[Twisted-Python] Twisted Python 0.7.0 Prerelease Testing
by Glyph Lefkowitz Aug. 5, 2021

Aug. 5, 2021

hi there, folks: I'd really like to release 0.7.0 but I would like it to be at least a little bit tested before I do so. Could those of you with CVS trees check everything out and see if it performs as advertised? Deeper bugs than that will have to wait for the next release, but I'd at least like to know if it works for someone other than me. Thanks. ______ __ __ _____ _ _ | ____ | \_/ |_____] |_____| |… [View More]

[Twisted-Python] Problem: spawnProcess() never ending when installSignalHandlers=False
by Matt Feifarek Feb. 3, 2007

Feb. 3, 2007

Hello. I'm using Twisted 1.3.0 on python2.4 on an Ubuntu-Hoary x86 Linux box. I'm using twisted and spawnProcess() with a Queue structure to chain processes that need to be called (specifically, imagemagick commands). I use the "processEnded" event/method of t.i.p.ProcessProtocol to go from one task to the next. Twisted shares a python process with a multi-threaded web-app-kit (Webware) so it has to be run in a thread. This worked well on other older versions of twisted and older versions of … [View More]

[Twisted-Python] Traceback from pb-Server

Sept. 6, 2005

Hi, Please excuse my bad english, I hope you will understand what I mean, otherwise feel free to ask. I'm trying to get error messages from my server. I'm using twisted 2.0.0 with python 2.4. The server looks like this: from twisted.spread import pb from twisted.internet import reactor, threads class ServerObject(pb.Root): #...some other methods, which aren't involved... def remote_fitness(self, task, taskDescription, serverID): return threads.deferToThread(self.calc, task, serverID, … [View More]

[Twisted-Python] Errors after upgrading to 2.0.1
by snacktime July 31, 2005

July 31, 2005

I'm testing out an application I wrote in 1.3. In 2.0.1 I get a warning and an exception. The UserWarning about SSL I looked up on the list and I understand why it's there, although I think it's a bad idea. The warning is about a bug in pyopenssl that hasn't been fixed in pyopenssl. In addition there is no reason to think it will ever be fixed after being ignored for this long. Maybe someone could find a better solution for this warning other then leaving it to end user to find the patch … [View More]on the mailing list, which for all I know might not even work at this point. Maybe put up a patched copy of pyopenssl on twistedmatrix.com? Seems better than having an unmaintained dependancy in twisted. The exception I really have no clue about, maybe someone could point out where the problem is?

[Twisted-Python] PB checkers bug?
by Steve Freitas July 28, 2005

July 28, 2005

Hi all, I didn't get a reply to my earlier post about inventing mad crazy checkers, so I decided to just use the IUsernamePassword interface, but I'm stuck, because it appears PB won't allow me to use only that interface. If I try, it dies like this: Traceback (most recent call last): Failure: twisted.cred.error.UnhandledCredentials: No checker for twisted.cred.credentials.IUsernameHashedPassword, twisted.spread.pb.IUsernameMD5Password, twisted.spread.interfaces.IJellyable To reproduce the … [View More]

[Twisted-Python] CPU intensive threads
by Nathaniel Haggard July 27, 2005

July 27, 2005

Is there anything twisted can do about CPU intensive threads? When I run a CPU intensive method via threads.deferToThread it takes all the CPU away and renders the twisted process unresponsive. The perspective broker for example will not make any connections until the CPU intensive methods finish. Is there a way to set the priority of the main part of twisted so that it can run CPU intensive threads and still service connections. Thanks, Nate

[Twisted-Python] Getting peer IP address from Perspective Broker
by J French July 26, 2005

July 26, 2005

Is there an accessible method to retrieve a peer's ip address from within pb? I just want to log it. I read the Faq and see how to do it when subclassing protocol i.e.: class MyProtocol(protocol.Protocol): def connectionMade(self): print "connection from", self.transport.getPeer() I'd appreciate it if someone can point me in the right direction. TIA
