[Twisted-Python] raw deferreds vs deferredGenerator vs inlineCallbacks
by Marcin Kasperski Aug. 13, 2008

Aug. 13, 2008

I wrote a short example comparing the 3. Prepared it mostly for myself, but maybe it will be of some use for somebody: http://blog.mekk.waw.pl/archives/14-Twisted-inlineCallbacks-and-deferredGen… PS Crucial function: raw deferreds - 29 non-empty lines of code, deferredGenerator - 26 lines, inlineCallbacks - 17 lines -- ---------------------------------------------------------------------- | Marcin Kasperski | Systems built by humans are always subject | http://mekk.waw.pl | … [View More]

[Twisted-Python] AsynQueue: return deferred from queued method
by Stephan Jaeger Aug. 12, 2008

Aug. 12, 2008

Hello List, I'm trying to use AsynQueue for queuing requests for a synchronous protocol (emi/ucp). Is it possible to return a deferred from the queued method so the next method in the queue is only called after the deferred from the first was fired? Or is there a better way to handle synchronous protocols where i have to wait for an answer of a message sent over the wire before i can send another one? Thanks, Stephan

[Twisted-Python] does setTcpNoDelay() not work?
by Gabriel Rossetti Aug. 12, 2008

Aug. 12, 2008

Hello, I'm needing to send small packets to update a progress bar. My update msgs were all being sent in big packets, so I tried setting setTcpNoDelay() in connectionMade() but it doesn't change anything, is it broken? Thank you, Gabriel

ciao! i'm playing a bit with foolscap and i try to use RemoteInterface to describe my constraint but i cannot understand how to use it with pass-by-copy. this is a small example: from foolscap import RemoteInterface, registerCopier, \ registerRemoteCopyFactory class Label: def __init__(self, text): self.text = text def copyLabel(label): return ('_Label', {'text': label.text}) registerCopier(Label, copyLabel) def makeLabel(state):… [View More]

[Twisted-Python] Jython reactor - a proposal
by Alan Franzoni Aug. 9, 2008

Aug. 9, 2008

Hello everybody, I recently took a look at the current Jython status, and it seems to me that the latest alpha provides a good compatibility towards the standard CPython. I'd really like running jython+twisted, so when I realized there was no reactor available for such platform I took some time to analyze the issue: - An old-and-incomplete java reactor existed in Twisted 1.3 which used java.io. - java.nio would be a better choice to implement such a reactor since java 1.4 - a wrapper around … [View More]

Aug. 8, 2008

Hi list, I'm currently in the process of hacking together TIPC[1] support for Twisted. I've got reliable datagram support in a "works for me" state now. Is anyone interested to see this in Twisted? Thought I'd rather ask here before opening a ticket etc. peter. [1] http://tipc.sourceforge.net/

[Twisted-Python] Permanent Object
by Squzer Crawler Aug. 5, 2008

Aug. 5, 2008

I want to create a server in twisted that has a permanent variable which i want to use as the number of request requested to the server. When i use that for Protocol, each time the variable is created newly. Then i used *class Echo(Protocol): def dataReceived(self, data): if "data" not in dir(self.factory): self.factory.data = 0 self.factory.data = self.factory.data + 1 """As soon as any data is received, write it back.""" self.transport.write(… [View More]
