done, thus enabling more contributions from the community. By paying for the Fellow's efforts we can ensure an ongoing focus on the maintenance needs of Twisted, most importantly code reviews.

I am happy to announce that we have signed a contract with Tom Prince to be our new Fellow. Tom Prince is a core developer of Buildbot, who became a Twisted contributor last year via his involvement with the Buildbot project. As a result, he has been maintaining Twisted's buildbot deployment on a volunteer basis for the last eight months. He also maintains the buildbots of other open source projects.

As you can see from the progress report below, Tom is already hard at work! I encourage you to donate to Twisted via the Software Freedom Conservancy (a 501(c)3 non-profit). By paying for Tom's time you can help support our efforts to maintain and improve Twisted.

Tom Prince's First Progress Report

I'm pleased to announce that I have been accepted as a Twisted fellow and full-time maintainer for 2013. I've completed my first two weeks of development. I spent the majority of my time clearing the review queue, from 32 tickets when I started to a low of 4 tickets.

All told, 42 tickets got some attention that they would not have received without the sponsored development. The result was 10 closed tickets and 29 other tickets unblocked for other developers to resume work on.

This work is made possible by the sponsorship of individuals and organizations which have donated to the Twisted project, part of the Software Freedom Conservancy, a not-for-profit organization that helps promote, improve, and develop open source software. Thanks!

Twisted, Python 3, and You

2013-01-12T22:09:00.001-08:00

As we described in our last announcement, Twisted 12.3.0 contains partial support for Python 3.3. But what exactly does "partial support" mean? Unfortunately, It doesn't mean that Twisted is ready for you to use on Python 3, unless all you need is the core reactor functionality.

What it really means is that it's time for you, Twisted users who care about Python 3, to contribute patches that port specific modules to Python 3. Our development infrastructure is now set up to efficiently deal with such patches, and to keep modules working once they're ported.

We have a buildbot set up to run a subset of the tests on Python 3.
There is a list of supported modules that can be updated as new modules are ported, to ensure they keep working. Most of the modules which are particularly tricky have now been ported, so contributors should now just need to do the tedious work of examining each module for small things that need to be addressed.
There's a tool that the buildbot runs, which all Twisted developers (including you) can run to verify that everything is working properly on 3.x if you have a functioning local Python 3.3 installation. (This tool is an interim step until Trial itself is fully ported to 3.x.)
There's a milestone you can look at containing a list of tasks for python 3.x, although this list is not exhaustive. If you come up with some work that needs to be done to port a module to python 3, put the ticket in that milestone.

So, if you're interested in using Twisted for a project that runs on Python 3, it should be pretty quick to port the functionality you need and submit a patch.

Twisted 12.3.0 released

2012-12-26T05:24:00.002-08:00

On behalf of Twisted Matrix Laboratories, I am pleased to announce, in extremis, the release of Twisted 12.3.
161 tickets are closed by this release, with the following highlights:

Support for local parallel testing in trial
A new "react" function to easily run a single asynchronous function in a script with the reactor.
Partial support for Python 3.3.

Twisted 12.3 requires zope.interface 3.6.0 or later, so you may need to upgrade. Also, on Windows, Python 2.7 or later is now required.

For more information, see the NEWS file here: NEWS.txt
Download it now from: Twisted-12.3.0.tar.bz2 or Twisted-12.3.0.win32-py2.7.msi
Thanks to the supporters of Twisted via the Software Freedom Conservancy and to the many contributors for this release.

Second pre-release of Twisted 12.3.0

2012-12-20T07:01:00.000-08:00

As it turns out, making a 4th release in 2012 wasn't going to be easy! Thanks to the testing of David Reid, we found and fixed an issue with pip which was making installation difficult when zope.interface was missing. And we got another fix with the help of Eric Mangold, fixing the compilation on OpenBSD.

The tarballs of the second pre-release can be found here: http://twistedmatrix.com/~therve/12.3.0pre2/

Thank you for testing it again!

Seeking a Motivated Maintainer for Twisted

2012-12-14T17:20:00.000-08:00

The Twisted project, via the Software Freedom Conservancy, is seeking to recruit a full-time paid maintainer. We've got a fellowship proposal published on the wiki, but here are some highlights:

You will be working on an open source project and your contributions will be consumed by companies such as Google, Canonical, Lucasfilm/Disney, Rackspace, and Justin.TV to name a few.
We want to hire a full-time maintainer who will assist with the continued growth of the Twisted project.
Thanks to the meticulous work of your predecessors, we have a clear view of what your average week would look like in terms of tasks and responsibilities (more below).

Desired qualifications in a maintainer:

The ability to review code for suitability, stability, and clarity; to point out meritable work, and provide actionable feedback on how to improve the code when necessary.
The ability to implement features in the Twisted library.
A positive presence in Twisted's online community on IRC and the mailing list.
Have familiarity with the infrastructure of the Twisted project (including trac and buildbot).
Work to provide education or outreach on Twisted in other forums such as workshops, conferences, and user groups.

We will strongly consider someone with experience maintaining other open source projects, but with just a little Twisted experience, as long as such an applicant is passionate about and committed to becoming a Twisted expert.

During an average work week, the maintainer will distribute their work along these lines:

Code review (55%) Review code, apply patches, and set and enforce standards for code quality. Improve documentation and code test coverage.
Mailing list and IRC participation (10%) Encourage and participate in discussions on Twisted's mailing lists and IRC channels.
Bug report triage (5%) Supervise Twisted's ticket workflow to ensure that bug tickets are addressed and closed.
New feature development (30%) Serve as architect for the development and implementation of new features.

Furthermore, the Maintainer will provide a forthnightly written report of their progress to the Conservancy and the Twisted community.

Information on whom to contact in the event of your interest is provided at the bottom of the page.

We look forward to hearing from you!

First pre-release of Twisted 12.3.0

2012-12-14T06:17:00.001-08:00

Yes, you're reading well. For the first time ever (since 2008), we're actually pushing not 2, not 3, but 4 releases in a calendar year! Just to be able to use the fancy 12.3 version number.

But, apart from this nice label, this release also closes 158 tickets, among them:

Support for local parallel testing in trial.
A new "react" function to easily run a single asynchronous function in a script with the reactor.
Partial support for Python 3.3.

Note that only Python 2.7 is supported on Windows now. We also require zope.interface 3.6.0 or newer.

You can find the tarballs of the pre-release here: http://twistedmatrix.com/~therve/12.3.0pre1/

For more information, see the NEWS file.

Please download the tarballs and test them!

Quick Fix: Upgrading Zope Interface so you can work on Twisted trunk post-12.2 release

2012-09-02T19:30:00.002-07:00

Immediately after the recent 12.2 release, Twisted has upgraded its required version of Zope Interface. Some platforms ship with a system-installed version of Zope Interface that is slightly too old for this change. You may have noticed an unhelpful error message if you happened to svn up before learning about this change.

Upgrading system-installed Python packages without doing harm can be a challenge, so in this post we'll provide simple instructions for users who:

have a system-installed version of Zope Interface
are on a Unix-y platform, like Linux, BSD, or OS X (if you're on Windows, just upgrade to the latest on your system installation)
are not using a tool like virtualenv or Combinator to manage Zope Interface (if you are, you should already know what to do!)
don't want to upgrade anything system-wide, so as to avoid disturbing other users or software on their system
have easy_install already available in their environment. (While Pip is generally better, it is pre-installed less often, and Pip doesn't seem to deal as well as easy_install with the case of parallel installation of user and system installed dependencies; it assumes you are using virtualenv for that. Update: as of the most recent release, pip deals just fine with parallel user/system installation; so, if you've got pip installed, "pip install zope.interface==4.0.2" – possibly with a --user option if that's appropriate to your environment – will work just fine. Thanks, Pip maintainers!)

This set of attributes describes many Linux and OS X developers who are likely to encounter this version skew issue, so off we go.

Since easy_install can't be coerced to do the right thing by command-line options, you'll need to give it a configuration file that it can read. The easiest way to do this is to create a temporary directory, cd into it, and create a file called setup.cfg. For Linux and BSD, setup.cfg looks like this:

[install]
prefix=~/.local

For OS X, the file looks like this:

[install]
prefix=~/.local
install_lib=~/Library/Python/$py_version_short/lib/python/site-packages

Once you've created that file, just easy_install --upgrade zope.interface from that directory and you should be ready to start developing with Twisted again! All the older versions of Twisted that I've tried still work with the newest Zope Interface so this shouldn't disturb your ability to test your code against older versions of Twisted as well, if you're managing it with something like Combinator or virtualenv.

Twisted 12.2.0 Released

2012-09-02T19:29:00.003-07:00

On behalf of Twisted Matrix Laboratories, I am honored to announce the release of Twisted 12.2.

Highlights for this release include:

To be able to work on Python3 support, Python 2.5 is no longer supported.

twisted.mail.imap4 now serves BODYSTRUCTURE responses which provide more information and conform to the IMAP4 RFC more closely.
twisted.conch now supports commercial SSH implementations which don't comply with the IETF standard.
twisted.internet.endpoints now provides several new endpoints, including aTCP client endpoint that resolves hostnames to IPv6 host addresses.
IReactorSocket.adoptStreamConnection, implemented by some reactors, allows adding an existing established connection to the reactor.

Starting with the release after 12.2, Twisted will begin requiring Zope Interface version 3.6 or greater (as part of Python 3 support).

This is the last Twisted release supporting Python 2.6 on Windows.

For more information, see the NEWS file here:

Congratulations and welcome to Twisted's summer interns

2012-05-19T10:08:00.000-07:00

Twisted is excited to be supporting 4 full-time summer interns from around the world through 2 internship programs this summer.

Google Summer of Code internships

Expanded Endpoints Support, by Ashwini Oruganti (IRC nick ashfall)

Ashwini joins us from the Manipal Institute of Technology in Manipal, India. She has already worked on and closed out a number of Twisted tickets and has previously contributed to Evolution and Sugar Labs.

Her project:

Recently, two new APIs, IStreamServerEndpoint and IStreamClientEndpoint were added to Twisted, for specifying what address the servers should listen for connections and what address a client should connect to, respectively. But not all of the addresses that Twisted supports have this endpoint support added to them; presently endpoint support has been implemented for TCP, SSL and UNIX domain sockets. My project deals with adding more endpoint implementation to Twisted, some involving wrappers around the existing APIs (e.g. serial ports, standard I/O), others involving making fresh APIs where setting up connections was difficult before the addition of the endpoints (e.g. SOCKS and HTTPS proxies).

Python 3 preparation, by Vladimir Perić (IRC nick vperic)

Vladimir joins us from Czech Technical University in Prague. Last year he was a Google Summer of Code student with SymPy.

His project:

Python 3 is the future of Python. If Twisted is to see continued usage in the future, it will have to be ported, and rather sooner than later. As Twisted is a large and complicated code-base, this process needs to be done with care, ensuring that any code written remains compatible with the currently supported versions. The test-driven development methodology Twisted uses will ensure no regressions happen and will ease the maintenance of the code-base.

Automatic Coding Standard Enforcement, by Raphael Shu (IRC nick zomux)

Raphael joins us from Tsukuba University in Japan, where he uses Python daily in his NLP research.

His project:

Twisted applies certain naming and style standards to all contributed code. Currently, a human reviewer needs to check all of these things. The purpose of this project is to develop a tool which can automatically make these simple, mechanical checks, freeing up human reviewer time to focus on more important aspects of proposed changes. Finally, it will speed up the review process.

Software Freedom Conservancy / GNOME Outreach Program internship

We are also excited to be working with the Software Freedom Conservancy and the GNOME Outreach Program for Women this summer. You can read more about the initiative and our work to encourage diverse participation in open source communities here. Through this initiative we have a 4th paid, full-time internship this summer:

Improving Twisted Mail and Twisted Core, by Fei Tan (IRC nick argonemyth)

Fei joins us from Grand Bay, Mauritius, where she works as a freelance web developer.

She will improve Twisted Mail on a number of fronts, including improving API documentation, adding more examples, adding more HOWTOs, and improved test coverage.

Please join me in welcoming Ashwini, Vladimir, Raphael, and Fei, whose internships start next week. Expect a torrent of code reviews and some record-breaking high scores list stats this summer!

Thank you Google for giving us this paid mentorship opportunity, and thank you to the Python Software Foundation for supporting us as our Google Summer of Code umbrella organization.

Google Summer of Code and Outreach Program for Women

2012-03-31T06:59:00.000-07:00

Twisted is participating in Google's Summer of Code this year. If you're a student interested in working on Twisted as part of a paid internship, please visit our Google SoC page. We use best practices like in-depth code reviews and full coverage unit tests, so this is a great way to improve your technical skills whether you're a beginner or an expert programmer.

In addition, Twisted and its non-profit home the Software Freedom Conservancy have partnered with the GNOME Outreach Program for Women to fund an internship for one woman to spend the summer participating in and contributing to Twisted, while being mentored by Jessica McKellar. Jessica is a long-time Twisted contributor as well as a software engineer and an organiser, among other things, of the Boston Python Workshops for women.

Unlike Google's program, the outreach program is not restricted to students; if you qualify, we do encourage you to apply to both. This internship is appropriate for any level of open source experience. If you have worked on an open source project before, great! If not, we'll help you learn the development and communication tools we use as part of the internship. Some Python experience is a prerequisite, and a small initial contribution to Twisted is a part of applying (if this sounds intimidating, don't worry, we'll help you pick a task to complete and you'll have lots of support as you work through submitting your first patch.) Please check out the full project description and apply today!

Thank you David for organizing this, and Smarterer for hosting.

Thank you to everyone who closed out 2011 with contributions to Twisted!

November Sprint Report

2011-12-10T14:52:00.000-08:00

November saw another successful Sprint at the Smarterer.com offices, thanks to a smaller but extremely busy group of developers:

Reviewmeister(ess) Jessica McKellar secured second place in the Twisted High Score list with an impressive number of reviews, including:

#3037: "loseWriteConnection breaks loseConnection" (now resolved)
#4262: "Multicast documentation is misleading" (now resolved)
#538: "Website-template.tpl is out of date"

She also resolved #1247: ("kqreactor timeout error (traceback)"), and opened #5385, #5386, and #5387, while resolving #5060: ("Correct python requirement in twisted/topfiles/setup.py").

Not to mention all the tickets reviewed at recent Sprints which have since been resolved! (Though, to mention them anyway, #1247, #2115, #2447, #2498, #2507, and #5370)

Eternal High Score Overlord JP Calderone made a fair showing as well, finishing #5371 ("In the developer guide, forbid new global reactor unit tests"), and splitting #4671 ("sometimes I want to have some constant values that are part of a set") into more managable tickets:

#5382: "Provide a library for valueless named constants"
#5383: "Provide a library for simple valued named constants"
#5384: "Provide a library for bitvector-like valued named constants"

Of which #5382 and #5383 saw immediate progress.

Returning Champion Sprinter Paul Swartz reviewed and otherwise worked on several tickets, including:

#2997: "Conch and getPeer"
#5352: "Do not register overlapping old DH key exchange messages"
#1902: "Compatibility work-around for commercial SSH 2.0.12 misbehaviours"
#3242: "Use python 2.5 'spwd' module instead of z3p secret 'shadow' module when available"

One-word Twisted celebrity Glyph was also on hand to assist with the reviews of #3242, #5382, and #1918

With considerably more words in his name, Itamar Turner-Trauring started porting a Nevow branch with IRI support (internationalized URLs) to Twisted as per ticket #5388, as well as helping resolve #3037 with Jessica.

Finally, Glyph, Itamar, and Dave Sturgis conferred on #288, and the related cluster of web-resource-model issues it involves; It is hoped that this will eventually result in a new Web Server URL Traversal API, or WSURLTA, not to be confused with the nordic kraken-headed demigod of lore.

Twisted 11.1.0 has been released!

2011-11-17T10:29:00.000-08:00

Twisted Matrix Laboratories is proud to announce the release of Twisted 11.1, thanks to the efforts of our release manager Thomas Hervé.

Highlights of the 185 tickets closed include:

The poll() reactor as default where applicable, instead of select() everywhere.
A new SSL implementation only relying on OpenSSL for cryptography, (not I/O) making it more robust.
Several improvements to the fresh HTTP/1.1 client implementation, including proxy and cookie support.
Thomas' personal favorite: a new howto has been published on test-driven development with Twisted.
A new abortConnection() method for immediately closing TCP and SSL connections, the oldest ticket closed by this release.

For more information, see the NEWS file. Note that this is the last release supporting Python 2.4 (the support on Windows stopped with 11.0).
