[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] code contribution/participation policy
by Boris Epstein March 10, 2021

March 10, 2021

Hi all, I have started working with Twisted and found it to be a very powerful package. That said, some modules are not documented very thoroughly (big surprise in the world of software, right?) and I also found some questionable code, too. If I were to contribute fixes/improvements, what is the submission procedure? Thanks. Boris.

[Twisted-Python] More Conch Questions
by Robert DiFalco Dec. 1, 2020

Dec. 1, 2020

I'm continuing to wrestle with conch, this time around authentication and notifying deferred of auth failure. It seems like the SSH factory has a deferred to be notified of auth failures here: https://github.com/twisted/twisted/blob/trunk/src/twisted/conch/client/dire… Unfortunately, this deferred is cleared because prior to auth, it receives this on successful connect: https://github.com/twisted/twisted/blob/trunk/src/twisted/conch/client/dire… As you can see this clears the deferred so it is no longer available to get an errback. This also prevents the SSHClientTransport from getting a sendDisconnect. To try it change the user to something invalid here: https://gist.github.com/radifalco/5a5cca4bf8d49d5c61113e36f9be7553#file-sft… This will never get a callback to errback. I guess I would have expected this to get the error but it actually succeeds with None. As a result there is no deferred to get the auth failure and my app waits forever for a notification. There is one ting I *think* I know how to do, add a timeout with a callback later on the sftpClient deferred. But that seems lame. What I'd like to do is to get this ConchError as it has the actual reason for the connection failure. Thoughts? https://github.com/twisted/twisted/blob/trunk/src/twisted/conch/client/dire…

[Twisted-Python] ClientFactory design
by Peter Westlake Nov. 30, 2020

Nov. 30, 2020

I'm studying an SSH client implementation using Conch, and was surprised to see that the ClientFactory subclass had a connect() method which calls connectTCP. This isn't really a problem - the code works - but it seems like an odd place to do the connection. Am I right to be surprised? Peter.

[Twisted-Python] revert / rework of "AMPv2" change?
by Glyph Nov. 29, 2020

Nov. 29, 2020

I just glanced at https://github.com/twisted/twisted/pull/1417 <https://github.com/twisted/twisted/pull/1417> after it was merged and noticed a few problems: - It exposes a new top-level name rather than setting the protocol version as a parameter - The NEWS files are malformed which is going to lead to some confusing duplication in the changelog - AMPv2 itself does not appear to be "standardized" - the page at https://amp-protocol.net/conversations_v2.html <https://amp-protocol.net/conversations_v2.html> appears to be a preliminary suggestion for how long values might be handled rather than something broadly implemented; for one thing, I'd never heard of it before and for another the site itself doesn't link the document. This would be fine as a first draft, but I think it needs to be given some more revisions, given that (for example) there are a number of backwards-compatible ways to do this. - The layering is wrong because it puts the protocol-parsing into a leaf class in the hierarchy, when the parsing logic was deliberately isolated to a lower level to facilitate different framing mechanisms. - As JP pointed out, the tests have a potential bug where they can leak errors between cases. I don't normally like to revert folks' work once it's been reviewed and accepted, particularly when there's no process violation (broken CI, lack of code coverage etc), but I'm particularly concerned about lending Twisted's imprimatur to this protocol extension as a whole new version without much more context on who is implementing it and what other options were considered, particularly when I personally (nominally the inventor of AMP) don't like the direction it has taken :). What do other folks think? Anyone else have more of a finger on the pulse of where the "v2" conversation has been happening? -glyph

[Twisted-Python] smb component progress
by Ian Haywood Nov. 26, 2020

Nov. 26, 2020

I have continued to work slowly on this project. Named pipes are supported, the samba client can connect and list available shares. i am currently working on a vfs layer using deferToThread to provide asynchronous file access I have tried to keep the code divided into logically separate chunks . my first chunk received comments from glyph 2 months ago but has remained in the review queue since. https://twistedmatrix.com/trac/ticket/9818 is there anyone available to review this code to progress it ?

[Twisted-Python] twisted vs asyncio vs tornado (and other event loops?)
by Chris Withers Nov. 25, 2020

Nov. 25, 2020

Hi All, Just bumped into Glyph's post from last year: https://twistedmatrix.com/pipermail/twisted-python/2019-April/032280.html Doesn't look like there was much of a response, so wondered what had happened with the plans laid out? Also interested in how people see crochet fitting into this world... cheers, Chris
