[Twisted-Python] deferToThread and thread pool
by Brian Granger Aug. 31, 2005

Aug. 31, 2005

I have a few questions about the default implementation of deferToThread. 1. Does deferToThread use a thread pool by default? If not, how can I enable this? 2. Which thread are the callbacks and errbacks of the deferred returned by deferToThread run in? Thanks in advance! Brian

[Twisted-Python] Nagle delays and twisted
by Brian Granger Aug. 30, 2005

Aug. 30, 2005

Hello all, I have been implementing a custom protocol with twisted and have been having some odd performance problems. My protocol consists of a TCP connection with multiple client/server commands. For some types of commands, I found it took about 200 ms for the client and server to complete. Because this was over loopback (which has a ping of 0.1 ms), it seems very slow. Because I am keeping the socket connected, I am not measuring the socket setup time. Lucky for me, there … [View More]

[Twisted-Python] gthreadless.py
by Stefano Masini Aug. 30, 2005

Aug. 30, 2005

Hello twisted folks, I reimplemented gthreadless.py, originally implemented by Chris Armstrong. My implementation aims to be more robust and is currently used in a large project, therefore it is already usable. http://www.pragma2000.com/wiki/index.php?GThreadless gthreadless is a twisted module that makes use of greenlets to implement the very nice primitive blockOn(d), that suspends the execution in the current stack frame while waiting for the deferred to fire. This way you can use a … [View More]

[Twisted-Python] Use python logging module with Twisted log
by Remi Cool Aug. 29, 2005

Aug. 29, 2005

G'day, I've created an xmlrpc server with twisted and was wondering if it would be possible to use twisted logging and the python logging module together. This because the xmlrpc server uses a 'back-end' that contains python modules that are also used by other processes/servers. It should be possible if a twisted handler for the python logging module existed ... it would then be a case of attaching the twisted handler to the logger and the connection would be established. Before I take on … [View More]

Sorry, I can't help you, but I'd need the same (plus logging to some wx window), and I've no time to investigate and write it myself - so would you please release it, if you implement such? I'd be very glad! Best regards, Henning Hraban Ramm Südkurier Medienhaus / MediaPro Support/Admin/Development Dept.

[Twisted-Python] twisted 1.3.0 unit test errors
by Warren Pollans Aug. 29, 2005

Aug. 29, 2005

Hello, I've started installing selenium on my ibook (OSX.3.9, python 2.3) I just installed Twisted 1.3.0. When I run admin/runtests from the install directory, I get the following results - Are these failures and errors acceptable? I've installed pyOpenSSL and pyCrypto, but not pySerial FAILED (failures=4, errors=2, skips=33, expectedFailures=4) Are these acceptable? Or what do I need to do to try to fix this before continuing the selenium install?

[Twisted-Python] Interfaces and adapters
by en.karpachov＠ospaz.ru Aug. 28, 2005

Aug. 28, 2005

Let's say we defined an interface and an adapter: class IFoo(zope.interfaces.Interface): pass twisted.python.components.registerAdapter(Foo, Bar, IFoo) As it is for now, the registerAdapter accepts any Foo, without regarding what it implements. Could somebody give any rationale why this condition shouldn't always hold: foo = IFoo(bar) assert IFoo.providedBy(foo) Seems it is not unreasonable to expect this behaviour, because it is exactly what interfaces are all about, or am I wrong? -- jk
