[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] Twisted.web and adbapi example?
by Morrow, Paul June 22, 2003

June 22, 2003

I've been pouring through the docs and examples, but can't find an example of a .rpy that generates a page containing the results of a database query. How would such a thing be properly architected? Clearly the adbapi would be involved, but then how do I get the query results into the string returned by my resource? Or would I use a deferred instead? Would someone please share a little code snippet (or point me at one)illustrating how that would best be accomplished? Thanks.

[Twisted-Python] Getting Rid of Application in a Compatible Way
by Moshe Zadka June 16, 2003

June 16, 2003

I suggest to write ApplicationService classes which look like: class TCPListener(ApplicationService): def __init__(self, port, factory, backlog=5, interface='', *args, **kwargs): self.port = port self.factory = factory self.backlog = backlog self.interface = interface ApplicationService.__init__(self, *args, **kwargs) def __getstate__(self): d = self.__dict__.copy() d['_port'] = None return d def startService(self): … [View More]

[Twisted-Python] Woven and WML
by Tim Allen June 2, 2003

June 2, 2003

I recently got a new WAP-capable phone, and since you can do a lot of interesting things by pointing it at various URLs, I thought I'd try making a cute little website in Woven for my phone to browse. Unfortunately, it seems that this is impossible. The resulting markup from my simple Woven test page had all sorts of woven-stuff all through it - such as pattern attributes that hadn't been removed, and id attributes that were woven's internal IDs, rather than the IDs I tried to set. … [View More]

[Twisted-Python] pb.Copyable docs
by Jeff Hodges May 31, 2003

May 31, 2003

As a newb, I've found the howtos invaluable but I came across a problem when I attempted to write code based on pb.Copyable class. Some of the code holds vaguely described variables such as "state" and "perspective". I've inferred a little bit from other bits of documentation but can't seem to fit it all together. This line was most disconcerting to me: "XXX: understand, then explain use of varying cached state depending upon perspective." Anyone help a poor newbie out? Thanks, folks. -- Jeff

[Twisted-Python] Woven example for article, Part II

I don't mean to belabor the point, but my first try at the woven tutorial example produced a DeprecationWarning as part of its traceback. My first thought seeing that was that I probably needed an *earlier* version of Twisted, rather than a *later* one, to make the example work. As it turns out, … [View More]

Well, that sounds nice; but it's kinda impractical in a lot of contexts. As I mentioned in an upthread comment, my web host at python-hosting.com has 1.0.3 installed.

If you look at twisted.spread.pb you'll see that the pb.connect() function takes both a username (same as identity.name) and perspectiveName as parameters: def connect(host, port, username, password, serviceName, perspectiveName=None, client=None, timeout=None): """Connects and authenticates, then retrieves a PB service. Required arguments: - host -- the host the service is running on - port -- the port on the host to connect to - username -- the name you will be identified as to the authorizer - password -- the password for this username - serviceName -- name of the service to request Optional (keyword) arguments: - perspectiveName -- the name of the perspective to request, if different than the username - client -- XXX the \"reference\" argument to perspective.Perspective.attached - timeout -- see twisted.internet.tcp.Client @returns: A Deferred instance that gets a callback when the final Perspective is connected, and an errback when an error occurs at any stage of connecting. """ So my demo/hack client application supplies those details when a user logs on: def main(self): name = raw_input('Enter your login name (root): ') if not name: name = 'root' password = raw_input('Enter your password (password): ') if not password: password = 'password' perspective = raw_input('Enter your perspective (root:admin): ') if not perspective: perspective = 'root:admin' df = pb.connect(host='localhost', port=8789, username=name, password=password, serviceName='BankingService', perspectiveName=perspective, client=self, timeout=30) df.addCallbacks(self.gotPerspective, self.noPerspective) reactor.run() -- Patrick K.
