[Twisted-Python] Simple components question - IFoo(IBar(obj)) wont' work, what am I doing wrong?
by Michal Pasternak 21 Jun '04

21 Jun '04

Hi, I've hit a problem with compy, but it seems it's the same for Twisted Components. What am I doing wrong here? I bet I've overlooked something really simple, but I'm unable to find out. --------------------------------------------------------------------------- import twisted.python.components as compy class IFoo(compy.Interface): pass class IBar(compy.Interface): pass class x: pass class y(compy.Adapter): __implements__ = (IFoo,) pass class z(compy.Adapter): __implements__ = (IBar,) pass compy.registerAdapter(y, x, IFoo) compy.registerAdapter(z, y, IBar) IBar(IFoo(x())) --------------------------------------------------------------------------- ... this will fail with: twisted.python.components.CannotAdapt: <__main__.y instance at 0x80fc0ac> cannot be adapted to <class '__main__.IBar'>. -- m

[Twisted-Python] question about RSS + dynamic content...
by Stella Rockford 17 Jun '04

17 Jun '04

I am interestested in using Nevow as a templating alternative to ZPT. I am having difficulty triggering the nevow intepreter with very similar language as was included in the pycon 2004 PDF. If anyone could provide an example of rendering an RSS feed into a slot that is defined in an html tmeplate it would be very helpful indeed.

Re: [Twisted-Python] deprecated twisted.enterprise.dbcred (now removed?) has no newcred replacement

There are a couple of implementations newcred with enterprise in the tracker already. I need to get one ready for inclusion. I wonder, though, if it would be better to just have an example of implementing newcred with enterprise? dave ---- Original Message ---- From: Glyph Lefkowitz Date: Wed 6/16/04 11:06 To: twisted-python(a)twistedmatrix.com Subject: [Twisted-Python] deprecated twisted.enterprise.dbcred (now removed?) has no newcred replacement I think this constitutes a regression and I belive I will file a bug. Who should I assign it to?

[Twisted-Python] Refactoring of trial - call for feature requests and suggestions
by slyphon＠twistedmatrix.com 16 Jun '04

16 Jun '04

I am undertaking the refactoring of trial and i'm looking for suggestions as to what features people think trial lacks, what they'd like it to do that it never did, and so on. So far, I have received the following improvements/feature requests on #twisted: - Support test methods returning deferreds rather than needing to explicitly block for results - Better reactor cleaning - A component-oriented approach to allow for easier extension and customization of the test running/reporting process - Improved error reporting (allow for the reporter to report more than a one traceback) - (possibly) Add additional function attribute tags to allow for more expressive explanation of test failures. I had two suggestions, a "broken" attribute would be used to indicate that a failure did not indicate an error in the code being tested, the other would be a "known_issue" that would indicate a test failure is not a regression, rather is a new test that tests for a known issue, and therefore it should be noted and fixed, but isn't a show-stopper (so to speak) I'd be interested to hear your suggestions and comments and such. -Jonathan

I want to put an apache server in from of the twisted server. Whenever apache receives a request, it dispatches it to the twisted. twisted then servers the request through apache. Can anyone help me to do this? Faisal Abdullah Shibley

You can use runInteraction to get at the cursor directly (see the example I just posted for another message). The cursor is wrapped by the transaction object passed as the first argument to the interaction callback. trans.execute('select blah blah blah') desc = trans.description dave ---- Original Message ---- From: Mauro Colorio Date: Mon 6/14/04 3:15 To: Twisted-Python(a)twistedmatrix.com Subject: [Twisted-Python] Again about query mapped I saw in the list messages about mapping query results, it's a need for me too:) I found this useful script http://opensource.theopalgroup.com/files/db_row.txt I can't access to the patches today (is a temporary problem?) so I can't know if the patch sent by Stephen is derived from that module, but I found it very usefull and with very good performance (read the intro of the module), I'm not a lawyer but the license seems compatible with LGPL. the problem to use it over adbapi right now is that in adbapi I can't access to the cursor.description, how I can reach it? it seems Stepen's patch make it possible, but I can't access to his code.
