[Twisted-Python] Need advice on changing blocking calls to be Twisted-aware...
by Stuart Hungerford May 20, 2003

May 20, 2003

Hi all, I'm running a web application which makes use of the excellent Twisted.Web resource framework with customized .getChild() and .render() calls. In one of the resource .render() methods I've reached a point where the method needs some information on from the system via an os.popen2() call. This information is needed to be turned into HTML, and the HTML generation can't proceed without it. What I'm effectively doing in the render() call is: def render(...) ...… [View More]

[Twisted-Python] Twisted and SQL-Ledger
by pobrien＠orbtech.com May 19, 2003

May 19, 2003

I'm going to be creating a Twisted Woven/Enterprise interface for SQL-Ledger, an Open Source accounting package that uses PostgreSQL and a Perl web interface. Is anyone else interested in such a thing? SQL-Ledger: http://www.sql-ledger.org/ -- Patrick K.

[Twisted-Python] splitting log file
by Philippe Lafoucrière May 19, 2003

May 19, 2003

Hello I've made a server using PB and woven (both are running in main server). When I do some very long calculations, the log file is splitted in several parts (977K). Moreover, web log is mixed with PB log, which hard to debug. Is there a way to correct these two problems ? thx Philippe

[Twisted-Python] Interrupted system call in Twisted.Web...
by Stuart Hungerford May 19, 2003

May 19, 2003

Hi all, My application is happily using Twisted.Web for a web interface to a set of resources. At one point I'm doing an os.popen2() call to find some details on a particular resource. For now at least using the popen2() call is the only way I can get this information. Occasionally I'm getting an "Interrupted system call" Python exception from this call. I'd guess that os.popen2() is not especially friendly to an asynchronous processing model like that used in Twisted? Could someone point … [View More]

[Twisted-Python] Named Pipes
by Wari Wahab May 17, 2003

May 17, 2003

Hi, is there a way to get twisted to listen to a named pipe like it's a TCP connection or something? How would I go about it? What I wanted goes like this, there's a named piped, and syslog or other programs can send one line alerts (or multiline as well), and my app is supposed to do something with this data while attending to other stuff as well. We have a perl program that does this using select(), and I bet this can be done with twisted. But I don't see a named pipe implementation in … [View More]

[Twisted-Python] twisted.web.woven.guard.SessionWrapper problems
by Matthias Urlichs May 16, 2003

May 16, 2003

I was experimenting with twisted.web.woven.guard yesterday and ran into a problem. Some browsers, including wget, don't like _at_all_ when you have a cycle in your redirections, even though they should notice that they now have a cookie while formerly they didn't. Therefore I propose to rewrite the SessionWrapper to always change the user's path, like this (the string "sp" is self.cookieKey): /sessionized-url/foo Set cookie Redirect to /sessionized-url/sp__aef9c34aecc3d9148/foo /… [View More]

Hi, something strange shows up here. I try to create a TAP from a pb application. The tap is created nicely, but I get an error when starting it: Failed to load application: <twisted.persisted.styles.Ephemeral instance at 0x82450a4> is not safe for unpickling So I tried a simple application and took the echoer from the manual. from twisted.spread import pb from twisted.internet import app class Echoer(pb.Root): def remote_echo(self,st): print "echo: ",st return … [View More]
