[Twisted-Python] Simple OSCAR Bot
by pokerface 16 Jan '06

16 Jan '06

Greetings, list. I'm attempting to wrap my brain around Twisted for the purposes of creating a simple OSCAR bot. The purpose of this bot will be to send a broadcast announcement to a mutable list of screennames to help with admining gaming servers. Every example I've seen of OSCAR bots has the bot log in and respond to all sorts of messages that it gets sent, staying logeed in the entire time. My needs are simpler; the bot need only log in, send its messages, and log right back out. From what I can suss out, this would still necessitate a connectTCP() call, but it doesn't need a reactor.run(). My trouble is that I don't know exactly what it WOULD require beyond connection (IE, where to put the sendMessage, whether to create callbacks, etc. etc.). I also don't quite know how I would pass different lists to the bot class for the broadcast, but that's a secondary concern that I can work around inefficiently if I have to (I think). If someone knows of some keywords I'm missing for my google search, or if they can otherwise point me in the direction of an example of what I'm attempting to do, I would be most appreciative. Thank you all for your time. Sean

[Twisted-Python] hobart meatspace sprint - the final hurrah
by Tim Stebbing 15 Jan '06

15 Jan '06

We're looking at having a final Hobart AU sprint this Feb, before we Hobartians go our separate ways. This would be on the weekend of the 11th-12th and perhaps a day either side if people are interested. Sprint topics suggested are currently: * Fix VFS (deferred support, move the protocol specific bits into the various parts of twisted, integrate dav) * Trial GUI ? Current meatbag attendees: tjs, radix, cablehead, teratorn, jml? Current virtual attendees: lifeless? Currently thinking about it: spiv, jerub People I have not spoken with yet but would rock if they came: hypatia, elspeth -tjs

Take a look at twisted/names/authority.py and > twisted/names/common.py. The hook you are probably interested in is > the _lookup method Ok. I have to admit I am completely new to twisted... I am also not sure whether I explained myself good in what I want to do... Basically, I need a replacement for /etc/hosts. I have a daemon running on my box, and was thinking about adding a thread to it which could serve as a simple local dns server. Right now, my /etc/hosts gets updated by a cronjob every now and then. The cronjob fetches IP-addresses and hostnames from a firebird DB and writes them to the hosts file. What I was thinking to do with my daemon is, having in memory a list/hashtable of hosts with their IPs. If an IP changes I get a firebird event and I can updated it in my list. Now twisted.names would only have to listen to dns requests (I have e.g. wget and openvpn which want to resolve names from my hosts right now periodically), lookup the IPs of the requested names in my in-memory list of hosts/ips, and answer as a normal dns server. isn't twisted/names/server what I need for that? thanks and best regards, Yves p.s. Is there any more documentation available apart of this: http://twistedmatrix.com/projects/names/ http://twistedmatrix.com/projects/names/documentation/howto/names.html > Jean-Paul

[Twisted-Python] Repeatedly calling Deferred.callback()
by Brian Granger 13 Jan '06

13 Jan '06

Hi, Are Deferred objects designed to have their callback method called multiple times it there are a multiple (discrete) results that arrive asynchronously? If not, what is the proper construct in Twisted for returning multiple asynchronous results from a single method? Thanks Brian

[Twisted-Python] Documentation virtual sprint: 14th January
by Mary Gardiner 12 Jan '06

12 Jan '06

Hi all, A reminder to interested parties that I set the date for this to this coming Saturday: 14th January. What follows is a reminder about what I want to do. I'll set up something more specific for this in a day or two. I envisage I'll have a worklist of some kind on a wiki, and that participants will also be chatting on #twisted as usual to resolve anything else. -Mary ----- Forwarded message from Mary Gardiner <mary-twisted(a)puzzling.org> ----- I'd like to run a one day Twisted documentation sprint. Please note that while I want and need input from both Twisted experts and Twisted newbies, I won't have much tolerance for general whining about the state of Twisted documentation. (Not that I've ever exhibited much tolerance of this kind.) We need highly specific whining! This sprint will hopefully be the first in a series, and it will be focussed on *reading* the documentation, rather than writing it. We would therefore especially welcome the input of people who are either users of the documentation, or want the documentation improved but don't want to write it. We will focus on reviewing present documentation against the following criteria: - does it reflect best practices for Twisted coders? - is it up-to-date? - is it complete? For people who are newer to Twisted, reviews on the general useability of any particular piece of Twisted documentation as per my post at http://twistedmatrix.com/pipermail/twisted-python/2005-May/010386.html ----- End forwarded message ----- -- <dash> your RDF is massive and unstoppable.

[Twisted-Python] mixing a Cacheable and a Viewable
by Forest Darling 10 Jan '06

10 Jan '06

I want to make a server side object that the client can access via a RemoteCache, but also access view_ functions from the Cacheable via .callRemote() This way a player can see an object based on its perpective (like fog of war) and a player can also call server-side methods for game actions (like to move a hero.) from the server and remote classes trying to inherit both doesn't work, so how do I do this? This kind of problem must have come up before... Heres the link to my non-working partially done code, the Game, Player, and Hero classes need to behave this way. Heres a copy of my source, it needs Numeric, PyQt, and of course Twisted http://behemoth.binarypimpin.com/~forest/pyhomm/files/PyHoMM-broken.zip

[Twisted-Python] slightly silly hack
by zooko＠zooko.com 09 Jan '06

09 Jan '06

Ever wanted to execute your trial tests as though they were commands? You can use tab completion in bash, for example: $ ./amdlib/storage/test/test_storefile.py -s It's easy! Give your file executable permission and at the top of the file type this line: "#!/usr/bin/env python". At the bottom type: """ if __name__ == "__main__": import os, sys mods = [] fullname = os.path.realpath(os.path.abspath(__file__)) for pathel in sys.path: fullnameofpathel = os.path.realpath(os.path.abspath(pathel)) if fullname.startswith(fullnameofpathel): relname = fullname[len(fullnameofpathel):] mod = (os.path.splitext(relname)[0]).replace(os.sep, '.').strip('.') mods.append(mod) mods.sort(cmp=lambda x, y: cmp(len(x), len(y))) mods.reverse() for mod in mods: cmdstr = "trial %s %s" % (' '.join(sys.argv[1:]), mod,) print cmdstr if os.system(cmdstr) == 0: break """ Regards, Zooko
