[Twisted-Python] Signal Alternatives
by Moshe Zadka 07 May '03

07 May '03

Reference: http://moshez.org/curled.tgz So, I'm working on curled.killer, which may find its way back into Twisted at some point. The point is to have an API which resembles signals for command line users, and yet is flexible and reliable. On the server side, it should be no harder than killer.register(application, "signal-name", handlerFunction) On the client side, it should be no harder than % pbkill application.pbkill signal-name [optional arguments] Except for pbkill currently being spelled "python -c 'from curled.killer import killMain;killMain()', this is all working. Glyph mentioned he still has some comments, so I'm not checking this in yet, but I urge anyone who wants stuff classically triggered with signals on UNIX (such as termination, or configuration reloading) to try this out and submit feedback. PS This is UNIX only, as it uses UNIX domain sockets. It is too hard, and not interesting for me, to do it in Windows (maybe through TCP loopback sockets? ) -- Moshe Zadka -- http://moshez.org/ Buffy: I don't like you hanging out with someone that... short.

[Twisted-Python] stikiwiki promising, but...
by Richard Jones 06 May '03

06 May '03

I randomly found stikiwiki (in short: ReST/Twisted/WikiWiki) on the web, and thought it'd be extremely useful. Gave it a go, and had to immediately patch up some docutils usage quirks (docutils' API is a bit of a moving target ;). The results of my work are attached to this email. Can't find an email address for the author though, so that's as far as that patch goes :) Problem is that I now run into some problem deep in the Twisted code. The traceback is also attached. This is using the latest rc. If I should try the CVS, just let me know. Otherwise, is there something else that I could do? Richard ps. can't help thinking that Roundup would be nice running behind (or is it inside?) Twisted :) pps. stikiwiki: http://mithrandr.moria.org/code/stikiwiki/

[Twisted-Python] (no subject)

Hello, I'm new to twisted and have some questions: - Can I use a pb.Copyable as pb.RemoteReference? I have designed an wx-application and want request the wxframe from the server by the client. Events from the client should call methods of the server. Any idees? Thanks for help. best regards Martin Moellenbeck

[Twisted-Python] Missing files from installation of woven part
by Luc Stepniewski 06 May '03

06 May '03

When you do a python setup.py build/install, important files from t.web.woven are missing. The LivePage related files FlashConduit.fla, FlashConduit.swf, FlashConduitGlue.html, WebConduit2_mozilla.js, WebConduit2_msie.js and WebConduitGlue.html are not copied, so LivePage does not work at all without them :'-( Could anyone modify the installation to include these files in the copy? Thanks, Luc

[Twisted-Python] examples/echoserv_ssl.py, win32

Windows ME (yes, Windows ME, the trashy one) Python 2.2.2 Twisted 1.0.4 pyOpenSSL-0.4.1.win32-py2.2 (from sourceforge) OpenSSL 0.9.7b After fixing the reported bug in echoserv_ssl.py, I ran this at a cygwin prompt: $ python echoserv_ssl.py I tried running echoclient, and I get a dialog box saying: Python has caused an error in SSLEAY32.DLL. Python will now close. If you continue to experience problems, try restarting your computer. After clicking "OK" the echoclient_ssl quits. Alright... I won't do that. But I also get a stack trace in the server, which reproduces the error I get in my actual application. I don't really want an SSL client, I want an SSL server. So I point InternetExplorer to: https://127.0.0.1:8000. Same stack trace.

[Twisted-Python] fwd: Re: [Python-Dev] Distutils using apply
by Moshe Zadka 05 May '03

05 May '03

I suggest building modules with python2.3 -Wall -Wignore::PendingDeprecationWarning:distutils.command.build_py -Wignore::PendingDeprecationWarning:distutils.command.build_ext setup.py build (I'm very tame -- only ignoring PendingDeprecations of stuff that's been marked as non-fixable for Python 2.3). When 2.3 is officially released, we can add a line number (I don't want to do that before 2.3rc1 is out, so we won't have to constantly jiggle the number) Thanks, Moshe Forwarded message follows: To: Oren Tirosh <oren-py-d(a)hishome.net> From: Guido van Rossum <guido(a)python.org> Cc: Moshe Zadka <m(a)moshez.org>, python-dev(a)python.org Subject: Re: [Python-Dev] Distutils using apply > I was wondering if a milder form of deprecation may be appropriate for > some features such as the apply builtin: > > 1. Add a notice in docstring 'not recommended for new code' > 2. Move to 'obsolete' or 'backward compatibility' section in manual > 3. Do NOT produce a warning (pychecker may still do that) > 4. Do NOT plan removal of feature in a specific future release The form of deprecation used for apply() is already very mild (you don't get a warning unless you do -Wall). I don't think Moshe's use case is important enough to care; if Moshe cares, he can easily construct a command line argument or warnings.filterwarning() call to suppress the warnings he doesn't care about. --Guido van Rossum (home page: http://www.python.org/~guido/) -- Moshe Zadka -- http://moshez.org/ Buffy: I don't like you hanging out with someone that... short.

[Twisted-Python] Apply Deprecation
by Moshe Zadka 04 May '03

04 May '03

I've run a quick grep over the unittest log, and saw that an overwhelming majority of the errors come from relatively few places, namely: 104 twisted/test/test_internet.py:502 38 twisted/python/failure.py:230 31 twisted/enterprise/xmlreflector.py:94 24 twisted/spread/util.py:80 24 twisted/spread/util.py:76 These are five lines which, if properly fixed, would make the tests more readable. I realize there are good reasons for *not* stomping over the tree, randomly changing stuff, and I'm not suggesting it. I'm suggesting changing five lines.
