[Twisted-Python] Twisted Python 0.7.0 Prerelease Testing
by Glyph Lefkowitz 05 Aug '21

05 Aug '21

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. ______ __ __ _____ _ _ | ____ | \_/ |_____] |_____| |_____| |_____ | | | | @ t w i s t e d m a t r i x . c o m http://www.twistedmatrix.com/~glyph/

[Twisted-Python] [patch] mktap web --resource
by Sune Kirkeby 12 Aug '02

12 Aug '02

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 and need to play a bit before I figure out how I would like an async SQL-database interface to behave.) - a SQLResultWidget, very dull right now but I will probably hack some BoboDTML support into it. first-post-but-not-like-/.-ly yrs, -- Sune Kirkeby | /* we're still looking for the end of the | * server's header ... (does that make header | * parsing an "out of body experience" ? */ | -- jcc.c in junkex source-code

[Twisted-Python] We now have a coil command-line app in CVS
by Itamar Shtull-Trauring 02 Apr '02

02 Apr '02

Now you can configure your TAP files through the web! Usage: coil [--new=<application name>] <tap file> Options: -n, --new= -p, --port= [default: 9080] For example, to configure a TAP generated by mktap: $ mktap web $ coil web.tap (now point browser at http://localhost:9080) Or to create a new TAP: $ coil --new=myapp new.tap (now point browser at http://localhost:9080)

[Twisted-Python] More coil TODOs
by Itamar Shtull-Trauring 01 Apr '02

01 Apr '02

== Make ports visible == Currently, tcp/udp/ssl are treated as collections of protocol factories. I am going to change this to collections of Ports, so that you can configure interfaces to listen on, context factories for SSL, etc. The protocol factory will just be another attribute. This should have no effect on people who are coiling their apps. == Make old TAPs work == The refactor broke old taps - they can no longer be loaded since they refer to non-existence classes in twisted.internet.app. This can probably be easily solved (make a dummy PortsCollection class and delete the attributes of the loaded application that refer to it.)

Hi, My name is Joan Torres, I'm working in Port of Barcelona (spain), and I'm interested in learning more about how to use Twisted. I've two Python applications running on a Unix platform, both applications return a file as a result, and I want to write a server for them. The server should do the following things: - Execute Application1 every 10 minutes - Run Aplication1 on demand. - Keep the last file returned by application 1 - Execute Aplication2 on demand. There would be three different types of clients (windows platform): * Client type 1: get the latest file returned by applition1 * Client type 2: run application1 and get the returned file * Client type 3: run application2 and get the returned file The estimated amount of connections at a time could be: -clients type 1: 100 -clients type 2: 2-3 -clients type 3: 2-3 Could anyone give me some light on it?

[Twisted-Python] CVS broken?
by Itamar Shtull-Trauring 31 Mar '02

31 Mar '02

Each time I checkin a file, the CVS process then gets stuck (if I check-in two files it gets stuck after the first). I'm not sure why -- perhaps this is relevant (as pointed out by Tv): http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=102292 Or perhaps it's some other issue.

[Twisted-Python] Twisted bug -- bad interaction with popen
by Itamar Shtull-Trauring 31 Mar '02

31 Mar '02

This bug needs an answer from someone with unix expertise: <http://www.twistedmatrix.com/users/itamarst.twistd/bugs/view_bug?bug_id=8> I suggest getting rid of SIGCHLD handler, and having t.i.process.Process instances keep track of the pid of their process, and pass it to reapProcess so it only waitpid()s on a specific pid, and not all of them. I will add a test case which will test for this bug.

[Twisted-Python] Coil refactor more or less done
by Itamar Shtull-Trauring 30 Mar '02

Hi, Background: COIL is a configuration system for Twisted, allowing you to manage and configure your server via the web, developed by glyph. To test it out: $ mktap coil $ twistd -n -f coil.tap And point your browser at http://localhost:9080 In CVS, the coil system has been refactored, and now resides in twisted.coil. I feel that at this point it is now usable for configuring real apps. Real world use will help us find missing requirements and find issues and bugs. Examples of how to use it can be found in twisted.coil.plugins. Things that should really be coiled include cred, to the point that you can use coil to administrate users for manhole. t.mail is another candidate, and of course any servers based on twisted. If you are not using CVS Twisted, do not use coil - the interfaces have all been changed. You can still play around with it however, since it does work in the released code as well.

[Twisted-Python] MSN client code preview
by Ivo van der Wijk 30 Mar '02

30 Mar '02

Hi all, I did some heavy refactoring on my python MSN code this weekend. If anyone is interested in taking a sneak preview at the code (and comment on the API, etc), feel free to download some code at: http://ivo.freezope.org/pymsn200203250.tgz There's no docs (except for an msn protocol description), but there are two sample programs included: 'client.py' which is a very simple gtk/glade interface, and 'msntxttest.py' which basically echoes back anything that's sent to the client. The code is at this moment still very incomplete, and still needs loads of work, but you should be able to login using an existing msn handle/password, and send/receive messages. At this moment, I've only tested with everybuddy at the other end of the session - it may be that MS's msn client sends more noise that confuses the clients - I'll test this later. Patches, remarks, suggestions are welcome. Cheers, Ivo (VladDrac @ OPN) -- Drs.

[Twisted-Python] Re: [Twisted-commits] Better collection support for coil.

IMHO, the way this should work is: check the Configurator first. It is the authority on collection-hood, as it were. :-). If the *configurator* is not a collection, then check the configurable; this strikes me as a less likely case... in fact, it seems weird to introspect on the configurable at all at this point, since it isn't the configuration component. Does that make sense?
