[Twisted-Python] Buildbot downtime
by Tom Prince 03 Mar '22

03 Mar '22

I am plannig to upgrade twisted's buildbot in the near future. In preperation for that, I am going to take down the production buildbot on Tuesday, June 26, around 1600 UTC[1]. During that time, the result of any builds done will be lost. Thus, I'd ask that people avoid committing to trunk during that time. I will send a reminder before I take down the buildbot both here, and on #twisted and #twisted-dev. Tom [1] http://timeanddate.com/worldclock/meetingtime.html?iso=20120626&p1=80&p2=22…

help us launch a new, cool website for Twisted
by Glyph 25 Aug '21

25 Aug '21

Hi Twistors, In case you missed it, we have now finally actually done something with twisted.org <http://twisted.org/> - thanks to Thomas Grainger, the top level of the domain is a Github Pages public site, which means you can contribute to it with fairly standard tools if you are so inclined! The repo is here: https://github.com/twisted/twisted.github.io <https://github.com/twisted/twisted.github.io>. Trac will get migrated to new hardware somehow, volunteers are hard at work on that, but we should really move all the content that is hosted, for example, on the front page of twistedmatrix.com <http://twistedmatrix.com/> out of a trac wiki entirely, and into a more contributor-friendly space. This new domain is an opportunity to do that. If you have a vision for what you'd like a clean, modern Twisted website to look like, well, you're only a PR away from achieving your dream. And if you just love website implementation but don't care about realizing your own vision (???), a literal straight port of the existing design into static HTML via some processor like Pelican so that others could contribute content would be much appreciated as well :-). -g

AMP fields >64k
by Ian Haywood 24 Aug '21

24 Aug '21

I need to push messages to clients stuck behind a firewall. Existing solutions use polling of various forms. AMP would be perfect but for the 64k field size limit. There has been a previous attempt to address this (https://github.com/twisted/twisted/pull/1417) however this was reverted with a request to split the PR into the type annotations (presumably uncontroversial) and the protocol changes. The original contributor has done the type annotations (https://github.com/twisted/twisted/pull/1459) but they seem to be in "review queue hell" Can someone take a look and either merge it or specify what further work needs to be done? With regard to the protocol changes there was discussion of using netstrings. Is there any interest in a AMPv2 based on netstrings? Ian

[Twisted-Python] Twisted v21.2.0 breaks Crossbar.io
by Tobias Oberstein 24 Aug '21

24 Aug '21

Hi all, rgd Twisted v21.2.0, thanks a lot to all involved in this release! the release, mypy, more py3, .. +1! really appreciated. now, fwiw, just wanted to let you know (sorry, too late) about a regression with https://github.com/crossbario/crossbar that actually originates from https://github.com/crossbario/autobahn-python/issues/1470 => with Twisted v20.3.0 calling twisted.internet.protocol.ProcessProtocol.getPeer raises an AttributeError with Twisted v21.2.0 calling the same method raises an NotImplementedError => this fix broke our workaround for the bug now fixed;) https://github.com/crossbario/autobahn-python/pull/1469/files and released in: https://pypi.org/project/autobahn/21.3.1/ https://pypi.org/project/crossbar/21.3.1/ Cheers, /Tobias

[Twisted-Python] new success story: Battlehouse Games
by Glyph 16 Aug '21

16 Aug '21

I ran across a PyCon APAC talk about this, and the speaker generously offered to write a blurb for our site, which I've posted here: https://twistedmatrix.com/trac/wiki/SuccessStories#BattlehouseGames <https://twistedmatrix.com/trac/wiki/SuccessStories#BattlehouseGames> > Battlehouse creates and operates massively-multiplayer strategy games for browser and desktop platforms. Our most popular titles are nearly 10 years old and have served over 4 million users. > > Twisted plays an important role in our Python-based server stack. We use Twisted to handle many protocols including HTTP, WebSockets, and SQL. The asynchronous coroutine model helps us deliver low-latency gameplay without adding too much complexity to the codebase. Across 10 years of continuous evolution, Twisted has proven to be the most stable, well-documented, and flexible low-level networking library for Python. > > -- Dan Maas, CTO, Battlehouse Games Do you have your own success story? Please contact success(a)twistedmatrix.com <mailto:success@twistedmatrix.com> - it's always nice to hear from users! -g

Does connectTCP take a bytes or a str?
by Richard van der Hoff 09 Aug '21

09 Aug '21

[Shiny new list address! This is exciting!] So... IReactorTCP.connectTCP claims that 'host' should be a 'bytes': https://twistedmatrix.com/documents/current/api/twisted.internet.interfaces… PosixReactorBase.connectTCP doesn't tell us what type it should be, but, via tcp.Connector, ends up using it to construct an IPv4Address, which reckons it should be a 'str': https://twistedmatrix.com/documents/current/api/twisted.internet.address.IP…. Connector also uses it to construct a tcp.Client, where it gets used as part of tcp.Client.addr, which is again supposed to be a 'str'. I think in practice, either works, but it looks like most things *expect* it to be a 'str', with grudging support for 'bytes'. So my impression is the definition of the interface is wrong. Any thoughts/comments? (While we're at it, IReactorTCP also claims that 'timeout' and 'bindAddress' are required parameters, even though all the implementations make them optional.)

[Twisted-Python] Twisted Python 0.7.0 Prerelease Testing
by Glyph Lefkowitz 05 Aug '21

05 Aug '21

hi there, folks: I'd really like to release 0.7.0 but I would like it to be at least a little bit tested before I do so. Could those of you with CVS trees check everything out and see if it performs as advertised? Deeper bugs than that will have to wait for the next release, but I'd at least like to know if it works for someone other than me. Thanks. ______ __ __ _____ _ _ | ____ | \_/ |_____] |_____| |_____| |_____ | | | | @ t w i s t e d m a t r i x . c o m http://www.twistedmatrix.com/~glyph/

test for mailing list alias
by Glyph 05 Aug '21

05 Aug '21

Hello again, Sorry for all the operations-related noise folks, just wanted to send one final message to be sure that the list alias works for anyone who hasn't updated their addressbooks yet. After this I think we'll be back to normal operations, at least for the mailing list. -g

[Twisted-Python] bad news about twistedmatrix.com's hosting
by Glyph 04 Aug '21

04 Aug '21

Hello Twistors, Our venerable hosting provider, tummy.com <http://tummy.com/>, will be terminating their business operations on September 30, 2021. >>> datetime.date(2021, 9, 30) - datetime.date.today() datetime.timedelta(days=60) In addition to being a bit personally sad - Tummy has been an avid supporter of the Twisted community since the very beginning - this means we have just about 60 days to fully migrate our website, mailing list, and DNS's hosting from Dornkirk, the machine where it's been running continuously since 2013, to ... something else. There are 2 problems here: We need a sponsor to help us find a new hosting or cloud provider where things can be hosted. We do pay tummy currently, and we can probably ask the SFC to pay a different hosting provider a similar price for equivalent services, but ideally we'd find someone willing to donate something so as not to put a drain on those resources. I will need significant help with the operational aspects of the migration. I typically do a bunch of behind-the-scenes system administration for twistedmatrix.com <http://twistedmatrix.com/> to keep the whole thing clunking along, but after my brain has been fried by a year and a half's worth of pandemic stress, I simply don't have the time, energy, or mental capacity to do this. I know I've asked for help before and rarely received any, but if I have to do this entirely by myself, the most likely outcome is that I'll migrate DNS to some free cloud thing so at least my email address doesn't break (I migrated SMTP, and thereby everything associated with personal email addresses to Mailgun some years ago, so Tummy is not in that loop for that), and the website (and this mailing list) will simply stop working sometime between now and October. So if you'd like to keep www.twistedmatrix.com <http://www.twistedmatrix.com/>, speed.twistedmatrix.com <http://speed.twistedmatrix.com/>, our IRC bot (which is offline anyway right now due to Freenode shutting down), https://twistedmatrix.com/highscores/ <https://twistedmatrix.com/highscores/>, this mailing list, or our dogfooding instance for Twisted Names DNS, please volunteer so we can start to coordinate. If you've been wanting to just use Github Issues and don't care about preserving any of the data in Trac, congratulations, you're about to win that argument by default ;-). In the worst case scenario, I will download a backup image before things get turned off in case someone wants to deal with this -g

[Twisted-Python] Announcing the migration to the Python Org Mailing Lists hosting
by Adi Roiban 03 Aug '21

03 Aug '21

Hi, This is a quick message to let you know that the current mailing list service will migrate from the Twisted own hosted services to the mailing list service provided by the Python organization. The migration is scheduled to start on the 5th of August, 2021 17:00 UTC time (10:00am PDT / 18:00 BST) The following email address will no longer be available: twisted(a)twistedmatrix.com The new address will be: twisted(a)python.org The new archive will be hosted at the following link that will be available after the migration: https://mail.python.org/archives/list/twisted@python.org/ All existing subscribers will be migrated. If you only interact with the mailing list using your email you only need to update your existing filters and update your email contact address for the list. The migration is expected to take about 3 hours. After the migration, Glyph plans to implement an email redirection, so even if you send emails to the old address we should still receive them. Subject to availability :) We also plan to redirect (via HTTP 308) the old mailing list pages and archives to the new pages. This will also happen after the migration. Have a nice day... and talk to you soon on the new mailing list. PS: while we do the migration you can still get in touch using IRC on Libera #twisted channel Matrix/Gitter at https://gitter.im/twisted/twisted -- Adi Roiban

Re: [Twisted-Python] Moving the Twisted-Python and Twisted-Web mailing lists too Python mailman3
by Thomas Grainger 02 Aug '21

02 Aug '21

> Great news. I'd be happy to move the mailing lists over to let someone else maintain their infrastructure. Particularly if we could get off of Mailman 2, which has been no fun to maintain. > Many personal email addresses of core team members (including, um, this one) are forwarded by our mail hosting provider, Mailgun, and so moving the MX records directly is a non-starter, but we could easily point lists.twistedmatrix.com <http://lists.twistedmatrix.com/> at python.org <http://python.org/>, or we could just use @python.org addresses and be quite happy. twisted at python.org <mailto:twisted at python.org> would be very cool. We could also maintain a forwarding alias for compatibility for a little while, but I'd kinda rather deprecate posting to twisted-python at twistedmatrix.com <mailto:twisted-python at twistedmatrix.com> for a couple of other reasons anyway. A forwarding alias seems the best choice. twisted(a)python.org is indeed cool > Do we have a way to get our pipermail archive URLs (which are linked in tickets, in source code, etc) to redirect to the fancy new hyperkitty interface, or should those just be static HTML? (I'm kinda fine with either, honestly, although the former would be nice if we can manage it easily.) I think the redirects would be fairly easy as the URL structure is the same > I am happy to coordinate off-list about a secure way to exchange these data files (or anyone with administrator access to Dornkirk can just do it directly). Please send the announcement of the new address here first so we know when to cut over posting, and so that folks aren't surprised to see a new list-id. I can do magic wormhole > (At this point I think I'm happy to just nuke twisted-web as part of this migration; we can keep the archive up as static HTML for posterity, but it's mostly unused at this point, and the distinction doesn't make sense.) I actually think it's better to move twisted-web first and see what it looks, then mess about there with redirects, then do the main mailing list. I think the redirects would be fairly easy as the URL structure is the same Thomas Grainger

The twisted-web list seems pretty inactive currently, but twisted-python seems fairly active. Ideally we can arrange a time for you to shut down the lists and get me the files and get the lists up on mail.python.org. Otherwise, if the lists are still operational while I'm getting the files and doing the imports, messages and perhaps other changes will be lost, although it is possible to import additional messages to the archives after the fact. I will be available to do this during the next two weeks, but I will not be available for the rest of August and the first two weeks of September. Thomas Grainger
