[Twisted-Python] Multiple delimiters in linereceiver
by Michael Mata Nov. 29, 2004

Nov. 29, 2004

Is it possible to use the LineReceiver protocol with multiple delimiters? I've run into situations where clients use either '\r\n' or a '\n'. To handle either situation, I set the delimiter as '\n' and just filter out the '\r' from lineReceived(). This fix works, but it sure is ugly. Has anyone run into a more elegant solution?

[Twisted-Python] tm.com website
by Mary Gardiner Nov. 29, 2004

Nov. 29, 2004

Just in case anyone wants to release 2.0 before the 28th... I'm going to be pretty much afk for the next two weeks (as will be Andrew, btw), so I won't be, for example, contactable about the website. I've got a nearly complete (well, suitable at least) 2.0 website in a branch in the TwistedWebsite svn repository. The major missing thing is websites for some of the projects. The major thing you would need to take note of when merging would be that I've essentially removed the /products directory. A list of redirects is present in HTML comments in the main index.html file in that branch. -Mary

Some of the signal-handling code was trying to setup a SIGKILL handler, which is an error at the C level but wasn't reported at the python level until 2.4. The tests are running again, 3 failures and 9 errors, all in test_trial. Sample attached.

[Twisted-Python] twistd profiling
by Roland Hedberg Nov. 26, 2004

Nov. 26, 2004

Hi! Need to profile a twisted based application, way too slow ! twistd -p <file> produces profiling data in the named file If hotshot is available it's used ? Are there any nice tools for viewing profiling data ? Since it's the system that is slow and it contains several separate servers I'd also would like to have timestamps on events (preferably with a subsecond resolution) so I could trace flows. How can I ackomplish that ? Any support in twisted for it ? -- Roland

[Twisted-Python] twisted and threading
by twisted-10152003＠atlas.lcs.mit.edu Nov. 26, 2004

Nov. 26, 2004

I wrapped a c library using swig and was hoping to make use of it in a twisted server I am writing. The issue is that the c library fundamentally blocks waiting for input that may never come. Is there a way from twisted to deal with this cleanly within the framework? I.e. some combination of adding a reactor.addSystemEventTrigger event and calling reactor.threadpool.stop seem like it should work but I haven't had any luck yet. (I saw all the previous posts on this topic, but the recommendations don't seem applicable in my case since the blocking is occurring outside my control in a c library and the blocking call may never return.) Thanks, Steve Bauer

[Twisted-Python] XML-RPC, LineReceiver and defer
by Roland Hedberg Nov. 24, 2004

Nov. 24, 2004

Hi! I'm having problems with defer again :-( There is something about defer's that I just don't get, obviously. Anyway, I'd like to get tips on how to solve this problem: I have a module who on one side listens on XML-RPC and on the other uses the LineReceiver protocol to find some information it needs, to service the XML-RFC function. If I have understood it correctly xmlrpc.XMLRFC can return a defer and have the XMLRPC layer hold the reply until some event has happend. Now, the LineReceiver protocol has one function for sending a lines and another function for receiving them. So how do I make XMLRPC wait for the right line. The XML-RPC server should of course be able to handle serveral requests at the same time, so there might be more than one outstanding reply on the lineReceiver side. Knowing which reply that is connected to which sent line is doable by keeping a queue and using IDs ( the protocol on the LineReceiver side, which is no standard protocol, allows for having tags on queries and replies). But how do I keep the connection between the XML-RPC request and the line received ? I though about having defer checking for the change of a value in a dictonary, but I don't know if that is doable, is it ? And finally I don't want to use callLater if I can avoid it. I'd like the performance to be as high as possible. That is, the XMLRPC reply should be sent as soon as the LineReceiver has gotten the reply. I also don't want to setup and tear down a connection on the LineReceiver side for every request that comes in on the XMLRPC side. There is one server on the LineReceiver side that gets all the questions, so I liked to be able to have one connection going. -- Roland

[Twisted-Python] I want to use 2 reactors in same program, help me
by jacky lee Nov. 23, 2004

Nov. 23, 2004

My server used reactor to listen clients's requests. and at client side, I used reactor to connect to server Now I want to use 2 reactors in server side, the server will listen some clients's requests, and it will run a thread to connect to an other server, at the same time
