I wrote my problem in the last message an I wasn't clear with that... Ok... I'm going again... !!! I have a web server... this server was implemented with twisted using XMLRPC... when the server start to run, in this moment I did "reactor.run()"... well, my server is listening by 8080 port, and when one command had become, I catch the command, interpret it, and after I need to run another process tu execute the command. To execute another process I have to call "reactor.spawnProcess(...)" with its parameters, and after I have to say again "reactor.run()", but the reactor is running because the server isn't stop. I need to run another process with twisted without reactor.... how can I do that ?? or, I can do the same thing with another variant ??? please.... help me !!! ------- [Tank] "Amar desenfrenadamente es abrazar la utopía de que tenemos lo que queremos." ------- Freddy Martinez Garcia Lic. en Ciencia de la Computación.

[Twisted-Python] How to detect when there is nothing waiting in the event queue
by Mark Visser 15 Sep '09

15 Sep '09

Hi, we've been using Twisted in an internal project for the past 4 months. It's a system that polls for events from a web source (looping call) and also accepts connections via perspective broker. Each of these events is turned into a series of Deferreds that run various tasks. Some of these tasks are long-running and can take several hours to complete. Because of this, it's very difficult to restart the server when we roll out a new release. I've added a signal handler to catch SIGHUP and call stop() on the looping call and stopListening() on the perspective broker Root. How can I detect when all remaining Deferreds have fired so I can stop the reactor safely, without stranding any running processes? thanks -- Mark Visser, Software Director Lumière VFX Email: markv(a)lumierevfx.com Phone: +1-514-316-1080 x3030

Hi Alexandre: >Do you guys know anyone using or developing Twisted in the area around >the city of Montreal? I live in Montreal and I use Twisted. >I also go to Montreal Python from time to time, and I think Twisted >would make a good special topic to cover. It would help converting >more developers to it. See http://montrealpython.org/ I will be giving a talk on Stackless Python on September 30th, as a part of Montreal Python. In a section of that talk, I will briefly touch on Twisted. Cheers, Andrew

[Twisted-Python] sftp with Twisted
by gslindstrom＠gmail.com 11 Sep '09

11 Sep '09

I am new to Twisted but have read through the Twisted Book (O'Reilley) and worked many of the examples. I think I have deferreds down (though I'm not sure I understand the red/green diagram, yet :-). I'm running Python 2.4 on Gentoo Linux. We would like to look into using Twisted for sftp. Looking through the "conch" routines I found the test_filetransfer.py. I see lots of classes, "Avitars" and tests but I can't figure out what everything is doing or how to connect to a box (using either a username/password of a key) and transfer files! Is there a "how-to" showing, well..., how to set up and use sftp with Twisted? If not, I'd be willing to write one up if someone would volunteer to mentor me through the process. Thanks for your help, --greg
