[Twisted-Python] Coil command-line app
by Itamar Shtull-Trauring 27 Mar '02

27 Mar '02

Hi all, I will soon be writing a coil command line app. It will let you edit an exisiting .tap. Ports it creates will not be activated, and its own webserver won't show up in the config interface since it will be configuring a different Application insatnce. This will very likely replace "mktap coil" for most uses. It'll working something like this: $ coil exisiting.tap (config an existing tap) $ coil -n "email-server" email.tap (create a new application instance and store it in tap) Any suggestions for possible functionality?

[Twisted-Python] Anonymous CVS pserver access
by Christopher Armstrong 25 Mar '02

25 Mar '02

Today I added an "anon" user to the pserver running on zaibach, allowing anonymous users to check out the CVS Twisted code. The commands: cvs -d:pserver:anon@twistedmatrix.com:/cvs login You can just hit <enter> when you get the password prompt, then: cvs -d:pserver:anon@twistedmatrix.com:/cvs co Twisted You should then have the Twisted code in the "Twisted" subdirectory. I added a "CVS Access" page to the website at http://twistedmatrix.com/developer/cvs, if anyone wants to write up a paragraph on accessing the repository through windows, it'd be appreciated; if not, I'll add it the next time I get around to twiddling with wincvs. -- Chris Armstrong << radix(a)twistedmatrix.com >> http://twistedmatrix.com/users/carmstro.twistd/

[Twisted-Python] Aaargh

""" The Win32 event mechanism (e.g. WaitForMultipleObjects()) can only wait on 64 event objects at a time. """ Same as select(). so we may need to use multiple threads for the win32 event loop.

[Twisted-Python] win32 process problem
by Drew Whitehouse 20 Mar '02

20 Mar '02

Hi Itamar, I'm just getting into twisted, after our IRC chat the other day. Looks like it does everything I need (plus a lot more !). I'm having some trouble with Process and win32, i.e. I'm already using bleeding edge CVS versions ... I'm trying to run a http server which services XMLRPC calls. The XMLRPC calls then have to launch a process that the server needs to keep track of, getting notified when the process exits. Anyhow it seems the new win32 process stuff is giving trouble. It only allows one XMLRPC call before the server hangs. I'm testing with the following code. I realize that this code is brand new, but thought I'd send it along in case you hadn't seen the problem already. -Drew -----------server.py------------------ import sys,os if sys.platform == 'win32': from twisted.internet import win32 print 'Installing WIN32 version of process handling etc ...' win32.install() from twisted.web import xmlrpc from twisted.python import defer import xmlrpclib class Echoer(xmlrpc.XMLRPC): def _getFunction(self, functionPath): """Convert the functionPath to a method beginning with 'xmlrpc_'. For example, 'echo' returns the method 'xmlrpc_echo'. """ f = getattr(self, "xmlrpc_%s" % functionPath, None) if f: return f else: raise xmlrpc.NoSuchFunction def xmlrpc_hello(self): """Return 'hello, world'.""" return 'hello, world!' def main(): from twisted.internet.app import Application from twisted.web import server app = Application("xmlrpc") r = Echoer() app.listenTCP(7080, server.Site(r)) app.run(0) if __name__ == '__main__': main() and -------client.py------------------------ import xmlrpclib proxy = xmlrpclib.Server("http://localhost:7080/") r = proxy.hello() print r -Drew ;; Drew.Whitehouse(a)anu.edu.au Sci-Viz/VR Programmer ;; http://anusf.anu.edu.au/~drw900 ANUSF VIZLAB ;; Australian National University Supercomputer Facility

[Twisted-Python] New scripts
by j.her＠t-online.de 20 Mar '02

20 Mar '02

Hi! mktap is now fully moved to twisted.scripts. Would be nice if people moved the commands they use the most, or are related to the part they developed. What to do: 1. Copy the code of the command to twisted/scripts/command.py. Then first commit it unchanged, so there is a clear history! 1. Move as much code as possible into a function named run(); try to avoid top-level code if you can, since that is a problem for doc-tools, pychecker, etc. 2. Replace the command in bin/command by its stub, i.e. by the new preamble + the import/run() combo. Don't skip this step, since otherwise ppl will start to edit at two places, which leads to chaos! See bin/mktap and twisted/scripts/mktap.py for an example. In the long run, especially when all commands are moved, be can remove the bin directory, since it's created in build/scripts anyway. For now, it allows smooth transition. Ciao, Jürgen

[Twisted-Python] cvs script failure
by j.her＠t-online.de 19 Mar '02

Hi! On a second look, this seems to be caused by CVS using my local settings. Still, shouldn't the CVS scripts take care to use a special, well-known system path to "their" Twisted? Ciao, Jürgen

[Twisted-Python] Some Win32 comments
by Tyler W. Wilson 19 Mar '02

19 Mar '02

I was trying to get the Twisted IM client running, and have a few comments related to config issues on Win32. Here they are: 1 running 'python setup.py install' copies the twisted folder to the <python>\lib\site-packages folder, which is okay. but if you change to the Twisted<version> folder and do 'python bin\im', it will be using the sources from the original location, NOT the site-packages location. 2 similar to the above, if you set PYTHONPATH to point to Twisted<version> folder, as it says to do in the README, the original twisted files will be used, not those copied to the site-packages folder. so, given 1 & 2, do we really need to do the setup.py? It should be noted in the README(.win32?) that users should either: 1) set PYTHONPATH to Twisted<version> and NOT run setup.py, and include the full path to im, mktap, etc, or 2) do NOT set PYTHONPATH, run setup.py, and still include the fullpath to the bin folder. i would also suggest that the files in the bin folder have the .py extension, so that on Windows we can associate them to the python interpreter, which would simplify things. 3 im (Tk) fails to save config state, if HOME is not set, since the ~ will return exactly, and this is an invalid filename charcter under Win9x. Either split it to check, or put in an error/warning. here is a fix i made to mine, which should work on all platforms: tkim.py, line 912: path = ".imsaved" home = os.path.expanduser("~") if home != "~": path = home+os.sep+path Thanks, Tyler

[Twisted-Python] We now have a bug tracker
by Itamar Shtull-Trauring 19 Mar '02

19 Mar '02

http://twistedmatrix.com/users/itamarst.twistd/bugs/ It's using twisted.bugs, which is of course still a work in progress, but it's good enough to add bugs to. Please submit all and any bugs, feature wishes and so on.
