[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] flash's rtmp protocol
by Douglas Bagnall Jan. 9, 2004

Jan. 9, 2004

RTMP is a secret protocol used by Macromedia flash servers to do fancy interactive/streaming stuff. I found a reference to it on one of Bob Ippolito's TODO lists: http://pythonmac.org/wiki/BobIppolito "TODO: [....] Reverse engineer proprietary RTMP protocol (Flash Communication Server) and implement Python version (Twisted)" I'm also interested in doing this, but am unlikely to start soon. So this is just to let you (Bob) know, lest we do too much in parallel. douglas

[Twisted-Python] Twisted Weekly News #10
by Luc Stepniewski Jan. 6, 2004

Jan. 6, 2004

==================================================================== Twisted Weekly News #10 ==================================================================== .. contents:: There wasn't too much mail this week, so I merged the previous TWN with the current, as I was ill last week. If you have any new information, ideas, announcements for the next TWN, please write to me, <lior(a)gradstein.info>. TWN is also available as HTML formated ReST on http://gradstein.info/articles/ … [View More]twisted_news/twisted_news/twn10 The Twisted Weekly News ------------------------- 9&10th Issue. Sunday, December 28, 2003 QOTW:: http://twistedmatrix.com/pipermail/twisted-python/2003-December/006789.html From a mail by Alan McIntyre: "I just wanted to thank the Twisted developers for making such a cool piece of software. [...] Thanks to Twisted and Python, I was able to start from scratch and put together a server to present some of this data via XML-RPC in about 2 or 3 hours (and that includes looking up a lot of stuff in the documentation)." Discussions ------------- * http://twistedmatrix.com/pipermail/ twisted-python/2003-December/006786.html Jonathan Simms asked for help on his new (new) ftp server code which is currently in sandbox. He asks for help to resolve some problems with authentication on the Windows side. * http://twistedmatrix.com/pipermail/ twisted-python/2003-December/006828.html More and more people are becoming interested in integrating Twisted stuff into their projects. Last week, RodrigB asked about The Circle. This week, Valentino Volonghi asks about the possibility (wish) to replace the pygame event loop with a Twisted reactor. * http://twistedmatrix.com/pipermail/ twisted-python/2003-December/006820.html Michal Pasternak made some tests on Twisted, and noticed some performance degradation after 40 simultaneous connections. Itamar replied there wasn't anything hardcoded that would change Twisted behaviour above 40 simultaneous connections. Cool Thing of the Week ----------------------- * **Treasure of code examples and tutorials for nevow** (http:// www.livejournal.com/users/fzzzy/) fzZzy updated his new blog on LiveJournal with a lot of code samples he wrote for people who asked questions on irc. The second lecture he gave on irc is also available (http://soundfarmer.com/content/logs/ NevowLecture2-121503.txt). With these docs and the previous more "in-depth" documentation from justinj (http://stewstuff.com/doc/nevow.xhtml) you do not any excuse for not learning nevow! * **SFTP support in Zope (using Twisted!)** (http://twistedmatrix.com/ pipermail/twisted-python/2003-December/006839.html) Fred L. Drake, Jr. wrote some support (http://cvs.zope.org/Packages/ SFTPGateway/) for the sftp protocol to be included in Zope. The result may be available as a separate product in a near future. * **Impacket** (http://oss.corest.com/projects/impacket.html) Not related to Twisted, but interesting anyway.Itamar recommended us to take a look at this python library which provides low-level programmatic access to network packets (tcp, udp, etc.). There is also a python pcap implementation on their web site. * **Reminder about the web forum** (http://twisted.banquise.org/) May I remind you that a web interface exists for those that prefer reading informations online? We're barely 8 now, but nobody posts anything which can be discussed :-( Current releases ----------------- * Twisted: 1.1.1 (released 2003-12-10) * Quotient: 0.8.8 (released 2003-12-12) * Twisted Java: 0.6.1 Ok, that's it for this week. Thanks for reading! [View Less]

[Twisted-Python] Subversion
by Itamar Shtull-Trauring Jan. 1, 2004

Jan. 1, 2004

Currently in beta. Atomic commits, real support for renames, folders, etc.. Can do both anon and logged in access without apache (ssh and pserver style). Has emacs mode. Has windows clients (e.g. TortoiseSVN, VS.NET integration). Has cvs importer. viewcvs supports it. I say we switch when it hits 1.0. -- Itamar Shtull-Trauring http://itamarst.org Looking for a job: http://itamarst.org/resume.html

[Twisted-Python] Re: [Twisted-commits] log stderr and non-zero exit code in CGIs, don't show info to users as it is a security risk (closes issue #241)

If it's a security risk, provide a way for the server administrator to turn it off, but this is a _bad_ default. If you doubt the wisdom of making this default, please consult any number of Perl FAQs of the form: Q. "I wrote a CGI and it works perfectly, … [View More]

[Twisted-Python] Recovering PB references on broken connection?
by David Bolen Dec. 30, 2003

Dec. 30, 2003

I've been experimenting with the perspective broker in Twisted 1.1.0 and am wondering? Is there any graceful way to reconnect and continue to use PB references if you temporarily lose a connection due to a network outage? For example, I can envision my application as being a client that connects to a remote application server, and while running may have any number of PB references to that remote application server in various data structures in the client. Should there be a transient network … [View More]

[Twisted-Python] Unjellying per broker vs. global jelly.unjellyableRegistry
by Ralf Schmitt Dec. 28, 2003

Dec. 28, 2003

Hi, I have attached a patch, which makes it possible to unjelly different classes depending on the broker they were sent through (basically one can set a brokers 'unjellyableRegistry' attribute, which then get's used instead of the global one). Has such a feature already been planned?

[Twisted-Python] .tac filenames configurations

Dec. 27, 2003

Is there a way to indicate in the .tac file which .log and .pid filenames the .tap file will generate ? If not, should not this feature be aviable ? Happy new year for the Twisted minds... RodrigoB.
