[Twisted-Python] sniffing multicast traffic
by Ben Barker 10 Mar '10

10 Mar '10

Hello - I wonder if someone can help: We have some status info being sent by various machines using multicast addressed udp packets. I have been attempting to use twisted to write a python script that will passively monitor on the relevant port for any udp packets with the specified multicast address, which I can then parse the payloads of as required. I have been looking at the examples here: http://code.activestate.com/recipes/425975-simple-udp-multicast-client-serv… But I seem to have trouble getting them to receive anything at all. I have managed to use tshark to display the packets : tshark -i eth0 -x -l -f udp so I know the data is there (coming isn on address 224.0.0.4, port 901) Any suggestions? B

While I see tickets in the tracker for web2 and others for web, I couldn't find a 'cherry pick' list of things to be moved from web2 back into web. Is there one? Thanks, S

[Twisted-Python] Get Twisted 10.0 in to Ubuntu 10.04 LTS
by Jonathan Lange 09 Mar '10

09 Mar '10

Hello all, Ubuntu's "Lucid Lynx" is now in feature freeze, meaning that it won't automatically take new versions of packages (see https://wiki.ubuntu.com/FeatureFreeze). Since we've just released Twisted 10.0.0 and since the release is awesome, stable, low-risk and a great thing to have in the next long-term support version of Ubuntu, I think we should strive to get a "Feature Freeze expection" (aka an "FFe"). I've followed the https://wiki.ubuntu.com/FreezeExceptionProcess and have filed a bug at https://bugs.edge.launchpad.net/ubuntu/+source/twisted/+bug/531977. But I need help. The FFe process requires a packaged version of the new release, along with build files and what not. I lack the expertise to do this, so I'd very much appreciate it if someone here who knows Debian/Ubuntu packaging could please package the new 10.0.0 release and attach the relevant files to the bug. Thanks, jml

[Twisted-Python] How to use time-base event in reactor?
by sleepd 08 Mar '10

08 Mar '10

I am developing a online RTS game server, some event a base by time, example: a buff grant Max HP for 30 seconds, spawn army ever 30 seconds... I plan to use a timer to manage it, but Twisted are event-driven, how to put this timer in reactor's loop?

[Twisted-Python] Synchronous byte streaming
by Darren Govoni 07 Mar '10

07 Mar '10

Hi, I received some great advice in the past about using Int32StringReceiver to be able to send a reliable message of bytes from the client to the server without hassling with unordered or partial messages. Seems to work. But I have one problem. My client iterates over a file sending 7MB byte messages to transport.sendString() to a server. What i see is that the client seems to buffer or wait to send those. After a few hundred sendStrings() still the server has not received one message. The result is my client gets throttled bad in terms of disk and memory. After all my sendString writes, then eventually the server receives the first message. But my computer is 100% max'd out. highly undesirable. What I want is for each on-the-wire send to complete, before sendString returns so resources can be managed properly. Is there _any_ way in Twisted to do this? thanks for any tips!! Darren

[Twisted-Python] 10.0.0 post-release actions
by Jonathan Lange 06 Mar '10

06 Mar '10

Hello all, 10.0.0 is well-and-truly released. Jean-Paul has just updated the website documentation and I've made notes on what he did and stored it at http://twistedmatrix.com/trac/wiki/ReleaseProcess. My plan now is this: * Roll out a 10.0.1 release * Give ReleaseProcess a lot of love, turning it into a readable, useful document rather than a bunch of raw data * Make sure tickets are filed on all of the hard bits of the process * Schedule a 10.1 release * Fix the tickets that made the process hard * Do the 10.1 release * Find someone willing to be release manager for 10.2 and 10.3 Regarding the 10.0.1 release. The milestone[1] has two open tickets, one of which has a patch sans tests, and the other is mostly minor defects. I will try to roll out a 10.0.1 release soon that fixes both of these issues. There is also an open ticket which *might* be a regression: http://twistedmatrix.com/trac/ticket/4351. What you can do to help: * Investigate #4351 and decide whether or not it's a regression * Land a patch for http://twistedmatrix.com/trac/ticket/4210 * Fix tickets on the regular-releases milestone[2] cheers, jml [1] http://twistedmatrix.com/trac/query?status=new&status=assigned&status=reope… [2] http://twistedmatrix.com/trac/query?status=new&status=assigned&status=reope…
