[Twisted-Python] Buildbot downtime
by Tom Prince March 3, 2022

March 3, 2022

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…

[Twisted-Python] Twisted Python 0.7.0 Prerelease Testing
by Glyph Lefkowitz Aug. 5, 2021

Aug. 5, 2021

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/

[Twisted-Python] txmongo vs. pymongo + callInThread
by Clayton Daley Oct. 13, 2015

Oct. 13, 2015

Are there any major disadvantages of using pymongo with callInThread instead of txmongo? I'd like to take advantage of some newer features in pymongo (unfortunately not available in txmongo) and it's certainly easier to maintain feature parity using callInThread. Clayton Daley

Is anyone using the silverberg CQL (Cassandra) library for Twisted in production? Just curious what people's experience with it is, since it appears to be the most recently updated Twisted/CQL project. -J

[Twisted-Python] Better usage of Twisted on multi core processor
by Sumanth Puram March 13, 2015

March 13, 2015

Hi all, I have a twisted TCP server to listens to client, processes requests, do mysql database operations if needed (using adbapi Connection pool) and return the result. Before deploying this in production, I want to know right way to configure the server. Since twisted is single threaded, how can I leverage multiple cores of my production machine (which has 6 cores and 16 GB RAM) ? One approach that I thought of was to start multiple instances of twisted server on different ports. This would help in using the other cores as well. What do you guys suggest ? Thanks -Sumanth

[Twisted-Python] (no subject)
by Adi Roiban Feb. 7, 2015

Feb. 7, 2015

As commented by @glyph Since we've added the buildbot link to trac pages, force-builds.py is basically obsolete. I think we should just scrub all mentions of it, and probably delete it. I have created a ticket to remove it and clean documentation: https://github.com/twisted/twisted-dev-tools/issues/5 Is there anyone else still using this tool? Should we keep it and rather than removing it, improve its documentation? Thanks! -- Adi Roiban

[Twisted-Python] Unit testing, trail, inlineCallbacks, deferreds and mocking
by Patryk Ściborek Jan. 30, 2015

Jan. 30, 2015

Hi! I've just started a new project using Twisted and I want to write unit tests since the beginning. Unfortunately I've got some trouble understanding how should I do it. I read 'Test-driven development with Twisted', read some articles on the web and searched on the mailing list but I couldn't find anything which make it clear for me. I've got a class: class SessionCleaner(object): def __init__(self, session_db, interval=10): self.session_db = session_db self.lc = task.LoopingCall(self.check_old_sessions) self.lc.start(interval) @defer.inlineCallbacks def check_old_sessions(self): log.msg('check_old_sessions()', logLevel=logging.DEBUG) try: old_sessions = yield self.session_db.get_old_sessions() for s in old_sessions: yield self.session_db.process_stopped(s) except txredisapi.ConnectionError as e: log.msg('check_old_sessions - connection error {}' .format(e), logLevel=logging.WARNING) session_db is a object with methods which makes some calls to Redis. Testing if __init__ works correctly is easy - I can mock task.LoopingCall and check if it was called with correct attributes. I've got trouble testing check_old_sessions. Since I'm writing unit tests I don't want to call real session_db methods and make real Redis queries. I'd like to mock them and test just few things: - is the method get_old_sessions called? - is the method process_stopped called N times with the arguments returned by mocked get_old_sessions? - is txredisapi.ConnectionError handled correctly? So is there any "right" way of mocking functions which returns deferreds? Or maybe I should test this method differently? Best regards, Patryk

[Twisted-Python] bringing TxMongo back from the brink!
by bret curtis Jan. 30, 2015

Jan. 30, 2015

Hello fellow Twistrons, let me introduce TxMongo, an asynchronous MongoDB client that has come up a few times in discussion on this list. The project isn't dead, it has been contributed to over the years though while the original author, Alexandre Fiori, reviews and accepts the pull requests. After helping make a new 0.6 release, with SSL support, we talked about the possibility of Amplidata taking on the future development of TxMongo and breathing new life into the project. We just need a new place to host the 'official' repository and reign in all the various forks. What better place to do that than Twisted's github organization, similar in nature to what was done with Ldaptor. Amplidata will be the primary driver in development, but new feature requests and patches are of course, always welcome. :) So what does everyone think of this?

[Twisted-Python] Twisted 15.0 Release Announcement
by HawkOwl Jan. 30, 2015

Jan. 30, 2015

Hi everyone! On behalf of Twisted Matrix Laboratories, I am honoured to announce that Twisted 15.0.0 is *here*! Highlights are: - SSLv3 is disabled by default by endpoints created by `twisted.internet.endpoints.serverFromString` and `twisted.internet.endpoints.clientFromString`. - inlineCallbacks now has introductory documentation, and now supports using the return statement with a value on Python 3. - `twisted.web.client.Agent` now supports using UNIX sockets. - `ProcessEndpoint` now has flow control, which makes it useful for many more protocols - A whole bunch of bug fixes and other improvements, with 70+ closed tickets. You can find the downloads at <https://pypi.python.org/pypi/Twisted> (or alternatively <http://twistedmatrix.com/trac/wiki/Downloads>). The full details of what’s new in the release is contained in the NEWS file <https://raw.githubusercontent.com/twisted/twisted/releases/release-15.0.0-7…>. As usual, many thanks to everyone who had a part in this release - the supporters of the Twisted Software Foundation, the developers who contributed code and documentation, and all the people building great things with Twisted! Twisted Regards, HawkOwl
