[Twisted-Python] Wiki page edit
by Jason Litzinger 17 May '17

Hello, In going through the instructions on https://twistedmatrix.com/trac/wiki/TwistedDevelopment#Creatingyourworkenvi… I noticed an error in the invocation of the twistedchecker-trunk-diff command. The change needed is: # On Linux/OSX there is a helper to only raise error for the diff -./travis/twistedchecker-trunk-diff.sh src/twisted/ +./.travis/twistedchecker-trunk-diff.sh src/twisted/ I am happy to make the change, but I don't currently have edit permissions to the wiki (for reference, my trac username is jlitzingerdev). Cheers, -Jason

[Twisted-Python] Combining eventually and incremental dependencies
by Adi Roiban 16 May '17

16 May '17

This is based on my review of https://twistedmatrix.com/trac/ticket/9111 Is there any real value in having many small python packages doing only a few things? Can we pack the deprecation code together with the versioning code... for example to only have 'incremental' ? I feel like we are going to the node.js path where you have a package for the strip function. I feel that having multiple separate project just adds a lot of extra admin works... set up repo permissions/ set up pypi access / set up CI integration / set up documentation. In the same time, I feel that deprecation and versioning functionalities are related. >From what I can see in the current examples, each time you use eventually you are forced to use incremental so that you can pass that bloody Version instance, which I don't know why we can't go with just a tupple :) Thanks! -- Adi Roiban

[Twisted-Python] Buildbot and Python 3
by Craig Rodrigues 15 May '17

15 May '17

Hi, I've shifted efforts to port buildbot to Python 3. In March, we reached a milestone where all of buildbot's unit tests passed on Python 3: https://medium.com/buildbot/buildbot-0-9-5-is-out-1d83626bd95a This effort was possible due to large parts of Twisted (especially Perspective Broker) now working on Python 3. Buildbot is a heavy user of Twisted. There are a couple of bugs in Twisted's Python 3 support uncovered by buildbot which need to get fixed/merged in Twisted. Hopefully these can get fixed and a new version of Twisted can be released so that buildbot works out of the box on Python 3. -- Craig

[Twisted-Python] HTTP PUT a GET's streaming response with treq
by Nagy, Attila 06 May '17

06 May '17

Hi, I would like to copy a file between two HTTP servers in the most efficient manner, which probably means a streaming down/upload (GET/PUT) with the producer/consumer scheme. Can this be done easily, could somebody write a simple example? Thanks,

[Twisted-Python] process manager for twisted daemons?
by jonathan vanasco 04 May '17

04 May '17

We have a few twisted daemons running on a linux machine under Supervisord as the process manager. Unfortunately, Supervisord is missing a feature that is pretty critical to our needs, so must be replaced with something that supports it -- the feature is the ability to persist state across reboots. We've run into a situation more than once where we "stop" a Twisted service that caused issues, begun to triage it, and then the machine hits a reboot which causes the broken service to start up again and re-corrupts the data. The only way to maintain a "stop" across reboots in Supervisor is to "stop", then edit the config files so it doesn't start up again. If someone remembers to shut things off this way, they often forget to turn them back on again. We're at the point where using supervisor in our stack has caused more problems than conveniences. Is anyone deploying their twisted services with something other than Supervisor? If so, I'd love to know.

[Twisted-Python] new core contributor
by Glyph Lefkowitz 01 May '17

01 May '17

As per our previously documented entirely arbitrary[1] and ad-hoc[2] process, I'd like to welcome - should he choose to accept it - Tom Most to be a member of the Twisted project. You've probably seen him around on IRC, as 'twm'. Tom's been reporting nuanced web-related bugs in Twisted since at least 2011, if not longer: https://twistedmatrix.com/trac/ticket/5434 <https://twistedmatrix.com/trac/ticket/5434> Tom has been around in the Twisted community for the last few years, and he's been particularly helpful in some recent discussions around correct behavior with respect to various web standards, and participation in Treq and Klein. He's been stalled a number of times by not having commit access, so: no more excuses, now. Tom, please read https://twistedmatrix.com/trac/wiki/CommitterCheckList <https://twistedmatrix.com/trac/wiki/CommitterCheckList> and then go do some code reviews :). -glyph [1]: https://www.mail-archive.com/twisted-python@twistedmatrix.com/msg10236.html [2]: Want better governance for Twisted? Volunteer to help operate this process - https://twistedmatrix.com/trac/wiki/Proposal/ContributorAdvancementPath <https://twistedmatrix.com/trac/wiki/Proposal/ContributorAdvancementPath> - or something like it ;-).
