[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. ______ __ __ _____ _ _ | ____ | \_/ |_____] |_____| |… [View More]

[Twisted-Python] Many connections and TIME_WAIT
by Donal McMullan Feb. 22, 2010

Feb. 22, 2010

I've been prototyping a client that connects to thousands of servers and calls some method. It's not real important to me at this stage whether that's via xmlrpc, perspective broker, or something else. What seems to happen on the client machine is that each network connection that gets opened and then closed goes into a TIME_WAIT state, and eventually there are so many connections in that state that it's impossible to create any more. I'm keeping an eye on the output of netstat -an | wc -l … [View More]

[Twisted-Python] How to diagnose slowness
by Gabriel Rossetti Jan. 26, 2010

Jan. 26, 2010

Hello everyone, I have noticed slowness sometimes in between two twisted apps. It doesn't happen often, and I'm not sure where it comes from. It may either be when the msg is sent, that it really isn't sent until after a delay (why?), or when the other service receives it, it takes time to process the msg. The second idea may be easier to find, I haven't been able to though. If I send the same msg, sometimes it's slowed down, and sometimes not. From what I see both of my suggestions may … [View More]

[Twisted-Python] upload and receive
by Raj kumar Jan. 25, 2010

Jan. 25, 2010

Hi, Currently I'm using twisted.web api for my http server. If I have to implement a file upload from client, is it possible to receive a file at server end using twisted.web? or should I move to twisted.web2? but I read twisted.web2 is not stable(that too, I may have to change my code for a shift). Any sample references (using twisted.web api) to receive a file from client is appreciated. Thanks in advance. Raj. The INTERNET now has a personality. YOURS! See your Yahoo!

[Twisted-Python] Kajongg - a new game base on PyQt and twisted

The GUI is done with PyQt4, and the network part is written using twisted.

Hello eveyone, I think it is nice to mention this announce here, since Purity heavily uses Twisted. (as well all my other Python projects, such as Toonloop, and others) Purity is a Python library for Pure Data dynamic patching. The idea is to be able to harness the power of Pure Data for audio programming without having to use its graphical interface, and without the need to create external objects in C. Python's clear and intuitive syntax can be used with profit in order to create intricate … [View More]

Then it prints the following traceback: terekhov@linux:/home/terekhov/python/twisted/9.0/Twisted-9.0.0/doc/names/examples >python gethostbyname.py localhost 127.0.0.1 ^CUnhandled error … [View More]

[Twisted-Python] SIP and RTP

Hello, I need to make a SIP call and play a wav file over the RTP stream from a twisted server. This is a sort of visual voicemail application. Has anyone set this up using twisted before? I saw the SIP protocol support in twisted, but I'm not sure how complete it is. Do you think it would be difficult to make this solution a reality? I heard of the Shtoom project which did this using Twisted, but it appears dead I can't find the source code for it.

[Twisted-Python] Lore to Sphinx Conversion Progress Report 4
by Kevin Horn Jan. 21, 2010

Jan. 21, 2010

This time I think I'm gonna skip saying how I haven't gotten as much done as I would like...oh darn. Anyways, time for another gripping installment... Progress: - tables are now handled (mostly) properly, thanks to Zeth at http://commandline.org.uk/ - blockquote tags handled - much improved whitespace/indentation handling - some nicer styling thanks to Michael Thompson - I've managed to convert the docs for the 3 Divmod projects with Lore docs, though I've yet to put them up … [View More]anywhere. Oustanding issues: - two files in the Lore source are not yet being converted, but it looks like one of them is about to be removed (http://twistedmatrix.com/trac/ticket/4188), and it's not really a Lore doc anyways. - due to ReST's insistence on "inline markup" being surrounded by whitespace or certain special characters, there are a lot of places where such inline markup gets jacked up, by not including whitespace in front of it. If I put whitespace in front of everything though, my indentation handling gets jacked up and about 400+ Sphinx build warning result. Not sure if I should spend the time to make whitespace handling really smart or if these should just be fixed manually post-conversion. - cite tags still need handling...not hard, just haven't decided the best way to do it yet. - Themeing/styling: still mostly a TODO, though new styling looks a lot better than the default to my eyes. I'm starting to think that eventually we might want to have 2 themes/styles...one to match the trac-based website, and one for bundled docs (docs tarballs, CHM files, etc.) - auto-generated toctree directives are currently generated in alphabetical order, which makes the "prev" and "next" links mostly make no sense - some of the Lore source files have nested "inline markup", which ReST disallows. This can be handled by: - fix the markup in the Lore source - figure out some kind of supersmart auto-conversion for every possible combination of nesting - just handle the outside level of nesting (what I'm doing now) and fix any problems manually post-conversion. - xhtml entities are not currently resolved...mostly because it makes the build take a LOOOONG time. They can be though. This shouldn't be a problem. - xhtml comments still need to be handled - <code class="API"> tags need something better..right now they are just the same as <code> tags...Sphinx has an upcoming feature coming in 1.0 that would make this nice and maintainable in the long run, but I don't know that I want to wait for it. I may try to "backport" the extension or just come up with a separate solution. - some of the generated links need fixing (e.g. links to directories, .py files) In other news: - Foolscap 0.5 was released today, which made me wonder what they use for docs...and it's Lore. I brought this up on IRC, and it was suggested by many that Lore should stick around even after the conversion according to the standard Twisted compatibility policy, to give anyone who still uses it time to migrate. This sounds like a fine idea to me. Any thoughts? As always, the lore2sphinx code is here: http://bitbucket.org/khorn/lore2sphinx/ And the sample output of the conversion process is here: http://twistedsphinx.funsize.net/ Cheers, Kevin Horn [View Less]

Hi all I know this has been discussed numerous times, but I need some extra help. I have used nose.twistedtools' @deferred decorator to run the reactor within a test method to date. Now I am writing some performance tests for our application and need better control over the reactor. nose has threaded_reactor() and reactor_stop() to control things, but regardless, it still doesn't seem to shut down. I need to shut down the reactor between tests so that requests are dropped (ie get a real … [View More]
