[Twisted-Python] First public release of Flumotion Streaming Media Server
by Thomas Vander Stichele 20 Oct '04

20 Oct '04

Hey everyone, we finally bit the bullet and threw out our firstborn for public consumption. For those not yet in the know, Flumotion is a streaming media server based on GStreamer and Twisted under development by Fluendo. This release gives users access to the basic features of the server and demonstrates its distributed capabilities. We will follow up with a release within a couple of weeks to address some of the remaining issues and fix items that our users discover. Yes, there will be bugs. Feel free to report them. But there are also lots of cool features, for which we owe a debt of gratitude to both the GStreamer and Twisted developers. Our website is at http://www.fluendo.com, the development site is up in wiki style at https://core.fluendo.com/trac/cgi-bin/trac.cgi Feel free to start filing issues. The actual tarball is up at: http://www.fluendo.com/downloads/flumotion-0.1.0.tar.bz2 Download the tarball and md5 file here. If you are running Fedora 2 you can get a full set of RPMS and needed dependencies from the GStreamer apt repository. I'm sure packages for other distributions will spring up over the next few days. Happy hacking and drop us a line ! Thomas

[Twisted-Python] why tests are failing with the gtk2 reactor + oldtrial but passing with newtrial
by Jonathan Simms 19 Oct '04

19 Oct '04

in a nutshell, oldtrial leaves the reactor in a dirty state in the gtk2 reactor i put in the follwing method: def printoutallreaders(self): for reader in reads.keys(): print "reader: %r" % reader in twisted.test.test_internet.InterfaceTestCase.testCallInNextIteration i added the following line (278): 277 reactor.callLater(0, f1) 278 reactor.printoutallreaders() upon running the test along with the whole suite i got the following output from my method: testCallInNextIteration ... reader: <twisted.internet.default._UnixWaker instance at 0x404d6b6c> reader: <Echo #0 on ./hello.skt> reader: <twisted.internet.tcp.Client to ('localhost', 50048) at 421a832c> reader: <Echo #0 on echo.skt> reader: <twisted.internet.tcp.Client to ('localhost', 50042) at 421d3b8c> reader: <Echo #0 on 0> reader: <twisted.internet.unix.Client instance at 0x4217836c> reader: <twisted.internet.protocol.ServerFactory on 50046> reader: <twisted.internet.unix.Client instance at 0x421784ac> reader: <Echo #0 on 0> reader: <Echo #0 on 0> reader: <twisted.internet.protocol.Factory on 50051> reader: <Echo #0 on echo.skt> reader: <twisted.protocols.ftp.DTPFactory on 50055> reader: <twisted.internet.protocol.ServerFactory on 50048> reader: <twisted.internet.tcp.Client to ('localhost', 50046) at 421bcaec> reader: <twisted.internet.unix.Client instance at 0x421d39ec> as you can see, old trial has left a large number of readables in the reactor between tests. when i run with the same code patched into the retrial-4 branch: testCallInNextIteration ... reader: <twisted.internet.default._UnixWaker instance at 0x4063c1ec> you can see that the only readable in the reactor is a _UnixWaker. so retrial caused this test to work by cleaning up the reactor state, as the test writer expected. In the end, it was a VERY GOOD THING that JP demanded that I revert the merge of my branch, as the reactor-installation code was flawed. JP WAS RIGHT I WAS WRONG let that be a lesson to you all... it is fixed now in my branch, ans i'm going to test it on pyramid before remerging to make sure there are no further buildbot suprises. -Jonathan

[Twisted-Python] twisted.internet and IPv6
by Stefan Behnel 18 Oct '04

18 Oct '04

Hi! I'm curious: how much work would it be to enable IPv6 support in twisted.internet? When I do --------------------------------------- cd twisted/internet fgrep INET *.py --------------------------------------- I get a number of references to IPv4 that make me believe that t.i.* is not quite IPv6 clean by itself: --------------------------------------- default.py: server = socket.socket(socket.AF_INET, socket.SOCK_STREAM) default.py: client = socket.socket(socket.AF_INET, socket.SOCK_STREAM) javareactor.py: return ('INET', InetAddress.getLocalHost().getHostAddress(), self.jport.port) javareactor.py: return ('INET', addr.getHostAddress(), self.skt.getPort()) javareactor.py: return ("INET", self.host, self.port) tcp.py: addressFamily = socket.AF_INET tcp.py: return address.IPv4Address('TCP', *(self.socket.getsockname() + ('INET',))) tcp.py: return address.IPv4Address('TCP', *(self.addr + ('INET',))) tcp.py: return address.IPv4Address('TCP', *(self.socket.getsockname() + ('INET',))) tcp.py: return address.IPv4Address('TCP', *(self.client + ('INET',))) tcp.py: addressFamily = socket.AF_INET tcp.py: return address.IPv4Address('TCP', *(self.socket.getsockname() + ('INET',))) tcp.py: return address.IPv4Address('TCP', self.host, self.port, 'INET') udp.py: addressFamily = socket.AF_INET udp.py: return address.IPv4Address('UDP', *(self.socket.getsockname() + ('INET_UDP',))) udp.py: Returns a tuple of ('INET_UDP', hostname, port), indicating udp.py: return address.IPv4Address('UDP', self.remotehost, self.remoteport, 'INET_UDP') --------------------------------------- What would be needed? Would a new reactor be a good solution? "reactor6" ? Or rather extending the current one? I'd say a reactor6 would be cleaner, but on the other hand, a simple flag could do the trick from the API perspective. Any comments on this? Stefan

hi; i was writing third party sip call controller when a friend suggested i use twisted. I think it will save me a lot of time, but i had trouble with the following when installing: cvs the pserial and pcrypto required package. the cvs server complians about a wrong password (any hints) i continued without these package and installed using setup.py. Where is a good place to start (the tutorial provided is not really very great) - any other suggestions? moe smadi

[Twisted-Python] UDP multicasting? HowTo?
by Artūras Šlajus 17 Oct '04

17 Oct '04

Hello, At first I want to say, that I'm pretty new to Twisted and these classes get me lost (functional programming veteran :-)). Anyway, I started OOP month ago, and I need to write UDP Multicast client/server. What it's for? I want to write Gtk clone of Vypress Chat - serverless chat application. Erm, in fact I want to rewrite it, because I started writing it in Perl :-) So... I looked up API for Multicast and this got my eye: http://twistedmatrix.com/documents/current/api/twisted.internet.udp.Multica… It's probably right thing. But as I never done this before, I need an example.. I think my code should start like this: #!/usr/bin/env python # -*- coding: utf-8 -*- from twisted.internet.udp import MulticastPort from twisted.internet import reactor class VyChat(DatagramProtocol): But what's next? Anyway, any help or examples appreciated.

Every build slave is failing at least one test. It looks like retrial might be ready with a bit more work, but it isn't yet. Jp
