Thanks, I'll check back later then. For future reference, if I could have gotten twisted.mail working, I was interested in using it on a low traffic Mailman host.

[Twisted-Python] PyCon Devel Sprint
by Christopher Armstrong Jan. 17, 2003

Jan. 17, 2003

Who wants to participate in the development sprint before PyCon? (The 24th and 25th of March.) It will require a fee, which will be less than $50, estimated. I'll put together the sprint proposal and submit it once I know how many people we can expect. Reply here or mention it to me on IRC and I'll add your name to the list (along with a vote for what we should hack on in particular, if you've got one). -- Twisted | Christopher Armstrong: International Man of Twistery Radix | … [View More]

[Twisted-Python] DOMTemplate best practice
by Mario Ruggier Jan. 17, 2003

Jan. 17, 2003

Hello, I am playing with the examples and howtos, to try and figure some of this thing out. The DOMTemplate HowTo goes through a simple example, and uses 3 files, one for the template itself, one for a resource that sits next to the template file, and one for the code that actually instantiates the template (and this one must be put in the pythonpath). My question is that, given that this 3rd file (webquoteresource.py in this example) is anyhow dedicated to this template (and will always … [View More]

[Twisted-Python] A nit on "Generalization of Deferred Execution in Python"
by Tommi Virtanen Jan. 17, 2003

Jan. 17, 2003

http://cumulo-nimbus.mit.edu/deferex.xhtml "It is suggested that methods which must perform long-running calculations or communication with a remote host may return a Deferred." That's a horribly misleading paragraph. What you probably want to say is that you recommend such things to return a Deferred -- I currently read that such that functions should sometimes return Deferreds and sometimes real results, and that is very confusing. That's why there are defer.succeed() and defer.fail().

Yes, I've looked at journal. I don't fully understand your implementation, because I don't fully understand Twisted yet. And, I had already started PyPerSyst before I knew about your implementation. Now I can't let it go. I'm sure you know how that is. :-) > > We recently added support for Pyro, which gives you client/server > > RMI-like remote access.

This is insecure, > and even if that is acceptable limits you to Python clients only. I'm not too worried about the limitation to Python clients. The security issue is a different matter. It looks like Pyro now supports XML pickles: <quote> Whether the marshaling is done using the safe xml pickling (from Gnosis_utils or PyXML) or the default pickle. The xml_pickle is not vulnerable for the pickle trojan problem mentioned in Chapter 7, but it is an order of a magnitude slower, and requires more bandwith. Use "any" for any implementation (defaults to PyXML), "pyxml" for PyXML, "gnosis" for Gnosis. PyXML seems to be about three times faster than Gnosis. You need to have installed Gnosis_Utils (at least version 1.0.2, latest is 1.0.5 at the time of writing). For PyXML, you need at least version 0.8, latest is 0.8.1 at the time of writing. </quote> > Twisted's remote object protocol Perspective Broker on the other hand > does not use pickles, and can in fact be used with other languages (a > Java implementation exists), while still offering many of the features > Pyro provides. PyPerSyst works with Pyro, but doesn't depend on it. I'd like to accomplish the same with Twisted. I started with Pyro because it was easier for me to figure out. Any suggestions for getting up-to-speed on Perspective Broker? Anything else I need to be aware of for this kind of application? -- Patrick K.

[Twisted-Python] twisted.mail startup
by larryt＠winfirst.com Jan. 17, 2003

Jan. 17, 2003

Is there a set of options that I can feed mktap mail that will start up twistedmail as a sendmail replacement on my linux box. I guess I'm looking for something like the howto using-twistedweb.html, except of course for twistedmail. thanks, larry

[Twisted-Python] Debian Package Breakage
by Moshe Zadka Jan. 17, 2003

Jan. 17, 2003

Dear Twisted Developers, Concern has been expressed why the Debian build process is so easy to break. I will try to address this concern here, but first let me reiterate my request: please, let me or the list know *in advance* of any change which might break the package build. If there is any doubt, an e-mail to the t-p list is better than breakage. Because the Debian package build is a part of the release procedure, breaking it means achieving a non-releasable state, something I'm sure none … [View More]

[Twisted-Python] PyPI evangelism :)
by Anthony Baxter Jan. 17, 2003

Jan. 17, 2003

If you're running Python 2.3a1 or Python CVS, your distutils supports the python package index, (PEP 301). This is just evangelism to try to get people to register their packages - ooo, like, fr instance, twisted :) http://www.amk.ca/cgi-bin/pypi.cgi is the current test version of the interface. Adding more packages makes it more useful <hinthint>

[Twisted-Python] Cocoa (OS X) twisted example
by Bob Ippolito Jan. 17, 2003

Jan. 17, 2003

http://redivi.com/~bob/twisted-cocoaDemo.tgz Essentially just a port of the QT "Twistzilla" example using the pyobjc project template and polling the default reactor with a NSTimer. Requires pyobjc (the released version is ok, no need for CVS). Python must also be able to find pyobjc and twisted (i.e. in site-packages or dropped into the app bundle). If you were to compile it and drop twisted+pyobjc in the bundle, it would run on any box with OS X 10.2+. See http://pyobjc.sourceforge.… [View More]

[Twisted-Python] twisted web on MacOSX -- apache, 80, firewall
by Mario Ruggier Jan. 17, 2003

Jan. 17, 2003

I'm trying to install, and understand, twisted (1.0.2alpha1) web server on a MacOS X 10.2.3 powerbook (a platform i am at the same time learning about). Installation of twisted seems OK (even if with a number of exceptions from admin/runtests, for which I temporarily put the log under twistd web, at: http://ruggier.dyndns.org:8080/test.log ). Getting the web server up to serve flat files was also successful. However, macos x comes with apache on port 80 (turned on via Sharing->Services-… [View More]
