[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] [patch] mktap web --resource
by Sune Kirkeby Aug. 12, 2002

Aug. 12, 2002

Hi, all! Attached is a short patch to add a --resource option to "mktap web", here is the --help for it: -r, --resource= <class> is the name (including module) of a subclass of twisted.web.resource.Resource to publish. So you can have any subclass of t.w.r.Resource be the 'root' of your web-server. I have also been working on a few other things: - an async Pytho-only PostgreSQL interface (not t.e.adbapi compatible, since I am not usre I like it's interface … [View More]

[Twisted-Python] Patch for dbauth.tac in examples
by Steve Waterbury Aug. 6, 2002

Aug. 6, 2002

Since I want to implement a PB-based app with db authorization, I was tinkering with the dbauth.tac example in an effort to educate myself. Changed "passport" to "cred" and set the database explicitly (created the dbcred tables in the "twisted" database that bugs uses). "Create an Identity", "remove", and "[change] password" work; there seems to be a problem with gotPerspectives' call to dbgadgets.py, but I haven't messed with gadgets (don't need them yet), so I won't be looking at … [View More]

[Twisted-Python] Dynamic web application using twisted.web.resource
by Mukhsein Johari Aug. 3, 2002

Aug. 3, 2002

Hello fellow twisters, This is a question (albeit a long one) directed at twisted.web and resource. The project: I would like to serve a dynamic website using the twisted web server. I understand that the webserver's 'root' directory can be set at a file? I may have a misunderstanding of the code and docs but if so, feel free to set me straight. The website (not real): http://www.mywebsite.com/ This is the root of the site, which is in reality a erm..rpy? program? Which means that there … [View More]

[Twisted-Python] You guys rock
by barry＠zope.com July 31, 2002

July 31, 2002

I wanted to test out some news/mail gatewaying for Mailman 2.1 but I didn't want to go through the hassle of actually connecting things up to a real news server, and I /definitely/ didn't want to actually try to install inn or some nonesense (I'd like to do some other work this week :). I wished I had something like Lib/smtpd.py in the Python distro for the server side of NNTP, then it dawned on me that I remember Moshe and crew saying that Twisted comes with a news server. Well, let's just … [View More]

[Twisted-Python] Please allow download of tarballs from viewcvs[2]

July 30, 2002

[Sorry, forgot to sign the mail] Hello, list, would you mind to allow the generation of tarballs from cvs repository on the fly? It is technically possible in viewcvs, at least on new versions. It is a Setting in viewcvs's configuration file. I can't use cvs in itself because of firewall issues on customer's site. Cvsgrab doesn't cut it either, because it can't handle the parameter handling of your viewcvs installation. Another possibility would be an upgrade to viewcvs à la sourceforge, … [View More]

[Twisted-Python] API docs
by Christopher Armstrong July 30, 2002

July 30, 2002

I was talking to MetaCosm, and he said the template for API docs he uses in his professional projects is like so: """ Usage: foo() -> baz Examples: if blah(): foo() Big Picture: (!!) This class is meant to be used in a Quuxer, and you should usually override the getBaz method to return a Spam instance, although it's not required. NOTES: This class is currently in a state of flux; it will soon be refactored, so watch out for API changes """ etc. The main thing here is "Big … [View More]

[Twisted-Python] FAST 03 (Usenix conference on File Storage Technologies)

I was looking for interesting conferences where Strakt could present a paper and found this one. I think that a paper on Twisted would be accepted if anybody is interested in writing one. 4000 - 6000 words due Sept 03. (Automatic extension to Sept 10). There is also a request for 'works in progress' and 'provocative opinions'. These only have to be one page long. They mention that they are particularly interested in student work.

[Twisted-Python] Two things in twisted.internet.process
by Matt Campbell July 29, 2002

July 29, 2002

1. I noticed that when Process.__init__ prepares to execute the child process, it closes all fd's from 3 to 255. Is it possible for the child process to inherit open files with fd's greater than 255? I'm concerned that this could happen on busy servers, but this is one aspect of Unix about which I don't know much. 2. To increase consistency with the usual interface between transports and protocols, I think it would be good to implement a loseConnection method in the Process class that does … [View More]

[Twisted-Python] suckosity of text/html as default content type
by Jaakko Niemi July 28, 2002

July 28, 2002

Ok, serving files with content-type set to text/html just blows. Basic logic is that the server should know and set content-type header or set it to application/octet-stream if unknown. A http client can then decide what to do with it. Attached patchlet is in existence just because I don't like opening my mouth without something concrete. Files without extension in their names for example are still not handled properly. I'm going to add parser for mime-types file unless radix beats me to it. --j

[Twisted-Python] New client APIs
by Itamar Shtull-Trauring July 28, 2002

July 28, 2002

Hi, I just checked in a new API for client connections (TCP/SSL/UNIX.) The main change is that you now register a ClientFactory using reactor.connectTCP (or Application.connectTCP). Various callbacks will get called on the factory, allowing you to reconnect on a failure or lost connection, let users abort connections, and so on. So, these policies are now done in the *factory* - connectionFailed will no longer be called on protocols unless you use the old deprecated APIs. So what does … [View More]

[Twisted-Python] Newbie: Help with twisted.web, HTTPClient
by Daniel Burr July 28, 2002

July 28, 2002

I just started playing with Twisted last week; great stuff! My question is this: I have an .rpy file, which defines a Resource. As part of this Resource's render method, I need to perform an http GET against another server, which of course causes the twisted.web server to block. From looking through the source code, it looks like the HTTPClient should be what I need to perform a non-blocking http GET from within my resource, but I cannot find any information on how to use it; just creating … [View More]

[Twisted-Python] Have you checked out CherryPy?
by Mukhsein Johari July 26, 2002

July 26, 2002

Hello all, There's an interesting light-weight web application platform called CherryPy (why cherry? who knows..). The idea of generating the web server from source is similar to twisted's mktap. However, it takes .cpy files and creates a .py which is run like a normal python program: $ python MyWebApp.py This will launch a web server listening on port 8000 by default. CherryPy has 2 templating laguages which serve different purposes. It's actually quite simple to use as far as … [View More]

Yes, I have heard of Services, but there is apparently no doc, and I am ignoring the concept of services until I am forced to deal with it. I think a "Writing your application with Twisted" doc would be perfect. Regards, Zooko

> The normal idiom here is to have your "userapp" inherit from protocol.Factory. > The default "factory" implementation does set itself as an attribute on the > protocols it builds... Ah! Of course. Thanks. I tend to prefer other techniques (like AFactory) over inheritance when possible, but since inheritance is the Twisted Way, I'll do it that way. Maybe this idiom should be added to plugin.html? Regards, Zooko

[Twisted-Python] AFactory
by Zooko July 25, 2002

July 25, 2002

Folks: In writing my Gnutella for Twisted implementation, which I have named "Zoot", I encountered what seems to be a bit of a weakness in the current "Factory" API. This occurred when I wanted each protocol instance to have a reference to my Zoot object (the Zoot object contains the Gnutella logic for such operations as routing a message from one connection to another). The way to do this is to make a subclass of Factory, which I called ZootFactory. ZootFactory gets a reference to the … [View More]

[Twisted-Python] [PATCH] domhelpers.py

July 24, 2002

I've been working on porting the blog example to the new 0.19 DOMTemplate format, as an opportunity to play with some Twisted code. In doing so, I think I've found this big, bad single-line, 5 character patch for domhelpers.py. Patch is attached. AFAICT, this is correct; I'll admit, though, I'm a python journeyman at best, so I may have mis-fixed. Also, I should be finished with the blog example in a day or two...is there interest in replacing the old-style one? If so, where should I send the … [View More]

[Twisted-Python] Reality?
by Josiah Carlson July 24, 2002

July 24, 2002

Good day, I was just mucking around in the #python channel talking with some guys, and ended up expressing my opinion of Reality, which at this point is not very high. Why you ask? I suppose my biggest problem is documentation and the lack of a proper distribution. In order to get reality, I had to use CVS, not a big deal, but I would have been much more contented with a tgz archive. You know, it could include that 'demo' world I've read about after searching through the mailing list … [View More]archives. Along those same lines, nowhere in the cvs listing is _ANY_ documentation, save the docstrings in the source. Not to mention that on the twistedmatrix.com site, there is only passing reference to reality and how to get to it (get it from cvs, but you need to use the command: cvs -d:pserver:anon@twistedmatrix.com:/cvs co Reality Which I don't believe is listed anywhere on the twistedmatrix.com site. Along the 'demo' world I referred to above, information about that is also not listed on the twistedmatrix.com site, anywhere in the source (that I could find), documentation is nowhere to be found, save in the email archives...but email lists are not documentation. To get to the point; if you want people to use reality, get a distribution of any stable version, a world file with help about what is currently available in the mini-world, and a little how-to for getting the thing to run. It also wouldn't hurt to get a link to this distribution on some download page at twisted. I'm telling you this because I have just embarked on a project that quite possibly could last until I start my phd in september - possibly longer. Building a mud server and a mud using the server. I'm doing this because I don't believe any mud servers currently available are workable solutions to the problem of 'how do I make my mud do X', where X is anything. I want to make a DND 3rd ed rule-based mud. CircleMUD, SMAUG, ROM, ENVY, etc., are all 2nd ed based. Pulling out all that code for thaco, percent-based skills/spells, etc., and replacing it with D20 rules would be a daunting task (there are 3 guys who did it this past spring with CircleMud for a class, but their source is not downloadable). I'm not looking to re-make something that is doing too-much already. At 37k lines of code for circlemud, and nearly 140k lines for SMAUG, either is too huge. Reality is a nice change, but it still feels bulky (in terms of source code size) and I wouldn't want to muck around in the source for anything. Thanks, - Josiah Carlson [View Less]

[Twisted-Python] Python 1.5
by Christopher Armstrong July 23, 2002

What's the deal with 1.5.2 compatibility? For a while, it was understood (at least in the IRC clique) that we would be getting rid of it as soon as Woody came out. Is this still true? Personally, I think it's high time we switch to 2.1. Who wants to stay with 1.5.2?
