[Twisted-Python] correction to patch to tap.ftp
by Amir Bakhtiar Feb. 26, 2003

Feb. 26, 2003

Got confused by the interplay of optParameters and opt_ methods. Here is a simplified version of my earlier patch. This patch allows username and password pairs to be defined. e.g. mktap ftp -uamir -wfoo mktap ftp -uamir:glyph -wfoo:bar -A- --- ftp.py 2003-02-26 12:41:27.000000000 -0800 +++ ftp.orig.py 2003-02-26 11:31:15.000000000 -0800 @@ -33,16 +33,14 @@ optParameters = [ ["port", "p", "2121", "set the port number"], ["root", "r", "/usr/local/ftp", "define the root of the ftp-site."], - ["useranonymous", "", "anonymous", "Name of the anonymous user."], - ["username", "u", "twisted","set login username. colon separate for multiple."], - ["password", "w", "twisted","set password. colon separate for multiple."] + ["useranonymous", "", "anonymous", "Name of the anonymous user."] ] optFlags = [["anonymous", "a","allow anonymous logins"], ["thirdparty", "3", "allow third-party connections"], ["otp", "","activate One-Time Passwords"]] longdesc = '' - + def addUser(factory, username, password): factory.userdict[username] = {} @@ -62,15 +60,8 @@ t.otp = config.opts['otp'] t.userdict = {} - if config.opts['username']: - # Adding specified users - unames = config.opts['username'].split(':') - pwords = config.opts['password'].split(':') - for u, p in zip(unames, pwords): - addUser(t, u, p) - else: - # Adding a default user - addUser(t, "twisted", "twisted") + # adding a default user + addUser(t, "twisted", "twisted") try: portno = int(config.opts['port'])

[Twisted-Python] how to get those pretty tracebacks
by Clark C. Evans Feb. 26, 2003

Feb. 26, 2003

I'm currently using the "delayed" processing, and I was wondering how I could get the pretty "web.Server" traceback when an error happens... right now I got an ugly thing I wrote... ;)

[Twisted-Python] problems w/ pyPgSQL and the Enterprise HOWTO
by Justin Ryan Feb. 26, 2003

Feb. 26, 2003

Hiya all, I'm playing around with the basics of Twisted.Enterprise, and am having some trouble. I seem to have fixed it, but am unsure why the example in the howto ( http://twistedmatrix.com/documents/howto/enterprise ) did not work off the bat. I'm using pyPgSQL to connect to postgres. Here goes: The howto suggests: <- snip -> class AgeDatabase(adbapi.Augmentation): def getAge(self, name): sql = """SELECT Age FROM People WHERE name = ?""" return self.runQuery(sql, name) <- snip -> Unfortunately, I get a TypeError which is only fixed by changing this to: <- snip -> class AgeDatabase(adbapi.Augmentation): def getAge(self, name): sql = """ SELECT "Age" FROM "People" WHERE "Name" = '%s'""" \ % name return self.runQuery(sql) <- snip -> FWIW, postgres requires you to enclose mixed-case relations in double-quotes (else it pretends they are all lowercase). I did have to make all of the modifications in this second version to the original query (whilst still including the ?, instead of %s) in order for the query to be valid. I don't think that this would change anything, but I suppose I could try it with all lowercase tables just for kicks.. Is this a problem with pyPgSQL? something else? pyPgSQL is the _recommended_ module in the enterprise howto, so I didn't expect to run into trouble with it.. Thanks in advance twisted.list! :) -Justin

[Twisted-Python] Beginning of jabber client protocol
by Neil Blakey-Milner Feb. 25, 2003

Feb. 25, 2003

Hi all, Attached is some playing around I've done with twisted and jabber as a client. Not pretty, but just wanted to explore how microdom could be used on the xml stream protocol jabber uses. It can: . connect . receive messages . send messages . understand subscription requests . understand rosters . set online That's about it, but I'm unlikely to have much time to spend on this for some time, so I'm looking for comments on how to do it better for when I do get time, and/or support for other functionality. One thing I do know could be done better is callbacks for queries and presence indicators. Cheers, Neil -- Neil Blakey-Milner nbm(a)mithrandr.moria.org

[Twisted-Python] MSN Support
by Sam Jordan Feb. 25, 2003

Feb. 25, 2003

Hi, I've implemented protocol support for MSNP7 (MSN Messenger) (client only) using Twisted and I thought I'd post to the list to see if there was general interest in getting this added to Twisted. The hope is that (eventually ;)) twisted.im will have msn support, this being the first step. The module is at http://www.twistedmatrix.com/users/sam/msn/msn.py.txt API docs at http://www.twistedmatrix.com/users/sam/msn/docs/ and a small number of tests at http://www.twistedmatrix.com/users/sam/msn/test_msn.py.txt There's still plans for more stuff to be added, but it's in a useable state. If I get the go ahead i'd be happy to commit it. Any general feedback is appreciated. Cheers, Sam.

[Twisted-Python] SOCKS5 Client if anyone cares
by Dmitry Litovchenko Feb. 25, 2003

Feb. 25, 2003

Hello twisted-python, Sorry no unit tests at this time, I have prepared SOCKS5 unit test at the very beginning but there were added several parameters so Protocol constructors don't start correctly. I will fix this eventually. To code guardians: Please review this somehow, all notices about violations of Twisted standards are welcome. Unit is proven to work with anonymous connections, unit tests proven that authenticated connections are also ok. -- Best regards, Dmitry mailto:kwaker@uch.net

Hi, I did an other litle example to see how can work session. A shop where you put some articles in your bag... I do request.getSession() and set attribute directly to the session... Is it the good way ? import twisted.web.resource import cgi class Shop(twisted.web.resource.Resource): """ ReportRequest with forms and cookies """ articles=("chocolate","banana","apple") def isLeaf(self): return true def render(self, request): session = request.getSession() try: bag = session.bag except AttributeError: bag = session.bag={} try: article = request.args["put"][0] bag[article] = session.bag.get(article,0)+1 except KeyError: pass # no article to put out = [] out.append("""<html><body>What do you want to put in your bag ? <a href='?put=chocolate'>chocolate</a> <a href='?put=banana'>banana</a> <a href='?put=apple'>apple</a> """) if len(bag) == 0: out.append("Your bag is empty") else: out.append("You have in your bag : ") for k,v in bag.items(): out.append("%d %s "%(v,k)) return "".join(out) from twisted.internet import reactor from twisted.web import static, server site = server.Site(Shop()) reactor.listenTCP(8080,site) reactor.run()
