[Twisted-Python] twisted.mail newbie question
by xing＠mac.com 19 Aug '05

19 Aug '05

Hi all, I have read the twisted.mail.smtp source and ran the sample code (included below) in the debugger with break points and yet I still do not know where I can inject my code to handle actual message delivery where both the email message and all the recipients are available at one point in time. The IMessageDelivery handler doesn't appear to see the message, and the IMessage only sees the message and not the recipients. As such, I'm thorughly confused. Very new to twisted and async programming model. Thanks for any pointers. I have written a basic smtp relayer wrapped around twisted smtp.sendmail using my own delivery queue and mx selection management and trying to put the last piece in: the smtp server which will hand off all incoming messages into my queues. Xing Li code ---------------------------------- from twisted.internet import defer from twisted.protocols import smtp from twisted.internet import reactor class ConsoleMessageDelivery: __implements__ = (smtp.IMessageDelivery) def receivedHeader(self, helo, origin, recipients): for i in recipients: print i return "Received: ConsoleMessageDelivery" def validateFrom(self, helo, origin): # All addresses are accepted return origin def validateTo(self, user): # Only messages directed to the "console" user are accepted. #if user.dest.local == "console": return lambda: ConsoleMessage() #raise smtp.SMTPBadRcpt(user) class ConsoleMessage: __implements__ = (smtp.IMessage,) def __init__(self): self.lines = [] def lineReceived(self, line): self.lines.append(line) def eomReceived(self): print "New message received:" print "\n".join(self.lines) self.lines = None return defer.succeed(None) def connectionLost(self): # There was an error, throw away the stored lines self.lines = None class ConsoleSMTPFactory(smtp.SMTPFactory): def __init__(self, *a, **kw): smtp.SMTPFactory.__init__(self, *a, **kw) self.delivery = ConsoleMessageDelivery() def buildProtocol(self, addr): p = smtp.SMTPFactory.buildProtocol(self, addr) p.delivery = self.delivery return p if __name__ == '__main__': f = ConsoleSMTPFactory() reactor.listenTCP(25, f) reactor.run()

[Twisted-Python] Telnet & echo
by Michał Tyde 19 Aug '05

19 Aug '05

I try to find a solution on google, but nothing I have found there worked in my code. The situation is: I have a telnet client. When I am sending a command to a server my dataReceived loop gets a command I send and response. For example I send a "pwd" command, and in dataReceived i got: pwd /home/user/ I want to have only response. I try to send before sending command IAC WONT ECHO or send command "unset echo" but I have still a command and response in dataReceived. How to shutdown echo?

[Twisted-Python] passing command line args to twistd daemons
by Garry Hodgson 19 Aug '05

19 Aug '05

i've got an application (invoked via: twistd -noy fpc.py) that i'd like to use for multiple purposes by passing command line arguments. when i do so, twistd objects that they are invalid arguments. i'd hoped for some magic arg that partitions the args into twistd arguments and app arguments, something like: twist -noy fpc.py -- -x -y -z but no such luck. so, is there a way to accomplish this? if not, what is the preferred mechanism for customizing an application's behavior at startup time? thanks ---- Garry Hodgson, Technical Consultant, AT&T Labs Your love, your anger, your kindness, your hate.

[Twisted-Python] PEP 342 now in python CVS
by tazzo 18 Aug '05

18 Aug '05

Hi all, referring to the news about the implementation of PEP 342 in python CVS: http://dirtsimple.org/2005/08/pep-342-implementation-now-in-cvs.html I know that is a great news for asynchronous programming in python and for other aspects but I wonder what will be the future of Twisted, what will change (if something will change) in Twisted when PEP 342 will come? I think that with PEP 342 we could write a more readable code but does it mean rewrite all twisted? What is the opinion of Twisted developers?? thanks, Tazzo -- La presente comunicazione potrebbe contenere informazioni riservate e/o protette da segreto professionale ed e' indirizzata esclusivamente ai destinatari della medesima qui indicati.

Hi Thanks for the reply.I need further clarification on Twisted word chat server.Your previous reply to my query mentions that "Twisted word provides a server that is accessible via IRC and PB.And it does support groups and multilanguages." I downloaded the implementation from http://twistedmatrix.com/projects/words/ As such there is no "Twisted Word Chat Server " implementation available here. Could you please suggest that from where can I get the server implementation for it ? Thanks for your time.

[Twisted-Python] problem with combining deferreds together
by michal salaban 15 Aug '05

15 Aug '05

hello all, i've been playing with twisted adbapi for last three days to figure out if it's a goot framework for application that i'm going to write soon. i've stuck on one problem (probably i'm not the first, but couldn't google out the soultion). i have an object, which data is spread between two tables - the MainTable with some data and reference to some row in SubTable with additional things. what i'm trying to do is to create repository class with method .getByID() that takes ID from MainTable and returns deferred, which in callback evaluates to fully instatinated and data-populated object. i've come up to this: class ObjectRepository: def getById(self, id): dMain = self.dbpool.runInteraction( fetchOneAndMapToDictionary, "SELECT * FROM MainTable WHERE id = '%d'" % (id,) ) dMain.addCallback(self._gotMainData) return dMain def _gotMainData(self, mappedRow): dSub = self.dbpool.runInteraction( fetchOneAndMapToDictionary, "SELECT * FROM SubTable WHERE id = '%d'" % (mappedRow['SubID'],) ) dSub.addCallback(self._gotSubData) return [what to return ????] how can i return the result that consist of data from both queries? chaining callbacks is impossible. i cannot have dSub before dMain.callback() is called, and also cannot do dMain.chainDeferred(dSub) in _gotMainData() because dMain has already been returned to calling code and contains callbacks attached there. i suppose the solution is simple, but im 100% newbie to twisted and event-driven programming. thanks in advance :) -- michal salaban -=- emes (at) pld-linux.org -=- jabber: emes(a)jabber.org

Why don't you fetch both in one query (using LEFT JOIN or just WHERE clauses), that would be faster anyway. >class ObjectRepository: > > def getById(self, id): > dMain = self.dbpool.runInteraction( > fetchOneAndMapToDictionary, > "SELECT * FROM MainTable WHERE id = '%d'" % (id,) > ) > dMain.addCallback(self._gotMainData) > return dMain > > def _gotMainData(self, mappedRow): > dSub = self.dbpool.runInteraction( > fetchOneAndMapToDictionary, > "SELECT * FROM SubTable WHERE id = '%d'" % >(mappedRow['SubID'],) > ) > dSub.addCallback(self._gotSubData) > return [what to return ????] > > >how can i return the result that consist of data from both queries? dSub.addCallback(self._gotSubData, mappedRow) return dSub # what else? Just make sure you handle mappedRow in _gotSubData. Or did I miss your point? Best regards, Henning Hraban Ramm Südkurier Medienhaus / MediaPro Support/Admin/Development Dept.

Hi, I am contemplating running XML-RPC over SSL (basically for site to site process communication over the internet). Has anyone got any example code that would point me in the right direction (or just some clues :-) ) cheers mark
