[Twisted-Python] How many threads in an application
by Christian Schneider May 23, 2006

May 23, 2006

Hi all, I have implemented a server as a subclass of t.i.TCPServer and have it running as a twistd application. Within the service, I have several callbacks. Let's say I have three connected protocols, how many threads to I have? Just one or more. The callbacks are scheduled via reactor.callLater. Thanks, chris

[Twisted-Python] [ANN] pglib 0.1
by Manlio Perillo May 23, 2006

May 23, 2006

I'm pleasant to announce the first public release of pglib. pglib is an implementation of the PostgreSQL protocol, version 3.0. It is written in Twisted, and aims to be a complete replacement for libpq. In the current version the extended query sub protocol is not supported. The project can be found at: http://developer.berlios.de/projects/pglib/ Subversion access coming soon. Unfortunately, I still have to write some documentation/examples. However there is a (hopefully) detailed README … [View More]

[Twisted-Python] Problems with spawnProcess on Windows with ActiveState's ActivePython 2.3
by christian simms May 23, 2006

May 23, 2006

I see this is a known problem (issue #1457 is closed, link at http://twistedmatrix.com/trac/ticket/1457), and the solution is to upgrade your pywin32. However, it's annoying that the current latest ActivePython 2.3 still includes the old and buggy pywin32 -- ActiveState's release notes at http://aspn.activestate.com/ASPN/docs/ActivePython/2.3/relnotes.html state that they are including build 203+ (20050128). As a simple solution, I wonder if someone could add a line to the Trac download link … [View More]

[Twisted-Python] Twisted to proxy php out to apache?
by Remi Cool May 23, 2006

May 23, 2006

Hello fellow twisters, We have a rather large web app based on xul, xmlrpc (via twisted) and php (via apache) .... and we would like to get it all (in due time) in python. As a first step it would be perfect to let twisted handle php page requests so that we can use nevow for the upcomming modules and convert old modules when we have the time to spare. Some time ago, I tried to get PHP to run as a CGI from twisted ... that was so slow that I got timing problems and a non operatable webapp. … [View More]

Serialization is CPU- and > memory-intensive. Well, the memory footprint is equal to the size of the chunk that you're paging.. that's the reason for using FilePager, to reduce the chunk size. (I think the instantaneous footprint is 2x the chunksize, but once the chunk has been serialized, … [View More]

[Twisted-Python] Calling deferred within a callback, good or bad idea ?
by Stéphane Brault May 21, 2006

May 21, 2006

Hi, I have to call a web service then process the answer, according to the answer I may have to call the service again. The traditional way to go would be : condition = 1 while condition: message = callWebService() condition = processMessage(message) Here is what I do : def function(): def myCalback(message): condition = processMessage(message) if condition: deferred = callWebService() deferred.addCallback(myCallback) … [View More]

[Twisted-Python] Bugs, bugs, bugs
by Jonathan Lange May 21, 2006

May 21, 2006

Hello, In the interests of household cleanliness[1], I propose we have schedule a weekend of bug squashing. We currently have six hundred and five active tickets. Apart from scheduling a time, and maybe creating a wiki page, I'm not really sure how these things work. I suggest June 3-4 as a good time, as that will match with the sprint in Sydney. What do you reckon? jml [1] http://www.advogato.org/article/215.html
